    DETAILED DESCRIPTION

    [0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

    [0018] Referring to FIGS. 1 and 2, a key cylinder device 20 according to an embodiment of the present invention is attached to a door 1 of a vehicle, and switches a door lock device 10 attached to the same door 1 from a locked state to an unlocked state to allow the door 1 to be opened by an operation of a handle 5.

    [0019] The key cylinder device 20 of the present embodiment is used for a left side door whose hinge shaft extends in the vehicle height direction. However, the key cylinder device 20 may be used for a right side door, a slide door, or a back door.

    [0020] An X direction in the accompanying drawings is a vehicle length direction, a direction indicated by an arrow is a front side, and a direction opposite to the arrow is a rear side. A Y direction is a vehicle width direction, and a direction indicated by an arrow is an inner side (vehicle interior side), and a direction opposite to the arrow is an outer side (vehicle exterior side). A Z direction is a vehicle height direction, and a direction indicated by an arrow is an upper side, and a direction opposite to the arrow is a lower side.

    [0021] Referring to FIGS. 1 and 2, the key cylinder device 20 is mechanically connected to the door lock device 10. The door lock device 10 is communicably connected to an electronic control unit (ECU) 6 mounted on the vehicle. An antenna 7 for performing wireless communication with an electronic key (not illustrated) carried by the user and an authentication unit 8 for performing key authentication are connected to the ECU 6.

    [0022] The ECU 6 includes a calculation unit, a storage unit, and a communication unit (not illustrated), reads a program stored in advance in the storage unit, and executes information processing according to steps instructed by the program. When the key authentication by the authentication unit 8 is established, the ECU 6 electrically operates the door lock device 10 based on an input signal from the handle 5. On the other hand, when the key authentication by the authentication unit 8 is not established, the ECU 6 does not operate the door lock device 10 even if the signal is input from the handle 5.

    [0023] Describing the outline of a door latch device 10, the door lock device 10 is disposed along an end panel 4 in a space defined by an outer panel 2, an inner panel 3, and an end panel 4 of the door 1. The door lock device 10 includes a latch mechanism 11, an actuator 12, a latch switching mechanism 13, a lock mechanism 14, an actuator 15, and a lock switching mechanism 16.

    [0024] The latch mechanism 11 includes a fork and a claw and can be switched between a latched state and an unlatched state. In the latched state, the fork holds the striker of the vehicle body and holds the door 1 in the closed state. In the unlatched state, the fork releases the striker, allowing the door 1 to be opened.

    [0025] The lock mechanism 14 is configured by a plurality of levers or the like and can be switched between an unlocked state and a locked state. In the unlocked state, the latch mechanism 11 can be switched from the latched state to the unlatched state via the latch switching mechanism 13. In the locked state, the latch mechanism 11 can be switched from the latched state to the unlatched state via the latch switching mechanism 13.

    [0026] The latch mechanism 11 is switched from the unlatched state to the latched state by the entry of the striker into the fork when the door 1 in the open state is closed. The switching of the latch mechanism 11 from the latched state to the unlatched state from the outside of the vehicle is performed by ECU 6 electrically via the latch switching mechanism 13 in response to a signal input from a switch 5a that has detected the normal opening operation of the handle 5 in a normal state in which the actuator 12 can be operated. On the other hand, in an emergency state in which the actuator 12 cannot be operated, the switching of the latch mechanism 11 from the latched state to the unlatched state from the outside of the vehicle is manually performed via the lock mechanism 14 and the latch switching mechanism 13 by an emergency opening operation of the handle 5 by the user.

    [0027] The switching (locking) of the lock mechanism 14 from the unlocked state to the locked state from the outside of the vehicle is performed by the ECU 6 electrically in response to a signal input from a switch 5b that has detected the locking operation of the handle 5 in a normal state in which the actuator 15 can be operated. The switching (unlocking) of the lock mechanism 14 from the locked state to the unlocked state from the outside of the vehicle is normally performed by the ECU 6 electrically by a signal input from the switch 5a that has detected the normal opening operation of the handle 5. On the other hand, in an emergency state in which the actuator 15 cannot be operated, the switching of the lock mechanism 14 from the locked state to the unlocked state from the outside of the vehicle is manually performed via the lock switching mechanism 16 by an emergency operation (unlock operation) of the key cylinder device 20 by the user.

    [0028] As described above, the key cylinder device 20 is not used in a normal state in which the actuator 15 can be operated. Therefore, the key cylinder 32 included in the key cylinder device 20 is disposed at the lower end portion 2a of the outer panel 2 below the user's eye line so as not to impair the designability of the door 1. The lower end portion 2a is a region on the lower side of a half of the total height of the outer panel 2, and is a portion inclined to the inner side in the vehicle width direction toward the lower side.

    [0029] Hereinafter, the key cylinder device 20 of the present embodiment will be specifically described.

    [0030] Referring to FIGS. 1, 3, and 4, the key cylinder device 20 includes a cylinder unit (cylinder mechanism) 30, a connection unit (connecting mechanism) 40, and a cable 25 that mechanically connects the cylinder unit 30 and the connection unit 40.

    [0031] In the key cylinder device 20, a portion other than the distal end of the key cylinder 32 included in the cylinder unit 30 is disposed in the space between the outer panel 2 and the inner panel 3 in the door 1 and is invisible from the outside of the door 1. In the key cylinder device 20, only the distal end of the key cylinder 32 can be exposed to the outside of the vehicle. At a normal time, the distal end of the key cylinder 32 is preferably covered by the decorative member of the door 1 and exposed by the operation by the user.

    Configuration of Cable

    [0032] Referring to FIGS. 1, 3, and 4, the cable 25 includes a tube 26 and a wire (pulling member) 27 each having flexibility. The wire 27 is a transmission member for transmitting the operating force of the key cylinder 32 to the door lock device 10 via the connection unit 40. The wire 27 is movably inserted into the tube 26, and can advance and retract in conjunction with the turning of the key cylinder 32. Wire ends 28 are respectively fixed to both ends of the wire 27. Of the pair of wire ends 28, one located at the lower end is connected to the cylinder unit 30, and the other located at the upper end is connected to the connection unit 40.

    Configuration of Cylinder Unit

    [0033] Referring to FIGS. 3 to 5, the cylinder unit 30 is a configuration for unlocking the door lock device 10 from the outside of the door 1 illustrated in FIG. 1. The cylinder unit 30 includes a casing 31, a key cylinder 32, a turning mechanism 34, an anti-theft cover 37, a waterproof cover 38, and a waterproof cap 39. Among them, the turning mechanism 34 includes a driving lever 35 and a driven lever (turning member) 36.

    [0034] The casing 31 is a configuration for attaching the cylinder unit 30 to the outer panel 2 illustrated in FIG. 1. The casing 31 includes a main body portion 31a, an attachment portion 31b, and a shaft portion 31c.

    [0035] The body portion 31a has a cylindrical shape and turnably supports the key cylinder 32 therein. An axis line A of the body portion 31a is inclined to the outer side in the vehicle width direction toward the lower side, but extends in the vehicle height direction as a whole. The attachment portion 31b is a configuration for attaching to the outer panel 2 illustrated in FIG. 1, and protrudes toward both sides in the vehicle length direction from the body portion 31a. The shaft portion 31c is a configuration for attaching the driven lever 36 and protrudes to the outer side in the vehicle width direction from the main body portion 31a. The axis line B of the shaft portion 31c extends in a direction orthogonal to the axis line A of the main body portion 31a.

    [0036] The key cylinder 32 includes a key hole 32a into which a regular mechanical key (not illustrated) can be inserted. The key cylinder 32 is turnably attached to the main body portion 31a of the casing 31 and is disposed at the lower end portion 2a of the outer panel 2 illustrated in FIG. 1 so that the key hole 32a is directed to the lower side (road surface).

    [0037] The key cylinder 32 is turnable between an initial position (non-operation position) illustrated in FIGS. 1 and 5 and an unlocking position (operation position) turned from the initial position by an angle defined in a direction D1 (clockwise in FIG. 1) illustrated in FIG. 4 by an operation of the mechanical key. When the key cylinder 32 is turned to the initial position, the lock mechanism 14 illustrated in FIG. 2 cannot be switched. When the key cylinder 32 is turned from the initial position to the unlocking position, the lock mechanism 14 is switched from the locked state to the unlocked state via the lock switching mechanism 16 illustrated in FIG. 2. Note that the transmission of the operating force of the key cylinder 32 to the lock mechanism 14 illustrated in FIG. 2 will be described in detail later.

    [0038] The key cylinder 32 is biased from the unlocking position to the initial position by a spring (first biasing member) 33. One end of the spring 33 is locked to the casing 31, and the other end of the spring 33 is locked to the key cylinder 32.

    [0039] The driving lever 35 is integrally turned around the axis line A in the same direction as the key cylinder 32 by the turning of the key cylinder 32. Specifically, the driving lever 35 is attached to the upper end portion 32b of the key cylinder 32 so as not to be relatively movable in both the axial direction and the circumferential direction of the key cylinder 32. The rotation axis (first rotation axis) of the driving lever 35 coincides with the axis line A of the casing 31 and the rotation axis of the key cylinder 32. The driving lever 35 is provided with an engagement portion 35a for engaging the driven lever 36 so as to project out to the outer side in the vehicle width direction.

    [0040] The driven lever 36 is disposed adjacent to the driving lever 35 and is turnable in conjunction with the turning of the driving lever 35. Specifically, the driven lever 36 is disposed on the outer side in the vehicle width direction of the casing 31 and attached to the shaft portion 31c. This allows the driven lever 36 to turn about the axis line B of the shaft portion 31c that is a second rotation axis extending in a direction orthogonal to the axis line A of the casing 31 that is a first rotation axis of the driving lever 35.

    [0041] The driven lever 36 is provided with a to-be-engaged portion 36a to be engaged with the engagement portion 35a so as to project out to the upper side toward the driving lever 35. This causes, when unlocking the key cylinder 32 in the direction D1 illustrated in FIG. 4, the driven lever 36 to turn in the direction D2 by integrally turning the driving lever 35 in the same direction D1. The driven lever 36 is provided with a wire connecting portion 36b in order to pull the wire 27 downward by the turning in the direction D2. The wire connecting portion 36b includes a hole for connecting a wire end 28 at a lower end of the wire 27. The wire connecting portion 36b protrudes to the rear side in the vehicle length direction so as to be turned downward by the turning of the driven lever 36 in the direction D2.

    [0042] The anti-theft cover 37 is configured to prevent a third party from illegally operating the driving lever 35, the driven lever 36, and the wire 27. The anti-theft cover 37 is attached to the outer side in the vehicle width direction with respect to the casing 31 and covers the casing 31 including the key cylinder 32, the driving lever 35, the driven lever 36, and the lower end of the wire 27. This causes a member intended for picking to suppress the driving lever 35, the driven lever 36, and the wire 27 from being directly operated. The anti-theft cover 37 is provided with a holding portion 37a that positions and holds a tube end (not illustrated) attached to an end of the tube 26.

    [0043] The waterproof cover 38 is provided to prevent water from entering the casing 31. The waterproof cover 38 covers the main body portion 31a of the casing 31 including the key cylinder 32, the driving lever 35, the driven lever 36, and the lower end of the wire 27. Thus, water entering the door 1 from between the outer panel 2 and the inner panel 3 is prevented from adhering to the driving lever 35, the driven lever 36, and the lower end of the wire 27.

    [0044] The waterproof cap 39 is a configuration for preventing water from entering the key cylinder 32 through the key hole 32a. The waterproof cap 39 is a cylindrical body with one end opened and the other end closed, and is detachably attached to the outer end portion of the body portion 31a of the casing 31 including the key cylinder 32.

    Configuration of Connection Unit

    [0045] Referring to FIGS. 3, 4, and 6, the connection unit 40 is a configuration for connecting the cylinder unit 30 to the door lock device 10 by way of the wire 27. In the door 1 illustrated in FIG. 1, the connection unit 40 is disposed above the cylinder unit 30 with an interval, and is attached at a height position equivalent to that of the door lock device 10. The connection unit 40 includes a support member 41, a rod (connecting member) 42, and a connection lever 44.

    [0046] The support member 41 is a configuration for turnably supporting the rod 42, and attaching the connection lever 44 including the rod 42 to the attachment panel 3a (see FIG. 7) joined to the inner panel 3 illustrated in FIG. 1. The support member 41 includes a body portion 41a, an attachment piece 41b, and a holding portion 41c.

    [0047] The body portion 41a has a cylindrical shape and turnably supports the rod 42 therein. The axis line C of the main body portion 41a is inclined downward toward the inner side in the vehicle width direction but extends in the vehicle width direction as a whole. The attachment piece 41b is a configuration for attaching to the attachment panel 3a illustrated in FIG. 7, and a plurality of attachment pieces are provided at an end portion on the inner side in the vehicle width direction of the main body portion 41a at intervals in the circumferential direction. The holding portion 41c is configured to position and hold a tube end (not illustrated) attached to an end of the tube 26, and protrudes to the lower side from the main body portion 41a toward the connection unit 40.

    [0048] Referring to FIGS. 3, 4, and 7, the rod 42 is a configuration for connecting to a connection receiving portion 16a similar to the known connection receiving portion provided in the door lock device 10. The rod 42 has a rod shape and is attached to the main body portion 41a of the support member 41 so as to be allowed to turn about the axis line C. The axis line of the rod 42 coincides with the axis line C of the main body portion 41a due to the attachment to the support member 41. The entire length of the rod 42 is longer than the entire length of the body portion 41a. Both ends of the rod 42 protrude from both ends of the body portion 41a.

    [0049] A connecting portion 42a is provided at an end portion on the inner side in the vehicle width direction of the rod 42. The connecting portion 42a can be connected to the connection receiving portion 16a of the lock switching mechanism 16 illustrated in FIG. 2. The connecting portion 42a includes a plurality of projecting pieces radially projecting outward from the rod 42 in the radial direction, and can transmit the turning force of the rod 42 to the lock switching mechanism 16. Referring to FIGS. 3, 4, and 6, an attachment portion 42b to which the connection lever 44 is attached is provided at an end portion on the outer side in the vehicle width direction of the rod 42.

    [0050] The rod 42 and the support member 41 are provided with a restricting portion 43 for restricting the turning of the rod 42 with respect to the support member 41. The restricting portion 43 includes a flange portion 42c and a convex portion 42d provided on the rod 42, and a concave groove 41d provided on the support member 41.

    [0051] The flange portion 42c comes into contact with an end portion on the inner side in the vehicle width direction of the support member 41 and restricts an insertion position of the rod 42 with respect to the main body portion 41a. The convex portion 42d protrudes radially outward from the rod 42 and extends to the outer side in the vehicle width direction from the flange portion 42c.

    [0052] The concave groove 41d is configured by a notch provided at an end portion on the inner side in the vehicle width direction of the main body portion 41a of the support member 41. In the circumferential direction around the axis line C, the angular range in which the concave groove 41d is formed is wider than the angular range in which the convex portion 42d is formed. A clearance having a defined angular range is formed between a groove wall of the concave groove 41d and a side surface of the convex portion 42d. The angular range of the clearance is greater than or equal to the turning angle range necessary for the unlock operation of the lock mechanism 14 illustrated in FIG. 2 and is equally formed in the present embodiment.

    [0053] The connection lever 44 is a conversion member for converting the movement of the wire 27 in the advancing and retracting direction into the turning of the rod 42. The connection lever 44 is provided with an attachment hole 44a into which the attachment portion 42b can be inserted. The turning of the lever 44 with respect to the attachment portion 42b is restricted by, for example, penetration of a coupling pin (not illustrated). Thus, the connection lever 44 is turnable integrally with the rod 42.

    [0054] The connection lever 44 includes a connecting portion 44b for connecting the wire end 28 at the upper end of the wire 27. The connecting portion 44b protrudes to the outer side in the radial direction of the rod 42, which is a direction orthogonal to the axis line C. A hole to which the connecting jig 45 can be attached is formed in the connecting portion 44b. The wire end 28 is attached to the hole in the 44b of the connecting portion via a connecting jig 45 so as not to be easily detached. Note that the connecting jig 45 is also preferably used for the wire connecting portion 36b of the cylinder unit 30.

    [0055] The connection lever 44 configured as described above is turnable from the initial position illustrated in FIGS. 3 and 4 to the operating position turned by an angle defined in a direction D3 (clockwise in FIG. 4) by the unlock operation of the lock mechanism 14 illustrated in FIG. 2.

    [0056] A spring (second biasing member) 46 that biases the connection lever 44 from the operating position to the initial position is disposed between the connection lever 44 and the support member 41. One end of the spring 46 is locked to the support member 41, and the other end of the spring 46 is locked to the connection lever 44.

    [0057] Next, the operation of the key cylinder device 20 will be described.

    [0058] When the key cylinder 32 is turned in the direction DI by the key operation, the driving lever 35 integrally turns in the direction D1. This causes the driven lever 36 to turn in the direction D2, and this turning causes the wire 27 to be pulled downward (in a first direction). As a result, the connection lever 44 turns in the direction D3, and the rod 42 turns integrally with the connection lever 44 in the direction D3. In this manner, the operating force of the key cylinder 32 is transmitted to the lock switching mechanism 16 illustrated in FIG. 2, whereby the lock mechanism 14 is switched from the locked state to the unlocked state.

    [0059] When the key operation is stopped, the key cylinder 32 turns from the unlocking position to the initial position by the biasing force of the spring 33. The rod 42 and the connection lever 44 turn from the operating position to the initial position by the biasing force of the spring 46. As a result, the wire 27 is pulled upward (second direction) by the biasing force of the springs 33 and 46.

    [0060] Here, since both the movement of the wire 27 to the initial position and the turning of the connection lever 44 are upward, a force for moving against gravity is required. The entire length of the cable 25 is long, and the cable 25 may be curved and routed in consideration of other members. As a result, the resistance between the tube 26 and the wire 27 increases, and thus a situation in which the connection lever 44 and the key cylinder 32 including the wire 27 cannot be returned to the initial positions only by the biasing force of the spring 33 disposed in the key cylinder 32 may occur. On the other hand, since the key cylinder device 20 of the present embodiment includes the two springs 33 and 46, the connection lever 44 and the key cylinder 32 including the wire 27 can be reliably returned to the initial positions.

    [0061] The key cylinder device 20 configured as described above has the following features.

    [0062] The key cylinder 32 is connected to the door lock device 10 via the wire 27 and the connection unit 40. Therefore, the operating force of the key cylinder 32 can be transmitted to the door lock device 10 via the wire 27. The key cylinder 32 can be disposed at a desired position of the door 1. In the key cylinder 32, a spring 33 that biases the key cylinder 32 from the unlocking position to the initial position is disposed. In the connection unit 40, a spring 46 that biases the wire 27 to move in the second direction is disposed. Therefore, even in a situation in which the resistance between the wire 27 and the tube 26 increases, the key cylinder 32 including the wire 27 can be reliably returned to the initial position.

    [0063] The connection unit 40 includes a support member 41 attachable to the door 1 of the vehicle and a rod 42 turnably supported by the support member 41 and connectable to the door lock device 10. This allows the key cylinder 32 to be disposed at a desired position of the door 1 and connected to the door lock device 10 without changing the configuration of the door lock device 10. The support member 41 is provided with a restricting portion 43 that restricts the turning of the rod 42 with respect to the support member 41. This allows, when assembling the support member 41 to the door 1, the support member to be assembled in a state where the groove shape of the connection receiving portion 16a of the door lock device 10 and the protruding shape of the connecting portion 42a of the rod 42 are matched with each other improving workability.

    [0064] The connection unit 40 has a connection lever 44 that is integrally and turnably attached to the rod 42 and is connected to the upper end of the wire 27. This can connect the key cylinder 32 to the door lock device 10 with a simple configuration, allowing an increase in manufacturing cost to be suppressed.

    [0065] The key cylinder 32 is disposed at the lower end portion of the door 1 of the vehicle. This causes the key cylinder 32 to be located below the user's eye line and makes it difficult to visually recognize, allowing the designability of the door 1 of the vehicle to be improved.

    [0066] The connection unit 40 is disposed above the key cylinder 32 at an interval. The cylinder unit 30 includes a spring 33 that returns the key cylinder 32 to the initial position. The connection unit 40 includes a spring 46 that returns the connection lever 44 to the initial position. Thus, the wire 27 and the connection lever 44 can be moved upward against the resistance between the tube 26 and the wire 27 and gravity. Therefore, not only the key cylinder 32 but also the connection lever 44 including the wire 27 can be reliably returned to the initial position against its own weight.

    [0067] A driven lever 36 which is turnable in conjunction with the turning of the key cylinder 32 and to which a lower end of the wire 27 is connected is provided. This can reliably transmit the operating force of the key cylinder 32 to the wire 27 and reliably unlock the door lock device 10 via the connection lever 44 and the rod 42.

    [0068] Note that the present invention is not limited to the configuration of the above-described embodiment, and various modifications can be made.

    [0069] For example, the biasing member that returns the key cylinder 32 including the wire 27 to the initial position is not limited to the two springs 33 and 46, and may be three or more springs or leaf springs, and can be changed as necessary.

    [0070] The configuration for converting the movement of the wire 27 in the advancing and retracting direction into the turning of the rod 42 is not limited to one connection lever 44, may be configured by a plurality of levers or turning members and can be changed as necessary.

    [0071] The restricting portion 43 may be configured such that the support member 41 is provided with the convex portion 42d and the rod 42 is provided with the concave groove 41d. The restricting portion 43 can be changed as necessary as long as the restricting portion 43 can restrict the turning of the rod 42 with respect to the support member 41.

    [0072] The turning member that transmits the rotational force of the key cylinder 32 to the wire 27 is not limited to the driven lever 36, and may be configured by the driving lever 35, and can be changed as necessary. The key cylinder 32 may have a configuration of switching the door lock device 10 from the unlocked state to the locked state by turning from the initial position (non-operation position) to the locked position (operation position).

    [0073] The cylinder unit 30 may be disposed on the upper side of the connection unit 40, or may be disposed spaced apart in the vehicle length direction at the same height position as the connection unit 40.
