Description

[0042] The invention will be explained only by way of example in the following with reference to possible embodiments and to the drawing. There are shown:

[0043] FIG. 1A an exemplary lock having a locking mechanism and a blocking device in a locked and blocked state;

[0044] FIG. 1B the lock of FIG. 1A in an unlocked and unblocked state;

[0045] FIG. 2 a flowchart relating to the opening of the lock of FIG. 1;

[0046] FIG. 3 a flowchart relating to the removal of an energy store from the lock of FIG. 1;

[0047] FIG. 4 a flowchart relating to the closing of the lock of FIG. 1; and

[0048] FIG. 5 a flowchart relating to the setting of the lock of FIG. 1 into a sleep state.

[0049] FIGS. 1A and 1B show purely by way of example a lock 10 of a vehicle that may be operated in accordance with the invention. In FIG. 1A, the lock 10 is shown in a locked and blocked state and, in FIG. 1B, the lock 10 is shown in an unlocked and unblocked state.

[0050] The lock 10 comprises a locking mechanism having a latch 14 that is movable between a latched position (FIG. 1A) and an unlatched position (FIG. 1B). In this respect, a translational movement of the latch 14 along the direction of the arrow 16 is provided. In the latched position, the latch is in engagement with a counter-piece, not shown, that is held in a latching manner in the lock 10 by the latch 14. The counter-piece may be part of the lock 10, for example a closing hoop or a bolt of the lock 10, or may be arranged at an object external to the lock, for example, at a battery of the vehicle.

[0051] An actuation of the latch 14 takes place by means of an actuation element 18 comprising a push button 20. In its passive state, the actuation element 18 is in the latched position of the latch in accordance with FIG. 1A, i.e. the push button 20 is not pressed in. On an actuation, i.e. on a pressing in of the push button 20, the actuation element 18 is transferred along the direction of the arrow 22 into its active position. This is a translational actuation movement. The push button 20 is connected to a transmission section 24. A slot guide 26, in which pins 28 formed at the latch 14 are guided, is arranged in the transmission section 24. The translational actuation movement of the push button 20 (arrow 22) is transmitted to the latch 14 and is converted (arrow 16) into a translational movement of the latch 14 directed perpendicular to said translational actuation movement by the slot guide 26 and the pins 28.

[0052] The actuation element 18 cooperates with a spring 19 such that a transfer of the actuation element 18 to its active state takes place against the return force of the spring 19, whereby the spring 19 is preloaded. If the push button 20 of the actuation element 18 is released in its active state, it is automatically returned to its passive state by the return force of the spring 19. Since the latch 14 and the push button 20 are bidirectionally coupled to one another by the slot guide 26 and the pins 28, the latch 14 is entrained and transferred into its latched position on a transfer of the actuation element 18 to the passive state.

[0053] The lock 10 further has a blocking device 30 comprising a pin-like blocking element 32 and an electric motor actuator 34. By means of the actuator 34, the blocking element 32 may be adjusted along its longitudinal axis between a blocking position (FIG. 1A) and a release position (FIG. 1B) in which the blocking element 32 is received in the actuator. In the blocking position, the blocking element 32 projects from the actuator 34 at the side of the latch 14 and is in engagement with the latch 14, which is in the latched position, and a cut-out 36 of the transmission section 24. Thus, both an actuation of the push button 20 and a movement of the latch 14 are blocked by the blocking element 32 that is in the blocking position.

[0054] The blocking device 30 furthermore comprises a controlling device, not shown, that is configured to control the actuator 34 and thus to control the adjustment of the blocking element 32 between the blocking position and the release position. The blocking device 30 is configured for a wireless reception of control commands, in particular release and blocking commands. The blocking device 30 receives these control commands from a control device arranged outside the lock 10, for example, from its onboard computer of the vehicle (not shown).

[0055] The lock 10 in accordance with FIGS. 1A, 1B may, for example, be a frame lock, a case lock, a brake disk lock, or a seat compartment lock. In addition, the lock 10 may serve to secure an energy store, e.g. a battery, i.e. a battery lock.

[0056] In the following, an actuation sequence will be explained by way of example for a battery lock for securing an energy store in a battery compartment of an electric bicycle. FIG. 2 shows a flowchart of the processes that play a role in the opening 102 of the battery lock. The starting point is a battery lock with the energy store inserted, with the locking mechanism in the locked position, and with the blocking element 32 in the blocking position (cf. FIG. 1A). In the latched position, the latch 14 engages into a cut-out of the energy store and thus secures it in the battery compartment. For a control of the battery lock by a user, an onboard computer arranged outside the battery lock at the electric bicycle is provided with a software application and a touch-sensitive screen in the present embodiment example. A smartphone may generally also serve as the control device.

[0057] If the user intends to remove the energy store from the battery compartment, the user inputs a command for removing the energy store at the control device (step 104). During the travel of the vehicle, an adjustment of the blocking element 32 of the battery lock 10 into the release position is to be prevented under all circumstances—on the one hand, in order not to interrupt the energy supply of, for example, a drive motor of the vehicle, and, on the other hand, in order to avoid a vibration during the travel from unintentionally causing a movement of the latch 14 into the unlatched position, whereby a loss of the energy store would be imminent. In a query step, the control device therefore first determines the movement state of the electric bicycle (step 106).

[0058] The movement state may, for example, be determined from a speed of rotation of a drive motor of the electric bicycle and/or by querying a sensor provided for this purpose. Alternatively, a determination of the movement state may be provided based on GPS data. If the query step 106 reveals that the electric bicycle is stationary, the control device transmits a release command to the blocking device 30 (step 110). Otherwise, if the query step 106 reveals that the electric bicycle is in motion, the control device does not transmit a release command to the blocking device 30, but informs the user by means of an error message on the screen of the onboard computer that an opening of the battery lock 10 is not possible (step 114).

[0059] The blocking device 30, in particular a controlling device of the blocking device 30, receives the release command transmitted by the control device (step 116). Provision may be made that an authentication process takes place (step 118) in which the control device authenticates itself at the controlling device of the blocking device before the latter processes the release command. Alternatively or additionally, provision may be made that the release command transmitted by the control device is decrypted by the controlling device (step 120).

[0060] In step 122, in response to the release command, the controlling device activates the actuator 34 of the blocking device 30, which moves the blocking element 32 into its release position (step 124), while the actuation element 18 and the latch 14 remain for the time being in their passive state or their latched state. Provision may be made that a status message is output (step 126) on the display of the onboard computer and informs the user that the blocking element 32 has been adjusted into the release position and that an unlocking of the locking mechanism is possible.

[0061] The user then presses the push button 20 (step 128) and thus transfers the actuation element 18 from its passive state to its active state (step 130), whereby the latch 14 is moved from the latched position into the unlatched position (step 132). The latch 14 is in this respect moved out of the cut-out of the energy store and no longer secures said energy store in the battery compartment. The user may then remove the energy store from the battery compartment (step 134).

[0062] As shown in FIG. 3, the user releases the push button 20 again (step 136) after the user has removed the energy store from the battery compartment. The push button 20 is transferred to its passive state (step 138) by the spring 19 shown in FIGS. 1A, 1B. At the same time, the latch 14 is entrained into its latched position by the slot guide 26 (step 140). The blocking element 32, in contrast, remains in its release position in the absence of the energy store, i.e. in the absence of the counter-piece. The battery lock is so-to-say in a standby state 142 in which the insertion of the energy store is possible at any time.

[0063] In FIG. 4, it is schematically shown which processes play a role in the closing 156 of the lock, i.e. when the user, for example after a charging process, reinserts the energy store into the battery compartment to secure it therein. The starting point is that the battery lock is in the standby state 142, i.e. the blocking element 32 is in its release position, the actuation element 18 is in its passive state, and the locking mechanism is in its locked position.

[0064] The user first inserts the energy store, i.e. the counter-piece, into the locking mechanism (step 158). During the insertion, the energy store comes into contact with the latch 14, in particular with a chamfered end face 15 of the latch 14, whereby said latch 14 is successively pressed into its unlatched position by the insertion movement of the energy store (step 160). At the same time, the actuation element 18 is entrained via the pins 28 and the slot guide 26 and is transferred from the passive state to the active state (step 162). In addition, the spring 19 is preloaded.

[0065] When the energy store approaches its fully inserted position, the latch 14 may engage into a cut-out of the energy store provided for this purpose and is thus no longer forced into the unlatched position by the energy store. As soon as this force is omitted, the actuation element 18 is transferred to its passive state by the preloaded spring 19 (step 164) and the latch 14 is in this respect entrained into its latched position (step 166). In the latched position, the latch 14 is now in engagement with the energy store such that it may no longer be removed from the battery compartment.

[0066] To block the locking mechanism in the locked position now reached, an adjustment of the blocking element 32 into its blocking position is to take place. First, to avoid malfunctions of the lock, a determination is made whether all the requirements for the adjustment of the blocking element 32 into the blocking position are met, namely whether the energy store is fully inserted into the battery compartment, whether the latch is in the latched position, and whether the actuation element is in the passive state. For this purpose, the battery lock has a sensor device for detecting the position of the counter-piece, i.e. of the energy store, of the latch 14, and/or of the actuation element 18. The sensor device may have one or more sensors, for example, stop sensors or switches.

[0067] In the embodiment example shown, provision is made that the determination of the position of the counter-piece, i.e. of the energy store, is detected without an additional sensor. Rather, the position of the energy store is to be detected by querying the existence of an electrical contact between the energy store and the blocking device (step 168). A successful establishing of the electrical contact in this case serves as a confirmation that the energy store has been fully inserted into the battery lock.

[0068] The insertion of the energy store into the battery lock may take place with the onboard computer deactivated and generally without the battery lock being connected to an energy supply. Provision may therefore be made that the successful establishing of the electrical contact activates the onboard computer of the vehicle (step 172) or that a connection, in particular a wireless connection, is established between the blocking device 30 of the battery lock and the onboard computer.

[0069] If the insertion of the energy store into the battery lock is confirmed, the position of the latch 14 is detected in a query step 174 and the position of the actuation element 18 is detected in a further query step 176. This may in each case take place by stop sensors or switches that may, for example, be actuated by the latch 14 and the actuation element 18 in the latched position and in the active state. If the query steps 174, 176 reveal that the latch 14 and/or the actuation element 18 is/are not in the intended position, a corresponding error message may be output (step 180), for example, on the screen of the onboard computer.

[0070] If it is confirmed by the sensor query that the latch 14 is in the latched position and the actuation element 18 is in the passive state, the time duration is recorded in a step 184 that has elapsed since the transfer of the counter-piece into its intended position, the transfer of the latch 14 into the latched state, and/or the transfer of the actuation element 18 to its passive state.

[0071] Only when a predetermined time period has elapsed in each case will a closing of the blocking element 32 be initiated in step 188. In this respect, provision may be made that each of the described sensor queries is performed and evaluated by the controlling device of the blocking device. If the sensor query reveals a deviation from the expected result, the controlling device may forward this via a wireless connection to the control device that then indicates a corresponding error message.

[0072] Alternatively, the sensor queries may be performed and evaluated by the control device. In this case, the control device only forwards a blocking command for adjusting the blocking element 32 into the blocking position to the blocking device 30 when all the sensor queries provide the expected result. Alternatively, the control device outputs an error message.

[0073] Provision may also be made that the user actively triggers the closing of the blocking element 32 after the insertion of the energy store by an input at the onboard computer (step 190). In this case, provision may additionally be made that the positions of one or more components of the battery lock and/or of the energy store are queried as described above to prevent malfunctions of and damage to the lock.

[0074] If the user moves away from the vehicle, provision may thus be made that the user removes the onboard computer from the electric bicycle (step 144) to deactivate the electric bicycle and to protect it against an unauthorized access (see FIG. 5). Alternatively, a switching off of the onboard computer or a disconnection of a wireless connection between the onboard computer and the battery lock may also be provided.

[0075] In this case, the battery lock is set into a sleep state. In a step 146, a determination is for this purpose first made whether a counter-piece, i.e. the energy store in the case of the battery lock, is in engagement with the locking mechanism, for example, via stop sensors or position sensors, via a query of an electrical contact that may be established by the counter-piece, or via a position of a switch that may be actuated by the counter-piece.

[0076] If the absence of a counter-piece of the battery lock is determined, the blocking element 32 thus remains in its release position or, if said blocking element 32 is not in the release position, it is adjusted into the release position (step 150). Thus, in the sleep state, the battery lock is also in a standby state in which the insertion of the energy store is directly possible, in particular without a prior user action or provision of a power supply for actuating the actuator 34 of the blocking device.

[0077] If a counter-piece is detected in the battery lock, the blocking element remains in its blocking position or, if said blocking element is not already in the blocking position, it is adjusted into the blocking position (step 154). The energy store inserted into the battery compartment is thus also securely protected against an unauthorized removal or a loss in the sleep state. In the sleep state, irrespective of the position of the blocking element 32, the push button is in its passive state and the locking mechanism is accordingly in its locked position.
