(14) Hereinafter, a locking device for a glove box for a vehicle according to an exemplary embodiment of the present invention will be described with reference to the drawings.

(15) FIG. 1 is a front perspective view illustrating a glove box door of a glove box for a vehicle according to an exemplary embodiment of the present invention, FIG. 2 is a rear perspective view illustrating the glove box door of the glove box for a vehicle according to the exemplary embodiment of the present invention, and FIG. 3 is a view illustrating a state in which the glove box door is unlocked.

(16) Referring to FIGS. 1 to 3, the glove box for a vehicle according to the exemplary embodiment of the present invention includes a glove box door 1 which is disposed in front of a front passenger seat in the vehicle. Here, the glove box door 1 is installed openably and closably in an instrument panel in the interior of the vehicle so as to accommodate articles.

(17) Hinge coupling portions 3 are formed at a lower end of the glove box door 1. The glove box door 1 may be rotatably coupled to a glove box housing (not illustrated) coupled to the instrument panel by inserting a pin (not illustrated) into the hinge coupling portions 3.

(18) The glove box door 1 has an accommodating space 5 formed at a rear side of the glove box door 1 in order to accommodate articles, and when the glove box door 1 is in a closed state, the accommodating space 5 is inserted and disposed in the instrument panel.

(19) A knob device 10 and a locking unit 20, which lock or unlock the glove box door 1 with respect to the glove box housing (not illustrated), are mounted in the glove box door 1.

(20) The knob device 10 includes a knob 12 which is pressed by a user in order to open and close the glove box door 1, and a push rod 14 which is connected with the knob 12 and slidably installed in the glove box door 1. The knob 12 is disposed on a front surface of the glove box door 1, and the push rod 14 is disposed in the glove box door 1. The knob device 10 will be described in detail with reference to FIGS. 4 to 12, and the locking unit 20 will be briefly described.

(21) The locking unit 20 includes a left locking rod 22, a right locking rod 24, and a rotating body 26 which are disposed in the glove box door 1.

(22) When the glove box door 1 is in the closed state, an end of the left locking rod 22 protrudes to the left side of the glove box door 1, and an end of the right locking rod 24 protrudes to the right side of the glove box door 1. Protruding portions of the left locking rod 22 and the right locking rod 24 may be inserted into a structure of the vehicle, and may be caught to prevent the glove box door 1 from being opened. Here, the structure of the vehicle by which the left locking rod 22 and the right locking rod 24 are caught may be the glove box housing (not illustrated) that is installed in the instrument panel so that the glove box door 1 may be inserted into the glove box housing.

(23) The left locking rod 22 is disposed at the lower side of the rotating body 26, the right locking rod 24 is disposed at the upper side of the rotating body 26, and the push rod 14 is disposed at the right side of the rotating body 26. The rotating body 26 is formed in a circular shape, and a plurality of gear teeth 26a is formed around the rotating body 26. Gear teeth 22a, which engage with the gear teeth 26a of the rotating body 26, are formed on an upper surface of the left locking rod 22, a plurality of gear teeth 24a, which engages with the gear teeth 26a of the rotating body 26, is also formed on a lower surface of the right locking rod 24, and a plurality of gear teeth 14a, which engages with the gear teeth 26a of the rotating body 26, is also formed on a left surface of the push rod 14. Therefore, when the user presses the knob 12, the push rod 14 slides into the glove box door 1, the rotating body 26 is thereby rotated, and the left locking rod 22 and the right locking rod 24 are inserted into the glove box door 1, such that the glove box door 1 may be unlocked and opened.

(24) Because the rotating body 26 needs to engage with the push rod 14 as well as the left locking rod 22 and the right locking rod 24, the rotating body 26 may have a sufficient thickness.

(25) The push rod 14, the rotating body 26, the left locking rod 22, and the right locking rod 24 all engage using the gear teeth, as described above, such that the user's force for pressing the knob 12 is transmitted to the left locking rod 22 and the right locking rod 24 without loss, thereby improving operational sensitivity.

(26) Hereinafter, the knob device 10 will be described in detail.

(27) FIG. 4 is a rear perspective view illustrating a knob device illustrated in FIG. 1, FIG. 5 is a rear view illustrating a part of FIG. 4, FIG. 6 is a view illustrating the configuration of FIG. 4 except for a push rod housing, FIG. 7 is a view illustrating the interior of the push rod housing illustrated in FIG. 3, FIG. 8 is an operational view of FIG. 7, FIG. 9 is a cross-sectional view taken along line A-A of FIG. 4, and FIG. 10 is a view illustrating another exemplary embodiment of FIG. 9.

(28) Referring to FIGS. 4 to 10, the knob device 10 includes a push rod housing 30 which is fixed to the glove box door 1, the push rod 14 which is slidably disposed in the push rod housing 30, and a guide rod 40 which is coupled to the push rod 14 and moved along an outer surface of the push rod housing 30 when the push rod 14 slides.

(29) When the push rod 14 slides by the user's force for pressing the knob 12, the guide rod 40 is moved along the upper surface of the push rod housing 30 so as to allow the push rod 14 to slide without shaking, thereby improving sensitivity when the user manipulates the knob 12.

(30) The push rod housing 30 includes an upper housing 32, and a lower housing 34 which is coupled to a lower portion of the upper housing 32. The upper housing 32 and the lower housing 34 have therein a vacant space so that the push rod 14 may slide in the space. Therefore, as illustrated in FIG. 7, when the push rod 14 is inserted into the lower housing 34, and thereafter, the upper housing 32 is coupled to the lower housing 34, the push rod 14 may be slidably disposed in the push rod housing 30.

(31) Referring to FIGS. 6 and 9 for a moment, a groove 14b is formed in an upper surface of the push rod 14, and a protruding portion 30b is formed on an inner surface of the push rod housing 30. The protruding portion 30b is inserted and disposed in the groove 14b, and as a result, when the push rod 14 slides, the push rod 14 slides without shaking while being guided by the protruding portion 30b and the groove 14b.

(32) However, referring to FIG. 10, it can be seen that FIG. 10 is different from FIG. 9. That is, on the contrary to FIG. 9, in FIG. 10, a protruding portion 14c is formed on the upper surface of the push rod 14, and a groove 30c is formed in the inner surface of the push rod housing 30, such that the same effect as the exemplary embodiment illustrated in FIG. 9 may be obtained. Hereinafter, only the exemplary embodiment illustrated in FIG. 9 will be described as an example.

(33) Referring to FIGS. 4 to 8, the push rod 14 includes a first rod portion 15 which has the gear teeth 14a formed at a side surface of the first rod portion 15, and is disposed in the push rod housing 30, and a second rod portion 16 which penetrates the push rod housing 30.

(34) A part of the first rod portion 15 is disposed in the push rod housing 30, and the remaining portion of the first rod portion 15 protrudes to the outside from the push rod housing 30 and is coupled to the knob 12.

(35) The first rod portion 15 is formed to have a quadrangular cross section, and the groove 14b is formed in the upper surface of the first rod portion 15.

(36) The second rod portion 16 is formed to have a circular cross section, and have a smaller cross-sectional area than the first rod portion 15.

(37) The second rod portion 16 is formed to be elongated at one end of the first rod portion 15, and a coupling portion 15a, which is coupled to a back surface of the knob 12, is formed at the other end of the first rod portion 15.

(38) The knob 12 is formed to have a larger area than the coupling portion 15a so as to allow the coupling portion 15a of the push rod 14 to be invisible from the interior side of the vehicle.

(39) When the user presses the knob 12, and thereby, the push rod 14 slides, the one end of the second rod portion 16 protrudes to the outside from the push rod housing 30, and guides the push rod 14 so that the push rod 14 may slide without shaking.

(40) An elastic member 18 is further disposed in the push rod housing 30. The elastic member 18 is disposed around the second rod portion 16.

(41) When the push rod 14 slides, the elastic member 18 is compressed between the first rod portion 15 and the push rod housing 30. That is, in a state illustrated in FIG. 8 after the user presses the knob 12 in a state illustrated in FIG. 7, the elastic member 18 is compressed and pushes the first rod portion 15, and as a result, the push rod 14 may slide toward an original position.

(42) FIG. 11 is a view illustrating part A partitioned by a dotted line in FIG. 6, and FIG. 12 is a cross-sectional view taken along line B-B of FIG. 11.

(43) Referring to FIGS. 4, 11, and 12, in a case in which the knob device 10 has a small size, the push rod 14 may slide without shaking by the configuration of the exemplary embodiment illustrated in FIGS. 9 and 10 even though there is no guide rod 40. However, in a case in which the knob device 10 has a large size, it is necessary to additionally assemble the guide rod 40 to the knob device 10 as necessary.

(44) In order to easily assemble the guide rod 40 to the back surface of the knob 12, the guide rod 40 includes a fixing member 42 which is coupled to the push rod 14, a guide member 44 which is spaced apart from the fixing member 42 and movably disposed on the outer surface on the push rod housing 30, and a connecting member 46 which connects the fixing member 42 and the guide member 44.

(45) In the present exemplary embodiment, the fixing member 42 is coupled to the coupling portion 15a coupled to the back surface of the knob 12, but the fixing member 42 may be coupled directly to the back surface of the knob 12. The fixing member 42 may be coupled to the coupling portion 15a by a screw.

(46) The fixing member 42 and the guide member 44 are formed in a hexahedron shape, and the connecting member 46 is formed in a long bar shape having a circular cross section.

(47) An insertion groove 42a into which the connecting member 46 is inserted is formed in the fixing member 42, and a through hole 44a through which the connecting member 46 passes is formed in the guide member 44.

(48) The fixing member 42 is first coupled to the coupling portion 15a, the connecting member 46 then passes through the through hole 44a of the guide member 44, and thereafter, one end of the connecting member 46 is fitted into the insertion groove 42a of the fixing member 42, thereby easily assembling the guide rod 40 to the push rod 14.

(49) A rib 46a is formed on an outer surface of the connecting member 46. The rib 46a is formed to be elongated along a length of the connecting member 46. Three ribs 46a are formed around the connecting member 46.

(50) When the guide rod 40 is completely assembled to the push rod 14, the rib 46a is caught by the fixing member 42 and the guide member 44, thereby preventing the guide member 44 and the connecting member 46 from being rotated. Therefore, when the user presses the knob 12, and thereby, the push rod 14 slides, the guide member 44 is moved along the upper surface of the push rod housing 30 without being rotated, thereby allowing the push rod 14 to slide without rattling.

(51) An operation of the glove box for a vehicle according to the exemplary embodiment of the present invention, which is configured as described above, will be described below.

(52) First, the case in which the guide rod 40 is not installed, the groove 14b is formed in the push rod 14, and the protruding portion 30b is formed on the push rod housing 30, as illustrated in FIG. 9, or the case in which the protruding portion 14c is formed on the push rod 14, and the groove 30c is formed in the push rod housing 30, as illustrated in FIG. 10, will be described below.

(53) When the user presses the knob 12 in order to open the glove box door 1, the push rod 14 slides in the push rod housing 30.

(54) In this case, the push rod 14 slides without shaking while being guided by the protruding portion 30b or 14c, and the groove 14b or 30c, thereby improving operational sensitivity when the user presses the knob 12.

(55) Second, the case in which the guide rod 40 is additionally installed in the state illustrated in FIG. 9 or 10 will be described below.

(56) When the user presses the knob 12 in order to open the glove box door 1, the push rod 14 slides in the push rod housing 30, and the guide member 44 of the guide rod 40 slides along the upper surface of the push rod housing 30.

(57) In this case, the push rod 14 slides without rattling while being guided by the protruding portion 30b or 14c, and the groove 14b or 30c, and the guide member 44 slides in a state in which the guide member 44 is in contact with the upper surface of the push rod housing 30, such that the push rod 14 slides more stably without rattling, thereby further improving operational sensitivity when the user presses the knob 12.

(58) Third, the case in which the protruding portion 30b or 14c, and the groove 14b or 30c are not formed on/in the push rod 14 and the push rod housing 30, but only the guide rod 40 is installed will be described below.

(59) When the user presses the knob 12 in order to open the glove box door 1, the push rod 14 slides in the push rod housing 30, and the guide member 44 of the guide rod 40 slides along the upper surface of the push rod housing 30.

(60) In this case, the push rod 14 may shake, but since the guide member 44 slides in a state in which the guide member 44 is in contact with the upper surface of the push rod housing 30, the push rod 14 does not shake, thereby improving operational sensitivity when the user presses the knob 12.

(61) According to the glove box for a vehicle according to the present invention, when the user presses the knob 12, the push rod 14 slides without shaking, thereby improving operational sensitivity when the user presses the knob 12, and preventing the knob 12 from rattling due to vibration of the vehicle when the vehicle travels.

(62) It may be understood to the person skilled in the art that the present invention may be implemented as other specific forms without changing the technical spirit or the essential characteristics. Thus, it should be appreciated that the exemplary embodiment described above is intended to be illustrative in every sense, and not restrictive. The scope of the present invention is represented by the claims to be described below rather than the detailed description, and it should be interpreted that all the changes or modified forms, which are derived from the meaning of the scope of the claims, the scope of the claims, and the equivalents thereto, are included in the scope of the present invention.
