This push-open type has a configuration in which a rail is provided on the side surface of the glove box, and a guide member is provided on the vehicle body side so as to be biased toward the rail and guided by the rail.

More specifically, an inner rail and an outer rail are provided on the side of the glove box, and the glove box is locked by dropping the guide member into the recess of the inner rail, and by pushing the lid, the guide member moves to the inner rail. The glove box is unlocked and opened by moving out of the recess and moving to the outer rail.

Patent No. 6258062

In the push-open type glove box disclosed in Patent Document 1, if the glove box is pushed excessively when the glove box is closed, the guide member jumps out of the depression of the inner rail and moves to the outer rail, causing the glove box to be opened again. I was afraid.

SUMMARY OF THE INVENTION In view of the above facts, it is an object of the present invention to provide an opening/closing mechanism for a glove box of a push-open type, which can be reliably closed even if the glove box is pushed excessively.

A glove box opening/closing mechanism according to the invention of claim 1 comprises: a glove box whose lower end is rotatably pivotally supported so that it can be opened and closed with respect to an opening of a vehicle interior member; The glove box is unlocked by pushing the glove box to a first pushed-in position on the inner side of the closed position, and the gloves are pushed into the opened glove box to a second pushed-in position on the inner side of the closed position. a push-open type opening/closing mechanism that locks the box and holds it at the closed position; an inhibition mechanism that prevents displacement of the glove box from acting on the opening/closing mechanism until the glove box reaches the excessively pushed-in position and returns to the second pushed-in position.

In this glove box opening/closing mechanism, the lower end of the glove box is pivotally supported so as to be swingable (rotatable) so that it can be opened and closed with respect to the opening of the vehicle interior component.

The opening/closing mechanism unlocks the glove box by pushing the glove box to a first pushed position on the far side of the closed position, and pushes the opened glove box to a second pushed position on the far side of the closed position. This is a push-open type that locks the glove box and holds it in the closed position.

When closing the glove box, if the glove box is pushed to the excessively pushed position on the back side of the second pushed position, the glove box is returned to the second pushed position by stopping the pushing of the glove box. At this time, the displacement of the glove box from the second pushed-in position to the over-pushed-in position and returning to the second pushed-in position does not act on the opening/closing mechanism due to the inhibition mechanism. Therefore, even if the glove box is pushed in excessively, the opening/closing mechanism can lock the glove box in the closed position in the same way as when pushed to the second pushed position.

That is, the glove box is prevented from being opened again by pushing the glove box excessively when closing the glove box.

A glove box opening/closing mechanism according to the invention of claim 2 is characterized in that in the glove box opening/closing mechanism of the invention of claim 1, the opening/closing mechanism is provided on a side plate portion of the glove box, and rotates the glove box. An engaging hole portion comprising a circumferential portion formed along the moving direction and an engaging portion extending in a direction intersecting the circumferential portion from the opening-side end of the glove box in the circumferential portion. an engaging convex portion inserted into the engaging hole portion; biasing means for biasing the engaging convex portion toward the circumferential direction portion in the locking portion; The locking of the engaging convex portion is released by pushing it to the first pushed position, and the engaging convex portion is locked to the locking portion by pushing the opened glove box to the second pushed position. and a locking mechanism.

In this opening/closing mechanism of the glove box, an engagement hole is provided in the side plate of the glove box. The engaging hole has a circumferential portion extending in the rotation direction of the glove box, and an engaging portion extending in a direction intersecting the circumferential portion from the opening-side end of the glove box in the circumferential portion. have.

An engagement projection operated by a lock mechanism is inserted into the engagement hole. Further, the engaging projection is biased toward the circumferential direction portion at the locking portion by biasing means.

When the glove box is pushed to the first push-in position on the back side of the closed position, the lock mechanism releases the locked state of the engagement protrusion. When the push-in of the glove box is stopped in this state, the engagement convex portion is moved by the biasing force of the biasing means to the circumferential side end portion of the locking portion of the engagement hole portion, that is, the open side end portion of the circumferential portion. ). As a result, the glove box can be swung (opened).

On the other hand, when closing the glove box, the opened glove box is pushed to the second pushed position on the back side of the closed position, that is, the engagement protrusion is engaged against the biasing force of the biasing means. It moves from the circumferential portion (the open side end thereof) of the joint hole portion to the locking portion. When the pushing of the glove box is stopped in this state, the engaging projection is locked by the engaging portion. That is, the glovebox is locked in the closed position.

When the glove box is pushed farther than the second pushing position (over-pushing), the engaging convex portion is displaced to the far side of the locking portion. , the glove box is returned to the position corresponding to the second pushed-in position, and the engaging projection is locked by the engaging portion by the same operation as described above. That is, the glovebox is locked in the closed position.

As a result, the glove box cannot be opened again due to over-pressing of the glove box when the glove box is closed.

The glove box opening/closing mechanism according to claim 3 is the glove box opening/closing mechanism according to claim 2, wherein the locking mechanism includes a shaft portion and an arm extending radially outward from one axial end side of the shaft portion. and the engaging projection extending from the arm in the axial direction of the shaft; and a link attached to the other axial end of the shaft and extending radially outward. a mechanism, a cam pin provided at an end of the link mechanism and extending in the axial direction, and an orbiting cam groove in which the cam pin is guided in one direction, the cam groove having the closed position; , the first pushed-in position, the open position where the engaging protrusion is located in the circumferential direction portion, the closed position groove corresponding to the second pushed-in position, the first pushed-in position groove, the open position groove, the second pushed-in position The grooves are arranged in sequence, and the biasing means biases the cam pin from the first pushed-in position groove toward the open position groove and from the second pushed-in position groove toward the closed position groove. ing.

In this opening/closing mechanism for the glove box, the lock mechanism has a lifter, a link mechanism, a cam pin, and a cam groove, and when the glove box is pushed from the closed position to the first pushing position, the engagement of the engagement hole is made. The lifter rotates in the other direction around the shaft portion against the biasing force of the biasing means due to the displacement of the engaging projection inserted into the stop portion. As a result, the cam pin attached to the tip of the link mechanism moves from the closed position groove portion of the cam groove to the first pushed position groove portion (the glove box is unlocked) against the biasing force of the biasing means. Furthermore, when the pushing into the glove box is stopped, the biasing force of the biasing means causes the cam pin to move from the first pushed position groove to the open position groove of the cam groove. As a result, the lifter rotates in one direction about the axis by the biasing force of the biasing means, the engaged portion of the lifter moves from the engagement portion of the engagement hole to the circumferential portion, and the glove box can be opened. be done.

On the other hand, by pushing the opened glove box to the second push-in position, the engaging convex portion moves from the circumferential portion of the engaging hole portion to the locking portion. Along with this movement, the lifter rotates about the axis in the other direction, and the cam pin moves from the open position groove portion of the cam groove to the second pushed position groove portion against the biasing force of the biasing means.

Here, when the pushing into the glove box is stopped, the biasing force of the biasing means moves the cam pin from the second pushed-in position groove portion of the cam groove to the closed position groove portion. In the closed position groove portion, the biasing means does not bias the cam pin toward the first pushed-in position groove portion, so the cam pin does not move from the closed position groove portion of the cam groove. As a result, the engaging convex portion of the lifter is locked by the locking portion of the engaging hole portion. That is, the glovebox is locked in the closed position.

In the glove box opening/closing mechanism according to claim 4, in the glove box opening/closing mechanism according to claim 3, the second pushed-in position groove portion includes a main body portion corresponding to the second pushed-in position and an excess portion of the glove box. An extension corresponding to pushing is provided in communication only with the main body.

In this glove box opening/closing mechanism, when the glove box is pushed excessively beyond the second pushing position when the glove box is closed, the engagement convex portion is further displaced at the locking portion of the engagement hole, and the lifter rotates. amount is excessive. At this time, the cam pin moves from the open position groove portion of the cam groove to the second pushed position groove portion against the biasing force of the biasing means, and further moves from the body portion to the extension portion in the second pushed position groove portion.

In this second push-in position groove, the extension communicates only with the main body. Therefore, when the glove box is pushed beyond the second pushed position, the cam pin only moves from the main body to the extension in the second pushed position groove.

Further, when the pushing of the glove box is stopped, the cam pin returns to the main body from the extension in the second push-in position groove by the biasing force of the biasing means, and moves from there to the closed position groove. As a result, the engaged portion is locked by the engaging portion of the engaging hole. That is, the glovebox is locked in the closed position.

In this way, since the extension portion communicates only with the main body portion in the second pushed-in position groove portion, the cam pin moved to the extension portion may move to another groove portion of the cam groove other than the second pushed-in position groove portion, for example, the first pushed-in position groove portion. The glove box is prevented from opening again by moving to the position groove.

In this way, when closing the glove box, even if the glove box is excessively pushed beyond the second pushed position, the glove box can be reliably closed without being opened again.

As described above, in the glove box opening/closing mechanism according to claims 1, 2, and 4, even if the glove box is pushed excessively when closing the glove box, the glove box can be reliably closed without being opened again.

In the glove box opening/closing mechanism according to claim 3, the glove box can be constructed compactly.

That is, in the cam groove portion 140 , the cam groove 98 is formed so as to go around the island portion 130 inside the peripheral wall 132 .

Furthermore, a partition wall 136 is formed extending from a portion of the peripheral wall 132 toward the island portion 130 (the center of the cam groove 98). The partition wall 136 separates (extends 98F2 of) a third groove portion 98F of the cam groove 98, which will be described later, from the base portion 98B.

The cam groove 98 has a base portion 98A, a base portion 98B, a first groove portion 98C, a bottom portion 98D, a second groove portion 98E, and a third groove portion 98F clockwise in FIG. 4 with the island portion 130 as the center.

Here, the base portion 98A is in the "closed position groove", the base portion 98B is in the "first push-in position groove", the bottom portion 98D is in the "open position groove", and the third groove 98F is in the "second push-in position groove". Equivalent to.

In the description of the cam groove 98 below, the left side in the vehicle width direction may be expressed as "high" or "upper", and the right side in the vehicle width direction may be expressed as "low" or "lower".

The base portion 98A is formed by cutting the vehicle front side of the island portion 130 rightward in the vehicle width direction. A base portion 98B lower than the base portion 98A is formed on the vehicle front side of the base portion 98A.

A first groove portion 98C is formed extending from the base portion 98B toward the vehicle rear side. A bottom portion 98D is formed on the vehicle rear side of the first groove portion 98C. The first groove portion 98C is an inclined surface that rises from the vehicle front (base portion 98B) side end portion toward the vehicle rear (bottom portion 98D) side end portion.

A second groove portion 98E is formed on the vehicle lower side of the bottom portion 98D. The second groove portion 98E extends downward in the vehicle from the bottom portion 98D and then extends forward in the vehicle to form a substantially R-shaped corner portion. In addition, the second groove portion 98E has an inclined surface that rises from one end portion on the side of the bottom portion 98D toward the other end portion.

A third groove portion 98F is formed on the vehicle front side of the second groove portion 98E. The third groove portion 98F extends from the second groove portion 98E side toward the vehicle front side. A body portion 98F1 on the vehicle rear side (second groove portion 98E) of the third groove portion 98F communicates with the base portion 98A. On the other hand, the extension portion 98F2 on the vehicle front side of the third groove portion 98F is surrounded by the peripheral wall 132 and the partition wall 136, and is isolated by the base portion 98B located above the vehicle and the partition wall 136 (communicates only with the main body portion 98F1). ing).

The extended portion 98F2 of the third groove portion 98F and the peripheral wall 132 surrounding the extended portion 98F2 and the partition wall 136 correspond to the "inhibition mechanism".

Further, as shown in the partial enlarged view of FIG. 4, between the base portion 98A and the base portion 98B, between the first groove portion 98C and the bottom portion 98D, between the second groove portion 98E and the third groove portion 98F, and between the third groove portion Steps 142A to 142D are formed between 98F and base portion 98A, respectively. The steps 142A to 142D prevent the guided portion 124 biased toward the bottom wall 84 from moving backward in the cam groove 98 in the counterclockwise direction in FIG. The direction of movement is limited to one direction so that the portion 124 moves clockwise in FIG.

(action)
The opening/closing operation of the glove box 12 by the glove box opening/closing mechanism 10 will be described.

First, the state in which the glove box 12 is closed will be described.

As shown in FIG. 11 , the engaging protrusion 76 formed at the tip of the arm 62 of the lifter 16 is positioned in the radial direction portion 34 of the engaging hole 30 of the glove box 12 .

On the other hand, as shown in FIG. 6A, the guided portion 124 of the second link pin 108 interlocking with the lifter 16 via the first link 102 and the second link 106 is positioned on the base portion 98A of the cam groove 98. ing. The first link 102 is biased in the arrow B direction around the axis AX by a torsion spring 110 . Therefore, the guided portion 124 connected to the first link 102 via the second link 106 is biased toward the island portion 130 side. That is, the guided portion 124 does not move from the base portion 98A to the base portion 98B or the third groove portion 98F. Thus, the guided portion 124 is prevented from moving, and the rotation of the lifter 16 and the displacement of the engaging convex portion 76 of the lifter 16 within the engaging hole portion 30 of the glove box 12 are prevented.

That is, the closed state of the glove box 12 is maintained (the glove box 12 is locked).

Next, the operation when the glove box 12 is opened will be described.

First, the glove box 12 is pushed from the closed position (see FIG. 11) to the first pushed-in position on the front side (back side) of the vehicle. As a result, as shown in FIG. 12 , the glove box 12 rotates (rocks) toward the vehicle front side about the shaft portion 28 . As a result, the engaging convex portion 76 of the lifter 16 located in the radial portion 34 of the engaging hole portion 30 of the glove box 12 is displaced toward the vehicle front side, and the lifter 16 rotates in the direction of the arrow A about the axis AX. (See FIG. 7(B) and FIG. 12). As a result, as shown in FIG. 7A, the first link 102 is displaced in the arrow A direction around the axis AX against the biasing force of the torsion spring 110 . As a result, the guided portion 124 attached to the tip of the second link 106 moves from the base portion 98A of the cam groove 98 to the base portion 98B against the biasing force of the torsion spring 110 .

Here, when the pushing of the glove box 12 toward the front side of the vehicle is stopped, as shown in FIG. It is As a result, the guided portion 124 connected to the first link 102 via the second link 106 reaches the bottom portion 98D from the base portion 98B of the cam groove 98 through the first groove portion 98C. Since the biasing force of the torsion spring 110 is in the direction of the arrow B around the axis AX, the guided portion 124 does not enter the second groove portion 98E.

Along with this movement of the guided portion 124, the lifter 16 connected to the guided portion 124 via the second link 106 and the first link 102 rotates about the axis AX in the direction of arrow B (FIG. 8B). )reference). As a result, as shown in FIG. 13, the engaging convex portion 76 of the lifter 16 positioned at the radial portion 34 of the engaging hole portion 30 of the glove box 12 moves to the circumferential portion 32 (open position).

As a result, the glove box 12 becomes freely openable (openable) around the shaft portion 28, and is opened by its own weight as shown in FIG.

Next, the closing operation of the glove box 12 will be described.

The opened glove box 12 is pushed to a second push-in position on the front side (back side) of the vehicle from the closed position.

At this time, when the glove box 12 returns to the closed position, the vehicle rear side end of the circumferential portion 32 of the engagement hole 30 of the glove box 12 abuts the engagement projection 76 of the lifter 16, and the engagement projection 76 is pushed forward of the vehicle (see FIG. 13).

As a result, the lifter 16 is urged in the arrow A direction around the axis AX. 9A, the guided portion 124 connected to the lifter 16 via the first link 102 and the second link 106 moves toward the cam groove 98 against the biasing force of the torsion spring 110. As shown in FIG. from the bottom portion 98D of the second groove portion 98E to reach the main portion 98F1 of the third groove portion 98F.

As the guided portion 124 moves in the cam groove 98 in this way, the lifter 16 connected to the guided portion 124 via the second link 106 and the first link 102 rotates in the direction of arrow A (FIG. 9). (B)), and the engaging protrusion 76 is caused to enter the radial portion 34 of the engaging hole 30 of the glove box 12 (see FIG. 15).

Here, when the pushing of the glove box 12 toward the vehicle front side is stopped, the first link 102 is rotated (biased) in the arrow B direction around the axis AX by the biasing force of the torsion spring 110 .

As a result, the guided portion 124, which is connected to the first link 102 via the second link 106, is biased in the direction of the arrow B about the axis AX, and the body portion 98F1 of the third groove portion 98F of the cam groove 98 ( (guided by the step 142C) moves to the platform 98A. At this time, due to the step 142C, the guided portion 124 does not move from (the body portion 98F1 of) the third groove portion 98F to the second groove portion 98E.

Due to this movement of the guided portion 124, the lifter 16 rotates about the axis AX in the direction of the arrow B (see FIG. 6B), and the engagement hole portion 30 into which the engagement convex portion 76 of the lifter 16 is inserted is opened. The glove box 12 is returned to the closed position (restored to the closed (locked) state) (see FIG. 11).

When closing the glove box 12 from the open state, as shown in FIG. 16, if the glove box 12 is excessively pushed forward of the vehicle from the second pushing position, the lifter 16 moves around the axis line AX. direction (see FIG. 10B), and the guided portion 124 moves around the axis AX in the direction of arrow A, that is, to the extended portion 98F2 of the third groove portion 98F (see FIG. 10A).

Here, when the pushing of the glove box 12 is stopped, the biasing force of the torsion spring 110 causes the first link 102 to rotate about the axis AX in the arrow B direction. The guided portion 124 is also biased in the direction of the arrow B around the axis AX and guided by the partition wall 136 to move from the extension portion 98F2 of the third groove portion 98F to the main body portion 98F1 and then to the upper base portion 98A. . At this time, since the extended portion 98F2 of the third groove portion 98F is surrounded by the peripheral wall 132 and the partition wall 136 of the cam groove portion 140, the guided portion 124 can move from the extended portion 98F2 of the third groove portion 98F to the base portion 98B. prevented.

That is, when closing the glove box 12 from the open state, even if the glove box 12 is excessively pushed forward of the vehicle from the second pushing position, the glove box 12 is prevented from being opened again, and the glove box 12 is securely closed. closed (locked).

(effect)
Thus, in the glove box opening/closing mechanism 10 according to one embodiment, only the push lifter mechanism 100 is provided on the side plate 14 that supports the glove box 12 (only the engagement hole 30 is provided on the glove box 12 side). ), the glove box 12 can be opened and closed.

In other words, the push-open glove box opening/closing mechanism 10 can be configured only by attaching the lock case 18 including the lifter 16 in which the push lifter mechanism 100 is housed to the side plate 14 .

Therefore, since the opening/closing mechanism 10 of the glove box does not require much space, it is possible to secure a sufficient capacity of the glove box 12 while preventing an increase in the size of the glove box as a whole.

In particular, since the glove box 12 is a push-open type (a type that opens and closes the glove box 12 by pushing the glove box 12), it is necessary to provide a lever or the like on the lid (rear plate portion 26) to open the glove box 12. Therefore, the capacity of the glove box 12 can be sufficiently secured.

Further, the push lifter mechanism 100 includes a part of the shaft portion 60 of the lifter 16, a first link 102, a second link 106, and a torsion spring 110 arranged inside the lock case 18, and a bottom wall of the case main body 80. A cam groove portion 140 (cam groove 98 ) is formed in 84 . That is, the push-lifter mechanism 100 can achieve push-open/push-close of the glove box 12 with a very compact configuration.

That is, a sufficient capacity can be ensured while suppressing an increase in size of the glove box 12 .

In the cam groove portion 140 of the push lifter mechanism 100, the body portion 98F1 of the third groove portion 98F of the cam groove 98 communicates with the second groove portion 98E and the base portion 98A, and the extension portion 98F2 of the third groove portion 98F is the cam groove portion. It is surrounded by the peripheral wall 132 of 140 and the partition wall 136 and isolated from the base portion 98B. As a result, when the glove box 12 is pushed in, even if the glove box 12 is excessively pushed forward of the vehicle from the second pushed-in position, the guided portion 124 only moves from the main body portion 98F1 of the third groove portion 98F of the cam groove 98 to the extension portion 98F2. , the third groove portion 98F (the extension portion 98F2 thereof) does not move to another place, for example, the base portion 98B. In other words, even if the glove box 12 is excessively pushed further (to the excessively pushed position) than the second pushed position, for example, the guided portion 124 moves from the base portion 98B to the first groove portion 98C and the glove box 12 is opened again. is reliably prevented.

(others)
The first pushed-in position and the second pushed-in position of the glove box 12 described in this embodiment may be the same or different.

Further, in the present embodiment, the engaging convex portion 76 inserted into the engaging hole portion 30 of the glove box 12 is a part of the lifter 16 of the push lifter mechanism 100 , and the lifter 16 is biased by the torsion spring 110 . Although the configuration is such that the lock is released by resisting and rotating, the present invention is not limited to this.

That is, by providing an engagement convex portion 76 perpendicular to the axial direction of the rod at the tip of the rod that advances and retreats with respect to the cylinder, and controlling the advance and retreat of the rod with a knock cam mechanism provided inside the cylinder, the same as in the above embodiment. In addition to locking and unlocking the glove box 12, the cam shape of the knock cam mechanism is devised so that the glove box 12 is not opened again even if the glove box 12 is pushed excessively when closing. can.

In this case, the cam of the knock cam mechanism corresponds to the "locking mechanism" and the "blocking mechanism".
