Description

Vehicle storage device

The present disclosure relates to a storage device for a vehicle.

As a vehicle storage device, there is a glove box installed at the lower part of the passenger seat side of the instrument panel of an automobile. As the glove box, an integral type and a lid type are generally adopted. The integrated glove box opens and closes an opening provided in an instrument panel by rotating a glove box body that accommodates an article. The lid-type glove box opens and closes the opening of the glove box body that is mounted on the instrument panel as the lid rotates. When applying a damping device to open and close the glove box, it is common to use an air damper in the integrated glove box, but in the lid type glove box, the movable part is lighter than the integrated glove box, so comparison Even with an inexpensive rotary damper, a sufficient damping effect can be obtained (for example, Patent Document 1).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a vehicle 2 in which a vehicle storage device 1 according to the embodiment is installed. Note that the vertical direction, the horizontal direction, and the front-rear direction in the description follow the direction of the vehicle 2. The storage device 1 is a glove box installed on the instrument panel 3 of the vehicle 2. The storage device 1 includes a storage device body 4 that is fixed to the instrument panel 3 and stores articles, and a lid 6 that opens and closes an opening 5 of the storage device body 4. FIG. 1 shows the lid 6 in a closed position with the opening 5 closed. The lid 6 is pivotally supported by the storage device main body 4 along an axis that is disposed on the lower end side and extends in the left-right direction.

The lid 6 is releasably locked in the closed position by a lock mechanism using a known urging means. When the user pulls the lever 7 provided on the lid 6 against the urging force of the urging means, the lock is released, and the upper end side of the lid 6 is stored in the storage device by gravity or a force applied by the user. It tilts around the axis so as to be separated from the main body 4 and opens to the fully open position.

2 and 3, the storage device 1 includes a lid arm 9 having a gear 8 and a damper unit 10 that meshes with the gear 8 of the lid arm 9 in order to attenuate the opening / closing speed of the lid 6. One set of the lid arm 9 and the damper unit 10 is preferably provided on the left and right sides of the lid 6. Since the left and right lid arms 9 and the damper unit 10 are substantially symmetrical with each other, a description will be given below of an example provided on the left side.

The lid arm 9 is fixed to the left side of the lid 6 on the rear end side and at a position away from the tilting axis of the lid 6. The lid arm 9 extends in a shape along the tilting direction of the lid 6, that is, in an arc shape. The lid arm 9 is made of resin or the like, and has a flat main plate 11 whose main surface faces in the left-right direction, an upper rib 12a formed to extend to the left along the upper end and the lower end of the main plate 11, and And a lower rib 12b. A stopper 13 that defines the fully open position of the lid 6 is formed on the front end side of the lid arm 9 by extending upward from the upper rib 12 a and being locked to the storage device body 4.

As shown in FIGS. 4 and 5, the damper unit 10 holds the lid arm 9 movably in the movement direction of the lid 6 and engages the damper holder 14 that engages with the storage device body 4 and the gear 8 of the lid arm 9. And a rotating damper 15 that is engaged with and held by the damper holder 14.

The damper holder 14 is made of resin or the like, and includes a pair of sandwiching pieces 16 that sandwich the lid arm 9 from the left and right directions, and a connecting portion 17 that connects the upper ends of the pair of sandwiching pieces 16 to each other in the front-rear direction. It is generally U-shaped in a cross-sectional view orthogonal to. The connecting part 17 shown in the figure is divided into two parts, a first connecting part 17a on the rear and a second connecting part 17b on the front, but it may be divided into one or three or more. The connecting portion 17 may be provided on the lower end side of the pair of sandwiching pieces 16.

The right holding piece 16a is formed with a cylindrical or columnar boss 20 which is received in a recess 19 formed by a wall 18 protruding leftward from the side surface of the storage device body 4. Since the boss 20 is loosely fitted into the recess 19 and is pivotally supported, the damper holder 14 is allowed to rotate about the left-right axis, and the boss 20 is displaced in a plane perpendicular to the left-right direction with respect to the storage device body 4. Is allowed within a predetermined range. The recess 19 is formed in the vicinity of the movement path of the gear 8 on the side surface of the storage device body 4. The concave portion 19 preferably has an oval shape in a side view, the major axis direction thereof is 90 ° or an angle close to 90 ° with respect to the moving direction of the lid arm 9, and the inner diameter of the concave portion 19 in the minor axis direction Coincides with the outer diameter of the boss 20, whereby the displacement of the boss 20 in the moving direction of the lid arm 9 relative to the storage device body 4 is restricted. The movement of the boss 20 in the direction perpendicular to the movement direction of the lid arm 9 relative to the storage device body 4 (normal direction of the movement direction of the lid arm 9 in the plane perpendicular to the left-right direction) is allowed within a predetermined range. Therefore, the angle can be changed in a range larger than 0 ° and smaller than 180 °. Moreover, it is preferable that the wall 18 forming the recess 19 is provided with a reinforcing wall 18a extending in the front-rear direction or the moving direction of the lid arm 9 and downward.

The left clamping piece 16b is provided with a fixing hole 22 for fitting and fixing the housing 21 of the rotary damper 15. The fixing hole 22 is formed so that the rotation axis of the rotary damper 15 is coaxial with the boss 20. The wall 23 that forms the fixing hole 22 extends in the left-right direction, and a part of the lower lower surface thereof constitutes a guide portion 25 that is in sliding contact with a smooth guided surface 24 formed on the upper surface of the lower rib 12b. ing. The guide portion 25 has an arc shape centered on the rotation axis of the rotary damper 15 in a side view, and the curvature radius thereof is smaller than the curvature radius of the guided surface 24. Rollable within a predetermined range. The rollable range is defined by the position where the connecting portion 17 is locked to the upper rib 12a.

The rotation shaft of the rotary damper 15 is provided with a pinion 26 that meshes with the gear 8. The pinion 26 can rotate around the rotation axis with respect to the housing 21, and rotates by receiving resistance due to the viscosity of the oil in the housing 21. When the lid arm 9 moves relative to the damper unit 10 along the tilting direction of the lid 6, when the pinion 26 meshed with the gear 8 rotates with respect to the housing 21 and the damper holder 14, the opening / closing speed of the lid 6 is attenuated. . However, when the housing 21 and the damper holder 14 rotate together with the pinion 26, no damping force is generated and the opening / closing speed of the lid 6 is not attenuated.

In the left-right direction, the pair of sandwiching pieces 16 sandwich the lower rib 12b of the lid arm 9, and the pinion 26 meshes with the gear 8 from below in the direction normal to the moving direction of the lid arm 9 in a plane orthogonal to the rotation axis. Since the guide portion 25 is in sliding contact with the guided surface from above, the lid arm 9 is held by the damper unit 10 so as to be movable only in the tilting direction of the lid 6 with respect to the damper unit 10.

The distance from the rotation axis of the pinion 26 to the connecting portion 17 is slightly longer than the distance from the rotation axis of the pinion 26 to the smooth sliding contact surface 27 formed on the upper surface of the upper rib 12a. Due to the difference in distance and the fact that the guide portion 25 has an arc shape centered on the rotation axis of the rotary damper 15, the damper unit 10 is located with respect to the lid arm 9 about the rotation axis of the rotary damper 15. Can be tilted. This tilting range is defined by the sliding contact portion 28 formed in the connection portion 17 coming into contact with the sliding contact surface 27. The slidable contact portion 28 is formed so that the first slidable contact portion 28a constituting the rear edge of the lower surface of the first connecting portion 17a and the rear edge of the second connected portion 17b are slightly protruded downward. It consists of two parts 28b (see FIG. 6). When one of the first sliding contact portion 28 a and the second sliding contact portion 28 b is in contact with the sliding contact surface 27, the other is disposed so as to be separated from the sliding contact surface 27.

Next, with reference to FIG.3 and FIG.6, the effect at the time of opening and closing of the lid 6 of the storage apparatus 1 which concerns on embodiment is demonstrated.

FIG. 6A shows the periphery of the damper unit 10 when the lid 6 is in the closed position. When the lid 6 is moved in the closing direction, the second sliding contact portion 28b slides on the sliding contact surface 27 as described later. Even after the lid 6 reaches the closed position, the damper holder 14 is maintained in a state in which the second sliding contact portion 28b is in contact with the sliding contact surface 27 by the frictional force between the rotating shaft of the rotary damper 15 and the housing 21. Yes.

When the user pulls the lever 7 (see FIG. 1) and the lid 6 slightly moves in the opening direction by the force or gravity applied by the user, the state shown in FIG. 6B is obtained. At this time, since the lid arm 9 moves in the movement direction of the lid 6 with respect to the damper unit 10, the pinion 26 meshed with the gear 8 rotates. Due to the viscous resistance between the rotating shaft of the rotary damper 15 and the housing 21, the damper 21 that fixes the housing 21 and the housing 21 is rotated following the pinion 26. Accordingly, the damper unit 10 tilts until the second sliding contact portion 28 b is separated from the sliding contact surface 27 and the first sliding contact portion 28 a contacts the sliding contact surface 27. In this section, the lid 6 and the lid arm 9 do not receive the damping force of the rotary damper 15.

From the position shown in FIG. 6B to the fully open position, the first slidable contact portion 28 a is in sliding contact with the slidable contact surface 27, so that the tilt of the damper holder 14 is restricted, so that the pinion 26 includes the housing 21 and the damper holder 14. Rotate against. Therefore, the lid 6 and the lid arm 9 are subjected to the damping force of the rotary damper 15.

As described above, since the damping force does not work at the initial stage of the opening operation of the lid 6, the user does not need to apply a large force when opening the lid 6, and the operability is good. Moreover, if the position of FIG. 6B is set to a position where the lock of the lid 6 does not return even if the user releases the lever 7 (see FIG. 1), the risk of unlocking failure is reduced. Can do.

After that, the lid 6 is opened to the fully open position where the stopper 13 is locked to the locking portion 29 of the storage device body 4 by gravity or a force applied by the user. When the lid 6 is returned from the fully open position to the closed position, the housing 21 is moved until the first sliding contact portion 28a is separated from the sliding contact surface 27 and the second sliding contact portion 28b is locked to the sliding contact surface 27. Since the damper holder 14 rotates following the pinion 26, the lid 6 and the lid arm 9 do not receive the damping force of the rotary damper 15. Therefore, in the initial stage of the closing operation, the user does not need to apply a large force, so that the operability is good.

Further, due to manufacturing errors and assembly errors of the members, the boss 20 is loosened in the concave portion 19 even if the moving direction of the lid 6 does not completely coincide with the extending directions of the sliding contact surface 27, the gear 8, and the guided surface 24. Because of the fitting, the damper unit 10 holding the lid arm 9 moves in a plane orthogonal to the rotation axis, and the deviation is corrected. Therefore, it is possible to prevent unintended resistance between the lid arm 9 and the damper unit 10, tooth skipping, abnormal noise, and the like. In particular, when the concave portion 19 has an oval shape in which the major axis direction is in a normal direction with respect to the moving direction of the lid arm 9 and the inner diameter in the minor axis direction matches the outer diameter of the boss 20 in a side view, Since the displacement in the moving direction of 9 is restricted and only the displacement in the direction perpendicular thereto is allowed, the structure of the recess 19 and the movable range of the damper unit 10 can be saved. Further, since the damper unit 10 holds the lid arm 9 and is loosely supported by the storage device body 4, the damper unit 10 is hardly affected by the rigidity of the lid arm 9.

Moreover, since the lid arm 9 can be assembled to the storage device body 4 by inserting the boss 20 into the recess 19 in a state where the damper unit 10 is assembled to the lid arm 9, the assembly is easy. In addition, when the connection part 17 which connects a pair of clamping pieces 16 is arrange | positioned below rather than upwards and the sliding contact surface 27 is formed so that it may form in the lower surface of the lower rib 12b, the damper unit 10 is accommodated. After assembling to the main body 4, the lid arm 9 can also be assembled by being inserted into the damper unit 10 from the front end side. This is because the stopper 13 protruding upward in the lid arm 9 can pass the free end side of the pair of clamping pieces 16.

This is the end of the description of the specific embodiment, but the present invention is not limited to the above-described embodiment, and can be widely modified. Only one sliding contact portion is provided, and at the initial stage of the opening operation and the closing operation, that one sliding contact portion is separated from a certain point of the sliding contact surface by tilting of the damper holder and then locked to another point on the sliding contact surface. In the subsequent opening operation and closing operation, the sliding contact surface may be slidably contacted. Further, the recess may be formed by recessing a part of the side wall of the storage device body, or may be changed to a hole.
