Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a locking mechanism for a vehicle lid that closes an opening of a storage container such as a glove box provided in a vehicle body.

[Prior Art] Conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 57-97738, a lid has been installed in a storage container such as a glove box provided in an instrument panel. Furthermore, in order to facilitate the opening operation of the lid, a push-open type locking device is provided, and by pushing the lid, the locked state of the lid can be released. ing.

[Problem to be solved by the invention] In the locking mechanism of a vehicle lid equipped with the push-open type locking device described above, when a collision load is applied during a vehicle collision, an inertia force corresponding to the own weight of the lid is generated. Therefore, this inertial force may cause a malfunction in which the lid is unlocked.

The present invention solves the above-mentioned problems of the prior art, and provides a vehicle lid that can reliably prevent malfunctions in which the lid is unlocked due to inertial force that acts during a collision. It is intended to provide a locking mechanism.

[Means for Solving the Problems] The present invention includes a storage container attached to the vehicle body, a lid installed in the opening of the storage container so as to be openable and closable, and a push-open type that holds the lid in a closed state. The locking device is equipped with a regulating means for regulating the movement of the lid in the unlocking direction of the locking device when an impact load is applied to the vehicle body.

[Function] According to the above structure, when an impact load is applied to the vehicle body during a collision, the movement of the lid is restricted by the restriction means, thereby preventing the locking device from being released from the locked state.

[Embodiment] FIGS. 1 and 2 show a locking mechanism for a vehicle lid according to a first embodiment of the present invention. This locking mechanism is connected to a storage container 3 installed in an instrument panel 2 located above a console 1.
, a lid 5 that is supported so as to be openable and closable via a pair of hinge brackets 4 provided at the upper side of the opening of the storage container 3, and a push-open type lock that holds the lid 5 in a closed state. When an impact load is applied to the device 6 and the vehicle body, the lid 5 comes into contact with the back surface of the lid 5 and locks into the locking device 6.
A regulating member 7 for regulating movement in the unlocking direction.

The locking device 6 is located at a position facing the engagement pin 8 protruding from the back side of the lid 5.
It is attached to the mounting flange portion 9 of the storage container 3, and by pushing and operating it with the lid 5 closed, the engagement pin 8 is sequentially changed between a state in which it is held and a state in which it is released. Since its specific structure is conventionally well known, its explanation will be omitted.

As shown in FIG.
1, a stopper 15 supported in a cylindrical body 14 formed at the upper part of the case 11 and the lid 12 so as to be movable up and down; It includes a compression spring 17 that is fitted onto the front end shaft portion 16 and a compression spring 18 that is fitted onto the center of the stopper 15 . As shown in FIG. 1, the weight member 13 is biased rearward by a compression spring 17 so that its rear end comes into contact with the rear wall surface of the case 11, and the bulge 19 formed on the rear upper surface is pressed against the stopper. It is installed at the rear side of 15. Further, the stopper 15 is biased upward by the compression spring 18 so that the flange 20 formed on the upper part comes into contact with the upper wall surface of the cylinder 14, and the upper end part is placed above the mounting flange part 9 of the storage container 3. It protrudes and is installed with a predetermined gap between the lower end and the weight member 13.

As described above, in the normal state, a predetermined gap is formed between the lower end of the stopper 15 of the regulating member 7 and the weight member 13, so as shown in FIG. The engaging pin 8 and the stopper 15 can be lowered in the direction shown by the arrow by pushing the lever, thereby releasing the holding state of the engaging pin 8 by the locking device 6 and opening the lid 5. Can be done. When an impact load is applied to the vehicle body due to a head-on collision, etc., an inertia force corresponding to the own weight of the lid 5 acts on the front side of the vehicle body, causing the lower end of the lid 5 to move forward. At the same time, as shown in FIG. 5, the weight member 13 moves forward due to inertial force against the bias of the compression spring 17, and the bulge portion 19 of the weight member 13 is located below the stopper 15. The engagement pin 8 and stopper 15 are prevented from descending. Therefore, when the impact load is applied, the holding state of the engagement pin 8 by the locking device 6 is prevented from being released, and the locked state of the lid 5 can be maintained.

Furthermore, in the above embodiment, since the rear end of the weight member 13 is installed in contact with the rear wall surface of the case 11, when an inertial force acts on the rear side of the vehicle body due to a rear-end collision, etc. After the rear end portion of the weight member 13 is pressed against the rear wall surface of the case 11, the weight member 13 moves forward due to the reaction. As a result, there is an advantage in that it is possible to prevent the lower end of the lid 5 from moving forward due to the reaction of the inertial force acting on the lid 5, thereby preventing the lid 5 from being released from the locked state.

FIGS. 6 and 7 show a locking mechanism according to a second embodiment of the present invention, in which the instrument panel 2
There is a lid 5 at the opening of the storage container 3a installed in the
a is rotatably supported via a hinge bracket 14 located at the lower end. A regulating member 7a is installed on the upper wall of the storage container 3a, and a push-open type locking device 6 is installed on the mounting flange 9a of the storage container 3a.

As shown in FIG.
A weight member 21 rotatably supported around a support pin 20 protruding inside, and this weight member 2
1 is provided with a tension spring 22 that urges the lid 5a to a pushing allowable position, which will be described later. The weight member 21 has a stopper portion 23 that protrudes outward from the case 11a, and in a normal state, as shown in FIG. 9, the weight member 21 is
The base end 24 of the lid 5a comes into contact with a locking protrusion 25 protruding from the case 11a, and the stopper portion 23 is locked in a state located outside the side end of the lid 5a. It is configured to allow a pushing operation of 5a.

When an inertial force or a reaction force is generated according to the impact load that acts upon a frontal collision or rear-end collision of a vehicle, as shown in FIG. 10, the weight member 2
1 resists the biasing force of the tension spring 22 and the support pin 2
0 in the counterclockwise direction in the drawing, the base end 24 of the weight member 21 moves toward the front side of the vehicle body, and the tip of the stopper part 23 is positioned inside the side end of the lid 5a. It's getting old. Therefore, in the event of a vehicle collision, the upper end of the lid 5a is prevented from moving forward due to inertia generated in the lid 5a, and the locking device 6 prevents the lid 5a from moving forward.
It is possible to prevent the locked state of a from being released.

FIGS. 11 and 12 show a locking mechanism according to a third embodiment of the present invention, which is constructed in the same manner as the first embodiment except for the structure of the regulating member 7c. As shown in FIG. 13, the regulating member 7c includes a case 11c and a lid body 12c.
and a weight member 27 rotatably supported around a support pin 26 protruding from the case 11c.
A tension spring 28 is provided to urge the weight member 27 to a position where the lid 5 is allowed to be pushed. In a normal state, as shown in FIG. 11, the upper end of the weight member 27 comes into contact with the locking part 29 formed on the upper part of the case 11c and connects with the upper end surface of the mounting flange part 9 of the storage container 3. locked in approximately the same position,
Push operation of the lid 5 is permitted.

When an inertial force or a reaction force is generated during a vehicle collision, the weight member 27 rotates clockwise in the drawing about the support pin 26 against the biasing force of the tension spring 28, as shown in FIG. The upper end of the member 27 moves toward the rear of the vehicle body and projects above the mounting flange 9 of the storage container 3, thereby preventing the lower end of the lid 5 from moving forward. Therefore, it is possible to prevent the lid 5 from being unlocked due to inertia generated during a vehicle collision.

In each of the above embodiments, the weight members 13, 21, 27 are displaced to the movement restriction position of the lids 5, 5a by the inertia force generated at the time of a vehicle collision, and the weight members 13, 21, 27 are moved indirectly or The lids 5, 5a are configured to be in direct contact with the back surfaces of the lids 5, 5a to prevent them from moving in the unlocking direction of the locking device, but the lids 5, 5a are restrained from moving in the unlocking direction of the locking device. A structure may also be provided in which a driving means is provided for detecting the stopper member by, for example, a detection signal, and moving the stopper member to the movement restriction position of the lid 5 in response to the detection signal.

[Effects of the invention] As explained above, the present invention allows the lid provided at the opening of the storage container to move in the unlocking direction of the push-open type locking device when an impact load is applied to the vehicle. Since a regulating member is provided to restrict the movement of the lid, even if an inertia force corresponding to the lid's own weight is generated in response to the above-mentioned impact load, the movement of the lid is prevented and the locking state of the lid by the locking device is released, which is a malfunction. can be reliably prevented from occurring.
