Description

  The present invention relates to a storage box for a vehicle, and more particularly to an improvement in a lock structure of a lid of the storage box.

  As a vehicle storage box, for example, a glove box (an example of a vehicle storage box) capable of storing small items such as vehicle verification may be provided in the vehicle interior. An openable / closable lid (lid) is provided to cover the opening of the box body so that the stored items do not accidentally jump out of the box.

  In general, the lid is urged in the opening direction by the action of gravity, a spring or the like in consideration of the convenience of the user.

  For this reason, a lock structure is provided between the lid, the box body, the dashboard, and the like in order to keep the lid closed when it is not necessary. Specifically, a striker (an example of an engaged portion) is fixed to the box body, the dashboard, and the like, and the lid is engaged with the striker (engagement position) and the engagement is released. An operation portion such as a knob for moving the lock claw from the engagement position to the engagement release position is provided.

  When the lid is closed, a user such as an occupant moves the lock claw from the engagement position to the disengagement position by operating the operation unit, so that the lock claw is detached from the striker and the lid is attached. It is designed to open by power.

  In addition, the lock claw itself or the operation part for interlocking the lock claw is also urged to the engagement position side in the movable range, so that the lock claw is inadvertently moved without being operated. It is prevented from coming off the striker (Patent Document 1).

  For example, in the vehicle storage box 100 shown in the cross-sectional view of FIG. 6, the flip-up type lid 110 that covers the opening of the storage box main body 190 is opened from the closed state indicated by the solid line to the two-dot chain line. In addition, the storage space 180 inside the storage box main body 190 can be accessed by rotating in the counterclockwise direction R1 shown in the figure about the rotation center C1 positioned above the striker 130. .

  Here, the lid 110 is provided with an operation unit 120 that is integrally formed with a lock claw 122 and a finger hook 121 on which a user's finger 200 is hung, and is rotatable about a rotation center C2. The operation unit 120 is biased in the clockwise direction (the direction opposite to the arrow R2 direction; the flip-up direction) by a biasing means such as a spring (not shown).

  The lid 110 itself is also urged in the arrow R1 direction by an urging means such as a spring (not shown).

In a state where the lid 110 is closed (solid line position in the drawing), the lock claw 122 of the lid 110 is engaged with the striker 130 fixed to the storage box main body 190 from below (engagement position), and the lid 110 is engaged. Is prevented from rotating in the opening direction, and the lid 110 is kept closed. When an operation force in the clockwise direction is applied, the lock claw 122 integrated with the finger hook portion 121 also rotates in the arrow R2 direction to disengage from the striker 130 (disengagement position), thereby the lid 110 Becomes free, and is rotated in the direction of opening around the rotation center C1 by the applied urging force to be in an open state (the two-dot chain line position in the figure).
Japanese Patent No. 2989804

  By the way, in the above-described vehicle storage box, for example, as shown in FIG. 7, when a large load F is input downward or obliquely forward and downward, the lid 110 is illustrated from a normal state (state of the two-dot chain line in the figure). The state of the solid line is displaced downward or obliquely forward and downward, for example, with deformation, whereby the lock claw 122 of the lid 110 and the striker 130 are disengaged, and the lid 110 enters an unexpected open state. there is a possibility.

  When such an unexpected open state of the lid 110 occurs, there is a risk that the stored items stored in the storage space 180 of the storage box body 190 may unexpectedly jump out or fall into the vehicle interior.

  Note that the above-mentioned unexpected open state of the lid does not occur only in the storage box having the flip-up type lid as shown in the figure, but even if the lid has a lid that is pulled down toward the front, The striker and the striker can be engaged in the same manner even if the engagement is in the direction released by the load F in the downward direction or the obliquely forward downward direction that is input to the lid.

  This invention is made | formed in view of the said situation, Comprising: Even if a load inputs into a lid, it aims at providing the storage box for vehicles which can maintain a lid in the closed state.

  In the vehicle storage box according to the present invention, the lock claw provided on the lid is displaced between the engagement position where the lock claw is engaged with the engaged portion and the engagement release position where the engagement is released. In the structure, when the load is input to the lid, the displacement direction from the engagement position to the engagement release position is set to be opposite to the input direction of the load input to the lid. Also, the lid is maintained in a closed state.

That is, the vehicle storage box according to the present invention includes a storage box body in which a storage space is formed, a lid that opens and closes an opening for accessing the storage space, and a lock that maintains the lid in a closed state. And the locking mechanism is provided between the engaged portion and an engagement position that is provided on the lid and is engaged with the engaged portion, and an engagement release position that releases the engagement. The lock claw has a displacement, and the lock claw has a displacement direction from the engagement position toward the engagement release position opposite to the input direction of the load input to the lid in the downward direction or the diagonally forward downward direction. An operation for displacing the lock claw from the engagement position to the disengagement position is input when the engagement position of the lock claw is located below the disengagement position. The operation unit Formed physically to constitute a push button, the push button has a hollow box shape, both side walls thereof are provided with outwardly protruding shaft portions, and the lid has the edge portion Enclosures that surround the push buttons are formed, and both side walls of the enclosures are fitted to the shafts of the push buttons so as to displace the push buttons between the engagement position and the engagement release position. A long hole is formed, and an elastic member for urging the push button to the engagement position is disposed between the push button and the upper wall of the enclosure member. A notch extending in the vertical direction is formed in the wall portion between

  According to the vehicle storage box according to the present invention configured as described above, even if a large load is input to the lid in the downward direction or the diagonally forward and downward direction, the lock provided on the lid is provided. Since the claw is set to the disengagement position opposite to the load input direction from the engagement position, even if the lid is displaced downward or diagonally forward and downward, the lock claw There is no displacement to the disengagement position, and therefore the engagement between the lock claw and the engaged portion is maintained, and the lid can be maintained in the closed state.

According to the vehicle storage box of the present invention, since the displacement direction of the lock claw is set between the operation portion and the lock claw without using the intermediate interposition member, the component by adding the intermediate interposition member An increase in the score can be prevented.

According to the vehicle storage box of the present invention, when a load directed downward or diagonally forward and downward is input to the lid, the lid is displaced downward or diagonally forward and downward. At this time, the lock claw provided on the lid is also displaced downward or diagonally forward and downward, but the lock claw disengagement position is set above the engagement position. Therefore, the displacement direction of the lock claw is opposite to the disengagement direction, and the lock claw can be reliably prevented from coming off the striker.

  Therefore, it is possible to reliably prevent the lid from being opened due to the lock claw being disengaged from the engaged portion.

  According to the vehicle storage box of the present invention, the lid can be kept closed even when a load is input to the lid.

  Hereinafter, the best embodiment of a storage box for a vehicle according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a lid (lid) 110 of a glove box (vehicle storage box) 100 according to an embodiment of the present invention and a lock claw 142 that keeps the lid 110 closed, and FIG. FIG. 3 is a cross-sectional view showing the glove box 100 including the lid 110 shown in FIG. 1, and FIG. 3 is an enlarged view showing details of the locking mechanism in FIG.

  As shown in FIG. 2, the illustrated glove box 100 closes the opening communicating with the storage space 180 inside the glove box main body 190 by a solid line 110 covering the opening, while the lid 110 is a side plate piece. The storage space 180 can be accessed by opening the opening in a state (indicated by a two-dot chain line in the figure) rotated in the counterclockwise direction R1 shown in the figure around the rotation center C1 formed in FIG.

  The lid 110 is urged in the opening direction by an urging means (not shown) such as a spring or a damper.

  The lid 110 is integrally formed with a lock claw 142 and a finger pressing portion 141 (operation portion) to which a pressing force in the direction of arrow V is input by a finger 200 (see FIG. 3) of a user such as a vehicle occupant. A push button 140 is provided.

  As shown in FIG. 1, the push button 140 generally has a hollow box shape whose upper end wall is omitted, and shafts 143 and 143 projecting from both side walls are formed at the lower part of the lid 110. It is supported by the enclosure portion 112 in a state of entering the long holes 114, 114 of the enclosure portion 112.

  Since the long hole 114 of the enclosure 112 extends along the arrow V direction described above, the push button 140 can move up and down along the arrow V direction as a whole.

  In addition, two string-wound springs 145 and 145 that extend and contract along the direction of arrow V are disposed inside the hollow of the push button 140, and the lower ends of these string-wound springs 145 and 145 are the lower wall of the push button 140. The upper ends of the string springs 145 and 145 are in contact with the inner surface of the upper wall of the enclosure 112.

  Thus, the push button 140 is urged downward by the elastic force of the string springs 145 and 145.

  In addition, since the two button springs 145 and 145 are disposed along the axis C3 on the push button 140, the vertical direction along the longitudinal direction (direction along the axis C3) of the push button 140 is increased. The distribution of the urging force in the direction can be equalized, and when the push button 140 is pressed, the push button 140 can be prevented from being tilted and moved up and down.

  Further, the wall surface of the push button 140 facing the lid 110 is formed with a notch 141a extending in the vertical direction as shown by a two-dot chain line in FIG. 1B. In the state before assembly shown by the solid line in b), the distance between the two shaft portions 143 and 143 can be reduced by elastically deforming the notch 141a so as to close the two shafts. The parts 143 and 143 are inserted between the long holes 114 and 114 of the enclosure part 112 set at substantially the same distance as the distance between the shaft parts 143 and 143 in the natural state before the notch 141a is closed. The portions 143 and 143 can be inserted into the long holes 114 and 114, respectively, and are opened in a natural state before the notch 141a is closed. Down 140 is supported in the enclosure section 112.

  A lock claw 142 provided on the push button 140 protrudes downward in the figure, and the lock claw 142 is engaged with an engaged hole 191 (engaged portion) formed in the glove box body 190. It is combined, and is displaced between an engagement position engaged with the engaged hole 191 and an engagement release position for releasing the engagement.

  That is, when the shaft portions 143 and 143 of the push button 140 are positioned at the lower ends of the long holes 114 and 114 of the enclosure portion 112 of the lid 110, the lock claw 142 is engaged with the engaged hole 191 from above. Therefore, the engagement position (the position indicated by the solid line in FIG. 3) is obtained, and a pressing force in the direction of arrow V against the urging force of the string springs 145 and 145 is applied to the finger pressing portion 141 of the push button 140. When the shaft portions 143 and 143 of the 140 are displaced in the direction of the arrow V (upward) along the long holes 114 and 114, the lock claw 142 is engaged with the engaged holes when the entire push button 140 is pushed upward. This is the disengagement position (the position of the two-dot chain line in FIG. 3) where the engagement is released from 191 upward.

  That is, the lock claw 142 and the engaged hole 191 constitute a lock mechanism that keeps the lid 110 closed.

  When the lock claw 142 is in the engaged position, the lock claw 142 is engaged with the engaged hole 191, so that the lock mechanism closes the lid 110 against the urging force acting on the lid 110. The state is maintained (the position indicated by the solid line in FIG. 2).

  On the other hand, when the lock claw 142 is in the disengagement position, the lock claw 142 is disengaged from the engaged hole 191, so the lock mechanism does not resist the urging force acting on the lid 110, and the lid 110 Is in an open state (the position of the two-dot chain line in FIG. 2).

  That is, the lock claw 142 is set such that the displacement direction from the engagement position toward the engagement release position is a direction (upward) along the arrow V direction.

  Here, for example, as shown in FIG. 4, a large load may be input to the lid 110 in the direction of arrow F (downward in the figure or diagonally forward downward) by an occupant or the like in the vehicle compartment.

  In this case, the lid 110 is displaced from the normal state (the state of the two-dot chain line in the drawing) to the state of the solid line in the downward direction or obliquely forward and downward with deformation.

  Here, in the conventional storage box, the lock claw of the lid and the engaged portion such as the striker may be disengaged, and the lid may reach an unexpected open state. 100 indicates that the lock claw 142 provided on the lid 110 is engaged even when a large load is input to the lid 110 in the direction of the arrow F (downward or diagonally forward downward). Since the disengagement position is set from the position in the arrow V direction (upward) that is substantially opposite to the load input direction F, the lid 110 is displaced in the arrow F direction as shown by the solid line in the figure. Even in this case, the lock claw 142 is not displaced to the disengagement position, but rather is displaced in a direction (arrow -V direction) in which the engagement between the lock claw 142 and the engaged hole 191 is further strengthened.

  Therefore, the engagement between the lock claw 142 and the engaged hole 191 is maintained, and the lid 110 can be maintained in the closed state.

  Therefore, the unexpected opening state of the lid 110 can be prevented, and the stored items stored in the storage space 180 of the glove box body 190 can be prevented from unexpectedly jumping out or falling into the vehicle interior. be able to.

  In addition, although this embodiment applies the glove box 100 as a storage box for vehicles, the storage box which concerns on this invention is not limited to the glove box 100 of this embodiment, It is used for a vehicle. As long as it has a function as a storage box, it can be applied to a console box or other storage boxes.

  In addition, about the assumed input load, it can set beforehand experimentally and empirically.

  In the glove box 100 of the present embodiment, the finger pressing portion 141 to which an operation for displacing the lock claw 142 from the engagement position to the engagement release position is formed integrally with the lock claw 142. Since the displacement direction of the lock claw 142 is set between the lock claw 142 and the lock claw 142 without interposing the intermediate interposed member, an increase in the number of parts due to the additional addition of the intermediate interposed member can be prevented.

  The vehicle storage box according to the present invention does not exclude the one that increases the number of parts. For example, as shown in FIG. 5, a finger hook knob 161 that can rotate around the rotation axis C4 is provided as an operation unit. At the same time, a substantially L-shaped lock member 162 formed at one end with a lock claw 162 b that engages with a striker 170 (engaged portion) fixed to the glove box main body 190 is interlocked with the rotation of the finger hook knob 161. It is also possible to adopt a configuration in which an interlocking operation unit 160 is provided so as to rotate around the axis C5.

  Here, when the finger hooking portion 161a of the finger hooking knob 161 is pulled in the direction of the arrow, the finger hooking knob 161 as a whole rotates around the rotation axis C4 counterclockwise in the figure, and the opposite end portion 161b across the rotation shaft C4 is locked. The end 162a of the member 162 is pushed.

  As a result, the lock member 162 as a whole rotates clockwise around the rotation axis C5, the lock claw 162b is displaced upward, is disengaged from the striker 170, and the lid 110 is opened.

  That is, in the glove box 100 of this embodiment, the lock claw 162b is set so that the displacement direction from the engagement position to the engagement release position is substantially upward, and this displacement direction corresponds to the load shown in FIG. Since the direction is substantially opposite to the input direction F, the vehicle storage box according to the embodiment of the present invention has the structural requirements as an embodiment and can prevent the lid 110 from being unexpectedly opened. The stored items stored in the storage space 180 of 190 can be prevented from unexpectedly jumping out or falling into the vehicle interior.

  Further, when a load directed in the direction of arrow F (downward or diagonally forward and downward) is input to the lid 110 of the glove box 100 of each embodiment described above, the lid 110 is moved downward or diagonally forward and downward. The lock claws 142 and 162b provided on the lid 110 are also displaced downward or obliquely forward and downward, but the engagement position of the lock claws 142 and 162b is more than the disengagement position. Since the engagement disengagement position of the lock claws 142 and 162b is set above the engagement position, the displacement direction of the lock claws 142 and 162b is disengaged. The direction is opposite to the direction, and the locking claws 142 and 162b can be reliably prevented from coming off the engaged hole 191 (FIGS. 1 to 4) and the striker 170 (FIG. 5).

  Therefore, it is possible to reliably prevent the lid 110 from being opened due to the lock claws 142 and 162b being disengaged from these engaged portions.
