Abstract

PROBLEM TO BE SOLVED: To prevent the theft of articles stored in a glove box for vehicle, by driving a lock member to a fixation releasing position so as to allow the cover material opening operation at the only time when coming close of an operator to an operation unit or opening operation of a cover material is detected during the time when getting on of a regular occupant is recognized. SOLUTION: In the case where a regular occupant gets off a vehicle in the condition that a cover material is closed, a control device 22 recognizes it, and when a door is locked or an ignition key is drawn out, even in the case where operation of an operation button 17 is detected, the lock member 20 is maintained at a second rotating position. Consequently, an end surface of the operation button 17 abuts on the peripheral surface of the lock member 20 so as to fix a latch member 11 in the condition that the latch member 11 is engaged with a striker. In this condition, even if the operation button 17 is pushed, the cover material can not be opened. During the time when the control device 22 recognizes getting on of the normal occupant, when the operation of the operation button 17 is detected, the lock member 20 is rotated from the second rotating position to the first rotating position and held at the first rotating position so as to allow the operation button 17 to be pushed in.

FIG. 1 is a front view showing the configuration of a dashboard 1 on the front of a vehicle compartment provided with a glove box to which the present invention is applied. A handlebar 2 and the like are provided on the driver's seat side on the left side with respect to the paper surface, and a glove box is provided on a lower front part on the right passenger's seat side via a central portion 3 provided with a radio, an operation panel of an air conditioner, and the like. 4 are provided. In the opening of the glove box 4, a lid 5 having a hinge at a lower portion thereof is provided so as to be openable and closable. A U-shaped striker 6 is provided at the upper center of the opening of the glove box 4. A latch member 11 of a latch mechanism 8 described later is provided at a position corresponding to the striker 6 on the lid 5 side. Further, an operation section 7 is provided at a position on the lid 5 that is separated from the latch member toward the driver's seat in the left-right direction.

FIG. 2A shows a latch mechanism 8 including an operation unit 7.
2B is an enlarged plan view showing the lock device 9, and FIG. 2B is a partial cross-sectional rear view of FIG. As shown in each figure,
The latch mechanism 8 is rotatable with a base member 10 extending left and right in the lid 5 and a rotation shaft 12 at one end side (passenger seat side) of the base member 10 to engage with the striker 6. And a slider 13 supported by the base member 10 so that one end of the latch member 11 is selectively engaged with the latch member 11 so that the latch member 11 can be selectively rotated. And The other end of the slider 13 is connected to the operation unit 7 provided on the other end side (driver's seat side) of the base member 10.

As shown in FIG. 2B taken along the line V--V in FIG. 2, a striker engaging groove 11a is formed in the peripheral portion of the latch member 11, and when the lid 5 is closed, The engagement groove 11 a is adapted to engage with the striker 6. Also, the striker engagement groove 1 of the latch member 11
A slider engaging groove 11b is formed in a peripheral portion opposite to 1a so that the slider engaging groove 11b can be engaged with the one end of the slider 13. The latch member 11 includes a torsion coil spring 14
Is biased in a direction to release the engagement state with the striker 6. Further, the slider 13 is slidable between a first position where the slider 13 is engaged with the latch member 11 to inhibit rotation of the latch member 11 and a second position where the latch member 11 is rotatable. I have.

The other end of the slider 13 is engaged with an operation button 17 supported on the casing 16 of the operation section 7 so as to be able to protrude and retract in the left-right direction. When the operation button 17 is immersed, that is, when the operation button 17 is operated, the slider 13 is in the second position. The operation button 17 and the slider 13 are urged by a compression coil spring 18 in a direction in which the operation button 17 protrudes, that is, in a direction in which the slider 13 moves toward the first position.

On the other hand, the lock device 9 selectively inhibits / permits the operation of opening the lid 5, that is, the latch member 11 of the latch mechanism.
Is a device for selectively fixing / un-fixing in a state in which it is engaged with the striker 6, and the annular boss 1 of the base member 10
0a, and a rotary solenoid 21 that rotatably drives the lock member 20.
And The rotary solenoid 21 transmits and receives signals by inserting / removing a keyless entry system (not shown) and / or an ignition key into / from a key hole near a handlebar of a driver's seat, thereby preventing / preventing the vehicle from being stolen. Based on a signal from the device, it is connected to a control device 22 for recognizing that a regular occupant has boarded, and is selectively energized.

The lock member 20 has a substantially cylindrical shape having a notch 20a on a part of the outer peripheral surface.
The notch portion 20a is aligned with the end face of the operation button 17 to allow the operation button 17 to be immersed, and to enable the latch member 11 and the striker 6 to be disengaged from each other at a first rotation position (FIG.
2B), the notch 20a is not aligned with the end face of the operation button 17, that is, the cutout 20a is in contact with the outer peripheral surface to prevent the operation button 17 from being immersed, and the latch member 11 is engaged with the striker 6. The second rotational position (FIGS. 3B and 4) to be fixed can be taken. And usually, the lock member 20
Is the second rotational position, and rotates to the first position only when the control device 22 energizes the rotary solenoid 21. The balls and the compression coil springs indicated by reference numerals 23 and 24 are provided to prevent the backlash of the lock member 20 from occurring.

On the other hand, as shown in FIG. 5, the operation unit 7 is provided with a proximity sensor 25. When the operation button 17 is approached without being operated while the regular passenger is being recognized, the rotary solenoid 2 is detected and operated only when the operation button 17 is detected and operated.
1 is energized. As a result, the power consumption is suppressed as compared with the case where the power is always supplied while the legitimate passenger is aware. Needless to say, a touch sensor or a limit switch for detecting the start of operation may be used instead of the proximity sensor.

The operation of the glove box according to the present embodiment will be described below with reference to FIG. 6 showing an unlatched state, that is, a state in which the lid 5 is opened, and FIG. 7 showing a latched state. First, the control device 22 determines that a regular passenger has boarded.
Is recognized, that is, the door is unlocked by the keyless entry system, or the ignition key inserted into the ignition switch is recognized as a legitimate key. As described above, power is not supplied to the rotary solenoid 21 as it is, and the lock member 20 is at the second rotation position (FIG. 3B).

When the cover 5 is closed in the direction of arrow A from the open state (FIG. 6), the striker 6 comes into contact with the contact portion 11c provided above the striker engagement groove 11a of the latch member 11, and this latch The member 11 is rotated clockwise in the figure against the urging force of the torsion coil spring 14, and the striker 6 is engaged with the striker engaging groove 11a. Then, the slider 13, which has been in contact with the side surface of the latch member 11 by the urging force of the compression coil spring 15, engages with the slider engagement groove 11 b with the rotation of the latch member 11 to maintain this latched state. Are kept closed (FIG. 7).

When the passenger gets off the vehicle in this state, the control device 22 recognizes this, that is, when the door is locked by the keyless entry system or when the ignition key is removed from the ignition switch, the proximity sensor 25 is detected.
Even if the operation of the operation button 17 is detected, the energization of the rotary solenoid 21 is interrupted, that is, the lock member 20 is moved to the second rotation position (see FIG. 4) by the urging force of the return spring (not shown) in the rotary solenoid 21. 3 (b)). Therefore, the notch 20a is
And the end face of the operation button 17 is not aligned with the lock member 20.
The latch member 11 is fixed in a state in which the latch member 11 is engaged with the striker 6 by abutting on the outer peripheral surface of the strike button 6 to prevent the operation button 17 from being immersed. Even if the operation button 17 is pressed in this state, the lid 5 cannot be opened. Here, when the operation button 17 is forcibly pressed when the lock member 20 is at the second rotation position, there is a concern that an excessive load is applied to the rotation shaft 21a of the rotary solenoid 21. However, the locking member 20
A long hole 20 extending parallel to the sliding direction of the slider 13 when the lock member 20 is at the second rotational position.
b is provided, and the chamfered rotating shaft 21a is
, The rotary solenoid 21 and the lock member 20 are engaged with each other, and the elongated hole 20b has a gap L when the rotary shaft 21a is fitted. Further, the lock member 20 is supported by the annular boss 10a of the base member 10. Therefore, there is actually no concern since the load is actually received by the base member 10 via the lock member 20.

Next, if the operation of the operation button 17 is detected by the proximity sensor 25 while the legitimate occupant gets on the vehicle again and the control device 22 recognizes it, the rotary solenoid 21 is only activated at that time. The power is supplied, and the lock member 20 is held in a state rotated from the second position to the first rotation position. Then, the notch 20a is aligned with the end face of the operation button 17 to allow the operation button 17 to be immersed, and the engagement between the latch member 11 and the striker 6 can be released.

When the cover 5 is opened in this state, the operation buttons 17
Is retracted against the urging force of the compression coil spring 15, that is, the slider 13 is pulled out of the slider engaging groove 11b against the urging force of the compression coil spring 15. Then, the torsion coil spring 14 engaged with the dead weight of the lid 5 and the latch member 11
, The latch member 11 rotates counterclockwise,
The engagement state between the striker 6 and the striker engagement groove 11a is released, and the lid 5 can move in the direction of arrow B, that is, the opening direction.

In the present embodiment, a rotary solenoid which rotates by a predetermined angle when energized and returns to its original position by the biasing force of a return spring when energized is cut off is used as a driving device of the lock device in this embodiment. Alternatively, the position may be controlled using an actuator having a structure such as a stepping motor.

It is supposed to.
That is, the shaft member 30 is in a retracted position (a broken line in FIG. 8) at which the engagement between the latch member 11 and the striker 6 can be released, and a projecting position (FIG. 8) in which the latch member 11 and the striker 6 are fixed in an engaged state. Solid line).
Normally, the shaft member 30 is protruded by a return spring (not shown) in the solenoid 31, and the shaft member 30 is immersed only when the solenoid 31 is energized by the control device 22 and the latch member 1
The engagement between the striker 1 and the striker 6 can be released. here,
The shaft member 30 is provided with a guide hole 32 provided in the base member 10.
Even when the operation button 17 is forcibly pressed when the shaft member 30 is projected, an excessive force is applied to the solenoid 31 since the load is applied to the side wall of the guide hole 32, that is, the base member 10. Don't worry. The operation procedure of the present embodiment is the same as that of the above-described embodiment, and a description thereof will be omitted.
