Description

  The present invention relates to a vehicle feeding device that is mounted on a vehicle and quickly moves from a standby position to a feeding position of a feeding portion that is drawn out to receive a protection object such as a pedestrian or an occupant during operation. The present invention relates to a vehicle feeding device that pushes out a feeding portion that supports a hood panel and the like so that the hood panel is pushed up at the time of a collision with a pedestrian and the hood panel that is pushed up can relieve an impact and receive the pedestrian.

  Conventionally, as this type of vehicle feeding device, one that pushes up a hood panel when a pedestrian collides with a vehicle is known (for example, see Patent Document 1).

  As this feeding device, the feeding portion that supports the vicinity of the lower part of the front end of the hood panel, the spring that is the driving source for moving the feeding portion, and the feeding portion that is compressed so as to bend the spring is locked in the standby position. And an actuator that is actuated to release the locking of the locking portion. The spring moves the feeding portion to the feeding position by applying a restoring force (repulsive force) by releasing the locking of the feeding portion in the locking portion by the operation of the actuator.

  Specifically, driving springs for pushing the feeding portion upward are compressed and arranged on both the left and right sides of the feeding portion arranged in the horizontal direction, and the locking portion is provided with a saddle member and is arranged in the feeding portion. It was set up. The saddle member was locked to the case that houses the feeding portion in a state of being urged by the auxiliary spring so as to extend to the left and right sides. The actuator was disposed with a wedge provided at the center of the left and right saddle members. The actuator is configured as a gunpowder type, and operates to push down the wedge downward during operation. Then, the saddle material as the left and right engaging portions moves to the center in the left and right direction by the biasing force of the auxiliary spring to release the engaging state with the case, and the feeding portion is moved upward by the drive spring. The hood panel was pushed up.

  As another feeding device, when a vehicle collision is predicted, a reversible actuator including an electric motor is operated to feed out the feeding unit, and during an actual vehicle collision, a gunpowder type actuator is operated to feed out the feeding unit. Those are known (for example, see Patent Document 2). In this feeding device, after the reversible actuator is operated, if there is no actual vehicle collision, the reversible actuator is driven in reverse to return the feeding portion to the initial position to prepare for the next vehicle collision. I was able to.

JP 2006-513097 A JP 2010-083172 A

  However, in the conventional feeding device of Patent Document 1, a spring is used as a driving source for feeding out the feeding portion, and the spring is pressed against the bent spring so that the restoring force of the bent spring can be used as the driving source. Unlocking of the locking part that locks the feeding part in the state is performed using a gunpowder type actuator, and when it is configured to operate at the time of vehicle collision prediction, there is no actual collision after that When the collision is avoided, the actuator must be replaced, which is inconvenient.

  Further, in the conventional feeding device disclosed in Patent Document 2, even if the reversible actuator is operated at the time of collision prediction, if the collision is avoided, the reversible actuator is reversed to return the feeding portion to the initial position. We were able to prepare for a vehicle crash.

  However, in the feeding device of Patent Document 2, an explosive actuator or a reversible actuator is used as a drive source for feeding out the feeding unit, and these actuators are driven over the entire feeding distance of the feeding unit during feeding. The problem is that the device becomes simple, including securing the strength of the movable part of the actuator and the part of the feeding part that receives the movable part. was there.

  The present invention solves the above-described problems, and enables the feeding portion to be fed out at the time of collision prediction and at the time of collision, and can be handled without replacement of parts when collision is avoided, and is simplified. An object of the present invention is to provide a vehicle feeding device that can be configured.

<Explanation of Claim 1>
A vehicle feeding device according to the present invention is a vehicle feeding device that is mounted on a vehicle and moves a feeding unit that is fed out to receive a protection object from a standby position to a feeding position during operation.
A spring serving as a drive source for moving the feeding portion;
The feeding portion is locked at the standby position with the spring bent, and the feeding portion is locked so that the restoring portion of the spring is moved to the feeding position when the lock is released. A locking part;
An actuator for moving the locking portion so that the locking portion is shifted from the locked state to the unlocked state, and when the combustion gas generated by the ignition of the chemical is used as an operating fluid during operation, the locking An explosive actuator that operates to move the part,
A reversible actuator that moves the locking portion so as to be in the unlocked state from the locked state of the feeding portion, and that operates to be able to return to the state before operation;
By controlling the operation of the explosive actuator and the reversible actuator, the explosive actuator is operated when a vehicle collision detection signal is input, and the reversible actuator is operated when a vehicle collision prediction signal is input. A control device;
And configured with
The feeding portion includes a locked portion that is locked to the locking portion,
The locking portion is configured to be provided with a biasing means that biases the locked portion in a direction of locking.
When the locking portion is returned to the standby position of the feeding portion after feeding, the latching portion is locked while being pushed back to the locked portion by using a biasing force of the biasing means. A restoring sliding portion that slides on the locked portion is provided so as to restore to the locked state.

  In the vehicle feeding device according to the present invention, the control device operates the explosive actuator when a vehicle collision detection signal is input. Then, since the movable part of the explosive actuator moves the locking portion so as to be in the unlocked state, the restoring force of the bent spring acts on the feeding portion, and the feeding portion uses the spring as a drive source. Then, it is fed from the standby position to the feeding position. In addition, since this explosive actuator moves the latching portion using the combustion gas generated by the ignition of the chemical as the working fluid during operation, the latching portion can be moved more quickly than the reversible actuator. Thus, it is suitable as an actuator that operates when the control device inputs a collision detection signal for detecting the actual collision of the vehicle.

  Further, the control device operates the reversible actuator without operating the explosive actuator when the vehicle collision prediction signal is input. Then, since the reversible actuator moves the locking portion so as to be in the unlocked state, the restoring force of the bent spring acts on the feeding portion, and the feeding portion uses the spring as a drive source and is in a standby position. To the feeding position.

  If the collision is avoided after the operation of the reversible actuator, the feeding portion can be returned to the standby position. At that time, the locking portion uses the urging force of the urging means, slides the restoring sliding portion on the locked portion, and smoothly pushes back the locked portion while being pushed back to the locked portion. Can be restored to the locked state.

  Therefore, if there is no actual vehicle collision after the operation of the reversible actuator, the reversible actuator is reversely driven as appropriate, and the return portion is returned to the standby position, so that the restoration slides on the locked portion. Using the biasing means that biases the sliding part and the locking part into the locked state, the locking part can be smoothly restored to the locked state in which the locked part is locked, and the explosive actuator is not used. In the vehicle feeding device according to the present invention, when a collision is avoided, the vehicle can be prepared for the next collision without replacing parts.

  In addition, the vehicular feeding device according to the present invention uses the drive source that feeds the feeding portion as a spring, and the reversible actuator and the explosive actuator can be fed by simply moving the locking portion to the unlocked state during operation. Since the actuator is not moved to the feeding position, the operating stroke of each actuator can be reduced, the strength of the part of the engaging part linked to the movable part of each actuator can be reduced, and the feeding device can be made simple and compact. Can be configured.

  Therefore, in the vehicle feeding device according to the present invention, the feeding unit can be fed at the time of collision prediction and at the time of collision, and can be handled without replacing parts when collision is avoided, and simple Can be configured.

<Explanation of Claim 2>
In the vehicle feeding device according to the present invention, the locking portion is supported by a support shaft and is rotatably disposed, and the locking portion extends from the support shaft side so as to be locked to the locked portion. A single piece, and a connecting piece that extends from the support shaft side and is connected to a movable part that operates during operation of the reversible actuator.
The explosive actuator presses the locking piece so that the movable part that operates during operation is separated from the locking piece in a state before operation and rotates in the unlocking direction during operation. It is desirable that it be arranged as possible.

  In such a configuration, the movement of the locking portion that locks the locked portion from the locked state to the unlocked state is rotation around the support shaft. Therefore, when the reversible actuator moves the locking portion to the unlocked state, that is, so that the locking portion is removed from the locked portion in the state of receiving the biasing force of the bent spring. Even if a strong force is required when rotating, if the length dimension from the support shaft of the connecting piece to the connecting part of the reversible actuator is set large, the rotational moment can be secured and reversible. The type actuator can easily move the locking portion to the unlocked state. And even if the biasing force of the spring is large, the reversible actuator can smoothly move the locking portion to the unlocking state, so that the spring biasing force (restoring force) can be set large, The feeding speed and feeding output of the feeding unit can be increased.

  In addition, since the movable part of the explosive actuator is separated from the engaging piece of the engaging part in the state before the operation, the reversible actuator is independent of the explosive actuator without being affected by the explosive actuator. Thus, the locking part can be moved to the unlocked state.

<Explanation of Claim 3>
In the vehicle feeding device according to the present invention, when the control device inputs the vehicle collision prediction signal and operates the reversible actuator and then inputs the vehicle collision detection signal, the explosive actuator It is desirable not to operate.

  In such a configuration, even if there is an actual vehicle collision after the operation of the reversible actuator, at that time, the locking portion has already moved to the unlocked state by the operation of the reversible actuator, and the spring Exerts the restoring force and arranges the feeding portion at the feeding position.

  For this reason, if the reversible actuator is already operated and the feeding portion is disposed at the feeding position, the explosive actuator need not be actuated. And after a vehicle collision, a delivery part is returned to a stand-by position, and parts can be reused, suppressing parts exchange as much as possible.

  That is, when the feeding portion is returned to the standby position, the locking portion is pushed back to the locked portion by using the biasing force of the biasing means and sliding the restoring sliding portion on the locked portion. However, it is possible to smoothly restore the locked state in which the locked portion is locked.

  Therefore, if the reversible actuator operates, even if there is no actual vehicle collision, or even if there is an actual vehicle collision, the reversible actuator is then reversely driven as appropriate, and the feeding section is set to the standby position. If it is returned to, the restoring sliding part that slides on the locked part and the urging means that urges the locking part to the locked state are used, and the locked part smoothly moves the locked part. The locked state can be restored, and the explosive actuator is not used. In the vehicle feeding device according to the present invention, even if a collision is avoided or there is an actual collision, the parts are not replaced as much as possible. In preparation for the next collision.

The front end 5a and the rear end 5b of the hood panel 5 are raised, and a pedestrian as a protection object can be received by the hood panel 5 which is raised from the engine room ER and can be reduced in impact force. As described above, the feeding portion 11 is moved together with the hood panel 5 from the standby position WP to the feeding position SP. The feeding device VS1 of the first embodiment is arranged at four locations on the left and right sides of the front end 5a and the rear end 5b of the hood panel 5, and each has a feeding unit 11 (10F, 10F, 10F, 10F, 10F, 10F). 10R, 10R), and a control device 101 that inputs signals from predetermined sensors 102 and 103 and controls the operation of each feeding unit 10.

  The feeding portion 11 of the feeding unit 10F on both the left and right sides of the front end 5a of the hood panel 5 holds a hood lock device 6 including a lock striker 6a, a latch 6b, and the like, and when feeding to the feeding position SP, The front end 5a of the hood panel 5 is raised together with the hood lock device 6. The feeding portions 11 of the feeding unit 10R on the left and right sides of the rear end 5b of the hood panel 5 hold the hinge device 7 including the hinge base 7a and the hinge arm 7b, and each hinge device 7 is fed to the feeding position SP. The rear end 5b of the hood panel 5 is raised.

  The sensor 102 includes an acceleration sensor, a pressure sensor, and the like disposed in the front bumper 4 of the vehicle V, and is a collision detection sensor 102 that can detect an actual collision with a pedestrian vehicle V. The sensor 103 is A collision prediction sensor 103 comprising a millimeter wave radar, a camera or the like that can detect a pedestrian's approach to the vehicle V and predict a collision with the pedestrian's vehicle V in the vicinity of a rearview mirror (not shown) on the indoor side of the vehicle V. is there. And the control apparatus 101 which input the signal from the collision detection sensor 102 or the collision prediction sensor 103 is comprised so that each feeding unit 10 (10F, 10F, 10R, 10R) may be operated simultaneously.

  Further, the feeding unit 10F on the front end 5a side of the hood panel 5 is provided with a case 45 to be described later attached to a support member 8 as a body side supporting member that supports a radiator or the like, and the rear end 5b side of the hood panel 5 The feeding unit 10R is provided with a case 45 attached to a hood ridge rein hose 9 as a body side support member. The front feeding unit 10F is arranged with the longitudinal direction of the cross section of the case 45 along the left-right direction, and the rear feeding unit 10R is arranged with the longitudinal direction of the cross section of the case 45 along the front-rear direction. Thus, although the arrangement direction of the case 45 and the arrangement position on the body side support member are different, these feeding units 10F and 10R are the same.

  As shown in FIGS. 3 and 4, each feeding unit 10 includes a feeding portion 11, a compression coil spring 18, a lock lever 20, a torsion spring 31, an explosive actuator 35, a case 45, and a reversible actuator. As an electromagnetic solenoid 55. The explosive actuator 35 uses the combustion gas generated by the ignition of the chemical as the working fluid, and the gas generator 37 that receives the operation signal from the control device 101 generates the combustion gas, which is movable by the combustion gas. The piston rod 38 as a part is rapidly protruded along the feeding direction SD.

  Then, when the collision detection signal from the collision detection sensor 102 is input, the control device 101 operates the actuator 35 of each feeding unit 10 so that each feeding unit 11 can be fed quickly, thereby predicting the collision. When the collision prediction signal from the sensor 103 is input, control is performed so that the electromagnetic solenoid 55 of each feeding unit 10 is operated, and the operation of the actuator 35 is, for example, actual with the pedestrian vehicle V. About 30 ms after the collision, the operation of the electromagnetic solenoid 55 is performed before the collision with the pedestrian vehicle V, for example, about 100 ms before the actual collision.

  In the first embodiment, even if the control device 101 operates the electromagnetic solenoid 55 as a reversible actuator for each feeding unit 10 and then inputs a signal from the collision detection sensor 102, the explosive actuator It is set so that 35 is not operated.

  In the description of the feeding unit 10, unless otherwise specified, as shown in FIGS. 3 and 4, the longitudinal direction of the transverse section of the rectangular parallelepiped case 45 is assumed to be in a state in which it is aligned in the left-right direction.

  The case 45 of the feeding unit 10 is attached to a support member 8 or a hood ridge rein hose 9 as a body side support member, and accommodates components such as a compression coil spring 18 therein. The case 45 is made of sheet metal or the like, and has a rectangular bottom wall portion 46, a peripheral wall portion 48 extending upward from the outer peripheral edge of the bottom wall portion 46, and a support wall portion 47 disposed above the bottom wall portion 46. , And is configured. An actuator 35 and an electromagnetic solenoid 55 are attached on the bottom wall portion 46.

  On the support wall portion 47, spring seats 47a each having a columnar support portion 47b are disposed on both the left and right sides, and the lower end of the compression coil spring 18 is assembled to each spring seat 47a. Further, an insertion hole 47c through which a later-described connecting piece portion 28 side of the lock lever 20 is inserted is formed in the support wall portion 47 on the side of the actuator 35 between the compression coil springs 18 and 18. It can swing. Note that the right edge side of the inner peripheral surface of the insertion hole 47c does not return excessively counterclockwise in FIG. 3 even if the lock lever 20 receives the biasing force of the return torsion spring 31 (in other words, When the payout portion 11 is returned, the lock pin 17 (to be described later) is brought into smooth contact with the restoring slide surface 27 as a restoring slide portion (to be described later) of the lock lever 20 and can be slid. The regulation surface 47d is regulated.

  Guide grooves 50 extending along the feeding direction SD of the feeding portion 11 (in other words, extending along the vertical direction) are disposed on the side walls 49, 49 facing each other in the left-right direction of the peripheral wall portion 48. In these guide grooves 50, stopper pins 15 provided in the feeding portion 11 are disposed. The guide groove 50 is configured as a feeding-side regulating surface 50a for regulating the position of the stopper pin 15 so that the upper edge side is stopped at the feeding position SP. In addition, the lower edge side of the guide groove 50 is configured so that a gap is formed between the guide pin 50 and the stopper pin 15 even when the feeding portion 11 is stopped at the standby position WP.

  Furthermore, between the side walls 51 and 51 which oppose in the front-back direction in the surrounding wall part 48, the support shaft 21 along the front-back direction is adhering to the approximate middle position of the up-down direction. The support shaft 21 supports the lock lever 20 so as to be rotatable along the left-right direction.

  At the upper ends of the left and right side walls 49, 49, mounting portions 52 for fixing the feeding unit 10 to the support member 8 and the hood ridge liner hose 9 are disposed.

  The feeding portion 11 is disposed so as to fit inside the upper end side of the case 45, and has a rectangular plate-like holding wall portion 12 that holds the hood lock device 6 and the hinge device 7, and an outer peripheral edge of the holding wall portion 12. And a peripheral wall portion 13 that extends downward. On the side walls 14, 14 facing the circumferential wall portion 13 in the left-right direction, the above-described stopper pin 15 that fits into the guide groove 50 is provided in a projecting manner.

  The compression coil springs 18 and 18 are disposed between the support wall portion 47 of the case 45 and the holding wall portion 12 of the feeding portion 11, and always urge the holding wall portion 12 upward. In the case of the embodiment, these springs 18 are configured to have a restoring force (repulsive force, urging force) capable of abruptly pushing up the hood panel 5 together with the hood lock device 6 and the hinge device 7.

  Furthermore, a lock pin 17 along the front-rear direction is fixed above the support shaft 21 on the side walls 16, 16 facing the peripheral wall portion 13 in the front-rear direction. The lock pin 17 constitutes a locked portion that is locked to the locking piece portion 22 of the lock lever 20, and is formed of a metal round bar.

  The lock lever 20 constitutes a locking portion that locks the feeding portion 11 so as to stop at the standby position WP, and includes a locking piece portion 22 extending from the support shaft 21 in the feeding direction SD, and a support shaft. And a connecting piece portion 28 extending downward from 21. The lock lever 20 is supported by a support shaft 21 so as to be swingable in the left-right direction, and further, a direction in which the lock pin 17 is locked by a torsion spring 31 as an urging means disposed around the support shaft 21. In other words, it is biased counterclockwise in FIG.

  The locking piece portion 22 includes a neck portion 23 that extends upward from the support shaft 21, and a triangular plate-shaped head portion 24 that protrudes to the left on the upper end side of the neck portion 23. In the head 24, the lower surface side on the support shaft 21 side is a locking surface 25 for locking the lock pin 17, and the upper surface side away from the support shaft 21 is a restoring sliding surface 27 as a restoring sliding portion. The locking surface 25 is provided in the vicinity of the neck portion 23 in a direction orthogonal to the neck portion 23, and an orthogonal surface portion 25 a that locks the lock pin 17 without detaching is disposed. A contact surface portion 25b that extends while turning in an obliquely upward direction away from the neck portion 23 is disposed on the reversing top portion 26 side that is a boundary between the contact surface portion 25b and the contact surface portion 25b. The abutting surface portion 25b becomes a portion that abuts on a later-described locking portion pressing surface 43a of the actuator 35. When the actuator 35 is operated and the abutting surface portion 25b is pushed up, as shown in FIGS. The lever 20 rotates in the clockwise direction around the support shaft 21, so that the locking surface 25 of the locking piece 22 is disengaged from the lock pin 17 and the locking is released.

  When the lock lever 20 of each feeding unit 10 is unlocked, each feeding portion 11 is pushed upward by the restoring force of the springs 18, 18, and the hood lock device 6 and the hinge device 7 together with the hood panel 5. The whole of will rise.

  The restoring sliding surface 27 is formed so as to extend obliquely upward from the inverted top 26. As shown in FIGS. 7 to 9, the restoring sliding surface 27 uses the biasing force of the torsion spring 31 when the locking piece portion 22 returns to the standby position WP of the feeding portion 11 after feeding. Further, it is formed so as to slide with the guide surface (outer peripheral surface) 17 a of the lock pin 17 so as to be restored to the locked state in which the lock pin 17 is locked while being pushed back by the lock pin 17.

  The connecting piece 28 protrudes downward through the insertion hole 47 c of the support wall 47 of the case 45, and the lower end is connected to the operating part (movable part) 56 of the electromagnetic solenoid 55 using the connecting shaft 29.

  The electromagnetic solenoid 55 is of a push type, and operates when the operation signal from the control device 101 is input so that the operation portion 56 made of a movable iron core protrudes to the left side. 3 rotates in the clockwise direction in FIG. 3, and the locking piece portion 22 comes off the lock pin 17 (see FIGS. 5 and 6).

  The length CL of the connecting piece portion 28 from the support shaft 21 to the connecting shaft 29 is such that the lock pin 17 urged upward by the springs 18 and 18 when the electromagnetic solenoid 55 is actuated engages the engaging piece portion 22. Even if the frictional force with respect to the surface 25 is increased, the dimension is set so that a sufficient rotational moment can be applied so that the lock lever 20 can be rotated in the clockwise direction in FIG. ing.

  Further, after the lock lever 20 is removed from the lock pin 17, if the energization to the electromagnetic solenoid 55 is stopped, the connecting piece portion 28 is inserted into the insertion hole 47 c of the support wall portion 47 by the urging force of the torsion spring 31. A state in which the restoring sliding surface 27 is disposed immediately below the lock pin 17 that has been rotated counterclockwise so as to abut against the regulating surface 47d on the inner peripheral surface of the roller and that has been raised with the feeding of the feeding portion 11. It becomes.

  The explosive actuator 35 has a gas generator 37 that generates combustion gas by ignition of a chemical agent disposed in the cylinder 36, and the combustion gas of the gas generator 37 serves as a movable part disposed in the cylinder 36. The piston rod 38 is lifted. The piston rod 38 includes a piston portion 39 in the vicinity of the gas generator 37 and a rod portion 40 extending upward from the piston portion 39. The head 41 as a tip portion (upper end portion) of the rod portion 40 includes a flange portion 43 that expands in a direction substantially orthogonal to the axis, and a small diameter portion 42 that protrudes upward from the center of the flange portion 43. . As shown in FIGS. 10 and 11, the upper surface of the collar portion 43 is a tapered surface that tapers toward the upper side so that the lock pin 17 in the lock lever 20 is unlocked. The locking portion pressing surface 43a is in contact with the contact surface portion 25b of 22 and rotates the lock lever 20 in the clockwise direction around the support shaft 21. The distal end surface of the small-diameter portion 42 is a feeding portion pressing surface 42a that pushes up the holding wall portion 12 of the feeding portion 11 as a plane along a horizontal plane.

  10 and 11, when the actuator 35 is operated, the head 41 of the actuator 35 comes into contact with the abutment surface portion 25b of the engagement piece portion 22 so that the lock lever 20 is moved clockwise. As shown in FIG. 12, when the outer edge 43b and the vicinity of the engaging portion pressing surface 43a are raised to a position where they come into contact with the inverted top portion 26, the feeding portion pressing surface 42a is moved to the feeding portion 11 as shown in FIG. It is comprised so that it may contact | abut to the holding wall part 12.

  At this time, the lock lever 20 is rotated to a position where the lock pin 17 is disengaged from the orthogonal surface portion 25a and disposed on the contact surface portion 25b in the vicinity of the orthogonal surface portion 25a. For this reason, the lock lever 20 is pressed against the abutment surface portion 25b by the lock pin 17 provided on the feeding portion 11 which is pushed up by the urging force of the compression coil springs 18 and 18 and the operation of the actuator 35, and FIG. , 13, it rotates in the clockwise direction and is disengaged from the lock pin 17.

  Moreover, the actuator 35 makes the operation stroke AL of the piston rod 38 as a movable part shorter than the feeding distance SL of the feeding part 11 by the compression coil spring 18. In the case of the embodiment, the operation stroke AL is about 70% of the feeding distance SL, and the feeding portion 11 is pressed against the feeding portion 11 only by a distance about half of the feeding distance SL.

  In the feeding device VS1 of the first embodiment, for example, when a pedestrian suddenly jumps out from the side of the vehicle V and collides with the vehicle V, the control device 101 outputs a signal from the collision prediction sensor 103. Without input, a collision detection signal from the collision detection sensor 102 is input, and an ignition signal is output to the gas generator 37 of the actuator 35 of each feeding unit 10.

  Then, as shown in FIGS. 10 to 12, the piston rod 38 as the movable part of the explosive actuator 35 of each feeding unit 10 (10F, 10F, 10R, 10R) rises, and the head 41 is engaged with the locking piece portion 22. Since the locking lever 20 as the locking portion is rotated in the clockwise direction so as to be in the unlocked state, the restoring force of the bent springs 18 and 18 is brought out by the feeding portion 11. The feeding portion 11 is fed from the standby position WP to the feeding position SP using the springs 18 and 18 as drive sources, and as a result, the entire hood panel 5 is raised to reduce the impact and reduce the hood. Panel 5 can catch a pedestrian.

  Since the explosive actuator 35 moves the lock lever 20 using the combustion gas generated by the ignition of the chemical as the working fluid during operation, the lock lever 20 is more quickly operated than the electromagnetic solenoid 55 as a reversible actuator. 20 can be moved, and is suitable as an actuator that operates when the control device 101 inputs a collision detection signal for detecting the actual collision of the vehicle.

  Further, in the feeding device VS1 of the first embodiment, for example, when the pedestrian approaches the vehicle V and the vehicle V cannot avoid the collision with the pedestrian, the control device 101 can predict the collision. Receives a collision prediction signal from the collision prediction sensor 103 and outputs a signal for operating the electromagnetic solenoid 55 of each feeding unit 10.

  Then, in each feeding unit 10 (10F, 10F, 10R, 10R), the operating portion 56 of the electromagnetic solenoid 55 is pushed out, and the lock lever 20 is moved around the support shaft 21 as shown in FIGS. Rotating in the turning direction, the locking surface 25 is disengaged from the lock pin 17 and the locking is released, so that the feeding portion 11 is fed from the standby position WP to the feeding position SP by the urging force of the compression springs 18 and 18. Thus, the entire hood panel 5 can be raised.

  Then, after the operation of the electromagnetic solenoid 55 as the reversible actuator, if the collision is avoided, the entire hood panel 5 can be lowered and the feeding portion 11 can be returned to the standby position WP. That is, at that time, the lock lever 20 as the locking portion uses the biasing force of the torsion spring 31 to slide the restoring slide surface 27 on the guide surface 17a of the lock pin 17, and first, FIG. As shown in FIG. 8, it is rotated clockwise while being pushed back by the lock pin 17. Next, as shown in FIGS. 8 and 9, the lock lever 20 rotates counterclockwise by the biasing force of the torsion spring 31 when the reversing top portion 26 gets over the lock pin 17, and is orthogonal to the locking surface 25. The lock pin 17 can be disposed at the position of the surface portion 25a to restore the locked state in which the lock pin 17 is locked.

  Therefore, after the operation of the electromagnetic solenoid 55 as the reversible actuator, if there is no actual collision of the vehicle V, the energization to the electromagnetic solenoid 55 is appropriately stopped and the operation unit 56 is reversely driven while each feeding unit 11 is reversely driven. As a biasing means for biasing the restoring sliding surface 27 sliding on the lock pin 17 and the lock lever 20 into the locked state. Using the torsion spring 31, the lock lever 20 as the locking portion can be smoothly restored to the locked state in which the lock pin 17 is locked, the explosive actuator 35 is not used, and the vehicle for the first embodiment is used. The feeding device VS1 can prepare for the next collision without replacing parts when the collision is avoided.

  Further, in the feeding device VS1 of the first embodiment, the drive source that feeds the feeding unit 11 of each feeding unit 10 is the springs 18 and 18, and the electromagnetic solenoid 55 and the explosive actuator 35 as the reversible actuator are in operation. Since only the lock lever 20 as the locking portion is moved to the unlocked state and the feeding portion 11 is not moved to the feeding position SP, the operating strokes of the actuators 35 and 55 can be reduced. 55, the strength of the engaging portion (the contact surface portion 25b of the head 24 and the connecting shaft 29 of the connecting piece portion 28) interlocked with the movable portion (the piston rod 38 and the operating portion 56) can be reduced. The device VS1 can be configured simply and compactly.

  Therefore, in the feeding device VS1 of the first embodiment, the feeding unit 11 can be fed at the time of collision prediction and at the time of collision, and can be handled without replacing parts when the collision is avoided, and It can be simply configured.

  In the embodiment, the electromagnetic solenoid 55 is exemplified as the reversible actuator. However, an electric actuator, an air cylinder, a hydraulic cylinder, or the like is used as long as the movable part (operation part) at the time of operation can be restored (recoverable). May be.

  Further, in the feeding device VS1 of the first embodiment, the lock lever 20 as the locking portion is supported by the support shaft 21 and is rotatably disposed, and is engaged with the lock pin 17 as the locked portion. A locking piece 22 that extends from the support shaft 21 side so as to be able to stop, and a connecting piece that extends from the support shaft 21 side and is connected to an operating portion 56 that is a movable part that operates during operation of the electromagnetic solenoid 55 as a reversible actuator. And a portion 28. Further, the explosive actuator 35 is configured so that the piston rod 38 as a movable part that operates at the time of operation is separated from the locking piece portion 22 in a state before the operation, and is rotated in the unlocking direction at the time of operation. The locking piece 22 is arranged so as to be pressed.

  Therefore, in the feeding device VS1 of the embodiment, the movement from the locking state of the lock lever 20 as the locking portion that locks the lock pin 17 as the locked portion to the unlocking state is performed around the support shaft 21. It becomes rotation. Then, when the electromagnetic solenoid 55 moves the lock lever 20 to the unlocked state, that is, the lock lever 20 is removed from the lock pin 17 in the state of receiving the biasing force of the bent springs 18, 18. Even when a strong force is required when rotating 20, if the length dimension CL from the support shaft 21 to the connection portion of the electromagnetic solenoid 55 in the connection piece portion 28 is set large, the rotational moment is reduced. The electromagnetic solenoid 55 can easily move the lock lever 20 to the unlocked state. Even if the urging force of the spring 18 is large, the electromagnetic solenoid 55 can smoothly move the lock lever 20 to the unlocked state, and conversely, the urging force (restoring force) of the spring 18 can be set large, and The feeding speed and feeding output of the feeding unit 11 at the time can be increased.

  The explosive actuator 35 has a piston rod 38 as a movable part separated from the locking piece 22 of the lock lever 20 in a state before the operation, so that the electromagnetic solenoid 55 as a reversible actuator is The lock lever 20 can be independently moved to the unlocked state without being affected by the explosive actuator 35.

  Further, in the feeding device VS1 of the first embodiment, after the control device 101 inputs a collision prediction signal of the vehicle V and operates the electromagnetic solenoid 55 as a reversible actuator of each feeding unit 10, the collision of the vehicle V is performed. When the detection signal is input, the explosive actuator 35 is set not to operate.

  In such a configuration, even if there is a collision with the pedestrian of the actual vehicle V after the operation of the electromagnetic solenoid 55, the lock lever 20 is already in the unlocked state by the operation of the electromagnetic solenoid 55. The springs 18 and 18 exhibit restoring force, the feeding portion 11 is disposed at the feeding position SP, and the hood panel 5 is raised.

  Therefore, if the electromagnetic solenoid 55 is already actuated and the feeding part 11 is disposed at the feeding position SP, the explosive actuator 35 need not be actuated. If the feeding unit 11 is returned to the standby position WP after the collision of the vehicle V, parts replacement can be suppressed as much as possible, and each part can be reused.

  That is, if the feeding portion 11 of each feeding unit 10 is returned to the standby position WP while pushing down the hood panel 5, the lock lever 20 uses the biasing force of the torsion spring 31 as described above. The restoration sliding surface 27 is slid on the lock pin 17 and can be smoothly restored to the locked state in which the lock pin 17 is locked while being pushed back to the lock pin 17.

  Therefore, in the first embodiment, if the electromagnetic solenoid 55 is operated, even if there is no collision with the pedestrian of the actual vehicle V, or even when there is a collision with the pedestrian of the actual vehicle V, thereafter, as appropriate. When the feeding portion 11 is returned to the standby position WP while the electromagnetic solenoid 55 is driven in reverse, the restoring sliding surface 27 that slides on the lock pin 17 and the torsion that biases the lock lever 20 to the locked state. The spring 31 can be used to smoothly restore the lock lever 20 to the locked state in which the lock pin 17 is locked, and the explosive actuator 35 is not used. However, it is possible to prepare for the next collision without replacing parts as much as possible.

  In addition, in the feeding device VS1 of the first embodiment, when the explosive actuator 35 of each feeding unit 10 is operated, the actuator 35 discharges combustion gas from the gas generator 37 as shown in FIGS. The piston rod 38 as a movable part is raised, the pressing surface 43a for the locking part of the head 41 at the tip is in contact with the contact surface part 25b of the locking piece part 22 of the lock lever 20, and the locking piece part 22 is The support shaft 21 is rotated in the clockwise direction so that the lock pin 17 is changed from the locked state to the unlocked state. At the same time, the feeding portion pressing surface 42a of the piston rod 38 abuts on the holding wall portion 12 of the feeding portion 11 and acts as auxiliary feeding means for the compression coil springs 18 and 18 at the beginning of feeding of the feeding portion 11. The portion 11 is pushed up, and the abutment surface portion 25 b of the lock lever 20 is pushed up by the lock pin 17 itself, so that the lock lever 20 is detached from the lock pin 17.

  Therefore, as shown in FIGS. 12 and 13, the feeding unit 11 receives the assistance of the pressing force of the actuator 35 in the initial stage of feeding, and then, due to the restoring force of the compression coil springs 18 and 18 by releasing the lock lever 20. As shown by the two-dot chain line in FIG. 13, the feeding portion 11 is quickly fed to the feeding position SP, and the entire hood panel 5 can be raised together with the hood lock device 6 and the hinge device 7.

  As described above, in the feeding device VS1 of the first embodiment, during operation, the piston rod 38 as the movable part of the explosive-type actuator 35 moves upward along the feeding direction SD of the feeding portion 11 and is locked. The lock lever 20 as the latching portion is moved to the released state to cause the restoring force of the compression spring 18 to act on the feeding portion 11, and the feeding portion 11 can be pressed in the feeding direction SD to quickly start moving. .

  Therefore, in the feeding device VS1 of the first embodiment, even when the movement of the feeding portion 11 is performed by the compression springs 18 and 18 during the operation of the explosive actuator 35, the movement of the feeding portion 11 at the initial stage of feeding is quickly performed. be able to.

  In the case of the embodiment, compared with the case where the piston rod 38 of the actuator 35 is not in contact with the feeding portion 11, the time from the start of feeding to the completion of feeding can be reduced by about 40% (5 ms to 3 ms). Was shortened).

  In particular, in the feeding device VS1 of the first embodiment, the actuator 35 moves the piston rod 38, which is a movable rod as a movable part, upward along the feeding direction SD of the feeding unit 11 during operation, and the feeding unit. The pressing distance is shortened without pressing over the entire length of the feeding distance SL from the 11 standby positions WP to the feeding position SP. The head 41 as the tip of the piston rod 38 is disposed at a position shifted from the locking portion pressing surface 43a for moving the lock lever 20 to the unlocking state and the locking portion pressing surface 43a, A feeding portion pressing surface 42a that presses the feeding portion 11, and the feeding portion pressing surface 42a is configured to release the locking lever 20 by the locking portion pressing surface 43a. The feeding portion 11 is configured to be pressed.

  Therefore, in the first embodiment, the piston rod 38 of the actuator 35 moves upward along the feeding direction SD of the feeding portion 11, and the locking lever 20 is locked by the locking portion pressing surface 43 a at the tip. The feeding unit 11 can be moved in the feeding direction SD by the feeding unit pressing surface 42a. Then, as shown in FIG. 12, the feeding portion pressing surface 42a starts to press the feeding portion 11 before the locking portion 20 is unlocked by the locking portion pressing surface 43a. The pressing force of the piston rod 38 of the actuator 35 has already acted on the feeding portion 11 immediately before the restoring force of the first time sufficiently acts on the feeding portion 11, and the timing of starting the movement of the feeding portion 11 at the beginning of feeding further. And the moving speed at the start of movement can be increased.

  As shown in FIGS. 14 to 16, the vehicle feeding device VS <b> 2 of the second embodiment is configured to include one feeding unit 10 </ b> A and a control device 101 </ b> A.

An electromagnetic solenoid 55 as a reversible actuator is provided.

  Then, when the signal from the collision detection sensor 102A is input, the control device 101A operates the actuator 35 and inputs the signal from the collision prediction sensor 103A so that the supply unit 11 can be extended quickly. In this case, the electromagnetic solenoid 55 is controlled to be operated, and the actuator 35 is operated, for example, about 30 ms after the actual collision of the vehicle V, and the electromagnetic solenoid 55 is operated before the vehicle V is collided. For example, it is performed about 100 ms before the actual collision. Even in the feeding device VS2 of the second embodiment, even if the control device 101A inputs the signal from the collision detection sensor 102A after operating the electromagnetic solenoid 55 as the reversible actuator, the explosive actuator 35 Is set not to operate.

  The knee receiving panel 68 is held by the feeding portion 11 and is disposed so as to be surrounded by an instrument panel (instrument panel) 65 below the steering column 60 in front of the driver's seat. The steering column 60 includes a main shaft 61 that fastens the steering wheel 64, a column tube 62, and a column cover 63.

  Also in the second embodiment, if the control device 101A inputs a signal from the collision sensor 102A that detects the collision of the vehicle V, the explosive actuator 35 is operated. When the actuator 35 is actuated, combustion gas is discharged from a gas generator (not shown), so that the piston rod 38 as a movable portion moves backward, and the pressing surface 43a for the locking portion of the head 41 at the tip is the locking portion. So as to abut on the abutment surface portion 25b of the locking piece portion 22 of the lock lever 20, and the locking piece portion 22 is changed from the locked state to the lock pin 17 as the locked portion to the unlocked state. Then, the support shaft 21 is rotated in the clockwise direction in FIG. At the same time, the feeding portion pressing surface 42a of the piston rod 38 abuts on the holding wall portion 12 of the feeding portion 11 and acts as auxiliary feeding means for the compression coil springs 18 and 18 at the beginning of feeding of the feeding portion 11. The portion 11 is pushed backward, and the abutment surface portion 25b of the lock lever 20 is pushed backward by the lock pin 17 itself, and the lock lever 20 is detached from the lock pin 17, so that the restoring force of the compression springs 18 and 18 The knee receiving panel 68 can be arranged at the feeding position SP together with the feeding portion 11.

  And of course, also in this feeding device VS2, when the control device 101A inputs a signal from the collision prediction sensor 103A, the electromagnetic solenoid 55 is operated to rotate the lock lever 20 in the unlocking direction. With the restoring force of 18, the knee receiving panel 68 can be disposed at the extended position SP together with the extended portion 11, and the knee K of the driver D who moves forward at the time of a frontal collision of the vehicle V can be accurately received. it can. Even in this case, as long as the electromagnetic solenoid 55 is operated, the actuator 35 is not operated even when the extending portion 11 is extended. Therefore, the actuator 35 can be reused without being replaced. .

  Incidentally, also when returning the feeding portion 11 at the feeding position SP to the standby position WP together with the knee receiving panel 68, as in the first embodiment, the energization to the electromagnetic solenoid 55 is stopped and the operating portion 56 is driven backward. On the other hand, when the feeding portion 11 is pushed forward so as to return to the standby position WP, the restoring sliding surface 27 that slides on the lock pin 17 and the urging means that urges the lock lever 20 to the locked state. Using the torsion spring 31, the lock lever 20 as the locking portion can be smoothly restored to the locked state where the lock pin 17 is locked, and the feeding portion 11 can also be restored.
