[0022] The present application provides an automatic driving vehicle collision test system.

[0023] First embodiment: please refer to Figures 1 to 3 In the first embodiment of the present application, the automatic driving vehicle collision test system comprises: a rack 1; a transverse moving mechanism 2, a fixed part of the transverse moving mechanism 2 being installed on the rack 1; a connecting mechanism 3, the connecting mechanism 3 comprising a connecting pipe 31, a fixed block 32, an elastic part 33 and a telescopic rod 34, the top of the connecting pipe 31 being installed on the moving part of the transverse moving mechanism 2, the fixed block 32 being fixedly arranged in the connecting pipe 31, the bottom of the telescopic rod 34 penetrating through the fixed block 32 and being slidingly connected, the elastic part 33 being elastically connected between the fixed block 32 and the telescopic rod 34; a collision vehicle body 4, the collision vehicle body 4 comprising a support cover 41, a sliding plate 42 and a protective cover 43, the top of the support cover 41 being fixedly connected with the bottom of the connecting pipe 31, one end of the sliding plate 42 penetrating through the support cover 41 and being slidingly connected, the protective cover 43 being fixedly arranged at the other end of the sliding plate 42, the bottom of the telescopic rod 34 abutting against the top of the sliding plate 42.

[0024] The present device is mainly applied to the U-turn test process of the automatic driving vehicle: ①, before the U-turn, the test of the oncoming vehicle, for testing whether the automatic driving vehicle can stop and wait for the oncoming vehicle to drive out of the U-turn range in advance; ②, when the U-turn, the test of the oncoming vehicle and the collision, for testing whether the automatic driving vehicle can be safely braked after the collision during the U-turn process.

[0025] In the embodiment, the rack 1 is assumed to be on the opposite lane of the turning area, and the lateral moving mechanism 2 is used to drive the whole collision vehicle body 4 to move forward along the opposite lane.

[0026] In the embodiment, the protective cover 43 is a foam structure, which increases the protection during collision.

[0027] When the connecting pipe 31 drives the support cover 41 to move: The elastic member 33 stably abuts against the sliding plate 42 under the elastic support, forms a damping structure, increases the friction between the support cover 41 and the sliding plate 42, avoids the relative sliding between the support cover 41 and the sliding plate 42 when no collision occurs, and guarantees the stability during the movement and adjustment of the equipment; When the protective cover 43 collides with the test vehicle: The lateral moving mechanism 2 can continue to drive the support cover 41 to move left relative to the sliding plate 42 through the connecting pipe 31, thereby providing a buffer distance for the reaction and shutdown of the equipment after collision, reducing the damage to the car and the test equipment during the collision test of the automatic driving car, providing effective protection effect, and prolonging the service life of the collision vehicle body 4 and the test vehicle.

[0028] Please refer to Figure 1 and Figure 2 , the tail of the rack 1 is fixedly provided with a reset plate 12, and the collision vehicle body 4 further comprises a limiting plate 44, which is fixedly arranged at one end of the sliding plate 42. When the collision vehicle body 4 is in standby state, the limiting plate 44 abuts against the reset plate 12.

[0029] After the protective cover 43 collides with the test vehicle, in the process that the lateral moving mechanism 2 drives the support cover 41 and the sliding plate 42 to move right as a whole to reset through the connecting pipe 31, the limiting plate 44 first abuts against the reset plate 12, so that the lateral moving mechanism 2 can continue to drive the connecting pipe 31 and the support cover 41 to move right relative to the sliding plate 42, so as to facilitate the automatic reset of the protective cover 43 after collision.

[0030] Please refer to Figure 2 , Figure 3 and Figure 4The transverse moving mechanism 2 comprises a mounting box 21 and a driving device 22, the mounting box 21 is mounted on the rack 1, a sliding hole 210 is formed in the bottom of the mounting box 21, the driving device 22 comprises a first driving member 221 and a transmission member 222, the first driving member 221 is fixedly arranged on the mounting box 21, the transmission member 222 is rotatably arranged in the mounting box 21, and the driving part of the first driving member 221 is connected with the transmission member 222 after penetrating through the mounting box 21. The top of the connecting pipe 31 is slidably arranged on the mounting box 21 through the sliding hole 210, and the connecting pipe 31 is connected with the moving part of the transmission member 222.

[0031] In the embodiment, the first driving member 221 is a motor structure, which provides a power source for the operation of the transmission member 222, and the transmission member 222 drives the connecting pipe 31 to move transversely for adjustment, so as to drive the whole collision vehicle body 4 to move transversely.

[0032] The connecting pipe 31 can stably move transversely for adjustment on the mounting box 21 through the sliding hole 210, so as to synchronously drive the support cover 41 to move, and the support cover 41 synchronously drives the protective cover 43 to move for adjustment through the abutting state of the telescopic rod 34 and the sliding plate 42. The first driving member 221 is used for driving the transmission member 222 to drive, and the transmission member 222 synchronously drives the whole support cover 41 and the sliding plate 42 to move transversely for adjustment through the connecting pipe 31, so as to control the whole collision vehicle body 4 to move transversely and collide with the test vehicle in the process of turning around the test vehicle.

[0033] Please refer to Figure 5 and Figure 6 An active hole 310 is formed in the connecting pipe 31; a locking cavity 300 is formed between the telescopic rod 34 and the connecting pipe 31; the top of a synchronous push block 35 is fixedly connected with the moving part of the transmission member 222, and the bottom of the synchronous push block 35 is inserted into the range of the locking cavity 300; The top of the sliding plate 42 is provided with a sliding groove 420, and the sliding groove 420 comprises a first smooth section 4201, an inclined section 4202 and a second smooth section 4203 from right to left. When the bottom of the telescopic rod 34 is located in the range of the first smooth section 4201, the top of the telescopic rod 34 is in the same plane with the top of the connecting pipe 31, and the synchronous push block 35 is locked in the range of the locking cavity 300. When the bottom of the telescopic rod 34 is located in the range of the second smooth section 4203, the top of the telescopic rod 34 is out of the horizontal range of the active hole 310, and the synchronous push block 35 is unlocked.

[0034] In the embodiment, the connecting pipe 31 is not in direct contact with the transmission member 222, and the transmission member 222 drives the connecting pipe 31 to move on the mounting box 21 for adjustment through the synchronous push block 35.

[0035] In the embodiment, the telescopic rod 34 includes two use states: In the docking state, the bottom of the telescopic rod 34 is located in the range of the first smooth section 4201, the top of the telescopic rod 34 is in the same plane as the top of the connecting pipe 31, the synchronous push block 35 is inserted into the range of the locking cavity 300, and the synchronous push block 35 can drive the support cover 41 and the sliding plate 42 to move (left or right) as a whole through the telescopic rod 34 and the connecting pipe 31 while the transmission member 222 drives the synchronous push block 35 to move. In the separated state, the bottom of the telescopic rod 34 is located in the range of the second smooth section 4203, the top of the telescopic rod 34 is retracted and out of the moving range of the synchronous push block 35, and the synchronous push block 35 can move relative to the connecting pipe 31 along the movable hole 310 and does not drive the connecting pipe 31 to move left but can drive the connecting pipe 31 to move right.

[0036] When the protective cover 43 advances and collides with the test vehicle, the protective cover 43 cannot move, but the lateral movement mechanism 2 drives the telescopic rod 34, the fixed block 32, the connecting pipe 31 and the support cover 41 in the docking state to continue to advance as a whole. During this period, the bottom of the telescopic rod 34 passes through the inclined section 4202 from the first smooth section 4201 into the second smooth section 4203, and when the telescopic rod 34 completely enters the second smooth section 4203, the elastic member 33 pushes the telescopic rod 34 to move downward, so that the top of the telescopic rod 34 moves downward and out of the pushing range of the synchronous push block 35, so that the telescopic rod 34 switches from the docking state to the separated state. The automatic separation of the connecting pipe 31 and the synchronous push block 35 when the equipment collides facilitates the collision test purpose while reducing the damage of the test vehicle and the collision vehicle body 4 in the test process.

[0037] Meanwhile, when the synchronous push block 35 moves right to reset, it can re-enter the range of the locking cavity 300 and abut against the connecting pipe 31 to drive the connecting pipe 31 to move right as a whole to reset, and during the resetting process of the connecting pipe 31, the limiting plate 44 can abut against the reset plate 12 and adaptively control the telescopic rod 34 to move upward to reset, so that the telescopic rod 34 recovers from the separated state to the docking state.

[0038] In a preferred embodiment, the transmission member 222 is a belt transmission structure, which is composed of two belt pulleys and a belt, the belt transmission connects the two belt pulleys, and any one of the belt pulleys is fixedly connected with the driving part of the first driving member 221, and the connecting pipe 31 is connected with the belt.

[0039] In another preferred embodiment, the transmission member 222 is a chain transmission structure, which is composed of two chain wheels and a chain, the chain transmission connects the two chain wheels, and any one of the chain wheels is fixedly connected with the driving part of the first driving member 221, and the connecting pipe 31 is connected with the chain.

[0040] Please refer to Figure 3 , the bottom of the telescopic rod 34 is sleeved with a rubber cover 341, and the telescopic rod 34 abuts against the sliding plate 42 through the rubber cover 341.

[0041] The rubber cover 341 abuts against the sliding plate 42 and forms a damping structure, when the protective cover 43 does not directly contact the test vehicle, the telescopic rod 34 can stably drive the sliding plate 42 to move and adjust as a whole through the rubber cover 341; and when the protective cover 43 directly contacts the test vehicle, the sliding plate 42 cannot move, but the telescopic rod 34 can continue to drive the rubber cover 341 to slide on the sliding plate 42 for adjustment, reducing damage caused by movement collision, facilitating multiple use of the equipment, and prolonging the service life of the equipment.

[0042] The friction between the telescopic rod 34 and the sliding plate 42 is increased through the rubber cover 341, so as to guarantee the stability of the support cover 41 when driving the sliding plate 42 and the protective cover 43 to move as a whole through the telescopic rod 34, and avoid loosening of the protective cover 43 relative to the support cover 41 when no collision with the test vehicle occurs.

[0043] Please refer to Figure 1 , the automatic driving vehicle collision test system further comprises a longitudinal movement mechanism 5, the longitudinal movement mechanism 5 comprises a second driving member 51, a lead screw 52 and a moving frame 53, the second driving member 51 is fixedly arranged on the rack 1, the lead screw 52 is fixedly arranged on the driving part of the second driving member 51, the moving frame 53 is threadedly connected with the lead screw 52, the moving frame 53 is slidingly installed on the rack 1, and the top of the installation box 21 is fixedly connected with the bottom of the moving frame 53.

[0044] In the embodiment, the other end of the lead screw 52 is rotationally connected with the rack 1, and the second driving member 51 is a motor structure, which provides power adjustment for the rotation adjustment of the lead screw 52, thereby facilitating the overall longitudinal movement of the moving frame 53.

[0045] The longitudinal movement mechanism 5 facilitates the overall longitudinal movement of the lateral movement mechanism 2, thereby providing support for the lane change of the collision vehicle body 4 during the overall forward movement of the collision vehicle body 4; and is used for simulating the test scene in which the collision vehicle body 4 performs and changes lanes in the opposite lane during the turning process of the automatic driving vehicle.

[0046] Meanwhile, after the collision vehicle body 4 completes a round of test, the longitudinal movement mechanism 5 can control the collision vehicle body 4 to change lanes to another lane, which on the one hand provides a scene release function for the stopping and avoiding of the automatic driving vehicle during the turning process, so as to test whether the automatic driving vehicle can continue to perform the lane change test after the front is unobstructed; and on the other hand, the collision vehicle body 4 can be moved and reset through the control of the lateral movement mechanism 2 and the longitudinal movement mechanism 5.

[0047] Please refer to Figure 1 , one side of the rack 1 is fixedly provided with two surrounding baffles 11, and a turning area is formed around the two surrounding baffles 11, and the collision vehicle body 4 is located in the shielding range of the surrounding baffles 11.

[0048] By adding the surrounding baffles 11 in the test range, the test environment in which the opposite lane in the turning range is shielded is simulated, thereby testing whether the automatic driving vehicle can avoid the suddenly coming collision vehicle body 4 in the process of turning under the premise that the opposite lane has no obvious vision.

[0049] In the preferred embodiment of the embodiment, the surrounding baffles 11 are detachably installed on the rack 1 by bolts. The surrounding baffles 11 can be installed or removed according to the needs of use, so as to meet the scene switching needs of different test environments.

[0050] The working principle of the automatic driving vehicle collision test system provided in the embodiment is as follows: Before the automatic driving vehicle turns: The first driving member 221 is started, the first driving member 221 drives the transmission member 222 to operate, the transmission member 222 drives the synchronous push block 35 to move left, and the synchronous push block 35 synchronously drives the connecting pipe 31 and the support cover 41 to move left as a whole through the telescopic rod 34 in the docking state; The support cover 41 drives the sliding plate 42 and the protective cover 43 to move left as a whole through the damping structure, so that the collision vehicle body 4 moves forward along the opposite lane and passes through the turning area; The automatic driving vehicle moves as Figure 7The shown turning range, before the automatic driving vehicle enters the turning range, test whether the automatic driving vehicle can safely stop and wait for the collision vehicle body 4 to leave the turning range; When the automatic driving vehicle turns around: When the automatic driving vehicle enters the turning range and the front part enters the opposite lane, the first driving element 221 is started, the first driving element 221 drives the synchronous push block 35 to move forward through the transmission element 222, the synchronous push block 35 drives the connection pipe 31, the support cover 41 and the sliding plate 42 to move left as a whole through the telescopic rod 34, the sliding plate 42 drives the protective cover 43 to move left and collide with the automatic driving vehicle which is turning around; After the protective cover 43 collides with the automatic driving vehicle, the protective cover 43 and the sliding plate 42 cannot move, the synchronous push block 35 drives the rubber cover 341, the connection pipe 31 and the support cover 41 to move left relative to the sliding plate 42 through the telescopic rod 34, so that the rubber cover 341 enters the second smooth section 4203 after passing through the first smooth section 4201 and the inclined section 4202 in turn; In the process that the rubber cover 341 enters the second smooth section 4203, the elastic element 33 drives the telescopic rod 34 to move down, so that the telescopic rod 34 switches from the docking state to the separated state, so that the synchronous push block 35 is separated from the connection pipe 31, the synchronous push block 35 can move out of the connection pipe 31, and the connection pipe 31 does not continue to move with the synchronous push block 35; Whether the automatic driving vehicle is safely stopped or not, the support cover 41 provides reserved space for the force retraction of the sliding plate 42 and the protective cover 43, so as to avoid the phenomenon that the automatic driving vehicle is not parked in time when colliding, and the collision vehicle body 4 is damaged by extrusion.

[0051] After the test is completed, the first driving element 221 is started again, the first driving element 221 drives the synchronous push block 35 to move right and re-enters the range of the locking cavity 300 through the transmission element 222, until the synchronous push block 35 drives the connection pipe 31 to move right, the connection pipe 31 drives the support cover 41 and the sliding plate 42 to move right as a whole when moving right; Until the limiting plate 44 abuts against the reset plate 12, the sliding plate 42 and the protective cover 43 cannot continue to move right, but the synchronous push block 35 can continue to drive the connection pipe 31 to move right, the connection pipe 31 drives the telescopic rod 34 and the rubber cover 341 to move right through the fixed block 32, and the telescopic rod 34 enters the first smooth section 4201 after passing through the second smooth section 4203 and the inclined section 4202 in turn; In the process that the rubber cover 341 enters the first smooth section 4201, the telescopic rod 34 is adaptively moved upward, the telescopic rod 34 is switched from the separated state to the docking state again, so that the synchronous push block 35 is locked with the connecting pipe 31, so that the synchronous push block 35 can subsequently drive the whole left movement of the crash car body 4 again.
