[0022] Example 1

[0023] Refer to the attached Figure 1 , 2The present application provides an auxiliary test device for an intelligent high beam auxiliary system, comprising a simulated vehicle 1, a test track 3 and a trigger device 2. The test track 3 is used to place the vehicle to be tested and the simulated vehicle 1. The simulated vehicle 1 is used to simulate a real vehicle. The simulated vehicle 1 comprises a front panel 4, a rear panel 5, a side panel 6 and a transmission rod 7. The simulated vehicle 1 has a small mass. The front panel 4 and the rear panel 5 are hinged to the test track 3. The front panel 4 and the rear panel 5 can be rotated and attached to the test track. The front panel 4 and the rear panel 5 are connected by the transmission rod 7. When the front panel 4 rotates, the rear panel 5 is driven to rotate together. The side panel 6 comprises an inclined rod 8 and a flexible shield 9. The flexible shield 9 can be stored, and the inclined rod 8 can support the diagonal of the shield. The inclined rod 8 is hinged to the front panel 4. The inclined rod 8 can rotate relative to the front panel 4 at a preset angle, and when the front panel 4 rotates, the inclined rod 8 is driven to rotate. When the front panel 4 rotates to a vertical state, the tilting rod 8 rotates to a tilted state, and the flexible mask is fixedly connected to the tilting rod 8, so that the tilting rod 8 supports the flexible mask 9. The lower end of the flexible mask is connected to the test track 3, and the side is connected to the front panel 4. When the front panel 4 is in a vertical state, the flexible mask is unfolded. The front panel 4 and the rear panel 5 are both connected to the test track 3 through a first spring 10. The test track 3 is provided with a groove 11. The first spring 10 is used to drive the front panel 4 and the rear panel 5 to rotate into the groove 11. Under the action of the first spring 10, the front panel 4 and the rear panel 5 have a tendency to rotate into the groove 11. The trigger device 2 includes a motor 12, a stopper 13, a pull rope 14, a second spring 15, a third spring 16 and a pedal 17. The second spring 15 connects the pedal 17 and the test track 3. The pedal 17 is hinged to the test track 3 at one end. The other end of the pedal 17 is connected to the pull rope 14. The pull rope 14 is connected to the stopper 13. The front panel 4 is provided with a slot 18 that cooperates with the stopper 13. The third spring 16 is used to drive the stopper 13 to insert into the slot 18. The motor 12 is connected to the front panel 4. When the motor 12 is working, it drives the front panel 4 to rotate to a vertical state and compresses the first spring 10 to store elastic potential energy. The stopper 13 moves and inserts into the slot 18 under the elastic force of the third spring 16. After the stopper 13 is inserted into the slot 18, the front panel 4 is clamped, thereby fixing the position of the front panel 4. One end of the pedal 17 tilts upward under the action of the second spring 15. When the vehicle to be tested moves above the pedal 17, the vehicle to be tested presses the pedal 17 downward, and the pedal 17 pulls the limit block 13 through the pull rope 14, so that the limit block 13 is disengaged from the slot 18. At this time, the front panel 4 rotates into the groove 11 under the action of the first spring 10.When the present invention is testing, when the vehicle to be tested moves to the position of the pedal 17, the pedal 17 is pressed downward by the vehicle to be tested to trigger the limit block 13, so that the limit block 13 releases the restriction on the front panel 4, and the front panel 4 rotates so that the front panel 4, the rear panel 5 and the side panel 6 are stored in the groove 11. The vehicle to be tested can move directly on the test track 3 to prevent the vehicle device to be tested from colliding with the simulation vehicle measurement.

[0024] Specifically, one end of the transmission rod 7 is hinged to the front panel 4, and the other end is hinged to the rear panel 5, and the line connecting the rotation centers of the front panel 4 and the rear panel 5 is parallel to the transmission rod 7. The front panel 4, the rear panel 5 and the transmission rod 7 form the sides of a parallelogram, and when the front panel 4 rotates, the rear panel 5 is driven to rotate together.

[0025] Specifically, a base 19 is provided at the bottom of the simulation vehicle 1, and the base 19 is fixed to the test track 3. The base 19 is made of a material different from that of the test track 3, and is more durable. The pedal 17 is hinged to the base 19 at a side away from the simulation vehicle 1, and the movable end of the pedal 17 is connected to the pull rope 14. When the movable end of the pedal 17 is pressed downward, the pull rope 14 is released, so that the third spring 16 can push the limit block 13 out of the slot 18. The base 19 is provided with a slide groove 20 for accommodating the limit block 13, which is convenient for the sliding of the limit block 13. The limit block 13 is J-shaped, and the long end of the limit block 13 is connected to the pull rope 14. When the limit block 13 moves, the short end is inserted into the slot 18.

[0026] Example 2

[0027] See attached Figure 3 The difference between this embodiment and the first embodiment is that the base 19 is provided with a plurality of air holes 21 and an air cavity 22, the air cavity 22 is connected to the upper surface of the base 19 through the air holes 21, and the air cavity 22 is connected to an air pump 23. When the air pump is working, a negative pressure is formed in the air cavity 22, and the air above the base 19 is sucked away through the air holes 21. When the front panel 4 rotates backward and adheres to the top of the base 19, the air can be quickly discharged to prevent the air from hindering the rotation of the front panel 4.

[0028] Example 3

[0029] See attached Figure 4The difference between this embodiment and embodiment 1 or 2 is that a drum 24 is provided on the side of the base 19, and the drum 24 is conical. The intersection of the extension lines of the busbars on both sides of the drum 24 coincides with the rotation axis of the front panel 4. The flexible mask is connected to the drum 24. When the drum 24 rotates, the flexible mask is rolled up, and the flexible mask 9 can be rolled up smoothly. The inclined rod 8 includes a rod body 25, a ring 26, a first slider 27 and a second slider 28. When the drum 24 rotates, the inclined rod 8 is rolled up onto the drum 24, and the inclined rod 8 is parallel to the busbar of the drum 24. The first slider 27 and the second slider 28 are slidably connected to the ring 26. The first slider 27 is connected to the inclined rod 8, and the second slider 28 is hinged to the front panel 4. The inclined rod 8 can be rolled up on the drum 24 and can also be rotated relative to the front panel 4, thereby supporting the flexible mask.

[0030] Specifically, the ring 26 includes a front ring 29 and a rear ring 30, and the front ring 29 and the rear ring 30 are fixedly connected. The first slider 27 is slidably connected to the front ring 29, and the second slider 28 is slidably connected to the rear ring 30. The first slider 27 can slide around the front ring 29, and the second slider 28 can slide around the rear ring 30. This can avoid the first slider 27 and the second slider 28 from interfering with each other, ensuring that the reel 24 can effectively reel in the inclined rod 8 and the flexible mask 9, and can ensure that the inclined rod 8 can support the flexible mask 9.

[0031] Specifically, the reel 24 is provided with a fourth spring 31 , one end of the fourth spring 31 is connected to the reel 24 , and the other end is connected to the base 19 , and the fourth spring 31 is used to drive the reel 24 to rotate to retract the flexible cover, and the fourth spring 31 is used to drive the reel 24 to rotate.

[0032] Specifically, the first spring 10 and the fourth spring 31 are spiral springs, which provide torsion to drive the front panel 4, the rear panel 5 and the reel 24 to rotate, and the second spring 15 and the third spring 16 are helical springs, which provide supporting force to drive the pedal 17 and the limit block 13 to move and reset.

[0033] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
