Description

Technical Field

[0001] The present invention relates to the field of automobiles, and in particular to an automobile anti-collision beam detection device. Background Art

[0002] The anti-collision beam is a device used to reduce the impact energy absorbed by the vehicle when it is hit by a collision. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at low speeds, minimizing the damage to the longitudinal beams of the vehicle body caused by the impact force, thereby playing a protective role for the vehicle. It can be seen that the anti-collision beam needs the joint action of the main beam and the energy absorption box to absorb the collision energy to the maximum extent. When an accident occurs, the energy absorption box does not deform, but the main beam is directly crushed, indicating that the energy absorption box does not play its due energy absorption role and the main beam is not strong enough. Therefore, it is necessary to conduct a bending resistance test before the anti-collision beam is installed on the vehicle body for use.

[0003] The applicant has found that during the current inspection, the operator first places the anti-collision beam for inspection, and after the inspection is completed, takes out the anti-collision beam and then puts in the next anti-collision beam, which is not efficient.

[0041] The pressing block 5 is located directly above the rotating column 6 , and the upper surface of the pressing block 5 is fixedly connected to the pull rope of the winch 3 .

[0042] When the first gear 11 is in the state of being rotated, the first gear 12 is rotated to the state of being rotated, and the first gear 13 is rotated to the state of being rotated.

[0043] As an implementation method, Figure 4 As shown, the driving unit includes a third motor 21 fixed to the outer surface of one of the side panels 1 and a gear 22 fixed to the output shaft of the third motor 21. The gear 22 meshes with a rack provided on the side surface of the corresponding end of the rotating column 6. Here, the rotating column 6 is driven to rotate by the third motor 21 and the gear 22.

[0044] As an implementation method, Figure 2 、 Figure 3 As shown, the fixing portion includes:

[0045] Threaded holes 24 are provided in the left and right side walls at both ends of the groove 7. The threaded holes 24 are arranged at an angle and pass through the side surface of the rotating column 6.

[0046] A supporting rod 16 threadedly connected to the threaded hole 24 and a rectangular rod 17 fixed to the top of the supporting rod 16;

[0047] A driving block 18 having a rectangular hole 19 on its bottom end surface, wherein the rectangular rod 17 matches the rectangular hole 19 and is located in the rectangular hole 19;

[0048] The second motor 20 is fixed to the side surface of the rotating column 6 through a fixing member, and the output shaft of the second motor 20 is fixedly connected to the top end of the driving block 18.

[0049] Here, when the energy absorption box needs to be clamped by the supporting rod 16, the second motors 20 on both sides of the energy absorption box are started at the same time, and the supporting rod 16 is driven to rotate in the threaded hole 24 through the driving block 18, so that the supporting rod 16 gradually clamps the energy absorption box; if the energy absorption box needs to be loosened, it is only necessary to rotate the second motor 20 in the opposite direction.

[0050] As an implementation method, Figure 2 、 Figure 3 、 Figure 4 As shown, it also includes:

[0051] An inner cavity 8 is provided in the rotating column 6, and the inner cavity 8 is connected to the groove 7 through a connecting groove 13 at the bottom of the groove 7, and the groove 7 and the connecting groove 13 both pass through one end surface of the rotating column 6;

[0052] A drive rod 10 and a fourth motor 23, wherein one end of the drive rod 10 is rotatably connected to one end of the inner cavity 8; the other end of the drive rod 10 extends to the outside of one end of the rotating column 6, and this end of the drive rod 10 is fixedly connected to the output shaft of the fourth motor 23, and the fourth motor 23 is fixed to the side plate 1; the central axis of the drive rod 10 coincides with the central axis of the rotating column 6;
