[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6This utility model provides a technical solution: a vehicle anti-collision beam strength testing device to prevent fragments from splashing, including a base 1, a motor 2, a transmission mechanism 3, an adjusting rod 4, an adjusting block 5, a connecting block 6, an upper rubber plate 7, a lower rubber plate 8, a connecting plate 9, a protective cover 10, a hydraulic rod 11, an inspection door 12, an anti-collision sponge 13, a magnetic suction plate 14, an iron plate 15, and an adhesive plate 16;

[0029] First, as attached Figure 1 As shown, the anti-collision beam whose strength needs to be tested is installed on the test vehicle. Then the vehicle is driven to the front of the base 1. A protective cover 10 is installed on the top of the base 1. A hydraulic rod 11 is installed inside the protective cover 10, so that the anti-collision beam is located in front of the hydraulic rod 11. The hydraulic rod 11 is opened, and the hydraulic rod 11 tests the anti-collision beam. A collision block is installed at the output end of the hydraulic rod 11. The hydraulic rod 11 pushes the collision block to hit the anti-collision beam. By observing the state of the anti-collision beam and the vehicle after the collision, the degree of protection of the anti-collision beam for the vehicle is tested. A maintenance door 12 is rotatably connected to the rear side of the protective cover 10. The hydraulic rod 11 can be inspected by opening the maintenance door 12.

[0030] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the base 1 has adjustment mechanisms for changing the test position on both the front and rear sides. The adjustment mechanism includes a motor 2, a transmission mechanism 3, an adjustment rod 4, and an adjustment block 5. When the motor 2 is turned on, the motor 2 drives the transmission mechanism 3 installed at its output end to run. An adjustment rod 4 is installed on the left side of the transmission mechanism 3. The transmission mechanism 3 drives the adjustment rod 4 to rotate inside the base 1. An adjustment block 5 is threadedly connected to the outside of the adjustment rod 4. The adjustment rod 4 drives the adjustment block 5 to move. The adjustment block 5 is slotted inside the base 1 and limits the adjustment block 5. A connecting block 6 is fixed to the outside of the adjustment block 5. A connecting plate 9 is integrally provided on the outside of the connecting block 6. The movement of the adjustment block 5 drives the connecting plate 9 to move. A protective cover 10 is installed above the connecting plate 9. The protective cover 10 drives the hydraulic rod 11 inside it to move and adjust the test position. The front and rear of the adjustment rod 4 are symmetrically distributed to ensure stability during movement.

[0031] As attached Figure 3 As shown, the adjustment mechanism also includes a connecting block 6, an upper rubber plate 7, and a lower rubber plate 8. When the adjusting block 5 moves, the adjusting block 5 drives the connecting block 6 fixed on its outer side to move. The connecting block 6 slides between the upper rubber plate 7 and the lower rubber plate 8. Since the longitudinal sections of the left and right ends of the connecting block 6 are triangular, the connecting block 6 can always maintain a tight fit with the upper rubber plate 7 and the lower rubber plate 8. The upper rubber plate 7 and the lower rubber plate 8 are tightly fitted to each other. The upper rubber plate 7 is fixed on the upper inner side of the base 1, and the lower rubber plate 8 is fixed on the lower inner side of the base 1, which protects the adjusting rod 4 and prevents fragments from splashing onto the adjusting rod 4 and causing the adjusting rod 4 to jam.

[0032] As attached Figure 1 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the front of the protective cover 10 is provided with a buffer mechanism to prevent fragments from splashing. The buffer mechanism includes a shock-absorbing sponge 13, a magnetic suction plate 14, an iron plate 15, and an adhesive plate 16. When the hydraulic rod 11 drives the collision block to hit the anti-collision beam, the anti-collision beam is damaged. The front of the iron plate 15 is attached to the adhesive plate 16, and the splashed fragments are stuck to the adhesive plate 16 to prevent the fragments from damaging the hydraulic rod 11. The protective cover 10 can also protect the hydraulic rod 11. The shock-absorbing sponge 13 is fixed to the front of the protective cover 10 to buffer the impact force of the fragments. When the adhesive plate 16 needs to be replaced, the front of the shock-absorbing sponge 13 is fixed with a magnetic suction plate 14, and the front of the magnetic suction plate 14 is magnetically connected to the iron plate 15. Pulling the iron plate 15 outward will disengage the iron plate 15 from the magnetic suction plate 14, and the adhesive plate 16 attached to the iron plate 15 can be peeled off. The back of the adhesive plate 16 can be connected to the iron plate 15 with adhesive.

[0033] This is the entire working process of the automotive crash beam strength testing device that prevents debris from flying. Any content not described in detail in this specification is prior art known to those skilled in the art.
