[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 3 , an anti-collision energy-absorbing vehicle body reinforcement plate structure, including a rocker plate 1, a reinforcement plate 2 is fixedly installed at the bottom end of the rocker plate 1, a reinforcement shell 3 is fixedly installed below the reinforcement plate 2, and an anti-collision mechanism 4 is provided at the bottom end of the reinforcement shell 3; the anti-collision mechanism 4 includes a force-bearing plate 401, the force-bearing plate 401 is slidably connected to the inside of the reinforcement shell 3, and a resistance plate 402 is fixedly installed at one end of the force-bearing plate 401 that penetrates into the reinforcement shell 3, and an anti-collision block 403 is embedded at the top of the resistance plate 402, and an anti-collision pad 404 is fixedly installed at the top of the anti-collision block 403. A damping spring 405 is embedded on one side of the anti-collision block 403 at the top of the touch plate 402, and a support rod 406 is fixedly installed on the bottom end of the damping spring 405. The support rod 406 passes through one end of the contact plate 402 and is fixedly installed with a limit block 407. The limit block 407 is embedded with a rubber pad 408 on the outer wall facing the contact plate 402. The anti-collision pad 404 is bonded and connected to the anti-collision block 403, and the anti-collision pad 404 fits tightly with the reinforcement shell 3. The rubber pad 408 is bonded and connected to the limit block 407, and the rubber pad 408 fits tightly with the contact plate 402.

[0028] By adopting the above technical solution, when being hit, the force-bearing plate 401 drives the contact plate 402 to slide along the reinforcing shell 3 when being hit, and the anti-collision block 403 fixed to the contact plate 402 avoids excessive impact and noise through the anti-collision pad 404. At the same time, the damping spring 405 is fixed to the contact plate 402 through the support rod 406 and the limit block 407, which plays the role of energy dissipation and shock absorption when being hit, thereby playing an anti-collision effect, and at the same time cooperates with the rubber pad 408 to avoid noise due to collision.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the axial outer wall of the force-bearing plate 401 is provided with a resistance mechanism 5, which includes a sleeve 501, which is embedded in the axial outer wall of the force-bearing plate 401, and a rod 502 is passed through the interior of the sleeve 501, and the rod 502 is located on the outer wall of one end of the sleeve 501 and is fixedly installed with a limit ring 503. The resistance mechanism 5 also includes a sealing gasket 504, which is embedded in the bottom end of the rod 502, and a telescopic spring 505 is embedded at the lower part of the interior of the sleeve 501. A sliding structure is formed between the sleeve 501 and the limit ring 503, and the sleeve 501 is equidistantly and evenly distributed about the outer wall of the force-bearing plate 401. The rod 502 forms an elastic structure with the sleeve 501 through the telescopic spring 505, and the rod 502 is bonded to the sealing gasket 504.

[0030] By adopting the above technical solution, when subjected to force, the penetration rod 502 is elastically pushed out of the sleeve 501 through the telescopic spring 505, and is pressed between the force-bearing plate 401 and the reinforcing plate 2, thereby achieving an anti-collision effect. At the same time, it cooperates with the limit ring 503 to prevent the penetration rod 502 from excessively penetrating and detaching. At the same time, the air tightness is maintained through the sealing gasket 504. When the penetration rod 502 penetrates the sleeve 501, a piston motion is formed, thereby improving the stability of the sliding process.

[0031] Working principle: The threshold plate 1 improves the hardness and strength through the welded reinforcement plate 2, and at the same time strengthens the load-bearing plate 401 that is slidably connected inside the reinforcement shell 3, and the anti-collision block 403 and the anti-collision pad 404 fixed by the contact plate 402 to avoid noise when hit. The damping spring 405 is installed on the load-bearing plate 401 through the support rod 406 and the limit block 407, and has the effect of energy dissipation and shock absorption when hit, and cooperates with the rubber pad 408 to avoid collision and noise when under force. The sleeve 501 and the penetration rod 502 form a telescopic rod, and the telescopic spring 505 elastically pushes it to further prevent collision. The limit ring 503 prevents the penetration rod 502 from passing through the sleeve 501, and the sealing is maintained by the sealing pad 504, so that the sleeve 501 and the penetration rod 502 form a piston motion, thereby further improving the stability when under force.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
