[0033] Embodiment 2

[0034] With reference to Figure 1 , Figure 2 , Figure 3 and Figure 4For the second embodiment of the utility model, this embodiment is based on the previous embodiment, the dismounting mechanism 3 includes the second mounting block 304 which is fixedly connected to the damper 210 and the other end of the spring 209, the outer surface of the second mounting block 304 is screw-connected with the second bolt 305.

[0035] The specific dismounting mechanism 3 further includes the first mounting block 302 which is fixedly connected to the inner side of the mounting plate 201, the outer surface of the first mounting block 302 is screw-connected with the first bolt 303, the outer surface of the first bolt 303 is screw-connected to the inner side of the fixed anti-collision frame 1, the outer surface of the fixed anti-collision frame 1 is screw-connected with the positioning bolt 301, and the positioning bolt 301 is screw-connected with the road surface.

[0036] Further, the anti-collision device adopts a modular and detachable design, and the components are connected through bolts. When the components such as the anti-collision shell 204, the buffer pad 212 or the air bag 211 are deformed or damaged in the impact, they can be conveniently and quickly disassembled and replaced individually without the need to replace the entire device. This not only improves the maintenance efficiency, but also greatly reduces the maintenance cost, so that the anti-collision device is more economical and practical in long-term use.

[0037] Working principle: when installing the anti-collision device, first, the fixed anti-collision frame 1 is firmly fixed on the ground through the positioning bolt 301 to ensure the stability of the entire device. Then, the anti-collision shell 204 is tightly attached to the second mounting block 304 using the second bolt 305, so that the anti-collision shell 204 can be stably installed on the outer surface of the second mounting block 304. After that, the buffer pad 212 is slid along a specific track into the inner wall of the anti-collision shell 204 to ensure the fit between them. Then, the first mounting block 302 is fixed to the inner side of the fixed anti-collision frame 1 using the first bolt 303, so that the installation of the mounting plate 201, the buffer pad 212 and the air bag 211 is completed. This detachable design greatly facilitates the subsequent individual disassembly and replacement of the deformed or damaged modules.

[0038] After the installation is completed, the gas is filled into the inflation pipeline 205 through the one-way inflation valve 202, and since the inflation pipeline 205 is connected with the plurality of air bags 211 through the pipeline, the gas can be evenly filled into each air bag 211, so that the air bag 211 is filled with gas, and the air bag 211 has good buffering performance. When the vehicle collides with the anti-collision device, the rubber pad 203 on the outer surface of the anti-collision shell 204 is first contacted by the vehicle. The plurality of grooves formed on the surface of the rubber pad 203 can increase the contact area with the vehicle, and at the same time, the impact force is dispersed, the vehicle is first buffered, and the initial impact force of the impact is reduced. Then, the impact force is transmitted to the anti-collision shell 204, and is conducted to the spring 209 and the damper 210 through the second mounting block 304. The spring 209 and the damper 210 play a role, and the vehicle is secondly buffered, and they can convert the kinetic energy generated by the impact into elastic potential energy and heat energy, and further reduce the impact force. At the same time, the buffer pad 212 and the internal air bag 211 are deformed under the action of the impact force, and absorb and disperse the remaining energy, and the vehicle is buffered for many times, so that the impact force suffered by the vehicle is effectively reduced, and the safety of the vehicle and the people in the vehicle is protected.
