The mounting plate 215 is located outside the vehicle frame 110. A protective plate 219 is sleeved on the outer side of the mounting plate 215 in a limited sliding manner. The spring steel plate 212 weakens the inertia generated by vehicle impact.
[0027] Please refer to Figure 4 and Figure 5 , the buffer component 210 further includes fixing columns 211. The fixing columns 211 are respectively fixedly installed on both sides of the vehicle frame 110. The spring steel plate 212 is connected to the fixing columns 211 in a limited way. The upper and lower ends of the spring steel plate 212 are respectively connected to the upper and lower sides of the mounting plate 215. The middle part of the spring steel plate 212 is connected to the fixing columns 211 in a limited way through a U-shaped bolt and a limiting plate.
[0028] Both ends of the spring steel plate 212 are respectively hinged with an upper connection frame 213 and a lower connection frame 214. The other sides of the upper connection frame 213 and the lower connection frame 214 are fixedly connected to the mounting plate 215. A buffer plate 216 is arranged on the side of the mounting plate 215 away from the spring steel plate 212. The buffer plate 216 is connected to the mounting plate 215 in a limited way through a spring damper 217. Both ends of the spring damper 217 are respectively hinged with a connection seat 218.

The cross-section of the protective plate 219 is U-shaped, and the inner wall of the protective plate 219 is connected to the outer wall of the mounting plate 215 in a limited sliding manner.
[0029] Please refer to Figure 2 and Figure 3, an anti-collision buffer vehicle, anti-collision components 120 are respectively arranged at both ends inside the vehicle frame 110.

A limit mounting block 125 is arranged at the bottom of the top plate 121. Both sides of the limit mounting block 125 are in limit sliding connection with the inner wall of the vehicle frame 110. A hydraulic cylinder 122 is arranged between the limit mounting block 125 and the top plate 121. A positioning block 126 is fixedly installed at the bottom of the limit mounting block 125.

The limit mounting block 125 is inclined towards the head side of the vehicle body 100. When the tail of the vehicle body 100 is impacted, the positioning block 126 will rub against the ground to reduce the sliding distance of the positioning block 126 and improve braking. The positioning block 126 can be replaced with brake pads, etc.
[0030] Working principle: When the vehicle body 100 is parked, control the hydraulic cylinder 122 to drive the limit mounting block 125 and the positioning block 126 to move downward, so that the positioning block 126 is close to the ground. When the vehicle impacts the protection plate 219, the protection plate 219 will quickly squeeze the buffer plate 216, causing the buffer plate 216 to approach the mounting plate 215, and the impact is weakened through the spring damper 217. At the same time, the impact force will continue to be transmitted to the vehicle body 100 through the mounting plate 215, and is secondarily weakened by the spring steel plate 212 to reduce the external impact force. At the same time, the positioning block 126 is close to the ground, increasing the friction force and effectively preventing the vehicle body 100 from displacing.
