[0033] Working principle: When the bumper 26 is hit during driving, it moves inwards. At this time, the buffer spring 17 performs the first unloading of the impact force. At the same time, the sliding rod 15 slides into the connecting rod 1. When the bumper 26 contacts the sponge block 16 and squeezes it, it unloads the force for the second time and spreads the force to the entire connecting rod 1, so that the impact force is dispersed. Then the force is transmitted to the threaded column 2. At this time, the telescopic rod 3 slides into the threaded column 2 under the impact force. When sliding, the sliding block 10 fixed on the telescopic rod 3 pushes the sliding column 11 to slide inward, and the fixed As the limiting block 12 on the telescopic rod 3 starts to slide, it compresses the spring block 13, and the spring block 13 unloads the force for the third time. As the sliding column 11 slides, the liquid contained in the rear side of the sliding column 11 is squeezed to swim to the front side along the slide groove on the surface of the sliding column 11. As the liquid passes through the cavity inside the hollow block 9, it presses the sliding block 8, so that the sealing block 7 starts to compress the buffer spring 6. The buffer spring 6 gradually eliminates the impact force as it is compressed. After it is completely dissipated, it will compress the liquid to return to its original position. At this time, the telescopic rod 3 returns to its original position. The hydraulic buffer can more effectively absorb and disperse the collision energy, reduce the impact force on the vehicle body, and thus provide better protection. The hydraulic buffer can better control the vibration of the vehicle body after the collision, and reduce the subsequent impact of the vehicle body and passengers.

[0034] To replace the bumper 26 after a collision, one only needs to manually press the clamp block 21 to expand it to both sides, and then drag the bumper 26 outward to complete the disassembly. When installing, one only needs to align the clamp block 21 with the cylinder 20 and push it toward it. When the clamp block 21 is subjected to the pressure of the cylinder 20, the clamp block 21 expands to both sides through the spring column 22 until the bumper 26 fits with the fixing pile 18, and the installation is completed.
