In the horizontal direction, vibration drives the connecting rod to rotate around the rotating shaft a, causing the fixed ring to move relative to it, and spring a to extend and retract to absorb the horizontal impact force. In the vertical direction, after the chassis floor plate is compressed, the top plate squeezes spring b, and spring b deforms to buffer the vertical vibration. The limiting post can prevent spring b from being over-compressed. The two work together to effectively reduce the impact of bumps on the chassis floor plate.

In this utility model, the mounting bracket, X-shaped diagonal brace, horizontal support rod and vertical support rod work together to effectively disperse the impact force of the collision. When a collision occurs, the impact force is first transmitted to the bumper, and then transmitted to the X-shaped diagonal brace through the mounting bracket. The diagonal brace disperses the force to both sides. At the same time, the horizontal support rod bears the lateral force and the vertical support rod bears the vertical force. The multiple components work together to evenly transmit the impact force to the vehicle frame assembly, reducing the damage to the vehicle frame assembly caused by the collision.

[0030] Working principle: The vehicle frame assembly 1 includes two frames 11, which are placed horizontally opposite each other. Both frames are fixedly connected to the inner side of the fixing plate 16, and anti-collision components 3 are fixedly connected to both ends. Two fixing rods 17 are fixedly connected to the outer sides of each frame. A transmission rod 13 is fixedly connected to the end of each fixing rod 17. A wheel 5 is fixedly connected to the outer end of the transmission rod 13, and an axle 12 is fixedly connected to its inner end. A power transmission device 14 is fixedly connected to the outer middle of the axle 12. A drive rod 15 is fixedly connected to the inside of the power transmission device 14. The bottom of the drive rod 15 is rotatably connected to the top of the fixing plate 16, and another power transmission device 14 is fixedly connected to its end. The other end of the axle 12 is fixedly connected to another transmission rod 13. The outer side of this transmission rod 13 is fixedly connected to... The other wheel 5 is fixedly connected. The two power transmission units 14 are fixedly connected together by the drive rod 15. When the vehicle is running, the power is transmitted to the power transmission unit 14 through the drive rod 15. The power transmission unit 14 drives the axle 12 to rotate. The axle 12 transmits the power to the wheel 5 through the transmission rod 13, thereby driving the wheel 5 to rotate and providing the power basis for the vehicle to move. In the shock absorption assembly 2, the inside of the fixing ring 21 is fixedly connected to the inside of the frame assembly 1. The top of the outer side is fixedly connected to two horizontal fixing bolts 22. The two horizontal fixing bolts 22 are fixedly connected to the rotating shaft a24 on the opposite side. The middle of the rotating shaft a24 is rotatably connected to the connecting rod 25. The end of the connecting rod 25 is rotatably connected to the connecting rod 25. The upper side is fixedly connected to the rotating shaft. b26, both ends of the rotating shaft b26 are fixedly connected to vertical fixing bolts 27. The tops of the two vertical fixing bolts 27 are fixedly connected to the chassis base plate 4. At the same time, two extension plates 28 are fixedly connected to the inside of the two frames 11 on opposite horizontal sides. The top of the extension plate 28 is fixedly connected to the spring b210. The top of the spring b210 is fixedly connected to the top plate 29. The top of the top plate 29 is fixedly connected to the bottom of the chassis base plate 4, and the bottom is fixedly connected to the limiting post 211. The two ends of the shock absorber are fixedly connected to the opposite horizontal sides of the frame 11. Two fixing rings 21 are fixedly connected to the outside of the shock absorber. The spring a23 is fixedly connected to the opposite horizontal sides of the two fixing rings 21, and the top is fixedly connected to the bottom of the two horizontal fixing bolts 22. When the vehicle encounters a bump... When the vehicle is shaken or vibrated, the chassis base plate 4 is subjected to downward pressure, which is transmitted to the vertical fixing bolt 27, causing the rotating shaft b26 to move downward, and then causing the connecting rod 25 to rotate around the rotating shaft a24. At this time, the spring a23 between the two fixing rings 21 deforms due to the relative movement of the fixing rings 21, buffering the horizontal impact force. The pressure of the chassis base plate 4 is transmitted to the top plate 29, and the top plate 29 compresses the spring b210. The spring b210 deforms to buffer the vertical impact force. The limiting post 211 restricts the top plate 29 from moving downward too much, avoiding excessive compression of the spring b210. The extension plate 28 provides stable support for the spring b210 and the top plate 29. Through the above-mentioned multi-directional buffering effect, the shock absorption assembly 2 achieves effective shock absorption of the vehicle.

Two mounting brackets 32 are fixedly connected internally, and the inner side of the mounting brackets 32 is fixedly connected to the frame 11. Two "X"-shaped diagonal braces 33 are fixedly connected internally to the bumper 31. A horizontal support rod 34 is fixedly connected to the outer side of the mounting brackets 32, and the outer ends of the horizontal support rod 34 are fixedly connected to the two inner sides of the bumper 31. A vertical support rod 35 is fixedly connected to the middle of the horizontal support rod 35, and the upper and lower ends of the vertical support rod 35 are fixedly connected to the bumper 31. When the vehicle is involved in a collision, the bumper 31 is the first to contact the object. Its smooth chamfered design reduces local stress concentration during the collision. The impact force generated by the collision is transmitted to the mounting bracket 32, diagonal brace 33, horizontal strut 34 and vertical strut 35 inside the bumper 31. Among them, the "X"-shaped diagonal brace 33 enhances the structural stability, while the horizontal strut 34 and vertical strut 35 further disperse the impact force. Finally, these forces are transmitted to the frame 11 through the mounting bracket 32, achieving effective buffering and dispersion of the collision force and playing a role in collision protection.
