For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figure 1 and Figure 2This application provides a locomotive backrest elastic structure, including a base 1 and a backrest body 2. An adjustment mechanism 3 for adjusting the angle and height of the backrest body 2 is provided on the upper part of the base 1. An elastic support mechanism 4 is provided on the upper part of the base 1. The adjustment mechanism 3 includes a fixed plate 301, a slider 302 and a connecting roller 306. The fixed plate 301 is fixedly installed on the upper surface of the base 1. The slider 302 is slidably connected to the inner wall surface of the fixed plate 301. The connecting roller 306 is installed on the upper part of the base 1. The backrest body 2 is installed on the upper part of the base 1. By adjusting the adjustment mechanism 3, the slider 302 can be moved up and down along the inner wall of the fixed plate 301 by loosening the fastening bolts. After adjusting the slider 302 to a suitable height position according to the user's height and comfort needs, the fastening bolts are tightened again to fix the slider 302 on the fixed plate 301, thereby realizing the height adjustment of the backrest body 2. Then, the slide bar 309 is pulled outward, causing the mounting plate 308 to move and compressing the spring 307. Simultaneously, the limiting block 310 on the mounting plate 308 slides against the inner wall of the rotating block 305. After the limiting block 310 disengages from the rotating block 305, the backrest body 2 is pulled, causing the rotating block 305 to rotate and the connecting roller 306 to rotate. This adjusts the angle of the mounting frame 401 on the connecting roller 306, thus adjusting the angle of the backrest body 2. After adjusting to the appropriate angle, the slide bar 309 is released. Under the elastic force of the spring 307, the mounting plate 308 causes the slide bar 309 and the limiting block 310 to reset. The limiting block 310 then again limits the rotation of the rotating block 305, preventing it from rotating arbitrarily. Through the elastic support mechanism 4, when encountering bumps during locomotive operation, the impact force is first transmitted to the backrest body 2, which then transmits the force to the buffer pad 403, which in turn transmits the force to the elastic rubber block 402. The 402 elastic rubber block has good elasticity and can effectively absorb and disperse these impacts, reduce vibrations to the rider's back, and provide a comfortable support experience for the rider.

[0033] Reference Figure 2 , Figure 3 and Figure 4 In one aspect of this embodiment, both the fixing plate 301 and the slider 302 have positioning holes 303 on one side, and fastening bolts are threaded onto the inner wall surface of the positioning holes 303. The slider 302 is fixedly installed on one side of the inner wall of the fixing plate 301 by the fastening bolts.

[0034] A mounting box 304 is fixedly installed on one side of the slider 302. Rotating blocks 305 are rotatably connected to both sides of the inner wall of the mounting box 304. A connecting roller 306 is fixedly installed on one end of the rotating block 305.

[0035] A spring 307 is fixedly installed on one side of the inner wall of the mounting box 304. A mounting plate 308 is fixedly installed on one end of the spring 307. A slide rod 309 is fixedly installed on one side of the mounting plate 308. The slide rod 309 passes through one side of the mounting box 304.

[0036] On the other side of the mounting plate 308, a limiting block 310 is fixedly installed. The limiting block 310 is slidably connected to the inner wall surface of the rotating block 305. By loosening the fastening bolts, the slider 302 can be moved up and down along the inner wall of the fixed plate 301. After adjusting the slider 302 to a suitable height position according to the user's height and comfort needs, the fastening bolts are tightened again to fix the slider 302 on the fixed plate 301, thereby realizing the height adjustment of the backrest body 2. Then, pull the slide bar 309 outward, which moves the mounting plate 308 and compresses the spring 307. At the same time, the limiting block 310 on the mounting plate 308 slides on the inner wall of the rotating block 305. After the limiting block 310 disengages from the rotating block 305, pull the backrest body 2 to make the rotating block 305 drive the connecting roller 306 to rotate, thereby adjusting the angle of the mounting frame 401 on the connecting roller 306 and adjusting the angle of the backrest body 2. After adjusting to the appropriate angle, release the slide bar 309. Under the elastic force of the spring 307, the mounting plate 308 drives the slide bar 309 and the limiting block 310 to reset. The limiting block 310 then resumes its limiting function on the rotating block 305 to prevent it from rotating arbitrarily.

[0037] Reference Figure 4 and Figure 5 In one aspect of this embodiment, a mounting frame 401 is fixedly mounted on the upper surface of the connecting roller 306. An elastic rubber block 402 is fixedly mounted on one side of the inner wall of the mounting frame 401. A buffer pad 403 is fixedly mounted on one end of the elastic rubber block 402. The backrest body 2 is fixedly mounted on one side of the buffer pad 403. When the motorcycle encounters bumps during operation, the impact force is first transmitted to the backrest body 2, which then transmits the force to the buffer pad 403, which in turn transmits the force to the elastic rubber block 402. The elastic rubber block 402 has good elasticity and can effectively absorb and disperse these impact forces, reducing vibration to the rider's back and providing a comfortable support experience for the rider.

[0038] All electrical devices in this plan are powered by an external power source.

[0039] Working principle: When using this device, first install the device on the locomotive through the mounting hole opened above the base 1, loosen the fastening bolts, move the slider 302 up and down along the inner wall of the fixing plate 301, adjust the slider 302 to a suitable height position according to the user's height and comfort needs, and then tighten the fastening bolts again to fix the slider 302 on the fixing plate 301, thereby realizing the height adjustment of the backrest body 2. Then, the slide bar 309 is pulled outward, causing the mounting plate 308 to move and compressing the spring 307. Simultaneously, the limiting block 310 on the mounting plate 308 slides against the inner wall of the rotating block 305. After the limiting block 310 disengages from the rotating block 305, the backrest body 2 is pulled, causing the rotating block 305 to rotate the connecting roller 306. This adjusts the angle of the mounting frame 401 on the connecting roller 306, thus adjusting the angle of the backrest body 2. Once the appropriate angle is reached, the slide bar 309 is released. Under the elastic force of the spring 307, the mounting plate 308 resets the slide bar 309 and the limiting block 310, allowing the limiting block 310 to again limit the rotation of the rotating block 305, preventing it from rotating arbitrarily. When the locomotive encounters bumps during operation, the impact force is first transmitted to the backrest body 2, which then transmits the force to the buffer pad 403. The buffer pad 403 then transmits the force to the elastic rubber block 402. The 402 elastic rubber block has good elasticity and can effectively absorb and disperse these impacts, reduce vibrations to the rider's back, and provide a comfortable support experience for the rider.
