[0027] Reference Figures 1-5A shock-absorbing structure for the rear axle of a tricycle includes a rear axle body 1. Two bow plates 2 are fixedly mounted on the surface of the rear axle body 1. A connecting plate 3 is fixedly mounted on the top of the two bow plates 2. A mounting plate 4 is provided on the top of the connecting plate 3. A connecting block 6 is rotatably connected to the bottom of the mounting plate 4 near the middle position. First rotating blocks 7 are rotatably connected to the bottom of the mounting plate 4 near both ends. Second rotating blocks 8 are rotatably connected to the top of the connecting plate 3 near both ends. A first shock-absorbing mechanism 9 is provided between the first rotating blocks 7 and the second rotating blocks 8. A second shock-absorbing mechanism 10 is provided at the bottom of the connecting block 6. The end of the second shock-absorbing mechanism 10 away from the connecting block 6 is connected to the connecting plate 3. The bow plates 2 are installed on the rear axle body 1, the connecting plate 3 is installed on the two bow plates 2, and then the mounting plate 4 is placed on the connecting plate 3, so that the tricycle box is installed on the mounting plate 3. The mounting plate 4 is equipped with a connecting block 6 and a second damping mechanism 10 between the mounting plate 4 and the connecting plate 3, which can achieve a vertical damping effect. The connecting block 6 can rotate left and right with the mounting plate 4. Two sets of first damping mechanisms 9 are set near both ends between the mounting plate 4 and the connecting plate 3. When one side of the wheel is bumpy, the rotation of the mounting plate 4 and the connecting block 6 can act on the corresponding first damping mechanism 9 on one side of the carriage to improve the damping effect. Therefore, the two bow plates 2 and the second damping mechanism 10 can provide vertical damping for the entire carriage. When one side of the wheel is bumpy, the first damping mechanism 9 on the corresponding side can be used for damping. The triple damping mechanism can achieve a better damping effect. The first rotating block 7 and the second rotating block 8 can make the first damping mechanism 9 better adapt to the swaying of the carriage.

[0028] Furthermore, the first damping mechanism 9 includes two first fixed blocks 94, and a first spring 92 is fixedly installed between the two first fixed blocks 94. A first shock absorber 93 is provided inside the first spring 92. The two ends of the first shock absorber 93 are fixedly connected to the two first fixed blocks 94 respectively. The first spring 92 and the first shock absorber 93 in the first damping mechanism 9 work together to achieve the damping effect.

[0029] Furthermore, both first fixing blocks 94 are configured as "T" shaped structures, and the surfaces of the first rotating block 7 and the second rotating block 8 are provided with "T" shaped grooves. The surfaces of both first fixing blocks 94 are provided with first bolts 91. The first vibration damping mechanism 9 can be inserted into the first rotating block 7 and the second rotating block 8 using the first fixing blocks 94, and then fastened using the first bolts 91, which facilitates installation and disassembly.

[0030] Furthermore, the second damping mechanism 10 includes two second fixed blocks 101. A second spring 104 and a telescopic rod 102 are fixedly installed between the two second fixed blocks 101. A second shock absorber 105 is provided inside the second spring 104. The two ends of the second shock absorber 105 are fixedly connected to the two second fixed blocks 101 respectively. The second spring 104 and the second shock absorber 105 in the second damping mechanism 10 work together to achieve a damping effect. The telescopic rod 102 can make the top second fixed block 101 vibrate only in the vertical direction, so that the second shock absorber 105 will not be damaged by force when the carriage shakes.

[0031] Furthermore, both the surface of the connecting block 6 and the surface of the connecting plate 3 are provided with "T" shaped grooves. Both second fixing blocks 101 are set with "T" shaped structures and both surfaces of the second fixing blocks 101 are provided with second bolts 103. The second shock absorption mechanism 10 is inserted into the "T" shaped grooves of the connecting block 6 and the connecting plate 3 through the two fixing blocks, and then fixed by the second bolts 103, which facilitates disassembly and replacement.

[0032] Furthermore, the surface of the mounting plate 4 is provided with screws 5 for connecting to the tricycle carriage.

[0033] In summary, the bow plate 2 is installed on the rear axle body 1, the connecting plate 3 is installed on the two bow plates 2, and then the mounting plate 4 is placed on the connecting plate 3, so that the tricycle box is installed on the mounting plate 4. A connecting block 6 and a second damping mechanism 10 are provided between the mounting plate 4 and the connecting plate 3, which can achieve a vertical damping effect. The connecting block 6 can rotate left and right with the mounting plate 4. Two sets of first damping mechanisms 9 are located near both ends between the mounting plate 4 and the connecting plate 3. When one wheel bumps, the rotation of the mounting plate 4 and the connecting block 6 on one side of the tricycle box acts on the corresponding first damping mechanism 9, improving the damping effect. Therefore, the two bow plates 2 and the second damping mechanism 10 can provide vertical damping for the entire tricycle box. When one wheel bumps, the corresponding first damping mechanism 9 on that side can provide damping. This triple damping mechanism can better achieve the desired effect. The first rotating block 7 and the second rotating block 8 allow the first shock-absorbing mechanism 9 to better adapt to the swaying of the carriage. The first spring 92 and the first shock absorber 93 in the first shock-absorbing mechanism 9 work together to achieve a shock-absorbing effect. The first shock-absorbing mechanism 9 can be inserted into the first rotating block 7 and the second rotating block 8 using the first fixing block 94, and then fastened with the first bolt 91, which facilitates installation and disassembly. The second spring 104 and the second shock absorber 105 in the second shock-absorbing mechanism 10 work together to achieve a shock-absorbing effect. The telescopic rod 102 ensures that the second fixing block 101 at the top can only vibrate in the vertical direction, so that the second shock absorber 105 will not be damaged by force when the carriage sways. The second shock-absorbing mechanism 10 is inserted into the "T"-shaped groove of the connecting block 6 and the connecting plate 3 through two fixing blocks, and then fixed with the second bolt 103, which facilitates disassembly and replacement.
