Technical Field

[0001] The utility model relates to the technical field of front shock-absorbing structures of electric tricycles, in particular to a front shock-absorbing assembly of an electric tricycle. Background Art

[0002] The front shock absorber assembly of an electric tricycle is an important component of the electric tricycle. It mainly relies on the working principle of springs and dampers to achieve the shock absorption effect. When the electric tricycle is traveling on an uneven road, the wheels will be impacted by the ground, and this impact will be transmitted to the driver and passengers through the frame. At this time, the spring in the front shock absorber assembly will absorb part of the vibration, and the damper will produce a damping effect, reducing the vibration of the spring, so that the driver and passengers can feel a smoother ride. Generally, one damper corresponds to one spring. Therefore, the existing front shock absorber assembly has a limited range of shock absorption and compression resistance, a small range of use, and the spring is installed on the outside of the damper piston rod, which is not easy to replace, and there are certain shortcomings.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] Some embodiments of the utility model are described below in conjunction with the accompanying drawings to provide a front shock absorber assembly for an electric tricycle.

[0025] Embodiment 1:

[0026] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a front shock absorber assembly for an electric tricycle, including a connecting seat 100, a mounting rod 200, a shock absorber body 300 and a shock absorbing component 400.

[0027] Specifically, the mounting rod 200 is inserted into the connecting seat 100, and a stopper 201 is arranged on the mounting rod 200. The bottom of the mounting rod 200 is threadedly connected with a first nut 202, and the stopper 201 has a blocking effect, so that the mounting rod 200 can be conveniently fixed to the connecting seat 100 through the first nut 202. After installation, the shock absorber assembly can be conveniently fixed to the electric tricycle through the mounting rod 200.

[0028] Specifically, the shock absorber body 300 includes a piston rod 302 inserted into the connecting seat 100, a shock absorber shell 301 slidably connected to the piston rod 302, and scale lines 305 arranged at the front ends of the shock absorber shell 301 and the piston rod 302. When installing the shock absorber assembly 400, the scale lines 305 can be referred to, and the position of the shock absorber assembly 400 can be accurately adjusted for symmetry. The outer sides of the shock absorber shell 301 and the piston rod 302 are both provided with limiting grooves 306. The bottom of the piston rod 302 is provided with a piston 3021, and the piston 3021 is provided with a small hole, and the small hole can convey oil. The friction between the hole wall and the oil and the internal friction between the oil molecules will form a certain damping force on the piston 3021 moving up and down to reduce shock. The top of the piston rod 302 is inserted into the connecting seat 100, and the top of the piston rod 302 is threadedly connected with a second nut 303. The top of the piston rod 302 is inserted into the connecting seat 100, and then the second nut 303 is rotated to fix it, so as to install or remove the shock absorber body 300. The interior of the shock absorber shell 301 is filled with oil, and a mounting hole 304 is opened at the bottom of the shock absorber shell 301, and the mounting hole 304 is used to install the front wheel.

[0029] Specifically, the shock absorbing assembly 400 includes an upper mounting seat 401 inserted into the piston rod 302, a spring 403 arranged at the bottom of the upper mounting seat 401, a lower mounting seat 404 arranged at the bottom of the spring 403, and a third nut 402 threadedly connected to the upper mounting seat 401 and the lower mounting seat 404. The upper mounting seat 401 and the lower mounting seat 404 have the same structure. The upper mounting seat 401 and the lower mounting seat 404 can be inserted into the piston rod 302 and the shock absorber shell 301 respectively. After insertion, the third nut 402 is rotated to fix the upper mounting seat 401 and the lower mounting seat 404. The shock absorbing assembly 400 can be installed or removed by rotating the third nut 402, thereby achieving the effect of quickly replacing the shock absorbing assembly 400 without disassembling the shock absorber body 300. Then, a certain number of shock absorbing assemblies 400 can be installed according to actual needs. The more the number of shock absorbing assemblies 400, the better the shock absorption and pressure resistance effect, and the wider the scope of use.

[0030] Embodiment 2:

[0031] Reference Figure 1 and Figure 6 , which is the second embodiment of the utility model, which is different from the first embodiment in that it also includes a dustproof cloth 500, and an elastic band 501 is arranged inside the dustproof cloth 500. The two elastic bands 501 are respectively tied to the limiting grooves 306 on the shock absorber housing 301 and the piston rod 302. The elastic bands 501 can be placed in the limiting grooves 306 on the shock absorber housing 301 and the piston rod 302 so as to fix the dustproof cloth 500 on the shock absorber housing 301 and the piston rod 302. After fixation, the dustproof cloth 500 can play a dustproof effect and prevent dust and other dirt from entering the shock absorber housing 301.

[0032] The working principle and use process of the utility model: when in use, the upper mounting seat 401 and the lower mounting seat 404 can be inserted into the piston rod 302 and the shock absorber shell 301 respectively, and the third nut 402 can be rotated to fix the upper mounting seat 401 and the lower mounting seat 404 after insertion, and the shock absorbing assembly 400 can be installed or removed by rotating the third nut 402, so as to achieve the effect of quickly replacing the shock absorbing assembly 400 without disassembling the shock absorber body 300, and then a certain number of shock absorbing assemblies 400 can be installed according to actual needs. 00, the more the shock absorbing components 400 are, the better the shock absorbing and pressure resistance effects are, and the wider the scope of use. At the same time, when installing the shock absorbing components 400, the scale line 305 can be referred to to accurately adjust the position of the shock absorbing components 400 for symmetry. Since the outer sides of the shock absorber housing 301 and the piston rod 302 are provided with limiting grooves 306, the dustproof cloth 500 can be fixed to the shock absorber housing 301 and the piston rod 302 by the elastic band 501. After fixation, it can play a dustproof effect and prevent dust and other dirt from entering the shock absorber housing 301.
