The embodiments listed in the present invention are only used to illustrate the present invention and are not used to limit the scope of the present invention. Any obvious modifications or changes made to the present invention do not depart from the spirit and scope of the present invention.

[0029] When the car is driving on a bumpy road, each wheel 3 can be independently damped by the suspension system 4.

[0031] In addition, when a wheel 3 is being damped by the suspension system 4, the suspension systems 4 on the other three wheels 3 will also work synchronously through the cooperation of the frame 2 and the transmission structure, so that the suspension systems 4 on the four wheels 3 can be damped at the same time, with higher damping efficiency and better effect.

[0033] See also Figures 4 to 9 The suspension system 4 includes an I-shaped base 41, which is connected to the bottom plate 1 through a bracket. An upper fork arm 43 and a lower fork arm 42 are respectively provided at the upper and lower ends of both sides of the I-shaped base 41.

The upper fork arm 43 and the lower fork arm 42 located on the same side cooperate with each other and form a set of double fork arm structures;

[0034] The suspension system 4 includes two sets of double wishbone structures, which are symmetrically arranged with the I-shaped base 41 as the center. A connecting seat 44 is arranged at one end of each double wishbone structure away from the I-shaped base 41. The upper and lower ends of the connecting seat 44 are respectively rotatably connected to two brackets in the corresponding upper wishbone 43 and two brackets in the corresponding lower wishbone 42. A wheel shaft sleeve 45 is fixed to the middle part of the outer side of the connecting seat 44, and one end of the wheel axle of the wheel 3 is inserted and installed in the wheel shaft sleeve 45.

[0035] A first rotating shaft 411 is provided in the lower fork arm 42, and the first rotating shaft 411 is rotatably connected to the middle part between the two brackets in the lower fork arm 42, and both ends of the first rotating shaft 411 extend to the outside of the lower fork arm 42, and both ends of the first rotating shaft 411 are rotatably connected to connecting rods 46, one end of the two connecting rods 46 extends upward to one side of the corresponding upper fork arm 43, and the top ends of the two connecting rods 46 are rotatably connected to the upper fork arm 43, and the outer sides of the top ends of the two connecting rods 46 are connected to second rotating shafts 412, and one end of the two second rotating shafts 412 are rotatably connected to L-shaped brackets 47, and the frame of the L-shaped bracket 47 is provided with a third rotating shaft 413 at its turning position, and one end of the third rotating shaft 413 is rotatably connected to the I-shaped base 41;

[0036] The suspension system 4 is provided with four L-shaped brackets 47, and each of the four L-shaped brackets 47 is grouped into two to form a bracket structure.

[0038] In this embodiment, the double fork arm structure formed by the upper fork arm 43 and the lower fork arm 42 can keep the wheel 3 stable when it rises and falls, so that the wheel always remains vertical to the ground. When the wheel falls to the ground after rising, it can stably contact the ground without deflection, ensuring driving safety. When the wheel 3 is lifted upward, the double fork arm structure will synchronously tilt upward. At this time, the second shock absorber 410 connected to the lower fork arm 42 will be rotationally compressed and used for buffering and shock absorption. At the same time, the first shock absorber 48 connected to the upper side of the upper fork arm 43 will be synchronously horizontally compressed and used for buffering and shock absorption again. The first shock absorber 48 and the second shock absorber 410 cooperate with each other to buffer and shock absorb the double fork arm structure at the same time, so that the wheel 3 can be buffered to the greatest extent, and the ups and downs of the wheel 3 will be more stable.
