When the wheel is impacted, the handle tube axially stretches in the aluminum cylinder, and only vibration in the axial direction can be absorbed, so that the shock absorption effect is poor.

In this regard, referring to FIG. 1, one embodiment of the present application provides a shock absorbing system 10 for a two-wheeled vehicle, the shock absorbing system 10 including a multi-swing arm mechanism 200 and a shock absorber 100 that lie in the same plane; the multi-swing arm mechanism 200 has a first end and a second end, the first end and the second end of the multi-swing arm mechanism 200 and the shock absorber 100 are all hinged with the front fork 20 of the two-wheel vehicle, and two swing arms in the multi-swing arm mechanism 200 are respectively hinged with the shock absorber 100 and the rotating shafts on the wheels 30 of the two-wheel vehicle.

The shock absorbing system 10 described above is suitable for use on the front suspension of a two-wheeled vehicle, which may include, but is not limited to, an electric vehicle, a bicycle.

In the shock absorbing system 10, when the wheel 30 of the two-wheeled vehicle is impacted, the swing arms hinged with the wheel 30 in the multi-swing arm mechanism 200 synchronously bounce, and the swing arms drive other swing arms to rotate so as to drive the shock absorber 100 to rotate, namely, the axis angle of the shock absorber 100 is variable, so that the shock absorber 100 can absorb and filter multidirectional vibration, not only the vibration of the front fork tube 20 of the vehicle in the axial direction, but also the riding comfort of the vehicle can be greatly provided; in addition, by arranging the shock absorber 100 and the multi-swing arm mechanism 200 in the same plane, each swing arm in the multi-swing arm mechanism 200 does not interfere with each other when rotating, and the shock absorber 100 can smoothly rotate under the drive of the multi-swing arm mechanism 200, so that the shock absorber 100 can be ensured to effectively absorb and filter multidirectional vibration.

The axis angle of the shock absorber 100 refers to an angle between the axis of the shock absorber 100 and the axis of the front fork 20.

In some embodiments of the present application, the number of swing arms of the multi-swing arm mechanism 200 is greater than or equal to 3, for example, 3, 4, 5 or more, if this can enable the shock absorber 100 to absorb the shock in three directions X, Y, Z, the riding comfort of the vehicle can be effectively improved.

Referring to fig. 1, the first swing arm 210 may be located above the third swing arm 230. Thus, the shock absorber 100 can be arranged outside the area surrounded by the multi-swing arm mechanism 200 and the front fork cylinder 20, so that the size of the multi-swing arm mechanism 200 can be reduced, and the weight and the occupied space of the multi-swing arm mechanism 200 can be reduced.

Referring to fig. 1, the first swing arm 210 may be bent in a direction away from the third swing arm 230, i.e., the first swing arm 210 is bent upward. So configured, when the wheel 30 of the vehicle bumps upward against an obstacle, the first swing arm 210 can effectively bounce upward, thereby enabling the shock absorber 100 to effectively absorb vibrations in that direction.

Referring to fig. 1, the third swing arm 230 may be bent in a direction away from the first swing arm 210, i.e., the third swing arm 230 is bent downward. So configured, when the wheel 30 of the vehicle bumps down through the groove, the third swing arm 230 can effectively bounce down, thereby enabling the shock absorber 100 to effectively absorb vibrations in that direction.

Referring to fig. 1, the second swing arm 220 is bent toward the front fork 20. Thus, the first swing arm 210 and the third swing arm 230 can move circumferentially.
