Abstract

The invention discloses a front suspension system of an electric wheelchair, which is mainly arranged between the vehicle frame of the electric wheelchair and each front wheel, and one end of the front wheel frame of the front suspension system is pivotably combined with the vehicle frame The other end of the front pivot is combined with the front wheel. By setting the front shock absorber on the first body section of the horizontal front wheel frame, the upward pivoting angle range of the front wheel frame can be increased, and the front wheel can pass through. The bearing range of the raised bearing surface; through the elastic resistance member on the front pivot, one end of the elastic resistance member is driven and combined with the front wheel frame, and the other end is against the seat on the frame, and the front wheel passes through the bump bearing surface At the same time, it can drive the front wheel frame to pivot, and the front wheel frame drives the torsion elastic resistance part. The elastic resistance part is twisted and naturally generates a reaction force to the front wheel frame, thereby ensuring that the front wheel has reverse resistance when passing the bumpy road. Force, to avoid overturning of the overall frame overturning or forward tilting, improve driving stability and safety.

Description

technical field [0001] The invention relates to a suspension structure of an electric wheelchair, which is related to a suspension device of a vehicle. Background technique [0002] Suspension system, generally refers to a vehicle system composed of shock absorbers and connecting rods, and is mainly used to connect between the vehicle and the wheels, through the configuration of the suspension system system to reduce the impact of bumpy roads on driving Bounce or vibrate, but can maintain the comfort of passengers sitting in the car body. [0003] like figure 1 Shown is an electric wheelchair C1, said electric wheelchair C1 is translated on a load-bearing surface G, said electric wheelchair C1 has two front cantilevers C12 arranged at the front end of a frame C11, and two said front cantilever C12 are respectively combined and arranged A front shock absorber C13, the rear end of the vehicle frame C11 is provided with two rear cantilever arms C14, and the two rear cantileve...
