AI Technical Summary
The addition of drive half-shafts and steering gears to the rear suspension of high-end electric vehicles restricts the space available for shock absorbers, resulting in reduced utilization of interior space.
Design a space-enhancing shock absorber-recessed rear suspension structure for new energy vehicles. By placing the shock absorber inside the steering knuckle and setting the hinge point between the upper control arm and the upper pull arm as the third hinge point lower than the lower control arm and the steering knuckle, a through hole is formed to achieve the recessed arrangement of the shock absorber.
This effectively lowers the height of the shock absorber's upper point, freeing up space inside the car, reducing the load on the lower control arm, maintaining overall vehicle comfort, and preventing a decrease in handling stability.

[0019] Referring to Figures 1 to 4 A new energy vehicle shock absorber sinking rear suspension structure for increasing space, comprising a vehicle frame 7, a multi-link suspension structure arranged on both sides of the vehicle frame respectively;
[0020] The multi-link suspension structure comprises a steering knuckle 1, a lower control arm 2 connected at one end to the front bottom of the vehicle frame and at the other end to the bottom of one side of the steering knuckle 1, a steering gear 9 connected at one end to the middle of the vehicle frame 7 and at the other end to the upper part of one end of the steering knuckle 1, an upper control arm 5 connected at one end to the top of the front side of the vehicle frame and at the other end to the middle of the steering knuckle, a lower pull arm 3 connected at one end to the rear bottom of the vehicle frame and at the other end to the bottom of the other side of the steering knuckle, an upper pull arm 6 connected at one end to the rear top of the vehicle frame and at the other end to the top of the other side of the steering knuckle, a shock absorber 4, and an air spring 8 arranged beside the shock absorber;
[0021] The lower control arm and the steering gear are arranged on the same side, and the lower control arm is arranged below the steering gear;
[0022] The lower pull arm 3 and the upper pull arm 6 are arranged on the same side, and the lower pull arm 3 is arranged below the upper pull arm 6; the upper control arm 5 is arranged between the upper pull arm 6 and the steering gear;
[0023] An installation space is formed between the lower pull arm 3, the upper pull arm 6, the steering gear, and the lower control arm 2;
[0024] The shock absorber 4 is located inside the steering knuckle, and between the upper control arm 5 and the upper pull arm 6, both ends of the shock absorber 5 are respectively hinged to the vehicle frame 7 and the steering knuckle 1, and the hinge points are respectively a first hinge point A1 and a second hinge point A2;
