[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Refer to the attached Figure 1-5 , an electric vehicle triangular saddle support frame, comprising a seat frame 1, a shock absorbing unit connected to the saddle is symmetrically arranged at the rear of the seat frame 1;

[0026] The shock absorbing unit comprises a lower cylinder 2 and an upper cylinder 3, wherein the lower cylinder 2 is fixedly connected to the vehicle seat frame 1, and the upper cylinder 3 is sleeved outside the lower cylinder 2 and connected via a shock absorbing spring 4, the top of which extends out of the lower cylinder 2, so that there is a gap between the top of the inner cavity of the upper cylinder 3 and the top of the lower cylinder 2, so that the electric vehicle saddle can be squeezed downward for shock absorption;

[0027] A damping plate 22 is circumferentially provided on the outer wall of the lower cylinder 2, and a damping ring 31 cooperating with the damping plate 22 is provided in the upper cylinder 3. When the electric vehicle saddle is squeezed downward for shock absorption, the upper cylinder 3 drives the damping ring 31 to squeeze the damping plate 22 downward so that the damping plate 22 is deformed, thereby improving the downward shock absorption effect. After completing the downward squeezing movement, the damping ring 31 moves to the bottom of the damping plate 22. When the electric vehicle saddle is reset upward, the damping ring 31 will push the damping plate 22 again so that the damping plate 22 is deformed. At this time, the damping plate 22 provides a damping force to prevent the electric vehicle saddle from rebounding quickly, thereby further improving the shock absorption effect.

[0028] In this embodiment, the top of the damping sheet 22 is tilted downward to form a slope 221, and the top of the slope 221 forms an obtuse angle with the side wall of the lower cylinder 2. The bottom of the slope 221 away from the lower cylinder 2 is provided with a slope 222 inclined toward the lower cylinder 2, and an arc groove 223 is provided in the slope 222. When the damping sheet 22 is deformed downward, the spring piece 224 will be located in the arc groove 223, and will not be deformed, and will not further increase the damping force exerted on the saddle downward. The damping sheet 22 is provided with a spring piece 224, and the end of the spring piece 224 away from the lower cylinder 2 is arranged in the arc groove 2 At the notch of 23, the downward movement of the damping ring 31 will squeeze the slope 221, causing the damping plate 22 to deform downward to provide shock absorbing force. When the damping ring 31 is reset downward, the damping ring 31 will squeeze the inclined surface 222, further causing the inclined surface 222 to deform upward. At this time, one side of the inclined surface 222 will push the spring 224 to move, and the spring 224 will be deformed under pressure. At this time, the sum of the elastic deformation force of the spring 224 and the upward deformation force of the inclined surface 222 will greatly reduce the upward reset force of the shock absorbing spring 4, greatly reduce the resilience of the electric vehicle saddle, and improve the shock absorbing effect.

[0029] In this embodiment, there is a gap between the outer wall of the lower tube 2 and the inner wall of the upper tube 3. When the upper tube 3 moves up and down to reduce pressure, it can move slightly left and right, which helps to improve the shock absorption effect, and the slight left and right movement will not cause the shock absorption spring 4 to deform too much and be damaged.

[0030] In this embodiment, a pressure relief plate 21 is provided circumferentially on the outer wall of the lower tube 2. The pressure relief plate 21 is made of rubber. When the upper tube 3 moves slightly left or right, its inner wall will press against the outer wall of the pressure relief plate 21 to reduce pressure, thereby avoiding excessive impact force between the upper tube 3 and the lower tube 2.

[0031] In this embodiment, a connecting column 32 for connecting to the saddle is provided at the top of the upper tube 3, and a threaded hole 33 is provided on the connecting column 32 to facilitate the installation between the support frame and the saddle.
