[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the shock absorber for new energy vehicles includes a piston rod 8, and the two ends of the piston rod 8 are symmetrically and movably connected with a cylinder 2. The double cylinder 2 is set to provide a good shock absorbing and buffering effect, and the other end of the cylinder 2 is connected to a hinge seat 1;

[0022] The end of the oil cylinder 2 close to the piston rod 8 is provided with an end plate 7, and the two end plates 7 are connected by a spring 9, and the spring 9 is sleeved on the piston rod 8, and the spring 9 cooperates with the oil cylinder 2 to achieve a shock-absorbing effect;

[0023] A telescopic protective sleeve 5 is also connected between the two end plates 7. The telescopic protective sleeve 5 is sleeved on the outside of the spring 9 to provide protection for the spring 9.

[0024] An adjusting nut 3 is threadedly connected to one end of the outer side of the oil cylinder 2 near the piston rod 8, and the adjusting nut 3 is in contact with the end plate 7. The position of the end plate 7 can be adjusted by adjusting the nut 3, thereby determining the compression degree of the spring 9 and adjusting the damping degree of the shock absorber.

[0025] like Figure 3 As shown, in order to improve the shock-absorbing and buffering effect in the oil cylinder 2, the oil cylinder 2 is further filled with hydraulic oil and is provided with a sliding piston 12 connected to the piston rod 8. The sliding piston 12 is provided with an oil guide hole 13 around the piston rod 8, and the oil cylinder 2 is provided with an oil inlet hole for filling the hydraulic oil. The oil guide hole 13 is used to connect the oil chambers at both ends of the sliding piston 12 to limit the circulation speed of the hydraulic oil, thereby achieving a buffering effect.

[0026] like Figure 1 As shown, in order to provide heat dissipation for the shock absorber, further, the telescopic protective cover 5 is provided with evenly distributed air guide holes 6, and the two ends of the telescopic protective cover 5 are fixed to the circumferential surface of the end plate 7 by bolts 4. When the spring 9 is in the process of extension and contraction, the telescopic protective cover 5 will also extend and contract, thereby forming a suction effect through the air guide holes 6, promoting the discharge of the airflow in the telescopic protective cover 5, and achieving the heat dissipation effect.

[0027] like Figure 3 As shown, in order to prevent the spring 9 from driving the end plate 7 to move during operation, further, the end surface of the cylinder 2 is provided with a plurality of guide holes 11 around the piston rod 8, and the end plate 7 is provided with a guide rod 10 that slides with the guide hole 11. Through the cooperation between the guide rod 10 and the guide hole 11, the end plate 7 is restricted so that it can only move along the length direction of the piston rod 8.

[0028] The working process of the utility model is as follows: the shock absorber is fixedly installed through the hinge seat 1, and then the adjusting nut 3 is rotated according to the actual use requirements, and the position of the end plate 7 is adjusted by adjusting the nut 3, so as to adjust the compression degree of the spring 9, thereby realizing the adjustment effect of the shock absorber's damping degree, which greatly reduces the maintenance and debugging costs of the car.
