Embodiment 1

[0030] Such as Figure 1-4 As shown, this embodiment provides an adjustable shock absorber suitable for new energy vehicles, including a housing 1, a push rod 8 with one end disposed in the inner cavity of the housing 1, and a bushing 5 sleeved outside the housing 1; The part of the push rod 8 located in the inner cavity of the housing 1 is provided with a first piston 801, a stopper 803 and a second piston 802 in sequence, and the first piston 801 and the second piston 802 respectively form a first piston 801 with the two end surfaces of the housing 1. The damping chamber 10 and the second damping chamber 11 are communicated between the first damping chamber 10 and the second damping chamber 11 through a damping pipe 13, and a regulating valve 12 is provided on the damping pipe 13; the bushing 5 is movably installed on the outside of the housing 1 and There are several sets of adjusting threaded holes 501 distributed along the axial direction of the ejector rod 8, and the lim...

Embodiment 2

[0036] Such as figure 1 and 2 As shown, this embodiment provides an adjustable shock absorber suitable for new energy vehicles, including the structure in Embodiment 1. In addition, the outer surface of one end of the housing 1 is provided with a first threaded area 101, the first threaded area 101 is installed with the first adjusting nut 2, and the first spring 3 is arranged between the first adjusting nut 2 and the bushing 5, the first The spring 3 is installed coaxially with the housing 1; the outer surface of the other end of the housing 1 is provided with a second threaded area 102, and the second threaded area 102 is equipped with a second adjusting nut 14, and the gap between the second adjusting nut 14 and the bushing 5 is A second spring 7 is provided, and the second spring 7 is installed coaxially with the casing 1 . Both the first adjusting nut 2 and the second adjusting nut 14 are provided with a plurality of opening grooves 16 outside. When the vehicle vibrate...

Embodiment 3

[0038] This embodiment provides a new energy vehicle, including the adjustable shock absorber suitable for a new energy vehicle described in Embodiment 1 or 2.

[0039] The working principle of the present invention is: by adjusting the regulating valve 12 on the damping pipeline 13, the flow cross-sectional area of ​​the damping pipeline 13 can be changed, thereby changing the damping of the shock absorber; The position can change the compression degree of the first spring 3 and the second spring 7, thereby changing the damping of the shock absorber; by corresponding the different sets of adjusting threaded holes 501 distributed axially along the push rod 8 to the limit slot 805, And fixed with the adjusting screw 6, the length adjustment of the ejector rod 8 protruding from the housing 1 can be realized, thereby achieving the purpose of adjusting the height of the shock absorber; the invention is easy to operate, simple in structure, and low in manufacturing cost.

Abstract

The invention discloses a new energy automobile and an adjustable shock absorber suitable for the new energy automobile. The adjustable shock absorber comprises a shell, an ejector rod and a lining, wherein one end of the ejector rod is arranged in an inner cavity of the shell, and the shell is sleeved with the lining. A first piston, a limiting block and a second piston are sequentially arranged on the portion, located in the inner cavity of the shell, of the ejector rod, a first damping cavity and a second damping cavity are formed between the first piston and one end face of the shell and between the second piston and the other end face of the shell correspondingly, the first damping cavity communicates with the second damping cavity through a damping pipeline, and an adjusting valve is arranged on the damping pipeline. The lining is movably installed outside the shell and provided with a plurality of sets of adjusting threaded holes distributed in the axial direction of the ejector rod, the limiting block is provided with a set of limiting grooves, and the lining and the ejector rod are relatively fixed in the mode that an adjusting screw penetrates through one set of adjusting threaded holes and the limiting grooves. The shell is provided with a long-strip-shaped hole for containing the adjusting screw to move in the axial direction of the ejector rod. Damping and height adjustment can be achieved, the operation is convenient, and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a new energy vehicle and an adjustable shock absorber suitable for the new energy vehicle. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source, or the use of conventional vehicle fuels, the adoption of new vehicle power devices, and the comprehensive vehicle power control and advanced technology in driving, forming advanced technical principles and new features. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles and hydrogen engine vehicles. [0003] In order to reduce the vibration of the new energy vehicle during driving, it is necessary to install a shock absorber. The damping and height of the existing shock absorbers suitable for new energy vehicles cannot be adjusted, so that the vehicle cannot meet the o...
