Return spring assembly for electric vehicle

Abstract

The utility model provides a return spring assembly for an electric vehicle, and relates to the technical field of electric vehicles. The reset spring assembly for the electric vehicle comprises a reset spring body, a buffer gasket is arranged at the bottom of the reset spring body, lantern rings are installed on the top of the buffer gasket, a plurality of clamping jaws are installed on the sides, close to each other, of the lantern rings, and the same piston rod is movably arranged on the inner side of the buffer gasket. The piston rod is located on the inner side of the reset spring body, the multiple clamping jaws are annularly and evenly distributed on the lantern ring, the clamping jaws are located on the lantern ring and arranged inwards in an inclined mode, and the clamping jaws are attached to the piston rod. The reset spring assembly for the electric vehicle has the advantages that the multiple clamping jaws are buckled on the piston rod, so that close-fitting operation is formed between the buffer gasket and the piston rod, and meanwhile the piston rod can be conveniently assembled and disassembled through the clamping jaws arranged in the oblique angle mode.

Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a restoring spring assembly for electric vehicles. Background Art

[0002] Electric vehicles, that is, electric-driven vehicles, are also called electric-driven vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as energy sources, and use controllers, motors and other components to convert electrical energy into mechanical energy to control the current size to change the speed of the vehicle. In order to increase the comfort of electric vehicles, electric vehicles are equipped with restoring springs and their accessories to form a shock-absorbing effect. In the existing electric vehicle restoring spring assembly, the buffer washer and the piston rod are loosely matched, which will cause movement when the shock absorber moves at high frequency, thereby generating movement noise. Utility Model Content

[0003] Based on the technical problems existing in the background technology, the utility model proposes a restoring spring assembly for electric vehicles.

[0004] The utility model provides a restoring spring assembly for an electric vehicle, comprising a restoring spring body, a buffer washer is arranged at the bottom of the restoring spring body, a collar is installed at the top of the buffer washer, and a plurality of claws are installed on the sides of the collars close to each other.

[0005] Preferably, a piston rod is movably disposed inside the buffer washer, and the piston rod is located inside the restoring spring body.

[0006] Preferably, the plurality of claws are evenly distributed on the collar in a ring shape.

[0007] Preferably, the claw is located on the collar and is arranged obliquely inwards, and the claw is in contact with the piston rod.

[0008] The restoring spring assembly for electric vehicles proposed by the utility model has the following beneficial effects: a plurality of claws are buckled on the piston rod, so that a tight fit is formed between the buffer washer and the piston rod, and the claws arranged at an oblique angle can facilitate the installation and disassembly of the piston rod.

[0012] Reference Figure 1-Figure 2 The utility model provides a restoring spring assembly for an electric vehicle, a restoring spring body (1), a buffer washer 2 is provided at the bottom of the restoring spring body 1, a collar 3 is installed on the top of the buffer washer 2, and a plurality of claws 4 are installed on the sides of the collar 3 close to each other.

[0013] In a specific embodiment, a piston rod 5 is movably disposed inside the buffer washer 2 , and the piston rod 5 is located inside the restoring spring body 1 .

[0014] In a specific embodiment, a plurality of claws 4 are evenly distributed on the collar 3 in a ring shape. The plurality of claws 4 are evenly distributed on the collar 3 and can evenly push and clamp the piston rod 5 so that the piston rod 5 is in a tight fit.

[0015] In a specific embodiment, the claw 4 is located on the collar 3 and is tilted inwardly, and the claw 4 fits the piston rod 5 . The tilted setting of the claw 4 can clamp the piston rod 5 .

[0016] The working principle of the utility model is as follows: the skewed setting of the claw 4 can clamp the piston rod 5, and the multiple claws 4 are evenly distributed on the ring 3, which can evenly push the piston rod 5 to form a tight fit state.

[0017] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
