Abstract

The utility model provides a steel pipe structure of a protective frame of an electric vehicle, which comprises a pipe body, wherein a friction sleeve, foam and a spring are sequentially arranged inside the pipe body from outside to inside, and a reinforced structure is arranged at the joint of the pipe body and a rubber ring; according to the utility model, the reinforcing structure and the foam are added, so that the load bearing capacity of the pipe body is increased, and the pipe body is not easy to bend and shrink; the increase of the spring can avoid flying out after fracture and hurting human body.

Description

Steel pipe structure of electric vehicle protection frame

Technical Field

The utility model mainly relates to the field of electric vehicle protection, in particular to a steel pipe structure of an electric vehicle protection frame.

Background

The electric vehicle protection frame is used for protecting the electric vehicle.

However, in the prior art, the steel pipe of the protective frame is only a common hollow pipe, and the protective capacity is limited. When an accident occurs, the broken part is easy to prick the human body, and the buffer function is insufficient.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a steel pipe structure of a protective frame of an electric vehicle, which comprises a pipe body 1, wherein a friction sleeve 2, foam 3 and a spring 4 are sequentially arranged inside the pipe body 1 from outside to inside, and a reinforcing structure 11 is arranged at the joint of the pipe body 1 and the friction sleeve 2.

Preferably, the tube body 1 is made of 304 stainless steel.

Preferably, the friction sleeve 2 is made of rubber.

Preferably, the foam 3 is PU foam.

Preferably, the spring 4 is a coil spring.

Preferably, reinforced structure 11 slope laminating is at pipe shaft 1 inner wall, and reinforced structure 11 material is stainless steel material, fixes with pipe shaft 1 through the welding.

Preferably, the reinforcing structure 11 is provided in plurality, and the plurality of reinforcing structures 11 are disposed at equal angles around the axis of the pipe body 1.

The utility model has the beneficial effects that: by adding the reinforcing structure and the foam, the load bearing capacity of the pipe body is increased, and the pipe body is not easy to bend and shrink; the increase of the spring can avoid flying out after fracture and hurting human body.

FIG. 2 is a cross-sectional view of the present invention;

in the figure, the position of the upper end of the main shaft,

1. a tube body; 2. a friction sleeve; 3. soaking cotton; 4. a spring; 11. and (5) reinforcing the structure.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.

As shown in fig. 1-2, the present invention includes: pipe shaft 1, pipe shaft 1 inside from outer to interior friction cover 2, bubble cotton 3 and spring 4 are equipped with in proper order, and the pipe shaft 1 is equipped with reinforced structure 11 with the junction of friction cover 2.

In this embodiment, the tube body 1 is preferably made of 304 stainless steel.

By adopting the structure, the service life of the pipe body 1 is prolonged, and meanwhile, the pipe body is not easy to be damaged by external force.

In the present embodiment, the friction sleeve 2 is preferably made of rubber.

Set up above-mentioned structure, rubber material own possess good frictional force be convenient for connecting pipe shaft 1 and bubble cotton 3, and rubber easily forms various shapes after the vulcanization mould pressing simultaneously, is convenient for dodge reinforced structure 11.

In the present embodiment, the foam 3 is preferably PU foam.

By adopting the structure, the foam 3 plays a role in buffering.

In the present embodiment, the spring 4 is preferably a coil spring.

With the structure, the spring 4 is used for avoiding flying out after fracture and hurting human body.

In this embodiment, it is preferable that the reinforcing structure 11 is attached to the inner wall of the pipe body 1 in an inclined manner, and the reinforcing structure 11 is made of a stainless steel material and fixed to the pipe body 1 by welding.

In the present embodiment, it is preferable that the reinforcing structure 11 is provided in plurality, and the plurality of reinforcing structures 11 are disposed at equal angles around the axis of the pipe body 1.

By adopting the structure, the strength of the pipe body 1 is improved, and the pipe body is not easy to be damaged by external force.

In use, the reinforcing structure 11 and the foam 3 increase the load bearing capacity of the pipe body 1 and are not easy to bend and collapse; the spring 4 is added to avoid flying out after fracture and hurting human body, and the friction sleeve 2 is convenient for connecting the pipe body 1 and the foam 3.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
