detailed description

Next, with reference to the accompanying drawings, through the description of the embodiments, the specific implementation of the utility model will be further described in detail, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the utility model .

The structure of the present invention as shown in Figures 1 to 5 is a front longitudinal beam assembly of an electric vehicle with a threaded casing structure, and the front cabin is provided with a front longitudinal beam 2 made of aluminum profiles. The front longitudinal beam 2 is two pieces, its rear end is fixed on the floor front beam 6; its front end is fastened to the front longitudinal beam front end plate 3.

In order to overcome the defects of the prior art and realize the purpose of the invention of the stable installation and fixing of the front cabin bracket, the technical solution adopted by the utility model is:

As shown in Figures 1 to 5, a front longitudinal beam assembly of an electric vehicle with a threaded casing structure according to the present invention, the front longitudinal beam 2 is arranged in the front cabin, and its material is an aluminum profile; A front compartment support 1 is arranged in the front compartment of the front compartment, and the front compartment support 1 is installed on the front longitudinal beam 2 through the front compartment support installation structure 4 .

By adopting the above technical scheme, the installation and fixing of the DC/DC and the storage battery in the front cabin are more stable and reliable, the connection structure is compact, and the installation and fixing are convenient.

See Figure 2 and Figure 3:

The front cabin bracket installation structure 4 is arranged in the front longitudinal beam 2; the front cabin bracket installation structure 4 is provided with a threaded sleeve 7, and the open end of the threaded sleeve 7 is provided with an internal thread; The front cabin bracket 1 is fastened on the front longitudinal beam 2 through the installation bolt 10; the installation bolt 10 passes through the installation hole on the front cabin bracket 1, and then passes through the front The installation hole on the longitudinal beam 2 forms a screw tight fit with the internal thread of the threaded sleeve 7 .

The threaded fastening connection between the threaded sleeve 7 and the mounting bolt 10 can greatly improve the connection strength, and the processing and manufacturing of the connection structure is also relatively convenient.

See Figure 3 and Figure 5:

The front cabin bracket installation structure 4 is provided with a front cabin bracket installation structure skeleton 5 , and the threaded sleeve 7 is fixed by the front cabin bracket installation structure skeleton 5 .

The threaded bushing 7 is fixed by the front cabin bracket installation structure skeleton 5, so that the threaded bushing 7 is more stable and reliable when connected and fastened.

The frame 5 of the front cabin bracket installation structure is an aluminum profile, the threaded sleeve 7 is made of aluminum, and the threaded sleeve 7 is pressure riveted on the front cabin bracket installation structure 4 .
