Problems solved by technology

At present, the front cabin skeleton structure used in electric vehicles has various cross-sectional forms, so the processing technology is complicated, and a large number of large-scale stamping and machining equipment are required
And some beam cross-section structures are relatively simple, such as channel steel, but their strength is very poor.
If channel steel with a large interface is used simply to increase the strength of the installation structure, it will increase the weight and cost of the large frame

Embodiment Construction

[0014] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0015] See Figure 1-3 , A new front cabin skeleton structure of an electric vehicle, which includes a front cabin left longitudinal beam 4 and a front cabin right longitudinal beam 8. A front cabin cross beam skeleton structure 3 is provided between the front cabin left longitudinal beam and the front cabin right longitudinal beam, The frame structure of the front cabin cross beam and the left longitudinal beam of the front cabin and the right longitudinal beam of the front cabin form a frame-shaped front cabin skeleton structure. The frame-shaped front cabin skeleton structure divides the front cabin of the electric vehicle into two upper and lower layers, and the lower layer It is equipped with powertrain left suspension 5, powertrain right suspension 7 and powertrain rear suspension 6. The upper layer is equipped with IPU mounting holes 1 and DCDC mounting holes...

Abstract

The invention relates to a novel front cabin skeleton structure of an electric automobile. The novel front cabin skeleton structure comprises a front cabin left longitudinal beam and a front cabin right longitudinal beam, and a front cabin cross beam skeleton structure is arranged between the front cabin left longitudinal beam and the front cabin right longitudinal beam. The front cabin cross beam skeleton structure, the front cabin left longitudinal beam and the front cabin right longitudinal beam form a frame type front cabin skeleton structure. The novel front cabin skeleton structure of the electric automobile facilitates mounting of a power assembly and electrical appliance parts, front cabin space is effectively used, the vibration and impulse loads subjected by a front cabin are isolated or reduced, and the strength and the rigidity of the front cabin skeleton structure are effectively improved.

Description

Technical field [0001] The invention relates to a new type of front cabin skeleton structure, in particular to a new type of front cabin skeleton structure used for installation of electric vehicle power assembly and electrical components. Background technique [0002] It has only been more than a hundred years since the invention of the automobile, but looking back on this history, we can see that the automobile has played an important role in promoting economic development and social progress. With the increase in car ownership and the increasing popularity, people's lives have been greatly improved, people's activity radius has been expanded, and the needs of modern industry have been adapted. At the same time, the disadvantages caused by industrialization and urbanization have also been alleviated. However, while people enjoy automobile civilization, they must also face the negative effects of automobiles: environmental pollution and energy crisis. In this case, electric veh...
