specific Embodiment 1

[0033] figure 1 , figure 2 , image 3 , Figure 4 and Figure 5a , Figure 5b , Figure 5c Constitute a specific embodiment of the present invention.

[0034] see figure 1 , the present embodiment includes three independent structural units, the first structural unit constitutes the chassis frame 1, the second structural unit constitutes the cage box 2, and the third structural unit constitutes the cover 3; the chassis frame 1 and the The cage-shaped box body 2 is fixedly connected to form a combined load-bearing frame, and a fixed cover 3 is installed on the basis of the combined load-bearing frame, and the cover 3 is fixedly installed on the front end, rear end or front end of the combined load-bearing frame And the rear end, 3 pairs of covering parts constitute the wrapping structure of the combined vehicle frame, and form the external modeling structure of the main body structure of the automobile.

[0035] refer to figure 2 , the chassis frame 1 of the present ...

specific Embodiment 2

[0045] refer to Figure 4 The main difference between this embodiment and the previous embodiment is that part or all of the covering parts are composed of some surface structural parts, the structural parts are fixedly installed on the combined vehicle frame, and there is also a connection relationship between the covering parts.

specific Embodiment

[0047] The characteristics of other specific embodiments of the present invention are:

[0048] Part of the cover 3 can be adopted to be composed of an integral volume block, or a combination that is divided into a plurality of volume blocks 3-4 and connected to each other (divided according to the volume characteristics of the cover part); the volume block is a surface band The shell, the solid body filled with foaming light material inside, the cover part 3 is fixed on the chassis frame 1 and / or the cage box body 2 .

[0049] Also can be that part cover 3 is made of integral curved surface block, or is formed by being divided into a plurality of curved surface blocks 3-5 and the combination that is connected with each other (divided according to the characteristics of curved surface block); Described curved surface block is a band thickness and The structural part of the rib, the cover part 3 is fixed on the chassis frame 1 and / or the cage box body 2 .

Abstract

The invention relates to a triad structure light electric vehicle main body structure. The structure is characterized by comprising three independent structure units, a first structure unit forms an electric vehicle underframe (1), a second structure unit forms an electric vehicle cage type box body (2), and a third structure unit forms an electric vehicle cover panel (3); wherein the underframe (1) and the cage type box body are fixedly connected to form a combined type load bearing frame, the cover panel (3) is fixedly connected on the combined type load bearing frame, and the cover panel (3) forms a package structure inward and forms a main body structure of vehicle external styling outward. The invention has the beneficial effects of lighting realization, high safety and low cost smallscale production or piece production, as triad structure car model production does not require opening a steel mould, stamping production line and welding production line are not required to be established, each structure element can be produced by low cost technology and equipment, small scale production and even piece production is easy to be realized.

Description

technical field [0001] The invention relates to a main body structure of an electric vehicle body, in particular to a light-weight main structure of an electric vehicle with a ternary structure. It belongs to the field of new energy vehicles. Background technique [0002] In recent years, electric vehicles have been highly valued at home and abroad, and the development voice is very high. The country has also issued a series of encouraging policies. However, there are very few electric vehicle products (especially pure electric vehicles) to choose from on the market, and the electric vehicle market is long-awaited, but it is still late. The reason is that power battery technology has not yet been fully developed. In addition to meeting the requirements for the use of electric vehicles, the lack of innovation in the structure and manufacturing mode of electric vehicles is an important reason. [0003] At present, the industrialization of pure electric vehicles is divided in...
