Embodiment Construction

[0014] The invention discloses a pure electric vehicle frame which is flexible in application and can match various types of suspensions.

[0015] Such as figure 1 As shown, a pure electric vehicle frame disclosed by the present invention, a pure electric vehicle frame, includes a front frame 1, a middle frame 2 fixedly connected to the front frame 1, and The frame 2 is fixedly connected to the rear frame 3.

[0016] Such as Figure 1 to Figure 3 As shown, the middle frame 2 includes a plurality of middle longitudinal beams 21 connecting the front frame 1 and the rear frame 3, a plurality of middle transverse beams 22 that are arranged on the middle longitudinal beams 21 and are parallel to each other, and are perpendicular to the middle. A plurality of middle support beams 23 of the longitudinal beam 21 and a plurality of middle reinforcing beams 24 intersecting between the middle cross beams 22 are arranged. The plurality of middle longitudinal beams 21 include a plurality of m...

Abstract

The invention discloses a pure electric vehicle frame. The pure electric vehicle frame comprises a front frame, a middle frame and a rear frame, the middle frame comprises a plurality of girders connecting the front frame and the rear frame, a plurality of parallel beams arranged on the girders, a plurality of supporting beams perpendicular to the girders and a plurality of stiffening beams crosswise arranged among the beams; the girders comprise a plurality of upper girders and a plurality of lower girders respectively arranged on two sides of the middle frame, the plurality of the upper girders are fixedly arranged above the plurality of the lower girders respectively through the supporting beams, and the plurality of girders, beams, supporting beams and stiffening beams are all square steel tubes. The pure electric vehicle frame design has the advantages that the square steel tubes are used for overlapping grid surfaces in the middle portion, installation space is saved for power batteries, floor frames of the vehicle body portion are replaced by vehicle frame upper layer square steels, internal height of the vehicle body is increased, and weight of the whole vehicle is also decreased.

Description

Technical field: [0001] The present invention relates to the field of automobile technology, in particular to a pure electric automobile frame. Background technique: [0002] At present, in order to solve the problem of automobile exhaust polluting the atmosphere, people are committed to the research and development of low-energy and small-displacement automobile engines on the one hand, and on the other hand, they have begun to study the use of electric motors instead of gasoline engines to manufacture electric vehicles. With the continuous improvement of battery technology and electric motor technology, more and more people pay attention to electric vehicles. [0003] At present, pure electric vehicles of 6-7 meters above the market basically adopt three types of chassis, and the frame of the third type of chassis is a beam structure that runs through the front and rear. Although the beam structure is strong, it increases the weight of the vehicle and also takes up a lot of spac...
