Frame structure of electric vehicle

Abstract

The invention relates to a frame structure of an electric vehicle. The structure comprises a main beam, a frame vertical pipe fixed on the main beam, and a main frame fixedly connected with the main beam, wherein the main frame mainly comprises a left main pipe and a right main pipe, and is characterized in that the main frame comprises a front part fixed with the main beam and horizontally arranged, a middle part and a rear part integrally formed on the front part and sequentially obliquely arranged, a battery box frame is fixedly arranged at the front part of the main frame; a flat fork is connected to the lower end of the middle of the main frame through a flat fork shaft; upper shock absorption mounting frames are respectively arranged on the inner sides of the rear parts of the left main pipe and the right main pipe, lower shock absorption mounting frames are respectively arranged at the upper parts of both sides of the rear part of the flat fork, and a rear shock absorption pieceis arranged between the upper shock absorption mounting frames and the lower shock absorption mounting frames; and a side bracket connecting plate is fixedly arranged outside the front part of the left main pipe, and a side bracket mounting plate is mounted on the side bracket connecting plate in a covering manner. The structure is beautiful in appearance, simple in structure, good in damping effect, and convenient for production and manufacture.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle frame structure. Background technique [0002] Electric vehicles use batteries as power sources, which are light and environmentally friendly. In daily life, more and more people choose electric vehicles as a means of transportation. The side bracket mounting plate on the traditional electric vehicle frame is directly welded on the frame, but because the side bracket mounting plate of most models is exposed, which affects the appearance, it cannot meet the requirements of some high-end customers for the appearance of the vehicle; the traditional electric vehicle The upper installation point of the rear shock absorber is to connect a beam directly under the left and right main pipes or between the left and right main pipes for welding the rear shock absorption upper mounting bracket. Due to the structural limitations of some models, this structure can...
