Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0010] Such as figure 1 with figure 2 The shown electric vehicle body frame includes a body frame body, and the body frame body has side body frames arranged on both sides. The side body frame is divided into a left body frame 3 and a right body frame 1. The roof frame and the front car bracket connected with the right side body frame 1; the left side body frame 3 is composed of the left side body outer piece and the left side body inner side piece which are mortised and jointed, wherein the left side body side outer piece There is a positioning tenon joint, and a positioning mortise eye is provided on the inner part of the left car body. The outer part of the left car body and the inner part of the left car body are mortized and connected by screws; The outer panel and the inner panel on the right side of the body are composed of a positioning mortise joint on the...

Abstract

The invention discloses an electric vehicle body frame which relates to the technical field of electric vehicle manufacture. The electric vehicle body frame comprises an electric vehicle body frame body. The electric vehicle body frame body is provided with side electric vehicle body frames at two sides and an electric vehicle top frame and a front electric vehicle carriage which are connected with the side electric vehicle body frames at the two sides. Each side electric vehicle body frame is composed of a side electric vehicle body outer plate and a side electric vehicle body inner plate which are connected through mortises. The electric vehicle top frame is composed of an electric vehicle top outer plate and an electric vehicle inner plate which are connected through mortises. The front electric vehicle carriage is composed of a front electric vehicle carriage outer plate and a front electric vehicle carriage inner plate which are connected through mortises. Compared with the prior art, the electric vehicle body frame is advantageous in that the integral weight of the electric vehicle body is reduced; strength, consistency and weight of the electric vehicle body frame are respectively better than the strength, the consistency and the weight of the electric vehicle body frame manufactured according to the prior art.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a body frame used for lightening electric automobiles. Background technique [0002] Facing the dual pressure of energy crisis and environmental pollution, electric vehicles have become a hot spot for global development. The current difficulties faced by the development of the electric vehicle industry are low payload efficiency, and most of the energy is consumed in moving non-payloads. Lightweight technology can increase the payload rate by reducing its own weight, thereby extending the driving range, especially when the current power battery cost is high and the energy storage level is insufficient, it is of great significance to promote the industrialization of electric vehicles. At present, most of the research on the lightweight of electric vehicles by automobile manufacturers is limited to the development of single-sided body panels. How to upgrade from s...
