Tenon and mortise type vehicle frame for battery pack of electric vehicle

Abstract

The invention discloses a tenon and mortise type vehicle frame for a battery pack of an electric vehicle. The tenon and mortise type vehicle frame comprises a tenon and mortise type vehicle frame structure, a battery box body, an air cooling heat dissipating structure and a vehicle body floor, wherein the tenon and mortise type vehicle frame structure is fixed at the lower part of the vehicle body floor, and the air cooling heat dissipating structure is fixed at the upper part of the vehicle body floor; the tenon and mortise type vehicle frame structure is a framework structure spliced from four tenon opening pipes through tenon opening connectors, and foamed aluminum is stuffed in the tenon opening pipes; the battery box body is fixed on the inner part of the framework structure; the air cooling heat dissipating structure comprises an air duct body and a heat pipe group, and the air duct body is fixed at the middle part of the vehicle body floor. According to the tenon and mortise type vehicle frame provided by the invention, under the premise that requirements of the strength and the rigidity of the vehicle body structure of the electric vehicle and the collision effect are satisfied, the safety problem of the battery pack of the electric vehicle is comprehensively solved, the tenon and mortise type vehicle frame has the advantages of collision safety property, heat safety property, bottom impact resistant property, water resistance and dust resistance, and the tenon and mortise type vehicle frame is convenient to dismount and mount.

Description

technical field [0001] The invention relates to an electric vehicle frame structure, in particular to a mortise and tenon type vehicle frame of an electric vehicle battery pack. Background technique [0002] Under the background of energy conservation and emission reduction today, electric vehicles have become one of the mainstream directions for the development of new energy vehicles due to their advantages of zero emission, no pollution, high efficiency, and good power. However, cruising range and battery safety have always been two major shortcomings restricting the development of electric vehicles. The driving range is mainly related to two factors: curb quality and battery capacity. The energy density near the development bottleneck and the high battery cost limit the battery capacity of electric vehicles. Large capacity also means an increase in curb quality, blindly increasing the battery capacity. Capacity does not solve the problem of cruising range. In mainstream...

Problems solved by technology

The third type has the most obvious lightweight effect, but it has high requirements on cost and production, and is only used in high-end cars and sports cars

The first type is the current mainstream electric vehicle body application form, but the weight reduction effect is very limited, and the body and battery are designed separately, and the safety of the battery is not considered at the core of the body design.

The second type of frame scheme is used by some low-speed electric vehicles, but most of them are pipe-beam structures welded by steel pipes, which have not improved in terms of light weight and structural safety.
