Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] see figure 1 and figure 2 As shown in the matching structure between the battery pack and the vehicle body of an electric vehicle, the battery pack 3 is arranged at the central position under the floor of the vehicle body, the front end is directly below the instrument panel, and the rear end is close to the trunk 1. In this way, the battery pack 3 can be fully utilized. This part of the space after the gas system is removed; the front protrusion 6 on the front of the battery pack 3 corresponds to the underside of the middle channel 2 on the body floor, and the rear protrusion 7 on the rear of the battery pack 3 corresponds to the position of the rear seats. The bottom of 4 corresponds; the battery pack 3 is connected to the body floor by bolts, so that the battery pack and the body floor are closely attached.

[0020] Further, an air inlet pipe is provided on the...

Abstract

The invention discloses a matching structure of an electric car battery pack and a car body, which is characterized in that: the battery pack is arranged on a central position below a car body floor, the front end of the battery pack is arranged right below an instrument console, and the rear end of the battery pack is close to a trunk; a front projection on the front part of the upper surface of the battery pack corresponds to the lower surface of an middle passage on the car body floor, and a rear projection on the rear part of the upper surface of the battery pack corresponds to the lower surface of a rear seat position; and the battery pack is connected with the car body floor through bolts. The upper surface of the battery pack is provided with an air inlet pipe, and two side surface of the battery pack are respectively provided with an exhaustion pipe. Due to the adoption of the matching structure, a low-temperature heating function and a high-temperature heat radiation function of the battery pack can be realized; the battery pack effectively utilizes the space on the lower part of the floor and is completely bonded with the car body, so the load of a front axle and a rear axle of the car can be uniformly distributed; and the requirements that the capacity design of the battery pack is maximized and the car body modification is minimized can be satisfied, and the matching structure also has the advantages of convenience in installation and disassembling and the like.

Description

technical field [0001] The invention relates to a power battery of an electric vehicle, in particular to a matching structure between a battery pack and a vehicle body of an electric vehicle. Background technique [0002] With the pollution of the earth's environment and the appearance of the energy crisis, it is more urgent to study an energy-saving and environment-friendly vehicle that can alleviate the energy pressure and reduce environmental pollution. Pure electric vehicles can just meet these functions, and they can achieve zero emissions and no pollution. However, in the development process of pure electric vehicles, the layout of power battery packs is a difficult point. Due to the large number of traditional auto parts, there is no space for the installation of power battery packs without a large number of body changes. Some of the existing hybrid electric vehicles or pure electric vehicles put the power battery pack in the trunk, and some put it in the front cabi...
