Problems solved by technology

At present, many modified vehicles in China put the battery in the spare tire or trunk of the vehicle, which is very unreasonable
The battery occupies the position of the spare tire so that the whole vehicle has no space to store the spare tire, and the most important thing is that the lithium battery has a higher energy. Compared with the fuel tank, the safety of rear collision must also be paid attention to. A short circuit will cause the battery to fail, and in severe cases, the battery will catch fire and explode
It can be seen that the collision safety of the battery placed in the spare tire and trunk of the vehicle cannot be guaranteed, and the driver's driving safety is at a high risk

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] see figure 1 , figure 2 , the battery pack 2 is rectangular as a whole, and is in the shape of a ladder with one end high and the other end low, its high end is arranged in the height space 10 miles under the rear seat floor 3, and its short end is arranged under the front cab seat floor . Because the battery pack is arranged under the chassis of the car, the central pipeline 1 of the original car and the hand brake mechanism 4 of the traditional car are retained, and the hand brake wiring harness 4 is drawn from the two ends of the rear row base 3 transversely.

[0024] The central duct 1 of the original car is used to set up the battery heat dissipation air duct, and the three air inlets 5 on the battery pack are arranged longitudinally and correspondingly below the central duct 1, and the two air outlets 6 are arranged horizontally and correspondingly at ...

Abstract

The invention provides a mounting structure for a power battery pack of an electric automobile. The battery pack is rectangular, has a step shape with one higher end and the other lower end and is arranged below an automobile chassis; the higher end of the battery pack is arranged in a high space below a rear-seat bottom board; the lower end of the battery pack is arranged below a front-seat cab bottom board; an air inlet longitudinally formed in the middle of the lower end of the battery pack is positioned below a central pipeline; and two exhaust fans which are transversely arranged at the higher end of the battery pack are correspondingly arranged below the rear seat. The battery pack is positioned between a body transverse beam and a body longitudinal beam; lugs are respectively arranged on two longer sides and two shorter sides of the battery pack; and lug connecting blocks are respectively arranged on the body transverse beam and the body longitudinal beam correspondingly and are fastened and assembled through bolts so as to fix the battery pack on the automobile body. On one hand, the structure solves the problem of the contradiction between volume requirement and the arrangement space of the power battery and the contradiction between the large complete-automobile modification and reduction of man-machine comfort; on the other hand, the structure meets the requirement of the battery on complete automobile collision safety.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle application, and in particular relates to an installation structure of a power battery pack of an electric vehicle. Background technique [0002] Pure electric vehicles have the advantages of not relying on petroleum resources, zero emissions, low cost of use, and can stabilize the low power consumption of the grid, but they also have the problem of insufficient driving range. Although the development of plug-in hybrid cars has solved this problem , but because it is equipped with a range-extended fuel system, the battery layout space is narrower, and the added muffler and fuel tank also bring new difficulties to the battery layout. Although the lithium-ion power battery technology has made a breakthrough, the current technology still has the characteristics of large size, heavy weight and difficult layout in terms of meeting the needs of the whole vehicle. [0003] For traditional cars,...
