Miniature purely electric car chassis layout structure

Abstract

The invention discloses a miniature purely electric car chassis layout structure, which comprises a square truss, wherein the square truss is convex to a passenger cabin, the front part of the square truss is fixedly arranged on a middle transverse beam of a car body, the back part of the square truss is fixedly arranged on a back transverse beam of the car body, a power battery pack assembly is arranged in the square truss, a low-voltage module is arranged in a front cabin skeleton, a high-voltage power module is arranged in a back cabin skeleton, and a cooling water pipe, a brake steel pipe and a parking brake flexible shaft are arranged at the two sides of the power battery pack assembly. The miniature purely electric car chassis layout structure has the advantages that the layout spaces of high-voltage and lower-voltage electric appliances of the electric car are independently arranged, so the electromagnetic interference is reduced; the battery pack is arranged by the new regular framework type truss, so while the safety ground clearance of the battery is guaranteed, the trafficability of the whole car and the comfortability of passengers are guaranteed, the capacity of a battery of the battery pack is increased, and the driving mileage of the whole car is increased; the power driving system assembly adopts the rear drive back layout method, so the climbing capability of the miniature purely electric car is effectively improved, and the front axial load and back axial load of the whole car reach the ideal distribution ratio of 50:50.

Description

technical field [0001] The invention relates to the technical field of automobile chassis layout structure, in particular to a pure electric mini car chassis layout structure. Background technique [0002] At present, with the transfer of the national automobile industry technology route to new energy vehicles, the focus is on the development of pure electric vehicles, especially the special financial subsidies for pure electric vehicles, which have promoted the development and industrialization of pure electric vehicles. Before the present invention was proposed, due to the influence of the resources of the existing traditional vehicle platform, most automobile manufacturers mostly used the original fuel vehicle platform, canceled the engine, transmission, and fuel tank, and simply replaced them with drive motors and reducers. The lower part of the body floor or the power battery pack. The patent No. CN202827102U discloses a pure electric minibus chassis layout structure. ...

AI Technical Summary

Problems solved by technology

The patent No. CN202827102U discloses a pure electric minibus chassis layout structure. In this patent, the battery pack is arranged in the middle of the bottom of the car, but the periphery is not covered, the stability of the battery pack is not high, and because the battery pack is arranged on the body Under the bottom plate, the ground clearance is very low. It is easy to underpin on bumpy roads and impact with the bottom of the battery pack, which is prone to accidental risks such as damage and fire. At the same time, the irregular shape of the battery pack makes it difficult to check and maintain

And the patent does not describe the installation and layout positions of major system components such as steering and braking
