Chassis layout structure of a pure electric miniature car

Abstract

The invention discloses a chassis arrangement structure of a pure electric miniature car, comprising a square truss protruding toward the direction of the passenger compartment, the front part of the square truss is fixed on the middle beam of the vehicle body, the rear part is fixed on the rear beam of the vehicle body, and the power battery pack assembly Arranged in a square truss, the low-voltage module is arranged in the front cabin frame; the high-voltage power module is arranged in the rear cabin frame; cooling water pipes, brake steel pipes and parking brake flexible shafts are arranged on both sides of the power battery pack assembly. The layout space of the high and low voltage electrical appliances of the electric vehicle is independent of each other, which reduces electromagnetic interference. At the same time, a new regular frame truss is used to arrange the battery pack. While ensuring the safety of the battery pack from the ground, it also ensures the passability of the vehicle and the comfort of the passengers. It increases the battery capacity of the battery pack and increases the mileage of the vehicle. The power drive system assembly adopts a rear-mounted and rear-drive layout, which effectively improves the climbing ability of the small pure electric car, and at the same time makes the axle load of the vehicle reach an ideal distribution 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
