Protective shell of electric car range extender and using method of protective shell

Abstract

The invention provides a protective shell of an electric car range extender. The protective shell of the electric car range extender comprises a rubber fixed block, a guide column, a threaded connecting hole, a threaded rod, a positioning trough, an insulating clamping plate, a telescopic rod and a guide sleeve; the rubber fixed block is mounted on the lower end face of the threaded rod, the guide column is fixed to the middle of the interior of the positioning trough, the threaded connecting hole is formed in the middle of the guide column, and the threaded rod is assembled in the threaded connecting hole. According to the design of the protective shell, the rapid positioning and fixing functions of a circuit board are achieved, the positioning groove is formed in the middle of the left end face of the interior of a shell body, the insulating clamping plate is fixed to the left end face of the telescopic rod, the telescopic rod is assembled in the guide sleeve, the guide sleeve is fixed to the middle of the right side end face of the interior of a threading trough, and the fixing function of a circuit is achieved through the design of the protective shell. The invention further provides a using method of the protective shell of the electric car range extender. The protective shell of the electric car range extender is reasonable in structure, high in practicality, convenient to produce and manufacture, good in stability and high in reliability.

Description

technical field [0001] The invention relates to a protective shell for a range extender of an electric vehicle and a method for using the same, belonging to the technical equipment field of electric vehicles. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. [0003] Range-Extender is an additional energy storage component installed on pure electric vehicles to increase the mileage of pure electric vehicles. Usually, users can choose to install or not install it according to the mileage requirements when traveling (reducing the weight of the vehicle can reduce energy consumption)...

AI Technical Summary

Problems solved by technology

[0004] The shell structure of the electric vehicle range extender in the prior art is simple, does not have the positioning and fixing function of the circuit board, which easily causes the displacement of the circuit board and affects the stability of the circuit board during use; the electric vehicle range extender in the prior art The shell cannot fix the line, which can easily cause the line to fall off and the wiring to be chaotic. Therefore, a protective shell for the electric vehicle range extender is urgently needed to solve the above problems
