Electric vehicle frame and manufacturing method thereof

Abstract

The invention provides an electric vehicle frame and a manufacturing method thereof, and belongs to the technical field of electric vehicles. The problems of heavy weight and troublesome manufacture of an existing electric vehicle frame are solved. The electric vehicle frame includes a bottom plate, wherein the circumferential edges of the bottom plate bends downwards to form a surrounding edge, and the bottom plate and the surrounding edge are made of aluminum alloy materials and are of an integral structure; in the front-rear direction of an electric vehicle, the bottom plate comprises a front end part used for being connected with a handlebar tube, a foot stepping part and a rear tail part used for installing a seat barrel, and in the front-rear direction of the electric vehicle, the rear tail part is obliquely and upwards raised relative to the foot stepping part; and the connection position of the foot stepping part and the rear tail part is provided with a strengthened protrusionprotruding upwards. The manufacturing method of the electric vehicle frame comprises the step that all parts of the vehicle frame are formed into a whole in a stamping mode. The electric vehicle frame has the advantages that the lightweight of the vehicle frame is realized, meanwhile the strength of the vehicle frame is not lowered, and the manufacturing efficiency of the vehicle frame is high.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to an electric vehicle frame and a manufacturing method of the frame. Background technique [0002] Electric vehicles, that is, 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] An electric vehicle includes a frame, an existing electric vehicle frame, such as a frame of an electric vehicle disclosed in Chinese patent documents [Application No.: 201910093536.5; Application Publication No.: CN109552544A], which includes a head pipe, a top end and a head pipe The front main pipe joined by the rear surface of the car body, the front main pipe bends backward at the bottom of the car...

AI Technical Summary

Problems solved by technology

[0004] The weight of the steel structure and stamping parts is heavy, which makes the frame of this structure heavy, so that the weight of the electric vehicle with this structure is about 70kg. The weight of the electric vehicle itself is heavy, which will accelerate the battery consumption when driving. The battery life of the electric vehicle with this structure is 50km-70km, and the battery life is relatively short; moreover, there are many plastic parts in the body, and the plastic parts are easy to change color, age and break, resulting in low overall strength of the electric vehicle, and the plastic parts are flammable items , a great security risk
