Novel electric tricycle frame

Abstract

The invention relates to a novel electric tricycle frame. The novel electric tricycle frame comprises a U-shaped main framework (12) formed by bending one pipe, bent portions are formed in the middle of the main framework (12) in a compression mode, the main framework (12) is divided into a front framework body and rear framework bodies, and the front framework body is lower than the rear framework bodies in the vertical direction, so that a step shape is formed. A tail crossbeam (2) is erected between the tail ends of the rear framework bodies in a fixedly connected mode, and a first middle crossbeam (4) is erected between the middles of the rear framework bodies in a fixedly connected mode. The novel electric tricycle frame further comprises a main crossbeam (6) formed by bending one pipe, the middle of the main crossbeam (6) is located in the front framework body of the main framework (12) and fixedly connected with the front framework body of the main framework (12) through a head crossbeam (14), the rear end of the main crossbeam (6) is bent upwards and fixedly connected with the middle of the first middle crossbeam (4), the front end of the main crossbeam (6) is bent and extends obliquely, forwards and upwards to form a front oblique beam, and the top end of the front oblique beam is fixedly connected with a front forked pipe (10).

Description

technical field [0001] The invention belongs to the technical field of tricycle parts, in particular to a novel electric tricycle frame. Background technique [0002] The frame of the electric tricycle is the skeleton of the whole vehicle. The quality of its structure directly determines the structural strength of the whole vehicle, and the complexity of its structure directly determines the efficiency of production and processing. The frame of an electric tricycle generally includes an upper frame body and a lower frame body. The front end of the upper frame body is fixedly connected with the rear end of the lower frame body. Take the space of the foot of the person. In the prior art, the upper frame and the lower frame are generally fixedly connected by a plurality of vertical connecting rods, the upper ends of the connecting rods are welded to the upper frame, and the lower ends are welded to the lower frame. The frame of the electric tricycle with the above-mentioned s...

AI Technical Summary

Problems solved by technology

[0004] The frame of the above-mentioned electric tricycle has the following defects: the upper frame and the lower frame are still obtained by the processing technology of split forming and welding connection, which does not fundamentally reduce the number of welding parts, the processing procedure is complicated, and the overall strength of the frame is difficult to guarantee
