Embodiment Construction

[0035] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0036] Such as Figure 1-3 As shown, the vehicle frame includes two symmetrically arranged vehicle frame main girders 11, and the vehicle frame main girders 11 are directly cut and made from pipe materials.

[0037] Its outer diameter of two vehicle frame girders 11 is equal to pipe wall wall thickness.

[0038] By directly cutting the pipe, it not only improves the production efficiency, but also reduces the manufacturing cost.

[0039] In addition, the pipe material is a metal pipe material, which is convenient for subsequent welding processing.

[0040] The front ends of the two frame girders 11 are bent upwards and converged to be connected to the front insertion pipe 12 . That is, the front ends of the two frame main beams...

Abstract

The invention provides a frame which comprises two symmetrically arranged frame girders, wherein the front ends of the two frame girders are upward bent and mutually converged and connected on a vehicle head insert tube; the rear ends of the two frame girders are upward bent and mutually converged and connected on a seat stand; the rear ends of the two frame girders are connected with wheel connecting racks, and damping components are respectively arranged between the wheel connecting racks and the rear ends of the frame girders; the rear ends of the frame girders, the wheel connecting racks and the damping components are connected to form a triangular structure; a front reinforced structure is arranged between the front ends of the two frame girders; a rear reinforced structure is connected between the rear ends of the two frame girders; a battery storage device positioned between the front reinforced structure and the rear reinforced structure is arranged between the middle parts ofthe two frame girders; and the upward bent direction of the front ends of the frame girders is opposite to the upward bent direction of the rear ends of the frame girders, and an included angle greater than 90 degrees is formed between the front ends of the frame girders and the rear ends of the frame girders.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a vehicle frame and an electric vehicle thereof. Background technique [0002] The structure of an electric vehicle generally includes a frame, front and rear wheels, and a battery. [0003] And especially some electric vehicles with wider wheels. It requires the frame to have very good structural strength. [0004] However, in order to be able to solve the above-mentioned technical problems, many existing inventors have provided a vehicle frame with a very complicated structure. Although it can meet the requirements of structural strength, the production efficiency is low due to the relatively complicated structure. At the same time, the shock absorption of the vehicle is poor. [0005] In order to solve this technical problem, for example, Chinese patent literature discloses an electric scooter [application number: 201520494603.1], which includes a fron...
