Embodiment Construction

[0023] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0024] Such as Figure 1-11As shown, the present invention is a front, middle and rear three-stage structure electric vehicle frame, which includes a front frame, a middle frame and a rear frame, and is characterized in that: the front frame, the middle frame and the rear frame The upper frame is assembled from three parts and adopts a platform structure. The front frame is formed by welding a plurality of round tube beams and sheet metal parts. The first front frame main beam 4 is welded to the second front frame main beam 5. One end of the second front frame main beam 5 Welded with the first front frame main beam 4, the other end of the second front frame...

Abstract

The invention provides an electric vehicle frame with a front-middle-rear three-section type structure, which comprises a front skeleton, a middle skeleton and a rear skeleton, is formed by splicing the front skeleton, the middle skeleton and the rear skeleton, adopts a platform-type structure, and is formed by splicing the front skeleton, the middle skeleton and the rear skeleton by high-strength bolts; a first side wall skeleton, a second side wall skeleton and a third side wall skeleton of the middle skeleton and the section of a cross beam of a vehicle body form a honeycomb structure; and the middle skeleton formed by the three side wall skeletons has an elliptical structure. The vehicle body skeleton of the electric vehicle has novel design and a reasonable structure, is convenient to manufacture, and easy to achieve mass industrial batch production, can effectively reduce the weight of the vehicle body due to the honeycomb type structure of the middle skeleton, meanwhile, can effectively absorb power generated by collision when the vehicle is collided, and improves the safety performance of the whole vehicle. The electric vehicle frame is applied to the electric vehicle, and can be widely used in the fields such as urban riding, tour and sightseeing and police patrolling.

Description

technical field [0001] The invention relates to an automobile body frame, in particular to a novel electric automobile body frame. Background technique [0002] As we all know, the development of electric vehicles has a history of 173 years. Due to its characteristics of low environmental pollution, low noise and high energy utilization efficiency, it has been paid more and more attention by countries all over the world. As one of the main components of electric vehicles, the body frame basically belongs to the overall structure from the perspective of the current popular electric vehicle structure in the market. Its body structure is complex and inconvenient for production and assembly. Simple production and assembly requirements. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art, and provide a body frame of an electric vehicle with novel and reasonable design, reasonable structure, standardized process, c...
