Embodiment Construction

[0033] Such as figure 1 , figure 2 and Figure 4 As shown, the lightweight electric vehicle of this embodiment includes a body structure 1 of the electric vehicle and a frame structure 2 connected to the lower part of the body structure 1. The body structure 1 includes a body 1-1 and a door 1-2. The body 1-1 and the door 1-2 are composed of a framework 1-3 and a thermoplastic plate (not shown in the figure) covering the inner and outer surfaces of the framework; Composition: A battery compartment 2-2 is provided in the middle of the beam frame 2-1. Of course, as a lightweight electric vehicle, it also includes power supply, drive motor, motor speed control device, transmission device, driving device, steering device, braking device, etc. in the prior art.

[0034] Because the technical solution adopts the technical means that the body and the door are composed of a skeleton and a thermoplastic plate covering the surface of the skeleton, it can not only ensure the strength,...

Abstract

The invention discloses a lightweight electric vehicle which comprises a vehicle body structure of the electric vehicle and a frame structure connected with the lower portion of the vehicle body structure. The vehicle body structure comprises a vehicle body and a vehicle door, wherein the vehicle body and the vehicle door are composed of a skeleton and thermoplastic boards, wherein the thermoplastic boards cover the inner surfaces and the outer surfaces of the skeletons. The skeleton is composed of a plurality of stamping rod parts which are welded to form a cage-shaped vehicle body skeleton in an integral mode. The surface of the cage-shaped vehicle body skeleton is provided with threaded fixing holes for fixing the thermoplastic boards which are fixedly connected with the cage-shaped vehicle body skeleton through screws and form a whole closed vehicle body. A body of the vehicle frame structure is composed of a crossbeam frame. A battery bin is arranged in the middle of the crossbeam frame. According to the lightweight electric vehicle, strength, rigidity and safety of the vehicle body and the vehicle door can be ensured, the weight of the vehicle body and the weight of the vehicle door can also be obviously relieved, strength and rigidity of a chassis can be effectively improved, when four wheels are stressed unevenly, the vehicle body will not deform, and batteries can be arranged in the most safe position.

Description

technical field [0001] The invention relates to a passenger vehicle, in particular to a lightweight electric vehicle. Background technique [0002] Electric vehicles refer to vehicles powered by vehicle-mounted power supplies, driven by electric motors to drive wheels, and meeting the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. [0003] Compared with internal combustion engine vehicles, electric vehicles have many characteristics of their own. Among them, the most notable point is that the power of electric vehicles is small, and the carrying capacity is greatly limited. In order to improve the carrying capacity of electric vehicles, reducing the weight of the vehicle body is one of the effective methods. However, in the prior art, the body and doors of electric vehicles are all stamped from steel plates. To reduce...
