Description

An electric vehicle frame structure

technical field

The utility model belongs to the technical field of electric vehicles; in particular, it relates to a frame structure of electric vehicles.

Background technique

With the world's energy shortage and environmental protection requirements, gasoline and diesel vehicles are subject to certain restrictions and impacts. Electric vehicles will be the main direction of the industry. The battery packs of several hundred kilograms in electric vehicles cannot be directly installed on the front floor. In fact, because it will not only increase the weight of the electric vehicle body, but also directly affect the cruising range of the electric vehicle, and the traditional electric vehicle frame structure is complex, difficult to disassemble, labor-intensive for workers, and low production efficiency.

Contents of the invention

The purpose of the invention of the utility model is:

The main purpose is to solve the technical problems of complex structure of the electric vehicle frame, heavy weight, inconvenient battery disassembly and installation, and low torsional strength.

The technical scheme of the utility model is:

Provided is an electric vehicle frame structure, comprising a seat installation beam, a left door sill longitudinal beam and a right door sill longitudinal beam are respectively arranged on both sides of the seat installation beam, a middle floor is arranged at the lower part of the seat installation beam, and the seat The front end of the chair installation beam is provided with a front crossbeam, the front crossbeam is provided with a front longitudinal beam one and a front longitudinal beam two, a front baffle is arranged on the front longitudinal beam one and a front longitudinal beam two, and the rear end of the seat installation beam The first rear longitudinal beam and the second rear longitudinal beam are arranged, the first rear longitudinal beam and the second rear longitudinal beam are connected with the rear cross beam at the rear end of the seat installation beam and then connected with the middle rear panel, and two longitudinal The reinforced beams used in the frame structure of the electric vehicle are made of aluminum alloy for the beam and the longitudinal beam structure.

Technical effect of the present utility model:

The utility model effectively solves the technical problem that the frame body of the electric vehicle is heavy and reduces the cruising range, and has a simple structure, convenient installation by workers, high production efficiency and low labor intensity.

Description of drawings

Fig. 1 is the structural representation of the utility model;

In the figure, 1 is the front baffle; 2 is the first front longitudinal beam; 3 is the left door sill longitudinal beam; 4 is the seat installation beam; 5 is the middle floor; 6 is the first rear longitudinal beam; 7 is the second front longitudinal beam; 8 9 is the right door sill longitudinal beam; 10 is the rear cross beam; 11 is the rear longitudinal beam two; 12 is the middle and rear plate; 13 is the reinforcing beam.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a frame structure of an electric vehicle is provided, including a seat mounting beam 4, a left door sill longitudinal beam 3 and a right door sill longitudinal beam 9 are respectively arranged on both sides of the seat mounting beam 4, and The bottom of the beam 4 is provided with a middle floor 5, and the front end of the seat installation beam 4 is provided with a front beam 8, and the front beam 8 is provided with a front longitudinal beam 1 2 and a front longitudinal beam 2 7. The second longitudinal beam 7 is provided with a front baffle plate 1, and the rear end of the seat installation beam 4 is provided with a rear longitudinal beam 6 and a rear longitudinal beam 2 11, and the rear longitudinal beam 1 6 and the rear longitudinal beam 2 11 are installed with the seat. After the rear cross beam 10 at the rear end of the beam 4 is connected, it is connected with the middle and rear board 12, and two longitudinal reinforcement beams 13 are arranged at the middle passage of the middle floor 12, wherein the left and right door sill longitudinal beams, rear longitudinal beams, front and rear cross beams, etc. The formed frame is used to fix the battery pack, and these structural parts are also part of the main structure of the car body. There are two reinforced longitudinal beams in the middle floor channel, which are welded with the front and rear crossbeams and welded with the middle floor, left and right door sill longitudinal beams at the same time to form the structural parts of the seat. The crossbeams used in the frame structure of electric vehicles The material of the longitudinal beam structure is aluminum alloy. The utility model is simple and convenient. It expands the layout of the electric vehicle frame very concisely, makes the layout more reasonable, and facilitates the placement of large-capacity batteries. Moreover, the frame structure is light in weight and will not It brings a large load to the vehicle running system, high production efficiency in the process of processing, simple installation and disassembly, and low labor intensity for workers, which is very suitable for promotion in electric vehicles.
