Description

Combined automobile battery frame Technical Field The utility model relates to the technical field of automobile batteries, in particular to a combined automobile battery frame. Background With the widespread use of electric vehicles and other energy storage devices, the design and manufacture of battery frames is subject to increasing demands, especially in terms of balance of strength and weight, complexity of the processing process, and cost control. The traditional battery frame mostly adopts all-steel rolling parts or aluminum alloy sections. The battery frame of the all-steel rolling part has the advantages of low raw material price, high material strength, excellent welding performance, less carbon emission and the like, an integrally rolled mesh-shaped structure is often adopted to meet the strength requirement, but the manufacturing cost of the mesh-shaped rolling tool is high, transverse ribs of the mesh-shaped rolling tool are difficult to cut, so that an explosion-proof valve and a connector are difficult to arrange when passing through a frame, and in addition, the battery frame is heavier while the strength requirement is met due to the high density of steel, so that the integral energy density of a battery pack is influenced. The battery frame of the aluminum alloy section has the characteristics of light weight and changeable cross section shape, but the strength and the welding performance of the battery frame are inferior to those of the steel rolling piece. Disclosure of utility model The utility model is used for overcoming the defects of the prior art and providing a combined type automobile battery frame so as to solve the problems mentioned in the background art. In order to achieve the above purpose, the utility model adopts the following technical scheme: The combined type automobile battery frame comprises a frame body, wherein the frame body consists of a battery compartment frame and an element compartment frame; The frame of the frame body is of a three-cavity structure which is arranged up and down, the frame consists of a rolling part and a connecting plate, the rolling part is integrally in a concave shape rotating by 90 degrees and consists of a middle plate, an upper cavity and a lower cavity, the upper cavity and the lower cavity are positioned at two ends of the middle plate, the connecting plate covers the notch of the concave shape and surrounds the rolling part to form a middle cavity, and the connecting plate is respectively connected with the upper cavity and the lower cavity. In the combined automobile battery frame, in the peripheral frame of the frame body, the rolling part is positioned at the outer side of the frame body, and the connecting plate is positioned at the inner side of the frame body. The combined automobile battery frame has the same structure and size as the upper cavity and the lower cavity, and in the height direction, the relation between the height d1 of the upper cavity and the height d2 of the middle cavity is d1/d2 between 1/5 and 1/4. The combined automobile battery frame comprises a frame body, wherein the side face of the frame body is provided with an avoidance hole, the avoidance hole penetrates through a middle cavity, the avoidance hole is formed according to the shape of an explosion-proof valve or a connector, and the dimension of the avoidance hole in the height direction is smaller than the height of the middle cavity. The relation between the width d3 and the height d4 of the frame body of the combined automobile battery frame is d3/d4 between 1/4 and 1/3. Above-mentioned combination formula car battery frame, the frame body outside is provided with the hoist and mount roof beam. Above-mentioned combination formula car battery frame, the cavity wall of connecting plate and two cavities of roller casting die is connected through the rivet. Advantageous effects Compared with the prior art, the utility model has the following advantages: firstly, the frame of the frame body is a three-cavity structure formed by combining a concave-shaped roller pressing piece and a connecting plate, and the upper cavity and the lower cavity of the concave-shaped roller pressing piece can be controlled to be smaller in the height direction, so that the middle cavity is larger in the height direction, the problem that transverse ribs inside the V-shaped structure are difficult to cut and open holes when the traditional all-steel roller pressing piece avoids an explosion-proof valve or a connector, and the problem that the arrangement of the explosion-proof valve and the connector is difficult is solved, and meanwhile, the influence of the cutting transverse ribs on structural strength is avoided. Secondly, the conventional all-steel rolling part adopts a rolling part in a shape like a Chinese character 'mu', as shown in fig. 6, a double-layer steel plate exists on one side wall of the middle cavity, which can bring about weight increase and increase d
