[0002] Electric vehicles have the advantages of zero emissions, low noise, high cost-effectiveness in operation and maintenance, and are becoming more and more popular among users. The energy used by electric vehicles is the electricity provided by the battery packs on board. Electric vehicles need to be charged after the electricity is used up. The battery packs of electric vehicles are generally divided into fixed and replaceable types. Among them, fixed battery packs are generally fixed on the vehicle, and the vehicle is directly used as the charging object when charging. The replaceable battery packs are generally fixed on the bracket of the vehicle through a movable installation method. The battery pack can be removed for replacement or charging operations separately. After the replaced battery pack is charged, it is installed on the vehicle.

[0003] The battery box serves as the shell of the battery pack, which is used to accommodate and protect the battery cells and related electrical components, and to shield the battery pack performance from possible damage caused by water mist, air, and debris in the external environment.

[0004] At present, electric vehicles on the market use metal battery boxes, which not only increase costs, but also increase the weight of the vehicle body, reducing the endurance of electric vehicles. In addition, metal materials cannot keep the battery warm in winter, which will also affect the endurance of electric vehicles. Utility Model Content

[0005] The utility model aims to provide a PE modified rotational molding constant temperature system battery box, which reduces the weight of the vehicle body and reduces the influence of the external temperature on the battery, thereby increasing the endurance of the electric vehicle.

[0007] Two card slots penetrating the bottom of the box are arranged on the outer side of the bottom of the box;

[0008] The inner edge of the opening side of the box body is provided with a convex edge connected with the cover body.

[0009] Preferably, a plurality of evenly arranged and inwardly recessed reinforcing rib structures are provided on the box body.

[0010] Preferably, a plurality of screw holes are provided on the connection block 1 for screwing with the second-layer bracket.

[0011] Preferably, the clamping groove is clamped with the automobile beam.

[0012] Preferably, a plurality of screw holes 2 connected to the automobile castings are arranged on the reinforcing rib structure at the bottom of the box body.

[0013] Preferably, a second connection block for external electrical connection is reserved on the side of the box body.

[0014] Therefore, the utility model adopts a PE modified rotational molding constant temperature system battery box with the above structure, which has the following technical effects:

[0015] (1) The utility model is a PE modified rotational molding one-piece molding, the material can effectively reduce the impact of external temperature on the battery, and prevent the external low temperature in winter from affecting the battery life;

[0016] (2) The material of the utility model can effectively reduce the weight of the vehicle body. In actual tests, the weight of a battery box of the same volume is reduced by at least 60KG, effectively increasing the vehicle's endurance.
