Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a battery pack box for a new energy vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Batteries are the main output power, so battery packs are needed to protect the batteries.

[0003] In the prior art, since the battery pack is a consumable item, it needs to be disassembled and replaced after a period of use. The common battery pack box cover is fixed by bolts, and a large number of screws need to be removed and installed during disassembly and assembly. The disassembly and assembly steps are relatively cumbersome, which affects the replacement efficiency of new energy vehicle batteries. Therefore, it is necessary to propose a new type of new energy vehicle battery pack box. Utility Model Content

[0006] Preferably, the mounting rod slides through the fixing frame, and the top of the round block fits against the bottom of the cover, so that the mounting rod slides upward in the fixing frame under the action of the spring's rebound force, driving the round block to contact the bottom of the cover to prevent the cover from shaking.

[0007] Preferably, blocks are symmetrically arranged on the top of the frame, and the inner surfaces of the two blocks are fixedly connected to the rotating rod, so that when the rotating rod rotates, the blocks will be driven to rotate to one side to block or release the cover.

[0008] Preferably, the outer surfaces of the two rotating rods are rotatably connected to the inner surface of the frame, and the tops of the two rotating rods are fixedly connected to the rotating blocks. By setting a rotating block with a large cross-section, it is convenient for people to rotate the rotating rods in the frame, so that the block follows the rotation.

[0009] Preferably, arcuate grooves are symmetrically provided on the top of the cover near the two side edges, and the arcuate grooves are matched with the stoppers so that the stoppers can be easily limited in the arcuate grooves when they rotate toward the top of the cover.

[0010] Preferably, a plurality of first weight-reducing grooves are equidistantly provided on the front and rear outer surfaces of the frame, and the inner surfaces of the plurality of first weight-reducing grooves are fixedly connected to reinforcing ribs. By providing a plurality of first weight-reducing grooves on the surface of the frame, the overall weight is greatly reduced, and by arranging reinforcing ribs in the inner grooves, the strength of the box is increased.

[0011] Preferably, second weight-reducing grooves are provided on the outer surfaces of both sides of the frame, and a plurality of heat dissipation holes are evenly provided on the inner surfaces of the two second weight-reducing grooves. The heat dissipation holes are connected to the frame. By providing second weight-reducing grooves on both sides of the frame, the weight of the box is further reduced, and the heat dissipation holes evenly provided in the inner grooves are connected to the box, which facilitates heat dissipation inside the box.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the utility model, when in use, through the cooperation of the limit assembly, by pressing the cover downward, it pushes the multiple round blocks downward, forcing the multiple springs to deform and contract, making it easy to rotate the two blocks into the two arc-shaped grooves, and use the rebound force of the multiple springs to push the cover upward in the opposite direction until it hits the bottom of the two blocks, playing a clamping and fixing role, and rotating the two rotating blocks outward in turn to drive the two blocks to rotate out of the two arc-shaped grooves, so that personnel can quickly remove the cover and open the battery pack box to maintain and replace the internal batteries, thereby improving the replacement efficiency of new energy vehicle batteries.

[0014] 2. In the present invention, when in use, the overall weight of the battery pack box can be greatly reduced by respectively opening a first weight-reducing groove and a second weight-reducing groove on the outer surface of the frame. The strength of the frame is improved by arranging reinforcing ribs in the first weight-reducing groove. The heat dissipation inside the battery pack box is facilitated by opening a plurality of heat dissipation holes in the second weight-reducing groove, and the utility model has high practicality.
