[0002] The new energy battery plastic frame is a complete frame structure, usually injection molded in one piece. Its internal design has cavities or grooves that match the shape and size of the energy storage battery to place and fix the battery cells or battery modules. It can tightly wrap the battery and provide good protection. The battery plastic frame has high structural strength and can effectively protect the battery from external impacts and vibrations. At the same time, the high fitting precision with the battery can ensure the stability of the battery in the frame.

[0003] In existing technologies, the commonly used battery plastic frame structure has a sealed structure at both the top and bottom of the outer wall. The upper and lower cover structures of the plastic frame can limit and fix the battery after being closed. Therefore, in order to ensure the protection effect and the stability of fixing the battery, the upper and lower cover structures of the plastic frame are usually closed structures, or only have some small holes for heat dissipation. However, this method may not be able to meet the heat dissipation efficiency when the environment is too stable and high, which will cause the battery to overheat and affect its charging and discharging efficiency and capacity. Therefore, it is not conducive to extending the battery's service life, so there are still some shortcomings.

[0004] In conclusion, it is necessary to invent a plastic frame structure for new energy storage batteries. Utility Model Content

Side connecting blocks 400 are fixed at corresponding positions on the outer side of the plastic frame bottom mold 100 and the plastic frame top cover 500. Two adjacent side connecting blocks 400 are fixedly connected by bolts. After the personnel align the plastic frame bottom mold 100 and the plastic frame top cover 500, the side connecting blocks 400 can be aligned together. Then, the personnel can fix the side connecting blocks 400 with bolts so that the plastic frame bottom mold 100 and the plastic frame top cover 500 can be fixed.

[0025] Battery-side fixing mechanisms 300 are provided at the bottom inner wall of the plastic frame bottom mold 100 and on both sides of the energy storage battery body 200. Side clamping blocks 210 are provided on both sides of the inner wall of the plastic frame bottom mold 100. These side clamping blocks 210 are placed on both sides of the outermost energy storage battery body 200 to clamp it. The side clamping blocks 210 can be made of high-hardness rubber. The 0 includes square blocks 310, and multiple square blocks 310 are disposed on the inner wall of the plastic frame bottom mold 100 and located between the energy storage battery bodies 200. A pin is fixed at the bottom end of the inner wall of the plastic frame bottom mold 100 at a position corresponding to the battery-side fixing mechanism 300. The bottom end of the battery-side fixing mechanism 300 is inserted into the outer wall of the pin through a pin hole. The fixed pin and the pin hole are for convenient fixing of the battery-side fixing mechanism 300 to the bottom end of the inner wall of the plastic frame bottom mold 100. Both ends of the outer wall of the square block 310 are provided with arc-shaped clamping blocks 321. The side walls of the arc-shaped clamping blocks 321 abut against the side ends of the outer wall of the energy storage battery body 200. A sliding rod 320 is fixed on the opposite side of each of the two arc-shaped clamping blocks 321. The outer walls of the square block 310 are slidably connected to the outer walls of the sliding rods 320 by opening sliding grooves. Wedge-shaped inserts 330 are inserted at the top of the outer wall of the square block 310 and between the sliding rods 320. The insertion end of the sliding rod 320 is connected to the outer wall of the wedge-shaped insert 330. The sliding rod 320 is inclined at the contact end with the wedge-shaped insert 330 and matches the outer wall side of the wedge-shaped insert 330. The wedge-shaped insert 330 can be inserted into the square block 310, thereby squeezing the sliding rod 320 to both sides, so that the arc-shaped clamp 321 can press against both sides of the outer wall of the energy storage battery body 200. In this way, the energy storage battery body 200 can be pressed and fixed from both sides of the outer wall of the energy storage battery body 200.

Then, personnel can remove the square block 310 and connect the pin hole opened at the bottom of the square block 310 with the pin opened at the bottom of the inner wall of the plastic frame bottom mold 100. After completion, personnel can remove the wedge-shaped insert 33. 0, and insert the wedge-shaped insert 330 into the square block 310 from the top. The structure of the wedge-shaped insert 330 will cause the slide bar 320 and the arc-shaped clamp 321 to move outward, so that the arc-shaped clamp 321 can press against the top of the outer wall of the energy storage battery body 200. At the same time, the personnel also need to take out the side clamping block 210 and place it on both sides of the inner wall of the plastic frame bottom mold 100 to press against the outermost side of the energy storage battery body 200, so as to clamp and fix the energy storage battery body 200 from both sides.

Then, the operator can take out the bolts to tighten and fix the side connecting block 400. After the plastic frame top cover 500 is fixed, the upper arc-shaped bracket 530 can limit and fix the energy storage battery body 200 from the top. The heat dissipation groove 510 can improve the heat dissipation of the energy storage battery body 200 during use.
