Description

Technical Field

[0002] The battery pack subframe assembly is a component in electric vehicles or hybrid vehicles. Generally speaking, the subframe assembly plays the role of supporting and fixing the battery pack. It is generally made of metal materials and has a certain strength and rigidity. It can withstand the weight of the battery pack and various forces and vibrations generated during vehicle driving.

[0003] The battery pack sub-beam assembly mainly consists of two parts: a mounting frame and a sealing cover plate on the top. A fixing component is provided inside the mounting frame, and multiple groups of battery pack bodies are fixed through the fixing components inside the mounting frame to achieve the installation and fixation of the battery pack bodies and the mounting frame. The mounting frame is then sealed through the sealing cover plate on the top. However, in actual use, the heat generated by multiple groups of adjacently installed battery packs is difficult to dissipate from the inside of the mounting frame, thereby reducing the service life of the battery pack. At the same time, during long-term use, damaged battery packs are not convenient to be disassembled and replaced separately, thereby increasing the trouble of replacing damaged battery packs. In view of the shortcomings of the existing technology, we propose a battery pack sub-beam assembly to solve the above problems. Utility Model Content

[0025] A plurality of limiting frames 401 are provided inside the mounting frame 4, and the battery pack main body 3 is limitedly installed inside the limiting frame 401. A plurality of heat dissipation channels are formed between the limiting frame 401, the mounting frame 4 and the mounting frame 1. A plurality of movable cover plates 301 are provided on the top of the upper sealing cover plate 2. The movable cover plates 301 are located on the top of the battery pack main body 3. The movable cover plates 301 and the upper sealing cover plate 2 are detachable. When installing a plurality of battery pack main bodies 3 inside the mounting frame 1, the battery pack main bodies 3 are picked up respectively so that the battery pack main bodies 3 are limitedly installed inside the limiting frame 401. Then, the upper sealing cover plate 2 is picked up so that the rectangular grooves at the bottom of the upper sealing cover plate 2 are aligned with the top of the battery pack main body 3, and are respectively installed on the top of the battery pack main body 3. Then, the installed mounting frame 1 and the upper sealing cover plate 2 are fixed by the first fixing bolts 201.

[0026] A limiting frame 6 is set on the top of the multi-group battery pack main body 3. It should be noted that the top of the limiting frame 401 is lower than the top of the battery pack main body 3. The battery pack main body 3 is limited and installed inside the limiting frame 401. At the same time, the installed movable cover 301 and the limiting frame 6 press the battery pack main body 3 inside the limiting frame 401 to complete the installation and fixation of the battery pack main body 3, avoiding displacement or shaking of the battery pack main body 3 during use, ensuring that the battery pack is firmly installed and will not be displaced due to vibration or bumps during vehicle driving, and improving the strength of the installation of the multi-group battery pack main body 3 and the battery pack assembly. The limiting frame 6 limits the top of the battery pack main body 3, and the limiting frame 6 is fixedly installed at the bottom of the movable cover 301, reinforcing ribs 5 are fixedly distributed on the inner peripheral wall and inner bottom of the mounting frame 1, and one end of the reinforcing rib 5 is fixedly connected to the outer peripheral wall and outer bottom of the mounting frame 4 respectively.
