Description

Technical Field

[0001] The utility model relates to a battery disassembly device, specifically a portable and detachable power battery disassembly device for new energy vehicles, belonging to the technical field of new energy vehicle maintenance. Background Technique

[0002] With the global emphasis on environmental protection and the growing demand for sustainable energy, new energy vehicles have developed rapidly due to their low emissions and high energy efficiency. As the core component, the performance and technical level of the assembled power battery directly determine the key indicators of new energy vehicles such as driving range, charging time, safety, and cost.

[0003] With the progress of technology, the energy density of power batteries has gradually increased, and the driving range has been significantly improved. However, it also brings more complex maintenance problems. For example, the batteries of pure electric vehicles are usually large in volume and mass. On the one hand, some users prefer fast charging to save time during vehicle use, in which case the consistency of single cells will become worse and the corresponding equalization maintenance times will increase. On the other hand, due to factors such as the use environment conditions, the failure rate of power batteries is relatively high. However, components such as contactors and BMS are all installed inside the power battery, so the disassembly and assembly of the power battery and the opening inspection are required during maintenance. Therefore, the disassembly of the power battery is a high-frequency item in new energy vehicle maintenance operations. However, due to its special installation, a special disassembly device is needed.

[0004] Currently, most of the existing new energy power battery disassembly devices are integrated pneumatic or hydraulic lifting devices, which are large and bulky and cannot be carried by conventional-sized passenger cars during out-of-town rescue and maintenance. Moreover, they require an external power supply or gas source, and the operation is relatively inconvenient. Therefore, a portable and detachable power battery disassembly device for new energy vehicles is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a portable and detachable power battery disassembly device for new energy vehicles to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the embodiment of the utility model is realized as follows: A portable and detachable disassembly device for a power battery of a new energy vehicle, including four support columns. Four L-shaped fixing plates are fixedly connected to the outer side walls of the four support columns. Two upper cross beams are provided at the tops of the four support columns. Two support arms are symmetrically and slidably connected to the inner side walls of the two upper cross beams. Four insulating support seats are provided above the support arms. Insulating threaded sleeves are threadedly connected to the bottoms of the outer side walls of the four insulating support seats. The outer side walls of the insulating threaded sleeves are fixedly connected to the inner side walls of the support arms. The two ends of the two upper cross beams are respectively fixedly connected to the four L-shaped fixing plates by bolts.

[0007] Further preferably, guide grooves are provided on one side of each of the support arms, and blind holes are provided on the other side of each of the support arms. The outer side walls of the insulating threaded sleeves are fixedly connected to the inner side walls of the blind holes.

Two upper connecting rods are symmetrically provided at the tops of the adjacent sides of the four support columns. The two ends of the two upper connecting rods are respectively fixedly connected to another four L-shaped fixing plates by bolts.

[0009] Further preferably, four connecting seats are fixedly connected to the bottoms of the four support columns, and four universal wheels are installed at the bottoms of the four connecting seats;

[0010] Among them, two of the universal wheels have a braking function, and the other two universal wheels do not have a braking function.

[0011] Further preferably, both the two lower cross beams and the lower connecting rods are located 3-7 cm above the connecting seats, and both the two upper connecting rods are located 8-12 cm below the two upper cross beams.

[0012] Further preferably, two lower pull plates are fixedly connected between the two lower connecting rods by bolts, and the two lower pull plates are arranged in a staggered up and down manner.

[0013] Further preferably, fixing bolts are fixedly connected to one side of each of the four support columns, and two side pull plates are fixedly connected between the four fixing bolts, and the two side pull plates are arranged in a staggered space.
