Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to a battery pack with an auxiliary disassembly structure. Background Art

[0002] The water-cooling plate is integrated into the box or placed separately between the battery module and the inner surface of the lower box. To improve the cooling effect, a layer of thermal conductive glue / thermal conductive pad is set between the battery module and the water-cooling plate to transfer the heat of the battery cells in the battery module to the water-cooling plate through the thermal conductive glue / thermal conductive pad, and the heat is taken away by the water-cooling plate. The thermal conductive glue / thermal conductive pad usually has a certain bonding strength, and it is difficult to remove the battery module when the battery module needs to be disassembled.

[0003] The Chinese invention patent application with prior art application number 202310782358.3 and titled "Positioning Auxiliary Device, Battery Module, and Battery Pack Electrical Device" discloses: a card slot is provided on the fixing bolt, and an elastically deformable card protrusion is provided on the positioning auxiliary disassembly device. When the battery module is fixed, the fixing bolt passes through the bolt through hole of the battery module and abuts against the positioning auxiliary disassembly device. Under the action of external force, the fixing bolt squeezes the positioning auxiliary disassembly device, and the guide card connection portion of the positioning auxiliary disassembly device is squeezed and opened outward from the center line, and the fixing bolt passes through the positioning auxiliary disassembly device and is screwed to the bottom plate; when the battery module needs to be disassembled, the fixing bolt is loosened, and the positioning auxiliary disassembly device moves upward until the card protrusion is coupled with the card slot and stuck. When it is urgent to loosen the bolt, the positioning auxiliary disassembly device pushes the battery module upward until the battery module is separated from the thermal conductive glue / thermal conductive pad of the box.

[0004] The structure of the prior art has the following problems:

[0005] 1. The fixing bolt needs to be provided with an annular groove, which partially reduces the cross-sectional area of ​​the bolt and reduces the mechanical strength of the fixing bolt;

[0006] 2. The annular grooves for fixing bolts need to be customized in batches, which increases the cost;

[0007] 3. The positioning auxiliary disassembly device is made of plastic. The fixing bolt squeezes the positioning auxiliary disassembly device under the action of external force, so that the guide clamping part of the positioning auxiliary disassembly device is squeezed outward from the center line. During the process, the thread of the fixing bolt contacts the guide clamping part, which can easily cause the guide clamping part to wear and fail to couple with the card slot;

[0008] 4. The positioning auxiliary disassembly device has an interference fit with the sinking hole on the base plate, making installation inconvenient.

[0009] Therefore, based on the above technical problems, technicians in this field urgently need to develop a battery pack with an auxiliary disassembly structure. Utility Model Content
