In the prior art, the traditional lithium battery group usually adopts the fixed structure design, uses a large number of screws, fasteners and adhesives to ensure the stability and safety of the battery pack, and this design also makes the process become extremely cumbersome when needing to disassemble or repair, since the fixing mode of the battery pack is various, often needs specific tools to disassemble, such as special specification screwdriver, wrench etc. This not only increases the complexity of operation, also puts forward higher requirement to the professional skill of maintenance personnel, and lithium battery is particularly sensitive, if improper operation during disassembly, can cause battery damage, short circuit even thermal runaway. Therefore, the disassembly process needs extremely careful, this undoubtedly increases the operation time and difficulty, in view of such problems, the utility model discloses a novel fixing device when lightweight lithium battery needs to be installed, it is connected with the fixed pin through the connecting plate, the fixed pin is inserted into the fixed sleeve, and the supporting plate and the supporting spring provide support and pressure, ensure that its position is stable, at the same time, the user operates the pull button, pulls the pull button and drives the lock disc to move backward, waits for the fixed pin to slide into the fixed sleeve, at the same time, the pull button is loosened, the lock disc is pushed forward by the push spring, when the fixed pin is lowered to the lock groove and the pull button is aligned, the push spring pushes the lock disc into the lock groove, realizes locking, when needing to disassemble the battery, the user operates the pull button again, makes the lock disc and the lock groove of the fixed pin separate, thereby releasing the fixed pin, allows the battery to be removed, thereby realizing providing a quick, reliable and reusable way to fix and disassemble lightweight lithium battery, and ensuring the stability of the battery during equipment operation.

[0006] Preferably, the integrated base has heat dissipation grooves on its surface. In the prior art, the design of integrated bases often focuses on structural compactness and protection. While such highly enclosed integrated bases can effectively protect internal components from external influences, they also introduce heat dissipation problems. These problems are particularly prominent in battery technology applications, as batteries generate heat during charging and discharging. If this heat cannot be effectively dissipated from the system in a timely manner, it will lead to a series of performance and safety issues. To address these problems, this invention provides a larger heat exchange area by increasing the surface area of ​​the integrated base through heat dissipation grooves. This increased surface area allows more heat to be transferred from the interior of the integrated base to the external environment through conduction and convection. The design of the heat dissipation grooves typically takes aerodynamic principles into account, and their shape and arrangement promote airflow. When the device is running, internal and external air can circulate through these grooves, forming an effective heat dissipation path, thereby carrying away accumulated heat and preventing damage to the lithium battery.

[0007] Preferably, the integrated base has a square groove on its surface, and a pad is fixed to the inner wall of the square groove. The pad, as a buffer material, is located between the inner wall of the square groove and the battery. It can absorb and disperse the impact force generated during normal use or accidental collision, which reduces the mechanical stress directly acting on the battery, thereby protecting the battery from damage.

[0008] Preferably, the surface of the pull button is covered with a rubber sleeve, the surface of which usually has a certain degree of stickiness and friction. This effectively increases the frictional resistance when gripping the movable ring, thereby improving the stability of the grip.

[0009] Preferably, the bottom of the integrated base is provided with anti-slip grooves. The anti-slip grooves work by increasing the surface roughness of the bottom of the integrated base, providing more friction, thereby reducing the slippage of the equipment on the contact surface and improving the stability of the equipment.

[0010] Preferably, the surface of the pad has honeycomb grooves. The design of the honeycomb grooves allows the pad to provide more functional space without increasing the volume, so that every part of the material can be used more efficiently.

[0011] Preferably, the width of the square slot is greater than the width of the lightweight lithium battery. Designing the square slot wider than the lithium battery ensures that the lithium battery can be easily inserted into the base. This design provides sufficient space, making the battery installation and removal process easier and reducing potential damage to the battery during assembly or maintenance.

[0012] Beneficial effects

[0013] 1、In the prior art, the traditional lithium battery group usually adopts a fixed structure design, a large number of screws, fasteners and adhesives are used to ensure the stability and safety of the battery group, and such a design also makes the process extremely cumbersome when disassembly or maintenance is needed, since the fixed mode of the battery group is various, special tools such as screwdrivers and wrenches are often needed to disassemble. This not only increases the complexity of the operation, but also puts higher requirements on the professional skills of the maintenance personnel. Lithium batteries are particularly sensitive, and improper operation during disassembly may cause battery damage, short circuit or even thermal runaway. Therefore, the disassembly process needs to be extremely careful, which undoubtedly increases the operation time and difficulty. In view of such problems, the utility model adopts a new type of fixing device, when the lightweight lithium battery needs to be installed, it is connected with the fixing pin through the connecting plate, the fixing pin is inserted into the fixing sleeve, and the support plate and the support spring provide support and pressure, so as to ensure the stability of the position, at the same time, the user operates the pull button, pulls the pull button to drive the lock disc to move backward, waits for the fixing pin to slide into the inside of the fixing sleeve, and at the same time, the pull button is loosened, the lock disc is pushed forward by the push spring, when the fixing pin is lowered to the lock groove and the pull button is aligned, the push spring pushes the lock disc into the lock groove, and locking is realized. When the battery needs to be disassembled, the user operates the pull button again, so that the lock groove of the lock disc and the fixing pin are separated, so as to release the fixing pin and allow the battery to be removed, thereby a quick, reliable and reusable way is provided to fix and disassemble the lightweight lithium battery, and the stability of the battery during equipment operation is ensured.

[0014] 2、In the prior art, the design of the integrated base usually focuses on the compactness and protection of the structure, and such an integrated base with high covering property can effectively protect the internal components from external influences, but at the same time, it also brings some heat dissipation problems. These problems are particularly prominent in battery technology applications, because the battery generates heat during charging and discharging, and if the heat cannot be effectively discharged from the system in time, a series of performance and safety problems will be caused. In view of such problems, the utility model increases the surface area of the integrated base through the heat dissipation groove to provide more heat exchange area. Such an increased surface area allows more heat to be transferred from the inside of the integrated base to the outside environment through conduction and convection, and the design of the heat dissipation groove usually considers the principle of aerodynamics, and the shape and arrangement thereof can promote air flow. When the equipment is running, the internal and external air can flow through these grooves to form an effective heat dissipation path, thereby taking away the accumulated heat, so as to avoid damage to the lithium battery.
