[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the utility model: a combined lithium-ion battery, comprising a fixing frame 1, a card slot 4 is provided inside the fixing frame 1, a frame 2 is slidably connected inside the fixing frame 1, a lithium battery 3 is arranged inside the frame 2, a connecting block 5 is fixedly connected to the bottom of the frame 2, an outer wall of the connecting block 5 is slidably connected to the inside of the card slot 4, a limiting column 7 is fixedly connected inside the connecting block 5, a connecting groove 6 is provided inside the connecting block 5, an outer wall of the limiting column 7 is symmetrically provided with a sliding connection limiting ring 8, an outer wall of the limiting ring 8 is provided with a limiting assembly, an outer wall of the limiting ring 8 is rotatably connected with a connecting rod 10, one end of the connecting rod 10 is rotatably connected with a card block 11, an outer wall of the card block 11 is embedded in the inside of the card slot 4, an outer wall of the limiting column 7 is sleeved with a spring 12, and the limiting assembly comprises a limiting block 9, one side of the limiting block 9 is fixedly connected to the outer wall of the limiting ring 8, and the outer wall of the limiting block 9 is slidably connected to the inside of the connecting groove 6;

[0031] Specifically, when the lithium battery 3 needs to be installed, we first place the lithium battery 3 inside the frame 2. The frame 2 is very cleverly designed. It can slide into the card slot 4 for limiting through the connecting block 5 at the bottom. After this process is completed, the card block 11 inside the connecting block 5 will naturally embed into the card slot 4 for locking. This ensures that the lithium battery 3 is firmly fixed inside the fixing frame 1. In order to further enhance the stability of the lithium battery 3, the card slot 4 is limited on the outer wall of the limiting column 7 by the limiting ring 8 on the connecting rod 10, and the tension of the spring 12 will provide support for the limiting ring 8, so that it is not easy to slide out. This design takes into account various possible usage scenarios, so that the lithium battery 3 always remains stable. It is worth mentioning that the limiting ring 8 is slidably limited inside the connecting groove 6 by the limiting block 9, so as to prevent the limiting ring 8 from rotating and dislocating around the limiting column 7. This meticulous design takes into account various possible usage scenarios, so that the lithium battery 3 always remains stable.

[0032] Reference Figure 3 A cooling box 13 is provided on one side of the fixing frame 1, a top cover 14 is provided on the top of the cooling box 13, a water pump 18 is fixedly connected to one side of the cooling box 13, an input end of the water pump 18 is fixedly connected to one side of the cooling box 13, a coil 17 is fixedly connected to the output end of the water pump 18, one end of the coil 17 is fixedly connected to the inside of the cooling box 13, an outer wall of the coil 17 is embedded in the fixing frame 1, a refrigeration plate 15 is fixedly connected to the inside of the cooling box 13, a heat conducting plate 16 is fixedly connected to one side of the refrigeration plate 15, one end of the spring 12 is fixedly connected to one end of the limit ring 8, and the other end of the spring 12 is fixedly connected to the inside of the connecting block 5;

[0033] Specifically, in the cooling of lithium batteries, heat dissipation is a crucial link, and the refrigeration plate 15 plays a core role. It cools down the coolant inside the cooling box 13 to ensure that its temperature is maintained in an appropriate range. In order to achieve this goal, the refrigeration plate 15 is in full contact with the coolant through the thermal conductive plate 16 to ensure that heat can be quickly and evenly transferred to the coolant. Next, the water pump 18 begins to play its role. The input end of the water pump 18 draws coolant from the inside of the cooling box 13, and then pumps it into the coil 17 through the output end of the water pump 18. The coil 17 is a carefully designed structure that can effectively take away the heat generated by the lithium battery 3. Inside the coil 17, the heat exchange efficiency between the coolant and the lithium battery 3 is extremely high, and the heat can be quickly extracted from the lithium battery 3. After completing the heat exchange, the coolant flows back to the inside of the cooling box 13 through the coil 17 again, starting a new round of circulation. This cycle continues to ensure that the lithium battery 3 is always kept within a suitable temperature range, thereby ensuring its stable and efficient operation.

[0034] Working principle: When using a combined lithium-ion battery, first install the lithium battery 3, fix the lithium battery 3 inside the frame 2, then slide the frame 2 into the card slot 4 through the bottom connecting block 5 for limiting, then make the card block 11 inside the connecting block 5 embed into the card slot 4 for locking, so that the lithium battery 3 is fixed inside the fixing frame 1, the card slot 4 is limited on the outer wall of the limiting column 7 by the limiting ring 8 on the connecting rod 10, and the limiting ring 8 is supported by the tension of the spring 12, and then the connecting rod 10 on the limiting ring 8 drives the card block 11 to extend and fit into the card slot 4 without It is easy to slide out, and the limit ring 8 is slidably limited inside the connecting groove 6 by the limit block 9 to prevent the limit ring 8 from rotating and dislocating around the limit column 7. When dissipating heat, the refrigeration plate 15 cools the coolant inside the cooling box 13. The refrigeration plate 15 fully contacts the coolant with the temperature through the heat conduction plate 16 to make the coolant fully civilized. The input end of the water pump 18 draws the coolant inside the cooling box 13 and pumps it into the coil 17 through the output end of the water pump 18. The heat generated by the lithium battery 3 is taken away by the coil 17, and the coolant is returned to the cooling box 13 through the coil 17 for circulation.
