Description
Technical Field
[0001] This utility model relates to the field of battery pack technology, specifically a removable battery pack. Background Technology
[0002] As environmental issues become increasingly prominent, lead-acid batteries are gradually being replaced by lithium-ion batteries. Lithium-ion batteries require large-scale series and parallel assembly during use, necessitating management systems to manage a large number of individual cells. Currently, a common approach involves parallel welding of numerous individual cells followed by series welding, resulting in all cells being welded together. This method is inconvenient for production operations; if even one cell fails during use, the entire battery pack must be scrapped. While this invention's modular batteries still require welding, the standardized modules facilitate large-scale production. If a single cell fails during use, only the battery module needs to be replaced, eliminating the need to replace the entire battery pack. Furthermore, this plug-and-play, quick-assembly lithium-ion battery pack is remarkably easy to maintain. In practical use, with minimal training, dealers can easily replace the batteries themselves, significantly reducing after-sales costs.
[0003] In existing pull-out battery packs, the insertion rods of the disassembly structure cannot be stably inserted into the battery pack during the pull-out and disassembly process, which affects the operation of the battery pack and thus the stability of the disassembly process. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a removable battery pack. By setting heat dissipation holes, the plug of the disassembly structure can be stably inserted into the heat dissipation holes to remove and disassemble the battery pack during the removal and disassembly process. This ensures the stability of the battery pack during removal and disassembly, avoids damage to the battery pack, and can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable battery pack, comprising a battery pack body, an upper limit groove on the upper side of the battery pack body, a lower limit groove on the lower side of the battery pack body, limit wedges at the four corners of one end face of the battery pack body, a limit locking block integrally formed on the side of the limit wedges facing the battery pack body, threaded rods rotatably connected to the opposite sides of the upper and lower limit wedges, a fixing plate fixedly connected to the outer shell of the battery pack body passing through the threaded rods, a limit locking groove on the side of the battery pack body corresponding to the installation of the limit wedges, a bidirectional thrust bearing at the contact position between the threaded rods and the limit wedges, a handle at the center of the side of the battery pack body with the limit locking grooves, and two heat dissipation holes inside the battery pack body above the handle.
[0006] Furthermore, two wiring blocks are provided on the side of the battery pack away from the handle, and protective metal plates are fixed to the inner sides of both the upper limit groove and the lower limit groove.
[0007] Furthermore, the limiting wedge is connected to the battery pack body through the limiting slot and the limiting block, and the threaded rod is connected to the inner ring side of the bidirectional thrust bearing by screws.
[0008] Furthermore, the threaded rod is threadedly connected to the fixing plate, and the handle is rotatably connected to the battery pack shell.
[0009] Furthermore, the length of the heat dissipation vent is two-thirds of the length of the battery pack, the heat dissipation vent has a rectangular square tube structure, and the heat dissipation vent is made of copper.
[0010] Furthermore, the wiring block is fixedly connected to the terminal block inside the battery pack, and the wiring protrusion inside the wiring block is set downwards.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the provision of heat dissipation holes, allows the insertion rod of the disassembly structure to be stably inserted into the heat dissipation holes during the insertion and removal of the battery pack, thereby enabling stable transport of the battery pack. When the battery pack is not being inserted or removed, the heat dissipation holes facilitate heat dissipation of the battery pack, and the insertion of the insertion rod into the heat dissipation holes ensures the stability of the battery pack during insertion and removal, preventing damage to the battery pack.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This embodiment provides a technical solution: a retractable battery pack, including a battery pack body 1. The upper side of the battery pack body 1 is provided with an upper limit groove 2, and the lower side of the battery pack body 1 is provided with a lower limit groove 3. Limit wedges 5 are provided at the four corners of one end face of the battery pack body 1. A limit locking block 8 is integrally formed on the side of the limit wedges 5 facing the battery pack body 1. Threaded rods 7 are rotatably connected to the opposite sides of the upper and lower limit wedges 5. A fixing plate 6, which is fixedly connected to the outer shell of the battery pack body 1, passes through the threaded rods 7. A limit locking groove 10 is opened on the side of the battery pack body 1 corresponding to the installation of the limit wedges 5. A bidirectional thrust bearing 9 is provided at the contact position between the threaded rod 7 and the limit wedges 5. A handle 11 is provided at the center of the side of the battery pack body 1 with the limit locking groove 10. Two heat dissipation holes 12 are opened in the battery pack body 1 above the handle 11.
[0020] like Figure 1-4 As shown, during use, the insertion rod of the disassembly mechanism is inserted into the heat dissipation hole 12, thereby allowing the disassembly mechanism to lift the battery pack 1 and send it into the battery body fixing frame. This allows the end of the battery pack 1 with the wiring block 4 to connect with the wiring structure on the battery fixing frame, thereby allowing the power of the battery pack 1 to be supplied to the electrical equipment. The battery pack 1 and the fixing frame are limited by the upper limit groove and the lower limit groove 3. After installation, the threaded rod 7 is rotated so that the limit wedge 5 can be locked into the wedge slot, thereby making the battery pack 1 stably locked and fixed on the fixing frame, ensuring the fixing effect of the battery pack 1.
[0021] Two wiring blocks 4 are provided on the side of the battery pack 1 away from the handle 11. Protective metal plates are fixed on the inner sides of the upper limit groove 2 and the lower limit groove 3. The protective metal plates in the upper limit groove 2 and the lower limit groove 3 can ensure the stability of the battery pack 1 during frequent insertion and removal, and prevent damage to the outer shell of the battery pack 1.
[0022] The limiting wedge 5 is connected to the battery pack body 1 through the limiting slot 10 and the limiting block 8. The threaded rod 7 is connected to the inner ring side of the bidirectional thrust bearing 9 by screws. The bidirectional thrust bearing 9 can make the threaded rod 7 rotate, and the pushing and pulling force when the threaded rod 7 rotates will drive the limiting wedge 5 to move along the limiting slot 10.
[0023] The threaded rod 7 is connected to the fixing plate 6 by a thread. The rotation of the threaded rod 7 can push and pull the limiting wedge 5, so that the limiting wedge 5 can be stably locked into the wedge limiting slot, ensuring that the battery pack 1 is effectively limited and fixed, and avoiding shaking. The handle 11 is rotatably connected to the outer shell of the battery pack 1.
[0024] The length of the heat dissipation socket 12 is two-thirds of the length of the battery pack 1. The heat dissipation socket 12 is a rectangular square tube structure and is made of copper. The length of the heat dissipation socket 12 can ensure that the plug of the disassembly structure can stably insert the battery pack 1, thereby ensuring that the disassembly process of the battery pack 1 is stable and smooth.
[0025] The terminal block 4 is fixedly connected to the terminal post inside the battery pack body 1, and the terminal protrusion inside the terminal block 4 is set downwards.
[0026] The working principle of the removable battery pack provided by this utility model is as follows: Figures 1-4 As shown, during use, the insertion rod of the disassembly mechanism is inserted into the heat dissipation hole 12, thereby allowing the disassembly mechanism to lift the battery pack 1 and send it into the battery body fixing frame. This allows the end of the battery pack 1 with the wiring block 4 to connect with the wiring structure on the battery fixing frame, thereby allowing the power of the battery pack 1 to be supplied to the electrical equipment. The battery pack 1 and the fixing frame are limited by the upper limit groove and the lower limit groove 3. After installation, the threaded rod 7 is rotated so that the limit wedge 5 can be locked into the wedge slot, thereby making the battery pack 1 stably locked and fixed on the fixing frame, ensuring the fixing effect of the battery pack 1.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
