Description

Technical Field

[0001] This utility model relates to the field of lithium battery assembly technology, specifically to a polymer lithium battery that can be used in combination. Background Technology

[0002] Polymer lithium batteries are lithium-ion batteries that use polymer materials as electrolytes or part of the structure. Their core features include high energy density, miniaturization, lightweight, and high safety.

[0003] However, existing polymer lithium batteries are generally bundled together and then wrapped with an aluminum-plastic composite film during assembly. This makes it inconvenient to install and disassemble the polymer lithium batteries, reducing the efficiency of installation and disassembly. To address the above problems, the inventors propose a polymer lithium battery that can be used in combination to solve the above problems. Utility Model Content

[0004] To address the inconvenience of installing and disassembling polymer lithium batteries, the purpose of this invention is to provide a polymer lithium battery that can be used in combination.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: A polymer lithium battery that can be used in combination includes a protective frame and a lithium battery body. The lithium battery body is installed inside the protective frame, and a heat dissipation groove is provided inside the protective frame. A mounting frame and a splicing plate are respectively installed on both sides of the protective frame. The splicing plate is slidably inserted into the mounting frame. A threaded tube is fixedly installed inside the mounting frame, and a threaded rod is threaded through the threaded tube. An L-shaped plate is slidably installed inside the mounting frame, and the threaded rod is rotatably connected to the top surface of the L-shaped plate. An insertion rod is fixedly installed on the bottom surface of the L-shaped plate, and the insertion rod is slidably inserted into the splicing plate. A slot is provided inside the splicing plate, and the insertion rod is slidably inserted into the slot. A limiting groove is provided inside the mounting frame, and a limiting block is fixedly installed on one side of the L-shaped plate. The limiting block is slidably installed in the limiting groove. First, a first positioning rod on one side of the mounting frame and a second positioning rod on one side of the splicing plate are inserted into the groove inside the protective frame. Then, a moving rod is inserted into the first positioning rod on the mounting frame. The first and second positioning rods facilitate the installation of the mounting frame and splicing plate on both sides of the protective frame. Then, the threaded rods on both sides of one of the protective frames are rotated, causing the threaded rods to rotate inside the threaded tubes and drive the L-shaped plate to rise and slide inside the mounting frame. At the same time, the limiting block slides inside the limiting groove. Next, the splicing plate on one side of the other protective frame is slid into the corresponding mounting frame, so that the splicing plate coincides with the mounting frame. At this time, the slot opened in the splicing plate corresponds to the insertion rod. Then, the threaded rod is rotated, so that the L-shaped plate fits against the top surface of the splicing plate and the insertion rod is inserted into the slot, thereby enabling the splicing plate to be installed in the mounting frame. This allows the two protective frames to be combined for the use of the lithium battery body without the need for aluminum-plastic composite film wrapping, which facilitates assembly and installation and improves the efficiency of installation and disassembly. At the same time, there is a gap between the two protective frames after installation, so that the heat generated by the lithium battery body can be discharged from the heat dissipation groove, avoiding overheating and safety hazards.

[0006] Next, by pulling the lever, the moving rod drives the moving ring to slide in the fixed groove. At the same time, the spring is squeezed, causing the moving rod to disengage from the first and second positioning rods. This makes it easier to disassemble and install the mounting frame and splicing plate. When the bottom or top protective frame does not need to use the mounting frame and splicing plate, it can be easily disassembled, thus saving installation space and not creating more usable space.

[0007] Preferably, the protective frame has a groove, a first positioning rod is fixedly provided on one side of the mounting frame, and a second positioning rod is fixedly provided on one side of the splicing plate. The first and second positioning rods are slidably inserted into the groove, and positioning slots are provided in the first and second positioning rods. The moving rod is slidably inserted into the positioning slot.

[0008] Preferably, a lever is slidably provided inside the protective frame, and a movable rod is fixedly provided on one side of the lever. The movable rod is slidably inserted into the protective frame and is slidably inserted into the first positioning rod and the second positioning rod. A movable ring is fixedly sleeved on the outer surface of the movable rod. The movable ring is slidably disposed inside the lever. A fixing groove is provided inside the protective frame. The movable ring is slidably disposed in the fixing groove, and a spring is fixedly connected between the fixing groove and the movable ring.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The splicing plate slides into the corresponding mounting frame, so that the splicing plate coincides with the mounting frame. Then, the L-shaped plate is attached to the top surface of the splicing plate, and the plug is inserted into the slot, so that the lithium battery body can be combined and used without the need to use aluminum-plastic composite film to wrap it, which facilitates the assembly and installation and improves the efficiency of installation and disassembly.

[0011] 2. By moving the rod away from the first and second positioning rods, the mounting frame and splicing plate can be easily disassembled and installed. When the bottom or top protective frame does not need to use the mounting frame and splicing plate, it can be easily disassembled, thereby saving installation space and not creating more usable space.

[0019] 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.

[0020] Example: Figure 1-5As shown, this utility model provides a polymer lithium battery that can be used in combination, including a protective frame 1 and a lithium battery body 11. The lithium battery body 11 is installed inside the protective frame 1. A heat dissipation groove 101 is provided inside the protective frame 1. Mounting frames 2 and splicing plates 27 are respectively installed on both sides of the protective frame 1. The splicing plates 27 are slidably inserted into the mounting frames 2. A threaded tube 26 is fixedly installed inside the mounting frames 2. A threaded rod 22 is threaded through the threaded tube 26. An L-shaped plate 23 is slidably installed inside the mounting frames 2. The threaded rod 22 is rotatably connected to the top surface of the L-shaped plate 23. A plug rod 24 is fixedly installed on the bottom surface of the L-shaped plate 23. The plug rod 24 is slidably inserted into the splicing plate 27. A slot 271 is provided in the splicing plate 27, and the plug rod 24 is slidably inserted into the slot 271. A limit groove 201 is provided in the mounting frame 2. A limit block 25 is fixedly installed on one side of the L-shaped plate 23, and the limit block 25 is slidably installed in the limit groove 201. By rotating the threaded rods 22 on both sides of one of the protective frames 1, the threaded rod... The threaded rod 22 rotates inside the threaded tube 26, causing the L-shaped plate 23 to rise and slide inside the mounting frame 2. At the same time, it causes the limiting block 25 to slide inside the limiting groove 201. Then, the splicing plate 27 on one side of the other protective frame 1 is slid into the corresponding mounting frame 2, so that the splicing plate 27 coincides with the mounting frame 2. At this time, the slot 271 opened in the splicing plate 27 corresponds to the insertion rod 24. Then, the threaded rod 22 is rotated, so that the L-shaped plate 23 fits against the top surface of the splicing plate 27, and the insertion rod 24 is inserted into the slot 271. Thus, the splicing plate 27 can be installed in the mounting frame 2, and the two protective frames 1 can be combined for the use of the lithium battery body 11. There is no need to use aluminum-plastic composite film to wrap it, which facilitates the assembly and installation, improves the efficiency of installation and disassembly. At the same time, there is a gap between the two protective frames 1 after installation, so that the heat generated by the lithium battery body 11 can be discharged from the heat dissipation groove 101, avoiding excessive temperature and safety hazards.

[0021] The protective frame 1 has a groove 102. A first positioning rod 21 is fixedly installed on one side of the mounting frame 2, and a second positioning rod 28 is fixedly installed on one side of the splicing plate 27. The first positioning rod 21 and the second positioning rod 28 are slidably inserted into the groove 102. A positioning groove 211 is opened in the first positioning rod 21 and the second positioning rod 28, and the moving rod 31 is slidably inserted into the positioning groove 211.

[0022] By adopting the above technical solution, the first positioning rod 21 on one side of the mounting frame 2 and the second positioning rod 28 on the side of the splicing plate 27 are inserted into the groove 102 in the protective frame 1, and then the moving rod 31 is inserted into the first positioning rod 21 and the second positioning rod 28, which facilitates the installation of the mounting frame 2 and the splicing plate 27 on both sides of the protective frame 1.

[0023] A lever 3 is slidably provided inside the protective frame 1. A moving rod 31 is fixedly provided on one side of the lever 3. The moving rod 31 is slidably inserted into the protective frame 1 and is slidably inserted into the first positioning rod 21 and the second positioning rod 28. A moving ring 32 is fixedly sleeved on the outer surface of the moving rod 31. The moving ring 32 is slidably provided in the lever 3. A fixing groove 103 is provided inside the protective frame 1. The moving ring 32 is slidably provided in the fixing groove 103. A spring 33 is fixedly connected between the fixing groove 103 and the moving ring 32.

[0024] By adopting the above technical solution, by pulling the lever 3, the moving rod 31 drives the moving ring 32 to slide in the fixed groove 103. At the same time, the spring 33 is squeezed, causing the moving rod 31 to disengage from the first positioning rod 21 and the second positioning rod 28. This makes it easier to disassemble and install the mounting frame 2 and the splicing plate 27. When the bottom or top protective frame 1 does not need to use the mounting frame 2 and the splicing plate 27, it is easy to disassemble it, thereby saving installation space and not creating more usable space.

[0025] Working principle: First, insert the first positioning rod 21 on one side of the mounting frame 2 and the second positioning rod 28 on one side of the splicing plate 27 into the groove 102 inside the protective frame 1. Then, insert the moving rod 31 into the first positioning rod 21 and the second positioning rod 28, which facilitates the installation of the mounting frame 2 and the splicing plate 27 on both sides of the protective frame 1. Then, rotate the threaded rods 22 on both sides of one of the protective frames 1, so that the threaded rods 22 rotate in the threaded tube 26, and drive the L-shaped plate 23 to rise and slide in the mounting frame 2. At the same time, drive the limiting block 25 to slide in the limiting groove 201. Then, slide the splicing plate 27 on one side of the other protective frame 1 into the corresponding mounting frame 2, so that the splicing plate 27 and the mounting frame 27 are aligned. When the two protective frames 2 overlap, the slots 271 in the splicing plate 27 correspond to the insert rods 24. Then, the threaded rod 22 is rotated so that the L-shaped plate 23 fits against the top surface of the splicing plate 27 and the insert rods 24 are inserted into the slots 271. This allows the splicing plate 27 to be installed in the mounting frame 2, and the two protective frames 1 can be combined to facilitate the use of the lithium battery body 11. There is no need to use aluminum-plastic composite film to wrap it, which facilitates the assembly and installation and improves the efficiency of installation and disassembly. At the same time, there is a gap between the two protective frames 1 after installation so that the heat generated by the lithium battery body 11 can be discharged from the heat dissipation groove 101 to avoid overheating and safety hazards.

[0026] Next, by pulling the lever 3, the moving rod 31 drives the moving ring 32 to slide in the fixed groove 103. At the same time, the spring 33 is squeezed, causing the moving rod 31 to disengage from the first positioning rod 21 and the second positioning rod 28. This makes it easier to disassemble and install the mounting frame 2 and the splicing plate 27. When the bottom or top protective frame 1 does not need to use the mounting frame 2 and the splicing plate 27, it can be easily disassembled, thereby saving installation space and not creating more usable space.
