During use, storage batteries may cause fires for various reasons. Once a fire starts, the consequences are very serious. Therefore, flame-retardant and high-strength battery cases are needed to reduce the probability of batteries causing fires.
[0003] Flame-retardant and high-strength battery cases are structures that house and protect batteries. They can withstand external impacts and collisions, protect batteries from damage, effectively prevent the spread of flames, and reduce the risk of fire. However, the installation positions of existing flame-retardant and high-strength battery cases are fixed and cannot be adapted to different battery sizes. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides a flame-retardant high-strength battery case composite structure, which aims to improve the problem that flame-retardant high-strength battery cases cannot adapt to different battery sizes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant high-strength battery case composite structure, comprising two control rods, each control rod having a control post fixedly connected to its top, a control strip slidably connected to the surface of each control post, and two moving blocks on the surface of each control rod. The right moving block is fixedly connected to the front control rod and slidably connected to the rear control rod, while the left moving block is fixedly connected to the rear control rod and the left moving block is fixedly connected to the front control rod. A fixing strip is rotatably connected to the bottom of the control strip, and a fixing groove is fixedly connected to the bottom of the fixing strip. A cylinder is fixedly connected to the top of the fixing groove, and the cylinder output end is fixedly connected to the rear control rod. Two positioning plates are provided on the top of each of the two moving blocks, and a quick-release assembly is provided on the rear side of the control strip for quickly removing the battery case.
[0006] Preferably, the quick-release assembly includes an outer cover, which is fixedly connected to a fixing groove. A spring is fixedly connected to the inner diameter of the outer cover, and a sliding column is fixedly connected to the top of the spring. The sliding column is slidably connected to the outer cover, and two locking blocks are fixedly connected to the bottom of the sliding column. A connecting plate is provided at the bottom of the fixing groove, and a control groove is opened inside the connecting plate. The outer cover is located on top of the connecting plate.
[0007] Preferably, control blocks are fixedly connected to opposite sides of the two front positioning plates, and the two control blocks are slidably connected to the two moving blocks. Limit rods are slidably connected inside the two control blocks.
[0008] Preferably, the two positioning plates on the rear side are fixedly connected to the movable block, the two movable blocks are slidably connected to the fixed groove, and the top of the movable block on the right side is fixedly connected to two fixed plates.
[0009] Preferably, a limiting plate is fixedly connected to the bottom of the fixing groove, and the limiting plate is located inside the connecting plate.
[0010] Preferably, a threaded rod is rotatably connected to the front side of the rear fixing plate, a worm gear is fixedly connected to the front side of the threaded rod, and the threaded rod is meshed with the control block on the right side.

[0012] Preferably, the moving block is a high-performance bamboo-based fiber composite material, and the positioning plate is a high-performance bamboo-based fiber composite material.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the cylinder pushes the rear control rod and control column to move back and forth, causing the control bar to rotate under the constraint of the fixed bar. The control bar drives the front control rod to move in the opposite direction. The control rod drives the moving block to contract or open to adapt to batteries of different widths. The worm gear is rotated, which drives the threaded rod through the worm wheel, causing the right control block to move back and forth under the control of the right moving block. The left control block is moved synchronously through the limit rod. The control block drives the two front positioning plates to move to adapt to batteries of different lengths, solving the problem that the battery slot cannot adapt to batteries of different sizes.
[0015] 2. In this utility model, a downward pressure is applied to the sliding column. Under the action of this external force, the sliding column overcomes the elastic force of the spring and drives the two locking blocks fixedly connected to its bottom to move downward together. As the sliding column and locking blocks continue to move downward, the locking blocks gradually disengage from the control groove inside the connecting plate, and finally the sliding column rotates ninety degrees. At this time, the force applied to the sliding column can be removed to quickly remove the fixing groove, which solves the problem of inconvenient battery compartment maintenance caused by the troublesome disassembly of the battery compartment.

Detailed Implementation
[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a flame-retardant high-strength battery case composite structure, comprising two control rods 2, each with a control post 6 fixedly connected to its top, and a control strip 5 slidably connected to the surface of each control post 6. Two moving blocks 9 are provided on the surface of each control rod 2; the right moving block 9 is fixedly connected to the front control rod 2 and slidably connected to the rear control rod 2; the left moving block 9 is fixedly connected to the rear control rod 2 and fixedly connected to the front control rod 2; a fixing strip 7 is rotatably connected to the bottom of the control strip 5; a fixing groove 17 is fixedly connected to the bottom of the fixing strip 7; a cylinder 3 is fixedly connected to the top of the fixing groove 17; the output end of the cylinder 3 is fixedly connected to the rear control rod 2; two positioning plates 11 are provided on the top of each moving block 9; and a quick-release assembly is provided on the rear side of the control strip 5 for quickly removing the battery case.
[0027] Specifically, cylinder 3 pushes the rear control lever 2, which in turn drives the control bar 5 to rotate under the control of the fixed bar 7 via the control column 6. The control bar 5 drives the rear control lever 2 and the front control lever 2 to move in opposite directions. The control lever 2 drives the moving block 9 to contract or open, thus fitting batteries of different widths. The worm gear 15 is rotated, which drives the worm wheel 16 to rotate. The worm wheel 16 drives the threaded rod 1 to rotate. The threaded rod 1 drives the right control block 12 to move back and forth under the restriction of the right moving block 9. The right control block 12 moves synchronously with the left control block 12 via the limit rod 13. The control block 12 drives the positioning plate 11 to move, thus fitting batteries of different lengths and solving the problem that the battery slot cannot accommodate batteries of different sizes.
[0028] Reference Figure 1 , Figure 2 and Figure 7 The quick-release assembly includes an outer cover 20, which is fixedly connected to a fixing groove 17. A spring 4 is fixedly connected to the inner diameter of the outer cover 20. A sliding column 21 is fixedly connected to the top of the spring 4. The sliding column 21 is slidably connected to the outer cover 20. Two locking blocks 8 are fixedly connected to the bottom of the sliding column 21. A connecting plate 19 is provided at the bottom of the fixing groove 17. A control groove 14 is opened inside the connecting plate 19. The outer cover 20 is located at the top of the connecting plate 19.
[0029] Specifically, under normal use, the slide column 21 is held in its initial position by the elastic force of the spring 4. At this time, the two locking blocks 8 fixedly connected to the bottom of the slide column 21 are located in the control groove 14 opened inside the connecting plate 19. Through this locking method, the fixing groove 17 is in a stable connection state, applying a downward pressure to the slide column 21. This external force overcomes the elastic force of the spring 4, causing the slide column 21 to start moving downward. Since the slide column 21 is fixedly connected to the two locking blocks 8 at the bottom, the locking blocks 8 will move downward with the slide column 21. As the slide column 21 and the locking blocks 8 continue to move downward, the locking blocks 8 gradually disengage from the control groove 14 inside the connecting plate 19. After the locking blocks 8 are completely disengaged from the control groove 14, the slide column 21 is rotated ninety degrees, and finally the force applied to the slide column is removed. In this way, the fixing groove 17 can be quickly removed, solving the problem of inconvenient maintenance caused by the troublesome disassembly of the battery slot.
[0030] Reference Figures 4-6 On the opposite sides of the two positioning plates 11 on the front, control blocks 12 are fixedly connected. The two control blocks 12 are slidably connected to the two moving blocks 9. Limit rods 13 are slidably connected inside the two control blocks 12.
[0031] Specifically, the moving block 9 controls the movement trajectory of the control block 12, and the limit rod 13 ensures that the two control blocks 12 move synchronously.
[0032] Reference Figures 4-6 The two positioning plates 11 on the rear side are fixedly connected to the moving block 9, and the two moving blocks 9 are slidably connected to the fixing groove 17. The top of the moving block 9 on the right side is fixedly connected to two fixing plates 10.
[0033] Specifically, the moving block 9 causes the positioning plate 11 to move synchronously, the moving block 9 slides on the fixing groove 17, and the moving block 9 is used to fix the fixing plate 10.
[0034] Reference Figure 2 The bottom of the fixed groove 17 is fixedly connected to the limiting plate 18, which is located inside the connecting plate 19.
[0035] Specifically, the fixing groove 17 is used to fix the limiting plate 18, and the limiting plate 18 is used to enhance the structural stability.
[0036] Reference Figures 4-6 The front side of the fixed plate 10 on the rear side is rotatably connected to a threaded rod 1, and the front side of the threaded rod 1 is fixedly connected to a worm gear 16. The threaded rod 1 is meshed with the control block 12 on the right side.
[0037] Specifically, when the worm gear 16 rotates, it drives the threaded rod 1 to rotate, and the threaded rod 1 drives the control block 12 to move.
[0038] Reference Figure 5The worm gear 16 is rotatably connected to the front fixed plate 10, and the top of the worm gear 16 is meshed with a worm 15, which is rotatably connected to the front fixed plate 10.
[0039] Specifically, the fixing plate 10 is used to fix the worm 15 and the worm wheel 16. When the worm 15 rotates, it will drive the worm wheel 16 to rotate.
[0040] Reference Figure 4 The moving block 9 is made of high-performance bamboo-based fiber composite material, and the positioning plate 11 is made of high-performance bamboo-based fiber composite material.
[0041] Specifically, high-performance bamboo-based fiber composite materials have high strength and good flame retardant properties.
[0042] Working principle: When the battery compartment needs to accommodate batteries of different widths, the cylinder 3 drives the rear control rod 2 to move back and forth. The control rod 2 drives the rear control column 6 to move back and forth. The rear control column 6 drives the control bar 5 to rotate under the control of the fixed bar 7. The rotation of the control bar 5 drives the front control rod 2 to move in the opposite direction to the rear control rod 2. When the two control rods 2 move in opposite directions, they will drive the two moving blocks 9 to contract or open, so that the battery compartment can accommodate batteries of different widths.
[0043] When it is necessary to adapt the battery compartment to batteries of different lengths, the worm gear 15 is rotated, which drives the worm wheel 16 to rotate. The worm wheel 16 drives the threaded rod 1 to rotate, and the threaded rod 1 drives the right control block 12 to move back and forth under the control of the right moving block 9. The right control block 12 will drive the left control block 12 to move synchronously through the limit rod 13. The movement of the control block 12 can adjust the position of the two front positioning plates 11, so that the battery compartment can adapt to batteries of different lengths, thereby solving the problem that the battery compartment cannot adapt to batteries of different sizes.
[0044] When the battery compartment needs to be quickly removed, a downward pressure is applied to the slide column 21. The slide column 21 overcomes the elastic force of the spring 4 and begins to move downward. The locking block 8 moves downward with the slide column 21. As the pressure continues, the locking block 8 gradually disengages from the control groove 14 inside the connecting plate 19. After the locking block 8 is completely disengaged from the control groove 14, the slide column 21 is rotated 90 degrees, and then the force applied to the slide column 21 is released. At this time, since the locking block 8 is no longer aligned with the control groove 14 after the slide column 21 is rotated, the fixing groove 17 loses its locking restriction, and it can be quickly removed, effectively solving the problem of inconvenient maintenance caused by the difficulty of disassembling the battery compartment.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
