Description

TECHNICAL FIELD

[0001] The utility model relates to lithium battery PACK technical field especially relates to lithium battery PACK insulation quick locking frame. BACKGROUND

[0002] Lithium battery PACK refers to the battery pack formed by combining and packaging multiple lithium ion battery monomers, used to provide higher voltage and capacity to meet various application requirements such as electric vehicles, energy storage systems, portable devices, etc., and lithium battery PACK generally needs to be used with a structure frame to provide mechanical support and insulation protection to ensure safety, but the structure frame used by most lithium battery PACK in the prior art still has problems to be solved.

[0003] Most of the structure frames used by lithium battery PACK in the prior art lock the frame and lithium battery PACK through the cooperation of bolts and nuts, which takes a long time to assemble, and each bolt needs to be tightened one by one, especially when there are a large number of battery modules, which takes a lot of time, and when adjusting or disassembling on site, it may be cumbersome to tighten the bolts again, which is not convenient for quick maintenance or disassembly, affecting the efficiency of assembly work, so it is necessary to design a lithium battery PACK insulation quick locking frame to solve the above problems. SUMMARY

[0004] The utility model discloses a lithium battery PACK insulation quick locking frame is provided to solve the problem existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A lithium battery pack insulation quick-locking frame includes an upper frame and a lower frame at the bottom of the upper frame. L-shaped fixing plates are fixedly connected to both sides of the upper and lower frames. A locking plate is fixedly connected to the outer wall of the L-shaped fixing plate on the lower frame, and a locking groove is formed at the top of the locking plate. A mounting box is fixedly connected to the outer wall of the L-shaped fixing plate on the upper frame. A square frame plate is fixedly connected to the inner wall of the mounting box. Movable plates are provided on the two square frame plates on their opposite sides, and the movable plates are slidably connected to the inner wall of the mounting box. Each of the two moving plates has a limiting plate fixedly connected to its closest side. One side of the limiting plate is inclined. Each of the two moving plates has two first guide rods fixedly connected to its farthest side. The first guide rods pass through the mounting box and are slidably connected to the mounting box. A spring is fitted onto each first guide rod. A slider is fixedly connected to one side of each moving plate and is slidably connected to the mounting box. A round rod is fixedly connected to the slider on its farthest side. The two round rods are fitted onto the same L-shaped plate, which has two symmetrically distributed inclined grooves. The round rod is set in the inclined groove. Due to the technical means of restricting the position between the locking plate and the mounting box by the cooperation of the locking plate, locking groove, and limiting plate, when the limiting plate is in the locking groove, the position between the locking plate and the mounting box can be fixed, thus locking the upper and lower frames and completing the assembly work. During disassembly, raising the L-shaped plate allows the two limiting plates to move away from each other and out of the locking groove, separating the mounting box and the locking plate, and thus separating the upper and lower frames. This effectively solves the problem mentioned in the background art that most existing lithium battery packs use bolts and nuts to lock the frame and the lithium battery pack, which requires a long assembly time. Each bolt needs to be tightened individually, especially with a large number of battery modules, which is time-consuming. Re-tightening bolts during on-site adjustment or disassembly can be cumbersome, hindering quick maintenance or disassembly and affecting assembly efficiency. Therefore, this technology effectively simplifies the assembly and disassembly process, enabling rapid fixing and disassembly of the lithium battery pack structure, significantly shortening assembly time and improving maintenance convenience.

[0007] Preferably, a handle is fixedly connected to the top of each of the two L-shaped plates.

[0008] Preferably, the top of both ends of the mounting box is fixedly connected to a second guide rod, the L-shaped plate is sleeved on the two second guide rods, and the L-shaped plate is slidably connected to the second guide rods.

[0009] Preferably, three first positioning rods are fixedly connected to the bottom of both ends of the upper frame, and three positioning slots are opened at the top of both ends of the lower frame, the positioning slots being adapted to the first positioning rods.

[0010] Preferably, insulating pads are provided in the lithium battery mounting slots of both the upper and lower frames.

[0011] Preferably, two mounting plates are provided on both sides of the lower frame. The mounting plates are fixedly connected to the outer wall of the L-shaped fixing plate on the lower frame. A second positioning rod is fixedly connected to the top of each of the four mounting plates. Each of the four second positioning rods is fitted with a positioning plate. The second positioning rod is adapted to the hole on the positioning plate. The two positioning plates at the same end are fixedly connected to the outer wall of the L-shaped fixing plate on the upper frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing a technical means that uses locking plates, locking grooves, and limiting plates to restrict the position between the locking plate and the mounting box, the position between the locking plate and the mounting box can be fixed when the limiting plate is in the locking groove, thus locking the upper and lower frames and completing the assembly work. During disassembly, raising the L-shaped plate allows the two limiting plates to move away from each other and out of the locking groove, separating the mounting box and the locking plate, and thus separating the upper and lower frames. This effectively solves the problem mentioned in the background art that most existing lithium battery PACKs use bolts and nuts to lock the frame and the lithium battery PACK together, which requires a long assembly time. Each bolt needs to be tightened individually, especially when there are a large number of battery modules, which is time-consuming. On-site adjustment or disassembly can also be cumbersome to retighten the bolts, which is not conducive to quick maintenance or disassembly and affects the efficiency of the assembly work. Therefore, this technology effectively simplifies the assembly and disassembly process, enables the quick fixing and disassembly of the lithium battery PACK structure, significantly shortens the assembly time, and improves the convenience of maintenance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-6A lithium battery pack insulation quick-locking frame includes an upper frame 1, a lower frame 2 at the bottom of the upper frame 1, L-shaped fixing plates 3 fixedly connected to both sides of the upper frame 1 and the lower frame 2, a locking plate 4 fixedly connected to the outer wall of the L-shaped fixing plate 3 on the lower frame 2, a locking groove 5 opened at the top of the locking plate 4, a mounting box 6 fixedly connected to the outer wall of the L-shaped fixing plate 3 on the upper frame 1, a square frame plate 7 fixedly connected to the inner wall of the mounting box 6, and two movable plates 8 provided on the opposite sides of the two square frame plates 7. The movable plates 8 are slidably connected to the inner wall of the mounting box 6. On the sides of the two moving plates 8 that are close to each other, a limiting plate 9 is fixedly connected. One side of the limiting plate 9 is inclined. On the sides of the two moving plates 8 that are far apart from each other, two first guide rods 10 are fixedly connected. The first guide rods 10 pass through the mounting box 6 and are slidably connected to the mounting box 6. The first guide rods 10 are fitted with springs 11. A slider 12 is fixedly connected to one side of the moving plate 8 and is slidably connected to the mounting box 6. A round rod 13 is fixedly connected to the slider 12 on the side away from the moving plate 8. The two round rods 13 are fitted with the same L-shaped plate 14. Two symmetrical openings are made on the L-shaped plate 14. The inclined grooves 15 are distributed, and the round rods 13 are set within the inclined grooves 15. Due to the technical means of restricting the position between the locking plate and the mounting box through the cooperation of the locking plate, locking groove, and limiting plate, when the limiting plate is in the locking groove, the position between the locking plate and the mounting box can be fixed, thus locking the upper and lower frames and completing the assembly work. During disassembly, raising the L-shaped plate allows the two limiting plates to move away from each other and out of the locking groove, separating the mounting box and the locking plate, and thus separating the upper and lower frames. This effectively solves the problem mentioned in the background art. In existing technologies, most lithium battery packs use a structural frame that is locked to the lithium battery pack with bolts and nuts. Assembly takes a long time, and each bolt needs to be tightened one by one. This is especially time-consuming when there are a large number of battery modules. When adjusting or disassembling on site, retightening the bolts can be cumbersome, which is not conducive to quick maintenance or disassembly and affects the efficiency of assembly work. This technology effectively simplifies the assembly and disassembly process, which can quickly fix and disassemble the lithium battery pack structure, significantly shorten the assembly time, and improve the convenience of maintenance.

[0023] In this utility model, handles 16 are fixedly connected to the top of both L-shaped plates 14.

[0024] In this utility model, the top of both ends of the mounting box 6 are fixedly connected with second guide rods 17. The L-shaped plate 14 is sleeved on the two second guide rods 17. The L-shaped plate 14 is slidably connected to the second guide rods 17. When the L-shaped plate 14 moves, it will move along the second guide rods 17 to ensure the stability of the L-shaped plate 14 when it moves.

[0025] In this utility model, three first positioning rods 18 are fixedly connected to the bottom of both ends of the upper frame 1, and three positioning grooves 19 are opened at the top of both ends of the lower frame 2. The positioning grooves 19 are adapted to the first positioning rods 18, and the upper frame 1 and the lower frame 2 are positioned by the cooperation of the first positioning rods 18 and the positioning grooves 19.

[0026] In this invention, insulating pads 23 are provided in the lithium battery mounting slots of both the upper frame 1 and the lower frame 2.

[0027] In this utility model, two mounting plates 20 are provided on both sides of the lower frame 2. The mounting plates 20 are fixedly connected to the outer wall of the L-shaped fixing plate 3 on the lower frame 2. The top of each of the four mounting plates 20 is fixedly connected to a second positioning rod 21. Each of the four second positioning rods 21 is fitted with a positioning plate 22. The second positioning rods 21 are adapted to the holes on the positioning plates 22. The two positioning plates 22 at the same end are fixedly connected to the outer wall of the L-shaped fixing plate 3 on the upper frame 1.

[0028] Working Principle: During use, the lithium battery pack is placed in the mounting slots on the upper frame 1 and lower frame 2, contacting the insulating pad 23 for insulation and safety. The first positioning rod 18 is inserted into the positioning slot 19 to position the upper frame 1 and lower frame 2. The positioning plate 22 is then fitted onto the second positioning rod 21 for further positioning, ensuring accurate positioning between the upper frame 1 and lower frame 2. The mounting box 6 is then fitted onto the locking plate 4, and the upper frame 1 is pressed down, causing it to descend. The limiting plate 9 contacts the locking plate 4. Continuing to descend the mounting box 6, the two limiting plates 9 move away from each other due to the restriction of the locking plate 4. The movement of the limiting plates 9 causes the moving plate 8 to move, which in turn moves the first guide rod 10. The movement of the moving plate 8 also compresses the spring 11, causing it to contract. When the limiting plate 9 moves to the position of the locking slot 5, the contracted spring 11... When the plates extend, the two movable plates 8 can move closer together, which in turn allows the two limiting plates 9 to move closer together and engage in the locking groove 5, thus completing the locking. This restricts the position between the locking plate 4 and the mounting box 6, ensuring the stability of their positions, which in turn ensures the stability of the position between the upper frame 1 and the lower frame 2, completing the assembly. When disassembly is required, pull the handle 16 to raise it. The handle 16 will then raise the L-shaped plate 14, which will press against the round rod 13, causing it to move. The round rod 13 will then move the slider 12, which in turn will move the movable plate 8. Therefore, the round rod 13 can only move laterally. When the L-shaped plate 14 rises, the two round rods 13 will move away from each other, allowing the two limiting plates 9 to move away from each other again and be removed from the locking groove 5, thus separating the upper frame 1 and the lower frame 2.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
