Description

Technical Field

[0001] This utility model relates to the field of lithium battery protection technology, and more specifically to a lithium battery pack protection structure. Background Technology

[0002] Lithium batteries are batteries that contain lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in their electrochemical system. BMS, or battery management system, is the link between the battery and the user. The main target of BMS is secondary batteries, and its purpose is to improve battery utilization, prevent overcharging and over-discharging, extend battery life, and monitor battery status.

[0003] The shortcomings of existing technologies: Existing lithium battery packs do not use storage overcharge protection, which usually has some problems. When stored, lithium battery packs are easily damaged by collisions or drops, causing the internal battery solution to leak out. In addition, the internal storage box of existing lithium battery packs is usually sealed and not airtight, which is not conducive to the heat dissipation of lithium battery packs. To address these issues, we propose a lithium battery pack protection structure that is easy to disassemble and assemble.

[0004] Therefore, there is a need to provide a lithium battery pack protection structure to solve the problems mentioned above. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lithium battery pack protection structure to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a lithium battery pack protection structure, including a storage box, an opening and closing cover movably connected to the top of the storage box, a handle fixedly connected to the middle of the top of the opening and closing cover, a smart lock fixedly connected to the top of the opening and closing cover near the right side, a cooling fan fixedly connected to the right side of the storage box near the bottom, a ventilation plate fixedly connected to the left side of the storage box near the bottom, and a lithium battery pack body movably arranged inside the storage box.

[0007] The lithium battery pack protection structure also includes:

[0008] A limiting component is provided in the center of the storage box for storing the main body of the lithium battery pack.

[0009] A cooling component is disposed on both sides of the limiting component and is used to cool the environment at the limiting component.

[0010] A buffer assembly is disposed between the limiting assembly and the lithium battery pack body for buffering and protecting the lithium battery pack body.

[0011] Preferably, the buffer component includes:

[0012] Two limiting blocks are provided, with telescopic rods fixedly connected to the top of each limiting block and sliding rods fixedly connected to the opposite ends of the two limiting blocks. Buffer springs are movably sleeved on the outer walls of each telescopic rod. Support plates are fixedly connected to the top of each telescopic rod, with the top of the support plate movably connected to the bottom of the lithium battery pack body. Dampers are fixedly connected to the bottom of the support plate near both sides, and the bottom ends of the two dampers are fixedly connected to the inner bottom of the limiting assembly.

[0013] A guiding mechanism is provided between the support plate and the slide rod to guide the vibration of the support plate.

[0014] Preferably, the guiding mechanism includes two collars, the middle of which is movably sleeved on the outer wall of the slide rod, and a compression spring is movably sleeved on the outer wall of the slide rod between the two collars. A first movable seat is fixedly connected to the top of each of the two collars, a guide rod is movably sleeved on the middle of each of the two first movable seats, and a second movable seat is movably sleeved on the top of each of the two guide rods. The top of each of the two second movable seats is fixedly connected to the bottom of the support plate.

[0015] Preferably, the cooling component includes a condensate tank, a water pump is fixedly connected to the front side of the condensate tank, an inlet pipe is fixedly connected to one end of the water pump, a circulation pipe plate is fixedly connected to one end of the inlet pipe, an outlet pipe is fixedly connected to the rear side of the circulation pipe plate near the bottom, and one end of the outlet pipe is fixedly connected to the rear side of the condensate tank.

[0016] Preferably, the outer wall of the circulation tube plate is fixedly connected to both sides of the inner wall of the limiting component, and protective soft plates are fixedly connected to both the front and rear sides of the inner wall of the limiting component.

[0017] Preferably, the limiting component includes a placement seat, with sleeve rods fixedly connected to both sides of the top of the placement seat, and a movable rod movably sleeved at one end of each of the two sleeve rods. A fixing plate is fixedly connected to the bottom end of the movable rod, and one side of the fixing plate is fixedly connected to the outer wall of the lithium battery pack body. A limiting plate is fixedly connected to the top end of the movable rod.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. This utility model, by incorporating a buffer assembly, places the lithium battery pack body at the limiting assembly within the storage box. When the lithium battery pack body is subjected to collision and vibration during storage, the lithium battery pack body drives the support plate to move downwards. Subsequently, under the movable connection of the first and second movable seats, the two guide rods rotate relative to each other, thereby causing the two collars to slide relative to each other on the outer wall of the slide rod, compressing the compression spring. This provides initial buffering against the vibration of the lithium battery pack body. Furthermore, with the support of the limiting block, the support plate moves downwards, compressing the buffer spring and the telescopic rod, further buffering the vibration of the lithium battery pack body. This facilitates stable support and protection against vibration of the lithium battery pack body under the action of the damper.

[0020] 2. This utility model, by providing a limiting component, allows the movable rod to move up and down in the middle of the sleeve rod under the fixed connection of the fixed plate when the main body of the lithium battery pack vibrates. Under the limiting of the limiting plate, it helps to restrict the movement of the main body of the lithium battery pack in the vertical direction, and works with the buffer component to provide buffer protection.

[0021] 3. This utility model incorporates a cooling component. When dissipating heat from the storage environment of the lithium battery pack, a water pump is activated, transferring condensate from the condensate tank to the circulation tube plate via the inlet pipe. As the condensate passes through the annular pipe of the circulation tube plate, it carries away the heat from the lithium battery pack. The condensate then flows back to the condensate tank via the outlet pipe. By activating the cooling fan, the heat is dissipated to the external environment through the ventilation plate. This effectively cools the storage environment of the lithium battery pack, ensuring that the lithium battery pack does not bulge due to excessive temperature during storage.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The lithium battery pack protection structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Specific Implementation Example 1

[0029] Please see Figure 1-2 and Figure 4 This utility model is a lithium battery pack protection structure, including a storage box 1. A hinged cover 2 is movably connected to the top of the storage box 1. A handle 3 is fixedly connected to the middle of the top of the hinged cover 2. A smart lock 4 is fixedly connected to the right side of the top of the hinged cover 2. A cooling fan 5 is fixedly connected to the right side of the storage box 1 near the bottom. A ventilation plate 6 is fixedly connected to the left side of the storage box 1 near the bottom. A lithium battery pack body 11 is movably disposed inside the storage box 1. The lithium battery pack protection structure also includes a buffer assembly 8, which is disposed between a limiting assembly 9 and the lithium battery pack body 11 for buffering and protecting the lithium battery pack body 11. The buffer assembly 8 includes:

[0030] Two limiting blocks 804 are provided, each with a telescopic rod 805 fixedly connected to its top. A sliding rod 808 is fixedly connected to the opposite end of each limiting block 804. A buffer spring 803 is movably sleeved on the outer wall of each telescopic rod 805. A support plate 801 is fixedly connected to the top of each telescopic rod 805. The top of the support plate 801 is movably connected to the bottom of the lithium battery pack body 11. Dampers 802 are fixedly connected to both sides of the bottom of the support plate 801. The bottom ends of the two dampers 802 are fixedly connected to the inner bottom of the limiting assembly 9. A guide mechanism is provided between the support plate 801 and... Between the slide rods 808, a guiding mechanism is used to guide the vibration of the support plate 801. The guiding mechanism includes two collars 806, the middle of which is movably sleeved on the outer wall of the slide rod 808. A compression spring 807 is movably sleeved on the outer wall of the slide rod 808 between the two collars 806. The top of each of the two collars 806 is fixedly connected to a first movable seat 809. The middle of each of the two first movable seats 809 is movably sleeved on a guide rod 810. The top of each of the two guide rods 810 is movably sleeved on a second movable seat 811. The top of each of the two second movable seats 811 is fixedly connected to the bottom of the support plate 801.

[0031] Specifically: When the lithium battery pack body 11 is subjected to impact and vibration during storage, the lithium battery pack body 11 drives the support plate 801 to move downward. Then, under the movable connection of the first movable seat 809 and the second movable seat 811, it drives the two guide rods 810 to rotate relative to each other. This causes the two collars 806 to slide relative to each other on the outer wall of the slide rod 808, compressing the compression spring 807, which provides initial buffering for the vibration of the lithium battery pack body 11. Then, under the support of the limiting block 804, the support plate 801 moves downward to compress the buffer spring 803 and the telescopic rod 805, which further buffers the vibration of the lithium battery pack body 11. By turning on the cooling fan 5, the heat is discharged to the external environment through the ventilation plate 6. Specific Implementation Example 2

[0033] Please see Figures 1-3Based on the first specific embodiment, it also includes a limiting component 9, which is located in the middle of the storage box 1 and is used to place and store the lithium battery pack body 11; and a cooling component 7, which is located on both sides of the limiting component 9 and is used to cool the environment at the limiting component 9. The cooling component 7 includes a condensate tank 701, a water pump is fixedly connected to the front side of the condensate tank 701, an inlet pipe 702 is fixedly connected to one end of the water pump, a circulation pipe plate 703 is fixedly connected to one end of the inlet pipe 702, and an outlet pipe 704 is fixedly connected to the rear side of the circulation pipe plate 703 near the bottom. One end of 04 is fixedly connected to the rear side of the condensate tank 701. The outer wall of the circulation tube plate 703 is fixedly connected to both sides of the inner wall of the limiting component 9. Protective soft plates 10 are fixedly connected to both the front and rear sides of the inner wall of the limiting component 9. The limiting component 9 includes a placement seat 901. Sleeve rods 903 are fixedly connected to both sides of the top of the placement seat 901. Movable rods 904 are movably sleeved at one end of each sleeve rod 903. Fixed plate 902 is fixedly connected to the bottom end of the movable rod 904. One side of the fixed plate 902 is fixedly connected to the outer wall of the lithium battery pack body 11. Limiting plate 905 is fixedly connected to the top of the movable rod 904.

[0034] Specifically: Turn on the water pump to transfer the condensate in the condensate tank 701 to the circulation tube plate 703 through the inlet pipe 702. When passing through the annular pipe of the circulation tube plate 703, the condensate carries away the heat from the lithium battery pack body 11. The condensate flows back to the condensate tank 701 through the outlet pipe 704.

[0035] The working principle of this utility model is as follows: The lithium battery pack body 11 is placed in the limiting component 9 inside the storage box 1. When the lithium battery pack body 11 is subjected to collision and vibration during storage, the lithium battery pack body 11 drives the support plate 801 to move downward. Then, under the movable connection of the first movable seat 809 and the second movable seat 811, the two guide rods 810 rotate relative to each other, thereby driving the two collars 806 to slide relative to each other on the outer wall of the slide rod 808, compressing the compression spring 807, which provides initial buffering for the vibration of the lithium battery pack body 11. Then, under the support of the limiting block 804, the support plate 801 moves downward to compress the buffer spring 803 and the telescopic rod 805, which further buffers the vibration of the lithium battery pack body 11. Under the action of the damper 802, the vibration of the lithium battery pack body 11 is further reduced. The mechanism provides stable support and protection. When the lithium battery pack body 11 vibrates, the fixed plate 902 drives the movable rod 904 to move up and down in the middle of the sleeve rod 903. Under the limitation of the limiting plate 905, the movement of the lithium battery pack body 11 in the vertical direction is restricted. It works with the buffer component 8 to provide buffer protection. When the storage environment of the lithium battery pack body 11 is cooled, the water pump is turned on, and the condensate in the condensate tank 701 is transferred to the circulation tube plate 703 through the water inlet pipe 702. When passing through the annular pipe of the circulation tube plate 703, the heat at the lithium battery pack body 11 is carried away. The condensate flows back to the condensate tank 701 through the water outlet pipe 704. By turning on the cooling fan 5, the heat is discharged to the external environment through the ventilation plate 6, thereby cooling the storage environment of the lithium battery pack body 11.
