Description

Technical Field

[0001] The present invention relates to the technical field of lithium-ion battery packs, and particularly to an installation device for a lithium-ion battery pack with a thermal control function. Background Technique

[0002] A lithium-ion battery is a secondary battery (rechargeable battery). It mainly works by the movement of lithium ions between the positive and negative electrodes. During the charge and discharge process, Li+ embeds and de-embeds between the two electrodes back and forth: during charging, Li+ de-embeds from the positive electrode and embeds into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharging, it is the opposite. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are usually commonly referred to as lithium batteries by people. Batteries generally use materials containing lithium elements as electrodes and are representatives of modern high-performance batteries. However, real lithium batteries are rarely used in daily electronic products due to high danger, and lithium-ion batteries need to be installed in a protective housing for use after assembly.

[0003] After retrieval, it is found that in Chinese patents with the authorized announcement numbers CN109950474B and CN112521779A, lithium-ion batteries, lithium-ion battery separator coatings, lithium-ion battery separators, and lithium-ion batteries are disclosed. The beneficial effects of this patent are as follows: By appropriately designing the OI value OIc of the positive electrode film and the OIa value of the negative electrode film, the present invention can make the kinetics of the positive and negative electrodes of the lithium-ion battery reach the optimal match during the fast charging process, ensure that the lithium-ion battery has a high charging capacity, and at the same time ensure that the lithium-ion battery also has good cycle life and safety during long-term fast charging use. The coating includes core / shell structured ceramic / polymer composite particles, where the ceramic particles are the core and a low-melting-point polymer with a melting temperature of 100 - 200 °C is used as the shell to coat the ceramic particles. After using this coating to coat the base film to make a lithium-ion battery separator with a coating, the ceramic particles can provide high-temperature resistance for the coating and the separator. The low-melting-point polymer material can melt when the battery overheats, closing the pores of the separator to achieve thermal shutdown performance. Moreover, the polymer used is a hydrophobic polymer material, which can prevent the coated ceramic particles from absorbing environmental moisture. Therefore, the water content of the ceramic / polymer composite particles is extremely low, and thus the water content of the coating and the separator prepared is extremely low, which can be as low as below 50 ppm. The coating of the lithium-ion battery separator of the present invention can improve the electrical performance of the lithium-ion battery separator in the battery system and enhance the safety performance and cycle performance of the battery.

[0004] Most of the existing lithium-ion battery packs are simply placed into the inner cavity of the protective housing. This installation method not only causes the lithium-ion battery pack to disconnect from the external connection device when encountering vibration during long-term use, which requires the user to reconnect the lithium-ion battery pack, wasting time and effort. Moreover, when the traditional lithium-ion battery pack is used in winter, it is easy to reduce the internal temperature of the lithium-ion battery pack, resulting in a decrease in the operating efficiency of the lithium-ion battery pack. Therefore, we propose an installation device for a lithium-ion battery pack with a thermal control function, which has the function of being easy to use. Summary of the Invention

[0030] Further, two symmetrically arranged clamping assemblies 5 are provided on the surface of the disc 44. Fixed blocks 6 are fixedly connected to both sides of the inner cavity of the installation box 1. Card slots 61 are opened on both sides of the fixed block 6. The card slots 61 are used in cooperation with the clamping assemblies 5. A thermal control assembly 7 is provided at the bottom of the installation box 1. The thermal control assembly 7 is used in cooperation with the lithium-ion battery pack 2.

[0031] In this embodiment, the clamping assembly 5 includes a connecting block 51 rotatably connected to the disc 44. A moving block 52 is rotatably connected to one side of the connecting block 51. The shape of the moving block 52 is "L". Support rods 53 are rotatably connected to both sides of the inner cavity of the installation box 1. The surface of the support rod 53 is fixedly connected to the moving block 52. A clamping block 54 is fixedly connected to one side of the moving block 52. The clamping block 54 is used in cooperation with the card slot 61. The diameter of the inner cavity of the card slot 61 is larger than that of the clamping block 54. The clamping block 54 is movably connected to the card slot 61. Through the setting of the clamping assembly 5, the lithium-ion battery pack 2 can be quickly installed or disassembled, saving time and effort and improving the operation efficiency of the user.

[0032] In this embodiment, two front and rear symmetrically arranged open structures are opened on one side of the connecting box 3. The open structures are used in cooperation with the clamping assemblies 5. Through the cooperation of the connecting box 3 and the open structures, the clamping assemblies 5 are protected, avoiding the collision of the clamping assemblies 5 during operation and extending the service life of the clamping assemblies 5.

[0033] In this embodiment, the thermal control assembly 7 includes a fixed box 71 fixedly connected to the installation box 1. A heating fan 72 is fixedly connected to the inner cavity of the fixed box 71. A plurality of air ducts 73 are equally spaced and communicated with the top of the fixed box 71. One end of the air duct 73 penetrates into the inner cavity of the installation box 1 and is fixedly connected to a transfer block 74. Through holes 75 are opened on both sides of the fixed box 71. Threading holes 12 are opened on both sides of the fixed box 71. Through the setting of the through holes 75, the heating fan 72 can be regularly ventilated and exhausted, improving the working efficiency of the heating fan 72.

[0034] In this embodiment, limiting grooves 8 are opened on both sides of the inner cavity of the connecting box 3. Limiting blocks 9 are slidably connected to the inner cavities of the limiting grooves 8. One side of the limiting block 9 is fixedly connected to the push plate 42. Through the cooperation of the limiting grooves 8 and the limiting blocks 9, the push plate 42 is limited during operation, avoiding the position deviation of the push plate 42 during operation and improving the stability of the push plate 42.

By using the first wire hole 11 and the second wire hole 13 in cooperation, it is convenient for external power supply devices or connection devices to connect to its internal components, improving the working efficiency of the internal components.

[0037] Working principle: If the user needs to disassemble the lithium-ion battery pack 2, the electric telescopic rod 41 can be activated. The output end of the electric telescopic rod 41 contracts and pushes the push plate 42 to move in the direction of the card slot 61. And through the cooperation of the limiting groove 8 and the limiting block 9, the push plate 42 moves stably. The push plate 42 pushes the fixed rod 43 to move synchronously, and the fixed rod 43 pushes the disc 44 to move synchronously. While the two discs 44 move, they push the two connecting blocks 51 to swing away from each other. The two connecting blocks 51 push the two moving blocks 52 to make synchronous swings with the support rod 53 as the center. The two moving blocks 52 drive the two clamping blocks 54 to move away from the card slot 61, thus releasing the installation state of the lithium-ion battery pack 2 through the card slot 61. On the contrary, by extending the output end of the electric telescopic rod 41 and using the cooperation of the above components, the lithium-ion battery pack 2 can be installed. And the user can activate the heating fan 72. The heating fan 72 transfers the hot air to the transfer block 74 through the air duct 73, and the transfer block 74 then heats the lithium-ion battery pack 2, thus achieving the purpose of thermal control.
