Description

Technical Field

[0001] This utility model relates to the field of battery management device technology, and in particular to a battery management module for base stations. Background Technology

[0002] In the field of wireless communication, base stations are the core nodes for information transmission, and their stable operation is crucial. Base station battery management modules, as key components to ensure continuous power supply to base stations, directly affect the stability and coverage of the entire communication network. In recent years, with the rapid development of communication technology and the expansion of base station deployment, the requirements for battery management modules have also increased. However, some existing battery management modules still have many shortcomings in terms of external and internal structure, which urgently need to be improved.

[0003] A combined battery management module with Chinese patent publication number CN222720544U is disclosed. The battery management module is pushed upward by spring return, and the slide plate and the limiting rod are pushed upward. The limiting rod passes through the limiting hole, which can limit and fix the battery management device inside the base, making it convenient to install and remove the battery management device.

[0004] However, with the increase in power density of battery management modules, heat dissipation problems have become increasingly prominent. Some modules have unreasonable heat dissipation designs, with heat sinks that are too small or poor heat dissipation channels, which can easily cause overheating when the modules are working in high-temperature environments. Secondly, their shock and dust resistance is weak, as the batteries are mostly fixed by rigid connections, making them susceptible to vibration and dust during transportation and installation. At the same time, the battery management modules were not designed with ease of maintenance in mind, making it difficult for maintenance personnel to quickly locate and replace faulty components when the modules malfunction or require maintenance. Utility Model Content

[0005] The present invention proposes a battery management module for base stations, which solves the problems of poor heat dissipation, weak shock and dust resistance, and inconvenient maintenance of existing battery management modules for base stations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A battery management module for a base station includes a protective box. Multiple sets of sliding tracks are arranged on the lower inner side of the protective box, and matching movable plates are slidably connected inside the tracks. A shock absorber is provided at the bottom of the movable plate, and the battery management module body is located on the top of the movable plate. Clamping mechanisms are provided on both sides of the battery management module body inside the protective box, and a removable cover is provided on the top of the protective box. An air inlet and an exhaust outlet are respectively provided on both sides inside the protective box, and heat dissipation mechanisms are provided inside the air inlet and exhaust outlet. A placement slot is provided on one side of the protective box, and multiple sets of interfaces are provided inside the placement slot. An openable and closable door is provided on the side of the interfaces inside the placement slot.

[0008] Preferably, the protective box has fixing plates on both sides, and the fixing plates have multiple sets of mounting holes inside. One side of the protective box has multiple sets of expansion blocks, and the other side of the protective box has an expansion groove that matches the expansion blocks.

[0009] Preferably, the clamping mechanism includes a mounting groove, a damping telescopic rod, a shock-absorbing spring, a clamping plate, and a rubber pad. Multiple sets of mounting grooves are provided on both sides of the inside of the protective box. A damping telescopic rod is provided inside the mounting groove, and a clamping plate is provided on the side of the damping telescopic rod. A shock-absorbing spring is provided on the outside of the damping telescopic rod, and a rubber pad is provided on the side of the clamping plate.

[0010] Preferably, the cover plate has snap-fit ​​grooves on both sides inside, and the protective box has a movable groove at the top inside. The movable groove has snap-fit ​​blocks that match the snap-fit ​​grooves and are movably snapped in place. The snap-fit ​​blocks have multiple sets of return springs located inside the movable groove.

[0011] Preferably, a boss is provided on the top side of the movable groove, and a limit rod is movably installed inside the boss, and a pull groove is provided on the top of the cover plate.

[0012] Preferably, the heat dissipation mechanism includes a cooling fan, a heat sink, and a protective mesh, and a cooling fan is provided inside both the air inlet and the exhaust port. A heat sink is provided on the side of the protective box inside the cooling fan, and a protective mesh is provided on the outside of the air inlet and the exhaust port.

[0013] Preferably, the placement slot is provided with a sliding groove that matches the box door, and the box door is provided with a protruding rod on the outside.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The battery management module used in this base station has air inlets and exhaust outlets on both sides of the protective box. Heat sinks are installed on the side of the protective box inside the cooling fan, which increases the heat dissipation area. High-efficiency heat sinks are used to improve heat dissipation efficiency. At the same time, the optimized air duct design, together with the cooling fan, ensures smooth airflow inside the module and reduces heat accumulation. In addition, the cooling fan can automatically adjust its speed according to the module temperature to achieve precise heat dissipation.

[0016] 2. Shock absorbers are installed at the bottom of the movable plate, and damping telescopic rods and shock-absorbing springs are used on both sides of the battery management module body. The elasticity of the damping telescopic rods and shock-absorbing springs, together with the clamps and rubber pads, limits and fixes the battery management module body.

[0025] 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.

[0026] Example 1

[0027] Reference Figures 1-6 This utility model provides a technical solution: a battery management module for a base station, including a protective box 1. Multiple sets of slide rails 2 are provided on the lower inner side of the protective box 1, and matching movable plates 3 are slidably connected inside the slide rails 2. A shock absorber 4 is provided at the bottom of the movable plate 3, and a battery management module body 5 is provided at the top of the movable plate 3. A cover plate 6 that is easy to disassemble is provided on the top of the protective box 1. An air inlet 7 and an exhaust outlet 8 are respectively provided on both sides inside the protective box 1, and a heat dissipation mechanism is provided inside the air inlet 7 and the exhaust outlet 8. A placement groove 9 is provided on one side of the protective box 1, and multiple sets of interfaces 10 are provided inside the placement groove 9. An openable and closable box door 11 is provided on the side of the interface 10 inside the placement groove 9.

[0028] Reference Figure 1 The protective box 1 has a fixing plate 12 on both sides, and the fixing plate 12 has multiple sets of mounting holes 13 inside. One side of the protective box 1 has multiple sets of expansion blocks 14, and the other side of the protective box 1 has an expansion slot 15 that matches the expansion block 14, which facilitates the expansion connection of multiple sets of protective boxes 1, and facilitates the addition of new functional units or expansion of battery capacity.

[0029] Reference Figure 3 The heat dissipation mechanism includes a cooling fan 26, a heat sink 27, and a protective mesh 28. The air inlet 7 and the exhaust outlet 8 are both equipped with cooling fans 26. The side of the protective box 1 is equipped with a heat sink 27 located inside the cooling fan 26, and the air inlet 7 and the exhaust outlet 8 are equipped with a protective mesh 28 on the outside.

[0030] In a specific implementation, a base station battery management module, when the battery management module is dissipating heat, firstly, the protective box 1 is fixed in a suitable position inside the base station through the mounting holes 13 inside the fixing plate 12. Then, the protective box 1 is extended and connected through the expansion block 14 and the expansion slot 15. After installation, the battery management module body 5 generates a large amount of heat inside the protective box 1. First, the heat sink 27 quickly conducts the heat to the inside of the air inlet 7 and the exhaust port 8. Then, the cooling fan 26 is activated. One end of the cooling fan 26 blows external air into the protective box 1 through the air inlet 7, and the other end of the cooling fan 26 draws the heat inside the protective box 1 and the outside of the heat sink 27 out of the protective box 1 through the exhaust port 8, thus forming multiple sets of circulating heat dissipation air ducts. At the same time, the cooling fan 26 can automatically adjust the speed of the cooling fan according to the temperature of the battery management module body 5 to achieve precise heat dissipation. Through the above operations, smooth airflow inside the module is ensured, reducing heat accumulation.

[0031] Example 2

[0032] Reference Figures 4-6 The difference from Embodiment 1 is that the battery management module body 5 has clamping mechanisms on both sides inside the protective box 1. These clamping mechanisms include mounting slots 16, damping telescopic rods 17, shock-absorbing springs 18, clamping plates 19, and rubber pads 20. Multiple sets of mounting slots 16 are provided on both sides inside the protective box 1. Damping telescopic rods 17 are installed inside the mounting slots 16, and clamping plates 19 are provided on the sides of the damping telescopic rods 17. Shock-absorbing springs 18 are provided on the outer sides of the damping telescopic rods 17, and rubber pads 20 are provided on the sides of the clamping plates 19. The cover plate 6 has snap-fit ​​grooves 21 on both sides inside, and... The upper part of the protective box 1 is provided with a movable groove 22. Inside the movable groove 22, there is a snap-fit ​​block 23 that matches the snap-fit ​​groove 21 and is movably snapped in place. The inner side of the snap-fit ​​block 23 is provided inside the movable groove 22 with multiple sets of return springs 32. The top side of the movable groove 22 is provided with a boss 24, and a limit rod 25 is movably installed inside the boss 24. The top of the cover plate 6 is provided with a pull groove 31. The placement groove 9 is provided with a sliding groove 29 that matches the box door 11. The outer side of the box door 11 is provided with a protruding rod 30. The openable box door 11 effectively protects the interface 10 from dust.

[0033] In specific implementation, for a base station battery management module, when maintenance or replacement is required, firstly, manually pull outward the latching block 23. The return spring 32 deforms under the pulling force. Next, press the limiting rod 25 inside the boss 24, thereby locking the limiting rod 25 onto the side of the latching block 23. Immediately afterwards, remove the cover plate 6 through the pull groove 31 to facilitate maintenance of the inside of the protective box 1 and the battery management module body 5. If the battery management module body 5 needs to be disassembled and replaced, manually remove the battery management module body 5, and then place the new battery management module body 5 on top of the movable plate 3. The clamping plate is then pushed by the elastic action of the damping telescopic rod 17 and the shock-absorbing spring 18. 19. Rubber pads 20 are tightly clamped to both sides of the battery management module body 5. Then, the cover plate 6 is placed on top of the protective box 1. The limiting rod 25 on the side of the snap-fit ​​block 23 is pulled out. Under the elastic action of the return spring 32, the snap-fit ​​block 23 is quickly pushed to snap into the snap-fit ​​groove 21, thereby realizing the stable connection of the cover plate 6 to the top of the protective box 1. In addition, during the transportation and installation of the battery management module body 5, the bottom of the movable plate 3 is equipped with a shock absorber 4, which, together with the damping telescopic rod 17 and the shock-absorbing spring 18, effectively improves the shock resistance of the battery management module body 5. Through the above operations, the disassembly time is reduced, making maintenance more convenient. At the same time, the shock resistance and dustproof performance of the battery management module are also improved.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
