Description

Technical Field

[0001] The present invention relates to the technical field of lithium-ion batteries, and in particular to a lithium-ion battery BMS management box. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery). It mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charge and discharge process, Li+ is embedded and de-embedded between the two electrodes: when charging, Li+ is de-embedded from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; when discharging, the opposite is true. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium as electrodes and are the representative of modern high-performance batteries. Real lithium batteries are rarely used in daily electronic products due to their high risk. Petroleum coke and graphite are non-toxic and abundant in resources as negative electrode materials. Lithium ions are embedded in carbon, which overcomes the high activity of lithium and solves the safety problems of traditional lithium batteries. The positive electrode LixCoO2 can achieve a high level in charge and discharge performance and life, reducing costs.

[0003] However, the existing battery BMS management system still has some shortcomings:

[0004] 1. When the battery BMS management system is operating normally, the distance between the internally installed devices and the inner wall of the management system is relatively close. The heat generated by the devices will be transferred to the management system, resulting in a higher surface temperature. The space inside the management system cannot be adjusted according to the footprint of the devices.

[0005] 2. The battery BMS management system is usually equipped with multiple heat dissipation holes for heat dissipation. However, the heat inside the system is relatively high, and the heat dissipation efficiency of multiple heat dissipation holes is relatively poor. A large amount of heat still accumulates inside the system for a long time, which may cause damage to some components and affect the normal operation of the system.

[0006] 3. When the battery BMS management system is installed in a new environment, the multiple heat dissipation holes cannot be blocked, resulting in a large amount of dust floating from the heat dissipation holes to the inside of the system during its transportation. The multiple heat dissipation holes cannot be opened when the battery BMS management system is in use. Summary of the invention

[0007] The purpose of the present invention is to provide a lithium-ion battery BMS management box to solve the problem that the heat generated by the device proposed in the above background technology will be transferred to the management system, resulting in a high surface temperature, poor heat dissipation efficiency of multiple heat dissipation holes, and a large amount of heat will still accumulate inside the system for a long time, thereby causing damage to some components and the problem that multiple heat dissipation holes cannot be opened when the battery BMS management system is used.

When no pressure is applied to the auxiliary block 6, the auxiliary block 6 will always remain motionless inside the auxiliary groove 5, thereby sliding the two auxiliary blocks 6 relatively, and the distance between the two mounting frames 7 will gradually approach, which will then drive the corresponding two extrusion plates 9 to approach each other. The shelf 10 and the extrusion plate 9 respectively squeeze one side of the two extension plates 12, so that the distance between the two extension plates 12 can be adjusted.

[0035] Embodiment 2:

[0036] Based on the first embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a shelf 14 is fixedly installed on one side of one of the auxiliary plates 8, and two processing slots 36 are provided on one side of the storage rack 20, wherein a plurality of protrusions 11 are inserted and connected on the other sides of the two extrusion plates 9, and the positions of the plurality of protrusions 11 are arranged at equal intervals, and extension plates 12 are slidably installed inside the two adjacent auxiliary slots 5, and a plurality of ventilation holes 13 are provided on one side of the two extension plates 12, and the positions of the plurality of ventilation holes 13 are arranged at equal intervals, and a baffle plate 22 is snap-connected on one side of one of the extension plates 12, and a fixing frame 23 is snap-connected on one side of the other extension plate 12, and pressing the power switch installed on the surface of the management box 1 will drive the two micro fans 21 electrically connected thereto to work, and the wind blown by the micro fans 21 will continue to blow to the interior of the management box 1 through the plurality of ventilation holes 13, and the heat generated inside the management box 1 can be blown to the external environment through the heat dissipation holes 26.

[0037] Embodiment three:

[0038] On the basis of the first and second embodiments, Figure 1 , Figure 6 and Figure 7As shown, both sides of the fixing frame 23 are provided with sliding grooves, and the extension blocks 24 are slidably installed inside the two sliding grooves. The two sides of the baffle plate 22 are fixedly connected to one side of the two extension blocks 24 respectively, and the positions of the two extension blocks 24 are corresponding. One end of the rotating column 35 is rotatably connected with a threaded rod 17, and one end of the threaded rod 17 is rotatably connected to one side of the extension frame 16. An auxiliary sleeve 18 is threadedly sleeved on one end of the threaded rod 17, and the top of the auxiliary sleeve 18 is inserted and connected with a limiting column 19, and the top of the limiting column 19 is inserted and connected with a storage rack 20. A supporting groove 32 is provided on the top of the mounting cover 4, and a processing pad 25 is installed in the support groove 32. The top of the processing pad 25 is provided with a plurality of heat dissipation holes 26, and a limiting frame 2 is fixedly installed on one side of the top of the mounting cover 4. 7. A folding plate 28 is movably installed on one side of the limiting frame 27, and two hooks 29 are movably hinged on one side of the folding plate 28. A support plate 30 is fixedly installed on the other side of the top of the installation cover 4. Two slots 31 are provided on one side of the support plate 30, and the two slots 31 are respectively engaged with the two hooks 29. The present invention is provided with a processing pad 25, a heat dissipation hole 26, a slot 31, a limiting frame 27, a folding plate 28 and a hook 29. The folding plate 28 can be movable on one side of the limiting frame 27. When the folding plate 28 is pulled outward, the area of ​​the folding plate 28 exposed to the external environment will gradually increase, and the two hooks 29 will gradually approach the support plate 30, and the two hooks 29 will be embedded in the inside of the two slots 31 for engagement, thereby limiting and fixing the folding plate 28.

[0039] Working principle: The material of the silicone pad 2 is silicone, so the surface is relatively soft. The bottom surface of the silicone pad 2 is in contact with the installation surface, which can reduce the extrusion force on the bottom surface of the management box 1 and avoid a large degree of wear on the bottom surface of the management box 1. The bottom surface of the installation cover 4 is installed together with the top of the management box 1. The auxiliary block 6 can slide freely inside the auxiliary groove 5. The friction between the two is relatively large. When no pressure is applied to the auxiliary block 6, the auxiliary block 6 will always remain motionless inside the auxiliary groove 5, thereby sliding the two auxiliary blocks 6 relative to each other, and the distance between the two mounting frames 7 will gradually close, which will then drive the corresponding two extrusion plates 9 to lean against each other. When the extrusion plate 9 moves, it will also drive the multiple protrusions 11 installed on one side thereof to move. The multiple protrusions 11 will squeeze the extension plate 12, exert pressure on the extension plate 12, and the extension plate 12 will gradually move forward. Another shelf 10 will also exert pressure on another extension plate 12, and the extension plate 12 will also gradually move forward. The distance between the two extension plates 12 will gradually approach each other, and the distance between the two extension plates 12 can therefore be adjusted, so that the device can be installed in the middle position of the two extension plates 12. The materials of the two extension plates 12 are both silicone, which has good enough softness and will not cause wear when in contact with the device. The distance between the device and the inner wall of the management box 1 is relatively far, thereby preventing the heat generated by the device from being transferred to the management system, resulting in a higher surface temperature. The space inside the management system can be effectively adjusted according to the footprint of the device. Starting the motor 15 will drive the threaded rod 17 connected to the output shaft of the motor 15 to rotate, thereby causing the auxiliary sleeve 18 threadedly sleeved on one end of the threaded rod 17 to move back and forth, thereby driving the storage rack 20 to move. Pressing the power switch installed on the surface of the management box 1 will drive the two micro fans 21 electrically connected to it to work, and the wind blown by the micro fans 21 will continue to blow to the management through multiple ventilation holes 13. The heat generated inside the management box 1 can be blown to the external environment through the heat dissipation holes 26, and the heat can be dissipated at different positions inside the management box 1, thereby improving the heat dissipation efficiency of the management system. When the extension plate 12 moves, the retaining plate 22 will also slide inside the slide groove through the two extension blocks 24, and the retaining plate 22 will gradually be embedded in the interior of the fixing frame 23. The coordinated use of the two can protect the top of the device, avoid the external pressure directly squeezing the surface of the device and causing wear, and improve the service life of the device and the management box 1. The folding plate 28 can move on one side of the limit frame 27, and the folding plate 28 can be pulled outward.The area of ​​the folding plate 28 exposed to the external environment will gradually increase, and the two hooks 29 will gradually approach the support plate 30, and the two hooks 29 will be embedded in the two slots 31 for engagement, so as to limit and fix the folding plate 28. At this time, the bottom surface of the folding plate 28 is in contact with the surface of the processing pad 25, and the multiple heat dissipation holes 26 can be firmly covered. The sealing between the two is strong, and the multiple heat dissipation holes 26 can be covered in time when the management box 1 is not in use, so as to avoid a large amount of dust floating into the interior of the management box 1 through the heat dissipation holes 26 and causing device contamination. When the heat dissipation holes 26 need to be used, the two hooks 29 are separated from the slots 31, and the folding plate 28 is slid in the reverse direction. The folding plate 28 will gradually roll up, so that the multiple heat dissipation holes 26 are exposed to the external environment, and the multiple heat dissipation holes 26 can dissipate the heat generated inside the management box 1.
