[0040] Example 1:

[0041] See also Figure 1-5 This embodiment provides a lithium battery 200 with a charging protection structure, which includes: a battery shell 100; a battery 200, the battery 200 is installed in the battery shell 100, and the battery 200 is detachably installed in the battery shell 100; a circuit board 300, the circuit board 300 is installed in the top of the battery shell 100, and a partition heat dissipation device 500 for dissipating heat from the circuit board 300 is installed in the top of the battery shell 100; a battery heat dissipation mechanism 600, the battery heat dissipation mechanism 600 is installed on the outer surface of the battery shell 100, and the battery heat dissipation mechanism 600 is used to dissipate heat from the battery 200.

[0042] The battery shell 100 includes an outer shell 101, a shell cover 102, a connecting bolt 103 and a battery holder 104. The shell cover 102 is detachably installed on the top of the outer shell 101 through the connecting bolt 103, and the battery holder 104 for placing the battery 200 is installed on the inner wall of the bottom end of the outer shell 101; the four corners on the top side of the outer shell 101 are threadedly connected with the connecting bolt 103, and the end of the connecting bolt 103 passes through the shell cover 102 and is threadedly connected to the top side of the outer shell 101.

[0043] Specifically, the battery 200 includes a battery body 201 placed and installed on the top side of the battery holder 104, a negative electrode connecting piece 207 installed on the top side surface of the battery body 201, a positive electrode connecting piece 202 correspondingly installed on the bottom of the battery body 201, a limiting column 203 fitted on the bottom side of the negative electrode connecting piece 207, a limiting shell 205 slidably sleeved on the bottom end surface of the limiting column 203, and a limiting spring 204 installed at the bottom end of the limiting column 203.

[0044] The limiting shell 205 is installed on the top surface of the battery holder 104 , and a limiting spring 204 is installed on the inner wall of the bottom end of the limiting shell 205 . The limiting shell 205 is elastically connected to the limiting column 203 through the limiting spring 204 .

[0045] In actual use, the battery body 201 is placed on the battery seat 104 in the battery shell 100, and the heat insulation plate 503 on the bottom side is pressed down through the shell cover 102. The heat insulation plate 503 drives the negative electrode connecting piece 207 to connect with the top of the battery body 201, and the bottom of the battery body 201 is connected to the positive electrode connecting piece 202. The positive electrode connecting piece 202 is supported by the limiting column 203, and the limiting spring 204 is elastically matched to facilitate the limiting column 203 to connect the positive electrode connecting piece 202 to the positive electrode at the bottom of the battery body 201, thereby improving the connection stability.

[0046] Preferably, the partition heat dissipation device 500 includes a clamping seat 504 fixedly installed on the inner wall of the bottom end of the shell cover 102, an insulation plate 503 arranged on the bottom surface of the clamping seat 504, a heat dissipation fin 501 fixedly passing through the top surface of the shell cover 102, and a heat conducting plate 502 fixedly installed on the inner wall of the top side of the shell cover 102.

[0047] A partition cavity is formed between the heat insulation board 503 and the inner cavity of the housing cover 102 , and a circuit board 300 mounted on the top side of the heat insulation board 503 is disposed in the partition cavity.

[0048] In a specific implementation, the heat insulation plate 503 seals the top cavity of the shell cover 102, and the heat insulation plate 503 realizes the partition between the top circuit board 300 and the battery body 201. Through the cooperation of the heat dissipation fins 501 and the heat conducting plate 502, the heat generated by the circuit board 300 during operation is discharged separately, avoiding the influence of the heat of the bottom battery body 201 on the circuit board 300, ensuring the overall environmental stability of the circuit board 300, and reducing the safety hazards during the operation of the circuit board 300. It solves the problem that when the lithium battery 200 is working, the battery 200 and the circuit board 300 and other components in the lithium battery 200 are mostly integrated together, and there is no separate space partition for the circuit board 300. The temperature difference between the circuit board 300 and the battery 200 increases, and the heat of the battery 200 easily affects the temperature environment of the circuit board 300, and the effective heat dissipation effect of the circuit board 300 is not achieved, thereby reducing the heat dissipation efficiency, thereby improving the overall heat dissipation efficiency of the lithium battery 200.

[0049] The circuit board 300, commonly referred to as a protection board, is conventional technology and plays a crucial role in lithium-ion batteries. Its primary functions include overcharge protection, over-discharge protection, temperature monitoring, short-circuit protection, overcurrent protection, and balancing management, collectively ensuring the safety and performance of lithium-ion batteries. The protection board also monitors battery status, such as voltage, current, and temperature, in real time and transmits this data to external devices via network communications, enabling real-time monitoring and management of the battery 200.

[0050] Furthermore, the battery heat dissipation mechanism 600 includes a partition 601 installed on the inner wall of the outer shell 101, a silicone heat-conducting column 602 fixedly connected to the side surface of the partition 601, heat dissipation holes 603 opened on the front and rear sides of the outer shell 101, a heat dissipation shell 605 fixedly connected to the outer shell 101 by fixing bolts 606, a sealing plate 607 installed on the outer surface of the heat dissipation shell 605, an exhaust hole opened on the sealing plate 607 for heat dissipation, and a heat dissipation fan 604 installed on the heat dissipation shell 605 for heat dissipation; there are two heat dissipation shells 605, the two heat dissipation shells 605 are symmetrically arranged, and fixing bolts 606 are threaded through the four corners of the heat dissipation shell 605, and the ends of the fixing bolts 606 are threadedly connected to the outer surface of the outer shell 101; the partition 601 is evenly arranged on the outer surface of the battery 200, and the partition 601 is used to separate adjacent batteries 200. The silicone heat-conducting columns 602 evenly installed on the surface of the partition 601 fit the battery 200.

[0051] Operation process: install the battery body 201 in the outer shell 101, and the shell cover 102 presses down the heat insulation plate 503, and cooperates with the elasticity of the limit spring 204 to push the limit column 203 to achieve the stability of the internal electrode connection of the battery body 201, and the heat insulation plate 503 realizes the partition between the top circuit board 300 and the battery body 201. Through the cooperation of the heat dissipation fins 501 and the heat conducting plate 502, the heat of the circuit board 300 during operation is discharged separately, avoiding the influence of the heat of the bottom battery body 201 on the circuit board 300, ensuring the overall environmental stability of the circuit board 300, reducing the safety hazards during the operation of the circuit board 300, and solving the problem that when the lithium battery 200 is working, the battery 200 and the circuit board 300 and other components in the lithium battery 200 are mostly integrated together, without a separate space partition for the circuit board 300, and the circuit board 300 is not separated. The temperature difference between the circuit board 300 and the battery 200 increases, and the heat of the battery 200 easily affects the temperature environment of the circuit board 300, failing to achieve effective heat dissipation of the circuit board 300, thereby reducing the heat dissipation efficiency. In this way, the overall heat dissipation efficiency of the lithium battery 200 is improved. After the battery body 201 is placed on the inner wall of the outer shell 101, the battery bodies 201 are separated by the partition 601 to prevent adjacent batteries 200 from contacting and affecting heat dissipation, and the battery body 201 is limited and squeezed by the silicone thermal conductive column 602 to prevent the battery body 201 from shaking. At the same time, the silicone thermal conductive column 602 conducts heat to realize the heat dissipation of the battery body 201, and cooperates with the cooling fan 604 to accelerate the internal gas of the battery body 201 to drive the heat flow, which is convenient for discharge through the heat exhaust hole 68, thereby improving the overall heat dissipation effect of the battery 200.

[0052] Example 2:

[0053] Reference Figure 1 、 Figure 3 and Figure 5This embodiment is different from the first embodiment in that: the dustproof sealing component 700 is arranged and installed at the heat dissipation location of the battery heat dissipation mechanism 600, and the dustproof sealing component 700 is used to prevent dust from dissipating at the heat dissipation location when the lithium battery 200 is not working.

[0055] The rest of the structure is the same as that of Example 1.

[0056] During the operation, when the lithium battery 200 is working as a whole, the micro motor 701 works, and the micro motor 701 drives the threaded rod 703 to drive the adjustment seat 702 with a surface threaded sleeve to move, and the adjustment seat 702 drives the dustproof plate 706 to move, and the dustproof plate 706 disengages from the heat exhaust hole 68, so that the interior of the battery body 201 is connected with the outside world, and the dustproof plate 706 moves to the top of the sealing plate 607 and is placed, so that the subsequent heat can be discharged through the heat exhaust hole 68. At the same time, when the lithium battery 200 is not working, the micro motor 701 drives the threaded rod 703 to drive the adjustment seat 702 to move, and the adjustment seat 702 drives the dustproof plate 706 to seal the heat exhaust hole 68, thereby achieving sealing in the inner cavity of the battery body 201, reducing the situation where external dust blocks the heat exhaust hole 68, and reducing the cleaning intensity of the worker, thereby achieving effective heat dissipation of the battery 200 when needed, and setting a dustproof setting for the heat dissipation point when not needed to ensure subsequent stable heat dissipation.

[0057] Example 3:

[0058] Reference Figure 1-3 and Figure 6-7 This embodiment is different from the above embodiments in that: the anti-detachment charging mechanism 400 is installed on the top side of the battery shell 100, and the anti-detachment charging mechanism is used to prevent the external charging head from detaching.

[0059] The anti-slip charging mechanism 400 includes a charging connector 401 installed on the top surface of the shell cover 102, a guide frame 402 fixedly installed on the side surface of the charging connector 401, an anti-slip column 403 sliding through the inner cavity of the guide frame 402, an anti-slip component 406 slidingly connected to the end of the anti-slip column 403, and an elastic spring 404 sleeved on the surface of the anti-slip column 403; the cross-section of the anti-slip column 403 is a T-shaped structure, and the right surface of the left end of the anti-slip column 403 is elastically connected to the left side of the guide frame 402 through the elastic spring 404, and a slider 405 with a T-shaped structure is fixedly installed at the end of the anti-slip column 403, and the slider 405 is slidingly connected to the left surface of the anti-slip component 406.

[0060] The anti-slip assembly 406 includes two anti-slip plates 4061, a magnet block 4062 fixedly installed on the side surface of one anti-slip plate 4061 and an iron sheet 4063 correspondingly installed in the slot of the other anti-slip plate 4061; the magnet block 4062 is magnetically connected to the corresponding iron sheet 4063, and the magnet block 4062 is slidingly arranged in the slot; a movable groove corresponding to the sliding block 405 is opened on the left surface of the anti-slip plate 4061.

[0061] The rest of the structure is the same as that of Example 2.

[0062] Operation process: When replenishing the lithium battery 200, the two anti-detachment plates 4061 are opened, and the external charging head is plugged into the charging connector 401. Then, the two anti-detachment plates 4061 are stuck on the surface of the conductive wire and elastically compensated by the elastic spring 404. When the external charging head is pulled by external force, the external charging head and the charging connector 401 are instantly disengaged. Then, under the reaction of the elastic spring 404, the anti-detachment column 403 is pushed to drive the anti-detachment plate 4061 to pull the external charging head to reset again, thereby achieving a stable connection between the charging connector 401 and the external charging head, achieving a good electrical connection, ensuring the stability of subsequent charging, and avoiding re-plugging during the charging process.
