Description

Technical Field

[0001] This utility model relates to the field of lithium battery protection board technology, specifically to a lithium battery protection board with high-efficiency heat dissipation. Background Technology

[0002] Lithium-ion battery protection boards are key components ensuring the safe operation of lithium-ion batteries, providing protection against overcharge, over-discharge, short circuits, and overcurrent. With the increasing prevalence of electric vehicles and mobile devices, the safety performance requirements for lithium-ion batteries are becoming increasingly stringent, making their safety testing particularly important as a crucial component for ensuring the safety of lithium-ion batteries.

[0003] Most existing battery protection boards dissipate the heat generated by the battery through heat transfer, which is inefficient. Furthermore, relying on airflow for cooling leads to dust accumulation inside the board over time, further reducing heat dissipation efficiency and failing to meet current requirements. Therefore, this application provides a lithium battery protection board with high-efficiency heat dissipation. Utility Model Content

[0007] A cooling module is inserted into the outside of the base plate and the top plate. The cooling module includes a cooling fan, a bottom groove, and a top lug.

[0008] An integrated frame is detachably connected inside a composite panel. The integrated frame includes a battery compartment and a connecting groove. The battery compartment is formed by vertically connecting the internal plates of the integrated frame. The edges of the integrated frame plates are tightly fitted to the inner wall of the composite panel.

[0009] Furthermore, electrode contacts are fixedly connected inside both the bottom plate and the top plate. There are multiple sets of electrode contacts that are vertically aligned. Mounting grooves are provided inside both the bottom plate and the top plate. There are multiple sets of mounting grooves that are vertically aligned.

[0010] Furthermore, both the bottom plate and the top plate have assembly grooves on their exteriors. The assembly groove on the exterior of the bottom plate has a bottom slope, and the assembly groove on the exterior of the top plate has a top slope.

[0011] Furthermore, there are two sets of bottom grooves symmetrically distributed outside the cooling module, two sets of top ears symmetrically distributed on the opposite side of the cooling module, and the cooling fan is located at the center of the cooling module.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] Please see Figures 1 to 5 As shown, the present invention provides a high-efficiency heat dissipation lithium battery protection board, including a main frame 1. The main frame 1 includes a bottom plate 101, a top plate 102, and a combined plate 103. Both the bottom plate 101 and the top plate 102 have fitting grooves 104 on their exteriors, and sealing rings 105 are attached inside the fitting grooves 104. The invention also includes:

[0028] Cooling module 2 is plugged into the outside of the base plate 101 and the top plate 102. Cooling module 2 includes a cooling fan 201, a bottom groove 202 and a top lug 203.

[0029] The integrated frame 3 is detachably connected inside the combined plate 103. The integrated frame 3 includes a battery compartment 301 and a connecting groove 302. The battery compartment 301 is formed by vertical connection of the internal plates of the integrated frame 3. The edges of the plates of the integrated frame 3 are tightly attached to the inner wall of the combined plate 103.

[0030] Specifically, when assembling the device, the combination plate 103 is placed inside the fitting groove 104 outside the bottom plate 101 and the top plate 102, respectively. Then, the sleeve 111 is inserted into the mounting groove 107 and through the joint sleeve 113. Then, the bolt 112 is screwed into the sleeve 111. The bottom plate 101, the top plate 102 and the combination plate 103 are tightly assembled by the sleeve 111 and the bolt 112. During this process, it is necessary to ensure that the electrodes at both ends of the battery body 4 are in contact with the electrode contacts 106, thereby completing the assembly of the device.

[0031] Example 2

[0032] Please see Figures 1 to 5 As shown in Embodiment 1, electrode contacts 106 are fixedly connected inside both the base plate 101 and the top plate 102. There are multiple sets of electrode contacts 106 that are vertically corresponding. Mounting grooves 107 are provided inside both the base plate 101 and the top plate 102. There are multiple sets of mounting grooves 107 that are vertically corresponding. Assembly grooves 108 are provided on the outside of both the base plate 101 and the top plate 102. The assembly groove 108 on the outside of the base plate 101 has a bottom slope 109, and the assembly groove 108 on the outside of the top plate 102 has a top slope 110. There are two sets of bottom grooves 202 that are symmetrically distributed on the outside of the cooling module 2. There are two sets of top ears 203 that are symmetrically distributed on the opposite side of the cooling module 2. The cooling fan 201 is located at the center of the cooling module 2.

[0033] By making the above settings, the battery generates relatively little heat during normal operation. Natural heat dissipation through the base plate 101, top plate 102, and combined plate 103 is sufficient to ensure normal operation. When excessive heat is generated during device operation, the cooling fan 201 is turned on to pump outside air into the space enclosed by the combined plate 103. The air passes through the connecting groove 302 outside the battery compartment 301, carrying the heat around each battery with the flowing air, and finally continuously exhausting it through the ventilation groove 114 on the side away from the cooling module 2, thereby ensuring that the internal temperature of the device remains within a safe range.

[0034] Example 3

[0035] Please see Figures 1 to 5 As shown in Embodiment 2, the bottom groove 202 is fitted and connected to the bottom slope 109, the top ear 203 is fitted and connected to the top slope 110, the cooling fan 201 is connected to the internal space of the combination plate 103, the joint sleeve 113 is fixedly connected to the connection of each plate of the combination plate 103, the plate of the combination plate 103 and the cooling module 2 are provided with ventilation slots 114 on the outside of the plate, the plate of the combination plate 103 away from the cooling module 2 is fixedly connected to the closed end 115, the mounting slots 107 are movably connected to the sleeve 111, the sleeve 111 is threaded with a bolt 112, the sleeve 111 and the bolt 112 tightly connect the bottom plate 101, the top plate 102 and the combination plate 103 in the vertical direction, and the battery body 4 is movably connected inside the battery compartment 301.

[0036] By making the above settings, after the device has been used for a long time, the bottom plate 101 and the top plate 102 can be separated by separating the sleeve 111 and the bolt 112, and then the closed end 115 of the outside of the combined plate 103 can be separated to unfold and clean the combined plate 103, ensuring that the device cleaning will not produce dead corners.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
