Description

Technical Field

[0001] The present invention relates to the technical field of battery protection, and in particular to a battery protection plate with a high-temperature heat dissipation protection function. Background Art

[0002] Protection board, as the name implies, the lithium protection board is mainly for rechargeable (generally refers to the integrated circuit board that protects the lithium battery positioning bolt. The reason why the lithium battery positioning bolt needs protection is determined by its own characteristics. Since the material of the lithium battery positioning bolt itself determines that it cannot be overcharged, over-discharged, overcurrent, short-circuited and ultra-high temperature charging and discharging, the lithium battery positioning bolt lithium battery assembly will always be accompanied by a protection board with a sampling resistor and a current fuse.

[0003] Most existing battery protection plates are directly installed on the side of the battery pack, first fixed with bolts, and then further fixed with high-temperature tape, making the protection plate body relatively simple in terms of fixing and installation. When the battery protection plate is working normally, it will emit heat. Since the battery protection plate is fixed to the battery pack with high-temperature tape, the heat generated by the battery protection plate is difficult to dissipate, making its heat dissipation effect poor, thereby increasing the heat of the battery protection plate, which in turn has a certain impact on the normal use of the battery protection plate. At the same time, when the battery protection plate fails, the staff needs to disassemble and replace it, which makes the staff more cumbersome when replacing or disassembling the protection plate body, thereby having a certain impact on the use of the protection plate body. To this end, we propose a battery protection plate with high-temperature heat dissipation protection function. Summary of the Invention

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-9The present invention provides a technical solution: a battery protection board 7 with high-temperature heat dissipation protection function, including a fixed frame 2, a battery pack 1 is provided on the back of the fixed frame, a card slot 2 16 at the bottom of the fixed frame 2 is engaged with a card block 12 on the battery pack 1, and a plurality of heat sinks 3 are arranged evenly and equidistantly on the inner bottom wall of the fixed frame 2. The bottoms of the plurality of heat sinks 3 are fixedly connected to the inner bottom wall of the fixed frame 2. Both side walls of the fixed frame 2 are provided with a fixing plate 4, one side of the fixing plate 4 is fixedly connected to the side wall of the fixed frame 2, and a pressure plate 5 is provided on the inner top wall of the fixed frame 2. A reset spring is provided between the pressure plate 5 and the fixed frame 2. 6 is connected, a protective plate body 7 is provided between the pressing plate 5 and the fixing plate 4, the protective plate body 7 is clamped between the pressing plate 5 and the fixing plate 4, the protective plate body 7 is connected to the fixing frame 2 by a positioning bolt 22, and a side wall of the fixing frame 2 close to one end of the pressing plate 5 is provided with a clamping mechanism 8 for limiting the protective plate body 7. When the battery pack 1 needs to be installed with the protective plate body 7, the staff first splices the batteries 9 together through the connecting sleeve 10, and then connects the bottom of the fixing frame 2 with the clamping block 12 on the connecting sleeve 10 through the second clamping slot 16, thereby fixing the fixing frame on the battery pack 1, and then facilitating the installation of the protective plate body 7.

[0027] The battery pack 1 includes a battery 9, and both ends of the battery 9 are provided with a connecting sleeve 10. The connecting sleeve 10 is sleeved on both ends of the battery 9 and limited by a block 13. A card slot 11 is provided on both adjacent sides of the connecting sleeve 10, and a card block 12 adapted to the card slot 11 is provided on the other two adjacent sides of the connecting sleeve 10. The card block 12 is fixedly connected to the side of the connecting sleeve 10 opposite to the card slot 11. The bottom end of the connecting sleeve 10 is provided with a block 13 for limiting the battery 9, and the block 13 is fixedly connected to the four corners of the bottom end of the connecting sleeve 10.

[0028] A through slot 14 is provided at the bottom of the fixing frame 2 for separating the battery 9 and the protective plate 7. The inner bottom wall of the through slot 14 is provided with air guide holes 15 arranged in a rectangular array. Both sides of the bottom of the fixing frame 2 are provided with a second card slot 16 adapted to the card block 12. The battery pack 1 and the protective plate 7 are separated by the through slot 14, thereby facilitating the dissipation of heat from the battery pack 1 and the protective plate 7.

[0029] The edges of both sides of the inner bottom wall of the fixed frame 2 are provided with wind guide plates 17 that are evenly and equidistantly arranged. The wind guide plates 17 are fixedly connected to the edges of both sides of the fixed frame 2. The heat sinks 3 are evenly divided into three groups. Each group of heat sinks 3 is evenly and equidistantly arranged on the inner bottom wall of the fixed frame 2. The three groups of heat sinks 3 are placed on the inner bottom wall of the fixed frame 2 in an inclined form, so that the wind flows to the heat sink 3 through the wind guide plates 17. Through the inclined placement of the heat sink 3, the protection plate body 7 can be better dissipated.

[0030] The clamping mechanism 8 includes a limit plate 81, which is rotatably connected to the fixed frame 2 through a torsion spring shaft. A fixed block 82 is provided on one side of the limit plate 81, and one end of the fixed block 82 is fixedly connected to one side of the limit plate 81. A U-shaped groove 83 is provided on one side of the fixed block 82. The staff pushes the protective plate body 7 into the fixed frame 2 along the fixed plate 4, so that one end of the protective plate body 7 conflicts with the limit plate 81 on the side wall of the fixed frame 2, so that the limit plate 81 rotates through the torsion spring shaft, thereby clamping and fixing the protective plate body 7, which makes it convenient for the staff to fix the protective plate body 7 on the fixed frame 2 through the positioning bolt 22.

[0031] A placement groove 18 is provided at one end of the pressure plate 5 close to the clamping mechanism 8, and the internal sliding connection of the placement groove 18 is connected to a limit block 19. The limit block 19 and the pressure plate 5 are connected by a telescopic spring 20. After the staff limits the protection plate body 7 on the fixed frame 2, the protection plate body 7 is fixed with the positioning bolt 22. When the positioning bolt 22 moves downward to fix the protection plate body 7, the positioning bolt 22 simultaneously pushes the pressure plate 5 to move downward, thereby fixing the protection plate body 7. At the same time, the limit block 19 on one side of the pressure plate 5 is clamped with the U-shaped groove 83 on the clamping mechanism 8, further improving the stability of the protection plate body 7.

[0032] A groove 21 adapted to the clamping mechanism 8 is provided on one end of the side wall of the fixing frame 2 near the pressure plate 5, and the positioning bolt 22 passes through the pressure plate 5, the protection plate body 7 and the fixing plate 4 and is connected to the fixing frame 2. When the protection plate body 7 needs to be disassembled and replaced, it is only necessary to disassemble the positioning bolt 22. When the positioning bolt 22 is disassembled, the pressure plate 5 is lifted by the elastic potential energy of the return spring 6, so that the limit block 19 on one side of the pressure plate 5 is lifted accordingly, thereby driving the clamping mechanism 8 to rotate upward along the torsion spring axis, thereby releasing the limitation and fixation of the protection plate body 7, and making it convenient for the staff to disassemble and replace the protection plate body 7.
