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 creative work are within the scope of protection of the present invention.

[0028] Specific examples are given below.

[0029] See also Figure 1 - Figure 5 The present invention provides a graphene battery pack heat dissipation device, comprising a graphene battery pack body 1 and a mounting assembly, wherein a connecting plate 11 is fixedly connected to the bottom of the outer wall of the graphene battery pack body 1; a protective box 12 is arranged on the top of the outer wall of the connecting plate 11; a mounting assembly is arranged on the side wall of the protective box 12; the side wall of the mounting assembly is connected to the connecting plate 11; a servo motor 13 is fixedly connected to the side wall of the protective box 12; an auxiliary connecting rod 103 is fixedly connected to the output end of the servo motor 13; the auxiliary connecting rod 103 is rotatably connected inside the protective box 12; a first fan blade 15 is fixedly connected to the outer wall of the auxiliary connecting rod 103; a plurality of ventilation holes 14 are opened on the side wall of the protective box 12; the auxiliary The outer wall of the auxiliary connecting rod 103 is fixedly connected to the first synchronous wheel 16; the auxiliary connecting rod 103 is set as a pair; the side wall of another auxiliary connecting rod 103 is fixedly connected to the second synchronous wheel 17; the first synchronous wheel 16 is transmission connected to the second synchronous wheel 17 through a synchronous belt 18; the outer wall of the auxiliary connecting rod 103 is fixedly connected to the first gear 19; the inner wall of the protection box 12 is rotatably connected to a pair of first connecting columns 10; the outer wall of the first connecting column 10 is fixedly connected to the second gear 101, and the second gear 101 is meshed with the first gear 19; the outer wall of the first connecting column 10 is fixedly connected to the second fan blade 102; the second fan blade 102 has an opposite blade angle to the first fan blade 15. First, install the protection box 12 above the connecting plate 11. When the graphene battery pack body 1 needs to be cooled, start the servo motor 13. The servo motor 13 will drive the auxiliary connecting rod 103 to rotate. At this time, the first synchronous wheel 16 will rotate. The first synchronous wheel 16 drives the second synchronous wheel 17 to rotate through the synchronous belt 18, so that the two auxiliary connecting rods 103 rotate in the same direction. When the auxiliary connecting rod 103 rotates, the first fan blade 15 will follow the rotation to suck the wind from the inside of the graphene battery pack body 1 to the direction of the servo motor 13. When the auxiliary connecting rod 103 rotates, the first gear 19 will also follow the rotation, and the second gear 101 meshing with the first gear 19 will rotate in the opposite direction to rotate the second fan blade 102. The second fan blade 102 blows the air from the first gear 19 to the first fan blade 15. By setting the auxiliary connecting rod 103 and the servo motor 13, the device can drive multiple fans to rotate at the same time with one motor. The synchronous operation of multiple fans can generate a larger airflow and enhance the heat dissipation effect. The number of motors can reduce the failure rate of the system.

[0030] Further, such as Figure 1 , Figure 2 and Figure 3As shown, the side wall of the protection box 12 is fixedly connected to the filter plate 2; the second connecting column 21 is rotatably connected inside the filter plate 2; the inner wall of the protection box 12 is fixedly connected to the fixing plate 25; the fixing plate 25 is rotatably connected to the second connecting column 21; the outer wall of the second connecting column 21 is fixedly connected to a brush plate 22; the side wall of the brush plate 22 is fixedly connected to a plurality of bristles 23; the bristles 23 are in contact with the filter plate 2; the outer wall of the second connecting column 21 is fixedly connected to an auxiliary fan blade 24. When the device is working, the air inside the protection box 12 will flow to one side, and the fast-flowing air will blow the auxiliary fan blades 24, which will rotate, thereby causing the second connecting column 21 to rotate. At this time, the brush plate 22 and the bristles 23 will rotate along, and the bristles 23 will clean the dust attached to the side wall of the second connecting column 21. By setting the auxiliary fan blades 24 and bristles 23, the filter plate 2 can be cleaned while the device is working, thereby reducing the situation where the ventilation capacity of the device becomes poor due to dust accumulation and blockage when the device is used for a long time.

[0031] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, the inner side wall of the protection box 12 is fixedly connected to one end of a plurality of springs 3; the other end of the spring 3 is fixedly connected to a pressing plate 31; a heat conducting plate 32 is installed at the bottom of the outer side wall of the pressing plate 31; the pressing plate 31 and the heat conducting plate 32 can be slightly bent; a plurality of fins 33 are fixedly connected to the top of the outer side wall of the pressing plate 31; holes are provided on the protection box 12, and the holes are adapted to allow the fins 33 to pass through so that the fins 33 are partially exposed to the outside of the protection box 12. When the device is working, the spring 3 will push the pressing plate 31 and the heat conducting plate 32 to contact the graphene battery pack body 1. At this time, the heat conducting plate 32 will transfer the heat upward, and the heat will be dissipated outward through the spring 3. When the air flows, the air will take away the heat on the surface of the fin 33. By setting the spring 3 and the pressing plate 31, the heat generated by the graphene battery pack body 1 can have an additional dissipation position, thereby increasing the overall heat dissipation effect of the device.

[0032] Further, such as Figure 5As shown, a plurality of sleeves 4 are fixedly connected to the top of the outer wall of the pressing plate 31; a plurality of threaded rods 41 are threadedly connected to the inside of the protection box 12; a fixed disk 42 is fixedly connected to the bottom of the outer wall of the threaded rod 41; the fixed disk 42 cannot be separated from the sleeve 4; a turntable 43 is installed on the top of the threaded rod 41; and the threaded rod 41 is rotatably connected to the inner wall of the sleeve 4. When the device is working, the turntable 43 is rotated to rotate the threaded rod 41, at which time the position of the fixed disk 42 will change, and the fixed disk 42 will move upward. When the fixed disk 42 moves upward, it will drive the sleeve 4 to move upward, thereby moving the position of the pressing plate 31 upward. By setting the threaded rod 41 and the sleeve 4, the maximum position of the pressing plate 31 can be controlled, so as to reduce the deformation of the heat conducting plate 32 caused by excessive extrusion and increase the service life of the heat conducting plate 32.

[0033] Further, such as Figure 5 As shown, a cross connection groove 5 is provided on the top of the threaded rod 41; a cross plate 51 is fixedly connected to the bottom of the outer wall of the turntable 43; the cross plate 51 is in sliding contact with the cross connection groove 5. When the equipment is working, when the staff needs to rotate the turntable 43, the cross plate 51 is inserted into the cross connection groove 5. At this time, when the turntable 43 is rotated, the threaded rod 41 will rotate with it. After the rotation is completed, the cross plate 51 can be separated from the cross connection groove 5. At this time, the threaded rod 41 is difficult to rotate. By setting the cross connection groove 5 and the cross plate 51, the connection between the turntable 43 and the threaded rod 41 can be changed to plug-in, which is convenient for protecting the adjusted equipment and reducing the probability of secondary adjustment due to accidental touch.

[0034] Further, such as Figure 1 As shown, the side wall of the protection box 12 is fixedly connected with a pair of limit bars 6; the side wall of the limit bar 6 is slidably contacted with a sealing plate 61. When the device is working, the sealing plate 61 can be slid into the limit bar 6 in cold weather to fill and seal the hole in the side wall of the protection box 12. By setting the limit bar 6 and the sealing plate 61, the protection of the internal temperature of the protection box 12 can be increased, and the influence of low temperature on the graphene battery pack body 1 can be reduced.

[0035] Further, such as Figure 1 As shown, the installation assembly includes a limit plate 7 and a bolt 71; a plurality of limit plates 7 are fixedly connected to the side wall of the protection box 12; and the limit plates 7 are bolted to the connecting plate 11 by bolts 71. When the device is working, the limit plate 7 can be bolted to the top of the connecting plate 11, so that the protection box 12 can stay stably above the connecting plate 11. The limit plates 7 and the bolts 71 are provided to increase the stability of the protection box 12 when working.

[0036] Further, such as Figure 5As shown, the side wall of the threaded rod 41 is fixedly connected with a fixing collar 8. When the equipment is working, the staff will rotate the turntable 43 to rotate the threaded rod 41, and the fixing collar 8 can limit the maximum range of movement of the threaded rod 41. By setting the fixing collar 8, the situation that the threaded rod 41 is separated from the equipment due to excessive rotation is reduced, and the stability of the equipment during operation is increased.

[0037] Further, such as Figure 5 As shown, the side wall of the rotating disk 43 is provided with a plurality of scraping grooves 9. When the equipment is working, the scraping grooves 9 can scrape off the sweat and other liquids attached to the palms of the staff, and the scraping grooves 9 are provided to reduce the probability of slipping when the staff rotates the rotating disk 43.

[0038] Working principle: first install the protection box 12 on the connecting plate 11. When the graphene battery pack body 1 needs to be cooled, start the servo motor 13. The servo motor 13 will drive the auxiliary connecting rod 103 to rotate. At this time, the first synchronous wheel 16 will rotate. The first synchronous wheel 16 drives the second synchronous wheel 17 to rotate through the synchronous belt 18, so that the two auxiliary connecting rods 103 rotate in the same direction. When the auxiliary connecting rod 103 rotates, the first fan blade 15 will rotate with it, and the wind will be sucked from the inside of the graphene battery pack body 1 to the direction of the servo motor 13. When the auxiliary connecting rod 103 rotates, the first gear 19 will also rotate with it, and the second gear 101 meshing with the first gear 19 will rotate in the opposite direction to rotate the second fan blade 102. The second fan blade 102 blows the air from the first gear 19 to the first fan blade 15. Through the auxiliary connecting rod 103 and the servo motor 13, the device can drive multiple fans to rotate at the same time with one motor. The synchronous operation of multiple fans can generate a larger airflow and enhance the heat dissipation effect. The number of motors can reduce the failure rate of the system. When the device is working, the air inside the protection box 12 will flow to one side, and the fast-flowing air will blow the auxiliary fan blade 24, and the auxiliary fan blade 24 will rotate, thereby rotating the second connecting column 21. At this time, the brush plate 22 and the bristles 23 will rotate with it, and the bristles 23 will clean the dust attached to the side wall of the second connecting column 21. Through the auxiliary fan blades 24 and the bristles 23, it can be set While the equipment is working, the filter plate 2 is cleaned to reduce the situation where the ventilation capacity of the equipment becomes poor due to dust accumulation and clogging when the equipment is used for a long time. When the equipment is working, the spring 3 will push the pressing plate 31 and the heat conducting plate 32 to contact the graphene battery pack body 1. At this time, the heat conducting plate 32 will transfer the heat upward, and the heat will dissipate outward through the spring 3. When the air flows, the air will take away the heat on the surface of the fin 33. By setting the spring 3 and the pressing plate 31, the heat generated by the graphene battery pack body 1 can have an additional dissipation position, thereby increasing the overall heat dissipation effect of the equipment. When the equipment is working, the turntable 43 is rotated to rotate the threaded rod 41. At this time, the position of the fixed plate 42 will change, and the fixed plate 42 will move up. When the fixed plate 42 moves up It will drive the sleeve 4 to move upward, and then the position of the pressing plate 31 will move upward. Through the provision of the threaded rod 41 and the sleeve 4, the maximum position of the pressing plate 31 can be controlled, thereby reducing the deformation of the heat conducting plate 32 caused by excessive extrusion and increasing the service life of the heat conducting plate 32. When the equipment is working, when the staff needs to rotate the turntable 43, the cross plate 51 is inserted into the cross connecting groove 5. At this time, when the turntable 43 is rotated, the threaded rod 41 will rotate with it. After the rotation is completed, the cross plate 51 can be separated from the cross connecting groove 5. At this time, the threaded rod 41 is difficult to be rotated. Through the provision of the cross connecting groove 5 and the cross plate 51, the connection mode between the turntable 43 and the threaded rod 41 can be changed to plug-in, which is convenient for protecting the adjusted equipment.The probability of secondary adjustment due to accidental touch is reduced. When the equipment is working, when the weather is cold, the sealing plate 61 can be slid into the limit bar 6 to fill and seal the hole on the side wall of the protection box 12. By setting the limit bar 6 and the sealing plate 61, the protection of the internal temperature of the protection box 12 can be increased, and the influence of low temperature on the graphene battery pack body 1 can be reduced. When the equipment is working, the limit plate 7 can be bolted to the top of the connecting plate 11, so that the protection box 12 can stay stably above the connecting plate 11. The limit plate 7 and the bolt 71 are set to increase the stability of the protection box 12 when working. When the equipment is working, the staff will rotate the turntable 43 to rotate the threaded rod 41. The fixed collar 8 can limit the maximum range of movement of the threaded rod 41. The fixed collar 8 is set to reduce the situation that the threaded rod 41 is separated from the equipment due to excessive rotation, and the stability of the equipment when working is increased. When the equipment is working, the scraper groove 9 can scrape off the sweat and other liquids attached to the palm of the staff. The scraper groove 9 is set to reduce the probability of slipping when the staff rotates the turntable 43. ,
