Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for wireless charging power banks, specifically a sliding heat dissipation structure for wireless charging power banks. Background Technology

[0002] A portable power bank, also known as a mobile charger or power bank, is a portable charger that can be carried by the user and stores its own electrical energy. It is primarily used to charge handheld mobile devices and other consumer electronics, especially in situations where an external power source is unavailable. Its main components include a battery for energy storage, circuitry for stabilizing the output voltage, and most portable power banks come with a charger to charge the built-in battery. With technological advancements, wireless charging power banks are becoming increasingly popular. However, during wireless charging, power banks generate a significant amount of heat. If this heat is not dissipated effectively and promptly, the internal temperature of the power bank can become excessively high, affecting battery performance and lifespan, and potentially even causing safety issues.

[0003] Currently, wireless charging power banks on the market use natural heat dissipation through heat dissipation holes or heat dissipation fins, but the heat dissipation efficiency is low and cannot meet the needs of high-power wireless charging.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a sliding heat dissipation structure for wireless charging power banks. Utility Model Content

[0005] The purpose of this invention is to provide a sliding heat dissipation structure for a wireless charging power bank to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sliding heat dissipation structure for a wireless charging power bank, comprising a lower shell and an operation panel. An upper shell is bolted to the upper sides of the lower shell, and a control chip and a temperature sensor are respectively arranged on the right side of the bottom inside the lower shell. A cooling fan is installed on the right side inside the upper shell, and heat dissipation fins are fixed through the left and right sides of the upper shell. A fixing frame is placed in the groove on the right side of the top of the upper shell, and a dustproof net is fixed to the inside of the fixing frame. A plug rod is engaged in the slot on the right side of the fixing frame, and a spring is arranged on the upper right side of the plug rod. The operation panel is located on the lower right side of the plug rod. A battery is also installed inside the upper shell.

[0007] Furthermore, the control chip is electrically connected to the temperature sensor and the cooling fan, with the cooling fan positioned below the dust filter.

[0008] Furthermore, the insertion rod is elastically connected to the upper shell via a spring, and the end of the spring away from the insertion rod is fixedly connected to the upper shell.

[0009] Furthermore, the control panel has a right-angled structure, and the plug rod and the control panel are integrated into one unit.

[0010] Furthermore, a servo motor is installed on the upper left side inside the upper shell, and the output end of the servo motor is connected to a bidirectional lead screw, with a lead screw nut connected to the outside of the bidirectional lead screw.

[0011] Furthermore, a movable block is externally connected to the lead screw nut, and a first scissor bar is hinged to the middle of the movable block via a pin, and a second scissor bar is hinged to the other end of the first scissor bar via a pin.

[0012] Furthermore, a third scissor bar is hinged to the middle of the second scissor bar via a pin, and a fourth scissor bar is hinged to the middle of the first scissor bar via a pin, with the end of the fourth scissor bar away from the third scissor bar being hinged to the upper shell via a pin.

[0013] Furthermore, the end of the second scissor bar away from the first scissor bar is hinged to a slider by a pin, and a sliding rod is inserted inside the slider. The two ends of the sliding rod are fixed with movable brackets, and a sliding cover is provided on the right side of the movable bracket. The edge of the sliding cover is provided with a silicone sealing strip.

[0014] This utility model provides a sliding heat dissipation structure for a wireless charging power bank, which has the following beneficial effects:

[0015] 1. The temperature sensor of this utility model is set at the edge of the wireless charging coil mounting slot at the bottom of the lower shell. It is used to monitor the temperature of the wireless charging area in real time and transmit the data to the control chip. When the temperature is below 40℃, the control chip keeps the cooling fan off and the sliding cover closed. It relies solely on the heat sink for passive heat dissipation and automatically switches the heat dissipation mode based on the temperature threshold. Compared with traditional single fan heat dissipation, it has an energy-saving effect and extends battery life.

[0016] 2. When the temperature reaches 40℃ but is below 55℃, the control chip triggers the servo motor to drive the bidirectional lead screw to rotate. The lead screw nut drives the moving blocks to move in opposite directions. Through the linkage of the first scissor bar, the second scissor bar, the third scissor bar, and the fourth scissor bar, the slider is driven to slide along the slide bar, pushing the moving bracket to open the sliding cover to the first position, exposing part of the dustproof net, and starting the cooling fan to run at low speed, accelerating air convection, carrying away a large amount of heat, improving heat dissipation efficiency, and ensuring that the temperature of the power bank remains stable during operation.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, a sliding heat dissipation structure for a wireless charging power bank includes a lower shell 1 and an operation panel 12. An upper shell 3 is mounted on the upper sides of the lower shell 1 via bolts 2. A control chip 4 and a temperature sensor 5 are respectively installed on the right side of the bottom interior of the lower shell 1. A cooling fan 6 is installed on the right side of the interior of the upper shell 3, and heat dissipation fins 7 are fixedly connected through the left and right sides of the upper shell 3. A fixing frame 8 is placed in a groove on the top right side of the upper shell 3, and a dustproof mesh 9 is fixed inside the fixing frame 8. A slot on the right side of the fixing frame 8 is engaged with... The plug rod 10 has a spring 11 located on its upper right side. The control plate 12 is located on the lower right side of the plug rod 10. The upper shell 3 also has a battery 25 installed inside. The control chip 4 is electrically connected to the temperature sensor 5 and the cooling fan 6. The cooling fan 6 is located below the dust filter 9. The plug rod 10 is elastically connected to the upper shell 3 through the spring 11, and the end of the spring 11 away from the plug rod 10 is fixedly connected to the upper shell 3. The control plate 12 has a right-angle structure, and the plug rod 10 and the control plate 12 are integrated.

[0023] The specific operation is as follows: the temperature sensor 5 is set at the edge of the wireless charging coil mounting slot at the bottom of the lower shell 1 to monitor the temperature of the wireless charging area in real time and transmit the data to the control chip 4. When the temperature is below 40℃, the control chip 4 keeps the cooling fan 6 stopped and the sliding cover 24 closed, relying only on the heat sink 7 for passive heat dissipation. The heat dissipation mode is automatically switched according to the temperature threshold. Compared with the traditional single fan heat dissipation, it has the effect of energy saving and extends the battery 25 life.

[0024] like Figure 2 As shown, a servo motor 13 is installed on the upper left side inside the upper shell 3, and the output end of the servo motor 13 is connected to a bidirectional lead screw 14. A lead screw nut 15 is connected to the outside of the bidirectional lead screw 14, and a moving block 16 is connected to the outside of the lead screw nut 15. A first scissor bar 17 is hinged to the middle of the moving block 16 via a pin. A second scissor bar 18 is hinged to the other end of the first scissor bar 17 via a pin. A third scissor bar 19 is hinged to the middle of the second scissor bar 18 via a pin. The middle part of the first scissor bar 17 is hinged to the fourth scissor bar 20 by a pin, and the end of the fourth scissor bar 20 away from the third scissor bar 19 is hinged to the upper shell 3 by a pin. The end of the second scissor bar 18 away from the first scissor bar 17 is hinged to the slider 21 by a pin, and a slide rod 22 is provided inside the slider 21. The two ends of the slide rod 22 are fixed to the movable bracket 23, and a sliding cover 24 is provided on the right side of the movable bracket 23. A silicone sealing strip 26 is provided on the edge of the sliding cover 24.

[0025] The specific operation is as follows: when the temperature reaches 40℃ but is below 55℃, the control chip 4 triggers the servo motor 13 to drive the bidirectional lead screw 14 to rotate. The lead screw nut 15 drives the moving block 16 to move in opposite directions. Through the linkage of the first scissor bar 17, the second scissor bar 18, the third scissor bar 19, and the fourth scissor bar 20, the slider 21 is driven to slide along the slide bar 22, pushing the moving bracket 23 to open the sliding cover 24 to the first position, exposing part of the dustproof net 9, and starting the cooling fan 6 to run at low speed, accelerating air convection, carrying away a large amount of heat, improving heat dissipation efficiency, and ensuring that the temperature of the power bank remains stable during operation.

[0026] In summary, the sliding heat dissipation structure of this wireless charging power bank allows for the following operation: First, the power bank is installed inside the housing consisting of the lower shell 1 and the upper shell 3, ensuring that the wireless charging coil aligns with the wireless charging coil mounting slot at the bottom of the lower shell 1. The temperature sensor 5 monitors the temperature at the wireless charging coil mounting slot at the bottom of the lower shell 1 in real time and transmits the data to the control chip 4. When the temperature of the wireless charging area is below 40°C, it indicates that the power bank is in a low-load working state and generates less heat. At this time, the control chip 4 keeps the cooling fan 6 off and controls the servo motor 13 inside the upper shell 3 to remain inactive, keeping the sliding cover 24 closed. In this state, the power bank relies solely on the heat dissipation fins 7 on the left and right sides of the upper shell 3 for passive natural heat dissipation, releasing the small amount of heat generated into the surrounding environment. Simultaneously, because the sliding cover 24 is closed, the silicone sealing strip 26 on its edge tightly adheres to the upper shell 3, providing good dustproof and waterproof protection, reducing the entry of external dust into the device, lowering energy consumption, and extending the battery 25's lifespan.

[0027] When the temperature sensor 5 detects a temperature of 40℃ but below 55℃, the control chip 4 activates, sending start commands to the cooling fan 6 and servo motor 13. This causes the cooling fan 6 to operate at low speed, accelerating airflow within the device and creating better convection conditions for heat dissipation. Simultaneously, the servo motor 13 drives the bidirectional lead screw 14 to rotate, causing the lead screw nut 15 to move axially along the bidirectional lead screw 14. This, in turn, drives the moving blocks 16 to move in opposite directions. The first scissor bar 17, hinged in the middle of the moving blocks 16, rotates under the influence of the moving blocks 16. The second scissor bar 18, the third scissor bar 19, and the fourth scissor bar 20 are driven by the hinged pins. Under the series of linkages, the slider 21, which is hinged to the second scissor bar 18, slides along the slide bar 22. The slider 21 drives the moving bracket 23 to move, and finally pushes the sliding cover 24 to open to the first position, exposing part of the dustproof mesh 9. At this time, air can enter the interior of the upper shell 3 through the exposed dustproof mesh 9. Under the action of the cooling fan 6, a large amount of heat is carried away, significantly improving the heat dissipation efficiency and ensuring that the temperature of the power bank remains stable under medium load operation.

[0028] When the temperature reaches or exceeds 55℃, the control chip 4 triggers the servo motor 13 to drive the sliding cover 24 to open completely, and the cooling fan 6 runs at high speed to avoid overheating. The fixed heat dissipation hole design is replaced by adjusting the opening of the sliding cover 24, which greatly improves the heat dissipation efficiency. The temperature sensor 5 adopts an NTC thermistor (model NTCS0603E3103JLT), and the heat dissipation fins 7 are made of aluminum alloy 6063 with a thermal conductivity coefficient ≥180W / (m·K).

[0029] During daily use, the dustproof net 9 will trap a large amount of dust. Since the insertion rod 10 is elastically connected to the upper shell 3 through the spring 11, and the insertion rod 10 and the operating plate 12 are integrated, when it is necessary to clean the dustproof net 9, the operating plate 12 can be pulled outward to move the insertion rod 10 and compress the spring 11, so that the insertion rod 10 is disengaged from the slot on the right side of the fixing frame 8. At this time, the fixing frame 8 can be removed from the groove, which is convenient for cleaning the dustproof net 9. After cleaning, the operating plate 12 is pulled outward to place the fixing frame 8 back into the groove on the top right side of the upper shell 3. The operating plate 12 is released, the spring 11 returns to its deformation, and pushes the insertion rod 10 back into the slot of the fixing frame 8, so as to realize the quick installation and fixation of the fixing frame 8 and the dustproof net 9, and ensure the continuous effectiveness of the dustproof function.
