Description

A wireless charging device with temperature control Technical Field

[0001] This utility model relates to the field of wireless charging device technology, and more specifically, to a wireless charging device with temperature control. Background Technology

[0002] As mobile phones become more powerful and their configurations become more advanced, when using functions such as navigation, live streaming, playing mobile games, recording videos, and wireless charging, the internal components of mobile phones and other electronic devices, such as the CPU and battery cells, will generate heat, even to the point of becoming extremely hot in high ambient temperatures. This can cause the phone to run slowly or lag, affecting the user experience. As a result, various heat sinks or cooling devices have begun to appear on the market.

[0003] Currently, market coolers mainly fall into two categories: one type uses a fan to blow heat, typically onto the back of the phone. These devices contain an electronic control unit and motor that generate additional heat, transferring it to the back of the phone. The other type uses a more expensive semiconductor cooling module. This type cools the phone or other electronic device by placing the semiconductor cooler in close contact with its back. However, semiconductor modules are expensive, require significant power consumption, and because the back of these devices is typically made of glass or other materials with poor thermal conductivity, the cooling speed is slow, the cooling effect is limited, and the cost is high. In light of these issues, it is necessary to propose a wireless charging device with temperature control to at least partially address the problems existing in current technologies.

The temperature adjustment unit includes a temperature control electronic unit and several cooling plates. The temperature control electronic unit is electrically connected to the wireless charging control unit.

[0012] According to an embodiment of the present invention, the wireless charging control unit further includes a charging detection module.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0031] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] As shown in Figures 1-7, this utility model provides a wireless charging device with temperature control, including: a charging device body 100, wherein the charging device body 100 includes a front shell 1, a bottom shell 2, a temperature adjustment module 3, and a wireless charging module 4. The front shell 1 is mounted on the bottom shell 2 and located on the front side, and there is a cavity 10 between the front shell 1 and the bottom shell 2. The temperature adjustment module 3 and the wireless charging module 4 are installed in the cavity 10, and the temperature adjustment module 3 and the wireless charging module 4 are electrically connected. The front shell 1 has a charging area surface 101 corresponding to the wireless charging module 4 and a magnetic attraction area surface 102. The charging area surface 101 is located within the magnetic attraction area surface 102. The charging area surface 101 has a vent 103, and the magnetic attraction area surface 102 has a vent 11. The bottom shell 2 has multiple air outlets 21.

[0033] Therefore, when using this wireless charging device, the phone is placed on the housing 1, and the magnetic surface 102 can hold the phone in place, while the wireless charging module 4 wirelessly charges the phone. The wireless charging module 4 generates heat when it is working. After the temperature regulation module 3 is activated, the air inside the cavity 10 is first exhausted through the multiple air outlets 21 of the bottom housing 2. Then, the cooler air from the outside flows through the ventilation component 11 on the magnetic surface 102 towards the center of the charging surface 101. During this process, the cooler air flows over the back of the phone, which can also carry away the heat from the phone. The cooler air enters the cavity 10 through the ventilation component 11 and the air guide 103. After passing through the temperature regulation module 3, the air is exhausted from the cavity 10. At this time, the air also carries away the heat from the wireless charging module 4, which lowers the temperature inside the charging device body 100. This avoids the problem in the prior art where the heat generated by the internal components is blown to the back of the phone, causing the phone to get even hotter.

[0034] By designing the above structure, the main body 100 of this charging device aims to improve or solve the problem of slow cooling speed and limited cooling effect of current coolers. By drawing air into the cooler from the back of mobile phones and other electronic devices, the airflow, which is at a lower ambient temperature than the mobile phones and other electronic devices, carries away heat through contact with the back of the mobile phones and other electronic devices. This avoids the heat generated inside the charging device main body 100 being conducted to the mobile phones and other electronic devices, thereby achieving a cooling effect and facilitating charging.

[0035] Exemplary face shell

[0036] Furthermore, some embodiments of this utility model provide a specific structure for the aforementioned housing 1. Here, the housing 1 can be circular, square, or elliptical. Here, a circular housing 1 is used as an example. The charging area 101 is located within the magnetic attraction area 102, and the height of the charging area 101 is lower than the height of the magnetic attraction area 102. The air guide component 11 includes multiple first ventilation slots 110, which penetrate the magnetic attraction area 102. Therefore, when the internal temperature regulation module 3 is activated, external air enters the charging area 101 through the multiple first ventilation slots 110. This allows the air to carry away the heat from the phone, effectively reducing the phone's temperature and ensuring smoother phone operation or preventing the wireless charging power from decreasing due to overheating. Meanwhile, since the height of the charging area 101 is lower than the height of the magnetic area 102, the cold air entering the charging area 101 through the first ventilation slot 110 can make maximum contact with the back of the phone and the charging area 101, thereby maximizing the removal of heat from the phone and the charging area 101 to achieve the best cooling effect.

[0037] Exemplary ventilation components

[0038] Furthermore, some embodiments of this utility model provide a specific structure of the ventilation component 11 described above. Here, the ventilation component 11 of this structure also includes a plurality of protrusions 111. The plurality of protrusions 111 are evenly distributed in the charging area surface 101 at intervals. The height of the protrusions 111 is lower than the height of the magnetic attraction area surface 102 or the height of the protrusions 111 is the same as the height of the magnetic attraction area surface 102. The plurality of protrusions form a plurality of concentric air guide rings 12 and a plurality of divergent air guide grooves 13 on the charging area surface 101, and the air guide rings 12 and the divergent air guide grooves 13 are interconnected. The second ventilation slot 13 extends from the center outwards, making the air guide ring slot 12 and the second ventilation slot 13 interconnected. Therefore, when the mobile phone is attached to the surface housing 1, air enters the air guide ring slot 12 and the second ventilation slot 13 between the mobile phone and the surface charging area 101. The air guide ring slot 12 and the second ventilation slot 13 can form a "maze" structure, which can prolong the airflow time. As a result, the air can contact the back of the mobile phone for a longer time, and better carry away the heat of the mobile phone into the cavity 10. This realizes the heat dissipation function of the charging device body 100 for the mobile phone, and avoids the heat generated inside the charging device body 100 from being conducted to the mobile phone and other electronic devices, thereby achieving a cooling effect and facilitating charging.

[0039] Exemplary fixing mechanism

[0040] As shown in Figure 9, in some embodiments of this utility model, a fixing mechanism 20 is further installed on the rear side of the bottom shell 2. Here, the fixing mechanism 20 includes a soft pad 201, a ball head seat 202, and a nut sleeve 203. The soft pad 201 is installed inside the ball head seat 202. The fixing mechanism 20 is connected to the rear side of the bottom shell 2 by screws 204. The nut sleeve 203 is installed on the ball head seat 202. By rotating the nut sleeve 203, the ball head seat 202 can be tightened, and the ball head seat 202 can be fixed on the ball head mechanism (not shown), which is convenient for carrying and use. At the same time, due to the friction of the soft pad, the ball head mechanism (not shown) can rotate with the fixing mechanism 20, and can also ensure a tight connection and support the fixing mechanism 20.

[0041] Exemplary wireless charging module

[0042] Furthermore, some embodiments of this utility model provide a specific structure of the wireless charging module 4 described above. Here, the wireless charging module 4 of this structure includes a fixed base 41, a wireless charging control unit 42, and a wireless charging coil 43. The wireless charging control unit 42 is installed on the rear side of the fixed base 41, while the wireless charging coil 43 is installed on the front side of the fixed base 41. The wireless charging control unit 42 and the wireless charging coil 43 are electrically connected, and the wireless charging control unit 42 charges the mobile phone through the wireless charging coil 43.

[0043] Understandably, the wireless charging control unit 42 is mounted on a PCB board (not shown), which in turn can be mounted on the mounting base 41.

[0044] Exemplary magnet component

[0045] Furthermore, some embodiments of this utility model provide a specific structure of the magnet assembly 5. The magnet assembly 5 is installed inside the cavity 10 and corresponds to the magnetic attraction area 102. Therefore, when the mobile phone is placed on the magnetic attraction area 102, the mobile phone can be magnetically fixed by the internal magnet assembly 5.

[0046] Specifically, the magnet assembly 5 of the above structure includes multiple magnet blocks 51 and an inner base 52. The inner base 52 is installed on the outer periphery of the fixed base 41, and the multiple magnet blocks 51 are installed at intervals on the outer periphery of the inner base 52. The wireless charging coil 43 is located in the middle of the multiple magnet blocks 51, so as to magnetically fix the mobile phone. A charging interface 44 is also provided on the outer periphery of the wireless charging control unit 42. Correspondingly, the bottom housing 2 has an opening 22 that cooperates with the charging interface 44. In this way, the power adapter can be connected to the charging interface 44 to supply power to the wireless charging control unit 42, and then wireless charging can be performed through the wireless charging coil 43.

[0047] Exemplary temperature control module

[0048] As shown in Figures 1 and 5-6, further embodiments of this utility model provide a specific structure for the temperature regulation module 3. This temperature regulation module 3 includes a heat sink 31 and a temperature regulation unit 32. The temperature regulation unit 32 includes a temperature control electronic unit and several cooling plates. The temperature control electronic unit is electrically connected to the wireless charging control unit 42. The cooling plates 33 are installed on the front side of the heat sink 31 and electrically connected to the temperature control electronic unit. The heat sink 31 is installed on the rear side of the wireless charging coil 43 or on the periphery of the wireless charging coil 43. The heat sink 31 has multiple heat sinks 311. Therefore, when the cooling plates start working, the heat on the back of the cooling plates can be dissipated outwards through the heat sink 31 and the multiple heat sinks 311, which helps the cooling plates to cool more effectively. When the cooling plates are cooling, they can be closer to the wireless charging coil 43, which further helps to reduce the temperature of the wireless charging coil 43 during charging, avoiding a reduction in wireless charging power due to heat generation.

[0049] As shown in Figures 7 and 8, further, when the housing 1 is elliptical, the housing 1 also has an auxiliary cooling area 104. The auxiliary cooling area 104 is located outside the magnetic attraction area 102. At this time, the temperature adjustment module 3 is located on the periphery of the wireless charging coil 43. The low-temperature surface of the cooling chip 33 is in contact with the inner surface of the auxiliary cooling area 104 to achieve a better cooling effect. In this way, the cooling chip 33 is located outside the wireless charging coil 43 and close to the housing. The high-temperature surface of the cooling chip 33 is in contact with the heat sink 31 to achieve a better heat dissipation effect. In this way, the air entering the ventilation component can be cooled down in advance when passing through the auxiliary cooling area 104, thereby reducing the temperature of the mobile phone and the charging device. The cooling chip 33 can also cool the air entering the cavity, which can further cool the inside of the cavity and also help reduce the temperature of the wireless charging coil 43 when it is charging, avoiding the wireless charging power being reduced due to heat generation.

[0050] In addition, cooling the cooling element 33 can also cool the surrounding air. Therefore, the surrounding air drawn into the charging device body 100 will be cooled into cold air, flowing over the back of the phone, the front casing 1 of the charging device body 100, and then into the internal cavity. Overall, by drawing air into the interior, the heat generated by the charging device body 100 can be minimized from being output to the front casing and the back of the phone. At the same time, because the air flows over most of the front casing, a better cooling effect can be achieved.

[0051] Furthermore, the aforementioned auxiliary cooling zone 104 can be made of aluminum alloy or zinc alloy, which is more conducive to the cooling effect of the shell 1.

[0052] Furthermore, the aforementioned temperature regulation unit 32 can be configured as a fan. Therefore, the fan is mounted on the heat sink 31 via the inner seat 321, and the fan is electrically connected to the wireless charging control unit 42. Thus, when the fan is started, it blows air, thereby expelling heat from the cavity 10 to the outside.

[0053] Furthermore, the wireless charging module 4 also includes a charging detection module (not shown). When the charging detection module detects that the wireless charging coil 43 has started to work or the temperature exceeds the preset temperature range, the charging detection module sends a signal to the temperature regulation module 3, so that the temperature regulation module 3 can start to work to drive airflow and reduce the temperature.

[0054] Furthermore, the temperature regulation unit 32 also includes a voice control module, an NFC module, a FindMy module, and a sensing module. These modules are electrically connected to the temperature control electronic unit, enabling various functions and facilitating user operation. Additionally, the temperature regulation unit 32 includes a temperature setting module for setting a preset temperature to start or stop the temperature regulation module 3. When the temperature exceeds or falls below the preset value, the temperature setting module sends a signal to the temperature regulation module 3 to begin operation. This structural design significantly increases the practicality and application range of the temperature-controlled wireless charging device, making it convenient for users in various scenarios.

[0055] It is understood that all of the above modules are well known to those skilled in the art, and specific model structures will not be listed one by one.

[0056] Furthermore, it also includes a rechargeable battery (not shown), which is electrically connected to the temperature regulation component to facilitate carrying and using the wireless charging device.
