[0002] Wireless charging devices achieve charging based on the electromagnetic coupling of the transmitting coil and the receiving coil. The problem is that the heat generation area of ​​the wireless charging device is mainly concentrated in the transmitting coil and the main control board area. As a result, during charging, heat will cross between the transmitting coil and the main control board area. Consequently, the heat accumulation in the main control board area will cause the main control board to overheat, which will shorten the life of electronic components or even directly damage them. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a wireless charging device with anti-heat-spreading capability, which can effectively block heat spread between the coil module and the main control module, thus extending the service life of the wireless charging device.

[0004] A wireless charging device for preventing heat leakage according to an embodiment of this application includes a coil module, a main control module, a heat insulation component, a heat-conducting component, and a housing assembly;

[0005] The housing assembly has a receiving cavity, and the housing assembly includes a heat transfer part located in the receiving cavity. The receiving cavity contains a coil module, a main control module, a heat insulation component, and a heat conduction component arranged along the stacking direction. The heat insulation component abuts against the main control module, and the heat conduction component abuts against the heat transfer part.

If the main control module and the heat-conducting component are in contact, the heat generated by the main control module can be transferred to the heat-conducting component and the heat transfer part in sequence, and dissipated to the outside through the housing assembly. In addition to preventing heat leakage, it also helps to improve the heat dissipation efficiency of the main control module. Alternatively, if the coil module is in contact with the heat-conducting component, the heat generated by the coil module can be transferred sequentially to the heat-conducting component and the heat transfer part, and dissipated outward through the housing assembly. Furthermore, if the coil module and the main control module are spaced apart, and air is used to block heat transfer between the coil module and the main control module, then a heat insulation component is located between the main control module and the heat transfer part to block heat transfer from the heat transfer part to the main control module.

[0036] The embodiments of this application are described below with reference to the accompanying drawings:

[0037] refer to Figures 1 to 3 According to the embodiments of this application, the anti-heat-spreading wireless charging device can be a wireless charging charger, a power bank, a stand with wireless charging, or other devices with wireless charging function. The anti-heat-spreading wireless charging device includes a coil module 100, a main control module 200, a heat insulation component 310, a heat conduction component 320, and a housing assembly 400. The housing assembly 400 is provided with a receiving cavity 440. The housing assembly 400 includes a heat transfer part 430 located in the receiving cavity 440. The receiving cavity 440 contains the coil module 100, the main control module 200, the heat insulation component 310, and the heat conduction component 320 arranged along the stacking direction. The heat insulation component 310 abuts against the main control module 200, and the heat conduction component 320 abuts against the heat transfer part 430. Along the stacking direction, the heat insulation component 310 is located between the coil module 100 and the main control module 200. It should be understood that the heat insulation component 310 is located on the side of the main control module 200 facing the coil module 100.

[0038] Along the stacking direction, the side of the heat insulation component 310 facing away from the main control module 200 abuts against the heat transfer part 430. The heat conduction component 320 is located between the heat transfer part 430 and the coil module 100. The side of the heat conduction component 320 facing away from the heat transfer part 430 abuts against the coil module 100. The coil module 100 and the main control module 200 are arranged at intervals. This interval arrangement should be understood as the side of the main control module 200 facing the coil module 100 abutting against the heat insulation component 310 only, and the coil module 100 abutting against the heat transfer part 430 only through the heat conduction component 320, so as to achieve heat dissipation through the housing assembly 400 and the coil module 100 abutting against the main control module 200 at intervals. The heat-conducting component 320 is used to guide the heat generated by the coil module 100 to the housing assembly 400 and dissipate heat to the outside through the housing assembly 400. The heat insulation component 310 is used to block the heat transfer between the main control module 200 and the housing assembly 400, preventing the housing assembly 400 from transferring heat to the main control module 200. The gap between the coil module 100 and the main control module 200 allows air to act as a thermal resistance medium, limiting the heat transfer between the main control module 200 and the coil module 100.

[0039] Or, refer to Figure 6 and Figure 7 Along the stacking direction, the heat insulation component 310 abuts against the coil module 100 on the side away from the main control module 200, and the heat conduction component 320 is located between the heat transfer part 430 and the main control module 200, with the side of the heat conduction component 320 abutting against the heat transfer part 430 on the side away from the main control module 200. The heat insulation component 310 is used to directly block heat leakage between the coil module 100 and the main control module 200, preventing the heat from the coil module 100 from being transferred to the main control module 200 and causing the main control module 200 to overheat. The heat conduction component 320 is used to guide the heat generated by the main control module 200 to the housing assembly 400, and dissipate heat outward through the housing assembly 400, which is beneficial to improving the heat dissipation efficiency of the main control module 200.

[0040] In summary, the present application effectively improves the situation of poor local heat dissipation in wireless charging devices. On the one hand, it enables electronic components to operate at a more suitable temperature, ensuring the efficiency of wireless charging and making wireless charging safer and more reliable. On the other hand, it can also extend the service life of wireless charging devices.

[0041] refer to Figures 1 to 3 Specifically, the coil module 100 is electrically connected to the main control module 200. The main control module 200 provides alternating current to the coil module 100, causing the coil module 100 to generate an alternating magnetic field. When the receiving coil approaches the coil module 100, it is within the range of this alternating magnetic field. The magnetic flux in the receiving coil changes over time. Since the receiving coil is a closed coil, an induced electromotive force is generated in the receiving coil, which in turn generates an induced current, thus achieving energy transfer. During this process, both the coil module 100 and the main control module 200 generate heat.

[0042] Based on this, the heat insulation component 310 in this application can adopt a structure with high thermal resistance, such as aerogel, and the heat conducting component 320 can adopt a structure with high thermal conductivity, such as conductive cloth. The anti-heat-spreading wireless charging device in this application has at least two structural arrangements:

[0043] refer to Figure 6 and Figure 7First: The heat insulation component 310 is located between the coil module 100 and the main control module 200. One side of the heat insulation component 310 abuts against the main control module 200, and the opposite side abuts against the coil module 100. The heat insulation component 310 is used to support the coil module 100 and directly block heat transfer between the coil module 100 and the main control module 200. The heat-conducting component 320 can be located between the housing assembly 400 and the main control module 200. The portion of the main control module 200 that does not abut against the heat insulation component 310 can... The heat conductor 320 abuts against the heat conductor 320 and can fit against the cavity wall of the receiving cavity 440. The heat generated by the main control module 200 can be transferred to the heat conductor 320. Thus, the heat conductor 320 can further guide the heat to the housing assembly 400 and dissipate it outward through the housing assembly 400 to achieve heat dissipation. This makes the heat distribution more uniform, facilitates more effective control of the temperature of the main control module 200, prevents the main control module 200 from overheating, and extends the service life of the wireless charging device.

[0044] refer to Figure 3 and Figure 4 Second: The coil module 100 and the main control module 200 are arranged at a distance, with air between them as a thermal insulation medium to limit heat transfer between them. The heat-conducting component 320 abuts against the coil module 100, allowing heat generated by the coil module 100 to be transferred to the heat-conducting component 320 (separated from the main control module 200). The heat-conducting component 320 then transfers the heat to the housing assembly 400 for outward dissipation, resulting in a more uniform heat distribution and improved heat dissipation efficiency. The heat insulation component 310 abuts against both the main control module 200 and the housing assembly 400. The heat insulation component 310 limits heat transfer from the housing assembly 400 to the main control module 200 to prevent overheating and ensure the charging stability of the wireless charging device.

[0045] refer to Figures 2 to 4In some embodiments, the housing assembly 400 includes a first housing 410 defining a portion of a receiving cavity 440. A heat transfer part 430 is located in the receiving cavity 440 and is connected to the first housing 410. Along the stacking direction, the heat transfer part 430 is located on the side of the main control module 200 facing the coil module 100. A heat-conducting element 320 is provided between the heat transfer part 430 and the coil module 100. The opposite sides of the heat-conducting element 320 abut against the heat transfer part 430 and the coil module 100, respectively. The heat generated by the coil module 100 can be transferred to the heat transfer part 430 through the heat-conducting element 320. Then, the heat transfer part 430 transfers the heat to the first housing 410 to achieve heat dissipation. This is beneficial to make the heat generated by the coil module 100 more dispersed, improve the heat dissipation efficiency of the coil module 100, and effectively avoid local overheating of the coil module 100. A heat insulation component 310 is provided between the heat transfer part 430 and the main control module 200. The heat insulation component 310 is used to limit the heat transfer between the main control module 200 and the heat transfer part 430, so as to limit the heat generated by the coil module 100 to be transferred to the main control module 200 in sequence through the heat conduction component 320 and the heat transfer part 430, effectively preventing the main control module 200 from overheating locally.

[0046] Specifically, the first housing 410 defines a portion of the receiving cavity 440, and the inner side of the first housing 410 is the cavity wall of the receiving cavity 440. The heat transfer part 430 may be provided with a through hole to divide the receiving cavity 440 into a connected first chamber 441 and a second chamber 442. The coil module 100 and the heat conductor 320 are located in the first chamber 441, and the main control module 200 and the heat insulation component 310 are located in the second chamber 442. The through hole can provide wiring between the main control module 200 and the coil module 100. The heat-conducting component 320 abuts against the coil module 100 on the side facing away from the main control module 200, and against the heat transfer part 430 on the side facing the main control module 200. The heat insulation component 310 abuts against the main control module 200, and the side of the heat insulation component 310 facing away from the main control module 200 abuts against the heat transfer part 430. Thus, the heat generated by the coil module 100 can be transferred to the heat-conducting component 320, the heat transfer part 430, and the first housing 410, resulting in a more uniform heat distribution and higher heat dissipation efficiency. Simultaneously, the heat insulation component 310 can block heat transfer between the heat transfer part 430 and the main control module 200, effectively preventing heat leakage from the coil module 100 to the main control module 200 and causing localized overheating of the coil module 100.

[0047] refer to Figures 2 to 4In some embodiments, the heat insulation component 310 partially covers the side of the main control module 200 facing the heat transfer part 430. The main control module 200, the heat insulation component 310, and the heat transfer part 430 together form a heat insulation space 443. Thus, the heat insulation component 310 and the heat insulation space 443 jointly block the heat transfer between the heat transfer part 430 and the main control module 200. Air in the heat insulation space 443 serves as the heat insulation medium. Therefore, while ensuring effective blocking of heat transfer between the heat transfer part 430 and the main control module 200, the use of the heat insulation component 310 can be reduced, which is beneficial to reducing the weight of the wireless charging device and saving costs. On the other hand, the heat insulation space 443 can also accommodate the electronic components of the main control module 200, avoiding compression of the electronic components.

[0048] Specifically, the heat insulation component 310 can be in the shape of a ring, a square, or a mesh. Taking a ring-shaped heat insulation component 310 as an example, the center of the heat insulation component 310 is a through hole. Along the axial direction of the through hole, one side of the heat insulation component 310 abuts against the main control module 200, and the opposite side of the heat insulation component 310 abuts against the heat transfer part 430. This allows the main control module 200, the heat insulation component 310, and the heat transfer part 430 to together enclose a heat insulation space 443. The heat insulation is part of the receiving cavity 440. Therefore, the main control module 200 includes the heat insulation component 310. The covered area and the exposed uncovered area are thermally isolated from the heat transfer part 430 by the heat insulation component 310, and the uncovered area is thermally isolated from the heat transfer part 430 by the air in the heat insulation space 443. Thus, this embodiment can reduce the use of the heat insulation component 310 to save costs while limiting the heat transfer between the main control module 200 and the heat transfer part 430. In addition, the heat insulation space 443 can accommodate the electronic components on the main control module 200 to avoid squeezing the electronic components, which is beneficial to ensuring the performance of the main control module 200.

[0049] refer to Figure 5 In some embodiments, the wireless charging device includes two heat insulation components 310. Along the stacking direction, one heat insulation component 310 is located on the side of the main control module 200 facing the coil module 100, and the other heat insulation component 310 is located on the side of the main control module 200 away from the coil module 100. Both heat insulation components 310 abut against the main control module 200 and the housing assembly 400. Through the two heat insulation components 310, the heat transfer between the main control module 200 and the housing assembly 400 can be further limited. That is, when the coil module 100 dissipates heat through the heat conductor 320 and the housing assembly 400, the heat can be further transferred to the main control module 200.

[0050] Specifically, to ensure heat dissipation of the main control module 200, a heat insulation component 310 covers a portion of the main control module 200 on either side. For example, the heat insulation component 310 can be annular. The heat insulation component 310 can be placed between the contact position of the main control module 200 and the housing assembly 400. In this way, while blocking the heat generated by the coil module 100 from being transferred to the main control module 200, it can also ensure that the main control module 200 can dissipate heat into the receiving cavity 440.

[0051] refer to Figures 2 to 4 In some embodiments, the housing assembly 400 includes a first housing 410 and a second housing 420, the first housing 410 and the second housing 420 are connected, the heat transfer part 430 is located in the receiving cavity 440, one of the first housing 410 and the second housing 420 is connected to the heat transfer part 430, the first housing 410 and the second housing 420 together define the receiving cavity 440, the heat transfer part 430 divides the receiving cavity 440 into a communicating first chamber 441 and a second chamber 442, the coil module 100 is located in the first chamber 441, and the main control module 200 is located in the second chamber 442, which facilitates independent heat dissipation between the coil module 100 and the main control module 200 and helps to limit mutual heat transfer between the coil module 100 and the main control module 200.

[0052] Specifically, the first housing 410 defines a first chamber 441, and the second housing 420 defines a second chamber 442. The heat transfer part 430 is provided with a through hole to ensure that the first chamber 441 and the second chamber 442 are connected. The heat-conducting element 320 abuts against the heat transfer part 430, and the heat insulation element 310 abuts against the heat transfer part 430. One of the coil module 100 and the main control module 200 abuts against the side of the heat-conducting element 320 away from the heat transfer part 430, so that the generated heat can be diffused to the first housing 410 or the second housing 420 through the heat-conducting element 320 and the heat transfer part 430. The other of the coil module 100 and the main control module 200 abuts against the side of the heat insulation element 310 away from the heat transfer part 430, so as to block the heat transfer of the heat transfer part 430, thereby preventing the heat transfer between the coil module 100 and the main control module 200.

[0053] refer to Figure 6 and Figure 7In some embodiments, the housing assembly 400 includes a first housing 410 defining a portion of a receiving cavity 440. A heat transfer portion 430 is located in the receiving cavity 440 and connected to the first housing 410. Along the stacking direction, the heat transfer portion 430 is located on the side of the main control module 200 facing the coil module 100. A heat-conducting element 320 is provided between the heat transfer portion 430 and the main control module 200. The opposite sides of the heat-conducting element 320 abut against the heat transfer portion 430 and the main control module 200, respectively. The heat generated by the main control module 200 can be transferred to the heat transfer portion 430 through the heat-conducting element 320. Then, the heat transfer portion 430 transfers the heat to the first housing 410 for heat dissipation, which is beneficial to make the heat generated by the main control module 200 more dispersed and to improve the heat dissipation efficiency of the main control module 200. The heat insulation component 310 is located between the coil module 100 and the main control module 200. It can provide support for the installation of the coil module 100 and limit the heat transfer between the main control module 200 and the heat transfer part 430 to prevent the main control module 200 from overheating.

[0054] Specifically, the first housing 410 defines a portion of the receiving cavity 440, and the inner side of the first housing 410 is the cavity wall of the receiving cavity 440. The heat transfer part 430 may be provided with through holes to divide the receiving cavity 440 into a connected first chamber 441 and a second chamber 442. The coil module 100 is located in the first chamber 441, and the main control module 200 and the heat conduction component 320 are located in the second chamber 442. The heat insulation component 310 extends from the first chamber 441 to the second chamber 442. The heat conduction component 320 abuts against the main control module 200, and the side of the heat conduction component 320 facing away from the main control module 200 abuts against the heat transfer part 430 to improve the heat dissipation efficiency of the main control module 200. One side of the heat insulation component 310 abuts against the main control module 200, and the other side of the heat insulation component 310 abuts against the coil module 100, so as to limit the heat transfer between the coil module 100 and the main control module 200. This facilitates further limiting the temperature rise of the main control module 200 and helps to extend the service life of the wireless charging device.

[0055] refer to Figure 6 and Figure 7 In some embodiments, the heat transfer part 430 is distributed around the outer peripheral wall of the heat insulation member 310, which helps to shorten the heat dissipation path of the main control module 200, so that the heat generated by the main control module 200 can be transferred to the first housing 410 more quickly through the heat conduction member 320 and the heat transfer part 430, thereby further improving the heat dissipation efficiency of the main control module 200.

[0056] refer to Figure 8In some embodiments, the wireless charging device includes two heat-conducting elements 320 along the stacking direction. One heat-conducting element 320 is located on the side of the main control module 200 facing the coil module 100, and the other heat-conducting element 320 is located on the side of the main control module 200 away from the coil module 100. Both heat-conducting elements 320 abut against the main control module 200 and the housing assembly 400. The two heat-conducting elements 320 further improve the heat transfer efficiency between the main control module 200 and the housing assembly 400, thereby further improving the heat dissipation efficiency of the main control module 200.

[0057] refer to Figures 3 to 8 In some embodiments, the main control module 200 includes a main control board and multiple electronic components, each of which is connected to the side of the main control board away from the coil module 100. Specifically, the main heat source of the main control module 200 is the electronic components. Placing the electronic components on the side of the main control board away from the coil module 100 can further block heat transfer between the coil module 100 and the main control module 200 through the main control board.

[0058] refer to Figures 1 to 8 In some embodiments, the housing assembly 400 includes a first housing 410 and a second housing 420, which are connected to define a receiving cavity 440. The thermal conductivity of the first housing 410 is greater than that of the second housing 420. The first housing 410 may be made of a material with high thermal conductivity, such as metal, and is mainly used to abut against the heat-conducting component 320 to ensure heat dissipation of the coil module 100 or the main control module 200, so that the heat generated by the coil module 100 or the main control module 200 can be transferred to the first housing more quickly. 410 dissipates heat. The second housing 420 can be made of a material with a low thermal conductivity, such as plastic, to block the heat from the first housing 410 from being transferred to the second housing 420. Thus, one of the first housing 410 and the second housing 420 can carry the coil module 100, and the other can carry the main control module 200. Based on the separation of the coil module 100 and the main control module 200, the heat generated by both can be blocked from being transferred through the path of the first housing 410 and the second housing 420, further limiting the heat transfer between the coil module 100 and the main control module 200.
