DETAILED DESCRIPTION

[0025] With the popularization of cars and the increasingly wide range of car usage scenarios, roof racks have also developed more uses. In addition to common functions such as roof storage boxes and bicycle rack systems, roof racks can also be used to install roof tent systems to expand the functions of RVs. Even with the popularization of drones, roof racks can be expanded into drone platforms.

[0026] Moreover, with the application of these new functions, how to power rooftop electrical equipment such as tent systems or drones has become an urgent problem to be solved. The existing idea is usually to power the rooftop electrical equipment through dedicated wiring harnesses. However, using wiring harnesses for power supply requires opening holes in the body. This, on the one hand, will affect the sealing of the body. On the other hand, the position of the body opening is relatively fixed, which greatly restricts the installation position of the rooftop electrical equipment.

[0027] See also Figure 1-Figure 5 In order to solve the problems of poor sealing and limited installation location of electrical equipment when using a wiring harness to power electrical equipment on the roof, the present application provides a wireless power supply system and a vehicle. The wireless power supply system includes a power transmission module 100, a power receiving module 200 and an insulating partition 300. The power transmission module 100 and the power receiving module 200 are respectively arranged on both sides of the insulating partition 300. Specifically, the insulating partition 300 can be a glass sunroof (or a resin sunroof), the power transmission module 100 is arranged on the inner side of the glass sunroof, and the power receiving module 200 is arranged on the outer side of the glass sunroof.

[0028] The power transmission module 100 includes a first mounting assembly 110 and a primary electromagnetic induction coil 120. The primary electromagnetic induction coil 120 can be removably mounted on one side of the insulating partition 300 via the first mounting assembly 110. The power receiving module 200 includes a second mounting assembly 210 and a secondary electromagnetic induction coil 220. The secondary electromagnetic induction coil 220 can be removably mounted on the other side of the insulating partition 300 via the second mounting assembly 210.

[0029] When alternating current flows through the primary electromagnetic induction coil 120, the primary electromagnetic induction coil 120 generates a changing magnetic field. This changing magnetic field generates an induced electromotive force in the secondary electromagnetic induction coil 220, causing the power receiving module 200 to output an induced current, thereby transmitting electrical energy from the power transmission module 100 to the power receiving module 200.

[0030] It should be noted that the wireless power supply system provided in this application can not only be used for powering the roof of a vehicle, but can also be used to penetrate the surface of any insulating partition 300 (including but not limited to side windows, front and rear windows, sunroofs, and plastic trim panels) to provide contactless power supply. In addition, this wireless power supply system is not limited to vehicle use and can also be used in other non-vehicle environments to provide wireless power through the surface of an insulating partition 300.

[0031] It should be noted that if Figure 4 As shown, the power transmission module 100 is provided with a first electrical interface 140 for connecting to an external power transmission line, and the power receiving module 200 is provided with a second electrical interface (not shown) for connecting to an external power-consuming device. In addition, the first electrical interface 140 and the second electrical interface can be type-C interfaces or other types of interfaces, which are not listed here.

[0032] Furthermore, the power receiving module 200 can be integrated into different electrical devices, exist as a wireless charging plug, and can also be used as a wireless adapter in conjunction with wired electrical appliances.

[0033] With this arrangement, on the one hand, because the power transmission module 100 and the power receiving module 200 transmit electrical energy through the electromagnetic induction effect between the primary electromagnetic induction coil 120 and the secondary electromagnetic induction coil 220, there is no need to install a connecting wire harness between the power transmission module 100 and the power receiving module 200. Consequently, there is no need to open a hole in the installation area to pass the connecting wire harness, thereby greatly improving the sealing of the installation area (including but not limited to the roof, side of the vehicle, or other installation areas, not listed here).

[0034] On the other hand, since the first mounting assembly 110 and the second mounting assembly 210 are respectively detachably mounted on both sides of the insulating partition 300, the installation positions of the power transmission module 100 and the power receiving module 200 can be adjusted by disassembling and moving the first mounting assembly 110 and the second mounting assembly 210, thereby greatly improving the installation flexibility of the wireless power supply system.

[0035] In one embodiment, if Figure 2 and Figure 4 As shown, the first mounting assembly 110 includes a first supporting frame 111 and a first insulating thermally conductive gasket 112. The first supporting frame 111 is a heat-conducting member. The first supporting frame 111 is provided with a first mounting groove 1111. The opening of the first mounting groove 1111 faces the power receiving module 200. The primary electromagnetic induction coil 120 is installed in the first mounting groove 1111. The first insulating thermally conductive gasket 112 is arranged between the primary electromagnetic induction coil 120 and the inner wall of the first mounting groove 1111, so that the heat generated by the primary electromagnetic induction coil 120 can be transferred to the first supporting frame 111 through the first insulating thermally conductive gasket 112.

[0036] With such a configuration, on the one hand, the assembly stability of the primary electromagnetic induction coil 120 and the first mounting assembly 110 can be improved; on the other hand, the first insulating thermally conductive gasket 112 can increase the indirect contact area between the primary electromagnetic induction coil 120 and the first support frame 111, thereby improving the heat dissipation effect of the primary electromagnetic induction coil 120. Moreover, since the first support frame 111 is a heat conductor, after the heat is transferred to the first support frame 111, it can be dissipated into the atmosphere through the first support frame 111.

[0037] Specifically, in one embodiment, the material of the first insulating thermally conductive gasket 112 includes but is not limited to: inorganic non-metallic thermally conductive insulating materials (such as chlorine trioxide ceramics, aluminum nitride ceramics or silicon carbide ceramics, etc., not listed here one by one) and polymer-based thermally conductive insulating materials (such as high thermal conductivity epoxy resin or high thermal conductivity silicone rubber, etc., not listed here one by one).

[0038] The above materials not only have high thermal conductivity, but also have excellent insulation properties, mechanical properties, high temperature resistance and chemical corrosion resistance.

[0039] In one embodiment, the material of the first supporting frame 111 includes but is not limited to aluminum, iron, copper or alloys of various metals.

[0040] But not limited to this, in other embodiments, the material of the first support frame 111 can also be a composite ceramic material, such as silicon nitride ceramic, silicon carbide ceramic or aluminum nitride ceramic, etc., which are not listed here one by one.

[0041] Furthermore, in one embodiment, if Figure 2 and Figure 4 As shown, the first insulating thermally conductive gasket 112 is attached to the inner wall of the first mounting groove 1111 . Specifically, the first insulating thermally conductive gasket 112 is bonded to the inner wall of the first mounting groove 1111 , or the first insulating thermally conductive gasket 112 is snapped onto the inner wall of the first mounting groove 1111 .

[0042] Such a configuration is helpful in preventing the first insulating thermally conductive gasket 112 from slipping relative to the first supporting frame 111 .

[0043] Furthermore, in one embodiment, if Figure 2-Figure 4 As shown, the first support frame 111 includes a first base 1112 and a first heat dissipation portion 1113, the first mounting groove 1111 is arranged on the first base 1112, the first heat dissipation portion 1113 is connected to one end of the first base 1112 away from the first mounting groove 1111, and the first heat dissipation portion 1113 is provided with a plurality of heat dissipation channels 1114 arranged through the first base 1112.

[0044] By setting up multiple through-going heat dissipation channels 1114, on the one hand, the total heat dissipation area of ​​the first support frame 111 can be increased, and on the other hand, cold air can enter from one end of the heat dissipation channel 1114, absorb heat through the inner wall of the heat dissipation channel 1114, and flow out from the other end of the heat dissipation channel 1114 to take away the heat of the first support frame 111, that is, the heat dissipation efficiency of the first support frame 111 is greatly improved.

[0045] Furthermore, in one embodiment, a plurality of heat dissipation channels 1114 are arranged in parallel, and each heat dissipation channel 1114 extends in the same direction.

[0046] Such a configuration is beneficial for multiple heat dissipation channels 1114 to perform synchronous and centralized heat dissipation.

[0047] Specifically, the first base 1112 forms the bottom wall of the heat dissipation channel 1114. Figure 2-Figure 4 As shown, multiple parallel first side plates 1115 are spaced apart to form side walls of the heat dissipation channel 1114 , and a first cover plate is connected to and covers one end of the first side plate 1115 away from the first base 1112 to form a top wall of the heat dissipation channel 1114 .

[0048] In one embodiment, if Figure 2 and Figure 3 As shown, the power transmission module 100 further includes a cooling fan 130 . The cooling fan 130 is disposed at one end of the heat dissipation channel 1114 so that airflow can flow along the heat dissipation channel 1114 .

[0049] Such an arrangement further accelerates the heat dissipation rate of the first heat dissipation portion 1113 .

[0050] Specifically, in one embodiment, Figure 3 As shown, the first heat dissipation portion 1113 is provided with an air flow groove 1116 with a circular cross-section. The air flow groove 1116 connects each heat dissipation channel 1114. The cooling fan 130 is arranged in the air flow groove 1116. Moreover, according to the width of the heat dissipation channel 1114, multiple air flow grooves 1116 can be set along the arrangement direction of the multiple heat dissipation channels 1114, and each air flow groove 1116 is correspondingly provided with a cooling fan 130.

[0051] In one embodiment, if Figure 2 and Figure 4 As shown, the power transmission module 100 further includes a housing 150 , which is disposed on the outside of the first mounting assembly 110 , the primary electromagnetic induction coil 120 and the cooling fan 130 .

[0052] It should be noted that the first cover plate may be a part of the housing 150 .

[0053] In one embodiment, if Figure 2 and Figure 4 As shown, the wireless power supply system further includes a first buffer washer 400 . The first buffer washer 400 is disposed between the power transmission module 100 and the insulating partition 300 , and the first buffer washer 400 is disposed around the outer periphery of the primary electromagnetic induction coil 120 .

[0054] It should be noted that “the first buffer washer 400 is arranged around the outer circumference of the primary electromagnetic induction coil 120” means that the orthographic projection of the first buffer washer 400 on the insulating partition 300 covers the orthographic projection of the primary electromagnetic induction coil 120 on the insulating partition 300, and the first buffer washer 400 and the primary electromagnetic induction coil 120 are not nested with each other.

[0055] First, the first buffer washer 400 has a buffering effect, which can prevent the primary electromagnetic induction coil 120 and the first mounting assembly 110 from directly contacting the insulating partition 300 and causing damage to the insulating partition 300 .

[0056] Furthermore, since the first buffer washer 400 is disposed around the outer periphery of the primary electromagnetic induction coil 120 , this configuration allows the end surface of the power transmission module 100 facing the insulating partition 300 to have a certain curvature, thereby improving the surface adaptability of the power transmission module 100 .

[0057] Specifically, the material of the first buffer gasket 400 includes but is not limited to glass fiber, asbestos, rock wool, silicate, aerogel felt and vacuum board, etc., which are not listed here one by one.

[0058] In one embodiment, if Figure 2 and Figure 5As shown, the second mounting assembly 210 includes a second support frame 211 and a second insulating thermally conductive gasket 212. The second support frame 211 is a heat-conducting component. The second support frame 211 is provided with a second mounting groove 2111. The opening of the second mounting groove 2111 faces the power transmission module 100. The secondary electromagnetic induction coil 220 is mounted in the second mounting groove 2111. The second insulating thermally conductive gasket 212 is disposed between the secondary electromagnetic induction coil 220 and the inner wall of the second mounting groove 2111 so that the heat generated by the secondary electromagnetic induction coil 220 can be transferred to the second support frame 211 through the second insulating thermally conductive gasket 212.

[0059] With such a configuration, on the one hand, the assembly stability of the secondary electromagnetic induction coil 220 and the second mounting assembly 210 can be improved; on the other hand, the second insulating thermally conductive gasket 212 can increase the indirect contact area between the secondary electromagnetic induction coil 220 and the second support frame 211, thereby improving the heat dissipation effect of the secondary electromagnetic induction coil 220. Moreover, since the second support frame 211 is a heat conductive component, after the heat is transferred to the second support frame 211, it can be dissipated into the atmosphere through the second support frame 211.

[0060] Specifically, in one embodiment, the material of the second insulating thermally conductive gasket 212 includes but is not limited to: inorganic non-metallic thermally conductive insulating materials (such as chlorine trioxide ceramics, aluminum nitride ceramics or silicon carbide ceramics, etc., not listed here one by one) and polymer-based thermally conductive insulating materials (such as high thermal conductivity epoxy resin or high thermal conductivity silicone rubber, etc., not listed here one by one).

[0061] The above materials not only have high thermal conductivity, but also have excellent insulation properties, mechanical properties, high temperature resistance and chemical corrosion resistance.

[0062] In one embodiment, the material of the second supporting frame 211 includes but is not limited to aluminum, iron, copper or alloys of various metals.

[0063] However, the present invention is not limited thereto. In other embodiments, the second support frame 211 may be made of a composite ceramic material, such as silicon nitride ceramic, silicon carbide ceramic, or aluminum nitride ceramic, which are not listed here one by one.

[0064] Furthermore, in one embodiment, Figure 2 and Figure 5 As shown, the second insulating thermally conductive gasket 212 is attached to the inner wall of the second mounting groove 2111 . Specifically, the second insulating thermally conductive gasket 212 is bonded to the inner wall of the second mounting groove 2111 , or the second insulating thermally conductive gasket 212 is snapped onto the inner wall of the second mounting groove 2111 .

[0065] Such a configuration is helpful in preventing the second insulating thermally conductive gasket 212 from slipping relative to the second supporting frame 211 .

[0066] Furthermore, in one embodiment, if Figure 1 、 Figure 2 and Figure 5 As shown, the second support frame 211 includes a second base 2112 and a second heat dissipation portion 2113, the second mounting slot 2111 is arranged on the second base 2112, the second heat dissipation portion 2113 is connected to one end of the second base 2112 away from the second mounting slot 2111, and the second heat dissipation portion 2113 is provided with a plurality of heat dissipation slots 2114 arranged in parallel.

[0067] By providing a plurality of heat dissipation slots 2114 arranged in parallel, the total heat dissipation area of ​​the second supporting frame 211 can be significantly increased, thereby improving the heat dissipation efficiency of the second supporting frame 211 .

[0068] Furthermore, in one embodiment, each heat dissipation slot 2114 has the same extension direction and is disposed through the extension direction.

[0069] Such a configuration is beneficial for multiple heat dissipation slots 2114 to perform synchronous and centralized heat dissipation.

[0070] Specifically, if Figure 1 、 Figure 2 and Figure 5 As shown, the second base 2112 constitutes the bottom wall of the heat dissipation groove 2114, and a plurality of parallel second side plates 2115 are arranged at intervals to form the side walls of the heat dissipation groove 2114. It should be noted that the end of the heat dissipation groove 2114 away from the second base 2112 is the opening of the heat dissipation groove 2114, and the heat dissipation groove 2114 can be directly connected to the external space through its own opening.

[0071] Furthermore, in one embodiment, if Figure 1 、 Figure 2 and Figure 5 As shown, the second mounting assembly 210 also includes a handle 214, which is fixedly connected to the end of the second base 2112 away from the second mounting slot 2111. The handle 214 is provided with a grip hole (not shown) for holding, so that the operator can grasp the handle 214 through the grip hole and then lift the entire power receiving module 200.

[0072] In one embodiment, if Figure 2 and Figure 5 As shown, the second mounting assembly 210 further includes an insulating cover plate 215 , which is sealed and disposed at the opening of the second mounting groove 2111 to prevent the secondary electromagnetic induction coil 220 from falling off from the second mounting groove 2111 .

[0073] Specifically, the material of the insulating cover plate 215 includes but is not limited to glass, ceramic, aerogel felt, vacuum plate, etc., which are not listed here one by one.

[0074] It should be noted that the insulating cover 215 is detachably connected to the second base 2112 via fasteners, or the insulating cover 215 is snap-fitted to the second base 2112 .

[0075] Furthermore, in one embodiment, the second mounting assembly 210 further includes a sealing ring (not shown), which is disposed around the outer periphery of the opening of the second mounting groove 2111, and the sealing ring is sealingly clamped between the insulating cover 215 and the second support frame 211 (second base 2112) to improve the waterproof and dustproof performance of the second mounting groove 2111, and facilitate the power receiving module 200 to adapt to various outdoor environments, including but not limited to rainy, snowy weather and dusty weather, thereby ensuring that the power receiving module 200 can still be used stably under extreme conditions.

[0076] In one embodiment, if Figure 2 and Figure 5 As shown, the wireless power supply system further includes a second buffer washer 500 , which is disposed between the power receiving module 200 and the insulating partition 300 , and surrounds the outer periphery of the secondary electromagnetic induction coil 220 .

[0077] It should be noted that “the second buffer washer 500 is arranged around the outer peripheral side of the secondary electromagnetic induction coil 220” means that the orthographic projection of the second buffer washer 500 on the insulating partition 300 covers the orthographic projection of the secondary electromagnetic induction coil 220 on the insulating partition 300, and the second buffer washer 500 and the secondary electromagnetic induction coil 220 are not nested with each other.

[0078] First, the second buffer washer 500 has a buffering effect, which can prevent the secondary electromagnetic induction coil 220 and the second mounting assembly 210 from directly contacting the insulating partition 300 and causing damage to the insulating partition 300 .

[0079] Furthermore, since the second buffer washer 500 is disposed around the outer periphery of the secondary electromagnetic induction coil 220 , this configuration allows the end surface of the power receiving module 200 facing the insulating partition 300 to have a certain curvature, making the power receiving module 200 have better surface applicability.

[0080] Specifically, the material of the second buffer gasket 500 includes but is not limited to glass fiber, asbestos, rock wool, silicate, aerogel felt and vacuum board, etc., which are not listed here one by one.

[0081] In one embodiment, if Figure 2 As shown, the first mounting assembly 110 and the second mounting assembly 210 are magnetically connected.

[0082] However, the present invention is not limited thereto. In other embodiments, the first mounting assembly 110 and the second mounting assembly 210 may be respectively adsorbed on both side surfaces of the insulating partition 300 by vacuum suction cups.

[0083] Furthermore, in one embodiment, Figure 2 As shown, the first mounting component 110 includes a first magnetic component 113, and the second mounting component 210 includes a second magnetic component 213. The first magnetic component 113 is embedded in one end of the first mounting component 110 close to the insulating partition 300, and the second magnetic component 213 is embedded in one end of the second mounting component 210 close to the insulating partition 300.

[0084] It should be noted that the materials of the first magnetic member 113 and the second magnetic member 213 include but are not limited to electrical steel, nickel-based alloys, rare earth alloys, and ferrite materials, which are not listed here one by one.

[0085] The present application also provides a vehicle, which includes the wireless power supply system described in any one of the above embodiments.

[0086] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
