On the one hand, no additional active heat dissipation devices such as fans are required, which can reduce manufacturing costs and energy consumption during operation, making the wireless charger 100 more economical and efficient. On the other hand, the absence of active heat dissipation components such as fans means that the wireless charger 100 is almost silent when working, and the user experience is good.

The annular shell 21 is arranged to penetrate along the first direction, and the inner side wall of the annular shell 21 is formed with a flange 21a, and the flange 21a divides the internal space of the annular shell 21 into a first cavity 21b and a second cavity 21c, and the first cavity 21b is connected to the second cavity 21c, and the wireless charging module 22 is located in the first cavity 21b and is arranged on the flange 21a, and the cavity wall of the second cavity 21c is formed with a second air port 2a, and the second air port 2a is connected to the air cavity 1d. In this way, the airflow can enter the air cavity 1d from the first air port 1b arranged along the first direction to dissipate heat from the middle to the peripheral side of the wireless charging module 22, and finally be discharged from the mounting port 1c through the second air port 2a from the peripheral side annular cavity 1e or be discharged from the third air port 3a from the air flow channel in the wireless charging module 22; or, the airflow can enter the peripheral side annular cavity 1e from the mounting port 1c, and then enter the air cavity 1d through the second air port 2a to dissipate heat from the wireless charging module 22 in the air cavity 1d, and finally be discharged through the first air port 1b or be discharged from the air flow channel in the wireless charging module 22 from the third air port 3a; or, the airflow can enter the air cavity 1d from the third air port 3a through the air flow channel to dissipate heat from the wireless charging module 22 in the air cavity 1d, and finally be discharged from the first air port 1b or be discharged from the mounting port 1c from the peripheral side annular cavity 1e through the second air port 2a. In this way, the heat dissipation area of ​​the wireless charging module 22 can be increased, and the heat dissipation effect is better.

[0038] Illustratively, in one embodiment, the annular shell 21 and the necked portion 1a1 can be snap-connected or screw-connected. For example, the necked portion 1a1 is formed with a first positioning hole, and the flange 21a is formed with a second positioning hole. Then, fasteners such as bolts or screws can be used to pass through the first positioning hole and the second positioning hole to connect the annular shell 21 and the outer shell 1, thereby improving the connection strength between the annular shell 21 and the outer shell 1 and improving working stability.

[0039] For example, in one embodiment, please refer to Figure 3 , Figure 7 and Figure 8 The shape of the first air outlet 1b is not limited. For example, the projection shape of the first air outlet 1b along the first direction can be a curved long strip.

[0040] In one embodiment, there are multiple first air ports 1 b , and the multiple first air ports 1 b are arranged at intervals along the circumferential direction.

[0041] For example, the number of the first air vents 1b can be three, and the three first air vents 1b are arranged axially at intervals of 120° on a side wall of the housing 1 away from the wireless charging component 2 along the first direction to roughly enclose an annular area. In this way, the airflow can be further accelerated.

[0042] In one embodiment, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.11 There are multiple second air ports 2 a, and the multiple second air ports 2 a are arranged at intervals along the circumferential direction of the annular shell 21.

[0043] Exemplarily, the number of the second air outlets 2a can be two or more. By arranging a plurality of second air outlets 2a at intervals along the circumferential direction of the ring shell 21, air can be introduced or exhausted along the circumferential direction, increasing the air intake or exhaust volume, thereby increasing the heat dissipation of the wireless charging module 22, reducing the occurrence of heat accumulation, and improving the service life of the wireless charging module 22.

[0044] In one embodiment, please refer to Figures 4 to 10 The wireless charging module 22 includes a mounting disk 221, a coil 222 and a circuit board 223. The mounting disk 221 is arranged in the annular shell 21, the circuit board 223 is arranged on the mounting disk 221, the coil 222 is arranged on the side of the circuit board 223 away from the mounting disk 221 along the first direction, a gap space 223a is formed between the circuit board 223 and the mounting disk 221 along the first direction, the components of the circuit board 223 are arranged on the end surface of the circuit board 223 located in the gap space 223a, the mounting disk 221 is formed with an air guide port 221a, the air guide port 221a communicates with the air cavity 1d and the gap space 223a, the circuit board 223 is formed with a wiring hole 223b, the wiring hole 223b is connected to the third air port 3a, and the wiring hole 223b, the gap space 223a and the air guide port 221a jointly form an air flow channel.

[0045] Exemplarily, the mounting plate 221 can be arranged in the first cavity 21b, so that the mounting plate 221 can be protected to a certain extent and its service life can be improved. In this way, the airflow can enter the gap space 223a through the air guide port 221a to dissipate heat for the components of the circuit board 223 located in the gap space 223a, and dissipate heat for the coil 222 arranged on the circuit board 223 away from the mounting plate 221 along the first direction through the wiring hole 223b, or the airflow can dissipate heat for the coil 222 through the third air port 3a, and dissipate heat for the components located in the gap space 223a through the wiring hole 223b, so as to reduce heat accumulation.

[0046] It should be noted that a coil is also provided inside the electronic device. Through the principle of electromagnetic induction, the coil inside the electronic device generates current after receiving the variable magnetic field emitted by the coil 222 in the wireless charger 100 to charge the battery in the electronic device.

[0047] In one embodiment, please refer to Figure 6 , Fig. 9 and Fig.10 A portion of the mounting plate 221 is recessed along the first direction away from the circuit board 223 to form a gap groove 221b, a portion of the bottom surface of the gap groove 221b and one side of the gap groove 221b along the second direction are penetrated, a support portion 221b1 is formed on the bottom surface of the gap groove 221b, the support portion 221b1 protrudes along the first direction toward the circuit board 223, the circuit board 223 is supported by the support portion 221b1 to define a gap space 223a with the gap groove 221b, an air guide port 221a is formed between the support portion 221b1 and at least one side wall of the gap groove 221b along the third direction, and a wiring hole 223b is formed on the side of the wireless charging module 22 away from the air guide port 221a along the second direction, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0048] In this way, the airflow can enter the gap space 223a through the air guide port 221a to dissipate heat for the components of the wireless charging module 22 located in the gap space 223a, and dissipate heat for the wireless charging module 22 through the wiring hole 223b. Alternatively, the airflow can pass through the third air outlet 3a to dissipate heat for the end surface of the wireless charging module 22 away from the mounting plate 221 along the first direction, and dissipate heat for the components of the wireless charging module 22 located in the gap space 223a through the wiring hole 223b. Since the wiring hole 223b and the air guide port 221a are arranged along the second direction, the flow path of the airflow can be extended, the heat dissipation effect of the wireless charging module 22 is better, and heat accumulation can be effectively reduced.

[0049] It should be noted that Figure 3R1 may be the first direction, R2 may be the second direction, and R3 may be the third direction.

[0050] For example, in one embodiment, please refer to Fig.10 The support portion 221b1 can be arranged at the bottom surface of the gap groove 221b at the air guide port 221a, and air guide ports 221a are formed between the support portion 221b1 and the side walls of the gap groove 221b along the third direction. In this way, the air guide area can be increased and the heat dissipation effect can be better.

[0051] For example, in one embodiment, please refer to Figure 4 The wireless charging module 22 includes a baffle 4, and a mounting portion 221c is formed on the non-recessed portion of the mounting plate 221. The baffle 4 is fixedly mounted on the mounting portion 221c to cover the gap groove 221b, so that the mounting plate 221 can be cooperated with to limit the movement of the circuit board 223 along the first direction. The baffle 4 is formed with an avoidance opening 4a corresponding to the wiring hole 223b. The coil 222 can be arranged on the side of the baffle 4 away from the circuit board 223 along the first direction, and the wire of the coil 222 can be electrically connected to the components of the circuit board 223 through the avoidance opening 4a and the wiring hole 223b. In this way, the baffle 4 can block the coil 222 and the circuit board 223 along the first direction to reduce the heat transfer between the two.

[0052] Exemplarily, in one embodiment, the flange 21a on the annular shell 21 is formed with a third positioning hole, the mounting portion 221c of the mounting disk 221 is formed with a fourth positioning hole, and the baffle 4 is formed with a fifth mounting hole. Fasteners can then be passed through the third positioning hole, the fourth positioning hole, and the fifth positioning hole to connect the annular shell 21, the mounting disk 221, and the baffle 4, thereby improving the connection strength among the three and providing good working stability.

[0053] In one embodiment, please refer to Figure 1 and Figure 2 A charging area 3b corresponding to the wireless charging component 2 is arranged on the surface of the panel 3, and a plurality of third air outlets 3a are arranged at circumferential intervals around the charging area 3b.

[0054] Exemplarily, the wireless charging module 22 can charge the electronic device located in the charging area 3b.

[0055] In this way, by arranging a plurality of third air vents 3a at circumferential intervals along the charging area 3b on the panel 3, the electronic device can be cooled circumferentially while the wireless charging module 22 is cooled, thereby increasing the cooling area of ​​the electronic device, reducing heat accumulation, and improving the service life of the battery in the electronic device.

[0056] Exemplarily, in one embodiment, the electronic device may be a mobile phone, a tablet, a watch, or a headset, etc.

[0057] Exemplarily, in one embodiment, the shape of the charging area 3b is not limited, for example, it can be circular or square, etc.

[0058] Exemplarily, in one embodiment, the shape of the housing 1 is not limited. For example, the projection of the housing 1 along the first direction may be a circle.

[0059] In one embodiment, please refer to Figure 1 and Figure 2 The arrangement direction of the third air outlet 3a and the first air outlet 1b is the first direction, and the portion of the panel 3 where the charging area 3b and the third air outlet 3a are arranged is the heat dissipation area 3c, and the heat dissipation area 3c is recessed along the first direction toward the direction close to the wireless charging component 2 to form a groove 3d.

[0060] Here, by recessing the heat dissipation area 3c along the first direction toward the wireless charging component 2 to form a groove 3d, the gap between the electronic device and the heat dissipation area 3c along the first direction can be increased to increase the heat dissipation space for the electronic device and further improve the heat dissipation effect of the electronic device.

[0061] In one embodiment, please refer to Figure 1 and Figure 2 The panel 3 is formed with a heat dissipation groove 3e, which is located outside the heat dissipation area 3c. The opening direction of the heat dissipation groove 3e is set along the first direction away from the wireless charging component 2, and the heat dissipation groove 3e is connected to the groove 3d.

[0062] Exemplarily, the third air outlet 3a can be located between the charging area 3b and the heat dissipation groove 3e along the radial direction of the mounting plate 221. Here, by connecting the heat dissipation groove 3e with the groove 3d, on the one hand, the airflow of the third air outlet 3a in the groove 3d can dissipate heat for the electronic device through the heat dissipation groove 3e, further increasing the heat dissipation area for the electronic device, and the heat dissipation efficiency is high; on the other hand, the heat generated by the wireless heat dissipation component can be dissipated faster through the heat dissipation groove 3e and the third air outlet 3a, reducing the occurrence of heat accumulation in the housing 1.

[0063] Exemplarily, in one embodiment, the shape of the heat dissipation slot 3e is not limited. For example, the shape of the heat dissipation slot 3e along the projection of the first direction may be a parallelogram.

[0064] In one embodiment, please refer to Figure 1 and Figure 2 There are multiple heat dissipation grooves 3e, and the multiple heat dissipation grooves 3e are arranged at intervals along the circumference of the heat dissipation area 3c.

[0065] For example, the number of the heat dissipation grooves 3e can be three, and the three heat dissipation grooves 3e can be arranged at intervals of 120° along the circumference of the heat dissipation area 3c. In this way, the heat dissipation effect of the wireless charging component 2 and the electronic device can be further improved.

[0066] Exemplarily, in one embodiment, the wireless charger 100 includes a magnet, which can be arranged around the periphery of the wireless charging module 22. An adsorption area 3f is formed on the panel 3 at a position corresponding to the magnet. The adsorption area 3f is arranged around the periphery of the heat dissipation area 3c. The adsorption area 3f is formed with a heat dissipation groove 3e. A magnet or iron sheet is arranged in the electronic device, so that the electronic device can be stably attracted.

[0067] In one embodiment, the wireless charger 100 includes an air guide member, which is disposed on the panel 3 . The air guide member forms an air guide channel, and the air guide channel is connected to the installation port 1c located at the annular cavity 1e .

[0068] Exemplarily, a portion of the wireless charging component 2 protrudes out of the mounting port 1c, and the air guide member can be arranged on the outside of the adsorption area 3f of the panel 3 along the radial direction of the mounting disk 221. For example, one end of the air guide member can be connected to the panel 3 located on the outside of the adsorption area 3f, and the other end of the air guide member extends outward along the radial direction of the mounting disk 221 to define an air guide channel with the side of the outer shell 1 away from the first air outlet 1b along the first direction, and the air guide channel is connected to the mounting port 1c located at the annular cavity 1e. In this way, when the airflow enters the annular cavity 1e from the second air outlet 2a and is then discharged to the mounting port 1c, the air guide member forms an air guide channel to guide the discharged airflow in a direction away from the panel 3, thereby reducing the airflow after heat dissipation from blowing directly to the user, and providing a good user experience.

[0069] In one embodiment, please refer to Figure 1 and Figure 8 The wireless charger 100 includes a support rod 5, a ball head 5a is formed at one end of the support rod 5, an air cavity 1d is provided with a rotating portion 1d1, the rotating portion 1d1 is formed with a rotating cavity 1d11, and the ball head 5a is rotatably arranged in the rotating cavity 1d11.

[0070] Exemplarily, the wireless charger 100 includes a base 6, and the support rod 5 is connected between the base 6 and the housing 1 along the second direction. The rotating portion 1d1 can be arranged on the cavity wall of the air cavity 1d away from the wireless charging component 2 along the first direction. By forming a rotating cavity 1d11 in the rotating portion 1d1, the ball head 5a can rotate in the rotating cavity 1d11. In this way, on the one hand, the ball head 5a located in the rotating cavity 1d11 can be protected to a certain extent and its service life can be improved; on the other hand, through the rotation cooperation of the ball head 5a and the rotating cavity 1d11, universal adjustment can be achieved to meet more rotation directions of the housing 1, so as to better adapt to the user's placement requirements for electronic devices, with high convenience of use and good user experience.

[0071] For example, in one embodiment, the base 6 has a socket for inserting an external power source, and a wiring channel is formed in the connecting rod. The wires of the wireless charging module 22 are electrically connected to the electric board in the socket through the wiring channel to supply power to the wireless charging module 22. In this way, the wires of the wireless charging module 22 can be hidden in the wiring channel to avoid being exposed, which improves the safety of use and improves the simplicity and aesthetics of the appearance of the wireless charger 100.

[0072] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present application are included in the protection scope of the present application.
