[0032] A wireless charger provided in the present application embodiment is shown in FIG. Figures 1 to 9 The wireless charger 100 includes a housing 1, a wireless charging component and a heat sink 3. The housing 1 is formed with a housing cavity 1a and a first air outlet 1b and a mounting port 1c connected to the housing cavity 1a. The wireless charging component is arranged in the housing cavity 1a through the mounting port 1c to define an inner cavity 1d in the housing cavity 1a. The inner cavity 1d is connected to the first air outlet 1b. The outer peripheral wall of the wireless charging component and the cavity wall of the housing cavity 1a are spaced to form an annular gap 1e. The annular gap 1e is connected to the mounting port 1c. The outer peripheral wall of the wireless charging component is formed with a second air outlet 2a. The second air outlet 2a is connected to the annular gap 1e and the inner cavity 1d. The heat sink 3 is arranged in the inner cavity 1d. The heat sink 3 is used to drive the gas flow in the inner cavity 1d to dissipate heat from the wireless charging component.

[0033] The wireless charger 100 provided in the present application has a housing 1 with a housing 1a and a mounting port 1c, so that the wireless charging component and the heat sink 3 can be installed in the housing 1a through the mounting port 1c, so as to protect the wireless charging component and the heat sink 3 to a certain extent and improve their service life; the heat sink 3 is arranged in the inner cavity 1d to drive the airflow, so that the airflow can enter the inner cavity 1d from the first air port 1b to dissipate the heat of the wireless charging component, and then enter the annular gap 1e through the second air port 2a, and finally flow out through the mounting port 1c. Of course, the airflow can also enter the annular gap 1e from the mounting port 1c, and then enter the inner cavity 1d through the second air port 2a, and finally flow out from the first air port 1b on the outer shell 1. In this way, efficient air convection can be achieved through the heat sink 3, the situation of heat accumulation in the outer shell 1 is reduced, the heat on the wireless charging component can be dissipated relatively quickly, the temperature of the wireless charging component is reduced, and it is kept in a good temperature environment, so that the charging efficiency and service life can be improved.

[0034] In one embodiment, please refer to Figures 1 to 5 , the arrangement direction of the installation port 1c and the first air outlet 1b is the first direction, the wireless charging assembly includes a ring shell 21 and a wireless charging module, the outer peripheral wall of the ring shell 21 and the peripheral wall of the accommodating cavity 1a define an annular gap 1e, the ring shell 21 is arranged to penetrate along the first direction, the wireless charging module is arranged in the ring shell 21 to define an inner cavity 1d in the accommodating cavity 1a, and a second air outlet 2a is formed on the outer peripheral wall of the ring shell 21 on the side away from the wireless charging module along the first direction.

[0035] Exemplarily, the cavity wall of the accommodating cavity 1a is formed with a constricted portion 1a1, the caliber of the constricted portion 1a1 is smaller than the caliber of the mounting port 1c, the side of the annular shell 21 close to the heat sink 3 along the first direction is in contact with the constricted portion 1a1, and the outer peripheral wall of the annular shell 21 is spaced apart from the cavity wall of the accommodating cavity 1a located between the constricted portion 1a1 and the mounting port 1c to form an annular gap 1e. 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 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 inner cavity 1d. In this way, the airflow can enter the inner 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, and finally be discharged from the mounting port 1c through the second air port 2a from the annular gap 1e on the peripheral side. Alternatively, the airflow can enter the annular gap 1e on the peripheral side from the mounting port 1c, and then enter the inner cavity 1d through the second air port 2a to dissipate heat from the wireless charging module in the inner cavity 1d, and finally be discharged through the first air port 1b. In this way, the heat dissipation area of ​​the wireless charging module by the airflow can be increased, and the heat dissipation effect is better.

[0036] For example, in one embodiment, please refer to Figures 3 to 6 The ring shell 21 and the necking portion 1a1 can be connected by snapping or screwing. For example, the necking portion 1a1 is formed with a first positioning hole 1a11, and the flange 21a is formed with a second positioning hole 21a1. Then, fasteners such as bolts or screws can be used to pass through the first positioning hole 1a11 and the second positioning hole 21a1 to connect the ring shell 21 and the outer shell 1, thereby improving the connection strength between the ring shell 21 and the outer shell 1 and improving the working stability.

[0037] In one embodiment, please refer to Figures 2 to 5 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.

[0038] 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, reducing the occurrence of heat accumulation, and improving the service life of the wireless charging module.

[0039] It should be noted that Figure 1 The R1 in the figure may be a first direction. For example, the first direction may be a front-to-back direction.

[0040] It should be noted that the front refers to the direction toward the user, and the bottom and back are opposite to the front.

[0041] In one embodiment, please refer to Figure 5 , Figure 7 , Figure 8 and Fig. 9 The wireless charger 100 includes a mounting plate 4, which is disposed in the annular shell 21. A portion of the mounting plate 4 is recessed along a first direction toward the heat sink 3 to form a gap groove 4a. The wireless charging module is disposed in the gap groove 4a. A portion of the bottom surface of the gap groove 4a is penetrated along the first direction to form a connecting port 4a1, and the connecting port 4a1 is connected to the inner cavity 1d.

[0042] Exemplarily, the mounting plate 4 can be disposed in the first cavity 21b, so that the mounting plate 4 can be protected to a certain extent and its service life can be improved. A portion of the mounting plate 4 is formed with a gap groove 4a along the first direction toward the direction close to the heat sink 3, and the wireless charging module can be disposed in the gap groove 4a, so that the protection of the wireless charging module can be improved, and then its service life can be improved. A connecting port 4a1 is formed on a portion of the bottom surface of the gap groove 4a that passes through along the first direction, and the connecting port 4a1 is connected to the inner cavity 1d, so that the airflow in the inner cavity 1d can directly dissipate the heat to the wireless charging module through the connecting port 4a1, which has a good heat dissipation effect and reduces heat accumulation.

[0043] In one embodiment, please refer to Figure 5 and Figure 7 The wireless charging module includes a circuit board 221, a coil 222 and a baffle 223. The circuit board 221 is arranged in the gap groove 4a. The non-recessed part of the mounting plate 4 is formed with a mounting portion 4b. The mounting portion 4b is arranged around the circumference of the gap groove 4a. The baffle 223 is arranged on the mounting portion 4b, and the coil 222 is arranged on the baffle 223.

[0044] Here, by setting the circuit board 221 in the gap groove 4a, the airflow in the inner cavity 1d can directly dissipate the heat of the circuit board 221 through the connecting port 4a1, and the heat dissipation effect is good. By covering the gap groove 4a with the baffle 223 on the mounting portion 4b, the circuit board 221 can be limited to move along the first direction in cooperation with the mounting plate 4, thereby reducing the damage to the circuit board 221 when it is shaken or impacted. By setting the coil 222 on the baffle 223, the baffle 223 can block the coil 222 and the circuit board 221 along the first direction, thereby reducing the heat transfer between the two.

[0045] 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.

[0046] Exemplarily, in one embodiment, the electronic device may be a mobile phone, a tablet, a watch, or a headset, etc.

[0047] For example, in one embodiment, please refer to Figures 3 to 7 The connection between the annular shell 21 and the mounting disk 4 and between the mounting disk 4 and the baffle 223 can be a snap connection or a screw connection. For example, a third positioning hole 21a2 is formed on the flange 21a in the annular shell 21, a fourth positioning hole 4b1 is formed on the mounting portion 4b of the mounting disk 4, and a fifth positioning hole 223a is formed on the baffle 223. Fasteners such as screws or bolts can be used to pass through the third positioning hole 21a2, the fourth positioning hole 4b1 and the fifth positioning hole 223a to improve the connection strength among the baffle 223, the mounting disk 4 and the annular shell 21, and the working stability is good.

[0048] Exemplarily, in one embodiment, there is a distance between the mounting disk 4 and the heat sink 3 along the first direction. This not only reduces the damage of the heat sink 3 to the mounting disk 4 and the circuit board 221 on the mounting disk 4 when being driven, but also makes it easier for the heat sink 3 to drive the airflow.

[0049] In one embodiment, please refer to Figure 6The arrangement direction of the mounting port 1c and the first air port 1b is the first direction. The heat sink 3 includes a wind wheel 31, a driving member 32 and a mounting member 33. The mounting member 33 is arranged on the cavity wall of the inner cavity 1d. The mounting member 33 has a third air port 33a that passes through along the first direction. The third air port 33a is connected to the first air port 1b. The driving member 32 is arranged on the mounting member 33, and the driving member 32 is used to drive the wind wheel 31.

[0050] Exemplarily, the mounting member 33 can be mounted on the cavity wall of the inner cavity 1d away from the mounting plate 4 along the first direction by fasteners such as screws or bolts, and the mounting member 33 is formed with a third air port 33a penetrating along the first direction, and the third air port 33a is connected to the first air port 1b, so that the airflow can enter the inner cavity 1d through the first air port 1b and the third air port 33a or be discharged from the inner cavity 1d through the first air port 1b and the third air port 33a. The driving member 32 can be fixedly arranged on the mounting member 33 by fasteners such as screws or bolts, and the driving shaft of the driving member 32 can be connected to the wind wheel 31. The driving member 32 drives the wind wheel 31 to rotate to achieve more efficient air convection, so that the coil 222 and the circuit board 221 can quickly dissipate heat.

[0051] Exemplarily, in one embodiment, the shapes of the first air outlet 1b and the third air outlet 33a are not limited. For example, the projection shape of the first air outlet 1b and the third air outlet 33a along the first direction may be a curved long strip.

[0052] In one embodiment, please refer to Figure 3 and Figure 6 The number of the third air outlets 33a and the number of the first air outlets 1b are both multiple, and the multiple third air outlets 33a are arranged at intervals along the circumference of the wind wheel 31. The first air outlet 1b and the third air outlets 33a are arranged correspondingly, and each third air outlet 33a is connected to the corresponding first air outlet 1b.

[0053] For example, the number of the third air ports 33a and the number of the first air ports 1b can both be three, and the three third air ports 33a are arranged at intervals of 120° along the circumference of the wind wheel 31, and the three first air ports 1b are arranged correspondingly, so that the three first air ports 1b and the three third air ports 33a are each roughly arranged to form an annular area. In this way, the airflow can be further accelerated.

[0055] Exemplarily, the rotating portion 1d1 can be arranged on the cavity wall of the inner cavity 1d away from the mounting member 33 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, so that, 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 meet the user's requirements for the placement of the electronic device, with high convenience of use and good user experience.

[0056] In one embodiment, please refer to Figure 1 The wireless charger 100 includes a base 6, a support rod 5 connected between the base 6 and the housing 1, a socket 6a for inserting an external power source is formed in the base 6, a wiring channel is formed in the support rod 5, and the wires of the wireless charging component are electrically connected to the electric board in the socket 6a through the wiring channel to power the wireless charging component.

The wires of the wireless charging module pass through the first wiring channel, the second wiring channel and the third wiring channel to be electrically connected to the electric board in the socket 6a in the base 6 to power the wireless charging module.

[0059] Exemplarily, the panel 7 can be arranged on the side of the wireless charging component away from the heat sink 3 along the first direction. Here, since there is an installation gap between the wireless charging module and the installation plate 4, while dissipating the heat of the wireless charging component, the airflow can also be discharged from the fourth air outlet 7a through the installation gap. In this way, not only can the heat of the wireless charging component be dissipated from the fourth air outlet 7a, the heat dissipation effect of the wireless charging component is better, but the discharged airflow can also be used to dissipate the heat of the electronic device, reduce the occurrence of heat accumulation, and increase the service life of the battery in the electronic device.
