In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0036] The present application embodiment provides a wireless charger 100, see Figures 1 to 11 The wireless charger 100 includes a housing 1, a mounting plate 2, a wireless charging module, a cover plate 4 and a heat dissipation component 5. The housing 1 includes a shell 11 and an annular shell 12. The shell 11 is formed with a receiving cavity 11a and a mounting port 11b connected to the receiving cavity 11a. The annular shell 12 is arranged in the receiving cavity 11a to define an air cavity 11c in the receiving cavity 11a. The outer peripheral wall of the annular shell 12 is spaced from the cavity wall of the receiving cavity 11a to form an annular cavity 11d. The annular cavity 11d is connected to the mounting port 11b. The outer peripheral wall of the annular shell 12 is formed with a first air port 12a. The first air port 12a is connected to the annular cavity 11d and the air cavity 11c. The mounting plate 2 is arranged in the annular shell 12, and the mounting plate 2 forms an air guide port 2a. The wireless charging module is arranged on the mounting plate 2, and a gap space 2b is formed between the wireless charging module and the mounting plate 2. The wireless charging module is formed with a wiring hole 3a, and the gap space 2b is connected to the wiring hole 3a and the air guide port 2a. The cover plate 4 is arranged on the wireless charging module, and a second air outlet 4e is formed through the cover plate 4, and the second air outlet 4e is connected to the wiring hole 3a and the installation port 11b. The heat dissipation component 5 is arranged in the air cavity 11c, and the heat dissipation component 5 is used to drive the gas flow in the air cavity 11c to dissipate heat for the wireless charging module.

[0037] The wireless charger 100 provided in the present application has a accommodating cavity 11a and an installation port 11b formed in the shell 11, and the mounting plate 2, the annular shell 12, the wireless charging module and the heat dissipation component 5 can be installed in the accommodating cavity 11a through the installation port 11b, so as to provide a certain degree of protection for the mounting plate 2, the annular shell 12, the wireless charging module and the heat dissipation component 5, thereby improving their service life; the wireless charging module is arranged between the cover plate 4 and the mounting plate 2, which can further protect the wireless charging module. The heat dissipation component 5 is arranged in the air cavity 11c to drive the air flow, so that the air flow can enter the air cavity 11c from the annular cavity 11d through the first air port 12a, and then enter the gap space 2b through the air guide port 2a, so that the air flow flows from the surface of the wireless charging module, and finally flows out through the wiring hole 3a through the second air port 4e on the cover plate 4. Of course, the air flow can also enter from the second air port 4e, enter the gap space 2b through the wiring hole 3a, and then enter the air cavity 11c through the air guide port 2a, and finally pass through the first air port 12a on the ring shell 12 through the annular cavity 11d and be discharged from the installation port 11b. In this way, the heat dissipation component 5 can achieve efficient air convection, reduce the situation of heat accumulation in the shell 11, and can quickly dissipate the heat on the wireless charging module, reduce the temperature of the wireless charging module, and keep it in a good temperature environment. In this way, the charging efficiency and service life can be improved. By setting the air flow entry and discharge on the same side, the wireless charger 100 can meet the needs of some specific scenarios, such as wall-mounted or embedded settings, and has strong adaptability.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 The annular cavity 11d is located outside the second air outlet 4e along the inner and outer directions. In this way, the interference between the airflow entering the housing 11 and the airflow discharged from the housing 11 can be reduced, thereby improving the heat dissipation effect.

[0039] It should be noted that the inside-outside direction mentioned here refers to the direction from the inside of the shell 11 to the outside of the shell 11.

[0040] In one embodiment, please refer to Figure 3 and Figure 4 A constricted portion 11e is formed in the shell body 11, and the diameter of the constricted portion 11e is smaller than the diameter of the installation port 11b. The annular shell 12 is arranged on the constricted portion 11e, and the outer peripheral wall of the annular shell 12 is spaced from the cavity wall of the accommodating cavity 11a located between the constricted portion 11e and the installation port 11b to form an annular cavity 11d.

[0041] Here, by providing the constricted portion 11e, a mounting position can be provided for the installation of the annular shell 12, so that the annular shell 12 can be easily installed. By making the diameter of the constricted portion 11e smaller than the diameter of the installation opening 11b, the outer peripheral wall of the annular shell 12 can form an annular cavity 11d with the cavity wall of the accommodating cavity 11a between the constricted portion 11e and the installation opening 11b, so that the airflow can enter or be discharged from the annular side of the housing 11.

[0042] In one embodiment, please refer to Figures 5 to 7 The arrangement direction of the heat dissipation component 5 and the mounting plate 2 is the first direction, the annular shell 12 is arranged to penetrate along the first direction, the inner wall of the annular shell 12 is formed with a flange 12b, the flange 12b is connected to the necking portion 11e, the flange 12b divides the internal space of the annular shell 12 into a first cavity 12c and a second cavity 12d, the first cavity 12c is connected to the second cavity 12d, the mounting plate 2 is arranged on the flange 12b, and a first air outlet 12a is formed on the cavity wall of the second cavity 12d.

[0043] In this way, the airflow can enter the air cavity 11c through the annular cavity 11d located on the ring side through the first air port 12a, and then enter the gap space 2b through the air guide port 2a to dissipate the heat of the wireless charging module located on the mounting plate 2, and finally discharge the mounting port 11b through the wiring hole 3a through the second air port 4e, or dissipate the heat of the wireless charging module along the first direction away from the heat sink through the second air port 4e through the wiring hole 3a, and then dissipate the heat of the part of the wireless charging module located in the gap space 2b through the wiring hole 3a, and finally discharge the mounting port 11b through the air cavity 11c through the first air port 12a and the annular cavity 11d. In this way, not only can the heat dissipation area of ​​the airflow to the wireless charging module be increased, and the heat dissipation effect is better, but also the same-side air intake and exhaust can meet some specific needs, such as the wireless charger 100 can be set against the wall or embedded in some scenes where it is inconvenient for the airflow to enter or be discharged from the side of the shell 11 away from the cover plate 4 along the first direction, and it has strong adaptability.

[0044] For example, in one embodiment, please refer to Figure 6 The flange 12b and the necked portion 11e can be connected by snapping or screwing. For example, the necked portion 11e is formed with a first positioning hole 11e1, and the flange 12b is formed with a second positioning hole 12b1. Then, fasteners such as bolts or screws can be used to pass through the first positioning hole 11e1 and the second positioning hole 12b1 to connect the annular shell 12 and the shell 11, thereby improving the connection strength between the annular shell 12 and the shell 11 and improving the working stability.

[0045] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 There are multiple first air ports 12 a, and the multiple first air ports 12 a are arranged at intervals along the circumferential direction of the annular shell 12 .

[0046] Exemplarily, the number of the first air outlets 12a may be two or more. By arranging a plurality of first air outlets 12a at intervals along the circumference of the ring shell 12, air can be introduced or exhausted along the circumference, increasing the air intake or exhaust volume, thereby increasing the heat dissipation of the wireless charging module, reducing the occurrence of heat accumulation, and increasing the service life of the wireless charging module.

[0047] It should be noted that Figure 1 R1 in the figure may be a first direction, R2 may be a second direction, and R3 may be a third direction. For example, the first direction may be a front-to-back direction, the second direction may be an up-down direction, and the third direction may be a left-to-right direction.

[0048] It should be noted that up refers to the direction toward the ceiling, and down is the opposite of up. The up-down direction, the front-back direction, and the left-right direction are perpendicular to each other and together constitute a three-dimensional vertical coordinate system.

[0049] Exemplarily, in one embodiment, the shape of the mounting plate 2 is not limited. For example, the shape of the mounting plate 2 can be circular when projected along the first direction.

[0050] In one embodiment, please refer to Figures 7 to 11 , the arrangement direction of the heat dissipation component 5 and the mounting plate 2 is the first direction, a portion of the mounting plate 2 is recessed along the first direction toward the heat dissipation component 5 to form a gap groove 2c, a portion of the bottom surface of the gap groove 2c and one side of the gap groove 2c along the second direction are penetrated, a support portion 2d is formed on the bottom surface of the gap groove 2c, the support portion 2d protrudes along the first direction toward away from the heat dissipation component 5, the wireless charging module is supported on the support portion 2d to define a gap space 2b with the gap groove 2c, an air guide port 2a is formed between the support portion 2d and at least one side wall of the gap groove 2c along the third direction, and a wiring hole 3a is formed on the side of the wireless charging module away from the air guide port 2a along the second direction, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0051] In this way, the airflow can enter the gap space 2b through the air guide port 2a to dissipate the heat of the part of the wireless charging module located in the gap space 2b, and dissipate the heat of the wireless charging module through the wiring hole 3a. Alternatively, the airflow can pass through the second air outlet 4e to dissipate the heat of the end face of the wireless charging module away from the mounting plate 2 along the first direction, and dissipate the heat of the end face of the wireless charging module located in the gap space 2b through the wiring hole 3a. Since the wiring hole 3a and the air guide port 2a are arranged along the second direction, the flow path of the airflow can be extended, the heat dissipation effect on the wireless charging module is better, and heat accumulation can be effectively reduced.

[0052] For example, in one embodiment, please refer to Fig.10The support portion 2d can be arranged at the bottom surface of the gap groove 2c at the air guide port 2a, and air guide ports 2a are formed between the support portion 2d and the side walls of the gap groove 2c along the third direction. In this way, the air guide area can be increased and the heat dissipation effect can be better.

[0053] Exemplarily, in one embodiment, the support portion 2d can be formed by stamping a portion of the edge of the air guide port 2a along a first direction away from the heat dissipation assembly 5 to increase the connection strength between the support portion 2d and the mounting plate 2 and improve its supporting performance.

[0054] In one embodiment, please refer to Figures 7 to 10 The wireless charging module includes a circuit board 31 and a coil 32. The circuit board 31 is supported on the support portion 2d to define a gap space 2b with the gap groove 2c. The coil 32 is arranged on a side of the circuit board 31 away from the heat dissipation component 5 along the first direction. The components of the circuit board 31 are arranged on the end surface of the circuit board 31 located in the gap space 2b. A wiring hole 3a is formed on the side of the circuit board 31 away from the air guide port 2a along the second direction. The wire of the coil 32 is electrically connected to the components of the circuit board 31 through the wiring hole 3a.

[0055] In this way, the air flow can enter the gap space 2b through the air guide port 2a to dissipate heat for the components of the circuit board 31 located in the gap space 2b, and dissipate heat for the coil 32 arranged on the circuit board 31 along the first direction away from the heat dissipation component 5 through the wiring hole 3a. Alternatively, the air flow can pass through the second air port 4e to dissipate heat for the coil 32, and dissipate heat for the components located in the gap space 2b through the wiring hole 3a to reduce heat accumulation.

[0056] 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 32 in the wireless charger 100 to charge the battery in the electronic device.

[0057] For example, in one embodiment, please refer to Figure 7 and Figure 8 The wireless charging module includes a baffle 33. The non-recessed portion of the mounting plate 2 is formed with a mounting portion 2e. The baffle 33 is fixedly mounted on the mounting portion 2e to cover the gap groove 2c, so that the mounting plate 2 can be used to limit the movement of the circuit board 31 along the first direction. The baffle 33 is formed with a avoidance opening 33a corresponding to the wiring hole 3a. The coil 32 can be arranged on the side of the baffle 33 away from the circuit board 31 along the first direction. The wire of the coil 32 can be electrically connected to the components of the circuit board 31 through the avoidance opening 33a and the wiring hole 3a. In this way, the baffle 33 can block the coil 32 and the circuit board 31 along the first direction to reduce the heat transfer between the two.

[0058] For example, in one embodiment, please refer to Figures 3 to 7 The flange 12b on the annular shell 12 is formed with a third positioning hole 12e, the mounting portion 2e of the mounting disk 2 is formed with a fourth positioning hole 2e1, and the baffle 33 is formed with a fifth mounting hole. Then, fasteners can be passed through the third positioning hole 12e, the fourth positioning hole 2e1 and the fifth positioning hole 33b to connect the annular shell 12, the mounting disk 2 and the baffle 33, thereby improving the connection strength among the three and achieving good working stability.

[0059] Exemplarily, in one embodiment, there is a distance between the mounting disk 2 and the heat dissipation component 5 along the first direction. This not only reduces the damage to the mounting disk 2 and the circuit board 31 on the mounting disk 2 when the heat dissipation component 5 is driven, but also makes it easier for the heat dissipation component 5 to drive the airflow.

[0060] In one embodiment, please refer to Figure 1 and Figure 2 A charging area 4a corresponding to the wireless charging module is provided on the surface of the cover plate 4, and a plurality of second air outlets 4e are provided at intervals around the circumference of the charging area 4a.

[0061] Exemplarily, the wireless charging module can charge the electronic device located in the charging area 4a.

[0062] In this way, by arranging a plurality of second air vents 4e at circumferential intervals along the charging area 4a on the cover plate 4, the heat can be dissipated to the electronic device along the circumferential direction while the wireless charging module is being cooled, thereby increasing the heat dissipation area of ​​the electronic device, reducing the occurrence of heat accumulation, and increasing the service life of the battery in the electronic device.

[0063] Exemplarily, in one embodiment, the electronic device may be a mobile phone, a tablet, a watch, or a headset, etc.

[0064] Exemplarily, in one embodiment, the shape of the charging area 4a is not limited, for example, it can be circular or square, etc.

[0065] Exemplarily, in one embodiment, the shape of the housing 11 is not limited. For example, the projection of the housing 11 along the first direction may be circular.

[0066] Exemplarily, in one embodiment, the shape of the second air outlet 4e is not limited. For example, in the projection along the first direction, the shape of the second air outlet 4e can be a long strip.

[0067] In one embodiment, please refer to Figure 1 and Figure 2 The portion of the cover plate 4 where the charging area 4a and the second air outlet 4e are provided is a heat dissipation area 4b, and the heat dissipation area 4b is recessed along the first direction toward the direction close to the wireless charging module to form a groove 4c.

[0068] Here, by recessing the heat dissipation area 4b along the first direction toward the wireless charging module to form a groove 4c, the gap between the electronic device and the heat dissipation area 4b 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.

[0069] In one embodiment, please refer to Figure 1 and Figure 2 The cover plate 4 is formed with a guide groove 4d, which is located outside the heat dissipation area 4b. The opening direction of the guide groove 4d is set along the first direction away from the wireless charging component, and the guide groove 4d is connected to the groove 4c.

[0070] Exemplarily, the second air outlet 4e can be located between the charging area 4a and the guide groove 4d along the radial direction of the mounting plate 2. Here, by connecting the guide groove 4d with the groove 4c, on the one hand, the airflow of the second air outlet 4e in the groove 4c can dissipate heat for the electronic device through the guide groove 4d, 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 5 can be dissipated more quickly through the guide groove 4d and the second air outlet 4e, reducing the occurrence of heat accumulation in the housing 11.

[0071] Exemplarily, in one embodiment, the shape of the guide groove 4d is not limited. For example, along the projection of the first direction, the shape of the guide groove 4d can be a parallelogram.

[0072] In one embodiment, there are multiple guide grooves 4d, and the multiple guide grooves 4d are arranged at intervals along the circumference of the heat dissipation area 4b.

[0073] For example, the number of the guide grooves 4d may be three, and the three guide grooves 4d may be arranged at intervals of 120° along the circumference of the heat dissipation area 4b. In this way, the heat dissipation effect of the wireless charging module and the electronic device may be further improved.

[0074] Exemplarily, in one embodiment, the wireless charger 100 includes a magnet, which can be arranged around the periphery of the wireless charging module. A connection area 4f is formed on the cover plate 4 at a position corresponding to the magnet. The connection area 4f is arranged around the periphery of the heat dissipation area 4b. The connection area 4f is formed with a guide groove 4d. A magnet or iron sheet is arranged in the electronic device, so that the electronic device can be stably attracted.

[0075] In one embodiment, please refer to Figure 4 The heat dissipation assembly 5 includes a wind wheel 51 , a driving member 52 and a mounting member 53 . The mounting member 53 is arranged on the cavity wall of the air cavity 11 c , and the driving member 52 is arranged on the mounting member 53 . The driving member 52 is used to drive the wind wheel 51 .

[0076] Exemplarily, the mounting member 53 can be mounted to the cavity wall of the air cavity 11c away from the mounting plate 2 along the first direction by fasteners such as screws or bolts, and the driving member 52 can be fixed on the mounting member 53 by fasteners such as screws or bolts. The driving shaft of the driving member 52 can be connected to the wind wheel 51. The driving member 52 drives the wind wheel 51 to rotate to achieve more efficient air convection, so that the coil 32 and the circuit board 31 can quickly dissipate heat.
