DETAILED DESCRIPTION

[0035] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0036] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. 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.

[0037] The present application embodiment provides a wireless charger. Figures 1 to 10 The wireless charger 100 includes a housing 1, a mounting plate 2, a wireless charging component 3, a panel 4 and a heat sink 5. The housing 1 is formed with a receiving space 1a and a first air outlet 1b and a mounting port 1c connected to the receiving space 1a. The mounting plate 2 is arranged in the receiving space 1a to define an inner cavity 1a1 in the receiving space 1a. The mounting plate 2 is formed with an air guide port 2a. The inner cavity 1a1 is connected with the first air outlet 1b and the air guide port 2a. The wireless charging component 3 is arranged on the mounting plate 2. A gap space 2b is formed between the wireless charging component 3 and the mounting plate 2. The wireless charging component 3 is formed with a wiring hole 3a. The gap space 2b is connected with the wiring hole 3a and the air guide port 2a. The panel 4 is arranged on the wireless charging component 3. The panel 4 is formed with a second air outlet 4a that penetrates. The second air outlet 4a is connected with the wiring hole 3a and the mounting port 1c. The heat sink 5 is arranged in the inner cavity 1a1. The heat sink 5 is used to drive the gas flow in the inner cavity 1a1 to dissipate heat from the wireless charging component 3.

[0038] The wireless charger 100 provided in the present application has a accommodating space 1a and an installation port 1c formed in the shell 1. The mounting plate 2, the wireless charging component 3 and the heat sink 5 can be installed in the accommodating space 1a through the installation port 1c, so as to provide a certain degree of protection for the mounting plate 2, the wireless charging component 3 and the heat sink 5 and improve their service life; the wireless charging component 3 is arranged between the panel 4 and the mounting plate 2, which can further protect the wireless charging component 3. The heat sink 5 is arranged in the inner cavity 1a1 to drive the airflow, so that the airflow can enter the inner cavity 1a1 from the first air port 1b, and then enter the gap space 2b through the air guide port 2a, so that the airflow flows from the surface of the wireless charging component 3, and finally flows out through the wiring hole 3a and the second air port 4a on the panel 4. Of course, the airflow can also enter from the second air port 4a, enter the gap space 2b through the wiring hole 3a, and then enter the inner cavity 1a1 through the air guide 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 5, and the occurrence of heat accumulation in the outer shell 1 can be reduced. The heat on the wireless charging component 3 can be dissipated more quickly, and the temperature of the wireless charging component 3 can be reduced to keep it in a good temperature environment. In this way, the charging efficiency and service life can be improved.

[0039] Exemplarily, in one embodiment, the mounting plate 2 and the housing 1 may be connected by snap-fitting or screw-fitting.

[0040] In one embodiment, please refer to Figure 1 and 2The mounting port 1c and the first air outlet 1b are arranged in a first direction, the inner cavity 1a1 is located on a side of the mounting plate 2 away from the mounting port 1c along the first direction, the wireless charging component 3 is arranged on a side of the mounting plate 2 away from the inner cavity 1a1 along the first direction, and the panel 4 is arranged on a side of the wireless charging component 3 close to the mounting port 1c along the first direction.

[0041] That is to say, the first air outlet 1b, the inner cavity 1a1, the mounting plate 2, the wireless charging assembly 3 and the panel 4 are arranged in sequence along the first direction. After the heat sink 5 is working, the airflow can be driven to enter the inner cavity 1a1 from the first air outlet 1b, and then enter the gap space 2b through the air guide port 2a, and finally flow out from the second air outlet 4a on the panel 4 through the wiring hole 3a. Alternatively, the airflow can also enter from the second air outlet 4a, enter the gap space 2b through the wiring hole 3a, and then enter the inner cavity 1a1 through the air guide port 2a, and finally flow out from the first air outlet 1b on the outer casing 1. In this way, the flow path of the airflow can be shortened, the heat can be dissipated faster, and the heat dissipation efficiency is high.

[0042] It should be noted that Figure 1 R1 may be the first direction, R2 may be the second direction, and R3 may be the third direction.

[0043] 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.

[0044] Exemplarily, in one embodiment, the second direction and the third direction may both be radial directions of the mounting plate 2 , 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.

[0045] 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.

[0046] In one embodiment, please refer to Figure 5 A charging area 4b corresponding to the wireless charging component 3 is disposed on the surface of the panel 4, and a plurality of second air outlets 4a are provided, and the plurality of second air outlets 4a are disposed at circumferential intervals around the charging area 4b.

[0047] Exemplarily, the wireless charging component 3 can charge the electronic device located in the charging area 4b.

[0048] In this way, by arranging a plurality of second air vents 4a at circumferential intervals along the charging area 4b on the panel 4, while dissipating heat for the wireless charging component 3, heat can also be dissipated circumferentially for the electronic device, thereby increasing the heat dissipation area of ​​the electronic device, reducing heat accumulation, and increasing the service life of the battery in the electronic device.

[0049] It should be noted that the circumferential direction of the charging area 4b may be a direction that rotates around the first direction as an axis.

[0050] Exemplarily, in one embodiment, the electronic device may be a mobile phone, a tablet, a watch, or a headset, etc.

[0051] Exemplarily, in one embodiment, the shape of the charging area 4b is not limited, for example, it can be circular or square, etc.

[0052] 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.

[0053] Exemplarily, in one embodiment, the shape of the second air outlet 4a is not limited. For example, in the projection along the first direction, the shape of the second air outlet 4a can be a long strip.

[0054] In one embodiment, please refer to Figure 5 The portion of the panel 4 where the charging area 4b and the second air outlet 4a are provided is a heat dissipation area 4c, and the heat dissipation area 4c is recessed along the first direction toward the direction close to the wireless charging component 3 to form a groove 4d.

[0055] Here, by recessing the heat dissipation area 4c along the first direction toward the direction close to the wireless charging component 3 to form a groove 4d, the gap between the electronic device and the heat dissipation area 4c 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.

[0056] In one embodiment, please refer to Figure 5 The panel 4 is formed with a heat dissipation groove 4e, which is located outside the heat dissipation area 4c. The opening direction of the heat dissipation groove 4e is set along the first direction away from the wireless charging component 3, and the heat dissipation groove 4e is connected to the groove 4d.

[0057] Exemplarily, the second air outlet 4a can be located between the charging area 4b and the heat dissipation groove 4e along the radial direction of the mounting plate 2. Here, by connecting the heat dissipation groove 4e with the groove 4d, on the one hand, the airflow of the second air outlet 4a in the groove 4d can dissipate the heat of the electronic device through the heat dissipation groove 4e, further increasing the heat dissipation area of ​​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 4e and the second air outlet 4a, reducing the occurrence of heat accumulation in the housing 1.

[0058] Exemplarily, in one embodiment, the shape of the heat dissipation slot 4e is not limited. For example, along the projection of the first direction, the shape of the heat dissipation slot 4e may be a parallelogram.

[0059] In one embodiment, please refer to Figure 5There are multiple heat dissipation grooves 4e, and the multiple heat dissipation grooves 4e are arranged at intervals along the circumference of the heat dissipation area 4c.

[0060] For example, the number of the heat dissipation grooves 4e can be three, and the three heat dissipation grooves 4e can be arranged at intervals of 120° along the circumference of the heat dissipation area 4c. In this way, the heat dissipation effect of the wireless charging component 3 and the electronic device can be further improved.

[0061] For example, in one embodiment, please refer to Figure 5 The wireless charger 100 includes a magnet, which can be arranged around the periphery of the wireless charging component. A connection area 4f is formed on the panel 4 at a position corresponding to the magnet. The connection area 4f is arranged around the periphery of the heat dissipation area 4c. The connection area 4f is formed with a heat dissipation groove 4e. A magnet or iron sheet is arranged in the electronic device, so that the electronic device can be stably attracted.

[0062] In one embodiment, please refer to Figure 8 , Fig. 9 and Fig.10 , the arrangement direction of the mounting port 1c and the first air outlet 1b is the first direction, a portion of the mounting plate 2 is recessed along the first direction toward the heat sink 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 away from the heat sink 5, the wireless charging component 3 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 component 3 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.

[0063] In this way, the airflow can enter the gap space 2b through the air guide port 2a to dissipate the heat of the portion of the wireless charging component 3 located in the gap space 2b, and dissipate the heat of the wireless charging component 3 through the wiring hole 3a. Alternatively, the airflow can pass through the second air outlet 4a to dissipate the heat of the end surface of the wireless charging component 3 that is away from the mounting plate 2 along the first direction, and dissipate the heat of the end surface of the wireless charging component 3 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 component 3 is better, and heat accumulation can be effectively reduced.

[0064] For example, in one embodiment, please refer to Figure 8 , Fig. 9 and 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.

[0065] 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 sink 5 to increase the connection strength between the support portion 2d and the mounting plate 2 and improve its supporting performance.

[0066] In one embodiment, please refer to Figure 6 , Figure 7 , Figure 8 and Fig. 9 The wireless charging component 3 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 sink 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.

[0067] 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 sink 5 through the wiring hole 3a. Alternatively, the air flow can pass through the second air port 4a 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.

[0068] 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.

[0069] For example, in one embodiment, please refer to Figure 6 and Figure 7The wireless charging assembly 3 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 as to cooperate with the mounting plate 2 to limit the movement of the circuit board 31 along the first direction. The baffle 33 is formed with an 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.

[0070] For example, in one embodiment, please refer to Figure 7 The connection method between the baffle plate 33 and the mounting portion 2e can be snap-on or screw-on. For example, a first positioning hole 33b is formed on the baffle plate 33, and a second positioning hole 2e1 is formed on the mounting portion 2e. Fasteners such as screws or bolts can be used to pass through the first positioning hole 33b and the second positioning hole 2e1 to improve the connection strength between the baffle plate 33 and the mounting plate 2, and the working stability is good.

[0071] Exemplarily, in one embodiment, there is a distance between the mounting disk 2 and the heat sink 5 along the first direction. This not only reduces the damage of the heat sink 5 to the mounting disk 2 and the circuit board 31 on the mounting disk 2 when being driven, but also makes it easier for the heat sink 5 to drive the airflow.

[0072] In one embodiment, please refer to Figure 2 and Figure 3 The heat sink 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 inner cavity 1a1. The mounting member 53 has a third air port 53a that passes through along the first direction. The third air port 53a is connected to the first air port 1b. The driving member 52 is arranged on the mounting member 53, and the driving member 52 is used to drive the wind wheel 51.

[0073] Exemplarily, the mounting member 53 can be mounted on the cavity wall of the inner cavity 1a1 away from the mounting plate 2 along the first direction by fasteners such as screws or bolts, and the mounting member 53 is formed with a third air port 53a penetrating along the first direction, and the third air port 53a is connected to the first air port 1b, so that the airflow can enter the inner cavity 1a1 through the first air port 1b and the third air port 53a or be discharged from the inner cavity 1a1 through the first air port 1b and the third air port 53a. The driving member 52 can be fixedly arranged on the mounting member 53 by fasteners such as screws or bolts, and 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.

[0074] For example, in one embodiment, please refer to Figure 3 and Figure 4 The shapes of the first air outlet 1b and the third air outlet 53a are not limited. For example, the projection shape of the first air outlet 1b and the third air outlet 53a along the first direction can be a curved long strip.

[0075] In one embodiment, please refer to Figure 3 and Figure 4 The number of the third air outlets 53a and the number of the first air outlets 1b are both multiple, and the multiple third air outlets 53a are arranged at intervals along the circumference of the wind wheel 51. The first air outlet 1b and the third air outlets 53a are arranged correspondingly, and each third air outlet 53a is connected to the corresponding first air outlet 1b.

[0076] For example, the number of the third air ports 53a and the number of the first air ports 1b can be three, and the three third air ports 53a are arranged at intervals of 120° along the circumference of the wind wheel 51, and the three first air ports 1b are arranged correspondingly, so that the three first air ports 1b and the three third air ports 53a are respectively roughly arranged to form an annular area. In this way, the airflow can be further accelerated.

[0077] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The wireless charger 100 includes a support rod 7, a ball head 7a is formed at one end of the support rod 7, a rotating portion 1a2 is provided in an inner cavity 1a1, a rotating cavity 1a21 is formed in the rotating portion 1a2, and the ball head 7a is rotatably arranged in the rotating cavity 1a21.

[0078] Exemplarily, the rotating portion 1a2 can be arranged on the cavity wall of the inner cavity 1a1 away from the mounting member 53 along the first direction. By forming a rotating cavity 1a21 in the rotating portion 1a2, the ball head 7a can rotate in the rotating cavity 1a21. In this way, on the one hand, the ball head 7a located in the rotating cavity 1a21 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 7a and the rotating cavity 1a21, 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.
