Referring to fig. 1 and fig. 2, an embodiment of the present application provides a wireless charging cradle 10 for charging an electronic device 20, where the electronic device 20 may be a mobile phone or a tablet computer, and is not limited herein. The type of the electronic device 20 is not limited herein as long as the electronic device 20 has a wireless charging function, that is, the electronic device 20 has at least a receiving coil 20a built therein.
The wireless charging stand 10 includes a heat sink 100 and a wireless charging module 200, wherein the wireless charging module 200 is detachably connected to the heat sink 100, that is, the wireless charging module 200 can be connected to the heat sink 100, or can be detached from the heat sink 100 to separately charge the electronic device 20. The wireless charging module 200 can be connected to a plug or an adapter through a wire 201 to connect with a power supply, so as to satisfy the requirement of wirelessly charging the electronic device 20.
As shown in fig. 1 and fig. 2, the heat sink 100 includes a base 110 and a heat sink module 120. The heat dissipation module 120 is connected to the base 110, when the wireless charging module 200 is connected to the heat dissipation base 100, the heat dissipation module 120 is electrically connected to the wireless charging module 200, and the heat dissipation module 120 is configured to dissipate heat of the wireless charging module 200 under power supply of the wireless charging module 200, so that the wireless charging module 200 can improve charging of the electronic device 20 as much as possible, and improve charging efficiency.
When the wireless charging module 200 is separated from the heat sink 100, the wireless charging module 200 disconnects the power supply to the heat sink 120.
It should be noted that, after the wireless charging module 200 disconnects the power supply to the heat dissipation module 120, the wireless charging module 200 can still charge the electronic device 20, which is favorable for the charging requirement of the electronic device 20 in the use process, that is, when the user can use the electronic device 20, the wireless charging module 200 can charge the electronic device 20, and with this structure, the cumbersome heat dissipation seat 100 does not need to be carried, so as to improve the portability and improve the user experience.
The wireless charging module 200 is detachably connected to at least one of the base 110 and the heat dissipating module 120, so that the wireless charging module 200 is detachably connected to the heat dissipating base 100. The separable connection of the two includes but is not limited to magnetic attraction or vacuum adsorption. For example, referring to fig. 8, the wireless charging module 200 is detachably connected to the base 110 through a magnet 202 or a suction cup. Alternatively, the wireless charging module 200 may be detachably connected to the heat sink 100 through a magnet 202 or a suction cup.
As shown in fig. 1 and 4, the heat dissipation module 120 includes a fan 121 and a casing 122, and the fan 121 is disposed in the casing 122. The casing 122 has a first electrical connection portion 123 electrically connected to the fan 121, and when the wireless charging module 200 is connected to the heat sink 100, the first electrical connection portion 123 is electrically connected to the wireless charging module 200, so that the wireless charging dock 10 can complete the functions of charging and dissipating heat of the electronic device 20 with only one plug or adapter, and does not need to separately configure a plug or adapter for the fan 121.
The first electrical connection portion 123 includes a first electrode 123a and a second electrode 123b, the second electrode 123b is an annular electrode, and is disposed around the first electrode 123a by taking the center of the first electrode 123a as a circular point, so that the wireless charging module 200 can be electrically connected to the first electrical connection portion 123 at multiple angles to supply power to the fan 121.
The heat sink 100 is formed with a drainage duct, and when the fan 121 operates, air flows through the drainage duct and takes away heat of the wireless charging module 200.
It should be noted that the air guiding duct may be formed in the housing 122 or the base 110, and only when the fan 121 works, the air flows through the air guiding duct and takes away the heat of the wireless charging module 200. In some embodiments, the air guide duct may also be formed by the housing cover 122 and the seat body 110.
In some embodiments, as shown in fig. 3 to 5, the housing 122 is connected to the base 110. For example, the cover 122 is connected to the base 110 by glue, or the cover 122 is connected to the base 110 by fasteners such as snaps and screws. For another example, the cover 122 and the base 110 are connected by a detachable connection structure such as a snap connection or a magnetic connection, so that the cover 122 and the fan can be detached from the base 110, which is convenient for maintenance, and the heat dissipation module 120 can be used as an independent module for heat dissipation of other devices such as a tablet computer and a mobile phone, so as to widen the application scene of the heat dissipation module 120. The base 110 has a receiving groove 111, a first opening 110a is disposed on a bottom wall of the receiving groove 111, the heat dissipation module 120 is disposed in the receiving groove 111, and the fan 121 is opposite to the first opening 110 a.
A second air opening 122a is formed in the casing 122 at a position corresponding to the circumferential side of the fan 121, the air guide surface 112 is formed at least in part of the side wall of the accommodating groove 111, and the air guide surface 112 and the second air opening 122a together form a flow guide duct.
It should be noted that the air guide surface 112 and the second air opening 122a form a flow guide air duct together, and only a part of the air guide surface 112 is required to be opposite to the second air opening 122 a. Specifically, the air guide surface 112 may be only partially opposed to the second air opening 112a, or may be entirely opposed to the second air opening 112 a. For example, the sidewall of the accommodating groove 111 corresponding to the second air opening 112a forms the air guiding surface 112, and the entire structure of the air guiding surface 112 is opposite to the second air opening 112 a. For another example, only a portion of the sidewall of the accommodating groove 111 forming the air guiding surface 112 faces the second air inlet 112a, and only a portion of the air guiding surface 112 faces the second air inlet 112 a.
Understandably, the side wall of the receiving groove 111 forming the air guide surface 112 is spaced from the housing 122 to provide a drainage effect. For example, in some embodiments, all the side walls of the accommodating groove 111 are spaced from the casing 122, and at least some of the side walls form the wind guide surface 112. In other embodiments, a part of the side wall of the receiving groove 111 is spaced apart from the casing 122 to form the wind guide surface 112. In another embodiment, a part of the side wall of the housing groove 111 is provided at a distance from the casing 122, and only a part of the side wall provided at a distance from the casing 122 forms the air guide surface 112. The forming position of the air guide surface 112 is not limited herein, and it is only necessary that the air guide surface 112 and the second air opening 112a form a flow guide duct together, and the fan 121 can perform the function of guiding air flow to accelerate heat dissipation efficiency when operating.
With reference to fig. 3 to fig. 5, 2 second air openings 122a are formed in the casing 122, the 2 second air openings 122a are respectively located at two opposite sides of the casing 122, and the accommodating groove 111 penetrates at least one side of the seat 110 along an extending direction of the air guiding surface 112, wherein the extending direction of the air guiding surface 112 is perpendicular to an axial direction of the fan 121. Since the accommodating groove 111 penetrates the base 110 along the extending direction of the air guide surface 112, when the fan 121 operates, the airflow can dissipate heat of the wireless charging module 200 or the electronic device 20 along the air guide surface 112 to a greater extent, thereby improving the heat dissipation efficiency.
It should be noted that one of the first tuyere 110a and the second tuyere 122a is used for air intake, and the other is used for air outtake. The first tuyere 110a is used for air intake, and the second tuyere 122a is used for air intake, which is not limited herein. For example, in some embodiments, as shown in fig. 6, when the fan 121 is operated, the air flow enters the casing 122 from the first air opening 110a and flows out of the casing 122 from the second air opening 122a, so as to blow air to the wireless charging module 200 and/or the electronic device 20 under the guidance of the air guiding surface 112, so as to remove heat and achieve heat dissipation. For another example, in another embodiment, as shown in fig. 7, when the fan 121 is operated, the air flow enters the casing 122 from the second air opening 122a along the air guiding surface 112 and is exhausted from the first air opening 110a, so as to remove heat and achieve heat dissipation.
As shown in fig. 6 to 8, in some embodiments, the wireless charging module 200 includes a housing 210, a charging element 220, and an electrical connection element 230, wherein the electrical connection element 230 is electrically connected to the charging element 220, a portion of the electrical connection element 230 is exposed to the housing 210 to form a second electrical connection portion, and when the wireless charging module 200 is connected to the heat sink 100, the heat dissipation module 120 is electrically contacted with the second electrical connection portion, so that the charging element 220 can supply power to the heat dissipation module 120.
Further, as shown in fig. 8 and 9, the second electrical connection portion includes a third electrode 230a and a fourth electrode, the fourth electrode 230b is an annular electrode, and is disposed around the third electrode 230a by taking the center of the third electrode 230a as a circular point, so that the wireless charging module 200 can be electrically connected to the first electrical connection portion 123 at multiple angles to supply power to the fan 121.
The overall shape of the wireless charging module 200 may be a rectangular block shape, or may be another shape, for example, as shown in fig. 9, the wireless charging module 200 is a disk shape as a whole. The shape of the wireless charging module 200 is not limited herein.
The charging assembly 220 is disposed in the housing 210, in some embodiments, the charging assembly 220 includes a transmitting coil 220a, a magnetic shielding sheet 220b and a circuit board 220c, the transmitting coil 220a and the circuit board 220c are respectively located on two sides of the magnetic shielding sheet 220b, and the magnetic shielding sheet 220b may be ferrite, so as to achieve a good magnetic shielding effect and prevent wireless waves emitted by the transmitting coil 220a from generating signal interference on the circuit board 220 c.
Referring to fig. 10 and 11, the housing 110 includes a base 1101 and a supporting base 1102, the heat dissipation module 120 is disposed on the supporting base 1102, the supporting base 1102 is connected to the base 1101, and the supporting base 1102 is used to place the electronic device 20 in an inclined manner with respect to the base 1101, so that the housing 110 can be used as a support to support the electronic device 20 in an inclined manner.
It should be noted that there are many possibilities for the connection structure between the supporting base 1102 and the base 1101. For example, as shown in connection with FIG. 10, in some embodiments, the support base 1102 is fixedly connected to the base 1101 and is at an acute angle to each other.
In other embodiments, as shown in FIG. 11, the support 1102 is pivotally coupled to the base 1101, for example, the support 1102 is pivotally coupled to the base 1101 by a pivot 1103. Because the supporting base 1102 is rotatably connected with the base 1101, the angle of the supporting base 1102 relative to the base 1101 can be adjusted to meet the supporting requirements of different inclined angles of the electronic device 20.
Further, the base 1101 is provided with a clearance groove 1104, and the supporting base 1102 can be rotatably folded into the clearance groove 1104, so that the supporting base is convenient to store and carry. The clearance groove 1104 may be provided in the support 1102, and when the support 1102 is rotated and folded with respect to the base 1101, the clearance groove 1104 may accommodate the base 1101, thereby improving portability of the seat body 110.
