Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging, and particularly to a wireless charging device. Background Art

[0002] With the progress of electronic industrial technology and the rapid evolution of semiconductor manufacturing processes, the functions of portable electronic devices have become increasingly diverse and complex. At the same time, the overall structure is thin, light, short, and small, making it very convenient to carry around. In particular, mobile phones not only combine voice call and data transmission functions, but also can access the Internet wirelessly and connect to social networks anytime and anywhere via the commonly established wireless communication or local area network channels. Therefore, almost everyone has a mobile phone.

[0003] However, the built-in battery of portable electronic devices has limited power and must be charged frequently, such as at least once a day. Moreover, the uploading and downloading of a large amount of audio and video data have further increased the power consumption significantly. To solve the inconvenience of charging, in the conventional technology, a wireless charging solution has been provided. A mobile phone only needs to be equipped with a wireless charging receiving module connected to a charging module, and it can obtain the power required for charging by approaching or attaching to a wireless charging board with a wireless charging transmitting module. Among them, the wireless charging receiving module and the wireless charging transmitting module transmit power through the magnetic field interaction between the receiving coil and the transmitting coil.

[0004] Generally speaking, the wireless charging transmitting module includes a transmitting coil and a transmitting-end power conversion controller, and the wireless charging receiving module includes a receiving coil and a receiving-end power conversion controller. Among them, the transmitting-end power conversion controller receives an input power supply, such as a USB power supply or a DC power supply from an adapter, converts it into a transmitting-end AC power supply, and then drives the transmitting coil to generate a magnetic field. The receiving coil generates a receiving-end AC power supply by induction, and then the receiving-end AC power supply is received and converted into a DC output power supply by the receiving-end power conversion controller.

[0005] Existing wireless charging devices are all of a closed structure. To achieve portability, heat is likely to accumulate in the wireless charging device during operation. When it is in a high-temperature environment for a long time, it is likely to cause damage to the inductance components inside the wireless charging device. In addition, the closed structure is not conducive to heat dissipation. Summary of the Invention

[0006] The purpose of the present invention is to provide a wireless charging device to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0008] The present invention is a wireless charging device, including:

[0009] A control unit, including an upper shell assembly, a circuit board, and a fan installed in the upper shell assembly;

[0010] The upper shell assembly is provided with an air outlet groove;

[0011] A charging part, the lower shell assembly and a charging coil installed in the lower shell assembly;

[0012] The lower shell assembly is provided with an air inlet groove;

[0013] The upper shell assembly and the lower shell assembly are connected by a cylinder, and the upper shell assembly and the lower shell assembly are communicated through the cylinder;

[0014] The control part and the charging part are connected by a cylinder. Both the control part and the charging part are disc structures. The charging part rotates around the cylinder. When the control part and the charging part overlap, they are not communicated. By rotating the charging part, the through groove of the charging part and the cylinder is communicated, so as to realize the communication between the inside of the charging part and the cylinder;

[0015] When the fan works, the fan distributes the air inside the control part through the air outlet groove, the external air enters the charging part through the air inlet groove, and then enters the control part through the cylinder, and the heat dissipation of the inside of the control part and the inside of the charging part is completed through the flowing air.

[0016] Further, the upper shell assembly includes an upper shell body and an upper cover body. The upper cover body is cooperatively installed on the opening of the upper shell body. The upper shell body is a disc structure. A plurality of threaded seats are provided on the inner bottom surface of the upper shell body. A circuit board is provided inside the upper shell body, and the circuit board is installed on the threaded seat by screws;

[0017] The circuit board is a ring structure. There is a gap between the circuit board and the bottom surface of the upper shell body. There is a gap between the inner wall of the upper shell body and the outer side edge of the circuit board. The inside of the cylinder is communicated with the inside of the upper shell body, which is convenient for air to flow through the surface of the circuit board and for heat dissipation.

[0018] Further, at least one conductive end is provided on the circuit board. The conductive end is electrically connected to the charging coil through a conductive member. A key is provided on the circuit board, and a button corresponding to the key is provided on the upper cover body;

[0019] The power supply circuit of the fan is connected by triggering the key through the button.

[0020] Further, a convex ring is provided in the middle of the inner bottom surface of the upper shell body. A ring groove is formed between the convex ring and the inner wall of the upper shell body. The inside of the convex ring and the ring groove are communicated through a through groove. A fan is installed inside the convex ring, and the fan and the air outlet groove on the upper cover body are correspondingly distributed;

[0021] The port of the convex ring fits against the side surface of the upper cover body, thereby forming a sealed cavity. The sealed cavity is connected to the formed annular groove through a through groove, so as to realize the air flow in the formed annular groove into the sealed cavity. Since the through grooves are annularly distributed, it is convenient to realize the entry of the air environment into the sealed cavity.

[0022] Further, the lower shell assembly includes a lower shell body and a lower cover body. The lower cover body is fitted and installed on the opening of the lower shell body. On the inner bottom surface of the lower shell body, there are convex blocks and an annular seat. A sleeve body is fitted and installed in the annular seat. A slot hole communicating with the inside of the sleeve body is opened on the side surface of the annular seat. On the lower cover body, there are a first round hole and a second round hole. The first round hole corresponds to the annular seat, and the second round hole corresponds to the convex block. A charging coil is installed in the second round hole, and the charging coil is located on the convex block. An air inlet groove is opened on the side surface of the lower shell body, and the air inlet groove is communicated with the slot hole;

[0023] The charging coil is placed on the convex block, so that there is a gap between the charging coil and the inner bottom surface of the lower shell body, which is convenient for realizing the air flow through the bottom surface of the charging coil. The electronic device is placed on the charging coil, thereby realizing wireless charging.

[0024] Further, the annular seat and the sleeve body inside the annular seat are sleeved on the outside of the column body. A base is installed at the bottom end of the column body, and support legs are installed on the bottom surface of the upper shell body.

[0025] Further, a charging part is installed on the column body. The column body includes a plate body and a tube body. The tube body is installed at the bottom of the plate body. A first through groove and a second through groove are opened on the outer side surface of the tube body. The central angle formed between the first through groove and the second through groove is 180°. The upper shell assembly is communicated with the inside of the tube body through the first through groove. When the angle formed between the charging part and the control part is 180°, the slot hole is communicated with the second through groove;

[0026] Thus, when the control part and the charging part overlap, they are not communicated with each other. By rotating the charging part by 180°, the control part and the charging part are communicated with each other. The external air enters the charging part through the air inlet groove, and then enters the control part through the column body, and the internal parts of the control part and the charging part are cooled by the flowing air.

[0027] Further, two charging parts are installed on the column body. The column body includes a plate body and a tube body. The tube body is installed at the bottom of the plate body. A first through groove, a second through groove and a third through groove are opened on the outer side surface of the tube body. The angle formed between the second through groove and the third through groove is 120°, and the control part and the two charging parts are equidistantly distributed around the column body.

[0028] Further, a groove is provided on one side of the lower housing. A plurality of air inlet grooves are formed on the outer side surface of the groove. The groove is snap-fitted on the outside of the support leg. The opening directions of the grooves provided on the two lower housings are opposite.

[0029] When the control part and the two charging parts overlap, they are not connected. By rotating the two charging parts 120° in the reverse direction, the control part and the charging parts are connected through the column. External air enters the charging part through the air inlet groove, and then enters the control part through the column. The internal parts of the control part and the charging part are cooled by the flowing air.

[0030] The present invention has the following beneficial effects:

[0031] When the fan works in the present invention, the fan distributes the air inside the control part through the air outlet groove. External air enters the charging part through the air inlet groove, and then enters the control part through the column. The internal parts of the control part and the charging part are cooled by the flowing air.

[0032] The charging coil of the present invention is placed on the bump, so that there is a gap between the charging coil and the inner bottom surface of the lower housing, which is convenient for air to flow through the bottom surface of the charging coil. The electronic device is placed on the charging coil to achieve wireless charging.

[0033] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] A convex ring 101 is provided in the middle of the inner bottom surface of the upper shell body 1. A ring groove is formed between the convex ring 101 and the inner wall of the upper shell body 1. The inside of the convex ring 101 and the ring groove are communicated through a through groove 102. A fan 6 is installed inside the convex ring 101, and the fan 6 and the air outlet groove 201 on the upper cover body 2 are correspondingly distributed;

[0063] The port of the convex ring 101 fits against the side surface of the upper cover body 2, thereby forming a sealed cavity. The sealed cavity is connected to the formed annular groove through the through groove 102, so as to realize the air flow in the formed annular groove into the sealed cavity.

The first round hole 801 corresponds to the annular seat 705, and the second round hole 802 corresponds to the convex block 703. A charging coil 9 is installed in the second round hole 802. The charging coil 9 is located on the convex block 703. An air inlet groove 702 is opened on the side surface of the lower shell 7. The air inlet groove 702 is communicated with the slot hole 706;

[0065] The charging coil 9 is placed on the convex block 703, so that there is a gap between the charging coil 9 and the inner bottom surface of the lower shell 7, which is convenient for air to flow through the bottom surface of the charging coil 9.

[0073] By using a single circuit board 3 and two charging coils 9, charging of two electronic devices is realized.

[0074] When the control part and the two charging parts overlap, they are not connected. By rotating the two charging parts counterclockwise by 120°, connection between the control part and the charging parts through the column body 10 is realized. External air enters the charging part through the air inlet groove 702, then enters the control part through the column body 10, and heat dissipation of the interiors of the control part and the charging part is completed through the flowing air.

[0075] After the control part and the two charging parts overlap, folding is completed, which is convenient for storage.
