Description

Technical Field

[0001] The present invention relates to a multifunctional wireless charger. Background Art

[0002] Wireless charging technology is becoming increasingly mature at present. Most wireless charging products on the market follow the QI protocol standard formulated by the WPC Alliance. Currently, the maximum power supported by the QI protocol for wireless charging is 15W, and the heat generated by its 15W products is not so serious. Currently, 40W wireless fast charging products have emerged on the market. Since they are high-power wireless fast charging devices, a large amount of heat will be generated during the charging process. As the heat increases, the charging efficiency will decrease.

[0045] A support 24 is provided on the bearing surface for supporting the mobile phone and creating a gap between the mobile phone and the bearing surface that does not affect wireless charging; the gap is a heat dissipation air duct 21; the air outlet 12 on the base 1 corresponds to the heat dissipation air duct 21. Support bodies 24 are symmetrically arranged on the left and right sides of the bearing surface of the heat dissipation air duct 21. Of course, if necessary, multiple support bodies 24 can be provided on the bearing surface as needed.

[0046] A second wireless charging module 7 for charging wireless charging products placed on the base 1 is provided in the installation cavity 11 of the base 1; a control module 6 is also provided in the installation cavity 11; the control module 6 includes a PCBA 61 and a type-c interface 62; the first wireless charging module 5, the second wireless charging module 7, the type-c interface 62, and the blower 3 are all electrically connected to the PCBA 61. The type-c interface 62 is used to connect to an external power source, and the PCBA 61 is used to control the operation of the first wireless charging module 5, the second wireless charging module 7, and the blower 3. The PCBA 61 is a PCB board with control components; the blower 3 is arranged below the PCBA 61; the first wireless charging module 5 is arranged above the PCBA 61; both the first wireless charging module 5 and the second wireless charging module 7 are existing wireless charging modules, mainly coils arranged on ferrite. The technical principles and installation structures for the PCBA 61 to control the first wireless charging module 5, the second wireless charging module 7, and the blower 3 are well-known to those skilled in the art, so they will not be repeated here.

[0047] A plurality of obstacle columns 22 distributed in a rectangular shape and used to change the wind direction are provided in the heat dissipation air duct 21 on the bearing surface; each obstacle column 22 is correspondingly arranged at the position of the heat source of the mobile phone carried on the mobile phone charging support plate 2. The distance between adjacent obstacle columns 22 is 8 mm.

[0048] The base 1 is provided with a first limiting body 13 for preventing the mobile phone from sliding down.

[0049] A second limiting body 23 for positioning the mobile phone is provided at the upper end of the bearing surface of the mobile phone charging support plate 2; the first limiting body 13 and the second limiting body 23 cooperate to position the mobile phone on the bearing surface.

[0050] The heat dissipation air duct 21 is arranged parallel to the bearing surface; when the base 1 is placed horizontally and the mobile phone charging support plate 2 is in a charging state, the air outlet angle of the outlet of the air duct 4 is the same as the air inlet angle of the heat dissipation air duct 21, and the included angle between the bearing surface and the upper plane of the base 1 is 110° - 150°.

[0051] See Figure 9, when the air flow passes through the obstacle column 22, it will be blocked by the obstacle column 22 and change its direction. In particular, the obstacle columns 22 are distributed in a matrix, which can increase the frequency of wind direction change, thereby reducing the flow velocity of the air flow passing through the area of the obstacle column 22, increasing the residence time of the air in this area, facilitating the air to carry away more heat, and thus achieving the purpose of improving the heat dissipation effect and ensuring the charging efficiency.

[0052] If the obstacle column 22 is not used, see Figure 10 , the air volume at the heat source position is much smaller than that when the obstacle column 22 is used. Therefore, the temperature of the heat will be higher than that when the pressurizing matrix is used.

[0053] Through actual measurement, it can be known that when the obstacle column 22 is used, the highest temperature on the back of the mobile phone is 27.9 °, while when the obstacle column 22 is not used, the highest temperature on the back of the mobile phone is 33.8 °. It can be seen that setting the obstacle column 22 at the heat source position in the heat dissipation air duct 21 can greatly improve the heat dissipation effect.

[0054] The working process of the present invention is as follows:

[0055] According to needs, the mobile phone can be placed on the bearing surface for wireless charging at the same time, and other wireless charging supported products can be placed on the base 1 for wireless charging. When the mobile phone is placed on the bearing surface for wireless charging, the blower 3 works under the control of the control module 6. The blower 3 blows air into the heat dissipation air duct 21. When the air passes through the heat source position of the mobile phone, under the action of the obstacle column 22, the air can stay in the heat dissipation air duct 21 for a longer time, so as to fully absorb the heat and carry it away, and the heat dissipation effect is prominent.

[0059] Other technical features are the same as those in Embodiment 1.

[0060] The working process of this embodiment is as follows:

[0061] When it is necessary to open the mobile phone charging support plate 2, press the driving switch 82, the control module 6 receives the opening control instruction, and drives the driving motor 81 to work. The driving motor 81 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the mobile phone charging support plate 2 to open from the accommodation groove 14.

[0062] When it is necessary to close the mobile phone charging support plate 2, press the driving switch 82, the control module 6 receives the closing control instruction, and drives the driving motor 81 to work.
