Embodiment 1

[0037] Such as Figure 1-2 As shown, the present invention provides a wireless charging device with an automatic positioning function, including: a base, a scanning system disposed in the base, a displacement mechanism for moving the transmitting coil, a light-transmitting plate, and a controller.

[0038] The base 100 is a cavity structure, and the base 100 is provided with a biaxial moving mechanism for moving the transmitting coil, and the transmitting coil is arranged laterally on the moving end of the biaxial moving mechanism, and the position of the transmitting coil is changed by controlling the biaxial moving mechanism , the transmitting coil is connected to the power supply through a driver, and the driver controls the excitation of the transmitting coil to generate an alternating magnetic field, so that the receiving coil receives and generates electric energy for charging the device to be charged, and the driver is provided with a power monitoring unit , to monitor ...

Embodiment 2

[0060] The difference from Embodiment 1 is that, if Figure 2-4 As shown, there are two second single-axis moving mechanisms 620 and 640 with the same structure. It can be understood that a plurality of second single-axis moving mechanisms can be provided as required, and the bottom of each second single-axis moving mechanism A pair of support bases 621 are vertically extended, and a guide block 622 is extended laterally on the inner side wall of the bottom of the support base 621, and the guide block 622 is arranged toward the inside of the support base 621. A second guide groove 612 is correspondingly opened in the length direction, and the guide block 622 is slidably set in the second guide groove 612. On a single-axis moving mechanism 610, the bottom of the second single-axis moving mechanism 620 is separated from the top of the first single-axis moving mechanism 610 by a certain distance, and the moving end 611 of the first single-axis moving mechanism 610 is shuttled and...

Embodiment 3

[0066] The difference from Embodiment 2 is that the transmitting coil includes several groups of concentric coils with different inner diameters, each concentric coil is coaxially arranged, each of the concentric coils is connected to the driver through a controllable switch, and the controllable switch The control terminal is connected to the controller.

[0067] Usually, the specifications of the receiving coils on each device to be charged are not fixed. Several coaxial concentric coils can be set according to the size of several conventional receiving coils. When the transmitting coil and receiving coil are aligned, the same excitation signal Under the premise, each controllable switch is switched one by one, and the receiving coil is excited and charged through different concentric coils. The power monitoring unit monitors the transmission power of each concentric coil in real time, and finally selects the concentric coil with the largest transmission power to excite and c...

Abstract

The invention discloses a wireless charging apparatus with an automatic positioning function. The wireless charging apparatus comprises a base, a transmitting coil, a light-transmitting plate and a controller, wherein a dual-shaft movement mechanism is arranged in the base; a lamp tube is transversely arranged at the first end in the base; a light outlet band opening is axially formed in the surface of the lamp tube; a first light sensitive detection plate is arranged in the upper part space of the base in a transverse movement manner; a second light sensitive detection plate is arranged on the inner side wall of the base on the opposite side of the lamp tube; the transmitting coil is transversely arranged at the moving end of the dual-shaft movement mechanism; the light-transmitting plateis mounted at the upper end of the base in a sealing manner, wherein the first light sensitive detection plate moves along with rotation of the lamp tube; the first light sensitive detection plate orthe second light sensitive detection plate is positioned on a mapping circuit where the light output band opening takes the light-transmitting plate as a reflecting surface, and the signal output ends of the first light sensitive detection plate and the second light sensitive detection plate are jointly connected with an image generation module; and the output end of the image generation module is connected with the controller. By virtue of the wireless charging apparatus, the technical problem of low charging efficiency of the wireless charging apparatus is solved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging device with an automatic positioning function. Background technique [0002] At present, the most common charging solution uses electromagnetic induction. By applying an alternating current of a certain frequency to the primary coil, a certain current is generated in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the reception end, thereby providing The charging device performs wireless charging. [0003] However, there is a defect in the current electromagnetic induction wireless charging method. It is necessary to align the transmitting coil with the receiving coil to achieve an efficient wireless charging process. When the transmitting coil and the receiving coil are slightly deviated, it will cause power transmission efficiency. However, when the user is charging the charging device...
