specific Embodiment approach 3

[0045] Such as image 3 As shown, a schematic exploded perspective view of a wireless charging device according to the third embodiment of the invention. The third embodiment includes: a lower body cover 10, a rotating device 20, a wireless transmitting assembly 30, and an upper body cover 40. The rotating device 20 is installed in the lower body cover 10 and fixedly connected with the wireless transmitting assembly 30. The upper body cover 40 and the lower body cover 10 are assembled by snap-fitting.

[0046] The rotating device 20 includes: a gear 21, a motor 22 and a transmission member 23; the motor 22 drives the gear 21 to rotate through the transmission member 23. Specifically, a connecting member 211 is provided at the shaft center of the gear 21, and the edge of the gear 21 has a plurality of serrations (not shown in the figure), and the serrations and the serrations (not shown in the figure) of the transmission member 23 engage with each other. When the transmission mem...

specific Embodiment approach 4

[0056] For more details in the fourth embodiment, please refer to the first embodiment, and the repetition will not be repeated.

[0057] The fourth embodiment of the present invention detects the charging parameters of the charging coil. When the charging parameter does not match the preset reference, the position of the charging coil is automatically adjusted until the charging parameter matches the preset reference, that is, the charging coil Align with the device to be charged. At this time, the charging equipment has the highest charging efficiency, the least energy consumption, and the shortest charging time.

Abstract

The invention relates to a wireless charging device and method. The wireless charging device comprises a coil drive circuit for driving a charging coil to operate; and an alignment detection circuit for detecting a charging parameter in the coil drive circuit, determining that the charging coil and a to-be-charged device to be aligned when a charging parameter matches a preset reference and keeping charging at the present position.When the charging parameter does not match the preset reference, a rotation control circuit is trigger to begin working. The wireless charging device also comprises a rotation control circuit used for controlling the rotation apparatus to rotate after being triggered by the alignment detection circuit; and a rotation apparatus used to rotate under driving of the rotation control circuit and triggering the coil drive circuit to begin working after the rotation is stopped. According to the embodiment of the present invention, the position of the charging coil is automatically adjusted by detecting the charging parameter of the charging coil, thereby solving the problem of misregistration between the wireless charging device and the to-be-charged device, improving the charging efficiency, reducing energy loss and shortening the charging time .

Description

【Technical Field】 [0001] The present invention relates to the field of charging technology, in particular to a wireless charging device and a method thereof. 【Background technique】 [0002] With the continuous evolution and development of electronic technology, wireless charging devices are now more popular in the market. [0003] However, since the wireless charging technology is charged by induction between coils, the charging device and the device to be charged do not need to be connected by wires. Therefore, as far as existing wireless charging devices are concerned, users are prone to misalignment during use. Inaccurate alignment will greatly reduce the charging efficiency and poor user experience. [0004] Therefore, the slow charging speed has become a relatively large complaint point among current wireless charging products. [Content of the invention] [0005] The technical problem to be solved by the present invention is to provide a wireless charging device and method tha...
