Problems solved by technology

But the defect of this displacement adjustment device is that: the range of movement of the charging coil is small, only limited to the range of the disc-shaped base, and the telescopic rod in the displacement adjustment device cannot exceed the range of the radius of the base, so it cannot be applied to relatively large Wireless charging of portable electronic devices
In addition, due to the hindrance of the protruding post at the center of the base, the above-mentioned charging coil cannot move to the middle position in the housing, so when the receiving coil in the portable electronic device is just placed in the middle position of the housing, the charging coil will not be able to move correctly. Coupled charging is realized by alignment, which seriously affects the practicability of the product

Embodiment 1

[0034] Such as figure 1 and figure 2 As shown, the wireless charging energy transmitting device of this embodiment includes a casing and a transmitting coil 3 placed inside the casing, a coil driving device, a position detection unit 2 and a control circuit. The casing is composed of an upper casing 1 and a The lower casing 6 is formed, and the device to be charged can be placed on the upper surface of the upper casing 1 for charging. The position detection unit 2 is integrated on a circuit board for detecting the position of the receiving coil in the device to be charged. The circuit board has a detection circuit and also includes several small induction coils that can be magnetically coupled with the receiving coil. The position detection unit 2 detects the position of the receiving coil through the small induction coil on it, and its specific structure and circuit can refer to the description in the patent application 201210491153.1, which will not be repeated here. The ...

Embodiment 2

[0043] This embodiment is proposed on the basis of Embodiment 1. The wireless charging energy transmitting device in this embodiment also includes a light emitting device for displaying the moving track of the transmitting coil 3, and its display position moves with the movement of the transmitting coil 3. . In the upper housing 1 at least the charging area 8 is made of a light-transmitting material, and the light of the light emitting device can pass through the housing to the outside, so that when the transmitting coil 3 moves within the range of the charging area 8, the user can The moving track of the transmitting coil 3 is observed outside the housing through the movement of the light spot.

[0044] The light emitting device in this embodiment mainly has two implementation modes, the first implementation mode is as follows Figure 8 As shown, the light-emitting device includes a beam generator 11 and an inclined reflective surface 12. The beam generator 11 can be a low-p...

Abstract

The invention discloses a wireless charing energy launching device which is capable of utilizing the electromagnetic induction principle to charge mobile equipment. The wireless charging energy launching device comprises a shell body, a launching coil, a coil drive device, a position detection unit and a control circuit. The launching coil, the coil drive device, the position detection unit and the control circuit are arranged in the shell body. The position detection unit is used for detecting the position of a receiving coil. The control circuit is used for controlling the coil drive device to enable the launching coil to move to the position where the launching coil can be in electromagnetic coupling with the receiving coil. The coil drive device comprises a horizontal moving mechanism which is provided with an extension part. A rotating mechanism capable of making the launching coil to be in circumferential swing along a radius is arranged on the extension part. The launching coil arranged on the rotating mechanism can move to any position where the lunching coil can be in electromagnetic coupling with the receiving coil in a charging area by aid of superposition of the motion track of the horizontal moving mechanism and the motion track of the rotating mechanism.

Description

technical field [0001] The invention relates to a wireless charging energy transmitting device utilizing the principle of electromagnetic induction, in particular to a transmitting device in which a transmitting coil can adaptively move and couple charging according to the position of a receiving coil in a device to be charged. [0002] Background technique [0003] With the increasing popularity of portable electronic devices, it is necessary to prepare exclusive charging connectors for charging them. It has become a problem to be solved. Users will inadvertently hoard many charging devices with different connectors, resulting in inconvenience in use and waste of resources. In order to solve the above problems, wireless charging technology came into being. Compared with wired charging, the advantages of wireless charging technology are mainly reflected in convenience and versatility. It mainly uses the principle of electromagnetic induction to charge portable electronic dev...
