Problems solved by technology

Generally, the size of the electronic device is larger than that of the charging device. When the user puts the electronic device on the charging device normally, the lateral offset between the center point of the transmitting coil and the center point of the receiving coil is not large. However, due to the design of the coil, the transmitting There will be a large longitudinal offset between the center point of the coil and the center point of the receiving coil, which affects the charging efficiency

Embodiment 1

[0085] The following is an example of the second scenario, and the electronic device 100 is a single coil, and the charging device 200 is a specific implementation process of the coil alignment when the charging device 200 is a double coil.

[0086] Figure 10 Process provided by the embodiment of the present application Figure one The specific implementation process of the coil alignment under the second scene includes:

[0087] S100, the electronic device 100 establishes communication with the charging device 200.

[0088] Specifically, the charging device 200 transmits the PING pulse energy by the upper coil and the lower coil, and the user holds the electronic device 100 to the charging device 200, and the electronic device 100 is on a single-coil and the charging device 200 between a transmitted coil on the charging device 200. When the distance is less than the preset value, the electronic device 100 can receive the PING pulse energy emitted by the transmitting coil on the e...

example 1

[0107] Example 1: See Figure 12 As shown, it is assumed that S101 acquires the model of the charging device 200 as the model A, the coil identification indicates that the charging device 200 is connected to the electronic device 100 as the upper coil, i.e., the upper coil is the first transmit coil. The S103 is obtained to the placement posture of the electronic device 100 is vertical and the first side is facing up. Assume that the query is that the center of the charging device 200 in the model A is in the center point of the coil to the distance between the preset limit is an ACM. Since the placement posture of the electronic device 100 is vertical and the first side is facing up, the center point of the electronic device 100 to the second side of the second side is the center point to predetermodation of the electronic device 100 on the single coil. The distance of the position side, assuming that the center point of the single coil to the second side of the electronic device ...

example 2

[0108] Example 2: See Figure 13 As shown, it is assumed that S101 acquires the model of the charging device 200 as a model A, and the coil identification indicates that the charging device 200 establishes communication with the electronic device 100 is a lower coil, that is, the lower coil is the first transmit coil. S103 acquires the placement posture of the electronic device 100 to appear and the second side is facing up. Assume that the query is that the distance between the center of the model A is in the center point of the lower coil to the preset limit side of the ACM. Since the placement posture of the electronic device 100 is vertical and the second side edge facing up, the center point of the electronic device 100 onto the first side of the first side is the center point to predetermined limit of the electronic device 100 The distance of the bit side, assuming that the center point of the single coil on the electronic device 100 to the first side of the first side, using...

Abstract

Embodiments of the invention provide a coil alignment method and a charging system. The method comprises the steps that after communication between electronic equipment and charging equipment is established, the electronic equipment acquires coil adjustment information, wherein the coil adjustment information comprises at least one selected from coil offset information and bottom plate rotation information, the coil offset information is offset information of a first transmitting coil relative to a first receiving coil, the first transmitting coil is a transmitting coil which establishes communication with the electronic equipment on the charging equipment, the first receiving coil is a receiving coil which communicates with the first transmitting coil, and the bottom plate rotation information is rotation information of a bottom plate on the charging equipment relative to the electronic equipment; and the electronic equipment sends a control instruction to the charging equipment, and the control instruction carries the coil adjustment information, so the charging equipment adjusts the transmitting coil on the charging equipment according to the control instruction, alignment of the transmitting coil and the receiving coil in a longitudinal direction can be realized, and charging efficiency is improved.

Description

Technical field [0001] The present application embodiment relates to the field of wireless charging, and more particularly to a coil alignment method and a charging system. Background technique [0002] With the development of wireless charging technology, more and more electronic devices have wireless charging functions, allowing the user to charge the electronic device directly on the charging device, and the user needs charging line in traditional charging technology. Compared with the electronic device, the operation when the user is charging is to be charged, and the user experience is improved. [0003] A transmitting coil is provided on the charging device, and the receiving coil is provided on the electronic device. When the center point of the transmitting coil is smaller than a particular value, the receiving coil can receive the magnetic field energy transmitted by the transmitted coil, ie It is possible to realize charging, but the center point of the transmitting coi...
