For example, in a vehicle-mounted environment, when the vehicle accelerates or decelerates, the terminal device 100 may be displaced relative to the vehicle body due to inertia. For terminal device 100 placed on the vehicle-mounted charging device, relative displacement can occur between the charging device and terminal device 100 due to acceleration or deceleration of the vehicle, and then alignment of first charging coil 110 and the second charging coil of the charging device is not accurate enough, so that transmission efficiency of electric energy is affected, and charging efficiency of a battery of terminal device 100 is reduced.

For example, in an on-vehicle environment, when a vehicle accelerates or decelerates, due to an inertia effect, the charging device 200 may be displaced relative to the terminal device 100 placed on the charging device 200, and then the alignment between the second charging coil 210 and the first charging coil 110 of the terminal device 100 is not accurate enough, so that the transmission efficiency of electric energy is affected, and the charging efficiency of the battery of the terminal device 100 is reduced.

Alternatively, the number of the second magnets 220 may be two, and two second magnets 220 may be disposed at the outer periphery or outside of the second charging coil 210.

Here, the number of the first magnets 120 may be three or more, and similarly, the number of the second magnets 220 may be three or more. However, in order to optimize the device layout of the terminal device 100, the number of the first magnets 120 is preferably two, and accordingly, the number of the second magnets 220 on the charging device 200 is also preferably two.

When the number of the first and second magnets 120 and 220 is one and the first magnet 120 is an electromagnet, the second magnet 220 may be either an electromagnet or a permanent magnet.

When the number of the first magnet 120 and the second magnet 220 is one, and the second magnet 220 is an electromagnet, the first magnet 120 may be either an electromagnet or a permanent magnet.

In the case that the first magnet 120 and/or the second magnet 220 are electromagnets, in order to ensure the magnetic force adsorption effect and the control effect, the iron core of the electromagnet may be made of a material with fast demagnetization, such as soft iron, silicon steel, etc.; the shape of the iron core can be generally selected from bar-shaped or hoof-shaped shapes which are easy to magnetize, the iron core is wound with the coil, and the iron core wound with the coil can generate a magnetic field and has adsorption capacity on a magnetic object by electrifying the coil.

wherein, the first charging coil 110 of the terminal device 100 may be disposed at the bottom side of the terminal device 100, so that the first charging coil 110 is attached to the second charging coil 210 of the charging device 200; the first magnet 120 disposed on the terminal device 100 may also be disposed on the bottom side of the terminal device 100 to perform an adsorption alignment with the second magnet 220 disposed on the charging device 200.

Like this, in the process of using battery charging outfit 200 to carry out wireless charging to terminal equipment 100, can adsorb the counterpoint through first magnet 120 and second magnet 220 to make first charging coil 110 and second charging coil 210 reach the purpose of aiming at, thereby promote the transmission efficiency that second charging coil 210 transmitted the electric energy to first charging coil 110, and then promote battery charging outfit 200 to terminal equipment 100's charging efficiency.

As shown in fig. 4, an embodiment of the present invention provides a wireless charging method, which is applied to a first device, where the first device includes an acceleration detector and a first magnet, and the first magnet is an electromagnet, and the method includes:

Step 401, in the process of transmitting electric energy between the first device and an external second device, controlling the first magnet to work at a first power.

In this step, when first magnet worked with first power, the magnetic adsorption power of first magnet to the second magnet of second equipment was less than the magnetic adsorption power of first magnet to the second magnet when first equipment and second equipment adsorbed the counterpoint, like this at the in-process that first equipment and second equipment carry out power transmission, reduces the magnetic adsorption power of first magnet to the second magnet through reducing operating power, can effectively reduce the charging process, and the required power consumption of magnetism absorption is inhaled.

Optionally, the relative distance between the geometric center of the first charging coil of the first device and the first magnet is equal to the relative distance between the geometric center of the second charging coil of the second device and the second magnet, and the position of the first magnet on the first device corresponds to the position of the second magnet on the second device.

And step 402, acquiring an acceleration value detected by the acceleration detector.

In this step, an acceleration value of the first device may be detected by the acceleration detector.

When the first device is a terminal device, an acceleration value of the terminal device can be detected through an acceleration detector arranged on the terminal device; when the first device is a charging device, an acceleration value of the charging device can be detected through an acceleration detector arranged on the charging device; if the terminal equipment is in the vehicle-mounted environment, the acceleration parameter of the current vehicle can be directly obtained, and the acceleration value of the first equipment is determined based on the acceleration parameter of the vehicle.

And 403, if the detected acceleration value is larger than a preset acceleration value, increasing the magnetic attraction force between the first magnet and the second magnet.

in this step, if the detected acceleration value is larger than the preset acceleration value, it indicates that the first device and the second device can generate relative displacement, and in order to avoid that the charging efficiency of the battery of the terminal device is affected due to the relative displacement of the first device and the second device, the magnetic adsorption force of the first magnet on the second magnet can be increased. Moreover, through increasing the magnetic adsorption, the use of the bracket die can be reduced, the cost is reduced, the charging operation of a user can be simplified, and the intellectualization of the charging process is realized.

Wherein, the magnetic attraction force of the first magnet to the second magnet can be increased by increasing the working power of the first magnet; the magnetic attraction force of the second magnet to the first magnet can also be increased by increasing the working power of the second magnet; the working power of the first magnet and the working power of the second magnet can be increased simultaneously, so that the magnetic adsorption force between the first magnet and the second magnet is increased, and the stability of magnetic connection of the first equipment and the second equipment is ensured.

Like this, through the acceleration change condition based on first equipment to when the acceleration value of first equipment surpassed preset acceleration value, through the magnetic attraction power between increase first magnet and the second magnet, thereby avoid first equipment and second equipment relative displacement to appear, and then improve the charge efficiency to terminal equipment's battery.

It should be noted that, the magnitude of the magnetic attraction force between the first magnet and the second magnet can be determined according to the magnitude of the acceleration value, and then the current corresponding to the magnitude is conducted, so that the problem of electric quantity waste caused by the fact that the acceleration change is small and the current is large is avoided. Wherein the absolute value of the acceleration value is in positive correlation with the magnetic adsorption force.

Optionally, if the detected acceleration value returns to a normal level, for example, is smaller than a preset acceleration value, the magnetic attraction force between the first magnet and the second magnet is controlled to return to the normal level, so as to reduce the electric quantity loss required by the magnetic attraction force between the first device and the second device.

in this embodiment, one of the first device and the second device is a terminal device, the other is a charging device, and the first device and the second device successfully handshake, that is, the terminal device and the charging device successfully handshake.

When the terminal device is located in the charging area of the charging device, the magnet change condition detected by the terminal device or the charging device can be used, and when the detected magnetic field change condition meets a certain condition, the handshake success between the terminal device and the charging device can be determined, namely the terminal device is located in the preset area of the charging area. The distance between the terminal device and the charging area of the charging device can also be detected, for example, when the distance is less than a certain value, it can be determined that the handshake between the terminal device and the charging device is successful.

the first device and the second device successfully handshake, and then the terminal device can be determined to be located in a charging area of the charging device, and at this time, the first magnet can be controlled to work with first power, so that the first magnet has magnetic adsorption force, magnetic adsorption is performed on a second magnet arranged on the second device, and based on the principle of magnetic adsorption alignment, the first device and the second device are subjected to adsorption alignment, and a first charging coil on the first device and a second charging coil on the second device achieve the purpose of adsorption alignment, so that the charging efficiency of the charging device on a battery of the terminal device is improved.

Optionally, the second magnet is an electromagnet, and the increasing of the magnetic attraction force between the first magnet and the second magnet includes: transmitting first information to the second device, the first information indicating to increase the operating power of the second magnet.

In this embodiment, the first information may be sent to the second device to instruct the second magnet of the second device to operate with higher power, so as to increase the magnetic attraction force of the second magnet, and further improve the magnetic attraction force between the first magnet and the second magnet.

optionally, the first device is a terminal device, the second device is a charging device, and before controlling the first magnet to operate at the first power, the method further includes: detecting the electric quantity of the terminal equipment; if the electric quantity is lower than the preset electric quantity, setting the power of the first power to be a first preset power value; if the electric quantity is higher than or equal to the preset electric quantity, setting the power of the first power to be a second preset power value; and the first preset power value is smaller than the second preset power value.

In this embodiment, the working power of the first magnet may be determined by determining whether the remaining capacity of the terminal device can satisfy the requirement of performing the one-time strong adsorption alignment on the first magnet. Wherein, when can set for terminal equipment's electric quantity for predetermineeing the electric quantity, terminal equipment's electric quantity just in time can satisfy first magnet and carry out once the strong adsorption counterpoint to realize the alignment of first charging coil and second charging coil, improve terminal equipment's charge efficiency.

When the electric quantity of the terminal equipment is lower than the preset electric quantity, the residual electric quantity of the terminal equipment is not enough to perform strong adsorption contraposition once. In this case, the first magnet may be controlled to operate at a first power with a first predetermined power value, so that the first magnet has a certain magnetic attraction force. In addition, in this case, the charging device may further send first information, where the first information is used to indicate that the second magnet, which is an electromagnet, operates with power whose power is a third preset power value, and the third preset power value is set to be greater than the first preset power value, that is, the second magnet generates a larger magnetic attraction force, so that a strong attraction alignment is performed between the second magnet and the first magnet, and the purpose of aligning the first charging coil and the second charging coil is achieved.

When the electric quantity of the terminal equipment is higher than or equal to the preset electric quantity, the first power is set to be the second preset power value, so that the first magnet works with the first power with the power being the second preset power value, the first magnet and the second magnet are subjected to once strong adsorption alignment, and the aim of aligning the first charging coil and the second charging coil is fulfilled.
