Fig. 2A is a kind of flow chart of wireless charging method shown according to an exemplary embodiment, as shown in Figure 2 A, should
Wireless charging method is in intelligent radio charging equipment, this method to may include following realization step:
In step 201, the first voltage that terminal to be charged is sent is received.
In practical application scene, terminal to be charged is placed the wireless charging base of the intelligent radio charging equipment by user
After on seat, which transmits electric energy with fixed power W1, and correspondingly, which can be with by receiving coil
Sense first voltage.
Determine that the receiving coil for the terminal currently placed is set with intelligent radio charging for the ease of intelligent radio charging equipment
Whether standby transmitting coil deviates, and the first voltage sensed is sent to intelligent radio charging by receiving coil and set by terminal
Standby, correspondingly, which receives the first voltage that terminal is sent by transmitting coil.
In step 202, in the corresponding relationship between voltage and offset distance, the corresponding offset of the first voltage is obtained
Distance.
It can be appreciated that terminal can be felt in the case where the central point of transmitting coil is aligned with the central point of receiving coil
The voltage that should be arrived is maximum, at this point it is possible to think that charge efficiency reaches maximum, in the embodiments of the present disclosure, by the maximum voltage
Referred to as set voltage.But, it is assumed that the central point of the transmitting coil deviates the central point of the receiving coil, and offset distance is D,
So, offset distance D is bigger, and the value for the voltage that terminal can sense is smaller.It can be seen that offset distance D and terminal
There are certain corresponding relationships between the voltage that can be incuded.
In practical application scene, pair that is previously stored in the intelligent radio charging equipment between voltage and offset distance
It should be related to.Further, which can be stored in advance in the intelligent radio charging equipment by user, that is to say, be used
Family can first pass through a large amount of corresponding relationship tested and determined between voltage and offset distance in advance, later, be somebody's turn to do what test obtained
Corresponding relationship is stored into the intelligent radio charging equipment.
In this way, can be somebody's turn to do from pre-stored after the intelligent radio charging equipment receives the first voltage that terminal is sent
The corresponding offset distance of the first voltage is obtained in corresponding relationship.
In step 203, it determines the first voltage and sets the voltage difference between voltage, which refers to the hair
The reception voltage of terminal when ray circle is aligned completely with the receiving coil of the terminal.
Due to the reception of the terminal when setting voltage refers to that the transmitting coil is aligned completely with the receiving coil of the terminal
Therefore voltage in order to judge whether deviate between transmitting coil and receiving coil, by the first voltage of terminal transmission and can be somebody's turn to do
It is compared between setting voltage, that is, the voltage difference between the first voltage and the setting voltage is determined, according to the voltage
Difference judges whether to deviate between transmitting coil and receiving coil.
It in step 204, should based on acquired offset distance control when the voltage difference is greater than predeterminated voltage difference
Transmitting coil and the sliding part are mobile, and to determine coil alignment position, which, which refers to, enables to the emission lines
Enclose the position being aligned to greatest extent with the receiving coil of the terminal.
Wherein, which can be by user's customized setting according to actual needs, can also be by the intelligence nothing
Line charge electric equipment default setting, the embodiment of the present disclosure do not limit this.
When the voltage difference is greater than the predeterminated voltage difference, illustrate that the central point of receiving coil much deviates transmitting
The central point of coil, at this time, it may be necessary to the transmitting coil and sliding part movement be controlled based on acquired offset distance, with determination
The position for enabling to the transmitting coil to be aligned to greatest extent with the receiving coil, in order to the position of subsequent adjustment transmitting coil
It sets.
Certainly, if the voltage difference is less than or equal to the predeterminated voltage difference, it may be considered that in the receiving coil
The heart point alignment and coincidence compared with the central point of the transmitting coil, at this point it is possible to the position of adjustment transmitting coil is not needed, namely
It is in that case, to terminate to determine that coil alignment position and the subsequent position to transmitting coil such as are adjusted at the operation,
Directly charged by transmitting coil to terminal.
In addition, above-mentioned control the transmitting coil and sliding part movement based on acquired offset distance, to determine coil
The specific implementation for being directed at position may include following 2041 to 2042 several realization steps:
2041: controlling the transmitting coil and the sliding part is mobile, so that the transmitting coil is respectively to present position
The mobile offset distance of upper and lower, left and right four direction, and obtain the transmitting coil respectively in upper and lower, left and right four direction
On often according to direction voltage that the terminal is sent after mobile.
Above-mentioned offset distance is deviated between receiving coil and transmitting coil in which direction in order to determine, it can be with hair
On the basis of the original position of ray circle, control transmitting coil is up and down, left and right four direction moves the offset distance respectively,
And the transmitting coil is obtained respectively on the four direction of upper and lower, left and right often according to the direction electricity that the terminal is sent after mobile
Pressure.
For example, Fig. 2 B is please referred to, in the case where keeping the sliding rail part motionless, controls the transmitting coil axially side
To above-mentioned offset distance is moved up and down respectively, position A and position C are arrived separately at, and it is in place to obtain transmitting coil respectively
The voltage that terminal is sent when at A and position C is set, is denoted as tertiary voltage and the 4th voltage respectively here.Later, the transmitting is being kept
In the case that coil is in motionless at the position O before movement, controls the sliding part and distinguish along the direction vertical with the sliding rail part
To the right and it is moved to the left the offset distance, respectively reaches position B and position D, and obtains transmitting coil respectively in position B and position
The voltage that terminal is sent when at D, is denoted as the 5th voltage and the 6th voltage respectively here.
What needs to be explained here is that position B and position D and position O are on the same line.
2042: based on the transmitting coil according to each direction four voltages that the terminal is sent after mobile, determining the coil
It is directed at position.
In practical implementations, there may be a maximum voltages in four voltages sent due to the terminal, alternatively, may be used also
There are two maximum voltages for energy, therefore, different according to the number of the maximum voltage, and the above-mentioned transmitting coil that is based on is according to each side
Four voltages that the terminal is sent after to movement, determine that the realization of the coil alignment position is also different, can specifically include as follows
Two kinds of situations:
The first situation: when in four voltages that the terminal is sent there are when a maximum voltage, by the maximum voltage pair
The position answered is determined as the coil alignment position.
If there is a maximum voltage in four voltages that the terminal is sent, illustrate receiving coil in one direction with
Above-mentioned offset distance is deviated between transmitting coil, therefore, the corresponding position of the maximum voltage can be determined as the coil pair
Level is set.
For example, please refer to Fig. 2 B, if there are a maximum voltage in four voltages that the terminal is sent, and the maximum voltage
For tertiary voltage, then the position of the A point can be determined as the coil alignment position.
Second situation: when the terminal send four voltages in there are when two maximum voltages, control the transmitting coil
It is mobile with the sliding part, so that the transmitting coil is from the position before movement between two maximum voltage corresponding directions
Between the mobile offset distance in direction, and obtain the second voltage that the terminal is sent on position after movement；By two maximums
Voltage position corresponding with the maximum voltage in the second voltage is determined as the coil alignment position.
When the terminal send four voltages in there are when two maximum voltages, illustrate that receiving coil is equal in two directions
Identical offset distance is deviated between the transmitting coil, it is generally the case that the corresponding both direction of two maximum voltages
For adjacent direction.In that case, some upward position of the third side of the both direction is also likely to be coil alignment position,
Wherein, which refers to the both direction at the direction at 45 degree of angles.Therefore, in order to determine optimal coil alignment position
It sets, it is mobile that intelligent radio charging equipment can also control the transmitting coil and the sliding part, so that the transmitting coil is from movement
Preceding position obtains the position after movement to mobile offset distance in intermediate direction between two maximum voltage corresponding directions
Set the second voltage of terminal transmission.
For example, please continue to refer to Fig. 2 B, if two maximum voltages are tertiary voltage and the 5th voltage, intelligent radio charging
Equipment can also control the transmitting coil and the sliding part is mobile, so that the transmitting coil is moved at the E of position.Later, it obtains
Take the transmitting coil at the E of position when terminal send second voltage.
Later, two maximum voltages position corresponding with the maximum voltage in the second voltage is determined as the coil pair
Level is set.For example, if the maximum voltage in two maximum voltages and the second voltage is second voltage, position E is true
It is set to the coil alignment position.
It certainly, can if two maximum voltages are the maximum voltage in two maximum voltages and the second voltage
The corresponding position of any maximum voltage in two maximum voltages is determined as the coil alignment position.For example, if this
Maximum voltage in three voltages, the 5th voltage and second voltage is tertiary voltage and the 5th voltage, then can be by position A or position
B is determined as the coil alignment position.
In step 205, it controls the transmitting coil to be moved on the coil alignment position, and passes through the emission lines after movement
Circle charges to the terminal.
After determining coil alignment position, that is, the transmitting coil can control to be moved to the coil alignment position, it is subsequent to guarantee
Maximum is reached to the charge efficiency of terminal.Wherein, different according to determining coil alignment position, it controls the transmitting coil and is moved to
Specific implementation on the coil alignment position is also different.For example, Fig. 2 B is please referred to, if determining the coil pair by above-mentioned steps
Level is set to position A or position C, then the sliding part can be kept motionless, controls the transmitting coil and is moved to position A or position C
Place.For another example, if determining that the coil alignment position is position B or position D by above-mentioned steps, the transmitting coil is kept to be in
It is motionless at original position O, it controls sliding part movement to the right or is moved to the left above-mentioned offset distance, it is mobile to control the transmitting coil
To position B or position D.
It further, may include: logical to the specific implementation that terminal charges above by the transmitting coil after movement
Transmitting coil after crossing the movement sends charge notification message to the terminal, receives the terminal by the transmitting coil after the movement
Based on the charging instruction that the charge notification message is sent, demand voltage and demand current are carried in the charging instruction, according to the need
Voltage and the demand current are asked, is charged by the transmitting coil after the movement to the terminal.
In practical implementations, it needs to realize charging between terminal and the intelligent radio charging equipment by negotiation.Intelligence
Wireless charging device passes through the transmitting coil after the movement and sends charge notification message to the terminal, to notify terminal to adjust
Simultaneously carry out charging preparation in the position of transmitting coil.After terminal receives the charge notification message, can by receiving coil to this
Intelligent radio charging equipment sends the charging instruction for carrying demand voltage and demand current, which is used to indicate intelligent nothing
Line charge electric equipment can start to charge.Wherein, which refers to the voltage swing of terminal actual demand, which is
Refer to the size of current of terminal actual demand.Later, which leads to according to the demand voltage and the demand current
Transmitting coil after crossing the movement charges to the terminal, and correspondingly, which receives electric energy by the receiving coil of itself.
Wireless charging is carried out to terminal in this way, realizing.
Further, during charging, when intelligent radio charging equipment receives stopping charging by transmitting coil
When instruction, terminate charging operations.In the concrete realization, when terminal detects that the charging current into battery is less than predetermined current
When, it is sent to intelligent radio charging equipment and stops charging instruction.Further, which can be by receiving coil to the intelligence
Wireless charging device sends the stopping charging instruction.
Wherein, which can also be defaulted by the terminal and be set by user's customized setting according to actual needs
It sets, the embodiment of the present disclosure does not limit this.For example, the predetermined current is 50mA.
It that is to say, when terminal detects that the charging current into battery is less than predetermined current, illustrate that battery fills with
Electricity, at this point, terminal can notify the intelligent radio by way of sending to the intelligent radio charging equipment and stopping charging instruction
Charging equipment stops charging.

It is accurately adjusted convenient for the subsequent position to the transmitting coil, in the corresponding relationship between voltage and offset distance, is obtained
Take the corresponding offset distance of the first voltage.It is later, mobile based on acquired offset distance control transmitting coil and sliding part,
To be determined to so that the position that the transmitting coil is aligned to greatest extent with the receiving coil of terminal.It is mobile to control the transmitting coil
It on to identified position, and is charged by the transmitting coil after mobile to the terminal, in this way, controlling transmitting coil and connecing
