The charging object of the wireless charging base is not limited here, and the wireless charging base provided by the present disclosure can be applied as long as the electronic device has a rechargeable battery and can realize wireless charging. For convenience of description, the device to be charged is described by taking a mobile phone as an example, and the wireless charging coil is located at a central point of the mobile phone.

Specifically, in the present embodiment, referring to fig. 1, the wireless charging base 10 includes a base 11, a moving mechanism 12, a charging module 13, and a distance sensor 14. The moving mechanism 12 and the charging module 13 are disposed on the base 11, and the moving mechanism 12 drives the charging module 13 to perform two-dimensional motion on the base 11. The distance sensor 14 is disposed above the seat 11 and is configured to collect profile position information of a device to be charged placed on a charging plane of the seat 11.

Above-mentioned wireless charging base 10 passes through distance sensor 14 and gathers the profile position information that waits charging device to be located on pedestal 11, and motion 12 obtains the position of waiting charging device's charging coil according to this profile position information that waits charging device, through motion 12 cooperation motion, can drive the charging coil motion of charging module 13 to the below of waiting charging device's charging coil. Therefore, the charging coil of the charging module 13 can be aligned with the charging coil of the charging device, so that the charging efficiency of the charging device to be treated by the wireless charging base is ensured.

The base 11 is used for carrying a device to be charged. The housing 11 has a cavity 111 for accommodating the charging module 13. The shape of the receiving cavity 111 is substantially the same as the movement area of the charging module 13. The receiving cavity 111 may have a rectangular shape, a circular shape, or the like. Specifically, in the present embodiment, the housing cavity 111 of the housing 11 has a rectangular shape.

The surface of the seat body 11 is a charging plane, and the device to be charged is placed on the charging plane. The shape of the charging plane is not limited, and the charging plane may be circular or square, irregular, or the like. However, the size of the charging plane is smaller than the size of the cross section of the receiving cavity 111. Moreover, for the size of the charging plane, when the device to be charged is placed on the charging plane at will, it is ensured that the charging module 13 of the device to be charged can move through the moving of the charging module 13, so that the transmitting coil of the charging module 13 can move to the lower side of the receiving coil of the device to be charged.

The moving mechanism 12 is disposed in the receiving cavity 111 of the base 11. The moving mechanism 12 includes a first moving component 121 and a second moving component 122, and the second moving component 122 is movably disposed on the first moving component 121. It is understood that the first moving component 121 can be fixedly disposed on the seat 11, and can also be movably disposed relative to the seat 11.

The moving direction of the second moving element 122 on the first moving element 121 intersects with the moving direction of the charging module 13 on the second moving element 122, and the included angle may be an acute angle, a right angle or an obtuse angle. Specifically, the moving direction of the second moving element 122 on the first moving element 121 is perpendicular to the moving direction of the charging module 13 on the second moving element 122. For convenience of explanation, provision is now made: the moving direction of the second moving element 122 on the first moving element 121 is the Y-axis direction. The moving direction of the charging module 13 on the second moving assembly 122 is the X-axis direction. Therefore, the first moving assembly 121, the second moving assembly 122, and the charging module 13 may move to the corresponding positions according to the coordinates of the target position.

Referring to fig. 2, in the present embodiment, the first moving assembly 121 is fixed on the base 11, and the position of the first moving assembly 121 relative to the base 11 is not changed. The first moving assembly 121 includes a first lead screw 1211 and a first stop 1212. The second moving assembly 122 is movably disposed on the first lead screw 1211. The first blocking plate 1212 is disposed on one side of the first lead screw 1211 for blocking the second moving assembly 122. Two ends of the first blocking plate 1212 are fixed on two inner sidewalls of the seat 11.

Specifically, the first kinematic assembly 121 further comprises a first slider 1213. The second moving assembly 122 is connected to the first lead screw 1211 through the first slider. The first lead screw 1211 is disposed through the first slide block. The first shutter 1212 is fixed to an upper surface of the first slider 1213, and the first shutter 1212 is fixed to a lower surface of the first slider 1213. The first blocking plate 1212 is fixedly disposed, the first block 1213 is fixed, and the first block 1213 cannot rotate relative to the first lead screw 1211 but can only move in the axial direction of the first lead screw 1211. The first lead screw 1211 rotates for one circle, the first slide block 1213 moves for one pitch, and the position of the first slide block 1213 on the first lead screw 1211 is adjusted by controlling the number of the positive rotation and the negative rotation of the first lead screw 1211. The first slider moves to drive the second moving element 122 to move, so as to adjust the position of the second moving element 122 on the first lead screw 1211.

The first motion assembly 121 also includes a first motor 1214. The first motor 1214 is drivingly connected to the first lead screw 1211. The first motor 1214 rotates the first lead screw 1211. The position of the chassis on the second screw rod is adjusted by adjusting the rotating speed and the rotating time of the first motor 1214. In other embodiments, the first motor 1214 may be omitted, and the first lead screw 1211 may be driven to rotate by the outside or by a manual operation.

The second moving assembly 122 includes a chassis 1221 for carrying the charging module 13, a second lead screw 1222, and a second stopper 1223. The base plate 1221 is movably disposed on the second lead screw 1222.

The chassis 1221 is used for carrying the charging module 13, and the chassis 1221 moves, and the charging module 13 moves accordingly. Moreover, the charging module 13 is disposed at the center of the chassis 1221, and the center of the chassis 1221 is aligned with the center of the charging module 13, so that when the chassis 1221 moves to the target position, it is ensured that the charging module 13 also moves to the center.

It can be understood that if there is a deviation between the center position of the device to be charged and the center position of the chassis 1221, when the chassis 1221 moves toward the target position, the center position of the chassis 1221 moves to the target position, and then the chassis 1221 needs to move a certain compensation distance again to compensate for the deviation between the center position of the device to be charged and the center position of the chassis 1221, which results in a large error.

The second lead screw 1222 is arranged in the Y-axis direction. The second motion assembly 122 also includes a second motor 1224. The second motor 1224 is disposed at one end of the second lead screw 1222. The second motor 1224 is drivingly connected to the second lead screw 1222. The second motor 1224 rotates the second lead screw 1222. The position of the base plate 1221 on the second lead screw 1222 is adjusted by adjusting the rotation speed and the rotation time period of the second motor 1224. In other embodiments, the second motor 1224 may be omitted, and the second lead screw 1222 may be rotated by external driving, or may be rotated by manual driving.

The second blocking plate 1223 is disposed at one side of the second lead screw 1222 to block the bottom plate 1221, and the second lead screw 1222 rotates to move the bottom plate 1221 along the axial direction of the second lead screw 1222. Specifically, in the present embodiment, the second baffle 1223 is an elongated plate. The second stopper 1223 of the second stopper 1223 is provided at the bottom side of the second lead screw 1222.

It is understood that the second blocking plate 1223 can also be disposed on the left side or the right side of the second lead screw 1222, as long as the second blocking plate 1223 can block the bottom plate 1221 to prevent the bottom plate 1221 from rotating with the second lead screw 1222. And, the second stopper 1223 is located below the base plate 1221, the second stopper 1223 avoiding interference with the axial movement of the base plate 1221 along the second lead screw 1222.

In this embodiment, the second motion assembly 122 further includes a second slider 1225. The second sliding block 1225 is disposed at one side of the base plate 1221, and the base plate 1221 is movably connected to the second lead screw 1222 through the second sliding block 1225. The second lead screw 1222 is arranged in the second slider 1225 in a penetrating manner, the base plate 1221 is fixedly arranged on the upper surface of the second slider 1225, and the second baffle 1223 is fixedly connected with the lower surface of the second slider 1225. When the second screw 1222 rotates, due to the blocking effect of the second blocking plate 1223 on the second slider 1225, the second slider 1225 cannot rotate relative to the second screw 1222, and can only move along the axial direction of the second screw 1222. The second lead screw 1222 rotates once, the second slider 1225 moves by a pitch, and the position of the second slider 1225 on the second lead screw 1222 is adjusted by controlling the number of the forward and reverse rotations of the second lead screw 1222. The second sliding block 1225 moves to move the base plate 1221, so as to adjust the position of the charging module 13 on the base plate 1221 on the second lead screw 1222.

It is understood that, in other embodiments, when the included angle between the moving direction of the second moving element 122 on the first moving element 121 and the moving direction of the charging module 13 on the second moving element 122 is an acute angle or an obtuse angle, the numbers of the rotation cycles of the first lead screw 1211 and the second lead screw 1222 need to satisfy a corresponding proportional relationship or functional relationship according to the trigonometric function relationship of the included angle, and the purpose of adjusting the position of the charging module 13 can also be achieved.

Or, the moving mechanism 12 may also be a telescopic cylinder, a telescopic motor, a conveyor belt or a moving trolley, and the like, and the charging module 13 is disposed on the moving mechanism 12, and the moving mechanism 12 may also achieve the purpose of driving the charging module 13 to move.

The charging module 13 is fixed on the base plate 1221 and moves along the axial direction of the second lead screw 1222 along with the movement of the base plate 1221. In one embodiment, charging module 13 includes a circuit board 131, a charging coil 132, and a shielding layer 133.

The circuit board 131 is used to arrange the respective electronic components of the charging module 13.

The charging coil 132 is provided on the circuit board 131. The charging coil 132 may be a transmitting coil or a receiving coil. Accordingly, the charging coil of the device to be charged may be a receiving coil or a transmitting coil. The center of the charging coil 132 is the center of the charging module 13. A shield 133 is provided on the surface of charging coil 132. The shielding layer 133 can prevent radiation from affecting the charging efficiency of the charging coil 132.

Specifically, in this embodiment, the charging coil 132 is a transmitting coil. The transmitting coil is used for transmitting electromagnetic energy, the device to be charged is provided with a receiving coil, and the charging coil 132 is used for charging the device to be charged.

In another embodiment, the charging coil 132 may also be a receiving coil, and accordingly, the charging coil of the device to be charged is a transmitting coil. The device to be charged can also charge the battery of the wireless charging base. Therefore, the wireless charging base can also store electric energy through the battery, and the wireless charging base can charge the to-be-charged device when power is cut off. Here, the functions of the charging coil 132 of the charging module 13 and the charging coil of the device to be charged are not limited, and charging can be achieved as long as two charging coils have a transmitting coil and a receiving coil.

It can be understood that the charging coil 132 can also move relatively to the circuit board 131, and the purpose of adjusting the position of the charging coil 132 can also be achieved, and finally the purpose of aligning the charging coil 132 of the charging module 13 with the charging coil of the device to be charged is achieved.

The distance sensor 14 is used for collecting the contour position information of the device to be charged on the seat body 11. The plurality of distance sensors 14 are disposed on the periphery of the seat body 11. The distance sensor 14 can sense the distance relationship between the distance sensor 14 and the outer contour of the device to be charged, so that the position information of the device to be charged on the charging plane can be obtained. It is understood that the distance sensor 14 may be an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, or the like.

Specifically, in the present embodiment, the distance sensor 14 is an ultrasonic distance sensor. The ultrasonic distance sensor sends an ultrasonic signal to each side of the device to be charged and receives the ultrasonic signal reflected by the device to be charged. The ultrasonic distance sensor can send out a modulated ultrasonic signal, the signal is reflected back after reaching the front device to be charged and being received by the ultrasonic distance sensor, the time of the ultrasonic signal going back and forth in the air can reflect the distance between the measured object and the ultrasonic module, and the calculation formula is that the distance is (time is 340 m/s)/2. When the transmitted ultrasonic signal is not reflected back, it indicates that there is no device to be charged. Therefore, the contour position of the device to be charged can be judged according to whether the reflected ultrasonic signal exists or not.

For a device to be charged with a small volume, such as a charging earphone or a watch, etc. Falls within the charging coupling range of the charging coil 132 of the wireless charging base for the entire device to be charged. That is, the charging coupling range of the charging coil 132 of the wireless charging base is larger than the volume of the device to be charged. The distance sensor only needs to acquire the position information of the device to be charged. According to the position information, the charging coil of the charging module moves to the position below the charging device to be charged, the charging device to be charged falls into the charging coupling range of the charging coil, and high-efficiency charging of the charging device to be charged can be achieved.

Specifically, in the present embodiment, the device to be charged is described by taking a mobile phone as an example. The contour position information obtained by the distance sensor also includes the contour shape of the device to be charged and the length information of each side of the contour. Because the charging coil of the mobile phone is positioned at the central point of the mobile phone. And calculating the position of the central point of the mobile phone with the outline shape according to the outline position information of the mobile phone, the outline shape of the mobile phone and the length information of each side edge of the outline shape.

Firstly, contour position information of the mobile phone is acquired according to a distance sensor, and the contour position information is only the position of the mobile phone contour on a charging platform. And, whether there is a reflected ultrasonic signal to each side of the mobile phone through the distance sensor, can obtain the shape of the outline of the mobile phone. The outline of the mobile phone is rectangular. On each side, the length of the side is calculated by recording the start to end position of the reflected ultrasonic signal. The position coordinate of the central point of the mobile phone can be calculated by equally dividing the length of each side. And the center of the charging coil of the mobile phone is aligned with the center of the mobile phone, and the calculated position coordinate of the center point of the mobile phone is the center position coordinate of the charging coil.

And, four distance sensors 14 are provided at four apexes of the charging plane, respectively. The distance sensor 14 is installed at a height higher than the charging plane, and the plurality of distance sensors 14 are located on the same height plane. The distance sensor 14 is located at a height such that the device to be charged is within the measurement height range of the distance sensor 14 when the device to be charged is placed on the charging plane.

In other embodiments, the distance sensors 14 may also be 5, 6, etc. A plurality of distance sensor 12 can evenly distributed in the periphery on the plane of charging, and a plurality of distance sensor 12 can be followed a plurality of angles, treats each side of charging device and carries out the induction measurement to guarantee that distance sensor 12 can completely measure the length information of each side of the profile of treating charging device.

Therefore, the ultrasonic distance sensors at the four corners of the charging plane of the seat 11 cooperate with each other to scan the length and position information of each side of the four-side profile of the device to be charged.

The wireless charging dock 10 also includes a plurality of dials 15. The plurality of rotating discs 15 are distributed on the periphery of the seat body 11. The distance sensor 14 is correspondingly arranged on the turntable 15. The turntable 15 is correspondingly arranged according to the placement requirement of the distance sensor 14. Moreover, the turntable 15 can drive the distance sensor 14 to rotate, the distance sensor 14 rotates, the scanning range of the distance sensor 14 can be improved, and the accuracy of the contour position information of the device to be charged, which is acquired by the distance sensor 14, is improved.

It will be appreciated that the turntable 15 may be omitted. For the accuracy of the profile position information of the device to be charged, which is acquired by the distance sensor 14, to be improved, a larger number of distance sensors 14 may be provided. The plurality of distance sensors 14 can completely and completely scan the device to be charged, so that the accuracy of the contour position information of the device to be charged, which is acquired by the distance sensors 14, is ensured.

Referring to fig. 3, the wireless charging base 10 further includes a processor 16. The processor 16 is electrically connected with the distance sensor 14, and the processor 16 is used for moving the charging coil of the charging module 13 to the lower part of the charging coil of the device to be charged according to the contour position information.

In this embodiment, the ultrasonic distance sensors at four corners cooperate with each other to scan the position information of the four sides of the device to be charged. And obtaining the position coordinates of the device to be charged according to the four-side outline position information of the device to be charged. And determining the target position coordinate to which the charging module moves according to the position coordinate of the device to be charged.

It is understood that the processor 16 may be disposed inside the wireless charging dock 10, or may exist independently of the wireless charging dock 10.

The distance sensor 14 may be electrically connected to a built-in processor. The distance sensor 14 sends the acquired contour position information of the device to be charged to the processor 16, and the processor 16 receives the contour position information to obtain the position coordinates of the device to be charged. And determining the target position coordinate to which the charging module 13 moves according to the position coordinate of the device to be charged, and feeding back the target position coordinate to the moving mechanism 12.

In other embodiments, the distance sensor 14 may also be electrically connected to an external processor. The distance sensor 14 collects contour position information, the wireless charging base 10 sends the contour position information to the processor, the processor receives the contour position information, position coordinates of the device to be charged are obtained, target position coordinates to which the charging module 13 moves are determined according to the position coordinates of the device to be charged, and the target position coordinates are fed back to the wireless charging base 10.

The outline of the mobile phone is extracted through the position information of the four-side outline of the mobile phone, a rectangle formed by the four-side outline of the device to be charged is obtained, the coordinate position information of the center point of the rectangle is the coordinate of a charging coil of the mobile phone, and the coordinate of the charging coil of the mobile phone is the target position coordinate.

The processor 16 is also in electrical signal communication with a first motor 1214 and a second motor 1224, respectively. The movement mechanism moves the charging coil of the charging module to the target position coordinate.

The processor 16 controls the first motor 1214 to rotate according to the X-axis coordinate of the target position coordinate, and adjusts the rotation speed and the rotation time to move the second moving assembly 122 along the first lead screw 1211 until the second moving assembly 122 moves to the X-axis coordinate of the target position. The processor 16 controls the second motor 1224 to rotate according to the Y-axis coordinate of the target position coordinate, and adjusts the rotation speed and the rotation time to move the chassis 1221 along the second lead screw 1222 until the charging module 13 moves to the Y-coordinate position of the target position, so as to finally realize that the charging module 13 moves to the target position coordinate, which is the lower side of the device to be charged.

Here, the sequence of the processor 16 controlling the rotation of the first motor 1214 and the rotation of the second motor 1224 is not limited. It is to be appreciated that the processor 16 may control the first motor 1214 to rotate first, and then control the second motor 1224 to rotate; alternatively, the processor 16 may control the second motor 1224 to rotate before controlling the first motor 1214 to rotate; alternatively, the processor 16 may control the rotation of the first motor 1214 and the second motor 1224 simultaneously.

The processor 16 is electrically connected to the charging module 13. After the charging module 13 is sent to the target position coordinates, the processor 16 activates to turn on the charging module 13, so that the charging module 13 starts to wirelessly charge and transmit signals to start wireless charging. Therefore, the charging coil of the charging module is aligned with the charging coil of the device to be charged, and the charging module charges the mobile phone, so that the maximum transmission efficiency is realized.

It is understood that in other embodiments, the wireless charging base 10 may also be controlled by an external switch device to turn on the charging module 13.

The processor 16 further obtains position coordinates of the device to be charged for a plurality of times in a step of determining a target position coordinate to which the charging module 13 moves according to the position coordinates of the device to be charged; and analyzing according to the position coordinates to obtain a target position coordinate.

When first used, the processor 16 moves the target position coordinates and records the position coordinates of the device to be charged. After multiple uses, the processor 16 records the position coordinates of the device to be charged multiple times. The processor 16 obtains the target position coordinates from the plurality of position coordinates analysis. The target position coordinates represent the position points where the user prefers to place the mobile phone. Processor 16 may control motion mechanism 12 to move charging module 13 to a location where the user prefers to place the phone.

The processor 16 may analyze the target location coordinates with a big data algorithm. For example, when the position coordinates of the device to be charged are within a certain spatial range and the number of occurrences reaches a threshold value, the position coordinates of the device to be charged may be taken as the target position coordinates.

Therefore, when the user uses the wireless charging cradle again, the charging module 13 is located at or near a location where the user prefers to place a mobile phone. Therefore, when the mobile phone is placed on the base body 11, the moving mechanism 12 can move the charging module 13 to the target position coordinate as soon as possible in a short time, so that the time period for a user to wait for the charging module 13 to move in place is reduced, and the charging efficiency of the wireless charging base is improved.

In other embodiments, the wireless charging dock further comprises a display screen. The display screen is electrically connected with the charging module 13. The display screen is used for displaying the position and the motion trail of the charging module. The user can be through observing the display screen, according to the position relation of the position of the module of charging that the display screen shows and target position coordinate, correspond the motion of adjusting motion mechanism's first motion subassembly and second motion subassembly, also can make first motion subassembly and second motion subassembly mutually support equally, make the module of charging move to the below of waiting to charge the device. Similarly, when the charging module moves to the position below the device to be charged, a user can start the charging module through the external switch device, so that the charging module charges the device to be charged.

Above-mentioned wireless charging base, position coordinate through confirming the charging coil who treats charging device, the charging coil that removes the module of charging removes under treating charging device's charging coil, can realize transmitting coil and receiving coil most efficient coupling, promote the coupling degree of electromagnetic field, promote electromagnetic energy transmission's efficiency, reduce the power of transmitting terminal and generate heat, promote the receiving efficiency who treats charging device, reduce transmitting coil and receiving coil's temperature rise, improve wireless charging base's stability and treat charging device charging security.

The outline position of the device to be charged is measured according to the outline position information measured by the distance sensor, so that the position of the charging coil of the device to be charged is determined, and the position of the charging coil can be determined efficiently. The problem that the transmitting coil needs to spend a long time to traverse the position of the receiving coil is avoided, and the problem that the transmitting coil generates excessive heat energy to influence the stability of the wireless charging base in the traversing process is avoided. In addition, the transmitting coil can reach the optimal charging position as quickly as possible by quickly positioning the position of the receiving coil, so that the problem that the channel is occupied by repeatedly sending a power request instruction due to the deviation of the device to be charged can be solved, and the phenomenon that the charging fails or cannot be charged due to the occurrence of Foreign Object Detection (FOD) can be avoided.

In addition, the wireless charging base of the embodiment determines the plane position of the charging coil of the device to be charged in a physical wave mode, so that the complex feedback signal can be prevented from being processed by using a software algorithm, and the risk of processing errors by the algorithm is reduced. Moreover, the distance sensor does not need to communicate with the receiving equipment and the transmitting equipment, does not need to occupy a communication channel, and saves communication resources of the wireless charging base.

Therefore, wireless charging of multiple devices and non-positioning can be achieved through the wireless charging base, the wireless charging base can be used at desks, automobiles, restaurants and the like, and electric energy supply of the charging device is greatly facilitated.

The present disclosure also provides a method for controlling a wireless charging base, referring to fig. 4, the method for controlling a wireless charging base includes the following steps:

step S1, collecting contour position information of the device to be charged on the base body of the wireless charging base.

And step S2, moving the charging module to the position below the device to be charged according to the contour position information.

The wireless charging base control method collects the contour position information of the device to be charged on the base body 11. Then, according to the contour position information, the movement mechanism 12 is moved in a matching manner, so that the charging module can be driven to move to the lower part of the device to be charged. Therefore, the charging coil of the charging module can be aligned with the charging coil of the charging device, and the charging efficiency of the charging device to the wireless charging base is guaranteed.

Referring to fig. 5 and 6, in step S2, the step of moving the charging module to the position below the device to be charged according to the contour position information includes:

step S21, obtaining the position coordinate of the device to be charged according to the contour position information, and determining the target position coordinate to which the charging module moves according to the position coordinate of the device to be charged. The contour position information further includes length information of each side of the contour of the device to be charged.

And step S22, controlling the charging module to move to the target position coordinate.

In step S21, the step of determining the target position coordinate to which the charging module moves according to the position coordinate of the device to be charged specifically includes:

step S211, obtaining position coordinates of the device to be charged for multiple times;

and step S212, analyzing according to the position coordinates to obtain a target position coordinate.

It will be particularly appreciated that the target location coordinates may be derived from a plurality of said location coordinates using a big data analysis algorithm. For example, when the position coordinates of the device to be charged are within a certain spatial range and the number of occurrences reaches a threshold value, the position coordinates of the device to be charged may be taken as the target position coordinates.

In step S212, the target position coordinates represent a position point where the user prefers to place the device to be charged. When the user uses the wireless charging base again, the charging module is located at a position where the user prefers to place the device to be charged or is located near the position. Therefore, when the device to be charged is placed on the seat 11, the moving mechanism 12 can move the charging module to the target position coordinate as soon as possible in a short time, so as to reduce the time period for the user to wait for the charging module to move in place, and improve the charging efficiency of the wireless charging base.
