The preferred embodiments of the present invention will be further described in detail with reference to the accompanying drawings.

The present disclosure provides a wireless charging base. The wireless charging base is used for wirelessly charging the device to be charged. The device to be charged can be electronic equipment such as intelligent mobile terminal, portable power source, electric automobile, notebook computer, unmanned aerial vehicle, electronic book, electron cigarette, intelligent wearing equipment, the robot of sweeping the floor, bluetooth speaker, electric toothbrush and chargeable wireless mouse. 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, the weight of the mobile phone is uniformly distributed, and the wireless charging receiving coil is located at the center of the mobile phone.

Specifically, referring to fig. 1 and 2, a wireless charging base 10 includes a base body 11, a magnetic array 12, a charging cradle head 13, and a charging module 14. The magnetic array 12 is used to detect its position coordinates from the magnetism of the charging coil of the device to be charged 20. According to the position coordinate, the charging cradle head 13 drives the charging module 14 to move, so that the charging module 14 moves to the position below the device to be charged 20.

The base 11 is used for carrying the device 20 to be charged. The base body 11 is provided with a charging platform 112 and a bottom frame 113 for placing the device 20 to be charged. The bottom frame 113 includes a plurality of frames, which form a frame structure. An accommodating cavity 111 for accommodating the charging module 14 is formed inside the bottom frame 113. The shape of the receiving cavity 111 is substantially the same as the movement area of the charging module 14. 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. Specifically, in the present embodiment, the accommodating cavity 111 is defined by a plurality of moving rails of the charging cradle head 13.

The device to be charged 20 is placed on the charging platform 112. The shape of the charging platform 112 is not limited, and the charging platform 112 may be circular or square, irregular, and the like. However, the size of the charging platform 112 is at least larger than the size of the cross section of the receiving cavity 111. Moreover, as for the size of the cross section of the accommodating cavity 111, when the device to be charged is arbitrarily placed on the charging platform 112, it is ensured that the charging module 14 of the device to be charged can be located above the accommodating cavity 111, and it is ensured that the charging module 14 of the wireless charging base can move to the charging module 14 of the device to be charged by moving the charging module 14.

Referring to fig. 3 and 4, the magnetic array 12 is disposed below the charging platform 122. The cross-section of the receiving cavity 111 is rectangular. The magnetic array 12 is rectangular. The magnetic array 12 is used to detect position coordinates based on the magnetism of the charging coil of the device to be charged. The magnetic array 12 includes a plurality of magnetic units 121 distributed in an array. The magnetic units 121 are distributed in a rectangular shape. Thus, magnetic array 12 can correspond to lateral and longitudinal coordinates, with different magnetic elements corresponding to different lateral and longitudinal coordinates.

Specifically, in the present embodiment, the magnetic unit 121 includes a magnetic sensor 122 and an excitation coil 123. The magnetic sensor 122 is disposed at the central cavity of the excitation coil 123.

The magnetic sensor 122 is a hall sensor. The Hall sensor is a sensor manufactured according to the Hall effect, and when the bias current is fixed for the Hall sensor, the voltage at two ends of the device is completely dependent on the strength of the measured magnetic field. Thus, magnetic array 12 can be used to detect magnetic substances placed on the array. When the magnetic substance is placed on the magnetic array 12, the hall sensor directly below the magnetic substance senses the change of the magnetic field, and returns a trigger signal to obtain the position coordinate of the magnetic substance. Therefore, the mobile phone is placed on the magnetic array, and the position coordinates of the wireless charging receiving coil of the mobile phone can be located.

The detection radius of the magnetic unit 121 is 25mm or more. When all the magnetic units 121 on the magnetic array 12 are activated to emit excitation, the corresponding hall sensors 122 detect the 50mm diameter solid circle, and the coordinate position covered by the solid circle on the array is obtained. The excitation coil 123 is used to emit energy to magnetize the shield. The shielding layer of the receiving coil of the mobile phone is ferrite or nanogold, and the soft magnet does not have magnetism. The excitation coil 123 transmits energy to the shield of the receiving coil and magnetizes the shield. Therefore, the hall sensor can detect the position coordinates of the receiving coil of the cellular phone having no magnetism.

Because the magnetic substances on the mobile phone are distributed differently, such as sound, vibration motors, camera motors and the like, the distribution positions of the magnetic substances in the mobile phones of various models are different, and the magnetic unit 121 uses the exciting coil 123 to avoid the interference of the magnetic substances, so that the position coordinates of the wireless charging receiving coil can be accurately detected, and the position of the wireless charging receiving coil of the mobile phone can be accurately positioned. Therefore, each magnet unit 121 needs to be provided with an excitation coil 123 for transmitting energy on the magnet array 12.

When all the magnetic units 121 on the magnetic array 12 are activated to emit excitation, the corresponding hall sensors 122 detect the 50mm diameter solid circle, and the coordinate position covered by the solid circle on the array is obtained.

Referring to fig. 2 and 5, the charging cradle head 13 is movably disposed in the base 11. The charging cradle head 13 is disposed in the accommodating cavity 111 of the base 11. The charging cradle head 13 includes a first moving assembly 131 and a second moving assembly 132, and the second moving assembly 132 is movably disposed on the first moving assembly 131. It is understood that the first moving component 131 can be fixedly disposed on the base 11, or can be movably disposed relative to the base 11.

The moving direction of the second moving element 132 on the first moving element 131 intersects with the moving direction of the charging module 14 on the second moving element 132, 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 132 on the first moving element 131 is perpendicular to the moving direction of the charging module 14 on the second moving element 132. For convenience of illustration, the moving direction of the second moving element 132 on the first moving element 131 is defined as the Y-axis direction; the moving direction of the charging module 14 on the second moving element 132 is the X-axis direction. Therefore, the first moving assembly 131, the second moving assembly 132, and the charging module 14 may move to the corresponding positions according to the coordinates of the target position.

Referring to fig. 3, in the present embodiment, the first moving assembly 131 is fixed on the base body 11, and the position of the first moving assembly 131 relative to the base body 11 is not changed. The first moving assembly 131 includes a first lead screw 1311 and a first stopper 1312. The second motion assembly 132 is movably disposed on the first lead screw 1311. The first blocking plate 1312 is disposed at one side of the first lead screw 1311 for blocking the second moving assembly 132. Two ends of the first blocking plate 1312 are fixed on two inner sidewalls of the seat 11.

Specifically, the first motion assembly 131 further includes a first slider 1313. The second moving assembly 132 is connected to the first lead screw 1311 through a first slider. The first lead screw 1311 is inserted into the first slider. The first barrier 1312 is fixed to an upper surface of the first block 1313, and the first barrier 1312 is fixed to a lower surface of the first block 1313. If the first stopper 1312 is fixedly provided, the first block 1313 is fixed, and the first block 1313 cannot rotate relative to the first screw 1311 but can move only in the axial direction of the first screw 1311. The first lead screw 1311 rotates once, the first slide 1313 moves by one pitch, and the position of the first slide 1313 on the first lead screw 1311 is adjusted by controlling the number of cycles of forward rotation and reverse rotation of the first lead screw 1311. The first slide moves to drive the second motion assembly 132 to move, so as to adjust the position of the second motion assembly 132 on the first lead screw 1311.

The charging cradle head 13 further includes a motor 133. Specifically, the first motion assembly 131 further includes a first motor 1314. The first motor 1314 is in driving connection with the first lead screw 1311. The first motor 1314 drives the first lead screw 1311 to rotate. The position of the chassis on the second lead screw is adjusted by adjusting the rotation speed and the rotation time of the first motor 1314. In other embodiments, the first motor 1314 can be omitted, and the first lead screw 1311 can be driven to rotate by the outside or driven to rotate by a human.

The second moving assembly 132 includes a chassis 1321 for carrying the charging module 14, a second lead screw 1322, and a second baffle 1323. The bottom plate 1321 is movably disposed on the second lead screw 1322.

The chassis 1321 is used to carry the charging module 14, and the chassis 1321 moves, with the corresponding movement of the charging module 14. Also, the charging module 14 is disposed at the center of the chassis 1321, and the center of the chassis 1321 is aligned with the center of the charging module 14, so that when the chassis 1321 moves to the target position, it is ensured that the charging module 14 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 1321, when the chassis 1321 moves toward the target position, the center position of the chassis moves to the target position, and then the chassis 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 1321, which causes a large error.

The second lead screw 1322 is disposed in the Y-axis direction. The second motion assembly 132 also includes a second motor 1324. The second motor 1324 is disposed at one end of the second lead screw 1322. The second motor 1324 is drivingly connected to the second lead screw 1322. The second motor 1324 drives the second lead screw 1322 to rotate. The position of the base plate 1321 on the second lead screw 1322 is adjusted by adjusting the rotation speed and the rotation time period of the second motor 1324. In other embodiments, the second motor 1324 may be omitted, and the second lead screw 1322 may be rotated by external driving or by manual driving.

The second baffle 1323 is disposed at one side of the second lead screw 1322 for blocking the bottom plate 1321, and the second lead screw 1322 rotates to move the bottom plate 1321 along the axial direction of the second lead screw 1322. Specifically, in the present embodiment, the second baffle 1323 is a long and narrow plate. A second stopper 1323 of the second stopper 1323 is provided on a bottom side of the second lead screw 1322. It is understood that the second baffle 1323 can be disposed on the left or right side of the second lead screw 1322, as long as the second baffle 1323 can block the bottom plate 1321 to prevent the bottom plate 1321 from rotating with the second lead screw 1322. Also, a second stopper 1323 is located below the bottom plate 1321, and the second stopper 1323 avoids interfering with the axial movement of the bottom plate 1321 along the second lead screw 1322.

In this embodiment in particular, the second motion assembly 132 further comprises a second slide 1325. The second block 1325 is disposed on one side of the bottom plate 1321, and the bottom plate 1321 is movably connected to the second lead screw 1322 through the second block 1325. The second lead screw 1322 penetrates through the second sliding block 1325, the bottom plate 1321 is fixedly arranged on the upper surface of the second sliding block 1325, and the second baffle 1323 is fixedly connected with the lower surface of the second sliding block 1325. When the second lead screw 1322 rotates, due to the blocking effect of the second blocking plate 1323 on the second slide block 1325, the second slide block 1325 cannot rotate relative to the second lead screw 1322, but can only move along the axial direction of the second lead screw 1322. The second lead screw 1322 rotates for a circle, the second slide block 1325 moves for a pitch, and the position of the second slide block 1325 at the second lead screw 1322 is adjusted by controlling the number of the positive rotation and the negative rotation of the second lead screw 1322. The second slide block 1325 moves to drive the bottom plate 1321 to move, so as to adjust the position of the charging module 14 on the bottom plate 1321 on the second lead screw 1322.

It is understood that, in other embodiments, when the included angle between the moving direction of the second moving assembly 132 on the first moving assembly 131 and the moving direction of the charging module 14 on the second moving assembly 132 is an acute angle or an obtuse angle, the number of rotation cycles of the first lead screw 1311 and the second lead screw 1322 needs to satisfy a corresponding proportional relationship or functional relationship according to a trigonometric function relationship of the included angle, and the purpose of adjusting the position of the charging module 14 can also be achieved.

Or, the charging cradle head 13 may also be a telescopic cylinder, a telescopic motor, a conveyor belt or a moving trolley. The charging module 14 is arranged on the charging cradle head 13, and the purpose of driving the charging module 14 to move can be achieved.

Also, each frame of the bottom frame 113 may be provided with a guide groove to provide a guide function for the movement of the first and second moving

assemblies

131 and 132.

The charging module 14 is arranged on the charging cradle head 13. Specifically, the charging module 14 is fixedly disposed on the bottom plate 1321, and moves along the axial direction of the second lead screw 1322 along with the movement of the bottom plate 1321. In one embodiment, the charging module 14 includes a charging circuit 141 and a charging coil 142.

The charging line 141 is used to arrange the respective electronic components of the charging module 14.

The charging coil 142 is disposed on the charging line 141. The charging coil 142 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 transmitting coil transmits electromagnetic energy, the device to be charged is provided with a receiving coil, and the charging coil 142 is used for charging the device to be charged.

In other embodiments, the charging coil 142 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 142 of the charging module 14 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 142 can also move relative to the charging line 141, and the purpose of adjusting the position of the charging coil 142 can also be achieved, and finally the purpose of aligning the charging coil 142 of the charging module 14 with the receiving coil of the mobile phone can be achieved.

Referring to fig. 6, the wireless charging base 10 further includes a controller 16. The controller 16 is electrically connected with the magnetic array 12 and the charging cradle head 13, the magnetic array 12 sends the position coordinates to the controller 16, and the controller 16 calculates the target position coordinates of the center of the solid circle and the receiving coil for wireless charging of the mobile phone through an algorithm. The controller 16 controls the motor 133 of the charging cradle head 13 to move according to the target position coordinates.

The controller 16 can calculate the movement path of the charging cradle head 13 by comparing the initial position of the charging module 14 with the target position coordinate relationship. The controller 16 controls the charging cradle head 13 to move according to the movement path.

It is understood that the controller 16 may be disposed inside the wireless charging dock 10 or may be independent from the wireless charging dock 10. The controller 16 may be a processor, a control chip, or the like.

The controller 16 is also electrically connected to the first motor 1314 and the second motor 1324, respectively. The controller 16 controls the first motor 1314 and the second motor 1324 to move according to the calculated movement path until the charging module 14 moves to the X coordinate and the Y coordinate of the target position, so as to finally realize that the charging module 14 moves to the target position coordinate, which is the position below the device to be charged.

Here, the sequence of the controller 16 controlling the rotation of the first motor 1314 and the rotation of the second motor 1324 is not limited. It is understood that the controller 16 may control the first motor 1314 to rotate first, and then control the second motor 1324 to rotate; alternatively, the controller 16 may control the second motor 1324 to rotate first, and then control the first motor 1314 to rotate; alternatively, the controller 16 may control the rotation of the first motor 1314 and the second motor at the same time.

The controller 16 is electrically connected to the charging module 14. When the charging cradle head 13 finishes the calculated movement path and the charging module 14 is sent to the target position coordinates, the controller 16 starts the charging module 14, so that the charging module 14 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.
