Wireless charging device and electronic equipment

Technical Field

The application relates to the technical field of electronic equipment, in particular to a wireless charging device and electronic equipment.

Background

In recent years, since a wireless charging technology breaks through the limitation that the conventional wired charging technology needs to plug and unplug wires, the technology is gradually emerging in the fields of electronic equipment, electric vehicles and the like. Taking an electronic device as an example, the transmitting end coil is arranged in the wireless charging device, the receiving end coil is arranged in the electronic device to be charged, and energy can be transmitted from the wireless charging device to the electronic device through the magnetic field coupling effect between the transmitting end coil and the receiving end coil. In wireless charging technology, an important technical difficulty is that the distance between the transmitting end coil and the receiving end coil needs to be limited within a certain range to ensure that energy can be efficiently transmitted.

In order to solve the above technical difficulties, one solution of the prior art is to use an automatic alignment technology, that is, an automatic aligner is disposed in the wireless charging device, and the automatic aligner is used to move the transmitting end coil in the wireless charging device, so as to achieve alignment between the transmitting end coil and the receiving end coil. Since the transmitter coil needs to be moved to align with the alignment, the lead wire connected to the circuit board cannot be fixed. Therefore, during the movement of the transmitting end coil, the lead wire is easily pulled or irregularly moved, which affects the normal operation of other electronic devices.

SUMMERY OF THE UTILITY MODEL

The application provides a wireless charging device and electronic equipment to reduce the dragging of coil lead wires in the process of coil movement, and the controllability of the position of the coil lead wires is realized.

In a first aspect, the present application provides a wireless charging device. The wireless charging device may include a housing, and a circuit board, a coil tray, a conductive moving assembly, and a driver disposed at the housing. Specifically, the conductive moving assembly may include a first slider, a second slider, a first conductive rod, and a second conductive rod. The coil may be fixedly connected with a coil tray, and the coil tray may be fixedly connected with the first slider and the second slider. The first slider is movable relative to the first conductive rod, and the first lead end of the coil is electrically connected to the circuit board through the first slider and the first conductive rod. The second slider is movable relative to the second conductive rod, and the second lead end of the coil is electrically connected to the circuit board through the second slider and the second conductive rod.

When the wireless charging device is in a charging working state, the driver can drive the first sliding part to move relative to the first conducting rod and drive the second sliding part to move relative to the second conducting rod, so that the coil tray and the coil move along with the first sliding part and the second sliding part, and alignment of the coil of the wireless charging device and the coil of the equipment to be charged is achieved. In addition, the circuit board, the first conducting rod, the first sliding part, the coil, the second sliding part, the second conducting rod and the circuit board are electrically connected in sequence to form a complete charging loop. Because the coil can move together with the first sliding part and the second sliding part and is electrically connected to the circuit board through the conductive moving assembly, a lead wire for connecting the coil and the circuit board does not need to be set to be too long, so that the lead wire of the coil can be prevented from being pulled, and the crosstalk of the lead wire to a charging circuit after the coil is electrified can be avoided.

In a specific technical solution, the first sliding member may be a first elastic sheet, and the second sliding member may be a second elastic sheet. In this embodiment, the first elastic piece may be clamped to the first conductive rod, and the second elastic piece may be clamped to the second conductive rod, so that the first elastic piece may translate along the first conductive rod and be electrically connected to the first conductive rod, and the second elastic piece may translate along the second conductive rod and be electrically connected to the second conductive rod. When the conductive moving assembly is assembled, only the first elastic sheet is clamped on the first conductive rod and the second elastic sheet is clamped on the second conductive rod, so that the assembling steps of the wireless charging device are simplified.

In another specific technical solution, the first sliding member may include a conductive shell and a third elastic sheet, and the second sliding member may include an elastic member and a thimble. Specifically, the third elastic sheet is abutted against the conductive shell, and the conductive shell is connected to the first conductive rod in a sliding mode.

The other end of the elastic piece can be connected with the thimble and is used for applying a contact force towards the second conducting rod to the thimble. In the scheme, the first lead end is electrically connected to the circuit board sequentially through the third elastic sheet, the conductive shell and the first conductive rod, and the second lead end is electrically connected to the circuit board sequentially through the thimble and the second conductive rod. When the wireless charging device is in a charging working state, the conductive shell translates along the first conductive rod and is electrically connected with the first conductive rod, and the thimble keeps being abutted against and electrically connected with the second conductive rod under the action of the elastic piece, so that the first lead end and the second lead end of the coil can be respectively kept in good electrical connection with the circuit board.

The first conductor bar may be parallel to the second conductor bar. In this embodiment, the coil tray can be moved in one direction or in two directions.

Specifically, the first conductive rod may be a screw rod, and the first sliding member is in transmission connection with the screw rod. The second sliding part is connected with the second conducting rod in a sliding mode. When the driver drives the first sliding part to move horizontally along the screw rod, the screw rod is parallel to the second conducting rod, and the first sliding part can drive the coil tray and the second sliding part to move along the extension direction of the screw rod, so that unidirectional movement of the coil is realized. In addition, the area of a charging loop formed by the parallel lead screw, the second conducting rod, the coil and the circuit board is smaller, so that the electromagnetic interference of the charging loop on the coil is reduced, and the electromagnetic compatibility of the charging loop is improved.

In addition, the conductive moving assembly may further include a first lead screw mechanism. Specifically, the first lead screw mechanism may include a first lead screw and a first slider. The first lead screw is parallel to the first conducting rod. The first sliding block is in transmission connection with the first screw rod.

The first lead screw mechanism may further include a first link parallel to the first lead screw. The first slider may be slidably coupled to the first link. When the driver drives the first sliding block to translate along the first screw rod, the first sliding block can also translate along the first connecting rod, so that the first sliding block can be prevented from deflecting around the first screw rod, and the coil tray can be moved more stably.

The first sliding block can be fixedly connected with the coil tray, so that the coil tray only translates along the extension direction of the first screw rod, and unidirectional movement of the coil is ensured.

Further, the conductive moving assembly may include a guide bar perpendicular to the first conductive bar. The first slider and the second slider may be slidably connected to the guide bar. In the scheme, the coil tray can translate along the extension direction of the first screw rod along with the first sliding piece and the second sliding piece and can also translate along the extension direction of the guide rod, so that the coil tray can move along two directions, and the coil can move to any position.

The conductive moving assembly may further include a second screw mechanism. Specifically, the second screw mechanism comprises a second screw and a second sliding block. The second lead screw is perpendicular to the first conducting rod. The second sliding block is in transmission connection with the second lead screw and is fixedly connected with the first conducting rod and the second conducting rod. The first sliding block is fixedly connected with the guide rod. When the coil alignment is needed, the driver can drive the first sliding block to translate along the first screw rod, so that the first sliding block drives the guide rod, the coil tray, the coil, the first sliding piece and the second sliding piece to move along the first screw rod; the driver can also drive the second sliding block to translate along the second screw rod so as to drive the coil tray, the coil, the first sliding part and the second sliding part to move along the extending direction of the guide rod, and therefore the coil can be stably moved to any position.

In addition, the conductive moving assembly may further include a second link. The second connecting rod is parallel to the second screw rod, and the second sliding block can be connected to the second connecting rod in a sliding mode. When the wireless charging device is in a charging working state, the circuit board, the second lead screw, the first conducting rod, the first sliding part, the coil, the second sliding part, the second conducting rod, the second connecting rod and the circuit board are electrically connected in sequence to form a complete charging loop. When the driver drives the second slider to translate along the second lead screw, the second slider can also translate along the second connecting rod, so that the second slider can be prevented from deflecting around the second lead screw, and the coil tray can be moved more stably. In addition, the area of the charging loop is small, so that the electromagnetic interference of the charging loop on the coil is reduced, and the electromagnetic compatibility of the charging loop is improved.

In other embodiments, the first conductive bar may be perpendicular to the second conductive bar. In the scheme, the first sliding part can drive the coil tray and the coil to move along the first conducting rod, and the second sliding part can drive the coil tray and the coil to move along the second conducting rod, so that the coil can move along two directions.

Specifically, the conductive moving assembly may include a third screw mechanism and a fourth screw mechanism. The third screw rod mechanism comprises a third screw rod and a third sliding block. The third lead screw is perpendicular to the first conducting rod. The third sliding block is in transmission connection with the third screw rod and is fixedly connected with the first conducting rod. When the driver drives the third sliding block to translate along the third screw rod, the third sliding block can drive the coil tray and the coil to move along the third screw rod. The fourth screw rod mechanism comprises a fourth screw rod and a fourth sliding block. The fourth lead screw is perpendicular to the second conducting rod. The fourth sliding block is in transmission connection with the fourth screw rod and is fixedly connected with the second conducting rod. When the driver drives the fourth sliding block to translate along the fourth screw rod, the coil tray and the coil can be driven to move along the fourth screw rod. The third screw rod mechanism drives the coil and the coil tray to move along the extending direction of the third screw rod, the fourth screw rod mechanism drives the coil and the coil tray to move along the extending direction of the fourth screw rod, and therefore the two screw rod mechanisms are adopted to respectively drive the coil and the coil tray to move, the coil and the coil tray are enabled to move more stably, and the coil tray can be controlled to move to any position more accurately.

The conductive moving assembly further comprises a third connecting rod and a fourth connecting rod. The third connecting rod is parallel to the third screw rod, and the third sliding block is connected to the third connecting rod in a sliding mode. When the driver drives the third slider to translate along the third screw rod, the third slider can also translate along the third connecting rod, so that the third slider can be prevented from deflecting around the third screw rod, and the coil tray can move more stably. The fourth connecting rod is parallel to the fourth screw rod, and the fourth sliding block is connected to the fourth connecting rod in a sliding mode. When the driver drives the fourth slider to move along the fourth screw rod, the fourth slider can also translate along the fourth connecting rod, so that the fourth slider can be prevented from deflecting around the fourth screw rod. In addition, the circuit board, the third connecting rod, the first conducting rod, the coil, the second conducting rod, the fourth connecting rod and the circuit board are electrically connected in sequence to form a complete charging loop.

The first sliding block, the second sliding block, the third sliding block and the fourth sliding block can be conductive tee pieces, so that the conductive moving assembly can be assembled and disassembled conveniently.

In order to reduce the on-resistance in the charging loop, the surfaces of the first conducting rod and the second conducting rod can be coated with a conductive lubricating layer, so that the heating and energy consumption of the charging loop can be reduced, and the wireless charging efficiency is improved.

The number of coils and conductive moving components may be selected according to the specific requirements of wireless charging, such as charging rate, charging power, etc. For example, the wireless charging device may include a plurality of coils and a plurality of conductive moving elements, where the number of the conductive moving elements is equal to that of the coils, and the conductive moving elements are connected in a one-to-one correspondence. Alternatively, the wireless charging device may comprise a plurality of coils and one conductive moving component, wherein the plurality of coils may be arranged in a specific design, for example in a triangular or rectangular arrangement.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

In wireless charging technology, automatic alignment technology is generally adopted to ensure the distance between the transmitting end coil and the receiving end coil to provide effective energy transfer.

For example, a charging device is used to wirelessly charge a device to be charged. The charging equipment comprises a shell, a transmitting end coil, a circuit board and an automatic aligner, wherein the transmitting end coil, the circuit board and the automatic aligner are arranged in the shell, the automatic aligner is used for driving the transmitting end coil to move in the shell, and the transmitting end coil can be aligned with a receiving end coil of the charging equipment to be charged. Or, the automatic alignment device may also be disposed in the device to be charged to drive the receiving end coil to move in the device to be charged, so as to achieve alignment between the receiving end coil and the transmitting end coil.

However, since the lead wires of the coil are connected to the circuit board, it is generally necessary to set the lead wires of the coil to a long length in order to ensure that the coil is electrically connected to the circuit board during movement. However, the overlong lead is pulled in the moving process of the coil, so that the electric connection between the coil and the circuit board is poor, and the charging efficiency is reduced. In addition, the leads may also move irregularly within the housing, causing crosstalk with other electronic devices.

Therefore, the application provides a wireless charging device and electronic equipment, so that the pulling of the coil lead is reduced in the coil moving process, and the controllability of the position of the coil lead is realized.

Fig. 1 is a schematic structural diagram of a wireless charging device according to an embodiment of the present disclosure. As shown in fig. 1, the wireless charging device 01 includes a housing 11, a coil 12, a coil tray 13, a conductive moving member 14, a circuit board 15, and a driver 16. In the present embodiment, the coil 12 is fixedly connected to the coil tray 13, and the coil tray 13 is used for carrying the coil 12. The coil tray 13 is connected with the conductive moving assembly 14, and the driver 16 can drive the conductive moving assembly 14 to drive the coil tray 13 and the coil 12 to move, so that the coil 12 of the wireless charging device 01 can be aligned with the coil of the device to be charged. In addition, the lead end of the coil 12 can be electrically connected to the circuit board 15 through the conductive moving component 14, and therefore, the connection between the coil 12 and the circuit board 15 does not require that the lead of the coil 12 be too long, so that the lead of the coil 12 can be prevented from being pulled, and crosstalk of the energized lead to a charging circuit in the wireless charging device 01 can be prevented.

The housing 11 may be a frame-type housing in which the coil 12, the coil tray 13, the conductive moving assembly 14, the circuit board 15, and the driver 16 may be disposed; alternatively, the housing 11 may be a support plate, and the coil 12, the coil tray 13, the conductive moving assembly 14, the circuit board 15, and the driver 16 may be disposed at one side of the support plate.

The second lead end is fixedly connected to the second sliding member 142, and the second lead end, the second sliding member 142, the second conductive rod 144 and the circuit board 15 are electrically connected in sequence. Therefore, when the wireless charging device 01 is in the charging operation state, the circuit board 15, the first conductive rod 143, the first slider 141, the coil 12, the second slider 142, and the second conductive rod 144 are electrically connected in sequence, thereby forming a complete charging loop. In this embodiment, the circuit board 15 may include a power circuit having a first connection terminal that may be electrically connected with the first conductive bar 143 and a second connection terminal that may be electrically connected with the second conductive bar 144.

In the embodiments of the present application, "sequentially electrically connected" means that electrical connection is performed in order. For example, the phrase "the first lead terminal, the first slider 141, the first conductive bar 143, and the circuit board 15 are electrically connected in this order" means that the first lead terminal, the first slider 141, the first conductive bar 143, and the circuit board 15 are electrically connected in this order. That is, the first lead terminal is electrically connected to the first slider 141, the first slider 141 is also electrically connected to the first conductive bar 143, and the first conductive bar 143 is also electrically connected to the circuit board 15. Alternatively, the first slider 141 is electrically connected between the first lead terminal and the first conductive bar 143, and the first conductive bar 143 is electrically connected between the first slider 141 and the circuit board 15. For another example, the phrase "the second lead terminal, the second slider 142, the second conductive rod 144, and the circuit board 15 are electrically connected in this order" means that the second lead terminal, the second slider 142, the second conductive rod 144, and the circuit board 15 are electrically connected in this order. That is, the second lead terminal is electrically connected to the second slider 142, the second slider 142 is also electrically connected to the second conductive bar 144, and the second conductive bar 144 is also electrically connected to the circuit board 15. Alternatively, the second slider 142 is electrically connected between the second lead terminal and the second conductive rod 144, and the second conductive rod 144 is electrically connected between the second slider 142 and the circuit board 15. The following description is omitted.

The coil tray 13 is fixedly connected to the first slider 141 and the second slider 142. In order to reduce the impedance influence on the charging circuit, the coil tray 13 may be an insulating tray to prevent the electrical connection between the first lead terminal and the first sliding member 141 and the electrical connection between the second lead terminal and the second sliding member 142 from affecting each other, thereby preventing a short circuit problem.

Alternatively, the second elastic piece 1421 may also be an elastic piece provided with a mounting hole, and the elastic piece is sleeved on the second conductive rod 144. When the second conductive rod 144 is a screw rod, an internal thread may be further disposed in the mounting hole of the second elastic piece 1421, and the internal thread is in threaded fit with the surface of the screw rod, so that the threaded fit between the second elastic piece 1421 and the screw rod is more stable.

The first through hole 131 is provided with a first mounting groove 1311, and the first elastic piece 1411 may be embedded in the first mounting groove 1311. The second through hole 132 is provided with a second mounting groove 1321, and the second elastic piece 1421 may be embedded in the second mounting groove 1321. The first conductive rod 143 may be a lead screw, and the inner wall of the first through hole 131 may be provided with an internal thread 133 to be engaged with the thread of the surface of the lead screw.

Fig. 8 is a schematic structural diagram of the first sliding member and the second sliding member in the embodiment of the present application. As shown in fig. 8, the first sliding member 141 may include a conductive housing 1413 and a third elastic sheet 1414, and the second sliding member 142 may include an elastic member 1423 and a thimble 1424. Specifically, the third elastic sheet 1414 abuts against the conductive housing 1413 and is electrically connected to the conductive housing 1413. One end of the elastic member 1423 is connected to the first sliding member 141 in an insulating manner, that is, the elastic member 1423 may be connected to the conductive housing 1413 in an insulating manner, or the elastic member 1423 may also be connected to the third elastic sheet 1414 in an insulating manner. The other end of the elastic member 1423 is connected to the thimble 1424, and is used for applying an abutting force to the thimble 1424 toward the second conductive rod 144, so that the thimble 1424 can abut against and be electrically connected to the second conductive rod 144. The elastic member 1423 and the thimble 1424 may be fixedly connected, for example, by welding or bonding, or the elastic member 1423 and the thimble 1424 may be connected in contact with each other.

The end of the thimble 1424 contacting the second conductive rod 144 may be a carbon brush structure, so as to achieve a good electrical connection between the thimble 1424 and the second conductive rod 144. Moreover, when the thimble 1424 slides relative to the second conductive rod 144, the carbon brush structure can reduce the friction between the thimble 1424 and the second conductive rod 144, so that the second sliding member 142 moves more smoothly.

In addition, since the first slider 141 and the second slider 142 are conductive structures, in order to avoid electric leakage or accidental touch of the first slider 141 and the second slider 142, the conductive moving assembly 14 may further include an insulating protective shell. For example, in a specific embodiment, the first slider 141 and the second slider 142 are disposed in an insulating protective casing, which is provided with two through holes for the first conductive rod 143 and the second conductive rod 144 to pass through, respectively. Alternatively, the coil tray 13 may be an insulating protective case, and the first slider 141 and the second slider 142 may be provided in the coil tray 13.

With reference to fig. 2, the driver 16 can drive the first sliding member 141 to move relative to the first conductive rod 143, and drive the second sliding member 142 to move relative to the second conductive rod 144, so as to drive the coil tray 13 and the coil 12 to move together. It should be noted that, in the embodiment of the present application, the coil tray 13 may be moved in one direction (referred to as x direction in the present application) in its moving plane, or may be moved in two directions (for example, x direction in the present application, and y direction perpendicular to the x direction), so that the coil tray 13 may be located at any position in the plane.

As shown in fig. 2, the first conductive bar 143 may be parallel to the second conductive bar 144, the first slider 141 may be slidably connected to the first conductive bar 143, and the second slider 142 may be slidably connected to the second conductive bar 144. In this embodiment, the x direction is an extending direction of the first conductor bar 143 and the second conductor bar 144. When the first and second sliders 141 and 142 move in the x direction, the coil tray 13 and the coil 12 also move in the x direction, thereby achieving movement of the coil 12 and the coil tray 13 in one direction.

In this embodiment, the driver 16 may drive the first slide 141 to translate along the first conductive rod 143, and simultaneously drive the second slide 142 to translate along the second conductive rod 144. Alternatively, since the first slider 141 and the second slider 142 are respectively fixedly connected to the coil tray 13, when any one of the first slider 141 and the second slider 142 moves, the coil tray 13 and the other slider can be driven to move. Therefore, the driver 16 may drive only one of the first slider 141 and the second slider 142 without driving both the sliders synchronously, so that it is possible to prevent the first slider 141 and the second slider 142 from moving asynchronously due to asynchronous driving. The unsynchronized movement of the first and second sliders 141 and 142 may cause the coil tray 13 to move unevenly or to be stuck. Therefore, the present embodiment can improve the stability of the movement of the coil tray 13.

For convenience of description, the following description will be made in detail by taking an example in which the driver 16 drives the first slider 141 to translate along the first conductive rod 143.

As shown in fig. 2, in an embodiment of the present application, the first conductive rod 143 may be a lead screw, the first sliding member 141 may be a first elastic sheet 1411, and the second sliding member 142 is a second elastic sheet 1421. The driver 16 is in transmission connection with the screw rod, and when the driver 16 drives the screw rod to pivot, the first elastic sheet 1411 can be driven to move along the x direction, and the coil tray 13 moves along the x direction along with the first elastic sheet 1411. In the process, the second resilient tab 1421 translates along the second conductive rod 144 with the coil tray 13. In this way, the driver 16 only needs to be arranged to drive the lead screw to pivot, thereby simplifying the structure of the wireless charging device 01 and making the movement of the coil tray 13 more stable. When the wireless charging device 01 is in a charging operation state, the circuit board 15, the lead screw, the first elastic sheet 1411, the coil 12, the second elastic sheet 1421, the second conductive rod 144 and the circuit board 15 are electrically connected in sequence, and a complete charging loop is formed. In terms of electromagnetic compatibility, since the area of the charging loop is small, the electromagnetic interference to the coil 12 is also small, and therefore, the structural design in this embodiment can improve the electromagnetic compatibility of the charging loop.

Fig. 9 is a schematic structural diagram of another wireless charging device in the embodiment of the present application. As shown in fig. 9, the electro-conductive assembly may further include a first lead screw mechanism. Specifically, the first lead screw mechanism includes a first lead screw 211 and a first slider 212. The first lead screw 211 is parallel to the first and second conductive bars 143 and 144, and the first lead screw 211 is pivotable with respect to the housing 11. The first slider 212 is in transmission connection with the first lead screw 211. The first slider 212 has a threaded hole and is sleeved on the first lead screw 211, so that the internal thread of the first slider 212 is matched with the thread on the surface of the first lead screw 211. When the coil 12 is aligned, the driver 16 may drive the first slider 212 to move along the first lead screw 211, so that the first slider 212 drives the coil tray 13, the coil 12, the first slider 141, and the second slider 142 to move together along the x direction. In addition, the first lead screw 211 can also carry the coil tray 13 together with the first conductive rod 143 and the second conductive rod 144, so that the movement of the coil tray 13 is more smooth.

It should be noted that, in the above embodiment, the driver 16 drives the first slider 212 may mean that the driver 16 is directly connected to the first slider 212 in a transmission manner. For example, the first slider 212 is coupled to the first lead screw 211 through a screw thread, and when the driver 16 drives the first slider 212 to move along the first lead screw 211, the first slider 212 drives the first lead screw 211 to pivot. Alternatively, the driver 16 driving the first sliding block 212 may also mean that the driver 16 is directly connected with the first lead screw 211 in a transmission manner. For example, the first slider 212 is coupled to the first lead screw 211 in a threaded manner, and when the driver 16 drives the first lead screw 211 to pivot around its central axis, the first lead screw 211 drives the first slider 212 to translate along the x direction.

The first screw mechanism may further include a first link 213. The first link 213 is parallel to the first lead screw 211, and the first slider 212 can be slidably connected to the first link 213. When the driver 16 drives the first lead screw 211 to pivot, the first slider 212 can be driven to move along the x direction, so that the first slider 212 can simultaneously translate along the first lead screw 211 and the first link 213. The first link 213 serves as a guide to guide the first slider 212 to translate along the x direction, so that the first slider 212 can be prevented from deflecting around the first lead screw 211, and the movement of the coil tray 13 is more stable.

The first slider 212 may be fixedly connected to the coil tray 13, so that the coil tray 13 can only move in the x direction, thereby ensuring unidirectional movement of the coil 12.

Alternatively, the first slider 212 may slide with respect to the coil tray 13. For example, fig. 10 is a schematic structural diagram of another wireless charging device in the embodiment of the present application. As shown in fig. 10, the conductive moving assembly 14 may further include a guide bar 145 perpendicular to the first conductive bar 143, and the extending direction of the guide bar is a y direction. The first slider 141 and the second slider 142 may be slidably connected to a guide bar, and the guide bar is fixedly connected to the first slider 212. In this scheme, when the driver 16 drives the first slider 141 and the second slider 142 to move along the x direction, the first slider 141 and the second slider 142 may drive the coil tray 13 and the coil 12 to also translate along the x direction; when the driver 16 drives the first slider 141 and the second slider 142 to move along the guide bar direction, i.e. along the y direction, the first slider 141 and the second slider 142 can drive the coil tray 13 and the coil 12 to translate along the y direction, so that the coil tray 13 and the coil 12 can move along the x direction and the y direction, and the coil 12 can move to any position.

With continued reference to fig. 10, the conductive moving element 14 may further include a second lead screw mechanism. Specifically, the second lead screw mechanism includes a second lead screw 221 and a second slider 222. The second lead screw 221 is perpendicular to the first conductive rod 143, and the second lead screw 221 is pivotable with respect to the housing 11. The second slider 222 is in transmission connection with the second lead screw 221, and the first conductive rod 143 and the second conductive rod 144 are respectively fixedly connected with the second slider 222. The second slider 222 has a threaded hole and is sleeved on the second screw rod 221, so that the internal thread of the second slider 222 is matched with the thread on the surface of the second screw rod 221. When the coil 12 is aligned, the driver 16 may drive the second slider 222 to move along the second lead screw 221, so that the second slider 222 drives the coil tray 13, the coil 12, the first slider 141, and the second slider 142 to move together along the y direction. In addition, the first screw mechanism drives the coil 12 and the coil tray 13 to move along the x direction, and the second screw mechanism drives the coil 12 and the coil tray 13 to move along the y direction, so that the two screw mechanisms are adopted to respectively drive the coil 12 and the coil tray 13 to move, the movement of the coil 12 and the coil tray 13 is more stable, and the coil 12 and the coil tray 13 can be more accurately controlled to move to any position.

It should be noted that, in the above embodiment, the driver 16 drives the second slider 222 may mean that the driver 16 is directly in transmission connection with the second slider 222. For example, the second slider 222 is coupled to the second lead screw 221 through a screw, and when the driver 16 drives the second slider 222 to move along the second lead screw 221, the second slider 222 drives the second lead screw 221 to pivot. Alternatively, the driver 16 driving the second slider 222 may also mean that the driver 16 is directly connected to the second lead screw 221 in a transmission manner. For example, the second slider 222 is coupled to the second lead screw 221 through a screw, and when the driver 16 drives the second lead screw 221 to pivot around its central axis, the second lead screw 221 drives the second slider 222 to translate along the y direction.

In addition, the conductive moving assembly 14 may further include a second link 223. The second link 223 is parallel to the second lead screw 221, and the second slider 222 can be slidably connected to the second link 223. When the actuator 16 drives the second lead screw 221 to pivot, the second slider 222 can be driven to move along the y direction, so that the second slider 222 can simultaneously translate along the second lead screw 221 and the second connecting rod 223. The second link 223 plays a guiding role to guide the second slider 222 to translate along the y direction, so that the second slider 222 can be prevented from deflecting around the second lead screw 221, and the movement of the coil tray 13 is more stable. When the wireless charging device 01 is in a charging working state, the circuit board 15, the second lead screw 221, the first conductive rod 143, the first slider 141, the coil 12, the second slider 142, the second conductive rod 144, the second link 223 and the circuit board 15 are electrically connected in sequence to form a complete charging loop. In addition, the area of the charging loop is small, so that the electromagnetic interference of the charging loop on the coil 12 is reduced, and the electromagnetic compatibility of the charging loop is improved.

Fig. 11 is a schematic structural diagram of another wireless charging device in an embodiment of the present application. As shown in fig. 11, the first conductor bar 143 may be perpendicular to the second conductor bar 144. In this scheme, the first slider 141 can drive the coil tray 13 and the coil 12 to move along the first conductive rod 143, i.e., move along the x direction; the second slider 142 can move the coil tray 13 and the coil 12 along the second conductive rod 144, i.e. along the y direction, so that the coil 12 and the coil tray 13 can move along the x direction and the y direction, and the coil 12 and the coil tray 13 can move to any position in the housing 11.

With continued reference to fig. 11, in one embodiment, the conductive moving assembly 14 may include a third screw mechanism. Specifically, the third screw mechanism includes a third screw 231 and a third slider 232. The third lead screw 231 is perpendicular to the first conductive rod 143, and the third lead screw 231 is pivotable with respect to the housing 11. The third slider 232 is in transmission connection with the third lead screw 231, and the first conductive rod 143 is fixedly connected with the third slider 232. The third slider 232 has a threaded hole and is sleeved on the third lead screw 231, so that the internal thread of the third slider 232 is matched with the thread on the surface of the third lead screw 231. When the coil 12 is aligned, the driver 16 may drive the third slider 232 to move along the third lead screw 231, so that the third slider 232 drives the coil tray 13, the coil 12, the first slider 141, the second slider 142, and the first conductive rod 143 to move together along the x direction.

It should be noted that, the driver 16 drives the third slider 232 may mean that the driver 16 is directly connected to the third slider 232 in a transmission manner. For example, the third slider 232 is threadedly coupled to the third lead screw 231, and when the driver 16 drives the third slider 232 to move along the third lead screw 231, the third slider 232 drives the third lead screw 231 to pivot. Alternatively, the driver 16 driving the third sliding block 232 may also mean that the driver 16 is directly connected to the third lead screw 231 in a transmission manner. For example, the third slider 232 is coupled to the third lead screw 231 by a screw, and when the driver 16 drives the third lead screw 231 to pivot around its central axis, the third lead screw 231 drives the third slider 232 to translate along the y direction.

The conductive moving assembly 14 may further include a fourth screw mechanism. Specifically, the fourth screw mechanism includes a fourth screw 241 and a fourth slider 242. The fourth lead screw 241 is perpendicular to the second conductive rod 144, and the fourth lead screw 241 is pivotable with respect to the housing 11. The fourth slider 242 is in transmission connection with the fourth screw 241, and the second conductive rod 144 is fixedly connected with the fourth slider 242. The fourth slider 242 has a threaded hole and is sleeved on the fourth screw rod 241, so that the internal thread of the fourth slider 242 is matched with the thread on the surface of the fourth screw rod 241. When the coil 12 is aligned, the driver 16 may drive the fourth slider 242 to move along the fourth lead screw 241, so that the fourth slider 242 drives the coil tray 13, the coil 12, the first slider 141, the second slider 142, and the second conductive rod 144 to move along the y direction.

It should be noted that, the driver 16 driving the fourth slider 242 may mean that the driver 16 is directly connected to the fourth slider 242 in a transmission manner. For example, the fourth slider 242 is coupled to the fourth lead screw 241 in a threaded manner, and when the driver 16 drives the fourth slider 242 to move along the fourth lead screw 241, the fourth slider 242 drives the fourth lead screw 241 to pivot. Alternatively, the driver 16 driving the fourth slider 242 may also mean that the driver 16 is directly in transmission connection with the fourth lead screw 241. For example, the fourth slider 242 is coupled to the fourth lead screw 241 in a threaded manner, and when the driver 16 drives the fourth lead screw 241 to pivot around its central axis, the fourth lead screw 241 drives the fourth slider 242 to translate along the x direction.

In the above embodiment, the third lead screw mechanism drives the coil 12 and the coil tray 13 to move along the x direction, and the fourth lead screw mechanism drives the coil 12 and the coil tray 13 to move along the y direction, so that the two lead screw mechanisms are adopted to respectively drive the coil 12 and the coil tray 13 to move, so that the coil 12 and the coil tray 13 move more stably, and the coil 12 and the coil tray 13 can be more accurately controlled to move to any position.

The conductive moving assembly 14 further includes a third link 233 and a fourth link 243. The third link 233 is parallel to the third lead screw 231, and the third slider 232 is slidably connected to the third link 233. When the actuator 16 drives the third lead screw 231 to pivot, the third slider 232 can be driven to move along the y direction, so that the third slider 232 can simultaneously translate along the third lead screw 231 and the third link 233. The third link 233 serves as a guide to guide the third slider 232 to translate in the y direction, so that the third slider 232 is prevented from deflecting around the third lead screw 231, and the movement of the coil tray 13 is more stable. Similarly, the fourth link 243 is parallel to the fourth lead screw 241, and the fourth slider 242 is slidably connected to the fourth link 243. When the driver 16 drives the fourth lead screw 241 to pivot, the fourth slider 242 may be driven to move along the x direction, so that the fourth slider 242 may simultaneously translate along the fourth lead screw 241 and the fourth connecting rod 243. The fourth link 243 serves as a guide to guide the fourth slider 242 to translate along the x-direction, so that the fourth slider 242 is prevented from deflecting around the fourth screw rod 241.

In the above embodiment, the circuit board 15, the third link 233, the first conductive rod 143, the coil 12, the second conductive rod 144, the fourth link 243 and the circuit board 15 are electrically connected in sequence to form a complete charging circuit.

In an embodiment of the present application, the first slider 212, the second slider 222, the third slider 232, and the fourth slider 242 may be conductive tee pieces to facilitate assembly and disassembly of the conductive moving assembly 14. Here, the second slider 222 may include two three-way pieces, such that the first conductive rod 143 is electrically connected to the second lead screw 221, and the second conductive rod 144 is electrically connected to the second link 223. Taking the first slider 212 as an example, the first slider 212 may have an L-shape or a T-shape, and a body thereof may be made of an insulating material. The first slider 212 is provided at the inside thereof with a conductive through hole for electrically connecting the first conductive rod 143 and the first link 213.

In order to reduce the on-resistance in the charging circuit, the surfaces of the first conductive rod 143 and the second conductive rod 144 may be coated with a conductive lubricating layer, so that the heat generation and energy consumption of the charging circuit may be reduced, and the wireless charging efficiency may be improved. The conductive lubricating layer may be specifically a conductive oil or a low-resistance paint or the like.

In addition, the circuit board 15, the first conductive rod 143, the first sliding member 141, the coil 12, the second sliding member 142, the second conductive rod 144, and the circuit board 15 are electrically connected in sequence to form a complete charging circuit, so that the lead connecting the coil 12 and the circuit board 15 does not need to be set to be too long, thereby preventing the lead of the coil 12 from being pulled and preventing the lead from crosstalk with the charging circuit after being powered on.
