[0001] This application relates to the field of wireless transmission technology, and in particular to a medical device, a plug-in box, and a wireless transmission system. Background Technology

[0002] To expand the functionality of electronic devices, expansion function plug-ins are typically installed. These plug-ins receive power from the electronic device and must perform tasks such as identification, handshake, and communication with it. Only after completing these tasks can the expansion function plug-in enable the configured functions on the electronic device.

[0003] In the prior art, electronic devices and expansion function plug-ins usually transmit electrical energy and signals through direct contact of electrical conductors. However, direct contact of electrical conductors is prone to poor electrical contact, deformation and damage, short circuits and leakage, resulting in low reliability and potential safety hazards when using expansion function plug-ins.

[0004] Therefore, how to solve the problem of low reliability and potential security risks between electronic devices and extended function plug-ins in the prior art is an urgent problem to be solved by those skilled in the art.

The medical device includes a first housing and a first circuit board, a first communication component, and an identification component disposed within the first housing. A receiving space is provided on one side of the first housing for accommodating a plug-in box. The first circuit board includes a first communication interface, an identification component interface, and a first control unit. The first control unit is electrically connected to both the first communication interface and the identification component interface. The first communication interface is also electrically connected to the first communication component, and the identification component interface is also electrically connected to the identification component. The identification component receives an identification wireless signal emitted by the plug-in box and converts the identification wireless signal into an identification electrical signal. The identification component then transmits the identification electrical signal to the first control unit, which identifies the type of the plug-in box based on the identification electrical signal. The first communication component receives a first electrical signal transmitted by the first control unit through the first communication interface, converts the first electrical signal into a first wireless signal, and transmits the first wireless signal to the plug-in box.

[0042] Please refer to Figure 1, which is a schematic diagram of the structure of a medical device and a plug-in box in the prior art. The plug-in box b can be assembled into the plug-in slot of the medical device a along a first direction 001, and can be detached from the plug-in slot of the medical device a along a second direction 002, wherein the first direction 001 and the second direction 002 are opposite. The medical device a includes an electrical contact a1, and the plug-in box b includes an electrical terminal b1 corresponding to the electrical contact a1. When the plug-in box b is assembled into the medical device a, the electrical terminal b1 contacts the electrical contact a1, thereby electrically connecting the plug-in box b and the medical device a, and thus allowing the transmission of electrical signals between the medical device a and the plug-in box b.

[0043] Because electrical contact a1 and terminal b1 are in direct contact, both need to be exposed. In actual use, the following problems may easily occur: Electrical contact a1 or terminal b1 may be deformed or damaged due to external forces, such as drops, collisions, or improper insertion / removal. Electrical contact a1 or terminal b1 may lose conductivity due to disinfection, cleaning, natural oxidation, aging, or corrosion.

Electrical contact a1 or terminal b1 may easily generate electric sparks during insertion / removal, posing a fire risk in flammable gas environments. Electrical contact a1 or terminal b1 may wear during insertion / removal, and when the wear reaches a certain level, poor electrical contact may easily occur between them. Mechanical wear and deformation of the insertion slot may cause misalignment between electrical contact a1 and terminal b1, resulting in a failure to make contact.

[0066] It should be noted that there are multiple identification elements 151 and at least one tag element 251, and the number of tag elements 251 is at most equal to the number of identification elements 151, that is, the number of tag elements 251 is less than or equal to the number of identification elements 151. The position of each tag element 251 corresponds to the position of one identification element 151. The identification element 151 receives the sub-tag wireless signal emitted by the tag element 251 whose position corresponds to it; it cannot receive the sub-tag wireless signal if there is no identification element 151 whose position corresponds to it. Therefore, different types of plug-in boxes 20 can make their tag components 25 emit different tag wireless signals by changing the number and position of the tag elements 251. For example, if there are three identification elements 151 and one tag element 251, the position of the tag element 251 can correspond to the position of any one of the three identification elements 151, so that the tag component 25 can emit three different tag wireless signals. For example, the number of identification elements 151 is three, and the number of tag elements 251 is two. The positions of the two tag elements 251 can correspond to the positions of any two of the three identification elements 151, so that the tagging component 25 can emit three different tagging wireless signals. Alternatively, the number of identification elements 151 is three, and the number of tag elements 251 is three. The positions of the three tag elements 251 correspond one-to-one with the positions of the three identification elements 151, so that the tagging component 25 can emit one type of tagging wireless signal.

[0067] In this application, the number of identification elements 151 is three, and the three identification elements 151 are arranged in a triangle, which reduces the area enclosed by the three identification elements 151 and helps to save the layout space of the identification component 25.

[0068] In other embodiments, the identification element 251 may also be a mechanical protrusion, and the recognition element 151 may be a touch-sensitive switch element. When the insertion box 20 is assembled into the medical device 10, the identification element 251 touches the recognition element 151, causing the recognition element 151 to emit a sub-identification wireless signal.

[0069] In this application, the first circuit board 13 further includes a power supply drive unit, which is electrically connected to the wireless power supply component 12 and the first control unit. The first control unit is used to control the power supply drive unit to supply power to the wireless power supply component 12. The wireless power supply component 12 is used to convert electrical energy into magnetic field energy, and the magnetic field energy is used to supply power to the plug-in box 20.

[0070] Specifically, please refer to Figure 4, which is a schematic diagram of the layer structure of the wireless power supply assembly shown in Figure 3. The wireless power supply assembly 12 includes a power supply coil element 310, a heat dissipation layer 320, an insulating layer 330, a magnetic shielding layer 340, a thermally conductive layer 350, and a fixing member 370. The heat dissipation layer 320, the insulating layer 330, the power supply coil element 310, the magnetic shielding layer 340, the thermally conductive layer 350, and the first circuit board 13 are sequentially stacked on the inner surface of the first housing 11 along a direction away from the X-axis. The fixing member 370 is disposed on the inner surface of the first housing 11 and is adjacent to the heat dissipation layer 320. The fixing member 370 extends towards the insulating layer 330 in a direction away from the heat dissipation layer 320 to the first circuit board 13, and the fixing member 370 is in contact with the first circuit board 13.

[0071] In an exemplary embodiment, a heat dissipation layer 320 is disposed on the inner surface of the first housing 11, and an insulating layer 330 is disposed on the surface of the heat dissipation layer 320 opposite to the connection between the heat dissipation layer 320 and the first housing 11. That is, the surface of the heat dissipation layer 320 connected to the first housing 11 and the surface of the heat dissipation layer 320 connected to the insulating layer 330 are two surfaces of the heat dissipation layer 320 that are opposite to each other. A power supply coil element 310 is disposed on the surface of the insulating layer 330 opposite to the heat dissipation layer 320. Heat emitted by the power supply coil element 310 is transferred to the heat dissipation layer 320 through the insulating layer 330, and the heat dissipation layer 320 transfers the heat to the first housing 11 for heat dissipation. The insulating layer 330 provides insulation between the heat dissipation layer 320 and the power supply coil element 310.

[0072] In some embodiments, the heat dissipation layer 320 is a graphene heat sink, and the insulating layer 330 is a high-temperature adhesive for polyimide film (PI film).

[0073] In some embodiments, the peripheral side surface of the heat dissipation layer 320 is aligned with the peripheral side surface of the insulating layer 330, and the periphery of the insulating layer 330 extends beyond the power supply coil element 310, meaning the periphery of the insulating layer 330 is not connected to the power supply coil element 310. The plane corresponding to the peripheral side surface of the heat dissipation layer 320 is perpendicular to the X-axis direction, and the plane corresponding to the peripheral side surface of the insulating layer 330 is also perpendicular to the X-axis direction.

[0074] In some embodiments, please refer to FIG5, which is a first top view schematic diagram of the coil element shown in FIG4. The power supply coil element 310 includes at least two power supply coils 311 stacked in the X-axis direction. Each power supply coil 311 includes a coil body 3111, and each coil body 3111 surrounds a hollow portion 3112. The coil bodies 3111 of any two power supply coils 311 partially overlap, and the hollow portions 3112 of any two power supply coils 311 are staggered. The power supply coil element 310 is used for magnetic coupling with the receiving coil so that the medical device 10 supplies power to the plug-in box 20. For example, FIG5 shows two power supply coils 311, which are defined as the first power supply coil 311a and the second power supply coil 311b, respectively. The second power supply coil 311b is stacked on top of the first power supply coil 311a. The coil body 3111 of the second power supply coil 311b partially covers the coil body 3111 of the first power supply coil 311a. The hollow portion 3112 of the first power supply coil 311a is not covered by the coil body 3111 of the second power supply coil 311b.

[0075] Understandably, by partially overlapping the coil bodies 3111 of at least two power supply coils 311, even if the plug-in box 20 moves a predetermined distance relative to the medical device 10, the receiving coil of the plug-in box 20 can still be aligned with the power supply coil element 310. This improves the alignment accuracy between the power supply coil element 310 and the receiving coil, thereby increasing the efficiency of power transmission from the medical device 10 to the plug-in box 20. Furthermore, it avoids the problem of overheating of the power supply coil element 310 caused by misalignment between the power supply coil element 310 and the receiving coil, which helps to extend the service life of the power supply coil element 310.

[0076] It should be noted that the overall shape of each power supply coil 311 is a ring, and each hollow part 3112 is circular. The central axis of each power supply coil 311 is parallel to the X-axis direction.

[0077] The power supply coil 311 can be a spiral coil, a planar coil, or an air coil, etc. This application does not limit the specific type of the power supply coil 311.

[0078] Please refer to Figure 6, which is a second top view schematic diagram of the coil element shown in Figure 4. Figure 6 shows three power supply coils 311, which are defined as the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c. The first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c are stacked sequentially, with each pair of coils stacked together. That is, the second power supply coil 311b is stacked on top of the first power supply coil 311a, and the third power supply coil 311c is stacked on top of the second power supply coil 311b and covers the first power supply coil 311a. The coil body 3111 of the second power supply coil 311b covers the coil body 3111 of the first power supply coil 311a, and the coil body 3111 of the third power supply coil 311c covers both the coil body 3111 of the second power supply coil 311b and the coil body 3111 of the first power supply coil 311a. The hollow portion 3112 of the first power supply coil 311a is not obstructed by the coil bodies 3111 of the second power supply coil 311b and the third power supply coil 311c, and the hollow portion 3112 of the third power supply coil 311c is not obstructed by the coil bodies 3111 of the first power supply coil 311a and the third power supply coil 311c. That is, in the X-axis direction, the hollow portion 3112 of the second power supply coil 311b is offset from the hollow portion 3112 of the first power supply coil 311a, and the hollow portion 3112 of the third power supply coil 311c is offset from the hollow portions 3112 of the first power supply coil 311a and the hollow portions 3112 of the second power supply coil 311b, respectively.

[0079] Understandably, since the hollow portions 3112 of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c are not blocked by the coil body 3111, the area where the three power supply coils 311 are located can be increased, which is beneficial to align the receiving coil of the plug-in box 20 with the power supply coil element 310.

[0080] For example, the lines connecting each pair of the center points of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c form a triangle, which can be an isosceles triangle or an equilateral triangle. The center points of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c are also their geometric centers.

[0081] Understandably, by forming a triangle with the lines connecting the center points of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c, the plug-in box 20 can move a preset distance in the plane formed by the Z-axis and Y-axis. The receiving coil of the plug-in box 20 can also be aligned with the power supply coil element 310, thereby improving the alignment accuracy between the power supply coil element 310 and the receiving coil.

[0082] In other embodiments, the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c may also be arranged sequentially along the Y-axis direction.

[0083] Please refer to Figure 7, which is a third top view schematic diagram of the coil element shown in Figure 4. In Figure 7, there are four power supply coils 311, which are defined as the first power supply coil 311a, the second power supply coil 311b, the third power supply coil 311c, and the fourth power supply coil 311d. These four coils are stacked sequentially. The lines connecting each pair of the center points of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c form triangles. For further descriptions of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c in Figure 7, please refer to the description of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c in Figure 6 above; they will not be repeated here.

[0084] In the stacking direction, the hollow portion 3112 of the fourth power supply coil 311d is located between the hollow portions 3112 of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c. That is, the orthographic projection of the hollow portion 3112 of the fourth power supply coil 311d in the X-axis direction is located between the orthographic projections of the hollow portions 3112 of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c in the X-axis direction.

[0085] Understandably, the fourth power supply coil 311d increases the magnetic field strength in the central region of the power supply coil element 310, thereby improving the efficiency of the medical device 10 in transmitting electrical energy to the plug box 20.

[0086] For example, in the X-axis direction, the hollow portion 3112 of the second power supply coil 311b is offset from the hollow portion 3112 of the first power supply coil 311a, and the hollow portion 3112 of the third power supply coil 311c is offset from both the hollow portions 3112 of the first power supply coil 311a and the hollow portions 3112 of the second power supply coil 311b. In the X-axis direction, the coil body 3111 of the fourth power supply coil 311d covers portions of the hollow portions 3112 of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c. That is, the coil body 3111 of the fourth power supply coil 311d covers the hollow portions 3112 of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c. The lines connecting each pair of the center points of the first power supply coil 311a, the second power supply coil 311b, and the third power supply coil 311c form an equilateral triangle, and the center point of the fourth power supply coil 311d is aligned with the geometric center of the equilateral triangle.

[0087] Understandably, the coil body 3111 of the fourth power supply coil 311d covers the hollow portion 3112 of the first power supply coil 311a, the second power supply coil 311b and the third power supply coil 311c, thereby maximizing the size of the fourth power supply coil 311d and further expanding the area with a stronger magnetic field, which is beneficial to improving the power transmission efficiency of the wireless power supply device.

[0088] Referring to Figures 5 to 7, the wireless power supply assembly 12 also includes at least two temperature sensing elements 380. These elements 380 are disposed on the power supply coil 311 and are used to detect the temperature of the power supply coil 311 in real time. The number of temperature sensing elements 380 is determined by the number of power supply coils 311, such that each power supply coil 311 is equipped with one temperature sensing element 380. For example, in Figure 5, there are two power supply coils 311 and two temperature sensing elements 380. In Figure 6, there are three power supply coils 311 and three temperature sensing elements 380. In Figure 7, there are four power supply coils 311 and four temperature sensing elements 380.

[0089] The temperature sensing element 380 can be a thermocouple temperature sensor, a resistive temperature sensor, or a thermistor, etc., and this application does not impose specific restrictions on it.

[0090] In some embodiments, referring to FIG4, a magnetic shielding layer 340 is disposed on the surface of the power supply coil element 310 facing away from the insulating layer 330, and the magnetic shielding layer 340 is connected to the power supply coil element 310. The magnetic shielding layer 340 is configured to shield the magnetic field generated by the power supply coil element 310, preventing the magnetic field generated by the power supply coil element 310 from affecting other components within the medical device 10. The magnetic shielding layer 340 is a high-permeability magnetic shielding sheet.

[0091] In an exemplary embodiment, the peripheral side surface of the magnetic shielding layer 340 is aligned with the peripheral side surface of the insulating layer 330. The plane corresponding to the peripheral side surface of the magnetic shielding layer 340 is perpendicular to the X-axis direction. The periphery of the magnetic shielding layer 340 extends beyond the power supply coil element 310, meaning that the periphery of the magnetic shielding layer 340 is not connected to the power supply coil element 310.

[0092] In some embodiments, referring to FIG4, a thermally conductive layer 350 is disposed on the surface of the magnetic shielding layer 340 facing away from the power supply coil element 310, and the thermally conductive layer 350 is connected to the magnetic shielding layer 340. Heat dissipated by the power supply coil element 310 is transferred to the thermally conductive layer 350 through the magnetic shielding layer 340, and the thermally conductive layer 350 conducts the heat to the first circuit board 13 to dissipate heat from the power supply coil element 310. The thermally conductive layer 350 may be thermally conductive silicone grease.

[0093] In an exemplary embodiment, the peripheral side surface of the thermally conductive layer 350 is aligned with the peripheral side surface of the insulating layer 330. The plane corresponding to the peripheral side surface of the thermally conductive layer 350 is perpendicular to the X-axis direction.

The surface of the fixing member 370 facing away from the first housing 11 is connected to the periphery of the first circuit board 13. The first circuit board 13 is detachably connected to the fixing member 370 to fix the heat dissipation layer 320, the insulating layer 330, the power supply coil element 310, the magnetic shielding layer 340, and the thermally conductive layer 350.

[0097] The number of fixing members 370 can be one, and the fixing member 370 is ring-shaped. The heat dissipation layer 320, the insulating layer 330, the power supply coil element 310, the magnetic shielding layer 340, and the heat-conducting layer 350 are all located inside the fixing member 370. The number of fixing members 370 can be two, and the two fixing members 370 are arranged opposite each other and spaced apart. The number of fixing members 370 can also be three, four, or other numbers. This application does not impose a specific limit on the number of fixing members 370, as long as the fixing members 370 can fix the first circuit board 13.

[0098] In an exemplary embodiment, referring to Figure 4, a first fixing hole penetrating the first circuit board 13 is provided on the periphery of the first circuit board 13, and a second fixing hole is provided on the surface of the fixing member 370 facing the first circuit board 13, and the second fixing hole is aligned with and communicates with the first fixing hole. The first circuit board 13 and the fixing member 370 are detachably connected by screws fitted into the first and second fixing holes. The number of first fixing holes should be greater than two, and the number of second fixing holes should also be greater than two.

[0099] In other embodiments, the first circuit board 13 and the fastener 370 can be detachably connected by a snap-fit ​​mechanism.

[0100] In some embodiments, referring to FIG4, the wireless power supply assembly 12 further includes a first socket 390, which is disposed on the surface of the first circuit board 13 opposite to the thermally conductive layer 350. The first socket 390 is electrically connected to the first circuit board 13, and the first circuit board 13 communicates with external devices and receives power through the first socket 390. The first socket 390 may be a Universal Serial Bus (USB) interface.

[0101] In this application, the wireless power receiving component 22 is electrically connected to the second circuit board 23. The wireless power receiving component 22 is used to receive magnetic field energy provided by the medical device 10 and convert the magnetic field energy into electrical energy, and to supply power to the second circuit board 23.

[0102] Specifically, please refer to Figure 8, which is a schematic diagram of the layer structure of the wireless power receiving component shown in Figure 3. The wireless power receiving component 22 includes a receiving coil 410, a heat dissipation element 420, an insulating element 430, a magnetic shielding element 440, a thermally conductive element 450, and an assembly 470. The heat dissipation element 420, the insulating element 430, the receiving coil 410, the magnetic shielding element 440, the thermally conductive element 450, and the second circuit board 23 are sequentially stacked on the inner surface of the second housing 21 along the X-axis direction.

The assembly 470 extends towards the second circuit board 23 in a direction away from the heat dissipation element 420 and is in contact with the second circuit board 23.

[0103] In an exemplary embodiment, a heat dissipation element 420 is disposed on the inner surface of the second housing 21, and an insulating element 430 is disposed on the surface of the heat dissipation element 420 opposite to the connection between the heat dissipation element 420 and the second housing 21. That is, the surface connecting the heat dissipation element 420 to the second housing 21 and the surface connecting the heat dissipation element 420 to the insulating element 430 are two surfaces of the heat dissipation element 420 that are opposite to each other. A current-receiving coil 410 is disposed on the surface of the insulating element 430 opposite to the heat dissipation element 420. Heat dissipated by the current-receiving coil 410 is transferred to the heat dissipation element 420 through the insulating element 430, and the heat dissipation element 420 transfers the heat to the second housing 21 for heat dissipation. The insulating element 430 provides insulation between the heat dissipation element 420 and the current-receiving coil 410.

[0104] In some embodiments, the heat dissipation element 420 is a graphene heat sink, and the insulating element 430 is a high-temperature adhesive for polyimide film (PI film).

[0105] In some embodiments, the peripheral side surface of the heat dissipation element 420 is aligned with the peripheral side surface of the insulating element 430, and the periphery of the insulating element 430 extends beyond the current receiving coil 410, meaning that the periphery of the insulating element 430 is not covered by the current receiving coil 410. The plane corresponding to the peripheral side surface of the heat dissipation element 420 is perpendicular to the X-axis direction, and the plane corresponding to the peripheral side surface of the insulating element 430 is also perpendicular to the X-axis direction.

[0106] Please refer to Figure 9, which is a top view of the receiving coil shown in Figure 8. There is one receiving coil 410. For a detailed description of the receiving coil 410, please refer to the description of the power supply coil 311; it will not be repeated here. The wireless receiving component 22 includes a temperature measuring element 480, which is disposed on the receiving coil 410 and is used to detect the temperature of the receiving coil 410 in real time. The temperature measuring element 480 can be a thermocouple temperature sensor, a resistive temperature sensor, or a thermistor, etc., and this application does not impose specific limitations on it.

The magnetic shielding element 440 is configured to shield the magnetic field generated by the receiving coil 410, preventing the magnetic field generated by the receiving coil 410 from affecting other components within the plug-in box 20. The magnetic shielding element 440 is a high-permeability magnetic shielding sheet.

[0108] In an exemplary embodiment, the peripheral side surface of the magnetic shielding element 440 is aligned with the peripheral side surface of the insulating element 430. The plane corresponding to the peripheral side surface of the magnetic shielding element 440 is perpendicular to the X-axis direction. The periphery of the magnetic shielding element 440 extends beyond the receiving coil 410, meaning that the periphery of the magnetic shielding element 440 is not connected to the receiving coil 410.

[0116] In other embodiments, the second circuit board 23 and the assembly 470 can be detachably connected by a snap-fit ​​mechanism.

[0117] It should be noted that the specific structural difference between the wireless power receiving component 22 and the wireless power supply component 12 is that the number of power receiving coils 410 in the wireless power receiving component 22 is different from the number of power supply coils 311 in the wireless power supply component 12. Specifically, the wireless power receiving component 22 has one power receiving coil, while the number of power supply coils 311 can be two, three, or four.

[0120] The first power converter 132 receives power voltage from an external power source through an external interface 133 and converts the power voltage into a first operating voltage. The first power converter 132 transmits the first operating voltage to the first control unit 131 to supply power to the first control unit 131. The first power converter 132 also transmits the first operating voltage to the temperature sensing element 380 through the temperature sensing element interface 138 to supply power to the temperature sensing element 380. Furthermore, the first power converter 132 transmits the first operating voltage to the identification component 15 through the identification component interface 137 to supply power to the identification component 15. Finally, the first power converter 132 transmits the first operating voltage to the first communication component 14 through the first communication interface 136 to supply power to the first communication component 14. Finally, the first power converter 132 transmits the first operating voltage to the power supply drive unit 134 to supply power to the power supply drive unit 134. The potential of the first operating voltage is lower than the potential of the power supply voltage.

[0121] In this application, the power supply driving unit 134 includes a wireless power supply driver 1341 and a coil full-bridge driver 1342. The wireless power supply driver 1341 converts a first operating voltage into a first driving voltage and transmits the first driving voltage to the coil full-bridge driver 1342. The coil full-bridge driver 1342 receives the first driving voltage and provides a first supply voltage to the power supply coil element 310 through the power supply coil interface 135 according to the first driving voltage. The power supply coil element 310 is magnetically coupled to the receiving coil 410 according to the first supply voltage, so that the medical device 10 supplies power to the plug-in box 20. The first driving voltage is a DC voltage, and the first supply voltage is an alternating voltage.

[0122] In some embodiments, the first control unit 131 is communicatively connected to the external interface 133, the wireless power supply driver 1341, the power supply coil interface 135, the first communication interface 136, and the temperature sensing element interface 138, respectively. The communication connection is used to transmit electrical signals and can be either wired or wireless; this application does not impose specific limitations on this.

[0123] The first control unit 131 transmits electrical signals bidirectionally with external devices via external interface 133, i.e., the first control unit 131 communicates with external devices in a full-duplex manner. The first control unit 131 sends a first control signal to the wireless power supply driver 1341 to control when the wireless power supply driver 1341 provides a first driving voltage to the coil full-bridge driver 1342 and to control the potential of the first driving voltage; that is, the first control unit 131 controls the timing and potential of the first driving voltage through the first control signal. The wireless power supply driver 1341 feeds back the timing and potential of the first driving voltage to the first control unit 131 in real time. The identification component 15 sends an identification electrical signal to the first control unit through the identification component interface 137. The first communication component 14 receives the first electrical signal sent by the first control unit 131 through the first communication interface 136, and sends a second electrical signal to the first control unit 131 through the first communication interface 136.

[0124] In this application, the temperature sensing element 380 sends a temperature signal to the first control unit 131 based on the temperature of the power supply coil 311. The first control unit 131 receives the temperature signal and adjusts the timing and potential of the first driving voltage according to the temperature signal. For example, if the temperature of the power supply coil 311 is higher than a preset temperature, causing the potential of the temperature signal emitted by the temperature sensing element 380 to be lower than a preset potential, the first control unit 131 controls the wireless power supply driver 1341 to stop providing the first driving voltage to the coil full-bridge driver 1342 based on the temperature signal with a potential lower than the preset potential; that is, the first control unit 131 controls the disconnection of the power supply coil 311 from the power supply. If the temperature of the power supply coil 311 is lower than a preset temperature, causing the potential of the temperature signal emitted by the temperature sensing element 380 to be higher than the preset potential, the first control unit 131 controls the wireless power supply driver 1341 to provide the first driving voltage to the coil full-bridge driver 1342 based on the temperature signal with a potential higher than the preset potential; that is, the first control unit 131 controls the connection of the power supply coil 311 to the power supply.

[0125] It should be noted that the first control unit 131 can selectively control the connection or disconnection of the power supply coil 311 with the power source based on the temperature of the power supply coil 311. Specifically, when the temperature of the power supply coil 311 exceeds a preset temperature, the first control unit 131 disconnects the power supply coil 311 from the power source. By monitoring the temperature of each power supply coil 311 in real time, the power supply coil 311 is disconnected from the power source when its temperature exceeds the preset temperature, thus preventing the power supply coil 311 from overheating and burning out.

[0126] If the temperature of any one of the multiple power supply coils 311 exceeds the preset temperature, the first control unit 131 will disconnect all the power supply coils 311 from the power supply.

[0127] In some embodiments, after the power supply coil element 310 is magnetically coupled to the power receiving coil 410, the power supply coil interface 135 feeds back the timing and potential of the first power supply voltage to the first control unit 131.

The wireless power receiver 234 receives the second supply voltage and converts it into a second driving voltage, which is then transmitted to the second power converter 232. The second driving voltage is a DC voltage, while the second supply voltage is an alternating voltage. The second power converter 232 receives the second driving voltage and converts it into a second operating voltage. The second power converter 232 transmits the second operating voltage to the second control unit 231 to supply power to the second control unit 231. It also transmits the second operating voltage to the power component 26 via the power component interface 236, to the second communication component 24 via the second communication interface 235, and to the temperature measuring element 480 via the temperature measuring element interface 238 to supply power to the temperature measuring element 480.

[0132] The second control unit 231 sends a second control signal to the wireless power supply receiver 234 to control the timing and potential of the second driving voltage converted by the wireless power supply driver 1341. The wireless power supply receiver 234 feeds back the timing and potential of the second driving voltage to the second control unit 231 in real time. The second control unit 231 transmits electrical signals bidirectionally with the power supply component 26 through the power supply component interface 236, i.e., the second control unit 231 and the power supply component 26 communicate in full-duplex mode.
