[0004] The problem addressed by this invention is how to improve the charging safety and reliability of robots.

[0005] To address the above problems, this invention provides a wireless charging receiver, a wireless charging system, and a robot.

[0006] In a first aspect, the present invention provides a wireless charging receiver for wirelessly connecting to a wireless charging transmitter of a wireless charging system. The wireless charging transmitter includes a transmitting unit and a first magnetic structure, the first magnetic structure being connected to the transmitting unit. The wireless charging receiver includes: A housing for mounting on the robot's torso; A receiving unit is installed inside the housing. The receiving unit is used to receive the alternating magnetic field generated by the transmitting unit and convert the alternating magnetic field into electrical energy. The receiving unit is used to be electrically connected to the robot's battery pack to wirelessly charge the battery pack. A second magnetic structure is connected to the outer shell and is used to magnetically connect with the first magnetic structure. When the second magnetic structure is magnetically connected with the first magnetic structure, the receiving unit and the transmitting unit are aligned.

[0007] Optionally, the housing includes a first housing and a second housing, the first housing and the second housing together forming the housing with a receiving cavity, and the receiving unit is installed in the receiving cavity of the housing.

[0008] Optionally, the first housing is provided with a first mounting position and a second mounting position, and the receiving unit includes a receiving coil and a receiving control box. The receiving control box is fixedly installed at the first mounting position, and the receiving coil is fixedly installed at the second mounting position. The receiving coil is used for wireless connection with the transmitting unit, and the receiving coil is used for electrical connection with the battery pack through the receiving control box.

[0009] Optionally, the receiving control box and the receiving coil are arranged along the mating surface of the first housing and the second housing.

[0010] Optionally, the second magnetic structure includes a third magnetic block and a fourth magnetic block spaced apart and having opposite polarities. The first housing is provided with a third mounting groove and a fourth mounting groove. The third magnetic block is embedded in the third mounting groove, and the fourth magnetic block is embedded in the fourth mounting groove.

[0011] Optionally, the second magnetic structure includes at least one pair of third magnetic blocks and at least one pair of fourth magnetic blocks, wherein the two third magnetic blocks of the at least one pair are located at opposite ends of the spaced arrangement direction of the two fourth magnetic blocks of the at least one pair.

[0012] Optionally, the wireless charging receiver further includes a heat insulation plate structure, which is located between the receiving unit and the battery pack, and is fixedly connected to the first housing and / or the second housing.

[0013] Optionally, the receiving unit is electrically connected to the battery pack via a connecting wire, and the heat insulation plate structure is provided with a clearance structure for the connecting wire to pass through.

[0014] Optionally, the receiving unit further includes a cooling fan and cooling fins, the receiving coil and the receiving control box are respectively thermally connected to the cooling fins, and the cooling fan is used to blow air onto the cooling fins to dissipate heat.

[0015] Optionally, the surface of the first housing away from the second housing has a planar structure, the planar structure being used to fit with the transmitting unit, and the second magnetic structure being disposed on the inner side of the planar structure.

[0016] Optionally, the first housing and / or the second housing are provided with heat dissipation holes at a position corresponding to the receiving unit.

[0017] Secondly, the present invention provides a wireless charging system, including a wireless charging transmitter and a wireless charging receiver as described above. The second magnetic structure of the wireless charging receiver is used to magnetically connect with the first magnetic structure of the wireless charging transmitter. Through the magnetic attraction between the second magnetic structure and the first magnetic structure, the transmitting unit connected to the first magnetic structure is moved to achieve the positioning and alignment of the transmitting unit and the receiving unit.

[0018] Thirdly, the present invention provides a robot including a torso, a battery pack, and a wireless charging receiver as described above.

[0019] The beneficial effects of the wireless charging receiver, wireless charging system, and robot of the present invention are: The wireless charging receiver mainly includes a shell, a receiving unit, and a second magnetic structure. The receiving unit is installed inside the shell to protect it.

[0020] When the robot needs to perform charging operations, it can move towards the wireless charging transmitter. Since the receiving unit and the second magnetic structure are mounted on the robot's body through the shell, when the distance between the second magnetic structure and the first magnetic structure is reduced to a certain extent, the second magnetic structure and the first magnetic structure are connected by magnetism. This enables the receiving unit of the wireless charging receiver to be quickly positioned and aligned with the transmitting unit of the wireless charging transmitter of the wireless charging system without human intervention, thus reducing labor costs.

[0021] The wireless charging transmitter also includes a control unit. The input and output terminals of the control unit are electrically connected to the power supply and the transmitting unit, respectively. The control unit converts the AC power supplied by the power supply into high-frequency AC power and transmits it to the transmitting unit. The transmitting unit can convert the high-frequency AC power output by the control unit into an alternating magnetic field. After the receiving unit and the transmitting unit are close together and aligned, the receiving unit can receive the alternating magnetic field emitted by the transmitting unit, convert it into AC current, and then into DC current. The receiving unit is used to connect to the battery pack, thereby enabling wireless charging of the robot's battery pack. In short, compared with related technologies, where wired charging piles for robot charging can cause electrical sparks or poor contact, this invention can wirelessly charge the robot by using a wireless charging receiver and a wireless charging transmitter. This replaces the method of plugging a charging gun into the robot's charging interface in related technologies, which not only reduces the risk of fire and electric shock, ensuring the robot's charging safety and reliability and extending its service life, but also eliminates the need for manual intervention, improving the convenience of charging the robot. In addition, by using the magnetic connection between the wireless charging receiver and the wireless charging transmitter to achieve coupling between the receiving unit and the transmitting unit, the efficiency and accuracy of the wireless coupling connection process can be effectively improved. This is beneficial for robots to perform automatic wireless charging without human intervention, thus reducing labor costs. Attached Figure Description

[0028] To address the problems existing in the aforementioned related technologies, this embodiment provides a wireless charging receiver, a wireless charging system, and a robot.

[0029] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a wireless charging receiver 200, which is used to wirelessly connect to a wireless charging transmitter 100 of a wireless charging system. The wireless charging transmitter 100 includes a transmitting unit 120 and a first magnetic structure 130, the first magnetic structure 130 being connected to the transmitting unit 120; the wireless charging receiver 200 includes: Housing 210, which is used to be mounted on the robot's torso 400; A receiving unit 220 is installed inside the housing 210. The receiving unit 220 is used to receive the alternating magnetic field generated by the transmitting unit 120 and convert the alternating magnetic field into electrical energy. The receiving unit 220 is used to be electrically connected to the battery pack 500 to wirelessly charge the battery pack 500. The second magnetic structure 230 is connected to the outer shell 210 and is used to magnetically connect with the first magnetic structure 130; wherein, when the second magnetic structure 230 is magnetically connected with the first magnetic structure 130, the receiving unit and the transmitting unit 120 are positioned and aligned.

[0030] Specifically, the outer shell 210 can be installed on the robot's torso 400 by at least one method such as a snap-fit ​​or bolt fastener, wherein the torso 400 can be the robot's chest or abdomen, etc.

[0031] Combination Figure 3 As shown, the wireless charging transmitter 100 also includes a control unit 110, a first wire, and a second wire. The input terminal of the control unit 110 can be electrically connected to a power source via the first wire. The control unit 110 is used to convert the DC or AC power supplied by the power source into high-frequency current. The output terminal of the control unit 110 can be electrically connected to a transmitter 120 via the second wire. The transmitter 120 is used to convert the high-frequency AC power supplied by the control unit 110 into an alternating magnetic field. The control unit 110 can be mounted on a fixing member 300 of the wireless charging system. The fixing member 300 can be a structure such as a column or a wall.

[0032] The receiving unit 220 is coupled to the transmitting unit 120. The receiving unit 220 is used to receive the alternating magnetic field generated by the transmitting unit 120 and convert the alternating magnetic field into electrical energy to wirelessly charge the battery pack 500.

[0033] The second magnetic structure 230 is connected to the outer casing 210. This can be understood as the second magnetic structure 230 being installed inside the outer casing 210 or outside the outer casing 210.

[0034] The second magnetic structure 230 has opposite surface magnetism to the first magnetic structure 130, which can achieve magnetic connection between the two.

[0035] In this embodiment, the wireless charging receiver 200 mainly includes a housing 210, a receiving unit 220, and a second magnetic structure 230. The receiving unit 220 is installed inside the housing 210 to protect the receiving unit 220 through the housing 210.

[0036] When the robot needs to perform charging operations, it can move towards the wireless charging transmitter 100. Since the receiving unit 220 and the second magnetic structure 230 are mounted on the robot's body 400 through the outer shell 210, when the distance between the second magnetic structure 230 and the first magnetic structure 130 is reduced to a certain extent, the second magnetic structure 230 and the first magnetic structure 130 are connected by magnetism. This enables the receiving unit 220 of the wireless charging receiver 200 and the transmitting unit 120 of the wireless charging transmitter 100 of the wireless charging system to be quickly positioned and aligned without human intervention, thus reducing labor costs.

[0037] The wireless charging transmitter 100 also includes a control unit 110. The input and output terminals of the control unit 110 are electrically connected to the power supply and the transmitter unit 120, respectively. The control unit 110 converts the AC power supplied by the power supply into high-frequency AC power and transmits it to the transmitter unit 120. The transmitter unit 120 converts the high-frequency AC power output by the control unit 110 into an alternating magnetic field. After the receiver unit 220 approaches or is aligned with the transmitter unit 120, it receives the alternating magnetic field emitted by the transmitter unit 120, converts it first into AC current, and then into DC current. The receiver unit 220 is then used to communicate with the battery pack 5. The device features a 00 electrical connection, enabling wireless charging of the robot's battery pack 500. In short, compared to related technologies where wired charging piles cause electrical sparks or poor contact, this invention uses a wireless charging receiver 200 and a wireless charging transmitter 100 to wirelessly charge the robot. This replaces the method of plugging a charging gun into the robot's charging interface, reducing the risk of fire and electric shock, ensuring charging safety and reliability, extending the robot's lifespan, and eliminating the need for manual intervention, thus improving charging convenience. Furthermore, the magnetic connection between the wireless charging receiver 200 and the wireless charging transmitter to couple the receiver unit 220 and the transmitter unit 120 effectively improves the efficiency and accuracy of the wireless coupling process, facilitating automatic wireless charging of the robot without human intervention and reducing labor costs.

[0038] Optionally, the housing 210 may adopt the following structure, combined with Figure 2 As shown, the outer shell 210 includes a first shell 211 and a second shell 212. The first shell 211 and the second shell 212 together form the outer shell 210 with a receiving cavity. The receiving unit 220 is installed in the receiving cavity of the outer shell 210.

[0039] Specifically, the first housing 211 and the second housing 212 can be connected in the following manner: for example, after the receiving unit 220 and the second magnetic structure 230 are installed in the outer shell 210 with a receiving cavity formed by the first housing 211 and the second housing 212, the first housing 211 and the second housing 212 can be connected and fastened by bolts.

[0040] In this optional embodiment, since the receiving unit 220 is installed in the receiving cavity of the housing 210, the receiving unit 220 is encapsulated by the housing 210, thereby achieving safe protection of the receiving unit 220.

[0041] Optionally, combined Figures 4 to 6 As shown, the first housing 211 is provided with a first mounting position 2115 and a second mounting position 2116. The receiving unit 220 includes a receiving coil 221 and a receiving control box 222. The receiving control box 222 is fixedly installed at the first mounting position 2115, and the receiving coil 221 is fixedly installed at the second mounting position 2116. The receiving coil 221 is used for wireless connection with the transmitting unit 120, and the receiving coil 221 is used for electrical connection with the battery pack 500 through the receiving control box 222.

[0042] Specifically, both the first mounting position 2115 and the second mounting position 2116 can be mounting areas.

[0043] The receiving coil 221 is wirelessly connected to the transmitting unit 120, the receiving coil 221 is electrically connected to the input terminal of the receiving control box 222, and the output terminal of the receiving control box 222 is electrically connected to the battery pack 500.

[0044] The receiver control box 222 may employ a receiver circuit of the prior art, which is used to convert the alternating magnetic field provided by the transmitting unit 120 received by the receiving coil 221 into alternating current and then into direct current for charging the battery pack 500.

[0045] In this optional embodiment, since the receiving control box 222 and the receiving coil 221 are respectively installed at the first mounting position 2115 and the second mounting position 2116 of the first housing 211, in other words, the receiving control box 222 and the receiving coil 221 are separately disposed in the first housing 211, thereby reducing the degree of heat concentration.

[0046] The transmitting unit 120 can wirelessly transmit the generated alternating magnetic field to the receiving coil 221. The receiving coil 221 is used to transmit the received alternating magnetic field to the receiving control box 222, so that the receiving control box 222 can first convert the received alternating magnetic field into alternating current and then into direct current, so as to wirelessly charge the battery pack 500 through the direct current.

[0047] Optionally, combined Figure 5 and Figure 6 As shown, the receiving control box 222 and the receiving coil 221 are arranged along the mating surface of the first housing 211 and the second housing 212.

[0048] Specifically, the mating surfaces of the first housing 211 and the second housing 212 can be... Figure 4 The plane formed by the X-axis and Z-axis in the coordinate system is parallel, and the arrangement direction of the receiving control box 222 and the receiving coil 221 can be parallel to... Figure 4 The Z-axis in the coordinate system is parallel to the direction of the coordinate system, i.e., it is set vertically; or, it can be parallel to the direction of the coordinate system. Figure 4 The X-axis in the coordinate system is parallel, that is, it is set along the width direction of the outer shell 210.

[0049] In this optional embodiment, since the receiving control box 222 and the receiving coil 221 are arranged along the mating surface of the first housing 211 and the second housing 212, in other words, they can be arranged along the extension direction or width direction of the outer shell 210, thereby not only reducing the overall thickness of the wireless charging receiver 200, but also reducing the heat concentration generated by the receiving control box 222 and the receiving coil 221 during operation.

[0050] Optionally, combined Figure 2 As shown, the second magnetic structure 230 includes a third magnetic block 231 and a fourth magnetic block 232 that are spaced apart and have opposite polarities. The first housing 211 is provided with a third mounting groove 2111 and a fourth mounting groove 2112. The third magnetic block 231 is embedded in the third mounting groove 2111, and the fourth magnetic block 232 is embedded in the fourth mounting groove 2112.

[0051] Specifically, the surface area of ​​the larger surface of the third magnetic block 231 can be smaller than the area of ​​the third mounting groove 2111 to ensure that the third magnetic block 231 can be smoothly installed in the third mounting groove 2111; the surface area of ​​the larger surface of the fourth magnetic block 232 can be smaller than the area of ​​the fourth mounting groove 2112 to ensure that the fourth magnetic block 232 can be smoothly installed in the fourth mounting groove 2112.

[0052] Combination Figure 9 As shown, the transmitting unit 120 includes a first mounting box 121 and a transmitting coil 122. The transmitting coil 122 and the first magnetic structure 130 can be mounted in the first mounting box 121 in the following manner: for example, a first mounting part 1211 and a second mounting part 1212 are provided in the first mounting box 121. The transmitting coil 122 can be mounted at the first mounting part 1211, and the first magnetic structure 130 can be mounted at the second mounting part 1212.

[0053] The first mounting portion 1211 and the second mounting portion 1212 may be a groove structure, a through-hole structure, or the like, disposed within the first mounting box 121. The first magnetic structure 130 may include a first magnetic block 131 and a second magnetic block 132, which may be installed in the second mounting portion 1212 at different locations.

[0054] The first magnetic block 131 and the third magnetic block 231 are positioned correspondingly and have opposite magnetic properties; the second magnetic block 132 and the fourth magnetic block 232 are positioned correspondingly and have opposite magnetic properties.

[0055] In this optional embodiment, since the third magnetic block 231 and the fourth magnetic block 232 are respectively installed in the third mounting groove 2111 and the fourth mounting groove 2112 of the first housing 211, the third magnetic block 231 and the fourth magnetic block 232 can be fixedly installed respectively. Furthermore, as the receiving unit approaches the transmitting unit, the third magnetic block 231 of the second magnetic structure is magnetically connected to the first magnetic block 131 of the first magnetic structure, and the fourth magnetic block 232 of the second magnetic structure is magnetically connected to the second magnetic block 132 of the first magnetic structure.

[0056] Optionally, combined Figure 2 and Figure 4 As shown, the second magnetic structure 230 includes at least two third magnetic blocks 231 and at least two fourth magnetic blocks 232, with at least one pair of the two third magnetic blocks 231 located at both ends of the spaced arrangement direction of the at least one pair of the two fourth magnetic blocks 232.

[0057] Specifically, the number of third magnetic blocks 231 can be less than or equal to the number of third mounting slots 2111; similarly, the number of fourth magnetic blocks 232 can be less than or equal to the number of fourth mounting slots 2112. Figure 2 and Figure 4 In the first housing 211, the second magnetic structure 230 may include two third magnetic blocks 231 and two fourth magnetic blocks 232. The two third magnetic blocks 231 are respectively installed in the third mounting slots 2111 at two different positions of the first housing 211, and the two fourth magnetic blocks 232 are respectively installed in the fourth mounting slots 2112 at two different positions of the first housing 211.

[0058] Combination Figure 2 As shown, at least two of the fourth magnetic blocks 232 are located at both ends of the spacing direction of at least two of the third magnetic blocks 231. This can be understood as the spacing direction of at least two third magnetic blocks 231 being the same as the spacing direction of at least two fourth magnetic blocks 232, and both being... Figure 4The coordinate system is parallel to the X-axis, and the two third magnetic blocks 231 are distributed at both ends of the spacing direction of the two fourth magnetic blocks 232. Similarly, the two first magnetic blocks 131 can be set at both ends of the spacing direction of the two second magnetic blocks 132.

[0059] The number of the first magnetic block 131 matches the number of the third magnetic block 231, and their polarities are opposite; the number of the second magnetic block 132 matches the number of the fourth magnetic block 232, and their polarities are opposite.

[0060] In this optional embodiment, the two third magnetic blocks 231 are located at both ends of the spaced arrangement direction of the two fourth magnetic blocks 232, and the two first magnetic blocks 131 can be disposed at both ends of the spaced arrangement direction of the two second magnetic blocks 132. The first magnetic blocks 131 are magnetically connected to the third magnetic blocks 231, and the second magnetic blocks 132 are magnetically connected to the fourth magnetic blocks 232. This increases the magnetic adsorption range of the second magnetic structure 230 of the wireless charging receiver 200 and the first magnetic structure 130 of the wireless charging transmitter 100, while ensuring that the second magnetic structure 230 and the first magnetic structure 130 have only one definite docking position, thereby improving the alignment accuracy of the receiver unit 220 and the transmitter unit 120.

[0061] Optionally, combined Figure 2 and Figure 7 As shown, the wireless charging receiver 200 also includes a heat insulation plate structure 240, which is located between the receiving unit 220 and the battery pack 500. The heat insulation plate structure 240 is fixedly connected to the first housing 211 and / or the second housing 212.

[0062] Specifically, the receiving unit 220 and the battery pack 500 can be located on opposite sides of the heat insulation structure 240.

[0063] The heat insulation plate structure 240 is fixedly connected to the first housing 211 and / or the second housing 212. This can be understood as the heat insulation plate structure 240 being fixedly connected to the first housing 211, or the heat insulation plate structure 240 being fixedly connected to the second housing 212, or different parts of the heat insulation plate structure 240 being fixedly connected to the first housing 211 and the second housing 212.

[0064] The heat insulation plate structure 240 is fixedly connected to the first shell 211 and / or the second shell 212 by means of adhesive, fasteners, snaps, etc.

[0065] In this optional embodiment, by providing a heat insulation plate structure 240 between the receiving unit 220 and the battery pack 500, the heat generated by the receiving unit 220 and the battery pack 500 during operation can be separated, effectively preventing the heat from concentrating and mixing on both sides of the heat insulation plate structure 240 or flowing between them, thereby appropriately extending the service life of the wireless charging receiver 200. Since the heat insulation plate structure 240 is fixedly connected to the first housing 211 and / or the second housing 212, the heat insulation plate structure 240 can be prevented from shaking or shifting relative to the outer shell 210, thereby improving the assembly stability of both.

[0066] Optionally, combined Figure 2 As shown, the receiving unit 220 is electrically connected to the battery pack 500 via a connecting wire, and the heat insulation plate structure 240 is provided with a clearance structure 241 for the connecting wire to pass through.

[0067] Specifically, the receiver control box 222 in the receiver unit 220 can be electrically connected to the battery pack 500 via connecting wires.

[0068] An avoidance structure 241 may be provided on the outer circumferential edge of the insulation structure 240, such as the top edge.

[0069] The avoidance structure 241 can be a notch structure.

[0070] In this optional embodiment, by providing an obstacle avoidance structure 241 on the heat insulation plate structure 240, it is possible for the connecting wires between the receiving control box 222 of the receiving unit 220 and the battery pack 500 to pass smoothly.

[0071] Optionally, combined Figure 5 and Figure 6 As shown, the receiving unit 220 also includes a cooling fan 223 and a heat dissipation fin 224. The receiving coil 221 and the receiving control box 222 are respectively thermally connected to the heat dissipation fin 224. The cooling fan 223 is used to blow air to the heat dissipation fin 224 to dissipate heat.

[0072] Specifically, the receiving control box 222 and the receiving coil 221 can be directly installed inside the first housing 211, or the receiving unit 220 may also include a mounting base, through which the receiving control box 222 and the receiving coil 221 can be indirectly installed inside the first housing 211.

[0073] The receiving unit 220 may include a heat sink 224, and the receiving coil 221 and the receiving control box 222 are thermally connected to different parts of the same heat sink 224 by means of bonding or integral molding; or, the receiving unit 220 may include two heat sinks 224, and the receiving coil 221 and the receiving control box 222 are thermally connected to the two heat sinks 224 by means of bonding or integral molding.

[0074] Cooling fans 223 can be installed on the heat dissipation fins 224 at positions corresponding to the receiving coil 221 and the receiving control box 222, respectively.

[0075] In this optional embodiment, since the receiving coil 221 and the receiving control box 222 are thermally connected to the heat dissipation fins 224, the heat dissipation area of ​​the receiving coil 221 and the receiving control box 222 can be increased through the heat dissipation fins 224, thereby improving the heat dissipation effect of the receiving coil 221 and the receiving control box 222. Since cooling fans 223 are installed on the heat dissipation fins 224 at positions corresponding to the receiving coil 221 and the receiving control box 222, the cooling fans 223 are used to blow air onto the heat dissipation fins 224 to dissipate heat, thereby accelerating the flow speed of hot air on the surface of the heat dissipation fins 224, further improving the heat dissipation effect of the receiving coil 221 and the receiving control box 222.

[0076] Optionally, combined Figure 7 and Figure 8 As shown, the surface of the first housing 211 away from the second housing 212 has a planar structure 2113, the planar structure 2113 is used to fit with the transmitting unit 120, and the second magnetic structure 230 is disposed on the inner side of the planar structure 2113.

[0077] Specifically, the surface of the first housing 211 that is away from the second housing 212 can also be understood as the surface of the first housing 211 that is close to the transmitting unit 120.

[0078] The planar structure 2113 may be located within the region of the outer circumferential edge of the first shell 211.

[0079] The second magnetic structure 230 can be positioned opposite to and attached to the planar structure 2113 or spaced apart.

[0080] In this optional embodiment, since the surface of the first housing 211 away from the second housing 212 has a planar structure 2113, when the receiving unit 220 disposed in the housing 210 is magnetically attracted to the first magnetic structure 130 of the wireless charging transmitter 100 through the second magnetic structure 230, the contact area between the receiving unit 220 and the transmitter 120 through the housing 210 can be increased, thereby improving the wireless charging reliability of both.

[0081] Optionally, combined Figure 4 and Figure 8 As shown, the first housing 211 and / or the second housing 212 are provided with heat dissipation hole structures 2114 at positions corresponding to the receiving unit 220.

[0082] Specifically, a heat dissipation hole structure 2114 may be provided only on the first housing 211 at the position corresponding to the receiving unit 220 (receiving control box 222 and receiving coil 221), or a heat dissipation hole structure 2114 may be provided only on the second housing 212 at the position corresponding to the receiving unit 220 (receiving control box 222 and receiving coil 221), or a heat dissipation hole structure 2114 may be provided on both the first housing 211 and the second housing 212 at the position corresponding to the receiving unit 220 (receiving control box 222 and receiving coil 221).

[0083] In this optional embodiment, heat dissipation hole structures 2114 are provided at positions corresponding to the receiving unit 220 in the first housing 211 and / or the second housing 212, so that the heat generated by the receiving control box 222 and the receiving coil 221 of the receiving unit 220 during operation can be dissipated from their respective heat dissipation hole structures 2114. Furthermore, since heat dissipation fins 224 and cooling fans 223 are provided on the end faces of the receiving control box 222 and the receiving coil 221, the heat generated by the receiving control box 222 and the receiving coil 221 is first conducted to the heat dissipation fins 224 for initial heat dissipation under the action of the cooling fan 223, and then quickly flows out from their respective heat dissipation hole structures 2114 under the action of the cooling fan 223, further improving the heat dissipation effect of both.

[0084] This invention provides a wireless charging system, including a wireless charging transmitter 100 and a wireless charging receiver 200 as described in the above embodiment. The second magnetic structure 230 of the wireless charging receiver 200 is used to magnetically connect with the first magnetic structure 130 of the wireless charging transmitter 100. Through the magnetic attraction between the second magnetic structure 230 and the first magnetic structure 130, the transmitter unit 120 connected to the first magnetic structure 130 is moved to achieve positioning and alignment between the transmitter unit 120 and the receiver unit 220.

[0085] Specifically, in combination Figure 3 and Figure 10 As shown, the wireless charging system also includes a fixing member 300, and the control unit 110 of the wireless charging transmitter 100 is fixedly connected to the fixing member 300. The fixing member 300 can be a column or a wall.

[0086] The control unit 110 may employ existing technology control circuits or electronic devices capable of converting DC or AC power supplied by the power source into high-frequency current. The receiver control box 222 may employ existing technology control circuits or electronic devices capable of first converting the alternating magnetic field provided by the transmitting unit 120 into AC current and then into DC current.

[0087] The wireless charging transmitter 100 also includes a first connecting line 140 and a second connecting line 150. The two ends of the first connecting line 140 are used to connect the fixing member 300 and the transmitting unit 120 respectively. The first connecting line 140 can be arranged horizontally or at a small angle to the horizontal plane. The second connecting line 150 is arranged vertically. The top and bottom ends of the second connecting line 150 are used to connect the fixing member 300 and the transmitting unit 120 respectively.

[0088] When the robot needs to be charged and moves close to the transmitting unit 120, the second magnetic structure 230 of the wireless charging receiver 200 and the first magnetic structure 130 of the wireless charging transmitter 100 are attracted by their magnetism, so as to drive the transmitting unit 120 connected to the first magnetic structure 130 to move towards the receiving unit 220, so as to adjust the relative position of the transmitting unit 120 and the receiving unit 220 until the receiving unit 220 and the transmitting unit 120 are quickly aligned. The receiving unit 220 can receive the alternating magnetic field emitted by the transmitting unit 120, and convert it into alternating current and then into direct current, thereby realizing the wireless charging operation of the robot's battery pack 500.

[0089] The first connecting line 140 is in a relaxed state before and during the charging phase of the robot's battery pack 500. When the robot is fully charged and leaves the transmitting unit 120, the first connecting line 140 is in a taut state. This ensures that when the robot moves away from the transmitting unit 120, the transmitting unit 120 and the first magnetic structure 130 in the wireless charging transmitter 100 can be easily separated from the second magnetic structure 230 and the receiving unit 220 in the wireless charging receiver 200. This eliminates the need for manual separation of the transmitting unit 120 and the receiving unit 220, saving labor costs.

[0090] The transmitting unit 120 can be connected to the fixing member 300 via the second connecting line 150 to enable the suspending or lifting of the transmitting unit 120. This is equivalent to the first magnetic structure 130 set on the transmitting unit 120 being able to move the transmitting unit 120 under the magnetic attraction of the second magnetic structure 230 of the wireless charging receiver 200, thereby enabling the movable setting of the transmitting unit 120. This facilitates the rapid alignment of the robot's receiver 220 with the transmitting unit 120 and the charging operation. This embodiment is applicable to robots, such as humanoid robots, where the wireless charging receiver 200 has a certain setting height. The suspension or lifting height of the transmitting unit 120 can be matched with the height of the wireless charging receiver 200 of the robot, such as the humanoid robot.

[0091] The advantages of the wireless charging system in this embodiment over the prior art are the same as those of the wireless charging receiver 200 described above, and will not be repeated here.

[0092] The present invention provides a robot including a torso 400, a battery pack 500, and a wireless charging receiver 200 as described in the above embodiment.

[0093] Specifically, the robot can be a humanoid robot or a quadruped robot (such as a robot dog).

[0094] The advantages of the robot in this embodiment over the prior art are the same as those of the wireless charging receiver 200 described above, and will not be repeated here.

[0095] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
