[0004] The problem solved by this invention is how to reduce the accuracy requirements for robot movement during charging by using a wireless charging transmitter.

[0005] To address the aforementioned problems, this utility model provides a wireless charging transmitter, a wireless charging system, and a robot.

[0006] In a first aspect, this utility model provides a wireless charging transmitter for wirelessly connecting to a receiving module. The wireless charging transmitter includes: The control unit has an input terminal for connecting to a power source and an output terminal for outputting high-frequency alternating current. A transmitting unit, which is electrically connected to the output terminal of the control unit, is used to convert the high-frequency alternating current provided by the control unit into an alternating magnetic field. A first magnetic component is connected to the transmitting unit. The receiving module includes a receiving unit and a mating component. The receiving unit is used to receive the alternating magnetic field generated by the transmitting unit. The mating component is used to magnetically connect with the first magnetic component. The positioning and alignment of the transmitting unit and the receiving unit are achieved through magnetic adsorption between the mating component and the first magnetic component.

[0007] Optionally, the magnetic attraction between the mating component and the first magnetic component can be used to move the transmitting unit connected to the first magnetic component, thereby adjusting the relative position of the transmitting unit and the receiving unit.

[0008] Optionally, the wireless charging transmitter further includes a first connecting line, the two ends of which are used to connect the fixing member and the transmitting unit respectively. The receiving module is used to be installed on the body of the robot, and the first connecting line is used to be in a taut state when the robot leaves the transmitting unit.

[0009] Optionally, the transmitting unit includes a first mounting box and a transmitting coil, the transmitting coil being fixed inside the first mounting box, the first magnetic component being fixedly connected to the first mounting box, and the end of the first connecting line away from the fixing component being fixedly connected to the first mounting box.

[0010] Optionally, the control unit is fixed inside the first mounting box.

[0011] Optionally, the control unit is separately and independently disposed from the first mounting box of the transmitting unit; The wireless charging transmitter also includes a second mounting box, and the control unit is fixed inside the second mounting box. The second mounting box is used to fix and connect to the fixing component.

[0012] Optionally, the wireless charging transmitter also includes a second connecting line, which is arranged vertically. The top and bottom ends of the second connecting line are used to connect the fixing member and the transmitting unit respectively to suspend the transmitting unit.

[0013] Optionally, the wireless charging transmitter further includes at least two second connecting lines, which are arranged in parallel and are used to reduce the torsional amplitude of the transmitting unit.

[0014] Optionally, the first magnetic component is a magnet, or the first magnetic component is an electromagnetic chuck that generates electromagnetic attraction when energized.

The receiving unit is electrically connected to the battery pack for wirelessly charging the battery pack.

[0017] The beneficial effects of this invention's wireless charging transmitter, wireless charging system, and robot are: The wireless charging transmitter mainly includes a control unit, a transmitting unit, and a first magnetic component. 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 DC or 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. When the robot needs to charge and moves close to the transmitting unit, the mating component of the receiving module and the first magnetic component attract each other using their magnetism. This causes the transmitting unit connected to the first magnetic component to move towards the receiving module, adjusting the relative position of the transmitting unit and the receiving unit until the receiving unit of the receiving module and the transmitting unit are quickly aligned. The receiving unit can then receive the alternating magnetic field emitted by the transmitting unit and convert it into AC current first, and then into DC current, thereby enabling wireless charging of the robot's battery pack.

[0018] Since the receiving unit achieves quick alignment with the transmitting unit through the adsorption of the mating part and the first magnetic field element, the accuracy requirements for the robot's movement when it needs to be charged can be reduced. Attached Figure Description

[0025] To address the problems existing in the aforementioned related technologies, this utility model provides a wireless charging transmitter, a wireless charging system, and a robot.

[0026] like Figure 1 As shown in the figure, this utility model provides a wireless charging transmitter for wireless connection with a receiving module. The wireless charging transmitter includes: Control unit 110, the input terminal of which is used to connect to a power supply, and the output terminal of which is used to output high-frequency alternating current; The transmitting unit 120 is electrically connected to the output terminal of the control unit 110 and is used to convert the high-frequency alternating current provided by the control unit 110 into an alternating magnetic field. A first magnetic element 130 is connected to the transmitting unit 120. The receiving module 200 includes a receiving unit and a mating component. The receiving unit is used to receive the alternating magnetic field generated by the transmitting unit 120. The mating component is used to magnetically connect with the first magnetic element 130. Through the magnetic attraction between the mating component and the first magnetic element 130, the transmitting unit 120 connected to the first magnetic element 130 is moved to achieve the positioning and alignment of the transmitting unit 120 and the receiving unit.

[0027] Specifically, the receiving module 200 can be installed on the robot's main body 400. The power supply can be a DC power supply or an AC power supply.

[0028] The control unit 110 is electrically connected to the power supply and is used to convert the DC or AC power supplied by the power supply into high-frequency current.

[0029] The wireless charging transmitter 100 also includes a first wire 160 and a second wire 170. The input terminal of the control unit 110 can be electrically connected to the power supply through the first wire 160, and the output terminal of the control unit 110 can be electrically connected to the transmitter unit 120 through the second wire 170.

[0030] The first magnet can be fixedly connected to the launching unit 120, and the two can move synchronously.

[0031] The mating component can be fixedly connected to the receiving unit, and the two can move synchronously.

[0032] The first magnetic component 130 and the mating component can be magnetically connected.

[0033] When the first magnetic component 130 is magnetically connected to the mating component, the positions of the transmitting unit 120 and the receiving unit correspond to achieve coupled charging, thereby appropriately reducing the robot's movement accuracy requirements during charging.

[0034] In this embodiment, the wireless charging transmitter 100 mainly includes a control unit 110, a transmitter 120, and a first magnetic component 130. The input and output terminals of the control unit 110 are electrically connected to the power supply and the transmitter 120, respectively, so that the DC or AC power supplied by the power supply can be converted into high-frequency AC power and transmitted to the transmitter 120. The transmitter 120 can convert the high-frequency AC power output by the control unit 110 into an alternating magnetic field. When the robot needs to be charged and moves close to the wireless charging transmitter, the mating component of the receiver module 200 and the first magnetic component 130 are attracted and connected by their magnetism, so as to drive the transmitter 120 connected to the first magnetic component 130 to move towards the receiver module 200, so as to adjust the relative position of the transmitter 120 and the receiver until the receiver unit of the receiver module 200 and the transmitter 120 are quickly aligned and coupled. The receiver unit can receive the alternating magnetic field emitted by the transmitter 120 and convert it into AC current and then into DC current, thereby realizing the wireless charging operation of the robot's battery pack.

[0035] Since the receiving unit achieves quick alignment with the transmitting unit 120 by adsorption between the mating part and the first magnetic field element, the requirements for the robot's movement accuracy when it needs to be charged can be reduced.

[0036] Optionally, the magnetic attraction between the mating component and the first magnetic component 130 can be used to move the transmitting unit 120 connected to the first magnetic component 130, thereby adjusting the relative position of the transmitting unit 120 and the receiving unit.

[0037] Optionally, combined Figure 1 As shown, the wireless charging transmitter 100 also includes a first connecting line 140, the two ends of which are used to connect the fixing member 300 and the transmitting unit 120 respectively. The receiving module 200 is used to be installed on the main body 400 of the robot. The first connecting line 140 is used to be in a taut state when the robot leaves the transmitting unit 120.

[0038] Specifically, the fastener 300 can be a fixed structure such as a column or wall. The first connecting line 140 can be set horizontally or at a small angle to the horizontal plane.

[0039] The first connecting line 140 may be a flexible connector, such as a chain, a thin steel wire rope, or a rope made of other materials such as nylon.

[0040] In this optional embodiment, the first connecting line 140 can be in a relaxed state before and during the charging phase of the robot's battery pack. 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 component 130 can be smoothly disengaged from the mating component and the receiving unit without the need for manual disengagement of the transmitting unit 120 and the receiving unit, thus saving labor costs.

[0041] Optionally, combined Figure 2 and Figure 3 As shown, the transmitting unit 120 includes a first mounting box 121 and a transmitting coil 122. The transmitting coil 122 is fixed inside the first mounting box 121. The first magnetic component 130 is fixedly connected to the first mounting box 121. The end of the first connecting line 140 away from the fixing component 300 is fixedly connected to the first mounting box 121.

[0042] Specifically, the transmitting coil 122 and the first magnetic element 130 can be installed in the first mounting box 121 in the following manner: for example, the first mounting box 121 is provided with a first mounting part 1211 and a second mounting part 1212. The transmitting coil 122 can be installed at the first mounting part 1211 and the first magnetic element 130 can be installed at the second mounting part 1212.

[0043] The first mounting part 1211 and the second mounting part 1212 may be a groove structure, a through hole structure, etc., provided in the first mounting box 121.

[0044] The first magnetic component 130 can be disposed inside the first mounting box 121 or installed on the outer wall of the first mounting box 121.

[0045] Through holes can be made on the outer edge of the first mounting box 121, such as the bottom edge or corner, and the end of the first connecting line 140 away from the fastener 300 can pass through the through hole and be fixedly connected to the first mounting box 121.

[0046] In this optional embodiment, since the transmitting coil 122 is fixed inside the first mounting box 121, the transmitting coil 122 can be protected by the first mounting box 121. The first magnetic component 130 is fixedly connected to the first mounting box 121, so that when the mating component of the receiving module 200 is magnetically attracted to the first magnetic component 130, it can drive the first mounting box 121 and the transmitting coil 122 disposed in the first mounting box 121 to move, so that the transmitting unit 120 and the receiving unit can be quickly aligned.

[0047] The two ends of the first connecting line 140 can be fixedly connected to the fastener 300 and the first mounting box 121, respectively.

[0048] Optionally, the control unit 110 is fixed inside the first mounting box 121.

[0049] Specifically, the control unit 110 can be fixed in the first mounting box 121 in the following manner, for example, a third mounting part can be provided in the first mounting box 121. Figure 3 (Not shown in the image), the control unit 110 can be embedded in the third mounting section.

[0050] The third mounting section can be a through hole, groove, or other structure.

[0051] In this optional embodiment, the control unit 110 is fixed inside the first mounting box 121. In other words, the control unit 110, the transmitting coil 122, and the first magnetic component 130 can be integrated and installed inside the first mounting box 121. In this case, when the robot approaches the transmitting unit 120, it can also move the transmitting coil 122 and the control unit 110 inside the first control box by relying on the magnetic attraction between the mating component on the robot body 400 and the first magnetic component 130, so as to approach the receiving unit and realize the alignment action between the receiving unit and the transmitting unit 120 before the charging operation.

[0052] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the control unit 110 and the first mounting box 121 of the transmitting unit 120 are set separately and independently; The wireless charging transmitter 100 also includes a second mounting box, and the control unit 110 is fixed inside the second mounting box. The second mounting box is used to fix and connect to the fixing member 300.

[0053] Specifically, the fact that the control unit 110 and the first mounting box 121 of the transmitting unit 120 are set up separately and independently means that there is no mechanical connection between the two. The control unit 110 is only electrically connected to the transmitting coil 122 in the first mounting box 121 of the transmitting unit 120.

[0054] The fastener 300 is used to provide an installation position for the fixed installation of the control unit 110. The fastener 300 can be a column or a wall, etc.

[0055] In this optional embodiment, the control unit 110 is installed inside the second mounting box, which provides safety protection for the control unit 110. The second mounting box can be installed on the fixing member 300 by means of bolts, fasteners, clamps, cable ties, etc., so that the control unit 110 is fixedly installed on the fixing member 300 through the second mounting box.

[0056] Since the control unit 110 and the first mounting box 121 of the transmitting unit 120 are set separately and independently, the weight of each component in the first mounting box 121 of the transmitting unit 120 can be reduced, which helps the magnetic adsorption of the mating parts and the first magnetic parts 130 to quickly move the transmitting unit 120 as a whole. Correspondingly, it helps the receiving unit and the transmitting unit 120 to be quickly aligned. Moreover, it can also avoid the heat concentration of each component in the first mounting box 121, which can extend the service life of the transmitting unit 120.

[0057] Optionally, combined Figure 1 As shown, the wireless charging transmitter 100 also includes a second connecting line 150, which is arranged vertically. The top and bottom ends of the second connecting line 150 are used to connect the fixing member 300 and the transmitter unit 120 respectively, so as to suspend the transmitter unit 120.

[0058] Specifically, the second connecting line 150 is used to suspend the launching unit 120 so that it is in a suspended state. Therefore, the second connecting line 150 can be a flexible connector, such as a chain, wire rope or rope made of other materials such as nylon.

[0059] The second connecting line 150 can be set vertically, which can be understood as the second connecting line 150 and... Figure 1 The Z-axis of the coordinate system is parallel or at a small angle to each other.

[0060] The top end of the second connecting line 150 can be fixedly connected to the top end of the fixing member 300, such as the top end of the column, by means of a connecting plate with holes, and the bottom end of the second connecting line 150 is fixedly connected to the first mounting box 121 of the transmitting unit 120.

[0061] The bottom end of the second connecting line 150 can be fixedly connected to the first mounting box 121 of the transmitting unit 120 in the following ways: For example, at least two through holes spaced apart can be opened on the top of the first mounting box 121. The bottom end of the second connecting line 150 passes through one through hole and then exits through the other through holes, connecting to the portion above the bottom end of the second connecting line 150, thereby achieving a fixed connection between the second connecting line 150 and the first mounting box 121. Alternatively, a bolt fastener can be fixedly connected to the bottom end of the second connecting line 150. A threaded hole can be opened on the top of the first mounting box 121, and the bottom end of the second connecting line 150 can be screwed into the threaded hole using a bolt fastener, also achieving a fixed connection with the first mounting box 121.

[0062] In this optional embodiment, the transmitting unit 120 can be connected to the fixing member 300 via the second connecting line 150 to enable the suspending or lifting operation of the transmitting unit 120. This is equivalent to the first magnetic member 130 disposed on the transmitting unit 120 being able to move the transmitting unit 120 under the magnetic adsorption of the mating member of the receiving module 200, thereby enabling the movable setting of the transmitting unit 120. This facilitates the rapid alignment of the robot's receiving module 200 with the transmitting unit 120 and the charging operation. This embodiment is applicable to robots, such as humanoid robots, where the receiving module 200 has a certain setting height. The suspension or lifting height of the transmitting unit 120 can be matched with the height of the receiving module 200 of the robot, such as the humanoid robot.

[0063] If the wireless charging transmitter 100 does not include the second connecting line 150, the transmitter unit 120 does not need to be suspended and can be laid on the ground. This is applicable to robots, such as quadruped robots (like robot dogs).

[0064] Optionally, combined Figure 1 As shown, the wireless charging transmitter 100 also includes at least two second connecting lines 150, which are arranged in parallel and are used to reduce the torsional amplitude of the transmitter unit 120.

[0065] Specifically, the number of second connecting lines 150 can be multiple, such as... Figure 1 As shown, the number of second connecting lines 150 can be two.

[0066] The parallel directions of at least two second connecting lines 150 can be perpendicular to or at a small angle to the magnetic attraction between the mating parts of the receiving module 200 and the first magnetic element 130 disposed on the transmitting unit 120, thereby driving the transmitting unit 120 to move. The parallel directions of at least two second connecting lines 150 can also be perpendicular to the magnetic attraction between the receiving module 200 and the first magnetic element 130 disposed on the transmitting unit 120, thereby driving the transmitting unit 120 to move. Figure 1 In the coordinate system, the X-axis is parallel or forms a small angle.

[0067] In this optional embodiment, when the robot needs to charge and approaches the transmitting unit 120, the mating part of the receiving module 200 and the first magnetic part 130 disposed on the transmitting unit 120 are magnetically attracted to each other, which will drive the transmitting unit 120 to move towards the robot, so as to shorten the distance between the receiving module 200 and the robot, until the mating part and the first magnetic part 130 are magnetically connected. At this time, the receiving unit and the transmitting unit 120 are aligned, preparing for subsequent wireless charging.

[0068] Since the robot's direction of movement is not necessarily perpendicular to the larger surface of the transmitter 120 during its movement toward the transmitter 120, but may be set at other angles, the attraction between the mating part and the first magnetic part 130 will cause the transmitter 120, which is in a suspended posture, to twist relative to the second connecting line 150 until the receiving unit and the transmitter coil 122 of the transmitter 120 are completely aligned and attached, thereby achieving flexibility in charging the robot.

[0069] Since at least two second connecting lines 150 are arranged in parallel and spaced apart, and together suspend the transmitting unit 120 and the first magnetic element 130, the torsion amplitude of the transmitting unit 120 can be reduced by the at least two second connecting lines 150. For example, the transmitting unit 120 can be prevented from reversing more than 180 degrees and failing to align with the receiving module 200, thereby improving the alignment reliability between the receiving module 200 and the transmitting unit 120.

[0070] Optionally, the first magnetic component 130 is a magnet, or the first magnetic component 130 is an electromagnetic chuck that generates electromagnetic attraction when energized.

[0071] Specifically, if the first magnetic component 130 is a magnet, it can be named the first magnet, and the mating component can be the second magnet. The opposing surfaces of the first magnet and the second magnet have opposite magnetic properties to ensure that the first magnetic component 130 and the mating component can be magnetically attracted and connected. In this embodiment, the mating component can also be a metal with magnetic permeability, such as an iron block structure.

[0072] If the first magnetic component 130 is an electromagnetic chuck that generates electromagnetic attraction when energized, then the mating component can be a blocky structure of metal with magnetic properties, such as iron. An electromagnetic chuck is a specially designed device that uses the principle of electromagnetism to attract and fix magnetically conductive workpieces (such as steel). Essentially, it is an electromagnet of a specific shape and purpose. The electromagnetic chuck includes a housing and a coil and iron core disposed inside the housing. At least one surface of the housing is typically a flat steel platform. When the coil is energized, the magnetic lines of force form a closed loop through the platform and the workpiece, thereby generating a strong attraction force, thus enabling magnetic attraction of the mating component. Electromagnetic chucks are existing technology.

[0073] This utility model provides a wireless charging system, including a wireless charging transmitter 100 as described in the above embodiment, and a fixing member 300, wherein the wireless charging transmitter 100 is connected to the fixing member 300.

[0074] Specifically, the fastener 300 can be a column or a wall.

[0075] If the fixing member 300 is a column, the control unit 110 can be fixedly installed on the side wall of the column. The two ends of the first connecting line 140 are fixedly connected to the portion between the two ends of the column and the first mounting box 121 of the transmitting unit 120, respectively. The top and bottom ends of the second connecting line 150 are fixedly connected to the top of the column and the first mounting box 121 of the transmitting unit 120, respectively. (See...) Figure 1 As shown.

[0076] The advantages of the wireless charging system in this embodiment over the prior art are the same as those of the wireless charging transmitter 100 described above, and will not be repeated here.

[0077] This utility model provides a robot including a main body 400, a receiving module 200 and a battery pack disposed on the main body 400. The receiving unit of the receiving module 200 is wirelessly connected to the transmitting unit 120 of the wireless charging transmitter 100 as described in the above embodiment. The receiving unit is electrically connected to the battery pack for wirelessly charging the battery pack.

[0078] Specifically, the wireless charging transmitter 100 charges the robot's battery pack as follows: The control unit 110 receives single-phase / three-phase AC power from the power source, rectifies the AC power into DC power, and then inverts the DC power into high-frequency AC power; the transmitting coil 122 converts the AC power into an alternating magnetic field; the receiving unit has a receiving coil coupled to the transmitting coil 122, and the receiving unit receives the alternating magnetic field through the receiving coil, converts it into AC current first, and then into DC current, thereby charging the battery pack.

[0079] The control unit 110 may employ a control circuit or device that can convert DC or AC power supplied by the power source into DC power first, and then invert the DC power into high-frequency AC power. The receiving unit may employ a receiving unit device that can convert the alternating magnetic field provided by the transmitting unit 120 into AC current first, and then into DC current.

[0080] The advantages of the robot in this embodiment over the prior art are the same as those of the wireless charging transmitter 100 described above, and will not be repeated here.

[0081] Although the present invention has been disclosed above, its protection scope 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 protection scope of the present invention.
