[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a wireless charging device that can be applied to self-moving devices. These self-moving devices can be yard robots, such as lawnmowers, snowplows, sprayers, seeders, etc.

[0025] In other embodiments, the self-moving device may also be a robot vacuum cleaner, a pool cleaning robot, or other similar devices.

[0026] In some embodiments, the wireless charging device may include a support plate 100, a wireless charging assembly 200, and a guide assembly 300. The support plate 100 includes a first side 101 and a second side 102 disposed opposite to each other. The wireless charging assembly 200 is floatably connected to the first side 101 of the support plate 100 along a first direction M. The guide assembly 300 is connected to the side of the wireless charging assembly 200 facing the support plate 100, and the guide assembly 300 is slidably disposed through the support plate 100 along the first direction M, and is telescopically disposed relative to the second side 102 of the support plate 100. In an embodiment, the guide assembly 300 may be configured to retract relative to the second side 102 under the action of a driving device, thereby driving the wireless charging assembly 200 to move away from the support plate 100. The driving device may be integrated into the main structure of the self-moving device.

[0027] In this embodiment, the support plate 100 can be fixedly connected to the main structure of the self-moving device, and the first side 101 of the support plate 100 can face the ground. Additionally, the wireless charging component 200 can be electrically connected to the power source in the main structure. When the self-moving device needs charging, it can enter the charging base station. The charging structure in the charging base station, connected to the wireless charging device, can be located below the wireless charging device. The guiding component 300 can be retracted relative to the second side 102 of the support plate 100 by the driving device in the main structure, and the guiding component 300 can move the wireless charging component 200 away from the support plate 100. This allows the wireless charging component 200 to move towards the charging structure in the charging base station and form a reliable connection, so that the power source in the main structure can be charged through the charging structure and the wireless charging component 200.

[0028] The wireless charging device provided in this application enables the lifting and docking of the wireless charging component 200. The guide component 300 guides the lifting and lowering of the wireless charging component 200, thereby ensuring accurate alignment and connection between the wireless charging component 200 and the charging structure in the charging base station. This means the wireless charging component 200 can be completely fitted to the charging structure, avoiding any misalignment. Furthermore, under the action of a driving device within the main structure, the wireless charging component 200 achieves reliable docking with the charging structure in the charging base station. The driving device applies a certain downward pressure to the wireless charging component 200, reducing the possibility of arbitrary separation between the wireless charging component 200 and the charging structure in the charging base station, ensuring smooth wireless charging and high charging efficiency.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, the wireless charging assembly 200 may include a housing assembly 210 and a circuit board 220. The housing assembly 210 includes a first housing 211 and a second housing 212. The first housing 211 and the second housing 212 may be disposed opposite each other along a first direction M, and the first housing 211 and the second housing 212 cooperate to form an accommodating cavity 213. The second housing 212 may be located on the side of the first housing 211 opposite to the support plate 100. In some embodiments, the first housing 211 and the second housing 212 may be fixedly connected by bolts or snap-fit ​​connections.

[0030] In some embodiments, the circuit board 220 may be disposed in the accommodating cavity 213 and fixedly disposed relative to the housing assembly 210. A power module and a secondary coil may be integrated on the circuit board 220. The secondary coil may be located on the side of the circuit board 220 facing the second housing 212, i.e., on the side of the circuit board 220 facing away from the support plate 100. When the wireless charging device is connected to the charging base station, the secondary coil may face the charging structure (i.e., the primary coil) in the charging base station, forming a wireless charging connection.

[0031] In some embodiments, the housing assembly 210 further includes a heat sink 214, which may be plate-shaped. The heat sink 214 may be embedded in the first housing 211 and exposed on both the side of the first housing 211 facing the receiving cavity 213 and the side facing away from the receiving cavity 213. The circuit board 220 may be attached to the side of the heat sink 214 facing the receiving cavity 213. Thus, the heat generated by the circuit board 220 during operation can be dissipated to the outside through the heat sink 214, improving the heat dissipation efficiency of the circuit board 220. In some embodiments, the circuit board 220 may be fixedly connected to the heat sink 214 by means of screw connection or snap-fit, thereby achieving relative fixation between the circuit board 220 and the housing assembly 210.

[0032] In some embodiments, the wireless charging assembly 200 further includes an adapter 420. In some embodiments, the adapter 420 may be a gland connector. The adapter 420 may pass through the first housing 211 and be exposed on both the side of the first housing 211 facing the receiving cavity 213 and the side facing away from the receiving cavity 213. The end of the adapter 420 facing the receiving cavity 213 may be electrically connected to the circuit board 220, and the end of the adapter 420 facing away from the receiving cavity 213 may be used to electrically connect to the main structure to achieve electrical connection between the wireless charging assembly 200 and the main structure.

[0033] like Figures 1 to 3 As shown, in some embodiments, the support plate 100 may be provided with a clearance hole 130, which may be opposite to the adapter 420, and can provide clearance for the adapter 420 to avoid interference with the floating of the wireless charging component 200.

[0034] like Figures 1 to 4 As shown, in some embodiments, the guide assembly 300 may include a first guide member 310 and at least one second guide member 320. The support plate 100 may have a first guide hole 110 and at least one second guide hole 120.

[0035] In some embodiments, the first guide member 310 may include an integral guide portion 311 and a limiting portion 312. The guide portion 311 may have a cubic columnar structure, and one end of the guide portion 311 may be fixedly connected to the side of the heat sink 214 away from the receiving cavity 213 by means of welding, screw connection or snap-fit. The other end of the guide portion 311 may slide through the first guide hole 110 along the first direction M and be telescopically disposed relative to the second side 102 of the support plate 100. In addition, the shape of the first guide hole 110 may match the shape of the guide portion 311, and the guide portion 311 may slide against the inner wall of the first guide hole 110.

[0036] In some embodiments, the limiting portion 312 may be connected to the periphery of the guide portion 311 near the end of the wireless charging assembly 200. The limiting portion 312 may also be located on the side of the support plate 100 facing the wireless charging assembly 200. In this embodiment, the limiting portion 312 may be configured to restrict the travel of the wireless charging assembly 200 when it moves towards the support plate 100, thus preventing the wireless charging assembly 200 from contacting the support plate 100.

[0037] In some embodiments, the outer peripheral side of the limiting portion 312 opposite to the guide portion 311 may be a non-circular structure. The outer diameter of the limiting portion 312 may be larger than the inner diameter of the first guide hole 110. The outer diameter of the limiting portion 312 may refer to the diameter of its circumscribed circle, and the inner diameter of the first guide hole 110 may refer to the diameter of its inscribed circle.

[0038] In other embodiments, the guide portion 311 may be cylindrical, and the first guide hole 110 may be configured as a matching circular hole. The inner diameter of the first guide hole 110 may refer to the inner diameter of the first guide hole 110 itself.

[0039] In other embodiments, the outer periphery of the limiting portion 312 on the side opposite to the guide portion 311 may be circular. The outer diameter of the limiting portion 312 may refer to the outer diameter of the limiting portion 312 itself.

[0040] In some embodiments, the first guide member 310 may also be made of a heat dissipation material such as metal. The limiting portion 312 may include a plurality of fins 3121, which may be symmetrically distributed on opposite sides of the guide portion 311. Thus, the heat dissipation area can be increased by the limiting portion 312, and the heat dissipation efficiency of the circuit board 220 can be further improved.

[0041] In some embodiments, the end of the guide portion 311 that protrudes relative to the second side 102 of the support plate 100 may be opposite to the driving device in the main structure, and the driving device may drive the guide portion 311 to retract relative to the second side 102. When the driving device is activated, the output end of the driving device may gradually press against the guide portion 311 and push the guide portion 311 to move along the first direction M toward the direction close to the wireless charging component 200, thereby causing the wireless charging component 200 to move downward.

[0042] In other embodiments, the output end of the drive device may be connected to the end of the guide portion 311 that protrudes relative to the second side 102. Thus, the drive device can drive the guide portion 311 to extend and retract relative to the second side 102 of the support plate 100, thereby driving the guide portion 311 to move up and down, and in turn, the guide portion 311 drives the wireless charging component 200 to float up and down.

[0043] like Figures 1 to 4 As shown, in some embodiments, the guide assembly 300 may include two, three, or five or more second guide members 320. The multiple second guide members 320 may be arranged around the periphery of the first guide member 310, and the second guide members 320 may be fixedly connected to the side of the heat sink 214 facing the support plate 100 by means of welding, snap-fitting, bonding, or screwing. The support plate 100 may have a number of second guide holes 120 equal to the number of second guide members 320. The ends of the multiple second guide members 320 away from the heat sink 214 can slide through the multiple second guide holes 120 one by one.

[0044] In other embodiments, a plurality of second guide members 320 may also be disposed on the same side or opposite sides of the first guide member 310.

[0045] In other embodiments, the guide assembly 300 may also include a second guide member 320. A second guide hole 120 may be provided on the support plate 100.

[0046] In some embodiments, the wireless charging device further includes guide sleeves 410 extending along a first direction M, the number of guide sleeves 410 being equal to the number of second guide holes 120. Multiple guide sleeves 410 are inserted one-to-one into multiple second guide holes 120 and can be fixed to the support plate 100 by snap rings. A second guide member 320 is slidably inserted into a guide sleeve 410 corresponding to a second guide hole 120. In this embodiment, the extension length of the guide sleeve 410 along the first direction M is greater than the thickness of the support plate 100 along the first direction M. This allows the guide sleeve 410 and the second guide member 320 to have a larger guiding area, improving the stability of the second guide member 320 during sliding relative to the support plate 100, and further improving the stability of the wireless charging assembly 200 during floating, ensuring accurate docking between the wireless charging assembly 200 and the charging base station.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the wireless charging device further includes an elastic reset member 510, which can be connected between the support plate 100 and the wireless charging assembly 200. The elastic reset member 510 can be configured to drive the wireless charging assembly 200 to move and reset towards the support plate 100. During use, when charging is complete, the driving device can release the pressure on the first guide member 310, and the wireless charging assembly 200 can move and reset towards the support plate 100 under the action of the elastic reset member 510. In the embodiments, when the guide member 300 is not pressed by the driving device, the elastic reset member 510 can be in a naturally extended state or a stretched state.

[0048] In some embodiments, the resilient reset member 510 may be an elastic sleeve, and the resilient reset member 510 may be disposed around the periphery of the wireless charging assembly 200. Thus, the resilient reset member 510 can provide protection for the structure between the wireless charging assembly 200 and the support plate 100, for example, reducing the possibility of debris adhering to the surface of the heat sink 214, ensuring the heat dissipation efficiency of the heat sink 214, and thereby ensuring the normal operation of the circuit board 220.

[0049] In some embodiments, both ends of the elastic reset member 510 are provided with connecting flanges 511. One end of the connecting flange 511 of the elastic reset member 510 can be fitted against the side of the support plate 100 facing the wireless charging assembly 200. A first pressure ring 521 is fitted against the side of the connecting flange 511 facing away from the support plate 100. The first pressure ring 521 can be fixedly connected to the support plate 100 by bolts or other means, and can press and fix the connecting flange 511 of the elastic reset member 510 facing the support plate 100. Thus, a fixed connection between the elastic reset member 510 and the support plate 100 can be achieved.

[0050] In some embodiments, the periphery of the second housing 212 may be provided with a connecting flange 2121 protruding relative to the periphery of the first housing 211. A connecting flange 511 at the other end of the elastic reset member 510 may be fitted to the side of the connecting flange 2121 facing the support plate 100. A second pressure ring 522 is fitted to the side of the connecting flange 511 facing away from the connecting flange 2121. The second pressure ring 522 can be fixedly connected to the connecting flange 2121 by means of bolts or the like, and can clamp and fix the connecting flange 511 at the end of the elastic reset member 510 facing the connecting flange 2121. Thus, a fixed connection between the elastic reset member 510 and the wireless charging assembly 200 can be achieved.

[0051] In other embodiments, the elastic reset member 510 may also be a tension spring, elastic rope, or elastic column.

[0052] In this embodiment, the wireless charging component 200 is floatingly connected to the support plate 100 via an elastic reset member 510. Under the action of the elastic reset member 510, the wireless charging component 200 is allowed to have a certain height adjustment range in the first direction M, so as to adapt to the position of the charging base station. At the same time, when the wireless charging component 200 is connected to the charging base station, the elastic reset member 510 can provide a certain buffering effect to avoid rigid collisions between the wireless charging component 200 and other structures, thus preventing damage.

[0053] In this embodiment, the first housing 211 and the second housing 212, as well as the second housing 212 and the elastic reset member 510, in the wireless charging device can be detachably connected by bolts. This facilitates subsequent inspection and maintenance of the wireless charging device and allows for easy disassembly and replacement.

[0054] The embodiment also provides a self-moving device, which may include a main structure and the wireless charging device provided in the embodiment. The support plate 100 of the wireless charging device can be fixedly connected to the main structure by means of bolts or other methods.
