[0036] As Figure 1 and Figure 2 shown, in an embodiment of the present utility model, the wireless charging device 6 includes:

[0037] A wireless charging board 1;

[0038] A circuit box 2, disposed at a first position at the bottom of the wireless charging board 1, forming a first enclosed space with the wireless charging board 1, and the first enclosed space is used to accommodate the charging circuit in the wireless charging device 6;

[0039] A coil box 3, including a positioning coil box 301 and a transmitting coil box 302, disposed at a second position at the bottom of the wireless charging board 1, respectively forming a second enclosed space with the wireless charging board, and the second enclosed space is used to accommodate the positioning coil (not shown in the figure) and the transmitting coil 3015 in the wireless charging device 6.

[0040] In the above embodiments, the wireless charging board 1 can be the main structure of the wireless charging device 6. Its upper end surface can be used to park the automatic robot that needs to be wirelessly charged. A structure for accommodating various components is provided on its bottom surface. The shape of the charging board is not limited, and the charging board surface can be set at a certain slope relative to the ground; the circuit box 2 can enclose with the wireless charging board 1 to form a first closed space for accommodating the charging circuit. In this space, the chips and circuits in the charging circuit can be stored. The material of the circuit box 2 can be selected as a metal material with a certain strength to resist collisions or frictions and other specific actions. The first position where the circuit box 2 is set can be any position at the bottom of the wireless charging board 1. In order to be connected to the external power supply device, the circuit box 2 can be set at the head position of the wireless charging board 1; the coil box can include a positioning coil box 301 and a transmitting coil box 302. The two coil boxes 3 can be arranged at intervals. Their winding methods are separately set in their respective coil boxes 3. The coil box 3 can enclose with the wireless charging board 1 to form a second closed space for accommodating the coils. The second position where the coil box 3 is set can be any position at the bottom of the wireless charging board 1. Its setting position can be selected in the middle area of the wireless charging board 1 to meet the requirement that the automatic robot can conveniently achieve the wireless charging function on the wireless charging board 1;

[0041] Among them, the circuit box 2 for accommodating the charging circuit in the wireless charging device 6 in this application is integrated with the wireless charging board 1, which does not require the user to install, and at the same time can reduce the overall volume of the wireless charging device 6. The positioning coil (not shown in the figure) is accommodated in the positioning coil box 301, and the transmitting coil 3015 is accommodated in the transmitting coil box 302. The two coils are arranged without interference. When one of them has a problem, the coil of the faulty coil box 3 can be processed separately, which is convenient for the user to maintain.

[0042] As Figure 1 and Figure 2 shown, in one embodiment, the circuit box 2 is provided with an opening (not shown in the figure), and one side of the opening (not shown in the figure) forms the first closed space with the wireless charging board 1.

[0043] In the above embodiments, one side of the circuit box 2 can be provided with an opening (not shown in the figure), and the opening (not shown in the figure) can facilitate the user to store the charging circuit. Among them, after the charging circuit is placed, the circuit box 2 is fixed on the wireless charging board 1 through the installation position set in the circuit box 2. In this way, the circuit box 2 can form the first closed space with the wire charging board; in addition, multiple adapted installation positions for placing the charging circuit can be divided inside the circuit box 2. In this way, the internal position of the circuit box 2 can be divided.

[0044] As Figure 1 shown, in one embodiment, a wire passing hole 202 is opened on one side of the circuit box 2, and the charging circuit is connected to the external power supply device through the wire passing hole 202.

[0045] In the above embodiments, the electric energy required in the wireless charging device 6 needs to be provided by an external power supply device. A wire passing hole 202 adapted to the wires in the charging circuit is formed on one side of the circuit box 2. In this way, the wireless charging device 6 can stably receive the electric energy provided by the external power supply device through the wires passing through the wire passing hole 202.

[0046] As Figure 1 shown, in one embodiment, a groove 203 arranged in one direction is provided on one side of the circuit box 2 opposite to the opening (not shown in the figure).

[0047] In the above embodiments, on one side of the circuit box 2 opposite to the opening (not shown in the figure), that is, on the side of the circuit box 2 close to the ground, a plurality of grooves 203 in the same direction are provided. In this way, after the wireless charging device 6 is placed on the ground, the grooves 203 can increase the friction force and can also guide some objects, such as water, through the grooves 203.

[0048] As Figure 1 shown, in one embodiment, the positioning coil box 301 includes a first positioning coil box 3013 and a second positioning coil box 3014, and the first positioning coil box 3013, the second positioning coil box 3014 and the transmitting coil box 302 are arranged at intervals.

[0049] In the above embodiments, there can be two positioning coil boxes 301. Both of the two positioning coil boxes 301 are arranged at intervals from the transmitting coil box 302. The two positioning coil boxes 301 can be connected by wires. Both of the two positioning coil boxes 301 can realize the positioning function of the robot. The positioning coil box 301 and the transmitting coil box 302 are arranged at intervals, which is equivalent to the positioning coil (not shown in the figure) and the transmitting coil 3015 being arranged at intervals. In this way, when the automatic robot moves to the wireless charging device 6 for wireless charging, once the automatic robot senses the positioning coil (not shown in the figure), the function of transmitting energy to the automatic robot can be realized through the transmitting coil 3015;

[0050] In addition, the coil in the first positioning coil box 3013 above is a position detection coil, and the coil in the second positioning coil box 3014 is a coil for adjusting the pose of the robot. That is, after the robot adjusts its pose at the position where the second positioning coil box 3014 is located, it starts to move to the position where the first positioning coil box 3013 is located and then stops moving and completes the wireless charging process;

[0051] In addition, a mounting plate 3017 can be arranged above the second coil box 3014. After the second coil box 3014 is installed on the wireless charging board, the mounting plate 3017 is stacked on the second coil box 3014. In this way, it can play a role in fixing the second coil box 3014 on the wireless charging board and also prevent the positioning coil in the second coil box 3014 from being damaged.

[0052] As Figure 3 and Figure 4 shown, in one embodiment, a lead slot 3011 for leading wires and a wire slot 3012 for accommodating the positioning coil are arranged inside the positioning coil box 301.

[0053] In the above embodiment, the coil accommodated in the positioning coil box 301 is formed by winding. After the positioning coil (not shown in the figure) is placed in the wire slot 3012, it can interact with the device outside the positioning coil box 301 through the lead slot 3011. In this way, it can ensure that the positioning coil (not shown in the figure) emits a positioning magnetic field outward in the specified positioning coil box 301.

[0054] As Figure 4 and Figure 5 shown, in one embodiment, the wireless charging device 6 further includes a support member 4. The bottom of the support member 4 is stacked on the positioning coil box 301. A support column 401 for strengthening the support is also arranged inside the support member 4, and a support plate 402 connected to the surface of the support member 4 is arranged on the surface of the support column 401.

[0055] In the above embodiment, the support member 4 can be a cylindrical structure, which protrudes from the wireless transmission board. At the same time, multiple cylindrical structures can be arranged for the support member 4. For example, two cylindrical structures are arranged for the whole support member 4. When there are multiple cylindrical structures for the support member 4, a connecting plate can be arranged to connect the multiple cylindrical structures. The connecting plate can be stacked on the positioning coil (not shown in the figure) in the wire slot 3012. In addition, a support column 401 for strengthening the support can also be arranged at the center inside the support member 4, and a support plate 402 connected to the surface of the support member 4 is arranged on the surface of the support column 401. For example, four support plates 402 are arranged on the surface of the support column 401. In this way, the support member 4 designed above can not only cover and fix the positioning coil box 301, but also support the whole wireless charging device 6.

[0056] As Figure 6 shown, in one embodiment, a mounting member 3021 for fixing the transmitting coil box 302 to the wireless charging board 1 is arranged on the outer periphery of the transmitting coil box 302, and a wiring slot 3022 for accommodating the transmitting coil is formed by surrounding the outer periphery of the transmitting coil box 302.

[0057] In the above embodiments, a plurality of mounting members 3021 for fixing the transmitting coil box 302 are provided on the outer peripheral side of the transmitting coil box 302. The mounting members 3021 can adopt a threaded structure or a snap structure. A wiring groove 3022 for placing the transmitting coil can be formed on the outer peripheral side of the transmitting coil box 302. In this way, after the transmitting coil is placed in the wiring groove 3022, it can be stably stored, and the transmitting coil will not easily shake or shift.

[0058] As Figure 6 shown, in one embodiment, the wireless charging board 1 further includes a grille 503 bottom plate 5. A plurality of horizontal plates 501 arranged at intervals in a first direction and a plurality of vertical plates 502 arranged at intervals in a second direction are provided on a side of the grille 503 bottom plate 5 close to the ground. The horizontal plates 501 and the vertical plates 502 are arranged in a cross pattern to form a grille 503 on the grille bottom plate 5.

[0059] In the above embodiments, the second direction can be perpendicular to the first direction. Among them, the first direction is the left - right direction, and the second direction is the up - down direction. The grille bottom plate 5 includes horizontal plates 501 and vertical plates 502 in two different directions. The horizontal plates 501 and the vertical plates 502 are arranged in a cross pattern to form a grille 503 on the grille bottom plate 5. The connection between the horizontal plates 501 and the vertical plates 502 has high firmness. Therefore, the grille 503 has the advantages of good structural stability, high fatigue resistance, and is also convenient for installation and easy to maintain. At the same time, the middle of the grille bottom plate 5 is in a hollow shape, which is beneficial for ventilation and heat dissipation, and can effectively extend the service life of the wireless charging device 6.

[0060] As Figure 6 shown, in one embodiment, the grille bottom plate 5 is stacked on the transmitting coil box 3, and the area of the grille bottom plate 5 covers the transmitting coil box 302.

[0061] In the above embodiments, the grille bottom plate 5 is stacked on the transmitting coil box 302, and at the same time, the area of the grille bottom plate 5 covers the transmitting coil box 302. In this way, the transmitting coil box 302 can be firmly fixed to the wireless charging device 6 and will not easily shift.

[0062] In one embodiment, the circuit box 2 can be subjected to potting treatment. Potting treatment refers to pouring polyurethane potting glue, silicone potting glue, or epoxy resin potting glue into a device containing electronic components and circuits by equipment or manually, and curing it into a thermosetting polymer insulating material with excellent performance at normal temperature or under heating conditions, so as to achieve the purposes of bonding, sealing, potting, and coating protection. Potting treatment can strengthen the integrity of electronic devices, improve the resistance to external impacts and vibrations, and can also improve the insulation between internal components and circuits, avoid the direct exposure of components and circuits, further ensure the waterproof effect, and extend the service life of the wireless charging device 6.

[0063] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
