Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings... Figure 1 ...to the attached drawings... Figure 7 The technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0033] It should be noted that if there are directions involved in the embodiments of the present utility model, they shall be subject to those shown in the attached drawings. If a specific posture changes, the directional indication shall also change accordingly.

[0034] The wireless charging mat has a variety of application scenarios and is often used in multiple places such as homes, offices, commercial places, or public areas. For example, when people are resting and watching TV or interacting with their families in the living room at home, they can casually place their mobile phones on the mat for charging without having to search for charging plugs everywhere, thus keeping the indoor environment clean and beautiful.

[0035] Existing wireless charging mats usually have a charging area on the mat surface for external devices to charge and dock, and then a charging module is set inside the mat to maintain the wireless charging mat to continuously supply power to the external device. However, when the external device needs to be charged, it is necessary to manually move the external device to the charging area of the wireless charging mat to achieve charging. This charging method is very cumbersome and inconvenient.

[0036] In view of this, the inventor provides a technical solution aimed at solving the problem that the device needs to be moved to the charging area of the wireless charging mat to achieve charging. This technical solution can be used to charge a sweeping robot, a service robot or some other anthropomorphic robot devices.

[0037] In this embodiment, the external device is an anthropomorphic robot, such as Figure 1 As shown, a wireless charging mat device of this technical solution includes a mat 1 and a wireless charging body 2. The wireless charging body 2 is arranged at the mat 1. The wireless charging body 2 has a control circuit board 22 and a wireless charging module 23 electrically connected to the control circuit board 22. The control circuit board 22 is electrically connected to a wireless locator 24, and the wireless locator 24 is used to transmit a guiding signal outward.

[0038] During use, the anthropomorphic robot is equipped with an infrared signal receiver for receiving the guiding signal transmitted outward by the wireless locator 24. After the processing and analysis module in the anthropomorphic robot receives the guiding signal information transmitted outward by the wireless locator 24 through its infrared signal receiver, the driving mechanism in the anthropomorphic robot drives the robot to the wireless charging mat device for charging. During this process, the wireless locator 24 realizes the precise navigation of the anthropomorphic robot to the wireless charging area to achieve precise charging of the anthropomorphic robot. Thus, the technical problem that the robot needs to rely on manual assistance to move to the wireless charging area for charging during charging and is inconvenient to use is solved.

[0039] It should be noted that in this embodiment, the wireless locator 24 is an infrared signal transmitter for transmitting a guiding signal outward. It should be understood that an infrared signal receiver is correspondingly provided on the anthropomorphic robot for receiving the transmitted guiding signal. Usually, the wireless locator 24 is always in a state of transmitting infrared signals outward. When the anthropomorphic robot needs to be charged, its infrared signal receiver searches for and obtains the transmission information of the infrared signal, and generates data to be given to the data analysis module in the anthropomorphic robot to analyze the position information of the wireless charging mat device. Thus, the anthropomorphic robot can accurately reach the charging area for charging. And, as Figure 2As shown, the charging area of the wireless charging floor mat device is that charging contacts C are arranged on the upper surface B of the wireless charging body 2, and charging contacts are also arranged at the bottom of the anthropomorphic robot corresponding to the charging contacts C. When the two charging contacts are accurately docked, the anthropomorphic robot can achieve effective charging.

[0040] In this embodiment, the wireless locator 24 is arranged inside the wireless charging body 2. In some other specific usage scenarios, the wireless charging body 2 includes shapes such as a square, a circle, or a rhombus. There are multiple wireless locators 24. For example, if the wireless charging body 2 is square, the wireless locators 24 can be arranged in an array around the inside of the wireless charging body 2. It should be understood that the more the number of the wireless locators 24 arranged, the stronger the guiding signal emitted outward, and it is more suitable for use in scenarios with a large space. Of course, the number and arrangement position of the wireless locators 24 are determined according to the actual usage scenario, not limited to the examples described above.

[0041] In some other usage scenarios, the positioning and navigation methods between the wireless charging floor mat device and the anthropomorphic robot also include Bluetooth positioning and Wi-Fi positioning and other modes.

[0042] Of course, preferably, the wireless locator 24 in this embodiment continuously emits infrared waves through an infrared emission device to achieve the navigation and positioning of the anthropomorphic robot.

[0043] Therefore, in order for the wireless locator 24 to work properly, the wireless locator 24 needs to be electrically connected to the control circuit board 22. The control circuit board 22 is also connected to a wireless charging module 23. The wireless charging module 23 is a coil, and this coil is connected to the control circuit board 22 to generate an electromagnetic signal. The anthropomorphic robot end cooperating therewith also has a coil to receive this electromagnetic signal to generate current, so as to realize that the wireless charging floor mat device can charge the anthropomorphic robot.

[0044] In addition, the charging methods of this wireless charging floor mat device also include magnetic field resonance, radio waves, and electric field coupling and other methods, which all belong to the prior art and will not be elaborated one by one here.

[0045] Further, as Figure 3 and Figure 4 shown, the wireless charging body 2 further includes an automatic adjustment unit 221. The automatic adjustment unit 221 is arranged in the control circuit board 22, and the automatic adjustment unit 221 automatically adjusts the charging power and voltage to achieve intelligent fast charging.

[0046] In use, the automatic adjustment unit 221 can monitor and obtain the power data of the anthropomorphic robot and then adjust the charging power and voltage to generate a charging data information. After receiving the charging data information, the control circuit board 22 controls the wireless charging module 23 to output a current signal matching the charging data information.

[0047] In this embodiment, the automatic adjustment unit 221 can be a chip in which the program of the automatic adjustment circuit is written. After being soldered on the control circuit board 22, the chip can interact with the control circuit board 22 for information.

[0048] In another usage scenario, the automatic adjustment unit 221 can also be a separate processing module, which is electrically connected to the control circuit board 22 and the wireless charging module 23 to change the current signal between the control circuit board 22 and the wireless charging module 23.

[0049] Further, as Figure 5 shown, the wireless charging body 2 includes a wire 25, which is electrically connected to the control circuit board 22 to supply power to the control circuit board 22; the wire 25 passes through the floor mat 1 and extends outward from the bottom of the floor mat 1.

[0050] It should be understood that in this embodiment, the floor mat 1 includes a soft or hard material, such as a carpet or a seat cushion used at home. It should be noted that the floor mat adopted is a carpet. Since the carpet usually has a certain elasticity, it makes the wire 25 placed therein not protrude from the surface of the floor mat, and the wire 25 is placed under the floor mat, which overcomes the problem that the wire arrangement on the surface of the floor mat 2 in the prior art is likely to trip up the anthropomorphic robot moving to the charging area.

[0051] For the anthropomorphic robot to move more smoothly to the floor mat, further, Figure 5 and Figure 6 shown, the floor mat 1 has an open receiving space 11 formed by being recessed inward from the upper surface A of the floor mat 1; the wireless charging body 2 is located in the receiving space 11 and is assembled and connected to the floor mat 1.

[0052] It should be understood that the shape of the accommodation space 11 matches the shape of the wireless charging body 2. That is, when the shape of the wireless charging body 2 is square, the cross-section of the corresponding accommodation space 11 is square. The cross-sectional area of the accommodation space 11 is greater than or equal to the cross-sectional area of the wireless charging body 2. Such a design is to enable the wireless charging body 2 to be completely placed in the accommodation space 11 to save placement space. Preferably, the wireless charging body 2 can cover the opening of the accommodation space 11 in the lateral direction. That is, when the wireless charging body 2 is assembled in the accommodation space 11, the end of the wireless charging body 2 is in contact with the inner side wall of the accommodation space 11, that is, there is no gap at the joint between them, to prevent the accumulation of dust and difficult cleaning.

[0053] Further, the upper surface of the wireless charging body 2 is flush with the upper surface A of the floor mat 1. It should be understood that with such a design, when the upper surface of the wireless charging body 2 is flush with the upper surface A of the floor mat 1, the anthropomorphic robot moving to this charging area will not be tripped because the wireless charging body 2 is higher than the upper surface A of the floor mat 1, and it will not cause the bottom of the anthropomorphic robot to be unable to smoothly dock with the charging contact C accurately due to the wireless charging body 2 being higher than the upper surface A of the floor mat 1, resulting in inability to charge.

[0054] Further, as Figure 6 shown, the wireless charging body 2 and the floor mat 1 are detachably assembled and connected. Specifically, the detachable assembly connection between the wireless charging body 2 and the floor mat 1 can be achieved by using Velcro. It should be understood that the Velcro usually has a male and a female surface, and the two objects are detachably assembled and connected by hooking the male and female surfaces together.

[0055] Specifically, a Velcro male surface is adhered to the side of the wireless charging body 2 facing the floor mat 1, and a Velcro female surface is also adhered to the side of the accommodation space 11 in the floor mat 1 facing the wireless charging body 2. When the wireless charging body 2 is assembled in the accommodation space 11, the Velcro male surface and the Velcro female surface are hooked together, thereby realizing the detachable assembly connection between the wireless charging body 2 and the floor mat 1.

[0056] In addition, Velcro can also be provided on the side wall of the wireless charging body 2. For example, the Velcro male surface is adhered to the side wall of the wireless charging body 2, and the side wall of the accommodation space 11 corresponding to the position of this Velcro male surface is provided with a Velcro female surface, and then the Velcro male surface and the Velcro female surface are hooked together, thereby realizing the detachable assembly connection between the wireless charging body 2 and the floor mat 1. Of course, the installation position of this Velcro can be adjusted according to actual needs, not limited to the two methods listed above.

[0057] In some other embodiments, the detachable assembly connection between the wireless charging body 2 and the floor mat 1 can also be achieved by providing a magnetic sheet on the side of the wireless charging body 2 facing the floor mat 1, and providing another magnetic sheet on the side of the accommodation space 11 facing the wireless charging body 2. According to the principle of mutual attraction between magnetic objects, the wireless charging body 2 and the floor mat 1 are detachably assembled and connected.

[0058] Of course, there are many ways to detachably assemble and connect the wireless charging body 2 and the floor mat 1, not limited to the above two. As long as the detachable assembly connection between the wireless charging body 2 and the floor mat 1 can be achieved.

[0059] In addition, the design of the detachable assembly connection between the wireless charging body 2 and the floor mat 1 is helpful for replacing and maintaining the wireless charging body 2. Especially when the floor mat 1 needs to be cleaned, the wireless charging body 2 can be disassembled first, and then assembled and used after the floor mat 1 is cleaned.

[0060] Preferably, the floor mat 1 and the wireless charging body 2 are regarded as a whole, and the total height of this whole is between 0.5 cm and 5 cm.

[0061] It can be understood that such a design is to prevent the floor mat 1 from being too thick and affecting the anthropomorphic robot from moving onto the floor mat 1 for charging.

[0062] Since the floor mat 1 is likely to accumulate dust during long-term use, therefore, as Figure 7 shown, the wireless charging body 2 further includes a coating layer 21, and the coating layer 21 houses components such as the control circuit board 22 therein.

[0063] It should be noted that the coating layer 21 can be made of a hard material or a soft material. For example, the hard materials include a plastic shell or a metal shell. When a plastic shell is used, the wireless charging body 2 also has the function of insulation. It should be understood that since the floor mat 1 may get wet during use, therefore, using the coating layer 21 made of an insulating material can extend the service life of the wireless charging body 2. And since the wireless charging body 2 is disposed in the floor mat 1, and the floor mat 1 is often in a usage environment of being stepped on, therefore, using the coating layer 21 made of a hard material can also increase the pressure resistance of the wireless charging body 2 and prevent the wireless charging body 2 from being damaged by stepping.

[0064] In addition, the wireless charging body 2 can be arranged at multiple positions on the floor mat 1. In some usage scenarios, the wireless charging body 2 is arranged at the four corner positions of the floor mat 1. Regarding the specific setting position of the wireless charging body 2 on the floor mat 1, it is set according to the specific usage scenario.

[0065] It should be understood that when multiple wireless charging bodies 2 are provided on the floor mat 1, multiple anthropomorphic robots can be accommodated for charging, which is more convenient and faster.

[0066] In summary, a wireless charging floor mat device has a wireless locator 24, which can accurately guide the device to be charged to the charging area, effectively solving the problem that in the prior art, when a wireless charging floor mat charges a device, it is necessary to manually move the device to the wireless charging area, and the operation is very inconvenient.

In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
