DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present invention discloses a multi-purpose mat with wireless charging function, such as a mouse pad, a coffee table pad, a bedside table pad, etc., and can also be a yoga mat or a sports mat, etc. The present invention is not limited to the above-mentioned mats, and mats used in other scenarios can also be used. Figure 1 As shown, it includes a mat body and a wireless charging device 4 arranged on the mat body, and the mat body includes, from top to bottom, a fabric layer 2 and a substrate layer 3; the fabric layer 2 and at least a portion of the edge of the substrate layer 3 are fixedly connected, for example, the fabric layer 2 and a portion of the edge of the substrate layer 3 are bonded or glued by a hot pressing process.

[0034] The substrate layer 3 is provided with a receiving groove 31, which can be arranged on one side of the substrate layer 3 close to the edge, for placing the wireless charging device 4, wherein the bottom of the receiving groove 31 has an open opening to facilitate heat dissipation of the wireless charging device 4; the wireless charging device 4 has a power interface 41 for connecting an external power supply.

[0035] Reference Figure 2 As shown, taking a mouse pad as an example, the multi-purpose mat is placed on the desktop where it is needed and connected to a power source. The user can then place a mobile phone or other device with a wireless charging function on the wireless charging area on the mouse pad for charging, eliminating the tedious operation of connecting the mobile phone to a cable every time it is charged.

[0036] In this embodiment, a conventional mat is combined with a wireless charging device to form a multi-purpose mat, which has an interface for connecting to an external power source. From the appearance, the entire mat is very simple.

[0037] The multi-purpose mat provided by the present invention combines the wireless charging device with the mat, and the combined use does not take up too much space, which can solve the problem that a single wireless charging device is easily lost, can be conveniently applied to a variety of scenarios, and improves the user experience.

[0038] Further, see Figure 3 As shown, in order to improve the comfort of the user, the cushion body also includes a filler 1 arranged between the fabric layer 2 and the backing layer 3; in a specific implementation, the filler can be a single number or a plurality of numbers of fillers; a plurality of filling cavities 32 for fillers are arranged on the cushion body, and when the number of fillers 1 is multiple, the filler 1 and the above-mentioned wireless charging device 4 can be made to be the same size, and the backing layer 3 is provided with a plurality of filling cavities 32 that are the same size as the receiving groove 31 and are used to place the fillers; the cushion can be folded multiple times for easy storage and transportation.

[0039] Further, refer to Figure 4 As shown, the wireless charging device 4 includes: one or more wireless charging coils 6, a circuit board 5 integrated with a wireless charging circuit adapted to the wireless charging coil 6, a structural bracket 7 and a metal plate 8; it can charge multiple devices with wireless charging functions at the same time; for example, it can charge two mobile phones with wireless charging functions and an iPad with wireless charging functions at the same time.

[0040] The wireless charging coil 6 and the circuit board 5 integrated with the wireless charging circuit are installed on the structural bracket 7, and the structural bracket 7 is fixedly connected to the metal plate 8, and the metal plate 8 is embedded in the accommodating groove 31; at the same time, the heat generated by the circuit board 5 integrated with the wireless charging circuit during operation is conducted to the metal plate 8 by using thermal conductive silicone, and the base is the metal plate 8, which can effectively dissipate the heat of the circuit board 5 integrated with the wireless charging circuit during operation, and at the same time play the function of protecting the circuit board and the charging coil, so as to achieve the purpose of rapid heat dissipation.

[0041] The output end of the power interface 41 is connected to the circuit board 5 integrated with the wireless charging circuit, wherein the power interface 41 includes one or more of the following: a Micro USB charging interface, a Mini USB and a Type C interface. The embodiments of the present disclosure are not limited to this and are not limited to other forms of interfaces or other non-standard interfaces.

[0042] Reference Figure 2 As shown, the multi-purpose mat also includes a DC / AC conversion circuit connection line; the output end of the above-mentioned DC / AC conversion circuit connection line is adapted to the input end of the above-mentioned power interface 41; the input end of the above-mentioned DC / AC conversion circuit connection line is connected to the cable of the external power supply.

[0043] The above-mentioned wireless charging circuit can adapt to a variety of fast charging protocols, such as QC2.0, QC3.0, PE+2.0, PD2.0, etc., and can intelligently select the best one from them to achieve high-efficiency charging while reducing heat generation. At the same time, it also supports new fast charging protocols through software upgrades in the later stage.

[0044] Furthermore, in order to facilitate the user to use the wireless charging device 4 in different scenarios, the wireless charging device 4 inside the above-mentioned mat can be separated, that is, the wireless charging device 4 can be detachably arranged on the mat body. The multi-purpose mat also includes a wrapping structure, which wraps the wireless charging device 4 in the receiving groove 31 between the above-mentioned fabric layer 2 and the substrate layer 3.

[0045] The wrapping structure may be a zipper structure, for example, a zipper is provided on the fabric layer 2, which may be a single zipper or a double zipper structure. By adjusting the zipper position on the zipper, the wireless charging device 4 can be taken out from the receiving slot 31. This facilitates the disassembly of the wireless charging device 4 to adapt to the use of different users in different occasions. Moreover, when the cushion body is intact during use but the wireless charging device 4 fails, a new wireless charging device can be replaced.

[0046] For example, a Velcro can be set between the fabric layer 2 and the substrate layer 3. The bottom side of the fabric layer 2 can be soft fibers, and the substrate layer 3 can be elastic fibers with hooks and barbs. After the wireless charging device 4 is placed in the accommodating groove 31, the two sides of the Velcro are fastened together to fix the wireless charging device 4; the wireless charging device 4 can be easily taken out by opening the Velcro.

[0047] For example, by embedding a C-shaped metal sheet 11 in the fabric layer 2, Figure 5 As shown, the area of ​​the wireless charging device 4 is made to be flippable. Under the support of the C-shaped metal sheet 11, the area has a certain strength and is not easy to deform. The circuit board 5 with integrated wireless charging circuit and the wireless charging coil 6 are combined into an integrated wireless charging kit 9. A fixing bracket 10 of the wireless charging kit 9 ​​is made on the metal plate 8 to fix the wireless charging kit 9, and a magnet 12 is implanted inside the substrate layer 3. When the fabric layer 2 is covered, the two parts will be bonded together due to the physical effect of the magnet 12 and the C-shaped metal sheet 11, and are not easy to separate. Because the thickness of the C-shaped metal sheet 11 is very thin, and the substrate layer 3 has enough space to embed the magnet 12, the overall thickness of the mat is not increased, which is convenient for users to quickly disassemble. In this embodiment, other structures that can achieve quick disassembly are all possible, and there is no limitation on this.

[0048] Furthermore, the backing layer 3 can be made of semi-rigid materials or soft materials such as rubber and plastic, or hard materials can be selected according to specific usage occasions; the fabric layer 2 can be bonded to the backing layer by heat pressing or gluing, and when the backing layer 3 is made of soft materials, the mat can be rolled up for easy storage and transportation;

[0049] In addition, the fabric layer 2 can be made of waterproof fabric, so it has a waterproof function. Therefore, when used as a coffee table mat, there is no need to worry about water ingress. Compared with conventional wireless charging devices, it is more practical and more beautiful, and it greatly broadens the usage scenarios and can effectively extend the service life.

[0050] The embodiment disclosed in the present invention is to embed the wireless charging device into the mat body, and then connect the power supply through, for example, a MicroUSB interface, thereby realizing the integration of the mat and the wireless charging. Conventional wireless charging devices are devices placed on the desktop, which are not convenient for sorting and storage. The multi-purpose mat provided by the embodiment of the present invention combines the wireless charging function with the mat body, eliminating the trouble of storage and sorting, and the material of the fabric layer of the mat body has a very wide range of choices, and various patterns can be freely customized on the surface of the fabric layer, which is more colorful, enhances the user's visual experience, and is more convenient to use.

[0051] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
