[0026] Example 1 Please refer to Figures 1-6 This embodiment provides a watch band that can provide a wireless charger, including: A connecting buckle 1 is provided at both ends with a first connecting part 110 and a second connecting part 120 respectively; a mounting cavity 130 is provided between the first connecting part 110 and the second connecting part 120; a through hole 140 communicating with the mounting cavity 130 is provided on the side of the connecting buckle 1; and a cover plate 150 for covering the mounting cavity 130 is provided on the connecting buckle 1. The shape of the connecting buckle 1 can be consistent with that of a regular watch buckle to avoid an abrupt appearance.

[0027] A wireless charging module 2 is disposed in the mounting cavity 130; the wireless charging module 2 includes a wireless charging circuit board 210 and a transmitting coil 220 connected to the wireless charging circuit board 210; the wireless charging circuit board 210 is provided with a power interface 230 corresponding to the through hole 140. The wireless charging circuit board 210 can be manufactured using existing technology and miniaturized electronic components, which may include a wireless charging main control chip, a power full-bridge chip, inductors, capacitors and other devices.

[0028] The first watch strap 3 is connected to the first connecting part 110, and the other end is provided with a first connector 310 for connecting to the watch body (not shown); The second watch strap 4 is connected to the second connecting part 120, and the other end is provided with a second connector 410 for connecting to the watch body.

[0029] In the wireless charging module 2, the transmitting coil 220 faces the cover plate 150.

[0030] When the first strap 3, the second strap 4, the connecting buckle 1, and the watch body are connected to form a closed loop, the back cover of the watch body can be placed against the outer end face of the cover plate 150. This allows the charging receiving coil of the watch body to match the transmitting coil 220 of the wireless charging module 2. Using a conventional charger, the charger plug is connected to the power interface 230 for power supply, and the transmitting coil 220 provides wireless charging power to the watch body. In this way, the watch strap itself becomes a component that provides wireless charging, eliminating the need for users to carry an additional wireless charging dock, making it more convenient. Thus, the strap provided in this application not only provides the function of a watch strap but also serves as an auxiliary charging device, offering dual functionality and enhancing the user experience. The strap is integrated with the watch body, eliminating the burden of carrying a separate dedicated charger, allowing users to carry it without any noticeable difference.

[0031] Since the connecting buckle 1 is a relatively small component of the original watch strap buckle structure, the wireless charging module 2 installed in the mounting cavity 130 is also relatively small. As a result, the wireless charging power provided is not high, and the heat generation is not large, so there is no need to provide additional heat dissipation and cooling measures.

[0032] Example 2 Please refer to Figure 7 The power output terminal can be set as a flexible terminal group 8. The watch body has a corresponding power connection point. After the conductive flexible terminal post on the flexible terminal group extends out of the end face of the connecting buckle 1, it makes an electrical contact with the power connection terminal of the watch body. When the power connection interface 230 is connected to the power supply, the watch body is charged.

[0033] Depending on the location of the terminal power connection points on the watch body, the flexible terminal group 8 can be located at different end faces of the connecting buckle 1, or it can be located on the side of the cover plate 150, so that the flexible terminal group 8 can correspond to the power connection points on the watch body. The magnetic component can be located near the flexible terminal group 8 to facilitate magnetic attraction and improve the connection strength.

[0034] Depending on the design, the number and arrangement of the conductive elastic terminal blocks in the flexible terminal block group 8 can vary. For example, it can be a basic charging model with two terminals, or a charging and data transmission model with four terminals. It can also be a model with three terminals, providing both charging and protocol verification.

[0035] Please refer to Figure 4 In some embodiments, the power interface 230 is a Type-C female interface.

[0036] In some embodiments, a magnetic suction element (not shown) is included, which is disposed in the mounting cavity 130 and in the inner hole of the transmitting coil 220.

[0037] The magnetic connector is used to connect with the iron back cover of the watch body or the corresponding magnetic connection component on the watch body to enhance the connection strength during wireless charging.

[0038] Please refer to Figure 4 It includes a sealing ring 5, which is located at the joint between the power interface 230 and the through hole 140.

[0039] This design provides waterproofing.

[0040] In some embodiments, the power interface 230 is either a Micro USB or a Lightning female interface.

[0041] Please refer to Figure 3 and Figure 4It includes a sealing gasket 6, which is disposed at the connection between the cover plate 150 and the mounting cavity 130.

[0042] Please refer to Figure 3 and Figure 4 Both the first connecting part 110 and the second connecting part 120 are through holes; both the first watch strap 3 and the second watch strap 4 are magnetic flexible watch straps.

[0043] The first connecting part 110 and the second connecting part 120 can also be selected from other structural forms in the prior art. The first watch strap 3 and the second watch strap 4 can also correspond to, but are not limited to, magnetic flexible watch straps. They can also be selected from suitable watch straps in the prior art.

[0044] Please refer to Figure 3 and Figure 4 The cover plate 150 has a connecting ring groove 151 at one end facing the mounting cavity 130, and the inner ring of the sealing gasket 6 is connected to the connecting ring groove 151; the cover plate 150 is fastened to the connecting buckle 1 by screws 7.

[0045] The present invention also provides a watch, including a watch strap that can provide a wireless charger as described above; the two ends of the main body of the watch are detachably connected to the first connector 310 and the second connector 410 respectively; the main body of the watch is provided with a charging receiver corresponding to the power output end.

[0046] The charging receiver can be a charging receiving coil located inside the watch body, or it can be a power terminal exposed on the end face of the watch body.

[0047] The first connector 310 and the second connector 410 can be plug structures from the prior art, and the main body of the watch has corresponding connection slots at both ends.
