[0053] As Figure 1-6 shown, the present application provides a chargeable smart watch band embodiment.

[0054] The rechargeable smart watch strap 2 includes a first strap body 22 and a second strap body 21, each of which is connected to the smart watch 1 at one end. A connecting mechanism (not shown in the drawings) is provided between the other ends of the first strap body 22 and the second strap body 21. The first strap body 22 is provided with a flexible connection circuit charging coil 224, a charging interface 5 and a control circuit 6. The control circuit 6 is electrically connected to the charging coil 224. When controlled, after the first strap body 21 is folded, the charging coil 224 forms a wireless charging circuit with the charging receiving coil (not shown in the drawings) on the smart watch 1. The control circuit 6 controls the connection with the external power supply through the charging interface 5, and the charging coil 224 charges the smart watch 1. The first strap body 22 may be equipped with a battery 3. When the first strap body 22 has a built-in battery, the control circuit 6 controls the battery 3 to charge the smartwatch 1 via the flexible connection circuit and charging coil 224. Alternatively, the control circuit 6 controls an external power source to charge the battery 3 via the charging port 5 and the flexible connection circuit. When the control circuit 6 controls external power source charging, the smartwatch 1 is charged via the charging port 5, the flexible connection circuit, and the charging coil 224. Specifically, when equipped with a battery 3, the battery 3, the flexible connection circuit, the charging coil 224, the charging port 5, and the control circuit 6 may be located within the first strap body 22, with the charging port 5 located at one end of the first strap body 22. The battery 3 is distributed, meaning multiple battery blocks are connected in series and / or in parallel. When the first strap body 22 does not have a battery 3, the charging port 5, the battery 3, the flexible connection circuit, the charging coil 224, and the control circuit 6 may be located within the first strap body 22 or, if desired, within the second strap body 21. This embodiment uses the first strap body 22 as an example. The charging port 5 can be a universal port, such as a Type-C port. When the first strap body 22 contains a battery 3, the first strap body 22 has cavities (not shown) for accommodating the battery 3, the control circuit 6, and the charging coil 224. Each cavity is independently configured. The first strap body 22 and the second strap body 21 can be made of an elastic material, including silicone. The battery 3, the control circuit 6, and the charging coil 224 are connected to each other via a flexible connection circuit, including an FPC, for electrical signal communication. The control circuit 6 is provided with an indicator light to indicate the battery level.

[0055] The first band 22 comprises a first connecting part 221, a second connecting part 220 and a bending part 222, wherein the first connecting part 221 is connected with the smart watch 1, and the bending part 222 connects the first connecting part 221 and the second connecting part 220. When the bending part 222 is bent greatly when the first band 22 charges the smart watch 1, the bending angle of the bending part 222 is not less than 90° from the use state to the charging state when the first connecting part 221 does not rotate with the smart watch 1. The bendability of the bending part 222 is at least not less than the bendability of the first connecting part 221 and the second connecting part 220. For example, when the bending part 222, the first connecting part 221 and the second connecting part 220 are made of the same material and have the same thickness and width, the bendability of the three parts is basically the same.

[0056] In order to more easily form a good charging contact state between the charging coil 224 and the charging receiving coil of the smart watch 1 when charging, and facilitate bending, the bendability of the bending part 222 is higher than that of the first connecting part 221 and the second connecting part 220. Preferably, the bendability of the bending part 222 is greater than that of the first connecting part 221, and the bendability of the first connecting part 221 is greater than that of the second connecting part 220. The bendability refers to the deformation of the bending part. The bending part 222 is internally provided with a plurality of bending cavities (not shown in the drawing) arranged along the length direction of the first band 22, and the cross section of the bending cavities in the length direction is prismatic, so that the bending cavities are more easily deformed when bent. According to needs, a plurality of cavities (not shown in the drawing) are also arranged in the width direction of the first band 22 to make the first band 22 fold in parallel with the smart watch 1, and the cross section of the cavities in the length direction is prismatic, so that the cavities are more easily deformed when bent.

[0057] The first band 22 and the second band 21 are provided with a magnetic control switch 223 connected with the control circuit 6, wherein the magnetic control switch 223 is arranged on the first band 222, and the second band 21 is provided with a magnetic block 211 matched with the magnetic control switch 223. When the first band 220 charges the smart watch 1, the magnetic control switch 223 is triggered by the magnetic block 211, and the smart watch 1 is charged by the charging coil 224 under the control of the control circuit 6. Through the cooperation of the magnetic control switch 223 and the magnetic block 211, automatic control of charging after folding can be realized.

[0058] In order to ensure that the charging receiving coil on the watch body 1 and the charging coil 224 on the first strap body 22 can be in the optimal charging position after bending, a first magnetic attraction component (not shown in the drawings) for calibrating and fixing the charging position is provided between the charging receiving coil on the watch body 1 and the charging coil 224 on the first strap body 22. The first magnetic attraction component includes an annular magnetic component provided on the watch body 1 and a first magnetic attraction component (not shown in the drawings) provided on the first strap body 22. The first magnetic attraction component is located around the charging coil, including inside or outside. During charging, the first magnetic attraction component is attracted to the annular magnetic component.

[0059] In order to ensure the stability of the connection during charging, a second magnetic component (not shown in the drawings) is provided between the first strap body 22 and the second strap body 21. When the first strap body 22 charges the smart watch 1, the two magnetic components are attracted and fixed.

[0060] When charging the watch body 1 is required, the first strap 22 is bent, even if the bending portion 222 is bent, so that the charging coil 224 on the second connecting portion 220 is in parallel contact with the charging receiving coil on the watch body 1. The charging coil 224 and the charging receiving coil are aligned and fixed by the magnetic attraction component. When the magnetic switch 223 on the first strap 22 contacts the magnetic block 211 of the second strap 21, the magnetic switch 223 is triggered. At this time, the control circuit 6 controls the charging coil 205 to charge the smart watch 1, thereby replenishing the power of the smart watch 1 in a timely manner. Since the user can replenish the power through a universal charging cable or use the built-in battery to charge the smart watch without having to carry a dedicated charger, it is convenient to use and improves the user experience. The control circuit 6 is provided with an indicator light to display the battery 3 power level, so that the battery level in the strap can be instantly understood.

[0061] like Figure 7-13 As shown, the present invention provides another embodiment of a rechargeable smart watch strap.
