[0032] like Figure 1-Figure 3 The present disclosure provides a ring-worn device, which includes an annular shell 1, a bracket 2 and a flexible circuit board 3. The annular shell 1 may include an annular groove 11 arranged on the inner side, for example, the annular groove 11 can be said to be formed by being recessed inward from the inner surface of the annular shell 1, and the annular groove 11 is arranged around the axis of the annular shell 1. The ring-worn device may include a plurality of brackets 2, each of which is partially arranged in the annular groove 11, and the bracket 2 can move radially in the annular groove 11 relative to the annular shell 1, and the inner wall of the annular groove 11 can limit the radial movement trajectory of the bracket 2 in the annular shell 1, for example, a slide groove or a slide rail can be formed on the inner wall of the annular groove 11. The bracket 2 is only partially arranged in the annular groove 11, so the surface of each bracket 2 facing the middle of the annular shell 1 can form a part of the skin contact surface of the ring-worn device, that is, when the user wears the ring-worn device, the surface of the bracket 2 facing the annular shell 1 contacts the user's skin.
[0033] The flexible circuit board 3 includes a wiring area 31 and a retractable area 32 located between adjacent wiring areas 31. The wiring area 31 is arranged on the surface of the bracket 2 away from the middle of the annular housing 1. The wiring area 31 and the bracket 2 are arranged in a one-to-one correspondence. For example, the wiring area 31 can be bonded to the bracket 2 by bonding. The retractable area 32 is arranged corresponding to the interval between two adjacent brackets 2. For example, the retractable area 32 can cover at least a part of the interval between two adjacent brackets 2. The number of retractable areas 32 is one less than the number of brackets 2. When the bracket 2 moves radially relative to the annular housing 1, the retractable area 32 can be driven to flatten or retract.
[0034] like Figure 1 As shown in the figure, the distance between the bracket 2 and the bottom wall of the annular groove 11 is the smallest. At this time, the retractable area 32 is flattened, and the diameter of the circle surrounded by the surface of the multiple brackets 2 facing the middle of the annular shell 1 is the largest. Figure 1 The status shown is Figure 2 When the state shown is switched, the multiple brackets 2 all move toward the middle of the annular shell 1, and the diameter of the circular axis surrounded by the surfaces of the multiple brackets 2 toward the middle of the shell 1 decreases, and the retractable area 32 is stored until the diameter of the circle surrounded by the surfaces of the multiple brackets 2 toward the middle of the shell 1 is the smallest, and the ring-worn device is switched to Figure 2 In the state shown, the retractable area 32 is completely retracted. Based on this, the inner diameter of the ring-worn device can be adaptively adjusted according to different user parameters, and design reuse is achieved for different user parameters, reducing mold opening costs. The ring-worn device may include a wristband, a finger ring, or a foot ring.
[0035] Still Figure 1 and Figure 2 As shown, the ring-worn device further includes an elastic member 4, each of which connects any bracket 2 and the annular housing 1 along the radial direction of the ring-worn device. Each bracket 2 can be connected to a single or multiple elastic members 4, and the deformation direction of the single or multiple elastic members 4 is the same as the radial direction of the annular housing 1. When the elastic member 4 is in a natural state, the ring-worn device is in Figure 2 The minimum inner diameter state shown, if Figure 2 The minimum inner diameter of the ring-worn device is smaller than the user parameters. Under the action of the user, the force acts on the elastic part 4 through the bracket 2, causing the elastic part 4 to contract, and the bracket 2 moves toward the bottom wall of the annular groove 11, and the inner diameter of the ring-worn device increases, thereby realizing adaptive adjustment of the user parameters.
[0036] In order to control the deformation direction of the elastic member 4 and prevent the elastic member 4 from moving, a stopper may be provided in the annular housing 1 to prevent the deformation of the elastic member 4. The elastic member 4 may include a spring or other flexible member, which is not limited in the present disclosure.
[0037] In some embodiments, when the length of the bracket 2 is relatively small, the bracket 2 can be provided in a strip shape; in other embodiments, the bracket 2 can be an arc bracket, and the arc bracket can be provided concentrically or unequally with the annular shell 1, and the present disclosure does not limit this.
[0038] In each of the above embodiments, the ring-worn device further includes a battery 5, which is electrically connected to the flexible circuit board 3, and the interval between the battery 5 and the adjacent bracket 2 is covered by the retractable area 32, so that when the bracket 2 moves in the radial direction, the retractable area 32 covering the interval between the bracket 2 and the battery 5 can be synchronously expanded or retracted to adapt to the movement of the bracket 2. The battery 5 can be fixedly arranged, and the movement of the bracket 2 can be adapted by the expansion and retraction and retraction of the retractable area 32 covering the battery 5 and the adjacent bracket 2; or the battery 5 can also be movably arranged along the radial direction of the annular housing 1, and subsequently under the action of the user, the battery 5 can move away from the bottom wall of the annular groove 11 or toward the bottom wall of the annular groove 11, so that the adaptive adjustment range of the inner diameter size of the ring-worn device can be increased.
[0039] In order to enrich the configuration functions of the ring-worn device and increase the applicable scenarios of the ring-worn device. The ring-worn device also includes an NFC coil 6, which is electrically connected to any wiring area 31 of the flexible circuit board 3, and the NFC coil 6 includes a base axis and a cable arranged around the base axis. Compared with the traditional flat-surrounding NFC coil structure, the NFC coil 6 provided in the present disclosure adopts a winding type, which can reduce the occupied area of the NFC coil 6 and is more suitable for the narrow internal space of the surrounding device itself.
[0040] In some embodiments, the ring-worn device further includes a heart rate sensor 7 and a temperature sensor 8, both of which can be electrically connected to the flexible circuit board 3. The heart rate sensor 7 is arranged on the surface of any bracket 2 facing the middle of the annular shell 1, so that when the user wears the ring-worn device later, the heart rate sensor 7 contacts the skin to obtain the user's heart rate. The temperature sensor 8 can be arranged on the surface of any bracket 2 facing the middle of the annular shell 1, so that when the user wears the ring-worn device later, the temperature sensor 8 contacts the skin to obtain the user's body temperature. In this way, by detecting the user's body temperature and heart rate in real time, it is convenient to keep track of the body state at all times. The heart rate sensor 7 and the temperature sensor 8 can be arranged on the same bracket 2 or different brackets 2. Optionally, the ring-worn device may also include a heart rate sensor 7 or a temperature sensor 8.
[0041] The above description is made by taking the detection sensors included in the wearable device as the heart rate sensor 7 and the temperature sensor 8 as an example. In other embodiments, the wearable device may include other detection sensors, which are electrically connected to the flexible circuit board 3 and are arranged on the surface of the bracket 2 facing the middle of the annular housing 1.
[0042] In some embodiments, Figure 4 As shown, the wearable device further includes a radiator 9, which is disposed on one side of any end bracket 2. The radiator 9 may be an onboard antenna, for example, the radiator 9 is disposed on one side of the flexible circuit board 3, and the radiator 9 is electrically connected to a feed end disposed on the flexible circuit board 3. The radiator 9 may be a portion of a copper foil trace on the flexible circuit board 3, or the radiator 9 may be a portion of a metal trace different from the flexible circuit board 3. The radiator 9 may receive or transmit electromagnetic wave signals to realize interaction between the wearable device and other terminals. Optionally, as Figure 5 As shown, the wearable device includes a radiator 9 and an antenna bracket 10 stacked on any wiring area 31, the radiator 9 is arranged on the side of the antenna bracket 10 away from the wiring area 31, and the radiator 9 is also electrically connected to the feed end arranged in the wiring area 31. Based on this, the antenna bracket 10 can be used to increase the interval between the radiator 9 and the flexible circuit board 3, so that when the user wears the wearable device, the distance between the radiator 9 and the user can be increased, and the influence of skin tissue on the radiation efficiency of the radiator 9 can be reduced.
[0043] In the above embodiment, the radiator 9 can be used to radiate Bluetooth signals. Especially when the wearable device is equipped with the radiator 9 and the NFC coil 6, a dual transmission mode of short-range signal transmission can be realized, thereby enriching the communication function of the wearable device.
