[0024] Please refer to Figures 1 to 5As shown in the figure, the present invention provides a wearable device 100, which includes a support ring 1, an outer ring 2 and a flexible circuit board 3. The outer ring 2 is sleeved on the support ring 1 and is rotatably connected to the support ring 1. The outer ring 2 is provided with a magnetic member 22. The flexible circuit board 3 is wound around the support ring 1 and is located between the support ring 1 and the outer ring 2. The flexible circuit board 3 is provided with a Hall sensor 32. The magnetic member 22 is configured to trigger the Hall sensor 32 to identify the rotation direction of the outer ring 2 relative to the support ring 1.
[0025] In this embodiment, the wearable device 100 is a wearable intelligent device, usually worn on parts such as the user's fingers, arms, wrists, ankles, etc. That is to say, the wearable device 100 in this application can be a smart wearable ring, a smart wearable bracelet, a smart wearable ankle ring, a smart wearable arm ring, etc., which is not limited here. The wearable device 100 of this application includes a support ring 1, an outer ring 2 and a flexible circuit board 3. Among them, the support ring 1 is a structural support component of the wearable device 100. The support ring 1 has a circular ring structure, which has a hollow part and a ring groove 13 arranged around the hollow part. The hollow part is convenient for the user to wear. The ring groove 13 is used to install and place the outer ring 2 and the flexible circuit board 3. The structure of the support ring 1 can be made of lightweight and high-strength materials such as titanium alloy and ceramic, or can be made of flexible fabric or elastic silicone rubber and other materials.
[0026] As Figures 1 to 3 shown in the figure, the outer ring 2 is sleeved on the support ring 1 and is located in the ring groove 13. The outer ring 2 can also rotate relative to the support ring 1. For example, a rotation groove is provided on the groove wall of the ring groove 13. The outer ring 2 is limited in the rotation groove and can rotate relative to the support ring 1 in the rotation groove. The outer ring 2 includes a ring body 21 and a magnetic member 22. The ring body 21 is rotatably connected to the support ring 1, that is, the ring body 21 is limited in the ring groove 13. Or, a ball bearing is provided between the ring body 21 and the support ring 1, and the inner ring of the ball bearing is connected to the support ring 1, and the outer ring of the roller bearing is connected to the ring body 21 to realize the rotational connection between the outer ring 2 and the support ring 1.
[0027] Furthermore, to improve the rotational smoothness between the outer ring 2 and the support ring 1, a diamond-like coating can be provided on the surface of the rotation groove in contact with the ring body 21 to reduce the friction coefficient. Or, grease can be provided inside the rotation groove to improve the smoothness of the outer ring 2 during rotation.
[0028] In addition, to improve the entertainment of the wearable device 100 during rotation, a plurality of ratchet grooves can be provided on one of the inside of the rotation groove and the ring body 21, and an elastic ratchet pawl is provided on the other of the inside of the rotation groove and the ring body 21. Through the short-term limit connection between the elastic ratchet pawl and each ratchet groove, a sense of jerk and click sound during rotation can be generated, improving the tactile clarity and comfort of the user when rotating the wearable device 100.
[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 5 shown, the wearable device 100 further includes a flexible circuit board 3. The flexible circuit board 3 is a bendable and deformable circuit substrate 31 with a polyimide film as the base and formed with a conductive layer through printing or etching. The flexible circuit board 3 is wound around the annular groove 13 of the support ring 1, and the flexible circuit board 3 is located between the annular body 21 of the outer ring 2 and the support ring 1. A Hall sensor 32, a wireless module, a power management module, a control module, etc. are integrated on the substrate 31 of the flexible circuit board 3. At the same time, a magnetic member 22 is provided on the annular body 21 of the outer ring 2. The magnetic member 22 is attached to the annular body 21 or embedded in the groove of the annular body 21. When the outer ring 2 rotates relative to the support ring 1, the outer ring 2 also rotates relative to the flexible circuit board 3. During the rotation process, the magnetic member 22 can trigger the Hall sensor 32 so that the Hall sensor 32 can identify the rotation direction of the outer ring 2 relative to the support ring 1.
[0030] It can be understood that when the Hall sensor 32 is affected by an external magnetic field, by measuring the change in magnetic field strength or direction (for example, using a differential Hall sensor 32 to detect the magnetic field polarity reversal), it is converted into a rotation angle or a step signal to realize the detection of the rotation direction of the outer ring 2 relative to the support ring 1. For example, the wearable device 100 in this application can be provided with at least two Hall sensors 32. The at least two Hall sensors 32 are arranged at intervals along the rotation direction of the outer ring 2 relative to the support ring 1. When the magnetic member 22 rotates with the outer ring 2 and sequentially passes through the two Hall sensors 32, the two Hall sensors 32 generate response currents at different times to determine the rotation direction of the outer ring 2 relative to the support ring 1; or, the Hall sensor 32 is a linear Hall sensor 32, and the magnetic fluxes at different parts of the magnetic member 22 are different and are arranged to gradually change along with the rotation direction of the outer ring 2 relative to the support ring 1. When the outer ring 2 drives the magnetic member 22 to rotate, the magnetic flux continuously changes, causing the output voltage of the linear Hall sensor 32 to also continuously change, such as gradually increasing or gradually decreasing, so as to judge the rotation direction of the outer ring 2 relative to the support ring 1. By rotating the outer ring 2 relative to the support ring 1, on the basis of being connected to an external intelligent wearable device, the wearable device 100 can perform more accurate and diverse control and operations on the external intelligent wearable device, effectively improving the use convenience and operation accuracy of the wearable device 100, and effectively expanding the use scenarios of the wearable device 100 and enhancing its applicability.
[0031] Of course, the wearable device 100 in the present application is not limited to the induction method between the magnetic member 22 and the Hall sensor 32 to detect the rotation direction. In the present application, concentric capacitive plates can also be arranged inside and outside the outer ring 2 and the support ring 1. During the rotation of the outer ring 2 relative to the support ring 1, the capacitance value changes with the overlapping area, so as to detect the rotation direction of the outer ring 2; alternatively, a magnetic group sensor can be arranged on the support ring 1, and the change in the magnetic field direction when the magnetic member 22 rotates with the outer ring 2 causes a change in the resistance value of the magnetic group sensor, so as to identify the rotation direction of the outer ring 2 relative to the support ring 1.
[0032] The wearable device 100 of the present technical solution includes a support ring 1, an outer ring 2 and a flexible circuit board 3. The support ring 1 is a support structure of the wearable device 100. The outer ring 2 is sleeved on the support ring 1 and is rotatably connected to the support ring 1. The outer ring 2 is provided with a magnetic member 22. The flexible circuit board 3 is wound around the support ring 1 and is located between the support ring 1 and the outer ring 2. The flexible circuit board 3 is provided with a Hall sensor 32. When the outer ring 2 rotates relative to the support ring 1, the magnetic member 22 arranged on the outer ring 2 can trigger the Hall sensor 32 to identify the rotation direction of the outer ring 2 relative to the support ring 1. The wearable device 100 determines the operation intention when the user manipulates the outer ring 2 by identifying the rotation direction of the outer ring 2 relative to the support ring 1. Thus, when the wearable device 100 interacts with other intelligent wearable devices such as intelligent glasses and intelligent earphones outside, effective control of such intelligent wearable devices can be achieved, and the accuracy and convenience of controlling such intelligent wearable devices can be improved.
[0033] In an embodiment, as Figure 4 shown, the magnetic member 22 includes a first end 221 and a second end 222. The first end 221 and the second end 222 are arranged in sequence along the rotation direction of the outer ring 2 relative to the support ring 1; the magnetic flux of the first end 221 is less than the magnetic flux of the second end 222.
[0034] In this embodiment, the magnetic member 22 includes a connected first end 221 and a second end 222, that is, the magnetic member 22 is generally arranged to extend along the rotation direction of the outer ring 2 relative to the support ring 1, and the first end 221 and the second end 222 are arranged in sequence along the rotation direction of the outer ring 2 relative to the support ring 1. Among them, the magnetic member 22 is an integral structure, that is, the first end 221 and the second end 222 are an integrally formed complete magnet structure, or the magnetic member 22 is a split structure, and the first end 221 and the second end 222 are a split connection structure.
[0035] Furthermore, the magnetic flux of the magnetic member 22 at the first end 221 is less than that at the second end 222, so that the magnetic member 22 forms an asymmetric magnetic pole distribution. When the outer ring 2 drives the magnetic member 22 to rotate relative to the Hall sensor 32, the magnetic member 22 and the Hall sensor 32 interact with each other. Specifically, when the outer ring 2 rotates relative to the support ring 1, the first end 221 of the magnetic member 22 first passes by the Hall sensor 32, and the second end 222 of the magnetic member 22 then passes by the Hall sensor 32. At this time, the magnetic flux of the magnetic member 22 is set to gradually increase. The Hall sensor 32 can output a voltage signal characteristic waveform that first rises rapidly and then gradually decreases gently according to the changing trend of the magnetic flux increasing from the first end 221 to the second end 222, so as to realize the detection of the rotation direction of the outer ring 2 relative to the support ring 1. And it can be defined that the outer ring 2 rotates relative to the support ring 1 in one of the clockwise or counterclockwise rotation directions. At the same time, it can also be that the second end 222 of the magnetic member 22 first passes by the Hall sensor 32, and the first end 221 of the magnetic member 22 then passes by the Hall sensor 32, so as to define the outer ring 2 rotates relative to the support ring 1 in the other of the clockwise or counterclockwise rotation directions, which is not limited here.
[0036] Of course, the magnetic flux of the first end 221 can also be greater than that of the second end 222. Here, the rotation direction of the outer ring 2 can be adaptively set according to the order of the first end 221 and the second end 222 of the magnetic member 22 passing by the Hall sensor 32, which will not be elaborated here.
[0037] It can be understood that for the asymmetric magnetic pole arrangement of the first end 221 and the second end 222 of the magnetic member 22, the magnetic fluxes of the first end 221 and the second end 222 can be adjusted according to the magnet volume, magnetic surface area, magnet material, magnetization direction, etc., so as to achieve that the magnetic flux of the first end 221 is less than the magnetic flux of the second end 222, or the magnetic flux of the first end 221 is greater than the magnetic flux of the second end 222. Specifically, taking the case where the magnetic flux of the first end 221 is less than the magnetic flux of the second end 222 as an example, the thickness of the magnet can be set to increase linearly from the first end 221 to the second end 222, such as keeping the taper angle between 5° and 10°, so that the magnet volume of the first end 221 is less than the magnet volume of the second end 222, thereby making the first end 221 have a smaller magnetic flux; or when the magnetic member 22 has a uniform thickness, the cross-sectional area of the magnetic member 22 along the rotation direction of the outer ring 2 relative to the support ring 1 gradually increases from the first end 221 to the second end 222, which can also make the magnet volume of the first end 221 less than the magnet volume of the second end 222. For example, in the direction perpendicular to the rotation direction of the outer ring 2 relative to the support ring 1, the cross-sectional shape of the magnetic member 22 can be a sector, a triangle, a trapezoid, etc., which is not limited here; or, the magnetic member 22 is a split structure, a ferrite magnetic material with a smaller magnetic energy product is used at the first end 221, and a rare earth permanent magnet material with a larger magnetic energy product (such as a neodymium iron boron permanent magnet) is used at the second end 222, so as to achieve that the magnetic flux of the first end 221 is less than the magnetic flux of the second end 222.
[0038] Among them, by setting the magnetic fluxes of the magnetic member 22 at the first end 221 and the second end 222 to be different, during the rotation of the magnetic member 22 with the outer ring 2, a continuously changing voltage signal characteristic waveform is triggered in the Hall sensor 32, so as to judge the rotation direction of the outer ring 2 relative to the support ring 1. By rotating the outer ring 2 relative to the support ring 1, on the basis of the wearable device 100 being connected to an external intelligent wearable device, the wearable device 100 can perform more accurate and diverse control and operations on the external intelligent wearable device, effectively improving the use convenience and operation accuracy of the wearable device 100, and effectively expanding the use scenarios of the wearable device 100 and enhancing its applicability.
[0039] In one embodiment, as Figure 1 and Figure 4 shown, the magnetic member 22 includes at least two magnetic strips 223, one ends of the magnetic strips 223 are connected to form the first end 221; the magnetic strips 223 are arranged at an angle to each other and extend away from the first end 221 to form the second end 222.
[0040] In this embodiment, the magnetic member 22 includes at least two magnetic strips 223. Each of the magnetic strips 223 can be integrally formed to form the magnetic member 22, or can be assembled and connected separately to form the magnetic member 22. One ends of the magnetic strips 223 are connected to form a first end 221. At the same time, each of the magnetic strips 223 extends away from the first end 221 to form a second end 222, so that the magnetic strips 223 are arranged radially, and two adjacent magnetic strips 223 are spaced at a certain angle, such as greater than 10° and less than 90°.
[0041] Moreover, each of the magnetic strips 223 can be disposed in the same annular plane, or can be arranged at a three-dimensional angle in space. For example, at least three magnetic strips 223 enclose to form a spatial cone structure, so that the volume of the magnetic member 22 gradually increases from the first end 221 to the second end 222, and further the magnetic flux of the magnetic member 22 gradually increases from the first end 221 to the second end 222.
[0042] Of course, each of the magnetic strips 223 can also be connected at the second end 222 and arranged at an angle, and at the same time extend away from the second end 222 to form a first end 221, so that the magnetic flux of the magnetic member 22 gradually increases from the second end 222 to the first end 221.
[0043] It can be understood that by setting the magnetic strip 223 structure to form the magnetic member 22 with a radial structure, on the basis of changing the magnetic flux of the magnetic member 22 from the first end 221 to the second end 222, the material usage of the magnetic member 22 is reduced, and there is no need to use a completely covered magnetic member 22. Moreover, it can specifically adapt to the ring body 21 of the outer ring 2, so as to be easily installed on the ring body 21. For example, the magnetic strip 223 is set to extend in an arc curve to better fit the ring body 21.
[0044] In one embodiment, as Figure 4 shown, the outer ring 2 includes a ring body 21 and a magnetic member 22. The ring body 21 has an inner surface, and the inner surface faces the support ring 1; the magnetic member 22 is disposed on the inner surface.
[0045] It can be understood that the ring body 21 is the main support structure of the outer ring 2. The ring body 21 is arranged in a circular ring structure. The ring body 21 has an inner surface facing the support ring 1 and an outer surface facing away from the inner surface. The magnetic member 22 can be disposed on the inner surface. Specifically, the ring body 21 is provided with a groove on the inner surface, and the magnetic member 22 is limited in the groove, or the magnetic member 22 is attached to the inner surface. By disposing the magnetic member 22 on the inner surface, a part of the magnetic flux of the magnetic member 22 can be blocked from diffusing from the outer surface by the ring body 21, so as to reduce the magnetic leakage of the magnetic member 22. At the same time, the overall beauty and smoothness of the outer ring 2 can be maintained, the influence of the convex structure on the use comfort can be avoided, and the space occupied by the magnetic member 22 can also be reduced.
[0046] In one embodiment, asFigure 4 As shown in the figure, the outer ring 2 includes a plurality of magnetic members 22. The plurality of magnetic members 22 are spaced along the direction in which the outer ring 2 rotates relative to the support ring 1 and are provided on the ring body 21; the first ends 221 of the respective magnetic members 22 all face the same side of the direction in which the outer ring 2 rotates relative to the support ring 1.
[0047] In this embodiment, the outer ring 2 includes a plurality of magnetic members 22. The plurality of magnetic members 22 are all provided on the ring body 21 and are spaced along the rotation direction of the outer ring 2 relative to the support ring 1, so that the respective magnetic members 22 are arranged at equal angular intervals along the circumferential direction of the outer ring 2, forming a uniform magnetic field period. At the same time, the first ends 221 of the respective magnetic members 22 are all located on the same side of the rotation of the outer ring 2 relative to the support ring 1. When the outer ring 2 and the respective magnetic members 22 rotate synchronously, the Hall sensor 32 can first sense the first ends 221 of the respective magnetic members 22, so that the Hall sensor 32 can continuously obtain the rotation direction information of the outer ring 2 relative to the support ring 1 and can output corresponding operation instructions through the wearable device 100.
[0048] It can be understood that by providing a plurality of magnetic members 22, a dense periodic magnetic field is formed in the outer ring 2, so that when each magnetic member 22 passes by the Hall sensor 32, the Hall sensor 32 can effectively sense the magnetic field to obtain more sampling points, facilitating the user to effectively detect when rotating the outer ring 2 at any position, thereby improving the detection accuracy of the rotation direction and rotation angle of the outer ring 2. On the basis of the wearable device 100 being connected to an external intelligent wearable device, the wearable device 100 can perform more accurate and diverse control and operation on the external intelligent wearable device, effectively improving the use convenience and operation accuracy of the wearable device 100.
[0049] In one embodiment, the outer ring 2 further includes a magnetic barrier. The magnetic barrier is provided on the ring body 21 and is located between two adjacent magnetic members 22; the projection of the magnetic barrier on the magnetic member 22 covers at least a part of the magnetic member 22.
[0050] It can be understood that the magnetic barrier is a functional component for isolating the magnetic field interference between adjacent magnetic members 22. The magnetic barrier can be a solid isolation member such as a long strip shape or an arc shape, or can be a hollow groove or cavity structure. By arranging the magnetic barrier between two adjacent magnetic members 22 and the projection of the magnetic barrier on the magnetic member 22 along the rotation direction of the outer ring 2 relative to the support ring 1 can cover at least a part of the magnetic member 22. By providing the magnetic barrier, the magnetic force lines generated by two adjacent magnetic members 22 are difficult to pass through the area of the magnetic barrier, so that it is possible to avoid generating more closed magnetic circuits between two adjacent magnetic members 22, reduce the magnetic leakage between the magnetic members 22, and increase the effective magnetic flux of the magnetic members 22, thereby improving the induction intensity between the magnetic members 22 and the Hall sensor 32, improving the detection sensitivity and signal-to-noise ratio of the Hall sensor 32, and significantly improving the detection accuracy and reliability of the wearable device 100.
[0051] In one embodiment, the flexible circuit board 3 includes at least two Hall sensors 32, and the two Hall sensors 32 are spaced along the direction in which the outer ring 2 rotates relative to the support ring 1; it can be understood that the flexible circuit board 3 may include two, three, four or more Hall sensors 32. Taking the flexible circuit board 3 including two Hall sensors 32 as an example, the two Hall sensors 32 are spaced 90° along the direction in which the outer ring 2 rotates relative to the support ring 1, so that the two Hall sensors 32 are arranged orthogonally. Thus, when the outer ring 2 rotates relative to the support ring 1, the magnetic members 22 pass through the two Hall sensors 32 respectively with an angular difference of 90°, so that the phase difference between the characteristic waveforms of the sine voltage signals or the cosine voltage signals output by the two Hall sensors 32 is 90°, which is convenient for calculating the rotation angle using the arctangent function and determining clockwise rotation or counterclockwise rotation according to the change trend of the calculated angle. Specifically, the output voltage of Hall sensor A 32 is , and the output voltage of Hall sensor B 32 is . Using the arctangent function, it can be calculated that , where θ is the rotation angle and K is the magnetic field strength coefficient.
[0052] Or the flexible circuit board 3 includes three Hall sensors 32, and the three Hall sensors 32 are spaced at an included angle of 120° along the direction in which the outer ring 2 rotates relative to the support ring 1; or, the flexible circuit board 3 includes four Hall sensors 32, and the four Hall sensors 32 are spaced at an included angle of 90° from each other along the direction in which the outer ring 2 rotates relative to the support ring 1. Among them, the flexible circuit board 3 with three Hall sensors 32 or four Hall sensors 32 can be arranged around the support ring 1 to form an annular array, so as to improve the detection accuracy, realize continuous high-precision angle detection, and can perform more accurate and diverse control and operation on the external intelligent wearable device, effectively improving the use convenience and operation accuracy of the wearable device 100.
[0053] In one embodiment, as Figure 2 and Figure 3 shown, the wearable device 100 further includes a pressure sensor 4. The pressure sensor 4 is arranged in a ring shape, the pressure sensor 4 is arranged on the outer ring 2 and sleeved on the support ring 1; the pressure sensor 4 is electrically connected to the flexible circuit board 3.
[0054] It can be understood that the pressure sensor 4 is a flexible thin-film pressure sensor 4. The pressure sensor 4 is in the shape of a thin film and is arranged in a ring shape on the side of the outer ring 2 facing the support ring 1, that is, the pressure sensor 4 is arranged on the inner surface of the ring body 21. For example, a circular groove is arranged on the inner surface to limit the pressure sensor 4 in the groove. At the same time, a convex array can be arranged on the side of the support ring 1 facing the pressure sensor 4. When the user presses the outer ring 2, the outer ring 2 drives the pressure sensor 4 to deform, and the pressure sensor 4 abuts against the convexes. At the same time, the pressure sensor 4 is electrically connected to the flexible circuit board 3, so that the user's pressing action can be acquired by the pressure sensor 4 in the form of an electrical signal, and the wearable device 100 can perform operations related to pressing and clicking on the external intelligent wearable device, so that on the basis of being connected to the external intelligent wearable device, the wearable device 100 can perform more accurate and diverse control and operations on the external intelligent wearable device, effectively improving the use convenience and operation accuracy of the wearable device 100.
[0055] In one embodiment, as Figure 2 shown, the pressure sensor 4 includes a pressing part 41 and two conductive parts 42. The conductive parts 42 are in a ring shape, and the two conductive parts 42 are arranged in parallel at intervals. The pressing part 41 is at least located between the two conductive parts 42; the wearable device 100 further includes two conductive members 33, and the two conductive members 33 are arranged in parallel at intervals on the flexible circuit board 3 and are electrically connected to the flexible circuit board 3. Each conductive member 33 abuts against a conductive part 42 to electrically connect the pressure sensor 4 and the flexible circuit board 3.
[0056] In this embodiment, the two conductive parts 42 are arranged in a ring shape, and the two conductive parts 42 are arranged in parallel at intervals as concentric circles. The two conductive parts 42 are arranged on the inner wall of the pressure sensor 4 facing the support ring 1. The conductive parts 42 can be the copper leakage areas of the self-conductive layer of the pressure sensor 4 or separately arranged ring-shaped strip-shaped conductive strips, which are not limited here. Among them, the pressing part 41 is at least located between the two conductive parts 42, and can also be located between the conductive part 42 and the edge of the pressure sensor 4. When the user presses the pressing part 41, the pressing part 41 deforms, which can be acquired by the pressure sensor 4 in the form of an electrical signal, and the wearable device 100 can perform operations related to pressing and clicking on the external intelligent wearable device, so that on the basis of being connected to the external intelligent wearable device, the wearable device 100 can perform more accurate and diverse control and operations on the external intelligent wearable device.
[0057] Among them, the conductive member 33 can be a brush, such as a carbon brush or a metal conductive terminal, or an elastic conductive member 33, such as conductive silicone rubber, so that during the rotation of the pressure sensor 4 with the outer ring 2, the conductive portion 42 can always maintain a sliding contact with the conductive member 33, thereby ensuring that the pressure sensor 4 can also maintain electrical conduction with the flexible circuit board 3 during rotation. Preferably, the conductive member 33 can be made of conductive silicone rubber, so that when the pressure sensor 4 rotates with the outer ring 2 and / or when the pressure sensor 4 is pressed, the conductive member 33 can generate a certain deformation by itself to maintain effective electrical conduction between the pressure sensor 4 and the flexible circuit board 3, and restore its shape after the rotation and pressing are completed to maintain good connection, thereby improving the reliability and stability of the wearable device 100.

[0060] It can be understood that by providing the limiting protrusion 14, the ring groove 13 is formed with a first space 131 and a second space 132 arranged in sequence along the depth direction of the ring groove 13. Among them, the outer ring 2 and the pressure sensor 4 are located in the first space 131, and the outer ring 2 rotatably abuts against the limiting protrusion 14, that is, the outer ring 2 rotates relative to the support ring 1 in the first space 131. At the same time, the flexible circuit board 3 is sleeved on the collar 11 and is located in the second space 132. The wearable device 100 further includes components such as a battery, which are also provided on the collar 11 and are located in the second space 132.

The outer ring 2 that rotates relative to the support ring 1, the pressure sensor 4, etc. are arranged in the first space 131. While maintaining rotation, they are separated from the flexible circuit board 3 located in the second space 132 without interference, improving the operability and use convenience of the wearable device 100.

The flexible circuit board 3 is also provided with a controller, and both the gyroscope 5 and the acceleration sensor 6 are electrically connected to the controller on the flexible circuit board 3.
[0064] By setting the gyroscope 5, angular velocity data can be provided for the controller.
