[0024] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

In addition, "and / or" in the specification means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0026] The annular wearable device and the control method provided by the embodiments of the present application will be described in detail below with reference to the drawings, specific embodiments and application scenarios.

[0027] Please refer to Figures 1-5The embodiment of the present application provides a ring-shaped wearable device, which comprises an inner ring body 100, an outer ring body 200, a biological sensor 300, a circuit board and a driving assembly 400, the outer ring body 200 is internally provided with a containing cavity 210, the inner ring body 100, the circuit board and the driving assembly 400 are arranged in the containing cavity 210 respectively, the biological sensor 300 is fixedly connected with the inner ring body 100, and the biological sensor 300 and the driving assembly 400 are electrically connected with the circuit board respectively.

[0028] The inner ring body 100 and the outer ring body 200 are coaxially arranged, the driving assembly 400 is connected with the inner ring body 100, and the circuit board is used for controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 according to the signal quality of the biological sensor 300.

[0029] The ring-shaped wearable device can be various ring-shaped smart wearable devices, for example, can be a smart ring, a smart bracelet, a smart arm ring, a smart watch and the like. In order to facilitate understanding, the structure and working principle of the ring-shaped wearable device provided by the embodiment of the present application are further explained by taking the ring-shaped wearable device as a smart ring.

[0030] The inner ring body 100 and the outer ring body 200 can be circular rings respectively. The outer ring body 200 can be a hollow structure to form the containing cavity 210 in the outer ring body 200, and the containing cavity 210 can be a ring-shaped containing cavity 210, and the axis of the ring-shaped containing cavity 210 coincides with the axis of the outer ring body 200.

[0031] The biological sensor 300 can be various biological sensors 300 for detecting human physiological data, wherein the human physiological data can be heart rate, blood oxygen, body temperature, sleep and other health physiological data.

[0032] The circuit board can be various control circuit boards or control chips in the ring-shaped wearable device. The driving assembly 400 can be various driving assemblies 400 capable of driving the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, for example, can be various driving assemblies 400 similar in principle to brushless motors, or other driving assemblies 400 with the same function.

[0033] The signal quality of the biosensor 300 can refer to the signal quality of the detection signal output by the biosensor 300. The signal quality can be evaluated by using various common signal quality evaluation methods in the related art. For example, the signal quality can be evaluated by using the signal-to-noise ratio (SNR), the bit error ratio (BER), the channel capacity, the signal strength test, the noise test, the linear distortion test, the nonlinear distortion test, or the like.

[0034] Referring to Figure 3 Fig. 4 is a schematic diagram of the blood vessel distribution of the palm of a human body. As shown in Fig. 4, A represents the proper digital artery, and B represents the principal artery of the thumb. The proper digital artery A is located on the side of the finger. In the case of the smart ring, the biosensor 300 emits light, and a part of the light is absorbed and a part of the light is reflected. The related detection element of the biosensor 300 detects the intensity of the reflected light and converts the intensity into a digital signal. The physiological index, such as the heart rate and the blood oxygen, can be output by using an algorithm. The reflected light is mainly reflected by the blood. Therefore, the data acquisition effect is usually good when the biosensor 300 of the smart ring is opposite to the proper digital artery A. The data acquisition effect is poor when the biosensor 300 of the smart ring is opposite to other positions. The signal quality is positively correlated with the reflection effect of the reflected light. Different digital signals are converted from different reflected lights. Therefore, the corresponding relationship between the different digital signals and the signal quality can be determined in advance. The signal quality can be determined according to the corresponding relationship by using the digital signal output by the biosensor 300.

[0035] It can be understood that the relative position between the outer ring body 200 and the finger remains unchanged during the rotation of the inner ring body 100 relative to the outer ring body 200 driven by the driving assembly 400. The inner ring body 100 drives the biosensor 300 to rotate around the finger. Therefore, the signal quality of the signal output by the biosensor 300 can be improved by rotating the biosensor 300 to the position opposite to the proper digital artery A. The accuracy of the physiological data output by the ring-shaped wearable device can be improved.

[0036] In the embodiment, when the annular wearable device is in the wearing state, the circuit board can control the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 according to the signal quality of the biological sensor 300, and the biological sensor 300 is fixedly connected to the inner ring body 100. Therefore, the biological sensor 300 can be driven to rotate synchronously with the inner ring body 100 during the rotation of the inner ring body 100, thereby facilitating the rotation of the biological sensor 300 to a position with better signal quality. In this way, the data acquisition effect of the biological sensor 300 can be improved, and the accuracy of the physiological data output by the annular wearable device can be improved.

[0037] Optionally, the inner side wall of the outer ring body 200 is provided with an annular opening 220 opposite to the inner side wall of the inner ring body 100, the axis of the annular opening 220 coincides with the axis of the outer ring body 200, the biological sensor 300 is embedded in the inner side wall of the inner ring body 100, and the detection part of the biological sensor 300 faces the annular opening 220.

[0038] The inner side wall of the inner ring body 100 is located outside the inner side wall of the outer ring body 200, and the inner side wall of the inner ring body 100 blocks the annular opening 220. The inner side wall of the inner ring body 100 and the inner side wall of the outer ring body 200 form a stepped position 230 at the edge of the annular opening 220.

[0039] Please refer to Figure 1 and Figure 2 The inner side wall of the outer ring body 200 refers to the innermost side wall of the outer ring body 200, i.e., the side wall of the outer ring body 200 facing the central hole. Correspondingly, the inner side wall of the inner ring body 100 refers to the innermost side wall of the inner ring body 100, i.e., the side wall of the inner ring body 100 facing the central hole. The width of the inner side wall of the inner ring body 100 can be greater than the width of the annular opening 220, so that the inner side wall of the inner ring body 100 can block the annular opening 220, thereby sealing the accommodation cavity 210.

[0040] Please further refer to Figure 2Since the inner side wall of the inner ring body 100 and the inner side wall of the outer ring body 200 form a step position 230 at the edge of the annular opening 220, when a user wears the annular wearable device, the distance between the inner side wall of the inner ring body 100 and the skin of the user is greater than the distance between the inner side wall of the outer ring body 200 and the skin of the user, so that the inner side wall of the outer ring body 200 can be directly in contact with the skin of the user, and the distance between the inner side wall of the inner ring body 100 and the skin of the user is relatively large, so that the contact between the inner side wall of the inner ring body 100 and the skin of the user can be reduced, so that in the process of driving the inner ring body 100 to rotate relative to the outer ring body 200 by the driving assembly 400, since the outer ring body 200 is directly in contact with the skin of the user, the friction between the outer ring body 200 and the skin of the user is poor, so that in the process, the relative position between the outer ring body 200 and the skin of the user remains unchanged, and the friction between the inner ring body 100 and the skin of the user is small, so that the driving assembly 400 can drive the inner ring body 100 to rotate relative to the outer ring body 200, and in the process, the inner ring body 100 can also rotate relative to the skin of the user, so that the biological sensor 300 can cover the position opposite to the skin of the user.

[0041] The detection part of the biological sensor 300 described above refers to a collection part for collecting reflected light of skin tissue, that is, a part of the biological sensor 300 opposite to the detected object, and the detection part can also be called a sensing surface or a detection surface.

[0042] It should be noted that in the process of driving the inner ring body 100 to rotate by the driving assembly 400, the biological sensor 300 can perform circumferential motion around the axis of the annular opening 220, and the detection part of the biological sensor 300 can always face the annular opening 220.

[0043] In this embodiment, by opening the annular opening 220 opposite to the inner side wall of the inner ring body 100 on the inner side wall of the outer ring body 200, and making the detection part of the biological sensor 300 face the annular opening 220, so that when the user wears the annular wearable device, the detection part can pass through the annular opening 220 and be opposite to the skin of the user, thereby facilitating the biological sensor 300 to collect health physiological data of the user. In addition, by making the inner side wall of the inner ring body 100 and the inner side wall of the outer ring body 200 form a step position 230 at the edge of the annular opening 220, the friction between the inner ring body 100 and the skin of the user can be reduced, thereby facilitating the driving assembly 400 to drive the inner ring body 100 to rotate relative to the finger of the user.

[0044] Optionally, the friction coefficient of the inner side wall of the inner ring body 100 is smaller than the friction coefficient of the inner side wall of the outer ring body 200.

[0045] In some embodiments of the present application, in order to increase the friction coefficient of the inner side wall of the outer ring body 200, a high-friction sanding process can be used to treat the inner side wall of the outer ring body 200 to increase the friction between the inner side wall of the outer ring body 200 and the user's fingers. In addition, the inner side wall of the inner ring body 100 can also be polished to reduce the friction coefficient of the inner side wall of the inner ring body 100, thereby reducing the friction between the inner side wall of the inner ring body 100 and the user's fingers.

[0046] In this embodiment, by making the friction coefficient of the inner side wall of the inner ring body 100 less than the friction coefficient of the inner side wall of the outer ring body 200, the friction between the inner side wall of the outer ring body 200 and the user's fingers is increased, so that the relative position between the outer ring body 200 and the user's fingers remains unchanged during rotation of the inner ring body 100, and the friction between the inner side wall of the inner ring body 100 and the user's fingers is reduced, thereby facilitating control of the rotation of the inner ring body 100 relative to the user's fingers.

[0047] Optionally, the accommodating cavity 210 includes a first annular inner wall, and the first annular inner wall is opposite to the outer side wall of the inner ring body 100;

[0048] The drive assembly 400 includes a first drive module and a second drive module, one of the first drive module and the second drive module is arranged on the first annular inner wall, and the other is arranged on the outer side wall of the inner ring body 100, and the first drive module and the second drive module are arranged opposite to each other;

[0049] The first drive module includes a plurality of magnetic pieces 410, the plurality of magnetic pieces 410 are arranged around the axis of the inner ring body 100, and the polarities of the end faces of any two adjacent magnetic pieces 410 facing the second drive module are opposite;

[0050] The second drive module includes a plurality of conductive coils 420, the plurality of conductive coils 420 are arranged around the axis of the inner ring body 100, the plurality of conductive coils 420 are respectively electrically connected with the circuit board, and one end of the conductive coil 420 is opposite to the first drive module.

[0051] The outer side wall of the inner ring body 100 refers to the side wall of the inner ring body 100 located at the outermost side. The outer side wall of the inner ring body 100 and the inner side wall of the inner ring body 100 are two opposite side walls of the inner ring body 100.

[0052] It can be understood that the positions of the first driving module and the second driving module can be interchanged, and the positions can be set as required. For example, in some embodiments of the present application, the first driving module can be arranged on the first annular inner wall, and the second driving module can be arranged on the outer lateral wall of the inner ring body 100. For another example, in some other embodiments of the present application, the second driving module can be arranged on the first annular inner wall, and the first driving module can be arranged on the outer lateral wall of the inner ring body 100. Please refer to Figure 1 , in the following, the first driving module is arranged on the first annular inner wall, and the second driving module is arranged on the outer lateral wall of the inner ring body 100 as an example, the structure of the annular wearable device provided by the embodiments of the present application is further explained and described.

[0053] The magnetic member 410 can be various types of magnetic members 410, for example, can be a magnet block, an electromagnet, etc. Please refer to Figure 1 , among the plurality of magnetic members 410, the polarities of the end faces of any two adjacent magnetic members 410 facing the second driving module are opposite, which means that the south and north poles of the plurality of magnetic members 410 are alternately arranged along the axis of the inner ring body 100. The arrangement of the plurality of magnetic members 410 around the axis of the inner ring body 100 can mean that the plurality of magnetic members 410 are arranged along the circumferential direction of the first annular inner wall.

[0054] One end of the conductive coil 420 opposite to the first driving module can mean that the axis of the conductive coil 420 faces the first driving module, for example, in some embodiments of the present application, the extension direction of the axis of the conductive coil 420 can be the radial direction of the inner ring body 100. By making one end of the conductive coil 420 opposite to the first driving module, when the conductive coil 420 is energized, the end of the conductive coil 420 facing the first driving module is equivalent to the south pole or the north pole of a magnet. In order to facilitate the installation of the conductive coil 420, please refer to Figure 1 A plurality of windings 430 arranged in the circumferential direction can be arranged on the surface of the outer lateral wall of the inner ring body 100, and one coil can be correspondingly arranged on each winding 430, wherein the coil can be wound or sleeved on the corresponding winding 430 to realize the fixed connection between the coil and the outer lateral wall of the inner ring body 100 and realize the position fixation of the coil. The arrangement of the plurality of conductive coils 420 around the axis of the inner ring body 100 can mean that the plurality of conductive coils 420 are arranged along the circumferential direction of the outer lateral wall of the inner ring body 100.

[0055] It can be understood that the driving principle of the driving assembly 400 is the same as that of the brushless motor in the related art. Specifically, please refer to Figure 1, when the driving assembly 400 moves to Figure 1 When the position shown is Figure 1 The four conductive coils 420 are marked as conductive coil 1, conductive coil 2, conductive coil 3 and conductive coil 4 in the clockwise direction. Figure 4 The five magnetic members 410 are marked as magnetic member 1, magnetic member 2, magnetic member 3, magnetic member 4 and magnetic member 5 in the clockwise direction. Since each conductive coil 420 is facing the junction of two adjacent magnetic members 410, and the polarities of the end faces of the two adjacent magnetic members 410 facing the corresponding conductive coil 420 are opposite, when the polarity of the end of the conductive coil 1 facing the magnetic member 1 is opposite to that of the magnetic member 1, the polarity of the conductive coil 1 and the magnetic member 2 are the same. According to the principle that like charges repel and opposite charges attract, the conductive coil 1 will move toward the magnetic member 1. The inner ring body 100 rotates in the direction close to the magnetic part 1 and away from the magnetic part 2. At this time, the energizing direction of the conductive coil 2 can be opposite to that of the conductive coil 1, the energizing direction of the conductive coil 3 can be the same as that of the conductive coil 1, and the energizing direction of the conductive coil 4 can be opposite to that of the conductive coil 1. In this way, according to the same principle, the conductive coils 1, 2, 3 and 4 can all drive the inner ring body 100 to rotate counterclockwise through the corresponding windings 430, thereby realizing the relative rotation between the inner ring body 100 and the outer ring body 200. Accordingly, when it is necessary to control the inner ring body 100 to rotate clockwise relative to the outer ring body 200, it is sufficient to change the energizing directions of the conductive coils 1, 2, 3 and 4.

[0056] It is understood that the first and second drive modules can be arc-shaped or annular, and the larger the central angle of the first and second drive modules, the larger the travel range of the inner ring body 100. When the first and second drive modules are both annular, that is, the first drive module covers the entire circumference of the first annular inner wall, and the second drive module covers the entire circumference of the outer wall of the inner ring body 100, the travel range of the inner ring body 100 is maximized, and the inner ring body 100 can rotate a full circle relative to the outer ring body 200.

[0057] In this embodiment, the first drive module includes a plurality of magnetic parts 410, and the polarities of the end faces of any two adjacent magnetic parts 410 facing the second drive module are opposite. The second drive module includes a plurality of conductive coils 420. In this way, the circuit board only needs to control the power supply direction of the conductive coils 420 to control the forward or reverse rotation of the inner ring body 100 relative to the outer ring body 200, thereby driving the biosensor 300 to rotate to a position with strong signal quality.

[0058] Optionally, the first driving module and the second driving module are annular.

[0059] In this embodiment, by making the first driving module and the second driving module annular, i.e. the first driving module covers the entire circumferential direction of the first annular inner wall, and the second driving module covers the entire circumferential direction of the outer wall of the inner ring body 100, at this time, the stroke range of the inner ring body 100 is maximum, thereby facilitating the increase of the position adjustment range of the biosensor 300 to ensure that the biosensor 300 can be rotated to a position with strong signal quality.

[0060] Optionally, the annular wearable device is a smart ring, and the biosensor 300 comprises a light emitter 310 and at least one photodiode 320 (Photo-Diode, PD), and the light emitter 310 and the at least one photodiode 320 are electrically connected with the circuit board respectively; the light emitter 310 and the at least one photodiode 320 are fixedly connected with the inner ring body 100.

[0061] The light emitter 310 and the at least one photodiode 320 can be arranged along the inner wall of the inner ring body 100 around the axis of the inner ring body 100 in sequence, i.e. the light emitter 310 and the at least one photodiode 320 can be located on the same circumference, wherein the axis of the circumference coincides with the axis of the inner ring body 100. For example, please refer to Figure 6 When the number of photodiodes 320 is two, the two photodiodes 320 and the light emitter 310 are arranged along the inner wall of the inner ring body 100 around the axis of the inner ring body 100 in sequence, and the light emitter 310 is located between the two photodiodes 320.

[0062] It can be understood that the light emitting surface of the light emitter 310 and the light sensing surface of the photodiode 320 can face the annular opening 220, so that when the user wears the smart ring, the light emitter 310 can emit light to the user's finger, part of the light is absorbed by the skin tissue after penetrating the skin tissue, and part of the light is emitted and received by the photodiode 320. The photodiode 320 can detect the change in intensity of the reflected light and convert it into a digital signal, and send the digital signal to the circuit board. The circuit board can output relevant physiological indicators through algorithm calculation, and the physiological indicators include heart rate, blood oxygen, etc.

[0063] The above light emitting member can be various light emitters 310, for example, it can be a light emitting diode (Light-Emitting Diode, LED) lamp group, wherein the light emitting member can emit red light, infrared light, green light, etc. After the light emitted by the LED lamp group penetrates the skin tissue, part of the light is absorbed by the skin and part of the light is reflected.

[0064] In this embodiment, the biosensor 300 comprises a light emitter 310 and at least one photodiode 320, so that when the user wears the smart ring, the light emitter 310 can emit light to the user's finger, part of the light is absorbed after penetrating the skin tissue, and part of the light is emitted and received by the photodiode 320. The photodiode 320 can detect the change in intensity of the reflected light and convert it into a digital signal, and send the digital signal to the circuit board. The circuit board can output the relevant physiological indicators by algorithm calculation, thereby realizing the function of detecting biological indicators.

[0065] Please refer to Figure 6 , Figure 7 A flowchart of a control method provided by the embodiment is shown in the figure. The control method is applied to the circuit board of the annular wearable device described in the above embodiment. The method comprises the following steps:

[0066] In step 601, the driving assembly 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, so as to drive the biosensor 300 to rotate to the first position. The signal quality of the biosensor 300 in the first position is stronger than or equal to the signal quality of the biosensor 300 in the second position. The second position is the position of the biosensor 300 before the inner ring body 100 rotates.

[0067] Specifically, the signal quality of the biosensor 300 can be detected continuously during the process of controlling the biosensor 300 to rotate. When the biosensor 300 rotates to a position with good signal quality, this position can be determined as the first position, and the rotation of the inner ring body 100 is stopped, so as to drive the biosensor 300 to rotate to the first position.

[0068] In this embodiment, when the annular wearable device is in the wearing state, the circuit board can control the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 according to the signal quality of the biosensor 300. The biosensor 300 is fixedly connected to the inner ring body 100, so that the inner ring body 100 can drive the biosensor 300 to rotate synchronously during the rotation of the inner ring body 100. Therefore, the biosensor 300 can be rotated to a position with good signal quality, so as to improve the data acquisition effect of the biosensor 300, and further improve the accuracy of the physiological data output by the annular wearable device.

[0069] Optionally, the control of the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 to rotate the biosensor 300 to the first position comprises:

[0070] The control of the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 by a first angle value as a step size in a first direction for multiple times until the inner ring body 100 rotates a full circle, wherein the circuit board detects the signal quality of the biosensor 300 once for each rotation of the first angle value, and a plurality of signal quality values corresponding to the multiple rotations are obtained, wherein the first position is a position corresponding to a maximum signal quality value in the plurality of signal quality values, and the first direction is a clockwise direction or a counterclockwise direction.

In other embodiments of the present application, the first angle value can also be a relatively large angle value, for example, the first angle value can be in a range of 20°-50°.

[0073] The control of the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 by a first angle value as a step size in a first direction for multiple times until the inner ring body 100 rotates a full circle means that the driving assembly 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 in a first direction for multiple times, wherein each rotation is by a first angle value, and after each rotation of the first angle value, a signal quality is detected once, so that a plurality of signal quality values corresponding to the multiple rotations can be obtained.

[0074] Specifically, when the user wears the annular wearable device, the current position signal quality is detected and recorded, denoted as F0, and the inner ring body 100 is controlled to rotate by a first angle value in sequence, and the position signal quality is detected and recorded, denoted as F1, F2, F3, F4, …, Fn, until a full rotation is completed. The best signal quality Fmax and the corresponding inner ring body 100 angle Amax are found from F0 to Fn, and the inner ring body 100 is controlled to rotate to the Amax position, i.e., the best signal quality position.

[0075] Please refer to Figure 8 In some embodiments of the present application, the control method can include the following steps:

[0076] Step 701, control the inner ring body 100 to rotate by a first angle value in a first direction;

[0077] Step 702, record and cache the current position and signal quality;

[0078] Step 703, determine whether the inner ring body 100 has completed a full rotation, i.e., whether it has rotated a full circle;

[0079] If not, return to step 701;

[0080] If yes, execute step 704;

[0081] Step 704, determine the position with the best signal quality in the cache area as the first position;

[0082] Step 705, control the inner ring body 100 to rotate the biosensor 300 to the first position.

[0083] In this embodiment, the driving assembly 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 in a first direction multiple times, and multiple signal quality values corresponding to the multiple rotations are recorded, and the position corresponding to the maximum signal quality value among the multiple signal quality values is determined as the first position. Then, the biosensor 300 is controlled to rotate to the first position, thereby facilitating the determination of a position with better signal quality to which the biosensor 300 can rotate, so as to improve the signal quality of the biosensor 300.

[0084] Optionally, the control of the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 so that the inner ring body 100 drives the biosensor 300 to rotate to the first position includes:

[0085] controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 by a second angle value as a step in a direction in which the signal quality of the biosensor 300 is enhanced for at least two times until the signal quality of the biosensor 300 starts to weaken, wherein the circuit board detects the signal quality of the biosensor 300 once for each rotation of the inner ring body 100 by the second angle value, and at least two signal quality values corresponding to the at least two rotations are obtained, and the first position is a position corresponding to a maximum signal quality value among the at least two signal quality values;

[0086] controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, and stopping the rotation of the inner ring body 100 when the biosensor 300 is rotated to the first position.

[0087] In the direction in which the signal quality of the biosensor 300 is enhanced for at least two rotations until the signal quality of the biosensor 300 starts to weaken, the method further comprises: determining the direction in which the signal quality of the biosensor 300 is enhanced, which can specifically include: recording the signal quality of the biosensor 300 before the rotation, denoted as a first signal quality; controlling the inner ring body 100 to rotate by a second angle value in a first direction, and recording the signal quality of the biosensor 300 at this time, denoted as a second signal quality; if the second signal quality is greater than the first signal quality, it is determined that the first direction is the direction in which the signal quality is enhanced. If the second signal quality is less than the first signal quality, the inner ring body 100 is controlled to rotate by two second angle values in a second direction, and the signal quality of the biosensor 300 at this time is recorded, denoted as a third signal quality, and if the third signal quality is greater than the first signal quality, it is determined that the second direction is the direction in which the signal quality of the biosensor 300 is enhanced. The method further comprises: if the third signal quality is less than the first signal quality, the position before the rotation of the biosensor 300 is determined as the first position, i.e., the position corresponding to the first signal quality is determined as the first position. Among the first direction and the second direction, one is a clockwise direction and the other is a counterclockwise direction.

[0088] The value of the above-mentioned second angle value can be set as needed in some embodiments of the present application. The second angle value can be a relatively small angle value, for example, the second angle value can be an angle value less than 5°. In another embodiment of the present application, the second angle value can also be a relatively large angle value, for example, the value of the second angle value ranges between 20°-50°.

[0089] The control of the driving assembly 400 driving the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 in the direction of signal quality enhancement of the biosensor 300 until the signal quality of the biosensor 300 begins to weaken means that the driving assembly 400 drives the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 in the direction of signal quality enhancement of the biosensor 300 until the signal quality after rotation is lower than the signal quality after the last rotation. For example, when the number of rotations of the inner ring body 100 is k times, then during the 0 to (k-1) rotations, the signal quality before each rotation is less than or equal to the signal quality after rotation; the signal quality before the kth rotation is greater than the signal quality after rotation. At this time, it can be determined that the position after the (k-1) rotation is the position with the optimal signal quality in the current rotation process, and therefore, the position after the (k-1) rotation can be determined as the first position, and the k is an integer greater than 1.

[0090] Please refer to Figure 9 In some embodiments of the present application, the control method can include the following steps:

[0091] Step 801, determining the direction of signal quality enhancement;

[0092] Step 802, controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 in the direction of signal quality enhancement of the biosensor 300 by a second angle value;

[0093] Step 803, collecting the signal quality of the biosensor 300;

[0094] Step 804, determining whether the signal quality is less than the last collected signal quality;

[0095] If yes, step 805 is performed, and the driving assembly 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 in the direction of signal quality enhancement of the biosensor 300 by a second angle value, and the control of the inner ring body 100 to stop rotating is stopped;

[0096] If not, return to step 802 until the inner ring body 100 stops rotating.

[0097] In this embodiment, the inner ring body 100 is driven by the driving assembly 400 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 by a second angle value as a step size, and is rotated at least twice in the direction in which the signal quality of the biosensor 300 is enhanced until the signal quality of the biosensor 300 starts to weaken, and at least two signal quality values corresponding to the at least two rotations are recorded, and the position corresponding to the maximum signal quality value of the at least two signal quality values is determined as the first position, and then the biosensor 300 is controlled to rotate to the first position, thereby facilitating determination of a position to which the biosensor 300 can be rotated to have better signal quality, so as to improve the signal quality of the biosensor 300. Moreover, in the process of adjusting the biosensor 300 each time, the inner ring body 100 does not necessarily need to rotate a full circle, and thus the power consumption of the driving assembly 400 can be saved.

[0098] Optionally, the driving of the inner ring body 100 relative to the outer ring body 200 around the axis of the inner ring body 100 by the driving assembly 400 to rotate the biosensor 300 to the first position comprises:

[0099] In a case where it is detected that the ring-shaped wearable device is switched from the non-wearing state to the wearing state, the driving assembly 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, so as to rotate the biosensor 300 to the first position by the inner ring body 100; or,

[0100] In the case where the ring-shaped wearable device is in the wearing state, the driving assembly 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 every first time length, so as to rotate the biosensor 300 to the first position by the inner ring body 100.

[0101] Specifically, the switching of the ring-shaped wearable device from the non-wearing state to the wearing state can specifically mean that a user wears the ring-shaped wearable device. In some embodiments of the present application, since the ring-shaped wearable device after being worn by the user can not be in the position of the best signal quality in the process of wearing the ring-shaped wearable device, in a case where it is detected that the ring-shaped wearable device is switched from the non-wearing state to the wearing state, the driving assembly 400 can be controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, so as to rotate the biosensor 300 to the first position by the inner ring body 100, so as to ensure that the ring-shaped wearable device can be automatically adjusted to a position of better signal quality after the ring-shaped wearable device is worn by the user.

[0102] The first time length can be set as needed, for example, 5 minutes, 10 minutes, 30 minutes or 1 hour, etc. Specifically, since the ring-shaped wearable device may be rotated as a whole due to some reasons after being worn by the user, the position of the biological sensor 300 can be adjusted every first time length, so as to ensure that the biological sensor 300 is always in a position with relatively good signal quality.

[0103] In this embodiment, by controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 to make the inner ring body 100 drive the biological sensor 300 to rotate to the first position when it is detected that the ring-shaped wearable device is switched from the non-wearing state to the wearing state, it can be ensured that the ring-shaped wearable device can be automatically adjusted to a position with good signal quality after the user wears the ring-shaped wearable device. In addition, by controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 to make the inner ring body 100 drive the biological sensor 300 to rotate to the first position every first time length when the ring-shaped wearable device is in the wearing state, it can be ensured that the biological sensor 300 is always in a position with relatively good signal quality.
