[0045] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] With the popularity of smart wearable devices, their usage scenarios have become increasingly complex and varied. Generally, users operate smart wearable devices, such as smart watches, mainly by sliding the touch screen or rotating the crown. However, in special usage situations, such as when users are diving or wearing gloves in cold environments, it is difficult to slide the screen or operate the small crown, which brings troubles to users' use of smart wearable devices.

[0049] To this end, the present invention proposes a smart wearable device. It is understandable that the smart wearable device includes a smart watch, a smart bracelet, a smart armband, etc.

[0050] refer to Figure 1 and Figure 8 In one embodiment of the present invention, the smart wearable device includes:

[0051] Dial 10;

[0052] The watch strap 20, the dial 10 is disposed on the watch strap 20 and is rotatably connected to the watch strap 20, and a light-emitting component 12 is disposed on the side of the dial 10 facing the watch strap 20;

[0053] The light emitting component 12 is used to emit a first light signal to the surface of the watch strap 20, so that the first light signal is reflected by the watch strap 20 and then illuminates the dial 10;

[0054] The dial 10 is used to detect the optical signal parameters of the first optical signal irradiated on the dial 10, and determine its own rotation amount relative to the strap 20 according to the optical signal parameters, and perform corresponding control actions according to the rotation amount.

[0055] Optionally, the rotation amount includes the rotation angle and / or rotation direction of the dial 10 relative to the strap 20. The control action may directly include an upward slide action, a downward slide action, confirmation, cancellation, withdrawal, numerical value adjustment to a larger value, numerical value adjustment to a smaller value, and the like. The dial 10 may perform the corresponding control action mentioned above according to the rotation direction and / or rotation angle. Specifically, the above sliding is used as an example for explanation. When the user drags the dial 10 or drags the strap 20 to rotate the dial 10 relative to the strap 20 in a clockwise direction by 20 degrees, the dial 10 will perform an upward slide action to display the content of the previous screen, and vice versa. It is understandable that in actual applications, R&D personnel can preset the correspondence between the rotation amount and the control action in advance, or the user can set the correspondence between the rotation amount and the control action according to their own needs, so as to meet the different usage needs of the user.

[0056] Optionally, the light-emitting component 12 can be implemented by an LED lamp and an LED lamp driving circuit connected in series therewith. It is understandable that an electronic control component 15 for controlling the light-emitting component 12 can be provided in the dial 10. When the user needs to start the control function by driving the dial 10 to rotate relative to the strap 20, the user can manipulate the dial 10 to cause the electronic control component 15 to control the LED lamp driving circuit to start working to illuminate the light-emitting component 12. When the user does not need to start the control function by driving the dial 10 to rotate relative to the strap 20, the user can also manipulate the dial 10 to cause the electronic control component 15 to control the LED lamp driving circuit to start working or stop working, thereby effectively reducing the power consumption of the smart wearable device and improving the battery life of the smart wearable device. At the same time, if the user accidentally touches the dial 10 and causes the dial 10 to rotate relative to the strap 20, the dial 10 will not perform the corresponding control action, effectively improving the user's experience and convenience in using the smart wearable device.

[0057] Optionally, the strap 20 includes: a first strap 21 and a second strap 22, the first strap 21 is mounted on the second strap 22 and is rotatably connected to the second strap 22; wherein the dial 10 is fixedly connected to the first strap 21; when the first strap 21 rotates relative to the second strap 22, the first strap 21 drives the dial 10 to rotate relative to the second strap 22; the light-emitting component 12 is used to emit a first light signal to the surface of the second strap 22, so that the first light signal is reflected by the second strap 22 and illuminates the dial 10.

[0058] In this embodiment, one of the first strap 21 and the second strap 22 is provided with a first card slot 211 along its length direction, and the other is provided with a first card member 221 along its length direction; when the first strap 21 is sleeved on the second strap 22, the first card member 221 is slidably connected to the first card slot 211. It can be understood that the number of first card slots 211 and corresponding first card members 221 can be multiple. Optionally, the first card slot 211 can be provided on one of the side of the first strap 21 away from the contact with the dial 10 and the side of the second strap 22 away from the contact with the user's skin, and the first card member 221 can be provided on the other, or reference can be made to FIG. Figure 2 As shown, for example, a second watchband 22 is provided with a first latch 221, and a first watchband 21 is provided with a latch slot. The second watchband 22 is provided with a mounting slot, with first latches 221 disposed in both side walls. First latch slots 211 are disposed on opposite sides of the first watchband 21. When the first watchband 21 is installed in the second watchband 22, the first latches 221 slide into the first latch slots 211. In this way, in actual use, the user can drag the first watchband 21 to rotate the dial 10 relative to the second watchband 22. The mounting slot also acts as a limiter to prevent the first watchband 21 from detaching from the second watchband 22 when being pulled by the user.

[0059] In another embodiment, no rotating part may be provided between the first strap 21 and the second strap 22 , and the user may directly drag the first strap 21 to rotate the first strap 21 relative to the second strap 2230 .

[0060] In one embodiment of the present invention, reference Figure 2-4 The second strap 22 is provided with a sensing portion 30, and the sensing portion 30 extends along the length direction of the second strap 22;

[0061] A light detection component 13 is provided on the dial 10 at a position corresponding to the sensing portion 30 , and an electric control component 15 electrically connected to the light detection component 13 is provided inside the dial 10 ;

[0062] The light emitting component 12 is used to emit a first light signal to the sensing portion 30 on the second strap 22, so that the first light signal is reflected by the sensing portion 30 and then illuminates the light detecting component 13;

[0063] The light detection component 13 is used to detect light signal parameters of the first light signal irradiated on the light detection component 13 and output a corresponding light detection signal;

[0064] The electronic control component 15 is used to determine the rotation amount of the dial 10 relative to the strap 20 based on the light detection signal, and perform corresponding control actions based on the rotation amount.

[0065] In this embodiment, a light-transmitting opening may be provided on the upper housing of the dial 10 at a position corresponding to the sensing portion 30, so that the first light signal reflected by the sensing portion 30 can pass through the light-transmitting opening and illuminate the light detection assembly 13. Optionally, a light-transmitting member 11 may be provided in the light-transmitting opening and closely contact the light detection assembly 13. The light-transmitting member 11 may be implemented using light-guiding silicone, a light-guiding column, glass, or the like. This allows the first light signal reflected by the sensing portion 30 to pass through the light-transmitting member 11 and illuminate the light detection assembly 13, thereby enabling the first light signal reflected by the sensing portion 30 to accurately illuminate the light detection assembly 13, thereby effectively improving the accuracy of the light detection assembly 13 in detecting the light signal parameters.

[0066] In this embodiment, the electronic control component 15 can be implemented by a main controller, such as an MCU, a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a SOC (System On Chip), etc.

[0067] Optionally, in one embodiment, the sensing portion 30 is disposed at the position of the second strap 22 corresponding to the bottom of the dial 10, that is, when the user drags the first strap 21 to drive the dial 10 to rotate relative to the second strap 22, the bottom of the entire dial 10 is pressed against the sensing portion 30, and the light detection component 13 corresponds to the position of the sensing portion 30. The light-emitting component 12 can be disposed at the bottom of the dial 10 to directly emit a first light signal to the second strap 22. The light-emitting component 12 can also be disposed inside the dial 10 corresponding to the position of the light-transmitting port on the dial 10 to emit a first light signal to the second strap 22 through the light-transmitting port.

[0068] Optionally, in another embodiment, side walls may be provided on both sides of the second watchband 22, and the dial 10 may be provided in an installation position formed by the side walls of the second watchband 22 and the side facing away from the user's skin contact. The second watchband 22 is provided with a sensing portion 30. Correspondingly, the light detection component 13 within the dial 10 is also provided on the side of the dial 10, so that the first light signal emitted by the light-emitting component 12 is reflected by the sensing portion 30 on the side wall of the second watchband 22 and can be illuminated by the light detection component 13.

[0069] Optionally, the light detection component 13 can be implemented using a photodiode, a color temperature detection sensor, etc. It is understandable that the light signal parameters may include light intensity, color temperature, etc. Specifically, taking color temperature as an example, the sensing part 30 can be composed of multiple groups of three reflective parts 31 of different colors, and arranged in sequence around the strap 20. During the rotation of the dial 10 relative to the strap 20, the electronic control component 15 can confirm the number and direction of the sensing parts 30 of the current dial 10 based on the feedback from the color temperature detection sensor, and then obtain the current rotation amount of the dial 10 relative to the strap 20. It is understandable that the light-emitting component 12 and the light detection component 13 can be integrated in the same chip.

[0070] Thus, through the above arrangement, the dial 10 can detect the amount of rotation relative to the strap 20 and perform corresponding control actions based on the amount of rotation. This allows the user to control the smart wearable device by dragging the dial 10 relative to the strap 20, thereby improving the user's convenience in using the smart wearable device.

[0071] It is understandable that, in this embodiment, a limit slot may be further provided on the watch strap 20, and a limit clip rotatably connected to the watch dial 10 may be further provided on the watch dial 10. When the user does not need to drag the watch dial 10 to rotate relative to the watch strap 20, the user may first rotate the watch dial 10 to a corresponding position and move the limit clip to the second position so that it fits exactly into the limit slot on the watch strap 20, thereby preventing the watch dial 10 from rotating relative to the watch strap 20. When the user wants to drag the watch dial 10 to rotate relative to the watch strap 20, the user may move the limit clip to the first position to disengage the second slot, thereby allowing the user to drag the watch dial 10 to rotate relative to the watch strap 20 again, thereby improving user convenience.

[0072] The present invention discloses a smart wearable device, which includes a dial 10 and a strap 20. The dial 10 is arranged on the strap 20 and is rotatably connected to the strap 20. A light-emitting component 12 is provided on the side of the dial 10 facing the strap 20. The light-emitting component 12 is used to emit a first light signal to the surface of the strap 20, so that the first light signal is reflected by the strap 20 and irradiated on the dial 10. The dial 10 is used to detect the light signal parameters of the first light signal irradiated on the dial 10, and determine its own rotation amount relative to the strap 20 according to the light signal parameters, and perform corresponding control actions according to the rotation amount. In this way, in actual application, if the user's current situation is not convenient for sliding the screen or triggering the screen or rotating the smaller crown, the corresponding control of the smart wearable device can be achieved by driving the dial 10 to rotate relative to the strap 20, effectively improving the convenience of the user in using the smart wearable device.

[0073] In one embodiment of the present invention, the sensing portion 30 includes a plurality of reflecting portions 31 ; the plurality of reflecting portions 31 have at least two light reflectances;

[0074] The light detection component 13 is used to detect the light intensity of the first light signal irradiated on the light detection component 13 and output a corresponding light intensity detection signal;

[0075] The electronic control component 15 is used to determine the rotation amount of the dial 10 relative to the strap 20 according to the light intensity detection signal, and perform corresponding control actions according to the rotation amount;

[0076] The plurality of reflecting portions 31 are continuously arranged along the extending direction of the second strap 22 ; or the plurality of reflecting portions 31 are spaced apart along the extending direction of the second strap 22 .

[0077] In this embodiment, the light detection component 13 can be implemented using a light intensity detection component, such as a photodiode or a light intensity detection chip. The reflective portion 31 can be a pattern engraved on the surface of the second strap 22. Different patterns can give the reflective portion 31 different light reflectivities. For example, if the reflective portion 31 currently has a light reflectivity of 50%, when a first light signal is irradiated by the reflective portion 31, only half of the first light signal will be reflected by the reflective portion 31 and directed to the light detection component 13.

[0078] Optionally, the light reflectivity of the multiple reflective parts 31 may be different, refer to Figure 3 , for example, the second strap 22 is provided with 8 reflective parts 31, and the reflectivities of the 8 reflective parts 31 are A, B, C, D, E, F, G and H respectively, and the reflectivity of each reflective part 31 is different. Figure 3 The diagram shown in FIG is a schematic diagram of the structure when the second strap 22 is laid flat. During the research and development period, the researchers can conduct multiple experiments to obtain the light intensity value collected by the light intensity detection component when the first light signal emitted by the light emitting component 12 passes through different reflective parts 31 and illuminates the light intensity detection component, and form a reflective part 31-light intensity mapping table based on the above content. It is understandable that the length of each reflective part 31 on the strap 20 can be the same or different. In this embodiment, the length of the reflective part 31 is consistent as an example, that is, Figure 3 In the illustrated embodiment, each time the dial 10 passes through a reflective portion 31, it is equivalent to a 45-degree rotation relative to the second strap 22. When a user desires to execute a control action by rotating the strap 20 on the second strap 22, the electronic control component 15 can determine the emitting portion currently illuminated by the light-emitting component 12, i.e., the position of the dial 10, based on the current light intensity detection signal. This allows the electronic control component 15 to determine the reflective portion 31 currently passed by the dial 10 during the process of the user rotating the strap 20 on the second strap 22, and further determine the direction of the rotation angle of the dial 10 relative to the strap 20. Based on this direction of the rotation angle, the electronic control component 15 can then execute a corresponding control action.

[0079] For example, the current control action is that every time the dial 10 rotates counterclockwise relative to the second strap 22 and every time it rotates 45 degrees (from the reflective part 31 with a reflectivity of A to the reflective part 31 with a reflectivity of H), the brightness of the display interface is reduced by 10%; every time the dial 10 rotates clockwise relative to the second strap 22 (from the reflective part 31 with a reflectivity of H to the reflective part 31 with a reflectivity of A) and every time it rotates 45 degrees, the brightness of the display interface is increased by 10%. Then, when the user just turns on the above function, the electronic control component 15 confirms that the current light-emitting component 12 is irradiating the reflective part 31 with a reflectivity of C based on the light intensity detection signal. When the user pulls the first strap 21 to control the dial 10 to rotate clockwise relative to the second strap 22, the electronic control component 15 will confirm that the current dial 10 has passed through the reflective part 31 with a reflectivity of B, the reflective part 31 with a reflectivity of A, and the reflective part 31 with a reflectivity of H based on the light intensity detection signal and the above mapping table, and finally stops at the reflective part 31 with a reflectivity of G, then confirms that the dial 10 has rotated 135 degrees clockwise relative to the second strap 22 and controls the display brightness to increase by 30%; or, during the above rotation process, the electronic control component 15 will increase the display brightness by 10% every time it confirms that the dial 10 passes through a reflective part 31 in the clockwise direction, that is, every time it rotates 45 degrees in the clockwise direction, to provide customers with real-time feedback and improve their user experience.

[0080] Alternatively, in another embodiment, the plurality of reflective portions 31 may form a group of reflective portions 31, so that a plurality of groups of the same reflective portions 31 are repeatedly provided along the extending direction of the second strap 22. Figure 4 ,by Figure 4 The embodiment shown is used as an example for explanation. Figure 4 Each reflective portion 31 group shown in is composed of a reflective portion 31 with a reflectivity of A, a reflective portion 31 with a reflectivity of B, and a reflective portion 31 with a reflectivity of C, which are arranged in sequence. The angle corresponding to each reflective portion 31 is 40°. Similarly, in the process of the actual user dragging the first strap 21 to drive the dial 10 to rotate, the electronic control component 15 can confirm the current rotation direction and angle of the dial 10 according to the same embodiment process as above, and perform corresponding control actions according to the rotation angle and direction. In this way, not only can the rotation angle and direction of the dial 10 relative to the strap 20 be detected by light intensity detection, but the types of reflective portions 31 that need to be engraved can also be reduced, thereby reducing production costs and improving production efficiency. In addition, since the reflective portions 31 in each reflective group have the same reflectivity, in actual design, compared to setting multiple reflective portions 31 with different reflectivities on the dial 10 (for example Figure 3 As shown), by setting the reflection group, more reflection parts 31 can be set on the dial 10, thereby further improving the accuracy of detecting the angle of rotation of the dial 10 relative to the strap 20.

[0081] refer to Figure 5 and Figure 6 In one embodiment of the present invention, the sensing portion 30 includes a plurality of reflecting portions 31 ; the plurality of reflecting portions 31 have at least two colors;

[0082] The light detection component 13 is used to detect the color temperature of the first light signal irradiated on the light detection component 13 and output a corresponding color temperature detection signal;

[0083] The electronic control component 15 is used to determine the rotation amount of the dial 10 relative to the strap 20 according to the color temperature detection signal, and perform corresponding control actions according to the rotation amount.

[0084] The plurality of reflecting portions 31 are continuously arranged along the extending direction of the second strap 22 ; or the plurality of reflecting portions 31 are spaced apart along the extending direction of the second strap 22 .

[0085] In this embodiment, the light detection component 13 can be implemented by a color temperature detection component, such as a color temperature detection sensor. Each reflective portion 31 can be coated with a color of pigment, or a reflective film of a different color can be provided on the surface of the reflective portion 31. When the first light signal is irradiated on the reflective portion 31, the reflective portion 31 reflects a light signal of a corresponding color to the color temperature detection component according to the color of the first light signal. For example, if the color of the current reflective portion 31 is red and the first light signal is white light, then when the first light signal is irradiated on the reflective portion 31, the color temperature detection component can detect that the color of the current reflective portion 31 is red. It is understandable that during the research and development period, the R&D personnel will conduct multiple experiments to obtain the color temperature value detected by the color temperature detection component when the first light signal is irradiated on each reflective portion 31, and form a corresponding color temperature-reflective portion 31 mapping table.

[0086] Optionally, the colors of the lights on the multiple reflective parts 31 may be different, see Figure 6 , take the second strap 22 as an example with eight reflective parts 31, the colors of the eight reflective parts 31 are red, orange, yellow, green, blue, indigo, purple, white and black. Figure 6 The diagram in FIG. 2 is a schematic diagram of the structure of the second strap 22 when it is laid flat. It is understood that the length of each reflective portion 31 on the strap 20 can be the same or different. In this embodiment, the length of the reflective portion 31 is the same as an example. Figure 3In the illustrated embodiment, each time the dial 10 passes through a reflective portion 31, it is equivalent to a 45-degree rotation relative to the second strap 22. When a user desires to execute a control action by rotating the strap 20 on the second strap 22, the electronic control component 15 can determine the emitting portion currently illuminated by the light-emitting component 12, i.e., the position of the dial 10, based on the current color temperature detection signal. This allows the electronic control component 15 to determine the reflective portion 31 currently passed by the dial 10 during the process of the user rotating the strap 20 on the second strap 22, and further determine the direction of the rotation angle of the dial 10 relative to the strap 20. Based on this direction of the rotation angle, the electronic control component 15 can then execute the corresponding control action.

[0087] For example, the current control action is that every time the dial 10 rotates counterclockwise relative to the second strap 22 and every time it rotates 45 degrees (from the red reflective part 31 to the black reflective part 31), the display interface brightness is reduced by 10%; every time the dial 10 rotates clockwise relative to the second strap 22 (from the black reflective part 31 to the red reflective part 31) and every time it rotates 45 degrees, the display interface brightness is increased by 10%. Then, when the user just turns on the above function, the electronic control component 15 confirms that the current light-emitting component 12 is irradiating the reflective portion 31 with color C based on the color temperature detection signal. When the user pulls the first strap 21 to control the dial 10 to rotate clockwise relative to the second strap 22, the electronic control component 15 will confirm that the current dial 10 has passed through the reflective portion 31 with orange color, the reflective portion 31 with red color, and the reflective portion 31 with black color based on the color temperature detection signal and the above mapping table, and finally stops at the reflective portion 31 with white color, then confirms that the dial 10 has rotated 135 degrees clockwise relative to the second strap 22 and controls the display brightness to increase by 30%; or, during the above rotation process, the electronic control component 15 will increase the display brightness by 10% every time it confirms that the dial 10 passes through a reflective portion 31 in the clockwise direction, that is, every time it rotates 45 degrees in the clockwise direction, so as to provide customers with real-time feedback and improve their user experience.

[0088] Alternatively, in another embodiment, the plurality of reflective portions 31 may form a group of reflective portions 31, so that a plurality of groups of the same reflective portions 31 are repeatedly provided along the extending direction of the second strap 22. Figure 5 ,by Figure 5 The embodiment shown is used as an example for explanation. Figure 5Each reflective portion 31 group shown in the figure is composed of a reflective portion 31 of red, a reflective portion 31 of green and a reflective portion 31 of blue arranged in sequence. The angle corresponding to each reflective portion 31 is 40°. Similarly, in the process of the actual user dragging the first strap 21 to drive the dial 10 to rotate, the electronic control component 15 can confirm the current rotation direction and angle of the dial 10 according to the same embodiment process as above, and perform corresponding control actions according to the rotation angle and direction. Through the above arrangement, not only can the rotation angle and direction of the dial 10 relative to the strap 20 be detected by color temperature detection, but also the types of colors that need to be coated on the reflective portion 31 can be reduced, thereby reducing production costs and improving production efficiency. In addition, since the colors of the reflective portions 31 in each reflective group are the same, in actual design, compared with setting a plurality of reflective portions 31 of different colors on the dial 10 (for example Figure 3 As shown), by setting the reflection group, more reflection parts 31 can be set on the dial 10, thereby further improving the accuracy of detecting the angle of rotation of the dial 10 relative to the strap 20.

[0089] refer to Figure 3-6 There are multiple sensing parts 30, multiple light-transmitting elements 11, and multiple light-detecting components 13; the number of light-detecting components 13, the number of light-transmitting elements 11, and the number of sensing parts 30 are the same.

[0090] Optionally, in one embodiment, the type of each sensing portion 30 is the same, and the type of each light detection component 13 is also the same, for example Figure 5 In the embodiment, the two sensing portions 30 on the second strap 22 are each composed of a plurality of color blocks consisting of red, green and blue color blocks.

[0091] Alternatively, in another embodiment, each sensing portion 30 may be of at least two types, and correspondingly, the light detection components 13 may also be of at least two types. For example, currently, two sensing portions 30 are provided on the second strap 22, one sensing portion 30 comprising a reflective portion 31 having at least two reflectivities, and the other sensing portion 30 comprising a reflective portion 31 having at least two colors. Correspondingly, there are multiple light detection components 13, one being a light intensity detection component and the other being a color temperature detection component.

[0092] It can be understood that, in combination with the contents of the above embodiments, in this embodiment, the electronic control component 15 is also used to determine its own rotation amount relative to the strap 20 based on the multiple light detection signals output by the multiple light detection components 13, and perform corresponding control actions based on the rotation amount.

[0093] Optionally, in one embodiment, the electronic control component 15 averages the at least two rotation quantities obtained to obtain an average rotation angle, and performs the above-mentioned control action according to the content of the above embodiment based on the average rotation angle. In this way, in actual application, if one or more of the light detection components 13 fails and / or the light emitting component 12 fails and / or the reflective portion 31 on the sensing portion 30 is damaged, causing the electronic control component 15 to detect that the rotation angle value of the dial 10 relative to one or more of the sensing portions 30 is 0 or a very small value, then when the dial 10 rotates relative to the second strap 22, the electronic control component 15 can still calculate a certain rotation amount based on other normal rotation quantities through an average calculation method, thereby ensuring that when some components and / or the sensing portion 30 on the smart wearable device are damaged, the user can still control the smart wearable device by dragging the dial 10 on the strap 20, thereby improving the convenience of user use. In addition, it can be understood that in another embodiment, the electronic control component 15 determines that the rotation angle in one rotation amount is 0 or close to 0, while the rotation angle in other rotation amounts is not 0, then the rotation angle of 0 in the rotation amount can be directly confirmed as an erroneous rotation amount, and corresponding actions can be performed according to other normal rotation amounts.

[0094] Optionally, in another embodiment, the electronic control component 15 will compare the at least two rotation quantities obtained. If the difference between the rotation angles of all the current rotation quantities is less than the preset angle difference and the rotation directions are consistent, then the electronic control component 15 can confirm that the light detection component 13 and / or the light emitting component 12 and / or the reflective portion 31 on the sensing portion 30 are normal, and perform corresponding action control according to the multiple rotation quantities, for example, perform corresponding control actions according to the average value of the rotation angles. If the difference between the rotation angles of all the current rotation quantities is greater than the preset angle difference and / or the rotation directions are inconsistent, then the electronic control component 15 can confirm that the rotation quantity detection is abnormal, and will not perform any control action, and will prompt the user of the current rotation detection failure through a prompt component, such as a touch screen. In this way, in actual applications, it can effectively prevent the control action from being falsely triggered due to a failure of the detection component used to detect the rotation quantity, thereby ensuring the user's experience of using the smart wearable device.

[0095] In one embodiment of the present invention, reference Figure 7 , the dial 10 and the strap 20 are snap-connected;

[0096] One of the dial 10 and the strap 20 is provided with a second card slot 23 along its length, and the other is provided with a second card member 14 along its length.

[0097] When the watch dial 10 is engaged with the watch band 20 , the second engaging member 14 is slidably connected to the second engaging slot 23 .

[0098] In this embodiment, the second latch 14 can be disposed at the bottom of the watch face 10, and the second latch slot 23 on the watch band 20 can be disposed on the side of the watch band 20. When the user drags the watch face 10, the second latch 14 slides within the second latch slot 23, thereby enabling the watch face 10 to move relative to the watch band 20. The number of second latches 14 can be one or more, so as to slide correspondingly within the plurality of second latch slots 23 on the watch band 2010 to ensure the stability of the rotation of the watch face 1020 when the watch face 10 is dragged relative to the watch band 20. Furthermore, the second latch 14 can also be disposed on the side of the watch face 1020, with second latch slots 23 disposed on both sides of the watch band 2010 for receiving the second latch 14.

[0099] It is understandable that the sensing portion 30 can also be provided on the strap 20. In this embodiment, when the user drags the dial 10 to rotate relative to the strap 20, the electronic control component 15 in the dial 10 can also determine the current rotation amount of the dial 10 relative to the strap 20 based on the light detection signal output by the light detection component 13, and perform corresponding actions according to the rotation amount. The specific process can be referred to the process in the above embodiment and will not be repeated here.

[0100] The above contents are only optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
