[0043] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] 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 positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0046] With the increasing popularity of smart wearable devices, the usage scenarios are becoming more complex and varied. Generally, users control smart wearable devices, such as smartwatches, mainly by swiping the touchscreen 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 swipe the screen or operate the small crown, which brings inconvenience to users using smart wearable devices.

[0047] Therefore, this invention proposes a smart wearable device. It is understood that smart wearable devices include smartwatches, smart bracelets, smart armbands, etc.

[0048] refer to Figure 1 In one embodiment of the present invention, the smart wearable device includes:

[0049] Dial 10;

[0050] Watch strap 00, watch face 10 is disposed on watch strap 00 and rotatably connected to watch strap 00;

[0051] The dial 10 is used to detect its rotation relative to the strap 00 and to perform corresponding control actions based on the rotation amount.

[0052] In this embodiment, the amount of rotation includes the rotation angle and / or rotation direction of the dial 10 relative to the strap 00.

[0053] Optionally, the control actions can directly include upward sliding, downward sliding, confirming, canceling, reverting, increasing the value, decreasing the value, etc. The dial 10 is equipped with a corresponding electronic control component 50, which can execute the above-mentioned control actions according to the rotation direction and / or rotation angle. Specifically, taking the upward sliding as an example, when the user drags the dial 10 or the watch strap 00 so that the dial 10 rotates 20 degrees clockwise relative to the watch strap 00, the dial 10 will perform an upward sliding action to display the content of the previous screen, and vice versa.

[0054] Understandably, in practical applications, R&D personnel can pre-set the correspondence between rotation amount and control action, or users can set the correspondence between rotation amount and control action according to their own needs, thereby meeting different user requirements.

[0055] Optionally, in one embodiment, the watch strap 00 may be provided with at least one guide rail, and the dial 10 may be disposed on at least one guide rail of the watch strap 00 and rotate relative to the watch strap 00 along at least one guide rail. It is understood that the dial 10 is provided with corresponding transmission components and detection components corresponding to the guide rail. The detection components can detect the movement distance of the transmission components on the watch strap 00, thereby enabling the dial 10 to determine its specific rotation angle based on the movement distance-rotation multi-angle formula measured and preset by researchers during the development phase. In this way, the dial 00 can perform the aforementioned control actions according to its own rotation angle and rotation direction relative to the watch strap.

[0056] Optionally, in another embodiment, the watch strap 00 includes a first watch strap 20 and a second watch strap 30, wherein the first watch strap 20 is sleeved on the second watch strap 30 and rotatably connected to the second watch strap 30;

[0057] The dial 10 is fixedly connected to the first strap 20; when the first strap 20 rotates relative to the second strap 30, the first strap 20 drives the dial 10 to rotate relative to the second strap 30.

[0058] The dial 10 is used to detect its own rotation relative to the second strap 30 and to perform corresponding control actions based on the rotation amount.

[0059] In this embodiment, the first watch strap 20 is directly fitted onto the second watch strap 30. A rotating component, such as a bearing, can be provided between the first watch strap 20 and the second watch strap 30; alternatively, no rotating component can be provided, and the user can directly drag the first watch strap 20 to rotate it relative to the second watch strap 30. It is understood that the second watch strap 30 can be provided with limiting components to fix the position of the first watch strap 20 and prevent it from detaching from the second watch strap 30 during user pulling. For example, limiting components are provided on both sides of the second watch strap 30, and the first watch strap 20 is placed within the limiting groove formed by the two limiting components and one side of the second watch strap 30.

[0060] Specifically, refer to Figure 2 In one embodiment, a sensing part 40 is provided on the second watch strap 30, and the sensing part 40 extends along the length direction of the second watch strap 30.

[0061] The dial 10 includes a transmission component 11 and an electronic control component 50. The transmission component 11 is disposed on the sensing part 40. When the first watch strap 20 drives the dial 10 to rotate relative to the second watch strap 30, the transmission component 11 of the dial 10 moves on the sensing part 40.

[0062] The electronic control component 50 is used to detect the amount of movement of the transmission component 11 on the sensing part 40 to determine the amount of rotation of the dial 10 relative to the second strap 30, and to perform corresponding control actions based on the amount of rotation.

[0063] In this embodiment, the sensing unit 40 is disposed on the side of the second strap 30 facing the dial 10. Optionally, in one embodiment, the sensing unit 40 is disposed at the position of the second strap 30 corresponding to the bottom of the dial 10, that is, when the user drags the first strap 20 to rotate the dial 10 relative to the second strap 30, the entire dial 10 presses against the sensing unit 40 or the sensing unit 40 passes through the bottom of the dial 10. Optionally, in another embodiment, the sensing unit 40 can be disposed at the position of the second strap 30 corresponding to the side of the dial 10, that is, when the user drags the first strap 20 to rotate the dial 10 relative to the second strap 30, the sensing unit 40 is always on the side of the strap 10.

[0064] Optionally, in one embodiment, when the transmission component 11 passes the sensing part 40, the sensing part 40 can drive the transmission component 11 to rotate, move, or actuate. In other words, during the movement of the dial 10 relative to the second strap 30, the transmission component 11 will continuously or periodically contact the sensing part 40 and rotate, move, or actuate under the drive of the sensing part 40. Specifically, the sensing part 40 can be implemented using a rack, which is arranged in a circle around the second strap 30. The transmission component 11 can be implemented using a gear, where the gear moves on the rack when the user drags the first strap 20 to rotate the dial 10 relative to the second strap 30. The electronic control component 50 can detect the distance and direction of movement of the gear on the rack, thereby obtaining the current amount of rotation of the dial 10 relative to the second strap 30.

[0065] Optionally, in another embodiment, the sensing unit 40 may not contact the transmission component 11. In other words, during the movement of the dial 10 relative to the second strap 30, the sensing unit 40 will not drive the transmission component 11 to move, and the transmission component 11 will not contact the sensing unit 40, or if the transmission component 11 contacts the sensing unit 40, the transmission component 11 will not move. Specifically, the sensing unit 40 may be composed of multiple sets of three different colored blocks, arranged sequentially around the second strap 30. The transmission component 11 is directly implemented using a color temperature detection sensor and an LED light. During the rotation of the dial 10 relative to the second strap 30, the electronic control component 50 can determine the number and direction of the sensing units 40 passed by the current transmission component 11 based on the feedback from the color temperature detection sensor, thereby obtaining the current rotation amount of the dial 10 relative to the second strap 30.

[0066] Thus, through the above settings, the watch face 10 can detect its rotation relative to the second strap 30 and execute corresponding control actions based on the rotation amount. This allows users to control the smart wearable device by pulling the first strap 20 to rotate the watch face 10 relative to the second strap 30, improving the convenience of using the smart wearable device.

[0067] It is understood that, in this embodiment, the dial 10 may also be provided with limiting components, such as limiting slots or limiting rods, so as to fix the dial 10 on the strap 00 when the user does not need to drag the dial 10 to rotate relative to the strap 00, so as to prevent the dial 10 from rotating relative to the strap 00 under large external forces and affecting the user's daily use.

[0068] Furthermore, it is understandable that when the user does not need the function of rotating the watch band 00 relative to the watch face 10 to perform corresponding control actions, this function can be manually turned off by controlling the smart wearable device. Thus, if the user accidentally touches the watch face 10, causing it to rotate relative to the watch band 00, the watch face 10 will not perform any corresponding control actions, effectively improving the user experience and convenience of using the smart wearable device.

[0069] This invention discloses a smart wearable device, comprising a watch face 10 and a watch strap 00. The watch face 10 is disposed on and rotatably connected to the watch strap 00. The watch face 10 detects its rotation relative to the watch strap 00 and executes corresponding control actions based on the rotation amount. Thus, in practical applications, if it is inconvenient for the user to slide the screen, trigger the screen, or rotate the crown slightly, they can control the smart wearable device by pulling the watch face 10 relative to the watch strap 00, effectively improving the convenience of using the smart wearable device.

[0070] In one embodiment of the present invention, reference is made to... Figure 5 The electronic control component 50 includes a main control component 51, a resistance detection component 52, and a potentiometer 53. The potentiometer 53 is electrically connected to the resistance detection component 52, and the main control component 51 is electrically connected to the resistance detection component 52.

[0071] Among them, potentiometer 53 has a rotating shaft, which is fixedly connected to transmission assembly 11;

[0072] When the transmission assembly 11 moves along the sensing part 40, the sensing part 40 drives the transmission assembly 11 to rotate the rotating shaft to change the resistance value of the potentiometer 53.

[0073] The resistance detection component 52 is used to detect the resistance value of the potentiometer 53 and output a corresponding resistance detection signal;

[0074] The main control component 51 is used to determine the amount of rotation of the dial 10 relative to the second strap 30 based on the resistance detection signal, and to execute corresponding control actions based on the amount of rotation.

[0075] It is understood that potentiometer 53 can be a digital potentiometer 53 or an analog potentiometer 53. When potentiometer 53 is rotated, its resistance value will increase or decrease. In this embodiment, the main control component 51 can be implemented using a main controller, such as an MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), or SOC (System on Chip). The resistance detection component 52 can be implemented using a current detection circuit and a power supply terminal. The output terminal of potentiometer 53, the power supply terminal, and the current detection circuit are connected in series. The main control component 51 can calculate the current resistance value of potentiometer 53 based on the current flowing through potentiometer 53 detected by the current detection circuit and the known power supply voltage connected to the power supply terminal. The current detection circuit can be implemented using a current sensing resistor. The main control component 51 can detect the voltage across the current sensing resistor and calculate the current flowing through it, i.e., the current flowing through potentiometer 53.

[0076] Specifically, as the dial 10 moves relative to the second strap 30, when it passes the sensing unit 40, the sensing unit 40 drives the transmission component 11 to operate. When the transmission component 11 operates, it in turn drives the rotating shaft of the potentiometer 53 to rotate, thereby changing the resistance value of the potentiometer 53. The main control component 51 can determine the current rotation amount of the dial 10 relative to the second strap 30 based on the change in the resistance value of the potentiometer 53 detected by the resistance detection component 52 and a preset resistance change-angle change relationship. For example, if the resistance value increases by 10Ω, the dial 10 rotates 20 degrees clockwise relative to the second strap 30; if it decreases by 10Ω, the dial 10 rotates 20 degrees counterclockwise relative to the second strap 30. If the user drags the first strap 20 to rotate the dial 10, and the main control component 51 confirms that the resistance value of the potentiometer 53 has increased by 20Ω, it can confirm that the dial 10 has rotated 40 degrees clockwise relative to the second strap 30. Understandably, the main control component 51 initiates the resistance change only when the resistance of potentiometer 53 begins to change. If the resistance of potentiometer 53 remains unchanged within a preset time period, the main control component 51 will recalculate the resistance change the next time the resistance of potentiometer 53 changes. The preset resistance change-angle change relationship and the preset time period are both set by the R&D personnel during the R&D process based on actual design requirements.

[0077] Alternatively, in another embodiment, reference is made to... Figure 6 The electronic control component 50 includes a main control component 51 and an encoder 54, with the encoder 54 electrically connected to the main control component 51.

[0078] The encoder 54 has a rotating shaft, which is fixedly connected to the transmission assembly 11.

[0079] When the transmission assembly 11 moves along the sensing part 40, the sensing part 40 drives the transmission assembly 11 to rotate, and the encoder 54 outputs a corresponding rotation signal according to the amount of rotation of the rotating shaft.

[0080] The main control component 51 is used to determine the amount of rotation of the dial 10 relative to the second strap 30 based on the rotation signal, and to execute corresponding control actions based on the amount of rotation.

[0081] In this embodiment, optionally, the encoder 54 can be an incremental encoder 54, a hybrid encoder 54, or the like. As described in the above embodiment, during the movement of the dial 10 relative to the second strap 30, the sensing unit 40 drives the transmission assembly 11, which in turn drives the encoder 54. It is understood that the encoder 54 outputs a pulse signal or a sine wave signal every time it rotates a certain angle, and the outputs are 90 degrees out of phase with the A-phase output terminal and the B-phase output terminal. Therefore, the main control component 51 can determine the rotation angle of the rotating component when it moves on the sensing part 40 based on the pulse signal output from phase A of the encoder 54 and the pulse signal output from phase B (i.e., the rotation signal), as well as the phase difference relationship between the two signals (if phase A leads phase B by 90 degrees, it is clockwise rotation; if phase B leads phase A by 90 degrees, it is counterclockwise rotation). Then, according to the preset rotation angle-moving distance formula, the moving distance of the transmission component 11 on the sensing part 40 is obtained. Then, according to the preset moving distance-dial rotation angle formula, the current rotation angle and rotation direction of the dial 10 relative to the second strap 30 are determined. Finally, the corresponding control action is executed according to the rotation angle and rotation direction. Specifically, the transmission component 11 can be implemented using gears, and the sensing unit 40 can be implemented using a rack that wraps around the second strap 30. The gear rotates on the rack, and the direction of rotation of the gear on the rack is the same as the direction of rotation of the dial 10 relative to the second strap 30, thereby driving the rotating shaft of the encoder 54 to rotate. The main control component 51 determines the current rotation angle and rotation direction of the gear based on the rotation signal given by the encoder 54, and then calculates the distance moved by the gear on the rack according to the preset rotation angle-movement distance formula. Finally, it calculates the rotation angle of the dial 10 relative to the second strap 30 according to the preset movement distance-dial 10 rotation angle formula. The preset rotation angle-movement distance formula and the preset movement distance-dial 10 rotation angle formula can be obtained by the R&D personnel through multiple experiments during the design process, based on the actual structure and arrangement of the transmission component 11 and the sensing unit 40, and preset in advance in the main control component 51.

[0082] refer to Figure 3In one embodiment of the present invention, the sensing part 40 includes multiple sets of protrusions and concave portions, each set including a protrusion 42 and a groove 41, and the multiple sets of protrusions and concave portions are arranged in a wavy shape along the length direction of the second watch strap 30; or,

[0083] Multiple sets of protrusions and recesses are spaced apart along the length of the second strap 30.

[0084] In this embodiment, multiple sets of wavy protrusions and concave portions arranged along the extension direction of the second watch strap 30 can form a rack, and the transmission component 11 can be implemented using gears. Thus, the electronic control component 50 obtains the amount of rotation of the current dial 10 relative to the second watch strap 30 by detecting the amount of movement of the transmission component 11 on the rack.

[0085] Understandably, in another embodiment, multiple sets of protrusions and recesses are spaced at preset distances along the extension direction of the second strap 30. These preset distances can be pre-set by the developers according to actual needs; for example, the distance between every two protrusions and recesses could be α, and when the transmission component 11 of the dial 10 moves from one protrusion to another, the dial 10 rotates 10° relative to the second strap 30. Thus, in practical applications, the electronic control component 50 can determine the rotation angle of the dial 10 relative to the second strap 30 by detecting the number of protrusions and recesses the transmission component 11 passes through, i.e., the amount of movement of the transmission component 11 on the sensing part 40. This configuration also reduces the number of sensing parts 40 on the second strap 30, thereby reducing the weight of the entire smart wearable device, reducing its size, and improving user comfort.

[0086] Specifically, refer to Figure 3 In one embodiment of the present invention, the actuating component includes an actuating mechanism, which includes a pin. When the pin is in the groove 41, it returns from the rotating position to the initial position. When the pin is in the protrusion 42, it rotates from the initial position to the rotating position.

[0087] In this embodiment, multiple sets of protrusions and recesses are arranged in a wavy pattern along the extension direction of the second strap 30. The electronic control component 50 includes the main control component 51, potentiometer 53, and resistance detection component 52 as described in the above embodiment. It is understood that the actuation mechanism includes a reset component connected to the shift pin, such as a spring. The shift pin is connected to the rotation shaft of the potentiometer 53; that is, when the shift pin rotates between the rotation position and the initial position, it drives the rotation shaft of the potentiometer 53 to rotate, thereby changing the resistance value of the potentiometer 53. The rotation position includes a counter-clockwise rotation position and a clockwise rotation position, as shown in the reference... Figure 3 and Figure 5 , Figure 3The position of the dial setting needle in the example shown is the clockwise rotation position, that is, the position the needle will be in when the dial 10 rotates clockwise relative to the second strap 30. The counterclockwise rotation position is the position the dial 10 is in when it rotates counterclockwise relative to the second strap 30. In this embodiment, the initial resistance value of the potentiometer 53 is set to α. Since the multiple grooves 41 and protrusions 42 have the same structure, when the dial setting needle rotates from the initial position to the clockwise rotation position, the resistance value of the potentiometer 53 is α+β, and when the dial setting needle rotates from the initial position to the counterclockwise rotation position, the resistance value of the potentiometer 53 is α-β.

[0088] When the user pulls the first strap 20 to rotate the dial 10 counterclockwise relative to the second strap 30, the dial pin switches between counterclockwise and clockwise positions. When the main control component 51 detects the potentiometer 53 changing from α to α-β and back to α based on the resistance detection result of the resistance detection component 52, it confirms that the dial pin has passed one protrusion / concave section and that the dial 10 is rotating counterclockwise relative to the second strap 30. Therefore, the main control component 51 calculates the number of protrusion / concave sections the dial pin passes during the user's counterclockwise movement of the first strap 20, and calculates the rotation angle of the dial 10 relative to the second strap 30 based on the preset rotation angle corresponding to each protrusion / concave section. For example, if each protrusion / concave section corresponds to 2°, and the main control component 51 detects that the dial pin has passed 10 protrusion / concave sections (counterclockwise), it confirms that the dial 10 has rotated 20° counterclockwise relative to the second strap 30, and then executes the corresponding control action. The same principle applies when a user pulls the first strap 20 to rotate the dial 10 clockwise relative to the second strap 30, and will not be elaborated further. Thus, with the above settings, the range of potentiometer 53 and the rotation range of its shaft can be disregarded, thereby improving the user's experience and convenience when pulling the strap 00.

[0089] Furthermore, it should be considered that in practical applications, the dial pin may initially be in the protrusion 42 rather than the groove 41. Therefore, during the dialing process, the main control component 51 will only begin executing the calculation of how many grooves and protrusions the dial pin has traversed after the dial pin first entered the groove 41 (i.e., when the potentiometer 53 returns to its initial resistance value), to improve the accuracy of the calculation. Similarly, if the dial pin is not in the groove 41 when it stops, the main control component 51 can either exclude this groove or treat it as half a groove or protrusion in the calculation.

[0090] refer to Figure 4 There are multiple sensing units 40 and multiple transmission components 11, and the number of transmission components 11 and sensing units 40 is the same.

[0091] In this embodiment, there can be multiple sensing units 40, and the structure of the multiple sensing units 40 can include at least one type. Each sensing unit 40 is disposed at a different position on the second watch strap 30. Correspondingly, the structure of the transmission assembly 11 corresponding to each sensing unit 40 can also be different. Specifically, two sensing units 40 are disposed on the second watch strap 30, respectively disposed on the two side edges of the side of the second watch strap 30 opposite to the dial 10. One sensing unit 40 is a plurality of convex and concave portions arranged in a wave-like pattern along the extending direction of the second watch strap 30 in the above embodiment, and the other sensing unit 40 is a rack and pinion guide rail disposed on the second watch strap 30.

[0092] Optionally, in one embodiment, the electronic control component 50 detects only the movement of the transmission component 11 corresponding to one of the sensing units 40, determines the rotation of the dial 10 relative to the second strap 30 based on the movement, and executes corresponding control actions based on the rotation. The other transmission components 11 and sensing units 40 can stabilize the dial 10, thereby preventing it from easily deviating when the first strap 20 drives the dial 10 to move relative to the second strap 30, thus ensuring the stability of its rotation.

[0093] Optionally, in one embodiment, the electronic control component 50 is further configured to detect the amount of movement of at least two of the transmission components 11, determine the amount of rotation of the dial 10 relative to the second strap 30 based on the amount of movement of the at least two transmission components 11, and perform corresponding control actions based on the amount of rotation.

[0094] In this embodiment, the electronic control component 50 can also detect the amount of movement of at least two transmission components 11 on the sensing part 40, and determine the amount of rotation of at least two dials 10 relative to the second strap 30 based on the detected at least two amounts of movement, and process the at least two amounts of rotation.

[0095] Optionally, in one embodiment, the electronic control component 50 averages the acquired at least two rotation amounts to obtain an average rotation angle, and performs the control action based on the average rotation angle as described in the above embodiment. Thus, in practical applications, if one or more transmission components 11 malfunction or one or more sensing units 40 are damaged, causing the electronic control component 50 to detect a movement of 0 or a very small value for the transmission component 11, then when the user pulls the first strap 20 to move the dial 10 on the second strap 30, the electronic control component 50 can still detect the movement of other normal transmission components 11 and the corresponding sensing units 40. Ultimately, it can also calculate a certain rotation amount through averaging, thereby ensuring that even if one or more transmission components 11 malfunction or one or more sensing units 40 are damaged, the user can still control the smart wearable device by pulling the first strap 20 to move the dial 10 on the second strap 30. Furthermore, it is understood that in another embodiment, when the electronic control component 50 detects that the movement of one or more transmission components 11 is 0, while the movement of other transmission components 11 is non-zero, the transmission component 11 with the movement of 0 can be directly identified as faulty, and the rotation amount can be obtained based on the movement of other normal transmission components 11.

[0096] Optionally, in another embodiment, the electronic control component 50 compares at least two obtained rotational quantities. If the difference between the rotational angles of all current rotational quantities is less than a preset angle difference and the rotational directions are consistent, then the electronic control component 50 can confirm that the current detection process of the transmission component 11 is normal, and perform corresponding action control based on multiple rotational quantities, such as performing corresponding control actions based on the average value of the rotational angles. If the difference between the rotational angles of all current rotational quantities is greater than a preset angle difference or the rotational directions are inconsistent, then the electronic control component 50 can confirm that one or more detection components used to detect the movement of the transmission component 11 are malfunctioning, and will not execute any control actions. Furthermore, it will prompt the user of the current rotational detection failure through a prompting component, such as a touchscreen. In practical applications, this effectively prevents the erroneous triggering of control actions due to malfunctions of the detection components in the electronic control component 50 used to detect the movement of the transmission component 11, ensuring a positive user experience when using the smart wearable device.

[0097] Specifically, refer to Figure 4 ,by Figure 4 The following is an example of an embodiment. Figure 4There are two sensing units 40, which are respectively located on the two edges of the side of the second strap 30 opposite to the dial 10. Each sensing unit 40 consists of multiple sets of concave and convex portions arranged in a wave-like pattern along the extension direction of the second strap 30 as described in the above embodiment. Correspondingly, two transmission components 11 are provided inside the dial 10. After detecting the movement of the two transmission components on the sensing units 40 according to the process of the above embodiment, the electronic control component 50 converts it into the corresponding rotation angle and rotation direction of the dial 10 relative to the second strap 30. If the difference between the two rotation angles is less than a preset angle difference and the rotation directions are consistent, the electronic control component 50 will calculate the average value of the two rotation angles and then execute the corresponding up / down sliding action based on the calculation result and rotation direction. If the difference between the two rotation angles is greater than the preset angle difference or the rotation directions are inconsistent, the up / down sliding action will be stopped, and the user will be notified of the abnormal rotation of the dial 10 via the touch screen on the dial 10.
