Detailed Implementation

[0030] The technical solutions of the embodiments of this application 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 this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The terms "first" and "second" in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] During the research process of this application, it was found that smart wearable devices can realize functions such as health monitoring, motion tracking, information reminders, voice assistants, navigation, and playback control. With the development of technologies such as AR, VR, and MR, head-mounted wearable devices can bring users a deeper digital experience. One interaction method for such devices is to set physical control buttons or capacitive sensors on the shell of the head-mounted device to achieve interaction. Other interaction methods include using cameras to collect the user's hand posture, such as finger pinching and palm swiping, to achieve interaction. There are also interaction methods that combine external wearable devices such as smart rings and bracelets. However, most of these devices use inertial sensors, capacitive sensors, etc., to establish a communication connection with the device to be interacted with through touch to achieve interaction. Moreover, this type of sensor interaction method is prone to accidental touches or false detections. Therefore, designing a more novel, easy-to-operate, and interaction-efficient wearable device has become an urgent problem to be solved.

[0034] To address the aforementioned problems, this application provides a novel smart wearable device. Please refer to... Figures 1 to 3 , Figure 18 , Figure 1 This is a schematic diagram of the overall structure of the smart wearable device provided in this application; Figure 2 This is a schematic diagram of the disassembled structure of the smart wearable device provided in this application; Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure of the provided smart wearable device along the EE direction; Figure 18 This is a schematic diagram illustrating the connection between the smart wearable device (e.g., a smart ring) and the terminal device provided in this application.

[0035] The smart wearable device 100 of this application can communicate with external terminal devices 300, such as smartphones, computers, tablets, AR, VR, MR, near-eye display devices, smart glasses and other head-mounted devices. The smart wearable device 100 can interact with the terminal device 300 or perform related graphical interface function interactions, such as interactions related to graphical interface operation functions such as swiping to browse, turning pages, confirming, deleting and so on.

[0036] The smart wearable device 100 provided in this application may include a first housing 10, a second housing 20, an electrical tracking component 40, and a circuit board assembly 30; the second housing 20 is sleeved on the outside of the first housing 10; the electrical tracking component 40 is disposed between the first housing 10 and the second housing 20; and the circuit board assembly 30 is disposed between the first housing 10 and the second housing 20. The second housing 20 and the first housing 10 are configured to move relative to each other and drive the electrical tracking component 40 and the circuit board assembly 30 to trigger electrical signals.

[0037] Specifically, the first housing 10 is sleeved around the second housing 20, forming an annular cavity 80 between the first annular housing and the second housing 20. The electrical trace assembly 40 and the circuit board assembly 30 are both disposed between the first housing 10 and the second housing 20. For example, both the first housing 10 and the second housing 20 are annular and coaxially arranged. Both the first housing 10 and the second housing 20 can be made of insulating material to prevent short circuits with the electrical trace assembly 40 and the circuit board assembly 30.

[0038] In one embodiment, the electrical trajectory component 40 is disposed on the outer side of the first housing 10, so the first housing 10 can drive the electrical trajectory component 40 to rotate; the circuit board assembly 30 is disposed on the inner side of the second housing 20, so the second housing 20 can drive the electrical circuit board assembly 30 to rotate. Meanwhile, the circuit board assembly 30 is disposed on the outer side of the electrical trajectory component 40, allowing the length of the circuit board 32 to be set to a longer length as needed, while also facilitating the processing of the circuit board assembly 30 and the overall installation of the smart wearable device 100.

[0039] The electrical trace assembly 40 and the circuit board assembly 30 are positioned close to each other. The surface of the circuit board assembly 30 adjacent to the electrical trace assembly 40 has a conductive printed layer 33. The second housing 20 and the first housing 10 are configured to move relative to each other and cause the electrical trace assembly 40 and the circuit board assembly 30 to cooperate in triggering an electrical signal. It can be understood that the second housing 20 causes one of the two housings, the first housing 10, to rotate relative to the other. For example, the second housing 20 causes the circuit board assembly 30 to rotate relative to the first housing 10 and the electrical trace assembly 40, thereby allowing a portion of the electrical trace assembly 40 to contact the circuit board assembly 30 to trigger an electrical signal.

[0040] In one embodiment, the second housing 20 is rotatable relative to the first housing 10, thereby causing the electrical trace assembly 40 and the circuit board assembly 30 to cooperate in triggering the first electrical signal. Specifically, in this embodiment, the second housing 20 is rotated relative to the first housing 10. Since the circuit board assembly 30 is disposed on the inner side of the second housing 20, during the rotation of the second housing 20, the circuit board assembly 30 can be driven to rotate synchronously, thereby allowing the conductive printed layer 33 disposed on the surface of the circuit board assembly 30 near the electrical trace assembly 40 to contact a portion of the electrical trace assembly 40 to trigger the first electrical signal.

[0041] Meanwhile, the second housing 20 can also move radially relative to the first housing 10, that is, the second housing 20 is offset from the center of the first housing 10; for example, the second housing 20 can also move radially relative to the first housing 10 during the rotation of the second housing 20 relative to the first housing 10, for example, by pressing the second housing 20 so that the second housing 20 moves closer to the first housing 10 radially in a localized manner, thereby driving the electrical trajectory assembly 40 and the circuit board assembly 30 to cooperate in triggering the second electrical signal.

[0042] In this embodiment, the first electrical signal can be a signal triggered during the rotation of the second housing 20, and the second electrical signal can be a signal triggered during the pressing of the second housing 20. The functions corresponding to the first and second electrical signals are different. For example, the first electrical signal can correspond to interactive function signals on the interface of the external terminal device 300, such as page turning or swiping, generated by rotation, while the second electrical signal can correspond to interactive function signals on the interface of the external terminal device 300, such as confirmation, generated by pressing. In other embodiments, the first and second electrical signals can be used to switch the functions of the smart wearable device 100, adjust the sound of the smart wearable device 100, etc., and can be set as needed. It is understood that the rotation and pressing operations of the second housing 20 can be performed separately, so that the rotation and pressing operations trigger different functions respectively. Alternatively, the rotation and pressing operations of the second housing 20 can be performed simultaneously, for example, while rotating the second housing 20, a certain pressing force is applied simultaneously, so that the first and second electrical signals are triggered simultaneously.

[0043] Please see Figures 4 to 11 , Figure 4 This is a schematic diagram of the overall connection structure of the electrical trajectory assembly, circuit board assembly and battery provided in this application; Figure 5 This is a partially disassembled structural diagram of the electrical trajectory assembly, circuit board assembly, and battery provided in this application; Figure 6 yes Figure 5 The provided enlarged structural diagram of part B; Figure 7 This is a schematic diagram of an unfolded structure of the conductive printed layer provided in the first embodiment of this application; Figure 8 This is a schematic diagram of an unfolded structure of the conductive printed layer provided in the second embodiment of this application; Figure 9 This is another schematic diagram of the unfolded structure of the conductive printed layer provided in the first embodiment of this application; Figure 10 This is another unfolded structural diagram of the conductive printed layer provided in the second embodiment of this application; Figure 11 This is a schematic diagram of the structure of the electrical trajectory component provided in this application.

[0044] like Figure 4As shown, the electrical trajectory assembly 40 may include a first trajectory segment 411 and a bracket 42, with the bracket 42 fixedly sleeved on the outer side of the first housing 10. The first trajectory segment 411 moves to a first position D1 and adheres to the conductive printed layer 33, allowing the first trajectory segment 411 to contact and conduct with the conductive printed layer 33, thereby triggering a first electrical signal or a second electrical signal. Figure 4 As shown, in the first implementation, the first end 4111 of the first trajectory segment 411 is fixedly connected to the bracket 42, for example by means of snap-fit, adhesive or welding (e.g. spot welding), and the second end 4112 is elastically abutted against the conductive printed layer 33.

[0045] like Figure 11 As shown, the first trajectory segment 411 can be bent to form a first recess 4114 on one side and a first protrusion 4113 facing the conductive printed layer 33 on the other side. The first protrusion 4113 is provided corresponding to the first recess 4114. The first protrusion 4113 protrudes in a direction away from the bracket 42, and the first protrusion 4113 elastically abuts against the conductive printed layer 33, thereby realizing the electrical connection between the first trajectory segment 411 and the conductive printed layer 33. The first protrusion 4113 can be a protrusion or a bump.

[0046] Multiple first trajectory segments 411 are spaced apart circumferentially along the bracket 42, and each first trajectory segment 411 is preferably located at the axial center of the bracket 42. For example, the first end 4111 of the first trajectory segment 411 is fixed to the bracket 42, and the second end 4112 naturally tilts upwards when no external force is applied; the second end 4112 of the first trajectory segment 411 is pressed down when an external force is applied, so that the first protrusion 4113 abuts against the conductive printed layer 33, thereby achieving elastic contact between the first trajectory segment 411 and the conductive printed layer 33.

[0047] In the second implementation, an elastic element 43 can be further provided between the first trajectory segment 411 and the bracket 42. The elastic element 43 drives the second end 4112 of the first trajectory segment 411 to elastically abut against the conductive printed layer 33. Specifically, the elastic element 43 can elastically abut against the first protrusion 4113. By providing the elastic element 43, the first protrusion 4113 can be prevented from deforming after being pressed repeatedly and from failing to return to its natural raised state when no external force is applied. For example, when the elastic element 43 is compressed, the first trajectory segment 411 elastically abuts against the conductive printed layer 33 to achieve electrical connection; when the elastic element 43 returns to its natural state, the elastic element 43 supports the second end 4112 of the first trajectory segment 411, causing the first trajectory segment 411 to move away from the conductive printed layer 33, thereby disconnecting the electrical connection between the first trajectory segment 411 and the conductive printed layer 33. The elastic element 43 can be a spring or an elastic column, for example, made of rubber, plastic, or elastic metal. For example, the overall shape of the elastic element 43 can be cylindrical, truncated, or frustum-shaped. The elastic element 43 can also be made of insulating material. It is understood that when both the elastic element 43 and the bracket 42 are made of metal, an insulating layer (not shown) needs to be provided between them to prevent short circuits. Similarly, when the bracket 42 is made of metal, an insulating layer also needs to be provided between the first trajectory segment 411 and the bracket 42 to prevent short circuits. In this embodiment, the bracket 42 is made of insulating material, and the first trajectory segment 411 is made of metal. The bracket 42 can be a ring-shaped bracket to facilitate installation with other ring-shaped components; alternatively, the bracket 42 can be composed of multiple arc-shaped portions (not shown) joined together. This application does not limit this.

[0048] It is understood that either of the above two implementation methods can be selected, or both can be set. That is, the first end 4111 of the first trajectory segment 411 is fixedly connected to the bracket 42, and an elastic element 43 is set between the second end 4112 and the bracket 42. The specific settings can be made as needed, and this application does not impose any restrictions on them.

[0049] In one embodiment, the first trajectory segment 411 is disposed on the elastic member 43 and engages with the elastic member 43; and a portion of the first trajectory segment 411 (specifically the second end 4112) is suspended on the side of the first fixed segment 4121 and the second fixed segment 4131 away from the bracket 42 to form a second gap 45.

[0050] Furthermore, the bracket 42 has an opening 421, and part of the elastic member 43 is embedded in the opening 421, while part protrudes out of the opening 421 and engages in the first recess 4114. Specifically, the elastic member 43 and the first recess 4114 cooperate to fix the first trajectory segment 411 stably and firmly. The opening 421 can be a through hole or a blind hole. In this embodiment, the opening 421 is specifically a through hole, through which the elastic member 43 engages with the bracket 42. Since the bracket 42 is relatively thin, the elastic member 43 can further pass through the through hole and abut against the first housing 10, making the elastic member 43 more stably fixed.

[0051] like Figures 7 to 8 As shown, in one embodiment, the conductive printed layer 33 may include a first electrical region 331 and a second electrical region 332 that are insulated from each other; both the first electrical region 331 and the second electrical region 332 extend in an arc shape along the circumference of the second housing 20. In this embodiment, the first electrical region 331 and the second electrical region 332 may further be an arc.

[0052] In this embodiment, since the electrical trajectory component 40 is disposed on the outer surface of the first housing 10, during the rotation of the second housing 20 relative to the first housing 10, it can drive the first trajectory segment 411 to rotate relative to the conductive printed layer 33, and drive the first trajectory segment 411 to move alternately between the first position D1 and the second position D2, so that the first electrical region 331 and the second electrical region 332 alternately switch between two states: open circuit and being turned on by the first trajectory segment 411. That is, during the rotation of the first trajectory segment 411 driven by the first housing 10, the first trajectory segment 411 can move along the extension direction of the first electrical region 331 and the second electrical region 332. When the first trajectory segment 411 moves to the first position D1, and both ends of it are simultaneously connected to the first electrical region 331 and the second electrical region 332, then the first electrical region 331 and the second electrical region are connected by the first trajectory segment 411. When the first trajectory segment 411 moves to the second position D2, it connects only one of the first electrical region 331 and the second electrical region 332, or when the first trajectory segment 411 moves to a position where it is not connected to either the first electrical region 331 or the second electrical region 332, such as the second position D2, then the first electrical region 331 and the second electrical region cannot be connected and are in an open circuit state. It can be understood that, for example... Figures 8-11As shown, the first position D1 is the position where the first electrical region 331 and the second electrical region 332 are connected during the movement of the first trajectory segment 411 along the extension direction of the first electrical region 331 and the second electrical region 332, and the first position D1 is not unique; the second position D2 is the position where the first electrical region 331 and the second electrical region 332 are not connected during the movement of the first trajectory segment 411 along the extension direction of the first electrical region 331 and the second electrical region 332, and the second position D2 is not unique.

[0053] In one embodiment, such as Figures 7 to 8 As shown, the first electrical region 331 may include a first strip-shaped portion 3311 and a plurality of first protrusions 3312 connected to the first strip-shaped portion 3311 near the side of the second electrical region 332; the second electrical region 332 may include a second strip-shaped portion 3321 and a plurality of second protrusions 3322 connected to the second strip-shaped portion 3321 near the side of the first electrical region 331. Figure 7 As shown, along the circumferential direction, a plurality of first protrusions 3312 and a plurality of second protrusions 3322 are periodically alternated and spaced apart along a first direction (circumferential direction). For example, for each of the plurality of first protrusions 3312 and each of the plurality of second protrusions 3322, the first protrusions 3312 and the second protrusions 3322 may be arranged alternately one by one along the first direction. In some embodiments, a first protrusion 3312 and a group of several second protrusions 3322 may be periodically alternated along the first direction, wherein the number of the several second protrusions 3322 is at least two. Alternatively, a group of several first protrusions 3312 and a second protrusion 3322 may be periodically alternated along the first direction, wherein the number of the several first protrusions 3312 is at least two. The first protrusions 3312 and the second protrusions 3322 may also be spaced apart from each other along the first direction, as in some embodiments, such as Figure 8 As shown, a plurality of first protrusions 3312 and a plurality of second protrusions 3322 are arranged opposite each other in pairs along the circumferential direction. For example, for each of the plurality of first protrusions 3312 and each of the plurality of second protrusions 3322, two first protrusions 3312 and two second protrusions 3322 may be arranged opposite each other in pairs along the circumferential direction. In some embodiments, the circumferential direction may refer to the circumferential direction of any one of the first housing 10, the second housing 20, the third housing 31, the circuit board 32, the battery 50, and the annular cover 60.

[0054] Specifically, the circumferential width Wz of the first protrusion 3312 and the second protrusion 3322 can be the same or different, and in this embodiment, they are preferably the same. The shapes of the first protrusion 3312 and the second protrusion 3322 can be the same or different, and both shapes can be rectangular, arc-shaped, or triangular, etc., and this application does not impose any restrictions on this. In this embodiment, it is preferred that the first protrusion 3312 and the second protrusion 3322 have the same shape, so that the first trajectory segment 411 can connect and conduct between the first protrusion 3312 and the second protrusion 3322 during rotation.

[0055] In the first embodiment, as Figure 7 As shown, a third barrier region 330 is provided between the first electrical region 331 and the second electrical region 332, and the third barrier region 330 is meandering. The third barrier region 330 is periodically arranged along a first direction (circumferential direction) and electrically isolates the first electrical region 331 and the second electrical region 332. The meandering arrangement can be understood as the edge of the third barrier region 330 extending in a non-linear manner. Specifically, insulation can be achieved by an irregularly shaped third barrier region 330 formed between multiple first protrusions 3312 and multiple second protrusions 3322. In a specific embodiment, as... Figure 7 As shown, the third barrier zone 330 has a constant width along the first direction and is arranged in a meandering manner.

[0056] like Figure 8As shown, in the second embodiment, the third barrier region 330 may include a plurality of alternating first sub-barrier regions 3301 and a plurality of second sub-barrier regions 3302. In some embodiments, the plurality of first sub-barrier regions 3301 and the plurality of second sub-barrier regions 3302 may be periodically alternating along the periphery. In some embodiments, for each of the plurality of first sub-barrier regions 3301 and each of the plurality of second sub-barrier regions 3302, the first sub-barrier regions 3301 and the second sub-barrier regions 3302 may be arranged one after another. In some embodiments, a first sub-barrier region 3301 and a group of several second sub-barrier regions 3302 may be periodically alternating along the periphery. Alternatively, a group of several first sub-barrier regions 3301 and a second sub-barrier region 3302 may be periodically alternating along the periphery. The width of the first sub-barrier region 3301 is greater than the width of the second sub-barrier region 3302. For example, the width of the first sub-blocking region 3301 (first width W1) is such that during the movement of the first trajectory segment 411 along the extension direction of the first electrical region 331 and the second electrical region 332, it does not contact at least one of the first electrical region 331 and the second electrical region 332, so that the first electrical region 331 and the second electrical region 332 are in an open circuit state; while the width of the second sub-blocking region 3302 (second width W2) is such that during the movement of the first trajectory segment 411 along the extension direction of the first electrical region 331 and the second electrical region 332, it can contact both the first electrical region 331 and the second electrical region 332 to achieve electrical connection, so that the first electrical region 331 and the second electrical region 332 are in a conductive state. It is understood that when setting the first sub-blocking region 3301, its first width W1 in the circumferential direction can be greater than the width of the first trajectory segment 411; when setting the second sub-blocking region 3302, its second width W2 in the circumferential direction can be less than the width of the first trajectory segment 411. The specific width values ​​of the first width W1 and the second width W2 can be set as needed, and this application does not impose any restrictions on them. In a specific embodiment, the third blocking region 330 is an axisymmetric shape.

[0057] In one embodiment, such as Figure 10 As shown, the first strip portion 3311 and the second strip portion 3321 extend in the same direction; wherein, along the extension direction of the first strip portion 3311 and the second strip portion 3321, the distance between two adjacent first protrusions 3312 gradually increases, and the distance between two adjacent second protrusions 3322 gradually increases.

[0058] Specifically, it can be understood that in the extending directions of the first strip portion 3311 and the second strip portion 3321, the increasing spacing between two adjacent first protrusions 3312 and the increasing spacing between two adjacent second protrusions 3322 can be the same or different. In this application, the increasing spacing between two adjacent first protrusions 3312 and the increasing spacing between two adjacent second protrusions 3322 are the same, so that the dimensions of the relatively disposed first protrusions 3312 and second protrusions 3322 can be kept consistent, thereby facilitating the simultaneous contact between the first trajectory segment 411 and the first protrusions 3312 and the second protrusions 3322 during movement to achieve the conduction of the first electrical region 331 and the second electrical region 332. It can also be understood that the gradually increasing spacing between two adjacent first protrusions 3312 and the gradually increasing spacing between two adjacent second protrusions 3322 can also be used to determine the rotation direction of the second housing 20 of the smart wearable device 100. For example, if the distance between two adjacent first protrusions 3312 and two adjacent second protrusions 3322 gradually increases, the interval between the first electrical region 331 and the second electrical region 332 being connected by the first trajectory segment 411 gradually increases, thus indicating that the second housing 20 is rotating clockwise. Conversely, if the distance between two adjacent first protrusions 3312 and two adjacent second protrusions 3322 gradually decreases, the interval between the first electrical region 331 and the second electrical region 332 being connected by the first trajectory segment 411 gradually decreases, thus indicating that the second housing 20 is rotating counterclockwise. This method helps determine the rotation direction of the second housing 20, reducing the likelihood of accidental touches and improving touch accuracy.

[0059] Or, such as Figure 9As shown, along the extending directions of the first strip 3311 and the second strip 3321, the lengths of the plurality of first protrusions 3312 gradually increase, and the lengths of the plurality of second protrusions 3322 also gradually increase. Similarly, it can be understood that, in addition to determining the rotation direction of the second housing 20 by gradually increasing the distance between two adjacent first protrusions 3312 and the distance between two adjacent second protrusions 3322, the rotation direction of the second housing 20 can also be determined by increasing the lengths of the plurality of first protrusions 3312 and the plurality of second protrusions 3322 themselves. For example, if the lengths of the multiple first protrusions 3312 and the multiple second protrusions 3322 gradually increase, the time for the first electrical region 331 and the second electrical region 332 to be connected by the first trajectory segment 411 gradually increases, thus indicating that the second housing 20 is rotating clockwise. Conversely, if the lengths of the multiple first protrusions 3312 and the multiple second protrusions 3322 gradually decrease, the time for the first electrical region 331 and the second electrical region 332 to be connected by the first trajectory segment 411 gradually decreases, thus indicating that the second housing 20 is rotating counterclockwise. This method is used to determine the rotation direction of the second housing 20, thereby reducing the likelihood of accidental touches and improving touch accuracy.

[0060] In one embodiment, the conductive printed layer 33 may further include a third electrical region 333 and a fourth electrical region 334 that are insulated from each other; both the third electrical region 333 and the fourth electrical region 334 extend in an arc shape along the circumference of the second housing 20. In this embodiment, the third electrical region 333 and the fourth electrical region 334 may further be arc-shaped.

[0061] In one embodiment, such as Figures 7 to 8As shown, along the axial direction, the third electrical region 333 is located on the side of the first electrical region 331 away from the second electrical region 332 and is insulated from the first electrical region 331; the fourth electrical region 334 is located on the side of the second electrical region 332 away from the first electrical region 331 and is insulated from the second electrical region 332. That is, the third electrical region 333 and the fourth electrical region 334 can be located on opposite sides of the overall region formed by the first electrical region 331 and the second electrical region 332, for example, the first strip portion 3311 of the first electrical region 331, the second strip portion 3321 of the second electrical region 332, the third electrical region 333 and the fourth electrical region 334 can be arranged side by side in the axial direction. At the same time, the first electrical region 331 and the second electrical region 332 can be insulated from each other by an irregularly shaped third barrier region 330 formed between a plurality of first protrusions 3312 and a plurality of second protrusions 3322. A first barrier region 336 and a second barrier region 335 are provided between the third electrical region 333 and the fourth electrical region 334. The first electrical region 331 and the third electrical region 333 are insulated from each other by the first barrier region 336; the second electrical region 332 and the fourth electrical region 334 are insulated from each other by the second barrier region 335. Preferably, the first barrier region 336 and the second barrier region 335 are arranged in parallel, and the third electrical region 333 and the fourth electrical region 334 are arranged in parallel. The first barrier region 336 and the second barrier region 335 can extend irregularly or regularly. In this embodiment, it is preferred that they extend regularly, specifically that the first barrier region 336 and the second barrier region 335 are rectangular.

[0062] Accordingly, such as Figures 4 to 11 As shown, the electrical trajectory component 40 may further include a second trajectory segment 412 and a third trajectory segment 413. The second trajectory segment 412 is electrically connected to the third electrical region 333, and the third trajectory segment 413 is electrically connected to the fourth electrical region 334. The first trajectory segment 411 is switchable between an initial state and a pressed state. In the initial state (second position D2), the first trajectory segment 411 is not in contact with the second trajectory segment 412 and the third trajectory segment 413, thus the second trajectory segment 412 and the third trajectory segment 413 are in an open circuit state, thereby disconnecting the third electrical region 333 and the fourth electrical region 334. In the pressed state (first position D1), the first trajectory segment 411 is in contact with both the second trajectory segment 412 and the third trajectory segment 413, thereby connecting the third electrical region 333 and the fourth electrical region 334. Meanwhile, as the second housing 20 moves radially relative to the first housing 10, it can drive the first trajectory segment 411 to switch to a pressing state, so that the third electrical region 333 and the fourth electrical region 334 are connected by the first trajectory segment 411.

[0063] Specifically, the first trajectory segment 411, the second trajectory segment 412, and the third trajectory segment 413 can together form a circular trajectory plate 41. In the initial state (second position D2), the second trajectory segment 412 and the third trajectory segment 413 are not connected by the first trajectory segment 411. Therefore, even if the second trajectory segment 412 is electrically connected to the third electrical region 333 and the third trajectory segment 413 is electrically connected to the fourth electrical region 334, the third electrical region 333 and the fourth electrical region 334 will not be connected by the first trajectory segment 411. In the pressed state (first position D1), the first trajectory segment 411 contacts the second trajectory segment 412 and the third trajectory segment 413 simultaneously, making the second trajectory segment 412 and the third trajectory segment 413 conductive. Since the second trajectory segment 412 is electrically connected to the third electrical region 333 and the third trajectory segment 413 is electrically connected to the fourth electrical region 334, the third electrical region 333 and the fourth electrical region 334 are indirectly connected by the first trajectory segment 411, so that the entire electrical trajectory component 40 and the conductive printed layer 33 are in a conductive state, thereby triggering the first electrical signal and the second electrical signal to achieve the corresponding function.

[0064] It is understandable that if the bracket 42 is made of metal, then an insulating layer (not shown) needs to be covered on the outer wall of the corresponding second track segment 412 and third track segment 413 to prevent short circuit caused by electrical contact between the second track segment 412 and the third track segment 413 and the bracket 42.

[0065] In one embodiment, during the rotation of the second housing 20 relative to the first housing 10, the second trajectory segment 412 and the third trajectory segment 413 are driven to rotate relative to the conductive printed layer 33, while maintaining the second trajectory segment 412 in contact with the third electrical region 333 and the third trajectory segment 413 in contact with the fourth electrical region 334. That is, during the rotation of the second trajectory segment 412 and the third trajectory segment 413 relative to the conductive printed layer 33, the second trajectory segment 412 and the third electrical region 333 are always electrically connected, and the third trajectory segment 413 and the fourth electrical region 334 are always electrically connected.

[0066] In one embodiment, the second trajectory segment 412 may include a first fixed segment 4121 fixedly sleeved on the bracket 42 and a plurality of first spring pieces 4122 connected to the first fixed segment 4121. Each first spring piece 4122 has a third gap 46 between it and the first fixed segment 4121. The plurality of first spring pieces 4122 may be arranged in a ring on the side of the first fixed segment 4121 away from the third trajectory segment 413, and the first spring pieces 4122 are elastically fitted with the third electrical region 333. The elastic fit can be understood as the first spring piece 4122 being similar to a cantilever disposed on one side of the first fixed segment 4121, so that the first spring piece 4122 can move closer to or further away from the third electrical region 333.

[0067] In a further embodiment, such as Figure 11 As shown, one end of the first spring piece 4122 is connected to the edge of the first fixing segment 4121 away from the second fixing segment 4131. The other end of the first spring piece 4122 is bent to form a second recess 4124 and a second protrusion 4123 facing the conductive printed layer 33. The second protrusion 4123 elastically fits into the third electrical region 333 to achieve electrical connection. The second protrusion 4123 can be configured as a protrusion or a protrusion structure. Both the first fixing segment 4121 and the second fixing segment 4131 can adopt a ring structure. Specifically, the first fixing segment 4121 can be a first fixing ring, and the second fixing segment 4131 can be a second fixing ring. In other embodiments, the number of first fixing segments 4121 can be multiple, and these first fixing segments 4121 can collectively form a ring structure. The spacing between two adjacent first fixed segments 4121 can be set to be equidistant, thereby generating a synchronous timing signal during the electrical connection between the second protrusion 4123 and the third electrical region 333; alternatively, they can be set to be non-equidistant, thereby generating differentiated timing signals during the process. In other embodiments, a plurality of first fixed segments 4121 may be partially equidistant while the rest are non-equidistant, and the specific configuration can be adjusted according to actual needs.

[0068] In one embodiment, the third trajectory segment 413 may include a second fixing segment 4131 fixedly sleeved on the bracket 42 and a plurality of second spring pieces 4132 connected to the second fixing segment 4131. Each second spring piece 4132 has a fourth gap 47 between it and the second fixing segment 4131. The second fixing segment 4131 and the first fixing segment 4121 may be arranged parallel to each other. The second spring piece 4132 is located on the side of the second fixing segment 4131 opposite to the first fixing segment 4121. One end of the second spring piece 4132 is connected to the edge of the second fixing segment 4131 away from the first fixing segment 4121, and the other end of the second spring piece 4132 is bent to form a third recess 4134 and a third protrusion 4133 facing the conductive printed layer 33. The third protrusion 4133 elastically fits the fourth electrical region 334 to achieve electrical connection. The third protrusion 4133 may be a protrusion or a raised part. In some embodiments, the number of second fixing segments 4131 may be multiple. Multiple second fixed segments 4131 can cooperate to form a ring structure. In some embodiments, the spacing between any two adjacent second fixed segments 4131 can be equal, that is, the multiple second fixed segments 4131 can be arranged at equal intervals. Thus, when the third protrusion 4133 establishes an electrical connection with the fourth electrical region 334, the same timing signal can be generated. In other embodiments, the spacing between any two adjacent second fixed segments 4131 can be unequal, that is, the multiple second fixed segments 4131 can be arranged at non-equal intervals. In this case, different timing signals will be generated during the process of establishing an electrical connection between the third protrusion 4133 and the fourth electrical region 334. Furthermore, there is also a hybrid configuration scheme where some second fixed segments 4131 are arranged at equal intervals, and the remaining parts are arranged at non-equal intervals; the specific configuration can be adjusted according to actual needs.

[0069] During the rotation of the second track segment 412 and the third track segment 413 relative to the conductive printed layer 33, multiple first springs 4122 respectively contact the third electrical region 333 to achieve electrical connection, and multiple second springs 4132 respectively contact the fourth electrical region 334 to achieve electrical connection.

[0070] In one embodiment, both the first fixing segment 4121 and the second fixing segment 4131 are annular and are fitted onto the outer side of the bracket 42. A plurality of first elastic tabs 4122 are spaced apart circumferentially along the first fixing segment 4121, and a plurality of second elastic tabs 4132 are spaced apart circumferentially along the second fixing segment 4131. The plurality of second elastic tabs 4132 can be arranged annularly on the side of the second fixing segment 4131 away from the second trajectory segment 412, and the second elastic tabs 4132 elastically adhere to the fourth electrical region 334. This elastic adhesion is based on the same principle as the elastic adhesion between the first elastic tab 4122 and the third electrical region 333. The second protrusion 4123 and the third protrusion 4133 both protrude in a direction away from the bracket 42 and are both higher than the protrusion height of the first fixing segment 4121.

[0071] In this embodiment, the second trajectory segment 412 and the third trajectory segment 413 can have the same structure and are symmetrically arranged. The first fixed segment 4121 and the second fixed segment 4131 are arranged close to each other but do not contact each other. The second trajectory segment 412 and the third trajectory segment 413 are symmetrically arranged along the axial direction; or, the second trajectory segment 412 and the third trajectory segment 413 are centrally symmetrically arranged. For example, the second trajectory segment 412 and the third trajectory segment 413 are symmetrically arranged and have a first gap 44 between them. The first trajectory segment 411 is disposed within the first gap 44 and does not contact the second trajectory segment 412 and the third trajectory segment 413 in the initial state.

[0072] Specifically, a first gap 44 exists between the first fixed segment 4121 and the second fixed segment 4131; one end of the first track segment 411 passes through the first gap 44 and is fixedly connected to the bracket 42, while the other end is suspended on the side of the first fixed segment 4121 and the second fixed segment 4131 away from the bracket 42, forming a second gap 45. It can be understood that, as Figure 6 , Figure 11 As shown, the first gap 44 is the gap reserved between the first fixed segment 4121 and the second fixed segment 4131 when they are symmetrically arranged, and the second gap 45 is the gap formed between the first trajectory segment 411 and the bracket 42 when they are not in radial contact.

[0073] In this embodiment, the first fixing segment 4121 and the first spring piece 4122 are both metal sheets and integrally formed; the second fixing segment 4131 and the second spring piece 4132 are both metal sheets and integrally formed. It can be understood that the integral forming method facilitates manufacturing and also makes the components more robust.

[0074] In some embodiments, such as Figure 6 , Figure 11As shown, along the circumferential direction, the first gap 44 may include a plurality of alternating first sub-gap 441 and second sub-gap 442. In some embodiments, the plurality of first sub-gap 441 and the plurality of second sub-gap 442 may be arranged periodically alternating along the circumferential direction. For example, for each of the plurality of first sub-gap 441 and each of the plurality of second sub-gap 442, in some embodiments, the first sub-gap 441 and the second sub-gap 442 are arranged alternately along the circumferential direction. In some embodiments, one first sub-gap 441 and a set of a plurality of second sub-gap 442 are arranged alternately along the circumferential direction. The number of the plurality of second protrusions 3322 may be at least two. Alternatively, a set of a plurality of first sub-gap 441 and a second sub-gap 442 may be arranged alternately along the circumferential direction. The number of the plurality of second protrusions 3322 may be at least two. The width of the first sub-gap 441 is greater than the width of the second sub-gap 442 to accommodate the first trajectory segment 411, and such that the first trajectory segment 411 forms a gap with the second trajectory segment 412 and the third trajectory segment 413 in the initial state. The bracket 42 has an opening 421 at the position corresponding to the first sub-gap 441; the elastic element 43 is partially embedded in the opening 421, and the structure of the opening 421 is as described above, so it will not be repeated here. One end of the first trajectory segment 411 passes through the first sub-gap 441 and is fixedly connected to the bracket 42, while the other end is suspended on the side of the second sub-gap 442 away from the bracket 42.

[0075] In one embodiment, such as Figure 2 , Figure 7 and Figure 8 As shown, the circuit board assembly 30 may include a circuit board 32 and a third housing 31. The third housing 31 is disposed between the first housing 10 and the second housing 20. The circuit board 32 includes a control circuit (not shown), which generates a first control signal based on the open or closed state between the first electrical region 331 and the second electrical region 332; and generates a second control signal based on the open or closed state between the third electrical region 333 and the fourth electrical region 334. Alternatively, the control circuit generates a third control signal by combining the open or closed state between the first electrical region 331 and the second electrical region 332 with the open or closed state between the third electrical region 333 and the fourth electrical region 334.

[0076] This can be understood as the control circuit controlling the disconnection or connection between the first electrical region 331 and the second electrical region 332, and the disconnection or connection between the third electrical region 333 and the fourth electrical region 334, respectively, so that the first electrical region 331 and the second electrical region 332 are connected to generate a first control signal, and the third electrical region 333 and the fourth electrical region 334 are connected to generate a second control signal; alternatively, the disconnection or connection between the first electrical region 331 and the second electrical region 332, and the disconnection or connection between the third electrical region 333 and the fourth electrical region 334 can be controlled simultaneously to generate a third control signal. The first electrical signal and the second electrical signal can each include one or more of the first control signal, the second control signal, and the third control signal, and the first control signal, the second control signal, and the third control signal can be set to corresponding different functions as needed, such as adjusting volume, liking, opening / closing an application, etc. Specific settings can be flexibly configured as needed, and this application does not impose any restrictions on this.

[0077] Please see Figure 12 , Figure 12 This is a schematic diagram of the circuit board provided in this application.

[0078] In one embodiment, such as Figure 12 As shown, the circuit board assembly 30 may further include a flexible substrate 301 and an electrical component 34 disposed on the flexible substrate 301. The flexible substrate 301 may serve as a circuit board 32, including a first surface 3211 and a second surface 3212 disposed opposite to each other. The first electrical region 331, the second electrical region 332, the third electrical region 333, and the fourth electrical region 334 are all electrically connected to the electrical component 34. The first electrical region 331, the second electrical region 332, the third electrical region 333, and the fourth electrical region 334 all include a conductive printed layer 33 disposed on the same layer as the first surface 3211. The flexible substrate 301 is configured to allow bending into an arc shape, and the first electrical region 331, the second electrical region 332, the third electrical region 333, and the fourth electrical region 334 are oriented toward the inner side of the arc shape, so that the electrical component 34 is oriented toward the outer side away from the second surface 3212.

[0079] The circuit board 32 fabricated on the flexible substrate 301 may further include a flexibly connected main body segment 321 and a bending segment 322. The surface of the main body segment 321 facing away from the third housing 31 is provided with a conductive printed layer 33, that is, the surface of the main body segment 321 facing the electrical trace assembly 40 has a conductive printed layer 33. The surface of the bending segment 322 facing away from the third housing 31 is provided with an electrical assembly 34. The conductive printed layer 33 and the electrical assembly 34 are electrically connected. The bending segment 322 is configured to allow bending relative to the main body segment 321 and to orient the electrical assembly 34 toward the side facing away from the conductive printed layer 33.

[0080] Specifically, the main body segment 321 has a first surface 3211 and a second surface 3212 disposed opposite to each other. A conductive printed layer 33 is disposed on the first surface 3211, and in the embodiment provided in this application, no components are disposed on the second surface 3212 of the main body segment 321. The bent segment 322 has a third surface 3223 and a fourth surface 3224. The electrical component 34 may be located on the third surface 3223 or the fourth surface 3224. In this embodiment, the electrical component 34 may be located on the third surface 3223, and no components are disposed on the fourth surface 3224. Furthermore, the second surface 3212 of the main body segment 321 and the fourth surface 3224 of the bent segment 322 are spaced apart and disposed opposite to each other.

[0081] In one embodiment, the main body segment 321 is flexible; or the main body segment 321 is rigid and arc-shaped. Specifically, the main body segment 321 and the bent segment 322 can be integrally formed by bending a flexible conductive material, or they can be made of a rigid material to form an arc-shaped main body segment 321 and a bent segment 322. The curvature of the main body segment 321 is greater than the curvature of the bent segment 322.

[0082] Specifically, such as Figure 4 As shown, the third housing 31 has a first notch 312; the main body segment 321 is arranged around the inner side of the third housing 31, and the bent segment 322 extends from the first notch 312 and is bent and then disposed on the outer side of the third housing 31, and is arranged at intervals and opposite to each other; or, the main body segment 321 is arranged around the outer side of the third housing 31, and the bent segment 322 extends into the first notch 312 and is bent and then disposed on the inner side of the third housing 31, and is arranged at intervals and opposite to each other. An electrical component 34 is disposed on the surface of the bent segment 322 away from the third housing 31. That is, the positions of the main body segment 321 and the bent segment 322 on the inner and outer sides of the third housing 31 can be interchanged as needed. The bent segment 322 can be bent from the inner side to the outer side relative to the third housing 31, or bent from the outer side to the inner side relative to the third housing 31, as long as the function of the circuit board 32 can be realized and it can be easily connected to the electrical component 34. This application does not limit its placement position and specific bending direction.

[0083] In a further embodiment, such as Figure 12As shown, the circuit board 32 may include a first bent section 3221 flexibly connected to one end of the main body section 321 and a second bent section 3222 flexibly connected to the other end of the main body section 321. The first bent section 3221 extends from one side of the first notch 312 and is bent and disposed on the outer side of the third housing 31; a first electrical device 341 is disposed on the surface of the first bent section 3221 facing away from the third housing 31. The second bent section 3222 extends from the other side of the first notch 312 and is bent and disposed on the outer side of the third housing 31; a second electrical device 342 is disposed on the surface of the second bent section 3222 facing away from the third housing 31. The first bent section 3221 and the second bent section 3222 may have the same structure and may be used to dispose of different electrical devices. The first electrical component 341 and the second electrical component 342 may include one or more of a main control chip, a drive circuit, a communication circuit, a capacitor, a resistor, or an inductor. The first electrical component 341 and the second electrical component 342 are evenly distributed on opposite sides of the main body segment 321, thereby balancing the weight distribution of the circuit board 32 and making the smart wearable device 100 weight-balanced. In other embodiments, other electrical components may be provided as needed, and this application does not impose any limitations on this.

[0084] Specifically, the main body segment 321 can be arranged around the inner side of the third housing 31; the first bent segment 3221 extends from one side of the first notch 312 and is bent and then disposed on the outer side of the third housing 31; the second bent segment 3222 extends from the other side of the first notch 312 and is bent and then disposed on the outer side of the third housing 31; or, the main body segment 321 is arranged around the outer side of the third housing 31; the first bent segment 3221 extends into the first notch 312 from one side and is bent and then disposed on the inner side of the third housing 31; the second bent segment 3222 extends into the first notch 312 from the other side and is bent and then disposed on the inner side of the third housing 31. The arrangement of the first bent segment 3221 and the second bent segment 3222 can refer to the aforementioned arrangement of the bent segment 322, and will not be repeated here. At the same time, the curvature of the main body segment 321 is greater than the curvature of the first bent segment 3221 and the second bent segment 3222.

[0085] In one embodiment, the central angle α between the two ends of the bent segment 322 is 20° to 60°, and the central angle β between the two ends of the outer periphery of the orthographic projection area of ​​the main body segment 321 is greater than 180°, that is, the arc of the main body segment 321 is a major arc. Specifically, it can be understood that the central angle α between the two ends of the first bent segment 3221 and the second bent segment 3222 is both 20° to 60°, for example, it can be 30°, 60°, etc.

[0086] In one embodiment, such as Figure 4As shown, the smart wearable device 100 may further include a battery 50, which is mounted around the projected area of ​​the main body segment 321 and the bent segment 322, and is arranged around the outer side of the third housing 31 and electrically connected to the circuit board 32; wherein, the battery 50 can be a toroidal battery. The battery 50 can be a disposable battery or a rechargeable battery. When the battery 50 is a rechargeable battery, it can be a wired rechargeable battery or a wireless rechargeable battery. A wired rechargeable battery is a battery that can be charged through a wired line, and a wireless rechargeable battery is a battery that can be charged through a wireless coil. The rechargeable battery 50 can also be used to support fast charging technology.

[0087] In one embodiment, the battery 50 has a second notch 501. It is understood that the opening size of the first notch 312 is smaller than the opening size of the second notch 501, so that the bent section 322 and the electrical component 34 are both located between the openings formed by the second notch 501, and both the first notch 312 and the bent section 322 can be exposed through the second notch 501.

[0088] In one embodiment, a sealing layer (not shown) arranged circumferentially is provided between the bracket 42 and the second housing 20. It can be understood that the sealing layer is sealed to the bracket 42 and the second housing 20 respectively; that is, sealing layers are provided on opposite sides of the bracket 42 and the second housing 20 in their respective axial directions, and the sealing layers extend relative to the circumferential arrangement of the bracket 42 and the second housing 20 to achieve sealing. The sealing layer can be a plastic sheet, or it can be formed by curing epoxy resin. It can be understood that the sealing layer, the bracket 42, and the second housing 20 together enclose a sealed space. Electrical components such as the circuit board assembly 30 and the electrical trace assembly 40 are located within the sealed space, which can effectively waterproof and seal the internal electrical components 34, reducing the risk of water entering and damaging the electrical components 34. In some embodiments, the sealing layer may also be located on opposite sides of the bracket 42 in the circumferential direction. Figure 3As shown, one end of the inner side of the second housing 20 has a second annular flange 311, and the other end of the outer side of the third housing 31 has a third annular flange 22. The second annular flange 311 and the third annular flange 22 are located at opposite ends of the battery 50 along the axial direction, thereby limiting the battery 50 and the bent section 322. In some embodiments, the second housing 20 and the third housing 31 are sealed together, for example, by means of the second annular flange 311 and the third annular flange 22. For example, sealing rings or adhesives can be used to seal the second annular flange 311 and the third annular flange 22 to the second housing 20 and the third housing 31 respectively, thereby providing waterproof protection for the battery 50 located inside. It can be understood that the second annular flange 311 and the third annular flange 22 can also be provided at opposite ends of the inner side of the second housing 20, or at opposite ends of the outer side of the third housing 31, which can also achieve the function of limiting the battery 50 and the bent section 322. In this embodiment, the second annular flange 311 is disposed at one end of the inner side of the second housing 20, and the third annular flange 22 is disposed at the other end of the outer side of the third housing 31, so as to facilitate direct sleeve installation of the circuit board 32 and avoid the problem of mutual interference and poor engagement of multiple annular components with a large arc shape during installation.

[0089] In one embodiment, such as Figures 2 to 3 As shown, the smart wearable device 100 may further include an annular cover plate 60, which is sleeved on one end of the outer side of the first housing 10. The other end of the outer side of the first housing 10 has a first annular flange 12. The first annular flange 12 and the annular cover plate 60 are used to limit the second housing 20 axially to prevent it from detaching axially. It can be understood that the first annular flange 12 and the annular cover plate 60 can also be integrally disposed at opposite ends of the outer side of the first housing 10 to achieve the purpose of limiting the second housing 20 axially. However, in the embodiment provided in this application, the annular cover plate 60 is separately disposed and separately installed from the first housing 10, thereby facilitating installation and disassembly. The annular cover plate 60 and the first housing 10 can be made of the same material, for example, both using insulating material.

[0090] Please see Figures 13 to 16 , Figure 13 yes Figure 3 The provided enlarged structural diagram of part A; Figure 14 yes Figure 13 An enlarged schematic diagram of the first structural form of part A' is provided; Figure 15 yes Figure 13 The provided enlarged schematic diagram of the second structure of part A'; Figure 16 This is a schematic diagram of the structure of the second housing and touch electrode provided in this application.

[0091] In the first structure, such as Figure 3 , Figure 13 As shown, the second housing 20 and the third housing 31 cooperate to form a rotating housing 70. The battery 50 is disposed inside the rotating housing 70, and the circuit board 32 is disposed on the third housing 31. Therefore, the circuit board 32 and the battery 50 can also rotate with the relative rotation of the second housing 20 and the third housing 31. The axial length of the rotating housing 70 is less than the distance between the first annular flange 12 and the annular cover plate 60, so as to form a fifth gap 81 between the first annular flange 12 and the annular cover plate 60, thereby facilitating the rotation of the rotating housing 70. Figure 14 As shown, ball bearings 25 can be further installed in both fifth gaps 81 to reduce friction and make rotation easier.

[0092] In the second structure, such as Figure 3 , Figure 15 As shown, one end of the rotating housing 70 has a first engaging portion 251, and the first annular flange 12 and / or the annular cover plate 60 has a second engaging portion 252 that engages with the first engaging portion 251. One of the first engaging portion 251 and the second engaging portion 252 is a protrusion or raised portion (not shown), and the other is a groove (not shown). The protrusion and the groove engage with each other to achieve the mating connection between the first engaging portion 251 and the second engaging portion 252. There are multiple first engaging portions 251 and second engaging portions 252, which are spaced apart circumferentially. During the rotation of the second housing 20 relative to the first housing 10, the engagement of the second engaging portion 252 with the first engaging portion 251 is periodically switched. For example, there is one first engaging part 251 and multiple second engaging parts 252. During the rotation of the second housing 20 relative to the first housing 10, since the first housing 10 does not rotate, the first engaging part 251 can switch from engaging with the current second engaging part 252 to engaging with the next second engaging part 252 every time the rotating housing 70 rotates, and so on.

[0093] In yet another embodiment, such as Figure 3 , Figure 16 As shown, multiple touch electrodes 21 can be disposed on the outer surface of the second housing 20. These touch electrodes 21 are spaced apart circumferentially along the second housing 20 and are electrically connected to the circuit board assembly 30. The circuit board assembly 30 can determine the rotation direction of the second housing 20 by the order in which the user touches the multiple touch electrodes 21. For example, the spacing between the multiple touch electrodes 21 can be different; when rotating clockwise, the distance between two adjacent touch electrodes 21 gradually increases; when rotating counterclockwise, the distance between two adjacent touch electrodes 21 gradually decreases. This method helps determine the rotation direction of the second housing 20, reducing the likelihood of accidental touches and improving touch accuracy.

[0094] In any of the above embodiments of this application, the first housing 10, the second housing 20, and the third housing 31 can all be annular, such as polygonal, circular, elliptical, etc., and in other embodiments, they can also be cuboid, etc. Specifically, the first housing 10, the second housing 20, and the third housing 31 can all be annular housings.

[0098] The processor 210 is used to execute the computer program stored in the memory 220 to implement the processing method of this application.

[0099] In some embodiments, the smart wearable device 100 may further include a peripheral device interface 230 and at least one peripheral device. The processor 210, memory 220, and peripheral device interface 230 can be connected via a bus or signal line.

[0105] In the several embodiments provided in this application, it should be understood that the disclosed smart wearable device 100 can be implemented in other ways. For example, the embodiments of the smart wearable device 100 described above are merely illustrative. For instance, the division of modules or units is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the coupling or direct coupling or communication connection shown or discussed may be an indirect coupling or communication connection through some interfaces, devices, or units, and may be electrical, mechanical, or other forms.

The smart wearable device disclosed in this application includes a first housing, a second housing, an electrical trajectory component, and a circuit board assembly; the second housing is sleeved on the outside of the first housing; wherein, the second housing can rotate relative to the first housing, thereby causing the electrical trajectory component and the circuit board assembly to cooperate in triggering a first electrical signal; and the second housing can move radially relative to the first housing, thereby causing the electrical trajectory component and the circuit board assembly to cooperate in triggering a second electrical signal. This application can realize the rotation and pressing operations of the second housing relative to the first housing, wherein the rotation and pressing operations can be performed separately or simultaneously to trigger different electrical signals, thereby completing different operation commands for the smart wearable device, resulting in convenient operation and high interaction efficiency. It can solve the problems of inconvenient operation and low interaction efficiency of existing smart wearable devices.

[0108] To address the aforementioned problems, this application also provides a method for operating a smart wearable device 100. Please refer to [link / reference]. Figure 19 , Figure 19 This is a flowchart illustrating the working method of the smart wearable device provided in this application.

[0109] The operating method of the smart wearable device 100 provided in this application can be applied to any of the smart wearable devices 100 described above. The smart wearable device 100 and the terminal device 300 are communicatively connected. The terminal device 300 may contain a controller 310, which is wirelessly connected to the control circuitry within the circuit board 32 of the smart wearable device 100. This allows the terminal device 300 to acquire information from the smart wearable device 100 and issue control commands to it. The terminal device 300 can be a mobile phone, computer, tablet, AR, VR, MR, or other head-mounted devices. Simultaneously, the smart wearable device 100 can interact with the external terminal device 300 through user interaction or related graphical interface functional interactions, such as swiping, page turning, confirmation, deletion, and other graphical interface operation functions.

[0110] The operation of the smart wearable device 100 may include the following steps:

[0111] S1: Obtain a first control signal for the second housing 20 to rotate relative to the first housing 10 to the first position D1.

[0112] In some embodiments, the first position D1 and the second position D2 are different positions in the circumferential direction. The second housing 20 can be rotated relative to the first housing 10 to the first position D1, that is, the first trajectory segment 411 is moved to the first position D1 and attached to the conductive printed layer 33, so that the first trajectory segment 411 can contact and conduct with the conductive printed layer 33 to generate a first control signal, which is then acquired by the processor 210 of the smart wearable device 100. The specific function of the first control signal can be set as needed.

[0113] In some embodiments, step S1 may also be: acquiring a first control signal generated by a first press of the first housing 10 relative to the second housing 20 at a first position D1. Specifically, the first position D1 and the second position D2 are different positions in the circumferential direction. Here, the first position D1 can be achieved by pressing the second housing 20 to switch the second housing 20 relative to the first housing 10 to the first position D1, and by bringing the second housing 20 radially closer to the first housing 10, so that the first trajectory segment 411 can contact and conduct with the conductive printed layer 33 to generate the first control signal, which is then acquired by the processor 210 of the smart ring 100. The specific function of the first control signal can be set as needed.

[0114] S2: Obtain a second control signal for the second housing 20 to rotate relative to the first housing 10 to the second position D2.

[0115] Specifically, the second housing 20 can be rotated relative to the first housing 10 to a second position D2, that is, the first trajectory segment 411 moves to connect only one of the first electrical region 331 and the second electrical region 332, or the first trajectory segment 411 moves to a position where it is not connected to either the first electrical region 331 or the second electrical region 332, so that the first electrical region 331 and the second electrical region cannot be connected and are in an open circuit state, thereby generating a second control signal. The second control signal is then obtained by the processor 210 of the smart wearable device 100. The specific function of the second control signal can be set as needed.

[0116] In some embodiments, step S2 may also be: acquiring a second control signal generated by a second press of the first housing 10 relative to the second housing 20 at a second position D2. Specifically, the second housing 20 is pressed a second time, where the second position D2 can be achieved by pressing the second housing 20 a second time, causing the second housing 20 to switch to the second position D2 relative to the first housing 10, and causing the second housing 20 to move radially away from the first housing 10, so that the first trajectory segment 411 does not contact the first electrical region 331 and the second electrical region 332, so that the first electrical region 331 and the second electrical region cannot be connected and are in an open circuit state, thereby generating a second control signal, which is then acquired by the processor 210 of the smart ring 100. The second control signal is different from the first control signal, and the specific function of the second control signal can be set as needed.

[0117] S3: Send a combination of the first control signal and the second control signal to the terminal device 300 and realize the interaction with the terminal device 300.

[0118] Specifically, after the processor 210 of the smart wearable device 100 obtains the first control signal and the second control signal, it can send the first control signal and the second control signal to the controller 310 of the terminal device 300 via wireless communication, thereby obtaining the control signal of the terminal device 300. It is understood that the first control signal and the second control signal are different, and their specific functions can be set as needed. It should be understood that the first press and the second press are only used to distinguish the different control signals generated by pressing the second housing 20, and the specific formation methods of the first press and the second press can be the same. For example, both can be pressing a certain point on the second housing 20, so that the second housing 20 moves closer or further away from the first housing 10 in the radial direction. It can be understood that the first press causes the second housing 20 to move relatively closer to the first housing 10 in the radial direction, so that the first trajectory segment 411 can contact and conduct with the conductive printed layer 33 to generate the first control signal; the second press causes the second housing 20 to move relatively further away from the first housing 10 in the radial direction, so that the first trajectory segment 411 does not contact and conduct with the conductive printed layer 33 to generate the second control signal.

[0119] It should be noted that the first control signal and the second control signal here can correspond to one of the first electrical signal and the second electrical signal, specifically to the electrical signal used for transmitting and receiving rotation function signals. This application does not impose any specific restrictions on this.
