DETAILED DESCRIPTION

[0046] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" refers to two or more than two.

[0047] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0048] like Figures 1 to 7As shown, an embodiment of the present invention provides a smart wearable device, including a device body 100 and a strap group; the strap group includes a first strap 200, a second strap 300 and a locking mechanism 400 connecting the first strap 200 and the second strap 300; both ends of the strap group are respectively connected to both sides of the device body 100; a main circuit board 110 is arranged inside the device body 100, the first strap 200 and / or the second strap 300 are provided with a flexible circuit board 500, and the first strap 200 and / or the second strap 300 are connected to the device body 100 through a connector 600 to electrically connect the flexible circuit board 500 and the main circuit board 110; the locking mechanism 400 is signal-connected to the main circuit board 110.

[0049] In the above-mentioned smart wearable device, when worn, the device body 100 is electrically connected to the strap set through the connector 600, and the first strap 200 and the second strap 300 in the strap set are connected and locked by the locking mechanism 400. When the smart wearable device is disconnected from the device body 100 and the strap set and removed, the flexible circuit board 500 is disconnected from the main circuit board 110, and the purpose of anti-disassembly can be achieved by giving an early warning prompt or an alarm light on the device body 100. When the smart wearable device needs to be disconnected from the first strap 200 and the second strap 300 and removed, it is necessary to obtain authorization first, such as entering a password from the device body, and the main circuit board 110 drives the locking mechanism 400 to unlock. Therefore, the smart wearable device provided in the embodiment of the present invention cannot be removed without authorization after being worn, and after being removed, the guardian can receive the removal information in time, thereby achieving the purpose of anti-disassembly.

[0050] In one possible implementation, a flexible circuit board 500 is provided in the first strap 200, a main circuit board 110 is provided in the device body 100, and the flexible circuit board 500 in the first strap 200 is electrically connected to the main circuit board 110 in the device body 100 through a connector 600. When the connection between the first strap 200 and the device body 100 is disconnected, the main circuit board 110 cannot receive the current on the flexible circuit board 500, and it is determined that the smart wearable device is removed. The information that the smart wearable device is removed can be displayed on the screen of the device body 100 or directly sent to a mobile terminal bound to the smart wearable device, such as a smart phone or a tablet computer, to implement a disassembly reminder or disassembly alarm of the first strap 200 and the device body 100.

[0051] In one possible implementation, a flexible circuit board 500 is provided in the second strap 300, a main circuit board 110 is provided in the device body 100, and the flexible circuit board 500 in the second strap 300 is electrically connected to the main circuit board 110 in the device body 100 through a connector 600. When the connection between the second strap 300 and the device body 100 is disconnected, the main circuit board 110 cannot receive the current on the flexible circuit board 500, and it is determined that the smart wearable device is removed. The information that the smart wearable device is removed can be displayed on the screen of the device body 100 or directly sent to a mobile terminal bound to the smart wearable device, such as a smart phone or a tablet computer, to implement a disassembly reminder or disassembly alarm of the second strap 300 and the device body 100.

[0052] In one possible implementation, the first strap 200 and the second strap 300 are both provided with a flexible circuit board 500, the device body 100 is provided with a main circuit board 110, and the flexible circuit board 500 in the first strap 200 is electrically connected to the main circuit board 110 in the device body 100 through a set of connectors 600, and the flexible circuit board 500 in the second strap 300 is electrically connected to the main circuit board 110 in the device body 100 through another set of connectors 600. Thus, a disassembly reminder or disassembly alarm is realized between the entire strap set and the device body 100.

[0053] In a possible implementation, the first strap 200 and the second strap 300 are connected and locked by a locking mechanism 400, and the locking mechanism 400 is connected to the main circuit board 110 by signal. Specifically, the locking mechanism 400 can be connected to the main circuit board 110 by signal through the flexible circuit board 500 on the first strap 200 or the flexible circuit board 500 on the second strap 300. The unlocking of the locking mechanism 400 requires the main circuit board 110 to send an unlock command to open. Exemplarily, the main circuit board 110 sends an unlock command to the locking mechanism 400 by entering a password on the smart wearable device or authorizing unlocking on the corresponding software on the mobile terminal bound to the smart wearable device, such as a smart phone or a tablet computer. Therefore, the smart wearable device can be unlocked only after authorization.

[0054] It is understandable that if only one strap in the strap group is provided with a flexible circuit board 500, the other strap can be connected with other anti-disassembly structures, such as the strap and the device body 100 are an integrated structure, etc., so as to achieve the effect of anti-disassembly everywhere in the entire smart wearable device.

[0055] It should be noted that if both the first strap 200 and the second strap 300 are provided with a flexible circuit board electrically connected to the main circuit board 110, the strap itself can also be protected from violent disassembly. For example, when the strap is violently cut, the main circuit board 110 can issue an alarm command.

[0056] In some embodiments, the connector 600 includes a first connecting terminal 610 and a second connecting terminal 620, the first connecting terminal 610 is arranged at the end of the first strap 200 and / or the second strap 300, and is electrically connected to the flexible circuit board 500 inside the first strap 200 and / or the second strap 300; the second connecting terminal 620 is arranged on the device body 100, and is electrically connected to the main circuit board 110 inside the device body 100; a positioning groove 101 allowing the first connecting terminal 610 to be inserted is provided on the device body 100; the second connecting terminal 620 passes through the bottom wall of the positioning groove 101.

[0057] One possible way to achieve this is as follows: Figure 1 and Figure 2 As shown, for the sake of convenience, only the connection between the first strap 200 provided with a flexible circuit board 500 and the device body 100 is used as an example for explanation, which should not be understood as a limitation on the connection between the second strap 300 and the device body 100. The first strap 200 is provided with a flexible circuit board 500, and a first connection terminal 610 is convexly provided at the connection end between the first strap 200 and the device body 100. A positioning groove 101 is formed at the connection end between the device body 100 and the first strap 200. The second connection terminal 620 is located inside the mobile device body 100, and passes through the positioning groove 101 and is inserted into the internal space of the positioning groove 101. The second connection terminal 620 is a metal movable part such as a special-shaped spring pin (pogopin).

[0058] It is understandable that the circuit between the main circuit board 110 and the flexible circuit board 500 needs to form a loop, so the first strap 200 and the device body 100 are electrically connected through two groups of connectors 600. And the two groups of connectors 600 can adopt the same structure.

[0059] Obviously, such as Figure 1 As shown, the first connection terminal 610 has a limiting groove, so the first connection terminal 610 is also used for the mechanical connection between the first strap 200 and the device body 100. Exemplarily, a limiting mechanism is provided inside the device body 100, and when the first connection terminal 610 on the first strap 200 is inserted into the positioning groove 101 of the device body 100, the limiting mechanism inside the device body 100 slides into the limiting groove on the first connection terminal 610, and the first strap 200 is limited and locked, thereby realizing the mechanical connection between the first strap 200 and the device body 100.

[0060] One possible way to achieve this is as follows: Figure 3 As shown, two opposite ends of the device body 100, namely, the two ends respectively connected to the first strap 200 and the second strap 300, are provided with two sets of second connection terminals 620, and each set of second connection terminals 620 is two spring pins arranged at intervals. The specific structure of the spring pins can be as follows Figure 4 shown.

[0061] In some embodiments, a first seal 120 is provided between the first strap 200 and / or the second strap 300 and the device body 100, for sealing the positioning groove 101 when the strap assembly is connected to the device body 100; and / or a second seal is provided between the second connecting terminal 620 and the device body 100.

[0062] One possible way to achieve this is as follows: Figure 2 As shown, the connection end of the device body 100 and the strap set is provided with a first seal 120 to prevent external moisture and dust from entering the device body 100 through the gap between the strap set and the device body 100 through the positioning groove 101 to damage the internal electronic components. Exemplarily, the surface of one end of the device body 100 contains two-color injection-molded liquid silicone or post-assembled foam or silicone ring, which plays a sealing and waterproof effect when the strap is assembled with the device body 100.

[0063] One possible way to achieve this is as follows: Figure 5 As shown, the housing of the device body 100 is provided with a glue dispensing groove 102 around the spring pin and on one side of the inner wall, which is used for dispensing glue to form a second sealing member to achieve the glue dispensing sealing and waterproofing of the spring pin. Figure 5 The first strap 200 and / or the second strap 300 are formed by injection molding a special-shaped spring pin into the housing of the device body 100, and the movable end of the spring pin extends into the positioning groove 101 at one end of the device body 100, and is pressed together with the first connecting terminal 610 of the first strap 200 and / or the second strap 300 to form a passage, and the other end of the spring pin is elastically connected to the spring sheet on the main circuit board 110 (such as PCBA, Printed Cicrcuit Board Assembly) to form a passage.

[0064] In some embodiments, the locking mechanism 400 is disposed on the first strap 200, and a flexible circuit board 500 is disposed in the first strap 200; a strap slot 310 cooperating with the locking mechanism 400 is disposed on the second strap 300; the locking mechanism 400 includes a fixed shell 410 and a button switch 420, a locking member, a limit assembly 440 and a driving assembly 450 installed inside the fixed shell 410, the driving assembly 450 is transmission-connected to the limit assembly 440 for locking and unlocking the button switch 420, and when the button switch 420 is in an unlocked state, the button switch 420 can drive the locking member to insert into or withdraw from the strap slot 310; the driving assembly 450 is electrically connected to the main circuit board 110 inside the device body 100 through the flexible circuit board 500 in the first strap 200 through the connector 600.

[0065] In one possible implementation, the locking mechanism 400 is disposed on the first strap 200, and the second strap 300 is provided with a strap groove 310 that cooperates with the locking mechanism 400. The fixed housing 410 of the locking mechanism 400 can be connected to the first strap 200, or can be an integral structure with the first strap 200, such as an integral structure by injection molding. Of course, part of the fixed housing 410 can also be an integral structure with the first strap 200, such as the fixed housing 410 adopts a splicing structure of a bottom shell and a top shell, wherein the bottom shell and the first strap 200 are an integral structure. Figure 6-Figure 13 As shown, in order to conveniently show the structure inside the fixed housing 410, the fixed housing 410 is omitted. The fixed housing 410 is provided with a key switch 420, a locking member, a limit assembly 440 and a drive assembly 450. The locking member can be connected to the key switch 420 in a transmission manner or can be an integrated structure with the key switch 420. Figure 8 and Fig. 9 As shown, the locking member and the key switch 420 are an integrated structure, or it can be said that the key switch 420 is provided with a locking column 421 that cooperates with the strap groove 310. The key switch 420 has a locked state and an unlocked state. When the key switch 420 is in the locked state, the key switch 420 cannot be triggered. Fig.11 As shown, the key switch 420 cannot be lifted; when the key switch 420 is in the unlocked state, the key switch 420 can be triggered, such as Fig.13 As shown, by pressing the key switch 420, the locking column 421 can be inserted into the strap slot 310, and the key switch 420 can also be lifted. It can be understood that in order to facilitate triggering the key switch 420, a pressing window that cooperates with the pressing part of the key body is provided on the fixed housing 410. The drive assembly 450 is connected to the main circuit board 110 inside the device body 100 by signal so as to receive the unlocking command.

[0066] In some embodiments, the button switch 420 is limited by a concave-convex structure. Specifically, the limit assembly 440 includes a limit block 442, and the button switch 420 is provided with a limit groove 441 that cooperates with the limit block 442; the driving assembly 450 is transmission-connected to the limit block 442, and is used to drive the limit block 442 to insert or withdraw from the limit groove 441 to lock or unlock the button switch 420.

[0067] In some embodiments, the driving assembly 450 includes a motor 451 and a first slider 452 . The motor 451 is electrically connected to the flexible circuit board 500 in the first strap 200 . The motor 451 is transmission-connected to the limit block 442 via the first slider 452 .

[0068] One possible way to achieve this is as follows: Fig.11 and Fig.13As shown, the key switch 420 is provided with a limit slot 441 through which a limit block 442 passes, and the limit block 442 has a clamping portion 442a that cooperates with the limit slot 441. Exemplarily, a T-slot is provided on the key switch 420, and the main body of the limit block 442 corresponds to the vertical slot area of ​​the T-slot, and the limit portion of the limit block 442 corresponds to the horizontal slot area of ​​the T-slot. The motor 451 drives the main body of the limit block 442 to move along a surface perpendicular to the T-slot through the first slider 452 to lock or unlock the key switch 420. It is understandable that the motor 451 drives the first slider 452 to move linearly, which can be achieved through a lead screw slider structure. Exemplarily, a driving external thread is provided on the output shaft of the motor 451, and a threaded hole that cooperates with the driving external thread is provided on the first slider 452; or, the motor 451 is connected to the first slider 452 through a lead screw.

[0069] In some embodiments, the locking mechanism 400 further includes a first elastic member 460 , which is used to always provide the push switch 420 with a force to drive the locking member to exit the strap slot 310 .

[0070] In one possible implementation, when the key switch 420 is unlocked, it can be lifted to allow the locking column 421 to exit the strap slot 310, which is convenient for adjusting the size of the ring structure of the smart wearable device. By providing a first elastic member 460, when the key switch 420 is unlocked by the limit assembly 440 and the drive mechanism, it is automatically lifted under the action of the first elastic member 460, which is convenient for adjusting the length of the strap set. Exemplarily, the first elastic member 460 is a spring.

[0071] In some embodiments, the driving assembly 450 further includes a second elastic member 470 , and the second elastic member 470 is used to always provide a force for the limiting block 442 to be inserted into the limiting groove 441 .

[0072] One possible way to achieve this is as follows: Fig.11 and Fig.13 As shown, the first slider 452 and the limit block 442 are connected by contact, that is, when the motor 451 drives the first slider 452 to move forward, the first slider 452 pushes the main body of the limit block 442 to move backward, and the clamping portion 442a of the limit block 442 slides out of the limit slot 441, and the button can be lifted. When the motor 451 drives the first slider 452 to move backward, the first slider 452 cannot drive the main body of the limit block 442 to move forward. At this time, the locking mechanism 400 also includes a second elastic member 470. Under the action of the second elastic member 470, the limit block 442 automatically moves forward until the clamping portion 442a is inserted into the limit slot 441. Exemplarily, the second elastic member 470 is a spring.

[0073] It should be noted that the first elastic member 460 and the second elastic member 470 are both mounted on the fixed housing 410, that is, one end of the first elastic member 460 is connected to the fixed housing 410, and the other end is connected to the key cap of the key body (not shown in the figure); one end of the second elastic member 470 is connected to the fixed housing 410, and the other end is connected to the main body of the limit block 442, such as Fig.14 shown.

[0074] One possible implementation method is Fig.11 and Fig.13 As shown, the first slider 452 and the motor 451 are respectively located on both sides of the key switch 420 , so the threaded lead screw or the output shaft of the motor 451 passes through the limiting groove 441 . Fig.11 The clamping portion 442a of the middle limit clamping block 442 is located in the transverse groove area of ​​the T-shaped groove, and the key body compresses the first elastic member 460 but cannot be lifted, and the first elastic member 460 stores elastic potential energy; Fig.13 The engaging portion 442a of the middle engaging block withdraws from the transverse groove area of ​​the T-shaped groove, and the first elastic member 460 releases elastic potential energy to lift up the key body.

[0075] like Figure 6-Figure 14As shown, when the smart wearable device provided by this embodiment is worn, the key switch 420 is pressed, and the bottom locking column 421 is inserted into the strap groove 310. At this time, the first elastic member 460 is in a compressed state, locking the strap, and the limit card block 442 is automatically inserted into the limit groove 441 of the key switch 420 by the elastic force of the second elastic member 470. At this time, the second elastic member 470 of the limit card block 442 is in a pop-up state, locking the key switch 420, preventing the key switch 420 from bouncing upward under the action of the first elastic member 460, thereby locking the strap. When the limit card block 442 is not subjected to external force, it is affected by the rear second elastic member 470, and the clamping portion 442a will not withdraw from the limit groove 441 of the key switch 420, so the strap cannot be opened. When the watch strap needs to be opened, only by sending an unlocking command to the motor 451 through the main circuit board 110, the motor 451 pushes the limit block 442 backward through the first slider 452, and the clamping portion 442a of the limit block 442 withdraws from the limit slot 441 of the key switch 420. At this time, the second elastic member 470 of the limit block 442 is in a compressed state, and the key switch 420 is not blocked by the clamping portion 442a of the limit block 442. It automatically pops up due to the elastic force of the first elastic member 460, and the locking column 421 withdraws from the watch strap slot 310, and the watch strap is loosened. The size of the limit slot 441 on the key switch 420 is smaller than the lateral size of the limit block 442 as a whole (mainly the part connected to the second elastic member 470), which can prevent the limit block 442 from moving, and the motor 451 can be reset. When the watch strap needs to be locked again, one only needs to manually adjust the length of the watch strap to the corresponding position and press the button switch 420 to lock the watch strap. When the limit groove 441 of the button switch 420 and the clamping portion 442a of the limit clamp block 442 are aligned, the limit clamp block 442 is automatically inserted into the limit groove 441 under the influence of the elastic force of the second elastic member 470 to lock the button switch 420. At this time, the watch strap is locked.

[0076] In some embodiments, the locking member is a paddle 431 rotatably installed inside the fixed shell 410 through a rotating shaft 432, and the paddle 431 has a pressing end and a locking end; a pressing window adapted to the push button switch 420 is provided on the fixed shell 410, and the push button switch 420 is transmission-connected to the pressing end; the locking mechanism 400 also includes a third elastic member 480, and the third elastic member 480 is used to always provide the paddle 431 with a force to rotate around the rotating shaft 432 so that the locking end can exit the strap slot 310.

[0077] One possible implementation method is Figure 15-Figure 21As shown, the locking mechanism 400 is provided on the first strap 200, and the second strap 300 is provided with a strap groove 310 that cooperates with the locking mechanism 400. The fixed housing 410 of the locking mechanism 400 can be connected to the first strap 200, or it can be an integral structure with the first strap 200, such as an integral structure by injection molding. Of course, part of the fixed housing 410 can also be an integral structure with the first strap 200, such as the fixed housing 410 adopts a splicing structure of a bottom shell and a top shell, wherein the bottom shell and the first strap 200 are an integral structure. Figure 15-Figure 20 As shown, in order to conveniently show the structure inside the fixed housing 410, the fixed housing 410 is omitted. A key switch 420, a locking member, a limit assembly 440 and a drive assembly 450 are arranged inside the fixed housing 410. The locking member can be transmission-connected to the key switch 420. An exemplary locking member is a paddle 431, which is rotatably mounted on two opposite side walls of the fixed housing 410 via a rotating shaft 432. The key switch 420 has an unlocked state and a locked state. When the key switch 420 is in the unlocked state, the key switch 420 can be triggered, such as Fig.18 As shown, by pressing the button switch 420, the button switch 420 presses the pressing end of the paddle 431, thereby lifting the locking end of the paddle 431 to unlock the first strap 200 and the second strap 300; when the button switch 420 is in the locked state, the button switch 420 cannot be triggered, such as Fig.19 As shown, the key switch 420 cannot be pressed. It is understandable that, in order to facilitate triggering the key switch 420, a pressing window that cooperates with the pressing portion of the key body is provided on the fixed housing 410. When the key switch 420 is pressed, under the action of the third elastic member 480, the paddle 431 rotates in the opposite direction around the rotating shaft 432, and the pressing end of the paddle 431 lifts the key switch 420. Exemplarily, the third elastic member 480 is a torsion spring.

[0078] It should be noted that the third elastic member 480 is installed on the fixed housing 410. Fig.21 As shown, the second elastic member 470 is a torsion spring, and both legs of the torsion spring are connected to the fixed housing 410 .

[0079] In some embodiments, the limiting assembly 440 includes a second slider 443, a U-shaped slot 443A is provided on the second slider 443, a T-shaped block 422 is provided on the key switch 420, and the plane where the U-shaped slot 443A is located is perpendicular to the plane where the T-shaped block 422 is located; the driving assembly 450 is transmission connected to the second slider 443, and is used to drive the second slider 443 to approach the key switch 420 along the opening direction of the U-shaped slot 443A so that the T-shaped block 422 is limited in the U-shaped slot 443A to lock the key switch 420, and is also used to drive the second slider 443 away from the key switch 420 along the opening direction away from the U-shaped slot 443A to unlock the key switch 420.

[0080] One possible implementation method is Fig.18 and Fig. 20 As shown, the key switch 420 and the second slider 443 are limited by the U-shaped slot 443A and the T-shaped block 422. Specifically, the U-shaped slot 443A can be formed by a rectangular ring structure with a notch, wherein the size of the notch is smaller than the length of the side of the rectangular ring where the notch is located, such as Fig. 20 As shown, two side edges adjacent to the side edge where the notch is set are provided with avoidance grooves for avoiding the lateral portion of the T-shaped block 422, as shown in FIG. Fig.18 shown. Fig.18 The middle button switch 420 is in the unlocked state, and the T-shaped block 422 of the button switch 420 is exactly located in the area where the avoidance groove is located and can be pressed. The driving component 450 drives the second slider 443 to move forward, such as Fig. 20 As shown, the lateral portion of the T-shaped block 422 in the key switch 420 is limited by the side wall of the U-shaped slot 443A, so that the key switch 420 cannot be pressed.

[0081] In some embodiments, the driving assembly 450 includes a motor 451, which is electrically connected to the flexible circuit board 500 in the first strap 200; the motor 451 is transmission-connected to the second slider 443 for driving the second slider 443 to move linearly.

[0082] It can be understood that the motor 451 drives the second slider 443 to move linearly, which can be achieved through a screw slider structure. For example, a driving external thread is provided on the output shaft of the motor 451, and a threaded hole matching the driving external thread is provided on the second slider 443; or, the motor 451 is connected to the second slider 443 through a screw.

[0083] like Figure 15-Figure 20As shown, the smart wearable device provided in this embodiment can directly pull the second strap 300 when adjusting the strap length. The paddle 431 of the second strap 300 slides along the strap groove 310. A rotating shaft 432 is provided in the middle of the paddle 431. Torsion springs are installed at both ends of the rotating shaft 432 to apply elastic force to the paddle 431, so that the locking end of the paddle 431 is always buckled to the strap groove 310 to lock the second strap 300. When the second strap 300 needs to be loosened, the key switch 420 is pressed. Through the principle of lever, the locking end of the paddle 431 is tilted and separated from the strap groove 310, and the second strap 300 can be withdrawn backward. Of course, the adjustment of the strap length is operated when the key switch 420 is in the unlocked state. When the second strap 300 is not allowed to be disassembled, a locking instruction is sent to the motor 451 through the main circuit board 110, and the motor 451 drives the second slider 443 to move forward, and the second slider 443 blocks the key switch 420. At this time, the button switch 420 cannot press the trigger paddle 431, and the second strap 300 cannot be released. When unlocking is required, the main circuit board 110 sends an unlocking command to the motor 451, and the motor 451 drives the second slider 443 to move backward, so that the avoidance groove on the second slider 443 is aligned with the button switch 420, and the on / off button can be pressed normally to release the second strap 300, and the second strap 300 is in a freely adjustable state.

[0084] The smart wearable device provided by the embodiment of the present invention can realize anti-disassembly between the straps and the adjustable length of the straps; it can also realize the anti-violent damage of the straps and the damage can be known; it can also realize intelligent disassembly between the straps after authorization, and non-removal without authorization.

[0085] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
