[0048] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.
[0049] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.
[0050] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0051] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0052] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0053] Reference Figures 1-10 As shown, according to one embodiment of the present application, a smart wearable device is provided, the smart wearable device comprising a device body 1, a connecting component 2 and a strap 3;
[0054] The connecting assembly 2 is mounted on the device body 1; the connecting assembly 2 includes a connecting shaft 21 and a first connecting body 22 fixedly connected to the connecting shaft 21, the connecting shaft 21 having a magnetic portion, and the connecting assembly 2 also includes a coil 23, the coil 23 being sleeved around the periphery of the magnetic portion; the watch strap 3 includes a second connecting body 300; the watch strap 3 is detachably connected to the device body 1 via the connecting assembly 2, and the watch strap 3 has a connected state and a released state;
[0055] Reference Figure 2 As shown, when the first connector 22 is connected to the second connector 300, the strap 3 is in a connected state; Figure 3 As shown, when the first connector 22 is detached from the second connector 300, the strap 3 is in a released state; when the strap 3 is in a connected state, the coil 23 is energized and the magnetic field direction of the coil 23 is opposite to the magnetic field direction of the magnetic part, the connecting shaft 21 moves and drives the first connector 22 away from the second connector 300, and the strap 3 switches from a connected state to a released state.
[0056] In the smart wearable device provided in the embodiment of the present application, the watch strap 3 is detachably connected to the device body 1 through the connecting component 2. The watch strap 3 can be removed from the device body 1 according to the user's needs.
[0057] Specifically, when the watchband 3 is in the connected state, that is, the watchband 3 is connected to the device body 1 via the connecting assembly 2, and the watchband 3 needs to be removed, the electronic control device of the smart wearable device supplies current to the coil 23, and controls the direction of the current so that the direction of the magnetic field of the coil 23 is opposite to the direction of the magnetic field of the magnetic portion of the connecting shaft 21. The coil 23 applies a magnetic field force to the magnetic portion of the connecting shaft 21. Specifically, the coil 23 and the magnetic portion repel each other, causing the connecting shaft 21, including the magnetic portion, to move as a whole. At the same time, the connecting shaft 21 drives the first connector 22 to move, so that the first connector 22 moves away from the second connector 300 and eventually detaches from the second connector 300. As a result, the watchband 3 switches from the connected state to the released state.
[0058] In summary, in the smart wearable device provided in the embodiment of the present application, the strap 3 is automatically released from the device body 1 by electric control, which is easy to operate and highly intelligent, thereby greatly improving the user experience.
[0059] Reference Figure 4 、 Figure 6 As shown, in one embodiment, the connecting assembly 2 includes an annular magnet 24 , which is fixedly sleeved on the periphery of the connecting shaft 21 , and the annular magnet 24 constitutes the magnetic portion of the connecting shaft 21 .
[0060] In this specific example, a ring magnet 24 is fixedly sleeved around the outer periphery of the connecting shaft 21 to form the magnetic portion of the connecting shaft 21. This simple and easy-to-manufacture method is used to form the magnetic portion. In other examples, the connecting shaft 21 can also be made of a magnetizable metal material, and then a portion of the connecting shaft 21 can be magnetized to form the magnetic portion.
[0061] Reference Figure 2 、 Figure 3 As shown, in one embodiment, when the first connector 22 is connected to the second connector 300, the arrangement direction of the first connector 22 and the second connector 300 is parallel to the axial direction of the connecting shaft 21; when the coil 23 is energized, the connecting shaft 21 moves along its axial direction and drives the first connector 22 away from the second connector 300.
[0062] In this specific example, the movement of the connecting shaft 21 caused by the coil 23 being energized is specifically movement along the axial direction of the connecting shaft 21; since the first connecting body 22 and the second connecting body 300 are arranged and connected along the axial direction of the connecting shaft 21, the movement of the connecting shaft 21 along the axial direction can drive the first connecting body 22 to move along the axial direction of the connecting shaft 21 and away from the second connecting body 300.
[0063] Reference Figure 2 、 Figure 3 As shown, in one embodiment, the connecting shaft 21 has a first end and a second end distributed along its axial direction. When the first connecting body 22 is connected to the second connecting body 300, the first connecting body 22 is arranged closer to the first end of the connecting shaft 21 relative to the second connecting body 300.
[0064] Reference Figure 4 As shown, for the magnetic part of the connecting shaft 21, its S pole is close to the first end of the connecting shaft 21, and the N pole is close to the second end of the connecting shaft 21; for the coil 23, when it is energized, its N pole is close to the first end of the connecting shaft 21, and the S pole is close to the second end of the connecting shaft 21.
[0065] In this specific example, by designing the arrangement direction of the first connecting body 22 and the second connecting body 300, the magnetic field direction of the magnetic part, and the magnetic field direction of the coil 23 when it is energized, it is ensured that when the coil 23 is energized, the connecting shaft 21 can drive the first connecting body 22 to move in a direction away from the second connecting body 300.
[0066] Specifically, according to Figure 2-Figure 4 In the direction shown, when the first connector 22 is connected to the second connector 300, the first connector 22 is located on the left side of the second connector 300; then, for the magnetic part of the connecting shaft 21, its S pole is located on the left side and the N pole is located on the right side; for the coil 23, when it is energized, its N pole is located on the left side and the S pole is located on the right side.
[0067] Reference Figure 5 As shown, in one embodiment, the device body 1 has a receiving space, and the connecting component 2 is installed in the receiving space; a power supply element 4 is also provided in the receiving space, and the coil 23 is electrically connected to the power supply element 4.
[0068] In this specific example, the coil 23 is energized by the power supply element 4, which further includes a battery 41 and a motherboard 42. The coil 23 is soldered to a solder point 421 on the motherboard 42 via a wire 231, while the battery 41 is fastened to a first connector 422 on the motherboard 42 via a first FPC 43.
[0069] Optionally, the device body 1 includes a box body 11 and a screen cover 12. The box body 11 has an opening, and the screen cover 12 covers the opening. The screen cover 12 is fastened to the second connector 423 of the mainboard 42 via a second FPC 44, so that the current flowing into the coil 23 can be controlled by clicking the operation panel of the screen cover 12.
[0070] Furthermore, the accommodating space includes a first accommodating slot 111 and a second accommodating slot 112 provided within the box body 11. Two first accommodating slots 111 are provided, one on either side of the second accommodating slot 112. The power supply element 4 is installed within the second accommodating slot 112, and the connecting assembly 2 is installed within the first accommodating slot 111. Because the smart wearable device includes two watch straps 3, two sets of connecting assemblies 2 are provided. That is, one set of connecting assemblies 2 is installed in each first accommodating slot 111, and each set of connecting assemblies 2 is connected to one watch strap 3.
[0071] Reference Figure 6 、 Figure 7 As shown, in one embodiment, the connecting assembly 2 includes a bracket base 20 , which is mounted on the device body 1 ; a slide 201 is formed on the bracket base 20 , and the connecting shaft 21 is movably disposed on the slide 201 .
[0072] In a specific example, the bracket base 20 is installed in the first receiving groove 111 of the device body 1; two first bosses are provided on the bracket base 20, and the slide 201 is opened on the two first bosses, and the extension direction of the slide 201 is consistent with the axial direction of the connecting shaft 21.
[0073] The two ends of the connecting shaft 21 are respectively arranged in two slideways 201; a cover plate 26 is connected to each first boss and the cover plate 26 is fixed by a cover plate screw 27. The setting of the cover plate 26 can ensure that the connecting shaft 21 will only move along its axial direction and will not move in other directions.
[0074] In addition, the coil 23 is fixedly wound on the coil support 28 , and the coil support 28 is mounted on the support base 20 via coil support screws 29 .
[0075] Reference Figure 7 、 Figure 8 As shown, in one embodiment, a first stop body 202 is formed on the bracket base 20, and the strap 3 includes an elastomer 31; when the strap 3 is in a connected state, the elastomer 31 abuts against the first stop body 202, and the first stop body 202 applies a first elastic force to the elastomer 31, and the direction of the first elastic force is to move the strap 3 away from the device body 1.
[0076] In this specific example, when the watchband 3 is in the connected state, the first stopper 202 abuts against the elastic member 31 provided on the watchband 3, elastically compressing the elastic member 31 and continuously applying a first elastic force to the elastic member 31. As a result, the watchband 3 is securely locked to the device body 1 without shaking. Furthermore, when the first connector 22 is disengaged from the second connector 300 and the watchband 3 switches to the released state, the first elastic force applied by the first stopper 202 to the elastic member 31 automatically ejects the watchband 3, completely detaching it from the device body 1. This makes detaching the watchband 3 more convenient and automated.
[0077] Reference Figure 2 、 Figure 3 and Figure 6 、 Figure 7 As shown, in one embodiment, the connecting assembly 2 further includes an elastic member 25, which is arranged at the end of the connecting shaft 21; a second stop body 203 is formed on the bracket base 20, one end of the elastic member 25 is connected to the end of the connecting shaft 21, and the other end of the elastic member 25 is connected to the second stop body 203; when the coil 23 is energized to move the connecting shaft 21, the elastic member 25 applies a second elastic force to the connecting shaft 21, and the direction of the second elastic force is opposite to the moving direction of the connecting shaft 21.
[0078] In this specific example, due to the elastic abutment between the second stopper 203 and the elastic member 25, once the watchband 3 is ejected and detached from the device body 1, the coil 23 is de-energized, and the elastic restoring force of the elastic member 25 causes the connecting shaft 21 to return to its original position, allowing the watchband 3 to be reattached to the device body 1 the next time. Optionally, the elastic member 25 is a return spring. It will be appreciated that even when the coil 23 is de-energized, control operations can still be performed by clicking the operation panel of the screen cover 12.
[0079] according to Figure 2 、 Figure 3 and Figure 6 In the direction shown, the elastic member 25 is arranged at the left end of the connecting shaft 21, and when the coil 23 is energized to drive the connecting shaft 21 to move, the connecting shaft 21 moves toward the left. In this case, the connecting shaft 21 squeezes the elastic member 25 toward the direction close to the second stop body 203, that is, the connecting shaft 21 applies an elastic pressure to the left on the elastic member 25, and at the same time, the elastic member 25 applies an elastic pressure to the right on the connecting shaft 21.
[0080] In other embodiments, the elastic member 25 can also be set at the right end of the connecting shaft 21, and accordingly, the second stop body 203 is also set on the right side of the bracket base 20; when the coil 23 is energized to drive the connecting shaft 21 to move, the connecting shaft 21 moves toward the left. In this case, the connecting shaft 21 pulls the elastic member 25 in the direction away from the second stop body 203, that is, the connecting shaft 21 applies an elastic pulling force to the left on the elastic member 25, and at the same time, the elastic member 25 applies an elastic pulling force to the right on the connecting shaft 21.
[0081] Reference Figure 6 、 Figure 8 、 Figure 9 As shown, in one embodiment, the first connector 22 includes a snap-in block 221; the strap 3 includes a strap body 30 and a buckle 32, the buckle 32 is arranged at the end of the strap body 30, and a slot is provided on the buckle 32, and the slot constitutes the second connector 300; when the snap-in block 221 is snapped into the slot, the strap 3 is in a connected state.
[0082] In a specific example, the watch strap 3 includes a strap body 30 and a buckle 32 connected to the end of the strap body 30. The buckle 32 includes a connecting plate 321 and connecting arms 322. Two connecting arms 322 are provided, one at each end of a first side of the connecting plate 321. Each connecting arm 322 has a slot, i.e., each connecting arm 322 has a second connector 300. Furthermore, the elastic body 31 is connected to the first side of the connecting plate 321 and is located between the two connecting arms 322. The second side of the connecting plate 321 is connected to the strap body 30. For example, a T-shaped clipping portion is provided on the second side of the connecting plate 321, and a T-shaped clipping slot is provided at the end of the strap body 30. The T-shaped clipping portion is clipped into the T-shaped clipping slot to achieve a detachable connection between the buckle 32 and the strap body 30.
[0083] Correspondingly, two first connecting bodies 22 are fixedly connected to the connecting shaft 21, and each first connecting body 22 includes: a transmission bracket 220, a clamping block 221 and a sliding shaft 222, wherein the transmission bracket 220 is fixedly connected to the connecting shaft 21, the clamping block 221 is used to cooperate with the slot (i.e., the second connecting body 300) opened on the buckle 32, and the sliding shaft 222 is used to be slidably connected to the bracket base 20; optionally, the transmission bracket 220, the clamping block 221 and the sliding shaft 222 are an integrally formed structure.
[0084] Furthermore, two second bosses and two third bosses are provided on the bracket base 20, wherein one of the second bosses cooperates with one of the third bosses and corresponds to one of the two first connectors 22; the other second boss cooperates with the other third boss and corresponds to the other of the two first connectors 22.
[0085] Furthermore, the second boss defines a first sliding hole 204 for the sliding shaft 222 to slide, and the third boss defines a second sliding hole 205 for the locking block 221 to slide.
[0086] Reference Figure 9 As shown, in one embodiment, the engaging block 221 has an inclined surface 2210 , and when the strap 3 switches from the released state to the connected state, the buckle 32 abuts against the inclined surface 2210 .
[0087] Further, refer to Figure 10 As shown, corresponding to any first receiving slot 111, the device body 1 is provided with a third sliding hole 101 and a fourth sliding hole 102. Two third sliding holes 101 are provided, one on each side of the fourth sliding hole 102. The third sliding hole 101 allows the connecting arm 322 of the buckle 32 to enter and exit the first receiving slot 111, while the fourth sliding hole 102 allows the elastic body 31 to enter and exit the first receiving slot 111.
[0088] In addition, a slide rail groove 206 is formed on the bracket base 20 for the connecting arm 322 to slide, and the position of the slide rail groove 206 corresponds to the third slide hole 101; it can be understood that the number of slide rail grooves 206 is also two, that is, the slide rail grooves 206 are set one-to-one with the third slide hole 101.
[0089] When the watch strap 3 is connected to the device body 1, the connecting arm 322 of the watch strap 3 slides into the slide rail groove 206 through the third sliding hole 101 and pushes the inclined surface 2210 of the clamping block 221. The inclined surface 2210 is subjected to force and decomposes the force F to produce a component force F1 along the axial direction of the connecting shaft 21. The component force F1 drives the clamping block 221 to move away from the connecting arm 322 along the axial direction of the connecting shaft 21, so that the connecting arm 322 slides smoothly in the slide rail groove 206. When the connecting arm 322 slides to the position where the clamping slot opened on it corresponds to the clamping block 221, the clamping block 221 enters the clamping slot, thereby completing the installation of the watch strap 3 on the device body 1.
[0090] According to another embodiment of the present application, a method for disassembling a watchband is provided. The watchband is the watchband 3 of the smart wearable device described above. The method for disassembling the watchband includes:
[0091] S101, when the watchband 3 is in a connected state, passing a current through the coil 23, wherein the direction of the current is such that the direction of the magnetic field of the coil 23 is opposite to the direction of the magnetic field of the magnetic part;
[0092] S102, the magnetic portion is subjected to the magnetic field force of the coil 23 and causes the connecting shaft 21 to move;
[0093] S103, the connecting shaft 21 drives the first connecting body 22 to move in a direction away from the second connecting body 300;
[0094] S104 , the first connector 22 is separated from the second connector 300 , and the strap 3 is switched from the connected state to the released state.
