[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The present application provides a wearable device 300, see Figures 1 to 4 , Figure 1 is a structural schematic diagram of an embodiment of a wearable device provided by the present application, Figure 2 yes Figure 1 The structure diagram of the strap of the wearable device shown is bent toward the side of the dial body, Figure 3 yes Figure 1 The structure diagram of the strap of the wearable device shown is bent toward the side away from the dial body, Figure 4 yes Figure 1 A schematic cross-sectional structure diagram of a strap of a wearable device is shown.

[0033] The wearable device 300 includes a dial body 200 and a strap 100, and at least one set of straps 100 is arranged at one end of the dial body 200. The dial body 200 may be a smart dial, which can display time, weather, send messages, make calls, etc.; the dial body 200 may also be a mechanical dial. The strap 100 can be automatically bent toward the dial body 200 to fit the dial body 200 and be worn on a human wrist.

[0034] For example, a set of straps 100 are connected to the dial body 200. After the wrist touches the dial body 200, the straps 100 automatically bend toward the dial body 200 to be clamped on both sides of the wrist with the dial body 200 respectively, so that the wearable device 300 can be automatically worn on the wrist, which is different from the traditional strap that needs to be manually buckled and adjusted.

[0035] Two sets of straps 100 can also be connected to the dial body 200, and the two sets of straps 100 are respectively connected to the opposite ends of the dial body 200. After the wrist touches the dial body 200, the two sets of straps 100 automatically bend toward the side where the dial body 200 is located, so that the two sets of straps 100 are clamped on both sides of the wrist to realize the automatic wearing function of the wearable device.

[0036] A contact sensor (not shown) may be provided on the side of the dial body 200 facing the wrist. The contact sensor is used to detect whether the dial body 200 matches a preset condition, and after detecting that the dial body matches the preset condition, send a signal to instruct the strap 100 to bend toward the dial body 200 so that the wearable device 300 can be worn on the wrist.

[0037] Among them, the preset condition can be that the dial body 200 is in contact with the wrist, the preset condition can also be that the distance between the dial body 200 and the wrist is less than a preset threshold, or the preset condition is that the pressure value between the dial body 200 and the wrist is greater than a preset threshold.

[0038] Optionally, the contact sensor is a photoelectric sensor, which emits light to the wrist and receives the emitted light, thereby determining whether the dial body 200 matches the preset conditions; the contact sensor can also be a pressure sensor, which detects the pressure when the dial body 200 contacts the wrist, and determines whether the dial body 200 matches the preset conditions based on the detected pressure value.

[0039] See also Figures 4 to 6 The watchband 100 generally includes a frame 10, a first traction member 20 and a driving member 30, wherein the driving member 30 drives the first traction member 20 to retract and extend, so as to drive the frame 10 to bend and stretch, thereby realizing the function of wearing and taking off the watchband 100.

[0040] The contact sensor is connected to the driving member 30 for communication, and when it detects that the dial body 200 matches the preset conditions, it sends a signal to the driving member 30 , and the driving member 30 contracts the first traction member 20 , so that the skeleton 10 bends toward the dial body 200 .

[0041] The frame 10 includes a base plate 12 and a plurality of first support blocks 14 disposed on one side of the base plate 12 . The plurality of first support blocks 14 are arranged side by side and at intervals along the base plate 12 . The first support blocks 14 are provided with first through holes 140 .

[0042] The first pulling member 20 is passed through the first through hole 140 , and the first pulling member 20 is used to drive the frame 10 to bend.

[0043] The driving member 30 is connected to the first traction member 20, and is used to retract the first traction member 20, thereby driving the multiple first support blocks 14 to tilt and move closer to each other, so that the substrate 12 bends toward the side where the first support block 14 is located. In other words, the skeleton 10 bends toward the side of the dial body 200, and then the skeleton 10 can cooperate with the dial body 200 to be clamped and worn on the wrist.

[0044] The driving member 30 is also used to relax the first traction member 20, so that the substrate 12 rebounds due to its own elasticity, so that the multiple first support blocks 14 move away from each other. In other words, the skeleton 10 rebounds and stretches and moves to the side away from the dial body 200, thereby loosening the wrist to facilitate the wearable device 300 to be taken off the wrist.

[0045] The driving member 30 rotates forward to contract the first traction member 20 , and rotates backward to relax the first traction member 20 . In other words, the driving member 30 can control the bending degree of the frame 10 to adapt to various wrist sizes.

[0046] The driving member 30 may be a motor; the driving member 30 may also be a cylinder and a transmission mechanism, the cylinder and the transmission mechanism are connected, the transmission mechanism can convert linear motion into circular motion, and then the cylinder drives the transmission mechanism to retract and release the first traction member 20.

[0047] The substrate 12 may be a flexible substrate, which is elastic as a whole, and can be bent by pulling the first support blocks 14 to tilt and move closer to each other. The substrate 12 may also be partially elastic, for example, the portion of the substrate 12 located between adjacent first support blocks 14 is elastic, while the portion of the substrate 12 corresponding to the first support blocks 14 is rigid.

[0048] The first traction member 20 may be a traction rope, a ligament, or a steel rope. One end of the first traction member 20 may be fixedly connected to the first support block 14 farthest from the driving member 30, and the other end of the first traction member 20 is connected to the rotating shaft of the driving member 30, so that the driving member 30 rotates forward to contract the first traction member 20, and the driving member 30 rotates backward to relax the first traction member 20. Alternatively, one end of the first traction member 20 is fixed to the dial body 200, and the plurality of first support blocks 14 are provided with two rows of first through holes 140, the first traction member 20 is arranged to pass through the two rows of first threading holes 140, and the other end of the traction member 30 is connected to the rotating shaft of the driving member 30.

[0049] In some embodiments, each first support block 14 is provided with a first through hole 140 , so that the first pulling member 20 is passed through each first through hole 140 .

[0050] In other embodiments, the first support block 14 may further be provided with a threading groove 142 , and the first support block 14 provided with the threading groove 142 and the first support block 14 provided with the first through hole 140 are spaced apart from each other, and the first traction member 20 is passed through the threading groove 142 and the first through hole 140 .

[0051] In this embodiment, the driving member 30 is disposed in the dial body 200, and one end of the skeleton 10 facing the driving member 30 is connected to the dial body 200. In other embodiments, the driving member 30 may also be disposed at one end of the skeleton 10 facing the dial body 200, and the skeleton 10 may also be connected to the dial body 200.

[0052] In this embodiment, the substrate 12 is further provided with a plurality of stress holes 120 to relieve bending stress generated by bending of the substrate 12 , so that the substrate 12 is easier to bend.

[0053] The stress hole 120 is arranged corresponding to the first support block 14 and is arranged in the middle of the substrate 12, and the stress hole 120 is connected to the first through hole 140, so that the connected stress hole 120 and the first through hole 140 can simultaneously relieve and release the bending stress on the first support block 14 and the substrate 12. The stress hole 120 can be arranged in a one-to-one correspondence with the first support block 14, and the stress hole 120 can also be arranged in correspondence with the spaced first support blocks 14.

[0054] In other embodiments, the stress hole 120 may not be arranged corresponding to the first support block 14 , and the present application does not limit this.

[0055] See also Figure 5 and Figure 7 In another embodiment, the skeleton 10 may further include a plurality of second support blocks 16 , which are disposed on a side of the substrate 12 away from the first support block 14 , and the plurality of second support blocks 16 are arranged side by side and at intervals along the substrate 12 , and the second support blocks 16 are provided with second through holes 160 .

[0056] The strap 100 further includes a second traction member 40 , and the second traction member 40 is passed through the second through hole 160 .

[0057] The driving member 30 is also connected to the second traction member 40. The driving member 30 is also used to contract the second traction member 40, thereby driving the multiple second support blocks 16 to tilt and move closer to each other, so that the substrate 12 is bent toward the side where the second support block 16 is located; the driving member 30 is also used to relax the second traction member 40, so that the bent substrate 12 rebounds, and the multiple second support blocks 16 move away from each other.

[0058] The driving member 30 contracts the first traction member 20, and the driving member 30 relaxes the second traction member 40; the driving member 30 contracts the second traction member 40, and the driving member 30 relaxes the first traction member 20. That is, the first traction member 20 and the second traction member 40 can be connected to the rotating shaft of the same driving member 30. When the driving member 30 rotates forward, the first traction member 20 is contracted, and the second traction member 40 is relaxed; when the driving member 30 rotates reversely, the first traction member 20 is relaxed, and the second traction member 40 is contracted, so that the driving member 30 can drive the frame 10 to bend to different sides.

[0059] The first traction member 20 and the second traction member 40 can also be connected to the rotating shaft of a driving member 30 respectively, wherein one driving member 30 contracts the first traction member 20 and the other driving member 30 relaxes the second traction member 40, wherein one driving member 30 relaxes the first traction member 20 and the other driving member 30 contracts the second traction member 40.

[0060] The first support block 14 and the second support block 16 are respectively disposed on two opposite sides of the base plate 12, so that the frame 10 can be bent toward opposite sides. Figure 3 and Figure 7 The substrate 12 is bent toward the side where the second support block 16 is located to increase the space between the frame 10 and the dial body 200, making it easier for the user to wear the wearable device 300 on the wrist. Figure 2 and Figure 7 The substrate 12 is bent toward the side where the first support block 14 is located, so that the frame 10 is tightened around the wrist to prevent the wearable device 300 from being separated from the wrist. Figure 3 and Figure 7 , the first traction member 20 is relaxed and the second traction member 40 is contracted, so that the substrate 12 is bent toward the side where the second support block 16 is located, and then the wearable device 300 is detached from the wrist.

[0061] In this embodiment, the first traction member 20 and the second traction member 40 are elastic traction members such as ligaments, so as to prevent the first traction member 20 and the second traction member 40 from restraining each other during the retraction and extension process.

[0062] The second support blocks 16 can be disposed in a one-to-one correspondence with the first support blocks 14 , or can be disposed in a corresponding correspondence with the spaced first support blocks 14 , which is not limited in the present application.

[0063] A threading groove may also be provided on the second support block 16 , and the second traction member 40 is also passed through the threading groove and the second through hole 160 , which is not limited in the present application.

[0064] The heights of the first support block 14 and the second support block 16 relative to the substrate 12 decrease gradually from the end close to the driving member 30 to the end away from the driving member 30. The distances from each first through hole 140 to the corresponding end of the first support block 14 away from the substrate 12 are the same, and the distances from each second through hole 160 to the corresponding end of the second support block 16 away from the substrate 12 are the same.

[0065] The top surfaces of the first support blocks 14 facing away from the base plate 12 are in the same plane, and since the first support blocks 14 decrease in sequence, the base plate 12 is inclined relative to the plane, and the distances from the first through holes 140 to the plane are equal, so when the first pulling member 20 pulls the first support block 14, the base plate 12 is easy to bend toward the side where the first support block 14 is located. Similarly, the above arrangement also makes it easy for the base plate 12 to bend toward the side where the second support block 16 is located.

[0066] Furthermore, the plurality of first support blocks 14 and the plurality of second support blocks 16 are symmetrically arranged with respect to the substrate 12 , so that the substrate 12 has the same ability to bend toward both sides.

[0067] See also Figure 6 and Fig. 9 The skeleton 10 further includes a connection seat 18, which is used to connect to the dial body 200. The connection seat 50 can be fixedly connected to the dial body 200 by bonding, snapping or screwing.

[0068] In this embodiment, the connection seat 18 is disposed at one end of the base plate 12 facing the driving member 30, wherein a positioning groove 180 is provided on the side of the connection seat 18 away from the first support block 14, a buckle groove 182 is provided on the side of the connection seat 18 away from the base plate 12, and a connection hole 184 is provided on the side of the connection seat 18 away from the buckle groove 182, and the connection hole 184 is connected to the positioning groove 180. The positioning groove 180 and the buckle groove 182 are both connected to the dial body 200, so as to match the position of the calibration skeleton 10 relative to the dial body 200, and then a fastener is used to fix it to the dial body 200 through the connection hole 184.

[0069] See also Figure 5The strap 100 further includes a sensor 50, which is disposed on the frame 10 and is used to detect the tightness of the strap 100. The sensor 50 is in communication with the driving member 30 and sends a signal to stop the driving member 30 from contracting the first traction member 20 after the strap 100 reaches an appropriate tightness, thereby preventing the strap 100 from being too tight and injuring the wrist.

[0070] Among them, the sensor 50 and the contact sensor can be different types of sensors or the same type of sensors, and the present application does not limit this. The sensor 50 can be a pressure sensor, which detects the pressure between the frame 10 and the wrist to identify the tightness of the strap 100. The sensor 50 can also be a distance sensor, which detects the distance between the frame 10 and the wrist to identify the tightness of the strap 100. The sensor 50 can also be an infrared sensor, etc., and the present application does not limit this.

[0071] See also Figure 5 and Figure 8 The watchband 100 further includes a protective cover 60, which includes a cover body 62 and an extension 64. The extension 64 is disposed at one end of the cover body 62, and an opening 620 is disposed at the other end of the cover body 62. The cover body 62 is sleeved on the frame 10 from the opening 620 to cover the entire frame 10. Since the protective cover 60 is elastic, the wearing comfort of the watchband 100 can be increased. The extension 64 disposed at one end of the cover body 62 can also increase the length of the watchband 100, so that the bending degree of the frame 10 can be relatively small to allow the watchband 100 to be tightened on the wrist.

[0072] See also Fig. 9 A mounting plate 70 is also sleeved on the connecting seat 18, and the mounting plate 70 is stopped on the side of the connecting seat 18 away from the first supporting block 14. The sleeve 62 is sleeved on the frame 10 from the opening 620, and the end of the sleeve 62 with the opening 620 is fixedly connected to the mounting plate 70, thereby ensuring that the protective cover 60 does not separate from the frame 10.

[0073] Different from the prior art, the present application discloses a wearable device and a watch strap thereof. The present application provides a skeleton including a substrate and a plurality of first support blocks, provides a first traction member penetrating a first through hole of the first support block, and provides a driving member to contract the first traction member, thereby driving the plurality of first support blocks to tilt and approach each other, so that the substrate is bent toward the side where the first support block is located, and the driving member also relaxes the first traction member, so that the bent substrate rebounds, and the plurality of first support blocks move away from each other, thereby realizing automatic tightening and loosening of the watch strap. Therefore, the watch strap provided by the present application can be automatically tightened and loosened, and manual buckling of the watch strap is avoided.

[0074] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
