Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] Please refer to the following first. Figure 1 The present invention provides a wearable device 1, which is worn on the human body to decorate and match the user's clothing or to be worn on the human body in conjunction with other devices, so that the user can view the time or measure the user's heart rate, number of steps, and other information, so as to facilitate the user to decorate and observe their own exercise status and health status.

[0033] The wearable device 1 includes a watch strap 10 and a watch face. The watch strap 10 is connected to the opposite ends of the watch face. The watch strap 10 and the watch face enclose a wearable cavity 11. A human body can pass through the wearable cavity 11 to wear the wearable device 1 on his / her body.

[0034] It should be noted that the watch face can be a smart watch face or a mechanical watch face, and the watch face also has functions such as displaying the time, making phone calls, remote video, and voice chat.

[0035] It should be noted that the wearable device 1 can be worn not only on the user's hand, but also on the user's waist and neck. The present invention does not specifically limit the specific wearing position of the wearable device 1.

[0036] refer to Figure 2 The watch strap 10 includes a first strap body 100, a second strap body 200, and a lever 300. The first strap body 100 and the second strap body 200 are respectively connected to opposite ends of the watch face. The lever 300 is connected to the first strap body 100 and can restrict the movement of the second strap body 200 relative to the first strap body 100, thereby fixing the size of the already adjusted wearable cavity 11 so that the user wears the wearable device 1 without it being too tight or too loose, resulting in a good user experience.

[0037] refer to Figure 2 The first belt 100 is provided with a gear 110, the axial direction of which is parallel to the thickness direction of the first belt 100. The lever 300 can selectively mesh with the gear 110. When the lever 300 meshes with the gear 110, the lever 300 restricts the movement of the second belt 200 relative to the first belt 100.

[0038] refer to Figure 2 It should be noted that the number of gears 110 is set to two, and the two gears 110 mesh with each other.

[0039] refer to Figure 2 The second strap 200 is provided with a rack 210 that meshes with the gear 110. The gear 110 meshes with different teeth 211 on the rack 210, allowing the gear 110 to move along the length of the rack 210, thereby moving the second strap 200 relative to the first strap 100 to adjust the size of the wearable cavity 11. The user can adjust the length of the strap 10 according to weather conditions or personal reasons.

[0040] It should be noted that the number of racks 210 is matched with the number of gears 110, for example... Figure 2 As shown, there are two gears 110 and two racks 210, with the two gears 110 meshing with the corresponding racks 210.

[0041] In summary, in this application, the watch strap 10 includes a first strap body 100 and a second strap body 200. The first strap body 100 is provided with a gear 110, the axial direction of which is parallel to the thickness direction of the first strap body 100. The second strap body 200 is provided with a rack 210 that meshes with the gear 110. The gear 110 can move along the length direction of the rack 210 to adjust the tightness of the watch strap 10. Furthermore, the axial direction of the gear 110 is parallel to the thickness direction of the first strap body 100, which makes the watch strap 10 thinner and provides a better user experience.

[0042] One of the first belt body 100 and the rack 210 is provided with a positioning post 120, and the other is provided with a sliding groove 212, for example... Figure 2 The diagram illustrates that the first belt body 100 is provided with a positioning post 120, and the rack 210 is provided with a sliding groove 212. The positioning post 120 is accommodated in the sliding groove 212, and the positioning post 120 can move along the sliding groove 212 until the positioning post 120 abuts against the side wall of the sliding groove 212. It should be noted that in other embodiments, the positions of the positioning post 120 and the sliding groove 212 can be reversed. In this case, the positioning post 120 is located on the rack 210, and the sliding groove 212 is located on the first belt body 100. It is understood that the positioning post 120 and the sliding groove 212 can also be omitted; any scheme in which the second belt body 200 can move relative to the first belt body 100 should be protected.

[0043] refer to Figure 2 It should be noted that the watch strap 10 also includes a mounting shaft 400, which passes through the gear 110 and connects to the first strap body 100. By providing the mounting shaft 400, the gear 110 is fixed to the first strap body 100. The gear 110 can rotate relative to the mounting shaft 400 and mesh with different tooth slots 211 of the corresponding rack 210. It is understood that the mounting shaft 400 can also be omitted; any solution that allows the gear 110 to be fixedly connected to the first strap body 100 should be protected.

[0044] refer to Figure 2 The watch strap 10 also includes a control component 500, which is connected to the first strap body 100 and the lever 300. The control component 500 can be manipulated and moved relative to the width of the first strap body 100, and can also drive the lever 300 to rotate relative to the first strap body 100. By setting the control component 500, the user can indirectly control the lever 300 by manipulating the control component 500. Furthermore, the movement of the control component 500 relative to the width of the first strap body 100 drives the lever 300 to rotate relative to the first strap body 100, eliminating the need for the user to directly or indirectly rotate the lever 300. This makes it easy for the user to operate the control component 500 and provides a good user experience. It is understood that the control component 500 can also be omitted; any scheme where the lever 300 can be manipulated and engaged with the gear 110 should be protected.

[0045] refer to Figure 2 The control component 500 includes a paddle 510 and an elastic element 520. The paddle 510 has a groove 511 at one end near the lever 300, and the lever 300 is accommodated within the groove 511. The opposite ends of the elastic element 520 are connected to the first belt 100 and the paddle 510, respectively. By setting the paddle 510 and the elastic element 520, the user operates the paddle 510 along the width direction of the first belt 100. The paddle 510 compresses the elastic element 520 to accumulate elastic force. When the user finishes operating the paddle 510 and releases it, the elastic force is released, and the elastic element 520 drives the paddle 510 back to its unoperated position. It is understood that if automatic reset of the paddle 510 is not considered, the paddle 510 and the elastic element 520 can be omitted; any scheme where the lever 300 can be operated and engaged with the gear 110 should be protected.

[0046] refer to Figure 1 It should be noted that the paddle 510 has a protrusion 512 on the side facing away from the lever 300, and the first belt body 100 has a moving groove 130. The protrusion 512 is accommodated within the moving groove 130 and can move within the moving groove 130. The moving groove 130 can limit the movement range of the paddle 510, so that when the user operates the paddle 510 or the elastic element 520 drives the paddle to reset, the paddle 510 will not disengage from the first belt body 100, and the paddle 510 can be precisely engaged with the gear 110. It can be understood that the protrusion 512 and the moving groove 130 can also be omitted, as long as the paddle 510 can move relative to the first belt body 100, this should be protected.

[0047] refer to Figure 2It should be noted that the paddle 510 has a positioning groove 513 on the side near the elastic member 520. The control assembly 500 also includes a positioning rod 530, which is accommodated in the positioning groove 513. The elastic member 520 is sleeved on the outside of the positioning rod 530. When the paddle 510 is operated, the paddle 510 moves along the positioning rod 530 and compresses the elastic member 520.

[0048] refer to Figure 3 and Figure 4 In another embodiment, the first belt body 100 includes at least two belt segments 140, each belt segment 140 being provided with a rotating shaft 141 and a slot 142, wherein the rotating shaft 141 of one belt segment 140 is detachably rotatably connected to the slot 142 of the other belt segment 140.

[0049] refer to Figure 3 and Figure 4 The granule 140 includes a first body 143, a first mounting block 144, a second mounting block 145, and a second body 146 connected in sequence. The two opposite ends of the rotating shaft 141 are respectively connected to the first body 143 and the second body 146. The first mounting block 144 and the second mounting block 145 are both recessed on the side away from the rotating shaft 141 to form a slot 142.

[0050] refer to Figure 3 and Figure 4 The strip 140 also includes a snap-fit ​​assembly 147 that extends into the slot 142 and is used to close or open the slot 142.

[0051] It should be noted that the first strap body 100 includes at least two strap links 140. The pivot 141 of the strap link 140 is detachably rotatably connected to the slot 142 of the other strap link 140, which enables quick adjustment of the length of the watch strap 10 and is easy to operate. The strap link 140 includes a first mounting block 144 and a second mounting block 145, which facilitates assembly and reduces costs.

[0052] It should be noted that if the first mounting block 144 and the second mounting block 145 are fixedly connected, the overall size of the snap-fit ​​assembly 147 is larger than the size of the slot 142, making it inconvenient to install the snap-fit ​​assembly 147 into the slot 142. By setting the first mounting block 144 and the second mounting block 145, the snap-fit ​​assembly 147 can be installed into the slot 142 first, and then the first mounting block 144 and the second mounting block 145 can be installed and fixed. Then, the fixed first mounting block 144 and the second mounting block 145 can be installed between the first main body 143 and the second main body 146, and the snap-fit ​​assembly 147 can be easily installed into the slot 142, facilitating assembly.

[0053] refer to Figure 4The first belt body 100 also includes a connecting shaft 150, which passes through the first mounting block 144 and connects to the second mounting block 145. By providing the connecting shaft 150, the first mounting block 144 and the second mounting block 145 are detachably connected. Compared to a fixed connection, this reduces processing and assembly difficulties, and lowers production costs. It is understood that the connecting shaft 150 can also be omitted; for example, the first mounting block 144 and the second mounting block 145 can be snap-fitted together. Any design in which the belt body 140 includes the first mounting block 144 and the second mounting block 145 should be protected.

[0054] refer to Figure 4 The connecting shaft 150 is a threaded branch 151, with its axially opposite ends threaded to the first mounting block 144 and the second mounting block 145, respectively. After the threaded branch 151 is threaded to the first mounting block 144 and the second mounting block 145, the fixed first mounting block 144 and the second mounting block 145 are then installed between the first body 143 and the second body 146 for easy installation. It is understood that the connecting shaft 150 can also be configured in other forms; any scheme where the connecting shaft 150 passes through the first mounting block 144 and connects to the second mounting block 145 should be protected.

[0055] refer to Figure 4 It should be noted that the number of connecting shafts 150 is set to two, and the two connecting shafts 150 are spaced apart along the length direction of the first mounting block 144. By setting two connecting shafts 150, the first mounting block 144 and the second mounting block 145 cannot rotate relative to each other, making the first mounting block 144 and the second mounting block 145 more securely installed. During daily wear, the first mounting block 144 and the second mounting block 145 will not rotate relative to each other, and the user does not need to frequently adjust the position between the first mounting block 144 and the second mounting block 145, thus extending the service life of the tassel 140. It is understood that the number of connecting shafts 150 can also be set to three or four; this invention does not specifically limit the number of connecting shafts 150.

[0056] refer to Figure 4Both the first mounting block 144 and the second mounting block 145 are provided with mounting grooves 148. The mounting grooves 148 are used to install the aforementioned snap-fit ​​assembly 147. The mounting grooves 148 are connected to the aforementioned snap-fit ​​groove 142. The snap-fit ​​assembly 147 includes a snap-fit ​​160 and a spring 161. Both the snap-fit ​​160 and the spring 161 are accommodated in the mounting groove 148. The spring 161 can drive the snap-fit ​​160 into the snap-fit ​​groove 142. The mounting groove 148 is provided with a protrusion 149 to prevent the snap-fit ​​160 from disengaging from the mounting groove 148. When the user operates the snap-fit ​​160, the snap-fit ​​160 compresses the spring 161 to accumulate elastic force. When the user installs the rotating shaft 141 of the adjacent sprocket 140 into the snap-fit ​​groove 142 and releases the snap-fit ​​160, the elastic force of the spring 161 is released. The spring 161 drives the snap-fit ​​160 to move along the length direction of the first mounting block 144 until the snap-fit ​​160 abuts against the protrusion 149. It is understandable that spring 161 may not be required, as long as the latch 160 can move relative to the first mounting block 144, it should be protected.

[0057] It should be noted that the spring 161 can also be set in other forms, such as torsion springs, coil springs and other elastic elements, or it can be set as a magnet with opposite magnetism. Any scheme that can drive the buckle 160 to move along the length direction of the first mounting block 144 should be protected.

[0058] refer to Figure 4 It should be noted that spring 161 includes a first spring 162 and a second spring 163. The opposite ends of the first spring 162 are connected to the buckle 160 and the first mounting block 144, respectively, and the opposite ends of the second spring 163 are connected to the buckle 160 and the second mounting block 145, respectively. By setting the first spring 162 and the second spring 163, the buckle 160 is subjected to more even force when it is manipulated to move along the length direction of the first mounting block 144. The first spring 162 and the second spring 163 will not break due to long-term uneven force, effectively extending the service life of the first spring 162 and the second spring 163. It can be understood that the first spring 162 and the second spring 163 can also be set to only one spring 161. Any scheme in which the spring 161 can drive the buckle 160 to move along the length direction of the first mounting block 144 should be protected.

[0059] refer to Figure 4The latch 160 is provided with an operating part 164 exposed on the first mounting block 144 and the second mounting block 145. The operating part 164 is used for manual operation to drive the latch 160 to move along the length direction of the first mounting block 144, thereby causing the latch 160 to disengage from the slot 142. By providing the operating part 164, which protrudes from the surface of the latch 160, the user can easily operate the operating part 164, making operation convenient and less strenuous. It can be understood that the operating part 164 can also be omitted; any solution that allows the user to operate the latch 160 should be protected.

[0060] refer to Figure 4 It should be noted that in this embodiment, the operating part 164 is a crescent-shaped groove, which is adapted to the shape of a human finger. It is understood that in other embodiments, the operating part 164 can also be set to other shapes, such as cylindrical or quadrangular prism. The present invention does not specifically limit the shape of the operating part 164.

[0061] refer to Figure 4 The first belt body 100 also includes a first fixed shaft 170 and a second fixed shaft 180. The opposite ends of the first fixed shaft 170 are respectively connected to the first mounting block 144 and the first main body 143, and the opposite ends of the second fixed shaft 180 are respectively connected to the second mounting block 145 and the second main body 146. The first fixed shaft 170 fixes the first mounting block 144 and the first main body 143, and the second fixed shaft 180 fixes the second mounting block 145 and the second main body 146. It is understood that the first fixed shaft 170 and the second fixed shaft 180 can also be omitted; any solution that allows the first mounting block 144 and the first main body 143 to be installed and fixed, and the second mounting block 145 and the second main body 146 to be installed and fixed, should be protected.

[0062] refer to Figure 4 It should be noted that the number of first fixed axes 170 is set to two, and the number of second fixed axes 180 is set to two.

[0063] It should be noted that the specific configuration of the second belt 200 is the same as that of the first belt 100, and the present invention will not elaborate on the specific configuration of the second belt 200.

[0064] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive.
