Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a wearable device. Background Art

[0002] With the development of science and technology, more and more electronic devices are gradually pouring into people's lives. Among them, wearable devices are developing particularly rapidly and have become increasingly popular among consumers.

[0003] Wearable devices typically include a device body and a connecting strap, which is connected to the device body so that the device body can be worn on the user. Furthermore, wearable devices employ a separate adjustment mechanism to adjust the effective wearing length of the connecting strap to suit users of different body sizes and enhance wearing comfort. However, after adjustment, the stability of the connecting strap is poor, resulting in the effective wearing length of the connecting strap being easily changed, which in turn causes the wearable device to become loose. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a wearable device that can solve the problem of poor wearing stability of wearable devices in related technologies.

[0005] An embodiment of the present application provides a wearable device, comprising a device body, a connecting strap, and a locking mechanism, wherein:

[0006] The first end and the second end of the connecting belt are respectively connected to the device body, and at least one of the first end and the second end of the connecting belt is movable relative to the device body;

[0007] The locking mechanism includes a locking member and a toggle member. The locking member is arranged in the main body of the device and can be abutted against or separated from the first end or the second end of the connecting belt. The toggle member is connected to the locking member.

[0008] When the toggle member drives the locking member away from the connecting belt, the first end or the second end of the connecting belt can move relative to the device body; when the locking member abuts against the first end or the second end of the connecting belt, the locking member locks the first end or the second end of the connecting belt.

[0009] In an embodiment of the present application, the locking member can abut against the end of the connecting belt so that the locking member locks the position of the first end of the connecting belt or the position of the second end of the connecting belt. When the effective wearing length needs to be adjusted, the user applies an external force to the toggle member, and the external force drives the toggle member to move, and then the toggle member drives the locking member away from the connecting belt. At this time, the locking member no longer abuts against the connecting belt, and the locking member is separated from the first end or the second end of the connecting belt, that is, the locking mechanism unlocks the first end or the second end of the connecting belt, and the first end or the second end of the connecting belt can move relative to the device body to adjust the effective wearing length. After adjusting the effective wearing length, the user no longer applies external force to the toggle member, and the locking member loses the driving effect of the toggle member on it. The locking member can again abut against the first end or the second end of the connecting belt to fix the effective wearing length. Therefore, the wearable device of the present application locks or unlocks the position of the first end or the second end of the connecting belt through the locking mechanism, which can both adjust the effective wearing length of the connecting belt and fix the effective wearing length, thereby improving wearing stability and enhancing user experience.

[0037] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0038] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0039] The wearable device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] Please refer to Figures 1-14 The wearable device disclosed in the embodiment of the present application includes a device body 100, a connecting belt 200 and a locking mechanism 300, wherein the device body 100 serves as an installation base for the connecting belt 200 and the locking mechanism 300. Figure 1 As shown, the first end and the second end of the connecting belt 200 are respectively connected to the device body 100, so that the connecting belt 200 and the locking mechanism 300 together form a wearing space for accommodating the user's wearing part, and at least one of the first end and the second end of the connecting belt 200 can be moved relative to the device body 100 to adjust the size of the wearing space, that is, the first end of the connecting belt 200 is slidingly connected to the device body 100, and / or the second end of the connecting belt 200 is slidingly connected to the device body 100.

[0041] The locking mechanism 300 is used to lock the first end or the second end of the connecting belt 200 so that the first end or the second end of the connecting belt 200 is fixed relative to the device body 100. The locking mechanism 300 includes a locking member 310 and a toggle member 320. The locking member 310 is arranged in the device body 100. The locking member 310 can move relative to the device body 100, and the locking member 310 can be against or separated from the first end or the second end of the connecting belt 200. The toggle member 320 is connected to the locking member 310, and the toggle member 320 can drive the locking member 310 away from the first end or the second end of the connecting belt 200. Among them, the locking member 310 can be a block structure or a locking structure of other shapes. There is no limitation on the structure of the locking member 310 here. Figure 5 As shown, when the toggle member 320 drives the locking member 310 away from the connecting belt 200, the locking member 310 no longer applies abutting force to the first end or the second end of the connecting belt 200, and the first end or the second end of the connecting belt 200 can move relative to the device body 100, thereby adjusting the size of the wearing space; Figure 3 and Figure 4 As shown, when the locking member 310 abuts against the first end or the second end of the connecting belt 200, the locking member 310 locks the first end or the second end of the connecting belt 200. At this time, the toggle member 320 does not apply a driving force to the locking member 310, and the size of the wearing space remains fixed.

[0042] In an embodiment of the present application, the locking member 310 can be abutted against the end of the connecting belt 200 so that the locking member 310 locks the position of the first end of the connecting belt 200 or locks the position of the second end of the connecting belt 200. When the effective wearing length needs to be adjusted, the user applies an external force to the toggle member 320, and the external force drives the toggle member 320 to move, and then the toggle member 320 drives the locking member 310 away from the connecting belt 200. At this time, the locking member 310 no longer abuts against the connecting belt 200, and the locking member 310 is separated from the first end or the second end of the connecting belt 200, that is, the locking mechanism 300 unlocks the first end or the second end of the connecting belt 200, and the first end or the second end of the connecting belt 200 can move relative to the device body 100 to adjust the effective wearing length. After adjusting the effective wearing length, the user no longer applies external force to the toggle member 320, and the locking member 310 loses its driving effect. The locking member 310 can once again abut the first end or the second end of the connecting strap 200 to fix the effective wearing length. Therefore, the wearable device of the present application locks or unlocks the position of the first end or the second end of the connecting strap 200 through the locking mechanism 300, which can both adjust and fix the effective wearing length of the connecting strap 200, thereby improving wearing stability and enhancing user experience.

[0043] In an optional embodiment, as Figure 3-Figure 5As shown, the locking member 310 includes a first locking member 311 and a second locking member 312. The first locking member 311 and the second locking member 312 can jointly clamp the first end or the second end of the connecting belt 200. The toggle member 320 is connected to at least one of the first locking member 311 and the second locking member 312. The toggle member 320 can drive the first locking member 311 and the second locking member 312 away from each other. In this embodiment, the first locking member 311 and the second locking member 312 can both apply abutting force to the first end or the second end of the connecting belt 200 to jointly lock the first end or the second end of the connecting belt 200. The abutting force on the first end or the second end of the connecting belt 200 is increased, which helps to improve the stability of the first end or the second end of the connecting belt 200 in the locked state.

[0044] Of course, in other embodiments, the locking mechanism 300 may include a locking member 310, and the locking member 310 and the device body 100 may jointly clamp the first end or the second end of the connecting belt 200. When the locking member 310 is in contact with the connecting belt 200, the connecting belt 200 is also in contact with the device body 100.

[0045] In an optional embodiment, after adjusting the position of the first end or the second end of the connecting belt 200 relative to the device body 100, the locking member 310 can be pushed manually to allow the locking member 310 to re-align with the first end or the second end of the connecting belt 200. In another embodiment, the locking mechanism 300 further includes a first elastic member 330, wherein the first end of the first elastic member 330 is connected to the device body 100, and the second end of the first elastic member 330 is connected to the locking member 310. As the locking member 310 moves away from the connecting belt 200, the first elastic member 330 undergoes elastic deformation; after the locking member 310 loses the driving force of the toggle member 320, the first elastic member 330 resumes its elastic deformation and drives the locking member 310 to re-align with the first end or the second end of the connecting belt 200. The first elastic member 330 can be, but is not limited to, a spring. In this embodiment, the elastic force of the first elastic member 330 is used to directly drive the locking member 310 to abut against the first end or the second end of the connecting belt 200, without the need to manually drive the locking member 310 to reset, and the driving of the locking member 310 to reset is timely.

[0046] Optionally, the first elastic member 330 can be located on the side of the locking member 310 facing the connecting belt 200, and the first elastic member 330 is stretched when the locking member 310 moves away from the connecting belt 200; or, the first elastic member 330 can be located on the side of the locking member 310 facing away from the connecting belt 200, and the first elastic member 330 is compressed when the locking member 310 moves away from the connecting belt 200.

[0047] In an optional embodiment, the first elastic member 330 may be provided with one, or, as Figure 10 and Figure 11 As shown, there are at least two first elastic members 330, and each first elastic member 330 is spaced apart. In the latter embodiment, providing at least two first elastic members 330 can increase the elastic force and the number of points of action, which not only facilitates the timely reset of the locking member 310, but also helps increase the abutting force applied by the locking member 310 to the connecting belt 200, ensuring that the locking member 310 is stably locked. In the embodiment where the locking member 310 includes a first locking member 311 and a second locking member 312, at least two first elastic members 330 are provided on the side of the first locking member 311 facing away from the second locking member 312 and on the side of the second locking member 312 facing away from the first locking member 311. In this way, both the first locking member 311 and the second locking member 312 can be reset under the elastic action, avoiding manual actuation.

[0048] Of course, in other embodiments, such as Figure 12 As shown, the first elastic member 330 can be replaced by a magnetic member 360, and the first locking member 311 and the second locking member 312 are both provided with a magnetic member 360, and the magnetic member 360 provided on the first locking member 311 is opposite to the magnetic member 360 provided on the second locking member 312, that is, there is an attraction between the two. After the locking member 310 loses the driving force of the toggle member 320 on it, the first locking member 311 and the second locking member 312 are driven closer to each other by the attraction, so that the first locking member 311 and the second locking member 312 jointly clamp the first end or the second end of the connecting belt 200.

[0049] In an optional embodiment, after the toggle member 320 drives the locking member 310 away from the connecting band 200, the toggle member 320 can be reset by an external force. In another embodiment, the locking mechanism 300 also includes a second elastic member 340, the first end of the second elastic member 340 is connected to the device body 100, and the second end of the second elastic member 340 is connected to the toggle member 320. In the process of the toggle member 320 driving the locking member 310 away from the connecting band 200, the second elastic member 340 undergoes elastic deformation; after the toggle member 320 loses the external force, the second elastic member 340 recovers the elastic deformation to drive the toggle member 320 to reset. The second elastic member 340 can be, but is not limited to, a coil spring. With this embodiment, the elastic force of the second elastic member 340 is used to directly drive the toggle member 320 to reset in time, without relying on manual reset, saving manpower and being easy to use.

[0050] Alternatively, as Figure 14 As shown, the locking mechanism 300 further includes a housing 350, the housing 350 is provided with a rotating shaft 355, and the first end of the second elastic member 340 is connected to the rotating shaft 355, that is, the first end of the second elastic member 340 is indirectly connected to the device body 100 through the rotating shaft 355; Figure 13As shown, the toggle member 320 is provided with a positioning column 325 , and the second end of the second elastic member 340 is connected to the positioning column 325 , that is, the second end of the second elastic member 340 is indirectly connected to the toggle member 320 through the positioning column 325 .

[0051] In an optional embodiment, if Figure 13 As shown, the toggle member 320 can rotate relative to the device body 100, and the toggle member 320 includes a driving plate 323, and the driving plate 323 is provided with a driving surface 3231. The locking member 310 is provided with a transmission column 314, and the driving surface 3231 cooperates with the transmission column 314. When the toggle member 320 rotates, the transmission column 314 is driven to move through the driving surface 3231, and the locking member 310 moves along with the transmission column 314 along the direction of the rotation axis of the toggle member 320. Optionally, the toggle member 320 is provided with an axial hole that rotatably engages with the rotating shaft 355 of the housing 350, allowing the toggle member 320 to rotate about the rotating shaft 355, with the rotating axis of the toggle member 320 being the axis of the rotating shaft 355. A drive plate 323 is provided at the edge of the toggle member 320, facing the transmission post 314, and having an arc-shaped structure. The distance from the drive surface 3231 to the toggle member 320 increases or decreases along the circumference of the rotating shaft 355. In other words, the dimension of the drive plate 323 along the direction of the rotating axis of the toggle member 320 can be continuously varied, thereby applying a force to the toggle member 320. In this embodiment, the mating structure of the drive surface 3231 and the transmission post 314 allows the toggle member 320 to rotate, thereby driving the locking member 310 to move, thereby separating the locking member 310 from the connecting belt 200.

[0052] Of course, in other embodiments, the toggle member 320 can move relative to the device body 100, and the movement of the toggle member 320 directly drives the locking member 310 to move, thereby separating the locking member 310 from the first end or the second end of the connecting band 200. Relatively speaking, the toggle member 320 requires less space to move relative to the device body 100, thereby further reducing the space occupied by the wearable device.

[0053] In an embodiment where the locking member 310 includes a first locking member 311 and a second locking member 312, the toggle member 320 is positioned between the first locking member 311 and the second locking member 312. At least two drive plates 323 are provided, wherein the two drive plates 323 are respectively positioned on opposite sides of the toggle member 320. The two drive plates 323 engage with the transmission posts 314 of the first locking member 311 and the transmission posts 314 of the second locking member 312 via drive surfaces 3231. In this embodiment, when the toggle member 320 rotates, the drive plates 323 on its two sides drive the first locking member 311 and the second locking member 312 to move simultaneously. Therefore, the toggle member 320 only requires a small rotational displacement to create a large distance between the first locking member 311 and the second locking member 312, making it easier to achieve movement of the connecting belt 200 relative to the device body 100.

[0054] In an optional embodiment, the locking member 310 is directly disposed on the device body 100, and the toggle member 320 is directly movably connected to the device body 100, that is, the locking member 310 and the toggle member 320 are directly exposed. In another embodiment, the locking mechanism 300 further includes a housing 350, which is disposed on the device body 100, and the locking member 310 is disposed within the housing 350. The housing 350 is provided with a groove 351 and an opening 352 for the connecting belt 200 to pass through, and the connecting belt 200 can extend into the groove 351. The toggle member 320 is movably connected to the housing 350, and a portion of the toggle member 320 is located within the housing 350, while another portion of the toggle member 320 extends out of the housing 350 through the opening 352. Optionally, the first elastic member 330 is disposed within the housing 350, with a first end of the first elastic member 330 connected to the housing 350. A rotating shaft 355 is disposed within the housing 350, and the toggle member 320 is provided with an axial hole. The rotating shaft 355 rotatably engages with the axial hole, allowing the toggle member 320 to rotate about the rotating shaft 355. In this embodiment, the housing 350 protects the locking member 310 and the toggle member 320, preventing them from being exposed and damaged by collisions.

[0055] In an optional embodiment, the toggle member 320 only includes a driving portion 321, which is rotatably connected to the housing 350. A portion of the driving portion 321 is located inside the housing 350, and another portion of the driving portion 321 extends out of the housing 350 through the opening 352. In another embodiment, the toggle member 320 also includes a push

[0056] The rod 322 and the driving part 321 are located inside the housing 350. The first end of the push rod 322 is connected to the driving part 321, and the second end of the push rod 322 extends out of the housing 350 through the opening 352. External force can directly act on the push rod 322, and the driving part 321 is driven to rotate by pushing the push rod 322. In this embodiment, since the push rod 322 has a certain length, the power arm is increased when the external force acts on the push rod 322 compared to when the external force acts directly on the driving part 321, and it is more labor-saving when pushing the toggle member 320; in addition, the cross-sectional area of ​​the push rod 322 is small, so

[0057] Simply by providing a smaller opening 352, the second end of the push rod 322 can extend through the opening 352 and out of the housing 350. This improves the appearance, texture, and waterproof performance of the housing 350. Optionally, the drive portion 321 includes the aforementioned shaft hole, drive plate 323, and positioning post 325. The drive portion 321 and push rod 322 can be integrally formed, and the length of the push rod 322 can be perpendicular to the direction of the rotation axis of the toggle member 320.

[0058] In an optional embodiment, if Figure 8 As shown, the housing 350 is provided with a first limiting portion 353, and the toggle member 320 is provided with a second limiting portion 324. The first limiting portion 353 and the second limiting portion 324 cooperate to limit the movement direction of the toggle member 320. Optionally, the first limiting portion 353 and the second limiting portion 324 can be in contact with each other; the first limiting portion 353 and the second limiting portion 324 can both be limiting columns or limiting structures of other shapes, which are not limited in this embodiment of the present application. In this embodiment, the first limiting portion 353 and the second limiting portion 324 are used to limit the movement direction of the toggle member 320.

[0059] The second limiting portion 324 limits the position of the toggle member 320 to prevent excessive movement of the toggle member 320 under external force. Optionally, the first limiting portion 353 and the second limiting portion 324 cooperate to limit the rotation of the toggle member 320. There may be at least two first limiting portions 353, wherein the two first limiting portions 353 respectively cooperate with the second limiting portion 324 to limit the rotation in the first and second rotation directions, wherein the first rotation direction is opposite to the second rotation direction.

[0060] Of course, in other embodiments, the toggle member 320 may not be provided with the first limit portion 353, and the shell 3505 may not be provided with the second limit portion 324, and the movement amplitude of the toggle member 320 can be controlled by controlling the time and magnitude of the external force applied to the toggle member 320.

[0061] In an alternative embodiment, in combination with Figures 8-12 as well as Figure 14As shown, the toggle member 320 can drive the locking member 310 to move relative to the housing 350. One of the housing 350 and the locking member 310 is provided with a guide groove 354, and the other is provided with a protrusion 313. The guide groove 354 extends along the moving direction of the locking member 310, and the protrusion 313 is provided with a protrusion 313.

[0062] The guide groove 354 is slidably engaged. In this embodiment, the engaging structure of the protrusion 313 and the guide groove 354 is utilized to guide the movement direction of the locking member 310 relative to the housing 350, thereby preventing the locking member 310 from moving in an inappropriate direction.

[0063] Towards deviation.

[0064] Optionally, at least two guide grooves 354 and protrusions 313 may be provided at intervals, and each guide groove 354 corresponds to each protrusion 313. In this way, by using at least two guide grooves 354 and at least two protrusions 313,

[0065] The different positions of the locking member 310 are guided, thereby guiding the entire locking member 310 to ensure the overall stable movement of the locking member 310.

[0066] Of course, in other embodiments, the shell 350 and the locking member 310 may not be provided with the guide groove 354 and the protrusion 313, and the driving direction of the control member 320 is controlled to be consistent with the movement direction of the locking member 310, so that the locking member 310 is driven to move in a fixed direction through the toggle member 320.

[0067] In an optional embodiment, the locking mechanism 300 is provided with one, and the locking mechanism 300 locks the first end or the second end of the connecting belt 5200. In another embodiment, as Figure 1 As shown, the number of locking mechanisms 300

[0068] The number of locking mechanisms 300 is at least two, and the at least two locking mechanisms 300 include a first locking mechanism 301 and a second locking mechanism 302 spaced apart along the extending direction of the connecting belt 200. The first locking mechanism 301 and the second locking mechanism 302 are used to lock the first end and the second end of the connecting belt 200, respectively.

[0069] The locking mechanism 301 and the second locking mechanism 302 can respectively unlock or lock the first end and the second end of the connecting belt 200, so that the first end and the second end of the connecting belt 200 can move relative to the device body 100.

[0070] The position of the first end of the connecting belt 200 relative to the device body 100 can be adjusted, and the position of the second end of the connecting belt 200 relative to the device body 100 can also be adjusted, so as to adjust the size of the wearing space more quickly.
