Description

Technical Field

[0001] This application belongs to the field of wearable device structural design technology, and specifically relates to a wearable device. Background Technology

[0002] As wearable devices become increasingly widely used, various electronics manufacturers have launched a variety of wearable electronic devices, such as smartwatches, smart glasses, and smart clothing, to cater to market demand. Taking smartwatches as an example, they not only have timekeeping functions but also offer features like calling, video recording, health management, and activity tracking, making them popular with users of all ages.

[0003] Currently, most wearable devices on the market use buckles to connect the straps to the main body of the device. However, because the head of the strap has internal structures such as buckles, buttons, and springs, the head of the strap is quite thick, which reduces the fit between the strap and the skin when the wearable device is being worn. Utility Model Content

[0004] The purpose of this application is to provide a wearable device that can solve the problem of the excessive thickness of the head of the connecting strap in current wearable devices.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a wearable device, including a device body, a connecting strap, and a connecting assembly for connecting the device body and the connecting strap. The device body has a mounting groove, and the head of the connecting strap can be inserted into the mounting groove. The head has a limiting structure. At least a portion of the connecting assembly is disposed in the mounting groove. The connecting assembly is rotatably connected to the device body to allow the connecting assembly to engage or disengage with the limiting structure.

[0007] When the wearable device is in a first state, the connecting component engages with the limiting structure to connect the connecting strap to the device body; when the wearable device is in a second state, the connecting component disengages from the limiting structure to detach the connecting strap from the device body.

[0008] In this embodiment, when the connecting strap needs to be connected to the device body, the connecting component is first driven to rotate, then the head of the connecting strap is inserted into the mounting slot of the device body, and then the connecting component is driven to rotate in the opposite direction, so that the connecting component and the limiting structure of the head of the connecting strap are limited and engaged, thereby connecting the connecting strap to the device body; when the connecting strap needs to be disassembled from the device body, the connecting component is first driven to rotate, so that the connecting component and the limiting structure are disengaged, then the head of the connecting strap is pulled out from the mounting slot, and then the connecting component is driven to rotate in the opposite direction to reset.

[0009] Compared to the buckle connection in the prior art, this application sets the connection method between the head of the wearable device's connecting strap and the device body to a plug-in method and uses a limiting fit method for connection. This avoids setting buckles, buttons, springs and other structures in the head of the connecting strap, thereby reducing the thickness of the head of the connecting strap and improving the fit between the connecting strap and the skin when the wearable device is in the wearing state.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The wearable device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] like Figures 1 to 10As shown in the figure, this application discloses a wearable device. Optionally, the wearable device can be a smartwatch, smart glasses, etc., and this application does not impose specific limitations on it.

[0027] The wearable device includes a main body 100, a connecting strap 200, and a connecting component 300 for connecting the main body 100 and the connecting strap 200. The main body 100 has a mounting groove 110, optionally with the opening of the mounting groove 110 facing the connecting strap 200. The head 210 of the connecting strap 200 can be inserted into the mounting groove 110, and the head 210 has a limiting structure. At least a portion of the connecting component 300 is disposed in the mounting groove 110. The connecting component 300 is rotatably connected to the main body 100 so that the connecting component 300 is engaged with or disengaged from the limiting structure. When the wearable device is in a first state, i.e., when the wearable device is in a wearable state, the connecting component 300 is engaged with the limiting structure to connect the connecting strap 200 to the main body 100. When the wearable device is in a second state, i.e., when the wearable device is in a non-wearable state, the connecting component 300 is disengaged from the limiting structure to separate the connecting strap 200 from the main body 100.

[0028] In this embodiment, when the connecting strap 200 needs to be connected to the device body 100, the connecting component 300 is first driven to rotate, then the head 210 of the connecting strap 200 is inserted into the mounting groove 110 of the device body 100, and then the connecting component 300 is driven to rotate in the opposite direction, so that the connecting component 300 and the limiting structure of the head 210 of the connecting strap 200 are limited and engaged, thereby connecting the connecting strap 200 to the device body 100; when the connecting strap 200 needs to be disassembled from the device body 100, the connecting component 300 is first driven to rotate, so that the connecting component 300 and the limiting structure are disengaged, then the head 210 of the connecting strap 200 is pulled out from the mounting groove 110, and then the connecting component 300 is driven to rotate in the opposite direction to reset. Compared to the snap-fit ​​connection in existing technologies, this application uses a plug-in connection method between the head 210 of the wearable device's connecting strap 200 and the device body 100, employing a limiting fit. This avoids the need for snap-fit ​​structures, buttons, springs, etc., within the head 210 of the connecting strap 200, thereby reducing the thickness of the head 210 and improving the fit between the connecting strap 200 and the skin when the wearable device is worn. Therefore, this application solves the problem of the excessive thickness of the head 210 of the connecting strap 200 in current wearable devices.

[0029] Optionally, the limiting structure can be a limiting groove; or, in other optional embodiments, the limiting structure is a limiting hole 211, both ends of which extend to opposite sides of the head 210 of the connecting band 200 in the width direction of the connecting band 200. The head 210 is also provided with a clearance opening 212 communicating with the limiting hole 211. The clearance opening 212 extends along the insertion direction of the head 210 so that a portion of the connecting component 300 passes through the clearance opening 212 and extends into the limiting hole 211. The width of the limiting hole 211 is greater than the width of the clearance opening 212. During the process of inserting the head 210 of the connecting strap 200 into the mounting slot 110 of the equipment body 100, the head 210 enters the mounting slot 110 from the insertion interface and gradually approaches the connecting component 300. When the head 210 is further inserted, part of the connecting component 300 enters the clearance opening 212. When the connecting component 300 enters the limiting hole 211, the insertion movement of the head 210 stops. Then, the connecting component 300 is driven to rotate in the opposite direction so that the connecting component 300 is limited and engaged with the limiting hole 211. At this time, part of the connecting component 300 is wrapped by the head 210 of the connecting strap 200, which helps to increase the contact area between the connecting component 300 and the limiting hole 211, thereby improving the connection stability between the connecting strap 200 and the equipment body 100.

[0030] Optionally, the end of the clearance opening 212 away from the limiting hole 211 is chamfered to provide a guiding function for the connecting component 300, so as to facilitate the insertion of the connecting component 300 into the clearance opening 212.

[0031] In an optional embodiment, the connecting assembly 300 includes a limiting rod 310, with both ends of the limiting rod 310 rotatably connected to the opposite side walls of the mounting groove 110. In this case, one end of the limiting rod 310 can extend through the side wall of the mounting groove 110 to outside the equipment body 100. By driving the end of the limiting rod 310, the limiting rod 310 can rotate relative to the equipment body 100, thereby allowing the limiting rod 310 to engage or disengage with the limiting hole 211. Alternatively, the connecting assembly 300 may also include an elastic drive... The moving part 320 and the elastic driving part 320 can drive the limiting rod 310 to rotate relative to the main body 100, so that the limiting rod 310 is engaged or disengaged from the limiting hole 211. At this time, the limiting rod 310 is driven to rotate by the elastic driving part 320, which can save driving force. Furthermore, when the limiting rod 310 needs to rotate in the opposite direction, the user can release the elastic driving part 320 and use the elastic potential energy of the elastic driving part 320 itself to drive the limiting rod 310 to rotate in the opposite direction. At the same time, the elastic driving part 320 restores its deformation.

[0032] In a further optional embodiment, the device body 100 has a first surface 120 in its thickness direction, the mounting groove 110 extends to the first surface 120, the head 210 has a second surface 213 in its thickness direction, the second surface 213 is flush with the first surface 120, the head 210 also has a first clearance notch 214 and a second clearance notch 215, both of the first clearance notch 214 and the second clearance notch 215 are connected to the clearance opening 212 and extend to opposite sides of the head 210 in its thickness direction, respectively, and the device body 100 also has a mounting hole 130 connected to the mounting groove 110, spring The driving component 320 is a rod-shaped structure. The elastic driving component 320 includes a first elastic segment 321 and a second elastic segment 322 connected together. The first elastic segment 321 slides with the wall of the mounting hole 130 through a first clearance notch 214. The limiting rod 310 is provided with a through hole. The limiting rod 310 is sleeved on the second elastic segment 322 through the through hole. The end of the second elastic segment 322 away from the first elastic segment 321 passes through the second clearance notch 215 and protrudes from the second surface 213. The second elastic segment 322 can rotate relative to the first elastic segment 321 to drive the limiting rod 310 to be limited or disengaged from the limiting hole 211.

[0033] When the limiting rod 310 needs to rotate, the second elastic segment 322 is driven away from the end of the first elastic segment 321, causing the second elastic segment 322 to rotate relative to the first elastic segment 321. This rotates the limiting rod 310, allowing it to engage or disengage with the limiting hole 211. Simultaneously, the first elastic segment 321 slides against the wall of the mounting hole 130. This solution uses the aforementioned elastic drive component 320, which has a relatively long lever arm, thus saving driving force. Of course, the aforementioned elastic drive component 320 can also be replaced with a torsion spring or other elastic structure.

[0034] Optionally, the wearable device also includes a back cover 400, which covers the first surface 120 of the device body 100 to protect the circuit board and other structures disposed within the receiving cavity of the device body 100.

[0035] Optionally, the opening of the mounting hole 130 is chamfered to provide a guide for the first elastic segment 321, so as to facilitate the insertion of the first elastic segment 321 into the mounting hole 130.

[0036] Optionally, the mounting hole 130 may communicate with the receiving cavity of the equipment body 100, and a portion of the first elastic segment 321 may extend into the receiving cavity of the equipment body 100.

[0037] Optionally, the side wall of the mounting groove 110 is provided with a first limiting groove 111, which is opposite to the insertion interface of the mounting groove 110 and extends to the first surface 120. The end of the second elastic segment 322 away from the first elastic segment 321 can be limited and engaged with the first limiting groove 111. Before inserting the head 210 of the connecting strap 200 into the mounting groove 110, the second elastic segment 322 needs to be driven closer to the first elastic segment 321 so that the limiting rod 310 can pass through the clearance opening 212 of the head 210 and enter the limiting hole 211; or, when it is necessary to release the limiting engagement between the limiting rod 310 and the limiting hole 211, the second elastic segment 322 needs to be driven closer to the first elastic segment 321 so that the limiting rod 310 is released from the limiting hole 211, so that the limiting rod 310 can pass through the clearance opening 212 of the head 210 and thus pull the head 210 out of the mounting groove 110. Therefore, in the above embodiment, during the rotation of the second elastic segment 322 relative to the first elastic segment 321, the first limiting groove 111 can prevent the second elastic segment 322 from continuing to rotate, thus avoiding damage due to excessive rotation angle. Of course, the first limiting groove 111 can also be omitted, and the side wall of the mounting groove 110 can be used directly for limiting.

[0038] And / or, in other optional embodiments, a second limiting groove 215a is provided at the second clearance notch 215, the second limiting groove 215a extends to the second surface 213, and the end of the second elastic segment 322 away from the first elastic segment 321 can be limited and engaged with the second limiting groove 215a. When the limiting rod 310 is located in the limiting hole 211, the second elastic segment 322 rotates in the opposite direction to the first elastic segment 321, and the elastic drive member 320 gradually recovers its deformation. When the second elastic segment 322 rotates to be limited and engaged with the second limiting groove 215a, the second limiting groove 215a prevents the second elastic segment 322 from continuing to rotate, so that the limiting rod 310 and the limiting hole 211 are more stably limited and engaged, thereby improving the connection stability between the connecting belt 200 and the equipment body 100. Of course, the second limiting groove 215a can also be omitted, and the side wall of the second clearance notch 215 can be used directly for limiting.

[0039] In another optional embodiment, the connecting assembly 300 further includes a handle 330 connected to the limiting rod 310. The handle 330 has a receiving hole that communicates with a through hole. The end of the second elastic segment 322 away from the first elastic segment 321 extends through the through hole into the receiving hole. The free end of the handle 330 passes through the second clearance notch 215 and protrudes from the second surface 213. Because the handle 330 is relatively large, it is convenient for the user to grip, thereby improving the user experience. Furthermore, the curvature change of the outer surface of the handle 330 is small, which can prevent hand scratches. Alternatively, the handle 330 can be omitted, and the user can directly drive the end of the second elastic segment 322 of the elastic drive member 320 away from the first elastic segment 321.

[0040] In another optional embodiment, the distance between the central axis of the limiting hole 211 and the two opposite sides of the clearance opening 212 is equal. The connecting assembly 300 includes a limiting rod 310, the two ends of which are rotatably connected to the two opposite side walls of the mounting groove 110. The limiting rod 310 has a first plane 312, a first arcuate surface 313, a second plane 314, and a second arcuate surface connected end to end in its circumferential direction. When the wearable device is in the first state, the first arcuate surface 313 and the second arcuate surface are opposite to each other in the thickness direction of the device body 100. The limiting rod 310 limits the inner wall of the limiting hole 211 through the first arcuate surface 313 and the second arcuate surface. In the first state, the limiting rod 310 is positioned opposite to the limiting hole 211 on both sides of its rotation axis in the thickness direction of the head 210. This helps to improve the force balance of the head 210, thereby further improving the connection stability between the connecting strap 200 and the device body 100. When the wearable device is in the second state, the first plane 312 and the second plane 314 are opposite to each other in the thickness direction of the device body 100, so that the limiting rod 310 is disengaged from the limiting hole 211. This allows the limiting rod 310 to pass through the clearance opening 212, so that the head 210 of the connecting strap 200 can be smoothly pulled out from the mounting groove 110. Of course, the limiting rod 310 can also be a cam-type structure.

[0041] In a further optional embodiment, the connecting assembly 300 further includes an elastic drive member 320 connected to the limiting rod 310. The elastic drive member 320 can drive the limiting rod 310 to rotate relative to the device body 100, so that the limiting rod 310 is engaged or disengaged from the limiting hole 211. The mounting groove 110 has a first sidewall 112 and a second sidewall 113 opposite to each other in the extension direction of the limiting rod 310. The limiting rod 310 includes a first connecting segment 315, a first limiting segment 316, a second connecting segment 317, a second limiting segment 318 and a third connecting segment 319 connected in sequence in its length direction. The elastic drive member 320 is connected to the second connecting segment 317. The first connecting segment 315 is rotatably connected to the first sidewall 112. The third connecting segment 319 is rotatably connected to the second sidewall 113. The first limiting segment 316 and the second limiting segment 318 are both provided with the aforementioned first plane 312, first arcuate surface 313, second plane 314 and second arcuate surface. In this design, the elastic drive element 320 is connected to the middle part of the limiting rod 310, which allows for a more balanced distribution of the driving force on the limiting rod 310, thereby improving the rotational and limiting stability of the limiting rod 310. Alternatively, the second connecting section 317 can be omitted; in this case, the first limiting section 316 and the second limiting section 318 are integrated, and the elastic drive element 320 can be connected to either the first connecting section 315 or the third connecting section 319.

[0042] Optionally, both the first connecting segment 315 and the third connecting segment 319 include a connecting sleeve, a connecting shaft, and an elastic element. The elastic element is disposed inside the connecting sleeve, with one end of the elastic element abutting against the bottom of the connecting sleeve and the other end of the elastic element connected to the first end of the connecting shaft, so that the connecting shaft can extend and retract relative to the connecting sleeve. The second end of the connecting shaft of the first connecting segment 315 is used for rotatably connecting with the first sidewall 112, and the second end of the connecting shaft of the third connecting segment 319 is used for rotatably connecting with the second sidewall 113.

[0043] In a further optional embodiment, both the first sidewall 112 and the second sidewall 113 are provided with a connecting hole 112a and a guide groove 112b. The guide groove 112b extends along the insertion direction of the head 210. The first connecting segment 315 is guided and engaged with the guide groove 112b of the first sidewall 112, so that the first connecting segment 315 is rotatably connected to the connecting hole 112a of the first sidewall 112. The third connecting segment 319 is guided and engaged with the guide groove 112b of the second sidewall 113, so that the third connecting segment 319 is rotatably connected to the connecting hole 112a of the second sidewall 113. In this scheme, during the installation of the connecting assembly 300, the guide groove 112b is used to provide guidance for the limiting rod 310, so that both ends of the limiting rod 310 are smoothly inserted into the connecting hole 112a, thereby improving the installation efficiency of the connecting assembly 300.

[0044] In another optional embodiment, the connecting strip 200 includes a strip body 220 and a mounting head 230. The strip body 220 has a first connecting portion 221 and a second connecting portion 222 disposed opposite to each other. The mounting head 230 is clamped between the first connecting portion 221 and the second connecting portion 222 to form a head 210. The mounting head 230 is provided with the aforementioned limiting structure. The mounting head 230 is provided with at least two positioning holes 231 in its thickness direction. The positioning holes 231 are spaced apart along the width direction of the connecting strip 200. At least one of the first connecting portion 221 and the second connecting portion 222 is provided with at least two positioning posts 221a. Each positioning post 221a is positioned and engaged with each positioning hole 231 in a one-to-one correspondence. In this design, the mounting head 230 is clamped between the first connecting part 221 and the second connecting part 222, i.e., it is bonded by an adhesive coating method. This helps to improve the connection stability between the mounting head 230 and the belt body 220. Furthermore, the mounting head 230 and at least one of the first connecting part 221 and the second connecting part 222 are positioned and engaged by the positioning post 221a and the positioning hole 231. This further helps to improve the connection stability and firmness between the mounting head 230 and the belt body 220.

[0045] Optionally, the main body 220 can be made of a plastic structure to improve the wearing comfort of the wearable device.

[0046] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
