The subject matter herein generally relates to wearable devices, and more particularly to a wearable device having a connection structure.
Smart wearable devices, such as smart watches, bracelets, glasses, and necklaces, are becoming more and more popular. The existing smart necklaces in the related art include a lanyard detachably coupled to a necklace body. The lanyard is wrapped around a user's neck, and the necklace body may be used while walking or running. However, the main body of the smart necklace is prone to rotate relative to the lanyard when the main body is not held in place.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.

The wearable device 200 further includes a snap portion 210, a device main body 220, and a connecting member 230 configured to snap-fit with the connection structure 100. The snap portion 210 has a substantially T-shaped cross-section and protrudes from one side of the device main body 220. The device main body 220 is snap-fitted with the latching portion 23 of the connection structure 100 by the snap portion 210 on one end of the main body 10. The connecting member 230 is fixedly coupled to a second end of the main body 10 away from the device main body 220. In one embodiment, the connecting member 230 is a connecting cord which can be worn on the neck of a user.
In other embodiments, the snap portion 210 can be a recess, and the latching portion 23 of the fastening assembly 20 can be engaged in the snap portion 210.
The fastening assembly 20 is configured to rotate in the fastening groove 11, so that the first end portion 21 of the fastening assembly 20 rotates away from the snap portion 210 to disengage the latching portion 23 from the snap portion 210.
The main body 10 is substantially cylindrical. The fastening groove 11 has a substantially rectangular cross-section and extends from one end of the main body 10 to another end of the main body 10 along an axis of the main body 10. One end of the fastening groove 11 penetrates an end surface of the main body 10. A blocking portion 12 is located in the fastening groove 11. The blocking portion 12 is configured to limit movement of the latching portion 23 in the fastening groove 11.
In other embodiments, the fastening groove 11 may penetrate both ends of the main body 10 along the axis of the main body 10.
In other embodiments, the cross-sectional shape of the fastening groove 11 may be a triangle, a pentagon, a hexagon, or other shape, as long as the cross-sectional shape of the snap portion 210 is the same as the cross-sectional shape of the fastening groove 11 and can be fastened in the fastening groove 11.
The fastening assembly 20 is substantially elongated. The latching portion 23 can be snap-fitted with the snap portion 210 to fix the device main body 220 in the fastening groove 11. The fastening assembly 20 includes a rotating portion 24. The rotating portion 24 is substantially lug-shaped. The number of the rotating portions 24 is two, and the two rotating portions 24 are arranged in parallel and spaced apart. The two rotating portions 24 are rotationally coupled to the main body 10 through a rotary shaft 25 inside the fastening groove 11. The first end portion 21 and the second end portion 22 are respectively located on opposite sides of the rotating portion 24.
The fastening assembly 20 further includes a limiting portion 26. The limiting portion 26 is substantially cylindrical-shaped. The limiting portion 26 extends from the second end portion 22 and is configured to prevent the pressing member 30 from rotating.
In other embodiments, the limiting portion 26 can be a groove-shaped structure arranged on the second end portion 22, and one end of the pressing member 30 is locked in the groove structure to prevent the pressing member 30 from rotating.
The pressing member 30 is made of an elastic material. One end of the pressing member 30 abuts against the second end portion 22 of the fastening assembly 20, and a second end abuts against the main body 10 in the fastening groove 11. In one embodiment, the pressing member 30 is a spring and is sleeved on the limiting portion 26.

Compared with the related art, the first end portion 21 of the fastening assembly 20 can be rotated away from the snap portion 210 by pressing the second end portion 22 of the fastening assembly 20 to disengage the latching portion 23 from the snap portion 210. Thus, the latching portion 23 is easily disengaged from the snap portion 210, and a snap-fit coupling between the snap portion 210 and the latching portion 23 prevents the wearable device 200 from rotating during use.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
