Detailed Description

The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, the smart glasses 10 of the present embodiment includes a frame 100, a temple 200, and a hinge assembly 300 rotatably connecting the temple 200 to the frame 100, so that the temple 200 can be opened and folded with respect to the frame 100, the number of the temples 200 is 2, and the number of the hinge assemblies 300 is 2, and the hinge assemblies correspond to the temples 200 one by one, in the present embodiment, the two hinge assemblies 300 have the same structure and are symmetrical to each other, so that only one hinge assembly 300 is described in the present embodiment, and in the present embodiment, the smart glasses 10 are in a worn state, the direction parallel to the line of sight of the user, the direction away from the face of the user is "front", and the direction close to the face of the user is "back".

Referring to fig. 2 and 3, the hinge assembly 300 of the present embodiment includes a front hinge 310 and a rear hinge 320, the front hinge 310 is located at a front side of the rear hinge 320, the front hinge 310 has a front end 311 and a rear end 312, the front end 311 is fixedly connected to the frame 100, the rear end 312 is rotatably connected to the rear hinge 320, and the rear hinge 320 is fixedly connected to the temple 200, so that the temple 200 is rotatably connected to the frame 100 through the hinge assembly 300. The front hinge 310 is formed with an elastic deformation part 313 capable of elastic deformation, the elastic deformation part 313 is positioned between the front end 311 and the rear end 312 and connects the front end 311 and the rear end 312, the thickness of the front end 311 and the rear end 312 is larger than the elastic deformation part 313, so as to improve the connection strength of the front hinge 310 and the spectacle frame 100 and the rear hinge 320.

The elastic deformation part 313 can be elastically deformed, so that the front hinge 310 has good elasticity and deformability, and then by using the smart glasses 10 of the hinge assembly 300 of the present embodiment, the reliability and comfort of the head clamping of the two temples 200 in the wearing state are greatly improved, and the elastic deformation of the elastic deformation part 313 can buffer the deformation of the temples 200, thereby effectively reducing the possibility of fatigue fracture caused by the stress deformation of the temples 200, and being beneficial to prolonging the service life of the smart glasses 10.

Further, as shown in fig. 2 and 3, the front hinge 310 extends in the front-rear direction and has an elongated shape, and similarly, the elastic deformation portion 313 also extends in the front-rear direction, and the elastic deformation portion 313 has a spiral shape twisted around the extending direction of the front hinge 310, that is, the elastic deformation portion 313 has a spiral shape twisted at a certain angle with the extending direction of the front hinge 310 as a reference axis. The elastic deformation part 313 of such a configuration may have a certain deformation capability in all of the left, right, up and down directions, so that it may cope with the uncontrollable directional deformation of the temple 200 occurring in daily use such as taking off or wearing glasses.

Since the temple 200 is likely to be deformed in the left-right direction during daily use such as taking or wearing glasses, the front hinge 310 is still elongated in the front-rear direction and the elastic deformation portion 313 is also elongated in the front-rear direction as another specific embodiment, however, the elastic deformation portion 313 is formed in an arc shape protruding to the left or right at this time. At this time, the elastic deformation portion 313 has a certain deformation capability in the left-right direction, and mainly copes with the deformation of the temple 200 in the left-right direction. Of course, if the front hinge 310 is elongated in the front-rear direction and the elastic deformation portion 313 also extends in the front-rear direction, the elastic deformation portion 313 may have a wavy shape extending in the front-rear direction so as to mainly cope with the deformation of the temple 200 in the left-right direction.

The elastic deformation portion 313 is a sheet metal member, that is, formed by sheet metal working. The elastic deformation part 313 may be made of high-elasticity stainless steel or titanium alloy, and has high strength and good elasticity, and the elastic deformation part 313 is made of sheet metal through twisting deformation.

As for the connection of the front hinge 310 to the frame 100, specifically, a connection portion 314 protruding forward is formed on the front end surface of the front end 311 of the front hinge 310, and the connection portion 314 is used to be embedded in the frame 100 and fixedly connected to the frame 100. Since the frame 100 is generally made of plastic, the front hinge 310 can be fixedly connected to the frame 100 by insert molding, and the connection portion 314 can be embedded in the frame 100 to greatly improve the bonding strength between the front hinge 310 and the frame 100.

Further, in the present embodiment, the connecting portion 314 is T-shaped, and the number thereof is 2, but may also be 1 or more than 2.

The rear hinge 320 is also made of metal, as shown in fig. 2, and is located on the outer side of the front hinge 310, one end of the rear hinge 320 is embedded into the temple 200 and fixed by dispensing, a protruding portion 321 is formed on the inner side of the rear hinge 320, the protruding portion 321 is rotatably connected with the rear end 312 of the front hinge 310, when the rear hinge 320 rotates to the maximum opening angle, the front end of the rear hinge 320 abuts against the outer side of the elastic deformation portion 313, the elastic deformation portion 313 can stop the temple 200 from driving the rear hinge 320 to further open to the outer side, and meanwhile, the elastic deformation of the elastic deformation portion 313 can also play a role in restraining and buffering the deformation of the temple 200 and the rear hinge 320.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
