Eyewear having a frame, a hinge, and a hyperextendable temple having a flexible printed circuit (FPC) including service loops. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. A first service loop allows extension of the FPC when the temple rotates about the hinge, and a second service loop allows the temple to be radially extended away from the hinge.

A example hinge apparatus comprises a first hinge member and a second hinge member rotatably coupled together to form a rotation range between them. A hyperextension mechanism exerts a hyperextension clamping force when the members over-rotate outside the rotation range into a hyperextension zone. The hyperextension mechanism may comprise a cantilevered or clip structure providing the clamping force. A friction component can provide rotational resistance between the members during normal rotation, with less resistive torque than the hyperextension mechanism. Structural aspects include a part cylindrical shell structure dividing or enclosing compartments in the apparatus and allowing passage of an electrical FPC connection. Installation portions like pins, holes, and alignments mount the apparatus. The variable hyperextension clamping force protects sensitive augmented reality glasses components from damage during managed hyperextension, while also accommodating extended range of fit. Lightweight construction minimizes mass contribution. The hinge apparatus integrates smoothly into AR glasses, avoiding discomfort that could impair immersive experiences.

Embodiments may provide a first device that comprises eyeglasses, where the eyeglasses may further include a lens housing, a first temple and a second temple coupled to the lens housing, and a first and a second lens supported by the lens housing. The first device may further include a faade that covers the lens housing. The first device may further comprise an electronic component and at least one conductive path may be provided from the electronic component to the first lens having a portion that runs through the lens housing.

The present application provides a rotating mechanism of glasses, glasses and smart glasses. The rotating mechanism includes a first bracket, a second bracket, an elastic member, and a sliding member; the first bracket is provided with an accommodating space; the elastic member is provided in the accommodating space; the sliding member has one end movably connected to the first bracket by means of the elastic member, and another end rotatably connected to the second bracket; and when the second bracket rotates relative to the first bracket by means of the sliding member, the second bracket drives the sliding member to slide relative to the accommodating space, such that the elastic member is elastically deformed.

Glasses (200) comprising a front (210) and two temples (220) rotatably coupled to the front (210) so as to rotate between a first stable opening position and a second stable closing position, the front (210) comprises two first receiving seats (211), two hinge assemblies (100) each of which comprises a hinging body (110) coupled to a respective temple (210) so that it has an end portion (111) which protrudes overhanging with respect to the temple (220) and penetrates a respective one of such first receiving seats (211) in which it is rotatably coupled to the front (210), an elastic element (130) in abutment with a bottom wall of the respective first receiving seat (211) and the end portion (111), the elastic element (130) is preloaded in compression with a preloading force, the hinging body (110) and the elastic element (130) are configured in such a way that when the respective temple (220) is in the first stable opening position or in the second stable closing position, the elastic element (130) exerts a first thrust force that is equal and opposite to the preloading force on the end portion (111), and when the respective temple (220) passes from the first stable opening position to the second stable closing position, or vice versa, said elastic element (130) is compressed with a compressive force greater than said preloading force exerted by said end portion (111).

A temple connection structure includes a first bracket, a second bracket, a first elastic member and a limiting member. the first bracket and the second bracket are rotatably connected to each other, one of the first bracket and the second bracket is mounted at the temple and the other of the first bracket and the second bracket is mounted at the frame; the first elastic member is provided at the first bracket; the limiting member is provided at the second bracket and is provided with a limiting part; during a process of the temple flipping outward from an open position, the limiting part pushes against the first elastic member and causes the first elastic member to be in an elastic deformation state.
