A hinge and wearable device

Abstract

The invention discloses a hinge, which comprises a fixed ratchet connected with a fixed part, a movable ratchet connected with a movable part and rotating synchronously with it, a first intermediate ratchet sleeved on a fixed shaft of the fixed ratchet and meshed with it, a sleeved The second middle ratchet engaged on the movable shaft of the movable ratchet, the first spring connected between the fixed ratchet and the first middle ratchet and tensioning the two, connected to the movable ratchet A second spring between the ratchet and the second middle ratchet and tensioning the two, the first middle ratchet and the second middle ratchet rotate synchronously and are connected to the connecting cable, and the fixed ratchet and the second middle ratchet are connected to each other The ratchets of the movable ratchet rotate in opposite directions. The invention can avoid the bending fatigue of the connecting cable under the condition of long-term reciprocating bending movement, and ensure the quality of signal transmission. The present invention also discloses a wearable device, the beneficial effect of which is as above.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a hinge. The invention also relates to a wearable device. Background technique [0002] With the development of virtual reality and augmented reality technologies, more and more head-mounted display devices, such as AR products and VR products, have been widely used. [0003] AR (Augmented Reality, Augmented Reality) technology is a technology that ingeniously integrates virtual information with the real world. It widely uses various technical means such as multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, and sensing. The generated text, images, 3D models and other virtual information are simulated and applied to the real world to achieve "enhancement" of the real world. [0004] VR (Virtual Reality, virtual reality) technology is a computer simulation technology that can create and experience a virtual world. It uses data in real ...

Problems solved by technology

[0006] However, although the connecting cables are generally designed to have a certain amount of excess length to prevent them from being pulled and broken when they are in a tight state for a long time, with the frequent reciprocating opening and closing movements of the temples, the connecting cables will always follow the temples. Rotation and reciprocating bending rotation, so that there is always a fixed bending point position (or bending area) on the connecting cable. During long-term use, the bending point is prone to bending fatigue and even breakage. Causes problems such as signal transmission distortion, increased signal loss, and signal interruption
