Wearable device and strap adjusting and locking mechanism thereof

Abstract

The invention relates to a wearable device and a strap adjusting and locking mechanism thereof. The strap adjusting and locking mechanism comprises an adjusting buckle, an adjusting knob and two straps, and the adjusting buckle has an adjusting chute. At least one of the two straps is slidingly arranged in the adjusting chute, and the remaining strap is connected to the adjusting buckle in a matched way. The strap slidingly arranged in the adjusting chute is provided with a rack. The adjusting knob is rotatingly arranged to the adjusting buckle and includes a relatively rotatable button cap and a ratchet, one side of the ratchet away from the button cap is provided with a gear, the gear engages with the rack , and the two straps rotate in the same or opposite direction with the rotation ofthe gear. A limiting device for unidirectionally locking the ratchet is arranged between the ratchet and the adjusting buckle. The above strap adjusting and locking mechanism is mainly formed by three components, the structure is simple, the reduction of the failure rate is facilitated, the reliability is high, the repair is easy, the straps can be tightened or released by rotating the adjustingknob forward or reversely, the operation is convenient and quick, and the improvement of a user experience is helped.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a wearable equipment and its strap adjustment and locking mechanism. Background technique [0002] At present, wearable devices have been widely used in all walks of life. Taking VR devices as an example, VR devices are generally fixed on the user's head through head-mounted parts, which play an important role in the experience of the entire VR device. [0003] At present, some headsets with self-locking structures have complex structures, relatively low reliability, high failure rate, high cost, and difficult repairs; strap-on headsets have low cost, but poor product experience. With a sense of cheapness, it is easy to entangle hair when wearing it, and the process of adjusting the clamping force on the head is relatively low-end and cumbersome; the clamping force of the head clip-type headwear product on the wearer's headwear depends on the size of the wearer's hea...

[0003] At present, some headsets with self-locking structures have complex structures, relatively low reliability, high failure rate, high cost, and difficult repairs; strap-on headsets have low cost, but poor product experience. With a sense of cheapness, it is easy to entangle hair when wearing it, and the process of adjusting the clamping force on the head is relatively low-end and cumbersome; the clamping force of the head clip-type headwear product on the wearer's headwear depends on the size of the wearer's head circumference. When the force is too large, the chuck will be caused, and if it is too small, the product will not be fixed firmly.
