Abstract

The invention provides a tightness adjusting mechanism and wearable equipment with the same, the tightness adjusting mechanism comprises a shell, a first telescopic belt, a second telescopic belt and an adjusting assembly, the shell is internally provided with a slideway groove, the left side of the shell is provided with a first slideway hole, and the right side of the shell is provided with a second slideway hole; the first telescopic belt extends into the slide way groove, a first opening located in the slide way groove is formed in the first telescopic belt, and the first opening is provided with a first rack; the second telescopic belt extends into the slide way groove, a second opening located in the slide way groove is formed in the second telescopic belt, the second opening is provided with a second rack, and the first rack and the second rack are oppositely distributed up and down; the adjusting assembly is rotatably arranged on the shell and meshed with the first rack and the second rack, and by driving the adjusting assembly to rotate, the first telescopic belt retracts into the first sliding way hole and the second telescopic belt retracts into the second sliding way hole, or the first telescopic belt stretches out of the first sliding way hole and the second telescopic belt stretches out of the second sliding way hole.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a tightness adjustment mechanism. Background technique [0002] With the continuous development of the economy and the continuous advancement of science and technology, more and more wearable devices, such as head-mounted electronic devices, smart watches, smart bracelets, etc., have appeared in people's lives. Among them, head-mounted electronic devices are more and more widely used in people's lives, and head-mounted electronic devices are generally fixed to the head through a strap-type head-mounted structure. The head-mounted structure is mainly divided into ordinary strap type and mechanical type. Ordinary straps are generally composed of two side straps, and the two side straps are used to adjust the size of the headgear through Velcro or buckles, so that the headgear can fit well with the head. When the ordinary strap-type head-mounted structure is loosened, bot...

AI Technical Summary

Problems solved by technology

When the ordinary strap-type head-mounted structure is loosened, both hands are required to operate at the same time, which is troublesome to operate, and the two side straps are easy to loose after long-term use, which reduces the user experience

The mechanical head-mounted structure is generally adjusted by a rack and pinion, usually accompanied by the cooperation of the ratchet and the ratchet. There are also two problems. One is that there will be noise during adjustment, and the other is that you need to hold down the operation key while adjusting. It can be adjusted by turning the knob. In this case, two-handed operation is required. The operation is cumbersome and cannot meet the high requirements of users for user experience.
