Leg-distance-adjustable glasses

Abstract

The invention discloses leg-distance-adjustable glasses. The glasses comprise a glasses shell, a left leg and a right leg, wherein the left leg and the right leg are connected to the glasses shell; aleft leg guide part is fixedly connected to the left leg, a right leg guide part is fixedly connected to the right leg, a left guide rail slidably connected with the left leg guide part is arranged atthe left end of the glasses shell, and a right guide rail slidably connected with the right leg guide part is arranged at the right end of the glasses shell; a leg position adjustment mechanism whichis a gear and rack mechanism is arranged between the glasses shell and the left and right leg guide parts. The relative position between the two legs is adjusted through the leg position adjustment mechanism so that the glasses can adapt to consumers of different head circumferences, and the use requirements of different consumers are met.

Description

technical field [0001] The invention relates to the technical field of spectacles, in particular to spectacles with adjustable temple distances. Background technique [0002] At present, the temples of AR glasses products are fixed, and only rely on the deformation of the temples to adapt to people with different head circumferences. Because the head circumferences of adults, children, and people in different regions vary greatly, the current products can only be adapted to a certain Class customer groups, limiting the market consumer groups. [0003] In order to realize the deformability of the temples, it is necessary to choose a specific material, generally nylon TR90, which is relatively expensive, and the price is about 7 times that of ordinary plastic materials. Moreover, the range of material options is small, and materials cannot be replaced when there is a problem with the supply chain or product quality. In addition, because the temples need to be deformed when w...

AI Technical Summary

Problems solved by technology

Moreover, the range of material options is small, and the material cannot be replaced when there is a problem with the supply chain or product quality

In addition, since the temples need to be deformed when worn, the internal space of the bending area cannot place related devices, and related devices need to be placed in other parts, which increases the product volume

Device wiring needs to pass through the bending area, which increases the difficulty and cost of wire design
