The invention provides a pair of glasses.

In an embodiment of the present invention, as shown in fig. 1, the glasses include:

a mirror frame (not shown);

temples 100 rotatably coupled to the glasses frame; and

the opening degree adjusting mechanism 200 comprises a driving worm 210 movably arranged on the glasses frame and a driven worm gear 220 which is relatively arranged on the glasses frame in a rotatable mode, the driven worm gear 220 is fixedly connected with the glasses legs 100 and meshed with the driving worm 210, the opening degree adjusting mechanism 200 further comprises an adjusting portion, and the adjusting portion is used for driving the driving worm 210 to move so that the driven worm gear 220 rotates in the circumferential direction and the glasses legs 100 are driven to rotate relatively to the glasses frame.

Without losing generality, the mirror leg passes through hinged joint's mode realization and picture frame rotatable coupling, among the prior art, the aperture of glasses is decided on the size of picture frame, therefore the unable adjustment of glasses aperture, so that when same glasses were worn in different users, the circumstances of tension or tension can appear, tension can lead to user's head to receive the extrusion, tension can lead to glasses easily to drop, user's use experience can all be influenced to these two kinds of circumstances, in particular, the mirror leg is pressed from both sides in user's head for a long time tension, lead to the hinge fracture easily, destroy the stable connection between mirror leg and the picture frame.

In the present invention, the openness of the temples 100 can be flexibly adjusted by the openness adjusting mechanism 200, so that the openness of the glasses can be adapted to different users. The opening degree adjusting mechanism 200 is mainly used for conveniently and quickly adjusting the opening degree of the temples 100 by the cooperation of the driving worm 210 and the driven worm wheel 220. Wherein, the driving worm 210 is movably disposed on the frame, so that it can move relative to the frame; the driven worm gear 220 is fixedly connected to the temples 100, so that it can drive the temples 100 to move; further, the driving worm 210 is engaged with the driven worm wheel 220, and thus the driving worm 210 can drive the driven worm wheel 220 to rotate in the circumferential direction. Specifically, the user inputs a certain driving force into the adjusting part, and the driving force can be transmitted to the driving worm 210 to become a power for the driving worm 210 to move, so as to drive the driven worm gear 220 to rotate, so that the temple 100 and the driven worm gear 220 rotate together, and further, the angle between the temple 100 and the spectacle frame is changed, thereby achieving the purposes of adjusting the opening degree of the temple 100 and improving the adaptability of the spectacle.

Alternatively, the driving force input by the user at the adjusting portion may be an axial force, which indirectly drives the driving worm 210 to rotate circumferentially by directly moving the driving worm axially; alternatively, the user may rotate the adjusting portion to indirectly drive the driving worm 210 to move axially by directly rotating the driving worm 210 circumferentially. In addition, the rotation axis of the driven worm gear 220 should be overlapped with the rotation axis of the temple 100 to avoid interference between the rotatable connection between the temple 100 and the frame and the adjustment of the opening degree of the temple 100 by the driven worm gear 220, thereby ensuring that the opening degree adjusting mechanism 200 can effectively adjust the opening degree of the temple 100.

Further, as shown in fig. 1 and 2, in this embodiment, a limiting inclined groove 211 is provided on the driving worm 210, the opening degree adjusting mechanism 200 further includes a limiting member 230 fixed to the frame, and the limiting member 230 is slidably connected to the limiting inclined groove 211. In this embodiment, the limiting member 230 is engaged with the limiting inclined groove 211 to enable the driving worm 210 to perform circumferential rotation while performing axial movement, so as to stably drive the driven worm wheel 220 to perform circumferential rotation, thereby achieving the purpose of adjusting the opening degree of the temple 100. Of course, in other embodiments, a limiting groove may be formed on the mirror frame, one end of the driving worm 210 has a limiting flange slidably connected to the limiting groove, and the driving worm 210 may also perform axial movement and circumferential rotation synchronously through the matching of the limiting flange and the limiting groove.

Further, in the present embodiment, as shown in fig. 1 and fig. 2, the limiting inclined groove 211 is an annular inclined groove 212. It can be understood that, in the circular inclined groove 212, there are two points with the farthest axial distance, and the stopper 230 is slidably connected in the circular inclined groove 212 to limit the moving stroke of the driving worm 210. When the position-limiting member 230 reaches these two points, the driving worm 210 needs to reverse the direction of the movement. The advantage of such an arrangement is that, on one hand, the stopper 230 can be prevented from falling out of the limiting chute 211, so that the driving worm 210 can be stably connected to the mirror frame through the stopper 230; on the other hand, the driving worm 210 and the driven worm wheel 220 can be prevented from being separated from each other, so that the driving worm 210 and the driven worm wheel 220 can be stably meshed with each other, and the structural stability of the opening degree adjusting mechanism 200 is improved. Of course, in other embodiments, the limiting chute 211 may be a spiral groove with two closed ends, and the driving worm 210 may have the closest point and the farthest point.

Further, in the present embodiment, the position-limiting member 230 is an elastic member, and as shown in fig. 1 and fig. 2, the bottom wall of the position-limiting inclined groove 211 is provided with a plurality of position-limiting ribs 213 at intervals, so as to form different gear areas in the position-limiting inclined groove 211. It can be understood that, when the driving worm 210 moves axially by different distances, the position-limiting member 230 will move to different positions of the position-limiting inclined groove 211, the driven worm wheel 220 will rotate by different distances, and the temple 100 will obtain different opening degrees, which correspond to one another, so that the relative position of the position-limiting member 230 in the position-limiting inclined groove 211 can reflect the opening degree of the temple 100. In this embodiment, the limiting ribs 213 are used to separate different gear areas in the limiting chutes 211, and the opening of the temple 100 of the glasses is also different in the different gear areas.

It should be noted that, the bottom wall of the limiting chute 211 between two adjacent limiting ribs 213 forms a gear area, therefore, when the limiting member 230 switches different gear areas, the limiting member 230 needs to pass through the limiting ribs 213, at this time, the limiting member 230 is extruded by the limiting ribs 213, the friction between the limiting member 230 and the limiting chute 211 is increased to some extent, after the friction is fed back to the user through the adjusting part, the user can know that the limiting part 231 reaches another gear area through hand feeling, and the opening of the glasses also reaches another gear. So set up, the user can conveniently be as required with the aperture of glasses and transfer to different gears. In addition, after the user adjusts the opening degree of the temple 100 to a proper position, the external force is not enough to overcome the frictional force of the limiting member 230 at the limiting rib 213, and the temple 100 can be stably maintained at the corresponding shift position. Particularly, when the limiting chute 211 is an annular chute 212, when the glasses opening reaches the highest or lowest gear, the user can rotate the adjusting part continuously in the same direction, so that the glasses opening is excessive to the middle gear without changing the rotating direction.

Further, in this embodiment, the plurality of limiting ribs 213 are uniformly arranged on the bottom wall of the limiting inclined groove 211 to form a plurality of evenly distributed gear ranges, so that the gear ranges of the opening degree of the temple 100 can be more conveniently adjusted by the user. Thus, the user can more conveniently adjust the opening degree of the glasses legs 100 to the gear suitable for the user, the wearing comfort degree of the glasses is improved, and the adaptability of the glasses is improved.

Further, in this embodiment, as shown in fig. 2, the position-limiting member 230 includes a position-limiting portion 231, a spring 232 and a spring base 233, the spring base 233 is fixed with respect to the lens frame, and the position-limiting portion 231 is connected to the spring base 233 through the spring 232 and is slidably connected to the position-limiting inclined slot 211. When the limiting part 231 passes through the limiting convex rib 213, the compression amount of the spring 232 is increased, so that the elastic force applied to the driving worm 210 reaches the highest value, and the friction force between the limiting part 231 and the limiting inclined groove 211 reaches the maximum value, so that a user can feel obvious resistance on the adjusting part, and accordingly, the opening degree of the glasses leg 100 can be determined to be adjusted to a corresponding gear, the mechanism for adjusting the opening degree of the glasses leg by the opening degree adjusting mechanism is optimized, and the use experience of the user is improved. Of course, in other embodiments, the position-limiting member 230 may also be an integrally formed elastic material.

Further, in the present embodiment, as shown in fig. 1 and fig. 2, at least one end of the driving worm 210 is provided with an exposed convex pillar 214, and the convex pillar 214 is the adjusting portion. Thus, the adjusting portion and the driving worm 210 are integrally provided, and the acting force applied by the user on the adjusting portion can be directly transmitted to the driving worm 210, so that the driving worm 210 can be driven no matter the user acts on the adjusting portion by pressing or rotating. Particularly, when the user presses the adjusting portion, the two ends of the driving worm 210 should be provided with the exposed protruding columns 214, so that when the limiting member 230 reaches the two end points of the limiting inclined slot 211, the driving worm 210 can act on the closer protruding column 214, the driving worm 210 rotates the movement direction, the mechanism for adjusting the opening degree of the glasses legs by the opening degree adjusting mechanism is further optimized, and the use experience of the user is further improved. Of course, in other embodiments, the adjusting portion may be disposed separately from the driving worm 210, and fixedly connected to the driving worm 210 by means of a snap, a screw lock, or the like.

Further, in the present embodiment, the driven worm gear 220 is detachably coupled to the temple 100. In this way, when one of the temple 100 and the driven worm gear 220 is damaged, only the damaged part needs to be replaced accordingly, and the other does not need to be replaced, thereby improving the convenience of maintenance and saving the maintenance cost.

Further, in the present embodiment, as shown in fig. 1 and fig. 2, the driven worm gear 220 is connected with the temple 100 by screw locking, on one hand, the driven worm gear 220 can be fastened to the temple 100 to ensure that the movement of the temple 100 can be synchronized with the driven worm gear 220, thereby ensuring that the opening degree of the temple can be effectively adjusted by the opening degree adjusting mechanism; in another aspect, the driven worm gear 220 may be detachably connected to the temple 100, so as to improve the convenience of maintenance and save the maintenance cost. Of course, in other embodiments, the driven worm gear 220 and the temple 100 may be detachably connected by means of a snap, a rivet, or the like.

Further, in the present embodiment, the glasses are VR (Virtual Reality) glasses or AR (Augmented Reality) glasses. It can be understood that, in the prior art, the opening degree of the temple 100 of the VR glasses or the AR glasses is a fixed value, which cannot be customized individually, and even cannot match different opening degrees of the temple 100 for different users on the same device. And VR glasses or AR glasses in this embodiment are equipped with aperture adjustment mechanism 200, so, the user when using VR glasses or AR glasses, can adjust the 100 apertures of mirror leg according to self head circumference adaptability to guarantee the comfort level of wearing of self, thereby promote its user experience who uses this VR glasses or AR glasses. Of course, in other embodiments, the glasses may be smart glasses, bluetooth glasses, or the like.
