Detailed Description

The embodiment of the invention provides a glasses structure which is used for realizing the adjustment of the space between glasses frames.

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Fig. 1 is a schematic structural diagram of an eyeglass structure according to an embodiment of the present invention, and fig. 2 is another schematic structural diagram of the eyeglass structure shown in fig. 1.

The glasses structure of the embodiment of the present invention is used for being worn by a user, and the glasses structure of the embodiment of the present invention may have various specific use scenarios, for example, the glasses structure of the embodiment of the present invention may be applied to Augmented Reality (AR) glasses.

As shown in fig. 3 and 4, the glasses structure according to the embodiment of the present invention includes a first frame 1, a second frame 2, a first rack 3, a second rack 4, a bridge 5, and a knob 6.

Wherein, first rack 3 and first picture frame 1 fixed connection, second rack 4 and second picture frame 2 fixed connection. For example, as shown in fig. 5, one end of the first rack 3 and the upper end of the first lens frame 1 are fixedly connected by a screw. One end of the second rack 4 is fixedly connected with the upper end of the second spectacle frame 2 through screws.

The first frame 1 and the second frame 2 according to the embodiment of the present invention may be used for mounting lenses.

The bridge 5 is located between the first frame 1 and the second frame 2. In other words, the first frame 1 and the second frame 2 are respectively located at both ends of the bridge 5.

In the embodiment of the present invention, the first rack 3 and the second rack 4 are slidably connected to the cross member 5, respectively. Since the bridge 5 is located between the first and second frames 1 and 2, the first and second racks 3 and 4 extend from opposite directions to be slidably coupled to the bridge 5.

The side of the knob 6 is provided with a gear, and the knob 6 is rotationally connected with the beam 5. In other words, the knob 6 can rotate relative to the cross beam 5. For example, the knob 6 and the beam 5 are rotatably connected through the shaft 10 and the shaft hole.

The knob 6 is located between the first rack 3 and the second rack 4, and the first rack 3 and the second rack 4 are respectively engaged with the gears of the knob 6.

Crossbeam 5 is located between first picture frame 1 and the second picture frame 2, first rack 3 and first picture frame 1 fixed connection, second rack 4 and second picture frame 2 fixed connection. Thus, the direction in which the first rack 3 extends from the first frame 1 to the knob 6 is opposite to the direction in which the second rack 4 extends from the second frame 2 to the knob 6.

When the knob 6 is rotated in one direction, the first rack 3 and the second rack 4 are moved toward each other, so that the interval between the first lens frame 1 and the second lens frame 2 is reduced. When the knob 6 is turned in the opposite direction, the first rack 3 and the second rack 4 are moved away from each other, so that the interval between the first lens frame 1 and the second lens frame 2 is increased. Like this, rotate knob 6, can drive first rack 3 and second rack 4 synchronous phase to each other removal or carry on the back of the body and move to the interval between adjustable first picture frame 1 and the second picture frame 2 has realized the regulation to the interval between the picture frame.

In order to limit the adjustment range of the distance between the first frame 1 and the second frame 2, optionally, as shown in fig. 6, a first limiting member 7 and a second limiting member 8 are provided on the bridge 5. One end of the second rack 4 far away from the second spectacle frame 2 is provided with a limiting block 9. The first limiting member 7 and the second limiting member 8 are arranged at intervals along the moving direction of the limiting member 9, and the limiting member 9 is located between the first limiting member 7 and the second limiting member 8.

For example, a cavity structure is disposed inside the cross beam 5, and the first limiting member 7 and the second limiting member 8 are disposed on an inner wall of the cavity structure. As shown in fig. 3, the cross member 5 includes a front cover 13 and a fixing plate 14, and the cavity structure is disposed between the front cover 13 and the fixing plate 14. And the first frame 1 and the second frame 2 are respectively used for connecting with the temples 15. The fixed plate 14 is disposed toward the temple 15. For example, as shown in fig. 2, the side of the first frame 1 is hinged to one temple 15, and the side of the second frame 2 is hinged to the other temple 15.

As shown in fig. 6, the first limiting member 7 and the second limiting member 8 are disposed on the side of the fixing plate 14 facing the cavity structure. A limiting block 9 is disposed at an end of the second rack 4 away from the second frame 2, the limiting block 9 is connected to a side surface of the second rack 4, for example, as shown in fig. 6, the first limiting member 7 and the second limiting member 8 are disposed between the first rack 3 and the second rack 4, and the limiting block 9 is disposed at a side of the second rack 4 close to the first rack 3.

Thus, the stopper 9 moves between the first stopper 7 and the second stopper 8, and the movement range of the second rack 4 is restricted by the abutment of the first stopper 7 and the second stopper 8 against the stopper 9. When the second rack 4 stops moving due to the abutment of the first stopper 7 and the second stopper 8 against the stopper 9, the knob 6 is restricted from rotating by the second rack 4, and the first rack 3 also stops moving. In this way, a limitation of the range of the spacing between the first and second spectacle frames 1, 2 is achieved.

Alternatively, as shown in fig. 2, 3 and 4, one end of the first rack 3 is fixedly connected to the first lens frame 1, and one end of the second rack 4 is fixedly connected to the second lens frame 2.

One end of the beam 5 extends into the first spectacle frame 1, and the beam 5 is connected with the first spectacle frame 1 in a sliding way. Particularly, the first frame 1 has a certain thickness, a cavity is arranged in the first frame 1, one end of the beam 5 extends into the cavity of the first frame 1, and the beam 5 and the first frame 1 can slide relatively.

The other end of the crossbeam 5 extends into the second spectacle frame 2, and the crossbeam 5 is connected with the second spectacle frame 2 in a sliding way. Particularly, the second frame 2 has a certain thickness, a cavity is arranged in the second frame 2, the other end of the beam 5 extends into the cavity of the second frame 2, and the beam 5 and the second frame 2 can slide relatively.

Therefore, the knob 6 is rotated, the knob 6 drives the first rack 3 and the second rack 4 to move towards or away from each other, the first frame 1 and the second frame 2 also move towards or away from each other, at this time, the beam 5 and the first frame 1 slide relatively, and the beam 5 and the second frame 2 slide relatively.

There are various specific ways to realize the sliding connection between the first rack 3 and the second rack 4 and the cross beam 5, for example, there are a first guide rail and a second guide rail on the cross beam 5, the first rack 3 can slide on the first guide rail, and the second rack 4 can slide on the second guide rail.

In a specific implementation manner, as shown in fig. 3 and 4, a cavity structure is provided inside the cross beam 5, the first rack 3 extends into the cavity structure from one end of the cross beam 5, and the second rack 4 extends into the cavity structure from the other end of the cross beam 5. Like this, first rack 3 and second rack 4 can slide in cavity structures, and cavity structures's wall and 3 sliding connection of first rack, cavity structures's wall also and 4 sliding connection of second rack to realized first rack 3 and second rack 4 respectively with crossbeam 5 sliding connection.

As shown in fig. 3 and 6, the knob 6 is located in the cavity structure, the beam 5 is provided with an opening 22, the knob 6 is provided with a rotating shaft 10, and the rotating shaft 10 is rotatably connected with the opening 22. In this way, a rotational connection of the knob 6 and the cross beam 5 is achieved, and the user can control the rotation of the shaft 10 through the opening 22, thereby rotating the knob 6. For example, a slot body is arranged on one side of the rotating shaft 10 close to the opening 22, and a user acts on the wall of the slot body to control the rotating shaft 10 to rotate, so that the knob 6 rotates along with the rotating shaft.

It should be understood that, in the embodiment of the present invention, the cavity structure in the cross beam 5 may be a rectangular parallelepiped structure, and openings are provided at two ends for the first rack 3 and the second rack 4 to extend into.

Optionally, as shown in fig. 7 and 8, the cross beam 5 further comprises an elastic member 11. The cross beam 5 is provided with a limiting groove 12, the groove wall of the limiting groove 12 surrounds the opening 22, and the groove wall of the limiting groove 12 is provided with a gear structure. For example, the limiting groove 12 is located on a wall surface of the cavity structure, and a gear structure is arranged on a groove wall surrounding the limiting groove 12, and the gear structure corresponds to the gear of the knob 6. The elastic element 11 may be fixedly connected to the wall of the cavity structure, or a part of the structure of the elastic element 11 may be embedded in the cross beam 5.

As shown in fig. 8, the elastic member 11 abuts against a side of the knob 6 away from the opening 22, so that the gear of the knob 6 is engaged with the gear structure of the limit groove 12.

The elastic piece 11 is abutted with one side of the knob 6 far away from the opening 22, so that the knob 6 moves towards the opening 22, the gear of the knob 6 is meshed with the gear structure of the limiting groove 12, namely, the gear of the knob 6 is clamped with the gear structure of the limiting groove 12, and the knob 6 is limited to rotate. Because the first rack 3 and the second rack 4 are respectively meshed with the gear of the knob 6. The knob 6 is restricted from rotating by the gear structure of the stopper groove 12, and the first rack 3 and the second rack 4 are also restricted from moving, so that the user cannot change the interval between the first rim 1 and the second rim 2 by stretching or contracting the first rim 1 and the second rim 2. This can secure the stability of the interval between the first lens frame 1 and the second lens frame 2.

Wherein, the maximum deformation length of the elastic element 11 is larger than the depth of the limit groove 12. The depth of the position-limiting groove 12 is the distance from the end of the opening 22 of the position-limiting groove 12 to the bottom surface of the position-limiting groove 12. When a user needs to adjust the distance between the first frame 1 and the second frame 2, the user can press the knob 6 at the opening 22 to move for a certain distance, for example, press the rotating shaft 10, so as to press the knob 6, such that the knob 6 compresses the elastic member 11, the knob 6 moves in a direction away from the opening 22, the gear of the knob 6 is separated from the gear structure of the limiting groove 12, and at this time, the first rack 3 and the second rack 4 are still engaged with the gear of the knob 6, respectively. Then, the user rotates knob 6, and the rotation of knob 6 drives first rack 3 and second rack 4 and moves in opposite directions or move back to the interval between adjustable first picture frame 1 and the second picture frame 2 has realized the regulation to the interval between the picture frame.

It should be understood that the elastic member 11 of the embodiment of the present invention has various specific implementations, for example, the elastic member 11 is a spring sheet, specifically, a wave spring sheet, a snap spring sheet, or an opposite spring sheet. In the example shown in fig. 8, the elastic member 11 is a wave-shaped elastic piece. For another example, the elastic member 11 is a compression spring, an elastic rubber, or a torsion spring, and the like, and the embodiment of the present invention is not limited in this respect.

The cross beam 5 can be realized in various ways, for example, as a single piece.

In a specific implementation, as shown in fig. 3, 4 and 6, the cross beam 5 includes a front cover 13 and a fixing plate 14, and the front cover 13 and the fixing plate 14 are fixedly connected. For example, the front cover 13 and the fixing plate 14 are fixedly connected by screws. Wherein the cavity structure is arranged between the front cover 13 and the fixing plate 14. Such a construction is easy to machine and assemble.

The first frame 1 and the second frame 2 are respectively connected to the temples 15. The fixed plate 14 is disposed toward the temple 15, and the opening 22 is disposed on the fixed plate 14. In this way, when the user wears the eyeglass structure according to the embodiment of the present invention, the opening 22 faces the user side.

As shown in fig. 2 and 9, the eyeglass structure optionally further comprises a nose pad 16, and the nose pad 16 is detachably connected to the cross member 5. The nose pads 16 are used to support the eyewear structure. The nose pad 16 is adapted to abut the bridge of the nose of the user. The nose pads 16 and the cross beam 5 are detachably connected, so that the nose pads 16 can be replaced conveniently. For example, the nose pad 16 can be easily replaced by the user after the nose pad 16 is damaged due to long-term use.

The nose pad 16 can be implemented in various ways, for example, as shown in fig. 9, the nose pad 16 includes a blade 17 and a seat 18, and the seat 18 includes a connecting member 19 and a shutter 20. Wherein, the connecting piece 19 is fixedly connected with the shielding piece 20, and the supporting blade piece 17 is fixedly connected with the connecting piece 19. The blade 17 is intended to abut the bridge of the nose of the user.

The connecting piece 19 is detachably connected with the cross beam 5 so as to realize the detachable connection of the nose pad 16 and the cross beam 5. The shield 20 covers the opening 22 so that excessive exposure to the environment at the opening 22 is avoided, thereby protecting the structure at the opening 22.

As shown in fig. 9, the connecting piece 19 and the shutter 20 are optionally "L" shaped. At this time, the opening 22 is located at the side of the cross member 5, and for example, as shown in fig. 3, the opening 22 is provided on the fixing plate 14. Since the connecting piece 19 and the shield 20 are L-shaped, the connecting piece 19 and the cross member 5 are connected, and the shield 20 abuts against the side surface of the cross member 5, so that the shield 20 covers the opening 22.

There are various ways of detachably connecting the connecting member 19 and the cross member 5, for example, a magnet 21 is provided on the connecting member 19, and the connecting member 19 is magnetically connected to the cross member 5 through the magnet 21.
