Description

Technical Field

[0001] This utility model relates to the field of AR glasses technology, and in particular to an AR glasses connection structure and AR glasses thereof. Background Technology

[0002] Smart glasses are intelligent wearable devices that combine computer technology, optical technology, and sensor technology. They can help users achieve augmented reality effects by overlaying digital images onto the lenses.

[0003] However, existing temples and frames are generally assembled by hinges. The existing structure does not adequately limit the opening angle of the temples and frames, making them prone to damage during use. Meanwhile, smart glasses have relatively high manufacturing costs, which affects the customer experience. At the same time, the hinge connection structure has too many components, resulting in low assembly efficiency and difficulty in controlling the yield rate, which is not conducive to mass production. Utility Model Content

[0004] In view of the above situation, it is necessary to provide an AR glasses connection structure and AR glasses to address the problems of insufficient limitation on the unfolding angle of the temples and frames and the excessive number of hinge connection components in the existing technology.

[0005] An AR glasses connection structure includes a first connector, an elastic member, and a second connector. One end of the first connector is connected to the temple, and the end of the first connector away from the temple is movably connected to the second connector. The two opposite sides of the elastic member are connected to the bottom of the first connector and the top of the second connector, respectively. The second connector is connected to the frame. The end of the first connector facing the second connector has a plurality of first protrusions, and the end of the second connector facing the first connector has a plurality of second protrusions. The positions of the first protrusions and the second protrusions correspond. The temple rotates relative to the second connector through the first connector to open or close the temple.

[0006] The beneficial effects of this utility model are:

[0007] The first and second connectors are connected by elastic elements, providing stable and smooth elastic damping during the temple unfolding process, enhancing the operating feel. The movable first and second connectors are connected by elastic elements, simplifying the assembly process, reducing mass production costs, and facilitating maintenance and replacement. The abutment design of the first and second protrusions can form a staged limit during rotation to restrict the angle of temple unfolding, thereby ensuring normal usage.

[0008] Furthermore, the first connector includes a first platform portion, and the first platform portion is provided with two first connecting holes at intervals at one end facing the second connector. The top of the outer wall of the first connecting hole is provided with the first protrusion, and the inner wall of the first connecting hole located on the inner side is provided with an internal thread. The first platform portion is recessed at one end facing the second connector to form a relief groove, and the relief groove is adjacent to the first connecting hole.

[0009] Furthermore, the second connector includes a second platform portion, with a plurality of fixing holes and a second connecting hole at opposite ends of the second platform portion, and two second protrusions on the top of the outer wall of the second connecting hole, with one end of the second protrusion facing away from the second connecting hole protruding from the side wall of the second connecting hole.

[0010] Furthermore, the first connecting hole and the second connecting hole are positioned correspondingly, and the rotating screw passes through the holes of the first connecting hole and the second connecting hole. One end of the rotating screw is provided with a nut, and the outer wall of the end of the rotating screw away from the nut is provided with an external thread, which is compatible with the internal thread.

[0011] Furthermore, the elastic element includes a first stepped surface, a bent surface, and a second stepped surface. The two opposite ends of the bent surface are connected to the first stepped surface and the second stepped surface, respectively. The second stepped surface extends away from the bent surface and abuts against the bottom of the first connecting element.

[0012] Furthermore, the first step surface is provided with a plurality of through holes, the positions of which correspond to the positions of the fixing holes.

[0013] This utility model also provides an AR glasses, including the AR glasses connection structure described above. Attached Figure Description

[0025] like Figures 1 to 5 As shown, an AR glasses connection structure includes a first connector 1, an elastic member 2, and a second connector 3.

[0026] Specifically, one end of the first connector 1 is connected to the temple, and the end of the first connector 1 away from the temple is rotatably connected to the second connector 2. The two opposite sides of the elastic member 2 are connected to the bottom of the first connector 1 and the top of the second connector 3, respectively. The second connector 3 is connected to the frame. The end of the first connector 1 facing the second connector 3 has two first protrusions 13, and the end of the second connector 3 facing the first connector 1 has two second protrusions 34. The positions of the first protrusions 13 and the second protrusions 34 correspond. The temple rotates relative to the second connector 3 via the first connector 1 to open or close the temple. The elastic member 2 connects the first connector 1 and the second connector 3, providing stable and smooth elastic damping during temple opening, enhancing the handling feel. The movable connection of the first connector 1 and the second connector 3 via the elastic member simplifies the assembly process, reduces mass production costs, and facilitates maintenance and replacement. The abutment design of the first protrusions 13 and the second protrusions 34 creates a staged limit during rotation to restrict the angle of temple opening.

[0027] Specifically, the first connector 1 includes a first platform portion 11. The first platform portion 11 is provided with two first connecting holes 12 at a distance from one end facing the second connector 3. The top of the outer wall of the first connecting hole 12 is provided with a first protrusion 13. The inner wall of the first connecting hole 12 located on the inner side is provided with an internal thread (not shown). The first platform portion 11 is recessed at one end facing the second connector 3 to form a relief groove 14. The relief groove 14 is adjacent to the first connecting hole 12.

[0028] Specifically, the second connector 3 includes a second platform portion 31. The second platform portion 31 has two fixing holes 32 and a second connecting hole 33 at opposite ends. The top of the outer wall of the second connecting hole 33 has two second protrusions 34. The end of each second protrusion 34 facing away from the second connecting hole 33 protrudes from the side wall of the second connecting hole 33. When the first connector 1 rotates clockwise relative to the second connector 2, that is, when the temple gradually changes from a closed state to an open state, the clearance groove 14 ensures that the first platform portion 11 and the second protrusions 34 do not interfere with each other. The first protrusion 13 gradually moves closer to the second protrusion 34, and finally, by the first protrusion 13 abutting against the portion of the second protrusion 34 that protrudes from the side wall of the second connecting hole 33, the first connector 1 stops rotating, forming a staged limiting position.

[0029] Specifically, the first connecting hole 12 and the second connecting hole 33 are positioned correspondingly. The rotating screw 4 passes through the holes of the first connecting hole 12 and the second connecting hole 33. One end of the rotating screw 4 is provided with a nut 41, and the outer wall of the end of the rotating screw 4 away from the nut 41 is provided with an external thread 42, which is compatible with the internal thread. The rotating screw 4 is passed through the holes of the first connecting hole 12 and the second connecting hole 33 one after the other. The external thread 42 and the internal thread are used to lock the rotating screw 4 to the first connecting hole 12 located on the inner side. At this time, rotating the temple will cause the first connecting piece 1, together with the relatively fixed rotating screw 4, to rotate around the second connecting hole 33 as the center.

[0030] Specifically, the elastic element 2 includes a first stepped surface 21, a bent surface 22, and a second stepped surface 23. The two opposite ends of the bent surface 22 are connected to the first stepped surface 21 and the second stepped surface 23, respectively. The second stepped surface 23 extends away from the bent surface 22 and abuts against the bottom of the first connecting element 1. The first stepped surface 21 is provided with two through holes 211, and the positions of the through holes 211 correspond to those of the fixing holes 32. The first step surface 21 is placed on the second platform part 31, and the elastic element 2 and the second connecting element 3 are fixed by screws passing through the through hole 211 and the fixing hole 32. The elastic element 2 can be made of shape memory alloy and has multiple characteristics such as shape memory, super elasticity and high damping. During the unfolding of the temple, the first connecting element 1 rotates relative to the second connecting element 3, and the second step surface 23 extends away from the bending surface 22 and abuts against the bottom of the first connecting element 1. It should be noted that the initial state of the second step surface 23 is not horizontal, but slightly raised, forming a 3° angle with the horizontal line. The abutment of the second step surface 23 against the bottom of the first connecting element 1 causes the second step surface 23 to deform slightly. The elastic element 2 can provide stable and smooth elastic damping for the first connecting element 1, enhancing the operating feel.

[0031] This invention connects the first connector 1 and the second connector 3 via an elastic element 2, providing stable and smooth elastic damping during the unfolding of the temples, enhancing the handling feel. The movable connection of the first connector 1 and the second connector 3 via the elastic element 2 simplifies the assembly process, reduces mass production costs, and facilitates maintenance and replacement. The abutting design of the first protrusion 13 and the second protrusion 34 can form a staged limit during rotation to restrict the angle of the temples unfolding, thereby ensuring normal usability.
