Description

Technical Field

[0001] This utility model relates to the technical field of AR devices, and in particular to a disassembly structure for myopia lenses in AR devices. Background Technology

[0002] AR display devices enable real-world scenes and computer-generated virtual content to be simultaneously projected onto the retina via the human eye. Common AR display devices include head-mounted AR displays and AR glasses, with AR glasses being relatively lightweight and convenient to use. However, ordinary AR devices are typically designed for people with normal vision, while myopia already accounts for a significant proportion of the total population. Therefore, some existing AR glasses feature detachable lenses for easy replacement. However, existing lens removal structures for AR glasses generally suffer from inconvenience in disassembly and assembly. In view of this, this invention proposes a novel lens removal structure for AR devices to address these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a disassembly structure for myopia lenses in AR devices, which has the advantages of convenient and quick disassembly and assembly.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A detachable lens structure for an AR device includes a frame, a lens, and a locking ring.

[0006] The myopia lens is detachably installed in the lens hole of the frame; the locking ring is made of elastic material;

[0007] The lens hole sidewall is provided with a first locking groove; the peripheral wall of the myopia lens is provided with a second locking groove; when the myopia lens is installed in the lens hole, the locking ring is tightly fitted between the myopia lens and the lens hole, the outer side of the locking ring is engaged in the first locking groove and the inner side is engaged in the second locking groove;

[0008] The clamping ring is provided with a disassembly protrusion, and the lens hole edge of the frame is provided with a groove for the disassembly protrusion to be engaged.

[0009] Furthermore, the disassembly protrusion has a bevel on the outer side away from the lens hole, and a gap is formed between the bevel and the groove.

[0010] Furthermore, the frame has two lens holes, one on the left and one on the right, with two corresponding myopia lenses and two locking rings.

[0011] Furthermore, the myopia lens is detachably installed in the lens hole from the rear side; the detachment protrusion extends towards the rear side, and the groove is provided on the rear side of the frame; the front side of the frame is provided with an optical waveguide sheet.

[0012] Furthermore, the disassembly protrusion is located on the top of the clamping ring, and the groove is located on the top of the lens hole.

[0013] Furthermore, the disassembly protrusion is L-shaped.

[0014] Furthermore, the elastic material is rubber or silicone.

[0015] Furthermore, the upper left or upper right corner of the frame is provided with a mounting hole for mounting a camera.

[0016] With the above technical solution, when nearsighted individuals want to use the AR device, they can select a suitable prescription lens and then secure it by inserting it into the lens hole using a locking ring. Since the locking ring is made of elastic material, its inner and outer sides can be tightly fitted into the first and second locking slots respectively, achieving quick and secure installation of the lens and meeting the needs of nearsighted users. When non-nearsighted individuals want to use the AR device, they can pull out the disassembly protrusion from the slot, then pinch the disassembly protrusion to detach the locking ring and the lens from the lens hole, enabling convenient and quick disassembly.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] like Figures 1 to 4As shown, a myopia lens disassembly structure for an AR device includes a frame 1, a myopia lens 2, and a locking ring 3.

[0024] The myopia lens 2 is detachably installed in the lens hole 11 of the frame 1; the locking ring 3 is made of an elastic material. The elastic material can be rubber or silicone, etc.

[0025] The lens hole 11 of the frame 1 is provided with a first locking groove 111 on the side wall; the peripheral wall of the myopia lens 2 is provided with a second locking groove 21; when the myopia lens 2 is installed in the lens hole 11, the locking ring 3 is tightly fitted between the myopia lens 2 and the lens hole 11, the outer side of the locking ring 3 is engaged in the first locking groove 111 and the inner side is engaged in the second locking groove 21; the locking ring 3 is provided with a disassembly protrusion 31, and the edge of the lens hole 11 of the frame 1 is provided with a groove 112 for the disassembly protrusion 31 to be engaged.

[0026] Therefore, when nearsighted individuals want to use the AR device, they can select a suitable prescription lens 2 and then use the locking ring 3 to secure it into the lens hole 11. Since the locking ring 3 is made of elastic material, its inner and outer sides can be tightly fitted into the first locking groove 111 and the second locking groove 21, respectively, achieving quick and secure installation of the lens 2 and meeting the needs of nearsighted users. When non-nearsighted individuals want to use the AR device, they can pull out the disassembly protrusion 31 from the recess 112, then pinch the disassembly protrusion 31 to detach the locking ring 3 and the lens 2 from the lens hole 11, allowing for convenient and quick disassembly.

[0027] like Figure 4 In this embodiment, the outer side of the disassembly protrusion 31 away from the lens hole 11 is provided with a slope 311, and a gap 4 is formed between the slope 311 and the groove 112. The gap 4 is provided to facilitate the insertion of fingers or tools into the groove 112 to pull out the disassembly protrusion 31, further improving the convenience of disassembly and assembly efficiency.

[0028] In this embodiment, the frame 1 has two lens holes 11, one on the left and one on the right, with two corresponding myopic lenses 2 and two locking rings 3. The myopic lens 2 is detachably installed in the lens hole 11 from the rear side; the disassembly protrusion 31 extends towards the rear side, and the groove 112 is provided on the rear side of the frame 1; the disassembly protrusion 31 can be L-shaped and is provided on the top of the locking ring 3 to facilitate pulling the locking ring 3 and the myopic lens 2, while the groove 112 is correspondingly provided on the top of the lens hole 11.

[0029] The front side of the frame 1 is provided with an optical waveguide 5. This optical waveguide 5 is used to realize the AR function of the AR glasses and can reduce the size of the AR glasses, making them lightweight, compact, and easy to use. The upper left or upper right corner of the frame 1 may be provided with a mounting hole 12 for mounting a camera to facilitate real-scene shooting.
