[0021] Referring to the accompanying drawings, the stepless adjustable telescopic hinge for MR or VR glasses provided by this utility model includes a first connecting frame 1 and a second connecting frame 2. A telescopic adjustment structure is connected between the first connecting frame 1 and the second connecting frame 2. The telescopic adjustment structure includes an adjusting screw 3 and a nut 4. The adjusting screw 3 is rotatably connected to the first connecting frame 1, and the nut 4 is fixedly connected to the second connecting frame 2. Reference numeral 41 is the connecting pin between the nut and the second connecting frame 2. The adjusting screw 3 is connected to an adjusting knob 5. The telescopic hinge also includes a motor 6. The adjusting screw 3 is connected to a gear connecting mechanism. The motor 6 is connected to the gear connecting mechanism through a reduction mechanism, and can also drive the adjusting screw to rotate. The telescopic hinge also includes a guide mechanism for telescopic movement. The second connecting frame 2 is connected to the telescopic guide mechanism. The user can quickly adjust the distance between the first connecting frame 1 and the second connecting frame 2 (i.e., the distance between the first housing 100 and the second housing 200 below) to the desired focal length using the motor 6, and then fine-tune it by manually adjusting the adjusting knob 5. The gear connection mechanism includes a first gear 71 connected to the screw 3, a second gear 72 connected to the reduction mechanism, and a third gear 73 located between the first gear 71 and the second gear 72.
[0022] The MR or VR glasses are provided with a first housing 100 and a second housing 200, wherein the first housing 100 is located on the outer side (away from the eyes) and the second housing 200 is located on the inner side (closer to the eyes). The first housing 100 is connected to a first connecting frame 1, and the second housing 200 is connected to a second connecting frame 2. An opening 101 is provided on the first housing 100 to expose the adjustment knob 5, which can be manually adjusted by the user. The motor 6 is mounted on the first connecting frame 1, and the output shaft of the reduction mechanism passes through the second connecting frame 2 behind the first connecting frame and is connected to the second gear 72 of the gear connection mechanism.
[0023] The telescopic hinge houses the switch 61 of the motor 6. The switch 61 is mounted on the adjustment knob 5; the switch 61 is located outside the top of the adjustment knob 5 and also exposes the opening 101.
[0024] The adjusting knob 5 has an inwardly protruding inner end 51, which is connected to the first end of the adjusting screw 3. The outer end of the adjusting knob 5 has a mounting hole 52. The mounting structure includes a first part 621 located outside the top of the adjusting knob and a second part 622 located inside the adjusting knob. The first connecting frame 1 consists of front and rear parts. The second end of the adjusting screw 3 is rotatably connected to the rear part via a bearing 32. The first end of the adjusting screw 3 is located in the front part of the first connecting frame 1 and is rotatably connected to the front part via a bearing 31. Reference numeral 33 indicates the bearing seat of the bearing 31. The second connecting frame 2 is connected to the adjusting screw between the front and rear parts of the first connecting frame 1. The second connecting frame 2 has an external connecting part 20 that extends beyond the rear part and beyond its rear end.
[0025] The mounting hole 52 is provided with a bearing 53 and the second part 622. The bearing 53 is located between the adjustment knob 5 and the second part 622. The first part 621 has an opening inside the first housing 100 for routing wires 8. The wires 8 can be electrical connection wires or signal wires.
[0026] The guiding mechanism includes a pair of guide rods 9 located on the left and right sides of the screw 3. The guide rods 9 are fixed between the front and rear parts of the first connecting frame 1. The second connecting frame 2 is provided with holes and is slidably connected to the guide rods. The second connecting frame 2 may also be provided with a bearing 21, and the second end of the adjusting screw 3 passes through the bearing 21 and is connected to the first gear 71.
[0027] This invention increases the friction between the nut and the threaded bearing through design, thereby achieving an automatic locking effect. By designing the screw thread profile, the equivalent friction angle between components 3 and 4 can be determined. Selecting an appropriate lead and thread pitch diameter ensures that the thread helix angle is less than the equivalent friction angle. At this point, adjusting screw 3 and nut 4 achieve self-locking. If an external force pushes the first housing 100 and the second housing 200, the distance between the first housing 100 and the second housing 200 remains unchanged due to the self-locking function of adjusting screw 3 and nut 4.
