Furthermore, the embodiments and features described in these embodiments can be combined with each other unless otherwise specified.

[0035] In the description of the embodiments of this application, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. The terms "set", "open", "installed", "connected", and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, and integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0036] During use, optical lenses require fine-tuning of the frame angle, typically within ±5°, to meet the precision requirements of the mirror angle. Because the adjustment angle is small, it's currently common to manually tap one side of the frame for adjustment. However, if the tapping force is not controlled accurately, the adjustment angle can easily be too large. In this case, the frame needs to be tapped in the opposite direction, and the angle adjustment repeated until the desired result is achieved. Therefore, this method is time-consuming, labor-intensive, has poor accuracy, low efficiency, and requires skilled workers; inexperienced workers often struggle to achieve the ideal angle.

[0037] To improve the accuracy and efficiency of frame adjustment, see [link / reference]. Figures 1 to 5The present application provides a two-dimensional angle adjustment device, including a fixed frame 1, a movable frame 2 and a mirror frame 3; the mirror frame 3 is connected to the movable frame 2 via a horizontally arranged first rotating shaft 4, and the movable frame 2 is provided with a first driving mechanism 5 for driving the mirror frame 3 to rotate around the first rotating shaft 4; the movable frame 2 is connected to the fixed frame 1 via a vertically arranged second rotating shaft 6, and the fixed frame 1 is provided with a second driving mechanism 7 for driving the movable frame 2 to rotate around the second rotating shaft 6.

[0038] This application provides a two-dimensional angle adjustment device for adjusting the two-dimensional angles of a glasses frame 3, wherein the two-dimensional angles include azimuth and pitch angles. In use, a fixed frame 1 is fixed to other components, keeping the position of the fixed frame 1 unchanged. A first drive mechanism 5 drives the glasses frame 3 to rotate around a horizontally arranged first rotating shaft 4 to adjust the pitch angle of the glasses frame 3. A second drive mechanism 7 drives a movable frame 2 to rotate around a vertically arranged second rotating shaft 6. Since the glasses frame 3 is mounted on the movable frame 2, the movable frame 2 can drive the glasses frame 3 to rotate around the vertically arranged second rotating shaft 6 to adjust the azimuth angle of the glasses frame 3.

[0039] See Figure 1 This application also provides an optical device, including an optical mirror 10 and a two-dimensional angle adjustment device as described in the above embodiment. The optical mirror 10 is mounted on a frame 3. By mounting the optical mirror 10 on the frame 3, when the two-dimensional angle of the frame 3 is adjusted by the first driving mechanism 5 and the second driving mechanism 7, the two-dimensional angle of the optical mirror 10 is also adjusted simultaneously, so that the mirror surface of the optical mirror 10 meets the requirements of a precise mirror angle.

[0040] The two-dimensional angle adjustment device and optical equipment provided in this application embodiment improve the adjustment accuracy and efficiency of the frame angle compared with the prior art, while also reducing the requirements for worker experience.

[0041] Each of the first rotating shaft 4 and the second rotating shaft 6 may include one. See, for an example... Figure 1 , Figure 2 The system includes two first rotating shafts 4 and two second rotating shafts 6. The two first rotating shafts 4 are coaxially arranged, and the frame 3 is positioned between the two first rotating shafts 4. The left and right sides of the frame 3 are connected to the movable frame 2 via the first rotating shafts 4, allowing the frame 3 to rotate around the first rotating shafts 4. Similarly, the two second rotating shafts 6 are coaxially arranged, and the movable frame 2 is positioned between the two second rotating shafts 6. The upper and lower ends of the movable frame 2 are connected to the fixed frame 1 via the second rotating shafts 6, allowing the movable frame 2 to rotate around the second rotating shafts 6.

[0042] See Figure 3The first driving mechanism 5 includes a first lever 51, a first slider 52, and a first driving member; the first lever 51 is parallel to the first rotating shaft 4, the first slider 52 is connected to the frame 3, the first slider 52 is provided with a first sliding groove extending in the vertical direction, and the first lever 51 is slidably engaged in the first sliding groove; the first driving member is connected between the movable frame 2 and the first lever 51, and is used to drive the first lever 51 to move in the horizontal direction perpendicular to the first lever 51.

[0043] During operation, the first driving component drives the first lever 51 to move in a horizontal direction perpendicular to the first lever 51. The first lever 51 moves the first slider 52 in the same horizontal direction, while the first lever 51 slides within the first groove. This allows the first slider 52 to rotate the frame 3 around the first rotating shaft 4, thereby adjusting the pitch angle of the frame 3. The first driving mechanism 5 uses a toggle mechanism to adjust the pitch angle of the frame 3, and can adjust very small angles, further improving the adjustment accuracy of the pitch angle of the frame 3.

[0044] The first driving element can be a linear actuator, such as an electric actuator, that achieves linear motion. For example, see [link to example]. Figure 3 The first driving component includes a first screw 53 rotatably mounted on the movable frame 2 in a horizontal direction perpendicular to the first lever 51, a first nut 54 threadedly connected to the first screw 53, a first motor 55 mounted on the movable frame 2 and driving the first screw 53 to rotate, and the first nut 54 connected to the first lever 51.

[0045] Specifically, the two ends of the first screw 53 are connected to the movable frame 2 via bearing structures, allowing the first screw 53 to rotate around its own axis. The first motor 55 is mounted on the movable frame 2 and is connected to the first screw 53 via a transmission connection to drive the first screw 53 to rotate. The transmission method between the first motor 55 and the first screw 53 can be gear transmission, chain transmission, direct drive, etc. The first nut 54 is connected to the first lever 51 via a first connecting seat 56. The first connecting seat 56 can be a plate-like structure, a rod-like structure, or other irregularly shaped structure, etc., without specific limitations. During operation, the first motor 55 drives the first screw 53 to rotate, which in turn drives the first nut 54 to move on the first screw 53, and the first nut 54 then drives the first lever 51 to move. To improve the accuracy and stability of the movement of the first nut 54, the movable frame 2 is provided with a first guide structure to guide the movement of the first nut 54. For example, the first guide structure includes a first guide rail 57 mounted on the movable frame 2, the first guide rail 57 being parallel to the first screw 53, and the first nut 54 slidably engaging with the first guide rail 57. The first guide rail 57 guides the movement of the first nut 54, improving the accuracy and stability of the first nut 54's movement. In other embodiments, the first guide structure may also be a first guide groove provided on the movable frame 2, with the first nut 54 slidably engaging within the first guide groove.

[0046] See Figure 4 The second drive mechanism 7 includes a second lever 71, a second slider 72, and a second drive member. The second lever 71 is vertically arranged, and the second slider 72 is connected to the movable frame 2. The second slider 72 is provided with a second slide groove extending in the horizontal direction, and the second lever 71 is slidably engaged in the second slide groove. The second drive member is connected between the fixed frame 1 and the second lever 71 and is used to drive the second lever 71 to move in the horizontal direction perpendicular to the second slide groove.

[0047] During operation, the second driving component drives the second lever 71 to move in a horizontal direction perpendicular to the extension of the second slide groove. The second lever 71 moves the second slider 72 in this horizontal direction, while simultaneously sliding within the second slide groove. This causes the second slider 72 to rotate the movable frame 2 around the second rotating shaft 6, which in turn drives the eyeglass frame 3 to rotate around the second rotating shaft 6, thus adjusting the orientation angle of the eyeglass frame 3. The second driving mechanism 7 uses a tossing motion to adjust the orientation angle of the eyeglass frame 3, and can adjust a very small angle, further improving the adjustment accuracy of the orientation angle of the eyeglass frame 3.

[0048] The second driving component can be a linear actuator, such as an electric actuator, that achieves linear motion. For example, see [link to example]. Figure 4The second driving component includes a second screw 73 rotatably mounted on a fixed frame 1 along a horizontal direction perpendicular to the second slide groove, a second nut 74 threadedly connected to the second screw 73, a second motor 75 mounted on the fixed frame 1 and driving the second screw 73 to rotate, and the second nut 74 connected to the second lever 71.

[0049] Specifically, the two ends of the second screw 73 are connected to the fixed frame 1 via bearing structures, allowing the second screw 73 to rotate around its own axis. The second motor 75 is mounted on the fixed frame 1 and is connected to the second screw 73 via a transmission connection to drive the second screw 73 to rotate. The transmission method between the second motor 75 and the second screw 73 can be gear transmission, chain transmission, direct drive, etc. The second nut 74 is connected to the second lever 71 via a second connecting seat 76. The second connecting seat 76 can be a plate-like structure, a rod-like structure, or other irregularly shaped structure, etc., without specific limitations. During operation, the second motor 75 drives the second screw 73 to rotate, which in turn drives the second nut 74 to move on the second screw 73, and the second nut 74 then drives the second lever 71 to move. To improve the accuracy and stability of the movement of the second nut 74, the fixed frame 1 is provided with a second guide structure to guide the movement of the second nut 74. For example, the second guide structure includes a second guide rail 77 mounted on the fixed frame 1, the second guide rail 77 being parallel to the second screw 73, and the second nut 74 slidably engaging with the second guide rail 77. The second guide rail 77 guides the movement of the second nut 74, improving the accuracy and stability of the movement of the second nut 74. In other embodiments, the second guide structure may also be a second guide groove provided on the fixed frame 1, with the second nut 74 slidably engaging within the second guide groove.

[0050] See Figure 3 The fixed frame 1 includes a horizontally arranged fixed plate 11 and a fixed ring 12 disposed below the fixed plate 11; the second drive mechanism 7 is disposed above the fixed plate 11, the center line of the fixed ring 12 is horizontally arranged, and the movable frame 2 is connected to the fixed ring 12 via a second rotating shaft 6. To facilitate hoisting of the fixed frame 1, a lifting ring 13 is provided on the fixed ring 12. For protection of the second drive mechanism 7, see [reference needed]. Figure 1 , Figure 2 A second protective cover 14 is provided on the fixed plate 11, covering the second drive mechanism 7.

[0051] See Figure 3 The movable frame 2 includes a horizontally arranged movable plate 21 and a movable ring 22 disposed below the movable plate 21; a first drive mechanism 5 is disposed above the movable plate 21, the center line of the movable ring 22 is horizontally arranged, and the frame 3 is connected to the movable ring 22 via a first rotating shaft 4. The movable plate 21 is disposed below the fixed plate 11. For protection of the first drive mechanism 5, see [reference needed]. Figure 1 , Figure 2 The movable plate 21 is provided with a first protective cover 23 covering the first drive mechanism 5.

[0052] See Figure 2 , Figure 4 , Figure 5 A first locking mechanism 8 is provided between the frame 3 and the movable frame 2, and / or a second locking mechanism 9 is provided between the movable frame 2 and the fixed frame 1. By providing the first locking mechanism 8, the frame 3 and the movable frame 2 are locked together; by providing the second locking mechanism 9, the movable frame 2 and the fixed frame 1 are locked together. This prevents the adjusted two-dimensional angle of the frame 3 from changing during operation, further improving the reliability of the frame 3 during operation.

[0053] See Figure 5 The first locking mechanism 8 includes a first armature shaft 81, a first electromagnet 82, and a first connecting rod 83. The first armature shaft 81 is parallel to the first rotating shaft 4 and is rotatably mounted on the movable frame 2. The first electromagnet 82 is mounted on the movable frame 2 and one end of it is in contact with the outer peripheral surface of the first armature shaft 81. The two ends of the first connecting rod 83 are respectively hinged to the first armature shaft 81 and the frame 3.

[0054] During operation, when adjusting the pitch angle of the frame 3, the first drive mechanism 5 drives the frame 3 to rotate around the horizontally positioned first pivot 4. The frame 3, through the first connecting rod 83, drives the first armature shaft 81 to rotate around its own axis. During this process, the end of the first electromagnet 82 is always in contact with the outer circumferential surface of the first armature shaft 81. After the pitch angle of the frame 3 is adjusted, the first electromagnet 82 is energized and attracts the first armature shaft 81, preventing the first armature shaft 81 from rotating, thereby locking the frame 3 to the movable frame 2. Correspondingly, when the first electromagnet 82 is de-energized, the first electromagnet 82 loses its attraction to the first armature shaft 81, and the first armature shaft 81 can continue to rotate, releasing the locking state between the frame 3 and the movable frame 2.

[0055] See Figure 5 The second locking mechanism 9 includes a second armature block 91 and a second electromagnet 92. The second armature block 91 is mounted on the movable frame 2 and has a horizontally mounted second locking surface 93 on its top. The second electromagnet 92 is mounted on the fixed frame 1 and one end of it is in contact with the second locking surface 93.

[0056] During operation, when adjusting the orientation angle of the frame 3, the second drive mechanism 7 drives the movable frame 2 to rotate around the vertically arranged second rotating shaft 6. The movable frame 2 drives the second armature block 91 to rotate around the second rotating shaft 6. During this process, the end of the second electromagnet 92 is always in contact with the second locking surface 93 of the second armature block 91. After the orientation angle of the frame 3 is adjusted, the second electromagnet 92 is energized and attracts the second armature block 91, preventing the second armature block 91 from moving, thereby locking the movable frame 2 and the fixed frame 1. Correspondingly, when the second electromagnet 92 is de-energized, the second electromagnet 92 loses its attraction to the second armature block 91, the second armature block 91 can continue to move, and the locking state between the movable frame 2 and the fixed frame 1 is released.

[0057] In other embodiments, the first locking mechanism 8 and the second locking mechanism 9 can be telescopic locking mechanisms, push-pull locking mechanisms, clamping locking mechanisms, cam locking mechanisms, etc., or other existing locking structures, without specific limitations.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of this application and within the spirit and principles of this application shall still fall within the protection scope of the technical solution of this application.
