[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0040] Reference Figures 1 to 6 As shown, this embodiment provides an optical device adjustment frame, including a movable plate 1, a lens frame 2, a rotating body 3, an elastic element 4, and a locking element 5.

[0041] The movable plate 1 is provided with a support position 11 for supporting optical components.

[0042] The frame 2 is located on one side of the movable plate 1. At least one of the sides of the frame 2 and the movable plate 1 that are close to each other is provided with a conical groove 6, and the rotating body 3 is sandwiched between the frame 2 and the movable plate 1 and can rotate within the conical groove 6.

[0043] The elastic element 4 is connected to the movable plate 1 and the frame 2 respectively, so that the movable plate 1 can pitch and / or yaw relative to the frame 2 when the elastic element 4 extends or retracts, so as to adjust the attitude of the optical components. The locking element 5 is provided on the frame 2. The locking element 5 can be connected to the movable plate 1 when the optical components are adjusted to a preset attitude, so as to restrict the movement of the movable plate 1.

[0044] In specific implementation, refer to Figure 1 In the z-direction shown, the movable plate 1 is located above the lens frame 2, and the rotating body 3 is sandwiched between the movable plate 1 and the lens frame 2. An elastic element 4 is provided between the movable plate 1 and the lens frame 2. By providing a conical groove 6 on at least one of the lower surface of the movable plate 1 and the upper surface of the lens frame 2, the rotating body 3 is located in the conical groove 6 and can rotate within the conical groove 6. Thus, when the elastic element 4 extends or retracts, the movable plate 1 can pitch and / or yaw relative to the lens frame 2. That is, the movable plate 1 has at least two degrees of freedom, thereby achieving the purpose of adjusting the attitude of the optical components located on the movable plate 1, thereby realizing the adjustment of the optical path of the optical components.

[0045] It should be noted that the pitching of the moving plate 1 refers to the movement of the moving plate 1 around... Figure 1 The y-axis shown is the axis of rotation. The y-axis indicates that the moving plate 1 is rotating around the axis of rotation. The y-axis indicates that the moving plate 1 is swaying. Figure 1 The x-axis shown is the axis of rotation. When the elastic element 4 extends or retracts, the movable plate 1 can only wobble, or only pitch, or both wobble and pitch simultaneously, thereby achieving flexible adjustment of the attitude of the optical components.

[0046] In this embodiment, the lower surface of the movable plate 1 and the upper surface of the frame 2 can both be provided with conical grooves 6. That is, the conical groove 6 on the upper surface of the frame 2 can be the first conical groove 61, and the conical groove 6 on the lower surface of the movable plate 1 can be defined as the second conical groove 62. The rotating body 3 is located in both the first conical groove 61 and the second conical groove 62. At this time, the movable plate 1 and the frame 2 are tangent to the rotating body 3, making the rotation of the rotating body 3 smoother and more flexible, thereby allowing the movable plate 1 to smoothly pitch and / or yaw.

[0047] When the movable plate 1 moves to adjust the posture of the optical components to the preset posture, the locking piece 5 set on the frame 2 is connected to the movable plate 1 to restrict the movement of the movable plate 1. At this time, the optical components can be reliably fixed in the current preset posture for subsequent optical testing.

[0048] For example, the motion in this embodiment refers to achieving only pitch rotation, or only yaw rotation, or both pitch and yaw simultaneously.

[0049] For example, the elastic element 4 can be a spring or other component with elastic deformation properties.

[0050] For example, the rotating body 3 can be a steel ball or an iron ball, etc., to ensure that the rotating body 3 has sufficient structural strength.

[0051] The optical device adjustment bracket of this embodiment includes a movable plate 1, a lens frame 2, a rotating body 3, an elastic element 4, and a locking element 5. The lens frame 2 is disposed on one side of the movable plate 1. A conical groove 6 is provided on at least one of the sides of the lens frame 2 and the movable plate 1 that are close to each other. The rotating body 3 is sandwiched between the lens frame 2 and the movable plate 1 and can rotate within the conical groove 6, so that the elastic element 4 is connected to the movable plate 1 and the lens frame 2 respectively. Thus, by compressing or extending the elastic element 4, the movable plate 1 can be tilted and / or tilted relative to the lens frame 2 to adjust the attitude of the optical components, thereby achieving the purpose of adjusting the optical path of the optical components.

[0052] Meanwhile, a locking element 5 is provided on the frame 2. When the optical components are adjusted to the required preset posture, the locking element 5 is connected to the moving plate 1, thereby restricting the movement of the moving plate 1 and thus reliably and stably fixing the optical components carried on the moving plate 1 for subsequent use.

[0053] For example, in this embodiment, the locking member 5 can be detachably connected to the movable plate 1. When it is necessary to readjust the posture of the optical component, the locking member 5 can be detached from the movable plate 1, so that the movable plate 1 can move again under the extension and retraction of the elastic member 4, thereby realizing the adjustment of the posture of the optical component. This is suitable for scenarios where the posture of the optical component needs to be repeatedly adjusted, thereby improving practicality.

[0054] Furthermore, achieving high-stability fixation by increasing the stiffness of elastic elements, using a double-nut structure to fix the threaded pair supporting the moving plate, or setting a fixed threaded pair on the side can lead to metal debris or carbonization, thus affecting the stability and cleanliness of optical components. The optical adjustment bracket of this embodiment not only achieves highly stable adjustment and fixation of optical components but also avoids generating debris or other contaminants, making it suitable for applications requiring high stability and cleanliness of optical components.

[0055] Reference Figure 3 As shown, in some embodiments, the frame 2 is provided with a first receiving hole 21, and the movable plate 1 is provided with a second receiving hole 12 at a position corresponding to the first receiving hole 21. A portion of the elastic member 4 is located in the first receiving hole 21, and another portion of the elastic member 4 is located in the second receiving hole 12.

[0056] In this embodiment, by providing the first receiving hole 21 and the second receiving hole 12, the receiving operation of the elastic member 4 can be realized. Furthermore, by placing the elastic member 4 in the first receiving hole 21 and the second receiving hole 12, the problem of increasing the structural size of the entire optical device adjustment frame caused by placing the elastic member 4 on the outside of the lens frame 2 and the movable plate 1 can be avoided.

[0057] For example, in order to facilitate the placement of the elastic element 4 and to avoid interference with the movement of the elastic element 4, the first receiving hole 21 can be provided as a through receiving hole that penetrates the frame 2 along the direction from the frame 2 to the moving plate 1. Similarly, the second receiving hole 12 can be provided as a through receiving hole that penetrates the moving plate 1.

[0058] Reference Figure 1 As shown, in some embodiments, the frame 2 is provided with a first locking hole 22 communicating with the first receiving hole 21, and a first locking member connected to the elastic member 4 is provided in the first locking hole 22.

[0059] By providing a first locking hole 22 on the frame 2, the first locking member can be inserted into the first locking hole 22 and connected to the elastic member 4 to limit and fix the elastic member 4 and prevent the elastic member 4 from falling off.

[0060] Furthermore, refer to Figure 3 As shown, in order to facilitate the connection between the first locking member and the elastic member 4, a first ring 41 can be provided on the elastic member 4, and the first locking member passes through the first ring 41 to limit and fix the elastic member 4.

[0061] In addition, to ensure that the elastic element 4 has sufficient deformation length, the first ring 41 can be set at the end of the elastic element 4 away from the moving plate 1.

[0062] For example, the first locking hole 22 can be a cylindrical pin hole or a threaded hole, and the first locking member can be a locking pin that mates with the cylindrical pin hole or a screw that mates with the threaded hole. Specifically, the screw can be a full-thread screw or a partial-thread screw.

[0063] For example, when the elastic element 4 is set as a plurality of elements spaced apart along the circumference of the frame 2, the first locking hole 22 can be set as a plurality of elements. The plurality of first locking holes 22 are spaced apart along the circumference of the frame 2 so as to limit and fix the corresponding elastic element 4 through the first locking element in the different first locking holes 22.

[0064] Reference Figure 1 As shown, in some embodiments, the movable plate 1 is provided with a second locking hole 13 communicating with the second receiving hole 12, and a second locking member connected to the elastic member 4 is provided in the second locking hole 13.

[0065] By providing a second locking hole 13 on the moving plate 1, the second locking member can be inserted into the second locking hole 13 and connected to the elastic member 4 to limit and fix the elastic member 4 and prevent the elastic member 4 from falling off.

[0066] Furthermore, in order to facilitate the connection between the second locking member and the elastic member 4, a second ring 42 can be provided on the elastic member 4, and the second locking member passes through the second ring 42 to limit and fix the elastic member 4.

[0067] In addition, to ensure that the elastic element 4 has sufficient deformation length, the second ring can be set at the end of the elastic element 4 away from the frame 2.

[0068] For example, the second locking hole 13 can be a cylindrical pin hole or a threaded hole, and the second locking member can be a locking pin that mates with the cylindrical pin hole or a screw that mates with the threaded hole. Specifically, the screw can be a full-thread screw or a half-thread screw.

[0069] For example, when the elastic element 4 is set as a plurality of elements spaced apart along the circumference of the frame 2, the second locking hole 13 can be set as a plurality of elements. The plurality of second locking holes 13 are spaced apart along the circumference of the frame 2 so as to limit and fix the corresponding elastic element 4 through the second locking element in different second locking holes 13.

[0070] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the frame 2 has an adjusting member 7, and a locking member 5 is disposed on the adjusting member 7. The adjusting member 7 is threadedly engaged with the frame 2, and the adjusting member 7 can rotate under the action of external force to drive the elastic member 4 to extend and retract.

[0071] In other words, the outer wall of the adjusting member 7 is provided with a thread 77, and the frame 2 is provided with a threaded inner hole 24. The adjusting member 7 is threadedly engaged with the threaded inner hole 24, so that when the adjusting member 7 is rotated, the elastic member 4 can be driven to extend or contract.

[0072] For example, it can be set that when the adjusting member 7 is tightened, the elastic member 4 contracts, and when the adjusting member 7 is loosened, the elastic member 4 extends.

[0073] Furthermore, the rotation of the adjusting component 7 can be done manually or by using a drive component such as a motor.

[0074] In practice, in addition to using the rotating adjustment component 7 to drive the elastic component 4 to extend and retract, in other implementation methods, the elastic component 4 can also be directly driven to extend and retract through a drive mechanism.

[0075] For example, the initial minimum tensile force of the elastic element 4 can be initially evaluated by the following formula:

[0076] F=(m1+m2)×a×fs / n

[0077] Where F is the initial minimum tension of the elastic element 4, m1 is the mass of the optical component, m2 is the mass of the moving plate 1, a is the acceleration, fs is the safety factor, and n is the total number of elastic elements 4 in the adjustment frame.

[0078] Specifically, in order to achieve the maximum rotation angle of the moving plate 1, the stiffness coefficient of the elastic element 4 is minimized, which can achieve the minimum friction of the thread of the adjusting element 7, that is, the minimum wear of the thread.

[0079] Reference Figure 3 As shown, in some embodiments, a conical groove 14 is provided on the side of the movable plate 1 near the frame 2, and part of the adjusting member 7 is located in the conical groove 14 and rotates with the conical groove 14.

[0080] When it is necessary to adjust the attitude of the optical components mounted on the moving plate 1, the elastic element 4 extends or shortens. At this time, the moving plate 1 can rotate around the rotating body 3 around the x-axis and / or y-axis. At the same time, the part of the adjusting element 7 located in the conical groove 14 also rotates relative to the frame 2 around the x-axis and / or y-axis, thereby achieving the purpose of adjusting the attitude of the optical components located on the moving plate 1, and thus realizing the adjustment of the optical path of the optical components.

[0081] Reference Figure 3 As shown, in some embodiments, the adjusting member 7 includes an adjusting screw 71 and a spherical washer 72 connected to the adjusting screw 71. The adjusting screw 71 is threadedly engaged with the frame 2, and at least a portion of the spherical washer 72 is located within the conical groove 14 and is rotatably engaged with the conical groove 14.

[0082] Specifically, by adjusting the screw 71 and engaging the threaded inner hole 24 on the frame 2, the elastic element 4 can be stretched or shortened when the screw 71 is rotated. At this time, the moving plate 1 can rotate around the rotating body 3 around the x-axis and / or y-axis. Simultaneously, the spherical washer 72 is tangent to the conical groove 14 and also rotates relative to the frame 2 around the x-axis and / or y-axis, thereby achieving the purpose of adjusting the attitude of the optical components located on the moving plate 1, and thus adjusting the optical path of the optical components.

[0083] It should be noted that the pitch between the adjusting screw 71 and the threaded inner hole 24 determines the sensitivity of the optical device adjustment component, and the specific pitch can be set according to actual needs.

[0084] For example, the adjusting screw 71 and the spherical washer 72 can be integrally formed to save manufacturing steps and improve the structural strength of the entire adjusting component 7. In this case, the spherical washer 72 can be made of materials such as silicone or rubber to give it a certain deformation ability so that it can pass through the threaded inner hole 24 and extend into the conical groove 14.

[0085] Alternatively, the adjusting screw 71 and the spherical washer 72 can be positioned separately and then bonded together.

[0086] For example, the adjusting screw 71 can be coaxially arranged with the locking member 5.

[0087] Reference Figure 3 As shown, in some embodiments, the end of the frame 2 near the moving plate 1 is provided with a clearance hole 23 into which a partial spherical washer 72 can extend.

[0088] This design allows the spherical washer 72 to have some clearance when it moves within the conical groove 14, thus avoiding interference with the movement of the front end of the sphere.

[0089] Specifically, the clearance hole 23 is configured to communicate with the threaded inner hole 24 on the frame 2, and the inner diameter of the clearance hole 23 is larger than the inner diameter of the threaded inner hole 24, and the inner diameter of the clearance hole 23 is larger than the outer diameter of the spherical washer 72, so as to ensure that the spherical washer 72 can be smoothly inserted into the clearance hole 23.

[0090] Reference Figures 1 to 4 As shown, in some embodiments, the extension and retraction direction of the elastic element 4 intersects the line connecting the central axis of the adjusting element 7 and the central axis of the rotating body 3, so as to improve the adjustment stability of the optical device adjustment frame.

[0091] In specific implementation, the elastic element 4 can be set to at least two, and at least two adjusting elements 7 are provided. The at least two adjusting elements 7 are respectively provided on both sides of the rotating body 3 along the circumferential direction of the moving plate 1, and at least two elastic elements 4 are provided between the rotating body 3 and the adjusting elements 7.

[0092] In practice, the adjusting element 7 can be set on two adjacent sides of the moving plate 1, that is, on two sides that are perpendicular to each other.

[0093] In this embodiment, from a geometric perspective, a line segment is established connecting the center of the adjusting member 7 and the center of the rotating body 3. A plane is established through the midpoint of the line segment and perpendicular to it. The elastic members 4 are symmetrically arranged on both sides of the aforementioned plane. Where space permits, the elastic members 4 are positioned close to both the adjusting member 7 and the rotating body 3 to achieve optimal adjustment stability.

[0094] Reference Figure 1 and Figure 3As shown, in some embodiments, a portion of the adjusting member 7 is located outside the frame 2, and an operating hole 73 is provided on the outer wall of the portion of the adjusting member 7 located outside the frame 2 for external tools to be inserted.

[0095] In practice, when it is necessary to rotate the adjustment component 7, an external tool can be inserted into the operating hole 73, and the adjustment component 7 can be rotated by rotating the external tool, which saves manpower and is suitable for scenarios with ample operating space.

[0096] For example, an external tool could be a wrench.

[0097] For example, the operating holes 73 include a plurality of holes, which are spaced apart circumferentially along the adjusting member 7, so that a rotating operation can be achieved by inserting an external tool into different operating holes 73.

[0098] Reference Figure 6 As shown, in some embodiments, the outer wall of the portion of the adjustment member 7 located outside the frame 2 is provided with an anti-slip structure 74, so that the adjustment member 7 can be directly rotated by hand, making it suitable for scenarios with confined operating spaces.

[0099] For example, the anti-slip structure 74 can be an anti-slip texture, such as knurling. Alternatively, the anti-slip structure 74 can also be an anti-slip protrusion.

[0100] Reference Figure 3 As shown, in some embodiments, the frame 2 has an adjustment member 7. One of the adjustment member 7 and the movable plate 1 is provided with a first locking hole 75, and the other of the adjustment member 7 and the movable plate 1 is provided with a second locking hole 15 communicating with the first locking hole 75. The locking member 5 can be inserted into the first locking hole 75 and the second locking hole 15 when the optical components are adjusted to a preset posture.

[0101] In practice, the first locking hole 75 can be a smooth hole, the second locking hole 15 can be a threaded hole, and the locking component 5 can be a threaded fastener.

[0102] Specifically, for example, the light hole can be set on the adjusting member 7, and the threaded hole can be set on the adjusting member 7. After the threaded fastener passes through the light hole, it cooperates with the threaded hole to lock and fix the moving plate 1, so as to prevent the moving plate 1 from moving.

[0103] Reference Figure 3 As shown, in some embodiments, the side of the adjusting member 7 facing away from the moving plate 1 is provided with a first conical part 76, and the locking member 5 is fitted with a second conical part 51, which is rotatably engaged with the first conical part 76.

[0104] This arrangement allows for a certain pitch and / or yaw between the locking member 5 and the adjusting member 7, so as to adjust the position of the locking member 5 relative to the adjusting member 7, thereby facilitating the reliable locking and fixing of the moving plate 1.

[0105] For example, the first tapered portion 76 can be a tapered groove hole provided on the adjusting member 7, and the second tapered portion 51 can be a spherical washer provided on the locking member 5. Alternatively, the first tapered portion 76 can also be a spherical protrusion provided on the adjusting member 7, and the second tapered portion 51 can be a tapered washer provided on the locking member 5.

[0106] Reference Figure 3 As shown, in some embodiments, a washer 8 is provided on the side of the first tapered portion 76 away from the moving plate 1. The washer 8 is disposed between the first tapered portion 76 and the locking member 5 to avoid hard contact between the ends of the first tapered portion 76 and the locking member 5, which could cause damage.

[0107] Reference Figure 1 As shown, in some embodiments, the movable plate 1 is provided with a mounting groove 16, and the mounting groove 16 has a stepped portion 17. The side of the stepped portion 17 facing away from the lens frame 2 and the groove wall of the mounting groove 16 together form a bearing position 11 to facilitate the placement of optical components.

[0108] For example, the inner contour shape of the mounting groove 16 can be a rectangle or an ellipse, or a shape that matches the shape of the optical component.
