Description

Technical Field

[0001] The utility model belongs to the technical field of laser optical path systems, and in particular relates to a mirror frame and an optical path system. Background Art

[0002] During the laser debugging process, in order to ensure that the direction of the optical path is consistent with the design, the requirements for the optical components of spatial light are relatively high. In particular, the reflector is the most common component in spatial light. The installation position of the reflector will directly affect the direction of the optical path. The reflecting surface must be perpendicular to the horizontal plane (in the pitch direction), and the angle between the reflecting surface and the incident laser must also be just right (in the horizontal direction). Otherwise, the optical path will be offset, the ideal direction will not be achieved, and the laser debugging cannot be completed.

[0003] Since the reflector needs to be fixed by a frame, in actual operation, the horizontal and pitch adjustments of the reflector are achieved by adjusting the frame. The horizontal adjustment is convenient, because the frame and the optical platform are locked by two screws, and there is a certain gap between the screws and the through-holes. By loosening the screws, the frame can be fine-tuned in the horizontal direction, and the screws can be tightened after reaching the ideal position. However, the commonly used frames can only achieve horizontal adjustment. Due to factors such as processing errors, the pitch direction often needs to be adjusted. The pitch direction can only be adjusted by placing a plug gauge at the bottom. When it needs to be tilted up, the plug gauge is placed on the front side, and when it needs to be tilted down, the plug gauge is placed on the back side. The pitch range is achieved by the thickness of different plug gauges.

[0004] While this method can address the pitch angle error issue to a certain extent, it is complex to adjust, requiring repeated loosening and locking of screws and inserting gauges of varying thicknesses to complete the adjustment. Furthermore, even after adjustment and fixation, if a gauge is inserted on one side but not on the other, the bottom of the frame will appear to be suspended. Over time, this tightening of the screws can cause stress deformation, leading to frame deformation and, in turn, optical path deviation. Utility Model Content

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] This application provides a mirror frame and optical path system, which are described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the description of each embodiment has its own focus. For details not described in one embodiment, please refer to the relevant descriptions of other embodiments.

[0039] See also Figures 1 to 4 In one embodiment, the frame includes: a base 1; a frame 2 for mounting an optical element 100; and a plurality of fixing members 3 for connecting the base 1 and the frame 2; wherein the base 1 is provided with a first curved surface 11, and the frame 2 is provided with a second curved surface 21 that cooperates with the first curved surface 11; when the base 1 and the frame 2 are connected, the first curved surface 11 and the second curved surface 21 abut and cooperate.

[0040] In this embodiment, when the base 1 and the frame 2 are connected by the fixing member 3, the first curved surface 11 of the base 1 abuts against the second curved surface 21 of the frame 2; since the first curved surface 11 and the second curved surface 21 are both curved, they can rotate relative to each other and can still maintain surface contact after rotation. Therefore, after adjusting the pitch angle of the optical element 100, the base 1 and the frame 2 can be firmly connected by the fixing member 3.

[0041] In some embodiments, the optical element 100 may be, but is not limited to, a reflector, a lens, or other optical element. The eyeglass frame of the present invention may be applicable to any scenario where it is necessary to conveniently adjust the angle of an optical element.

[0042] See also Figures 2 to 4Preferably, the first curved surface 11 is provided on the top surface of the base 1; the second curved surface 21 is provided on the bottom surface of the frame 2. This design facilitates processing and has a simple structure. Of course, in some other embodiments, the first curved surface 11 can also be provided at other locations on the base 1, and the second curved surface 21 can also be provided at other locations on the frame 2, as long as the base 1 and the frame 2 are connected by the abutment of the first curved surface 11 and the second curved surface 21, thereby facilitating adjustment of the pitch angle of the frame 2.

[0043] In this embodiment, the radii of the first arcuate surface 11 and the second arcuate surface 21 are equal, that is, the first arcuate surface 11 and the second arcuate surface 21 can effectively make surface contact after abutting each other, thereby ensuring a stable fit.

[0044] It should be noted that the axis where the centers of the first arcuate surface 11 and the second arcuate surface 21 are located may be perpendicular to the axis of the optical element 100 .

[0045] See also Figure 2 As an optional embodiment of the lens frame 2, the lens frame 2 includes: an optical element mounting portion 22 for mounting the optical element 100; a base plate 23 connected below the optical element mounting portion 22; and the second curved surface 21 is arranged on the bottom surface of the base plate 23.

[0046] In this embodiment, optionally, the optical element mounting portion 22 may have a cylindrical through hole, and the hole is used to accommodate the optical element 100; the optical element 100 may be fixed in the hole by some fixing mechanism.

[0047] See also Figure 2 and Figure 3 The bottom plate 23 is provided with first mounting holes 231 on both sides of the optical element mounting portion 22 for the fixing member 3 to pass through; the base 1 is provided with second mounting holes 12 corresponding to the first mounting holes 231 one by one.

[0048] In an optional embodiment, the fixing member 3 may be passed through the first mounting hole 231 and the second mounting hole 12 from top to bottom, and then the front end of the screw portion engages with the nut, thereby connecting the base 1 and the frame 2. In an optional embodiment, the second mounting hole 12 may be a threaded hole, and the fixing member 3 may be passed through the first mounting hole 231 from top to bottom, and the front end of the screw portion thereof engages with the second mounting hole 12, thereby connecting the base 1 and the frame 2. In an optional embodiment, see Figure 5, the fixing member 3 may also pass through the first mounting hole 231 and the second mounting hole 12 in sequence from top to bottom, and then the front end of the screw portion engages with the third fixing hole 201 on the fixing base 200, thereby connecting the base 1 and the frame 2 and fixing the base 1 to the fixing base 200. Of course, in an optional embodiment, the fixing member 3 may also pass through the first mounting hole 231, the second mounting hole 12 and the third fixing hole 201 on the fixing base 200 in sequence from top to bottom, and then the front end of the screw portion engages with the nut, thereby connecting the base 1 and the frame 2 and fixing the base 1 to the fixing base 200.

[0049] See also Figure 3 and Figure 4 Preferably, the upper surfaces of both ends of the bottom plate 23 are provided with third arc-shaped surfaces 232 ; the center of the third arc-shaped surface 232 is the same as that of the second arc-shaped surface 21 .

[0050] In some embodiments, the fixing member 3 is installed vertically. Therefore, ensuring that the center of the third curved surface 232 is the same as that of the second curved surface 21 can prevent the fixing member 3 from being poorly matched with the base plate 23 due to the tilt of the base plate 23 when the fixing member 3 is installed vertically.

[0051] Optionally, the first mounting hole 231 and the second mounting hole 12 are strip-shaped holes, and the length direction of the strip-shaped holes may be the same as the axis direction of the optical element 100 .

[0052] Based on the above embodiments, an embodiment of the present application further provides an optical path system, including the mirror frame described above.

[0053] Optionally, the optical path system may include a fixing seat 200 , and the mirror frame 300 is mounted on the fixing seat 200 via a fixing member 3 .

[0054] Specifically, the fixing seat 200 may be provided with a third fixing hole 201 for the fixing member 3 to enter. The fixing member 3 can connect the base 1 and the frame 2 and fix the base 1 on the fixing seat 200 .

[0055] In one application scenario, the contact surface between base 1 and frame 2 lies on arc R1. Frame 2 can be pitched on base 1 around the center point of this arc before securing fixture 3. Because R2 is concentric with R1, the contact surface between fixture 3 and frame 2 remains on R2 regardless of whether frame 2 tilts left or right. Therefore, when securing fixture 3 is tightened, the fixture 3 remains perpendicular to mounting base 200, even if the frame 2 tilts in pitch.

[0056] It should be noted that the various devices selected in this application (components whose specific structures are not specified) are all universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods.
