[0003] In existing assembled multi-light-path optical lenses, during the process of assembling each independent pedestal, each pedestal needs to be assembled, and the light path corresponding to each pedestal needs to be adjusted to meet the fixed angle requirements. This assembly and adjustment process is cumbersome and difficult to operate, resulting in low production efficiency.

[0033] The assembled multi-path optical lens in the prior art not only has the problem of cumbersome assembly and adjustment processes, but also, when the bases of the various optical paths are gathered on one side, to ensure that the lower lenses can be fully installed, the spacing between the lowest lenses is usually increased, resulting in a non-compact support structure for the entire lens. If the lenses are to be arranged under the predetermined relatively compact support structure, the outer diameter of the lowest lens can only be reduced, which results in a smaller lens aperture, affecting the optical performance of the lens. To solve the above problems, the specific embodiment of the solution is as follows:
[0034] See also Figure 1 、 Figure 2 This embodiment provides a one-piece lens that allows multiple optical systems to be arranged at predetermined angles. The one-piece lens primarily comprises an integrally molded lens mount 100 and multiple lens assemblies 200. The lens mount 100 is provided with multiple lens mounting cavities 120. Since the lens mount 100 is an integrally molded structure, the positions of the multiple lens mounting cavities 120 on the lens mount 100 are fixed after processing. The integrated lens mount 100 helps ensure the angles and stability of the optical systems of multiple channels, eliminating the need for assembly adjustments and significantly reducing assembly difficulty. The multiple lens mounting cavities 120 are arranged along a predetermined direction. For ease of structural description, the linear direction along which the multiple lens mounting cavities 120 are arranged is referred to as the X-direction, and the central axis of one of the multiple lens mounting cavities 120 is referred to as the Z-direction. For example, in this embodiment, the lens mount 100 has three lens mounting cavities 120. The central axis of the central lens mounting cavity 120 is referred to as the Z-direction, and the linear direction along which the three lens mounting cavities 120 are arranged is referred to as the X-direction. The central axes of the multiple lens mounting cavities 120 are arranged at predetermined angles. The ends of the multiple lens mounting cavities 120 that are closer to each other form a converging end 101, and the ends that are farther away form a diverging end 102. In the specific structure, the converging end 101 is used as the lower end and the diverging end 102 is used as the upper end. The central axes of the multiple lens mounting cavities 120 are closer to each other at the lower end and farther away from each other at the upper end. Multiple lens assemblies 200 are installed in the lens mounting cavities 120, one lens assembly 200 for each optical system, thereby arranging the multiple optical systems at predetermined angles. Each lens assembly 200 need only be installed and fixed in its corresponding lens mounting cavity 120 to ensure the specific predetermined angles for the multiple optical systems. The lens mount 100 can be made of an aluminum alloy, such as AL6061-T6. Using an aluminum alloy improves structural stability, and the structural strength ensures product quality.
[0035] The one-piece lens of this embodiment utilizes an integrally molded lens mount 100. This mount directly ensures that the central axes of the multiple lens mounting cavities 120 therein are arranged at predetermined angles. When the lens assemblies 200 are installed in the corresponding lens mounting cavities 120, an optical lens having multiple optical systems is formed. The integrally molded lens mount 100 thus ensures the predetermined angles between the various optical paths, eliminating the need to assemble and debug separate optical systems. This reduces the difficulty of lens operation and improves lens assembly efficiency.
[0036] See also Figure 2 、 Figure 3 Furthermore, the lens mounting cavity 120 includes a first mounting hole 121 closest to the converging end 101. The bottom surface of the first mounting hole 121 facing the converging end 101 forms a bearing surface 122. The mounting hole at the lowest end of the lens mounting cavity 120 is the first mounting hole 121. The lens assembly 200 includes a first lens 210 closest to the converging end 101. The end of the first lens 210 facing the converging end 101 rests on the bearing surface 122. The bearing surface 122 is the lowest support surface of the lens mounting cavity 120 and also serves as the mounting reference surface for the lens assembly 200. The bearing surface 122 in each lens mounting cavity 120 is set at a certain angle to the X-axis according to the requirements of the optical system. Therefore, the lens assembly 200 uses the angle of the bearing surface 122 as a reference, making it easy to determine the fixed matching angle of the optical axis of the optical system in each lens mounting cavity 120. Therefore, when the angles between the supporting surfaces 122 in each lens mounting cavity 120 are guaranteed, the supporting surface 122 is used as a reference end surface to facilitate the center deviation detection of the lens assembly in each lens mounting cavity 120, solving the problem of no reference when detecting this type of lens, thereby effectively ensuring the center deviation quality requirements of each optical path of the lens.
[0037] See also Figure 2 、 Figure 3Furthermore, one end of the first lens 210 facing the dispersing end 102 protrudes beyond the opening of the first mounting hole 121 facing the dispersing end 102. When the lens assembly 200 is installed in each lens mounting cavity 120, the outer diameter of the lens assembly 200 corresponds to the inner wall of the lens mounting cavity 120. The upper end surface of the first lens 210 located at the bottom is higher, so that the end surface of the lower first lens 210 is slightly higher than the edge of the opening of the first mounting hole 121. With this assembly scheme, when installing the first lens 210, the protruding side wall section can be used as a clamping point (force application point), facilitating clamping and adjustment of the first lens 210, thereby facilitating lens installation and adjustment. Furthermore, when fixing the first lens 210, the outer side of the protruding side wall section can be filled with glue. Due to the obstruction of the protruding side wall, the glue will not be applied to the end surface of the lens, thus ensuring the sealing of the gap between the first lens 210 and the first mounting hole 121.
[0038] See also Figure 2 、 Figure 3 、 Figure 4 Furthermore, a material-enhancing surface 123 is provided on the wall of the first mounting hole 121 in at least one lens mounting cavity 120. Typically, the first mounting hole 121 is circular, and the material-enhancing surface 123 fills a portion of the circular inner wall, forming a flat surface on the inner wall. If there are three or more lens mounting cavities 120, the material-enhancing surfaces 123 are typically arranged symmetrically about the central axis of the lens mounting cavity 120. If there are two lens mounting cavities 120, the material-enhancing surface 123 may be provided on a side proximal to the other lens mounting cavity 120.
[0039] In one solution, taking three adjacent lens mounting cavities 120 as an example, a first mounting hole 121 in the middle lens mounting cavity 120 is provided with a material-enhancing surface 123 on the wall. The material-enhancing surface 123 is located on both sides of the X-direction, and the distance between the material-enhancing surfaces 123 on both sides is less than the aperture of the arc surface of the first mounting hole 121. The corresponding first lens 210 is provided with cutting planes 211 symmetrically along the diameter. The first lens 210 is embedded in the first mounting hole 121 so that the cutting planes 211 match the material-enhancing surface 123. Please refer to Figure 2 、 Figure 4Furthermore, in the specific process, the first lens 210 is cut based on the original circular shape, forming cutting planes 211 on both sides of the radial direction. When such a first lens 210 is installed in the first mounting hole 121, the length of the lens in the X direction is reduced, while the lens in other directions still maintains the original diameter. In the side-by-side direction of the lens mounting cavity 120, the minimum square aperture space is reduced by the added surface 123, thereby achieving spatial avoidance, so that the first mounting holes 121 in different directions can be closer at the converging end 101, thereby achieving the angled setting of the three optical paths. If the added surface 123 is not provided, each first mounting hole 121 adopts a complete circular hole, which will cause interference at the converging end 101. To avoid this interference, one way is to increase the distance between each first mounting hole 121. This will result in the spacing between the three lens mounting cavities 120 being too large, which cannot meet the compact structural requirements of the lens. Secondly, the aperture of each first mounting hole 121 can be reduced. Each lens assembly 200 in the lens mounting cavity 120 has an area to be observed, but this results in a smaller light-passing aperture of each optical path, resulting in a smaller observation area. To address the above problem, a design is adopted in which a material-increasing surface 123 is provided on the hole wall of the first mounting hole 121, and a cutting plane 211 is formed on both radial sides of the first lens 210. This ensures that the light-passing aperture of the first lens 210 is not lost or lost to a minimum, thereby ensuring the maximum observation area. The cutting plane 211 is provided in the X-axis direction. The position of the cutting plane 211 reduces the overlapping aperture of the first mounting holes 121, ensuring that the observation aperture of adjacent first mounting holes 121 is maximized and that each lens mounting cavity 120 is more compact at the converging end 101 without interference.
[0040] See also Figure 2 、 Figure 3 、 Figure 4 In this embodiment, a material-enhancing surface 123 is provided in the first mounting hole 121 of each lens mounting cavity 120. Therefore, a material-enhancing surface 123 is provided on the first mounting hole 121 of each of the three lens mounting cavities 120, and a cutting plane 211 is also provided on the first lens 210 of each corresponding lens assembly 200. Because the material-enhancing surface 123 is provided in the X-axis direction, in the lens mounting cavity 120 inclined on both sides, the cutting plane 211 of the first lens 210 and the sidewall of the first mounting hole 121 with the material-enhancing surface 123 form a tight fit. When the first lens 210 is installed at an angle, the stability of the first lens 210 in the inclined lens mounting cavity can be ensured, thereby facilitating lens assembly. Moreover, the provision of the material-enhancing surface 123 can also make the first mounting holes 121 closer together at the converging end 101, thereby optimizing the lens structure.
[0041] For the first lens 210, a cutting plane 211 is only formed in the X direction, and the lens is not cut in other radial directions, thereby retaining all light apertures, and on the edge of the entire first lens 210, the lens edge height is still greater than the height of the first mounting hole 121, so that it is still convenient to clamp and adjust the first lens 210, and the sealing requirements at the gap between the first lens 210 and the first mounting hole 121 can be ensured.
[0042] See also Figure 2 、 Figure 3 Furthermore, the lens mounting cavity 120 of this embodiment further includes a plurality of lens mounting holes 124. These are located on the side of the first mounting hole 121 facing the dispersing end 102 and are sequentially interconnected. The apertures of the plurality of lens mounting holes 124 gradually increase in size as they move toward the dispersing end 102. The lens assembly 200 further includes a plurality of optical lenses 220, which are respectively mounted in the plurality of lens mounting holes 124. This allows the optical lenses 220 in the lens assembly 200 to be installed sequentially from bottom to top, facilitating assembly.
[0043] See also Figure 2 、 Figure 3 Furthermore, in this embodiment, a retaining ring 230 is disposed between the first lens 210 and each of the plurality of optical lenses 220. Because the edge thickness of each optical lens 220 is greater than the sidewall depth of the corresponding mounting hole 124, the optical lens 220 protrudes from the sidewall of the corresponding mounting hole 124. The retaining ring 230 can separate the optical lenses 220 in the lens assembly 200, preventing collisions, achieving optical path requirements, and facilitating assembly of the optical lenses 220. A locking ring 240 is disposed within the mounting hole 124 closest to the dispersion end 102, securing the optical lens 220 therein. The locking ring 240 can be threaded and positioned above the uppermost optical lens 220, thereby locking the lens assembly 200 within the lens mounting cavity 120.
[0044] See also Figure 1 、 Figure 4 Furthermore, the lens mount 100 in this embodiment includes multiple integrally formed pedestals 110. Each pedestal 110 is configured as a flat surface at both the converging end 101 and the diverging end 102, with a lens mounting cavity 120 extending through the flat surfaces at both ends. Specifically, the pedestals 110 are integrally formed at angles to each other, with the angles between the pedestals 110 being determined based on the angles of the optical paths of the lens assemblies mounted on the pedestals 110. Each pedestal is provided with a lens mounting cavity 120 corresponding to the lens assembly. The flat surfaces of each pedestal facilitate the processing of the lens mounting cavity 120 and ensure its quality.
[0045] Furthermore, a mounting hole (not shown in the figure) is provided on the side surface of the lens holder 100, through which the entire one-piece lens can be connected to an external device or tool.
[0046] In summary, the present application provides a one-piece lens that transforms the original assembly structure of each independent optical system into an integrated one-piece lens overall structure. By making improvements to the lens barrel and the lens, the one-piece one-piece lens structure provides stable and reliable structural support for the optical system composed of multiple channels, making it easier to assemble the lenses in each lens mounting cavity; using the angle between the supporting surfaces in each lens mounting cavity as a reference, it is easy to determine the fixed matching angle of the optical axis of each lens assembly. The design of providing a material-increasing surface on the wall of the first mounting hole and forming cutting planes on both radial sides of the first lens can minimize the support structure between the channels, which is conducive to achieving the maximum light aperture of each channel.
[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
