Description

Technical Field

[0001] This utility model relates to the field of optoelectronic equipment technology, specifically to a lens mounting structure and a camera positioning and aiming feedback device. Background Technology

[0002] With the rapid development of machine vision, intelligent monitoring, drone aerial photography, and industrial automation, cameras, as core imaging devices, face increasingly stringent requirements for performance and structural stability. In practical applications, camera lenses need to possess characteristics such as high-precision mounting, excellent heat dissipation, and resistance to vibration and interference to ensure image quality stability and long-term system reliability. Traditional lens mounting methods often employ threaded engagement or bayonet-type fixation. While these methods are simple in structure, they are prone to problems such as loosening, poor heat dissipation, or focus shift under frequent disassembly and assembly, high-temperature operation, or high-vibration environments.

[0003] However, existing lens mounting structures often have a single function and cannot meet multiple requirements. For example, most quick-release structures lack effective heat dissipation design, leading to heat accumulation during prolonged lens operation; while devices with heat dissipation functions mostly use fixed connections, which are cumbersome to install and remove and have low maintenance efficiency. At the same time, existing structures generally lack shock absorption and buffering mechanisms, making them susceptible to external vibrations in dynamic working environments, resulting in blurred images or positioning errors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lens mounting structure, including a camera; a mounting module, disposed at the front end of the camera, including a mounting ring disposed at the front end of the camera, and a mounting base disposed on one side of the mounting ring; a heat dissipation component, disposed at one end of the mounting ring, including a shock-absorbing ring disposed on the inner ring of the mounting base on the side away from the mounting ring.

[0006] As a further description of the above technical solution:

[0007] The mounting module includes snap-fit ​​components disposed inside both sides of the mounting ring.

[0008] As a further description of the above technical solution:

[0009] The snap-fit ​​assembly includes: an annular groove, formed on the inner wall of the mounting ring, and two sets thereof; a snap-fit ​​ring, located at the end of the mounting base away from the shock-absorbing ring, and inserted into the mounting ring; two sets of snap-fit ​​blocks, which slide on both sides of one end of the snap-fit ​​ring and within the annular groove; two sets of compression springs, located inside the snap-fit ​​ring near the snap-fit ​​block, with one end welded to the snap-fit ​​block; snap-fit ​​grooves, formed on both sides inside the mounting ring, located at one end of the annular groove, with the snap-fit ​​block snapped into the snap-fit ​​groove; and a pressing post, which slides horizontally on both sides outside the mounting ring, with one end abutting against the other end of the snap-fit ​​block.

[0010] As a further description of the above technical solution:

[0011] The annular groove is L-shaped and consists of a straight groove and an annular groove.

[0012] As a further description of the above technical solution:

[0013] The heat dissipation assembly includes: a lens disposed at the end of the mounting base away from the snap ring, with one end abutting against the inner wall of the shock-absorbing ring; a threaded ring disposed at one end of the lens and threadedly connected to one end of the mounting base; a heat-conducting ring disposed on the outer wall of the mounting base, with one end contacting the outer wall of the lens for heat transfer; and a heat sink disposed on the outer wall of the mounting base and bolted to the heat-conducting ring.

[0014] As a further description of the above technical solution:

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, this embodiment provides a lens mounting structure and camera positioning aiming feedback device, including: a camera 1; a mounting module 2, disposed at the front end of the camera 1, including a mounting ring 21, disposed at the front end of the camera 1, and a mounting base 22, disposed on one side of the mounting ring 21; a heat dissipation component 3, disposed at one end of the mounting ring 21, including a shock-absorbing ring 33 disposed on the inner ring of the mounting base 22 away from the mounting ring 21.

[0032] In this embodiment, the mounting module 2 and the heat dissipation component 3 constitute a lens mounting structure and camera positioning and aiming feedback device involved in this application.

[0033] Understandable Figure 1 The images only schematically illustrate some of the components included in the camera; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 The limitations mean that cameras can also include, compared to Figure 1 More or fewer parts.

[0034] It should also be understood that the camera 1, lens 31 and controller were all purchased from the market and are common knowledge in the field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Furthermore, in this embodiment, the mounting module 2 includes a mounting ring 21, a circular structure made of high-strength aluminum alloy, and a mounting base 22, also a circular structure made of high-strength aluminum alloy. The heat dissipation component 3 includes a shock-absorbing ring 33, a circular structure made of highly elastic rubber. The mounting module 2 achieves lens fixation and installation, while the heat dissipation component 3 achieves lens heat dissipation. This provides stable lens mounting and heat dissipation, ensuring lens stability and lifespan.

[0036] Example 2:

[0037] Based on Embodiment 1, in order to provide a stable fixing function, a mounting module 2 is set at the front end of the camera 1.

[0038] Specifically, the installation module 2 includes a snap-fit ​​assembly 23, which is disposed inside both sides of the installation ring 21.

[0039] In this embodiment, the mounting base 22 is fixed and disassembled via the snap-fit ​​assembly 23. This provides a stable fixing function, ensuring the stability and reliability of the mounting base 22.

[0040] Specifically, the buckle assembly 23 includes: an annular groove 231, formed on the inner wall of the mounting ring 21, and two sets thereof; a snap ring 232, located at the end of the mounting base 22 away from the shock-absorbing ring 33, and inserted into the mounting ring 21; two sets of snap blocks 233, which slide on both sides of one end of the snap ring 232 and within the annular groove 231; two sets of compression springs 234, located inside the snap ring 232 near the snap block 233, with one end welded to the snap block 233; a snap groove 235, formed on both sides inside the mounting ring 21, located at one end of the annular groove 231, with the snap block 233 snapped into the snap groove 235; and a pressing post 236, which slides horizontally on both sides outside the mounting ring 21, with one end abutting against the other end of the snap block 233.

[0041] In a preferred embodiment, the snap-fit ​​ring 232 is circular and made of high-strength aluminum alloy. The snap-fit ​​block 233 is rectangular and made of high-strength aluminum alloy. The compression spring 234 is made of high-strength spring steel. The pressing post 236 is cylindrical and made of high-strength aluminum alloy. When inserted into the mounting base 22, the snap-fit ​​block 233 slides along the annular groove 231, compressing the compression spring 234. After reaching the bottom, the mounting base 22 is rotated, and the snap-fit ​​block 233 slides into the snap-fit ​​groove 235. The compression spring 234 then returns to its original position, pushing the snap-fit ​​block 233 into the snap-fit ​​groove 235. For disassembly, pressing the pressing post 236 pushes the snap-fit ​​block 233 to slide, compressing the compression spring 234. Rotating the mounting base 22 in the opposite direction causes the snap-fit ​​block 233 to slide along the annular groove 231 and finally slide out. This provides stable fixing and disassembly functions, ensuring the stability and reliability of the mounting base 22.

[0042] Specifically, the annular groove 231 is L-shaped and is divided into a straight groove and an annular groove.

[0043] In this embodiment, the straight groove is used to insert the snap-fit ​​block 233, and the annular groove is used for the sliding and fixing of the snap-fit ​​block 233. This improves the sliding stability and reliability of the snap-fit ​​block 233.

[0044] Example 3:

[0045] Based on Embodiment 2, in order to provide effective heat dissipation, a heat dissipation component 3 is provided at one end of the mounting ring 21.

[0046] Specifically, the heat dissipation assembly 3 includes: a lens 31 disposed at one end of the mounting base 22 away from the snap ring 232, and one end abutting against the inner wall of the shock-absorbing ring 33; a threaded ring 32 disposed at one end of the lens 31 and threadedly connected to one end of the mounting base 22; a heat-conducting ring 34 disposed on the outer wall of the mounting base 22, and one end contacting the outer wall of the lens 31 for heat transfer; and a heat sink 35 disposed on the outer wall of the mounting base 22 and bolted to the heat-conducting ring 34.

[0047] This design features a cylindrical threaded ring 32 made of high-strength aluminum alloy. The heat-conducting ring 34 and the heat sink 35 are both made of high-thermal-conductivity aluminum alloy. Heat generated by the lens 31 is conducted to the heat sink 35 via the heat-conducting ring 34, and the heat sink 35 dissipates the heat into the air. This provides effective heat dissipation, ensuring the stability and lifespan of the lens 31.

[0048] In actual use, the user first inserts the end of the mounting base 22 with the snap ring 232 into the mounting ring 21, and inserts the snap blocks 233 on both sides into the straight groove of the annular slide 231. At the same time, the snap blocks 233 slide towards the middle of the snap ring 232 to compress the spring 234. When it reaches the bottom, the user rotates the mounting base 22 ninety degrees, so that the snap blocks 233 slide in the annular slide 231 until the snap blocks 233 slide into the snap groove 235. The compression spring 234 returns to its original position and pushes the snap blocks 233 to snap into the snap groove 235. Then the user screws the end of the lens 31 with the threaded ring 32 into the inside of one end of the mounting base 22. The outer wall of one end of the lens 31 is squeezed against the shock-absorbing ring 33. When the lens 31 generates heat, the inner ring of the heat-conducting ring 34 contacts the outer wall of the lens 31 to transfer heat to the heat sink 35, which dissipates the heat. When disassembling the lens 31 and the mounting base 22, the user rotates the lens 31 in the opposite direction, and the threaded ring 32 rotates in the opposite direction to be removed from one side of the mounting base 22. Then, the user presses the two sets of pressing posts 236. One end of the pressing post 236 pushes the locking block 233 to slide, squeezing the compression spring 234. The locking block 233 contacts the locking groove 235 and locks in place. Then, the user rotates the mounting base 22 ninety degrees in the opposite direction, and the locking block 233 slides along the annular groove 231. Finally, the user slides the mounting base 22 in the opposite direction, and the locking block 233 slides along the annular groove 231 to be removed.

[0049] After camera 1 is activated, lens 31 receives external scene light through the optical system, focuses it, and projects the light signal onto the photosensitive element of camera 1. If operating in low light or special spectral environments, the system automatically switches to the corresponding imaging mode to ensure image clarity. The internal processor of camera 1 performs noise reduction, enhancement, and distortion correction on the original image to improve image quality. A built-in algorithm identifies a preset target and marks its position coordinates in the image. Combining the camera's focal length, pixel size, installation angle, and position, the system converts the two-dimensional pixel coordinates in the image into three-dimensional spatial coordinates in the real world. The system calculates the optimal aiming point according to task requirements and determines whether the current posture is aligned with the target. Graphical information such as the aiming frame, distance indicator, and deviation indicator are overlaid on the display screen. The controller (not shown in the figure) receives signals and alerts the user through vibration via the control handle or the internal vibration motor of the device.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
