Description

Technical Field

[0001] This invention relates to the field of optical lens technology, and more specifically, to an optical lens. Background Technology

[0002] Optical lenses are important optical devices that use the principles of light refraction and reflection to clearly image external objects onto a photosensitive element. They are widely used in fields such as photography, security monitoring, medical testing, and aerospace. As various industries continue to increase their requirements for optical imaging quality and equipment portability, optical lenses face many challenges in terms of ease of installation, protective performance, adaptability, and ease of maintenance.

[0003] A search revealed a Chinese patent application with patent number CN201720805793.3, which discloses a lens mount assembly structure, including a base for placing a photosensitive film, a mount adapter ring for adjusting the focal length of an optical lens detachably connected to the base, and the optical lens being rotatably connected to the mount adapter ring.

[0004] Although the aforementioned patent achieves optimal imaging by adjusting the back focus of the lens through an optical lens and a bayonet adapter ring, and then fixing it to the base via the bayonet adapter ring, thus enabling reliable and convenient lens replacement for the imaging system and adapting to different shooting scenarios to achieve high-resolution and high-quality imaging, the following shortcomings still exist during use: 1. The optical lens connection method is cumbersome to operate, and the connection structure lacks stability. In vibrating environments, there is a risk of the lens and adapter ring falling off, which may cause equipment damage and data loss; 2. The lack of an effective buffering mechanism can easily lead to damage to the precision components inside the lens.

[0012] As a preferred technical solution of this application, the temperature drift adaptive calibration component includes a T-shaped block symmetrically slidably connected to the outer wall of the adapter ring. A docking ring is fixedly connected to the outer wall of the T-shaped block, and the docking ring is threadedly connected to the optical lens body. A symmetrically distributed shape memory alloy bracket is fixedly connected to the outer wall of the docking ring. A heat-conducting rod is fixedly connected to the end of the shape memory alloy bracket away from the docking ring. A heat insulation cover is fixedly connected to the outer wall of the heat-conducting rod. A heating ring is fixedly connected to the inner wall of the heat insulation cover, and the heating ring is fixedly connected to the heat-conducting rod. A uniformly distributed extrusion rod is fixedly connected to the outer wall of the heat insulation cover, and the end of the extrusion rod away from the heat insulation cover abuts against the outer wall of the pressure ring. A control chip is fixedly connected to the outer wall of the heat insulation cover, and the outer wall of the control chip is electrically connected to the heating ring.

[0013] As a preferred technical solution of this application, the positioning component includes a strong spring B that is uniformly and fixedly connected to the outer walls of the fixed cover and the transmission cover. A positioning ball is fixedly connected to the outer wall of the strong spring B, and the positioning ball is located on the inner wall of the positioning hole.

[0014] As a preferred technical solution of this application, the locking anti-fall-off component includes a slider slidably connected to the inner wall of the slide groove, a locking ring fixedly connected to the outer wall of the slider, uniformly distributed pressing blocks fixedly connected to the outer wall of the locking ring, and uniformly distributed conical push blocks fixedly connected to the outer wall of the locking ring.

[0015] As a preferred technical solution of this application, a strong spring A is fixedly connected to the outer wall of the slider, and the end of the strong spring A away from the slider is fixedly connected to the slide groove.

[0016] As a preferred technical solution of this application, a triangular groove is provided between the lens mount and the card plate, and the triangular groove provides movable space for the card plate.

[0017] As a preferred technical solution of this application, a pressure ring is fixedly connected to the inner wall of the lens mount, and a photosensitive film is fixedly connected to the outer wall of the pressure ring, and the photosensitive film is used in conjunction with the optical lens body.

[0018] As a preferred technical solution of this application, the outer wall of the extended protective cover is threaded with a light shield, which is used to reduce stray light entering the lens.

[0019] As a preferred technical solution of this application, both the transmission cover and the outer wall of the fixed cover are fixedly connected with uniformly distributed guide blocks, and the guide blocks are slidably connected with the guide grooves.

[0020] As a preferred technical solution of this application, a protrusion is fixedly connected to the outer wall of the card plate, and the outer wall of the protrusion abuts against the outer wall of the extrusion block.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In the scheme of this application:

[0023] 1. By setting up a quick-connect design for the card plate and card block, the installation time of the lens mount and adapter ring is shortened, and the lens installation can be completed quickly without delaying the shooting opportunity. At the same time, the compression block in the locking anti-drop component can prevent the card plate from moving outward, thereby preventing the card block from detaching from the card plate and locking the adapter. Through the dual action of the card plate limiting and the locking ring locking, the card block is limited and reinforced from two directions, effectively preventing the lens from falling off accidentally, ensuring the safety and stability of the shooting equipment, and avoiding equipment damage and loss of shooting content due to lens falling off. It solves the problems of the existing optical lens connection method being cumbersome to operate and having poor connection structure stability, and the risk of lens and adapter ring falling off in the vibrating environment, which may cause equipment damage and data loss.

[0024] 2. The retractable protective assembly adopts a multi-level structural design. When the lens is subjected to external impact, each protective layer can effectively absorb and defend against the impact force, avoiding direct damage to the lens and protecting the delicate optical components and mechanical structure inside the lens to the greatest extent. At the same time, the retractable protective assembly uses a threaded connection between the fixed cover and the adapter ring, which makes the disassembly and replacement process simple and convenient, reducing the difficulty and cost of later maintenance. It solves the problem that the lack of an effective buffer mechanism in the existing technology can easily lead to damage to the delicate components inside the lens.

[0025] 3. The temperature drift adaptive calibration component can compensate for lens focal length drift caused by temperature changes in real time, automatically maintaining the imaging sharpness of the optical system without manual intervention. Especially in environments with alternating high and low temperatures or extreme temperatures, it can still ensure the stability of the lens, significantly improving the environmental adaptability and imaging reliability of the optical lens and expanding the application scenarios of the device. In addition, the component has a compact structure, is integrated inside the lens, does not add extra volume, and has a fast response speed and low power consumption, taking into account both practicality and energy efficiency.

[0026] 3. Through the multi-level telescopic structure of the telescopic protective component, combined with the flexible positioning of the positioning ball and positioning hole in the positioning component, the optical lens can adapt to lenses of different lengths, improving the versatility and applicability of the product, reducing equipment procurement costs, and making the equipment easier to carry and manage.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0039] like Figures 1-9 As shown, this embodiment proposes an optical lens, including a camera 1, a lens mount 2 attached to the outer wall of the camera 1, and uniformly distributed clamping plates 10 fixedly connected to the outer wall of the lens mount 2. The clamping plates 10 are clamped to an adapter ring 4 via clamping blocks 9. The adapter ring 4 enables the camera 1 to adapt to different optical lens bodies 6. The adapter ring 4 is connected to the optical lens body 6 via a temperature drift adaptive calibration component. The optical lens body 6 is a fixed-focus lens. Optimal imaging is achieved through threaded adjustment between the adapter ring 4 and the optical lens body 6. The outer wall of the lens mount 2 has uniformly distributed sliding grooves 13. The lens mount 2 also includes:

[0040] The retractable protective assembly includes a fixed cover 5, a transmission cover 17, and an extension cover 18 disposed on the outer wall of the adapter ring 4. The fixed cover 5 is threadedly connected to the adapter ring 4. The outer walls of the transmission cover 17 and the extension cover 18 are provided with evenly distributed guide grooves 20 and evenly distributed positioning holes 22. The retractable protective assembly plays a protective and buffering role when the lens is dropped, reducing direct damage to the lens. The protective assembly is threadedly connected to the adapter ring 4 through the fixed cover 5, which is convenient for disassembly and replacement, reducing maintenance costs.

[0041] The positioning component is located on the outer wall of the strong spring B24, and the positioning component cooperates with the retractable protective component.

[0042] The locking anti-fall-off component is set on the inner wall of the slide groove 13.

[0043] like Figure 9As shown, in a preferred embodiment, based on the above method, the temperature drift adaptive calibration component further includes a T-shaped block 27 symmetrically slidably connected to the outer wall of the adapter ring 4. A docking ring 25 is fixedly connected to the outer wall of the T-shaped block 27, and the docking ring 25 is threadedly connected to the optical lens body 6. A symmetrically distributed shape memory alloy bracket 28 is fixedly connected to the outer wall of the docking ring 25. A heat-conducting rod 29 is fixedly connected to the end of the shape memory alloy bracket 28 away from the docking ring 25. A heat insulation cover 31 is fixedly connected to the outer wall of the heat-conducting rod 29. A heating ring 32 is fixedly connected to the inner wall of the heat insulation cover 31, and the heating ring 32 is fixedly connected to the heat-conducting rod 29. A uniformly distributed extrusion rod 30 is fixedly connected to the outer wall of the heat insulation cover 31, and the end of the extrusion rod 30 away from the heat insulation cover 31 abuts against the outer wall of the pressure ring 26. A control chip 33 is fixedly connected to the outer wall of the heat insulation cover 31. The outer wall of the control chip 33 is electrically connected to the heating ring 32. When the ambient temperature changes, the shape memory alloy bracket 28 adapts to the temperature change and deforms accordingly, thereby adjusting the position of the docking ring 25, that is, adjusting the position of the optical lens body 6. If the adaptive position is not appropriate, the control chip 33 automatically starts the heating ring 32 according to the preset program. The heat generated by the heating ring 32 is transferred to the shape memory alloy bracket 28 through the heat conduction rod 29. The shape memory alloy bracket 28 will deform with the temperature change, causing the docking ring 25 to slide along the T-block 27, thereby fine-tuning the position of the optical lens body 6. At the same time, the heat insulation cover 31 reduces heat loss and prevents heat energy from affecting the optical imaging inside the lens, ensuring that the heat energy is effectively applied to the shape memory alloy bracket 28. The cooperation between the compression rod 30 and the pressure ring 26 limits the range of heat transfer, making the adjustment process more precise.

[0044] like Figures 7-8 As shown, in a preferred embodiment, based on the above method, the positioning component further includes a strong spring B24 that is uniformly and fixedly connected to the outer walls of the fixed cover 5 and the transmission cover 17. A positioning ball 23 is fixedly connected to the outer wall of the strong spring B24, and the positioning ball 23 is located on the inner wall of the positioning hole 22. Under the action of the strong spring B24, the positioning ball 23 is inserted into the positioning hole 22 at different positions to realize the telescopic positioning of the protective component.

[0045] like Figure 6 As shown, in a preferred embodiment, based on the above method, the locking anti-detachment component further includes a slider 14 slidably connected to the inner wall of the slide groove 13, a locking ring 3 fixedly connected to the outer wall of the slider 14, uniformly distributed pressing blocks 12 fixedly connected to the outer wall of the locking ring 3, and uniformly distributed conical push blocks 16 fixedly connected to the outer wall of the locking ring 3. The conical push blocks 16 have strong friction, which facilitates pushing the locking ring 3 to move, thereby facilitating the disassembly of the adapter ring 4.

[0046] like Figure 6As shown, in a preferred embodiment, based on the above method, a strong spring A15 is fixedly connected to the outer wall of the slider 14, and the end of the strong spring A15 away from the slider 14 is fixedly connected to the slide groove 13. The strong spring A15 can push the slider 14 to drive the locking ring 3 to move towards the card plate 10 at all times, that is, the pressing block 12 always presses the protrusion block 11, and the card plate 10 moves, thereby achieving the locking effect of the card block 9.

[0047] like Figure 4 As shown, in a preferred embodiment, based on the above method, a triangular groove 8 is further provided between the lens mount 2 and the card plate 10, and the triangular groove 8 provides movable space for the card plate 10.

[0048] like Figure 2 As shown, in a preferred embodiment, based on the above method, a pressure ring 26 is fixedly connected to the inner wall of the lens mount 2, and a photosensitive film 7 is fixedly connected to the outer wall of the pressure ring 26. The photosensitive film 7 is used in conjunction with the optical lens body 6. After refraction by the optical lens body 6, the light signal is focused and imaged on the surface of the photosensitive film 7. The photosensitive element converts the light signal into an electrical signal and transmits it to the image processor.

[0049] like Figure 7 As shown, in a preferred embodiment, based on the above method, a light shield 19 is further connected to the outer wall of the extended shield 18 by threads. The light shield 19 is used to reduce stray light entering the lens, thereby reducing stray light entering the lens and improving image quality.

[0050] like Figure 7 As shown, in a preferred embodiment, based on the above method, both the transmission cover 17 and the outer wall of the fixed cover 5 are fixedly connected with uniformly distributed guide blocks 21, and the guide blocks 21 are slidably connected with the guide groove 20. The transmission cover 17 and the extension cover 18 are slidably connected through the guide blocks 21 and the guide groove 20. When it is necessary to adapt to lenses of different lengths, the extension of each cover is achieved by sliding the guide blocks 21 in the guide groove 20.

[0051] like Figure 4 As shown, in a preferred embodiment, based on the above method, a protrusion 11 is fixedly connected to the outer wall of the card plate 10, and the outer wall of the protrusion 11 abuts against the outer wall of the extrusion block 12.

[0052] Specifically, in use, the lens mount 2 achieves quick engagement with the adapter ring 4 via the locking plate 10 and locking block 9. During installation, the locking plate 10 is aligned with the slot of the adapter ring 4 and rotated. The locking block 9 engages with the slot, completing the initial connection. Subsequently, the locking ring 3 slides upward under the action of the strong spring A15, causing the pressing block 12 to press against the protrusion 11 on the locking plate 10, further securing the locking plate 10 to the adapter ring 4. At the same time, the tapered push block 16 prevents the locking plate 10 from moving in the opposite direction, achieving an anti-dislodgement function. During disassembly, only... By pushing the conical pusher 16, the locking ring 3 can be driven to slide within the slide groove 13 via the slider 14. Then, the adapter ring 4 can be pulled out forcefully. The fixed cover 5 is threadedly connected to the adapter ring 4. The transmission cover 17 and the extension cover 18 are slidably connected via the guide block 21 and the guide groove 20. When different lens lengths need to be accommodated, the extension cover 18 is pulled, and the positioning ball 23, under the action of the strong spring B24, engages with the positioning hole 22 at different positions, achieving the telescopic positioning of the protective assembly. The telescopic protective assembly protects the lens in case of a drop. The shape memory alloy bracket 28 acts as a protective buffer, reducing direct damage to the lens. The light shield 19 reduces stray light entering the lens, improving image quality. The protective components are connected to the adapter ring 4 by a fixed cover 5, facilitating disassembly and replacement and reducing maintenance costs. When the ambient temperature changes, the shape memory alloy bracket 28 adapts to the temperature change, thereby adjusting the position of the docking ring 25, i.e., adjusting the position of the optical lens body 6. If the adaptive position is not appropriate, the control chip 33 automatically activates the heating ring 32 according to the preset program. The heat generated by the heating ring 32 is transferred to the shape memory alloy bracket 28 through the heat conduction rod 29. The shape memory alloy bracket 28 will deform with the temperature change, causing the docking ring 25 to slide along the T-block 27, thereby fine-tuning the position of the optical lens body 6. At the same time, the heat shield 31 reduces heat loss and prevents heat energy from affecting the optical imaging inside the lens, ensuring that the heat energy is effectively applied to the shape memory alloy bracket 28. The cooperation between the compression rod 30 and the pressure ring 26 limits the range of heat transfer, making the adjustment process more precise.

[0053] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
