Description

[0001] The present invention relates to the technical field of optical equipment, in particular to a CPL filter with an adjustment function. Background Art

[0002] In the field of photographic equipment, especially in outdoor shooting or special environments such as underwater shooting and skiing, polarizing filters are needed to reduce reflected light and improve picture quality. Among them, CPL polarizing filter is a commonly used polarizing filter. It can effectively eliminate reflections, improve color saturation and contrast, and make the picture clearer and more natural.

[0003] Existing, traditional CPL polarizing filters usually do not have an adjustment function and cannot be adjusted according to actual needs. This has limited the application range of CPL polarizing filters to a certain extent. Most existing CPL polarizing filters are adjusted by manually rotating the filter to change its polarization angle. However, this method does not have an automatic adjustment function, is complicated to operate, and cannot automatically adjust according to changes in actual ambient light. It is not convenient for quick adjustment. In addition, the accuracy of manual adjustment is not high and errors are prone to occur, which can easily lead to unsatisfactory picture effects, thereby reducing the practicality of CPL polarizing filters.

[0004] Therefore, we propose a CPL filter with adjustment function to solve the above problems. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0033] Example 1

[0034] See also Figure 1-10 The present invention provides a technical solution: a CPL filter with an adjustment function, comprising a camera body 1, a mounting shaft 2 being provided on the outer surface of the camera body 1, an automatic adjustment component 4 being provided on the outer surface of the mounting shaft 2, the automatic adjustment component 4 comprising a threaded tube 401, a limiting groove 402 being provided on one side of the outer surface of the threaded tube 401, a gear ring 403 being rotatably connected to the inner surface of the limiting groove 402, a connecting ring 404 being fixed to the outer surface of the gear ring 403, a plurality of first electromagnets 405 being provided on the outer surface of the connecting ring 404, a connecting frame 406 being fixedly connected to the bottom of the threaded tube 401, and a forward and reverse motor 4 being provided on the inner wall of the connecting frame 406. 07, the output shaft of the forward and reverse motor 407 is fixedly connected to the rotating shaft 408, the outer surface of the rotating shaft 408 is fixedly sleeved with a driving gear 409, the outer surface of the other side of the threaded tube 401 is provided with a rotating groove 410, the inner part of the rotating groove 410 is rotatably connected to a rotating block 411, the outer surface of the rotating block 411 is provided with a CPL filter body 412, the outer surface of the CPL filter body 412 is fixed with multiple mounting brackets 413, the relative inner walls of the multiple mounting brackets 413 are provided with sliding grooves 414, the inner parts of each relative two sliding grooves 414 are slidably connected with a slider 415, the inner walls of the multiple sliding grooves 414 are provided with dampers 416, and the multiple dampers Springs 417 are provided on the outer surfaces of the dampers 416. A movable rod 418 is fixed to the outer surfaces of one side of the plurality of sliders 415. A first iron block 419 is fixedly mounted on one end of each of the movable rods 418. A light sensor 3 for detecting light intensity is provided on the outer surface of the camera body 1. A movable rod 420 is fixed to the outer surfaces of the other sides of the plurality of sliders 415. A second iron block 421 is fixed to one end of each of the movable rods 420. A plurality of mounting rods 422 are fixed to the outer surface of the threaded tube 401. A collar 423 is fixedly connected between one end of each of the mounting rods 422. A second electromagnet 424 is provided on the outer surface of the collar 423. The inner wall of the threaded tube 401 is threadedly connected to the outer surface of the mounting shaft 2, one end of the rotating shaft 408 is movably embedded in the outer surface of the driving gear 409 and meshed with the outer surface of the gear ring 403, one end of the multiple dampers 416 are respectively fixedly connected to the outer surfaces of the multiple sliders 415, one end of the multiple springs 417 are respectively fixedly connected to the outer surfaces of the multiple sliders 415, the other ends of the multiple springs 417 are respectively fixedly connected to the inner walls of the slide groove 414, one end of the multiple moving rods 418 are respectively movably penetrated to the outside of the multiple mounting brackets 413, and one end of the multiple movable rods 420 are respectively movably penetrated to the outside of the multiple mounting brackets 413.

[0035] In this embodiment, when the camera is in use and the CPL filter is needed to adjust the quality of the captured image, the threaded tube 401 is first sleeved on the surface of the mounting shaft 2, and the threaded tube 401 is rotated so that the threaded tube 401 and the mounting shaft 2 are threadedly connected, thereby fixing the threaded tube 401 on the outer surface of the camera body 1, and then fixing the CPL filter body 412 on the outer surface of the camera body 1. When the camera body 1 is in use, the light sensor 3 is turned on, wherein the light sensor 3 includes a light-sensitive material, such as a photodiode or a photoresistor, etc. When light is irradiated on these sensitive materials, the light sensor 3 is turned on. When light is applied to a material, it will cause changes in the electronic state inside the material. Taking a photoresistor as an example, in a dark environment, its resistance value is high. When there is light, the photon energy excites the electrons inside the material, making its conductivity enhanced and the resistance value reduced. By measuring the voltage or current changes at both ends of the photoresistor, the change in ambient light intensity can be indirectly reflected. When the light sensor 3 detects that the ambient light is too high and the image saturation needs to be increased, the forward and reverse motors 407 are first started to drive the shaft 408 to rotate, and then drive the driving gear 409 to rotate, and the driving gear 409 drives the gear ring 403 to rotate, wherein, as Figure 4 As shown, the inner wall of the gear ring 403 has a raised ring, the purpose of which is to facilitate the connection between the gear ring 403 and the limiting groove 402, and to limit the gear ring 403 while facilitating its rotation. Then, the multiple first electromagnets 405 are electrically connected to an external power supply to generate a magnetic field, so that the multiple first iron blocks 419 move toward the multiple first electromagnets 405 under the action of the magnetic force, thereby driving the multiple moving rods 418 to move toward the first electromagnets 405, and then extending the multiple springs 417. Under the attraction of the magnetic force, when the gear ring 403 rotates, it drives the multiple first electromagnets 405 to rotate, and then drives the CPL filter body 412 to rotate, wherein, as shown in FIG. Figure 6 As shown, the cross section of the rotating block 411 matches the internal cross section of the rotating groove 410, and both are T-shaped. The purpose is to limit the CPL filter body 412 while facilitating its rotation. When the light sensor 3 detects that the quality of the picture captured by the camera body 1 reaches the required quality, it transmits a signal to the external control device, and the forward and reverse motor 407 is turned off by the external control device. Conversely, when the saturation of the captured picture needs to be reduced, the forward and reverse motor 407 is started in the reverse direction to drive the CPL filter body 412 to rotate in the opposite direction. Through the action of the automatic adjustment component 4, the CPL filter body 412 can automatically adjust the saturation of the camera according to the intensity of the external light. Since the light sensor 3 is more sensitive to the intensity value of the external light, the CPL filter body 412 can be accurately rotated to the required position, thereby improving the quality of the picture captured by the camera body 1. This solves the problem in the prior art that the existing CPL filter does not have an automatic adjustment function, which reduces the practicality of the CPL polarizing filter.

[0036] Example 2

[0037] like Figure 1 and Figure 3-9 The outer surface of the camera body 1 is provided with a light sensor 3 for detecting light intensity. The outer surface of the other side of the multiple sliders 415 is fixed with a movable rod 420. One end of the multiple movable rods 420 is fixed with a second iron block 421. The outer surface of the threaded tube 401 is fixed with multiple mounting rods 422. One end of the multiple mounting rods 422 is fixedly connected with a collar 423. The outer surface of the collar 423 is provided with a second electromagnet 424. The inner wall of the threaded tube 401 is threadedly connected to the outer surface of the mounting shaft 2. One end of the rotating shaft 408 is movable. The outer surface of the driving gear 409 is movably embedded in the meshing connection with the outer surface of the gear ring 403, one end of the plurality of dampers 416 is fixedly connected to the outer surfaces of the plurality of sliders 415, one end of the plurality of springs 417 is fixedly connected to the outer surfaces of the plurality of sliders 415, the other ends of the plurality of springs 417 are fixedly connected to the inner wall of the slide groove 414, one end of the plurality of moving rods 418 is movably passed through the outside of the plurality of mounting brackets 413, and one end of the plurality of movable rods 420 is movably passed through the outside of the plurality of mounting brackets 413.

[0038] In this embodiment, since the camera body 1 is often used for external shooting and the external environment is changeable, when the CPL filter body 412 is rotated to a required angle, since most of the forward and reverse motors 407 on the existing market do not have a self-locking function, the positioning effect is relatively poor. In order to prevent the CPL filter body 412 from being shifted due to external collisions and affecting the shooting effect, the multiple first electromagnets 405 are first disconnected from the external power supply, so that the multiple first iron blocks 419 are no longer attracted by the external magnetic field and are reset under the elastic action of the spring 417. Then, the second electromagnet 424 is electrically connected to the external power supply to generate a magnetic field, so that the multiple second iron blocks 421 are affected by the magnetic force and move toward the second electromagnet 424, so that they are tightly connected to the second electromagnet 424. Then, the multiple second iron blocks 421 are fixed, and thus the CPL filter body 412 is fixed, effectively preventing the CPL polarizing filter from being shifted due to external collisions.

[0039] Example 3

[0040] like Figure 1 and Figure 10A cleaning assembly 5 is provided on the outer surface of the collar 423. The cleaning assembly 5 includes an auxiliary frame 501. The outer surface of the auxiliary frame 501 is fixedly connected to the outer surface of the collar 423. A driving motor 502 is provided on the inner wall of one side of the auxiliary frame 501. The output shaft of the driving motor 502 is fixedly connected to a connecting shaft 503. One end of the connecting shaft 503 is movably embedded in the inner wall of the other side of the auxiliary frame 501. A supporting frame 504 is fixedly sleeved on the outer surface of the connecting shaft 503. A multi-stage electric telescopic rod 505 is provided on the outer surface of the supporting frame 504.

[0041] In this embodiment, when the light sensor 3 detects that dirt appears on the surface of the CPL filter body 412, the driving motor 502 is first started to drive the connecting shaft 503 to rotate, and then drive the supporting frame 504 to rotate. At the same time, the multi-stage electric telescopic rod 505 is started to extend and retract back and forth, driving the moving block 506 to move back and forth, and then driving the sponge block 507 to move back and forth. Through the rotation of the supporting frame 504, the sponge block 507 wipes the outer surface of the CPL filter body 412 back and forth until the dirt on the surface of the CPL filter body 412 is cleaned. When the surface of the CPL filter body 412 is cleaned, the driving motor 502 is turned off, and then the multi-stage electric telescopic rod 505 is shortened to the shortest, so that the light of the CPL filter body 412 can pass through the filter more accurately, reducing scattering, blurring, etc. caused by dirt, and making the captured picture clearer and sharper.

[0042] The method of using the device and the working principle are as follows: when it is necessary to use the CPL filter to adjust the quality of the captured image, firstly, the threaded tube 401 is sleeved on the surface of the mounting shaft 2, and the threaded tube 401 is rotated so that the threaded tube 401 and the mounting shaft 2 are threadedly connected, thereby fixing the threaded tube 401 on the outer surface of the camera body 1, and then fixing the CPL filter body 412 on the outer surface of the camera body 1, and then turning on the light sensor 3. When the light sensor 3 detects that the ambient light is too high and the image saturation needs to be increased, firstly the forward and reverse motors 407 are started to drive the rotating shaft 408 to rotate, and then the driving gear 409 is driven to rotate, and the driving gear 409 drives the gear ring 403 to rotate, and then the plurality of first electromagnets 405 are electrically connected to the external power supply to generate. A magnetic field is generated, so that the multiple first iron blocks 419 move toward the multiple first electromagnets 405 respectively under the action of the magnetic force, thereby driving the multiple moving rods 418 to move toward the first electromagnets 405, and then causing the multiple springs 417 to extend. Under the attraction of the magnetic force, when the gear ring 403 rotates, the multiple first electromagnets 405 are driven to rotate, and then the CPL filter body 412 is driven to rotate. When the light sensor 3 detects that the quality of the picture captured by the camera body 1 reaches the required quality, the signal is transmitted to the external control device, and the forward and reverse motors 407 are turned off by the external control device. Conversely, when the saturation of the captured picture needs to be reduced, the forward and reverse motors 407 are started in the reverse direction to drive the CPL filter body 412 to rotate in the reverse direction. Since the camera body 1 is often used for external shooting and the external environment is changeable, when the CPL filter body 412 is rotated to a required angle, since most of the forward and reverse motors 407 on the existing market do not have a self-locking function, the positioning effect is relatively poor. In order to prevent the external collision from causing the position of the CPL filter body 412 to shift and affect the shooting effect, the multiple first electromagnets 405 are first disconnected from the external power supply, so that the multiple first iron blocks 419 are no longer attracted by the external magnetic field and are reset under the elastic action of the spring 417. Then, the second electromagnet 424 is electrically connected to the external power supply to generate a magnetic field, so that the multiple second iron blocks 421 are affected by the magnetic force and move toward the direction of the second electromagnet 424, thereby tightly contacting the second electromagnet 424. The iron 424 is tightly connected, thereby fixing the multiple second iron blocks 421, thereby fixing the CPL filter body 412. When the light sensor 3 detects that there is dirt on the surface of the CPL filter body 412, the driving motor 502 is first started to drive the connecting shaft 503 to rotate, thereby driving the carrier 504 to rotate, and at the same time starting the multi-stage electric telescopic rod 505 to stretch back and forth, driving the moving block 506 to move back and forth, and then driving the sponge block 507 to move back and forth. Through the rotation of the carrier 504, the sponge block 507 wipes the outer surface of the CPL filter body 412 back and forth until the dirt on the surface of the CPL filter body 412 is cleaned. When the surface of the CPL filter body 412 is cleaned, the driving motor 502 is turned off.The multi-stage electric telescopic rod 505 is then retracted to its shortest position. The external control device is electrically connected to the camera body 1, the light sensor 3, the first electromagnet 405, the forward and reverse motor 407, the second iron block 421, the second electromagnet 424, the drive motor 502, and the multi-stage electric telescopic rod 505.

Its working principle is a well-known technology, and its model is selected according to actual use. Therefore, the control method and wiring layout of the camera body 1, photosensor 3, first electromagnet 405, forward / reverse motor 407, second iron block 421, second electromagnet 424, drive motor 502, and multi-stage electric telescopic rod 505 will not be explained in detail.
