Description

Technical Field

[0001] This invention relates to the field of lens aperture technology, and more specifically to an electromagnetically driven lens aperture adjustment device. Background Technology

[0002] Electromagnetically driven lens aperture adjustment mechanisms use an electromagnetic actuator to drive a rotating carrier, which in turn pushes a guide rod. The guide rod then rotates the aperture blades, and multiple stacked aperture blades rotate synchronously around the rotating rod. The guide rod moves along the track, thus adjusting the aperture opening to control the amount of light entering the lens. Existing lens aperture adjustment mechanisms typically consist of a lens, lens cap, electromagnetic actuator, rotating carrier, track, aperture blades, guide rod, rotating rod, and a fixed carrier. The lens cap has a transparent glass panel to allow light to enter.

[0003] The glass on the lens cap is prone to dust and stains, which affects light transmittance and image quality. It usually lacks an integrated cleaning mechanism, requiring staff to carry tools to clean the lens cap. The cleaning effect is not good, and the frequent movement between the guide rod and the track causes wear and tear, increasing frictional resistance and causing poor movement or even jamming. This affects the aperture adjustment accuracy and response speed. Regular lubrication and maintenance are required, but the usual maintenance methods are inefficient. Summary of the Invention

[0004] This invention provides an electromagnetically driven lens aperture adjustment device to solve the problems of difficulty in cleaning the lens cap glass and lack of convenient lubrication mechanism between the guide rod and the track in existing lens aperture adjustment devices.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

A rotating carrier is connected to the electromagnetic actuator. Multiple tracks are evenly distributed on the rotating carrier. Multiple aperture blades are stacked on the rotating carrier, with one end of each aperture blade connected to a guide rod, which is guided to the tracks. The other end of each aperture blade is connected to a rotating rod. A fixed carrier is positioned above the stacked aperture blades. The rotating rods are rotatably connected to the fixed carrier and are evenly distributed. A glass element is provided on the lens cap. The device also includes:

[0007] The cleaning unit is rotatably disposed outside the electromagnetic actuator and located between the lens and the lens cap. It includes a rotatable support member that is rotatably connected to the electromagnetic actuator, and adjustable support members that are symmetrically disposed through the rotatable support member to facilitate swinging and cleaning the glass.

[0008] The lubrication section is provided on the cleaning section. It includes a storage and squeezing member for storing lubricating oil, which is provided in the spin support member. The storage and squeezing member cooperates with the support and friction member to squeeze the storage and squeezing member to discharge the lubricating oil. It also includes a discharge guide member provided above the spin support member for guiding the discharge of lubricating oil so as to lubricate the guide rod and the track.

[0009] Furthermore, it includes: symmetrically arranged and integrally formed support rods on the lens, the end of the support rods being detachably connected to the lens cap via a fixing component, and the lens cap being located outside the fixing carrier and aperture blades, and simultaneously connected to the fixing carrier via bolts.

[0010] Furthermore, the spindle support includes:

[0011] The bearing is located on the outside of the electromagnetic actuator;

[0012] A swivel ring is fixed to the outside of the bearing.

[0013] The concave cavities are evenly and symmetrically located on the outer side of the spiral ring.

[0014] Furthermore, the friction support includes:

[0015] The guide sleeve is set inside the concave cavity and is fixedly connected to the rotating ring;

[0016] The connecting rod is movably connected at one end, passing through the guide sleeve;

[0017] The baffle is fixed to one end of the connecting rod and located inside the guide sleeve;

[0018] The adjusting parts are housed in the recessed cavity and connected to the other end of the connecting rod.

[0019] Furthermore, the adjusting component includes:

[0020] The arc plate is fixed to the other end of the connecting rod;

[0021] The opening is symmetrically designed to penetrate the curved plate.

[0022] A pull strap, which passes through the opening and connects to the curved plate, is used to pull the curved plate.

[0023] The clearance opening is located at the end of the arc plate furthest from the connecting rod.

[0024] The wiping component is located on the inside of the arc plate.

[0025] Furthermore, the wiping component includes:

[0026] Guide grooves are opened through the top and bottom surfaces of the arc plate;

[0027] A flexible plate is movably positioned on the inner side of the curved plate;

[0028] The sliding rod is symmetrically fixed to the flexible plate and extends to the inside of the guide groove;

[0029] The cotton brush is fixed to the side of the flexible plate away from the pull strip.

[0030] Furthermore, the storage component includes:

[0031] The capsule is located inside the concave cavity and is connected to the inner top wall of the cavity;

[0041] The above-described solution of the present invention has at least the following beneficial effects:

[0042] By incorporating a cleaning section and a lubrication section, the glass cleaning and track lubrication functions are integrated into the aperture adjustment device. The cleaning section uses a rotating ring to drive a cotton brush to wipe the glass, completing the cleaning without removing the lens cap or requiring personnel to carry tools. The lubrication section uses a capsule to store lubricant, which is then squeezed by the pressure plate and cotton brush to expel the lubricant into the track through a shaping hose and a throttling nozzle. This achieves an organic combination and synergistic effect of cleaning and lubrication functions, improving maintenance efficiency and ensuring the stability of optical and mechanical performance.

[0055] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0056] like Figures 1 to 10As shown, an embodiment of the present invention provides an electromagnetically driven aperture adjustment device for a lens 1, including a lens 1, a lens cap 10, and an electromagnetic driver 2 disposed on the lens 1. A rotating carrier 3 is connected to the electromagnetic driver 2. A plurality of tracks 4 are evenly distributed on the rotating carrier 3. A plurality of aperture blades 5 are stacked on the rotating carrier 3, and one end of each aperture blade 5 is connected to a guide rod 6, which is guided and connected to the track 4. The other end of each aperture blade 5 is connected to a rotating rod 7. A fixed carrier 12 is disposed above the stacked aperture blades 5. The rotating rod 7 is rotatably connected to the fixed carrier 12 and is evenly distributed. A glass 11 is disposed on the lens cap 10. The device also includes:

[0057] The cleaning unit is rotatably disposed outside the electromagnetic driver 2 and located between the lens 1 and the lens cover 10. It includes a rotatable support member rotatably connected to the electromagnetic driver 2 and adjustable support members symmetrically disposed through the rotatable support member to facilitate swinging and cleaning the glass 11.

[0058] The lubrication section is provided on the cleaning section. It includes a storage and squeezing member for storing lubricating oil, which is provided in the spin support member. The storage and squeezing member cooperates with the support and friction member to squeeze the storage and squeezing member to discharge the lubricating oil. It also includes a discharge guide member provided above the spin support member for guiding the discharge of lubricating oil so as to lubricate the guide rod 6 and the track 4.

[0059] Specifically, the lens cover 10 has a symmetrically integrally formed support plate 9 on its outer side. The support plate 9 is connected to the support rod 8 through a fixing component. The lens 1 can provide stable support for the electromagnetic actuator 2. The electromagnetic actuator 2 can drive the rotating carrier 3 to rotate using electromagnetic force under the operation of the operator. The rotating carrier 3 can provide space for the track 4. The track 4 can provide a moving guide for the guide rod 6 and can push the aperture blades 5 through the guide rod 6. The lens 1 can be supported by the support plate 9 through the support rod 8 using the fixing component, so that the support plate 9 can stably support the lens cover 10. The lens cover 10 can provide stable support for the glass 11 and can cooperate with the glass 11 to provide protection for the aperture blades 5 and the lens 1.

[0060] In practical application, the staff can disassemble the fixing components of the fixing plate 9 according to the actual needs, and at the same time, disconnect the fixing components connected to the fixing carrier 12 and the lens cover 10, and then move the lens cover 10 upward so that the lens cover 10 drives the plate 9 to separate from the support rod 8, thereby opening the lens cover 10 to expose the fixing carrier 12 and the electromagnetic driver 2, which facilitates the staff to perform maintenance and other operations.

[0061] The staff can control the operation of the electromagnetic driver 2 according to the actual needs, so that the electromagnetic driver 2 uses electromagnetic force to drive the rotating carrier 3 to rotate at a certain angle. The rotating carrier 3 will use rotational power and track 4 to push the guide rod 6, so that the guide rod 6 pushes the aperture blade 5 to rotate around the rotating rod 7 under the support of the fixed carrier 12. At the same time, the guide rod 6 will move along the track 4 during the rotation of the rotating carrier 3 and the aperture blade 5, so that the multiple stacked aperture blades 5 can be moved synchronously, thereby achieving the function of adjusting the aperture size.

[0062] As a preferred embodiment of the present invention, the lens 1 is symmetrically provided with and integrally formed with a support rod 8. The end of the support rod 8 is detachably connected to the lens cover 10 through a fixing component. The lens cover 10 is located outside the fixing carrier 12 and the aperture blade 5, and is connected to the fixing carrier 12 by bolts.

[0063] A sealing gasket is provided between the lens cap 10 and the rotating ring 14;

[0064] The lens cap 10 and the rotating ring 14 are pressed together with the sealing gasket.

[0065] Specifically, the rotating ring 14 provides support for the sealing gasket, which is made of rubber and can deform under external force and rebound using rebound force. It fits against the lens cap 10 and the rotating ring 14 to achieve a sealing effect. The lens cap 10 provides stable support for the glass 11, which is made of transparent material, making it convenient for the lens 1 to take pictures and can provide a channel for light in conjunction with the aperture.

[0066] In practical application, after maintenance is completed, the lens cap 10 can be moved, causing the lens cap 10 to move along with the glass 11 and the support plate 9. The support plate 9 can then be placed on the support rod 8. The support plate 9 and the support rod 8 can then be securely connected using fixing components. As the fixing components tighten, the lens cap 10 can gradually press down on the sealing gasket, allowing the sealing gasket to cooperate with the lens cap 10 to provide sealing and protection under the support of the rotating ring 14. This also makes maintenance easier for the staff and reduces the difficulty of disassembly.

[0067] The spindle support includes:

[0068] Bearing 13 is located on the outside of electromagnetic actuator 2;

[0069] The rotating ring 14 is fixed to the outside of the bearing 13;

[0070] The concave cavity 15 is evenly and symmetrically opened on the outer side of the spiral ring 14.

[0071] Specifically, the electromagnetic actuator 2 can provide stable support for the bearing 13, the bearing 13 can provide rotational support for the rotating ring 14, the rotating ring 14 can provide opening space for the cavity 15, the cavity 15 can provide setting space for the guide sleeve 16, and can provide storage space for the arc plate 19, the flexible plate 24 and the cotton brush 26.

[0072] The friction support components include:

[0073] The guide sleeve 16 is disposed in the cavity 15 and is fixedly connected to the rotating ring 14;

[0074] Linkage 17 is movably connected to one end of guide sleeve 16;

[0075] The baffle 18 is fixed to one end of the connecting rod 17 and is located inside the guide sleeve 16;

[0076] The adjusting parts are housed in the cavity 15 and connected to the other end of the connecting rod 17.

[0077] Specifically, the guide sleeve 16 can provide rotational support for the connecting rod 17 under the support of the rotating ring 14, and can also provide movement guidance for the connecting rod 17. The connecting rod 17 can provide support for the stop plate 18, and the stop plate 18 can prevent the connecting rod 17 from completely moving out of the guide sleeve 16.

[0078] The friction adjustment parts include:

[0079] Arc plate 19 is fixed to the other end of connecting rod 17;

[0080] A 20-inch opening is provided, with symmetrical through-arch plates 19.

[0081] The pull strap 21 is connected to the arc plate 19 through the through opening 20 so as to pull the arc plate 19.

[0082] The clearance opening 23 is located at the end of the arc plate 19 away from the connecting rod 17;

[0083] The wiping component is located on the inside of the arc plate 19.

[0084] Specifically, the connecting rod 17 can stably support the arc plate 19, the arc plate 19 can provide opening space for the through port 20, and the arc plate 19 can provide opening space for the clearance port 23. The through port 20 can provide installation space for the pull strap 21. The pull strap 21 can easily pull the arc plate 19 to move. The clearance port 23 and the through port 20 can facilitate the workers to push the flexible plate 24 to move and deform.

[0085] Wiping components include:

[0086] The guide groove 22 is opened through the upper and lower surfaces of the arc plate 19;

[0087] The flexible plate 24 is movably set inside the arc plate 19;

[0088] The slide bar 25 is symmetrically fixed on the flexible plate 24 and extends to the inside of the guide groove 22;

[0089] The cotton brush 26 is fixed to the side of the flexible plate 24 away from the pull strap 21.

[0090] Specifically, the arc plate 19 provides space for the guide groove 22, the guide groove 22 provides movement guidance for the slide rod 25, and the slide rod 25 can rotate within the guide groove 22 under the action of external force. It also provides support for the flexible plate 24, which is flexible and can deform under the action of external force. When the external force disappears, it will rebound. Furthermore, it provides stable support for the cotton brush 26, which is elastic and can deform under the action of external force.

[0091] In practical application, the operator can loosen the fixing components of the support rod 8 and the support plate 9 as needed to relieve the pressure on the sealing gasket. Then, the operator can pull the arc plate 19 away from the center of the rotating ring 14 using the pull strap 21. This causes the arc plate 19 to drive the connecting rod 17, which in turn drives the baffle 18. The connecting rod 17 and the baffle 18 can then move along the guide sleeve 16 away from the center of the rotating ring 14. This allows the arc plate 19 to move out of the cavity 15 along with the flexible plate 24 via the slide rod 25. At the same time, the flexible plate 24 will move the cotton brush 26 out as well. The operator then needs to push the arc plate 19 counterclockwise, causing the arc plate 19 to drive the connecting rod 17 to rotate counterclockwise under the support of the guide sleeve 16. This allows the arc plate 19 to rotate and adjust the flexible plate 24 to an angle perpendicular to the lens 1. After that, the operator can pull the flexible plate 24 from the clearance opening 23, causing the flexible plate 24 to drive the slide rod. 25 moves along the guide groove 22 away from the connecting rod 17 to its limit, and then rotates the flexible plate 24, causing the flexible plate 24 to drive the sliding rod 25 to rotate together in the guide groove 22, so that the flexible plate 24 can rotate towards the glass 11, and thus the flexible plate 24 can drive the cotton brush 26 to rotate together, so that the cotton brush 26 is placed on the glass 11. Then the operator can push the rotating ring 14 back and forth, so that the rotating ring 14 rotates around the electromagnetic driver 2 with the support of the bearing 13. Thus, the rotating ring 14 can drive the arc plate 19 to swing back and forth around the bearing 13 through the guide sleeve 16 and the connecting rod 17. At the same time, the arc plate 19 will drive the flexible plate 24 through the sliding rod 25, so that the flexible plate 24 drives the cotton brush 26 to swing back and forth together, so that the cotton brush 26 can wipe the glass 11 during the swing, so as to prevent the dirt on the glass 11 from affecting the light entering the aperture, providing convenience for cleaning work, and eliminating the need for the operator to carry cleaning equipment.

[0092] In a preferred embodiment of the present invention, the storage and extrusion component includes:

[0093] Capsule 27 is disposed within cavity 15 and is connected to the inner top wall of the cavity;

[0094] The filling port 28 is opened above the capsule 27 and the spiral ring 14;

[0095] The stopper 29 is fitted inside the filling port 28.

[0096] Specifically, the rotating ring 14 provides stable support for the capsule 27, which can be squeezed and deformed under external force and will rebound when the external force is removed. The capsule 27 can also provide storage space for lubricant, and the stopper 29 can block the filling port 28, which allows lubricant to be easily added into the capsule 27.

[0097] The friction support components include:

[0098] Pull ring 30 is fixed to the upper end of stopper 29;

[0099] A shaping tube 31 is provided through the pull ring 30 and extends to the inner bottom wall of the capsule 27;

[0100] The throttling nozzle 32 is connected to the upper end of the shaping hose 31.

[0101] Specifically, the stopper 29 provides stable support for the pull ring 30 and provides a through channel for the shaping hose 31. The shaping hose 31 can be bent and deformed under external force and can be shaped. The shaping hose 31 also provides stable support for the throttling nozzle 32. The throttling nozzle 32 can reduce the amount of lubricant discharged from the shaping hose 31 and avoid excessive lubricant being discharged each time the capsule 27 is squeezed. The capsule 27 is made of transparent material, which allows the operator to easily observe the internal liquid level from the cavity 15. After pulling the arc plate 19 and the toughness plate 24 out of the cavity 15, the operator can observe the capsule 27 from the cavity 15 and judge the liquid level of the lubricant inside the capsule 27.

[0102] In practical application, according to the actual needs, the operator can unscrew the fixing parts of the fixing plate 9 and the support rod 8 to release the fixation of the lens cap 10. Then, the lens cap 10 can be removed, exposing the upper end of the rotating ring 14. Then, the stopper 29 can be pulled vertically upward through the pull ring 30 to pull the stopper 29 out of the filling port 28, thereby opening the filling port 28. Then, the lubricant can be drawn up with a syringe and injected into the capsule 27 from the filling port 28 for storage. After that, the stopper 29 is put back into the filling port 28, and the... The arc plate 19 and the flexible plate 24 are reset and moved into the recess 15 for storage. After prolonged use of the aperture adjustment device, the flexible plate 24 can be squeezed from the opening 20 or the clearance opening 23 using tools such as a pressure rod, causing the flexible plate 24 to move closer to the capsule 27 under external force, thereby deforming the flexible plate 24. Under the action of external force and the resistance of the capsule 27, the cotton brush 26 can be squeezed, causing the cotton brush 26 to be squeezed and deformed to its limit. Then, the flexible plate 24 is squeezed further, so that the flexible plate 24 and the cotton brush squeezed to its limit are squeezed together. 26. With further compression of capsule 27, capsule 27 can be deformed under external force. At the same time, the operator can bend the shaping hose 31 as needed, so that the shaping hose 31 drives the throttling nozzle 32 to bend and adjust its position, so that the discharge end of the throttling nozzle 32 can be aligned with the track 4. After capsule 27 is squeezed, the pressure will squeeze the lubricant stored inside, so that the lubricant is squeezed into the shaping hose 31 and flows into the throttling nozzle along the shaping hose 31, and finally passes through the throttling nozzle and is discharged into the track 4. At the same time, the operator can push the rotating ring 14 to rotate under the support of bearing 13, so that the rotating ring 14 can drive capsule 27, plug 29, shaping hose 31 and throttling nozzle to rotate and adjust their positions together, so that the throttling nozzle can discharge lubricant into the track 4 at different positions. At the same time, the use of multiple capsules 27 allows the aperture adjustment device to perform multiple lubricant filling operations, which makes it convenient for the operator to add lubricant to the track 4 that provides movement guidance for the aperture blades 5 for maintenance, thereby improving maintenance efficiency.

[0103] Working principle:

[0104] The electromagnetic actuator 2 drives the rotating carrier 3 to rotate. The track 4 on the rotating carrier 3 pushes the guide rod 6. The guide rod 6 pushes the aperture blades 5 to rotate around the rotating rod 7. The guide rod 6 moves synchronously along the track 4, so that multiple aperture blades 5 are displaced in coordination to achieve aperture size adjustment.

[0105] Pulling the arc plate 19 with the pull strap 21 causes the connecting rod 17 to move along the guide sleeve 16, which in turn moves the flexible plate 24 and the cotton brush 26 out of the cavity 15. After adjusting the angle of the flexible plate 24 and bringing the cotton brush 26 into contact with the glass 11, the rotating ring 14 is pushed back and forth. The rotating ring 14 rotates under the support of the bearing 13, which drives the arc plate 19 to swing back and forth through the connecting rod 17. The cotton brush 26 swings accordingly to wipe the glass 11.

[0106] Lubricant is injected into capsule 27 through filling port 28. When lubrication is needed, the flexible plate 24 is squeezed through opening 20 or relief port 23. The flexible plate 24, in conjunction with the cotton brush 26, squeezes capsule 27. Under pressure, the lubricant inside capsule 27 flows through shaping hose 31 into throttling nozzle 32 and is discharged into track 4. The nozzle position can be adjusted by bending shaping hose 31 or rotating ring 14.

[0107] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
