Description
Technical Field
[0001] This utility model relates to the field of shutter system applications, specifically a shutter device with strong light adaptive processing. Background Technology
[0002] The shutter system is a mechanism in a camera or photographic device used to control exposure time. It determines the length of time the camera sensor (or film) is exposed to light, thus affecting the brightness, sharpness, and motion blur effect of the photograph.
[0003] Shutter systems are mainly divided into mechanical shutters and electronic shutters. A mechanical shutter is a shutter system that uses a mechanical device to control the time when the camera sensor (or film) is exposed to light. It usually consists of multiple shutter curtains or shutter blades. The shutter opens and closes through a mechanical structure, thereby controlling the time when light enters the camera.
[0004] Mechanical shutters have a shorter response time than electronic shutters and do not have the delay that electronic shutters may have. However, due to the impact of multiple shutter curtains, mechanical shutter systems are usually noisier, especially during continuous fast shooting. Furthermore, because they are mechanical, prolonged use may cause wear and tear on the shutter system, affecting its lifespan. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a shutter device with strong light adaptive processing to solve the technical problems mentioned in the background.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shutter device with strong light adaptive processing, comprising a support plate, a movable ring rotatably connected to the top of the support plate, an outer gear ring provided on the outer side of the movable ring, and an inner gear ring provided on the inner side of the movable ring, a transmission tooth rotatably connected to one side of the movable ring, the transmission tooth meshing with the outer gear ring, and the transmission tooth connected to a drive device, a shutter assembly provided on the top of the support plate, the shutter assembly comprising a base plate and a cover plate, a curtain movably mounted on the top of the base plate, and racks provided on both sides of the curtain, and the two sets of racks and the inner gear ring being connected by a first gear set and a second gear set for transmission.
[0007] By adopting the above technical solution, the use of multiple shutter assemblies stacked together can avoid the curtains colliding with each other and reduce the noise of the shutter system during operation. Each shutter assembly contains only one curtain, and four shutter assemblies are stacked from top to bottom. The four curtains within the four shutter assemblies are evenly distributed with the exposure hole as the center. Thus, when the multiple curtains move, they can block the exposure hole. Furthermore, since the multiple curtains are at different horizontal heights, they will not collide with each other, reducing the mechanical noise generated during the operation of the shutter system.
[0008] The present invention is further configured such that the cover plate is disposed on the top of the base plate, and the base plate and the cover plate are fixed together by screws.
[0009] Preferably, the base plate and cover plate are fixed with screws, allowing them to be disassembled for easy maintenance later.
[0010] The present invention is further configured such that limit rods are provided on both sides of the curtain, and limit grooves matching the limit rods are opened on the sides of the bottom plate and the cover plate.
[0011] Preferably, by setting limiting rods on both sides of the curtain, the curtain can be movably installed between the base plate and the cover plate through the limiting rods and limiting grooves, thereby reducing the friction between the curtain and the base plate and cover plate and reducing the wear of the components.
[0012] The present invention is further configured such that the first gear set and the second gear set are disposed on the top of the base plate, and the first gear set meshes with the rack on one side of the curtain, and the second gear set meshes with the rack on the other side of the curtain.
[0013] Preferably, by setting the first gear set and the second gear set to drive the movement of the curtain simultaneously, the operation of the curtain is more stable and smooth, and the wear between components can be reduced.
[0014] The present invention is further configured such that the first gear set and the internal gear ring mesh with each other, and the second gear set and the internal gear ring mesh with each other.
[0015] Preferably, by setting up a first gear set and a second gear set, the rotation of the internal gear ring drives the first gear set and the second gear set to drive the curtain movement.
[0016] The present invention is further configured such that the top outer wall of the curtain and the cover plate do not contact each other, and the bottom outer wall of the curtain and the bottom plate do not contact each other.
[0017] Preferably, the curtain is movably installed between the base plate and the cover plate via a limiting rod and a limiting groove, thereby reducing the friction between the curtain and the base plate and the cover plate, and reducing the wear of the components.
[0018] The present invention is further configured such that an exposure hole is provided at the middle position of both the base plate and the cover plate.
[0019] Preferably, by setting an exposure hole, external light can pass through the shutter system, thereby controlling the shutter system and thus controlling the exposure.
[0020] The present invention is further configured such that a through hole matching the exposure hole is opened on the top of the carrier plate.
[0021] Preferably, through holes are provided on the support plate to allow external light to enter the device.
[0022] The present invention is further configured such that the shutter assembly is provided in multiple sets, and the multiple sets of shutter assemblies are distributed sequentially from top to bottom.
[0023] Preferably, multiple shutter assemblies are arranged sequentially from top to bottom to prevent the curtains of the multiple shutter assemblies from colliding with each other.
[0024] The present invention is further configured such that multiple sets of shutter components are evenly distributed with the exposure hole as the center.
[0025] Preferably, multiple shutter assemblies are evenly distributed around the exposure hole, so that the curtains of the multiple shutter assemblies can move closer to each other to adjust the size of the exposure hole.
[0026] In summary, the present invention has the following main advantages:
[0027] 1. This utility model avoids the collision between curtains by setting multiple sets of shutter components stacked together, thereby reducing the noise of the shutter system during operation. Each set of shutter components contains only one set of curtains. At the same time, four sets of shutter components are stacked from top to bottom, and the four sets of curtains in the four sets of shutter components are evenly distributed with the exposure hole as the center. Thus, when the multiple sets of curtains move, they can achieve the purpose of blocking the exposure hole. Moreover, since the multiple sets of curtains are at different horizontal heights, the multiple sets of curtains will not collide with each other, thereby reducing the mechanical noise generated during the operation of the shutter system.
[0028] 2. This utility model sets up multiple sets of curtains at different horizontal heights to block the exposure holes. As a result, even if the mechanical parts wear out during long-term use, the multiple sets of curtains will not collide with each other. When the multiple sets of curtains move independently and do not collide with each other, the wear caused by the impact vibration between mechanical parts can also be reduced, thereby extending the service life of the shutter system.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0037] The embodiments of this utility model will be described below based on its overall structure.
[0038] Please see Figure 1 - Figure 5 A shutter device with strong light adaptive processing includes a carrier plate 1. A movable ring 2 is rotatably connected to the top of the carrier plate 1. An outer gear ring 3 is provided on the outer side of the movable ring 2, and an inner gear ring 4 is provided on the inner side of the movable ring 2. A transmission gear 5 is rotatably connected to one side of the movable ring 2, and the transmission gear 5 meshes with the outer gear ring 3. A driving device is connected to the transmission gear 5. The driving device is controlled by a light sensor, such as a photodiode (BPW34) or a CMOS image sensor (GL5516), and adjusts the shutter speed according to the light intensity. The dynamic adjustment drive device drives the rotation speed of the transmission gear 5, thereby controlling the operating speed of the shutter system. The top of the support plate 1 is provided with a shutter assembly 6, which includes a base plate 601 and a cover plate 602. A curtain 604 is movably installed on the top of the base plate 601. The movement of the curtain 604 is used to control the size of the exposure hole 7, thereby controlling the exposure time. Both sides of the curtain 604 are provided with racks 606, and the two sets of racks 606 and the internal gear ring 4 are connected by a first gear set 603 and a second gear set 608.
[0039] Please refer to the above embodiments for further details. Figure 2 The cover plate 602 is located on top of the base plate 601, and the base plate 601 and the cover plate 602 are fixed together by screws. By fixing the base plate 601 and the cover plate 602 with screws, the base plate 601 and the cover plate 602 can be disassembled for later maintenance.
[0040] Please refer to the above embodiments for further details. Figure 4and Figure 5 Limiting rods 605 are provided on both sides of the curtain 604. Limiting grooves 607 matching the limiting rods 605 are opened on the sides of the base plate 601 and the cover plate 602. By providing limiting rods 605 on both sides of the curtain 604, the curtain 604 can be movably installed between the base plate 601 and the cover plate 602 through the limiting rods 605 and the limiting grooves 607, thereby reducing the friction between the curtain 604 and the base plate 601 and the cover plate 602 and reducing the wear of the components.
[0041] Please refer to the above embodiments for further details. Figure 4 The first gear set 603 and the second gear set 608 are disposed on the top of the base plate 601. The first gear set 603 meshes with the rack 606 on one side of the curtain 604, and the second gear set 608 meshes with the rack 606 on the other side of the curtain 604. By setting the first gear set 603 and the second gear set 608 to drive the movement of the curtain 604 simultaneously, the operation of the curtain 604 is more stable and smooth, which can reduce the wear between components.
[0042] Please refer to the above embodiments for further details. Figure 4 The first gear set 603 meshes with the internal gear ring 4, and the second gear set 608 meshes with the internal gear ring 4. By setting the first gear set 603 and the second gear set 608, the rotation of the internal gear ring 4 drives the first gear set 603 and the second gear set 608 to drive the curtain 604 to move.
[0043] Please refer to the above embodiments for further details. Figure 3 The top outer wall of the curtain 604 does not contact the cover plate 602, and the bottom outer wall of the curtain 604 does not contact the base plate 601. The curtain 604 is movably installed between the base plate 601 and the cover plate 602 through the limiting rod 605 and the limiting groove 607, which reduces the friction between the curtain 604 and the base plate 601 and the cover plate 602 and reduces the wear of the components.
[0044] Please refer to the above embodiments for further details. Figure 4 and Figure 5 An exposure hole 7 is provided in the middle of both the base plate 601 and the cover plate 602. By setting the exposure hole 7, external light can pass through the shutter system, control the shutter system to work, and thus achieve the purpose of controlling the exposure.
[0045] Please refer to the above embodiments for further details. Figure 1 A through hole matching the exposure hole 7 is opened on the top of the carrier plate 1, so that external light can enter the equipment by setting the through hole on the carrier plate 1.
[0046] Please refer to the above embodiments for further details. Figure 1The shutter assembly 6 is provided in multiple groups, and the multiple groups of shutter assemblies 6 are distributed sequentially from top to bottom. The arrangement of multiple groups of shutter assemblies 6 in sequence from top to bottom ensures that the curtains 604 of the multiple groups of shutter assemblies 6 will not collide with each other.
[0047] Please refer to the above embodiments for further details. Figure 1 Multiple shutter assemblies 6 are evenly distributed around the exposure hole 7. By setting multiple shutter assemblies 6 to be evenly distributed around the exposure hole 7, the curtains 604 of the multiple shutter assemblies 6 can move closer to each other to adjust the size of the exposure hole 7.
[0048] In practical operation, when the shutter system is in use, the user presses the shutter button, and the device controls the drive device of the transmission gear 5 through an electrical signal. The transmission gear 5 rotates, driving the movable ring 2 to rotate. The movable ring 2 drives multiple sets of first gear groups 603 and second gear groups 608 to rotate through the internal gear ring 4. When the multiple sets of first gear groups 603 rotate synchronously, they drive the curtains 604 of each shutter assembly 6 to move closer to each other, thereby blocking the exposure hole 7. Since each set of curtains 604 is not at the same horizontal height, the multiple sets of curtains 604 will not collide when they move closer to each other. Reducing the mutual collision of multiple sets of curtains 604 can reduce the wear of mechanical parts, reduce noise, and extend the service life of the shutter system.
[0049] When the drive device connected to the transmission gear 5 is working, it is equipped with a light sensor to monitor its operating speed, such as a BPW34 photodiode or a GL5516 CMOS image sensor, so that the shutter system can automatically adjust the closing speed of the shutter system according to the light intensity.
