Description

Technical Field

[0001] This utility model relates to the field of imaging equipment technology, and in particular to an ICR switching module for a camera device. Background Technology

[0002] An ICR switcher is an infrared camera accessory used to switch filters between infrared-insensitive and infrared-sensitive filters during the day and at night. Its main function is to switch between IR and AR filters via an electromagnetic drive to meet imaging requirements under different lighting conditions. In existing technology, most traditional ICR switchers use a single-layer structure, switching between IR and AR glasses separately via electromagnetic drive. However, with the increasing precision and miniaturization of optical camera systems, the design of traditional ICR switchers has gradually revealed the following shortcomings: First, the single-layer structure not only increases the size of the device but also limits the compact development of the camera module to some extent. Second, traditional ICR switchers often experience problems such as light leakage through the center aperture during switching, affecting imaging quality and making it difficult to meet the requirements of high-precision imaging.

[0003] Furthermore, traditional ICR switchers often lack sufficient holding force, especially under conditions of high impact, high vibration, or prolonged use. This can easily lead to instability in the glass plate's position, thus affecting the overall performance of the imaging system. On the other hand, in traditional ICR switcher designs, the magnetic valve and glass plate structure are typically located in the same space. This means that during crank-driven switching, the glass plate is highly susceptible to vibration or impact, causing dust to fall into the structure and contaminate the glass plate. This dust not only affects image clarity but can also damage optical components, shortening the product's lifespan.

[0004] Therefore, although existing ICR switchers can meet basic requirements to a certain extent, they still have significant shortcomings in terms of accuracy, stability, shock resistance, and cleanliness, and urgently need to be innovated and improved. Utility Model Content

The magnetic valve drive area includes a U-shaped iron core, a drive coil, and a magnetic ring, all enclosed and separated by a magnetic valve base. The optical switching area only contains the filter assembly and the light-passing hole. Through physical isolation, the filter is prevented from being affected by vibrations or dust generated during magnetic valve drive during switching, effectively improving the cleanliness and imaging stability of the filter and optical path, and reducing the risk of contamination.

[0022] 3. The switching base of this utility model adopts an inverted T-shaped one-piece molding structure, with the width of the first end being greater than that of the second end.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0038] In the description of this utility model, unless otherwise stated, all components used are conventional components in the prior art.

[0039] like Figure 1-10As shown, this utility model provides an ICR switching module for a camera device, including a switching base 1 and a fixed cover 2 that covers one side of the switching base 1; a first switching component 3 and a second switching component 4 are movably disposed between the switching base 1 and the fixed cover 2; the ICR switching module of this application can be applied to camera devices including but not limited to drones, security monitoring equipment, vehicle monitoring systems, smart home indoor and outdoor monitoring systems, industrial inspection camera equipment, medical imaging equipment, environmental monitoring camera equipment, etc., to automatically switch filters to optimize image quality.

[0040] For example, the ICR switching module of this application is applied to UAV camera devices to meet the flight impact and vibration conditions of UAVs under conditions such as flight, rapid take-off and landing, dive and emergency stop. With high holding force, it ensures the accuracy of filter switching action and optical path switching precision, avoids problems such as switching inaccuracy caused by environmental stress, improves the stability and imaging consistency of UAV optical system in complex flight environment, and significantly enhances the reliability and service life of the whole machine.

[0041] Overall, this invention significantly enhances the stability, reliability, and lifespan of the UAV optical system in complex flight environments, ensuring smooth image switching without offset and guaranteeing high-precision imaging.

[0042] Specifically, the first switching component 3 includes a first switching plate 31 and a first filter 32; the second switching component 4 includes a second switching plate 41 and a second filter 42; the first filter 32 and the second filter 42 are respectively embedded in the light-transmitting holes of the first switching plate 31 and the second switching plate 41; the first switching plate 31 and the second switching plate 41 are respectively movably disposed on the switching base 1, and the first filter 32 and the second filter 42 are respectively staggered and stacked vertically along their moving direction; in this embodiment, the first filter 32 is an IR filter and the second filter 42 is an AR filter; the first filter 32 and the second filter 42 are respectively embedded in the light-transmitting holes of the first switching plate 31 and the second switching plate 41, and are staggered and stacked vertically along the switching direction, so that the two filters will not interfere or block each other during the switching process, and the synchronous movement of the two filters can be realized in a limited space, improving the space utilization and structural compactness of the module.

[0043] The switching base 1 is equipped with a driving assembly 5, which includes a driving crank 51 rotatably mounted on the switching base 1. The two ends of the driving crank 51 are respectively connected to the first switching plate 31 and the second switching plate 41, and drive the first switching plate 31 and the second switching plate 41 to move synchronously in opposite directions to achieve the switching between the first filter 32 and the second filter 42. In this embodiment, the driving assembly adopts a single driving crank design, with both ends moving in opposite arc directions to drive the corresponding switching plates to move synchronously in opposite directions. The switching process is coordinated and consistent, smooth, and responsive, resulting in higher filter position control precision. Simultaneously, it reduces the number of driving electromagnetic components, lowering structural complexity and energy consumption.

[0044] In this embodiment, to avoid friction between the drive handle and other components, anti-collision rubber rings 9 are respectively provided on both ends of the rotation stroke of the drive handle 51 on the switching seat 1.

[0045] Specifically, the drive crank 51 is rotatably disposed on the side of the switching seat 1 away from the fixed cover 2, with a first protrusion 511 and a second protrusion 512 at its two ends respectively; the switching seat 1 is provided with a first arc-shaped hole 11 and a second arc-shaped hole 12 respectively along the rotation path of the first protrusion 511 and the second protrusion 512; one end of the first switching plate 31 and the second switching plate 41 is provided with a first strip hole 311 and a second strip hole 411 respectively adapted to the first protrusion 511 and the second protrusion 512; the first protrusion 511 and the second protrusion 512 pass through the first arc-shaped hole 11 and the second arc-shaped hole 12 respectively, and slide in cooperation with the first strip hole 311 and the second strip hole 411 to drive the first switching plate 31 and the second switching plate 41 to move synchronously. In this embodiment, when the drive crank is rotated, the protrusions at both ends move along their respective arc-shaped hole trajectories, and at the same time drive the two switching plates connected to them to move synchronously in a straight reciprocating motion on the surface of the switching seat.

[0046] like Figure 8As shown, more specifically, the drive assembly 5 includes a U-shaped iron core 52 pulverizedly connected to the drive handle 51, a drive coil 53 wound around the U-shaped iron core 52, and a magnetic ring 54 rotatably disposed in the middle of the U-shaped iron core 52; the drive handle 51 is provided with a connecting shaft 513; the magnetic ring 54 is sleeved on the connecting shaft 513 and drives the drive handle 51 to rotate; a magnetic valve seat 8 is also covered on the outside of the drive assembly 5; a shaft 81 is provided on the inner side of the magnetic valve seat 8, the shaft 81 passes through the central hole of the connecting shaft 513 axially and is connected to the switching seat 1; the drive handle 51 rotates around the shaft 81 via the connecting shaft 513 under the drive of the magnetic ring 54. During operation, when the drive coil is energized, the two poles of the U-shaped iron core generate a magnetic field, which acts on the magnetic ring in the middle, causing the magnetic ring to rotate around the shaft under the drive of the magnetic field torque. The magnetic ring is fixedly connected to the drive crank shaft, so the rotation of the magnetic ring synchronously drives the drive crank to rotate around the axis. As the protrusions at both ends of the drive crank swing along the trajectory of the arc-shaped hole, they respectively push the first and second switching plates connected to them to move, thereby realizing the switching action of the filter.

[0047] To improve the assembly stability of the magnetic valve seat, optionally, the inner wall of the magnetic valve seat 8 near the switching seat 1 is provided with a support post 82 and a limiting post 83 for supporting and positioning the U-shaped iron core 52; a limiting groove 521 adapted to the contour of the support post 82 is recessed at the bottom of one side wall of the U-shaped iron core 52, and the support post 82 extends into the limiting groove 521 to achieve vertical positioning; the limiting post 83 abuts laterally against the other side wall of the U-shaped iron core 52 to achieve lateral limiting and fixing. In this embodiment, the bidirectional limiting and positioning structure formed by the support post and the limiting post effectively improves the assembly stability of the magnetic valve seat and the U-shaped iron core, ensuring switching accuracy and reliability during long-term operation.

[0048] Optionally, a partition 6 is provided between the first switching plate 31 and the second switching plate 41; the shape of the partition 6 is adapted to the switching seat 1, and each is provided with an arc-shaped clearance hole 61 corresponding to the first arc-shaped hole 11 and the second arc-shaped hole 12; the switching seat 1 and the partition 6 are respectively provided with light-passing clearance holes corresponding to the first filter 32 and the second filter 42 (not shown in the figure). In this embodiment, the partition effectively separates the movement space of the first switching plate and the second switching plate, avoiding mutual interference between the two plates during the switching process and improving the reliability of the mechanism's operation.

[0049] Optionally, the bottom of the switching seat 1 is provided with an arched limiting strip 13 to prevent the partition 6 from shifting, and the bottom of the partition 6 is provided with an arched limiting groove 62 adapted to the arched limiting strip 13; the partition 6 is supported on the arched limiting strip 13 through the arched limiting groove 62; a plurality of fixing strips 7 extend from the surface of the switching seat 1 opposite to the fixing cover 2, and the plurality of fixing strips 7 abut against the partition 6 from both sides and clamp and limit its position. In this embodiment, the fixing strips clamp and fix the partition from both sides to prevent it from shifting or tilting. This increases the stability of the partition.

[0050] Optionally, the switching seat 1 includes a first end 14 and a second end 15 along the moving direction of the first switching plate 31 and the second switching plate 41, and is integrally formed inverted T-shaped structure; the width of the first end 14 is greater than the width of the second end 15; the first arc-shaped hole 11 and the second arc-shaped hole 12 are respectively mirror-image through the first end 14 with the rotation center of the drive crank 51 as the center; the ends of the first protrusion 511 and the second protrusion 512 are respectively provided with limiting heads with an outer diameter greater than the width of the first arc-shaped hole 11, the second arc-shaped hole 12 and the arc-shaped clearance hole 61. In this embodiment, the partition is stably supported by the bottom arched limiting strip and the fixing strip, while the inverted T-shaped switching seat, arc-shaped hole and limiting head design ensure the smooth and synchronous movement of the switching plate. This not only ensures the accuracy and stability of filter switching, but also provides higher impact resistance and durability.

[0051] To facilitate the assembly and disassembly of this utility model, in this embodiment, optionally, the fixing cover 2 extends toward the switching seat 1 and is provided with a first hook 21, and the switching seat 1 is provided with a first engaging part 16 that engages with the first hook 21; the switching seat 1 extends toward the magnetic valve seat 8 and is provided with a second hook 17, and the magnetic valve seat 8 is provided with a second engaging part 84 that engages with the second hook 17.

[0052] Alternatively, the switching seat 1 is provided with the first hook 21, and the fixing cover 2 is provided with the first snap-fit ​​part 16;

[0053] Alternatively, the magnetic valve seat 8 may be provided with the second hook 17, and the switching seat 1 may be provided with the second engaging portion 84; the second engaging portion 84 may be provided with guide slopes 841 corresponding to the connection direction of the second hook 17; the assembly of the fixed cover 2, the switching seat 1, and the magnetic valve seat 8 may be achieved through the cooperation of the first hook 21 with the first engaging portion 16 and the second hook 17 with the second engaging portion 84. In this embodiment, the first engaging portion and the second engaging portion may be configured as limiting protrusions or limiting recesses, and their guide slopes may be designed on the front side of the limiting protrusion or limiting recess.

[0054] The fixed cover, switching seat, and solenoid valve seat employ an interchangeable snap-fit ​​and limiting structure. Assembly between components is achieved through snap-fit ​​limiting; a reliable fit can be achieved simply by having a snap-fit ​​on one side and a limiting protrusion or recess on the other. This snap-fit ​​quick-release structure allows for flexible combination of the fixed cover, switching seat, and solenoid valve seat, significantly improving component versatility and assembly convenience, facilitating maintenance and replacement, and reducing production costs.

[0055] Optionally, the sidewall of the fixed cover 2 is provided with a plurality of connecting lugs 22 along its circumference, which are connected to the switching seat 1. The sidewall of the switching seat 1 is provided with connecting fasteners 18 that engage with the connecting lugs 22. The fixed cover 2 is fitted onto one side of the switching seat 1 through the engaging engagement of the connecting lugs 22 and the connecting fasteners 18.

The hooks of the fixed cover engage with the engaging parts of the switching seat, and the hooks of the switching seat engage with the engaging parts of the solenoid valve seat. The engaging parts can be limiting protrusions or limiting recesses, and are provided with guide slopes. This structure enables quick assembly and disassembly without tools, while ensuring stable assembly and accurate positioning.

[0056] This invention movably arranges a first switching component and a second switching component between a switching base and a fixed cover, and arranges the first and second filters in a staggered, stacked arrangement along the moving direction. A single drive crank with a double-ended structure drives the first and second switching plates to move synchronously in opposite directions, enabling precise synchronous switching of the two sets of filters during the switching process. This ensures synchronized opening and closing of the IR and AR filters, avoiding delays, jamming, or optical axis misalignment caused by inconsistent driving. The filter position control accuracy is higher, while the number of driving electromagnetic components is reduced, lowering structural complexity and energy consumption. Furthermore, the double-layer layout effectively reduces light leakage from the central aperture due to differences in bonding tolerances, improving image quality and optical axis alignment accuracy.
