[0015] In some embodiments, the mounting body is provided with a correction pivot and an aperture pivot, the correction blade is hinged to the correction pivot, and the aperture blade is hinged to the aperture pivot.

[0016] In some embodiments, the correction mechanism is provided with a first drive assembly, which is used to drive the correction leaf to rotate about the correction axis;

[0018] In some embodiments, the mounting body is provided with a corrective pendulum axis track and an aperture pendulum axis track;

[0019] The first driving assembly includes a first driving magnet, a first driving coil, and a first pendulum shaft. The first pendulum shaft is connected to the correcting blade.

[0026] This application also provides an infrared detection device, including the aforementioned infrared shutter.

[0027] Compared with the above background technology, the infrared shutter provided in this application mainly includes a mounting body, a correction mechanism and an aperture mechanism. The mounting body is provided with a light-transmitting hole; the correction mechanism is provided with a correction blade that can move in the mounting body. After the correction blade moves, it completely blocks the light-transmitting hole or leaves the light-transmitting hole; the aperture mechanism is provided with an aperture blade that can move in the mounting body.

[0028] The main problem with existing infrared detection equipment mentioned in the background is that when directly observing ultra-high temperature targets, the equipment may overheat, leading to performance saturation or damage, which limits its application in extreme high-temperature environments. To address this technical problem, this solution integrates an aperture mechanism to achieve energy attenuation, effectively solving this challenge.

[0029] The aperture mechanism adjusts the size of the light-passing aperture through movable aperture blades, thereby controlling the amount of infrared radiation energy passing through. When measuring ultra-high temperature targets, the aperture blades can partially block the light-passing aperture, reducing the amount of infrared radiation reaching the infrared detector. This prevents the equipment from experiencing performance degradation or damage due to overheating. This design allows infrared detection equipment to reduce the amount of infrared radiation received by adjusting the position of the aperture blades when directly observing ultra-high temperature targets, thus protecting the equipment from high-temperature damage.

[0030] The correction mechanism provides image correction based on the obstruction surface, ensuring that the infrared detection device can provide accurate image information under different operating conditions. This correction function is crucial for maintaining image quality and improving detection accuracy.

[0031] Based on the above structural and process descriptions, it can be seen that the infrared shutter has at least the following beneficial effects: by integrating correction and aperture mechanisms, the infrared shutter effectively solves the problem of existing infrared detection equipment being prone to saturation or damage when directly viewing ultra-high temperature targets, thus expanding its application capabilities in extreme high temperature environments.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of an infrared shutter provided in an embodiment of this application. Figure 2 The image shows the back view of the infrared shutter when the aperture blades are closed, as provided in the embodiments of this application.

[0048] In a first specific embodiment, the infrared shutter provided in this application mainly includes an installation body 1, a correction mechanism 2, and an aperture mechanism 3.

[0049] The mounting body 1 is provided with a light-transmitting hole 101; the correction mechanism 2 is provided with a correction blade 21 that can move within the mounting body 1, and the correction blade 21 completely blocks the light-transmitting hole 101 or leaves the light-transmitting hole 101 after it moves; the aperture mechanism 3 is provided with an aperture blade 31 that can move within the mounting body 1, and the aperture blade 31 partially blocks the light-transmitting hole 101 or leaves the light-transmitting hole 101 after it moves.

[0050] like Figure 1 As shown, at this time, both the correction mechanism 2 and the aperture mechanism 3 are in an inactive state. Neither the correction blade 21 nor the aperture blade 31 obstructs the light-transmitting hole 101 to any extent, so the light-transmitting hole 101 is fully exposed, and the amount of light entering is maximized; as Figure 2 As shown, the aperture mechanism 3 is in the activated state at this time. The aperture blade 31 partially blocks the light-transmitting hole 101, which is equivalent to reducing the actual exposed size of the light-transmitting hole 101 and reducing the amount of light entering.

[0051] The main problem with existing infrared detection equipment mentioned in the background is that when directly observing ultra-high temperature targets, the equipment may overheat, leading to performance saturation or damage, which limits its application in extreme high-temperature environments. To address this technical problem, this solution integrates an aperture mechanism 3 to achieve energy attenuation, effectively solving this challenge.

[0052] The aperture mechanism 3 adjusts the size of the light-transmitting aperture 101 via movable aperture blades 31, thereby controlling the amount of infrared radiation energy transmitted. When measuring ultra-high temperature targets, the aperture blades 31 can partially block the light-transmitting aperture 101, reducing the amount of infrared radiation reaching the infrared detector. This prevents the equipment from experiencing performance degradation or damage due to overheating. This design allows the infrared detection equipment to reduce the amount of infrared radiation received by adjusting the position of the aperture blades 31 when directly observing ultra-high temperature targets, thus protecting the equipment from high-temperature damage.

[0053] The correction mechanism 2 provides an image correction function based on the obstruction surface, ensuring that the infrared detection device can provide accurate image information under different operating conditions. This correction function is crucial for maintaining image quality and improving detection accuracy.

[0054] Based on the above structural and process descriptions, it can be seen that the infrared shutter has at least the following beneficial effects: by integrating correction and aperture mechanisms, the infrared shutter effectively solves the problem of existing infrared detection equipment being prone to saturation or damage when directly viewing ultra-high temperature targets, thus expanding its application capabilities in extreme high temperature environments.

[0055] It should be noted that the infrared shutter design described in this embodiment does not strictly limit the specific movement methods of the correction mechanism 2 and the aperture mechanism 3, nor the number of correction blades 21 and aperture blades 31. This means that although this embodiment may demonstrate a specific movement mechanism or blade configuration, in reality, the design can flexibly adapt to many different implementation methods. For example, the movement control of the correction mechanism 2 and the aperture mechanism 3 can be electrically controlled, but is not limited to this; it can also be achieved through other types of control mechanisms, such as pneumatic, hydraulic, or mechanical transmission. Furthermore, the configuration of the correction blades 21 and the aperture blades 31 can be a single blade or multiple blades to adapt to different application needs and performance requirements. Whether it is the rotation, movement, or any other form of movement of the blades, and whether it is a single-blade or multi-blade design, all are within the scope of this embodiment. This flexibility allows designers to select the most suitable movement method and blade configuration according to specific application scenarios and performance goals to achieve the best light control effect.

[0056] Please refer to Figure 3 and Figure 4 ,in, Figure 3 This is an exploded view of the infrared shutter provided in an embodiment of this application. Figure 4 This is a schematic diagram of the assembly and integration mounting base provided in the embodiments of this application.

[0057] In some embodiments, the aperture blade 31 includes a first aperture blade 311 and a second aperture blade 312, which can move closer to or further away from the mounting body 1.

[0058] In this embodiment, the aperture blade 31 is designed to consist of two independently movable blades, namely the first aperture blade 311 and the second aperture blade 312. These two aperture blades can move relative to each other within the mounting body 1, including moving closer and further apart. The main purpose of this design is to improve movement efficiency, enabling the aperture blade 31 to adjust the degree of obstruction of the light-transmitting aperture 101 more quickly, thereby more effectively controlling the amount of light entering the infrared detection device.

[0059] By moving the first aperture blade 311 and the second aperture blade 312 closer together, the open area of ​​the light-transmitting aperture 101 can be rapidly reduced, achieving rapid attenuation of light. This is very useful in situations where it is necessary to reduce light intensity instantly to protect the detector from damage. Conversely, when the two aperture blades move away from each other, the open area of ​​the light-transmitting aperture 101 increases, allowing more light to enter. This rapid adjustment capability enables the infrared detection equipment to adapt to different lighting conditions and environments.

[0060] This dual-aperture design not only improves the flexibility of light control but also enhances the system's response speed, enabling the infrared shutter to adapt more efficiently to environmental changes, especially in applications requiring rapid adjustment of light intensity to protect equipment or optimize image quality. Through this efficient motion mechanism, the aperture mechanism 3 achieves precise control of the light-transmitting aperture 101, ensuring stable operation of the infrared detection equipment under various conditions.

[0061] It should be noted that this embodiment does not limit the movement of the first aperture blade 311 and the second aperture blade 312. Whether it is the rotation, movement or any other form of movement of the blades, it is within the scope of this embodiment.

[0062] In some embodiments, the corrective blade 21 includes a first corrective blade 211 and a second corrective blade 212, which may move closer to or further away from the mounting body 1.

[0063] The principle and explanation of the correction blade 21 are similar to those of the aperture blade 31, and will not be repeated here. The core difference between the two blades is that the first aperture blade 311 and the second aperture blade 312 are combined into a shape to reduce the light-transmitting aperture 101 and achieve the energy attenuation function; the first correction blade 211 and the second correction blade 212 are combined into a shape to close the light-transmitting aperture 101 and achieve the image correction function based on the occlusion surface.

[0064] In some embodiments, the corrective blade 21 and the aperture blade 31 are stacked in the axial direction of the light-transmitting aperture 101; and / or, there are multiple corrective blades 21, which are stacked in the axial direction of the light-transmitting aperture 101; and / or, there are multiple aperture blades 31, which are stacked in the axial direction of the light-transmitting aperture 101.

[0065] In this embodiment, space utilization is optimized by stacking the correction blade 21 and the aperture blade 31 along the axial direction of the light-transmitting aperture 101. Specifically, the correction blade 21 and the aperture blade 31 are not limited to a single piece, but can be multiple blades stacked along the axial direction of the light-transmitting aperture 101. This design avoids the drawback of occupying too much space when a single blade is set alone, because if single blades are arranged side by side, it will significantly increase the size of the device.

[0066] By stacking multiple correction blades 21 axially, more correction function options can be provided without increasing additional space, thereby enhancing the control over light passing through the aperture 101. Similarly, the stacked arrangement of multiple aperture blades 31 allows for finer adjustment of the amount of light entering to adapt to different detection needs. This stacking scheme is applicable not only to the mixed stacking of correction blades and aperture blades, but also to the stacking of multiple blades of a single type, or the stacking of all blades.

[0067] This design allows infrared shutters to maintain full functionality while boasting a smaller overall size. This is particularly important for applications requiring compact design, such as portable devices or space-constrained industrial applications. Reducing the size not only helps decrease the weight and volume of the device but can also lower manufacturing costs, improving its economic viability and market competitiveness. Therefore, this stacking arrangement not only enhances space utilization efficiency but also provides significant advantages for the design and application of infrared shutters.

[0068] In some embodiments, the correction mechanism 2 and the aperture mechanism 3 are spaced apart in the circumferential direction of the light-transmitting aperture 101.

[0069] In this embodiment, the correction mechanism 2 and the aperture mechanism 3 are spaced apart in the circumferential direction of the light-transmitting hole 101. This design not only optimizes space utilization but also ensures that the two mechanisms do not interfere with each other during operation, thereby improving the stability and reliability of the overall system.

[0070] Furthermore, the correction mechanism 2 and the aperture mechanism 3 can be positioned on different sides of the light-transmitting aperture 101, i.e., each can be positioned on a single side. This configuration ensures that each mechanism has sufficient space for movement and operation, avoiding performance degradation or malfunction risks caused by space congestion. This separate arrangement allows for more efficient use of available space, ensuring that each mechanism achieves optimal performance when performing its function.

[0071] In some embodiments, the mounting body 1 is provided with a correction shaft 102 and an aperture shaft 103, the correction blade 21 is hinged to the correction shaft 102, and the aperture blade 31 is hinged to the aperture shaft 103.

[0072] In this embodiment, the correction blade 21 is hinged to the correction shaft 102, while the aperture blade 31 is hinged to the aperture shaft 103. This design clarifies the movement of the blades, namely, the blocking or opening of the light-transmitting hole 101 is achieved by rotating around the shaft.

[0073] In embodiments with multiple blades, to accommodate multiple correction blades 21 and aperture blades 31, multiple correction shafts 102 and aperture shafts 103 are also correspondingly configured to ensure that each blade can rotate independently around its own shaft. This design not only allows for precise control of each blade but also allows the system to be finely adjusted as needed to achieve different degrees of light occlusion and image correction.

[0074] In some embodiments, the correction mechanism 2 is provided with a first drive component 22, which is used to drive the correction blade 21 to rotate around the correction shaft 102.

[0075] The aperture mechanism 3 is provided with a second drive component 32, which is used to drive the aperture blades 31 to rotate around the aperture shaft 103.

[0076] In this embodiment, the correction mechanism 2 and the aperture mechanism 3 are each equipped with independent drive components, namely a first drive component 22 and a second drive component 32. The first drive component 22 is specifically used to drive the correction blade 21 to rotate around the correction shaft 102, while the second drive component 32 is used to drive the aperture blade 31 to rotate around the aperture shaft 103. This design ensures that the drive mechanisms of the two mechanisms are completely independent and do not affect each other.

[0077] Due to the independence of the first drive component 22 and the second drive component 32, the operation of one component will not affect the working state of the other. This independence provides greater operational flexibility and system stability. For example, when the correction blade 21 needs to be adjusted individually to optimize image correction, the position of the aperture blade 31 will not be interfered with, and vice versa. This design allows the system to precisely and independently control the correction and aperture functions according to specific application requirements.

[0078] It should be noted that this embodiment does not limit the implementation of the first drive component 22 and the second drive component 32. For example, the motion control of the first drive component 22 and the second drive component 32 can be electrically controlled, but is not limited to this. It can also be through other types of control mechanisms, such as pneumatic, hydraulic or mechanical transmission.

[0079] In some embodiments, the mounting body 1 is provided with a corrective pendulum axis track 104 and an aperture pendulum axis track 105;

[0080] The first drive assembly 22 is provided with a first drive magnet 221, a first drive coil 222 and a first pendulum shaft 223. The first pendulum shaft 223 is connected to the correction blade 21. The first drive coil 222 is used to drive the first pendulum shaft 223 to move along the correction pendulum shaft track 104 by magnetic force when powered on.

[0081] The second drive assembly 32 is provided with a second drive magnet 321, a second drive coil 322 and a second pendulum shaft 323. The second pendulum shaft 323 is connected to the aperture blade 31. The second drive coil 322 is used to drive the second pendulum shaft 323 to move along the aperture pendulum shaft track 105 by magnetic force when powered on.

[0082] In this embodiment, the mounting body 1 is equipped with a dedicated correction pendulum axis track 104 and an aperture pendulum axis track 105, which are used to guide the movement of the first pendulum axis 223 and the second pendulum axis 323. The first drive assembly 22 consists of a first drive magnet 221, a first drive coil 222, and a first pendulum axis 223, wherein the first pendulum axis 223 is connected to the correction blade 21. When the first drive coil 222 is energized, the generated magnetic force will drive the first pendulum axis 223 to move along the correction pendulum axis track 104, thereby driving the correction blade 21 to rotate around the correction axis 102, achieving complete blocking or removal of the light-transmitting hole 101.

[0083] Similarly, the second driving assembly 32 consists of a second driving magnet 321, a second driving coil 322, and a second pendulum shaft 323, with the second pendulum shaft 323 connected to the aperture blades 31. When the second driving coil 322 is energized, the generated magnetic force drives the second pendulum shaft 323 to move along the aperture pendulum shaft track 105, driving the aperture blades 31 to rotate around the aperture shaft 103, thereby partially blocking or removing the light-transmitting hole 101.

[0084] This design ensures that when powered on, the first pivot 223 can close the correction blade 21, completely blocking the light-transmitting aperture 101, while the second pivot 323 can close the aperture blade 31, partially blocking the light-transmitting aperture 101. When powered on in reverse, i.e., the current direction is changed, the first pivot 223 and the second pivot 323 will drive the correction blade 21 and the aperture blade 31 to move in opposite directions, thereby opening the blades and fully exposing the light-transmitting aperture 101, allowing light to pass through freely.

[0085] It should be noted that there are several ways to drive the pendulum using magnetic force, as explained below.

[0086] In the first case, the driving magnet is set in a U-shape, and the driving coil is wound around the driving magnet. When the driving coil is energized, the driving coil and the driving magnet generate a magnetic force. The pendulum shaft is magnetic, and the generated magnetic force is used to control the movement of the pendulum shaft. The range of movement of the pendulum shaft is limited by the pendulum shaft track.

[0087] In the second case, the driving coil generates magnetic force when energized, and the driving magnet also has magnetic force. The driving magnet and the driving coil generate relative motion. Therefore, either the driving magnet or the driving coil can move. Regardless of which moves, as long as a force is applied to the pendulum axis, the pendulum axis can move. In this case, the pendulum axis does not need to be magnetic.

[0088] In some embodiments, the mounting body 1 is provided with conductive contacts 106. The portion of the conductive contacts 106 located inside the mounting body 1 is electrically connected to the first drive coil 222 and the second drive coil 322, while the portion of the conductive contacts 106 located outside the mounting body 1 is used to connect to the control circuit.

[0089] In this embodiment, the mounting body 1 is provided with conductive contacts 106. These contacts are internally connected to the first drive coil 222 and the second drive coil 322, and are responsible for transmitting electrical energy. The external part is used to connect to the external control circuit. This design allows the control circuit to easily control the drive coils, thereby precisely controlling the movement of the correction blade 21 and the aperture blade 31, and realizing the control of the light-transmitting hole 101.

[0090] As an optional implementation, different conductive contacts 106 can be provided for the first drive coil 222 and the second drive coil 322 respectively. This design allows the external control circuit to control each drive coil independently. In this way, the behavior of the first drive coil 222 and the second drive coil 322 can be precisely adjusted to achieve precise control of the correction blade 21 and the aperture blade 31. This independent control capability enables the system to respond more flexibly to different operational requirements, improving the overall performance and adaptability of the infrared shutter system.

[0091] In some embodiments, the installation body 1 includes:

[0092] Casing 11;

[0093] The assembly and integration mounting base 12 is provided with a correction mechanism 2 and an aperture mechanism 3, and the assembly and integration mounting base 12 is located in the outer shell 11;

[0094] The upper cover plate 13 and the lower partition plate 14 are stacked on the assembly and integration mounting base 12, and the correction blade 21 and the aperture blade 31 are located between the upper cover plate 13 and the lower partition plate 14.

[0095] In this embodiment, the structural design of the mounting body 1 includes several key components to ensure the effective integration and operation of the correction mechanism 2 and the aperture mechanism 3. Specifically, the mounting body 1 consists of a housing 11, an integrated mounting base 12, an upper cover plate 13, and a lower partition plate 14.

[0096] The outer casing 11 is the external protective structure of the mounting body 1, providing physical protection and fixation for the internal components. The assembly and integration mounting base 12 is the mounting platform for the correction mechanism 2 and the aperture mechanism 3. It is designed to accommodate all components of these two mechanisms and is housed inside the outer casing 11. This design makes the entire system compact and easy to integrate.

[0097] The upper cover plate 13 and the lower partition plate 14 are two main structural components inside the mounting body 1, which are stacked on the assembly and integrated mounting base 12. The upper cover plate 13 is located at the top, while the lower partition plate 14 is located at or near the bottom. The corrective blade 21 and the aperture blade 31 are disposed between the upper cover plate 13 and the lower partition plate 14, and this space provides the necessary range of motion for the blade movement.

[0098] This structural design not only ensures that the corrective blades 21 and the aperture blades 31 can move freely on their tracks, but also protects these precision components from external interference. Simultaneously, by integrating these components into a sealed space, the impact of dust and other contaminants is reduced, thereby improving the system's reliability and durability. Furthermore, this design facilitates assembly and maintenance, as all critical components are centrally located for easy access and inspection.

[0099] Specifically, the corrective blade 21 and the aperture blade 31 are located on one side of the assembly and integration mounting base 12, while the first drive assembly 22 and the second drive assembly 32 are located on the other side of the assembly and integration mounting base 12. This is equivalent to setting the blade part and the drive part on both sides respectively with the assembly and integration mounting base 12 as the reference, thus optimizing the spatial layout.

[0100] In some cases, the light-transmitting hole 101, the corrective pendulum axis track 104, and the aperture pendulum axis track 105 on the mounting body 1 are composed of various components of the mounting body 1.

[0101] Specifically, the upper cover plate 13 is provided with a first light-transmitting window 131 to form a light-transmitting hole 101; correspondingly, the outer shell 11, the assembly and integration mounting base 12 and the lower partition plate 14 are also provided with corresponding light-transmitting windows, such as the second light-transmitting window 127 on the assembly and integration mounting base 12.

[0102] The assembly and integration mounting base 12 is provided with a first correction track 121 for forming a correction swing shaft track 104, and the assembly and integration mounting base 12 is provided with a first aperture track 122 for forming an aperture swing shaft track 105; correspondingly, the upper cover plate 13 and the lower partition plate 14 are also provided with corresponding correction tracks and aperture tracks.

[0103] In some cases, the conductive contact 106 is located on the housing 11.

[0104] In some cases, the correction shaft 102 and the aperture shaft 103 are mounted on the assembly mounting base 12. In particular, when the correction blade 21 includes a first correction blade 211 and a second correction blade 212, the correction shaft 102 includes a first correction shaft 123 and a second correction shaft 124, the first correction blade 211 is hinged to the first correction shaft 123, and the second correction blade 212 is hinged to the second correction shaft 124; the aperture blade 31 includes a first aperture blade 311 and a second aperture blade 312, and the aperture shaft 103 includes a second aperture shaft 125 and a first aperture shaft 126, the first aperture blade 311 is hinged to the first aperture shaft 126, and the second aperture blade 312 is hinged to the second aperture shaft 125.

[0105] Please refer to Figures 5 to 8 ,in, Figure 5 This is a schematic diagram showing the infrared shutter with the correction blades and aperture blades open, as provided in an embodiment of this application. Figure 6 This is a schematic diagram of the infrared shutter when the aperture blades are closed, as provided in an embodiment of this application. Figure 7 This is a schematic diagram of the infrared shutter during blade closure correction provided in an embodiment of this application. Figure 8 This is a rear view of the assembly and integration mounting base provided in an embodiment of this application.

[0106] like Figure 5As shown, when the second pivot axis 323 is located on the lower right side of the first aperture track 122 and the first pivot axis 223 is located on the upper left side of the first correction track 121, the first aperture blade 311 and the second aperture blade 312, the first correction blade 211 and the second correction blade 212 are respectively pulled by the pivot axis to be close to the outer shell 11. At this time, the light-transmitting hole 101 is not blocked, and the light path can freely enter and exit.

[0107] like Figure 6 As shown, when the second driving magnet 321 is energized through the conductive contact 106, the second driving magnet 321 and the second driving coil 322 together drive the second pendulum shaft 323 to rotate. At this time, the second pendulum shaft 323 drives the first aperture blade 311 and the second aperture blade 312 to rotate around the second aperture shaft 125 and the first aperture shaft 126, respectively. When the second pendulum shaft 323 moves obliquely upward along the first aperture track 122, the first aperture blade 311 and the second aperture blade 312 overlap and close, and the combined shape partially blocks the light-transmitting hole 101, realizing the energy attenuation function. When the power is reversed again, the second pendulum shaft 323 retracts, and the first aperture blade 311 and the second aperture blade 312 open again. In addition, the combined shape of the first aperture blade 311 and the second aperture blade 312 can be customized according to actual needs.

[0108] like Figure 7 As shown, when the first driving magnet 221 is energized through the conductive contact 106, the first driving magnet 221 and the first driving coil 222 together drive the first pendulum shaft 223 to rotate. At this time, the first pendulum shaft 223 drives the first correction blade 211 and the second correction blade 212 to rotate around the first correction shaft 123 and the second correction shaft 124 respectively. When the first pendulum shaft 223 moves obliquely downward along the first correction track 121, the first correction blade 211 and the second correction blade 212 overlap and close, completely blocking the light-transmitting hole 101. At this time, the image correction function based on the blocking surface can be realized. When the power is reversed again, the first pendulum shaft 223 retracts, and the first correction blade 211 and the second correction blade 212 open again.
