Description

Technical Field

[0001] This utility model belongs to the field of infrared camera technology, specifically relating to a blade anti-detachment linkage shutter structure. Background Technology

[0002] The shutter blades control the amount of light entering the camera by opening and closing, thereby adjusting the exposure time of the image sensor. When the shutter is open, light passes through the lens and shines on the image sensor, making it sensitive to light; when the shutter is closed, the light is blocked, and the image sensor is no longer exposed to light. In this way, by controlling the opening and closing time of the shutter, an image with the desired exposure can be captured. The working principle of infrared camera shutter blades is usually based on the principle of magnetic repulsion and attraction. When the shutter opens and closes, the solenoid valve is energized to generate magnetism, driving the blades to open and close.

[0003] When a traditional shutter closes, the overlap between the blades and the cover plate is small. When the shutter is subjected to impact during closure, the blades may detach from the cover plate, causing the shutter to fail. To prevent the blades from detaching, traditional designs increase the size of the blades by enlarging the overall shape of the shutter, while keeping the aperture unchanged. This results in a larger size, making it impossible to miniaturize the product. Furthermore, the solenoid valve's synchronism is difficult to guarantee in the drive section, causing the shutter's opening and closing actions to be uncoordinated, which affects the imaging quality and working efficiency of the equipment.

[0008] An electromagnetic drive unit is disposed on both sides of the mounting plate;

[0009] A magnetic rocker arm is rotatably mounted at a diagonal position on the mounting plate. The magnetic rocker arm is connected to the blade assembly. An electromagnetic drive component causes the magnetic rocker arm to deflect, which in turn causes the blade assembly to deflect.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1 - Figure 8 As shown, a blade anti-detachment linkage shutter structure includes an orifice-shaped shell 1 and a mounting plate 2 disposed on the orifice-shaped shell 1, and two sets of blade groups 6 are symmetrically disposed on the mounting plate 2;

[0031] It also includes:

[0032] Electromagnetic drive component 3 is disposed on both sides of mounting plate 2;

[0033] The magnetic rocker arm 4 is rotatably set at the diagonal position of the mounting plate 2. The magnetic rocker arm 4 is connected to the blade group 6. The magnetic rocker arm 4 is deflected by the electromagnetic drive component 3, which in turn causes the blade group 6 to deflect.

[0034] Anti-detachment blade 7 is disposed on one side of blade group 6;

[0035] V-shaped synchronous link 5 is arranged between the magnetic rocker arms 4.

[0036] An FPC board 31 is provided between the electromagnetic drive components 3. The electromagnetic drive components 3 are controlled by the FPC board 31. The electromagnetic drive components 3 are fixedly connected to the magnetic rocker arm 4. The magnetic rocker arm 4 is provided with multiple drive rods 41. The V-shaped synchronous link 5 is connected to the magnetic rocker arm 4 through the drive rods 41. The V-shaped synchronous link 5 is provided with a first linkage groove 51 that matches the drive rods 41. When the drive rod 41 at one end of the V-shaped synchronous link 5 deflects, the drive rod 41 on the other magnetic rocker arm 4 is pulled by the V-shaped synchronous link 5 to ensure that the magnetic rocker arms 4 at both ends of the V-shaped synchronous link 5 move synchronously.

[0037] The blade assembly 6 includes multiple blades 61, which are stacked sequentially on the mounting plate 2 to ensure that they do not collide with each other when closed. The blades 61 are rotatably mounted on the mounting plate 2 and have a second linkage groove 62 that matches the drive rod 41.

[0038] The anti-detachment blade 7 is located at the tail end of the blade 61. The anti-detachment blade 7 is L-shaped and has a third linkage groove 71 that cooperates with the drive rod 41. When the blade group 6 is in the closed state, the anti-detachment blade 7 is in the inclined state, thereby pressing against the tail end of the blade 61. When the blade group 6 is in the open state, the anti-detachment blade 7 is in the horizontal state, and the tail end of the anti-detachment blade 7 presses against the tail end of the blade 61. Since the anti-detachment blade 7 is L-shaped, when the anti-detachment blade 7 is horizontal, it will not block the light passage of the orifice shell 1.

[0039] The mounting plate 2 is provided with multiple mounting shafts 21. The blades 61, anti-detachment blades 7 and V-shaped synchronous connecting rods 5 are rotatably mounted on the mounting plate 2 via the mounting shafts 21. The mounting plate 2 is provided with an arc-shaped groove 22. The magnetic rocker arm 4 passes through the mounting plate 2 via the arc-shaped groove 22. The mounting plate 2 is provided with a receiving cavity 23. The V-shaped synchronous connecting rod 5 is disposed in the receiving cavity 23.

[0040] Clamping plates 8 are provided on both sides of the blade assembly 6. The clamping plates 8 are set on the mounting plate 2. The anti-detachment blade 7 is set between the blade assembly 6 and the clamping plates 8. The clamping plates 8 clamp the anti-detachment blade 7 to ensure the stability of the anti-detachment blade 7. The V-shaped synchronous connecting rod 5 is set between the clamping plates 8 and the mounting plate 2 to separate the V-shaped synchronous connecting rod 5 from the anti-detachment blade 7 and prevent the blade assembly 6 from colliding with the V-shaped synchronous connecting rod 5 when it opens and closes.

[0041] It should be noted that the working principle of the blade anti-detachment linkage shutter structure is as follows: First, the entire structure includes an orifice shell 1 and a mounting plate 2 set on it. Two sets of blade groups 6 are symmetrically arranged on the mounting plate 2. The electromagnetic drive unit 3 is set on both sides of the mounting plate 2, and an FPC plate 31 is set between the electromagnetic drive units 3. The electromagnetic drive unit 3 is activated by the FPC plate 31. When the electromagnetic drive unit 3 is working, the magnetic rocker arm 4 will deflect. The magnetic rocker arm 4 is equipped with multiple drive rods 41. The V-shaped synchronous linkage 5, which is rotatably set on the mounting plate 2, is also set between the two magnetic rocker arms 4. Specifically, it is connected by the first linkage groove 51 that matches the drive rods 41. The V-shaped synchronous linkage 5 ensures that the two magnetic rocker arms 4 move synchronously.

[0042] The blade assembly 6 includes multiple blades 61, which are stacked and rotated on the mounting plate 2. Each blade 61 has a second linkage groove 62 that matches the drive rod 41. When the magnetic rocker arm 4 deflects due to the action of the electromagnetic drive 3, it will drive the blades 61 in the blade assembly 6 to deflect through the cooperation of the drive rod 41 and the second linkage groove 62, thereby opening the shutter. At the same time, the anti-detachment blade 7 is located on one side of the blade assembly 6, at the tail end of the blade 61. It has a third linkage groove 71 that cooperates with the drive rod 41. When the drive rod 41 moves, it will also drive the anti-detachment blade 7 to move. During this process, the anti-detachment blade 7 always presses against the tail end of the blade 61, thereby preventing the blade 61 from detaching. Under the drive of the electromagnetic drive 3, the entire structure drives the V-shaped synchronous connecting rod 5 and the blade assembly 6 and the anti-detachment blade 7 to move in coordination through the deflection of the magnetic rocker arm 4, thereby realizing the functions of opening and closing the shutter.

[0043] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
