[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0030] like Figure 1-6 As shown, the camera infrared cutting filter quick switching structure provided in this embodiment includes a housing 1, a detachable cover 2 fixedly disposed on one side of the housing 1, and a fixing component 3 disposed on one side of the cover 2, the fixing component 3 being used at least for the fixed connection between the housing 1 and the cover 2; both the housing 1 and the cover 2 are provided with light holes 4, the light holes 4 on the housing 1 and the cover 2 are aligned and have the same diameter; a rotatable filter switching mechanism 5 is disposed inside the housing 1 and the cover 2, the filter switching mechanism 5 being used at least for switching filters with different functions; a drive module 6 is disposed inside the housing 1 and the cover 2 and is connected to the filter switching mechanism 5 for transmission, the drive module 6 being used at least for driving the filter switching mechanism 5 to rotate.
[0031] In this embodiment, a housing 1 is included, and a removable cover 2 is fixedly provided on one side of the housing 1;
[0032] Specifically, screw holes 11 are provided on the side walls of both the housing 1 and the cover 2. The screw holes 11 are used with screws to connect the housing 1 and the cover 2 to the camera.
[0033] In this embodiment, a fixing component 3 is provided on one side of the cover 2. The fixing component 3 is used for at least the fixed connection between the housing 1 and the cover 2.
[0034] Specifically, a threaded connecting sleeve 33 is fixedly installed on one inner wall of the housing 1, and a through hole 31 is provided at the center of the cover 2. A locking bolt 32 is installed inside the through hole 31 and inserted into the threaded connecting sleeve 33. The locking bolt 32 is inserted into the threaded connecting sleeve 33, thereby fixing the threaded connecting sleeve 33 and the locking bolt 32, and achieving a fixed connection between the cover 2 and the housing 1.
[0035] In this embodiment, both the housing 1 and the cover 2 are provided with light holes 4. The light holes 4 on the housing 1 and the cover 2 are aligned and have the same diameter, so that when light passes through the light holes 4 on the housing 1 and the cover 2, the light is processed by filters with different functions inside, which can filter out unwanted light.
[0036] In this embodiment, a rotatable filter switching mechanism 5 is provided inside the housing 1 and the cover 2. The filter switching mechanism 5 is used at least to switch the position of filters with different functions.
[0037] Specifically, the filter switching mechanism 5 includes a turntable 51. The side wall of the turntable 51 is provided with a number of filter mounting holes 52 that are evenly spaced and arranged in a ring. The outer wall of the turntable 51 is provided with a gear ring 53. Both sides of the turntable 51 are provided with a plane bearing 54 to ensure that the turntable 51 can rotate smoothly. The center of the turntable 51 is provided with a through hole 55, and the fixing component 3 is inserted into the through hole 55.
[0038] Specifically, a protective edge 56 is provided inside the filter mounting hole 52, and a filter 57 is provided in the middle of the protective edge 56. A clamp 58 for pressing the filter 57 is provided inside the filter mounting hole 52. The protective edge 56 and the filter 57 form an integral structure. The clamp 58 is used to fix the filter inside the filter mounting hole 52. The clamp 58 is an elastic structure. When removing it, you can pinch the clamp 58 by hand to shrink it.
[0039] In one embodiment of the present invention, two outer rails 12 are provided inside the housing 1;
[0040] On one side of the outer wall of the turntable 51, there are two rings, one 59 and the other 60. The rings 59 and the other 60 are slidably connected to the outer rails 12. When the turntable 51 rotates, the rings 59 and the other 60 slide with the two outer rails 12, which serves to guide the rotation of the turntable 51.
[0041] In this embodiment, a drive module 6 is provided on one side of the inner side of the housing 1 and the cover 2, which is connected to the filter switching mechanism 5. The drive module 6 is at least used to drive the filter switching mechanism 5 to rotate.
[0042] Specifically, the drive module 6 includes a drive motor 61 fixed inside the housing 1. A gear 62 is mounted on the output shaft of the drive motor 61. A controller 63 is provided on one side of the housing 1. The controller 63 is electrically connected to the drive motor 61 and the positioner 7. When the drive motor 61 is started, it can drive the gear 62 to rotate. The gear 62 drives the gear ring 53 to rotate, thereby realizing the replacement of filters 57 at different positions on the turntable 51. Different filters 57 correspond to different wavelengths of light beams. For example, a daytime air gap filter blocks visible light and only allows near-infrared light to pass through, ensuring color reproduction; an infrared-sensitive filter blocks visible light and only allows infrared light to pass through, enhancing the nighttime imaging effect.
[0043] In this embodiment, a locator 7 is provided on one side of the inner side of the housing 1 and the cover 2. The locator 7 is a laser locator. The infrared locator 7 emits infrared rays and receives the returned signals. The locator 7 is installed on one side of the toothed ring 53. When the infrared rays emitted by the locator 7 are blocked by the tooth structure of the toothed ring 53, a count is completed. Since the number of teeth of the toothed ring 53 is fixed, the rotation angle of the turntable 51 can be determined by counting the number of teeth of the toothed ring 53 by the locator 7. The rotation angle data of the turntable 51 can be transmitted to the controller 63, and the controller 63 micro-controls the drive motor 61 to ensure the accuracy and precision of the replacement each time the filter 57 is changed.
[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
