[0032] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0033] Reference Figure 1 , an embodiment of the present application provides an angle adjustment mechanism.

[0034] In this embodiment, the angle adjustment mechanism includes an outer frame 100, an inner ring adjustment member 200, a lever 300, a slider 400 and an adjustment rod 500; the outer frame 100 is formed with a slide groove 110 along a first direction; the inner ring adjustment member 200 is movably arranged in the outer frame 100; the first end of the lever 300 is connected to the inner ring adjustment member 200, and the second end of the lever 300 is formed with a protrusion 310, the width of the protrusion 310 is greater than the width of the middle part of the lever 300; the slider 400 is arranged on the slide In the groove 110, the slider 400 is formed with a groove 410, and the second end of the lever 300 is placed in the groove 410. In the first direction, the protrusion 310 contacts the opposite side walls of the groove 410; the adjusting rod 500 is connected to the slider 400, and the adjusting rod 500 is used to drive the slider 400 to slide along the slide groove 110 in the first direction, so that the slider 400 pushes the second end of the lever 300 along the first direction, and the first end of the lever 300 drives the inner ring adjustment member 200 to move in the outer frame 100.

[0035] In some embodiments, the inner ring adjusting member 200 may be a circular member, with its edge slidably connected to the outer frame 100 such that the rotation axis of the inner ring adjusting member 200 is parallel to the normal. Furthermore, the rotation axis may be located at the center of the inner ring adjusting member 200, and the inner ring adjusting member 200 rotates on the surface of the outer frame 100.

[0036] It should be noted that the inner ring adjustment member 200 can be used to mount devices such as cameras or light sources. By adjusting the rotation angle of the inner ring adjustment member 200, the optical path of the camera or light source can be adjusted. Of course, the inner ring adjustment member 200 can also be used to mount other devices.

[0037] In some embodiments, the inner ring adjusting member 200 is disposed on a horizontal plane of the outer frame 100, and the rotation plane of the inner ring adjusting member 200 is a horizontal plane. The first direction may be parallel to the rotation plane of the inner ring adjusting member 200, and may be a linear direction in the horizontal plane, such as Figure 1 The inner ring adjustment member 200 can rotate in the outer frame 100 along the second direction, which is the rotation direction in the horizontal plane, and can be clockwise or counterclockwise.

[0038] It should be noted that the adjustment rod 500 can be driven by a drive device. The drive device is used to provide power and can be a device such as a motor. Driven by the drive device, the adjustment rod 500 moves leftward or rightward, thereby pushing the slider 400 to move leftward or rightward. Of course, the adjustment rod 500 can also be operated manually.

[0039] In some embodiments, the slide groove 110 is arranged in a left-right direction, and the slider 400 can slide in the left-right direction within the slide groove 110. The adjustment rod 500 can also be arranged in a left-right direction, with one end of the adjustment rod 500 connected to the slider 400. When subjected to a left-right pushing or pulling force, the adjustment rod 500 moves left or right, thereby pushing the slider 400 to slide. As the slider 400 slides, the groove 410 on the slider 400 can push the lever 300 to swing.

[0040] In this embodiment, the first end of the lever 300 is fixedly connected to the inner ring adjusting member 200. For example, the first end of the lever 300 can be connected to the inner ring adjusting member 200 via a thread. Under the push of the slider 400, the lever 300 swings left or right, thereby driving the inner ring adjusting member 200 to rotate left or right.

[0041] Reference Figure 2It should be noted that the width of the raised portion 310 refers to the width of the raised portion 310 in a horizontal cross-section, and the middle portion of the lever 300 refers to the portion between the side where the lever 300 connects to the inner race adjustment member 200 and the raised portion 310. In a horizontal cross-section, the width of the raised portion 310 is greater than the width of the middle portion of the lever 300.

[0042] In this embodiment, the left and right sides of the protrusion 310 contact the left and right walls of the groove 410. That is, the width of the protrusion 310 in the left-right direction is equal to the width of the groove 410 in the left-right direction. As the slider 400 slides left and right, the protrusion 310 always contacts the groove 410, eliminating lost motion during direction changes. Furthermore, because the width of the protrusion 310 is greater than the width of the middle portion of the lever 300, interference between the lever 300 and the groove 410 is prevented at various angles.

[0043] In some embodiments of the present application, the protrusion 310 may be spherical. The width of the protrusion 310 is equal to its diameter, and since the diameter of the sphere does not change when the sphere rotates, this ensures that the protrusion 310 can more stably contact the left and right walls of the groove 410 when the lever 300 and the groove 410 are at different angles.

[0044] According to the angle adjustment mechanism of the present application, the adjustment rod 500 is used to push the slider 400, so that the slider 400 pushes the lever 300, and the lever 300 drives the inner ring adjustment member 200 to rotate. There is no contact gap between the slider 400 and the lever 300. When the slider 400 switches direction, there will be no idle travel, thereby improving the movement accuracy and ensuring the rotation angle control accuracy of the inner ring adjustment member 200.

[0045] In some embodiments of the present application, the slider 400 is formed with a first mating hole, and the first end of the adjusting rod 500 is mated with the first mating hole through a first thread; the adjusting rod 500 uses its own movement to drive the slider 400 to slide along the sliding groove 110 in the first direction.

[0046] In this embodiment, the first end of the adjustment rod 500 is provided with an external thread, and the first matching hole is formed with an internal thread, and the external thread and the internal thread are matched to form a first thread. The pitch of the first thread can be set as required, and this embodiment does not limit this.

[0047] In this embodiment, the adjusting rod 500 can rotate under the drive of the driving device. For each rotation of the adjusting rod 500, the slider 400 slides relative to the adjusting rod 500 by one thread pitch. By controlling the displacement of the adjusting rod 500 using the thread pitch, control accuracy can be further improved.

[0048] As an example, the pitch of the first thread can be 1.5 mm, and when the adjusting rod 500 rotates one circle, the slider 400 slides 1.5 mm relative to the adjusting rod 500. According to whether the first thread is a positive thread or a negative thread, the slider 400 can slide left or right relative to the adjusting rod 500.

[0049] In some embodiments of the present application, the outer frame 100 is formed with a second matching hole, and the second end of the adjustment rod 500 is matched with the second matching hole through a second thread, and the pitches of the first thread and the second thread are different.

[0050] In this embodiment, the second end of the adjustment rod 500 is provided with an external thread, and the second matching hole is formed with an internal thread, and the external thread and the internal thread are matched to form a second thread. The pitch of the second thread can be set as required, and this embodiment does not limit this.

[0051] In this embodiment, the adjusting rod 500 rotates under the drive of the driving device. When the adjusting rod 500 rotates one circle, the adjusting rod 500 slides relative to the outer frame 100 by one pitch. By controlling the displacement of the adjusting rod 500 by the pitch, the control accuracy can be further improved.

[0052] As an example, the pitch of the second thread can be 0.75 mm, and the adjusting rod 500 rotates one circle, and the adjusting rod 500 slides 0.75 mm relative to the outer frame 100. According to whether the first thread is a positive thread or a negative thread, the slider 400 can slide left or right relative to the adjusting rod 500.

[0053] In some embodiments, the first end of the adjustment rod 500 can be fixedly connected to the slider 400 using a thread, and the second end of the adjustment rod 500 can be connected to the outer frame 100 using a thread. The adjustment rod 500 rotates under the drive device. At this time, when the adjustment rod 500 rotates one circle, the adjustment rod 500 is displaced in the left-right direction relative to the outer frame 100 by a distance equal to the pitch of the second thread. At the same time, due to the rotation of the adjustment rod 500, the slider 400 is displaced in the left-right direction relative to the adjustment rod 500 by a distance equal to the pitch of the first thread. The displacement of the slider 400 relative to the outer frame 100 is the sum of the two distances. By using two threads, the control accuracy can be improved and the control amount can be further amplified or reduced.

[0054] In other embodiments, the first end of the adjusting rod 500 may not be fixedly connected to the slider 400 using threads, and the second end of the adjusting rod 500 may be connected to the outer frame 100 using threads. The adjusting rod 500 rotates under the drive device. Each rotation of the adjusting rod 500 results in a horizontal displacement of one thread pitch. This displacement is directly fed back to the slider 400, which then moves horizontally by one thread pitch following the adjustment rod 500.

[0055] In some embodiments of the present application, the hand direction of the first thread and the hand direction of the second thread are the same.

[0056] It should be noted that in this embodiment, the first thread is a positive thread when the adjusting rod 500 rotates clockwise and moves leftward relative to the outer frame 100. Therefore, when the first thread is a positive thread, the adjusting rod 500 moves rightward relative to the outer frame 100 when it rotates counterclockwise. When the second thread is a positive thread, the slider 400 moves rightward relative to the adjusting rod 500 when the adjusting rod 500 rotates clockwise; and moves leftward relative to the adjusting rod 500 when the adjusting rod 500 rotates counterclockwise. When the second thread is a reverse thread, the movement directions are opposite.

[0057] As an example, the first thread is a normal thread with a pitch of 1.5 mm, and the second thread is a normal thread with a pitch of 0.75 mm. When the first thread rotates clockwise, the slider 400 moves 0.75 mm to the right relative to the outer frame 100; when the first thread rotates counterclockwise, the slider 400 moves 0.75 mm to the left relative to the outer frame 100.

[0058] As an example, the first thread is a positive thread with a pitch of 1.5 mm, and the second thread is a negative thread with a pitch of 0.75 mm. For example, the first thread is a positive thread with a pitch of 1.5 mm, and the second thread is a negative thread with a pitch of 0.75 mm. When the first thread rotates clockwise, the slider 400 moves 2.25 mm to the left relative to the outer frame 100; when the first thread rotates counterclockwise, the slider 400 moves 2.25 mm to the right relative to the outer frame 100.

[0059] In this embodiment, by setting the rotation direction of the first thread and the rotation direction of the second thread to be the same, the displacement of the slider 400 relative to the outer frame 100 is equal to the pitch difference between the first thread and the second thread, thereby reducing the adjustment accuracy and making the rotation angle control of the inner ring adjustment member 200 more precise.

[0060] Reference Figure 3 In some embodiments of the present application, the outer frame 100 may include a frame 120 and a deflection mechanism 130; the frame 120 is formed with a slide groove 110 along a first direction; the deflection mechanism 130 is rotatably arranged on the frame 120, and the inner ring adjustment member 200 is rotatably arranged on the deflection mechanism 130, and the rotation plane of the deflection mechanism 130 is perpendicular to the rotation plane of the inner ring adjustment member 200.

[0061] In this embodiment, the deflection mechanism 130 has a flat surface, and the inner ring adjustment member 200 is disposed on this surface of the deflection mechanism 130. The rotation plane of the inner ring adjustment member 200 is parallel to this surface. The outer frame 100 can be positioned horizontally, and the rotation plane of the deflection mechanism 130 is a vertical plane. When the deflection mechanism 130 is positioned horizontally, the rotation plane of the inner ring adjustment member 200 is also horizontal. When the deflection mechanism 130 is not positioned horizontally, the angle between the rotation plane of the inner ring adjustment member 200 and the horizontal is equal to the angle between the plane of the deflection mechanism 130 and the horizontal plane.

[0062] It should be noted that the slide groove 110 is disposed on the frame 120, so the sliding direction of the slider 400 within the slide groove 110 remains horizontal. In this case, a vertical gap can exist between the protrusion 310 at the second end of the lever 300 and the groove 410 on the slider 400. This ensures that even after the deflection mechanism 130 deflects, the lever 300 can still form an angle with the horizontal plane without interfering with the vertical plane. Of course, if the vertical width of the protrusion 310 is significantly greater than the width of the middle portion of the lever 300, the protrusion 310 can also vertically contact the upper and lower walls of the groove 410.

[0063] It is understandable that the deflection mechanism 130 and the inner ring adjustment member 200 can provide angle adjustment in multiple directions, so that the device installed on the inner ring adjustment member 200 has more working angles, making it more suitable for various working scenarios.

[0064] In some embodiments of the present application, the deflection mechanism 130 may include a rotating shaft 131, a middle ring adjusting member 132 and a top screw 133; the rotating shaft 131 is arranged on the frame 120; the middle ring adjusting member 132 is rotatably arranged on the rotating shaft 131, and the inner ring adjusting member 200 is rotatably arranged on the middle ring adjusting member 132, and the rotation plane of the middle ring adjusting member 132 is perpendicular to the rotation plane of the inner ring adjusting member 200; the top screw 133 is arranged on the frame 120, one end of the top screw 133 is in contact with the middle ring adjusting member 132, and the top screw 133 is used to adjust the deflection angle of the middle ring adjusting member 132 relative to the horizontal plane.

[0065] In some embodiments, the frame 120 is hollowed out, and the middle ring adjustment member 132 is disposed in the hollowed-out region in the center of the frame 120. Furthermore, the middle ring adjustment member 132 is also hollowed out, and the inner ring adjustment member 200 is disposed in the hollowed-out region in the center of the middle ring adjustment member 132, forming a ring-within-a-ring structure. The outer wall of the inner ring adjustment member 200 is slidably connected to the inner wall of the middle ring adjustment member 132, allowing the inner ring adjustment member 200 to rotate within the hollowed-out region in the center of the middle ring adjustment member 132.

[0066] In some embodiments, the rotating shaft 131 can be disposed on two opposite sides of the frame 120, and the top screw 133 and the slide groove 110 can be disposed on the other two opposite sides of the frame 120. The top screw 133 can be rotated to achieve vertical displacement, thereby driving the middle ring adjustment member 132 to rotate.

[0067] Reference Figure 4 and Figure 5 In some embodiments of the present application, the angle adjustment mechanism may further include an adapter 600; the adapter 600 and the inner ring adjustment member 200 can be detachably connected, and an adapter hole is formed, which is used to connect the part to be installed 700.

[0068] It should be noted that the mounting component 700 can be a camera or light source, such as a 4K camera or an 8K camera. The position, number, and size of the adapter holes are determined based on the corresponding mounting component 700. Different mounting components 700 correspond to different adapters 600. The mounting component 700 is mounted on the angle adjustment mechanism via the adapter 600. To replace it, simply remove the adapter 600 from the inner ring adjustment member 200 without replacing the inner ring adjustment member 200, making the operation simple.

[0069] In some embodiments of the present application, the adapter 600 is made of insulating material.

[0070] In this embodiment, the inner ring adjusting member 200 is made of metal, which ensures its strength and prevents deformation when subjected to forces of varying dimensions. Therefore, the adapter 600 is made of an insulating material to achieve electrostatic isolation between the component to be mounted 700 and the inner ring adjusting member 200, preventing signal interference with the component to be mounted 700.

[0071] An embodiment of the present application further provides an imaging system, comprising a camera and an angle adjustment mechanism according to the aforementioned embodiment, wherein the camera is mounted on the angle adjustment mechanism. The specific structure of the angle adjustment mechanism can be found in the aforementioned embodiment, and will not be described in detail in this embodiment.

[0072] According to the imaging system of the present application, when the angle adjustment mechanism switches directions, no idle stroke will occur, thereby improving the movement accuracy and ensuring the rotation angle control accuracy of the camera.
