Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1, one embodiment of the present application provides an angle adjustment mechanism.

In this embodiment, the angle adjusting mechanism includes an outer frame 100, an inner ring adjusting member 200, a shift lever 300, a slider 400, and an adjusting lever 500; the outer frame 100 is formed with a sliding groove 110 along a first direction; the inner ring adjuster 200 is movably disposed in the outer frame 100; the first end of the deflector rod 300 is connected with the inner ring adjusting piece 200, the second end of the deflector rod 300 is provided with a protruding part 310, and the width of the protruding part 310 is larger than that of the middle part of the deflector rod 300; the sliding block 400 is arranged in the sliding groove 110, the sliding block 400 is provided with a groove 410, the second end of the deflector rod 300 is arranged in the groove 410, and in the first direction, the protruding part 310 is contacted with two opposite side walls of the groove 410; the adjusting lever 500 is connected with the sliding block 400, and the adjusting lever 500 is used for driving the sliding block 400 to slide along the sliding groove 110 in a first direction, so that the sliding block 400 pushes the second end of the driving lever 300 along the first direction, and the first end of the driving lever 300 drives the inner ring adjusting member 200 to move in the outer frame 100.

In some embodiments, the inner ring adjuster 200 may be a circular member, and an edge of the inner ring adjuster 200 is slidably coupled to the outer frame 100 such that a rotation axis of the inner ring adjuster 200 is parallel to a normal line. The rotation axis may be located at the center of the inner ring adjuster 200, and the inner ring adjuster 200 rotates on the surface of the outer frame 100.

The inner ring adjuster 200 may be used to mount a camera or a light source. The optical path of the camera or the light source is further adjusted by adjusting the rotation angle of the inner ring adjusting member 200. Of course, the inner race adjuster 200 may also be used to mount other devices.

In some embodiments, the inner ring adjuster 200 is disposed on the horizontal plane of the outer frame 100, and the rotation plane of the inner ring adjuster 200 is the horizontal plane. The first direction may be parallel to the rotation plane of the inner race adjuster 200, which may be a straight line direction in a horizontal plane, such as a left-right direction in fig. 1. The inner ring regulating member 200 may perform a rotational movement in a second direction in the outer frame 100, which is a rotational direction in a horizontal plane, and may be clockwise or counterclockwise.

It should be noted that the adjusting lever 500 may be driven by a driving device. The driving device is used for providing power and can be a motor and the like. The adjustment lever 500 has a movement in a left or right direction by the driving of the driving means, thereby pushing the slider 400 to move left or right. Of course, the adjustment lever 500 may also be operated manually.

In some embodiments, the sliding groove 110 is disposed in a left-right direction, and the slider 400 may slide in the left-right direction at the sliding groove 110. The adjustment lever 500 may be disposed in the left-right direction, and one end of the adjustment lever 500 is connected to the slider 400. When receiving a pushing or pulling force in the left-right direction, the adjustment lever 500 moves leftwards or rightwards, thereby pushing the slider 400 to slide. When the sliding block 400 slides, the groove 410 on the sliding block 400 can push the shift lever 300 to swing.

In the present embodiment, the first end of the lever 300 is fixedly coupled to the inner ring adjuster 200, for example, the first end of the lever 300 may be coupled to the inner ring adjuster 200 by a screw. The lever 300 swings left or right by the pushing of the slider 400, thereby driving the inner race adjuster 200 to rotate left or right.

Referring to fig. 2, the width of the boss 310 refers to the width of the boss 310 in a cross section along the horizontal direction, and the middle of the lever 300 refers to a portion between the side of the lever 300 connected to the inner ring adjuster 200 and the boss 310. The width of the boss 310 is greater than the width of the middle of the lever 300 in a horizontal cross section.

In the present embodiment, the left and right sides of the boss 310 are in contact with the groove walls of the left and right sides of the groove 410, i.e., the width of the boss 310 in the left and right direction is equal to the width of the groove 410 in the left and right direction. When the slider 400 slides left and right, the protrusion 310 always contacts with the groove 410, thereby eliminating lost motion during commutation. Meanwhile, since the width of the protrusion 310 is greater than that of the middle of the lever 300, it is ensured that the lever 300 and the groove 410 do not interfere at different angles.

In some embodiments of the present application, the boss 310 may be spherical. The width of the boss 310 is the diameter of itself and does not change as the diameter of the sphere rotates itself. Therefore, when the shift lever 300 and the groove 410 are at different angles, the convex portion 310 can be contacted with the groove walls on the left side and the right side of the groove 410 more stably.

According to the angle adjusting mechanism, the adjusting rod 500 is utilized to push the sliding block 400, so that the sliding block 400 pushes the deflector rod 300, the deflector rod 300 drives the inner ring adjusting piece 200 to rotate, a contact gap is not formed between the sliding block 400 and the deflector rod 300, and idle stroke cannot occur when the sliding block 400 is used for direction switching, so that action precision is improved, and the rotation angle control precision of the inner ring adjusting piece 200 is ensured.

In some embodiments of the present application, the slider 400 is formed with a first coupling hole, and the first end of the adjustment lever 500 is coupled with the first coupling hole through a first screw thread; the adjusting lever 500 drives the slider 400 to slide along the chute 110 in the first direction by its own movement.

In this embodiment, the first end of the adjusting rod 500 is provided with an external thread, an internal thread is formed in the first fitting hole, and the external thread and the internal thread are fitted as the first thread. The pitch of the first thread may be set according to the need, which is not limited in this embodiment.

In this embodiment, the adjustment lever 500 can be rotated by the driving device. The adjustment lever 500 rotates one turn and the slider 400 slides a pitch stroke with respect to the adjustment lever 500. By controlling the displacement amount of the adjustment lever 500 by the pitch, the control accuracy can be further improved.

As an example, the pitch of the first thread may be 1.5mm, and the adjustment lever 500 makes one rotation, and the slider 400 slides 1.5mm with respect to the adjustment lever 500. Wherein, the slider 400 may slide leftwards or rightwards relative to the adjustment lever 500 according to whether the first screw is a positive screw or a reverse screw.

In some embodiments of the present application, the outer frame 100 is formed with a second coupling hole, and the second end of the adjustment lever 500 is coupled to the second coupling hole through a second thread, and pitches of the first thread and the second thread are different.

In this embodiment, the second end of the adjusting rod 500 is provided with an external thread, and the second fitting hole is internally formed with an internal thread, and the external thread and the internal thread are fitted as the second thread. The pitch of the second thread may be set according to the need, which is not limited in this embodiment.

In the present embodiment, the adjustment lever 500 is rotated by the driving device. The adjustment lever 500 is rotated one turn, and the adjustment lever 500 slides a stroke of one pitch with respect to the outer frame 100. By controlling the displacement amount of the adjustment lever 500 by the pitch, the control accuracy can be further improved.

As an example, the pitch of the second screw thread may be 0.75mm, and the adjustment lever 500 is slid with respect to the outer frame 100 by 0.75mm with one rotation of the adjustment lever 500. Wherein, the slider 400 may slide leftwards or rightwards relative to the adjustment lever 500 according to whether the first screw is a positive screw or a reverse screw.

In some embodiments, a first end of the adjustment bar 500 may be fixedly coupled to the slider 400 using threads, and a second end of the adjustment bar 500 is coupled to the outer frame 100 using threads. The adjusting lever 500 is rotated by the driving device. At this time, the adjustment lever 500 is rotated once, and the adjustment lever 500 is displaced in the left-right direction by a distance of the pitch of the second screw thread with respect to the outer frame 100; meanwhile, due to the rotation of the adjustment lever 500, the slider 400 is displaced in the left-right direction by a distance of the pitch of the first screw thread with respect to the adjustment lever 500. The displacement amount of the slider 400 with respect to the outer frame 100 is a superposition of two distances. By adopting two threads, the control accuracy can be improved, and the control amount can be further enlarged or reduced.

In other embodiments, the first end of the adjusting lever 500 may be fixedly connected to the slider 400 without using a screw, and the second end of the adjusting lever 500 may be connected to the outer frame 100 using a screw. The adjusting lever 500 is rotated by the driving device. At this time, the adjustment lever 500 is rotated once, and is displaced in the left-right direction by a distance of one pitch, which is directly fed back to the slider 400, and the slider 400 follows the adjustment lever 500 to be displaced in the left-right direction by a distance of one pitch.

In some embodiments of the present application, the first thread has the same thread direction as the second thread.

In the present embodiment, the first screw thread is used as a positive screw thread when the adjustment lever 500 is rotated clockwise and moved leftward with respect to the outer frame 100. When the first screw is a positive screw, the adjusting lever 500 moves rightward with respect to the outer frame 100 when rotated counterclockwise. When the second screw is a positive screw, the slider 400 moves rightward with respect to the adjustment lever 500 in the case where the adjustment lever 500 rotates clockwise; when the adjustment lever 500 is rotated counterclockwise, the slider 400 moves leftward with respect to the adjustment lever 500. When the second thread is a reverse thread, the direction of movement is reversed.

As an example, the first thread may be a positive thread and the pitch may be 1.5mm, the second thread may be a positive thread and the pitch may be 0.75mm. When the first screw is rotated in the clockwise direction, the slider 400 is moved to the right by 0.75mm with respect to the outer frame 100; when the first screw is rotated counterclockwise, the slider 400 is moved leftward with respect to the outer frame 100 by 0.75mm.

As an example, the first thread may be a positive thread and the pitch may be 1.5mm, the second thread may be a negative thread and the pitch may be 0.75mm. . For example, the first thread may be a positive thread and the pitch may be 1.5mm, the second thread may be a negative thread and the pitch may be 0.75mm. When the first screw is rotated in the clockwise direction, the slider 400 is moved to the left with respect to the outer frame 100 by 2.25mm; when the first screw is rotated counterclockwise, the slider 400 is moved rightward by 2.25mm with respect to the outer frame 100.

In the present embodiment, the rotation direction of the first screw and the rotation direction of the second screw are set to be the same, so that the displacement amount of the slider 400 relative to the outer frame 100 is the pitch difference between the first screw and the second screw, thereby reducing the adjustment accuracy and further enabling the rotation angle control of the inner ring adjuster 200 to be more accurate.

Referring to fig. 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 chute 110 along a first direction; the deflection mechanism 130 is rotatably disposed on the frame 120, the inner ring adjuster 200 is rotatably disposed on the deflection mechanism 130, and a rotation plane of the deflection mechanism 130 is perpendicular to a rotation plane of the inner ring adjuster 200.

In the present embodiment, the deflection mechanism 130 has a plane, and the inner ring adjuster 200 is disposed on the plane of the deflection mechanism 130. The rotation plane of the inner race adjuster 200 is parallel to this plane. The outer frame 100 may be horizontally disposed, and the rotation plane of the deflection mechanism 130 is a vertical plane. When the deflection mechanism 130 is horizontally arranged, the rotation plane of the inner ring adjusting member 200 is also a horizontal plane; when the deflection mechanism 130 is arranged in a non-horizontal manner, the angle between the rotation plane of the inner ring adjusting member 200 and the horizontal plane is equal to the angle between the plane of the deflection mechanism 130 and the horizontal plane.

Note that, the sliding chute 110 is disposed on the frame 120, and thus the sliding direction of the sliding block 400 in the sliding chute 110 is still a horizontal direction. At this time, the protrusion 310 at the second end of the lever 300 and the groove 410 on the slider 400 may have a contact gap in the vertical direction, so as to ensure that the lever 300 forms an included angle with the horizontal plane without interference after the deflection mechanism 130 deflects. Of course, in the case where the width of the boss 310 in the vertical direction is much greater than the width of the middle portion of the lever 300, the boss 310 may be in contact with the groove walls of the upper and lower sides of the groove 410 in the vertical direction.

It will be appreciated that the deflection mechanism 130 and the inner ring adjustment member 200 may provide angular adjustment in multiple directions, thereby providing more operational angles for devices mounted on the inner ring adjustment member 200, making it more suitable for use in a variety of operational scenarios.

In some embodiments of the present application, the deflection mechanism 130 may include a spindle 131, a center turn adjuster 132, and a jackscrew 133; the rotating shaft 131 is disposed on the frame 120; the middle ring adjusting member 132 is rotatably disposed on the rotating shaft 131, the inner ring adjusting member 200 is rotatably disposed on the middle ring adjusting member 132, and a rotation plane of the middle ring adjusting member 132 is perpendicular to a rotation plane of the inner ring adjusting member 200; the jackscrew 133 is disposed on the frame 120, and one end of the jackscrew 133 abuts against the middle ring adjusting member 132, and the jackscrew 133 is used for adjusting the deflection angle of the middle ring adjusting member 132 relative to the horizontal plane.

In some embodiments, the frame 120 is hollowed out in the middle, and the middle ring adjusting member 132 is disposed in a hollowed-out area in the middle of the frame 120. In addition, the middle part of the middle ring adjusting piece 132 is hollowed out, and the inner ring adjusting piece 200 is arranged in the hollowed-out area in the middle part of the middle ring adjusting piece 132 to form a ring-collar structure. The outer wall of the inner ring adjusting member 200 is slidably connected with the inner wall of the middle ring adjusting member 132, and the inner ring adjusting member 200 can rotate in the hollow area in the middle of the middle ring adjusting member 132.

In some embodiments, the shaft 131 may be disposed on opposite side rims of the frame 120, and the jackscrew 133 and the chute 110 are disposed on opposite side rims of the other two sides. The jackscrew 133 is displaced in the vertical direction by rotation, thereby pushing the middle ring adjuster 132 to rotate.

Referring to fig. 4 and 5, in some embodiments of the present application, the angle adjustment mechanism may further include an adapter 600; the adapter 600 is detachably connected to the inner ring adjuster 200, and is formed with an adapter hole for connecting the member 700 to be mounted.

It should be noted that, the to-be-mounted member 700 may be a camera or a light source, such as a 4K camera and an 8K camera. The positions, the number and the sizes of the transfer holes are set according to the corresponding pieces 700 to be mounted, and different pieces 700 to be mounted correspond to different transfer pieces 600. The to-be-installed part 700 is installed on the angle adjusting mechanism through the adaptor 600, and when the to-be-installed part is replaced, the adaptor 600 is only required to be detached from the inner ring adjusting part 200 higher, the inner ring adjusting part 200 is not required to be replaced, and the operation is simple.

In some embodiments of the present application, the adapter 600 is made of an insulating material.

In this embodiment, the inner ring adjuster 200 is made of metal, so that strength requirements can be guaranteed, and the inner ring adjuster 200 is not easy to deform when bearing forces of different dimensions. Therefore, the adaptor 600 is made of an insulating material, so that the to-be-mounted member 700 and the inner ring adjusting member 200 can be electrostatically isolated, and signal interference of the to-be-mounted member 700 is avoided.
