Alternatively, the limit protrusions 310 may be provided on the sliding plate 300, and the limit grooves 122 may be provided on the side plates 120.

In this scheme, the sliding plate 300 may be fixedly connected to the arc-shaped plates 220 by screws or the like, the sliding plate 300 is in sliding fit with the side plates 120 by the cooperation of the limiting protrusions 310 and the limiting grooves 122, and the two arc-shaped plates 220 abut against two sides of the two side plates 120, so as to realize the rotatable connection between the side plates 120 and the arc-shaped plates 220.

In addition, the cooperation of the limiting protrusion 310 on the sliding plate 300 and the limiting groove 122 on the side plate 120 can also play a role in limiting the rotation range of the arc-shaped plate 220 and the side plate 120, the length of the limiting groove 122 can be changed so as to change the rotation range of the arc-shaped plate 220 and the side plate 120, and further control the angle adjusting range of the lens mounting part 110 and the camera mounting part 210, under the condition, the sliding plate 300 can play a role in rotatably connecting the arc-shaped plate 220 and the side plate 120, and the sliding plate 300 can also play a role in limiting the rotation range of the arc-shaped plate 220 and the side plate 120, so that the sliding plate 300 can play a role in dual purposes.

In the above embodiment, the lens mount 100 and the camera mount 200 are rotatable relative to each other, and during a specific operation, a user can hold the lens mount 100 with one hand and the camera mount 200 with the other hand, and rotate the two hands relative to each other to rotate the lens mount 100 and the camera mount 200 relative to each other. However, it is difficult to precisely control the relative rotation angle between the lens mount 100 and the camera mount 200, and it is difficult to achieve precise adjustment.

For this reason, the tilt-shift mechanism may further include a driving mechanism, such as a motor, the motor is connected to the lens mounting member 100 or the camera mounting member 200, the motor is started, the motor drives the lens mounting member 100 or the camera mounting member 200 connected thereto to rotate, so as to achieve relative rotation of the two, and the rotation angle of the lens mounting member 100 or the camera mounting member 200 connected thereto is controlled by controlling the number of rotation turns of the motor, so as to improve the angle adjustment precision. However, the driving mechanism such as the motor is usually accompanied by vibration and noise during driving, which affects the user experience.

In order to solve the above problems, in the embodiments disclosed in the present application, the shift mechanism may further include a top plate 410, a mounting member 420, and a moving member 430, the top plate 410 may be fixedly connected to the lens mounting member 100, the mounting member 420 may be fixedly connected to the camera mounting member 200, the moving member 430 may be movably provided to the mounting member 420 in a direction of its own axis, and one end of the moving member 430 abuts against the top plate 410, in the case where the moving member 430 moves with respect to the mounting member 420, the moving member 430 applies a force in a moving direction to the top plate 410, the top plate 410 is fixedly coupled to the lens mounting member 100, the whole of the top plate 410 and the lens mounting member 100 cannot move in the moving direction of the moving member 430, but the lens mounting member 100 is rotatably engaged with the camera mounting member 200, and therefore, the top plate 410 and the lens mount 100 can rotate about the rotation axis with respect to the camera mount 200 by the force of the moving member 430. In order to make the rotation of the lens mount 100 and the camera mount 200 smoother, the moving track of the moving member 430 on the top plate 410 may be deviated from the center of the top plate 410, so that the moving member 430 drives the lens mount 100 and the camera mount 200 to relatively rotate more smoothly.

Alternatively, the top plate 410 and the lens mount 100 may be fixedly coupled by a screw coupling or an adhesive coupling. Alternatively, the mount 420 and the camera mount 200 may be fixedly coupled by a screw or an adhesive.

Alternatively, the top plate 410 may be fixedly coupled to the side plate 120 and the mounting member 420 may be fixedly coupled to the arc plate 220, which coupling structure facilitates assembly of the top plate 410 and the mounting member 420.

For the technical scheme of artifical direct rotation lens installed part 100 and camera installed part 200, the relative rotation of lens installed part 100 and camera installed part 200 is realized through the removal of moving member 430 in this application embodiment, through the amount of movement of controlling moving member 430, can accurate control lens installed part 100 and the turned angle of camera installed part 200. For the scheme that uses motor drive lens installed part 100 and camera installed part 200 relative rotation, the relative rotation of the two is controlled through the removal of manual control moving member 430 in this application embodiment, can avoid the vibration and the noise in the angle modulation process, and then promote user's use and experience.

There are various structures for movably mounting the moving member 430 to the mounting member 420, for example, the shaft moving mechanism may include a slide rail and a slider, the slide rail may be connected to the mounting member 420, the slider may be connected to the moving member 430, and the slide rail extends in the same direction as the axial direction of the moving member 430, so that the moving member 430 moves along the axial direction thereof relative to the mounting member 420. Of course, the moving member 430 and the mounting member 420 can be connected by other structures, which is not limited in this application.

In the disclosed embodiment, the moving member 430 may include a first portion 431 and a second portion 432, the first portion 431 and the second portion 432 are connected by a screw structure, an end of the first portion 431 abuts against the top plate 410, and the second portion 432 is connected to the mounting member 420. The first portion 431 is coaxially disposed with the second portion 432. Alternatively, the second portion 432 may be welded to the mounting member 420, or the second portion 432 may be connected to the mounting member 420 by a clamping structure or a screw, so as to facilitate subsequent disassembly and maintenance of the shaft moving mechanism.

By rotating the first part 431, the first part 431 is displaced relative to the second part 432 in the axial direction of the second part 432 during the rotation relative to the second part 432 under the guidance of the screw structure, so that the first part 431 can apply the integral pushing force formed by the top plate 410 and the lens mount 100. In this case, compared to a technical solution of directly pushing the moving member 430 to move in the axial direction, a technical solution of relatively rotating the first part 431 and the second part 432 which are in threaded engagement to realize the movement of the first part 431 in the axial direction can more accurately control the movement amount of the first part 431, and further improve the angle adjustment accuracy of the lens mount 100 and the camera mount 200.

In the embodiment of the present application, the tilt-shift mechanism may further include an elastic member 500, the elastic member 500 is connected between the lens mount 110 and the camera mount 210, and the elastic member 500 is used for driving the moving member 430 to abut against the top plate 410. The number of the elastic members 500 may be one or two, and the number of the elastic members 500 is not limited in the present application. Alternatively, the elastic member 500 may be a tension spring, one end of which is connected to the lens mount 110 by a screw 510, and the other end of which is connected to the camera mount 210 by a screw 510. In the initial state, the elastic member 500 is not elastically deformed, and in the process of relative rotation of the lens mount 100 and the camera mount 200, the elastic member 500 is elastically deformed and accumulates the elastic potential energy required for restoring the deformation, so that the moving member 430 always collides with the top plate 410.

The angle adjustment range of the lens mount 110 and the camera mount 210 is ± 15 ° for example.

Under the condition that the angle between the lens mount 110 and the camera mount 210 is-15 °, the elastic member 500 is not elastically deformed, and in the adjustment process of-15 ° to +15 °, the moving member 430 moves toward the direction close to the top plate 410, and pushes the top plate 410 to make the top plate 410 drive the lens mount 100 to rotate relative to the camera mount 200, in which process the elastic member 500 is deformed, and the deformation amount is gradually increased, because the moving member 430 is always abutted against the top plate 410, under the blockage of the moving member 430, the lens mount 100 and the camera mount 200 cannot rotate in the reverse direction, and the elastic member 500 cannot recover the deformation.

In the adjustment process of +15 ° to-15 °, the moving member 430 moves in a direction away from the top plate 410, so that a gap between the moving member 430 and the top plate 410 tends to be generated, and the lens mounting member 100 and the camera mounting member 200 have a space for reverse rotation, so that the elastic member 500 can gradually recover elastic deformation, and the lens mounting member 100 and the top plate 410 are driven to rotate reversely integrally by the elastic force until the top plate 410 is abutted to the moving member 430 again. In this way, the elastic member 500 is used to restore the elastic force in the deformation process to drive the lens mounting part 110 to rotate relative to the camera mounting part 210, so that the lens mounting part 110 and the camera mounting part 210 can be adjusted from +15 degrees to-15 degrees, and the elastic member 500 can enable the top plate 410 to always abut against the moving member 430, so that the angle between the lens mounting part 110 and the camera mounting part 210 has certain stability.

In this case, the elastic member 500 can make the top plate 410 and the moving member 430 always in a collision state, and when the lens mounting device 100 and the camera mounting device 200 relatively rotate due to an uncontrollable external force, the elastic member 500 can make the lens mounting device 100 and the camera mounting device 200 quickly reset, thereby stabilizing the angle between the lens mounting part 110 and the camera mounting part 210 at an angle required by a user.

Of course, the angular adjustment range of the lens mount 110 and the camera mount 210 may be adjusted according to specific requirements, such as-10 ° to +10 °, -15 ° to +15 °, -20 ° to +20 °, -30 ° to +30 °, and the present application does not limit the angular adjustment range of the lens mount 110 and the camera mount 210.

In a further aspect, the tilt mechanism may further include a locking member 600, and the locking member 600 may lock an angle between the lens mount 100 and the camera mount 200. In the case where the lens mount 100 and the camera mount 200 are in the locked state, the lens mount 100 and the camera mount 200 are relatively fixed, so that the lens mount 110 and the camera mount 210 are also in a relatively fixed state, and thus the lens 1000 and the camera 900 are in a relatively fixed state; in the case where the lens mount 100 and the camera mount 200 are in the unlocked state, the lens mount 100 and the camera mount 200 may be relatively rotated, so that the lens mount 110 and the camera mount 210 are also in the relatively rotatable state, and thus the lens 1000 and the camera 900 are in the relatively rotatable state, and finally the angle between the lens 1000 and the camera 900 is adjustable. In this case, the locking member 600 is used to lock the lens mount 100 and the camera mount 200, so that the relative rotation of the two due to the misoperation can be avoided, and the reliability of the shift mechanism and the photographing device can be improved.

Optionally, the locking member 600 may be a bolt, the bolt passes through the side plate 120 and extends into the limiting groove 122 of the side plate 120, the bolt is screwed, the bolt abuts against the limiting protrusion 310 of the sliding plate 300, so that the side plate 120 and the sliding plate 300 are relatively fixed, the sliding plate 300 is fixedly connected with the arc-shaped plate 220, and further the side plate 120 and the arc-shaped plate 220 are relatively fixed, so that the lens mounting member 100 and the camera mounting member 200 are relatively fixed; the bolt is rotated in the opposite direction to disengage the bolt from the stopper projection 310, so that the side plate 120 and the arc plate 220 can be relatively rotated, and thus the lens mount 100 and the camera mount 200 can be relatively rotated.

When shooting, a part of shooting scene needs to make the lens plane and the image plane parallel, for the convenience of adjustment, one of the lens installation part 100 and the camera installation part 200 may be provided with a center positioning part 710, the other may be provided with a center positioning slot 720, and the center positioning part 710 and the center positioning slot 720 are in positioning fit. The lens mount 110 is disposed in parallel with the camera mount 210 with the centering member 710 in positioning engagement with the centering slot 720.

In the process of angle adjustment, when the center positioning element 710 extends into the center positioning slot 720, the cooperation between the center positioning element 710 and the center positioning slot 720 may generate sound, and may cause a certain resistance to the rotation of the lens mount 110 and the camera mount 210, which indicates that the center positioning element 710 and the center positioning slot 720 are in positioning cooperation, the lens mount 110 and the camera mount 210 are arranged in parallel, and the lens plane and the image plane are arranged in parallel.

Alternatively, the centering member 710 may be disposed on the sliding plate 300, and at least a portion of the centering member 710 extends into the limiting recess 122, and the centering slot 720 may be disposed on the bottom of the limiting recess 122.

In order to more intuitively display the angle between the plane of the lens mount 110 and the plane of the camera mount 210, the axis-shifting mechanism may further include vernier scales, where the vernier scales include a main scale 810 and an auxiliary scale 820, one of the main scale 810 and the auxiliary scale 820 may be fixed with respect to the lens mount 100, the other may be fixed with respect to the camera mount 200, and the relative rotation between the lens mount 100 and the camera mount 200 may drive the main scale 810 and the auxiliary scale 820 to rotate relatively.

In this case, the angle between the plane of the lens mount 110 and the plane of the camera mount 210 can be displayed more intuitively through the vernier scale, and before shooting, the angle to be adjusted can be calculated first, and then the angle adjustment operation between the lens mount 110 and the camera mount 210 is performed, which is more convenient for the precise adjustment of the lens mount 110 and the camera mount 210. In addition, the vernier scale has higher precision compared with the common scale, and the adjustment precision between the camera mounting parts 210 of the lens mounting part 110 can be further improved.

Alternatively, the main scale 810 may be provided on the side plate 120, and the sub scale 820 may be provided on the sliding plate 300, and since the sliding plate 300 is fixedly coupled to the arc plate 220, the sub scale 820 is fixed relative to the camera mounting member 200. Of course, the main scale 810 may be disposed on the sliding plate 300, and the sub-scale 820 may be disposed on the side plate 120, which is not limited in this application.

The tilt mechanism may further include a second mounting hole, and the second mounting hole may be provided to the camera mount 200 to mount the tilt mechanism on the stand of the photographing device through the second mounting hole.

The derivation process of the beneficial effect of the shooting device is substantially similar to the derivation process of the beneficial effect brought by the shaft shifting mechanism, and therefore, the description is omitted here.

In a further embodiment, one of the camera 900 and the camera mounting portion 210 is provided with a first connecting hole group 911, the other is provided with a second connecting hole group 230 and a third connecting hole group 240, and the second connecting hole group 230 and the third connecting hole group 240 are arranged at intervals in the circumferential direction of the camera 900 or the camera mounting portion 210.

The connector may connect the camera 900 and the camera mounting part 210 by being engaged with the first connection hole set 911 and the second connection hole set 230.
