DETAILED DESCRIPTION

[0037] The utility model will be further described in detail below with the specific embodiments combined with the drawings. Similar elements in different embodiments adopt the associated similar element mark. In the following embodiments, many details are described in order to make the present application be better understood. However, the person skilled in the art can easily recognize that part of the features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid the core part of the present application being overwhelmed by too much description, and for the person skilled in the art, it is not necessary to describe these related operations in detail according to the description in the specification and the general technical knowledge in the art.

[0038] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially replaced or adjusted in a manner that is obvious to the person skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0039] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connection (coupling) unless otherwise specified.

[0040] In order to balance the damping feeling and adjustment accuracy during adjustment, the present application provides a damping knob mechanism 200, please refer to Figures 2-4 The damping knob mechanism 200 includes a base 10, a rotating assembly 20 and a damping adjustment assembly 40. The base 10 provides a mounting base for other components. The rotating assembly 20 is rotatably mounted on the base 10, and when performing the parameter adjustment step, the whole rotating assembly 20 is rotated relative to the base 10. The damping adjustment assembly 40 includes a damping member 41 and a driving member 42, the damping member 41 is arranged between the base 10 and the driving member 42, and the driving member 42 is movably connected to the rotating assembly 20. The driving member 42 can rotate relative to the rotating assembly 20 around the rotation axis of the base 10 and the rotating assembly 20, and convert the rotation into movement along the rotation axis to drive the damping member 41 to move along the rotation axis. One of the base 10 and the damping member 41 has a damping groove 11 containing damping grease, and the other has a plug-in segment 411 extending into the damping groove 11 along the rotation axis; the driving member 42 can drive the damping member 41 to move to change the plug-in depth of the plug-in segment 411 and the damping groove 11.

[0041] It can be known through the analysis that, on the one hand, the driving member 42 functions to adjust the position of the damping member 41 along the above-mentioned rotation axis, and further adjust the insertion depth of the insertion section 411 and the damping groove 11, the damping grease is arranged in the damping groove 11, the insertion depth of the insertion section 411 into the damping groove 11 is changed, the filling amount of the damping grease between the insertion section 411 and the damping groove 11 is also changed, and thus the resistance of the damping member 41 relative to the base 10 when rotating can be changed, so as to achieve the effect of damping adjustment through the damping grease in the gap between the insertion section 411 and the damping groove 11. Since the damping member 41 and the rotating assembly 20 are synchronously rotated, when the user operates to make the rotating assembly 20 rotate relative to the base 10, the damping viscous feeling fed back to the user is stronger, the hand feeling is better, the user can adjust the damping hand feeling to the degree required by himself, and thus the adaptability and practicability of the damping knob mechanism 200 and the follow-focus remote controller 1000 are improved.

[0042] On the other hand, when the driving member 42 is rotated, the rotating assembly 20 is manually held, so that the relative rotation between the rotating assembly 20 and the base 10 does not occur, and the rotation of the driving member 42 is converted into displacement movement along the rotation axis of the base 10 and the rotating assembly 20. Under the transmission cooperation of the driving member 42 and the rotating assembly 20, the driving member 42 and the damping member 41 are both moved along the rotation axis relative to the rotating assembly 20, and further the damping effect is improved or weakened. That is to say, in the process of adjusting the insertion depth of the insertion section 411 into the damping groove 11 by rotating the driving member 42, the rotating assembly 20 as a whole does not rotate and move relative to the base 10, the operation of the rotating assembly 20 to realize parameter adjustment and the operation of the damping adjustment assembly 40 to realize damping effect adjustment are relatively independent, which is beneficial to improve the practicability and operability of the damping knob mechanism 200 as a whole, reduce the use difficulty, and facilitate the user operation.

[0043] In summary, the above-mentioned damping knob mechanism 200 includes two steps when in use. When the damping needs to be adjusted, the rotating assembly 20 is fixed, so that the rotating assembly 20 does not rotate relative to the base 10, at this time, the driving member 42 is rotated, so that the driving member 42 and the damping member 41 move towards the base 10 or away from the base 10, and further the insertion depth of the insertion section 411 and the damping groove 11 is changed, so as to correspondingly increase or decrease the damping; when the parameter needs to be adjusted, the rotating assembly 20 is driven to rotate relative to the base 10, the rotating assembly 20 drives the damping member 41 and the driving member 42 to rotate, and parameter adjustment control is realized.

[0044] It needs to be explained that the specific transmission scheme of the utility model for the driving member 42 driving the damping member 41 to move along the rotation axis is not limited, as long as the damping member 41 can change the position with the position change of the driving member 42. For example, in some embodiments, under the driving of the driving member 42, the damping member 4141 can only move along the rotation axis to the direction close to the base 10 or the direction away from the base 10, that is, when the driving member 42 rotates relative to the rotating assembly 20, the damping member 41 will not rotate relative to the rotating assembly 20, but only move along the rotation axis relative to the base 10 and the rotating assembly 20. In some other embodiments, the damping member 41 can also move along the rotation axis while rotating with the driving member 42, at this time, the damping member 41 rotates relative to the base 10, so during the adjustment of the driving member 42, the damping hand feeling can be felt, and then the user can more easily adjust the damping hand feeling to the degree required by himself.

[0045] In some embodiments, please refer to Figure 3 、 Figure 5 and Figure 8 , the damping adjustment assembly 40 further comprises an elastic member 43, the elastic member 43 is installed on the damping groove 11 and abuts the plug-in section 411, along the rotation axis, the elastic member 43 always presses the damping member 41 on the side of the driving member 42 towards the base 10, to match the position of the driving member 42 to adaptively adjust the position of the damping member 41 relative to the base 10, to change the plug-in length of the plug-in section 411 and the damping groove 11 and the size of the rotating damping. In this scheme, the damping member 41 and the driving member 42 can be independent, the driving member 42 rotates and moves along the rotation axis, but the damping member 41 only moves linearly along the rotation axis under the action of the elastic member 43 and the driving member 42.

[0046] In some embodiments, please refer to Figure 3 、 Figure 5 and Figure 8 , the elastic member 43 is a spring, with the movement of the damping member 41 along the rotation axis, the damping member 41 compresses the spring to different degrees, so that the spring will produce different elastic deformation, and because the elastic deformation of the spring follows the law of linear deformation, the damping hand feeling fed back to the user during the rotation of the driving member 42 to change the plug-in depth of the plug-in section 411 and the damping groove 11 will be relatively smooth, and the damping change in this process is also uniform.

[0047] The specific structure of the driving member 42 and the connection scheme of the driving member 42 and the rotating assembly 20 are not limited, as long as the driving member 42 has the function of rotating while moving along the rotating axis of the base 10 and the rotating assembly 20. In addition, the central axis of the driving member 42 relative to the rotating assembly 20 can be coaxial with the rotating axis of the rotating assembly 20 and the base 10, or can be offset from each other, as long as the driving member 42 has a moving component along the rotating axis of the base 10 and the rotating assembly 20.

[0048] In some embodiments, the driving member 42 can be an integral member, and the driving member 42 is threadedly connected with the rotating assembly 20, so that the driving member 42 can move towards or away from the base 10 along the threaded direction while rotating.

Along the rotating axis, the damping member 41 is arranged between the base 10 and the pressing panel 422, and the pressing panel 422 drives the damping member 41 to move along the rotating axis.

[0052] It should be noted that the limiting plate 4212 and the rotating panel 421 are synchronous rotation, and there are various schemes for realizing the synchronous rotation of the limiting plate 4212 and the rotating panel 421, which are not limited in the present application. For example, in some embodiments, the clamping groove 4211 can be arranged only on the limiting plate 4212, and the limiting plate 4212 and the rotating panel 421 are connected and positioned by other structural members. In some other embodiments, the clamping groove 4211 can be arranged on the corresponding positions of the limiting plate 4212 and the rotating panel 421, and the clamping protrusion is clamped and matched with the limiting plate 4212 and the rotating panel 421.

And / or, the side wall of the damping groove 11 is formed with a grease containing groove 413, and when the plug-in section 411 extends into the damping groove 11, the damping grease can flow into the grease containing groove 413, and the damping grease will not overflow from the damping groove 11, in addition, the grease containing groove 413 actually also increases the contact area of the damping grease with the base 10, further enhancing the viscous feeling when the rotating assembly 20 rotates relative to the base 10.

[0064] In some embodiments, please refer to Figure 8 and Figure 9, in order to further improve the adjustability of the damping, the number of damping grooves 11 is two, and the two damping grooves 11 are concentrically arranged and can accommodate damping grease; the plug-in section 411 includes a first plug-in section 411 and a second plug-in section 411, and the first plug-in section 411 and the second plug-in section 411 are used to extend into different damping grooves 11.

[0065] In some embodiments of the damping adjustment assembly 40 including the elastic member 43, the elastic member 43 can be arranged only in one of the damping grooves 11, and in other embodiments, the elastic member 43 can also be arranged in both damping grooves 11, so that the force on the damping member 41 is more uniform, and the movement of the damping member 41 along the rotation axis is more stable.

[0066] It should be noted that in some embodiments, the damping grooves 11 are arranged on the base 10, and the plug-in section 411 can refer to a part of the structure of the damping member 41, or can refer to the entire damping member 41, which is determined by the structure of the damping member 41 itself.

[0068] In some embodiments, in the scheme in which the driving member 42 includes a rotary knob panel 421, a pressing panel 422 and a limiting plate 4212, in order to assist in positioning the damping member 41 and effectively avoid position deviation of the plug-in section 411 and the damping groove 11, please refer to Figure 5 and Figure 7 , the diameter of the limiting plate 4212 is greater than the diameter of the pressing panel 422, the side of the limiting plate 4212 facing the base 10 is provided with a limiting boss 4213, the limiting boss 4213 extends to the outer circumference of the ring-shaped damping member 41, along the radial direction of the limiting plate 4212, the limiting boss 4213 is located outside the pressing panel 422, the limiting boss 4213 and the damping member 41 are both located between the inner circumferential wall of the inner shell 232 and the connecting disc 2311, and the limiting plate 4212 limits the damping member 41 between the inner circumferential wall of the inner shell 232 and the connecting disc 2311 through the limiting boss 4213.

[0069] In some embodiments, in order to make full use of the structure of the limiting plate 4212 itself, the spring push bead 44 can be installed at the position of the limiting boss 4213, thereby effectively reducing the overall size and occupied space of the driving member 42 itself.

[0070] In some embodiments, please refer to the figure, the damping knob mechanism 200 can further include an angle sensing assembly 30, which includes a rotating piece 31 and a detection piece 32. The rotating piece 31 is fixed to the rotating assembly 20 and rotates synchronously with the rotating assembly 20. The detection piece 32 is fixed to the base 10 and is used to detect the rotation angle of the rotating piece 31, thereby detecting the relative rotation angle between the base 10 and the rotating assembly 20, so that the parameter change can be correspondingly controlled. Since the rotating piece 31 of the angle sensing assembly 30 rotates synchronously with the rotating assembly 20 as a whole, the rotating piece 31 and the detection piece 32 of the angle sensing assembly 30 can monitor the relative rotation of the base 10 and the rotating assembly 20 in real time and accurately, so as to improve the measurement accuracy and parameter adjustment accuracy of the damping knob mechanism 200.

[0071] In some embodiments, the rotating piece 31 is a magnet, and the detection piece 32 is a magnetic encoder used to detect the magnetic field change of the magnet. The detection piece 32 transmits the detection result to the processing chip of the focus remote controller 1000, and the processing chip controls the focus remote controller to perform the corresponding amplitude control action. Figure 5 The magnet can be embedded at one end of the connecting shaft 22 close to the base 10, and the magnetic encoder is fixed to the area corresponding to the base 10 and the connecting shaft 22.

[0072] Based on the same inventive concept, the application further provides a focus remote controller 1000, please refer to Figure 1 , which includes a remote controller body 100 and the damping knob mechanism 200 in the above embodiments. The base 10 of the damping knob mechanism 200 can be fixed to the remote controller body 100. The focus remote controller 1000 with the damping knob mechanism 200 naturally has all the beneficial effects described above, which will not be repeated here. The other structures of the focus remote controller 1000 can be referred to the related technology, which will not be described here.

[0073] In summary, the damping knob mechanism 200 and the focus remote controller 1000 provided by the application include two steps in use. First, fix the rotating assembly 20 so that the rotating assembly 20 does not rotate relative to the base 10. At this time, rotate the driving piece 42 to move the driving piece 42 and the damping piece 41 towards or away from the base 10, thereby changing the insertion depth of the insertion section 411 and the damping groove 11 to increase or decrease the damping accordingly. Second, drive the rotating assembly 20 to rotate relative to the base 10. The rotating assembly 20 drives the damping piece 41, the driving piece 42 and the rotating piece 31 to rotate. The detection piece 32 detects the rotation angle of the rotating assembly 20 and transmits the information to the control system of the remote controller body 100 to realize parameter adjustment control.

[0074] The damping knob mechanism 200 and the follow focus remote controller 1000 provided by the application improve the connection relationship and transmission relationship of each component, so that the rotating assembly 20 can only rotate as a whole relative to the base 10, and the rotating assembly 20 will not rotate during the process of pre-setting the damping size through the damping adjusting assembly 40, the rotating part 31 of the angle sensing assembly 30 keeps synchronous rotation with the rotating assembly 20 as a whole, so that the rotating part 31 and the detecting part 32 of the angle sensing assembly 30 can monitor the relative rotation condition of the base 10 and the rotating assembly 20 in real time and accurately, and the measurement accuracy and parameter adjustment accuracy of the damping knob mechanism 200 are effectively improved. Meanwhile, the damping groove 11 is provided with damping grease, the insertion depth of the insertion section 411 into the damping groove 11 is changed, the filling amount of the damping grease between the insertion section 411 and the damping groove 11 is also changed, and thus the friction force during the relative rotation of the damping part 41 and the base 10 can be changed. Since the damping part 41 and the rotating assembly 20 are synchronous, when the user operates to make the rotating assembly 20 rotate relative to the base 10, the damping stickiness feedback to the user is stronger, the hand feeling is better, the user can adjust the damping hand feeling to the required degree, and the adaptability and practicability of the damping knob mechanism 200 and the follow focus remote controller 1000 are improved.

According to the idea of the present application, skilled persons in the technical field to which the present application belongs can make several simple deductions, deformations or substitutions.
