Description

Pan / tilt rotation mechanism and pan / tilt Technical Field

[0001] The present invention relates to the technical field of photographic equipment, and in particular to a pan head rotating mechanism and a pan head using the pan head rotating mechanism. Background Art

[0002] The pan / tilt head refers to the supporting equipment for installing and fixing the camera. It is generally divided into fixed and electric types. The fixed pan / tilt head is suitable for situations where the monitoring range is small and requires manual adjustment. After installing the camera and other equipment on the fixed pan / tilt head, the horizontal and pitch angles of the camera can be adjusted. After reaching the optimal working state, the adjustment mechanism can be locked.

[0003] The existing RRS (Really Right Stuff) pan / tilt head is a fixed spherical pan / tilt head that can be used to mount cameras and other equipment. It covers a variety of 360-degree rotating pan / tilt head designs. For example, its BH-30 model spherical pan / tilt head has a rotating structure in which a single sphere with a clamp is rotatably mounted on a base 7. After the sphere is rotated to any position, the sphere is locked so that it cannot rotate relative to the base 7. When the clamp is connected to an external device and the load increases, the existing sphere cannot limit the pitch rotation of the sphere due to the load when the sphere is unlocked in this situation, which can easily cause the external device to break away from the clamp due to rapid rotation and cause damage.

[0004] Summary of the Invention

[0005] The main purpose of the present invention is to propose a pan-tilt rotation mechanism, which aims to solve the technical problem that the rotation structure of a single sphere in the prior art cannot limit the pitch rotation while providing a pan-tilt rotation solution.

[0006] To achieve the above objectives, the present invention provides a pan / tilt rotation mechanism, comprising:

[0007] A base having a mounting cavity therein;

[0008] The first rotating member includes a rotating part having at least a partially spherical surface, a connecting end connected to the upper part of the rotating part, and a limiting member connected to the lower part of the rotating part. The rotating part is rotatably arranged in the installation cavity, the connecting end is used to connect to an external device, and the limiting member is arranged in the installation cavity; the first rotating member can rotate horizontally and pitch relative to the base, and the limiting member is used to limit the pitch angle or pitch position of the first rotating member relative to the base.

[0009] In some embodiments, the limiting member is a rocker rod, and the rocker rod is rotatably connected to the rotating part.

[0010] In some embodiments, the rotating portion is provided with a connecting notch, and the rocker arm is connected to the connecting notch via a connecting shaft.

[0011] In some embodiments, an elastic member is further included in the mounting cavity and is sleeved with the rocker arm. When the first rotating member pitches relative to the base, the rocker arm squeezes the elastic member to cause the elastic member to undergo elastic deformation.

[0012] In some embodiments, the limiting member is an elastic rod.

[0013] In some embodiments, the pan / tilt rotating mechanism further includes a pressing member and a locking member;

[0014] The mounting cavity includes at least a first hemispherical cavity that matches the rotating part, and the interior of the holding piece is constructed with a second hemispherical cavity that matches the first hemispherical cavity. The first hemispherical cavity and the second hemispherical cavity match to limit the rotating part; the locking piece is used to lock the holding piece with the base.

[0015] In some embodiments, the locking member is provided with a locking handle.

[0016] In some embodiments, the locking member is threadedly connected to the base.

[0017] In some embodiments, the pan-tilt rotation mechanism further includes a base, the bottom of the base forms a second rotating member, and the second rotating member is rotatably connected to the base.

[0018] Furthermore, the present invention proposes a pan / tilt head, comprising the pan / tilt head rotation mechanism described above and a cold shoe mount 8 for clamping external equipment, wherein the cold shoe mount 8 is detachably connected to the other end of the first rotating member.

[0019] In the scheme of the present invention, when the angle of the pan-tilt rotation mechanism needs to be adjusted, an external force drives the first rotating member to rotate horizontally or in pitch, causing the partially spherical rotating portion of the first rotating member to rotate horizontally and / or in pitch within the mounting cavity. When the first rotating member is driven by an external force to rotate in pitch, the first rotating member driven by the external force can drive the limit member connected to it to swing within the mounting cavity, causing the end of the limit member away from the connection with the first rotating member to move toward the inner wall of the mounting cavity until the end of the limit member contacts the inner wall of the mounting cavity. At this time, the limit member limits the pitch angle or pitch position of the first rotating member relative to the base, and further application of driving force to drive the first rotating member cannot cause the first rotating member to continue to rotate in this direction. The present invention limits the pitch rotation of the first rotating member relative to the mounting cavity by means of a limit member provided in the mounting cavity of the base, so that its pitch rotation is kept within a certain range. While achieving horizontal rotation, it can also rotate in pitch in any direction other than the horizontal direction. The structure is simple, practical, and easy to operate.

[0030] 1 to 5 , the present invention provides a pan / tilt rotation mechanism, comprising:

[0031] The base 1 has a mounting cavity 10 therein;

[0032] The first rotating member 2 includes a rotating portion 20 having at least a partially spherical surface, a connecting end 21 connected to the upper portion of the rotating portion 20, and a limiting member 23 connected to the lower portion of the rotating portion 20. The rotating portion 20 is rotatably arranged in the installation cavity 10, the connecting end 21 is used to connect to external equipment, and the limiting member 23 is arranged in the installation cavity 10; the first rotating member 2 can rotate horizontally and pitch relative to the base 1, and the limiting member 23 is used to limit the pitch angle or pitch position of the first rotating member 2 relative to the base 1.

[0033] In this embodiment, the pan-tilt rotation mechanism of the present invention can adjust the second rotating member 11 to rotate the base 1 connected to the second rotating member 11 and the first rotating member 2 on the base 1 relative to the base 7 to achieve the appropriate angle required by the user. On this basis, the external device connected to the first rotating member 2 can be rotated horizontally or pitched by adjusting the first rotating member 2 relative to the base 1. The above-mentioned arrangement makes the angle adjustment form of the pan-tilt rotation mechanism of the present invention more diverse, which can meet the user's needs for various angle adjustments, with a simple structure and easy operation.

[0034] In the pan / tilt rotation mechanism of the present invention, when angle adjustment is required, an external force drives the first rotating member 2 to rotate horizontally or in pitch, causing the partially spherical rotating portion 20 of the first rotating member 2 to rotate horizontally and / or in pitch within the mounting cavity 10, that is, the first rotating member 2 rotates relative to the mounting cavity 10. When the first rotating member 2 is driven by any external force to rotate in either direction, the externally driven first rotating member 2 can drive the limit member 23 connected thereto to swing within the mounting cavity 10, causing the end of the limit member 23 away from the connection with the first rotating member 2 to move toward the inner wall of the mounting cavity 10. The first rotating member 2 is driven to rotate until this end of the limit member 23 contacts the inner wall of the mounting cavity 10. At this point, the limit member 23 limits the pitch angle or pitch position of the first rotating member 2 relative to the base 1. Continuing to apply a driving force to the first rotating member 2 prevents the first rotating member 2 from continuing to rotate in that direction. Reverse rotation causes the limit member 23 to move away from the inner wall of the mounting cavity 10, and the pitch angle is unrestricted. The present invention utilizes a stopper 23 disposed within the mounting cavity 10 of the base 1 to limit the pitch rotation of the first rotating member 2 relative to the mounting cavity 10, thereby maintaining the pitch rotation within a certain range. While achieving horizontal rotation, the device can also achieve pitch rotation in any direction other than the horizontal direction, resulting in a simple, practical structure and easy operation.

[0035] 2 , in some embodiments, the limiting member 23 provided in the present invention is a rocker rod, which is rotatably connected to the rotating portion 20 .

[0036] 3 , in some embodiments, the rotating portion 20 provided in the present invention is provided with a connecting notch 200 , and the rocker arm is connected to the connecting notch 200 via a connecting shaft 3 .

[0037] In the above embodiment, the first rotating member 2 is partially spherical. When the first rotating member 2 is driven by an external force to rotate in pitch, the first rotating member 2 causes the rocker arm, which is rotatably connected to it, to swing, causing the rocker arm to move away from the end of the first rotating member 2 toward the inner wall of the mounting cavity 10 until the rocker arm contacts the inner wall of the mounting cavity 10. At this point, the first rotating member 2 cannot rotate relative to the rocker arm, and the first rotating member 2 cannot be further moved in the direction of rotation by the external force. The rocker arm functions to limit the pitch angle of the second rotating body during pitch rotation. Specifically, when the first rotating member 2 is connected to an external device, the rocker arm acts as a limiter for the pitch rotation of the first rotating member 2 due to the weight of the external device.

[0038] Furthermore, the connecting shaft 3 and the rocker arm have an interference fit, meaning they are relatively fixed and cannot rotate relative to each other. When the first rotating member 2 is driven to pitch, the rocker arm swings accordingly until the first rotating member 2 rotates to the point where the rocker arm contacts the inner wall of the mounting cavity 10, at which point the first rotating member 2 cannot continue to pitch in the same direction. In this arrangement, the rotation angle of the first rotating member 2 is related to the cross-sectional width of the inner wall of the mounting cavity 10, or, if the cross-sectional width is fixed, to the cross-sectional width of the rocker arm.

[0039] In some embodiments, the arrangement of the first rotating member 2 and the rocker arm can also be the following arrangement: when the first rotating member 2 is driven to pitch and rotate, it drives the rocker arm connected to it to swing, so that the rocker arm moves away from one end of the first rotating member 2 toward the inner wall of the mounting cavity 10 until the end of the rocker arm contacts the inner wall of the mounting cavity 10, but at this time the first rotating member 2 can still rotate relative to the rocker arm, and continue to drive the first rotating member 2 in this direction until the first rotating member 2 reaches the physical limit position in this direction.

[0040] To further explain the arrangement of the first rotating member 2 and the rocker arm, when the connecting shaft 3 is tightly connected to the rocker arm, and when the first rotating member 2 is driven to pitch, the rocker arm can rotate relative to the first rotating member 2. After the first rotating member 2 is driven to rotate until the rocker arm contacts the inner wall of the mounting cavity 10, the first rotating member 2 continues to be driven to rotate in this direction, with the rocker arm maintaining contact with the inner wall of the mounting cavity 10, while the first rotating member 2 rotates relative to the rocker arm about the connecting shaft 3 until the physical rotation limit of the first rotating member 2 is reached. This design allows the rocker arm to provide a certain amount of cushioning when the first rotating member 2 pitches, but does not limit the pitch rotation angle.

[0041] In some embodiments, the swing arm is a vertical cylinder, with a connecting notch 200 recessed in the second rotating body. The connecting notch 200 can be positioned opposite the location where the external device is mounted on the first rotating member 2. A mounting hole is defined in the first rotating member 2, perpendicular to the swing direction of the swing arm and extending transversely through the connecting notch 200. The connecting shaft 3 is removably mounted in the mounting hole and has an interference fit, preventing it from rotating within the hole. A through-hole is also defined at one end of the swing arm, near the rotating body, for the connecting shaft 3 to pass through.

[0042] Regarding the installation steps, it should be noted that the rocker arm can be placed into the connecting notch 200 first, so that the through hole of the rocker arm and the mounting hole of the first rotating part 2 are aligned, and then the connecting shaft 3 is extended into the mounting hole from the outside of the mounting hole of the first rotating part 2 and installed through the through hole of the rocker arm.

[0043] It should be added that the cross-sectional width of one end of the rocker arm extending into the connecting notch 200 is adapted to the cross-sectional notch width of the connecting notch 200 , that is, the fit between the rocker arm and the connecting notch 200 is one of the following two: tight fit and clearance fit.

[0044] It should be explained that when the first rotating member 2 rotates horizontally, the limiting member 23 also rotates along with the rotating member, and the rotation center of the limiting member 23 is vertically collinear with the rotation center of the rotating member.

[0045] 2 , in some embodiments, the pan-tilt rotation mechanism proposed in the present invention further includes an elastic member 4 located in the mounting cavity 10 and sleeved with the rocker arm. When the first rotating member 2 pitches relative to the base 1 , the rocker arm squeezes the elastic member 4 so that the elastic member 4 undergoes elastic deformation.

[0046] In this embodiment, the rocker arm is connected to the inner wall of the mounting cavity 10 via an elastic member 4, which can be a spring. The operating principle of the elastic member 4 is that when the first rotating member 2 is driven to pitch and rotate, and this drives the rocker arm to swing, to ensure smooth swinging, the elastic member 4 is added to the pan / tilt rotation mechanism of the present invention to provide a certain buffering force, thereby making the swinging speed of the rocker arm slow. There are several design options:

[0047] First, when the first rotating member 2 and the connecting shaft 3 are designed to fit tightly, regardless of whether the direction in which the first rotating member 2 is driven to rotate is consistent with the direction in which the rocker arm can swing in the connecting notch 200, the rocker arm is reset to its initial vertical state under the influence of the elastic force applied by the spring, and the first rotating member 2 is also reset along with the rocker arm. This design realizes the rapid reset function of the first rotating member 2.

[0048] Secondly, when the first rotating member 2 and the connecting shaft 3 are designed to have a clearance fit, the rocker arm is reset to its initial vertical position due to the elastic force applied by the spring. Only when the first rotating member 2 is driven to rotate in a direction inconsistent with the swing direction of the rocker arm within the connecting notch 200, the rocker arm is reset to its initial vertical position due to the elastic force applied by the spring, and the first rotating member 2 is also reset with the rocker arm. When the first rotating member 2 is driven to rotate in pitch, this design enables the first rotating member 2 to quickly reset only when its driven rotation direction is inconsistent with the swing direction of the rocker arm within the connecting notch 200.

[0049] In some embodiments, a first supporting portion is protruding outward from the outer wall of the rocker arm, a second supporting portion is protruding inward from the inner wall of the second rotating member 11 provided in the middle shell, and the elastic member 4 sleeved on the rocker arm is provided between the first supporting portion and the second supporting portion, and the two ends of the elastic member 4 respectively abut against the first supporting portion and the second supporting portion.

[0050] In some embodiments, the first abutting portion can be replaced by an annular member whose inner diameter matches the diameter of the rocker arm. The spring is first sleeved on the rocker arm, and then the spring is confined between the annular member and the first rotating member 2 by sleeved on the rocker arm in a tight fit.

[0051] In some embodiments, the limiting member 23 provided in the present invention is an elastic rod.

[0052] In this embodiment, the material of the limiting member 23 can be selected to be a material that has both elasticity and a certain degree of plasticity. When one end of the limiting member 23 swings and contacts the inner wall of the installation cavity 10 due to the pitch rotation of the first rotating member 2, the elastic rod itself will undergo a certain deformation. When the first driving member is in a state where no external force is applied to it and it can rotate relative to the installation cavity 10, the deformed elastic rod will rebound and return to its state before deformation, away from the inner wall of the installation cavity 10.

[0053] 2 , 4 and 5 , in some embodiments, the pan / tilt rotation mechanism of the present invention further includes a pressing member 5 and a locking member 6 ;

[0054] The mounting cavity 10 includes at least a first hemispherical cavity 101 that matches the rotating part, and the interior of the holding member 5 is constructed with a second hemispherical cavity 50 that matches the first hemispherical cavity 101. The first hemispherical cavity 101 and the second hemispherical cavity 50 cooperate to limit the rotating part 20; the locking member 6 is used to lock the holding member 5 with the base 1.

[0055] In this embodiment, after the rotation angle of the first rotating member 2 is adjusted, the locking member 6 is driven by an external force, which drives the holding member 5 connected thereto to move toward the first rotating member 2. The holding member 5 contacts the first rotating member 2 and, as the locking member 6 continues to be driven by the external force, contacts the first rotating member 2. The holding member 5 presses against the first hemispherical cavity 101 until the first rotating member 2 is in a non-rotatable state relative to the locking member 6 and the first hemispherical cavity 101. To unlock the first rotating member 2, the locking member 6 is driven in the opposite direction so that the holding member 5 no longer presses the first rotating member 2 against the inner wall of the mounting cavity 10. The first rotating member 2 is then in a rotatable state, capable of rotating relative to the inner wall of the mounting cavity 10.

[0056] In some embodiments, the holding member 5 has a through hole for extending from one end of the first rotating member 2 to connect to the external device. The holding member 5 in the stop assembly and the holding member 5 can be an integrally formed part. The split design in the above embodiment in which the holding member 5 is sleeved on the outside of the holding member 5 is for easy disassembly. When the first rotating member 2 with a different spherical diameter needs to be replaced, the size of the through hole on the corresponding holding member 5 is also different. At this time, it is necessary to replace the holding member 5 with a spherical diameter that is suitable for the first rotating member 2.

[0057] It should be noted that in some embodiments, the diameter of the through hole of the pressing member 5 must be smaller than the diameter of the sphere of the first rotating member 2, that is, the diameter of the through hole cannot be greater than or equal to the diameter of the first rotating member 2. This design is intended to enable the pressing member 5 to more securely press the first rotating member 2 against the inner wall of the mounting cavity 10.

[0058] Specifically, the installation cavity 10 also includes a accommodating cavity 102 connected to the first hemispherical cavity. The first rotating member 2 is accommodated in the first hemispherical cavity. One end of the rocker arm extends into the first hemispherical cavity 101 to connect to the first rotating member 2, and the other end is accommodated in the accommodating cavity 102. When the first rotating member 2 rotates to drive the rocker arm to swing, one end of the rocker arm set in the accommodating cavity 102 abuts against or moves away from the inner wall of the accommodating cavity 102.

[0059] In some embodiments, due to the cavity shaping principle, a transition point inevitably exists between two interconnected cavities of different shapes. Since the rocker arm extends into the first hemispherical cavity 101 to connect with the first rotating member 2, a portion of the rocker arm located between the first hemispherical cavity 101 and the accommodating cavity 102 may contact the transition point as the first rotating member 2 rotates. Considering the mating relationship between the rocker arm and the connecting shaft 3 and the cross-sectional width of the accommodating cavity 102, the rocker arm may not contact the inner wall of the accommodating cavity 102, but instead contact the transition point between the upper accommodating cavities 102. When the rocker arm contacts the transition point, the first rotating member 2 cannot continue to be driven in a certain direction.

[0060] 4 , in some embodiments, the locking member 6 provided in the present invention is provided with a locking handle 61 .

[0061] 2 , 4 and 5 , in some embodiments, the locking member 6 proposed in the present invention is threadedly connected to the base 1 .

[0062] In the above embodiment, after the rotating body is rotated to the desired angle, a force parallel to the horizontal direction is applied to the locking handle 61. This force is applied to drive the pressing member 5, which can also be referred to as rotating the pressing member 5, so that the threads on the outer wall of the base 1 and the inner wall of the pressing member 5 begin to engage. As the pressing member 5 continues to rotate, the pressing member 5 drives the pressing member 5 toward the first rotating member 2 in contact with the pressing member 5 until the second hemispherical cavity 50 of the pressing member 5 presses the first rotating member 2 against the first hemispherical cavity 101, i.e., the first rotating member 2 becomes non-rotatable. The further rotation of the pressing member 5 is stopped, and the rotating body is fixed after the rotating body has rotated to the desired angle. If further adjustment of the rotating body's angle is required, the locking handle 61 is loosened by applying a force opposite to the force described above in this embodiment, so that the second hemispherical cavity 50 of the pressing member 5 no longer presses against the first rotating member 2. After adjusting the angle of the first rotating member 2 again, the pressing member 5 is tightened again to press the pressing member 5 against the first rotating member 2.

[0063] In some embodiments, the locking member 6, the base 1, and the holding member 5 of the present invention can be designed in the following ways without considering the ease of replacing the first rotating member 2 or the ease of adjusting the angle of the first rotating member 2:

[0064] First, the arrangement of the pressing member 5 and the base 1 remains unchanged, and the pressing member 5 and the base 1 are integrated.

[0065] As an extension of this, when the holding member 5 is integrated with the base 1, the base 1 can be provided with a plurality of machine screw (top screw) holes, each of which is connected to the inner wall of the mounting cavity 10. At this time, the holding member 5 is a machine screw, and the machine screw is screwed into the machine screw hole so that each machine screw abuts against the first rotating member 2 in the inner wall of the mounting cavity 10, thereby fixing the first rotating member 2 so that it cannot rotate relative to the inner wall of the mounting cavity 10.

[0066] Second: the setting form of the holding member 5 remains unchanged, and the locking member 6 is connected to the base 1 by bolts, that is, the base 1 is provided with a vertical threaded hole, and the locking member 6 is also provided with a countersunk through hole opposite to the threaded hole of the base 1. The bolt is passed through the countersunk through hole of the locking member 6 and is screwed to the threaded hole on the base 1 for fixation. By tightening or loosening the bolt, the locking member 6 is controlled to press the first rotating member 2 against the first hemispherical cavity 101.

[0067] As a second extension, the pressing member 5 and the pressing member 5 can be provided in an integrated manner.

[0068] In some embodiments, the holding member 5 is annular and has a through hole for one end of the first rotating member 2 to connect to the external device. The through hole is connected to the second hemispherical cavity 50. The second hemispherical cavity 50 partially accommodates the first rotating member 2. The outer wall of the holding member 5 is provided with an annular belt protruding outward, and the inner wall of the locking member 6 is constructed with a stepped portion adapted to the annular belt. The holding member 5 can rotate relative to the locking member 6.

[0069] When the locking member 6 is in the vertical direction, the locking member 6 is locked and the locking member 6 is locked.

[0070] 5 , in some embodiments, the pan / tilt rotation mechanism of the present invention further includes a base 7 , and a second rotating member 11 is formed at the bottom of the base 1 , and the second rotating member 11 is rotatably connected to the base 7 .

[0071] In this embodiment, the pan-tilt rotation mechanism of the present invention can rotate the pan-tilt rotation mechanism relative to the base 7 by adjusting the second rotating member 11 to achieve the appropriate angle required by the user. On this basis, the external device connected to the first rotating member 2 can be rotated horizontally or pitched by adjusting the first rotating member 2 relative to the base 1. The second rotating member 11 is located at one end of the base 7 and is a sphere that can be adapted to a common base 7 with a spherical cavity. The size of the sphere of the second rotating member 11 can be designed according to actual needs.

[0072] In some embodiments, the base 7 may also utilize locking components and designs to restrict the spherical portion of the second rotating member 11, allowing the spherical portion of the second rotating member 11 to be rotatable or immobile relative to the base 7. The design of this design may also refer to the arrangement of the base 1, the holding member 5, and the locking member 6 in the aforementioned embodiments, and will not be further described here.

[0073] 1 and 2 , the present invention further provides a pan / tilt head comprising the pan / tilt head rotation mechanism described in the aforementioned embodiments and a cold shoe mount 8 for clamping an external device, wherein the cold shoe mount 8 is detachably connected to the other end of the first rotating member 2 . The specific structure of the pan / tilt head rotation mechanism is similar to that of the aforementioned embodiments. Since the pan / tilt head utilizes all the technical solutions of all the aforementioned embodiments, it at least possesses all the technical effects brought about by the technical solutions of the aforementioned embodiments, and therefore will not be further elaborated here.

[0074] In this embodiment, the two cold shoe mounts 8 can be controlled to move toward each other to clamp the camera equipment or move away from each other to release the camera equipment, thereby locking the external equipment to the pan / tilt head. The implementation method can be spring-driven or can be designed according to the actual needs of those skilled in the art, and is not limited here.

[0075] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. Any equivalent structural transformation made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields, is included in the scope of protection of the present invention.
