[0015] In this invention, the gimbal rotation mechanism, when angle adjustment is required, is driven by an external force to rotate the first rotating component horizontally or in pitch, causing a portion of the spherical rotating part of the first rotating component to rotate horizontally and/or in pitch within the mounting cavity. When the first rotating component is driven by an external force to rotate in pitch, the first rotating component driven by the external force can cause the limiting component connected to it to swing within the mounting cavity, causing the end of the limiting component away from the first rotating component to move towards the inner wall of the mounting cavity until that end of the limiting component contacts the inner wall of the mounting cavity. At this time, the limiting component restricts the pitch angle or pitch position of the first rotating component relative to the base, and when the driving force is continued to be applied to drive the first rotating component, it cannot continue to rotate in that direction. This invention restricts the pitch rotation of the first rotating component relative to the mounting cavity by a limiting component set in the mounting cavity of the base, keeping its pitch rotation within a certain range. While achieving horizontal rotation, it can also pitch rotation in any direction other than the horizontal direction, with a simple and practical structure and easy operation.

Abstract
Description
Technical Field
[0001] This invention relates to the field of photographic equipment technology, and in particular to a gimbal rotation mechanism and a gimbal using the gimbal rotation mechanism. Background Technology
[0002] A pan-tilt unit (PTZ) is a support device for mounting and fixing cameras. It is generally divided into fixed and motorized types. Fixed PTZs are suitable for situations where the monitoring range is small and require manual adjustment. After installing cameras and other equipment on a fixed PTZ, the horizontal and vertical angles of the cameras can be adjusted to achieve the best working state, and then the adjustment mechanism can be locked.
[0003] The existing RRS (Really Right Stuff) pan-tilt head is a fixed ball head that can be used to mount equipment such as cameras. It covers a variety of 360-degree rotating pan-tilt head designs, such as the BH-30 model ball head. Its structure is a rotating structure with a clamp on a base 7. After the ball is rotated to any position, it is locked so that it cannot rotate relative to the base 7. When the clamp is connected to external equipment, the load increases. In this case, the existing ball head cannot limit the pitch rotation of the ball due to the load when unlocking the ball. This can easily cause the external equipment to fall off the clamp due to rapid rotation and be damaged. Summary of the Invention
[0004] The main objective of this invention is to propose a gimbal rotation mechanism that addresses the technical problem that existing gimbal rotation structures, which rely on a single rotating sphere, cannot simultaneously limit pitch rotation while providing a gimbal rotation solution.
[0005] To achieve the above objectives, the present invention proposes a gimbal rotation mechanism, comprising: The base has an internal mounting cavity; The first rotating member includes a rotating part having at least a partial 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 disposed within the mounting cavity. The connecting end is used to connect to an external device, and the limiting member is disposed in the mounting cavity. The first rotating member can rotate horizontally and pitch relative to the base. The limiting member is used to limit the pitch angle or pitch position of the first rotating member relative to the base.
[0006] In some embodiments, the limiting member is a rocker arm, which is rotatably connected to the rotating part.
[0007] In some embodiments, the rotating part is provided with a connecting notch, and the rocker arm is connected to the connecting notch via a connecting shaft.
[0008] In some embodiments, an elastic element located within the mounting cavity and sleeved with the swing arm is further included. When the first rotating member pitches relative to the base, the swing arm compresses the elastic element, causing the elastic element to undergo elastic deformation.
[0009] In some embodiments, the limiting member is an elastic rod.
[0010] In some embodiments, the gimbal rotation mechanism further includes a holding member and a locking member; The mounting cavity includes at least a first hemispherical cavity that mates with the rotating part, and the holding member has a second hemispherical cavity that mates with the first hemispherical cavity. The first hemispherical cavity and the second hemispherical cavity mate to restrict the rotating part; the locking member is used to lock the holding member to the base.
[0011] In some embodiments, the locking member is provided with a locking handle.
[0012] In some embodiments, the locking member is threadedly connected to the base.
[0013] In some embodiments, the gimbal rotation mechanism further includes a base, the bottom of which forms a second rotating member, which is rotatably connected to the base.
[0014] Furthermore, the present invention proposes a gimbal, including the gimbal rotation mechanism described above and a cold shoe mount 8 for clamping external devices, wherein the cold shoe mount 8 is detachably connected to the other end of the first rotating member.
[0015] In this invention, the gimbal rotation mechanism, when angle adjustment is required, is driven by an external force to rotate the first rotating component horizontally or in pitch, causing a portion of the spherical rotating part of the first rotating component to rotate horizontally and / or in pitch within the mounting cavity. When the first rotating component is driven by an external force to rotate in pitch, the first rotating component driven by the external force can cause the limiting component connected to it to swing within the mounting cavity, causing the end of the limiting component away from the first rotating component to move towards the inner wall of the mounting cavity until that end of the limiting component contacts the inner wall of the mounting cavity. At this time, the limiting component restricts the pitch angle or pitch position of the first rotating component relative to the base, and when the driving force is continued to be applied to drive the first rotating component, it cannot continue to rotate in that direction. This invention restricts the pitch rotation of the first rotating component relative to the mounting cavity by a limiting component set in the mounting cavity of the base, keeping its pitch rotation within a certain range. While achieving horizontal rotation, it can also pitch rotation in any direction other than the horizontal direction, with a simple and practical structure and easy operation.

Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0022] Reference Figures 1 to 5 This invention proposes a gimbal rotation mechanism, comprising: Base 1, with an internal mounting cavity 10; The first rotating member 2 includes a rotating part 20 having at least a partial spherical surface, a connecting end 21 connecting the upper part of the rotating part 20, and a limiting member 23 connecting the lower part of the rotating part 20. The rotating part 20 is rotatably disposed in the mounting cavity 10. The connecting end 21 is used to connect to external equipment, and the limiting member 23 is disposed in the mounting cavity 10. The first rotating member 2 can rotate horizontally and pitch relative to the base 1. 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.
[0023] In this embodiment, the gimbal rotation mechanism of the present invention can adjust the second rotating member 11 to make the base 1 connected to the second rotating member 11 and the first rotating member 2 on the base 1 rotate 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 made to rotate horizontally or tilted relative to the base 1 by adjusting the first rotating member 2 to rotate horizontally or tilted. The above-mentioned settings make the angle adjustment forms of the gimbal rotation mechanism of the present invention more abundant, which can meet the user's needs for multiple angle adjustments. The structure is simple and the operation is convenient.
[0024] In this invention, the gimbal rotation mechanism allows for angle adjustment. An external force drives the first rotating member 2 to rotate horizontally or pitch, causing the spherical rotating portion 20 of the first rotating member 2 to rotate horizontally and / or pitch within the mounting cavity 10. In other words, 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 pitch in any direction, the first rotating member 2, driven by the external force, can cause the connected limiting member 23 to swing within the mounting cavity 10. This causes the end of the limiting member 23 away from the first rotating member 2 to move towards the inner wall of the mounting cavity 10. The first rotating member 2 is driven to rotate until this end of the limiting member 23 contacts the inner wall of the mounting cavity 10. At this point, the limiting member 23 restricts the pitch angle or pitch position of the first rotating member 2 relative to the base 1. Continuing to apply a driving force to drive the first rotating member 2 prevents it from continuing to rotate in that direction. Reverse rotation causes the limiting member 23 to move away from the inner wall of the mounting cavity 10, and the pitch angle is no longer restricted. This invention limits the pitch rotation of the first rotating member 2 relative to the mounting cavity 10 by a limiting member 23 disposed within the mounting cavity 10 of the base 1, thus keeping its pitch rotation within a certain range. While achieving horizontal rotation, it can also pitch rotate in any direction other than the horizontal direction. The structure is simple, practical, and easy to operate.
[0025] Reference Figure 2 In some embodiments, the limiting member 23 proposed in this invention is a rocker arm, which is rotatably connected to the rotating part 20.
[0026] Reference Figure 3In some embodiments, the rotating part 20 proposed in this invention is provided with a connecting notch 200, and the swing arm is connected to the connecting notch 200 through the connecting shaft 3.
[0027] 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 pitch and rotate, it drives the swing arm rotatably connected to it to swing, causing the end of the swing arm away from the first rotating member 2 to move towards the inner wall of the mounting cavity 10 until the swing arm contacts the inner wall of the mounting cavity 10. At this point, the first rotating member 2 cannot rotate relative to the swing arm, and therefore the first rotating member 2 cannot be moved further in the direction of rotation by an external force. The function of the swing arm is to limit the pitch angle of the pitch-rotating first rotating member 2. That is, when the first rotating member 2 is connected to an external device, the first rotating member 2 may pitch and rotate due to the weight of the external device, and the swing arm acts as a limiter for the pitch rotation of the first rotating member 2.
[0028] Furthermore, the connecting shaft 3 and the rocker arm are interference-fitted, meaning they are relatively fixed and cannot rotate relative to each other. When the first rotating component 2 is driven to pitch, the rocker arm swings accordingly until the first rotating component 2 rotates to the point where the rocker arm contacts the inner wall of the mounting cavity 10, at which point the first rotating component 2 can no longer pitch in the same direction. In this configuration, the rotation angle of the first rotating component 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, is related to the cross-sectional width of the rocker arm.
[0029] In some embodiments, the arrangement of the first rotating member 2 and the rocker arm can also be as follows: when the first rotating member 2 is driven to pitch and rotate, it causes the rocker arm rotatably connected to it to swing, so that the end of the rocker arm away from the first rotating member 2 moves 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. However, at this time, the first rotating member 2 can still rotate relative to the rocker arm, and the first rotating member 2 can continue to be driven in this direction until the first rotating member 2 reaches the physical limit position in this direction.
[0030] 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 that direction, while the rocker arm remains in contact with the inner wall of the mounting cavity 10. The first rotating member 2 rotates relative to the rocker arm around the connecting shaft 3 until it reaches its physical rotation limit. This design allows the rocker arm to provide some cushioning during the pitch rotation of the first rotating member 2, but it does not limit the angle of pitch rotation.
[0031] In some embodiments, the swing arm is a vertical cylinder, and a connecting notch 200 is recessed in the first rotating member 2. The connecting notch 200 can be positioned opposite to the position where external equipment is mounted on the first rotating member 2. The first rotating member 2 has a mounting hole, the direction of which is perpendicular to the swing direction of the swing arm, and the mounting hole passes through the connecting notch 200. The connecting shaft 3 is detachably mounted in the mounting hole and is interference-fitted with the mounting hole, meaning that the connecting shaft 3 cannot rotate within the mounting hole. A through hole is also provided at the end of the swing arm near the rotating body for the connecting shaft 3 to pass through.
[0032] 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. Then, the connecting shaft 3 is inserted 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.
[0033] It should be added that the end of the rocker arm that extends into the connecting notch 200 has a cross-sectional width that matches 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 or clearance fit.
[0034] It should be explained that when the first rotating member 2 rotates horizontally, the limiting member 23 also rotates with the rotating member, and the rotation center of the limiting member 23 is vertically collinear with the rotation center of the rotating member.
[0035] Reference Figure 2 In some embodiments, the gimbal rotation mechanism proposed in this invention further includes an elastic element 4 located in the mounting cavity 10 and sleeved with the swing arm. When the first rotating element 2 pitches relative to the base 1, the swing arm squeezes the elastic element 4, causing the elastic element 4 to undergo elastic deformation.
[0036] In this embodiment, the swing arm is connected to the inner wall of the mounting cavity 10 by an elastic element 4, which can be a spring. The working principle of the elastic element 4 is as follows: when the first rotating member 2 is driven to pitch and rotate, causing the swing arm to swing, to ensure smooth swinging, the elastic element 4 is added to the gimbal rotation mechanism of this invention to provide a certain buffering force, thus smoothing the swing arm's swing speed. Several design options are available: Firstly, when the first rotating component 2 and the connecting shaft 3 are designed to fit tightly together, regardless of whether the direction in which the first rotating component 2 is driven to rotate is consistent with the direction in which the rocker arm can swing within the connecting notch 200, the rocker arm is reset to its initial vertical state under the influence of the spring force applied by the spring, and the first rotating component 2 is also reset along with the rocker arm. This design realizes the quick reset function of the first rotating component 2.
[0037] Secondly, when the first rotating component 2 and the connecting shaft 3 are designed with a clearance fit, the rocker arm is reset to its initial vertical state under the influence of the spring force. Only when the direction in which the first rotating component 2 is driven to rotate is inconsistent with the direction in which the rocker arm can swing within the connecting notch 200, the rocker arm is reset to its initial vertical state under the influence of the spring force, and the first rotating component 2 also resets with the rocker arm. When the first rotating component 2 is driven to pitch, this design achieves the function of rapid reset of the first rotating component 2 only when the direction in which it is driven to rotate is inconsistent with the direction in which the rocker arm can swing within the connecting notch 200.
[0038] In some embodiments, the outer wall of the rocker arm protrudes outward to form a first abutment portion, the inner wall of the second rotating member 11 in the middle shell protrudes inward to form a second abutment portion, and the elastic member 4 sleeved on the rocker arm is disposed between the first abutment portion and the second abutment portion, with the two ends of the elastic member 4 abutting against the first abutment portion and the second abutment portion respectively.
[0039] In some embodiments, the first abutment can be replaced by an annular member whose inner diameter is adapted to the diameter of the rocker arm. The spring is first sleeved on the rocker arm, and then the spring is restricted between the annular member and the first rotating member 2 by tightly fitting the annular member onto the rocker arm.
[0040] In some embodiments, the limiting member 23 proposed in this invention is an elastic rod.
[0041] In this embodiment, the material of the limiting member 23 can be selected as 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 mounting cavity 10 due to the pitching 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 mounting cavity 10, the deformed elastic rod will rebound and return to the state before the deformation, moving away from the inner wall of the mounting cavity 10.
[0042] Reference Figure 2 , Figure 4 and Figure 5 In some embodiments, the gimbal rotation mechanism proposed in this invention further includes a pressing member 5 and a locking member 6; The mounting cavity 10 includes at least a first hemispherical cavity 101 that cooperates with the rotating part. The holding member 5 has a second hemispherical cavity 50 that cooperates with the first hemispherical cavity 101. The first hemispherical cavity 101 and the second hemispherical cavity 50 cooperate to restrict the rotating part 20. The locking member 6 is used to lock the holding member 5 to the base 1.
[0043] In this embodiment, after the rotation angle of the first rotating member 2 is adjusted, the locking member 6 is driven by external force. The locking member 6 drives the pressure member 5 connected to it to move towards the first rotating member 2. The pressure member 5 contacts the first rotating member 2 and continues to contact the first rotating member 2 as the locking member 6 is driven by external force. The pressure member 5 presses 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. When the first rotating member 2 is unlocked, the locking member 6 is driven in the opposite direction, so that the pressure 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 that can rotate relative to the inner wall of the mounting cavity 10.
[0044] In some embodiments, the holding member 5 has a through hole for the end of the first rotating member 2 to be connected to an external device to extend out. The holding member 5 and the locking member 6 in the stop assembly can be integrally formed parts. The split design in the above embodiments, in which the locking member 6 is sleeved on the outside of the holding member 5, is for easy disassembly. When it is necessary to replace the first rotating member 2 with a different ball diameter, 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 ball diameter that is compatible with the first rotating member 2.
[0045] 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. The purpose of this design is to allow the pressing member 5 to more reliably press the first rotating member 2 against the inner wall of the mounting cavity 10.
[0046] Specifically, the mounting cavity 10 also includes a receiving cavity 102 that communicates with the first hemispherical cavity. The first rotating member 2 is housed in the first hemispherical cavity. One end of the swing rod extends into the first hemispherical cavity 101 and connects to the first rotating member 2. The other end is housed in the receiving cavity 102. When the first rotating member 2 rotates and drives the swing rod to swing, one end of the swing rod is positioned in the receiving cavity 102 and abuts against or moves away from the inner wall of the receiving cavity 102.
[0047] In some embodiments, due to the shaping principle of the cavities, there must be a transition position between two cavities of different shapes that are interconnected. 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 receiving cavity 102 may come into contact with the transition position as the first rotating member 2 rotates. At this time, the fit between the rocker arm and the connecting shaft 3 and the cross-sectional cavity width of the receiving cavity 102 need to be considered. The rocker arm may not contact the inner wall of the receiving cavity 102, but instead contacts the transition position between the upper receiving cavities 102. When the rocker arm contacts the transition position, the first rotating member 2 cannot continue to be driven in a certain direction.
[0048] Reference Figure 4In some embodiments, the locking member 6 proposed in this invention is provided with a locking handle 61.
[0049] Reference Figure 2 , Figure 4 and Figure 5 In some embodiments, the locking member 6 proposed in this invention is threadedly connected to the base 1.
[0050] In the above embodiment, after the rotating body is rotated to the required angle, a force parallel to the horizontal direction is applied to the locking handle 61. The process of applying force to drive the holding member 5 can also be called rotating the holding member 5, so that the threads on the outer wall of the base 1 and the inner wall of the holding member 5 begin to engage. As the holding member 5 continues to rotate, the locking member 6 drives the holding member 5 to move toward the first rotating member 2 that is in contact with the holding member 5, until the second hemispherical cavity 50 of the holding member 5 presses the first rotating member 2 into the first hemispherical cavity 101, that is, the first rotating member 2 is in a non-rotatable state. Then, the rotation of the holding member 5 is stopped, and the rotating body is fixed after rotating to the required angle. When it is necessary to continue to adjust the angle of the rotating body, a force opposite to the force described above in this embodiment is applied to loosen the locking handle 61, so that the second hemispherical cavity 50 of the holding member 5 no longer presses the first rotating member 2. After adjusting the angle of the first rotating member 2 again, the locking member 6 is tightened again to drive the holding member 5 to press the first rotating member 2.
[0051] In some embodiments, the locking member 6, the base 1, and the pressing 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: Firstly, the arrangement of the pressing member 5 and the base 1 remains unchanged, while the pressing member 5 and the base 1 are integrated.
[0052] As an extension, when the holding member 5 is integrated with the base 1, the base 1 can have multiple grommets (set screws) holes. Each grommet hole is connected to the inner wall of the mounting cavity 10. At this time, the holding member 5 is a grommet. By screwing the grommets into the grommet holes, each grommet abuts against the first rotating member 2 inside the inner wall of the mounting cavity 10, fixing the first rotating member 2 so that it cannot rotate relative to the inner wall of the mounting cavity 10.
[0053] Secondly, the setting of the holding member 5 remains unchanged. The locking member 6 is connected to the base 1 by bolts. That is, the base 1 has a vertical threaded hole, and the locking member 6 also has a countersunk through hole opposite to the threaded hole of the base 1. The locking member 6 is fixed by bolts passing through the countersunk through hole of the locking member 6 and screwing it into the threaded hole on the base 1. The locking member 6 presses the first rotating member 2 into the first hemispherical cavity 101 by tightening or loosening the bolts.
[0054] As an extension of this, the holding member 5 and the locking member 6 can be integrated into one unit.
[0055] In some embodiments, the holding member 5 is annular and has a through hole through which one end of the first rotating member 2 is connected to an external device. The through hole communicates with the second hemispherical cavity 50, which partially accommodates the first rotating member 2. The outer wall of the holding member 5 is provided with an outwardly protruding ring band, and the inner wall of the locking member 6 is constructed with a stepped portion adapted to the ring band. The holding member 5 can rotate relative to the locking member 6.
[0056] The ring band protruding outward from the outer wall of the holding member 5 and the stepped portion adapted to the inner wall of the locking member 6 are constructed so that the holding member 5 is constrained by the horizontal displacement of the inner wall of the locking member 6 as well as by the vertical displacement of the locking member 6. That is, when the locking member 6 is driven by an external force to drive the holding member 5 to move, the holding member 5 contacts the first rotating member 2 and presses the first rotating member 2 into the first hemispherical cavity 101. Since the contoured portion of the locking member 6 indirectly applies pressure to the first rotating member 2, the first rotating member 2 also has a reaction force on the holding member 5 in the opposite direction of the above pressure. This reaction force is vertical to the pressed surface of the first rotating member 2 and will indirectly drive the holding member 5 to disengage from the locking member 6. At this time, the mutual cooperation structure of the stepped portion and the ring band restricts the further movement of the holding member 5 from disengaging from the locking member 6 and maintains the relative positional relationship between the holding member 5 and the locking member 6.
[0057] Reference Figure 5 In some embodiments, the gimbal rotation mechanism proposed in this 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.
[0058] In this embodiment, the gimbal rotation mechanism of the present invention can be adjusted by adjusting the second rotating member 11 to rotate the gimbal rotation mechanism 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 adjusted to rotate horizontally or tilted relative to the base 1 by adjusting the first rotating member 2 to rotate horizontally or tilted. The second rotating member 11 is a sphere at one end of the base 7, which can be adapted to common bases 7 with spherical cavities. The size of the sphere of the second rotating member 11 can be designed according to actual needs.
[0059] In some embodiments, the spherical portion of the second rotating member 11 can also be restricted by some components and designs with locking functions on the base 7, so that the spherical portion of the second rotating member 11 is rotatable or non-rotatable relative to the base 7. Its design can also refer to the arrangement of the base 1, the holding member 5 and the locking member 6 in the foregoing embodiments, and will not be described in detail here.
[0060] Reference Figure 1 and Figure 2The present invention further proposes a gimbal, including the gimbal rotation mechanism described in the foregoing embodiments and a cold shoe mount 8 for clamping external devices, wherein the cold shoe mount 8 is detachably connected to the other end of the first rotating member 2. The specific structure of the gimbal rotation mechanism is as described in the above embodiments. Since the gimbal adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
[0061] In this embodiment, the camera equipment can be locked to the pan-tilt unit by controlling the two cold shoe mounts 8 to move towards each other to clamp the camera equipment or to move away from each other to release the camera equipment. This can be achieved through spring drive, or by designing according to the actual needs of those skilled in the art, and is not limited here.
