Description

Technical Field

[0001] This application relates to the technical field of photographic supports, and particularly to a dual panoramic pan-tilt head and a photographic equipment support. Background Art

[0002] With the continuous development of today's social media, people need to use different photographic equipment in different scenarios, which makes photographic equipment and accessories such as single-lens reflex cameras, mobile phones, and tripods increasingly enter people's daily lives. When shooting outdoors, the photographer often needs to hold the camera by hand and continuously maintain a proper posture, but it is easy for the hand to get tired after maintaining a posture for a long time. Therefore, in common photographic operations, the photographer will use a tripod to assist in stabilizing the photographic equipment, or first install the photographic equipment on a pan-tilt head, and then rotate the pan-tilt head and set it on the tripod, so as to realize the pan-tilt head driving the photographic equipment to rotate relative to the tripod to adjust the photographic angle. This method enables the pan-tilt head to only be adjusted in one direction on the tripod. When shooting outdoors, the single adjustment of the photographic angle often depends on the absolute level of the tripod fulcrum, and it is difficult for the tripod to maintain stability on an inclined ground or in a non-planar scene. If the pitch angle needs to be adjusted, the tripod level needs to be recalibrated, and the tripod cannot compensate for the inclination of the photographic equipment and the ground. Therefore, the traditional tripod has poor adaptability when used outdoors. Summary of the Invention

[0003] Objective: To overcome the deficiencies in the prior art, the present invention provides a dual panoramic pan-tilt head and a photographic equipment support, which can achieve the tilt compensation between the photographic equipment and the ground, and has high adjustment flexibility and strong stability.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, the present invention provides a dual panoramic pan-tilt head, including a base, a motor, and a control mechanism; The base is used to carry the photographic equipment; The control mechanism includes a mounting seat, a control cross column, and an adjustment column. The mounting seat is a U-shaped structure, and a first gear is installed on the bottom surface; a second gear meshing with the first gear is sleeved at one end of the control cross column, and the control cross column is rotatably installed inside the mounting seat; one end of the adjustment column is installed outside the control cross column, and the other end is fixedly connected to the base; it is used to adjust the pitch angle of the base. The motor is installed at the bottom of the control mechanism, and the output end of the motor is connected to the first gear, and is used to drive the mounting seat to rotate and drive the base to rotate.

[0006] The output end of the motor extends into the interior of the mounting base and is connected to the first gear, capable of driving the base to rotate horizontally; the second gear on the control crossbar meshes with the first gear on the mounting base, so that while the first gear drives the mounting base to rotate under the drive of the motor, the second gear drives the control crossbar to rotate vertically, thereby adjusting the pitching angle of the base and the shooting angle of the photographic device. The motor is combined with the meshing transmission of the double gears, and the linkage of the control crossbar and the adjustment column is combined to realize the compound movement of the pitching angle adjustment and horizontal rotation of the base, so that the photographic device can be compensated for tilting with the ground and the stability of the photographic device on the base can be maintained. In addition, the base is rigidly connected to the adjustment column, stably carrying the photographic device and avoiding the nodding phenomenon of the traditional ball head pan-tilt head.

[0007] In some embodiments, a floating mechanism is provided between the mounting base and the control crossbar, including a universal base assembly and a swing base assembly, which are respectively arranged at both ends of the control crossbar and are used for meshing or separating the first gear on the mounting base and the second gear at one end of the control crossbar; First through grooves and second through grooves are respectively formed on two side surfaces of the mounting base, the universal base assembly at one end of the control crossbar is installed in the first through groove through a lifting assembly, and the swing base assembly at the other end is installed in the second through groove through a lifting assembly.

[0008] In some embodiments, the second gear is a bevel gear, with its small end facing the adjustment column and its large end facing the first through groove.

[0009] Since the second gear is a bevel gear and its small end faces the adjustment column, there is a distance between the control crossbar and the first gear, avoiding the situation of mutual interference between the control crossbar and the first gear when the control crossbar rotates in the mounting base, and ensuring the stability when adjusting the photographic device on the base.

[0010] In some embodiments, the universal base assembly includes a first ball seat, a second ball seat and a universal ball. One end of the first ball seat is installed on the control crossbar, and the other end is rotatably connected to the second ball seat through the universal ball; A ball groove for the universal ball to be embedded is formed at one end of the second ball seat close to the first ball seat, and the other end is installed in the first through groove through a lifting assembly.

[0011] In some embodiments, the swing base assembly includes a swing ball and a connecting column. One end of the connecting column is installed on the control crossbar, and the other end is connected to the swing ball. The swing ball is installed in the second through groove through a lifting assembly.

[0012] The arrangement of the universal base assembly and the swing base assembly is conducive to keeping the control crossbar floating with respect to the mounting base, avoiding direct contact between the control crossbar and the mounting base, preventing the control crossbar from wearing quickly, and enabling the control crossbar to have good stability and flexibility in the mounting base.

[0013] In some embodiments, the lifting assembly includes a lifting ring and a threaded connector sleeved outside the second ball seat and the swinging ball. A limiting seat is provided outside the lifting ring. Threaded holes communicating with the first through groove and the second through groove are respectively formed at the top of both side surfaces of the mounting seat. The threaded connector is connected to the limiting seat through the threaded hole; a lifting cover is installed at the top end of the threaded connector.

[0014] The universal joint assembly and the swinging seat assembly at both ends of the control crossbar are respectively installed in the first through groove and the second through groove through the lifting assembly. Therefore, under the action of the floating mechanism, the control crossbar can cooperate with the lifting assembly to adjust the control crossbar up and down in the mounting seat, so that the second gear meshes with or disengages from the first gear.

[0015] The two groups of lifting assemblies can independently adjust the control crossbar and the floating mechanism in the mounting seat, can change the angle of the control crossbar in the mounting seat as needed, and improve the adaptability of the control crossbar in the mounting seat; the control crossbar and the mounting seat remain floating under the action of the floating mechanism, avoiding mutual interference during the adjustment process with the lifting assembly, ensuring that the control crossbar can still maintain stable adjustment after adjustment, and improving the instant response ability of the control crossbar in the mounting seat.

[0016] In some embodiments, one end of the swinging ball away from the control crossbar is connected with a steering assembly through an adapter seat, which is used to control the pitch angle of the base independently when the first gear and the second gear are disengaged; The steering assembly includes a positioning ring plate, a positioning plate and a centering screw. The positioning ring plate is of an O-shaped structure and is installed in the first through groove; the positioning plate is installed on the adapter seat, and a limiting assembly is provided between the positioning ring plate and the positioning ring plate; threaded grooves are provided on both the positioning plate and the adapter seat for screwing in the centering screw to adjust the position of the positioning plate; A following assembly is provided between the centering screw and the limiting assembly.

[0017] Under the action of the positioning ring plate, the positioning plate can be stably connected with the adapter seat in the through groove, so that the rotation of the positioning plate drives the floating mechanism and the control crossbar to rotate in the mounting seat, and the control crossbar and the mounting seat can be adjusted independently or simultaneously, improving the flexibility of the mobile gimbal adjustment.

[0018] In some embodiments, the limiting assembly includes a pin column on the outer edge of the positioning plate and a plurality of abutting blocks; The plurality of abutting blocks are annularly arranged on the outer edge of the positioning plate, and a plug-in groove is formed between adjacent abutting blocks; a plurality of positioning grooves communicating with the first through groove are formed on the outer side of the positioning ring plate, and a limiting groove is formed between the positioning groove and the first through groove; The pin column is inserted and connected in the plug-in groove and the positioning groove.

[0019] In some embodiments, a bump seat is provided on each of the abutting blocks for manually rotating the positioning plate.

[0020] An L-shaped structure is formed by the combination of the abutting block and the bump seat, and the bump seat protrudes on the positioning plate. Therefore, the bump seat can stably fit with the hand of the photographer to ensure the stable rotation of the positioning plate.

[0021] In some embodiments, the following component includes a support base, a following disk, a following block and a limiting block. The support base and the following disk are sleeved on the centering screw rod. The following block is installed on the pin column, and the support base is connected to the pin column through the limiting block; The following block abuts against the outer edge of the following disk, and the inclination angles of the contact surfaces of the following disk and the following block are coupled; A chute is opened on one side of the limiting block close to the following block. A centering rod is arranged in the chute, and a centering slider is resetably sleeved on the centering rod. The centering slider is fixedly connected to the pin column.

[0022] When the control cross column is independently adjusted in the mounting seat, the pin column and the following component can form a locking structure to ensure the stability of the control cross column in the mounting seat.

[0023] In a second aspect, the present invention provides a photographic equipment support, including a tripod and the dual panoramic cloud platform as described in the first aspect. The motor at the bottom of the dual panoramic cloud platform is installed at the top of the tripod.

[0024] Beneficial effects:

[0025] 1. The setting of the control mechanism, the base and the tripod can not only achieve the tilt compensation of the photographic equipment on the tripod and the base to ensure the stability of the picture of the photographic equipment on the tripod, but also achieve the change of the pitching angle of the moving cloud platform while the base rotates on the tripod, improving the adjustment flexibility of the photographic equipment on the moving cloud platform and the tripod;

[0026] 2. The setting of the control cross column, the mounting seat and the floating mechanism can achieve the floating of the control cross column in the mounting seat, avoid the direct contact between the control cross column and the mounting seat, prevent the rapid wear of the control cross column, and enable the control cross column to maintain stable adjustment in the mounting seat, further improving the stability of the photographic equipment;

[0027] 3. The setting of the control cross column, the universal seat component, the swing seat component and the lifting component can adjust the horizontal angle of the control cross column in the mounting seat, realize the independent adjustment of the control cross column when the second gear is separated from the first gear, and improve the adaptability of the control cross column in the mounting seat;

[0028] 4. The settings of the control crossbar, steering assembly, and floating mechanism enable independent adjustment of the control crossbar, second ball seat, and connecting column within the mounting base, changing the pitch angle of the base, enhancing the instant response ability of the control crossbar within the mounting base, and increasing the flexibility of use.

[0029] 5. The settings of the following component, control crossbar, lifting component, and steering component form a locking structure when the control crossbar is independently adjusted within the mounting base, ensuring sufficient stability of the control crossbar within the mounting base, facilitating independent or simultaneous adjustment between the control crossbar and the mounting base, and further enhancing the flexibility of the tripod and mobile gimbal when used with a photographic device.

Therefore, other examples of the exemplary embodiments may also include different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0049] Embodiment 1:

[0050] As Figure 1 , Figure 2 and Figure 6 shown, this embodiment provides a dual panoramic pan-tilt head, including a base 11, a servo motor 12, and a control mechanism 2. The base 11 is used to carry a photographic device.

[0051] The control mechanism 2 includes a mounting base 21, a control cross bar 25, and an adjustment column 23. The mounting base 21 has a U-shaped structure, and a first gear 22 is mounted on the bottom surface; as Figure 5 shown, one end of the control cross bar 25 is sleeved with a second gear 24 meshing with the first gear 22 and is rotatably mounted inside the mounting base 21; one end of the adjustment column 23 is mounted at the outer center of the control cross bar 25, and the other end is fixedly connected to the base 11; it is used to adjust the pitching angle of the base 11. The servo motor 12 is mounted at the bottom of the control mechanism 2, and the output end of the servo motor 12 is connected to the first gear 22, which is used to drive the mounting base 21 to rotate and drive the base 11 to rotate.

[0052] As Figure 3 , Figures 6 to 8 shown, a floating mechanism 3 is provided between the mounting base 21 and the control cross bar 25, including a universal joint assembly and a swing seat assembly, which are respectively arranged at both ends of the control cross bar 25 and are used to engage or disengage the first gear 22 on the mounting base 21 and the second gear 24 at one end of the control cross bar 25.

[0053] As Figure 9 shown, first through slots 381 and second through slots 382 are respectively formed on two side surfaces of the mounting base 21. The universal joint assembly at one end of the control cross bar 25 is mounted in the first through slot 381 through a lifting assembly 4, and the swing seat assembly at the other end is mounted in the second through slot 382 through the lifting assembly 4.

[0054] In this embodiment, the second gear 24 is a bevel gear, with its small end facing the adjusting column 23 and its large end facing the first through groove 381.

[0055] As Figure 8 shown, the gimbal base assembly includes a first ball seat 31, a second ball seat 34 and a gimbal ball 32. One end of the first ball seat 31 is mounted on the control cross column 25, and the other end is rotatably connected to the second ball seat 34 through the gimbal ball 32. A ball groove 33 for the gimbal ball 32 to be embedded is formed at one end of the second ball seat 34 close to the first ball seat 31, and the other end is mounted in the first through groove 381 through the lifting assembly 4.

[0056] As Figure 7 shown, the swing seat assembly includes a swing ball 36 and a connecting column 35. One end of the connecting column 35 is mounted on the control cross column 25, and the other end is connected to the swing ball 36. The swing ball 36 is mounted in the second through groove 382 through the lifting assembly 4.

[0057] During use, the dual panoramic pan-tilt head is mounted on the tripod 1. Place the tripod 1. When the base 11 and the photographic equipment are inclined to the ground, the first gear 22 is driven by the servo motor 12 to rotate in the mounting seat 21, pushing the mounting seat 21 to rotate on the tripod 1, so that the rotation of the mounting seat 21 drives the base 11 to rotate and adjust on the tripod 1. At this time, the first gear 22 rotates and meshes with the second gear 24 to drive the control cross column 25 to rotate in the mounting seat 21. At this time, the rotation of the control cross column 25 drives the first ball seats 31 and the connecting columns 35 at both ends to rotate simultaneously, and the rotation of the connecting column 35 drives the swing ball 36 to rotate in the lifting ring 41. The rotation of the first ball seat 31 drives the gimbal ball 32 to rotate in the ball groove 33. Thus, the rotation of the control cross column 25 drives the adjusting column 23 to rotate simultaneously in the mounting seat 21, and the base 11 adjusts its pitch angle while rotating. At the same time, the angle adjustment of the base 11 drives the inclination angle between the photographic equipment and the ground to be adjusted simultaneously, which can realize the tilt compensation between the tripod 1 and the photographic equipment on the base 11 and the ground, and there is no need to readjust the tripod 1. In addition, the rotation adjustment of the base 11 can also increase the shooting range of the photographic equipment.

[0058] Embodiment Two:

[0059] On the basis of Embodiment One, this embodiment optimizes the structure of the dual panoramic pan-tilt head, so that the pitch angles of the control cross column 25 and the adjusting column 23 can still be adjusted when the first gear 22 is separated from the second gear 24.

[0060] As Figures 8 to 10As shown, the lifting assembly 4 includes a lifting ring 41 and a threaded post 43 sleeved outside the second ball seat 34 and the swing ball 36. A limit seat 42 is provided outside the lifting ring 41. Threaded holes 45 communicating with the first through groove 381 and the second through groove 382 are respectively opened at the top of both side surfaces of the mounting seat 21. The threaded post 43 is connected to the limit seat 42 through the threaded hole 45; a lifting cover 44 is installed at the top end of the threaded post 43.

[0061] Further, as Figure 4 , Figure 12 shown, one end of the swing ball 36 away from the control cross post 25 is connected with a steering assembly 5 through an adapter seat 37, which is used to independently adjust the pitching angle of the base 11 by the control cross post 25 when the first gear 22 and the second gear 24 are separated.

[0062] The steering assembly 5 includes a positioning ring plate 51, a positioning plate 52 and a centering screw 57. The positioning ring plate 51 is of an O-shaped structure and is installed in the first through groove 381; the positioning plate 52 is installed on the adapter seat 37, and a limiting assembly is provided between the positioning ring plate 51 and the positioning ring plate 51; threaded grooves 58 are provided on both the positioning plate 52 and the adapter seat 37 for screwing in the centering screw 57 to adjust the position of the positioning plate 52; a following assembly 6 is provided between the centering screw 57 and the limiting assembly.

[0063] The limiting assembly includes a pin post 56 and a plurality of abutting blocks 53 on the outer edge of the positioning plate 52; the plurality of abutting blocks 53 are annularly arranged on the outer edge of the positioning plate 52, and a plugging groove 54 is formed between adjacent abutting blocks 53; a plurality of positioning grooves 55 communicating with the first through groove 381 are opened on the outer side of the positioning ring plate 51, and a limiting groove 39 is formed between the positioning groove 55 and the first through groove 381; the pin post 56 is plugged and connected in the plugging groove 54 and the positioning groove 55.

[0064] As Figure 14 shown, a convex block seat 59 is provided on each of the abutting blocks 53 for manually rotating the positioning plate 52.

[0065] During use, when the first gear 22 is separated from the second gear 24 and the base 11 needs to be further adjusted, the lifting cover 44 is rotated to drive the threaded column 43 to rotate, and the threaded column 43 is screwed together with the threaded hole 45 to move upward along the threaded hole 45 and the first through groove 381 and the second through groove 382. At this time, the upward movement of the threaded column 43 drives the lifting ring 41 to move upward along the first through groove 381 and the second through groove 382. The upward movement of the lifting ring 41 drives the swinging ball 36, the connecting column 35 and the connecting seat 37 to move upward at the same time. The upward movement of the connecting seat 37 drives the positioning plate 52 and the centering screw 57 to move upward along one side of the positioning ring plate 51. The movement of the centering screw 57 drives the follower component 6 to move, so that the pin column 56 moves upward along the first through groove 381 and the limiting groove 39 between the positioning ring plate 51. As the connecting column 35 moves, it drives one end of the control cross column 25 to move upward, and the control cross column 25 moves upward, driving the first ball seat 31 and the universal ball 32 to move, and then the universal ball 32 moves along the ball groove 33, which is used to adjust the control cross column 25 to maintain a horizontal angle in the mounting seat 21. The second gear 24 is disconnected from the first gear 22 when the control cross column 25 is lifted, and the protrusion seat 59 is moved to drive the resistance block 53 and the positioning plate 52 to rotate. The rotation of the positioning plate 52 drives the swing ball 36, the connecting column 35 and the connecting seat 37 to rotate, so that the control cross column 25 and the adjustment column 23 can independently adjust the pitch angle in the mounting seat 21.

[0066] Embodiment three:

[0067] Based on the second embodiment, the present embodiment further optimizes the structure of the dual panoramic head, so that after the first gear 22 is separated from the second gear 24, the control cross column 25 and the adjustment column 23 are adjusted to a suitable pitch angle and can remain locked.

[0068] like Figure 11 , Figures 13 to 15 As shown, the following assembly 6 includes a supporting seat 63, a following plate 62, a following block 61 and a limiting block 64. The supporting seat 63 and the following plate 62 are sleeved on the centering screw 57, the following block 61 is installed on the latch column 56, and the supporting seat 63 is connected to the latch column 56 through the limiting block 64; the following block 61 abuts against the outer edge of the following plate 62, and the contact surfaces of the following plate 62 and the following block 61 are coupled at an inclined angle.

[0069] A centering slot 68 is provided on one side of the limiting block 64 close to the following block 61 . A centering rod 65 is provided in the centering slot 68 . A centering slider 67 is resettably mounted on the centering rod 65 . The centering slider 67 is fixedly connected to the latch column 56 .

[0070] In this embodiment, Figure 15 As shown, the centering rod 65 is cylindrical and the top is concave inwards.

[0071] During use, press the positioning plate 52 to make it contact with one side of the positioning ring plate 51, and rotate the centering screw 57 to engage it with the thread groove 58, so that the centering screw 57 moves deeper into the thread groove 58.

[0072] At this time, when the follower disc 62 rotates and moves with the centering screw 57, the outer slope of the follower disc 62 cooperates with the outer slope of the follower block 61, so that the follower disc 62 moves and approaches the positioning plate 52.

[0073] When the follower disc 62 moves, there is a gap between the follower disc 62 and the follower block 61. At this time, the extrusion force of the return spring 66 between the centering slider 67 and the centering chute 68 becomes smaller, and the elasticity of the return spring 66 itself gives a thrust to one side of the centering slider 67, so that the centering slider 67 is pushed to move along the centering rod 65 in the direction close to the follower disc. The movement of the centering slider 67 drives the follower block 61 to move simultaneously, so that the follower block 61 and the follower disc 62 always maintain slope cooperation. The movement of the follower block 61 drives the pin column 56 to move along the limit groove 39 into the plug-in groove 54 and the positioning groove 55. Then, the pin column 56 forms a clamping contact with the contact block 53 and the positioning ring plate 51 in the plug-in groove 54 and the positioning groove 55, and the positioning plate 52 and the positioning ring plate 51 are locked.

[0074] Embodiment 4:

[0075] This embodiment provides a photographic equipment support, including a tripod 1 and the dual panoramic cloud platform described in any one of Embodiments 1 to 3. The servo motor 12 at the bottom of the dual panoramic cloud platform is installed in the middle of the top of the tripod 1.
