The embodiment of the utility model provides a concentric drive mechanism 1, as shown in fig. 1-3, concentric drive mechanism 1 includes mount pad 11, rotation driving component 12 and planetary gear transmission assembly 13, and wherein, planetary gear transmission assembly 13 includes sun gear 131, planet wheel 132 and is used for the rotation lid 133 of installation shooting equipment. The rotation driving component 12 is installed on the installation base 11, the sun gear 131 is installed on the rotation driving component 12, the planet gear 132 includes a first gear 1321 engaged with the sun gear 131, and a second gear 1322 coaxially disposed on a side of the first gear 1321 away from the rotation driving component 12, where the second gear 1322 is smaller in diameter than the first gear 1321. A groove 1331 is formed on the rotating cover 133, and a groove wall surrounding the groove 1331 is provided with a ring gear 1332 engaged with the second gear 1322.

Specifically, the rotation driving assembly 12 drives the sun gear 131 to rotate, so as to drive the first gear 1321 engaged with the sun gear 131 to rotate, because the second gear 1322 is coaxially disposed with the first gear 1321, the first gear 1321 drives the second gear 1322 to rotate when rotating, because the second gear 1322 is engaged with the gear ring 1332 disposed on the rotating cover 133, the second gear 1322 drives the rotating cover 133 to rotate when rotating, and finally the rotating cover 133 drives the shooting device mounted on the rotating cover 133 to rotate.

In the concentric transmission mechanism 1 provided in the present embodiment, the second gear 1322 coaxially disposed with the first gear 1321 is additionally disposed on the side of the first gear 1321 away from the rotary driving component 12, and the gear ring 1332 is disposed on the rotary cover 133 for mounting the shooting device, and the gear ring 1332 is engaged with the second gear 1322, specifically, since the diameter of the second gear 1322 additionally disposed in the present embodiment is smaller than that of the first gear 1321, compared with the conventional technical scheme in which the gear ring 1332 is engaged with the first gear 1321, the diameter of the gear ring 1332 in the present embodiment is much smaller, so that the concentric transmission mechanism 1 in the present embodiment has a smaller volume compared with the conventional technology, and thus, the volume of the pan-tilt head on which the concentric transmission mechanism 1 in the present embodiment is mounted can also be made smaller, and is more easily favored by consumers.

The utility model provides a planet wheel 132 quantity can lean on technical staff in the field to set to two, three etc. to adaptability, and this embodiment does not do the restriction here, and technical staff in the field can carry out the adaptability design to this.

Since the first gear 1321 and the second gear 1322 of the present embodiment rotate on their own axis rather than revolve around the rotational driving component 12, a corresponding structure must be provided to limit the rotation of the first gear 1321 and the second gear 1322 around the rotational driving component 12, and two embodiments are listed below for reference.

In one embodiment, as shown in fig. 1-3, the planetary gear assembly 13 further includes a rotating shaft 136, one end of the rotating shaft 136 is inserted into the mounting seat 11, and the first gear 1321 and the second gear 1322 are both mounted on the rotating shaft 136. The structure of this embodiment is comparatively simple, and required spare part is less, therefore manufacturing cost is lower.

In another embodiment, as shown in fig. 1-3, the planetary gear assembly 13 further includes a fixing base 134, a cover plate 135 and a rotating shaft 136. The fixing seat 134 is installed on the mounting seat 11 and located between the first gear 1321 and the mounting seat 11, and a first shaft hole 1341 is formed on a side of the fixing seat 134 facing away from the mounting seat 11. The cover plate 135 is installed on one side of the fixing base 134 far away from the mounting base 11, and a second shaft hole 1351 is formed in one side of the cover plate 135 facing the fixing base 134 and is coaxial with the first shaft hole 1341. Both ends of the rotating shaft 136 are respectively installed in the first shaft hole 1341 and the second shaft hole 1351, and the first gear 1321 and the second gear 1322 are both installed on the first shaft hole 1341.

In this embodiment, as shown in fig. 1-4, the fixing seat 134 and the cover plate 135 are oppositely disposed on two sides of the planet wheel 132, and two ends of the rotating shaft 136 are respectively disposed on the first shaft hole 1341 of the fixing seat 134 and the second shaft hole 1351 of the cover plate 135, so that the first shaft hole 1341 and the second shaft hole 1351 can respectively provide a constraining force for two ends of the rotating shaft 136, thereby effectively preventing the rotating shaft 136 from swaying along the radial direction thereof. The transmission between the first gear 1321 and the sun gear 131 is stabilized against slipping, and the transmission between the second gear 1322 and the ring gear 1332 is stabilized against slipping.

In an embodiment, as shown in fig. 1 to fig. 3, the planetary gear transmission further includes a screw (not shown), the cover plate 135 has a mounting through hole 1352, the fixing seat 134 has a first threaded hole 1342 coaxially disposed with the mounting through hole 1352, and the screw is sequentially inserted into the mounting through hole 1352 and the first threaded hole 1342, so as to mount the cover plate 135 on a side of the fixing seat 134 away from the mounting seat 11.

Specifically, the threaded connection structure is simple, the disassembly is convenient, and the connection is reliable and not easy to loosen. In this embodiment, the cover plate 135 can be fixed on the fixing seat 134 by a screw, so that the cover plate 135 cannot move relative to the fixing seat 134 along the axial direction of the rotating shaft 136, thereby preventing the rotating shaft 136 from shaking along the axial direction thereof, enabling the first gear 1321 and the sun gear 131 to stably transmit, and enabling the second gear 1322 and the gear ring 1332 to stably transmit.

In a particular embodiment, as shown in fig. 1-3, mounting through-hole 1352 is a stepped hole that includes a first hole segment (not shown) having a larger diameter and a second hole segment (not shown) having a smaller diameter. The diameter of the first hole segment is greater than the diameter of the head of the screw (not shown), and the screw is sequentially inserted into the first hole segment, the second hole segment and the first threaded hole 1342, so that the cover plate 135 is mounted on one side of the fixing base 134 away from the mounting base 11.

Through implementing this embodiment, when the screw is pegged graft in installation through-hole 1352, its head can not bulge apron 135, but can bury in first hole section, not only very pleasing to the eye, still is favorable to the miniaturization of planetary gear drive assembly 13.

In an embodiment, as shown in fig. 1 to 6, a receiving groove 1343 for receiving the first gear 1321 is disposed on a side of the fixing seat 134 facing away from the mounting seat 11, and the first axial hole 1341 is disposed at a groove bottom (not shown) of the receiving groove 1343; a rib 1334 is provided along the outer peripheral surface of the rotary cover 133 on the side of the rotary cover 133 close to the mounting seat 11, and the outer contour of the first gear 1321 is surrounded by the outer contour of the rib 1334 when viewed in the axial direction of the rotary shaft 136.

If the first gear 1321 is exposed, it is easy to hurt people when rotating, and the exposed first gear 1321 is easily affected by external environmental factors, so that the service life is short. The mounting seat 11 and the fixing seat 134 provided by the embodiment can be matched with each other, so that the first gear 1321 is shielded, the first gear 1321 can be prevented from hurting people, and the service life of the first gear 1321 can be prolonged.

In one embodiment, as shown in fig. 2, the first gear 1321 is integrally formed with the second gear 1322, which not only reduces the number of parts and simplifies the assembly process, but also reduces the number of mold opening. Therefore, the embodiment can reduce the production cost by reducing the mold opening cost and the assembly cost.

In an embodiment, as shown in fig. 1 to fig. 3, the concentric transmission mechanism 1 further includes a protective cover 14 fixedly connected to the mounting base 11, the protective cover 14 covers the planetary gear transmission assembly 13, and a mounting opening 141 is formed at a top of the protective cover 14 to expose a side of the rotating cover 133 away from the mounting base 11, so that the photographing apparatus can be mounted on the rotating cover 133 through the mounting opening 141.

The protective cover 14 of the present embodiment can cover the entire planetary gear assembly 13, so as to reduce the influence of the external environment on the planetary gear assembly 13, and to prolong the service life of the planetary gear assembly 13. In order not to affect the installation of the photographing device on the rotating cover 133, the installation opening 141 is opened at the top of the protective cover 14 in this embodiment, so that the photographing device can be installed on the rotating cover 133 through the installation opening 141, and since the installation opening 141 is only opened at the top of the protective cover 14, the outer peripheral surface of the rotating cover 133 is also covered by the protective cover 14 and is not exposed, so as to avoid the injury of the consumer due to the accidental touch.

In a specific embodiment, as shown in fig. 1 and 7, a second screw hole 1333 is provided on a side of the rotating cover 133 facing the mounting opening 141, and the second screw hole 1333 is used for being matched with an external screw to mount the photographing apparatus on the rotating cover 133.

In particular, the screw connection is simple in construction and the connection is very reliable.

In another embodiment, one of a slot (not shown) or a buckle (not shown) may be disposed on a side of the rotating cover 133 facing the mounting opening 141, and the camera is connected to the mounting structure through the other of the slot or the buckle.

Particularly, the buckle type connecting structure is simple, and the disassembly and the installation are very convenient.

In an embodiment, as shown in fig. 1 to 8, the concentric driving mechanism 1 further includes a pressing ring 15, the pressing ring 15 has a smooth inner circumferential surface 151 and an outer circumferential surface 152, the inner circumferential surface 151 of the pressing ring is sleeved on the outer circumferential surface (not shown) of the rotating cover 133, and the outer circumferential surface 152 of the pressing ring is connected to the inner circumferential surface (not shown) of the protecting cover 14.

Specifically, since the inner peripheral surface 151 of the pressing ring is fitted over the outer peripheral surface of the rotating cover 133 and the outer peripheral surface 152 of the pressing ring is in contact with the inner peripheral surface of the protecting cover 14, the pressing ring 15 of the present embodiment can close the gap between the rotating cover 133 and the protecting cover 14, so as to prevent dust in the external environment from adhering to the sun gear 131, the first gear 1321, the second gear 1322, or the ring gear 1332 through the gap, thereby achieving the technical effect of prolonging the service life of the planetary gear transmission assembly 13. Further, since both the pressing ring inner peripheral surface 151 and the pressing ring outer peripheral surface 152 are smooth, the friction force between the pressing ring 15 and the rotating cover 133 and the protective cover 14 is very small, and therefore the pressing ring 15 hardly affects the normal rotation of the rotating cover 133.

In one embodiment, the sun gear 131, the first gear 1321, the second gear 1322, the ring gear 1332, and the pressure ring 15 are all coated with grease (not shown).

Specifically, lubricating grease can increase the smooth degree of gear transmission, prevent gear wear, guarantee the high efficiency and the long-life of gear.
