Description

Technical Field

[0001] This utility model relates to the field of PT gimbal transmission mechanism, specifically a PT gimbal transmission mechanism. Background Technology

[0002] Currently, intelligent manufacturing technology has been gradually applied to various industries. The rapid development of artificial intelligence technology has made PTZ camera technology more mature. Some PTZ cameras use brushless DC motors to enable the PTZ to operate at a faster speed when horizontally and in pitch, which greatly expands the range of motion of the PTZ camera and improves the quality of motion images.

[0003] Currently, PTZ cameras on the market are used for monitoring living rooms and support motion tracking. Some games may also require cameras to capture player movements, in which case the PTZ needs to provide a flexible viewing angle and panoramic tracking. This requires the PTZ to rotate 360°. If no protective measures are added during the rotation, the cables may become tangled or damaged over time.

[0004] If the aforementioned 360° rotating gimbal uses a traditional method where the terminal wires follow the rotation of the transmission structure, the terminal wires in contact with the rotating structure are prone to breakage and damage after a long period of time. The terminal wires rotating with the structure will also become tangled in one direction, preventing continuous rotation. Furthermore, if there are many terminal wires, they are also prone to tangling, leading to unstable power supply and affecting signal transmission. It will also be difficult to quickly identify the problem if a wire breaks occur. Stability is also required during gimbal rotation. If the rotating part of the gimbal is too long, tilting and shaking will affect the performance and degrade the user experience. Utility Model Content

[0005] The purpose of this invention is to provide a PT gimbal transmission mechanism to solve the problems mentioned in the background art, which involve the traditional method of using terminal wires to follow the rotation of the transmission structure. These problems include the terminal wires in contact with the rotating structure being prone to breakage and damage after prolonged use; the terminal wires rotating with the structure becoming tangled in one direction, preventing continuous rotation; and the large number of terminal wires also easily becoming tangled, leading to unstable power supply, affecting signal transmission, and making it difficult to quickly identify problems when wire breaks occur. Furthermore, the gimbal requires a certain degree of stability during rotation. Excessive length of the rotating part of the gimbal, tilting, and shaking can all affect the performance and degrade the user experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PT gimbal transmission mechanism, comprising a conductive slip ring, a rotating shaft, a sleeve gear, a base, and a gearbox. The gearbox is mounted on the base. The bottom end of the rotating shaft is connected to a connecting shaft. The connecting shaft is rotatably connected to the base, and the sleeve gear is fixed to the connecting shaft by bolts. The sleeve gear is connected to a gear transmission mechanism inside the gearbox. The conductive slip ring is provided inside the rotating shaft.

[0007] In a further embodiment, the rotating shaft is provided with a stepped hole, and a conductive slip ring is fitted into the stepped hole.

[0008] In a further embodiment, the gearbox has a gearbox cover on top, and a motor is provided on one side of the top of the gearbox cover.

[0009] In a further embodiment, the gearbox is internally provided with a driving double gear set, a first transmission double gear set, a second transmission double gear set, a third transmission double gear set, and a fourth transmission double gear set that are mutually controlled by gear transmission. The driving double gear set is connected to the output shaft of the motor, and the fourth transmission double gear set is connected to the sleeve gear transmission.

[0010] In a further embodiment, the base is provided with support feet at the bottom corners, and the ends of the support feet are provided with detachable plugs.

[0011] In a further embodiment, a bushing is provided on the outer side of the rotating shaft, and bearings are provided at both ends of the bushing, and the rotating shaft is rotatably connected to the bearings.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through a dual-bearing rotating structure and the use of conductive slip rings, not only satisfies the functions of transmitting power and control signals from the fixed device to the rotating device, enabling the pan-tilt unit to rotate continuously in all directions horizontally, but also effectively protects the terminal wires and extends their service life. This utility model uses a dual-bearing structure to support rotation, which can reduce the radial clearance of the rotating structure; by adding a wave-shaped spring pad, the axial clearance of the rotating part is eliminated, avoiding the "shaking" phenomenon of the image; the dual-bearing structure combined with the wave-shaped spring pad reduces the overall swing of the gimbal, improves the rotation accuracy, and enhances the stability of the gimbal rotation.
