Description

Technical Field

[0001] This application relates to the field of gimbal manufacturing technology, specifically an integrated high-precision gimbal structure. Background Technology

[0002] Gimbals are generally used in situations where both azimuth and pitch rotation are required. They are typically mounted on a tripod, such as in photography, videography, and stage lighting control. These applications do not have high requirements for technical specifications such as precision, speed, and acceleration / deceleration.

[0003] However, in some mobile applications, such as carrying laser obstacle clearing devices, astronomical telescopes, and radar tracking scanners in the field, the technical specifications of the gimbal generally prioritize high precision and heavy load capacity. Current tripods typically use a top-mounted design, with a 1 / 4 or 3 / 8 inch bolt at the top. A corresponding threaded hole is pre-drilled at the bottom of the load device. During use, the load device is screwed into the bolt on top of the gimbal, securing it from the bottom. Sometimes, a quick-release plate is used for easy adjustment between the gimbal and the load device. This structure, connected only by a single bolt at the bottom and transferring the load weight through multiple connections, generally suffers from low rigidity, susceptibility to deformation, and low stability, leading to issues with the precision of the load device. Summary of the Invention

[0004] The purpose of this application is to address the shortcomings of existing technologies by designing an integrated high-precision gimbal structure that uses a mounting ring on a tripod that is locked by locking bolts. This solves the problems of low rigidity, easy deformation, and low stability of existing gimbal structures, which lead to low precision of the load-bearing equipment.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] An integrated high-precision gimbal structure includes a tripod, a pitch adjustment module, an azimuth adjustment module, and a load platform. The tripod has a mounting ring at its top, with a circumferential angle between 180° and 360°. Each end of the annular opening on the outer circumference of the mounting ring has a connecting lug, which is locked together by locking bolts. The azimuth adjustment module has an annular protrusion between its upper and lower ends, with the outer diameter of the protrusion being larger than the outer diameter of the mounting ring. The lower end of the azimuth adjustment module is inserted axially into the mounting ring. The actuator of the azimuth adjustment module is fixedly connected to the pitch adjustment module, which in turn is fixedly connected to the load platform. The rotation axis of the actuator of the azimuth adjustment module is parallel to the axis of the mounting ring, while the rotation axis of the actuator of the pitch adjustment module is perpendicular to the axis of the mounting ring.

[0007] Preferably, the orientation adjustment module includes an orientation motor reduction module and a first housing. The annular protrusion is provided between the upper and lower ends of the first housing. The actuating end of the orientation motor reduction module faces upward. The orientation motor reduction module is fixedly disposed inside the first housing. The first housing is fixedly connected to the annular protrusion. The actuating end of the orientation motor reduction module passes through the first housing. The pitch adjustment module is fixedly connected to the actuating end of the orientation motor reduction module outside the first housing.

[0008] Preferably, the top of the outer circumferential surface of the first housing is provided with a radial protrusion, and the lower surface of the pitch adjustment module is provided with a directional limiting bolt that cooperates with the protrusion.

[0009] Preferably, the pitch adjustment module includes a pitch motor reduction module and a second housing. The second housing has openings at both ends. The lower surface of the second housing is fixedly connected to the actuation end of the azimuth adjustment module. The pitch motor reduction module is fixedly disposed inside the second housing. The actuation end of the pitch motor reduction module extends out of the second housing from one opening. A rear cover is provided at the other opening of the second housing.

[0010] Preferably, the lower surface of the load platform is provided with a first foot and a second foot, the first foot is fixedly connected to the execution end of the pitch motor reduction module, and the second foot is rotatably connected to the rear cover.

[0011] Preferably, the second housing is provided with a pitch limiting bolt that cooperates with the first support leg, and the pitch limiting bolt is located on the outer side wall of the second housing facing the first support leg.

[0012] Preferably, the upper surface of the second housing is arc-shaped, and the center of the virtual circle containing the arc is on the rotation axis of the execution end of the pitch motor reduction module. The distance from the outer top wall of the second housing to the rotation axis of the execution end of the pitch motor reduction module is less than the distance from the load platform to the rotation axis of the execution end of the pitch motor reduction module.

[0013] The beneficial effects of this application are:

[0014] This application proposes an integrated high-precision gimbal structure by setting a mounting ring on the tripod and locking it with locking bolts. This solves the problems of low rigidity, easy deformation, and low stability of existing gimbal structures, which lead to low accuracy of the load equipment. Attached Figure Description

[0021] like Figure 1-5 As shown, an integrated high-precision gimbal structure includes a tripod 1, a pitch adjustment module, an azimuth adjustment module, and a load platform 4. A mounting ring 16 is provided on the top of the tripod 1. The circumferential angle of the mounting ring 16 is between 180° and 360°. A connecting lug 5 is provided at each end of the annular opening on the outer circumference of the mounting ring 16. The two connecting lugs 5 are locked together by locking bolts 7. An annular protrusion 6 is provided between the upper and lower ends of the azimuth adjustment module. The outer diameter of the annular protrusion 6 is larger than the outer diameter of the mounting ring 16. The lower end of the azimuth adjustment module is inserted axially into the mounting ring 16. The actuator of the azimuth adjustment module is fixedly connected to the pitch adjustment module, and the actuator of the pitch adjustment module is fixedly connected to the load platform 4. The rotation axis of the actuator of the azimuth adjustment module is parallel to the axis of the mounting ring 16, and the rotation axis of the actuator of the pitch adjustment module is perpendicular to the axis of the mounting ring 16.

[0022] In this application, the pitch adjustment module adjusts the load platform 4 to rotate around a horizontal axis to achieve pitch adjustment, while the azimuth adjustment module allows the entire pitch adjustment module and the load platform 4 to rotate around a vertical axis to achieve north-south and east-west directional adjustment. The mounting ring 16 acts as a clamp, securing the azimuth adjustment module in conjunction with the locking bolt 7. The annular protrusion 6 ensures that when the lower end of the azimuth adjustment module is inserted axially into the mounting ring 16, the annular protrusion 6 will engage with the upper surface of the mounting ring 16, acting as a longitudinal movement limiter to prevent the azimuth adjustment module from falling, while also not affecting the rotation of the azimuth adjustment module around the axis of the mounting ring 16.

[0023] In a preferred embodiment, the orientation adjustment module includes an orientation motor reduction module 3 and a first housing 8. The annular protrusion 6 is provided between the upper and lower ends of the first housing 8. The actuating end of the orientation motor reduction module 3 faces upward. The orientation motor reduction module 3 is fixedly disposed inside the first housing 8. The first housing 8 is fixedly connected to the annular protrusion 6. The actuating end of the orientation motor reduction module 3 passes through the first housing 8. The pitch adjustment module is fixedly connected to the actuating end of the orientation motor reduction module 3 outside the first housing 8. With this configuration, the orientation motor reduction module 3 is protected by the first housing 8.

[0024] As a preferred embodiment, the top of the outer circumferential surface of the first housing 8 is provided with a radial protrusion 9, and the lower surface of the pitch adjustment module is provided with a directional limiting bolt 10 that cooperates with the protrusion 9. The protrusion 9 ensures that when the first housing 8 rotates, the directional limiting bolt 10 is blocked when it reaches the protrusion 9, thus providing a limiting function.

[0025] In a preferred embodiment, the pitch adjustment module includes a pitch motor reduction module 2 and a second housing 11. The second housing 11 has openings at both its left and right ends. The lower surface of the second housing 11 is fixedly connected to the actuating end of the azimuth adjustment module. The pitch motor reduction module 2 is fixedly disposed inside the second housing 11. The actuating end of the pitch motor reduction module 2 extends out of the second housing 11 from one opening. A rear cover 12 is provided at the other opening of the second housing 11. This configuration protects the pitch motor reduction module 2, while the rear cover 12 encapsulates the second housing 11.

[0026] As a preferred embodiment, the lower surface of the load platform 4 is provided with a first support leg 13 and a second support leg 14. The first support leg 13 is fixedly connected to the actuator of the pitch motor reduction module 2, and the second support leg 14 is rotatably connected to the rear cover 12. This arrangement makes the load platform 4 more stable during rotation. The second support leg 14 allows the rear cover 12 to not only enclose the second housing 11 but also rotatably connect to the second support leg 14, thereby ensuring the stability of the load platform 4.

[0027] As a preferred embodiment, the second housing 11 is provided with a pitch limiting bolt 15 that mates with the first support leg 13. The pitch limiting bolt 15 is located on the outer side wall of the second housing 11 facing the first support leg 13. By providing the pitch limiting bolt 15, when the first support leg 13 encounters the pitch limiting bolt 15 during rotation, it is stopped by the pitch limiting bolt 15, thereby limiting the rotation and preventing the load platform 4 from overturning under the drive of the pitch motor reduction module 2.

[0028] As a preferred embodiment, the upper surface of the second housing 11 is arc-shaped, and the center of the virtual circle containing the arc lies on the rotation axis of the actuator end of the pitch motor reduction module 2. The distance from the outer top wall of the second housing 11 to the rotation axis of the actuator end of the pitch motor reduction module 2 is less than the distance from the load platform 4 to the rotation axis of the actuator end of the pitch motor reduction module 2. The arc-shaped design prevents the upper surface of the second housing 11 from obstructing the rotation of the load platform 4.
