Description

Technical Field

[0001] This utility model relates to the field of camera gimbal technology, specifically to an automatic rotating gimbal structure. Background Technology

[0002] A pan-tilt head is a support platform for shooting equipment, mainly used to mount and fix mobile phones, cameras, and camcorders. Based on the usage environment, they are divided into indoor and outdoor types, encompassing both fixed and motorized pan-tilt heads. Motorized models all support horizontal scanning, with a horizontal rotation range of 0° to 35° and a pitch angle of -35° to 35°. The pan-tilt head employs a horizontal and vertical limit bolt design, using microswitches to achieve the limit function; when the rotation angle reaches the preset value, the power is cut off to stop rotation.

[0003] Nowadays, in order to expand the field of view, cameras are placed at high positions. Most cameras have a pan-tilt head at the bottom that is manually rotated. This process makes it inconvenient to adjust the camera angle and greatly endangers the personal safety of the staff, resulting in poor performance.

[0004] Therefore, there is an urgent need to design an automatic rotating gimbal structure, which consists of an X-axis rotation mechanism, a Y-axis rotation mechanism, and a circumferential rotation mechanism. The camera is installed in the circumferential rotation mechanism. These three mechanisms provide the camera with three degrees of freedom. All three mechanisms are controlled by motors, thus enabling automatic rotation. Utility Model Content

[0015] In this embodiment, the X-axis rotation mechanism 2 includes: an X-axis frame 21, a first motor 22, a first driving gear 23, and a first supporting gear 24. The X-axis frame 21 is rotatably mounted in the main frame 1. The first motor 22 is fixedly mounted on the inner wall of the main frame 1.

The outer ring frame 41 is fixedly installed on the side wall of the Y-axis frame 31. The inner ring frame 42 is slidably fitted into the outer ring frame 41.

[0018] Working principle:

[0019] Because of the main frame 1, the X-axis rotation mechanism 2 is rotatably mounted within the main frame 1, the Y-axis rotation mechanism 3 is rotatably mounted within the X-axis frame 21, and the circumferential rotation mechanism 4 is mounted at the bottom of the Y-axis frame 31. The camera equipment can be mounted within the circumferential rotation mechanism 4. When the X-axis rotation mechanism 2 moves, it drives the Y-axis rotation mechanism 3 and the circumferential rotation mechanism 4 to rotate in the X-axis direction. When the Y-axis rotation mechanism 3 moves, it drives the circumferential rotation mechanism 4 to rotate in the Y-axis direction. And when the circumferential rotation mechanism 4 moves, it drives the camera equipment to rotate in the circumferential plane.

[0020] The X-axis rotation mechanism 2 is composed of a first motor 22, a first driving gear 23, and a first supporting gear 24. When the first motor 22 starts, it drives the first driving gear 23 to rotate. The first supporting gear 24 meshes with the first driving gear 23 and is mounted on the X-axis frame 21. As the first driving gear 23 rotates, it drives the X-axis frame 21 to rotate on the X-axis.

[0021] The Y-axis rotation mechanism 3 is composed of a second motor 32, a second driving gear 33, and a second supporting gear 34. When the second motor 32 starts, it drives the second driving gear 33 to rotate. The second supporting gear 34 meshes with the second driving gear 33 and is mounted on the inner wall of the Y-axis frame 31. As the second driving gear 33 rotates, it drives the Y-axis frame 31 to rotate on the Y-axis.

[0022] The circumferential rotation mechanism 4 consists of an outer ring frame 41, an inner ring frame 42, a third motor 43, a third driving gear 44, and a third supporting gear 45. When the third motor 43 starts, it drives the third driving gear 44 to rotate. The third supporting gear 45 meshes with the third driving gear 44 and is mounted on the top surface of the inner ring frame 42. As the third driving gear 44 rotates, it drives the inner ring frame 42 to rotate circumferentially.

[0023] This utility model provides an automatic rotating gimbal structure, which divides the gimbal into an X-axis rotation mechanism, a Y-axis rotation mechanism, and a circumferential rotation mechanism 4. The camera device is installed in the circumferential rotation mechanism 4. The X-axis rotation mechanism, Y-axis rotation mechanism, and circumferential rotation mechanism 4 enable the camera device to obtain three degrees of freedom. All three mechanisms are controlled by motors, thereby achieving the function of automatic rotation.
