Problems solved by technology
In order to achieve multi-angle shooting under remote control, video capture equipment such as cameras is usually installed on a two-degree-of-freedom pan-tilt. Class PTZs have relatively high requirements on the control part, and it is usually difficult to achieve a stable and constant swing speed of the camera. Therefore, using a simple mechanism and control circuit to realize the constant swing of the camera is an urgent problem to be solved at present.

Embodiment Construction
[0010] The invention relates to a cloud platform with two degrees of freedom. refer to figure 1 , figure 2 , the head mainly includes bracket 1, support plate 2, worm 3, worm gear 4, shaft I5, shaft II6, end cover 7, swing bracket 8, shaft III9, swing gear 11, transition gear 12, incomplete gear 13 , sector gear 14 and a motor as a power source. The camera head 10 is driven by a swing gear 11 . The worm 3 and the worm gear 4 form a reduction mechanism. The swing mechanism is mainly composed of a swing gear 11, a transition gear 12, an incomplete gear 13 and a sector gear 14. The swing gear 11 meshes with the transition gear 12, and the incomplete gear 13 and sector gear 14 are the same. Shaft, the motor drives the incomplete gear 13 and the sector gear 14 to rotate through the worm gear and worm, and the swing gear 11 is driven by the sector gear 14 and the incomplete gear 13 in turn to realize the camera head 10 swinging up and down. When the swing gear 11 is driven by t...

The invention relates to a two-degree-of-freedom platform, including a bracket, a motor and a speed reduction mechanism installed on the bracket, and the special feature is that the platform is provided with two swing mechanisms, and each swing mechanism realizes a back and forth swing in a plane , the two swings can be realized independently. The swing mechanism is mainly composed of a swing gear, a transition gear, an incomplete gear and a sector gear. This pan / tilt can realize the swing motion of the pan / tilt when the driving motor rotates in one direction, and the positioning is accurate. The swing range of the pan / tilt can be adjusted by changing the transmission ratio of the swing mechanism; the swing speed of the pan / tilt can be adjusted according to requirements The speed of the drive motor is achieved. Moreover, the cloud platform is simple in processing and low in cost, and can also be used in other occasions that require swinging, and has wide application value.
Description
technical field [0001] The invention relates to a two-degree-of-freedom platform, belonging to a controllable load platform, which can drive its load to rotate in two mutually perpendicular planes, and the rotation can be independent or simultaneous. Background technique [0002] With the continuous progress of society, the application range of image monitoring system is getting wider and wider, and it is widely used in banks, transportation, shopping malls, intelligent communities and other occasions. In order to realize multi-angle shooting under remote control, video capture devices such as cameras are usually installed on two-degree-of-freedom pan-tilts. Class PTZs have relatively high requirements on the control part, and it is usually difficult to achieve a stable swing speed of the camera. Therefore, using a simple mechanism and control circuit to realize the constant swing speed of the camera is an urgent problem to be solved at present. Contents of the invention ...
