Universal mechanism

Abstract

The invention provides a universal mechanism which comprises a first rotating motor, a second rotating motor, a third rotating motor, a second circular rotating disc and a universal head, wherein thesecond rotating motor, the third rotating motor, the second circular rotating disc and the universal head are driven by the first rotating motor to rotate as a whole; the third rotating motor, the second circular rotating disc and the universal head are driven by the second rotating motor to rotate as a whole; the second circular rotating disc is driven by the third rotating motor to rotate; the universal head is fixed on a side surface of the second circular rotating disc; and rotating axes of the first rotating motor, the second rotating motor and the third rotating motor are perpendicular to one another. By adopting the universal mechanism, a flying article is detected without a dead angle by an aircraft, blind areas can be effectively avoided, a real universal function of the universalmechanism is achieved, application of mechanical structures is reduced, an automatic control system can be widely used, the structure is simplified, the size and the weight are reduced, the control precision is improved, and the rotation direction of the universal head can be conveniently adjusted.

Description

technical field [0001] The invention relates to a universal mechanism. Background technique [0002] During the launch flight of the aircraft, it is necessary to use the gimbal mechanism to measure the direction of the aircraft or targets in other directions. In order to achieve the mission of aircraft flight, the universal mechanism is widely used in certain disposable aircraft, such as the steering gear rotation mechanism inside the aircraft, the target tracking mechanism, etc. These universal mechanisms can correctly reflect the flight rotation of the aircraft , and adjust the direction in real time according to the received signal. However, when these universal mechanisms are designed, they can usually only point to the front of the aircraft, and cannot detect flying objects in the rear or flying objects on the left and right sides, and cannot respond to other flying objects in the rear to the corresponding system. In addition, the traditional universal The mechanism u...

Problems solved by technology

However, when these universal mechanisms are designed, they can usually only point to the front of the aircraft, and cannot detect flying objects in the rear or flying objects on the left and right sides, and cannot respond to other flying objects in the rear to the corresponding system. In addition, the traditional universal The mechanism uses a mechanical structure, which is designed to have a large volume, complex structure, heavy weight, and many intermediate transmission links. It requires high matching accuracy and low response characteristics.
