The invention discloses an unmanned plane undercarriage
control system which comprises a control mechanism, a drive part, a control part, a sensor part, an undercarriage arm and a
damper rod, wherein, the control mechanism has a worm wheel and worm structure, one end of the rocker of the control mechanism is fixedly connected with the worm wheel and the other end is connected with one end of the
damper rod, the other end of the
damper rod is connected with the upper part of the undercarriage arm through a pin roll, one end of the worm is connected with the drive part, the sensor part is arranged in the upper limit hole and the
lower limit hole of the control mechanism, the control mechanism is fixedly arranged on the load-carrying structure of the plane body, the upper end of the undercarriage arm is connected with the plane body through a load-carrying rotating shaft on the plane body and the lower end of the undercarriage arm is connected with the front wheel of the plane, the control part is arranged on the
avionics frame of the plane and respectively abutted with the drive part and the drive part through cables. The invention uses the simple mechanical structure, the simple
electric drive apparatus and the spring-type damper rod and needs no supplementary structures or power-assisted devices for support, having a small volume and occupying little space. The invention can realize locking of the undercarriage up and down stations under the coordination of the worm wheel and worm structure, the
crank link mechanism and the brushless motor static
brake resistance.
