Embodiment Construction

[0034] The present invention as figure 1 , 2 As shown, it includes a retractable mechanism 1, a driving part 2, a control part 3, a sensor part 4, a landing gear arm 5 and a shock absorber rod 6. The retractable mechanism 1 applies a driving force to the landing gear arm 5, so that the driving part 2 The rotational motion is converted into the retracting motion of the landing gear arm 5; the driving part 2 provides mechanical power for the retracting and retracting of the landing gear arm 5, and drives the retracting mechanism 1 to move; the control part 3 is based on the control amount of the flight control equipment and the feedback from the sensor part 4 Control the driving part 2 to perform the retracting action and the lowering action; the sensor part 4 reflects the state of the landing gear being retracted and lowered; the landing gear arm 5 connects the fuselage and the front wheel, and is dragged by the retracting mechanism 1 The shock absorber 6 is connected to the r...

Abstract

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.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle landing gear retractable system, in particular to a landing gear retractable system for a wheeled take-off and landing unmanned aircraft, which belongs to the technical field of unmanned aerial vehicles and can be applied to light aircraft of the same weight. Background technique [0002] Unmanned aerial vehicle, referred to as unmanned aerial vehicle (UAV); UAV is a new concept weapon equipment in rapid development. Its advantages have emerged in many local wars since the Vietnam War. UAVs have been used in tasks such as battlefield reconnaissance, surveillance, precise target positioning / indication, electronic countermeasures, communication relay, and combating ground "time-sensitive" targets. Very good performance. However, with the expansion of UAV applications, UAV flight platforms are developing in the direction of high altitude, high speed, long endurance, and stealth. [0003] At present, th...
