The invention relates to an active air-inlet grille with external blades controlled by hinge mechanisms to turn over and a vehicle. The active air-inlet grille with the hinge mechanism controlling the external blade to turn over comprises a frame AD, a blade CF, the hinge mechanism and a motor, the frame AD is connected with the blade CF through the hinge mechanism, the motor is arranged on the hinge mechanism, and the hinge mechanism is used for driving the blade CF to turn over. Compared with the prior art, the active air inlet grille is arranged through a hinge mechanism under the condition that the front end space is not met, a movement mechanism moves backwards, force transmission points of the blades and the connecting rods are designed to be close to the middle positions of the blades or relatively uniform positions at the two ends of the blades, the torque is reduced, and the blades can be turned over normally; and the system development cost is reduced.

The present application relates to a kind of rocker gear force loading dummy, belong to the technical field of aircraft structure strength statics / fatigue test.A kind of rocker gear dummy, its key transmission point coordinate, constraint mode are consistent with real landing gear, structural strength meets the whole cycle requirement of whole machine fatigue test, including main pillar dummy, lower rocker arm dummy, upper arm dummy, main shaft dummy……, also include dummy wheel and fixed support;Dummy wheel includes wheel axle, loading plate, one end of wheel axle is polygonal wheel axle anti-rotation fit section, for transmitting landing gear touch point X direction load, wheel axle anti-rotation fit section is adapted to be opened on lower rocker arm dummy on mounting hole, and with mounting hole insertion, loading plate is set on the other end of wheel axle, and a plurality of loading holes are opened on it;Fixed support is installed in the end of lower rocker arm dummy.The present application has the following advantages: meet the whole cycle of whole machine fatigue test;Can save cost;Realize the functional requirement of rocker gear;Fixed support supports aircraft in static state.

The utility model belongs to the field of disconnecting switches, and particularly relates to a transmission mechanism and a disconnecting switch, comprising a transmission assembly, the transmission assembly is connected between a lower connecting rod of an operating mechanism and a first main shaft and a second main shaft of a switch body, and the transmission assembly is configured to transmit the driving force of the operating mechanism to the first main shaft and the second main shaft of the switch body. The transmission assembly comprises a driving gear, an upper transmission gear, a lower transmission gear and a connecting rod, the driving gear is rotationally arranged on a mechanism frame of the operating mechanism and is in linkage fit with the lower connecting rod, the upper transmission gear and the lower transmission gear are arranged on a first main shaft and a second main shaft of the switch body in a linkage mode respectively, and the connecting rod is connected between the upper transmission gear and the lower transmission gear; the driving gear is meshed with the upper transmission gear; the transmission mechanism adopts a gear transmission structure design, so that the distance between the transmission point of the operating mechanism and the first main shaft of the switch body is effectively shortened, and the design requirement of miniaturization of the isolating switch can be met.
