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.

This application relates to the field of automotive manufacturing technology and discloses a damping assembly for transmission connection with a first transmission point of a transmission assembly. The damping assembly includes a damping unit rotatable about a first rotation axis, the first rotation axis being arranged along a first direction. The damping unit includes a damping shell and a damping core, the damping core being located inside the damping shell, and the damping core interacting with the damping shell to reduce the rotational speed of the damping core. A moving unit is also included to drive the damping unit to move along the first direction to approach or move away from the first transmission point of the transmission assembly. During the movement of the damping unit, the interaction between the damping unit and the transmission assembly includes a first driving mode and a second driving mode. This application provides a damping assembly, transmission device, vehicle-mounted display terminal, and vehicle in which the damping unit is used in the first driving mode but not in the second driving mode.

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.

The utility model belongs to the technical field of automobile automatic doors, and provides an orthogonal nut swing driving mechanism which comprises a motor, a worm, a bevel gear and a lead screw assembly, the output of the motor is connected with the worm, the worm is meshed with the bevel gear, the driving mechanism further comprises a transmission nut and a transmission shaft tile, the lead screw assembly penetrates through the transmission nut, and the transmission shaft tile is meshed with the transmission nut. The transmission nut is connected and matched with the bevel gear and the transmission shaft tile. When the motor drives the worm to drive the bevel gear to rotate, the lead screw assembly and the transmission nut can stretch out and draw back and swing in the door under the action of the transmission shaft tile. The transmission device has the advantages that transmission points between the bevel gear and the transmission nut are circumferentially and evenly distributed, stress is even, two independent bearing bushes and transmission pins are not needed between the bevel gear and the transmission nut, production and machining are facilitated, the structure is more compact, transmission can be achieved only through one transmission bearing bush, and meanwhile limiting rotation can be conducted on the nut. A movable joint is limited at the tail of the lead screw and can adapt to various swing angles of different vehicle doors.

The present invention discloses a belt conveyor with adaptive tensioning force dynamic compensation, which relates to the technical field of belt conveyors. It includes a front fixed seat, two first hydraulic cylinders, two side frames, a front bracket and a rear fixed seat. The top end of the front bracket is internally connected to an upper rotating roller, and the top end of the rear fixed seat is internally connected to a lower rotating roller. Conveyor belts are sleeved on the outer sides of the upper and lower rotating rollers. An adjustment component is provided between the front fixed seat and the rear fixed seat. The bottoms of both sides of the front bracket are fixedly connected to fixed frames, and the fixed frames are internally slidably connected to a movable plate. A support spring is sleeved on the outer side of the slide rod, and support plates are fixedly connected on both sides of the two fixed frames. The belt conveyor with adaptive tensioning force dynamic compensation adjusts the angle of the conveyor belt and changes it according to the height difference of different transmission points, adapts to different working environments, and has a wide range of applications.
