InactiveCN101958064AAbsorb or dampen shock energySoft returnCosmonautic condition simulationsSimulatorsSteering angleSteering wheel
The invention discloses a self-aligning steering wheel simulation device for an automobile driving training apparatus. The simulation device has the structure that: a steering wheel is fixed with a steering shaft; the steering shaft is connected with a screw rod by a reduction gearbox; a screw rod nut and the screw rod form a transmission pair; the screw rod is supported by a frame; two springs are respectively fixed on the inner wall of the frame; the screw rod nut is provided with a connecting rod; two ends of the connecting rod are fixed at a central position of the two springs respectively; one end of the connecting rod is connected with a displacement sensor to transmit a steering angle of the steering wheel to a signal processing system of the automobile driving training apparatus in real time; simultaneously the springs are compressed and stretched to accurately position the steering angle of the steering wheel and a position of a wheel. After steering force is removed, the steering wheel is automatically and steadily aligned without a rebound phenomenon. When a trainee operates the device, the steering wheel generates actual force feeling feedback with the change of a rotation angle. Simultaneously, the device has the advantages of simple installation, convenient maintenance, high environmental protection performance and higher practical value.

Refrigerator and drawer assembly of refrigerator

The invention relates to a refrigerator and a drawer assembly of the refrigerator. The drawer assembly includes a drawer. The left and right sides of the drawer assembly are provided with an upper guiding strip and a lower guiding strip. Two supporting assemblies are fixed to the left and right sides of a storage compartment separately. Each supporting assembly includes a supporting frame providedwith an upper sliding groove and a lower sliding groove. Each lower sliding groove is provided with a front vertical section, a horizontal section and a back vertical section. A connecting piece includes a sliding part and a rotation part which are mounted in the upper sliding grooves. The rotation part is provided with a front guiding column penetrating into the lower sliding groove. The front guiding column is provided with a block stopping part. The end parts of the block stopping part and the end part of the rotation part are separately clamped on the left and right sides of the lower sliding grooves. An elastic component applies an elastic force to the connecting piece. When the drawer is closed, the upper guiding strip moves backwards and downwards presses the front guiding column to make the front guiding column be separated from the front vertical section to enter the horizontal section and abut against the front of the lower guiding strip, so that the drawer can be pushed backwards under action of the elastic force. When the drawer moves frontwards, the lower guiding strip pushes the front guiding column frontwards to make the front guiding column be clamped into the front vertical section. When the drawer is in an abnormal condition and moves backwards, the lower guiding strip moves backwards and downwards presses the front guiding column to make the front guiding column enter the back vertical section to make the lower guiding strip go cross the front guiding column, so that the front guiding column is located in front of the lower guiding strip again.
