Detailed Description
The present invention will be described in detail with reference to the accompanying drawings
As shown in fig. 1, a foot heating switch 8 in an aircraft environmental control system comprises a rotating shaft 1, a shell 2, an elastic washer 3, a pedal plate 4, a torque adjusting screw 5, a door plate 6 and a bushing 7, wherein the switch shell 2 adopts a cylindrical and hemispherical structure, the rotating door plate 6 inside the shell 2 adopts an elliptical structure, the pedal plate 4 and the door plate 6 are connected together through the rotating shaft 1 and the elastic washer 3, and an airflow guide groove is formed in the switch sphere.
The bottom of the pedal 4 is provided with a limiting block.
The pedal 4 is provided with a moment adjusting screw 5.
When the driver needs to warm the foot, trample the running-board 4 and rotate forward, switch door plant 6 also rotates to the direction of opening thereupon, when door plant 6 turns to vertical direction, when the position is opened entirely promptly, the door plant reaches unanimity with the air current direction of carrying, promptly keep being parallel with the air current, the stopper of running-board 4 bottom just in time contacts with installation floor 10, at this moment, running-board 4 is in one and inclines forward the state, stopper on running-board 4, under the combined action of the forward focus of friction locking force between elastic washer 3 and the running-board 4 and running-board 4, make the door plant be in the position of opening entirely, guaranteed that the air current in the air pipe flows to all around along the guide way on the switch hemispheroid, provide a comfortable local temperature field around the driver foot.
When a driver does not need to heat, the pedal 4 is pushed backwards, the inner rotating door plate 6 in the switch rotates towards the closing direction, the door plate is of an oval structure, the long axis length of the oval door plate is 46mm, the short axis length of the oval door plate is 40mm, the lower half part of the shell is a cylinder with the diameter of 40mm, the upper half part of the shell is an SR23mm hemisphere, the distance from the rotating shaft to the bottom plate is not less than 23mm of the half long axis length, and the height of the cylinder is not less than 23 mm; when the door plate rotates to form an angle of 70 degrees with the vertical plane, the door plate 6 is clamped on the side wall of the cylinder, the door plate 6 stops rotating, the pedal 4 tilts backwards at the moment, and the switch keeps a closed state under the combined action of the gravity center of the pedal tilting backwards and the friction locking force between the elastic washer 3 and the pedal 4.
The pedal is provided with a moment adjusting screw 5, and the rotating moment of the pedal can be adjusted by adjusting the force of the moment adjusting screw 5 on the pedal, so that the switch door plate stays at any position in the switch stroke.
