The housing upper cover 11, the housing lower cover 12, and the housing side wall 13 together define a housing accommodating space.
The poking assembly 2 is arranged at the top of the housing accommodating space. The poking assembly 2 consists of a movable poking rod 21, a poking top piece 22, a first torsion spring 23 and a second torsion spring 24. The movable lever 21 is movably coupled to the housing upper cover 11. The movable deflector rod 21 can be left and right shifted. In this embodiment, the movable lever 21 is coupled to the housing upper cover 11 by a lever pin.
The lower end of the movable deflector rod 21 is fixedly combined with the poking top piece 22 (the combination position is the middle position of the poking top piece 22). The toggle top 22 has an upwardly open arc structure, i.e., a C-shape.
The first torsion spring 23 is used for providing a restoring force for pulling the movable deflector 21 in the right direction. The second torsion spring 24 is used for providing a restoring force for pulling the movable deflector 21 in the left direction. By means of the first torsion spring 23 and the second torsion spring 24, the toggle top piece 22 keeps a neutral state under the action of no external force. In this embodiment, the first torsion spring 23 and the second torsion spring 24 are respectively located at the front and rear sides of the movable lever 21. The first torsion spring 23 corresponds to a first pin shaft. The first torsion spring 23 surrounds the first pin shaft. A first end of the first torsion spring 23 is a fixed end.

The electromagnetic assembly 3 consists of a fixed coil 30, a left movable ejector rod 31, a right movable ejector rod 32, a left movable iron core 33 and a right movable iron core 34. The stationary coil 30 has an upper stationary core 301 and a lower stationary core 302 spaced apart from each other by an up-down distance. The upper stationary core 301 is formed with a left ejector pin guide channel and a right ejector pin guide channel extending in the up-down direction. The left movable ejector rod 31 is positioned in the left ejector rod guide pore canal, and the length of the left movable ejector rod 31 is larger than that of the left ejector rod guide pore canal. The right movable ejector rod 32 is positioned in the right ejector rod guide duct, and the length of the right movable ejector rod 32 is larger than that of the right ejector rod guide duct. The lower stationary core 302 is formed with a left core guide hole and a right core guide hole extending in the up-down direction. The left movable iron core 33 is located in the left iron core guiding hole and the length of the left movable iron core 33 is greater than that of the left iron core guiding hole. The right movable iron core 34 is located in the right iron core guiding hole and the length of the right movable iron core 34 is greater than the length of the right iron core guiding hole.
When the fixed coil 30 is energized, the left movable iron core 33 and the right movable iron core 34 receive a magnetic force generated by the fixed coil 30, and tend to move upward.
The left movable ejector rod 31 and the left movable iron core 33 have a common axis, and the outer diameter of the left movable ejector rod 31 is smaller than the outer diameter of the left movable iron core 33, so as to ensure that the upward moving process of the left movable iron core 33 is stopped by the top surface of the left movable iron core 33 abutting against the bottom surface of the upper static iron core 301. Similarly, the right movable plunger 32 and the right movable core 34 have a common axis, and the outer diameter of the right movable plunger 32 is smaller than the outer diameter of the right movable core 34.
When the movable shift lever 21 is in a neutral state, the shift top piece 22 is respectively abutted against the left movable push rod 31 and the right movable push rod 32, so as to limit the left movable push rod 31 and the right movable push rod 32 to move upwards. The lower end of the left movable plunger 31 abuts against the upper end of the left movable core 33, the lower end of the left movable core 33 abuts against the left switch contact 41, and the left switch contact 41 is in a pressed state. The lower end of the right movable plunger 32 abuts against the upper end of the right movable core 34, the lower end of the right movable core 34 abuts against the right switch contact 42, and the right switch contact 42 is in a pressed state.
When the movable deflector 21 is in a leftward state, the deflector 22 abuts against the right movable ejector rod 32, and only the right movable ejector rod 32 is restricted from moving upward. When the movable deflector 21 is in a rightward state, the deflector 22 abuts against the left movable ejector rod 31, and only the left movable ejector rod 31 is restricted from moving upwards.
First mode of operation:
referring to fig. 2 and 3, when the operator dials the movable lever 21 in the left direction from the neutral state, the dial 22 is displaced in the right direction. At this time, the dial top 22 restricts only the upward movement of the right movable jack 32, and no longer restricts the upward movement of the left movable jack 31. The fixed coil 30 is energized, and under the combined action of the restoring force of the left switch contact 41 and the magnetic force of the fixed coil 30 on the left movable iron core 33, the left movable iron core 33 moves upwards along the left iron core guiding hole and drives the left movable ejector rod 31 to synchronously move upwards along the left ejector rod guiding hole until the top surface of the left movable iron core 33 abuts against the bottom surface of the upper static iron core 301. During the upward movement of the left movable core 33, the left switch contact 41 moves upward without being restricted by the left movable core 33, that is, the operation state of the left switch contact 41 changes from the pressed state to the released state. The fixed coil 30 is kept in an energized state, and the left movable push rod 31 is always in a high position, so that the movable push rod 21 is prevented from returning to a neutral state. Because the right movable ejector rod 32 is still in the limiting state, the positions of the right movable ejector rod 32, the right movable iron core 34 and the right switch contact 42 are all kept unchanged, that is, the working state of the right switch contact 42 is unchanged.
Referring to fig. 4 and 5, the aircraft operating mechanism gives a feedback signal, the fixed coil 30 is powered off, the left movable iron core 33 loses the magnetic force of the fixed coil 30 on the left movable iron core 33, the movable deflector 21 returns to the neutral state under the combined action of the first torsion spring 23 and the second torsion spring 24, and the deflector 22 pushes the left movable ejector rod 31 to move down along the left ejector rod guiding hole and drives the left movable iron core 33 to move down along the left iron core guiding hole, so as to return to the initial position. The left switch contact 41 moves down, i.e., the operation state of the left switch contact 41 returns to the pressed state. Because the right movable ejector rod 32 is still in a limited state, the positions of the right movable ejector rod 32, the right movable iron core 34 and the right switch contact 42 are all kept unchanged, that is, the working state of the right switch contact 42 is unchanged.
Second mode of operation:
the operator dials the movable lever 21 from the neutral state to the right, and at this time, the dial 22 restricts only the upward movement of the left movable jack 31, and no longer restricts the upward movement of the right movable jack 32. The fixed coil 30 is energized, and under the combined action of the restoring force of the right switch contact 42 and the magnetic force of the fixed coil 30 to the right movable iron core 34, the right movable iron core 34 moves up along the right iron core guiding hole and drives the right movable ejector rod 32 to move up synchronously along the right ejector rod guiding hole until the top surface of the right movable iron core 34 abuts against the bottom surface of the upper static iron core 301. During the upward movement of the right movable core 34, the right switch contact 42 moves upward without being restricted by the left movable core 33, that is, the operation state of the right switch contact 42 changes from the pressed state to the released state. The fixed coil 30 is kept in an energized state, and the right movable push rod 32 is always in a high position, so that the movable push rod 21 is prevented from returning to a neutral state. Because the left movable ejector rod 31 is still in a limited state, the positions of the left movable ejector rod 31, the left movable iron core 33 and the left switch contact 41 are all kept unchanged, that is, the working state of the left switch contact 41 is unchanged.
Referring to fig. 4 and 5, the aircraft operating mechanism gives a feedback signal, the fixed coil 30 is powered off, the right movable iron core 34 loses the magnetic force of the fixed coil 30 on the right movable iron core 34, the movable deflector 21 returns to the neutral state under the combined action of the first torsion spring 23 and the second torsion spring 24, and the deflector 22 pushes the right movable ejector rod 32 to move down along the right ejector rod guiding hole and drives the right movable iron core 34 to move down along the left iron core guiding hole, so as to return to the initial position. The right switch contact 42 moves downward, i.e., the operating state of the right switch contact 42 returns to the pressed state. Because the left movable ejector rod 31 is still in a limited state, the positions of the left movable ejector rod 31, the left movable iron core 33 and the left switch contact 41 are all kept unchanged, that is, the working state of the left switch contact 42 is unchanged.
The foregoing has outlined rather broadly the more detailed description of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present invention may be better understood. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
