[0015] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. It should be noted that the description of these implementations is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] See also Figures 1 to 3 , the figure shows a landing gear handle control device. The landing gear handle control device comprises: a handle assembly 1, a motor assembly 2, an electromagnet assembly 3 and the like.

[0017] The handle assembly 1 comprises a handle bar 11 and a handle shaft 12. The handle bar 11 is fixedly connected to the handle shaft 12. That is, the handle bar 11 and the handle shaft 12 rotate synchronously. An unlocking switch 13 is fixed to the handle bar 11. A protruding rib 14 and a sector gear 15 are fixed to the handle shaft 12. Both the protruding rib 14 and the sector gear 15 extend radially. The protruding rib 14 has a rib hole. Preferably, the protruding rib 14 and the sector gear 15 are staggered in the circumferential direction. In some embodiments, the handle shaft 12 is made of stainless steel and is in the shape of an incomplete cylinder. The handle shaft 12 and the corresponding inner holes of the handle bar 11 are assembled in a transition fit. At this time, the shape feature of the handle shaft 12 can play an anti-rotation role, cooperate with the handle bar 11, and transmit torque.

[0018] The motor assembly 2 comprises a driving motor 21 and a gear pair 22. One of the gears in the gear pair 22 is meshed with the sector gear 15. That is, the driving motor 21 can drive the handle shaft 12 to move through the gear pair 22 to achieve automatic movement of the handle bar 11. Preferably, the motor assembly 2 further comprises a clutch. The clutch acts as a clutch between the driving motor 21 and the gear pair 22. Preferably, the driving motor 21 can be remotely controlled.

[0019] The electromagnet assembly 3 has a movable iron core, etc. The movable iron core is displaced to the rib hole in the energized state, and at this time, the movable iron core restricts the protruding rib 14, so that the handle bar 11 is locked and cannot be moved. The movable iron core is displaced out of the rib hole in the non-energized state, and at this time, the movable iron core no longer restricts the protruding rib 14, so that the handle bar 11 is unlocked and can be moved. Whether the electromagnet assembly 3 is energized is controlled by the unlocking switch 13 or the onboard electrical signal.

[0020] Preferably, see Figure 4 The unlocking switch 13 includes: a switch housing 1, a micro switch 132, a button portion 133, a button spring 134, etc. The switch housing is fixed to the handle bar 11 by screws. The switch housing 1 contains the micro switch 132, the button portion 133, and the button spring 134. In some embodiments, the switch housing 1 is made of epoxy glass cloth board, the button portion 133 is made of plastic material, the button spring 134 is made of stainless steel, and the micro switch 132 is a mature product.

[0021] Preferably, the handle bar 11 has a handle gripping portion. Figure 4The handle grip portion includes: a light-transmitting cover 16 and a light-emitting component 17. The light-transmitting cover 16 can be made of aviation organic glass material, which has good light transmittance. Figure 5 , the light-emitting component 17 has a PCB171, a light-isolating ring 172, a light-transmitting plate 173, a diffuser 174, etc. The PCB171 is fixed to the top surface of the handle rod 11 by screws. The light-isolating ring 172 made of an aluminum alloy plate material is fixed on the PCB171, and the light-isolating ring 172 is respectively stacked with: the light-transmitting plate 173 made of a colorless transparent plastic plate material and the diffuser 174 made of two filter film materials, plus one light-transmitting plate 173, a total of four plates. The light generated by the PCB171 after power is supplied will be uniformly radiated to the light-transmitting cover 16 through the combination of the light-transmitting plate 173 and the diffuser 174, thereby realizing the light-emitting function of the handle grip.

[0022] Preferably, the motor assembly 2 further comprises: an angular displacement sensor 23. The angular displacement sensor 23 is used to detect the rotation angle of the handle shaft 12, that is, to determine the pulling angle of the handle rod 11.

[0023] The landing gear handle operating device has two modes: manual and automatic. Manual mode: continuously press the unlocking switch 13, at which time the handle shaft 12 is in the unlocked state, and manually pull the handle rod 11 to trigger the micro switches 132 on both sides of the pulling direction. If the unlocking switch 13 is released, the handle shaft 12 turns to the locked state. Automatic mode: unlock the handle rod 11 through the on-board electrical signal, and the drive motor 21 transmits torque to the handle shaft 12, automatically pulling the handle rod 11 to trigger the micro switches 132 on both sides of the pulling direction. If the on-board electrical signal is disconnected, the handle shaft 12 turns to the locked state.

[0024] The above only expresses the implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
