The reset elastic member 340 may be a spring, the fixed end connector 100 is provided with a spring seat 120, a portion of the swinging member 310 away from the hinge end 311 is provided with a spring connection point, the spring is connected between the spring seat 120 and the spring connection point, when the locking mechanism 300 is in a locked state, the spring can tighten the swinging member 310, so that the swinging member 310 keeps stable, if the locking mechanism 300 needs to be unlocked, the handle drives the swinging member 310 to rotate against the tension of the spring, and after the handle is removed, the swinging member 310 can be reset to an initial position under the tension of the spring, namely, the locking mechanism 300 is in the locked state.
In this embodiment, since the swinging member 310 is connected to the fixed end connector 100 by the tension spring, the lock pin 320 can be kept at the locking position by the spring, and the force of the spring can ensure that the lock pin 320 is not released under the maximum flying vibration or impact condition.
Referring to fig. 4 and 5, in some embodiments, the locking mechanism 300 further includes a connecting member 330, the locking pin 320 is disposed on the connecting member 330, the connecting member 330 is rotatably mounted on the swinging member 310, and a plane of the rotating direction of the connecting member 330 is parallel to the swinging plane of the swinging member 310. After the arrangement, when the swinging member 310 swings, the movement direction of the lock pin 320 is kept in the axial direction of the lock pin 320 by the rotation of the connecting member 330 relative to the swinging member 310, and the lock pin 320 does not rotate around the hinge end 311 along with the swinging member 310, so that the insertion or separation of the lock pin 320 from the first insertion hole 110 and the second insertion hole 210 is smoother.
In this embodiment, when two locking pins 320 are provided, the two locking pins 320 are connected to the same connecting piece 330, for example, two ends of the connecting piece 330 respectively correspond to the first inserting holes 110 of the two locking portions, the two locking pins are respectively connected to two ends of the connecting piece 330, the middle part of the connecting piece 330 is rotatably connected with the swinging piece 310, for example, a rotating connection point 331 is provided at the middle part of the swinging piece, the connecting piece is rotatably connected to the rotating connection point 331, and when the swinging piece 310 is driven by the rocker, the connecting piece 330 drives the two locking pins 320 to move axially synchronously, so as to realize synchronous unlocking or locking.
In some embodiments, locking mechanism 300 is disposed in an interior region between fixed end connector 100 and folding end connector 200, which reduces space occupation, and provides a more compact structure for use in a multi-rotor aircraft.
In this embodiment, the locking pin 320 includes a connection end and a socket end, the connection end is connected to the connection member 330, the socket end of the locking pin 320 is tapered, and it is difficult for the second socket 210 of the folding end connector 200 and the first socket 110 of the fixing end connector 100 to be completely coaxial after being unfolded in place due to processing and assembly errors. The application sets the plugging end of the lock pin 320 to be conical, and uses lateral force component to rectify the first plugging hole 110 and the second plugging hole 210 to be coaxial.
In this embodiment, since the lock pin 320 has a deviation rectifying function, the driving force required for the axial movement of the lock pin 320 in the deviation rectifying process is very large, and it is difficult to push the lock pin into place by a person. The application utilizes the principle that the driving force arm of the rocker is larger than the resistance arm of the lock pin acting on the rocker 310 by the cooperation of the rocker 310, and a user can push the lock pin to lock or unlock without too large force when operating.
Correspondingly, the application also provides an aircraft, which comprises a fuselage and a horn, wherein the horn is provided with the horn locking mechanism 300 in any embodiment, and the horn locking mechanism 300 is described in any embodiment above, and is not repeated here.
