Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a small aircraft luggage compartment door, which includes an outer skin and an inner basin 2, a trigger type quick release lock 1 is disposed between the outer skin and the inner basin, the trigger type quick release lock includes an unlocking button 3, a locking button 4, a support 5, a rocker arm 6, a lock tongue 7 and a torsion spring 8, the support is fixed on the inner surface of the outer skin, the unlocking button is disposed at one end of the rocker arm, the locking button is disposed at one end of the lock tongue, the rocker arm and the lock tongue are connected with the support through the torsion spring, the torsion spring provides a rotation acting force for the rocker arm and the lock tongue, the rotation of the support limits the rocker arm, and the rotation. The lock further comprises a lock cylinder 10 and a lock cylinder rocker 11, the lock cylinder is arranged on the outer skin, the lock cylinder rocker is located between the outer skin and the inner basin-shaped piece, and the lock cylinder rocker locks the unlocking button.
The trunk door is locked by a trigger type quick release lock, and the trigger type quick release lock is locked by a lock cylinder controlled by a key. The working principle is as follows: when the lock is unlocked, the lock tongue bounces when the unlocking button is pressed; when the lock is closed, the lock button is pressed, and the lock tongue is kept at a closed position under the action of the torsion spring and the rocker arm.
The luggage compartment door mainly comprises an outer covering, an inner basin-shaped piece, a hinge, a sealing strip and the like.
The outer skin and the inner pot are the skeleton of the trunk door, and since the locking mechanism is located between the inner pot and the outer skin, 3 through holes 12 are made in the inner pot to provide access for installation and maintenance of the mechanism, and the pot is also reinforced around the perforated area. In order to improve the rigidity of the door, a circular reinforcing socket 13 is designed in the middle of the inner basin-shaped part, and the bottom surface of the reinforcing socket is tightly attached to the outer skin and riveted with the outer skin to form a whole.
The external hinge 9 is suitable for being adopted because the peripheral appearance of the trunk door is relatively straight. According to the size and the weight of the door, two hinges are arranged for the luggage compartment door, the upper hinge is close to the ventilation window, and the lower hinge is located near the round corner of the front lower part of the outer skin. In order to further improve the stability of the luggage compartment door, the hinge axis is close to the appearance of the machine body in front of the luggage compartment door, the intersection point of the upper hinge plane and the hinge axis is 4.9 mm away from the theoretical appearance of the machine body, and the intersection point of the lower hinge plane and the hinge axis is 9.5 mm away from the theoretical appearance of the machine body. The hinge connected to one side of the cabin door is formed by bending a stainless steel plate, and the part connected to one side of the cabin body is a stainless steel machining part.
To prevent the ingress of rain and to ensure that the trunk door is impervious to wind around during flight, sealing tape is provided around the door. The sealing tape is made of sponge rubber material, the material has larger compression deformation and good rebound resilience, and can effectively meet the sealing requirements of different parts of the circumference of the cabin door. The sealing strip is bonded at the round angle of the periphery of the basin-shaped piece through adhesive.
In order to reduce the processing cost of the inner basin-shaped part, the material is changed from aluminum alloy into composite material, the part thicknesses are different in different regions, the thickness of the central region is 0.964 mm, the thickness of the outermost ring region is 1.446 mm, and the thickness of a transition region sandwiched between the two regions is 1.205 mm.
