Description

Technical Field

[0001] The utility model relates to the technical field of aircraft luggage compartments, in particular to a door lock mechanism of an aircraft luggage compartment. Background Art

[0002] The luggage compartment of an aircraft is used to place passengers' carry-on luggage. For the safety of the flight and passengers, the luggage compartment is closed during the flight. It may be opened in special circumstances, causing luggage and other items inside to fall, causing passenger injuries, etc.

[0003] In the prior art, for example, an adjustable aircraft luggage compartment lock is disclosed in the publication number CN113338722B, which states: The adjustable aircraft luggage compartment lock of the present invention adds an electromagnetic device to the existing aircraft luggage compartment lock mechanism, and conducts the circuit through the crew control switch SB or through sensor detection or limit switch, so that when the aircraft experiences severe turbulence or a malfunction requires forced landing, the aircraft can lock the luggage compartment in the first place, and without disconnecting the circuit, even if the aircraft experiences severe turbulence or the passengers use violent unlocking in a panic, the luggage compartment cannot be opened, thereby avoiding unnecessary casualties of passengers due to luggage.

[0004] In actual use, the locking ability of the middle single lock is not strong enough, and the load-bearing method is not good enough, and the pressure is concentrated on one point. When the internal luggage is heavy, the aircraft may encounter turbulence caused by airflow, which may cause the lock key to break and the luggage to fall, causing harm to the passengers. In addition, the working logic of the locking structure is that the internal locking structure and the internal power supply are bound. When the power supply is short-circuited or disconnected, the door lock structure cannot lock the aircraft luggage compartment, resulting in the aircraft luggage compartment being accidentally opened, making it difficult to ensure the safe storage of luggage in the luggage compartment. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-5 , which is the first embodiment of the utility model, provides the following technical solutions to achieve the above purpose: a door lock mechanism of an aircraft luggage compartment, comprising a luggage compartment 1, a drawer 2 is rotatably connected to the inner side of the luggage compartment 1, the drawer 2 is rotatably connected to the inner side of the luggage compartment 1 through a shaft, a load-bearing layer 3 is fixedly connected to the inner side of the drawer 2, and a longitudinal plate is provided on the inner side of the load-bearing layer 3 at the driving shaft 45 for the driving shaft 45 to be rotatably connected;

[0030] A door lock structure 4 is provided on the outside of the drawer 2, and a locking structure 5 is provided on the inside of the door lock structure 4;

[0031] The door lock structure 4 includes a shell 41, and there are two shells 41 in total, which are fixedly connected to the left and right sides of the drawer 2 and symmetrically arranged. The shell 41 is provided with a locking shaft 42, one end of the locking shaft 42 is fixedly connected to the shell 41, and the other end is fixedly connected to the drawer 2. The outer side of the locking shaft 42 is rotatably connected to a driven gear 43, and the two sides of the driven gear 43 are fixedly connected to locking pliers 44. The locking pliers 44 are fixedly connected to the two sides of the driven gear 43, and the locking pliers 44 are rotatably connected to the locking shaft 42.

[0032] A driving shaft 45 is provided on the inner side of the shell 41. The driving shaft 45 passes through the drawer 2 and is rotationally connected to the drawer 2 and the shell 41. A driving gear 46 is fixedly connected to the outer side of the driving shaft 45, wherein the driving gear 46 and the relatively close driven gear 43 are meshed with each other, and the two driven gears 43 are meshed with each other.

[0033] A switch 47 is fixedly connected to the outer side of the driving shaft 45 , and a torsion spring 48 is fixedly connected to the inner side of the switch 47 . One end of the torsion spring 48 is fixed to the switch 47 , and the other end is fixed to the vertical plate inside the load-bearing layer 3 .

[0034] A switch slot 49 is provided on one side of the drawer 2, and the switch 47 is located on the inner side of the switch slot 49. A locking rod 410 is fixedly connected to the inner side of the luggage compartment 1. The locking rod 410 is located on the inner wall of the luggage compartment 1 on the side close to the door lock structure 4, and is located at the center of the locking clamp 44 when the drawer 2 is closed. A locking slot 411 is provided on the driving gear 46, and the locking slots 411 are symmetrically arranged on both sides of the driving gear 46.

[0035] During use, under normal conditions, the luggage compartment 1 is in a closed state, that is, the drawer 2 is closed inside the luggage compartment 1. To open it, one only needs to turn the switch 47, which will drive the driving shaft 45 and the driving gear 46 on the driving shaft 45 to rotate, and the driving gear 46 and the relatively close driven gear 43 are meshed, and the driven gears 43 are meshed with each other, which will cause the locking clamp 44 fixedly connected to the driven gear 43 to rotate, thereby opening the locking clamp 44 locked on the locking rod 410, and opening the entire drawer 2. After releasing the switch 47, the switch 47 can be reset due to the presence of the torsion spring 48.

[0036] Example 2

[0037] Reference Figure 1-6 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the locking structure 5 includes a lock key 51, the lock key 51 is located on the upper and lower sides of the driving gear 46, and the lock key 52 has the same shape and size as the locking groove 411. In the normal state, the lock key 51 does not contact the driving gear 46, and springs 52 are fixedly connected to both ends of one side of the lock key 51. A telescopic rod is provided on the inner side of the spring 52. The upper telescopic rod is fixedly connected to the shell 41, and the lower telescopic rod is fixedly connected to the drawer 2.

[0038] A magnet 53 is fixedly connected to the middle of one side of the lock key 51, and the spring 52 and the magnet 53 are located on the same side of the lock key 51. The spring 52 is located at both ends, and the magnet 53 is located in the middle. An electromagnetic block 54 is arranged on the upper part of the magnet 53. When the electromagnetic block 54 is powered on, it generates an attractive force with the magnet 53, so that the lock key 51 can be bound to the outside of the driving gear 46. In this state, the spring 52 is in a compressed state. A connecting end 55 is fixedly connected to one side of the electromagnetic block 54. The connecting end 55 is mainly used to energize the electromagnetic block 54 and is connected to the switch 47 and other circuits. In the short circuit, open circuit or flight state, the switch 47 is touched and the power connection will be directly disconnected.

[0039] During use, when the aircraft encounters airflow or a line failure in flight, the connection end 55 will be powered off, and the electromagnetic block 54 in the connection end 55 will lose its magnetic force, and the spring 52 will lose its restraint and will pop out. The springs 52 on both sides will pop out the lock key 51 to the inside of the locking groove 411, clamping the driving gear 46 so that it cannot rotate, thus achieving a locked state.

[0040] In addition, a pressure sensor can also be added at the connection of the lock clamp 44 to prevent the lock clamp 44 from being opened due to excessive pressure when encountering airflow. When the lock clamp 44 is subjected to excessive pressure, the passage of the electromagnetic block 54 can be directly cut off to directly lock the door lock.

[0041] The remaining structures are the same as those of Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
