Detailed Description
In order to make the objects and technical solutions of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. In general, the components of the embodiments of the invention described and illustrated in the drawings can be realized in other different details as well as variations in size. In the drawings of the embodiments of the present invention, in order to describe the operation principle of each element in the door lock mechanism more clearly, the size, dimension and shape of each component inside the structure cannot be limited.
As shown in fig. 1, the present invention provides a schematic structural diagram of a cabin door lock mechanism for an intelligent low-idling human aircraft, which includes a first component 1 disposed outside a cabin body and a second component 2 disposed inside a cabin door; the detail view of the first assembly 1 is shown in fig. 2a, the first assembly 1 includes a first assembly holder 101, a lock pin 102, a pull ring 103, and a first return spring 104, the lock pin 102 is disposed in a guide hole of the first assembly holder 101 and can slide linearly along the guide hole of the first assembly holder 101; the end of the lock pin 102 is fixedly connected with a pull ring 103, the pull ring 103 can drive the lock pin 102 to linearly slide back and forth by pushing or pulling, and the first return spring 104 is arranged on the lock pin 102 and used for returning the lock pin 102; the first assembly support 101 is installed on the outer side of the cabin body in an embedded mode, and the pull ring 103 extends into the cabin body through an opening of the cabin body; an operator can unlock the cabin door in the cabin body by pulling the pull ring 103 upwards so as to leave the cabin body, the lock pin 102 is reset under the action of the first return spring 104 after unlocking, and the reset pressure of the lock pin 102 at the maximum stroke position is not more than 20N after the next locking operation.
