The fact that the longitudinal direction of the stretcher 300 is parallel to the width direction of the access opening 110 means that the longitudinal direction of the stretcher 300 is parallel to the width direction of the access opening 110.
Specifically, the stretcher 300 is arranged on the cabin door 200, and patients can be transported into the carrying cabin of the carrying tool 100 or out of the carrying cabin of the carrying tool 100 by opening and closing the cabin door 200, so that compared with the scheme that the traditional stretcher is lifted into and lifted out of the carrying cabin by manpower, the scheme can save the time required by the stretcher 300 to carry, can effectively provide quick boarding and transportation functions for patients inconvenient to move and needing to be fixed by the stretcher 300, and can improve the labor cost of rescue workers and the transportation efficiency, thereby improving the rescue efficiency; in addition, the traditional stretcher is fixed after being transported into the carrying cabin, so that the situation that the carrying vehicle jolts in the driving process and the patient is injured secondarily is avoided, the stretcher 300 is directly arranged on the cabin door 200, the procedure of re-fixing the stretcher after being transported into the carrying cabin can be avoided, the time is further saved, and the rescue efficiency is improved; furthermore, the stretcher 300 is directly arranged on the cabin door 200, so that the redundant weight of the single structures of the cabin door 200 and the stretcher 300 can be reduced, the space of the carrying cabin is saved, the space utilization rate of the carrying cabin is effectively improved, and the length direction of the stretcher 300 is parallel to the width direction of the inlet and outlet 110, so that the installation stability of the stretcher 300 can be improved. Therefore, the technical scheme of the invention can improve the efficiency of transporting patients into the carrying cabin of the carrying vehicle 100 and out of the carrying cabin of the carrying vehicle 100, thereby improving the rescue efficiency.
Optionally, in this embodiment, the door 200 is rotatably connected to the bottom of the access port 110, the door 200 is opened rotationally downward, and the stretcher 300 is rotatably disposed on the door 200, so that it can be understood that when the door 200 is opened rotationally downward, the stretcher 300 rotates relative to the door 200 and always maintains a state parallel to the ground, so that when a patient is transported out of the carrying cabin, the patient can also always maintain a state parallel to the ground; similarly, when the cabin door 200 is rotated upwards to be closed, the stretcher 300 also rotates relative to the cabin door 200, and always keeps a state parallel to the ground, so that when a patient is transported into the carrying cabin, the patient can always keep a state parallel to the ground, and the patient can be prevented from tilting, and the comfort of the patient is improved. Of course, the present invention is not limited thereto, and in other embodiments, the door 200 may be rotatably connected to the side of the access opening 110, and the door 200 may be opened in a left or right direction.
Furthermore, when the door 200 is rotated downward to be opened, the stretcher 300 rotates relative to the door 200 to keep a state parallel to the ground, and the stretcher 300 can also be used as a pedal for a rescue worker to step on; the traditional aircraft pedal is designed to be smaller and smaller for saving weight and reducing resistance, and only one person can enter and exit the carrying cabin at a time, so that the cabin entering and exiting efficiency is particularly important for the rescue type aircraft. According to the scheme, the stretcher 300 and the foot pedals are subjected to structural fusion design, the traditional pedal arrangement can be omitted, so that the space utilization rate can be improved, the length of the stretcher 300 can meet the requirement that three people come in and go out of a carrying cabin of the transfer stretcher door at the same time, and the rescue efficiency in rescue tasks is improved. The boarding mode of the traditional transfer stretcher door is single, the boarding mode is mainly arranged in the mode of an external pedal, and the boarding pedal at the outer side can also increase the aerodynamic resistance of the airplane. The stretcher 300 is used as a pedal and can be folded into the carrying cabin, the aerodynamic shape of the aircraft is not damaged in the driving process, and the aerodynamic resistance of the aircraft with the fixed wing cruising ability can be effectively reduced, so that the energy consumption is reduced.
Referring to fig. 2 to 6, alternatively, the stretcher 300 has a pedal state in which the door 200 is opened and a stretcher state in which the stretcher 300 is parallel to the ground; in the stretcher state, the cabin door 200 is opened or closed, and the stretcher 300 is parallel to the ground; it will be appreciated that the pedal state allows a user to step in and out of the carrying pod, and the stretcher 300 in the stretcher state is parallel to the ground, and the stretcher 300 can be used as a stretcher for fixing a patient regardless of whether the door 200 is in the open or closed state, and when the patient needs to be fixed.

Further, the stretcher 300 is in a stretcher state, the locking device is in a semi-locking state, namely, the locking device only provides torque for the stretcher 300, the rotating speed of the stretcher 300 is slowed down, namely, the stretcher 300 is fixed on a wounded person in the driving process of the transferring stretcher door, and when the transferring stretcher door jolts, the locking device provides a certain damping for the stretcher 300, so that the swinging amplitude of the stretcher 300 is slowed down, the comfort of a patient is improved, and the stretcher 300 is prevented from rotating rapidly along with the transferring stretcher door.
Referring to fig. 4 and 6, optionally, in the present embodiment, the locking device is configured as a damping motor 400, and the damping motor 400 is configured to ensure that the stretcher 300 is stable and controllable during the closing and opening of the door 200, and to reduce the sense of rotational jolt felt by the wounded during driving, so as to facilitate increasing the safety of the stretcher 300. Of course, the present invention is not limited thereto, and in other embodiments, the locking device may lock the damping washer, so that the stretcher 300 is locked by the lock when the stretcher 300 is in the pedal state and the storage state, and the damping washer is disposed between the door 200 and the stretcher 300 when the stretcher 300 is in the stretcher state, so as to slow down the rotation speed of the stretcher 300; the stretcher 300 can unlock the lock during the switching process of the pedal state, the storage state and the stretcher state, so that the stretcher 300 can freely rotate relative to the cabin door 200.
Optionally, the cabin door 200 is provided with a plurality of first mounting frames 210, and the stretcher 300 is rotatably connected with the first mounting frames 210; the provision of the first mounting frame 210 may facilitate the installation and placement of the stretcher 300.
Alternatively, in the present embodiment, two first mounting frames 210 are provided, and the two first mounting frames 210 are spaced apart along the width direction of the cabin door 200, and two ends of the stretcher 300 are respectively connected with one first mounting frame 210 in a rotating manner; it will be appreciated that securing from both ends of the stretcher 300 may increase the stability of the installation of the stretcher 300. Of course, the present invention is not limited thereto, and in other embodiments, only one first mounting frame 210 may be provided, and the first mounting frame is disposed in the middle of the stretcher 300 and is rotatably connected to the stretcher 300.
Optionally, in this embodiment, two second mounting frames 310 are respectively disposed at two ends of the stretcher 300, and a first mounting frame 210 is rotatably connected to a second mounting frame 310, so that an operation space of a connection procedure of the first mounting frame 210 of the stretcher 300 can be increased, and the stretcher 300 can be conveniently installed. Of course, the present invention is not limited thereto, and in other embodiments, two ends of the stretcher 300 may be directly rotatably connected to the first mounting frame 210.
Optionally, in the present embodiment, the first mounting frame 210 and/or the second mounting frame 310 are arranged in a triangular frame; it will be appreciated that providing the first mount 210 and/or the second mount 310 as a frame for the stretcher 300 according to the triangle-shaped stability principle not only reduces weight, but also increases the stability of the first mount 210 and the second mount 310, thereby increasing the stability of the stretcher 300. Of course, the present invention is not limited thereto, and in other embodiments, the first mounting frame 210 and/or the second mounting frame 310 may be configured as a triangle panel.
