Description

Technical Field

[0001] The utility model relates to the technical field of eVTOL aircraft, and more specifically, to an eVTOL aircraft cabin door. Background Art

[0002] eVTOL stands for electric vertical take-off and landing aircraft. This type of aircraft drives the cabin to fly through the high-speed rotation of the propeller, and the cabin door is often connected by a sliding connection. In the sliding connection, a slide is needed to support the pulley, and the pulley drives the cabin door to move, thereby realizing the opening and closing of the cabin door. However, when passengers pass through the cabin door, some small debris and dust particles may enter the slide, which may cause the cabin door to be blocked over time, making it inconvenient to use. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an eVTOL aircraft cabin door, which has the advantage of being easy to clean.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an eVTOL aircraft cabin door, comprising a door body and an installation door frame, a sliding groove being provided on the rear side of the installation door frame, a sliding wheel being movably connected to the front side of the door body, a cylinder being fixedly connected to the inner cavity of the door body, a piston plate being fixedly connected to the output shaft of the cylinder, a piston cylinder being fixedly connected to the inner cavity of the door body, a one-way air intake valve being fixedly connected to the top end of the piston cylinder, a blowing pipe 1 being fixedly connected to the left end of the blowing pipe 1, and a blowing nozzle being fixedly connected to the left side of the blowing pipe 1.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The utility model starts the cylinder to drive the piston plate to rise and fall in the inner cavity of the piston cylinder when the door body is pulled toward the direction of the door frame installation. When the piston plate rises in the inner cavity of the piston cylinder, the air in the inner cavity of the piston cylinder is squeezed. When the piston plate descends in the inner cavity of the piston cylinder, external air is drawn into the inner cavity of the piston cylinder through the one-way air intake valve to replenish the air in the inner cavity of the piston cylinder.

[0012] 2. The utility model closes the cabin after the door body overlaps with the mounting door frame, then starts the diverter control valve to close the connection between the blowing pipe and the piston cylinder, opens the connection between the connecting pipe and the piston cylinder, and then the piston plate squeezes the air in the inner cavity of the piston cylinder, and the squeezed air is transported to the inner cavity of the sealing airbag along the connecting pipe, thereby increasing the volume of the sealing airbag, thereby releasing the sealing airbag from the mounting door frame, and completely sealing the door body and the mounting door frame, thereby avoiding air circulation, thereby preventing external cold air from entering the cabin at high altitude and affecting the temperature inside the cabin.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the utility model provides an eVTOL aircraft cabin door, including a door body 1 and a mounting door frame 2, a slide groove 3 is opened on the rear side of the mounting door frame 2, a sliding wheel 4 is movably connected to the front side of the door body 1, a cylinder 5 is fixedly connected to the inner cavity of the door body 1, a piston plate 6 is fixedly connected to the output shaft of the cylinder 5, a piston cylinder 7 is fixedly connected to the inner cavity of the door body 1, a one-way air intake valve 8 is fixedly connected to the top end of the piston cylinder 7, a blowing pipe 9 is fixedly connected to the top end of the blowing pipe 9, a blowing pipe 2 10 is fixedly connected to the left end of the blowing pipe 9, and a blowing nozzle 11 is fixedly connected to the left side of the blowing pipe 9;

[0022] In the process of pulling the door body 1 to move in the direction of installing the door frame 2, the starting cylinder 5 drives the piston plate 6 to rise and fall in the inner cavity of the piston cylinder 7. When the piston plate 6 rises in the inner cavity of the piston cylinder 7, the air in the inner cavity of the piston cylinder 7 is squeezed. When the piston plate 6 descends in the inner cavity of the piston cylinder 7, the external air is drawn into the inner cavity of the piston cylinder 7 through the one-way air intake valve 8 to replenish the air in the inner cavity of the piston cylinder 7. The squeezed air is transported to the blowing nozzle 11 along the blowing pipe 1 9 and the blowing pipe 2 10, and then blown out to the inner cavity of the slide groove 3 through the blowing nozzle 11, thereby blowing away foreign matter such as dust particles in the inner cavity of the slide groove 3, thereby preventing dust and other particles from affecting the normal rolling of the sliding wheel 4 in the inner cavity of the slide groove 3.

[0023] Among them, the top of the piston cylinder 7 is fixedly connected to a connecting pipe 12, and the left and right sides of the connecting pipe 12 are fixedly connected to sealing air bags 13. The middle of the connecting pipe 12 is fixedly connected to a diverter control valve 14, and the diverter control valve 14 is connected to the blowing pipe 9;

[0024] After the door body 1 overlaps with the installation door frame 2, the door body 1 closes the passenger cabin, and then the diverter control valve 14 is started to close the connection between the blowing pipe 9 and the piston cylinder 7, and the connection between the connecting pipe 12 and the piston cylinder 7 is opened. Then the piston plate 6 squeezes the air in the inner cavity of the piston cylinder 7, and the squeezed air is transported along the connecting pipe 12 to the inner cavity of the sealing airbag 13, thereby increasing the volume of the sealing airbag 13, thereby releasing the sealing airbag 13 from the installation door frame 2, and completely sealing the door body 1 and the installation door frame 2, thereby avoiding air circulation, thereby preventing external cold air from entering the cabin at high altitude and affecting the temperature inside the cabin.

[0025] Among them, the blowing nozzle 11 is inclined towards the direction of the chute 3, and there are two blowing nozzles 11, which are fixedly connected to the blowing pipe 1 9 and the blowing pipe 2 10 respectively;

[0026] By tilting the blowing nozzle 11 toward the chute 3, the air blown out of the blowing nozzle 11 can be blown toward the chute 3, thereby cleaning the dust and other particulate matter in the inner cavity of the chute 3, avoiding a large number of foreign objects in the inner cavity of the chute 3 and affecting the normal movement of the sliding wheel 4.

[0027] The rear side of the door body 1 is provided with a ventilation hole 16, which is located behind the one-way air intake valve 8;

[0028] Through the ventilation hole 16 on the rear side of the door body 1, air can enter the inner cavity of the piston cylinder 7 from the one-way air inlet valve 8, thereby replenishing the air in the inner cavity of the piston cylinder 7, and then the piston cylinder 7 can continuously output air to the blowing nozzle 11 and the sealing air bag 13, thereby cleaning the inner cavity of the slide groove 3 and increasing the volume of the sealing air bag 13.

[0029] The front side of the door body 1 is fixedly connected with a handle 15, which is located inside the door frame 2;

[0030] Through the handle 15 on the front side of the door body 1, it is convenient for the staff to pull the handle 15 to move the door body 1, so that the sliding wheel 4 can roll in the inner cavity of the slide groove 3, and then the handle 15 is located inside the door frame 2, so that the staff can grab the handle 15 when opening or closing the door body 1.

[0031] Among them, the sealing airbag 13 is connected to the inner cavity of the connecting pipe 12, and a through slot is opened on the right side of the installation door frame 2;

[0032] The sealing airbag 13 is connected to the inner cavity of the connecting tube 12, so that the air in the inner cavity of the piston cylinder 7 can enter the inner cavity of the sealing airbag 13 along the connecting tube 12, and then pass through the through groove on the right side of the installation door frame 2, so that the sealing airbag 13 can cross the through groove and overlap with the installation door frame 2.

[0033] The working principle and usage process of the present invention are as follows: the staff pulls the handle 15 by hand to drive the door body 1 to move, thereby causing the sliding wheel 4 to roll in the inner cavity of the slide groove 3, so that the door body 1 moves along the axial direction of the slide groove 3, and starts the cylinder 5 to drive the piston plate 6 to move up and down in the inner cavity of the piston cylinder 7. When the piston plate 6 rises in the inner cavity of the piston cylinder 7, the air in the inner cavity of the piston cylinder 7 is squeezed along the blowing pipe 1 9 and the blowing pipe 2 10 to the blowing nozzle 11. When the piston plate 6 descends in the inner cavity of the piston cylinder 7, the external air is drawn into the inner cavity of the piston cylinder 7 through the one-way air inlet valve 8 to replenish the piston cylinder 7, and then blown out to the inner cavity of the slide groove 3 through the blowing nozzle 11, thereby blowing away the dust and other particulates in the inner cavity of the slide groove 3;

[0034] When the door body 1 is completely closed with the mounting door frame 2, the diversion control valve 14 is started to block the blowing pipe 9 and ventilate the connecting pipe 12, and then the air is transported to the inner cavity of the sealing airbag 13 through the connecting pipe 12, so that the volume of the sealing airbag 13 increases, thereby sealing the sealing airbag 13 and the mounting door frame 2, thereby preventing air circulation.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
