[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 5 As shown, the utility model provides an aviation seat for an eVTOL aircraft, including a seat body 1, the bottom end of the seat body 1 is fixedly connected to a cylinder 2, the output shaft of the cylinder 2 is fixedly sleeved with a piston plate 1, the bottom end of the seat body 1 is fixedly connected to an air reservoir 4, the right side of the air reservoir 4 is fixedly connected to an output pipe 5, the front and rear sides of the output pipe 5 are fixedly connected to a piston cylinder 6, the inner cavity of the piston cylinder 6 is fixedly connected to a shock-absorbing spring 7, the top end of the shock-absorbing spring 7 is fixedly connected to a piston plate 2 8, the bottom end of the piston plate 2 8 is fixedly connected to a supporting foot 9, the bottom end of the piston cylinder 6 is fixedly connected to a damping ring 10, and the top end of the piston cylinder 6 is fixedly connected to a connecting pipe 11;

[0022] By starting the cylinder 2, the piston plate 3 is driven to move in the inner cavity of the air cylinder 4, thereby extracting or squeezing the air in the inner cavity of the air cylinder 4, and extracting or squeezing the air in the inner cavity of the piston cylinder 6 through the output pipe 5, thereby increasing or decreasing the amount of air in the inner cavity of the piston cylinder 6, causing the seat body 1 at the top end of the piston cylinder 6 to rise or fall, and in the event of bumps, the elasticity of the shock-absorbing spring 7 and the air pressure in the inner cavity of the piston cylinder 6 can be used for shock absorption, thereby realizing that the height of the seat body 1 can be adjusted according to the height of the passenger, and in the event of bumps, the elasticity of the shock-absorbing spring 7 and the air pressure in the inner cavity of the piston cylinder 6 can be used for shock absorption, thereby improving the comfort of passengers when riding.

[0023] The inner cavity of the seat body 1 is fixedly connected to a servo motor 12, the output shaft of the servo motor 12 is fixedly sleeved with a threaded rod 13, the surface of the threaded rod 13 is meshed with a leg support plate 14, and the inner cavity of the leg support plate 14 is movably sleeved with a guide rod 15;

[0024] By starting the servo motor 12 to drive the threaded rod 13 to rotate, the threaded rod 13 rotates and drives the leg support 14 engaged with it to move along the axial direction of the threaded rod 13 and the guide rod 15, so that the leg support 14 extends out of the inner cavity of the seat body 1, and the length of the leg support 14 extended is adjusted by the rotation of the threaded rod 13. Then, the passenger's legs are supported by the leg support 14, and the length that the leg support 14 can support can be changed according to the length of the passenger's legs, thereby further improving the passenger's comfort when riding.

[0025] Among them, the support foot 9 is movably sleeved in the inner cavity of the damping ring 10, the piston plate 2 8 is attached to the inner wall of the piston cylinder 6, and the support foot 9 is located at the center of the inner cavity of the shock absorbing spring 7;

[0026] The supporting foot 9 is movably sleeved in the inner cavity of the damping ring 10, so that the damping ring 10 can damp the supporting foot 9, so that the shock-absorbing spring 7 can slow down the rate of raising and lowering of the piston cylinder 6 when vibrating, and then the piston plate 2 8 is attached to the inner wall of the piston cylinder 6, so that the air pressure in the inner cavity of the piston cylinder 6 can stably squeeze the piston plate 2 8, thereby achieving shock absorption through air pressure.

[0027] There are four piston cylinders 6, and the inner cavities of the four piston cylinders 6 are connected by a connecting pipe 11;

[0028] By providing the connecting tube 11 , the air in the inner cavity of the air storage cylinder 4 can evenly enter the inner cavity of each piston cylinder 6 , thereby making the heights of the four piston cylinders 6 consistent.

[0029] The air reservoir 4 is connected to the inner cavity of the piston cylinder 6 through the output pipe 5, and the bottom end of the supporting foot 9 is a disc;

[0030] The air cylinder 4 is connected to the inner cavity of the piston cylinder 6 through the output pipe 5, so that when the piston plate 3 squeezes the air in the inner cavity of the air cylinder 4, the air in the inner cavity of the air cylinder 4 can enter the inner cavity of the piston cylinder 6 along the output pipe 5, thereby changing the air pressure in the inner cavity of the piston cylinder 6. During installation, the support foot 9 is connected to the floor. The connection method can be bolt connection or other methods. The bottom end of the support foot 9 is a disc, thereby increasing the connection area between the support foot 9 and the floor.

[0031] Among them, the front and rear sides of the leg support plate 14 are both provided with a movable groove 16, and the guide rod 15 is movably sleeved in the inner cavity of the movable groove 16;

[0032] Through the movable grooves 16 on the front and rear sides of the leg support plate 14, the guide rod 15 can be movably sleeved in the inner cavity of the movable groove 16, and then when the threaded rod 13 rotates to drive the leg support plate 14 to move, the leg support plate 14 can be positioned and guided by the guide rod 15.

[0033] A circular hole is opened on the left side of the leg support plate 14, and the guide rod 15 is attached to the inner wall of the circular hole. The right side of the guide rod 15 is fixedly connected to the limit plate 17;

[0034] By fitting the guide rod 15 to the inner wall of the circular hole, the size of the circular hole is the same as that of the guide rod 15, so that when the leg support 14 is far away from the inner cavity of the seat body 1, the leg support 14 can be limited by the limit plate 17, thereby preventing the leg support 14 from completely leaving the inner cavity of the seat body 1 and causing the leg support 14 to fall from the inner cavity of the seat body 1.

[0035] The working principle and usage process of the utility model are as follows: the air cylinder 2 is started to drive the piston plate 1 3 to move in the inner cavity of the air reservoir 4, thereby squeezing the air in the inner cavity of the air reservoir 4. The squeezed air enters the inner cavity of the piston cylinder 6 along the output pipe 5, thereby driving the piston plate 2 8 in the inner cavity of the piston cylinder 6 to rise and fall, and the air pressure in the inner cavity of the piston cylinder 6 is increased. When the piston plate 1 3 moves in the direction of the air cylinder 2, the air in the inner cavity of the piston cylinder 6 is extracted, thereby reducing the air pressure in the inner cavity of the piston cylinder 6.

[0036] Thereby adjusting the height of the seat body 1 at the top end of the piston cylinder 6. When bumps occur, the elasticity of the shock-absorbing spring 7 and the air pressure in the inner cavity of the piston cylinder 6 are used to reduce shock.

[0037] When the user's legs are long, the servo motor 12 can be started to drive the threaded rod 13 to rotate, and the rotation of the threaded rod 13 can drive the leg support plate 14 to move along the axial direction of the threaded rod 13 and the guide rod 15, so that the leg support plate 14 extends out of the inner cavity of the seat body 1, and then supports the user's legs through the leg support plate 14.
