The first blade unit includes: two fixing bars 73, two

rectangular blades

81, 82 and a blade motor. The second blade unit includes: two fixing bars 74, two rectangular blades 83, 84 and a blade motor.

As shown in fig. 6, 7, and 8, taking the first blade unit of the end plate 31 as an example, the fixing rod 73 is located at the middle of the rectangular long ventilation holes 51 and 52 in the direction in which the wide sides extend. The extending direction of the fixing rod 73 is parallel to the extending direction of the long sides of the rectangular ventilation long holes 51, 52. Both ends of the fixing lever 73 are rotatably provided to the plate body 33. The second blade unit structure of the end plate 32 corresponds to the first blade unit structure of the end plate 31, and will not be described again.

As shown in fig. 6, 7, and 8, taking the first blade unit of the end plate 31 as an example, the

rectangular blades

81 and 82 are provided on the fixing rod 73, respectively. The longitudinal direction of the

rectangular blades

81, 82 is parallel to the extending direction of the fixing rod 73. The

rectangular vanes

81, 82 are capable of rotating from a first angle C1 to a second angle C2. When the

rectangular vanes

81 and 82 are rotated from the first angle C1 to a second angle C2, the opening of the long ventilation holes 51 and 52 can be extended in a direction gradually perpendicular to the square outer surface 30, so that the openings of the long ventilation holes 51 and 52 form a wind direction from an oblique direction to a direction perpendicular to the square outer surface 30.

As shown in FIG. 9, the vane motor output shaft 83 is connected to the fixed rod 73 by a worm gear drive and has a vane motor control end. When the output shaft 83 rotates, the fixed rod 73 can drive the blades to rotate from the first angle C1 to the second angle C2 through turbine transmission.

As shown in fig. 1 to 3, the speed sensor 91 is provided on the car side plate 20 and can acquire current speed information of the elevator car 10 traveling in the elevator shaft 90. The sensing output of the speed sensor 91 is connected to the input of the controller and is capable of outputting current speed information.

The control method of the low-noise elevator comprises the following steps:

as shown in fig. 4, when the input end receives the ascending driving information, the fan 34 on the plate 31 at the end of the ascending end 21 is turned on, so that the fan 34 at the ascending end 21 sucks the air in the elevator shaft 90 into the air storage chamber 35 at the ascending end 21, the vent holes of the ascending end 21 discharge the air outwards and an upper air curtain 71 is formed above the ascending end 21. The air in the air storage chamber 35 of the up end 21 enters the air storage chamber 35 of the down end 22 through the side passage 24 of the box side plate 20. The elongated vent holes in the down end 22 vent outwardly and form a lower air curtain 72 below the down end 22. Thereby making the elevator car more stable when ascending.

As shown in fig. 11, the current speed information of the speed sensor 91 is acquired, and it is determined whether the current speed information is within the first set speed, and if so, a first blade motor driving information is transmitted to the blade motor so that the blade is positioned at a first set angle C4 between the first angle C1 and the second angle C2. When the

rectangular vanes

81, 82 and the rectangular vanes 83, 84 are at the first set angle C4, they produce an air curtain having a shape like the arc of the upper and

lower air curtains

75, 76 in fig. 11.

Thereby when the elevator is in high-speed operation, make its air curtain face littleer, reduce the resistance of air curtain itself on the one hand, on the other hand because of the whole shape of air curtain is more concentrated on the car to strengthen the parcel dynamics to elevator car, make its elevator car's operation more steady.

As shown in fig. 4, if not, it is determined whether the current speed information is within the second set speed, and if so, a second vane motor driving information is transmitted to the vane motor such that the vane is located at a second set angle C3 between the first angle C1 and the second angle C2. The second set angle C3 is greater than the first set angle C4 with respect to the outer face 30. Which produces an air curtain shaped as the arc of the upper and

lower air curtains

71, 72 in figure 4. Thereby making the elevator car more stable when going downwards.

In another embodiment of the control method of a low noise elevator of the present invention, the method further includes: in another embodiment of a low noise elevator car 10 according to the present invention, as shown in fig. 5, when the input receives the downstream driving information, the fan 34 at the downstream end 22 is turned on so that the fan 34 at the downstream end 22 sucks air in the hoistway 90 into the air storage chamber 36 at the downstream end 22, and the air vents at the downstream end 22 discharge air to form a lower air curtain 72 below the downstream end 22.

The air in the air storage chamber 36 of the down end 22 enters the air storage chamber 34 of the up end 21 through the side passage 24 of the box side plate 20. The elongated vent holes in the upstream end 21 vent air outwardly and form a lower air curtain 71 above the upstream end 21. Thereby making the elevator car more stable when going downwards.

Therefore, the invention can automatically adjust the size of the air curtain, namely the size of the wrapping surface formed on the elevator car according to the running speed of the elevator car, so that the elevator car can run stably and safely at various speeds.
