Two output shafts of the gearbox respectively transmit power to two speed reducers, the two speed reducers are opposite, namely the speed reducer of the air door on one side is a forward speed reducer, the speed reducer on the other side is a reverse speed reducer, and the power of the speed reducers is transmitted to the driving gear to enable the driving gear to rotate.
The meshing of drive gear is equipped with the arc rack, the arc rack is the curved shape rack form that one side has tooth, and it has tooth one side and drive gear meshing. Each driving gear is meshed with two arc-shaped racks, one tooth of each arc-shaped rack is positioned outside the curved surface, and the other tooth of each arc-shaped rack is positioned inside the curved surface. One end of each arc-shaped rack is hinged with the inner surface of the corresponding air door.
And each arc-shaped rack is independently tensioned by a hydraulic tensioning device so as to ensure the motion track of the arc-shaped rack.
Furthermore, the power mechanism adopts a double-power mode and is provided with standby power.
Further, the standby power setting mode is as follows: the motor is characterized in that a chain wheel A is arranged on an output shaft of the motor, a pneumatic motor can be used as standby power, a chain wheel B is arranged on an output shaft of the pneumatic motor, and the chain wheel A is connected with the chain wheel B through a chain. When the motor is damaged, the pneumatic motor can be started to output power.
Furthermore, two output shafts of the gearbox are respectively connected with a worm gear transmission mechanism through a coupler to transmit power to two speed reducers, and the speed reducers transmit the power to the driving gear. The specific arrangement mode of the worm gear is mature prior art, and is not described in detail here.
The utility model discloses during the use, driving motor or pneumatic motor drive the gearbox, and the dual output axle of gearbox is synchronous with power transmission to two speed reducers, and two speed reducers are with power transmission to two drive gear, and two drive gear control two air doors respectively, that is to say, when drive gear rotates, and the arc rack rather than the meshing is rotatory because hydraulic tensioning device's effect, along certain orbit, drives the air door at rotatory in-process and realizes the switching. And because the two driving gears synchronously rotate and the rotation directions are opposite, the four air doors arranged oppositely can be controlled to be opened or closed simultaneously.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use adopts same power supply and synchronous power transmission structure when the air door switching, has realized opening and closing when subtend air door, very big improvement application safety factor. And, through the setting of reserve power, guaranteed the steady operation of air door, make its operation safer firm.

Detailed Description
Referring to fig. 1 and 2, the utility model discloses a two door single gear centralized control to open air door, including power unit, drive mechanism and air door main part.
The power mechanism can adopt a motor 9, and the motor 9 drives a transmission mechanism to control the air door 2 to be opened and closed simultaneously. The main body of the air door 2 is a split inward closing air door in the prior art.
The transmission mechanism is arranged in the following form: the output shaft of the motor 9 is connected with a gearbox 7, and the gearbox 7 is a double-output-shaft gearbox so as to ensure the synchronization of two-way output power.
Two output shafts of the gearbox 7 respectively transmit power to the two speed reducers 5, the two speed reducers 5 are opposite, namely the speed reducer 5 of the air door on one side is a forward speed reducer, the speed reducer on the other side is a reverse speed reducer, and the power of the speed reducer 5 is transmitted to the driving gear 4, so that the driving gear 4 rotates.
