Embodiment Construction

[0010] Taking the application of the damper driving device of the present invention on the split leaf damper as an example below, the embodiments of the present invention will be described in detail in conjunction with the accompanying drawings. The operation process, but the scope of protection of the present invention is not limited to the following examples.

[0011] refer to Figure 1~2 As shown, the split leaf damper 1 applying the damper driving device of the present invention includes a housing 10, a plurality of blades 20 and a motor 30, and each blade 20 passes through a drive shaft 21 (that is, a power input shaft and a power output shaft) to The rotatable opening and closing mode is arranged on the inner side of the housing 10, and the motor 30 drives the blade 20 through the damper driving device 40 of the present invention to realize opening and closing, wherein the damper driving device 40 is mainly composed of a main connecting rod 41, a plurality of rotating bl...

Abstract

The invention discloses a throttle driving device which comprises a drive rotating block and a plurality of driven rotating blocks; a first end of the drive rotating block is connected with a power input shaft; first ends of the driven rotating blocks are respectively connected with a power output shaft; and second ends of the driven rotating blocks are connected with a second end of the drive rotating block through a link assembly. Furthermore, the link assembly comprises a main link and a plurality of auxiliary links; and the main link is connected with the second end of the drive rotating block and the second ends of the driven rotating blocks through the auxiliary links. Throttle blades are driven to be automatically opened by the throttle driving device, the openings of the blades of the throttle can be guaranteed to be uniform, the air flows smoothly, and meanwhile, the processing cost is lowered considerably.

Description

technical field [0001] The invention relates to a damper driving device, especially a transmission assembly of ventilation equipment. Background technique [0002] The traditional dampers used in subway vehicles can realize the uniform opening of the damper blades and smooth airflow; but they are usually driven by gears, and the processing cost is high; or, there are also smooth-opening or unevenly-opening leaves driven by connecting rods ( Affected by the connecting rod drive), the airflow is uneven and the resistance is large, which directly affects the air volume and uniformity. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and provides a transmission assembly to realize the automatic adjustment of the opening of the air door, and ensure that the opening of each blade of the air door is uniform, the air flow is smooth, and the processing cost is greatly reduced. [0004] The above-mentioned technical...
