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
What the present invention relates to is a kind of door driving device, refers to a kind of transmission component of ventilation equipment especially.
Background technology
Traditional air door that is used for railcar can realize that damper blade evenly splits, and air-flow is smooth-going; But all be to adopt gear drive, processing cost height usually; Perhaps, suitable blade or the inhomogeneous leaf (driven by connecting rod influences) of splitting opened that drives by connecting rod arranged also, air-flow is inhomogeneous like this, and resistance is very big, directly has influence on air quantity and uniformity.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of transmission component to realize that throttle opening regulates automatically, and guarantee that each blade opening of air door is even, air-flow is smooth-going, and processing cost is reduced significantly.
Unresolved above-mentioned technical problem the invention discloses a kind of transmission component, and described door driving device comprises: an active rotation piece, and first end of described active rotation piece connects a power input shaft; A plurality of passive rotation pieces, first end of described passive rotation piece connects a power output shaft respectively, and second end of described passive rotation piece connects second end of described active rotation piece by a link assembly.
Of the present inventionly be that further described link assembly comprises a master connecting-rod and a plurality of slave connecting rod, described master connecting-rod connects second end of described active rotation piece and described passive rotation piece by described slave connecting rod.
The present invention drives the automatic unlatching of damper blade by this door driving device, can guarantee that each blade opening of air door is even, and air-flow is smooth-going, and processing cost is reduced significantly.
Description of drawings
Fig. 1 is applied to split the structural representation of leaf air door for door driving device of the present invention
Fig. 2 is the side schematic view of Fig. 1.
Fig. 3 is the action schematic diagram of door driving device of the present invention.
The specific embodiment
By reference to the accompanying drawings embodiments of the invention are elaborated in the example that is applied as of splitting on the leaf air door with door driving device of the present invention below; present embodiment is prerequisite with the technical solution of the present invention; provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Consult shown in Fig. 1～2, the leaf air door 1 of splitting of using door driving device of the present invention comprises a housing 10, plurality of vanes 20 and a motor 30, each blade 20 is arranged at the inboard of housing 10 in the mode of rotatable folding by a driving shaft 21 (being power input shaft and power output shaft), thereby motor 30 comes driven vane 20 to realize folding by door driving device 40 of the present invention, wherein door driving device 40 is mainly by a master connecting-rod 41, a plurality of moving blocks 42 and a plurality of connection master connecting-rod 41 are formed with the slave connecting rod 43 of moving block 42, wherein moving block 42 is further divided into active rotation piece and passive rotation piece, what adopt in the present embodiment is to be positioned at the moving block 42 at middle part as the active rotation piece, and 42 of remaining moving blocks are the passive rotation piece.The position of corresponding each blade 20, all be provided with a moving block 42 in the outside of housing 10, moving block 42 comprises one first end 421 and one second end 422, first end 421 of each moving block 42 connects the driving shaft 21 of its corresponding blade 20 respectively, wherein corresponding active rotation piece driving shaft 21 be power input shaft, the driving shaft 21 of corresponding passive rotation piece is power output shaft.Slave connecting rod 43 is arranged between two adjacent moving blocks 42, be used for connecting master connecting-rod 41 and moving block 42, it comprises one first end 431 and one second end 432, first end 431 of second end, the 422 auxiliary connection connecting rods 43 of a moving block 42 in the two adjacent moving blocks 42, second end 432 of second end, the 422 auxiliary connection connecting rods 43 of another moving block 42 in the two adjacent moving blocks 42, and second end 432 of this slave connecting rod 43 also connect with master connecting-rod 41 on.
Cooperate shown in Figure 3, use door driving device of the present invention split 1 work of leaf air door the time, at first drive driving shaft 21 rotations of the blade 20 that is positioned at the middle part by motor 30, this driving shaft can be considered as power input shaft 21 this moments, thereby it drives coupled active rotation piece 42 and rotates the 41 generation displacements up and down of driving master connecting-rod, and master connecting-rod 41 further rotates by slave connecting rod 43 remaining passive rotation piece 42 of drive, with any two adjacent moving blocks 42, because its second end 422 is connected to first end 431 and second end 432 of slave connecting rod 43, so when slave connecting rod 43 starts, second end 432 of adjacent two moving blocks 42 rightabout respectively rotates, and first end of final adjacent two moving blocks 42 drives adjacent two blades 20 and realizes splitting in twos.
