Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to figs. 1 to a kind of control device for stability of automatic opening and closing of blower fan wind-guiding hinge shown in Fig. 5, including it is located at wind
A gangbar 1, the detent mechanism 3 of some swing arms 2 and one on casing body 5, described gangbar 1 are positioned at each wind-guiding hinge 4
The side position of rotating shaft 41 1 connecting rod；Described some swing arms 2 are the rotating shaft 41 that one end is fixedly connected on each wind-guiding hinge 4,
The other end is rotatably installed in the swing component in gangbar 2, and the swing component controls each wind-guiding hinge 4 same in the presence of gangbar 2
Walk rotating opening/closure back and forth；I.e. each swing arm 2 is the rotating shaft 41 that one end is fixedly connected on each wind-guiding hinge 4, the other end
The swing component in gangbar 2 is rotatably installed in, each swing component is used to control the synchronous rotating opening/closure back and forth of each wind-guiding hinge 4；
When described detent mechanism 3 is used for blower fan on/off, control wind-guiding hinge 4 automatically forms stable opening/closing state.
In embodiment, the inner or outer side of described Blower Housing 5 one is provided with a mounting groove 6, described gangbar 1, swings
Arm 2 and detent mechanism 3 are fixed on Blower Housing 5 by mounting groove 6.Described detent mechanism 3 is by tumbler 31 and pulls bullet
Spring 32 is constituted, and described tumbler 31, which is rotatably installed in, to be swung with wind-guiding hinge 4 on the side position of gangbar 1 one and rotate, this turn
The rotational angle of moving part 31 is that 30-90 °, the i.e. tumbler 31 rotate swing back and forth in 30-90 ° of angle.Described pulling spring 32 1
End is fixed in the peripheral position of tumbler 31, makes wind-guiding hinge 4 under blower fan on/off state during automatic opening/closing, is led to
Cross rotating shaft 41 and gangbar 1 drives tumbler 31 to rotate swing back and forth at an angle, the effect of spring 32 is being pulled during swing
It is lower to form each opening/closing positioning function of wind-guiding hinge 4.
Specifically, as shown in Figure 3 and Figure 4, described tumbler 31 is V-shaped component, the centre position of tumbler 31 leads to
Cross rotary shaft 311 and carry out location and installation, one end is rotatably connected on gangbar 1, and the other end passes through with pulling spring 32 to be connected installation
Tumbler 31 is formed when carrying out back rotation, relative stretching positioning function is realized.Further, the tumbler 31 is rotatably connected on
One end of gangbar 1 is actuating arm 312, and the other end is with pulling that spring 32 is connected for pull arm 313, and the pull arm 313 is in drawing
Move under the pulling of spring 32, positioned gangbar 1 by actuating arm 312, make the formation of each wind-guiding hinge 4 it is stable open/
Closure state.
Using when, when blower fan starts (i.e. electric motor starting rotation), blower fan wind-guiding hinge 4 slowly rotating opening, rotating opening
When by the rotating shaft 41 of wind-guiding hinge 4 to drive some swing arms 2 to control gangbar 1 to be swung up each wind-guiding hinge 4 of coordinated signals same
Step is slowly opened, while pulling actuating arm 312 to rotate when gangbar 1 is swung up, in rotary shaft when the actuating arm 312 is rotated
In the presence of 311, i.e., drive pull arm 313 to swing using rotary shaft 311 as central shaft, now, pull the progressively stress of spring 32
Stretching, when tumbler 31 turns to certain angle, (as shown in figure 5, the pull arm 313 of tumbler 31 is relative to pull spring 32
One end fixing point O and central line L of rotary shaft 311 is in -30 °), pull spring 32 to swing in the side of rotating shaft 311, that is, pull
When arm 313 is rotated clockwise, pulling spring 32, progressively stress is elongated, and is tensed tumbler 31 using pull arm 313, is rotated
The actuating arm 312 of part 31 keeps up gangbar 1 tension, wind-guiding hinge 4 is remained on automatically, even if linkage
Blower fan wind-guiding hinge 4 is positioned at open configuration by bar 1 by swing arm 2, it is to avoid wind-guiding hinge 4 is by sagging influence blower fan wind of conducting oneself with dignity
Power, that is, influence the dynamics blown outside blower fan wind direction；
Similarly, when blower fan closes (i.e. motor stalls), blower fan wind-guiding hinge 4 slowly rotates closing, when rotating closing
Some swing arms 2 are driven to control gangbar 1 synchronous to each wind-guiding hinge 4 of lower swing coordinated signals from the rotating shaft 41 of wind-guiding hinge 4
Slowly close, while gangbar 1 pulls actuating arm 312 to rotate to during lower swing, in rotary shaft 311 when the actuating arm 312 is rotated
In the presence of, i.e., drive pull arm 313 to swing using rotary shaft 311 as central shaft, now, pulling spring 32, progressively stress is turning
The opposite side of moving axis 311, i.e., when pull arm 313 is rotated counterclockwise, pulling spring 32, progressively stress is elongated, i.e. rotary shaft
311 form by the stretching of the stress of pulling spring 32 after opposite direction is swung, i.e., (as schemed when tumbler 31 turns to other direction angle
Shown in 4, the relative pulling one end fixing point O of the spring 32 and central line L of rotary shaft 311 of pull arm 313 of tumbler 31 is in
60 °), pull spring 32 to swing the opposite side in rotating shaft 311, tense tumbler 31 using pull arm 313, make the drive of tumbler 31
Swing arm 312 keeps down gangbar 1 tension, wind-guiding hinge 4 is kept closed automatically, even if gangbar 1 passes through
Blower fan wind-guiding hinge 4 is positioned at closure state by swing arm 2, makes to avoid wind-guiding hinge 4 from being influenceed performance by external wind, i.e.,
When having avoided general mood time, wind blows wind-guiding hinge 4 and rocks and trigger sound.
In order that wind-guiding hinge 4 is better achieved and automatically opens up performance, any wind-guiding hinge 4 in each wind-guiding hinge 4
Provided with starting provided with curved surface 43 is started in curved surface 43, i.e., the wherein wind-guiding hinge 4 in each wind-guiding hinge 4, the startup is bent
Face 43 is the arc extension for being located at the inboard side edge of wind-guiding hinge 4, the arc extension and the wind-engaging of adjacent wind-guiding hinge 4 formation one
Opening 44, the startup hinge for thus making this open all wind-guiding hinges 4 provided with the formation of wind-guiding hinge 4 for starting curved surface 43, works as wind
When machine starts, wind-engaging opening 44, the wind-guiding hinge where being automatically opened up in the presence of stress opening 44 are blowed to by blower fan wind-force
4, and all opened all wind-guiding hinges 4 by gangbar 1, the wind energy of blower fan is promptly opened all wind-guiding hinges 4, nothing
Power consumption control motor gear is needed to open or avoid using complicated, the centrifugal mechanism opening of working stability performance difference.
In order that each closing performance of wind-guiding hinge 4 is more preferably, described wind-guiding hinge 4 is provided with outer closed surface for outer side edges
45, inner side edge is provided with the wind deflector of interior closed surface 46, and the outer closed surface 45 is reversely corresponding laminating with interior closed surface 46
The curved surface of shape.
