Blinds driving device 100 according to an embodiment of the present invention is described below with reference to Fig. 1-Fig. 6.
As shown in figs 1 to 6, blinds driving device 100 according to an embodiment of the invention includes: fixing seat 10, can revolve
Gear 30, moveable rack gear 20 and the driver 40 turned.
Fixing seat 10 has rack gear mounting portion 11, gear mounting portion 12, and gear 30 is arranged on gear mounting portion 12, rack gear
20 are arranged on rack gear mounting portion 11, and rack gear 20 and gear 30 are sequentially connected, and rack gear 20 is connect with the connecting rod 50 of blinds 60, drive
Dynamic device 40 is connect with gear 30, and driver 40 is used to that gear 30 to be driven to rotate, and then with carry-over bar 20, connecting rod 50 and blinds 60
Activity.
Wherein, rack gear mounting portion 11 limits hollow channel 111, and hollow channel 111 extends along the length direction of rack gear 20,
A part of rack gear 20 is plugged in hollow channel 111, and can be along 111 activity of hollow channel, when improving the movement of rack gear 20
Stability.
Blinds driving device 100 according to an embodiment of the present invention, by the way that the mounting portion of each structure is arranged in fixing seat 10,
So that blinds driving device 100 realizes Integrated design, the assembly efficiency and operational reliability of blinds driving device 100 are improved；
Cooperate driving blinds 60 to move by 30 rack gear 20 of gear, increases the motion amplitude of blinds 60, and stable drive, stress are equal
Even, the movement velocity of blinds 60 is uniform；It is movable in hollow channel 111 by the cooperation of rack gear 20, further improve blinds 60
Stability when movement efficiently solves the problems, such as 60 fluctuation of service of blinds, shake in the prior art；And blinds driving dress
It is simple to set 100 structures, is easily installed and dismounts, it can be with wide popularization and application.
According to one embodiment of present invention, (as shown in Figure 1 is upper along the length direction of hollow channel 111 for connecting rod 50
Lower direction) be disposed to extend, connecting rod 50 is located at the upper end of fixing seat 10, from the top down, the cross-sectional area of hollow channel 111 by
It is decrescence small, to make the cross-sectional area of one end of the close connecting rod 50 of hollow channel 111 greater than the cross section face of the other end
Product, activity of the rack gear 20 in hollow channel 111 are limited by hollow channel 111, and rack gear 20 is made to be only capable of passing through hollow channel
111 a part prevents 20 scope of activities of rack gear excessive and is detached from hollow channel 111.
Meanwhile along the length direction of hollow channel 111, the cross-sectional area of hollow channel 111 is gradually reduced, so that hollow
Channel 111 forms pyramid, is conducive to the depanning of mold in manufacturing process, convenient for being manufactured.
In a specific example, 111 side's of being formed annular of hollow channel, at least one wall surface shape of hollow channel 111
At inclined-plane, along the length direction of hollow channel 111, on the direction from close to connecting rod 50 to far from connecting rod 50, the inclined-plane by
Gradually extend to the center of hollow channel 111, for example, as shown in figure 4, the wall surface in the left side of hollow channel 111 from top to bottom, gradually to
Right bank extends, and the wall surface on 111 right side of hollow channel is from top to bottom, and be gradually tilted to the left extension, for another example hollow channel
The wall surface of 111 front sides from top to bottom, gradually tilts backwards extensions, the wall surface on rear side of hollow channel 111 from top to bottom, gradually forward
Inclination extends, so that the cross-sectional area of one end of the close connecting rod 50 of hollow channel 111 is greater than hollow channel 111 separately
The cross-sectional area of one end.
As shown in figure 4, according to one embodiment of present invention, the wall surface of hollow channel 111 is equipped with retaining convex rib 112, limit
Position convex ribs 112 extend along the length direction of hollow channel 111, i.e., extend along the vertical direction, retaining convex rib 112 and hollow channel
111 tilted wall surfaces have certain angle, so that the inclined wall surface of hollow channel 111 does not influence the activity of rack gear；And
When rack gear 20 slides, rack gear 20 is only against on retaining convex rib 112, so that rack gear 20 is always along line activities, without occurring
Shaking or play.
As shown in figure 4,111 side's of being formed annular of hollow channel, hollow channel 111 is at least in a specific example
A part of wall surface forms closed ring wall surface, has multiple retaining convex ribs 112, multiple retaining convex ribs 112 in hollow channel 111
Along the circumferentially-spaced arrangement of the ring wall surface of hollow channel 111, when rack gear 20 slides, multiple retaining convex ribs 112 are and rack gear
20 only support, and further avoid rack gear 20 and shake in hollow channel 111 or play.
As shown in Figure 1, according to one embodiment of present invention, rack gear 20 includes sliding part 21 and rack gear ontology 22, rack gear
Ontology 22 is arranged on sliding part 21, and sliding part 21 is suitable for cooperating with the retaining convex rib 112 in hollow channel 111, thus in
Sliding in empty channel 111, and slided with carry-over bar ontology 22, rack gear ontology 22 is always positioned in hollow channel 111, and not in
The wall in empty channel 111 contacts, and rack gear ontology 22 is suitable for cooperating with gear 30, and under the driving of gear 30, drives sliding part 21
It is slided in hollow channel 111, the setting of sliding part 21 can make rack gear ontology 22 and the cooperation of gear 30 more smooth, simultaneously
It avoids rack gear ontology 22 from shaking in hollow channel 111 or play, and by the Design of length to rack gear ontology 22, makes to connect
The operation amplitude of extension bar 50 and blinds 60 gets a promotion, and improves air output and outlet air efficiency.
As shown in figure 4, in some instances, rack gear mounting portion 11 includes guide section 1101 and linkage section 1102, guide section
1101 mutually fasten and limit hollow channel 111 with linkage section 1102, and guide section 1101 is for constraining sliding part 21, linkage section
1102 for constraining rack gear ontology 22, and linkage section 1102 is located at the side of the close gear mounting portion 12 of guide section 1101, so as to
In the cooperation of rack gear ontology 22 and gear 30.
Wherein, width of the width of guide section 1101 greater than linkage section 1102, the width of guide section 1101 referred herein,
I.e. shown in Fig. 4, along the longitudinal direction, the distance between two opposite side walls of guide section 1101, the width of linkage section 1102
It is two opposite the distance between side walls of linkage section 1102, by the way that guide section 1101 and linkage section 1102 are limited size
Different width, so as to form limited step 113 in the wall surface of hollow channel 111, limited step 113 can be to sliding part
21 and rack gear ontology 22 play restriction effect, be always positioned at sliding part 21 in guide section 1101, avoid sliding part 21 tilt shadow
Ring the activity of rack gear ontology 22.
As shown in Figures 2 and 3, according to one embodiment of present invention, gear mounting portion 12 is arranged in rack gear mounting portion 11
Side, rack gear mounting portion 11 has an escape port 114, escape port 114 can by hollow channel 111 and it is extraneous be connected to, gear 30
It is positioned adjacent to the position of escape port 114, so as to be sequentially connected by escape port 114 and rack gear 20, and blinds can be made
The overall structure of driving device 100 is more compact, rationally distributed, reduces volume, improves the utilization rate in space.
