Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the utility model provide the flexible frame for seat unit, include fixation bottom bar, The front support rod 2 rotating in perpendicular and back support rod 3, located at back and front supporting masthead portion and the seating pad 4 that is connected and backrest Plate 5 and footstool assembly.
The bottom of front support rod 2 is articulated with the front end of bottom bar 1, and the top of front support rod 2 is articulated with footstool assembly;Rear support The bottom of bar 3 is articulated with the rear portion of bottom bar 1, and the top of back support rod 3 is connected to the rear end of seating pad 4 by first connecting rod 6, sits The top of the rear end of backing plate 4 and back support rod 3 is respectively equipped with the first driving section 41 cooperating and the second driving section 31.Bottom bar 1 front end refers to bottom bar one end away from backboard 5, and the rear portion of bottom bar 1 refers to bottom bar towards the side of backboard 5.
As shown in figure 3, first and second driving section 41,31, all in fan-shaped, the arc outer wall of the first driving section 41 is uniformly provided with Some driving tooths 42, the arc outer wall of the second driving section 31 is uniformly provided with some driven tooth 32 being engaged with driving tooth.First Driving section 41 is provided with the first deep-slotted chip breaker 43 that the center of circle is overlapped with the fan-shaped center of circle of the first driving section, and first connecting rod 6 is fixed with With the first pin 61 of the first deep-slotted chip breaker cooperation, the first pin is in the first deep-slotted chip breaker.Second driving section 31 is provided with the center of circle The second deep-slotted chip breaker 33 being overlapped with the fan-shaped center of circle of the second driving section 31, first connecting rod 6 is fixed with and is joined with the second deep-slotted chip breaker 33 The second pin 62 closing, the second pin 62 is located in the second deep-slotted chip breaker 33.
In the present embodiment, first connecting rod 6 is provided with the connecting portion 63 of backboard 5 extension, i.e. first in the present embodiment Connecting rod 6 is L-shaped, that is, rectangular at first connecting rod turning point.One end of first connecting rod 6 is articulated with the fan-shaped circle of the second driving section 31 At the heart, the right angle of first connecting rod 6 is articulated with the fan-shaped circle centre position of the first driving section 41 by pin 64.For seat unit Flexible frame also includes the second connecting rod 7 for connecting first connecting rod 6 and backboard 5, and one end of second connecting rod 7 is articulated with connection The end in portion 63, second connecting rod 7 other end is articulated with the bottom of backboard 5, and the end of connecting portion 63 refers to connecting portion away from first The end of connecting rod 6.In order to beneficial to transmission, the top of seating pad 4 is articulated with the substantially middle part of backboard.
Footstool assembly includes drive link 84, the first pole 81, the second pole 82, front stool couch connecting rod 83 and puts footstool couch 85, the top of drive link 84 is articulated with the front end of seating pad 4, and the bottom of drive link is articulated with one end of the second pole 82, The other end of the second pole is articulated with puts footstool couch 85;The top of front stool couch connecting rod 83 is articulated with the front portion of seating pad 4, first One end of bar 81 is articulated with the bottom of front stool couch connecting rod 83, and the other end of the first pole 81 is articulated with puts footstool couch 85, the company of driving The bottom of bar 84 is hinged with the substantially middle part of the first pole 81;The top of front support rod 2 is hinged with front stool couch connecting rod 83.
The first spacer pin 91 for spacing footstool component movement stroke, current stool couch connecting rod 83 are fixed with seating pad 4 When moving to circumscribed with the first spacer pin 91, footstool component movement is to maximum extension state.
The second spacer pin 92 for spacing front support rod 2 rotation path is further fixed on seating pad 4, front support rod 2 Top is provided with arc groove 21 for avoiding the second spacer pin 92 and cooperation circumscribed with the second spacer pin and curved spacing Wall 22.The top of front stool couch connecting rod 83 is provided with the locking groove with the second spacer pin 91 cooperation, and current stool couch link motion is to stop When groove and the second spacing pin contacts, leg rest board component returns back to rounding state.
Drive link 84 is the overall power rail of frame, and during the utility model application, cooperation motor uses, i.e. telescope motor Realize the overall gathering of frame and expansion action by driving drive link 84 motion.
When flexible frame entirety is when shown in Fig. 1, rounding state moves to the first deployed condition shown in Fig. 4, telescope motor band Dynamic footstool assembly rotates counterclockwise makes footstool assembly launch, i.e. drive link 84, the first pole 81, the second pole 82, front stool couch Connecting rod 83 and put footstool couch and be all rotated up counterclockwise.Current stool couch connecting rod 83 is moved to when being contacted with the first spacer pin 91, pin To extended configuration, now, the second spacer pin 92 completely disengages from the arc groove 21 at front support rod 21 top to stool component movement.
Seating pad 4 rotates clockwise certain angle in this motion process, is made by the engagement of driving tooth 42, driven tooth 32 With driving back support rod 3 to rotate counterclockwise certain angle.Meanwhile, backrest is driven by the effect of first connecting rod 6 and second connecting rod 7 Plate 5 rotates counterclockwise certain angle, so that backboard 5 tilts backwards.
Telescope motor continuation effect makes flexible frame move to the second expansion shown in Fig. 5 from the first deployed condition shown in Fig. 4 During state, telescope motor continues to act on drive link 84, because front stool couch connecting rod 83 is limited by the first spacer pin 91, pin Stool assembly can not rotate.The active force of telescope motor extends to seating pad 4, and telescope motor drives seating pad 4 to move forward, cushion Back support rod 3 is driven to be clockwise to deviation vertical direction certain angle when plate moves forward.Meanwhile, back support rod 3 passes through First connecting rod 6 and second connecting rod 7 drive backboard 5 to rotate down counterclockwise.When the first pin 61 touches the first deep-slotted chip breaker 42 Inwall when, seating pad 4 and backboard 5 are expanded to greatest limit position.In this stretching process, front support rod 2 is along along pointer Turn to deviation vertical direction certain angle, when seating pad 4 and backboard 5 are expanded to greatest limit position, front support rod Limited wall 22 is close to the second spacer pin 92.
When flexible frame is from state reset shown in Fig. 5 to state shown in Fig. 1, telescope motor acts on drive link 84, Because the limited wall 22 of front support rod 2 is against on the second spacer pin 92, footstool assembly can not rotate.The active force of telescope motor prolongs Extend after seating pad 4 makes seating pad and move, meanwhile, front support rod 2 and back support rod 3 rotate counterclockwise up to front support rod 2 top Limited wall 22 completely disengage from the second spacer pin 92, meanwhile, backboard 5 is driven by the effect of first connecting rod 6 and second connecting rod 7 Rotate clockwise reset.Telescope motor continues to retract, and drives footstool assembly multiple along rotating clockwise gathering by drive link 84 Position.When current stool couch connecting rod 83 is turned to locking groove and contacted with the second spacer pin 92, footstool assembly is reset to rounding state.Stretching During contracting motor continues to retract, seating pad 4 and backboard rotate clockwise certain angle.
The utility model embodiment additionally provides a kind of seat unit, including two parallel and the telescopic machine of mirror image setting Frame, flexible frame is above-mentioned flexible frame.
In addition to above preferred embodiment, the utility model also has other embodiments, and those skilled in the art can root It is variously modified according to the utility model and deforms, without departing from spirit of the present utility model, the utility model all should be belonged to Scope as defined in the claims.
