Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one: a kind of armchair, as depicted in figs. 1 and 2, including pedestal 1, positioned at 1 both sides of pedestal handrail 2 with
And the backrest 3 positioned at 1 rear side of pedestal, backrest 3 are rotationally connected with pedestal 1 close to the upper surface of rear side end.The back end surface of pedestal 1
It is fixed with horizontally disposed fixed plate 17, driving assembly 4 is installed in fixed plate 17, driving assembly 4 includes the first electricity
Machine 41, screw rod 42 and support plate 43.
First motor 41 is fixed on 17 upper surface of fixed plate and is obliquely installed, and screw rod 42 is fixed on the output of first motor 41
Axis, screw rod 42 are tilted along close to first motor 41 to the direction close to backrest 3 upwards.Support plate 43 is threadedly connected to screw rod 42,
Support plate 43 is welded with thin bar 18 far from the end of first motor 41, and end rotation connection of the thin bar 18 far from support plate 43 is limited
Position bar 6；Gag lever post 6 is cylinder, and gag lever post 6 connect that shape is at T-shaped with thin bar 18, and the trailing flank of backrest 3 is provided with from top to bottom
The limiting slot 5 in a strip shape being arranged, gag lever post 6 and the sliding of limiting slot 5 connect.
First motor 41 drives screw rod 42 to rotate, and the threaded connection of screw rod 42 and support plate 43 drives the inclination of support plate 43 to move
Dynamic, support plate 43 is along the direction linear motion close to or far from backrest 3；The cooperation of gag lever post 6 and limiting slot 5 is so that backrest simultaneously
3 rotate, gag lever post 6 and the opposite sliding of limiting slot 5.Under the driving of first motor 41, backrest 3 turns to proper angle, from
And the comfort level of rest is substantially increased with the rest of suitable posture on sofa convenient for the people of different building shape.
Gag lever post 6 and the cooperation of limiting slot 5 make support plate 43 be not easy to rotate with the rotation of screw rod 42, support plate 43
The track of linear movement is more stable, so that support plate 43 more quietly drives backrest 3 to rotate.Gag lever post 6 is rotationally connected with thin bar
18, when so that gag lever post 6 and limiting slot 5 sliding relatively, gag lever post 6 is rolled along the inner wall of limiting slot 5, thus by gag lever post 6
Sliding friction with limiting slot 5 becomes rolling friction, reduces the mobile suffered frictional resistance of gag lever post 6, makes the rotation of backrest 3 more
Be it is quick, reduce movement transmittance process in loss.
Screw rod 42 and support plate 43 have a self-locking performance, i.e., can only screw rod 42 drive support plate 43 to move linearly, support plate 43
Screw rod 42 cannot be driven to move, so that backrest 3 is fixed after carrying out angular adjustment, improve people's backrest 3 during the break
Stability.
Protective cover is fixedly installed in fixed plate 17, first motor 41 is located in protective cover, and screw rod 42 runs through protective cover.
Protective cover well protects first motor 41, and be not susceptible to first motor 41 is influenced and impaired by extraneous factor
Situation.
Total course of work: when needing to adjust the angle of backrest 3, first motor 41 drive screw rod 42 rotate, screw rod 42 with
The threaded connection of support plate 43 drives support plate 43 along inclined direction to move linearly, while gag lever post 6 and the cooperation of limiting slot 5 make
Backrest 3 is rotated around pedestal 1, and then the rotation of backrest 3 adjusts and arrives proper angle.
Embodiment two: a kind of armchair, as shown in Figure 3 and Figure 4, and the difference between this embodiment and the first embodiment lies in: it drives
Dynamic component 4 includes that the second motor 44, worm screw 45,46 gear 47 of worm gear and rack gear 48, the second motor 44 are fixed on fixed plate 17
Upper surface, worm screw 45 is fixed on the output shaft of the second motor 44 and horizontally disposed, and worm gear 46 is being located at worm screw 45 just
It top and is meshed with worm screw 45；Gear 47 and worm gear 46 are arranged in parallel and rotate synchronously with worm gear 46, gear 47 and worm gear 46
Between be fixed with shaft 16, the both ends of shaft 16 are individually fixed at the center of gear 47 and worm gear 46, thus gear 47 and snail
Wheel 46 rotates synchronously；Rack gear 48 is meshed with gear 47, and rack gear 48 arrives the direction close to backrest 3 to updip along close gear 47
Tiltedly.
As shown in Figure 4 and Figure 5, the upper surface of fixed plate 17 is mounted with the first strut 14 and the second strut 15, worm gear
46 and gear 47 be rotationally connected with the first strut 14 and the second strut 15 respectively.
The second protective cover 10 is fixedly installed in fixed plate 17, the second motor 44 is located in the second protective cover 10, thus the
Two motors 44 are well protected, and extend the service life of the second motor 44.Second protective cover 10 offers pilot hole 11, tooth
Item 48 is matched through pilot hole 11 and with pilot hole 11；The two sides of rack gear 48 offer the guide groove along 48 length direction of rack gear
13, the hole wall of pilot hole 11 is fixed with guide pad 12, and guide pad 12 and the sliding of guide groove 13 connect.
Rack gear 48 is provided with the connecting rod 9 being rotatablely connected with rack gear 48 close to the end of backrest 3, and the trailing flank of backrest 3 is provided with
Sliding slot 8 being arranged from top to bottom and in a strip shape, connecting rod 9 and the sliding of sliding slot 8 connect.
Second motor 44 drives worm screw 45 to rotate, and worm screw 45 drives worm gear 46 around 14 turns of the first strut with engaging for worm gear 46
Dynamic, worm gear 46 is rotated synchronously with moving gear 47 around the second strut 15 by shaft 16, and then gear 47 and rack gear 48 engage band
Carry-over bar 48 is tilted upward or is moved linearly diagonally downward；Connecting rod 9 is connect with the sliding of sliding slot 8 simultaneously rotates backrest 3, connecting rod
The 9 opposite slidings with sliding slot 8, to realize the transmitting of power, effectively easily the rotation of driving backrest 3 adjusts and arrives proper angle, makes one
Rest on sofa it is more comfortable.
The stability-of-path that the cooperation of guide pad 12 and guide groove 13 keeps rack gear 48 mobile, is leaned on so that rack gear 48 steadily drives
3 rotation of back.Connecting rod 9 and rack gear 48 are rotatablely connected so that connecting rod 9 along the chute 8 inner wall roll, by the sliding of connecting rod 9 and sliding slot 8
Friction becomes rolling friction, reduces the mobile frictional force of connecting rod 9, so that the rotation of 3 backrest 3 of backrest is more smooth quick, also subtracts
The energy consumption in driving 3 rotation process of backrest is lacked.
The lower end of second protective cover 10 and fixed plate 17 have a first through hole 19 and the second through-hole 20, rack gear 48 to
It may pass through first through hole 19 and the second through-hole 20 when lower inclination movement, and then keep the moving range of rack gear 48 bigger, thus rack gear
48 drive the angular range of the rotation of backrest 3 bigger, increase the scope of application of backrest 3.
Worm screw 45 and worm gear 46 have self-locking performance, i.e. worm screw 45 can only drive worm gear 46 to rotate, and worm gear 46 cannot drive snail
Bar 45 rotates, so that backrest 3 is not susceptible to shake when people is lain on backrest 3, improves fixed steady after the rotation of backrest 3 is adjusted
It is qualitative.
Above-described embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
