Summary of the invention
The purpose of this utility model is to provide a kind of novel changable shape divan, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of novel changable shape divan, comprise underframe, cushion, backrest, first connecting rod, second connecting rod, fixed support and sliding support, parallel on described fixed support many directive slide tracks are installed, described sliding support is provided with multiple slide block coordinated with directive slide track, described slide block forms sliding pair along the axial sliding movement of directive slide track; Described fixed support is fixedly mounted on underframe top, described sliding support is fixedly mounted on cushion bottom, described first connecting rod is fixedly mounted on backrest by bearing pin, described first connecting rod is movably connected on sliding support by the first bearing pin, first connecting rod and sliding support with the axis of the first bearing pin for axle is formed rotary pair; Described second connecting rod is fixedly mounted on fixed support by the second bearing pin, and described first connecting rod is flexibly connected by the 3rd bearing pin with between second connecting rod, first connecting rod and second connecting rod with the axis of the 3rd bearing pin for axle is formed rotary pair.
As further program of the utility model: the relative sliding distance between described cushion and underframe is 0-0.6m, and the movable angle of described cushion and backrest is 90-180 °.
As further program of the utility model: described directive slide track adopts round bar, square pole or rectangular shaft.
As the utility model further scheme: the sliding motion of described fixed support and sliding support adopts linear electric motors to drive to be out of shape, air cylinder driven manual deformation or hydraulic oil cylinder driving manual deformation.
Compared with prior art, the beneficial effects of the utility model are:
1, divan of the present invention can realize the function of sofa, realizes again the function of bed by distortion; Divan can lean on wall and place, and by Its Track Design dexterously, when functional mapping, without the need to mobile sofa position, functional mapping is very convenient, solves the difficult problem that function sofa of passing on Gong cannot fall by wall rear backrest;
2, divan of the present invention by linkage dexterously practical function conversion, when being transformed to sofa function, part cushion be hidden with backrest under, reduce sofa spatial volume; When being transformed to a bed function, cushion and backrest stretch respectively to both sides, and the cushion making originally to be hidden under backrest can launch completely, considerably increases the area of bed under the prerequisite that sofa is constant to space hold amount;
3, the backrest of divan of the present invention can free adjustment inclination angle, meets the demand of different sitting posture;
4, the linkage structure of divan of the present invention is relatively independent, does not rely on the installation site of sofa backrest and cushion, greatly simplifies the assembling difficult problem in manufacturing process, improving product functional stabilization greatly.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of novel changable shape divan, comprises underframe 1, cushion 2, backrest 3, first connecting rod 4, second connecting rod 5, fixed support 6 and sliding support 7.
As Fig. 2, parallel on fixed support 6 many directive slide tracks 9 are installed, sliding support 7 is provided with multiple slide block 8 coordinated with directive slide track 9, slide block 8 forms sliding pair along the axial sliding movement of directive slide track 9, realizes the linear relative movement of fixed support 6 and sliding support 7.
As Fig. 2, Fig. 3, fixed support 6 is relative with underframe 1 to be fixedly mounted, and sliding support 7 is relative with cushion 2 to be fixedly mounted, and first connecting rod 4 fixedly mounts by bearing pin 13 is relative with backrest 3; First connecting rod 4 is connected by the first bearing pin 10 with sliding support 7, and with the axis of the first bearing pin 10 for axle is formed rotary pair; Second connecting rod 5 is connected by the second bearing pin 11 with fixed support 6, and with the axis of the second bearing pin 11 for axle is formed rotary pair; First connecting rod 4 is connected by the 3rd bearing pin 12 with second connecting rod 5, and with the axis of the 3rd bearing pin 12 for axle is formed rotary pair.
As Fig. 3, Fig. 4, first connecting rod 4, second connecting rod 5, fixed support 6, sliding support 7 form a crank block bar linkage motion mechanism by above-mentioned annexation, by the straight line sliding motion of slide block 8 with directive slide track 9, realize cushion 2 to slide with the relative rectilinear of underframe 1, realize backrest 3 to change with the relative position of cushion 2 simultaneously, make cushion 2 and backrest 3 adjustable angle.
Bar linkage motion mechanism has complete independently motion deformation function, namely the assembly relation of first connecting rod 4, second connecting rod 5, fixed support 6, sliding support 7 determines the movement locus of divan, do not rely on the installation site of underframe 1, cushion 2 and backrest 3, thus guarantee divan functional stabilization, simplify and manufacture assembly difficulty.
Usually, cushion 2 and underframe 1 relative sliding distance b freely can change between 0-0.6m, and the angle of cushion 2 and backrest 3 freely can change between 90-180 °.
Directive slide track 9 can be round bar, also can be square pole or rectangular shaft.
Fixed support 6 can be driven by linear electric motors with the sliding motion of sliding support 7, and realize the distortion of divan electric drive, i.e. electronic shape changeable sofa bed, also can carry out manual deformation by cylinder or oil cylinder.
Electric sofa bed is when being out of shape, and no matter how backrest 3 changes relative to the inclination angle of cushion 2, and the outer of backrest 3 does not all surmount the border of underframe 1, and therefore divan is when functional mapping, can place, without the need to moving position by parados all the time.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
