Abstract

The invention discloses a kind of full automatic Sofa bed beds, and the present invention relates to field of furniture, the present invention makes the conversion between sofa and Simmons bed become simple and convenient, while ensuring sofa and the respective soft comfortable of Simmons bed.Present invention employs traditional mechanical drive modes, cleverly use two recombinations of four-bar mechanism, make the present invention when in use without artificially moving any object of the invention, full automatic to convert freely between sofa and Simmons bed.

Description

A kind of full automatic Sofa bed bed

Technical field

The present invention relates to field of furniture.

Background technique

In furniture industry without full automatic Sofa bed bed as the present invention, only see that a easy divan is It is full automatic, it is all easily manually to push and pull knockdown divan in industry, either that one kind is all that comparison is easy, nothing By being to use also extremely inconvenient when sofa or when bed is all without soft comfortable feeling, the present invention is solved from sofa The full-automation converted to Simmons bed, makes user's extremely simple convenience when in use, while existing as sofa and Simmons bed Individually also not a halfpenny the worse compared with their same type, thoroughly solving Sofa bed bed has soft comfortable impression.

Summary of the invention

The present invention is solved first using extremely succinct requirement, while making backboard 1 and seat board 2 all in soft suitable Degree, makes it have fabulous comfortable experience as the main body of sofa or Simmons bed, thus the Sofa bed in the present invention Bed pedestal 17 be it is fixed, the rear part can lean on wall (or object), be either collapsed into sofa and be still extended into Xi Meng Bed is thought, all without artificial lift, mobile any object of the invention.Present invention employs most basic mechanical drive modes, make The forward direction stretching, extension simultaneously of backboard 1 and seat board 2, when flattening, become Simmons bed, when backboard 1 and seat board 2 collapse After become sofa.For the effect of use feeling to sofa and Simmons bed, what backboard 1 of the invention and seat board 2 all designed It is very thick to meet this requirement.

Detailed description of the invention

Fig. 1 is the stereoscopic effect schematic diagram of full-automatic Sofa bed bed of the invention, and left hand view is to be collapsed into sand in Fig. 1 Stereoscopic effect when hair, right part of flg is to be extended into the stereoscopic effect of Simmons bed in Fig. 1.Fig. 2 is that the present invention removes right rear backplate 3, the structural schematic diagram after right apron plate 4, left back backplate 5, left front backplate 6, left hand view is structure when being collapsed into sofa in Fig. 2 Schematic diagram, right part of flg is structural schematic diagram when being extended into Simmons bed in Fig. 2.The label of each part is as follows in figure: 1 backrest It is oscillating rod behind plate, 2 seat boards, 3 right rear backplates, 4 right apron plates, 5 left back backplates, 6 left front shields, 7 oscillating rods, 8 connecting rods, 9,10 hinged Axis, 11 screw rods, 12 gear wheels, 13 pinion gears, 14 small machines, 15 motors, 16 cranks, 17 pedestals.

Specific embodiment

The present invention is explained in detail with reference to the accompanying drawing, referring to Fig. 2, present invention employs traditional machinery four Linkage makes sofa be extended into Simmons bed, and Simmons bed, which is collapsed into sofa, becomes freely simple, as can be seen from Figure 2 by song Handle 16, connecting rod 8, oscillating rod 7, pedestal 17 constitute four-bar mechanism, while backboard 1, oscillating rod 7, rear oscillating rod 9, pedestal 17 Also constitute four-bar mechanism.When motor 15 rotates clockwise, crank 16 is also rotated clockwise, then connecting rod 8 pulls oscillating rod 7 suitable Hour hands rotation；At this moment the clockwise motion of another set of four-bar mechanism oscillating rod 7 makes backboard 1 push rear oscillating rod 9 also up time Needle movement, when crank 16 is rotated clockwise to the position of Fig. 2 right part of flg, this two sets of four-bar mechanisms are completed from sofa to simmons The one-off of bed, backboard 1 are extended into horizontality.Backboard 1 is moved through from subvertical position to horizontal position Cheng Zhong, pushing seat board 2 to be omitted by the articulated shaft 10 between backboard 1 and seat board 2 has intilted position to move forward, Zhi Daoshui It is flat.Seat board 2 inwardly slightly has heeling condition in Fig. 2 left hand view, and at this moment the stabilization of its position is to drive pinion gear 13 by small machine 14, Gear wheel 12 drives screw rod 11 to be retractable to fixed position.When horizontal in Fig. 2 right part of flg seat board 2, also driven with small machine 14 13 gear wheel 12 of pinion gear makes screw rod 11 extend out to another fixed position to guarantee the firm level of seat board 2.When from Simmons bed When collapsing back sofa, Fig. 2 right part of flg is please referred to, 14 driving pinion of small machine, 13 gear wheel 12 first is retracted to screw rod 11 most Low position, 15 counterclockwise of motor drive 16 counterclockwise of crank, and until crank 16 and connecting rod 8 are in line, i.e. Fig. 2 is left The state of side figure, for backboard 1 to retract into state when sofa, backboard 1 passes through backrest during pulling back at this time Seat board 2 is also retracted into sofa state by the articulated shaft 10 between plate 1 and seat board 2, Fig. 2 left hand view state.At this moment Small machine 14 makes screw rod 11 reach fixed bit also by 13 gear wheel 12 of driving pinion.The present invention completes primary dynamic since then It recycles.The above is only an example of the present invention, for those skilled in the art, can there is various changes and change Change, all any modifications made within the principle of the present invention, equivalent replacement is improved, and protection scope of the present invention is all contained in It is interior.

Claims

1. a kind of full automatic Sofa bed bed, main feature is not necessarily to move any object of the invention when in use, leans on Backboard 1 and seat board 2 stretch forwards together, and flattening is at Simmons bed, and when gathering, backboard 1 drives seat board 2 together to pedestal 17 It is collapsed into the posture of sofa, is a kind of full automatic conversion posture mode.

2. the conversion between sofa according to claim 1 and Simmons bed is with traditional mechanical system, using four bars The expansion and gathering of sofa and Simmons bed are completed in two recombinations of mechanism under power drive.

3. four-bar mechanism is by oscillating rod 7, rear oscillating rod 9, backboard 1, pedestal in movement conversion according to claim 2 17 compositions, it is the conversion bodies for making backboard 1 between closely vertically and horizontally, connecting rod 8, crank 16, oscillating rod 7, pedestal 17 The four-bar mechanism of composition provides power, and guarantees two use state positions of the invention using two specific positions of four-bar mechanism The reliability and stability set.
