Background technology
Existing beddo includes bed frame and lower bedstead mostly in the market, wherein, the bed that can be overturn relative to bedstead
Plate or bed frame are arranged in bed frame, and the drivings, that is, interlinked mechanism such as motor and connecting rod is arranged in lower bedstead.Due to bunk bed
Frame, which is respectively provided with thickness, motor and push rod, can have enough power when turnover bed board or bed frame are risen from initial position
Square.
However, such structure so that the thickness of beddo is larger, the aesthetics of beddo and light degree are affected, it is uncomfortable
For Ultrathin electric bed.
And if simply reduce bedstead thickness, then the problem of initial torque being caused inadequate.
Utility model content
To solve the above problems, the utility model provides a kind of mechanism for lifting back for beddo, with push rod
Group, outer fixed frame, interior sliding frame and back frame, wherein, interior sliding frame slides in the horizontal plane with outer fixed frame
Connection, back frame are pivotally connected with interior sliding frame and can rotate relative to interior sliding frame and be slided relative to outer fixed frame
Dynamic, push rod group includes short push rod and long push rod, and one end and the back frame of short push rod are pivotally connected, the other end and outer fixed frame pivot
It connects, one end and the back frame of long push rod are pivotally connected, and the other end is pivotally connected relative to outer fixed frame；
During back frame rises, push rod group has two-part stroke：
In first segment stroke, the relatively outer fixed frame of interior sliding frame slides, and to push back frame, and causes short
Push rod acts on back frame and it is made to rise a smaller angle beyond institute's plane, back frame is not produced with duration push rod
Raw impetus；
In second segment stroke, the relatively outer fixed frame of interior sliding frame continues to slide, further to push back frame
Frame, and long push rod is caused to act on back frame and it is made further to rise, while short push rod does not generate promotion to back frame
Effect.
The mechanism for lifting back of the utility model also has one or more of feature：
Further, the slip of the relatively outer fixed frame of interior sliding frame is driven by push-rod electric machine.
Further, there is the fixing end of long push rod and outer fixed frame one section of free travel to be configured, in order in the first row
Cheng Zhong, long push rod do not generate impetus to back frame.
Further, free travel is configured to be arranged on outer fixed frame one section of sliding slot and is arranged on the one of long push rod
The sliding block at end, wherein sliding block can slide in sliding slot.
Further, on sliding block there is axle sleeve, the friction between sliding block and sliding slot can be reduced and sent out when reducing friction
Noise, it is preferable that sliding sleeve is made of plastics.
Further, short push rod is made of pipe and sleeve, in order to have free travel in second segment stroke without right
Back frame generates impetus, and when back frame is raised to maximum angle, the pipe of short push rod is not detached with sleeve.
Optionally, short push rod is coaxially pivotally connected with long push rod with back frame.
Optionally, short push rod is non-coaxially pivotally connected with long push rod with back frame respectively.
Further, in the first segment stroke of two-part stroke, the angle between short push rod and outer fixed frame is gradual
Become larger, short push rod reaches upright position when short push rod is perpendicular to outer fixed frame, to prevent short push rod more than upright position
After continue to back frame apply thrust and back frame is caused to decline, short push rod reach upright position before, two-part row
The second segment stroke of journey starts to act on.
Another of the utility model is designed to provide a kind of beddo, including above-described lifting back machine
Structure.
The utility model proposes mechanism for lifting back by the way that upper and lower bedstead is converted to internal and external frame, so as to reduce electricity
The thickness of dynamic bed structure, further through the combination of short push rod and long push rod, using two-part stroke, in relatively thin bedstead space,
The initial torque for rising back frame is provided and continues the torque risen, the bedstead of beddo is too thick to ask so as to solve
Topic, while also solve the problems, such as that Ultrathin electric bed initial torque is insufficient.

One section of sliding slot on long push rod.
As variant, the configuration of the free travel of long push rod also be able to be long push rod one section of distance of stretch out and draw back.Fig. 5 to Fig. 7 is
The local perspective view of beddo with above-mentioned mechanism for lifting back.Wherein, in Figure 5, mechanism for lifting back is in initial bit
It puts；In figure 6, mechanism for lifting back is in the critical localisation converted from first segment stroke to second segment stroke；In the figure 7, it carries on the back
Portion's mechanism for lifting is in the extreme higher position of second segment stroke.
In this embodiment, beddo has outer bedstead and interior bedstead, instead of bed frame of the prior art and leaves the bed
Frame so as to reduce the thickness of bedstead structure, further also has above-mentioned mechanism for lifting back.
Wherein, the outer fixed frame 1 in mechanism for lifting back is a part for outer bedstead, and interior slip bedstead 2 is interior bedstead
A part.
Further, beddo has push-rod electric machine 6, for interior bedstead to be driven to be slided relative to outer bedstead.
Further, beddo also is able to set bed board or package flexible material in the back frame of mechanism for lifting back.
Above example to the scope of the utility model only as an example, do not play restriction effect.Those skilled in the art
It on this basis, can be in the protection domain of the utility model claims, it is contemplated that the other realities that can realize identical function
Apply mode.For example, sliding slot and sliding block can be substituted by other well known form, axle sleeve can be by other material systems for meeting performance requirement
Into.
