Specific embodiment
In order to which the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached
The utility model is further described in figure.
Shown in referring to Fig.1~4, the single motor beddo of the utility model, including under(-)chassis 9, linear electric machine 5, lever
Formula mechanism 1, back plate 6, buttocks and legs plate 7 and calf plate 8, between each section of under(-)chassis 9 and under(-)chassis 9 and other parts
Between can be connected by removably, such as be threadedly coupled etc..
As shown, under(-)chassis 9 includes bottom framework 901 and motor support frame 902, back support 903 and small
Leg support 904, bottom framework 901 is along horizontally arranged, motor support frame 902, back support 903 and leg support
904 arranged for interval of frame is in bottom framework 901 and each along longitudinal extension, motor support frame 902, back support 903 and small
Leg support 904 is sequentially arranged along the left and right directions in figure, and adjacent is a part of by constituting bottom framework 901 between the two
Connecting tube 905 connect.
Lever mechanism 1 includes the arm bar 101 and transmission rod 102 being hinged, one end of arm bar 101 and transmission rod
102 is hinged, and the other end and bottom framework 901 of arm bar 101 are hinged;One end of transmission rod 102 and arm bar 101 are hinged, pass
The other end of power bar 102 and back plate 6 are hinged, linear electric machine 5 be articulated with motor support frame 902 lower part and arm bar 101 or
Between transmission rod 102, linear electric machine 5 can linear movement output, linear electric machine 5 act when, can drive arm bar 101 with
Transmission rod 102 mutually rotates, so that power is transferred to back plate 6.
Back plate 6 is also articulated on back support 903, and buttocks and legs plate 7 is connect with back plate 6 by first axle mechanism 3,
Calf plate 8 is connect with buttocks and legs plate 7 by second hinge mechanism 4, at least one in first axle mechanism 3 and second hinge mechanism 4
For the mobile linkage that can be stretched, calf plate 8 is fixed on leg support frame 904.Preferably, the back side of back plate 6
It is provided with back frame 2, transmission rod 102 and back support 903 are hinged with back frame 2.
In conjunction with shown in Fig. 3, Fig. 4, back support 903 is located at side of the arm bar 101 far from motor support frame 902,
Constitute the center of rotation of back plate 6.Under the present embodiment, first axle mechanism 3 is mobile linkage, second hinge mechanism
4 be solid joint mechanism.The movable type linkage, refers between two bars for constituting hinge in addition to that can relatively rotate
Except, it can also relatively move, such as shown in the figure, first axle mechanism 3 includes the first rod piece 301 and the second rod piece 302, the
One rod piece 301 is fixed on back plate 6, and the second rod piece 302 is fixed on buttocks and legs plate 7, offers kidney slot 303 on the second rod piece 302,
Pin shaft (not indicating in figure) is arranged in the end of first rod piece 301, which is arranged in the kidney slot 303, in this way, just can be realized
The function of rotation and the relative movement of first rod piece 301 and the second rod piece 302.Solid joint mechanism refers to composition hinge
It is only capable of relatively rotating between two rod pieces of mechanism, and cannot relatively move.Such as it is as shown in the figure, second hinge mechanism 4 is only capable of
Enough realize rotating function.
First rod piece 301 and the second rod piece 302 can by relatively rotating and move, increase back plate 6 and buttocks and legs plate 7 it
Between distance, on the one hand alleviate back plate 6 and buttocks and legs plate 7 to the pressure of human abdomen, achieve the effect that pressure discharges, it is another
Aspect due to calf plate 8 be it is fixed, can make buttocks and legs plate 7 rotate, therefore buttocks and legs plate 7 can tilt down with calf plate 8 at
Certain angle, such lifting back, buttocks decline are equivalent to calf and are lifted.
Further, the length of arm bar 101 is greater than the length of transmission rod 102, and linear electric machine 5 is articulated with arm bar 101
End far from bottom framework 901, transmission rod 102 are articulated with arm bar 101 close to the position of linear electric machine 5, in this way, being convenient for line
Property motor 5 power transmitting, guarantee leverage effects.
Control unit can be further arranged in the beddo of the utility model, and remote controler is arranged, to realize remote control.
The working principle of the utility model are as follows: it is released when bed surface is parallel by linear electric machine 5, lever mechanism is pushed to increase,
It is rotated up back plate 6 around back support 903, rises back plate 6,6 end of back plate rotates down, while driving stern
Leg plate 7 is moved downward close to the side of back plate 6, due to calf plate 8 be it is fixed, buttocks and legs plate 7 can tilt down
It has a certain degree with calf plate 8, at this moment entire bed surface back plate 6 rises, the inclination decline of buttocks and legs plate 7, and calf plate 8 is motionless.Instead
It, makes back plate 6, buttocks and legs plate 7 and calf plate 8 be restored to parallel position by the retraction of linear electric machine 5.
The utility model can reach the function of dual-motor electric bed using a motor, both meet the needs of client,
Number of motors is reduced, production cost is reduced.Single motor electric driving bed structure is simple, and overall weight is light, and bed body passes through the combination side DIY
Formula assembling, reduces Package size, facilitates transport and installation, greatly reduce production cost, to improve market competition
Power.
