Preferably, the outer edge profile of the first roller 29 is V-shaped, and the guide chute 14 is also V-shaped or substantially V-shaped (i.e. has a gradually narrowing outer edge) so as to be able to adapt to the shape of the first roller 29. The mounting plate 27 is provided with a first cylindrical pin 30, and the first roller 29 is rotatably mounted on the first cylindrical pin 30.

When the back motor 23 is pushed out forwards to act, the back motor 23 drives the back support frame 9 to swing, the guide sliding chute 14 on the back plate 2 is clamped on the four first idler wheels 29 of the back support frame 9, so that the back support frame 9 can only swing along with the direction parallel to the four first idler wheels 29, as the two ends of the waist plate 3 are respectively hinged to the back plate 2 and the hip plate 4, the waist plate 3 can only rotate and lift around the hinge 12 at one end, the back plate 2 lifts and drives the waist plate 3 to lift together, and the back plate 2 and the waist plate 3 are linked and act simultaneously; moreover, by using the first roller 29 and the guide chute 14 in a matching manner, the axial deviation of the roller which can occur in the rolling process is eliminated, and the strength and the service life of the product are improved by improving the structure.

In addition, a back support bar 16 and a first fixing base 17 may be provided, which may be directly provided on the fixed frame 8.

Referring to fig. 7 and 8, the lumbar support mechanism 11 includes a trough plate 31, a link pipe 32, and a link mechanism disposed therebetween. The slot plate 31 is fixed to the bottom of the ejector plate 13 so as to bring the ejector plate 13 into motion. The waist motor 24 is fixed at the bottom of the waist plate 3, the waist motor 24 is connected with the linkage pipe 32, when the waist motor 24 acts, the linkage pipe 32 acts and drives the liftout plate 13 to lift through the link mechanism, namely, the link mechanism acts on converting the force of the linkage pipe 32 and transmitting the force to the groove plate 31, and further drives the liftout plate 13 to act together, so as to realize the lifting of the liftout plate 13.

In this embodiment, the cross section of the slot plate 31 is C-shaped, the bottom of the slot plate is provided with a groove, the side of the slot plate 31 is provided with a waist-round slot 38 communicated with the groove, the link mechanism includes a first link rod 33 in L-shape, the bottom end a of the first link rod 33 is hinged with the linkage tube 32, the turning point B of the first link rod 33 is hinged with a fixing member 34 fixed on the waist plate 3, the top end D of the first link rod 33 is provided with a second roller 36 capable of rolling along the groove, the second roller 36 is rotatably mounted on a second cylindrical pin 37, the second cylindrical pin 37 is capable of sliding along the waist-round slot 38, the first link rod 33 is hinged with a second link rod 35 at a position between the turning point and the top end (i.e. at the position C in the figure), as shown in the figure, the number of the first link rods 33 is two, the first link rods 33 are arranged side by side, the second roller 36 is sandwiched therebetween, and the second link rod 35 is connected therebetween, the other end of the second connecting rod 35 is hinged to the slot plate 31. As shown in fig. 7, the two sets of link mechanisms are respectively disposed at two ends of the slot plate 31 and the linkage pipe 32, wherein the left end is in a disassembled state, and the right end is in an assembled state.

The action process of the waist supporting mechanism 11 is as follows: waist motor 24 promotes linkage pipe 32, drives the AB section of head rod 33 and swings forward round hole B, and simultaneously, the BD section of head rod 33 swings upward round hole B, and then promotes frid 31 upward movement, and waist circle groove 38 on second connecting rod 35 and the frid 31 has then guaranteed that frid 31 can not have the ascending displacement of left and right sides when upward movement.

The electric bed frame introduced in the invention has the displacement function, the movable bed frame 7 is connected with the fixed bed frame 8 in a sliding way, namely when the back plate 2 is lifted, the movable bed frame 7 can automatically move towards the direction of the bed head, so that the distance between the eyes of a user and a television can not be shortened when the user watches the television in a TV mode of using the electric bed.

In addition, because there is no support tube under the lower leg plate 6 of the electric bed, the lower leg plate 6 may collapse after the electric bed is used for a long time, which may affect the appearance. Therefore, the method adopts the following scheme to improve the method:

referring to fig. 9 to 12, in order to adjust the angle of the lower leg plate 6, the lower leg plate 6 is hinged to the upper leg plate 5, an adjusting piece 20 is disposed at the bottom of the lower leg plate 6, a moving area is disposed in the adjusting piece 20, a leg support bar 18 is hinged to the movable bed frame 7, the other end of the leg support bar 18 is hinged to a second fixing seat 19, and the second fixing seat 19 can move along the width direction of the lower leg plate 6 in the moving area and is fixed to the lower leg plate 6 through a fixing component.

In order to prevent the second fixing seat 19 and the adjusting plate 20 from deviating, the inner wall of the moving area is provided with a plurality of teeth, and the periphery of the second fixing seat 19 is also provided with teeth capable of meshing with the teeth of the moving area. The teeth can facilitate the second fixing seat 19 and the adjusting sheet 20 to determine the position, and avoid the generation of offset. Furthermore, the fixing part is a bolt, a waist round hole is formed in the fixing seat, and the bolt penetrates through the waist round hole and is fixedly connected with the shank plate 6. Under the circumstances that the bolt is not locked, second fixing base 19 can carry out the back-and-forth movement of certain degree to realize the regulation of shank plate 6 height from top to bottom, the inboard (the inner wall that moves the region promptly) of adjustment flap 20 and the outside of second fixing base 19 all have a row of fine tooth, can make second fixing base 19 and adjustment flap 20 keep relatively fixed through the meshing of tooth, two holes on the adjustment flap 20 are the round hole, as shown in figure 10, with bolt fastening back adjustment flap 20 on shank plate 6 can not take place the skew, just so can ensure that the adjustment flap is fixed completely relative shank plate 6, make the regulating effect can keep for a long time.

Referring to fig. 13 to 15, the multi-sectional backboard foldable electric bedstead of the present invention can support the waist of a person when being carried up, so as to be not suspended, fit the body curve more, and conform to the human engineering; furthermore, an ejector plate 13 is dug on the waist plate 3, an ejector device is added below the waist plate 3, and a user can freely adjust the position of the ejector plate 13 within a certain range according to the requirement of the user, so that different states shown in the figures are realized.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
