DETAILED DESCRIPTION OF THE EMBODIMENTS

The implementation modes of the present disclosure will be described in detail in conjunction with the accompanying drawings and embodiments, so as to fully understand and implement a realizing process of how the present disclosure applies technical means to solve technical problems and achieve technical effects.

Referring to FIG. 1 and FIG. 2, the present disclosure provides a multi-directional adjustable chair bed, including:

a bedstead 1 and a bed plate group 2, the bed plate group 2 being capable of moving between a bed head and a bed tail of the bedstead 1 by means of sliding fit between a framework 26 of the bed plate board 2 and the bedstead 1;

a first electric telescopic rod 3, a fixed end of which is mounted on the bedstead 1 and an extending end of which is telescopic in a lengthwise direction of the bedstead 1, an extending stroke of the extending end including a first stroke and a second stroke, and when the extending end finishes one complete extending stroke, the second stroke being executed after the first stroke; and

a hip connection member 4 rotatably arranged on a hip bed plate 21 of the bed plate group 2 and hinged to the extending end of the first electric telescopic rod 3, the hip bed plate 21 being rotatable relative to the framework 26 so that it has an upwarp or horizontal state of a bed head side. In particular:

in the first stroke of the extending end, the first electric telescopic rod 3 drives, through the hip connection member 4, the bed plate group 2 to move towards the bed tail. At this time, the extending end applies a thrust to the hip bed plate 21 through the hip connection member 4, and the hip bed plate 21 transmits the thrust to the framework 26, so that the whole bed plate group 2 moves on the bedstead 1 from the bed head to the bed tail. In the second stroke of the extending end, the extending end of the first electric telescopic rod 3 enables, through the hip connection member 4, the bed head end of the hip bed plate 21 to upwarp. Specifically, the framework 26 is disposed to move on the bedstead 1 towards one side of the bed tail to the farthest point when the extending end of the first electric telescopic rod 3 finishes the first stroke; therefore, in the process that the extending end of the first electric telescopic rod 3 executes the second stroke, the bedstead 1 cannot move, so that the extending end pushes the hip connection member 4 to enable the hip bed plate 21 to be switched from a horizontal state to an upwarp state; in this process, the back of the boy and parts above the back of people lying on the bed can be lifted, thus realizing a stand-up assisting function; meanwhile, in combination with the bed plate group 2, in the first stroke of the first electric telescopic rod 3, people in the bed moves with the bed plate group 2 on the bedstead 1 towards the bed tail, so that it is more convenient for people to get up and leave a bed body.

In particular, the fixed end of the first electric telescopic rod 3 is rotatably connected to the bed head side of the bedstead 1. In this way, when the extending end of the first electric telescopic rod 3 executes the second stroke, the overall first electric telescopic rod 3 will upwarp, so as to ensure that the stand-up assisting function is realized; and at the same time, the inclined state of the first electric telescopic rod isused to cooperate with the inclined state of the hip bed plate 21 to realize triangular supporting, which is stabler.

Further, a connection body 5 is further included; two ends of the connection body 5 are respectively rotatably connected to the bedstead 1 and a bed tail side of a crus bed plate 22 in the bed plate group 2. In particular, when the extending end of the first electric telescopic rod 3 finishes the first stroke, the bed tail end of the connection body 5 is located outside the bedstead 1; the crus bed plate 22 is designed in a manner of corresponding to the crus position of a user; the connection body 5 may be platy, tubular, or of other shapes, as long as its two ends are respectively rotatably connected to the bedstead 1 and the crus bed plate 22. In this way, since one end of the connection body 5 is rotatably connected to the bedstead 1, when the first electric telescopic rod 3 extends and retracts, the end of the connection body 5 connected to the crus bed plate 22 rotates relative to the end connected to the bedstead 1, and the rotation is used to change the height of the crus bed plate 22, so that when the extending end of the first electric telescopic rod 3 is in a completely retracted state and a completely extended state, the height and the state of the crus bed plate 22 can be set; furthermore, after the extending end of the first electric telescopic rod 3 finishes the second stroke, the end of the connection body 5 connected to the crus bed plate 22 is located outside the bedstead 1 in a lengthwise direction and a width direction, so that at this time, the crus bed plate 22 may swing downwards to place the crus of the user on the ground in a bent state, thereby further enhancing the stand-up assisting function. Specifically, when the extending end of the first electric telescopic rod 3 executes the second stroke, the connection body 5 swings downwards, and the crus bed plate 22 passes through the bed tail from a position above the bedstead 1 and moves downwards. By this process, the user can directly control the extending stroke of the first electric telescopic rod 3 according to a need, so as to realize upwarping of the hip bed plate 21 and descending of the crus bed plate 22 to perfectly enjoy the stand-up assisting function.

In particular, when the extending end of the first electric telescopic rod 3 finishes the second stroke, the crus bed plate 22 is vertically stored at the bed tail of the bedstead 1. In this way, on the one hand, when the stand-up assisting function is realized, the crus of the user bends or is placed on the ground; and at the same time, the thigh bed plate 22 is in a stored state to make the stand-up assisting function better.

In particular, when the extending end of the first electric telescopic rod 3 reversely extends the first stroke, the connection body 5 swings upwards, so that the thigh bed plate 22 upwarps towards the bed tail side. In this way, the user still uses the first electric telescopic rod 3, and the retracting stroke of the extending end is applied to lying of the hip and parts above the hip of the body; and at the same time, the crus part is lifted up with the upwarping of the crus bed plate 22 to realize a left raising function.

Further, a thigh bed plate 23 is rotatably connected between the hip bed plate 21 and the crus bed plate 22, and the bed head side of the hip bed plate 21 is rotatably connected with a back bed plate 24; in particular, a second electric telescopic rod 6 is arranged between the back bed plate 24 and the hip bed plate 21 and is used to adjust an inclination angle of the back bed plate 24; a third electric telescopic rod 7 is arranged between the thigh bed plate 23 and the hip bed plate 21 and is used to adjust an inclination angle of the thigh bed plate 23. The thigh bed plate 23 and the back bed plate 24 cooperate with the hip bed plate 21 and the crus bed plate 22, so that when the hip bed plate 21 and the crus bed plate 22 are in different states, the states of the back bed plate 24 and the thigh bed plate 23 are directly adjusted to realize various forms and cooperate with various postures of the user, thereby improving the comfort.

In particular, the bedstead 1 is provided with a main rail 11; the framework 26 is in sliding fit with the bedstead 1 through a main rail wheel 25; and each of two inner side surfaces of the bedstead 1 is provided with one main rail 11 to support and guide the movement of the bed plate group 2.

The hip connection member 4 includes a shaft body 41, a shaft sleeve 42, and a connection frame 43. In particular, the shaft body 41 is fixed on the framework 26 and is located below the hip bed plate 21 in a height direction; the shaft sleeve 42 is rotatably sleeved on the shaft body 41; one end of the connection frame 43 is fixed to the shaft sleeve 42 and the other end is in sliding fit with the hip bedstead 1, so that the bed head side of the connection frame 43 is inclined upwards; and the extending end of the first electric telescopic rod 3 is hinged to the connection frame 43. The hip bed plate 21 is provided with an auxiliary rial 21a, and the bed head end of the connection frame 43 is slidably arranged in the auxiliary rail 21a through an auxiliary rail wheel 43a. An inner wall of each of two sides of the hip bed plate 21 is provided with one auxiliary rail 21a used to move relative to the hip bed plate 21 when the connection frame 43 pushes the hip bed plate 21 to rotate, so as to realize the stand-up assisting function.
