[0026] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Please refer to Figure 1 and Figure 2 As shown, the present invention provides a multi-directional adjustable chair bed, comprising:

[0028] The bed frame 1 and the bed board assembly 2 are slidably matched with the bed frame 1 through the frame 26 of the bed board assembly 2, so that the bed board assembly 2 can be displaced between the head and foot of the bed frame 1;

[0029] A first electric telescopic rod 3, a fixed end of which is mounted on the bed frame 1, and an extended end is configured to be extended along the length direction of the bed frame 1, and the extension stroke of the extended end includes a first stroke and a second stroke. When the extended end completes a complete extension stroke, the first stroke is performed first and then the second stroke;

[0030] The buttocks connecting member 4 is rotatably arranged on the buttocks bed board 21 of the bed board group 2 and is hinged to the extended end of the first electric telescopic rod 3. The buttocks bed board 21 is arranged to be rotatable relative to the frame 26 so that it has a state where the head side of the bed is tilted or laid flat, wherein:

[0031] In the first stroke of the extended end, the first electric telescopic rod 3 drives the bed board group 2 to move toward the end of the bed through the hip connector 4. At this time, the extended end applies a thrust to the hip bed board 21 through the hip connector 4, and the hip bed board 21 transmits the thrust to the frame 26, thereby causing the entire bed board group 2 to move from the head of the bed to the end of the bed on the bed frame 1; in the second stroke of the extended end, the extended end of the first electric telescopic rod 3 causes the head end of the hip bed board 21 to tilt upward through the hip connector 4. Specifically, the frame 26 is configured so that when the extended end of the first electric telescopic rod 3 completes the first stroke, the frame 2 6 moves to the farthest point on the bed frame 1 toward the end of the bed, and then, during the second stroke of the extended end of the first electric telescopic rod 3, the bed frame 1 cannot move, so that the extended end pushes the hip connector 4 to switch the hip bed board 21 from a flat state to an upturned state. In this process, the back and above parts of the body of the person lying on the bed can be lifted, thereby realizing the assisting function. At the same time, combined with the bed board group 2 in the first stroke of the first electric telescopic rod 3, the person on the bed follows the bed board group 2 on the bed frame 1 to move toward the end of the bed, which makes it more convenient to get up and leave the bed.

[0032] Among them, the fixed end of the first electric telescopic rod 3 is rotatably connected to the head side of the bed frame 1. Such an arrangement enables the first electric telescopic rod 3 to be tilted upward as a whole when the extended end of the first electric telescopic rod 3 performs the second stroke to ensure the realization of the assisting function. At the same time, its inclined state is used to cooperate with the inclined state of the buttocks bed board 21 to achieve triangular support, which is more stable.

[0033] Furthermore, it also includes a connecting body 5, the two ends of which are rotatably connected to the bed frame 1 and the tail side of the calf bed board 22 in the bed board group 2, wherein when the extended end of the first electric telescopic rod 3 completes the first stroke, the tail end of the connecting body 5 is located outside the bed frame 1, and the calf bed board 22 is designed corresponding to the calf position of the human body. The connecting body 5 can be plate-shaped, tubular or other shapes, and it only needs to have its two ends rotatably connected to the bed frame 1 and the calf bed board 22, respectively. In this arrangement, since one end of the connecting body 5 is rotatably connected to the bed frame 1, when the first electric telescopic rod 3 is extended or retracted, the end of the connecting body 5 connected to the bed frame 1 cannot be translated. At this time, the end of the connecting body 5 connected to the calf bed board 22 is rotated relative to the end connected to the bed frame 1, and the height of the calf bed board 22 is changed by its rotation, which can be set at the first electric telescopic rod 3. When the extended end of the electric telescopic rod 3 is in the two states of fully retracted and fully extended respectively, the height and state of the calf bed board 22 are set, and after the extended end of the first electric telescopic rod 3 completes the second stroke, the end of the connector 5 connected to the calf bed board 22 is located outside the bed frame 1 in the length direction and the width direction, so that at this time, the calf bed board 22 can swing downward to place the human body's calf on the ground in a bent state, further improving the assisting function. Specifically, when the extended end of the first electric telescopic rod 3 performs the second stroke, the connector 5 swings downward and makes the calf bed board 22 move downward from the top of the bed frame 1 through the end of the bed. Using this process, the user can directly control the extension stroke of the first electric telescopic rod 3 according to needs, realize the process of the buttocks bed board 21 tilting up and the calf bed board 22 descending, and perfectly enjoy the assisting function.

[0034] Among them, when the extended end of the first electric telescopic rod 3 completes the second stroke, the calf bed board 22 is vertically stored at the end of the bed frame 1. With this arrangement, when the assisting function is realized, the human calf is bent or placed on the ground. At the same time, the calf bed board 22 is in a stored state, which makes the assisting function better.

[0035] Among them, when the extended end of the first electric telescopic rod 3 performs the first stroke in the reverse direction, the connecting body 5 swings upward, so that the calf bed board 22 is tilted toward the end of the bed. In this way, the user still uses the first electric telescopic rod 3 and uses the contraction stroke of its telescopic end for the body's buttocks and above to lie flat. At the same time, the calf part can be lifted by the upward tilt of the calf bed board 22 to achieve the leg lifting function.

[0036] Furthermore, a thigh board 23 is rotatably connected between the buttocks bed board 21 and the calf bed board 22, and a back bed board 24 is rotatably connected to the head side of the buttocks bed board 21, wherein: a second electric telescopic rod 6 is provided between the back bed board 24 and the buttocks bed board 21, for adjusting the inclination angle of the back bed board 24; a third electric telescopic rod 7 is provided between the thigh bed board 23 and the buttocks bed board 21, for adjusting the inclination angle of the thigh bed board 23. By utilizing the thigh bed board 23 and the back bed board 24 to cooperate with the buttocks bed board 21 and the calf bed board 22, the states of the back bed board 24 and the thigh bed board 23 can be directly adjusted when the buttocks bed board 21 and the calf bed board 22 are in different states, thereby realizing a variety of shapes to cooperate with various postures of the user and improve comfort.

[0037] The bed frame 1 is provided with a main rail 11 , and the frame 26 is slidably matched with the bed frame 1 through the main rail wheel 25 . The main rail 11 is provided on both inner sides of the bed frame 1 with a wheel for supporting and guiding the movement of the bed board assembly 2 .

[0038] The hip connector 4 includes a shaft body 41, a sleeve 42 and a connecting frame 43, wherein: the shaft body 41 is fixed on the frame 26 and is located below the hip bed board 21 in the height direction; the sleeve 42 is rotatably sleeved on the shaft body 41; by fixing one end of the connecting frame 43 to the sleeve 42 and slidingly cooperating with the hip bed frame 1, the head side of the connecting frame 43 is tilted upward, and the protruding end of the first electric telescopic rod 3 is hinged on the connecting frame 43; a secondary rail 21a is provided on the hip bed board 21; the head end of the connecting frame 43 is slidably set in the secondary rail 21a through a secondary rail wheel 43a; one secondary rail 21a is set on the inner wall on both sides of the hip bed board 21, and is used for the connecting frame 43 to move relative to the hip bed board 21 when the hip bed board 21 is pushed to rotate, so as to realize the assisting function.
