Detailed ways

The embodiments of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve technical effects in the present application.

Please refer to FIG. 1 and FIG. 2 , the utility model provides a multi-directional adjustable chair bed, including:

The bed frame 1 and the bed board group 2 are slidably matched with the bed frame 1 through the frame 26 of the bed board group 2, so that the bed board group 2 can be displaced between the head and tail of the bed frame 1;

The fixed end of the first electric telescopic rod 3 is installed on the bed frame 1, and the extension end is arranged to extend and retract along the length direction of the bed frame 1. The extension stroke of the extension end includes a first stroke and a second stroke. When the end completes a complete extension stroke, the first stroke is carried out first and then the second stroke is carried out;

The hip connecting piece 4 is rotatably arranged on the hip bed board 21 of the bed board group 2, and is hinged with the extension end of the first electric telescopic rod 3, and the hip bed board 21 is arranged to be rotatable relative to the frame 26, so that it has the head side tilted up. or a tiled state, where:

In the first stroke of the extension 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 extension end exerts a thrust on the hip bed board 21 through the hip connector 4, and the hip bed board 21 pushes The thrust is transmitted to the frame 26, so that the entire bed board group 2 moves from the head of the bed to the end of the bed on the bed frame 1; in the second stroke of the extension end, the extension end of the first electric telescopic rod 3 passes the hip connector 4 so that the hip The head end of the bed board 21 is upturned. Specifically, the frame 26 is set so that when the extending end of the first electric telescopic rod 3 completes the first stroke, the frame 26 moves to the end of the bed on the bed frame 1 to the farthest Then, during the second stroke of the extension end of the first electric telescopic rod 3, the bed frame 1 cannot move, so that the extension end pushes the hip connector 4 to switch the hip bed board 21 from the flat state to the upper During the process, the back and the upper part of the body of the person lying on the bed can be lifted up, thereby realizing the function of assisting the lift. The person on the bed moves toward the end of the bed with the bed board group 2 on the bed frame 1, which is more convenient for getting up and leaving the bed.

Wherein, the fixed end of the first electric telescopic rod 3 is rotatably connected to the head side of the bed frame 1 , so that when the extending end of the first electric telescopic rod 3 performs the second stroke, the whole of the first electric telescopic rod 3 It will be upturned to ensure the realization of the lift-up function, and at the same time, the inclined state of the hip bed board 21 is used to achieve triangular support, which is more stable.

Further, it also includes a connecting body 5, and the two ends of the connecting body 5 are respectively connected with the bed frame 1 and the tail side of the calf bed board 22 in the bed board group 2. During the stroke, the end of the bed of the connecting body 5 is located outside the bed frame 1, and the calf bed plate 22 is designed to correspond to the position of the lower leg of the human body. And the calf bed board 22 can be rotated and connected. In this way, because one end of the connecting body 5 is connected to the bed frame 1 in rotation, when the first electric telescopic rod 3 is extended and retracted, the one end of the connecting body 5 that is connected to the bed frame 1 cannot be Translation, at this time, the end of the connecting body 5 connected with the calf bed board 22 is rotated relative to the end connected with the bed frame 1, and the height of the calf bed board 22 can be changed by its rotation, which can be set at the first electric telescopic rod 3 When the extension end of the first electric telescopic rod 3 is in the two states of fully retracted and fully extended, the height and state of the calf bed board 22 are set after the extension end of the first electric telescopic rod 3 completes the second stroke, the connecting body 5 The end connected with the calf bed board 22 is located outside the bed frame 1 in both the length direction and the width direction, so that at this time, the calf bed board 22 can swing downward, so as to place the calf of the human body in a curved state on the ground, and further improve the lifting function Specifically, when the extended end of the first electric telescopic rod 3 performs the second stroke, the connecting body 5 swings downward, and the calf bed board 22 moves downward from the top of the bed frame 1 through the end of the bed. Using this process, the user can The extension stroke of the first electric telescopic rod 3 is directly controlled as required, so as to realize the upturning process of the hip bed 21 and the lowering of the calf bed 22, and perfectly enjoy the lift-up function.

Wherein, when the extending 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, and in this way, on the one hand, when the lifting function is realized, the human calf is bent or placed on the At the same time, the calf bed board 22 is in a stowed state, so that the lift-up function is better.

Wherein, when the extending end of the first electric telescopic rod 3 reverses the first stroke, the connecting body 5 swings upward, so that the calf bed 22 is tilted upward toward the end of the bed. In this way, the user can still use the first electric telescopic rod. 3. The retraction stroke of the telescopic end is used for the laying process of the body buttocks and above, and at the same time, the calf part can be lifted by the upturning of the calf bed plate 22 to realize the leg-lifting function.

Further, a thigh bed 23 is rotatably connected between the buttocks bed 21 and the calf bed 22, and a back bed 24 is rotatably connected to the head side of the buttocks bed 21, wherein: the back bed 24 and the buttocks 21 are provided with a second electric The telescopic rod 6 is used to adjust the inclination angle of the back deck 24; a third electric telescopic rod 7 is provided between the thigh deck 23 and the buttocks deck 21 to adjust the inclination angle of the thigh deck 23, using the thigh deck 23 and the back deck 24 Cooperating with the hip bed 21 and the calf bed 22, when the hip bed 21 and the calf bed 22 are in different states, the state of the back bed 24 and the thigh bed 23 can be directly adjusted to realize various shapes, so as to match the various postures of the user and improve the comfort.

The main rail 11 is provided on the bed frame 1 , and the frame 26 is slidably matched with the bed frame 1 through the main rail wheel 25 . Support and guide.

The hip connector 4 includes a shaft body 41, a shaft 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, and the shaft sleeve 42 is rotatably sleeved on the shaft body 41. On the other hand, by fixing one end of the connecting frame 43 with the shaft sleeve 42 and sliding the other end with the hip bed board 21, the head side of the connecting frame 43 is inclined upward, and the extension end of the first electric telescopic rod 3 is hinged in the connecting On the frame 43, an auxiliary rail 21a is arranged on the hip bed board 21, and the head end of the connecting frame 43 is slidably arranged in the auxiliary rail 21a through the auxiliary rail wheel 43a. The connecting frame 43 is displaced relative to the buttocks bedboard 21 when it pushes the buttocks bedboard 21 to rotate, so as to achieve a lift-up function.
