Synchronously rotate in the direction of the frame 11 until it overlaps the frame 11 and the third included angle θ3 becomes 180 degrees. Therefore, it is suitable for laying the lower body of the human body flat on the second bed frame unit 3.

Referring to FIGS. 2 and 7, when the first motor group 44 drives the first telescopic group 43 to extend from the shortest length, as shown in FIG. 7, the first connecting member 42 is driven by turning over the ear seats 433 The second rails 412 rotate in a clockwise direction, and the second rollers 414 on the second rails 412 push the first rails 412 to rotate in a clockwise direction in synchronization with the head plate frame 22, And reduce the second included angle θ2 to about 160 degrees, refer to FIGS. 2 and 5, and then, when the first motor group 44 drives the first telescopic group 43 to extend to the longest length, it will pass through the ear seats 433 Continuously turning the first connecting member 42 and the second rail members 412 to rotate in a clockwise direction, so that the second rail members 412 slide on the first rail members 411 during the rotation process, and push the The second rail 412 and the back plate frame 21 rotate in a direction away from the frame 11 until the first bed frame unit 2 is located at the tilted position, and at the same time, the first rails 42 pushed up by the first The rail 411 is also limited by the second rails 42, and the first rollers 413 are used to stably support the head frame 22, so that the head frame 22 and the second frame between the head frame 22 and the back frame 21 The angle θ2 remains fixed. Thereby, it is suitable for supporting the head and back of the human body, so that the human body can sit and lean on the first bed frame unit 2 in an ergonomic posture.

What is important is that when the back plate frame 21 rotates away from the frame 11, the waist top unit 6 is synchronously driven to rotate in a clockwise direction, and each ejection member 62 is pulled to expand and the respective linkage member The fourth included angle θ4 of 61, when the first bed frame unit 2 is at the tilted position, each linkage 61 will form four connections with the respective ejector 62, the frame 11, and the back frame 21 The lever mechanism is stabilized at the dead center position of the locked state, thereby enabling the waist top member 63 to be positioned and away from the back plate frame 21, and is suitable for supporting the waist of the human body.

When the second motor group 55 drives the second telescopic group 54 to extend to the longest length, the second connecting piece 53 and the sliding pieces 51 are turned counterclockwise through the ear seats 543, so that the The sliding member 51 rotates in a direction away from the frame 11 and pushes the calf frame 32 to reduce the third included angle θ3 with the thigh frame 31. Therefore, it is suitable for supporting the thighs and calves of the human body in an arched state.

It should be noted that the starting position of the first bed frame unit 2 is not limited to 0 degrees, and in other variations of this embodiment, it may also be 5 degrees, 10 degrees or other angles.

Based on the above description, the advantages of the foregoing embodiments can be summarized as follows:

1 and 2, the present invention can drive the first bed frame unit 2 by the first drive unit 4 to change the angle with the bracket unit 1, and at the same time, the linkage parts 61, the ejection parts 62 and the The linkage relationship of the first bed frame unit 2 enables the waist top member 63 to be synchronized away from the first bed frame unit 2 when the first drive unit 4 is shared, so as to achieve the effect of supporting the waist of the human body, thereby improving use It is comfortable, and the present invention only has two motor groups, which not only can simplify the structure, but also save electric energy.
