When the user needs to sit up (the back is upright), the first push-pull rod assembly 401 is extended, so that the first bed plate frame 101 is driven to rotate by taking the rotation centers of the rotary support frame 3 and the first bed plate frame 101 as circle centers, and the back and the head of the user are supported by the first bed plate frame 101, so that the user can sit up; in the sitting posture, when the legs of the user need to be bent, the second push-pull rod assembly 402 can be extended, so that the second bed plate frame 102 is driven to rotate by taking the rotation centers of the rotary support frame 3 and the second bed plate frame 102 as the circle center, at the moment, the third push-pull rod assembly 403 is retracted, so that the third bed plate frame 103 is driven to rotate by taking the rotation centers of the second bed plate frame 102 and the third bed plate frame 103 as the circle center, the second bed plate frame 102 and the third bed plate frame 103 are raised to form a triangular support, and the structure is shown in fig. 9 and is used for supporting the thighs and the calves of the user, so that the comfort of the user in the sitting posture can be improved.
When the user needs to get out of the bed, the fourth push-pull rod assembly 404 retracts, that is, the fourth push-pull rod assembly 404 moves from the position shown in fig. 10 to the position shown in fig. 11, so as to drive the rotating support frame 3 to rotate relative to the support frame 2, and enable the rotating support frame 3 to rotate 90 ° relative to the support frame 2, and enable the foot of the user to move from the tail of the automatic device to the middle of the side edge of the automatic device through rotation, at this time, the second bed frame 102 can be slowly driven to rotate through the second push-pull rod assembly 402, and enable the second side edge 102b of the second bed frame 102 to rotate to be parallel to the support frame 2, at this time, the structure of the automatic device is shown in fig. 12. In order to facilitate the old people to get out of the bed, the second side edge 102b of the second bed plate frame 102 can be rotated to the lower part of the supporting frame 2, and the getting-in action can be completed by referring to the getting-out action.
The embodiment of the invention provides an automatic device for assisting in getting on and off a bed, which can support thighs, shanks, backs and heads of a user, and can adjust angles of a first bed plate frame, a second bed plate frame and a third bed plate frame in each posture according to requirements, so that the conversion between the postures of lying, sitting and getting off the bed after the rotation of the bed plate frames is realized, further, the user is helped to complete the actions of getting on and off the bed, the getting on and off the bed is more convenient, and the life quality of the old can be remarkably improved.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
