With reference to the above description and the accompanying drawings, the following describes in detail the working principle of the couch 100 for assisting in getting up according to the present utility model, as follows:

referring to fig. 1, 5 and 6, when the sitting posture of the sofa main body 2 needs to be adjusted, the electric push rod is started, so that the output end of the electric push rod extends forward from the middle position of the stroke, and at this time, the output end of the electric push rod drives the lower end of the driving piece 6 to swing forward. The driving member 6 drives the first connecting rod 41, the first connecting rod 41 pushes the second connecting rod 42, the second connecting rod 42 pushes the third connecting rod 43, and the third connecting rod 43 pushes the footrest 22 and the fourth connecting rod 44 to act. At this time, the footrest 22 is moved forward and extended in the horizontal direction, and finally, the footrest 22 is extended in a substantially horizontal state with respect to the seat plate 21, so that the user lies flat. Meanwhile, the output end of the electric push rod drives the linkage rod 46 to move forward, and the back plate 23 is pulled to swing by the rear end of the linkage rod 46, so that the angle of the back plate 23 relative to the seat plate 21 becomes larger, and when the output end of the electric push rod extends to the forefront end of the stroke, the foot rest plate 22 and the back plate 23 are completely unfolded, so that the user is in a substantially lying state. When the sofa main body 2 needs to be restored to a state of normal sitting posture, the output end of the electric push rod is only required to be driven to shrink from the front end of the stroke to the middle position, and the foot rest plate 22 and the back rest plate 23 can be driven to reset, and at the moment, the adjacent two side edges of the first connecting rod and the third connecting rod are mutually propped against each other to form limit.

Referring to fig. 1 and 7, when a user needs to lift, the lift angle of the sofa main body 2 can be adjusted, specifically, the electric push rod is started, so that the output end of the electric push rod continues to shrink from the middle position to the rear end of the stroke. At this time, the output end of the electric push rod drives the driving member 6 to swing backward, the driving member 6 abuts against the abutting portion 211, and the pushing force of the driving member 6 is greater than the acting force of the sofa main body 2 caused by gravity, so that the seat board 21 moves backward. The second sliding seat 32 slides relatively to a second pin 39 at the upper end of the second supporting rod 34, and the second pin 39 slides from the rear end to the front end of the second sliding rail 321. At this time, the upper ends of the first support rod 33 and the second support rod 34 swing upward, so that they swing in the direction of approaching each other, thereby lifting the seat plate 21, and the first shaft pin 38 at the lower end of the second support rod 34 slides from the front end to the rear end of the first slide rail 311. Since the distance from the third pivot shaft 37 to the second pivot shaft 39 is greater than the distance from the third pivot shaft 37 to the second pivot shaft 36, the swing amplitude of the upper end of the second support bar 34 is greater than the swing amplitude of the upper end of the first support bar 33, so that the height of the rear end of the seat plate 21 is much higher than the height of the front end, and thus, the seat plate 21 assumes a forward inclined state of a large angle after rising to the highest, so that the user stands up very easily. When the sofa main body 2 needs to be restored to the normal sitting posture, the output end of the electric push rod only needs to be driven to extend from the rear end of the stroke to the middle position, at this time, the sofa main body 2 is subjected to a force caused by gravity which is greater than the pushing force of the driving piece 6 to push against the propping part 211, so that the seat board 21 moves towards the direction approaching to the frame 1, and finally, the sofa main body can be restored.

Compared with the prior art, the utility model has the advantages that the first adjusting mechanism 3 is arranged between the frame 1 and the sofa main body 2, one end of the second adjusting mechanism 4 is connected with the leaning board of the sofa main body 2, the output end of the telescoping device 5 is connected with the first adjusting mechanism 3 and the second adjusting mechanism 4 by arranging the telescoping device 5, the first adjusting mechanism 3 is driven when the output end of the telescoping device 5 moves from the middle position of the stroke to one end of the stroke, and the second adjusting mechanism 4 is driven when the output end of the telescoping device moves from the middle position of the stroke to the other end of the stroke, so that the forward tilting angle of the seat board 21 and the angle of the leaning board relative to the seat board 21 can be respectively adjusted. Therefore, the sofa 100 of the utility model only needs to use one telescopic device 5 when the functions of assisting the sofa to get up and adjusting the sitting posture of the sofa are realized, the structure is simplified, the compactness of the sofa structure is improved, and the production cost can be saved; meanwhile, only the telescopic action of one telescopic device 5 needs to be controlled during control, and the control is very simple and convenient.

The foregoing disclosure is merely illustrative of the principles of the present utility model, and thus, it is intended that the scope of the utility model be limited thereto and not by this disclosure, but by the claims appended hereto.
