Referring to fig. 8 and 9, two first guide assemblies are provided, one on each side of the driving cylinder 15 and one corresponding to each pedal member 19. The first guide assembly comprises a lift rail fixedly mounted on the side of the outer mounting frame 14 facing the inner mounting frame 13 and forming an inclined guide surface 28, and a rolling member 27. The upper end of the guide surface 28 is located at the end of the guide surface 28 facing the inner mounting bracket 13, and the roller 27 is pivotally connected to the inner rod 22. The rolling elements 27 may be rolling bearings. When the pedal member 19 moves until the rolling member 27 abuts against the guide surface 28, if the pedal member 19 continues to move toward the outer mounting frame 14, the rolling member 27 slides downward along the guide surface 28, and the pedal member 19 rotates upward relative to the linkage seat 25, completing the lifting.

Referring to fig. 8 and 10, in order to prevent the pedal member 19 from moving excessively when being lifted and folded, a limiting groove 29 is formed at one end of the inner rod 22 connected to the pedal mounting portion 23, and a limiting shaft 30 is mounted on the pedal mounting portion 23; when the pedal member 19 moves to the lifting limit, the limit shaft 30 abuts against one end of the limit groove 29.

Referring to fig. 11, the inner side and the outer side of the linkage base 25 are provided with a limiting member 31. The limiting member 31 is a limiting nail. One limiting piece 31 is arranged on the inner side of the linkage seat 25 and corresponds to the inner rod 22, and two limiting pieces 31 are arranged on the outer side of the linkage seat 25 and correspond to the outer rod 21 along the periphery of the outer rod 21. When the pedal member 19 is folded to move to the horizontal position, the stopper 31 abuts against the inner rod 22 and the outer rod 21.

Referring to fig. 8, in order to slow down the lifting and folding speed of the foothold 3, a limit guide assembly is provided below the lower seating unit 7. Two limiting guide assemblies are arranged and are respectively positioned at two sides of the driving cylinder 15, and one limiting guide assembly corresponds to one pedal piece 19. The limit guide assembly comprises a translation buffer assembly 32 and a lifting buffer assembly 33. The translational buffer assembly 32 includes a slide rail 34 disposed along the moving direction of the linkage 16 and a support tube 35 slidably disposed outside the slide rail 34. The support tube 35 is fixedly connected to the linkage seat 25. One end of the slide rail 34 is fixedly connected to the inner mounting frame 13, a through groove for the slide rail 34 to pass through is formed in the outer mounting frame 14, and a buffer gap is formed between the slide rail 34 and the through groove. Referring to fig. 12, the self-lubricating bush 41 is installed in the support pipe 35, and the support pipe 35 is slidably connected to the slide rail 34 through the self-lubricating bush 41. The self-lubricating bushes 41 are provided in a plurality, and adjacent self-lubricating bushes 41 are arranged continuously or at intervals. Illustrated in this embodiment are self-lubricating liners 41 which are spaced apart.

The self-lubricating bushes 41 restrict the freedom of the support pipe 35 with respect to the slide rail 34 in the up-down and left-right directions. The support tube 35 can perform linear reciprocating motion under the action of the driving force, so that the pedal assembly 17 moves more stably, and the probability of shaking of the pedal assembly 17 is reduced.

Referring to fig. 8 and 9, the lift bumper assembly 33 includes a limit guide 36 fixedly mounted to the outer mount 14, a limit guide 37 mounted to the outer pole 21, and a limit plate 38 fixedly mounted to the outer mount. Referring to fig. 13 and 14, the limit guide 36 is provided with a guide groove 39. The position limiting guide 37 is slidably coupled in the guide groove 39 when the rolling member 27 slides along the guide surface 28. The trajectory of the guide groove 39 is larger than the trajectory of the movement of the footboard element 19 from the horizontal to the limit of lifting. The limit plate 38 is positioned above the limit guide plate 36; when the stopper guide 37 slides inside the guide groove 39 with respect to the guide groove 39, the stopper plate 38 is slidably abutted against one side wall of the outer rod 21.

The friction between the supporting tube 35 and the sliding rail 34 and the friction between the limiting guide block 37 and the guide groove 39 slow down the folding and lifting speed of the pedal part 19, and bring comfort experience to people. When the pedal assembly 17 is manually lifted upwards by external force, the limiting guide block 37 is in contact with the upper end surface of the guide groove 39, the outer rod 21 abuts against the limiting plate 38 to form a limiting effect, and the pedal assembly 17 cannot move upwards or downwards. Thereby making the pedaling apparatus more stable. And because the track of the guide groove 39 is larger than the movement track of the pedal piece 19 from the horizontal position to the lifting limit, the limit guide block 37 and the limit guide plate 36 cannot collide instantaneously during lifting, thereby achieving the effect of silence.

Referring to fig. 15, in order to improve structural strength, the second guide assembly is provided with a reinforcing member 40, and the two limit guides 36 and the two lift rails are fixedly connected to one reinforcing member 40. The reinforcing rods may reduce the probability of bending deformation of the limit guides 36 and the lift rails.

The implementation principle of the sofa with the lying leg translation and lifting functions in the embodiment of the application is as follows:

the sofa has three states of a first state, a second state and a third state, and is respectively suitable for different occasions. In the first state, the headrest portion 2 moves to the middle of the sitting portion 1 relative to the sitting portion 1, and the footrest portion 3 is folded and hidden under the sitting portion 1, so that the sofa can be used as a common sofa. In the second state, when the headrest portion 2 moves to the middle of the sitting portion 1 relative to the sitting portion 1 and the footrest portion 3 is lifted to one end of the sitting portion 1, a person can lie on the functional sofa in half. In the third state, when the headrest 2 moves to the position farthest from the footrest 3 with respect to the seat 1 and the footrest 3 is lifted to one end of the seat 1, a person can lie on the functional sofa.

The conversion between the three forms of the sofa is completed by the headrest part 2 moving relative to the sitting part 1 and the pedal part 3 lifting and folding relative to the sitting part 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
