[0025] In actual use, when the seat frame is in the sitting state, the backrest assembly 3 of the seat frame is placed against the wall without gap, at this time the footrest assembly 7 is in the retracted state, the seat side plate assembly 2 is in the flat state, the backrest assembly 3 is in the retracted or upright state, and the slider 63 is located on one side of the cylinder barrel 64 close to the backrest assembly 3; when it is needed to adjust the seat frame to the reclining state, the driver is started, the slider 63 slides along the side of the cylinder barrel 64 away from the backrest assembly 3, the slider 63 drives the driving rod one 61 to rotate relative to the seat side plate assembly 2 through the driving rod two 62, the driving rod one 61 drives the linkage assembly one 4 and the footrest assembly 7 to rotate through the driving rod one 61, the linkage assembly one 4 cooperates with the seat side plate assembly 2 to unfold the footrest assembly 7, and the conversion from the sitting state to the reclining state of the seat frame is realized. When the seat frame is in the reclining state, the footrest assembly 7 is fully unfolded, the footrest assembly 7 cannot rotate relative to the seat side plate assembly 2 any more, the footrest assembly 7 limits the driving rod one 61 to rotate relative to the seat side plate assembly 2 through the linkage assembly one 4, at this time the linkage assembly one 4, the footrest assembly 7 and the seat side plate assembly 2 are in the locked state, when it is needed to continue to adjust the seat frame from the reclining state to the zero-gravity state, the driver continues to drive the slider 63 to slide away from the backrest assembly 3, the driving rod one 61 does not rotate relative to the seat side plate assembly 2 any more, the slider 63 can push the seat side plate assembly 2, the footrest assembly 7 and the backrest assembly 3 to move away from the wall through the driving rod two 62 and the driving rod one 61, at the same time, the linkage assembly two 5 can rotate relative to the base 1 and the seat side plate assembly 2 respectively, the linkage assembly two 5 and the seat side plate assembly 2 cooperate to drive the backrest assembly 3 to move away from the wall and unfold; in addition, the slider 63 drives the driving rod one 61 and the driving rod two 62 to move towards the footrest assembly 7 at the same time, the angle between the driving rod two 62 and the base 1 increases continuously, the driving rod two 62 continuously pushes the driving rod one 61, the seat side plate assembly 2 and the footrest assembly 7 upwards in the vertical direction, so that the end of the footrest assembly 7 close to the footrest assembly 7 inclines upwards, the end of the seat side plate assembly 2 close to the backrest assembly 3 and the backrest assembly 3 incline downwards, which is convenient for reclining, so as to realize the conversion from the reclining state to the zero-gravity state of the seat frame.

[0026] As Figure 2As shown, the linkage component 4 further includes a first link 41 and a second link 42. One end of the first drive rod 61 passes through one end of the first link 41 and the seat side panel assembly 2 in sequence. The first drive rod 61 is fixedly connected to the first link 41. The other end of the first link 41 is hinged to one end of the second link 42. The other end of the second link 42 is hinged to the foot pedal assembly 7.

[0027] When the seat frame transitions from a sitting position to a reclining position, the slider 63 drives the connecting rod 41, connecting rod 42, and foot pedal assembly 7 to rotate relative to the seat side panel assembly 2 via the second drive rod 62 and the first drive rod 61, thereby unfolding the foot pedal assembly 7. The linkage component 4 has a simple structure, the foot pedal assembly 7 is easy to unfold and retract, and the connection between the foot pedal assembly 7, the linkage component 4, and the seat side panel assembly 2 is convenient.

[0028] like Figures 3 to 4 As shown, the linkage component 2 5 further includes a third link 43, a fourth link 44, a fifth link 45, a sixth link 46, and a seventh link 47. One end of the third link 43 is hinged to the seat side panel assembly 2, the other end of the third link 43 is hinged to one end of the fourth link 44, the other end of the fourth link 44 is hinged to one end of the base 1, the middle part of the third link 43 is hinged to one end of the fifth link 45, the other end of the fifth link 45 is hinged to the middle part of the sixth link 46, one end of the sixth link 46 is hinged to both the backrest assembly 3 and the seat side panel assembly 2, the other end of the sixth link 46 is hinged to one end of the seventh link 47, and the other end of the seventh link 47 is hinged to the other end of the base 1.

[0029] When the seat frame transitions from a reclining position to a zero-gravity position, the seat side panel assembly 2, via link three 43, drives link four 44 to rotate relative to the base 1 towards the footrest assembly 7. Simultaneously, link three 43, via links five 45 and six 46, drives link seven 47 to rotate relative to the base 1 towards the footrest assembly 7. Link six 46, in conjunction with the seat side panel assembly 2, moves the backrest assembly 3 away from the wall and unfolds. Linkage component two 5 has a simple structure and is easy to connect with the seat side panel assembly 2 and the base 1. It not only guides the movement of the seat side panel assembly 2 and the backrest assembly 3 relative to the base 1 away from the wall, but also works with the seat side panel assembly 2 to unfold the backrest assembly 3. The easy unfolding and movement of the backrest assembly 3 facilitates placing the seat frame against the wall with zero distance in a seated position.

[0030] Further, the linkage assembly two 5 further comprises a linkage eight 48, a linkage nine 49 and a linkage ten 50, one end of the linkage eight 48 is hingedly connected to the middle part of the linkage four 44, the other end of the linkage eight 48 is hingedly connected to one end of the linkage nine 49, the middle part of the linkage nine 49 is hingedly connected to the seat side plate assembly 2, the other end of the linkage nine 49 is hingedly connected to one end of the linkage ten 50, the other end of the linkage ten 50 is hingedly connected to the footrest assembly 7.

[0031] When the seat frame is converted from the sitting state to the reclining state, the linkage assembly one 4 cooperates with the seat side plate assembly 2 to deploy the footrest assembly 7, and the footrest assembly 7 can drive the linkage ten 50 and the linkage nine 49 to rotate relative to the seat side plate assembly 2 at the same time, when the footrest assembly 7 is completely deployed, the seat frame is converted to the reclining state, and the footrest assembly 7 cannot rotate relative to the seat side plate assembly 2 any more, the footrest assembly 7 restricts the linkage nine 49 from rotating relative to the seat side plate assembly 2 through the linkage ten 50, that is, the linkage ten 50, the linkage nine 49, the footrest assembly 7 and the seat side plate assembly 2 are in a locked state, and at this time, the footrest assembly 7, the linkage assembly one 4 and the seat side plate assembly 2 are also in a locked state, when the seat frame is continuously converted from the reclining state to the zero-gravity state, the seat frame assembly can drive the linkage eight 48 and the linkage four 44 to rotate relative to the base 1 away from the backrest assembly 3 through the linkage nine 49, so that the posture conversion of the seat frame is more smooth.

[0032] As shown in Figure 4 Further, an arc-shaped guide groove 51 is arranged on the upper end surface of the linkage ten 50, and a limiting column 52 is arranged on the linkage three 43, and the limiting column 52 can be slidably connected with the arc-shaped guide groove 51.

[0033] When the seat frame is converted from the reclining state to the zero-gravity state, the linkage ten 50, the linkage nine 49 and the footrest assembly 7 are in a locked state, the linkage three 43 rotates relative to the linkage four 44 and the seat side plate assembly 2, and in the process of rotating, the limiting column 52 slides into the arc-shaped guide groove 51 and can slide upward relative to the arc-shaped guide groove 51, because the linkage ten 50 is in a locked state, the arc-shaped guide groove 51 can limit and guide the rotation of the limiting column 52 and the linkage three 43, thereby improving the accuracy and stability of the linkage three 43 in the process of rotating; when the seat frame is converted from the zero-gravity state to the reclining state, in the process of rotating, the limiting column 52 can slide downward in the arc-shaped guide groove 51 and then slide out of the arc-shaped guide groove 51, and the seat frame has high smoothness in the process of posture conversion.

[0034] Furthermore, the seat side panel assembly 2 includes a seat side panel 1 21 and a seat side panel 22. The middle part of the seat side panel 22 is fixedly connected to one end of the seat side panel 1 21. The backrest assembly 3 is hinged to one end of the seat side panel 22 and one end of the seat side panel 1 21 respectively. The other end of the seat side panel 22 is hinged to the connecting rod 6 46. The middle part of the seat side panel 1 21 is hinged to the connecting rod 9 49 and the connecting rod 3 43 respectively. The other end of the seat side panel 1 21 is hinged to the foot pedal assembly 7. The drive rod 1 61 passes through the middle part of the seat side panel 1 21 and is rotatably connected to the seat side panel 1 21.

[0035] Specifically, the seat side panel assembly 2 further includes a mounting assembly 23 connected to the seat side panel 21. The mounting assembly 23 can be connected to the external seat cushion, making the connection between the seat side panel assembly 2 and the external seat cushion convenient. In actual use, the seat side panel 21 is connected to the foot pedal assembly 7, the drive rod 61, and the linkage assembly 5 respectively. The linkage assembly 5, the drive rod 61, and the foot pedal assembly 7 will not interfere or resist each other during movement. The backrest assembly 3 is connected to the connecting rod 46, the seat side panel 22, and the seat side panel 21 respectively, which facilitates the seat side panel assembly 2 to drive the backrest assembly 3 to move away from the wall. The structure of the seat side panel assembly 2 is simple and compact.

[0036] Furthermore, the backrest assembly 3 includes a first rotating rod 31, a second rotating rod 32, a third rotating rod 33, and a fourth rotating rod 34. One end of the first rotating rod 31 is hinged to the first seat side panel 21, the other end of the first rotating rod 31 is hinged to one end of the second rotating rod 32, the middle part of the second rotating rod 32 is hinged to one end of the third rotating rod 33, the other end of the third rotating rod 33 is hinged to the sixth connecting rod 46, the middle part of the third rotating rod 33 is hinged to one end of the fourth rotating rod 34, and the other end of the fourth rotating rod 34 is hinged to the second seat side panel 22.

[0037] When the seat frame transitions from a reclining position to a zero-gravity state, the seat side panel 21 moves the backrest assembly 3 away from the wall. This movement, via link 6 46, drives the rotating rod 34, link 3 43, link 2 42, and link 1 41 to rotate, thus unfolding the backrest assembly 3. The backrest assembly 3 has a simple and compact structure. Connecting the rotating rod 34 to link 6 46 facilitates the rotation of the backrest assembly 3 relative to the seat side panel 21 by the linkage component 2 5, making unfolding and retraction of the backrest assembly 3 convenient. Connecting the rotating rod 34 and rotating rod 31 to the seat side panel assembly 2 allows the seat side panel assembly 2 to synchronously move the backrest assembly 3 away from the wall, facilitating placement of the backrest assembly 3 against the wall in a seated position and improving space utilization.

[0038] Furthermore, the seat frame also includes a reset member (not shown in the figure) connected to link 8 48 and link 6 46.

[0039] Specifically, the reset component can be an elastic element, such as a spring or tension spring. The end of link eight 48 near link nine 49 is connected to one end of the reset component, and the end of link six 46 near link seven 47 is connected to the other end of the reset component. When the seat frame transitions from a reclining state to a zero-gravity state, the distance between link six 46 and link eight 48 continuously increases, and the reset component is stretched and stores elastic potential energy. When the seat frame transitions from a zero-gravity state to a reclining state, the reset component releases its elastic potential energy and causes link six 46 and link eight 48 to move closer together. Link eight 48 pulls link four 44 to rotate relative to the base 1 towards the backrest assembly 3, which facilitates rapid posture transition of the seat frame and improves the posture transition efficiency.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
