For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0021] like Figure 1-6 A seat frame with a rocking chair function comprises a bottom frame 1, a front rocking bar 2 is movably connected to the upper left and right sides of the front end of the bottom frame 1, a rear rocking bar 3 is movably connected to the upper left and right sides of the rear end of the bottom frame 1, a connecting rod 4 is movably connected to the bottom of the front rocking bar 2, one end of the connecting rod 4 away from the front rocking bar 2 is movably connected to the bottom of the rear rocking bar 3, a support rod 5 is arranged between the connecting rods 4 on the left and right sides, a frame body 6 is arranged above the support rod 5, side panels 7 are respectively arranged on the left and right sides of the frame body 6, and a limiting hole 8 is opened on the side panel 7, the limiting hole 8 is in a long strip shape and extends in the front and rear direction, a pin shaft 9 is respectively arranged on the upper left and right sides of the bottom frame 1, and the left and right pin shafts 9 pass through the left and right limiting holes 8 respectively.

[0022] Preferably, the skeleton body 6 includes a pair of fixing rods 10, which are respectively vertically arranged on the left and right sides of the support rod 5, and the top and bottom of the fixing rod 10 are respectively movably connected with an upper rocking arm 11 and a lower rocking arm 12, and the left and right side panels 7 are respectively arranged on the outer sides of the left and right lower rocking arms 12, and the side panels 7 are respectively provided with arc holes 13 connected to the limiting holes 8, and the center of the arc holes 13 coincides with the rotation center of the lower rocking arm 12, and the front end adjacent to the lower rocking arm 12 is movably connected with a driving rod 14, and the front end of the upper rocking arm 11 is movably connected to the middle part of the driving rod 14, and the tops of the left and right driving rods 14 are respectively fixed on the top support rod 15, and the left and right ends of the top support rod 15 are respectively provided with mounting plates 16, and a top frame 17 located above the top support rod 15 is arranged between the left and right mounting plates 16. The left and right sides of the front end of 17 are movably connected with front pull rods 18 respectively, and the bottoms of the left and right front pull rods 18 are movably connected to the front ends of the left and right mounting plates 16 respectively. The left and right sides of the rear end of the top frame 17 are movably connected with rear pull rods 19 respectively, and the bottoms of the left and right rear pull rods 19 are movably connected to the rear ends of the left and right mounting plates 16 respectively. A first connecting rod 20 is provided between the front ends of the left and right lower rocking arms 12, and a linear module 21 is movably connected to the rear side of the first connecting rod 20. A second connecting rod 23 is provided between the left and right side frames of the top frame 17, and a slider 22 of the linear module 21 is movably connected to the lower side of the second connecting rod 23; when working, the motor of the linear module 21 drives the slider 22 to move forward to drive the lower rocking arm 12 to swing to the rear side, and the pin shaft 9 slides into the arc hole 13;

[0023] The motor of the linear module 21 drives the slider 22 to slide, thereby driving the top frame 17 to rise or fall. Figure 1-4 , the top frame 17 is lifted to the highest position, at which time the pin shaft 9 abuts against the bottom inner wall of the arc hole 13. In this state, the skeleton body 6 cannot be shaken forward and backward. The lifting of the top frame 17 can facilitate the user to stand up from the seat. When the top frame 17 is lifted to the highest position, since the skeleton body 6 cannot be shaken forward and backward, the user can stand up from the seat more safely; Figure 5-6 , the top frame 17 drops to the lowest position, at which time the skeleton body 6 can rock back and forth.

[0026] When in use, the skeleton body 6 can be rocked back and forth, that is, it can realize the function of a rocking chair; when the skeleton body 6 is rocked back and forth, Figure 6 When the pin 9 abuts against the rear inner wall of the limiting hole 8, the skeleton body 6 swings forward to the highest position and cannot continue to swing forward. Figure 5 When the pin shaft 9 abuts against the front inner wall of the limiting hole 8, the frame body 6 swings back to the highest position and cannot continue to swing back; the forward and backward swinging amplitude of the frame body 6 is limited, so the seat frame is safer to use and the user is not likely to fall when rocking on the seat; the seat frame of this embodiment has a rocking chair function and is highly safe when used.

[0027] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
