[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0016] like Figures 1-2 The seat folding mechanism shown includes a fixed plate 1, a connecting rod 2, a movable rod 3, a connecting shaft 4, a fixed seat 5, a first support rod 6, a second support rod 7, and a base 8. The fixed plate 1 has a bottom plate 11 and a side plate 12. The upper and lower ends of the first support rod 6 and the upper and lower ends of the second support rod 7 are respectively hinged to the side plate 12 and the base 8. The first support rod 6 and the second support rod 7 are arranged in parallel.

[0017] The fixed base 5 is fixedly connected to the lower plane of the base plate 11. One end of the connecting rod 2 is hinged to the second support rod 7, and the other end is hinged to the side plate 12 via the connecting shaft 4. The connecting shaft 4 extends into the fixed base 5. Figure 3As shown, the fixed base 5 has a set of stepped holes along the axial direction, namely a spring hole 51 and a connecting shaft through hole 52. The diameter of the spring hole 51 is larger than that of the connecting shaft through hole 52. The other end of the connecting shaft 4 passes through the spring hole 51 and the connecting shaft through hole 52 in sequence and is axially limited by the pin 10 to the side of the fixed base 5 away from the connecting rod 2. A spring 9 is sleeved on the connecting shaft 4 and the spring 9 is disposed in the spring hole 51.
