[0015] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1 and Figure 2 As shown, a seat pitch posture adjustment structure includes a sliding bracket 2, which is fixed on a base, and an automatic driving component is provided at the tail of the sliding bracket 2. A slidable chair body side frame 1 is provided on the outside of the sliding bracket 2, and the chair body side frame 1 is restricted by limiting mechanisms on both sides of the top and tail of the sliding bracket 2. When in use, the automatic driving component drives the chair body side frame 1 to slide, and the sliding process is guided by the sliding groove.

[0017] The limiting mechanism includes a sliding limit shaft 3 and a sliding groove. The sliding limit shaft 3 is fixed on both sides of the top of the base and placed in the corresponding groove body of the chair side frame 1. The sliding groove is arranged on both sides of the tail of the base. The shaft body at the corresponding position of the chair side frame 1 is placed in the sliding groove. The chair side frame 1 slides in a circular arc trajectory through the guidance of the sliding groove and the groove body, and is limited by the limit shaft during the sliding process.

[0018] The sliding groove and the groove body are both arc-shaped, ensuring that the sliding is carried out along an arc track.

[0019] The driving component includes a chair body screw 5, the tail of which is movably connected to the base and is sleeved with the motor on the chair body side frame 1. When the motor is started, the motor moves along the chair body screw 5, and at the same time drives the chair body to move.

[0020] A chair body bracket 4 is fixed to the tail end of the sliding bracket 2 , and the seat is supported by the chair body bracket 4 .

[0021] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity from another entity, but do not necessarily require or imply any actual relationship or order between these entities.
