The invention relates to the technical field of automobile parts, in particular to a commercial vehicle seat inclination angle adjusting mechanism which comprises a shock absorber assembly and further comprises a toothed plate connecting rod assembly, a rotating frame assembly and a connecting rod. The toothed plate connecting rod assembly is installed in a round hole in the front end of the rotating frame assembly and can rotate relative to the rotating frame assembly, the rear end of the rotating frame assembly is rotationally connected with the shock absorber assembly through a step bolt, the upper end of a connecting rod is rotationally connected with the toothed plate connecting rod assembly and the shock absorber assembly through step bolts, and a four-connecting-rod mechanism is formed. According to the commercial vehicle seat inclination angle adjusting mechanism, the toothed plate and four-connecting-rod structure is adopted, the unlocking direction can be flexibly adjusted through the structure, clockwise unlocking and anticlockwise unlocking can be achieved only by adjusting the assembling direction of the locking cam, modification is small, parts are completely shared, cost does not need to be increased, and the commercial vehicle seat inclination angle adjusting mechanism is suitable for popularization and application. In addition, the mechanism can be shared by manual and electric inclination angle adjusting platforms, investment of part molds and tools is reduced, and compatibility is high.

    本发明涉及汽车配件技术领域,具体为一种商用车座椅倾角调节机构,包括减震器总成,还包括有齿板连杆组件、旋转框总成和连杆;齿板连杆组件安装在旋转框总成前端的圆孔中,可相对旋转框总成转动,旋转框总成后端通过台阶螺栓与减震器总成转动连接,且连杆上端分别通过台阶螺栓与齿板连杆组件和减震器总成转动连接,形成一个四连杆机构,此商用车座椅倾角调节机构,采用齿板和四连杆结构,该结构能够灵活调整解锁方向,既能实现顺时针解锁,也能实现逆时针解锁,只需要调整锁止凸轮的装配方向即可实现,改动小、且零件完全共用,无需增加成本,此外该机构能够实现手电动倾角调节平台共用,减少零部件模具及工装投资,兼容性高。
