The invention discloses a leg support adjusting structure of an automobile seat. The structure comprises a pair of mounting plates, a pair of connecting rod assemblies and a leg support assembly, wherein the connecting rod assemblies are arranged on the mounting plates, one ends of the connecting rod assemblies are hinged to the mounting plates on the corresponding sides, and the leg support assembly is arranged at the other ends of the two connecting rod assemblies and extends through the connecting rod assemblies. A fixed beam is connected between the two mounting plates; a pair of hinge plates is mounted on the fixed beam; a driving device is hinged between the two hinge plates; a driving beam is fixed between the two connecting rod assemblies; a pair of driving plates is mounted on thedriving beam; hinge holes are formed in the two driving plates; the driving device comprises a screw rod seat hinged with the two hinge plates, a screw rod which is rotatably arranged on the screw rod seat and extends forwards, a motor which is arranged beside the screw rod seat and drives the screw rod to rotate, and a sliding block of which the middle part is screwed on the screw rod and can move along a length direction of the screw rod; and the two ends of the sliding block are rotatably embedded in the hinge holes in the corresponding sides through bosses. A problem that an extension range of the leg support is limited by the length and angle of the screw rod is eliminated; and a connecting structure is simplified, and assembling efficiency is improved.

    一种汽车座椅的腿托调节结构,包括一对安装板、一对设在安装板上且一端与对应侧安装板铰接的连杆组件和一设在两连杆组件另一端并通过连杆组件伸展的腿托组件,特点:两安装板之间连接有固定梁,固定梁上安装一对铰接板,两铰接板之间铰接有驱动装置,两连杆组件之间固定有驱动梁,驱动梁上安装一对驱动板,两驱动板上开设有铰接孔,驱动装置包括一与两铰接板铰接的螺杆座、一旋转地设置在螺杆座上并向前延伸的螺杆、一设置在螺杆座一旁并驱动螺杆旋转的电机和一中部旋配在螺杆上并能沿螺杆的长度方向移动的滑块,滑块的两端通过凸台旋转地嵌设在对应侧的铰接孔内。消除了腿托伸展范围受螺杆长度及角度限制的问题;简化连接结构,提高组装效率。
