Lifting driving mechanism and information acquisition module

The lifting driving mechanism comprises a base, a lifting frame, a driving connecting rod mechanism, a transmission connecting rod mechanism and a driving device, wherein the base and the lifting frame are oppositely arranged up and down; the driving connecting rod mechanism is hinged to the base; the transmission connecting rod mechanism is located between the base and the lifting frame; and the other end of the transmission connecting rod mechanism is fixedly connected with the lifting frame. The driving device is used for driving the driving connecting rod mechanism to rotate so as to drive the transmission connecting rod mechanism and the driving connecting rod mechanism which are hinged to each other to stretch or compress. The utility model further provides an information acquisition module applying the lifting driving mechanism. 本申请公开一种升降驱动机构，该升降驱动机构包括上下相对设置的底座和升降框、铰接于底座上的驱动连杆机构、位于底座和升降框之间的传动连杆机构以及位于底座上且连接驱动连杆机构的驱动装置。传动连杆机构的一端与驱动连杆机构铰接且另一端固定连接升降框。驱动装置置用于驱动所述驱动连杆机构转动以带动相互铰接的所述传动连杆机构和所述驱动连杆机构进行伸展或者压缩。本申请
