The invention discloses an automobile steering column assembly and a collapse energy absorbing device thereof. The collapse energy absorbing device comprises an installation support fixedly connected with an automobile body and a pull and release lock connected with the installation support and further comprises an adjustment mechanism support connected with an upper column pipe. A guide groove is formed in the installation support. A guide wheel is installed in the guide groove in a sliding manner and fixedly connected with the adjustment mechanism support through a fixing bolt. The installation support and the pull and release lock are fixedly connected through a fastener. The pull and release lock is connected with the adjustment mechanism support through a collapse piece. Therefore, the collapse energy absorbing device cannot be separated from the installation support in the collapse process, a steering wheel is prevented from falling excessively when a steering column collapses, the safety of the legs of a driver is guaranteed, and the buffering performance is improved through sliding movement between the guide wheel and the guide groove.
