description The utility model discloses a variable valve lift rocker arm assembly device, a variable valve lift device and an automobile, one end of a rocker arm body of the rocker arm assembly device is used for being connected with a valve bridge assembly, and the other end of the rocker arm body is in running fit with a cylindrical pin. One end of a movable body support of the roller assembly is matched with the cylindrical pin, and the other end is provided with a roller shaft parallel to the cylindrical pin. Cams of the cam assembly are consistent with the rollers in number, are arranged below the rollers and are parallel to roller shafts. And the return spring is used for enabling the roller assembly to have a downward movement trend, so that the roller is attached to the cam. The number of the linkage structures is consistent with that of the roller assemblies, and the linkage structures are arranged at the positions, corresponding to the roller assemblies, of the rocker arm body and comprise the locking state and
