The invention provides an automobile armrest with a heating function. The automobile armrest comprises heating pipe electrical connectors, heating pipe supporting slots and steel rings. A power socketwhich is protruding is installed on the front end surface of a base, and a USB power interface which is of a round-pin structure is penetratingly installed in the middle of the power socket. Circular-structural rubber-band type spring hangers are respectively mounted on the left side and the right side of the bottom surface of the base through rivets, and four cylindrical-structural guide sleevesare uniformly penetratingly distributed downwards from the top surface of the base. Heat effect generated from a heating base plate makes arms placed on the double concave structure warm, especiallyin winter. As the structure is divided into a top part and a bottom part, the heating structure is mounted on the top part, the bottom part refers to a common leather pad type support structure, thus,the armrest structure which can be detached and mounted according to seasons is formed. As the armrest structure can be detached and mounted according to seasons, the armrest has higher practicability.
