The invention relates to an automobile back door vibration absorber. The automobile back door vibration absorber comprises a mounting assembly and a vibration absorption component arranged in the mounting assembly, and is characterized in that the mounting assembly comprises a mounting support, a limiting wall and two penetration welding bolts; the mounting support is in a capital-omega-shaped andis provided with a rear vertical face, a left side vertical face and a right side vertical face, and the limiting wall is connected with the inner side of the rear vertical face in an attached mode;supporting lugs folded outwards are arranged on the lower edges of the two side vertical faces respectively, penetration welding holes are formed in the middles of the supporting lugs correspondingly,and the penetration welding bolts penetrate through the penetration welding holes to be connected with mounting nuts on inclined reinforcing ribs arranged on the lower portion of a back door inner plate in a matched mode; the rear face of the vibration absorption component corresponds to the inner side of the rear vertical face, and the left side face and the right side face of the vibration absorption component are connected with the inner sides of the left side vertical face and the right side vertical face of the mounting support respectively. According to the automobile back door vibration absorber, repeated performance parameter matching and test verification can be avoided, and the product development speed is increased; ear pressing sound of the back door is avoided, and the back door modality is improved.
