Of course, instead of overlapping the protrusions 302 on both sides in the thickness direction of the decoupling film 3, the protrusions 302 on both sides may be arranged so as to be staggered. In addition, the number, shape, and size of the protrusions 302 on both sides may be different in addition to the same, and the size and shape of the protrusions 302 on each side may be different.

Here, instead of the projection 302102 being cylindrical, it may be rectangular, triangular, or the like.

By adopting the above structure, when the power assembly vibrates greatly, the damping liquid impacts the decoupling film 3 to cause the decoupling film 3 to vibrate up and down, at this time, gaps are formed between the decoupling film main body 301 and the upper runner plate 2 and the lower runner plate 1, the decoupling film main body 301 cannot contact with the upper runner plate 2 and the lower runner plate 1, and only the protrusions 302 can contact with the upper runner plate 2 and the lower runner plate 1. Moreover, the bulge 302 can freely move in the mounting groove P, and the end part of the bulge 302 contacts with the upper runner plate 2 or the lower runner plate 1, so that the bulge 302 has a smaller contact area due to the conical shape of the end part, and abnormal sound generated by the decoupling film 3 striking the upper runner plate 2 and the lower runner plate 1 due to large vibration can be reduced or even avoided, thereby being beneficial to improving the quality of the whole vehicle.
