As shown in fig. 2 and 4, first grooves 31 are respectively formed on two sides of the decoupling film 3 in the thickness direction, and the first grooves 31 are provided with protrusions 32. Specifically, when the decoupling film 3 is subjected to impact forces of different magnitudes, deformation regions are different, wherein the region where the first groove 31 is located may be a first region, and the region annularly arranged on the periphery of the first region may be a second region, for example, the first region may deform locally at a small amplitude, the first region of the decoupling film 3 may deform, the first region and the second region may deform simultaneously at a large amplitude, the protrusion 32 may have a structure such as a cylinder, a polygonal prism, a tapered column, and the like, so that a small-area point contact between the decoupling film 3 and the upper flow channel plate 1 and the lower flow channel plate 2 is realized. Wherein, decoupling zero membrane 3 can be the rubber spare, and when decoupling zero membrane 3 took place to deform, arch 32 also can take place to deform to can improve decoupling zero membrane 3's deflection, avoid decoupling zero membrane 3's dynamic stiffness increase, improve decoupling zero structure 100's vibration isolation performance.

According to some embodiments of the present invention, as shown in fig. 4, the protrusion 32 is plural. This arrangement can ensure the deformability of the first groove 31, and improve the vibration isolation performance of the decoupling structure 100. The number of the protrusions 32 on the two sides of the decoupling film 3 in the thickness direction may be different, and the positions may be staggered.

According to some embodiments of the present invention, as shown in fig. 4, the protrusions 32 in the first groove 31 are uniformly arranged in the first groove 31. Specifically, the number of projections 32 in the two first grooves 31 is equal, and the positions may be opposite in the thickness direction of the decoupling film 3.

This arrangement allows the area of the boundary between the first recess 31 and the second recess 33 to be reduced, so that a small impact of the decoupling film 3 with the upper flow field plate 1 and the lower flow field plate 2 can be better avoided when the vehicle is idling. Under the bad working conditions such as bumpy road sections, the buffer effect on the impact action can be improved, the impact strength of the decoupling film 3 and the upper flow channel plate 1 and the lower flow channel plate 2 is reduced together with the protrusions 32, abnormal sound generated by impact is further reduced, and riding experience of passengers is better improved.
