Flexible structure, flexible structure for air conditioner air channel assembly and air conditioner

The invention discloses a flexible structure, a flexible structure for an air conditioner air channel assembly and an air conditioner. The air conditioner air channel assembly comprises a volute and avolute cover. The flexible structure is arranged additionally in the direct-contact position of the volute and the volute cover. Sealing and / or noise reduction is conducted on the volute and the volute cover by the flexible structure. According to the technical scheme of the flexible structure for the air conditioner air channel assembly, after the volute and the volute cover are assembled, under a heating working condition, abnormal sounds are generated by thermal expansion extrusion; the part of buffering and reducing force can be played by a soft-structure material in collision and stress of a hard material; and thus the flexible structure is arranged additionally in the direct-contact position of the volute and the volute cover. Two-component polyurethane adhesive tape is adopted bythe flexible structure, a
