[0016] In the figure, the marks are: 10 - cavity structure reinforcing block, 20 - foam connecting component, 21 - first foam block, 211 - first clamping protrusion, 22 - second foam block, 221 - second clamping protrusion. Detailed Description of the Embodiment

[0017] Next, with reference to the drawings, through the description of the embodiments, the specific embodiments of the present invention will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0018] Figure 1It is a schematic structural diagram of the fixing structure of the internal cavity sealing foam part of an automobile in the embodiment of the present utility model.

[0019] As Figure 1 shown, the fixing structure of the internal cavity sealing foam part of the automobile provided by the present utility model includes a cavity structure reinforcing block 10 and a foam connecting component 20 arranged between the cavity structure reinforcing blocks 10. The cavity structure reinforcing block 10 is filled in the internal cavity of the automobile, and the foam connecting component 20 is arranged between the cavity structure reinforcing blocks 10. The foam connecting component 20 can utilize the resilience characteristics of its own foam material to facilitate the assembly of the cavity structure reinforcing block 10, improve the assembly efficiency, and reduce the cost.
