Drawings
Fig. 1 is a schematic cross-sectional structure view of a vehicle floor mounting structure provided by the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
As shown in fig. 1, the present embodiment provides a vehicle floor mounting structure applied to mounting between a vehicle body floor 5 and an aluminum honeycomb floor 1.
The vehicle floor mounting structure comprises a plurality of shock absorbing members 4 and a filling layer 3, wherein the shock absorbing members 4 are arranged at intervals along the vehicle floor.
