DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 and Figure 2As shown, an assembled sponge pad comprises an upper sponge pad layer and a lower sponge pad layer; the upper sponge pad layer 3 and the lower sponge pad layer 1 are in a top-to-bottom fitting structure, and a socket 12 is provided at the center of the upper sponge pad layer 3 and the lower sponge pad layer 1, and a screw component is installed in the socket 12; wherein, compared with the previous single-layer paving structure, the upper and lower double-layer sponge structure of the upper sponge pad layer 3 and the lower sponge pad layer 1 can more effectively improve the sound insulation and heat preservation effects, and the position of the screw component can be adapted and replaced in conjunction with other mounting structures on the roof, and can play the role of other internal integrated mounting structures. Compared with the integrated mold opening, which also needs to consider some installation of the interior and the effect of hiding the installation traces, the screw component can improve the use efficiency of the structure and reduce the difficulty of the roof mold opening design.

[0025] The upper surface of the upper sponge cushion layer 3 is covered with a net 14 through a net edge 7; the net 14 plays a gathering effect, and the overall restraint force of the sponge is improved through the net 14.

[0026] The lower surface of the lower sponge cushion layer 1 is limitedly installed with a pressure plate 13 through a screw assembly; the pressure plate 13 further improves the plasticity of the entire sponge, and can be adapted to pressure plates of different curvatures and areas according to the structure of the roof, thereby improving the efficiency of later assembly and reducing the difficulty of assembly. At the same time, the roof of a car can also use multiple sets of screw assemblies, which can be determined according to the interior and other installation requirements.

[0027] The upper sponge cushion layer 3 and the lower sponge cushion layer 1 are bonded and contacted by the adhesive layer 2. The adhesive layer 2 can change the direct bonding mode between the sponges to an intermediate bonding mode, further improving the fault tolerance of sponge bonding, and also improving the recovery rate of subsequent sponge defective products.

[0028] like Figure 1 and Figure 2 As shown, the screw connection assembly includes a screw sleeve 5 and a screw head 10; the screw sleeve 5 is inserted into the insertion hole at the center of the upper sponge cushion layer 3, and the bottom docking port of the inserted screw sleeve 5 is screwed with the screw head 10; the screw head 10 is inserted into the insertion hole 12 at the center of the lower sponge cushion layer 1. The screw connection method of the screw sleeve 5 and the screw head 10 is relatively simple and convenient, and there is no difficulty in operation.

[0029] like Figure 1 and Figure 2 As shown, the top of the screw sleeve 5 is integrally connected with an upper packaging cover 4, and the bottom of the screw sleeve 5 and the inner end surface of the upper sponge cushion layer 3 are clamped with a pressure ring 6; the pressure ring 6 is a limiting structure for further limiting the position of the screw sleeve 5 for installing the screw interface.

[0030] The top of the screw head 10 is integrally connected with a lower packaging cover 11, and the lower packaging cover 11 is in extrusion contact with a pressing plate 13, and the pressing plate 13 is annularly arranged on the lower surface of the lower sponge cushion layer 1 along the insertion hole 12. The combined extrusion method of the lower packaging cover 11 and the pressing plate 13 can further expand the plastic capacity around the screw head 10.

[0031] like Figure 1 and Figure 2 As shown, the inner end surfaces of the upper sponge cushion layer 3 and the lower sponge cushion layer 1 are both pasted with adhesive rings 8, and the two groups of adhesive rings 8 are in a mirror-image pasting structure.

[0032] like Figure 1 and Figure 2 As shown, the upper sponge cushion layer 3 and the lower sponge cushion layer 1 are encapsulated with edge sealing tape 15. The edge sealing tape 15 can further protect the sponge cushion layer, and prevent the sponge cushion layer from loosening from the side due to other factors and partially falling off, which affects the thermal insulation and sound insulation effect of the roof.

[0033] like Figure 1 and Figure 2 As shown, the upper sponge cushion layer 3, the lower sponge cushion layer 1, the adhesive layer 2 and the adhesive ring 8 are all limited to a circular or annular structure.

[0034] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
