Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration parts, in particular to a front floor mat of an automobile. Background Art

[0002] During the automobile manufacturing process, shock-absorbing pads, sound-insulating pads and carpets are usually laid on the automobile floor sheet metal. The combination of the three forms a mat that can simultaneously play the functions of shock absorption, sound insulation and beautification of the interior, and plays an important role in the comfort experience of drivers and passengers. In the prior art, shock-absorbing pads, sound-insulating pads and carpets are usually manufactured separately and then assembled together by gluing or other means. The cumbersome assembly process limits its manufacturing efficiency, and a large amount of glue is required during gluing, and the environmental protection requirements for the glue layer material are also high.

[0003] The technical solution disclosed in the patent entitled "Automobile Sound Insulation and Sound Absorption Mat Structure" (CN101570151A) includes an upper waterproof layer, a lower sound absorption layer and a carpet layer, and each layer of components is bonded and integrally formed by molding technology. This solution can achieve a good sound insulation effect, but the foam material in the middle layer of the mat is also connected to the other layers by gluing the glue layer, and the assembly process is cumbersome. Utility Model Content

[0004] The utility model aims to provide a front floor mat for an automobile, which is integrally formed by a foaming technology to reduce the assembly process of the mat.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a car front floor mat, which is arranged above the front floor sheet metal and consists of a top layer of carpet, a middle layer of sound insulation pad and a bottom layer of shock-absorbing pad, the sound insulation pad is made of foam material, and the carpet, sound insulation pad and shock-absorbing pad are integrally formed by foaming technology.

[0006] The utility model mainly forms the carpet, sound insulation pad and shock absorption pad of the tread mat in one piece through foaming technology, so that the tread mat can be directly assembled on the front floor sheet metal. No glue layer is required between the carpet, sound insulation pad and shock absorption pad of the utility model, and the process of bonding the three is omitted, which saves materials and reduces the assembly process, thereby improving production efficiency.

[0010] Figure 4 It is a cross-sectional view of the front floor mat of a car. DETAILED DESCRIPTION

[0011] See also Figure 1-4 The car front floor mat shown in the figure is arranged above the front floor sheet metal A. The car front floor mat 1 is composed of a top layer of carpet 10, a middle layer of sound insulation pad 20 and a bottom layer of shock-absorbing pad 30. The sound insulation pad 20 is made of foam material, and the carpet 10, the sound insulation pad 20 and the shock-absorbing pad 30 are integrally formed by foaming technology.

[0012] In the above scheme, the carpet 10 and the shock-absorbing pad 30 are first formed independently, and then the two are simultaneously placed in the foaming mold of the sound insulation pad 20 for foaming together. After the sound insulation pad 20 is foamed, it is formed as a whole with the carpet 10 and the shock-absorbing pad 30, that is, the sound insulation pad 20 is connected to the upper carpet 10 and the lower shock-absorbing pad 30 at the same time under the action of the foaming process, and the three no longer need to be glued or assembled together in other ways. In addition, the front floor mat 1 can be supplied as a whole during the vehicle assembly process, instead of the traditional process where the carpet 10, the sound insulation pad 20 and the shock-absorbing pad 30 are supplied separately, which reduces transportation and assembly costs and improves production efficiency.

[0013] The carpet 10 and the shock-absorbing pad 30 are completely separated by the sound-insulating pad 20. Since the carpet 10, the sound-insulating pad 20 and the shock-absorbing pad 30 are integrally formed by foaming technology, the sound-insulating pad 20 composed of the foaming material plays a role in adhering the upper and lower layers in the middle layer. Therefore, the sound-insulating pad 20 composed of the foaming material must be completely filled in the gap between the upper carpet 10 and the lower shock-absorbing pad 30. The carpet 10 and the shock-absorbing pad 30 cannot contact each other during the foaming molding process, otherwise, the surface of the carpet 10 and the shock-absorbing pad 30 that are in direct contact will not be able to adhere to each other due to the lack of filling of the foaming material.

[0014] In order to reduce material costs while ensuring the shock absorption effect, the shock absorption pad 30 is composed of a first shock absorption pad 30A and a second shock absorption pad 30B, and the first shock absorption pad 30A and the second shock absorption pad 30B are respectively arranged at the foot pedals of the front cockpit and the co-pilot cabin. In the above scheme, the first shock absorption pad 30A and the second shock absorption pad 30B are located under the feet of the front seats and the front passengers, and the parts such as the central channel of the car that are not covered by the shock absorption pad 30 are not in the seating area of ​​the passengers. Therefore, the design of this scheme can save materials and space while still ensuring the shock absorption experience of the front passengers when the vehicle is driving.

[0015] In order to assemble the automobile front floor mat 1 on the front floor sheet metal A, the bottom surface of the automobile front floor mat 1 is coated with an adhesive layer, and the bottom surface of the automobile front floor mat 1 is connected to the front floor sheet metal A by adhesive bonding.

[0016] As a more preferred embodiment, the automobile front floor mat 1 is pressed onto the front floor sheet metal A. The bottom surface of the front floor mat 1 matches the top surface of the front floor sheet metal A, and the pressing and fixing method saves glue and is more environmentally friendly, and does not produce glue odor.

[0017] Preferably, the carpet 10 is made of a composite of three materials: PET, EVA and PE; the sound insulation pad 20 is made of foamed PU material; and the shock-absorbing pad 30 is made of EVA material.
