Description

  The present invention relates to a vehicle floor raising material that is arranged on a floor pan of an automobile and sets the height of the floor surface.

  Conventionally, as described in Patent Document 1, a flooring material is disposed on a floor pan, and a floor surface is formed by laying a carpet thereon, and the height of the floor surface is set to a desired height. In addition, those that improve soundproofing and sound insulation are known. And as a raising | lifting material, as described in patent document 1, what consists of a hollow double-wall structure by blow molding, what is comprised by the foam described in patent documents 2 and 3, Furthermore, patent document 4 describes There is a plastic one formed by injection molding or the like, and it has been studied to support and form a wire harness or a floor duct arranged under the floor.

Patent Document 2 discloses that a long groove for accommodating a wire harness and a duct groove for inserting a blowing duct extending rearward from the front of the air conditioner are formed below the raising member. Patent Document 3 discloses a configuration in which an air passage is formed between the front seat lower raising member and the rear seat raising member, and hot air can be blown to the rear seat side by connecting a heater duct. Has been. Japanese Patent Application Laid-Open No. H10-228667 discloses a material having an excellent effect that it is not necessary to set a heater duct as a separate member by forming a heater duct portion on the raising material and is inexpensive.

  However, the raising materials disclosed in Patent Documents 2 and 3 have a duct groove or an air passage, but separate ducts are required. From the viewpoint of modularization, the raising material and the duct Assembling work is complicated, which is not preferable. Further, the raising material disclosed in Patent Document 4 is integrally formed with a heater duct portion, and the heater duct portion has an undercover vehicle width curved along the upper surface of the floor tunnel portion at the lower portion of the raising material. It is designed to extend in the vehicle front-rear direction to the left and right of the floor tunnel with the outer edge in the direction coming into contact. There is a problem that a serious limitation occurs.

  Accordingly, the present invention addresses the above-described problems, and the raising material has a hollow double wall structure including an upper surface wall and a back wall, and protrudes from the back wall toward the hollow portion. The first concave groove and the second concave groove are integrated with the upper surface wall at the welded portion, and a duct portion having an air flow path isolated from the hollow portion of the raising material is provided between the concave grooves. Therefore, in the floor structure of an automobile, the raising material and the duct portion are integrated to reduce the number of parts, and it is suitable for modularization of vehicle parts. Moreover, the vehicle floor raising material has a lightweight and sufficient rigidity with a hollow double wall structure. Is to provide.

  The vehicle floor raising material of the present invention that achieves the above object is a vehicle floor raising material that is arranged on a floor pan of an automobile and sets the height of the floor surface, and the raising material comprises an upper surface wall and a back surface wall. A hollow double wall structure, wherein the first groove and the second groove protruded from the back wall to the hollow portion side are integrated with the upper surface wall at the welded portion, A duct portion having an air flow path isolated from the hollow portion of the raising material is provided between the second concave grooves.

  According to the present invention, in the above structure, the upper surface wall is formed with a concave portion corresponding to the first concave groove and the second concave groove, the depth of the concave portion is 10 mm or less, and the duct portion is It is preferable to have an air inlet for rising from the side surface of the raising material and introducing air-conditioned air from the air-conditioning unit.

  According to the present invention, the raising material has a hollow double wall structure composed of the top wall and the back wall, and the first groove and the second groove that protrude from the back wall toward the hollow portion are formed on the top wall. By integrating the welded portion and providing a duct portion having an air flow path isolated from the hollow portion of the raised material between the concave grooves, the raised material and the duct portion are integrated in the automobile floor structure. It is possible to obtain a vehicle floor raising material which is suitable for modularization of vehicle parts by reducing the number of parts and which is light and sufficiently rigid with a hollow double wall structure.

  FIG. 1 is an overall perspective view showing a vehicle floor raising material of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG.

  The vehicle floor raising material of the present invention is used by being disposed over a front wall surface below a dashboard of an automobile and a concave portion of a floor surface continuous therewith. The raising material 1 constituting the vehicle floor raising material has a raised portion 2 corresponding to a concave portion of the floor surface and a footrest portion 3 corresponding to a front wall surface below the dashboard, and is integrally configured.

  And the said raising material 1 has the hollow double wall structure which consists of the upper surface wall 4 and the back surface wall 5, The 1st ditch | groove 7 protruded from the back surface wall 5 to the hollow part 6 side, and 2nd An air flow path that is integrated from the hollow portion 6 of the raising material 1 between the first concave groove 7 and the second concave groove 8. A duct portion 11 having 10 is provided. Further, the upper surface wall 4 is formed with concave portions 12 corresponding to the first concave groove 7 and the second concave groove 8, respectively, and the depth of the concave portion 12 is 10 mm or less, and the concave portion 12. The width of the opening is 10 mm or less. The duct portion 11 rises from the side surface of the raising material 1, has an intake port 13 for introducing air-conditioned air from the air conditioner unit, and has an exhaust port 14 opened on the rear side surface of the raising material 1. is doing. Air-conditioned air of the air-conditioning unit can be sent from the exhaust port 14 to the rear seat. Reinforcing ribs 15 are formed on the upper wall 4 and the portion of the duct portion 11 that constitutes the air flow path 10 (see FIG. 1). Reference numeral 16 denotes a carpet (see FIG. 2).

  The raising material 1 is made of a thermoplastic resin such as an ABS resin, a modified polyphenylene oxide resin, a polycarbonate resin, a polyamide resin, a polystyrene resin, a polyethylene resin, or a polypropylene resin.

  The raising material 1 configured as described above forms the recessed portion 12 from the upper surface wall 4 side, and the first recessed groove 7 and the second recessed groove 8 formed from the back wall 5 are integrated with the welded portion 9. Therefore, the moldability and the rigidity of the raising material are improved. In addition, since the depth of the recessed portion is 10 mm or less, the flatness of the raising material 1 on the side of the upper surface wall 4 is improved and the passenger does not feel uncomfortable.

It is a whole perspective view which shows the raising material for vehicles of this invention. It is AA sectional drawing in FIG.
