Technical Field

[0001] The utility model relates to the technical field related to fuel tank heat insulation boards, in particular to a fuel tank heat insulation board structure for an automobile. Background Art

[0002] China is the world's largest automobile market with the greatest potential for automobile consumption. With the development of social economy, the improvement of people's living taste, and the emergence of new consumption patterns such as self-driving travel and camping, people's demand for off-road vehicles is increasing.

[0003] Off-road vehicles refer to vehicles that are suitable for harsh road environments and outdoor driving. They are suitable for harsh environments such as climbing hills and wading. Off-road vehicles usually use four-wheel drive and can travel on roads of very poor quality or in areas where there are no roads at all. In order to achieve four-wheel drive, a saddle-type fuel tank is usually designed, and the rear-wheel drive drive shaft and exhaust pipe pass through the bottom of the fuel tank. In order to avoid the heat of the exhaust pipe from having an adverse effect on the fuel tank, a heat shield is usually added between the fuel tank and the exhaust pipe, and the heat shield is fixed to the fuel tank; off-road vehicles often encounter wading and other operating conditions during use, and the impact of water flow on chassis components causes damage. It is usually strengthened by increasing the thickness of the protective plate, which leads to an increase in the vehicle's own weight and cost. Utility Model Content

[0007] As a preferred technical solution of the utility model, the heat insulation board body is provided with an inwardly recessed cavity for the transmission shaft and the air pipe to pass through, and both ends of the cavity are open.

[0008] As a preferred technical solution of the utility model, the fixing seat is a plastic part and is welded to the surface of the automobile fuel tank.

[0009] As a preferred technical solution of the present utility model, the main body of the heat insulation board is a metal plate with a thickness not greater than 1.00 mm.

[0010] As a preferred technical solution of the utility model, the automobile fuel tank is a plastic or metal part.

[0011] As a preferred technical solution of the utility model, a plurality of unloading holes are provided.

[0012] As a preferred technical solution of the utility model, the periphery of the heat insulation board body is provided with a flange structure.

[0013] The beneficial effects of the utility model are:

[0014] The automobile fuel tank heat insulation board structure is provided with a unloading hole at the bottom of the heat insulation board body to reduce the impact force of water flow on the heat insulation board, thereby preventing damage to the fuel tank heat insulation board caused by the vehicle wading; thus, a thinner heat insulation board can be selected to achieve higher social and economic benefits.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1 , Figure 2 , Figure 3As shown, the utility model is a heat insulation board structure for a fuel tank of an automobile, comprising a fuel tank 1 and a heat insulation board body 2. The bottom of the fuel tank 1 is provided with a mounting groove 3 which is inwardly recessed and matches the outer contour of the heat insulation board body 2, and the bottom of the fuel tank 1 is provided with a fixing seat 4, and the heat insulation board body 2 is fixed to the fixing seat 4 by bolts, and the bottom of the heat insulation board body 2 is provided with a unloading hole 6. The unloading hole 6 is provided at the bottom of the heat insulation board body 2 to reduce the impact force of water flow on the heat insulation board, thereby preventing damage to the fuel tank heat insulation board caused by the vehicle wading; thus, a thinner heat insulation board can be selected to achieve higher social and economic benefits. The heat insulation board body 2 is provided with knurling.

[0022] The heat insulation board body 2 is provided with a concave cavity 7 which is recessed inwards and through which the transmission shaft and the air pipe pass, and both ends of the concave cavity 7 are open. In this way, there will be no collision with the transmission shaft and the air pipe.

[0023] The fixing seat 4 is a plastic part and is welded to the surface of the automobile fuel tank 1 , so as to facilitate fixing the fixing bracket and the automobile fuel tank 1 .

[0024] The heat insulation board body 2 is a metal plate with a thickness of no more than 1.00 mm, so that the thickness of the heat insulation board body 2 is relatively thin, thereby reducing the overall quality. A thinner heat insulation board can be selected to achieve higher social and economic benefits.

[0025] The automobile fuel tank 1 is a plastic or metal part, usually in a box shape or a special shape, and is used to store the fuel required for the vehicle to travel.

[0026] There are multiple unloading holes 6 .

[0027] The heat insulation board body 2 has a flange structure 5 around its periphery.

[0028] When working, the automobile fuel tank heat insulation board structure is provided with a unloading hole 6 at the bottom of the heat insulation board body 2 to reduce the impact force of water flow on the heat insulation board, thereby preventing the fuel tank heat insulation board from being damaged when the vehicle wades through water; thus, a thinner heat insulation board can be selected to achieve higher social and economic benefits.
