Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be clearly and completely described in the following in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model discloses a front-guard single-piece air guide pipe which is suitable for a vehicle type with a front wheel arch. The single-piece air guide pipe shown in fig. 1 consists of an air guide pipe body 1, a sealing foam 2 with back glue and a lower sealing foam 3 with back glue, a plurality of ribs 9 are added on the back surfaces of an upper bonding surface and a lower bonding surface which are buckled with the inner side of a front protective skin, and the ribs 9 are arranged in the vertical direction instead of integrally penetrating through the ribs as shown in fig. 2, so that the strength of the bonding surface is enhanced, deformation is prevented, and the weight of a single piece is reduced.

As shown in fig. 3, a fog lamp wire harness fixing hole 6 is added at a bulge position on one side of the single-piece air guide pipe and is fixedly used by a wire harness clip, and a wheel cover lining upper mounting hole 7 and a wheel cover lining lower mounting hole 8 are arranged at the rear end of the single-piece air guide pipe, so that a fixing function is provided.

In the embodiment, the single-piece air guide pipe protrudes to one side, the section of the single-piece air guide pipe is C-shaped, and the single-piece air guide pipe is buckled with the inner wall of the front bumper to form a channel; the front side of the front bumper is provided with a guide port, and meanwhile, a fog lamp cover plate is also provided with a reverse port and is fixed on the front side of the front bumper in a clamping and screwing manner; the front end of the air deflector is matched with the guide opening of the front bumper, the rear end of the air deflector is matched with the opening of the wheel cover lining plate, a front-to-back airflow channel is formed, airflow can flow backwards through the formed channel in the running process of the whole automobile, and the effects of reducing the wind resistance of the whole automobile and cooling the front wheel hub are achieved.
