Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Example one

The flat air inlet pipe assembly of the light truck is used as an important component of an air inlet system, is fixedly arranged on a cab and is mainly used for providing air inlet. The flat air inlet pipe assembly of the present embodiment structurally includes a flat pipe housing 1, the flat pipe housing 1 has an air inlet, the air inlet is provided with an air inlet grille 11, the air inlet grille 11 is riveted to the middle upper portion of the flat pipe housing 1 by rivets, air enters the flat pipe housing 1 through the air inlet grille 11, the flat pipe housing 1 has an air outlet, the air outlet adopts an air outlet port 12 located at the bottom of the flat pipe housing 1, and the air outlet port 12 is communicated to an air filter through a corrugated pipe.

Flat pipe shell 1 is the core of air intake flat pipe, not only will reduce the air intake resistance of inner wall, will prevent again that the engine from inhaling the deformation with flat pipe at the in-process of breathing in, consequently this embodiment has carried out a series of optimizations to flat pipe shell 1's structure and material equally: in terms of materials, the flat tube shell 1 is made of HDPE (high density polyethylene), and the materials are outstanding in chemical stability, rigidity, toughness, mechanical strength and the like. Considering that the air input is the most important index of flat tube housing, consequently this embodiment does the casing inner space big when designing flat tube housing 1, reduces inside unevenness's place as far as possible, reduces the air intake resistance. Secondly, considering that the suction force of the air inlet of the engine is very large, in order to prevent the flat pipe from being sucked flatly, three transverse reinforcing ribs 13 are additionally arranged on the front surface of the flat pipe shell 1, a longitudinal reinforcing rib 14 is additionally arranged on the back surface of the flat pipe shell, two supporting cross beams 15 are additionally arranged inside the flat pipe shell, and two ends of each supporting cross beam 15 are fixedly connected with the inner wall of the flat pipe shell 1 respectively, so that the flat pipe of the air inlet can be effectively prevented from being sucked flatly and deforming.

In terms of air intake, the present embodiment performs the following optimization design on the air intake grille 11 of the air intake: the opening area of the air inlet grille is increased, so that the air inlet grille originally only spans two surfaces of the flat pipe shell 1 at one opening, namely the air inlet grille 11 is positioned at the junction of transition connection of two side surfaces of the flat pipe shell 1, air inlet at two sides is achieved simultaneously, and air inlet amount of all engines matched with the light truck is met. Secondly, considering that the working condition environment of the running vehicle is changeable, the opening direction of the air inlet grille 1 adopts an angle of 45 degrees downwards in an inclined mode, and the design can ensure that enough air inflow enters the pipe to the maximum degree and simultaneously reduces the entering amount of rainwater, sand grains and dust. In addition, the material of the intake grill 11 in this embodiment is a PP (polypropylene) material, which has a low density, a rigid strength, and a good hardness and heat resistance, and is most suitable as the material of the intake grill.

Considering air inlet flat tube's installation problem, this embodiment adopts three point fixation's mode in air inlet flat tube's design, includes the first mounting hole 1a of reserving in flat tub of casing 1 top to and the second mounting hole 1b and the third mounting hole 1c of reserving of lower part, in order to guarantee fixing on the driver's cabin that flat pipe can be stable. Meanwhile, the rear periphery of the cab is protruded, so that one side of the rear part of the flat pipe is designed into an inclined surface under the condition of not changing the cab, and the flat air inlet pipe is ensured not to have any interference problem with the assembly of the cab.

Considering that the flat air inlet pipe always has more or less entry points for rainwater or dust during the running process of the vehicle, a dust exhaust port is reserved below the flat pipe shell 1 of the embodiment, and a dust exhaust bag 16 is mounted at the dust exhaust port, so that rainwater and dust entering the flat air inlet pipe can be conveniently exhausted.

Compared with the air inlet flat pipe of the traditional air inlet system, the air inlet flat pipe assembly of the light truck has the following beneficial effects:

1. the two side areas of the air inlet grille are enlarged, so that the air inlet amount can be effectively provided, and the normal operation of the engine is ensured.

2. The dust exhaust bag is additionally arranged on the lower portion of the air inlet flat tube, so that rainwater and dust can be effectively removed by a vehicle in rainy days and windy days, and clean air is provided for an engine.

3. The flat tub of casing's of admitting air design can solve the flat problem of admitting air and being inhaled the flat effectively and reduce the air resistance of admitting air.

In summary, although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the utility model.
