Description
Technical Field
The utility model relates to a motor vehicle spare part technical field especially relates to an air inlet hose for car.
Background
The automobile as a modern vehicle is entering thousands of households, and the pollution problem of automobile exhaust is also a problem which needs to be solved urgently in the current society. As shown in FIG. 3, one of the air inlet hoses in the air inlet system of the light truck is a pure rubber pipe lined with a steel wire skeleton structure, and the inner and outer walls of the air inlet hose are rough and uneven, and the dimensional accuracy is difficult to conform to the design dimension, so that the air inlet hose has the defect of difficult installation; the other type is a mould pressing pipe which is locally provided with a simple structure and the inner wall of which is of a wave-shaped curve structure. The air inlet hose with the two structures has uneven or wavy inner wall, increases air inlet resistance, and has great disturbance effect on airflow direction, so that airflow inertia effect and airflow pressure fluctuation effect in the air power in the air inlet hose cannot reach the expected design concept.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an air inlet hose for car to reach and increase the aeration quantity, to the undisturbed effect of air current flow direction, increase the purpose of air current inertia effect.
The utility model provides an air inlet hose for automobiles, which comprises a hose body and mounting interfaces at two ends, and is characterized in that the inner wall of the hose body is smooth, and the outer wall of the hose body is provided with an arc-shaped boss and a flat boss; the circular arc-shaped bosses and the flat bosses are longitudinally arranged in parallel at intervals; the two sides of the flat boss are connected with the circular arc boss through connecting rings.
Further, the radius of the circular arc-shaped boss is 6-7 mm larger than that of the hose body, the radius of the flat boss is 2-3 mm larger than that of the hose body, and the radius of the connecting ring is the same as that of the hose body.
Further, the width of the circular arc-shaped boss is 9.5mm-11mm, the width of the flat boss is 7.5mm-10mm, and the width of the connecting ring is 2.5mm-3.5 mm.
Further, the hose body, the arc-shaped boss, the flat boss and the connecting ring are formed in a one-step vulcanization mode.
The utility model provides an automobile is with hose that admits air, the inner wall of hose body is smooth, does not have and is wave type curve, avoids the inner wall unevenness, to the no disturbance effect of air current flow direction, can reduce the air resistance, reduces the interference of admitting air, improves the effect of admitting air. The outer wall of hose body is provided with convex boss and flat boss, and convex boss and flat boss are vertical parallel alternate setting, and the both sides of flat boss are connected with convex boss through the go-between, can strengthen the pliability of hose body, increase the aeration quantity, increase air current inertia effect. Therefore, the utility model discloses can reduce the air current resistance, reduce the interference of admitting air, improve the effect of admitting air, have the increase aeration quantity, to the undisturbed effect of air current flow direction, increase the positive effect of air current inertia effect.

Detailed Description
As shown in fig. 1 and 2, the air inlet hose for the automobile provided by the utility model comprises a hose body 1 and mounting interfaces at two ends, wherein the inner wall of the hose body 1 is smooth, and the outer wall of the hose body 1 is provided with an arc boss 2 and a flat boss 3; the circular arc bosses 2 and the flat bosses 3 are longitudinally arranged in parallel at intervals; the two sides of the flat boss 3 are connected with the circular arc boss 2 through the connecting ring 4.
The utility model discloses when using, at first, hose body 1's both ends are connected with air cleaner and compressor in using the clamp respectively. Then, the inner wall of hose body 1 is smooth, does not have and is the wave type curve, avoids the inner wall unsmooth, to the no disturbance effect of air current flow direction, can reduce the air current resistance, reduces the interference of admitting air, improves the effect of admitting air. The outer wall of the hose body 1 is provided with the arc-shaped bosses 2 and the flat bosses 3, the arc-shaped bosses 2 and the flat bosses 3 are longitudinally arranged in parallel at intervals, and two sides of the flat bosses 3 are connected with the arc-shaped bosses through the connecting rings 4, so that the flexibility of the hose body can be enhanced, the inflation quantity is increased, and the airflow inertia effect is increased.
The radius of the arc-shaped boss 2 is 6-7 mm larger than that of the hose body 1, the radius of the flat boss 3 is 2-3 mm larger than that of the hose body 1, and the radius of the connecting ring 4 is the same as that of the hose body 1, so that airflow resistance can be reduced, air intake interference can be reduced, air intake effect can be improved, inflation quantity can be increased, no disturbance effect on airflow flow direction can be realized, and airflow inertia effect can be increased.
The width of the circular arc boss 2 is 9.5mm-11mm, the width of the flat boss 3 is 7.5mm-10mm, and the width of the connecting ring 4 is 2.5mm-3.5mm, so that the flexibility of the hose body can be enhanced, the inflation quantity can be increased, and the airflow inertia effect can be increased.
The hose body 1, the arc-shaped boss 2, the flat boss 3 and the connecting ring 4 are formed in a one-step vulcanization mode, pressure fluctuation in the air inlet pipe is small, the engine can obtain the best inflation efficiency at different rotating speeds, the engine can be better matched, the inflation quantity is increased, no disturbance effect is caused to the airflow direction, and the airflow inertia effect is increased.
The utility model provides an automobile is with hose that admits air is according to product design data, and numerical control precision finishing forming die, one shot forming vulcanize, the size is accurate, production efficiency is high, can satisfy the requirement that automobile parts articles for use are used for air intake system or exhaust system.
