Abstract
The utility model discloses an automobile air guide opening, including the installation skeleton, swing joint has the blade in the installation skeleton, and the air outlet department that the blade corresponds on the installation skeleton is equipped with the sound absorbing cover, and the sound absorbing cover leans out the installation face formation contained angle that sets up and install the skeleton. When the air outlet, the sound absorbing cover arranged obliquely can guide the air flow to the direction far away from the blades, so that the return air colliding with the blades is avoided, the purpose of further reducing noise is achieved, and the blades can be protected.
Description
Technical Field
The utility model relates to an automobile parts field, concretely relates to automobile air guide port.
Background
The automobile air guide opening is an important part used for exchanging air inside and outside an automobile, when the automobile runs at a high speed, the air noise generated by impact of outside air flow is large, the influence on the comfort is large, an independent closed space is formed inside the automobile to reduce the noise, when the air guide opening is opened, the external space is communicated with the inside, the air flow impacts the air guide opening when passing through the air guide opening, the noise is large, the influence on the interior of the automobile is large, and the overall comfort in the automobile is influenced.
In the existing scheme, a sound absorbing cover is arranged at an air guide opening to eliminate noise, but the sound absorbing cover in the traditional scheme is vertical to the air outlet direction, and airflow returns to the blade to form secondary impact during air outlet, so that the air flow rattling sound is enhanced, and the noise reduction function is weakened.
Disclosure of Invention
The utility model discloses a purpose is perpendicular with the air-out direction to present sound absorbing cover, and the problem that forms the secondary striking on the blade can be got back to the air current during the air-out provides an automobile wind gap.
In order to achieve the purpose of the invention, the utility model provides the following technical scheme:
the utility model provides an automobile air guide opening, includes the installation skeleton, and swing joint has the blade in the installation skeleton, and the air outlet department that the blade corresponds on the installation skeleton is equipped with the sound absorbing cover, and the sound absorbing cover leans out the setting to form the contained angle of settlement angle with the installation face of installation skeleton.
When air needs to be discharged from the interior of the vehicle, air flow in the vehicle blows to open the blades, and the air flow passes through the air opening and impacts on the sound-absorbing cover. The sound absorbing cover is arranged obliquely outwards, the included angle between the sound absorbing cover and the installation surface of the installation framework is 30 degrees, and the sound absorbing cover guides air flow to the direction far away from the blades, so that the return air colliding with the blades is avoided.
Furthermore, the inner wall of the sound absorption cover is provided with sound absorption cotton.
When the air current comes out the striking from the blade and is being inhaled the sound cover on, the striking can play the cushioning effect on inhaling the sound cotton, and then through inhaling the cotton noise reduction of sound.
Further, the mounting framework and the sound absorption cover are integrally formed.
The sound absorption cover and the mounting surface of the mounting framework are at a fixed angle, assembly is not needed in an assembling mode, mold cost can be reduced during production, and the air guide opening is more convenient to mount.
Furthermore, a sealing ring surrounding the periphery of the mounting plane is arranged on the mounting framework.
The air guide opening is installed on an automobile and needs good sealing performance, and the air guide opening is installed through the sealing ring, so that when the automobile conducts air guide, air flow cannot escape outwards through a gap formed in the installation of the air guide opening during ventilation, and air leakage and unnecessary noise are avoided.
Furthermore, a plurality of criss-cross reinforcing ribs are arranged on the rear side of the mounting framework, and a plurality of ventilation openings are formed among the plurality of reinforcing ribs.
Further, the blade is composed of a first blade and a second blade which are arranged in parallel.
Be equipped with the multichannel strengthening rib on the installation skeleton, strengthening rib vertically and horizontally staggered plays the effect of strengthening installation skeleton intensity, forms the vent of upper and lower two-layer railing form simultaneously. The first blade and the second blade are respectively arranged on the upper layer air opening and the lower layer ventilation opening.
Furthermore, the mounting framework is provided with mounting holes.
The mounting hole is used for mounting a fastener for fixing the air guide opening setting bolt.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the sound absorbing cover leans out the setting to personally submit the contained angle with the installation of installation skeleton and be the direction slope that 30, during the air-out, the sound absorbing cover with the air current to the direction guide of keeping away from the blade, thereby avoid forming the return air with the blade striking, reach the purpose of further making an uproar, can protect the blade simultaneously.
2. The mounting framework and the sound absorption cover are integrally formed through injection molding, so that the manufacturing cost is reduced, the structural rigidity can be improved, and the effective noise reduction is ensured.

Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter is limited to the following embodiments, and all the technologies realized based on the present invention are within the scope of the present invention.
An automobile air guide opening is shown in figure 1 and comprises an installation framework 1, a sound absorption cover 2, sound absorption cotton 3, a sealing ring 4, a first blade 5 and a second blade 6.
The sound absorbing cover 2 is arranged obliquely outward relative to the mounting plane 9 of the mounting framework 1, as shown in fig. 2, an included angle is formed between the sound absorbing cover 2 and the mounting framework 1, and the degree of the included angle is 30 degrees.
The mounting framework 1 is provided with a sealing ring 4 surrounding the periphery of the mounting plane 9.
When the mounting framework 1 and the sound absorption cover 2 are formed, the mounting framework 1 and the sound absorption cover are integrally formed by a mold, and the sealing ring 4 and the mounting framework 1 are subjected to double-color injection molding.
