Description

Air inlet grille of vehicle cabin

Technical Field

The utility model relates to a vehicle accessory especially relates to a vehicle cabin air-inlet grille.

Background

The air inlet grille of the vehicle in the prior art has the functions of preventing flying insects, stones and the like from entering the engine room in the driving process of the vehicle, thereby protecting the water tank and each component in the engine room from being impacted by foreign objects, and simultaneously providing effective heat dissipation for the work of power components through air inlet to cool the engine; in addition, the utility model can also play a decorative role.

When the vehicle goes under abominable operating mode (like long distance climbing etc.), especially electronic bus, the motor generates heat seriously, has higher requirement to the intake, and prior art's air intake grille's the angle of setting up is mostly 45 and is bigger even, and its intake can not satisfy the cooling requirement of motor cooling circuit when electronic bus goes under abominable operating mode, need to promote motor cooling module's intake through effective measure urgently, otherwise can very big influence the normal operating and the life of motor.

In addition, the grid pieces arranged at an angle of 45 degrees or more result in a larger area of the cabin exposed outside, which is not beneficial to protecting parts in the cabin. .

Disclosure of Invention

An object of the utility model is to provide a vehicle cabin air-inlet grille can improve the intake to the air inlet demand of motor cooling circuit when satisfying the vehicle and go under abominable operating mode.

The utility model discloses a realize like this:

a vehicle cabin air inlet grille comprises a grille body, a plurality of ventilation openings and a plurality of grille pieces; the plurality of ventilation openings are arranged on the grating body at intervals, and the plurality of grating pieces are embedded in the grating body in parallel and are correspondingly arranged on the plurality of ventilation openings to form an air inlet grating structure;

the middle part of the grating sheet is bent inwards to form a folded angle structure, one side of the folded angle of the grating sheet is fixed on the grating body, the other side of the folded angle of the grating sheet is obliquely covered on the ventilation opening, and the included angle between the grating sheet and the grating body, namely the grating angle a, ranges from 30 degrees to 36 degrees.

The grid angle a is 33 degrees.

The grating pieces and the grating body are of an integrated structure.

The number of the ventilation openings and the number of the grating pieces are 8.

The length of the grid plate does not exceed the length of the ventilation opening.

Compared with the prior art, the utility model, following beneficial effect has:

1. the utility model discloses optimize the grid angle to 30-36 for the grid intake has certain promotion, and reaches the intake when the grid angle is 33 and is optimal, satisfies vehicles such as electronic big bus to the demand of admitting air.

2. The utility model discloses optimize the grid angle to 30-36 for the cabin exposes in external area littleer, and the grid piece is inside concave dog-ear structure, and is stronger to the guard action of spare part in the cabin, and the decorative effect that the grid possessed also has certain promotion.

3. The utility model discloses simple structure, low in manufacturing cost suits to use on each motorcycle type.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 and 2, an air intake grille for a vehicle cabin comprises a grille body 1, a plurality of ventilation openings 2 and a plurality of grille pieces 3; a plurality of ventilation openings 2 are arranged on the grating body 1 at intervals, and a plurality of grating sheets 3 are embedded in the grating body 1 in parallel and are correspondingly arranged on the ventilation openings 2 to form an air inlet grating structure.

Referring to fig. 3 and 4, the middle of the grating sheet 3 is bent inward to form a folded angle structure, such that one side of the folded angle of the grating sheet 3 is fixed on the grating body 1, the other side of the folded angle of the grating sheet 3 covers the ventilation opening 2 in an inclined manner, and an included angle between the other side of the folded angle of the grating sheet 3 and the grating body 1, i.e., a grating angle a, ranges from 30 ° to 36 °. Preferably, the angle a of the grille is 33 degrees calculated by a Computational Fluid Dynamics (CFD) simulation technology, so that the air intake amount is optimized, the air intake requirement of the motor cooling circuit is met, and the exposed area of the cabin is reduced.

The grating pieces 3 and the grating body 1 are of an integral structure, and are high in strength and stable in structure.

The number of the ventilation openings 2 and the number of the grating pieces 3 are 8, so that the air inflow is ensured, and the air inflow requirement of a motor cooling loop of a vehicle such as a bus is met.

The length of the grid pieces 3 does not exceed that of the ventilation openings 2, and preferably, the ventilation openings 2 can be slightly longer than the grid pieces 3, so that the air inflow can be further improved.
