Description

Protection type air-inlet grille subassembly and vehicle that has it

Technical Field

The invention relates to the field of vehicles, in particular to a protective air inlet grille assembly and a vehicle with the same.

Background

In the process of driving the fuel-oil automobile, enough air needs to be sucked and mixed with fuel oil to generate power so as to drive the automobile to run. Meanwhile, in order to prevent the damage caused by the fact that external large objects such as stones enter the engine compartment, the air inlet grille needs to be designed at the front end of the air inlet, enough space needs to be reserved between the grille plates or the grille nets for the required air for combustion to enter, and the large-size external objects need to be physically isolated. Protective vehicles, such as bulletproof vehicles, need to have mobility in the first time of being subjected to bullet attacks and have the capability of being separated from dangerous areas and the like, besides the basic driving requirement of the vehicles on the road surface is ensured, and a front grille area which is directly communicated with the outside air is a weak protective area of an engine compartment area.

In the prior art, foreign objects can be greatly reduced to enter an engine compartment by increasing the inclination angle of the grid pieces and forming a certain overlapping length, and the maneuverability of a vehicle body is ensured. However, with large tilt angles and overlap lengths, the flow of air through the grille into the engine compartment is drastically reduced during vehicle operation, particularly at high speeds. In addition, from the perspective of light weight of the vehicle body, the overlapping length between the grating sheets is too long, so that the weight is heavy; in addition, when the steel grid plate is subjected to high-speed impact (such as bullet impact), a boundary effect occurs in an edge area, and a shot refraction and bounce occurs in the rest area, so that the steel grid plate enters an engine compartment. There is a risk of failure of the protection.

It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

The following first describes in detail a protective type intake grill assembly and a vehicle having the same provided according to an embodiment of the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 4, the protective air intake grill assembly according to the embodiment of the present invention includes a mounting bracket 10, a plurality of grill plates 20 disposed on the mounting bracket 10 in parallel and at intervals, and a plurality of reinforcing blocks 30 vertically connected to the grill plates 20 and the mounting bracket 10.

The mounting bracket 10 includes a main body frame 11 having an opening at a middle portion thereof, and two side plates 12 connected to both sides of the main body frame 11, respectively, and extending toward the same side of the main body frame 11.

The end surfaces of the two side plates 12 far away from the main body frame 11 are both obliquely provided with a plurality of installation inclined grooves 13.

In the present embodiment, the main body frame 11 is rectangular, the opening in the middle thereof is also rectangular, and four corners of the opening are rounded.

The angle of the installation chute 13 relative to the end face of the side plate 12 far away from the main body frame 11 is 50-60 degrees; preferably, the angle of the mounting chute 13 with respect to the end surface of the side plate 12 away from the main body frame 11 is 59 degrees.

Each grating sheet 20 comprises a long grating sheet 22 and a short grating sheet 21 connected with the top end of the long grating sheet 22 at an acute angle. So that a V-shaped angle is formed between the short grating pieces 21 and the long grating pieces 22.

In the present embodiment, the long grating pieces 22 have an arc-shaped cross section, the short grating pieces 21 extend toward the upper outer side of the long grating pieces 22, and the angle of the V-shaped included angle formed between the short grating pieces 21 and the tangential direction of the long grating pieces 22 is 40 to 50 degrees, preferably 46 degrees.

The long grating pieces 22 are further provided with mounting projections 23 protruding from the outer sides of the two ends along the length, and the mounting projections 23 on the two sides respectively extend into the mounting chutes 13 opposite to the two side plates 12, so that the grating pieces 20 are mounted.

A first included angle is formed between the long grating pieces 22 and the top surface (i.e. horizontal surface) of the side plate 12, a second included angle is formed between the short grating pieces 21 and the top surface of the side plate 12, and the first included angle and the second included angle are acute angles.

The plurality of reinforcing blocks 30 are parallel to and spaced at the opening of the main body frame 11, and the outer sides of the upper and lower ends of the reinforcing blocks 30 are fixedly connected with the main body frame 11, such as welded. The middle part of the reinforcing block 30 is connected with the end of the long grating piece 22 far away from the short grating piece 21 at the inner side far away from the main body frame 11.

Preferably, a plurality of slots are further formed in one end of the long grating piece 22 away from the short grating piece 21, and the inner side of the reinforcing block 30 away from the main body frame 11 is clamped into the slots of the long grating piece 22. The positioning and limiting of the grid sheet 20 are realized. The reinforcing block 30 is used to enhance the installation reliability of the grid segments 20, prevent the grid segments 20 from bending and deforming under the action of wind, and improve the rigidity thereof.

The outer surfaces of the mounting bracket 10, the grid sheet 20 and the reinforcing block 30 are all coated with high-toughness and high-elasticity protective coating.

Referring to fig. 5, when in use, external air enters from between the short grid pieces 21 of the grid pieces 20 below and the long grid pieces 22 of the grid pieces 20 above, so that a trumpet-shaped air inlet with gradually decreasing width from outside to inside is formed, a large amount of air can be received, and in the process of entering the air, due to the gradually decreasing width of the channel, a small hole throttling effect is formed, so that the air is pressurized and cooled quickly, and the cooling effect is improved.

After the high-speed gas enters an engine compartment, a part of the high-speed gas is mixed with fuel oil through equipment such as an air inlet and an air filter of the engine and the like and enters a combustion chamber for combustion to generate power for supporting the motor-driven running of the vehicle; the other part of gas circulates in the engine compartment, and the high-speed low-temperature gas can take away the surface heat of parts with higher temperature, such as a water tank, and the like, so that the cooling effect is improved. Meanwhile, as the grating pieces 20 adopt a V-shaped structure, the short grating pieces 21 and the long grating pieces 22 of the adjacent grating pieces 20 form structural overlapping, the gap amount is ensured, and the protection failure caused by the boundary effect is reduced; foreign objects, such as projectiles, may change flight direction after colliding with the grid plate, and even may be ejected. The protective coating on the outermost side has the characteristics of high toughness and high elasticity, and can retain low-speed shots and fragments in the protective coating, so that the protective failure risk caused by 'bounce' is reduced, and the area range of secondary damage around a vehicle can be reduced.

The protective air inlet grille component can increase the air inflow of an engine compartment, form a small hole throttling effect and perform pressurization and accelerated cooling treatment when air enters when a vehicle runs at a high speed, improves the cooling effect and can effectively avoid the protection failure caused by the bouncing of external objects between grille pieces.
