Protective type air inlet grille assembly and vehicle with same

Technical Field

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

Background

In the running process of the fuel automobile, enough air and fuel are required to be inhaled for mixed combustion to generate power so as to drive the automobile to run. Meanwhile, in order to prevent the damage caused by the entry of foreign large objects such as stones into the engine compartment, an air inlet grille design is required at the front end of the air inlet, and the required air for combustion needs to enter between grille sheets or grille nets with enough space, and the large-size foreign objects are required to be physically isolated. In addition to ensuring the basic driving requirements of the vehicle on the road surface, the protective vehicle, such as a bullet proof vehicle, needs to have mobility in the first time of being subjected to bullet attack, has the capability of being separated from dangerous areas and the like, and the front grille area which is in direct air communication with the outside is a weak protection area of the engine compartment area.

In the prior art, foreign matters entering an engine room can be greatly reduced by increasing the inclination angle of the grid plates and forming a certain overlapping length, so that the maneuverability of the vehicle body is ensured. However, the large angle of inclination and overlap length drastically reduces the flow of air through the grille into the engine compartment during vehicle travel, particularly at high speeds. In addition, from the viewpoint of light weight of the vehicle body, the overlapping length between the grid plates 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), boundary effect occurs in the edge area, and bullet refraction and bullet jump occur in the rest area, so that the steel grid plate enters the engine compartment. There is a risk of failure of the protection.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, a protective type air intake grille assembly and a vehicle having the same according to the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention.

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

Referring to fig. 1 to 4, the protective air intake grille assembly provided by the embodiment of the invention includes a mounting bracket 10, a plurality of grille pieces 20 arranged on the mounting bracket 10 in parallel at intervals, and a plurality of reinforcing blocks 30 vertically connected with the grille pieces 20 and the mounting bracket 10.

The mounting bracket 10 includes a main body frame 11 having an opening in the middle, and two side plates 12 connected to both sides of the main body frame 11 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 obliquely provided with a plurality of installation chute 13.

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

The angle of the installation chute 13 relative to the end surface 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 remote from the main body frame 11 is 59 degrees.

Each grid 20 comprises a long grid 22 and a short grid 21 connected at an acute angle to the top of the long grid 22. Such that short grid segments 21 form V-shaped angles with long grid segments 22.

In the present embodiment, the long grating 22 has an arc-shaped cross-section, the short grating 21 extends upward and outward from the long grating 22, and the angle of the V-shaped angle formed between the short grating 21 and the tangential direction of the long grating 22 is 40 to 50 degrees, preferably 46 degrees.

The outer sides of the two ends of the long grid piece 22 along the length are also provided with mounting lugs 23 in a protruding mode, and the mounting lugs 23 on the two sides respectively extend into the opposite mounting chute 13 of the two side plates 12, so that the grid piece 20 is mounted.

The long grid 22 forms a first angle with the top surface (i.e., horizontal plane) of the side plate 12, the short grid 21 forms a second angle with the top surface of the side plate 12, and the first angle and the second angle are acute angles.

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

Preferably, the end of the long grating 22 far from the short grating 21 is also provided with a plurality of clamping grooves, and the inner side of the reinforcing block 30 far from the main body frame 11 is clamped into the clamping grooves of the long grating 22. Positioning and limiting of the grid plate 20 are achieved. The reinforcing blocks 30 are used for reinforcing the mounting reliability of the grid plates 20, avoiding bending deformation of the grid plates 20 under the action of wind force and improving the rigidity of the grid plates.

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

Referring to fig. 5, in use, external air enters between the short grating pieces 21 of the lower grating piece 20 and the long grating pieces 22 of the upper grating piece 20, so that a horn-shaped air inlet with gradually reduced width is formed from outside to inside, a large amount of air can be received, and in the air entering process, as the width of the channel is gradually reduced, a small hole throttling effect is formed, so that the pressurizing, accelerating and cooling treatment of the air is realized, and the cooling effect is improved.

After the high-speed gas enters the engine cabin, part of the high-speed gas is mixed with fuel oil through equipment such as an air inlet of the engine, an air filter and the like, and enters a combustion chamber for combustion to generate power for supporting the motor running of the vehicle; the other part of gas circulates in the engine room, and the high-speed low-temperature gas can take away the surface heat of parts with higher temperature such as a water tank, thereby improving the cooling effect. Meanwhile, as the grid plates 20 adopt a V-shaped structure, structural overlapping is formed between the short grid plates 21 and the long grid plates 22 of the adjacent grid plates 20, so that the gap amount is ensured, and the protection failure caused by boundary effect is reduced; external objects, such as pellets, can change the flight direction after colliding with the grid plate, and even bounce off. The outermost protective coating has the characteristics of high toughness and high elasticity, and can keep low-speed pellets and fragments in the protective coating, so that the risk of protective failure caused by 'jumping' is reduced, and the area range of secondary damage around a vehicle is also reduced.

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

In an embodiment of the present invention, a vehicle is further provided, which has the protective type air intake grille assembly.

The vehicle according to the embodiment of the invention comprises the protective type air inlet grille assembly according to the embodiment of the invention, and the protective type air inlet grille assembly according to the embodiment of the invention has the technical effects, so that the vehicle according to the embodiment of the invention also has the corresponding technical effects of increasing the air inflow of an engine compartment, forming a small hole throttling effect, performing pressurization, acceleration and cooling treatment when air enters, improving the cooling effect, and simultaneously effectively avoiding protective failure caused by bouncing of external objects between grille sheets.
