Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Several embodiments of the invention are given in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example one

Referring to fig. 1 to 3, a front bumper according to a first embodiment of the present invention includes a main body 10, a grille 20 disposed on the main body 10, and a plurality of air deflectors 30 disposed on a back surface of the main body 10, wherein:

the width of the two ends of the grating 20 in the length direction is gradually reduced to form a sharp corner 21 at each end of the grating 20 in the length direction, and the sharp corner 21 is arranged to provide the grating 20 with better aesthetic appearance. The wind deflector 30 is arranged at the sharp corner 21 at the two ends of the grille 20, the wind deflector 30 is enclosed behind the sharp corner 21, and the wind deflector 30 extends towards the rear of the central part of the grille 20 in an inclined way so as to guide the wind entering from the sharp corner 21 to the rear of the central part of the grille 20, thereby guiding the wind to the cooling system positioned at the rear of the central part of the grille 20.

Specifically, in the present embodiment, the grille 20 includes an upper grille 20a and a lower grille 20b, that is, the front bumper in the present embodiment includes two grills 20, one is an upper grille 20a disposed on the top of the body 10, and the other is a lower grille 20b disposed in the middle of the body 10 and located right below the upper grille 20a, centers of the upper grille 20a and the lower grille 20b are located on the same straight line, two ends of the upper grille 20a and the lower grille 20b form a sharp corner 21, and a wind deflector 30 is disposed at the sharp corner 21 of each of the two ends of the upper grille 20a and the lower grille 20 b.

The length of the lower grid 20b is greater than that of the upper grid 20a, and the length of the air deflector 30 at the sharp corner 21 of the lower grid 20b is greater than that of the air deflector 30 at the sharp corner 21 of the upper grid 20 a. Because the lower grid 20b is longer, the sharp corners 21 at the two ends of the lower grid 20b are further away from the rear of the central part of the grid 20, and therefore the length of the air deflector 30 at the sharp corners 21 of the lower grid 20b can be correspondingly longer, so that more wind entering the two ends of the lower grid 20b can be guided to the rear of the central part of the grid 20.

However, the length of the air deflector 30 is not too long, and the length of the air deflector 30 is too long, so that although the air can be guided to the cooling system located behind the central portion of the grille 20, the area of the cooling system that can blow the air is reduced, and the appearance of the grille 20 is also affected; the length of the air guiding plate 30 is also too short, and the air quantity guided to the cooling system is too small due to the too short length of the air guiding plate 30, so that the air guiding plate 30 cannot play the maximum role. Therefore, it is preferable that the projection of the end of the wind deflector 30 on the cooling system is close to or coincident with the edge of the cooling system (as shown in fig. 4), so that the wind deflector 30 can increase the wind guiding amount without shielding the wind receiving surface of the cooling system. In order to achieve the preferable state, in the embodiment, the projection of the air deflector 30 at the sharp corner 21 of the upper grid 20a on the upper grid 20a covers half of the sharp corner 21 of the upper grid 20a, and the projection of the air deflector 30 at the sharp corner 21 of the lower grid 20b on the lower grid 20b covers the whole sharp corner 21 of the lower grid 20b, so that the projection of the tail end of the air deflector 30 on the cooling system can be close to or coincident with the edge of the cooling system, and the air receiving capacity of the cooling system can be improved under the condition that the air receiving area of the cooling system is not influenced.

Specifically, the air deflector 30 includes a wind blocking portion 31 and two connecting portions 32 extending outward from two sides of the wind blocking portion 31, one end of the wind blocking portion 31 is connected to an end point of the sharp corner 21, the other end of the wind blocking portion extends obliquely toward the rear of the central portion of the grille 20, and the two connecting portions 32 are respectively connected to two side edges of the sharp corner 21, so that the air deflector 30 is enclosed behind the sharp corner 21, and the air entering from the sharp corner 21 can only be blown out from a space enclosed by the air deflector 30 and the main body 10, and then blown toward the cooling system.

In specific implementation, since the front bumper is generally made of plastic, the air deflector 30 and the body 10 are preferably integrally injection-molded, so that the air deflector 30 and the body 10 belong to one component instead of two independent components, thereby reducing the manufacturing cost and the assembly cost and improving the assembly efficiency.

To sum up, the front bumper in the above embodiment of the present invention sets the air deflector 30 at the sharp corner 21 at both ends of the grille 20, and makes the air deflector 30 enclose and block the rear of the sharp corner 21 and the orientation the rear of the central portion of the grille 20 extends in an inclined manner, so that the air entering from the sharp corner 21 will be guided by the air deflector 30 to the cooling system located at the rear of the central portion of the grille 20, and the air entering from the grille 20 is blown to the cooling system as much as possible, thereby improving the air cooling effect of the cooling system.

Example two

A second embodiment of the present invention provides an automobile, comprising an automobile body and a front bumper disposed on the automobile body, wherein the front bumper is a front bumper in any one of the above embodiments.

In summary, in the automobile of the present embodiment, the wind deflector 30 is disposed at the acute angle 21 at the two ends of the grille 20, and the wind deflector 30 is enclosed behind the acute angle 21 and extends obliquely toward the rear of the central portion of the grille 20, so that the wind entering from the acute angle 21 is guided by the wind deflector 30 to the cooling system located behind the central portion of the grille 20, and the wind entering from the grille 20 is blown to the cooling system as much as possible, thereby improving the wind cooling effect of the cooling system.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
