Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a front bumper guide structure and a vehicle. Background Art

[0002] With the development of vehicle technology, saving energy and increasing unit mileage have always been the direction of continuous exploration and efforts of the vehicle industry. Air resistance accounts for the main component of the vehicle's driving resistance. Reducing wind resistance can greatly save energy and increase unit mileage. When the vehicle is driving, the airflow in front of the vehicle will flow to four directions after contacting the vehicle surface, namely the roof, the bottom of the vehicle and the sides. The distribution and attachment of the airflow in the four directions have a significant impact on the wind resistance of the vehicle. Among them, the front bumper of the vehicle is located on the front windward side of the vehicle, which has a great impact on the wind resistance of the vehicle during driving.

[0003] In order to reduce the wind resistance of the vehicle while driving and highlight the momentum and personality, many stylists like to make exaggerated shapes at the corners of the front bumper of the vehicle, that is, at the front fog lamp. However, this shape will cause very serious airflow separation, greatly increasing wind resistance. For this reason, in the prior art, air curtains are opened here to produce pressure relief and diversion effects. However, the drag reduction effect of air curtains is not obvious, and is far from enough to offset the impact of the shape on wind resistance.

[0004] Therefore, a new solution is needed to solve the above problems. Utility Model Content

[0031] like Figures 1 to 4 As shown, some embodiments of the present application provide a front bumper air guide structure, including a front bumper body 1 and a first air guide plate 2 and a second air guide plate 3 installed on the front bumper body 1. Among them, an air inlet 11 is provided on the front bumper body 1. The first air guide plate 2 and the second air guide plate 3 are connected to form a first air guide tube 4 for gas circulation, and the first air guide tube 4 is set to a structure with four sides closed and two ends open, and the air inlet end of the first air guide tube 4 is connected to the above-mentioned air inlet 11, and the air outlet end of the first air guide tube 4 is connected to the outside. The airflow flowing in from the air inlet 11 is guided through the first air guide tube 4 and discharged from the air outlet end of the first air guide tube 4 to the outside of the vehicle body, thereby reducing the frontal wind pressure of the front bumper, which is conducive to reducing the wind resistance during the driving process of the vehicle. In addition, the first air guide tube 4 is provided with a primary pressure reducing portion 41 and a secondary pressure reducing portion 42 inside to reduce the airflow entering the first air guide tube 4 twice, which is conducive to reducing the wind noise inside the first air guide tube 4, thereby improving the perceived quality of the user during the driving process.

[0032] Specifically, the air inlet 11 is located on both sides of the width direction of the vehicle body, which is conducive to introducing the airflow in the high-pressure area on both sides of the front bumper into the first air guide 4, thereby reducing the frontal wind pressure of the front bumper. The outlet end of the first air guide 4 is arranged near the outside of the vehicle body, preferably near the outside of the tire, so that the airflow is guided to the outside of the tire, avoiding the airflow hitting the tire due to the outlet end of the first air guide 4 being close to the tire.

[0033] Exemplarily, the first air guide plate 2 and the second air guide plate 3 can be connected by a snap-fit, and the first air guide tube 4 formed by the first air guide plate 2 and the second air guide plate 3 is a flat channel, which is beneficial to reduce the space occupied by the first air guide plate 2 and the second air guide plate 3, and thus is beneficial to install the first air guide plate 2 and the second air guide plate 3 without changing other structures of the vehicle body.

[0034] Exemplarily, the first air deflector 2 and the second air deflector 3 may be mounted on the front bumper body 1 by welding, screwing, snapping, or the like.

[0035] In some embodiments, a second air duct 6 is also provided between the air inlet 11 and the first air duct 4, the air inlet end of the second air duct 6 is installed at the air inlet 11 of the front bumper body 1, and the air outlet end of the second air duct 6 is connected to the air inlet end of the first air duct 4, that is, the air inlet 11 and the first air duct 4 are connected through the second air duct 6.

[0036] Specifically, the second air guide tube 6 can be set as a cylindrical structure, the width of which gradually decreases in the direction toward the first air guide tube 4, that is, the width of the air inlet end of the second air guide tube 6 is greater than the width of the air outlet end. Such a setting is conducive to allowing more oncoming wind of the front bumper to enter the second air guide tube 6, so as to reduce the frontal wind pressure of the front bumper.

[0037] It should be noted that the width direction of the cylindrical structure of the second air guide tube 6 is consistent with the width direction of the vehicle body.

[0038] Exemplarily, the second air guide tube 6 can be connected to the front bumper body 1, the first air guide plate 2 and the second air guide plate 3 by welding, screwing, snapping, etc. The provision of the second air guide tube 6 is beneficial to improving the stability of the structure at the air inlet 11 of the front bumper body 1, and is beneficial to avoiding deformation of the air inlet 11 under the action of headwind during driving of the vehicle, thereby reducing the processing cost of the air inlet 11.

[0039] For example, in order to further increase the amount of air entering the second air guide tube 6 and further reduce the frontal wind pressure of the front bumper, a guide slope 12 is provided on the front bumper body 1, and the guide slope 12 is connected to the air inlet 11. The oncoming wind that contacts the front bumper body 1 enters the air inlet 11 under the guiding action of the guide slope 12, that is, enters the second air guide tube 6.

[0040] In some embodiments, a filter screen 5 is installed at the air outlet end of the second air duct 6 , and the filter screen 5 completely blocks the air outlet end of the second air duct 6 , which helps to prevent foreign matter from entering the first air duct 4 .

[0041] Exemplary, the filter screen 5 is provided between the first air guide 4 and the second air guide 6, which is conducive to the installation of the filter screen 5 and also to ensure the stability of the structure of the filter screen 5 during the vehicle's driving process.

[0042] For example, the filter screen 5 can be configured to be composed of diamond-shaped holes 52 formed by ribs 51, and the diamond-shaped holes 52 are arranged in an orderly manner. The ratio of the width of the ribs 51 to the width of the diamond-shaped holes 52 is set to 1:5, so as to prevent stones and other debris from entering the first air guide tube 4 to the greatest extent.

[0043] In some embodiments, the first-stage decompression unit 41 is disposed at the air inlet end of the first air duct 4 to perform a first decompression on the airflow entering the first air duct 4 from the air inlet end. The second-stage decompression unit 42 is disposed in the middle of the first air duct 4 to perform a second decompression on the airflow flowing through the middle of the first air duct 4, which is beneficial to reducing the generation of wind noise, and further beneficial to improving the perceived quality of the user during the driving process.

[0044] Specifically, the width of the air inlet end of the first air guide 4 is greater than the width of the air outlet end of the second air guide 6, so that the air inlet end of the first air guide 4 forms a primary pressure relief portion 41, and the airflow entering the first air guide 4 is first pressure-reduced. The width of the middle part of the first air guide 4 is greater than the width of the air inlet end of the first air guide 4, so that the middle part of the first air guide 4 forms a secondary pressure relief portion 42, and the airflow entering the first air guide 4 is secondarily pressure-reduced. Through the above two pressure reliefs, the wind noise generated by the airflow in the first air guide 4 is reduced.

[0045] It should be noted that the widths of the first air guide 4 and the second air guide 6 are consistent with the width of the vehicle body.

[0046] Exemplarily, the area where the first air guide plate 2 is located in the first air guide tube 4 is set to a sloped structure, and the area where the second air guide plate 3 is located in the first air guide tube 4 is set to a curved structure, so that the interior of the first air guide tube 4 has a streamlined structure to facilitate the circulation of air.

[0047] It should be noted that the first air guide plate 2 is provided with a first air outlet surface 21, and the second air guide plate 3 is provided with a second air outlet surface 31, and the first air outlet surface 21 and the second air outlet surface 31 form the air outlet end of the first air guide tube 4. According to different vehicle structure, at the beginning of the design, the angle of the first air outlet surface 21 and the second air outlet surface 31 relative to the first air guide tube 4 is adjusted to control the flow direction of the airflow after it flows out from the air outlet end of the first air guide tube 4.

[0048] Exemplarily, the width of the outlet end of the first air duct 4 toward the second air duct 6 is smaller than the width of the middle of the first air duct 4 , so as to pressurize the airflow about to flow out of the first air duct 4 , which is conducive to the airflow flowing out of the first air duct 4 .

[0049] In this embodiment, when the vehicle is driving, the oncoming wind of the front bumper enters the air inlet 11 under the guiding action of the guiding slope 12, and then enters the second air duct 6. The airflow entering the second air duct 6 then enters the first air duct 4, and undergoes secondary decompression through the primary decompression part 41 and the secondary decompression part 42 of the first air duct 4, and is finally guided out from the air outlet end of the first air duct 4 to the outside of the tire; and the first air duct is provided with a primary decompression part and a secondary decompression part to decompress the airflow entering the first air duct twice, which is beneficial to reducing the wind noise inside the first air duct and improving the perceived quality of the user.

[0050] Some embodiments of the present application also provide a vehicle that includes the front bumper flow guide structure described above.

[0051] To sum up, the utility model provides a front bumper air guide structure and a vehicle, by arranging a first air guide plate and a second air guide plate on the front bumper body, so that the first air guide plate and the second air guide plate form a first air guide tube, and the first air guide tube is connected to the air inlet on the front bumper to guide the airflow entering through the air inlet, so as to guide the airflow from the air outlet end of the first air guide tube to the outside of the vehicle body, thereby reducing the frontal wind pressure of the front bumper, which is beneficial to reducing the wind resistance of the vehicle during driving.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
