[0001] The present application relates to the technical field of automobile parts, in particular to the technical field of vehicles, and specifically to a front bumper assembly and a vehicle. Background Art
[0002] In the field of autonomous driving, autonomous driving vehicles need to install autonomous driving marker lights on the front of the vehicle. The autonomous driving marker lights are installed at both ends of the front bumper. When the vehicle turns on assisted driving, the marker lights are used to tell other vehicles on the road that the vehicle is in autonomous driving. At the same time, cars usually add side air ducts on both sides of the front bumper to optimize the air flow field, reduce the car's wind resistance coefficient and increase the mileage of electric vehicles.
[0003] In the related art, the front bumper assembly is usually equipped with side air ducts at both ends of the front bumper near the edges in order to ensure that the side air ducts can cool the brake system. However, this arrangement results in insufficient back space at both ends of the front bumper, and the marker lights can only be installed at the intersection of the side air ducts of the front bumper closer to the middle. At this time, there is a defect that the viewing angle of the marker lights is limited and the marking effect is poor. Summary of the invention

[0018] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.
[0019] like Figure 1 - Figure 4 As shown, the front bumper assembly according to the embodiment of the present application includes a front bumper 1, an air duct 2 and a marker light 3. There are two air ducts 2 and both are installed on the back side of the front bumper 1. An installation space 15 is formed around each air duct 2 and the front bumper 1. Along the length direction of the front bumper 1, the installation space 15 is located on the side of the corresponding air duct 2 away from the other air duct 2. There are two marker lights 3 and they are installed in the two installation spaces 15 respectively.
[0020] According to the front bumper assembly of the embodiment of the present application, two air ducts 2 are installed on the back side of the front bumper 1 to form two side air ducts 25, which can achieve the effect of reducing the wind resistance coefficient of the car and increasing the cruising range. At the same time, an installation space 15 for installing the marker light 3 is reserved on the side of the air duct 2 away from the other air duct 2, that is, the two marker lights 3 are closer to the two ends of the front bumper 1 in the length direction than the two air ducts 2, so that they are easier to be discovered by pedestrians or vehicles located behind the side of the vehicle, have a larger discovery angle, and thus have a better marking effect.
[0021] It should be noted that the two air ducts 2 are arranged in a mirror-symmetrical manner in the length direction of the front bumper 1, that is, the left-right direction and the width direction of the vehicle. The air duct 25 formed by the air duct 2 extends from front to back in a direction gradually approaching the corresponding end edge of the front bumper 1, that is, the two air ducts 25 are distributed in an inverted "eight" shape, so that the air outlet of the air duct 25 is directly facing the brake system at the front wheel to achieve cooling of the brake system.
[0022] In some embodiments of the present application, Figure 1 - Figure 4 As shown, the front bumper 1 includes a first side panel 12, a front panel 11, and a second side panel sequentially connected along the length direction of the front bumper, and the first side panel 12 and the second side panel are bent relative to the front panel 11 toward the back side of the front panel 11. One of the air ducts 2 is surrounded by the first side panel 12 and a part of the front panel 11 to form an installation space 15, and the other air duct 2 is surrounded by the second side panel and a part of the front panel 11 to form an installation space 15.
[0023] Thus, the marker light 3 installed in the installation space 15 can be close to or even closely attached to the first side panel 12 or the second side panel, and thus closer to the two end edges of the front bumper 1, thereby having a wider angle of discovery. Moreover, the U-shaped groove structure with an open back side formed on the front bumper 1 can effectively hide the air duct 2 and the marker light 3, and the installation reliability of the air duct 2 and the marker light 3 on the front bumper 1 is higher.
[0024] Specifically, Figure 1 - Figure 3 As shown, the front bumper 1 includes an upper bumper body 13 and a lower bumper body 14 that are detachably connected, wherein the first side panel 12 , the second side panel and a portion of the front panel 11 constitute the upper bumper body 13 , and the remaining portion of the front panel 11 constitutes the lower bumper body 14 .
[0025] In some embodiments of the present application, the marker light 3 includes a first body and a first flange 34 connected to each other, and the first flange 34 is connected to the front panel 11 through a first screw. The first flange 34 is arranged on a side of the first body away from the corresponding air duct 2, and / or, the first flange 34 is arranged on at least one side of the first body on two opposite sides in the height direction of the front panel 11.
[0026] That is, the first flange 34 is not provided between the first body and the corresponding air duct 2, so that the distance between the first body and the air duct 2 can be designed to be smaller, which effectively saves the back space of the front bumper 1 and can be closer to the end edge of the front bumper 1, thereby further ensuring that the air duct 25 formed by the air duct 2 effectively cools the brake system and ensures that the marker light 3 can be detected at a larger viewing angle.
[0027] Specifically, a first mounting hole is provided on the first flange 34 , the first threaded member is a bolt, and a first threaded hole corresponding to the first flange 34 is provided on the front panel 11 . The bolt passes through the first mounting hole and is threadedly engaged with the first threaded hole.
[0028] In some embodiments of the present application, the air duct 2 includes a second body and a second flange 23 connected to each other, the second body forms an air duct 25, and the second flange 23 is connected to the front panel 11 through a second screw member. The second flange 23 is arranged on a side of the second body away from the corresponding marker light 3, and / or, the second flange 23 is arranged on at least one side of the second body on two opposite sides in the height direction of the front panel 11.
[0029] That is, neither the first flange 34 nor the second flange 23 is provided between the second body and the first body of the air duct 2, and the distance between the two can be designed to be smaller, the marker light 3 and the air duct 2 occupy less space at the back of the front bumper 1, and the structure is more compact.
[0030] Specifically, the second flange 23 is provided with a second mounting hole, the second threaded member is a bolt, the front panel 11 is provided with a second threaded hole corresponding to the second flange 23 one by one, the bolt passes through the second mounting hole and is threadedly matched with the second threaded hole.
[0031] In some embodiments of the present application, Figure 3 As shown, the air duct 2 further includes a third flange 24 connected to the second body, and the third flange 24 and the second flange 23 are respectively located at the first end and the second end of the second body. The third flange 24 in one of the air ducts 2 is connected to the first side plate 12 through a third screw member, and the third flange 24 in the other air duct 2 is connected to the second side plate through a third screw member.
[0032] That is, the front end of the second body is connected to the front panel 11 through the first flange 34, and the rear end of the second body is connected to the first side panel 12 / the second side panel through the second flange 23. As a result, the installation reliability of the air duct 2 on the back side of the front bumper 1 is higher, and the air outlet of the air duct 25 is closer to the end edge of the front bumper 1, so as to better realize the cooling of the brake system.
[0033] Specifically, the third flange 24 can be an annular plate surrounding the second body, with at least two third mounting holes provided on the annular plate, and the third threaded member is a bolt, which passes through the third mounting hole and is threadedly matched with the third threaded hole on the first side plate 12 / the second side plate.
[0034] In some embodiments of the present application, the front panel 11 is provided with a mounting hole communicating with the mounting space 15. The first body includes a front shell 31, a rear shell 32 and a lamp 33, the front shell 31 and the rear shell 32 are connected and surround to form a mounting cavity, the marker lamp 3 is installed in the mounting cavity, at least part of the front shell 31 is fitted in the mounting hole, and the rear shell 32 is connected to the first flange 34.
[0035] The front shell 31 is made of a transparent material, and the light emitted by the lamp 33 is emitted outside the vehicle through the front shell 31 and the mounting hole to serve the purpose of alerting pedestrians. The cooperation between the front shell 31 and the mounting hole realizes the preliminary positioning of the marker light 3 on the front bumper 1, and the connection between the first flange 34 and the front panel 11 further improves the installation reliability of the marker light 3 on the front bumper 1.
[0036] Specifically, the front shell 31 and the rear shell 32 are welded, and a stepped surface is provided on the front shell 31. After at least a portion of the front shell 31 is fitted into the mounting hole, the stepped surface abuts against the back of the front panel 11 to prevent the front shell 31 from further extending out of the front bumper 1. At the same time, the outer surface of the front shell 31 is smoothly connected with the outer surface of the front panel 11, and the outer surface of the front shell 31 extends obliquely rearward from the middle of the front panel 11 toward the end edge, thereby making it easier to be discovered by pedestrians or vehicles on the side of the vehicle.
[0037] In some embodiments of the present application, Figure 4 As shown, an air inlet hole 111 is provided on the front panel 11 , and the inner wall surface of the air inlet hole 111 is connected with the inner wall surface of the air duct 2 .
[0038] The connection between the inner wall surfaces of the two ensures a smooth transition of the shaped surface of the outer surface of the front bumper assembly, further reducing wind resistance while also improving the appearance of the front bumper assembly.
[0039] Specifically, the air inlet hole 111 is a bell-mouth structure, that is, the cross-sectional area of the air inlet hole 111 gradually decreases from the front to the rear of the front panel 11 .
