Description

Technical Field

[0001] The utility model belongs to the technical field related to vehicle front bumpers, in particular to a front bumper and a vehicle. Background Art

[0002] With the development of automotive technology, energy conservation and increased mileage have been the focus of continuous exploration and effort in the automotive industry. Reducing wind resistance can significantly save energy and increase mileage. Existing vehicles often utilize a side curtain airbag deflector structure on the front bumper. By installing side curtain airbags on the front bumper, high-pressure airflow is directed through the side curtain airbags to the openings in the front wheel arches and ultimately out of the vehicle during driving, effectively reducing the vehicle's drag coefficient.

[0003] At present, the side air curtains in the front bumper of a vehicle are usually welded and fixed to the front upper body of the front bumper, and an air outlet on the side air curtain is used to guide the airflow to the opening of the front wheel cover. Considering that the opening at the edge of the front wheel cover cannot be too large, it will directly affect the matching gap of the surrounding parts of the front wheel cover and the exquisite appearance of the entire vehicle. Therefore, the high-pressure airflow in front of the vehicle cannot be quickly guided out of the vehicle, and the drag coefficient needs to be optimized. Utility Model Content

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or at least two of the associated listed items.

[0038] like Figures 1 to 4As shown, the front bumper 100 provided in the present application includes a front bumper body 10 and side air curtains 20. The front bumper body 10 includes a front bumper upper body 11 and a front bumper lower body 12, with the front bumper lower body 12 connected to the front bumper upper body 11. The side air curtains 20 are connected to the front bumper body 10 and have an air inlet 21, a first air outlet 22, and a second air outlet 23. The air inlet 21 and the first air outlet 22 are located at the location of the front bumper upper body 11, and the second air outlet 23 is located at the location of the front bumper lower body 12. The first air outlet 22 and the second air outlet 23 are respectively connected to the air inlet 21 to guide the air introduced into the side air curtains 20 through the air inlet 21 to the opening of the front wheel housing (not shown). In other words, the side air curtains 20 in the front bumper 100 can add the second air outlet 23 in addition to the original first air outlet 22 for air discharge. In the present application, the side air curtain 20 guides air toward the opening of the front wheel arch by using the first air outlet 22 and the second air outlet 23. In this way, the air outlet area used to guide air when the side air curtain 20 is assembled on the front bumper body 10 can be expanded. In this way, the air passing through the side air curtain 20 can be effectively diluted and guided, avoiding the air vortex generated by excessive flow rate, thereby reducing the wind resistance encountered by the vehicle using the front bumper 100 during driving.

[0039] like Figure 3 As shown, a connection portion 110 is provided at the junction between the front upper body 11 and the front lower body 12. A clearance area 24 is formed on the side curtain airbag 20 to accommodate the connection portion 110. Furthermore, the first air outlet 22 and the second air outlet 23 are arranged on either side of the clearance area 24. In other words, the side curtain airbag 20 uses the clearance area 24 to provide clearance for the connection portion 110 formed between the front upper body 11 and the front lower body 12. This allows the side curtain airbag 20 to form the second air outlet 23 at the location of the front lower body 12.

[0040] It should be noted that the above-mentioned connecting portion 110 specifically refers to the connecting portion formed by the front bumper upper body 11 and the front bumper lower body 12 at the location of the side air curtain 20. The specific connection structure of the connecting portion 110 can adopt the conventional method of the existing front bumper, which will not be elaborated here.

[0041] like Figure 4As shown, the side curtain airbag 20 includes a lower shell 210 and an upper shell 220. The upper shell 220 is connected to the lower shell 210 by a snap-fit ​​connection. That is, the side curtain airbag 20 can be assembled into a single piece by snap-fitting the upper shell 220 and the lower shell 210. This facilitates the production of the side curtain airbag 20 and reduces costs. Here, the upper air inlet 21, the first air outlet 22, and the second air outlet 23 of the side curtain airbag 20 are all formed by enclosing the upper shell 220 and the lower shell 210. The upper shell 220 and the lower shell 210 can be integrally injection molded from a plastic material. It should be noted that the specific snap-fit ​​structure and snap-fit ​​position between the upper shell 220 and the lower shell 210 can be specifically configured according to the connection requirements between the upper shell 220 and the lower shell 210, and will not be elaborated here.

[0042] In one embodiment, the side air curtain 20 is connected to the front bumper upper body 11 in a screw connection manner, and an assembly connection between the side air curtain 20 and the front bumper upper body 11 is realized, which facilitates the assembly connection of the side air curtain 20 on the front bumper upper body 11.

[0043] like Figures 2 to 4 As shown, a first extending protrusion 111 is formed on the front bumper upper body 11, and a second extending protrusion 25 is formed on the side curtain airbag 20. The second extending protrusion 25 is arranged corresponding to the first extending protrusion 111. When the side curtain airbag 20 is abutted against the front bumper upper body 11, the second extending protrusion 25 can be aligned with the corresponding first extending protrusion 111. The second extending protrusion 25 and the first extending protrusion 111 are then screwed together using the first bolt 101, ultimately completing the assembly connection between the side curtain airbag 20 and the front bumper upper body 11. It should be noted that the number and position of the first extending protrusion 111 on the front bumper upper body 11 can be specifically set according to the specific requirements for assembling and fixing the side curtain airbag 20 to the front bumper upper body 11, and will not be elaborated here.

[0044] In one embodiment, the side air curtain 20 is connected to the front lower body 12 in a screw connection manner, and an assembly connection between the side air curtain 20 and the front lower body 12 is realized, which facilitates the assembly connection of the side air curtain 20 on the front lower body 12.

[0045] like Figures 2 to 4 As shown, the assembly connection method between the side air curtain 20 and the front bumper lower body 12 is the same as the assembly connection method between the side air curtain 20 and the front bumper upper body 11. Specifically, a third extension convex plate 121 can be formed on the front bumper lower body 12, and a fourth extension convex plate 26 corresponding to the third extension convex plate 121 can be formed on the side air curtain 20. The second bolt 102 is used to connect and fix the fourth extension convex plate 26 and the third extension convex plate 121 that are abutted together, so as to finally realize the assembly connection between the front bumper lower body 12 and the side air curtain 20.

[0046] like Figure 2 As shown, the front bumper 100 also includes a decorative member 30, which is positioned at the air inlet 21 of the side curtain airbag 20 to shield the side curtain airbag 20. In other words, the front bumper 100 uses the decorative member 30 to shield the side curtain airbag 20 from being mounted on the front bumper body 10. The decorative member 30 is fixedly connected to the front bumper upper body 11 and the side curtain airbag 20, respectively.

[0047] In one embodiment, the decorative component 30 is respectively plugged into and matched with the front bumper upper body 11 and the side air curtain 20, and this is used as a guide to assemble and position the decorative component 30 with the front bumper upper body 11 and the side air curtain 20. This facilitates the assembly connection of the decorative component 30 between the side air curtain 20 and the front bumper upper body 11, and ensures the assembly accuracy of the decorative component 30 during assembly.

[0048] like Figure 2 As shown, the front bumper upper body 11 is formed with a plurality of protruding plates 112, and the decorative member 30 is provided with a plurality of through slots 31. The protruding plates 112 correspond one-to-one with the through slots 31, and the protruding plates 112 can be plugged into and fit with the corresponding through slots 31, thereby achieving plug-in fit between the front bumper upper body 11 and the decorative member 30. Here, the plurality of through slots 31 are sequentially spaced along the circumferential direction of the decorative member 30.

[0049] In one embodiment, the side air curtain 20 is provided with a snap-fit ​​groove (not shown) on one side in the thickness direction of the side air curtain 20, and the side air curtain 20 can be plugged into and matched with the corresponding clip plate (not shown) on the decorative component 30 through the snap-fit ​​groove, thereby realizing the plug-fitting between the side air curtain 20 and the decorative component 30.

[0050] like Figure 2 As shown, the decorative member 30 is screwed to the side curtain airbag 20, thereby facilitating assembly and connection between the decorative member 30 and the side curtain airbag 20. Here, the side curtain airbag 20 has a protruding plate 27 formed on the other side of the side curtain airbag 20 in the thickness direction. When the side curtain airbag 20 and the decorative member 30 are plugged into each other, the protruding plate 27 on the side curtain airbag 20 abuts against the decorative member 30. A third bolt 103 can then be passed through the protruding plate 27 and screwed to the decorative member 30, thereby securing the side curtain airbag 20 to the decorative member 30.

[0051] In one embodiment, two side curtain airbags 20 are configured, and the two side curtain airbags 20 are arranged on the left and right sides of the front bumper body 10. This allows the side curtain airbags 20 on the left and right sides of the front bumper body 10 to effectively dilute and guide the air, thereby further reducing the wind resistance experienced by the vehicle equipped with the front bumper 100 during driving.

[0052] The present application also provides a vehicle, comprising the front bumper 100 described in any one of the above embodiments.
