Description

Technical Field

[0001] The present invention relates to the technical field of automotive front bumper design, and particularly relates to an automotive front bumper assembly and a vehicle. Background Art

[0002] During the driving process of a vehicle, especially when driving at high speed, eddy currents will be formed by the ambient air flow near the bottom of the vehicle body, increasing the wind resistance. Air resistance is the main component of the total driving resistance of the vehicle. Reducing wind resistance can greatly save energy and increase the mileage per unit. When the vehicle is driving, the air flow in front of the vehicle will flow in four directions after contacting the vehicle surface, namely the roof, the bottom, and both sides. The distribution and attachment of the air flow in these four directions have a significant impact on the overall wind resistance of the vehicle. Among them, the front bumper of the vehicle is located on the front end face directly facing the wind, and has a great impact on the wind resistance during vehicle driving.

[0003] As the largest decorative part of the front face of the vehicle in terms of size and area, in order to show individuality, features such as pits, protrusions, hollow-outs, and ridges are set in areas such as the grille and fog lights of the vehicle front bumper to enrich the front face shape. However, the styling features set in areas such as the bumper grille and fog lights are very likely to cause air flow separation. After separation, the air flow and the turbulent air flow outside the downstream wheels affect each other, greatly increasing the wind resistance.

[0004] In the prior art, such as a low-wind-resistance front bumper assembly with the patent number CN119428518A and a vehicle body assembly having the low-wind-resistance front bumper assembly; including a front bumper body, the front bumper body includes an upper bumper body and a lower bumper body connected to the upper bumper body; the upper bumper body and the lower bumper body adopt a split design; a flow guiding structure for reducing wind resistance is provided on the front bumper body; the front bumper body disclosed in the present invention is designed in a split manner with the upper bumper body and the lower bumper body, which facilitates the production and processing of the front bumper body and avoids the difficulty of injection molding of the integral front bumper body; at the same time, it avoids the shrinkage marks that are likely to appear at the corners due to the over-large size of the integral front bumper body; in addition, the flow guiding structure disclosed in the present invention can reduce the running wind resistance of the front bumper assembly; thereby reducing the overall vehicle running wind resistance; thus, during subsequent use, the overall vehicle wind resistance can be reduced, and then the overall vehicle energy consumption can be reduced, and the overall vehicle cruising range can be increased.

[0005] However, one end of the spoiler is connected to the lower bumper body, and the other end extends freely. One end of the spoiler at the free end of the spoiler outer plate is spaced from the outer side surface of the front bumper body to form an open air duct. The spoiler is an added part and requires an additional design of the installation structure, which has problems affecting the integrity and stability of the vehicle front bumper.

[0047] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0048] The embodiment of this application provides an automotive front bumper assembly and a vehicle, which can solve the problem in the prior art that one end of a spoiler is connected to the lower bumper body, and the other end extends freely. One end of the spoiler at the free end of the flow guiding outer plate is spaced from the outer side surface of the front bumper body to form an open air duct. The spoiler is an added part and requires an additional installation structure, which affects the integrity and stability of the vehicle front bumper.

[0049] As Figure 1 、 Figure 2 、 Figure 5 and Figure 14 shown, on the one hand, this application provides an automotive front bumper assembly, which includes:

[0050] Upper front bumper assembly 1;

[0051] The front bumper lower assembly 2 is disposed on the lower side of the front bumper upper assembly 1. The front bumper lower assembly 2 includes a lower assembly housing 3 and an air duct inner plate 4. The lower assembly housing 3 is connected to the front bumper upper assembly 1. The two ends of the lower assembly housing 3 in the transverse direction are upturned to form a flow guiding outer plate 31, and the flow guiding outer plate 31 is located outside the edges of the two ends of the front bumper upper assembly 1 in the transverse direction. The air duct inner plate 4 is disposed inside the flow guiding outer plate 31 and includes an air duct mounting plate and an air duct bottom plate 40. The air duct mounting plate is spaced from the front bumper upper assembly 1 to form an air duct 5. The air duct bottom plate 40 is connected to the air duct mounting plate and extends along the front bumper upper assembly 1. The air duct bottom plate 40 is snap-connected to the front bumper upper assembly 1.

[0052] When designing the front bumper assembly of the vehicle, the front bumper lower assembly 2 is disposed on the lower side of the front bumper upper assembly 1. The front bumper lower assembly 2 includes a lower assembly housing 3 and an air duct inner plate 4. The lower assembly housing 3 is connected to the front bumper upper assembly 1. The two ends of the lower assembly housing 3 in the transverse direction are upturned to form a flow guiding outer plate 31, and the flow guiding outer plate 31 is located outside the edges of the two ends of the front bumper upper assembly 1 in the transverse direction. The air duct inner plate 4 is disposed inside the flow guiding outer plate 31 and includes an air duct mounting plate and an air duct bottom plate 40. The air duct mounting plate is spaced from the front bumper upper assembly 1 to form an air duct 5. The air duct bottom plate 40 is connected to the air duct mounting plate and extends along the front bumper upper assembly 1. The air duct bottom plate 40 is snap-connected to the front bumper upper assembly 1. Since the two ends of the lower assembly housing 3 in the transverse direction are upturned to form the flow guiding outer plate 31, the air duct inner plate 4 is disposed inside the flow guiding outer plate 31, the air duct bottom plate 40 is connected to the air duct mounting plate and extends along the front bumper upper assembly 1, the air duct mounting plate, the air duct bottom plate 40 and the front bumper upper assembly 1 jointly form an open air duct 5. When the air duct 5 is in normal use, the vertical acting force of the air flow on the air duct mounting plate is transmitted to the flow guiding outer plate 31. The flow guiding outer plate 31 is integrally formed with the lower assembly housing 3, having higher stability and better integrity, and solving the problem in the prior art that one end of the spoiler is connected to the lower bumper body and the other end extends freely, and there is a gap between one end of the spoiler at the free end of the spoiler outer plate and the outer side surface of the front bumper body to form an open air duct. The spoiler is an added part and requires an additional design for the installation structure, which affects the integrity and stability of the vehicle front bumper.

[0053] As Figure 11 shown, in this example, a plurality of spaced apart spoiler grooves 311 are provided on the outer side of the flow guiding outer plate 31. The bottom of the spoiler grooves 311 is spaced from the air duct inner plate 4 by 0 to 0.5 mm. The air duct inner plate 4 is a plastic part. The cross-sectional shape of the lower assembly housing 3 is U-shaped with the opening facing the rear of the vehicle. The transverse direction is essentially the vehicle Y-axis direction.

[0054] As Figure 3 shown, in this example, the air duct mounting plate and the air duct bottom plate 40 are integrally formed. The middle of the air duct mounting plate bulges and extends along the front bumper upper assembly 1 to form the air duct bottom plate 40.

[0055] AsFigure 2 , Figure 4 and Figure 5 As shown in Figure 2 , Figure 4 and Figure 5 , in some alternative embodiments, the front side of the lower assembly housing 3 is upturned to form a front lip plate 39, and the height of the air deflector outer plate 31 in the vertical direction is higher than the height of the front lip plate 39 in the vertical direction. The air deflector outer plate 31 smoothly transitions to the front lip plate 39. The upper side edges of the air deflector outer plate 31 and the front lip plate 39 are respectively provided with an air deflector flange 322 and a front lip plate flange 321. The width of the air deflector flange 322 is smaller than the width of the front lip plate flange 321. The front lip plate flange 321 is connected to the front bumper upper assembly 1, and the end of the air duct bottom plate 40 is butted against the front lip plate flange 321.

[0056] In this embodiment, the front side of the lower assembly housing 3 is upturned to form a front lip plate 39, and the height of the air deflector outer plate 31 in the vertical direction is higher than the height of the front lip plate 39 in the vertical direction. The air deflector outer plate 31 smoothly transitions to the front lip plate 39. The upper side edges of the air deflector outer plate 31 and the front lip plate 39 are respectively provided with an air deflector flange 322 and a front lip plate flange 321. The width of the air deflector flange 322 is smaller than the width of the front lip plate flange 321. The front lip plate flange 321 is connected to the front bumper upper assembly 1, and the end of the air duct bottom plate 40 is butted against the front lip plate flange 321. The front lip plate flange 321 that is conventionally provided to be connected to the front bumper upper assembly 1 and the air duct bottom plate 40 together form the lower bottom of the air duct 5, further improving the integrity.

[0057] As Figure 4 shown, in this example, a buckle 36 is provided on the front lip plate flange 321. The maximum width of the front lip plate flange 321 appears at the position of the buckle 36, and the buckle 36 is connected to the front bumper upper assembly 1. The minimum width of the air deflector flange 322 is not less than 5 mm, and the maximum width of the front lip plate flange 321 is not greater than 30 mm. The thickness of the lower assembly housing 3 is between 2.5 and 3 mm.

[0058] As Figure 3 , Figure 4 and Figure 6 shown, in some alternative embodiments, one end of the air duct bottom plate 40 facing the front lip plate 39 is provided with a connecting step 43. The front lip plate flange 321 abuts against the connecting step 43 and is flush with the air duct bottom plate 40.

[0059] In this embodiment, one end of the air duct bottom plate 40 facing the front lip plate 39 is provided with a connecting step 43. The front lip plate flange 321 abuts against the connecting step 43 and is flush with the air duct bottom plate 40, improving the flatness of the bottom of the air duct 5, facilitating the passage of air flow, and helping to reduce wind resistance.

[0060] As Figure 6As shown, in this example, a thinning area is provided at the end of the front lip panel flanging 321 to facilitate fitting to the connecting step 43. The slit width D1 between the end of the front lip panel flanging 321 and the connecting step 43 is preferably 0.5 - 1 mm. When the air flow passes through the air duct in the forward direction, the resistance is small, and it is not easy to form whistling abnormal noises and vortices.

[0061] As Figure 7 shown, in this example, the outside of the air duct bottom plate 40 is butted against the deflector flanging 322, and the outside height of the deflector flanging 322 is higher than the height of the air duct bottom plate 40, reducing the exposure of the gap between the lower assembly housing 3 and the inner air duct plate 4.

[0062] As Figure 1 and Figure 2 shown, in some alternative embodiments, the front bumper upper assembly 1 includes:

[0063] A front bumper upper skin 6, which is connected to the front bumper lower assembly 2;

[0064] Two wheel arch assemblies 7, which are provided on the front bumper upper skin 6 and are respectively located outside the two ends of the front bumper upper skin 6 in the transverse direction. The outer surfaces of the wheel arch assemblies 7 and the front bumper upper skin 6 cooperate with the inner air duct plate 4 to form the air duct 5.

[0065] In this embodiment, the specific structure of the front bumper upper assembly 1 is described. The front bumper upper assembly 1 includes a front bumper upper skin 6 and two wheel arch assemblies 7. Among them, the front bumper upper skin 6 is connected to the front bumper lower assembly 2, and the two wheel arch assemblies 7 are provided on the front bumper upper skin 6 and are respectively located outside the two ends of the front bumper upper skin 6 in the transverse direction. The outer surfaces of the wheel arch assemblies 7 and the front bumper upper skin 6 cooperate with the inner air duct plate 4 to form the air duct 5. The shape of the wheel arch assembly 7 matches the shape of the wheel, with a simple structure and convenient manufacturing.

[0066] As Figure 1 、 Figure 10 and Figure 11 shown, in this example, the outermost surface of the front bumper upper skin 6 in the transverse direction and the outer surface of the wheel arch assembly 7 are substantially flush.

[0067] As Figure 3 、 Figure 4 、 Figure 10 、 Figure 11 、 Figure 13 、 Figure 15 and Figure 16As shown, in this example, a first fixing through hole 61 is provided on the front bumper upper skin 6, a first mounting hole 45 is provided on the air duct inner plate 4, a first mounting point 37 of the lower assembly is provided on the inner side of the lower assembly housing 3, and a reed nut 38 is provided at the first mounting point 37 of the lower assembly. The first mounting hole 45 will cover the first mounting point 37 of the lower assembly, and the center of the first mounting hole 45 coincides with the center of the hole of the reed nut 38. The mounting screw 8 sequentially passes through the first fixing through hole 61, the first mounting hole 45 and the reed nut 38 along the direction from inside the vehicle to outside the vehicle.

[0068] As Figure 4 , Figure 5 and Figure 18 shown, in this example, a second fixing through hole 62 is provided on the front bumper upper skin 6, a second mounting hole 46 is provided on the air duct inner plate 4, and a BOSS post is formed by a plastic part on the back of the second mounting hole 46 to provide a fixing point for the mounting screw 8. Another mounting screw 8 sequentially passes through the second fixing through hole 62 and the second mounting hole 46 along the direction from inside the vehicle to outside the vehicle and is tightened on the BOSS post on the back of the second mounting hole 46.

[0069] As Figure 9 , Figure 10 , Figure 11 , Figure 15 and Figure 16 shown, in some alternative embodiments, a V-shaped groove 711 is provided on the lower side of the wheel arch assembly 7, and the V-shaped groove 711 is used for clamping the air duct bottom plate 40.

[0070] In this embodiment, a V-shaped groove 711 is provided on the lower side of the wheel arch assembly 7, and the V-shaped groove 711 is used for clamping the air duct bottom plate 40. When the air duct 5 is in normal use, the vertical acting force of the air flow on the air duct bottom plate 40 can also be transmitted to the V-shaped groove 711, further improving the structural stability of the air duct 5, and the bottom surface of the formed air duct 5 is smoother, facilitating the passage of the air flow and helping to reduce the wind resistance.

[0071] In this example, the weight of the front bumper lower assembly 2 formed by the lower assembly housing 3 and the air duct inner plate 4 can be transmitted to the vehicle body through the wheel arch assembly 7 and the front bumper upper skin 6, improving the stiffness of the open air duct protruding outside the vehicle.

[0072] As Figure 11 , Figure 12 , Figure 13 and Figure 14 shown, in some alternative embodiments, the wheel arch assembly 7 includes:

[0073] Two wheel arch decorative blocks 71, which are connected to the front bumper upper skin 6, and a V-shaped groove 711 is provided on the lower side of the wheel arch decorative block 71 close to the front bumper lower assembly 2;

[0074] The wheel arch 72 is connected to the front bumper upper skin 6 and is located between two wheel arch decorative blocks 71. Both ends of the wheel arch 72 are respectively connected to the two wheel arch decorative blocks 71, and the shape of the wheel arch 72 matches the shape of the wheel.

[0075] In this embodiment, the structure of the wheel arch assembly 7 is specifically described. The wheel arch assembly 7 includes a wheel arch 72 and two wheel arch decorative blocks 71. Among them, the two wheel arch decorative blocks 71 are connected to the front bumper upper skin 6. A V-shaped groove 711 is provided on the lower side of the wheel arch decorative block 71 close to the front bumper lower assembly 2. The wheel arch 72 is connected to the front bumper upper skin 6 and is located between the two wheel arch decorative blocks 71. Both ends of the wheel arch 72 are respectively connected to the two wheel arch decorative blocks 71, and the shape of the wheel arch 72 matches the shape of the wheel. The structure is simple, and the basic structure is relatively conventional, which is convenient for manufacturing.

[0076] As Figure 9 shown, in this example, the lower bottom edge of the wheel arch decorative block 71 serves as the top edge of the V-shaped groove 711, that is, by providing a side plate on the lower side of the wheel arch decorative block 71 as the bottom edge of the V-shaped groove 711, and there is a set angle between the side plate and the lower bottom edge of the wheel arch decorative block 71 to form the V-shaped groove 711.

[0077] As Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 16 shown, in this example, the front bumper upper skin 6 is provided with a first punching hole 63, a second punching hole 64 and a plurality of third punching holes 65 arranged at intervals. The first punching hole 63 and the second punching hole 64 have a flanging structure extending towards the interior of the vehicle. The third punching hole 65 is a flat punching hole. On the side of the wheel arch decorative block 71 facing the front bumper upper skin 6, there are an upper fixing platform 717 and a lower fixing platform 716. The upper fixing platform 717 is inserted into the first punching hole 63, and the lower fixing platform 716 is inserted into the second punching hole 64. Both the upper fixing platform 717 and the lower fixing platform 716 have wedge-shaped hooks. On both sides of the upper fixing platform 717 and the lower fixing platform 716, there are limiting edges 715 and limiting platforms 714. The ends of the limiting edges 715 have arc surfaces. The limiting edges 715 are located on one side of the upper fixing platform 717 or the lower fixing platform 716, and are used to facilitate the positioning of the upper fixing platform 717 or the lower fixing platform 716 in the first punching hole 63 or the second punching hole 64. There is a gap of 0.1 - 0.2 mm between the upper fixing platform 717 or the lower fixing platform 716 and the edge of the first punching hole 63 or the second punching hole 64. The limiting platform 714 is located on the side of the limiting edge 715 away from the upper fixing platform 717 or the lower fixing platform 716. The length of the limiting platform 714 is less than the length of the limiting edge 715. The limiting platform 714 is used to abut against the appearance surface of the front bumper upper skin 6. A plurality of clamping points 725 are provided on the inner side of the wheel arch 72. The clamping points 725 correspond to the third punching holes 65 one by one, and the clamping points 725 are clamped in the third punching holes 65.

[0078] As Figure 10 and Figure 11 shown, in this example, V-shaped openings 66 are provided on the outer sides of both ends of the front bumper upper skin 6 in the transverse direction, and the V-shaped openings 66 are connected through the V-shaped grooves 711.

[0079] As Figure 15 shown, in this example, the height of the air deflector outer panel 31 is approximately the same as the height of the air duct 5. The specific parameters of the air duct 5 are adjusted according to the formula: H1≥D5 + D2×tanθ, where H1 is the height of the air duct 5, D5 is the height of the wheel arch trim block 71, D2 is the width of the air duct 5, and θ is the angle between the air duct bottom plate 40 and the wheel arch trim block 71 minus 90°, that is, the angle between the air duct bottom plate 40 and the plane perpendicular to the wheel arch trim block 71. The recommended value range of D2 is 10 - 30 mm, and the value range of θ is 45° - 60°.

[0080] As Figure 13 and Figure 17 shown, in some alternative embodiments, the two ends of the lower assembly housing 3 in the transverse direction are warped inward to form a first flanging 33. One end of the wheel arch trim block 71 facing the rear of the vehicle has an assembly surface 712 in the transverse direction, and the inner arc surface of the wheel arch 72 is warped inward to form a second flanging 721. The first flanging 33, the assembly surface 712, and the second flanging 721 are flush.

[0081] In this embodiment, the two ends of the lower assembly housing 3 in the transverse direction are warped inward to form a first flanging 33. One end of the wheel arch trim block 71 facing the rear of the vehicle has an assembly surface 712 in the transverse direction, and the inner arc surface of the wheel arch 72 is warped inward to form a second flanging 721. The first flanging 33, the assembly surface 712, and the second flanging 721 are flush. When viewed from the side of the vehicle body, the edges of the parts are flush, improving the perceived quality.

[0082] As Figure 9 , Figure 12 , Figure 15 , Figure 16 and Figure 17 shown, in some alternative embodiments, a third mounting hole 713 is provided on the upper side of the wheel arch trim block 71, and plug-in blocks 722 are provided at both ends of the wheel arch 72. The plug-in blocks 722 are used to be inserted into the third mounting hole 713.

[0083] In this embodiment, a third mounting hole 713 is provided on the upper side of the wheel arch trim block 71, and plug-in blocks 722 are provided at both ends of the wheel arch 72. The plug-in blocks 722 are used to be inserted into the third mounting hole 713, improving the connection stability between the wheel arch trim block 71 and the wheel arch 72 and preventing the wheel arch 72 from separating from the wheel arch trim block 71 under the action of air flow.

[0084] As Figure 12As shown, in this example, the plug-in block 722 is a rectangular block. Limiting ribs 724 are provided on the outer surfaces of the long sides of the plug-in block 722. A gap of 0.1 - 0.5 mm is maintained between the limiting ribs 724 and the long sides of the third mounting holes 713, improving the positioning accuracy and the clamping strength. Limiting boundaries 723 are provided on the outer sides of the short sides of the plug-in block 722. The ends of the limiting boundaries 723 have arc surfaces, facilitating positioning and installation.

[0085] As Figure 3 , Figure 4 and Figure 5 shown, in some alternative embodiments, the air duct mounting plate includes:

[0086] An air duct forming part 41, which is connected to the diversion outer plate 31 and has a shape matching that of the diversion outer plate 31. An air duct bottom plate 40 is provided on the lower side of the air duct forming part 41;

[0087] A connecting part 42, which is provided on the lower side of the air duct forming part 41 and is located below the air duct bottom plate 40. The connecting part 42 is connected to the inner side of the lower assembly housing 3.

[0088] In this embodiment, the structure of the air duct mounting plate is specifically described. The air duct mounting plate includes an air duct forming part 41 and a connecting part 42. Among them, the air duct forming part 41 is connected to the diversion outer plate 31 and has a shape matching that of the diversion outer plate 31. An air duct bottom plate 40 is provided on the lower side of the air duct forming part 41. The connecting part 42 is provided on the lower side of the air duct forming part 41 and is located below the air duct bottom plate 40. The connecting part 42 is connected to the inner side of the lower assembly housing 3, with good structural stability and further improving the integrity.

[0089] As Figure 3 , Figure 4 and Figure 5 shown, in this example, mounting bumps 34 are provided on the diversion plate flanges 322 at the top of the diversion outer plate 31. Mounting notches 49 are provided at the upper ends of the air duct forming part 41. The mounting notches 49 are arranged corresponding to the mounting bumps 34, facilitating positioning and fixing. Second mounting points 35 of the lower assembly are provided on the inner side of the lower assembly housing 3. Welding holes 47 are provided on the connecting part 42. The welding holes 47 are oblong holes. The second mounting points 35 of the lower assembly are arranged corresponding to the welding holes 47. The edges of the second mounting points 35 of the lower assembly and the welding holes 47 are closely attached. Press the second mounting points 35 of the lower assembly along the direction from the inside of the vehicle to the outside of the vehicle with a soldering iron. The second mounting points 35 of the lower assembly will melt and deform under the action of high temperature, and finally the second mounting points 35 of the lower assembly and the welding holes 47 will be fused to realize the fixed connection between the air duct inner plate 4 and the lower assembly housing 3. The first mounting points 37 of the lower assembly and the second mounting points 35 of the lower assembly are parallel in the height direction.

[0090] As Figure 3 and Figure 4As shown, in this example, on the side of the connecting part 42 facing the air guiding outer plate 31, there are multiple bosses 44. The bosses 44 and the inner wall of the lower assembly housing 3 maintain a spacing of 0 - 0.5 mm, and the height of the bosses 44 is preferably 3 - 5 mm, thereby enhancing the local stiffness of the lower assembly housing 3. When the lower assembly housing 3 is pressed from the outside of the vehicle body, the lower assembly housing 3 will be deformed by the force. When the lower assembly housing 3 contacts the bosses 44, the anti-deformation ability is enhanced. To further enhance the local stiffness of the lower assembly housing 3, structural adhesive can be used to connect between the bosses 44 and the inner wall of the lower assembly housing 3, or the number of welding points between the air duct inner plate 4 and the lower assembly housing 3 can be increased.

[0091] As Figure 3 , Figure 4 and Figure 5 shown, in this example, multiple mounting protrusions 48 are provided at intervals on the outer periphery of the air duct mounting plate, and the mounting protrusions 48 abut against the inner surface of the lower assembly housing 3.

[0092] In this example, the air duct inner plate 4 and the lower assembly housing 3 only maintain fitting and contact at the bosses 44, the first mounting holes 45, the second mounting holes 46, the welding holes 47, the mounting protrusions 48, the mounting notches 49, and the connecting steps 43. This measure avoids local interference between the inner surface of the air duct inner plate 4 and the lower assembly housing 3 due to overall contact, thereby affecting the dimensional relationship between the air duct inner plate 4 and the lower assembly housing 3.

[0093] As Figure 17 shown, in this example, S is the flow direction of air when the vehicle is moving forward. The inlet width of the air duct 5 is D3, and the middle width is D4. The width given in the cross-section C - C is D2. The widths of each cross-section may vary and need to be set according to aerodynamic simulation calculations. The inlet width D3 and the middle width D4 of the air duct 5 are preferably in the range of 10 - 30 mm, and the middle width D4 is not less than the inlet width D3 of the air duct to avoid air accumulation in the air duct, thereby weakening the effect of reducing wind resistance.

[0094] As Figure 1 , Figure 2 , Figure 5 and Figure 14 shown, on the other hand, the present application also provides a vehicle, which includes the above-mentioned automotive front bumper assembly.

[0095] When designing the front bumper assembly of the vehicle, the lower front bumper assembly 2 is arranged on the lower side of the upper front bumper assembly 1. The lower front bumper assembly 2 includes a lower assembly housing 3 and an air duct inner plate 4. The lower assembly housing 3 is connected to the upper front bumper assembly 1. The two ends of the lower assembly housing 3 in the transverse direction are upturned to form flow guiding outer plates 31, and the flow guiding outer plates 31 are located outside the edges of the two ends of the upper front bumper assembly 1 in the transverse direction. The air duct inner plate 4 is arranged inside the flow guiding outer plates 31 and includes an air duct mounting plate and an air duct bottom plate 40. The air duct mounting plate is arranged at an interval from the upper front bumper assembly 1 to form an air duct 5. The air duct bottom plate 40 is connected to the air duct mounting plate and extends along the upper front bumper assembly 1. The air duct bottom plate 40 is clamped with the upper front bumper assembly 1. Since the two ends of the lower assembly housing 3 in the transverse direction are upturned to form the flow guiding outer plates 31, the air duct inner plate 4 is arranged inside the flow guiding outer plates 31, the air duct bottom plate 40 is connected to the air duct mounting plate and extends along the upper front bumper assembly 1, the air duct mounting plate, the air duct bottom plate 40 and the upper front bumper assembly 1 jointly form an open air duct 5. When the air duct 5 is in normal use, the vertical acting force of the air flow on the air duct mounting plate is transmitted to the flow guiding outer plates 31. The flow guiding outer plates 31 and the lower assembly housing 3 are integrally formed, with relatively high stability and better integrity, solving the problems in the prior art that one end of the spoiler is connected to the lower bumper body, the other end extends freely, there is a gap between one end of the spoiler at the free end of the flow guiding outer plate and the outer side surface of the front bumper body to form an open air duct, the spoiler is an added part and requires an additional design and installation structure, which affects the integrity and stability of the vehicle front bumper.
