[0007] For the air guiding component according to an embodiment of the present invention, the hardness of the wind guiding plate is less than that of the support frame, and the wind guiding plate surrounds the front side of the air inlet. When a pedestrian collides with the vehicle, the pedestrian can first come into contact with the front edge of the wind guiding plate. The material of the wind guiding plate is relatively soft, which can reduce the impact force between the pedestrian and the vehicle, so as to reduce the harm to the pedestrian's legs and body. The flow area of the wind guiding channel gradually decreases, and the wind guiding channel can be a horn-shaped structure to improve the cooling effect of the air guiding component on the radiator.
[0008] According to some embodiments of the present invention, the support frame has at least one reinforcing protrusion, and at least a part of each reinforcing protrusion is embedded in the wind guiding plate.
[0009] According to some embodiments of the present invention, the support frame includes: an upper cross beam, a right column beam, a lower cross beam, and a left column beam. The upper cross beam, the right column beam, the lower cross beam, and the left column beam are sequentially connected end to end to jointly define the air inlet; wherein, the lower cross beam has at least one energy-absorbing box, and each energy-absorbing box is connected to the wind guiding plate.
[0010] According to some embodiments of the present invention, the lower cross beam includes: a lower cross beam body connected between the left column beam and the right column beam; at least one energy absorption box including a front baffle and a plurality of energy absorption ribs. The front baffle is connected to one end of the air guide plate away from the air inlet, and the front baffle is connected to the lower cross beam body through a plurality of energy absorption ribs, and at least one weakening groove is formed in each energy absorption rib.
[0011] According to some embodiments of the present invention, each energy absorption rib is also in close contact connection with the air guide plate. The air guide plate has at least one connecting rib inserted into the energy absorption box, and adjacent two energy absorption ribs are connected by one connecting rib, so that the plurality of energy absorption ribs and at least one connecting rib form a grid-shaped energy absorption structure.
[0012] According to some embodiments of the present invention, the air guide assembly further includes: at least one damping foam, which corresponds to the energy absorption box one by one, and the damping foam covers the outside of the corresponding energy absorption box.
[0013] According to some embodiments of the present invention, the lower cross beam further includes: a connection bracket including a connection plate and a support plate. The connection plate is located between the front baffle and the lower cross beam body, and the connection plate is connected to the lower cross beam body through the support plate.
[0014] According to some embodiments of the present invention, the upper cross beam includes: an upper cross beam body connected between the left column beam and the right column beam. The upper cross beam body is provided with an engine air inlet communicating with the air guide channel; a first air inlet baffle provided in the air guide channel, and the first air inlet baffle is connected to the upper cross beam body at a position where the engine air inlet is close to the air inlet; a second air inlet baffle connected to one end of the first air inlet baffle away from the upper cross beam body, and the second air inlet baffle is opposite to and spaced from the engine air inlet.
[0015] According to some embodiments of the present invention, the air guide assembly further includes: a sealing foam connected to the support frame, and the sealing foam is wound around one side of the air inlet away from the air guide plate.

[0017] According to another embodiment of the present invention, in the front-end module, the hardness of the air deflector is less than that of the support frame. The air deflector is wound around the front side of the air inlet. When a pedestrian collides with the vehicle, the pedestrian can first come into contact with the front edge of the air deflector. Since the material of the air deflector is relatively soft, the impact force between the pedestrian and the vehicle can be reduced, thereby reducing the injuries to the pedestrian's legs and body. The flow area of the air guiding channel gradually decreases, and the air guiding channel can be in a horn-shaped structure to enhance the cooling effect of the air guiding component on the radiator. The air guiding component can achieve functions such as impact energy absorption, air guiding for the radiator, and engine air intake. The integration degree of the air guiding component is high. On the premise of the same overall vehicle size, it is beneficial to reduce the space occupied by the air guiding component in the engine compartment and improve the space utilization rate.

[0039] The air guiding assembly 10 according to the embodiments of the present invention and the front end module 100 having the same will be described in detail below with reference to the drawings.
[0040] Refer to Figure 1 and Figure 2As shown, the air guide assembly 10 according to an embodiment of the present invention includes: a support frame 1 and an air guide plate 2, the support frame 1 is formed with an air inlet 17, the hardness of the air guide plate 2 is less than the hardness of the support frame 1, the air guide plate 2 is connected to the support frame 1, the air guide plate 2 is arranged around the air inlet 17 and forms an air guide channel 22 connected to the air inlet 17, wherein, in the air inlet direction of the air inlet 17, the air guide channel 22 is located upstream of the air inlet 17, and the flow area of the air guide channel 22 gradually decreases.
[0041] in, Figures 1-5 The X direction shown is the length direction of the vehicle, that is, the front and rear direction, the Y direction is the width direction of the vehicle, that is, the left and right direction, and the Z direction is the height direction of the vehicle, that is, the top and bottom.
[0042] The air guide assembly 10 can be used in a vehicle. The air guide assembly 10 can be set between the front bumper 20 and the radiator 30 of the vehicle. The air guide assembly 10 can collect the airflow generated when the car is driving and guide it to the surface of the radiator 30 to cool the radiator 30 of the vehicle.
[0043] The air guide assembly 10 includes: a support frame 1 and an air guide plate 2. The support frame 1 can be a frame structure and formed with an air inlet 17. The support frame 1 can be a "mouth"-shaped frame or a "sun"-shaped frame. In the air inlet direction of the air inlet 17, that is, the front-to-back direction, the air guide plate 2 is located on the side of the support frame 1 away from the radiator 30. The air guide assembly 10 can guide the air to flow through the air inlet 17 to the surface of the radiator 30 to achieve cooling of the vehicle's radiator 30. It can be understood that the support frame 1 can be a PP (polypropylene) material with a relatively high hardness, such as: PP-GF2 0 (20% by weight of glass fiber is added to polypropylene) to ensure the strength of the support frame 1, so that the support frame 1 can reliably support the air guide plate 2, the hardness of the air guide plate 2 is less than the hardness of the support frame 1, the air guide plate 2 can be a soft TPV (thermoplastic vulcanized rubber) part, the Shore hardness of the air guide plate 2 is A65, in the front and rear directions, the rear edge of the air guide plate 2 is connected to the support frame 1, and the support frame 1 can fix and support the air guide plate 2. Optionally, the air guide plate 2 and the support frame 1 can be integrally formed by a two-color injection molding process to facilitate the manufacture of the air guide plate 2 and the support frame 1.
[0044] The air deflector 2 is wound around the air inlet 17 and forms an air guiding channel 22 communicating with the air inlet 17. And in the air inlet direction of the air inlet 17, the air guiding channel 22 is located upstream of the air inlet 17. That is to say, the air deflector 2 is located on the front side of the support frame 1. The air guiding assembly 10 can be arranged between the front bumper 20 and the radiator 30. When a pedestrian collides with the vehicle, the front bumper 20 is fragile and easy to deform. The pedestrian can first contact and collide with the front edge of the air deflector 2. The hardness of the air deflector 2 is less than that of the support frame 1. The material of the air deflector 2 is relatively soft, which can reduce the impact force between the pedestrian and the vehicle to reduce the injury to the pedestrian's legs and body.
[0045] The air deflector 2 is wound around the air inlet 17 and forms an air guiding channel 22 communicating with the air inlet 17. In the air inlet direction of the air inlet 17, the air inlet direction of the air inlet 17 can be Figure 2 the direction from front to back. The air guiding channel 22 is located upstream of the air inlet 17. That is to say, the air outside the vehicle can pass through the front bumper 20. The air first flows through the air guiding channel 22 and then flows into the air inlet 17, and then blows to the radiator 30. The air flowing through the radiator 30 can exchange heat with the radiator 30 to cool the radiator 30.
[0046] The flow area of the air guiding channel 22 gradually decreases. The air guiding channel 22 can be a horn-shaped structure. In the front-back direction, the inlet air flow area at the front end of the air guiding channel 22 is large to increase the air intake at the front end inlet of the air guiding channel 22, so that more air can flow into the air guiding channel 22. The outlet air flow area at the rear end of the air guiding channel 22 is small, which can accelerate the air in the air guiding channel 22 to flow into the air inlet 17, so as to increase the flow rate and velocity of the air flowing through the radiator 30, improve the heat exchange amount of the air with the radiator 30, and improve the cooling effect of the air guiding assembly 10 on the radiator 30.
[0047] For the air guiding assembly 10 according to the embodiment of the present invention, the hardness of the air deflector 2 is less than that of the support frame 1. The air deflector 2 is wound around the front side of the air inlet 17. When a pedestrian collides with the vehicle, the pedestrian can first contact and collide with the front edge of the air deflector 2. The material of the air deflector 2 is relatively soft, which can reduce the impact force between the pedestrian and the vehicle to reduce the injury to the pedestrian's legs and body. The flow area of the air guiding channel 22 gradually decreases. The air guiding channel 22 can be a horn-shaped structure to improve the cooling effect of the air guiding assembly 10 on the radiator 30.
[0048] In some embodiments of the present invention, along the air inlet direction of the air inlet 17, the thickness of the air guiding plate 2 gradually increases. In other words, the thickness of the front end of the air guiding plate 2 away from the support frame 1 is relatively thin, and the thickness of the rear end of the air guiding plate 2 close to the support frame 1 is relatively thick, so as to increase the contact area between the air guiding plate 2 and the support frame 1, enhance the connection strength between the air guiding plate 2 and the support frame 1, and reduce the risk of the air guiding plate 2 detaching from the support frame 1. At the same time, the thickness of the air guiding plate 2 gradually decreases from the rear to the front, and the collapsible amount at the front end of the air guiding plate 2 is large, which can reduce the impact on pedestrians during a collision and enhance the protection effect on pedestrians.
[0049] In some embodiments of the present invention, referring to FIG. 1 and Figure 2 As shown, the support frame 1 has at least one reinforcing protrusion 16, and at least part of each reinforcing protrusion 16 is embedded in the air guiding plate 2.
[0050] Among them, the support frame 1 has a reinforcing protrusion 16. The support frame 1 can be formed with the reinforcing protrusion 16 extending from the rear to the front. The reinforcing protrusion 16 is a part of the support frame 1, and the hardness of the reinforcing protrusion 16 is greater than that of the air guiding plate 2. The multiple reinforcing protrusions 16 can be a wavy serrated structure. The structure in which the reinforcing protrusion 16 is embedded in the air guiding plate 2 can improve the structural strength of the air guiding plate 2 and reduce the risk of deformation and shaking of the air guiding plate 2 when air flows through the air guiding channel 22.
[0051] In some embodiments, the air guiding plate 2 can form a serrated structure corresponding to the reinforcing protrusion 16, and the air guiding plate 2 and the reinforcing protrusion 16 can form an interlocking connection structure at the connection part, so as to increase the connection area between the air guiding plate 2 and the reinforcing protrusion 16 and enhance the connection strength between the air guiding plate 2 and the reinforcing protrusion 16.
[0052] In other embodiments, the air guiding plate 2 covers the outside of the reinforcing protrusion 16, so that all of each reinforcing protrusion 16 is embedded in the air guiding plate 2, so as to increase the connection area between the air guiding plate 2 and the reinforcing protrusion 16 and enhance the connection strength between the air guiding plate 2 and the reinforcing protrusion 16.
[0053] In the above embodiments, the support frame 1 has at least one reinforcing protrusion 16, and at least part of each reinforcing protrusion 16 is embedded in the air guiding plate 2, which can increase the contact area between the air guiding plate 2 and the support frame 1, reduce the risk of the air guiding plate 2 and the support frame 1 detaching, the structure of the air guiding plate 2 on the side close to the air inlet 17 is strong, and the risk of the air guiding plate 2 shaking is reduced, so as to enhance the overall stability and reliability of the air guiding assembly 10.
[0054] In some embodiments of the present invention, referring to FIG. 1- Figure 4As shown in the figure, the support frame 1 includes: an upper cross beam 11, a right column beam 14, a lower cross beam 12, and a left column beam 13. The upper cross beam 11, the right column beam 14, the lower cross beam 12, and the left column beam 13 are sequentially connected end to end to jointly define an air inlet 17. Among them, the lower cross beam 12 has at least one energy absorption box 122, and each energy absorption box 122 is connected to the air deflector 2.
[0055] Among them, the upper cross beam 11 and the lower cross beam 12 can both extend in the left - right direction, the left column beam 13 and the right column beam 14 can both extend in the up - down direction. The upper cross beam 11, the lower cross beam 12, the left column beam 13, and the right column beam 14 jointly define the air inlet 17. The upper cross beam 11, the lower cross beam 12, the left column beam 13, and the right column beam 14 can form a "mouth" - shaped structure. An air inlet 17 is formed in the middle of the support frame 1. Or, the support frame 1 can further include a middle column beam 15. The middle column beam 15 can be arranged parallel to the left column beam 13 and the right column beam 14. The upper cross beam 11, the lower cross beam 12, the left column beam 13, the right column beam 14, and the middle column beam 15 can form a "day" - shaped structure. The middle column beam 15 is connected between the upper cross beam 11 and the lower cross beam 12. The middle column beam 15 can support the middle parts of the upper cross beam 11 and the lower cross beam 12 to improve the stability of the support frame 1. At this time, the middle column beam 15 divides the air inlet 17 into two sub - air inlets.
[0056] The lower cross beam 12 has an energy absorption box 122. The energy absorption box 122 is a part of the lower cross beam 12. The hardness of the energy absorption box 122 is greater than that of the air deflector 2. The energy absorption box 122 is connected to the air deflector 2. The strength of the air deflector 2 can be improved through the hard energy absorption box 122, and the risk of the air deflector 2 shaking can be reduced.
[0057] It can be understood that during the collision between the vehicle and the pedestrian, the pedestrian's leg is the main collision position. The pedestrian's leg can collide with the air deflector 2 connected to the lower cross beam 12 at the same height. The force on the leg will change sharply and non - linearly. Referring to Figure 2 As shown in the figure, each energy absorption box 122 is connected to the lower surface of the air deflector 2. The energy absorption box 122 has a front end face. During a collision, the energy absorption box 122 can increase the contact area between the air deflector assembly 10 and the pedestrian's leg, reduce the pressure generated by the air deflector assembly 10 on the leg during the collision, and reduce the risk of leg injury caused by stress concentration, which is beneficial to avoiding injury to the pedestrian's leg. At the same time, when the energy absorption box 122 is impacted, it can absorb the energy generated by the collision through crush deformation, which is beneficial to improving the energy absorption effect of the air deflector assembly 10, reducing the collision impact force between the vehicle and the pedestrian's leg, and reducing the injury suffered by the pedestrian's leg.
[0058] In the above embodiments, the lower crossbeam 12 has at least one energy absorption box 122, and each energy absorption box 122 is connected to the air deflector 2. The energy absorption box 122 can increase the contact area between the air guiding assembly 10 and the pedestrian's leg, reduce the pressure generated by the air guiding assembly 10 on the leg during a collision, and can reduce the risk of leg injury caused by stress concentration. At the same time, the energy absorption box 122 can absorb the impact of the air deflector 2 on the leg through buckling to reduce the collision impact force between the vehicle and the pedestrian's leg and reduce the injury suffered by the pedestrian's leg.
[0059] In some embodiments of the present invention, in the up-down direction, the upper crossbeam 11 is disposed above the lower crossbeam 12, and the left column beam 13 and the right column beam 14 are connected between the upper crossbeam 11 and the lower crossbeam 12. Among them, the upper crossbeam 11, the left column beam 13, and the right column beam 14 all have at least one strengthening protrusion 16.
[0060] Specifically, the upper crossbeam 11, the left column beam 13, and the right column beam 14 all have at least one strengthening protrusion 16. That is to say, the air deflector 2 is strengthened by the strengthening protrusions 16 at the joints with the upper crossbeam 11, the left column beam 13, and the right column beam 14 to improve the strength of the air deflector 2 and reduce the risk of the air deflector 2 shaking. At the same time, when the vehicle collides with a pedestrian, the upper crossbeam 11, the left column beam 13, and the right column beam 14 avoid the main positions where collisions with pedestrians occur to reduce the risk of pedestrians being injured by the strengthening protrusions 16. The structure of the strengthening protrusions 16 is simple and convenient to process, and can reduce the manufacturing cost of the air guiding assembly 10.
[0061] In some embodiments of the present invention, referring to FIGS. 3 and Figure 4 As shown, the lower crossbeam 12 includes: a lower crossbeam body 121 and at least one energy absorption box 122. The lower crossbeam body 121 is connected between the left column beam 13 and the right column beam 14. The energy absorption box 122 includes a front baffle 1221 and a plurality of energy absorption ribs 1222. The front baffle 1221 is connected to one end of the air deflector 2 away from the air inlet 17. The front baffle 1221 is connected to the lower crossbeam body 121 through a plurality of energy absorption ribs 1222, and each energy absorption rib 1222 is provided with at least one weakening groove 12221.
[0062] Among them, in the front-rear direction, the structural strength of the air deflector 2 on the side away from the air inlet 17 is weak. That is to say, the front edge of the air deflector 2 is prone to shaking and deformation. The front baffle 1221 is connected to one end of the air deflector 2 away from the air inlet 17 to increase the strength of the front edge of the air deflector 2 and reduce the risk of the front edge of the air deflector 2 shaking in the up-down direction. At the same time, the projected area of the front baffle 1221 on the XY plane is large, that is, the end face area of the front baffle 1221 facing forward is large. When the vehicle collides with a pedestrian, the front baffle 1221 can increase the contact area between the air guiding assembly 10 and the pedestrian's leg, reduce the pressure generated by the air guiding assembly 10 on the leg during a collision, and can reduce the risk of leg injury caused by stress concentration.
[0063] The front baffle 1221 is connected to the lower crossbeam body 121 through a plurality of energy-absorbing ribs 1222. Each energy-absorbing rib 1222 is provided with at least one weakening groove 12221. The structural strength of the energy-absorbing rib 1222 at the position of the weakening groove 12221 is relatively weak. The weakening groove 12221 is prone to deformation and fracture during a collision. The energy-absorbing rib 1222 can break at the weakening groove 12221 and gradually collapse to absorb energy, so that the front baffle 1221 gradually moves backward and buffers the impact on the pedestrian's leg, reducing the injury to the pedestrian's leg.
[0064] It should be noted that the arrangement of the energy-absorbing ribs 1222 can be defined by simulation means. Refer to Figure 3 As shown, the lower crossbeam 12 includes a lower crossbeam body 121 and three energy-absorbing boxes 122. The three energy-absorbing boxes 122 are arranged at intervals in the left-right direction. Each energy-absorbing box 122 includes a front baffle 1221 and four energy-absorbing ribs 1222. That is to say, the lower crossbeam body 121 is connected with twelve energy-absorbing ribs 1222 in the left-right direction. At the same time, each energy-absorbing rib 1222 is provided with two weakening grooves 12221 arranged at intervals in the front-back direction.
[0065] In the above embodiment, the energy-absorbing box 122 includes a front baffle 1221 and a plurality of energy-absorbing ribs 1222. The front baffle 1221 is connected to the end of the air deflector 2 far from the air inlet 17 to increase the strength of the front end of the air deflector 2 and reduce the risk of the front end of the air deflector 2 shaking in the up-down direction. Each energy-absorbing rib 1222 is provided with at least one weakening groove 12221. The weakening groove 12221 is prone to deformation and fracture during a collision, which is beneficial to absorbing the energy generated by the collision and reducing the injury to the pedestrian's leg.
[0066] In some embodiments of the present invention, refer to 3 and Figure 4 As shown, the energy-absorbing rib 1222 is also attached to the air deflector 2. The air deflector 2 has at least one connecting rib 21 inserted into the energy-absorbing box 122. Two adjacent energy-absorbing ribs 1222 are connected by a connecting rib 21, so that a plurality of energy-absorbing ribs 1222 and at least one connecting rib 21 form a grid-shaped energy-absorbing structure.
[0067] Among them, the energy-absorbing rib 1222 is connected between the front baffle 1221 and the lower crossbeam body 121. In the up-down direction, the upper surface of the energy-absorbing rib 1222 can be attached to and connected with the lower surface of the air deflector 2, which can increase the contact area between the energy-absorbing rib 1222 and the air deflector 2 and improve the overall strength of the air deflector 2. The air deflector 2 can extend downward to form a connecting rib 21. The connecting rib 21 is a part of the air deflector 2, and the hardness of the connecting rib 21 is less than that of the energy-absorbing rib 1222. The connecting rib 21 can be inserted into the energy-absorbing box 122. Two adjacent energy-absorbing ribs 1222 are connected by one connecting rib 21 to form a grid-shaped energy-absorbing structure, which can improve the energy-absorbing effect of the energy-absorbing box 122 during a collision. At the same time, the connecting rib 21 also increases the connecting area between the air deflector 2 and the energy-absorbing box 122 to ensure that the air deflector 2 is stably and reliably connected to the support frame 1.
[0068] Referring to Figure 4 As shown, in an energy-absorbing box 122, four energy-absorbing ribs 1222 form a grid-shaped structure through three connecting ribs 21, and there is a large collapsible energy-absorbing space in the front-back direction. When a pedestrian or a vehicle collides, two adjacent energy-absorbing ribs 1222 can approach or move away from each other in the left-right direction, and the connecting rib 21 can absorb energy through elastic deformation between two adjacent energy-absorbing ribs 1222 to prevent the grid-shaped structure from failing quickly, so that the grid-shaped structure gradually collapses backward to absorb energy and reduce the injury to the pedestrian's leg.
[0069] In some embodiments of the present invention, referring to Figures 1-4 As shown, the air guiding assembly 10 further includes: at least one damping foam 3. The damping foam 3 corresponds to the energy-absorbing box 122 one by one, and the damping foam 3 is coated on the outside of the corresponding energy-absorbing box 122.
[0070] Specifically, the number of energy-absorbing boxes 122 can be multiple, and the number of damping foams 3 is also multiple. The damping foam 3 corresponds to the energy-absorbing box 122 one by one. There is a gap between the front bumper 20 of the vehicle and the air guiding assembly 10 under normal circumstances. When the vehicle is driving on an uneven road surface, vibrations may occur. The damping foam 3 is coated on the outside of the corresponding energy-absorbing box 122 to prevent the collision noise generated by the vibration of the air deflector 2 and the front bumper 20 during driving. At the same time, the damping foam 3 is coated on the front edge of the corresponding energy-absorbing box 122, which can relieve the impact on the leg during a collision.
[0071] In some embodiments of the present invention, referring to Figure 2 and Figure 3 As shown, the lower crossbeam 12 further includes: a connecting bracket 123. The connecting bracket 123 includes a connecting plate 1231 and a supporting plate 1232. The connecting plate 1231 is located between the front baffle 1221 and the lower crossbeam body 121, and the connecting plate 1231 is connected to the lower crossbeam body 121 through the supporting plate 1232.
[0072] Specifically, the connecting bracket 123 can be connected to the vehicle body through fasteners to fix the air guiding assembly 10 on the vehicle body. The connecting bracket 123 can be configured as a cantilever structure. The connecting plate 1231 extends vertically downward from the air guiding plate 2. The front end face area of the connecting plate 1231 facing forward is relatively large, and the connecting plate 1231 is located between the front baffle 1221 and the lower crossbeam body 121. The crossbeam body can extend multiple support plates 1232 forward. The connecting plate 1231 is located behind the front baffle 1221. When a pedestrian collides with the vehicle, the front baffle 1221 can gradually collapse backward. When the energy absorption box 122 moves backward too far, the connecting plate 1231 can collide with the pedestrian's leg, increasing the contact area between the air guiding assembly 10 and the leg to reduce the injury to the pedestrian's leg.
[0073] The connecting plate 1231 is connected to the lower crossbeam body 121 through the support plate 1232. The connecting plate 1231 is a cantilever fastening surface structure. Refer to Figure 3 As shown, a set of connecting brackets 123 can be composed of one connecting plate 1231 and five support plates 1232. In this embodiment, there are four sets of connecting brackets 123. When the connecting brackets 123 are impacted, they can absorb the energy generated by the collision by collapsing and deforming in the front-rear direction through the support plates 1232, reducing the collision impact force between the vehicle and the pedestrian's leg and reducing the injury to the pedestrian's leg, and further improving the energy absorption effect of the air guiding assembly 10.
[0074] In some embodiments of the present invention, refer to Figure 1 、 Figure 2 and Figure 5 As shown, the upper crossbeam 11 includes: an upper crossbeam body 111, a first air intake baffle 112, and a second air intake baffle 113. The upper crossbeam body 111 is connected between the left column beam 13 and the right column beam 14. The upper crossbeam body 111 is provided with an engine air intake port 1111 communicating with the air guiding channel 22. The first air intake baffle 112 is arranged in the air guiding channel 22 and is connected to the upper crossbeam body 111 near the air inlet 17 of the engine air intake port 1111. The second air intake baffle 113 is connected to one end of the first air intake baffle 112 away from the upper crossbeam body 111, and the second air intake baffle 113 is opposite to and spaced from the engine air intake port 1111.
[0075] Among them, the upper crossbeam body 111 is provided with an engine air intake port 1111 communicating with the air guiding channel 22. The engine air intake port 1111 can be connected to the engine intake pipe 40. The first air intake baffle 112 is arranged in the air guiding channel 22 to supply sufficient air intake to the engine by using the air flowing through the air guiding channel 22.
[0076] The first intake baffle 112 and the second intake baffle 113 can be integrally formed by injection molding. In the gravity direction, i.e., the up-and-down direction in the figure, the first intake baffle 112 is connected to the upper beam body 111 near the air inlet 17 of the engine at the air inlet of the engine 1111, and the second intake baffle 113 is connected to one end of the first intake baffle 112 away from the upper beam body 111. Moreover, the second intake baffle 113 is opposite and spaced from the air inlet 1111 of the engine in the front-and-back direction. The first intake baffle 112 and the second intake baffle 113 are connected to form an L-shaped cantilever structure. In the up-and-down direction, the first intake baffle 112 and the second intake baffle 113 can divide the air into upper and lower regions, preventing heavier debris such as rain and snow from entering the engine through the air inlet 1111 of the engine, separating the air and the debris, which is conducive to achieving air partition filtration. At the same time, in the front-and-back direction, the second intake baffle 113 can increase the contact area when a pedestrian and the air guiding assembly 10 collide, and can reduce the impact of the air guiding assembly 10 on the pedestrian. The first intake baffle 112 and the second intake baffle 113 can be arranged on the side away from the lower beam body 121, and can avoid the leg impact area in the X direction to prevent the pedestrian's legs from being injured.
[0077] It should be noted that the upper beam 11 may further include a plurality of intake connection plates 114. One end of the intake connection plate 114 is connected to the upper beam body 111 at the upper edge of the air inlet 1111 of the engine, and the other end is connected to the second intake baffle 113, improving the connection stability among the upper beam body 111, the first intake baffle 112, and the second intake baffle 113, which is conducive to enhancing the strength of the structure of the upper beam 11 and preventing the first intake baffle 112 and the second intake baffle 113 from being damaged and affecting the engine intake efficiency.
[0078] In some embodiments of the present invention, referring to Figure 1 and Figure 2 as shown, the air guiding assembly 10 further includes: a sealing foam 4, the sealing foam 4 is connected to the support frame 1, and the sealing foam 4 is wound around the side of the air inlet 17 facing away from the air guiding plate 2.
[0079] Among them, the sealing foam 4 has advantages such as sealing, sound insulation, and support. The sealing foam 4 can be adhesively bonded to the support frame 1 in a complete circle. The sealing foam 4 is wound around the side of the air inlet 17 facing away from the air guide plate 2. The outer frame of the radiator 30 is in contact with the sealing foam 4. It can be understood that if there is a gap between the support frame 1 and the radiator 30, the waste heat of the engine can enter the air guide assembly 10 through the gap, and heat exchange can occur between the waste heat of the engine and the air guide assembly 10. The sealing foam 4 can seal the gap between the radiator 30 and the support frame 1 to prevent the hot air from flowing back to the radiator 30, improve the cooling effect of the air guide assembly 10 on the radiator 30. At the same time, when the sealing foam 4 is under pressure or deformed, the thickness of the sealing foam 4 can vary within an allowable range, and the cumulative tolerance between the air guide assembly 10 and the radiator 30 can be absorbed.
[0080] In the above embodiment, the sealing foam 4 is connected to the support frame 1, and the sealing foam 4 is wound around the side of the air inlet 17 facing away from the air guide plate 2. The sealing foam 4 can seal the gap between the radiator 30 and the sealing foam 4 to prevent the hot air from flowing back to the radiator 30, improve the cooling effect of the air guide assembly 10 on the radiator 30. At the same time, the cumulative tolerance between the air guide assembly 10 and the radiator 30 can be absorbed.
[0081] Refer to Figure 1 As shown, according to another embodiment of the present invention, the front-end module 100 includes: a front bumper 20, a radiator 30, and the above-mentioned air guide assembly 10. The air guide assembly 10 is provided between the front bumper 20 and the radiator 30, and the air guide plate 2 is located on the side of the support frame 1 facing away from the radiator 30.
[0082] According to another embodiment of the present invention, the hardness of the air guide plate 2 of the front-end module 100 is less than the hardness of the support frame 1. The air guide plate 2 is wound around the front side of the air inlet 17. When a pedestrian collides with the vehicle, the pedestrian can first come into contact with the front edge of the air guide plate 2. The material of the air guide plate 2 is relatively soft, which can reduce the impact force between the pedestrian and the vehicle, so as to reduce the injury to the pedestrian's legs and body. The flow area of the air guide channel 22 gradually decreases. The air guide channel 22 can be a horn-shaped structure to improve the cooling effect of the air guide assembly 10 on the radiator 30. The air guide assembly 10 can achieve functions such as collision energy absorption, guiding air to the radiator 30, and meeting the engine intake. The integration degree of the air guide assembly 10 is high. On the premise of the same vehicle body size, it is beneficial to reduce the space occupied by the air guide assembly 10 in the engine compartment and improve the space utilization rate.
[0083] Specifically, the front bumper 20 and the air guide plate 2 of the air guide assembly 10 can be connected by abutting. The front bumper 20 can fix the air guide plate 2 in both the front-rear direction and the up-down direction to improve the stability of the air guide plate 2.
