[0097] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0098] Please refer to Figures 1 to 9 In order to achieve the above-mentioned purpose, the present application provides an air inlet grille 10, which comprises a frame 11 and a grille blade 12. The grille blade 12 is rotationally connected to the frame 11, and the frame 11 and the grille blade 12 form a first air inlet 13. Wherein, the frame 11 forms a second air inlet 14, which can communicate the outside environment and the air inlet channel 24 of the engine of the fairing 20.

[0099] The present application sets the second air inlet 14 which can communicate the outside environment and the air inlet channel 24 of the engine of the fairing 20 on the frame 11 of the air inlet grille 10. The airflow in the environment can not only enter the vehicle front assembly 100 through the first air inlet 13 formed by the grille blade 12 after passing through the front bumper grille, but also flow into the air inlet channel 24 of the engine after passing through the fairing surface of the fairing 20 through the second air inlet 14, thereby effectively solving the technical problems of high engine intake temperature and insufficient power demand caused by insufficient air intake.

[0100] In some embodiments of the present application, the first air inlet 13 also faces a part of the cooling module 50, the second air inlet 14 also faces another part of the cooling module 50, the airflow entering the air inlet channel from the first air inlet 13 can cool a part of the cooling module 50, and the airflow entering the air inlet channel from the second air inlet 14 can also cool another part of the cooling module 50, thereby increasing the air intake of the cooling module 50 far away from the first air inlet 13 and enhancing the cooling effect of the cooling module 50. In addition, the outside airflow can flow into the cooling module through the first air inlet 13 and the second air inlet 14, which can improve the uniformity of air intake.

[0101] In some embodiments of the present application, the opening degrees of the first air inlet 13 and the second air inlet 14 can be adjusted. In this way, the amount of air intake can be adjusted according to the air intake demand to meet the different performance requirements of multiple systems.

[0102] In some embodiments of the present application, the air intake grille 10 further comprises driving members 15, the opening degrees of the first air inlet 13 and the second air inlet 14 can be adjusted by the same or different driving members 15. The present application drives the grille blades 12 by means of the driving members 15 and drives the corresponding elements (not shown in the figure) to control the opening degrees of the first air inlet 13 and the second air inlet 14, which is convenient and fast.

[0103] In the present embodiment, the opening degrees of the first air inlet 13 and the second air inlet 14 are adjusted by different driving members 15.

[0104] In the present embodiment, the air intake grille 10 further comprises a connecting rod 19, the connecting rod 19 is connected to the frame 11 to divide the air intake grille 10 into multiple air intake areas, and both ends of the multiple grille blades 12 are rotatably connected to the frame 11 and the connecting rod 19 in the corresponding air intake areas. The grille blades 12 can be rotated under the driving of the driving members 15 to adjust the opening degree of the first air inlet 13. Among them, at least one driving member 15 is fixed to the connecting rod 19. The grille blades 12 in adjacent two air intake areas can be driven by the same driving member 15 or by different driving members 15.

[0105] In some embodiments of the present application, the frame 11 comprises a first sub-frame 111, the first sub-frame 111 is arranged close to the fairing 20, and the second air inlet 14 is arranged in the first sub-frame 111. In this way, the second air inlet 14 is arranged close to the fairing 20, and the external airflow can smoothly flow into the second sub-air inlet passage 62 (see below) and the air inlet passage 24 of the engine from the second air inlet 14, so as to enhance the cooling effect of the cooling module 50 far away from the first air inlet 13, and increase the air intake amount of the air inlet passage of the engine, thereby effectively solving the technical problems of high engine air intake temperature and insufficient power demand caused by insufficient air intake amount.

[0106] In some embodiments of the present application, the frame 11 further comprises a second sub-frame 112, a third sub-frame 113 and a fourth sub-frame 114, and the first sub-frame 111, the second sub-frame 112, the third sub-frame 113 and the fourth sub-frame 114 are connected end to end. The grille blades 12 are connected to the second sub-frame 112 and / or the fourth sub-frame 114.

[0107] In some embodiments of the present application, the second air inlet 14 comprises multiple sub-air inlets 141 arranged at intervals. In this way, the air intake amount can be dynamically adjusted according to the driving state of the vehicle, unnecessary energy waste can be avoided, and the aerodynamic performance can be improved. In addition, this design not only can divide the air into multiple flow beams, avoiding the airflow obstruction and vortex phenomenon that may occur in the single air inlet design, but also can make the air enter the air inlet passage more uniformly, reduce the local pressure difference, and thus improve the overall air intake efficiency.

[0108] The number of the sub-inlet ports 141 can be as many as possible under the premise of ensuring the structural strength of the air inlet grille 10.

[0109] In some embodiments of the present application, the plurality of sub-inlet ports 141 extend along a first direction X and are arranged at intervals along a second direction Y, wherein the first direction X and the second direction Y intersect, and the "outer wall" on the same side of the adjacent two sub-inlet ports 141 refers to the first edge 181 (see below) of the flange 18 (see below).

[0110] In some embodiments of the present application, the length of each sub-inlet port 141 in the first direction X is L, and 20mm≤L≤50mm.

[0111] In some embodiments of the present application, the width in the second direction Y is W, and 5mm≤W≤20mm.

[0112] In some embodiments of the present application, the spacing between the outer walls on the same side of the adjacent two sub-inlet ports 141 is D, and 10mm≤D≤20mm.

[0113] The values of L, W and D can be satisfied simultaneously, or one or two of L, W and D can be satisfied.

[0114] In the present embodiment, the first direction X can be understood as the front-rear direction, i.e. the vehicle driving direction (including forward driving and backward driving), and the second direction Y can be understood as the left-right direction, i.e. the vehicle width direction (a direction perpendicular to the vehicle driving direction). In other embodiments, the first direction X can also be different from the vehicle driving direction.

[0115] By limiting the length, width and spacing between adjacent sub-inlet ports 141, the present application can ensure the structural strength of the frame 11 of the air inlet grille 10 while ensuring the air intake amount.

[0116] In the present embodiment, the sub-inlet ports 141 are uniformly arranged along the second direction.

[0117] In some embodiments of the present application, the end of the second inlet port 14 away from the first inlet port 13 has a flange 18, which is configured to strengthen the structural strength of the air inlet grille 10 and have a flow guiding effect while ensuring the effective air inlet area unchanged.

[0118] In the present embodiment, the flange 18 is arranged on the first sub-frame 111. The height, angle and cross-sectional shape of the flange 18 are not limited, as long as the structural strength and flow guiding effect of the entire air inlet grille 10 can be strengthened while ensuring the effective air inlet area unchanged.

[0119] In the embodiment, the flange 18 comprises a first edge 181 and a second edge 182 opposite to the first edge 181, in other words, the first edge 181 and the second edge 182 are spaced apart in the second direction Y. The width W of each sub-air inlet 141 in the second direction Y can be understood as the distance between the first edge 181 and the second edge 182 of the same sub-air inlet 141. The distance D between the outer walls of the same side of the adjacent two sub-air inlets 141 can be understood as the distance between the first edges 181 of the adjacent two sub-air inlets 141.

[0120] In some embodiments of the application, the sub-air inlet 141 comprises at least one of a runway shape, a circular shape, an elliptical shape, a rectangular shape, a long rectangular shape, a cross-shaped through hole, etc. That is, the shape of the sub-air inlet 141 is not limited.

[0121] In some embodiments of the application, the air inlet grille 10 has a first air inlet mode, a second air inlet mode, a third air inlet mode and a fourth air inlet mode. When the air inlet grille 10 is in the first air inlet mode, the first air inlet 13 is open and the second air inlet 14 is closed. When the air inlet grille 10 is in the second air inlet mode, the first air inlet 13 is closed and the second air inlet 14 is open. When the air inlet grille 10 is in the third air inlet mode, the first air inlet 13 is open and the second air inlet 14 is open. When the air inlet grille 10 is in the fourth air inlet mode, the first air inlet 13 is closed and the second air inlet 14 is closed. The air inlet grille 10 is designed to have multiple air inlet modes, which can flexibly control the amount of air inlet according to the air inlet demand to meet the different performance requirements of multiple systems.

[0122] In some embodiments of the application, when the vehicle has air inlet demand of the cooling system and the air conditioning system (i.e. the case that the air volume demand of the cooling system and the air conditioning system is relatively large), the air inlet grille is in the first air inlet mode; when the vehicle has engine air inlet demand (i.e. the case that the engine air inlet demand is relatively large), the air inlet grille is in the second air inlet mode; when the vehicle has air inlet demand of the cooling system, the air conditioning system and the engine (i.e. the case that the demand of each system for air volume is relatively large when the vehicle is in a high temperature environment), the air inlet grille is in the third air inlet mode; when the vehicle has no heat dissipation demand (i.e. the case that the ambient temperature of the vehicle is relatively low or the speed of the vehicle is relatively high but the heat dissipation demand of each system is not large), the air inlet grille is in the fourth air inlet mode. Through the control of the controller on the opening and closing states of the grille blades 12 and the sub-air inlets 141, the optimal energy consumption of the vehicle can be achieved under the premise of meeting the cooling demand, the air conditioning demand and the power demand of the vehicle.

[0123] In some embodiments of the present application, when the air intake grille is in the first air intake mode, the grille blades include a first sub-air intake mode, a second sub-air intake mode and a third sub-air intake mode; when the air intake grille is in the first sub-air intake mode, the grille blades are fully opened; when the air intake grille is in the third sub-air intake mode, the opening angle of the grille blades is a certain value between fully closed and fully opened; when the air intake grille is in the third sub-air intake mode, the opening angle of the grille blades is dynamically changed. In this way, the opening degree of the first air inlet 13 can be flexibly controlled according to cooling demand and air conditioning demand to meet different cooling demand and air conditioning demand.

[0124] In some embodiments of the present application, when the air intake grille is in the second air intake mode, the opening mode of the sub-air inlets 141 of the second air inlets 14 has infinite cases. Specifically, whether each sub-air inlet 141 is opened and the opening angle can be determined by the signal transmitted by the vehicle controller to the controller on the first sub-frame 111 (upper frame) for controlling the opening degree of the second air inlets 14.

[0125] Please refer to Figures 1 to 9 , in a second aspect, the present application also provides a vehicle front bumper assembly 100, the vehicle front bumper assembly 100 includes an air intake grille 10 and a fairing 20 located on one side of the air intake grille 10. Wherein, the fairing 20 has an engine air inlet 24, and the second air inlet 14 can communicate the outside environment and the engine air inlet 24.

[0126] By setting the second air inlet 14 capable of communicating the outside environment and the engine air inlet 24 of the fairing 20 on the frame 11 of the air intake grille 10, the airflow in the environment can not only enter the vehicle front bumper assembly 100 through the first air inlet 13 formed by the grille blades 12 after passing through the front bumper grille, but also flow into the engine air inlet 24 through the fairing surface of the fairing 20 after passing through the second air inlet 14, thereby effectively solving the technical problems of high engine intake temperature and insufficient power demand caused by insufficient air intake.

[0127] In some embodiments of the present application, the fairing 20 and the air intake grille 10 overlap in the third direction Z. The third direction Z intersects with the second direction Y and the first direction X respectively. In this embodiment, the first direction X, the second direction Y and the third direction Z form a three-dimensional coordinate system. In addition, the air intake grille 10 and the fairing 20 are mounted in a split type by overlapping in the up-down direction, which is simple to assemble.

[0128] In some embodiments of the present application, the shroud 20 further has a guide cavity 25, and the second air inlet 14 is in communication with the guide cavity 25. In the present embodiment, when the second air inlet 14 is open, the second air inlet 14 is in communication with the guide cavity 25, and when the second air inlet 14 is closed, the second air inlet 14 is not in communication with the guide cavity 25. The guide cavity 25 can guide the gas entering through the second air inlet 14, and can increase the system air intake.

[0132] In other embodiments, the extension direction of the second air inlet 14 can also be not parallel to the third direction Z.

[0134] In some embodiments of the present application, one end of the first guide surface 21 can be in contact with the first sub-frame 111, or can not be in contact with the first sub-frame 111.

[0135] In some embodiments of the present application, the shape of each guide surface of the shroud 20 can be a plane, an inclined surface, a curved surface, or other shapes under the condition of ensuring the process, assembly, and sealing.

[0136] In the embodiment, the first flow guide surface 21, the second flow guide surface 22, the third flow guide surface 23 and the fourth flow guide surface 26 are respectively a front flow guide surface, a left flow guide surface, a right flow guide surface and an upper flow guide surface. That is, one end of the front flow guide surface is arranged separately from the first sub-frame 111, and the convex portion 202 is connected with the left flow guide surface and the upper flow guide surface.

[0137] In some embodiments of the present application, the vehicle front protection assembly 100 further comprises a bumper beam 30 and a front end module 40, and the frame 11 of the air inlet grille 10 is fixedly connected with the bumper beam 30 and the front end module 40, so as to ensure the mounting stability of the air inlet grille 10, and the air inlet grille 10 is simple in assembly manner and can be completed without hoisting the vehicle to a high position.

[0138] In some embodiments of the present application, the first sub-frame 111 of the air inlet grille 10 is fixedly connected with the bumper beam 30, and the second sub-frame 112, the third sub-frame 113 and the fourth sub-frame 114 of the air inlet grille 10 are respectively fixedly connected with the front end module 40.

[0139] In some embodiments of the present application, the flow guide cover 20 is fixedly connected with the bumper beam 30 and the front end module 40, so as to ensure the mounting stability of the flow guide cover 20, and the flow guide cover 20 is simple in assembly manner and can be completed without hoisting the vehicle to a high position.

[0140] In some embodiments of the present application, the first flow guide surface 21 of the flow guide cover 20 is fixedly connected with the bumper beam 30, and the second flow guide surface 22, the third flow guide surface 23 and the fourth flow guide surface 26 are respectively fixedly connected with the front end module 40.

[0141] In some embodiments of the present application, the vehicle front protection assembly 100 further comprises a front bumper (not shown in the figure), and the bumper beam 30 is located on the side of the flow guide cover 20 and the air inlet grille 10 away from the front bumper. That is, the integrated flow guide cover 20 is located in front of the bumper beam 30 and overlaps the first sub-frame 111 of the air inlet grille 10 below, so that the distance between the first flow guide surface 21 (front flow guide surface) of the flow guide cover 20 and the cooling module 50 is increased, the volume of the entire air inlet passage 60 is increased, the air inlet resistance is reduced, the airflow is beneficial to diffusion and flow to the upper side, and good cooling effect is achieved.

[0142] In some embodiments of the present application, the front bumper assembly 100 further comprises a cooling module 50 fixedly connected to the front end module 40 and facing the air inlet grille 10 and the air deflector 20. In this way, the airflow in the environment can enter the air inlet channel 60 from the first air inlet 13 after passing through the air inlet grille 10 and flow into the part of the cooling module 50 opposite the air inlet grille 10, and the airflow in the environment can also enter the air inlet channel 60 from the second air inlet 14 and flow into the part of the cooling module 50 away from the air inlet grille 10 and the air inlet channel 24 of the engine after being deflected by the deflection surface of the air deflector 20, thereby effectively solving the technical problems of poor cooling effect, high engine air inlet temperature, insufficient air intake, and inability to meet power demand caused by insufficient air intake at the part of the cooling module 50 away from the first air inlet 13.

[0143] In some embodiments of the present application, the air inlet grille 10, the air deflector 20, and the front end module 40 form an air inlet channel 60, which comprises a first sub-air inlet channel 61 and a second sub-air inlet channel 62. The air inlet of the first sub-air inlet channel 61 can be in communication with the first air inlet 13 of the air inlet grille 10, and the air outlet of the first sub-air inlet channel 61 is in contact with a part of the cooling module 50. The air inlet of the second sub-air inlet channel 62 is in communication with the second air inlet 14 of the air inlet grille 10, and the air outlet of the second sub-air inlet channel 62 is in communication with the air inlet channel 24 of the engine and in contact with another part of the cooling module 50. In this way, the airflow in the environment can enter the first sub-air inlet channel 61 from the first air inlet 13 after passing through the air inlet grille 10 and flow into the part of the cooling module 50 opposite the air inlet grille 10, and the airflow in the environment can enter the second sub-air inlet channel 62 from the second air inlet 14 and flow into the air inlet channel 24 of the engine after being deflected by the deflection surface of the air deflector 20, thereby effectively solving the technical problems of high engine air inlet temperature, insufficient air intake, and inability to meet power demand.

[0144] Specifically, when the first air inlet 13 and the second air inlet 14 are opened simultaneously, the entire front bumper assembly 100 has two air inlet channels, i.e., the first sub-air inlet channel 61 and the second sub-air inlet channel 62. From the airflow flowing into the vehicle, a part of the airflow flows into the cooling module 50 from the first sub-air inlet channel 61 after passing through the first air inlet 13 (the grille blade 12), and another part of the airflow flows into the upper-middle part of the cooling module 50 and the air inlet channel 24 of the engine from the second sub-air inlet channel 62 after passing through the second air inlet 14. Through this structure, the following technical effects are achieved: first, the volume of the air inlet channel 60 is increased, and the system air inlet resistance is reduced, so that more effective airflow flows into the air inlet channel 60 from the outside at the same vehicle speed and fan speed; second, the air inlets of the first sub-air inlet channel 61 and the second sub-air inlet channel 62 can both flow into the cooling module 50, the air inlet uniformity is improved, and the heat exchange amount and heat exchange efficiency of the cooling module 50 are enhanced; third, the air in the second sub-air inlet channel 62 meets the engine air inlet requirement, effectively reduces the original air inlet temperature of the engine, and ensures the power performance of the engine; and fourth, the second air inlet 14 effectively utilizes the ineffective area of the front bumper directly facing the crash beam 30, and increases the system air inlet amount.

[0145] Specifically, when the grille blade 12 (the first air inlet 13) of the air inlet grille 10 is closed, the entire front bumper assembly 100 has only the second sub-air inlet channel 62. From the airflow flowing into the vehicle, the airflow flows into the air inlet channel 24 of the engine from the second sub-air inlet channel 62 after passing through the upper second air inlet 14 of the air inlet grille 10, so as to ensure the power performance of the vehicle in the engine driving mode.

[0146] In some embodiments of the present application, the air outlet of the second sub-air inlet channel 62 is directly opposite another part of the cooling module 50. In this way, the airflow in the environment can enter the second sub-air inlet channel 62 from the second air inlet 14 after passing through the front bumper grille, and flow into the part of the cooling module 50 away from the air inlet grille 10 after being guided by the guide surface of the guide cover 20, thereby effectively solving the technical problem of poor cooling effect caused by small air inlet amount at the part of the cooling module 50 away from the first air inlet 13.

[0147] In some embodiments of the present application, the crash beam 30 is located in the air inlet channel 60. Specifically, the air inlet grille 10 and the guide cover 20 are installed in a split type in an upper-lower joint manner in front of the crash beam 30, and the crash beam 30 is wrapped inside the entire air inlet channel 60. Compared with the design in which the crash beam is located in front of the guide cover, in the present case, the crash beam 30 is arranged in the air inlet channel 60, i.e., arranged behind the guide cover 20, the distance between the first guide surface 21 of the guide cover 20 and the cooling module 50 is increased, the volume of the entire air inlet channel 60 is increased, and the air inlet resistance is reduced, thereby effectively solving the above problems of small volume of the air inlet channel, large resistance, and poor cooling effect caused by the arrangement of the crash beam in front of the guide cover, which is not conducive to the diffusion and flow of the airflow upward.

[0148] In some embodiments of the present application, the vehicle front bumper assembly 100 further comprises a blocking block 70 for sealing the gap between the air inlet grille 10, the air deflector 20, the crash beam 30 and the cooling module 50, and located on the side of the crash beam 30 away from the front bumper of the vehicle. Since the distance between the air inlet grille 10 and the air deflector 20 is large, the blocking block 70 can not only play a connecting role, but also play a certain sealing role.

[0149] In some embodiments of the present application, the upper end of the blocking block 70 is connected with the air deflector 20, the lower end of the blocking block 70 is connected with the air inlet grille 10, the front end of the blocking block 70 is connected with the crash beam 30, and the rear end of the blocking block 70 is connected with the cooling module 50.

[0150] In some embodiments of the present application, the air inlet grille 10 is sealed with the front bumper, the crash beam 30, the cooling module 50 and the blocking block 70 by the first sealing member 81 respectively.

[0151] In some embodiments of the present application, the air deflector 20 is sealed with the air inlet grille 10, the crash beam 30, the front end module 40, the cooling module 50 and the blocking block 70 by the second sealing member 82 respectively.

[0152] Wherein, through the action of the first sealing member 81, the second sealing member 82 and the blocking block 70, the sealing condition between each part of the vehicle front bumper assembly 100 is good, the loss of air intake amount flowing from the front bumper into the air intake passage 24 of the cooling module 50 and the engine is reduced, and the air amount of high-temperature air in the front compartment flowing back into the air intake passage 60 is reduced.

[0153] In some embodiments of the present application, the vehicle front bumper assembly 100 further comprises a front bumper grille (not shown in the figure) located on one side of the air inlet grille 10. Air flow can enter the first air inlet 13 and the second air inlet 14 through the front bumper grille.

[0154] In some embodiments of the present application, the vehicle front bumper assembly 100 further comprises two energy absorption boxes 90, one end of each of the two energy absorption boxes 90 is connected with the two ends of the crash beam 30 respectively, and the other end is connected with the longitudinal beam of the vehicle, playing a role of absorbing collision energy.
