DETAILED DESCRIPTION

[0035] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0036] Reference below Figure 1-Figure 11 An active air intake grille according to an embodiment of the present invention is described.

[0037] Most of the existing air intake grilles are set on the inner side of the fixed grille, and because the air intake grille is installed relatively far back and is blocked by surrounding parts, the light at the air intake grille is very poor, making the parts basically invisible. Moreover, most design schemes design the ACC radar and the air intake grille independently, resulting in a large occupation of the front space of the vehicle body, affecting the overall layout; almost all air intake grille blades on the market form a relatively flat closed surface that is perpendicular to the driving direction when closed, which has a negative effect on the purpose of reducing the vehicle's wind resistance coefficient.

[0038] To this end, the present invention proposes an active air intake grille to solve the above-mentioned technical problems.

[0039] like Figure 1-Figure 11 As shown, the active air intake grille 100 includes: a grille frame 1, a plurality of blades 2 and a driving mechanism.

[0040] Among them, a radar installation opening 11 is provided in the middle of the grille frame 1, and air inlets 12 are provided on both sides, and a plurality of blades 2 are respectively provided at the air inlets 12. Specifically, the grille frame 1 adopts a frame structure, and a radar installation opening 11 is provided in the middle of the grille frame 1 for installing a radar. In this way, the radar is integrated on the active air intake grille 100. Compared with the conventional arrangement of the radar on the roof, the radar arrangement scheme of the present invention can reduce driving wind noise and improve the driving NVH experience. In addition, air inlets 12 are provided on both sides of the grille frame 1, and a plurality of blades 2 are respectively arranged at the air inlets 12 on both sides of the radar installation opening 11. In this way, the air inlet 12 can be switched between a closed state and an open state under the rotation of the blades 2.

[0041] Compared with the traditional built-in air intake grille, the present invention adopts an external active air intake grille 100, so that whether the blade 2 is open or closed can be easily observed from the outside of the vehicle, thereby improving the user experience, and more obviously reducing the vehicle's driving wind resistance, improving economy, and enhancing the vehicle's sense of technology.

[0042] Moreover, the driving mechanism includes: a driving member 3, a pull rod 4 and a first connecting rod 5. The driving member 3 is drivingly connected to the pull rod 4. The pull rod 4 and the first connecting rod 5 are respectively arranged on both sides of the blade 2 along the left and right directions, and are rotationally connected to the blade 2. The driving member 3 drives the pull rod 4 to move, and the pull rod 4 drives the blade 2 to rotate relative to the first connecting rod 5.

[0043] Specifically, the driving member 3 may be a common driving motor, and of course, other driving members 3 may be used instead. The driving member 3 may be one, driving the pull rod 4 connected to the blades 2 on both sides of the radar installation port 11 to move, or the driving member 3 may be two, respectively driving the pull rod 4 connected to the blades 2 on both sides of the radar installation port 11 to move.

[0044] Compared with the drive and transmission design in the prior art, the transmission structure is numerous and the connection is complicated. Some of them connect the two sides of the blade 2 to the grid frame, which is not convenient for disassembly and maintenance. The present drive mechanism can realize the rotation of the blade 2 only through the connection structure of the drive member 3, the pull rod 4, and the first connecting rod 5. It is not only simple in structure, but also convenient for installation and disassembly.

[0045] Taking the blade 2 on one side of the grille frame 1 as an example, a pull rod 4 is provided on one side of the blade 2 along the left-right direction, and a first connecting rod 5 is provided on the other side, and the pull rod 4 and the first connecting rod 5 are rotatably connected to the two sides of the blade 2, that is, the central axis of the blade 2 is in the left-right direction, and the blade 2 rotates around the central axis under the drive of the driving mechanism.

[0046] When the driving member 3 drives the pull rod 4 to move, the pull rod 4 drives the blade 2 to rotate relative to the first connecting rod 5. In the embodiment of the present invention, the number of driving members 3 is two, and the pull rod 4 is arranged on the side of the blade 2 close to the radar installation port 11. Correspondingly, the driving member 3 is also arranged on the side close to the radar installation port 11, and the pull rod 4 is arranged in the up and down direction, so that the driving member 3 can drive the pull rod 4 to move up and down, thereby driving the blade 2 to rotate, and then the active air intake grille 100 is in an open state or a closed state. When the active air intake grille 100 is in a closed state, the blade 2 completely covers the air inlet 12, and its main function is to block the front airflow from entering the cabin when driving at high speed, reduce driving resistance, and improve the vehicle's endurance. In addition, it can accelerate the heating speed of the water tank and the heat preservation effect at low temperatures.

[0047] Specifically, in the embodiment of the present invention, three blades 2 are arranged on one side of the grille frame 1, and three blades 2 are arranged on the other side, which are arranged symmetrically, and one set of driving mechanisms is used to drive the three blades 2 on one side of the grille frame 1, and one set of driving mechanisms is used to drive the three blades 2 on the other side of the grille frame 1. Moreover, one side of the three blades 2 located on one side of the grille frame 1 is rotatably connected to the pull rod 4, and the other side of the three blades 2 is rotatably connected to the first connecting rod 5, so that under the drive of the driving member 3, the pull rod 4 drives the three blades 2 to rotate relative to the first connecting rod 5.

[0048] In addition, when the number of the driving members 3 is two, it can be understood that the two groups of driving mechanisms are arranged on the left and right sides of the radar installation port 11, respectively. In this way, one group of driving mechanisms is used to drive the blades 2 on one side of the grille frame 1, and the other group of driving mechanisms is used to drive the blades 2 on the other side of the grille frame 1. In this way, on the one hand, the blades 2 on both sides of the grille frame 1 work independently of each other and do not affect each other. Compared with the existing fan blades, most of which only use one driving motor to drive the operation, the corresponding transmission structure design is relatively complex, which makes it easy for the driving force of the driving motor and the reaction force of the fan blade to be concentrated on the active fan blade shaft, resulting in stress concentration and the active fan blade shaft being easily broken. The driving mechanisms of the present invention are arranged on both sides of the grille frame 1, so that the blades 2 on the same side of the grille frame 1 rotate synchronously, with high consistency and stability of movement, and at the same time, the stress is dispersed, and the blades 2 are not easy to break. Compared with the traditional single motor structure, the operation is more stable and the service life is longer. On the other hand, most of the traditional drive motors are installed in the middle of the air intake grille, which is not conducive to the integration of radar. The present invention reserves a radar installation port 11 in the middle of the active air intake grille 100, and arranges drive mechanisms on both sides of the radar installation port 11. In this way, the drive mechanisms on both sides work independently and have no connection with each other, thereby leaving installation space for the radar and facilitating the assembly and use of the radar device.

[0049] Of course, when the number of driving members 3 is one, one driving member 3 drives the pull rods 4 at the blades 2 on both sides to move together, which may better achieve the same frequency rotation of multiple blades 2 and improve the customer's visual experience.

[0050] Thus, by arranging the radar installation port 11 in the middle of the grille frame 1, the active air intake grille 100 is integrated with a radar, which can effectively reduce driving wind noise and improve the NVH experience. In addition, the driving mechanism is provided with a driving member 3, a pull rod 4 and a first connecting rod 5, and through the blade 2 of the active air intake grille 100, the blade 2 can be opened or closed synchronously, with good aerodynamic performance, reducing the wind resistance of the whole vehicle, keeping the engine at the optimal horizontal temperature, reducing energy consumption, being more environmentally friendly, and having a simpler and more reasonable driving structure, convenient assembly, and lower cost.

[0051] Further, the driving mechanism also includes: a second connecting rod 6, the second connecting rod 6 and the pull rod 4 are arranged side by side in the front-to-back direction, and are arranged on the side of the grille frame 1 close to the pull rod 4, and the second connecting rod 6 is rotatably connected to one side of the blade 2 along the left-right direction. Specifically, the second connecting rod 6 and the pull rod 4 are located on the same side of the blade 2, the second connecting rod 6 and the pull rod 4 are arranged side by side in the front-to-back direction, and are arranged on the side of the grille frame 1 close to the pull rod 4, so that the second connecting rod 6 is blocked by the pull rod 4, reducing the installation space, and at the same time, the second connecting rod 6 is rotatably connected to the blade 2, so that when the pull rod 4 drives the blade 2, the two sides of the blade 2 are rotated relative to the first connecting rod 5 and the second connecting rod 6 respectively, so as to realize the flipping of the blade 2 at a certain angle. In this way, the first connecting rod 5 and the second connecting rod 6 on both sides of the blade 2 are arranged in coordination, and the stability of the blade 2 during the movement is enhanced.

[0052] Among them, two first pivoting parts 21 are provided on one side of the blade 2 along the left-right direction, and the two first pivoting parts are respectively rotatably connected with the pull rod 4 and the second connecting rod 6. In this way, two first pivoting parts 21 are provided on one side of the blade 2, so that one side of the blade 2 is rotatably connected with the pull rod 4 and the second connecting rod 6 respectively through the first pivoting parts. Specifically, the first pivoting part 21 can be a cylindrical structure, and the pull rod 4 and the first connecting rod 5 are provided with matching holes. After the cylindrical structure passes through the matching holes, a transmission shaft 7 structure is formed to rotate when needed.

[0053] Of course, the first pivot portion 21 can be a pivot hole, and the pull rod 4 and the first connecting rod 5 are provided with a cylindrical structure, and the two cooperate to form a transmission shaft 7 structure, or the first pivot portion 21 can also be other structures to achieve a rotational connection between the blade 2 and the pull rod 4 and the second connecting rod 6.

[0054] Furthermore, one end of the pull rod 4 in the up-down direction is connected to the driving member 3, and the other end of the pull rod 4 in the up-down direction is connected to the second connecting rod 6, and the first connecting rod 5 and the second connecting rod 6 are both connected to the grille frame 1. In other words, the first connecting rod 5 and the second connecting rod 6 are arranged on the grille frame 1, and are respectively connected to the two sides of the blade 2 for rotation, so that the blade 2 can rotate relative to the first connecting rod 5 and the second connecting rod 6. One end of the pull rod 4 is connected to the driving member 3, and the other end is connected to the second connecting rod 6, so that when the driving member 3 drives the pull rod 4 to move relative to the second connecting rod 6, the blade 2 can be driven to rotate stably.

[0055] In the embodiment of the present invention, after the first connecting rod 5 and the second connecting rod 6 are positioned by the positioning pins, they can be fixed to the grid frame 1 by fasteners such as self-tapping screws.

[0056] Moreover, the other side of the blade 2 in the left-right direction is provided with a second hub 22, which is a rotating shaft, and the blade 2 is rotatably connected to the first connecting rod 5 through the rotating shaft. In this way, the second hub 22 is provided on the side where the blade 2 is connected to the first connecting rod 5, and the second hub 22 can be a rotating shaft, so that the rotating shaft passes through the matching hole of the first connecting rod 5 to form a transmission shaft 7 structure, thereby realizing the rotatable connection between the blade 2 and the first connecting rod 5.

[0057] Further, a protrusion 23 is provided at one end of the rotating shaft away from the blade 2, a limiting portion 51 is provided on the first connecting rod 5, the rotating shaft is passed through the first connecting rod 5, and the protrusion 23 and the limiting portion 51 are limitedly matched. In this way, the protrusion 23 is provided at one end of the rotating shaft away from the blade 2, so that after the rotating shaft is passed through the matching hole of the first connecting rod 5, the protrusion 23 and the limiting portion 51 on the first connecting rod 5 are limitedly matched to prevent the blade 2 from moving back and forth in the direction of the central axis.

[0058] In the embodiment of the present invention, the limiting portion 51 may be a limiting rib.

[0059] In addition, the driving mechanism also includes: a transmission shaft 7, the transmission shaft 7 includes: a first connecting shaft 71, a second connecting shaft 72 and a connecting rod 73, the first connecting shaft 71 and the second connecting shaft 72 are respectively connected to the two ends of the connecting rod 73, and are perpendicular to the connecting rod 73, the first connecting shaft 71 and the second connecting shaft 72 are extended in directions away from each other relative to the connecting rod 73, the first connecting shaft 71 is drivingly connected to the output end of the driving member 3, and the second connecting shaft 72 is drivingly connected to the pull rod 4.

[0060] Specifically, after receiving the start signal from the vehicle controller, the driving member 3 drives the transmission shaft 7 to rotate. At the same time, the transmission shaft 7 is connected to the pull rod 4, that is, the pull rod 4 can start to move. When the pull rod 4 moves, it can drive the blade 2 to rotate, thereby achieving the opening and closing action.

[0061] Specifically, the first connecting shaft 71 and the second connecting shaft 72 are respectively connected to the two ends of the connecting rod 73, and the first connecting shaft 71 and the second connecting shaft 72 are respectively perpendicular to the connecting rod 73, and the first connecting shaft 71 and the second connecting shaft 72 are extended in directions away from each other relative to the connecting rod 73, so that the transmission shaft 7 is similar to a "crank" structure. In this way, the output end of the driving member 3 drives the first connecting shaft 71 to rotate, and then the second connecting shaft 72 drives the pull rod 4 to move, thereby realizing the rotation of the blade 2.

[0062] Compared with the transmission structure in the prior art, which is more complicated, in addition to designing the transmission shaft 7, a limit plate, a transmission rod and other structures are also designed. The present invention designs the transmission shaft 7 structure and makes the transmission shaft 7 directly drive connected with the pull rod 4, so that the blade 2 can be rotated relative to the first connecting rod 5 and the second connecting rod 6. The transmission structure is simple, the number of parts is reduced, and the force transmission is efficient, which greatly reduces the risk of the blade 2 breaking.

[0063] Further, the two ends of the driving member 3 are respectively connected with transmission shafts 7, and the driving member 3 drives the two transmission shafts 7 to rotate, and the two transmission shafts 7 respectively drive the pull rods 4 on both sides of the radar installation port 11 to move. In other words, when the number of the driving member 3 is one, the two ends of the driving member 3 are respectively connected with transmission shafts 7 to drive the two transmission shafts 7 to rotate, and then the two transmission shafts 7 respectively drive the pull rods 4 on both sides of the radar installation port 11 to move, so that one driving member 3 can simultaneously drive the blades 2 on both sides to rotate, ensuring the synchronous rotation of multiple blades 2.

[0064] When the number of driving members 3 is two, one driving member 3 is connected to a transmission shaft 7. The driving member 3 located on one side of the radar installation port 11 drives the transmission shaft 7 on that side to rotate, so as to drive the blades on that side to rotate. The driving member 3 located on the other side of the radar installation port 11 drives the transmission shaft 7 on that side to rotate, so as to drive the blades on that side to rotate.

[0065] In addition, the driving member 3 is fixed to the grille frame 1 through a driving member mounting bracket, wherein the driving member mounting bracket can be positioned by a positioning pin and screwed and fixed to the driving member mounting bracket.

[0066] Furthermore, the active air intake grille 100 also includes: a radar mounting bracket 8 and a vibration damping member 9, the radar mounting bracket 8 is arranged at the radar mounting opening 11, and the vibration damping member 9 is arranged on the radar mounting bracket 8 to be suitable for filling between the radar and the radar mounting bracket 8.

[0067] Specifically, the radar mounting bracket 8 is installed at the radar mounting opening 11, so that the radar is fixed on the radar mounting bracket 8. In addition, a vibration reduction member 9 is provided on the radar mounting bracket 8, such as a vibration reduction sponge, which can be attached to the installation gap between the radar mounting bracket 8 and the radar, thereby effectively achieving a vibration reduction effect and improving the safety of radar use.

[0068] In the present invention, the radar mounting bracket 8 is provided with a radar mounting hole 81 and a harness plug hole 82. The radar mounting hole 81 is used to install the radar and the harness plug is used to connect the harness of the radar for routing. In addition, the radar mounting bracket 8 is positioned with the grille frame 1 through a positioning pin and is fastened with a nut on the grille frame 1 by a self-tapping screw. In addition, a plurality of fixed mounting holes 83 are provided on the periphery of the radar mounting bracket 8 to facilitate the fastener to penetrate the fixed mounting hole 83 and fix the grille frame 1.

[0069] Furthermore, a plurality of mounting parts are arranged on the outer periphery of the grille frame 1. The plurality of mounting parts are snap-on structures and / or screw-on structures. The grille frame 1 is fixedly connected to the bumper assembly via the plurality of mounting parts.

[0070] Specifically, a first mounting portion 13 of a clamping structure is provided at one end of the grille frame 1 in the vertical direction, which is suitable for connecting with the bumper outer plate, and a second mounting portion 14 of a screwing structure is provided at one end of the grille frame 1 in the vertical direction, which is suitable for connecting with the bumper bottom guard plate 10; and a third mounting portion 15 is provided at both ends of the grille frame 1 in the vertical direction, wherein the mounting portion at one end is a clamping structure and the other end is a screwing structure, which is suitable for connecting with both ends of the bumper inner plate. In addition, a main positioning point 16 is provided in the middle of the grille frame 1, and auxiliary positioning points 17 are provided on both sides of the grille frame 1, which can be positioned by positioning pins and then fastened with nuts on the grille frame 1 by self-tapping screws, thereby ensuring that the grille frame 1 is fixedly connected to the bumper assembly.

[0071] In addition, the surface of the blade 2 facing the front of the vehicle is engraved with patterns, which can be treated with a different color from the surface, and the side of the blade 2 facing the rear of the vehicle can be provided with reinforcing ribs 24 to increase the structural strength of the blade 2.

[0072] A vehicle according to an embodiment of the second aspect of the present invention includes: an active air intake grille 100 .

[0073] Therefore, by arranging the radar installation opening 11 in the middle of the grille frame 1, the radar is integrated on the active air intake grille 100. Compared with the conventional arrangement of the radar on the roof, this radar arrangement scheme can reduce the driving wind noise and improve the NVH experience. Compared with the traditional built-in air intake grille, it has more obvious effects in reducing the driving wind resistance of the vehicle, improving economy, and enhancing the sense of technology of the vehicle. In addition, by designing at least two sets of driving mechanisms and arranging them on the left and right sides of the radar installation opening 11, respectively, the blades 2 located at the two air inlets 12 are driven to rotate, so that at least one set of driving mechanisms is used to drive the blades 2 on one side of the grille frame 1, and the other set of driving mechanisms is used to drive the blades 2 on the other side of the grille frame 1. In this way, on the one hand, the blades 2 on both sides of the grille frame 1 work independently of each other and do not affect each other. Compared with the existing fan blades, which are mostly driven by only one driving motor, the driving mechanisms of the present invention are arranged on both sides of the grille frame 1, so that the blades on the same side of the grille frame 1 can rotate. The blade 2 rotates synchronously, with high consistency and stability in motion, and at the same time, the stress is dispersed, and the blade 2 is not easy to break. Compared with the traditional single-motor structure, it runs more smoothly and has a longer service life. On the other hand, most of the traditional drive motors are installed in the middle of the air intake grille, which is not conducive to the integration of radar. The present invention reserves a radar installation port 11 in the middle of the active air intake grille 100, and arranges drive mechanisms on both sides of the radar installation port 11. In this way, the drive mechanisms on both sides work independently and will not be related to each other, thereby avoiding installation space for the radar and facilitating the assembly and use of the radar device. In addition, the second connecting rod 6 and the pull rod 4 are arranged side by side in the front-to-back direction, so that the second connecting rod 6 is blocked by the pull rod 4, reducing the installation space. At the same time, the two sides of the blade 2 rotate relative to the first connecting rod 5 and the second connecting rod 6, respectively, which enhances the stability of the blade 2 during movement. The active air intake grille 100 of the present invention, through the use of the blades 2, can realize the synchronous opening or closing of the blades 2, has good aerodynamic performance, reduces the wind resistance of the whole vehicle, keeps the engine at the optimal horizontal temperature, reduces energy consumption, is more environmentally friendly, and is simpler and more reasonable in structure, easy to assemble, and has lower cost.
