[0005] The present invention provides an active intake grill and a vehicle.

Means for Solving the Problems

[0006] The active intake grille according to the present invention includes a fixed bracket, an interlocking bracket, a driving device, a first link mechanism, and at least one intake unit. The intake unit includes a plurality of blades and a plurality of blade link mechanisms. The interlocking bracket is rotatably connected to the first end of each of the plurality of blade link mechanisms. The second end of each blade link mechanism is rotatably connected to the first end of each corresponding blade one-to-one. The second end of the blade is rotatably connected to the fixed bracket. The first end of the first link mechanism is connected to the interlocking bracket, and the second end of the first link mechanism is connected to the driving device. The driving device drives the first link mechanism to move. The first link mechanism moves the interlocking bracket. The interlocking bracket moves the blade link mechanism. As a result, the blade link mechanism moves the first end of the blade to rotate, thereby opening and closing the intake unit.

[0007] In one embodiment, an intake unit mounting port is provided on the fixed bracket. The intake unit mounting port is provided corresponding to the intake unit one-to-one. The shape of the intake unit mounting port includes at least one of a circular shape and a polygonal shape. The plurality of blades are arranged along the periphery of the intake unit mounting port.

[0008] In one embodiment, the fixed bracket is further provided with a surplus blade mounting port located between adjacent intake unit mounting ports. A blade is provided in the surplus blade mounting port.

[0009] In one embodiment, it includes a fixed bracket, an interlocking bracket, a driving device, a first link mechanism, and at least one intake unit. The fixed bracket is provided with an intake unit mounting port, and the intake unit mounting port is provided in a one-to-one correspondence with the intake unit. The intake unit includes a plurality of blades and a plurality of blade link mechanisms. The blade is provided with a first end portion and a second end portion. The second end portion of the blade is rotatably connected to the edge of the intake unit mounting port to realize the rotational connection between the blade and the fixed bracket. The first end portion of each blade is separated from the edge of the intake unit mounting port with respect to its own second end portion, and is rotatably connected to each blade link mechanism in a one-to-one correspondence. One end of each blade link mechanism is rotatably connected to each blade, and the other end of each blade link mechanism is rotatably connected to the interlocking bracket. The first link mechanism is connected to the interlocking bracket and the drive device at different positions thereof, and the first link mechanism is arranged to be driven by the drive device to move the interlocking bracket. Thereby, the blade link mechanism is moved by the interlocking bracket, and further, the blade link mechanism moves and rotates the blade, and the blade is reversed with respect to the fixed bracket to open and close the intake unit.

[0010] In one embodiment, the intake unit is arranged such that when the intake unit is in the open state, an intake passage is formed in the active intake grille between the blades of the same intake unit. The intake passage is arranged to allow air to pass through the active intake grille. When the intake unit is in the closed state, the intake passage disappears. Each blade within the same intake unit is arranged such that when the interlocking bracket moves away from the intake unit mounting port, an intake passage is formed between the blades. After the intake passage is formed, the interlocking bracket returns in a direction approaching the intake unit mounting port, and the intake passage disappears.

[0011] In one embodiment, the blade link mechanism is rotatably connected to the blade, further engages with the blade, is rotatably connected to the interlocking bracket, and further engages with the interlocking bracket.

[0012] In one embodiment, the blade link mechanism includes a main body and a first engaging portion. A first base region is provided on the main body. The first base region and the first engaging portion are connected to each other. The first engaging portion is provided in the first base region. The first engaging portion includes a first shaft portion provided in order from proximal to distal from the main body and a group of engaging portions. The group of engaging portions includes a first engaging portion and a second engaging portion provided at intervals. Both the first engaging portion and the second engaging portion are connected to the first shaft portion and are elastically deformable. A second engaging portion is provided on the blade. The group of engaging portions is engaged with the second engaging portion, and the first shaft portion is rotatably connected to the second engaging portion. The second engaging portion is located between the group of engaging portions and the main body. The group of engaging portions and the first base region limit at least a part of the second engaging portion therebetween and are arranged to cooperate to limit the detachment of the blade link mechanism from the blade.

[0013] In one embodiment, the blade link mechanism further includes a third engaging portion. A second base region is further provided on the main body. The second base region and the third engaging portion are connected to each other. The third engaging portion is provided in the second base region and includes a second shaft portion provided at intervals and a third engaging portion. A fourth engaging portion is provided on the interlocking bracket. The second shaft portion is rotatably connected to the fourth engaging portion. The third engaging portion engages with the fourth engaging portion.

[0014] In one embodiment, the blade link mechanism further includes an elastic part, and the elastic part is connected to the main body and abuts against the interlocking bracket so as to play a buffering role during the relative movement between the blade link mechanism and the interlocking bracket. At least one through region is provided in the elastic part, and the through region is used to facilitate the deformation of the elastic part close to the edge of the elastic part located on its circumferential side.

[0015] In one embodiment, the number of installed through regions is two or more, and different through regions facilitate the deformation of different positions of the elastic part. Different positions of the elastic part cause a buffering effect at different timings when the blade link mechanism and the interlocking bracket move.

[0016] In one embodiment, the active intake grille further includes a second link mechanism. The first link mechanism is located below the vehicle body of the interlocking bracket and is connected to the interlocking bracket. The second link mechanism is connected to the upper end of the vehicle body of the fixed bracket, the lower end of the vehicle body of the fixed bracket, the upper end of the vehicle body of the interlocking bracket, and the lower end of the vehicle body of the interlocking bracket. The first link mechanism is driven by the driving device, and moves the interlocking bracket forward or backward of the vehicle body to reverse the blade outside or inside the vehicle with respect to the fixed bracket, so as to be arranged to open and close the intake unit.

[0017] In one embodiment, the second link mechanism includes a first split body and a second split body that are rotatably connected. One of the first split body and the second split body is rotatably connected to the fixed bracket. The other of the first split body and the second split body is rotatably connected to the interlocking bracket.

[0018] In one embodiment, an axial region is provided on one of the first divided body and the second divided body, and a rotational connection portion is provided on the other of the first divided body and the second divided body. The rotational connection portion is rotatably connected to the axial region.

[0019] In one embodiment, the rotational connection portion is a side-opening sleeve integrally formed on one of the first divided body and the second divided body, and the axial region is a cylinder integrally formed on the other of the first divided body and the second divided body.

[0020] In one embodiment, both the first divided body and the second divided body have a U-shaped configuration. One end of the U-shaped first divided body at its opening position is rotatably connected to one of the interlocking bracket and the fixed bracket, and the other end of the U-shaped first divided body at its opening position is rotatably connected to the other of the interlocking bracket and the fixed bracket.

[0021] In one embodiment, the operation logic of the driving device includes detecting the received resistance. A component force portion protruding outward from the first divided body is provided on the circumferential side of the first divided body. The component force portion inhibits the rotation of the first divided body and generates an interaction force with the first divided body. The force applied from the first divided body received by the component force portion is transmitted to the driving device as part of the resistance.

[0022] The present application also provides a vehicle including the active intake grille described in any of the above.

[0025] Hereinafter, specific embodiments of the present invention will be described in more detail in combination with the drawings and examples. The following examples are for explaining the present invention, but not for limiting the scope of the present invention.

It is only for facilitating the explanation and simplification, and does not indicate or imply that the specified device or element must have a specific orientation and be configured or operated in a specific orientation. Therefore, it cannot be understood as a limitation of the present invention.

[0029] The term "comprise", "include", or any other variation thereof in the present invention is intended to cover non-exclusive inclusion, including other elements not expressly listed in addition to the recited elements.

[0030] In the description of this specification, terms such as "one embodiment", "several embodiments", "exemplarily", "specifically", "furthermore", "described in more detail", "preferably", "further comprises", "further includes", "optionally", or "several instances" are referred to in the description, which means that the specific features, structures, materials, or characteristics described in relation to this embodiment or instance are included in at least one embodiment or instance of the present invention.

[0031] Hereinafter, in accordance with the drawings in the embodiments of the present application, the technical aspects in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the present application.

[0032] In addition, in the description of the present application, the orientation or positional relationship indicated by terms such as "end" is based on the orientation or positional relationship shown in the drawings, and is merely for facilitating the description of the present application and simplifying the description, without indicating or implying that the specified component must have a specific orientation and be configured and operated in a specific orientation, so it cannot be understood as a limitation to the present application.

[0033] <Example 1> As shown in FIGS. 1 to 3, the present application provides a vehicle provided with an active intake grille. The active intake grille includes a fixed bracket 1, an interlocking bracket 2, a drive device 3, a first link mechanism 4, and at least one intake unit 10. An intake unit mounting port is provided on the fixed bracket 1, and the intake unit mounting ports are provided in a one-to-one correspondence with the intake units 10. In this embodiment, the intake unit 10 includes a plurality of blades 6 provided with a first end and a second end, and a plurality of blade link mechanisms 7. The second end of the blade 6 is rotatably connected to the edge of the intake unit mounting port, the first end of the blade 6 is spaced from the edge of the intake unit mounting port with respect to the second end of the blade 6, and is rotatably connected to each blade link mechanism 7 in a one-to-one correspondence. One end of each blade link mechanism 7 is rotatably connected to the corresponding blade 6, and the other end of each blade link mechanism 7 is rotatably connected to the interlocking bracket 2.

[0034] At the same time, the first link mechanism 4 in this embodiment is also connected to the interlocking bracket 2 and the drive device 3 at different positions thereof. The first link mechanism 4 is arranged to be driven by the drive device 3 and move the interlocking bracket 2. Thereby, the blade link mechanism 7 is blade-linked by the interlocking bracket 2 to rotate the blade 6, and the blade 6 is inverted with respect to the fixed bracket 1 to open and close the intake unit 10. Note that the "open" or "close" state of the intake unit 10 as described above and in this specification means that the blade 6 is inverted at an arbitrary angle into the vehicle interior. That is, all explanations regarding "open" or "close" of the intake unit 10 as described above and in this specification do not particularly mean that the intake unit 10 is opened to the maximum opening degree.

[0035] As described above, the second end of the blade 6 is rotatably connected to the edge of the intake unit mounting port, the first end of the blade 6 moves away from the edge of the intake unit mounting port with respect to the second end of the blade 6, and the first end of the blade 6 is rotatably connected to the blade link mechanism 7. Since the blade 6 can be reversed with respect to the fixed bracket 1 under the drive of the blade link mechanism 7 to open and close the intake unit 10, in the intake unit 10 of this embodiment, while opening from a closed state to a certain extent, air will surely flow into the active intake grille from between the plurality of blades 6. At the same time, since the first end of the blade 6 moves far away from the edge of the intake unit mounting port with respect to the second end of the blade 6, when air enters the active intake grille in this embodiment, it will not deviate greatly from the traveling direction like the active intake grille using the conventional straight waterfall blade B.

[0036] To explain this in more detail, as shown in FIG. 44, due to regulations, the exposed grille cannot open outward, that is, it cannot be reversed toward the outside of the vehicle. Therefore, the straight waterfall blade B can only be reversed in one direction, that is, toward the inside of the vehicle, and further open the intake port. In other words, the straight waterfall blade B can only open unidirectionally. Based on the design that the straight waterfall blade B can only open unidirectionally, obviously, under the opening angle of most of the straight waterfall blades B, during the opening process of the straight waterfall blade B, among the air entering the vehicle from the outside through the intake port into the vehicle, the traveling direction of a considerable part of the air deviates from the traveling direction. Needless to say, this has an adverse effect on the effective intake area of the grille and thus affects the heat dissipation efficiency. In response to this, as described above, such a situation does not occur in the intake grille of the present invention. Based on this, the active intake grille according to this embodiment has the advantages of a large effective intake area and can improve the heat dissipation efficiency.

[0037] Next, a more detailed exemplary installation method of the aforementioned active intake grille is shown.

[0038] As shown in FIGS. 1 and 2, the fixed bracket 1 is provided with six hexagonal intake unit attachment ports in sequence, and the six hexagonal intake units 10 are attached to these six intake unit attachment ports in a one-to-one correspondence, and each intake unit 10 is provided with six triangular blades 6. For the convenience of illustration, the three intake units 10 located on the right side of the actual vehicle are provided in a closed state, and the three intake units 10 located on the left side of the actual vehicle are arranged so as to be inverted at a certain angle rearward of the vehicle with respect to the fixed bracket 1, that is, these three intake units 10 are in an open state.

[0039] Exemplarily, the fixed bracket 1 includes an outer frame 1a and an inner frame 1b arranged in sequence from the front of the vehicle to the rear of the vehicle. Here, the outer frame 1a is located on the front side of the linkage bracket 2, and six hexagonal through-holes for forming the aforementioned intake unit attachment ports are respectively provided in the outer frame 1a and the inner frame 1b. At the same time, in order to ensure the overall strength of the intake unit attachment port, a radial support frame 23 is provided horizontally across each through-hole provided in the outer frame 1a.

[0040] Continue to refer to FIGS. 1 and 2. The active intake grille is provided with an interlocking bracket 2 of two substantially rectangular frames. One of the two interlocking brackets 2 is located at the rear side of the three intake units 10 on the left part of the actual vehicle, and the other is located at the rear side of the three intake units 10 on the right part of the actual vehicle. Exemplarily, when the intake unit 10 is in the open state, the intake passage is configured to be formed in the active intake grille between the blades 6 of the same intake unit 10. The intake passage α continues to expand according to the opening degree in which the blade 6 reverses toward the vehicle interior until the blade 6 turns to the maximum opening degree. The intake passage α is arranged so that air can enter the active intake grille through it. When the intake unit 10 is in the closed state, the intake passage α disappears. Each blade 6 within the same intake unit 10 is arranged such that when the interlocking bracket 2 moves in the direction away from the intake unit mounting port, the intake unit 10 opens and the intake passage α is formed between the blades 6. After the formation of the intake passage α, the interlocking bracket 2 returns in the direction approaching the intake unit mounting port, and the intake passage α disappears. That is, in the process of the interlocking bracket 2 moving in the direction approaching the intake unit mounting port, the intake passage α gradually shrinks and disappears when the reset of the blade 6 is completed. The direction away from the aforementioned intake unit mounting port is generally from front to back. The direction approaching the aforementioned intake unit mounting port is generally from back to front.

[0041] Exemplarily, the interlocking bracket 2 is further provided with a fitting port 2a that corresponds one-to-one to the intake unit 10. The fitting port 2a is arranged to penetrate the interlocking bracket 2 and communicate with the intake passage α. Thereby, when the intake unit 10 is open, there is no solid part on the rear side of the intake passage α in the interlocking bracket 2 that directly obstructs the entry of air. At the same time, there is no solid body exposed through the intake passage α in the interlocking bracket 2, ensuring the aesthetic appearance of the vehicle.

[0042] Also, based on the above structure, a preferred but not necessarily adopted solution includes fixing magnetic parts that can attract each other to the inner frame 1b and the linkage bracket 2 respectively. The beneficial effect of such an installation is that when the active intake grille is used for a long time, some fitting deviations occur between the internal parts, and even if the linkage bracket 2 cannot be simply driven by the driving device 3 to move to a predetermined position, since the above-mentioned mutually attractable magnetic parts are provided, the inner frame 1b and the linkage bracket 2 can be fitted to a predetermined position by the magnetic attraction force of the magnetic parts, and the blade 6 will not fail to close.

[0043] Continuing to refer to FIGS. 3 and 4. To move the linkage bracket 2 to move the blade 6 relative to the fixed bracket 1, the driving device 3 needs to drive the first linkage mechanism 4 to move the linkage bracket 2. Based on this, illustratively, the intake grille further includes a drive shaft 41 fixedly connected to the driving device 3. One end of the drive shaft 41 is fixedly connected to the driving device 3, and the other end of the drive shaft 41 is rotatably connected to the first linkage mechanism 4. At the same time, the shape of the inner frame 1b approximates a long U-shaped part with an opening facing the rear of the vehicle. The linkage bracket 2 corresponds to moving at the opening part of this U-shaped inner frame 1b during movement. The driving device 3 is located below the inner frame 1b, and the first linkage mechanism 4 is located below the linkage bracket 2 and is at the same time between the inner frame 1b and the linkage bracket 2, that is, it is not only connected to the inner frame 1b but also connected to the linkage bracket 2. In this embodiment, when the driving device 3 is operated and the drive shaft 41 is rotated, the first linkage mechanism 4 can move the linkage bracket 2 back and forth relative to the fixed bracket 1.

[0044] Continuing to refer to FIGS. 4 and 5, the first link mechanism 4 also illustratively includes a connected main shaft 42 and a plurality of sub - arms 43. One end of each arm 43 is rotatably connected to the main shaft 42, another sub - arm 43, or the drive shaft 41 in the orientations shown in FIGS. 6 and 7. The first link mechanism 4 has one arm 43 sharing a rotation axis with the drive shaft 41. The drive device 3 rotates the drive shaft 41, and the drive shaft 41 moves and rotates the sub - arm 43 sharing the rotation axis with it, and further moves the other sub - arms 43 and the main shaft 42, and is arranged to form the movement of the first link mechanism 4. Illustratively, when the drive shaft 41 moves in the clockwise direction in FIG. 8, the other sub - arms 43 also move along the corresponding directions shown in FIG. 8 (for example, the sub - arm 43 in part I moves to one side while rotating counterclockwise in FIG. 8), and the first link mechanism 4 moves the interlocking bracket 2 to move it from front to back, shifting the intake unit 10 from the closed state to the open state. Similarly, when the drive device 3 drives the drive shaft 41 to move in the counterclockwise direction in FIG. 8, the interlocking bracket 2 can be moved back from back to front to close the intake unit 10 again. In possible embodiments, the drive shaft 41 may be an assembly with the drive device 3, may be an assembly with the first link mechanism 4, or may be an independent individual component independent of the first link mechanism 4 and the drive device 3.

[0045] Continuing to refer to FIG. 9, to clearly show the movement of each part of the first link mechanism 4, FIG. 9 shows the first link mechanism 4 located on the left part of the vehicle in this embodiment and another first link mechanism 4 located on the right part of the vehicle in this embodiment. Here, the three corresponding intake units 10 of the former are all in the open state, and the corresponding blades 6 have an opening degree that reverses into the vehicle interior. The three corresponding intake units 10 of the latter are all in the closed state, and the corresponding blades 6 do not have an opening degree that reverses into the vehicle interior.

[0046] By way of example, the first link mechanism 4 is also rotatably connected to the inner frame 1b and has four connection points 9 as shown in FIG. 10 (filled in for easy illustration of these four connection points 9). The first link mechanism 4 is also rotatably connected to the interlocking bracket 2 and has five connection points 9 as shown in FIGS. 11 and 12 (filled in for easy illustration of these five connection points 9). Also, regarding the specific connection methods between the sub-arms 43 in the first link mechanism 4, between the sub-arm 43 and the main shaft 42, and between the sub-arm 43 and the drive shaft 41, those skilled in the art can flexibly install them as needed, clearly knowing that the interlocking bracket 2 needs to move back and forth. For those skilled in the art, disclosing the specific form of the first link mechanism 4 is sufficient for implementing this structure on the premise that those skilled in the art conduct limited tests.

[0047] Similarly, it can be easily understood that the first link mechanism 4 can not only adopt the above-mentioned structure, but those skilled in the art can also adjust and redesign the specific form of the first link mechanism 4. For example, the first link mechanism 4 may be in the form shown in FIG. 13 and may also have a motion schematic diagram and a predicted motion stroke as shown in FIG. 14. The first link mechanism 4 may be in the form shown in FIG. 15 and may also have a motion schematic diagram and a predicted motion stroke as shown in FIG. 16.

[0048] In particular, by applying any one of all the first link mechanisms 4 described above, or a similar flat link structure, between the interlocking bracket 2 and the fixed bracket 1, the drive device 3 can be arranged below the interlocking bracket 2 and the fixed bracket 1, eliminating the need to arrange the drive device 3 behind the interlocking bracket 2 and the fixed bracket 1, saving the in-vehicle arrangement space and facilitating the designer to arrange the components that need to be cooled (e.g., the engine) located behind the active intake grille. Furthermore, from the perspective of structural design, the length of the first link mechanism 4 can be relatively easily matched according to the length in the left-right direction of the actual vehicle of the interlocking bracket 2 and the fixed bracket 1. Additionally, sufficient connection points 9 are arranged between the first link mechanism 4 and the interlocking bracket 2 and between the first link mechanism 4 and the fixed bracket 1, ultimately providing a sufficient connection strength to the structure formed by the first link mechanism 4, the interlocking bracket 2, and the fixed bracket 1, ensuring that the interlocking bracket 2 can smoothly move the aforementioned blade link mechanism 7, and further ensuring that the blade 6 is reversed and the intake unit 10 is opened and closed.

[0049] Refer to FIG. 17. FIG. 17 is a comparative schematic diagram of the closed intake unit 10 and the open intake unit 10. From FIG. 17, it can be seen that the intake unit 10 includes a plurality of blades 6 and a plurality of blade link mechanisms 7 as described above. Based on this, illustratively, the blade link mechanism 7 is rotatably connected to the blade 6 and also engages with the blade 6. The blade link mechanism 7 is rotatably connected to the interlocking bracket 2 and also engages with the interlocking bracket 2.

[0050] Continuing to refer to FIGS. 18 and 19. Exemplarily, each blade 6 is rotatably connected to the fixed bracket 1 by a single rotation axis 8. Exemplarily, the blade link mechanism 7 includes a main body 71 and a first engaging portion 72. A first base region 711 is provided on the main body 71. The first base region 711 and the first engaging portion 72 are connected. The first engaging portion 72 is provided on the first base region 711. The first engaging portion 72 includes a first shaft portion 721 and an engaging portion group 722 provided in order from proximal to distal from the main body 71. The engaging portion group 722 includes a first engaging portion 7221 and a second engaging portion 7222. The first engaging portion 7221 and the second engaging portion 7222 are provided at an interval, and are respectively connected to the first shaft portion 721 and are elastically deformable. Correspondingly, a second engaging portion 61 is provided on the blade 6. The engaging portion group 722 engages with the second engaging portion 61, and the first shaft portion 721 is rotatably connected to the second engaging portion 61. The second engaging portion 61 is located between the engaging portion group 722 and the main body 71. The engaging portion group 722 and the first base region 711 are arranged to cooperate to limit at least a part of the second engaging portion 61 therebetween, and thus to limit the detachment of the blade link mechanism 7 and the blade 6.

[0051] Subsequent to the above-described content, regarding the installation of the blade link mechanism 7, as a scheme that is preferable but not necessarily adopted, the main body 71 is integrally formed with the first engaging portion 72. The first shaft portion 721 and the engaging portion group 722 are located on the same side of the main body 71. The first shaft portion 721 is formed to extend from the main body 71 to the outside of the main body 71. The first engaging portion 7221 and the second engaging portion 7222 are formed to extend from the first shaft portion 721 to the outside of the first shaft portion 721. And the first engaging portion 7221 and the second engaging portion 7222 each include a joint for forming an engaging relationship with the second engaging portion 61. The main body 71 and the joint cooperate to limit at least a part of the second engaging portion 61 therebetween, and further limit the detachment of the blade link mechanism 7 and the blade 6.

[0052] As another preferred but not necessarily adopted scheme for the above structure, the first shaft portion 721 is a columnar body with a non-uniform diameter, the second engaging portion 61 is substantially sleeve-shaped (see FIG. 20), and the maximum diameter of the first shaft portion 721 is such that a part of the first shaft portion 721 abuts against the inner wall of the second engaging portion 61 and is arranged so as not to inhibit the rotation of the first shaft portion 721.

[0053] As another preferred but not necessarily adopted scheme for the above structure, the first shaft portion 721 is rotatably connected to the second engaging portion 61 at the centroid of the blade 6. By arranging it in this way, it is possible to ensure that the force received by the blade 6 is stable, and the force required for the blade 6 to reverse (supplied by the driving device 3) does not become excessive.

[0054] Exemplarily, the blade link mechanism 7 further includes a third engaging portion 73, the main body 71 is further provided with a second base region 712, the second base region 712 is connected to the third engaging portion 73, and the third engaging portion 73 is provided in the second base region 712. The third engaging portion 73 includes a second shaft portion 731 (for the convenience of illustration, one second shaft portion 731 is filled). At the same time, the interlocking bracket 2 is provided with a fourth engaging portion 2b (see FIG. 21), and the second shaft portion 731 is rotatably connected to the fourth engaging portion 2b. Based on this configuration, as a preferred but not necessarily adopted scheme, the main body 71 and the third engaging portion 73 are integrally formed, and the second shaft portion 731 extends from the main body 71 to the outside of the main body 71.

[0055] Continuing to refer to FIG. 22, in order to enhance the connection stability between the blade link mechanism 7 and the fixed bracket 1, the third engaging portion 73 further includes a third engaging portion 732. The third engaging portion 732 is provided at a distance from the second shaft portion 731 and engages with the aforementioned fourth engaging portion 2b. As a preferable but not necessarily required installation of the third engaging portion 732, the third engaging portion 732 and the second shaft portion 731 are located on the same side of the main body 71, the third engaging portion 732 extends from the main body 71 to the outside of the main body 71 and includes a joint for forming an engaging relationship with the fourth engaging portion 2b, and the main body 71 and the joint cooperate with each other to limit at least a part of the fourth engaging portion 2b therebetween, and further includes restricting the detachment between the blade link mechanism 7 and the fixed bracket 1.

[0056] When the blade link mechanism 7 is provided with an engaging portion group 722 and the third engaging portion 732 is provided, it corresponds to the two ends of the blade link mechanism 7 being respectively engaged with the blade 6 and the linkage bracket 2. By designing in this way, reliable connection stability is provided between the blade link mechanism 7 and the blade 6 and the linkage bracket 2, and it can be ensured that the blade link mechanism 7 does not detach from the blade 6 and the linkage bracket 2 in various driving situations (for example, when driving and swaying).

[0057] Regarding the above structure, there are other preferable proposals, but they are not necessarily required to be adopted, as follows. As described above, when the engaging part group and the main body 71 limit at least a part of the second engaging part 61 therebetween, and the third engaging part 732 and the main body 71 limit at least a part of the fourth engaging part 2b therebetween, the margin for the second engaging part 61 to pivot between the engaging part group and the main body 71 is regarded as the first margin, and the margin for the fourth engaging part 2b to pivot between the third engaging part 732 and the main body 71 is regarded as the second margin. Preferably, the second margin is larger than the first margin. The reason for installing in this way is to leave an appropriate pivotable space in the three-component assembly chain of the blade 6 - blade link mechanism 7 - interlocking bracket 2 on the premise of ensuring that the blade link mechanism 7 does not escape. Thereby, when the vehicle sways, when the force due to pitching is transmitted to the three of the blade 6 - blade link mechanism 7 - interlocking bracket 2, the above-mentioned force causes the fourth engaging part 2b to slip between the third engaging part 732 and the main body 71, and is consumed during this slipping, and unnecessary mutual movement or collision between other closely assembled parts in the active intake grille does not occur, and no stress is generated.

[0058] Regarding the above structure, as another preferable but not necessarily required measure, the positions of the first engaging part 72 and the third engaging part 73 on the main body 71 can be swapped with each other, and correspondingly, the characteristic forms of the second engaging part 61 on the blade 6 and the fourth engaging part 2b on the interlocking bracket 2 may also be swapped.

[0059] Continuing to refer to FIGS. 18 and 19. Exemplarily, the blade link mechanism 7 includes an elastic part 74 (for the convenience of illustration, one elastic part 74 is filled in). The elastic part 74 is used to be connected to the main body 71 and abut against the interlocking bracket 2 so as to play a buffering role when the blade link mechanism 7 and the interlocking bracket 2 move relatively.

[0060] Refer to FIG. 23. For the above-described structure, another scheme that is preferable but not necessarily adopted is that at least one through region 741 is provided in the elastic portion 74, and the through region 741 is used to facilitate the deformation of a part of the elastic portion 74 close to the edge of the elastic portion 74 located on its circumferential side. As shown in FIGS. 24 and 25, another scheme that is preferable but not necessarily adopted is that the number of installed through regions 741 is two or more, and different through regions 741 are used to facilitate the deformation of different positions of the elastic portion 74, and different positions of this elastic portion 74 include that the blade link mechanism 7 and the interlocking bracket 2 play a buffering role at different timings when moving. Another scheme that is preferable but not necessarily adopted includes that the through region 741 is polygonal or circular, and the elastic portion 74 is integrally formed with the main body 71 by insert molding.

[0061] It should be further explained that, as is clear from the above, the blade link mechanism 7 actually corresponds to a rotation adapter, that is, this embodiment further provides an adapter for rotation. If one of the second member and the first member is the blade 6 and the other is the interlocking bracket 2, the design principle of this adapter is as follows.

[0062] A rotation adapter that connects the first member and the second member at different positions, and includes a main body 71 and a third engaging portion 73 connected to the main body 71. A second base region 712 is provided in the main body 71, and the third engaging portion 73 is provided in the second base region 712. The third engaging portion 73 includes a second shaft portion 731 and a third engaging portion 732 provided at intervals. A fourth engaging portion 2b is provided on the aforementioned second member. The second shaft portion 731 is for rotatably connecting with the fourth engaging portion 2b. The aforementioned third engaging portion 732 is for connecting with the fourth engaging portion 2b. And the main body 71 and the third engaging portion 732 cooperate with each other to limit at least a part of the fourth engaging portion 2b therebetween, further limit the movement of the fourth engaging portion 2b, and are used to limit the detachment of the adapter and the second part.

[0063] Based on the above structure, it is also necessary to describe some of the backgrounds of the adapter settings in the following related technologies.

[0064] In related technologies, transmission between components often requires the use of an adapter. When one of the two components is the first component and the other is the second component, the adapter needs to be connected to the first component and the second component at different positions respectively. Moreover, in order to prevent the adapter from detaching from the component, in the structure formed by the adapter and the component, it is necessary to design a corresponding stopper structure such as a fastening component like the fastening part C. Based on this, the connection structure between some adapters and components includes the fastening part C provided with two intervals shown in Fig. 45 and an engaging hole D. Here, the two fastening parts C are integrally formed on the solid part E which is one of the adapter and the component and is elastically deformable. When it is necessary to assemble the adapter and the component, by applying force to the two fastening parts C to temporarily bring them closer to each other, and then putting them into the engaging hole D and then removing the external force, the fastening of the adapter and the corresponding component can be completed. At this time, the solid part E and the fastening part C cooperate with each other to prevent the adapter and this member from detaching from each other along the direction parallel to the center line of the engaging hole D.

[0065] Subsequent to the above content, in the transmission structure by the adapter between the first member and the second member, there may be a case where the connection points between the first member and the adapter and between the second member and the adapter are provided to form a fastening relationship using two fastening parts C. The drawback of such a scheme is that it is necessary to provide two pairs, that is, a total of four fastening parts C at one time, and at least one of the problems such as the high production cost of the fitting structure of the adapter and the component, the high production accuracy, and the high assembly difficulty (it is necessary to apply force to the fastening parts C at different connection points simultaneously during assembly) is likely to occur.

[0066] Correspondingly, for the provided rotation adapter, first, since only the third engaging part C is provided at one end of the rotating part, through the fitting of the third engaging part C and the main body 71, the adapter is connected to and engaged with the second member. Compared with the related art where four engaging parts C are provided, it has the advantage of low production cost. Next, since the third engaging part C and the second shaft part 731 are provided at an interval, the production requirement accuracy of this adapter is also low. Finally, with only the third engaging part C provided at one end of the rotating part, through the engagement of the third engaging part C and the main body 71, the adapter is connected to the second member and realizes the engagement with the second member. Therefore, for the assembly of the location end of the third engaging part C, it is not necessary for the worker to bias a pair of engaging parts C belonging to different ends simultaneously, and the assembly difficulty of this adapter is also low.

[0067] Note that since one of the second member and the first member is the blade 6 and the other is the linkage bracket 2, all the settings related to the aforementioned blade 6, linkage bracket 2, and blade linkage mechanism 7 can be correspondingly applied to the second member, the first member, and the adapter in a one-to-one manner.

[0068] Based on this, this embodiment actually provides a kind of push-pull structure. The design principle of this push-pull structure is as follows. The push-pull structure includes the first member, the second member, and the aforementioned adapter. The adapter is rotatably connected to the first member and the second member at different positions respectively, and at the same time, is engaged with the first member and the second member. The first member and the second member can be transmitted through the adapter.

[0069] Continue to refer to FIG. 25. Exemplarily, the active intake grille further includes a second link mechanism 5. Corresponding to the installation located below the linkage bracket 2 of the first link mechanism 4, the second link mechanism 5 is respectively connected to the upper end of the fixed bracket 1 on the actual vehicle, the lower end of the fixed bracket 1 on the actual vehicle, the upper end of the linkage bracket 2 on the actual vehicle, and the lower end of the linkage bracket 2 on the actual vehicle. When the first link mechanism 4 moves the linkage bracket 2 relative to the fixed bracket 1, the second link mechanism 5 moves adaptively.

[0070] At the same time, the second link mechanism 5 has at least two connection points with the interlocking bracket 2. These at least two connection points are respectively located at two opposite ends of the interlocking bracket 2. The second link mechanism 5 has at least two connection points with the fixed bracket 1. These at least two connection points are respectively located at two opposite ends of the fixed bracket 1.

[0071] Subsequent to the above-described content, the second link mechanism 5 transmits the force transmitted by the first link mechanism 4 to the connection point between the first link mechanism 4 and the interlocking bracket 2 to the entire interlocking bracket 2, ensuring that the opening and closing operation of the intake unit 10 works well in any operating situation, and is used to ensure the structural strength and modality of the system formed among the blade 6, the interlocking bracket 2, and the fixed bracket 1.

[0072] To explain this in more detail, since the first link mechanism 4 is provided below the interlocking bracket 2 and is located between the interlocking bracket 2 and the fixed bracket 1, the first link mechanism 4 is provided at the lower part of the active intake grille and corresponds to moving the interlocking bracket 2 by "push-pull". Based on this, first, when the vehicle is traveling on a highway and needs to resist strong wind force, etc., the active intake grille equipped with the second link mechanism 5 can quickly transmit the force applied by the first link mechanism 4 to the lower part of the interlocking bracket 2 to the entire interlocking bracket 2, ensuring that the blade 6 smoothly completes the necessary reverse movement under strong wind force and opens and closes the intake unit 10. Next, since the second link mechanism 5 is connected to the upper and lower ends of the interlocking bracket 2 and is also connected to the upper and lower ends of the fixed bracket 1, it can transmit force to the system of the blade 6 - the interlocking bracket 2 - the fixed bracket 1, which corresponds to the existence of a firm movable bridge. This will undoubtedly increase the structural strength and modality of the entire system while increasing the structural strength and modality of the entire active intake grille.

[0073] Continuing to refer to FIG. 26, by way of example, the second link mechanism 5 includes a first divided body 51 and a second divided body 52 that are rotatably connected. One of the first divided body 51 and the second divided body 52 is rotatably connected to the fixed bracket 1, and the other of the first divided body 51 and the second divided body 52 is rotatably connected to the interlocking bracket 2. Further, although not necessarily required, a preferred arrangement includes providing a shaft region 53 on one of the first divided body 51 and the second divided body 52, providing a rotary connection portion 54 on the other, and the rotary connection portion 54 being rotatably connected to the shaft region 53. FIG. 26 schematically shows the case where the shaft region 53 is provided on the first divided body 51 and the rotary connection portion 54 is provided on the second divided body 52.

[0074] As a preferred but not necessarily required arrangement, the rotary connection portion 54 is a sleeve with an open side surface integrally formed on one of the first divided body 51 and the second divided body 52, and the shaft region 5 is a cylinder integrally formed on the other of the first divided body 51 and the second divided body 52. In FIG. 26, the configuration where the shaft region 53 is provided on the first divided body 51 and the rotary connection portion 54 is provided on the second divided body 52 is adopted.

[0075] As a preferred but not necessarily required arrangement, both the first divided body 51 and the second divided body 52 are U-shaped. The U-shaped first divided body 51 is rotatably connected to one of the interlocking bracket 2 and the fixed bracket 1 at one end of its opening position, and rotatably connected to the other of the interlocking bracket 2 and the fixed bracket 1 at the other end of its opening position.

[0076] As a preferred but not necessarily required arrangement, in the active intake grille, as shown in FIG. 2, the second link mechanism 5 is connected to the upper left and lower left corners of the vehicle body of the interlocking bracket 2, and is also connected to the upper left and lower left corners of the vehicle body of the fixed bracket 1. Further, the second link mechanism 5 is connected to the upper right and lower right corners of the vehicle body of the interlocking bracket 2, and is also connected to the upper right and lower right corners of the vehicle body of the fixed bracket 1.

[0077] Continuing to refer to FIG. 27, as an installation that is preferable but not necessarily required, the second divided body 52 further includes a component force portion 55 that protrudes upward with respect to the circumferential side.

[0078] As shown in FIG. 25, the purpose of installing this component force portion 55 is to share the force received by the blade 6 during the opening and closing of the intake unit 10. To explain this in more detail, in some possible embodiments, when the blade 6 flips outside the vehicle until it closes the intake unit 10 from inside the vehicle, it may contact the support frame 23 in the exterior frame 1a. The judgment condition (i.e., operation logic) for the drive device 3 to stop moving and advancing the interlocking bracket 2 is that when the drive device 3 encounters a certain resistance, it stops moving and advancing the interlocking bracket 2. Here, the aforementioned "certain resistance" means that when the blade 6 flips until it closes the intake unit 10, the blade 6 is obstructed by the support frame 23 in the exterior frame 1a, and a reaction force of a certain value is generated between the blade 6 and the support frame 23.

[0079] In other words, under the said judgment logic, it is desired that the judgment condition for the drive device 3 to stop moving and advancing the interlocking bracket 2 be satisfied. In fact, it is necessary that the blade 6 first collides with the support frame 23 under the drive of the drive device 3, and the force with which the blade 6 collides with the support frame 23 is transmitted to the drive device 3 as resistance.

[0080] Based on this, a force-dividing part 55 is provided, and when the blade 6 and the support frame 23 collide, the first divided body 51 is arranged to collide with the force-dividing part 55 simultaneously. Thus, the force generated when the first divided body 51 collides with the force-dividing part 55 is also fed back to the driving device 3 in the form of resistance, and the resistance received by the driving device 3 actually changes to the resultant force formed by the force between the first divided body 51 and the force-dividing part 55 and the force between the blade 6 and the support frame 23. This resultant force can easily satisfy the determination condition of the driving device 3, and the driving device 3 can be made to immediately stop the forward movement of the linkage bracket 2. Based on this, since there is a force between the first divided body 51 and the force-dividing part 55 that shares the numerical value, during the process of the blade 6 and the support frame 23 colliding, the force that the blade 6 should receive naturally decreases. With such a design, the probability that the blade 6 is deformed in appearance (for example, dents are formed on the surface due to excessive collision with the support frame 23) during the long-term use of the active intake grille can be reduced.

[0081] In addition, if it is designed to block the blade 6 and give the driving device 3 a resistance that satisfies the determination condition, instead of the method of making the blade 6 and the support frame 23 collide as described above, another stopper feature may be provided on the rotation locus of the blade 6 in the fixed bracket 1.

[0082] Note that the second link mechanism 5 can not only adopt the above configuration, but those skilled in the art can adjust and redesign the specific form of the second link mechanism 5. For example, the second link mechanism 5 may be in the form shown in FIG. 28, and has a motion schematic diagram and an expected motion stroke as shown in FIG. 29. Points [1] and [2] in FIG. 29 respectively indicate the connections between the second link mechanism 5 and the upper and lower ends of the interlocking bracket 2 on the actual vehicle. The second link mechanism 5 may be in the form shown in FIG. 30, and has a motion schematic diagram and an expected motion stroke as shown in FIG. 31. Points [3] and [4] in FIG. 31 respectively indicate the connections between the second link mechanism 5 and the upper and lower ends of the interlocking bracket 2 on the actual vehicle. The second link mechanism 5 may be in the form shown in FIG. 32, and has a motion schematic diagram and an expected motion stroke as shown in FIG. 33. Points [5] and [6] in FIG. 33 respectively indicate the connections between the second link mechanism 5 and the upper and lower ends of the interlocking bracket 2 on the actual vehicle.

[0083] Based on the above configuration, this embodiment actually further provides a kind of moving structure with the interlocking bracket 2 as the moving required member and the fixed bracket 1 as the position fixing member. Regarding the installation principle of this moving structure, it includes the moving required member, the position fixing member, the first link mechanism 4 and the second link mechanism 5. The position of the position fixing member is fixed, the first link mechanism 4 is located on one side of the moving required member, and is respectively connected to the moving required member and the position fixing member at different positions thereof. The second link mechanism 5 is respectively connected to the moving required member and the position fixing member at different positions thereof. The first link mechanism 4 can move the moving required member by an external force to move it relative to the position fixing member, and can adaptively move the second link mechanism 5.

[0084] There are at least two connection points between the second link mechanism 5 and the member in need of movement. At least two connection points of the second link mechanism 5 are respectively located at two opposite ends of the member in need of movement. There are at least two connection points between the second link mechanism 5 and the position-fixed member. At least two connection points of the second link mechanism 5 are respectively located at two opposite ends of the position-fixed member. The second link mechanism 5 is used to transmit the force transmitted from the first link mechanism 4 to the connection part with the member in need of movement to the whole of the member in need of movement.

[0085] The second link mechanism 5 includes a first divided body 51 and a second divided body 52 that are rotatably connected. One of the first divided body 51 and the second divided body 52 is rotatably connected to the fixed bracket 1, and the other of the first divided body 51 and the second divided body 52 is rotatably connected to the interlocking bracket 2. An axial region 53 is provided on one of the first divided body 51 and the second divided body 52, and a rotary connection part 54 is provided on the other. The rotary connection part 54 is rotatably connected to the axial region 53.

[0086] Since the position-fixed member is the fixed bracket 1 and the member in need of movement is the interlocking bracket 2, all of the above installations of the fixed bracket 1 and the interlocking bracket 2 can be correspondingly applied one-to-one to the position-fixed member and the member in need of movement.

[0087] Based on the above configuration, it is also necessary to explain some backgrounds for providing a moving structure in the related art. In the related art, it is necessary to reciprocate a member in need of movement along a certain predicted trajectory with respect to a certain fixed position-fixed member. For example, if it is necessary to move the member in need of movement back and forth with respect to the position-fixed member, common design plans include the following. As shown in FIG. 46, the side surface of this member in need of movement is connected to a motor assembly G with a telescopic rod F for the driving device. On the premise that the telescopic rod F is parallel in the front-back direction, this member in need of movement is driven by the motor assembly G to realize a reciprocating motion.

[0088] Regarding the drawbacks of such a design, when the contact position between the motor assembly G and the moving demand member is not at the center of gravity of the moving demand member, and the volume of the aforementioned moving demand member is much larger than the contact area between the telescopic rod F and the moving demand member, the moving demand member is equivalent to receiving pushing at only one point. Since the moving demand member is pushed at only one point, when the moving demand member also receives other external forces (for example, it is necessary to resist strong wind force), the motion stability of the moving demand member is likely to decrease.

[0089] Correspondingly, in the aforementioned moving structure, there is a second link mechanism 5. The second link mechanism 5 forms a rapid force transmission bridge-like existence between the moving demand member and the position fixing member, and the connection between itself and the moving demand member and the position fixing member can strengthen the structural strength and modality of the entire moving structure. Therefore, the moving structure provided in this embodiment has good motion stability with respect to the related art. Similarly, the moving demand member therein also has good motion stability.

[0090] <Example 2> This application provides an active intake grille. As shown in FIGS. 34 to 43, FIG. 13, FIG. 15, FIG. 28, FIG. 30, and FIG. 32, this active intake grille includes a fixed bracket 1, an interlocking bracket 2, a driving device 3, a first link mechanism 4, and at least one intake unit 10. The intake unit 10 includes a plurality of blades 6 and a plurality of blade link mechanisms 7. The interlocking bracket 2 is rotatably connected to the first end of each blade link mechanism 7 among the plurality of blade link mechanisms 7, and the second end of each blade link mechanism 7 is rotatably connected to the first end of each blade 6 in a one-to-one manner. The second end of the blade 6 is rotatably connected to the fixed bracket 1, the first end of the first link mechanism 4 is connected to the interlocking bracket 2, and the second end of the first link mechanism 4 is connected to the driving device 3. When the driving device 3 drives the first link mechanism 4 to move, the first link mechanism 4 moves the interlocking bracket 2, the interlocking bracket 2 moves the blade link mechanism 7, and the blade link mechanism 7 rotates the first end of the blade 6 to open and close the intake unit 10.

[0091] In the present application, the driving device 3 is connected to the first link mechanism 4. Under the driving action of the driving device 3, the driving shaft 41 of the first link mechanism 4 moves to drive the first link mechanism 4 to move. Since one end of the first link mechanism 4 is fixedly connected to the interlocking bracket 2, in the process of the first link mechanism 4 moving, the first link mechanism 4 moves the interlocking bracket 2 and moves it along the thickness direction of the interlocking bracket 2. The interlocking bracket 2 is rotatably connected to the first end of the blade link mechanism 7, the second end of the blade link mechanism 7 is rotatably connected to the blade 6, and the blade 6 is rotatably connected to the fixed bracket 1. Therefore, in the process of the interlocking bracket 2 moving along the thickness direction of the interlocking bracket 2, the interlocking bracket 2 rotates the blade 6 through the blade link mechanism 7. When the blade 6 rotates, the intake unit 10 opens to achieve the intake effect. When the opening angles of the blades are the same, compared with the conventional active intake grille, the effective intake area of the active intake grille of the present application is significantly increased, improving the heat dissipation efficiency. Also, in the present application, a plurality of blades are installed. Under the same blade area, the wind force is shared among the plurality of blades to increase the overall endurance of the intake unit 10 and make it less likely to break. In the present application, by connecting a plurality of sets of blades to the interlocking bracket, the synchronism of the movement of each blade is ensured in the process of the interlocking bracket moving along the thickness direction of the interlocking bracket.

[0092] In some embodiments, one end of the first link mechanism 4 is fixedly connected to the fixed bracket 1. By fixedly connecting the first link mechanism 4 to the fixed bracket 1, when the first link mechanism 4 moves the interlocking bracket 2 and moves it towards the second end of the blade 6 or moves it away from the second end of the blade 6, the stability of the movement of the interlocking bracket 2 is enhanced.

[0093] In some embodiments, a second link mechanism 5 is further provided. One end of the second link mechanism 5 is fixedly connected to the fixed bracket 1, and the other end of the second link mechanism 5 is fixedly connected to the interlocking bracket 2. It should be noted that the first link mechanism 4 may be provided in the longitudinal direction of the active intake grille. That is, after the active intake grille is attached to the vehicle, the first link mechanism 4 may be provided at the bottom of the active intake grille. The second link mechanism 5 may be provided in the width direction of the active intake grille. That is, after the active intake grille is attached to the vehicle, the first link mechanism 4 may be provided on the side of the active intake grille. In the present application, the first link mechanism 4 and the second link mechanism 5 are installed, the second link mechanism 5 is driven through the first link mechanism 4, and the first link mechanism 4 and the second link mechanism 5 jointly drive the interlocking bracket 2 to move, thereby ensuring the balance, synchronism and simultaneity of the movement of the interlocking bracket 2 during movement, and further improving the angle synchronism and angle stability when a plurality of blades rotate.

[0094] In some embodiments, the active intake grille includes a first intake portion 11 and a second intake portion 12. The first intake portion 11 and the second intake portion 12 are respectively provided with a drive device 3, a first link mechanism 4 and at least one intake unit 10. The drive device 3 is electrically connected to the controller of the vehicle. The controller is used to individually control a single drive device 3. In the present application, the entire active intake grille is divided into at least a first intake portion 11 and a second intake portion 12, and the movement directions of the blades of the first intake portion 11 and the second intake portion 12 can be individually controlled by independent drive motors. The movement directions and rotation angles of the blades of both may or may not be made to coincide. The opening angles of the blades in the intake units 10 of the first intake portion 11 and the second intake portion 12 can be set as required, and the applicability is wide. Preferably, the second link mechanism 5 is respectively provided in the first intake portion 11 and the second intake portion 12.

[0095] In some embodiments, when the intake unit 10 is in the open state, at least two blades 6 are not parallel to each other so that the orientations of at least two blades 6 do not coincide. Thereby, when the intake unit 10 is in the open state, intake at a plurality of angles of the intake unit 10 is realized.

[0096] In some embodiments, the second end of the blade link mechanism 7 is pivotally connected to the free end of the blade 6, and the connection end of the blade 6 is pivotally connected to the fixed bracket 1. A single blade 6 is pivotally connected to at least one blade link mechanism 7. The number of the blade link mechanisms 7 can be set as required, and is not limited herein.

[0097] In some embodiments, as shown in FIGS. 36 to 39, a rotating shaft is provided at the connection location between the blade 6 and the fixed bracket 1, and the blade 6 can move away from the fixed bracket 1 along the rotating shaft. The rotation directions of the plurality of blades 6 in a single intake unit 10 are different from each other. The present application saves more internal space compared with single-opening or double-opening (i.e., opening from two directions). In addition, for an external intake grille, the regulations require that it cannot be opened outward. The axis of single-opening does not meet the regulatory requirements when it is in the middle. Also, when the axis opens inward from the side, a lot of internal space will be wasted. The multi-direction inward opening method of the present application can save internal space and meet the requirement of the intake air volume. On the other hand, the single-opening intake direction deviates from the driving direction, which has a certain impact on the stability of the vehicle body when the vehicle speed is high. The double-opening blades of the present application open symmetrically, the intake direction coincides with the driving direction, and does not affect the stability of the vehicle body. It should be noted that the rotating shaft can be a full shaft or a half shaft. Preferably, the rotating shaft is a full shaft, which improves the safety performance during the operation of the intake grille.

[0098] In some embodiments, the outer surface of the active intake grille has an arc structure. Since the outer surface of the active intake grille of the present application has an arc structure, the mobility within the arc surface of the active intake grille is realized. After the active intake grille is attached to the vehicle, the arc structure provides a large available space. A bumper with a multi-type structure can be placed in this space, and the applicable range is wide. Moreover, the appearance of the active intake grille of the present application is more aesthetically pleasing.

[0099] In some embodiments, refer to FIG. 43. FIG. 43 is a schematic diagram of the intake grille of the intake unit 10 with different shapes according to the embodiment of the present application. The shape of the blade 6 includes at least one of a triangle, a trapezoid, and a sector. Here, the trapezoid can include a straight trapezoid and an arc-bottom trapezoid. The shape of the intake unit 10 includes at least one of a circle and a polygon. Specifically, the blades are arranged annularly. Exemplarily, when the blade is triangular and three blades are installed in one intake unit 10, the shape formed by the three blades closing is triangular, that is, one intake unit 10 is triangular. Specifically, refer to FIG. 43(c). When the blade is triangular and four blades are provided in one intake unit 10, the shape formed by the four blades closing is square, that is, one intake unit 10 is quadrilateral. Specifically, refer to FIG. 43(d). When the blade is triangular and five blades are provided in one intake unit 10, the shape formed by the five blades closing is pentagonal, that is, one intake unit 10 is pentagonal. Specifically, refer to FIG. 43(a). When the blade is triangular and six blades are provided in one intake unit 10, the shape formed by the six blades closing is hexagonal, that is, one intake unit 10 is hexagonal. When the blade is sector-shaped and four blades are installed in one intake unit 10, the shape formed by the four blades closing is circular, that is, one intake unit 10 is circular. Specifically, refer to FIG. 43(b). It should be noted that the shape and structure of the linkage bracket can be adaptively modified according to the changes in the shape and structure of the blade.

[0100] In some embodiments, the fixed bracket is provided with an intake unit mounting port. The intake unit mounting ports are provided in a one-to-one correspondence with the intake units 10. The shape of the intake unit mounting port includes at least one of a circular shape and a polygonal shape. The plurality of blades are arranged circumferentially along the edge of the intake unit mounting port. A support frame 23 is provided inside the intake unit mounting port. Exemplarily, when the intake unit 10 is hexagonal, the support frame 23 divides the hexagonal intake port into six triangular windows, and one triangular blade is correspondingly provided in each triangular window.

[0101] In some embodiments, the fixed bracket is further provided with a surplus blade mounting port 22 located between adjacent intake unit mounting ports. A corresponding blade is mounted in the surplus blade mounting port 22. The linkage bracket moves and rotates the blade in the surplus blade mounting port 22 simultaneously in the process of rotating the blade of the intake unit. As long as space permits, surplus blade mounting ports 22 with different shapes and structures and corresponding blades can be installed as needed. Exemplarily, refer to FIGS. 34 and 40. In FIGS. 34 and 40, one triangular surplus blade mounting port 22 is provided at each of the upper and lower ends between two adjacent hexagonal intake unit mounting ports.

[0102] In some embodiments, the rotation angle of the blade 6 is 0 to 85°. In addition, the rotation angle of the intake grille blades can be controlled according to the heat dissipation requirements of the entire vehicle. The maximum rotation angle of the intake grille of the present application can reach 85°. Moreover, based on the multi-blade layout, when the blade opening angles are the same, compared with the conventional active intake grille, the effective intake area of the active intake grille of the present application is larger and the heat dissipation efficiency is improved.

[0103] In a preferred embodiment, the maximum rotation angle of the blade 6 is nearly perpendicular.

[0104] In some embodiments, the first link mechanism 4 may be a screw. The interlocking bracket is provided with a screw hole that matches the screw. The driving device is connected to the screw. The driving device directly drives the screw to rotate, and the screw is substantially perpendicular to the outer surface of the active intake grille. Thereby, when the screw moves, the interlocking bracket moves in conjunction and substantially perpendicular to the outer surface of the grille.

[0105] In some embodiments, as shown in FIGS. 13 and 15, the first link mechanism 4 may be a two-stage link motion mechanism, a Y-shaped eight-link motion mechanism, or other structures. The first link mechanism 4 is for moving the interlocking bracket, and its specific configuration is not limited to the above examples.

[0106] In some embodiments, as shown in FIGS. 28, 30, and 32, the second link mechanism 5 includes at least one of a lotus leaf motion mechanism, a scissor-type motion fork arm, and a Y-shaped eight-link motion mechanism. The second link mechanism 5 is used to transmit the force of the first link mechanism provided at the lower end of the interlocking bracket to the upper end of the interlocking bracket, so as to equalize the force received by the entire interlocking bracket and maintain the balance of motion. The specific configuration of the second link mechanism 5 is not limited to the above examples.

[0107] In some embodiments, the driving device is also provided with a reduction gear. In the process of the driving device driving the first link mechanism, the reduction gear can be used to increase the torque, and the gear ratio can be 1:2.6.

[0108] In some embodiments, the processing method of the external active intake grille is injection molding.

[0109] The closing process of the active intake grille of the present application is as follows. Under the drive of the driving device, the first link mechanism moves along the direction approaching the fixed bracket, whereby the interlocking bracket is pulled to perform a linear motion in the direction approaching the fixed bracket, and the interlocking bracket pushes the blade link mechanism to rotate it, and the blades are rotated along the rotation axis until all the blades are closed, thereby realizing the closing of the active intake grille.

[0110] The opening process of the active intake grille of the present application is as follows. Under the drive of the driving device, the first link mechanism moves in the direction away from the fixed bracket, whereby the interlocking bracket is pulled to perform a linear motion in the direction away from the fixed bracket, and the interlocking bracket pulls the blade link mechanism to perform a rotational motion, and the blades are rotated along the rotation axis. When the blades reach the desired rotation angle, the opening of the active intake grille is realized. In addition, according to different needs, by controlling the first link mechanism to move to different positions by the driving motor, it is realized that the blades open at different angles, and the effective intake area of the active intake grille is controlled.

[0111] The present application also provides a vehicle equipped with the active intake grille as described above.

[0112] By adopting the above-mentioned technical proposal, the active intake grille and the vehicle provided by the present application have the following advantageous effects.

[0113] By installing a plurality of blades, when the blade opening angles are the same, compared with the conventional active intake grille, the effective intake area of the active intake grille of the present application is significantly increased, and the heat dissipation efficiency is improved. By installing a plurality of blades, under the same blade area, the wind force is shared among the plurality of blades, enhancing the load-bearing capacity of the entire intake unit and making it less prone to breakage. In addition, by connecting multiple sets of blades to the linkage bracket, when the linkage bracket moves along the thickness direction of the linkage bracket, the opening and closing of the intake unit are realized, ensuring the synchronization of the movement of each blade.

[0114] By installing the first link mechanism and the second link mechanism, the force in the first link mechanism is transmitted to the second link mechanism, and the first link mechanism and the second link mechanism jointly move and drive the linkage bracket, ensuring the balance, synchronization and simultaneity of the linkage bracket during movement, and further enhancing the angle synchronization and angle stability during the rotation of the plurality of blades.

[0115] The present application provides a plurality of blades, and the rotation directions of the plurality of blades in a single intake unit are different from each other, thereby realizing the angular diversity of wind direction transmission and transmitting the incoming air to each position where heat dissipation of the vehicle is required.

[0116] The appearance surface of the active intake grille of the present application has an arc structure, providing a large available space in the vehicle. A bumper with a multi-type structure can be placed in this space, with a wide application range, and moreover, the appearance of the active intake grille of the present application is more aesthetically pleasing.

[0117] What has been described above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily come up with changes or substitutions within the technical scope disclosed by the present invention. All of these changes or substitutions should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should conform to the protection scope of the above-mentioned claims.
