[0031] The technical aspects of the embodiments of the present invention will be described below clearly and completely in accordance with the drawings in the examples of the present application. Obviously, the described examples are only some of the examples of the present application, but not all of the examples. Based on the examples of the present application, all other examples obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] In addition, in the description of this application, the orientation or positional relationship indicated by the term "end" etc. is based on the orientation or positional relationship shown in the drawings, and is merely for the purpose of facilitating and simplifying the description of this application, and does not indicate or imply that a specified component has a particular orientation or must be configured and operated in a particular orientation, and therefore cannot be understood as a limitation on this application.

[0033] <Example 1> As shown in Figs. 1 to 3, the present application provides a vehicle equipped with an active air intake grill. The active air intake grill includes a fixed bracket 1, an interlocking bracket 2, a driving device 3, a first link mechanism 4, and at least one air intake unit 10. The fixed bracket 1 is provided with an air intake unit mounting port, and the air intake unit mounting port is provided in one-to-one correspondence with the air intake unit 10. In this embodiment, the air intake unit 10 includes a plurality of blades 6 having 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 an edge of the air intake unit mounting port, and the first end of the blade 6 is spaced apart from the edge of the air intake unit mounting port relative 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 driving device 3 at different positions. The first link mechanism 4 is arranged to be driven by the driving device 3 and to move the interlocking bracket 2 to move. As a result, the blade link mechanism 7 rotates the blade 6 in interlocking with the interlocking bracket 2, and the blade 6 reverses relative to the fixed bracket 1 to open and close the intake unit 10. Note that the "open" or "closed" state of the intake unit 10 described above and in this specification means that the blade 6 reverses at any angle inside the vehicle. That is, all the descriptions regarding the "open" or "close" of the intake unit 10 described above and in this specification do not particularly mean that the intake unit 10 opens 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 is farther away from the edge of the intake unit mounting port than the second end of the blade 6, and the first end of the blade 6 is rotatably connected to the blade link mechanism 7, and the blade 6 can be turned back relative to the fixed bracket 1 under the driving of the blade link mechanism 7 to open and close the intake unit 10, so that in this embodiment, when the intake unit 10 is closed and then opened to a certain extent, air always flows into the active intake grill from between the multiple blades 6. At the same time, since the first end of the blade 6 is farther away from the edge of the intake unit mounting port than the second end of the blade 6, when the air enters the active intake grill in this embodiment, it does not deviate significantly from the traveling direction, as in the active intake grill using the conventional straight waterfall type blade B.

[0036] To explain this in more detail, as shown in FIG. 44, according to regulations, the exposed grille cannot be opened outward, i.e., cannot be turned around toward the outside of the vehicle, so the straight-water type blade B can only be turned around in one direction, i.e., toward the inside of the vehicle, and further opens the air inlet. In other words, the straight-water type blade B can only be opened in one direction. Based on the design that the straight-water type blade B can only be opened in one direction, it is obvious that under most of the opening angles of the straight-water type blade B, during the opening process of the straight-water type blade B, among the air that enters the vehicle from the outside of the vehicle through the air inlet, the traveling direction of a considerable part of the air deviates from the traveling direction, which of course has a negative effect on the effective air inlet area of ​​the grille and thus affects the heat dissipation efficiency. Correspondingly, as described above, the air inlet grille in the present invention does not cause such a situation. Based on this, the active air inlet grille according to this embodiment has the advantage of having a large effective air inlet area and improving the heat dissipation efficiency.

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

[0038] 1 and 2, six hexagonal intake unit mounting ports are provided in sequence on the fixed bracket 1, and the six hexagonal intake units 10 are attached to these six intake unit mounting ports in one-to-one correspondence, with each intake unit 10 having six triangular blades 6. For 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 at a certain angle inverted toward the rear of the vehicle with respect to the fixed bracket 1, that is, the three intake units 10 are in an open state.

[0039] For example, the fixed bracket 1 includes an exterior frame 1a and an inner frame 1b arranged in this order from the front to the rear of the vehicle. Here, the exterior frame 1a is located in front of the interlocking bracket 2, and the exterior frame 1a and the inner frame 1b are each provided with six hexagonal through-holes for forming the above-mentioned intake unit mounting port. At the same time, in order to ensure the overall strength of the intake unit mounting port, radial support frames 23 are provided across each of the through-holes provided in the exterior frame 1a.

[0040] Continuing to refer to FIG. 1 and FIG. 2, two interlocking brackets 2 of a substantially rectangular frame are installed in the active intake grille. One of the two interlocking brackets 2 is located on the rear side of the three intake units 10 on the left side of the actual vehicle, and the other is located on the rear side of the three intake units 10 on the right side of the actual vehicle. Exemplarily, the intake units 10 are configured to form an intake passage in the active intake grille between each blade 6 of the same intake unit 10 when the intake unit 10 is in an open state. The intake passage α continues to expand according to the opening degree of the blade 6 reversing toward the interior of the vehicle 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 a closed state, the intake passage α disappears. Each blade 6 in the same intake unit 10 is arranged so that when the interlocking bracket 2 moves in a direction away from the intake unit mounting port, the intake unit 10 opens and an intake passage α is formed between the blades 6. After the intake passage α is formed, the interlocking bracket 2 returns in a direction approaching the intake unit mounting port, and the intake passage α disappears. That is, while the interlocking bracket 2 moves in a direction approaching the intake unit mounting port, the intake passage α becomes smaller and smaller, and disappears when the reset of the blade 6 is completed. The direction moving away from the intake unit mounting port is generally from front to rear. The direction approaching the intake unit mounting port is generally from rear to front.

[0041] For example, the interlock bracket 2 is further provided with fitting openings 2a that correspond one-to-one to the intake units 10. The fitting openings 2a are disposed so as to penetrate the interlock bracket 2 and communicate with the intake passage α. As a result, when the intake unit 10 is open, the interlock bracket 2 has no solid part that blocks the rear side of the intake passage α and directly prevents air from entering. At the same time, the interlock bracket 2 has no solid part exposed through the intake passage α, ensuring the aesthetic appearance of the vehicle.

[0042] Furthermore, based on the above structure, a solution that is preferred but not necessarily adopted includes fixing mutually attractable magnetic parts to the inner frame 1b and the interlocking bracket 2. The beneficial effect of such an installation is that even if the active air intake grille is used for a long time and some fitting deviation occurs between its internal parts, and the interlocking bracket 2 cannot be moved to a predetermined position simply by being driven by the driving device 3, the inner frame 1b and the interlocking bracket 2 can still be fitted to a predetermined position by the magnetic attraction force of the magnetic parts because the above-mentioned mutually attractable magnetic parts are provided, and the blades 6 will not fail to close.

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

[0044] Continuing to refer to Figures 4 and 5, the first link mechanism 4 also illustratively includes a main shaft 42 and a plurality of sub-arms 43 connected together, and one end of each arm 43 is rotatably connected to the main shaft 42 or another sub-arm 43 or the drive shaft 41 in the orientation shown in Figures 6 and 7. The first link mechanism 4 is arranged such that one arm 43 shares a rotation axis with the drive shaft 41, the drive device 3 rotates the drive shaft 41, the drive shaft 41 moves and rotates the sub-arm 43 sharing the rotation axis therewith, and further moves the other sub-arm 43 and the main shaft 42, thereby forming the motion of the first link mechanism 4. For example, when the drive shaft 41 moves in the clockwise direction in FIG. 8, the other sub-arms 43 also move along the corresponding direction shown in FIG. 8 (for example, the sub-arm 43 at part I moves to one side while rotating in the counterclockwise direction in FIG. 8), and the first link mechanism 4 moves the interlock bracket 2 from front to back, transitioning 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 interlock bracket 2 can be returned from back to front, and the intake unit 10 can be closed again. In addition, in a possible embodiment, the drive shaft 41 may be one assembly with the drive device 3, may be one assembly with the first link mechanism 4, or may be a separate component independent of the first link mechanism 4 and the drive device 3.

[0045] 9, in order to clearly show the movement of each part of the first link mechanism 4, Fig. 9 shows a first link mechanism 4 located on the left side of the vehicle in this embodiment, and another first link mechanism 4 located on the right side of the vehicle in this embodiment. Here, the three intake units 10 corresponding to the former are all in an open state, and the corresponding blades 6 have a certain degree of opening reversing toward the inside of the vehicle, while the three intake units 10 corresponding to the latter are all in a closed state, and the corresponding blades 6 do not have an degree of opening reversing toward the inside of the vehicle.

[0046] Exemplarily, 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 (these four connection points 9 are filled in for easy illustration). The first link mechanism 4 is also rotatably connected to the interlocking bracket 2, and has five connection points 9 as shown in FIG. 11 and FIG. 12 (these five connection points 9 are filled in for easy illustration). In addition, the specific connection manner between the sub-arms 43 in the first link mechanism 4, between the sub-arms 43 and the main shaft 42, and between the sub-arms 43 and the drive shaft 41 can be flexibly set as needed, as long as those skilled in the art clearly know that the interlocking bracket 2 needs to move back and forth. For those skilled in the art, the disclosure of the specific form of the first link mechanism 4 is sufficient for those skilled in the art to implement this structure under the precondition of limited testing.

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

[0048] In particular, by applying any of the above-mentioned first link mechanisms 4 or the same flat link structure between the interlock bracket 2 and the fixed bracket 1, the driving device 3 can be arranged below the interlock bracket 2 and the fixed bracket 1, and it is not necessary to arrange the driving device 3 behind the interlock bracket 2 and the fixed bracket 1, which saves the interior space and also makes it easier for the designer to arrange the components (e.g., engine) that need to be cooled behind the active intake grille. Furthermore, from the viewpoint of structural design, the length of the first link mechanism 4 can be relatively easily designed to match the length of the interlock bracket 2 and the fixed bracket 1 in the left-right direction of the actual vehicle, and it is ensured that sufficient connection points 9 are arranged between the first link mechanism 4 and the interlock bracket 2 and that sufficient connection points 9 are arranged between the first link mechanism 4 and the interlock bracket 2 and that sufficient connection points 9 are arranged between the first link mechanism 4 and the fixed bracket 1, so that the structure formed by the first link mechanism 4, the interlock bracket 2, and the fixed bracket 1 has a sufficient connection strength, and it is ensured that the interlock bracket 2 can smoothly move the above-mentioned blade link mechanism 7, and that the blade 6 can be reversed to open and close the intake unit 10.

[0049] Please 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, and based on this, exemplarily, the blade link mechanism 7 is rotatably connected to the blade 6 and also engages with the blade 6, and 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 Figures 18 and 19. Exemplarily, each blade 6 is rotatably connected to the fixed bracket 1 by one rotation shaft 8. Exemplarily, the blade link mechanism 7 includes a main body 71 and a first engagement portion 72, the main body 71 is provided with a first base region 711, the first base region 711 and the first engagement portion 72 are connected, the first engagement portion 72 is provided in the first base region 711, the first engagement portion 72 includes a first shaft portion 721 and an engagement portion group 722 provided in order from proximal to distal from the main body 71, and the engagement portion group 722 includes a first engagement portion 7221 and a second engagement portion 7222. The first engagement portion 7221 and the second engagement portion 7222 are provided at an interval, respectively connected to the first shaft portion 721, and elastically deformable. Correspondingly, the blade 6 is provided with a second engagement portion 61, the engaging portion group 722 engages with the second engagement portion 61, and the first shaft portion 721 is rotatably connected to the second engagement portion 61. The second engagement 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 restrict at least a portion of the second engagement portion 61 therebetween, and thus to restrict separation of the blade link mechanism 7 and the blade 6.

[0051] Following the above, as a preferred but not necessarily adopted scheme for installing the blade link mechanism 7, the main body 71 is integrally molded 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 extending from the main body 71 to the outside of the main body 71, and the first engaging portion 7221 and the second engaging portion 7222 are formed extending from the first shaft portion 721 to the outside of the first shaft portion 721. 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 restrict at least a part of the second engaging portion 61 therebetween, and further restrict the separation of the blade link mechanism 7 and the blade 6.

[0052] In contrast to the above structure, another preferred but not necessarily required scheme is where the first shaft portion 721 is a cylinder of non-uniform diameter, the second engagement portion 61 is approximately sleeve-shaped (see Figure 20), and the maximum diameter of the first shaft portion 721 is such that a portion of the first shaft portion 721 abuts against the inner wall of the second engagement portion 61 while being positioned so as not to impede rotation of the first shaft portion 721.

[0053] As another preferable scheme to the above structure, but which does not necessarily have to be adopted, the first shaft portion 721 is rotatably connected to the second engagement portion 61 at the center of gravity of the blade 6. By disposing in this manner, it is possible to ensure that the force received by the blade 6 is stable, and the force (supplied by the drive device 3) required for reversing the blade 6 is not excessively large.

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

[0055] 22, in order to enhance the connection stability between the blade link mechanism 7 and the fixed bracket 1, the third engagement portion 73 further includes a third engaging portion 732. The third engaging portion 732 is spaced apart from the second shaft portion 731 and engages with the above-mentioned fourth engagement portion 2b. A preferred but not necessarily used configuration of the third engaging portion 732 includes that 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 thereof and includes a joint for forming an engaging relationship with the fourth engagement portion 2b, and the main body 71 and the joint cooperate with each other to restrict at least a part of the fourth engagement portion 2b therebetween, and further restrict the separation of the blade link mechanism 7 and the fixed bracket 1.

[0056] The blade link mechanism 7 is provided with the group of engaging parts 722, and when the third engaging part 732 is provided, this corresponds to both ends of the blade link mechanism 7 being engaged with the blade 6 and the interlocking bracket 2, respectively. By designing in this way, a reliable connection stability is ensured between the blade link mechanism 7 and the blade 6 and the interlocking bracket 2, and it is possible to ensure that the blade link mechanism 7 does not come off the blade 6 and the interlocking bracket 2 under various driving conditions (for example, when the vehicle shakes while driving).

[0057] Another suggestion, which is preferable but not necessarily required for the above structure, is as follows. As described above, when the engaging part group and the main body 71 restrict at least a part of the second engaging part 61 between them, and the third engaging part 732 and the main body 71 restrict at least a part of the fourth engaging part 2b between them, the margin for the second engaging part 61 to rotate 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 rotate 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 this arrangement is to leave an appropriate rotating space for the assembly chain of the three elements, the blade 6, the blade link mechanism 7 and the interlocking bracket 2, under the premise of ensuring that the blade link mechanism 7 does not come off. As a result, when the vehicle sways, the pitching force is transmitted to the three elements of the blade 6 - the blade link mechanism 7 - and the interlocking bracket 2, and the aforementioned force causes the fourth engagement portion 2b to slide between the third attachment portion 732 and the main body 71, and is consumed during this sliding, so that unnecessary mutual movement or collision between other closely assembled parts within the active intake grille and stress are not generated.

[0058] In addition to the above structure, another preferable but not necessary feature is that the positions of the first engagement portion 72 and the third engagement portion 73 on the main body 71 can be interchanged, and correspondingly, the characteristic form of the second engagement portion 61 on the blade 6 and the characteristic form of the fourth engagement portion 2b on the interlocking bracket 2 can also be interchanged.

[0059] Continuing to refer to Figures 18 and 19. Exemplarily, the blade link mechanism 7 includes an elastic portion 74 (for convenience of illustration, one elastic portion 74 is filled in). The elastic portion 74 is connected to the main body 71 and is used to abut against the interlocking bracket 2 so as to provide a cushioning effect when the blade link mechanism 7 and the interlocking bracket 2 move relative to each other.

[0060] Refer to FIG. 23. For the above-mentioned structure, another scheme, which is preferable but not necessarily adopted, includes that at least one through-hole 741 is provided in the elastic part 74, and the through-hole 741 is used to facilitate the deformation of a part of the elastic part 74 near the edge of the elastic part 74 located on its circumferential side. As shown in FIG. 24 and FIG. 25, another scheme, which is preferable but not necessarily adopted, includes that the number of the through-holes 741 is two or more, and different through-holes 741 are used to facilitate the deformation of different positions of the elastic part 74, and the different positions of the elastic part 74 play a buffering role at different times when the blade link mechanism 7 and the interlocking bracket 2 move. Another scheme, which is preferable but not necessarily adopted, includes that the through-hole 741 is polygonal or circular, and the elastic part 74 is integrally molded with the main body 71 by insert molding.

[0061] It is further necessary to explain that, as is clear from the above, the blade link mechanism 7 actually corresponds to a pivot adapter, that is, this embodiment further provides a pivot adapter. 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] The pivot adaptor is connected to a first member and a second member at different positions, and includes a main body 71 and a third engagement portion 73 connected to the main body 71. The main body 71 is provided with a second base region 712, and the third engagement portion 73 is provided in the second base region 712. The third engagement portion 73 includes a second shaft portion 731 and a third engagement portion 732 that are provided at a distance from each other. The second member is provided with a fourth engagement portion 2b. The second shaft portion 731 is for pivotally connecting with the fourth engagement portion 2b. The third engagement portion 732 is for connecting with the fourth engagement portion 2b. The main body 71 and the third engagement portion 732 cooperate with each other to restrict at least a part of the fourth engagement portion 2b between them, and are further used to restrict the movement of the fourth engagement portion 2b and to restrict the separation of the adapter from the second part.

[0063] Based on the above structure, it is also necessary to give some background on adapter configuration in the related art as follows:

[0064] In the related art, the transmission between parts often requires the use of an adapter. When one of the two parts is the first part and the other is the second part, the adapter needs to be connected to the first part and the second part at different positions, respectively, and in order to prevent the adapter from being separated from the parts, a corresponding stopper structure, such as a fastening part such as a fastening part C, needs to be designed in the structure formed by the adapter and the part to prevent the adapter from being separated from the part. Based on this, some connection structures between the adapter and the part include two spaced apart fastening parts C and one engagement hole D as shown in FIG. 45. Here, the two fastening parts C are integrally molded with the adapter and the solid part E, which is one of the parts, and are elastically deformable. When the adapter and the part need to be assembled, a force is applied to the two fastening parts C to make them approach each other temporarily, and then the two fastening parts C are inserted into the engagement hole D, and then the external force is removed to complete the engagement between the adapter and the corresponding part. At this time, the substantial portion E and the engaging portion C cooperate with each other to prevent the adapter and this member from coming apart from each other along a direction parallel to the center line of the engagement hole D.

[0065] Following on from the above, in a transmission structure using an adapter between a first member and a second member, the connection portion between the first member and the adapter and the connection portion between the second member and the adapter may be provided so as to form an engagement relationship using two engagement portions C. The disadvantage of such a scheme is that it is necessary to provide two pairs, i.e., a total of four engagement portions C, at once, which is likely to result in at least one of the following problems: high production cost for the fitting structure between the adapter and the part, high production precision, and high assembly difficulty (it is necessary to simultaneously apply force to the engagement portions C of different connection portions during assembly).

[0066] In response to this, the provided rotating adapter is provided with only the third engaging portion C at one end of the rotating part, and thus the adapter is connected to the second member and engaged with the second member by the engagement of the third engaging portion C with the main body 71. This has the advantage of lower production costs compared to the related art configuration in which four engaging portions C are provided. Secondly, the third engaging portion C and the second shaft portion 731 are provided at intervals, and therefore the production precision of this adapter is low. Finally, the third engaging portion C is provided at one end of the rotating part, and thus the adapter is connected to the second member and engaged with the second member by the engagement of the third engaging portion C with the main body 71. Therefore, in assembling the end where the third engaging portion C is located, a worker does not need to simultaneously press a pair of engaging portions C belonging to different ends, and the difficulty of assembling this adapter is low.

[0067] In addition, since one of the second member and the first member is the blade 6 and the other is the interlocking bracket 2, all of the settings related to the blade 6, interlocking bracket 2, and blade link mechanism 7 described above can be applied one-to-one to the second member, the first member, and the adapter.

[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 a first member, a second member and the aforementioned adapter. The adapter rotatably connects with the first member and the second member respectively at different positions thereof, and at the same time engages with the first member and the second member. The first member and the second member can be transmitted through the adapter.

[0069] 25. Illustratively, the active air intake grille further includes a second link mechanism 5. Corresponding to the installation of the first link mechanism 4 below the interlocking bracket 2, the second link mechanism 5 is connected to the upper end of the fixed bracket 1, the lower end of the fixed bracket 1, the upper end of the interlocking bracket 2, and the lower end of the interlocking bracket 2. When the first link mechanism 4 moves the interlocking 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. The at least two connection points are located at two opposite ends of the interlocking bracket 2, respectively. The second link mechanism 5 has at least two connection points with the fixed bracket 1. The at least two connection points are located at two opposite ends of the fixed bracket 1, respectively.

[0071] Following on from the above, the second link mechanism 5 is used to transmit 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 properly under any driving conditions, and ensuring the structural strength and modality of the system formed between the blade 6-interlocking bracket 2-fixed bracket 1.

[0072] To explain this in more detail, since the first link mechanism 4 is provided under the interlocking bracket 2 and is located between the interlocking bracket 2 and the fixed bracket 1, the first link mechanism 4 is provided under the active air intake grille and is equivalent to moving the interlocking bracket 2 by "push-pull". Based on this, first, when it is necessary to counter strong wind force, such as when the vehicle is driving on a highway, the active air 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 reversal movement under strong wind force to open and close the air intake unit 10. Secondly, since the second link mechanism 5 is connected to the upper and lower ends of the interlocking bracket 2 and also to the upper and lower ends of the fixed bracket 1, the system of the blade 6-interlocking bracket 2-fixed bracket 1 can transmit force and is equivalent to the existence of a solid movable bridge. This must be able to increase the structural strength and modality of the entire system and at the same time increase the structural strength and modality of the entire active air intake grille.

[0073] 26. Exemplarily, the second link mechanism 5 includes a first divided body 51 and a second divided body 52 that are rotatably connected to each other. 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. Furthermore, a preferred but not necessarily required installation includes that one of the first divided body 51 and the second divided body 52 is provided with an axis region 53, and the other is provided with a rotation coupling portion 54, and the rotation coupling portion 54 is rotatably connected to the axis region 53. FIG. 26 shows a schematic diagram of a case where the axis region 53 is provided in the first divided body 51, and the rotation coupling portion 54 is provided in the second divided body 52.

[0074] As a preferred, but not necessarily required, arrangement, the rotary coupling 54 is a sleeve with an open side that is integrally molded on one of the first division 51 and the second division 52, and the shaft region 53 is a cylinder that is integrally molded on the other of the first division 51 and the second division 52. In FIG. 26, a configuration is adopted in which the shaft region 53 is provided on the first division 51, and the rotary coupling 54 is provided on the second division 52.

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

[0076] 2, in the active air intake grille, the second link mechanism 5 is connected to the upper left corner and lower left corner of the actual vehicle of the interlocking bracket 2, and is also connected to the upper left corner and lower left corner of the actual vehicle of the fixed bracket 1. In addition, the second link mechanism 5 is connected to the upper right corner and lower right corner of the actual vehicle of the interlocking bracket 2, and is also connected to the upper right corner and lower right corner of the actual vehicle of the fixed bracket 1.

[0077] Continuing to refer to Fig. 27, as a preferred but not essential feature, the second divided body 52 further includes a force component 55 that protrudes upward relative to the circumferential side.

[0078] As shown in FIG. 25, the purpose of installing the force dividing unit 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 is reversed from inside the vehicle to outside the vehicle until the intake unit 10 is closed, it may come into contact with the support frame 23 of the exterior frame 1a, and the judgment condition (i.e., the operation logic) for the drive unit 3 to stop moving the interlocking bracket 2 forward is that when the drive unit 3 encounters a certain resistance, it stops moving the interlocking bracket 2 forward. Here, the aforementioned "certain resistance" means that when the blade 6 reverses until the intake unit 10 is closed, the blade 6 is hindered by the support frame 23 of the exterior frame 1a, and a certain value of reaction force is generated between the blade 6 and the support frame 23.

[0079] In other words, under the above judgment logic, for the judgment condition to be met for the driving device 3 to stop moving the interlocking bracket 2 forward, it is actually required that the blade 6 first collides with the support frame 23 under the driving of the driving device 3, and the force of the blade 6 colliding with the support frame 23 is transmitted to the driving device 3 as resistance.

[0080] Based on this, the force component 55 is provided and arranged so that when the blade 6 collides with the support frame 23, the first divided body 51 collides with the force component 55 at the same time. This causes the force generated when the first divided body 51 collides with the force component 55 to be fed back to the driving device 3 in the form of resistance, and the resistance received by the driving device 3 actually changes to a resultant force formed by the force between the first divided body 51 and the force component 55 and the force between the blade 6 and the support frame 23. This resultant force can easily satisfy the judgment condition of the driving device 3, and the driving device 3 can immediately stop the forward movement of the interlocking bracket 2. Based on this, since there is a force between the first divided body 51 and the force component 55 that shares a numerical value, the force that the blade 6 should receive is naturally reduced in the process of the blade 6 colliding with the support frame 23. This design can reduce the probability of the blade 6 being deformed in appearance (for example, the surface being dented due to excessive collision with the support frame 23) during long-term use of the active intake grille.

[0081] In addition, when designing the blade 6 as a barrier and providing the drive unit 3 with resistance that satisfies the judgment conditions, instead of the above-mentioned method of colliding the blade 6 with the support frame 23, a separate stopper feature may be provided in the rotation trajectory of the blade 6 at the fixed bracket 1.

[0082] In addition, the second link mechanism 5 can adopt the above configuration, and 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 can be in a form as shown in FIG. 28, and has a motion schematic diagram and expected motion stroke as shown in FIG. 29. Points [1] and [2] in FIG. 29 respectively indicate the connection between the second link mechanism 5 and the upper end and lower end of the actual vehicle of the interlocking bracket 2. The second link mechanism 5 can be in a form as shown in FIG. 30, and has a motion schematic diagram and expected motion stroke as shown in FIG. 31. Points [3] and [4] in FIG. 31 respectively indicate the connection between the second link mechanism 5 and the upper end and lower end of the actual vehicle of the interlocking bracket 2. The second link mechanism 5 can be in a form as shown in FIG. 32, and has a motion schematic diagram and expected motion stroke as shown in FIG. 33. Points [5] and [6] in FIG. 33 respectively indicate the connection between the second link mechanism 5 and the upper end and lower end of the actual vehicle of the interlocking bracket 2.

[0083] In addition, based on the above configuration, this embodiment actually further provides a kind of moving structure, in which the interlocking bracket 2 is a moving demand member and the fixed bracket 1 is a position fixing member. The installation principle of this moving structure is as follows: it includes a moving demand member, a position fixing member, a first link mechanism 4 and a 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 demand member, and is respectively connected to the moving demand member and the position fixing member at different positions, the second link mechanism 5 is respectively connected to the moving demand member and the position fixing member at different positions, the first link mechanism 4 can move the moving demand member to move relative to the position fixing member by an external force, and the second link mechanism 5 can move adaptively.

[0084] There are at least two connection points between the second link mechanism 5 and the moving demand member. The at least two connection points of the second link mechanism 5 are located at two opposing ends of the moving demand member, respectively. There are at least two connection points between the second link mechanism 5 and the position fixing member. The at least two connection points of the second link mechanism 5 are located at two opposing ends of the position fixing member, respectively. The second link mechanism 5 is used to transmit the force transmitted from the first link mechanism 4 to the connection part with the moving demand member to the entire moving demand member.

[0085] The second link mechanism 5 includes a first divided body 51 and a second divided body 52 which 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. One of the first divided body 51 and the second divided body 52 is provided with an axis region 53, and the other is provided with a rotational coupling portion 54. The rotational coupling portion 54 is rotatably connected to the axis region 53.

[0086] Furthermore, since the position fixing member is the fixed bracket 1 and the movable member is the interlocking bracket 2, all of the above-mentioned installations of the fixed bracket 1 and the interlocking bracket 2 are applicable to the position fixing member and the movable member in one-to-one correspondence.

[0087] Based on the above configuration, some background of providing a moving structure in the related art should also be explained. In the related art, if a moving member needs to be moved back and forth along a predicted trajectory relative to a fixed and immovable position fixing member, for example, if the moving member needs to be moved back and forth relative to the position fixing member, the general design plan is as follows. As shown in Figure 46, the side of the moving member is connected to a motor assembly G with a telescopic rod F for a driving device, and on the premise that the telescopic rod F is parallel to the front and rear directions, the moving member is driven by the motor assembly G to realize a reciprocating motion.

[0088] The disadvantage of such a design is that when the contact position between the motor assembly G and the moving member is not the center of gravity of the moving member, and the volume of the moving member is much larger than the contact area between the telescopic rod F and the moving member, the moving member is pushed by only one point. Since the moving member is pushed by only one point, if the moving member is also subjected to other external forces (for example, when it is necessary to resist strong wind force), the movement stability of the moving member is likely to decrease.

[0089] Correspondingly, the above-mentioned moving structure has a second link mechanism 5, which forms a bridge-like entity for rapid force transmission between the moving member and the fixed member, and can enhance the structural strength and modality of the entire moving structure through the connection between itself, the moving member and the fixed member, so that the moving structure provided by this embodiment has good movement stability compared to the related art. Similarly, the moving member therein also has good movement stability.

[0090] <Example 2> The present application provides a type of active air intake grille. As shown in Figs. 34-43, 13, 15, 28, 30 and 32, the active air intake grille includes a fixed bracket 1, an interlocking bracket 2, a driving device 3, a first link mechanism 4 and at least one air intake unit 10. The air 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 a first end of each of the vane link mechanisms 7 among the plurality of vane link mechanisms 7, and a second end of each of the vane link mechanisms 7 is rotatably connected to a first end of each of the blades 6 in a one-to-one relationship. 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 drive device 3 drives and moves the first link mechanism 4, the first link mechanism 4 moves and moves the interlocking bracket 2, the interlocking bracket 2 moves and 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, and under the driving action of the driving device 3, the driving shaft 41 of the first link mechanism 4 moves to move the first link mechanism 4. 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 to move along the thickness direction of the interlocking bracket 2. Since 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, 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, and when the blade 6 rotates, the intake unit 10 opens to achieve the intake effect. When the blade opening angle is the same, the effective intake area of ​​the active intake grille of the present application is obviously increased compared with the conventional active intake grille, and the heat dissipation efficiency is improved. In addition, in the present application, multiple blades are installed, and wind force is shared among the multiple blades under the same blade area, thereby increasing the strength of the entire intake unit 10 and making it less likely to break. In the present application, multiple sets of blades are connected to the interlocking bracket, thereby ensuring the synchronization of the movement of each blade in the process in which the interlocking bracket moves 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, and by fixedly connecting the first link mechanism 4 to the fixed bracket 1, the movement of the interlocking bracket 2 is stabilized when the first link mechanism 4 moves the interlocking bracket 2 toward or away from the second end of the blade 6.

[0093] In some embodiments, the active air intake grill further includes a second link mechanism 5. 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. The first link mechanism 4 may be provided in the longitudinal direction of the active air intake grill. That is, the first link mechanism 4 may be provided at the bottom of the active air intake grill after the active air intake grill is mounted on the vehicle. The second link mechanism 5 may be provided in the width direction of the active air intake grill. That is, the first link mechanism 4 may be provided at the side of the active air intake grill after the active air intake grill is mounted on the vehicle. In the present application, the first link mechanism 4 and the second link mechanism 5 are provided, the second link mechanism 5 is driven via the first link mechanism 4, and the first link mechanism 4 and the second link mechanism 5 jointly drive and move the interlocking bracket 2, thereby ensuring balance, synchronization, and simultaneity during the movement of the interlocking bracket 2, and further improving the angular synchronization and angular stability when multiple blades rotate.

[0094] In some embodiments, the active air intake grill includes a first air intake section 11 and a second air intake section 12. The first air intake section 11 and the second air intake section 12 are provided with a drive device 3, a first link mechanism 4, and at least one air intake unit 10, respectively. The drive device 3 is electrically connected to a controller of the vehicle. The controller is used to individually control the single drive device 3. In the present application, the entire active air intake grill is divided into at least the first air intake section 11 and the second air intake section 12, and the blade movement direction of the first air intake section 11 and the second air intake section 12 can be independently controlled by an independent driving motor, and the blade movement direction and the rotation angle of both blades may or may not be the same, and the opening angle of the blade in the air intake unit 10 of the first air intake section 11 and the second air intake section 12 can be set as necessary, and the applicability is wide. Preferably, the first air intake section 11 and the second air intake section 12 are provided with a second link mechanism 5, respectively.

[0095] In some embodiments, the at least two blades 6 are not parallel to each other such that the orientations of the at least two blades 6 are not aligned when the intake unit 10 is in an open state, thereby realizing multiple angles of intake of the intake unit 10 when the intake unit 10 is in an open state.

[0096] In some embodiments, the second end of the blade linkage 7 is pivoted to the free end of the blade 6, and the connecting end of the blade 6 is pivoted to the fixed bracket 1. A single blade 6 is pivoted to at least one blade linkage 7. The number of blade linkages 7 can be set as required and is not limited here.

[0097] In some embodiments, as shown in Figs. 36-39, a rotating shaft is provided at the connection between the blade 6 and the fixed bracket 1, and the blade 6 can move along the rotating shaft in a direction away from the fixed bracket 1. The rotating directions of the multiple blades 6 in a single air intake unit 10 are different from each other. The present application saves more internal space compared to single-opening or double-opening (i.e., opening from two directions). In addition, the regulations require that the external air intake grille cannot open outward. The single-opening shaft does not meet the legal requirements when it is in the middle. In addition, when the shaft opens inward from the side, a lot of internal space is wasted. The multi-directional inward opening method of the present application can save internal space and meet the requirements for the amount of intake air. On the other hand, the single-opening intake direction deviates from the running direction, which has a certain effect on the stability of the vehicle body when the vehicle speed is high. The double-opening blade of the present application opens symmetrically, and the intake direction and the running direction are the same, so there is no effect on the stability of the vehicle body. The rotation shaft may be a full shaft or a half shaft. Preferably, the rotation axis is a full axis, which improves safety performance during operation of the intake grille.

[0098] In some embodiments, the exterior surface of the active air intake grille is an arc structure. The arc structure of the exterior surface of the active air intake grille of the present application allows the active air intake grille to move within the arc surface, and the arc structure provides a large usable space after the active air intake grille is installed on the vehicle. This space can be used to place bumpers with multiple types of structures, which has a wide range of applications. Moreover, the appearance of the active air intake grille of the present application is more aesthetic.

[0099] In some embodiments, refer to FIG. 43. FIG. 43 is a schematic diagram of an intake grill of an intake unit 10 of a different shape according to an 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 a circular-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 in a ring shape. Exemplarily, when the blades are triangular and three blades are installed in one intake unit 10, the shape formed by closing the three blades is triangular, that is, one intake unit 10 is triangular, specifically refer to FIG. 43(c). When the blades are triangular and four blades are installed in one intake unit 10, the shape formed by closing the four blades is square, that is, one intake unit 10 is quadrangular, specifically refer to FIG. 43(d). When the blades are triangular and one intake unit 10 is provided with five blades, the shape formed by the five blades closing is a pentagon, that is, one intake unit 10 is a pentagon, specifically see FIG. 43(a). When the blades are triangular and one intake unit 10 is provided with six blades, the shape formed by the six blades closing is a hexagon, that is, one intake unit 10 is a hexagon. When the blades are fan-shaped and one intake unit 10 is provided with four blades, the shape formed by the four blades closing is a circle, that is, one intake unit 10 is a circle, specifically see FIG. 43(b). The shape and structure of the interlocking bracket can be adaptively modified according to changes in the shape and structure of the blades.

[0100] In some embodiments, the fixed bracket is provided with an intake unit mounting port. The intake unit mounting port is provided in one-to-one correspondence with the intake unit 10. The shape of the intake unit mounting port includes at least one of a circle and a polygon. The blades are arranged in the circumferential direction along the edge of the intake unit mounting port. A support frame 23 is provided inside the intake unit mounting port. For example, when the intake unit 10 is hexagonal, the support frame 23 divides the hexagonal intake port into six triangular windows, and each triangular window is provided with one corresponding triangular blade.

[0101] In some embodiments, the fixed bracket is further provided with an excess blade mounting hole 22 located between the adjacent intake unit mounting holes. A corresponding blade is mounted in the excess blade mounting hole 22. In the process of rotating the blade of the intake unit, the interlocking bracket simultaneously moves and rotates the blade in the excess blade mounting hole 22. As long as space allows, excess blade mounting holes 22 of different shapes and structures and corresponding blades can be installed as needed. For example, see Figures 34 and 40. In Figures 34 and 40, one triangular excess blade mounting hole 22 is provided at the upper and lower ends between two adjacent hexagonal intake unit mounting holes.

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

[0103] In a preferred embodiment, the maximum pivot angle of the blade 6 is as close to a right angle as possible.

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

[0105] In some embodiments, the first link mechanism 4 may be a two-stage link mechanism, a Y-shaped eight-link mechanism, or other structures, as shown in Figures 13 and 15. 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 Figures 28, 30 and 32, the second link mechanism 5 includes at least one of a lotus leaf motion mechanism, a scissors-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, thereby making the force received by the entire interlocking bracket uniform and maintaining the balance of the 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 in which the driving device drives 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 fabrication method for the external active air intake grille is injection molding.

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

[0110] The opening process of the active air intake grille of the present application is as follows: under the driving of the driving device, the first link mechanism moves away from the fixed bracket, thereby pulling the interlocking bracket to perform a linear movement away from the fixed bracket, and the interlocking bracket pulls the blade link mechanism to perform a rotational movement, causing the blade to rotate along the rotation axis. When the blade is at a desired rotation angle, the active air intake grille is opened. In addition, according to different needs, the first link mechanism can be controlled to move to different positions by the driving motor to achieve the blade opening at different angles, thereby controlling the effective air intake area of ​​the active air intake grille.

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

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

[0113] By installing multiple blades in the present application, when compared with conventional active air intake grilles at the same blade opening angle, the effective air intake area of ​​the active air intake grille of the present application is significantly increased and the heat dissipation efficiency is improved. By installing multiple blades in the present application, wind force is shared among multiple blades under the same blade area, improving the strength-bearing capacity of the entire air intake unit and making it less likely to break. In addition, by connecting multiple sets of blades to an interlocking bracket, the air intake unit can be opened and closed during the process of the interlocking bracket moving along the thickness direction of the interlocking bracket, and the synchronization of the movement of each blade is ensured.

[0114] By installing a first link mechanism and a second link mechanism, the present application transmits the force in the first link mechanism to the second link mechanism, and the first link mechanism and the second link mechanism jointly move the interlocking bracket to ensure balance, synchronization and simultaneity when the interlocking bracket moves, and further improves the angular synchronization and angular stability when multiple blades rotate.

[0115] In the present application, by providing a plurality of blades and varying the rotation directions of the plurality of blades in a single intake unit, angular diversity in wind direction transmission is realized, and the incoming air is transmitted to each location in the vehicle where heat dissipation is required.

[0116] The exterior surface of the active air intake grille of the present application is a circular arc structure, which provides a large usable space in the vehicle, and multiple types of bumpers can be placed in this space, which has a wide range of applications, and the appearance of the active air intake grille of the present application is more aesthetic.

[0117] The above is merely a specific embodiment of the present invention, and the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of modifications or replacements within the technical scope disclosed in the present invention. All of these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be in accordance with the protection scope of the claims. [Explanation of symbols]
