[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] With the continuous development of the automobile industry in recent years, the pursuit of automobile styling has become more and more diversified. OEMs improve the diversity of the overall front styling and aerodynamic performance by placing the air intake grille blades in front. In the above solution, the active air intake grille and the front bumper are integrated in shape, which will cause the opening angles of different grille blades to be inconsistent when fully opened.

[0052] The main purpose of the present invention is to provide a driven structure, a driving mechanism, an air intake grille module and a vehicle, aiming to meet the problem that the opening angles of different blades are inconsistent when they are fully opened.

[0053] See also Figure 1 and Figure 2 The present invention proposes a driven structure 10, on which a transmission connection part 11 and a mounting structure group are formed, and the mounting structure group includes at least two rotating mounting parts 12, and the transmission connection part 11 is used for transmission connection to the driving motor 20 of the air intake grille module 1000, and each of the rotating mounting parts 12 is used for rotationally mounting on a blade 300 provided at the grille opening in a one-to-one correspondence, so that each of the blades 300 can rotate to open and close the grille opening.

[0054] The rotation centers formed on at least two of the rotating installation parts 12 in the installation structure group are arranged to have different rotation radii relative to the transmission connection part 11 .

[0055] In the technical solution of the present invention, a transmission connection part 11 and a mounting structure group are formed on the driven structure 10, and the mounting structure group includes at least two rotating mounting parts 12. The rotation centers formed on at least two rotating mounting parts 12 in the mounting structure group are arranged differently relative to the rotation radius of the transmission connection part 11. When the transmission connection part 11 rotates a certain angle, the rotation radii of the two rotating mounting parts 12 are inconsistent, which directly leads to inconsistent rotation angles of the two rotating mounting parts 12, that is, the opening angles of at least some blades 300 are inconsistent when they are fully opened.

[0056] It should be noted that, in the blade group, the number of blades 300 is not limited, and may be 2, 3 or more. Correspondingly, in the mounting structure group, the number of rotating mounting parts 12 may be 2, 3 or more, and the rotating mounting parts 12 and the blades 300 in the blade group are arranged in a one-to-one correspondence.

[0057] In addition, in the installation structure group, the number of the rotating installation parts 12 with different rotation radius can also be set to 2, 3 or more.

[0058] In the above-mentioned number setting, it can be understood that, for example, in the installation structure group, the number of the rotating mounting parts 12 set is 2, then the number of the rotating mounting parts 12 set with different rotation radii is also 2, and correspondingly, in the blade group, the number of the blades 300 set is 2.

[0059] For example, in the installation structure group, the number of the rotating installation parts 12 is 3, then the number of the rotating installation parts 12 with different rotation radii can be set to 2 or 3, that is, the rotation radii of all the rotating installation parts 12 can be inconsistent, or the rotation radii of some of the rotating installation parts 12 can be inconsistent; correspondingly, in the blade group, the number of the blades 300 is 3.

[0060] When the number of the rotatable mounting parts 12 is more than 3, please refer to the number of the rotatable mounting parts 12 being 3 for setting.

[0061] In the following description, it is mainly explained that two rotating mounting parts 12 are provided in the mounting structure group and two blades 300 are provided in one blade group.

[0062] It can be understood that the air intake grille module 1000 is an active air intake component, which usually includes a grille frame, on which a grille opening is provided, and a blade 300 is rotatably installed at the edge of the grille opening. For one grille opening, there can be multiple blades 300, and the multiple blades 300 rotate in conjunction to open or close the grille opening.

[0063] Please note that Figure 1 The rotational radii of the rotational centers formed on the two rotating mounting parts 12 relative to the transmission connection part 11 are R1 and R2 respectively. Figure 1 It can be seen that the sizes of the two are different. After the drive motor 20 transmits the torque to the transmission connection part 11, the transmission connection part 11 will rotate. The farther the rotating mounting part 12 is from the transmission connection part 11, the greater the amplitude of the rotation center formed on the rotating mounting part 12 relative to the transmission connection part 11, and the larger the opening angle of the blade 300; on the contrary, the closer the rotating mounting part 12 is to the transmission connection part 11, the smaller the amplitude of the rotation center formed on the rotating mounting part 12 relative to the transmission connection part 11, and the smaller the opening angle of the blade 300.

[0064] It should be noted that in the above structure, please refer to Figure 7 A rotating connection part 301 and a driving connection part 302 are respectively provided at both ends of each blade 300. The rotating connection part 301 is used to be rotatably installed at the edge of the grille opening. The setting of the rotating connection part 301 and the driving connection part 302 directly determines whether the driven structure 10 can drive the two blades 300 to rotate.

[0065] In some extreme embodiments, the rotating connection part 301 and the driving connection part 302 can be coaxially arranged; in other embodiments, the rotating connection part 301 and the driving connection part 302 are arranged off-axis, that is, the rotation center lines of the two are not arranged to overlap. When the driven structure 10 rotates, the driving connection parts 302 of the two blades 300 can rotate around the rotating connection parts 301 of the blades 300, thereby driving each of the blades 300 to rotate.

[0066] In some embodiments, for one blade 300 , two rotation connection parts 301 are provided, which are disposed at both ends of the blade 300 and are coaxially arranged. Such an arrangement improves the rotation stability of the blade 300 .

[0067] A transmission connection part 11 and at least two rotating mounting parts 12 are formed on the driven structure 10. The driven structure 10 can be integrally formed. With this arrangement, the molding method is simple and the cost is low compared to the machining method.

[0068] The driving connection part 302 and the rotating installation part 12 are rotationally matched. One of the driving connection part 302 and the rotating installation part 12 is set as a hole part, and the other is set as a shaft part. The shaft part is rotationally installed in the hole part to achieve rotational connection.

[0069] In some embodiments, the driving connection portion 302 is configured as a driving connection hole portion, and correspondingly, the rotating mounting portion 12 is configured as a rotating shaft portion 12a, and the rotating shaft portion 12a is rotatably installed in the driving connection hole portion, that is, the rotating mounting portion 12 on the driven structure 10 is configured as the rotating shaft portion 12a, which is easy to demold during the integral molding process of the driven structure 10, and is convenient for manufacturing.

[0070] The transmission connection part 11 can be set as a hole part or a shaft part. In some embodiments, the transmission connection part 11 is set as a transmission connection shaft part 11a, which is easy to demold during the integral molding of the driven structure 10 and is convenient for manufacturing.

[0071] In view of the above structure, the transmission connection part 11 and the two rotating installation parts 12 are both configured as shaft parts, that is, they are easy to demould during the integral molding of the driven structure 10, and are convenient for manufacturing.

[0072] The rotating connection part 301 can be set as a hole part or a shaft part. In some embodiments, the rotating connection part 301 is set as a rotating connection shaft part to be rotatably installed with the installation hole provided on the grille frame. In this way, the installation of the blade 300 is convenient.

[0073] As for the arrangement of the at least two rotating mounting parts 12 and the transmission connection part 11, the at least two rotating mounting parts 12 can be arranged on the same side, or can be arranged on opposite sides of the driven structure 10. The transmission connection part 11 can be arranged on the same side as the at least two rotating mounting parts 12, or can be arranged on different sides.

[0074] In some embodiments, the driven structure 10 includes a driven body having two opposite side surfaces, and all of the rotating mounting portions 12 in the mounting structure group are arranged on the same side surface, so as to facilitate connecting each blade 300 on the same side of the driven body and facilitate the layout of the structure.

[0075] In some embodiments, the mounting structure group and the transmission connection part 11 are separately arranged on the two sides, that is, the mounting structure group and the transmission connection part 11 are separately arranged on different sides of the driven body, which is easy to demold during the integral molding process of the driven structure 10 and facilitates manufacturing.

[0076] It should be noted that, in the above two embodiments, the at least two rotating mounting parts 12 and the transmission connection part 11 in the mounting structure group may be arranged one by one or both at the same time.

[0077] The rotating shaft portion 12a and the driving connection hole portion are rotatably connected, and the two need to be limited in the axial direction. In some embodiments, a first limiting protrusion 121 is provided on the rotating shaft portion 12a, and the first limiting protrusion 121 can be set to move radially along the rotating shaft portion 12a, that is, before the driving connection hole portion is inserted into the rotating shaft portion 12a, the first limiting protrusion 121 moves radially inward along the rotating shaft portion 12a to avoid the driving connection hole portion; after the driving connection hole portion and the rotating shaft portion 12a are installed in place, the first limiting protrusion 121 moves radially outward along the rotating shaft portion 12a to press against the hole edge of the driving connection hole portion to limit the relative movement of the rotating shaft portion 12a and the driving connection hole portion in the axial direction.

[0078] As for the manner in which the first limiting protrusion 121 can be movably arranged along the radial direction of the rotating shaft portion 12a, a linear driving device can be arranged inside the rotating shaft portion 12a, and the linear driving device includes a driving portion movably installed along the radial direction of the rotating shaft portion 12a, and the driving portion is connected to the first limiting protrusion 121 to realize the movement of the first limiting protrusion 121.

[0079] In some embodiments, the rotating shaft portion 12a is hollow, and the outer wall of the rotating shaft portion 12a is partially hollowed out to form an elastic arm 122. The first limiting protrusion 121 is arranged at the free end of the elastic arm 122. With this arrangement, the adaptive movement of the first limiting protrusion 121 can be achieved without the need for an additional driving device, and the structure is simple.

[0080] The elastic arm 122 may be formed by integrally molding the rotating shaft portion 12 a and then processing a hollow structure on the rotating shaft portion 12 a .

[0081] The transmission connection part 11 is mainly used to connect with the driving spindle 30. In order to limit the axial movement between the transmission connection part 11 and the driving spindle 30, a limiting structure can be set on the driving spindle 30 or on the transmission connection part 11.

[0082] In some embodiments, the transmission connection part 11 is configured as a transmission connection shaft 11a, and a second limiting protrusion 123 is provided at the end of the transmission connection shaft 11a. The second limiting protrusion 123 can be used to realize axial movement between the transmission connection part 11 and the driving spindle 30, and the structure is simple.

[0083] As for the second position-limiting protrusion 123 , the second position-limiting protrusion 123 may be a convex block or a disc portion, both of which are embodiments of the present invention.

[0084] See also Figures 3 to 6 The present invention further proposes a driving mechanism 100 , which includes a driving motor 20 , a driving spindle 30 and a driven structure 10 .

[0085] The specific structure of the driven structure 10 refers to all the above embodiments. Since the driving mechanism 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0086] In the driving mechanism 100, one end of the driving main shaft 30 is drivingly connected to the driving motor 20, and the other end is provided with an eccentric protrusion 301. The transmission connection part 11 of the driven structure 10 includes a transmission connection shaft 11a, and the transmission connection shaft 11a is rotatably connected to the eccentric protrusion 301 and can rotate eccentrically relative to the driving main shaft 30.

[0087] The main shaft of the driving motor 20 rotates to drive the driving main shaft 30 to rotate. The driving main shaft 30 transmits the torque to the driven structure 10 through the eccentric convex part 301, thereby driving the two blades 300 to rotate, thereby realizing the opening and closing of the grille opening on the grille frame.

[0088] Understandably, please refer to Figure 4 The eccentric protrusion 301 extends from the side of the driving main shaft 30 and is provided with a mounting groove 3011 at its end. The mounting groove 3011 is arranged to penetrate along the axial direction of the driving main shaft 30, and the transmission connection shaft 11a is rotatably installed in the mounting groove 3011.

[0089] When assembling the driven structure 10 and the driving spindle 30 , the transmission connection shaft portion 11 a can be clamped into the installation groove 3011 from the notch of the installation groove 3011 , which is very convenient for assembly and improves assembly efficiency.

[0090] In some embodiments, the mounting groove 3011 has two opposite groove side walls. At the groove mouth adjacent to the mounting groove 3011, at least one of the groove side walls is provided with a third limiting protrusion 3012 for limiting the radial jump of the transmission connection shaft portion 11a from its radial direction so as to disengage from the mounting groove 3011. The radial jump of the transmission connection shaft portion 11a from its radial direction can be limited by a simple structure, and the limiting effect is better.

[0091] It should be noted that, before assembling the driven structure 10 and the driving spindle 30, the width defined by the third limiting protrusion 3012 in the installation groove 3011 is smaller than the diameter of the driving spindle 30. When installing the transmission connection shaft portion 11a, the two groove side walls at the groove opening of the installation groove 3011 are deformed away from each other to form an expansion, and after the driving spindle 30 is inserted into the installation groove 3011, the two groove side walls recover their deformation to limit the driving spindle 30.

[0092] The third limiting protrusion 3012 can be a long rib arranged on the side wall of the installation groove 3011, or can be a structure such as a protrusion.

[0093] In some embodiments, the third limiting protrusions 3012 are provided on both side walls of the installation groove 3011, and the two third limiting protrusions 3012 are arranged opposite to each other.

[0094] In order to limit the opening angle of the blade 300, some limiting structures may be provided on the blade 300 to limit the opening angle of the blade 300, such as providing a limiting baffle, etc.; a limiting structure may also be provided on the driven structure 10, and a matching structure may be provided on the grille frame to limit the rotational travel of the driven structure 10, thereby limiting the opening angle of the blade 300.

[0095] In some embodiments, a limiting rib 302 may be provided on the driving main shaft 30 , and the limiting rib 302 and a matching portion provided on the grille frame may be used to limit the rotational travel of the driving main shaft 30 , thereby limiting the opening angle of the blade 300 .

[0096] Specifically, the side surface of the driving shaft 30 is convexly provided with a limiting rib 302 extending along its circumference, and two abutting surfaces 3021 are formed at both ends of the limiting rib 302. The two abutting surfaces 3021 are used to alternately abut with two stop surfaces 401 provided on the mounting seat 400 of the air intake grille module 1000 to limit the rotation stroke of the driving shaft 30. In this way, a limiting structure is directly provided on the driving shaft 30 to indirectly limit the opening angle of the blade 300, and the limiting is directly performed at the source of the entire transmission chain, with a good limiting effect.

[0097] It can be understood that the mounting seat 400 is used to carry the driving mechanism 100, and then the mounting seat 400 is detachably mounted on the grid frame. Such an arrangement can simplify the arrangement of the grid frame and facilitate processing.

[0098] See also Figure 3 and Figure 5 A receiving groove is formed on the mounting seat 400, and a placement groove is also formed in the receiving groove. The driving motor 20 is accommodated in the receiving groove, and the driving spindle 30 is accommodated in the placement groove. Two stop surfaces 401 are formed on the inner wall surface of the placement groove.

[0099] In some embodiments, the rotation axis of the driving main shaft 30 and the rotation axis of the transmission connection shaft portion 11a are arranged in parallel, so that the transmission connection shaft portion 11a revolves around the driving main shaft 30, and the transmission connection shaft portion 11a rotates itself, and the motion stability of the driven structure 10 is better. In addition, the rotation axes of at least two of the rotating shaft portions 12a are arranged in parallel, which also facilitates the corresponding at least two blades 300 to move synchronously.

[0100] In the design of realizing the two blades 300 opening at different angles, in some embodiments, it is necessary to set the rotation axis of the driving main shaft 30 and the rotation axis of the rotating shaft portion 12a to a certain angle to facilitate the interaction and torque transmission between the various components.

[0101] Specifically, see Figure 6 There is an angle between the rotation axis of the driving spindle 30 and the rotation axis of the rotating shaft portion 12a, which is the angle Figure 6 The angle θ in Figure 6 It can be seen that θ is a smaller angle.

[0102] In the above structure, when the driving spindle 30 drives the driven structure 10 , the transmission connection part 11 not only rotates, but also moves along the axial direction of the driving spindle 30 .

[0103] Specifically, the length of the transmission connection shaft portion 11a is greater than the width of the mounting groove 3011 along the axial direction of the driving main shaft 30, so that the transmission connection shaft portion 11a can move in the mounting groove 3011 along the axial direction of the driving main shaft 30. Therefore, the transmission connection shaft portion 11a can have space to move axially relative to the mounting groove 3011.

[0104] It can be understood that in the embodiment where a second limiting protrusion 123 is provided at the end of the transmission connection shaft portion 11a, the transmission structure includes a transmission disc portion, and the transmission connection shaft portion 11a is protruded on the transmission disc portion, that is, the distance between the second limiting protrusion 123 and the transmission disc portion is greater than the width of the mounting groove 3011 along the axial direction of the drive spindle 30.

[0105] In addition, it should be noted that the rotation axis of the driving spindle 30 and the corresponding rotation axis of the rotating shaft portion 12a are two axes in space, and the two axes may be arranged to intersect or not to intersect.

[0106] In one embodiment, the rotation axis of the driving spindle 30 and the corresponding rotation axis of the rotating shaft portion 12a can construct a plane. In the constructed plane, the rotation axis of the driving spindle 30 and the corresponding rotation axis of the rotating shaft portion 12a are intersectingly arranged, and the angle θ can be the angle between two straight lines in the plane.

A plurality of blades 300 are arranged in a one-to-one correspondence with the rotating mounting parts 12 in the mounting structure group. Each of the blades 300 is provided with a rotating connection part 301 and a driving connection part 302, and the rotating connection part 301 of each blade 300 is rotatably installed at the edge of the grille opening.

[0110] The housing of the driving motor 20 in the driving mechanism 100 is disposed on the grid frame, and each of the rotating mounting parts 12 in the driving mechanism 100 is rotatably mounted on the corresponding driving connection part 302 .

[0111] In the air intake grille module 1000, the drive motor 20 outputs torque to the drive shaft 30, and the eccentric convex portion 301 of the drive shaft 30 transmits the torque to the driven structure 10, thereby realizing the rotation of at least two blades 300 in a blade group, thereby realizing the simultaneous opening or closing of the grille opening, and the stability of the mechanism operation is better.

[0112] It can be understood that two grille openings are provided on the grille frame, and two blades 300 form a blade group, and two blade groups are provided, and are provided corresponding to the two grille openings. In addition, two transmission structures are provided, two drive spindles 30 are provided, and one drive motor 20 is provided, so that the torque can be transmitted to the two drive spindles 30 respectively through one drive motor 20, and then the two driven structures 10 are driven to move, thereby realizing the synchronous rotation of the four blades 300 in the two blade groups.
