[0053] During the vehicle development process, in order to improve the performance of the vehicle's air conditioning system, the grille of the air conditioning radiator is usually designed from a passive air intake grille to an active air intake grille, thereby improving the heat dissipation effect and optimizing the air conditioning performance.

[0054] An air intake grille module is an active air intake component, which typically includes a grille frame with a grille opening on the grille frame. A blade is rotatably mounted at the edge of the grille opening. For a single grille opening, there can be multiple blades, which rotate in conjunction to open or close the grille opening.

[0055] In some active air intake grilles, motors and linkage mechanisms can be used to rotate the blades. Commonly, a single motor can be used to drive multiple linkage mechanisms to drive multiple blades; or a single motor can be used, and linkage mechanisms can be set between the blades to achieve the rotation of multiple blades. The above-mentioned structures connected to the blades are relatively complex and need to be optimized.

[0056] The main purpose of this utility model is to propose a blade rotation connection structure, a drive mechanism, an air intake grille module, and a vehicle, aiming to optimize the existing structure connected to the blade.

[0057] Please see Figure 1 The present invention also proposes a blade rotation connection structure 10, which includes a blade group and a driven structure 12. The blade group includes at least two blades 11, and each blade 11 has a rotation connection part 111 and a drive connection part 112 at both ends. The rotation connection part 111 is used to be rotatably installed at the edge of the grille opening 201.

[0058] A transmission connection portion 121 and a rotating mounting portion 122 are formed on the driven structure 12. The transmission connection portion 121 is used to drive the drive motor 20 of the air intake grille module 1000. The rotating mounting portion 122 and the drive connection portion 112 are arranged in a one-to-one correspondence. The rotating mounting portion 122 and the corresponding drive connection portion 112 are rotatably connected.

[0059] In the technical solution of this utility model, each blade 11 has a rotating connection part 111 and a driving connection part 112 at both ends. The rotating connection part 111 is rotatably mounted at the edge of the grille opening 201. A transmission connection part 121 and a rotating mounting part 122 are formed on the driven structure 12. The transmission connection part 121 is used to drive the drive motor 20 of the air intake grille module 1000. The rotating mounting part 122 and the driving connection part 112 are arranged in a one-to-one correspondence. The rotating mounting part 122 and the corresponding driving connection part 112 are rotatably connected. When the torque is transmitted to the transmission connection part 121 to rotate, the rotating mounting part 122 rotates, thereby driving at least two blades 11 in one blade group to rotate. Multiple blades 11 in one blade group can rotate simultaneously through the driven structure 12. The structure is simple and the transmission performance is optimized.

[0060] It is understood that in one blade group, the number of blades 11 can be two, three or more. The more blades there are, the higher the complexity of achieving simultaneous rotation of multiple blades 11 through one driven structure 12.

[0061] In one embodiment, two blades 11 are provided in one blade group. The two blades 11 are arranged in the vertical direction relative to the vehicle. The two blades 11 include an upper blade 11 and a lower blade 11. The upper blade 11 is arranged in the upper part of the grille opening 201, and the lower blade 11 is arranged in the lower part of the grille opening 201. The two blades 11 rotate simultaneously to open and close the grille opening 201 together.

[0062] The rotating mounting portion 122 and the driving connection portion 112 are provided in a one-to-one correspondence. The number of driving connection portions 112 is the same as the number of rotating mounting portions 122. Correspondingly, the number of blades 11 is the same as the number of rotating mounting portions 122.

[0063] Furthermore, the arrangement of the rotating connection 111 and the driving connection 112 directly determines whether the driven structure 12 can drive the two blades 11 to rotate. In some extreme embodiments, the rotating connection 111 and the driving connection 112 can be coaxially arranged; in other embodiments, the rotating connection 111 and the driving connection 112 are off-axis arranged, that is, their rotation center lines do not coincide. When the driven structure 12 rotates, the driving connection 112 of the two blades 11 can rotate around the rotating connection 111 of the blade 11, thereby driving each blade 11 to rotate.

[0064] In some embodiments, for a single blade 11, two rotating connection portions 111 are provided, respectively located at both ends of the blade 11 and coaxially arranged, thereby improving the rotational stability of the blade 11.

[0065] A transmission connection portion 121 and a plurality of rotating mounting portions 122 are formed on the driven structure 12. The driven structure 12 can be integrally molded. This configuration is simple to form and has a low cost compared to machining.

[0066] In some embodiments where the driven structure 12 is made of plastic, the driven structure 12 may be integrally injection molded.

[0067] The drive connection part 112 and the rotating mounting part 122 are rotatably engaged. In the technical solution of this utility model, the specific engagement method of the drive connection part 112 and the rotating mounting part 122 is not limited. For example, the rotation can be achieved by means of a hinge; or by means of a gear structure connection, etc.

[0068] In some embodiments, one of the drive connection portion 112 and the rotating mounting portion 122 is a hole portion and the other is a shaft portion, wherein the shaft portion is rotatably mounted in the hole portion to achieve a rotating connection.

[0069] In some embodiments, the drive connection portion 112 is configured as a drive connection hole portion, and correspondingly, the rotating mounting portion 122 is configured as a hinge shaft portion. The hinge shaft portion is rotatably mounted in the drive connection hole portion, that is, the rotating mounting portion 122 on the driven structure 12 is configured as a hinge shaft portion, which makes it easy to demold during the integral molding of the driven structure 12 and facilitates manufacturing.

[0070] The transmission connection part 121 can be configured as either a hole or a shaft. In some embodiments, the transmission connection part 121 is configured as a transmission connection shaft, which is easy to demold during the integral molding of the driven structure 12 and facilitates manufacturing.

[0071] In view of the above structure, both the transmission connection part 121 and the rotating mounting part 122 are set as shaft parts, which makes it easy to demold during the integral molding of the driven structure 12 and facilitates manufacturing.

[0072] The rotating connection part 111 can be configured as either a hole or a shaft. In some embodiments, the rotating connection part 111 is configured as a rotating connection shaft to be rotatably mounted with the mounting hole provided on the grid frame 200. This configuration facilitates the installation of the blade 11.

[0073] The driven structure 12 includes a driven body with two opposite sides. The rotating mounting part 122 and the transmission connection part 121 can be mounted on the same side of the driven body, or the transmission connection part 121 and the rotating mounting part 122 can be mounted on two sides of the driven body.

[0074] In some embodiments, the rotating mounting portion 122 and the transmission connection portion 121 are respectively disposed on two sides, that is, the hinge shaft portion and the transmission connection shaft portion are disposed on opposite sides of the driven body. On the one hand, this facilitates the placement of the drive motor 20; on the other hand, it makes it easy to demold during the integral molding of the driven structure 12, which is convenient for manufacturing.

[0075] In some embodiments, the rotating mounting portion 122 and the transmission connection portion 121 are respectively disposed on the same side, that is, the hinge shaft portion and the transmission connection shaft portion are disposed on the same side of the driven body, which can save axial installation space.

[0076] In addition, it should be noted that the arrangement of the plurality of rotating mounting parts 122 on the driven body is not limited. The plurality of rotating mounting parts 122 can be arranged on the same side of the driven body or on opposite sides of the driven body.

[0077] In some embodiments, the opening angles of the two blades 11 in one blade group are synchronized, that is, the relative rotation radii between the rotation center of the transmission connection 121 and the rotation centers formed on the two rotation mounting portions 122 are set to be the same; in other embodiments, the relative rotation radii between the rotation center of the transmission connection 121 and the rotation centers formed on the two rotation mounting portions 122 are set to be different, so that the two blades 11 in one blade group open at different angles.

[0078] Alternatively, some limiting structures can be provided on the blade 11 to limit the opening angle of the blade 11, such as setting a limiting baffle, etc.; in some embodiments, a limiting structure can be provided on the driven structure 12 and a matching structure can be provided on the grid frame 200 to limit the rotation stroke of the driven structure 12, thereby limiting the opening angle of the blade 11.

[0079] Please see Figure 2 and Figure 5 The present invention also proposes a blade rotation drive mechanism 100, which includes a drive motor 20 and a blade rotation connection structure 10, wherein the drive motor 20 drives the transmission connection part 121 connected to the blade rotation connection structure 10.

[0080] The specific structure of the blade rotation connection structure 10 is as described in all the above embodiments. Since the blade rotation drive mechanism 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0081] The number of blade rotation connection structures 10 is not limited; there can be one, two, or more.

[0082] In some embodiments, at least two blade rotation connection structures 10 are provided, and correspondingly, at least two blade groups are provided. The opening and closing of the blades 11 in the two blade groups can be driven by one drive motor 20, which reduces the number of drive motors 20 and simplifies the structure.

[0083] There are various ways to transmit the output torque from the drive motor 20 to at least two of the blade rotation connection structures 10, such as through a multi-link system or a gear transmission system.

[0084] In some embodiments, the blade rotation drive mechanism 100 further includes a drive body, which is driven and connected to the drive motor 20. An eccentric protrusion 301a is formed on the drive body, and the eccentric protrusion 301a is correspondingly arranged with the transmission connection portion 121 of the blade rotation connection structure 10. The eccentric protrusion 301a is rotatably connected to the corresponding transmission connection portion 121, so that the transmission connection portion 121 rotates eccentrically relative to the output shaft of the drive motor 20. Multiple eccentric protrusions 301a are formed on the drive body to transmit the torque of the drive motor 20 to the multiple eccentric protrusions 301a, thereby driving the multiple transmission connection portions 121 to rotate eccentrically. In the transmission system, the number of parts is relatively small, which improves the stability of the mechanism operation.

[0085] In some embodiments, the drive body can be configured as a long shaft, with at least two eccentric protrusions 301a at the end of the long shaft, a first transmission gear on the long shaft, and a second transmission gear on the output shaft of the drive motor 20. The first transmission gear and the second transmission gear mesh and transmit power to drive the drive body, thereby driving the at least two eccentric protrusions 301a to rotate eccentrically.

[0086] In some embodiments, the drive body can be configured as multiple shafts. Specifically, the drive body includes a drive spindle 30, one end of which is connected to the drive motor 20, and the other end forms the eccentric protrusion 301a. The drive spindle 30 and the transmission connection portion 121 of the blade rotation connection structure 10 are arranged in a one-to-one correspondence. That is, the number of eccentric protrusions 301a is the same as the number of drive spindles 30, and multiple drive spindles 30 can be driven by the drive motor 20. For example, a gear transmission system structure can be used.

[0087] In some embodiments, two drive spindles 30 are provided and are respectively located on both sides of the drive motor 20. Two blade rotation connection structures 10 are provided, and the transmission connection part 121 of each blade rotation connection structure 10 is rotatably connected to the eccentric protrusion 301a on the corresponding drive spindle 30.

[0088] The output shaft of the drive motor 20 rotates to drive the two drive shafts 30 to rotate. The two drive shafts 30 transmit torque to the driven structure 12 of the two blade rotation connection structures 10 through the eccentric protrusion 301a, thereby driving the rotation of the two blade groups and realizing the opening and closing of the two grid openings 201 on the grid frame 200. A single motor can realize the rotation of the two blade groups, which is simple in structure and improves the stability of the mechanism operation.

[0089] It is understood that the eccentric protrusion 301a extends from the periphery of the drive spindle 30, and a mounting groove 3011 is provided on the eccentric protrusion 301a. The mounting groove 3011 is provided through the eccentric protrusion 301a, and the transmission connecting shaft is rotatably mounted in the mounting groove 3011.

[0090] A limiting part is also provided at the opening of the mounting groove 3011 to limit the radial runout of the transmission connecting shaft and prevent it from disengaging from the mounting groove 3011.

[0091] When assembling the driven structure 12 and the drive spindle 30, the transmission connection part 121 can be inserted into the mounting groove 3011 from the opening of the mounting groove 3011.

[0092] In addition, by using the cooperation between the mounting groove 3011 and the transmission connection part 121, a limiting protrusion 3012 can also be provided at the end of the transmission connection shaft to limit the relative sliding of the drive spindle 30 and the driven structure 12 along the axial direction.

[0093] In some embodiments, a limiting rib may be provided on the drive shaft 30, and the rotational stroke of the drive shaft 30 may be limited by the limiting rib and the mating part provided on the grid frame 200, thereby limiting the opening angle of the blade 11.

[0094] Please see Figures 3 to 6 The present invention also proposes an air intake grille module 1000, which includes a grille frame 200 and a blade rotation drive mechanism 100.

[0095] The specific structure of the blade rotation drive mechanism 100 is as described in all the above embodiments. Since the air intake grille module 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0096] The housing of the drive motor 20 is disposed on the grid frame 200, and the rotating mounting part 122 of each blade rotating connection structure 10 is respectively hinged to the two driving connection parts 112 of the corresponding at least two blades 11.

[0097] Within the air intake grille module 1000, the drive motor 20 outputs torque to the two drive shafts 30. The eccentric protrusions 301a of the two drive shafts 30 transmit the torque to the two driven structures 12, thereby enabling the rotation of the blades 11 in the two blade groups. This allows the two grille openings 201 to be opened or closed simultaneously, resulting in good synchronization and improved stability of the mechanism.

[0098] The blade 11 is rotatably mounted on the grid frame 200. A rotatable connecting portion 111 is disposed at the end of the blade 11, and the rotatable connecting portion 111 is rotatably mounted at the edge of the grid opening 201 of the grid frame 200. A rotatable mating portion 301b is provided on the grid frame 200 to rotatably engage with the rotatable connecting portion 111. The rotatable connecting portion 111 needs to rotate within the rotatable mating portion 301b. This can be achieved through an interference mounting method; for example, during installation, the blade 11 can be partially deformed to achieve the rotatable mounting of the rotatable connecting portion 111 and the rotatable mating portion 301b.

[0099] In some embodiments, please refer to the following for details. Figure 6 The blade 11 can be installed by setting an external structure. Specifically, the grid frame 200 includes a frame body and a mounting block 300 that can be detachably installed on the frame body. The grid opening 201 is formed on the frame body. A rotating fitting part 301b is provided at the end of the mounting block 300. The rotating connecting part 111 of the blade 11 and the rotating fitting part 301b are rotatably fitted. With this configuration, the mounting block 300 can be installed on the frame body after the rotating connecting part 111 and the rotating fitting part 301b are installed in place, thereby realizing the installation of the blade 11 on the grid frame 200 and reducing the risk of damage to the blade 11 during the installation process.

[0100] In the embodiments of this utility model, the specific way in which the mounting block 300 can be detachably installed on the frame body is not limited. It can be a snap-fit ​​connection, a threaded connection, etc.

[0101] In order to achieve rapid installation and positioning of the mounting block 300, in some embodiments, one of the mounting block 300 and the frame body is provided with a positioning pin 302, and the other is provided with a positioning hole. Through the cooperation of the positioning hole and the positioning pin 302, the mounting block 300 and the grid frame 200 can be quickly positioned, thereby improving installation efficiency.

[0102] In some embodiments, one of the mounting block 300 and the frame body is provided with an adjustment pin 303, and the other is provided with an adjustment mating hole. By cooperating with the adjustment pin 303 and the adjustment mating hole, the mounting block 300 can be quickly installed to a preset position, thereby improving installation efficiency.

[0103] In one of the blade groups, different blades 11 can be provided with different mounting blocks 300. That is, after different blades 11 and their corresponding mounting blocks 300 are assembled, the different mounting blocks 300 are then assembled onto the frame body.

[0104] In some embodiments, a mounting block 300 is provided with two rotating mating parts 301b, and the rotating connecting parts 111 of two blades 11 in a blade group are respectively rotatably mounted on the corresponding rotating mating parts 301b.
