Description
Technical Field
[0001] This utility model belongs to the technical field of active air intake grilles for vehicles, and in particular relates to a blade connection structure, an active air intake grille, and a vehicle. Background Technology
[0002] An active grille shutter is an important component of a vehicle's thermal management system. By adjusting the opening and closing of the grille blades, it precisely controls the amount of air entering the engine compartment and the vehicle's aerodynamic drag. In traditional gasoline-powered vehicles, this active grille shutter helps reduce wind resistance, thereby improving fuel economy; for new energy vehicles, it can effectively reduce energy consumption and extend driving range.
[0003] In existing active grille designs, the grille blades are typically controlled by a connecting rod. Specifically, a rod on the connecting rod is inserted laterally through a mounting hole on the grille blade, and the connection between the rod and the edge of the mounting hole is achieved through abutment and restraint. Obviously, in this assembly process, the operator needs to locate the mounting holes on the grille blades, which increases production time and cycle time, leading to higher costs. Furthermore, because the connecting rod and grille blades are fixed on one side by a protruding buckle, uneven force distribution occurs during transmission. This makes the connecting rod prone to twisting and deformation when controlling the rotation of multiple grille blades, causing asynchronous movement and incomplete closure among the blades. In severe cases, it can even cause the grille blades to jam and fail to open properly. Utility Model Content
[0004] In view of this, it is necessary to provide a blade connection structure, an active air intake grille, and a vehicle for solving the above-mentioned technical problems.
[0005] A blade connection structure, the blade connection structure comprising: A grid blade includes a blade body, a drive shaft, and a limiting protrusion. The drive shaft is disposed at one end of the blade body and connected to the blade body. The limiting protrusion is disposed on the outer peripheral wall of the drive shaft and protrudes radially along the drive shaft. The connecting rod has a connecting joint, which includes multiple snap fasteners. The multiple snap fasteners are spaced apart along the length direction of the grid blades. The multiple snap fasteners can simultaneously engage the drive shaft so that the connecting joint is connected to the grid blades in a transmission connection. The limiting protrusion is located between two adjacent buckles, and in the length direction of the grille blade, the limiting protrusion abuts against and limits one of the two adjacent buckles.
[0006] Understandably, using multiple clips to simultaneously engage the drive shaft allows for linear installation between the connecting joint on the connecting rod and the drive shaft on the grille blades. This design simplifies the assembly process between the connecting rod and the grille blades, allowing operators to complete the connection without additional actions, thus reducing production costs. Furthermore, the abutment between the limiting protrusion and adjacent clips ensures stable lateral fixation between the connecting joint and the drive shaft, significantly improving the uniformity of force distribution when the connecting rod drives the grille blades to rotate. This effectively prevents deformation of the connecting rod due to uneven torque, reducing the risk of grille blade jamming and inability to open, and ensuring higher synchronization among multiple grille blades during rotation.
[0007] In one embodiment, the number of the buckles is configured to be two, and the two buckles are a first buckle and a second buckle, with a receiving groove formed between the first buckle and the second buckle; When the first buckle and the second buckle are respectively engaged with the drive shaft, the limiting protrusion is accommodated in the accommodating groove, and the limiting protrusion abuts against the first buckle in the length direction of the grille blade.
[0008] In one embodiment, the first buckle has a slot, through which the first buckle can engage the drive shaft.
[0009] In one embodiment, the second buckle has a snap-fit hole, and in response to an external force, the second buckle can elastically deform in the longitudinal direction of the grille blade away from the drive shaft, so that the drive shaft is snapped into the snap-fit hole.
[0010] In one embodiment, the end of the second latch facing the drive shaft has a guide slope; In response to an external force, the second latch can push the drive shaft through the guide ramp to guide the second latch to undergo elastic deformation away from the drive shaft in the length direction of the grid blade.
[0011] Understandably, using a guide ramp to guide the elastic deformation of the second snap fastener can improve the smoothness and reliability of the assembly process of the second snap fastener on the drive shaft, ensuring that the second snap fastener engages with the drive shaft.
[0012] In one embodiment, the second buckle is further provided with a hollow groove, which is connected to the snap-fit hole.
[0013] It is understandable that by creating a hollowed-out groove on the second buckle, the amount of material used in the production of the second buckle can be reduced, which is conducive to the elastic deformation of the second buckle.
[0014] In one embodiment, in the vehicle height direction, the drive shaft abuts and limits the first latch upwards, and the drive shaft abuts and limits the second latch downwards.
[0015] It is understandable that the first and second latches are used to limit the upper and lower positions of the drive shaft. This prevents the drive shaft from moving up and down during the rotation of the grid blades by the connecting rod, and helps to ensure the uniformity of the force when the connecting rod drives the grid blades to rotate.
[0016] In one embodiment, the limiting protrusion is annular.
[0017] This application also provides an active air intake grille, including the blade connection structure described above.
[0018] This application provides a vehicle including the blade connection structure described above; Alternatively, it could include the active air intake grille described above.
[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The blade connection structure, active air intake grille, and vehicle claimed in this application employ a method of simultaneously engaging the drive shaft with multiple clips. This allows for linear installation between the connecting joint on the connecting rod and the drive shaft on the grille blades. This design simplifies the assembly process between the connecting rod and the grille blades, allowing operators to complete the connection without additional actions, thus reducing production costs. Furthermore, the abutment and limiting between the limiting protrusion and adjacent clips ensures stable lateral fixation between the connecting joint and the drive shaft. This significantly improves the uniformity of force distribution when the connecting rod drives the grille blades to rotate. This effectively prevents deformation of the connecting rod due to uneven torque, reducing the risk of grille blade jamming and inability to open, and ensuring higher synchronization among multiple grille blades during rotation.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0033] like Figure 8 As shown, the blade connection structure 100 claimed in this application specifically refers to the assembly connection between the grille blade 10 and the connecting rod 20 in the active air intake grille 1000, so that when the active air intake grille 1000 is working, the grille blade 10 can be opened or closed under the drive of the connecting rod 20.
[0034] like Figures 1 to 8 As shown, the blade connection structure 100 claimed in this application includes a grid blade 10 and a connecting rod 20. The grid blade 10 includes a blade body 11, a drive shaft 12, and a limiting protrusion 13. The drive shaft 12 is disposed at one end of the blade body 11 and connected to the blade body 11. The limiting protrusion 13 is disposed on the outer peripheral wall of the drive shaft 12 and protrudes radially along the drive shaft 12. The connecting rod 20 has a connecting joint 21, which includes multiple latches 210. The multiple latches 210 are spaced apart in the length direction L of the grid blade 10. The multiple latches 210 can simultaneously engage the drive shaft 12 so that the connecting joint 21 is connected to the grid blade 10 in a transmission manner. The limiting protrusion 13 is located between two adjacent latches 210, and in the length direction L of the grid blade 10, the limiting protrusion 13 abuts against and limits one of the two adjacent latches 210 respectively. It is understood that the grid blades 10 and the connecting rod 20 are connected by multiple snap fasteners 210 simultaneously engaging the drive shaft 12, allowing the connecting joint 21 on the connecting rod 20 to be vertically installed onto the drive shaft 12. This simplifies the assembly process between the connecting rod 20 and the grid blades 10, allowing operators to complete the connection without additional actions, thus reducing production costs. Furthermore, the abutment and limiting between the limiting protrusion 13 and the adjacent snap fasteners 210 ensures a stable two-sided fixation between the connecting joint 21 and the drive shaft 12, significantly improving the uniformity of force distribution when the connecting rod 20 drives the grid blades 10 to rotate. This effectively prevents deformation of the connecting rod 20 due to uneven torque, reducing the risk of the grid blades 10 jamming and failing to open, and ensuring higher synchronization among the multiple grid blades 10 during rotation.
[0035] It should be noted that the drive shaft 12 of the above-mentioned grid blade 10 extends along the length direction L of the grid blade 10. Specifically, it can be integrally injection molded with the blade body 11. Furthermore, the drive shaft 12 is eccentrically set relative to the rotation center line of the grid blade 10, so that the connecting rod 20 can drive the grid blade 10 to rotate through the cooperation between the connecting joint 21 and the drive shaft 12, thereby achieving the purpose of controlling the opening / closing of the grid blade 10.
[0036] like Figure 8 As shown, in one embodiment, the number of grille blades 10 is set to multiple; correspondingly, the number of connecting joints 21 on the connecting rod 20 is also set to multiple, with each connecting joint 21 corresponding to one of the grille blades 10, and the connecting rod 20 can be driven to the corresponding grille blade 10 through the connecting joint 21. That is to say, the connecting rod 20 can simultaneously drive multiple grille blades 10 to rotate, in order to meet the usage requirements of the active air intake grille 1000.
[0037] Here, the number of grille blades 10 can be set to two, three, four, or even more, depending on the specific needs of the active air intake grille 1000. This will not be elaborated on here.
[0038] like Figure 1 As shown, in one embodiment, the limiting protrusion 13 is annular. Specifically, the arc angle of the limiting protrusion 13 can be set to a semi-circular ring structure of 180°. Furthermore, the limiting protrusion 13 is integrally connected to the drive shaft 12 to satisfy the requirement that the limiting protrusion 13 abuts and limits one of the two adjacent latches 210. It can be understood that in other embodiments, the arc angle corresponding to the limiting protrusion 13 can also be 160°, 170°, 200°, 280°, or 360°.
[0039] like Figures 1 to 7 As shown, in one embodiment, the number of buckles 210 is configured to be two, and the two buckles 210 are respectively the first buckle 211 and the second buckle 212. A receiving groove 213 is formed between the first buckle 211 and the second buckle 212. When the first buckle 211 and the second buckle 212 are respectively engaged with the drive shaft 12, the limiting protrusion 13 is accommodated in the receiving groove 213, and the limiting protrusion 13 is set against the first buckle 211 in the length direction of the grille blade 10.
[0040] The first buckle 211 has a groove 2111 formed thereon, and the first buckle 211 can engage the drive shaft 12 through the groove 2111; and the second buckle 212 has a hole 2122, and in response to an external force, the second buckle 212 can elastically deform in the length direction of the grid blade 10 away from the drive shaft 12, so that the drive shaft 12 is engaged in the hole 2122.
[0041] As can be seen from the above, during the process of aligning the first buckle 211 and the second buckle 212 of the connecting joint 21 on the connecting rod 20 with the drive shaft 12 and inserting them, the second buckle 212 will first undergo elastic deformation under the obstruction of the drive shaft 12, and the slot 2111 on the first buckle 211 will be engaged with the drive shaft 12. When the bottom 2112 of the slot 2111 on the first buckle 211 contacts the drive shaft 12 and abuts against the limit, the second buckle 212 just loses the action of the drive shaft 12 and rebounds, so that the second buckle 212 is engaged with the drive shaft 12. This means that the connecting rod 20 in this embodiment can use the engagement between the first buckle 211 and the drive shaft 12 to prevent downward movement, and use the engagement between the second buckle 212 and the drive shaft 12 to prevent upward transmission, thereby ensuring that the connecting rod 20 is subjected to uniform force during the rotation of the grid blades 10.
[0042] like Figure 4 , Figure 7 As shown, in one embodiment, the second snap fastener 212 has a guide slope 2121 at one end facing the drive shaft 12. In response to an external force, the second snap fastener 212 can push the drive shaft 12 through the guide slope 2121, guiding the second snap fastener 212 to elastically deform away from the drive shaft 12 along the length of the grille blades 10. That is, during the process of aligning and inserting the connector 21 with the drive shaft 12, the second snap fastener 212 pushes the drive shaft 12 through the guide slope 2121. Utilizing action and reaction forces, the drive shaft 12 pushes the guide slope 2121 in the opposite direction, guiding the second snap fastener 212 to elastically deform. This improves the smoothness and reliability of the assembly process of the second snap fastener 212 on the drive shaft 12, ensuring that the second snap fastener 212 engages with the drive shaft 12.
[0043] Here, as Figure 2 As shown, the second buckle 212 also has a hollowed-out groove 2123, which is connected to the snap-fit hole 2122. This reduces the amount of material used when making the second buckle 212, thus facilitating the elastic deformation of the second buckle 212.
[0044] like Figure 7 As shown, in the vehicle height direction, the drive shaft 12 is positioned upwards against the first latch 211 and downwards against the second latch 212. This prevents the drive shaft 12 from moving up and down during the rotation of the grille blades 10 by the connecting rod 20, and promotes the uniformity of the force applied when the connecting rod 20 rotates the grille blades 10.
[0045] like Figure 1 , Figure 5As shown, in one embodiment, the connecting rod 20 further includes a connecting rod body 22. The extension directions of the first latch 211 and the second latch 212 of the connecting joint 21 are consistent with the extension direction of the connecting rod body 22. Obviously, compared with the existing connecting rod structure, the connecting rod 20 structure of this embodiment eliminates the crossbar of the existing connecting rod structure, which can reduce the amount of material used in the connecting rod 20 and reduce the manufacturing cost of the connecting rod 20.
[0046] like Figure 8 As shown, this application also provides an active air intake grille 1000, including the blade connection structure 100 described above.
[0047] like Figure 8 As shown, in one embodiment, the active air intake grille 1000 further includes a frame 200, a motor 300, and a connecting shaft 400. The motor 300 is connected to the connecting rod 20 via the connecting shaft 400. Each connecting rod 20 is simultaneously connected to three grille blades 10. The three grille blades 10 are sequentially and spaced apart on the frame 200, so that when the active air intake grille 1000 is working, the motor 300 can simultaneously drive the three grille blades 10 to rotate on the frame 200 via the connecting rod 20, thereby achieving the purpose of controlling the opening / closing of the air intake channel of the active air intake grille 1000.
[0048] Alternatively, this application provides a vehicle including the blade connection structure 100 described above; or, including the active air intake grille 1000 described above.
[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
