[0037] The present application provides a blade assembly, a grille assembly and a car. In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figure 1 As shown, the blade assembly 100 includes a blade 101 and a blade guide rail 102 .

[0039] like Figure 2 As shown, the blade 101 is provided with a matching portion 1012. Specifically, the blade 101 has a sheet-shaped blade body 1011, the end of the blade body 1011 is folded to form a flange plate, and the matching portion 1012 is provided at the end flange plate of the blade body 1011.

[0040] like Figure 3 As shown, the blade guide rail 102 is provided with a guide portion 1021. The mating portion 1012 of the blade 101 is guided and mated with the guide portion 1021 of the blade guide rail 102 and can slide along the length direction of the guide portion 1021. The guide portion 1021 of the blade guide rail 102 has a first guide section 1021a and a second guide section 1021b. The length of the first guide section 1021a smoothly transitions to one end and connects to the length of the second guide section 1021b smoothly transitioning to one end. The length of the first guide section 1021a toward the centerline (dashed line in the figure) and the length of the second guide section 1021b toward the centerline (dashed line in the figure) form an angle with each other.

[0041] Since the length of the first guide section 1021a and the length of the second guide section 1021b form an angle with each other, when the matching portion 1012 slides from the first guide section 1021a to the second guide section 1021b, the blade 101 will move from the first guide section 1021a to the second guide section 1021b. Figure 5 The angle shown is flipped to Figure 4 Similarly, when the matching portion 1012 slides from the second guide portion 1021b to the first guide portion 1021a, the blade 101 will move from Figure 4 The angle shown is flipped to Figure 5 Angle shown.

[0042] In short, the blade 101 of the blade assembly 100 can slide and flip relative to the blade guide rail 102 .

[0043] like Figure 12 and Figure 13 As shown, the blade assembly 100 can be mounted on a grille body 200 to form a grille assembly. The grille body 200 has an opening 200a, and the opening 200a of the grille body 200 is opened and closed by sliding and flipping the blades 101.

[0044] like Figure 14 As shown, the blade 101 can be installed close to the grille body 200 , so that the blade 101 is close to the grille body 200 when the opening 200 a of the grille body 200 is closed by the blade 101 .

[0045] When the opening 200a of the grille body 200 is opened, the blade 101 slides along the grille body 200, gradually sliding from the second guide section 1021b to the first guide section 1021a, and flips from an angle substantially perpendicular to the air flow to an angle substantially parallel to the air flow, and finally from the second guide section 1021b to the first guide section 1021a. Figure 14 Slide the position shown to flip to Figure 15 Position shown.

[0046] During the process of closing the opening 200a of the grille body 200, the blade 101 gradually slides from the first guide section 1021a to the second guide section 1021b, and turns from an angle substantially parallel to the air flow to an angle substantially perpendicular to the air flow, and finally turns from Figure 15 Slide the position shown to flip to Figure 14 Position shown.

[0047] As can be seen from the above description, in the above grille composition, when the blade 101 is installed closely against the grille body 200 , the blade 101 can still smoothly open and close the opening 200 a of the grille body 200 without being interfered by the grille body 200 .

[0048] The air intake grille of the automobile can adopt the above-mentioned grille composition. Since the blades 101 are installed closely against the grille body 200, the above-mentioned grille composition can maintain the streamline of the automobile's outer surface to the maximum extent, thereby helping to reduce the automobile's running resistance.

[0049] In the illustrated embodiment, Figure 2 As shown, the mating portion 1012 includes a first mating rod 1012a and a second mating rod 1012b, and the length of the first mating rod 1012a is slightly longer than that of the second mating rod 1012b. Figure 3As shown, the guide portion 1021 is a long guide hole, one section of the long guide hole forms a first guide section 1021a, and the other section forms a second guide section 1021b. Figure 3 As shown, both the first mating rod 1012a and the second mating rod 1012b extend from one side of the guide slot into the slot. One end of the first mating rod 1012a extends from the other side of the guide slot and connects to the transmission mechanism (if provided). It should be noted that in actual implementation, the structure of the mating portion 1012 and the structure of the guide portion 1021 are not limited to mating rods and guide slots; any structure that can guide, mate, and slide relative to each other is acceptable.

[0050] Specifically, such as Figure 3 As shown, the blade guide rail 102 is further provided with a fixing portion 1022 , so as to achieve position fixation through the fixing portion 1022 . Figure 3 In the embodiment shown, the fixing portion 1022 is a perforated plate. When used, the fastener passes through the perforated plate and is fastened to the substrate (eg, the grille body 200). Of course, the fixing portion 1022 is not limited to a perforated plate, as long as it is a structure that is convenient for connecting the fastener.

[0051] like Figure 1 As shown, the blade assembly 100 may also optionally include a power element 103 and a transmission mechanism 104. The power element 103 may be a motor, which is easy to control and compact. The transmission mechanism 104 is connected to the power element 103 and also to the mating portion 1012 of the blade 101, thereby transmitting power from the power element 103 to the mating portion 1012 of the blade 101, thereby driving the mating portion 1012 to slide along the guide portion 1021.

[0052] like Figure 1 As shown, a mating portion 1012 can be provided at both ends of the length of the blade 101, and a guide portion 1021 and a transmission mechanism 104 can be provided at both ends of the length of the blade 101. The mating portions 1012 at both ends of the blade 101 are respectively mated with the guide portion 1021 at the same end and are respectively connected to the transmission mechanism 104 at the same end. The transmission mechanisms 104 at both ends of the blade 101 are connected via a linkage shaft 105. This design ensures synchronization between the two ends of the blade 101, thereby preventing problems such as the blade 101 being twisted and damaged due to a lack of synchronization at both ends, and the blade 101 being unable to tightly close the opening 200a of the grille body 200.

[0053] Figure 1 In the embodiment shown, the linkage shaft 105 is connected to the transmission mechanism 104 at both ends of the blade 101, and the linkage shaft 105 is also provided with a spline structure 1052 (see Figure 7), is connected to the spline groove on the power element 103 through the spline structure 1052, thereby not only playing a linkage role, but also serving as a connecting shaft, connecting the transmission mechanism 104 and the power element 103, so that the power of the power element 103 can be transmitted to the transmission mechanism 104 through the linkage shaft 105, and then transmitted to the matching part 1012 of the blade 101 through the transmission mechanism 104.

[0054] like Figure 1 As shown, the blade assembly 100 is provided with a mounting seat 106. The linkage shaft 105 is inserted into a seat hole 1063 of the mounting seat 106 and is rotatable within the seat hole 1063 of the mounting seat 106. During use, the mounting seat 106 is fixed to a substrate (e.g., the grille body 200) to define the radial position of the linkage shaft 105. A single linkage shaft 105 can be inserted into the seat holes 1063 of multiple mounting seats 106 (two in the figure), thereby achieving better positioning.

[0055] like Figure 1 As shown, a limiting structure 1051 can be provided on the outer periphery of the linkage shaft 105. The limiting structure 1051 is restrained by the mounting seat 106 to limit the axial movement of the linkage shaft 105 in the seat hole 1063 of the mounting seat 106, thereby limiting the axial position of the linkage shaft 105. In the embodiment shown in the figure, the limiting structure 1051 is an annular protrusion formed on the outer periphery of the linkage shaft 105 (see Figure 7 ), the annular protrusion conflicts with the opening position of one end of the seat hole 1063 of the mounting seat 106. Of course, the limiting structure 1051 is not limited to the annular protrusion, as long as it can conflict with the structure of the mounting seat 106 along the axial direction.

[0056] like Figure 1 As shown, the blade assembly 100 can be provided with at least one set of blade groups, each set of blade groups including a plurality of blades substantially along the width direction of the blade 101 ( Figure 1 A plurality of blades 101 are sequentially arranged in the vertical direction (in the middle and the lower direction), and each blade group is roughly along the length direction of the blade 101 ( Figure 1 Set in sequence (center, left, and right directions). Figure 1 In the embodiment shown, two blade groups are provided, each blade group having three blades 101 .

[0057] like Figure 1 As shown, the matching parts 1012 at the same end of each blade 101 of the same blade group can be driven by the same transmission mechanism 104. Figure 1 Taking the blade group on the left side as an example, the left end matching parts 1012 of the three blades 101 of the blade group are driven by the same transmission mechanism 104, and the right end matching parts 1012 of the three blades 101 are driven by the same transmission mechanism 104. With this design, the blades 101 of the same blade group have better synchronization.

[0058] like Figure 1 As shown, the transmission mechanism 104 can be a crank slider assembly, including a crank 1041, a connecting rod 1042, and a slider 1043. The crank 1041, the connecting rod 1042, and the slider 1043 are rotatably connected in sequence, and the mating portion 1012 is rotatably connected to the slider 1043. The slider 1043 can slide along the length of the guide portion 1021 under the guidance of the mating portion 1012 and the guide portion 1021.

[0059] In the illustrated embodiment, Figure 7-Figure 9 As shown, one end of the crank 1041 is fixedly connected to the linkage shaft 105 (the crank 1041 and the linkage shaft 105 are an integral structure in the figure), the connecting post A at the other end of the crank 1041 is rotatably connected to the connecting hole B at one end of the connecting rod 1042, the connecting hole B at the other end of the connecting rod 1042 is rotatably connected to the connecting post A at one end of the slider 1043, and the first engaging rod 1012a of the engaging portion 1012, one end of which extends out of the long guide hole, is rotatably connected to the socket 1043a of the slider 1043. The power of the power element 103 is transmitted to the linkage shaft 105 through the spline structure 1052, driving the linkage shaft 105 to rotate about its own central axis, thereby driving the crank 1041 to rotate, and then driving the connecting rod 1042 to rotate, and then driving the slider 1043 and the engaging portion 1012 to slide along the length direction of the guide portion 1021.

[0060] like Figure 6 As shown, the adjacent ends of two adjacent blade groups can be connected to a transmission mechanism 104 respectively, and the sliders 1043 of the two transmission mechanisms 104 connected to the adjacent ends of the two adjacent blade groups can be integrated together. Figure 10 As shown, the sliders 1043 of the two transmission mechanisms 104 connected to the adjacent ends of the two adjacent blade groups are integrated together through connecting ribs, so that the synchronization of different blade groups can be improved.

[0061] like Figure 11 As shown, in order to facilitate the assembly of the linkage shaft 105 and the mounting seat 106, the mounting seat 106 can be provided with a seat body 1061 and a seat cover 1062. The seat cover 1062 can be detachably mounted on the seat body 1061. The semicircular grooves on the seat cover 1062 and the seat body 1061 are aligned with each other to form a seat hole 1063.

[0062] The principles and implementation methods of the present application have been described above using specific examples. The description of the above embodiments is only intended to help understand the method and core concept of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, various improvements and modifications may be made to the present application, and such improvements and modifications also fall within the scope of protection of the claims of the present application.
