If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0039] In the variable intake grille structure of a vehicle, generally, a scheme is adopted in which a driving motor drives the blades to rotate through a connecting rod transmission mechanism to realize the opening and closing of the intake passage. The connecting rod transmission mechanism usually has a transmission driving part connected to the output shaft of the driving motor. The transmission driving part is driven to rotate by the output shaft of the driving motor, and then other connecting rod structures are driven to move through the transmission driving part, and further drive the blades of the intake grille structure to rotate. However, the end of the transmission driving part away from the driving motor is usually suspended. Under the reaction force of the connecting rod structure in the radial direction, the transmission driving part is prone to bend to a certain extent, resulting in a reduction in its own rotational stability, thereby reducing the transmission stability of the connecting rod transmission mechanism, and it is difficult to ensure the opening and closing precision control of the driving motor for the blades.

[0040] Analyzing the above problems, it can be seen that the fundamental reason for the reduction in the rotational stability of the transmission driving part is that the end of the transmission driving part away from the driving motor is suspended and lacks support. The transmission stability of the connecting rod transmission mechanism can be improved from the perspective of providing support for the end of the transmission driving part.

[0041] In view of this, the present utility model proposes a limit bracket and an intake grille module, aiming to improve the problem of poor transmission stability of the connecting rod transmission structure in the existing variable intake grille structure.

[0042] Among them, Figure 1 is a schematic structural diagram of an embodiment of the limit bracket provided by the utility model; Figure 2Exploded structural schematic diagram of an embodiment of the vehicle front end assembly provided by the present utility model; Figure 3 Structural schematic diagram of a perspective view of the intake grille module provided by the present utility model; Figure 4 Partial structural schematic diagram of another perspective view of the intake grille module provided by the present utility model; Figure 5 Partial structural schematic diagram of a perspective view of the grille frame in the intake grille module provided by the present utility model; Figure 6 Assembly schematic diagram of the drive motor, blade drive part and limit bracket in the intake grille module provided by the present utility model; Figure 7 Assembly schematic diagram of the blade drive part, first connecting rod, second connecting rod, first blade and second blade in the intake grille module provided by the present utility model.

[0043] Please refer to Figure 1 and also refer to Figures 4 to 6 In an embodiment of the present utility model, the limit bracket 1 is used for the intake grille module 100 having a grille frame 3, a drive motor 2 and a blade drive part 4. One end of the blade drive part 4 is drivingly connected to the output shaft of the drive motor 2; the limit bracket 1 has a first connecting part 11 and a second connecting part 12 distributed along a first direction. The first connecting part 11 and the second connecting part 12 are used to connect to different positions of the grille frame 3. A rotating support part 13 is formed on the limit bracket 1 between the first connecting part 11 and the second connecting part 12. The rotating support part 13 is used to support the other end of the blade drive part 4 and can rotate with the other end of the blade drive part 4.

[0044] It should be noted that in this embodiment, the intake grille module 100 belongs to the external application environment of the limit bracket 1 and is not a structural feature of the limit bracket 1 itself. Since one end of the blade drive part 4 is drivingly connected to the output shaft of the drive motor 2, this end is limited by the output shaft of the drive motor.

[0045] After the intake grille module 100 with the limit bracket 1 is correctly installed on the vehicle, the "first direction" is usually the height direction of the vehicle, and the second direction is usually the width direction of the vehicle.

[0046] The "rotating support part 13" is used to support the other end of the blade driving part 4 and can be rotatably matched with the other end of the blade driving part 4. The rotating support part 13 first needs to at least overcome the pressure applied by the other end of the blade driving part 4 to prevent the blade driving part 4 from eccentrically swinging during the process of driving the blades 5 to open and close. There are many structural forms of the rotating support part 13. For example, the other end of the blade driving part 4 is formed with a limiting groove aligned with the output shaft of the driving motor 2, and the rotating support part 13 is a supporting shaft pin extending into the limiting groove along the second direction. The present embodiment does not limit the matching method of the rotating support part 13 and the other end of the blade driving part 4; the rotating support part 13 is located between the first connecting part 11 and the second connecting part 12, so that the force from the other end of the blade driving part 4 borne by the rotating support part 13 can be transmitted to the grille frame 3; there are many ways to connect the first connecting part 11 and the second connecting part 12 with the grille frame 3, for example, it can be a detachable connection or an integral fixed connection, which is not limited in the present embodiment.

[0047] The technical solution provided by the utility model is to set a limit bracket 1 on the grille frame 3, and provide support for the other end of the blade driving part 4 that is isolated relative to the driving motor 2 through the rotating support part 13 on the limit bracket 1, thereby improving the rotational stability of the blade driving part 4, and then improving the opening and closing control accuracy of the driving motor 2 on the blade 5.

[0048] Specifically, see Figure 1 In some embodiments, the rotation support portion 13 includes a connection socket 131 extending along the second direction, and the connection socket 131 is used for plugging the first protrusion 41 provided on the blade driving portion 4.

[0049] It should be noted that, it can be understood from “the connecting socket 131 is used for the first protrusion 41 provided on the blade driving part 4 to be plugged in” that the first protrusion 41 is located at the other end of the blade driving part 4 away from the driving motor 2; the connecting socket 131 at least needs to be passed through toward the blade driving part 4 so that the first protrusion 41 on the blade driving part 4 can be inserted and plugged in, and the other end of the connecting socket 131 can be closed or passed through, and this embodiment does not limit this.

[0050] According to the above technical solution, support is provided for the blade drive unit 4 by setting a connecting socket 131 for the first protrusion 41 on the blade drive unit 4 to be plugged in. This can provide support and limitation for the first protrusion 41 in all directions perpendicular to the second direction, and the supporting and limiting effects of the connecting socket 131 are more comprehensive.

[0051] Furthermore, in some implementations, the limiting bracket 1 is locally thickened along the second direction to form a limiting boss 14 , the limiting boss 14 is used to abut against the blade driving part 4 , and the connecting hole 131 is penetrated through the limiting boss 14 .

[0052] It should be noted that after the limiting bracket 1 is correctly installed on the grille frame 3, the limiting abutting surface of the limiting boss 14 should be arranged towards the output shaft of the driving motor 2. One end of the blade driving part 4 is installed on the output shaft, and the other end abuts against the limiting abutting surface of the limiting boss 14, so as to be limited in the second direction, and the position accuracy of the blade driving part 4 can be improved.

[0053] For the connection between the first connecting part 11 and the grille frame 3, please refer to Figure 1 、 Figure 5 and Figure 6 , in an embodiment, a hook part 11a is formed on the first connecting part 11, and the hook part 11a is used to be arranged on the hook matching part 34 on the grille frame 3.

[0054] It should be noted that the hook part 11a is used to be arranged on the hook matching part 34 on the grille frame 3. The hook matching part 34 can be a cross bar, and the hook part 11a can be buckled on the cross bar through its notch to form a lapping form. Of course, the hook matching part 34 can also be any other convex structure as long as it can limit the movement of the hook part 11a in the third direction. This embodiment does not make a limitation in this regard; in this embodiment, after the intake grille module 100 with the limiting bracket 1 is correctly installed on the vehicle, the first connecting part 11 is usually above the second connecting part 12.

[0055] According to the above technical solution, by forming the hook part 11a on the first connecting part 11, the hook connection and lapping with the hook matching part 34 on the grille frame 3 can be realized, which is convenient for later disassembly, replacement and maintenance of the limiting bracket 1. At the same time, the lapping connection method usually has the advantage of being easy to operate compared with the fixed connection method.

[0056] Furthermore, please refer to Figure 1 , in an embodiment, a second convex part is further formed on the side surface of the hook part 11a in the second direction, and the second convex part is used to be cooperatively connected to the first concave part arranged on the grille frame 3.

[0057] It should be noted that the function of the second convex part is to cooperate with the first concave part on the grille frame 3 to achieve a limiting effect. The second convex part can be any shape of convex, for example, the second convex part can be a hemispherical convex. This embodiment does not make a limitation in this regard.

[0058] According to the above technical solution, a second convex part is formed on the side surface of the hook part 11a in the second direction. After the hook part 11a is lapped on the hook matching part 34, through the limiting cooperation between the second convex part and the first concave part, the movement of the hook part 11a in any direction perpendicular to the second direction can be limited, ensuring the connection stability between the first connecting part 11 and the grille frame 3.

[0059] It should be noted that to achieve a stable limiting effect, the second convex portion can be set to be relatively large, or can be set to be small and numerous. Considering that the grille frame 3 generally belongs to a sheet metal structure and lightweight requirements need to be taken into account, the specifications of the first concave portion may be difficult to meet the limiting requirements. Therefore, multiple second concave portions 111 can be provided. Correspondingly, multiple first concave portions need to be formed on the grille frame 3.

[0060] Please refer to Figure 1 , in one embodiment, a third convex portion 121 is further formed on the side surface of the second connecting portion 12 in the second direction. The third convex portion 121 is used to cooperate and connect to the second concave portion 111 provided on the grille frame 3.

[0061] It should be noted that the function of the third convex portion 121 is to cooperate with the second concave portion 111 on the grille frame 3, thereby achieving a limiting effect. The third convex portion 121 can be a convex portion of any shape. For example, the third convex portion 121 can be a hemispherical convex portion, and this embodiment does not make any limitation thereto.

[0062] According to the above technical solution, a third convex portion 121 is formed on the side surface of the second connecting portion 12 in the second direction. After the second connecting portion 12 is connected to the grille frame 3, through the limiting cooperation between the third convex portion 121 and the second concave portion 111, the movement of the hook portion 11a in any direction perpendicular to the second direction can be restricted, ensuring the connection stability between the second connecting portion 12 and the grille frame 3.

[0063] It should be noted that to achieve a stable limiting effect, the third convex portion 121 can be set to be relatively large, or can be set to be small and numerous. Considering that the grille frame 3 generally belongs to a sheet metal structure and lightweight requirements need to be taken into account, the specifications of the second concave portion 111 may be difficult to meet the limiting requirements. Therefore, multiple third concave portions can be provided. Correspondingly, multiple second concave portions 111 need to be formed on the grille frame 3.

[0064] Regarding the connection between the second connecting portion 12 and the grille frame 3, please refer to Figure 1 , Figure 5 and Figure 6 , in one embodiment, a clamping portion 12a is formed on the second connecting portion 12. The clamping portion 12a is used to be clamped to the clamping and cooperating portion 33 provided on the grille frame 3.

[0065] It should be noted that the "clamping and cooperating portion 33" is used to cooperate with the clamping portion 12a, and it is usually a groove or through hole provided facing the clamping portion 12a. After the clamping portion 12a extends into the groove or through hole, it can be combined and connected with the clamping features therein. This embodiment does not make any limitation thereto.

[0066] According to the above technical solution, by forming the clamping portion 12a on the second connecting portion 12, the detachable connection with the clamping mating portion 33 on the grille frame 3 can be achieved, which facilitates the disassembly, replacement and maintenance of the limiting bracket 1 in the later stage. At the same time, the clamping connection method generally has the advantage of being easy to operate compared with the fixed connection method.

[0067] Further, in an embodiment, a fourth convex portion 122 is further formed on the side surface of the clamping portion 12a in the third direction, and the fourth convex portion 122 is used to be cooperatively connected to a third concave portion provided on the grille frame 3; and / or, the clamping portion 12a includes a double-headed clip.

[0068] It should be noted that after the intake grille module 100 with the limiting bracket 1 is correctly installed on the vehicle, the "third direction" is generally the length direction of the vehicle.

[0069] The above two parallel technical solutions, "a fourth convex portion 122 is further formed on the side surface of the clamping portion 12a in the third direction, and the fourth convex portion 122 is used to be cooperatively connected to a third concave portion provided on the grille frame 3" and "the clamping portion 12a includes a double-headed clip", can be set alternatively or simultaneously. Obviously, the effect of setting them simultaneously is better.

[0070] According to the above technical solution, after the clamping portion 12a is clamped to the clamping mating portion 33 on the grille frame 3, through the fourth convex portion 122 formed on the side surface of the clamping portion 12a in the third direction, it can be cooperatively connected to the third concave portion on the grille frame 3. With this setting, the movement of the clamping portion 12a along the first direction and the second direction can be restricted, thereby improving the assembly stability of the limiting bracket 1 and the grille frame 3; and after the clamping portion 12a is set as a double-headed clip, the clamping stability of the clamping portion 12a and the clamping mating portion 33 can be further improved. At the same time, compared with other types of clamping portions 12a (such as single-headed clips), the double-headed clip also has the effect of being easily clamped to the clamping mating portion 33.

[0071] Specifically, please refer to Figure 6 , the clamping portion 12a extends towards the second direction, so that through the clamping cooperation between the clamping portion 12a and the clamping portion 12a, the freedom degrees of the clamping portion 12a along the first direction and the third direction can also be restricted.

[0072] In an embodiment, the material of the limiting bracket 1 includes nylon and glass fiber; and / or, on the second direction, ribs 15 are formed on the periphery of the limiting bracket 1.

[0073] It should be noted that the material of the limit bracket 1 includes nylon and glass fiber, and the composition ratio of nylon and glass fiber can be any ratio. In one ratio, nylon accounts for 70% and glass fiber accounts for 30%. The material of nylon plus glass fiber enables the limit bracket 1 to have good dimensional stability, toughness, high temperature resistance and corrosion resistance.

[0074] That "a rib 15 is formed on the periphery of the limit bracket 1" means that a groove is formed in the middle of the limit bracket 1 relative to the rib 15. This concave-convex structural feature can significantly increase the strength of the limit bracket 1 and improve the supporting performance for the blade driving part 4.

[0075] For the above three parallel technical solutions, namely, "a third convex part 121 is further formed on the side surface of the second connecting part 12 in the second direction", "the material of the limit bracket 1 includes nylon and glass fiber", and "in the second direction, a rib 15 is formed on the periphery of the limit bracket 1", they can be set selectively, can be set in pairs, or can be set simultaneously. Obviously, the effect of setting them simultaneously is better.

[0076] Please refer to Figures 2 to 4 , the present utility model further provides an intake grille module 100, which includes a grille frame 3, a limit bracket 1, a blade driving part 4 and blades 5. A driving motor 2 is arranged on the grille frame 3 and a grille opening 31 is formed. The first connecting part 11 and the second connecting part 12 of the limit bracket 1 are respectively connected to different positions of the grille frame 3. The rotating support part 13 of the limit bracket 1 is opposite to the output shaft of the driving motor 2 in the second direction. One end of the blade driving part 4 is drivingly connected to the output shaft, and the other end is supported on the rotating support part 13 of the limit bracket 1 and is rotationally matched with the rotating support part 13. The blades 5 are rotatably arranged on the grille frame 3 and are drivingly connected to the blade driving part 4 to open or close the grille opening 31. The specific structure of the limit bracket 1 refers to the above embodiments. Since the intake grille module 100 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, there are many ways to drive the blades 5 to open and close by the rotation of the blade driving part 4, and this embodiment does not limit this.

[0077] Furthermore, in one embodiment, the rotating support part 13 includes a connecting jack 131, the blade driving part 4 is formed with a first convex part 41, and there is a unilateral assembly gap between the first convex part 41 and the connecting jack 131, and the unilateral assembly gap is between 0.09 mm and 0.11 mm.

[0078] It should be noted that the first convex portion 41 is usually a cylindrical convex portion to facilitate rotation in the connection jack 131. Due to the existence of the unilateral assembly gap, the first convex portion 41 of the blade driving portion 4 can be rotatably arranged in the connection jack 131. By setting the value of the unilateral assembly gap between 0.09 mm and 0.11 mm, on the premise of ensuring the smooth rotation of the first convex portion 41, the rotational accuracy of the blade driving portion 4 can also be ensured.

[0079] Specifically, the first convex portion 41 and the connection jack 131 have a unilateral assembly gap of 0.01 mm.

[0080] Furthermore, in an embodiment, the grille frame 3 is formed with a limiting recess 32 opening towards the third direction. The limiting recess 32 has two side walls opposite to each other in the second direction. The first connecting portion 11 of the limiting bracket 1 is arranged in the limiting recess 32 and is in contact with the two side walls.

[0081] After the first connecting portion 11 of the limiting bracket 1 is arranged in the limiting recess 32, the two side walls of the limiting recess 32 opposite to each other in the second direction can form a contact limit on the first connecting portion 11, thereby preventing the second connecting portion 12 from moving in the second direction, and thus improving the installation stability of the limiting bracket 1.

[0082] Specifically, a hook portion 11a is formed on the first connecting portion 11. A hook mating portion 34 is also formed in the limiting recess 32. The hook portion 11a is arranged in the hook mating portion 34 on the grille frame 3. The specific setting method can be that the hook portion 11a is snapped into the hook mating portion 34, or the hook portion 11a is lapped onto the hook mating portion 34. This embodiment does not limit this.

[0083] The above two parallel technical solutions, "the rotation support portion 13 includes a connection jack 131, the blade driving portion 4 is formed with a first convex portion 41, the first convex portion 41 and the connection jack 131 have a unilateral assembly gap, and the unilateral assembly gap is between 0.09 mm and 0.11 mm" and "the grille frame 3 is formed with a limiting recess 32 opening towards the third direction. The limiting recess 32 has two side walls opposite to each other in the second direction. The first connecting portion 11 of the limiting bracket 1 is arranged in the limiting recess 32 and is in contact with the two side walls" can be set alternatively or simultaneously. Obviously, the effect of setting them simultaneously is better.

[0084] There are various ways to drive the blade 5 to open and close by the rotation of the blade driving portion 4. For example, please refer to Figure 4 、 Figure 6 and Figure 7In some embodiments, the blade 5 includes a first blade 51 arranged near the top end of the grille frame 3, and a second blade 52 arranged near the bottom end of the grille frame 3; a first shaft pin 42 and a second shaft pin 43 are formed at the other end of the blade driving unit 4 away from the driving motor 2, and the first shaft pin 42 and the second shaft pin 43 are respectively located on both sides of the limiting bracket 1 along the third direction and extend along the second direction, wherein the length of the first shaft pin 42 is greater than the length of the second shaft pin 43, and the first shaft pin 42 is connected to the shaft pin of the first blade 51 through the first connecting rod 6, and the second shaft pin 43 is connected to the shaft pin of the second blade 52 through the second connecting rod 7.

[0085] It should be noted that the shaft pins and the rotating shafts of the first blade 51 and the second blade 52 are eccentrically arranged, so that the first blade 51 or the second blade 52 can be driven to rotate and open or close through the rotating shaft by pulling or pushing the shaft pin.

[0086] Since the length of the first axle pin 42 is greater than that of the second axle pin 43 , after the first connecting rod 6 and the second connecting rod 7 are assembled on the blade driving unit 4 , there is also misalignment along the second direction, thereby avoiding interference between the first connecting rod 6 and the second connecting rod 7 during transmission activities.

[0087] Since the first axle pin 42 and the second axle pin 43 are located on both sides of the limiting bracket 1 along the third direction, in the process of the blade driving unit 4 rotating to open the blade 5, the first axle pin 42 drives the first connecting rod 6 to push the axle pin of the first blade 51, and the second axle pin 43 drives the second connecting rod 7 to pull the axle pin of the second blade 52, thereby driving the first blade 51 and the second blade 52 to rotate and open. Conversely, in the process of the blade driving unit 4 rotating to close the blade 5, the first axle pin 42 drives the first connecting rod 6 to pull the axle pin of the first blade 51, and the second axle pin 43 drives the second connecting rod 7 to push the axle pin of the second blade 52, thereby driving the first blade 51 and the second blade 52 to rotate and close.

[0088] Based on the diversity of appearance shapes, in the existing technical solutions, the extension direction of the rotation axis of the blade 5 is not the traditional horizontal direction, but usually forms a certain angle with the horizontal direction. This causes the connecting rod transmission mechanism to shake during movement, resulting in abnormal noise and affecting the appearance gap and surface difference between the blade 5 and the opponent, reducing the exquisiteness of the appearance.

[0089] The air intake grille module 100 provided by the utility model has the first axle pin 42 and the second axle pin 43 of the blade driving part 4 in the second direction, so the axial direction of the first blade 51 and the second blade 52 driven to rotate through the first connecting rod 6 and the second connecting rod 7 is also in the second direction, which can effectively control the matching state of the motion mechanism and the appearance blade 5, and at the same time avoid the problems of abnormal noise, appearance gap and surface difference between the motion mechanism and the appearance blade 5 during the driving of the vehicle.
