Description

Technical Field

[0001] This utility model belongs to the field of automotive air intake grille technology, specifically relating to an external active air intake grille. Background Technology

[0002] The air intake grille, also known as the car's front fascia or front end styling, and the radiator grille, primarily functions to ensure ventilation for components such as the radiator, engine, and air conditioning system. It also prevents damage to internal components from external objects during driving and serves to decorate the front of the car and showcase its individuality. Active grilles are those that automatically adjust their opening degree. Currently, external active grilles on the market have limited overall blade span, and their blade structure is typically limited to horizontal and vertical designs, resulting in a simple structure. The blade drive mechanism is located in the center or on one side. While straight-line grille designs are simple, they are becoming less appealing to consumers due to diversified aesthetic preferences. Furthermore, when the blade drive mechanism is located in the center of the grille, a baffle is needed to hide the drive mechanism for aesthetic purposes. This means that even when the blades are fully open, the baffle in the center of the grille remains closed, preventing a truly full grille opening and thus affecting the final air intake area. Therefore, how to achieve both an aesthetically pleasing external grille design and maximize the air intake area is a technical problem that needs to be solved. Utility Model Content

[0003] This utility model provides an external active air intake grille, which changes the monotonous straight-line blade shape currently on the market, making the grille more aesthetically pleasing and ensuring that the maximum air intake volume is not affected.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An external active air intake grille includes a grille frame, a blade assembly placed within the grille frame, a drive shaft connected to the blade assembly, and a drive mechanism for driving the drive shaft to rotate. The drive mechanism is located on both sides of the drive shaft. The drive shaft includes a first drive shaft and a second drive shaft, which are connected by a universal coupling. When the drive mechanism operates, it drives the drive shaft to rotate, thereby driving the blades to open and close within the grille frame.

[0006] Preferably, the blade assembly is fitted inside the grid frame, and its back side is connected to the drive shaft via a connecting rod.

[0007] Preferably, the driving mechanism is a motor, which is connected to the first drive shaft and the second drive shaft respectively.

[0008] Preferably, the blade assembly includes a first blade assembly and a second blade assembly, wherein one end of the second blade assembly overlaps with one end of the first blade assembly.

[0009] Preferably, the first blade assembly and the second blade assembly are symmetrically arranged with the overlapping end as the center.

[0010] Preferably, the surface of the blade assembly is uniformly distributed in a rhomboid gemstone pattern.

[0011] Preferably, the grille frame includes an outer grille frame and an inner grille frame snapped into the outer grille frame.

[0012] The beneficial effects of this invention are as follows: The blades of this invention are rhomboid gemstone-shaped, which is more aesthetically pleasing and provides more options for grille design. Furthermore, it solves the problem of loose closure of grille blades over long spans, and by hiding the motor on both sides of the back of the grille, it achieves maximum air intake when the blades are fully open, increasing engine air intake and thus improving driving range.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-5 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] This utility model proposes an external active air intake grille, including a grille frame 1, a blade assembly 2 placed within the grille frame 1, a drive shaft 3 connected to the blade assembly 2, and a drive mechanism 4 for driving the drive shaft 3 to rotate. The grille frame 1 consists of an outer grille frame 11 and an inner grille frame 12 snapped and fixed within the outer grille frame 11. In this embodiment, the grille frame 1 has an arc-shaped cross-section. The blade assembly 2 consists of multiple rhomboid gem-shaped blades, where rhomboid gem-shaped means that the shape is rhomboid with an upwardly convex center. Of course, the shape of the blades can also take other forms. The blades are selectively provided with mounting holes 7 for mounting radar probes.

[0021] The blade assembly 2 is snapped into the inner frame 12 of the grille and consists of a first blade assembly 21 and a second blade assembly 22. The second blade assembly 22 overlaps with one end of the first blade assembly 21, and they are symmetrically arranged around the overlapping end. A connecting ring 23 is provided on the back side of the blade assembly, and the connecting ring 23 is connected to a connecting rod 6. The other end of the connecting rod 6 is connected to a drive shaft 3. When the drive shaft rotates, it will drive the connecting rod to pull the blades to rotate. The driving rotation and opening / closing of the blades is a conventional method and will not be described in detail here.

[0022] The drive shaft 3 includes a first drive shaft 31 and a second drive shaft 32. The first drive shaft 31 is connected to the first blade assembly 12 via multiple connecting rods 6. Similarly, the second drive shaft 32 is also connected to the second blade assembly 22 via multiple connecting rods. The first drive shaft 31 and the second drive shaft 32 are connected by a universal coupling 33. The other ends of the first drive shaft 31 and the second drive shaft 32 are respectively connected to a drive mechanism 4, which is a motor. The motors on both sides are fixed to the back of the grille frame with screws, and the grille frame 1 conceals the motors. That is, when the blades are fully open, the grille achieves maximum air intake. In this embodiment, a cover plate 5 is provided behind the drive shaft. The cover plate 5 is connected to the inner frame of the grille, and the drive shaft is located between the inner frame of the grille and the cover plate 5.

[0023] When the two motors are working, they will drive the first drive shaft and the second drive shaft to rotate respectively. Since a universal coupling 33 is provided between the two drive shafts, the rotation between the two drive shafts can be synchronized, thereby achieving synchronization between the two blade assemblies when opening and closing. At the same time, since two drive shafts are used to drive the blades respectively, the problem of incomplete closure between long-span blades caused by using a single drive in the prior art is also solved. The solution to the problem of incomplete closure between long-span blades also provides the possibility of realizing more blade forms for the grille.

[0024] The electrical control connection principle between the external active air intake grille and the vehicle is not the focus of this utility model, so it will not be described in detail here.
