Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, and in particular to an active air intake grille with bionic motion. Background Art

[0002] To ensure the normal operation of the automobile engine, an active grille (AGS) is usually installed at the front of the car to allow air to enter the engine compartment, thereby taking away the heat generated by the engine compartment in time. The active grille is a mechanism that reduces wind resistance by reducing or even completely closing the grille opening under certain working conditions. Through the integrated active grille control module, the active grille is closed at high vehicle speeds and low cooling requirements to reduce wind resistance and improve fuel economy or electric vehicle range; the active grille is opened when the cooling demand is high to meet the heat dissipation requirements of the automobile cooling module.

[0003] The existing AGS in the market is basically conventionally opened, horizontally or vertically. The active air intake grille lacks a structural setting that can achieve a welcoming effect, which cannot meet the human-computer interaction of future smart cars. In the future, OEM's vehicle lights and other moving parts will have more and more rhythmic effects. Human-computer interaction and intelligent control can bring users a new driving experience. In addition, the conventionally opened AGS has the following defects: it usually adopts a fixed open or closed state and cannot be dynamically adjusted according to vehicle needs and environmental conditions; the binary control method of opening or closing limits its ability to optimize aerodynamic effects and cooling effects; it lacks intelligence and adaptive capabilities. In addition, there are the following disadvantages: 1. To achieve sequential opening, multiple motors are required, and the manufacturing cost is high; 2. There is no sequential opening movement method, most of which are synchronous opening mechanisms, and bionic movement cannot be achieved; 3. Multiple drive shafts are used to open multiple sets of blades, with a large number of parts and low manufacturing feasibility. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to propose a bionic motion active air intake grille. By controlling the blades and the lever through the driving component, the blades can be opened in various forms (such as timed opening, shaking, and synchronous opening). It can be mass-produced and realize bionic motion (the bionic motion refers to the bionic action of birds (such as swans) spreading their wings), which can improve the aerodynamic effect, optimize the cooling effect, save energy and be environmentally friendly. By driving the driving components on both sides with a single motor, the driving shaft on one side can realize the opening of multiple groups of blades, which can effectively reduce costs and achieve the motion effect at the lowest cost.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The present invention provides an active air intake grille of bionic motion, the active air intake grille of bionic motion (AGS) comprises a fixing frame assembly, a driving assembly, blades and a lever; the driving assembly, the blades and the lever are all fixed on the fixing frame assembly; the driving assembly comprises a driving shaft and a driving rod; the driving rod is connected to the driving shaft; the driving rod is connected to the lever via a connecting block; the blades are fixed on the lever.

These all belong to the protection scope of the present invention.

[0046] Any features such as preparation methods, materials, structures or composition ratios that are not clearly described in this technical solution shall be deemed as common technical features disclosed in the prior art.

[0047] Example 1

[0048] refer to Figures 1 to 16 This embodiment provides a bionic motion active air intake grille, which includes a fixing frame assembly, a driving assembly, a blade 1 and a lever 2; the driving assembly, the blade 1 and the lever 2 are all fixed to the fixing frame assembly; the driving assembly includes a driving shaft 3 and a driving rod 4; the driving rod 4 is connected to the driving shaft 3; the driving rod 4 is connected to the lever 2 through a connecting block 5; the blade 1 is fixed to the lever 2. The internal structure includes the driving assembly, the blade 1 and the lever 2 except the fixing frame assembly.

[0049] The driving assembly further includes a motor; the motor includes a motor body 6 and a motor output shaft 7; the motor output shaft 7 is connected to the driving shaft 3 to drive the driving shaft 3.

[0050] The two sets of driving components are respectively connected to the two sides of the motor output shaft 7 through the ball joint 8 to realize the single motor driving the bilateral active air intake grille. The ball joint 8 includes a male end 8-1 arranged at one end of the driving shaft 3 and a female end 8-2 arranged at one end of the motor; the male end and the female end are movably connected.

[0051] Each set of driving components includes a driving shaft 3 and 9 driving rods 4 , that is, a single-side driving component has 9 rows of rotating blades 1 , and the 9 driving rods 4 are all connected to the driving shaft 3 .

[0052] The fixing frame assembly includes a bracket 9 , a body 10 , a decorative plate 11 and an outer frame 12 ; the outer frame 12 , the body 10 , and the decorative plate 11 are all fastened and fixed on the bracket 9 .

[0053] The upper and lower ends of the blade 1 are axially connected to the body 10 respectively.

[0054] The fixed frame assembly is a symmetrical structure; the two sets of drive assemblies are symmetrically installed on the fixed frame assembly, and Y0 in the figure is the symmetry axis.

[0055] A plurality of U-shaped grooves 2-1 are arranged in parallel on the lever 2; the blades 1 are connected to the U-shaped grooves 2-1 in a one-to-one correspondence, and a single lever 2 is used to drive a plurality of blades 1, which can ensure the synchronization of a single row of blades 1; the blades 1 are axially connected to the U-shaped grooves 2-1.

[0056] Each blade 1 on the single-row lever 2 forms a separate rotating system.

[0057] The blade 1 is a rhombus-shaped blade (rhombus piece).

[0058] like Figure 8 As shown, the motor output shaft 7 rotates around the Y direction, drives the drive shaft 3 to rotate through the ball joint 8, and then drives the lever 2 through the drive rod 4 to drive the blade 1 to rotate in the Z direction. That is, the motor output shaft 7 rotates around the Y direction, and through the ball joint 8→drive shaft 3→drive rod 4→lever 2→blade 1, the rotation direction is converted into the Z direction rotation of the blade 1, wherein, as Fig.12 , 13 As shown, the driving shaft 3, the connecting block 5, the blade 1, and the lever 2 form a four-bar structure, and w, x, y, and z are connection points respectively.

There is always a column that is fully open; D. There is always a column that is in the process from fully open to fully closed; E. There is always a column that is in the process from fully closed to fully open; H. There are always two columns in motion. Among them, the arrangement of the first to ninth columns on a single side is as follows Figure 1 As shown in the figure, after all blades 1 are turned on sequentially, they pause for a few seconds and then turn on synchronously. This pause period is considered as jitter. The synchronous turning on means that all blades 1 rotate at the same time.

[0060] In summary, the mechanical transmission path of a single row of blades 1 (such as Figure 8As shown): the motor 6 rotates, the motor 6 drives the motor output shaft 7 to rotate, the motor output shaft 7 drives the drive shaft 3 to rotate, the drive shaft 3 drives the drive rod 4 to rotate, the drive rod 4 drives the lever 2 to rotate, and the lever 2 drives the blade 1 to rotate; the opening order of the multiple rows of blades 1 is based on the different arrangement positions of the track (a plurality of tracks are provided on the drive shaft 3, each track corresponds to each row of rotating blades 1, one end of the drive rod 4 is slidably connected to the track, the shape of the track is different, the movement of the drive rod 4→lever 2→blade 1 is different, and different movement effects can be produced by setting the shape of the track) and opened according to the different rotation angles of the drive shaft 3.
