Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to an active air intake grille capable of realizing folding movement of blades. Background Art
[0002] The active grille is an air intake grille that can automatically adjust the opening and closing degree. It can automatically adjust the air intake volume and wind resistance according to the needs of the vehicle, thereby improving fuel economy and engine efficiency. For fuel vehicles, the active grille can automatically close the blades to quickly heat up the cabin when the engine temperature is low; when the engine operating temperature is too high, the blades are automatically opened to dissipate heat from the cabin. In addition, after the vehicle reaches a certain speed, closing the active grille blades can also reduce the wind resistance of the entire vehicle, thereby improving the fuel economy of fuel vehicles. For electric vehicles, the need to cool the cabin and reduce the wind resistance of the entire vehicle still exists. In addition, electric vehicles also have additional cooling battery packs and personalized design needs. Therefore, both fuel vehicles and electric vehicles have a high demand for active grilles.
[0003] The active air intake grilles on the market are mainly composed of frames, blades, connecting rods, motors and other parts. Usually, multiple blades are installed on the frame, and the motor drives multiple blades to move synchronously and parallelly. The movement form is relatively simple. The existing air intake grille blades generally need to be installed on the frame, which requires the frame to have greater rigidity. However, the manufacturing cost of a high-rigidity frame is higher, which also virtually increases the overall cost of the vehicle. Utility Model Content
[0004] The utility model provides an active air intake grille capable of realizing blade folding movement, which can realize the opening and closing of the blade folding form, the movement form has a better sense of design, and the blade does not need to be installed on the outer frame, thereby reducing the requirement on the strength of the outer frame.
[0005] The purpose of the utility model is achieved through the following technical solutions:
[0006] An active air intake grille capable of realizing folding movement of blades comprises an outer frame and blades arranged on the front side of the outer frame, wherein the inner side of the blades is connected to a slider shaft via a slider connecting rod, and an actuator connected to the slider shaft for driving the blades to rotate is arranged at the bottom of the outer frame, wherein the actuator drives the blades to realize folding opening and closing movement on the outer frame.
[0007] Preferably, both ends of the slider shaft are arranged on cylindrical slide rails in the outer frame through sliders, and the cylindrical slide rails are arranged on both sides of the outer frame. The axis of the slider shaft is horizontal and perpendicular to the axis of the cylindrical slide rails. When the blades are folded and opened, the slider reciprocates on the cylindrical slide rails.
[0008] Preferably, the actuator assembly includes an actuator and a drive shaft connected to the actuator, and the drive shaft is connected to the blades through a connecting rod.
[0009] Preferably, the drive shaft is arranged at both ends of the actuator, one end of the drive shaft is connected to the output end of the actuator, and the other end is connected to the connecting rod in an L shape.
[0010] Preferably, the slider connecting rod is pivotally connected to the blade and the slider rotating shaft.
[0011] Preferably, the driving shaft and the slider shaft are arranged parallel to each other.
[0012] Preferably, at least one group of blades is provided, which are symmetrically arranged in upper and lower parts with the slider shaft as the center, and the operation of the actuator drives the blades to open and close in a folding shape relative to each other.
[0013] Preferably, limit rods are provided at both ends of the blade, and the other end of the limit rod is pivotally connected to the outer frame.
[0014] The beneficial effects of the utility model are as follows: the active air intake grille of the utility model does not require the blades to be installed on the frame, so the rigidity requirements of the external frame are relatively low, which can reduce the frame manufacturing cost and assembly difficulty. At the same time, the folding opening and closing movement mode also makes the grille more design-oriented. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-Figure 3 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0020] The utility model proposes an active air intake grille capable of realizing folding movement of blades, comprising an outer frame 1 and blades arranged on the front side of the outer frame. An actuator is arranged at the bottom of the outer frame 1. When the actuator is in operation, it will drive the blades to perform folding opening and closing movement on the air intake grille.
[0021] The blades in the example of the utility model are a group, which are arranged up and down on the outer frame 1, including a first blade 21 and a second blade 22. A slider shaft 7 is arranged on the inner side of the outer frame 1, and the first blade 21 and the second blade 22 are respectively connected to the slider shaft 7 through a slider connecting rod 23 on the back. The slider connecting rod 23 is connected to the blades and the slider shaft 7 through a pivot, that is, the connection can be freely rotated with each other.
[0022] The outer frame 1 is provided with cylindrical slide rails 6 on both sides, and the two ends of the slider shaft 7 are provided on the cylindrical slide rails 6 in the outer frame through sliders 71. The axis of the slider shaft 7 is horizontal and perpendicular to the axis of the cylindrical slide rail 6. When the first blade 21 and the second blade 22 are folded and opened, the slider 71 reciprocates on the cylindrical slide rail 6. In order to enhance the smoothness of the reciprocating motion of the slider shaft 7, a slider ball can be provided in the slider 71.
[0023] The actuator assembly includes an actuator 3 and a drive shaft 4 connected to the actuator 3, wherein the drive shaft 4 and the slider shaft 7 are arranged parallel to each other. The drive shaft 4 is connected to the blade through a connecting rod 5. In this embodiment, two drive shafts 4 are provided, which are respectively placed at both ends of the actuator 3, one end of the drive shaft 4 is connected to the output end of the actuator, and the other end is L-shaped, and the L-shaped end 41 is connected to the connecting rod 5.
[0024] The first blade 21 and the second blade 22 are symmetrically arranged with the slider shaft 7 as the center, and the actuator works to drive the first blade 21 and the second blade 22 to open and close in a folding manner. In order to prevent the blades from exceeding the front end of the vehicle during movement, limit rods 24 are arranged at both ends of the blades, and the other end of the limit rod 24 is pivotally connected to the outer frame.
[0025] In order to better understand the folding and opening principle of the utility model, the movement process is described below:
[0026] When the actuator 3 works (forward or reverse), it drives the drive shaft 4 to work, and the drive shaft 4 pushes the connecting rod 5. The other end of the connecting rod 5 is connected to the blade, which will push the blade. Since the blade is connected to the cylindrical slide rail 6 through the pulley connecting rod 23, when the blade is pushed, the first blade and the second blade will be closed or opened in a folded form.
