DETAILED DESCRIPTION

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] The active air intake grille system is arranged before the condenser and the front bumper. Its working principle is to adjust the amount of cooling air entering the engine compartment, reduce the internal circulation resistance, and achieve energy saving and consumption reduction by measuring the engine coolant temperature, oil temperature, air conditioning system status, intake air temperature and other information, and reasonably controlling the opening of the air intake grille blades according to different driving conditions of the car. The existing active air intake grille system structure design generally includes a front guide frame, an active air intake grille body, and a rear guide frame. The front bumper shapes of different models are different, and the interfaces with the front guide frame are different, resulting in the front guide frame cannot be shared, which is costly. At the same time, the shape of the front bumper is not fully compatible with the shape of the air intake grille, so that the air intake grille can only be set on the inside of the front bumper, and the wind resistance reduction effect is poor.

[0037] The present invention provides an air intake grille, referring to Figures 1 to 6 , is an embodiment of the vehicle air intake grille proposed by the present invention, and the vehicle air intake grille will be described in detail below with reference to specific drawings.

[0038] like Figure 1 As shown, a vehicle air intake grille of the present invention includes: a frame 1, a blade 2, a connecting rod assembly 3 and a drive motor 4, a grille opening for air intake is formed on the frame 1, the connecting rod assembly 3 and the drive motor 4 are both fixed to the frame 1 by a first fastener, and the drive motor 2 is transmission-connected to the blade 2 through the connecting rod assembly 3, and is used to drive the blade 2 to rise and fall along the height direction of the vehicle through the connecting rod assembly 3, and the blade will not partially bulge outward after the blade is opened, which meets the requirements of pedestrian protection regulations, and the blade 2 is fixedly connected to the connecting rod assembly 3 by a second fastener, and a plurality of first matching fixing holes and third matching fixing holes fixedly connected to the connecting rod assembly 3 and the drive motor 4 are provided on the frame 1, and a plurality of second matching fixing holes fixedly connected to the connecting rod assembly 3 are provided on the blade 2.

[0039] like Figure 3 and Figure 4As shown, the connecting rod assembly 3 and the driving motor 4 are connected by a spline shaft 5, and the driving motor 4 is provided with a plurality of first fixing holes fixedly connected to the frame 1, and the spline shaft 5 also includes a shaft body, an internal spline, and an external spline. The connecting rod assembly 3 includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33 and a fourth connecting rod 34; a clamping hole 311 is provided at one end of the first connecting rod 31, and a plurality of bending surfaces 321 are provided on the second connecting rod 32.

[0040] Specifically, the third connecting rod 33 includes a hinge rod 330, a connecting surface 333, a protruding surface 334 and a force-bearing surface 335. The hinge rod 330 and the protruding surface 334 are vertically arranged on two surfaces of the same edge of the connecting surface. The force-bearing surface 335 is opposite to the extension direction of the connecting surface 333 and is parallel to each other. The protruding surface 334 and the force-bearing surface 335 are for the purpose of cooperating with the installation of the blade 2, so that the installation of the blade 2 is more stable, the force-bearing area is large and more uniform. A bent arc surface 331A is arranged in the middle of the hinge rod 330. The side where the bent arc surface 331A is connected to the hinge rod 330 and the connecting surface 333 is a connecting end 332. A reinforcing rib 332A is arranged on the connecting end 332, and the other side is a hinge end 331. The connecting rod 330 is relatively long. When the blade 2 is subjected to a large force and the force is transmitted to the connecting end 332, the reinforcing rib 332A strengthens the stability of the connection force point. The connecting surface 333 is provided with a plurality of second fixing holes fixedly connected to the blade 2; the fourth connecting rod 34 is a U-shaped connecting rod as a whole, and the fourth connecting rod 34 includes a fixing plane 341 and two parallel surfaces vertically connected to the fixing plane 341. Among the two parallel surfaces, the one close to the drive motor 4 is the first parallel surface 343, and the one away from the drive motor 4 is the second parallel surface 342. The first parallel surface 343 is provided with a first limiting hole, the second parallel surface 342 is provided with a second limiting hole, and the fixing plane 341 is provided with a third fixing hole fixedly connected to the frame 1.

[0041] The connection mode of the four-link structure in the connecting rod assembly 3 is that one end of the first connecting rod 31 is fixedly connected to the spline shaft 5, the other end of the first connecting rod 31 is hinged to the third connecting rod 33 for relative rotation, the second connecting rod 32 is hinged to the third connecting rod 33 and the fourth connecting rod 34 for relative rotation, one end of the first connecting rod 31 is hinged at the hinge end 331 near the bending arc surface 331A, the other end of the first connecting rod 31 is provided with a rectangular clamping hole 311 for the shaft body of the spline shaft 5 to pass through and connect and fix, one end of the second connecting rod 32 is hinged to the end of the hinge end 331, the other end of the second connecting rod 32 is hinged to the inner side of the U-shaped opening edge of the second parallel surface 342 of the fourth connecting rod 34, the first connecting rod 31 and the second connecting rod 32 are hinged on the same side of the hinge end 331, and one end of the shaft body is cylindrical An internal spline is provided on the surface to cooperate with the external spline on the drive motor 4. The spline has strong bearing capacity, good centering, good guiding, small stress concentration and convenient processing. The other end of the shaft body is rectangular and passes through the first limiting hole, the second limiting hole and the rectangular clamping hole 311 in sequence and is fixedly connected to the first connecting rod 31 through a clamping ring. The drive motor 4 can drive the shaft rod to rotate through the cooperation of the internal spline and the external spline. The cooperation of the rectangular shaft body and the rectangular clamping hole 311 can allow the shaft body and the first connecting rod 31 to maintain relative static rotation. The clamping ring is used to prevent the first connecting rod 31 from falling off the shaft body, and then drives the first connecting rod 31 to rotate clockwise or counterclockwise. The hinge is a riveted hinge, which includes a riveted screw, a riveted nut and a gasket. Inserting a gasket between the riveted components can reduce friction resistance and make the components rotate relative to each other more smoothly.

[0042] Since the outer side surface of the U-shaped profile of the fourth connecting rod 34 is provided with a bending surface 321, a bending arc surface 331A, and the first connecting rod 31, and the inner side surface of the U-shaped profile of the fourth connecting rod 34 is provided with a second connecting rod 32, the rotation activities of the first connecting rod 31 and the second connecting rod 32 will not hinder each other when the connecting rod assembly 3 is extended or retracted.

[0043] like Figure 5 As shown, when the blade 2 changes from a closed state to an open state, the fourth connecting rod 34 is fixed to the frame 1 and remains motionless, and the driving motor 4 drives the first connecting rod 31 to rotate in a counterclockwise direction through the spline shaft 5, and drives the third connecting rod 33 to translate along the top and rear of the vehicle. The third connecting rod 33 also translates and retracts the blade 2 along the top and rear of the vehicle, and the third connecting rod 33 rotates in a counterclockwise direction with the second connecting rod 32. By adopting the above technical solution, the rotation angle of the first connecting rod 31 can be changed at any time to control the air intake volume when the blade 2 is opened upward or closed downward, thereby solving the heat dissipation problem of the entire vehicle. Simple mechanical control is adopted to make the active air intake grille lightweight and reduce the drag coefficient to improve the endurance. At the same time, the blade 2 will not protrude outward, which meets the requirements of pedestrian protection regulations.

[0044] like Figure 6As shown, the frame of the vehicle air intake grille is fixedly connected to the front bumper. The front bumper shape shown in the AA cross-sectional view has a large curvature along the width of the vehicle toward the rear of the vehicle body. The front bumper shape shown in the BB cross-sectional view has a large curvature along the height of the vehicle from the bottom of the vehicle to the top of the vehicle toward the rear of the vehicle body. The traditional style of active air intake grille cannot well match the curved shape of the front bumper. The blades of the active air intake grille of the present invention can be arbitrarily intercepted from the shape of the front bumper, and the size of the blades can be adjusted according to the thermal management requirements to achieve the effect of large-size blades. The blades can also be divided into multiple small blades, and multiple second matching fixing holes are respectively provided on the small blades. The blades and the front bumper can be better matched, and the wind resistance can be more effectively reduced to ensure the heat dissipation requirements of the whole vehicle. At the same time, the sports appearance effect is more significant, which can enhance the technological sense of the whole vehicle.

[0045] like Figure 2 As shown, the first fastener includes a first bolt, a first nut, a third bolt and a third nut. The first bolt passes through the first fixing hole and the first matching fixing hole in sequence to lock the drive motor 4 and the frame 1 through the first nut. The third bolt passes through the third fixing hole and the third matching fixing hole in sequence to lock the fourth connecting rod 34 and the frame 1 through the third nut; the second fastener includes a second bolt and a second nut. The second bolt passes through the second fixing hole and the second matching fixing hole in sequence to lock the small blade and the third connecting rod 33 through the second nut.

[0046] In the embodiment scheme of the present invention, a four-bar linkage is mainly used to realize the translational movement of the active air intake grille blades, avoiding the flipping of the blades when they are opened. Other schemes of adding connecting rods on the basis of the four-bar linkage can also achieve the functions of the present technical scheme and are also included in the scope of the present invention, such as adding a set of self-locking connecting rods.

[0047] In the embodiment of the present invention, the active air intake grille further includes: a control module, which is electrically connected to the drive motor 4. Specifically, the control module controls the drive motor 4. When the heat dissipation system requires a larger air intake, the control module controls the drive motor, and the drive motor 4 drives the first connecting rod 31 to rotate counterclockwise through the spline shaft 5, and then drives the third connecting rod 33, and the third connecting rod 33 drives the blade 2 to lift, thereby increasing the air intake area at the grille opening and allowing more air to enter; when the heat dissipation system requires a smaller air intake, the control module controls the drive motor 4, and the drive motor 4 drives the first connecting rod 31 to rotate clockwise through the spline shaft 5, and then drives the third connecting rod 33, and the third connecting rod 33 drives the blade 2 to descend, thereby reducing the air intake area at the grille opening, limiting the entry of air, and improving aerodynamics.

[0048] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
