Background

The wind resistance coefficient of the whole vehicle has strong negative correlation with the endurance mileage, namely, the smaller the wind resistance coefficient is, the higher the endurance mileage is. An effective way to reduce the wind resistance coefficient is to add an active air intake grille, which has the function of automatically closing blades on the active air intake grille when the cooling system of the whole vehicle does not need air to dissipate heat, so that the whole vehicle runs in a state of small wind resistance.

When the cooling system of the whole vehicle judges that air is needed for heat dissipation, the air passes through the opened active air inlet grille blades under the flow guiding effect of the wind shield (generally integrated on the active air inlet grille), and finally provides high-speed flowing air for heat dissipation of a cooling module in the cooling system, so that heat exchange is realized.

The windshield on the active air inlet grille is connected with the front grille, and when the vehicle is in accidental collision, if the windshield is not easy to break and collapse, the pedestrian can be greatly injured, namely, the safety performance of the whole vehicle can be greatly reduced.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 5, the active grille shutter structure is schematically shown in fig. 1 to 5, and includes: the wind shield comprises a first wind shield 11, a second wind shield 12 and a connecting piece 3, wherein the first wind shield 11 and the second wind shield 12 are connected through the connecting piece 3.

Specifically, the connecting member 3 is disposed between the first windshield 11 and the second windshield 12, one end of the connecting member 3 is connected to the first windshield 11, and the other end of the connecting member 3 is connected to the second windshield 12.

In some embodiments, the first windshield 11 has a first end 111 and a second end 112 disposed oppositely; the second windshield 12 has a third end 121 and a fourth end 122 which are oppositely arranged; the connecting member 3 is respectively connected to the second end 112 of the first windshield 11 and the third end 121 of the second windshield 12. That is, the connecting member 3 connects one end of the first windshield 11 with one end of the second windshield 12.

By connecting one end of the first windshield 11 with one end of the second windshield 12, a smoother surface can be formed between the first windshield 11 and the second windshield 12, and the wind resistance is reduced.

Optionally, the second end 112 overlaps the third end 121.

Of course, in other embodiments, the connecting member 3 may also be disposed between the first end 111 and the second end 112, for example, the connecting member 3 is connected to the middle between the first end 111 and the second end 112 of the first windshield 11. Similarly, the connecting element 3 may also be disposed between the third end 121 and the fourth end 122, for example, the connecting element 3 is connected to a middle portion between the third end 121 and the fourth end 122 of the second windshield 12.

The first end 111 of the first windshield 11 is used for connecting with a front grille of the vehicle body, and the fourth end 122 of the second windshield 12 is used for connecting with a main frame 300 in a front cabin of the vehicle body. Therefore, the first windshield 11 is located at the front side of the second windshield 12, the first end 111 is the front end of the first windshield 11, the second end 112 is the rear end of the first windshield 11, the third end 121 is the front end of the second windshield 12, and the fourth end 122 is the rear end of the second windshield 12. The front end of the first windshield 11 is connected to the front grille, the rear end of the first windshield 11 is connected to the front end of the second windshield 12, and the rear end of the second windshield 12 is connected to the mainframe 300.

The main frame 300 may serve as a structural reinforcement for the second windshield 12 and other structures. A vent is formed in the main frame 300. The air passes through the first wind shield 11 and the second wind shield 12 in sequence and then passes through the air vent. Specifically, the second wind blocking cover 12 may be cylindrical and cover the air vent. The second windshield 12 and the main frame 300 can be detachably connected to facilitate the disassembly and assembly of the second windshield 12 and the main frame 300, so that when a fracture occurs between the first windshield 11 and the second windshield 12, the whole windshield structure 1 can be disassembled from the main frame 300, and a new windshield structure 1 can be replaced. The second wind shield 12 and the main frame 300 may be detachably fixed by a screw connection or a snap connection.

Similarly, the first windshield 11 and the front grille are also fixed by detachable connection, which includes but is not limited to screw locking, snap fastening, plug insertion, etc.

However, since the main frame 300 of the active grille shutter has a large number of mounting points, the entire structure is strong and is not easily damaged, and thus when the front end of the vehicle collides with a pedestrian or other objects, the windshield connected to the main frame 300 is also difficult to break, which is likely to cause great injury to the pedestrian.

In view of this, in the embodiment of the present application, the thickness of the connecting member 3 is set to be smaller, and the thickness of the connecting member 3 is smaller than the thickness of the first windshield 11 and the thickness of the second windshield 12, respectively. The connecting piece 3 serves as a connecting structure between the first windshield 11 and the second windshield 12, the thickness of the connecting piece 3 is reduced, and as a weakening structure, when a vehicle is collided at the front end, the connecting piece is easy to break at the weakening structure, namely, the first windshield 11 and the second windshield 12 are easy to break, the front end structure of a weakening area, namely, the first windshield 11 is wholly or partially displaced backwards, the energy absorption effect is achieved, and the injury to pedestrians is reduced.

The connecting piece 3 is arranged, so that when the front end of the vehicle collides, the active air inlet grille windshield structure 1 is easy to break and collapse, the buffering and energy absorption effects are achieved, the injury to pedestrians is reduced, and the score of the safety performance test of the whole vehicle is improved.

In some embodiments, the connecting member 3 is vertically disposed between the second end 112 and the third end 121. I.e. the connection member 3 is substantially perpendicular to the first windshield 11 and the second windshield 12. With the vertical arrangement, when the first windshield 11 is impacted by an external force, the external force is perpendicular to the connecting member 3, so that the connecting member 3 is more easily broken.

In other embodiments, the connecting member 3 may be inclined with respect to the first windshield 11 and the second windshield 12.

Referring to fig. 3, in order to form a better weakening structure, so that the first windshield 11 is more easily broken and collapsed, optionally, the thickness T3 of the connecting member 3 is less than one half of the thickness T1 of the first windshield 11, and the thickness T3 of the connecting member 3 is less than one half of the thickness T2 of the second windshield 12. Illustratively, the thickness T1 of the first windshield 11 is 2.0mm to 2.5mm, the thickness T2 of the second windshield 12 is 2.0mm to 2.5mm, and the thickness T3 of the connecting member 3 is 0.8mm.

Optionally, the thickness T1 of the first windshield 11 is equal to the thickness T2 of the second windshield 12. Of course, in other embodiments, the thickness T1 of the first windshield 11 and the thickness T2 of the second windshield 12 may also be different, for example, the thicknesses thereof are approximately equal.

Optionally, the height H of the connector 3 is 1-1.2 times the thickness T3 of the connector 3. In this embodiment, the height H of the connecting member 3 refers to a height of the connecting member 3 extending from the first windshield 11 to the second windshield 12, that is, a height of the connecting member 3 in the up-down direction. The thickness T3 of the connecting member 3 refers to the thickness of the connecting member 3 in the front-rear direction. The height H of the connecting member 3 may be 1, 1.1 or 1.2 times the thickness T3 of the connecting member 3, etc. The height H of the connecting piece 3 is 1-1.2 times of the thickness T3 of the connecting piece 3, so that the first windshield 11 and the second windshield 12 can be prevented from being greatly dislocated in the vertical direction, and an obvious step is prevented from being formed to increase wind resistance, thereby preventing wind trapping at the joint of the first windshield 11, the connecting piece 3 and the second windshield 12.

In some embodiments, the first windshield 11 has a trumpet-shaped structure. Optionally, the first end 111 is flared and the second end 112 is necked down. The first end 111 and the second end 112 are distributed along the penetrating direction of the first windshield 11, that is, the first end 111 and the second end 112 are distributed along the front-rear direction.

The first windshield 11 may be arranged in a tapered manner from front to back, and thus, the inner diameter of the first windshield 11 is gradually reduced from front to back. Of course, the first windshield 11 may also be substantially flared, and the inner diameter may not be completely tapered, for example, in some regions the inner diameter may be the same, and in some regions the inner diameter of the front end may be slightly smaller than the inner diameter of the rear end. Illustratively, the first windshield 11 is bent in the front-rear direction, and the bending angle between two adjacent sections is small, so as to avoid generating a large step to influence the air flow.

In some embodiments, the second windshield 12 is a cylindrical structure. The third end 121 and the fourth end 122 are distributed along the penetrating direction of the second windshield 12, that is, the third end 121 and the fourth end 122 are distributed along the front-rear direction.

The shape of the second windshield 12 substantially matches the shape of the second end 112 of the first windshield 11, so that the second end 112 of the first windshield 11 can be better matched with the third end 121 of the second windshield 12. The cross-sectional shape of the first windshield 11 may be circular, square, or triangular, and correspondingly, the second windshield 12 may be a circular cylindrical structure, a square cylindrical structure, or a triangular cylindrical structure, and so on.

Illustratively, the longitudinal cross section of the first windshield 11 is substantially rectangular, and the longitudinal direction thereof is along the left-right direction and the width direction thereof is along the up-down direction. Correspondingly, the longitudinal section of the second windshield 12 is also rectangular, and the length direction of the second windshield 12 is along the left-right direction, and the width direction is along the up-down direction.

In the embodiment of the present application, the inner diameters of the second wind scooper 12 may be the same, that is, the inner wall of the second wind scooper is a straight wall. Of course, the inner diameter of the second wind shield 12 in some regions may also have a smaller difference, that is, the inner wall of the second wind shield 12 is bent less, and the bending angle between two adjacent sections is smaller.

In some embodiments, the second end 112 and the third end 121 are sleeved with each other, and the connecting member 3 is annular. The connecting member 3 is annularly disposed around the second end 112, so as to connect the second end 112 and the third end 121, so that the integral windshield structure 1 forms a larger annular structure.

In the above, the inner and outer sleeves of the second end 112 and the third end 121 include the following two situations:

in the first case, the second end 112 is sleeved outside the third end 121, and the inner diameter of the second end 112 is larger than the outer diameter of the third end 121.

In the second situation, the second end 112 is sleeved inside the third end 121, and the outer diameter of the second end 112 is smaller than the inner diameter of the third end 121.

Of course, in other embodiments, the second end 112 and the third end 121 may be staggered in the front-back direction, and the two ends do not overlap, so that the height direction of the connecting member 3 is along the front-back direction to connect the second end 112 and the third end 121.

The first windshield 11 in the embodiment of the present application may be an integral structure, or may be formed by connecting a plurality of components in sequence. In some embodiments, the first windshield 11 may be a plurality of first windshields 11, and adjacent first windshields 11 are sleeved and connected with each other. Specifically, the plurality of first windshields 11 are sequentially arranged in the front-rear direction, and two adjacent first windshields 11 are sleeved inside and outside. Similarly, the second windshield 12 may be formed by a single structure or a combination of a plurality of structures.

In addition, two adjacent first windshields 11 may also be connected by the connecting member 3, and two adjacent second windshields 12 may also be connected by the connecting member 3.

Specifically, in some embodiments, the number of the first windshields 11 may be multiple, the multiple first windshields 11 are sequentially distributed along the front-back direction, and two adjacent first windshields 11 are connected by another connecting member 3; and/or the presence of a gas in the atmosphere,

the number of the second wind shields 12 can be multiple, the multiple second wind shields 12 are sequentially distributed in the front-back direction, and two adjacent second wind shields 12 are connected through another connecting piece 3.

By designing a multi-layer easy-collapse structure on the same windshield structure, the maximum distance collapse can be achieved in a smaller arrangement space in the front-back direction.

Optionally, the first windshield 11, the second windshield 12 and the connecting member 3 are integrally manufactured. For example, in some embodiments, the first windshield 11, the second windshield 12 and the connecting member 3 are made of plastic, for example, the first windshield 11, the second windshield 12 and the connecting member 3 are made of hard plastic, and are formed by integral injection molding. The mode of integral manufacturing and forming saves the installation step and is beneficial to the quick assembly of the whole structure.
