[0002] When a car engine is working, it needs a lot of air and releases a lot of heat. If the heat is not dissipated in time, it will cause the engine to overheat, which will affect its normal operation and life. The air intake grille is an air intake device installed in front of the car radiator. It is mainly used for engine heat dissipation and provides the engine with air required for fuel combustion. At present, passive air intake grilles are usually used. Passive air intake grilles are fixed. The size and direction of the air flow channel they can provide are fixed, which makes it impossible to adjust the air intake volume adaptively according to the driving scene.
[0003] As the public's demand for automobile performance continues to increase, compared to passive air intake grilles, the blades of active air intake grilles can adjust the tilt angle in time according to the engine water temperature, thereby adjusting the air intake angle.

[0033] When the car engine is working, it needs a lot of air and releases a lot of heat. If the heat is not dissipated in time, it will cause the engine to overheat, which will affect its normal operation and life. At present, passive air intake grilles are usually used to dissipate heat for the engine. However, passive air intake grilles are fixed, and the size and direction of the air flow channel they can provide are fixed, which makes it impossible to adjust the intake volume adaptively according to the driving scene.
[0034] In order to solve the related technical problems, the present application provides a vehicle, which includes an air intake grille, which is used for engine heat dissipation and provides the engine with air required for fuel combustion. The air intake angle can be adjusted by controlling the blades, which has the characteristics of reducing the wind resistance coefficient of the vehicle, shortening the engine heating time, reducing fuel consumption, and improving the power performance of the vehicle.
[0035] However, currently, the blades of the active air intake grille are exposed when air is taken in, and the exposed blades will affect the shape of the whole vehicle and the air intake efficiency. More importantly, the exposed area of the blades is too large, which can easily cause scratches on the blades during vehicle driving. In order to solve the technical problems existing in the related technology, the present application also provides an air intake grille.
[0036] See also Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of an embodiment of the air intake grille provided by the present application, Figure 2 yes Figure 1 First view of the grille shown.
[0037] The air intake grille 10 includes an outer frame 100, which includes a frame body 110 and a decorative strip 120. The frame body 110 is connected to the front of the vehicle body. The frame body 110 has an air intake window 111. The air intake window 111 penetrates the opposite two side surfaces of the frame body 110 along the air intake direction X of the frame body 110. The air intake window 111 has a side wall. The side wall extends along the air intake direction X to penetrate the opposite two side surfaces of the frame body 110. The area surrounded by the side wall of the air intake window 111 can be used for air to pass through, so as to provide the required air for the vehicle to dissipate heat from the engine. The air intake window 111 can be arranged in the middle of the frame body 110. The decorative strip 120 spans the air intake window 111 in the first direction Y to connect to both sides of the frame body 110. The decorative strip 120 can be arranged on a side of the side wall of the air intake window 111 away from the vehicle body in the air intake direction X. Among them, the first direction Y is perpendicular to the air intake direction X, and the decorative strip 120 connects the two sides of the frame 110 in the first direction Y, and can be prominent on the surface of the frame 110, which can make the decorative strip 120 more solid in structure and more ornamental. In this embodiment, the number of the air intake windows 111 can be one or more, and the number and size of the air intake windows 111 can be adjusted according to actual conditions. For example, the number of the air intake windows 111 can be 1, 2 or 4, and the position of the air intake windows 111 can be limited to the frame 110. The decorative strip 120 can be connected to any two sides of the frame 110, and the decorative strip 120 can be connected to the adjacent two sides of the frame 110, or can be connected to the opposite two sides of the frame 110. The setting of the air intake window 111 and the decorative strip 120 can be set according to actual conditions, and this application is not limited here. In addition, in this embodiment, a plurality of mounting buckles can be set along the circumference of the frame 110, and the outer frame 100 is fixedly connected to the front of the vehicle body through a plurality of mounting buckles set circumferentially. In order to make the outer frame 100 and the vehicle body connected more firmly, screw holes may be further provided on the frame body 110, and the outer frame 100 may be fixedly connected to the vehicle body through the screw holes.
[0038] The blade 200 is arranged in sequence with the decorative strip 120 in the air intake direction X, and the blade 200 is rotatably connected to the two side walls of the air intake window 111, so that the blade 200 can switch between a shielding state and an air intake state. In the shielding state, the blade 200 shields at least a portion of the air intake window 111 along the air intake direction X, and in the air intake state, the decorative strip 120 shields the blade 200 in the air intake direction X. For a clearer description, as shown in FIG. Figure 2As shown, the air intake window 111 on the left side of the air intake grille 10 in the first direction Y is in the shielding state of the blade 200. In the shielding state, the blade 200 is closed to shield the air intake window 111 to reduce the air intake amount; the right side is in the air intake state, and the blade 200 is open in the air intake state to allow air to pass through the air intake window 111. In this way, the blade 200 can be hidden behind the decorative strip 120. The decorative strip 120 spans across the two sides of the air intake window 111, dividing the air intake window 111 into two parts. The decorative strip 120 can divide the air intake window 111 into two adjacent parts, for example, dividing the air intake window 111 into two upper and lower parts, two left and right parts, or two diagonal parts. Different separation methods have different visual effects. In this embodiment, the decorative strip 120 can divide the air intake window 111 into two upper and lower parts in the first direction Y. The air intake amount of the air intake grille 10 can be adjusted by controlling the degree of shielding of the air intake window 111 by the blade 200. When the blades 200 are in the air intake state, the blades 200 are located at the same horizontal plane as the decorative strips 120 in the air intake direction X, so that the decorative strips 120 can effectively protect the blades 200. The number of blades 200 can be one or more, and the number of blades 200 and decorative strips 120 can be equal, more, or less than the number of decorative strips 120. For example, when the number of decorative strips 120 is less than that of blades 200, two blades 200 can be blocked by one decorative strip 120 at the same time in the air intake state; when the number of decorative strips 120 is more than that of blades 200, blades 200 can be blocked by a corresponding decorative strip 120. The specific setting can be made according to the actual situation, and this application does not limit it here.
[0039] The outer frame 100 of the air intake grille 10 provided in the present application is an integrated design, and the outer frame 100 can be installed on the front of the vehicle body alone, or the blades 200 and other corresponding accessories can be installed on the outer frame 100 and then installed on the vehicle body. The outer frame 100 can be installed alone or the blades 200 and other corresponding accessories can be added according to different configurations of the vehicle.
[0040] Through the above-mentioned implementation, the blade 200 is arranged in sequence with the decorative strip 120 in the air intake direction X, so that the blade 200 can be located between the vehicle body and the decorative strip 120, and the blade 200 can be switched between the shielding state and the air intake state to achieve the effect of active air intake, and in the air intake state, the decorative strip 120 shields the blade 200 in the air intake direction X, thereby achieving the purpose of protecting the blade 200 and reducing the influence of the blade 200 on the air intake efficiency.
[0041] See also Figure 3 , Figure 3 for Figure 1 A schematic structural diagram of an embodiment of a blade is shown.
[0042] In some embodiments, the blade 200 has a rotation axis 210 parallel to the first direction Y, and the blade 200 can rotate around the rotation axis 210 to switch the blade 200 between the shielding state and the air intake state. Figure 3 As shown, for better understanding, the rotation axis 210 is a virtual line. The rotation axis 210 of the blade 200 is in the same horizontal plane as the decorative strip 120, and the horizontal plane is parallel to the air intake direction X, thereby ensuring that the blade can be better shielded by the decorative strip in the air intake state. The blade 200 can rotate around the rotation axis 210 to switch the blade 200 between the shielding state and the air intake state, thereby the blade 200 can shield the air intake window 111 to varying degrees, and in the air intake state, the blade 200 can be hidden behind the decorative strip 120 by rotating around the rotation axis 210. In this embodiment, the rotation axis 210 can be located in the middle of the blade 200, so that the space required for the blade 200 to rotate around the rotation axis 210 is minimized, and the outer frame 100 can be more closely combined with the vehicle body.
[0043] See also Figure 4 and Figure 5 , Figure 4 yes Figure 2 The cross-sectional view of the air intake grille along the AA direction is shown. Figure 5 yes Figure 2 The cross-sectional view of the air intake grille along the BB direction is shown.
[0044] In some embodiments, the blade 200 is provided with a first limiting strip 220, and the frame 110 is provided with a second limiting strip 112, and the first limiting strip 220 and the second limiting strip 112 cooperate with each other to limit the blade 200 during the blade 200 rotates around the rotation axis 210. Figure 4 As shown, in the intake state, the blade 200 and the decorative strip 120 are on the same horizontal line, so that the decorative strip 120 covers the blade 200. The first limiting strip 220 is extended to the side of the blade 200 away from the decorative strip 120, and a protrusion may be provided on the side of the blade 200 close to the decorative strip 120. The second limiting strip 112 is provided on a side wall of the intake window 111 in the second direction Z. The blade 200 rotates clockwise from the intake state to the shielding state. Figure 5As shown, the blade 200 is in a shielding state, the raised side of the blade 200 contacts the second limiting strip 112, and the first limiting strip 220 on the other side of the blade 200 contacts the side of the air inlet window 111 away from the second limiting strip 112. The blade 200 cooperates with the first limiting strip 220 and the second limiting strip 112 of the air inlet window 111 to limit the blade 200, thereby preventing the blade 200 from rotating too much, so that the blade 200 can effectively block the air inlet window 111 and reduce the air intake of the air inlet window 111. The first limiting strip 220 is not limited to being set on one side of the blade 200, but can also be set on both sides. The second limiting strip 112 is not limited to being set on one side of the frame 110 in the second direction Z, but can be set on both sides of the frame 110. The specific setting can be based on actual conditions, and this application does not limit it here.
[0045] See also Figure 6 and Figure 7 , Figure 6 yes Figure 1 A second perspective view of the air intake grille shown. Figure 7 yes Figure 6 The structure diagram of one embodiment of the blades, transmission parts and drive motor is shown.
[0046] In some embodiments, there are multiple blades 200, and the multiple blades 200 are spaced apart in the second direction Z, and each blade 200 rotates around its own rotation axis 210 so that each blade 200 switches between a shielding state and an intake state. When the multiple blades 200 are in the shielding state, two adjacent blades 200 may contact each other so that there is no gap between the blades 200. The protrusion of a blade 200 contacts the second limiting strip 112 of the frame 110, and the first limiting strip 220 of the blade 200 away from the side of the protrusion contacts the protrusion of the next blade 200. In this way, the blades 200 contact each other, and the gap between the blades 200 is minimized. The first limiting strip 220 of the last blade 200 contacts the side of the frame 110 away from the second limiting strip 112. Thus, multiple blades 200 contact each other to block the air intake window 111, and multiple blades 200 can prevent the blades 200 from over-rotating by the mutual cooperation of the first limit strip 220 between the blades 200 and the second limit strip 112 of the frame 110. Such a configuration of multiple blades 200 can also reduce the force required for the rotation of each blade 200, and can further reduce the space required for the rotation of the blades 200. In some embodiments, the blades 200 may be provided with a rotating shaft at both ends of the first direction Y, and the rotating shafts at both ends of the blades 200 may be arranged along the rotating axis 210, and the two rotating shafts are respectively connected to the two side walls of the air intake window 111. The blades 200 rotate around the rotating axis 210 to realize the conversion between the shielding state and the air intake state. Among them, the number of blades 200 can be set according to actual conditions, for example, it can be 2, 3, 4 or more.
[0047] In this embodiment, the number of blades 200 can be 3, because the more blades 200 there are, the more decorative strips 120 there are to cover the blades 200. The decorative strips 120 are arranged on the frame 110 and connect the two sides of the air intake window 111. That is to say, the decorative strips 120 also cover a part of the air intake window 111. Therefore, too many blades 200 will indirectly reduce the maximum air intake volume of the air intake grille 10. The number of blades 200 is set to 3, which can not only ensure that the air intake grille 10 has a large air intake volume, but also reduce the distance between the air intake grille 10 and the vehicle body, making the vehicle more compact.
[0048] In some embodiments, the air intake grille 10 further includes a transmission member 300, the transmission member 300 connects a plurality of blades 200, the plurality of blades 200 include active blades 230 and driven blades 240, the active blades 230 are connected to a device for driving the blades 200 to rotate, so that the active blades 230 rotate around their own rotation axis 210, and the active blades 230 can drive the driven blades 240 to rotate around their own rotation axis 210 through the transmission member 300. The blades 200 may be provided with a through hole that cooperates with the transmission member 300, the through hole and the rotation axis are at the same end of the blade 200, and the through hole and the rotation axis are spaced apart at one end of the blade 200. The transmission member 300 is spaced apart with elastic members, and the elastic members can pass through the through holes on the blades 200 to fix the transmission member 300 with the blades 200, and one elastic member is fixedly connected to the through hole of one blade 200. Thus, the active blade 230 is connected with the driven blade 240 through the transmission member 300. When the active blade 230 rotates around the rotation axis 210 through the rotating shaft, a force arm is formed between the elastic member and the rotating shaft, and then the active blade 230 drives the transmission member 300 to rotate due to the design of the elastic member and the rotating shaft. The transmission member 300 drives the driven blades 240 corresponding to the respective elastic members to rotate through the remaining elastic members, and finally the active blade 230 drives the driven blade 240 to rotate around its own rotation axis 210 through the transmission member 300. The blade 200 close to one side of the frame 110 can be set as the active blade 230, and the remaining blades 200 are driven blades 240. Of course, the active blade 230 can also be set between the driven blades 240, which can be set according to actual conditions. In this embodiment, circular holes rotatably connected to the rotating shaft are provided on both side walls of the air inlet window 111 in the first direction Y, circular holes equal to the number of blades 200 are provided at intervals on the side wall close to the transmission member 300, and semicircular holes are provided on the side wall opposite to the side wall to facilitate the installation of the blades 200, and the blades 200 can be installed on the side wall without applying external force to the side wall. In addition, the blades 200 can be installed on the side wall first to pre-fix the blades 200, and then the transmission member 300 is fixedly connected to the plurality of blades 200, which makes it easier to install the transmission member 300.
[0049] In some embodiments, a mounting member may be provided on a side of the air inlet window 111 away from the transmission member 300, and the mounting member is fixedly connected to the frame 110. A plurality of spaced circular holes are provided on a side of the mounting member opposite to the transmission member 300 in the first direction Y, and a rotating shaft rotatably connected to the semicircular hole on the side wall of the air inlet window 111 is rotatably connected to the circular hole on the mounting member to fix the rotating shaft on the side wall. The mounting member may be divided into a mounting seat and a mounting cover, and the mounting cover is provided on the mounting seat. The mounting seat is fixedly connected to the frame 110, and the mounting seat may be provided with a positioning pin and a screw hole, and the mounting cover is provided with a positioning hole and a screw hole corresponding to the positioning pin on the mounting seat, and the mounting cover can be fixedly connected to the mounting seat by screws. The mounting seat and the mounting cover are provided with corresponding semicircular holes, and the circular hole of the mounting member is formed by the semicircular holes on the mounting cover and the mounting seat. The rotating shaft of the blade 200 can be first connected to the corresponding semicircular hole on the mounting seat, and then the mounting cover is fixedly connected to the mounting seat, so that the rotating shaft can be fixed through the circular hole formed by the semicircular holes of the mounting seat and the mounting cover, which can facilitate the installation of the blade 200.
[0050] In some embodiments, there are multiple decorative strips 120, and multiple decorative strips 120 are spaced apart in the second direction Z. In the air intake state, one decorative strip 120 blocks one blade 200 in the air intake direction X. Multiple decorative strips 120 are parallel to each other in the first direction Y, and cross the air intake window 111 in the first direction Y to connect the two sides of the frame 110. The decorative strips 120 are on the same horizontal line as the rotation axis 210 in the air intake direction X, so that the decorative strips 120 can block the blades 200 in the air intake state, thereby protecting the blades 200. The number of decorative strips 120 may be the same as or different from the number of blades 200. For example, the number of decorative strips 120 may be more than the number of blades 200, and only some decorative strips 120 are needed to block the blades 200. The number of decorative strips 120 is the same as the number of blades 200, that is, all decorative strips 120 correspond to one protected blade 200. It can be set specifically according to actual conditions, and this application is not limited here.
[0051] In some embodiments, the outer frame 100 further includes a reinforcing rib 113, which is extended along the second direction Z. The reinforcing rib 113 crosses the air intake window 111 in the second direction Z to connect each decorative strip 120 and both sides of the frame body 110. The reinforcing rib 113 is integrally arranged with the decorative strip 120, and the reinforcing rib 113 extends from one side of the air intake window 111 to the other side in the second direction Z, and crosses and connects with each decorative strip 120, so that the reinforcing rib 113 has a supporting effect on the decorative strip 120, which can improve the bending deformation of the decorative strip 120 in the second direction Z. The reinforcing rib 113 and the decorative strip 120 on the side close to the vehicle body in the air intake direction X can be located in the same horizontal plane, and the reinforcing rib 113 and the decorative strip 120 have a certain gap with the blade 200, so that the reinforcing rib 113 or the decorative strip 120 will not hinder the rotation of the blade 200. In addition to supporting the decorative strip 120, the reinforcing rib 113 also has a certain decorative effect.
[0052] In some embodiments, the frame 110 has two air inlet windows 111 spaced apart along the first direction Y, each air inlet window 111 is provided with at least one corresponding blade 200, and the blade 200 of each air inlet window 111 can be switched between the shielding state and the air intake state in the air inlet window 111 where it is located. A support portion may be provided at the interval between the two air inlet windows 111, and the support portion is used to support the upper and lower sides of the frame 110 in the second direction Z. The two air inlet windows 111 may be equal in size so that the blades 200 or other accessories provided in the two air inlet windows 111 can be assembled with each other. The blades 200 in the two air inlet windows 111 may be symmetrically arranged along the support portion so as to simultaneously control the rotation of the active blades 230 in the two air inlet windows 111. Both air inlet windows 111 may have a plurality of blades 200, and a first limiting strip 220 is provided on the same side of the plurality of blades 200, and a second limiting strip 112 is provided on the side of the air inlet window 111 close to the blades 200 where the first limiting strip 220 is not provided. Thus, the second limiting strip 112 can limit the blade 200 close to it, and the blade 200 can limit the other blade 200 away from the second limiting strip 112 to prevent the blade 200 from over-rotating, so that the blade 200 can block the range surrounded by the side wall of the air intake window 111 in the shielding state. In addition, reinforcing ribs 113 are also provided between the decorative strips 120 of the two air intake windows 111 to enhance the stability of the decorative strips 120. The transmission members 300 of the two air intake windows 111 can be arranged at the interval between the two air intake windows 111 to simultaneously control the rotation of the blade 200. The mounting members of the two air intake windows 111 can be arranged on the side away from the respective transmission members 300.
[0053] In some embodiments, the air intake grille 10 includes a driving motor 400, which may be located between the two air intake windows 111 and connected to the frame 110. The driving motor 400 includes two output terminals 410, which are located on both sides of the driving motor 400 in the first direction Y. One output terminal 410 is connected to a corresponding blade 200 in an air intake window 111, so that the blades 200 in the two air intake windows 111 are driven by the driving motor 400 to switch between the shielding state and the air intake state. The support portion at the interval between the two air intake windows 111 and the side walls of the two air intake windows 111 close to the support portion form a groove for installing the driving motor 400. The driving motor 400 is fixed to the bottom of the groove. The two output ends 410 of the driving motor 400 are respectively fixedly connected to the rotating shafts of the active blades 230 in the two air inlet windows 111. The driving motor 400 drives the active blades 230 to rotate, and the active blades 230 drive the driven blades 240 to rotate through the transmission member 300, so that the driving motor 400 can simultaneously drive all the blades 200 of the two air inlet windows 111 to rotate, so that the blades 200 can block the passage of air in the shielding state, and the blades 200 can be hidden behind the decorative strips 120 in the air inlet direction X in the air inlet state. The degree of shielding of the air inlet window 111 by the blades 200 can also be controlled by controlling the rotation angle of the output end 410 of the driving motor 400. In this embodiment, the bottom and side walls of the groove can be provided with a plurality of receiving plates extending away from the bottom and the side walls, and the plurality of receiving plates can be respectively abutted against the side and bottom surfaces of the driving motor 400 to limit the driving motor 400. A circuit channel connected to the drive motor 400 may be provided on the receiving plate abutting against the bottom surface of the drive motor 400 , so as to facilitate the electrical connection between the drive motor 400 and the vehicle body.
[0054] To sum up, the blade 200 is arranged in sequence with the decorative strip 120 in the air intake direction X, so that the blade 200 can be located between the vehicle body and the decorative strip 120, and the blade 200 can be switched between the shielding state and the air intake state to achieve the effect of active air intake, and in the air intake state, the decorative strip 120 shields the blade 200 in the air intake direction X, thereby achieving the purpose of protecting the blade 200 and reducing the influence of the blade 200 on the air intake efficiency.
