Description

Technical Field

[0001] The utility model relates to the field of vehicle parts, and in particular to an active air intake grille and a vehicle. Background Art

[0002] The active air intake grille, especially the external active air intake grille, is an important part of the vehicle's appearance. It is located at the front of the vehicle and usually includes a frame, blades, an actuator and a connecting rod mechanism. The actuator drives the blades to move through the connecting rod mechanism to open or close the air intake on the frame. Specifically, when air intake heat dissipation is not required or wind resistance needs to be reduced, the air intake can be closed to prevent outside air from entering the vehicle cabin, causing the temperature inside the vehicle to rise and reducing the vehicle's driving resistance. When heat dissipation is required, the air intake can be fully or partially opened to control the air intake volume to meet different heat dissipation needs.

[0003] Since the existing active air intake grille is closed at the air intake, and when the vehicle is driving at high speed or wading through water, the blades are easily forced to flip or move to open the air intake under external impact such as airflow or water flow, and the torque generated by the blades under the action of the impact force will be transmitted to the actuator through the connecting rod mechanism, causing damage to the actuator.

The first link transmits the driving force to the third link through the second link arranged in a rotation manner. The third link, the fourth link, the fixed bracket and the fifth link constitute a quadrilateral force transmission mechanism. The fixed bracket is fixedly installed on the frame and remains stationary. That is, the third link and the fourth link jointly drive the fifth link to move relative to the fixed bracket, that is, the frame, and then drive the blade fixedly connected to the fifth link to move, so as to fully or partially open the air inlet; when the driving shaft rotates in the opposite direction, the air inlet can be closed to meet the use needs under different working conditions. At the same time, since when the blade closes the air inlet, the first connection point (that is, the connection point between the drive shaft and the first connecting rod), the second connection point (that is, the connection point between the second connecting rod and the first connecting rod), and the third connection point (that is, the connection point between the second connecting rod and the third connecting rod) are all located on the first straight line, and the first straight line is tangent to a circle with the fourth connection point (that is, the connection point between the third connecting rod and the fixed bracket) as the center and the distance between the fourth connection point and the third connection point as the radius. Then, when the blade is subjected to external impact, the impact force on the blade is transmitted to the third connecting rod through the fifth connecting rod, and the third connecting rod has a tendency to rotate around the fourth connection point relative to the fixed bracket. At this time, the motion of the third connection point on the third connecting rod is The direction of movement is the direction of the first straight line, that is, the direction of the force applied by the third link to the second link through the third connection point is the direction of the first straight line, and the first straight line passes through the second connection point and the first connection point, that is, the first straight line is parallel to the extension direction of the second link, so the second link cannot rotate under the action of the third link, that is, the third link only applies tension to the second link and the first link, and does not apply torsional force, that is, the third link cannot drive the second link and the first link to rotate. At this time, the connecting rod mechanism is equivalent to a self-locking state, which can make the blade always in a closed state under external impact, thereby realizing self-locking of the blade in the closed state, and since no torque is transmitted to the actuator, the actuator is not easily damaged.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "matched" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0035] In this document, a Y-axis is established, where the Y-axis represents the left and right directions of the vehicle, with the positive direction of the Y-axis representing the left side of the vehicle and the negative direction of the Y-axis representing the right side of the vehicle. It should be noted that the aforementioned Y-axis designation is merely for the purpose of facilitating and simplifying the description of the present invention, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be construed as limiting the present invention.

[0036] like Figure 1-Figure 7 As shown, an active air intake grille of an embodiment of the present invention includes a frame 1, a blade 2, a connecting rod mechanism 3, a fixed bracket 4 and an actuator 5, wherein the connecting rod mechanism 3 includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33, a fourth connecting rod 34 and a fifth connecting rod 35, the actuator 5 and the fixed bracket 4 are both mounted on the frame 1, the driving shaft 51 of the actuator 5 is fixedly connected to one end of the first connecting rod 31, and the two ends of the second connecting rod 32 are respectively connected to the other end of the first connecting rod 31 and the third connecting rod 35. The middle part of the connecting rod 33 is rotatably connected, and the two ends of the third connecting rod 33 are rotatably connected to the fixed bracket 4 and the fifth connecting rod 35 respectively. The two ends of the fourth connecting rod 34 are rotatably connected to the fixed bracket 4 and the fifth connecting rod 35 respectively. The third connecting rod 33, the fourth connecting rod 34, the fixed bracket 4 and the fifth connecting rod 35 constitute a quadrilateral force transmission mechanism. The fifth connecting rod 35 is fixedly connected to the blade 2. The frame 1 is provided with an air inlet 11, and the blade 2 is used to cover the air inlet 11.

[0037] Let the connection point between the drive shaft 51 and the first connecting rod 31 be the first connection point A, the connection point between the second connecting rod 32 and the first connecting rod 31 be the second connection point B, the connection point between the second connecting rod 32 and the third connecting rod 33 be the third connection point C, and the connection point between the third connecting rod 33 and the fixed bracket 4 be the fourth connection point D. When the blade 2 closes the air inlet 11, the first connection point A, the second connection point B and the third connection point C are all located on the first straight line L1, and the first straight line L1 is tangent to a circle with the fourth connection point D as the center and the distance between the fourth connection point D and the third connection point C as the radius.

[0038] Specifically, the active air intake grille can be an external active air intake grille. The frame 1 is located at the front of the vehicle and can be designed to match the relevant body structure. The frame 1 is provided with an air intake 11 extending generally in the left-right direction of the vehicle. The shape of the blades 2 matches the air intake 11 to ensure that the air intake 11 can be closed. The actuator 5 can receive relevant commands to rotate or stop the drive shaft 51.

[0039] The fixing bracket 4 is of any shape and is used to support and secure the linkage 3 to the frame 1. The two connecting rods in the linkage 3, which are rotatably connected to each other, are rotatably connected via a pin 36, providing a simple rotatable connection. The linkage 3 can be a planar linkage, meaning that the axes of all the pins 36 in the linkage 3 are parallel. The connecting rods of the linkage 3 can be straight or curved, allowing for flexible configuration as needed to avoid interference with other structures.

[0040] In this embodiment, the driving shaft 51 of the actuator 5 rotates to drive the first link 31 of the linkage 3 to rotate. The first link 31 transmits the driving force to the third link 33 through the second link 32 that is rotated. The third link 33, the fourth link 34, the fixed bracket 4 and the fifth link 35 constitute a quadrilateral force transmission mechanism. The fixed bracket 4 is fixedly mounted on the frame 1 and remains stationary. That is, the third link 33 and the fourth link 34 jointly drive the fifth link 35 to move relative to the fixed bracket 4, that is, the frame 1, and then drive the blade 2 fixedly connected to the fifth link 35 to move, so as to fully or partially open the air inlet 11. When the driving shaft 51 rotates in the opposite direction, the air inlet 11 can be closed to meet the use needs under different working conditions. At the same time, if Figure 7As shown, when the blade 2 closes the air inlet 11, the first connection point A (that is, the connection point between the drive shaft 51 and the first link 31), the second connection point B (that is, the connection point between the second link 32 and the first link 31), and the third connection point C (that is, the connection point between the second link 32 and the third link 33) are all located on the first straight line L1, and the first straight line L1 is tangent to a circle with the fourth connection point D (that is, the connection point between the third link 33 and the fixed bracket 4) as the center and the distance between the fourth connection point D and the third connection point C as the radius. Furthermore, when the blade 2 is subjected to external impact, the impact force on the blade 2 is transmitted to the third link 33 through the fifth link 35, and the third link 33 has a tendency to rotate around the fourth connection point D relative to the fixed bracket 4. At this time, the third connection point C on the third link 33 is at The movement trend direction is the direction of the first straight line L1, that is, the direction of the force applied by the third link 33 to the second link 32 through the third connection point C is the direction of the first straight line L1, and the first straight line L1 passes through the second connection point B and the first connection point A, that is, the first straight line L1 is parallel to the extension direction of the second link 32, so the second link 32 cannot rotate under the action of the third link 33, that is, the third link 33 only applies a pulling force to the second link 32 and the first link 31, and does not apply a torsional force, that is, the third link 33 cannot drive the second link 32 and the first link 31 to rotate. At this time, the connecting rod mechanism 3 is equivalent to a self-locking state, which can make the blade 2 always in a closed state under external impact, thereby realizing self-locking of the blade 2 in the closed state, and since no torque is transmitted to the actuator 5, the actuator 5 is not easily damaged.

[0041] like Figure 6-Figure 7 and Figure 11-12 As shown, optionally, when the blade 2 closes the air inlet 11, the first connection point A is located between the second connection point B and the third connection point C;

[0042] When the blade 2 fully opens the air inlet 11 , the first connection point A, the second connection point B, and the third connection point C are located on the second straight line L2 , and the first connection point A is located on a side of the second connection point B away from the third connection point C.

[0043] It should be noted that, since the positions of the connecting rods of the connecting rod mechanism 3 change in the process of the air inlet 11 changing from closed to fully open, even in the open state and the closed state of the air inlet 11, the first connection point A, the second connection point B and the third connection point C are all collinear, but the common straight line is no longer the same. For the sake of convenience in distinction, when the air inlet 11 is open, the common straight line of the first connection point A, the second connection point B and the third connection point C is recorded as the first straight line L1; when the blade 2 is closed, the common straight line of the first connection point A, the second connection point B and the third connection point C is recorded as the second straight line L2.

[0044] In this embodiment, when the air inlet 11 changes from a closed state to an open state, the connection point between the drive shaft 51 and the first connecting rod 31, that is, the first connection point A, changes from a position between the second connection point B and the third connection point C to a position on the side of the second connection point B away from the third connection point C, that is, the drive shaft 51 drives the first connecting rod 31 to rotate 180°, so that the blade 2 can be raised to the highest position to open the air inlet 11. During the process of the drive shaft 51 rotating 180° in the opposite direction, the blade 2 will gradually lower until the air inlet 11 is closed.

[0045] By making the blade 2 fully open the air inlet 11, the first connection point A, the second connection point B and the third connection point C are located on the second straight line L2, and the first connection point A is located on the side of the second connection point B away from the third connection point C, the movement stroke of the blade 2 can be controlled, avoiding the technical problem that when the air inlet 11 is in the open position, the blade 2 can continue to move upward because the first connection point A, the second connection point B and the third connection point C are not collinear, making the entire movement stroke of the blade too large and easy to interfere with other structures.

[0046] like Figure 4-Figure 12 As shown, optionally, the rotation axis of the first connecting rod 31 and the second connecting rod 32, the rotation axis of the second connecting rod 32 and the third connecting rod 33, the rotation axis of the third connecting rod 33 and the fifth connecting rod 35, the rotation axis of the third connecting rod 33 and the fixed bracket 4, the rotation axis of the fourth connecting rod 34 and the fifth connecting rod 35, and the rotation axis of the fourth connecting rod 34 and the fixed bracket 4 are all parallel to the axis of the drive shaft 51.

[0047] In this embodiment, the axes of each rotation axis and the drive shaft 51 are arranged along the Y direction, so that each connecting rod of the connecting rod mechanism 3 rotates around the Y axis, simplifying the movement process, reducing the degree of freedom of movement, and the position movement range of the blade 2 is smaller during the process of opening and closing the air inlet 11, reducing interference with other parts.

[0048] like Figure 4 As shown, optionally, the fixed bracket 4 includes a first fixed plate 41 and a second fixed plate 42 that are relatively arranged, the first connecting rod 31 is at least partially located between the first fixed plate 41 and the second fixed plate 42, the drive shaft 51 passes through the first fixed plate 41 to be rotatably connected to the first connecting rod 31, and the third connecting rod 33 and the fourth connecting rod 34 are both rotatably connected to the second fixed plate 42.

[0049] In this embodiment, the first and second fixing plates 41, 42 can be flat plates, spaced apart along the Y-axis. A drive shaft 51 passes through the first fixing plate 41 to connect with the first connecting rod 31. The drive shaft 51 is rotatable relative to the first fixing plate 41. While driving the first connecting rod 31 to rotate, the drive shaft 51 is supported by the first fixing plate 41, thereby improving the stability of the movement. Furthermore, the third and fourth connecting rods 33, 34 are rotatably connected to the second fixing plate 42 of the fixed bracket 4, and the drive shaft 51 is rotatably connected to the first fixing plate 41 of the fixed bracket 4. This arrangement of the connecting rods and the drive shaft 51 is more rational, and the force applied to the fixed bracket 4 is more even.

[0050] like Figure 5 and Figure 8 As shown, optionally, the third connecting rod 33 is located on a side of the second fixing plate 42 close to the first fixing plate 41 , and the fourth connecting rod 34 is located on a side of the second fixing plate 42 away from the first fixing plate 41 .

[0051] In this embodiment, because the third link, fourth link 34, fifth link 35, and second fixing plate 42 form a quadrilateral force transmission structure, and the third link 33 and fourth link 34 move in substantially the same direction, by positioning the third link 33 and fourth link 34 on either side of the second fixing plate 42, motion interference between the third link 33 and fourth link 34 is avoided. Furthermore, the third link 33 and fourth link 34, which are rotatably connected to the second fixing plate 42, are positioned on either side of the second fixing plate 42, thereby improving force uniformity on the second fixing plate 42.

[0052] like Figure 4 As shown, optionally, the fixing bracket 4 further includes a third fixing plate 43 , the third fixing plate 43 is connected between one end of the first fixing plate 41 and the second fixing plate 42 , and the third fixing plate 43 is connected to the frame 1 .

[0053] In this embodiment, the first fixing plate 41, the second fixing plate 42 and the third fixing plate 43 are enclosed to form a U-shaped structure, and the relevant connecting rods of the connecting rod mechanism 3 are installed in the U-shaped space of the U-shaped structure. By providing a connecting hole on the bottom of the U-shaped structure, that is, the third fixing plate 43, bolts are passed through the connecting hole and the frame 1 to achieve the connection between the fixing bracket 4 and the frame 1, and the installation of the fixing bracket 4 is more stable.

[0054] like Figure 4As shown, optionally, the fifth connecting rod 35 includes a rod body 351 and a blade fixing plate 352, one end of the rod body 351 is rotatably connected to the third connecting rod 33, the other end of the rod body 351 is connected to the blade fixing plate 352, the blade fixing plate 352 is connected to the blade 2, and the middle part of the rod body 351 is rotatably connected to the fourth connecting rod 34.

[0055] In this embodiment, the rod body 351 can be an elongated structure. By providing a blade fixing plate 352 at one end of the rod body 351, the blade fixing plate 352 can be connected parallel to the blade 2, thereby increasing the contact area between the fifth connecting rod 35 and the blade 2 and ensuring the stability of the connection between the fifth connecting rod 35 and the blade 2. The blade fixing plate 352 can be provided with a connecting hole, through which the fastener 7 is inserted to fix the fifth connecting rod 35 to the blade 2, simplifying installation.

[0056] like Figure 1-Figure 3 As shown, optionally, the active air intake grille also includes a baffle 6, the connecting rod mechanism 3, the fixed bracket 4, the actuator 5 and the baffle 6 are all located on the side of the frame 1 facing the interior of the vehicle, and the baffle 6 blocks part of the air intake 11, and the fixed bracket 4 and the actuator 5 are located on the side of the baffle 6 away from the air intake 11.

[0057] In this embodiment, the connecting rod mechanism 3, the fixing bracket 4, the actuator 5 and the shielding plate 6 are all arranged on the side of the frame 1 facing the interior of the vehicle. On the one hand, the connecting rod mechanism 3, the fixing bracket 4 and the actuator 5 can be protected; on the other hand, the external shape of the vehicle is not affected and the wind resistance is reduced.

[0058] The fixed bracket 4 and the actuator 5 are located on the side of the baffle plate 6 away from the air inlet 11. The baffle plate 6 is used to shield the fixed bracket 4 and the actuator 5 to prevent the fixed bracket 4 and the actuator 5 from being exposed at the air inlet 11, and the connecting rod mechanism 3 can be hidden to the back of the blade 2 during movement. In this way, when people stand outside the vehicle and look at the active air intake grille, the connecting rod mechanism 3, the fixed bracket 4 and the actuator 5 are basically completely shielded, which makes it more aesthetically pleasing. At the same time, it can also provide better protection for the actuator 5 to prevent flying stones and sand from hitting the actuator 5 and damaging it.

[0059] like Figure 2-Figure 3 As shown, optionally, the baffle 6 is fixedly connected to the frame 1, and the baffle 6 includes a first baffle 61 and a second baffle 62 that are connected to each other and arranged at an angle to each other, the fixed bracket 4 is installed on the first baffle 61, and the actuator 5 is installed on the second baffle 62, and the connecting rod mechanism 3 is arranged from the rear of the vehicle to the front of the vehicle from the side of the first baffle 61 away from the second baffle 62, and is connected to the blade 2.

[0060] In this embodiment, the baffle plate 6 is fixedly connected to the frame 1, and the third fixing plate 43 of the fixing bracket 4 is installed on the first baffle 61 of the baffle plate 6, and the actuator 5 is installed on the second baffle 62, thereby realizing the fixed installation of the fixing bracket 4 and the actuator 5 relative to the frame 1.

[0061] Furthermore, one Y-axis end of the first baffle 61 is connected to the second baffle 62. The first and second baffles 61 and 62 are connected to form an L-shaped space. The actuator 5 and the fixing bracket 4 are both located within the L-shaped space, effectively enclosing the actuator 5 and the fixing bracket 4. Simultaneously, the connecting rod mechanism 3 can also move within the space on the side of the first baffle 61 away from the second baffle 62, and can move from the rear of the vehicle to the front of the vehicle to connect with the blade 2. This shielding plate 6 ensures smooth movement of the connecting rod mechanism 3 while providing shielding protection for the fixing bracket 4 and the actuator 5.

[0062] Another embodiment of the present invention provides a car including the above-mentioned active air intake grille. The advantages of the car described in this embodiment over the prior art are the same as those of the above-mentioned active air intake grille, and will not be repeated here.

[0063] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
