[0039] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] The embodiment of the present invention provides a motor vehicle air outlet grille, such as Figure 1 and Figure 2 As shown, including:

[0041] Frame 1;

[0042] A plurality of blade setting seats 2 are symmetrically arranged in pairs on two side frames of the frame 1;

[0043] Two ends of a plurality of air outlet blades 3 are rotatably connected to the blade setting seat 2 respectively.

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] The two ends of the air outlet blade 3 are respectively connected to a blade setting seat 2, and the air outlet blade 3 can rotate on the blade setting seat 2; when the air outlet angle needs to be adjusted, each air outlet blade 3 can be moved; when the air outlet blade 3 is moved to be parallel to the plane of the frame 1, the air outlet will be blocked; the number of air outlet blades 3 that block the air outlet can be adjusted to adjust the ventilation volume. In addition, when cleaning, all the air outlet blades 3 are adjusted to a position parallel to the plane of the frame 1, and then the back of the air outlet blade 3 is adjusted out, and only two adjustments are needed to complete the cleaning of the air outlet grille.

[0046] In the motor vehicle air outlet grille of the present invention, the air outlet blades 3 rotate on the blade setting seat 2; the angle of each air outlet blade 3 can be adjusted according to demand, so that the air outlet angle and ventilation volume of the air outlet grille can be freely changed. When the air outlet blades 3 are rotated to a position parallel to the plane of the frame 1, it is convenient to clean the dust on the surface of the air outlet blades 3.

[0047] In one embodiment, Figure 1 As shown, the air outlet blade 3 includes:

[0048] The body 3-2 is in the shape of a long strip;

[0049] The two blade shafts 3 - 1 are rotatably connected to the two ends of the body 3 - 2 respectively; the blade shaft 3 - 1 is rotatably connected to the blade setting seat 2 .

[0050] The working principle and beneficial effects of the above technical solution are:

[0051] The body 3-2 of the air outlet blade 3 is arranged in a long strip shape, so that when the air outlet grille is not in use, the blade can block the air outlet area of ​​the air outlet grille. The blade shaft 3-1 is used to set the blade on the blade setting seat 2; the rotation setting between the blade shaft 3-1 and the body 3-2 is convenient for adjusting the angle of the body 3-2 and thus adjusting the air outlet angle of the air outlet grille; on the other hand, when the air outlet blade 3 is damaged, only the body 3-2 needs to be replaced, which improves the replacement efficiency and replacement cost.

[0052] In one embodiment, Figure 3 As shown, plug holes 3-4 for accommodating the blade shaft 3-1 are provided at both ends of the body 3-2; a plurality of limit devices 3-3 are evenly provided on the side walls of the plug holes 3-4; the limit devices 3-3 include: a limit groove 3-31, a ball 3-33 and a limit spring 3-32;

[0053] The limiting groove 3-31 is arranged on the side wall of the plug hole 3-4;

[0054] The ball 3-33 is arranged in the limiting groove 3-31; a groove 3-11 is arranged on the side of the blade shaft 3-1 at a position corresponding to the limiting groove 3-31, and two adjacent grooves 3-11 are connected through a channel 3-12;

[0055] The limiting spring 3-32 is arranged between the ball 3-33 and the bottom of the limiting groove 3-31; one end of the limiting spring 3-32 is fixedly connected to the bottom of the limiting groove 3-31, and the other end is in contact with the ball 3-33.

[0056] The working principle and beneficial effects of the above technical solution are:

[0057] When the blade shaft 3-1 and the body 3-2 rotate, the ball 3-33 will move into the limit groove 3-31 under the push of the blade shaft 3-1, and when it reaches the position of the next groove 3-11, the ball 3-33 will push against the groove 3-11 under the action of the restoring force of the limit spring 3-32. The channel 3-12 between the grooves 3-11 facilitates the ball 3-33 to reach another groove 3-11 from one groove 3-11, and ensures that the blade shaft 3-1 and the body 3-2 will not slip during the rotation process. By passing a plurality of limit devices 3-3 between the blade shaft 3-1 and the body 3-2, it is prevented that the wind force drives the body 3-2 to rotate on the blade shaft 3-1.

[0058] In one embodiment, Figure 3 As shown, the blade setting seat 2 includes:

[0059] Base 2-1, the bottom end of which is fixedly connected to frame 1;

[0060] The connecting body 2-3 has a blade setting hole 2-4 in the middle; the blade setting hole 2-4 is used for rotationally connecting with the air outlet blade 3;

[0061] The limiting body 2-5 is U-shaped, and the two ends of the limiting body 2-5 respectively pass through the connecting body 2-3 and are fixedly connected to the base 2-1; the connecting body 2-3 can slide up and down between the limiting body 2-5 and the base 2-1; a connecting spring 2-2 is respectively arranged between the connecting body 2-3 and the base 2-1 and on both sides of the limiting body 2-5; one end of the connecting spring 2-2 is fixedly connected to the connecting body 2-3; and the other end is fixedly connected to the base 2-1; the two ends of the limiting body 2-5 are located on both sides of the blade setting hole 2-4.

[0062] The working principle and beneficial effects of the above technical solution are:

[0063] The blade setting seat 2 sets the air outlet blade 3 on the air outlet area of ​​the air outlet grille, and the air outlet angle is adjusted by adjusting the angle of the air outlet blade 3. When the wind force is too strong, the air outlet blade 3 is easily deformed due to the obstruction of the air outlet blade 3. The air outlet blade 3 is buffered by the sliding of the connecting body 2-3 and the limiting body 2-5. The air outlet blade 3 is staggered with other blades under the blowing of the wind, and the wind flows out from the gap between the air outlet blade 3 and other blades, so as to achieve the effect of removing part of the wind force. When the wind force is restored, the connecting spring 2-2 pulls the connecting body 2-3 to realize the reset of the air outlet blade 3. The air outlet blade 3 can be a curved blade.

[0064] In one embodiment, the heights of the limiting bodies 2-5 of the two corresponding blade setting seats 2 are the same; the height of the limiting bodies 2-5 of the blade setting seats 2 in the middle part on the same side of the frame 1 is greater than the height of the limiting bodies 2-5 of the blade setting seats 2 in the head and tail parts.

[0065] The working principle and beneficial effects of the above technical solution:

[0066] The heights of the limiting bodies 2-5 of the two corresponding blade setting seats 2 are the same, ensuring that the air outlet blades 3 are installed on a plane horizontal to the frame 1. The limiting bodies 2-5 on the same side have their height components reduced from the middle to both sides. When the wind force blows all the air outlet blades 3 to the highest position of the limiting bodies 2-5, all the air outlet blades 3 form an arc surface, increasing the size of the air outlet surface, which protects the air outlet blades 3 on the one hand and ensures smooth air outlet on the other hand.

[0067] In one embodiment, Figure 1 and Figure 5As shown, the motor vehicle air outlet grille also includes: a first gear 7 and a second gear 6 arranged in the frame 1, the first gear 7 is fixedly arranged at one end of the air outlet blade 3, and the second gear 6 is transmission-connected between two adjacent first gears 7; a transmission motor 9 is arranged in the frame 1, and a third gear 8 is arranged at its output end; the third gear 8 is meshed with the first gear 7 at the head end or the tail end.

[0068] The working principle and beneficial effects of the above technical solution are:

[0069] Through the transmission connection among the first gear 7, the second gear 6 and the third gear 8 in the above solution, the transmission motor 9 drives the air outlet blades 3 to rotate, thereby adjusting the air outlet angle.

[0070] In one embodiment, Figure 1 and Figure 6 As shown, a blade alignment device 5 is provided on a side frame of the frame 1; the blade alignment device 5 is provided between the blade setting seat 2 and the body 3-2, and is located on the side of the air outlet blade 3 away from the first gear 7; the blade alignment device 5 is located below the blade shaft 3-1.

[0071] The blade correcting device 5 comprises:

[0072] The adjusting body 5-2 is arranged between the blade setting seat 2 and the body 3-2, and is located on the side of the air outlet blade 3 away from the first gear 7; the adjusting body 5-2 is located below the blade shaft 3-1; a plurality of adjusting posts 5-1 are arranged on the side of the adjusting body 5-2 close to the body 3-2, and the adjusting posts 5-1 correspond to the body 3-2 one by one;

[0073] Two reset mechanisms are arranged at two ends of the adjusting body 5 - 2 and are used to reset the adjusting body 5 - 2 .

[0074] The reset mechanism includes: an iron core 5-3, a coil 5-5 and a reset spring 5-4;

[0075] One end of the iron core 5-3 is fixedly connected to the adjusting body 5-2, and the other end is sleeved in the coil 5-5; the return spring 5-4 is sleeved outside the iron core 5-3 and located between the coil 5-5 and the adjusting body 5-2.

[0076] The motor vehicle air outlet grille also includes: a controller 4, which is arranged in the frame 1 and is electrically connected to the transmission motor 9 and the coil 5-5, and is used to control the on-off of the current in the coil 5-5 and the operation of the transmission motor 9.

[0077] The working principle and beneficial effects of the above technical solution are:

[0078] Since the body 3 - 2 and the blade shaft 3 - 1 of the air outlet blade 3 are rotatably connected, the air outlet angle of each air outlet blade 3 can be manually set individually to ensure that the air outlet angle is set according to demand. When the wind sweeping mode is needed, the wind sweeping effect is very poor due to the different wind outlet angles of the air outlet blades 3; the angle between the main body 3-2 and the blade shaft 3-1 needs to be adjusted; when adjusting, the coil 5-5 is energized, the coil 5-5 generates magnetism, attracts the iron core 5-3 to move into the coil 5-5, thereby driving the adjusting body 5-2 to move in the direction of the main body 3-2, so that the adjusting post 5-1 is located below the main body 3-2 to block the main body 3-2, and the transmission motor 9 drives the air outlet blade 3 to rotate, so that the main body 3-2 of the air outlet blade 3 will stay at the position where the adjusting post 5-1 contacts due to the obstruction of the adjusting post 5-1, and then, the coil 5-5 is de-energized, the adjusting body 5-2 is reset under the action of the reset spring 5-4, and the adjusting post 5-1 is removed from under the main body 3-2; when the transmission motor 9 drives the air outlet blade 3 to rotate again, the angle of the main body 3-2 of each blade is consistent, so that the wind sweeping mode is used. The controller 4 controls the on-off of the current in the coil 5 - 5 and the operation of the transmission motor 9 ; the controller 4 includes a single chip microcomputer.

[0079] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
