[0041] The present application embodiment provides a vehicle. Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application. The vehicle 1 includes a central control screen 2, a dashboard 3 and an air outlet device 4.

[0042] The central control screen 2 is a larger screen, such as a 12-inch, 14-inch or even 16-inch screen. Figure 1 As shown, the air outlet device 4 is arranged on the instrument panel 3, and the air outlet of the air outlet device 4 faces the central control screen 2. The air outlet device is matched with the instrument panel 3 to realize an overall simple panel structure, which is compact and beautiful.

[0043] like Figure 2 As shown, Figure 2 Another structural schematic diagram of a vehicle provided in an embodiment of the present application. The vehicle 1 further includes a speaker panel 5. The air outlet device 4 overlaps with the speaker panel 5, so that the position of more complex modeling lines can be concentrated.

[0044] The structure of the air outlet device 4 is described in detail below. Figure 1 The air outlet device 4 includes a shell 41 , an air outlet frame 42 , an internal cavity 43 and a blade assembly 44 .

[0045] The internal cavity 43 is formed by connecting the air outlet frame 42 and the shell 41. Figure 2 As shown, the width direction of the internal cavity 43 is the first direction y, the length direction is the second direction x, and the height direction is the third direction z.

[0046] like Figure 1As shown, the air outlet frame 42 forms the air outlet of the air outlet device 4. The air outlet frame 42 includes: a lower frame 421 and an upper frame 422. The upper frame 422 is arranged above the lower frame 421. The upper frame 422 includes a connecting section 4221. The connecting section 4221 connects the lower frame 421. The shape of the connecting section 4221 is a concave arc shape, which can improve the visual effect of the air outlet device 4. It should be noted that the air outlet frame 42 can be made by an integrated molding process.

[0047] The blade assembly 44 includes a first blade group 441. The first blade group 441 is used to control the height of the airflow. The blades in the first blade group 441 are fixed to the inner side of the housing 41 and are a non-adjustable structure. The blades in the first blade group 441 are arc-shaped blades, and the opening direction of the arc-shaped blades is toward the air outlet. The height direction of the airflow can be fixed by the curvature of the arc-shaped blades. The lower end of the arc-shaped blade fits the incoming flow direction, and the upper end is the outlet direction. The airflow can change direction along the curvature of the arc-shaped blade, thereby reducing the pressure loss caused by the change in wind direction.

[0048] Please refer to Figure 1 and Figure 3 , the first blade group 441 includes at least one first blade 4411, and the number of the first blades 4411 can be selected according to the actual air outlet demand. In the embodiment of the present application, the number of the first blades 4411 is not limited. The first blade 4411 is arranged in the internal cavity 43, and the first blade 4411 is arranged along the first direction y. The first blade 4411 is a blade of a segmented structure, including: a first blade segment 44111 and a second blade segment 44112. Among them, the second blade segment 44112 is arranged on both sides of the first blade segment 44111, and the second blade segment 44112 is arranged opposite to the connecting segment 4221. The second blade segment 44112 is concave relative to the first blade segment 44111 to increase the air outlet gap between the second blade segment 44112 and the connecting segment 4221.

[0049] In one embodiment, the first blade group 441 also includes at least one second blade 4412, and the number of the second blades 4412 can be selected according to the actual air outlet demand. In the embodiment of the present application, the number of the second blades 4412 is not limited. The second blade 4412 is arranged in the internal cavity 43, and the second blade 4412 and the first blade 4411 are arranged in parallel in the second direction. The second blade 4412 is close to the lower frame 421 relative to the first blade 4411. The second blade 4412 is a segmented structure blade, including: a third blade segment 44121 and a fourth blade segment 44122. Among them, the fourth blade segment 44122 is arranged on both sides of the third blade segment 44121, and the lower end of the third blade segment 44121 is provided with a recess 441211, and the opening of the recess 441211 faces the lower frame 421. The depth of the recess 441211 is relatively shallow, which not only ensures the continuity of the curvature of the second blade 4412 from the top perspective, but also expands the gap between the second blade 4412 and the front shell 411, thereby increasing the air volume. Furthermore, it can also make the vertically blown airflow blow slightly higher, so that the airflow is not blocked by the central control screen 2.

[0050] Please refer to Figure 2 and Figure 3 , the blade assembly 44 also includes: a second blade group 442. The second blade group 442 is used to control the left and right flow direction of the airflow. The second blade group 442 includes: a plurality of third blades 4421. The plurality of third blades 4421 are arranged below the first blade group 441, and the plurality of third blades 4421 are arranged in parallel along the first direction y. The third blade 4421 is a rotatable blade. When the third blade 4421 rotates to a state perpendicular to the first direction y, the airflow can be blown out vertically. At this time, the blowing device 4 can realize the people-avoiding blowing mode, which is used for the overall cooling of the crew cabin in the vehicle. When the third blade 4421 rotates to the extreme angle state, the airflow can be deviated to the outside of the air outlet along the second direction x and blow toward the occupant, so that the blowing device 4 realizes the occupant focusing mode.

[0051] In one embodiment, the boundary line between the first blade segment 44111 and the second blade segment 44112 is located outside the outermost third blade, and the outermost third blade is the blade closest to the air outlet frame along the first direction among the plurality of third blades 4421. Figure 4, the first blade 4411 includes a first blade segment 44111, and second blade segments 44112a and 44112b arranged on both sides of the first blade segment 44111. The second blade group 442 includes third blades 4421a-4421h arranged in parallel along the first direction y. The outermost third blades closest to the air outlet frame 42 along the first direction y are 4421a and 4421h, and the dividing line A1 between the second blade segment 44112a and the first blade segment 44111 is located on the outside of the third blade 4421a, and the dividing line A2 between the second blade segment 44112b and the first blade segment 44111 is located on the outside of the third blade 4421h.

[0052] In one embodiment, the boundary between the third blade segment 44121 and the corresponding fourth blade segment 44122 is located between the two corresponding innermost third blades 4421, and the two corresponding innermost third blades 4421 are the blades closest to the air outlet frame 42 along the first direction among the plurality of third blades 4421 corresponding to the corresponding fourth blade segment 44122. Figure 4 As shown, the second blade includes a third blade segment 44121, and two fourth blade segments 44122a and 44122b arranged on both sides of the third blade segment 44121. The third blade segment 44121 and the fourth blade segment 44122a correspond to the third blades 4421a-4421d, and the third blade segment 44121 and the fourth blade segment 44122b correspond to the third blades 4421e-4421f. Since the two innermost third blades corresponding to the third blade segment 44121 and the fourth blade segment 44122a are 4421c and 4421d, the dividing line B1 between the third blade segment 44121 and the fourth blade segment 44122a is arranged between the third blades 4421c and 4421d. Since the two innermost third blades corresponding to the third blade segment 44121 and the fourth blade segment 44122b are 4421e and 4421f, the boundary line B2 between the third blade segment 44121 and the fourth blade segment 44122b is set between the third blades 4421e and 4421f.

[0053] In one embodiment, the angle between the upper end of the first blade 4411 and the second direction x can be set to be smaller than the angle between the upper end of the second blade 4412 and the second direction x, so that the direction of the core airflow of the air outlet device 4 is slightly higher than the central control screen 2. Figure 2 As shown, the angle α between the upper end of the first blade 4411 and the second direction x is set to 5 degrees, and the angle β between the upper end of the second blade 4412 and the second direction x is set to 10 degrees.

[0054] In one embodiment, the angle between the lower ends of the first blade 4411 and the second blade 4412 and the third direction z may be set to be no greater than a first preset angle. The first preset angle may be 15 degrees. This allows the airflow inside the air outlet device 4 that originally travels along the third direction z to move more closely along the direction of the blades, thereby reducing pressure loss. For example, Figure 2 As shown, the angle γ between the lower end of the first blade 4411 and the third direction z is set to 10 degrees, and the angle θ between the lower end of the second blade 4412 and the third direction z is set to 15 degrees.

[0055] It should be noted that, although the first blade 4411 and the second blade 4412 adopt a segmented structure, they can be manufactured by an integrated molding process. Figure 5 As shown, when the wind direction inside the air outlet device 4 is vertically upward, after passing through the blade assembly 44 having the above structure, the wind direction of the air outlet changes to 80 degrees, so that the wind is focused on the human face.

[0056] The housing 41 includes a front housing 411 and a rear housing 412. The front housing 411 includes an outlet section near the air outlet frame 42. Figure 2 As shown, the outlet section of the front shell 411 close to the air outlet frame 42 is the first outlet section 4111. The angle between the first outlet section 4111 and the z direction is between 25 degrees and 55 degrees. Figure 2 As shown, the included angle m between the first outlet section 4111 and the z direction is 52 degrees.

[0057] Since when the angle between the first outlet section 4111 and the z-direction is less than 25 degrees, the direction of the airflow blown out from the gap between the front shell 411 and the second blade 4412 cannot be generally upward, and therefore it is not possible to lift the core airflow of the air outlet. When the angle between the first outlet section 4111 and the z-direction is greater than 52 degrees, the airflow cannot overlap, causing part of the airflow to blow onto the front windshield of the vehicle, increasing the risk of fogging of the front windshield. In summary, in the embodiment of the present application, by setting the angle between the first outlet section 4111 and the z-direction to between 25 and 55 degrees, the direction of the airflow blown out from the gap between the front shell 411 and the second blade 4412 is upward, and the core airflow of the air outlet is lifted. In one embodiment, the angle between the first outlet section 4111 and the z-direction can be set to 40 degrees, so that the core airflow of the air outlet has both a higher height and can achieve overlap.

[0058] The rear housing 412 includes an outlet section close to the air outlet frame 42. Figure 2As shown, the outlet section of the rear housing close to the air outlet frame 42 is the second outlet section 4121, and the angle between the second outlet section 4121 and the x direction is not greater than the second preset angle. In one embodiment, the second preset angle can be 8 degrees, and the extension line of the second outlet section 4121 is tangent to the upper end of the central control screen 2, so that the airflow blown by the air outlet device 4 can be blown from the upper end of the central control screen 2 to the face of the person, thereby avoiding the airflow being blocked by the central control screen. For example, Figure 2 As shown, the included angle k between the second outlet section 4121 and the x-direction is 8 degrees.

[0059] like Figure 2-4 As shown, the air outlet device 4 further includes a protruding structure 45, one end of which is fixed to the blades of the first blade group 441, and the other end of which is suspended in the air. The protruding structure 45 can prevent small objects such as coins from falling from the air outlet of the air outlet device 4.

[0060] When the first blade group 441 includes at least one first blade 4411 and at least one second blade 4412, and the first blade 4411 and the second blade 4412 are arranged alternately, a plurality of protrusion structures 45 may be arranged on a side of the first blade 4411 away from the second blade 4412, and a plurality of protrusion structures 45 may be arranged on both sides of the second blade 4412 close to and away from the first blade 4411. Similarly, a plurality of protrusion structures 45 may be arranged on a side of the second blade 4412 away from the first blade 4411, and a plurality of protrusion structures 45 may be arranged on both sides of the first blade 4411 close to and away from the second blade 4412. Further, a plurality of protrusion structures 45 evenly arranged at a first pitch may be provided on a side of the first blade 4411 away from the second blade 4412 and a side of the second blade 4412 away from the first blade 4411, and a plurality of protrusion structures 45 evenly arranged at a second pitch may be provided on a side of the first blade 4411 close to the second blade 4412 and a side of the second blade 4412 close to the first blade 4411, and the protrusion structures on the side where the second blade 4412 and the first blade 4411 are close to each other are arranged alternately. The first pitch is smaller than the second pitch, and in one embodiment, the second pitch is twice the first pitch.

[0061] In one embodiment, the protruding structure 45 is located directly above the corresponding third blade 4421 in the third direction z. When the corresponding third blade 4421 is in the second direction x, the protruding structure 45 blocks the corresponding third blade 4421 in the third direction z.

[0062] The air outlet device and vehicle provided in the embodiment of the present application include: a shell, an air outlet frame, an internal cavity and a blade assembly; the internal cavity is formed by the air outlet frame connected to the shell, and the width direction of the internal cavity is a first direction; the air outlet frame forms the air outlet of the air outlet device, and the air outlet frame includes an upper frame; and the blade assembly includes: a first blade group, the first blade group includes: a first blade, the first blade is arranged in the internal cavity, the first blade is arranged along the first direction, the first blade includes: a first blade segment; and a second blade segment, the second blade segment is arranged on both sides of the first blade segment, and the second blade segment is concave relative to the first blade segment to increase the air outlet gap between the second blade segment and the upper frame. The above scheme can increase the air outlet gap between the second blade segment and the upper frame by setting the first blade into a segmented structure so that the second blade segment inside it is concave relative to the first blade segment, so that the airflow is easier to blow toward the face of the occupant, thereby improving the efficiency of the air outlet.
