Description

air outlet structure

Technical Field

The invention relates to automotive interior trim, in particular to an air outlet structure.

Background

There is an increasing demand for motor vehicles, and at the same time, there is an increasing personalization. For example, it is desirable for various components and devices present in the vehicle cabin to perform additional functions or effects, such as air conditioning of the interior of the vehicle cabin, in addition to their original functions.

For this purpose, the motor vehicle has an air conditioning system for heating or cooling air and supplying the hot air or the cold air to the cabin interior space through an air outlet structure.

Fig. 14 shows a common air outlet structure, which includes a housing 1 ', a horizontal blade assembly 2', a vertical blade 3 'and a damper 4', wherein the horizontal blade assembly 2 'is installed at the front end of the housing 1' through a panel 11 ', the vertical blade 3' is installed at the middle of the housing 1 'through a bracket 12', and the damper 4 'is installed at the rear end of the housing 1'. In addition, a toggle button 5 ' is installed on one blade in the middle of the horizontal blade assembly 2 ', the vertical toggle of the toggle button 5 ' can drive the horizontal blade assembly 2 ' to rotate, the left-right toggle of the toggle button 5 ' can drive the vertical blade assembly 3 ' to rotate, and the opening and closing of the air door 4 ' are realized through other structures.

obviously, since the vertical blade 3 'is driven by the left and right poking of the poking button 5', this results in a large layout space, which is not suitable for a space-constrained environment. Moreover, since the toggle button 5 'is installed on a blade in the middle of the horizontal blade assembly 2', the structure occupies a certain space, and can shield the blowing to influence the blowing effect.

Moreover, as shown in fig. 14, since the outlet is narrow, the outlet structure further includes a follower blade 6' mounted on the hidden blade for optimizing the wind guiding effect. In general, in order to arrange the follower blades 6 ', the front ends of the vertical blades 3 ' need to be partially cut off, which affects the wind guiding of the vertical blades 3 '. In order to avoid cutting off a large part of the vertical blades 3 ', it is also generally necessary to move the vertical blades 3' back as a whole, which in turn requires an increased space for the housing, which is less suitable for a space-demanding environment.

The shifter assembly 5 further includes a vertical drum connecting gear 55 and a vertical drum switching gear 56, wherein the vertical drum connecting gear 55 is partially connected to the vertical blade drum 31 through the partition wall 13 (see fig. 9c), the vertical drum switching gear 56 is rotatably mounted on the corresponding mounting shaft 134 of the partition wall 13, the vertical drum switching gear 56 is engaged with the second tooth 541 of the horizontal blade driving gear 54, and the vertical drum connecting gear 55 is engaged with the vertical drum switching gear 56 (see fig. 9e, 10c, 11c and 12c), so that the rotation of the vertical drum switching gear 56, and thus the vertical drum connecting gear 55, and finally the vertical blade drum 31, can be driven by the rotation of the horizontal blade driving gear 54. Specifically, by the arrangement of the vertical drum changeover gear 56, the vertical blade drum 31 is rotated in the direction opposite to the rotation direction of the horizontal blades 22, 23, 24.

When the shift lever 53 is rotated, the rotating sleeve 52 is rotated, and the vertical blades 32, 33, 34, 35, 36, 37 are rotated by the vertical blade driving link 39 connected to the rotating sleeve 52; when the dial 53 is toggled up and down in the vertical direction, the toggle sleeve 51 is driven to rotate, and the vertical blade driving gear 54 connected to the toggle sleeve 51 drives the vertical drum connecting gear 55 and simultaneously drives the vertical blade drum 31 and the horizontal blades 22, 23, 24 to rotate. The engagement of the ball socket 392 of the vertical blade drive link 39 with the ball head 521 of the rotary sleeve 52 renders the vertical blades 32, 33, 34, 35, 36, 37 unaffected by dial-up and down, while the engagement of the ball head 441 of the damper drive link 44 with the ball socket 531 of the dial-up and down lever 53 (see fig. 9d) renders the first damper 41 and the second damper 42 unaffected by rotation and dial-up and down of the lever 53.

As shown in fig. 9a, when the lever 53 is in the initial position, the horizontal blades 22, 23, 24 are in the horizontal position, and only one horizontal blade 23 is visible to the passenger; as shown in fig. 9b, the vertical vane rotor 31 is not rotated, and the first damper 41 and the second damper 42 are in a closed state; as shown in fig. 9c, the vertical blades 32, 33, 34, 35, 36, 37 are in the initial position; as shown in fig. 9 d-9 e, the shaft 262 of the horizontal blade driving link 26 is in the middle position of the first chute 131.

as shown in fig. 10a to 10c, when the lever 53 is pulled out, the damper rack 43 is moved by the damper driving link 44 connected to the lever 53, and then the first damper 41 is controlled to rotate counterclockwise and the second damper 42 is controlled to open clockwise by the engagement of the upper rack 431 and the lower rack 432 on the damper rack 43 and the first gear 411 and the second gear 421 on the first damper 41 and the second damper 42, respectively. The extraction stroke of the lever 53 is freely adjustable to control the opening degrees of the first damper 41 and the second damper 42. When the dial 53 is dialed down, the dial sleeve 51 is driven to rotate counterclockwise, the horizontal blade driving gear 54 rotates clockwise, the shaft 262 moves from the middle position to the high position in the first sliding groove 131, the horizontal blades 22, 23 and 24 deflect upwards around the left shaft 27 and the right shaft 28 to realize downward inclination of the horizontal blades 22, 23 and 24 compared with the horizontal position, and the passengers can see the horizontal blades 23 and 24. Meanwhile, the horizontal blade driving gear 54 drives the vertical drum connecting gear 55 to rotate clockwise through the vertical drum switching gear 56, and then drives the vertical blade drum 31 to tilt upward relative to the horizontal position. So, can realize the effect of blowing downwards of air outlet. Conversely, when the toggle lever 53 is toggled up, as shown in fig. 11 a-11 c, the toggle sleeve 51 is rotated clockwise, the horizontal blade driving gear 54 rotates counterclockwise, so that the shaft 262 moves from the middle position to the low position in the first sliding slot 131, the horizontal blades 22, 23, 24 deflect downward around the left shaft 27 and the right shaft 28 to tilt the horizontal blades 22, 23, 24 upward compared to the horizontal position, and the passengers can see the horizontal blades 22, 23. At the same time, the horizontal blade driving gear 54 drives the vertical drum connecting gear 55 to rotate counterclockwise through the vertical drum switching gear 56, and then drives the vertical blade drum 31 to tilt downward with respect to the horizontal position. So, can realize the air outlet effect of blowing upwards. .

As shown in fig. 12 a-12 c, when the lever 53 is rotated clockwise, the ball 521 on the rotating sleeve 52 is driven to rotate clockwise, and the vertical blade linkage link 38 is driven to move leftward by the cooperation of the ball 521 and the ball socket 392, so that the vertical blades 32, 33, 34, 35, 36, 37 swing rightward. On the contrary, as shown in fig. 13 a-13 c, when the lever 53 is rotated counterclockwise, the ball 521 on the rotating sleeve 52 is driven to rotate counterclockwise, and the vertical vane linkage link 38 is driven to move rightward by the cooperation of the ball 521 and the ball socket 392, so that the vertical vanes 32, 33, 34, 35, 36, 37 swing leftward.

the above embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and various changes may be made in the above embodiments of the present invention.
