[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1A foldable and flexible air outlet for air conditioning comprises a base 10, a hose 11 and an air guide tube 12. The base 10 is movably mounted on a car, and one end of the base 10 is connected to the air outlet of the car air conditioner. One end of the hose 11 is connected to the air outlet of the base 10 through a fixed steel ring, and the other end is connected to the air inlet of the air guide tube 12. The hose 11 is used to guide the airflow from the base 10 into the air guide tube 12. The air outlet also comprises a damper 2 and a rotating mechanism 3. The damper 2 is installed in the air guide tube 12 along the radial direction of the air guide tube 12, and the number of dampers 2 is not less than three. The plurality of dampers 2 are distributed in a circular array on the air guide tube 12 with the axis of the air guide tube 12 as the center line, and are used to adjust the wind direction angle and air volume between the damper 2 and the air guide tube 12. The rotating mechanism 3 rotates along the axial direction. It is dynamically installed in the air guide tube 12 and is coaxial with the air guide tube 12, and is slidably abutted against the air doors 2, and is used to synchronously adjust several air doors 2 to rotate at equal angles along the radial direction of the air guide tube 12; a plurality of air doors 2 are arranged in the air guide tube 12, and the plurality of air doors 2 are distributed in a circular array with the axis of the air guide tube 12 as the center line and can rotate along the radial direction of the air guide tube 12, so that when the air door 2 is rotated to open, the wind direction of the hose 11 flowing into the air guide tube 12 is deflected under the action of the air door 2 and the wind direction angle and wind volume between the air guide tube 12 and each air door 2 are adjusted, and then the plurality of air doors 2 are synchronously adjusted at equal angles through the rotating mechanism 3, so that the wind direction angle and wind volume through the air guide tube 12 and each air door 2 are consistent and a uniform spiral wind is formed, so as to achieve a simple, convenient, efficient and uniform air outlet effect.

[0033] In order to further improve the uniformity of the air outlet of the air conditioner, specifically, the air door 2 includes an air guide plate 21 and a linkage assembly 22. The air guide plate 21 is installed in the air guide tube 12 along the radial rotation of the air guide tube 12. A first mounting hole adapted to the air guide plate 21 is provided in the air guide tube 12. During the rotation of the air guide plate 21, a gap between the air guide plate 21 and the air guide tube 12 forms an air flow channel. The linkage assembly 22 is arranged on the air guide plate 21 and slidably abuts against the rotating mechanism 3, and is used to cooperate with the rotating mechanism 3 to drive the air guide plate 21 to rotate, such as Figure 2 As shown; the rotating mechanism 3 interacts synchronously with the linkage components 22 on the multiple air doors 2 and drives the multiple air guide plates 21 to rotate at equal angles with the radial direction of the air guide tube 12 as the axis, so that the angle and opening and closing gap between each air guide plate 21 and the air guide tube 12 are consistent, thereby avoiding the situation where the wind direction and air volume between each air guide plate 21 and the air guide tube 12 are inconsistent, which affects the uniformity of the air outlet of the air conditioner.

[0034] In order to further improve the air outlet uniformity of the air conditioner, specifically, the linkage assembly 22 includes a first baffle 221 and a second baffle 222. The first baffle 221 is fixedly installed on the side of the air guide plate 21 away from the base 10 and is slidably abutted against the rotating mechanism 3. The second baffle 222 is spaced relative to the first baffle 221 and fixedly installed on the air guide plate 21. A guide groove a is formed between the first baffle 221 and the second baffle 222, which is slidably abutted against the rotating mechanism 3. The guide groove a between the first baffle 221 and the second baffle 222 is used to slide against the rotating mechanism 3, so that the rotating mechanism 3 always abuts against the first baffle 221 and the second baffle 222 when rotating clockwise or counterclockwise, and accurately limits the air guide plate 21, so as to avoid the air guide plate 21 from falling off from the rotating mechanism 3 during rotation, thereby affecting the air outlet uniformity between each air guide plate 21 and the air guide tube 12.

[0035] In order to further improve the air outlet uniformity of the air conditioner, specifically, the center line of the guide groove a and the rotation axis of the air guide plate 21 are in the same plane and perpendicular to each other, so that the rotating mechanism 3 rotates clockwise or counterclockwise by the same angle, and the rotating mechanism 3 drives the air guide plate 21 to rotate clockwise or counterclockwise through the first baffle 221 and the second baffle 222 to have a consistent deflection angle, and the acting force between the rotating mechanism 3 and the first baffle 221 and the second baffle 222 is consistent, thereby avoiding the situation where the first baffle 221, the second baffle 222 and the air guide plate 21 are subjected to inconsistent forces, resulting in deformation or damage, thereby affecting the air outlet uniformity of the air conditioner.

[0036] In order to further improve the uniformity of the air outlet of the air conditioner, specifically, the rotating mechanism 3 includes a turntable 31, a knob 32 and a driving assembly 33. The turntable 31 is axially rotatably installed in the air guide tube 12 and is coaxial with the air guide tube 12. The knob 32 is movably installed on the side of the turntable 31 away from the base 10. The outer wall of the knob 32 is provided with an anti-slip groove. The driving assembly 33 is arranged on the turntable 31 and extends into the guide groove a. The driving assembly 33 drives the air guide plate 21 to rotate radially along the air guide tube 12 through the first baffle plate 221 and the second baffle plate 222. In this embodiment, the turntable 31 and the knob 32 are used to drive the driving assembly 33 to rotate. A servo motor and a gear can also be used to drive the driving assembly 33 to rotate. Figure 3 As shown; by rotating the knob 32, the knob 32 drives the driving assembly 33 through the turntable 31 to synchronously interact with the first baffle 221 and the second baffle 222 on the multiple air guide plates 21 and adjust the gap between the air guide plate 21 and the air guide tube 12 at equal angles, thereby achieving a uniform air outlet effect.

[0037] In order to further improve the air outlet uniformity of the air conditioner, specifically, the driving component 33 includes a vertical plate 331 and a screw 332. The vertical plate 331 is fixedly mounted on the turntable 31, and the screw 332 is movably mounted on the vertical plate 331 along the radial direction of the air guide tube 12 and slides against the first baffle 221 and the second baffle 222. The number of screws 332 is equal to the number of air guide plates 21, and the screws 332 are distributed in a circular array with the axis of the air guide tube 12 as the center line; the driving component 33 adopts the vertical plate 331 and the screw 332 in combination, so that the cylindrical surface of the screw 332 is always in arc-shaped gradual line contact with the first baffle 221 and the second baffle 222 when relative motion occurs, thereby reducing the driving resistance of the driving component 33, and avoiding the situation where the driving component 33 and the first baffle 221 and the second baffle 222 are severely worn and affect the air outlet uniformity of the air conditioner.

[0038] In order to further improve the uniformity of the air outlet of the air conditioner, specifically, the distance between the air guide plate 21 and the turntable 31 is smaller than the maximum distance between the edge of the air guide plate 21 and its rotation axis, that is, when the air shield 21 rotates to the maximum angle β, β is less than ninety degrees, the side of the air guide plate 21 away from the base 10 is against the turntable 31, and when the plane where the air guide plate 21 is located is perpendicular to the axis of the air guide cylinder 12, the distance D between the screw 332 and the air guide plate 21 is the smallest, and the minimum distances between the first baffle 221 and the second baffle 222 and the air guide plate 21 are not less than The minimum spacing between the first baffle 221, the second baffle 222 and the air guide plate 21 is not less than D / cosβ, that is, when the wind shield 21 is rotated clockwise or counterclockwise to the maximum angle β, the first baffle 221 and the second baffle 222 are both against the screw 332, thereby preventing the screw 332 from falling off from the first baffle 221 and the second baffle 222, causing the air guide plate 21 to adaptively deflect and affect the consistency of the angles between the multiple air guide plates 21 and the air guide tube 12, thereby improving the air outlet uniformity of the air conditioner.

[0039] In the above embodiment of the present technical solution, the linkage assembly 22 adopts the first baffle 221 and the second baffle 222 to cooperate with the vertical plate 331 and the screw 332 on the driving assembly 33 to synchronously drive the air guide plate 21 to rotate at the same angle. The hinge seat p and the connecting rod q can also be used to cooperate with the vertical plate 331 and the screw 332 on the driving assembly 33 to synchronously drive the air guide plate 21 to rotate at the same angle. Figure 4 As shown, it is sufficient to ensure that the wind guide plate 21 is adjusted to rotate radially along the wind guide tube 12 synchronously and at equal angles.

[0040] In order to further improve the air outlet uniformity of the air conditioner, specifically, a telescopic mechanism 4 is further included, one end of which is fixedly connected to the base 10, and the other end is movably connected to the knob 32, which is used to adjust the distance and angle between the knob 32 and the base 10, such as Figure 5 As shown; the distance and angle between the knob 32 and the base 10 are adjusted and positioned through the telescopic mechanism 4. Since the knob 32 is movably installed on the turntable 31, the turntable 31 is axially rotatably installed in the air guide tube 12, thereby limiting the distance and angle between the base 10 and the air guide tube 12, thereby avoiding the situation in which the hose 11 is excessively twisted and deformed during the telescopic adjustment process of the base 10 and the air guide tube 12, thereby affecting the uniformity of the air outlet from the gap between the air guide plate 21 and the air guide tube 12.

[0041] In order to further improve the uniformity of the air outlet of the air conditioner, specifically, the telescopic mechanism 4 includes a positioning cylinder 41, a first sleeve 42, a spring 43 and a rotating assembly 44. The positioning cylinder 41 is fixedly installed on the base 10, the first sleeve 42 is sleeved on the outer wall of the positioning cylinder 41, a through hole m is provided on the first sleeve 42, a block n extending into the through hole m is fixedly installed on the positioning cylinder 41, a positioning groove is provided on the inner wall of the first sleeve 42, a positioning block extending into the positioning groove is provided on the outer wall of the positioning cylinder 41, one end of the spring 43 is movably connected to the positioning cylinder 41, and the other end is movably connected to the rotating assembly 44, a second mounting hole adapted to the spring 43 is provided inside the positioning cylinder 41, and the rotating assembly 44 is arranged on the side of the first sleeve 42 away from the base 10 and is movably connected to the knob 32; through The spacing between the air guide tube 12 and the base 10 is adjusted by telescopic pulling, and the angle between the positioning tube 41 and the first sleeve 42 is limited by the sliding cooperation of the positioning block on the positioning tube 41 and the positioning groove on the first sleeve 42, and the adjustment spacing between the rotating component 44, the knob 32 and the air guide tube 12 and the base 10 is limited by the sliding of the clamping block n on the positioning tube 41 and the first sleeve 42. When the clamping block n on the positioning tube 41 is engaged with the through hole m on the first sleeve 42, the adjustment spacing between the air guide tube 12 and the base 10 is maximized, thereby avoiding the positioning tube 41 and the first sleeve 42 from falling off or rotating during the adjustment of the air outlet of the air conditioner, causing the hose 11 to be excessively twisted and deformed under the gravity of the air guide tube 12 itself, thereby affecting the uniformity of air outlet from the gap between the air guide plate 21 and the air guide tube 12.

[0042] In order to further improve the uniformity of the air outlet of the air conditioner, specifically, the block n includes an elastic portion x, a supporting surface y and a guide surface z. The elastic portion x is provided with a supporting surface y which is axially perpendicular to the positioning cylinder 41. The supporting surface y is used to limit the axial position of the first sleeve 42 and the positioning cylinder 41. The end of the elastic portion x away from the base 10 is provided with an inclined transition guide surface z. The rotating component 44 includes a ball rod 441 and a limiting cylinder 442. The ball rod 441 is sleeved on the end of the first sleeve 42 away from the base 10 and is movably connected to the spring 43. A third mounting hole adapted to the spring 43 is provided in the ball rod 441. A groove adapted to the first sleeve 42 is provided in the ball rod 441. The limiting cylinder 442 is fixedly installed on the inner side of the knob 32 and sleeved on the outer wall of the ball rod 441. Figure 6 and Figure 7 As shown; when the block n is located on the inner side of the first sleeve 42, the elastic portion x of the block n on the positioning tube 41 elastically abuts against the first sleeve 42 and defines the positions of the positioning tube 41 and the first sleeve 42. When the block n is engaged with the through hole m on the first sleeve 42, the elastic portion x of the block n on the positioning tube 41 drives the abutting surface y to abut against the inner wall of the through hole m and defines the positions of the positioning tube 41 and the first sleeve 42. When it is necessary to compress the positioning tube 41 and the first sleeve 42, the elastic portion x on the block n drives the guide surface z to cooperate with the gradual bending of the first sleeve 42 to achieve rapid compression, thereby achieving precise extension and positioning between the air guide tube 12 and the base 10, and then the angle of the air guide tube 12 is limited by the ball rod 441 on the rotating component 44 in cooperation with the limiting tube 442, so as to achieve a simple, convenient, high-precision, multi-stage regulator and uniform air outlet effect.

[0043] Working principle of this technical solution:

[0044] By rotating the knob 32, the knob 32 simultaneously drives the plurality of screws 332 to interact with the first baffle 221 and the second baffle 222 on the air guide plate 21 through the turntable 31 and the vertical plate 331, and synchronously adjusts the angle and opening degree between the plurality of air guide plates 21 and the air guide cylinder 12 at equal angles, so that the wind direction of the hose 11 flowing into the air guide cylinder 12 is guided by the plurality of air guide plates 21 to achieve the effect of spiral uniform air discharge, and then the distance between the air guide cylinder 12 and the base 10 is adjusted by telescopic adjustment, and the air guide cylinder 12 drives the first sleeve 42 and the positioning cylinder 41 through the turntable 31 and the knob 32. Retract and extend, and at the same time, the block n and the through hole m on the first sleeve 42 and the positioning cylinder 41 and the positioning groove and the positioning block respectively limit the axial adjustment spacing and radial angle of the ball rod 441 and support the air guide tube 12 to prevent the hose 11 from excessively twisting and deforming under the gravity of the air guide tube 12 itself and affecting the uniformity of the air outlet between the air guide plate 21 and the air guide tube 12. Finally, by rotating the air guide tube 12, the air guide tube 12 drives the limit tube 442 and the ball rod 441 to rotate relative to each other through the turntable 31 and the knob 32, thereby performing multi-stage adjustment and limiting of the wind direction of the air guide tube 12.
