Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] As Figures 1 to 4 shown, an adjustable air outlet assembly for automobiles, construction machinery, and agricultural machinery includes a housing 1, a bright ring 2, a rotating outer shell 3, a rotating inner shell 4, a ball head one 7, a ball head two 8, a bracket cover 10, a light strip 11, a gear 12, a spring cap 15, and a spring 16.

[0034] Specifically, the bright ring 2 is installed above the housing 1. The rotating outer shell 3 is installed inside the housing 1, and the rotating inner shell 4 is installed inside the rotating outer shell 3. The ball head one 7 and the ball head two 8 are installed inside the rotating inner shell 4. An atmosphere light 6 is installed above the ball head one 7 and the ball head two 8, a knob cover 5 is installed above the atmosphere light 6, a rotating shaft 9 is installed in the middle shaft hole of the housing 1, a gear 12 is installed below the rotating shaft 9, and an air damper blade one 13 and an air damper blade two 14 are installed below the gear 12. The air damper blade one 13 and the air damper blade two 14 are installed in the corresponding side holes of the housing 1, and the air damper blade one 13 and the air damper blade two 14 form an air damper assembly.

[0035] The knob cover 5, the atmosphere light 6, the rotating shaft 9, and the gear 12 form a knob link mechanism.

[0036] Specifically, the light strip 11 is inserted into the middle shaft hole of the rotating shaft 9, the bracket cover 10 is installed inside the housing 1, and the support cover 10 is connected to the outer circumference of the rotating shaft 9.

[0037] Specifically, the first ball head 7 and the second ball head 8 form a combined component, which is installed in the middle shaft hole of the rotating inner shell 4 and is located below the rotating inner shell 4. There is ball head soft glue smeared between the first ball head 7 and the second ball head 8, and the ball head soft glue is on the inner sides of the first ball head 7 and the second ball head 8 through two - time injection molding.

[0038] Specifically, the spring cap 15 and the spring 16 form a spring assembly, and the spring assembly is located between the lower side inside the housing 1 and the upper side inside the gear 12. One end of the spring assembly is installed on the round hole of the gear 12, and the other end is installed in the reserved hole on the inner side below the housing 1. The spring assembly can improve the movement texture, effectively reduce noise, and extend the service life.

[0039] Specifically, the rotating outer shell 3, the rotating inner shell 4, the knob cover 5, the atmosphere lamp 6, the first ball head 7, the second ball head 8, the rotating shaft 9, the gear 12, the first air damper blade 13, and the second air damper blade 14 form the air - outlet direction and air - volume adjustment structure of the air conditioner.

[0040] In this embodiment: The rotating outer shell 1 drives the knob link mechanism, thereby driving the gear to rotate. Through the meshing structure, the air damper blade is driven to rotate, so as to open or close the air damper, improve the texture of stepless adjustment of the air outlet, and facilitate assembly at the same time.

[0041] Specifically, an air - outlet foam 17 is arranged on the outer side of the housing 1, and the air - outlet foam 17 is arranged below the outer side of the housing 1.

[0042] In this embodiment: Through the setting of the air - outlet foam 17, it is avoided that abnormal noise and air leakage occur between the air outlet assembled into the interior body and the air duct.

[0043] Specifically, when the first air damper blade 13 and the second air damper blade 14 are opened, their shapes are in a "one" shape. When not in use, they can be hidden inside the housing 1. Through the setting of the air - damper rubber coating, it is avoided that abnormal noise occurs when the air - damper blade touches the housing 1, and at the same time, the sealing performance when the air damper is closed is improved. Using two air - damper blades can more easily adjust the air volume of the air outlet and increase the range of air - volume adjustment of the air outlet.

[0044] Specifically, a first angle - limiting mechanism is arranged between the rotating inner shells 4, and the rotation angle of the rotating inner shell 4 is adapted to the first angle - limiting mechanism. A second angle - limiting mechanism is arranged between the housing 1 and the rotating shaft 9, and the rotation angle of the rotating shaft 9 is adapted to the second angle - limiting mechanism. The two angle - limiting mechanisms can effectively adjust the air direction. A soft rubber pad is arranged below the rotating shaft 9 to improve the movement texture and avoid damage to the air outlet caused by improper operation of the air outlet.

[0045] Specifically, a plurality of self - elastic clamping mechanisms are arranged on the outer side of the housing 1 for assembling with the mating part, and the clamping mechanisms are located on the upper side of the housing 1 and the inner side of the assembly with the mating part.

[0046] When the utility model is specifically used, firstly, the rotation of the outer shell 3 drives the rotation of the inner rotating shell 4, so that the first ball head 7, the second ball head 8 and the rotating shaft 9 rotate, and then drives the gear 12 to rotate. Through the meshing structure, the first air damper blade and the second air damper blade are driven to rotate, so as to open or close the air damper, and improve the texture of stepless adjustment of the air outlet;

[0047] Finally, the rotation of the outer shell 3 drives the rotation of the knob link mechanism, so as to drive the gear 12 to rotate in multiple directions, solve the problem of multi-directional adjustment of the air outlet, improve the practicability and beauty. When the air damper is in the closed state, the first air damper blade 13 and the second air damper blade 14 are hidden inside the outer shell body, and the external atmosphere lamp head provides a light source, so that the light strip installed in the shell body and the atmosphere lamp installed under the knob cover emit light. Compared with the air outlets of traditional construction machinery and agricultural machinery, the internal structure is simplified and the working state can be observed in real time while ensuring the function and strength.
