[0025] The air-conditioning air outlet structure of the present invention is suitable for various vehicle-mounted air-conditioning air outlets, and mainly comprises a shell and an air inlet regulating device.

[0026] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an air outlet structure of an air conditioner of the present invention, including a shell 1 forming an air duct, a diverter structure 2 formed in the shell 1, and the diverter structure 2 is located in the air duct at the front end of the shell 1, dividing the air duct formed inside the front end of the shell 1 into an upper air duct and a lower air duct. The rear end of the shell 1 is connected to the air conditioning device 6, and the rear end of the shell 1 is a cylindrical shell, forming an air inlet cavity, and the air inlet cavity formed at the rear end of the shell 1 is connected to the upper air duct and the lower air duct formed at the front end of the shell 1. The connection between the rear end of the shell 1 and the front end of the shell 1, that is, the side of the diverter structure 2 close to the air inlet cavity is also provided with a wind direction adjustment device 3, and a damper 4 is provided at the rear end of the shell 1 near the air inlet of the air conditioning device 6.

[0027] Among them, the cross-section of the diversion structure 2 is a shuttle-shaped structure, an upper air duct is formed between the upper surface of the diversion structure 2 and the inner wall of the upper part of the shell 1, and a lower air duct is formed between the lower surface of the diversion structure 2 and the inner wall of the lower part of the shell 1. The final air outlet direction of the upper air duct is downward, and the final air outlet direction of the lower air duct is upward. The wind direction regulator controls the air volume of the air duct with the upward air outlet direction and the air volume of the air duct with the downward air outlet direction of the air outlet structure by adjusting the air volume entering the upper air duct and the lower air duct, thereby adjusting the air outlet direction.

[0028] The working principle of this embodiment is as follows: after the air blown out by the air conditioner enters the air inlet cavity, the area of ​​the air inlet passage is changed by the swing of the damper 4, thereby changing the air volume of the entire air outlet. Then, under the adjustment of the wind direction adjuster 3, the air enters the upper air duct and / or the lower air duct, and then blows out. The wind direction adjuster 3 can adjust the air volume ratio entering the upper air duct and the lower air duct.

[0029] like Figure 2 and Figure 3As shown, in one embodiment, the wind direction regulator 3 is a rotatable sheet structure, which is rotatably arranged in the air duct formed inside the shell 1 through a rotating shaft, and is located near the inlet of the upper air duct and the lower air duct. The rotating shaft of the wind direction regulator 3 is perpendicular to the direction of the wind flowing forward, and the end of the wind direction regulator 3 cooperates with the inner wall of the inlet of the upper and lower air ducts, and adopts a soft material that is secondary injection molded with the body. When the wind direction regulator 3 swings, it can block the inlet of the upper air duct or the inlet of the lower air duct to control the air intake of the upper air duct and the air intake of the lower air duct.

[0030] like Figure 3 As shown, the damper 4 is a sheet-like structure that can rotate around a central axis, and is arranged at the rear end of the housing 1 near the air inlet of the air conditioner 6. The rotating shaft of the damper 4 is perpendicular to the direction in which the wind flows forward. The two ends of the damper 4 cooperate with the inner wall of the air duct, and a soft material is used for secondary injection molding with the body. When the damper 4 swings, it can partially or completely block the air duct to control the total air volume of the outlet and the opening or closing of the outlet.

[0031] In one embodiment, if Figure 2 As shown, the rotating shafts of the wind direction regulator 3 and the damper 4 are connected to the external gear mechanism through gears, wherein the rotating shaft of the wind direction regulator 3 is meshed with the external first gear 7 through the third gear, and the rotation of the third gear is driven by the external first gear 7, thereby driving the wind direction regulator 3 to swing up and down at the entrance of the upper air duct and the lower air duct with its own axis as the center, thereby blocking the upper air duct or the lower air duct; the rotating shaft of the damper 4 is meshed with the external second gear 8 through the fourth gear, and the rotation of the fourth gear is driven by the external second gear 8, thereby driving the damper 4 to swing in the air inlet cavity with its own axis as the center, and by blocking the air inlet cavity, the air intake of the air inlet cavity is controlled, thereby controlling the air intake volume entering the upper air duct or the lower air duct; in this embodiment, the first gear 7 and the second gear 8 are double gear structures, and are respectively half gears, which independently control the swing of the wind direction regulator 3 and the damper 4, and the first gear 7 and the second gear 8 are respectively connected to the shaft of the motor 5, and swing under the drive of the shaft of the motor 5. In this embodiment, the wind direction regulator 3 and the damper 4 are not linked. In other embodiments, the wind direction regulator 3 and the damper 4 can be controlled separately by different motors, that is, when the wind direction regulator 3 swings up and down, the damper 4 can remain in the open state or swing; when the damper 4 swings, the state of the wind direction regulator can remain unchanged or swing up and down.

[0032] like Figure 4As shown, when the wind direction adjuster 3 of this embodiment swings, different wind outlet effects are achieved by blocking the upper and lower wind ducts. Among them, Figure a is a schematic diagram of the wind direction adjuster 3 blocking the lower wind duct inlet and only retaining the upper wind duct outlet. At this time, the wind direction of this wind outlet structure is downward; Figure b is a schematic diagram of the wind direction adjuster 3 blocking the upper wind duct inlet and only retaining the lower wind duct inlet. At this time, the wind direction of this wind outlet structure is upward; Figure c is a schematic diagram of the wind direction adjuster 3 not blocking the upper and lower wind duct inlets, and the upper and lower wind ducts are simultaneously discharged. At this time, the wind direction of this wind outlet structure is horizontal; Figure d is a schematic diagram of the damper 4 blocking the wind duct after swinging, and the air outlet of this wind outlet structure is in a closed state.

[0033] In one embodiment, the rotating shafts of the wind direction regulator 3 and the damper 4 can also be connected to the actuator through a rotating wheel respectively, and the actuator drives the rotating wheel to rotate, thereby driving the wind direction regulator 3 and the damper 4 to swing respectively, and the actuator can be a dial wheel.

[0034] In one embodiment, at least one upper blade is provided at the air duct outlet as a horizontal wind direction control device. Multiple blades are vertically arranged and connected by synchronous connecting rods. They can swing left and right at the air outlet through a rotating shaft to achieve left and right swing control of the outlet wind direction.

[0035] The air outlet structure of an air conditioner of the present invention has a simple structure and occupies a small space. It can conveniently adjust the air outlet direction of the air conditioner up and down, as well as the air outlet direction left and right. Further, the wind direction can be freely adjusted by electric control.

[0036] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
