[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] Reference below Figure 1-Figure 3 The air outlet structure 1 of the vehicle air conditioner according to the embodiment of the present utility model is described. The air outlet structure 1 of the vehicle air conditioner is a component of the vehicle air conditioner.

[0029] like Figure 1-Figure 3 As shown, the air outlet structure 1 of a vehicle air conditioner according to an embodiment of the present invention includes a housing 10 and a damper 20. The housing 10 primarily protects the internal components and enhances the integrity of the air outlet structure 1, while the damper 20 primarily adjusts the direction and flow of air from the vehicle air conditioner, ensuring air circulation and temperature control within the vehicle.

[0030] like Figure 1-Figure 3 As shown, the damper 20 includes a damper body 204 and a damper soft adhesive 205. The damper body 204 is the main part of the damper 20, and the damper soft adhesive 205 is a sealing structure on the damper 20. The inner side of the housing 10 is provided with an air outlet 102, and the inner wall of the housing 10 is provided with a first fastening portion 100. The damper body 204 is rotatably disposed within the housing 10, and the damper soft adhesive 205 is connected to the damper body 204. The damper soft adhesive 205 is provided with a second fastening portion 200. When the damper body 204 closes the air outlet 102, the second fastening portion 200 is fastened to the windward side of the first fastening portion 100 under the action of airflow.

[0031] It should be noted that the first snap-fitting portion 100 and the second snap-fitting portion 200 can both tightly connect two or more components together to ensure that they form a whole in terms of function or structure. The air outlet 102 can adjust the temperature, ensure air circulation and save energy and reduce emissions. The air outlet 102 is provided on the inner side of the shell 10, the inner wall of the shell 10 is provided with the first snap-fitting portion 100, the damper body 204 is rotatably provided in the shell 10, the damper soft glue 205 is connected to the damper body 204, the damper soft glue 205 is provided with the second snap-fitting portion 200, the first snap-fitting portion 100 and the second snap-fitting portion 200 are respectively provided on the inner wall of the shell 10 and the damper soft glue 205, the damper body 204 is provided inside the shell 10 and can rotate. At this time, the space inside the shell 10 can be reasonably utilized to reduce the space occupied by the overall structure, thereby solving the space layout problem of the air outlet structure 1.

[0032] The damper soft rubber 205 can rotate together with the damper body 204. When the damper body 204 closes the air outlet 102, under the action of the airflow, the second fastening part 200 can be fastened and connected with the windward side of the first fastening part 100. That is to say, the damper body 204 can be controlled to close the air outlet 102, and when there is airflow through the vehicle air conditioner, under the action of the airflow, the second fastening part 200 is fastened with the first fastening part 100 and fastened to the windward side of the first fastening part 100. At this time, the vehicle air conditioner airflow can be used for dynamic sealing. The greater the airflow velocity, the greater the fastening force between the second fastening part 200 and the first fastening part 100, the greater the fitting force between the damper 20 and the shell 10, and the better the sealing of the air outlet structure 1, thereby effectively organizing the high-speed airflow of the vehicle air conditioner to pass through and solving the howling problem of the air outlet structure 1.

[0033] In addition, the damper soft rubber 205 is set to a soft rubber structural part, and the hardness of the soft rubber structural part is relatively low. At this time, the structure of the damper soft rubber 205 is simple and easy to deform. The damper soft rubber 205 is more in line with actual working conditions. When high-speed airflow passes through, the damper soft rubber 205 can be deformed along the direction of the airflow, and the second buckling part 200 is buckled on the windward side of the first buckling part 100. At this time, the soft rubber structural part can better fit with the shell 10, and the air outlet structure 1 is reliably sealed in the closed state. The greater the airflow velocity, the greater the fitting force with the shell 10, thereby achieving better dynamic sealing and solving the howling problem of the air outlet structure 1.

[0034] Therefore, an air outlet 102 is provided on the inner side of the shell 10. When the air outlet 102 is closed by the damper main body 204, the second snap-fitting part 200 is snap-fitted and connected with the windward side of the first snap-fitting part 100 under the action of the airflow. At this time, the overall structure of the air outlet structure 1 is simple and the cost is low. In addition, the damper 20 and the shell 10 are redesigned, and the vehicle air-conditioning airflow is cleverly used for dynamic sealing. The greater the airflow velocity, the better the sealing, thereby effectively preventing the high-speed airflow of the vehicle air-conditioning from passing through, and solving the howling problem of the air outlet structure 1.

[0035] Specifically, if Figure 3 As shown, the first locking portion 100 is provided with a first mating plane 101 inclined toward the windward side, and the second locking portion 200 is provided with a second mating plane 201. Under the action of airflow, the second mating plane 201 is attached to the windward side of the first mating plane 101. The first mating plane 101 and the second mating plane 201 can both play the role of fixed connection, force transmission and movement. The first buckling part 100 is provided with a first mating plane 101 inclined toward the windward side, and the second buckling part 200 is provided with a second mating plane 201. Under the action of the airflow, the second mating plane 201 is attached to the windward side of the first mating plane 101. The first mating plane 101 and the second mating plane 201 are respectively arranged on the windward side of the first buckling part 100 and the second buckling part 200, and the first mating plane 101 and the second mating plane 201 are both inclined. When airflow passes through the vehicle air conditioner, under the action of the airflow, the second mating plane 201 is attached to the first mating plane 101, so that the second buckling part 200 can be buckled to the windward side of the first buckling part 100.

[0036] Moreover, if Figure 3 As shown, the first mating plane 101 and the second mating plane 201 are both constructed as planes. At this time, the matching accuracy of the first mating plane 101 and the second mating plane 201 can be improved. Under the action of the airflow, the second snap-fitting part 200 can be better snapped to the windward side of the first snap-fitting part 100, thereby achieving better dynamic sealing and solving the howling problem of the air outlet structure 1.

[0037] Among them, such as Figure 3As shown, the surface area of ​​the first mating plane 101 is s1, the contact area of ​​the second mating plane 201 when it is in contact with the first mating plane 101 is s2, and the relationship between s1 and s2 is: 0.5s1≤s2≤s1. It should be noted that the contact area s2 when the second mating plane 201 and the first mating plane 101 are in contact needs to meet a certain range. Specifically, the contact area s2 when the second mating plane 201 and the first mating plane 101 are in contact cannot be too small, that is, less than 0.5s1. In this way, the contact area when the second mating plane 201 and the first mating plane 101 are in contact is too small, which is not conducive to the second buckling part 200 being buckled on the windward side of the first buckling part 100. At this time, it will affect the dynamic sealing of the air outlet structure 1 and cause a howling problem. At the same time, the contact area s2 when the second mating plane 201 and the first mating plane 101 are in contact cannot be too large, that is, greater than s1. On the premise that the second buckling part 200 can be buckled on the windward side of the first buckling part 100, the maximum contact area s2 when the second mating plane 201 and the first mating plane 101 are in contact is s1, and there is no situation where the contact area s2 is greater than s1 when the second mating plane 201 and the first mating plane 101 are in contact.

[0038] Of course, if Figure 1 As shown, the second fastening portion 200 is further provided with a guide surface 202. When the second mating plane 201 is in contact with the first mating plane 101, the guide surface 202 is connected to the windward side of the second mating plane 201, and the guide surface 202 is tilted toward the windward side. The guide surface 202 mainly provides directional guidance and positioning. The second fastening portion 200 is provided with a guide surface 202. When the second mating plane 201 is in contact with the first mating plane 101, the guide surface 202 is connected to the windward side of the second mating plane 201, and the guide surface 202 is tilted toward the windward side. When the second mating plane 201 is in contact with the first mating plane 101, the guide surface 202 is connected to the windward side of the second mating plane 201, and the guide surface 202 is arranged in an inclined structure.

[0039] Furthermore, if Figure 3As shown, the damper soft rubber 205 is further provided with a weakening portion 203 . When the second buckling portion 200 is buckled onto the windward side of the first buckling portion 100 , the weakening portion 203 is located on the leeward side of the damper soft rubber 205 . The weakening portion 203 can adjust the direction and flow of the wind flow, thereby ensuring the stability and safety of the air outlet structure 1. The damper soft glue 205 is provided with a weakening portion 203. The weakening portion 203 is easy to deform when the air flow passes through. When a high-speed air flow passes through, the damper soft glue 205 deforms along the direction of the air flow. The second buckling portion 200 is buckled with the windward side of the first buckling portion 100. When the second buckling portion 200 is buckled with the windward side of the first buckling portion 100, the weakening portion 203 is located on the leeward side of the damper soft glue 205. When the second buckling portion 200 is buckled with the windward side of the first buckling portion 100, that is, when the damper soft glue 205 is attached to the shell 10, the weakening portion 203 is located on the leeward side of the damper soft glue 205.

[0040] In addition, Figure 3 As shown, the weakening portion 203 is constructed as a weakening groove. By constructing the weakening portion 203 as a weakening groove structure, the force at the weakening groove is relatively small. In this way, when airflow passes through, the damper soft rubber 205 can better deform in the direction of the weakening groove. Since when the second fastening portion 200 is fastened to the windward side of the first fastening portion 100, the weakening portion 203 is located on the leeward side of the damper soft rubber 205. This allows the second fastening portion 200 to be better fastened to the windward side of the first fastening portion 100, making the damper soft rubber 205 more closely fitted to the housing 10, achieving better dynamic sealing, and thus solving the whistling problem of the air outlet structure 1.

[0041] In addition, the air outlet structure 1 of the vehicle air conditioner further includes a driving member that cooperates with the damper body 204 to selectively close the air outlet 102. Specifically, when the air outlet needs to be opened, the driving member drives the damper body 204 to open the air outlet 102, allowing air to flow through the air outlet normally. When the air outlet needs to be closed, the driving member drives the damper body 204 to close the air outlet 102. Under the influence of the airflow, the second fastening portion 200 fastens and connects with the windward side of the first fastening portion 100, thereby providing a dynamic seal and effectively preventing the high-speed airflow of the vehicle air conditioner from passing through, thereby resolving the whistling problem of the air outlet structure.
