Description

Technical Field

[0001] This invention relates to the field of vehicle air conditioning vents, specifically to an air conditioning vent assembly and a vehicle. Background Technology

[0002] Natural winds are generally gusty, sometimes strong and sometimes weak. When a strong gust of wind blows, the heat or sweat on the body is "blown away" by the wind, making you feel cool. This happens repeatedly, with gusts of wind blowing gently, making you feel cool continuously.

[0003] Most car air conditioning vents on the market are currently characterized by a large horizontal length and a small vertical height. Each vent contains a set of left-right airflow adjustment blades to regulate the lateral airflow. These blades are parallel and rotate synchronously, resulting in a large, parallel airflow. When this large, concentrated airflow blows onto a specific area of ​​the body for an extended period, it rapidly dries sweat from the skin. When there is virtually no sweat evaporating, the skin becomes dry, and the person no longer feels cool, and may even feel uncomfortable. Therefore, this current large, parallel airflow pattern of air conditioning vents negatively impacts passenger comfort. Even when the vents switch to a left-right swing mode, it only provides a brief period of airless airflow to the upper part of the passenger area during a single swing cycle, failing to improve comfort. Therefore, research is needed to develop methods to make the airflow from air conditioning vents more comfortable. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an air conditioning outlet assembly with a simulated natural wind outlet mode, making the user's airflow more comfortable.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example, see attached document Figure 1-10 An air conditioning vent assembly, comprising: The housing 100 includes an outer shell 110 and an inner shell 120. The inner shell 120 is disposed in the outer shell 110 and separates the air passage inside the outer shell 110. The air passage includes an air inlet 130, an air inlet channel 140, a first air outlet channel 150, a second air outlet channel 160, and an air outlet 170. The blade assembly 200, located within the housing 100 near the air outlet 170, includes at least two first blades 210, a first connecting rod 220, at least two second blades 230, and a second connecting rod 240. The first connecting rod 220 is connected to each of the first blades 210, and each of the first blades 210 rotates synchronously via the first connecting rod 220. The second connecting rod 240 is connected to each of the second blades 230, and each of the second blades 230 rotates synchronously via the second connecting rod 240. The first blades 210 and the second blades 230 are arranged adjacently and alternately, and their axes are in the same plane. In this embodiment, there are three first blades 210 and three second blades 230. The transmission mechanism 300 includes a transmission assembly, a first crank 340, and a second crank 350. In this embodiment, the transmission assembly includes a first rotating member 310, a second rotating member 320, and a transmission gear 330. The first rotating member 310 is provided with a first track portion 311. The second rotating member 320 is connected to the first rotating member 310 through the transmission gear 330 and rotates synchronously. The second rotating member 320 is provided with a second track portion 321. The first crank 340 includes a first linkage portion 341 and a first rotating shaft portion 342. 1. It is configured to move along the first track section 311, and the first rotating shaft section 342 is circumferentially fixedly connected to a first blade 210; the second crank 350 includes a second linkage section 351 and a second rotating shaft section 352, the second linkage section 351 is configured to move along the second track section 321, and the second rotating shaft section 352 is circumferentially fixedly connected to a second blade 230; in this embodiment, both the first linkage section 341 and the second linkage section 351 are preferably linkage column structures, and both the first track section 311 and the second track section 321 are preferably track groove structures; The drive mechanism 400 is configured to drive the transmission component to move and to move the transmission component sequentially to a first position, a second position, a third position, and a fourth position. A synchronous sweeping interval is formed between the first position and the second position, a transition interval is formed between the second position and the third position, and a natural wind interval is formed between the third position and the fourth position. In this embodiment, the drive mechanism 400 can drive the first rotating member 310 to rotate, and the first rotating member 310 drives the second rotating member 320 to rotate in the same direction through the transmission gear 330. The angular positions of the first blade 210 and the second blade 230 are determined by the trajectory shapes of the first trajectory section 311 and the second trajectory section 321, respectively. The trajectory shapes of the first trajectory section 311 and the second trajectory section 321 are configured such that when the transmission assembly moves between the first position and the second position, the first blade 210 and the second blade 230 rotate synchronously and in the same direction, and when the transmission assembly moves between the third position and the fourth position, the first blade 210 and the second blade 230 rotate synchronously but in opposite directions.

[0026] The working principle of the air conditioner outlet assembly in this embodiment: The air conditioning vent assembly has two air outlet modes: synchronous swing mode and natural wind mode. When the drive mechanism 400 drives the transmission assembly to move in the synchronous sweeping zone formed between the first and second positions, the first blade 210 and the second blade 230 rotate synchronously and in the same direction. Since the blades are parallel, the outlet 170 blows out a parallel and uniform airflow. As the blades swing back and forth, a synchronous sweeping mode is formed, which is equivalent to the existing air outlet 170's airflow mode. When the drive mechanism 400 drives the transmission assembly to move in the natural wind zone formed between the third and fourth positions, the first blade 210 and the second blade 230 rotate synchronously but in opposite directions. Since the first blade 210 and the second blade 230 are staggered, as the blades swing back and forth, the airflow through each air outlet zone formed by two adjacent blades will continuously change, forming a natural wind mode, thereby simulating the effect of natural wind. The airflow change mode of each air outlet zone can be customized according to the needs of the user or OEM. The requirements can be met by designing the trajectory shape of the first trajectory section 311 and the second trajectory section 321.

[0027] This embodiment provides a specific solution: When the transmission assembly moves to the first position, both the first blade 210 and the second blade 230 are in the first extreme position of airflow to the left, such as... Figure 5 As shown; when the transmission assembly moves to the second position, both the first blade 210 and the second blade 230 are in the second extreme position of rightward airflow, as... Figure 7 As shown; when the transmission component moves in the synchronous sweeping interval formed between the first position and the second position, the air outlet assembly of the air conditioner is in synchronous sweeping mode and the air outlet direction changes back and forth between the left and right. When the transmission assembly moves to the third position, the first blade 210 and the second blade 230 are respectively at the fourth limit position of right-directed airflow and the third limit position of left-directed airflow, as shown below. Figure 8 As shown; when the transmission assembly moves to the fourth position, the first blade 210 and the second blade 230 are respectively at the third extreme position of airflow to the left and the fourth extreme position of airflow to the right, as shown. Figure 10As shown; when the transmission component moves within the natural wind zone formed between the third and fourth positions, the air outlet assembly operates in natural wind mode. The preset target area is subjected to airflow with varying air volume. In natural wind mode, the upper limit of air volume is equivalent to that in synchronous sweep mode, while the lower limit depends on the relative position of the third and fourth limit positions of the blades, i.e., the angle between them. The larger the angle between the third and fourth limit positions, the smaller the lower limit of air volume, and vice versa. Therefore, by reasonably setting the relative angle between the third and fourth limit positions, the range of air volume variation in natural wind mode can be adjusted, thereby simulating the fluctuations in wind strength in the natural environment and providing users with a more comfortable air supply experience.

[0028] Furthermore, when the transmission assembly moves in the transition zone between the second and third positions, the first blade 210 and the second blade 230 can rotate simultaneously, or only the first blade 210 can rotate, or only the second blade 230 can rotate.

[0029] In this embodiment, the air conditioning vent assembly can simulate the effect of natural wind in natural wind mode. Users can feel the airflow blowing with varying air volume, which can improve the user's comfort when exposed to air.

[0030] Besides the embodiment described herein, there are many other specific implementations of the transmission assembly structure. Three of them are described below:

[0031] One specific implementation method, such as Figure 11 As shown, the transmission assembly includes a translation member 361, a transmission rod 362, and a transmission disk 363; the drive mechanism 400 drives the transmission disk 363 to rotate, and while the transmission disk 363 rotates, it drives the translation member 361 to move through the transmission rod 362. The translation member 361 is configured to only be able to translate on the housing 100, and the translation member 361 is provided with a first track portion 311 and a second track portion 321.

[0032] In the second specific implementation, the transmission component includes a third rotating member, a first track portion is provided on the first surface of the third rotating member, and a second track portion is provided on the second surface, with the first surface and the second surface being in a front-to-back relationship.

[0033] In the third specific implementation, the transmission assembly includes a fourth rotating member, and a first track portion and a second track portion are provided on the end face of the fourth rotating member. The first track portion and the second track portion are in an inner ring and an outer ring position relative to the axis of the fourth rotating member.
