When the air is blown in a windless manner, the first movable plate is located at the air outlet of the first air outlet channel, and the second movable plate is located at the air outlet of the second air outlet channel. The windless air deflector can convert the normal air flow into windless air flow.

Description

Technical Field

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

[0002] Windless vehicle air conditioning vents are a relatively new concept, and there are currently few patents related to them. "Windless" doesn't mean absolutely no wind; rather, it means that the average wind speed at the windless test location is no greater than 0.3 m / s, so the human body can barely feel the airflow, meaning they cannot feel the air blowing from the vehicle's air conditioning vents.

[0003] There are several important indicators for windless air outlets: air volume Q, wind speed V, and affected area S. These three are related by the formula V=Q / S. When the wind speed V is constant, the larger the affected area S is, the greater the air volume Q will be. The size of the air volume Q directly affects the cooling efficiency of the vehicle's air conditioning vents in windless working mode.

[0004] The structural difference between windless vehicle air conditioning vents and traditional ones is quite simple: the addition of a windless baffle. By switching the position of the baffle, one can switch between windless and normal airflow. However, the presence of the windless baffle in current windless vehicle air conditioning vents either affects or obstructs airflow within the vent, has a negligible effect with a small affected area, or increases the size of the vent, leading to increased space requirements for installation. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a windless air conditioning vent assembly that can add a windless function without affecting the existing vent structure.

[0006] This invention proposes a windless air conditioning vent assembly, comprising a housing, a control mechanism, and a windless air guide plate. The control mechanism can control the movement of the windless air guide plate between a normal air outlet position and a windless air outlet position. The windless air guide plate includes a first movable plate and a second movable plate, each having a plurality of ventilation holes. When the windless air guide plate is in the normal air outlet position, it forms an air channel within the housing together with the housing. The air channel includes a smoothly extending first air outlet channel, a second air outlet channel, and an air inlet channel. The channel wall of the first air outlet channel includes the first movable plate, and the channel wall of the second air outlet channel includes the second movable plate. When the windless air guide plate is in the windless air outlet position, the first movable plate is located at the air outlet of the first air outlet channel, and the second movable plate is located at the air outlet of the second air outlet channel.

[0007] Furthermore, the housing also has cavities that are respectively connected to the first air outlet channel and the second air outlet channel; when the windless air guide plate is in the normal air outlet position, the first movable plate and the second movable plate can respectively cover the two connecting ports of the cavity.

[0008] Furthermore, the housing also includes a partition located between the air outlet of the first air outlet channel and the air outlet of the second air outlet channel.

[0009] Furthermore, the partition has several ventilation holes that communicate with the cavity.

[0010] In a preferred embodiment, the housing includes an outer shell and a middle shell, the middle shell including a groove for placing a windless air guide plate; when the windless air guide plate is in the normal air outlet position, the windless air guide plate is located in the groove.

[0011] Furthermore, the first movable plate and the second movable plate are rotatably connected to the housing via their respective rotating shafts.

[0012] Furthermore, the control mechanism includes a turntable component, an intermediate transmission component, a first crank, and a second crank. The first crank is fixedly connected to the rotation shaft of the first movable plate, and the second crank is fixedly connected to the rotation shaft of the second movable plate. The turntable component is connected to and drives the first crank and the second crank to rotate through the intermediate transmission component. The transmission ratio between the turntable component and the first crank is different from the transmission ratio between the turntable component and the second crank.

[0013] The present invention also proposes a vehicle comprising the windless air conditioning vent assembly described above.

[0014] The beneficial effect of this invention is that the windless air guide plate does not affect the internal structure of the air conditioning outlet assembly. When the windless air guide plate is in the normal air outlet position, it can serve as part of the air outlet channel, guiding the airflow direction without obstructing airflow. When the windless air guide plate is in the windless air outlet position, it can convert normal airflow into windless airflow. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1, refer to Appendix Figure 1-4 A windless air conditioning outlet assembly includes a housing 10, a control mechanism 20, and a windless air guide plate 30. The control mechanism 20 can control the movement of the windless air guide plate 30 between a normal air outlet position and a windless air outlet position. The windless air guide plate 30 includes a first movable plate 31 and a second movable plate 32, each having a plurality of ventilation holes. The first movable plate 31 and the second movable plate 32 are rotatably connected to the housing 10 via their respective rotating shafts.

[0024] When the windless air guide plate 30 is in the normal air outlet position, the windless air guide plate 30 forms an air channel together with the housing 10 inside the housing 10. The air channel includes a smoothly extending first air outlet channel 12, a second air outlet channel 13, and an air inlet channel 11. In this invention, when air flows along the channel wall of the air channel and is not affected by protrusions or indentations on the channel wall that obstruct or affect the airflow, the air channel can be considered to be smoothly extending. The channel wall of the first air outlet channel 12 includes a first movable plate 31, and the channel wall of the second air outlet channel 13 includes a second movable plate 32.

[0025] When the windless air guide plate 30 is in the windless air outlet position, the first movable plate 31 is located at the air outlet of the first air outlet channel 12, and the second movable plate 32 is located at the air outlet of the second air outlet channel 13.

[0026] In this embodiment, the windless air guide plate 30 will not significantly affect the internal structure of the air conditioning outlet assembly. When the windless air guide plate 30 is rotated to the normal air outlet position, it can serve as part of the channel wall of the air outlet channel, guiding the airflow direction without obstructing airflow. When the windless air guide plate 30 is rotated to the windless air outlet position, it can convert the normal airflow into windless airflow. Meanwhile, since the first movable plate 31 and the second movable plate 32 are located at the air outlets of the first air outlet channel 12 and the second air outlet channel 13, respectively, the housing 10 of the air conditioning outlet assembly will not affect the air outlet area when there is no wind.

[0027] Generally, due to individual user differences, different users have different requirements for the vertical airflow direction during normal airflow mode. The vertical airflow direction of the air conditioning vent assembly is adjusted by the airflow ratio between the first airflow channel 12 and the second airflow channel 13. When the airflow mode of the air conditioning vent assembly is switched from normal airflow mode to windless airflow mode, the probability that the vertical airflow direction is exactly at a horizontal angle is the lowest. If the air conditioning vent assembly is electrically adjustable, it can automatically adjust to make the airflow between the first airflow channel 12 and the second airflow channel 13 the same when switching to windless airflow mode, thus ensuring that the windless airflow of both the first airflow channel 12 and the second airflow channel 13 works normally, and that the efficiency of the air conditioning vent assembly reaches its maximum in windless airflow mode. However, if the air conditioning vent assembly is manually adjustable, the user will need to perform an additional operation to adjust the direction of the airflow up and down. Otherwise, the airflow of the first air outlet channel 12 and the second air outlet channel 13 may be unbalanced, which will lead to a decrease in the cooling efficiency of the air conditioning vent assembly in the windless air outlet mode.

[0028] To avoid the reduced efficiency in the windless airflow mode, this embodiment also includes a cavity 14 within the housing 102, which connects to the first airflow channel 12 and the second airflow channel 13. When the windless airflow guide plate 30 is in the normal airflow position, the first movable plate 31 and the second movable plate 32 can respectively cover the two connecting openings of the cavity 14. When the windless airflow guide plate 30 is in the windless airflow position, the presence of the cavity 14 connects the first airflow channel 12 and the second airflow channel 13 and balances the airflow pressure of the first airflow channel 12 and the second airflow channel 13, ultimately maximizing the cooling efficiency in the windless airflow mode. When the windless airflow guide plate 30 is in the normal airflow position, the first movable plate 31 and the second movable plate 32 can respectively cover the two connecting openings of the cavity 14, thereby minimizing the impact of the cavity 14 on the airflow of the first airflow channel 12 and the second airflow channel 13.

[0029] In this embodiment, the housing 10 further includes a partition 15 located between the air outlet of the first air outlet channel 12 and the air outlet of the second air outlet channel 13. The partition 15 has several ventilation holes communicating with the cavity 14. The partition 15 has two functions: first, it can serve as an external decorative panel and block the gap between the pivot of the first movable plate 31 and the pivot of the second movable plate 32; second, since the ventilation holes on it are connected to the cavity 14, when the air conditioning outlet assembly is in a windless air outlet mode, the partition 15 can also serve as an independent air outlet, distinct from the first air outlet channel 12 and the second air outlet channel 13, which is equivalent to expanding the air outlet influence area of ​​the air conditioning outlet assembly. It should be noted that in this embodiment, the ventilation holes on the first movable plate 31, the second movable plate 32, and the partition 15 all have the same function: to convert normal airflow into windless airflow.

[0030] In actual structural design, due to the structural differences between the first air outlet channel 12 and the second air outlet channel 13, the rotation angles of the first movable plate 31 and the second movable plate 32 will differ when the air outlet mode of the air conditioning vent assembly is switched. Therefore, in this embodiment, the control mechanism 20 includes a drive motor 40, a turntable component 21, an intermediate transmission component 22, a first crank 23, and a second crank 24. The first crank 23 is fixedly connected to the rotation shaft of the first movable plate 31, and the second crank 24 is fixedly connected to the rotation shaft of the second movable plate 32. The turntable component 21 is connected to and drives the first crank 23 and the second crank 24 to rotate through the intermediate transmission component 22. The transmission ratio between the turntable component 21 and the first crank 23 is different from the transmission ratio between the turntable component 21 and the second crank 24, so that when the turntable component 21 rotates, the first crank 23 and the second crank 24, which are driven by the intermediate transmission component 22, can each rotate by a preset angle. In this embodiment, the transmission between the various components in the control mechanism 20 can be achieved through various structural forms to realize the basic function. For example, it can be achieved through gear mechanism transmission or crank-connecting rod mechanism transmission. For details, please refer to the existing technology.

[0031] Example 2: A windless air conditioner vent assembly includes a housing 10, a control mechanism 20, and a windless air guide plate 30. The housing 10 includes an outer shell 101 and a middle shell 102, the middle shell 102 including a groove 1021 for placing the windless air guide plate 30. The control mechanism 20 can control the windless air guide plate 30 to switch between a normal air outlet position and a windless air outlet position. The windless air guide plate 30 includes a first movable plate 31 and a second movable plate 32, each having a plurality of ventilation holes. The first movable plate 31 and the second movable plate 32 are rotatably connected to the housing 10 via their respective rotating shafts. When the windless air guide plate 30... When the air is in the normal air outlet position, the windless air guide plate 30 is located in the groove 1021. The windless air guide plate 30, together with the outer shell 101 and the middle shell 102, forms an air channel. The air channel includes a smoothly extending first air outlet channel 12, a second air outlet channel 13, and an air inlet channel 11. The channel wall of the first air outlet channel 12 includes a first movable plate 31, and the channel wall of the second air outlet channel 13 includes a second movable plate 32. When the windless air guide plate 30 is in the windless air outlet position, the first movable plate 31 is located at the air outlet of the first air outlet channel 12, and the second movable plate 32 is located at the air outlet of the second air outlet channel 13.

[0032] The main difference between this embodiment and embodiment 1 is that the middle shell 102 in this embodiment directly separates the outer shell 101 to form the first air outlet channel 12 and the second air outlet channel 13, and does not have the cavity 14 in the embodiment. Therefore, the air outlet area of ​​the windless air conditioning outlet assembly in this embodiment is not as large as that in embodiment 1, and it is not very suitable for use in manually operated air conditioning outlets.

[0033] The control mechanism 20 in this embodiment is similar to that in embodiment 1. The specific structure can be referred to in embodiment 1, and will not be described again in this embodiment.

[0034] Although the present invention has been described with reference to preferred embodiments, those skilled in the art will understand that it is not limited to the description of the above embodiments, and various changes in form and detail may be made within the scope of the claims.
