Description

Technical Field

[0001] This invention relates to the field of vehicle air 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] The structural difference between windless vehicle air conditioning vents and traditional vehicle air conditioning vents is quite simple: the former includes a windless baffle. By switching the position of the windless baffle, one can switch between windless airflow and normal airflow. However, adding a windless baffle requires an additional control mechanism for the vehicle's air conditioning vents. For electric vehicle air conditioning vents, an additional motor is needed, which significantly increases costs. Summary of the Invention

[0004] To avoid the shortcomings of the prior art, the present invention provides a windless air conditioning vent assembly and vehicle, which allows the windless adjustment mechanism to share a set of control mechanisms with the original airflow adjustment mechanism.

[0005] This invention proposes a windless air conditioning vent assembly, comprising a housing, an airflow regulating mechanism, a windless regulating mechanism, and a control mechanism. An air channel is formed inside the housing, and the airflow regulating mechanism is disposed within the air channel to regulate the airflow. The control mechanism includes a turntable, a first transmission assembly, and a second transmission assembly. The turntable is connected to the airflow regulating mechanism and the windless regulating mechanism via the first and second transmission assemblies. The turntable can rotate sequentially to a first position, a second position, and a third position, with an airflow regulating range formed between the first and second positions. The airflow regulating mechanism can move sequentially to... The system has a first extreme position, a preset intermediate position, and a second extreme position. The windless adjustment mechanism can move sequentially to the normal air outlet position and the windless air outlet position. When the turntable rotates within the airflow adjustment range, it drives the airflow adjustment mechanism to move between the first and second extreme positions to adjust the airflow, while the windless adjustment mechanism remains in the normal air outlet position. When the turntable rotates from the second position to the third position, it drives the airflow adjustment mechanism to move from the second extreme position to the preset intermediate position, and simultaneously drives the windless adjustment mechanism to move from the normal air outlet position to the windless air outlet position.

[0006] Furthermore, the airflow regulating mechanism is one of the following: up-down wind direction regulating mechanism, left-right wind direction regulating mechanism, or air volume regulating mechanism.

[0007] Furthermore, the turntable includes a first track section and a second track section. The first end of the first transmission component is configured to be connected to the airflow adjustment mechanism, and the second end is configured to be able to move along the first track section when the turntable rotates. The first end of the second transmission component is configured to be connected to the windless adjustment mechanism, and the second end is configured to be able to move along the second track section when the turntable rotates.

[0008] Preferably, the first trajectory section is a first trajectory groove, and the second trajectory section is a second trajectory groove.

[0009] Furthermore, the first transmission assembly includes a transmission crank, which includes a shaft portion as a first end and a first connecting post as a second end; the shaft portion is connected to the airflow regulating mechanism and can move synchronously with the airflow regulating mechanism; the shape of the first connecting post matches the shape of the first track groove.

[0010] Furthermore, the air duct includes an air inlet duct, a first air outlet duct, and a second air outlet duct; the windless adjustment mechanism includes a first movable plate and a second movable plate, each having several ventilation holes; when the windless adjustment mechanism is in the windless air outlet position, the first movable plate and the second movable plate are located at the air outlets of the first air outlet duct and the second air outlet duct, respectively; when the windless adjustment mechanism is in the normal air outlet position, the first movable plate and the second movable plate are respectively close to the duct wall of the first air outlet duct and the second air outlet duct, or respectively serve as part of the duct wall of the first air outlet duct and the second air outlet duct.

[0011] Furthermore, the second transmission assembly includes a linear transmission member, a first crank, a first connecting rod, a second crank, and a second connecting rod. The linear transmission member is connected to the first connecting rod and the second connecting rod, respectively. The first connecting rod is connected to the first crank, the first crank is connected to the first movable plate, the second connecting rod is connected to the second crank, and the second crank is connected to the second movable plate. The linear transmission member includes a second connecting post as a second end, and the shape of the second connecting post matches the shape of the second track groove.

[0012] In one preferred embodiment, the turntable component includes a front side and a back side, with a first track portion and a second track portion respectively disposed on the front side and the back side of the turntable component.

[0013] In another preferred embodiment, the first track portion and the second track portion of the turntable are located on the same side of the turntable, and the second track portion includes a first section and a second section; the second transmission assembly includes two second ends, which are respectively configured to move along the first section and the second section, and when the turntable rotates, at least one of the two second ends can connect with its corresponding section and move along its corresponding section; the tracks of the first track portion, the first section and the second section do not overlap.

[0014] Furthermore, the outer wall of the housing has a linear limiting groove, and the linear transmission component also includes a connecting block. The connecting block is connected to the linear limiting groove to restrict the movement of the linear transmission component to linear movement only.

[0015] Furthermore, it also includes a drive motor, which is connected to the turntable and can drive the turntable to rotate.

[0016] The present invention also proposes a vehicle including the windless air conditioning vent assembly described above.

[0017] The beneficial effect of this invention is that it allows the windless adjustment mechanism to share a control mechanism with the original airflow adjustment mechanism, thereby saving the number of motors and reducing the overall cost of the air outlet. Attached Figure Description

Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example, see attached document Figure 1-8 A windless air conditioning outlet assembly includes a housing 100, an airflow regulating mechanism 300, a windless regulating mechanism 400, a control mechanism 200, and a drive motor 500. An air channel is formed inside the housing 100, which includes an air inlet channel 110, a first air outlet channel 120, and a second air outlet channel 130; the outer wall of the housing 100 has a straight limiting groove 140. An airflow regulating mechanism 300 is installed in the air channel to regulate the airflow in the air channel. In this embodiment, the airflow regulating mechanism 300 includes an up-down wind direction regulating mechanism 310 and a left-right wind direction regulating mechanism 320. The airflow regulating mechanism 300 that shares a drive motor 500 with the windless regulating mechanism 400 is the up-down wind direction regulating mechanism 310. Specifically, the up-down wind direction regulating mechanism 310 is installed in the air inlet channel 110 and includes a guide plate 311. The airflow ratio between the first air outlet channel 120 and the second air outlet channel 130 is adjusted according to the position of the guide plate 311. The windless adjustment mechanism 400 includes a first movable plate 410 and a second movable plate 420, both of which have several ventilation holes. The control mechanism 200 includes a turntable 210, a first transmission assembly, and a second transmission assembly, wherein: The turntable component 210 includes a first track groove 211 and a second track groove 212. The first track groove 211 and the second track groove 212 of the turntable component 210 are located on the same end face of the turntable component 210. The second track groove 212 includes a first sub-groove 2121 and a second sub-groove 2122. The tracks of the first track groove 211, the first sub-groove 2121 and the second sub-groove 2122 do not overlap. The first transmission assembly includes a transmission crank 220, which includes a shaft portion as the first end of the first transmission assembly and a first connecting post 221 as the second end of the first transmission assembly. The transmission crank 220 is connected to the air guide plate 311 through its shaft portion and can drive the air guide plate 311 to rotate synchronously. The transmission crank 220 is connected to the turntable component 210 through the first connecting post 221. The shape of the first connecting post 221 matches the shape of the first track groove 211 and can move along the first track groove 211 when the turntable component 210 rotates. The second transmission assembly includes a linear transmission component 230, a first crank 231, a first connecting rod 232, a second crank 233, and a second connecting rod 234. The linear transmission component 230 includes two second connecting posts 2301 and a connecting block 2302, which serve as the second ends of the second transmission assembly. The linear transmission component 230 is connected to the turntable component 210 through the second connecting posts 2301. The shapes of the two second connecting posts 2301 are respectively matched with the shapes of the first slot 2121 and the second slot 2122, and they can move along the first slot 2121 and the second slot 2122 respectively. When the turntable component 210 rotates, at least one of the two second connecting posts 2301 can connect with its corresponding slot and move along its corresponding slot. The connecting block 2302 is connected to the linear limiting groove 140 on the outer wall of the housing 100, so that the turntable component 210 can only drive the linear transmission component 230 to move in a straight line. Restricting the linear movement of the linear transmission component 230 during the design process can simplify the motion calculation of the second transmission assembly. Linear transmission component 230 is connected to first connecting rod 232 and second connecting rod 234 respectively. First connecting rod 232 is connected to first crank 231, and first crank 231 is connected to first movable plate 410. First crank 231 includes a rotating shaft portion that serves as the first end of the second transmission component. First crank 231 is connected to first movable plate 410 through its rotating shaft portion and can drive first movable plate 410 to rotate synchronously. Second connecting rod 234 is connected to second crank 233, and second crank 233 is connected to second movable plate 420. Second crank 233 includes a rotating shaft portion that also serves as the first end of the second transmission component. Second crank 233 is connected to second movable plate 420 through its rotating shaft portion and can drive second movable plate 420 to rotate synchronously. The drive motor 500 is connected to the turntable component 210 and can drive the turntable component 210 to rotate sequentially to the first position, the second position and the third position. An airflow adjustment range is formed between the first position and the second position. The turntable component 210 can drive the air guide plate 311 to move sequentially to the first limit position, the preset middle position and the second limit position, and drive the first movable plate 410 and the second movable plate 420 to move sequentially to the normal air outlet position and the windless air outlet position. When the turntable 210 rotates in the airflow adjustment range, the turntable 210 drives the air guide plate 311 to move between the first limit position and the second limit position to adjust the airflow ratio between the first air outlet channel 120 and the second air outlet channel 130, that is, to adjust the up and down airflow direction of the air conditioning outlet assembly. At the same time, the positions of the first movable plate 410 and the second movable plate 420 remain unchanged and are always in the normal air outlet position. In this embodiment, the normal air outlet position, that is, the first movable plate 410 and the second movable plate 420, respectively serve as part of the air duct wall of the first air outlet channel 120 and the second air outlet channel 130, and play the role of guiding the airflow. When the turntable 210 rotates from the second position to the third position, the turntable 210 drives the air guide plate 311 to move from the second extreme position to the preset middle position, and at the same time drives the first movable plate 410 and the second movable plate 420 to move from the normal air outlet position to the windless air outlet position. In this embodiment, the windless air outlet position means that the first movable plate 410 and the second movable plate 420 are located at the air outlets of the first air outlet channel 120 and the second air outlet channel 130, respectively. The ventilation holes on the first movable plate 410 and the second movable plate 420 can disperse the airflow into small streams of airflow.

[0029] Working principle of the windless air conditioning outlet assembly in this embodiment: When the air conditioning vent assembly needs to output air normally, such as Figure 3-5 As shown, continuously, at this time, the drive motor 500 drives the turntable 210 to rotate between the first position and the second position, that is, the airflow adjustment range. The corresponding air guide plate 311 rotates between the first limit position and the second limit position. Since the first movable plate 410 and the second movable plate 420 are always in the normal air outlet position, they will not affect the airflow. Therefore, the position change of the air guide plate 311 can adjust the airflow between the first air outlet channel 120 and the second air outlet channel 130, that is, adjust the up and down air outlet direction of the air conditioning air outlet assembly. When the air conditioning vent assembly needs to be switched to windless airflow, such as Figure 5-7 As shown, at this time, the drive motor 500 drives the turntable component 210 from... Figure 5 The second position rotated to Figure 7 In the third position, during the rotation, the air guide plate 311 first moves from... Figure 5 Rotate to the second extreme position Figure 6 The preset intermediate position ensures that the airflow between the first air outlet duct 120 and the second air outlet duct 130 is the same, and then the first movable plate 410 and the second movable plate 420 move from... Figure 6 Turn the normal air outlet position to Figure 7The air outlet position without a wind sensation is achieved by the ventilation holes on the first movable plate 410 and the second movable plate 420, which disperse the airflow into small streams. The preset intermediate position can be the middle position between the first and second extreme positions of the air guide plate 311 within its travel range, or the middle position of the air guide plate 311 corresponding to the middle air direction between the two extreme air directions of the air conditioning outlet assembly, or any position between the first and second extreme positions. However, this position should not affect the air outlet effect of the air conditioning outlet assembly when there is no wind sensation.

[0030] In this embodiment, the rotation of the air guide plate 311 to the preset middle position and the rotation of the first movable plate 410 and the second movable plate 420 to the windless air outlet position are not synchronized because of the trajectory conflict limitation between the trajectory slots. After actual optimization, if there is no conflict between the first trajectory slot 211 and the second trajectory slot 212, then the second trajectory slot 212 does not need to be split into the first sub-slot 2121 and the second sub-slot 2122. When the air conditioner air outlet assembly switches to windless air outlet, the air guide plate 311, the first movable plate 410 and the second movable plate 420 can also rotate synchronously.

[0031] In this embodiment, the air conditioning vent assembly allows the windless adjustment mechanism 400 to share a single control mechanism 200 and drive motor 500 with the original up and down airflow adjustment mechanism 310, which can reduce the overall cost of the vent.

[0032] In another embodiment, when the windless adjustment mechanism 400 is in the normal air outlet position, the first movable plate 410 and the second movable plate 420 can also be close to the air duct wall of the first air outlet channel 120 and the second air outlet channel 130, respectively. However, in this solution, the first movable plate 410 and the second movable plate 420 will hinder the airflow to some extent.

[0033] In another embodiment, the turntable 210 includes a front and a back, and the first track groove 211 and the second track groove 212 are respectively provided on the front and back of the turntable 210. However, this solution will not cause the track of the first track groove 211 and the second track groove 212 to conflict. However, the increase in the thickness of the turntable 210 will cause the size of the air conditioning vent assembly to increase, which in turn requires the vehicle to provide more installation space for the air conditioning vent assembly.

[0034] It should be noted that the airflow regulating mechanism 300 in a typical air conditioning vent assembly includes one or more of the following: a vertical airflow regulating mechanism 310, a horizontal airflow regulating mechanism 320, and an airflow regulating mechanism. In this embodiment, the airflow regulating mechanism 300 includes a vertical airflow regulating mechanism 310 and a horizontal airflow regulating mechanism 320, wherein the windless regulating mechanism 400 shares a drive motor 500 with the vertical airflow regulating mechanism 310. It is understood that in other embodiments, the windless regulating mechanism 400 may share a drive motor 500 with the horizontal airflow regulating mechanism 320, or it may share a drive motor 500 with the airflow regulating mechanism. Both the horizontal airflow regulating mechanism 320 and the airflow regulating mechanism have rotating blades or airflow guides similar to the air guide plate 311 in this embodiment; therefore, there is no technical problem, only a need to modify the transmission components in the control mechanism 200 according to structural adaptability.
