Description

Technical Field

[0001] This invention relates to the technical field of vehicles, and more particularly to an air outlet airflow control mechanism and a vehicle having the air outlet airflow control mechanism. Background Technology

[0002] With the development of intelligent and electronically controlled vehicles, the direction of airflow from car vents and their operation have evolved from manual to electric and voice-controlled. This all requires a drive motor, and currently, the mainstream market still requires a motor for each operation: one motor for left / right airflow, one for up / down airflow, and one for airflow cutoff. This means a car needs at least 12 motors, leading to increased costs and requiring more space, posing significant challenges to structural design. In many cases, space constraints force the abandonment of electric air vent solutions. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an air outlet airflow control mechanism and a vehicle having the air outlet airflow control mechanism, so as to achieve the functions of controlling the cut-off of airflow, adjustment of the up and down blowing angle, and up and down sweeping with as few actuators as possible, or even only one actuator.

[0011] In the aforementioned airflow control mechanism for the air outlet, the guide plate is rotatably connected to the middle of the first channel, and the guide plate is configured to rotatably shield the upper or lower part of the first channel.

[0012] The aforementioned air outlet airflow control mechanism is operable in a first position, a second position, and a third position.

[0064] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] In the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "lateral", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0066] Please see Figures 1 to 16 As shown, a preferred embodiment of an air outlet airflow control mechanism is illustrated, comprising: a first channel 1, a second channel 2, and a third channel 3, wherein the second channel 2 and the third channel 3 are respectively connected to the first channel 1; the first channel 1 is provided with a rotatable guide plate 11;

[0067] The second channel 2 and the third channel 3 are respectively equipped with a second damper 21 and a third damper 31 that can be rotatably opened or closed; the drive disk 4 is configured to control the rotation of the guide vane 11, the second damper 21 and the third damper 31; the drive disk 4 is configured such that when the guide vane 11 rotates, the second damper 21 and the third damper 31 are stationary; the drive disk 4 is configured such that when the second damper 21 and / or the third damper 31 rotate, the guide vane 11 is stationary.

[0068] In this embodiment, the aforementioned "rotation of the guide vane 11" and "rotation of the second damper 21 and / or the third damper 31" can be continuous rotation, intermittent rotation, or not completely continuous rotation, as long as they can achieve rotation.

[0070] In a preferred embodiment, the second damper 21 and the third damper 31 may operate synchronously or asynchronously.

[0071] In other words, it can also be understood that when the second damper 21 is activated, the deflector 11 is stationary; when the third damper 31 is activated, the deflector 11 is stationary; and when the second damper 21 and the third damper 31 are activated simultaneously, the deflector 11 is also stationary.

[0072] It should be foreseen that although the present invention is preferably applicable to the air vents of vehicles, and preferably to gases, it can obviously also be applied to other fluids besides gases.

[0073] Furthermore, in a preferred embodiment, the guide plate 11 is rotatably connected to the middle of the first channel 1, and the guide plate 11 is configured to rotatably shield the upper or lower part of the first channel 11. It should be noted that the aforementioned shielding is not equivalent to sealing. In one preferred embodiment, the guide plate 11 operably seals the upper or lower part of the first channel 11, while in another preferred embodiment, the guide plate 11 does not serve a sealing function, but only serves to guide the flow of fluid.

[0074] Furthermore, as a preferred embodiment, the airflow control mechanism at the air outlet is operably positioned in a first position, a second position, and a third position;

[0079] Furthermore, as a preferred embodiment, during the transition of the airflow control mechanism from the first position to the second position, the guide vane 11 remains stationary, while the second damper 21 and the third damper 31 rotate continuously.

[0080] Furthermore, as a preferred embodiment, during the operation of the air outlet airflow control mechanism from the second position to the third position, the guide vane 11 rotates continuously, while the second damper 21 and the third damper 31 remain stationary.

[0081] Obviously, the first, second, and third positions mentioned above can also be set in the reverse order.

[0082] Furthermore, as a preferred embodiment, the drive disk 4 is configured as follows:

[0083] When the drive disc 4 rotates in the first direction, the air outlet airflow control mechanism moves sequentially from the first position, the second position to the third position.

[0084] When the drive disc 4 rotates in the second direction opposite to the first direction, the airflow control mechanism at the air outlet moves sequentially from the third position, the second position to the first position.

[0085] In this embodiment, please refer to Figures 5 to 13 As shown, when the drive disc 4 rotates counterclockwise, the air outlet airflow control mechanism moves sequentially from the first position, the second position to the third position; when the drive disc 4 rotates clockwise, the air outlet airflow control mechanism moves sequentially from the third position, the second position to the first position.

[0092] In a further embodiment of the present invention, the first channel 1 is located on one side of the housing 5, the second channel 2 and the third channel 3 are located on the other side of the housing 5, and the second channel is located above the third channel.

[0093] In a further embodiment of the present invention, the guide plate shaft 12, the second shaft 22, and the third shaft 32 are rotatably fixed relative to the housing 5. That is, the positions of the guide plate shaft 12, the second shaft 22, and the third shaft 32 relative to the housing 5 do not change, but they can rotate relative to the housing 5.

[0094] In a further embodiment of the present invention, the housing 5 includes at least a first housing component 51 and a second housing component 52.

[0095] In a further embodiment of the present invention, the first housing component 51 is open at both ends, having a first end with a larger diameter in the vertical direction and a second end with a smaller diameter in the vertical direction.

[0096] In a further embodiment of the present invention, at least a portion of the second housing component 52 is disposed inside the first housing component 51. Specifically, at least a portion of the second housing component 52 is disposed inside the first end of the first housing component, thereby dividing the first end of the first housing component into a first space and a second space communicating with the second end of the first housing component. The first space is the second channel 2, and the second space is the third channel 3.

[0097] In a further embodiment of the present invention, the second housing component 52 has an upper inclined plate 521 and a lower inclined plate 522 connected to each other, the second damper 21 is operably attached to the upper inclined plate 521 to open the second channel 2, and the third damper 31 is operably attached to the lower inclined plate 522 to open the third channel 3.

[0098] In a further embodiment of the present invention, the second damper 21 is operably fitted to the inner wall of the first housing component 51 to close the second channel 2, and the third damper 31 is operably fitted to the inner wall of the first housing component 51 to close the third channel 3.

[0099] In a further embodiment of the present invention, the second housing component 52 divides the first housing component 51 to form a horizontally oriented "Y"-shaped air duct, which includes the first channel 1, the second channel 2 and the third channel 3 described above.

The guide plate shaft 12 is matched with the first track groove 41, the second shaft 22 is matched with the second track groove 42 and the third shaft 32 is matched with the third track groove 43.

[0101] In this embodiment, the rotation of the three blades (i.e., the guide plate 11, the second damper 21 and the third damper 31) can be achieved by the cooperation of the track groove and the slider.

[0102] In a preferred embodiment, only one drive disk 4 is included, which is actuated by a single driver such as a motor, and the rotation of the three blades can be controlled by this single drive disk 4.

[0103] In another preferred embodiment, to ensure synchronized driving force at both ends of the blades, two symmetrically arranged drive disks 4 can be provided, each actuated by a driver. The rotation of the three blades can be controlled by the two drivers and the two drive disks 4. Although two drivers are used in this scheme, it is still better than the scheme where each blade receives one driver.

[0104] In another possible embodiment, in order to provide synchronized driving forces at both ends of the blade, two symmetrically arranged drive disks 4 can be provided, both drive disks 4 being actuated by the same driver. For example, one drive disk 4 is directly actuated by the same driver, and the other drive disk 4 is indirectly actuated by the same driver through a transmission assembly.
