Technical Field

[0001] This utility model relates to the field of automotive air conditioning system technology, and in particular to a natural wind simulation dual-channel automotive electric air outlet device. Background Technology

[0002] Currently, most air vents in automotive air conditioning systems adopt traditional designs, including single-channel structures and fixed airflow adjustment mechanisms. These vents improve airflow by adjusting blade angles or adding diffuser nets, but they are still limited by the discomfort caused by direct airflow. In addition, as consumers' demands for automotive comfort increase, higher requirements are being placed on the airflow distribution, wind speed control, and intelligence of air conditioning vents.

[0003] However, traditional air vents blow directly onto the human body, which can easily lead to discomfort such as dryness and uneven temperature. Furthermore, the single-channel design of the air vents greatly limits the adjustment of airflow direction and speed, making it difficult to meet the needs of different areas inside the vehicle.

The plate drive is equipped with a blade drive plate. The lower end face of the blade drive plate has a lower drive groove group, and one end of the lower channel blade group is located in the lower drive groove group. The upper end face of the blade drive plate has an upper drive groove group. An inner shell upper cover is provided above the lower cover of the inner shell. An upper channel blade group is rotatably arranged between the upper cover of the inner shell and the upper cover of the outer shell. One end of the upper channel blade group is located in the upper drive groove group. A guide plate drive actuator is provided at the end of the lower cover of the outer shell away from the drive plate actuator. A drive disk is provided at the output end of the guide plate drive actuator. The drive shaft and the adjustment are both provided on the drive disk.

The starting end of each of the multiple lower drive slots is provided with a corresponding lower blade crank.

[0008] The upper drive slot group includes multiple upper drive slots.

[0010] The drive disk has a first drive groove and a second drive groove, and the drive shaft is disposed in the first drive groove via a drive cam disk, and the adjustment shaft is disposed in the second drive groove via an adjustment cam disk.

[0011] This utility model discloses a natural wind simulation dual-channel automotive electric air outlet device, comprising a lower outer shell cover, an upper outer shell cover above the lower outer shell cover, an inner lower shell cover inside the lower outer shell cover, a lower channel blade assembly rotatably disposed between the inner lower shell cover and the lower outer shell cover, a drive shaft, an adjusting shaft, and a synchronous drive shaft rotatably disposed within the inner lower shell cover, a guide plate disposed on the drive shaft, a damper disposed on the adjusting shaft, and the synchronous drive shaft being driven by a drive plate actuator, with synchronous drive gears disposed at both ends of the synchronous drive shaft, and a blade drive plate being disposed above the two synchronous drive gears via a rack plate drive, the lower end face of the blade drive plate having a lower drive groove assembly, and the upper end of the blade drive plate having a lower drive groove assembly.

Furthermore, the single-channel structure design greatly limits the adjustment of airflow direction and speed, making it difficult to meet the needs of different areas inside the vehicle.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please see Figures 1 to 8This utility model provides a natural wind simulation dual-channel automotive electric air vent device, including a lower outer shell cover 1, an upper outer shell cover 2 above the lower outer shell cover 1, an inner shell lower cover 3 inside the lower outer shell cover 1, a lower channel blade assembly rotatably disposed between the inner shell lower cover 3 and the lower outer shell cover 1, a drive shaft 5, an adjusting shaft 6, and a synchronous drive shaft 27 rotatably disposed within the inner shell lower cover 3, a guide plate 4 disposed on the drive shaft 5, a damper 7 disposed on the adjusting shaft 6, and the synchronous drive shaft 27 is driven by a drive plate actuator 8, with synchronous drive gears 9 disposed at both ends of the synchronous drive shaft 27, and the two synchronous drive gears 9 are driven by a rack plate 10 above them. A blade drive plate 11 is provided, the lower end face of which has a lower drive groove group, and one end of the lower channel blade group is located in the lower drive groove group. The upper end face of the blade drive plate 11 has an upper drive groove group. An inner shell upper cover 12 is provided above the inner shell lower cover 3, and an upper channel blade group is rotatably arranged between the inner shell upper cover 12 and the outer shell upper cover 2, and one end of the upper channel blade group is located in the upper drive groove group. A guide plate drive actuator 13 is provided at the end of the outer shell lower cover 1 away from the drive plate actuator 8. A drive disk 14 is provided at the output end of the guide plate drive actuator 13, and the drive shaft 5 and the adjustment are both provided on the drive disk 14.

[0024] In this embodiment, through the coordinated operation of components such as the synchronous drive gear 9, the blade drive plate 11, and the drive actuator, the upper channel blade group and the lower channel blade group can be linked to achieve different movement postures of the blades. The change of the trajectory on the blade drive plate 11 realizes the airflow in the upper and lower channels, achieving arbitrary mixing, allowing the outflowing airflow to have different diffusion postures, and the outflowing airflow to change irregularly, resulting in relatively large turbulence.

[0025] Furthermore, the lower channel blade group includes multiple lower channel blade bodies 15, and a lower blade crank 16 is provided above the lower channel blade body 15; the upper channel blade group includes multiple upper channel blade bodies 17, and an upper blade crank 18 is provided above the upper channel blade body 17.

[0026] In this embodiment, this design makes the movement of the blades more precise and controllable. The rotation of the cam disk can drive the blades to swing within a specific angle range, thereby further adjusting the direction and speed of the airflow. This fine adjustment capability allows the air outlet device to better simulate the effect of natural wind and improve passenger comfort.

[0027] Furthermore, the lower drive slot group includes a plurality of lower drive slots 19, the starting end structures of the plurality of lower drive slots 19 are the same, and the middle end and the end end structures of the plurality of lower drive slots 19 are different, and the starting end of the plurality of lower drive slots 19 is provided with a corresponding lower blade crank 16.

[0028] In this embodiment, this design enables the lower channel blade assembly to oscillate along a specific trajectory when driven by the blade drive plate 11, thereby achieving more complex and precise airflow regulation. By changing the shape and length of the drive groove, the oscillation angle and speed of the blades can be further adjusted to meet different airflow requirements. This design improves the flexibility and adaptability of the air outlet device.

[0029] Furthermore, the upper drive slot group includes multiple upper drive slots 20, the starting end structures of the multiple upper drive slots 20 are the same, and the middle end and the end structure of the multiple upper drive slots 20 are different. The starting end of each of the multiple upper drive slots 20 is provided with a corresponding upper blade crank 18.

[0030] In this embodiment, this design enables the upper channel blade assembly to swing along a specific trajectory when driven by the blade drive plate 11, further enhancing the precision and complexity of airflow regulation. Through the coordinated work of the upper and lower channel blade assemblies, the air outlet device can simulate an airflow effect that is closer to natural wind, improving passenger comfort and satisfaction.

[0031] Furthermore, one end of the lower cover 1 of the outer shell has an air inlet end 21, and the guide plate 4 and the damper 7 are both located at the air inlet end 21. The other ends of the upper cover 2 of the outer shell and the lower cover 1 of the outer shell have air outlet ends 22, and the lower channel blade group and the upper channel blade group are both located at the air outlet ends 22.

[0032] In this embodiment, the air inlet 21 and the air outlet 22 are configured as an outer shell and an internal diversion cone, thus forming two channels, upper and lower. The two airflows are coupled at the system outlet. By adjusting the guide plate 5, the airflow strength of the upper and lower channels can be changed, ultimately changing the coupling angle. This design allows the airflow to smoothly enter the air outlet device and, after being adjusted by the upper and lower channel blade groups, flow out of the air outlet 22 in a more comfortable manner. At the same time, this design also considers the uniformity and stability of the airflow, avoiding turbulence or dead zones in the airflow inside the air outlet device, further improving the airflow regulation effect and passenger comfort.

[0033] Furthermore, the drive disk 14 has a first drive groove 23 and a second drive groove 24, and the drive shaft is disposed in the first drive groove 23 via a drive cam disk 25, and the adjustment shaft is disposed in the second drive groove 24 via an adjustment cam disk 26.

[0034] In this embodiment, this design enables the guide vane 4 and the damper 7 to move along a specific trajectory, thereby achieving further regulation of the airflow. By changing the shape and length of the drive groove, the movement speed and angle of the guide vane 4 and the damper 7 can be adjusted to meet different airflow requirements. This design improves the flexibility and adaptability of the air outlet device, enabling the device to better adapt to the needs of different vehicles and passengers.

[0035] In this invention, the synchronous drive shaft 27 is driven by the drive plate actuator 8. The synchronous drive gears 9 at both ends of the synchronous drive shaft 27 drive the rack plate 10 to drive the blade drive plate 11. The lower drive groove group on the lower end face of the blade drive plate 11 drives the lower channel blade group to move, while the upper drive groove group on its upper end face drives the upper channel blade group to move, realizing different movement postures of the blades and changing the direction of the airflow at the outlet. In addition, the guide plate drive actuator 13 controls the guide plate 4 on the drive shaft 5 and the damper 7 on the adjustment shaft 6 through the drive disc 14 to further adjust the air intake volume and airflow direction. This structure, through dual-channel design and dynamic adjustment of blade angle, simulates natural wind, avoids direct blowing, and improves passenger comfort.

[0036] In this invention, when the lower channel blade group is located at the starting end of the lower drive slot group and the upper channel blade group is located at the starting end of the upper drive slot group, the air outlet state of the device is horizontal sweeping; when the lower channel blade group is located at the middle end of the lower drive slot group and the upper channel blade group is located at the middle end of the upper drive slot group, the air outlet state of the device is vertical fluctuating; when the lower channel blade group is located at the end end of the lower drive slot group and the upper channel blade group is located at the end end of the upper drive slot group, the air outlet state of the device is vertical fluctuating and horizontal diffusion. Through the above structural settings, this design has functions such as horizontal sweeping, adjustment of up, down, left and right blowing angles, and closure of the independent air outlet damper 7.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
