Automobile up-and-down type double-channel air port

Abstract

This utility model relates to a dual-channel air vent for automobiles, with two air guide units symmetrically arranged on both sides of a central partition. Each air guide unit has an upper blade shaft with a track. A knob is located on the track, and a fork is fixedly connected to the knob, which is then inserted into the blade assembly. The knob can rotate the blade assembly horizontally when moving along the track, and vertically when the upper blade shaft rotates. This utility model uses two air guide units, physically isolating the air duct through a central partition, dividing the air outlet into upper and lower layers, achieving stratified airflow without interference. The horizontal swing angle of the lateral guide blades is extended, significantly expanding the coverage of horizontal airflow. The upper and lower longitudinal guide blade assemblies can also be independently adjusted, achieving independent left and right airflow diffusion. The combined horizontal swing angle increases the coverage area, accommodating passengers in different seating positions, and is extremely convenient to operate, simplifying the operation steps by more than 50%.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a dual-channel air vent for automobiles. Background Technology

[0002] With the booming development of the automotive industry and the rapid popularization of private cars, car users are placing higher demands on vehicle comfort, air conditioning performance, and the convenience of related structures. Currently, for the same seat, car air conditioning vents generally adopt a single-channel airflow structure, whose main technical limitation is a narrow range of airflow adjustment.

[0003] Traditional air vents adjust airflow direction using single-channel horizontal guide vanes. Relying solely on a limited number of vanes for fine-tuning in both horizontal and vertical directions, this results in airflow concentrated on specific areas of the passenger's body (such as the face), failing to meet the need for simultaneous coverage of a larger area. When passengers need to adjust the airflow to different body parts simultaneously (such as the face and knees), existing structures cannot provide independent airflow for different zones, requiring repeated manual adjustments of the vent angle—a cumbersome and unpleasant experience. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a dual-channel air vent for automobiles, which can effectively improve passenger comfort and simplify the adjustment method.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dual-channel air vent for automobiles, comprising an outer frame, wherein two air guiding units are provided in the outer frame, the two air guiding units are symmetrically arranged on both sides of a central partition, each air guiding unit having an upper blade rotating shaft, a track provided on the upper blade rotating shaft, a knob provided in the track, a fork fixedly connected to the knob and inserted into the blade assembly through the fork, the knob being able to drive the blade assembly to rotate horizontally when moving along the track, and being able to drive the blade assembly to rotate vertically when the upper blade rotating shaft rotates.

[0006] In the above technical solution, the blade group includes multiple blades, all of which are mounted on a linkage rod and are linked with the shift fork via the linkage rod.

[0007] In the above technical solution, the blade in the middle is provided with a fork fixing rod, and the fork is fixedly connected to the fork fixing rod.

[0008] In the above technical solution, the outer frame includes a first frame and a second frame, and the middle partition is disposed between the first frame and the second frame and is fixed to the first frame and the second frame by a buckle.

[0009] In the above technical solution, the two ends of the upper blade shaft are connected to the outer frame on the corresponding side.

[0010] In the above technical solution, the partition is provided with a rotating shaft seat, and the rotating shaft inside the blade is mounted on the rotating shaft seat.

[0011] In the above technical solution, the lower two sides of the dial are provided with rotation limiting plates, and the upper blade shaft is clamped between the two rotation limiting plates.

[0012] In summary, the advantages of this utility model's technical solution compared to traditional methods are as follows: This utility model employs two air guiding units, creating an independent upper and lower dual-air duct system. The air ducts are physically isolated by a central partition, dividing the air outlet into upper and lower layers. The upper air duct corresponds to the upper body area of ​​the passenger (such as the head and shoulders), while the lower air duct covers the lower body area (such as the chest and knees), achieving stratified airflow without interference.

[0013] Independent airflow guiding mechanism: Both the upper and lower channels are equipped with lateral and longitudinal guide vane assemblies. The horizontal swing angle of the lateral guide vanes is extended, significantly expanding the horizontal airflow coverage; the upper and lower longitudinal guide vane assemblies can also be adjusted independently to achieve independent left and right airflow diffusion.

[0014] Independent adjustment of the upper and lower air vents increases the effective air delivery height range, simultaneously meeting the needs of passengers' heads and knees. The combined horizontal swing angle further expands the coverage area, accommodating passengers in different sitting positions.

[0015] Moreover, it is very easy to operate. The independent control mode reduces the number of repeated adjustments and simplifies the operation steps by more than 50%. Attached Figure Description
