Description

Technical Field

[0001] This utility model relates to the field of vehicle interior technology, and in particular to a novel foot-blowing air duct system. Background Technology

[0002] As an important means of transportation in modern society, driver comfort is a crucial indicator that influences people's choices. Currently, the air duct design at the footwell of mainstream vehicles has two major flaws:

[0003] 1. Limited airflow coverage: Traditional air vents are designed only for the right foot, with small openings and narrow guides, so the left leg rarely receives airflow from the air conditioner. This affects the driver's comfort when starting the car, especially in high or low temperatures.

[0004] 2. Cumbersome fan speed adjustment: Most fan speed adjustment solutions are directly adjusted through the air conditioning system, making it impossible to adjust the fan speed when the leg area needs to be adjusted separately.

[0005] Therefore, there is an urgent need for a simple air supply system that can evenly cover both feet. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a new foot-blowing air duct system that addresses the shortcomings of the existing technology. By increasing the length of the outer shell, the system ensures that the lateral airflow radiation range covers the driver's left and right foot areas, thus solving the problem of limited wind access for the driver's single foot. At the same time, the insert controls the flow cross-section size of the airflow channel, solving the problem of cumbersome wind speed adjustment.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A novel foot-blowing duct system includes:

[0009] An air guide channel includes an outer shell and an inner side plate; the outer shell is formed by multiple outer side plates forming a funnel-shaped structure, and the inner side plates are symmetrically arranged inside the outer shell; an airflow groove is formed between the outer side plates and the inner side plates;

[0010] The duct is connected at one end to the air outlet of the air conditioner and at the other end to the air guide channel;

[0011] The adjustment mechanism includes a plate, a slider, and a connecting rod with the same width as the airflow channel; wherein, two plates are provided, which pass through the inner side plate and are slidably connected to the inner side plate, and the bottom of both plates are connected to the slider via the connecting rod;

[0012] The slider is driven by a connecting rod to insert or remove the insert from the airflow slot.

[0013] One end of the connecting rod is provided with a first pin, and one end of the insert is provided with a first pin hole;

[0014] The first pin is inserted into the first pin hole, and the two are rotatably connected.

[0015] One end of the connecting rod is provided with a second pin hole, and one end of the slider is provided with a groove, in which second pins are symmetrically arranged on the left and right sides;

[0016] The second pin hole is inserted into the second pin shaft, and the two are rotatably connected.

[0017] The pipeline is a flexible air duct.

[0018] An operating hole is provided at the bottom of the slider.

[0019] The withdrawn state of the insert completely opens the airflow channel, while the inserted state completely closes the airflow channel.

[0020] The first pin is a columnar structure, and the first pin hole is a matching round hole structure.

[0021] The length of the outer shell covers the driver's left and right foot areas.

[0022] This utility model has the following beneficial effects:

[0023] This utility model provides a novel foot-blowing air duct system. By increasing the distance between the left and right side walls, it ensures that the lateral airflow radiation range covers the driver's left and right foot areas, and the height extension of the front and rear side walls further covers the front and rear areas of the feet. At the same time, the airflow channel is fully opened when the insert is pulled out and partially closed when inserted, thereby controlling the size of the airflow passage cross section. Based on Pascal's principle, this system plays an auxiliary role in controlling the wind speed. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] As an important means of transportation in modern society, the comfort of the driver is a crucial indicator that influences people's choices. Currently, the air ducts designed for the footwell in mainstream vehicles have the following shortcomings: Limited coverage of the air vents: Traditional air vents are designed only for the right foot, with small openings and narrow guides, so the left leg rarely receives airflow from the air conditioner. This affects the driver's comfort when starting the car in high or low temperatures; Complex structure of the air ducts: A few solutions that cover both feet require separate ducts 3 and air vents 2, increasing the number of car parts and assembly costs.

[0034] To solve the above problems, refer to Figures 1 to 6 This application provides a novel foot-blowing air duct system, comprising: an air guide channel 4, including an outer shell and an inner side plate 9; the outer shell is formed into a funnel-shaped structure by multiple outer side plates 8, and the inner side plates 9 are symmetrically arranged inside the outer shell; an airflow groove 10 is formed between the outer side plates 8 and the inner side plates 9; a pipe 3, one end of which is connected to the air outlet 2 of an air conditioner 1, and the other end of which is connected to the air guide channel 4; an adjustment mechanism, including inserts 11 with the same width as the airflow groove 10, a slider 7, and a connecting rod 14; wherein, two inserts 11 are provided, passing through the inner side plate 9 and slidably connected to the inner side plate 9, and the bottom of both inserts 11 are connected to the slider 7 through the connecting rod 14; the slider 7 drives the inserts 11 to insert into or withdraw from the airflow groove 10 through the connecting rod 14.

[0035] The outer casing covers the driver's left and right foot areas, and the airflow channel 10 is divided into two parts to evenly distribute airflow to both legs. Meanwhile, the duct 3 is a flexible corrugated pipe, increasing the ease of maintenance of the airflow channel 4 and avoiding situations where maintenance is inconvenient due to the size limitations of the duct 3. The airflow channel 4 is fixed to the vehicle with clips or screws, ensuring stable fixation and quick-release maintenance. The extended state of the insert 11 completely opens the airflow channel 10, while the inserted state completely closes it.

[0036] Furthermore, the air conditioner 1 discharges airflow outward through the air outlet 2, and the duct 3 guides the airflow from the air conditioner 1 to the air guide channel 4. At this time, under the action of the side panel, the cross-sectional area of ​​the airflow from the air conditioner 11 expands and diffuses to the air outlet 2 covering the driver's legs. At this time, by controlling the movement of the slider 7, the connecting rod 14 drives the insert 11 to move inward and outward along the direction of the airflow cut-off groove 10. When it is necessary to control the wind speed to decrease, the insert 11 is pulled out; when it is necessary to control the wind speed to increase, the insert 11 is inserted. In this way, this application can also play an auxiliary role in controlling the wind speed by controlling the size of the cross-section of the airflow.

[0037] As a preferred embodiment of the novel foot-blowing duct system provided in this application, one end of the connecting rod 14 is provided with a first pin 13, and one end of the insert 11 is provided with a first pin hole 12; the first pin 13 is inserted into the first pin hole 12, and the two are rotatably connected. To improve the smoothness of rotation, the first pin 13 has a columnar structure, and the first pin hole 12 has a matching circular hole structure. Therefore, when the insert 11 moves, the stability of its insertion or removal direction can be ensured.

[0038] As a preferred embodiment of the novel foot-blowing air duct system provided in this application, one end of the connecting rod 14 is provided with a second pin hole 15, and one end of the slider 7 is provided with a groove, in which second pins 16 are symmetrically arranged; the second pin hole 15 is inserted into the second pin 16, and the two are rotatably connected. Thus, when the slider 7 moves in this application, its up-and-down sliding direction can be kept stable.

[0039] As a preferred embodiment of the novel foot-blowing duct system provided in this application, an operating hole 6 is provided at the bottom of the slider 7 to facilitate control. By inserting a hand into the operating hole 6, the slider 7 can be controlled to slide up and down. Alternatively, the operating hole 6 can be replaced with a handle.

[0040] Working principle:

[0041] First, pull down the slider 7, causing it to move the connecting rod 14 down, thereby opening the airflow groove 10 from the insert 11.

[0042] At this time, the air conditioner 1 discharges airflow outward through the air outlet 2, and the duct 3 guides the airflow to the air guide channel 4; at this time, under the action of the side panel, the cross-sectional area of ​​the airflow expands and spreads to cover the driver's legs.

[0043] Furthermore, after completing the initial temperature adjustment, if cooling is needed in summer and additional airflow is required due to clothing covering the legs, the slider 7 can be pushed upwards, causing the connecting rod 14 to move upwards. This causes the insert 11 to close part of the ventilation space of the airflow slot 10, thereby increasing the wind speed.

[0044] At the same time, the leg air outlet needs to be turned off. Push the slider 7 all the way down so that the insert 11 completely seals the airflow slot 10.

[0045] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
