Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to a thin air outlet device. Background Technology

[0002] The air conditioning vents of a car are an important component inside the vehicle. Chinese patent CN116160824A discloses a car air conditioning vent. Traditional conventional air vents have a minimum width of about 30mm, resulting in a relatively large opening. Traditional conventional air vents have visible blade grilles; the more grilles there are, the more complex the appearance, which is not conducive to the current market trend towards simplicity. Furthermore, the airflow direction adjustment of traditional conventional air vents generally relies on the left-right and up-down movement of the grille blades. Since the airflow direction is basically determined by the ductwork, the blades' ability to adjust the airflow direction is limited. Especially with thin air vents, which typically only have one horizontal blade, the airflow direction cannot be completely adjusted based on the blade angle. Therefore, there is an urgent need to design a thin air vent that offers better airflow direction adjustment and a narrower opening width. Summary of the Invention

[0003] This invention addresses the technical problem in existing automotive air conditioning vents that are difficult to simultaneously achieve good airflow direction adjustment and have a small vent width, by providing a thin air outlet device.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0005] A thin air outlet device includes: a front bracket, a front air duct, a rear air duct, and a swing assembly;

[0006] The two ends of the front bracket are rotatably mounted on the vehicle body via pins, and the front bracket is provided with air vents;

[0007] The front air duct is a flexible duct, and the front end of the front air duct is confined within the air outlet; there is a certain lateral movement gap between the front end of the front air duct and the air outlet.

[0008] The rear end of the front duct is connected to the air supply equipment via the rear duct;

[0009] The swing assembly is connected to the front air duct, and the swing assembly drives the front air duct to swing up and down and left and right.

[0010] Furthermore, the swing assembly includes: a first driving component, a second driving component, a duct rotation bracket, a duct sliding bracket, and a limiting slider;

[0011] The front air duct passes through the air duct sliding bracket and is connected to the air duct sliding bracket;

[0012] The duct rotating bracket is positioned above the duct sliding bracket; the duct rotating bracket has a vertically penetrating groove, the direction of which is perpendicular to the direction of the front duct; a limiting slider is provided at the upper part of the groove, the limiting slider is connected to the duct sliding bracket via a connector passing through the groove, the connector being able to slide freely along the groove; mounting pins are provided at both ends of the duct rotating bracket, and the duct rotating bracket is rotatably mounted on the vehicle body via the mounting pins;

[0013] The movable end of the first driving component is connected to one end of the duct rotating bracket, and the first driving component is used to push and pull the duct rotating bracket in the up and down direction;

[0014] The second driving component is disposed on the duct rotating bracket, and the movable end of the second driving component passes through the slide groove and is connected to the duct sliding bracket. The second driving component is used to push and pull the duct sliding bracket in the left and right directions.

[0015] Furthermore, the first driving component and the second driving component are electric push-pull rods or miniature linear motors.

[0016] Furthermore, the front and rear air ducts are flexible corrugated pipes.

[0017] Furthermore, it also includes: the shell;

[0018] The front bracket is assembled on the front side of the housing;

[0019] The front and rear air ducts are assembled inside the housing.

[0020] The housing is provided with mounting connectors that mate with the vehicle body.

[0021] Furthermore: the front air duct is provided with multiple sections;

[0022] The air outlet is provided with sub-air outlets that correspond one-to-one with the front air duct; the front end of the front air duct is limited to the corresponding sub-air outlet.

[0023] Furthermore, the width of the air outlet is 15mm.

[0024] The thin air outlet device provided by the present invention has at least the following beneficial effects or advantages:

[0025] The thin air outlet device provided by this invention has a front bracket rotatably mounted on the vehicle body via a pin, and an air outlet is provided on the front bracket. The front air duct is a flexible pipe, with its front end confined within the air outlet. There is a certain clearance between the front end of the front air duct and the air outlet. The rear end of the front air duct is connected to the air supply equipment via a rear air duct. A swing component is connected to the front air duct, and the swing component drives the front air duct to swing up and down and left and right. This thin air outlet device, through the swing component, can drive the front air duct to bend to a certain extent in the up-down and left-right directions. Because the front bracket is rotatably mounted on the vehicle body via a pin, the bending of the front air duct in the up-down direction can be transmitted to the front end of the front air duct, causing the front end of the front air duct to drive the front bracket to rotate, thus achieving up-down adjustment of the airflow direction. Furthermore, because there is a certain clearance between the front end of the front air duct and the air outlet, the bending of the front air duct in the left-right direction can be transmitted to the front end of the front air duct, causing the left-right orientation of the front end of the front air duct to change, thus achieving left-right adjustment of the airflow direction. This device does not rely on grille plates for airflow adjustment, so the width of the air vent can be controlled within 15mm. It combines the advantages of good airflow adjustment and small air vent width, which can further improve the aesthetics of the car's air conditioning vent. Attached Figure Description

[0035] This invention addresses the technical problem in existing automotive air conditioning vents that are difficult to simultaneously achieve good airflow direction adjustment and have a small vent width, by providing a thin air outlet device.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0037] This invention discloses a thin air outlet device, such as... Figure 1 As shown, it mainly includes: a front bracket 1, a front air duct 2, a rear air duct 3, and a swing assembly 4. The two ends of the front bracket 1 are rotatably mounted on the vehicle body via pins, so that the front bracket 1 can be adjusted in the vertical direction; the front bracket 1 is provided with an air outlet, which is used to provide air conditioning air or natural hot and cold air to the interior of the car; in this embodiment, the width of the air outlet is 15mm.

[0038] The front duct 2 is a flexible pipe, such as a bend-resistant flexible corrugated pipe or hose. The front end of the front duct 2 is confined within the air outlet. In practical applications, flexible connectors or snap-fit ​​devices can be used to connect the front end of the front duct 2 to the air outlet, ensuring a certain degree of mobility while preventing the front duct 2 from detaching from the air outlet. There is a certain lateral clearance between the front end of the front duct 2 and the air outlet to allow for left-right movement. The rear end of the front duct 2 is connected to the air supply equipment, such as an automotive air conditioner, via the rear duct 3.

[0039] The swing assembly 4 is connected to the front air duct 2. The swing assembly 4 drives the front air duct 2 to swing up and down and left and right. During the swinging process, the swing assembly 4 drives the front air duct 2 to swing, thereby changing the direction of the front end of the front air duct 2, thus achieving the adjustment of the air direction.

[0040] Specifically, such as Figure 2As shown, the swing assembly 4 includes: a first driving component 41, a second driving component 42, a duct rotation bracket 43, a duct sliding bracket 44, and a limiting slider 45. The front duct 2 passes through the duct sliding bracket 44 and is connected to it. The duct rotation bracket 43 is positioned above the duct sliding bracket 44; the duct rotation bracket 43 has a vertically penetrating groove 46, the direction of which is perpendicular to the direction of the front duct 2. A limiting slider 45 is provided at the upper part of the groove 46, and the limiting slider 45 is connected to the duct sliding bracket 44 through the groove 46 via a connector 47, which can slide freely along the groove 46; the duct rotation bracket 43 and the duct sliding bracket 44 are assembled together by the limiting slider 45 and the connector 47. Mounting pins are provided at both ends of the duct rotation bracket 43, and the duct rotation bracket is rotatably mounted on the vehicle body via the mounting pins.

[0041] The movable end of the first driving component 41 is connected to one end of the duct rotating bracket 43. The first driving component 41 is used to push and pull the duct rotating bracket 43 in the up and down direction. In this embodiment, the first driving component 41 adopts an electric push-pull rod or a micro linear motor.

[0042] The second drive component 42 is mounted on the duct rotating bracket 43. The movable end of the second drive component 42 passes through the slide groove 46 and is connected to the duct sliding bracket 44. The second drive component 42 is used to push and pull the duct sliding bracket 44 in the left and right directions. In this embodiment, the second drive component 42 also adopts an electric push-pull rod or a micro linear motor.

[0043] To achieve integration of the components and to protect the front air duct 2 and the rear air duct 3, the thin air outlet device provided by the present invention further includes: a housing 5. A front bracket 1 is assembled on the front side of the housing 5; the front air duct 2 and the rear air duct 3 are assembled inside the housing 5; and the housing 5 is provided with mounting connectors that cooperate with the vehicle body.

[0044] To further improve the control accuracy of the airflow direction, a preferred embodiment of the present invention can be configured as multiple front air ducts 2, with each air outlet having a sub-air outlet corresponding to one of the front air ducts 2; the front end of the front air duct 2 is confined within its corresponding sub-air outlet. During the airflow direction adjustment process, the swing component 4 can drive each front air duct 2 to bend to a certain extent, thus the direction of the front end of each front air duct 2 changes independently, further improving the control accuracy of the airflow direction.

[0045] like Figures 2-7 As shown, the working process of the thin air outlet device provided in this embodiment of the invention is as follows:

[0046] I. Upward airflow: The first electric push-pull rod pushes the duct rotating bracket 43 backward; the duct rotating bracket 43 rotates counterclockwise; the duct rotating bracket 43 causes the front duct 2 to bend; the bending of the front duct 2 causes the front bracket 1 to rotate clockwise, so that the air outlet on the front bracket 1 faces upward.

[0047] II. Downward airflow: The first electric push-pull rod pulls the duct rotating bracket 43 forward; the duct rotating bracket 43 rotates clockwise; the duct rotating bracket 43 causes the front duct 2 to bend; the bending of the front duct 2 causes the front bracket 1 to rotate counterclockwise, so that the air outlet on the front bracket 1 faces downward.

[0048] III. Blowing air to the left: The second electric push-pull rod pushes the air duct sliding bracket 44 to the right; the air duct sliding bracket 44 drives the rear end of the front air duct 2 to move to the right; the front end of the front corrugated pipe deflects to the left.

[0049] IV. Blowing air to the right: The second electric push-pull rod pushes the air duct sliding bracket 44 to the left; the air duct sliding bracket 44 drives the rear end of the front air duct 2 to move to the left; the front end of the front air duct 2 deflects to the right.

[0050] V. Center air blowing: The first and second electric push-pull rods are reset, making the front air duct 2 a straight pipe, and the air outlet on the front bracket 1 and the front air duct 2 are in the center position.

[0051] The thin air outlet device provided in this embodiment of the invention has at least the following beneficial effects or advantages:

[0052] The thin air outlet device provided in this embodiment of the invention has an air outlet on the front bracket; the front air duct is a flexible pipe, and the front end of the front air duct is confined within the air outlet; there is a certain clearance between the front end of the front air duct and the air outlet; the rear end of the front air duct is connected to the air supply equipment through the rear air duct; the swing component is connected to the front air duct, and the swing component drives the front air duct to swing up and down and left and right. This thin air outlet device, through the swing component, can drive the front air duct to bend to a certain extent in the up-down and left-right directions; since the front bracket is rotatably mounted on the vehicle body via a pin, the bending of the front air duct in the up-down direction can be transmitted to the front end of the front air duct, causing the front end of the front air duct to drive the front bracket to rotate, thereby achieving adjustment in the up-down direction and thus achieving adjustment of the airflow direction. Furthermore, since there is a certain lateral clearance between the front end of the front air duct and the air outlet, the bending of the front air duct in the left-right direction can be transmitted to the front end of the front air duct, causing the left-right orientation of the front end of the front air duct to change, thereby achieving adjustment of the airflow direction. This device does not rely on grille plates for airflow adjustment, so the width of the air vent can be controlled within 15mm. It combines the advantages of good airflow adjustment and small air vent width, which can further improve the aesthetics of the car's air conditioning vent.
