Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, and more specifically to an automobile air-conditioning air outlet. Background Art

[0002] Car air vents are an important part of car interiors and play a significant role in the comfort of driving. Car air vents need to meet the functional requirements of being able to adjust the wind direction, adjust the air volume, and be sealed.

[0003] For the current air outlet, please refer to the automobile air-conditioning outlet disclosed in publication number CN220615428U, in which a vertical blade group is arranged in the air duct. When the vertical blade group rotates left and right, the airflow passing through the air duct is guided left and right, thereby adjusting the left and right angles of the air outlet. However, there are certain deficiencies in the above-mentioned product: the left and right rotation angles of the blades of the vertical blade group are the same. When the blades rotate to the left or right to the extreme position, at this time, the blades close to the side wall of the air duct will guide a large amount of airflow to the side wall blowing towards the air duct, which will cause airflow backflow or turbulence, etc., resulting in poor air outlet effect. Utility Model Content

[0004] In view of the shortcomings and defects of the prior art, an automobile air-conditioning outlet with a simple structure and good air outlet effect is provided.

[0005] An air outlet for an automobile air conditioner, comprising:

[0006] An air outlet housing, wherein the air outlet housing is provided with an air duct;

[0007] A first air guide blade group and a second air guide blade group are arranged in the air duct, and the blades of the first air guide blade group and the blades of the second air guide blade group are arranged along the width direction of the air duct;

[0008] The blades of the first air guide blade group and the blades of the second air guide blade group rotate in a first direction, or in a second direction opposite to the first direction, to adjust the air outlet angle of the air duct;

[0009] Wherein, when the blades of the first air guide blade group and the blades of the second air guide blade group rotate in the first direction to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group is greater than the rotation angle of the blades of the second air guide blade group;

[0010] When the blades of the first air guide blade group and the blades of the second air guide blade group rotate in the second direction to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group is smaller than the rotation angle of the blades of the second air guide blade group.

Therefore, a smaller amount of the airflow acted on by the second air guide blade group acts on the left side wall of the shell, avoiding a large amount of airflow blowing to the left side wall of the shell to cause backflow, so that the air outlet effect of the airflow is better;

[0015] When the blades of the first air guide blade group and the blades of the second air guide blade group rotate in the second direction (right or downward) to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group is smaller than the rotation angle of the blades of the second air guide blade group;

DETAILED DESCRIPTION

[0046] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] See also Figure 1-10 As shown, an automobile air-conditioning outlet comprises:

[0048] The air outlet housing 1 is provided with an air duct 1.1;

[0049] A first air guide blade group 2 and a second air guide blade group 3 are arranged in the air duct 1.1. The blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 are arranged along the width direction of the air duct 1.1.

[0050] The blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 rotate in a first direction, or in a second direction opposite to the first direction, to adjust the air outlet angle of the air duct 1.1;

[0051] When the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 rotate in the first direction to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group 2 is greater than the rotation angle of the blades of the second air guide blade group 3;

[0052] When the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 rotate in the second direction to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group 2 is smaller than the rotation angle of the blades of the second air guide blade group 3 .

[0053] After adopting the above structure, the automobile air conditioner air outlet of the utility model has the following advantages compared with the prior art: the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 are arranged along the width direction of the air duct 1.1,

[0054] The blades of the first air guide blade group 2 are arranged close to the right side wall (upper side wall) of the air duct 1.1, and the blades of the second air guide blade group 3 are arranged close to the left side wall (lower side wall) of the air duct 1.1.

[0055] When the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 rotate in the first direction (left or upward) to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group 2 is smaller than the rotation angle of the blades of the second air guide blade group 3;

[0056] At this time, the first air guide blade group 2 guides the airflow to the left (upward), and the second blade group also guides the airflow to the left (upward), but the guiding angle of the second air guide blade group 3 to the airflow is smaller than the guiding angle of the first air guide blade group 2 to the airflow, so a smaller amount of the airflow acted on by the second air guide blade group 3 acts on the left side wall of the shell, avoiding a large amount of airflow blowing to the left side wall of the shell to cause backflow, so that the air outlet effect of the airflow is better;

[0057] When the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 rotate in the second direction (right or downward) to the extreme position of the air outlet angle, the rotation angle of the blades of the first air guide blade group 2 is smaller than the rotation angle of the blades of the second air guide blade group 3;

[0058] At this time, the first air guide blade group 2 guides the airflow to the right (downward), and the second blade group also guides the airflow to the right (downward), but the guiding angle of the first air guide blade group 2 to the airflow is smaller than the guiding angle of the second air guide blade group 3 to the airflow. Therefore, a smaller amount of the airflow affected by the first air guide blade group 2 acts on the right side wall of the shell, avoiding a large amount of airflow blowing to the right side wall of the shell to cause backflow, thereby making the air outlet effect better.

[0059] As an improvement of the present utility model, the number of blades in the first wind guide blade group 2 is several, and they are arranged in linkage with each other;

[0060] The second air guide blade group 3 has a plurality of blades which are arranged in linkage with each other. After the above improvement, multiple blades are used to act on the airflow at the same time, so that the airflow is fine and the effect is better.

[0061] As an improvement of the present invention, the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 are both vertically arranged in the air duct 1.1;

[0062] The first direction is the left direction of the blade around its rotation axis;

[0063] The second direction is the direction of the blades moving to the right around their rotation axis. The above improvement is an implementation of the first wind guide blade group 2 and the second wind guide blade group 3, in which the blades of the first wind guide blade group 2 and the blades of the second wind guide blade group 3 swing left and right around their rotation axis to guide the airflow to the left and right.

[0064] Of course, the first direction may also be the upward direction around the rotation axis, and the second direction may also be the downward direction around the rotation axis. In the second embodiment, the blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 swing up and down around the rotation axis to guide the airflow up and down. The second embodiment does not provide specific instructions and drawings.

[0065] Please refer to the third embodiment of the present application.

[0066] The tail portion of the air duct 1.1 is divided into a first air outlet channel 1.11 and a second air outlet channel 1.12 which are arranged opposite to each other in the upper and lower parts;

[0072] In this embodiment, the airflow after passing through the first air guide blade group 2 and the second air guide blade group 3 enters the first air outlet channel 1.11 or the second air outlet channel 1.12, and is further guided up and down by the first air outlet channel 1.11 or the second air outlet channel 1.12.

[0073] Further, when the guide plate 4 rotates to a position between the first air outlet channel 1.11 and the second air outlet channel 1.12, at this time, the guide plate 4 does not enter the first air outlet channel 1.11 or the second air outlet channel 1.12, and the opening of the first air outlet channel 1.11 or the second air outlet channel 1.12 cannot be adjusted.

[0082] In the initial position state, the first air guide blade group 2 is in the first left air outlet position, and the second blade group is in the second left air outlet position, which is the extreme position state of the left air outlet angle;

[0083] The driving plate 5 rotates along the pivot direction B, the first cam groove 5.1 cooperates with the first transmission pin 6.1, and drives the first air guide blade group 2 to have a first concentrated air outlet position, a first rightward air outlet position, and a first air volume closed position in sequence through the first transmission member 6;

[0085] The first air guide blade group 2 enters the first air volume closing position, and the second air guide blade group 3 enters the second air volume closing position. The blades of the first air guide blade group 2 and the blades of the second air guide blade group 3 are rotated to the right to overlap to close the air duct 1.1.

[0086] The driving disc 5 rotates in the opposite direction along the pivot direction B, and the first air guide blade group 2 and the second air guide blade group 3 enter the above positions in opposite order.

[0087] As an improvement of the utility model, the first cam groove 5.1 and the second cam groove 5.2 are arranged in a quasi-annular manner end to end, and the first cam groove 5.1 includes a section, b section, c section, and d section, wherein the distance between the a section and the center point is constant, the distance between the b section and the center point is gradually reduced, the distance between the c section and the center point is gradually reduced, and the distance between the d section and the center point is gradually reduced; wherein the a section corresponds to the stroke of the first leftward air outlet position of the first air guide blade group 2, the b section corresponds to the stroke of the first concentrated air outlet position of the first air guide blade group 2, the c section corresponds to the stroke of the first rightward air outlet position of the first air guide blade group 2, and the d end corresponds to the stroke of the first air volume closing position of the first air guide blade group 2;

[0098] A knob is provided at the front end of the joystick 8, and the knob can be used by the user to operate the joystick 8;

[0099] When the operating lever 8 drives the ball head rotating rod 9 to swing up and down, the transmission member can drive the fork 9.11 to swing up and down synchronously.

The third swing arm 4.1 is coaxially connected to one side arm of the guide plate 4. The rotation of the third swing arm 4.1 can rotate the guide plate 4 along the axis A to adjust the up and down air outlet angles.

[0100] As an improvement of the present utility model, the joystick 8 drives the ball head rotary rod 9 to swing left and right relative to the housing.
