Description

Technical Field

[0001] This utility model relates to the field of automotive air vent technology, and more specifically to the structure of vehicle air vent blades. Background Technology

[0002] In the field of automotive interior functional components, most air vent front blades are assembled from a housing, blades, connecting rods, and levers to adjust the airflow direction. Typically, the front blades only serve to adjust the airflow direction, such as flipping left / right or up / down to a predetermined position. However, gaps still exist in the air vent, making it aesthetically unappealing when integrated with the surrounding environment. For example, CN221794342U discloses an automatically adjusting front blade design for automotive air conditioning vents, where multiple front blades flip upwards or downwards in parallel, but cannot achieve a completely closed state. Similarly, CN216184363U discloses an automotive air conditioning vent, and CN108422834A discloses a self-closing automotive vent designed to prevent whistling under high wind pressure. These solutions use adjacent blades overlapping to achieve vent closure. While this achieves the goal of closing the vent and integrating it with the interior environment, the blades' expansion and contraction in hot and cold environments can produce abnormal noise, and the manufacturing and assembly processes are more complex.

[0003] Therefore, the market urgently needs an air outlet structure that provides a high level of user experience and matches the blades with interior environmental components. Utility Model Content

[0004] To address the technical problems existing in the air outlet blades of the prior art, this utility model proposes a vehicle-mounted air outlet blade structure, comprising:

[0005] The air outlet housing has an air inlet and an air outlet, forming an air outlet channel between the air inlet and the air outlet;

[0006] A front blade assembly is disposed at the air outlet of the air outlet housing, and the front blade assembly includes multiple blades.

[0007] A linkage structure, wherein the first movable end is connected to the front blade assembly;

[0008] A knob is connected to the air outlet housing and located on one side of the air outlet. The knob is equipped with a lever, which is connected to the second movable end of the linkage structure.

[0009] The knob is designed to be rotated by the user and controls multiple blades to rotate between a first angle and a second angle via a linkage structure. At the second angle, all the blades are perpendicular to the axis of the air outlet and are located in the same plane, covering the air outlet.

[0010] Preferably, along the width direction of the blade, both ends of the blade are configured to have smooth arcuate surfaces, and when all the blades are at the second angle, adjacent blades are in contact with each other.

[0011] Preferably, the width of the air outlet is defined as B, the width of each blade is A, and the total number of blades is C. Then the width of the air outlet is B = A * C.

[0012] Preferably, when the blades rotate to a third angle between the first angle and the second angle, all the blades are parallel to the axial direction of the air outlet.

[0013] Preferably, the linkage structure includes a linkage and a movable plate. The first end of the linkage is fixed to the blade and disposed in the positioning groove of the air outlet housing, and the second end is connected to the first insertion hole of the movable plate. When the movable plate moves, the linkage can rotate relative to the positioning groove, causing the blade to change angle.

[0014] Preferably, the movable plate is provided with a second insertion hole, which is an oblong hole. The lever of the knob is inserted into the oblong hole. When the knob is rotated, it drives the movable plate to move along the arrangement direction of the blades.

[0015] Preferably, the length direction of the waist-shaped hole is perpendicular to the arrangement direction of the blades.

[0016] Preferably, the connecting rod includes a first shaft portion, a connecting rod portion, and a second shaft portion. The first shaft portion and the second shaft portion are located at both ends of the connecting rod portion. The first shaft portion is located in the positioning groove, and the second shaft portion is inserted into the first insertion hole.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] The air vent structure proposed in this utility model allows multiple blades to rotate within a target angle range controlled by a single knob, satisfying the adjustment requirements of the air vent direction. Furthermore, all blades can be adjusted to be perpendicular to the air vent axis, meaning all blades are adjusted to be in a plane and cover the air vent. This structure can form a harmonious interior style with the surrounding interior components, making it more aesthetically pleasing and in line with the current style requirements of automotive interiors.

[0026] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0027] Combination Figures 1 to 3 As shown, this utility model proposes a vehicle-mounted air outlet blade structure, including an air outlet housing 10, a front blade group 20, a connecting rod structure 30 and a knob 40. The air outlet housing 10 has an air inlet and an air outlet 11, forming an air outlet channel between the air inlet and the air outlet 11.

[0028] The air outlet 11 can be a rectangular structure.

[0029] Furthermore, the front blade assembly 20 is located at the air outlet 11 of the air outlet housing 10, and the front blade assembly 20 includes multiple blades. Let the width of the air outlet be B, the width of each blade be A, and the total number of blades be C, then the width of the air outlet B = A * C.

[0030] Optional, Figure 1 The device includes three blades. The length of the three blades is along the length of the air outlet, and the width of the blades is along the width of the air outlet 11. The width of the three blades is exactly equal to the width of the air outlet 11.

[0031] Furthermore, the first movable end of the linkage structure 30 is connected to the front blade assembly 20, the knob 40 is connected to the air outlet housing 10 and located on one side of the air outlet 11, and the knob 40 is provided with a lever 41, which is connected to the second movable end of the linkage structure 30.

[0032] The knob 40 is designed to be rotated by the user and controls multiple blades to rotate between a first angle and a second angle via a linkage structure 30. At the second angle, all blades are perpendicular to the axis of the air outlet 11 and are located in the same plane, covering the air outlet 11.

[0033] Combination Figure 1 As shown, when the blades are manipulated to rotate to the second angle, all the blades are perpendicular to the axis of the air outlet 11 and completely cover the air outlet 11, forming a plane. This method forms a unified style with the surrounding interior parts, and the adjacent blades are not nested or overlapped with each other, so they are not prone to abnormal noise due to expansion and contraction.

[0034] In an optional embodiment, the two ends of the blade are configured to have smooth arcuate surfaces along the width direction of the blade, and adjacent blades are in contact with each other when all blades are at the second angle.

[0035] In this way, when adjacent blades make contact through smooth surfaces and produce micro-expansion and contraction, the surfaces of the blades slide relative to each other to reduce compressive stress.

[0036] Combination Figure 2 As shown, when the blades rotate to the third angle between the first angle and the second angle, all the blades are parallel to the axis of the air outlet 11.

[0037] In this way, the airflow from the outlet can blow directly outward along the surface of the blades, with the blowing direction being the axial direction of the outlet 11.

[0038] Combination Figure 3 and Figure 4 As shown, the linkage structure 30 includes a linkage 31 and a movable plate 32. The first end of the linkage 31 is fixed to the blade and is located in the positioning groove 12 of the air outlet housing 10. The second end is connected to the first insertion hole 321 of the movable plate 32. When the movable plate 32 moves, the linkage 31 can rotate relative to the positioning groove 12, causing the blade to change angle.

[0039] Furthermore, the movable plate 32 is provided with a second insertion hole 322, which is an oblong hole. The lever 41 of the knob 40 is inserted into the oblong hole. When the knob 40 is rotated, it drives the movable plate 32 to move along the arrangement direction of the blades.

[0040] Thus, when knob 40 is turned counterclockwise, movable plate 32 moves to the left; when knob 40 is turned clockwise, movable plate 32 moves to the right; when movable plate 32 is at its right limit position and moves to the left, the blade rotates clockwise, i.e., from the second angle (e.g.) Figure 6 As shown, the blade rotates in the first angle direction. When the movable plate 32 is in the left limit position and moves to the right, the blade rotates counterclockwise, that is, from the first angle (…). Figure 5As shown, it rotates in the second angle direction.

[0041] In the above embodiments, the length direction of the waist-shaped hole is perpendicular to the arrangement direction of the blades.

[0042] Specifically, the connecting rod 31 includes a first shaft portion 311, a connecting rod portion 312, and a second shaft portion 313. The first shaft portion 311 and the second shaft portion 313 are located at both ends of the connecting rod portion 312. The first shaft portion 311 is located in the positioning groove 12, and the second shaft portion 313 is inserted into the first insertion hole 321.

[0043] Thus, the first shaft 311 is fixed in the positioning groove 12. When the movable plate 32 moves left and right, the second shaft 313 moves accordingly, which can drive the connecting rod component 312 to swing, that is, the first shaft 311 rotates accordingly.

[0044] In conjunction with the above embodiments, the multiple blades of the air outlet structure proposed in this utility model can be controlled by a single knob to rotate within the target angle range, satisfying the adjustment requirements of the air outlet direction. Furthermore, all blades can be adjusted to a direction perpendicular to the air outlet axis, that is, all blades are adjusted to be in a plane and cover the air outlet. This structure can form a coordinated interior style with the surrounding interior parts, making it more aesthetically pleasing and in line with the current style requirements of automotive interiors.

[0045] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
