Description

Technical Field

[0001] This utility model relates to the field of vehicle air conditioning system technology, and in particular to an adjustable air outlet structure. Background Technology

[0002] The air vents on a vehicle, as the terminals for air conditioning output, typically have adjustable airflow and direction.

[0003] Existing technologies for air vents in vehicles, such as Figure 1 As shown, it typically includes an air outlet body 100 with an air outlet and multiple parallel air guide vanes 200 disposed inside the air outlet. The airflow flows out through the air outlet. By moving the air guide vanes 200 relative to the air outlet and rotating the air outlet body 100, the air outlet angle and the size of the air outlet opening are changed, thereby adjusting the air volume and air direction.

[0004] In the existing technology, the air guide vane 200 under normal air outlet conditions is easily affected by the airflow and its angle is passively and unexpectedly adjusted, making it difficult to maintain the air outlet direction or even causing the air outlet to close unexpectedly and fail to deliver air. When the air outlet is closed by manipulating the air guide vane 200 to fit against the cross-section of the air outlet body 100, there is still a gap between the edge of the air guide vane 200 and the air outlet body 100 in the closed state, which is very easy to generate abnormal noise. In addition, while realizing the adjustment of air volume and air direction of the air conditioner, the air outlet also affects the vehicle interior and is a vehicle exterior component. The air outlet structure of the existing air guide vane 200 appears abrupt and uncoordinated compared to the vehicle interior. Utility Model Content

[0005] To address the aforementioned issues, this application provides a reasonably structured adjustable air vent structure, which enables the adjustment of airflow direction and volume while effectively and reliably maintaining the airflow direction. Furthermore, the overall structure is compact and has good aesthetic consistency, contributing to the improvement and assurance of matching and coordination of vehicle interiors.

[0006] The technical solution adopted in this utility model is as follows: An adjustable air outlet structure includes a housing. The inner wall of the housing forms an inner spherical surface along the circumference. A transmission component is rotatably mounted through the bottom surface of the housing. A universal bracket is fitted at the end of the transmission component located inside the housing. The outer wall of the universal bracket is set as an outer spherical surface along the circumference, and the outer spherical surface is concentrically adapted to the inner side of the inner spherical surface. An air inlet is provided through the bottom surface of the housing. A fan blade assembly is fitted at the air inlet. The end of the transmission component extending through the bottom surface of the housing is poweredly connected to the fan blade assembly, driving the blades in the fan blade assembly to flatten and close the air inlet or form an angle and open the air inlet.

[0007] As a further improvement to the above technical solution: It also includes an upper ring component, which is circumferentially mounted on the housing. The upper ring component and the housing together form a cavity containing an inner spherical surface, and the universal joint is mounted in the cavity.

[0008] The universal joint is either a one-piece molded part or an assembly. The universal joint includes an outer ring, the outer circumferential surface of which is set as an outer spherical surface, and a mounting part is provided at the center of the outer ring. The top of the transmission component is rotatably mounted on the inner side of the mounting part.

[0009] The universal joint also includes an inner ring component concentrically arranged inside the outer ring component, and the outer ring component and the inner ring component are connected by a grid portion; the inner end of the grid portion is connected to the inner ring component, or the inner end of the grid portion extends inward to the inner side of the inner ring component; at least two of the grid portions are connected inward to the mounting portion.

[0010] The bottom surface of the outer ring is fitted with an elastic ring along the circumferential direction.

[0011] The top surface of the mounting part constitutes a force adjustment part, or a knob is mounted on the top surface of the mounting part, and the knob constitutes a force adjustment part.

[0012] The transmission component has a bevel tooth structure at the end that protrudes from the housing. The fan blade assembly includes two sets of blades that swing open and close relative to the housing with the shaft as the center. Each set of blades extends to form an annular bevel tooth portion that meshes with the bevel tooth structure.

[0013] Each set of blades is equipped with rubber on its edge. When the blades are flattened and the air inlet of the casing is closed, the rubber adheres to the air inlet.

[0014] The transmission assembly includes a rotating seat, which is connected to a universal joint via a pivot part one to form a rotating assembly structure with the X-axis as the axial direction. A transmission seat is rotatably mounted on the rotating seat via a pivot part two, and the rotating seat and the transmission seat form a rotating assembly structure with the Y-axis as the axial direction. The transmission seat extends with a protruding column portion that penetrates the housing. A support is installed at the end of the protruding column portion, and the support extends toward the fan blade assembly to form a bevel tooth structure.

[0015] The rotating seat is fitted with damping component one and damping component two. Damping component one has an upper convex arc surface facing the universal joint, and the axis of the upper convex arc surface is consistent with the axis of the pivot part one. The upper convex arc surface is in close contact with the universal joint. Damping component two has a lower convex arc surface facing the transmission seat, and the axis of the lower convex arc surface is consistent with the axis of the pivot part two. The lower convex arc surface is in close contact with the transmission seat.

The surface of the universal joint, the upper ring, and the force adjustment part together constitute the appearance of the air vent. The color and pattern can be matched according to the actual interior design requirements, and the overall appearance is smooth, which effectively improves the user experience. The blade edges are bonded to the air inlet of the casing with rubber, which effectively ensures the reliability of the blades when they are closed and reduces or even avoids the noise caused by gaps.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, an adjustable air outlet structure in this embodiment includes a housing 4. The inner wall of the housing 4 forms an inner spherical surface 10 along the circumference. A transmission component 6 is rotatably installed through the bottom surface of the housing 4. A universal bracket 3 is fitted at the end of the transmission component 6 located inside the housing 4. The outer wall of the universal bracket 3 is set as an outer spherical surface 30 along the circumference. The outer spherical surface 30 is concentrically adapted to the inner side of the inner spherical surface 10. An air inlet 45 is opened through the bottom surface of the housing 4. A fan blade assembly 7 is fitted at the air inlet 45. The end of the transmission component 6 that extends through the bottom surface of the housing 4 is poweredly connected to the fan blade assembly 7, driving the blades 71 in the fan blade assembly 7 to flatten and close the air inlet 45 or form an angle and open the air inlet 45.

[0028] In this embodiment, during actual use, force can be applied to make the universal bracket 3 rotate relative to the housing 4 to adjust the air outlet direction, and the air outlet direction can be effectively and reliably maintained; force can be applied through the transmission component 6 to drive the blades 71 in the fan blade assembly 7 to swing and adjust the air outlet volume, which is convenient to operate.

[0029] In this embodiment, the universal joint 3 is concentrically adapted to the inner spherical surface 10 of the housing 4 via the outer spherical surface 30, thereby realizing the smooth rotation and adjustment of the universal joint 3 relative to the housing 4 in various directions, realizing and ensuring the universal adjustment of the air outlet direction through the universal joint 3, and effectively avoiding the passive change of the air outlet direction due to the influence of wind force.

[0030] It also includes an upper ring 1, which is circumferentially mounted on the housing 4. The upper ring 1 and the housing 4 together form a cavity containing an inner spherical surface 10, and the universal bracket 3 is mounted in the cavity.

[0031] In this embodiment, the cavity is composed of an upper ring 1 and a shell 4, which facilitates processing and assembly and effectively ensures the reliable installation of the universal bracket 3 inside the cavity.

[0032] In this embodiment, the upper ring 1 can be detachably fitted to the housing 4. For example, protrusions 41 are formed on the outer wall of the housing 4 at circumferential intervals, and the upper ring 1 extends toward the protrusions 41 to form lugs 11. The through holes on the lugs 11 and the protrusions 41 fit together to form a detachable snap-fit ​​structure. Figure 2 As shown.

[0033] like Figure 5 As shown, the universal frame 3 is either a one-piece molded part or an assembly part. The universal frame 3 includes an outer ring part 31. The outer circumferential surface of the outer ring part 31 is set as an outer imitation spherical surface 30. A mounting part 34 is provided at the center of the outer ring part 31. The top of the transmission component 6 is rotatably mounted on the inner side of the mounting part 34.

[0034] In this embodiment, the universal joint 3 is adapted to the outer spherical surface 30 and the inner spherical surface 10 of the outer ring 31, and is structurally connected to the transmission component 6 through the installation part 34, so that the action can be transmitted to the transmission component 6 through the universal joint 3, driving the transmission component 6 to rotate relative to the housing 4.

[0035] In this embodiment, the universal joint 3 can be an assembly composed of multiple parts assembled into one unit, including an outer ring 31 and a mounting part 34, which can be matched with the housing 4 and the transmission assembly 6 for installation. In this embodiment, the outer ring 31 and the mounting part 34 can be part of a single part, or they can be assembled from two or more parts.

[0036] The universal joint 3 also includes an inner ring 32 concentrically arranged inside the outer ring 31. The outer ring 31 and the inner ring 32 are connected by a grid portion 33. The inner end of the grid portion 33 is connected to the inner ring 32, or the inner end of the grid portion 33 extends inward to the inner side of the inner ring 32. At least two of the grid portions 33 are connected inward to the mounting portion 34.

[0037] In this embodiment, the grid section 33, combined with the inner ring section 32, forms the grid structure on the inner side of the universal bracket 3, which constitutes the air outlet; the grid section 33 also realizes the reliable connection between the inner ring section 32 and the outer ring section 31, and the grid section 33 realizes the structural reliability of the mounting section 34.

[0038] The bottom surface of the outer ring 31 is fitted with an elastic ring 2 along the circumferential direction.

[0039] In this embodiment, the elastic ring 2 abuts against the inner wall of the housing 4. During the adjustment and swinging process of the universal frame 3 relative to the housing 4, the elastic ring 2 can form a damping between the universal frame 3 and the housing 4, maintaining the operating feel during the adjustment process, and maintaining the state between the universal frame 3 and the housing 4 after adjustment, thus maintaining the current air outlet direction.

[0040] The top surface of the mounting part 34 forms a force adjustment part, or the top surface of the mounting part 34 is equipped with a knob 5, which forms a force adjustment part.

[0041] In this embodiment, the surface of the universal bracket 3, the upper ring 1, and the force adjustment part together constitute the appearance of the air outlet, which can match the color and pattern according to the actual interior design requirements, and the overall appearance is smooth, effectively improving the user experience.

[0042] In this embodiment, the force applied by the force adjustment part can cause the universal bracket 3 to rotate relative to the housing 4, thereby adjusting the air outlet direction and / or adjusting the air volume by driving the fan blade assembly 7 through the transmission assembly 6.

[0043] The transmission assembly 6 has a bevel tooth structure 60 at its end protruding from the housing 4. The fan blade assembly 7 includes two sets of blades 71 that swing open and close relative to the housing 4 with the shaft portion 70 as the center. Each set of blades 71 extends an annular bevel tooth portion 73 that meshes with the bevel tooth structure 60. Figure 7 As shown.

[0044] In this embodiment, the axial direction of the shaft 70 is perpendicular to the axial direction of the bevel tooth structure 60. The rotation of the bevel tooth structure 60 causes the annular bevel tooth 73 that meshes with the bevel tooth structure 60 to move. As a result, the annular bevel tooth 73 drives the blade 71 to swing around the shaft 70, thereby adjusting the angle of the blade 71 in the fan blade assembly 7 and adjusting the airflow through the fan blade assembly 7.

[0045] In this embodiment, the annular conical teeth 73 of the two sets of blades 71 are symmetrically engaged on both sides of the conical tooth structure 60, thereby driving the two sets of blades 71 to adjust their angles through the rotation of the conical tooth structure 60.

[0046] Each blade 71 is equipped with rubber 72 on its edge. When the blade 71 is flattened and closes the air inlet 45 of the housing 4, the rubber 72 is in contact with the air inlet 45.

[0047] In this embodiment, the edge of the blade 71 is attached to the air inlet 45 of the housing 4 via rubber 72, which effectively ensures the reliability of the blade 71 when it is closed and reduces or even avoids the generation of abnormal noise caused by gaps.

[0048] like Figure 6 As shown, the transmission assembly 6 includes a rotating seat 61, which is connected to the universal joint 3 via a pivot 611 to form a rotating assembly structure with the X-axis as the axial direction. The rotating seat 61 is rotatably mounted with a transmission seat 64 via a pivot 612, and the rotating seat 61 and the transmission seat 64 form a rotating assembly structure with the Y-axis as the axial direction. The transmission seat 64 extends with a protruding post 642 that penetrates the housing 4. The axial direction of the protruding post 642 is arranged along the Z-axis. A support 65 is installed at the end of the protruding post 642. The support 65 extends toward the fan blade assembly 7 to form a bevel tooth structure 60.

[0049] In this embodiment, the X, Y, and Z directions are perpendicular to each other. When force is applied to the universal joint 3, it will cause the universal joint 3 to rotate relative to the rotating seat 61 in the X direction with the pivot part 611 as the axial direction, and / or cause the rotating seat 61 to rotate relative to the transmission seat 64 in the Y direction with the pivot part 612 as the axial direction, and / or cause the transmission seat 64 and the protruding column part 642 to rotate relative to the housing 4 in the Z direction as the axial direction and drive the bevel tooth structure 60 to rotate, thereby realizing the directional adjustment of the universal joint 3 relative to the housing 4 and / or the air volume adjustment of the fan blade assembly 7 through the bevel tooth structure 60.

[0050] exist Figure 6 In the embodiment shown, the first pivot part 611 can be a recessed hole opened on the protruding post, and the bottom protruding shaft of the universal joint 3 mounting part 34 is fitted into the recessed hole to form a rotational fitting between the universal joint 3 and the rotating seat 61 with the X direction as the axial direction; the second pivot part 612 can be a protruding shaft, which is fitted into the fitting hole 641 of the transmission seat 64 to form a rotational fitting between the rotating seat 61 and the transmission seat 64 with the Y direction as the axial direction.

[0051] The rotating seat 61 is fitted with a damping element 62 and a damping element 63. The damping element 62 has an upper convex arc surface facing the universal joint 3. The axial direction of the upper convex arc surface is consistent with the axial direction of the pivot part 611. The upper convex arc surface is in close contact with the universal joint 3. The damping element 63 has a lower convex arc surface facing the transmission seat 64. The axial direction of the lower convex arc surface is consistent with the axial direction of the pivot part 612. The lower convex arc surface is in close contact with the transmission seat 64.

[0052] In this embodiment, the damping components 62 and 63 create a damping effect between the rotating seat 61 and the universal joint 3, and between the transmission seat 64 and the rotating seat 61, effectively ensuring the feel and state of the universal joint 3 relative to the housing 4 during angle adjustment.

[0053] In this embodiment, damping component 62 and damping component 63 may be made of materials such as wear-resistant rubber, depending on actual needs.

[0054] exist Figure 8 In the embodiment shown, the air inlet 45 of the housing 4 extends outward to form a convex ring 44. The convex ring 44 has a hole for mounting the shaft 70 of the fan blade assembly 7, so that the fan blade assembly 7 can be installed at the air inlet 45 of the housing 4. In the closed state, the rubber 72 on the edge of the blade 71 of the fan blade assembly 7 is pressed against the inner wall of the convex ring 44, effectively ensuring the closing effect.

[0055] A support ring 42 extends from the housing 4 inside the fan blade assembly 7 via ribs. The protruding post 642 of the transmission assembly 6 is rotatably mounted on the support ring 42 to realize the installation of the transmission assembly 6 on the housing 4. In one embodiment, a groove 43 can be opened circumferentially on the outer end face of the support ring 42. A ring rib that matches the groove 43 extends from the support 65 in the transmission assembly 6 to realize the fitting between the support 65 and the support ring 42.

[0056] The method of using this utility model is as follows: Applying force to the force adjustment part of the universal joint 3 will, depending on the direction of the applied force, cause the universal joint 3 to rotate axially in the X direction relative to the rotating seat 61 with the pivot part 1 611, and / or cause the rotating seat 61 to rotate axially in the Y direction relative to the transmission seat 64 with the pivot part 2 612, thereby adjusting the direction of the universal joint 3 relative to the housing 4 and adjusting the air outlet direction. Of course, a force that rotates axially in the Z direction can also be applied to the universal joint 3, which will cause the transmission seat 64 and the protruding column 642 to rotate axially in the Z direction relative to the housing 4, thereby driving the bevel tooth structure 60 to rotate and causing the blades 71 in the fan blade assembly 7 to swing, thereby adjusting the air volume.

[0057] This invention enables the adjustment of wind direction and air volume while effectively and reliably maintaining the air outlet direction. Furthermore, it features a compact overall structure and good appearance consistency, which helps to improve and ensure the matching and coordination of vehicle interiors.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
