Description

Technical Field

[0001] This utility model relates to the field of vehicle damper technology, and in particular to a damper drive mechanism and a vehicle. Background Technology

[0002] The air vent damper drive mechanism is a core component of the vehicle's air conditioning distribution system. Its function is to precisely switch between air conditioning modes (such as face, foot, and defrost) by controlling the opening and closing angle of the dampers. With the increasing sophistication of vehicle configurations, there is a growing demand for individual control of each damper in the rear modes. However, the rear air vents are typically equipped with CCB brackets on both sides, and various electrical devices are located above and below the vents, making the placement of the damper drive mechanism difficult. Furthermore, due to the fixed relative positions of the damper drive mechanism and the damper, the overall space occupied is often excessive. Utility Model Content

[0006] Drive components;

[0007] The transmission assembly includes a drive component that can rotate the damper shaft to adjust the opening angle of the damper. The transmission assembly includes a rack with a first tooth segment and a second tooth segment. The first tooth segment meshes with a portion of the transmission component, and the second tooth segment meshes with another portion of the transmission component. The first tooth segment is oriented towards a first direction, and the second tooth segment is oriented towards a second direction.

[0017] Optionally, it also includes a support shell, the drive unit is connected to the support shell, the damper is rotatably connected to the support shell, the support shell surrounds an air outlet, the damper is disposed inside the air outlet, and the damper is used to adjust the size of the ventilation opening inside the air outlet.

[0018] Another objective of this invention is to provide a vehicle that can improve the flexibility of spatial arrangement and increase space utilization.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a damper drive mechanism, including a drive component and a transmission assembly. The drive component can drive the damper's shaft to rotate via the transmission assembly, thereby adjusting the damper's opening and closing angle. The transmission assembly includes a rack with a first tooth segment and a second tooth segment. The first tooth segment meshes with a portion of the transmission assembly's transmission components, and the second tooth segment meshes with the remaining portion of the transmission assembly's transmission components.

By incorporating a rack with both a first and second tooth segment in the transmission assembly, and with the first and second tooth segments facing an angle, the flexibility of the positional relationship between the drive component and the damper is improved. This allows the drive component and transmission assembly to be positioned within the remaining space of numerous supports and electrical devices, improving space utilization. Furthermore, it simplifies the structure of the transmission assembly, preventing the need to increase the number of transmission components to accommodate the positional relationship between the drive component and the damper, which would otherwise lead to increased costs and reduced assembly efficiency. Therefore, this damper drive mechanism can help improve the flexibility of space layout and increase space utilization.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] The air vent damper drive mechanism is a core component of the vehicle's air conditioning distribution system. Its function is to precisely switch between air conditioning modes (such as face, foot, and defrost) by controlling the opening and closing angle of the dampers. With the increasing sophistication of vehicle configurations, there is a growing demand for individual control of each damper in the rear modes. However, the rear air vents are typically equipped with CCB brackets on both sides, and various electrical devices are located above and below the vents, making the placement of the damper drive mechanism difficult. Furthermore, due to the fixed relative positions of the damper drive mechanism and the damper, the overall space occupied is often excessive.

[0037] Therefore, this embodiment provides a damper drive mechanism 100 to solve the above problems. The damper drive mechanism 100 can help improve the flexibility of space layout and improve space utilization.

[0038] like Figures 1-5 As shown, the damper drive mechanism 100 of this embodiment includes a drive member 1 and a transmission assembly. The drive member 1 can drive the rotating shaft 201 of the damper 200 to rotate via the transmission assembly, thereby adjusting the opening and closing angle of the damper 200. The transmission assembly includes a rack 2, on which a first tooth segment 21 and a second tooth segment 22 are provided. The first tooth segment 21 meshes with a portion of the transmission components of the transmission assembly, and the second tooth segment 22 meshes with the remaining portion of the transmission components. The first tooth segment 21 is oriented towards a first direction, and the second tooth segment 22 is oriented towards a second direction. The angle between the first and second directions is α, satisfying: 0° < α < 180°. Figure 5 In the diagram, direction ab is the first direction, and direction cd is the second direction.

[0039] By incorporating a rack 2 with both a first tooth segment 21 and a second tooth segment 22 in the transmission assembly, and with the first tooth segment 21 and the second tooth segment 22 oriented at an angle, the design improves the flexibility of the positional relationship between the drive component 1 and the damper 200. This allows the drive component 1 and the transmission component to be positioned within the remaining space of numerous supports and electrical devices, thus increasing space utilization. Furthermore, it simplifies the structure of the transmission assembly, preventing the need to increase the number of transmission components to accommodate the positional relationship between the drive component 1 and the damper 200, which would otherwise lead to increased costs and reduced assembly efficiency. Therefore, this damper drive mechanism 100 enhances the flexibility of spatial arrangement and improves space utilization.

[0040] Optionally, in some embodiments, α satisfies: 60°≤α≤120°, meaning the rack 2 can achieve a large change in transmission angle. Of course, in other embodiments, the value of α can be adjusted according to the actual spatial arrangement near the damper 200.

[0041] Optionally, in this embodiment, α satisfies: α = 90°. Optionally, the rack 2 is disposed on one side of the right housing 302, the direction in which the first tooth segment 21 faces is parallel to the plate surface of the right housing 302, that is, the transmission component meshing with the first tooth segment 21 is sequentially arranged along the plate surface of the right housing 302, and the direction in which the second tooth segment 22 faces is perpendicular to the plate surface of the right housing 302, that is, the transmission component meshing with the second tooth segment 22 is sequentially arranged along the direction perpendicular to the plate surface of the right housing 302. The specific details of the right housing 302 will be described below.

[0042] like Figure 5 As shown, optionally, the extension direction of the first tooth segment 21 and the extension direction of the second tooth segment 22 are both parallel to the length direction of the rack 2, which allows the first tooth segment 21 and the second tooth segment 22 to have a relatively long length when the width of the rack 2 is small. The first tooth segment 21 and the second tooth segment 22 are spaced apart along the length direction of the rack 2.

[0043] Optionally, the rack 2 further includes an assembly section 23, which is located between the first tooth segment 21 and the second tooth segment 22 along the length of the rack 2. Optionally, the damper drive mechanism 100 also includes a fixing member 5, which is connected to the right housing 302. The rack 2 is clamped between the fixing member 5 and the plate surface of the right housing 302. The fixing member 5 can restrict the position of the rack 2, prevent the rack 2 from moving in the direction of detaching from the right housing 302, and ensure stable transmission of the rack 2.

[0044] Optionally, a guide groove is provided on the assembly section 23 and / or the side without toothed sections. The guide groove is located on the side facing the fixing member 5. A guide protrusion is provided on the fixing member 5. The guide protrusion is movably located in the guide groove so that the fixing member 5 can further limit the movement direction of the rack 2.

[0045] like Figure 2 and Figure 3 As shown, optionally, the transmission assembly further includes a first transmission member 3, which is connected to the output end of the drive member 1. The first transmission member 3 has a first meshing tooth 311 circumferentially arranged on the side wall of its first end 31 along its own axial direction. The first meshing tooth 311 meshes with the first tooth segment 21 for transmission. That is, the drive member 1 drives the first transmission member 3 to rotate, and the first transmission member 3 drives the first tooth segment 21 to move along its own length direction.

[0046] Optionally, the axial direction of the first transmission member 3 is perpendicular to the surface of the right housing 302. Optionally, the side wall of the second end 32 of the first transmission member 3 along its own axial direction has a limiting groove, and the output end of the driving member 1 has a connecting groove with a limiting protrusion on the side wall of the connecting groove. The second end 32 is inserted into the connecting groove, and the limiting protrusion is located in the limiting groove. That is, the output end of the driving member 1 is stably connected to the first transmission member 3 and rotates synchronously. Optionally, the second end 32 of the first transmission member 3 is splined to ensure that the force exerted on the second end 32 by the output end of the driving member 1 is uniform and consistent along the circumference of the second end 32, so as to prevent excessive local stress and easy failure.

[0047] Optionally, the transmission assembly further includes a second transmission member 4, which is connected to the rotating shaft 201. A second meshing tooth 411 is circumferentially provided on the side wall of the third end 41 of the second transmission member 4 along its own axial direction. The second meshing tooth 411 meshes with the second tooth segment 22. That is, when the first tooth segment 21 moves along its own length direction, the second tooth segment 22 can move synchronously along its own length direction. The second tooth segment 22 drives the second transmission member 4 to rotate, thereby causing the second transmission member 4 to drive the rotating shaft 201 of the damper 200 to rotate. The rotating shaft 201 can then drive the door panel of the damper 200 to rotate along the axial direction of the rotating shaft 201, thereby adjusting the tilt angle of the door panel. Since the door panel is located inside the air outlet 305, the size of the ventilation opening inside the air outlet 305 can be adjusted when the tilt angle of the door panel changes.

[0048] Optionally, the second transmission component 4 has a positioning groove on the side wall of its fourth end 42 along its own axial direction, and a positioning groove 2011 is formed on one end face of the rotating shaft 201 along its own length direction. The side wall of the positioning groove 2011 has a positioning protrusion, and the fourth end 42 is inserted into the positioning groove 2011, with the positioning protrusion located within the positioning groove. That is, the second transmission component 4 and the rotating shaft 201 are stably connected and rotate synchronously. Optionally, the fourth end 42 of the second transmission component 4 is splined to ensure that the force applied by the fourth end 42 to the rotating shaft 201 is uniform and consistent along the circumference of the rotating shaft 201, so as to prevent excessive local stress and easy failure.

[0049] This embodiment also provides a vehicle, including a damper 200 and the aforementioned damper drive mechanism 100, wherein the damper drive mechanism 100 is used to adjust the opening and closing angle of the damper 200.

[0050] Optionally, the vehicle also includes a support shell 300, which includes a left shell 301, a right shell 302, an upper shell 303, and a lower shell 304 that are connected to each other. The damper drive mechanism 100 is disposed on the right shell 302. Optionally, the drive component 1 is connected to the support shell 300, specifically to the right shell 302.

[0051] Optionally, the damper 200 is rotatably connected to the support housing 300, specifically rotatably connected to the upper housing 303 and the lower housing 304. The support housing 300 surrounds an air outlet 305, specifically formed by the upper housing 303 and the lower housing 304. The damper 200 is disposed within the air outlet 305, with the rotating shaft 201 perpendicular to the airflow direction of the air outlet 305. The damper 200 is used to adjust the size of the ventilation opening within the air outlet 305.

[0052] This vehicle can improve the flexibility of space layout and increase space utilization.
