Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a transmission structure, an air conditioning vent assembly, and a vehicle. Background Technology

[0002] The vehicle's air conditioning vents are an important component of the vehicle's interior air conditioning system, introducing conditioned or purified air into the passenger compartment. To meet the occupants' needs for different airflow volumes and angles, the vents are equipped with outer blades and inner blades located on the back of the outer blades. The ends of both the outer and inner blades are uniformly formed into the vent's frame and rotatably connected. The rotation axes of the outer and inner blades are perpendicular to each other. Occupants can directly adjust the airflow angle by moving the outer blades. Since the inner blades are located on the back of the outer blades, their airflow angle is adjusted using a lever mounted on the outer blades and a transmission mechanism.

[0003] In related technologies, gears and racks are mainly used as the transmission structure for adjusting the inner blades. The rack is slidably mounted on the horizontal blade, and the gear is mounted on the inner blade. The rack meshes with the gear. Sliding the rack laterally causes the gear to rotate, thereby driving the inner blade to rotate, thus adjusting the air outlet angle of the inner blade.

[0004] When the outer blades rotate, they drive the rack to rotate synchronously, causing a change in the meshing position between the rack and gear. To ensure smooth transmission, the rack and gear must remain engaged at all times. This restricts the relative position of the outer and inner blades; specifically, it limits the relative rotation angle between them. This is to prevent the rack and gear from disengaging or having an insufficient meshing area due to excessive rotation of the outer blades. Utility Model Content

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0044] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the transmission structure 1 provided in an exemplary embodiment of this disclosure. Figure 2 This is a schematic diagram of the kinematic chain variation of the transmission structure 1 provided in an exemplary embodiment of this disclosure in a plane perpendicular to the first direction. Figure 3 This is a schematic diagram of the kinematic chain variation in a plane perpendicular to the second direction for the transmission structure 1 provided in an exemplary embodiment of this disclosure. Embodiments of this application provide a transmission structure 1. The transmission structure 1 includes a first link 11, a second link 12, and a first ring 13. The first link 11 is configured to be rotatably connected to an inner blade 23 about a first direction. The first link 11 is also configured to be movable relative to the inner blade 23 along the first direction. The second link 12 is configured to be slidably connected to an outer blade 22 along a second direction. The first ring 13 is sleeved on the second link 12. The outer peripheral surface of the first ring 13 is hinged to the first link 11. The axis of the hinge is parallel to the second direction.

[0045] It is understandable that the first direction and the second direction are not parallel. Specifically, the first direction and the second direction are perpendicular to each other.

[0046] It can be understood that the first direction is parallel to the first rotation axis of the inner blade 23, and the second direction is parallel to the second rotation axis of the outer blade 22.

[0047] Specifically, at least one end of the first link 11 is configured to be rotatably connected to the inner blade 23 about a first direction. One end of the second link 12 is configured to be slidably connected to the outer blade 22 along a second direction.

[0048] When the air outlet angle of the inner blade 23 needs to be adjusted, the second connecting rod 12 is moved along the second direction to make the second connecting rod 12 move linearly along the second direction. Since the inner blade 23 is rotatably connected to the frame 21 of the vehicle's shaped air outlet 211, the second connecting rod 12, which moves along the second direction, drives the inner blade 23 to rotate around the first rotation axis through the first ring 13 and the first connecting rod 11 in sequence. Figure 2 As shown. Figure 2 In the middle, the second link 12 oscillates upward along the second direction, causing the second link 12 to move from... Figure 2 The position shown in (a) becomes Figure 2The position is shown in (b) in the diagram. When the first link 11 moves closer to the outer blade 22 as the inner blade 23 rotates, the first ring 13 slides on the second link 12 toward the outer blade 22.

[0049] When it is necessary to adjust the air outlet angle of the outer blade 22, a force is applied to the outer blade 22 along the first direction so that the outer blade 22 rotates around the second rotation axis. At this time, the second connecting rod 12 rotates with the rotation of the outer blade 22, and drives the first connecting rod 11 to move relative to the inner blade 23 along the first direction, such as... Figure 3 As shown. Figure 3 In the middle, the outer blade 22 rotates about the second rotation axis, so that the outer blade 22 from Figure 3 The position shown in (c) becomes Figure 3 The position shown in (d) is shown in the diagram.

[0050] In this embodiment, by setting the transmission structure 1 described above to adjust the air outlet angle of the inner blade 23, the influence of adjusting the air outlet angle of the outer blade 22 on the transmission of forces within the transmission structure 1 can be reduced. This reduces the degree to which the relative rotation between the outer blade 22 and the inner blade 23 affects each other, which is beneficial to increasing the range of relative rotation angles between the outer blade 22 and the inner blade 23. Thus, the degree of restriction on the relative position of the outer blade 22 and the inner blade 23 can be reduced.

[0051] Meanwhile, the transmission structure 1 provided in the embodiments of this application has a small internal fit clearance and flexible movement of each component, which can improve the continuity and synchronization of the transmission.

[0052] Furthermore, the internal fit of the transmission structure 1 provided in the embodiments of this application is reliable and not prone to falling off, thereby stably controlling the adjustment of the air outlet angle of the inner blade 23, which helps to improve the reliability of vehicles using the transmission structure 1.

[0053] In addition, the transmission structure 1 provided in the embodiments of this application is simple and small in size, which can help reduce its obstruction to the airflow and improve the smoothness of the air conditioner's airflow.

[0054] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of the first connecting rod 11 provided in an exemplary embodiment of this disclosure. In some embodiments, the first connecting rod 11 is provided with a through hole 111. A first ring 13 is disposed in the through hole 111 and hinged to the hole wall of the through hole 111. In this way, the structural symmetry of the first connecting rod 11 can be improved, thereby improving the stress state of the first connecting rod 11, which is beneficial to improving the continuity and stability of the transmission.

[0055] Please see Figure 4In some embodiments, the first connecting rod 11 includes a first rod 112 and a second ring 113. One end of the first rod 112 is connected to the second ring 113, and the other end is configured to be rotatably connected to the inner blade 23. The inner hole of the second ring 113 is a through hole 111. This design allows the first connecting rod 11 to have a larger size that mates with the first ring 13, while also controlling the dimensions of the remaining parts of the first connecting rod 11. This facilitates control over the volume and material usage of the first connecting rod 11, thereby reducing material costs and assembly difficulty.

[0056] Please see Figure 4 In some embodiments, there are two first rods 112. Along the radial direction of the second ring 113, the two first rods 112 are located on both sides of the second ring 113. In this way, the inner blades 23 at both ends of the first connecting rod 11 can be rotated and connected evenly, thereby increasing the number of connection points between the first connecting rod 11 and the inner blades 23, which helps to improve the continuity of transmission.

[0057] Please see Figure 1 In some embodiments, a first hinge shaft 131 is provided on the outer peripheral surface of the first ring 13. A insertion hole 1131 is provided on the wall of the through hole 111. The end of the first hinge shaft 131 away from the first ring 13 is inserted into the insertion hole 1131. The axis of the first hinge shaft 131 is parallel to a second direction. This simplifies the hinge structure between the first ring 13 and the first connecting rod 11, making it easy to manufacture and assemble.

[0058] Specifically, the hinge shaft passes through the second ring 113 from the outside of the second ring 113 and is interference-fitted into the first ring 13.

[0059] Please see Figure 1 In some embodiments, the through hole 111 is an elliptical hole, the longest diameter of which is parallel to the first direction.

[0060] It is understandable that the second link 12 needs to swing along the first direction within the through hole 111 as the outer blade 22 rotates, which makes the through hole 111 need to have a large size in the first direction in order to provide a large space for the swing of the second link 12.

[0061] Based on this, in this embodiment, by setting the through hole 111 as an elliptical hole with its longest diameter parallel to the first direction, the through hole 111 can meet the swing space requirements of the second link 12, and the dimensions of the through hole 111 in other directions can be controlled, which is conducive to controlling the dimensions of the first link 11. This is beneficial to controlling the volume and material usage of the first link 11, thereby reducing the material cost and assembly difficulty of the first link 11.

[0062] In some embodiments, the first link 11 is transitionally fitted with the first ring 13. This allows the first link 11 to move relative to the first ring 13 along its own axis when driving the inner blade 23 to rotate, while also ensuring the continuity of the transmission.

[0063] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the air conditioning outlet assembly 2 provided in an exemplary embodiment of this disclosure. Figure 6 This is an exploded view of the internal components of an air conditioning vent assembly 2 provided in an exemplary embodiment of this disclosure. Accordingly, embodiments of this application also provide an air conditioning vent assembly 2. The air conditioning vent assembly 2 includes a frame 21, an outer blade 22, an inner blade 23, and a transmission structure 1 provided in some embodiments of this application. The frame 21 has an air outlet 211. The outer blade 22 is disposed within the air outlet 211 and is rotatably connected to the frame 21 about a second direction. The inner blade 23 is disposed within the air outlet 211 and is located on the side where the outer blade 22 is exposed to air. The inner blade 23 is rotatably connected to the frame 21 about a first direction. A first connecting rod 11 is movably inserted into the inner blade 23 along the first direction. A second connecting rod 12 is slidably connected to the outer blade 22 along the second direction.

[0064] Specifically, at least one end of the first link 11 is movably connected to the inner blade 23 along a first direction. One end of the second link 12 is slidably connected to the outer blade 22 along a second direction.

[0065] It is understood that the first connecting rod 11 is movably inserted into the inner blade 23 along the first direction, so that the first connecting rod 11 can both rotate and move relative to the inner blade 23 around the first direction. Specifically, the first connecting rod 11 is inserted into the inner blade 23 along the first direction, and the first connecting rod 11 and the inner blade 23 are in clearance fit or transition fit.

[0066] In this design, a groove can be provided on one of the second connecting rod 12 and the outer blade 22, and a slider that slides with the groove can be provided on the other to achieve a sliding connection between the two.

[0067] In this embodiment, by employing the transmission structure 1 provided in some embodiments of this application, the influence of adjusting the outlet angle of the outer blade 22 on the transmission of forces within the transmission structure 1 can be reduced. This reduces the degree to which the relative rotation between the outer blade 22 and the inner blade 23 affects each other, which is beneficial for increasing the range of relative rotation angles between the outer blade 22 and the inner blade 23. Thus, the degree of restriction on the relative position of the outer blade 22 and the inner blade 23 can be reduced.

[0068] Please see Figure 6In some embodiments, the air conditioning outlet assembly 2 further includes a rack 24 and a gear 25. The rack 24 is slidably connected to the outer blade 22 along a second direction. The rack 24 is connected to the end of the second connecting rod 12 near the outer blade 22. The gear 25 is rotatably mounted on the outer blade 22 about a first direction. The rack 24 and the gear 25 mesh. In this way, on the one hand, by applying force to the circumferential direction of the gear 25, the torque of the applied force can be increased, thereby reducing the amount of force required to drive the second connecting rod 12 to slide along the second direction, thus improving operability; on the other hand, the rotational movement of the gear 25 can realize the movement of the second connecting rod 12 in the second direction, thereby improving the controllability of the movement stroke of the second connecting rod 12, and thus improving the adjustment accuracy of the rotation angle of the inner blade 23.

[0069] Please see Figure 6 and Figure 7 , Figure 7 This is a schematic diagram illustrating the engagement of the outer blade 22 with the gear 25 and rack 24 according to an exemplary embodiment of this disclosure. In some embodiments, the outer blade 22 has an inner cavity 223 and a first opening 221 and a second opening 222 communicating the inner cavity 223 with the outside. The gear 25 and rack 24 are both disposed in the inner cavity 223. Part of the gear 25 protrudes from the first opening 221. The second connecting rod 12 passes through the second opening 222 and connects to the rack 24. In this way, the gear 25, rack 24, and other components share a portion of the space with the outer blade 22, thereby reducing the impact of the gear 25, rack 24, and other components on the air outlet 211, which helps to increase the actual air outlet area of ​​the air conditioner, thereby improving the air conditioner's air outlet performance.

[0070] Furthermore, embedding the gear 25 within the outer blade 22 also helps to improve the aesthetics of the air conditioning vent assembly 2.

[0071] Please see Figure 6 and Figure 7 In some embodiments, the outer blade 22 is provided with a strip-shaped hole 224. The strip-shaped hole 224 penetrates the inner cavity 223. The direction of the longest diameter of the strip-shaped hole 224 is parallel to a second direction. The air conditioning outlet assembly 2 also includes a first component 26. The first component 26 includes a first nail 261 and a second nail 262 located on both sides of the outer blade 22. The end of the shank of the first nail 261 passes through one side of the strip-shaped hole 224 and is inserted into the rack 24. The end of the shank of the second nail 262 passes through the other side of the strip-shaped hole 224 and is connected to the first nail 261. The first nail 261 and the second nail 262 are rotatably engaged with the rack 24.

[0072] In this way, the rack 24 can roll into contact with the outer blade 22 during movement through the first component 26, thereby reducing the friction between the rack 24 and the outer blade 22 and improving the smoothness of the rack 24's movement.

[0073] It is understandable that the head of the first nail 261 and the head of the second nail 262 screw engage with the outer blade 22 to prevent the first nail 261 and the second nail 262 from moving along their own axial direction.

[0074] Please see Figure 6 In some embodiments, there are multiple first components 26, which are spaced apart along the second direction. This allows for a larger force-bearing area at the mating part between the rack 24 and the outer blade 22, thereby improving the uniformity of force distribution and thus improving the stress and condition.

[0075] Please see Figure 6 In some embodiments, the shank end of the second nail 262 is provided with a threaded hole. The first nail 261 is a screw, and its shank end is threadedly connected to the threaded hole. In this way, the second nail 262 and the first nail 261 can be detachably connected, which helps to improve the ease of assembly and maintainability of the air conditioning vent assembly 2.

[0076] Specifically, the rack 24 is provided with a first mating through hole, the end of the rod of the second nail 262 passes through one end of the strip hole 224 and is inserted into the first mating through hole, the end of the rod of the first nail 261 passes through one end of the strip hole 224 and is inserted into the first mating through hole, and is simultaneously inserted into the threaded hole and threadedly connected to the threaded hole.

[0077] Please see Figure 6 In some embodiments, the air conditioning outlet assembly 2 further includes a second component 27. The second component 27 includes a third pin 271 and a fourth pin 272 located on both sides of the outer blade 22, respectively. The end of the rod of the third pin 271 is inserted into the inner cavity 223 and engages with the gear 25. The end of the rod of the fourth pin 272 is inserted into the inner cavity 223 and connects with the third pin 271. The third pin 271 and the fourth pin 272 are rotatably engaged with the gear 25.

[0078] Specifically, the fourth pin 272 has a threaded hole at the end of its shank. The third pin 271 is a screw, with its shank end threaded into the threaded hole. This improves the operability of installing the gear 25 onto the outer blade 22 and facilitates later maintenance.

[0079] It is understandable that the head of the third nail 271 and the head of the fourth nail 272 screw engage with the outer blade 22 to prevent the third nail 271 and the fourth nail 272 from moving along their own axial direction.

[0080] Please see Figure 8 , Figure 8This is a schematic diagram illustrating the connection between the rack 24 and the second link 12 according to an exemplary embodiment of this disclosure. In some embodiments, a connecting shaft 241 is provided on the side of the rack 24 near the second link 12, and the two ends of the connecting shaft 241 are respectively connected to the rack 24 and the second link 12. This facilitates the improvement of the ease of operation of connecting the rack 24 and the second link 12.

[0081] For example, the connecting shaft 241 and the rack 24 are integrally formed.

[0082] Please see Figure 8 In some embodiments, a U-shaped block 121 is provided at the end of the second connecting rod 12 near the connecting shaft 241. The end of the connecting shaft 241 away from the rack 24 is inserted into the U-shaped block 121 and connected to the U-shaped block 121 by a pin. In this way, the area of ​​the mating surface between the connecting shaft 241 and the second connecting rod 12 can be increased, thereby improving the transmission continuity.

[0083] Please see Figure 6 In some embodiments, gear 25 is an incomplete gear 25, with a portion of its circumferential surface having teeth that mesh with rack 24, and another portion having anti-slip texture. This improves the ease of operation for the user to turn gear 25 and prevents slippage.

[0084] Please see Figure 6 In some embodiments, the air conditioning outlet assembly 2 further includes a third link 28. There are multiple inner blades 23. The multiple inner blades 23 are spaced apart along a second direction. Each inner blade 23 is hinged to the third link 28. The multiple inner blades 23 can improve the uniformity of airflow from the outlet 211, thereby enhancing passenger comfort.

[0085] Accordingly, embodiments of this application also provide a vehicle that includes the aforementioned air conditioning vent assembly 2.

[0086] Among them, vehicles can be gasoline-powered vehicles, natural gas-powered vehicles, or pure electric vehicles, and new energy vehicles can be pure electric vehicles, hybrid vehicles, or range-extended vehicles, etc.

[0087] In this embodiment, by employing the air conditioning outlet assembly 2 provided in some embodiments of this application, the influence of adjusting the air outlet angle of the outer blade 22 on the transmission of forces within the transmission structure 1 can be reduced. This reduces the degree to which the relative rotation between the outer blade 22 and the inner blade 23 affects each other, which is beneficial for increasing the range of relative rotation angles between the outer blade 22 and the inner blade 23. Thus, the degree of restriction on the relative position of the outer blade 22 and the inner blade 23 can be reduced.

[0088] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
