A sliding grille for automobiles

Abstract

This utility model discloses a sliding grille for automobiles, including a mounting plate with two sets of grilles on it. The two sets of grilles are connected by two sets of linkage structures, each connected to a first rotating shaft and a second rotating shaft. The first and second rotating shafts are connected to a first knob and a second knob, respectively. A long key is provided on the first rotating shaft, and a long groove is provided on the first knob. The first knob engages with the first rotating shaft through the engagement of the long groove and the long key. A short key is provided on the second rotating shaft, corresponding to the long key. This utility model achieves the engagement and disengagement of the long groove and the short and long keys through the lateral sliding of the first knob, thus integrating both independent and linkage adjustment modes into one mechanism. This effectively solves the contradiction between the cumbersome and inaccurate synchronous operation of independent knobs and the inability to adjust integrated knobs separately in traditional solutions.

Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to a sliding grille for automobiles. Background Technology

[0002] The air conditioning vent grille is an important functional component in car interiors, primarily serving to guide airflow and provide a comfortable airflow experience for passengers. To meet different air delivery needs, the air conditioning grille is usually designed with an adjustable angle.

[0003] In existing technologies, automotive air conditioning vents, especially the dual-grille design in the center console serving both the driver and front passenger, typically adjust their tilt angle using an integrated knob that simultaneously drives the left and right grille blade groups to quickly open, close, and tilt the two grilles. However, a significant drawback is its lack of flexibility, failing to meet the personalized needs of the driver and front passenger for different airflow angles.

[0004] Therefore, in the prior art, each of the left and right air conditioning grilles is equipped with an independent adjustment knob, and each knob controls the blade angle of the corresponding grille, thereby realizing independent adjustment of each grille and improving flexibility.

[0005] However, in actual use, the two adjustment knobs are usually located on the sides or below the two grilles, requiring the user's hand to move and search between two relatively far locations, a cumbersome and inconvenient process. Furthermore, when users want to adjust the two grilles to the exact same tilt angle to maintain visual symmetry or achieve a unified airflow pattern, the two knobs are independent and lack a reference point. Users must rely on repeated visual comparison and fine-tuning, a difficult process that makes it hard to guarantee the accuracy and consistency of the grille angle adjustments, often resulting in deviations that affect the product's aesthetics and user experience. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A sliding grille for automobiles includes a mounting plate on which two sets of grilles are mounted. The two sets of grilles are respectively connected to two sets of linkage structures for adjusting the tilt angle of the upper grille plates. The two sets of linkage structures are respectively connected to two first rotating shafts and second rotating shafts for inputting rotational torque. The first rotating shaft and the second rotating shaft are coaxially arranged and respectively connected to a first knob and a second knob. The first knob and the second knob are arranged side by side between the two sets of grilles.

[0008] The first rotating shaft is provided with a long key, which extends along the axial direction of the first rotating shaft. The first knob is provided with a long groove, which engages with the first rotating shaft through the long groove and the long key. The long groove can slide along the length direction of the long key.

[0009] The second rotating shaft is provided with a short key, which is corresponding to the long key. The first knob slides axially through a long groove and engages synchronously with the long key and the short key to drive the first rotating shaft and the second rotating shaft to rotate synchronously.

[0010] As a preferred embodiment of this utility model, the linkage structure includes a groove on the mounting plate located on one side of the grid, a slide plate slidably disposed in the groove, the slide plate having teeth, the teeth meshing with a gear, the gear being coaxially fixedly disposed at the end of the rotating shaft of the grid plate, and the first rotating shaft and the second rotating shaft being coaxially fixedly connected to the rotating shaft of the grid plate.

[0011] As a preferred embodiment of this utility model, a sliding sleeve is coaxially fixedly provided on the first rotating shaft, and the long groove is formed on the inner wall of the sliding sleeve.

[0012] In a preferred embodiment of this utility model, magnetic components are provided on both sides of the first knob, and the magnetic components are used to movably connect with the second knob and the mounting plate.

[0013] As a preferred embodiment of this utility model, the circumferential sides of the first knob and the second knob are provided with friction texture.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention achieves the engagement and disengagement of the long groove and short key / long key by sliding the first knob laterally, thus integrating two modes of independent adjustment and linkage adjustment in one mechanism. This effectively solves the contradiction between the cumbersome and inaccurate synchronous operation of independent knobs and the inability to adjust the integrated knob separately in traditional solutions. It can achieve independent and flexible adjustment of the two side grilles without interference to meet differentiated air supply needs, and can also quickly enter the linkage mode. The rotation of a single knob can achieve precise synchronous and equal angle adjustment of the two grilles, greatly improving the operating efficiency and angle uniformity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4As shown, this utility model provides a sliding grille for automobiles, including a mounting plate 1, two sets of grilles 2, two sets of linkage structures 3, a first rotating shaft 4, a second rotating shaft 5, a first knob 6, and a second knob 7. Specifically, the mounting plate 1 is fixedly installed on the center console or air vent area of ​​the automobile, serving as a support structure for the grilles 2 and related components. Two sets of grilles 2 are symmetrically arranged on the mounting plate 1. Each set of grilles 2 includes multiple parallel-arranged gratings 15, each grating 15 being rotatably mounted on the mounting plate 1 via a rotating shaft. The airflow direction is adjusted by rotating up and down. Each set of grilles 2 is connected to a linkage structure 3 for adjusting the tilt angle of the grating 15. The linkage structure 3 converts the rotational input into a change in the tilt angle of the grating 15 through mechanical transmission. Two sets of linkage structures 3 are respectively connected to the first rotating shaft 4 and the second rotating shaft 5. The first rotating shaft 4 and the second rotating shaft 5 are used to input rotational torque to the linkage structure 3, thereby triggering the movement of the linkage structure 3 to drive the multiple grid plates 15 in the grid 2 to rotate synchronously. The first rotating shaft 4 and the second rotating shaft 5 do not contact each other. They are coaxial plastic or metal shafts, and their extension direction is consistent with the length direction of the mounting plate 1, with their ends facing each other. The ends of the first rotating shaft 4 and the second rotating shaft 5 are respectively connected to the first knob 6 and the second knob 7. The first knob 6 and the second knob 7 are cylindrical or semi-cylindrical operating parts, made of plastic or metal materials, with friction textures 18 on the circumferential side surface. The friction textures 18 are strip-shaped grooves or dot-shaped protrusions evenly distributed along the circumference of the knob, and the material is the same as the knob body. The friction textures 18 increase the friction between the user's fingers and the knob, making the rotation operation more effortless and less prone to slippage. This design, with its parallel arrangement of knobs, allows users to quickly switch knobs or simultaneously adjust two sets of grilles 2 while operating with one hand, significantly improving the intuitiveness and convenience of operation. The first knob 6 and the second knob 7 are arranged side-by-side between the two sets of grilles 2, located in the central area of ​​the mounting plate 1, facilitating one-handed operation and solving the problem of scattered knob positions and inconvenient operation mentioned in the background art. A long key 8 is provided on the first rotating shaft 4. The long key 8 is a rectangular protrusion extending along the axis of the first rotating shaft 4 and is fixedly mounted on the circumferential sidewall of the first rotating shaft 4, allowing it to be integrally formed with the first rotating shaft 4. A long groove 9 is provided on the first knob 6, the shape of which matches the long key 8. The first knob 6 engages with the first rotating shaft 4 through the engagement of the long groove 9 and the long key 8, and the long groove 9 can slide along the length of the long key 8. Through the engagement of the long groove 9 and the long key 8, the first knob 6 and the first rotating shaft 4 form a slidable but non-rotatable connection.

[0025] like Figure 4As shown, a short key 10 is provided on the second rotating shaft 5. The short key 10 is a protrusion similar in shape to the long key 8 but shorter in length. The short key 10 is correspondingly provided to the long key 8, and the short key 10 and the long key 8 are aligned axially. The first knob 6 slides axially through the long groove 9, which engages synchronously with the long key 8 and the short key 10 to drive the first rotating shaft 4 and the second rotating shaft 5 to rotate synchronously. When the user slides the first knob 6 axially, the long groove 9 can simultaneously engage with the long key 8 of the first rotating shaft 4 and the short key 10 of the second rotating shaft 5. At this time, rotating the first knob 6 can drive the first rotating shaft 4 and the second rotating shaft 5 to rotate synchronously through the engagement of the long groove 9 with the long key 8 and the short key 10, thereby adjusting the grid plates 15 of the two sets of grids 2 to the same tilt angle synchronously.

[0026] like Figure 2 As shown, the linkage structure 3 includes a slide groove 11, a slide plate 12, teeth 13, and gears 14. Specifically, the slide groove 11 is formed on the mounting plate 1 and located on one side of the grille 2. The slide plate 12 is slidably disposed in the slide groove 11, and its length is less than the length of the slide groove 11 to ensure smooth sliding within the slide groove 11.

[0027] like Figure 2 As shown, the slide groove 11 has the same shape as the mounting plate 1, and is arc-shaped. The slide plate 12 is arc-shaped and is slidably disposed in the slide groove 11. The slide plate 12 can be limited and slidably disposed in the slide groove 11 by means of a limiting slider and other structures. The length of the slide plate 12 is less than the length of the slide groove 11, so that the slide plate 12 can slide in the length direction of the slide groove 11. The sliding stroke of the slide plate 12 is set to be able to drive the grid plate 15 to rotate at all angles.

[0028] like Figure 2 As shown, the slide plate 12 has teeth 13, which are tooth-like structures arranged along the length (outline) of the slide plate 12, similar to a rack. The teeth 13 mesh with gears 14, which are small circular gears fixedly mounted at the end of the rotating shaft of the grid plate 15. The rotating shaft of the grid plate 15 passes through the grid plate 15 and is fixed at its center, allowing the grid plate 15 to rotate around the rotating shaft. The first rotating shaft 4 and the second rotating shaft 5 are respectively coaxially fixedly connected to the rotating shaft of one grid plate 15 on the corresponding grid 2. When the user rotates the first rotating shaft 4 or the second rotating shaft 5, it can directly drive one grid plate 15 to rotate. The gear 14 at the end of this grid plate 15 will drive the slide plate 12 to slide, and then drive the other grid plates 15 to rotate through the remaining gears 14, thereby achieving synchronous tilt angle adjustment of the grid plates 15 of the entire grid 2.

[0029] Furthermore, such as Figure 4As shown, to optimize the connection between the first knob 6 and the first rotating shaft 4, a sliding sleeve 16 is coaxially fixed in the middle of the first knob 6, and the elongated groove 9 is formed on the inner wall of the sliding sleeve 16. The sliding sleeve 16 is a cylindrical sleeve, which is coaxially fixed to the middle of the first knob 6 by welding or interference fit. The elongated groove 9 is directly formed on the inner wall of the sliding sleeve 16, replacing the elongated groove 9 on the inner wall of the first knob 6. The shape and size of the elongated groove 9 are the same as those of the long key 8, ensuring that the first knob 6 engages with the long key 8 of the first rotating shaft 4 through the elongated groove 9, and can slide axially to engage with the short key 10 of the second rotating shaft 5.

[0030] In practical use, the first knob 6 slides to engage the long groove 9 with the short key 10 after the two knobs are used individually. Therefore, the position of the long groove 9 and the position of the short key 10 may not correspond. At this time, the first knob 6 and the second knob 7 can be rolled simultaneously to one side (up or down) to make them roll into place (this operation is very convenient because the first knob 6 and the second knob 7 are set side by side in the middle of the mounting plate 1). At this time, the long groove 9 corresponds to the position of the short key 10, which allows the first knob 6 to slide and engage with the short key 10.

[0031] The sliding sleeve 16 improves the stability and durability of the connection between the first rotating shaft 4 and the first knob 6, reduces the technological difficulty of directly machining the long groove 9 on the inner wall of the first knob 6, and facilitates maintenance and replacement. The material of the sliding sleeve 16 can be the same metal material as the first rotating shaft 4 to ensure mechanical strength during long-term use.

[0032] like Figure 4 As shown, further, to improve stability and ensure the first knob 6 remains stable in its normal position without accidental sliding (sliding along the first rotating shaft 4), magnetic suction components 17 are provided on both sides of the first knob 6. These magnetic suction components 17 are used to movably connect the first knob 6 to the second knobs 7 on either side and the mounting plate 1, making it more stable and preventing displacement whether used alone or after linear sliding. The magnetic suction components 17 can be embedded in the end face of the sliding sleeve 16 and the side of the first knob 6 to connect with the second knobs 7 and the mounting plate 1 respectively.

[0033] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
