[0023] This utility model provides an aviation air outlet grille. The aviation air outlet grille has a simple structure, high reliability, and is not affected by factors such as power outages. It is particularly suitable for aviation environments with stringent requirements for weight and reliability.

[0024] The following is combined with Figures 1-5 The technical solution provided by this utility model will be described in more detail.

[0025] See Figures 1-5As shown, the aviation air outlet grille provided by this utility model includes a panel frame 1, horizontal grille pieces 2, vertical grille pieces 3, a first drive assembly, and a second drive assembly. The panel frame 1 is located at the air outlet, and the horizontal grille pieces 2 and vertical grille pieces 3 are arranged along the airflow direction. All horizontal grille pieces 2 and all vertical grille pieces 3 are rotatably connected to the panel frame 1, and the horizontal grille pieces 2 and vertical grille pieces 3 are arranged perpendicular to each other. The first drive assembly is driven by the horizontal grille pieces 2 and is used to drive all horizontal grille pieces 2 to rotate synchronously. The second drive assembly is driven by the vertical grille pieces 3 and is used to drive all vertical grille pieces 3 to rotate synchronously.

[0026] The panel frame 1 is typically made of lightweight, high-strength engineering plastics or aerospace-grade aluminum alloy, manufactured through injection molding or precision machining. It has a roughly rectangular frame structure that not only defines the air outlet channel but also provides an installation reference for all other components. All horizontal grille plates 2 and vertical grille plates 3 are positioned within the channels defined by the panel frame 1.

[0027] See Figures 1-5 As shown, each transverse grid plate 2 has a pivot at both ends, which is rotatably mounted in shaft holes or bearing seats on two opposite inner sidewalls of the panel frame 1, allowing all transverse grid plates 2 to rotate around their own horizontal axis. Correspondingly, each longitudinal grid plate 3 has a pivot at both ends, rotatably mounted on two other opposite inner sidewalls of the panel frame 1, allowing all longitudinal grid plates 3 to rotate around their own vertical axis. With this arrangement, the rotation axes of the transverse grid plates 2 and the longitudinal grid plates 3 intersect each other (in this preferred embodiment, they are perpendicular), thus forming the basis for two-dimensional adjustment of the airflow. In the airflow direction, one set of grid plates is typically arranged in front of or behind another set of grid plates. For example, the longitudinal grid plates 3 can be arranged upstream of the airflow, while the transverse grid plates 2 can be arranged downstream of the airflow.

[0028] To achieve synchronous control of a group of grid plates, this application embodiment employs a linkage transmission mode. See [link to relevant documentation]. Figures 1-5 As shown, among the multiple transverse grid plates 2, one is selected as the active transverse grid plate 21, and the rest are selected as the passive transverse grid plates 22. Similarly, among the multiple longitudinal grid plates 3, one is selected as the active longitudinal grid plate 31, and the rest are selected as the passive longitudinal grid plates 32.

[0029] The primary purpose of the first drive assembly is to provide a certain mechanical gain to make operation easier when adjusting the transverse grille 2, while achieving more precise angle control through the precise meshing of gears. As an optional implementation, see [link to implementation details]. Figures 1-4As shown, the first drive assembly includes an active tooth 41, a driven tooth 42, and a drive shaft 43. The active tooth 41 and the driven tooth 42 are rotatably connected to the outside of the panel frame 1. The active tooth 41 and the driven tooth 42 mesh with each other. The driven tooth 42 is fixedly connected to the drive shaft 43. The drive shaft 43 is fixedly connected to the active transverse grid plate 21. The axis of the drive shaft 43 is located next to the axis of the driven tooth 42. When the active tooth 41 rotates under the action of external force, the driven tooth 42 and the drive shaft 43 can drive the active transverse grid plate 21 to rotate.

[0030] See Figure 1 and Figure 3 As shown, a lever 44 is fixed on the active gear 41. The lever 44 extends outside the panel frame 1 and is used to be turned by external force.

[0031] See Figure 1 and Figure 3 As shown, the lever 44 is located outside the panel frame 1. It is ergonomically shaped as a flat paddle 5 or a rod with finger grooves, and its surface can be textured with anti-slip material to improve the operating feel. The base of the lever 44 is fixedly connected to the axis of the drive gear 41. The two can be integrally formed or fixedly connected by a key, pin, or screw.

[0032] When the user moves lever 44, the driving gear 41 rotates synchronously. Both the driving gear 41 and the driven gear 42 are standard spur gears. As an optional implementation, see [link to implementation details]. Figure 2 As shown, a baffle frame 8 is fixed on the outer side of the panel frame 1. The driving gear 41 and the driven gear 42 are rotatably connected between the panel frame 1 and the baffle frame 8. The baffle frame 8 cooperates with the panel frame 1 to play a protective and positioning role.

[0033] See Figure 3 and Figure 4 As shown, the driving gear 41 and the driven gear 42 mesh with each other to form a single-stage reduction transmission. The axis of the driven gear 42 is fixedly connected to one end of the drive shaft 43. The drive shaft 43 passes through the panel frame 1, and its other end extends into the interior of the panel frame 1 and is fixedly connected to the aforementioned driving transverse grid plate 21. This fixed connection can be achieved by machining a non-circular cross-section (such as a square or D-shape) at the end of the drive shaft 43 and engaging it with a non-circular hole corresponding to the center of the driving transverse grid plate 21 to transmit torque.

[0034] To transmit the rotation of the active transverse grid plate 21 to all the driven transverse grid plates 22, this embodiment also includes a first tie rod 6. As an optional implementation, see [link to implementation details]. Figures 2-4 As shown, the transverse grid plate 2 includes an active transverse grid plate 21 and a driven transverse grid plate 22, wherein: the first drive assembly is drivenly connected to the active transverse grid plate 21, and a first tie rod 6 is hinged to one end of the active transverse grid plate 21 and the driven transverse grid plate 22. (See also...) Figure 6 As shown, the first tie rod 6 is offset from the hinge axis 45 of the active transverse grid plate 21, which is set to be offset from the rotation axis of the corresponding active transverse grid plate 21. The first tie rod 6 is also offset from the hinge axis 45 of the driven transverse grid plate 22, which is set to be offset from the rotation axis of the corresponding driven transverse grid plate 22. Under the drive of the active transverse grid plate 21, the first tie rod 6 drives all the driven transverse grid plates 22 to rotate synchronously.

[0035] See Figures 2-4 As shown, the first tie rod 6 is a slender rigid rod, the length of which is approximately equal to the width of the grid. On the active transverse grid plate 21 and each driven transverse grid plate 22, a connection point (e.g., a small pin or hinge hole) is provided at the same position offset from its axis of rotation. The first tie rod 6 is movably hinged to all these connection points sequentially through the corresponding holes, thereby achieving synchronous rotation of the active transverse grid plate 21 and all driven transverse grid plates 22.

[0036] As an optional implementation, see Figure 3 As shown, a limiting hole 11 is provided on the side wall of the panel frame 1, and the drive shaft 43 passes through the limiting hole 11. The limiting hole 11 is an arc-shaped hole with the axis of the driven tooth 42 as the center.

[0037] The drive shaft 43 rotates along the limiting hole 11. The two ends of the limiting hole 11 restrict the rotation angle of the active transverse grid plate 21, thereby limiting the air guiding angle and making it easier to control the corresponding air guiding direction.

[0038] As an optional implementation, see Figure 1 and Figure 5 As shown, the longitudinal grid plate 3 includes an active longitudinal grid plate 31 and a driven longitudinal grid plate 32. The second drive assembly is connected to the active longitudinal grid plate 31. A second pull rod 7 is fixed at one end of the active longitudinal grid plate 31 and the driven longitudinal grid plate 32. The second pull rod 7 drives all the driven longitudinal grid plates 32 to rotate synchronously under the drive of the active longitudinal grid plate 31.

[0039] The second tie rod 7 is a rigid rod that connects the active longitudinal grid plate 31 and all the driven longitudinal grid plates 32 by means of a movable hinge. The connection points are also set at the same position on each longitudinal grid plate 3, offset from its axis of rotation.

[0040] See Figure 5The second drive assembly is a directly actuated mechanism designed to enable quick and intuitive adjustment of the longitudinal grid strip 3. In this embodiment, the second drive assembly includes a lever 5, which is fixedly connected to the active longitudinal grid strip 31. A portion of the lever 5 extends outside the panel frame 1 for external actuation. The lever 5 can be directly fixedly connected to the active longitudinal grid strip 31, for example, by integral injection molding or by bonding, snap-fitting, or other methods.

[0041] See Figure 1 and Figure 5 As shown, a portion of the paddle 5 serves as an operating handle, extending from a gap in the side or front of the panel frame 1 and exposed to the outside for direct finger operation by the user. The outer side of the paddle 5, i.e., the position of the operating handle, is provided with a concave-convex structure 51 to increase friction.

[0042] As an optional implementation, see Figure 1 As shown, mounting holes 9 are provided at the corners of the panel frame 1, and locking members pass through the mounting holes 9 to fix the panel frame 1 at the air outlet position; a marking area 10 is provided on the panel frame 1.

[0043] The working process of this embodiment is as follows: When it is necessary to adjust the horizontal direction of the airflow, as shown in the reference... Figures 1-5 As shown, the user applies force to lever 44, causing it to rotate around its axis by an angle. The rotation of lever 44 drives the active gear 41 to rotate synchronously. Since the active gear 41 meshes with the driven gear 42, the rotation of the active gear 41 drives the driven gear 42 to rotate. The rotation of the driven gear 42 is then transmitted through drive shaft 43 to the active transverse grille 21 inside the panel frame 1, causing it to rotate around its horizontal axis. When the active transverse grille 21 rotates, its connection points generate an arc displacement. This displacement is transmitted through the first pull rod 6 to the corresponding connection points of all driven transverse grilles 22, thus forcing all driven transverse grilles 22 to rotate synchronously around their respective axes by the same angle. Ultimately, the deflection angles of all transverse grilles 2 remain consistent, collectively changing the horizontal direction of the airflow and achieving smooth, effortless, and precise horizontal wind direction adjustment.

[0044] When it is necessary to adjust the vertical direction of the airflow, as shown in the reference... Figures 1-5 As shown, the user directly flicks the protruding lever 5 with their finger. Since lever 5 is rigidly fixed to the active longitudinal grille 31, the movement of lever 5 directly causes the active longitudinal grille 31 to rotate synchronously around its vertical axis. The rotation of the active longitudinal grille 31, through the linkage of the second lever 7, causes all the driven longitudinal grilles 32 to rotate synchronously by the same angle. Ultimately, the deflection angles of all the longitudinal grilles 3 remain consistent, collectively changing the vertical direction of the airflow and achieving rapid and intuitive vertical wind direction adjustment.

[0045] The above structure employs a gear mechanism with a transmission ratio for horizontal adjustment (which typically involves a larger adjustment range or requires more precise control), while a direct actuation mechanism is used for vertical adjustment (which typically involves a higher adjustment frequency or requires a rapid response). These two mechanisms operate independently without interference, thus balancing precision, labor-saving, speed, and intuitiveness. Furthermore, the purely mechanical structure ensures high reliability and lightweight design, making it particularly suitable for aerospace environments.
