[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0037] Elbow rests provide effective support for pilots' arms when operating the control stick. Due to differences in height, build, and operating habits among pilots, the elbow rest plate needs to be adjustable to meet the specific needs of different pilots. Besides the adjustability, the ease of adjustment also significantly impacts the performance of the elbow rest.
[0038] Based on the actual needs of elbow support devices in applications, in some embodiments of this utility model, referring to Figures 1, 2, 3, and 4, the pilot elbow support device includes:
[0039] Bracket 11;
[0040] The lateral adjustment assembly includes a first motor 21, a lateral transmission unit, a lateral slide rail 12 arranged horizontally on the bracket, and a lateral slider 13 that slides with the lateral slide rail. The first motor 21 drives the lateral slider 13 to move along the lateral slide rail 12 through the lateral transmission unit.
[0041] The vertical adjustment assembly includes a second motor 22, a vertical transmission unit, a vertical slide rail 14 disposed on the horizontal slider in the vertical direction, and a vertical slider 15 that slides in cooperation with the vertical slide rail. The second motor 22 drives the vertical slider 15 to move along the vertical slide rail 14 through the vertical transmission unit.
[0042] Elbow support assembly, which is rotatably connected to vertical slider 15, allowing the elbow support assembly to rotate in the horizontal plane;
[0043] A rotation locking assembly is used to lock the elbow support assembly to restrict its rotation.
[0044] The bracket 11 is used for installation in the aircraft cockpit. The bracket 11 is designed as a hollow frame structure, which can reduce the weight of the bracket while ensuring the structural strength of the bracket. The mounting surface of the bracket is set as an inclined surface that matches the side wall of the cockpit, so that the elbow support assembly is in a horizontal state when the bracket is installed on the side wall of the cockpit.
[0045] The horizontal adjustment component drives the elbow support component to move back and forth, while the vertical adjustment component drives the elbow support component to move up and down, enabling the elbow support component to be adjusted in two degrees of freedom. The motor is used for drive control, making the adjustment operation more convenient.
[0046] At this point, the elbow support assembly's adjustment in two degrees of freedom can meet the pilot's needs to a certain extent. However, the elbow support assembly is usually positioned to extend towards the pilot. Due to different pilot operating habits, the support requirements provided by the elbow support assembly also vary. Based on this need, in this embodiment, the elbow support assembly is configured to rotate in the horizontal plane around the vertical axis connected to the vertical slider. By adding a rotational degree of freedom to the elbow support assembly, its performance is further expanded, better meeting the pilot's personalized needs. Furthermore, through the rotation of the elbow support assembly in the horizontal plane, it is possible to rotate the elbow support assembly to a suitable angle, satisfying the pilot's support needs while also rotating it slightly away from the pilot to avoid potential interference with the pilot's operation in some situations.
[0047] In some embodiments, referring to FIG5, the rotation locking assembly includes a sleeve 31 and a locking rod 32. The sleeve 31 is disposed on the elbow support assembly, and the locking rod 32 is slidably connected to the sleeve 31. A return spring 34 is disposed between the locking rod and the sleeve.
[0048] Multiple locking holes 33 are provided on the vertical rotating shaft 16 that connects the elbow support assembly and the vertical slider. The locking holes 33 are arranged circumferentially on the vertical rotating shaft, and the end of the locking rod 32 can be inserted into the locking hole 33 to lock the elbow support assembly.
[0049] Under the action of the return spring, the locking rod is always pressed tightly into the lock hole, providing a stable lock for the elbow support assembly. When it is necessary to rotate and adjust the elbow support assembly, the locking rod is pulled out of the lock hole. When the locking rod disengages from the lock hole, it releases the lock on the elbow support assembly. After the adjustment is completed, the locking rod is released, and under the action of the return spring, the locking rod is pushed into the corresponding lock hole, locking the elbow support assembly in the current position.
[0050] The keyhole and the end of the lock bar are designed with a matching tapered structure to facilitate the insertion of the lock bar into the keyhole.
[0051] The locking holes are evenly distributed circumferentially along the vertical pivot, allowing the elbow support assembly to rotate within an angle range greater than 180°. Referring to Figure 8, when the elbow support assembly is needed, it can be rotated to a position along the longitudinal direction of the machine body, at which point the elbow support assembly can be retracted.
[0052] In some embodiments, to facilitate unlocking, the rotating locking assembly includes an unlocking handle 35, which is hinged at one end to one end of the locking rod 32 and at another position to the elbow support assembly to form a lever structure, making the unlocking operation easier and less strenuous.
[0053] In some embodiments, the elbow support assembly includes an elbow support bracket 17 and an elbow support plate 18. The elbow support bracket 17 is rotatably connected to a vertical slider 15 at one end via a vertical pivot. The elbow support plate 18 is horizontally disposed on the elbow support bracket 17. A rotation locking component is located on the side facing the nose of the aircraft to facilitate rotational adjustment of the elbow support assembly.
[0054] Specifically, the unlocking end of the unlocking handle extends below the elbow rest and is located within the outline of the elbow rest. By utilizing the structure of the elbow rest and the connection between the unlocking handle and the elbow rest, the unlocking handle is concealed, preventing accidental unlocking by the pilot and improving the reliability of the elbow rest device operation.
[0055] In some embodiments, referring to FIG3, the outer contour of the elbow support plate 18 at the end away from the vertical slider is set as an inclined edge, and the outer contour of this end of the elbow support plate gradually approaches the vertical slider in the direction from the nose to the tail. The inclined outer contour of the elbow support plate can further reduce the possibility of interference between the elbow support plate and the pilot, and can reduce the possibility of interference between the elbow support plate and other structures in various rotation positions, without affecting its support performance.
[0056] Based on this design concept, the outer contour of the elbow support plate 18 away from the vertical slider is connected to the side facing the tail section by a chamfer transition. This chamfer transition structure further optimizes the support surface of the elbow support plate, thereby improving its performance.
[0057] The end of the elbow support plate 18 furthest from the pilot is set as a raised inclined surface, while the part of the elbow support plate closest to the pilot is set as a flat surface, so as to better match the use of the elbow support assembly at various rotation angle positions.
[0058] In some embodiments, referring to Figures 6 and 7, the horizontal transmission unit and the vertical transmission unit include a lead screw 23 and a lead screw nut 24. The lead screw nut 24 is connected to the horizontal slider 13 or the vertical slider 15. The first motor and the second motor drive the corresponding lead screw 23 to rotate. The transmission method using a lead screw and lead screw nut is simple in structure and can improve the transmission accuracy.
[0059] The lead screw is rotatably connected to the bracket and the horizontal slider respectively. Openings are provided on the horizontal and vertical slide rails respectively, so that the horizontal slider and the vertical slider can be connected to the corresponding lead screw nut.
[0060] To facilitate the installation of the first and second motors on the device and their connection with the corresponding transmission units, the first motor 21 is mounted on the bracket 11, and the second motor 22 is mounted on the horizontal slider 13. The lead screws 23 of the horizontal and vertical transmission units are located on the side closest to the horizontal or vertical slider, respectively, and the first and second motors are connected to the lead screws of the horizontal and vertical transmission units via gears 25. This gear transmission forms a reduction mechanism between the motors and the lead screws to improve the control accuracy of the adjustment.
[0061] An adjustment button 26 is located on one side of the bracket to control the rotation of the first and second motors. The button 26 controls the forward and reverse rotation of the first and second motors, enabling reciprocating motion adjustment in the horizontal and vertical directions. The frame structure design of the bracket facilitates the placement of the adjustment buttons and electrical control components.
[0062] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0063] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0064] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
