Description

Technical Field

[0001] The utility model relates to the technical field of flight simulation training in a crew simulator, in particular to a simulated aircraft steering wheel control linkage mechanism. Background Art

[0002] The cabin crew simulator primarily involves the construction of flight simulation training / demonstrations, the development of advanced simulation / experimental environments, and the design and integration of dynamic cabin systems for flight attendants. It is primarily used to train cabin crew professional skills. The control panel system, one of the aircraft's three primary flight control systems, is a key component of the flight simulation training platform, and its performance directly determines the quality of pilot training.

[0003] Currently, most aircraft cockpits are operated by two people with a steering wheel. The real aircraft control structure is complex and large in size, while the cabin crew simulator equipment compartment has a small space and cannot use the real aircraft control structure. The current simulated steering wheel control device has the problems of large size and complex operation. In addition, the dynamic simulation during training simulation is not realistic enough, making it difficult to effectively reproduce the real state of the aircraft during flight.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive and should not limit the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] See also Figure 1 and Figure 2 The present invention provides a simulated aircraft steering wheel linkage mechanism, which is used for simulating flight steering and pitch adjustment in a crew simulator. The mechanism mainly includes two sets of steering wheel mechanisms, each of which includes a steering column 1, a steering wheel 2, a rotating shaft 3, a steering mechanism 4, and a linkage mechanism 5. The linkage mechanism 5 is located in the middle of the two steering wheel mechanisms.

[0022] The lower end of the vertically mounted driving column 1 is pivotally connected to a fixed bracket 9, and the head end of the driving column 1 is designed to be bent. The rotating shaft 3 is rotatably arranged in the hollow interior of the driving column 1 through a bearing, and is mainly arranged in the vertical part of the driving column. The steering wheel 2 is also rotatably connected to the driving column through a bearing, and it and the rotating shaft 3 are transmitted through a two-way universal joint (standard part) 31. The rotating shaft 3 and the steering mechanism 4 are also connected through a universal joint (standard part) 32. The steering mechanisms 4 in the two sets of steering wheel control mechanisms are synchronized through the intermediate linkage mechanism 5. In this way, when the driver rotates the steering wheel, the steering wheel transmits the rotational force to the rotating shaft through the two-way universal joint, causing the rotating shaft to rotate accordingly, thereby driving the steering mechanism to swing left and right by the rotating shaft, and the steering mechanism then controls the steering mechanism in another set of steering wheel control mechanisms to move synchronously through the linkage mechanism.

[0023] The vehicle further includes a pitch operating mechanism 6, which includes a curved portion 11 provided at the lower end of the steering column 1, a linkage shaft 62 rotatably provided between a pair of supports 61, and a pair of first rocker arms 63 provided on the linkage shaft 62. A first connecting rod 64 is pivotally connected between the curved portion 11 and the first rocker arms 63. The linkage shaft 62 is arranged horizontally and perpendicular to the plane of the steering column 1.

[0024] The linkage mechanism 5 and at least one first rocker arm 63 are each pivotally connected to a feel simulation mechanism 7 for simulating the steering feel and the pitching control feel respectively.

[0025] During actual flight training, when it is necessary to simulate steering operations, the control wheel can be turned left or right. At this time, the control wheel drives the steering mechanism to rotate synchronously through the rotating shaft, and the left and right control wheels are synchronized through a linkage mechanism. During the rotation of the linkage mechanism, the hand-feel simulation mechanism can simulate the resistance feeling during the steering process, and the simulation degree is relatively high; when it is necessary to simulate pitch operations, the control wheel can be pushed forward or pulled back to tilt the control column forward or backward. At this time, the inflection portion will push back or pull forward the first rocker arm, causing the linkage shaft to rotate clockwise or counterclockwise. During the rotation of the linkage shaft, the hand-feel simulation mechanism can simulate the resistance feeling during the pitch angle adjustment process, and the simulation degree is relatively high.

[0026] It should be noted that the steering mechanism 4 includes a steering shaft 41 rotatably mounted within a fixed bracket 9. The steering shaft 41 is connected to the rotating shaft 3 via a universal joint 32. A horizontal second rocker arm 42 is provided at the lower end of the steering shaft 41. A horizontal second connecting rod 54 is pivotally connected between the second rocker arm 42 and the linkage mechanism 5. During operation, the steering wheel drives the rotating shaft clockwise or counterclockwise via the bidirectional universal joint. The rotating shaft then drives the rotating mechanism to swing left or right via the universal joint, thereby causing the second connecting rod to pull left or push right.

[0027] Based on the above scheme, the linkage mechanism 5 includes a vertical shaft 52 rotatably disposed between a pair of bearing blocks 51. A horizontal third rocker arm 53 is mounted on the vertical shaft 52. A second connecting rod 54 is pivotally connected between the third rocker arm 53 and the two second rocker arms 42. Thus, when the second rocker arm in one of the steering wheel control mechanisms drives the second connecting rod to move left or right, the second connecting rod also forces the vertical shaft to rotate accordingly through the third rocker arm. The left-right swinging third rocker arm then controls the other steering wheel control mechanism to perform the same movement through the other second connecting rod, thus achieving synchronous linkage of the two steering wheel control mechanisms.

[0028] Based on the above solution, the feel simulation mechanism 7 in this embodiment includes an induction motor 71, a fourth rocker arm 72 disposed at the output end of the induction motor 71, the fourth rocker arm 72 pivotally connected to a third connecting rod 73, the other end of the third connecting rod 73 pivotally connected to a fifth rocker arm 55, and the fifth rocker arm 55 is fixed to the vertical shaft 52. The induction motor is controlled to simulate the resistance during the rotation of the vertical shaft or the linkage shaft, and the force feedback from the steering operation or pitch angle adjustment operation is sensed, thereby simulating a realistic feel.

[0029] It should be noted that a counterweight block 8 can also be provided on the linkage shaft 62 to enhance the sense of gravity of the linkage shaft during pitch operation, thereby improving the dynamic simulation realism of the control linkage mechanism and effectively reproducing the real state of pitch adjustment during aircraft flight.

[0030] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. Other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
