Description

Technical Field

[0001] The utility model relates to the technical field of flight simulation training in a crew simulator, in particular to an electric drive mechanism of an elevator adjustment piece. Background Art

[0002] Flight attendant simulators primarily focus on flight simulation training / demonstration construction, advanced simulation / experimental environment development, and the design and integration of dynamic cabin systems for flight attendants. They are primarily used to train cabin crew professional skills. The elevator control system is one of the three primary flight controls on an aircraft, and the elevator tab control system is a secondary flight control used to balance the aircraft, reduce pilot fatigue, and alleviate control forces on the control column during takeoff and landing.

[0003] The elevator trim tab control system transmits control signals to the corresponding mechanical actuators to control the trim tab deflection. Current flight simulators cannot accurately simulate the feeling of a pilot manipulating the trim wheel in a real aircraft. Furthermore, their complex design reduces the effectiveness of simulated flight training for personnel. Utility Model Content

[0004] In view of this, an object of the present invention is to provide an electric drive mechanism for an elevator trim plate, which has a simple structure and is easy to install and operate.

[0005] To achieve the above purpose, the present invention adopts the following contents:

[0006] The utility model provides an electric drive mechanism for an elevator trim piece, which comprises:

[0007] Two supports are symmetrically arranged on both sides, and a rotating shaft is arranged between the two supports for common rotation, and the ends of the rotating shaft are both connected outwardly to a balancing wheel;

[0008] Two swing plates are symmetrically arranged between the support and the trim wheel, and a synchronization shaft is connected between the lower parts of the two swing plates. The synchronization shaft is rotatably arranged between the two supports, and the upper parts of the swing plates can swing synchronously with the rotation of the trim wheel;

[0009] The top of the support is provided with a marking plate with a prompt scale, and the head end of the swing plate is provided with a pointer located above the marking plate, and the pointer can rotate relative to the marking plate;

[0010] A potentiometer is fixedly provided at the bottom of one of the supports, and an aviation interface electrically connected to the potentiometer is provided at the bottom of the other support. The output end of the potentiometer is externally connected to a pinion, and the pinion is meshed with a main gear fixed on the rotating shaft.

[0011] According to the electric drive mechanism for an elevator trim plate provided by the present invention, the inner wall of the trim wheel has a protruding boss portion, the boss portion having a concave spiral groove formed in its surface. A pin is protruding from the middle portion of the inner wall of the swing plate, and the pin is located in the groove. When a flight trainer manually rotates the trim wheel, the pin is forced to move along a portion of the groove, forcing the swing plate to rotate about its lower connection point, causing the swing plate to swing back and forth relative to the marking plate.

[0012] According to the electric drive mechanism for an elevator trim tab provided by the present invention, a compression spring is movably mounted on the rotating shaft. One end of the compression spring is connected to one of the supports, and the other end is secured to the rotating shaft via a lock nut. Thus, when a flight trainee manually rotates the trim wheel, the rotating shaft will also rotate synchronously. This rotation of the rotating shaft causes the compression spring to twist, thereby creating a damping effect on the rotating shaft, allowing the flight trainee to simulate a realistic force sensation during operation.

[0013] According to the electric drive mechanism for an elevator trim tab provided by the present invention, the upper surface of the marking plate is arcuate, and a transparent plate is disposed above the marking plate. The pointer is movable between the transparent plate and the marking plate. Because the pointer's motion path is arcuate, the upper surface of the marking plate is also designed to have an arcuate structure of the same arc. The corresponding position to which the pointer rotates indicates the current control instruction.

[0014] According to the electric drive mechanism for an elevator trim plate provided by the present invention, a plurality of anti-slip protrusions are arranged in an array at intervals on the outer periphery of the trim wheel. The anti-slip protrusions ensure that flight trainees can maintain a stable grip on the trim wheel while manually rotating it, preventing slippage.

[0015] According to the electric drive mechanism of the elevator trim plate provided by the present invention, the two supports are fixedly connected via two fixed shafts, and the two fixed shafts are used to ensure the connection stability between the two supports.

[0016] Compared with the prior art, the present invention has the following technical effects: the present invention has a simple structure and a reasonable design; the driver controls the rotating shaft to rotate clockwise or counterclockwise by operating the trim wheel, thereby realizing the output action of the potentiometer under the cooperation of the main gear and the auxiliary gear, and the driver's operating behavior is converted into a corresponding electrical signal through the electronic sensor, that is, the potentiometer and outputted to the corresponding mechanical drive device, and the elevator adjustment plate is controlled by the external mechanical drive device, which has the characteristics of fast response time and simple and fast operation method; and the driver's operating behavior can also be displayed through the cooperation of the swing plate, the pointer, and the marking plate, so that the operating instructions can be observed, and the current operating status is convenient to check.

DETAILED DESCRIPTION

[0021] 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.

[0022] 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.

[0023] See also Figure 1 and Figure 2The present invention provides an electric drive mechanism for an elevator trim plate, which is used for simulating the operation of an elevator trim plate in a crew simulator. The mechanism mainly comprises two symmetrically arranged supports 1, a rotating shaft 2 being rotatably arranged between the two supports 1, and a circular trim wheel 3 being connected outwardly at each end of the rotating shaft 2; two symmetrically arranged swing plates 4 respectively located between the supports 1 and the trim wheel 3, a synchronous shaft 5 being connected between the lower portions of the two swing plates 4, and the synchronous shaft 5 realizing the synchronous movement of the two swing plates 4. The synchronous shaft 5 is rotatably arranged between the two supports 1, and the upper portion of the swing plate 4 can swing synchronously with the rotation of the trim wheel 3, that is, the swing plate can swing with its lower connection point as the rotation center.

[0024] Among them, a marking plate 6 with a prompt scale (not shown) is provided at the top of the support 1, and a pointer 41 is provided at the head end of the swing plate 4 above the marking plate 6. During the swinging of the swing plate 4, the pointer 41 can rotate relative to the marking plate; a potentiometer 7 is fixedly provided at the lower part of one of the supports 1, and an aviation interface 8 electrically connected to the potentiometer 7 is provided at the lower part of the other support 1. The output end of the potentiometer 7 is externally connected to a sub-gear 71, and the sub-gear 71 is meshed with a main gear 21 fixed on the rotating shaft 2.

[0025] During use, the pilot controls the rotating shaft to rotate clockwise or counterclockwise by operating the trim wheel, thereby realizing the corresponding output action of the potentiometer under the cooperation of the main gear and the auxiliary gear. The pilot's control behavior is converted into a corresponding electrical signal through the electronic sensor, that is, the potentiometer, and outputted to the corresponding mechanical drive device. The elevator adjustment plate is controlled by the external mechanical drive device, which has the characteristics of fast response time and simple and fast operation. Moreover, the pilot's control behavior can also be displayed through the cooperation of the swing plate, pointer, and marking plate, so that the control instructions can be observed, which is convenient for checking the current control situation. For example, according to the relative position of the pointer and the prompt scale on the marking plate, it is possible to judge what action is being performed at this time.

[0026] Specifically, the inner wall of the trim wheel 3 has a protruding boss 31, with a spiral groove 32 recessed in the surface of the boss 31. A pin 42 protrudes from the middle of the inner wall of the swing plate 4, and the pin 42 fits neatly within the groove 32. When the flight trainer manually turns the trim wheel, the wheel rotates, and the groove also rotates. This forces the pin to move along part of the groove, which then forces the swing plate to rotate around its lower connection point, thereby causing the swing plate to swing back and forth relative to the marking plate.

[0027] Specifically, a compression spring 22 is movably mounted on the rotating shaft 2. One end of the compression spring 22 is connected to one of the supports 1, and the other end of the compression spring 22 is secured to the rotating shaft 2 via a lock nut 23. Thus, when a flight trainee manually turns the trim wheel, the rotating shaft will also rotate synchronously. This rotation of the rotating shaft causes the compression spring on it to twist, thereby creating a certain damping effect on the rotating shaft, allowing the flight trainee to simulate a realistic force sensation during operation.

[0028] Specifically, the upper surface of the marking plate 6 is curved, and a curved transparent plate 61, such as glass, is disposed above the marking plate 6 for protection. The pointer 41 can move between the transparent plate 61 and the marking plate 6. The pointer's movement path is curved, so the upper surface of the marking plate is also designed to have an arc-shaped structure of the same curvature. The corresponding position of the pointer's rotation indicates the current operation instruction.

[0029] Specifically, a plurality of spaced anti-skid protrusions 33 are arranged in an array on the periphery of the trim wheel 3. In this way, the anti-skid protrusions are used to ensure that the flight training personnel can stably grasp the trim wheel during manual rotation of the trim wheel to avoid hand slippage.

[0030] Specifically, the two supports 1 are fixedly connected via two fixed shafts 9. The two fixed shafts are used to ensure the connection stability between the two supports.

[0031] 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.
