[0029] The present invention will be described in more detail below with reference to the accompanying drawings showing embodiments of the present invention. However, the present invention may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are set forth in order to achieve a full and complete disclosure and to enable those skilled in the art to fully understand the scope of the present invention. In these drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity.

[0030] As attached Figure 1 The present invention provides an aircraft handwheel simulation device, including a three-layer support platform 5, a handle 1, an actuator, and a sensor. Each two adjacent layers of the support platform 5 are supported and connected by four struts to form four execution areas. The handle 1 is arranged on the first-layer execution area, passing through and perpendicular to the first support platform 5; the actuator is fixedly connected to the handle 1, and is fixedly connected to the sensor through the support platform 5. The actuator includes a rotating actuator and a pressing actuator. Rotating the handle 1 triggers the movement of the rotating actuator and transmits the signal to the first sensor 12. The first sensor 12 converts the mechanical signal into a rotating electronic signal. Similarly, the pressing actuator directly transmits the pressing signal to the second sensor, thereby triggering the second sensor to send a pressing electronic signal.

[0031] The principle of the present invention is simple. It transmits mechanical signals through the force transmission method of the central axis and drives the sensor to send out electronic signals. Compared with the gear transmission structure of the prior art, it has less energy loss, is easy to operate, and has a strong hand feel for the operator. The damage rate of components is low, and the degree of fit between components is high. In addition, the execution area formed by the supporting platform perfectly matches the pressing stroke of the pressing execution part, has a good pressing feel, and has a high space utilization rate. The perfect combination of pressing and rotation on the handle is convenient for the operator to use and has a strong sense of experience.

[0032] In this embodiment, the rotation execution unit includes a central shaft 6 , one end of which is connected to the handle 1 , and the other end of which is connected to the sensor 12 , so as to directly transmit the mechanical signal of the rotation of the handle 1 to the sensor 12 .

[0033] In this embodiment, the rotary actuator further includes a return spring 10, and the pressing actuator further includes a reset spring 3. When the actuator moves, the return spring 10 or the reset spring 3 moves. When the external force is removed, the return spring 10 or the reset spring 3 will drive the actuator to reset. One displacement plus one reset is a complete movement.

[0034] In this embodiment, the rotary actuator also includes a connecting rod 7, a rotating block 9, and a clamping plate 8. The connecting rod 7 is horizontally arranged on the upper part of the bottom support platform 5, one end of which is fixedly connected to the central axis 6, and the other end is fixedly connected to the rotating block 9 arranged at the lower part of the bottom support platform 5; the clamping plate 8 is horizontally arranged at the lower part of the bottom support platform 5, one end of which is in contact with the rotating block 9, and the other end is fixedly connected to the bottom support platform 5, and the return spring 10 is arranged in the middle of the clamping plate 8; the handle 1 drives the central axis 6 to rotate, thereby driving the connecting rod 7 to rotate, thereby driving the rotating block 9 to rotate, and then driving the clamping plate 8 to move, so that the return spring 10 is stretched. When the external force of the handle 1 is removed, the return spring 10 is reset and drives the above-mentioned actuator to reset.

[0035] In this embodiment, the pressing execution part includes a pressing cap 2 and a button 4. The pressing cap 2 is fixed inside the handle 1 and sleeved outside the central axis 6 by bolts, and can move axially relative to the central axis 6 for a certain distance, and the certain distance is the pressing stroke. The button 4 is arranged on the middle support platform 5, and there is a gap between the upper surface and the lower surface of the pressing cap 2, and the gap is smaller than the pressing stroke. Under normal circumstances, the pressing cap 2 is arranged at the upper part of the pressing stroke relative to the central axis 6. After the external force is applied, the pressing cap 2 is pressed and moves to the lower part of the pressing stroke relative to the central axis 6. Since the gap between the pressing cap 2 and the button 4 is smaller than the pressing stroke, the pressing cap 2 will contact the button 4 and press the button 4, thereby triggering the second sensor inside the button 4 and generating an electronic signal. At the same time, the reset spring 3 connected to the bottom surface of the pressing cap 2 and the second support platform 5 is compressed; after the external force is removed, the reset spring 3 is reset and drives the pressing cap 2 back to the upper part of the pressing stroke relative to the central axis 6. At this time, a pressing cycle is completed.

[0036] In this embodiment, two small holes are arranged on the upper side of the pressing cap 2; the bolt passes through the two small holes and the central axis 6, and the two ends are respectively fixedly connected to the handle 1, and the aperture of the small hole is the pressing stroke (the bolt diameter is ignored); one end of the return spring 3 is connected to the pressing cap 2, and the other end is connected to the middle support platform 5; under normal circumstances, the pressing cap 2 is arranged at the upper part of the small hole. After the external force is applied, the pressing cap 2 is pressed down and runs to the lower part of the small hole. Since the gap between the pressing cap 2 and the button 4 is smaller than the pressing stroke, the pressing cap 2 will contact the button 4 and press the button 4, thereby triggering the second sensor inside the button 4 to generate an electronic signal. At the same time, the return spring 3 connected to the bottom surface of the pressing cap 2 and the second support platform 5 is compressed; after the external force is removed, the return spring 3 is reset and drives the pressing cap 2 back to the upper part of the pressing stroke relative to the central axis 6. At this time, a pressing cycle is completed.

[0037] In this embodiment, a scale nozzle is provided on the handle 1 , and the scale nozzle points perpendicular to the connecting rod 7 , and is used to calibrate the displacement stroke of the handle 1 , which is convenient for the operator to observe.

[0038] In this embodiment, the handle 1 is designed and manufactured in a 1:1 ratio with the hand wheel of a real aircraft, and its surface color, shape and size are consistent with the hand wheel of a real aircraft, providing the most realistic feeling for the simulation personnel, which is conducive to cultivating their real operating feeling.

[0039] Because those skilled in the art will appreciate that the present invention can be implemented in many other specific forms without departing from its own spirit or scope. Although the embodiments of the present invention have been described, it should be understood that the present invention should not be limited to these embodiments, and those skilled in the art can make changes and modifications within the spirit and scope of the present invention as defined by the appended claims.
