Abstract
Description
Technical Field
[0001] The utility model relates to the field of flight simulators, in particular to an emergency feathering switch device for a flight simulator engine. Background Art
[0002] As the main equipment for pilot training, accurate motion simulation and real force feedback are the key to simulated flight in flight simulators. Compared with the emergency feathering switch device of the real engine, the existing flight simulator engine emergency feathering switch device omits hydraulic pipeline control for economic reasons and is controlled by potentiometer instead. The disadvantages of potentiometer control are: 1. There is a difference in the sense of control force with the real engine emergency feathering switch device, because the damping force of hydraulic pipeline control is greater than that of potentiometer control; 2. There is a difference in appearance with the real engine emergency feathering switch device. The above differences will affect the flight training effect of pilots. Summary of the invention
[0003] The utility model aims to solve the problem that the prior art flight simulator engine emergency feathering switch device uses a potentiometer for control and has a different sense of control force from the real aircraft engine emergency feathering switch device, and to provide a novel flight simulator engine emergency feathering switch device.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a technical solution: an emergency propeller switch device for a flight simulator engine, comprising: a switch body. The switch body has a switch housing, a switch shaft, a guide connecting shaft, a potentiometer and a damping component. The switch shaft, the guide connecting shaft and the input shaft of the potentiometer have a common vertical axis. The switch shaft drives the input shaft of the potentiometer to rotate synchronously through the guide connecting shaft. The damping component has a transverse rocker arm, a steel ball and a spring. The switch shaft is fixedly connected to the transverse rocker arm and the two act synchronously. One end face of the transverse rocker arm has a rocker arm blind hole. The steel ball and the spring are inside the rocker arm blind hole. The steel ball abuts against the inner surface of the switch housing. The elastic force of the spring acts on the steel ball so that the steel ball always maintains a state of abutting against the inner surface of the switch housing.
[0005] As a preferred solution for the emergency propeller switch device of the flight simulator engine, the lower end of the switch shaft cooperates with the axial hole of the upper end of the guide connecting shaft, and the lower end of the guide connecting shaft is fixedly connected to the input shaft of the potentiometer.
[0006] As a preferred solution of the emergency propeller-feathering switch device for the flight simulator engine, it further includes: a decorative hydraulic pipeline, and the switch body is fixedly connected to the decorative hydraulic pipeline.
[0007] Compared with the prior art, the beneficial effects of the present invention are at least as follows: a damping component is added to simulate the operating feel of an emergency feathering switch device of a real engine, thereby improving the flight training effect of pilots.

[0012] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. It should be noted that the description of these implementations is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0013] See also Figures 1 to 4 , shown in the figure is a flight simulator engine emergency propeller switch device.
[0014] The flight simulator engine emergency feathering switch device comprises: a switch knob 1, an end cover 2, a switch body 3, a decorative hydraulic pipeline, a base 4, a potentiometer 5, etc. The switch body 3 is fixedly connected to the decorative hydraulic pipeline. That is, the flight simulator engine emergency feathering switch device and the real aircraft engine emergency feathering switch device are consistent in appearance, with the purpose of improving the flight training effect of pilots.
[0015] In some embodiments, the decorative hydraulic pipeline has a pipeline connector 6 and a hydraulic pipeline 7. The pipeline connector 6 is formed on the switch body 3. The pipeline connector 6 is connected to the hydraulic pipeline 7.
[0016] The switch body 3 comprises a switch shaft 31, a switch housing 32, a damping component (a lateral rocker arm 33, a spring 34 and a steel ball 35), a guide connecting shaft 36 and a potentiometer mounting plate 37. The switch shaft 31, the guide connecting shaft 36 and the input shaft of the potentiometer 5 have a common vertical axis. The switch knob 1 is fixed to the upper end of the switch shaft 31. The end surface of the lower end of the switch shaft 31 has a shaft hole. The upper end of the guide connecting shaft 36 is inside the shaft hole and the two are matched with each other, so that the switch shaft 31 can be vertically displaced along the guide connecting shaft 36 or drive the guide connecting shaft 36 to rotate synchronously. The lower end of the guide connecting shaft 36 is fixedly connected to the input shaft of the potentiometer 5. That is, the switch shaft 31 can drive the input shaft of the potentiometer 5 to rotate synchronously through the guide connecting shaft 36.
[0017] In some embodiments, the lower end of the guide connecting shaft 36 is fixedly connected to the input shaft of the potentiometer 5 by a set screw.
[0018] The damping component is used to provide the control damping of the emergency feathering switch device of the flight simulator engine, simulating the control force feeling of the emergency feathering switch device of the real aircraft engine. Specifically, the damping component comprises a transverse rocker arm 33, a spring 34 and a steel ball 35. The switch shaft 31 is fixedly connected to the transverse rocker arm 33 and the two move synchronously. One end surface of the transverse rocker arm 33 has a rocker arm blind hole. The steel ball 35 and the spring 34 are arranged inside the rocker arm blind hole. The steel ball 35 abuts against the inner surface of the switch housing 32. The elastic force of the spring 34 acts on the steel ball 35, so that the steel ball 35 always maintains a state of abutting against the inner surface of the switch housing 32. When the switch shaft 31 is rotated, the switch shaft 31 rotates synchronously with the transverse rocker arm 33, and the transverse rocker arm 33 drives the steel ball 35 to move along the inner surface of the switch housing 32. During the displacement process, the friction generated between the steel ball 35 and the inner surface of the switch housing 32 is the control damping.
[0019] In some embodiments, the shape of the switch knob 1 is designed according to ergonomics to increase the comfort of holding and operating.
[0020] In some embodiments, the potentiometer 5 may be a high-precision potentiometer to improve sampling accuracy.
[0021] In some embodiments, the inner surface of the switch housing 32 includes a lower limit groove, an upper limit groove, and a transition groove between the lower limit groove and the upper limit groove. The steel ball 35 is initially inside the lower limit groove. The switch shaft 31 is rotated and lifted, and the switch shaft 31 synchronously drives the lateral rocker arm 33. At this time, the steel ball 35 leaves the lower limit groove and reaches the upper limit groove through the transition groove. The switch shaft 31 is rotated in the opposite direction and pressed down, and the steel ball 35 is reset.
[0022] The above only expresses the implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
