Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of simulator control load test frame, specifically a flight simulator control load test frame. Background Technology
[0002] The flight control system is operated by a joystick. The basic principle of the joystick is to convert the movement of a plastic stick into electronic information that a computer can process. However, the joysticks currently used in flight simulation training are unloaded joysticks, which have poor feedback during simulation training and result in unsatisfactory simulation training effects.
[0003] Therefore, a flight simulator control load test frame is proposed to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a flight simulator control load test frame, including a mounting frame. Universal wheels are respectively provided at the four corners of the mounting frame. The mounting frame is connected to a foot pedal via fastening bolts. A control component and a foot emergency stop switch are respectively provided at the front end of the foot pedal. The control component passes through an elliptical hole at the front end of the foot pedal and extends to the bottom of the foot pedal, connecting to one end of a fisheye bearing connecting component inside the mounting frame. The other end of the fisheye bearing connecting component is connected to a drive component. A control component is also provided inside the mounting frame, and the control component is electrically connected to the foot emergency stop switch and the drive component.
[0005] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0006] This invention features casters at the four corners of the mounting frame, which facilitate the movement of the mounting frame and thus the transport of the device.
[0007] This invention incorporates a joystick, a fisheye bearing connecting assembly, a servo motor, and a reducer. When the joystick is gripped and moved forward and backward, the joystick base below it moves the fisheye bearing connecting assembly back and forth. At this time, the servo motor drives the guide rod to generate a corresponding resistance, accurately replicating the force feedback characteristics of the control stick during flight and improving the realism of the simulated control.

The mounting frame 1 is also provided with a control component 6, which is electrically connected to the foot emergency stop switch 5 and the drive component 8 respectively.
[0016] Specifically, casters 2 are provided at the four corners of the mounting frame 1.

The rear end of the first fisheye bearing 701 is connected to a tension / compression sensor 704 via a first fisheye bearing connecting rod 703. The other end of the tension / compression sensor 704 is connected to the second fisheye bearing 707 via a second fisheye bearing connecting rod 705. The second fisheye bearing 707 has a second shoulder bolt 708 at its front end.
[0020] Specifically, hexagonal nuts 706 are respectively provided on the side of the first fisheye bearing 701 near the first fisheye bearing connecting rod 703 and the side of the second fisheye bearing 707 near the second fisheye bearing connecting rod 705.

The control stick base 403 below the control stick 401 drives the fisheye bearing connecting assembly 7 to move back and forth. At this time, the foot pedal emergency stop switch 5 sends a control signal to the control assembly 6, which controls the servo motor 803 to start. After being reduced in speed by the reducer 804, the servo motor 803 drives the guide rod 805 to rotate. The guide rod 805 provides a reverse force to the fisheye bearing connecting assembly 7, that is, a resistance opposite to the forward or backward swing, accurately reproducing the force feedback characteristics of the control stick in flight and improving the realism of simulated operation.
