[0006] The motor assembly is driven by the control signals of the ARM processor and includes a left servo motor, a right servo motor, and a rear dual-redundant servo motor. The left servo motor, the right servo motor, and the rear dual-redundant servo motor are connected to the four-quadrant inclined pulley assembly via cable drive and then connected to the seat.
[0007] The present invention is further defined in that the ARM processor is connected to the left servo motor, the right servo motor and the rear dual-redundant servo motor through a three-channel FOC motor drive circuit.
[0008] Furthermore, the seat is equipped with a limiter for left and right tilt, with a maximum tilt angle of 30°.
[0009] Furthermore, it also includes a scene display installed at the front end of the suspended platform.

[0018] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings, but the protection scope of this utility model is not limited to the described embodiments.
[0019] Example 1:
[0020] A VR paragliding simulator for cultural tourism, its structural diagram is shown below. Figure 1 and Figure 2 As shown, it includes a base 1, a column 2, a suspension platform 3, a seat 5, and an ARM processor.
[0021] The base 1 is a rectangular platform, serving as the foundation support for the entire simulator. A column 2 is mounted on each side of the upper surface of the base 1 to support the suspension platform. The suspension platform 3, a rectangular platform, is fixedly mounted above the two columns 2 and is used to mount the seat and other components. A skin 4 covers the top of the suspension platform 3, simulating the appearance of a paraglider. The seat 5, mounted at the lower end of the suspension platform, is fixed to the lower end of the suspension platform 3, allowing the user to sit and experience the ride. The seat 5 has left and right tilt limiters, with a maximum tilt angle of 30°. A scene display 12 is located at the front of the suspension platform 3 to display the virtual scene. A touch screen 13 is mounted on the columns 2 for user operation and control.
[0022] In addition, left pull rods 6 and right pull rods 7 are provided on both sides of the seat 5. A motor assembly is installed on the suspension platform 3. Force sensors 11 are respectively installed on the left pull rods 6 and right pull rods 7. The force sensors transmit quantized signals to the ARM processor through Hall encoders. The motor assembly is driven by the control signals of the ARM processor and includes a left servo motor 8, a right servo motor 9, and a rear dual-redundant servo motor 10. The left servo motor 8, right servo motor 9, and rear dual-redundant servo motor 10 are connected to the four-quadrant inclined pulley assembly and then to the seat 5 via cable drive. At the same time, the ARM processor is connected to the left servo motor 8, right servo motor 9, and rear dual-redundant servo motor 10 through a three-channel FOC motor drive circuit. The main control circuit diagram of the ARM processor is shown below. Figure 4 As shown, the ARM processor is the core processing unit, responsible for receiving user input signals, processing logic control, and outputting control signals to the actuator. The ARM processor outputs control signals through ports PB3, PB7, and PB8, which are respectively connected to the three-channel FOC motor drive circuit. A circuit diagram of a three-channel FOC motor drive circuit is provided in this embodiment as follows: Figure 5 As shown, the other two drive circuits are the same as this circuit, and will not be described in detail.
[0023] This embodiment provides a VR paragliding simulator for cultural tourism, the working principle of which is illustrated in the following diagram. Figure 3 As shown, the specific working principle is as follows:
[0024] The left pull rod 6 detects the user's operation on it via a force sensor 11 and a Hall encoder, transmitting the signal to the ARM processor. The ARM processor controls the left servo motor 8 and the rear dual-redundant servo motor 10 based on the input signal from the left pull rod 6. Similarly, the right pull rod 7 detects the user's operation on it via a force sensor 11 and a Hall encoder, transmitting the signal to the ARM processor. The ARM processor controls the movement of the right servo motor 9 and the rear dual-redundant servo motor 10 based on the input signal from the right pull rod 7.
[0025] Specifically: When the user pulls the left lever 6, the right servo motor 9 winds up the rope, and the left servo motor 8 releases the rope simultaneously. The seat 5 tilts to the left, with the tilt angle proportional to the pressure value, a maximum tilt angle of 30°, and a mechanical limit. When the user pulls the right lever 7, the left servo motor 8 winds up the rope, and the right servo motor 9 releases the rope simultaneously. The seat 5 tilts to the right, with the tilt angle proportional to the pressure value, a maximum tilt angle of 30°, and a mechanical limit. When the user pulls both the left lever 6 and the right lever 7 simultaneously, the rear dual redundant servo motor 10 controls the lifting and lowering movement of the seat 5, and the left servo motor 8 and the right servo motor 9 release the rope proportionally, achieving the tilt angle adjustment of the seat 5.
[0026] This invention allows users to control the seat's height, tilt, and pitch by pulling a lever, similar to real paragliding. Users can interact very naturally without complex training. This intuitive operation not only lowers the barrier to entry but also enhances the user's sense of control and participation in the virtual environment, allowing them to focus more on the experience itself. Compared to traditional VR systems with single-controller interaction or limited gesture recognition, this simulator uses multi-node motors to simulate pitch / roll, increasing the dimensions and richness of interaction. Users can more realistically feel the dynamic changes in the virtual environment through body tilting and lever manipulation, achieving a more natural and fluid interactive experience.
[0027] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
