[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined Figures 1-5 This invention describes a joystick simulation device for a flying car.

[0025] This utility model embodiment provides a joystick simulation device for a flying car, including: a joystick 1 and a roll mechanism 2, the joystick 1 passing through the roll mechanism 2 and being movably connected to the roll mechanism 2; the joystick 1 is configured to be able to rotate independently or in combination around the X-axis and Y-axis directions to achieve roll and pitch movements.

[0026] As can be seen from the above solution, the joystick simulation device provided by this utility model can meet the complex operation requirements of both flight and land modes, and solves the problem of insufficient motion freedom of the joystick 1 in the existing simulator. By setting the joystick 1, it can realize roll motion around the X-axis and pitch motion around the Y-axis, and the two motions can be performed independently or in combination. For example, in flight mode, independent roll can adjust the left and right tilt angle of the flying car, and independent pitch can adjust the nose height to control the ascent and descent. Combined motion can cope with complex flight attitudes such as tilting and diving. In land driving mode, pitch motion can be associated with throttle / brake, and roll motion can be associated with steering, which greatly improves the maneuverability.

[0027] In this embodiment, the rolling mechanism 2 includes: a base 21, a drive component 22, and a rolling frame 23, as follows: Figures 1-3 As shown, the base 21 has a rectangular cross-section, with the X-axis and Y-axis directions parallel to the lengths of two adjacent sides of the base 21, respectively. The base 21 is provided with a rotating connector 24, such as a spherical bearing. The drive component 22 is fixed to the base 21. One end of the roll frame 23 is rotatably connected to the base 21, and the other end is fixedly connected to the power output end of the drive component 22. The control lever 1 passes through the roll frame 23 along its axial direction and is connected to the rotating connector 24.

[0028] With this configuration, the base 21 has a rectangular cross-section, and the X-axis (roll axis) and Y-axis (pitch axis) are parallel to the adjacent side lengths of the base 21, respectively. This provides a fixed and clear positioning reference for the movement of the joystick 1. That is, the roll motion is performed around the X-axis parallel to one side length of the base 21, and the pitch motion is performed around the Y-axis parallel to the other adjacent side length of the base 21. At the same time, the joystick 1 passes through the roll frame 23 axially, which further constrains the radial sway of the joystick 1, ensuring that the roll and pitch motions are performed accurately along the preset axis, reducing misoperation caused by motion deviation, and solving the defects of ambiguous movement direction and inaccurate attitude control of the joystick 1 in the prior art.

[0029] In some embodiments, the rotating connector 24 is a spherical bearing, with the inner ring of the spherical bearing tightly fitted to the control lever 1, and the outer ring of the spherical bearing connected to the base 21 by bolts. The rotating connector 24 can serve as a fixed fulcrum for the rotation of the control lever 1. When the driver moves the control lever 1 forward, backward, left, or right, the lever body can rotate flexibly around the inner ring of the rotating connector 24, thereby realizing the pitch and roll movements of the control lever 1 and ensuring smooth and seamless pitch movements.

[0030] In some embodiments, the drive element 22 is a motor, which is fixedly mounted on the base 21 via the motor base 3. The rotation shaft of the motor is connected to the end of the roll frame 23. The motor is a drive motor that can output damping force and has an automatic centering function for the drive joystick 1 structure, such as a servo motor.

[0031] Specifically, the servo motor used, when powered on but not receiving a rotation drive signal (i.e., the motor does not rotate actively), generates a stable electromagnetic field inside. When an external force is applied, such as manually rotating the motor shaft to try to change the stationary state of the motor shaft, this electromagnetic field will generate an electromagnetic damping force on the motor rotor. The specific principle is as follows: Utilizing the electromagnetic induction effect and Lenz's law, after the motor is powered on, the stator windings generate a fixed magnetic field. When the rotor is not actively rotating, it is in this magnetic field. When the motor shaft is manually rotated to drive the rotor to rotate, the rotor conductors cut the magnetic field lines of the stator magnetic field, which will induce a current in the rotor windings. The induced current experiences an Ampere force in the stator magnetic field. This Ampere force is in the opposite direction to the rotor's rotation, thus hindering the rotor's movement and ultimately forming a perceptible damping force. The magnitude of this damping force can be precisely controlled by adjusting the current parameters through the motor controller. It also exists continuously without the motor actively rotating, fully meeting the requirements of manual flight mode for force sensing simulation of joystick 1.

[0032] Automatic centering refers to the motor's ability to automatically return the joystick 1 to its initial center position after it deviates from the neutral position in the roll direction. The current rotation angle of the roll frame 23 is detected in real-time by the motor's built-in encoder or an external sensor, and this signal is fed back to the controller. The system presets a neutral position, which is a reference point with a roll angle of 0°. When the joystick 1 is moved, the controller calculates the deviation between the current angle and the neutral position and outputs a corresponding control signal based on the direction of the deviation, driving the motor to rotate. The motor outputs a reverse torque according to the control signal. For example, if the joystick 1 deviates to the left, the motor drives the roll frame 23 to rotate to the right; if it deviates to the right, it drives it to rotate to the left, until the encoder detects that the angle has returned to the neutral position, at which point the motor stops working, achieving automatic centering.

[0033] By setting up a drive component 22, one end of the roll frame 23 is fixedly connected to the power output end of the drive component 22, and the other end is rotatably connected to the base 21, so that the drive component 22 can directly apply torque to the roll frame 23. On the one hand, the drive component 22 can output a damping force opposite to the roll movement direction of the control stick 1, simulating the air resistance on the flying car in real flight, and the magnitude of the damping force can be adjusted by the parameters of the drive component 22 to adapt to the feel requirements of different flight scenarios. On the other hand, when the driver releases the control stick 1, the drive component 22 can drive the roll frame 23 to move the control stick 1 back to the neutral position in the roll direction, realizing automatic centering, reducing the driver's manual reset operation steps, reducing operator fatigue, and making the simulated operation closer to the operating experience of a real flying car.

[0034] Reference Figure 3 , Figure 4 In this embodiment, a base 3 is also included. The base 3 is connected to the base 21 by a connecting rod 4, such as by bolts for detachable connection or by welding connection. The connecting rod 4 can be set vertically to the base 3 to provide support and connection. A limiting groove 5 is provided on the base 3 to limit the movement trajectory of the control lever 1. The bottom end of the control lever 1 moves within the limiting groove 5. A position detection element 6 for collecting position signals is provided at the end of the limiting groove 5. The position detection element 6 can be triggered when the control lever 1 assembly moves to the end of the limiting groove 5.

[0035] This configuration provides reliable and stable support for the entire device via the base 3, and the limiting groove 5 on the base 3 provides a fixed movement path for the bottom end of the joystick 1. Combined with the cooperation of the joystick 1, the roll mechanism 2, and the rotating connector 24, the movement of the joystick 1 can be limited within a preset trajectory, avoiding problems such as left and right deviation or overtravel due to lack of guidance. This ensures that the movement direction of the joystick 1 is precisely matched with the attitude control requirements of the flying car. The position detection element 6 at the end of the limiting groove 5, such as a limit switch, collects the position signal of the joystick 1. When the bottom end of the joystick 1 moves to the end of the limiting groove 5, i.e., the limit position of the pitch movement, such as the foremost or rearmost end, the detection element will be triggered, thereby transmitting the signal that the joystick 1 has reached the endpoint position to the flying car control system, providing reliable data for the automated control of the flying car and improving control accuracy.

[0036] like Figure 1 , Figure 2 , Figure 4 As shown, further, the roll frame 23 is provided with a pitch groove 231 along the X-axis to accommodate the control lever 1, which is used to limit the range of rotation of the control lever 1 around the Y-axis. Preferably, the pitch groove 231 is an arc-shaped groove that is adapted to the movement trajectory of the control lever 1.

[0037] With this configuration, the pitch groove 231 opened along the X-axis of the roll frame 23 provides structural guidance and boundary constraints for the control stick 1. When the control stick 1 passes through the pitch groove 231 and moves back and forth along the groove, the front and rear end walls of the groove directly block the excessive rotation of the stick, preventing the pitch angle of the control stick 1 around the Y-axis from exceeding the preset range, ensuring that the pitch motion always matches the actual attitude control requirements of the flying car. In addition, the pitch groove 231 structure can form a lateral limit on the control stick 1, preventing the control stick 1 from deviating left or right along the X-axis when performing pitch motion. At the same time, it ensures that when the control stick 1 performs roll motion with the roll frame 23, the stick is always in the central area of ​​the pitch groove 231, avoiding jamming between the pitch groove 231 and the stick due to stick deviation. Ultimately, it ensures that the pitch and roll motions are performed independently and smoothly without mutual interference, improving the simulation control accuracy and safety reliability.

[0038] Reference Figure 2 , Figure 5In some embodiments, a positioning structure is provided between the pitch slot 231 and the control stick 1. The positioning structure includes: a plurality of elastic locking members 25 and a locking groove 13. The plurality of elastic locking members 25 are spaced apart in the pitch slot 231 along the motion trajectory of the control stick 1 rotating around the Y-axis. The elastic locking member 25 includes: a receiving housing 251, an elastic member 252, and a locking member 253. The elastic member 252 is disposed in the receiving housing 251. The locking member 253 can be a spherical structure and is at least partially located in the receiving housing 251. For example, the opening of the housing 251 is designed as a constricted structure, that is, the snap-fit ​​253 can partially protrude from the opening of the housing 251 to cooperate with the slot 13. The snap-fit ​​253 abuts against the elastic member 252 and can move along the axial direction of the housing 251. The slot 13 is provided on the control lever 1 and is adapted to the snap-fit ​​253. When the control lever 1 is rotated to a preset position around the Y-axis by the rotating connector 24, the corresponding snap-fit ​​253 can be embedded in the slot 13.

[0039] With this configuration, the elastic locking component 25 is positioned within the pitch groove 231 along the rotational trajectory of the control stick 1 around the Y-axis, i.e., the pitch movement path. Combined with the matching locking slot 13 on the control stick 1, it can achieve physical positioning at multiple pitch positions, such as the neutral position, forward pitch 1, forward pitch 2, backward pitch 1, and backward pitch 2. When the driver rotates the control stick 1 around the Y-axis to the desired position, the locking component 253, under the elastic force of the elastic component 252, engages with the locking slot 13, providing a clear position locking point for the control stick 1, achieving multi-position pitch movement and precise positioning. The locking component 253 produces a noticeable locking sensation when engaged with the locking slot 13. This physical feedback is directly transmitted to the driver's hand, allowing the driver to determine whether the control stick 1 has reached the preset pitch position without relying on visual observation, thus achieving precise positioning. This simulates the operating experience of a real flying car control stick 1, making simulation training closer to actual driving scenarios.

[0040] In addition to its positioning function, when the latch 253 is inserted into the slot 13, it can also provide lateral auxiliary constraint on the pitch movement of the joystick 1, preventing the joystick 1 from shifting left or right during the pitch process and ensuring that the joystick 1 always moves smoothly along the preset pitch trajectory. This forms a double constraint with the trajectory limiting function of the pitch slot 231, further ensuring the stability of the pitch movement.

[0041] In this embodiment, the joystick 1 includes a hand grip 11 and a stick body 12. The hand grip 11 and the stick body 12 are detachably connected. The stick body 12 passes through the pitch groove 231 along the axial direction and cooperates with the rotating connector 24. For example, the inner ring of the spherical bearing is tightly fitted with the stick body 12. The stick body 12 is provided with a slot 13.

[0042] With this design, the handgrip 11 and the lever 12 can be separated as independent components. When the handgrip 11 wears down or its surface ages due to long-term gripping, or when the lever 12 deforms or wears down due to its interaction with the roll mechanism 2 and the rotating connector 24, it is not necessary to replace the entire lever 1. Only the damaged handgrip 11 or the lever 12 needs to be disassembled and replaced separately, which greatly simplifies the maintenance process.

[0043] Preferably, the outer surface of the handheld part 11 is provided with anti-slip texture, which is strip-shaped or grid-shaped. This can increase the contact friction between the hand and the surface of the handheld part 11. Especially in simulated flight training, the pilot needs to hold the control stick 1 for a long time. The anti-slip texture can enhance the friction constraint through physical structure and prevent the hand from sliding relative to the handheld part 11.

[0044] Furthermore, such as Figure 2 As shown, fasteners 7, such as fastening nuts, are provided on the upper and lower sides of the rotating connector 24 on the rod body 12, and the rod body 12 and the rotating connector 24 are fixed by the fasteners 7.

[0045] Since the rotating connector 24, as the core support component for the rotation of the control lever 1, needs to maintain a stable axial position relationship with the lever 12, the fasteners 7 on the upper and lower sides of the lever 12 fix the rotating connector 24 in the preset axial position of the lever 12 through clamping force. This can directly limit the up and down movement of the lever 12 and the rotating connector 24 along the axis of the lever 12, ensuring that the rotating connector 24 always provides precise rotational support for the lever 12.

[0046] In some embodiments, the bottom of the base 3 is provided with a shock-absorbing pad, which is made of rubber. During the simulation training, when the driver moves the control stick 1 to perform roll and pitch operations, an operating impact force will be generated. This impact force can easily cause vibration between the base plate and the mounting surface. The shock-absorbing pad absorbs this vibration energy through its own elastic deformation. The shock-absorbing pad is set between the bottom of the base 3 and the mounting surface to prevent the base 3 from shifting when affected by operating force or vibration, further fixing the mounting position of the base 3 and providing a stable foundation support for the entire control stick simulation device.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
