Description

Technical Field

[0001] This invention relates to the field of human-computer interaction and motion control technology, and in particular to an adjustable throttle mechanism. Specifically, it relates to a throttle mechanism applicable to flight simulators, racing simulators, engineering machinery simulators, and other fields, which has the functions of manual operation, electric follow-up, adjustable damping, and switchable angle limit. Background Technology

[0002] In high-end training and entertainment equipment such as flight simulators and racing simulators, the throttle is one of the core control input devices. Its realistic feel and diverse functions directly affect the user's immersion and training effectiveness. However, traditional throttle devices are typically single-function and have the following shortcomings: 1. Limited drive system: Most are purely manual operation, lacking the automatic follow-up function of motor drive, and cannot simulate advanced scenarios such as autopilot, autothrottle or force feedback of aircraft. 2. Fixed operating feel: The rotation damping is not adjustable or has a limited adjustment range, which cannot meet the different needs of different users for control force in different flight stages (such as cruise and takeoff); 3. Fixed travel range: The range of rotation angles is fixed, making it impossible to quickly switch the effective travel range according to different aircraft models or operating modes (such as idle-takeoff and reverse thrust), resulting in poor flexibility; 4. Lack of accurate feedback: Low angle detection accuracy or complex structure makes it difficult to achieve high-precision closed-loop position control.

[0003] Therefore, there is an urgent need for a throttle movement mechanism that is highly integrated, fully functional, easy to adjust, and highly reliable. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing an adjustable throttle movement mechanism that is convenient to adjust, highly reliable, and integrates multiple functions such as manual operation, follow-up control, stepless damping adjustment, multi-level angle limit switching, and high-precision angle detection.

[0005] The technical problem to be solved by the present invention is achieved through the following technical solution. The present invention is an adjustable throttle movement mechanism, including a mounting base, a rocker arm assembly, a follower assembly, a damping assembly, and an angle detection assembly, wherein a rotation axis is rotatably mounted on the mounting base; The joystick assembly is used as a manual operation input end. The joystick assembly is operably connected to the rotation axis through a linkage mechanism, which is used to convert the operation input into rotation output. The follower component is mounted on the mounting base and is used to provide power drive for the rotation axis to achieve automatic follow-up; The damping assembly is mounted on the mounting base and connected to the rotation axis to provide continuously adjustable rotational damping for the rotation axis. The angle detection component is used to detect the rotation angle of the rotating axis in real time. The angle detection component includes a magnet fixedly installed on the rotating axis to rotate synchronously with it and a Hall sensor installed on the mounting base and arranged corresponding to the magnet.

[0006] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the adjustable throttle movement mechanism described above, the mounting base is a base plate, the rotation axis is a third rotating shaft, a third bracket and a first bracket are fixedly installed on the base plate, and the third rotating shaft is supported on the third bracket and the first bracket by a fifth bearing and a sixth bearing, respectively.

[0007] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: For the adjustable throttle mechanism described above, the damping component includes a bushing, an elastic pressure rod, an adjusting knob, and a limiting member. The bushing is fitted onto the axis of rotation; The elastic pressure bar is mounted on the mounting base, and a mounting hole that mates with the outer wall of the bushing is provided on the elastic pressure bar. The adjustment knob is threadedly connected to the elastic pressure rod and is used to deform the elastic pressure rod when rotated, thereby applying a radial clamping force to the rotation axis through the bushing to generate damping. The limiting element, mounted on the elastic pressure rod, is used to limit the maximum screw-in stroke of the adjusting knob, thereby limiting the maximum value of the damping.

[0008] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: for the adjustable throttle movement mechanism described above, the contact surface between the adjustment knob of the damping component and the elastic pressure rod is provided with a rounded corner.

[0009] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the adjustable throttle movement mechanism described above, the follow-up component includes a motor, a gear reduction system driven by the motor, and a second bracket for supporting the gear reduction system, the second bracket being mounted on the first bracket; The gear reduction system includes a first gear, a second gear, a third gear, a fourth gear, and a fifth gear that mesh with each other, with the fifth gear fixedly mounted on the rotation axis; The motor drives the first gear, which then transmits power through the second, third, and fourth gears to the fifth gear, thereby driving the rotation axis to rotate.

[0010] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: For the adjustable throttle mechanism described above, the mechanism further includes an angle limiting mechanism, which includes multiple steps and a stop lever. The multi-level steps are set on the third bracket of the mounting base; The stop lever is vertically mounted on the rocker assembly, and a bearing is provided at the end of the stop lever. The stop lever has a low position and a high position. In the low position, the bearing at the end of the stop bar abuts against the lowest step in the multi-stage steps to limit the first rotation angle range; In the high position, the bearing at the end of the stop bar abuts against the highest step in the multi-stage steps to limit a second rotation angle range greater than the first rotation angle range.

[0011] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: For the adjustable throttle mechanism described above, the rocker assembly includes a rocker arm, a handle, a first slide rod, a second slide rod, and a swing arm. The rocker arm is operably connected to the rotation axis via a linkage mechanism; The handle is hinged to the rocker arm; The first slider is slidably set along the horizontal direction of the rocker arm; The second slide bar is slidably disposed along the axial direction of the rocker arm and is connected to the stop bar; The swing arm is rotatably mounted inside the rocker arm, and two strip-shaped grooves are also provided on the swing arm; The handle is also provided with a strip groove. The handle is hinged to the rocker arm by the first pin and connected to the first slide rod by the second pin. The second pin slides in cooperation with the strip groove. A third pin is fixedly installed on the first slide rod and a fourth pin is fixedly installed on the second slide rod. The third pin and the fourth pin extend into the two strip grooves on the rocker arm respectively. Pressing the handle drives the first slide rod to slide via the second pin, which in turn drives the rocker arm to rotate via the third pin. The rotation of the rocker arm drives the second slide rod and the stop lever to rise and fall via the fourth pin, thereby switching the stop lever between the low and high positions.

[0012] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the adjustable throttle movement mechanism described above, the linkage mechanism is a five-bar linkage inside the rocker arm: pressing the handle is hinged by the first pin, and the second pin slides in the slotted groove to drive the first slide rod to move horizontally. The first slide rod slides in the slotted groove of the rocker arm through the third pin to drive the rocker arm to rotate around the fifth pin. The rocker arm then slides in another slotted groove through the fourth pin to drive the second slide rod and the stop lever to move axially up and down, thereby converting the pressing action of the handle into the raising and lowering of the stop lever, realizing the two-stage switching of the angle limit.

[0013] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: In the adjustable throttle movement mechanism described above, the stop lever is biased to a low position by a spring in the angle limiting mechanism.

[0014] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: For the adjustable throttle mechanism described above, a method of using the adjustable throttle mechanism includes the following steps: (1) Initial settings According to the needs of the simulation scenario or personal operating preferences, rotate the adjustment knob of the damping component to make the elastic pressure rod deform accordingly, and apply radial clamping force to the rotation axis through the bushing to set the required rotation damping magnitude; (2) Angle limit mode selection Select the joystick rotation angle range based on the current simulator model or operating stage: Small angle mode: The stop lever is in a low position under the bias of the spring, and its end bearing abuts against the low step on the third bracket. The rotation of the rocker arm is limited to the first rotation angle range. Large Angle Mode: When the operator presses the handle on the rocker assembly, the second pin driven by the groove on the handle drives the first slide rod to slide. The first slide rod drives the rocker arm to rotate around the fifth pin through the third pin. The rocker arm then drives the second slide rod and the stop rod to slide upward against the force of the spring to the high position through the fourth pin. At this time, the bearing at the end of the stop rod abuts against the high step on the third bracket, and the rotation angle range of the rocker arm switches to a larger second rotation angle range. Reset operation: Release the handle, and the spring will automatically push the lever back to the low position, restoring the small angle mode; (3) Manual control mode In pure manual mode, the operator directly holds and turns the joystick. The joystick drives the rotation axis to rotate through the internal linkage mechanism. The damping component provides the set rotation resistance. The angle detection component detects the rotation angle of the rotation axis in real time and outputs a feedback signal. The operator can obtain the same force feedback feel as the real throttle. (4) Automatic follow-up mode In scenarios requiring automatic follow-up, the motor of the follow-up component is powered on and started. After being decelerated and increased in torque through the first gear, second gear, third gear and fourth gear, it drives the rotating shaft to rotate through the fifth gear, which in turn drives the rocker arm to move in the minimum angle mode, thereby realizing automatic follow-up control of the throttle. At this time, the operator can still manually control the motor using the joystick. Once the operator intervenes, the motor enable can be quickly cut off, and the system can enter manual mode. (5) Angle real-time feedback and closed-loop control Throughout the operation, the magnet rotates synchronously with the rotation axis. The Hall sensor mounted on the third bracket detects the angular position of the magnet in real time and outputs a high-precision angle signal for the position closed-loop control of the host computer, thereby achieving precise throttle position management.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Highly integrated functions: A single mechanism simultaneously realizes manual operation, motor follow-up drive, stepless damping adjustment, angle limit switching and high-precision angle detection, which greatly enriches the throttle control interaction capabilities and simulation dimensions of flight simulation scenarios; 2. Realistic and Adjustable Hand Feel: Through the innovative elastic pressure bar and bushing structure, continuous, smooth and stepless adjustment of rotational damping is achieved. Users can customize the operating force according to their personal habits or simulated scenario needs. The overload protection mechanism also improves reliability. 3. Flexible switching of angle limit: Through the ingenious internal linkage mechanism of the rocker, the pressing action of the handle is converted into the raising and lowering of the stop bar, realizing the rapid switching of mechanical angle limit in cooperation with external steps. The structure is reliable and the feedback is clear. 4. Smooth and precise transmission: The servo system with multi-stage gear reduction has high output torque, smooth operation and low noise; the non-contact magnetic encoding angle detection scheme has a long life, high accuracy and no wear, providing reliable feedback for closed-loop control. 5. Compact and reliable structure: All functional modules are integrated into one unit with the base plate as the base, resulting in a compact structure and good rigidity; key moving pairs are supported and limited by bearings, resulting in low friction, long service life, and smooth operation.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1-7 An adjustable throttle mechanism is described, the core function of which is to achieve dual drive of manual operation and automatic follow-up. It integrates continuously adjustable rotational damping and multi-level switchable rotational angle limit. The mechanism uses a rocker arm assembly 600 as the manual operation input end, provides adjustable rotational resistance through a damping assembly 400, achieves automatic drive through a follow-up assembly 500, and converts the pressing action of the handle 601 into the raising and lowering of the lever 606 through a linkage mechanism in the rocker arm assembly 600, thereby switching the cooperation with different steps on the third bracket 203 to achieve stepless adjustment of the rotation angle range of the rocker arm 602. The rotation angle of the third rotating shaft 301 is detected in real time by a magnet 305 fixed at the end in conjunction with a Hall sensor 306, providing feedback for precise control.

[0019] Overall structure and transmission layout: The adjustable throttle mechanism uses the base plate 100 as an integrated mounting base. The first bracket 201 and the third bracket 203 are fixedly mounted on the base plate 100. Both are provided with high-precision bearing mounting holes. The third rotating shaft 301 has a stepped shaft structure. Its two ends are supported by the fifth bearing 303 (mounted on the third bracket 203) and the sixth bearing 304 (mounted on the first bracket 201) to achieve stable rotation with low friction. A cylindrical countersunk hole is opened on the end face of the third rotating shaft 301 near the third bracket 203. A magnet 305 is fixed in the hole so that it rotates coaxially and synchronously with the third rotating shaft 301. A sensor mounting position is provided at the corresponding position of the third bracket 203 for mounting a Hall sensor 306 to detect the rotational attitude of the magnet 305, thereby outputting the real-time angle and position signal of the third rotating shaft 301.

[0020] Damping component 400: The damping assembly 400 is mounted on the first bracket 201 to provide continuously adjustable frictional resistance for the rotation of the third rotating shaft 301. Its core components include an elastic pressure rod 401 made of elastic metal, a bushing 402 made of wear-resistant non-metallic material, an adjusting knob 403, and a limiting screw 404. The elastic pressure rod 401 has a through-slot in the middle, forming a pair of elastic cantilever arms, namely an upper cantilever 4011 and a lower cantilever 4012. The bushing 402 is fitted onto the... The outer wall of the third rotating shaft 301 is embedded in the circular mounting hole of the elastic pressure rod 401. The adjusting knob 403 has a stepped structure, and its threaded section passes through the through hole of the upper cantilever 4011 of the elastic pressure rod 401 and engages with the threaded hole of the lower cantilever 4012. When the adjusting knob 403 is turned, its coarse cylindrical section presses the upper cantilever 4011 downward, causing the elastic pressure rod 401 to contract. This applies a radial clamping force to the third rotating shaft 301 through the bushing 402, generating damping. The degree of tightening is proportional to the magnitude of the damping force, achieving stepless adjustment. The lower cantilever 4012 is provided with a limit screw 404 to limit the maximum downward stroke of the upper cantilever 4011, thereby limiting the maximum value of the damping force and providing overload protection. The contact surface between the adjusting knob 403 and the elastic pressure rod 401 has rounded corners to ensure smooth contact when the elastic pressure rod 401 deforms, avoiding hard damage.

[0021] Follow-up component 500: The follower assembly 500 is used to automatically drive the adjustable throttle mechanism, including a motor 501, first gears 502 to fifth gears 302, a first rotating shaft 504, a second rotating shaft 507, first bearings 508 to fourth bearings 511, and a second bracket 202. The motor 501 is fixed to the first bracket 201, and the second bracket 202 is fixed to the outside of the first bracket 201 to enhance the rigidity of the transmission system. The first rotating shaft 504 is supported by the first bearing 508 (mounted in the first bracket 201) and the second bearing 509 (mounted in the second bracket 202). The second rotating shaft 507 is supported by the third bearing 510 (mounted in the first bracket 201) and... The fourth bearing 511 (mounted on the second bracket 202) provides support; the first gear 502 is fixed to the output shaft of the motor 501 and meshes with the second gear 503 fixed to the first rotating shaft 504, and the two are of the same size; the second gear 503 meshes with the third gear 505 with a larger diameter to achieve the first stage of reduction; the third gear 505 and the fourth gear 506 are coaxially fixed on the second rotating shaft 507; the fourth gear 506 meshes with the fifth gear 302 fixed on the third rotating shaft 301 to achieve the second stage of reduction. Through this multi-stage gear reduction system, the high-speed rotation of the motor 501 is converted into the low-speed, high-torque output of the third rotating shaft 301, achieving smooth follow-up.

[0022] Joystick assembly 600 and its linkage mechanism: The rocker arm assembly 600 is the core component for enabling manual operation and angle limit switching. It includes a handle 601, a first slide bar 603, a second slide bar 604, a rocker arm 605, a stop bar 606, a spring 607, first pins 608 to fifth pins 612, a fixing block 613, and a decorative cover 614. The rocker arm 602 integrates a double-slider rocker arm mechanism: the second slide bar 604 can slide up and down along the axial direction of the rocker arm 602, and its end is connected to the stop bar 606 via the fixing block 613. A downward restoring force is provided by the spring 607, keeping the stop bar 606 in a low position. The first slide bar 603 can... The rocker arm 602 slides back and forth horizontally. The swing arm 605 is rotatably mounted inside the rocker arm 602 via the fifth pin 612. The swing arm 605 has two strip-shaped grooves. The third pin 610, which is fixed to the first slide arm 603, and the fourth pin 611, which is fixed to the second slide arm 604, extend into these two grooves respectively. The handle 601 is hinged to the rocker arm 602 via the first pin 608. The strip-shaped groove on it cooperates with the second pin 609, which is fixed to the end of the first slide arm 603. The decorative cover 614 is assembled on the outside of the rocker arm assembly 600, serving as decoration, dustproofing, and safety protection.

[0023] During operation, pressing the handle 601 drives the second pin 609 to slide in its slot, causing the first slide rod 603 to move back and forth. The movement of the first slide rod 603 drives the rocker arm 605 to rotate around the fifth pin 612 via the third pin 610. The rotation of the rocker arm 605 then drives the second slide rod 604 to slide up and down via the fourth pin 611, thereby converting the operation of the handle 601 into the lifting and lowering movement of the stop lever 606.

[0024] Angle limit and adjustment mechanism: The rotation angle of the rocker arm 602 is mechanically limited by the engagement of the stop rod 606 with the multi-step mechanism on the third bracket 203. A bearing 6061 is installed at the end of the stop rod 606. Under the action of the spring 607, the stop rod 606 is in the low position, and its end bearing 6061 abuts against the low step 2031 of the third bracket 203. At this time, the rotation angle range of the rocker arm 602 is relatively small. When the stop rod 606 is driven to the high position by the operation of the handle 601, the bearing 6061 of the stop rod 606 abuts against the high step 2032 of the third bracket 203, thereby obtaining a larger rotation angle range. The contact between the bearing 6061 and the step converts sliding friction into rolling friction, effectively reducing wear and allowing the rotation angle range of the rocker arm 602 to be smoothly adjusted under the action of the rotation of the bearing 6061 after the contact limit is reached.

[0025] The method of using the adjustable throttle mechanism provided by the present invention includes the following steps: (1) Initial settings - damping adjustment According to the needs of the simulation scenario or personal operating preferences, rotate the adjustment knob 403 of the damping component 400 to cause the elastic pressure rod 401 to deform accordingly, and apply radial clamping force to the third rotating shaft 301 through the bushing 402, thereby setting the required rotational damping magnitude; The deeper the adjusting knob 403 is screwed in, the greater the damping; when the maximum stroke limited by the limit screw 404 is reached, the damping reaches its maximum value, thus preventing overload damage. (2) Angle limit mode selection Select the rotation angle range of joystick 602 based on the current simulator model or operating stage: Small angle mode (default state): The lever 606 is in a low position under the bias of the spring 607, and its end bearing 6061 abuts against the low step 2031 on the third bracket 203. The rotation of the rocker arm 602 is limited to the first rotation angle range, which is suitable for small stroke scenarios such as cruise phase or reverse thrust operation. Large Angle Mode (Switch State): When the operator presses the handle 601 on the joystick assembly 600, the second pin 609 driven by the groove on the handle 601 drives the first slide bar 603 to slide. The first slide bar 603 drives the swing arm 605 to rotate around the fifth pin 612 through the third pin 610. The swing arm 605 then drives the second slide bar 604 and the stop bar 606 to slide upward to the high position against the force of the spring 607 through the fourth pin 611. At this time, the bearing 6061 at the end of the stop bar 606 abuts against the high step 2032 on the third bracket 203. The rotation angle range of the joystick 602 is switched to a larger second rotation angle range, which is suitable for large stroke scenarios such as takeoff and acceleration. Reset operation: Release handle 601, spring 607 will automatically push lever 606 back to the low position, restoring the small angle mode; (3) Manual control mode In pure manual mode, the operator directly holds and rotates the joystick 602. The joystick 602 drives the third rotating shaft 301 to rotate through the internal linkage mechanism. The damping component 400 provides the set rotation resistance. The angle detection component detects the rotation angle of the third rotating shaft 301 in real time and outputs a feedback signal. The operator can obtain the same force feedback feel as the real throttle. (4) Automatic follow-up mode In scenarios requiring automatic follow-up (such as autonomous driving, automatic throttle, force feedback training, etc.), the motor 501 of the follow-up component 500 is powered on and started. After being decelerated and increased in torque through the first gear 502, the second gear 503, the third gear 505, and the fourth gear 506, it drives the third rotating shaft 301 to rotate through the fifth gear 302, which in turn drives the rocker arm 602 to move in the minimum angle mode, thereby realizing automatic follow-up control of the throttle. At this time, the operator can still manually control the throttle through the rocker arm 602. After manual intervention, the motor enable can be quickly cut off and the manual mode can be entered. (5) Angle real-time feedback and closed-loop control Throughout the operation, the magnet 305 fixed at the end of the third rotating shaft 301 rotates synchronously with the third rotating shaft 301. The Hall sensor 306 installed on the third bracket 203 detects the angular position of the magnet 305 in real time and outputs a high-precision angle signal. This signal can be used for the position closed-loop control of the host computer to achieve precise throttle position management.

[0026] In summary, this invention discloses an adjustable throttle mechanism. The rocker arm assembly serves as a manual operation input and can switch angle limits. It contains an internal linkage mechanism that converts the pressing action of the handle into the raising and lowering of the lever, allowing the lever to engage with different steps on a third bracket fixed to the base, thereby achieving two or more rapid switching of the rocker arm's rotation angle range. The damping assembly adjusts the deformation of the elastic pressure rod via a knob, applying a continuously adjustable radial damping force to the rotation axis, and includes a limiter to prevent overload. The follow-up assembly provides smooth automatic follow-up drive to the rotation axis through a multi-stage gear reduction system driven by a motor. The angle detection assembly uses a non-contact solution with a magnet and a Hall sensor to detect the rotation angle in real time with high precision.

[0027] This invention features high integration, combining manual / follow-up motor drive, stepless damping adjustment, rapid stroke switching, and precise feedback, making it particularly suitable for high-end simulator equipment.

The handle is hinged to the rocker arm by the first pin and connected to the first slide rod by the second pin. The second pin slides in cooperation with the strip groove. A third pin is fixedly installed on the first slide rod and a fourth pin is fixedly installed on the second slide rod. The third pin and the fourth pin extend into the two strip grooves on the rocker arm respectively. Pressing the handle drives the first slide rod to slide via the second pin, which in turn drives the rocker arm to rotate via the third pin. The rotation of the rocker arm drives the second slide rod and the stop lever to rise and fall via the fourth pin, thereby switching the stop lever between the low and high positions.

8. The adjustable throttle mechanism according to claim 7, characterized in that: The linkage mechanism is a five-bar linkage inside the rocker arm: pressing the handle is hinged by the first pin, and the second pin slides in the slotted groove to drive the first slide rod to move horizontally. The first slide rod slides in the slotted groove of the rocker arm via the third pin to drive the rocker arm to rotate around the fifth pin. The rocker arm then slides in another slotted groove via the fourth pin to drive the second slide rod and the stop rod to move axially up and down, thereby converting the pressing action of the handle into the raising and lowering of the stop rod, realizing two-stage switching of the angle limit.

9. The adjustable throttle mechanism according to claim 6, characterized in that: In the angle limiting mechanism, the stop lever is biased to a low position by a spring.

10. A method of using an adjustable throttle mechanism, characterized in that: This method is a method of using the adjustable throttle mechanism as described in any one of claims 1-9, comprising the following steps: (1) Initial settings According to the needs of the simulation scenario or personal operating preferences, rotate the adjustment knob of the damping component to make the elastic pressure rod deform accordingly, and apply radial clamping force to the rotation axis through the bushing to set the required rotation damping magnitude; (2) Angle limit mode selection Select the joystick rotation angle range based on the current simulator model or operating stage: Small angle mode: The stop lever is in a low position under the bias of the spring, and its end bearing abuts against the low step on the third bracket. The rotation of the rocker arm is limited to the first rotation angle range. Large Angle Mode: When the operator presses the handle on the rocker assembly, the second pin driven by the groove on the handle drives the first slide rod to slide. The first slide rod drives the rocker arm to rotate around the fifth pin through the third pin. The rocker arm then drives the second slide rod and the stop rod to slide upward against the force of the spring to the high position through the fourth pin. At this time, the bearing at the end of the stop rod abuts against the high step on the third bracket, and the rotation angle range of the rocker arm switches to a larger second rotation angle range. Reset operation: Release the handle, and the spring will automatically push the lever back to the low position, restoring the small angle mode; (3) Manual control mode In pure manual mode, the operator directly holds and turns the joystick. The joystick drives the rotation axis to rotate through the internal linkage mechanism. The damping component provides the set rotation resistance. The angle detection component detects the rotation angle of the rotation axis in real time and outputs a feedback signal. The operator can obtain the same force feedback feel as the real throttle. (4) Automatic follow-up mode In scenarios requiring automatic follow-up, the motor of the follow-up component is powered on and started. After being decelerated and increased in torque through the first gear, second gear, third gear and fourth gear, it drives the rotating shaft to rotate through the fifth gear, which in turn drives the rocker arm to move in the minimum angle mode, thereby realizing automatic follow-up control of the throttle. At this time, the operator can still manually control the motor using the joystick. Once the operator intervenes, the motor enable can be quickly cut off, and the system can enter manual mode. (5) Angle real-time feedback and closed-loop control Throughout the operation, the magnet rotates synchronously with the rotation axis. The Hall sensor mounted on the third bracket detects the angular position of the magnet in real time and outputs a high-precision angle signal for the position closed-loop control of the host computer, thereby achieving precise throttle position management.
