Description

Technical Field

[0001] This utility model relates to the field of flight simulator technology, and in particular to a foot pedal simulation device and a transport aircraft simulator. Background Technology

[0002] Because of the complex flight environment and varied flight attitudes of aircraft, the data fed back to the rudder changes rapidly. Pilots need to make corresponding judgments and execute operations quickly based on the force feedback data. This requires pilots to accumulate experience through long-term training on real aircraft. Since direct aircraft training is less safe and less cost-effective, aircraft pilot simulators are currently used to simulate the control force feedback of real aircraft.

[0003] The transport aircraft has a pilot's seat and a co-pilot's seat, both equipped with left and right foot pedals. These foot pedals are linked; the left pedal controls the rudder to turn left, causing the aircraft to nose-to-left, while the right pedal controls the rudder to turn right, causing the aircraft to nose-to-right. Additionally, during taxiing or landing, both foot pedals can be used to control the aircraft's brakes.

[0004] Existing transport aircraft pilot simulators do not consider the linkage between the foot pedals of the driver and co-pilot. The foot pedals of the driver and co-pilot are controlled independently, and force feedback is applied to each foot pedal separately, resulting in poor simulation realism and affecting the simulation training effect. In addition, the overall fore-and-aft travel range of the foot pedals is fixed and cannot be adjusted, making it unsuitable for the operating needs of trainees of different heights. Utility Model Content

[0005] To address the technical problem in the existing transport aircraft driving simulators mentioned above, which do not consider the linkage between the driver and co-pilot's foot pedals, and where the driver and co-pilot's foot pedals are controlled independently with force feedback applied to each pedal separately, resulting in poor simulation realism and affecting the simulation training effect, this utility model provides a foot pedal simulation device.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a foot pedal simulation device, including a frame and four foot pedal assemblies. Two foot pedal assemblies are located in the driver's seat, and the other two are located in the passenger seat. A support shaft is fixedly mounted on the frame. The upper ends of the two foot pedal assemblies in the same driver's seat are rotatably connected by a connecting shaft. The two ends of the connecting shaft are fixedly connected to the support shaft by mounting cranks. A synchronous shaft is rotatably mounted on the frame and connected to a servo motor. Two differential cranks are fixedly mounted on the synchronous shaft at intervals along its axial direction. Each differential crank includes two staggered hinge parts, and each hinge part is hinged to a synchronous connecting rod. The synchronous shaft is connected to four sets of foot pedal assemblies via four synchronous connecting rods. The differential crank design allows adjacent synchronous connecting rods to have different tilt angles, thus controlling the linkage of the two foot pedal assemblies located on the left and right sides within the same driver's seat. Simultaneously, driven by the synchronous shaft, another differential crank, and two more synchronous connecting rods, the two sets of foot pedal assemblies in the other driver's seat perform the same actions synchronously, thereby achieving linkage within the same driver's seat and between two driver's seats. Furthermore, the servo motor-driven synchronous shaft not only simulates autonomous driving but also provides feedback force during manual pedaling simulation.

[0008] Preferably, each pedal assembly has a position adjustment crank on one side, which is rotatably mounted on an adjacent connecting shaft. The lower end of each pedal assembly is connected to the lower end of the position adjustment crank via a pedal position adjustment handle. The upper end of the position adjustment crank is hinged to an adjacent synchronizing link. The synchronizing shaft applies force to the corresponding position adjustment crank via the synchronizing link, which in turn applies force to the corresponding pedal assembly via the position adjustment crank, thereby driving the pedal assembly to move or providing feedback force.

[0009] Preferably, the lower end of the position adjustment crank is provided with several adjustment holes at intervals along the travel direction of the pedal assembly. The foot pedal position adjustment handle passes laterally through the lower end of the pedal assembly and is inserted into the corresponding adjustment hole. The position of the pedal assembly can be restricted by the cooperation between the foot pedal position adjustment handle and the position adjustment crank. When it is necessary to adjust the position of the pedal assembly, the foot pedal position adjustment handle can be pulled out, the pedal assembly can be adjusted into place, and then the foot pedal position adjustment handle can be reinserted. The travel range of the pedal assembly can be changed as needed to meet the needs of trainees of different heights.

[0010] Preferably, the adjustment holes are arranged at intervals along an arc-shaped trajectory to accommodate the overall position adjustment needs of the foot pedal assembly.

[0011] Preferably, the foot pedal assembly includes a foot pedal and a foot pedal bracket. The upper end of the foot pedal bracket is rotatably connected to a connecting shaft, and the lower end of the foot pedal bracket is rotatably connected to the lower end of the foot pedal via the foot pedal shaft. The foot pedal shaft has a hollow structure, and the foot pedal position adjustment handle passes through the inside of the foot pedal shaft. The overall structure is compact, and the position adjustment of the foot pedal assembly is convenient.

[0012] Preferably, a potentiometer is fixedly mounted on the crank, and a rotating crank is rotatably mounted on the connecting shaft. One end of the rotating crank is connected to the potentiometer via a push rod, and a brake spring is sleeved on the push rod. The other end of the rotating crank is connected to the lower end of the pedal via a potentiometer connecting rod. When the pedal is pressed, the potentiometer connecting rod is activated, which in turn activates the rotating crank. The rotating crank compresses the brake spring via the push rod and triggers the potentiometer. The potentiometer can be used to collect signals and feed them back to the server to detect the training simulation effect.

[0013] Preferably, a limiting crank is fixedly connected to one side of the potentiometer. The limiting crank has a limiting hole, which is an arc-shaped elongated hole. The rotating crank includes a connecting shaft, which is inserted into the limiting hole. The rotation angle of the rotating crank is limited by the cooperation between the connecting shaft and the limiting hole, thereby limiting the pedal stroke.

[0014] Preferably, the synchronous shaft is arranged horizontally, and both ends of the synchronous shaft are rotatably connected to the frame through bearing seats. The servo motor is fixedly mounted on the frame and connected to the synchronous shaft through a crank-connecting rod structure, which facilitates the arrangement of the servo motor position and improves the compactness of the overall structure. The servo motor drives the synchronous shaft to move, and the motion angle data of the foot pedal can be obtained through the position height precision encoder of the servo motor and fed back to the server, avoiding the angle data error caused by the installation error of the external sensor.

[0015] Preferably, the support shaft is higher than the synchronous rotating shaft, and the support shaft is located in front of the synchronous rotating shaft, so that the synchronous rotating shaft can drive the foot pedal assembly by using the inclined synchronous connecting rod.

[0016] This utility model provides a transport aircraft simulator that uses the aforementioned foot pedal simulation device.

[0017] As can be seen from the above technical solutions, the advantages of this utility model are:

[0018] 1. Two differential cranks are fixedly installed at axial intervals on the synchronous rotating shaft. The differential cranks include two staggered hinges, each hinge corresponding to a synchronous connecting rod, so that the tilt angles of adjacent synchronous connecting rods are different, thereby controlling the linkage of the two foot pedal components set on the left and right sides in the same driver's seat. At the same time, driven by the synchronous rotating shaft, the other differential crank, and the other two synchronous connecting rods, the two foot pedal components in the other driver's seat perform the same action synchronously, thereby realizing the linkage within the same driver's seat and between the two driver's seats. In addition, the servo motor driving the synchronous rotating shaft can not only simulate automatic driving, but also provide feedback force when simulating manual pedaling. Moreover, the single synchronous connecting rod forced constraint eliminates action delay and improves the simulation accuracy of the overall device.

[0019] 2. The lower end of the position adjustment crank is provided with several adjustment holes at intervals along the travel direction of the pedal assembly. The foot pedal position adjustment handle passes horizontally through the lower end of the pedal assembly and is inserted into the corresponding adjustment hole. The position of the pedal assembly can be restricted by the cooperation of the foot pedal position adjustment handle and the position adjustment crank. When it is necessary to adjust the position of the pedal assembly, the foot pedal position adjustment handle is pulled out, the pedal assembly is adjusted to the correct position, and then the foot pedal position adjustment handle is reinserted. The travel range of the pedal assembly can be changed as needed to meet the needs of trainees of different heights. Attached Figure Description

[0030] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0031] Example 1

[0032] In a typical embodiment of this utility model, such as Figures 1-7As shown, a foot pedal simulation device is proposed, including: a frame 1, a servo motor 4, a synchronous connecting rod 5, a synchronous rotating shaft 6, a support shaft 7, foot pedal components 8, a differential crank 20, and a connecting shaft 23. The synchronous rotating shaft 6 is laterally rotatable on the frame 1. The servo motor 4 is fixedly installed inside the frame 1 and connected to the synchronous rotating shaft 6 via a crank-connecting rod structure, thereby driving the synchronous rotating shaft 6 to rotate around its axis. The support shaft 7 is laterally fixedly installed on the frame 1, higher than the synchronous rotating shaft 6, and located in front of the synchronous rotating shaft 6. The support shaft 7 is used for mounting the foot pedal components 8. Four foot pedal components 8 are provided, corresponding to the four foot pedals 12 of the driver and co-pilot positions of the transport aircraft. Two foot pedal components 8 are provided for the driver's position, and the other two for the co-pilot position. The driver's seat is equipped with two foot pedal assemblies 8. The upper ends of the two foot pedal assemblies 8 at the same driver's seat are connected by a connecting shaft 23. The foot pedal assembly 8 and the connecting shaft 23 are rotatably connected. The two ends of the connecting shaft 23 are fixedly connected to the support shaft 7 by mounting cranks 17. There are two differential cranks 20. The two differential cranks 20 are fixedly mounted on the shaft of the synchronous shaft 6 so as to rotate synchronously around the shaft with the synchronous shaft 6. The differential crank 20 includes two hinge parts 201. The two hinge parts 201 are staggered. Specifically, the two hinge parts 201 are spaced apart along the axial direction of the synchronous shaft 6 and distributed vertically. Each hinge part 201 is hinged to a synchronous connecting rod 5, so that the four synchronous connecting rods 5 are respectively connected to the four foot pedal assemblies 8 to realize the linkage of the four foot pedal assemblies 8.

[0033] The differential crank 20 is configured such that the tilt angles of two adjacent synchronous connecting rods 5 (i.e., two synchronous connecting rods 5 located in the same driver's seat) are different (e.g., Figure 4 As shown, this allows control over the linkage of the two foot pedal components 8 positioned on the left and right sides within the same driver's seat. That is, when one foot pedal component 8 in the same driver's seat is in the depressed state, the other foot pedal component 8 in the same driver's seat is in the raised state. Simultaneously, driven by the synchronous shaft 6, another differential crank 20, and two other synchronous connecting rods 5, the two foot pedal components 8 in the other driver's seat perform the same actions synchronously, thereby achieving linkage within the same driver's seat and between the two driver's seats. In addition, the way the servo motor 4 drives the synchronous shaft 6 can not only simulate autonomous driving but also provide feedback force during manual pedaling simulation.

[0034] like Figure 2 , Figure 3 and Figure 5As shown, a bearing seat 19 is fixedly installed on the frame 1. Both ends of the synchronous rotating shaft 6 are fixedly connected to the bearing seat 19, thereby realizing the rotational connection between the synchronous rotating shaft 6 and the frame 1. The crank-connecting rod structure includes a connecting crank 2 and a driving connecting rod 3. The servo motor 4 is fixedly installed on the frame 1. One end of the connecting crank 2 is fixedly connected to the synchronous rotating shaft 6, and the other end of the connecting crank 2 is hinged to the output end of the servo motor 4 through the driving connecting rod 3. The servo motor 4 drives the synchronous rotating shaft 6 to rotate around the axis through the driving connecting rod 3 and the connecting crank 2. In the way the servo motor 4 drives the synchronous rotating shaft 6 to move, the motion angle data of the foot pedal 12 can be obtained by the position height precision encoder of the servo motor and fed back to the server, avoiding the angle data error caused by the installation error of the external sensor.

[0035] like Figure 1 As shown, each pedal assembly 8 has a position adjustment crank 13 on one side (left or right). The position adjustment crank 13 is rotatably mounted on the adjacent connecting shaft 23 via a bearing. The lower end of each pedal assembly 8 is connected to the lower end of the adjacent position adjustment crank 13 via a pedal position adjustment handle 9. The upper end of the position adjustment crank 13 is hinged to the adjacent synchronous connecting rod 5. Thus, when the synchronous shaft 6 rotates, it applies force to the corresponding position adjustment crank 13 through the synchronous connecting rod 5, and then applies force to the corresponding pedal assembly 8 through the position adjustment crank 13, so as to drive the pedal assembly 8 to move or provide feedback force.

[0036] The lower end of the position adjustment crank 13 is provided with a number of adjustment holes 131 at intervals along the travel direction (i.e., the direction of forward and backward movement) of the pedal assembly 8. The adjustment holes 131 are arranged at intervals along an arc-shaped trajectory. The foot pedal position adjustment handle 9 passes laterally through the lower end of the pedal assembly 8 and is inserted into the corresponding adjustment hole 131. Thus, the position of the pedal assembly 8 can be restricted by the cooperation between the foot pedal position adjustment handle 9 and the position adjustment crank 13. When it is necessary to adjust the position of the pedal assembly 8, the foot pedal position adjustment handle 9 is pulled out, the pedal assembly 8 is adjusted into place, and then the foot pedal position adjustment handle 9 is reinserted. The travel range of the pedal assembly 8 can be changed as needed to meet the needs of trainees of different heights.

[0037] Specifically, the pedal assembly 8 includes a pedal shaft 10, a pedal 12, and a pedal bracket 21. The upper end of the pedal bracket 21 is rotatably connected to the connecting shaft 23 via a bearing, and the lower end of the pedal bracket 21 is rotatably connected to the lower end of the pedal 12 via the pedal shaft 10. The pedal shaft 10 has a hollow structure, and the pedal position adjustment handle 9 passes through the inside of the pedal shaft 10 and connects to the adjustment hole 131 on the position adjustment crank 13 to limit the relative position of the pedal assembly 8 and the position adjustment crank 13.

[0038] In this embodiment, the foot pedal position adjustment handle 9 includes a handle portion and an insert rod portion. The handle portion and the insert rod portion are fixedly connected together. The insert rod portion is used to pass through the inside of the foot pedal shaft 10 and connect to the adjustment hole 131 on the position adjustment crank 13. The handle portion is convenient for trainees to pick up and operate, and also serves to limit the position of the insert rod portion.

[0039] A potentiometer 16 is fixedly mounted on the crank 17, and a rotating crank 18 is rotatably mounted on the connecting shaft 23. One end of the rotating crank 18 is connected to the potentiometer 16 via a push rod 22, and a brake spring 15 is sleeved on the push rod 22. The other end of the rotating crank 18 is connected to the lower end of the pedal 12 via a potentiometer connecting rod 11. Thus, when the pedal 12 is pressed, the potentiometer connecting rod 11 can be activated, which in turn activates the rotating crank 18. The rotating crank 18 compresses the brake spring 15 via the push rod 22 and triggers the potentiometer 16, so that the potentiometer 16 can collect signals and feed them back to the server to detect the training simulation effect.

[0040] Specifically, a connecting part 121 is fixedly provided on the lower front side of the foot pedal 12. The connecting part 121 is used to hinge with the lower end of the potentiometer connecting rod 11. The upper end of the potentiometer connecting rod 11 is hinged with the rotating crank 18, thereby driving the rotating crank 18 to rotate around the axis on the connecting shaft 23. The rotating crank 18 includes a push part 182, which is used to hinge with the push rod 22 to drive the push rod 22 to move. A stop part is fixedly provided on the push rod 22 to push and compress the brake spring 15. The brake spring 15 can not only provide feedback force when braking, but also play a self-resetting role.

[0041] To limit the travel of pedal 12, a limiting crank 14 is also provided, such as... Figure 6 As shown, the limiting crank 14 is provided with a limiting hole 141, which is an arc-shaped elongated hole. The limiting crank 14 is fixedly installed on the side of the potentiometer 16 away from the mounting crank 17. The rotating crank 18 also includes a connecting shaft 181, which is inserted into the limiting hole 141. The rotation angle of the rotating crank 18 is limited by the cooperation between the connecting shaft 181 and the limiting hole 141, thereby limiting the pedal stroke of the pedal 12.

[0042] Understandably, the push rod 22 has two directions of movement: when the pedal 12 is pressed backward to simulate braking, the push rod 22 moves backward to compress the brake spring 15 and trigger the potentiometer 16; when the entire pedal assembly 8 is pressed backward, the push rod 22 moves forward (away from the potentiometer 16).

[0043] The specific working principle is as follows:

[0044] When simulating autonomous driving, the servo motor 4 drives the four foot pedal components 8 to move synchronously through the synchronous shaft 6 and synchronous linkage 5. When the trainee simulates foot pedaling, the foot steps on the corresponding foot pedal component 8, and at the same time, the servo motor 4 provides feedback force to the corresponding foot pedal component 8 through the synchronous shaft 6, synchronous linkage 5, and position adjustment crank 13. Among them, the overall stepping on the foot pedal component 8 simulates directional control, and the individual stepping on the foot pedal 12 simulates braking.

[0045] When the position of the foot pedal 12 needs to be adjusted, simply pull out the foot pedal position adjustment handle 9, adjust the foot pedal assembly 8 into place, and then reinsert the foot pedal position adjustment handle 9. This allows the travel range of the foot pedal assembly 8 to be changed as needed to meet the needs of trainees of different heights.

[0046] Because the brake spring 15 has a large torque, when the pedal 12 is adjusted forward, the brake spring 15 will apply force to the pedal 12 through the push rod 22, causing the pedal 12 to rotate forward around the pedal pivot 10. This assists in adjusting the position of the pedal 12 without triggering the potentiometer 16 during the adjustment process. When the pedal 12 is adjusted backward, the brake spring 15 will not apply force to the pedal 12. The pedal 12 will rotate backward around the pedal pivot 10 under the action of gravity. The overall position adjustment of the pedal assembly 8, in conjunction with the adjustment of the pedal 12, can meet the actual needs with a small adjustment of the overall position of the pedal assembly 8.

[0047] Example 2

[0048] In another typical embodiment of this utility model, a transport aircraft simulator is proposed, which adopts the transport aircraft simulator described in Embodiment 1 to meet the usage needs of trainees of different heights, ensure the realism of the simulation, and improve the simulation training effect.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
