Description

Technical Field

[0001] This application relates to the field of flight simulation technology, and in particular to a force feedback base and a flight simulator. Background Technology

[0002] The quality of the motor wiring harness connections and the way it is secured on a flight simulator can affect the stability, accuracy, and even safety of signal transmission. Loose wiring harnesses can cause signal interference during transmission, affecting the flight simulator's response speed and accuracy, preventing pilots from obtaining a realistic flight experience during training; they can also easily cause short circuits or overheating; exposed or loose wiring harnesses increase the risk of accidental electric shock, posing a threat to operator safety; in extreme cases, they may even cause serious safety accidents such as fires. Furthermore, improper wiring harness routing and securing methods can lead to problems such as insufficient product space, messy wiring harnesses, and susceptibility to collisions and pulling, resulting in the aforementioned issues. Therefore, ensuring proper securing of the motor wiring harness is crucial to ensuring the normal operation of the flight simulator.

[0003] Currently, the conductive wires between the motor and the motherboard on the suspension shaft of the force feedback base of the flight simulator are prone to poor contact due to the swing of the suspension shaft itself, which can easily lead to malfunctions. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a force feedback base and a flight simulator.

[0005] In a first aspect, this application provides a force feedback base, comprising:

[0006] The first upright plate and the second upright plate are arranged opposite each other and at intervals;

[0007] The suspension axle is rotatably connected between the first and second vertical plates;

[0008] The motherboard has a first connector.

[0009] The first motor is mounted on the suspension axle;

[0010] A first conductive wire is connected between a first motor and a first connector, and the first conductive wire includes at least a first connecting segment;

[0011] The first clamp fixes one end of the first connecting segment to the first upright plate, and the other end of the first connecting segment is connected to the first plug interface.

[0012] Therefore, in this application, the first motor and the first connector on the motherboard need to be connected by a first conductive line to achieve signal transmission. The first conductive line is connected between the first motor and the first connector. The first conductive line includes at least a first connecting segment. A first clamp fixes one end of the first connecting segment to the first upright plate, and the other end of the first connecting segment is connected to the first connector. This can prevent the swing of the suspension axle from affecting the stability of the connection between the first conductive line and the first connector. Moreover, the first connecting segment is firmly fixed, and the structure is compact. This can avoid the additional space required due to the wiring problem of the first connecting segment, which would lead to an increase in the size of the force feedback base. It also prevents collisions and squeezing between the first connecting segment and the suspension axle.

[0013] In some possible embodiments of the first aspect, the first conductive wire further includes a second connecting segment, one end of which is connected to the first motor. The second connecting segment extends from the outer surface of the suspension axle to connect with the first connecting segment. The force feedback base further includes at least one second clamp, which fixes the second connecting segment to the outer surface of the suspension axle.

[0014] Therefore, in this application, the connection of the first conductive wire to the second connecting segment of the first motor can be fixed, which can prevent the rotation of the first motor from causing the second connecting segment to swing, thereby preventing poor contact between the first motor and the second connecting segment and improving the connection stability of the first conductive wire.

[0015] In some possible embodiments of the first aspect, the suspension axle is provided with a through hole penetrating a first side and a second side of the suspension axle, and a second connecting segment is disposed in the through hole such that a first conductive wire extends from the first side of the suspension axle to the second side of the suspension axle to connect with the first connecting segment.

[0016] Therefore, in this application, by passing the second connecting section through the through hole in the suspension axle along the front-rear direction, the length of the first conductive wire can be shortened, and the first conductive wire can be prevented from touching the inner surface of the housing, thus preventing the first conductive wire from being worn.

[0017] In some possible embodiments of the first aspect, the first conductive wire further includes a third connecting segment connected to one end of the first connecting segment and extending along the surface of the first upright plate from a first side of the suspension axle to a second side of the suspension axle to connect with the second connecting segment. The force feedback base further includes a third clamp fixed to the end of the third connecting segment connected to the second connecting segment.

[0018] Therefore, in this application, the third connecting segment is connected to one end of the first connecting segment and extends along the surface of the first vertical plate from the first side of the suspension shaft to the second side of the suspension shaft before connecting to the second connecting segment. This can prevent the third connecting segment from getting tangled, pulled, or worn due to the swing of the suspension shaft, and further improve the connection stability between the first connecting line, the first plug interface, and the first motor.

[0019] In some possible embodiments of the first aspect, a first groove is provided on the bottom end of the side of the suspension axle facing the first upright plate, and a third connecting segment passes through the first groove to extend from the first side of the suspension axle to the second side of the suspension axle.

[0020] Therefore, in this application, the first groove can increase the through-hole space between the first upright plate and the suspension shaft, making it easier for the third connecting section to pass through, and can prevent the suspension shaft from swinging and causing the third connecting section to get tangled, pulled or worn, further improving the connection stability between the first connecting line and the first plug interface and the first motor.

[0021] In some possible embodiments of the first aspect, the suspension axle includes a first side plate, a second side plate, a first panel and a second panel, the first side plate and the second side plate are arranged parallel and opposite to each other, the first panel and the second panel are arranged parallel and opposite to each other, the first side plate, the first panel, the second side plate and the second panel enclose a through space with openings at the top and bottom, the first motor is disposed in the through space, and the second connecting segment of the first conductive wire is fixed to the outer surface of the first panel and the second panel.

[0022] Therefore, in this application, the suspension axle has a square structure with openings at the top and bottom, which allows the first motor to be fixed inside the suspension axle and the second connecting section of the first conductive wire to be fixed to the outer surfaces of the first and second panels of the suspension axle, without interfering with each other and improving connection stability.

[0023] In some possible embodiments of the first aspect, the motherboard is provided with a second connector, and the force feedback base further includes a second motor, a second conductive wire and a fourth wire clamp. The second motor is fixed to the side of the first upright plate opposite to the second upright plate. One end of the second conductive wire is connected to the second motor, and the other end of the second conductive wire passes through the second upright plate and is connected to the second connector. The fourth wire clamp fixes the second conductive wire to the side of the first upright plate facing the second upright plate.

[0024] Therefore, in this application, the second conductive wire connecting the second motor and the second connector can be fixed to the side of the first upright plate facing the second upright plate by the fourth wire clamp, which can avoid the suspension shaft, prevent the swing of the suspension shaft from affecting the connection stability of the second conductive wire, and prevent the rotation of the second gear set from affecting the second conductive wire.

[0025] In some possible embodiments of the first aspect, the wire clamp includes a wire clamp fixing part and a wire harness fixing part, the wire harness fixing part protruding a predetermined height relative to the wire clamp fixing part.

[0026] Therefore, in this application, the wire harness fixing part protrudes a predetermined height relative to the wire clamp fixing part, which can increase the height between the wire harness (first conductive wire or second conductive wire) fixed on the wire clamp fixing part and the carrier (first upright plate or outer surface of suspension shaft) of the fixed wire clamp fixing part, avoid interference between the moving parts (e.g., transmission gear set) on the carrier and the wire harness (first conductive wire or second conductive wire), and improve the fixing effect and connection stability.

[0027] In some possible embodiments of the first aspect, the wire clamp fixing part and the wire harness fixing part are arranged along a first direction, and the wire harness fixing part is provided with a through hole along a second direction, the second direction intersecting or perpendicular to the first direction.

[0028] Therefore, in this application, the wire harness fixing part is provided with through holes along the second direction, which can ensure that the thickness of the wire clamp is uniform in each part, avoid shrinkage of the wire clamp during injection molding, reduce the weight of the wire clamp, reduce material usage, facilitate airflow, and help dissipate heat.

[0029] Secondly, this application provides a flight simulator, which includes the force feedback base of the first aspect.

[0030] The beneficial effects of the flight simulator in the second aspect are the same as those of the force feedback base in the first aspect, and will not be elaborated further. Attached Figure Description

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0054] In the description of this application, the terms "first," "second," etc. are used to distinguish different objects, rather than to describe a specific order. The terms "upper," "lower," "inner," "outer," etc., which indicate the orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0055] In the description of this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal connection of two components; it can be a communication connection; or it can be an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0056] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the modules of the flight simulator 1000 in this application embodiment. The flight simulator 1000 includes a simulated cockpit 1001, a motion system 1002, a visual system 1003, a computer system 1004, and auxiliary equipment 1005.

[0057] The simulator cockpit 1001 includes control units, instruments, and other equipment. The control units, including the joystick, throttle, rudder pedals, and force feedback base 100, are similar to those of a real aircraft, allowing players to perform takeoff, climb, turn, and landing maneuvers, simulating realistic flight control. The force feedback base 100 is the core component of the control unit, responsible for providing realistic control force feedback, simulating stick force, control surface drag, and abnormal conditions (such as stall, hydraulic failure, etc.) under different flight conditions. Instruments include an airspeed indicator, altimeter, localizer, attitude indicator, turn coordination indicator, and vertical speedometer, displaying information such as flight speed, altitude, direction, and attitude to help players understand the aircraft's flight status. Other equipment includes a seat and control panel. The seat is adjustable to simulate the physical sensations under different flight attitudes, and the control panel is used to control various flight systems and equipment.

[0058] The motion system 1002 includes a drive unit. The drive unit uses a hydraulic servo actuator or an electric actuator. By controlling the extension and retraction of the actuator, it drives the simulated cockpit 1001 to move, achieving 3-DOF or 6-DOF motion, allowing the player's body to feel the aircraft's movement changes. The 3-DOF includes pitch, roll, and yaw, enabling pitch, roll, and yaw movements, allowing the player to feel the aircraft's pitch, roll, and yaw. The 6-DOF, in addition to the 3-DOF, adds linear displacement in the forward, backward, left, right, and up / down directions, more realistically simulating various aircraft motion states in the air.

[0059] The visual system 1003 includes image generation and display devices. Image generation utilizes computer graphics technology to generate realistic 3D scenes and images based on calculations from flight simulation software. These include terrain, buildings, clouds, weather effects, and can simulate different weather conditions such as day / night cycles, sunny days, rainy days, and foggy days. Display devices include projectors, large-screen displays, or VR (Virtual Reality) headsets to display the generated images, providing players with a wide field of view and showcasing the external scenery of the aircraft, such as airports, runways, cities, mountains, and oceans, making players feel as if they are in a realistic flight environment.

[0060] Computer system 1004 includes hardware and flight simulation software. The hardware includes one or more high-performance computers to meet the operational requirements of the flight simulation software, processing large amounts of flight data and handling graphics rendering tasks. The flight simulation software contains mathematical models, aerodynamic models, and flight control system models of the aircraft. Based on the player's actions and flight status, it calculates the aircraft's trajectory, attitude changes, instrument data, etc., in real time and feeds the results back to other systems, achieving real-time performance and accuracy in flight simulation.

[0061] Auxiliary equipment 1005 includes an audio system and a lighting system. The audio system includes speakers or headphones that play sounds such as the roar of the aircraft engine, wind noise, landing gear retraction and extension sounds, and communication sounds, enhancing the realism and immersion of the flight and making the player feel more present. The lighting system simulates the lighting effects inside the aircraft cockpit, such as instrument lights, cabin lighting, and signal lights, as well as external airport lights and runway lights. It adjusts according to flight status and environmental changes, providing the player with a more realistic visual experience.

[0062] Please refer to Figure 2 , Figure 2 This is a three-dimensional structural diagram of the force feedback base 100 according to an embodiment of this application. For ease of description, the following definitions are used. Figure 2 The front-to-back direction of the force feedback base 100 shown is the Y-axis direction, i.e., the thickness direction and the front-to-back direction, defined as follows: Figure 2 The left and right directions of the force feedback base 100 shown are the X-axis directions, i.e., the length direction and the horizontal direction, defined as follows: Figure 2 The height direction of the force feedback base 100 shown is the Z-axis direction, vertical direction. The directional terms such as "top," "bottom," "left," and "right" used in the description of the force feedback base 100 in this application are based on the accompanying drawings. Figure 2 The description of the orientation shown, with the positive direction of the Z-axis as "top", the negative direction of the Z-axis as "bottom", the negative direction of the X-axis as "left", the positive direction of the X-axis as "right", the negative direction of the Y-axis as "back", and the positive direction of the Y-axis as "front", does not constitute a limitation on the force feedback base 100 in actual application scenarios.

[0063] like Figure 2 As shown, the force feedback base 100 includes a housing 10. The housing 10 includes a first upright plate 12, a second upright plate 13, and a base plate 14. The first upright plate 12 and the second upright plate 13 are positioned opposite each other and spaced apart. The base plate 14 is connected to the bottom ends of the first upright plate 12 and the second upright plate 13. The first upright plate 12, the second upright plate 13, and the base plate 14 together form a receiving space 11. It is understood that... Figure 2 Only the first upright plate 12, the second upright plate 13, and the bottom plate 14 of the housing 10 are shown. In reality, the housing 10 may include a front panel, a rear panel, and a top panel, thereby forming a relatively well-sealed receiving space 11, which can improve the airtightness of the housing 10.

[0064] The force feedback base 100 also includes a suspension shaft 41. The suspension shaft 41 is rotatably connected between the first upright plate 12 and the second upright plate 13 and is located on the base plate 14. Specifically, the suspension shaft 41 includes a first side plate 411, a second side plate 412, a first panel 413, and a second panel 414. The first side plate 411 and the second side plate 412 are arranged opposite to each other and parallel to each other. The first panel 413 and the second panel 414 are arranged parallel to each other and opposite to each other. The first side plate 411, the first panel 413, the second side plate 412, and the second panel 414 enclose a through space 415 with openings at the top and bottom. The first upright plate 12 and the second upright plate 13 are located on the left and right sides of the suspension shaft 41, respectively. The first side plate 411 is arranged corresponding to the first upright plate 12, and the second side plate 412 is arranged corresponding to the second upright plate 13. Therefore, when the suspension shaft 41 is rotatably connected to the first upright plate 12 and the second upright plate 13, it can rotate around the X-axis. The suspension axle 41 includes a first side 41a and a second side 41b arranged opposite to each other. The first side 41a is located at the front of the suspension axle 41, and the second side 41b is located at the rear of the suspension axle 41. When the suspension axle 41 swings forward, it swings toward the first side 41a, and when it swings backward, it swings toward the second side 41b.

[0065] The upper surfaces of the first panel 413 and the second panel 414 are flush, and the lower surface of the first panel 413 is lower than the lower surface of the second panel 414. The first panel 413 is provided with a first through hole 4131. The force feedback base 100 also includes a first motor assembly 44. The first motor assembly 44 includes a first motor 441, a first flange, a first output shaft 442, and a first magnet. The first motor 441 is located in the through space 415 and fixed to the first panel 413, and the second panel 414 is provided with a fitting structure suitable for the first motor 441 to further fix the first motor 441. The first flange is connected to the first motor 441 and fits with the first through hole 4131. The first flange is provided with a first shaft hole. One end of the first output shaft 442 is connected to the first motor 441, and the other end passes through the first shaft hole to realize kinetic energy output in the first direction. The first magnet is located at the end of the first output shaft 442. The first direction is parallel to the Y-axis direction.

[0066] The force feedback base 100 also includes a first magnetic encoder plate (not shown), which is disposed on the side of the first magnet away from the first panel 413 to measure the rotation angle of the first output shaft 442.

[0067] The force feedback base 100 also includes a first gear set 43, which includes a first pinion 431 and a first gear 432. The first pinion 431 is connected to the first output shaft 442, and the first gear 432 meshes with the first pinion 431 and is also arranged parallel to the first panel 413.

[0068] In this embodiment, to make the force feedback base 100 structure more compact, the first pinion 431 is a cylindrical gear and the first large gear 432 is a sector gear. Preferably, the first pinion 431 and the first large gear 432 are helical gears, which can significantly reduce vibration and noise and reduce instantaneous impact. In other embodiments, the first pinion 431 and the first large gear 432 can be cylindrical gears or other types of gears, which are not limited here.

[0069] The force feedback base 100 also includes a handle shaft 50 and a connecting shaft 60. The first panel 413 and the second panel 414 are respectively provided with a first shaft groove 4132 and a second shaft groove 4141 at positions corresponding to the rotation of the first large gear 432. One end of the handle shaft 50 extends into the through space 415 of the suspension shaft 41, and the other end extends upwards. The connecting shaft 60 connects the shaft hole of the first large gear 432, the first shaft groove 4132, the shaft hole of the handle shaft 50, and the second shaft groove 4141, achieving a fixed connection between the first large gear 432, the connecting shaft 60, and the handle shaft 50. This enables the handle shaft 50 to rotate relative to the suspension shaft 41, and the through spaces 415 on the left and right sides of the suspension shaft 41 provide sliding space for the left and right swinging of the handle shaft 50.

[0070] The force feedback base 100 also includes a second motor assembly 20. A second through hole 121 is provided on the first upright plate 12. The second motor assembly 20 includes a second motor 21, a second flange 24, a second output shaft, and a second magnet. The second motor 21 is located on the side of the first upright plate 12 opposite to the second upright plate 13. The second flange 24 is connected to the side of the second motor 21 connected to the second output shaft, and the second flange 24 mates with the second through hole 121. A second shaft hole is provided on the second flange 24. One end of the second output shaft is connected to the second motor 21, and the other end passes through the second shaft hole, realizing kinetic energy output in a second direction, which is parallel to the X-axis direction.

[0071] The force feedback base 100 also includes a second magnetic encoder plate, which is located on the side of the second magnet opposite to the first upright plate 12 to measure the rotation angle of the second output shaft.

[0072] The force feedback base 100 also includes a second gear set 42, which includes a second pinion 421 and a second large gear 422. The second pinion 421 is connected to the second output shaft, and the second large gear 422 meshes with the second pinion 421. The surface of the second large gear 422 is parallel to the first vertical plate 12, and the second large gear 422 is located between the first vertical plate 12 and the first side plate 411. The second large gear 422 and the first vertical plate 12 are rotatably connected, and the second large gear 422 and the first side plate 411 are fixedly connected. In addition, the second side plate 412 and the second vertical plate 13 are also rotatably connected.

[0073] In this embodiment, to make the force feedback base 100 structure more compact, the second pinion 421 is a cylindrical gear, and the second large gear 422 is a sector gear. Preferably, the second pinion 421 and the second large gear 422 are helical gears, which can significantly reduce vibration and noise and reduce instantaneous impact. In other embodiments, the second pinion 421 and the second large gear 422 can be cylindrical gears or other types of gears, which are not limited here.

[0074] The force feedback base 100 also includes a main board 90, which is mounted on the base plate 14 and located between the first upright plate 12 and the second upright plate 13, and below the suspension shaft 41. The main board 90 has a first connector 901 and a second connector 902 on its front side.

[0075] The force feedback base 100 also includes a first conductive line 70, which is connected between the first motor 441 and the first plug-in interface 901, and a second conductive line 80, which is connected between the second motor 21 and the second plug-in interface 902.

[0076] It should be noted that the connection stability of the wiring harness (e.g., the first conductive line 70 or the second conductive line 80) directly affects the operational reliability of the force feedback base. Therefore, the focus of this application is to protect a wiring harness layout structure for a force feedback base to improve wiring harness stability. The wiring harness layout structure of the force feedback base will be described below using force feedback base 100 as an example. In practice, force feedback bases suitable for wiring harness layout structures can have more or fewer structural components than the aforementioned force feedback base 100, or other types of force feedback bases 100, which are not limited here.

[0077] It was discovered that the swing of the aforementioned suspension axle 41 could easily lead to poor contact between the first conductive wire 70 and the first connector 901.

[0078] In view of this, this application provides a force feedback base 100, the force feedback base 100 comprising:

[0079] The first upright plate 12 and the second upright plate 13 are arranged opposite to each other and at intervals.

[0080] Suspension axle 41 is rotatably connected between the first vertical plate 12 and the second vertical plate 13;

[0081] Motherboard 90, with a first connector 901 on motherboard 90;

[0082] The first motor 441 is mounted on the suspension axle 41;

[0083] The first conductive line 70 is connected between the first motor 441 and the first plug-in interface 901, and the first conductive line 70 includes at least a first connecting segment 73;

[0084] The first wire clamp 65 fixes one end of the first connecting segment 73 to the first upright plate 12, and the other end of the first connecting segment 73 is connected to the first plug interface 901.

[0085] Therefore, in this application, the first conductive wire 70 is connected between the first motor 441 and the first plug-in interface 901, and the first wire clamp 65 fixes one end of the first connecting segment 73 to the first upright plate 12, while the other end of the first connecting segment 73 is connected to the first plug-in interface 901. This can prevent the swing of the suspension shaft 41 from affecting the stability of the connection between the first conductive wire 70 and the first plug-in interface 901, and the first connecting segment 73 is thus firmly fixed. The structure is compact, which can avoid the additional space required due to the wiring problem of the first connecting segment 73, thus avoiding the increase in the structural size of the force feedback base 100. It also prevents the first connecting segment 73 from colliding or being squeezed with the suspension shaft 41.

[0086] In some embodiments, the first clamp 65 is located near the second pinion 421 and the second gear 422, below them.

[0087] Therefore, in this application, when the first connecting segment 73 is fixed to the first clamp 65, the first clamp 65 can fix the first connecting segment 73 below the second pinion 421 and the second gear 422, so as to avoid the influence of the rotation of the second gear 422 on the first connecting segment 73.

[0088] In some embodiments, the first conductive line 70 further includes a second connecting segment 72, one end of which is connected to the first motor 441. The second connecting segment 72 extends from the outer surface of the suspension shaft 41 to connect with the first connecting segment 73. The force feedback base 100 also includes at least one second clamp 61, which fixes the second connecting segment 72 to the outer surface of the suspension shaft 41.

[0089] Therefore, in this application, at least one second clamp 61 can fix the second connecting segment 72, preventing the rotation of the first motor 441 and the swing of the suspension shaft 41 from causing the second connecting segment 72 to move, thereby causing poor contact between the first motor 441 and the second connecting segment 72, and improving the connection stability between the first conductive wire 70 and the first motor 441.

[0090] In some embodiments, please refer to the following: Figure 2 , Figure 3 and Figure 4 The suspension axle 41 includes a first side 41a and a second side 41b disposed opposite to each other. The first side 41a is located at the front of the suspension axle 41, and the second side 41b is located at the rear of the suspension axle 41. When the suspension axle 41 can rotate about the X-axis, it can swing forward (towards the first side 41a) and swing backward (towards the second side 41b). The second connecting segment 72 extends from the bottom end of the first side 41a of the suspension axle 41 towards the top end of the suspension axle 41. When it reaches the second side 41b, it extends laterally from the side of the second side 41b adjacent to the second upright plate 13 to the side adjacent to the first upright plate 12, and extends downward to connect with the first connecting segment 73 fixed to the first upright plate 12. In other embodiments, the second connecting segment 72 may extend on the first side 41a and connect with the first connecting segment 73.

[0091] In some embodiments, the portion of the second connecting segment 72 located on the surface of the first side 41a of the suspension axle 41 extends from the lower opening of the through space 415 and bends to extend from the bottom end of the first panel 413 to the top end of the first panel 413 and is positioned along the right edge adjacent to the suspension axle 41. The first second clamp 61 is positioned adjacent to the top end and right side of the first panel 413, which can tighten and straighten the portion of the second connecting segment 72 located on the surface of the first side 41a of the suspension axle 41. This prevents the vibration caused by the swing of the suspension axle 41 and the rotation of the first motor 441 from shifting the portion of the second connecting segment 72 located on the surface of the first side 41a of the suspension axle 41 to a position closer to the output shaft of the first motor 441, thereby improving the stability and reliability of system operation and reducing wear on the cable of the second connecting segment 72 caused by the movement of the second connecting segment 72 relative to the first panel 413.

[0092] In some embodiments, please refer to Figure 4 and Figure 5 The portion of the second connecting section 72 located on the surface of the second side 41b of the suspension axle 41 is generally transversely positioned, passing between the second axle groove 4141 and the limiting groove 4142, and then extending downward to connect with the first connecting section 73 fixed to the first upright plate 12. A second second clamp 61 is located near the second upright plate 13 on the second side 41b of the suspension axle 41, and a third second clamp 61 is located near the first upright plate 12 on the second side 41b of the suspension axle 41. The second and third second clamps 61 respectively fix the portions of the second connecting section 72 located on the surface of the second side 41b of the suspension axle 41 at both ends. Therefore, the second second clamp 61 is located on one side of the second shaft groove 4141 and the limiting groove 4142, and the third second clamp 61 is located on the other side of the second shaft groove 4141 and the limiting groove 4142. This allows for the fixation of the portion of the second connecting section 72 located on the second side 41b of the suspension shaft 41 on the opposite sides of the second shaft groove 4141 and the limiting groove 4142, resulting in a better fixing effect.

[0093] In some embodiments, please refer to Figure 2 and Figure 4The suspension axle 41 has a through hole 418 penetrating the first side 41a and the second side 41b. The second connecting section 72 passes through the through hole 418, extending from the first side 41a to the second side 41b. Specifically, the first panel 413 has a first through hole 4181, and the second panel 414 has a second through hole 4182. The first through hole 4181 and the second through hole 4182 are spaced apart and opposite to each other, and together they form the aforementioned through hole 418. Viewed from the front of the force feedback base 100, the first second clamp 61 is located adjacent to the right side of the through hole 418. Viewed from the rear of the force feedback base 100, the second second clamp 61 is located adjacent to the right side of the through hole 418, allowing the second connecting section 72 to be fixed in accordance with its direction of travel.

[0094] Therefore, in this application, by passing the second connecting segment 72 through the through hole 418 that runs through the suspension shaft 41 in the front-rear direction, the length of the second connecting segment 72 can be shortened, and the second connecting segment 72 can be prevented from hitting the inner surface of the housing 10, thus preventing the second connecting segment 72 from being worn.

[0095] In some embodiments, the suspension axle 41 includes a first side plate 411, a second side plate 412, a first panel 413, and a second panel 414. The first side plate 411 and the second side plate 412 are arranged opposite to each other and parallel to each other. The first panel 413 and the second panel 414 are arranged parallel to each other and opposite to each other. The first side plate 411, the first panel 413, the second side plate 412, and the second panel 414 enclose a through space 415 with openings at the top and bottom. The first motor 441 is fixed inside the suspension axle 41, and the second connecting segment 72 of the first conductive wire 70 is fixed to the outer surface of the first panel 413 and the second panel 414.

[0096] Therefore, in this application, the suspension shaft 41 has a square structure with openings at the top and bottom, which can fix the first motor 441 inside the suspension shaft 41 and fix the first conductive wire 70 to the outer surface of the first panel 413 and the second panel 414 of the suspension shaft 41 without interfering with each other, thus improving the connection stability.

[0097] In some embodiments, the first conductive line 70 further includes a third connecting segment 74, which is connected to one end of the first connecting segment 73 and extends along the surface of the first upright plate 12 from the first side 41a of the suspension shaft 41 to the second side 41b of the suspension shaft 41 before connecting to the second connecting segment 72. The force feedback base 100 also includes a third wire clamp 64, which is fixed to the end of the third connecting segment 74 connected to the second connecting segment 72.

[0098] Therefore, in this application, the third cable clamp 64 is located behind the first cable clamp 65 and is at approximately the same height as the first cable clamp 65, and maintains a certain distance from the surface of the second side 41b of the suspension axle 41. In this way, the position where the second connecting section 72 is connected to the third connecting section 74 will maintain a certain distance from the suspension axle 41, and the swing of the suspension axle 41 will not touch the second connecting section 72, which can improve the connection stability.

[0099] When the first conductive wire 70 is directly connected to the first connector 901 on the motherboard 90 on the first side 41a of the suspension shaft 41, the distance between the end of the first conductive wire 70 connected to the first motor 441 and the first connector 901 is too close. The swing of the suspension shaft 41 around the first direction will cause poor contact between the first conductive wire 70 and the first connector 901. In this application, the first connector 901 is located on the first side 41a of the suspension shaft 41; one end of the first conductive wire 70 is connected to the first motor 441 on the first side 41a, and the other end of the first conductive wire 70 extends from the first side 41a of the suspension shaft 41 along the suspension shaft 41 itself to the second side 41b, and then extends from the second side 41b along the gap between the first upright plate 12 and the suspension shaft 41 to the first side 41a to connect to the first connector 901. This optimized wiring method can avoid the swing of the suspension shaft 41 from affecting the stability of the connection between the first conductive wire 70 and the first connector 901. The wire harness connection is firm, the cost is low, the assembly is simple, and the structure is compact. It can avoid the additional space required due to wire harness wiring problems, which would lead to an increase in the product structure size. There will be no wire harness collision or squeezing.

[0100] It should be noted that the first connecting segment 73 is the portion of the first conductive wire 70 between the first plug-in interface 901 and the first wire clamp 65; the second connecting segment 72 is the portion of the first conductive wire 70 between the first motor 441 and the third wire clamp 64; and the third connecting segment 74 is the portion of the first conductive wire 70 between the first wire clamp 65 and the third wire clamp 64. This is understandable. Figure 2 , Figure 3 and Figure 4 This is merely an illustration of the first connecting segment 73, the second connecting segment 72, and the third connecting segment 74. In reality, the first conductive line 70 can be a single, continuous conductive line. In other embodiments, the first connecting segment 73, the second connecting segment 72, and the third connecting segment 74 can be segmented conductive lines with adjacent ends connected together by connectors.

[0101] Therefore, in this application, by conforming to the external structure of the suspension axle 41, the first conductive wire 70 is fixed in segments, which improves the fixing effect of the first conductive wire 70. Moreover, since the end of the second connecting segment 72 connected to the third connecting segment 74 spans between the surface of the second side 41b of the suspension axle 41 and the inner surface of the first upright plate 12, and considering the swing amplitude of the suspension axle 41, a certain amount of movement can be left to avoid the second connecting segment 72 being pulled when the suspension axle 41 swings, which can further improve the connection stability.

[0102] In some embodiments, please refer to Figure 3 and Figure 5 A first groove 419 is provided on the bottom end of the suspension axle 41 facing the first upright plate 12, and the third connecting section 74 passes through the first groove 419 to extend from the first side 41a of the suspension axle 41 to the second side 41b of the suspension axle 41.

[0103] Therefore, in this application, the through hole size between the first upright plate 12 and the suspension shaft 41 can be increased through the first groove 419, which facilitates the passage of the third connecting section 74 and can prevent the swing of the suspension shaft 41 from causing the third connecting section 74 to become entangled, pulled or worn, and further improve the connection stability between the first conductive wire 70 and the first plug interface 901 and the first motor 441.

[0104] In some embodiments, please continue to refer to Figure 2 The force feedback base 100 also includes a second motor 21 and a second conductive wire 80. The second motor 21 is fixed to the side of the first upright plate 12 facing away from the second upright plate 13. One end of the second conductive wire 80 is connected to the second motor 21, and the other end of the second conductive wire 80 passes through the second upright plate 13 and is connected to the second connector 902 located on the main board 90. A fourth wire clip 66 fixes the second conductive wire 80 to the side of the first upright plate 12 facing the second upright plate 13.

[0105] It is understandable that the second vertical plate 13 may be provided with a wire hole through which the second conductive wire 80 passes.

[0106] Therefore, in this application, the second conductive wire 80 connected between the second motor 21 and the second plug interface 902 can be fixed to the side of the first upright plate 12 facing the second upright plate 13 by the fourth wire clamp 66, which can avoid the suspension shaft 41 and prevent the swing of the suspension shaft 41 and the rotation of the second gear set 42 from affecting the connection stability of the second conductive wire 80.

[0107] Please refer to Figure 6 , Figure 6This is a schematic diagram of the wire clamp 200 in the embodiments of this application. The wire clamp 200 can be the aforementioned first wire clamp 65, second wire clamp 61, third wire clamp 64, or fourth wire clamp 66. The wire clamp 200 includes a wire clamp fixing part 201 and a wire harness fixing part 202, with the wire harness fixing part 202 protruding a predetermined height relative to the wire clamp fixing part 201.

[0108] Therefore, in this application, the wire harness fixing part 202 protrudes a predetermined height relative to the wire clamp fixing part 201, which can increase the height between the wire harness (first conductive wire 70 or second conductive wire 80) fixed on the wire clamp fixing part 201 and the carrier (first upright plate 12 or outer surface of suspension shaft 41) of the fixed wire clamp fixing part 201, avoid interference between the moving parts (e.g., transmission gear set) provided on the carrier and the wire harness, and improve the fixing effect and connection stability.

[0109] In some embodiments, the wire clamp fixing part 201 and the wire harness fixing part 202 are arranged along a first direction, and the wire harness fixing part 202 is provided with a through hole 203 along a second direction, which intersects or is perpendicular to the second direction.

[0110] The first direction can be the length direction of the wire clamp 200, and the second direction can be the width direction of the wire clamp 200.

[0111] Therefore, in this application, the wire harness fixing part 202 is provided with a through hole 203 along the second direction, which can ensure that the thickness of the wire clamp 200 is uniform in each part, avoid the wire clamp 200 shrinking during injection molding, reduce the weight of the wire clamp 200, reduce the amount of material used, facilitate airflow, and help dissipate heat.

[0112] In some embodiments, the clamp fixing part 201 is flat and has a screw hole for the threaded connector to pass through to fix the clamp 200 to the carrier.

[0113] In some embodiments, the wire harness fixing part 202 has an I-beam portion on one side of the through hole 203, and the binding strap can pass through the through hole 203 to bind the wire harness to the I-beam portion.
