Description

Technical Field

[0001] This application relates to the field of control handle technology, and in particular to control handles and simulators. Background Technology

[0002] The connection between the base axis and the joystick axis in the simulator is the core mechanical structure for building a highly realistic and immersive simulation experience. The base axis provides a powerful force feedback source and a precise transmission or sensing structure, while the joystick axis is the part that the user directly contacts and applies operating force to. The connection between the two is the key to ensuring accurate transmission of input commands and realistic reproduction of force feedback.

[0003] Currently, the connection between the base shaft and the joystick shaft is mostly made by using nuts for threaded connection. This type of connection is prone to loosening when the joystick shaft is subjected to large torque input, and the looseness or lag between the base shaft and the joystick shaft will affect the realism and accuracy of the simulation. Utility Model Content

[0004] Therefore, it is necessary to provide a control handle and simulator to address the problem that the traditional connection between the base shaft and the joystick shaft, which mostly uses nuts for threaded connections, is prone to loosening when the joystick shaft is subjected to high torque.

[0005] In a first aspect, embodiments of this application provide a control handle, the control handle comprising:

[0006] Base, with base shaft;

[0007] joystick;

[0008] A connector is detachably connected to the base shaft, the base shaft and the connector form a fixed position, the end of the control lever is disposed at the fixed position, and the connector is configured to connect to the base shaft to limit the control lever to the fixed position;

[0009] An anti-loosening component is provided on the connector, one end of which abuts against the end of the control lever. The anti-loosening component is configured to apply force to the control lever along the axial direction of the control lever so that the control lever continuously abuts against the base shaft.

[0010] This embodiment places the end of the control lever in a fixed position formed by the base shaft and the connector, and limits the control lever through the cooperation of the base shaft and the connector, thus achieving a single fixation of the control lever, the connector, and the base shaft. Simultaneously, by applying force along the axial direction of the control lever through the anti-loosening component, end-face friction is generated through hard contact with the end face of the control lever, while also eliminating the assembly gap between the base shaft and the connector. This achieves double fixation of the control lever and the base shaft, improving torsional strength and ensuring real-time transmission of force feedback between the control lever and the base shaft, reducing or eliminating looseness or lag between the base shaft and the control lever.

[0011] In one embodiment, the connector includes a body having a mounting groove and a mounting through hole at the bottom of the mounting groove. A portion of the base shaft is mounted in the mounting groove, and the end face of the base shaft forms the fixing position with the bottom of the body. The operating lever passes through the mounting through hole.

[0012] The anti-loosening component is provided on the side of the body where the mounting through hole is opened.

[0013] This embodiment defines the direction of force application of the anti-loosening component, and can indirectly apply the axial force of the base shaft through the operating lever, thereby providing radial constraint to the side wall of the mounting groove. Combined with the fixed position formed by the bottom of the groove and the end face of the base shaft, it achieves bidirectional axial limiting (providing double friction), reducing or avoiding loosening under high torque.

[0014] In one embodiment, a plurality of anti-loosening spacers are disposed in the mounting through hole, and the axial direction of the anti-loosening elements is parallel to the axial direction of the control lever.

[0015] In this embodiment, multiple anti-loosening spacer rings are placed in the mounting through hole. This uniform layout allows the preload to be evenly transmitted to the end of the control lever, thereby eliminating single-point stress concentration. Furthermore, the parallel force application direction can maximize the frictional resistance torque, achieving zero angular displacement under high torque.

[0016] In one embodiment, the anti-loosening element is threadedly connected to the body.

[0017] This embodiment provides adjustable preload through the threaded connection between the anti-loosening component and the main body, which enhances anti-loosening stability and improves disassembly and assembly efficiency.

[0018] In one embodiment, the inner wall surface of the body has an internal thread, and the outer wall surface of the base shaft has an external thread that engages with the internal thread;

[0019] The control lever includes a shaft and an extension block. The extension block is fixed to the end of the shaft and is located in the mounting groove. It abuts against the outer end face of the base shaft and the anti-loosening component, respectively. The extension block is located in a fixed position.

[0020] In this embodiment, the threaded connection between the body and the base shaft improves assembly and disassembly efficiency. Furthermore, the force applied by the anti-loosening component eliminates the thread gap between the body and the base shaft, preventing loosening due to high torque input and facilitating the resistance to greater operating forces. In one embodiment, the anti-loosening component includes a screw, which is threadedly connected to the body.

[0021] The end of the screw abuts against the side of the extension block opposite to the base shaft. The screw is configured to apply force to the base shaft through its connection with the body, thereby forcing the threaded surfaces of the internal thread and the external thread to abut against each other.

[0022] In this embodiment, the axial force of the screw is converted into the normal pressure of the threaded pair, so that the threaded pair moves with zero backlash under alternating load.

[0023] In one embodiment, the end of the screw facing the epitaxial block is provided with an anti-slip pad, and the contact area between the anti-slip pad and the epitaxial block is greater than or equal to the end face area of ​​the screw.

[0024] In this embodiment, the anti-slip pad increases the contact area between the two surfaces and improves the coefficient of friction to prevent fretting wear at the interface.

[0025] In one embodiment, the side of the epitaxial block facing the anti-loosening member has a plurality of protrusions;

[0026] And / or, the side of the epitaxial block facing the anti-loosening member is provided with anti-slip texture;

[0027] And / or, the side of the epitaxial block facing the anti-loosening member has a frosted surface;

[0028] And / or, the side of the epitaxial block facing the anti-loosening member is provided with a plurality of grooves, wherein the inner diameter of the grooves is smaller than the radial dimension of the anti-loosening member.

[0029] In this embodiment, by providing protrusions, anti-slip textures, frosted surfaces, or grooves on the side of the epitaxial block facing the anti-loosening component, the frictional resistance between the epitaxial block and the anti-loosening component can be maximized.

[0030] In one embodiment, the side of the epitaxial block facing the base has a plurality of protrusions;

[0031] And / or, the side of the epitaxial block facing the base is provided with anti-slip texture;

[0032] And / or, the side of the epitaxial block facing the base has a frosted surface;

[0033] And / or, the side of the base shaft facing the control lever is provided with a plurality of protrusions;

[0034] And / or, the side of the base shaft facing the control lever is provided with anti-slip texture;

[0035] And / or, the side of the base shaft facing the control lever has a frosted surface;

[0036] And / or, an anti-slip pad is provided between the base shaft and the extension block.

[0037] This embodiment can generate a mechanical interlocking effect through the design of raised or textured surfaces, and the frosted or sandblasted surface can increase the actual contact area.

[0038] Secondly, embodiments of this application provide a simulator, including the control handle described in the above embodiments.

[0039] The aforementioned control handle and simulator, by designing the connector and base shaft as a detachable connection, not only facilitates the assembly of the joystick but also enables quick disassembly and assembly between the base shaft and the joystick, thus simplifying maintenance and replacement and improving maintenance efficiency. Furthermore, by placing the end of the joystick in a fixed position formed by the base shaft and connector, and using the cooperation between the base shaft and connector to limit the joystick's movement, a single fixation is achieved for the joystick, connector, and base shaft. Simultaneously, by applying force along the axial direction of the joystick using an anti-loosening component, end-face friction is generated through hard contact with the joystick's end face, while simultaneously eliminating assembly gaps between the base shaft and connector, achieving dual fixation of the joystick and base shaft. This enhances torsional strength, ensuring real-time transmission of force feedback between the joystick and base shaft, and reducing or eliminating looseness or lag between the base shaft and joystick.

[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] As mentioned in the background section, the connection between the base shaft and the rocker shaft is mostly achieved using a nut-based threaded connection. This type of connection is prone to loosening when the rocker shaft is subjected to high torque. Specifically, while the threaded connection allows for quick-release, it primarily provides axial locking force and has extremely weak torque transmission capability in the rotational direction (tangential). High torque feedback can cause slight slippage or slippage in the threaded components. Furthermore, threaded fits inevitably have clearance, which increases after repeated forward and reverse forces. Additionally, vibration and impact can cause the nut to loosen, requiring frequent inspection and tightening.

[0052] To address the aforementioned problems, this application provides a control handle and simulator. By designing the connector 200 and the base shaft 100 as a detachable connection, it not only facilitates the assembly of the joystick 300 but also enables quick assembly and disassembly between the base shaft 100 and the joystick 300, thus simplifying maintenance and replacement and improving maintenance efficiency. Furthermore, by positioning the end of the joystick 300 in a fixed position formed by the base shaft 100 and the connector 200, and by utilizing the cooperation between the base shaft 100 and the connector 200, the joystick 300 is limited, simultaneously achieving a single fixation of the joystick 300, the connector 200, and the base shaft 100. Meanwhile, by applying force along the axial direction of the control lever 300 through the anti-loosening component 400, while generating end-face friction force through hard contact with the end face of the control lever 300, the assembly gap between the base shaft 100 and the connecting component 200 can also be eliminated, thereby achieving double fixation of the control lever 300 and the base shaft 100 to improve torsional strength, ensure the real-time transmission of force feedback between the control lever 300 and the base shaft 100, and reduce or eliminate looseness or lag between the base shaft 100 and the control lever 300.

[0053] See Figure 1 , Figure 4 and Figure 5 , Figure 1 This is a schematic diagram of the disassembly structure of a control handle provided according to some embodiments of this application. Figure 4 This is a top view of a control handle provided according to some embodiments of this application. Figure 5 for Figure 4A cross-sectional view of the structure along the center line AA. One embodiment of this application first provides a control handle, which can be applied to flight simulators, driving simulators, or other simulator devices that require the use of a control handle; no specific limitations are imposed here. The control handle may include a base, a joystick 300, a connector 200, and an anti-loosening component 400.

[0054] The base has a base shaft 100; a connector 200 is detachably connected to the base shaft 100, and the base shaft 100 and the connector 200 form a fixed position, the end of the operating lever 300 is located in the fixed position, and the connector 200 is configured to connect to the base shaft 100 to limit the operating lever 300 to the fixed position; an anti-loosening member 400 is provided on the connector 200, one end of the anti-loosening member 400 abuts against the end of the operating lever 300, and the anti-loosening member 400 is configured to apply force to the operating lever 300 along the axial direction of the operating lever 300 so that the operating lever 300 and the base shaft 100 are continuously abutting.

[0055] It is understandable that the base shaft 100 of the base on the control handle is mainly used to connect the joystick 300. That is, the pre-fixed connection between the two is first achieved through the connector 200. The specific connection method can be that the joystick 300 is first inserted into the connector 200, and then the end of the joystick 300 located in the connector 200 is pressed against and tightened by setting the base shaft 100 on the connector 200, thereby realizing the connection of the base shaft 100, the connector 200 and the joystick 300.

[0056] More specifically, the connector 200 can be connected as a cylindrical nut structure, and the inner or outer wall is provided with threads. Correspondingly, the outer or inner wall of the base shaft 100 is provided with threads that match the connector 200, so as to limit the size of the fixed position through the threaded connection between the base shaft 100 and the connector 200, thereby achieving the purpose of limiting the end of the operating lever 300 to the end face of the connector 200 and the base shaft 100.

[0057] To clearly understand the arrangement of the joystick 300 in the connector 200, this embodiment defines a virtual fixing position formed in the connector 200, the size of which can be changed by the movement of the base shaft 100 relative to the connector 200. The joystick 300 passes through the connector 200, and its end located within the connector 200 has an extension block 320. This extension block 320 can engage the joystick 300 within the connector 200. To prevent the joystick 300 from wobbling within the connector 200, the base shaft 100 is connected to the connector 200, for example, by a threaded connection. The base shaft 100 can be continuously moved towards the joystick 300 until the end face of the base shaft 100 abuts against the end face of the extension block 320 (in this state). The other end face of the extension block 320 also abuts against the inner wall surface of the connector 200. In this state, the axial direction of the base shaft 100 coincides with the axial direction of the control lever 300. Thus, the first stage of fixed connection of the control lever 300 is achieved through the cooperation of the base shaft 100 and the connector 200. This connection method can resist the small torque rotation of the control lever 300. If the input torque of the control lever 300 is large, it is easy to cause the base shaft 100, the connector 200 and the control lever 300 to become loose.

[0058] Based on this, in this embodiment, an anti-loosening member 400 is provided between the connector 200 and the end (extended block 320) of the control lever 300. Specifically, the anti-loosening member 400 is inserted through the connector 200, and one end of the anti-loosening member 400 abuts against the control lever 300. This abutment specifically refers to applying force along the axial direction of the control lever 300 to the extended block 320 of the control lever 300 to achieve hard contact with the extended block 320. This arrangement enables the end face of the anti-loosening member 400 to generate static friction with the end face of the extended block 320, which is beneficial for resisting tangential torque. In addition, taking the base shaft 100 as a reference, during the pre-tightening process, the anti-loosening component 400 can move closer to the base shaft 100, thereby pushing the extension block 320 of the operating lever 300 towards the base shaft 100, achieving the purpose of pressing the threads of the base shaft 100 and the connecting component 200 together. In other words, the anti-loosening component 400 can eliminate the gap between the threaded connection of the base shaft 100 and the connecting shaft, so that the threaded meshing surface is subjected to force throughout the entire process. The anti-loosening component 400 achieves the second-stage fixed connection between the base shaft 100 and the operating lever 300.

[0059] The anti-torsion path of the control handle provided in this embodiment can be as follows: the control lever 300 inputs torque to its end, the anti-loosening member 400 makes hard contact with the end of the control lever 300 to increase the friction between the two (generating the first radial friction force), and at the same time eliminates the assembly gap between the base shaft 100 and the connecting member 200 (generating the second radial friction force). The end of the control lever 300 also makes hard contact with the end face of the base shaft 100. The large torque input by the control lever 300 is resisted by the combined action of the first radial friction force and the second radial friction force.

[0060] Of course, an elastic element can also be provided between the anti-loosening element 400 and the connecting element 200 to apply axial force to the anti-loosening element 400 to compensate for the loosening caused by vibration.

[0061] The control handle provided in this application embodiment, by designing the connector 200 and the base shaft 100 as a detachable connection, not only facilitates the assembly of the joystick 300, but also enables quick assembly and disassembly between the base shaft 100 and the joystick 300, thus facilitating maintenance and replacement of the joystick 300 and improving maintenance efficiency. Furthermore, by positioning the end of the joystick 300 in a fixed position formed by the base shaft 100 and the connector 200, and by utilizing the cooperation between the base shaft 100 and the connector 200 to limit the movement of the joystick 300, a single fixation is achieved for the joystick 300, the connector 200, and the base shaft 100. Meanwhile, by applying force along the axial direction of the control lever 300 through the anti-loosening component 400, while generating end-face friction force through hard contact with the end face of the control lever 300, the assembly gap between the base shaft 100 and the connecting component 200 can also be eliminated, thereby achieving double fixation of the control lever 300 and the base shaft 100 to improve torsional strength, ensure the real-time transmission of force feedback between the control lever 300 and the base shaft 100, and reduce or eliminate looseness or lag between the base shaft 100 and the control lever 300.

[0062] Below, we will combine the appendix Figure 1 -Appendix Figure 5 The specific structure of the control handle provided in the embodiments of this application will be described in detail.

[0063] like Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the disassembly structure of the control handle from another perspective, according to some embodiments of this application. Figure 3 This is a schematic diagram of the disassembled structure of the base shaft and the connector from another perspective according to some embodiments of this application. In some embodiments, the connector 200 includes a body 210, which has a mounting groove 211 and a mounting through hole 212 on the side of the mounting groove 211 away from the base shaft. The extension block 320 of the base shaft 100 is installed in the mounting groove 211. The end face of the base shaft 100 and the side of the body 210 away from the base shaft form a fixed position, and the extension block 320 is located in the fixed position. The operating lever 300 passes through the mounting through hole 212. The anti-loosening member 400 is provided on the side of the body 210 where the mounting through hole 212 is provided.

[0064] It is understandable that the body 210 of the connector 200 is a cylindrical nut structure, and the mounting groove 211 formed inside it is also cylindrical. The cylindrical mounting groove 211 has arc-shaped sidewalls and a circular bottom surface, and the bottom surface of the mounting groove 211 is provided with a mounting through hole 212, which is mainly used to pass through the control lever 300. The specific installation process is as follows: the joystick 300 is defined as including an extension block 320 located in the mounting groove 211 and a gripping part opposite to the extension block 320. During installation, the base shaft 100 is separated from the body 210, the gripping part of the joystick 300 is located at the opening of the mounting groove 211 and moves into the mounting groove 211 until it passes through the mounting through hole 212 at the bottom of the mounting groove 211, and continues to move until the extension block 320 of the joystick 300 reaches the bottom of the mounting groove 211; then, the base shaft 100 is connected to the body 210, and the end of the base shaft 100 also enters from the opening of the mounting groove 211 until it abuts against the extension block 320 of the joystick 300, thereby fixing the joystick 300.

[0065] Of course, in addition to the above installation method, the control lever 300 and the connector 200 can also be interlocked, with the outer extension block 320 at the bottom of the control lever 300 limited by the mounting hole 212, and the other side limited by the housing of the control lever 300 or other parts, thus making the connector 200 and the control lever 300 a non-detachable structure. This arrangement can further improve the installation efficiency of the control lever 300 and the base shaft 100.

[0066] It should be noted that since the radial dimension of the extension block 320 is larger than the diameter of the lever body 300, it can be snapped into the mounting groove 211 and will not come out of the body 210. In addition, to ensure that the axis of the lever 300 coincides with the axis of the base shaft 100, the diameter of the mounting through hole 212 can be matched with the diameter of the lever 300, so that the lever 300 just passes through the mounting through hole 212.

[0067] Based on the shape design of the main body 210 and the force direction of the anti-loosening member 400, the anti-loosening member 400 is provided on the side of the main body 210 where the mounting through hole 212 is opened. It should be noted that in this embodiment, the anti-loosening member 400 passes through the main body 210, with one end exposed and the other end exposed at the above-mentioned fixing position, for hard contact (not fixed connection) with the extension block 320 of the control lever 300, so as to provide static friction between the two.

[0068] In this embodiment, the anti-loosening component 400 can indirectly apply axial force to the base shaft 100 through the operating lever 300, thereby providing radial constraint to the side wall of the mounting groove 211. Combined with the fixed position formed by the bottom of the groove and the end face of the base shaft 100, it achieves bidirectional axial limiting (providing double friction), reducing or avoiding loosening under high torque.

[0069] like Figure 4 As shown, in some embodiments, a plurality of anti-loosening elements 400 are spaced in a ring around the mounting through hole 212, and the axial direction of the anti-loosening elements 400 is parallel to the axial direction of the control lever 300.

[0070] Specifically, multiple mounting holes are spaced apart on the body 210 around the axis of the mounting through hole 212, and corresponding anti-loosening components 400 are installed in the mounting holes one by one, ensuring that the axial direction of the anti-loosening component 400 is parallel to the axial direction of the operating lever 300. This uniform layout allows the preload to be evenly transmitted to the end of the operating lever 300, eliminating single-point stress concentration, and the parallel force direction maximizes the frictional resistance torque, achieving zero angular displacement under high torque. For example, three anti-loosening components 400 are spaced apart and pass through the mounting through hole 212 on the body 210.

[0071] It should be noted that the anti-loosening member 400 in this embodiment can be movably inserted into the mounting hole, but an external force needs to be continuously applied to the anti-loosening member 400 by means of an external elastic member so that the end of the anti-loosening member 400 can continuously make hard contact with the end of the operating lever 300.

[0072] In addition to the above-mentioned method of setting the anti-loosening component 400, it can also be, as follows: Figure 5 As shown, in some embodiments, the anti-loosening component 400 is threadedly connected to the body 210. Specifically, the mounting hole on the body 210 is a threaded hole. In one example, the anti-loosening component 400 includes a screw, which is threadedly connected to the body 210. For example, the screw can be a countersunk screw, which is screwed into the body 210 through the threaded hole. In this embodiment, the threaded connection between the anti-loosening component 400 and the body 210 can provide adjustable preload, which can enhance anti-loosening stability and improve disassembly and assembly efficiency.

[0073] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the inner wall surface of the body 210 has an internal thread, and the outer wall surface of the base shaft 100 has an external thread that engages with the internal thread; the operating lever 300 includes a shaft 310 and an extension block 320, the extension block 320 is fixed to the end of the shaft 310, the extension block 320 is disposed in the mounting groove 211, and abuts against the outer end face of the base shaft 100 and the anti-loosening member 400 respectively.

[0074] Specifically, the threaded connection between the body 210 and the base shaft 100 improves assembly and disassembly efficiency. The extended block 320 located at the end of the shaft 310 is disc-shaped (similar to the shape of a flange 320) and can be welded to the shaft 310. Its surface can be roughened to ensure tight contact with the end face of the base shaft 100 and the anti-loosening component 400. In this embodiment, the extended block 320 is clamped between the end face of the base shaft 100 and the anti-loosening component 400, forming a rigid clamp (transmitting axial clamping force to the base shaft 100 to eliminate thread clearance; providing a friction interface to the anti-loosening component 400 to resist torque rotation). Furthermore, the thread clearance between the body 210 and the base shaft 100 is eliminated by the force applied by the anti-loosening component 400, preventing loosening due to high torque input and facilitating the resistance to greater operating forces.

[0075] like Figure 5 As shown, in some embodiments, the end of the screw abuts against the side of the extension block 320 facing away from the base shaft 100, and the screw is configured to apply force to the base shaft 100 through its connection with the body 210 to force the threaded surfaces of the internal and external threads to abut against each other.

[0076] Specifically, the screw can be a countersunk screw, the end face of which can be ground flat to ensure sufficient contact area with the extension block 320 and to make hard contact with the end face of the extension block 320. Tightening the screw generates an axial force, causing the body 210 to move relative to the base shaft 100, thereby forcing the meshing surfaces of the internal and external threads to press together. In this embodiment, by converting the axial force of the screw into normal pressure of the threaded pair, the threaded pair moves with zero backlash under alternating loads.

[0077] In some embodiments, an anti-slip pad is provided at one end of the screw facing the extension block 320, and the contact area between the anti-slip pad and the extension block 320 is greater than or equal to the end face area of ​​the screw.

[0078] Specifically, anti-slip pads, such as polyurethane anti-slip pads, can be embedded at the ends of the screws, but there are no limitations. The anti-slip pads increase the contact area between the two components, improving the coefficient of friction and preventing fretting wear at the interface. Alternatively, micro-textures can be machined on the contact surface between the anti-slip pad and the outer extension block 320 to further enhance their static friction.

[0079] To maximize the frictional resistance between the epitaxial block 320 and the anti-loosening member 400, in some embodiments, the side of the epitaxial block 320 facing the anti-loosening member 400 is provided with multiple protrusions. Specifically, the side of the epitaxial block 320 facing the anti-loosening member 400 is provided with several tiny protrusions, which can also be understood as bumps, and the surface can be sandblasted to increase the contact pressure. Alternatively, in one example, the side of the epitaxial block 320 facing the anti-loosening member 400 is constructed with anti-slip textures; for example, a cross-grid texture is used to maximize frictional resistance. Alternatively, in one example, the side of the epitaxial block 320 facing the anti-loosening member 400 is a frosted surface; the surface of the epitaxial block 320 can be sandblasted with alumina to increase mechanical engagement through the micro-uneven structure of the surface. Alternatively, in one example, the side of the epitaxial block 320 facing the anti-loosening member 400 is constructed with multiple grooves, wherein the inner diameter of the grooves is smaller than the radial dimension of the anti-loosening member 400. Specifically, multiple tiny grooves can be constructed on the surface of the epitaxial block 320. This design of tiny grooves is equivalent to the aforementioned multiple protrusions, which can increase the contact point pressure. Of course, this groove design can be used in conjunction with the anti-slip pad provided at the end of the screw, so that part of the anti-slip pad is recessed into the groove, which can achieve the purpose of increasing mechanical engagement.

[0080] In addition to the design that maximizes the frictional resistance between the epitaxial block 320 and the anti-loosening component 400, the frictional resistance between the epitaxial block 320 and the base shaft 100 can also be maximized. This can be achieved by, in some embodiments, providing multiple protrusions on the side of the epitaxial block 320 facing the base; or, constructing anti-slip textures on the side of the epitaxial block 320 facing the base; or, having a frosted surface on the side of the base shaft 100 facing the control lever 300; or, constructing anti-slip textures on the side of the base shaft 100 facing the control lever 300; or, having a frosted surface on the side of the base shaft 100 facing the control lever 300. Specifically, the protrusions or textures described above can create a mechanical interlocking effect, and the frosted or sandblasted surface can increase the actual contact area. It should be noted that the anti-slip design on the epitaxial block 320 and the base shaft 100 can be understood with reference to the above embodiments and will not be repeated here.

[0081] In one example, an anti-slip pad is provided between the base shaft 100 and the extension block 320. Specifically, the anti-slip pad is designed to increase the anti-slip performance between the base shaft 100 and the extension block 320. This embodiment can further improve the total torsional torque by using a multi-part anti-slip design to counteract the input of large torque.

[0082] Based on the same inventive concept, this application also provides a simulator, which may include the control handle described in the above embodiments.

[0083] It is understood that the simulators in this embodiment include, but are not limited to, flight simulators, driving simulators, and construction machinery simulators. The base of the aforementioned control handle has a built-in encoder and force feedback motor driver, which can communicate with the simulator's main control system via a CAN bus to ensure real-time synchronization between operating commands and force feedback.

[0084] Taking a flight simulator as an example, the joystick 300 is designed for dual-axis (pitch / roll) control. When the user pushes or pulls the joystick 300, the torque is transmitted to the connector 200 through the extension block 320. The anti-loosening component 400 presses down to eliminate thread clearance, and the base shaft 100 transmits the angle signal to the main control system. Due to the design of the anti-loosening component 400, it can be ensured that it will not loosen under high torque input, providing operating accuracy and user experience.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
