Description

Technical Field

[0001] This application relates to the field of mechanical equipment operating joysticks, and more particularly to a universal handle. Background Technology

[0002] In industrial production, equipment operation, and daily life, handles are common manipulation and force-applying components, and their performance directly affects the operator's comfort, work efficiency, and operational safety. Traditional universal handles typically achieve multi-angle rotation through ball joints.

[0003] However, the ball joint and the spherical groove of the connector are in point-to-surface contact, and the contact area is relatively small. The contact point is prone to stress concentration. Long-term use may lead to increased wear on the outer wall of the ball joint, and even deformation and cracks. Wear on the ball joint and the outer wall of the connector will also affect the return of the handle, thereby affecting the service life of the handle and the safety of operation. Utility Model Content

[0004] This application provides a universal handle to solve the problem that the contact points of the universal handle are easily deformed due to the use of ball joints.

[0005] This application provides a universal handle, including a housing, an outer pivot, a rotating body, an inner pivot, a rod, a magnet, a Hall effect chip, and a PCB board; a receiving groove is formed inside the housing, and the receiving groove passes through one side wall of the housing; two outer pivots are provided, the two outer pivots are coaxially arranged and both are arranged in the receiving groove, the outer pivots are fixedly arranged on the housing along the opening direction perpendicular to the receiving groove, and a gap is provided between the ends of the two outer pivots away from the inner wall of the receiving groove.

[0006] The rotating body is mounted on two outer rotating shafts, which are rotatably connected to the rotating body or the housing. The outer rotating shafts extend into the rotating body. There is a gap between the rotating body and the inner wall of the receiving groove. The rotating body has a rotation space so that the rotating body can rotate around the axis of the outer rotating shaft. The inner rotating shaft is mounted on the rotating body. The axis of the inner rotating shaft is perpendicular to the axis of the outer rotating shaft. The axis of the inner rotating shaft is perpendicular to the opening direction of the receiving groove. The inner rotating shaft passes through the rotation space.

[0007] The rod extends through the rotating body along the opening direction of the receiving groove, and one end of the rod extends outside the housing. The inner rotating shaft is rotatably connected to the rod or the rotating body. A gap is provided between the inner wall of the rod and the rotating body along the axis perpendicular to the inner rotating shaft so that the rod can rotate around the inner rotating shaft within the rotating body. The magnet disk is fixedly installed at one end of the rod located in the receiving groove. The Hall chip is installed in the receiving groove, and along the axis of the rod, the Hall chip is located on the outside of the rod, with the Hall chip and the magnet disk spaced apart. The PCB board is installed in the receiving groove, and the Hall chip is mounted on the PCB board.

[0008] In this application, the cooperation between the outer pivot and the rotating body allows the rotating body to rotate around the outer pivot axis, while the connection between the inner pivot, the rod, and the rotating body allows the rod to rotate around the inner pivot within the rotating body. This dual-axis, mutually perpendicular design gives the handle the ability to flexibly adjust its angle in two different planes, greatly expanding the possibilities of the handle's operating direction and meeting the needs of complex angle control in industrial equipment and the need for flexible multi-angle control when simulating different actions in game controllers.

[0009] The housing's recessed design provides integrated installation space for all components, resulting in a compact overall structure. The outer shaft is fixed to the housing, while the rotating body, inner shaft, and rod are assembled in an orderly manner within the recessed space. This ensures the stability of each component during rotation, reduces wobbling and displacement, and guarantees the precision of handle operation.

[0010] The combination of a magnetic disk and a Hall effect chip utilizes the principle of magnetic field induction to detect the rotation angle of the rod in real time. Compared to traditional contact angle sensors, this non-contact method avoids mechanical wear, improves detection accuracy and lifespan, and can quickly feed back angle information to the connected equipment control system.

[0011] Meanwhile, the structure achieves rotation through inner and outer rotating shafts, avoiding localized friction and uneven stress caused by surface contact, thus reducing costs while improving service life and accuracy.

[0012] In some embodiments of this application, the magnet disk is at least partially disposed within the rod body.

[0013] By incorporating at least part of the magnet disc within the rod body, the internal space of the rod body can be effectively utilized, avoiding the problem of occupying extra space due to the external placement of the magnet disc. This further enhances the compactness of the overall handle structure, making it particularly suitable for devices with strict space requirements, such as small control handles in portable electronic devices.

[0014] The rod encloses part of the magnet disk, which can prevent the magnet disk from being physically damaged by external collisions, scratches, etc., while reducing the corrosion of the magnet disk by dust, moisture, etc., ensuring the magnetic field stability of the magnet disk, and thus maintaining the accuracy of the Hall chip's detection angle.

[0015] In some embodiments of this application, the inner wall of the housing extends inward to form an annular boss, the rod passes through the annular boss and a gap is provided between the rod and the annular boss, the universal handle also includes a rotating ring, the rotating ring is disposed in the annular boss and the rotating ring is fixed relative to the housing, the outer rotating shaft is disposed on the rotating ring, and the rotating body is disposed inside the rotating ring.

[0016] The annular boss on the inner wall of the housing not only provides a supporting reference for the rod but also enhances the overall structural strength of the housing. The rotating ring is set inside the annular boss and fixed relative to the housing, providing a stable mounting base for the outer rotating shaft. This makes the outer rotating shaft more stable during rotation and reduces rotational jamming or decreased accuracy caused by factors such as housing deformation.

[0017] The layered structural design arranges different functional components in their respective positions in an orderly manner, which facilitates the installation and debugging of components by workers during the assembly process; it also makes it easy to disassemble and replace each component during later maintenance, reducing the difficulty and cost of maintenance.

[0018] In some embodiments of this application, a reference plane is formed on the side of the annular boss away from the magnet disk along the opening direction perpendicular to the receiving groove; the universal handle also includes a reset ring and a reset spring, the reset ring is slidably connected to the rod body along the axial direction of the rod body, the reset ring abuts against the reference plane, the reset spring is disposed on the rod body, one end of the reset spring abuts against the side of the reset ring away from the reference plane, and the other end of the reset spring is fixed relative to the end of the rod body located outside the housing.

[0019] The reset ring and reset spring are designed so that when the lever is rotated under force and the external force is removed, the spring force pushes the reset ring, thereby driving the lever back to its initial position, achieving an automatic reset function. In game controllers, this allows the controller to automatically return to center after each operation, facilitating the next action. In industrial equipment control, it ensures consistent controller operation and prevents operational errors caused by forgetting to return it to its original position.

[0020] The reset ring abuts against the reference plane, and the abutment part forms an arc-shaped surface, which can effectively disperse the pressure during the reset process, reduce local wear between the reset ring and the annular boss, and at the same time play a certain buffering role, reducing the impact of the impact force generated during reset on the internal components and extending the service life of the handle.

[0021] In some embodiments of this application, the portion of the reset ring that abuts against the reference plane has an arc-shaped surface. The arc-shaped surface design reduces the contact area and distributes the friction force more evenly when the reset ring moves relative to the reference plane. Compared to flat contact, this significantly reduces the coefficient of friction, reduces jamming during the reset process, and also reduces noise generated by friction, improving the smoothness and quietness of the handle operation.

[0022] The unique shape of the arc surface guides the reset ring to move more smoothly during the reset process, avoiding tilting or displacement of the reset ring due to uneven force, ensuring that the rod returns to the initial position accurately and stably, and improving the reliability of the handle's automatic reset function.

[0023] In some embodiments of this application, the universal handle further includes a pad, which is disposed between the reference plane of the reset ring and the annular boss, and the pad is fixedly connected to the annular boss. The pad, disposed between the reference plane of the reset ring and the annular boss, serves to isolate and buffer, preventing the reset ring from causing wear on the surface of the annular boss during long-term reciprocating motion, extending the service life of the annular boss, and thus ensuring the stability of the entire handle structure.

[0024] By selecting pads of different materials and thicknesses, the gap and friction between the reset ring and the annular boss can be finely adjusted, thereby adjusting the reset force of the handle to a certain extent to suit the preferences of different users for the force of handle operation or the needs of the reset force in different application scenarios.

[0025] In some embodiments of this application, the universal handle further includes a threaded connector that passes through and securely connects the rotating ring, the annular boss, and the pad. The threaded connector, by passing through and securing the rotating ring, the annular boss, and the pad, tightly integrates these three key components into a single unit, greatly enhancing the robustness of the connection between the components. This prevents loosening or displacement of the components under complex working conditions such as frequent handle rotation and stress, ensuring the reliability of the handle structure.

[0026] When internal components need to be repaired or replaced, threaded connections allow for easy separation of the relevant components simply by unscrewing the threaded connector, facilitating subsequent inspection and maintenance and improving repair efficiency.

[0027] In some embodiments of this application, the universal handle also includes a handle, which is fixedly disposed at the end of the rod outside the housing. The handle's fixed placement at the end of the rod outside the housing increases the contact area between the operator and the handle, providing a more comfortable and stable grip position, and facilitating the operator's application of force. Handle designs of different shapes and materials can also meet the different users' needs for feel; for example, rubber handles can increase friction, prevent slippage, and improve operational safety.

[0028] In some embodiments of this application, the universal handle further includes a flexible protective sleeve and a threaded component. One end of the flexible protective sleeve is fixedly connected to the handle, and the other end of the flexible protective sleeve is sleeved on the housing. The flexible protective sleeve and the housing are fixedly connected by the threaded component, and the rod is located inside the flexible protective sleeve.

[0029] The flexible protective sleeve wraps around the rod and is fixedly connected to the handle and housing. It can effectively prevent dust, moisture, debris and other objects from entering the handle, avoid internal components from rusting, short circuits and other malfunctions caused by external environmental factors, and extend the service life of the handle.

[0030] In some embodiments of this application, the housing includes a base, a lower cover, and an upper cover. The base is located between the upper cover and the lower cover. A receiving groove passes through the base and the upper cover. The lower cover is placed on the base. An annular snap-fit ​​groove is formed between the base and the upper cover. The end of the flexible protective sleeve is disposed in the annular snap-fit ​​groove. The lower cover and the base are fixedly connected by threaded parts. The PCB board and the Hall chip are both disposed between the lower cover and the base.

[0031] The housing adopts a combination structure of base, lower cover and upper cover, and the components are fixedly connected by threaded parts. During the assembly process, it is convenient to install and debug each component; during maintenance, it is easy to disassemble each component to inspect and replace the internal PCB board, Hall chip, etc., reducing production and maintenance costs.

[0052] In industrial production, equipment operation, and daily life, handles are common manipulation and force-applying components, and their performance directly affects the operator's comfort, work efficiency, and operational safety. Traditional universal handles typically achieve multi-angle rotation through ball joints.

[0053] However, the ball joint and the spherical groove of the connector are in point-to-surface contact, and the contact area is relatively small. The contact point is prone to stress concentration. Long-term use may lead to increased wear on the outer wall of the ball joint, and even deformation and cracks. Wear on the ball joint and the outer wall of the connector will also affect the return of the handle, thereby affecting the service life of the handle and the safety of operation.

[0054] Therefore, please refer to Figure 1 This application provides a universal handle, including a housing 01, an outer pivot 02, a rotating body 03, an inner pivot 04, a rod 05, a magnetic disk 06, a Hall chip 07, and a PCB board 08.

[0055] Please refer to Figure 1 The housing 01 has a receiving groove 011 formed inside it, and the receiving groove 011 penetrates one side wall of the housing 01. The housing 01 can be made of plastic, such as high-strength ABS plastic, or metal. The receiving groove 011 can penetrate one side wall of the housing 01. The opening direction of the receiving groove 011 is the depth direction. Along the opening direction of the receiving groove 011, the inner wall of the receiving groove 011 may not be the same everywhere.

[0056] Please refer to Figure 1 and Figure 2There are two outer rotating shafts 02. The two outer rotating shafts 02 are coaxially arranged and both are set in the receiving groove 011. The outer rotating shafts 02 are fixedly arranged on the housing 01 along the opening direction perpendicular to the receiving groove 011. A gap is provided between the ends of the two outer rotating shafts 02 away from the inner wall of the receiving groove 011.

[0057] Please refer to Figure 1 and Figure 2 The rotating body 03 is mounted on two outer rotating shafts 02. The outer rotating shafts 02 are rotatably connected to the rotating body 03 or the housing 01. The outer rotating shafts 02 extend into the rotating body 03. There is a gap between the rotating body 03 and the inner wall of the receiving groove 011. There is a rotation space inside the rotating body 03 so that the rotating body 03 can rotate around the axis of the outer rotating shafts 02.

[0058] Please refer to Figure 2 The inner rotating shaft 04 is set on the rotating body 03. The axis of the inner rotating shaft 04 is perpendicular to the axis of the outer rotating shaft 02. The axis of the inner rotating shaft 04 is perpendicular to the opening direction of the receiving groove 011. The inner rotating shaft 04 passes through the rotating space.

[0059] Please refer to Figure 2 and Figure 3 The rod 05 passes through the rotating body 03 along the opening direction of the receiving groove 011, and one end of the rod 05 extends to the outside of the housing 01. The inner rotating shaft 04 is rotatably connected to the rod 05 or the rotating body 03. A gap is provided between the rod 05 and the inner wall of the rotating body 03 along the axial direction perpendicular to the inner rotating shaft 04, so that the rod 05 can rotate around the inner rotating shaft 04 in the rotating body 03.

[0060] Please refer to Figure 3 and Figure 4 The magnet disk 06 is fixedly installed at one end of the rod 05 located in the receiving groove.

[0061] Please refer to Figure 3 and Figure 4 The Hall chip 07 is disposed in the receiving groove 011. Along the axial direction of the rod 05, the Hall chip 07 is located outside the rod 05, and the Hall chip 07 and the magnet disk 06 are distributed at intervals.

[0062] Please refer to Figure 3 and Figure 4 The PCB board 08 is located within the receiving slot 011, and the Hall chip 07 is mounted on the PCB board 08. Terminal blocks 081 can be configured on the PCB board 08 for signal output and power supply.

[0063] Please refer to the following: Figures 1-4In this application, the cooperation between the outer pivot 02 and the rotating body 03 allows the rotating body 03 to rotate around the axis of the outer pivot 02, while the connection between the inner pivot 04 and the rod 05 and the rotating body 03 allows the rod 05 to rotate around the inner pivot 04 within the rotating body 03. This dual-axis and mutually perpendicular design gives the handle the ability to flexibly adjust its angle in two different planes, greatly expanding the possibilities of the handle's operating direction and meeting the needs of complex angle control in industrial equipment and the need for flexible multi-angle control when simulating different actions in game controllers.

[0064] The housing 01's receiving groove 011 provides integrated installation space for all components, making the overall structure compact. The outer rotating shaft 02 is fixed to the housing 01, and the rotating body 03, inner rotating shaft 04, and rod 05 are assembled in an orderly manner within the receiving groove 011, ensuring the stability of each component during rotation, reducing wobbling and displacement, and ensuring the accuracy of handle operation.

[0065] The combination of the magnetic disk 06 and the Hall chip 07 utilizes the principle of magnetic field induction to detect the rotation angle of the rod 05 in real time. Compared to traditional contact angle sensors, this non-contact method avoids mechanical wear, improves detection accuracy and service life, and can quickly feed back angle information to the connected equipment control system.

[0066] Meanwhile, the structure achieves rotation through the inner rotating shaft 04 and the outer rotating shaft 02, avoiding local friction and uneven stress caused by surface contact, reducing costs while improving service life and accuracy.

[0067] Please refer to Figure 4 In some examples, the magnet disk 06 is at least partially disposed within the rod body 05.

[0068] Please refer to Figure 4 By placing the magnet disk 06 at least partially inside the rod body 05, the internal space of the rod body 05 can be effectively utilized, avoiding the problem of occupying extra space caused by placing the magnet disk 06 externally. This further improves the compactness of the overall handle structure, making it particularly suitable for devices with strict space requirements, such as small control handles in portable electronic devices.

[0069] The rod 05 encloses part of the magnet disk 06, which can prevent the magnet disk 06 from being physically damaged by external collisions, scratches, etc., while reducing the corrosion of the magnet disk 06 by dust, moisture, etc., ensuring the magnetic field stability of the magnet disk 06, and thus maintaining the accuracy of the detection angle of the Hall chip 07.

[0070] Please refer to Figure 4 For example, the magnet disk 06 can be completely embedded in the rod 05, or it can be partially protruding.

[0071] Please refer to Figure 5In some examples, the inner wall of the housing 01 extends inward to form an annular boss 012, the rod 05 passes through the annular boss 012 and a gap is provided between the rod 05 and the annular boss 012, the universal handle also includes a rotating ring 09, the rotating ring 09 is disposed in the annular boss 012 and the rotating ring 09 is fixed relative to the housing 01, the outer rotating shaft 02 is disposed on the rotating ring 09, and the rotating body 03 is disposed inside the rotating ring 09.

[0072] Please refer to Figure 5 The annular boss 012 on the inner wall of the housing 01 not only provides a supporting reference for the rod 05, but also enhances the overall structural strength of the housing 01. The rotating ring 09 is set inside the annular boss 012 and is fixed relative to the housing 01, providing a stable mounting base for the outer rotating shaft 02, making the outer rotating shaft 02 more stable during rotation and reducing rotation jamming or decrease in accuracy caused by factors such as deformation of the housing 01.

[0073] The layered structural design arranges different functional components in their respective positions in an orderly manner, which facilitates the installation and debugging of components by workers during the assembly process; it also makes it easy to disassemble and replace each component during later maintenance, reducing the difficulty and cost of maintenance.

[0074] In some examples, the upper diameter of the annular boss 012 may be larger than the lower diameter along the opening direction of the receiving groove 011, thereby facilitating the inclusion of the aforementioned rotating body 03 and other parts inside the annular boss 012.

[0075] The rotating ring 09 can be pre-installed with the outer rotating shaft 02, rotating body 03, inner rotating shaft 04 and rod body 05 for easy production and assembly.

[0076] Please refer to Figure 5 In some examples, along the opening direction perpendicular to the receiving groove 011, the annular boss 012 forms a reference plane 013 on the side away from the magnet disk 06; please refer to Figure 6 The universal handle also includes a reset ring 10 and a reset spring 11. The reset ring 10 is slidably connected to the rod 05 along the axial direction of the rod 05 and abuts against the reference plane 013. The reset spring 11 is disposed on the rod 05. One end of the reset spring 11 abuts against the side of the reset ring 10 away from the reference plane 013, and the other end of the reset spring 11 is fixed relative to the end of the rod 05 located outside the housing 01.

[0077] Please refer to Figure 5 and Figure 6The reset ring 10 and reset spring 11 are designed so that when the lever 05 is rotated under force and the external force is removed, the elastic force of the reset spring 11 pushes the reset ring 10, thereby driving the lever 05 back to its initial position, achieving an automatic reset function. In applications such as game controllers, this allows the controller to automatically return to center after each operation, facilitating the next action. In industrial equipment control, it ensures the consistency of the controller's operating state and avoids operational errors caused by forgetting to return it to its original position.

[0078] Please refer to Figure 5 and Figure 6 The reset ring 10 abuts against the reference plane 013, and the abutting part forms an arc-shaped surface 101, which can effectively disperse the pressure during the reset process, reduce the local wear between the reset ring 10 and the annular boss 012, and at the same time play a certain buffering role, reduce the impact of the impact force generated during reset on the internal components, and extend the service life of the handle.

[0079] Please refer to Figure 5 and Figure 6 In some examples, the reference plane 013 can be a plane of the boss near the opening of the housing, and the reference plane 013 can be a toroidal surface, or it can be a toroidal surface with a rectangular outer edge and a circular inner edge.

[0080] Please refer to Figure 5 and Figure 6 In some examples, the portion of the reset ring 10 that abuts against the reference plane 013 forms an arc-shaped surface 101. The design of the arc-shaped surface 101 reduces the contact area and distributes the friction force more evenly when the reset ring 10 moves relative to the reference plane 013. Compared with flat contact, it can significantly reduce the coefficient of friction, reduce the jamming phenomenon during the reset process, and reduce the noise generated by friction, thereby improving the smoothness and quietness of the handle operation.

[0081] The unique shape of the arc surface 101 can guide the reset ring 10 to move more smoothly during the reset process, avoiding tilting or displacement of the reset ring 10 due to uneven force, ensuring that the rod 05 returns to the initial position accurately and stably, and improving the reliability of the handle's automatic reset function.

[0082] Please refer to Figure 5 and Figure 6 In some examples, the curvature of the arc surface 101 of the reset ring 10 can be equal everywhere along the axial direction of the rod 05. The central angle of the arc of the cross section of the arc surface 101 of the reset ring 10 can be designed according to the rotation angle of the universal handle, such as 15°, 30° or 45°.

[0083] Please refer to Figure 6 and Figure 7In some examples, the universal handle also includes a pad 12, which is disposed between the reset ring 10 and the reference plane 013 of the annular boss 012, and is fixedly connected to the annular boss 012. The pad 12, disposed between the reset ring 10 and the reference plane 013 of the annular boss 012, serves to isolate and buffer, preventing the reset ring 10 from causing wear on the surface of the annular boss 012 during long-term reciprocating motion, extending the service life of the annular boss 012, and thus ensuring the stability of the entire handle structure.

[0084] Please refer to Figure 6 and Figure 7 By selecting pads 12 of different materials and thicknesses, the gap and friction between the reset ring 10 and the annular boss 012 can be finely adjusted, thereby adjusting the reset force of the handle to a certain extent to adapt to the preferences of different users for the force of handle operation or the needs of the reset force in different application scenarios.

[0085] Please refer to Figure 7 In some examples, the universal handle also includes a threaded connector 13, which passes through and securely connects the rotating ring 09, the annular boss 012, and the pad 12. The threaded connector 13, by passing through and securing the rotating ring 09, the annular boss 012, and the pad 12, tightly integrates these three key components into a single unit, greatly enhancing the robustness of the connection between the components. This prevents loosening or displacement of the components under complex working conditions such as frequent rotation and stress on the handle, ensuring the reliability of the handle structure.

[0086] When internal components need to be repaired or replaced, the threaded connection allows for easy separation of the relevant components simply by unscrewing the threaded connector 13, facilitating subsequent inspection and maintenance and improving repair efficiency.

[0087] Please refer to Figure 7 In some examples, the universal handle also includes a handle 14, which is fixedly mounted on the end of the rod 05 outside the housing 01. The handle 14, fixedly mounted on the end of the rod 05 outside the housing 01, increases the contact area between the operator and the handle, providing a more comfortable and stable grip position, and facilitating the operator's application of force. The design of handles 14 with different shapes and materials can also meet the different users' needs for feel; for example, a rubber handle 14 can increase friction, prevent slippage, and improve operational safety.

[0088] Please refer to Figure 7 and Figure 8In some examples, the universal handle also includes a flexible protective sleeve 15 and a threaded component 16. One end of the flexible protective sleeve 15 is fixedly connected to the handle 14, and the other end of the flexible protective sleeve 15 is fitted onto the housing 01. The flexible protective sleeve 15 and the housing 01 are fixedly connected by the threaded component 16, and the rod body 05 is located inside the flexible protective sleeve 15.

[0089] The flexible protective sleeve 15 wraps around the rod body 05 and is fixedly connected to the handle 14 and the housing 01. It can effectively prevent dust, moisture, debris and other objects from entering the handle, avoid internal parts from rusting, short circuits and other failures due to external environmental factors, and extend the service life of the handle.

[0090] Please refer to Figure 9 In some examples, housing 01 includes base 014, lower cover 015 and upper cover 016. Base 014 is located between upper cover 016 and lower cover 015. Receiving groove 011 passes through base 014 and upper cover 016. Lower cover 015 is placed on base 014. An annular snap-fit ​​groove 017 is formed between base 014 and upper cover 016. The end of flexible protective sleeve 15 is disposed in an annular snap-fit ​​groove 017. Lower cover 015 and base 014 are fixedly connected by threaded parts 16. PCB board 08 and Hall chip 07 are both disposed between lower cover 015 and base 014.

[0091] Please refer to Figure 9 The housing 01 adopts a combination structure of base 014, lower cover 015 and upper cover 016. The components are fixedly connected by threaded parts 16. During assembly, it is convenient to install and debug the components. During maintenance, it is easy to disassemble the components to inspect and replace the internal PCB board 08, Hall chip 07, etc., reducing production and maintenance costs.

[0092] In some embodiments, please refer to Figure 7 and Figure 10 This application provides a universal handle, including a housing 01, an outer pivot 02, a rotating body 03, an inner pivot 04, a rod 05, a magnet disk 06, a Hall chip 07, a PCB board 08, a rotating ring 09, a reset ring 10, a reset spring 11, a pad 12, a threaded connector 13, a handle 14, a flexible protective sleeve 15, and a threaded component 16.

[0093] Please refer to Figure 10 In some examples, the housing 01, serving as the basic support component for the universal handle, can be injection molded from high-strength ABS plastic, possessing excellent impact resistance and corrosion resistance. A receiving groove 011 is formed within the housing 01, extending along the length of the housing 01 through one side wall. The groove has a rectangular cross-section, its dimensions matching those of the internally assembled rotating body 03, PCB board 08, and other components, providing stable installation space for each core component.

[0094] Please return to the reference. Figure 9 The housing 01 consists of three parts: a base 014, a lower cover 015, and an upper cover 016. The base 014 is located between the upper cover 016 and the lower cover 015 and has a cylindrical structure. The lower cover 015 is placed on the bottom of the base 014 and is fixedly connected to the base 014 by a threaded part 16. The inner side of the lower cover 015 has a PCB board 08 mounting groove with a depth of about 2mm for fixing the PCB board 08.

[0095] Please refer to Figure 10 and Figure 11 The top cover 016 is fastened to the top of the base 014 and connected to the base 014 by a threaded part 16, which facilitates disassembly and maintenance. Corresponding positions of the base 014 and the top cover 016 have through grooves, which together form the main part of the receiving groove 011. An annular snap-fit ​​groove 017 is formed between the base 014 and the top cover 016 for fixing the end of the flexible protective sleeve 15. The threaded part 16 passes through the base 014, the flexible protective sleeve 15 and the top cover 016 to fix this part of the structure.

[0096] Please refer to Figure 11 In addition, the inner wall of the shell 01 extends inward near the opening of the receiving groove 011 to form an annular boss 012. The annular boss 012 and the shell 01 are integrally formed. Its inner diameter is larger than the diameter of the rod 05, ensuring that the rod 05 can pass through the annular boss 012 and that the rod 05 can generate a certain rotation angle in each direction.

[0097] Please refer to Figure 11 The annular boss 012 forms a clearance arc surface 018 on one side of the rotating body 03 to avoid interference between the rotating body 03 and the annular boss 012 during rotation, thus ensuring the flexible rotation of the rotating body 03.

[0098] Please refer to Figure 12 In some examples, the outer shaft 02 can be made of 45 steel, which is heat-treated to have high strength and wear resistance, and is cylindrical in shape. There are two outer shafts 02, which are coaxially arranged and located in the receiving groove 011, and are fixed to the housing 01 along the opening direction perpendicular to the receiving groove 011.

[0099] Please refer to Figure 12 Specifically, one end of the outer rotating shaft 02 is embedded in the preset mounting hole in the rotating ring 09 by an interference fit, and the other end extends into the receiving groove 011 and is fixed relative to the position of the outer shell. A gap is left between the ends of the two outer rotating shafts 02 away from the inner wall of the receiving groove 011. This gap provides space for the installation of the rotating body 03 and avoids motion interference between the outer rotating shaft 02 and the rotating body 03.

[0100] Please refer to Figure 12 The outer rotating shaft 02 and the rotating body 03 are rotatably connected. Circular through holes are opened on both sides of the rotating body 03 corresponding to the position of the outer rotating shaft 02. The diameter of the through holes is slightly larger than the diameter of the outer rotating shaft 02, so that the rotating body 03 can rotate smoothly around the axis of the outer rotating shaft 02. The rotation angle range can be designed as needed to meet the angle adjustment requirements of the handle in this direction.

[0101] Please refer to Figure 12 In some examples, the rotating body 03 can be injection molded from polyoxymethylene, thus possessing excellent self-lubricating properties and fatigue resistance, or it can be machined from metal, thus possessing high strength and lifespan. The overall shape of the rotating body 03 is a hollow square structure, and the cavity formed inside is the rotation space. The size of the rotation space is sufficient to accommodate the assembly of the rod 05 and the inner rotating shaft 04.

[0102] Please refer to Figure 12 Cylindrical grooves are provided on the outer walls of both sides of the rotating body 03 corresponding to the positions of the outer rotating shaft 02. The diameter of the grooves is adapted to the diameter of the outer rotating shaft 02. The outer rotating shaft 02 extends into the grooves to realize the rotational connection between the rotating body 03 and the outer rotating shaft 02.

[0103] Please refer to Figure 12 The rotating body 03 is positioned between the two outer rotating shafts 02 and located inside the receiving groove 011. A gap is left between the rotating body 03 and the inner wall of the receiving groove 011 to prevent friction between the rotating body 03 and the housing 01 when it rotates. At the same time, two opposing mounting holes are opened on the inner wall of the rotating body 03 corresponding to the position of the inner rotating shaft 04. The mounting holes are opened radially along the rotating body 03 and are used to install the inner rotating shaft 04 to provide support for the rotation of the rod 05.

[0104] Please refer to Figure 12 In some examples, the inner rotating shaft 04 can be made of stainless steel, which has good corrosion resistance and toughness. It is cylindrical in shape, and its length is slightly larger than the dimension of the rotating body 03 in that direction, ensuring that the inner rotating shaft 04 can pass through the rotation space of the rotating body 03.

[0105] Please refer to Figure 12 The axis of the inner rotating shaft 04 is perpendicular to the axis of the outer rotating shaft 02, and the axis of the inner rotating shaft 04 is perpendicular to the opening direction of the receiving groove 011, forming a cross shape. This layout allows the handle to achieve angle adjustment in two vertical directions, expanding the operation dimensions.

[0106] Please refer to Figure 12 Please refer to Figure 12The inner rotating shaft 04 and the rotating body 03 can be fixedly connected and installed in the mounting holes on both sides of the rotating body 03 by interference fit. After installation, the two ends of the inner rotating shaft 04 are flush with the outer wall of the rotating body 03 to avoid interference between the protruding part and other components.

[0107] Please refer to Figure 12 Meanwhile, the inner rotating shaft 04 and the rod body 05 are rotatably connected. The rod body 05 has a transverse through hole at the position corresponding to the inner rotating shaft 04. The diameter of the hole is slightly larger than the diameter of the inner rotating shaft 04, so that the rod body 05 can rotate freely around the inner rotating shaft 04 in the rotating body 03. The rotation angle range can also be designed as needed. In addition, along the axis perpendicular to the inner rotating shaft 04, there is a gap between the rod body 05 and the inner wall of the rotating body 03, which further ensures the flexibility of the rod body 05 rotation.

[0108] Alternatively, the inner pivot 04 and the rod body 05 can be integrally formed, with the inner pivot 04 formed by an integral protrusion on the rod body 05, which can achieve the same effect.

[0109] Please refer to Figure 13 In some examples, the rod 05 can be made of aluminum alloy, which is lightweight and strong, and has an overall cylindrical structure. The rod 05 passes through the rotating body 03 along the opening direction of the receiving groove 011. One end of the rod extends from the opening of the receiving groove 011 of the housing 01 to the outside of the housing 01 for mounting the handle 14; the other end extends into the receiving groove inside the housing 01. The end is left with a certain distance from the lower cover 015 for fixing the magnet disk 06 and leaving space for the PCB board 08 and the Hall chip 07.

[0110] Please refer to Figure 13 The rod 05 and the rotating body 03 are rotatably connected by the inner rotating shaft 04. There is a gap between the rod 05 and the annular boss 012, and a gap is also left between the rod 05 and the inner wall of the rotating body 03 to ensure that the rod 05 is not obstructed during rotation.

[0111] In addition, the part of the rod body 05 located outside the housing 01 can be provided with an internal thread 051 for connecting with the external thread 141 of the handle 14 to achieve the fixed installation of the handle 14; a circular groove is provided at one end of the rod body 05 near the magnet disk 06, the diameter of the groove can be larger than or equal to the diameter of the magnet disk 06, so as to accommodate and fix the magnet disk 06 and ensure the synchronous movement of the magnet disk 06 and the rod body 05.

[0112] Please refer to Figure 13 In some examples, the magnetic disk 06 can be made of neodymium iron boron strong magnetic material, with a nickel-plated surface to prevent rusting. Its shape can be designed as a circle, ring, or multiple regularly arranged rings according to actual needs.

[0113] Please refer to Figure 13 The magnet disk 06 is fixedly installed at one end of the rod 05 within the receiving groove. It can be fixed to the circular groove at the end of the rod 05 by strong adhesive. The magnet disk 06 can be partially or completely installed within the rod 05. Alternatively, the groove depth can be slightly less than the thickness of the magnet disk 06, allowing part of the magnet disk 06 to be embedded in the rod 05 while the other part is exposed. This ensures a stable connection between the magnet disk 06 and the rod 05, while also creating a reasonable magnetic field range between the magnet disk 06 and the Hall chip 07, ensuring that the Hall chip 07 can accurately detect the rotation angle of the rod 05.

[0114] Please refer to Figure 13 In some examples, the Hall chip 07 is capable of accurately detecting changes in magnetic fields and converting them into electrical signals. Please refer back to the reference. Figure 1 The Hall chip 07 is located in the receiving slot 011 and is specifically installed on the surface of the PCB board 08. It is connected to the circuit of the PCB board 08 by surface mount soldering to ensure stable signal transmission.

[0115] Along the axial direction of the rod 05, the Hall chip 07 is located on the outside of the rod 05 and is distributed at intervals with the magnet disk 06. The distance between the two can be 2-5mm. This distance can ensure that the Hall chip 07 is within the effective magnetic field range of the magnet disk 06, and can also avoid physical contact between the two to prevent mutual wear.

[0116] The Hall chip 07 is directed towards the magnet disk 06. When the rod 05 drives the magnet disk 06 to rotate, the relative position between the magnet disk 06 and the Hall chip 07 changes, and the magnetic field strength changes accordingly. The Hall chip 07 converts the magnetic field change into a voltage signal, which is transmitted to the external device control system through the circuit on the PCB board 08 to realize the angle detection function.

[0117] Please refer to Figure 1 In some examples, PCB board 08 can be made of FR-4 epoxy resin glass cloth substrate 08PCB, with a thickness of approximately 1.6mm, and its dimensions are adapted to the mounting slot of the lower cover 015. The corresponding circuits are printed on PCB board 08, including the power supply circuit for Hall chip 07, signal amplification circuit, and signal output interface. The interface type is PH2.0-4P, which is used to connect to the control line of external devices.

[0118] Please refer to Figure 1The PCB board 08 is housed within the receiving slot 011, specifically within the mounting slot of the lower cover 015. It is secured to the lower cover 015 via two threaded fittings 16, ensuring the stability of the PCB board 08 within the housing 01. A Hall effect chip 07 is soldered onto the surface of the PCB board 08. The pins of the Hall effect chip 07 are connected to the circuitry on the PCB board 08 via wires. The PCB board 08 also has pre-drilled positions for components such as filter capacitors and resistors to optimize circuit performance, reduce signal interference, and ensure the accuracy and stability of the signal detected by the Hall effect chip 07.

[0119] Please refer to Figure 1 After the PCB board 08 and Hall chip 07 are arranged, they can be further sealed by encapsulation to ensure the connection stability between Hall chip 07 and PCB board 08.

[0120] Please refer to Figure 1 Corresponding pin terminals can be configured on the outside of PCB board 08 to facilitate the output of signals from PCB board 08 and to facilitate the power supply of PCB board 08; the pin terminals can be configured on the outside of the lower cover 015 of the housing.

[0121] Please refer to Figure 2 In some examples, the rotating ring 09 can be made of brass and is shaped as a square ring with rounded corners. The rotating ring 09 is disposed inside the annular boss 012 and is fixed relative to the housing 01. Specifically, it can be fixedly connected to the annular boss 012 and the pad 12 through the threaded connector 13 to ensure that the rotating ring 09 is stable inside the housing 01.

[0122] Please refer to Figure 2 The threaded connector 13 between the annular boss 012 and the pad 12 can be configured as 2 sets, 3 sets, or 4 sets. The threaded connector 13 can be the same as the threaded part 16, for example, both can be bolts and nuts, or can be configured with threaded sleeves to facilitate fixing and installation.

[0123] Please refer to Figure 2 The gap between the inner wall of the rotating ring 09 and the outer wall of the rotating body 03 prevents friction between the rotating body 03 and the rotating ring 09 when the rotating body 03 rotates. Mounting holes are provided on both sides of the rotating ring 09 corresponding to the positions of the outer rotating shaft 02. The diameter of the holes is adapted to the diameter of the outer rotating shaft 02. One end of the outer rotating shaft 02 is inserted into the mounting hole to realize the fixed connection between the outer rotating shaft 02 and the rotating ring 09, thereby stably supporting the outer rotating shaft 02 inside the housing 01.

[0124] Please refer to Figure 6In some examples, the reset ring 10 can be made of polytetrafluoroethylene (PTFE), which has excellent self-lubricating properties and corrosion resistance. The reset ring 10 can be cylindrical with a partially spherical surface. The reset ring 10 is slidably connected to the rod 05 along the axial direction of the rod 05, that is, the reset ring 10 is sleeved on the outside of the rod 05, and a gap can be left between them, so that the reset ring 10 can rotate freely around the rod 05 and slide along the axial direction of the rod 05.

[0125] Please refer to Figure 5 and Figure 6 The reset ring 10 abuts against the reference plane 013 of the annular boss 012, and the part of the reset ring 10 that abuts against the reference plane 013 forms an arc surface 101. The arc surface 101 can reduce the friction area between the reset ring 10 and the reference plane 013 and reduce the friction resistance. The arc surface at the bottom of the reset ring 10 can together form a spherical surface.

[0126] Alternatively, a guide groove and a guide protrusion can be added to the connection between the reset ring 10 and the rod 05, so that the reset ring 10 can only slide along the axis of the rod 05, thus preventing the reset ring 10 and the rod 05 from rotating relative to each other.

[0127] Please refer to Figure 6 The return spring 11 can be made of piano wire. The return spring 11 is sleeved on the rod 05 and located between the return ring 10 and the handle 14. One end of the return spring 11 abuts against the side of the return ring 10 away from the reference plane 013, and the other end is fixed relative to the end of the rod 05 located outside the housing 01.

[0128] Specifically, the portion of the rod 05 located outside the housing 01 may have an annular protrusion. The other end of the return spring 11 abuts against this annular protrusion, ensuring that the return spring 11 can provide a stable elastic force. Alternatively, the return spring 11 may directly abut against the handle 14, forming a compression through the end of the handle 14. When the rod 05 is rotated under force, the return spring 11 is compressed, generating an elastic force. When the external force is removed, the elastic force of the return spring 11 pushes the return ring 10, thereby driving the rod 05 back to its initial position, realizing the automatic reset function.

[0129] Please refer to Figure 6 In some examples, the pad 12 can be made of polyimide, which is resistant to high temperatures and wear. The shape of the pad 12 can be annular. The pad 12 is disposed between the reset ring 10 and the reference plane 013 of the annular boss 012, and is fixedly connected to the annular boss 012. Specifically, it is fixed together with the annular boss 012 and the rotating ring 09 through the threaded connector 13 to ensure that the pad 12 will not be displaced during use.

[0130] A gap needs to be set between the pad 12 and the rod 05 to ensure the smooth rotation of the rod 05. Therefore, the middle part of the pad 12 can be a cylindrical hole.

[0131] Please refer to Figure 6 The main function of the pad 12 is to isolate the reset ring 10 from the annular boss 012, preventing the reset ring 10 from wearing down the reference plane 013 of the annular boss 012 during long-term reciprocating motion. At the same time, by selecting pads 12 of different thicknesses or materials, the gap and friction between the reset ring 10 and the annular boss 012 can be finely adjusted, thereby adjusting the reset force of the handle to adapt to the operating preferences of different users or the needs of different application scenarios.

[0132] For example, in industrial equipment, a thicker pad 12 can be used to increase the reset force and ensure quick reset after operation; in game controllers, a thinner pad 12 can be used to reduce the reset force and improve the operating feel.

[0133] Please refer to Figure 7 In some examples, the threaded connector 13 can be made of stainless steel and can be an internal hexagonal head screw. The specifications can be selected according to the needs of the connection part. The threaded connector 13 connecting the rotating ring 09, the annular boss 012 and the pad 12 can be M3×8mm. The threaded connector 13 connecting the lower cover 015 and the base 014 can be M3×5mm.

[0134] Please refer to Figure 7 The number of threaded connectors 13 can be set to 1, 2 or 4 according to actual needs. If there is 1, it is set directly above the rotating ring 09, which is suitable for scenarios with small force. If there are 2, they are symmetrically set on both sides of the rotating ring 09 with an included angle of 180°, which is suitable for scenarios with medium force. If there are 4, they are evenly distributed in the circumferential direction of the rotating ring 09 with an included angle of 90°, which is suitable for scenarios with large force and high requirements for connection stability, such as the operating handle of heavy industrial equipment.

[0135] Please refer to Figure 7 The threaded connector 13 passes through the rotating ring 09, the annular boss 012, and the pad 12, and the three are tightly fixed together as a whole through the threaded engagement. This prevents the components from loosening or shifting under complex working conditions such as frequent rotation of the handle and stress. At the same time, the threaded connection method facilitates disassembly. When it is necessary to repair or replace the internal components, simply use an Allen wrench to unscrew the threaded connector 13 to separate the relevant components, thereby improving maintenance efficiency.

[0136] Please refer to Figure 8In some examples, the handle 14 can be made of a composite of TPR soft rubber and ABS plastic. The outer layer is TPR soft rubber, which has good elasticity and anti-slip properties, and a comfortable feel; the inner layer is ABS plastic, which ensures the structural strength of the handle 14. The overall shape of the handle 14 can be cylindrical, and the surface can be provided with anti-slip textures. The textures can be diagonal stripes to further enhance the friction when gripping and prevent slippage.

[0137] Please refer to Figure 8 The handle 14 is fixedly installed at one end of the rod 05 outside the housing 01. Specifically, it can be fixed by a threaded connection. For example, an external thread 141 can be opened on the outside of the handle 14 to connect with the internal thread 051 at the end of the rod 05. After tightening, it can be further reinforced with strong adhesive to ensure that there is no relative rotation or loosening between the handle 14 and the rod 05.

[0138] Please refer to Figure 8 The axis of handle 14 can be aligned with the axis of rod 05, making it convenient for the operator to grip and apply force. Whether making large angle adjustments or fine motion control, it can be operated precisely through handle 14. It is especially suitable for scenarios that require frequent operation of the handle, such as game controllers, medical device control handles, etc.

[0139] Please refer to Figure 8 In some examples, the flexible protective sleeve 15 can be made of silicone material, so that it can maintain stable performance in a temperature range of -40℃ to 200℃. The shape of the protective sleeve can be a cylindrical corrugated tube structure with an inner diameter larger than the diameter of the rod 05. The flexible protective sleeve 15 does not contact the rod 05, and there is a gap between the two to prevent the protective sleeve from affecting the rotation of the rod 05.

[0140] Please refer to Figure 8 and Figure 9 One end of the flexible protective sleeve 15 is fixedly connected to the handle 14, specifically by a clamping method. That is, the end of the protective sleeve is fitted onto the side of the handle 14 near the housing 01, and reinforced with a clamping ring to ensure a tight connection and prevent dust and moisture from entering from the connection point. The other end is fitted onto the housing 01, specifically by embedding it into the annular snap-fit ​​groove 017 between the base 014 and the top cover 016, and is fixedly connected by threaded parts 16. There can be 4 threaded parts 16, which are evenly distributed on the outside of the annular snap-fit ​​groove 017 to press and fix the end of the flexible protective sleeve 15 into the annular snap-fit ​​groove 017, thereby achieving a sealed connection between the flexible protective sleeve 15 and the housing 01.

[0141] The flexible protective cover 15 can not only effectively prevent dust, moisture, and debris from entering the handle, thus preventing internal components such as the PCB board 08, Hall chip 07, and hinge from rusting or short-circuiting due to external environmental factors and extending the handle's service life, but also improve the handle's appearance and texture, making it more user-friendly.

[0142] Meanwhile, if the handle is accidentally dropped during transportation, the corrugated structure of the flexible protective sleeve 15 can act as a buffer, absorbing the impact force and reducing the damage caused by the handle colliding with the ground or other objects, thus reducing the risk of damage to the handle and preventing injury to people around when the handle falls.

[0143] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0144] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
