Description

Technical Field

[0001] This invention relates to the field of rocker technology, specifically to a gear-engaging multi-position adjustable rocker structure. Background Technology

[0002] In the field of electronic device control, joysticks, as important input components, are widely used in various products such as game controllers, virtual reality devices, and industrial control terminals. With the continuous development of related technologies, users have placed higher demands on the functionality, precision, and user experience of joysticks. A utility model patent, application number 202322583007.8 and authorization announcement number CN220821225 U, entitled "A Joystick Device," discloses a device comprising a housing, a PCB board, and a joystick. This device determines the joystick's swing direction using a Hall sensor or an integrated infrared transmitter and receiver. Although it employs non-contact adjustment to avoid some problems associated with contact adjustments, it lacks multi-level adjustment functionality, failing to meet the diverse needs of users for different operating sensitivities and strengths. Furthermore, its simple transmission structure makes it difficult to achieve high-precision operational feedback. The utility model patent, with application number 201921111660.1 and authorization announcement date of February 14, 2020, entitled "A Stable Rocker Potentiometer," mainly uses the cooperation of upper and lower rocker arms to ensure good verticality of the rocker after reset. However, this potentiometer lacks a multi-level adjustment mechanism, resulting in insufficient diversity in operating modes. Furthermore, its signal detection and transmission methods are relatively traditional, exhibiting poor stability in complex environments, and lacking optimized design of the gear meshing transmission structure, making precise operation control difficult. Currently available rocker structures mostly suffer from the following problems: firstly, limited level adjustment functionality, unable to flexibly adjust operating parameters according to different usage scenarios; secondly, insufficient precision and stability of the gear transmission structure, leading to stuttering or deviation during operation; thirdly, insufficient stability and accuracy of signal detection and transmission, affecting the device's response performance; and fourthly, deficiencies in ergonomic design, easily causing user fatigue during prolonged use. Therefore, developing a gear-engagement multi-position adjustable rocker structure with precise multi-position adjustment, stable transmission, reliable signal transmission, and a good user experience is of great practical significance. Summary of the Invention

[0003] The purpose of this invention is to provide a gear-engaging multi-position adjustable rocker structure to solve the problems mentioned in the background art, such as single-position adjustment function, unstable transmission structure, unreliable signal transmission, and poor user experience.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a gear-engaging multi-position adjustable rocker structure, comprising a rocker base, a rocker body, a rotating sleeve, and an internal gear transmission assembly, etc. The rocker base is provided with a base mounting hole, and a conical rubber positioning sleeve is provided inside the base mounting hole. A button cap is installed on the upper part of the rocker body, and a circular groove is provided below it. The rotating sleeve is connected to the rocker body through a connecting block, and the internal thread groove on the inner wall of the rotating sleeve engages with the external thread post on the rocker body. The rotating sleeve can rotate and move relative to the rocker body. A bottom fixing plate is provided at the bottom of the rotating sleeve, and an anti-slip textured sleeve is provided on the outer side. An inner fixing ring frame is also provided inside the rocker base. A Hall sensor is installed on the inner fixing ring frame for detecting the rocker's action signal, and a plug-in interface is provided for circuit connection and signal transmission.

[0005] As a preferred embodiment of the present invention, the bottom of the rocker body is connected to the large bevel gear via a key connection assembly. The large bevel gear meshes with the side bevel gear and the auxiliary bevel gear respectively. The side bevel gear and the auxiliary bevel gear are mounted on the connecting shaft and are driven by the meshing of the gears.

[0006] As a preferred embodiment of the present invention, one end of the connecting shaft is connected to a small gear, the small gear meshes with a fixed gear, the fixed gear is mounted on a fixed rod, and the fixed rod is connected to a speed regulating gear.

[0007] As a preferred embodiment of the present invention, a positioning plate frame is provided on one side of the rocker base, an electromagnetic clutch is installed on the positioning plate frame, the electromagnetic clutch is connected to the adjustment plate, the adjustment plate is provided with a spring reset button and a positioning pin, the rocker base is provided with an annular positioning slot at a corresponding position and is controlled by the on / off state of the electromagnetic clutch, and the adjustment plate cooperates with the annular positioning slot.

[0008] As a preferred embodiment of the present invention, the bottom of the button cap is provided with a ring magnet, and the top of the rocker body is provided with an adsorption block, which is adsorbed by the magnetic force between the ring magnet and the adsorption block.

[0009] As a preferred embodiment of the present invention, the inner retaining ring frame provides fixed support for the Hall sensor and the plug-in interface, and is adapted to the internal structure of the rocker base.

[0010] As a preferred embodiment of the present invention, the internal gear structure of the speed regulating gear cooperates with the fixed gear on the fixed rod and the small gear on the connecting shaft.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The joystick body is connected to the large bevel gear via a key connection component at the bottom. The large bevel gear meshes with the side bevel gear and the auxiliary bevel gear. The small gear at one end of the connecting shaft meshes with the fixed gear and cooperates with the speed regulating gear. Compared with the simple transmission structure or lack of multi-gear adjustment design in the existing technology, this gear meshing transmission method can achieve more precise power transmission and multi-gear adjustment. Users can flexibly adjust the sensitivity and operation force of the joystick according to different usage scenarios, such as different operation modes in games or different precision requirements in industrial control, to meet diverse operation needs.

[0013] 2. By installing an inner retaining ring frame inside the rocker base, a Hall sensor mounted on it detects the rocker's motion signal using the Hall effect. Compared with the traditional potentiometer detection method or simple sensing element detection method used in some existing technologies, the Hall sensor is less affected by external interference and can more accurately detect changes in the rocker's motion. At the same time, the plug-in interface ensures the convenience and stability of signal transmission, avoiding problems such as signal loss or misjudgment, providing more reliable operating signals for the equipment, and improving the equipment's response effect and overall performance.

[0014] 3. The rotating sleeve features a bottom-fixed plate and an anti-slip textured sleeve on the outside, increasing friction for a more secure grip and preventing slippage. The rotating sleeve and joystick body can rotate and move relative to each other via an internal threaded groove and an external threaded post, increasing operational versatility and enjoyment. Furthermore, the button caps are magnetically attached to the joystick body using a ring magnet and an adsorption block, facilitating easy removal and replacement. Different styles or functions of button caps can be used according to user preferences or needs, addressing issues such as poor ergonomic design and fatigue during prolonged use in existing technologies, thus improving user comfort and convenience.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-6 This invention provides a gear-engaging multi-position adjustable rocker structure, comprising a rocker base 1, a rocker body 4, a rotating sleeve 7, and an internal gear transmission assembly. The rocker base 1 is provided with a base mounting hole 2, and a conical rubber positioning sleeve 3 is provided inside the base mounting hole 2. A button cap 5 is installed on the upper part of the rocker body 4, and a circular groove 6 is provided below it. The rotating sleeve 7 is connected to the rocker body 4 through a connecting block 8, and the internal thread groove 9 on the inner wall of the rotating sleeve 7 cooperates with the external thread post 10 on the rocker body 4. The rotating sleeve 7 can rotate and move relative to the rocker body 4. A bottom fixing plate 11 is provided at the bottom of the rotating sleeve 7, and an anti-slip textured sleeve 12 is provided on the outer side. An inner fixing ring frame 13 is also provided inside the rocker base 1. A Hall sensor 14 is installed on the inner fixing ring frame 13 for detecting the rocker's action signal, and a plug-in interface 15 is provided for circuit connection and signal transmission.

[0024] Specifically, the base mounting holes 2 on the joystick base 1 are used to securely install the entire joystick structure onto external devices using screws and other connecting components. The conical rubber positioning sleeve 3 inside the base mounting holes 2 utilizes the elastic deformation properties of rubber to provide precise positioning when the joystick body 4 is inserted, while also buffering the impact of external vibrations on the joystick, ensuring the accuracy and stability of the joystick's initial position. The rotating sleeve 7 is connected to the joystick body 4 via a connecting block 8, allowing them to be relatively fixed to a certain extent while also moving in tandem. The internal threaded groove 9 on the inner wall of the rotating sleeve 7 engages with the external threaded post 10 on the joystick body 4. When the rotating sleeve 7 is subjected to external force and rotates, due to the transmission action of the thread, the rotating sleeve 7 can rotate and move relative to the joystick body 4. For example, rotating the rotating sleeve 7 clockwise will cause it to move upwards along the joystick body 4 under the action of the thread, and vice versa. This movement and rotation can achieve some additional functional operations, such as switching between different operating modes or adjusting the joystick's sensitivity. The bottom fixing plate 11 of the rotating sleeve 7 enhances the structural stability of the rotating sleeve 7, while the outer anti-slip textured sleeve 12 increases friction, making the user's grip on the joystick more secure and less prone to slipping, thus improving the operating feel. The inner fixing ring 13 inside the joystick base 1 provides fixed support for the Hall sensor 14 and the plug-in interface 15. The Hall sensor 14 utilizes the Hall effect; when the joystick body 4 moves, the magnetic field around it changes, and the Hall sensor 14 can detect this change and convert it into an electrical signal, thereby realizing the detection of the joystick movement signal. The plug-in interface 15 is used to conveniently connect to external circuits, transmitting the detected signal to other devices for processing, ensuring the convenience and stability of signal transmission.

[0025] The bottom of the rocker arm body 4 is connected to the large bevel gear 17 via a keyed connection assembly 16. The large bevel gear 17 meshes with the side bevel gear 18 and the auxiliary bevel gear 19. The side bevel gear 18 and the auxiliary bevel gear 19 are mounted on the connecting shaft 20 and are driven by the meshing of the gears. The keyed connection assembly 16 ensures that the rotational motion of the rocker arm body 4 is accurately transmitted to the large bevel gear 17. When the rocker arm body 4 swings or rotates, it drives the large bevel gear 17 to rotate synchronously. The large bevel gear 17 meshes with the side bevel gear 18 and the auxiliary bevel gear 19. According to the gear transmission principle, the rotation of the large bevel gear 17 is transmitted to the side bevel gear 18 and the auxiliary bevel gear 19 through the meshing of the gear teeth. The side bevel gear 18 and the auxiliary bevel gear 19 are mounted on the connecting shaft 20, and their rotation drives the connecting shaft 20 to rotate together, thereby changing the direction and distributing the power of the rocker arm body 4, providing the basic power transmission for subsequent multi-gear adjustment and precise operation.

[0026] A pinion 21 is connected to one end of the connecting shaft 20. The pinion 21 meshes with a fixed gear 22, which is mounted on a fixed rod 23. The fixed rod 23 is connected to a speed regulating gear 24. The multi-stage transmission and speed regulation principle is as follows: The pinion 21 connected to one end of the connecting shaft 20 rotates along with the connecting shaft 20. The pinion 21 meshes with the fixed gear 22, and its rotation drives the fixed gear 22 to rotate through tooth meshing. The fixed gear 22 is mounted on the fixed rod 23, which is connected to the speed regulating gear 24. Through this series of gear transmissions, the rocker's operating force is further transmitted and converted. The speed regulating gear 24 has a specific gear structure that cooperates with the fixed gear 22 on the fixed rod 23 and the pinion 21 on the connecting shaft 20. Depending on the gear transmission ratio, the rocker's operating speed can be adjusted. For example, when a fast operation response is required, the transmission ratio can be adjusted by the speed regulating gear 24 so that the small movements of the joystick can be quickly transmitted and amplified; when precise fine-tuning is required, the transmission ratio can be adjusted to achieve more delicate operation control and meet the diverse requirements of joystick operation speed and precision in different usage scenarios.

[0027] A positioning plate frame 25 is provided on one side of the rocker base 1. An electromagnetic clutch 26 is mounted on the positioning plate frame 25. The electromagnetic clutch 26 is connected to an adjustment plate 27. The adjustment plate 27 is equipped with a spring reset button 28 and a positioning pin 29. A corresponding annular positioning groove 30 is provided on the rocker base 1, and the adjustment plate 27 cooperates with the annular positioning groove 30 through the on / off control of the electromagnetic clutch 26. The positioning plate frame 25 on one side of the rocker base 1 provides mounting support for the electromagnetic clutch 26. When the electromagnetic clutch 26 is energized, it generates a magnetic force, attracting the adjustment plate 27 to tightly cooperate with the annular positioning groove 30 on the rocker base 1. The positioning pin 29 on the adjustment plate 27 will insert into the corresponding slot of the annular positioning groove 30, thereby locking the current position of the rocker. At this time, the rocker can only be operated within the operating range corresponding to that position. When a gear shift is required, the electromagnetic clutch 26 is de-energized, the magnetic force disappears, the adjustment disc 27 resets under the action of the spring reset button 28, and the positioning pin 29 disengages from its current slot. The user can then operate the adjustment disc 27 to insert the positioning pin 29 into another slot. The electromagnetic clutch 26 is then re-energized to lock the new gear. This method enables the switching and locking of different joystick gears, meeting the user's needs for adjusting joystick operation parameters in different usage scenarios.

[0028] The button cap 5 has a ring magnet 31 at its bottom, and an adsorption block 32 at the top of the joystick body 4. The button cap and joystick body 4 are attracted to each other using magnetic force. The button cap is installed and removed by magnetic attraction between the ring magnet 31 and the adsorption block 32. When installing the button cap 5, simply bring it close to the top of the joystick body 4. Under the influence of the magnetic force, the ring magnet 31 and the adsorption block 32 will automatically adhere together, ensuring a secure installation. This installation method is simpler and faster than traditional clips or screws. When removing the button cap 5, simply apply a certain amount of external force to overcome the magnetic force between the ring magnet 31 and the adsorption block 32, and the button cap 5 can be easily removed, facilitating cleaning, replacement, or repair.

[0029] The inner retaining ring 13 provides fixed support for the Hall sensor 14 and the plug-in interface 15, and is adapted to the internal structure of the rocker base 1. The structural design of the inner retaining ring 13 is customized according to the internal space and shape of the rocker base 1, allowing it to be tightly installed within the rocker base 1. The inner retaining ring 13 provides stable fixed support for the Hall sensor 14 and the plug-in interface 15. During the operation of the rocker, it is subject to various external forces and vibrations. The inner retaining ring 13 ensures the positional stability of the Hall sensor 14 and the plug-in interface 15, preventing them from shifting or loosening. Simultaneously, the inner retaining ring 13 also provides a certain degree of shielding and protection, reducing the impact of external interference on the signal detection of the Hall sensor 14 and preventing physical damage to the plug-in interface 15, thereby ensuring the accuracy and reliability of signal detection and transmission, and guaranteeing the normal and stable operation of the entire rocker structure.

[0030] The internal gear structure of the speed regulating gear 24 meshes with the fixed gear 22 on the fixed rod 23 and the pinion 21 on the connecting shaft 20. The speed regulating gear 24 has a specific gear set structure, with carefully designed parameters such as the number of teeth and module. The fixed gear 22 on the fixed rod 23 and the pinion 21 on the connecting shaft 20 mesh with the internal gears of the speed regulating gear 24. When the rocker arm 4 moves, power is transmitted to the fixed gear 22 and pinion 21 through the preceding gear transmission structure, and then to the speed regulating gear 24. The gears inside the speed regulating gear 24 adjust the speed of the input power according to different transmission ratios. For example, when a slower rocker arm operation speed is needed for more precise fine-tuning, the gears inside the speed regulating gear 24 use a larger transmission ratio to reduce the input speed; when a faster response is needed, a smaller transmission ratio amplifies the input speed. Through the coordinated operation of this speed regulating gear 24 and other gears, the joystick operation speed can be flexibly adjusted to meet the diverse requirements of joystick operation sensitivity and speed in different usage scenarios, thereby improving the user's operating experience and the applicability of the equipment.

[0031] In this invention, the bottom of the rocker arm body 4 is securely connected to the large bevel gear 17 via a key connection assembly 16. When the rocker arm body 4 swings or rotates, its motion is transmitted to the large bevel gear 17 without reservation through the key connection assembly 16. The large bevel gear 17, with its teeth precisely meshing with the side bevel gear 18 and the auxiliary bevel gear 19, converts and distributes the power, driving the connecting shaft 20 to rotate. The pinion 21 at one end of the connecting shaft 20 rotates accordingly and meshes with the fixed gear 22, ultimately working in conjunction with the speed regulating gear 24. In this series of transmission processes, the precise meshing relationship between the gears ensures the accuracy and stability of power transmission. Unlike the simple or unoptimized transmission structures in the prior art, this invention can accurately convert the rocker arm's movements into corresponding outputs. Through the specific gear structure inside the speed regulating gear 24 and its cooperation with other gears, multi-speed adjustment can be achieved. For example, in gaming scenarios, players can adjust the settings according to different game types and operational needs. At lower settings, they experience a more stable and slower response, suitable for precise aiming; at higher settings, they can experience a more sensitive and faster response, meeting the demands of fast-paced action games. This precise multi-level adjustment greatly enhances the user's sense of control and accuracy, providing a richer and more personalized gaming experience. It effectively solves the problems of limited adjustment functionality and insufficient precision in existing technologies.

[0032] Inside the rocker base 1, the inner retaining ring 13 plays a crucial supporting and protective role. It provides a stable mounting base for the Hall sensor 14 and the plug-in interface 15, enabling them to maintain stable operation in complex environments. The Hall sensor 14 utilizes the advanced principle of the Hall effect to monitor the movement of the rocker body 4 in real time. When the rocker body 4 moves, the surrounding magnetic field changes, and the Hall sensor 14 can sensitively capture this change and quickly convert it into an electrical signal. Compared to traditional contact potentiometer adjustments or some simple inductive detection methods, the Hall sensor 14 has the advantage of non-contact detection, avoiding problems such as wear, breakage, and poor contact caused by long-term use, greatly enhancing the product's stability and lifespan. Meanwhile, the plug-in interface 15 employs a reliable circuit connection design, ensuring that the electrical signal detected by the Hall sensor 14 is transmitted quickly, stably, and accurately to other devices for processing. This entire signal detection and transmission system effectively avoids problems such as signal instability, susceptibility to interference, and unreliable transmission in existing technologies, providing the device with accurate and reliable operating signals. This allows the device to respond more accurately to user commands, improving overall device performance and user experience.

[0033] From an ergonomic perspective, the design of the rotating sleeve 7 fully considers the user's grip comfort. The bottom mounting plate 11 of the rotating sleeve 7 enhances structural stability, while the anti-slip textured sleeve 12 on the outer side increases friction with the user's hand, making the user's grip on the joystick more stable and less prone to slipping. Even during prolonged, high-intensity operation, the user can maintain a good grip, effectively reducing hand fatigue. In addition, the rotating sleeve 7 and the joystick body 4 are cleverly matched through the internal threaded groove 9 and the external threaded post 10, allowing the rotating sleeve 7 to rotate and move relative to the joystick body 4. This design not only increases the versatility of operation, allowing users to perform some quick operations or switch functions by rotating or moving the rotating sleeve 7, but also brings a unique operating experience to the user. A magnetic adsorption method is used between the ring magnet 31 and the adsorption block 32. This installation method is extremely convenient compared to traditional clip or screw fixing methods. When a user wants to replace button cap 5, they can easily remove it by simply applying a little external force to overcome the magnetism. During installation, simply place button cap 5 near the top of the joystick body 4, and it will automatically adhere and secure itself under magnetic force. Users can easily replace button caps with different styles and functions according to their preferences or the needs of different usage scenarios, further enhancing the product's personalization and ease of use. This solves problems such as insufficient ergonomic design and inconvenient component replacement in existing technologies, providing users with a more comfortable and convenient operating experience.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
