Description

Technical Field

[0001] The present application relates to the technical field of rockers, and in particular to a detachable rocker. Background Art

[0002] A game controller is an input device for an electronic game console. By operating its buttons and joysticks, etc., you can control simulated characters in game consoles, computers, and smart devices. Among them, joysticks are widely used in game handles. By operating the joysticks, you can control game consoles, computers, and smart devices.

[0003] At present, the structure of common game joysticks is generally realized by dual potentiometers, and two rocker potentiometers are generally used to realize two-axis (X, Y) analog output. The working principle of the rocker potentiometer is: by shaking the rocker of the rocker potentiometer, the brush mechanism of the rocker potentiometer is driven to adjust the resistance value of the rocker potentiometer, and the output current is changed by changing the resistance value. This type of rocker potentiometer structure belongs to a mechanical rocker structure, and the physical contact is easy to wear, resulting in reduced button sensitivity, which ultimately leads to a short service life and a reduced user control experience. Summary of the invention

[0004] The purpose of the present application is to provide a detachable rocker with a longer service life.

[0005] A detachable joystick provided in the present application adopts the following technical solution: a detachable joystick, comprising a control rod, a universal joint, a capacitor plate and a conductive member; the control rod is rotatably connected to the universal joint, the conductive member is arranged at one end of the control rod, and the conductive member and the capacitor plate sense each other.

[0006] By adopting the above technical solution, the setting of the rotational connection between the control rod and the universal joint enables the control rod to be moved, thereby satisfying the function of the joystick; and the capacitor glue on the control rod and the capacitor plate sense each other, so in the process of moving the control rod, the static electricity on the user's finger is transmitted to the conductive part through the control rod, causing the induced capacitance value between the conductive part and the conductive layer of the capacitor plate to change, and the control function can be realized by the change of the capacitance value.

[0007] Optionally, it also includes a bottom plate, a surface shell and a limiting base, wherein the limiting base is detachably connected to the bottom plate and the surface shell on two opposite sides respectively; a first opening is opened on one side of the surface shell, the universal joint is arranged in the surface shell, the control rod is inserted into the first opening, and the universal joint is rotatably connected to the inner wall of the surface shell.

[0008] By adopting the above technical solution, the setting of the face shell and the bottom plate constitutes the outer shell of the rocker, providing space for the installation of the rocker, universal joint and capacitor plate. Through the setting of the limit base, the two opposite sides of the limit base are detachably connected to the bottom plate and the face shell, respectively, so that the face shell and the bottom plate can be independently removed from the limit base, so that when the internal parts of the face shell are damaged, the face shell can be removed from the limit bottom plate and the parts can be replaced. At this time, the bottom plate and the limit base are still connected to each other, which is convenient for the assembly of the rocker after the parts are replaced; when the parts in the bottom plate are damaged, the effect is the same. Therefore, when maintaining or replacing a damaged single component, only the damaged position can be removed, which reduces the difficulty of replacing a single part and facilitates the assembly of the rocker after the parts are replaced.

[0009] Optionally, the capacitor plate is electrically connected to a PCB board.

[0010] By adopting the above technical solution, the PCB board can detect the change of the induced capacitance value between the capacitor plate and the conductive member. After the PCB board detects the change of the induced capacitance value, the action performed by the control stick at this time can be determined according to the changed capacitance value, thereby realizing the control function of the joystick.

[0011] Optionally, a limiting hole is formed through the face shell, a connecting hole is formed through the bottom plate, and a first connecting column and a second connecting column are respectively provided on both sides of the limiting base along the thickness direction, the first connecting column is plug-fitted with the limiting hole, and the second connecting column is plug-fitted with the connecting hole.

[0012] By adopting the above technical solution, the plug-in cooperation between the first connecting column and the limiting hole and the plug-in cooperation between the second connecting column and the connecting hole realizes the detachable connection between the limiting base and the surface shell and the bottom plate.

[0013] Optionally, a control console and a return-to-center spring are provided on the outer side of the control rod, the control console and the return-to-center spring are both arranged in the surface shell, and the return-to-center spring is arranged between the control console and the base plate.

[0014] By adopting the above technical solution, the console and the return spring are arranged, when the control rod is toggled, the control rod can contact the console and compress the return spring; after the control rod is toggled, the return spring will reset along the thickness direction of the bottom plate, so that the return spring can contact the console to reset, and then the console will drive the control rod to reset. Therefore, one return spring can realize the return to the center of the control rod, greatly reducing the number of elastic parts inside the face shell for controlling the reset, thereby reducing the required space inside the face shell and reducing the volume of the rocker.

[0015] Optionally, a mounting column is provided on the limiting base, and the mounting column is axially arranged along the height direction of the surface shell. A sliding hole is opened on the console along the height direction of the surface shell, and the sliding hole is plug-fitted with the mounting column, and the mounting column is slidably connected to the inner wall of the sliding hole along the axial direction of the mounting column; the control rod is inserted into the sliding hole, and the control rod is spaced apart from the side wall of the sliding hole.

[0016] By adopting the above technical solution, the sliding hole on the console is plugged and slidably connected with the mounting column through the sliding hole. Therefore, the control rod drives the console during the toggling process, which is converted into the axial movement of the console along the mounting column, which is convenient for compressing the return spring and facilitating the resetting effect of the return spring on the control rod.

[0017] Optionally, a resistance plate is arranged on the outer side of the control rod, and the resistance plate is arranged along the control rod on a side of the console away from the bottom plate, and the resistance plate and the console are in resistance to each other.

[0018] By adopting the above technical solution, since the control rod and the inner wall of the sliding hole are arranged at a certain interval, when the control rod is slightly moved, it is difficult for the control rod to conflict with the control console in time.

[0019] Based on the above problem, a contact plate is provided on the control rod, and the contact plate and the control console abut against each other along the axial direction of the control rod. When the control rod is moved, the contact plate abuts against the control console, driving the control console to slide. After the control rod is moved, the control console will reset the contact plate under the action of the return spring, so that the control rod can be reset in time.

[0020] Optionally, a mounting hole is formed on the mounting column along its axial direction; a first rotating shaft is coaxially arranged on two relatively outer side walls of the universal joint, and the first rotating shaft is rotatably connected to the inner side wall of the mounting hole.

[0021] By adopting the above technical solution, the mounting hole provided on the mounting column cooperates with the first rotating shaft on the universal joint, thereby realizing the toggling function of the control rod in one direction.

[0022] Optionally, a fixing plate is provided on the limiting base, and two rotating shaft seats are relatively provided on the fixing plate; two limiting grooves are relatively provided on the inner wall of the mounting hole, and the limiting grooves penetrate the inner wall of the mounting hole along the axial direction of the mounting hole; the limiting grooves are arranged in a one-to-one correspondence with the rotating shaft seats, and the rotating shaft seats are plugged and matched with the corresponding limiting grooves along the axial direction of the mounting column;

[0023] When the shaft seat is plugged into the corresponding limiting groove, the shaft seat is spaced apart from the inner wall of the limiting groove along the axial direction of the mounting hole, and the first rotating shaft is disposed in the space between the corresponding inner wall of the limiting groove and the shaft seat.

[0024] By adopting the above technical solution, after the rotating shaft seat on the fixed plate is plugged into the corresponding limiting groove, the gap between the rotating shaft seat and the limiting groove forms a space for installing the first rotating shaft. On the one hand, it ensures that the universal joint can rotate with the first rotating shaft as the central axis. On the other hand, since the rotating shaft seat and the limiting groove are installed by plugging, it is convenient to install and disassemble the first rotating shaft.

[0025] Optionally, a clearance hole is formed through the universal joint, and the control rod is plugged into the clearance hole; a second rotating shaft is coaxially arranged on two opposite side walls of the clearance hole, and the axial direction of the second rotating shaft is perpendicular to the axial direction of the first rotating shaft;

[0026] The control rod is provided with rotation holes on opposite sides, the rotation holes are arranged in one-to-one correspondence with the second rotation shaft, the second rotation shaft is plugged and matched with the rotation holes and is rotationally connected; the side wall of the clearance hole is spaced apart from the outer side wall of the control rod.

[0027] By adopting the above technical solution, the setting of the clearance hole on the universal joint provides a connection space between the universal joint and the control rod; the setting of the second rotating shaft set on the inner wall of the clearance hole can realize the movement of the control rod in another direction through the cooperation between the second rotating shaft and the control rod.

A capacitor plate 3 is provided on one side of the bottom plate 21 along its own thickness direction, the conductive member 5 is provided toward the capacitor plate 3, and a PCB board 4 is provided on the other side of the bottom plate 21 along its own thickness direction, and the PCB board 4 is electrically connected to the capacitor plate 3.

[0050] The arrangement of the face shell 22 and the base plate 21 provides a mounting body for the control assembly 1, and the control rod 11 can be moved inside the face shell 22 through the universal joint 12. In the process of moving the control rod 11, the static electricity on the user's finger is transmitted to the conductive member 5 through the control rod 11, thereby causing the induced capacitance value between the conductive member 5 and the conductive layer of the capacitor plate 3 to change. At this time, after the PCB board 4 detects the change in the induced capacitance value, it can determine the action performed by the control rod 11 at this time according to the changed capacitance value, thereby realizing the control function of the joystick.

[0051] Reference Figure 2 and Figure 3 The side of the surface shell 22 facing the bottom plate 21 is provided with a second opening 222, and the bottom plate 21 closes the second opening 222. The second opening 222 can reduce the distance between the conductive member 5 and the capacitor plate 3 on the bottom plate 21, thereby improving the sensitivity of the joystick.

Thus, the first mounting groove 211 and the second mounting groove 212 can provide mounting positions for the capacitor plate 3 and the PCB board 4.

[0053] Reference Figure 2 and Figure 5 A limited base 23 is provided between the bottom plate 21 and the face shell 22. The limited base 23 is provided with a plurality of first connecting columns 231 on the side facing the face shell 22. The first connecting columns 231 are axially arranged along the height direction of the face shell 22. A plurality of limited holes 223 are provided on the side of the face shell 22 away from the bottom plate 21. The limited holes 223 penetrate through a side wall of the face shell 22 away from the bottom plate 21. The limited holes 223 are arranged one-to-one with the first connecting columns 231. The first connecting columns 231 are plugged in with the corresponding limited holes 223. Thus, the arrangement of the first connecting columns 231 and the limited holes 223 realizes the installation between the limited base 23 and the face shell 22. After the first connecting columns 231 are plugged in with the corresponding limited holes 223, the end face of the first connecting columns 231 is flush with the side face of the face shell 22 away from the bottom plate 21, thereby improving the flatness of the surface of the face shell 22.

Therefore, the arrangement of the support plates 233 can support the inside of the face shell 22 and increase the stability of the internal space of the face shell 22.

Therefore, through the arrangement of the first connection columns 231 and the limiting holes 223 and the second connection columns 232 and the connection holes 213, the limiting base 23 can realize the installation between the bottom plate 21 and the face shell 22; at the same time, such an installation method is also convenient for the disassembly and maintenance between the bottom plate 21, the limiting base 23 and the face shell 22.

The mounting post 234 is axially arranged along the height direction of the housing 22. A mounting hole 235 is provided on one axial side of the mounting post 234. The mounting hole 235 is arranged along the axial direction of the mounting post 234 and penetrates the mounting post 234 and the limiting base 23.

Thus, the influence of the setting of the fixing plate 13 on the distance between the conductive member 5 and the capacitor plate 3 can be reduced.

[0059] Reference Figure 6 and Figure 7 , first rotating shafts 121 are provided on the two opposite outer side walls of the universal joint 12, and the two first rotating shafts 121 are coaxially arranged; two rotating shaft seats 131 are provided on the fixed plate 13, the two rotating shaft seats 131 are arranged around the connecting hole 132 and the two rotating shaft seats 131 are arranged opposite to each other along the radial direction of the connecting hole 132; the rotating shaft seats 131 are arranged in a one-to-one correspondence with the first rotating shafts 121, and the end of the rotating shaft seat 131 away from the fixed plate 13 is in contact with the corresponding first rotating shaft 121, so that the rotating shaft seat 131 can support the corresponding first rotating shaft 121, so as to realize the rotation connection between the universal joint 12 and the fixed plate 13 with the first rotating shaft 121 as the central axis, thereby realizing the rotation of the control rod 11 in one direction.

[0060] Reference Figure 6 and Figure 7Two limiting grooves 236 are formed on the side wall of the mounting hole 235. The two limiting grooves 236 are arranged opposite to each other along the radial direction of the mounting hole 235. The limiting grooves 236 are formed along one side of the axial direction of the mounting column 234 and penetrate the limiting base 23. The limiting grooves 236 are arranged one by one with the rotating shaft seat 131. Along the axial direction of the mounting column 234, the rotating shaft seat 131 is plugged and matched with the corresponding first limiting groove 236. After the rotating shaft seat 131 is plugged and matched with the corresponding first limiting groove 236, the rotating shaft seat 131 is spaced from the inner wall of the corresponding first limiting groove 236 along one side of the mounting column 234. The first rotating shaft 121 is inserted into the gap between the corresponding rotating shaft seat 131 and the inner wall of the corresponding first limiting groove 236, and the side wall of the first rotating shaft 121 is rotatably connected with the inner wall of the corresponding limiting groove 236 and the rotating shaft seat 131. Therefore, the limiting groove 236 and the rotating shaft seat 131 limit the first rotating shaft 121 on the basis of ensuring that the first rotating shaft 121 can rotate, thereby improving the rotation stability of the universal joint 12 and facilitating the disassembly of the universal joint 12.

[0061] Reference Figure 7 and Figure 8 The universal joint 12 is provided with a clearance hole 122, and the two opposite side walls of the clearance hole 122 are provided with a second rotation axis 123, the two second rotation axes 123 are coaxially arranged, and the axial direction of the second rotation axis 123 is perpendicular to the axial direction of the first rotation axis 121.

The control rod 11 and the two inner side walls of the clearance hole 122 that are opposite to each other along the axial direction of the first rotation axis 121 are spaced from each other, and such a setting provides space for the control rod 11 to be moved. Therefore, through the matching setting of the first rotation axis 121 and the second rotation axis 123 on the universal joint 12, the control rod 11 can be moved in two directions, thereby satisfying the function of the rocker.

[0062] Reference Figure 5 and Fig. 9 The mounting column 234 is provided with a control console 14, and a sliding hole 142 is opened on the control console 14 along the height direction of the surface shell 22. The sliding hole 142 is plugged into the mounting column 234 and is slidably connected along the height direction of the surface shell 22. The mounting column 234 is also provided with a return spring 15, and the two ends of the return spring 15 in the length direction are respectively connected to the control console 14 and the limit base 23. Therefore, the return spring 15 can realize the automatic resetting of the control console 14.

Under the action of the return spring 15, the contact plate 111 contacts the control console 14 along one side of its thickness direction. Therefore, after the control rod 11 is moved, the return spring 15 contacts the control console 14 and contacts the contact plate 111 through the control console 14, thereby realizing automatic reset of the control rod 11.

[0064] Reference Figure 6 and Fig. 9 The outer wall of the console 14 is provided with a limiting protruding ring 143, and the limiting base 23 is provided with two limiting clamping plates 237, which are arranged opposite to each other along the axial direction of the mounting hole 235, and the length direction of the limiting clamping plates 237 is arranged along the height direction of the face shell 22, and a clamping block 238 is arranged at one end of the limiting clamping plate 237 away from the limiting base 23, and the clamping block 238 extends toward the mounting hole 235 and protrudes from the side wall of the limiting clamping plate 237 toward the mounting hole 235. When the console 14 slides axially along the mounting column 234, the clamping block 238 and the limiting protruding ring 143 are arranged to conflict with each other along the axial direction of the mounting column 234, so that the limiting clamping plate 237 can limit the sliding distance of the console 14.

[0065] Reference Figure 5 and Fig. 9 A plurality of auxiliary slide grooves 141 are provided on the outer wall of the console 14.

[0066] Reference Fig.10 A connecting portion 113 is provided on one end of the control rod 11 away from the conductive member 5. A plug hole 1131 is provided on the connecting portion 113 along the axial direction of the control rod 11. Two plug surfaces 1132 are provided on the connecting portion 113. The two plug surfaces 1132 are arranged opposite to each other along the axial direction of the control rod 11. The arrangement of the plug hole 1131 and the plug surface 1132 facilitates the installation of various key caps or lever caps on the control rod 11.

[0067] The implementation principle of the embodiment of the present application is: The working principle of the non-contact capacitive joystick is: there is an electric field between any two conductive objects. When a piece of material that has a greater impact on the electric field is brought into the electric field of the capacitor formed at the intersection of two conductive objects, the material will affect the capacitance of the capacitor, and this change can be detected by measurement.

[0068] By creating two arrays, X and Y, on the capacitor plate 3, when the user turns the control rod 11, the conductive member 5 and the capacitor plate 3 generate inductive capacitance. At this time, the coordinates of the position can be located according to the strongest inductive capacitance on the X and Y axes, and the position can be locked by inputting the two coordinates of the X and Y axes. That is, when the user turns one or more directions, a corresponding signal will be generated, which will be transmitted to the computer / game console through the MCU for analysis and calculation, thereby determining the moving direction and displacement.

[0069] A capacitive sensor is a grid of small electrodes, one of which is a transmitter and the other a receiver. They form a capacitor, and when a finger or other substance that affects the electric field is close, the capacitance changes. This change can be detected and measured, so that the position of the finger can be detected.

[0070] Based on the above principle, in the present application, after the control rod 11 is moved along the X-axis, Y-axis or Z-axis direction, the control console 14 moves toward the bottom plate 21 under the resistance of the resistance plate 111, and at the same time, the conductive member 5 at the lower end of the control rod 11 moves into the sensing area of ​​the capacitor plate 3 and generates a capacitive sensing signal of the corresponding position of the conductive member 5, thereby determining the moving direction and displacement. In the above process, after the control rod 11 is released, the return spring 15 automatically resists the control console 14 and moves toward the resistance plate 111. After the control console 14 resists the resistance plate 111, the control rod 11 can be reset to the middle position, realizing the automatic reset of the control rod 11.
