Description

Technical Field

[0001] The present invention relates to the technical field of game handles, and in particular to a joystick module, a joystick system and a game handle for timely detecting joystick sensing data. Background Art

[0002] With the development of economy, the popularity of mobile games has increased. Consumers who love mobile games usually buy game controllers to operate games, but traditional game controllers have many inconveniences in operating mobile games. The traditional game controller joystick is a two-potentiometer structure. They are the horizontal X-axis and the vertical Y-axis. The metal rod of the traditional game controller joystick is fixed to the shaft, the shaft is installed on the metal sheet on the metal shell, and the base is installed in the metal shell. The two-grid potentiometer is installed on the two fixed surfaces of the metal shell. When the metal rod shakes parallel to the shaft, the metal rod drives the metal sheet to rotate, and the metal sheet rotates the fixed potentiometer, causing the resistance value of the potentiometer to change; when the metal rod shakes perpendicular to the shaft, the metal sense drives the shaft to rotate, and the shaft rotates the fixed potentiometer, causing the resistance value of the potentiometer to change. The controller obtains the shaking state of the joystick through the change of the resistance value of the potentiometer. However, after the joystick is released, the shaft will not return to its original position immediately, resulting in the inability to monitor the release of the joystick in real time. This causes the problem of information transmission delay when the user shakes the joystick again. This problem brings a bad experience to users who have high requirements for gaming experience.

[0046] Embodiment 1

[0047] like Figure 1 The module framework diagram shown is a joystick module for timely detecting joystick sensing data disclosed in the present invention, comprising a control unit 100 and a joystick unit 200 electrically connected to the control unit 100;

[0048] The rocker unit 200 includes an active unit 201 for being shaken, a potential connection unit 202 connected to the active unit 201 at the same potential, and a surface potential subunit 203 connected to the potential connection unit 202 at the same potential, wherein the potential connection unit 202 is used to transmit the potential change of the active unit 201 when being shaken to the surface potential subunit 203;

[0062] Embodiment 2

[0063] like Figure 3 , 4As shown, the present invention also discloses a joystick system for timely detecting joystick sensing data, including a joystick module 400, a function button unit 500 electrically connected to the joystick module 400, an LED display unit 600 electrically connected to the joystick module 400, a power unit 700 electrically connected to the joystick module 400, a power supply unit 800 electrically connected to the joystick module 400, and a communication connection unit 900 electrically connected to the joystick module 400;

[0064] Among them, the joystick module 400 is the joystick module for timely detecting the joystick sensing data as described in any of the above items, so that the joystick system of this solution can achieve the beneficial effects of the above joystick module and can detect the shaking data of the sensing joystick in real time.

[0065] Specifically, the function button unit 500 , the LED display unit 600 , the power unit 700 , the power supply unit 800 , and the communication connection unit 900 are all connected to the control unit of the joystick module 400 .

[0066] As an optional implementation, when the joystick system is applied to a game controller, the number of the joystick modules 400 may be two, which are respectively disposed at the two ends of the game controller, but the two joystick modules 400 each use one control unit.

[0067] As an optional implementation, the function key unit 500 includes keys such as A, B, X, Y, L1, L2, R1, R2, etc. commonly used in game controllers.

[0068] As an optional implementation, the above-mentioned buttons are arranged in groups at the left and right ends of the game controller.

[0069] As an optional implementation, the LED display unit 600 includes an LED display lamp.

[0070] As an optional implementation, the power unit 700 may be a motor but is not limited to a motor. Specifically, the number of the power units may be 2, and when the joystick system is applied to a game controller, they are respectively disposed at both ends of the game controller.

[0071] As an optional implementation, the communication connection unit 900 may use a Bluetooth chip, a 4G data signal card, a 5G data signal card, a USB connection cable, etc.

[0072] As a preferred embodiment, the power supply unit 800 includes a battery, or a step-down circuit connected to a power supply, and the power supply unit 800 is used to supply working power to the joystick system.

[0073] like Figure 4In the illustrated embodiment, a schematic diagram of an implementation structure of a joystick system is shown. Specifically, the joystick system also includes a metal shell 1000 (corresponding to the surface potential subunit), a base connected to the metal shell 1000 (not shown in the figure, a base in the prior art is used to realize the rotation of the joystick), a first potentiometer 1001 installed on the metal shell 1000, a second potentiometer 1002 installed on the other side of the metal shell 1000, a rotating shaft 1003 installed inside the metal shell 1000 and connected to the first potentiometer 1001 and the second potentiometer 1002, a metal rod 1005 connected to the rotating shaft 1003 (corresponding to the movable unit), and a metal sheet 1004 (corresponding to the potential connection unit) installed on the rotating shaft 1003 and in contact with the metal rod 1005.

[0074] As an optional implementation, the second potentiometer 1002 includes pin A, pin B, and pin C, wherein pin A, pin B, and pin C correspond to the first pin, the second pin, and the third pin of the potentiometer unit, respectively, and are used to realize power input, data acquisition, and digital grounding effects, respectively.

[0075] As an optional implementation, the metal shell 1000 is provided with a protrusion 1006, and the protrusion 1006 is used to be electrically connected to the sensing unit of the joystick module.

[0076] In other implementations, the metal housing 1000 may be directly electrically connected to the sensing unit so that the sensing unit can obtain the potential information of the metal housing.

[0077] As an optional implementation, the metal housing 1000 is connected to the metal sheet 1004 at the same potential, and the metal sheet 1004 is connected to the metal rod 1005 at the same potential.

[0078] Since the metal shell 1000, the metal sheet 1004 and the metal rod 1005 are connected in a potential-conducting manner, the metal shell 1000 of the joystick is directly used as a sensing contact or sensing area through the principle of potential induction, so that the sensing chip of the sensing unit can collect the joystick sensing data, and by analyzing the collected sensing data, it is confirmed whether the hand shaking the joystick is released.

[0079] Among them, the potential conditions when the user does not release the joystick and the potential conditions when the joystick is released can be obtained according to the experiment. When the sensing chip receives the potential information, the potential information can be transmitted to the chip of the control unit through a number of logic gates and transistors, which directly realizes the timely detection of whether the hand shaking the joystick has released the joystick. Once the chip of the control unit receives the signal, it can immediately perform the corresponding operation (such as obtaining the potential information of the first potentiometer and the second potentiometer). Unlike the traditional joystick device, it does not need to wait until the joystick is released and then shaken again to start obtaining information. It expands the application scenarios of the joystick and can also improve the control experience of the game controller.

[0081] The present invention also proposes a game controller for timely detecting joystick sensing data, characterized in that it includes a game controller body and a joystick system installed on the game controller body; the joystick system is the joystick system for timely detecting joystick sensing data as described in any of the above items.

[0082] To sum up, by adopting the joystick module of the present solution, the joystick system and the game controller receive the potential information of the metal shell of the joystick in real time through the control unit. Since the metal shell is connected to the metal rod with the same potential through the metal sheet, the sensing unit obtains the potential information of the metal rod in real time. The potential information of the metal rod represents the shaking state of the metal rod, thereby achieving the purpose of timely detecting whether the hand shaking the joystick has released the joystick, improving the problem of not being able to detect in real time that the joystick is released in the application scenario of the joystick, obtaining a lower operation delay, and improving the control experience of the game controller to a certain extent.

[0083] It should be noted that those of ordinary skill in the art can appreciate that the modules and algorithm steps of each example described in conjunction with the embodiments disclosed herein can be implemented with electronic hardware, computer software, or a combination of the two. In order to clearly illustrate the interchangeability of hardware and software, the composition and steps of each example have been generally described in terms of function in the above description.
