Description

Technical Field

[0001] The present invention relates to the field of control, and in particular to a 3D joystick and a game controller. Background Art

[0002] A 3D joystick is a device used in TV games and mobile games to control the direction of the handle. Due to differences in production processes, existing joysticks have more or less added a central dead zone in the software processing of the joystick (i.e., the joystick is slightly offset by an angle, and the joystick output value does not change). If the central dead zone is not added, the centering performance of some joysticks is poor, and the handle will also have an output value when there is no operation, resulting in autonomous actions in the game when there is no operation. On the other hand, since the centering performance of the joystick needs to be considered, the force of deflecting the joystick needs to be large, and the force of shaking the joystick cannot be very light. Due to the existence of the central dead zone and the large force of deflecting the joystick, it is difficult for players to use the joystick for precise control, especially for aiming control and other operations in games that require fine control, such as CS. Therefore, it is necessary to propose a 3D joystick that can improve the centering performance of the joystick and improve the fine control ability of the joystick. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a 3D joystick that can improve the centering performance of the joystick and enhance the fine control capability of the joystick.

[0004] The invention also provides a game handle.

[0018] When the control board reads that the sensing component does not collect the touch signal, the current voltage values ​​of the first adjustable potentiometer and the second adjustable potentiometer are collected and saved as the midpoint voltage value, and converted into the joystick control intermediate value and sent to the processing terminal;

[0019] When the control board reads the touch signal collected by the sensing component, the midpoint voltage value is read as a reference, the current voltage values ​​of the first adjustable potentiometer and the second adjustable potentiometer are collected, and the voltage change is converted into a joystick control offset value and sent to the processing terminal;

[0020] Alternatively, when the control board reads the touch movement signal collected by the sensing component, the joystick control offset value is calculated according to the touch movement signal and sent to the processing terminal.

[0021] Furthermore, it also includes a spring and a fixed base, wherein the spring is used to reset the rocker arm, the spring is located in a hollow area formed below the rocker base and the fixed base, and the fixed base is located above the control board.

[0023] Embodiment A of the present invention has at least the following beneficial effects: through the sensing component and the adjustable potentiometer, the midpoint voltage value of the joystick is saved when there is no operation. When there is a touch operation, the joystick control deviation is calculated according to the saved midpoint voltage value, so that the game does not need to set a center dead zone. In addition, there is no need to consider the centering performance of the joystick, and the force of the joystick deviation can be made lighter, so that the player can control the game more accurately.

[0024] In a second aspect, an embodiment of the present invention provides B: a game controller, comprising a 3D joystick as described in any one of the first aspects, wherein the control panel sends a control signal to a processing terminal, and the processing terminal comprises: a game console corresponding to the game controller.

[0030] The beneficial effects of the present invention are:

[0031] The 3D joystick of the present invention comprises: a sensing component, a first adjustable potentiometer, a second adjustable potentiometer, a joystick swing arm, a first linkage shaft, a second linkage shaft, a joystick base and a control board; the sensing component is located at the top of the joystick swing arm, the first linkage shaft and the second linkage shaft are orthogonally arranged at the central groove of the joystick base, the bottom of the joystick swing arm is located at the center of the orthogonal position, and the joystick base is located on the control board; the first adjustable potentiometer is connected to the first linkage shaft, the second adjustable potentiometer is connected to the second linkage shaft, the first linkage shaft and the second linkage shaft convert the swinging motion of the joystick swing arm into a rotational motion, and drive the first adjustable potentiometer and the second adjustable potentiometer to generate voltage changes; the joystick swing arm includes a swing arm through hole inside, the first linkage shaft includes a first through hole inside, the second linkage shaft includes a second through hole, the joystick base includes a base through hole, and the signal line of the sensing component is connected to the control board through a plurality of through holes; the control board obtains the touch sensing signal of the sensing component and the voltage values ​​of the first adjustable potentiometer and the second adjustable potentiometer, and sends a control signal to the processing terminal.

[0032] Through the sensing component and the adjustable potentiometer, it is ensured that the joystick outputs the middle value of the joystick control when there is no operation.

[0037] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Embodiment 1:

[0040] Embodiment 1 of the present invention provides a 3D joystick.

[0041] Figure 1 An exploded view of a 3D joystick provided in an embodiment of the present invention, and a top view of the appearance of corresponding components on the right, such as Figure 1 As shown, the 3D joystick includes from top to bottom:

[0042] Rocker housing 1: used to fix the various components into a whole (not shown in the figure);

[0043] Rocker cap 2: It can be disc-shaped or hemispherical, and can also be made of flexible material, mainly for easy operation and easy grasping during use. Figure 1 It is only for illustration and does not limit its specific shape.

[0044] Sensing component 3: used to generate touch sensing signals according to touch actions. The touch sensing signals in this embodiment include: touch signals and touch movement signals, that is, touch signals refer to: whether there is touch, touch duration, etc.; touch movement signals refer to the movement angle signals of the finger on the joystick cap, back and forth, left and right.

[0045] The rocker arm 4 has a slot 41 at the top for placing the sensing component 3 for obtaining the rocking motion or changing the deflection angle. The rocker arm 4 can be set to a rod shape for easy operation.

[0046] The second linkage shaft 6 is orthogonally arranged with the first linkage shaft 5 at the middle and lower part of the rocker arm 4, and the bottom of the rocker arm 4 is located at the central groove of the rocker base. The rocker arm 4 is orthogonally arranged with the first linkage shaft 5 and the second linkage shaft 6, so that the first linkage shaft 5 can convert the x-axis swing of the rocker arm 4 into the rotational motion of the x-axis, and the second linkage shaft 6 can convert the y-axis swing of the rocker arm 4 into the rotational motion of the y-axis, so that the rocker arm 4 can correspond the 360-degree swing state to different x-axis and y-axis coordinates respectively. That is, the swing of the rocker arm 4 is converted into torque, which is output through the first linkage shaft 5 and the second linkage shaft 6 and drives other accessories to work, such as the first adjustable potentiometer 10 and the second adjustable potentiometer 11 are respectively connected to the first linkage shaft 5 and the second linkage shaft 6, and the resistance value of the access circuit is changed through the rotational motion, thereby changing the voltage value.

[0047] The rocker base 7 is used to support and fix the rocker swing arm 4, the first linkage shaft 5 and the second linkage shaft 6.

[0048] Spring 8: used to reset the rocker so that it automatically returns to the center. In this embodiment, the spring 8 is used as an example to return the rocker to the center, but other devices that can achieve the reset function are simple replacements for the spring 8 and are also within the protection scope of this embodiment.

[0049] Fixed base 9: used to place spring 8 and fix the entire rocker as a whole.

[0050] The control board 12 is used to obtain the touch sensing signal of the sensing component 3 and the voltage values ​​of the first adjustable potentiometer 10 and the second adjustable potentiometer 11, and send a control signal to the processing terminal, which may be a game console.

[0051] Among them, the rocker cap 2 is located at the top of the rocker housing 1 and on the rocker arm 4, the induction component 3 is located in the slot 41 at the top of the rocker arm 4, and the middle of the rocker cap 2 has a rocker cap 21 opening, which matches the shape of the top of the rocker arm 4, that is, the top of the rocker arm 4 can be embedded in the middle of the rocker cap 2. The first linkage shaft 5 and the second linkage shaft 6 are orthogonally arranged at the middle and lower part of the rocker arm 4, and the bottom of the rocker arm 4 is located at the center of the orthogonal position and is interlaced and connected. The first linkage shaft 5 and the second linkage shaft 6 are respectively matched with the rocker arm 4 to be retained in the rocker base 7 and can rotate accordingly. The spring 8 is located in the hollow area formed by the lower part of the rocker base 7 and the fixed base 9, and the fixed base 9 is located on the control board 12.

[0052] The first adjustable potentiometer 10 is connected to the first linkage shaft 5 to detect the rotation state of the first linkage shaft 5. The second adjustable potentiometer 11 is connected to the second linkage shaft 6 to detect the rotation state of the second linkage shaft 6. The first linkage shaft 5 and the second linkage shaft 6 convert the swinging motion of the rocker arm 4 into rotational motion, and correspondingly drive the first adjustable potentiometer 10 and the second adjustable potentiometer 11 to generate voltage changes.

[0053] The rocker arm 4 includes a rocker arm through hole, the first linkage shaft 5 includes a first through hole 51, the second linkage shaft 6 includes a second through hole 61, the rocker base 7 includes a base through hole 71, the spring 8 includes a spring through hole 81 (i.e., the hollow part of the spring, not marked in the figure), and the fixed base 9 includes a fixed base through hole 91. The signal line 31 of the sensing component 3 is connected to the control board 12 through the rocker arm through hole, the first through hole 51, the second through hole 61, the base through hole 71, the spring through hole 81, and the fixed base through hole 91 in sequence, and is used to transmit the touch sensing signal to the control board 12.

[0054] The first adjustable potentiometer 10 and the second adjustable potentiometer 11 can be optionally adjustable resistors. The resistance value is changed by adjusting the length of the resistance wire connected to the circuit according to the rotational movement, that is, the voltage value of the adjustable resistor is changed. The first adjustable potentiometer 10 senses the X-axis angle signal of the 3D joystick according to the voltage change, and the second adjustable potentiometer 11 senses the Y-axis angle signal of the 3D joystick according to the voltage change.

[0055] like Figure 2 As shown, it is a top view of the first linkage shaft and the second linkage shaft components in this embodiment. It can be seen from the figure that the first linkage shaft 5 and the second linkage shaft 6 are arranged orthogonally, the rocker arm 4 is located at the center of the orthogonal position and is interlaced and connected, the first adjustable potentiometer 10 is connected to the first linkage shaft 5, and the second adjustable potentiometer 11 is connected to the second linkage shaft 6.

[0056] The working principle of the 3D joystick of this embodiment is described in detail below.

[0057] In this embodiment, the sensing component 3 includes: a touch button or a photoelectric sensing component 33.

[0058] The first case: when the sensing component 3 uses a touch button, the touch button can sense whether the user is touching the button, and the touch button generates a touch signal. For example, when the sensing component 3 is located at the top of the joystick arm 4, and the top of the joystick arm 4 is embedded in the joystick cap 2, it senses whether the user places his hand on the joystick cap 2, and the control board 12 reads the current touch state of the sensing component 3 through the signal line 31.

[0059] If the sensing component 3 does not collect a touch signal (i.e., the user's hand is not detected on the joystick cap 2), the control board 12 collects the current voltage values ​​of the first adjustable potentiometer 10 and the second adjustable potentiometer 11 as midpoint voltage values ​​and saves them, i.e., the X-axis midpoint voltage value corresponding to the first adjustable potentiometer 10 and the Y-axis midpoint voltage value corresponding to the second adjustable potentiometer 11, and converts the voltage value into a joystick control intermediate value according to the corresponding relationship between voltage and displacement and sends it to the processing terminal via wired or wireless transmission.

[0060] If the sensing component 3 collects a touch signal (i.e., detects that the user's hand is placed on the joystick cap 2), and the user shakes the joystick swing arm 4 to cause it to produce reciprocating motion in different directions, the reciprocating motion is converted into rotational motion through the first linkage shaft 5 and the second linkage shaft 6, driving the voltage of the first adjustable potentiometer 10 and the second adjustable potentiometer 11 to change, and the control board 12 uses the midpoint voltage value saved when not touched as a reference, collects the current voltage of the first adjustable potentiometer 10 and the second adjustable potentiometer 11, and obtains the joystick control offset value based on the voltage change difference between the voltage value and the midpoint voltage value, and sends the offset value to the processing terminal via wired transmission or wireless transmission.

[0061] The second situation: when the sensing component 3 adopts the photoelectric sensing component 33, the photoelectric sensing component can generate a touch signal and a touch movement signal.

[0062] like Figure 3 As shown, it is a schematic diagram of the structure of the photoelectric sensing component. The surface of the photoelectric sensing component 33 has a glass panel 331, and the interior is a photoelectric collection component 332, which can sense whether the user's finger touches the joystick cap and the movement information of the finger on the joystick cap, and generate a touch sensing signal including a touch signal and a touch movement signal. The control board 12 reads the current touch sensing signal of the sensing component 3 through the signal line 31.

[0063] If the control board 12 reads that the sensing component 3 has not collected any touch signal (i.e., the user's hand is not detected on the joystick cap 2), the control board 12 collects and saves the current voltage values ​​of the first adjustable potentiometer 10 and the second adjustable potentiometer 11 as midpoint voltage values, i.e., the X-axis midpoint voltage value corresponding to the first adjustable potentiometer 10 and the Y-axis midpoint voltage value corresponding to the second adjustable potentiometer 11, and converts the voltage value into a joystick control intermediate value according to the corresponding relationship between voltage and displacement, and sends it to the processing terminal via wired or wireless transmission.

[0064] When the control board 12 reads that the sensing component 3 collects the touch signal but does not collect the touch movement signal, that is, the current photoelectric sensing component 33 detects that the user places the hand on the joystick cap 2, and the user shakes the joystick swing arm 4 to make it produce reciprocating motion in different directions. The reciprocating motion is converted into rotational motion through the first linkage shaft 5 and the second linkage shaft 6, which drives the voltage of the first adjustable potentiometer 10 and the second adjustable potentiometer 11 to change. The control board 12 uses the midpoint voltage value saved when not touched as a reference, collects the current voltage of the first adjustable potentiometer 10 and the second adjustable potentiometer 11, and obtains the joystick control offset value based on the voltage change difference between the voltage value and the midpoint voltage value, and sends the offset value to the processing terminal via wired transmission or wireless transmission.

[0065] Or when the control board 12 reads that the sensing component 3 collects the touch movement signal, that is, the current photoelectric sensing component 33 detects that the user places his hand on the joystick cap 2, and at the same time detects that the user only makes a slight touch movement on the photoelectric sensing component 33 without shaking the joystick, then the joystick control offset value is directly calculated based on the collected touch movement signals in different movement directions and sent to the processing terminal.

[0066] It can be understood that the correspondence between the voltage and displacement of the existing joystick can be used in the present embodiment, and the correspondence can be obtained by multiple debugging and fitting, which is not specifically limited here. In addition, if wireless transmission is adopted, corresponding wireless transmission components need to be equipped, such as WIFI transmitters and receivers, etc., which are not specifically limited here.

[0067] In this embodiment, when the user is not detected touching the joystick cap 2 with his hand, the joystick control intermediate value and the joystick control offset value sent by the control board 12 are both joystick output values. There is no need to consider the joystick centering error or set a center dead zone, because a slight shake of the joystick cap 2 or movement on the photoelectric sensing component 33 can output the corresponding joystick control offset value, thereby ensuring precise control of the game and improving the user experience.

[0068] When the photoelectric sensing component 33 is used, the slight movement information of the finger (without shaking the joystick) can be converted into the joystick control offset, and some subtle movements in the game can be accurately controlled, especially the aiming operation in CS games. Such a joystick structure and processing algorithm take into account the advantages of both fast movement of the joystick and precise positioning of the mouse, thereby improving the user experience.

[0069] In a specific implementation scenario, the processing terminal is a game console, and the control board 12 can be a processing board including a single-chip microcomputer. The single-chip microcomputer, for example, uses a chip from Taiwan, China, model WT6573F, and is connected according to the circuit manual of the chip to form a processing board. The chip has a USB port, which can communicate with the game console via USB, and can also achieve wireless connection with the game console by adding a WIFI transmitter and receiver. At the same time, the single-chip microcomputer has a 12BIT ADC (analog-to-digital conversion device), which can convert the voltage values ​​of the first adjustable potentiometer 10 and the second adjustable potentiometer 11 into digital quantities, which is convenient for the single-chip microcomputer to process, and has an I2C bus, which can communicate with the signal line 31 of the sensing component 3, so as to facilitate reading the touch sensing signal collected by the sensing component 3.

[0070] like Figure 4 As shown, it is a cross-sectional structure diagram of the present embodiment. It can be seen from the figure that the 3D joystick at least includes: a sensing component 3, a signal line 31, a joystick cap 2, a joystick arm 4, a joystick base 7, and a fixed base 9. It can be seen from the figure that the joystick arm 4 is embedded in the joystick cap 2, the sensing component 3 is embedded in the joystick arm 4, and the signal line 31 passes through multiple through holes and passes out from the fixed base 9 to transmit the signal.

[0071] Embodiment 2:

[0072] This embodiment provides a game controller, including the 3D joystick as described in any one of the first embodiments, and sends a control signal to a processing terminal through a control panel. The processing terminal includes: a game console corresponding to the game controller.

[0073] By adopting the game handle, the user experience can be improved.

[0074] Embodiment three:

[0075] This embodiment provides a joystick control method, which is applied to a 3D joystick as in any one of the first embodiments, and includes:

[0076] S1: Acquire the touch sensing signal sensed by the sensing component;

[0077] S2: Obtaining voltage values ​​corresponding to voltage changes generated by the first adjustable potentiometer and the second adjustable potentiometer according to the swing state of the rocker arm;

[0078] S3: The control board sends a control signal to the processing terminal according to the touch sensing signal and the voltage values ​​of the first adjustable potentiometer and the second adjustable potentiometer.

[0079] The specific implementation process of the control method is described in the first embodiment.

[0080] The present invention uses a sensing component and an adjustable potentiometer to ensure that the joystick outputs the middle value of the joystick control when there is no operation. When there is a touch operation, the joystick control deviation is calculated and output based on the saved midpoint voltage value, so that the game does not need to set a center dead zone, so that the player can control the game more accurately. At the same time, since the centering performance is independent of the structure, the joystick can achieve a better feel and improve the player's control experience. Furthermore, in terms of production, since there is no requirement for neutralization of the structural parts, the process requirements do not need to be very high, which will also reduce the production cost of the joystick.

[0081] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
