[0053] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0054] It should be noted that when a component is referred to as being "fixed on" or "disposed on" or "installed on" another component, it may be directly or indirectly located on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The orientation or position indicated by the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. is based on the orientation or position shown in the accompanying drawings and is only for the convenience of description and cannot be understood as a limitation on the present technical solution. The terms "first", "second", "third", and "fourth" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0055] See also Figure 1 , Figure 2 The present embodiment provides a capacitive joystick, including a housing 1, a bottom plate 2, a control rod 3 and a universal joint 4. The bottom plate 2 is fixed to the bottom of the housing 1. The top of the housing 1 is provided with a first opening 101 for the lower end of the control rod 3 to pass through. The control rod 3 is installed in the first opening 101 through the universal joint 4. A conductive glue 5 is provided at the bottom of the control rod 3. A capacitor plate 6 is provided at the top of the bottom plate 2. The conductive glue 5 faces the capacitor plate 6. There is a gap between the conductive glue 5 and the capacitor plate 6. The gap is extremely small (within 1 mm). A PCB board 7 is provided at the bottom of the bottom plate 2. The PCB board 7 is electrically connected to the capacitor plate 6. When the user moves the control rod 3 with a finger, the static electricity on the finger is transferred to the conductive glue 5 through the control rod 3. The moving of the control rod 3 causes the inductive capacitance value between the conductive glue 5 and the conductive layer of the capacitor plate 6 to change. After the inductive capacitance value detected by the capacitive touch IC on the PCB board 7 changes, a confirmation signal of a key press is output, thereby realizing the control function of the joystick.

[0056] The capacitive joystick provided by the present invention utilizes the principle of capacitive sensors to replace the function of the 3D head in an ordinary joystick, thereby realizing a non-contact joystick. The capacitor plate 6 and the conductive adhesive 5 are of an inductive type and do not generate relative friction. Therefore, the capacitor plate 6 will not be worn out, and the service life is long. At the same time, the structure is simple, the operation is convenient, the precision is high, the cost is low, and the user experience is high.

[0057] The working principle of the non-contact rocker is: there is an electric field between any two conductive objects. When a piece of material that has a considerable influence on the electric field is brought into the electric field of the capacitor formed at the intersection of the two conductive objects, it affects the capacitance of the capacitor, and this change can be detected by measurement.

[0058] Two arrays, X and Y, are created on the capacitor plate. When the user moves the joystick 3, the gap between the conductive glue 5 and the capacitor plate 6 is within 1mm, generating an inductive capacitor. At this time, it will locate the coordinates of the position according to the strongest inductive capacitance on the X and Y axes, and input the two coordinates of the X and Y axes to lock the position. That is, when the user moves 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.

[0059] 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 material that affects the electric field is close, the capacitance changes. This change can be detected and measured, so that the position of the finger (other material that affects the electric field) can be detected.

[0060] In one embodiment, there may be no gap between the conductive glue 5 and the capacitor plate 6, and the two are in direct contact. When the user moves the control rod 3 with a finger, the conductive glue 5 on the control rod 3 contacts the capacitor plate 6, and the capacitive touch IC on the PCB board 7 detects the corresponding change value and outputs a confirmation signal of the button being pressed, thereby realizing the control function of the joystick. The present invention can be made into a contact joystick according to customer needs, so as to meet different market needs.

[0061] The working principle of the contact joystick is as follows: two arrays, X and Y, are created on the capacitor plate. When the user moves the joystick 3 and the conductive glue 5 touches a point on the capacitor plate 6, it locates the coordinates of the position and inputs the X and Y axis coordinates to lock the position. That is, when the user moves 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.

The upper end of the control rod body 301 is fixedly connected to the lower end of the control rod tube 302, and the upper end of the control rod tube 302 is detachably connected to the control rod cap 303.

[0063] See also Figure 5 , Figure 6 The universal joint 4 is provided with two first rotating shafts 401 and two first rotating shaft seats 402 which are arranged opposite to each other. The two first rotating shafts 401 and the two first rotating shaft seats 402 are distributed in a cross shape. Two second rotating shaft seats 102 which are arranged opposite to each other are arranged outside the first opening 101. The second rotating shaft seats 102 are matched with the first rotating shaft 401. The universal joint 4 is installed on the second rotating shaft seat 102 through the first rotating shaft 401. Two second rotating shafts 3021 which are arranged opposite to each other are arranged on the control rod tube 302. The second rotating shaft 3021 is matched with the first rotating shaft seat 402. The control rod tube 302 is installed on the first rotating shaft seat 402 through the second rotating shaft 3021. The universal joint 4, also known as a universal joint, is a component for realizing variable angle power transmission. The present invention realizes 360-degree control of the rocker by cooperating with the control rod 3 and the face shell 1 through the universal joint 4. It is not only simple in structure, but also flexible in operation and low in cost.

[0064] See also Figures 4 to 6 The first rotating shaft 401 is provided with a first cut corner 4011 at the outer lower end, the first rotating shaft seat 402 is provided with a second cut corner 4021 at the inner upper end, the second rotating shaft 3021 is provided with a third cut corner 30211 at the outer lower end, and the second rotating shaft seat 102 is provided with a fourth cut corner 1021 at the inner upper end. When the universal joint 4 is installed on the second rotating shaft seat 102 installed on the surface shell 1 through the first rotating shaft 401, the universal joint 4 can be easily installed on the second rotating shaft seat 102 of the surface shell 1 through the first cutting angle 4011 on the first rotating shaft 401 and the fourth cutting angle 1021 on the first rotating shaft seat 402; when the control rod tube 302 is installed on the first rotating shaft seat 402 of the universal joint 4, the control rod tube 302 can be easily installed on the first rotating shaft seat 402 of the universal joint 4 through the third cutting angle 30211 on the second rotating shaft 3021 and the second cutting angle 4021 on the first rotating shaft seat 402.

The limited spring ring 8 is used to limit the toggle range of the control console 304, thereby limiting the gap between the conductive glue 5 and the capacitor plate 6. If there is no limited spring ring 8, when the control rod 3 is toggled, the gap between the conductive glue 5 at the bottom of the toggle control rod 3 and the capacitor plate 6 will be greater than 1 mm, resulting in the inability to generate capacitive induction. When the control rod 3 is moved, the console 304 squeezes the limit spring ring 8, and the limit spring ring 8 exerts a reaction force on the console 304, thereby limiting the range of motion of the console 304 and ensuring the accuracy of the control rod 3. If there is no limit base 9 and limit spring ring 8, the range of the console 304 is too large, and the conductive glue 5 is likely to deviate from the capacitor plate 6.
