The PCB board sends the capacitance data to the main circuit board, thereby detecting the rocker's movement.

[0004] As is well known, capacitance is directly related to dielectric constant. In actual use, when environmental factors such as temperature and humidity change, the dielectric constant will also change, affecting the measurement of capacitance and thus affecting the accuracy of joystick action detection.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] refer to Figure 1 This application discloses a joystick assembly 10 for a game controller. The joystick assembly 10 can be installed on the shell of the game controller (not shown). During use, the operator can control virtual objects through the joystick assembly 10.

[0036] Combination Figure 2 and Figure 3 The rocker assembly 10 includes a mounting base 100, a rocker arm 200, and a first capacitance detection assembly 300. The rocker arm 200 is movably mounted on the mounting base 100. The mounting base 100 is a nearly hollow rectangular box shape, used to provide support and limiting protection for other components. The rocker arm 200 is nearly cylindrical and passes through the mounting base 100. The mounting base 100 can be assembled from two or more parts to facilitate the assembly and positioning of the rocker arm 200 and its associated components on the mounting base 100. (See also...) Figure 4 , Figure 5 and Figure 6 The first capacitance detection assembly 300 includes a dielectric plate 310, a first detection electrode 320, a second detection electrode 330, and a compensation electrode 340. The first detection electrode 320, the second detection electrode 330, and the compensation electrode 340 are respectively fixed relative to the mounting base 100. This relative fixing can be achieved through a direct fixed connection or through an intermediate structure. For example, the first detection electrode 320 can be directly fixed to the mounting base 100 or fixedly connected to the mounting base 100 through other structures.

[0037] For example, the rocker assembly 10 may include a first housing 400 that engages and is fixed to the mounting base 100. The first housing 400 and the mounting base 100 enclose a mounting cavity 401, in which a dielectric plate 310, a first detection electrode 320, a second detection electrode 330, and a compensation electrode 340 are housed. Specifically, refer to Figure 7The first housing 400 may have an integrally formed base 410 and a locking arm 420 protruding from one side of the base 410. The base 410 has a recessed receiving groove 402 on the side facing the mounting base 100. The locking arm 420 is provided at two edges in the width direction of the base 410, and the locking arm 420 protrudes outward from the base 410 towards the side where the rocker arm 200 is located. The mounting base 100 has two spaced locking holes 101 on the side where the first capacitor detection assembly 300 is located (see reference). Figure 2 The two locking holes 101 engage with the two locking arms 420 in a one-to-one manner, thereby enabling the assembly and fixation of the first cover 400 and the mounting base 100, and improving the assembly efficiency of the first cover 400 and the mounting base 100. The first detection electrode 320, the second detection electrode 330 and the compensation electrode 340 can be confined within the first cover 400, thereby achieving relative fixation with respect to the mounting base 100.

[0038] Continue to refer to Figure 6 A first detection plate 320 and a second detection plate 330 are spaced apart to form a detection capacitor C1. A dielectric plate 310 is disposed between the first detection plate 320 and the second detection plate 330, and the dielectric plate 310 is linked with the rocker arm 200 to be driven to move relative to the detection capacitor C1. A compensation plate 340 is spaced apart from the first detection plate 320 to form a compensation capacitor C2. When the user pushes the rocker arm 200 to swing relative to the mounting base 100, the rocker arm 200 drives the dielectric plate 310 to move relative to the detection capacitor C1. The area of ​​the dielectric plate 310 between the first detection plate 320 and the second detection plate 330 of the detection capacitor C1 changes, thereby causing a change in the capacitance value of the detection capacitor C1. A mapping relationship can be established between the capacitance value of the detection capacitor C1 and the position of the dielectric plate 310 in the detection capacitor C1. Therefore, the motion parameters of the rocker arm 200 can be determined by using the change in the capacitance value of the detection capacitor C1, that is, the motion detection of the rocker arm 200 can be realized.

[0039] Further, refer to Figure 8 and Figure 9The first detection electrode 320 and the second detection electrode 330 can be unfolded on paper for easy description. The second detection electrode 330 includes a first electrode 331 and a second electrode 333 spaced apart, located on the same side of the dielectric plate 310. The first electrode 331 and the second electrode 333 can be sheet-like and have relatively flat surfaces on opposite sides in the thickness direction. The second detection electrode 330 can also be sheet-like and have relatively flat surfaces on opposite sides in the thickness direction. The first electrode 331 and the first detection electrode 320 form a first capacitor C11, and the second electrode 333 and the first detection electrode 320 form a second capacitor C13. Considering engineering errors, the same side of the first electrode 331 and the second electrode 333 can be regarded as being located on the same geometric plane. The surface of the first detection electrode 320 facing the first electrode 331 can be set basically parallel to the first electrode 331 and the second electrode 333, so that the electrode spacing of the first electrode 331 and the first detection electrode 320 is basically equal to the electrode spacing of the second electrode 333 and the first detection electrode 320, so that the first capacitor C11 and the second capacitor C13 have a near-ideal capacitor structure, simplifying the measurement of capacitance value.

[0040] The rocker arm 200 can cause the dielectric plate 310 to swing relative to the first capacitor C11 and the second capacitor C13. During the movement of the dielectric plate 310 relative to the first capacitor C11 and the second capacitor C13, the capacitance of one of the capacitors increases while the capacitance of the other decreases. This change in capacitance value can determine the swing direction of the rocker arm 200. Combining the mapping relationship between capacitance value and the position of the rocker arm 200, motion parameters such as the swing angle of the rocker arm 200 can be determined, thereby achieving motion detection of the rocker arm 200. Furthermore, the first electrode plate 331 and the second electrode plate 333 can have the same shape and structure, for example, both being fan-shaped. During the movement of the dielectric plate 310 relative to the first capacitor C11 and the second capacitor C13, considering measurement errors, this structure can ensure that the absolute value of the increase in the capacitance value of the first capacitor C11 is basically equal to the absolute value of the decrease in the capacitance value of the second capacitor C13. This simplifies the mapping relationship between the capacitance value of the detection capacitor C1 and the motion parameters of the rocker arm 200, and makes it easier to determine the swing angle, direction and other motion parameters of the rocker arm 200.

[0041] It is understandable that the dielectric plate 310 can be made of materials with relatively good insulation properties under normal conditions, such as ceramics or plastics, while the first electrode plate 331, the second electrode plate 333, the first detection electrode plate 320, and the compensation electrode plate 340 can be made of materials with relatively good conductivity under normal conditions, such as copper. It is also understandable that the above-mentioned limitations on the structure and position of the first electrode plate 331, the second electrode plate 333, and the first detection electrode plate 320 should not be interpreted as strict limitations; that is, the ideal capacitor structure described above is not mandatory and can be adjusted according to actual production needs to meet the requirements of mass industrial production.

[0042] Combination Figure 8 and Figure 9 The compensation plate 340 and the first detection plate 320 can have similar shapes and structures, for example, they can be fan-shaped thin sheets. The compensation plate 340 is used to form a compensation capacitor C2 with the first detection plate 320, such as... Figure 6 As shown, the effect of environmental factors such as temperature and humidity on the capacitance value of compensation capacitor C2 is detected. For example, the change in the capacitance value of compensation capacitor C2 can be used to determine the change in dielectric constant, which can then be used to compensate for the detected value of detection capacitor C1, thus ensuring the accuracy of the detection.

[0043] In some embodiments, during the movement of the dielectric plate 310 relative to the first capacitor C11 and the second capacitor C13, the difference in capacitance between the first capacitor C11 and the second capacitor C13 can determine the swing direction of the rocker arm 200. The compensation amount of the compensation capacitor C2 can be set to the difference between its initial capacitance value and its current capacitance value. The initial capacitance value of the compensation capacitor C2 is calibrated at the factory when the rocker arm assembly 10 is manufactured, and the current capacitance value of the compensation capacitor C2 reflects the capacitance value after changes in environmental factors such as air temperature and humidity during actual use. When environmental factors such as air temperature and humidity have not changed compared to the factory settings, this compensation amount is 0; when environmental factors such as air temperature and humidity have changed compared to the factory settings, this compensation amount can be reflected. After using this compensation amount to compensate for the difference in capacitance values ​​between the first capacitor C11 and the second capacitor C13, it can be ensured that the mapping relationship between the first capacitor C11, the second capacitor C13 and the swing angle of the dielectric plate 310 is consistent with the factory-calibrated mapping relationship, thereby ensuring the accuracy of the angle detection of the rocker arm 200. Compared with existing technologies, this application adds a separate compensation channel, which can better eliminate the influence of environmental factors such as temperature and humidity on the test results and ensure the accuracy of the test.

[0044] Of course, the compensation of the first capacitor C11 and the second capacitor C13 by the compensation capacitor C2 is not limited to the above method. Other calculation methods can also be used to ensure the detection accuracy of the joystick 200.

[0045] Continue to refer to Figure 3The rocker assembly 10 may include a first rocker arm 510 and a second rocker arm 520 disposed on the mounting base 100. The second rocker arm 520 is arranged crosswise with the first rocker arm 510. The rocker arm 200 passes through the first rocker arm 510 and the second rocker arm 520 and extends out of the mounting base 100. The user can drive the first rocker arm 510 to swing around a first direction and drive the second rocker arm 520 to swing around a second direction via the rocker arm 200. The first direction is perpendicular to the second direction, and the swing of the first rocker arm 510 relative to the mounting base 100 and the swing of the second rocker arm 520 relative to the mounting base 100 can be relatively independent. That is, when the rocker arm 200 drives the first rocker arm 510 to swing relative to the mounting base 100, the position of the second rocker arm 520 relative to the mounting base 100 can remain unchanged; when the rocker arm 200 drives the second rocker arm 520 to swing relative to the mounting base 100, the position of the first rocker arm 510 relative to the mounting base 100 can remain unchanged.

[0046] The second detection electrode 330, dielectric plate 310, first detection electrode 320, and compensation electrode 340 are arranged sequentially along the axial direction (i.e., the first direction) of the first rocker arm 510, with the second detection electrode 330 being further away from the rocker arm 200 than the first detection electrode 320. In other words, the second detection electrode 330 is located further outward from the mounting base 100 than the first detection electrode 320. The dielectric plate 310 is fixedly connected to the first rocker arm 510. When the rocker arm 200 drives the first rocker arm 510 to swing relative to the mounting base 100, it drives the dielectric plate 310 to move between the first detection electrode 320 and the second detection electrode 330, or in other words, it drives the dielectric plate 310 to move between the first electrode 331 and the first detection electrode 320, and between the second electrode 333 and the first detection electrode 320. That is, it swings relative to the first capacitor C11 and the second capacitor C13, thereby causing changes in the capacitance value of the first capacitor C11 and the capacitance value of the second capacitor C13. Combined with the compensation effect of the compensation capacitor C2, the swing direction and swing angle of the first rocker arm 510 can be determined, and the detection accuracy can be guaranteed.

[0047] See again Figure 2 and Figure 3 The rocker assembly 10 may further include a second capacitance detection assembly 600 disposed on the mounting base 100. The structure and working principle of the second capacitance detection assembly 600 may be the same as those of the first capacitance detection assembly 300, and the second rocker arm 520 passes through the second capacitance detection assembly 600. During the process of the rocker arm 200 driving the second rocker arm 520 to swing relative to the mounting base 100, the second capacitance detection assembly 600 can detect the swing direction and swing angle of the second rocker arm 520 and ensure the accuracy of the detection, which will not be elaborated here.

[0048] refer to Figure 8 , Figure 9 and combined Figure 6The first capacitance detection assembly 300 may include a flexible circuit board 350 fixed relative to the mounting base 100. The flexible circuit board 350 includes an integrally formed first part 351, a second part 353, and a bent part 355. The bent part 355 is connected between the first part 351 and the second part 353 and spans across the dielectric plate 310. A first detection electrode 320 and a compensation electrode 340 are integrated into the first part 351, and a second detection electrode 330 is integrated into the second part 353. The internal wiring of the flexible circuit board 350 extends from the first part 351 along the bent part 355 to the second part 353. The flexible circuit board 350 generally includes internal wiring and an external flexible insulating material. This implementation avoids using two separate printed circuit boards to arrange the detection circuit of the first detection capacitor C1, and realizes the integration of the first detection plate 320, the compensation plate 340 and the second detection plate 330 with the flexible circuit board 350. The bending part 355 can smoothly realize the electrical connection between the first part 351 and the second part 353 and ensure the reliability of the electrical connection, which can improve the convenience of assembly.

[0049] Furthermore, combined with Figure 2 The flexible circuit board 350 can be bent and extended to the second capacitance detection assembly 600 and electrically connected to the second capacitance detection assembly 600, thereby simplifying the structure of the circuit components of the rocker assembly 10. For example, the first portion 351 of the flexible circuit board 350 extends and bends approximately 90 degrees to bypass the corner of the mounting base 100 and extend to the second capacitance detection assembly 600. In other embodiments, the second portion 353 of the flexible circuit board 350 extends and bends approximately 90 degrees to bypass the corner of the mounting base 100 and extend to the second capacitance detection assembly 600.

[0050] In this embodiment, the first detection electrode 320, the compensation electrode 340, and the second detection electrode 330 (first electrode 331 and second electrode 333) can be encapsulated by the flexible insulating material of the flexible circuit board 350 and electrically connected to the internal circuitry of the flexible circuit board 350 to form the necessary capacitance detection circuit, thereby realizing the design of integrating the first detection electrode 320 and the compensation electrode 340 into the first part 351 and the second detection electrode 330 into the second part 353.

[0051] Of course, it is necessary to ensure insulation between the first detection electrode 320, the compensation electrode 340, and the second detection electrode 330 using flexible insulating materials. This integrated packaging structure can also ensure the reliability of the electrical connection between the first detection electrode 320, the compensation electrode 340, the second detection electrode 330, and the internal circuitry of the flexible circuit board 350. In related technologies, there is a method of bonding a metal sheet to a printed circuit board to form a detection capacitor. This solution is difficult to guarantee the reliability of the electrical connection between the metal sheet and the capacitor detection circuit, resulting in a low product yield. However, with the implementation method of this application, due to the integrated design of the first detection electrode 320, the compensation electrode 340, the second detection electrode 330, and the flexible circuit board 350, the electrical connection between the internal circuitry of the flexible circuit board 350 and the first detection electrode 320, the compensation electrode 340, and the second detection electrode 330 has higher reliability, which can improve the yield of the rocker assembly 10.

[0052] In other embodiments, the first detection electrode 320 and the compensation electrode 340 can be integrated into the second part 353, and the second detection electrode 330 can be integrated into the first part 351. The bending part 355 can be omitted, and the internal circuitry of the first part 351 and the second part 353 can be electrically connected through other structures and then connected to an external circuit board, such as the motherboard of a game controller.

[0053] Further reference Figure 6 The flexible circuit board 350 includes a first reinforcing plate 357 and a second reinforcing plate 359. The first reinforcing plate 357 is approximately the same size as the first part 351 and is fixedly connected. The second reinforcing plate 359 is approximately the same size as the second part 353 and is fixedly connected. A first rocker arm 510 passes through the first reinforcing plate 357, the first part 351, the dielectric plate 310, the second part 353, and the second reinforcing plate 359, such that the first part 351, the dielectric plate 310, and the second part 353 are sequentially distributed along the axial direction of the first rocker arm 510.

[0054] The first reinforcing plate 357 can be made of rigid plastic, such as a plastic sheet with a Shore hardness of 70D or higher. After being fixed to the first part 351 of the flexible circuit board 350, it can improve the overall structural rigidity and prevent the first part 351 from easily deforming during assembly and use. The second reinforcing plate 359 can also be made of rigid plastic, such as a plastic sheet with a Shore hardness of 70D or higher. After being fixed to the second part 353 of the flexible circuit board 350, it can similarly improve the overall structural rigidity and prevent the second part 353 from easily deforming during assembly and use.

[0055] Specifically, refer to Figure 2 and combined Figure 7 , Figure 8The first part 351 has a first limiting through hole 3511, which penetrates the first reinforcing plate 357. The second part 353 has a second limiting through hole 3531, which penetrates the second reinforcing plate 359. The first cover 400 includes a first limiting post 430 and a second limiting post 440 integrally formed with the base 410. The first limiting post 430 passes through the first limiting through hole 3511 to fix the first part 351, and the second limiting post 440 passes through the second limiting through hole 3531 to fix the second part 353.

[0056] In the embodiment where the base 410 is recessed on the side facing the mounting base 100 to form a receiving groove 402, the first limiting post 430 and the second limiting post 440 are located on the same side of the base 410 as the engaging arm 420, and the first limiting post 430 protrudes more from the base 410 than the second limiting post 440. In other words, in the axial direction of the first rocker arm 510, the end of the first limiting post 430 protrudes from the end of the second limiting post 440 on the side facing the mounting base 100. Thus, the first limiting post 430 passes through to the first part 351 closer to the rocker arm 200, and the second limiting post 440 passes through to the second part 353, thereby fixing the first part 351, the second part 353 and the first cover 400, and thus ensuring the relative position between the first detection electrode plate 320, the second detection electrode plate 330 and the compensation electrode plate 340.

[0057] The first cover 400 may further include a third limiting post 450 integrally formed with the base 410. The third limiting post 450, the first limiting post 430, the second limiting post 440, and the locking arm 420 are located on the same side of the base 410. The mounting base 100 has a third limiting through hole 103, and the third limiting post 450 passes through the third limiting through hole 103 to realize the positioning of the first cover 400 in the mounting base 100, thereby ensuring the relative position of the dielectric plate 310 with the first detection electrode plate 320 and the second detection electrode plate 330.

[0058] Three first limiting posts 430 can be spaced apart, with the center line connecting the three first limiting posts 430 forming a triangle. Similarly, three second limiting posts 440 can be spaced apart, with the center line connecting the three second limiting posts 440 forming a triangle. The number of first limiting through holes 3511 is equal to and corresponds one-to-one with the number of first limiting posts 430, and the number of second limiting through holes 3531 is equal to and corresponds one-to-one with the number of second limiting posts 440. The cooperation between the first limiting posts 430 and the first limiting through holes 3511, and the cooperation between the second limiting posts 440 and the second limiting through holes 3531, further ensures the relative positional accuracy of the first detection plate 320 and the second detection plate 330, thereby ensuring the detection accuracy of the detection capacitor C1.

[0059] Three third limiting posts 450 can be set at intervals, and the center line of the three third limiting posts 450 forms a triangle. The number of third limiting through holes 103 is equal to the number of third limiting posts 450 and corresponds one-to-one. The cooperation between the third limiting posts 450 and the third limiting through holes 103 can further ensure the relative positional accuracy of the first detection electrode 320, the second detection electrode 330 and the dielectric plate 310, thereby ensuring the detection accuracy of the detection capacitor C1.

[0060] Furthermore, combined with Figure 6 and Figure 7 A clearance notch 403 can be provided at the position corresponding to the bent portion 355 in the first cover 400, and the bent portion 355 is received in the clearance notch 403. Compared with increasing the volume of the receiving groove 402 in the first cover 400 to accommodate the bent portion 355, this structure of the present embodiment can reduce the size of the first cover 400 in the axial direction of the first rocker arm 510 and in the axial direction of the rocker arm 200, thereby reducing the size of the entire rocker arm assembly 10 in the axial direction of the first rocker arm 510 and in the axial direction of the rocker arm 200, and improving the structural compactness of the entire rocker arm assembly 10. Of course, the clearance notch 403 can also prevent the first cover 400 from excessively compressing the bent portion 355, which could lead to poor contact of the internal circuitry of the flexible circuit board 350.

[0061] In some embodiments, the first housing 400 may have an adjustment hole 405 on the axial direction of the first rocker arm 510. The adjustment hole 405 extends through opposite sides of the first rocker arm 510, meaning the first rocker arm 510 can be observed from the outside of the first housing 400. One end of the first rocker arm 510 that passes through the flexible circuit board 350 protrudes from the side of the second part 353 opposite to the first part 351. During the assembly or maintenance of the rocker arm assembly 10, tools such as tweezers can be inserted through the adjustment hole 405 to adjust the position of the first rocker arm 510, for example, to achieve centering and resetting of the first rocker arm 510.

[0062] The second capacitance detection component 600 can also be assembled and positioned with the second rocker arm 520 and the mounting base 100 using a similar structure to improve assembly efficiency and ensure positioning accuracy. For example, the rocker arm assembly 10 may include a second housing 800 with the same structure as the first housing 400 to ensure the positioning accuracy of the detection capacitor C1 and compensation capacitor C2 in the second capacitance detection component 600 relative to the mounting base 100, which will not be elaborated here.

[0063] The rocker assembly 10 includes a mounting base 100, a rocker arm 200, and a first capacitor detection assembly 300. The rocker arm 200 is movably mounted on the mounting base 100. The first capacitor detection assembly 300 includes a dielectric plate 310, a first detection electrode 320, a second detection electrode 330, and a compensation electrode 340. The first detection electrode 320, the second detection electrode 330, and the compensation electrode 340 are respectively fixed relative to the mounting base 100. The first detection electrode 320 and the second detection electrode 330 are spaced apart to form a detection capacitor C1. The dielectric plate 310 is located between the first detection electrode 320 and the second detection electrode 330, and the dielectric plate 310 is linked with the rocker arm 200 to be driven to move relative to the detection capacitor C1. The compensation electrode 340 is spaced apart from the first detection electrode 320 to form a compensation capacitor C2. The relative movement between the dielectric plate 310 and the detection capacitor C1 can cause a change in the capacitance value of the detection capacitor C1, thereby enabling the detection of the movement of the joystick 200. The compensation capacitor C2 can be used to detect the influence of environmental factors such as temperature and humidity on the capacitance value, thereby compensating for the detection of the detection capacitor C1 and ensuring the accuracy of the movement detection of the joystick 200.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
