[0030] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] like Figure 1 As shown, the photoelectric control device 10 includes a bottom cover 11 and a shell 12 covered on the bottom cover, a rotating shaft 13, a repositionable rocker 14 and a photoelectric sensor 15. The shell 12 is clamped on the top of the bottom cover 11 and forms a storage compartment for the rocker 14 between the shell 12 and the bottom cover 11, and has a bottom opening in the middle of the bottom cover 11; the two ends of the rotating shaft 13 are passed through the shell 12, and the rotating shaft 13 is located in the storage compartment; the rocker 14 is passed through the rotating shaft 13, and the bottom end of the rocker 14 is movably located on the bottom opening 111 of the bottom cover 11, and the rotating shaft 13 provides a supportable fulcrum for the rocker 14 to swing, and the rocker 14 can rotate 360° with the rotating shaft 13 as the fulcrum; the photoelectric sensor 15 is arranged below the bottom cover 11, and detects the motion trajectory of the bottom end of the rocker 14 through the bottom opening 111. The photoelectric control device detects the motion trajectory of the bottom end of the joystick through the photoelectric sensor 15 at the bottom without being disturbed by the magnetic field, has high accuracy, and avoids the problem of drift caused by wear between internal components of the existing potentiometer.

[0032] In this example, continue as Figure 1 and Figure 2 As shown, the top of the housing 12 of the photoelectric control device 10 of the present invention has a housing opening 121 connected to the storage compartment, and the rocker 14 is arranged in the storage compartment, and its upper end passes through the housing opening 121 to the outside of the housing, so that the user can manually operate the rocker 14. Furthermore, a corresponding housing hole 122 is provided at the lower end of the housing 12, and the outer shaft 131 of the rotating shaft 13 can be passed through the housing hole 122 of the housing 12.

[0033] Continue as Figure 2 as well as Figure 3As shown, the rocker 14 includes: an active rod 141, a main rod 142 and a reset spring 143. Among them, the bottom end of the active rod 141 is movably located on the bottom opening 111 of the bottom cover 11, and is not fixedly connected to the bottom cover 11. When the rocker 14 is shaken, the motion trajectory of the bottom end of the active rod 141 of the rocker 14 is detected by the photoelectric sensor 15 through the bottom opening 111, so as to determine the moving direction and moving distance of the user's control. The middle part of the main rod 142 is a hollow structure, that is, it has an inner cavity, which can be sleeved on the upper half of the active rod 141. The upper end of the main rod 142 extends out of the outer shell 12 through the shell opening 121 at the top of the outer shell 12, so that the user can control the main rod 142 to achieve the purpose of controlling the movement of the active rod 141. There are protrusions 1421 on both sides of the lower end of the main rod 142, and the protrusions 1421 are penetrated on the rotating shaft 13 to limit and fix the main rod 142. A reset spring 143 is also provided between the movable rod 141 and the main rod 142. The reset spring 143 is sleeved on the movable rod 141, that is, the lower end of the reset spring 143 abuts against the bottom end of the movable rod 141, and the upper end of the reset spring 143 abuts against the step of the inner cavity of the main rod 142. Further, the rotating shaft 13 of the photoelectric control device 10 is a component that can provide support for the 360° rocking of the main rod 142 of the rocker 14. The main body of the rotating shaft 13 is a cavity structure that passes through from top to bottom, and the rocker 14 is longitudinally penetrated in the rotating shaft 13. The outer side of the rotating shaft rod 13 has two opposite outer shafts 131, and the outer shafts 131 of the rotating shaft 13 pass through the shell hole 122 of the outer shell 12, and one of the outer shafts 131 is supported on the support column of the bottom cover 11, and the other outer shaft 131 is supported on the switch 16. The rotating shaft 13 has two opposite shaft holes 132 on the outer side without the outer shaft 131. The protrusions 1421 on both sides of the lower end of the main rod 142 of the rocker 14 are arranged on the two opposite shaft holes 132 of the rotating shaft 13, which can provide a rotatable fulcrum for the rocker 14 to rock. When the user rocks the main rod 142, the protrusions 1421 of the main rod 142 rotate in the shaft hole 132 of the rotating shaft 13, so that the rocker 14 can rotate 360 ​​degrees. Since the reset spring 143 is located between the movable rod 141 and the main rod 142, and when the photoelectric control device 10 is installed, the distance between the rotating shaft 13 and the bottom cover 11 is fixed, so that the reset spring 143 is compressed, that is, it has a certain rebound force. When the user rocks the main rod 142, the reset spring 143 will reset the main rod 142 to the center position under the action of the rebound force, that is, the rocker is returned to the center.

[0034] Continue as Figure 2As shown, the photoelectric control device 10 of the present invention also has a switch 16 and a PCB board 17. The bottom cover 11 has a lower cavity 112 and an upper cavity 113, the photoelectric sensor 15 is arranged in the lower cavity 112 of the bottom cover, the upper cavity 113 is located on one side of the bottom cover 11, the PCB board 17 is arranged under the bottom cover 11, and the photoelectric sensor 15 is located on the PCB board 17 and is connected to the PCB board 17 in communication. The switch 16 is arranged in the upper cavity 113 of the bottom cover 11, and the lower end pin 161 of the switch 16 passes through the bottom of the upper cavity 113 of the bottom cover 11 and is electrically connected to the PCB board 17. The side wall of the bottom cover 11 also has a support column 114, which is opposite to the position of the switch 16, that is, the support column 114 cooperates with a shell hole 122 of the shell 12 to fix the outer shaft 131 on one side of the support shaft 13, and the switch 16 cooperates with another shell hole 112 of the shell 12 to fix the outer shaft 131 on the other side of the support shaft 13. Therefore, in the process of shaking the rocker 14, since the rocker 14 is supported on the shaft 13, the outer shaft of the shaft 13 also squeezes the switch 16 accordingly, thereby realizing corresponding control of the game character, such as squatting. It should be noted that the switch 16 only needs to be pressed slightly to realize the control of the game character, such as 1mm, so it only needs to press the main rod 142 slightly, which is convenient for user operation. Since there is a reset spring 143 between the main rod 142 of the rocker 14 and the movable rod 141, after pressing the main rod 142, it will return to the initial position under the elastic force of the reset spring 143, that is, the rocker returns to the center.

[0035] The utility model uses a photoelectric sensor disposed under the bottom cover 11 to capture a set of continuous images of the bottom end of the movable rod 141 in the rocker 14 at high speed through the bottom opening, and then uses the image analysis module integrated in the photoelectric sensor 15 to analyze and process a series of images captured on the moving trajectory, so as to determine the current control moving direction and moving distance. It should be noted that the image analysis module is a module integrated in the photoelectric sensor 15, which belongs to an existing module, such as the photoelectric sensor of the manufacturer Pixar Technology Co., Ltd., model PAW3311DB-T2MU, PAW3220LU-TJDU and PAW3805EK-CJV1.

[0036] The utility model is described in detail above in conjunction with the embodiments of the drawings.
