Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of game handles, in particular to a game handle with a horizontal rotation automatic return control device. BACKGROUND

[0002] A game handle is a common component of an electronic game machine, which controls the virtual character in the game by operating its buttons, etc. In the high-speed development of modern society, the entertainment mode has also begun to diversify. The development process of game machines and their equipment is amazing, and the game equipment on the market is also diverse, among which the game handle is the most diverse.

[0003] During the game, according to the characteristics of the game, the joystick needs to be used to control the character's action in the game, i.e. up, down, left, and right.

[0004] Specifically, when playing a racing game or similar game, the joystick is used to control the direction of the steering wheel in the racing game by turning left or right, which is quite different from the steering control of the steering wheel in real life. For beginners, there is a logical deviation, which requires a lot of practice to master the control of the joystick, but it also affects the experience, i.e. the experience of joystick control is not good.

[0005] The angle of the steering wheel in real life is usually 540-630°, among which the single-turn steering angle of the front wheels is 40-42°, and the steering wheel turns 13-16° for every 1° of the front wheels. However, due to the structural limitations of the joystick itself, the swing angle is usually small, so that after the joystick swings slightly, the front wheels in the game will also turn relatively slightly, and the control accuracy is not high, and the experience is not good. For example, the game handle and its joystick feedback force device disclosed in Chinese patent application No. ZL202010130072.3 clearly shows the assembly structure of the joystick. This type of joystick is limited by the shell, rotating shaft and rotating frame, so that the angle of the joystick swinging left and right is relatively small.

[0006] Specifically, due to the structural limitations of the joystick itself, the swing angle is usually small, and the angle of swinging to one side from the middle position (i.e. the original position) is usually 15-23°, i.e. when the joystick swings 1°, the front wheels in the game turn 2°, that is, the steering ratio of the steering wheel in reality to the front wheels is about 13:1, and the steering ratio of the traditional game handle joystick to the vehicle in the game is about 0.5:1, which makes the control accuracy of the joystick not high, and thus the vehicle in the game often appears to turn too fast and lose control, and the left and right flying problem, which affects the experience of the racing game.

[0007] Therefore, the present application provides the following technical solutions. SUMMARY

[0041] The present application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0042] see Figures 1-20As shown, it is a game handle with horizontal rotation automatic return control device, which comprises a handle main body 1 and a horizontal rotation automatic return control device 2 arranged on the handle main body 1, and the horizontal rotation automatic return control device 2 is electrically connected with the PCB in the handle main body 1 to realize control.

[0043] Specifically, the horizontal rotation automatic return control device 2 comprises a shell 21, a shaft core wheel 22 arranged in the shell 21 and rotatable, a sensing element 23 for detecting / inducing the rotation angle of the shaft core wheel 22, a direction control disc 24 mounted on the upper shaft body 221 of the shaft core wheel 22, and an automatic return mechanism 25 arranged in the shell 21 and used for driving the shaft core wheel 22 to automatically return after counterclockwise / clockwise rotation. The upper shaft body 221 of the shaft core wheel 22 protrudes out of the upper end of the shell 21, and the direction control disc 24 is exposed on the surface of the handle main body 1 and can be rotated horizontally at a large angle. The direction control disc 24 can be rotated horizontally at a large angle, which means that the angle of horizontal rotation is greater than 23°. When the direction control disc 24 is in the original position (i.e. in the initial state position) under the action of the automatic return mechanism 25, the user can place the thumb on the direction control disc 24 and push the direction control disc 24 to rotate counterclockwise / clockwise in the horizontal direction. When the direction control disc 24 rotates, the shaft core wheel 22 also rotates synchronously. At this time, the sensing element 23 detects / induces the rotation angle of the shaft core wheel 22 and feeds back to the PCB in the handle main body 1. When there is no external force on the direction control disc 24, the automatic return mechanism 25 can drive the rotated shaft core wheel 22 and the direction control disc 24 to reset, i.e. the direction control disc 24 automatically returns to the original position (i.e. the initial state position), so as to control the next time. It is extremely convenient to use, and the direction control disc 24 is rotated horizontally to realize operation, which is completely different from the rocker structure in the prior art (for example, ZL202010130072.3), and the control mode is also completely different. The rotation angle of the direction control disc 24 in the present application is not limited, so that the rotation angle of the direction control disc 24 can be designed to be larger, so that the direction control disc 24 can be rotated at a large angle, and the racing control mode is highly simulated, which is consistent with the driving mode / habit in real life. It greatly improves the game level and playing experience, and can improve the control precision, so as to better control the steering wheel in the racing game, effectively avoids the problem that the vehicle is often turned too fast in the game, and the vehicle is out of control, left and right, and the game experience is greatly enhanced, so that the present application has strong market competitiveness.

[0044] Compared with the prior art, the horizontal rotation automatic return control device has a larger angle of the direction control disc 24 to one side, which can effectively improve the control precision. Specifically, the angle of the direction control disc 24 to one side (i.e., in one direction) is about 23-350°, so that the maximum steering ratio of the vehicle in the game can be about 8.5:1, which can improve the control precision by about 17 times compared with the traditional joystick, and can simulate the automatic return operation of the steering wheel in reality, thereby improving the experience of the game.

[0045] Specifically, the direction control disc 24 rotates counterclockwise or clockwise in the horizontal direction by an angle greater than 23°. That is, the direction control disc 24 rotates counterclockwise in the horizontal direction by an angle greater than 23°, and the direction control disc 24 rotates clockwise in the horizontal direction by an angle greater than 23°. This is different from the maximum swing of the joystick in the prior art, which is 23°. In this way, the control precision can be better improved, that is, after the direction control disc 24 rotates by a relatively large angle, the front wheels of the vehicle in the racing game rotate by a small angle, thereby improving the control precision and avoiding the problem that the vehicle in the racing game often turns too fast and loses control, which affects the experience of the racing game. The direction control disc 24 rotates counterclockwise in the horizontal direction by an angle greater than 23° and less than 360°. That is, any value between 24-359° can be achieved, and there is no limitation.

[0046] Further, as a preferred embodiment, the direction control disc 24 rotates counterclockwise or clockwise in the horizontal direction by an angle greater than 180° and less than 360°. That is, the direction control disc 24 rotates counterclockwise in the horizontal direction by an angle greater than 180°, and the direction control disc 24 rotates clockwise in the horizontal direction by an angle greater than 180°. In this way, the control precision can be better improved, that is, after the direction control disc 24 rotates by 13-16°, the front wheels of the vehicle in the racing game rotate by 1°, thereby improving the control precision and avoiding the problem that the vehicle in the racing game often turns too fast and loses control, which affects the experience of the racing game.

[0047] The sensing element 23 is a potentiometer mounted on the circuit board 231, and the lower shaft body 222 of the shaft core wheel 22 is connected with the potentiometer, and the circuit board 231 is mounted on the shell 21. The circuit board 231 is electrically connected with the PCB board in the handle body 1 through a connector or a wire. Of course, the sensing element 23 can also be other types of sensors that can sense the change of the angle, such as an angle sensor, a Hall sensor, a rotation angle sensor, an encoder, etc.

[0048] In combination Figures 1-2As shown, the horizontal rotation automatic return control device 2 and the second control device 3 are integrated and installed in a reversing seat 4, the handle body 1 is provided with a reversing groove 11, and the reversing seat 4 is inlaid and installed in the reversing groove 11, or the reversing seat 4 is inlaid and installed in the reversing groove 11 after being reversed by 180°, so as to adjust the position of the horizontal rotation automatic return control device 2 and the second control device 3 relative to the handle body 1, so as to meet different control habits / requirements of different users, that is, the user can adjust different positions according to the control habits of the user to meet the use requirements. The second control device 3 can be a cross key or a joystick. The present application adopts the second control device 3 which can be a cross key. The reversing seat 4 is arranged on the left side of the handle body 1, and a joystick is arranged on the right side of the handle body 1.

[0049] A gap 111 is arranged at the port of the reversing groove 11, and after the reversing seat 4 is inlaid and fixed in the reversing groove 11, the reversing seat 4 is partially exposed at the gap 111, so that the user can directly pull out the reversing seat 4 from the reversing groove 11 through the gap 111 when reversing is needed, so as to realize the reversing operation, and the use is more convenient.

[0050] A first wire hole 112 is arranged at the bottom of the reversing groove 11, a second wire hole is arranged at the bottom of the reversing seat 4, the wire connected with the horizontal rotation automatic return control device 2 and the second control device 3 passes through the second wire hole and the first wire hole 112 and then extends into the handle body 1 and is electrically connected with the PCB in the handle body 1. When the reversing seat 4 is pulled out from the reversing groove 11, the wire can be pulled out by a certain distance, so as to reversely install the reversing seat 4.

[0051] Combination Figure 3 And Figure 5 As shown, the upper shaft body 221 is fixed with a pressure ring body 26 at the upper end, and the direction control disc 24 is fixed on the pressure ring body 26 in a detachable manner, so that the user can replace the direction control disc 24 of different shapes according to the actual use requirements, and the use is more convenient. Specifically, the pressure ring body 26 is fixed on the upper end of the upper shaft body 221 by a third screw 261, and the upper end of the pressure ring body 26 is polygonal, the lower end of the direction control disc 24 is provided with an inlay groove, the shape of the inlay groove matches the shape of the upper end of the pressure ring body 26, so that the upper end of the pressure ring body 26 is inlaid in the inlay groove to be fixed, so that the direction control disc 24 is fixed on the upper end of the pressure ring body 26.

[0052] Combination Figures 3-5As shown, the first bearing 211 and the second bearing 212 are coaxially arranged on the upper and lower ends of the shell 21 respectively, the upper shaft body 221 of the shaft core wheel 22 is arranged in the first bearing 211 and extends out of the upper end of the shell 21, and the lower shaft body 222 of the shaft core wheel 22 is arranged in the second bearing 212 and extends out of the lower end of the shell 21, so as to ensure the stability of the installation of the shaft core wheel 22 and the concentricity, so that the rotation of the steering wheel in the direction is more smooth and the hand feeling is better.

[0053] The structure of the automatic return mechanism 25 will be described below.

[0054] In combination Figures 3-17 As shown, the automatic return mechanism 25 comprises a first positioning pendulum 253 arranged in the upper part of the inner cavity of the shell 21 and slidable, a first reset element 251 for driving the first positioning pendulum 253 to reset after sliding, a second positioning pendulum 254 arranged in the lower part of the inner cavity of the shell 21 and slidable, and a second reset element 252 for driving the second positioning pendulum 254 to reset after sliding.

[0055] In the initial state, the first reset element 251 drives the first positioning pendulum 253 to be positioned at the initial position, the second reset element 252 drives the second positioning pendulum 254 to be positioned at the initial position, and the shaft core wheel 22 is driven to be positioned at the initial position.

[0056] When the shaft core wheel 22 is driven to rotate in one direction by an external force, only one of the first positioning pendulum 253 or the second positioning pendulum 254 is driven to slide; for example, when the shaft core wheel 22 rotates clockwise, the first positioning pendulum 253 is driven to slide clockwise, at this time, the first reset element 251 is stretched or compressed to form a restoring force, but the second positioning pendulum 254 does not act under the action of the second reset element 252. When the shaft core wheel 22 rotates counterclockwise, the second positioning pendulum 254 is driven to slide counterclockwise, at this time, the second reset element 252 is stretched or compressed to form a restoring force, and the first positioning pendulum 253 does not act under the action of the first reset element 251.

[0057] When the external force disappears, the first reset element 251 provides a restoring force to drive the first positioning pendulum 253 to slide in the opposite direction to drive the shaft core wheel 22 to rotate in the opposite direction, so as to return the shaft core wheel 22; or the second reset element 252 provides a restoring force to drive the second positioning pendulum 254 to slide in the opposite direction to drive the shaft core wheel 22 to rotate in the opposite direction, so as to return the shaft core wheel 22.

[0058] The upper part of the inner cavity of the shell 21 is provided with a first back-to-normal positioning surface 2001 for blocking the first positioning pendulum 253, and the lower part of the inner cavity of the shell 21 is provided with a second back-to-normal positioning surface 2002 for blocking the second positioning pendulum 254, the first back-to-normal positioning surface 2001 and the second back-to-normal positioning surface 2002 being in the same vertical plane; in the initial state, the first reset element 251 drives the first positioning pendulum 253 to be positioned at the initial position (i.e. the position where the first positioning pendulum 253 is in contact with the first back-to-normal positioning surface 2001), and the second reset element 252 drives the second positioning pendulum 254 to be positioned at the initial position, thereby driving the shaft core wheel 22 to be positioned at the initial position (i.e. the position where the second positioning pendulum 254 is in contact with the second back-to-normal positioning surface 2002).

[0059] The shaft core wheel 22 is non-fixedly assembled with the first positioning pendulum 253 and the second positioning pendulum 254. Specifically, the upper end of the shaft core wheel 22 is provided with a first driving part 223, which is in contact with the side surface of the first positioning pendulum 253 and can only drive the first positioning pendulum 253 to slide in one direction. For example, when the shaft core wheel 22 rotates in the clockwise direction, the first driving part 223 is in contact with the side surface of the first positioning pendulum 253 to push the first positioning pendulum 253 to slide in the clockwise direction; when the shaft core wheel 22 rotates in the counterclockwise direction, the first driving part 223 is separated from the side surface of the first positioning pendulum 253, and the first positioning pendulum 253 does not slide. The upper end of the shaft core wheel 22 is provided with a second driving part 224, which is in contact with the side surface of the second positioning pendulum 254 and can only drive the second positioning pendulum 254 to slide in one direction. For example, when the shaft core wheel 22 rotates in the counterclockwise direction, the second driving part 224 is in contact with the side surface of the second positioning pendulum 254 to push the second positioning pendulum 254 to slide in the counterclockwise direction; when the shaft core wheel 22 rotates in the clockwise direction, the second driving part 224 is separated from the side surface of the second positioning pendulum 254, and the second positioning pendulum 254 does not slide.

[0060] In order to enable the first driving part 223 to stably push the first positioning pendulum 253 to slide during the rotation of the shaft core wheel 22, and enable the first driving part 223 to smoothly separate from the first positioning pendulum 253 when rotating in the opposite direction, the following design is made: one side of the first positioning pendulum 253 is provided with a first open slot 2530 corresponding to the first driving part 223 of the upper end of the shaft core wheel 22, when the first driving part 223 enters the first open slot 2530 and pushes the first positioning pendulum 253 to slide, the first driving part 223 will not slip or dislocate relative to the first positioning pendulum 253 to affect the sliding of the first positioning pendulum 253, and the first driving part 223 can smoothly separate from the first positioning pendulum 253 when rotating in the opposite direction.

[0061] In order to enable the second driving part 224 to stably push the second positioning pendulum 254 to slide in the process of rotating with the shaft core wheel 22, and enable the second driving part 224 to smoothly separate from the second positioning pendulum 254 when rotating in the opposite direction, the following design is made: the second positioning pendulum 254 is provided with a second open slot 2540 corresponding to the second driving part 224 at the lower end of the shaft core wheel 22, when the second driving part 224 enters the second open slot 2540 and pushes the second positioning pendulum 254 to slide, the second driving part 224 will not slip or dislocate relative to the second positioning pendulum 254 to affect the sliding of the second positioning pendulum 254, and the second driving part 224 can smoothly separate from the first positioning pendulum 25 when rotating in the opposite direction.

[0062] The first reset element 251 and the second reset element 252 are any one of a tension spring, a clock spring, a rubber band, and a torsion spring.

[0063] Specifically, as shown in combination with 3-13, when the first reset element 251 and the second reset element 252 are both tension springs, it is the first automatic return mechanism, the upper and lower parts of the inner cavity of the shell 21 are respectively provided with a first circular arc sliding groove 213 and a second circular arc sliding groove 214, the first reset element 251 and the first positioning pendulum 253 are both arranged in the first circular arc sliding groove 213, and one end of the first reset element 251 is fixedly connected with the first circular arc sliding groove 213 through a first screw 201, the other end of the first reset element 251 is connected with the first positioning pendulum 253, and one side of the first positioning pendulum 253 is provided with a first open slot 2530 corresponding to the first driving part 223 at the upper end of the shaft core wheel 22; the second reset element 252 and the second positioning pendulum 254 are both arranged in the second circular arc sliding groove 214, and one end of the second reset element 252 is fixedly connected with the second circular arc sliding groove 214 through a second screw 202, the other end of the second reset element 252 is connected with the second positioning pendulum 254, and one side of the second positioning pendulum 254 is provided with a second open slot 2540 corresponding to the second driving part 224 at the lower end of the shaft core wheel 22; preferably, the shaft center of the shaft core wheel 22 is on the same straight line as the second driving part 224 and the first driving part 223.

[0064] The installation direction of the first reset element 251 and the second reset element 252 is opposite, so as to provide force in two directions, that is, the first reset element 251 pulls the first positioning pendulum 253 in one direction, for example, in the clockwise direction, and the corresponding second reset element 252 pulls the second positioning pendulum 254 in one direction, for example, in the counterclockwise direction, so that the first reset element 251 and the second reset element 252 pull the first positioning pendulum 253 and the second positioning pendulum 254 in two directions, and the first positioning pendulum 253 and the second positioning pendulum 254 position the hub 22, so that the hub 22 is in the original position / initial position. More specifically, in this state, the first driving part 223 of the hub 22 enters the first open slot 2530, and the second driving part 224 of the hub 22 enters the second open slot 2540, that is, the first reset element 251 and the second reset element 252 provide force to the first driving part 223 and the second driving part 224 respectively, so as to ensure that, under the action of no external force, the first driving part 223 of the hub 22 is positioned in the first open slot 2530, and the second driving part 224 of the hub 22 is positioned in the second open slot 2540, and the hub 22 is pressed in two directions, so that the hub 22 is positioned and cannot rotate, and is in the original position / initial position.

[0065] The upper end of the first positioning pendulum 253 is provided with a first arc-shaped rail 2533 protruding upward, which is embedded in the first rail groove 2131 provided at the bottom of the first circular arc sliding groove 213, and slides more stably, and the inner wall of one side of the first rail groove 2131 serves as a first return positioning surface 2001; the lower end of the second positioning pendulum 254 is provided with a second arc-shaped rail 2543 protruding downward, which is embedded in the second rail groove 2141 provided at the bottom of the second circular arc sliding groove 214, and slides more stably, and the inner wall of one side of the second rail groove 2141 serves as a second return positioning surface 2002, and the first return positioning surface 2001 and the second return positioning surface 2002 are in the same vertical plane.

[0066] The original position / initial position refers to the balance state when the direction control disc does not rotate.

[0067] The first reset element 251 pulls the first positioning pendulum 253 in one direction, and the first positioning pendulum 253 is blocked by the first return positioning surface 2001 and positioned here. Correspondingly, the second reset element 252 pulls the second positioning pendulum 254 in one direction, and the second positioning pendulum 254 is blocked by the second return positioning surface 2002 and positioned here. Therefore, in the initial state, the force of the first reset element 251 drives the first positioning pendulum 253 to be positioned in the initial position (i.e. the position where the first positioning pendulum 253 contacts the first return positioning surface 2001), and the force of the second reset element 252 drives the second positioning pendulum 254 to be positioned in the initial position, thereby driving the shaft core wheel 22 to be positioned in the initial position (i.e. the position where the second positioning pendulum 254 contacts the second return positioning surface 2002).

[0068] When an external force drives the direction control disc 24 to rotate clockwise, and drives the shaft core wheel 22 to rotate in the clockwise direction synchronously, the first driving part 223 of the shaft core wheel 22 contacts the side surface of the first positioning pendulum 253 to push the first positioning pendulum 253 to slide in the clockwise direction, and at this time, the first reset element 251 is stretched to have a restoring force; and the second driving part 224 of the shaft core wheel 22 is separated from the side surface of the second positioning pendulum 254, and at this time, the second positioning pendulum 254 does not slide. After the external force disappears, the first reset element 251 is retracted under its own restoring force, and at the same time, the first positioning pendulum 253 is reset, so that the shaft core wheel 22 and the direction control disc 24 are automatically returned to the initial position, i.e. automatically returned to the initial position.

[0069] Alternatively, when an external force drives the direction control disc 24 to rotate counterclockwise, and drives the shaft core wheel 22 to rotate in the counterclockwise direction synchronously, the first driving part 223 is separated from the side surface of the first positioning pendulum 253, and at this time, the first positioning pendulum 253 does not slide. The second driving part 224 of the shaft core wheel 22 contacts the side surface of the second positioning pendulum 254 to push the second positioning pendulum 254 to slide in the counterclockwise direction, and the second reset element 252 is stretched to have a restoring force. After the external force disappears, the second reset element 252 is retracted under its own restoring force, and at the same time, the second positioning pendulum 254 is reset, so that the shaft core wheel 22 and the direction control disc 24 are automatically returned to the initial position, i.e. automatically returned to the initial position.

[0070] The shell 21 comprises a bottom shell 205 and a surface shell 206 which are fixed together, and the bottom shell 205 is provided with the second circular arc sliding groove 214; and the surface shell 206 is provided with the first circular arc sliding groove 213.

[0072] The side of the second positioning pendulum 254 is provided with a second connecting part 2541 for connecting with a second hook body 2521 at the other end of the second reset element 252, and the second hook body 2521 can directly hook the second connecting part 2541, which is extremely convenient to assemble.

[0073] When the first reset element 251 and the second reset element 252 are both rubber bands, the assembly structure of the rubber bands is the same as that of the tension spring, and the principle and effect are also the same.

[0074] When the first reset element 251 and the second reset element 252 are both clockwork springs, it is a second automatic return mechanism, which is combined with Figures 14-17 As shown, the upper part of the inner cavity of the shell 21 is provided with a first eccentric ring body 215 and a third circular arc sliding groove 216 located outside the first eccentric ring body 215, the first reset element 251 is sleeved on the periphery of the first eccentric ring body 215, wherein the inner end of the first reset element 251 is fixedly connected with the outer wall of the first eccentric ring body 215, the first positioning pendulum 253 is slidably installed in the third circular arc sliding groove 216, and the outer end of the first reset element 251 extends into the third circular arc sliding groove 216 to be fixedly connected with the outer wall of the first positioning pendulum 253, one side of the first positioning pendulum 253 is provided with a first open slot 2530 corresponding to the first driving part 223; the lower part of the inner cavity of the shell 21 is provided with a second eccentric ring body 217 and a fourth circular arc sliding groove 218 located outside the second eccentric ring body 217, the second reset element 252 is sleeved on the periphery of the second eccentric ring body 217, wherein the inner end of the second reset element 252 is fixedly connected with the outer wall of the second eccentric ring body 217, the second positioning pendulum 254 is slidably installed in the fourth circular arc sliding groove 218, and the outer end of the second reset element 252 extends into the fourth circular arc sliding groove 218 to be fixedly connected with the outer wall of the second positioning pendulum 254, one side of the second positioning pendulum 254 is provided with a second open slot 2540 corresponding to the second driving part 224;

[0075] The installation direction of the first reset element 251 and the second reset element 252 is opposite, so as to provide force in two directions, that is, the first reset element 251 pulls the first positioning pendulum 253 in one direction, for example, in the clockwise direction, and the corresponding second reset element 252 pulls the second positioning pendulum 254 in one direction, for example, in the counterclockwise direction, so that the first reset element 251 and the second reset element 252 pull the first positioning pendulum 253 and the second positioning pendulum 254 in two directions, and the first positioning pendulum 253 and the second positioning pendulum 254 position the hub 22, so that the hub 22 is in the original position / initial position. More specifically, in this state, the first driving part 223 of the hub 22 enters the first open slot 2530, and the second driving part 224 of the hub 22 enters the second open slot 2540, that is, the first reset element 251 and the second reset element 252 provide force to the first driving part 223 and the second driving part 224 respectively, so as to ensure that, under the action of no external force, the first driving part 223 of the hub 22 is positioned in the first open slot 2530, and the second driving part 224 of the hub 22 is positioned in the second open slot 2540, and the hub 22 is pressed in two directions, so that the hub 22 is positioned and cannot rotate, and is in the original position / initial position.

[0076] The upper end of the first positioning pendulum 253 is provided with a first arc-shaped rail 2533 protruding upward, which is embedded in the first rail slot 2131 arranged at the bottom of the third circular arc sliding groove 216, and slides more stably, and the inner wall of one side of the first rail slot 2131 serves as a first return positioning surface 2001; the lower end of the second positioning pendulum 254 is provided with a second arc-shaped rail 2543 protruding downward, which is embedded in the second rail slot 2141 arranged at the bottom of the fourth circular arc sliding groove 217, and slides more stably, and the inner wall of one side of the second rail slot 2141 serves as a second return positioning surface 2002, and the first return positioning surface 2001 and the second return positioning surface 2002 are in the same vertical plane.

[0077] The original position / initial position refers to the balance state when the direction control disc does not rotate.

[0078] The first reset element 251 pulls the first positioning pendulum 253 in one direction, and the first positioning pendulum 253 is blocked by the first return positioning surface 2001 and positioned here. Correspondingly, the second reset element 252 pulls the second positioning pendulum 254 in one direction, and the second positioning pendulum 254 is blocked by the second return positioning surface 2002 and positioned here. Therefore, in the initial state, the force of the first reset element 251 drives the first positioning pendulum 253 to be positioned at the initial position (i.e. the position where the first positioning pendulum 253 is in contact with the first return positioning surface 2001), and the force of the second reset element 252 drives the second positioning pendulum 254 to be positioned at the initial position, thereby driving the shaft core wheel 22 to be positioned at the initial position (i.e. the position where the second positioning pendulum 254 is in contact with the second return positioning surface 2002).

[0079] The inner wall of one side of the third circular arc sliding groove 216 serves as the first return positioning surface 2001, and the inner wall of one side of the fourth circular arc sliding groove 218 serves as the second return positioning surface 2002; the first return positioning surface 2001 and the second return positioning surface 2002 are in the same vertical plane;

[0080] When the external force drives the direction control disc 24 to rotate clockwise, and drives the shaft core wheel 22 to rotate in the clockwise direction synchronously, the first driving part 223 of the shaft core wheel 22 is in contact with the side surface of the first positioning pendulum 253 to push the first positioning pendulum 253 to slide in the clockwise direction, at this time, the first reset element 251 is stretched to have a restoring force; and the second driving part 224 of the shaft core wheel 22 is separated from the side surface of the second positioning pendulum 254, at this time, the second positioning pendulum 254 does not slide. After the external force disappears, the first reset element 251 is retracted under its own restoring force, and at the same time, the first positioning pendulum 253 is reset, so that the shaft core wheel 22 and the direction control disc 24 are automatically returned to the initial position, i.e. automatically returned to the initial position.

[0081] Alternatively, when the external force drives the direction control disc 24 to rotate counterclockwise, and drives the shaft core wheel 22 to rotate in the counterclockwise direction synchronously, the first driving part 223 is separated from the side surface of the first positioning pendulum 253, at this time, the first positioning pendulum 253 does not slide. The second driving part 224 of the shaft core wheel 22 is in contact with the side surface of the second positioning pendulum 254 to push the second positioning pendulum 254 to slide in the counterclockwise direction, and the second reset element 252 is stretched to form a restoring force. After the external force disappears, the second reset element 252 is retracted under its own restoring force, and at the same time, the second positioning pendulum 254 is reset, so that the shaft core wheel 22 and the direction control disc 24 are automatically returned to the initial position, i.e. automatically returned to the initial position.

[0082] The inner wall of the upper portion of the inner cavity of the shell 21 is provided with a first arc-shaped protrusion 203 corresponding to the side of the second eccentric ring body 217 with the largest radius, and the first arc-shaped protrusion 203 is in abutment with the outermost circle of the first reset element 251, so as to prevent the first reset element 251 from being excessively loose, and to ensure the elastic force of the first reset element 251.

[0084] Specifically, as shown in combination with 18-20, when the first reset element 251 and the second reset element 252 are both torsion springs, it is the third automatic return mechanism, the assembly structure of which is basically the same as that of the clock spring, the principle of controlling the return of the first and second positioning pendulums 253 and 254 is also basically the same, and the technical effects achieved are also the same, which will not be described here one by one.

[0085] To sum up, the structure of the horizontal rotation automatic return control device 2 in the application is completely different from the rocker structure in the prior art (for example, ZL202010130072.3), and the control method is also completely different, which is a completely new design. When the direction control disc 24 in the horizontal rotation automatic return control device 2 is not acted on by external force, the direction control disc 24 is in the original position (i.e. in the initial state position) under the action of the automatic return mechanism 25. In the use process, the user can place the thumb on the direction control disc 24 and push the direction control disc 24 to rotate in the horizontal direction counterclockwise / clockwise. When the direction control disc 24 rotates, the shaft core wheel 22 also rotates synchronously. At this time, the sensing element 23 detects / induces the rotation angle of the shaft core wheel 22 and feeds back to the PCB in the handle main body 1. When there is no external force on the direction control disc 24, the automatic return mechanism 25 can drive the rotated shaft core wheel 22 and the direction control disc 24 to reset, that is, the direction control disc 24 can automatically return to the original position (i.e. automatically return to the initial state position), so as to control next time. It is extremely convenient to use, and the direction control disc 24 is operated by horizontal rotation, and the rotation angle is not limited, so that the rotation angle of the direction control disc 24 can be designed to be larger, so that the direction control disc 24 can realize large-angle rotation, and highly simulates the racing control method, which is consistent with the driving method / habit in real life. It greatly improves the game operation degree and playing experience, and can improve the control precision, so as to better control the steering wheel in the racing game, which can effectively avoid the problem that the vehicle in the game often turns too fast and loses control, greatly enhances the game experience, and makes the application have strong market competitiveness.

[0086] Of course, the above only describes specific embodiments of the application, and does not limit the scope of the application. Any equivalent changes or modifications made according to the structure, features and principles described in the application patent range should be included in the application patent range.
