DETAILED DESCRIPTION OF THE EMBODIMENTS

The embodiments of the present disclosure is described in detail below in combination with the accompanying drawings.


Embodiment 1

A game controller as shown in FIG. 1 to FIG. 2 includes a gun-shaped body 1, a mode switching mechanism, a screen positioning device and two gamepads. The gun-shaped body 1 is of a gun shape; the two gamepads are located at the lower part of the gun-shaped body 1, and include a front gamepad 2 and a rear gamepad 3 (a muzzle of the gun-shaped body 1 in FIG. 1 is leftward, i.e., a left end of the gun-shaped body 1 is a front end, and a right end of the gun-shaped body 1 is a rear end); and the front gamepad 2 is located on the left side of the rear gamepad 3. Game control devices are arranged on both the front gamepad 2 and the rear gamepad 3, and the game control device on the front gamepad 2 includes a direction control button 14 and a rocker 4. As shown in FIG. 7 to FIG. 8, the game control device on the rear gamepad 3 includes a function control button 5 and a rocker 4. The screen positioning device includes a camera and an infrared light-transmittance sheet which are mounted at the front end of the gun-shaped body.


The upper ends of the two gamepads are connected with the gun-shaped body 1 through a rotation part. As shown in FIG. 3, the rotation part includes a rotating shaft 6 and a sleeve 7 sleeved on the rotating shaft 6. An outer wall of the rotating shaft 6 is provided with a ring slot 8 in a circumferential direction; an inner wall of the sleeve 7 is snapped to a snap ring 9 in the ring slot 8; and the rotating shaft 6 and the sleeve 7 are fixedly connected to the gamepad and the gun-shaped body 1 respectively. Two first magnets 10 are embedded into a surface of the snap ring 9; as shown in FIG. 4, connecting lines between the two first magnets 10 and the axis of the rotating shaft 6 are perpendicular to each other (i.e., α in FIG. 4 is 90 degrees); and two second magnets 11 matching the first magnets 10 are embedded into an inner surface of the ring slot 8. Different magnetic poles of the first magnets 10 and the second magnets 11 are opposite.


As shown in FIG. 3 to FIG. 4, the mode switching mechanism is arranged between the snap ring 9 and the ring slot 8 in the front gamepad 2. The mode switching mechanism is a mechanical switch, which can switch two different game operation modes, i.e., a gamepad operation mode and a gun operation mode. The mode switching mechanism is in communication connection with a processor arranged inside the gun-shaped body 1 (the processor and a connection manner for the processor and the mode switching mechanism are both existing, such as a processor disclosed in the Chinese utility model patent No. CN2778350). The processor communicates with game software. The processor may execute an operation to determine whether a user selects the gamepad operation mode or the gun operation mode, and use the gamepad operation mode or the gun operation mode of the game control device according to the selection of the user.


As shown in FIG. 3 to FIG. 4, the mode switching mechanism specifically includes a first arc-shaped contact sheet 12 and a second arc-shaped contact sheet 13. The first arc-shaped contact sheet 12 and the second arc-shaped contact sheet 13 are located on the same horizontal plane; and connecting lines between the first arc-shaped contact sheet 12 as well as the second arc-shaped contact sheet 13 and the axis of the rotating shaft 6 are perpendicular to each other (i.e., β in FIG. 4 is 90 degrees). The first arc-shaped contact sheet 12 and the second arc-shaped contact sheet 13 are respectively embedded into the surfaces of the snap ring 9 and the ring slot 8.


A working principle of the above-mentioned game controller is as follows.


In the gamepad operation mode, a user operates the front gamepad 2 and the rear gamepad 3 respectively with a left hand and a right hand. The gamepad operation mode is the existing operation mode, such as a gamepad operation mode in xbox and PlayStation. At this time, the two corresponding pairs of first magnets 10 and second magnets 11 attract each other to ensure the stability of the two gamepads in the gamepad operation mode. At the same time, the first arc-shaped contact sheet 12 and the second arc-shaped contact sheet 13 are in no contact, and the mechanical switch is not closed. At this time, the processor determines that the user selects the gamepad operation mode and transmits information to the game software. The game software uses the gamepad operation mode for the user to operate.


In the gun operation mode, after the front gamepad 2 and the rear gamepad 3 are anticlockwise rotated 90 degrees, the shape of the game controller is as shown in FIG. 5. At this time, only one pair of first magnet 10 and second magnet 11 attract each other to ensure the stability of the two gamepads in the gun operation mode. At the same time, the first arc-shaped contact sheet 12 and the second arc-shaped contact sheet 13 are in contact, as shown in FIG. 6, and the mechanical switch is closed. At this time, the processor determines that the user selects the gun operation mode and transmits information to the game software. The game software uses the gun operation mode for the user to operate. The gun operation mode is an existing operation mode, such as a gun operation mode in xbox and PlayStation, and screen aiming positioning equipment is added. For example, according to an infrared light gun positioning method and system disclosed in China invention patent (publication No. CN103949054A), an operation mode is specifically as follows. Four infrared light emitting points are mounted at four corners of a screen; and the front end of the gun-shaped body is provided with a camera and an infrared light-transmittance sheet. The user plays a game in a posture of holding a gun. The user presses the function control button to control the camera to collect images of the infrared light emitting points, and an aiming position of the gun body is calculated by means of image identification and an algorithm.


Meanwhile, in order to improve the comfortableness of user's use of the gamepad, an included angle of 60 degrees (i.e., γ in FIG. 5 is 60 degrees) is reserved between the gamepad and the gun-shaped body 1.


The above-mentioned game controller has the advantages that transformation of the form of the game controller is combined with switching of the game operation modes, so that different operation modes can be switched according to user's needs by rotating the gamepad. Meanwhile, after the gamepad is rotated, the game controller can simulate user's use of a real firearm to play a game, which enhances the vicarious feeling of a game and provides a more comprehensive operation experience for the user.


Embodiment 2

As shown in FIG. 9, Embodiment 2 is improved on the basis of Embodiment 1. The gun-shaped body 1 in Embodiment 2 is cuboid. As such, the game operation mode is still the gun operation mode, but the gun-shaped body 1 does not simulate the appearance of a firearm, which is easy to manufacture and low in cost.


Other structures and the working principle of Embodiment 2 are the same as Embodiment 1.


Embodiment 3

Embodiment 3 is improved on the basis of Embodiment 1. Specifically, in Embodiment 3, an inner wall of the sleeve 7 is provided with a ring slot 8 in a circumferential direction, and an outer wall of the rotating shaft 6 is provided with a snap ring 9 snapped to the ring slot 8. As such, reliable rotatable connection between the sleeve 7 and the rotating shaft 6 can still be ensured.


Other structures and the working principle of Embodiment 3 are the same as Embodiment 1.


Embodiment 4

As shown in FIG. 10 to FIG. 12, Embodiment 4 is improved on the basis of Embodiment 1. The gun-shaped body 1 in Embodiment 4 includes a gun-shaped main body 15 and a clamping body 28 detachably connected to the gun-shaped main body 15. A screen positioning device is arranged on the gun-shaped main body 15, and the lower part of the gun-shaped body 1 is provided with a snap slot matching the shape of the clamping body 28. As shown in FIG. 13, the upper ends of the two gamepads are rotatably connected to the clamping body 28 respectively; the right end of the clamping body 28 is provided with a clamping slot 17; and a position of the gun-shaped body 1 facing the clamping slot 17 is provided with a clamping protrusion 16. A clamping groove 18 is formed in a left end surface of the clamping body 28; a position of the gun-shaped body 1 facing the clamping groove 18 is provided with an accommodating hole 20; the accommodating hole 20 is a stepped hole, and a clamping block 19 is arranged in the accommodating hole 20; the right end of the clamping block 19 extends rightward out of the accommodating hole 20 and is clamped into the clamping groove 18; and the left end of the clamping block 19 runs through the accommodating hole 20 and extends out of the gun-shaped body 1. The clamping block 19 is fixedly connected with a clamping ring 21; the clamping ring 21 is restrained in the accommodating hole 20; a spring 22 is arranged between the clamping ring 21 and the accommodating hole 20; and the spring 22 is sleeved on the clamping block 19.


A user shifts the right end of the clamping block 19 to the right to separate the clamping block 19 from the clamping groove 18, that is, the clamping body 28 may be removed from a side surface of the gun-shaped main body 15 (that is, the clamping body 28 is removed from a direction perpendicular to the drawing in FIG. 10). After the clamping body 28 is removed, the user can play a game in a gamepad form conveniently. When the user intends to play a game in a gun form, the user only needs to clamp the clamping body 28 to the gun-shaped main body 15, which is extremely convenient.


Other structures and the working principle of Embodiment 4 are the same as Embodiment 1.


Embodiment 5

As shown in FIG. 14 to FIG. 15, Embodiment 5 is improved on the basis of Embodiment 1. A difference between Embodiment 5 and Embodiment 1 is that the mode switching mechanism is changed. Specifically, the mechanical switch arranged between the snap ring 9 and the ring slot 8 in the front gamepad 2 is canceled, and a function control button B24 on the rear gamepad 3 is used as a mode switching mechanism. As such, transformation of the form of the game controller and switching of the game operation modes are separated. After the user rotates the gamepad to transform the form of the gamepad, the game operation mode may not be automatically switched (that is, after the user rotates the gamepad, the game operation mode cannot be switched until the function control button B24 is pressed).


The game controller in Embodiment 5 has the advantages that the user presses the function control button B24 and rotates the gamepad to simulate user's use of a real firearm to play a game, which enhances the vicarious feeling of the game and provides a more comprehensive operation experience for the user.


Other structures and the working principle of Embodiment 5 are the same as Embodiment 1.


Embodiment 6

As shown in FIG. 16, Embodiment 6 is improved on the basis of Embodiment 1. A difference between Embodiment 6 and Embodiment 1 is that the mode switching mechanism is changed. Specifically, the mechanical switch arranged between the snap ring 9 and the ring slot 8 in the front gamepad 2 is canceled, and an independent button 27 on the rear gamepad 3 is used as a mode switching mechanism. As such, transformation of the form of the game controller and switching of the game operation modes are separated. After the user rotates the gamepad to transform the form of the gamepad, the game operation mode may not be automatically switched (that is, after the user rotates the gamepad, the game operation mode cannot be switched until the independent button 27 is pressed). In this way, compared with Embodiment 5, the present embodiment takes the independent button 27 as an independent mode switching mechanism, so that an original game function of the function control button B24 cannot be occupied.


Other structures and the working principle of Embodiment 6 are the same as Embodiment 1.


Embodiment 7

As shown in FIG. 17 to FIG. 18, Embodiment 7 is improved on the basis of Embodiment 1. A difference between Embodiment 7 and Embodiment 1 is that the structure of the rotation part is changed. Specifically, the rotating shaft 6 is changed into a drum shape, and the inner wall of the sleeve 7 is changed into a drum shape matching the rotating shaft 6.


Other structures and the working principle of Embodiment 7 are the same as Embodiment 1.


Embodiment 8

As shown in FIG. 19 to FIG. 20, Embodiment 8 is improved on the basis of Embodiment 1. A difference between Embodiment 8 and Embodiment 1 is that the structure of the rotation part is changed. Specifically, the rotating shaft 6 is changed into an inverted cone shape, and the inner wall of the sleeve 7 is changed into an inverted cone shape matching the rotating shaft 6.


Other structures and the working principle of Embodiment 8 are the same as Embodiment 1.


Embodiment 9

Embodiment 9 uses the equipment structure in Embodiment 1 to play a game. A specific game is PLAYERUNKNOWN'S BATTLEGROUNDS. When a user manipulates a virtual character to explore a game map and pick up equipment, a gamepad operation mode is used to play the game. When the user manipulates the virtual character to raise the gun to aim and shoot, a gun operation mode is used to play the game. In the gun operation mode, what is different from a traditional moving screen image is that a center point of the screen image is taken as a shooting point. Gamepad function buttons are used to move and rotate a game image, and a screen positioning point captured by a positioning system is a game shooting point to simulate a real shooting feeling. Images during shooting are similar to Virtua Cop.


As such, the user can use different operation modes to play a game in the same game, and the user can switch the operation mode back and forth between the gun operation mode and the gamepad operation mode, so as to avoid phenomena of anchylosis and muscular soreness and further enhance the operation experience of the user.


The above-mentioned embodiments only express several implementation modes of the present disclosure, and their descriptions are more specific and detailed, but they cannot be understood as limiting the patent scope of the present disclosure. It should be noted that those of ordinary skill in the art can further make various transformations and improvements without departing from the concept of the disclosure, and these transformations and improvements all fall within the protection scope of the present disclosure.
