Description

Technical Field

[0001] The utility model relates to the technical field of game handles, and more particularly to a handle button automatic switching circuit and a game handle. Background Art

[0002] The game controller includes a shell, direction keys and ABXY function keys arranged on the shell, and a corresponding circuit board is also provided in the shell to transmit the corresponding control signals. Each button of the ABXY function key has a different function, and the user can control the game character to produce corresponding actions by coordinating multiple buttons. There are two layouts of ABXY key positions of the game controllers currently on the market: ABXY key layout and BAYX key layout. The layout order of the two is different. The ABXY key layout is suitable for XBOX and PC platforms, and BAYX is suitable for NS platform, but the game controller can only meet the needs of a single key layout. If the user uses a game controller with a BAYX layout to play PC games, the key positions are exactly opposite, which will bring a very bad experience to the user. In order to improve the gaming experience, users usually buy game controllers suitable for different game platforms, resulting in a waste of resources.

[0003] The prior art provides a solution for switching ABXY key values, in which a motor drives an adjustment disk to rotate, thereby displaying two key layouts, ABXY and BAYX. However, this technology has the following disadvantages. The motor needs to be switched manually. First, the user experience is not good. Second, during the motor switching process, if an abnormality occurs such as the MCU program running away or the battery is out of power, the adjustment disk will stop in the middle and the ABXY key position display will be disordered. Even if the subsequent abnormality is resolved (such as resetting the single-chip microcomputer, etc.), the adjustment disk will still stop in the middle and the ABXY key position will still be disordered. In order to solve this problem, the user needs to manually switch again, which is very troublesome to adjust, making it psychologically unacceptable to the user. Utility Model Content

[0042] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting this patent;

[0043] In order to better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size;

[0044] It is understandable to those skilled in the art that some well-known structures and descriptions thereof may be omitted in the drawings.

[0045] The technical solution of the present utility model is further described below with reference to the accompanying drawings and embodiments.

[0046] Example

[0047] This embodiment provides a handle button automatic switching circuit, such as Figure 1 As shown, it includes an MCU control subcircuit, a motor drive subcircuit, a motor, a light source module, and an adjustment disk, wherein:

[0048] The input end of the MCU control subcircuit is connected to the external server, and the output end of the MCU control subcircuit is electrically connected to the input end of the motor drive subcircuit and the light source module respectively;

[0049] The output end of the motor driving sub-circuit is electrically connected to the motor;

[0050] The output shaft of the motor is fixedly connected to the adjusting disk;

[0051] The adjustment disk is provided with a plurality of light-transmitting areas, and the light emitted by the light source module passes through the plurality of light-transmitting areas of the adjustment disk to display the corresponding key positions.

[0052] In this embodiment, the external server can be a game platform. When the MCU control sub-circuit is connected to the external server, it can control the motor drive sub-circuit to drive the motor according to different game platforms, so that the adjustment disk rotates to realize the switching of the key layout.

[0053] In a further embodiment, the input end of the MCU control sub-circuit is connected to an external server via wired or wireless connection.

[0054] In the prior art, after the external server is connected to the MCU control subcircuit, the external server will automatically identify the device. The specific identification principle is:

[0055] When the game controller is connected to the game platform via a wired connection, the controller will be described as a specific device through the USB descriptor. The game platform will enumerate the specific device. If the controller does not support the game platform, the enumeration will time out. At this time, the controller will be described as a device that supports another game platform and enumerate with the game platform again. If the enumeration times out, it will be described as a device that supports another game platform until the enumeration is successful. When the enumeration is successful, the controller will know which game platform the current game platform is. At this time, the game controller will use the USB protocol to parse out which platform the connected game platform belongs to. When the game controller is connected to the game platform wirelessly, it will broadcast wirelessly in the mode of the game platform. For example, when connected to the NS host, it will broadcast wirelessly in NS mode.

[0056] When the game controller knows which specific game platform it is connected to, the MCU controls the sub-circuit and automatically controls the motor drive circuit to drive the motor to rotate. The motor will drive the adjustment dial to rotate, thereby displaying the ABXY key layout adapted to the game platform.

[0057] Even if anomalies occur during the motor switching process, such as the MCU program running away or the battery is dead, after the anomaly is resolved (such as the MCU is reset, etc.), when the game controller is reconnected to each game platform, the MCU will still automatically control the ABXY key distribution without user intervention.
