Description

Mobile game controller

The present invention relates to a mobile game controller, and more particularly to a mobile game controller using a USB interface. Background technique

With the further enhancement of the game function of the mobile phone platform, the use of the mobile phone's own keyboard to play the game has not met the needs of the user, so a dedicated mobile game controller has appeared. At present, there are two main types of dedicated mobile game controllers. One is a controller with a mechanical structure, which is equipped with a device with a common game joystick button arrangement on the keyboard of the mobile phone. The corresponding functions on the keyboard of the mobile phone are operated to achieve the control function, but the mechanical structure of the device determines the disadvantage of high error rate, and it is not suitable for mobile phones of different appearances. The other is a game controller specially designed by mobile phone manufacturers for their own mobile phones. Although this controller can realize the game operation function very well, since each mobile phone manufacturer uses different interfaces, a game controller can only correspond to one. A mobile phone or a brand of mobile phone lacks versatility.

In addition, the game is very battery-intensive. If you rely on the mobile phone battery to supply power during the game, it will greatly increase the power consumption of the mobile phone, which brings a lot of inconvenience to users outdoors. Summary of the invention

The present invention provides a universal mobile phone game controller with a battery backup function to solve the above technical problems.

The technical solution adopted by the present invention to solve the above technical problem is to provide a mobile game controller for connecting with a mobile phone and controlling a mobile game, which comprises a keyboard body with a control keyboard, a USB interface provided on the keyboard body, And a control circuit disposed in the keyboard body, the control circuit includes an MCU connected to the control keyboard and a USB control chip connected to the MCU, and the USB control chip is connected to the USB interface.

The above USB control chip can be based on the USB 1.1 or USB 2.0 protocol, or the OTG control chip can be used based on the USB OTG protocol.

The above-described mobile game controller may further include a battery connected to the control keyboard and the MCU for powering them. The battery can also be connected to the mobile phone via a USB cable, including The mobile phone power management chip that can identify the battery can control the battery to power the mobile phone when needed, for example, during game play or when the mobile phone has insufficient power, so as to save battery consumption of the mobile phone itself.

The mobile game controller of the invention expands the versatility of the mobile phone by adopting the USB interface, and the backup battery function can save the battery consumption of the mobile phone itself and facilitate the outdoor use of the mobile phone. BRIEF abstract

Features and capabilities of the present invention are further described by the following examples and the accompanying drawings.

1 is an external view of a mobile game controller of the present invention;

2 is a block diagram showing the structure of a mobile game controller of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION

Referring to FIG. 1, 2, the mobile game controller of the present invention includes a control keyboard 10 and a USB interface 40 on a disk 100. The disk body 100 is provided with an MCU 20, a USB control chip 30, and a battery 50. The control keypad 10 has a similar appearance and key setting as a conventional gamepad, and is coupled to the MCU 20 of the controller for transmitting the generated key signals to the MCU 20. The MCU 20 is mainly responsible for receiving signals transmitted from the control keyboard 10, converting them into digital signals and outputting them through their I/O ports. The USB control chip 30 is connected to the I/O port of the MCU 20, receives a key signal converted into a digital signal, and transmits it to the mobile phone 60 via the USB interface 40 connected thereto.

In one embodiment, the USB control chip 30 may be a USB 1.1 or USB 2.0 based control chip, and the USB control chip 30 is a control chip with a USB HOST function. Accordingly, the connected mobile phone 60 includes a USB. SLAVE function USB control chip to achieve data transfer between the two.

In another embodiment, the USB control chip 30 can be based on the OTG control chip of the USB OTG (On-The-Go) protocol, and the OTG realizes data transmission between various devices without the Host. There is no Host or Slave between the devices of the USB OTG protocol. Due to this feature, the USB OTG protocol will be widely used in various devices, such as printers, digital cameras, mobile phones, PDAs, etc., so the mobile game controller of the present invention utilizes the USB OTG protocol to connect with a mobile phone supporting such a protocol, which is advantageous. Expand its versatility. In addition, the USB OTG protocol has lower power consumption, which is beneficial for portable devices. The battery 50 is a power source for the mobile game controller, which is connected to the control keyboard 10 and the MCU 20 to supply power to the two components. At the same time, in order to reduce the consumption of the mobile phone's own battery, the battery 50 also has the function of supplying power to the mobile phone. It is connected to the mobile phone through the power cable of the USB interface 40, and the power management chip (not shown) inside the mobile phone 60 can identify the battery 50 and As the power source of the mobile phone, the battery 50 can supply power to the mobile phone through the USB interface 40. Thus, when playing a mobile game through the mobile game controller, the battery 60 can be powered by the battery 50 in the controller without consuming the battery of the mobile phone 60 itself; and when the battery of the mobile phone 60 itself is insufficient, the battery can also be used. 50 pairs of mobile phones 60 are powered, as a backup battery for the mobile phone 60. It should be noted that the mobile game controller can also be connected to the mobile phone through the power cable of the USB interface 40 by using a separate backup battery to power the mobile phone.

The embodiments of the present invention are disclosed above, but they are not intended to limit the present invention, and various equivalent modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of the invention. The scope of protection of the invention should be defined by the appended claims. Industrial applicability

The mobile game controller of the invention adopts the widely used USB protocol (or USB 0TG protocol), has high versatility and compatibility, and has a backup battery function to save the battery consumption of the mobile phone itself, and is convenient for the mobile phone. Outdoor use.
