The smart peripherals of the present invention will be described in detail with reference to Figures 1-19.

In this embodiment, the smart peripheral includes: a communication component, a rectifier circuit unit, a voltage stabilizing unit, a Bluetooth unit, an MCU (Microcontroller Unit), and an input unit. The communication component includes NFC (Near Field Communication). Field communication) unit. The MCU is connected to the NFC unit, rectifier circuit unit, voltage stabilizing unit, and input unit. The input and output ends of the rectifier circuit unit are respectively connected to the NFC unit and voltage stabilizing unit. Smart peripherals connect the radio frequency through the NFC unit. The signal is converted into a current, and the current is rectified and stabilized by the rectifier circuit unit and the voltage stabilizing unit, respectively, to supply power to the MCU, and is connected to the intelligent terminal through the communication component.

The smart peripheral of this embodiment converts the radio frequency signal sent by the smart terminal into current power supply through the NFC unit to complete power supply to the MCU and other components of the smart peripheral (such as supplying power to the Bluetooth unit). At the same time, the NFC unit can be used as a communication unit, or a powered Bluetooth unit can be used as a communication device for smart peripherals to communicate with other smart terminals.

In this embodiment, the radio frequency signal sent by the smart terminal refers to the 13.56 MHz radio frequency signal used by the NFC unit for communication.

In this embodiment, smart terminals are mobile phones and other devices with NFC devices.

In this embodiment, the smart peripheral is any one of a game controller, a mobile phone case with control, a mobile phone case powered by NFC, a peripheral device powered by NFC, and a light-emitting mobile phone case.

In the following, taking the smart terminal as a mobile phone and the smart peripheral as a game controller as an example, the smart peripheral of the present invention will be described in detail.

In this embodiment, when the mobile phone does not sense the NFC tag, the smart terminal usually defaults to send out RF signals with insufficient frequency or strength due to energy conservation considerations. At this time, the power of the electrical signal converted by the NFC unit is too low and cannot be used for activation. Or for use by peripherals. Therefore, the NFC unit includes a sustaining circuit, which includes a coil and an NFC tag. When the mobile phone contacts the smart peripheral, the mobile phone senses the NFC tag, thereby triggering the mobile phone to send out a stable and powerful RF signal to obtain the smart peripheral The current used.

In this embodiment, the sustaining circuit is a part of the NFC unit. In other embodiments, the sustaining circuit can also be an independent module (such as an NFC tag sticker) with an NFC tag chip and a coil. In this embodiment, the reversing block 13 and the handle 7 are circular. In other embodiments, the reversing block 13 and the handle 7 may also have other shapes, which are not limited here.

In this embodiment, in order to convert the radio frequency signal transmitted by the mobile phone into electric current, the NFC unit further includes at least one resonant antenna or conversion coil, and the radio frequency signal is converted into electric current through the resonant antenna or the conversion coil. The coil of the holding circuit can also be used to convert the radio frequency signal of the mobile phone into electric current.

Since the current converted by NFC is alternating current, it needs to be converted to direct current before it can be used. In this embodiment, the rectifier circuit unit receives the alternating current transmitted by the NFC unit and converts it into direct current through the rectifier circuit unit; the rectifier circuit unit includes full bridge rectification Circuit and N double voltage rectifier circuit, N≧1.

In this embodiment, since the NFC unit includes multiple antennas or coils for energy conversion, the signal strength collected by it will be different in order of the distance from the area where the signal is transmitted, passing through different antennas or coils. The voltage of the converted electrical signal will also be different. The rectifier circuit unit is required to perform different processing according to the voltage output by the antenna or coil. According to the voltage situation, the rectification is carried out through one of full-wave rectification, voltage doubler rectification or a combination of the two. Among them, the full-wave rectification has a high energy conversion rate and a small voltage change (for example, half-wave only has an energy conversion efficiency of <50%); voltage doubler rectification can amplify the voltage of the electrical signal to make it less lossy under high voltage. Since the electrical signal is attenuated in sequence, the electrical signal with a higher voltage can be processed without voltage doubling and rectification.

After the electrical signals output by multiple antennas or coils are rectified by the rectifier circuit unit, the rectified electrical signals are output in parallel.

Because the voltage or current of the multiple electrical signals after rectification may be different (for example, the voltage and current may be different between the voltage and current after the voltage doubler rectification and the voltage without voltage doubler rectification). Therefore, the voltage output by the rectifier circuit unit may be unstable, and the voltage stabilization unit needs to be stabilized.

In this embodiment, the voltage stabilizing unit includes a DC-DC circuit and/or an LDO circuit, and the DC-DC circuit is respectively associated with a rectifier circuit unit and an MCU. The LDO circuit can be connected to the DC-DC circuit or directly connected to the rectifier circuit unit.

The DC-DC circuit can output low-voltage and high-current electrical signals, which can reduce load loss and provide the intelligent peripherals with the voltage required for their work to ensure the normal operation of the intelligent peripherals. For example, when the chip working voltage of the smart peripheral is 1.8V, the DC-DC circuit can output a voltage of 1.8V, so as to meet the working voltage requirements of the smart peripheral while providing more stable and sufficient current protection.

In this embodiment, the DC-DC circuit includes a DC-DC chip and a peripheral component circuit, and the uneven voltage output by the rectifier circuit unit is converted into a stable voltage and current output through the DC-DC circuit, thereby reducing the loss of smart peripherals .

In this embodiment, the LDO circuit is composed of a circuit that includes an LDO chip and peripheral components. The purpose is to output the voltage linearly to provide devices that require less power ripple and higher accuracy of electrical signals, such as smart The joystick of the controller collected by ADC in the peripheral.

In this embodiment, the LDO circuit can be directly connected to the rectifier circuit unit or connected to the rectifier circuit unit through a DC-DC circuit. The difference is that the LDO circuit is a consumable element, and the conversion efficiency of the electrical signal is low after it is directly connected to the rectifier circuit unit; when the electrical signal is transmitted to the LDO circuit after being stabilized by the DC-DC unit, the conversion efficiency of the LDO circuit is high.

In this embodiment, the smart peripheral receives the input signal through the input unit. The input unit includes at least one of a button and/or joystick, a gyroscope, and other devices for inputting information to the MCU. The input unit is respectively connected to the MCU and the voltage stabilizing unit, and the voltage stabilizing unit supplies power to the input unit.

In a specific embodiment, the input unit includes a joystick and a button, where the joystick is connected to the LDO circuit, and power is supplied to the joystick through the LDO circuit; the buttons and the joystick are respectively connected to the MCU, and the MCU uses IO, GPIO, and ADC. , SPI, I2C, UART and other devices complete the collection of input signals.

In this embodiment, the smart peripheral includes a display unit, the display unit is respectively connected to the MCU and the DC-DC circuit, and the MCU displays the working status of the smart peripheral through the display unit.

In this embodiment, the display unit may be any of LCD and LED display screen.

In this embodiment, the communication component further includes a Bluetooth unit. After the MCU and the Bluetooth unit obtain the current input by the voltage stabilizing unit, the Bluetooth unit and the smart terminal can be quickly paired through the OOB (OUT OF BAND) NFC method. And the Bluetooth unit can be used as the communication unit between the smart peripheral and the terminal to realize the purpose of using the smart peripheral as the input device (NFC power supply, Bluetooth communication) of the smart terminal.

In other embodiments, the communication component may also include infrared rays, WiFi, and other devices capable of communicating with mobile phones.

In the above embodiment, one or more of the communication component, MCU, rectifier circuit unit, voltage stabilizing unit, and input unit can be integrated in one SOC (that is, the above units are replaced by SOCs with the same function), or they can be separated or The combination is set in multiple different SOCs.

In this embodiment, the NFC unit itself can be used as a communication unit, and the smart peripheral performs data communication with the mobile phone through the NFC protocol; since the data transmitted by the NFC unit is usually NDEF and non-NDEF data, these data cannot be directly recognized by the game or APP. Control data (non-input), the received NFC data can be converted into input operation signals that can be recognized by the game or APP through the mobile phone, such as HID key values, touch (such as multi-touch) and other operation signals, such as input operation ticket signals Describe the input signals from HID devices such as game controllers, keyboards, touch devices, etc., convert NFC data into HID data format types and report to the above HID devices, which are processed by the mobile phone into the corresponding standard HID signal transmission application layer, such as Convert the data into a touch signal format that can be recognized by the smart terminal (such as: Android mobile phone, can be converted into Motionevent, coordinates and other formats, processed through the InputManager injectInputEvent, sendevent, monkey or Framework layer, and finally received at the application layer through OnTouchListener, onTouch Corresponding to the touch signal Motion Event).

In this embodiment, the smart peripheral can also use the OOB pairing method through the NFC unit and the Bluetooth of the mobile phone, and at the same time complete the power supply from the mobile phone to the smart peripheral, so that the mobile phone can be used without external power supply or built-in battery power supply.
