Description

Technical Field

[0001] This utility model relates to the field of adapter technology, and in particular to an adapter that can simultaneously connect to portable WIFI and power supply. Background Technology

[0002] A power adapter, also known as a converter plug, is a connector that allows one type of power plug to be used in another. It solves the problem of using electrical appliances from different countries in different countries, enabling power plug interoperability. Mobile Wi-Fi, through a built-in SIM card or an external mobile network, converts mobile network signals into Wi-Fi signals, allowing multiple devices to connect and use them. This provides great convenience for users who frequently travel for business or leisure, or who need to work remotely.

[0003] Currently, mobile Wi-Fi devices need to be plugged into the phone's charging port to transmit wireless signals. However, when a phone is plugged into a mobile Wi-Fi device for an extended period of time, the device consumes the phone's battery, which can easily lead to insufficient battery power. Since the phone's charging port is occupied by the mobile Wi-Fi device, it is impossible to charge the phone normally. Therefore, this application provides an adapter that can connect to both a portable Wi-Fi device and a power source simultaneously to meet this need. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide an adapter that can simultaneously connect to a portable Wi-Fi network and a power source. This addresses the issue where, when a mobile phone is plugged into a portable Wi-Fi network for extended periods, the phone's battery is depleted due to the Wi-Fi network consuming power, while the phone's charging port is occupied by the Wi-Fi network, preventing normal charging.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An adapter capable of simultaneously connecting to a portable Wi-Fi network and a power source includes an adapter body and a circuit structure disposed within the adapter body, the circuit structure comprising:

[0009] The signal conversion and communication circuit converts the protocol into a DPDM signal for the mobile phone. The mobile phone outputs 3.3V to power the signal conversion and communication circuit and allows the boost circuit to increase the voltage and current required by the external device. At the same time, it communicates and exchanges data with the WIFI device.

[0010] The boost circuit increases the voltage from 3.3V to 5V for high-voltage devices, while low-voltage devices do not require boosting and directly output 3.3V.

[0011] Optionally, the adapter body has a ⊥-shaped structure, and the adapter body is respectively equipped with a female charging head socket for connecting to a charger, a male charging head for connecting to a mobile phone, and a device port for connecting to a portable WIFI.

[0013] Optionally, the Data feeds back a 5V charging voltage to the charger, causing pin 5 of the charging head socket to output a Vin 5V voltage to the mobile phone.

[0014] Optionally, the male charging connector is provided with a charging communication pin (Data), an external device communication pin (DM / DP), a charging voltage input pin (Vin 5V), an OTG 3.3 voltage output pin (Vacc), a protocol signal pin (DP1 / DM1), and a ground pin (GND).

The USB signal of the Apple male connector's protocol signal pin (DP1 / DM1) is then given to the mobile phone, so that the mobile phone can output OTG 3.3V voltage normally when charging.

[0016] Optionally, a filter capacitor (C1) is connected to pin 1 of U1, a pull-up resistor (R3) is installed between pin 1 of U3 and pin 2 of U1, and a pull-down resistor (R4) and a pull-up resistor (R5) are connected to pins 3 and 5 of U3, respectively.

[0017] Optionally, the boost circuit includes a boost module (U4), the voltage of the charging male connector's voltage output pin (Vacc) passes through Q1 to U4 and L1, and the voltage of Vin passes through D2 to U4 and L1.

[0018] Optionally, C3 and R9 are filter circuits, and U4 and L1 are responsible for boosting the voltage, raising the voltage output pin (Vacc) and Vin to the values ​​required by the device, and then supplying it to the load device through D1, C4, R6, R7 and P1.

[0039] like Figures 1 to 8 As shown, an embodiment of this utility model provides an adapter that can simultaneously connect to a portable Wi-Fi network and a power source, including an adapter body 1 and a circuit structure disposed in the adapter body 1. The circuit structure includes:

[0040] The charging communication circuit detects that a charger is connected and outputs a signal to allow the phone to charge itself.

[0041] The male connector of the mobile phone outputs the charging current to the mobile phone, and at the same time transmits data and wireless network signals (4G / 5G) to the signal conversion and communication circuit.

[0042] The signal conversion and communication circuit converts the protocol into a DPDM signal for the mobile phone. The mobile phone outputs 3.3V to power the signal conversion and communication circuit and allows the boost circuit to increase the voltage and current required by the external device. At the same time, it communicates and exchanges data with the WIFI device.

[0043] The boost circuit increases the voltage from 3.3V to 5V for high-voltage devices, while low-voltage devices do not require boosting and directly output 3.3V.

[0044] The adapter body 1 has a ⊥-shaped structure, and the adapter body 1 is respectively equipped with a charging head female socket 2 for connecting to the charger, a charging male socket 3 for connecting to the mobile phone, and a device port 4 for connecting to portable WIFI. The charging head female socket 2 and the charging male socket 3 both include a Lightning interface and a Type-C interface. The charging communication circuit includes a charging communication chip (U2), Data (R1, R2) connected to pins 5 and 6 of the charging communication chip, and a filter capacitor connected to pin 4 of the charging communication chip. After the charging communication chip detects Data at the charger input pin 2, it sends a charging signal to the mobile phone connected to the charging male socket 3. Data feeds back a 5V charging voltage to the charger, so that pin 5 of the charging head female socket 2 outputs Vin 5V voltage to the mobile phone. The charging male socket 3 is provided with a charging communication pin (Data), an external device communication pin (DM / DP), a charging voltage input pin (Vin 5V), an OTG 3.3 voltage output pin (Vacc), a protocol signal pin (DP1 / DM1), and a ground pin (GND).

[0045] The signal conversion and communication circuit includes a protocol chip (U1) and a signal conversion chip (U3). Pins 2 / 6 of the protocol chip output an iiC signal to pin 1 / 2 of U3. U3 converts the iiC signal into a protocol signal pin (DP1 / DM1) signal and outputs it to the Apple male connector. The USB signal from the Apple male connector's protocol signal pin (DP1 / DM1) is then sent to the mobile phone, enabling the mobile phone to output OTG normally while charging. The circuit operates at 3.3V. Pin 1 of U1 is connected to a filter capacitor (C1). A pull-up resistor (R3) is installed between pin 1 of U3 and pin 2 of U1.

The signal conversion and communication protocol chip outputs the iiC signal through pin 2 / 6 to pin 1 / 2 of U3. U3 then converts it into a DP1 / DM1 signal and outputs it to the DP1 / DM1 USB signal of the male charging head 3, which is then sent to the phone, allowing the phone to output OTG 3.3V voltage normally during charging. The boost circuit boosts the Vacc and Vin voltages to the values ​​required by the device and provides them to the load device through D1, C4, R6, R7, and P1. When the charging communication circuit detects a charger input, it sends a charging signal to the phone connected to the male charging head 3 through pin 2 (Data). Data feeds back the 5V charging voltage to the charger. The charger outputs Vin 5V voltage to the mobile phone through pin 25 of the female connector. The built-in circuit of the adapter body 11 allows the wireless WIFI device to input a wireless signal to the charging mobile phone while the charger charges the mobile phone. This allows the mobile phone to use the wireless WIFI device while charging, improving the battery life and usability of the charging mobile phone when using the wireless WIFI device.
