[0002] The charging starting circuit, the charging gun and the charging pile having the charging starting circuit are key components for realizing the transmission of electric energy in the charging system of new energy equipment such as electric vehicles. In actual application, the charging process time using the charging gun and the charging pile is often long, and the user is likely to need to use the charged equipment again during the charging process, so there is a possibility of temporarily stopping charging. In the traditional case, the user often needs to pick up the mobile phone to operate the APP to stop charging, swipe the card to stop charging or set to stop charging in the charged equipment, and finally pull out the charging gun. The same steps need to be performed for recharging, which will consume a lot of time of the user, and when the user forgets to carry the mobile phone or charging card and the like, the charging and power-off operations will be more difficult, and the use is very inconvenient. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a charging starting circuit, a charging gun and a charging pile to solve at least one of the above technical problems in view of the above deficiencies in the prior art.

[0004] In a first aspect, a charging starting circuit is provided, comprising: a user verification module, a main control module, a signal transmission module for signal connection with an external device to be charged, a signal switch and a charging switch for controlling the on-off between the external device to be charged and a charging circuit; wherein the charging circuit refers to a circuit that can be directly connected with the external device to be charged and supply power to the external device to be charged.

[0005] The main control module is electrically connected with the user verification module, the signal switch and the charging switch respectively; and the signal switch is electrically connected with the signal transmission module.

[0006] The main control module is configured to send an opening signal or a closing signal to the signal switch and / or send a conduction signal or a shut-off signal to the charging switch when the verification pass signal sent by the user verification module is acquired.

[0007] By setting the user verification module in the charging starting circuit, the user of the charging can be quickly verified, which can improve the starting speed and efficiency of the charging starting circuit, and can also avoid intentional stopping of charging or electricity theft by others during the charging process, so as to ensure the safety and stability of the charging process.

[0008] In some embodiments, the signal transmission module includes a connection confirmation signal line and a charging pilot signal line; the connection confirmation signal line and the charging pilot signal line are connected to a signal switch; the connection confirmation signal line and the charging pilot signal line are used to connect to an external device to be charged. In actual application, the connection confirmation signal line is a CC signal line (Charging Connection Confirmation Signal Line, charging connection confirmation signal line) used to send a connection confirmation signal to the device to be charged, and the charging pilot signal line is a CP signal line (Control Pilot Signal Line, control pilot signal line) used to detect whether there is an abnormality between the device to be charged and the charging circuit, and send a pilot signal to the device to be charged to confirm that the charging process is normal. The main control module can control the conduction or shutdown between the external device to be charged and the charging circuit by turning on or off the connection of the connection confirmation signal line and the charging pilot signal line to the external device to be charged.

[0009] In actual application, the CC signal line and the CP signal line realize signal transmission by directly generating electrical connection with the external device to be charged during charging, so the voltage values in the CC signal line and the CP signal line are different when the CC signal line and the CP signal line generate electrical connection with the external device to be charged or do not generate electrical connection. In an embodiment, when the main control module is used to send a closing signal to the signal switch when the verification pass signal sent by the user verification module is obtained, the signal switch closes the connection between the CC signal line and the CP signal line and the external device to be charged. When the CP signal line is disconnected from the external device to be charged, its voltage value will jump from 6V or 9V to 12V. When the main control module recognizes the change in the voltage of the CP signal line, it sends a shutdown signal to the charging switch to disconnect the connection between the charging circuit and the external device to be charged in time.

[0010] In some embodiments, the signal switch includes a relay, and the relay is provided with a normally closed contact, and the connection confirmation signal line and / or the charging pilot signal line are connected to the normally closed contact; the relay is used to disconnect the normally closed contact to cut off the signal connection between the charging pilot signal line and the external device to be charged, and / or cut off the signal connection between the charging pilot signal line and the external device to be charged.

[0011] In actual application, by connecting the connection confirmation signal line and / or the charging pilot signal line to the normally closed contact, since the normally closed contact is in a normally closed state, the connection confirmation signal line and / or the charging pilot signal line can be turned on and continuously transmit signals under normal circumstances. After the user is verified by the user verification module, the main control module directly sends a conduction signal or a shutdown signal to the charging switch to conduct or shut off the connection between the external device to be charged and the charging circuit.

[0012] In some embodiments, the user authentication module comprises a fingerprint acquisition unit, a fingerprint storage unit and a fingerprint identification unit connected with each other; the fingerprint acquisition unit is configured to acquire fingerprint information from the outside world, the fingerprint storage unit is configured to store the fingerprint information, and the fingerprint identification unit is configured to identify the fingerprint information. In actual application, a user can input the fingerprint information into the fingerprint identification unit and the fingerprint storage unit by contacting a finger with the fingerprint acquisition unit, the fingerprint storage unit can acquire new authorized fingerprint information from the fingerprint acquisition unit and store the same, or the fingerprint storage unit can be pre-stored with authorized fingerprint information, and the fingerprint identification unit compares the fingerprint information in the fingerprint storage unit with the fingerprint information acquired by the fingerprint acquisition unit, thereby obtaining a verification pass signal or a verification fail signal, and sending the verification pass signal or the verification fail signal to the main control module.

The indication module can comprise an LED indicator, which can be one or more, and can have multiple colors, and can be used to indicate whether the user authentication module is running, and whether the main control module has acquired the verification pass signal sent by the user authentication module.

In addition to the fingerprint identification by the fingerprint identification unit, a user can complete the authentication and identification process in multiple ways, such as inputting a password through the touch screen for verification, palmprint identification verification, sound identification verification, and face recognition or iris recognition through the image recognition sensor for verification.

[0017] In a second aspect, a charging gun having any of the foregoing charging start-up circuits is provided. In one embodiment, the charging gun further includes a housing, wherein the master control module, the signal switch, the charging switch, the signal transmission module, and the internal power supply module of the charging start-up circuit are located within the housing, and a portion of the user verification module is exposed relative to the housing. In actual applications, when the user verification module includes a fingerprint acquisition unit, a fingerprint storage unit, and a fingerprint identification unit connected to each other, the fingerprint storage unit and the fingerprint identification unit are located within the housing, and the fingerprint acquisition unit is exposed relative to the housing, so that a user can directly touch the fingerprint acquisition unit with a finger to input fingerprint information into the fingerprint verification module.
