[0002] In order to ensure the safety of people's lives and property, the state prohibits the charging of electric bicycles in residential and commercial buildings. In this case, in order to facilitate the charging of electric bicycles, each community is equipped with paid charging piles to facilitate people's charging and use.

[0003] Most existing charging piles use IC cards or scan QR codes to read user information for billing. However, using IC cards to read user information is convenient and fast, but it requires users to carry IC cards with them in case of emergency. Most IC cards are anonymous and have no password. If they are lost, they need to go to the card issuing office to report the loss, which is very inconvenient. Scanning QR codes to read user information requires opening an APP on a mobile phone, completing the QR code scanning, selecting the corresponding service, and other steps before charging. It usually takes three to five minutes to operate. In the summer when there are many mosquitoes, mosquitoes will bite in three to five minutes. In the cold winter, users are also unwilling to expose their hands to operate the mobile phone to scan the QR code for charging.

[0004] Therefore, how to quickly and conveniently use charging piles to charge electric bicycles is a technical problem we need to solve. Utility Model Content

[0031] The following combination Figures 1 to 4 , the structure of the charging identification kit that is convenient to use in this application is explained.

[0032] The present embodiment relates to a plug 10, which is equipped with a memory chip 11 for storing information and a first induction coil 12 for transmitting signals. The plug 10 is provided with a plug pin 14 for charging. When the plug pin 14 is inserted into a socket 20, the first induction coil 12 is coupled to a radio frequency reader 21 in the socket 20, so that the radio frequency reader 20 reads the information in the memory chip 11.

[0033] The plug of this embodiment integrates the first induction coil 12 and the memory chip 11 on the plug 10. When the plug 10 is fixed on the socket 20 through the pins 14, the first induction coil 12 can be coupled with the radio frequency reader 21, so that the radio frequency reader 21 reads the information in the memory chip 11, thereby modulating and decoding the information signal in the memory chip 11, and sending the decoded processed information to the control device described below, and the circuit is connected through the control device.

[0034] Preferably, the memory chip 11 is installed inside the plug 10, and the first induction coil 12 is arranged near the pin 14. Furthermore, a card slot 13 for accommodating the memory chip 11 is provided inside the plug 10, and the memory chip 11 is installed in the card slot 13.

[0035] Furthermore, the first induction coil 12 is disposed around one or more pins 14 of the plug 10. By disposing the first induction coil 12 around the pins 14, the layout area of ​​the first induction coil 12 can be increased, the coupling effect can be improved, and the first induction coil 12 can be close to the pins 14, so that when the plug 10 is inserted into the socket 20, the distance between the first induction coil 12 and the socket 20 can be shortened, further ensuring the coupling effect.

[0036] The present embodiment also relates to a socket, on which a radio frequency reader 21 for reading information in a memory chip 11 is mounted, the radio frequency reader 21 comprising a second induction coil 211 for transmitting a signal, the second induction coil 211 being mounted on the socket 20 near a socket 25. The radio frequency reader 21 of the present embodiment adopts a prior art structure, which will not be described in detail herein.

[0037] Furthermore, the second induction coil 211 is arranged around one or more jacks 25. By arranging the second induction coil 211 in this way, the coupling effect between the first induction coil 12 and the second induction coil 211 can be further ensured, the charging effect of the socket 20 and the plug 10 can be ensured, and signal obstruction can be avoided.

[0038] In addition, the present embodiment also relates to a plug-and-charge charging device provided with the above-mentioned plug 10 and socket 20 , and the charging device also includes a control device for controlling the on-off of the circuit in the socket 20 , and the control device is electrically connected to the radio frequency reader 21 .

[0039] This embodiment provides a plug-and-charge charging device, in which a user information chip is installed inside the plug 10. When the plug 10 is plugged into the socket 20, the radio frequency reader 21 installed in the socket 20 reads the information and triggers the circuit for charging.

[0040] Specifically, the control device can be installed inside the socket 20 and electrically connected to the RF reader 21 in the socket 20, or the control device can be installed outside the socket 20 and electrically connected to the RF readers 21 of multiple sockets 20. In this way, one control device can control multiple sockets 20 simultaneously.

[0041] In one embodiment, the control device includes a driving circuit board 24 for controlling the power supply of the socket 20, a contactor 23 for triggering the circuit on and off of the driving circuit board 24, and a controller 22 for controlling the switch of the contactor 23. The radio frequency reader 21 and the contactor 23 are electrically connected to the controller 22 through a wired line, and the contactor 23 is electrically connected to the driving circuit board 24 through a wired circuit. After the driving circuit board 24 is triggered, the circuit remains in an on state, thereby continuously supplying power to the output voltage.

[0042] In one embodiment, the control device is also electrically connected to a wireless networking device 26 , and the control device is wirelessly connected to an external main server 30 via the wireless networking device 26 .

[0043] The specific process is as follows: the radio frequency reader 21 reads the user account information in the storage chip 11 and sends the information to the control device, and the control device transmits the information to the external main server 30 through a wireless network signal. The external main server 30 can form corresponding instructions based on the chip information sent by the control device and the information in the database of the external main server 30 through the control strategy used in the prior art and send them to the control device. The control device controls the contactor 23 to trigger the driving circuit board 24 according to the received instructions. After the driving circuit board 24 is turned on by the trigger circuit, the circuit remains in the on state, thereby continuously supplying power to the output voltage.

[0044] After charging is completed, the power can be turned off manually or automatically through a control instruction sent to the controller 22 by the external main server 30.

[0045] The beneficial effects of the utility model include: it can be applied to charging parking spaces in residential areas and charging electric bicycles, and is particularly suitable for charging electric bicycles, and can avoid private wiring, and is convenient, fast and safe.
