In some other embodiments, the identity data acquisition module 23 may be, for example, an NFC reader, for acquiring tag data TG from the user side and transmitting the tag data TG to the charging station 40 via the second set of transmission lines 32.

The first set of transmission lines 31 is electrically connected to the connector 22 and the charging station 40. The first set of transmission lines 31 may be used to transmit power PW from a charging station 40. The second set of transmission lines 32 is electrically connected to the display module 21 and the charging station 40. The second set of transmission lines 32 may be used to transmit the identity data IF or the tag data TG to the charging station 40. The first group of transmission lines 31 and the second group of transmission lines 32 may be wrapped inside the cable 30, and the cable has the characteristics of insulation, buffering, flame resistance, cold resistance, acid and alkali resistance, etc. Therefore, the first group of transmission lines 31 and the second group of transmission lines 32 can be protected from blocking moisture or reducing the problem of broken lines caused by external impact. In addition, when the user operates the charging gun 20, the whole aesthetic degree can be conveniently extracted and improved.

Referring to fig. 3, a schematic perspective view of a charging gun 20 with high operation efficiency according to an embodiment of the utility model is shown. Fig. 3 is a drawing with the side angle of the charging gun 20. The inside of the case 201 of the charging gun 20 includes a fixing hole 202, a portion of the release button 222, a portion of the hook 221, a spring 223, a portion of the display module 21, a circuit board 211, a connection terminal 212, a first group transmission line 31, and a second group transmission line 32. The exterior of the housing 201 of the charging gun 20 includes the connector 22, the interface terminal 220, the cable 30 and the protective sheath 301.

The fixing hole 202 may be locked by a screw (not shown). The release button 222 is located on the surface of the housing 201, and the identity data acquisition module 23 is disposed on the upper surface of the release button 222. The lower surface of the release button 222 is connected to one end of the spring 223, and the other end of the spring 223 is connected to one end of the hook 221. The other end of the hook 221 is exposed out of the housing 201 to be buckled with a hole on the charging stand, thereby completing the fixation of the charging gun 20 and the charging stand. The interface terminal 220 is electrically connected to the first set of transmission lines 31 to transmit the power PW from the charging station 40 to the charging stand of the electric vehicle 1 through the interface terminal 220, so as to charge the electric vehicle 1.

The identity data collection module 23 is electrically connected with the circuit board 211, and the circuit board 211 is electrically connected with the display module 21 and the connection terminal 212. The connection terminal 212 is electrically connected to the second set of transmission lines 32 to transmit the identity data IF collected by the identity data collection module 23 to the charging station 40. In addition, the second set of transmission lines 32 also transmit power from the charging station 40 to the display module 21 and the identity data collection module 23 to provide power required for the operation of the display module 21 and the identity data collection module 23. In the present embodiment, the identity data collection module 23 is located on the right side of the display module 21, and in other embodiments, the setting positions of the identity data collection module 23 and the display module 21 can be adjusted by changing the setting positions of the parts inside the housing 201, in other words, the setting positions of the identity data collection module 23 and the display module 21 are exchangeable or changeable.

As an example, how the charging gun 20 improves the operation convenience, reference is made to the schematic diagram of the relative positions shown in fig. 1. When the user 4 inserts the charging gun 20 on the charging stand of the electric vehicle 1, a finger can touch the surface of the identity data acquisition module 23 to transmit the identity data IF to the charging station 40, and the current progress of the charging procedure is known through the display module 21 on the charging gun 20. Then, the charging station 20 can determine whether it is an authorized user terminal according to the received identity data IF. When the authorized user terminal is confirmed, the charging station 40 starts the charging process until the electric vehicle 1 completes charging. In the process, the user 4 can issue an operation instruction to the charging station 40 through the menu screen presented by the display module 21, and view the current charging information and/or payment information at any time. Compared with the prior art, the charging gun 20 of the embodiment of the utility model can provide the user 4 with the capability of completing the starting or stopping of the charging procedure, the payment action, the checking of the charging information and/or the payment information in situ, without frequently going back and forth between the charging gun 20 and the charging station 40, and the time of going back and forth is saved. In particular, when the user 4 wants to stop charging and remove the charging gun 20, the release button 222 is pressed to drive the hook 221 to separate from the charging stand, and the surface of the identity data collection module 23 is touched while the release button 222 is pressed, so that the identity data IF of the user 4 is transmitted to the charging station 40 again to perform the related charging stopping procedure and/or payment procedure. Therefore, in addition to saving time for going to and from the charging gun 20 and the charging station 40, the process of stopping charging and the action of paying can be completed together, so that the whole operation is simpler and more convenient. In addition, if an unauthorized user (e.g., a user who does not start the charging procedure) touches the surface of the identity data collection module 23, the charging gun 20 and the charging stand can be locked by a locking mechanism (not shown) so as to avoid the problem that other users steal the charging gun 20 to charge other vehicles.

Referring to fig. 4, a top view of a charging gun 20 with high operation efficiency according to an embodiment of the utility model is shown. On the surface of the casing 201 of the charging gun 20, a release button 222 and a display module 21 are exposed, and the surface of the release button 222 is provided with an identity data acquisition module 23. In other embodiments, the identity data collection module 23 may be disposed at other locations, for example, opposite the location of the release button 222, and touch the surface of the identity data collection module 23 with a finger other than the thumb of the user 4 to obtain the identity data IF. In other embodiments, the identity data acquisition module 23 may also acquire the tag data TG in a contactless manner, for example, an NFC reader. Therefore, the identity data collection module 23 can be arranged at any position inside the shell 201, and can obtain the tag data TG in an inductive manner, and can also confirm whether the user 4 is an authorized user end, so that the design flexibility is improved. In addition, a protective sheath 301 is attached to the charging gun 20. The protecting sleeve 301 can be used to cover the connector 22 to protect the connector 22 and the interface terminal 220, thereby blocking moisture or reducing damage to the connector 22 caused by external impact, so as to prolong the service life of the charging gun 20. The protective sleeve 301 may be made of materials (such as rubber or silica gel) such as insulation, buffering, flame resistance, cold resistance, acid and alkali resistance, etc.

Referring to fig. 5A, a block diagram of a charging system 100 with high operation efficiency according to an embodiment of the utility model is shown. The charging system 100 includes a charging gun 20 and a charging station 40.

The charging station 40 may have basic functions for data calculation, analysis, and storage such as an operating system (e.g., windows, linux, unix, etc.), a control module 41, a power module 42, a charging module 43, a subscriber identification module 44, and a storage device (not shown). The control module 41 may be, for example, a central processing unit (central processing unit, CPU), or other programmable general purpose or special purpose micro control unit (micro control unit, MCU), application Specific Integrated Circuit (ASIC), graphics processor (graphics processing unit, GPU), image signal processor (IMAGE SIGNAL processor, ISP), image processing unit (image processing unit, IPU), microprocessor (microprocessor), digital signal processor (DIGITAL SIGNAL processor, DSP), programmable controller, field programmable gate array (field programmable GATE ARRAY, FPGA), or other similar element or combination of elements.

The power module 42 is electrically connected to the control module 41 and the cable 30. The power module 42 is configured to receive power from a power supply (not shown) and convert the power into power PW required for the electric vehicle 1 to perform a charging process, and then transmit the power PW to the connector 22 through the cable 30 according to a power transmission process. The power module 42 is controlled by the control module 41 to perform a power transmission procedure. The power transmission procedure refers to a procedure of starting or stopping transmission of the power PW to the electric vehicle 1 via the cable 30 (i.e., the first group of transmission lines 31), the path of the connector 22 by the power module 42 of the charging station 40. The control module 41 determines whether the power module 42 performs the power transmission process according to the start signal ST generated by the subscriber identity module 44. For example, when the start signal ST is at a high level voltage, the control module 41 causes the power module 42 to start the power transmission process. When the start signal ST is at a low level voltage, the control module 41 stops the power module 42 from performing the power transmission process. The power module 42 may be composed of, for example, a detection circuit, a control circuit, a communication circuit, an ac conversion circuit, a dc voltage conversion circuit, a signal isolation circuit, a rectifying circuit, an over-current protection circuit, and the like.

The charging module 43 is electrically connected to the control module 41, and calculates charging cost according to the time of the power module 42 performing the power transmission procedure. When the power module 42 starts or stops conducting the power transmission procedure, the billing module 43 is notified by the control module 41 to start or stop the timer, and the charge fee corresponding to the time of conducting the power transmission procedure is calculated. The charge rate information may be transmitted back to the control module 41 and displayed via the second set of transmission lines 32 to the display module 21 on the charging gun 20 for the user 4 to learn without moving to the charging station 40. Since the charge module 43 performs calculation based on the time when the power transmission process is started or stopped, rather than whether the electric vehicle 1 is pulled out of the charging gun 20, the problem of continuing to calculate the charge without pulling out the charging gun 20 after the completion of the charging is avoided. In addition, the billing module 43 may also communicate with a payment background (not shown) to complete the payment process.

The subscriber identity module 44 is electrically connected to the control module 41. The subscriber identity module 44 may be configured to generate the start signal ST based on the identity data IF or the tag data TG. The subscriber identification module 44 may store the identification data of the corresponding subscriber 4 in advance and compare the identification data IF or the tag data TG from the collected data 23 with the identification data. When the identity data IF or the tag data TG corresponds to the identification data, the user 4 can be confirmed as an authorized user. The pre-stored identification data may be retrieved using a user registration mechanism.

Referring to fig. 5B, a block diagram of a charging system 110 with high operation efficiency according to another embodiment of the utility model is shown. The charging system 110 includes a charging gun 20 and a charging station 401. The embodiment of fig. 5B differs from the embodiment of fig. 5A in that: the charging station 401 of fig. 5B is further provided with a second display module 45, and the other modules operate in a similar manner to the embodiment of fig. 5A, and are not described herein. The second display module 45 is electrically connected to the control module 41. The second display module 45 may be used to display charging information corresponding to the charging procedure and/or payment information including charging fees.

In summary, the charging gun 20 and the charging system 100 with high operation efficiency of the present utility model can enable the user to complete the start and stop of the charging process, check the charging and payment information and complete the payment action on site, and do not need to frequently go back and forth between the charging gun 20 and the charging station 40, which can save time and improve operation efficiency and convenience. Since the charging gun 20 is provided with the small-sized display module 21, the charging station 40 can be provided without a large-sized display screen, thereby reducing the construction cost of the charging station 40. In addition, when the user 4 pulls the charging gun 20 from the charging stand of the electric vehicle 1, the user can press the release button 222 and touch the identity data acquisition module 23 to complete the process of stopping charging and the payment process, so that the whole operation is simpler and more convenient.

The present utility model is not limited to the above embodiments, and various modifications may be made within the scope of the claims, and embodiments in which technical means disclosed in the different embodiments are appropriately combined are also included in the technical scope of the present utility model.
