Description

Technical Field

[0001] This application relates to the field of locking equipment technology, and more specifically, to locking devices and charging systems. Background Technology

[0002] The locking mechanism of known charging piles requires a matching charging plug to achieve reliable locking. However, some electrical equipment, such as ships, has charging plugs with various structural forms, making it impossible to achieve a reliable locking relationship with all shore-based charging piles. Furthermore, the large number and diverse types of ships make it difficult to require ship owners to standardize and modify their charging plugs.

[0003] Therefore, ensuring reliable locking between charging stations and different types of charging plugs is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a locking device and a charging system to solve the technical problem of how to ensure reliable locking between charging piles and different types of charging plugs.

[0005] This application provides a locking device for locking or unlocking a charging component to a charging pile, wherein the charging pile is provided with a charging socket. The locking device includes a driving component and a locking component. The driving component is used to connect to the charging pile. The locking component includes a first locking member and a second locking member. One end of the first locking member is tractively connected to the driving component, and the other end of the first locking member is a first free end. One end of the second locking member is tractively connected to the driving component, and the other end of the second locking member is a second free end. The second locking member and the first locking member are spaced apart along a first direction. The driving component is used to drive the locking component to move between a locked position and an unlocked position. When the locking component is in the locked position, the first free end is close to the charging pile, and the second free end is close to the charging pile. The first locking member and the second locking member clamp the charging component along the first direction, and limit the end of the charging component close to the charging pile to be between the locking component and the charging pile.

[0006] When the locking component is in the unlocked position, both the first free end and the second free end are away from the charging socket, and the locking component unlocks the charging component.

[0007] According to the locking device of this application, it can be installed on any charging pile, such as any charging pile at a port, via a driving component. The locking component can move between a locked position and an unlocked position under the action of the driving component, thereby locking any charging component onto the charging pile, exhibiting high versatility. Specifically, when the locking component is in the unlocked position, both the first and second free ends are away from the charging socket, so neither the first nor the second locking member obstructs the charging component, facilitating the user to insert or remove the charging component from the charging socket. After the charging component is inserted into the charging socket, the driving component can drive the locking component to the locked position, bringing the first and second free ends closer to the charging pile, thus preventing the charging component from disengaging from the gap between the first and second locking members and the charging pile. By clamping the charging component along a first direction with the first and second locking members, the charging component can be prevented from disengaging from the gap between the first and second locking members. In this way, it can be ensured that the charging component is locked onto the charging pile during charging.

[0008] In summary, the locking device of this application does not require modification of existing charging piles or charging components, thereby ensuring reliable locking between the charging pile and various types of charging components.

[0009] In one possible implementation:

[0010] The charging assembly includes a charging head and a cable. One end of the charging head is connected to a charging socket, and the other end of the charging head is connected to the cable. When the locking assembly is in the locked position, the first locking member and the second locking member clamp the cable along a first direction, and the locking assembly abuts against the charging head against the charging pile along a second direction, and limits the charging head along the extension direction of the locking assembly. The second direction is perpendicular to or intersects the first direction at an angle.

[0011] In one possible implementation:

[0012] The first locking member includes a first connecting segment, a first limiting segment, and a first cantilever. The first limiting segment is bent and connected to the first connecting segment, and the first cantilever is bent and connected to the first limiting segment. When the locking component is in the locked position, the first connecting segment and the first cantilever are correspondingly arranged and used to limit the charging component in a third direction.

[0013] In one possible implementation:

[0014] The second locking member includes a second connecting section, a second limiting section, and a second cantilever. The second limiting section is bent and connected to the second connecting section, and the second cantilever is bent and connected to the second limiting section. When the locking assembly is in the locked position, the second connecting section and the second cantilever are correspondingly arranged and used to limit the charging assembly in a third direction.

[0015] In one possible implementation:

[0016] The first locking member includes a locking rod and two limiting parts. The two limiting parts are connected to the locking rod at intervals along the length direction of the locking rod, and the two limiting parts extend toward the second locking member. When the locking member is in the locked position, the two limiting parts limit the charging member along the third direction.

[0017] In one possible implementation:

[0018] One end of the first locking member is movably connected to the driving assembly. The driving assembly is used to drive the first locking member to rotate about a first axis, and the driving assembly is also used to drive the first locking member to rotate about a second axis, so as to cause the first locking member to press the charging assembly against the second locking member in a first direction. The second axis is perpendicular to or intersects the first axis.

[0019] In one possible implementation:

[0020] One end of the second locking member is rotatably connected to the drive assembly, which drives the second locking member to rotate about a second axis parallel to the first direction.

[0021] In one possible implementation:

[0022] The locking device further includes a transmission assembly; the transmission assembly includes: a first transmission shaft, which is tractively connected to the drive assembly, the first transmission shaft extending along a first axis, one end of the first locking member being rotatably connected to one end of the first transmission shaft, and one end of the second locking member being fixedly connected to the other end of the first transmission shaft; a first transmission member, which is connected to the first transmission shaft; and a second transmission member, which is connected to the first locking member, the second transmission member engaging with the first transmission member to drive the first locking member to rotate around a second axis, the second axis being perpendicular to or intersecting the first axis at an angle.

[0023] In one possible implementation:

[0024] The driving assembly includes a first driving member and a second driving member; the locking device further includes a connecting shaft, the connecting shaft being drivenly connected to the first driving member, one end of the first locking member being rotatably connected to one end of the connecting shaft, one end of the second locking member being fixedly connected to the other end of the connecting shaft, the connecting shaft extending along a first axis; the second driving member being drivenly connected to the first locking member and used to drive the first locking member to rotate around a second axis, the second axis being perpendicular to or intersecting the first axis at an angle.

[0083] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0084] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0085] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0086] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0087] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0088] Shore power stations are charging stations installed on the shore. They provide power through shore power and offer charging services to ships in ports, parks, docks, and other locations. Shore power stations can be AC, DC, or AC / DC integrated.

[0089] Some electrical equipment, such as ships, has charging plugs with various structural forms, making it impossible to reliably lock them into place with all shore-based charging stations. Furthermore, the large number and diverse types of ships make it difficult to require ship owners to standardize their charging plugs. Therefore, in existing charging systems, users can freely plug and unplug charging components. This allows users to remove the charging components before the order is completed and the electricity bill is paid, leading to issues such as unauthorized electricity usage and fraudulent bill evasion. Simultaneously, the humid environment near water and the presence of salt spray in some areas increase the risk of electric shock due to indiscriminate plugging and unplugging, posing a significant safety hazard to electrical safety in production.

[0090] See Figure 1 This embodiment provides a charging system 400. The charging system 400 includes a charging pile 200 and a locking device 100. The charging pile 200 can specifically be a shore power pile 200a. This charging system 400 can be applied to port shore power systems, adding a locking function to known ship shore power piles 200a to prevent fare evasion and avoid users being blacklisted by maritime authorities for fare evasion; on the other hand, it also avoids losses for the terminal power supplier. Furthermore, it can further prevent abnormal situations such as missing order data caused by illegal plugging and unplugging of connectors and other charging components. In practical applications, it can be monitored manually or in an unattended mode.

[0091] Specifically, the locking device 100 involved in this embodiment can be an interactive locking device for connector safe insertion and removal to prevent escape of single-shore electric piles.

[0092] See Figures 1 to 3The locking device 100 is used to lock or unlock the charging assembly 300 to the charging pile 200. The charging pile 200 is provided with a charging socket 201. The locking device 100 includes a driving assembly 10 and a locking assembly 20. The driving assembly 10 is used to connect to the charging pile 200. The locking assembly 20 includes a first locking member 30 and a second locking member 40. One end of the first locking member 30 is tractively connected to the driving assembly 10, and the other end of the first locking member 30 is a first free end 30a; the other end of the second locking member 40 is a second free end 40a. The second locking member 40 and the first locking member 30 are spaced apart along a first direction X. The driving assembly 10 is used to drive the locking assembly 20 to move between a locked position and an unlocked position. When the locking assembly 20 is in the locked position, the first free end 30a and the second free end 40a are close to the charging pile 200. The first locking member 30 and the second locking member 40 clamp the charging assembly 300 along the first direction X, and limit the end of the charging assembly 300 near the charging pile 200 to be between the locking assembly 20 and the charging pile 200. When the locking assembly 20 is in the unlocked position, both the first free end 30a and the second free end 40a are away from the charging socket 201, and the locking assembly 20 unlocks the charging assembly 300.

[0093] The locking device 100 according to this embodiment can be installed on any charging pile 200, such as any charging pile 200 at a riverbank, via the drive assembly 10. The locking assembly 20 can move between a locked position and an unlocked position under the actuation of the drive assembly 10, thereby locking any charging component 300 onto the charging pile 200, exhibiting high versatility. Specifically, see... Figure 1 When the locking component 20 is in the unlocked position, both the first free end 30a and the second free end 40a are away from the charging socket 201, so neither the first locking member 30 nor the second locking member 40 will obstruct the charging component 300, allowing the user to insert or remove the charging component 300 from the charging socket 201. See also Figure 2 After the charging component 300 is inserted into the charging socket 201, the driving component 10 can drive the locking component 20 to move to the locking position. The first free end 30a and the second free end 40a approach the charging pile 200, preventing the charging component 300 from disengaging from the gap between the first locking member 30 and the charging pile 200, and the gap between the second locking member 40 and the charging pile 200. By clamping the charging component 300 along the first direction X with the first locking member 30 and the second locking member 40, the charging component 300 is prevented from disengaging from the gap between the first locking member 30 and the second locking member 40. In this way, it can be ensured that the charging component 300 is locked to the charging pile 200 during charging.

[0094] In summary, the locking device 100 of this application does not require modification of the existing charging pile 200 or charging component 300, thereby ensuring reliable locking between the charging pile 200 and various types of charging components 300.

[0095] Meanwhile, the locking device 100 in this embodiment can prevent users from arbitrarily plugging and unplugging the charging component 300, reducing the risk of electric shock accidents and improving the safety of electricity use in production. Furthermore, the locking device 100 can be configured to unlock the locking component 20 after the user completes the payment, thereby avoiding data loss due to plugging and unplugging the charging component 300 before the order is completed, reducing malicious evasion of payment due to plugging and unplugging the charging component 300 before order payment is completed, and reducing abnormal vessel information caused by directly plugging in the charging component 300 to draw power when changing vessels without passing the identity authentication lock.

[0096] It should be noted that when the locking assembly 20 is in the locked position, the first locking member 30 and the second locking member 40 can have multiple positions. For example, the first free end 30a of the first locking member 30 is close to the charging pile 200, and the second free end 40a of the second locking member 40 is away from the charging pile 200. In this case, the user can remove the charging assembly 300 by moving it in the first direction X away from the first locking member 30. Another example is that the first free end 30a is away from the charging pile 200, and the second free end 40a is close to the charging pile 200. In this case, the user can remove the charging assembly 300 by moving it in the first direction X away from the second locking member 40. Yet another example is that both the first free end 30a and the second free end 40a are away from the charging pile 200. In this case, the user can directly remove the charging assembly 300.

[0097] Therefore, there are various forms of locking position for the locking component 20, and this embodiment does not specifically limit them.

[0098] In some embodiments, see Figure 2 The locking device 100 also includes a mounting housing 80. A drive assembly 10 is disposed within the mounting housing 80 and is connected to the mounting housing 80. The mounting housing 80 is used for installation on the charging pile 200. This facilitates the connection between the locking device 100 and the charging pile 200, and the mounting housing 80 also provides good protection for the drive assembly 10.

[0099] In some embodiments, see Figure 1 and Figure 2The charging assembly 300 includes a charging head 301 and a cable 302. One end of the charging head 301 is connected to the charging socket 201, and the other end of the charging head 301 is connected to the cable 302. When the locking assembly 20 is in the locked position, the first locking member 30 and the second locking member 40 clamp the cable 302 along the first direction X, and the locking assembly 20 abuts against the charging head 301 against the charging pile 200 along the second direction Y, and limits the charging head 301 along the extension direction of the locking assembly 20; the second direction Y is perpendicular to or intersects the first direction X at an angle.

[0100] Specifically, in this embodiment, the extending direction of the locking component 20 is from the charging socket 201 along the third direction Z, past the charging socket 201, to the other side of the charging socket 201 along the third direction Z. This allows the charging head 301 to be limited along the third direction Z by the locking component 20. Simultaneously, in conjunction with the locking component 20 limiting the charging head 301 along the second direction Y and clamping the cable 302 along the first direction X, the locking component 20 completely restricts all six degrees of freedom of the charging component 300, ensuring a reliable locking effect on the charging component 300.

[0101] In some embodiments, see Figure 1 and Figure 2 The charging pile 200 has a first side P1, a second side P2, and a third side P3. The second side P2 and the third side P3 are respectively connected to the two sides of the first side P1. The charging socket 201 is disposed on the first side P1. The mounting shell 80 is fixed to the second side P2.

[0102] In some embodiments, the first locking member 30 includes a first connecting segment 31, a first limiting segment 32, and a first cantilever 33. The first limiting segment 32 is bent and connected to the first connecting segment 31, and the first cantilever 33 is bent and connected to the first limiting segment 32. When the locking assembly 20 is in the locked position, the first connecting segment 31 and the first cantilever 33 are correspondingly disposed and used to limit the charging assembly 300 along a third direction Z. The end of the first cantilever 33 opposite to the first connecting segment 31 forms a first free end 30a. The first limiting segment 32 and the second locking member 40 limit the charging assembly 300 along a first direction X.

[0103] Thus, by limiting the charging component 300 along the third direction Z by the first connecting segment 31 and the first cantilever 33, the limiting effect on the charging component 300 can be further improved, thereby reducing the possibility that the charging component 300 may come out of the gap between the first locking member 30 and the charging pile 200 along the second direction Y.

[0104] Optionally, the first connecting segment 31 extends from the second side P2 along the second direction Y. When the locking assembly 20 is in the locked position, the distance between the first cantilever 33 and the first side P1 is less than the dimension of the charging head 301 along the second direction Y to ensure a limiting effect. For example, the first cantilever 33 may be spaced apart from the first side P1 along the second direction Y. The first cantilever 33 may abut against the first side P1. The first cantilever 33 may also extend along the second direction Y to the third side P3.

[0105] In some embodiments, the second locking member 40 includes a second connecting segment 41, a second limiting segment 42, and a second cantilever 43. The second limiting segment 42 is bent and connected to the second connecting segment 41, and the second cantilever 43 is bent and connected to the second limiting segment 42. When the locking assembly 20 is in the locked position, the second connecting segment 41 and the second cantilever 43 are correspondingly disposed and used to limit the charging assembly 300 along a third direction Z. The second limiting segment 42 and the first locking member 30 limit the charging assembly 300 along a first direction X.

[0106] Thus, by limiting the charging component 300 along the third direction Z through the second connecting section 41 and the second cantilever 43, the limiting effect on the charging component 300 can be further improved, thereby reducing the possibility that the charging component 300 may come out of the gap between the first locking member 30 and the charging pile 200 along the second direction Y.

[0107] Optionally, the second connecting segment 41 extends from the second side P2 along the second direction Y. When the locking assembly 20 is in the locked position, the distance between the second cantilever 43 and the first side P1 is less than the dimension of the charging head 301 along the second direction Y to ensure a limiting effect. For example, the second cantilever 43 may be spaced apart from the first side P1 along the second direction Y. The second cantilever 43 may abut against the first side P1. The second cantilever 43 may also extend along the second direction Y to the third side P3.

[0108] In other embodiments, the mounting housing 80 may also be fixed to the first side P1 or the third side P3. The fixed position of the mounting housing 80 may be adjusted according to the specific structure of the first locking member 30 and the second locking member 40, and this embodiment does not impose a specific limitation on it.

[0109] In some embodiments, see Figure 3 The first locking member 30 includes a locking rod 34 and two limiting portions 35. The two limiting portions 35 are spaced apart from the locking rod 34 along its length and extend towards the second locking member 40 along a first direction X. When the locking assembly 20 is in the locked position, the two limiting portions 35 limit the charging assembly 300 along a third direction Z. This further improves the locking reliability of the charging assembly 300.

[0110] Specifically, the locking lever 34 includes a first connecting section 31, a first limiting section 32, and a first cantilever 33. A limiting part 35 is provided at the connection between the first connecting section 31 and the first limiting section 32. Another limiting part 35 is provided at the connection between the first connecting section 31 and the first cantilever 33.

[0111] In other embodiments, the specific structure of the first locking member 30 can be similar to that of the first locking member 30, thereby further improving the limiting effect.

[0112] In some embodiments, one end of the first locking member 30 is movably connected to the driving assembly 10. The driving assembly 10 is used to drive the first locking member 30 to rotate about the first axis L1, and the driving assembly 10 is also used to drive the first locking member 30 to rotate about the second axis L2, so as to cause the first locking member 30 to press against the charging assembly 300 against the second locking member 40 along the first direction X. The second axis L2 is perpendicular to or intersects the first axis L1. Wherein, when the locking assembly 20 is in the locked position, the first axis L1 is parallel to the first direction X, and the second axis L2 is parallel to the third direction Z.

[0113] Thus, after the first locking member 30 is driven by the driving component 10 to press against the charging component 300 in the first direction X, the driving component 10 itself has a self-locking function, which can avoid the possibility of the operator unlocking the locking component 20 by himself, thereby ensuring the reliability of locking.

[0114] The drive component 10 can be constructed as a drive component such as a motor.

[0115] In some embodiments, one end of the second locking member 40 is rotatably connected to the driving assembly 10, which drives the second locking member 40 to rotate about a second axis L2, which is parallel to the first direction X. Thus, as the locking assembly 20 moves from the locked position to the unlocked position, the second free end 40a moves away from the charging socket 201, providing more degrees of freedom for the charging assembly 300, allowing users to more easily install and remove the charging assembly 300, thus improving the user experience. In other embodiments, the second locking member 40 can also be fixedly installed on the charging pile 200. For example, both ends of the second locking member 40 can be fixedly connected to the edges of the first side P1; or, both ends of the second locking member 40 can be fixedly connected to the second side P2 and the third side P3 respectively; or, the second locking member 40 can be directly fixedly connected to the mounting housing 80.

[0116] In some embodiments, see Figure 4The locking device 100 further includes a transmission assembly 50. The transmission assembly 50 includes a first transmission shaft 51, a first transmission member 52, and a second transmission member 53. The first transmission shaft 51 is driveably connected to the drive assembly 10 and extends along a first axis L1. One end of a first locking member 30 is rotatably connected to one end of the first transmission shaft 51, and one end of a second locking member 40 is fixedly connected to the other end of the first transmission shaft 51. The first transmission member 52 is driveably connected to the first transmission shaft 51. The second transmission member 53 is connected to the first locking member 30, and the second transmission member 53 and the first transmission member 52 are in a driving cooperation to drive the first locking member 30 to rotate around a second axis L2. The second axis L2 is perpendicular to or intersects the first axis L1 at an angle. The first axis L1 may be parallel to a first direction X. The second axis L2 may be parallel to a second direction Y.

[0117] Thus, by using a single drive structure in conjunction with the transmission component 50, the switching efficiency of the locking component 20 between the locked and unlocked positions can be improved.

[0118] Optionally, both the first transmission member 52 and the second transmission member 53 can be constructed as transmission components such as transmission gears, transmission wheels, or transmission sprockets.

[0119] In some embodiments, the first transmission member 52 includes a first transmission portion 521, a second transmission portion 522, a second transmission shaft 524, and a third transmission portion 523. The first transmission portion 521 is driveably connected to the first transmission shaft 51. The second transmission portion 522 and the third transmission portion 523 are respectively connected to the two ends of the second transmission shaft 524. The second transmission shaft 524 extends along a second axis L2. The second transmission portion 522 is driveably engaged with the first transmission portion 521. The third transmission portion 523 is driveably engaged with the second transmission member 53.

[0120] The first transmission unit 521 and the second transmission unit 522 can be constructed as helical gears to adjust the transmission direction from the first direction X to the second direction Y.

[0121] In some embodiments, the locking device 100 further includes a first output shaft 71. The first output shaft 71 is driveably connected to the drive assembly 10. The first output shaft 71 extends along a first axis L1. The first output shaft 71 is parallel to and spaced apart from the first drive shaft 51. The drive assembly 50 further includes a fourth drive section 54 and a fifth drive section 55. The fourth drive section 54 is connected to the first output shaft 71. The fifth drive section 55 is connected to the first drive shaft 51. The fourth drive section 54 and the fifth drive section 55 are in drive engagement. The third drive section 523, the third drive member 62, the fourth drive section 54, and the second drive section 522 can all be constructed as transmission components such as gears, sprockets, or synchronous pulleys.

[0122] In this embodiment, the first transmission part 521 can be fixedly connected to the first output shaft 71, thereby realizing transmission cooperation with the first transmission shaft 51. In other embodiments, the first transmission part 521 can also be fixedly connected to the first transmission shaft 51, and the first transmission part 521 is staggered from the first locking member 30.

[0123] Figure 5 A schematic diagram of the structure of a locking device 100 according to another embodiment of this application is shown.

[0124] See Figure 5 The drive assembly 10 includes a first drive member 11 and a second drive member 12. The locking device 100 also includes a connecting shaft 61. The connecting shaft 61 is driveably connected to the first drive member 11. One end of the first locking member 30 is rotatably connected to one end of the connecting shaft 61. One end of the second locking member 40 is fixedly connected to the other end of the connecting shaft 61. The connecting shaft 61 extends along a first axis L1. The second drive member 12 is driveably connected to the first locking member 30 and is used to drive the first locking member 30 to rotate about a second axis L2. The second axis L2 intersects the first axis L1 perpendicularly or at an angle.

[0125] This improves the movement accuracy of the locking component 20 between the locked and unlocked positions, and reduces the possibility of the first locking component 30 damaging the charging component 300.

[0126] Both the first driving component 11 and the second driving component 12 can be constructed as motors.

[0127] Optionally, the locking device 100 further includes a first output shaft 71, a third transmission member 62, and a fourth transmission member 63. The first output shaft 71 is driveably connected to the first driving member 11. The first output shaft 71 and the connecting shaft 61 are radially spaced apart. The third transmission member 62 is connected to the first output shaft 71. The fourth transmission member 63 is connected to the connecting shaft 61. The third transmission member 62 and the fourth transmission member 63 are in a driving engagement. In this way, speed variation can be achieved.

[0128] The third transmission component 62 and the fourth transmission component 63 can be connected by gears, sprockets or synchronous pulleys.

[0129] Optionally, the locking device 100 further includes a second output shaft 72, a fifth transmission member 64, and a sixth transmission member 65. The second output shaft 72 is radially spaced from the first locking member 30. The second output shaft 72 is driveably connected to the second driving member 12. The fifth transmission member 64 is connected to the second output shaft 72. The sixth transmission member 65 is connected to the first locking member 30. The fifth transmission member 64 and the sixth transmission member 65 are in a driving engagement. The fifth transmission member 64 and the sixth transmission member 65 can be driven by gears, sprockets, or synchronous pulleys.

[0130] In other embodiments, the locking assembly 20 also has other forms of movement. For example, the first locking member 30 is rotatable about a third axis. The second locking member 40 is rotatable about a third axis. During the movement of the locking assembly 20 from the locked position to the unlocked position, the first limiting segment 32 of the first locking member 30 moves away from the charging socket 201 along the first direction X, and the second limiting segment 42 of the second locking member 40 moves away from the charging socket 201 along the first direction X, thereby releasing the restriction on the charging assembly 300 along the first direction X. Furthermore, the distance between the first cantilever 33 of the first locking member 30 and the second cantilever 43 of the second locking member 40 along the first direction X increases, thereby releasing the restriction on the charging assembly 300 along the second direction Y and the third direction Z.

[0131] Therefore, there are various specific driving methods for the locking component 20, and the embodiments of this application only illustrate some of the implementation methods.

[0132] The following describes an exemplary application scenario of the charging system 400 of this embodiment. This description is merely illustrative of the application of the charging system 400, and the charging system 400 of this embodiment is not limited to this application scenario.

[0133] Users can register by scanning a code on the shore power station 200a or input control information using the corresponding application to send an unlocking command to the control module of the locking device 100. The control module can be a PLC controller, etc. After receiving the unlocking command, the control module controls the locking device 100 to move to the unlocked position.

[0134] The user inserts the charging component 300 into the charging socket 201. After receiving the signal that the charging component 300 has been inserted, the control module controls the locking device 100 to move to the locking position, controls the shore power pile 200a to operate, and performs billing.

[0135] After charging is complete, the user can send a stop charging signal to the control module through interface interaction, application operation, or QR code scanning. The control module then controls the shore power pile 200a to stop supplying power. The control module compares the collected power consumption data with the actual power consumption data. If the data meets the requirements, the control module then controls the locking device 100 to move to the unlocked position so that the user can remove the charging component 300.

[0136] After the user removes the charging component 300, the control module then controls the locking device 100 to move to the unlocked position.

[0137] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
