Description

Technical Field

[0001] The present disclosure relates to a trigger structure for a circuit, an electronic lock, and a socket assembly, and in particular to a trigger structure for a circuit, an electronic lock, and a socket assembly that serve as a position detection device, for example in the technical field of new energy vehicle charging equipment. Background Art

[0002] Conventional fuel-powered vehicles emit large amounts of pollutants, contributing to a significant increase in air pollution. To protect the environment and reduce air pollution, the automotive industry is currently focusing on developing new energy vehicles, primarily electric vehicles, as these vehicles directly utilize electricity and emit no pollutants. To facilitate charging, electric vehicles are currently equipped with a charging station that mates with a charging gun to charge the onboard battery. These stations are typically charged using a charging station equipped with a charging plug (also known as a charging gun). To charge, the plug is plugged directly into the vehicle's charging socket.

[0003] For example, according to national standards, when charging an electric vehicle, in order to prevent the charging gun from accidentally separating from the charging socket during charging and ensure safety during charging, the charging plug must be reliably locked to the charging socket of the electric vehicle during the charging process and cannot be unplugged from the charging socket of the electric vehicle.

[0004] In the prior art, charging plugs are typically equipped with an electronic lock, comprising a mechanical latch structure and a drive device. The drive device, for example, is a motor operating under the control of an electronic lock circuit triggered by a trigger structure (which acts as a position detection device), and is controlled to actuate the mechanical latch structure. During charging, the mechanical latch structure on the charging plug is locked to the charging socket on the electric vehicle. The electronic lock circuit in the charging plug is triggered to actuate and maintain the mechanical latch structure in the locked position to prevent the mechanical lock from being accidentally unlocked from the locked state, and to reset the mechanical latch structure to a retracted state.

[0005] Typically, in the prior art, the mechanical latch structure of the electronic lock usually includes a movable part, a locking pin fixed to the movable part, and a pull rope connected to the movable part. When the movable part moves to the locked position, the position detection device detects that the movable part is in the locked position, thereby triggering the circuit to control the motor to drive the locking pin forward to engage with the pin hole on the charging gun inserted into the charging base, thereby preventing the charging gun from being pulled out of the charging base. When the movable part moves to the unlocked position, the position detection device detects that the movable part is in the unlocked position, thereby triggering the circuit to control the motor to drive the locking pin backward to separate from the pin hole on the charging gun inserted into the charging base, thereby allowing the charging gun to be pulled out of the charging base. In addition, when the electronic lock malfunctions and cannot automatically drive the movable part from the locked position to the unlocked position, the movable part can be reset to the unlocked position by pulling the pull rope, thereby achieving manual unlocking.

[0006] In the prior art, to accurately determine the position of an electronic lock's movable element, two microswitches operating in opposite directions are typically installed in the lock's housing to serve as triggers, or position detection devices. When the movable element moves to the locked position, one of the two microswitches is pressed downward by the movable element, thereby energizing the first position detection subcircuit and disconnecting the second. When the movable element moves to the unlocked position, the other of the two microswitches is pressed downward by the movable element, thereby energizing the second position detection subcircuit and disconnecting the first. This allows the real-time position of the movable element to be detected. However, the use of two microswitches results in high costs and a larger size, which increases the cost and size of the electronic lock. Furthermore, the use of two microswitches reduces the robustness and reliability of the overall system. Furthermore, in some applications, the shape and size of the installation space prohibit the presence of excessive redundant components, which limits the use of more than one (e.g., two) microswitches as circuit triggers in electronic locks.

[0007] In the prior art, there is an urgent need for an improved electronic lock circuit trigger structure, which is, for example, in the form of a single piece with a simple structure to replace the conventional micro switch, thereby reducing the size, enhancing the robustness and reliability of the overall mechanical-electrical contact structure, and reducing costs; and it is required to be improved in terms of load capacity relative to the micro switch. Utility Model Content

[0008] The purpose of the present disclosure is to solve at least one aspect of the above-mentioned problems and defects in the prior art by providing a trigger structure for a circuit, an electronic lock, and a socket assembly that have a simple structure, high robustness of mechanical and electrical contact, and are in a single-piece form.

[0009] To achieve the above objectives, the present disclosure is implemented through the following technical solutions:

[0010] In a first aspect of the present disclosure, a trigger structure for a circuit of an electronic lock is provided, comprising: a conductive connector electrically connected to the circuit and comprising a plurality of conductive pads and a plurality of conductive traces electrically connected to the plurality of conductive pads; and a conductive spring.

[0017] In an exemplary embodiment, in the second state in which one of the pair of wings is subjected to a pressing force toward the fixing portion, the pair of wings pivots about the cantilever portion so that the corresponding conductive contact portion of the one wing is pushed toward the corresponding conductive pad and is in conductive contact, and the corresponding conductive contact portion of the other wing is simultaneously shifted away from the corresponding conductive pad and disconnected.

[0018] In an exemplary embodiment, when the pressing force stops, the pair of wings pivot about the cantilever portion and return to the first state.

[0019] In an exemplary embodiment, the fixing portion includes a grounded conductive contact on a bottom surface facing away from the pair of wings.

[0020] In a second aspect, the present disclosure provides an electronic lock, comprising: a housing; according to the aforementioned trigger structure, the conductive connector and the fixed portion of the conductive spring are fixedly mounted in the housing; a moving member, movably mounted in the housing and configured to move between a locked position and an unlocked position; and a locking pin, fixed in the housing and extending to the outside of the housing through a pin hole on the housing. When the moving member is moved to the locked position, one of the pair of wings is pressed by the moving seat so as to at least partially come into conductive contact with the corresponding conductive pad facing it, and the other wing is moved away from the corresponding conductive pad facing it; when the moving member is moved to the unlocked position, the other wing of the pair of wings is pressed by the moving seat so as to at least partially come into conductive contact with the corresponding conductive pad facing it, and the one wing is moved away from the corresponding conductive pad facing it.

[0037] FIG1 is a schematic diagram illustrating a trigger structure for a circuit according to an embodiment, wherein Figure 1(a) to Figure 1(g) It is shown in schematic stereogram, front view, rear view, left view, right view, top view and bottom view respectively; and Figure 1(h) and Figure 1(i) respectively show the stereogram of the conductive spring in the trigger structure in the initial unstressed state from different perspectives.

[0038] According to an overall technical concept of the present disclosure, for example, as shown in Figure 1, a trigger structure 10 for a circuit for an electronic lock suitable for the field of electric vehicle charging is provided, including: a conductive connector 101, which is conductively connected to the circuit and includes a plurality of conductive pads 30 (for example, a common ground conductive pad PIN3, a left conductive pad PIN4, and a right conductive pad PIN5 as shown in the figure) and a plurality of conductive traces 40 that are conductively connected to the plurality of conductive pads 30; and a conductive spring 102. In an exemplary embodiment, as shown in the figure, the conductive spring 102 includes, for example: a fixed portion 103, a portion of which is grounded; a pair of wings 104, extending longitudinally along the fixed portion 103, the fixed portion 103 is connected between the pair of wings 104, one of the pair of wings 104 is configured to be at least partially in conductive contact with the corresponding conductive pad 30 under the action of a pressing force and the other is configured to be disconnected from the corresponding conductive pad 30 at the same time; and a cantilever portion 105, connected between the pair of wings 104, the pair of wings 104 are connected to the fixed portion 103 via the cantilever portion 105.

[0039] Through this arrangement, a "seesaw" structure is achieved in the conductive spring clip 102, in which the pair of wings 104 can pivot around the cantilever portion 105 between them, moving toward and away from the corresponding conductive pad 30 they face. When a pressing force acts on one of the pair of wings 104, the one wing 104 moves toward the corresponding conductive pad 30 it faces under the action of the pressing force, so as to at least partially form a conductive contact with the corresponding conductive pad 30, and at the same time, the other wing 104 moves away from the corresponding conductive pad 30 it faces and remains disconnected from the conductive pad 30, thereby triggering the circuit where the conductive pad 30 in conductive contact with the one wing 104 is located, and keeping the circuit where the conductive pad 30 disconnected from the other wing 104 is located open. Vice versa, when a pressing force acts on the other wing 104 of the pair of wings 104, the other wing 104 moves toward the corresponding conductive pad 30 it faces under the pressure, at least partially forming conductive contact with the corresponding conductive pad 30, while the one wing 104 simultaneously moves away from the corresponding conductive pad 30 it faces, remaining disconnected from the conductive pad 30. This achieves triggering of the circuit containing the conductive pad 30 in conductive contact with the other wing 104, and maintains disconnection of the circuit containing the conductive pad 30 disconnected from the one wing 104. Thus, by using only this simple, single-piece trigger structure 10 to replace conventional dual microswitch triggering devices, reliable bidirectional triggering is achieved with a simplified structure, while saving space and achieving controllable costs.

[0040] As an example, the pair of wings 104 are typically arranged symmetrically with respect to the cantilever portion 105. Thus, the displacement generated by the same pressing force on a single wing 104 is the same, so that the pair of wings 104 located on both sides of the cantilever portion 105 pivot to the same extent relative to the cantilever portion 105, i.e., the triggering of the two circuits is equivalent.

[0041] According to an exemplary embodiment of the present disclosure, as shown in the figure, the cantilever portion 105 is bent from the fixing portion 103 toward the pair of wing portions 104 and extends in a transverse direction orthogonal to the longitudinal direction of the fixing portion 103 .

[0042] In a further embodiment, as shown in the figure, the cantilever portion 105 extends laterally from a lateral side edge of the fixing portion 103 at the middle portion along the longitudinal direction and then bends toward the pair of wings 104 and is connected between the pair of wings 104 .

[0043] Thus, through the arrangement of the cantilever portion 105, when a pressing force acts on one of the pair of wings 104, the wing 104 subjected to the pressing force is displaced toward the corresponding conductive pad 30 it faces. Accordingly, the cantilever portion 105 flexes toward the fixed portion 103, thereby achieving amplified displacement of the pressed wing 104 with a smaller pressing force, facilitating triggering of the corresponding circuit. Meanwhile, although the other wing 104, which is not subjected to the pressing force, tends to be driven toward the corresponding conductive pad 30 it faces as the cantilever portion 105 flexes, this displacement tendency is resisted or even offset by the reverse displacement tendency of the other wing 104, which is away from the corresponding conductive pad 30, caused by the "seesaw" motion of the pair of wings 104 of the conductive spring 102 relative to the cantilever portion 105. As a result, the other wing 104 remains disconnected from the corresponding conductive pad 30 and does not trigger the circuit where the corresponding conductive pad 30 corresponding to the other wing 104 resides.

[0044] In an exemplary embodiment of the present disclosure, further, for example, each wing 104 includes a corresponding bent conductive contact portion 106 located between the free end and the cantilever portion 105. Furthermore, in a first state in which the pair of wings 104 are free of force, the cantilever portion 105 forms an angle with the pair of wings 104 in a transverse plane perpendicular to the longitudinal direction of the fixed portion 103, and each conductive contact portion 106 is disconnected from the corresponding conductive pad 30 it faces. This first state is the initial state in which the pair of wings 104 are free of force. In this state, each conductive contact portion 106 of the pair of wings 104 remains disconnected from the corresponding conductive pad 30 it faces, and the circuits connected to all conductive pads 30 are in an open, untriggered state.

[0045] In a further embodiment, for example, as shown in the figure, each wing 104 has a straight portion 107 extending between the conductive contact portion 106 and the cantilever portion 105. Furthermore, as an example, when the trigger structure 10 is mounted in place relative to the circuit, the fixed portion 103 is fixed relative to the circuit, the conductive contact portion 106 of each wing 104 is arranged to bend toward the corresponding conductive pad 30, and the pair of wings 104 are pressed toward the fixed portion 103 so that the straight portion 107 of each wing 104 is substantially parallel to the surface of the fixed portion 103. At this time, the pair of wings 104 are both pressed so that the straight portion 107 is parallel to the surface of the fixed portion 103, thereby reliably holding the trigger structure 10 in place through the pressing.

[0046] In yet another further embodiment, for example, in the second state where one of the pair of wings 104 is subjected to a pressing force toward the fixing portion 103, the pair of wings 104 pivot about the cantilever portion 105, causing the corresponding conductive contact portion 106 of the one wing 104 to be pushed toward the corresponding conductive pad 30 and to be in conductive contact, while the corresponding conductive contact portion 106 of the other wing 104 is simultaneously displaced away from the corresponding conductive pad 30 and disconnected. In other words, in this case, the one of the pair of wings 104 is displaced toward the corresponding conductive pad 30 by the pressing force to such an extent that the conductive contact portion 106 of the one wing 104 and the conductive pad 30 are in conductive contact with each other, thereby triggering the circuit connected to the conductive pad 30; at the same time, the conductive contact portion 106 of the other wing 104 and the conductive pad 30 are moved away from each other due to the aforementioned "seesaw"-like pivoting, thereby maintaining a disconnected, untriggered state.

[0047] Furthermore, for example, when the pressing force ceases, the pair of wings 104 pivot about the cantilever portion 105 and return to the first state. In other words, when the pressing force acting on one of the wings 104 is removed, the pair of wings 104 reset themselves relative to the cantilever portion 105, pivoting in the opposite direction of the previous "seesaw"-like pivoting. Furthermore, due to the elastic reset action of the cantilever portion 105, the conductive spring 102 is reset as a whole, returning to the initial first state. Compared to the prior art, the trigger structure 10 disclosed herein, which can automatically reset itself in response to forces acting on different wings 104, essentially achieves a bidirectional automatic reset function, which is superior to the currently used dual micro switches, as the latter cannot achieve this bidirectional automatic reset function.

[0048] In an exemplary embodiment of the present disclosure, for example, the bottom surface of the fixing portion 103 facing away from the pair of wings 104 is provided with a grounded conductive contact 108, which is electrically connected to PIN 3. With this arrangement, the fixing portion 103 is installed in a pressing manner, so that the conductive contact 108 is also pressed against the corresponding ground and electrically connected thereto, thereby achieving reliable grounding of the fixing portion 103.

[0049] As a typical exemplary embodiment, for example, the conductive spring 102 is made of a metal material and molded in one piece, so the manufacturing process is simple. And because the metal is not easy to yield and has a strong current carrying capacity, it can generally withstand an instantaneous contact current of 1A to 2A, which is far greater than the rated contact current of about 0.1A that a conventional micro switch can withstand, so it is very safe for surges or

[0050] The trigger structure 10 of a circuit for an electronic lock in the field of electric vehicle charging based on the above-mentioned arrangement can achieve the following superior technical effects over existing technical solutions in the field (such as double micro switches arranged in opposite directions): a "seesaw" structure is realized in which the pair of wings 104 in the conductive spring 102 can move toward and away from the corresponding conductive pads 30 they face and pivot around the cantilever portion 105 between them, thereby replacing the conventional double micro switch trigger device with the help of only this single-piece trigger structure 10 with a simple structure, achieving reliable two-way triggering with a simplified structure, saving space, and achieving controllable costs. Moreover, due to the seesaw-like pivoting and the deflection of the cantilever portion 105, on the one hand, the amplified displacement of the pressed one wing 104 can be achieved with a smaller pressing force, which facilitates the contact between the conductive contact portion 106 of the pressed wing 104 and the facing conductive pad 30, thereby promoting the triggering of the corresponding circuit; on the other hand, the other wing 104 that is not under pressing pressure has a tendency to be driven to shift toward the corresponding conductive pad 30 it faces as the cantilever portion 105 deflects, and this displacement tendency is resisted or even offset by the reverse displacement tendency of the other wing 104 away from the corresponding conductive pad 30 caused by the "seesaw" movement of the pair of wings 104 of the conductive spring 102 relative to the cantilever portion 105, thereby maintaining the disconnection between the other wing 104 and the corresponding conductive pad 30 and preventing triggering. Moreover, when the aforementioned pressing force acting on one of the wings 104 is cancelled, the pair of wings 104 reset themselves relative to the cantilever portion 105, pivoting in the opposite direction of the previous "seesaw" type pivoting, and due to the elastic reset action of the cantilever portion 105, the conductive spring 102 is reset as a whole and restored to the initial first state. This trigger structure 10, which can reset itself in response to the forces acting on different wings 104, actually realizes a two-way automatic reset function.

[0051] FIG2 schematically illustrates a schematic diagram of an electronic lock according to an embodiment, wherein the electronic lock includes the trigger structure shown in FIG1 , wherein Figure 2(a) to Figure 2(g) The schematic diagram is shown in a perspective view, a front view, a rear view, a left view, a right view, a top view, and a bottom view, respectively, and the top cover of the housing has been removed for clarity. Figure 3 FIG. 2 is a schematic circuit diagram of the electronic lock according to an embodiment.

[0052] According to another aspect of the present disclosure, as shown in FIG. Figure 3 The present disclosure also provides an electronic lock 1, comprising: a shell 11; according to the aforementioned trigger structure 10, the conductive connecting member 101 and the fixed portion 103 of the conductive spring 102 are fixedly installed in the shell 11; a moving member 12, movably installed in the shell 11, and configured to move between a locked position and an unlocked position; and a locking pin 13, fixed in the shell 11, and extending to the outside of the shell 11 through a pin hole 110 on the shell 11. In a specific embodiment, for example, when the moving member 12 is moved to the locked position, one of the pair of wings 104 is pressed by the moving seat so that it is at least partially in conductive contact with the corresponding conductive pad 30, and the other wing 104 is moved away from the corresponding conductive pad 30; when the moving member 12 is moved to the unlocked position, the other wing 104 of the pair of wings 104 is pressed by the moving seat so that it is at least partially in conductive contact with the corresponding conductive pad 30, and the one wing 104 is moved away from the corresponding conductive pad 30.

[0053] For example, Figure 3 As shown, the switches S1 and S2 are substantially equivalent to the actions of applying pressing force to the left wing and the right wing as shown, ie, locking action and unlocking action respectively.

[0054] Figure 2 and Figure 3 As shown, in the illustrated embodiment, through this arrangement, the electronic lock 1 of the present disclosure can achieve convenient triggering of two corresponding circuits when switching between the locked position and the unlocked position using the single trigger structure 10, thereby realizing the locking and unlocking functions of the electronic lock 1. Compared with conventional circuit triggering devices with two micro switches arranged in opposite directions, the present trigger structure 10 achieves a bidirectional and self-resetting circuit triggering structure 10 with a simplified structure and space savings by virtue of the "seesaw"-like pivoting motion of the trigger structure 10 and the elastic flexure of the cantilever portion 105.

[0055] Preferably, in an exemplary embodiment according to the present disclosure, for example, as shown in the figure, the electronic lock 1 further includes: a driving device 14, installed in the housing 11; and a transmission device 15, installed in the housing 11 and disposed between the driving device 14 and the moving member 12, and forming a transmission connection between the driving device 14 and the moving member 12. In a further embodiment, the transmission device 15 is configured to convert the rotational motion output by the driving device 14 into linear motion, and drive the moving member 12 to translate between a locked position and an unlocked position.

[0056] In a more specific embodiment, for example, the driving device 14 is a motor shown in the figure, and the transmission device 15 includes, for example, as shown in the figure: a first transmission member 151, the first transmission member 151 includes a first bevel gear portion 1512 and a second spur gear portion 1513 coaxially and integrally arranged with each other about a first transmission shaft 1511 (the first transmission shaft 1511 is, for example, substantially orthogonal to the output shaft of the motor as shown in the figure), the first bevel gear portion 1512 is meshed with the output bevel gear sleeved on the output shaft of the motor to form a transmission connection; a second transmission member 152, the second transmission member 152 includes a second transmission shaft 1521 and a second spur gear portion 1513 coaxially and separately sleeved on the second transmission shaft 1521 (the second transmission shaft 1 521, for example, is parallel to the first transmission shaft 1511 as shown in the figure), the third spur gear portion 1522 and the fourth spur gear portion 1523 at both ends, the third spur gear portion 1522 of the second transmission member 152 is meshed with the second spur gear portion 1513 of the first transmission member 151 to form a transmission connection; and the third transmission member 153, the third transmission member 153 includes a fifth spur gear portion 1532 and a sixth spur gear portion 1533 coaxially and integrally arranged with each other about a third transmission shaft 1531 (the third transmission shaft 1531 is, for example, substantially parallel to the first transmission shaft 1511 and the second transmission shaft 1521), the fifth spur gear portion 1532 is meshed with the fourth spur gear portion 1523 to form a transmission connection.

[0057] Furthermore, in an exemplary embodiment, as shown in the figure, for example, the third transmission member 153 is mounted to the moving member 12 (for example, by the sixth spur gear portion 1533 being embedded in the moving member 12 ).

[0058] As an example, as shown in the figure, the housing 11 is provided with a slot 111 , and the trigger structure 10 is installed in place in the housing 11 by inserting the fixing portion 103 into the slot 111 .

[0059] Furthermore, in the illustrated embodiment, for example, the conductive spring 102 further includes a first stopper 1091. The first stopper 1091 includes two longitudinal ends of the fixing portion 103 that are bent toward corresponding wings 104 of the pair of wings 104, and is configured to abut against the inner wall of the slot 111 along the longitudinal direction. The provision of the first stopper 1091 allows the conductive spring 102 to abut against the inner wall of the slot 111 along the longitudinal direction in the slot 111 via the fixing portion 103, thereby preventing any rotation of the fixing portion 103 and any longitudinal translation, thereby preventing any longitudinal displacement of the conductive spring 102.

[0060] Furthermore, in the illustrated embodiment, for example, the conductive spring 102 further includes a second stopper, which includes a first protruding piece 1092 extending from an edge of the fixing portion 103 opposite the cantilever portion 105 and bent toward the pair of wings 104 at an acute angle with the first direction along which the fixing portion 103 is inserted into the slot 111. By providing the second stopper, since the first protruding piece 1092 of the second stopper forms an acute angle with the first direction along which the insertion movement is made, the first protruding piece 1092 of the second stopper can prevent the fixing portion 103 from falling out by pressing against the inner wall of the slot 111 after the fixing portion 103 is inserted into place.

[0061] Furthermore, in the illustrated embodiment, for example, the conductive spring 102 further includes a third stopper, comprising a plurality of second tabs 1093 extending from both side edges of the fixing portion 103 in a lateral direction perpendicular to the longitudinal direction toward the pair of wings 104 and bent toward the pair of wings 104 at an obtuse angle with respect to the first direction. The second tabs 1093 on each side edge are symmetrically distributed relative to the cantilever portion 105. By providing the third stopper, the plurality of second tabs 1093 of the third stopper form an obtuse angle with respect to the first direction of insertion. As a result, when the fixing portion 103 is inserted into the slot 111, the plurality of second tabs 1093 of the third stopper flex in accordance with the insertion movement, thereby not hindering such insertion. Furthermore, once the fixing portion 103 is inserted into place, the third stopper prevents any movement of the fixing portion 103 away from the slot 111, thereby ensuring reliable positioning along the first direction of insertion.

[0062] In an exemplary embodiment according to the present disclosure, for example, as shown in the figure, the moving member 12 includes: a front end portion 121, the locking pin 13 is fixed to the front end portion 121; and an extension portion 122, the extension portion 122 extending from the front end portion 121 and having a protrusion, the extension portion 122 being configured to press the one wing 104 of the pair of wings 104 with the protrusion when the moving member 12 moves to the locked position, and to press the other wing 104 of the pair of wings 104 with the protrusion when the moving member 12 moves to the unlocked position. By providing the protrusion, it is convenient to make the protrusion contact and press one of the pair of wings 104 through the longitudinal translation of the moving member 12 to apply a unilateral pressing force to the "seesaw" type pivot structure of the conductive spring 102.

[0063] Moreover, in a more specific embodiment, for example, as shown in the figure, the third transmission member 153 is installed to the moving member 12 by embedding the sixth spur gear portion 1533 in the moving member 12, which is essentially achieved by providing a toothed groove 111 in the extension portion 122 and the toothed groove 111 is consistent with the tooth shape of the sixth spur gear portion 1533, so that the translation of the moving member 12 along the longitudinal direction can be essentially equivalently regarded as coming from the gear-rack transmission between the second transmission member 152 and the third transmission member 153.

[0064] As a further embodiment, preferably, for example, as shown in the figure, the conductive spring 102 further includes a fourth stopper 1094, and the fourth stopper 1094 includes two free ends of the pair of wings 104, each bent toward the fixed portion 103. By providing the fourth stopper 1094, the range of motion of the protrusion on the moving member 12 is restricted, thereby stopping the movement of the protrusion along the longitudinal direction to prevent the moving member 12 from completely separating from the conductive spring 102 and causing trigger failure, that is, the movement of the moving member 12 can no longer apply pressing force to the pair of wings 104.

[0065] As an exemplary embodiment, for example, as shown in the figure, in the socket assembly, the shell 11 also includes a closing member 114, which is sleeved on the locking pin 13 and attached to the outer wall surface of the side wall of the shell 11 to close the gap between the locking pin 13 and the hole wall of the pin hole 110.

[0066] And in a further embodiment, for example, as shown in the figure, the closure member 114 includes: a main body 1141 and a plurality of connecting legs 1142. The main body 1141 is formed with a pin through hole 1140 for the locking pin 13 to pass through. The plurality of connecting legs 1142 are connected to the main body 1141. A plurality of plug-in holes 1143 are formed on the outer wall surface of the side wall of the shell 11, and the plurality of connecting legs 1142 are respectively plugged into the plurality of plug-in holes 1143. The hole wall of the pin through hole 1140 on the closure member 114 is interference fit with the locking pin 13, and the main body 1141 is tightly attached to the outer wall surface of the side wall of the shell 11. In this way, the gap between the locking pin 13 and the hole wall of the pin hole 110 can be reliably sealed by the closure member 114.

[0067] Furthermore, as an example, in the illustrated embodiment, a plurality of (four as shown) positioning holes are formed around the pin through hole 1140 on the main body 1141 of the closure member 114, and a plurality of (four as shown) raised positioning columns are correspondingly formed around the pin hole 110 on the outer wall surface of the side wall of the shell 11. The plurality of raised positioning columns are respectively inserted into the plurality of positioning holes to guide the closure member and the pin to cooperate with each other and then be correctly installed to the shell 11.

[0068] As an exemplary embodiment, for example, as shown in the figure, in the socket assembly, the shell 11 also includes a cable through hole 112 for guiding the cable to pass through (the cable is used for electrical connection, for example) and a rope through hole 113 for allowing a pulling rope to pass through (the pulling rope, for example, allows the moving part 12 to be manually reset to the unlocked position, thereby achieving manual unlocking) located at the end opposite to the front end portion 121 of the moving part 12 for fixing the locking pin 13.

[0069] Furthermore, considering that the electronic lock 1 provided in another aspect of the present disclosure includes the aforementioned trigger structure 10 , it also has the advantages of the aforementioned trigger structure 10 for the circuit of the electronic lock, which will not be described in detail here.

[0071] According to another aspect of the present disclosure, as shown in FIG4 , the present disclosure further provides a socket assembly for inserting a charging gun for charging, comprising: a charging socket; and the aforementioned electronic lock 1 , mounted to the charging socket. In an exemplary embodiment, for example, when the movable member 12 is moved to the locked position, the locking pin 13 engages with the charging gun inserted into the charging socket to prevent the charging gun from being removed from the charging socket; and when the movable member 12 is moved to the unlocked position, the locking pin 13 disengages from the charging gun inserted into the charging socket to allow the charging gun to be removed from the charging socket.

[0072] Furthermore, considering that the socket assembly provided in another aspect of the present disclosure includes the aforementioned trigger structure 10 of the circuit for the electronic lock and the aforementioned electronic lock 1, it also has the advantages of the aforementioned trigger structure 10 and the aforementioned electronic lock 1, which will not be repeated here.
