Description

Technical Field

[0001] The utility model relates to charging equipment, in particular to a vehicle charging socket. Background Art

[0002] More and more vehicles such as cars are starting to switch to electric drive. Therefore, the use of charging piles is also increasing. The charging piles include plugs and sockets, and the circuit is connected by plugging the plugs and sockets together.

[0003] In the current charging pile, neither the plug nor the socket is provided with a protective door, and it is easy for the user to put his finger into the socket, thus causing electric shock. In order to solve the above technical problems, the publication number CN117117539A discloses a technical solution entitled "A socket with a safety anti-touch door at the end of a new energy charging pile", which includes a seat body, an annular lower cover fixed to the top of the seat body, an upper cover rotatably provided on the annular lower cover, a movable seat movably mounted on the annular lower cover, a first door cover rotatably mounted on the annular lower cover and opened or closed with the movement of the movable seat, and a second door cover rotatably mounted on the annular lower cover and opened or closed with the movement of the movable seat. The first door cover and the second door cover can partially or completely cover the charging channel in the middle of the annular lower cover when closed; the annular lower cover is also provided with a first spring elastically abutting against the movable seat and used to push the movable seat to drive the first door cover and the second door cover to close.

[0004] In the above technical solution, since there is no locking mechanism, when the charging gun plug is not inserted, the door cover can be easily pushed to expose the charging channel on the socket. Although there are other technical solutions to solve the above problem by setting a separate locking assembly, the separately set locking assembly has its own sliding member, which is equivalent to setting two sliding members in the socket, and the movement relationship of the two sliding members needs to be accurately controlled. Due to problems such as manufacturing and installation gaps, the locking assembly may not be able to cooperate well with the protective door. For example, the locking member may not be fully unlocked, and the protective door will move, causing the protective door and the locking member to be stuck and unable to unlock and open the protective door; or after the charging plug is unplugged, the locking member has moved into place, and the protective door moves into place later, resulting in the locking member being unable to lock the protective door, thereby causing the protective door to be unable to open or the locking assembly to fail to work normally to achieve the expected locking effect. Utility Model Content

[0005] The utility model aims to provide a vehicle charging socket, which can effectively solve the problem that the existing charging pile protection door and locking mechanism are separately arranged, which is prone to poor coordination and causes the protection door to be unable to open or the locking mechanism to be unable to function normally.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] A vehicle charging socket comprises a socket body, wherein the socket body comprises a charging port, wherein a plurality of pin holes are arranged in the charging port, and the charging port is used for docking a charging plug.

[0008] The socket body is provided with a movable part and a protection door, the movable part is slidably arranged on the socket body and is transmission-connected to the protection door; the protection door is swingably arranged in the socket body, the movable part drives the protection door to swing, and the protection door closes or opens the pin insertion hole during the swinging process;

[0009] The movable part is provided with an error-opening part and a first limiting part, the socket body is provided with a stop part, and the protective door is provided with a second limiting part. The error-opening part stops the second limiting part, and the stop part stops the first limiting part, so that the protective door is in a closed pin socket position; the movable part moves toward the bottom of the charging port to release the stopping state of the second limiting part and the error-opening part, and releases the stopping state of the stop part and the first limiting part, and then the movable part moves in the direction away from the charging port to drive the protective door to swing and open the pin socket.

[0010] In the above vehicle charging socket, the protection door is located between the erroneous opening portion and the entrance of the charging port, the erroneous opening portion protrudes toward the entrance of the charging port, and the erroneous opening portion is located on the swing path of the protection door when it is opened.

[0011] In the above-mentioned vehicle charging socket, a card slot is opened on the protection door, and the side wall of the card slot forms the second limiting portion, which abuts against the erroneous opening portion; or, the second limiting portion is located on the side wall of the protection door, which abuts against the erroneous opening portion.

[0012] In the above-mentioned vehicle charging socket, a sliding opening is opened on the side wall of the charging port, and the end of the movable part is provided with a driving end extending from the sliding opening into the charging port. When the charging plug is inserted, the driving end is pushed to make the limiting part disengage from the mistaken opening part, and then the driving end slides out of the sliding opening.

[0013] In the above-mentioned vehicle charging socket, the first limiting portion is provided on the driving end, and the stopping portion is provided on the charging port next to the sliding port.

[0014] In the above-mentioned vehicle charging socket, the first limiting portion is arranged on the side wall of the driving end and protrudes from the side wall of the driving end, and a groove is formed on the side wall of the charging port next to the sliding port to form the stop portion.

[0015] In the above-mentioned vehicle charging socket, the first limiting portion protrudes toward the entrance direction of the charging port, and the distance between the side wall of the movable part away from the entrance direction of the charging port and the side wall of the sliding opening away from the entrance direction of the charging port is greater than or equal to the distance of the movable part protruding from the first limiting portion.

[0016] In the above vehicle charging socket, one of the movable part and the protective door is provided with a guide groove, and the other is provided with a guide rod extending into the guide groove.

[0017] In the above-mentioned vehicle charging socket, a first restoring member is further provided between the socket body and the movable member, so as to keep the erroneous opening portion and the second limiting portion in an abutting state.

[0018] In the above vehicle charging socket, a second restoring member is provided between the movable member and the socket body to restore the movable member to an initial position.

[0019] Compared with the prior art, the advantages of the utility model are:

[0020] The movable part is used to lock the relative positions of the socket body, the movable part and the protective door when no external force is applied, thereby solving the problem that the current protective door and the locking mechanism are separately arranged, resulting in poor coordination and the inability of the locking mechanism to function. The protective door of this solution is set in the socket body in a swinging manner, which makes the opening of the protective door smoother, and the swinging method allows the movable part to move a smaller distance to drive the protective door to open the pin socket, thereby reducing the movement range of the movable part and realizing the rapid opening and closing of the protective door. The protective door can block the pin socket on the socket body to prevent foreign objects from being inserted into the pin socket and avoid safety accidents, and the opening and closing of the protective door is driven by the movable part. When the charging plug is inserted into the charging port, the movable part will be pushed to open the protective door, so that no additional operation steps are added to the customer. In this solution, not only are stops set at the mis-opening part and the second limiting part, so that the movable part can limit the opening of the protective door, but also a stop part is set to stop the first limiting part, and the stop part is used to limit the movement of the movable part. Therefore, when there is no external force, the movable part and the charging port remain relatively still due to the stop part stopping the first limiting part, and the mis-opening part stops the second limiting part, so that the movable part and the protective door remain relatively still. At this time, if force is applied to the protective door, the stop of the mis-opening part will prevent the protective door from swinging. Through the two sets of stop relationships, two protection mechanisms are formed to ensure that the protective door will not open accidentally. When the protective door needs to be opened, the movable part and the protective door can be unlocked by driving the movable part, and the protective door can also be driven to open by driving the movable part. The linkage relationship formed between the movable part and the protective door also makes the unlocking and driving processes smoother.

[0021] Furthermore, the protection door is located between the false opening part and the entrance of the charging port, the false opening part protrudes toward the entrance of the charging port, and the false opening part is located on the swing path when the protection door is opened. The movement direction of the movable part when releasing the false opening part and the second limit part is consistent with the direction in which the movable part is pushed when the charging plug is inserted, and the unlocking process is smoother.

[0022] Furthermore, the protection door is provided with a slot, and the side wall of the slot forms the second limit portion, which abuts against the erroneous opening portion; or the second limit portion is located on the side wall of the protection door, abuts against the erroneous opening portion. The two different second limit portion setting positions can both release the blocking state of the erroneous opening portion and the second limit portion when the movable part is pushed by the charging plug.

[0023] Furthermore, a sliding opening is provided on the side wall of the charging port, and the end of the movable member is provided with a driving end extending from the sliding opening into the charging port. When the charging plug is inserted, the driving end is pushed to disengage the limit portion from the erroneous opening portion, and then the driving end slides out of the sliding opening. The sliding opening facilitates the driving end to extend into the charging port. When the charging plug is inserted into the charging port, the charging plug pushes the driving end, releases the stop state, and pushes the protective door to open through the movable member.

[0024] Furthermore, the first limiting part is provided on the driving end, and the stop part is provided on the charging port next to the sliding port. The first limiting part is provided on the driving end, and the stop part is provided by using the sliding port, so that no additional parts are provided on the socket body to form the stop part, thereby simplifying the socket body structure.

[0025] Furthermore, the first limiting portion is arranged on the side wall of the driving end and protrudes from the side wall of the driving end, and a groove is provided on the side wall of the charging port next to the sliding port to form the stop portion. The protruding first limiting portion and the stop portion formed by the groove can form a larger surface-to-surface contact, ensuring the stability of the first limiting portion and the stop portion when they are hooked, and not easy to loosen, and the stop state can be released only when pushed by the charging plug.

[0026] Furthermore, the first limiting portion protrudes toward the entrance direction of the charging port, and the distance between the side wall of the movable member away from the entrance direction of the charging port and the side wall of the sliding opening away from the entrance direction of the charging port is greater than or equal to the distance of the first limiting portion protruding from the movable member. The protruding direction of the first limiting portion is opposite to the movement direction when the charging plug is inserted into the charging port, that is, when the charging plug is inserted, the first limiting portion can be directly pushed away from the stop portion, allowing the first limiting portion to enter the sliding opening, so that the subsequent movable member can slide in the direction away from the charging port.

[0027] Furthermore, one of the movable part and the protective door is provided with a guide groove, and the other is provided with a guide rod extending into the guide groove. Through the cooperation of the guide groove and the guide rod, the protective door can be driven to swing stably when the movable part slides, and the speed of opening the protective door can be controlled by the angle of the guide groove.

[0028] Furthermore, a first reset member is provided between the socket body and the movable member to keep the erroneous opening portion and the second limit portion in abutment. The first reset member is mainly used to keep the second limit portion and the erroneous opening portion in a stopped state when the movable member is not subjected to external force, so as to prevent the second limit portion and the erroneous opening portion from releasing the stopped state due to vibration or accidental collision.

[0029] Furthermore, a second reset member is provided between the movable member and the socket body to restore the movable member to an initial position. After the charging plug is unplugged, the second reset member pushes the movable member back to the initial position and simultaneously drives the protective door back to the position of shielding the pin insertion hole.

[0042] A vehicle charging socket, comprising a socket body 100, the socket body 100 comprising a charging port 110, the charging port 110 being provided with a plurality of pin holes 111, the charging port 110 being used to dock with a charging plug, the socket body 100 being provided with a movable part 200 and a protective door 300, the movable part 200 being slidably arranged on the socket body 100 and being transmission-connected to the protective door 300; the protective door 300 being swingably arranged in the socket body 100, the movable part 200 driving the protective door 300 to swing, the protective door 300 closing or opening the pin holes 111 during the swinging process; the movable part 200 being provided with an erroneous opening part 21 0 and a first limiting portion 220, the socket body 100 is provided with a stop portion 120, and the protection door 300 is provided with a second limiting portion 310, the erroneous opening portion 210 stops the second limiting portion 310, and the stop portion 120 stops the first limiting portion 220, so that the protection door 300 is in a closed pin plug hole 111 position; the movable part 200 moves toward the bottom direction of the charging port 110 to release the stopping state of the second limiting portion 310 and the erroneous opening portion 210, and releases the stopping state of the stop portion 120 and the first limiting portion 220, and then the movable part 200 moves in the direction away from the charging port 110 to drive the protection door 300 to swing and open the pin plug hole 111.

[0043] The movable part 200 is used to lock the relative positions of the socket body, the movable part 200 and the protective door 300 when no external force is applied, so as to solve the problem that the current protective door 300 and the locking mechanism are separately arranged, resulting in poor coordination and the inability of the locking mechanism to function. The protective door 300 of this solution is set in the socket body 100 in a swinging manner, and the protective door 300 opens more smoothly. In addition, the swinging manner allows the movable part 200 to move a smaller distance to drive the protective door 300 to open the pin socket 111, thereby reducing the range of motion of the movable part 200 and realizing the rapid opening and closing of the protective door 300. The protective door 300 can block the pin socket 111 on the socket body 100 to prevent foreign objects from being inserted into the pin socket 111, avoiding safety accidents, and the opening and closing of the protective door 300 are driven by the movable part 200. When the charging plug is inserted into the charging port 110, the movable part 200 will be pushed to open the protective door 300, so that no additional operation steps are added to the customer. In the present solution, not only are stops provided on the false opening portion 210 and the second limiting portion 310 so that the movable part 200 can limit the opening of the protective door 300, but a stop portion 120 is also provided to stop the first limiting portion 220. The stop portion 120 is used to limit the movement of the movable part 200. Therefore, when there is no external force, the stop portion 120 stops the first limiting portion 220, so that the movable part 200 and the charging port 110 remain relatively still, and the false opening portion 210 stops the second limiting portion 310, so that the movable part 200 and the protective door 300 remain relatively still. At this time, if force is applied to the protective door 300, the stop of the false opening portion 210 will prevent the protective door 300 from swinging. Through the two sets of stop relationships, two protection mechanisms are formed to ensure that the protective door 300 will not be opened accidentally. When the protective door 300 needs to be opened, the movable part 200 and the protective door 300 can be unlocked by driving the movable part 200. The protective door 300 can also be opened by driving the movable part 200, which makes the unlocking and driving processes smoother.

[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0047] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] See also Figures 1 to 6 This is an embodiment of a vehicle charging socket of the utility model, the vehicle charging socket includes a socket body 100, the socket body 100 is provided with a charging port 110, the charging port 110 is provided with a plurality of pin holes 111, the shape and specification of the charging port 110 are uniformly manufactured according to local standards, the number and position of the pin holes 111 are also uniformly arranged according to local standards, the charging port 110 is used to connect to a charging plug, and the charging plug is also manufactured according to local standards.

[0049] The socket body 100 is provided with a movable part 200 and a protective door 300. The main function of the movable part 200 is to drive the protective door 300 to move and realize the opening and closing of the protective door 300. The movable part 200 is in a plate or block shape. The movable part 200 is arranged on the socket body 100 and is connected to the protective door 300 by transmission. The protective door 300 is swingably arranged in the socket body 100. The movable part 200 is slidably arranged in the socket body 100, and the pin insertion hole 111 is closed or opened during the swinging process by the protective door 300. Since the movable part 200 needs to drive the protective door 300 to slide when the charging plug is inserted, the movable part 200 generally needs to be arranged closer to the entrance of the charging port 110 relative to the protective door 300.

[0050] The movable part 200 is provided with an incorrect opening portion 210 and a first limiting portion 220, the socket body 100 is provided with a stop portion 120, and the protection door 300 is provided with a second limiting portion 310. The incorrect opening portion 210 stops the second limiting portion 310, and the stop portion 120 stops the first limiting portion 220, so that the protection door 300 is in a position to close the pin plug hole 111, thereby preventing foreign matter from entering the pin plug hole 111. When the charging plug is inserted into the charging port 110, the charging plug pushes the movable member 200 to move toward the bottom of the charging port 110, so that the false opening portion 210 and the second limiting portion 310 are unblocked, and the stop portion 120 and the first limiting portion 220 are also unblocked; then the movable member 200 changes the direction of movement and moves in the direction away from the charging port 110. In this process, the movable member 200 drives the protection door 300 to swing, so that the protection door 300 opens the pin socket 111, allowing the charging plug to dock with the pin socket 111, and realizes the electrical connection between the two. By setting the socket body 100 to stop the movable member 200, and the movable member 200 to stop the protection door 300, when no external force is applied, the relative positions of the socket body 100, the movable member 200 and the protection door 300 are fixed, and the protection door 300 cannot be opened by simply pushing the protection door 300 or pressing the movable member 200. The protection door 300 can only be opened by contacting the stopper according to the steps, thereby greatly improving the safety.

[0051] Furthermore, the protective door 300 is located between the mis-opening portion 210 and the entrance of the charging port 110, and the mis-opening portion 210 protrudes toward the entrance of the charging port 110, so that when the charging gun is inserted to push the movable member 200, the moving direction of the mis-opening portion 210 is consistent with the direction in which the movable member 200 is initially pushed, so that the mis-opening portion 210 can be better separated from the second limiting portion 310. The mis-opening portion 210 is located on the swinging path when the protective door 300 is opened, so that when the movable member 200 does not move, the mis-opening portion 210 is always in a position to block the opening of the protective door 300, thereby achieving the purpose of not being able to open the protective door 300 even if the protective door 300 is only moved.

[0052] The second limiting portion 310 can be set in multiple positions, including but not limited to the following structures: one is to open a slot 320 on the protection door 300, and the side wall of the slot 320 forms the second limiting portion 310, and the false opening portion 210 extends into the slot 320 to form a stop relationship with the side wall of the slot 320, thereby preventing the protection door 300 from opening; the other is that the second limiting portion 310 is located on the side wall of the protection door 300 and abuts against the false opening portion 210, that is, the false opening portion 210 is equivalent to forming an embracing structure to prevent the protection door 300 from opening.

[0053] The following is an introduction to the structural forms of the stopper 120 and the first limiting portion 220. The stopper 120 can be set on the socket body 100 alone or on an existing component of the socket body 100. The stopper 120 can be added to the existing component of the socket body 100, or a hole or groove can be dug on the existing component of the socket body 100 to form the stopper 120. The position of the first limiting portion 220 is set according to the position of the stopper 120, and it is necessary to meet the requirement that when the movable part 200 is pushed by the charging plug to move toward the bottom of the charging port 110, the stopper 120 and the first limiting portion 220 can release the blocking state. It is best that the stopper 120 and the first limiting portion 220, the mis-opening portion 210 and the second limiting portion 310 can release the blocking synchronously.

[0054] A sliding opening 112 is provided on the side wall of the charging port 110. The sliding opening 112 is mainly used to allow the movable part 200 to partially extend into the charging port 110. A driving end 230 extending into the charging port 110 is provided on the movable part 200, so that the movable part 200 can be pushed to move when the charging plug is inserted into the charging port 110. The first limiting part 220 can be disengaged from the stop part by pushing the driving end 230 through the charging plug, thereby releasing the stop state.

[0055] The positions of the first limiting portion 220 and the stopper portion include but are not limited to the following two:

[0056] One is to set the first limiting portion 220 on the driving end 230, and the stopping portion is located on the charging port 110 next to the sliding opening 112, the first limiting portion 220 abuts against the stopping portion in a direction away from the center of the charging port 110, the stopping portion can be directly the inner wall of the charging port 110 next to the sliding opening 112, and the first limiting portion 220 is directly pressed on the inner wall of the charging port 110, and due to the abutment relationship between the first limiting portion 220 and the stopping portion, after the charging plug contacts the driving end 230, the driving end 230 cannot be pushed out of the charging port 110 from the sliding opening 112, but can only be pushed to the depth of the charging port 110, but it is such a push that can cause the first limiting portion 220 and the stopping portion to disengage and release the stopping state.

[0057] Furthermore, the first limiting portion 220 is arranged on the side wall of the driving end 230 and protrudes from the side wall of the driving end 230. A groove is opened on the side wall of the charging port 110 next to the sliding opening 112 to form a stop portion, that is, a concave-convex fit is formed, so that the first limiting portion 220 and the stop portion can form a more stable stop state, and will not easily contact the stop when subjected to external vibration or accidental touch.

[0058] Another method is to set the first limiting portion 220 on the movable part 200 outside the charging port 110, and the stopping portion is set on the socket body 100 at a position corresponding to the movable part 200. Generally, the first limiting portion 220 is protrudingly set, so that there is a larger setting space outside the charging port 110, which can facilitate the arrangement of the first limiting portion 220 and the stopping portion, thereby making the first limiting portion 220 and the stopping portion more stable in the stopped state.

[0059] The first limiting portion 220 can protrude in two directions, namely, protruding toward the entrance of the charging port 110 or protruding perpendicular to the direction of insertion of the charging plug. It is also acceptable if it is between the above two protruding directions, and the charging plug can also be driven to release the stopping state of the first limiting portion 220 and the stopping portion.

[0060] For the first limiting portion 220 protruding toward the entrance of the charging port 110, because a sufficient distance must be reserved for the first limiting portion 220 and the stopping portion to be able to disengage, the distance between the side wall of the movable part 200 away from the entrance of the charging port 110 and the side wall of the sliding opening 112 away from the entrance of the charging port 110 is ≥ the distance of the movable part 200 protruding from the first limiting portion 220; and for the first limiting portion 220 protruding in a direction perpendicular to the insertion direction of the charging plug, the distance between the side wall of the movable part 200 away from the entrance of the charging port 110 and the side wall of the sliding opening 112 away from the entrance of the charging port 110 is ≥ the distance the first limiting portion 220 moves on the stopping portion when it is out of the stopping state.

[0061] In this embodiment, two protective doors 300 are symmetrically arranged along the vertical center line of the charging port 110. The end of each protective door 300 is rotatably connected to the socket body 100. A guide rod 330 is provided on the protective door 300, and a guide groove 240 cooperating with the guide rod 330 is provided on the movable part 200. The distance between the guide groove 240 and the rotating end of the protective door 300 and the inclination angle of the guide groove 240 can control the speed at which the movable part 200 drives the protective door 300 to open and close, and can also adjust the length of the movement stroke of the movable part 200 when the protective door 300 is opened.

[0062] A first reset member 400 is provided between the socket body 100 and the movable member 200. The first reset member 400 is used to keep the false opening portion 210 and the second limiting portion 310, and the first limiting portion 220 and the stop portion in abutment state, so as to prevent the movable member 200 from accidentally releasing the stop state. The first reset member 400 of this embodiment is a spring sheet, one end of which is fixedly connected to the socket body 100, and the other end of which is abutted against the movable member 200, and moves relative to the movable member 200 when the movable member 200 moves. The direction of the elastic force generated by the first reset member 400 is opposite to the direction in which the movable member 200 moves to release the stop state.

[0063] In addition, the movable member 200 is also connected to a second reset member 500. After the charging plug is removed, the second reset member 500 pushes the movable member 200 back to its original position, allowing the driving end 230 to extend into the charging port 110, and driving the protective door 300 to close. The second reset member 500 is located between the socket body 100 outside the charging port 110 and the movable member 200. When the charging plug is inserted into the charging port 110, the movable member 200 moves to accumulate elastic potential energy in the second reset member 500. When the charging plug is pulled out, the elastic potential energy of the second reset member 500 is released, driving the movable member 200 to return to its initial position, so that the protective door 300 closes the pin insertion hole 111.

[0064] The second reset member 500 generally adopts a compression spring. The socket body 100 and the movable member 200 are both provided with positioning members for fixing the second reset member 500. The positioning members include a positioning groove 140 and / or a positioning rod 150. In this embodiment, both the positioning groove 140 and the positioning rod 150 are used. The end of the second reset member 500 is inserted into the positioning groove 140, the positioning rod 150 is arranged in the positioning groove 140, and the positioning rod 150 extends into the second reset member 500. In this way, the two ends of the second reset member 500 are fixed to ensure that the second reset member 500 can play an expected role and drive the movable member 200 to reset after the charging plug is unplugged.

[0065] The protective door 300 in this embodiment has two leaves and is symmetrically arranged along the vertical center line of the charging port 110, and the movable part 200 is also symmetrically arranged about the vertical center line of the charging port 110. The two protective doors 300 are arranged in parallel and are located between the movable part 200 and the socket body 100. The bottom end of the protective door 300 is provided with a rotating hole 340, and the socket body 100 is provided with a rotating shaft 130 inserted into the rotating hole 340, so as to realize the swing of the protective door 300 relative to the socket body 100. A slider 160 is also provided on the socket body 100 to support the protective door 300, ensuring that the protective door 300 swings in a direction perpendicular to the insertion direction of the charging plug, and avoiding the protective door 300 shaking during the swinging, causing the protective door 300 to be unable to close the pin socket 111. In the initial state, the protective door 300 and the movable part 200 leave a gap along the direction of the charging plug insertion, so that the movable part 200 has enough space to move along the direction of the charging plug insertion to contact the stop state.

[0066] A slide groove 113 is provided on the surface of the socket body 100 corresponding to the protective door 300. The protective door 300 includes a shielding portion. The shielding portion 350 extends through the slide groove 113 into the charging port 110. The shielding portion 350 shields the pin insertion hole 111 to achieve the purpose of closing the pin insertion hole 111. The driving end 230 of the movable part 200 extending into the charging port 110 is provided with an inclined surface 231. When the charging plug is inserted into the charging port 110, the end face of the charging plug abuts against the inclined surface 231 of the driving end 230, but the downward thrust generated will be offset by the abutment force between the first limit portion 220 and the stopper. Therefore, when the charging plug wants to move into the charging port 110, the movable part 200 will first move into the charging port 110 together with the charging plug. As the movable part 200 moves, the first limiting portion 220 will release the abutment with the stopper, and the false opening portion 210 will also release the abutment with the second limiting portion 310. At this time, the charging plug generates a downward thrust on the movable part 200, which will push the movable part 200 to gradually withdraw from the charging port 110. As the movable part 200 moves perpendicular to the insertion direction of the charging plug, the movable part 200 will also drive the protection door 300 to swing, so that the protection door 300 opens the pin socket 111, and the charging plug is inserted into the pin socket 111, and the vehicle starts to charge.

[0067] After charging is completed, the charging plug is pulled out of the charging port 110, and the second reset member 500 will generate an upward thrust, pushing the driving end 230 of the movable member 200 through the sliding opening 112 into the charging port 110. The movement of the movable member 200 will drive the protection door 300 to swing and close the pin insertion hole 111. At the same time, the first reset member 400 will generate a thrust in the direction of the charging plug being pulled out, pushing the mis-opening portion 210 to stop with the second limiting portion 310, and the first limiting portion 220 to stop with the stopping portion, and the movable member 200 and the protection door 300 will return to their initial positions.

[0068] Through the above scheme, when no charging gun is inserted, the stopper and the first limiting part 220 are stopped, so that the movable part 200 cannot move in the direction of driving the protective door 300 to open, and the false opening part 210 and the second limiting part 310 are stopped, and the protective door 300 cannot be opened even if it is pushed, thereby adding an anti-false opening function to both the movable part 200 and the protective door 300. Only when the charging plug is inserted and the movable part 200 is pushed to move, can the stopping state of the false opening part 210 and the first limiting part 220, and the stopper and the first limiting part 220 be released at the same time, and then with the insertion of the charging plug, the movable part 200 will be pushed out of the charging port 110 and drive the protective door 300 to open the pin socket 111, so that the charging plug can dock with the pin socket 111 to realize charging, thereby making the charging socket safer.

[0069] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
