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, Chinese Patent Publication No. 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 open or closed with the movement of the movable seat, and a second door cover rotatably mounted on the annular lower cover and open 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 movable parts, which is equivalent to setting two movable parts in the socket, and the movement relationship of the two movable parts 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 the 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, comprising a socket body, wherein the socket body is provided with a charging port, wherein the charging port is provided with a plurality of wire jacks, wherein the charging port is used to connect with a charging plug, wherein a movable part and a protective door are provided in the socket body, wherein the movable part is provided on the socket body and is transmission-connected to the protective door; wherein the protective door is slidably provided in the socket body to close or open the wire jacks during the sliding process;

[0008] A limiting portion is provided on the movable part, and an incorrect opening portion is provided on the socket body. The incorrect opening portion stops the limiting portion, so that the protection door is in a closed wire insertion hole position; the movable part moves toward the bottom of the charging port to release the stopping state of the limiting portion and the incorrect opening portion, and then the movable part moves in a direction away from the charging port to drive the protection door to slide and open the wire insertion hole.

[0009] 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 enter the sliding opening.

[0010] In the above-mentioned vehicle charging socket, the limiting portion is provided on the driving end, the mis-opening portion is provided on the charging port next to the sliding port, and the limiting portion abuts against the mis-opening portion.

[0011] In the above-mentioned vehicle charging socket, the 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 opened on the side wall of the charging port next to the sliding port to form the false opening portion.

[0012] In the above-mentioned vehicle charging socket, the limiting portion is provided on the movable member located outside the charging port, the erroneous opening portion corresponds to the position of the limiting portion, and the limiting portion abuts against the erroneous opening portion.

[0013] In the above vehicle charging socket, the limiting portion protrudes toward the entrance of the charging port, and the distance between the side wall of the movable part away from the entrance of the charging port and the side wall of the sliding opening away from the entrance of the charging port is greater than or equal to the distance of the limiting portion protruding from the movable part.

[0014] In the above-mentioned vehicle charging socket, the limiting portion protrudes in a direction perpendicular to the insertion direction of the charging plug, and the distance between the side wall of the movable part away from the charging port entrance direction and the side wall of the sliding opening away from the charging port entrance direction is greater than or equal to the distance the limiting portion moves out of the stop state.

[0015] In the above vehicle charging socket, a first reset member is further provided between the socket body and the movable member, so as to keep the limiting portion and the erroneous opening portion in an abutting state.

[0016] In the above vehicle charging socket, the first restoring member is a spring, one of the socket body and the movable member is fixedly connected to the first restoring member, and the other one is in contact with the first restoring member.

[0017] In the above-mentioned vehicle charging socket, one of the movable part and the protective door is provided with a first slide groove, and the other is provided with a first sliding part sliding in the first slide groove; one of the protective door and the socket body is provided with a second slide groove, and the other is provided with a second sliding part sliding in the second slide groove, and the first slide groove and the second slide groove are not parallel.

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] By setting a limit part on the movable part, setting an erroneous opening part on the socket body, and the erroneous opening part stopping the limit part, the problem that the current protective door and the locking mechanism are separately set, resulting in poor coordination and the inability of the locking mechanism to function, is solved. The protective door in this solution is set in the socket body in a sliding manner, and the protective door opens more smoothly. The protective door can block the wire jack on the socket body to prevent foreign objects from being inserted into the wire jack and avoid safety accidents. The protective door is driven to open and close 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, thereby not adding extra operation steps to the customer. By arranging a limit part on the movable part and an incorrect opening part on the socket body, the socket body always remains in a stationary state when the charging plug is inserted or pulled out. Therefore, the limit part can cooperate with the incorrect opening part more accurately to realize the stopping state or release the stopping state. When the charging plug is inserted, the movable part is pushed to make the movable part contact the stopping state of the limit part and the incorrect opening part first, and then the protective door is driven by the movable part to slide and open the wire jack. Unlocking and opening the wire jack are realized in turn by one movable part, so that the whole process is more continuous, and the unlocking and opening of the wire jack will not occur simultaneously, thereby avoiding the situation that the protective door is stuck and cannot be opened. In addition, the above structure does not need to consider the positional relationship of the two movable parts as in the prior art, and the installation accuracy requirement is reduced, which is conducive to improving assembly efficiency.

[0020] Furthermore, a sliding opening is provided 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, and when the charging plug is inserted, the driving end is pushed to disengage the limit part from the false opening part. The sliding opening facilitates the driving end to extend into the charging port, and when the charging plug is inserted into the charging port, the charging plug can also push the driving end to release the stop state and push the protective door to open through the movable part.

[0021] Furthermore, the limiting part is provided on the driving end, and the mis-opening part is provided on the charging port next to the sliding port, and the limiting part abuts against the mis-opening part. The limiting part is arranged in a position to abut against the mis-opening part in a direction away from the center of the charging port, so that when the charging gun pushes the driving end, the resistance of the limiting part to the movement of the mis-opening part relative to the mis-opening part is reduced, and the limiting part is not easy to be loosened from the mis-opening part when no external force is applied.

[0022] Furthermore, the limit part 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 false opening part. The protruding limit part and the false opening part of the groove can form a larger surface-to-surface contact, ensuring that the limit part and the false opening part are stable when they are hung, and are not easy to loosen, and the stop state can only be released when pushed by the charging plug.

[0023] Furthermore, the movable part located outside the charging port is provided with the limiting part, the false opening part corresponds to the limiting part, and the limiting part abuts against the false opening part. Another method of setting the limiting part is to set both the limiting part and the false opening part outside the charging port, which will not affect the structure of the charging port, and there is enough space to facilitate the setting of the limiting part and the false opening part.

[0024] Furthermore, the 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 limiting portion protruding from the movable part. The protruding direction of the 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 limiting portion can be directly pushed away from the erroneous opening portion to allow the limiting portion to enter the sliding opening.

[0025] Furthermore, the limiting portion protrudes in a direction perpendicular to the insertion direction of the charging plug, and the distance between the side wall of the movable member away from the charging port entrance and the side wall of the sliding opening away from the charging port entrance is greater than or equal to the distance the limiting portion moves out of the stop state. Another limiting portion structure can also ensure that when the movable member is pushed by the charging plug, the limiting portion can be separated from the mis-opening portion.

[0026] Furthermore, a first reset member is provided between the socket body and the movable member to keep the limit portion and the erroneous opening portion in abutment. The first reset member is mainly used to keep the 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 limit portion and the erroneous opening portion from releasing the stopped state due to vibration or accidental collision.

[0027] Furthermore, the first reset member is a spring sheet, one of the socket body and the movable member is fixedly connected to the first reset member, and the other is in contact with the first reset member. The spring sheet can accumulate elastic potential energy when the limit portion and the false opening portion are released from the stop, and the elastic potential energy is released when the charging plug is removed to ensure that the limit portion and the false opening portion can return to the stop state.

[0028] Furthermore, one of the movable part and the protective door is provided with a first slide groove, and the other is provided with a first sliding portion sliding in the first slide groove; one of the protective door and the socket body is provided with a second slide groove, and the other is provided with a second sliding portion sliding in the second slide groove, and the first slide groove and the second slide groove are not parallel. The movement speed ratio of the protective door and the movable part can be controlled by the two non-parallel slide grooves, so as to ensure that the movable part can drive the protective door to open in time after the charging plug is inserted according to the distance between the movable part and the protective door along the charging plug insertion direction.

[0039] A vehicle charging socket comprises a socket body 100, wherein the socket body 100 is provided with a charging port, wherein the charging port is provided with a plurality of wire insertion holes 120, wherein the charging port is used to dock with a charging plug, wherein a movable part 200 and a protective door 300 are provided in the socket body 100, wherein the movable part 200 is provided on the socket body 100 and is transmission-connected to the protective door 300; wherein the protective door 300 is slidingly provided in the socket body 100 to close or open the wire insertion hole 120 during the sliding process; wherein a limiting part 210 is provided on the movable part 200, wherein an erroneous opening part 130 is provided on the socket body 100, wherein the erroneous opening part 130 stops the limiting part 210, so that the protective door 300 is in a position of closing the wire insertion hole 120; wherein the movable part 200 moves toward the bottom of the charging port to release the stopping state of the limiting part 210 and the erroneous opening part 130, and then the movable part 200 moves in a direction away from the charging port to drive the protective door 300 to slide, thereby opening the wire insertion hole 120.

[0040] The protection door 300 is set in the socket body 100 in a sliding manner, and the protection door 300 opens more smoothly. The protection door 300 can cover the wire jack 120 on the socket body 100 to prevent foreign objects from being inserted into the wire jack 120 and avoid safety accidents. The opening and closing of the protection door 300 is driven by the movable part 200. When the charging plug is inserted into the charging port, the movable part 200 will be pushed to open the protection door 300, thereby not adding extra operating steps for customers. By providing a limiting portion 210 on the movable member 200 and an erroneous opening portion 130 on the socket body 100, the socket body 100 always remains in a stationary state when the charging plug is inserted or pulled out. Therefore, the limiting portion 210 can cooperate with the erroneous opening portion 130 more accurately to achieve a stopping state or release the stopping state. When the charging plug is inserted, the movable member 200 is pushed so that the movable member 200 first contacts the stopping state of the limiting portion 210 and the erroneous opening portion 130, and then the protective door 300 is driven by the movable member 200 to slide and open the wire jack 120. The wire jack 120 is unlocked and opened in turn by one movable member 200, so that the whole process is more continuous, and the unlocking and opening of the wire jack 120 will not be performed simultaneously, thereby avoiding the situation that the protective door 300 is stuck and cannot be opened. In addition, the above structure does not need to consider the positional relationship of the two movable members 200 as in the prior art, and the installation accuracy requirement is reduced, which is conducive to improving assembly efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] 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 wire jacks 120. The shape and specification of the charging port 110 are uniformly manufactured according to local standards. The number and position of the wire jacks 120 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.

[0046] 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 slidably arranged in the socket body 100. The movable part 200 is also slidably arranged in the socket body 100. The wire jack 120 is closed or opened during the sliding process by the protective door 300. Since the protective door 300 needs to be driven to slide by the movable part 200 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.

[0047] The movable member 200 is provided with a limiting portion 210, and the socket body 100 is provided with an erroneous opening portion 130. The erroneous opening portion 130 stops the limiting portion 210. When the movable member 200 is not acted upon by the charging plug, the protective door 300 is always in a position to close the wire insertion hole 120, thereby preventing foreign matter from entering the wire insertion hole 120. When the charging plug is inserted into the charging port, the charging plug pushes the movable member 200 to move, causing the movable member 200 to move in the same direction as the charging plug is inserted into the charging port. This displacement causes the limiting portion 210 to disengage from the erroneous opening portion 130, thereby realizing that the movable member 200 moves to release the stopping state of the limiting portion 210 and the erroneous opening portion 130. Then, as the charging plug continues to be inserted into the charging port, the movable member 200 will be squeezed out of the charging port, causing the movable member 200 to enter the socket body 100, thereby driving the protective door 300 to slide through the movement of the movable member 200, opening the wire insertion hole 120, allowing the charging plug to dock with the wire insertion hole 120, and realizing electrical connection between the two.

[0048] Furthermore, a sliding opening 111 is provided on the side wall of the charging port. The sliding opening 111 is mainly used to allow the movable part 200 to partially extend into the charging port. A driving end 220 extending into the charging port is provided on the movable part 200 so as to push the movable part 200 to move when the charging plug is inserted into the charging port. By pushing the driving end 220 through the charging plug, the limiting part 210 can be disengaged from the mistaken opening part 130, thereby releasing the blocking state.

[0049] The positions of the limit portion 210 and the mis-opening portion 130 include but are not limited to the following two:

[0050] One is to set the limiting portion 210 on the driving end 220, and the false opening portion 130 is located on the charging port next to the slide 111, the limiting portion 210 abuts against the false opening portion 130 in the direction away from the center of the charging port, the false opening portion 130 can be directly the inner wall of the charging port next to the slide 111, and the limiting portion 210 is directly pressed on the inner wall of the charging port, and due to the abutment relationship between the limiting portion 210 and the false opening portion 130, after the charging plug contacts the driving end 220, the driving end 220 cannot be pushed out of the charging port from the slide 111, but can only be pushed to the depth of the charging port, but it is such a push that can cause the limiting portion 210 and the false opening portion 130 to disengage and release the blocking state.

[0051] Furthermore, the limiting portion 210 is arranged on the side wall of the driving end 220 and protrudes from the side wall of the driving end 220, and a groove is opened on the side wall of the charging port next to the sliding opening 111 to form the false opening portion 130, that is, a concave-convex fit is formed, so that the limiting portion 210 and the false opening portion 130 can form a more stable stop state, and will not easily contact the stop when subjected to external vibration or accidental touch.

[0052] Another method is to set the limiting part 210 on the movable part 200 outside the charging port, and set the false opening part 130 on the socket body 100 at a position corresponding to the movable part 200. Generally, the limiting part 210 is protruding, so that there is a larger setting space outside the charging port, which can facilitate the arrangement of the limiting part 210 and the false opening part 130, so that the limiting part 210 and the false opening part 130 are more stable in the stopped state.

[0053] There are two directions in which the limiting portion 210 protrudes, namely, protruding toward the direction of the charging port entrance 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 blocking state of the limiting portion 210 and the incorrectly opened portion 130.

[0054] For the limiting portion 210 protruding toward the charging port entrance, because sufficient distance must be reserved for the limiting portion 210 and the false opening portion 130 to be able to disengage, the distance between the side wall of the movable part 200 away from the charging port entrance and the side wall of the sliding opening 111 away from the charging port entrance is ≥ the distance of the limiting portion 210 protruding the movable part 200; and for the limiting portion 210 protruding in a direction perpendicular to the charging plug insertion direction, the distance between the side wall of the movable part 200 away from the charging port entrance and the side wall of the sliding opening 111 away from the charging port entrance is ≥ the distance the limiting portion 210 moves on the false opening portion 130 when the limiting portion 210 is out of the stop state.

[0055] For the sliding structure of the protection door 300, one of the movable part 200 and the protection door 300 is provided with a first slide groove 230, and the other is provided with a first sliding part 310 sliding in the first slide; one of the protection door 300 and the socket body 100 is provided with a second slide groove 150, and the other is provided with a second sliding part 320 sliding in the second slide groove 150, and the first slide groove 230 and the second slide groove 150 are not parallel. In this embodiment, in order to reduce the size of the protection door 300 and allow the protection door 300 to slide more smoothly, the first sliding part 310 and the second sliding part 320 are both arranged on the protection door 300, and the first slide groove 230 and the second slide groove 150 are not parallel in order to allow the protection door 300 to have a larger movement stroke when the movable part 200 moves a smaller distance, so that the protection door 300 can be fully opened.

[0056] A first reset member 140 is provided between the socket body 100 and the movable member 200. The first reset member 140 is used to keep the limiting portion 210 and the mis-opening portion 130 in abutment state to prevent the movable member 200 from accidentally contacting the stop state. The first reset member 140 of this embodiment is a spring sheet, one end of which is fixedly connected to the socket body 100, and the other end of the spring sheet 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 140 is opposite to the direction in which the movable member 200 moves to release the stop state.

[0057] In addition, the movable member 200 is also connected to a second reset member 180. After the charging plug is removed, the movable member 200 is pushed back to its original position, allowing the driving end 220 to extend into the charging port, while driving the protective door 300 to close. The second reset member 180 is located between the socket body 100 outside the charging port and the movable member 200. When the charging plug is inserted into the charging port, the movable member 200 moves to accumulate elastic potential energy in the second reset member 180. When the charging plug is unplugged, the elastic potential energy of the second reset member 180 is released, driving the movable member 200 to return to its initial position, not only causing the protective door 300 to close the wire jack 120, but also causing the mis-opening portion 130 and the limiting portion 210 to run to a stop state.

[0058] The second reset member 180 generally adopts a compression spring. The socket body 100 and the movable member 200 are both provided with a positioning member for fixing the second reset member 180. The positioning member includes a positioning groove 160 and / or a positioning rod 170. In this embodiment, both the positioning groove 160 and the positioning rod 170 are used. The end of the second reset member 180 is inserted into the positioning groove 160, the positioning rod 170 is arranged in the positioning groove 160, and the positioning rod 170 extends into the second reset member 180. In this way, the two ends of the second reset member 180 are fixed to ensure that the second reset member 180 can play an expected role and drive the movable member 200 to reset after the charging plug is unplugged.

[0059] In this embodiment, there are two protective doors 300, which are respectively located on the left and right sides symmetrically of the vertical center line of the charging port. The movable part 200 is also symmetrically arranged about the vertical center line of the charging port. The left and right sides of the movable part 200 are respectively provided with first slide grooves 230 corresponding to the protective doors 300. The two protective doors 300 are arranged in parallel and located between the movable part 200 and the socket body 100. The protective door 300 is provided with a first sliding part 310 on the outward end surface. The first sliding part 310 extends into the first slide groove 230. In the initial state, there is a gap between the protective door 300 and the movable part 200, so that when the limit part 210 releases the stop state, the movable part 200 has enough space to move. A second slide groove 150 is provided on the surface of the socket body 100 corresponding to the protective door 300, and a second sliding part 320 is provided on the corresponding protective door 300 to extend into the second slide groove 150. The driving end 220 of the movable part 200 extending into the charging port is provided with an inclined surface. When the charging plug is inserted into the charging port, the end face of the charging plug abuts against the inclined surface on the driving end 220, but the downward thrust generated will be offset by the abutment between the limiting portion 210 and the false opening portion 130. Therefore, when the charging plug moves into the charging port, the movable part 200 will also first follow the charging plug to penetrate into the charging port. As the limiting portion 210 moves, the limiting portion 210 will also disengage from the false opening portion 130 and release the blocking state; thereafter, due to the downward force of the charging plug on the movable part 200, the movable part 200 will be squeezed out of the charging port, that is, the movable part 200 will move in a direction away from the center of the charging port, and at the same time will drive the protective door 300 to move outward, open the wire jack 120, and the charging plug is inserted into the wire jack 120.

[0060] After charging is completed, the charging plug is unplugged from the charging port, and the movable member 200 moves toward the center of the charging port under the action of the second reset member 180. At this time, the movable member 200 will also drive the protective door 300 to close the wire jack 120; the side wall of the movable member or the front end of the limiting portion 210 abuts against the side wall of the sliding opening 111, and the action of the first reset member 140 will not cause the movable member 200 to move toward the entrance of the charging port; when the second reset member 180 pushes the movable member 200 into place toward the center of the charging port, the limiting portion 210 passes over the false opening portion 130, and when it is pushed by the first reset member 140, it will push the movable member 200 toward the entrance of the charging port, so that the limiting portion 210 abuts against the false opening portion 130 and enters a stop state.

[0061] Through the scheme of this embodiment, the protective door 300 is used to protect the wire jack 120, and foreign objects are prevented from contacting the wire jack 120 when the charging plug is not inserted into the charging port; only when the charging plug is inserted, can the movable member 200 be pushed to move along the axial direction of the charging port, and when the stop state of the limit part 210 and the false opening part 130 is released, under the push of the charging plug, the movable member 200 can be changed to move away from the center of the charging port, and drive the protective door 300 to slide, so that the wire jack 120 is opened. When the charging plug is unplugged, under the sequential action of the second reset member 180 and the first reset member 140, the movable member 200 first moves toward the center of the charging port to make the protective door 300 close the wire jack 120, and then moves along the axial direction of the charging port toward the entrance of the charging port, so that the limit part 210 and the false opening part 130 are in a stop state. The purpose of stopping and controlling the opening and closing of the protective door 300 is achieved by moving a component of the movable part 200, and the stop and the opening and closing of the protective door 300 are performed in a sequential order, and even if there is an assembly error, it will not affect the overlap of the two sequences, thereby ensuring that the protective door 300 can be opened and closed normally and has the function of preventing accidental opening.

[0062] 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.
