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, the left and right sides of the movable seat are respectively provided with slide rails to cooperate with the rotating shaft on the door cover. The movable seat needs to move a long distance to control the door cover to open, and the movable seat is provided with a relatively complex slide rail structure, which is also easy to cause the rotating shaft to get stuck when sliding in the slide rail. In addition, 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, which still poses certain safety hazards. Utility Model Content

[0005] The utility model aims to provide a vehicle charging socket, which can effectively solve the problem that the movable seat of the existing charging pile socket needs to move a long distance to drive two protective doors.

[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, the socket body being provided with a charging port, the charging port being provided with a plurality of wire jacks, the charging port being used for docking a charging plug, the socket body being provided with a sliding member and a protective door, the protective door comprising two door bodies arranged crosswise, the same ends of the two door bodies being rotatably connected to the socket body, and the wire jacks being opened or closed during the rotation of the protective door; the sliding member being provided on the socket body and being transmission-connected to the intersection of the two door bodies;

[0008] Therefore, a flip piece is also provided on the socket body, and an error-opening portion is provided on the flip piece, and a limiting portion is provided on the protection door. The error-opening portion stops the limiting portion, so that the protection door is in a closed wire insertion hole position; the flip piece rotates to release the stopping state of the error-opening portion and the limiting portion, and then the sliding piece drives the protection door to slide to open the wire insertion hole.

[0009] In the above-mentioned vehicle charging socket, each door body is provided with a slide groove at the intersection with another door body, and the sliding member is provided with a sliding part that is inserted into the two slide grooves at the same time, and the sliding part acts on the slide groove to drive the two door bodies to rotate synchronously.

[0010] In the above-mentioned vehicle charging socket, the door body includes a shielding portion and a connecting portion, the connecting portion is rotatably connected to the socket body, and the connecting portion and the shielding portion are respectively located on both sides of the intersection of the door body.

[0011] In the above vehicle charging socket, the distance from the connecting portion to the intersection of the door body is less than the distance from the shielding portion to the intersection of the door body.

[0012] In the above-mentioned vehicle charging socket, an insertion opening is provided on the side wall of the charging port, and the shielding portion extends into the charging port through the insertion opening.

[0013] In the above-mentioned vehicle charging socket, the door body further includes an abutment portion, and when the protective door closes the wire insertion hole, the abutment portion abuts against the outer wall of the charging port next to the insertion port.

[0014] In the above-mentioned vehicle charging socket, the limiting portion is a limiting groove or a limiting hole, the erroneous opening portion is inserted into the limiting portion, and the flip member rotates to make the erroneous opening portion disengage from the limiting groove or the limiting hole, thereby releasing the blocking state.

[0015] In the above-mentioned vehicle charging socket, the false opening portion is a first blocking block arranged on the flip member, and the limiting portion is a second blocking block arranged on the protective door. Along the sliding direction of the protective door, the first blocking block stops on the sliding path of the second blocking block.

[0016] In the above-mentioned vehicle charging socket, the flip member is further provided with a first driving end, the first driving end extends into the charging port, and the first driving end drives the flip member to rotate when the charging plug is inserted.

[0017] In the above-mentioned vehicle charging socket, the sliding member is provided with a second driving end extending into the charging port. Along the direction in which the charging plug is inserted into the charging port, the second driving end is located downstream of the first driving end. The second driving end is pressed into the socket body when the charging plug is inserted. A reset member is also provided between the sliding member and the socket body. After the charging plug is pulled out, the reset member pushes the sliding member to return to its initial position.

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

[0019] The sliding member is connected to the intersection of the two door bodies through transmission, which solves the problem that the existing charging pile socket movable seat needs to move a long distance to drive the two protective doors. In this solution, the same end of the two door bodies is connected to the socket body for rotation, and the sliding member is arranged on the socket body and is connected to the intersection of the two door bodies for transmission. The sliding member can control the two door bodies to open a large angle relative to each other by only moving a small distance, thereby realizing the sliding member to control the door body to open or close the wire jack with a small displacement, which is conducive to reducing the volume of the socket. A flip member is also provided in this solution. Through the stopping effect of the mis-opening part on the flip member and the upper limit part of the protective door, the stopping state cannot be released when the flip member is not triggered to rotate. If there is a foreign object or the protective door is directly toggled, the protective door cannot be opened, which improves the safety of the protective door. Only when the charging plug is inserted into the charging port, the flip member is driven to rotate to release the stopping state, and then the sliding member is pushed to move to drive the protective door to slide, can the wire jack be opened, which greatly improves the safety of the protective door.

[0020] Furthermore, each door body is provided with a slide groove at the intersection with the other door body, and the sliding member is provided with a sliding part that is inserted into the two slide grooves at the same time, and the sliding part acts on the slide groove to drive the two door bodies to rotate synchronously. The sliding part passes through the two slide grooves, and when the sliding member slides, the two door bodies are driven to rotate synchronously, so that the two door bodies can open or close the wire jack synchronously. Since only one sliding part is provided on the sliding member, the structure of the sliding member is simplified, and the sliding part can be directly inserted into the slide groove during assembly, without considering the need to align the sliding part with a specific position of the slide groove, so that the installation steps are simplified.

[0021] Furthermore, the door body includes a shielding portion and a connecting portion, the connecting portion is rotatably connected to the socket body, and the connecting portion and the shielding portion are respectively located on both sides of the intersection of the door bodies. The connecting portion and the shielding portion are respectively arranged on both sides of the intersection of the door bodies, and when the sliding member is pushed toward the connecting portion, the shielding portions of the two door bodies will separate to achieve the purpose of opening the wire insertion hole, so that the purpose of pushing the sliding member toward the connecting portion to open the wire insertion hole can be achieved without adding other transmission structures.

[0022] Furthermore, the distance between the connection part and the door intersection is less than the distance between the shielding part and the door intersection. The sliding member connected to the door intersection only needs to move a short distance to make the shielding part swing a large amplitude, so that the shielding part can quickly open the wire insertion hole.

[0023] Furthermore, an insertion opening is provided on the side wall of the charging port, and the shielding part extends into the charging port through the insertion opening. The insertion opening is provided on the side wall so that the shielding part can be withdrawn from the charging port after opening the wire insertion hole, and will not block the insertion of the charging plug.

[0024] Furthermore, the door body also includes an abutment portion, and when the protective door closes the wire insertion hole, the abutment portion abuts against the outer wall of the charging port next to the insertion port. The abutment portion controls the position of the shielding portion extending into the charging port, so that the shielding portion can stay in the correct position to shield the wire insertion hole.

[0025] Furthermore, the limiting portion is a limiting groove or a limiting hole, the erroneous opening portion is inserted into the limiting portion, and the flip member rotates to make the erroneous opening portion disengage from the limiting groove or the limiting hole, thereby releasing the blocking state. The limiting groove or the limiting hole cooperates with the erroneous opening portion to limit the erroneous opening portion in multiple directions, thereby minimizing the shaking of the protective door in the blocking state.

[0026] Furthermore, the mis-opening part is a first blocking block provided on the flip member, and the limiting part is a second blocking block provided on the protective door, and along the sliding direction of the protective door, the first blocking block stops on the sliding path of the second blocking block. In another stopping structure of the mis-opening part and the limiting part, the two blocking blocks form a stopping state, which has a lower requirement on the matching accuracy of the flip member and the protective door, and is conducive to improving assembly efficiency.

[0027] Furthermore, the flip member is provided with a first driving end, the first driving end extends into the charging port, and the first driving end drives the flip member to rotate when the charging plug is inserted. The first driving end is used to drive the flip member to rotate when the charging plug is inserted into the charging port, so that the thrust of the charging plug can directly act on the flip member.

[0028] Furthermore, the sliding member is provided with a second driving end extending into the charging port, and along the direction in which the charging plug is inserted into the charging port, the second driving end is located downstream of the first driving end, and the second driving end is pressed into the socket body when the charging plug is inserted. A reset member is also provided between the sliding member and the socket body, and after the charging plug is pulled out, the reset member pushes the sliding member to return to its initial position. The second driving end presses the driving end into the socket body when the charging plug is inserted, thereby providing power to the sliding member through the second driving end, prompting the protective door to open. After the charging plug is pulled out of the charging port, the reset member can drive the sliding member to return to its initial position, and drive the protective door to close the wire jack. And along the direction in which the charging plug is inserted into the charging port, the second driving end is located downstream of the first driving end, ensuring that when the charging plug is inserted, the first driving end is first pushed to allow the mistaken opening part and the limit part to release the stop, and then the second driving end is pushed to allow the sliding member to drive the protective door to slide open the wire jack.

[0042] A vehicle charging socket, comprising a socket body 100, wherein the socket body 100 is provided with a charging port 110, wherein the charging port 110 is provided with a plurality of wire jacks 111, wherein the charging port 110 is used to connect with a charging plug, wherein the socket body 100 is provided with a sliding member 200 and a protective door 300, wherein the protective door 300 comprises two door bodies 310 arranged crosswise, wherein the same ends of the two door bodies 310 are both rotatably connected to the socket body 100, and the wire jacks 111 are opened or closed during the rotation of the protective door 300; wherein the sliding member 200 is arranged at The socket body 100 is transmission-connected to the intersection of the two door bodies 310; therefore, a flip member 400 is also provided on the socket body 100, and an erroneous opening portion 410 is provided on the flip member 400, and a limiting portion 320 is provided on the protection door 300, and the erroneous opening portion 410 stops the limiting portion 320, so that the protection door 300 is in a position to close the wire insertion hole 111; the flip member 400 rotates to release the stopping state of the erroneous opening portion 410 and the limiting portion 320, and then the sliding member 200 drives the protection door 300 to slide and open the wire insertion hole 111.

[0043] The existing charging pile socket movable seat drives the two protective doors 300 to move a long distance by means of the sliding member 200, which is connected to the intersection of the two door bodies 310. In this solution, the same end of the two door bodies 310 is rotatably connected to the socket body 100, and the sliding member 200 is arranged on the socket body 100 and is connected to the intersection of the two door bodies 310. The sliding member 200 can control the two door bodies 310 to open at a larger angle relative to each other by only moving a small distance, thereby realizing the sliding member 200 to control the door body 310 to open or close the wire jack 111 with a small displacement, which is conducive to reducing the volume of the socket. A flip member 400 is also provided in the present solution. Through the stopping effect of the false opening part 410 on the flip member 400 and the upper limit part 320 of the protection door 300, the stopping state cannot be released when the flip member 400 is not triggered to rotate. If there is a foreign object or the protection door 300 is directly pushed, the protection door 300 cannot be opened, thereby improving the safety of the protection door 300. Only when the charging plug is inserted into the charging port 110, the flip member 400 is driven to rotate to release the stopping state, and then the sliding member 200 is pushed to move to drive the protection door 300 to slide, can the wire jack 111 be opened, thereby greatly improving the safety of the protection door 300.

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 7 This is an embodiment of a vehicle charging socket of the utility model, which includes a socket body 100, on which a charging port 110 is provided, and a plurality of wire jacks 111 are provided in the charging port 110. The shape and specification of the charging port 110 are uniformly manufactured according to local standards, and the number and position of the wire jacks 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] A sliding member 200 and a protective door 300 are provided in the socket body 100. The main function of the sliding member 200 is to drive the protective door 300 to move and realize the opening and closing of the protective door 300. The sliding member 200 can be a slider, a slide plate or a slide rod. The sliding member 200 is slidably set on the socket body 100 and is transmission-connected to the protective door 300. The protective door 300 includes two cross-set door bodies 310. The sliding member 200 is connected at the intersection of the two door bodies 310, and can synchronously drive the two door bodies 310 to rotate, thereby opening or closing the wire jack 111 during the rotation of the protective door 300.

[0050] In order to prevent the protection door 300 from being directly opened by external force, a flip member 400 is provided in the socket body 100, and an incorrect opening portion 410 is provided on the flip member 400. A limiting portion 320 is provided on the protection door 300. The incorrect opening portion 410 stops the limiting portion 320, so that the protection door 300 is in a position to close the wire jack 111. That is, when external force directly acts on the protection door 300, the protection door 300 will be stopped by the flip member 400 and cannot be opened. Only when the flip member 400 rotates to release the stopping state of the incorrect opening portion 410 and the limiting portion 320, can the sliding member 200 drive the protection door 300 to slide, open the wire jack 111, and realize the electrical connection between the charging plug and the wire jack 111.

[0051] Furthermore, each door body 310 is provided with a slide groove 330 at the intersection with another door body 310. The slide groove 330 is a straight groove. The sliding member 200 is provided with a sliding portion 210 that is inserted into the two slide grooves 330 at the same time. The sliding portion 210 can be a slide bar or a slider. When the sliding member 200 slides, the sliding portion 210 acts on the slide groove 330 to drive the two door bodies 310 to rotate synchronously. Generally, the sliding member 200 is driven by the charging plug to slide in a straight line away from the center of the charging port 110, while the door body 310 has a swinging motion trajectory. The problem of inconsistent motion trajectories of the sliding member 200 and the protective door 300 can be solved by the slide groove 330, and the purpose of the sliding member 200 driving the protective door 300 to move can be smoothly achieved.

[0052] The lower ends of the two door bodies 310 at the intersection are the connecting parts 350, which are rotatably connected to the socket body 100, and a rotation hole is provided on the connecting part 350, and a second rotating shaft 160 is provided on the socket body 100 to realize the rotatable connection between the door body 310 and the socket body 100. The door body 310 includes a connecting part 350 and a shielding part 340, and the shielding part 340 is mainly used to shield the wire insertion hole 111. The connecting part 350 and the shielding part 340 are respectively located on both sides of the intersection of the door bodies 310, so that when the sliding member 200 moves away from the center of the charging port 110, the shielding parts 340 of the two door bodies 310 can be naturally pushed to open the wire insertion hole 111, which conforms to the movement trajectory of the sliding member 200, and there is no need to add other components to adjust the opening direction of the shielding part 340. The distance between the connecting portion 350 and the intersection of the door body 310 is less than the distance between the shielding portion 340 and the intersection of the door body 310, that is, the intersection of the two door bodies 310 is as close to the connecting portion 350 as possible, so that when the sliding member 200 pushes the door body 310 to move, the shielding portion 340 of the door body 310 can be driven with a smaller stroke to open the wire jack 111, thereby further reducing the volume of the socket body 100.

[0053] An insertion port 120 is provided on the side wall of the charging port 110, and the shielding portion 340 extends through the insertion port 120 into the charging port 110 to shield the wire insertion hole 111. The door body 310 also includes an abutment portion 360. When the protective door 300 closes the wire insertion hole 111, the abutment portion 360 abuts against the outer wall of the charging port 110 next to the insertion port 120, thereby limiting the position of the shielding portion 340 extending into the charging port 110, ensuring that the shielding portion 340 can stay in the correct position to shield the wire insertion hole 111. The two door bodies are mirror images on the left and right, and have the same structure. The shielding portion 340 is in the middle of the door body 310, the upper end of the shielding portion 340 is the limiting portion 320, the lower end of the shielding portion 340 is the connecting portion 350, and the abutment portion 360 is connected to the shielding portion 340.

[0054] The specific forms of the stop limiter 320 of the erroneous opening portion 410 include but are not limited to the following two:

[0055] One is that the limiting portion 320 is a limiting groove or a limiting hole, and the false opening portion 410 can be in the shape of a strip or a block. The false opening portion 410 is inserted into the limiting portion 320 and blocks the movement path of the limiting portion 320 when the protection door 300 swings, thereby playing a stopping role. Since the limiting portion 320 is a limiting groove or a limiting hole, when the false opening portion 410 and the limiting portion 320 are stopped, in addition to providing a block on the movement path of the limiting portion 320 when the protection door 300 is opened, it also has a limiting effect on the protection door 300 in other directions parallel to the swinging plane of the protection door 300. When the protection door 300 closes the wire jack 111, the false opening portion 410 can stabilize the relative position of the protection door 300 and prevent the protection door 300 from shaking along the radial direction of the charging port 110. Only when the flip member 400 rotates relative to the socket body 100, the false opening portion 410 will be separated from the movement path of the limiting portion 320, and the stop of the limiting portion 320 will be released, and the protection door 300 can be opened.

[0056] The other is that the false opening portion 410 is a first blocking block arranged on the flip member 400, and the limiting portion 320 is a second blocking block arranged on the protective door 300. Along the swinging direction of the protective door 300, the first blocking block blocks the swinging path of the second blocking block. In this scheme, the false opening portion 410 only serves to block the movement of the limiting portion 320 and does not limit the limiting portion 320 in other directions. However, the structure is relatively simple and the coordination requirements between the false opening portion 410 and the limiting portion 320 are also lower.

[0057] On the basis of the above scheme, the flip member 400 is rotatably arranged on the socket body 100, a rotating hole 430 is opened on the flip member 400, and a first rotating shaft 140 cooperating with the rotating hole 430 is provided on the socket body 100. A torsion spring 150 is also provided on the first rotating shaft 140. When the flip member 400 rotates, the torsion spring 150 accumulates elastic potential energy. When the charging plug is unplugged, the elastic potential energy of the torsion spring 150 is released, driving the flip member 400 to return to the initial position to stop the protection door 300.

[0058] In order to enable the flip member 400 to rotate when the charging plug is inserted into the charging port 110, a first driving end 420 is further provided on the flip member 400, and the first driving end 420 extends into the charging port 110, so that when the charging plug is inserted into the charging port 110, the end of the charging plug pushes the first driving end 420, driving the flip member 400 to rotate.

[0059] The sliding member 200 is provided with a second driving end 220 extending into the charging port 110. Along the direction in which the charging plug is inserted into the charging port 110, the second driving end 220 is located downstream of the first driving end 420. When the charging plug is inserted into the charging port 110, the charging plug first pushes the first driving end 420 to rotate, releases the blocking state of the false opening portion 410 and the limiting portion 320, and then pushes the second driving end 220, so that the sliding member 200 drives the protective door 300 to open the wire insertion hole 111. The end surface of the second driving end 220 in contact with the charging plug is an inclined surface. When the charging plug pushes the second driving end 220, the second driving end 220 is pressed into the socket body 100 through the action of the inclined surface, that is, the second driving end 220 is squeezed out of the charging port 110, pushing the sliding member 200 to slide.

[0060] The sliding member 200 is pushed to move when the charging plug is inserted, and drives the protective door 300 to open the wire jack 111. After the charging plug is unplugged, the protective door 300 is also required to automatically close the wire jack 111. Therefore, the sliding member 200 is connected with a reset member 500, and the reset member 500 is located between the socket body 100 outside the charging port 110 and the sliding member 200. When the charging plug is inserted into the charging port 110, the sliding member 200 moves to accumulate elastic potential energy. When the charging plug is unplugged, the elastic potential energy of the reset member 500 is released, driving the sliding member 200 to return to the initial position, not only making the protective door 300 close the wire jack 111, but also making the limiter 320 run to the stop position.

[0061] Furthermore, the reset member 500 generally adopts a compression spring, and the socket body 100 and the sliding member 200 are both provided with a positioning member 130 for fixing the reset member 500. The positioning member 130 includes a positioning groove and / or a positioning rod. In this embodiment, both the positioning groove and the positioning rod are used. The positioning rod is arranged in the positioning groove, and the end of the reset member 500 is inserted into the positioning groove, and the positioning rod is extended into the reset member 500. In this way, the two ends of the reset member 500 are fixed to ensure that the reset member 500 can play the expected role and drive the sliding member 200 to reset after the charging plug is unplugged.

[0062] When in use, when the charging plug is inserted into the charging port 110, it will first abut against the first driving end 420 of the flip member 400. As the charging plug is inserted, the flip member 400 will begin to rotate, and the false opening portion 410 will gradually break away from the limiting portion 320, releasing the blocking state between the false opening portion 410 and the limiting portion 320. At the same time, the first driving end 420 will also rotate out of the charging port 110, making room so that the charging plug can continue to extend into the charging port 110. The charging plug will then contact the second driving end 220 of the sliding member 200 and push the sliding member 200 to move outward, that is, push the second driving end 220 out of the charging port 110. At this time, the sliding portion 210 on the sliding member 200 interacts with the sliding groove 330 on the door body 310, and the sliding portion 210 pushes the two door bodies 310 to rotate, opening the wire jack 111, and the charging plug and the wire jack 111 are docked to achieve electrical connection. After charging is completed, as the charging plug is pulled out, the second driving end 220 loses the contact with the charging plug. Under the action of the reset member 500, the second driving end 220 will slide toward the center of the charging port 110, and at the same time drive the protection door 300 to swing and close the wire jack 111. The protection door 300 and the sliding member 200 return to their initial positions, and then the first driving end 420 also loses the contact with the charging plug. Under the action of the torsion spring 150, the flip member 400 rotates, the first driving end 420 enters the charging socket, the mistaken opening portion 410 also stops with the limit portion 320, and the flip member 400 returns to its initial position.

[0063] Through the vehicle charging socket of the above scheme, when a foreign object penetrates deeply into the charging port 110, if the protective door 300 is directly toggled, the protective door 300 will not be opened due to the stop of the incorrect opening part 410 and the limiting part 320, thereby preventing the foreign object from contacting the wire jack 111, avoiding damage to the wire jack 111 or the risk of electric shock. Only when the charging plug is inserted, the flip member 400 is first driven to rotate to release the stop, and then the sliding member 200 is driven to slide and drive the protective door 300 to rotate, can the wire jack 111 be opened, so that the charging plug can be connected to the wire jack 111, and two cross-arranged door bodies 310 are adopted, and the sliding member 200 pushes the intersection of the two door bodies 310 at the same time, so that the sliding member 200 can achieve a larger swing range of the shielding part 340 on the door body 310 with a smaller sliding distance, which is beneficial to reducing the volume of the entire socket body 100, and only one sliding part 210 on the sliding member 200 can drive the two door bodies 310 to swing at the same time, which also simplifies the structure of the sliding member 200 and improves assembly efficiency.

[0064] 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.
