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 piles, there are no protective doors on the plugs and sockets, so users can easily put their fingers into the sockets, causing electric shock. In order to solve the above technical problems, Chinese patent publication number CN115395309A discloses a technical solution entitled "A new type of European standard charging socket with protective door to prevent electric shock". The specific implementation mode of the specification describes that "the anti-electric shock protection door assembly 7 includes an anti-electric shock protection door panel 701 fixed by a limiting guide column 403 and a sliding groove 702 arranged at the top of the anti-electric shock protection door panel 701. The upper end of the anti-electric shock protection door panel 701 is fixedly matched with the limiting guide column 403 to achieve rotation. The sliding groove 702 is L-shaped, and an upper limiting groove 703 is arranged at the upper end of the sliding groove 702, and a lower limiting groove 704 is arranged at the lower end. The sliding groove 702 cooperates with the sliding guide column 808 on the built-in limiting slider 802 to achieve sliding", that is, it adopts an L-shaped sliding groove, and a limiting groove is arranged at the lower end of the sliding groove, which makes the structure of the sliding groove too complicated, and the sliding guide column is easily stuck at each inflection point of the limiting groove, resulting in the protection door panel unable to open. Utility Model Content

[0004] The utility model aims to provide a vehicle charging socket, which can effectively solve the problem that the existing sliding guide column is easily stuck with the sliding groove, resulting in the protection door being unable to open.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] 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, one of the sliding member and the protective door being provided with a straight-shaped sliding groove, the other being provided with a sliding rod sliding in the sliding groove, the sliding member being slidably arranged on the socket body, the protective door being swingably arranged in the socket body, the sliding member driving the protective door to swing, and the protective door closing or opening the wire jacks during the swinging process;

[0007] 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.

[0008] In the above-mentioned vehicle charging socket, the included angle between the length direction of the sliding groove and the sliding direction of the sliding member is an obtuse angle.

[0009] In the above-mentioned vehicle charging socket, there are two protective doors, which are respectively located on both sides of the vertical center line of the charging port.

[0010] 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.

[0011] 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 swinging direction of the protective door, the first blocking block stops on the swinging path of the second blocking block.

[0012] In the above vehicle charging socket, the flip member is rotatably arranged on the socket body, and a torsion spring is arranged between the flip member and the socket body to keep the mistaken opening portion in a stop position.

[0013] 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.

[0014] 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.

[0015] In the above-mentioned vehicle charging socket, the sliding member is further provided with an abutment portion, the side wall of the charging port is provided with an opening for the second driving end to extend therein, and the limiting portion abuts against the outer side wall of the charging port next to the opening.

[0016] In the above vehicle charging socket, one end of the reset member abuts against the limit portion.

[0017] Compared with the prior art, the advantages of the utility model are:

[0018] By setting a straight groove and a sliding rod to cooperate, the problem that the current sliding guide column is easily stuck with the sliding groove, causing the protective door to be unable to open is solved. Since a straight groove is provided on one of the sliding member and the protective door, and a sliding rod sliding in the groove is provided on the other, there is no inflection point in the groove, and the sliding rod avoids getting stuck at the inflection point when sliding in the groove, so that the sliding member can smoothly drive the protective door to open when driven, allowing the charging gun to dock with the wire jack. 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 and drive the protective door to slide, can the wire jack be opened, which greatly improves the safety of the protective door.

[0019] Furthermore, the included angle between the length direction of the slide groove and the sliding direction of the sliding member is an obtuse angle. If the included angle is zero degrees, the protective door cannot be pushed open, and if the included angle is a right angle, the sliding member will be stuck and cannot slide. When the included angle is an obtuse angle, the sliding member can slide and the force of the slide rod and the side wall of the slide groove can generate a component force to push the protective door to rotate, so that the sliding member drives the protective door to rotate and open.

[0020] Furthermore, the protective door has two leaves, which are located on both sides of the vertical center line of the charging port. The two protective doors can shorten the length of the movement track when a single protective door is opened, reduce the volume of the socket body, and shorten the time it takes for the charging port to be fully opened. The two protective doors are located on both sides of the vertical center line and are independent of each other, making the movement track simpler.

[0021] 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.

[0022] 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 swinging direction of the protective door, the first blocking block stops on the swinging 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.

[0023] Furthermore, the flip member is rotatably arranged on the socket body, and a torsion spring is arranged between the flip member and the socket body to keep the mis-opening part in the stop position. Through the torsion spring, elastic potential energy is accumulated when the flip member is acted upon by the charging plug, and when the charging plug is pulled out, the torsion spring releases the elastic potential energy to restore the flip member to the initial state, and the mis-opening part returns to the stop position with the limit part.

[0024] 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.

[0025] 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.

[0026] Furthermore, the sliding member is provided with an abutment portion, and an opening is provided on the side wall of the charging port for the second driving end to extend therein, and the abutment portion abuts against the outer wall of the charging port next to the opening. The abutment portion can limit the length of the sliding member entering the charging port, thereby preventing the sliding member from extending into the charging port too long, causing the sliding member to abut and get stuck when the charging plug is inserted, and causing the charging plug to be unable to push the sliding member to slide.

[0027] Furthermore, one end of the reset member abuts against the abutment portion. Since the abutment portion abuts against the outer wall of the charging port, the cross-sectional area of ​​the abutment portion is slightly larger than the second driving end. Abutting one end of the reset member against the abutment portion allows the reset member and the sliding member to have a larger contact area, and the contact between the reset member and the sliding member is more stable.

[0039] 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 120, wherein the charging port 110 is used to dock with a charging plug, wherein a sliding member 200 and a protective door 300 are provided in the socket body 100, wherein one of the sliding member 200 and the protective door 300 is provided with a straight-line sliding groove 210, and the other is provided with a sliding rod 310 sliding in the sliding groove 210, wherein the sliding member 200 is slidably arranged on the socket body 100, and the protective door 300 is swingably arranged in the socket body 100, wherein the sliding member 200 drives the protective door 300 to swing, and the protective door 300 closes or opens the wire jack 120 during the swinging process;

[0040] Therefore, the socket body 100 is also provided with a flip member 400, the flip member 400 is provided with an erroneous opening portion 410, the protection door 300 is provided with a limiting portion 320, the erroneous opening portion 410 stops the limiting portion 320, so that the protection door 300 is in a position of closing the wire insertion hole 120; 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 120.

[0041] By providing a straight groove 210 and a slide bar 310 to cooperate, the problem that the current sliding guide column is easily stuck with the sliding groove, resulting in the protection door 300 being unable to open is solved. Since a straight groove 210 is provided on one of the sliding member 200 and the protection door 300, and a slide bar 310 sliding in the groove 210 is provided on the other, there is no inflection point in the groove 210, and the slide bar 310 avoids getting stuck at the inflection point when sliding in the groove 210, so that when the sliding member 200 is driven, the protection door 300 can be smoothly driven to open, allowing the charging gun to dock with the wire jack 120. 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 and drive the protection door 300 to slide, can the wire jack 120 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.

[0046] See also Figures 1 to 5 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.

[0047] The socket body 100 is provided with a sliding member 200 and a protective door 300. 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 or a slide plate or a slide bar 310. The sliding member 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 socket body 100 is provided with a rotating shaft 130. One end of the protective door 300 is provided with a rotating hole 330 and is rotatably connected to the rotating shaft 130. The sliding member 200 is slidably arranged in the socket body 100, and the wire jack 120 is closed or opened during the swinging process by the protective door 300. Since the protective door 300 needs to be driven to slide by the sliding member 200 when the charging plug is inserted, the sliding member 200 generally needs to be arranged at the entrance of the charging port 110 closer to the protective door 300.

[0048] The sliding member 200 mainly drives the protection door 300 to swing by the cooperation of the sliding rod 310 and the sliding groove 210. In this embodiment, the sliding groove 210 is set on the sliding member 200, and the sliding rod 310 is set on the protection door 300. When the sliding member 200 is squeezed by the charging plug and slides, the interaction between the sliding groove 210 and the sliding rod 310 is used to drive the protection door 300 to swing. The position where the sliding rod 310 is set cannot coincide with the rotation axis of the protection door 300. The sliding rod 310 needs to be a certain distance from the rotation axis of the protection door 300. The shorter the distance, the greater the swing amplitude of the protection door 300 when the sliding member 200 slides the same distance. Of course, the sliding groove 210 can also be set on the protection door 300, and the sliding rod 310 can also be set on the sliding member 200, but this will increase the area of ​​the protection door 300 for setting the sliding groove 210. In the solution of the utility model, the slide groove 210 will be set in a straight line shape, so that when the slide rod 310 slides along the slide groove 210, there is no turning, and the slide rod 310 will not be stuck in the slide groove 210, avoiding the protective door 300 from getting stuck or even stuck when opening or closing.

[0049] 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 120. 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 120, and realize the electrical connection between the charging plug and the wire jack 120.

[0050] Furthermore, the angle between the length direction of the slide groove 210 and the sliding direction of the sliding member 200 is an obtuse angle. When the sliding member 200 slides downward, an outward thrust is generated on the slide rod 310, so that the protective door 300 rotates to open the wire jack 120, and the angle of the angle affects the speed at which the protective door 300 opens. When the angle is closer to a right angle and the sliding member 200 slides the same displacement, the faster the protective door 300 opens and the larger the opening angle.

[0051] In this embodiment, there are two protection doors 300, which are respectively located on both sides of the vertical center line of the charging port 110. The vertical center line is perpendicular to the direction in which the charging plug is inserted into the charging port 110. The two protection doors 300 can shorten the opening range of the single protection door 300, thereby reducing the volume of the socket body 100, and the two protection doors 300 also reduce the strength requirements of the rotating shaft connecting the protection door 300 and the socket body 100. The area and weight of the single protection door 300 are reduced, and the resistance of pushing the sliding member 200 when the charging plug is inserted into the charging port 110 becomes smaller.

[0052] The specific forms of the stop limiter 320 of the erroneous opening portion 410 include but are not limited to the following two:

[0053] 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 120, 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.

[0054] 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.

[0055] On the basis of the above scheme, the flip member 400 is rotatably arranged on the socket body 100, a rotating hole is opened on the flip member 400, and a rotating shaft matching the rotating hole is provided on the socket body 100. A torsion spring 420 is also provided on the rotating shaft. When the flip member 400 rotates, the torsion spring 420 accumulates elastic potential energy. When the charging plug is unplugged, the elastic potential energy of the torsion spring 420 is released, driving the flip member 400 to return to the initial position to stop the protection door 300.

[0056] 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 430 is further provided on the flip member 400, and the first driving end 430 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 430, driving the flip member 400 to rotate.

[0057] 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 430. When the charging plug is inserted into the charging port 110, the charging plug first pushes the first driving end 430 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 jack 120. 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.

[0058] 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 120. After the charging plug is unplugged, the protective door 300 is also required to automatically close the wire jack 120. 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 of the reset member 500; 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 120, but also making the limiter 320 run to the stop position. In addition, when the elastic potential energy of the reset member 500 is released, the sliding member 200 may be pushed too close to the center of the charging port 110, which will result in the failure to push the sliding member 200 away from the charging port 110 when the charging plug is inserted. Therefore, it is necessary to limit the sliding of the sliding member 200 during reset. The sliding member 200 is provided with an abutting portion 230. The side wall of the charging port 110 is provided with an opening 111 for the second driving end 220 to extend therein, and the abutting portion 230 abuts against the outer wall of the charging port 110 next to the opening 111. The thickness of the abutting portion 230 is greater than the width of the opening 111. The thickness advantage of the abutting portion 230 is fully utilized to abut one end of the reset member 500 against the abutting portion 230, thereby expanding the contact area between the reset member 500 and the sliding member 200, reducing the deformation of the sliding member 200 at the contact position with the reset member 500, and making the reset member 500 and the sliding member 200 more firmly connected and not easy to slip off.

[0059] 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 for fixing the reset member 500, and the positioning member includes 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, and the positioning rod 150 is arranged in the positioning groove 140. The end of the reset member 500 is inserted into the positioning groove 140, and the positioning rod 150 extends 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.

[0060] When in use, when the charging plug is inserted into the charging port 110, it will first abut against the first driving end 430 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 disengage 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 430 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. Then the charging plug contacts the second driving end 220 of the sliding member 200 and pushes the sliding member 200 to move outward, that is, pushes the second driving end 220 out of the charging port 110. At this time, the sliding groove 210 on the sliding member 200 interacts with the sliding rod 310 on the protective door 300. The sliding rod 310 will slide along the length direction of the sliding groove 210, prompting the protective door 300 to start rotating, opening the wire jack 120, and the charging plug and the wire jack 120 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 120. The protection door 300 and the sliding member 200 return to their initial positions, and then the first driving end 430 also loses the contact with the charging plug. Under the action of the torsion spring 420, the flip member 400 rotates, the first driving end 430 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. Through the vehicle charging socket of the above scheme, when a foreign object penetrates deep into the charging port 110, if the protection door 300 is directly toggled, the protection door 300 will not be able to be opened due to the stop of the incorrect opening part 410 and the limit part 320, thereby preventing the foreign object from contacting the wire jack 120, avoiding damage to the wire jack 120 or the risk of electric shock. Only when the charging plug is inserted, the flip part 400 is driven to rotate to release the stop, and then the sliding part 200 is driven to slide and drive the protection door 300 to rotate, can the wire jack 120 be opened, so that the charging plug can be connected to the wire jack 120, and when the sliding part 200 drives the protection door 300 to open, a straight-line sliding groove 210 is provided on the sliding part 200 to ensure that the sliding rod 310 on the protection door 300 slides smoothly and is not easy to get stuck, so that the opening and closing of the entire protection door 300 can be carried out smoothly.
