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

[0018] By setting a swinging protection door to open or close the wire socket during the protection process, the problem of electric shock caused by the wire socket being easily touched by the current vehicle charging socket is solved. The protection door swings inside the socket body, and the protection door can be driven to swing to a large extent to open or close the wire socket through a very short movement stroke of the first sliding member. The protection door added in front of the wire socket provides safety protection for the wire socket, and the protection door can only be opened after the first sliding member is triggered to slide. In addition, a second sliding member is added to the socket body, and a false opening part is provided on the second sliding member, and a limiting part is provided on the protective door, and the false opening part stops the limiting part. In this way, if the protective door is directly pushed, the false opening part and the limiting part stop the protective door, which further improves the safety of the charging socket and cannot be easily opened. Only by pushing the second sliding member to slide, releasing the stopping state of the false opening part and the limiting part, and then pushing the first sliding member to slide to drive the protective door to swing, can the wire jack be opened to achieve the docking of the charging plug and the wire jack, and the sliding direction of the second sliding member is at an acute angle to the plugging and unplugging direction of the charging plug. When the charging plug is inserted into the charging port, the second sliding member will gradually move away from the center of the charging port, that is, when the stop state is released, space can be made for the charging plug to pass through, and the insertion of the charging plug is not hindered. The first sliding member can be provided to facilitate the opening of the protective door, and the second sliding member can be provided to prevent the false opening, so that the vehicle charging socket has higher safety protection and the function of preventing the false opening.

[0019] Furthermore, a blocking member is provided on the socket body, and the blocking member limits the second sliding member in a direction perpendicular to the insertion direction of the charging plug. Since the second sliding member gradually moves away from the center of the charging port when the charging plug is inserted, a blocking member is provided on the socket body to limit the second sliding member in a direction perpendicular to the insertion direction of the charging plug, so as to prevent the second sliding member from excessively moving in the vertical direction and being unable to return to the initial position.

[0020] Furthermore, the side wall of the charging port is provided with an insertion opening, the second sliding member includes a sliding member body, a first driving portion and a guide portion connected between the sliding member body and the first driving portion, the first driving portion passes through the insertion opening and extends into the charging port, and the guide portion is slidably arranged between the blocking member and the insertion opening. The first driving portion is used to abut against the charging plug, and the charging plug will abut against the first driving portion when inserted into the charging port, thereby pushing the second sliding member to slide, and the guide portion is slidably arranged between the blocking member and the insertion opening, which can limit the sliding direction of the second sliding member, and also to ensure that the second sliding member can return to its initial position after the charging plug is pulled out.

[0021] Furthermore, the guide portion includes a rear guide surface, and the rear guide surface is in sliding contact with the insertion port. By providing the rear guide surface, when the charging plug is inserted to push the second sliding member, the sliding direction of the second sliding member is limited by the sliding contact between the rear guide surface and the insertion port.

[0022] Furthermore, the guide portion includes a front guide surface, and the front guide surface is in sliding contact with the blocking member. By providing the front guide surface, when the charging plug is unplugged, the sliding direction of the second sliding member when returning to the initial position is limited by the sliding contact between the front guide surface and the blocking member.

[0023] Furthermore, a first restoring member is provided between the second sliding member and the socket body, and the first restoring member pushes the second sliding member to return to the initial position. The first restoring member provides a restoring force for the second sliding member when the charging plug is pulled out, and pushes the second sliding member back to the initial position.

[0024] Furthermore, one of the first sliding member and the protection door is provided with a straight slot, and the other is provided with a slide bar sliding in the slot. The straight slot makes it difficult for the slide bar to get stuck when sliding in the slot, so that the first sliding member drives the protection door to swing more smoothly.

[0025] Furthermore, the included angle between the sliding direction of the slide bar along the slide slot and the sliding direction of the first slide member is an obtuse angle. If the included angle is zero degrees, the protection door cannot be pushed open, and if the included angle is a right angle, the slide member will be stuck and cannot slide. When the included angle is an obtuse angle, the slide member can slide and the force of the slide bar and the side wall of the slide slot can generate a component force to push the protection door to rotate, so that the protection door can be rotated and opened when the slide member slides.

[0026] Furthermore, the limiting portion is a limiting groove or a limiting hole, the erroneous opening portion is inserted into the limiting portion, and the second sliding member slides 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.

[0027] Furthermore, a second reset member is provided between the first sliding member and the socket body, and the second reset member pushes the first sliding member to return to the initial position. When the charging plug is unplugged, the second reset member provides a restoring force for the first sliding member, so that the first sliding member can drive the protective door back to the initial position and close the wire jack.

[0052] See also Figures 1 to 10 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.

[0053] The socket body 100 is provided with a first sliding member 200 and a protective door 300. The main function of the first sliding member 200 is to drive the protective door 300 to swing, so as to open and close the protective door 300. The first sliding member 200 may be a slider or a slide plate or a slide bar 320. The first 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. One end of the protective door 300 is provided with a rotating hole and is rotatably connected to the rotating shaft. The first 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 first sliding member 200 when the charging plug is inserted, the first sliding member 200 needs to be arranged at the entrance of the charging port 110 closer to the protective door 300.

[0054] In order to prevent the protection door 300 from being accidentally opened, the socket body 100 is further provided with a second sliding member 400, the sliding direction of the second sliding member 400 is at an acute angle to the plugging and unplugging direction of the charging plug, the second sliding member 400 is provided with an erroneous opening portion 410, and the protection door 300 is provided with a limiting portion 310, the erroneous opening portion 410 stops the limiting portion 310, so that the protection door 300 is in a closed wire jack 120 position, that is, when the second sliding member 400 does not slide, the protection door 300 is in a stopped state, at this time, whether the first sliding member 200 is pushed or the protection door 300 is directly pushed, the protection door 300 cannot be opened, so that the protection door 300 is in a safer state. If the protection door 300 needs to be opened, the second sliding member 400 must be pushed first to release the stopping state of the second sliding member 400 and the protection door 300, and then the first sliding member 200 must be pushed, and the protection door 300 is driven to swing through the first sliding member 200, so as to open the wire jack 120.

[0055] The reason why the sliding direction of the second sliding member 400 is set to be an acute angle with the plugging and unplugging direction of the charging plug is that the second sliding member 400 needs to release the stop state when the charging plug is inserted, and the second sliding member 400 needs to be pushed by the charging plug, that is, the second sliding member 400 needs to contact the charging plug. However, after the stop state of the second sliding member 400 is released, the second sliding member 400 needs to make way and cannot hinder the charging plug from docking with the wire jack 120. To release the stop state, the second sliding member 400 needs to have a movement trajectory along the insertion direction of the charging plug, and needs to make way to allow the charging plug to pass. The second sliding member 400 needs to have a movement trajectory perpendicular to the insertion direction of the charging plug. The superposition of the two trajectories makes the sliding direction of the second sliding member 400 form an acute angle with the plugging and unplugging direction of the charging plug. The smaller the acute angle, the longer the sliding distance of the second sliding member 400 along the insertion direction of the charging plug, the longer the contact distance between the erroneous opening portion 410 and the limiting portion 310 in the stop state, and the longer the time for the second sliding member 400 to make way for the charging plug to pass.

[0056] Furthermore, a blocking member 500 is also provided on the socket body 100. The function of the blocking member 500 is to limit the second sliding member 400 in a direction perpendicular to the insertion direction of the charging plug. Since the charging plug is inserted into the charging port 110 at a too fast speed, the second sliding member 400 will generate a large inertia. If the second sliding member 400 slides too far in the direction perpendicular to the insertion direction of the charging plug, it may deviate from the original sliding trajectory, resulting in the second sliding member 400 being unable to return to the initial position.

[0057] The side wall of the charging port 110 is provided with an insertion opening 111. The insertion opening 111 is used to facilitate the second sliding member 400 to partially insert into the charging port 110 and contact the charging plug. On the other hand, the insertion opening 111 limits the sliding direction of the second sliding member 400 so that the second sliding member 400 can return to the initial position. The second sliding frame includes a sliding member body 420, a first driving part 430, and a guide part 440 connected between the sliding member body 420 and the first driving part 430. The first driving part 430 is responsible for inserting into the charging port 110. When the charging plug is inserted, it will abut against the first driving part 430, thereby pushing the second sliding member 400 to slide. In addition to playing a connecting role, the guide part 440 also slides and contacts with the blocking member 500 or the insertion opening 111 when the second sliding member 400 slides, thereby limiting the sliding direction of the second sliding member 400.

[0058] Furthermore, the guide portion 440 includes a front guide surface 442 and a rear guide surface 441. The front guide surface 442 faces the entrance of the charging port 110 and the angle between the front guide surface 442 and the charging plug insertion direction is consistent with the preset sliding angle of the second sliding member 400. The rear guide surface 441 faces away from the entrance of the charging socket and the angle between the front guide surface 441 and the charging plug insertion direction is consistent with the preset sliding angle of the second sliding member 400. The rear guide surface 441 is in sliding contact with the extension port 111. When the charging plug is inserted into the charging port 110, the sliding contact between the rear guide surface 441 and the extension port 111 will limit the sliding direction of the second sliding member 400. After the charging plug is pulled out, the front guide surface 442 of the second sliding member 400 is in sliding contact with the blocking member 500 or the front end of the extension port 111, limiting the sliding direction of the second sliding member 400 in the process of returning to the initial position. In order to facilitate the installation of the second sliding member 400 and reduce the difficulty of assembly, the gap between the rear guide surface 441 of the second sliding member 400 and the corresponding position of the insertion port 111 is increased in the present embodiment, so that the second sliding member 400 must first move a certain distance along the insertion direction of the charging plug, and the rear guide surface 441 is abutted against the insertion port 111 before the movement direction of the second sliding member 400 is changed, so that it slides at an acute angle to the insertion direction of the charging plug.

[0059] A first reset member 600 is provided between the second sliding member 400 and the socket body 100. The first reset member 600 can be an elastic component such as a compression spring. When the charging plug is inserted into the charging port 110, the second sliding member 400 slides and compresses the first reset member 600. When the charging plug is unplugged, the potential energy of the first reset member 600 is continuously released to push the second sliding member 400 to return to its initial position.

[0060] The first sliding member 200 mainly drives the protection door 300 to swing by the cooperation of the slide bar 320 and the slide groove 210. In this embodiment, the slide groove 210 is set on the first sliding member 200, and the slide bar 320 is set on the protection door 300. When the first sliding member 200 is squeezed by the charging plug and slides, the interaction between the slide groove 210 and the slide bar 320 is used to drive the protection door 300 to swing. The position where the slide bar 320 is set cannot coincide with the rotation axis of the protection door 300. The slide bar 320 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 first sliding member 200 slides the same distance. Of course, the slide groove 210 can also be set on the protection door 300, and the slide bar 320 can also be set on the first sliding member 200, but this will increase the area of ​​the protection door 300 for setting the slide groove 210. In the solution of the present utility model, the slide groove 210 will be arranged in a straight line, so that when the slide rod 320 slides along the slide groove 210, there is no turning, and the slide rod 320 will not be stuck in the slide groove 210, avoiding the situation that the protective door 300 will be stuck or even stuck when opening or closing. The first sliding member 200 is also provided with a second driving part 220, and the second driving part 220 passes through the side wall of the charging port 110 and extends into the charging port 110, so as to push the first sliding member 200 to slide when the charging plug is inserted into the charging port 110, and along the charging plug insertion direction, the second driving part 220 is located downstream of the first driving part 430, that is, after the charging plug is inserted into the charging port 110, it is necessary to push the first driving part 430 first, and then push the second driving part 220.

[0061] Furthermore, the angle between the length direction of the slide groove 210 and the sliding direction of the first sliding member 200 is an obtuse angle. When the first sliding member 200 slides downward, an outward thrust is generated on the slide rod 320, so that the protection door 300 rotates to open the wire jack 120, and the angle of the angle affects the speed at which the protection door 300 opens. When the angle is closer to a right angle, the protection door 300 opens faster and the opening angle is larger when the first sliding member 200 slides the same displacement.

[0062] 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, and 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 first sliding member 200 when the charging plug is inserted into the charging port 110 becomes smaller.

[0063] The specific forms of the stop limiter 310 of the erroneous opening portion 410 include but are not limited to the following two:

[0064] One is that the limiting portion 310 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 310 and blocks the movement path of the limiting portion 310 when the protective door 300 swings, thereby playing a stopping role. Since the limiting portion 310 is a limiting groove or a limiting hole, when the false opening portion 410 and the limiting portion 310 are stopped, in addition to providing a block on the movement path of the limiting portion 310 when the protective door 300 is opened, it also has a limiting effect on the protective door 300 in other directions parallel to the swinging plane of the protective door 300. When the protective door 300 closes the wire jack 120, the false opening portion 410 can stabilize the relative position of the protective door 300 and prevent the protective door 300 from shaking along the radial direction of the charging port 110. Only when the second sliding member 400 slides relative to the socket body 100, the false opening portion 410 will be separated from the movement path of the limiting portion 310, and the stop of the limiting portion 310 will be released, and the protection door 300 can be opened.

[0065] The other is that the false opening portion 410 is a first blocking block arranged on the second sliding member 400, and the limiting portion 310 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 310 and does not limit the limiting portion 310 in other directions. However, the structure is relatively simple and the coordination requirements between the false opening portion 410 and the limiting portion 310 are also lower.

[0066] The first sliding member 200 pushes the first sliding member 200 to move when the charging plug is inserted, and drives the protection door 300 to open the wire insertion hole 120. After the charging plug is unplugged, the protection door 300 is also required to automatically close the wire insertion hole 120. Therefore, the first sliding member 200 is connected with a second reset member 700, and the second reset member 700 is located between the socket body 100 outside the charging port 110 and the first sliding member 200. The second reset member 700 can be a compression spring or other elastic component. When the charging plug is inserted into the charging port 110, the first sliding member 200 moves to accumulate elastic potential energy for the second reset member 700; when the charging plug is unplugged, the elastic potential energy of the second reset member 700 is released, driving the first sliding member 200 to return to the initial position, not only making the protection door 300 close the wire insertion hole 120, but also making the limiter 310 run to the stop position.

[0067] Furthermore, the second reset member 700 generally adopts a compression spring, and the socket body 100 and the first sliding member 200 are both provided with a positioning member 130 for fixing the second reset member 700. 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 second reset member 700 is inserted into the positioning groove, and the positioning rod extends into the second reset member 700. In this way, the two ends of the second reset member 700 are fixed to ensure that the second reset member 700 can play the expected role and drive the first sliding member 200 to reset after the charging plug is unplugged.

[0068] When the charging plug is inserted into the charging port 110, it first abuts against the first driving portion 430 of the second sliding member 400, pushing the second sliding member 400 toward the charging port 110, and the rear guide surface 441 of the guide portion 440 on the second sliding member 400 contacts the insertion port 111, and the charging plug then applies a pushing force to the second sliding member 400. Figure 4 As shown, the rear guide surface 441 slides relative to the side wall of the insertion port 111, and the second sliding member 400 slides in the oblique upward direction, that is, the sliding direction of the second sliding member 400 forms an acute angle with the angle of insertion of the charging plug, until the first driving portion 430 of the second sliding member 400 completely withdraws from the charging port 110 or the first driving portion 430 no longer blocks the charging plug. At this time, the first reset member 600 connected to the second sliding member 400 is also compressed, and sufficient elastic potential energy is accumulated. And as the second sliding member 400 moves, the false opening portion 410 on the second sliding member 400 and the limiting portion 310 on the protective door 300 are released from the blocking state. The charging plug then abuts against the second driving portion 220 of the first sliding member 200. The second driving portion 220 is provided with a guide inclined surface 221. The charging plug contacts the guide inclined surface 221, which will push the first sliding member 200 to slide in a direction perpendicular to the insertion direction of the charging plug, that is, as shown in FIG. Figure 1 As described in the figure, the first sliding member 200 will move downward until the second driving part 220 also withdraws from the charging port 110 or the second driving part 220 makes enough space to break away from the abutment state with the front end of the charging plug, and the second reset member 700 also accumulates enough elastic potential energy. As the first sliding member 200 slides downward, the sliding groove 210 on the first sliding member 200 interacts with the sliding rod 320 on the protection door 300, driving the protection door 300 to swing, opening the wire plug, and the charging plug is connected to the wire jack 120 to achieve electrical connection.

[0069] After charging is completed, as the charging plug is pulled out, the first sliding member 200 loses the squeeze of the charging plug, the elastic potential energy of the second reset member 700 is released, the first sliding member 200 slides upward, driving the protection door 300 to close the wire jack 120, and the first sliding member 200 returns to the initial position; then the second sliding member 400 also loses the squeeze of the charging plug, and the first reset member 600 will push the second sliding member 400 to slide toward the entrance direction of the charging port 110, as shown in FIG. Figure 5 As shown, the front guide surface 442 of the guide portion 440 on the second sliding member 400 will abut against the blocking member 500 and slide along the front guide surface 442 relative to the blocking member 500, and the second sliding member 400 will slide obliquely downward and return to the initial position. At this time, the mis-opening portion 410 will be stopped by the limiting portion 310 to prevent the protective door 300 from being opened, so that the vehicle charging socket has higher safety protection and the function of preventing mis-opening.

[0070] 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.
