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 current charging piles, neither the plug nor the socket is equipped with a protective door, so it is easy for users to put their fingers into the socket, resulting in electric shock. In order to solve the above technical problems, China Patent Publication No. CN 108110503A discloses a technical solution entitled "A Highly Protective Charging Pile Plug", and its specification is attached. Figure 3 , Figure 4 The invention discloses a device with a clamping foot on the action part, and a clamping platform is provided on the flip part corresponding to the clamping foot. The clamping platform can rotate with the flip part. When the top corner is flipped into the insertion port, the clamping platform is clamped with the clamping foot, so that the installation arm cannot rotate. When the top corner is pressed and retracted into the side wall of the insertion port, the clamping platform rotates relative to the clamping foot and separates from it, and the installation arm can rotate. In this embodiment, the rotation of the installation arm is driven by a traction spring. Therefore, during use, if the top corner is not pressed into the side wall of the insertion port, the clamping platform is clamped with the clamping foot, and the installation arm cannot rotate. Although the wedge surface is pressed into the side wall of the insertion port, the installation arm still does not rotate. Only after the top corner is pressed into the side wall of the insertion port, the installation arm will rotate under the action of the traction spring, thereby opening the wire jack. The wire jack cannot be opened by only pressing the wedge surface or the top corner. In this way, two-level protection is achieved, which can effectively avoid opening the wire jack due to misoperation, and has strong safety.

[0004] It uses a traction spring to drive the sealing baffle to open. After long-term use, the traction spring may not be able to generate enough elastic force to pull the sealing baffle apart due to the influence of dust in the environment, resulting in failure to open the sealing baffle or partial opening, and the wire jack cannot be fully exposed. In addition, due to the large insertion port, the size of the sealing baffle is also large. Only one end of the sealing baffle is provided with a rotation control to rotate the sealing baffle, which has a high requirement on the front of the shaft. Long-term use can easily cause the shaft to deform, and the sealing baffle cannot be opened normally. Utility Model Content

[0005] The utility model aims to provide a vehicle charging socket, which can effectively solve the problems that the spring for pulling the sealing baffle to open in the existing charging pile plug is prone to failure, the sealing baffle opens in a fan shape, and the rotating shaft is prone to fatigue and damage.

[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 insertion holes, wherein the charging port is used to connect with a charging plug, wherein a sliding member and a protective door are provided in the socket body, wherein the sliding member is slidably 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 insertion holes during the sliding process;

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

[0009] In the above-mentioned vehicle charging socket, an insertion port is provided on the side wall of the charging port, and the protective door includes a shielding portion and a connecting portion, the shielding portion passes through the insertion port and extends into the charging port, the connecting portion is transmission-connected to the sliding member, and the connecting portion is slidingly connected to the socket body.

[0010] In the above-mentioned vehicle charging socket, the protection door further includes an abutment portion, and when the protection door closes the wire insertion hole, the abutment portion abuts against the outer wall of the charging port next to the insertion port.

[0011] In the above-mentioned vehicle charging socket, one of the sliding member and the protective door is provided with a first sliding groove, and the other is provided with a first sliding portion sliding in the first sliding groove; one of the protective door and the socket body is provided with a second sliding groove, and the other is provided with a second sliding portion sliding in the second sliding groove, and the first sliding groove and the second sliding groove are not parallel.

[0012] In the above-mentioned vehicle charging socket, there are two protective doors, which are symmetrically arranged along the vertical center line of the charging port.

[0013] 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 flipping portion rotates to make the erroneous opening portion disengage from the limiting groove or the limiting hole, thereby releasing the blocking state.

[0014] In the above-mentioned vehicle charging socket, the false opening portion is a first blocking block arranged on the flip portion, 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.

[0015] In the above vehicle charging socket, the flip part is rotatably arranged on the socket body, and a torsion spring is arranged between the flip part and the socket body to keep the erroneous opening part in a stop position.

[0016] In the above-mentioned vehicle charging socket, a first driving end is further provided on the flip part, and the first driving end extends into the charging port. The first driving end drives the flip part 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] By sliding the protective door on the socket body and directly driving the protective door to move by the sliding part, the problem that the spring pulling the sealing baffle to open in the existing charging pile plug is prone to failure, the sealing baffle opens in a fan shape, and the rotating shaft is prone to fatigue and damage can be effectively solved. The protective door is slidingly set on the socket body, and the moving distance of each position on the protective door is equal. The moving distance of the protective door can be accurately controlled to open all the wire jacks, avoiding the protective door from moving in vain and occupying too much space in the socket body. The sliding part directly drives the protective door and controls the movement of the protective door, so that the driving force of the sliding part is more directly transmitted to the protective door, abandoning the previous mode of spring drive, resulting in insufficient elastic force and unable to open the protective door, reducing the failure rate of the protective door. In addition, since the protective door is slidingly set on the socket body, its weight is no longer borne entirely by the rotating shaft as in the past. It can be slid on the socket body through a slider or as a whole, distributing the weight of the protective door to the socket body, so that it is not easy to produce local fatigue, ensuring that the protective door can operate for a long time. Through the stopping effect of the false opening part on the flip part and the upper limit part of the protective door, the stopping state cannot be released when the flip part is not triggered to rotate. If there is a foreign object or the protective door is directly pushed, the protective door cannot be opened, thereby improving the safety of the protective door. Only when the charging plug is inserted into the charging port to first drive the flip part to rotate to release the stopping state, and then push the sliding part to move and drive the protective door to slide, can the wire jack be opened, thereby greatly improving the safety of the protective door.

[0020] Furthermore, an insertion port is provided on the side wall of the charging port, and the protective door includes a shielding portion and a connecting portion, the shielding portion extends through the insertion port into the charging port, the connecting portion is transmission-connected to the sliding member, and the connecting portion is slidably connected to the socket body. The wire jack is shielded by the shielding portion extending from the insertion port into the charging port, while the connecting portion is located outside the charging port and is mainly responsible for transmitting power to drive the shielding portion to slide together, so as to prevent the transmission connection between the sliding member and the protective door from affecting the normal function of the shielding portion.

[0021] Furthermore, the protection door further includes an abutment portion, and when the protection 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 is used to control the depth of the shielding portion extending into the charging port, and the abutment between the abutment portion and the outer wall of the charging port next to the insertion port prevents the shielding portion from being inserted too deeply into the charging port, thereby reducing the ineffective movement stroke of the protection door when the wire insertion hole needs to be opened.

[0022] Furthermore, one of the sliding member and the protective door is provided with a first sliding groove, and the other is provided with a first sliding portion sliding in the first sliding groove; one of the protective door and the socket body is provided with a second sliding groove, and the other is provided with a second sliding portion sliding in the second sliding groove, and the first sliding groove and the second sliding groove are not parallel. The cooperation between the sliding groove and the sliding portion ensures that the protective door can slide along a predetermined trajectory, and the two non-parallel sliding grooves can be used to control the movement speed ratio of the protective door and the sliding member, so as to ensure that the sliding member can drive the protective door to open in time after the charging plug is inserted according to the distance between the sliding member and the protective door along the insertion direction of the charging plug.

[0023] Furthermore, there are two protection doors, which are symmetrically arranged along the vertical center line of the charging port. Setting two protection doors reduces the moving length of a single protection door without affecting the opening and closing of the wire jack, and the sliding member can slide a shorter distance to control the protection door to open the wire jack, thereby reducing the volume of the socket body.

[0024] Furthermore, the limiting part is a limiting groove or a limiting hole, the erroneous opening part is inserted into the limiting part, and the flip part rotates to make the erroneous opening part 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 part to limit the erroneous opening part in multiple directions, thereby minimizing the shaking of the protective door in the blocking state.

[0025] Furthermore, the mis-opening part is a first blocking block arranged on the flip part, and the limiting part is a second blocking block arranged 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 part and the protective door, and is conducive to improving assembly efficiency.

[0026] Furthermore, the flip part is rotatably arranged on the socket body, and a torsion spring is arranged between the flip part 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 part 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 part to the initial state, and the mis-opening part returns to the stop position with the limit part.

[0027] Furthermore, the flip part is provided with a first driving end, the first driving end extends into the charging port, and the first driving end drives the flip part to rotate when the charging plug is inserted. The first driving end is used to drive the flip part 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 part.

[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.

[0041] 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 connect with a charging plug, wherein a sliding member 200 and a protective door 300 are provided in the socket body 100, wherein the sliding member 200 is slidably provided on the socket body 100 and is transmission-connected to the protective door 300; wherein the protective door 300 is slidably provided in the socket body 100 so as to be closed or opened during the sliding process The wire insertion hole 120; therefore, the socket body 100 is also provided with a flipping portion 400, the flipping portion 400 is provided with an erroneous opening portion 410, the protection door 300 is provided with the limiting portion 310, the erroneous opening portion 410 stops the limiting portion 310, so that the protection door 300 is in a position to close the wire insertion hole 120; the flipping portion 400 rotates to release the stopping state of the erroneous opening portion 410 and the limiting portion 310, and then the sliding member 200 drives the protection door 300 to slide and open the wire insertion hole 120.

[0042] By slidingly setting the protection door 300 on the socket body 100, and directly driving the protection door 300 to move by the sliding member 200, the problem that the current sealing baffle opens in a fan shape, which easily causes the wire jack 120 to be unable to be fully opened or the far end occupies too much space, is solved. The protection door 300 is slidingly set on the socket body 100, and the moving distances of various positions on the protection door 300 are equal. The moving distance of the protection door 300 can be accurately controlled to open all the wire jacks 120, avoiding the protection door 300 moving in vain and occupying too much space in the socket body 100. The sliding member 200 directly drives the protection door 300 and controls the movement of the protection door 300, so that the driving force of the sliding member 200 is more directly transmitted to the protection door 300, abandoning the previous mode of spring drive, resulting in insufficient elastic force and the inability to open the protection door 300, and reducing the failure rate of the protection door 300. In addition, since the protection door 300 is slidably disposed on the socket body 100, its weight is no longer entirely borne by the rotating shaft as in the past. It can slide on the socket body 100 through a slider or as a whole, distributing the weight of the protection door 300 to the socket body 100, thereby not easily causing local fatigue, ensuring that the protection door 300 can operate for a long time. Through the blocking effect of the mis-opening portion 410 on the flip part 400 and the upper limit portion 310 of the protection door 300, the blocking state cannot be released when the flip part 400 is not triggered to rotate. If there is a foreign object or the protection door 300 is directly moved, the protection door 300 cannot be opened, which improves the safety of the protection door 300. Only when the charging plug is inserted into the charging port 110, the flip part 400 is driven to rotate to release the blocking 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, which greatly improves the safety of the protection door 300.

[0046] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] See also Figures 1 to 7 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.

[0048] 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, a slide plate or a slide bar. 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 slidably arranged in the socket body 100, and the sliding member 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 sliding member 200 when the charging plug is inserted, the sliding member 200 generally needs to be arranged closer to the entrance of the charging port 110 relative to the protective door 300.

[0049] The socket body 100 is further provided with a flip part 400, on which a false opening part 410 is provided, and on which a limiting part 310 is provided, the protective door 300, and the false opening part 410 stops the limiting part 310, so that when the flip part 400 does not move, the stopping state will be maintained, and in the stopping state, the protective door 300 will not be able to move and open, so that the protective door 300 is in a position to close the wire jack 120. Only when the flip part 400 rotates can the stopping state of the false opening part 410 and the limiting part 310 be released, and then the sliding member 200 drives the protective 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, an insertion port 130 is provided on the side wall of the charging port 110, and the protective door 300 includes a shielding portion 320 and a connecting portion 330. The shielding portion 320 is mainly used to shield the wire insertion hole 120. The shielding portion 320 extends into the charging port 110 through the insertion port 130. The connecting portion 330 is used for transmission connection with the sliding member 200 and sliding connection with the socket body 100, and is mainly used for transmitting power. Thus, the shielding portion 320 of the protective door 300 is separated from the transmission part and does not interfere with each other. Further, the protective door 300 also includes an abutting portion 340. When the protective door 300 closes the wire insertion hole 120, the abutting portion 340 abuts against the outer wall of the charging port 110 next to the insertion port 130. The abutting portion 340 can be used to control the length of the shielding portion 320 extending into the charging port 110. If the shielding portion 320 extends too deeply into the charging port 110 , the ineffective stroke when opening the shielding portion 320 will be too long, which will waste the space within the socket body and reduce the opening efficiency of the protective door 300 . Therefore, the abutment between the abutment portion 340 and the outer wall of the charging port 110 can achieve the purpose of accurately controlling the length of the shielding portion 320 extending into the charging port 110 .

[0051] For the transmission connection between the sliding member 200 and the protection door 300, the present embodiment adopts the matching form of a slide groove and a sliding part, a first slide groove 210 is provided on the sliding member 200, and a first sliding part 350 matching with the first slide groove 210 is provided on the protection door 300, and the first sliding part 350 can be a sliding block or a sliding rod. Of course, the first slide groove 210 can also be provided on the protection door 300, and the first sliding part 350 can be provided on the sliding member 200, but this will increase the area of ​​the protection door 300 and have a certain influence on the sliding of the sliding door. Therefore, the first sliding part 350 is provided on the protection door 300 to reduce the weight of the protection door 300, reduce the volume of the protection door 300, and make the protection door 300 slide more smoothly. Similarly, a second sliding portion 360 is arranged on the other side of the protective door 300, a second sliding groove 140 is arranged on the socket body 100, the first sliding portion 350 and the second sliding portion 360 are respectively arranged on the front and back end surfaces of the protective door 300, and the first sliding groove 210 and the second sliding groove 140 are not parallel, and the angle between the second sliding groove 140 and the vertical plane is smaller than the angle between the first sliding groove 210 and the vertical plane, so that the sliding speed and sliding distance of the protective door 300 are greater than the sliding member 200. When the driving end is completely pressed into the socket body 100, the protective door 300 also withdraws from the charging port 110, completing the step of opening the wire jack 120.

[0052] In order to reduce the size of a single protective door 300 and reduce the moving distance of the protective door 300, there are two protective doors 300 in this embodiment, and they are symmetrically arranged along the vertical center line of the charging port 110, so that the speed and stroke of opening and closing of the two protective doors 300 are consistent. The two protective doors 300 can effectively shorten the moving distance when opening the wire jack 120 and reduce the volume of the socket body 100. Correspondingly, two first sliding grooves 210 are also arranged symmetrically along the vertical center line of the charging port 110 on the sliding member 200 to ensure that the two protective doors 300 are opened or closed synchronously.

[0053] In order to achieve the stopping state of the false opening portion 410 and the limiting portion 310, the specific structures of the limiting portion 310 and the false opening portion 410 include but are not limited to the following structural forms:

[0054] One is that the limiting portion 310 is a limiting groove or a limiting hole, and the erroneous opening portion 410 is inserted into the limiting portion 310. The erroneous opening portion 410 is in a rod shape or a block shape. The limiting groove or the limiting hole can limit multiple dimensions of the erroneous opening portion 410 to prevent the protective door 300 from shaking. When the flip portion 400 rotates, the limiting portion 310 is disengaged from the erroneous opening portion 410, and the blocking state is released. Of course, the erroneous opening portion 410 can also be set as a limiting groove or a limiting hole, and the limiting portion 310 is inserted into the erroneous opening portion 410, which has the same effect as the above structure.

[0055] The other is that the false opening part 410 is a first blocking block provided on the flip part 400, and the position limiting part 310 is a second blocking block provided on the protection door 300, and the first blocking block stops on the sliding path of the second blocking block along the sliding direction of the protection door 300. The structure of the false opening part 410 and the position limiting part 310 has a relatively low assembly precision requirement, as long as the first blocking block can block on the moving path of the second blocking block to prevent the protection door 300 from opening, it is conducive to reducing the assembly difficulty and improving the assembly efficiency.

[0056] The flip part 400 is rotatably arranged on the socket body 100. A rotating hole is opened on the flip part 400. The socket body 100 is provided with a rotating shaft that cooperates with the rotating hole. A torsion spring 420 is also provided on the rotating shaft. When the flip part 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 part 400 to return to the initial position to stop the protection door 300.

[0057] In order to enable the flip part 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 part 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 to drive the flip part 400 to rotate.

[0058] 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 310, and then pushes the second driving end 220, so that the sliding member 200 drives the protection 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, so that the sliding member 200 slides.

[0059] 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 230, and the reset member 230 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 230; when the charging plug is unplugged, the elastic potential energy of the reset member 230 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 310 run to the stop state.

[0060] Furthermore, the reset member 230 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 230, and the positioning member includes a positioning groove 240 and / or a positioning rod 250. In this embodiment, both the positioning groove 240 and the positioning rod 250 are used, and the end of the reset member 230 is inserted into the positioning groove 240, and the positioning rod 250 is arranged in the positioning groove 240, and the positioning rod 250 extends into the reset member 230. In this way, the two ends of the reset member 230 are fixed to ensure that the reset member 230 can play the expected role and drive the sliding member 200 to reset after the charging plug is unplugged.

[0061] In this solution, a flip part 400 is provided on the socket body 100 above the charging port 110 or on the outer side wall of the charging port 110. The middle part of the flip part 400 is rotatably connected to the socket body 100 through a rotating shaft, and a torsion spring 420 is provided on the rotating shaft to help the flip part 400 return to the initial position after the external force is removed. The two ends of the flip part 400 are respectively provided with an erroneous opening part 410. In this embodiment, two protective doors 300 are also used, which are symmetrically arranged about the vertical center line of the charging port 110. The tops of the two protective doors 300 are respectively provided with a limit part 310 that stops the erroneous opening part 410. The two protection doors 300 are arranged between the sliding member 200 and the socket body 100. The front side of the protection door 300 is provided with a first sliding portion 350 which is slidably connected to the first sliding groove 210 on the sliding member 200. The back side of the protection door 300 is provided with a second sliding portion 360 which is slidably connected to the second sliding groove 140 on the socket body 100. The sliding member 200 is provided with a second driving end 220 which extends into the charging port 110.

[0062] When the charging plug is inserted into the charging port 110, it will first abut against the first driving end 430 of the flip part 400, causing the flip part 400 to rotate along the rotating shaft, and the false opening part 410 will disengage from the limiting part 310. The false opening part 410 and the limiting part 310 will release the blocking state. At the same time, the first driving end 430 will flip up to clear the position of the charging port 110, allowing the charging plug to continue to be inserted into the charging port 110. After the false opening part 410 and the limiting part 310 are released from the blocking state, the charging plug can abut against the second driving end 220 of the sliding member 200. The second driving end 220 is provided with a guiding inclined surface. When the charging plug is inserted into the charging port 110, the front end of the charging plug abuts against the second driving end 220 and squeezes the second driving end 220 out of the charging port 110. At this time, the second driving end 220 will move downward and drive the protective door 300 to slide. The protective door 300 opens the wire jack 120, and the charging plug and the wire jack 120 are connected to achieve electrical connection. After charging is completed, as the charging plug is pulled out, the reset member 230 pushes the sliding member 200 to return to the initial state, and the movement of the sliding member 200 also drives the protection door 300 to close the wire jack 120, and then the torsion spring 420 drives the flip part 400 to return to the initial state. When the flip part 400 returns to the initial state, the false opening part 410 stops the limiting part 310. Since the sliding member 200 is directly connected to the protection door 300 and drives the protection door 300 to open and close, and the protection door 300 is slidably arranged on the socket body 100, the sliding distances of various positions on the protection door 300 are equal, so that the opening and closing timing of the protection door 300 can be accurately controlled, so that the limiting part 310 on the protection door 300 can accurately cooperate with the false opening part 410 on the flip part 400 to achieve stopping.

[0063] 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.
