[0003] In the related art, the protective door can be rotatably arranged, and the protective door has shielding parts corresponding to the N-pole socket, L-pole socket and E-pole socket respectively. The shielding part corresponding to the E-pole socket has a driving surface, and the driving surface is a straight inclined surface arranged at an angle to allow the ground pole pin to abut against the driving surface to realize the rotational drive of the protective door.

[0004] However, the protective door provided by the related art has at least the following disadvantages: when the latch drives the protective door, a large driving force is required, and the insertion stroke of the latch needs to be large enough to fully drive the protective door, which is not conducive to the lightweight design of the protective door. Summary of the Invention

These drawings and the accompanying description are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0079] In the description of the present invention, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific position, be constructed and operate in a specific position, and therefore should not be understood as limiting the present invention. For example, in the embodiment of the present invention, the position of the panel of the socket is defined as "up", and the position of the socket assembly is defined as "down".

[0080] The socket protection door provided by the related technology has at least the following disadvantages: when the E-pole pin drives the protection door, a large driving force is required, and it is easy to get stuck or the driving is not smooth, resulting in a jerky feel for the user. Moreover, the protection door can only be fully driven when the insertion stroke of the E-pole pin is large enough, which will cause the height of the protection door to be relatively large, which is not conducive to the lightweight design of the protection door and the socket.

[0081] In view of the technical problems existing in the related art, the embodiment of the present invention provides a socket protection door 100, as shown in the attached Figure 1 and attached Figure 2 As shown, the socket protection door 100 comprises a main body 10, an E-pole shielding portion 11, an L-pole shielding portion 12, and an N-pole shielding portion 13. The main body 10 is rotatably mounted on the socket. The E-pole shielding portions 11, L-pole shielding portions 12, and N-pole shielding portions 13 are connected to the circumference of the main body 10 and spaced apart along the circumference. The surface of the E-pole shielding portion 11 facing the socket has an E-pole driving surface 110 for driving the E-pole plug 001. The E-pole driving surface 110 is tilted in at least two different directions to facilitate rotation of the socket protection door 100 along a predetermined rotational path.

[0082] It should be noted that the "E-pole driving surface 110 is arranged obliquely along at least two different oblique directions" involved in the embodiment of the present invention not only includes an oblique arrangement relative to the plane where the driving direction of the pin is located, but also includes an oblique arrangement relative to the plane where the socket is located, thereby allowing the E-pole plug 001 to abut against the E-pole driving surface 110 and drive it to move when it is inserted downward from the socket of the socket, so that the socket protection door 100 rotates, thereby moving the socket protection door 100 from a position blocking the socket to a position exposing the socket.

[0083] The socket protection door 100 provided in an embodiment of the present invention improves the E-pole driving surface 110 of the E-pole shielding portion 11 so that it is tilted along at least two different tilt directions. That is to say, the E-pole driving surface 110 is a multi-directional composite tilted driving surface, so that when the E-pole pin 001 contacts it, it can generate a multi-directional friction coupling driving effect, which can better guide the rotation along the set rotation path, avoid the offset or jamming that may occur in a single direction drive, improve the driving smoothness, and reduce the driving force. Moreover, the multi-directional composite tilted driving surface design of the E-pole driving surface 110 is also conducive to reducing the insertion stroke of the E-pole pin 001, thereby shortening the height of the socket protection door 100 and the socket, and is conducive to the lightweight design of the socket.

[0084] In some examples, embodiments of the present invention provide a socket protection door 100, which includes: a main body 10, an E-pole shielding portion 11, an L-pole shielding portion 12 and an N-pole shielding portion 13. The surface of the E-pole shielding portion 11 facing the socket has an E-pole driving surface 110 for driving the E-pole pin 001. The E-pole driving surface 110 is tilted along two different tilt directions to promote the socket protection door 100 to rotate along a set rotation path.

[0085] Specifically, as attached Figure 3 -Attached Figure 4 As shown, the E-pole driving surface 110 is inclined along the first direction and forms a first angle α1 with the reference plane AA, wherein, in the embodiment of the present invention, the reference plane AA is parallel to the plane where the socket hole is located, the first direction is defined by the first end 1101 of the E-pole driving surface 110 close to the main body 10 and the second end 1102 of the E-pole driving surface 110 away from the main body 10, and the first end 1101 of the E-pole driving surface 110 is closer to the socket hole than the second end 1102 of the E-pole driving surface 110, that is, Figure 3 In the orientation shown, the first end 1101 of the E-pole drive surface 110 is located above the second end 1102 of the E-pole drive surface 110 .

[0086] The E-pole drive surface 110 is inclined along a first direction and forms a first angle α1 with the reference plane AA, so that the E-pole drive surface 110 forms a slope in the insertion direction of the E-pole plug 001. When the E-pole plug 001 is inserted, the end of the E-pole plug 001 contacts the E-pole drive surface 110 and generates a first axial force component (F1a) and a radial force component (F1b). The first axial force component (F1a) is along the insertion direction of the E-pole plug 001 (i.e., from top to bottom), and the radial force component (F1b) is along the radially inward direction of the main body 10 (i.e., from outside to inside). The first axial force component (F1a) and the radial force component (F1b) work together to convert the driving force applied by the E-pole plug 001 to the socket protection door 100 into a force consistent with the rotation direction of the socket protection door 100, prompting the main body 10 of the socket protection door 100 to rotate along a set path.

[0087] As attached Figure 3 and attached Figure 5 As shown, the E-pole driving surface 110 is inclined along the second direction and forms a second angle α2 with the reference plane AA, wherein the second direction is defined by the third end 1103 and the fourth end 1104 of the E-pole driving surface 110 distributed along the rotation direction of the main body 10, further combined with Figure 6 , the third end 1103 of the E-pole driving surface 110 is located downstream of the rotation path relative to the fourth end 1104 of the E-pole driving surface 110, and the third end 1103 of the E-pole driving surface 110 is closer to the socket above the fourth end 1104 of the E-pole driving surface 110, that is, Figure 3 In the orientation shown, the third end 1103 of the E-pole drive surface 110 is located above the fourth end 1104 of the E-pole drive surface 110 .

[0088] See also Figure 6 , the upstream and downstream of the rotation path are in a relative position relationship, and the downstream is farther away from the rotation starting point of the rotation path than the upstream.

[0089] The E-pole drive surface 110 is inclined along a second direction and forms a second angle α2 with the reference plane AA, which also enables the E-pole drive surface 110 to form a slope in the insertion direction of the E-pole plug 001. When the E-pole plug 001 is inserted, the end of the E-pole plug 001 contacts the E-pole drive surface 110 and generates a second axial force component (F2a) and a circumferential force component (F2c). The second axial force component (F2a) is along the insertion direction of the E-pole plug 001 (i.e., from top to bottom), and the circumferential force component (F2c) is along the circumferential direction of the main body 10 (i.e., the rotation direction of the main body 10). The second axial force component (F2a) and the circumferential force component (F2c) act synergistically, converting the driving force applied by the E-pole plug 001 to the socket protection door 100 into a force consistent with the rotation direction of the socket protection door 100, further promoting the rotation of the main body 10 of the socket protection door 100.

[0090] It can be seen that the embodiment of the present invention forms a three-dimensional driving surface by tilting the E-pole driving surface 110 in two different directions, thereby realizing multi-dimensional decomposition and synergistic effect of the driving force, so that the E-pole pin 001 is simultaneously subjected to the combined effects of axial thrust, circumferential rotational force, and tangential constraint resistance during the insertion process, thereby realizing efficient and smooth transmission of the driving force and allowing the E-pole pin 001 to complete circumferential rotational drive within a shorter axial stroke.

[0091] Furthermore, the E-pole driving surface 110 satisfies at least one of the following conditions: Figure 4 As shown, the surface of the E-pole driving surface 110 inclined along the first direction is called the first inclined surface 110a. From the first end 1101 to the second end 1102 of the E-pole driving surface 110, the first angle α1 formed by the first inclined surface 110a and the reference plane AA has an increasing trend. For example, the first angle α1 can increase in the range of 10°-60°.

[0092] As attached Figure 5 As shown, the surface of the E-pole driving surface 110 inclined along the second direction is called the second inclined surface 110b. From the third end 1103 to the fourth end 1104 of the E-pole driving surface 110, the second angle α2 formed by the second inclined surface 110b and the reference plane AA has an increasing trend. For example, it can increase within the range of 10°-60°.

[0093] Through the above solution, both the first bevel 110a and the second bevel 110b have a gradually changing slope along the insertion direction of the E-pole plug 001. This not only improves actuation smoothness and prevents potential deflection or jamming, but also facilitates low-resistance actuation and effortless insertion of the socket protection door 100, while also facilitating efficient actuation in the later stages of plug insertion. The second bevel 110b also facilitates precise control of the rotation trajectory and prevents jamming, while also facilitating efficient actuation in the later stages of plug insertion.

[0094] It should be noted that the first inclined surface 110a and the second inclined surface 110b together form the E-pole drive surface 110. Although the first inclined surface 110a has a tendency to tilt along the first direction, the first inclined surface 110a also extends and spreads along the second direction. Similarly, although the second inclined surface 110b has a tendency to tilt along the second direction, the second inclined surface 110b can still extend and spread along the first direction. In other words, the first end 1101 of the E-pole drive surface 110 intersects and smoothly transitions with its third end 1103 and fourth end 1104. The second end 1102 of the E-pole drive surface 110 also intersects and smoothly transitions with its third end 1103 and fourth end 1104.

[0095] It should be noted that, for the first inclined surface 110 a , the position corresponding to the change in the first angle α1 can be arranged at a slight angle or with a smooth transition.

[0096] Likewise, for the second inclined surface 110 b , the position corresponding to the change in the second angle α2 may be arranged at a slight angle or may be a smooth transition.

[0097] Regarding the above-mentioned increasing schemes of the first angle α1 and the second angle α2, their increasing trends may be linear changes (ie, gradual changes) or step-wise changes (ie, segmented changes).

[0098] In some examples, from the first end 1101 to the second end 1102 of the driving surface, the increasing trend of the first angle α1 formed by the first inclined surface 110a and the reference plane AA is a step-like change; and / or, the increasing trend of the second angle α2 formed by the second inclined surface 110b and the reference plane AA is a step-like change.

[0099] Among them, the number of steps of the step-by-step change of the first angle α1 and the second angle α2 is greater than or equal to 2, which includes but is not limited to 2, 3, 4, 5, 6, 7, 8, 9, 10, etc., and can be adaptively selected according to actual needs, and the shapes of the first inclined surface 110a and the second inclined surface 110b are also determined accordingly.

[0100] During the driving process of the socket protection door 100, the above-mentioned step-by-step change scheme is conducive to achieving segmented and precise control of the driving stroke, and is also conducive to improving the energy transfer efficiency, because the step-by-step change of the angle can form a mechanical gain peak at each angle change position, thereby improving the energy transfer efficiency.

[0101] For example, if Figure 3 -Attached Figure 5 As shown, the embodiment of the present invention illustrates a two-step variation scheme. Accordingly, from the first end 1101 to the second end 1102 of the E-pole driving surface 110, the first inclined surface 110a includes a first upper inclined surface segment 110a1 and a first lower inclined surface segment 110a2, and the first angle α1 between the first upper inclined surface segment 110a1 and the reference plane AA is smaller than the first angle α1 between the first lower inclined surface segment 110a2 and the reference plane AA. And / or, from the third end 1103 to the fourth end 1104 of the E-pole driving surface 110, the second inclined surface 110b includes a second upper inclined surface segment 110b1 and a second lower inclined surface segment 110b2, and the second angle α2 between the second upper inclined surface segment 110b1 and the reference plane AA is smaller than the second angle α2 between the second lower inclined surface segment 110b2 and the reference plane AA.

[0102] For further example, the first included angle α1 between the first inclined surface upper section 110a1 and the reference plane AA can be 10°-30°, and the first included angle α1 between the first inclined surface lower section 110a2 and the reference plane AA can be 20°-60°. The first included angle α1 between the second inclined surface upper section 110b1 and the reference plane AA can be 10°-30°, and the first included angle α1 between the second inclined surface lower section 110b2 and the reference plane AA can be 20°-60°.

[0103] In this solution, both the first upper bevel section 110a1 and the first lower bevel section 110a2 can be straight bevels, and the connection between the first upper bevel section 110a1 and the first lower bevel section 110a2 can be smoothly transitioned. Of course, the possibility that the first upper bevel section 110a1 and the first lower bevel section 110a2 are bevels with a certain curvature is not excluded.

[0104] Similarly, the second upper slope section 110b1 and the second lower slope section 110b2 can both be straight slopes, and the connection between the second upper slope section 110b1 and the second lower slope section 110b2 can be a smooth transition. Of course, the possibility that the second upper slope section 110b1 and the second lower slope section 110b2 are slopes with a certain curvature is not excluded.

[0105] The above describes the multi-directional composite tilt design of the E-pole driving surface 110 of the E-pole shielding portion 11. The E-pole driving surface 110 can be formed in a groove cavity provided on the surface of the E-pole shielding portion 11. The bottom wall of the groove cavity serves as the E-pole driving surface 110. The side walls on both sides of the groove cavity, that is, the side walls on both sides of the first end 1101 and the second end 1102 of the E-pole driving surface 110, respectively serve as stops for the E-pole pin 001 in the radial direction, ensuring that the E-pole pin 001 moves according to the set insertion stroke.

[0106] In combination with any of the above-mentioned socket protection doors 100, as shown in the attached Figure 1 As shown, the surface of the L-pole shielding portion 12 facing the socket has an L-pole drive surface 120, and the surface of the N-pole shielding portion 13 facing the socket has an N-pole drive surface 130. The socket protection door 100 is configured such that the L-pole drive surface 120 is driven by the L-pole pin 002, and the N-pole drive surface 130 is driven by the N-pole pin 003, both later than the E-pole drive surface 110 is driven by the E-pole pin 001. Furthermore, the driving of the L-pole drive surface 120 by the L-pole pin 002 and the driving of the N-pole drive surface 130 by the N-pole pin 003 occur simultaneously or sequentially. The aforementioned "simultaneous" approach corresponds to second-order actuation of the socket protection door, while the aforementioned "sequential" approach corresponds to third-order actuation of the socket protection door.

[0107] The above scheme can realize the staged driving (referred to as staged driving) of the socket protection door 100. Through the timing design of the E-pole shielding part 11 being prioritized and the L / N-pole shielding part 13 being delayed, it can not only ensure that the socket protection door 100 can be fully and completely driven, so that each shielding part is fully displaced to fully open the corresponding socket, but also can trigger the grounding priority protection, anti-arc and short-circuit protection, and enhanced protection against foreign object insertion, thereby helping to enhance the safety protection performance and electrical reliability of the socket.

[0108] When the socket protection door is driven in the second order or third order, there is a stage in which the E-pole driving surface 110 is driven by the E-pole pin, and the L-pole driving surface 120 is driven by the L-pole pin and / or the N-pole driving surface 130 is driven by the N-pole pin. For this stage, in some examples, the E-pole driving surface 110 can be made into sub-slant surfaces arranged along at least two different inclined directions, for example, one of the first slope 110a and the second slope 110b is configured to be driven by the E-pole pin, and the other is configured to cooperate with the drive of the L-pole driving surface 120 and / or the N-pole driving surface 130, thereby making the hierarchical driving scheme smoother.

[0109] As an example, socket protection door 100 is driven in a second-order manner. L-pole drive surface 120 is driven by L-pole pin 002, and N-pole drive surface 130 is driven by N-pole pin 003. Both are driven simultaneously and later than E-pole drive surface 110 is driven by E-pole pin 001. E-pole drive surface 110 is a first-order drive surface, while L-pole drive surface 120 and N-pole drive surface 130 are both second-order drive surfaces.

[0110] In combination with the above-mentioned second-order driving scheme, the embodiment of the present invention exemplarily illustrates the working principle of the socket protection door 100 in the socket.

[0111] When the socket is in its normal state (i.e., its natural state), with no plug inserted, the socket protection door 100 shields the E-pole socket 201, L-pole socket 202, and N-pole socket 203 through its E-pole shielding portion 11, L-pole shielding portion 12, and N-pole shielding portion 13, respectively, to prevent objects from accidentally entering the socket through the socket and causing electric shock. When the plug is initially inserted, the E-pole pin 001 first contacts the E-pole driving surface 110 of the E-pole shielding portion 11. At this point, a gap H exists between the L-pole pin 002 and the L-pole driving surface 120 of the L-pole shielding portion 12, and between the N-pole pin 003 and the N-pole driving surface 130 of the N-pole shielding portion 13. The socket protection door 100 still shields the sockets.

[0112] As the plug continues to be inserted, the E-pole plug 001 applies a driving force to the E-pole drive surface 110. As a first-order drive surface, the E-pole drive surface 110 has at least two inclined directions, so that the force applied by the E-pole plug 001 to the socket protection door 100 is converted into a force consistent with the rotation direction of the socket protection door 100, causing the socket protection door 100 to rotate. When the E-pole plug 001 reaches the edge of the E-pole drive surface 110, the E-pole plug 001 can no longer apply a driving force to the socket protection door 100. At this point, the first-order drive is complete. At the same time, the distance between the L-pole plug 002 and the L-pole drive surface 120 of the L-pole shielding portion 12, and the N-pole plug 003 and the N-pole drive surface 130 of the N-pole shielding portion 13, is zero, i.e., they are in contact.

[0113] As the latch continues to be inserted, second-order actuation begins. L-pole actuation surface 120 and N-pole actuation surface 130, acting as second-order actuation surfaces, have at least two inclined directions. This allows the force applied by L-pole and N-pole latches 002 and 003 to be converted into a force aligned with the rotational direction of door 100, causing door 100 to rotate. Second-order actuation is complete when L-pole and N-pole latches 002 and 003, respectively, reach the edges of L-pole and N-pole actuation surfaces 120 and 003, respectively, at which point they no longer exert actuating force on door 100. Simultaneously, door 100 fully opens, allowing the socket to connect and disconnect circuits.

[0114] As another example, the socket protection door 100 is driven in three orders, the L-pole driving surface 120 is driven by the L-pole pin 002 later than the N-pole driving surface 130 is driven by the N-pole pin 003, and the N-pole driving surface 130 is driven by the N-pole pin 003 later than the E-pole driving surface 110 is driven by the E-pole pin 001, that is, in order of driving sequence, they are E-pole shielding part 11-N-pole shielding part 13-L-pole shielding part 12, the E-pole driving surface 110 is a first-order driving surface, the N-pole driving surface 130 is a second-order driving surface, and the L-pole driving surface 120 is a third-order driving surface.

[0115] As another example, the socket protection door 100 is driven in three orders, the N-pole driving surface 130 is driven by the N-pole pin 003 later than the L-pole driving surface 120 is driven by the L-pole pin 002, and the L-pole driving surface 120 is driven by the L-pole pin 002 later than the E-pole driving surface 110 is driven by the E-pole pin 001, that is, in order of driving sequence, they are E-pole shielding portion 11-L-pole shielding portion 12-N-pole shielding portion 13, the E-pole driving surface 110 is a first-order driving surface, the L-pole driving surface 120 is a second-order driving surface, and the N-pole driving surface 130 is a third-order driving surface.

[0116] It should be noted that in the three-order driving scheme, the working principle of the socket protection door 100 can refer to the above-mentioned two-order driving scheme, the only difference is that the driving of the L-pole driving surface 120 and the driving of the N-pole driving surface 130 are not synchronized, and the two are driven one in front and the other behind.

[0117] Typically, the E-pole pin 001 of the plug is longer than its L-pole pin 002 and N-pole pin 003, which is more favorable for the driving priority of the E-pole shielding portion 11. In order to further adapt to the above-mentioned step-by-step driving scheme, as shown in the attached Figure 1 As shown, the surfaces of the L-pole shielding portion 12 and the N-pole shielding portion 13 facing the socket can be located below the surface of the E-pole pin 001 facing the socket, so that along the insertion direction of the pin, the L-pole driving surface 120 and the N-pole driving surface 130 are lower than the E-pole driving surface 110, so that the stepped driving can be carried out smoothly.

[0118] Based on the actual step-by-step driving scheme, the positions and orientations of the L-pole driving surface 120 and the N-pole driving surface 130 can be further adaptively designed. For example, when the socket protection door 100 adopts a two-step driving scheme, the L-pole driving surface 120 and the N-pole driving surface 130 can be aligned in the direction of insertion of the plug.

[0119] In an embodiment of the present invention, the main body 10 of the socket protection door 100 can be, for example, a disc-shaped, and the three shielding parts are respectively located on the circumferential sides of the main body 10, so that the structure of the socket protection door 100 is a trident-shaped. For the above-mentioned second-order drive scheme, the structures of the L-pole shielding part 12 and the L-pole driving surface 120, and the N-pole shielding part 13 and the N-pole driving surface 130 can be set to be the same.

[0120] The shape of each shielding portion can be adaptively designed according to the shape of the jack, so as to effectively shield the jack without increasing the size of the shielding portion.

[0121] In order to achieve sufficient shielding of the socket, the size of the orthographic projection of the surface facing the socket (i.e., the shielding surface) of the E-pole shielding portion 11 on the plane where the socket is located can be made larger than the size of the E-pole socket 201, and the size of the orthographic projection of the surface facing the socket of the L-pole shielding portion 12 on the plane where the socket is located can be made larger than the size of the L-pole socket 202, and the size of the orthographic projection of the surface facing the socket of the N-pole shielding portion 13 on the plane where the socket is located can be made larger than the size of the N-pole socket 203.

[0122] Taking the socket as a rectangular socket as an example, each shielding portion can be made into a rectangular block shape. Accordingly, the length of each shielding portion is greater than the length of the corresponding socket, and the width of each shielding portion is greater than the width of the corresponding socket.

[0123] Suitable for step-by-step driving of the socket protection door 100, as shown in the attached Figure 1 and attached Figure 6 As shown, the L-pole driving surface 120 can be located on the side of the L-pole shielding portion 12 that is located upstream of the rotation path, and the N-pole driving surface 130 can be located on the side of the N-pole shielding portion 13 that is located upstream of the rotation path. This ensures the L-pole driving and N-pole driving effects while also helping to reduce the sizes of the L-pole driving surface 120 and the N-pole driving surface 130, and correspondingly increase the shielding surface areas of the L-pole shielding portion 12 and the N-pole shielding portion 13, thereby improving the shielding effect.

[0124] In combination with any of the socket protection doors 100 mentioned above, in some examples, at least one of the L-pole drive surface 120 and the N-pole drive surface 130 can be tilted along two different tilt directions to promote the socket protection door 100 to rotate along a set rotation path. For example, both the L-pole drive surface 120 and the N-pole drive surface 130 are tilted along two different tilt directions.

[0125] The working principle of the multi-inclined direction composite slope design of the L-pole driving surface 120 and the N-pole driving surface 130 can be found in the above-mentioned explanation of the multi-inclined direction composite slope design of the E-pole driving surface 110, which will not be repeated here. Based on the above-mentioned working principle, the shapes of the L-pole driving surface 120 and the N-pole driving surface 130 can be adaptively designed.

[0126] The above solution can further optimize the driving effect of the socket protection door 100, improve the driving smoothness, and reduce the driving force by making the three-pole driving surfaces tilt in multiple directions.

[0127] In some examples, the E-pole driving surface 110, the L-pole driving surface 120 and the N-pole driving surface 130 can all be designed to be turbine-shaped curved surfaces. Of course, it is not ruled out that at least one of the L-pole driving surface 120 and the N-pole driving surface 130 can also be designed to be tilted in one direction, which will not affect the effective driving of the socket protection door 100.

[0128] Regarding the socket protection door 100 involved above, as shown in the attached Figure 2 As shown, at least one of the E-pole shielding portion 11, the L-pole shielding portion 12 and the N-pole shielding portion 13 has a chamfered structure 14 on the side of the surface facing away from the socket and located downstream of the rotation path. The chamfered structure 14 can be, for example, an oblique angle shape, an arc shape, etc. The chamfered structure 14 is used to guide the socket protection door 100 to rotate along the set rotation path and / or for avoidance.

[0129] The socket protection door 100 is usually arranged between the socket cover 300 and the pressure plate 400. By setting the chamfer structure 14, the various shielding parts of the socket protection door 100 can be prevented from interfering with the pressure plate 400 during the rotation process, thereby achieving the avoidance function. In addition, the chamfer structure 14 can also guide the rotation of the socket protection door 100. All of the above are conducive to further improving the driving smoothness of the socket protection door 100.

[0130] In summary, the socket protection door 100 involved in the embodiment of the present invention, based on its structural design, has at least the following advantages: the driving process is smoother, the driving force is smaller, the driving stroke is short, the height of the protection door can be made lower, and the area occupied at the height of the socket can be smaller, which is more conducive to spatial arrangement and more conducive to improving the safety protection performance of the socket.

[0131] The socket protection door 100 involved in the embodiment of the present invention is applied to a three-pole socket. The socket of the three-pole socket can be a rectangular socket or a circular socket. The shape of each shielding part on the socket protection door 100 can be designed according to the actual socket type. Regardless of the similar socket, it has the effect brought by the above-mentioned socket protection door 100.

[0132] On the other hand, an embodiment of the present invention further provides a socket, as shown in the attached Figure 7 and attached Figure 8 As shown, the socket includes: a socket protection door 100, a panel 200, a cover 300, a pressure plate 400, a fixing frame 500, an elastic reset member 600 and a socket assembly 700. The socket protection door 100 is such as the socket protection door 100 described in any of the above embodiments of the present invention.

[0133] The face cover 300, the socket protection door 100, the pressure plate 400 and the socket assembly 700 are sequentially arranged in the cavity formed by the panel 200 and the fixing frame 500; the socket protection door 100 is rotatably connected to the pressure plate 400 to switch between a position of blocking the socket and a position of exposing the socket; the elastic reset member 600 is located between the socket protection door 100 and the pressure plate 400, and is used to automatically reset the socket protection door 100 from a position of exposing the socket to a position of blocking the socket.

[0134] The socket provided by the embodiment of the present invention has all the advantages of the socket protection door 100 involved in the embodiment of the present invention.

[0135] Among them, an elastic reset member 600 is arranged between the socket protection door 100 and the pressure plate 400. When the socket protection door 100 rotates from a position blocking the socket to a position exposing the socket, the elastic reset member 600 is deformed, and then based on its stored elastic potential energy, it promotes the socket protection door 100 to perform a reset movement from the position exposing the socket to the position blocking the socket.

[0136] Specifically, when the pin is pulled out of the socket, the socket protection door 100 rotates in the opposite direction under the rebound force of the elastic reset member 600, so that the socket protection door 100 is reset from the position of opening the socket to the position of blocking the socket.

[0137] In the embodiment of the present invention, the elastic return member 600 can be in the form of a torsion spring, a compression spring, a tension spring, an elastic rubber member, etc., as long as it can automatically return the socket protection door 100 to its original position. To better accommodate the rotation of the socket protection door 100, the elastic return member 600 can be in the form of a torsion spring. This example is described below.

[0138] As attached Figure 2 , Attachment Figure 9 -Attached Figure 11 As shown, the main body 10 of the socket protection door 100 has a first receiving groove 101 on one side away from the socket, and the pressure plate 400 has a rotating shaft 401 that passes through the first receiving groove 101 and is rotatably connected to the main body 10 .

[0139] For example, the first receiving groove 101 is a circular groove cavity. Furthermore, the central axis of the first receiving groove 101 and the central axis of the main body 10 can coincide with each other.

[0140] As attached Figure 12 As shown, the elastic return member 600 is a torsion spring structure, including a spring body 601 and a first torsion arm 602 and a second torsion arm 603 connected to both sides of the spring body 601. The spring body 601 is sleeved on the rotating shaft 401 and is located inside the first accommodating groove 101. One of the first torsion arm 602 and the second torsion arm 603 is connected to or abuts the pressure plate 400, and the other is connected to or abuts the socket protection door 100.

[0141] By accommodating the elastic return member 600 within the first receiving groove 101 defined in the main body 10, the internal space of the socket is more fully utilized, the volume occupied by the elastic return member 600 is reduced, and a compact design of the socket is achieved. Furthermore, this solution simplifies the assembly process of the elastic return member 600 in the socket, shortening assembly time and reducing assembly difficulty.

[0142] It should be noted that the diameter of the first accommodating groove 101 is greater than the diameter of the spring body 601, and the depth of the first accommodating groove 101 is greater than the height of the elastic return member 600, so as to facilitate the assembly of the elastic return member 600 and enable the elastic return member 600 to have a sufficiently large activity space to achieve torsion avoidance of the elastic return member 600.

[0143] Of course, the arrangement of the elastic return member 600 is not limited to the above, and other arrangements may also be adopted. For example, it is also feasible to arrange it on one side of the main body 10 .

[0144] As mentioned above, the pressing plate 400 has a rotating shaft 401 . Adaptively, a shaft hole 103 is provided in the middle of the main body 10 of the socket protection door 100 . The shaft hole 103 is used for rotatably connecting with the rotating shaft 401 .

[0145] For example, the center axis of the rotating shaft 401 can coincide with the center line intersection point of the three sockets of the socket, and the center of the shaft hole 103 coincides with the center line intersection point of the three sockets of the socket, so that the socket protection door 100 is arranged in the center relative to the socket area.

[0146] The diameter of the rotating shaft 401 is slightly smaller than the aperture of the shaft hole 103 , for example, the difference between the two may be 0.05 mm-1 mm, so as to allow the socket protection door 100 to rotate smoothly around the rotating shaft 401 .

[0147] In some examples, the axial height of the rotating shaft 401 may be greater than the axial depth of the shaft hole 103 , so that the end of the rotating shaft 401 away from the pressing plate 400 extends to the side of the shaft hole 103 close to the surface cover 300 .

[0148] It should be noted that the end of the rotating shaft 401 away from the pressure plate 400 should not interfere with the cover 300. In order to facilitate the assembly between the rotating shaft 401 and the shaft hole 103, the end of the rotating shaft 401 away from the pressure plate 400 is provided with a buckle 4010 and is retractable along the radial direction of the shaft hole 103. For example, this can be achieved by designing the end of the rotating shaft 401 to be hollow. Thus, based on its elastic compression performance, the end of the rotating shaft 401 can smoothly pass through the shaft hole 103, so as to facilitate the assembly and disassembly between the rotating shaft 401 and the main body 10. After elastic reset, the end of the rotating shaft 401 returns to a naturally stretched state, so that its buckle 4010 can be snapped onto the main body 10, thereby achieving a reliable connection between the rotating shaft 401 and the main body 10.

[0149] Furthermore, the end of the shaft hole 103 facing the pressure plate 400 can be set to a chamfered structure, thereby guiding the insertion of the buckle 4010 of the shaft 401, simplifying the assembly of the socket protection door 100 and the pressure plate 400.

[0150] In order to further enhance the assembly stability of the elastic reset member 600 in the socket, as shown in the attached Figure 13 As shown, the pressure plate 400 has a torsion spring fixing column 402, which is located on one side of the rotating shaft 401. The side wall of the receiving groove of the main body 10 has a through hole 104 (see Figure 2 ); the end of one of the first torsion arm 602 and the second torsion arm 603 away from the spring body 601 is fixedly connected to the torsion spring fixing column 402, and the end of the other away from the spring body 601 passes through the through hole 104 and abuts against the outer wall of the main body 10.

[0151] The first torsion arm 602 and the second torsion arm 603 can be arranged on two different sides of the spring body 601. The angle between the first torsion arm 602 and the second torsion arm 603 and the spring body 601 can be less than or equal to 90°. For example, the first torsion arm 602 and the second torsion arm 603 can both be arranged tangentially to the spring body 601.

[0152] For example, if Figure 12 As shown, the first torsion arm 602 is fixedly connected to the torsion spring fixing column 402, and the end of the first torsion arm 602 away from the spring body 601 is an annular end 6020. The annular end 6020 of the first torsion arm 602 is sleeved on the torsion spring fixing column 402 to achieve a fixed connection between the two, wherein the annular end 6020 of the first torsion arm 602 can be completely closed or partially closed in the circumferential direction, as long as it is ensured that the torsion spring fixing column 402 is not easy to fall out. For example, it can be a circular ring, a rectangular ring, etc., and the degree of closure in the circumferential direction is at least 3 / 4.

[0153] It should be noted that the distance between the center of the torsion spring fixing post 402 and the center of the rotating shaft 401 is equal to the distance between the center of the collar-shaped end 6020 of the first torsion arm 602 and the center of the spring body 601, to facilitate the precise assembly of the elastic return member 600 therein. Furthermore, the height of the torsion spring fixing post 402 is less than the depth of the first receiving groove 101 of the main body 10 to avoid interference. Furthermore, in embodiments of the present invention, the shape of the torsion spring fixing post 402 includes, but is not limited to, a cylindrical shape.

[0154] The end of the second torsion arm 603 away from the spring body 601 passes through the through hole 104 of the main body 10 and abuts against the outer wall of the main body 10. For example, the end of the second torsion arm 603 away from the spring body 601 is bent to form a bent end 6030, and the bending angle of the bent end 6030 is greater than or equal to 90°. For example, the bent end 6030 of the first torsion arm 602 can be L-shaped, and its bending part is used to achieve abutment with the outer wall of the main body 10.

[0155] It should be noted that the planes of the first torsion arm 602 and the second torsion arm 603 of the elastic return member 600 are parallel to each other. The above design of the first torsion arm 602 and the second torsion arm 603 is particularly beneficial for simplifying the assembly process of the elastic return member 600 in the socket, improving assembly efficiency, and reducing assembly difficulty.

[0156] In some examples, the through hole 104 and the torsion spring fixing column 402 on the main body 10 can be respectively positioned in appropriate positions so that when the socket protection door 100 is in the normal state of blocking the socket (i.e., the state without the plug inserted), the elastic return member 600 has a certain degree of initial torsion (i.e., the elastic return member 600 has a certain pre-tightening force). The initial torsion angle is, for example, greater than 1°, and further can be less than 10°. The elastic return member 600 applies the pre-tightening force to the socket protection door 100, so that the socket protection door 100 is stably in the state of blocking the socket. The larger the initial torsion angle of the elastic return member 600, the greater the pre-tightening force it applies to the socket protection door 100. At this time, the greater the driving force required for the plug to drive the socket protection door 100 to rotate. The initial torsion angle of the elastic return member 600 can be designed according to actual needs.

[0157] In some embodiments, as shown in the accompanying Figure 9 -Attached Figure 11 As shown, the surface of the pressure plate 400 facing the socket protection door 100 has a raised first guide rail structure 403, which is used to contact the side of the E-pole shielding part 11, the L-pole shielding part 12 and the N-pole shielding part 13 facing the pressure plate 400.

[0158] For example, the first guide rail structure 403 is a thin strip-shaped protrusion. That is, the width of the first guide rail structure 403 is sufficiently small along a direction parallel to the pressure plate 400. Moreover, the first guide rail structure 403 can be substantially distributed along the rotation trajectory of the protective door. Furthermore, the surface of the first guide rail structure 403 facing away from the pressure plate 400 can be, for example, an arcuate surface.

[0159] In some examples, the first guide rail structure 403 includes: a first raised portion formed on the periphery of the socket of the pressure plate 400, and a second raised portion formed between any two adjacent sockets on the pressure plate 400, wherein the shape of the first raised portion is adapted to the shape of the socket, for example, the socket is a rectangular hole, the first raised portion is also a rectangular ring, and the second raised portion is an arc shape, so as to adapt to the rotation trajectory of each shielding part of the socket protection door 100.

[0160] By setting the first guide rail structure 403, the friction between the socket protection door 100 and the pressure plate 400 is reduced when the socket protection door 100 rotates. At the same time, it can also prevent the socket protection door 100 from tilting when it rotates, making the opening and returning process of the socket protection door 100 smoother and improving the user's driving feel.

[0161] In some embodiments, as shown in the accompanying Figure 10As shown, the surface of the pressure plate 400 facing the socket protection door 100 has at least one stop block 404, and the at least one stop block 404 abuts against at least one of the E-pole shielding part 11, the L-pole shielding part 12 and the N-pole shielding part 13, and is used to prevent the socket protection door 100 from rotating in a direction opposite to the set rotation path.

[0162] For example, Figure 10 The example shows that the surface of the pressing plate 400 facing the socket protection door 100 has a stop block 404 , and the stop block 404 abuts against the E-pole shielding portion 11 .

[0163] It should be noted that the height of the stop block 404 must be designed so as not to cause any interference with the cover 300 .

[0164] When the latch is removed from the socket, the socket protection door 100 rotates in the opposite direction due to the rebound force of the elastic return member 600, causing the socket protection door 100 to return from the position of opening the socket to the position of blocking the socket. During this process, the socket protection door 100 is stopped by the stop block 404 during the reset movement, thus smoothly returning to the initial position. As can be seen, the design of the stop block 404 can effectively prevent the socket protection door 100 from moving in the direction opposite to the set rotation path, while also ensuring that the socket protection door 100 remains stable in its initial position of blocking the socket under normal conditions.

[0165] In combination with the socket solution mentioned above, in some examples, such as the attached Figure 14 -Attached Figure 15 As shown, the surface of the cover 300 facing the socket protection door 100 has a convexly arranged second guide rail structure 301 , and the second guide rail structure 301 is used to contact the side of the main body 10 facing the cover 300 .

[0166] For example, the second guide rail structure 301 is a thin strip-shaped protrusion, that is, the width of the second guide rail structure 301 is small enough along the direction parallel to the cover 300. Furthermore, the surface of the second guide rail structure 301 facing away from the cover 300 can be, for example, an arcuate surface.

[0167] By setting the second guide rail structure 301, the friction between the socket protection door 100 and the surface cover 300 is reduced when the socket protection door 100 rotates. At the same time, it can also prevent the socket protection door 100 from tilting when rotating, making the opening and returning process of the socket protection door 100 smoother and improving the user's driving feel.

[0168] Furthermore, as attached Figure 15As shown, the surface of the main body 10 facing the cover 300 has a second accommodating groove 102. The second accommodating groove 102 and the second guide rail structure 301 are both annular. The second guide rail structure 301 is accommodated in the second accommodating groove 102 and the central axes of the two coincide with each other.

[0169] Through this solution, the main body 10 is adapted to be mounted on the outer side of the second guide rail structure 301 through its second accommodating groove 102. The second guide rail structure 301 can also guide the rotation of the socket protection door 100, thereby improving the rotation stability and reliability of the socket protection door 100.

[0170] It should be noted that the inner diameter of the annular second guide rail structure 301 should be larger than the outer diameter of the latch 4010 at the end of the rotating shaft 401 to avoid interference with the rotating shaft 401. The central axis of the annular second guide rail structure 301 and the central axis of the second receiving groove 102 can both coincide with the centerline intersection of the three sockets of the socket to ensure that the socket protection door 100 is centered relative to the socket area.

[0171] In some examples, such as the attached Figure 14 As shown, an annular stop wall 302 is provided on the side of the cover 300 facing the socket protection door 100. The socket protection door 100 is accommodated within the annular stop wall 302 to protect the socket protection door 100. At the same time, the end of the annular stop wall 302 facing away from the cover 300 can abut against the pressure plate 400, facilitating the stable assembly of the cover 300 and the pressure plate 400 in the socket, thereby achieving the purpose of improving the socket's structural stability and operational reliability.

[0172] For the socket involved in the embodiment of the present invention, the jack thereon can be a rectangular jack or a round jack. Taking the rectangular jack as an example, in some examples, such as the attached Figure 7 As shown, the socket has an E-pole socket 201 provided on a panel 200 and a cover 300 , and the E-pole socket 201 is a horizontally arranged rectangular socket.

[0173] For further example, when the socket includes a transversely arranged rectangular E-pole socket 201 , the socket may be a single-phase 32A socket.

[0174] The present invention provides a socket protection door 100 for horizontally arranged E-pole sockets, particularly single-phase 32A sockets. Located between the socket and the socket, the door prevents objects from accidentally entering the socket through the socket, potentially causing electric shock. Currently, there are no mature socket protection doors 100 for single-phase 32A sockets with horizontally arranged E-pole sockets, let alone a staged actuation system. This solution fills a significant gap in the industry.

[0175] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0176] The above description is only for the purpose of facilitating those skilled in the art to understand the technical solution of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
