DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] In the description of this application, it should be understood that the words "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description". Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in this application.

[0036] See also Figures 1 to 7 , an embodiment of the present application proposes a protective door assembly 100, comprising:

[0037] The protective cover 110 is provided with a placement groove 111, and the placement groove 111 has a length direction X and a width direction Y;

[0038] The protection door 120 is slidably disposed in the placement groove 111, and the sliding direction of the protection door 120 is the length direction X;

[0039] The bottom wall of the placement groove 111 is provided with supporting ribs 112, and the supporting ribs 112 extend along the length direction X. The protection door 120 is arranged on the supporting ribs 112 so that the protection door 120 is spaced apart from the bottom wall of the groove during sliding.

[0040] The technical solution provided by the present application is mainly to set a support rib 112 on the bottom wall of the placement groove 111 to support the protection door 120, so that the protection door 120 is spaced from the bottom wall of the placement groove 111, reduce the contact area between the protection door 120 and the placement groove 111, effectively reduce the friction between the protection door 120 and the placement groove 111, improve the smoothness of the movement of the protection door 120, and improve the problem of the protection door 120 being stuck when moving. Among them, the protection cover 110 is mainly used to provide an installation position for the protection door 120, so that the protection door 120 can be installed in the socket, and the protection cover 110 can also play a certain protective role for the protection door 120. For the placement groove 111, it is in a T shape, and correspondingly, the protection door 120 is also in a T shape. The size of the placement groove 111, especially the size in the length direction X, is larger than the size of the protection door 120, so that the protection door 120 can move in the placement groove 111 along the length direction X, thereby changing the position of the protection door 120.

[0041] In some embodiments, see Figures 1 to 3 as well as Figure 7, the protective door assembly 100 also includes an elastic member 130. The elastic member 130 is preferably a spring in this embodiment, because the spring is simple to make, low in cost, and can be selected according to the distance that the protective door 120 needs to move or the size of the placement slot 111. A retaining wall 113 is provided on the bottom wall of the slot, and the elastic member 130 is arranged in the placement slot 111 and contacts the retaining wall 113. The contact here can be to fix the elastic member 130 to the retaining wall 113, or to simply contact the retaining wall 113. In this embodiment, the elastic member 130 is fixedly connected to the retaining wall 113, which is conducive to stabilizing the spring and avoiding the spring from tilting or even bouncing off. The end of the elastic member 130 that is away from the retaining wall 113 contacts the main section 121 and is located between the two protrusions 125. The contact here can also be that the elastic member 130 is fixedly connected or in contact with the main section 121. In this embodiment, the main section 121 is provided with a sleeve column 1222, which is located between the two protrusions 125, and the end of the elastic member 130 away from the retaining wall 113 is sleeved in the sleeve column 1222, thereby effectively preventing the elastic member 130 from being offset, and because the elastic member 130 is only sleeved on the sleeve column 1222 and is not fixedly connected, it will not hinder the disassembly between the protection door 120 and the protection cover 110. By providing the elastic member 130, the automatic reset of the protection door 120 can be achieved, and the recycling of the protection door 120 can be achieved.

[0042] It should be noted that, for the protection cover 110 and the protection door 120, the protection cover 110 is made of high-strength PC material, and the protection door 120 is made of PA66+30% glass fiber, and the molding method is injection molding. Since the material PA66 itself has a certain degree of self-lubricating properties, it is helpful to improve the smoothness of movement of the protection door 120. By improving the smoothness of movement between the protection door 120 and the protection cover 110, the friction loss caused by each movement of the protection door 120 is minimized, which is helpful to extend the service life of the protection door assembly 100, so that the number of normal back and forth movements between the protection door 120 and the protection cover 110 can reach more than 30,000 times.

[0043] See also Figure 1 and Figure 2, the protection door assembly 100 has two states, namely, a closed state and an open state. The switching between the closed state and the open state is mainly achieved by controlling the movement of the protection door 120 in the placement slot 111. In detail, in some embodiments, the protection door 120 includes a main body section 121, a first protection section 122, a second protection section 123 and a third protection section 124; along the length direction X, the first protection section 122 is connected to a side of the main body section 121 away from the retaining wall 113, where the retaining wall 113 is a retaining wall 113 provided on the bottom wall of the slot; along the width direction Y, the second protection section 123 and the third protection section 124 are respectively connected to both sides of the main body section 121, and along the length direction X, the second protection section 123 and the third protection section 124 are both located on a side away from the first protection section 122;

[0044] The bottom wall of the placement groove 111 is provided with a first plug hole 114, a second plug hole 115 and a third plug hole 116. The first plug hole 114 is arranged opposite to the sliding path of the first protection section 122, the second plug hole 115 is arranged opposite to the sliding path of the second protection section 123, and the third plug hole 116 is arranged opposite to the sliding path of the third protection section 124.

[0045] When the protection door assembly 100 is in the closed state, the first protection section 122 is aligned with the first plug hole 114 to close the first plug hole 114; the second protection section 123 is aligned with the second plug hole 115 to close the second plug hole 115; the third protection section 124 is aligned with the third plug hole 116 to close the third plug hole 116. At this time, the protection door assembly 100 plays a protective role to prevent the plug from being inserted into the wrong position or the person accidentally touching the socket and causing electric shock. When the plug is correctly inserted into the protection door assembly 100, the protection door assembly 100 is in the open state, and the plug can be electrically connected to the socket. Here, the plug is correctly inserted into the protection door assembly 100 means that the corresponding electrode of the plug is correctly inserted into the corresponding plug hole of the protection door assembly 100. In this embodiment, the first plug hole 114 is used to plug in the ground wire, and the second plug hole 115 and the third plug hole 116 are used to plug in the neutral wire and the live wire or to plug in the live wire and the neutral wire respectively. Only when the three electrodes of the plug are correctly inserted into the socket, the protective door assembly 100 will switch to the open state, so that the plug and the socket are electrically connected. The specific process of switching the protective door assembly 100 from the closed state to the open state is as follows:

[0046] When the ground wire pin of the plug is inserted into the first plug hole 114, the ground wire pin will squeeze the first protection section 122, so that the first protection section 122 moves along the length direction X and opens the first plug hole 114. Accordingly, since the first protection section 122 is connected to the main section 121, the second protection section 123 and the third protection section 124 as a whole, the movement of the first protection section 122 will also drive the main section 121, the second protection section 123 and the third protection section 124 to move, so that the second protection section 123 and the third protection section 124 open the second plug hole 115 and the third plug hole 116 respectively, and at this time, the live wire pin and the neutral wire pin of the plug will also be inserted into the corresponding plug holes to realize the electrical connection between the plug and the socket. When, due to some unexpected circumstances, other conductive or insulating objects other than plugs, such as needle-shaped objects, are inserted toward the second protection segment 123 or the third protection segment 124, since the first protection segment 122 is not subjected to pressure at this time, the protection door 120 is in a closed state, that is, the second protection segment 123 and the third protection segment 124 block the corresponding second plug hole 115 and the third plug hole 116, and other objects other than plugs cannot be inserted into the second plug hole 115 or the third plug hole 116 at this time, and will not come into contact with the charged body in the socket, thereby playing a role of safety protection.

[0047] Please note that Figures 3 to 6 For the first protection section 122, the side away from the bottom wall of the groove, that is, the side for contacting the plug, is inclined to form a guide surface 1221. Along the direction of the plug insertion, the height of the guide surface 1221 gradually decreases along the length direction X. Through the setting of the guide surface 1221, when the electrode of the plug is inserted toward the first plug hole 114, the first protection section 122 is squeezed and continues to be fed toward the first plug hole 114 along the guide surface 1221, so that the first protection section 122 can move in the length direction X.

[0048] In some embodiments, the first protection segment 122, the second protection segment 123, and the third protection segment 124 are all spaced apart from the slot wall of the placement slot 111, so that the protection segment and the slot wall of the placement slot 111 are non-contacted, thereby reducing the contact area that can generate friction between the protection segment and the placement slot 111, and improving the smoothness of movement of the protection door 120. The side surface of the main body segment 121 along the length direction X and the side surface along the width direction Y are spaced apart from the slot side wall of the placement slot 111, so that the main body segment 121 and the slot side wall of the placement slot 111 are non-contacted, and the smoothness of movement of the protection door 120 is improved.

[0049] In some embodiments, see Figure 5 and Figure 6The protection door 120 includes a main body section 121, and two protrusions 125 are provided on one side of the main body section 121 facing the bottom wall of the groove. The two protrusions 125 extend along the length direction X and are arranged in parallel along the width direction Y. By providing two oppositely arranged protrusions 125 in contact with the bottom wall of the groove, compared with the entire surface of the main body section 121 in contact with the bottom wall of the groove, the contact area can be effectively reduced, which is conducive to the movement of the protection door 120 in the placement groove 111, and the two protrusions 125 are arranged oppositely to each other, which can also ensure the balance and stability of the main body section 121.

[0050] In some embodiments, see Figure 5 and Figure 6 The protrusion 125 includes a contact surface 1251, an extension surface 1253 and a connection surface 1252. The contact surface 1251 extends along the length direction X and contacts the support rib 112. The extension surface 1253 is arranged opposite to the bottom wall of the groove and extends toward the bottom wall of the groove. The contact surface 1251 and the extension surface 1253 are connected by the connection surface 1252, and the connection surface 1252 is in an arc shape. The protrusion 125 is in a plate shape. The contact surface 1251 is the bottom surface of the protrusion 125. The extension surface 1253 is the side surface of the protrusion 125. The connection surface 1252 is the corner where the contact surface 1251 and the extension surface 1253 are connected. By setting the corner as the arc-shaped connection surface 1252, it is helpful to further improve the problem of movement jamming due to burrs on the surface workmanship of the protection door 120 and / or the protection cover 110. In detail, in the comparative example: if the connecting surface 1252 is not provided at the corner of the protrusion 125, and the contact surface 1251 is directly connected to the extension surface 1253 at an angle, then both the extension surface 1253 and the contact surface 1251 need to be extended longer, and the burrs on the extension surface 1253 and the contact surface 1251 may get stuck with the support rib 112 due to the burrs when the protective door 120 moves. If the corner moves to one side of the support rib 112, the burrs are more likely to abut against the side of the support rib 112, causing the movement of the protective door 120 to be obstructed. In the present embodiment, an arc-shaped connecting surface 1252 is provided at the corner, thereby shortening the extension length of the extension surface 1253 and the contact surface 1251, and effectively shortening the contact length between the protrusion 125 and the support rib 112. Even if there are more burrs on the connecting surface 1252, when the movable door moves the same distance as the aforementioned comparative example, especially when the burrs in the moving comparative example are more likely to form abutment with the side of the support rib 112, the connecting surface 1252 of the present embodiment is in an arc shape, and will not abut with the side of the support rib 112 due to the burrs. That is to say, the movement jamming problem of the protective door 120 can be improved to a certain extent.

[0051] For further information, see Figure 3, the number of the supporting ribs 112 is two, and the two supporting ribs 112 are arranged relatively along the width direction Y. Among them, the supporting ribs 112 are in one-to-one correspondence with the protrusions 125. Similarly, this embodiment improves the front contact between the protrusion 125 and the bottom wall of the groove into the contact between the contact surface 1251 of the protrusion 125 and the supporting rib 112, further making the contact area between the protective door 120 and the protective cover 110 as small as possible, thereby achieving the effect of reducing friction and improving the smoothness of the movement of the protective door 120. Even if the workmanship accuracy of the protective cover 110 and the protective door 120 on the contact surface with each other is low, there are many burrs, and the friction resistance is large, the effect of reducing friction can be achieved through the cooperation between the above-mentioned supporting ribs 112 and the protrusions 125. It should be noted that the supporting ribs 112 and the contact surface 1251 are treated with a high-gloss surface in the mold design, that is, the friction contact surface position is smoother and the component movement is smoother.

[0052] Furthermore, a rib groove is provided on the side of the protrusion 125 facing the support rib 112, that is, a rib groove is provided on the contact surface 1251. The support rib 112 is arranged in the rib groove and slidably cooperates with the rib groove. By limiting the support rib 112 in the rib groove, it is beneficial to improve the stability of the movement of the protection door 120 in the length direction X and reduce the displacement of the protection door 120 in the width direction Y. By reducing the displacement of the protection door 120 in the width direction Y, it is possible to avoid the side of the protection door 120 from forming friction with the inner wall of the placement groove 111, thereby further improving the smoothness of the movement of the protection door 120. In addition, the inner wall of the rib groove is also treated with a high-gloss surface like the contact surface 1251, so that the surface where the support rib 112 and the rib groove are in friction contact with each other is smoother.

[0053] It should be noted that, for the cooperation between the rib groove and the support rib 112, a clearance cooperation is adopted in this embodiment, which can reduce the contact area between the rib groove and the support rib 112 as much as possible while limiting the support rib 112 to move stably in the rib groove.

[0054] In some embodiments, please participate Figure 3 , along the projection of the sliding direction of the protection door 120, that is, along the projection of the length direction X, the support rib 112 is in an arc shape, and the arc top of the support rib 112 contacts the protrusion 125. By setting the support rib 112 in an arc shape, the support rib 112 can not only play the role of supporting the protection door 120, but also further reduce the contact area between the support rib 112 and the protrusion 125, thereby reducing friction. The arc shape here is mainly compared to the contact surface of the support rib 112 and the protrusion 125 being a plane, the contact area between the arc-shaped support rib 112 and the protrusion 125 is smaller.

[0055] In some embodiments, limiting protrusions 1211 are provided on both sides of the main section 121 along the width direction Y, and limiting grooves 1111 are provided on both side walls of the placement groove 111. The limiting protrusions 1211 are configured to enter or exit the limiting grooves 1111 along the length direction X during the sliding process of the protection door 120. When the protection door assembly 100 is in a closed state, the limiting protrusions 1211 are located in the limiting grooves 1111, and play a role in limiting the protection door 120 in the length direction X and the thickness direction of the protection door 120. The limiting in the length direction X can prevent the elastic force of the elastic member 130 from being too large, resulting in excessive movement distance and failure to reset when the protection door 120 is reset; the limiting in the thickness direction can prevent the protection door 120 from falling out of the placement groove 111. When the protection door assembly 100 is in an open state, the limiting protrusions 1211 exit the limiting grooves 1111 as the protection door 120 moves.

[0056] The embodiment of the present application also provides a socket, which includes the protective door assembly 100 as described in any of the above embodiments. Because the socket is provided with the protective door assembly 100, it also has the structure and beneficial effects corresponding to the protective door assembly 100, which will not be described in detail here. The socket can be a three-hole socket, a five-hole socket, etc., without limitation. In this embodiment, the socket adopts a British standard three-hole socket.

[0057] The embodiment of the present application also provides an electronic device, which includes the protection door assembly 100 as described in any of the above embodiments. Because the electronic device is provided with the protection door assembly 100, it also has the corresponding structure and beneficial effects of the protection door assembly 100, which will not be described in detail here.
