Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

The disclosed embodiment provides a protection door mechanism, fig. 1 is a schematic structural view of the protection door mechanism, and referring to fig. 1, in this embodiment, the protection door mechanism includes a door seat 10 and a door body 20. The door seat 10 has at least two insertion holes 110 spaced apart from each other, the door body 20 is rotatably connected to the door seat 10, and the door body 20 is opposite to each insertion hole 110.

The door body 20 is configured to selectively expose each of the insertion holes 110 or block each of the insertion holes 110 by rotating the door body 20 with respect to the door base 10.

Fig. 2 is a schematic diagram illustrating the use of a protection door mechanism, which can be applied in a socket, and in an idle state (upper side of fig. 2), the door body 20 seals each jack 110, so as to avoid an electric shock accident caused by inserting a metal object into the jack 110 by a user. In the use state (lower side of fig. 2), the door body 20 rotates relative to the door seat 10, so that the door body 20 no longer blocks the insertion hole 110, but exposes the insertion hole 110. In this state, the pins of the plug can be inserted into the insertion holes 110 to take electricity. Also, since the door body 20 is rotated with respect to the door mount 10, not linearly moved, a moving space required for the door body 20 is effectively reduced, which is advantageous in a miniaturized design.

Fig. 3 is a schematic structural view of the door 20, and in combination with fig. 3, in this embodiment, the door 20 has a main body 210 and at least two shielding portions 220. Each shielding part 220 is connected with the main body 210 respectively, and is circumferentially arranged at intervals along the rotation axis 120 of the door body 20, each shielding part 220 corresponds to each jack 110 one by one, and each shielding part 220 is opposite to the corresponding jack 110. The main body 210 is rotatably coupled to the door base 10.

In the above implementation, the main body 210 provides a mounting base for the shielding portions 220, and each shielding portion 220 is disposed on the main body 210, so that the shielding portion 220 can rotate together with the main body 210, thereby blocking the corresponding jack 110, or exposing the corresponding jack 110.

Illustratively, the jacks 110 are the ground jack 111, the live jack 112 and the neutral jack 113, respectively, that is, the door mount 10 has three jacks 110, and accordingly, the door body 20 has three shielding portions 220 such that the shielding portions 220 are in one-to-one correspondence with the jacks 110.

In some examples, the protection door mechanism is suitable for a dc socket, then the ground jack 111 is a circular hole, the live jack 112 and the neutral jack 113 are elongated holes, and the live jack 112 and the neutral jack 113 are perpendicular to each other, and illustratively, the live jack 112 is arranged in a vertical direction, and the neutral jack 113 is arranged in a horizontal direction. That is, the ground wire insertion hole 111, the live wire insertion hole 112, and the neutral wire insertion hole 113 are arranged asymmetrically, and in this case, if the linear movement type protection door mechanism of the related art is used, a problem of a long movement path and a deviation of the movement path may occur. In addition, there is a problem that the ground wire jack 111, the live wire jack 112 and the neutral wire jack 113 are not synchronously opened or closed, so that interference occurs when the plug is plugged.

Of course, if the protection door mechanism is applicable to other sockets, the shape and arrangement of the jack 110 can be changed accordingly, which is not limited by the present disclosure.

With continued reference to fig. 3, in the present embodiment, a surface of the shielding portion 220 corresponding to the ground wire jack 111 facing away from the door seat 10 has a guide groove 230, and a groove bottom of the guide groove 230 is an inclined surface and is inclined along an extending direction of the ground wire jack 111.

In the above implementation, the guide groove 230 is opposite to the ground wire insertion hole 111, so that when the pin of the plug is inserted into the protection door mechanism, the ground wire pin of the plug will abut against the guide groove 230. Since the groove bottom of the guide groove 230 is inclined along the extending direction of the ground wire insertion hole 111, as the ground wire pins apply pressure to the guide groove 230, the guide groove 230 breaks down a part of the pressure applied by the ground wire pins perpendicular to the door seat 10, which is applied by the ground wire pins, into a component force pushing the door body 20 to rotate, thereby rotating the door body 20, so that the insertion holes 110 are exposed, and the pins of the plug can be inserted into the corresponding insertion holes 110.

Since the guide groove 230 is located on the shielding part 220, and the shielding part 220 rotates with respect to the pins when an external force is applied thereto, in order to prevent the guide groove 230 from interfering with the pins inserted into the guide groove 230 when rotating, the guide groove 230 is curved in a length direction, and the length direction of the guide groove 230 is coaxial with a rotation track of the door body 20. By the design, the pins can be effectively prevented from interfering with the guide grooves 230, and the reliability of the protective door assembly is improved.

Illustratively, the inner profile of the guide slot 230 matches the outer profile of the end of the ground pin. For example, if the protection door mechanism is applied to a dc socket, the end of the corresponding ground pin is hemispherical. Accordingly, the cross-sectional shape of the guide groove 230 should be hemispherical or arc-shaped. In this way, the pins can be more firmly inserted into the guide grooves 230 to stably drive the door 20 to rotate.

In the present embodiment, the height of the shielding part 220 having the guide groove 230 is greater than the height of the other shielding parts 220 in the direction perpendicular to the door mount 10.

In the above-described implementation, the guide groove 230 is enabled to be in contact with the ground pin first, while the remaining pins are not in contact with the corresponding shielding portions 220 due to the existence of the height difference. After the guide groove 230 contacts with the ground pin, the door body 20 starts to rotate until the jacks 110 are exposed, so that interference between the pins and the door body 20 caused by that the jacks 110 are not exposed in time by the door body 20 is avoided.

In some examples, the receptacles 110 are exposed simultaneously, i.e., to ensure that pins are successfully inserted into corresponding receptacles 110. In other examples, ground jack 111 may be exposed first, and live jack 112 and neutral jack 113 may be exposed later. In this way, the safety of the protection door mechanism can be further improved.

Generally, the length of the ground pin of the plug is longer than that of the other pins, so that when the plug is inserted, the ground pin firstly contacts the corresponding shielding portion 220, and the door body 20 is pushed to rotate by sliding on the guide groove 230 to open the ground jack 111, the live jack 112 and the neutral jack 113 on the door base 10, so that the three pins of the plug are smoothly inserted into the three jacks 110 of the protection door mechanism.

The shielding portions 220 of the door 20 corresponding to the live wire jack 112 (positive electrode jack) and the neutral wire jack 113 (negative electrode jack) are flat structures, i.e. the guide grooves 230 are not formed. Therefore, the protection door mechanism can be pushed open only by the ground pin, and the protection door mechanism cannot be turned open when foreign matter is inserted into the live wire insertion hole 112 and the neutral wire insertion hole 113.

Referring to fig. 1, in the present embodiment, the protection door mechanism further includes a reset member 30, and the reset member 30 is connected to the door base 10 and the door body 20, respectively.

The reset member 30 is configured such that when the reset member 30 is in the first state, the door 20 blocks each of the insertion holes 110 (upper side of fig. 2), and when the reset member 30 is subjected to an external force such that the reset member 30 is in the second state, the door 20 exposes each of the insertion holes 110 (lower side of fig. 2).

In the idle state, the reset element 30 is in the first state, and the door 20 can keep the plug holes 110 blocked under the action of the reset element 30. When the pins are inserted into the protection door mechanism, the pins push the door body 20 to rotate, and the reset piece 30 is subjected to external force, so that the first state is changed into the second state, and the door body 20 is exposed. When the pins are pulled out of the protection door mechanism, the external force applied to the reset piece 30 disappears, the reset piece 30 is changed from the second state to the first state, and the door body 20 plugs the socket again.

That is, the reset member 30 can enable the door body 20 to close the jack 110 in the idle state and expose the jack 110 in the use state, thereby improving the safety of the protection door mechanism.

Fig. 4 is a schematic structural diagram of the door 20, and the view angle of fig. 4 is opposite to that of fig. 3, and in combination with fig. 4, in this embodiment, a surface of the door 20 facing the door seat 10 has a receiving groove 240.

Fig. 5 is a schematic structural diagram of the door seat 10, and referring to fig. 5, a surface of the door seat 10 facing the door body 20 has a rotating shaft 120, and the rotating shaft 120 penetrates through the accommodating groove 240 and is rotatably inserted into the door body 20. The reset member 30 is a torsion spring, which is sleeved outside the rotating shaft 120 and is located in the accommodating groove 240.

In the above implementation manner, the accommodating groove 240 provides an accommodating space for the reset element 30, so that the reset element 30 can be located between the door body 20 and the door seat 10, and is more convenient to be connected with the door body 20 and the door seat 10 respectively. The reset piece 30 is designed to be a torsion spring, so that elasticity of the torsion spring can be utilized, the reset piece 30 has the capacity of resetting the door body 20, and the structure of the torsion spring can be utilized, so that the reset piece is sleeved outside the rotating shaft 120, the installation space is saved, and the structure for fixing the torsion spring is not needed to be additionally arranged. And, the torsion spring is sleeved outside the rotating shaft 120, so that the torsion spring can better apply acting force to the door body 20, and the door body 20 is pushed to rotate and reset.

In the present embodiment, the side of the door seat 10 facing the door body 20 has a first stopper 130, and the side of the door body 20 facing the door seat 10 has a slot 250. The first elastic arm of the torsion spring is propped against the first stop piece 130, and the second elastic arm of the torsion spring is inserted into the slot 250.

The first stop 130 provides a fixed basis for the first leg of the torsion spring and the slot 250 provides a fixed basis for the second leg of the torsion spring. In this way, the main spring part of the torsion spring is sleeved outside the rotating shaft 120, the first elastic arm of the torsion spring is fixed on the door seat 10, and the second elastic arm of the torsion spring is fixed on the door body 20, so that the torsion spring is sufficiently positioned, and elasticity can be stably applied between the door seat 10 and the door body 20.

It should be noted that the forms of the first spring arm and the second spring arm for fixing the torsion spring may be changed according to the requirement, for example, the first stopper 130 is disposed on the door body 20, and the slot 250 is disposed on the door seat 10, so that the fixing of the first spring arm and the second spring arm of the torsion spring can be achieved as well, which is not limited in the present disclosure.

Illustratively, the side of the door seat 10 facing the door body 20 has a buckle 150, the buckle 150 is spaced from the first stopper 130, and the first spring arm of the torsion spring is clamped between the first stopper 130 and the buckle 150. By the design, the torsion spring is more stable to install.

In the present embodiment, the side of the door seat 10 facing the door body 20 has a second stop 140, and when the reset member 30 is in the first state, the door body 20 abuts against the second stop 140.

In the above implementation manner, the second stop member 140 is used for limiting and stopping the door body 20, so that the door body 20 is prevented from rotating too much distance under the action of the reset member 30, and each shielding portion 220 can just block the corresponding jack 110. That is, by the second stopper portion, the reset piece 30 can be kept in the first state when no external force is applied.

The plug bush and the protection door mechanism 200 are respectively located in the housing 100, and the protection door mechanism 200 is located between the panel 1100 of the housing 100 and the plug bush.

Since the receptacle includes the protection door mechanism 200 shown in fig. 1-5, the receptacle has all the advantages of the protection door mechanism 200 shown in fig. 1-5 and will not be described in detail herein.
