As described above, in some conventional sockets, bodies of the sockets are small in size and convenient to be installed and used, but small structure may also bring some limitations, and it is difficult to dispose safety protection structures on the sockets.
Embodiments of the present disclosure provide a protective door for a socket and the socket. The protective door includes a base, a first sliding member, a second sliding member and a third sliding member, moving directions of the first sliding member and the third sliding member being perpendicular to each other, which may save space and help to install and arrange the protective door on the socket. Principles of the present disclosure will be described in detail below with reference to FIGS. 1 to 7.
As shown in FIGS. 1 to 3, a base 10 is a supporting structure of a protective door 100, and the protective door 100 may be installed on a body 210 of a socket. The base 10 may be installed on the socket by screw fastening, buckle connection or other mechanical fastening.
In some embodiments, the protective door 100 may be installed on the body 210 of DC socket. Hereinafter, a structure and working principle of the protective door 100 will be described in detail by taking the protective door 100 installed on the body 210 of the DC socket as an example. However, it should be understood that in other embodiments, the protective door 100 may also be installed on the body of other types of two-hole sockets, which is not intended to be limited in the present disclosure.
The base 10 is provided with a first through hole 11 and a second through hole 12. When the base 10 is installed on the body 210 of the DC socket, the first through hole 11 is aligned with a position of a first pin 211 of the body 210. A user may insert a terminal (e.g., a first electrode terminal) of a corresponding polarity of a DC plug into the first pin 211 through the first through hole 11. The second through hole 12 is aligned with a position of a second pin 212, and the user may insert the second electrode terminal of the DC plug into the second pin 212. In some embodiments, the first electrode terminal may be a negative terminal and the second electrode terminal may be a positive terminal.
As shown in FIGS. 1 to 3, a first sliding member 20 is disposed on a side of the base 10 facing away from the body 210 of the DC socket, and the first sliding member 20 may slide back and forth on the base 10 along a first direction. For example, if the first direction is a horizontal direction, the first sliding member 20 may slide horizontally on the base 10. The first sliding member 20 may block the second through hole 12 on the base 10 when the DC socket is not in use, so as to block the second pin 212 on the body 210, thereby preventing potential safety hazards caused by accidental contact.
A third through hole 21 is provided on the first sliding member 20, and the third through hole 21 may be aligned with the second through hole 12 on the base 10, thereby allowing a second electrode terminal of a power plug to pass through the third through hole 21 and the second through hole 12 and contact the second pin 212 on the body 210. When the first sliding member 20 slides to a blocking position, the third through hole 21 is staggered from the second through hole 12, and the first sliding member 20 may block the second through hole 12 and the second pin 212, which may prevent accidental contact.
As shown in FIGS. 1 to 3, a second sliding member 30 is disposed between the base 10 and the first sliding member 20, and the second sliding member 30 may also slide along the first direction. A fourth through hole 31 is provided on the second sliding member 30.
When the second sliding member 30 is in the blocking position, the fourth through hole 31 is staggered from the second through hole 12 on the base 10, and at this time, the second sliding member 30 blocks the second pin 212 on the body 210 of the DC socket, thereby increasing safety. When the second sliding member 30 slides to a relief position, the fourth through hole 31 is aligned with the second through hole 12 on the base 10, and at this time, the second electrode terminal of the DC power plug is allowed to pass through the second through hole 12 and be inserted into the second pin 212 on the body 210 of the socket, so that the power plug can work normally.
As shown in FIGS. 1 to 3, a third sliding member 40 is located at the base 10 and close to a side of the first sliding member 20. The third sliding member 40 may slide along a second direction perpendicular to the first direction. In this way, movement directions of the first sliding member 20 and the third sliding member 40 are different from each other, which reduces possibility of mutual interference, thereby helping to save space.
A transmission mechanism may be provided between the third sliding member 40 and the second sliding member 30, and the transmission mechanism may be, for example, a connecting rod, a gear, or a wedge-shaped structure, so that the third sliding member 40 may drive the second sliding member 30 to act together during sliding. That is, when the third sliding member 40 slides along the second direction, the third sliding member 40 drives the second sliding member 30 to switch between the blocking position and the relief position through the transmission mechanism. A fifth through hole 41 is provided on the third sliding member 40, and the fifth through hole 41 may be aligned with the first through hole 11 on the base 10, thereby allowing the first electrode terminal of the power plug to be inserted into the first pin 211 through the fifth through hole 41 and the first through hole 11.
When the second sliding member 30 is in the relief position, the third through hole 21 and the fourth through hole 31 are aligned with the second through hole 12 on the base 10, and at this time, the second electrode terminal of the power plug may be inserted into the second pin 212 on the body 210 of the socket through the third through hole 21, the fourth through hole 31 and the second through hole 12. In addition, the fifth through hole 41 is also aligned with the first through hole 11 on the base 10, so that the first electrode terminal of the power plug may be inserted into the first pin 211 on the body 210 of the socket through the fifth through hole 41 and the first through hole 11.
When the second sliding member 30 is in the blocking position, the third through hole 21 and the fourth through hole 31 are staggered from the second through hole 12 on the base 10, and at this time, the second electrode terminal of the power plug cannot contact the second pin 212 on the body 210 of the socket through the third through hole 21, the fourth through hole 31 and the second through hole 12, thereby preventing accidental electric shock. In this case, the fifth through hole 41 is also staggered from the first through hole 11 on the base 10, which may prevent the first electrode terminal of the power plug from contacting the first pin 211 on the body 210 of the socket, thereby further enhancing safety.
With this arrangement, the first sliding member 20 of the protective door 100 may achieve safety protection for the second pin 212, and the third sliding member 40 may achieve safety protection for the first pin 211. Meanwhile, the second sliding member 30 is linked with the third sliding member 40 to ensure that the first pin 211 and the second pin 212 are exposed or blocked at the same time, thereby improving safety of the protective door 100 and the DC socket. In addition, the movement directions of the first sliding member 20 and the third sliding member 40 are different from each other, which reduces the possibility of mutual interference, thereby helping to save space.
In some embodiments, as shown in FIGS. 2 and 3, an end of the third sliding member 40 facing towards the first sliding member 20 is provided with a groove 42. An end of the first sliding member 20 facing towards the third sliding member 40 is provided with a protrusion 23 adapted to be inserted into the groove 42 of the third sliding member 40.
When the second sliding member 30 is in the blocking position, the protrusion 23 may be inserted into the groove 42. Combination of the groove 42 and the protrusion 23 may prevent the third sliding member 40 from continuing to slide along the second direction, so that the entire protective door 100 is in a stable state.
When the third sliding member 40 slides, the third sliding member 40 drives the second sliding member 30 to move from the blocking position to the relief position through the transmission mechanism, thereby separating the groove 42 from the protrusion 23. When the third sliding member 40 continues to slide, the fourth through hole 31 may be aligned with the second through hole 12, and the fifth through hole 41 may also be aligned with the first through hole 11.
When the DC socket does not need to be used, the second sliding member 30 moves from the relief position back to the blocking position, and at this time, the protrusion 23 is inserted into the groove 42 again, so that movement of the third sliding member 40 may be limited, thereby returning the protective door 100 to an initial state.
In some embodiments, as shown in FIGS. 1 to 3, the second sliding member 30 and the third sliding member 40 may achieve mutual driving through contact between two inclined surfaces.
As shown in FIG. 1 to FIG. 3, an end of the third sliding member 40 facing towards the second sliding member 30 is provided with a first inclined surface 43. An end of the second sliding member 30 facing towards the third sliding member 40 is provided with a driving portion 32, and a side of the driving portion 32 facing towards the first inclined surface 43 is provided with a second inclined surface 33. The second inclined surface 33 is in contact with the first inclined surface 43 on the third sliding member 40 to transmit power, thereby realizing linkage between the second sliding member 30 and the third sliding member 40.
When the third sliding member 40 and the second sliding member 30 are installed on the base 10, the first inclined surface 43 and the second inclined surface 33 contact each other and abut against each other. When one of the third sliding member 40 and the second sliding member 30 begins to slide, interaction between the first inclined surface 43 and the second inclined surface 33 causes the other sliding member to also slide.
With a linkage structure between the second sliding member 30 and the third sliding member 40, it may be ensured that the first pin 211 and the second pin 212 are exposed or blocked at the same time, thereby improving the safety of the protective door 100 and the DC socket.
In some embodiments, as shown in FIGS. 1 and 3, a side of the first sliding member 20 facing towards the base 10 is provided with a sliding groove 22, and the second sliding member 30 is disposed in the sliding groove 22.
As shown in FIGS. 1 and 3, the second sliding member 30 may be accommodated in the sliding groove 22, so that the second sliding member 30 slides between the first sliding member 20 and the base 10. With this arrangement, the sliding groove 22 not only provides guidance and support for the second sliding member 30, but also limits its range of movement, ensuring that the second sliding member 30 can slide smoothly along the first direction.
In some embodiments, as shown in FIGS. 1 and 3, the protective door 100 further includes a first elastic member 51 and a second elastic member 52. The first elastic member 51 and the second elastic member 52 may drive the first sliding member 20, the second sliding member 30, and the third sliding member 40 to move to the blocking position.
As shown in FIGS. 1 and 3, an end of the first elastic member 51 is coupled to the base 10, and the other end is coupled to the first sliding member 20. The first elastic member 51 is configured to apply a force to the first sliding member 20 to stagger the third through hole 21 on the first sliding member 20 and the second through hole 12 on the base 10. That is, the first elastic member 51 can drive the first sliding member 20 to move to the blocking position, and at this time, the third through hole 21 is staggered from the second through hole 12, thereby preventing the second electrode terminal of the power plug from contacting the second pin 212 on the body 210 of the socket.
An end of the second elastic member 52 is coupled to the base 10, and the other end is coupled to the second sliding member 30. The second elastic member 52 is configured to apply a force to the second sliding member 30 to stagger the fourth through hole 31 and the second through hole 12. The second elastic member 52 may drive the second sliding member 30 to move to the blocking position, and at this time, the fourth through hole 31 is staggered from the second through hole 12, thereby preventing the second electrode terminal of the power plug from contacting the second pin 212 on the body 210 of the socket.
With this arrangement, when the user needs to use the DC socket, the DC plug needs to overcome forces of the first elastic member 51 and the second elastic member 52, so that the third through hole 21 and the fourth through hole 31 are aligned with the second through hole 12, and then the power plug is allowed to be inserted, thereby ensuring the safety of the DC socket.
In some embodiments, as shown in FIGS. 1 to 3, an end of the first sliding member 20 facing away from the third sliding member 40 is provided with a first protrusion 24, and an end of the second sliding member 30 facing away from the third sliding member 40 is provided with a second protrusion 34. A baffle 16 is disposed on a side of the first sliding member 20 facing away from the third sliding member 40, and the baffle 16 is fixed on the base 10. An end of the first elastic member 51 is coupled to the first protrusion 24, and the other end is coupled to the baffle 16. An end of the second elastic member 52 is coupled to the second protrusion 34, and the other end is coupled to the baffle 16.
With this arrangement, the baffle 16 may provide a fixed fulcrum for the first elastic member 51 and the second elastic member 52, and also provide a boundary for movement of the first sliding member 20 and the second sliding member 30, ensuring that the first sliding member 20 and the second sliding member 30 will not deviate from a track.
In some embodiments, as shown in FIGS. 1 to 3, a side of the first sliding member 20 facing towards the base 10 is provided with a first limiting groove 25, a side of the second sliding member 30 facing towards the base 10 is provided with a second limiting groove 35, and a side of the third sliding member 40 facing towards the base 10 is provided with a third limiting groove 44.
A first sliding rail 13 is provided on a side of the base 10 facing towards the first sliding member 20. The first sliding rail 13 may cooperate with the first limiting groove 25, thereby guiding the first sliding member 20 to slide along the first direction. A second sliding rail 14 is provided on a side of the base 10 facing towards the second sliding member 30. The second sliding rail 14 may cooperate with the second limiting groove 35, thereby guiding the second sliding member 30 to slide along the first direction. A third sliding rail 15 is provided on a side of the base 10 facing towards the third sliding member 40. The third sliding rail 15 may cooperate with the third limiting groove 44, thereby guiding the third sliding member 40 to slide along the second direction.
With this arrangement, limiting grooves are provided on a side of each sliding member facing towards the base 10, and corresponding sliding rails are provided on the base 10 to be cooperated with the limiting grooves, which may ensure that the first sliding member 20, the second sliding member 30 and the third sliding member 40 slide smoothly along a predetermined direction. At the same time, actions between sliding members may also be coordinated, so that the protective door 100 operates effectively.
In some embodiments, as shown in FIG. 2, the protective door 100 further includes a first limiting rib 17 and a second limiting rib 18 intersecting with each other, and the first limiting rib 17 and the second limiting rib 18 can abut against an outer side wall of the third sliding member 40 respectively to provide positioning for the third sliding member 40.
As shown in FIG. 2, the base 10 is provided with the first limiting rib 17 and the second limiting rib 18 perpendicular to each other. The first limiting rib 17 is in contact with the side wall of the third sliding member 40 and may limit the third sliding member 40 from sliding along the second direction. The second limiting rib 18 is disposed at an end of the third sliding member 40 and may limit a range of movement of the third sliding member 40 along the second direction. That is, the third sliding member 40 stops moving when abutting against the second limiting rib 18.
In some embodiments, as shown in FIG. 2, the first sliding member 20 further includes a first guide inclined surface 26, and the third sliding member 40 further includes a second guide inclined surface 45. The first guide inclined surface 26 and the second guide inclined surface 45 help the user operate the DC power plug to interface with the DC socket.
As shown in FIG. 2, the first guide inclined surface 26 is disposed at an edge of the third through hole 21 of the first sliding member 20. When the user attempts to insert the second electrode terminal of the DC plug into the third through hole 21, the first guiding inclined surface 26 may guide the second electrode terminal to be aligned with and inserted into the third through hole 21. The first guide inclined surface 26 helps to reduce friction during insertion, and ensure that the second electrode terminal can smoothly enter the third through hole 21. The second guide inclined surface 45 is disposed at an edge of the fifth through hole 41 of the third sliding member 40. When the user attempts to insert the first electrode terminal of the DC plug into the fifth through hole 41, the second guiding inclined surface 45 may guide the first electrode terminal to be aligned with and inserted into the fifth through hole 41.
With this arrangement, the first guide inclined surface 26 and the second guide inclined surface 45 may improve convenience of the user inserting the plug, thereby ensuring safety and reliability of power connection.
In some embodiments, as shown in FIGS. 4 and 5, the protective door 100 further includes a fixing member 60. The fixing member 60 is installed on the base 10, and may maintain a positional relationship between the first sliding member 20, the second sliding member 30, and the third sliding member 40 and the base 10, thereby preventing sliding members from being detached from the base 10. Secondly, the fixing member 60 may also connect the body 210 of the DC socket with a panel assembly 220.
As shown in FIGS. 4 and 5, the fixing member 60 includes a cover plate 61 and a side plate 62. The cover plate 61 provides a flat surface. A sixth through hole 63 and a seventh through hole 64 are provided on the cover plate 61. A position of the sixth through hole 63 corresponds to the first through hole 11 on the base 10. When the cover plate 61 is assembled with the base 10, the sixth through hole 63 is aligned with the first through hole 11, allowing the first electrode terminal of the power plug to pass through the sixth through hole 63 and be connected to the first pin 211 on the body 210 of the socket. A position of the seventh through hole 64 corresponds to the second through hole 12 on the base 10. When the cover plate 61 is assembled with the base 10, the seventh through hole 64 is aligned with the second through hole 12, allowing the second electrode terminal of the power plug to pass through the seventh through hole 64 and be connected to the second pin 212 on the body 210 of the socket.
The side plate 62 is disposed at a side of the cover plate 61 facing towards the base 10 and arranged around an edge of the cover plate 61.
