[0036] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0037] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which this disclosure will not elaborate upon.

[0038] According to an exemplary embodiment of the present disclosure, a power-gathering device is provided. Referring to Figures 1 to 3, one end of the power-gathering device 100 is used to connect to the power-gathering port 210 of a vehicle 200, and the other end is provided with a power-gathering panel 1. The power-gathering panel 1 is provided with a power-gathering socket 11 for inserting a load plug, and a protective door 2 is provided under the power-gathering panel 1 for opening or closing the power-gathering socket 11.

[0039] Through the above technical solution, in the power-collecting device 100 provided in this disclosure, when the protective door 2 closes the power socket 11, the setting of the protective door 2 can prevent the user from accidentally inserting other conductive parts other than the load plug into the power socket 11, thereby preventing the user from accidentally getting an electric shock. This improves the safety of the power-collecting device 100, meaning the power-collecting device 100 of this disclosure has a high level of safety. When it is necessary to use the power-collecting device 100 to collect power, the power-collecting device 100 can be connected to the power port 210 of the vehicle 200, the protective door 2 can be opened, and the load plug can be inserted into the power socket 11.

[0040] It should be noted that this disclosure does not limit the specific structure of the power supply device 100, which will be described in detail in the following embodiments. Furthermore, when the user inserts the load plug into the power supply socket 11, the user can push the protective door 2 to open the power supply socket 11 through the pins of the load plug; this disclosure does not limit this capability.

[0041] In some embodiments of this disclosure, referring to Figures 1 to 3, the power-gathering device 100 may include a sealing cavity assembly 3. The sealing cavity assembly 3 forms a terminal receiving cavity 31 and a protective door receiving cavity 32. A power terminal 4 is disposed in the terminal receiving cavity 31, and a protective door 2 is disposed in the protective door receiving cavity 32. The protective door receiving cavity 32 communicates between the power-gathering socket 11 and the terminal receiving cavity 31. Here, by providing the sealing cavity assembly 3, the protective door 2 can be sealed within the protective door receiving cavity 32, and the power terminal 4 can be sealed within the terminal receiving cavity 31. This effectively improves the sealing performance of the power-gathering device 100, facilitating its use in rainy or snowy weather. Furthermore, since the protective door cavity 32 is connected between the power socket 11 and the terminal cavity 31, the protective door 2 is positioned between the power socket 11 and the power terminal 4. Thus, when the protective door 2 is open, the load plug can be connected to the power terminal 4 through the protective door cavity 32. When the protective door 2 is closed, the protective door 2 separates the power socket 11 from the terminal cavity 31. Even though the power socket 11 and the terminal cavity 31 are not connected to each other, it can prevent the user from connecting other conductive parts to the power terminal 4 and prevent the user from accidentally touching the electric shock.

[0042] In some embodiments of this disclosure, referring to Figures 1 and 2, the power-gathering device 100 may include a first sealing ring 10, which provides a seal at the connection between the power-gathering panel 1 and the sealing cavity assembly 3. Thus, the first sealing ring 10 prevents external rainwater or dust from entering the interior of the sealing cavity assembly 3 through the connection between the power-gathering panel 1 and the sealing cavity assembly 3, thereby further improving the sealing performance of the power-gathering device 100.

[0043] In some embodiments of this disclosure, referring to Figures 1 and 2, the power extraction device 100 may include a substrate 20 and a second sealing ring 30. A power terminal 4 is connected to the substrate 20, and the second sealing ring 30 provides a seal at the connection between the sealing cavity assembly 3 and the substrate 20. Thus, by utilizing the second sealing ring 30, external rainwater or dust can be prevented from entering the interior of the sealing cavity assembly 3 through the connection between the substrate 20 and the sealing cavity assembly 3, thereby further improving the sealing performance of the power extraction device 100.

[0044] In some embodiments of this disclosure, referring to Figures 1 to 3, the power terminal 4 may include an N1 neutral terminal 41 and an L1 live terminal 42, and the protection door 2 may include an N1 neutral socket protection door 21 and an L1 live socket protection door 22. The N1 neutral socket protection door 21 and the L1 live socket protection door 22 can independently open or close their respective power outlets 11. That is, the opening and closing of the N1 neutral socket protection door 21 on its corresponding power outlet 11 is independent of the opening and closing of the L1 live socket protection door 22 on its corresponding power outlet 11. Therefore, the insertion force required when inserting the load plug into the power outlet 11 can be effectively reduced. Here, the N1 neutral terminal 41 and the L1 live terminal 42 are suitable for connection to a two-pronged load plug. In this case, the N1 neutral terminal 41 and the L1 live terminal 42 can be arranged parallel to each other.

[0045] In some embodiments, referring to Figures 2 and 3, the N1 neutral wire socket protection door 21 may include a first slider 211 and a first elastic member 212. The first elastic member 212 is disposed between the first slider 211 and the inner wall of the protection door receiving cavity 32. The L1 live wire socket protection door 22 may include a second slider 221 and a second elastic member 222. The second elastic member 222 is disposed between the second slider 221 and the inner wall of the protection door receiving cavity 32. The sliding of the first slider 211 and the second slider 221 are independent of each other; that is, the sliding of the first slider 211 and the second slider 221 do not affect each other. Thus, the N1 neutral wire socket protection door 21 can independently open or close the corresponding power socket 11, and similarly, the L1 live wire socket protection door 22 can independently open or close the corresponding power socket 11. Here, the first slider 211 and the second slider 221 may be spaced apart or staggered to achieve independent sliding of the first slider 211 and the second slider 221. This disclosure does not limit this arrangement. Furthermore, when the two-pin load plug is inserted into the N1 neutral terminal 41 and the L1 live terminal 42, the two pins of the two-pin load plug can respectively push the first slider 211 and the second slider 221 to slide. At this time, both the first elastic element 212 and the second elastic element 222 are compressed. When the two-pin load plug is pulled out of the power supply panel 1, the first elastic element 212 can push the first slider 211 to reset and close the corresponding power supply socket 11. Similarly, the second elastic element 222 can push the second slider 221 to reset and close the corresponding power supply socket 11. In addition, in some embodiments, referring to FIG2, both the first slider 211 and the second slider 221 can have guide slopes for contacting the pins. In this way, the guide slopes can facilitate the sliding of the first slider 211 or the second slider 221.

[0046] In some embodiments of this disclosure, referring to Figures 1 to 3, the power terminal 4 may include an N2 neutral terminal 43, an L2 live terminal 44, and a PE ground terminal 45. The protection door 2 may include an N2 neutral socket protection door 23 and an L2 live socket protection door 24. The N2 neutral socket protection door 23 and the L2 live socket protection door 24 can independently open or close their respective power outlets 11. That is, the opening and closing of the N2 neutral socket protection door 23 on the corresponding power outlet 11 does not affect the opening and closing of the L2 live socket protection door 24 on the corresponding power outlet 11. Therefore, the insertion force required when inserting the load plug into the power outlet can be effectively reduced. Here, the N2 neutral terminal 43, the L2 live terminal 44, and the PE ground terminal 45 are suitable for connection with a three-prong load plug. In this case, the N2 neutral terminal 43 and the L2 live terminal 44 can be arranged at an angle. In addition, since the PE ground terminal 45 is used for grounding, the step of installing a protective door 2 at the power outlet 11 corresponding to the PE ground terminal 45 can be omitted.

[0047] In some embodiments, referring to FIG2, the N2 neutral wire socket protection door 23 may include a third slider 231 and a third elastic member 232, the third elastic member 232 being disposed between the third slider 231 and the inner wall of the protection door receiving cavity 32. The L2 live wire socket protection door 24 may include a fourth slider 241 and a fourth elastic member 242, the fourth elastic member 242 being disposed between the fourth slider 241 and the inner wall of the protection door receiving cavity 32. The sliding of the third slider 231 and the sliding of the fourth slider 241 are independent of each other; that is, the sliding of the third slider 231 and the sliding of the fourth slider 241 do not affect each other. Thus, the N2 neutral wire socket protection door 23 can independently open or close the corresponding power outlet 11, and similarly, the L2 live wire socket protection door 24 can independently open or close the corresponding power outlet 11. Here, the third slider 231 and the fourth slider 241 may be spaced apart or staggered to achieve independent sliding of the third slider 231 and the fourth slider 241; this disclosure does not limit this. In addition, when the three-pronged load plug is connected to the N2 neutral terminal 43, the L2 live terminal 44, and the PE ground terminal 45, two of the pins of the three-pronged load plug can push the third slider 231 and the fourth slider 241 to slide respectively. At this time, the third elastic element 232 and the fourth elastic element 242 are both pressed. When the three-pronged load plug is pulled out of the power supply panel, the third elastic element 232 can push the third slider 231 to reset to close the corresponding power supply socket 11. Similarly, the fourth elastic element 242 can push the fourth slider 241 to reset to close the corresponding power supply socket 11.

[0048] In some embodiments, referring to FIG2, the terminal receiving cavity 31 may include a first cavity 311 and a second cavity 312. The first cavity 311 accommodates the N1 neutral terminal 41 and / or the N2 neutral terminal 43, and the second cavity 312 accommodates the L1 live terminal 42 and / or the L2 live terminal 44, wherein the first cavity 311 and the second cavity 312 are separated from each other. In this way, the N1 neutral terminal 41 and / or the N2 neutral terminal 43 can be sealed and isolated from the L1 live terminal 42 and / or the L2 live terminal 44. Therefore, even if water enters the first cavity 311 and / or the second cavity 312, it can prevent accidental electrical connection between the N1 neutral terminal 41 and / or the N2 neutral terminal 43 and the L1 live terminal 42 and / or the L2 live terminal 44, thereby avoiding leakage of the power supply device 100. Thus, this configuration can effectively improve the waterproof rating of the power supply device 100 and improve the reliability of the power supply device 100.

[0049] In some embodiments, referring to FIG2, the terminal receiving cavity 31 may include a third sub-cavity 313, which houses the PE ground terminal 45. The third sub-cavity 313, the first sub-cavity 311, and the second sub-cavity 312 are all separated from each other. This prevents water entering one of the first sub-cavity 311, the second sub-cavity 312, or the third sub-cavity 313 from flowing into the other two. This avoids accidental electrical connections between the PE ground terminal 45 and the N1 neutral terminal 41 and / or the N2 neutral terminal 43, or between the PE ground terminal 45 and the L1 live terminal 42 and / or the L2 live terminal 44. This further prevents leakage of the power supply device 100 and improves its waterproof rating and reliability.

[0050] In some embodiments, referring to Figures 3 to 8, the power supply device 100 may include a switch 5, a switch triggering mechanism 6, a charging confirmation terminal 71, a grounding terminal 72, a first identification resistor 81, and a second identification resistor 82. When the protection door 2 opens the power supply socket 11, the switch 5 is closed by the switch triggering mechanism 6; when the protection door 2 closes the power supply socket 11, the switch 5 is opened by the switch triggering mechanism 6. In this way, the switch 5 and the protection door 2 can be linked together using the switch triggering mechanism 6. Here, the switch triggering mechanism 6 may be constructed as a contact that connects the corresponding protection door 2 and the switch 5 together; this disclosure does not limit this.

[0051] In some embodiments, referring to Figures 3 to 8, switch 5 may include an N1 neutral terminal switch 51 and an L1 live terminal switch 52, and switch triggering mechanism 6 may include an N1 neutral terminal switch triggering mechanism 61 and an L1 live terminal switch triggering mechanism 62. The N1 neutral terminal switch 51 and the L1 live terminal switch 52 are connected in series between the charging confirmation terminal 71 and the ground terminal 72. A first identification resistor 81 and a second identification resistor 82 are connected in parallel with the N1 neutral terminal switch 51 and the L1 live terminal switch 52, respectively. When the opening / closing state of at least one of the N1 neutral terminal switch 51 and the L1 live terminal switch 52 changes, the operating state of the power-collecting device 100 changes. Thus, by utilizing the change in the opening / closing state of the N1 neutral terminal switch 51 and / or the change in the opening / closing state of the L1 live terminal switch 52, the operating state of the power-collecting device 100 can be indicated, for example, for an on-board charger (OBC), thereby facilitating selective power supply from the on-board charger to the power-collecting device 100.

[0052] For example, in some embodiments, one end of the power-taking device 100 is plugged into the power port 210 of the vehicle 200. When the N1 neutral terminal switch 51 is open, the on-board charger can detect the first identification resistor 81. Conversely, when the N1 neutral terminal switch 51 is closed, the first identification resistor 81 is in a short-circuit state, and the on-board charger cannot detect the first identification resistor 81. Similarly, when the L1 power terminal switch 52 is open, the on-board charger can detect the second identification resistor 82. Conversely, when the L1 power terminal switch 52 is closed, the second identification resistor 82 is in a short-circuit state, and the on-board charger cannot detect the second identification resistor 82. Thus, the on-board charger can determine the operating state of the power-taking device 100 by detecting the first identification resistor 81 and the second identification resistor 82, thereby selectively supplying power to the power-taking device 100.

[0053] In some embodiments, referring to Figures 3 to 8, the switch 5 may include an N2 neutral terminal switch 53 and an L2 live terminal switch 54 connected in series between the charging confirmation terminal 71 and the ground terminal 72. The switch triggering mechanism 6 includes an N2 neutral terminal switch triggering mechanism 63 and an L2 live terminal switch triggering mechanism 64. The power-drawing device 100 includes a third identification resistor 83 and a fourth identification resistor 84, which are connected in parallel with the N2 neutral terminal switch 53 and the L2 live terminal switch 54, respectively. When the opening or closing state of at least one of the N2 neutral terminal switch 53 and the L2 live terminal switch 54 changes, the operating state of the power-drawing device 100 changes. In this way, by utilizing the change in the opening and closing state of the N2 neutral terminal switch 53 and / or the change in the opening and closing state of the L2 live terminal switch 54, the operating state of the power receiving device 100 can also be indicated, for example, to indicate the operating state of the power receiving device 100 to the on-board charger (OBC), thereby facilitating the on-board charger to selectively supply power to the power receiving device 100. The on-board charger can determine the operating state of the power receiving device 100 by detecting the third identification resistor 83 and the fourth identification resistor 84.

[0054] In some embodiments, referring to Figures 4 to 8, the power supply device 100 may include a neutral terminal and a live terminal. The N1 neutral terminal switch 51 and N2 neutral terminal switch 53 may be connected in series on the neutral terminal 73, and the L1 live terminal switch 52 and L2 live terminal switch 54 may be connected in series on the live terminal 74.

[0055] In some embodiments, referring to FIG4, the operating state may include an idle state, in which the N1 neutral terminal switch 51, the L1 live terminal switch 52, the N2 neutral terminal switch 53, and the L2 live terminal switch 54 are all disconnected. Thus, when the power supply device 100 is plugged into the power supply port 210 of the vehicle 200, the on-board charger detects the first identification resistor 81, the second identification resistor 82, the third identification resistor 83, and the fourth identification resistor 84 between the charging confirmation terminal 71 and the ground terminal 72, thereby determining that the power supply device 100 is in an idle state.

[0056] In some embodiments, referring to FIG5, the operating state may include a first energized state. In the first energized state, the N1 neutral terminal switch 51 and the L1 live terminal switch 52 are closed, while the N2 neutral terminal switch 53 and the L2 live terminal switch 54 are open. Thus, the on-board charger can detect the third identification resistor 83 and the fourth identification resistor 84 between the charging confirmation terminal 71 and the ground terminal 72, thereby determining that the two-pin load plug is connected to the N1 neutral terminal 41 and the L1 live terminal 42. Furthermore, the on-board charger cannot detect the first identification resistor 81 and the second identification resistor 82, thereby determining that the three-pin load plug is not connected to the N2 neutral terminal 43, the L2 live terminal 44, and the PE ground terminal 45. At this time, the on-board charger can supply power to the power-taking device 100, allowing the two-pin load plug to draw power from the vehicle battery.

[0057] In some embodiments, referring to FIG6, the operating state may include a second energized state. In the second energized state, the N1 neutral terminal switch 51 and the L1 live terminal switch 52 are open, while the N2 neutral terminal switch 53 and the L2 live terminal switch 54 are closed. Thus, the on-board charger can detect the first identification resistor 81 and the second identification resistor 82 between the charging confirmation terminal 71 and the ground terminal 72, thereby determining that the three-pronged load plug is connected to the N2 neutral terminal 43, the L2 live terminal 44, and the PE ground terminal 45. Furthermore, the on-board charger cannot detect the third identification resistor 83 and the fourth identification resistor 84, thereby determining that the two-pronged load plug is not connected to the N1 neutral terminal 41 and the L1 live terminal 42. At this time, the on-board charger can supply power to the power-taking device 100, allowing the three-pronged load plug to draw power from the vehicle battery.

[0058] In some embodiments, referring to FIG7, the operating state may include a first power-off state, in which three of the N1 neutral terminal switch 51, L1 live terminal switch 52, N2 neutral terminal switch 53, and L2 live terminal switch 54 are open, and the other is closed. In this way, the on-board charger can detect three of the first identification resistor 81, second identification resistor 82, third identification resistor 83, and fourth identification resistor 84, thereby determining that a conductive component other than the load plug is inserted into one of the N1 neutral terminal switch 51, L1 live terminal switch 52, N2 neutral terminal switch 53, and L2 live terminal switch 54. At this time, the on-board charger restricts power supply to the power-taking device 100, thereby preventing accidental electric shock to the user.

[0059] In some embodiments, referring to FIG8, the operating state may include a second power-off state, in which three of the N1 neutral terminal switch 51, L1 live terminal switch 52, N2 neutral terminal switch 53, and L2 live terminal switch 54 are closed, and the other is open. In this way, the on-board charger can detect one of the first identification resistor 81, the second identification resistor 82, the third identification resistor 83, and the fourth identification resistor 84, thereby determining that the load plug and other conductive components are inserted into three of the N1 neutral terminal switch 51, L1 live terminal switch 52, N2 neutral terminal switch 53, and L2 live terminal switch 54. At this time, the on-board charger restricts power supply to the power-taking device 100, thereby preventing accidental electric shock to the user.

[0060] In some embodiments, the sum of the resistance values ​​of the first identification resistor 81 and the second identification resistor 82 can be equal to the sum of the resistance values ​​of the third identification resistor 83 and the fourth identification resistor 84. In this case, the resistance values ​​of any two of the first identification resistor 81, the second identification resistor 82, the third identification resistor 83, and the fourth identification resistor 84 can be different. This can avoid misjudging the working state of the power taking device 100 by the on-board charger. In other words, the on-board charger can determine the working state of the power taking device 100 by judging the total resistance value between the charging confirmation terminal 71 and the grounding terminal 72.

[0061] According to a second aspect of this disclosure, a vehicle 200 is provided, including the power extraction device 100 as described above. The vehicle 200 possesses all the beneficial effects of the power extraction device 100 described above, which will not be elaborated upon herein.

In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0064] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
