DETAILED DESCRIPTION

[0035] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the contour of each component itself. The terms "first" and "second" are used to distinguish one element from another element and do not have order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.

[0037] According to an exemplary embodiment of the present disclosure, a power extraction device is provided, referring to Figures 1 to 3 As shown in the figure, one end of the power taking device is used to connect to the vehicle power taking port, and the other end is provided with a power taking panel 1, on which is provided a power taking socket 11 for inserting a load plug, and under which is provided a protective door 2 for opening or closing the power taking socket 11.

[0038] Through the above technical solution, in the power taking device provided by the present disclosure, when the protection door 2 closes the power taking socket 11, the setting of the protection door 2 can prevent the user from mistakenly inserting other conductive parts other than the load plug into the power taking socket 11, thereby preventing the user from mistakenly getting an electric shock, thereby improving the safety of the power taking device, that is, the safety of the power taking device of the present disclosure is relatively high. When it is necessary to use the power taking device to take electricity, the power taking device can be connected to the vehicle power taking port, the protection door 2 opens the power taking socket 11, and the load plug is inserted into the power taking socket 11.

[0039] It should be noted that the present disclosure does not limit the specific structure of the power extraction device, which will be described in detail in the following embodiments. In addition, when the user inserts the load plug into the power extraction socket 11, the user can push the protective door 2 to open the power extraction socket 11 through the pin of the load plug, which is not limited in the present disclosure.

[0040] In some embodiments of the present disclosure, reference Figures 1 to 3 As shown in , the power extraction device may include a sealed cavity assembly 3, in which a terminal accommodating cavity 31 and a protective door accommodating cavity 32 are formed, a power terminal 4 is provided in the terminal accommodating cavity 31, and a protective door 2 is provided in the protective door accommodating cavity 32, wherein the protective door accommodating cavity 32 is connected between the power extraction socket 11 and the terminal accommodating cavity 31. Here, by providing the sealed cavity assembly 3, the protective door 2 can be sealedly arranged in the protective door accommodating cavity 32, and the power terminal 4 can be sealedly arranged in the terminal accommodating cavity 31, thereby effectively improving the sealing performance of the power extraction device, which is beneficial for the use of the power extraction device in rainy and snowy weather. In addition, since the protection door accommodating chamber 32 is connected between the power socket 11 and the terminal accommodating chamber 31, the protection door 2 is set between the power socket 11 and the power terminal 4. In this way, when the protection door 2 opens the power socket 11, the load plug can be connected to the power terminal 4 through the protection door accommodating chamber 32. When the protection door 2 closes the power socket 11, the protection door 2 separates the power socket 11 from the terminal accommodating chamber 31, even if the power socket 11 and the terminal accommodating chamber 31 are not connected to each other, thereby preventing users from connecting other conductive components to the power terminal 4 and preventing users from accidentally getting electric shock.

[0041] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown in , the power taking device may include a first sealing ring 10, which is used to provide sealing at the connection between the power taking panel 1 and the sealed cavity assembly 3. In this way, the first sealing ring 10 can be used to prevent external rain or dust from entering the interior of the sealed cavity assembly 3 through the connection between the power taking panel 1 and the sealed cavity assembly 3, thereby further improving the sealing performance of the power taking device.

[0042] In some embodiments of the present disclosure, reference Figure 1and Figure 2 As shown in , the power extraction device may include a substrate 20 and a second sealing ring 30, the power terminal 4 is connected to the substrate 20, and the second sealing ring 30 is used to provide a seal at the connection between the sealed cavity component 3 and the substrate 20. In this way, the second sealing ring 30 can be used to prevent external rain or dust from entering the interior of the sealed cavity component 3 through the connection between the substrate 20 and the sealed cavity component 3, thereby further improving the sealing performance of the power extraction device.

[0043] In some embodiments of the present disclosure, reference Figures 1 to 3 As shown in , 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 may independently open or close the corresponding power socket 11, that is, the opening and closing of the corresponding power socket 11 by the N1 neutral socket protection door 21 and the opening and closing of the corresponding power socket 11 by the L1 live socket protection door 22 do not affect each other, thereby effectively reducing the insertion force required when the load plug is inserted into the power socket 11. Here, the N1 neutral terminal 41 and the L1 live terminal 42 are suitable for plugging with a two-pin load plug, and at this time, the N1 neutral terminal 41 and the L1 live terminal 42 can be arranged in parallel with each other.

[0044] In some embodiments, reference Figure 2 and Figure 3As shown in , the N1 neutral socket protection door 21 may include a first slider 211 and a first elastic member 212, the first elastic member 212 is arranged between the first slider 211 and the inner wall of the protection door accommodating chamber 32, and the L1 live socket protection door 22 may include a second slider 221 and a second elastic member 222, the second elastic member 222 is arranged between the second slider 221 and the inner wall of the protection door accommodating chamber 32, wherein the sliding of the first slider 211 and the sliding of the second slider 221 are independent of each other, that is, the sliding of the first slider 211 and the sliding of the second slider 221 do not affect each other, so that the N1 neutral socket protection door 21 can independently open or close the corresponding power socket 11, and similarly, the L1 live socket protection door 22 can independently open or close the corresponding power socket 11. Here, the first slider 211 and the second slider 221 can be arranged at intervals or staggered to achieve the sliding of the first slider 211 and the sliding of the second slider 221 are independent of each other, and the present disclosure does not limit this. In addition, when the two-pin load plug is plugged into the N1 neutral terminal 41 and the L1 live terminal 42, the two pins of the two-pin load plug can push the first slider 211 and the second slider 221 to slide respectively. At this time, the first elastic member 212 and the second elastic member 222 are both under pressure. When the two-pin load plug is unplugged from the power panel 1, the first elastic member 212 can push the first slider 211 to reset to close the corresponding power socket 11. Similarly, the second elastic member 222 can push the second slider 221 to reset to close the corresponding power socket 11. In addition, in some embodiments, reference Figure 2 As shown in , both the first slider 211 and the second slider 221 may have a guiding slope for abutting against the pin, so that the guiding slope may facilitate the sliding of the corresponding first slider 211 or the corresponding second slider 221.

[0045] In some embodiments of the present disclosure, reference Figures 1 to 3 As shown in , the power terminal 4 may include an N2 neutral terminal 43, an L2 live terminal 44 and a PE ground terminal 45, and the protection door 2 may include an N2 neutral socket protection door 23 and an L2 live socket protection door 24, and the N2 neutral socket protection door 23 and the L2 live socket protection door 24 may independently open or close the corresponding power socket 11, that is, the opening and closing of the corresponding power socket 11 by the N2 neutral socket protection door 23 and the opening and closing of the corresponding power socket 11 by the L2 live socket protection door 24 do not affect each other, thereby effectively reducing the insertion force required when the load plug is inserted into the power socket. Here, the N2 neutral terminal 43, the L2 live terminal 44 and the PE ground terminal 45 are suitable for plugging with a three-pin load plug, and at this time, the N2 neutral terminal 43 and the L2 live terminal 44 can be set at an angle. In addition, since the PE ground terminal 45 is used for grounding, the step of providing the protection door 2 at the power socket 11 corresponding to the PE ground terminal 45 can be omitted.

[0046] In some embodiments, reference Figure 2 As shown in , the N2 neutral socket protection door 23 may include a third slider 231 and a third elastic member 232, and the third elastic member 232 is arranged between the third slider 231 and the inner wall of the protection door accommodating chamber 32, and the L2 live socket protection door 24 may include a fourth slider 241 and a fourth elastic member 242, and the fourth elastic member 242 is arranged between the fourth slider 241 and the inner wall of the protection door accommodating chamber 32, wherein 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, so that the N2 neutral socket protection door 23 can independently open or close the corresponding power socket 11, and similarly, the L2 live socket protection door 24 can independently open or close the corresponding power socket 11. Here, the third slider 231 and the fourth slider 241 can be arranged at intervals or staggered to achieve the sliding of the third slider 231 and the sliding of the fourth slider 241 are independent of each other, and the present disclosure does not limit this. In addition, when the three-pin load plug is plugged into the N2 neutral terminal 43, the L2 live terminal 44 and the PE ground terminal 45, two of the pins of the three-pin load plug can respectively push the third slider 231 to slide and the fourth slider 241 to slide. At this time, the third elastic member 232 and the fourth elastic member 242 are both under pressure. When the three-pin load plug is pulled out of the power supply panel, the third elastic member 232 can push the third slider 231 to reset to close the corresponding power supply socket. Similarly, the fourth elastic member 242 can push the fourth slider 241 to reset to close the corresponding power supply socket 11.

[0047] In some embodiments, reference Figure 2 As shown in , the terminal accommodating chamber 31 may include a first sub-chamber 311 and a second sub-chamber 312, wherein the first sub-chamber 311 accommodates the N1 neutral terminal 41 and / or the N2 neutral terminal 43, and the second sub-chamber 312 accommodates the L1 live terminal 42 and / or the L2 live terminal 44, wherein the first sub-chamber 311 and the second sub-chamber 312 are separated from each other. In this way, the sealed isolation of 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 can be achieved, thereby, even if water enters the first sub-chamber 311 and / or the second sub-chamber 312, it can prevent the N1 neutral terminal 41 and / or the N2 neutral terminal 43 from accidentally forming an electrical connection with the L1 live terminal 42 and / or the L2 live terminal 44, causing leakage of the power taking device, so that such a setting can effectively improve the waterproof level of the power taking device and improve the reliability of the power taking device.

[0048] In some embodiments, reference Figure 2As shown in , the terminal accommodating chamber 31 may include a third sub-chamber 313, and the third sub-chamber 313 accommodates a PE ground terminal 45, wherein the third sub-chamber 313 is separated from the first sub-chamber 311 and the second sub-chamber 312. In this way, water that enters one of the first sub-chamber 311, the second sub-chamber 312 and the third sub-chamber 313 will not flow into the other two, thereby preventing the PE ground terminal 45 from accidentally forming an electrical connection with the N1 neutral terminal 41 and / or the N2 neutral terminal 43, or accidentally forming an electrical connection with the L1 live terminal 42 and / or the L2 live terminal 44, thereby further preventing leakage of the power taking device and improving the waterproof level and reliability of the power taking device.

[0049] In some embodiments, reference Figures 3 to 8 As shown in , the power taking device may include a switch 5, a switch trigger 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 taking socket 11, the switch 5 is closed by the switch trigger mechanism 6. When the protection door 2 closes the power taking socket 11, the switch 5 is opened by the switch trigger mechanism 6. In this way, the switch 5 and the protection door 2 can be linked by the switch trigger mechanism 6. Here, the switch trigger mechanism 6 can be constructed as a contact, and the contact is connected to the corresponding protection door 2 and the switch 5, which is not limited in the present disclosure.

[0050] The switch 5 may include an N1 neutral terminal switch 51 and an L1 live terminal switch 52, and the switch trigger mechanism 6 may include an N1 neutral terminal switch trigger mechanism 61 and an L1 live terminal switch trigger 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 grounding terminal 72, and the first identification resistor 81 and the second identification resistor 82 are connected in parallel with the N1 neutral terminal switch 51 and the L1 live terminal switch 52 respectively; wherein, when the opening and closing state of at least one of the N1 neutral terminal switch 51 and the L1 live terminal switch 52 changes, the working state of the power taking device changes. In this way, the change of the opening and closing state of the N1 neutral terminal switch 51 and / or the change of the opening and closing state of the L1 live terminal switch 52 can indicate the working state of the power taking device, for example, indicating the working state of the power taking device to the on-board charger (OBC), so as to facilitate the on-board charger to selectively supply power to the power taking device.

[0051] For example, in some embodiments, one end of the power taking device is plugged into the vehicle power taking port. When the N1 neutral terminal switch 51 is disconnected, the on-board charger can detect the first identification resistor 81. On the contrary, 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 live terminal switch 52 is disconnected, the on-board charger can detect the second identification resistor 82. On the contrary, when the L1 live 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. Therefore, the on-board charger can determine the working state of the power taking device by detecting the first identification resistor 81 and the second identification resistor 82, thereby selectively supplying power to the power taking device.

[0052] In some embodiments, reference Figures 3 to 8 As shown in, the switch 5 may include an N2 neutral line terminal switch 53 and an L2 live line terminal switch 54 connected in series between the charging confirmation terminal 71 and the grounding terminal 72, the switch trigger mechanism 6 includes an N2 neutral line terminal switch trigger mechanism 63 and an L2 live line terminal switch trigger mechanism 64, and the power taking device includes a third identification resistor 83 and a fourth identification resistor 84, and the third identification resistor 83 and the fourth identification resistor 84 are respectively connected in parallel with the N2 neutral line terminal switch 53 and the L2 live line terminal switch 54; wherein, when the opening and closing state of at least one of the N2 neutral line terminal switch 53 and the L2 live line terminal switch 54 changes, the working state of the power taking device changes. In this way, the changes in the opening and closing states of the N2 neutral terminal switch 53 and / or the opening and closing states of the L2 live terminal switch 54 can also be used to indicate the working state of the power taking device, for example, to indicate the working state of the power taking device to the on-board charger (OBC), thereby facilitating the on-board charger to selectively supply power to the power taking device, wherein the on-board charger can determine the working state of the power taking device by detecting the third identification resistor 83 and the fourth identification resistor 84.

[0053] In some embodiments, reference Figures 4 to 8 As shown in , the power taking device may include a neutral terminal and a live terminal. The above-mentioned N1 neutral terminal switch 51 and N2 neutral terminal switch 53 may be connected in series to the neutral terminal 73 , and the L1 live terminal switch 52 and L2 live terminal switch 54 may be connected in series to the live terminal 74 .

[0054] Optionally, refer to Figure 4As shown in , the working 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. In this way, when the power taking device is plugged into the vehicle power taking port, the on-board charger detects that the resistance value between the charging confirmation terminal 71 and the grounding terminal 72 is zero, thereby determining that the power taking device is in an idle state.

[0055] Optionally, refer to Figure 5 As shown in , the working state may include a first power-on state, in which the N1 neutral terminal switch 51 and the L1 live terminal switch 52 are closed, and the N2 neutral terminal switch 53 and the L2 live terminal switch 54 are disconnected. In this way, 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 grounding terminal 72, thereby judging that the two-pin load plug is plugged into the N1 neutral terminal 41 and the L1 live terminal 42, and the on-board charger cannot detect the third identification resistor 83 and the fourth identification resistor 84, thereby judging that the three-pin load plug is not plugged into 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, so that the two-pin load plug can take the power of the vehicle battery.

[0056] Optionally, refer to Figure 6 As shown in , the working state may include a second power-on state, in which the N1 neutral terminal switch 51 and the L1 live terminal switch 52 are disconnected, and the N2 neutral terminal switch 53 and the L2 live terminal switch 54 are closed. In this way, 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 grounding terminal 72, thereby judging that the three-pin load plug is plugged into the N2 neutral terminal 43, the L2 live terminal 44 and the PE ground terminal 45, and the on-board charger cannot detect the first identification resistor 81 and the second identification resistor 82, thereby judging that the two-pin load plug is not plugged into 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, so that the three-pin load plug can take the power of the vehicle battery.

[0057] Optionally, refer to Figure 7As shown in , the working state may include a first power-off state, in which three of 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 disconnected, and the other one is closed. 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 judging that other conductive parts other than the load plug are inserted into one of 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. At this time, the on-board charger is limited to supplying power to the power taking device, thereby preventing the user from accidentally getting an electric shock.

[0058] Optionally, refer to Figure 8 As shown in , the working state may include a second power-off state, in which three of 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 closed, and the other one is open. In this way, the on-board charger can detect three of the first identification resistor 81, the second identification resistor 82, the third identification resistor 83 and the fourth identification resistor 84, thereby judging that the load plug and other conductive components are inserted into three of 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. At this time, the on-board charger is limited to supplying power to the power taking device, thereby preventing the user from accidentally getting an electric shock.

[0059] 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, wherein 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. In this way, the on-board charger can avoid misjudging the working status of the power taking device. That is to say, the on-board charger can judge the working status of the power taking device by judging the total resistance value between the charging confirmation terminal 71 and the grounding terminal 72.
