The end of the housing 1 away from the input end 49 is provided with a plug-in part 4 and a first plug-in hole 5. The output end 50 passes through the housing 1 and is inserted into the first plug-in hole 5. The plug-in part 4 is adapted to be plugged into the charging hole of a charging socket, and the output end 50 is adapted to be plugged into the socket current terminal of the charging socket.

[0041] The locking member 8 is rotatably mounted on the housing 1 about the first axis. The locking drive assembly can drive the locking member 8 from the unlock position to the locking position so that the locking member 8 is temporarily fixed to the charging socket. The unlock drive assembly can drive the locking member 8 from the locking position to the unlock position so that the locking member 8 is disengaged from the charging socket.

[0042] In this embodiment, the plug part 4 is used to plug into the charging hole of the charging socket so that the output terminal 50 is connected to the current terminal of the socket. The locking drive assembly drives the locking member 8 to switch to the locking position. When the locking member 8 is in the locking position, it can lock the plug part 4 in the charging hole. Only when the unlocking drive assembly drives the locking member 8 to switch to the unlocking position can the plug part 4 be pulled out of the charging hole to prevent hot plugging and unplugging.

[0043] In this embodiment, when the vehicle is charging, the first side 2 of the charging adapter is first plugged into the charging gun, so that the input terminal 49 is plugged into the charging gun current terminal of the charging gun. Then, the plug part 4 is plugged into the charging hole of the charging socket, so that the output terminal 50 is plugged into the socket current terminal. The locking drive assembly drives the locking member 8 to switch to the locking position. When the locking member 8 is in the locking position, it can lock the plug part 4 in the charging hole. Only when the unlocking drive assembly drives the locking member 8 to switch to the unlocking position can the plug part 4 be pulled out of the charging hole to prevent plugging and unplugging while the power is on.

[0044] In this embodiment, the charging adapter also includes a circuit board 51, a first signal output terminal 53, and a first signal input terminal 52.

[0045] In one embodiment, the charging adapter further includes a mounting base 36 mounted on the outer wall of the housing, and the mounting base 36 has a mounting cavity 40.

[0046] The locking member 8 has a driving part 13, a middle part and a locking part 18. The middle part is connected between the driving part 13 and the locking part 18. The middle part is rotatably assembled with the inner wall of the mounting cavity 40 along the first axis. The mounting base 36 is provided with a clearance hole 41. The locking part 18 extends out of the mounting base 36 through the clearance hole 41. The locking part 18 is provided with a hook 20.

[0047] The locking drive assembly can drive the locking member 8 to swing to a first angle. At the first angle, the locking member 8 is in the locked position and the hook 20 engages with the charging socket's locking hole. The unlocking drive assembly can drive the locking member 8 to swing to a second angle. At the second angle, the locking member 8 is in the unlocked position and the hook 20 disengages from the charging socket's locking hole.

[0048] In this embodiment, the mounting base 36 is mounted on the outer wall of the housing 1, and the mounting base 36 is provided with a mounting cavity 40. The mounting base 36 and the housing 1 form an installation space for the installation of the locking member 8.

[0049] In this embodiment, the connecting part 15 is provided with a rotating hole 16, and the locking member 8 also includes a rotating shaft 17, which is rotatably inserted in the rotating hole 16, and the first axis coincides with the axis of the rotating shaft 17.

[0050] In this embodiment, along the second direction, each of the opposite side walls of the mounting base 36 is provided with a through hole 39. The two ends of the rotating shaft 17 in the length direction are respectively inserted into the two through holes 39. Each end of the rotating shaft 17 is provided with a mounting hole. By inserting screws through the outside of the mounting base 36 and the mounting holes, the two ends of the rotating shaft 17 are fixed on the mounting base 36, thereby realizing the anti-rotation assembly between the rotating shaft 17 and the mounting base 36, so that the connecting part 15 can rotate around the rotating shaft 17.

[0051] In this embodiment, a hook 20 is provided on the lower side of the latching part 18. When the locking member 8 is in the locked position, the hook 20 can be inserted into the latching hole in the charging hole of the charging socket to realize the latching and locking of the locking member 8 and the latching hole on the charging socket.

[0052] In this embodiment, the unlocking drive mechanism drives the locking member 8 to rotate from the first angle to the second angle, and the locking drive assembly drives the locking member 8 to rotate from the second angle to the first angle, thereby making the locking member 8 move between the locked position and the unlocked position. The structure is simple and easy to design.

[0053] In one embodiment, the locking drive assembly includes an elastic element 9 connected between the latching portion 18 and the inner wall of the mounting base 36, and the elastic element 9 is used to drive the latching portion 18 to move toward the housing 1.

[0054] In this embodiment, the elastic element 9 is a first spring 10 extending in the vertical direction.

[0055] In this embodiment, the upper surface of the snap-fit ​​part 18 is provided with an abutment groove 19, the top wall of the mounting cavity 40 is provided with a first mounting post 42, the upper end of the first spring 10 is sleeved on the first mounting post 42, and the bottom end of the first spring 10 abuts against the bottom wall of the abutment groove 19.

[0056] In this embodiment, the first spring 10 drives the latching part 18 to swing downward, causing the locking member 8 to rotate to a first angle, causing the hook 20 on the latching part 18 to move downward and engage in the latching hole of the charging socket. This achieves locking between the charging socket and the charging adapter.

[0057] In one embodiment, the end of the driving part 13 away from the latching part 18 is provided with a first driving surface 14, and the distance between the end of the first driving surface 14 near the latching part 18 and the housing 1 is greater than the distance between the end of the first driving surface 14 away from the latching part 18 and the housing 1.

[0058] The unlocking drive assembly includes a locking block 7, which is located in the mounting cavity 40. The side of the locking block 7 facing the first drive surface 14 is provided with a second drive surface 24. The distance between the end of the second drive surface 24 near the locking member 8 and the housing 1 is greater than the distance between the end of the second drive surface 24 away from the locking member 8 and the housing 1. The second drive surface 24 abuts against the first drive surface 14.

[0059] Along the first direction, the locking block 7 can slide between a first position and a second position. In the second position, the second driving surface 24 forces the locking member 8 to swing to a second angle. In the first position, the locking drive lock member 8 swings to a first angle.

[0060] In this embodiment, the outer wall of the housing 1 is provided with a mounting groove 12, and the mounting base 36 can be detachably installed in the mounting groove 12.

[0061] In this embodiment, the mounting base 36 is provided with two baffles 43 located in the mounting cavity 40. The two baffles 43 are spaced apart along a second direction, which is perpendicular to the length direction of the main body terminal 48. A sliding groove 44 is formed between the two baffles 43. The locking block 7 is slidably assembled in the sliding groove 44. Along the first direction, the locking block 7 can slide between a first position and a second position in the sliding groove 44.

[0062] In this embodiment, since the rotating shaft 17 is fixed on the mounting base 36 and the connecting part 15 is sleeved on the rotating shaft 17, the locking member 8 forms a seesaw-like structure. When the locking block 7 slides from the first position to the second position (sliding to the left), the first driving surface 14 gradually switches from contacting the left end (higher end) of the second driving surface 24 on the locking block 7 to contacting the right end (lower end) of the second driving surface 24 on the locking block 7, forcing the driving part 13 to swing downward and the locking part 18 to swing upward, so that the locking member 8 rotates to the second angle, thereby causing the hook 20 to disengage from the charging socket's locking hole and unlocking is achieved.

[0063] When the locking block 7 slides from the second position to the first position (sliding to the right), under the action of the elastic member 9 driving the locking part 18, the locking part 18 swings downward, causing the driving part 13 to lift upward. The first driving surface 14 gradually switches from contacting the right end (lower end) of the second driving surface 24 on the locking block 7 to contacting the left end (higher end) of the second driving surface 24 on the locking block 7, causing the locking member 8 to rotate to the first angle, so that the hook 20 engages in the card hole of the charging socket, thereby locking the plug part 4 and the charging socket.

[0064] In this embodiment, the drive unit 13 is driven to swing by the locking block 7, which saves space and facilitates manufacturing.

[0065] In one embodiment, the locking block 7 is provided with a guide groove 23 on the side facing the driving part 13, and the bottom wall of the guide groove forms a second driving surface 24. The end of the driving part 13 near the locking block 7 is inserted into the guide groove 23.

[0066] In this embodiment, the end of the drive unit 13 near the locking block 7 is engaged in the guide groove 23. The guide groove 23 can guide the drive unit 13 and prevent the first drive surface 14 of the drive unit 13 from disengaging from the second drive surface 24.

[0067] In one embodiment, the drive assembly further includes a drive member 6, which is capable of driving the locking block 7 to slide between a first position and a second position.

[0068] In this embodiment, the locking block 7 is slidable by the driving component 6, which facilitates operation.

[0069] In one embodiment, the driving member 6 includes a pushing part 21 and a transition part 22. The mounting base 36 is provided with a driving groove 37 on the side facing away from the housing 1. The bottom wall of the driving groove 37 is provided with a first through hole 38. The first through hole 38 is an elongated hole extending along a first direction. The transition part 22 passes through the first through hole 38. The end of the transition part 22 near the housing 1 is connected to the locking block 7, and the end of the transition part 22 away from the housing 1 is connected to the pushing part 21.

[0070] The pusher 21 can slide in the drive groove 37 along the first direction, and the pusher 21 drives the transition section 22 to move along the first direction.

[0071] In this embodiment, the pushing part 21 is slidably mounted in the driving groove 37, the bottom of the pushing part 21 is connected to the top of the transition part 22 through the first through hole 38, and the bottom of the transition part 22 is connected to the first driving member 6.

[0072] When the pushing part 21 moves in the drive groove 37, the pushing part 21 drives the transition part 22 to move along the first direction, so that the transition part 22 drives the first drive member 6 to slide along the first direction. The pushing part 21 is exposed outside the mounting base 36 for easy operation by the staff.

[0073] In one embodiment, the locking mechanism further includes a stop beam 55, which is connected to the housing 1. The stop beam 55 is provided with a second through hole 56, and the snap-fit ​​part 18 passes through the second through hole 56. The inner wall of the second through hole 56 facing the housing 1 is engaged with the side of the snap-fit ​​part 18 facing away from the housing 1.

[0074] In this embodiment, the stop beam 55 is used to stop the latching part 18, thereby limiting the locking member 8 in the vertical direction, thereby restricting the position of the locking block 7 in the first direction and preventing the first driving surface 14 from disengaging from the locking block 7.

[0075] In one embodiment, the unlocking drive component further includes a locking mechanism capable of locking the lock block 7 in a first position or a second position.

[0076] In this embodiment, the bottom wall of the mounting groove 12 is also provided with a first locking groove 46 and a second locking groove 47 spaced apart. The first locking groove 46 is located below the locking block 7 when it is in the first position, and the second locking groove 47 is located below the locking block 7 when it is in the second position.

[0077] In this embodiment, the locking mechanism includes a locking pin 29 and a second spring 28.

[0078] In this embodiment, the locking pin 29 extends vertically, with its top end inserted into the lock hole 25 located at the bottom of the locking block 7, and its bottom end exposed outside the lock hole 25. A stop ring platform 30 is provided on the outer circumferential surface of the locking pin 29.

[0079] In this embodiment, the locking structure further includes a stop member 31. The bottom of the locking block 7 is provided with a stop groove 26, and the stop member 31 is slidably assembled in the stop groove 26. A slot 27 is provided on the side wall of the stop groove 26. The stop member 31 has a stop portion 32 and an elastic arm 33. A locking block 34 is provided on the elastic arm 33, and the locking block 34 engages with the slot 27 to prevent the stop member 31 from dislodging from the guide groove 23. The stop portion 32 seals the bottom opening of the lock hole 25, and a stop hole 35 is provided on the stop portion 32. The bottom end of the locking pin 29 passes through the stop hole 35, and the lower surface of the stop ring 30 of the locking pin 29 engages with the upper surface of the stop portion 32 to prevent the locking pin 29 from dislodging from the lock hole 25.

[0080] In this embodiment, the top end of the spring abuts against the top wall of the lock hole 25, and the bottom end of the spring is sleeved on the locking pin 29, with its bottom end abutting against the upper surface of the stop ring platform 30, which can drive the locking pin 29 to move closer to the housing 1.

[0081] In this embodiment, the locking pin 29 and the locking block 7 operate together, and the first locking groove 46 and the second locking groove 47 are connected. In the first position, the bottom end of the locking pin 29 slides into the first locking groove 46, and the locking pin 29 cooperates with the first locking groove 46. Without external force, the locking pin 29 cannot be dislodged from the first locking groove 46, thereby locking the locking block 7 in the first position. In the second position, the bottom end of the locking pin 29 slides into the second locking groove 47. Without external force, the locking pin 29 cannot be dislodged from the second locking groove 47, thereby locking the locking block 7 in the second position.

[0082] In one embodiment, the unlocking drive assembly further includes a locking rod 54. The mounting base 36 has a third through hole 45 on the side opposite to the plug-in portion 4. The locking rod 54 extends along a first direction. One end of the locking rod 54 is connected to the side of the locking block 7 opposite to the snap-fit ​​portion 18. The other end of the locking rod 54 extends out of the third through hole 45. The locking rod 54 is used to lock and cooperate with the electronic lock mechanism of the charging gun.

[0083] In this embodiment, the locking rod 54 is connected to the locking block 7 and slides with the locking block 7.

[0084] In this embodiment, when the locking block 7 slides to the first position, the locking rod 54 extends from the mounting base 36 through the third through hole 45. When the vehicle is charging, the locking rod 54 can lock and cooperate with the electronic locking mechanism on the charging gun. The cooperation between the electronic locking mechanism and the locking rod 54 is existing technology and will not be described in detail here.

[0085] In one embodiment, the charging adapter also includes a micro switch, which is installed in the mounting groove 12 and faces the side where the locking block 7 is located. The bottom wall of the mounting groove 12 is provided with a fourth through hole 11. The micro switch is electrically connected to the circuit board 51 inside the housing 1 through a cable passing through the fourth through hole 11. When the micro switch is open, the circuit between the input terminal 49 and the output terminal 50 is connected. When the micro switch is closed, the circuit between the input terminal 49 and the output terminal 50 is disconnected.

[0086] In this embodiment, the micro switch is a normally open switch. When the locking block 7 slides to the first position, the first driving member 6 disengages from the micro switch, thereby opening the micro switch. When the locking block 7 slides to the second position, the locking block 7 presses the micro switch, thereby closing the micro switch.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The charging adapter provided in this embodiment works on the following principle:

[0089] When the vehicle is charging, first push the pusher 21 towards the plug-in part 4 to move the locking block 7 to the second position, so that the locking member 8 is in the unlocked state.

Then, plug the plug-in part 4 of the charging adapter into the charging hole of the charging socket, so that the output terminal 50 is plugged into the charging gun current terminal and the first signal output terminal 53 is plugged into the charging gun signal terminal. Then, push the pusher 21 away from the plug-in part 4 to move the locking block 7 to the first position, so that the buckle on the latching part 18 is latched into the latching hole of the charging socket. At the same time, the locking rod 54 extends out of the mounting base 36 and locks into the electronic lock mechanism of the charging gun. The locking block 7 moves away from the micro switch, thereby opening the micro switch and connecting the circuit between the charging gun and the charging socket.

[0090] After the vehicle is fully charged, push the pusher 21 toward the plug 4 to move the locking block 7 to the second position, so that the locking member 8 is in the unlocked state, and the hook 20 of the latching part 18 disengages from the latching hole of the charging socket. The locking rod 54 retracts into the mounting base 36. At the same time, the locking block 7 presses the micro switch to close, thereby turning off the micro switch and disconnecting the circuit between the charging gun and the charging socket. Then, pull the charging adapter out of the charging socket and then pull the charging gun out of the charging adapter.

[0091] According to the charging adapter provided in this embodiment of the present invention, the plug part 4 is used to be plugged into the charging hole of the charging socket so that the output end 50 is plugged into the socket current terminal. The locking drive assembly drives the locking member 8 to switch to the locking position. When the locking member 8 is in the locking position, it can lock the plug part 4 in the charging hole. Only when the unlocking drive assembly drives the locking member 8 to switch to the unlocking position can the plug part 4 be pulled out from the charging hole to prevent hot plugging and unplugging.
