[0039] like Figures 1 to 10 As shown, an embodiment of the present invention provides a charging adapter, including a housing 1, a main terminal 35 and a locking assembly. The main terminal 35 has an input terminal 36 and an output terminal 37. The housing 1 has a first side 2 and a second side 3 opposite to each other along a first direction. The input terminal 36 is exposed on the first side 2 and is adapted to be plugged into the charging gun current terminal of a charging gun. The second side 3 is provided with a plug-in portion 4 and a first plug-in hole 5. The output terminal 37 passes through the housing 1 and is inserted into the first plug-in hole 5. The plug-in portion 4 is adapted to be plugged into the charging hole of a charging socket and the output terminal 37 is adapted to be plugged into the socket current terminal of the charging socket.

[0040] The locking component has a locked state and an unlocked state. In the locked state, the locking component locks the plug part 4 in the charging port. In the unlocked state, the locking component releases the plug part 4.

[0041] In this embodiment, when the vehicle is charging, the second side 3 of the charging adapter is first plugged into the charging gun, so that the input end 36 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 end 37 is plugged into the socket current terminal. The locking component can lock the plug part 4 in the charging hole in the locked state. Only when the locking component is switched to the unlocked state can the plug part 4 be pulled out of the charging hole to prevent plugging and unplugging while the power is on.

[0042] In this embodiment, the charging adapter also includes a circuit board 34, a first signal output terminal 39, and a first signal input terminal 38. The circuit board 34 is installed inside the housing 1. The first signal output terminal 39 and the first signal input terminal 38 are electrically connected to the circuit board 34. The first signal input terminal 38 and the input terminal 36 are exposed on the first side 2. The first signal output terminal 39 is exposed on the plug-in portion 4. The first signal input terminal 38 is plugged into the charging gun signal terminal of the charging gun. The first signal output terminal 39 is plugged into the socket signal terminal of the charging socket.

[0043] In one embodiment, the locking assembly includes a locking member 9 and a driving mechanism. The locking member 9 is rotatably mounted on the outer wall of the housing 1 along a first axis. The driving mechanism drives the locking member 9 to rotate between a locked position and an unlocked position. In the locked position, the locking member 9 engages with the locking hole of the charging socket. In the unlocked position, the locking member 9 disengages from the locking hole of the charging socket.

[0044] In this embodiment, the driving mechanism drives the locking member 9 to rotate between the locked position and the unlocked position, which facilitates switching between the locked and unlocked states and makes control easier.

[0045] In one embodiment, the charging adapter further includes a mounting base 26, which is mounted on the outer wall of the housing 1 and has a mounting cavity 31 inside.

[0046] The locking member 9 has a driving part 15, a middle part and a locking part 18. The middle part is connected between the driving part 15 and the locking part 18. The middle part is rotatably assembled with the inner wall of the mounting cavity 31 along the first axis. The mounting base 26 is provided with a locking hole 30. The locking part 18 extends out of the mounting base 26 through the locking hole 30. The locking part 18 is provided with a hook 19.

[0047] The drive mechanism drives the drive unit 15 to swing between a first angle and a second angle. At the first angle, the locking member 9 is in the locked position and the hook 19 engages with the charging socket's locking hole. At the second angle, the locking member 9 is in the unlocked position and the hook 19 disengages from the charging socket's locking hole.

[0048] In this embodiment, the mounting base 26 is mounted on the outer wall of the housing 1, and the mounting base 26 is provided with a mounting cavity 31. The mounting base 26 and the housing 1 form an installation space for mounting the locking member 9 and the drive mechanism.

[0049] In this embodiment, the connecting part 17 is provided with a rotating hole 22, and the locking member 9 also includes a rotating shaft 40, which is rotatably inserted in the rotating hole 22, and the axis of the rotating shaft 40 coincides with the first axis.

[0050] In this embodiment, along the second direction, each of the opposite side walls of the mounting base 26 is provided with a through hole 29. The two ends of the rotating shaft 40 in the length direction are respectively inserted into the two through holes 29. Each end of the rotating shaft 40 is provided with a mounting hole. By inserting screws through the outside of the mounting base 26 and the mounting holes, the two ends of the rotating shaft 40 are fixed on the mounting base 26, thereby realizing the anti-rotation assembly between the rotating shaft 40 and the mounting base 26, so that the connecting part 17 can rotate around the rotating shaft 40.

[0051] In this embodiment, a hook 19 is provided on the lower side of the latching part 18. When the locking member 9 is in the locked position, the hook 19 can be inserted into the card hole in the charging hole of the charging socket to realize the latching and locking of the locking member 9 and the card hole.

[0052] In this embodiment, the drive mechanism drives the drive unit 15 to swing between a first angle and a second angle, thereby causing the locking member 9 to move between the locked position and the unlocked position. The structure is simple and easy to design.

[0053] In one embodiment, the driving part 15 is provided with a driving hole 16, and the distance between the end of the driving hole 16 near the snap-fit ​​part 18 and the housing 1 is greater than the distance between the end of the driving hole 16 away from the snap-fit ​​part 18 and the housing 1.

[0054] The drive mechanism includes a first drive member 8 and a locking pin 23. The first drive member 8 is located in the mounting cavity 31, and the locking pin 23 extends along the second direction. One end of the locking pin 23 is connected to the first drive member 8, and the other end of the locking pin 23 is inserted into the drive hole 16.

[0055] The first driving member 8 can slide along a first direction between a first position and a second position. In the first position, the locking pin 23 drives the driving part 15 to swing to a first angle, and in the second position, the locking pin 23 drives the driving part 15 to swing to a second angle.

[0056] The second direction is perpendicular to the first direction.

[0057] In this embodiment, the first direction is the length direction of the main body terminal 35, and the second direction is perpendicular to the first direction.

[0058] In this embodiment, the mounting base is provided with two baffles 32 located in the mounting cavity 31. The two baffles 32 are spaced apart along a second direction, which is perpendicular to the length direction of the main body terminal 35. A sliding groove 33 is formed between the two baffles 32. The first driving member 8 is slidably assembled in the sliding groove 33. Along the first direction, the first driving member 8 can slide between a first position and a second position in the sliding groove 33.

[0059] In this embodiment, the locking pin 23 on the first driving member 8 is inserted into the driving hole 16. Since the rotating shaft 40 is fixed on the mounting base 26 and the connecting part 17 is sleeved on the rotating shaft 40, the locking member 9 forms a structure similar to a seesaw. When the first driving member 8 slides from the first position to the second position, the locking pin 23 moves from the right (lower) end of the driving hole 16 to the left (higher) end. At this time, the locking pin 23 cooperates with the lower hole wall of the driving hole 16 to force the driving part 15 to swing downward to the second angle, thereby causing the locking part 18 to swing upward, thereby causing the hook 19 to disengage from the locking hole of the charging socket and achieve unlocking.

[0060] When the first driving member 8 slides from the second position to the first position, the locking pin 23 moves from the left (higher) end of the driving hole 16 to the right (lower) end. At this time, the locking pin 23 cooperates with the upper hole wall of the driving hole 16 to force the driving part 15 to rise to the first angle, thereby causing the locking part 18 to swing downward, so that the hook 19 is locked in the locking hole of the charging socket, thereby locking the plug part 4 and the charging socket.

[0061] In this embodiment, the first driving member 8 drives the driving part 15 to swing, which saves space and facilitates manufacturing.

[0062] In one embodiment, the driving mechanism further includes a second driving member 12, which is capable of driving the first driving member 8 to slide between a first position and a second position.

[0063] The first drive component 8 is slidable by the second drive component 12, which facilitates operation.

[0064] In one embodiment, the second driving member 12 includes a pushing part 24 and a transition part 25. The mounting base 26 is provided with a driving groove 27 on the side facing away from the housing 1. The bottom wall of the driving groove 27 is provided with a first through hole 28. The first through hole 28 is an elongated hole extending along a first direction. The transition part 25 passes through the first through hole 28. The end of the transition part 25 near the housing 1 is connected to the first driving member 8, and the end of the transition part 25 away from the housing 1 is connected to the pushing part 24.

[0065] The pusher 24 can slide in the drive groove 27 along the first direction, and the pusher 24 drives the transition section 25 to move along the first direction.

[0066] In this embodiment, the pushing part 24 is slidably mounted in the driving groove 27, and the bottom of the pushing part 24 is connected to the top of the transition part 25 through the first through hole 28. The bottom of the transition part 25 is connected to the first driving member 8.

[0067] When the pushing part 24 moves in the drive groove 27, the pushing part 24 drives the transition part 25 to move along the first direction, so that the transition part 25 drives the first drive member 8 to slide along the first direction. The pushing part 24 is exposed outside the mounting base 26 for easy operation by the staff.

[0068] In one embodiment, the locking assembly further includes an elastic element 21 connected between the latching portion 18 and the housing 1, the elastic element 21 being used to drive the latching portion 18 to move away from the housing 1.

[0069] In this embodiment, the outer wall of the housing 1 is provided with a mounting groove 14, the mounting base 26 is detachably installed in the mounting groove 14, the bottom surface of the snap-fit ​​part 18 is provided with a first mounting post 20, the mounting groove 14 is provided with a second mounting post, the elastic element 21 is a spring, the top end of the spring is sleeved on the first mounting post 20, the bottom end of the spring is sleeved on the second mounting post, and the spring can drive the snap-fit ​​part 18 to swing upward to assist in unlocking.

[0070] In one embodiment, the locking assembly further includes a stop beam 6, which is connected to the housing 1. The stop beam 6 is provided with a second through hole 7, and the snap-fit ​​part 18 passes through the second through hole 7. The inner wall of the second through hole 7 facing the housing 1 is engaged with the side of the snap-fit ​​part 18 facing away from the housing 1.

[0071] In this embodiment, the stop beam 6 is used to stop the latching part 18, thereby limiting the locking member 9 in the vertical direction, thereby restricting the position of the first driving member 8 in the first direction and preventing the locking pin 23 from disengaging from the driving hole 16.

[0072] In one embodiment, the locking assembly further includes a locking rod 13. The mounting base 26 has a third through hole 43 on the side opposite to the insertion part 4. The locking rod 13 extends along a first direction. One end of the locking rod 13 is connected to the side of the first driving member 8 opposite to the snap-fit ​​part 18. The other end of the locking rod 13 extends out of the third through hole 43. The locking rod 13 is used to lock and cooperate with the electronic lock mechanism of the charging gun.

[0073] In this embodiment, the locking rod 13 is connected to the first driving member 8 and slides with the first driving member 8.

[0074] In this embodiment, when the first driving member 8 slides to the first position, the locking rod 13 extends from the mounting base 26 through the third through hole 43. When the vehicle is charging, the locking rod 13 can lock and cooperate with the electronic locking mechanism on the charging gun. The cooperation between the electronic locking mechanism and the locking rod 13 is prior art and will not be described in detail here.

[0075] In one embodiment, the charging adapter further includes a micro switch 10, which is installed in the mounting groove 14 and faces the side where the first driving member 8 is located. The bottom wall of the mounting groove 14 is provided with a fourth through hole 11. The micro switch 10 is electrically connected to the circuit board 34 inside the housing 1 through a cable passing through the fourth through hole 11. When the micro switch 10 is open, the circuit between the input terminal 36 and the output terminal 37 is connected. When the micro switch 10 is closed, the circuit between the input terminal 36 and the output terminal 37 is disconnected.

[0076] In this embodiment, the micro switch 10 is a normally open switch. When the first driving member 8 slides to the first position, the first driving member 8 disengages from the micro switch 10, thereby opening the micro switch 10. When the first driving member 8 slides to the second position, the first driving member 8 presses the micro switch 10, thereby closing the micro switch 10.

[0077] In this embodiment, the bottom wall of the mounting groove 14 is also provided with a first locking groove 41 and a second locking groove 42 spaced apart. The first locking groove 41 is located below the first driving member 8 when it is in the first position, and the second locking groove 42 is located below the first driving member 8 when it is in the second position.

[0078] The bottom of the first driving member 8 is provided with a groove, in which a ball 44 deforms in the vertical direction. The second elastic member 21 can drive the locking pin 23 to move downward. When the first driving member 8 is in the first position, the ball 44 is engaged in the first locking groove 41. When the first driving member 8 is in the second position, the ball 44 is engaged in the second locking groove 42. Without external force, the ball 44 is engaged in the first locking groove 41 or the second locking groove 42 to prevent the first driving member 8 from shaking. When the operator pushes the second driving member 12 to drive the first driving member 8 to slide, the ball 44 can move with the first driving member 8, thereby switching between the first locking groove 41 and the second locking groove 42.

[0079] 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.

[0080] The charging adapter provided in this embodiment of the invention works on the following principle:

[0081] When the vehicle is charging, the pusher 24 is pushed towards the plug-in part 4, causing the first drive member 8 to move to the second position, thus unlocking the locking member 9. Then, the charging gun is plugged into the first side 2 of the charging adapter, so that the first signal input terminal 38 is plugged into the charging gun signal terminal and the input terminal 36 is plugged into the charging gun current terminal. Then, the plug-in part 4 of the charging adapter is plugged into the charging hole of the charging socket, so that the output terminal 37 is plugged into the charging gun current terminal and the first signal output terminal 39 is plugged into the charging gun signal terminal. Then, the pusher 24 is pushed away from the plug-in part, causing the first drive member 8 to move to the first position, so that the latch on the locking part 18 is locked into the locking hole of the charging socket. At the same time, the locking rod 13 extends out of the mounting base 26 and locks with the electronic lock mechanism of the charging gun. The first drive member 8 moves away from the micro switch 10, thereby opening the micro switch 10 and connecting the circuit between the charging gun and the charging socket.

[0082] After the vehicle is fully charged, push the pusher 24 toward the plug-in part 4 to move the first drive member 8 to the second position, thereby unlocking the locking member 9 and causing the hook 19 of the latching part 18 to disengage from the latching hole of the charging socket. The locking rod 13 retracts into the mounting base 26. At the same time, the first drive member 8 presses the micro switch to close the micro switch 10, thereby disconnecting the circuit between the charging gun and the charging socket. Then, unplug the charging adapter from the charging socket and then unplug the charging gun from the charging adapter.

[0083] According to the charging adapter provided in this embodiment of the present utility model, the plug part 4 is used to plug into the charging hole of the charging socket so that the output terminal 37 is plugged into the socket current terminal. The locking component can lock the plug part 4 in the charging hole in the locked state. Only when the locking component is switched to the unlocked state can the plug part 4 be pulled out from the charging hole to prevent plugging and unplugging while the power is on.
