[0034] like Figure 1-Figure 8 As shown, a charging pile interface protection device includes:
[0035] A front fixed seat 1 is provided with an active cavity 2 inside, and a limited sliding groove 3 is provided at the bottom of the inside. A guide block 4 is fixedly connected to the top of the active cavity 2, and a guide groove 5 is provided in the guide block 4. The guide groove 5 includes a left guide section 6, a left top guide section 7, a top limit section 8, a right top guide section 9, a right guide section 10 and a tail end guide section 11 which are sequentially connected end to end. The top of the grooves of the left top guide section 7 and the right top guide section 9 are concave toward the middle, the top limit section 8 is a "V"-shaped groove, the tail end guide section 11 is inclined downward toward the right guide section 10, and the bottom width of the right guide section 10 is greater than that of the left guide section 6;
[0036] The charging port 12 is slidably connected to the limiting slide groove 3. A mounting groove 13 is provided on the top of the charging port 12. A mounting block 14 is fixedly connected to the top of the mounting groove 13. A guide swing rod 15 is rotatably connected to the mounting block 14. A first torsion spring is fixedly connected between the guide swing rod 15 and the mounting block 14 so as to normally deflect the guide swing rod 15 to one side. The top of the guide swing rod 15 is slidably connected in the limiting slide groove 3. A hinge block 16 is fixedly connected to the rear end of the charging port 12.
[0037] A rear fixing seat 17 is fixedly connected to the rear portion of the front fixing seat 1, and a mounting cavity 18 is fixedly connected inside the rear fixing seat 17;
[0038] The trigger link 19 is rotatably connected to the rear fixed seat 17, and a second torsion spring is fixedly connected between the trigger link 19 and the rear fixed seat 17 for normally rotating the trigger link 19 upward. A pulling link 20 is hinged at the front end of the trigger link 19, and the front end of the pulling link 20 is hinged to the hinge block 16. By pulling the trigger link 19 upward, the charging port 12 is switched to the telescopic state in the front fixed seat 1.
[0039] In this embodiment, (the guide swing arm 15 is normally slightly tilted toward the side indicated by the arrow in the figure) when the vehicle needs to be charged, the trigger link 19 is pulled once to rotate the trigger link 19 downward. The rotation of the trigger link 19 will push the charging port 12 to slide forward by pulling the link 20, and simultaneously drive the top of the guide swing arm 15 to move in the guide groove 5. During this process, the guide swing arm 15 moves from the tail end guide section 11 to the right guide section 10 and the right top guide section 9. After the guide swing arm 15 is limited by the right top guide section 9, the trigger link 19 is released, so that the trigger link 19 is subjected to the rebound force of the second torsion spring, and the trigger link 19 is pulled by pulling the link 20. The charging port 12 retracts, and at the same time, the guide rocker arm 15 also moves from the right top guide section 9 to the top limit section 8. At this time, the charging port 12 is in an extended state, and at the same time, it is restricted by the "V"-shaped groove, and the charging port 12 will not retract when inserted into the vehicle for charging. After charging is completed, similarly, the trigger link 19 is pulled once to rotate the trigger link 19 downward, and the charging gun is unplugged. The rotation of the trigger link 19 will push the charging port 12 to slide forward by pulling the link 20. Under the pull of the rebound force of the second torsion spring, the guide rocker arm 15 moves from the top limit section 8 to the left guide section 6, and then to the tail guide section 11. At this time, the charging port 12 is retracted into the front fixing seat 1.
[0040] As an optional implementation, Figure 1 , 4 As shown in Figure 5, the left and right sides of the front fixed seat 1 are further provided with a protective mechanism 21, the protective mechanism 21 includes a rotating shaft 22 rotatably connected to the front fixed seat 1, each of the rotating shafts 22 is drivingly connected to a reeling motor 24 at the bottom, a waterproof cloth 25 is wound on the two rotating shafts 22, the front fixed seat 1 is symmetrically provided with two guide cloth grooves 26, the waterproof cloth 25 passes through the two guide cloth grooves 26 and is shielded at the front end of the front fixed seat 1, and a contact switch 27 is provided at the tail of the charging port 12, and the contact switch 27 is electrically connected to the reeling motor 24;
[0041] In this way, when the charging port 12 is in a retracted state, a contact switch 27 is set at the rear of the charging port 12 to make the main shafts of the two retracting motors 24 rotate forward briefly, so that the rotating shaft 22 rotates to retract the waterproof cloth 25, so that the waterproof cloth 25 closes the exposed gap of the front fixing seat 1. When the charging port 12 is in an extended state, the contact switch 27 set at the rear of the charging port 12 does not contact, and the main shafts of the two retracting motors 24 reverse briefly, so that the hole in the middle of the waterproof cloth 25 for the front end of the charging port 12 to pass through is exposed, so that the charging port 12 can be extended.
[0042] As an optional implementation, Figure 5 As shown, a hole is left in the middle of the waterproof cloth 25 for the front end of the charging port 12 to pass through;
[0043] In this way, the hole provides a way for the charging port 12 to extend out.
[0044] As an optional implementation, Figure 5-Figure 7 As shown, the charging port 12 is also fixedly connected to a connecting block 28, and a movable hook 29 is rotatably connected to the connecting block 28. A third torsion spring is fixedly connected between the movable hook 29 and the connecting block 28 to normally rotate the movable hook 29 downward. The movable hook 29 includes a trigger plate 30, and a blocking bar 31 is also fixedly connected to the front end of the bottom of the guide block 4;
[0045] In this way, the movable hook 29 is used to fix the connection between the charging gun and the vehicle charging port.
[0046] As an optional implementation, Figure 7 As shown, the trigger plate 30 contacts the blocking bar 31 only when the guide rocker 15 is located at the left top guide section 7 or the right top guide section 9;
[0047] In this way, when the charging personnel presses the trigger link 19 to make the guide rocker arm 15 located at the left top guide section 7 or the right top guide section 9 for plugging and unplugging, the charging gun can be successfully unplugged, and unplugging the charging gun will automatically shrink the charging port 12 and cover it with the waterproof cloth 25.
[0048] As an optional implementation, Figure 3 and Figure 4 As shown, the trigger link 19 is also fixedly connected with a first baffle 32 and a second baffle 33. When the charging port 12 is in a retracted state, the first baffle 32 blocks the gap between the trigger link 19 and the rear fixing seat 17. When the charging port 12 is in an extended state, the second baffle 33 blocks the gap between the trigger link 19 and the rear fixing seat 17.
[0049] In this way, when the charging port 12 is in the extended state or the retracted state, the second baffle 33 and the second baffle 33 can block the gap between the trigger link 19 and the rear fixing seat 17 .
[0050] As an optional implementation, Figure 3 and Figure 4 As shown, as an optional implementation, as Figure 3 As shown, the bottom of the charging port 12 is also fixedly connected to a wiring groove 34, the top of the installation cavity 18 is provided with a limiting groove 35, the bottom of the installation cavity 18 is fixedly connected to a limiting block 36, and the limiting block 36 is also provided with a wiring groove 37 tilted downward, and the wiring groove 37 is connected to the charging pile cable;
[0051] In this way, the limit block 36 is not only used to limit the rotation angle of the trigger link 19 and the pull link 20 , but also can limit the range of movement of the wire connected to the charging port 12 .
[0052] As an optional implementation, Figure 2 As shown, a lighting lamp 38 is arranged above the front end of the front fixing seat 1, a warning lamp 39 is arranged below the front end of the front fixing seat 1, and acoustic wave sensors 40 are also fixedly connected to both sides of the front fixing seat 1;
[0053] In this way, the lighting lamp 38 is used to charge the vehicle at night, making it convenient for the charging gun to be aimed at the charging port. The acoustic wave sensor 40 is used to sense the distance from the ground, so that when the charging gun is placed on the ground, the warning light 39 often flashes to remind passing vehicles to pay attention to the ground.
[0054] As an optional embodiment, the lighting lamp 38, the warning lamp 39 and the sound wave sensor 40 are electrically connected to the contact switch 27, the lighting lamp 38 is activated when the charging port 12 is in an extended state and the vehicle is not charged, and the warning lamp 39 and the sound wave sensor 40 are activated when the charging port 12 is in a retracted state;
[0055] In this way, the lighting lamp 38, the warning lamp 39 and the sound wave sensor 40 operate only when needed, thus saving power.
[0056] As an optional implementation, Figure 1 As shown, the rear fixing seat 17 is fixedly connected with a handle 41;
[0057] This makes it easier for the charging personnel to hold.
