Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6 The utility model describes the above technical solution in detail through the following embodiments:

[0027] A charging interface protection device comprises: a car charging interface 1; a plug connector 2 is embedded in the interior of the car charging interface 1, a charging gun 3 is fixedly connected to the end of the plug connector 2 away from the car charging interface 1, three first conductive blocks 4 are evenly and fixedly connected to the car charging interface 1 near the plug connector 2, and a matching second conductive block 5 is fixedly connected to the charging gun 3 near the first conductive block 4; a movable sealing mechanism 6 is arranged between the first conductive block 4 and the second conductive block 5; a snap-fit ​​mechanism 7 is arranged inside the plug connector 2 to prevent the plug connector 2 and the car charging interface 1 from loosening, and a user inserts the plug connector 2 on the charging gun 3 into the interior of the car charging interface 1 through the snap-fit ​​mechanism 7, and the sealing mechanism 6 automatically connects the first conductive block 4 with the second conductive block 5 during the insertion, so that the charging gun 3 can charge the new energy vehicle through the car charging interface 1.

[0028] like Figure 1 and Figure 3As shown, the sealing mechanism 6 includes: a conductive copper sheet 8 is arranged between the first conductive block 4 and the second conductive block 5, and the conductive copper sheets 8 are fixed inside the movable plate 9, the movable plate 9 is slidably connected with the plug connector 2, a sealing plate 10 is arranged at the bottom of the movable plate 9, the sealing plate 10 is fixedly connected with the plug connector 2, and a matching cross groove 11 is opened near the conductive copper sheet 8 on the sealing plate 10; a first spring 12 is arranged between the movable plate 9 and the charging gun 3, and both ends of the first spring 12 are sleeved with limiting rings 13, and the two limiting rings 13 are respectively fixedly connected with the movable plate 9 and the charging gun 3, and the plug connector 2 is inserted into the interior of the vehicle charging interface 1. The first conductive block 4 inside the car charging interface 1 pushes the conductive copper sheet 8, and the conductive copper sheet 8 slides inside the plug connector 2 through the cooperation of the movable plate 9, so that the top of the conductive copper sheet 8 contacts the second conductive block 5, and then the charging gun 3 charges the new energy vehicle through the second conductive block 5, the conductive copper sheet 8 and the first conductive block 4. When separated, the first spring 12 pushes the movable plate 9 to move downward. While the movable plate 9 moves, it drives the conductive copper sheet 8, so that the conductive copper sheet 8 moves to the cross groove 11 inside the sealing plate 10, and the plug connector 2 is sealed, which can effectively prevent people from accidentally touching the charging gun 3 and getting an electric shock.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the locking mechanism 7 includes: a buckle 14 is provided inside the plug connector 2, and a matching slot 15 is provided near the buckle 14 at the vehicle charging interface 1, and a connecting plate 16 is fixedly connected to one side of the buckle 14, and the end of the connecting plate 16 away from the buckle 14 penetrates the plug connector 2 and the charging gun 3 and extends to the inside of the charging gun 3, and a pressing block 17 is fixedly connected to one side of the connecting plate 16 located inside the charging gun 3; the end of the pressing block 17 away from the connecting plate 16 penetrates the charging gun 3 and extends to the rubber pad 18, and the rubber pad 18 is fixedly connected to the pressing block 17; a control connection is provided on the side of the connecting plate 16 away from the pressing block 17 The elastic mechanism 19 of the plate 16 is used to reset the plug. When the user inserts the plug connector 2 into the car charging interface 1, he presses the pressing block 17. The pressing block 17 drives the connecting plate 16. The connecting plate 16 drives the buckle 14, so that the buckle 14 moves to the inside of the plug connector 2. Then the plug connector 2 is inserted into the car charging interface 1. Finally, the pressing block 17 is released. The elastic mechanism 19 pushes the connecting plate 16 to reset. The connecting plate 16 drives the buckle 14, so that the buckle 14 enters the card slot 15 inside the car charging interface 1, thereby improving the stability of the charging gun 3 when connected to the car charging interface 1 and avoiding looseness.

[0030] like Figure 2As shown, the elastic mechanism 19 includes: four limit rods 20 are evenly fixedly connected to the side of the connecting plate 16 away from the pressing block 17, the outer surface of the limit rod 20 is sleeved with a sleeve 21, and the end of the sleeve 21 away from the limit rod 20 is fixedly connected to the charging gun 3; the outer side of the sleeve 21 and the limit rod 20 is sleeved with a second spring 22, when the user releases the pressing block 17, the second spring 22 generates elastic recovery, and then pushes the connecting plate 16, so that the connecting plate 16 is reset while extending and retracting inside the sleeve 21 through the limit rod 20.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, the car charging interface 1 includes a panel 23, a protective cover 24, a base 25, an air inlet 26, an air outlet 27 and a heat dissipation cavity 28. The top of the panel 23 is hingedly connected to the protective cover 24, and the bottom of the panel 23 is fixedly connected to the base 25. The base 25 has a heat dissipation cavity 28 inside. The panel 23 has an air inlet 26 and an air outlet 27 inside. The air inlet 26 and the air outlet 27 are both inclined. The user can close the protective cover 24 to protect the car charging interface 1 when not charging to prevent rain or dust from entering the interior of the car charging interface 1.

[0032] like Figure 1 and Figure 6 As shown, a micro motor 29 is provided inside the heat dissipation cavity 28, and a fan blade 30 is fixedly connected to the output end of the micro motor 29. The micro motor 29 is fixedly connected to the base 25. The micro motor 29 is started, and the output end of the micro motor 29 drives the fan blade 30 to rotate. When the fan blade 30 rotates, the hot air inside the heat dissipation cavity 28 is blown out through the exhaust port 27. Since the hot air inside the heat dissipation cavity 28 generates negative pressure inside while being blown out, the outside air is sucked into the heat dissipation cavity 28 through the air inlet 26, thereby achieving the purpose of air circulation and avoiding the generation of a high temperature at the joint between the charging gun 3 and the vehicle charging interface 1 during charging.

[0033] like Figure 3 As shown, a sealing ring 31 is provided on the outer surface of the plug connector 2, and the sealing ring 31 is fixedly connected to the charging gun 3. A matching sealing groove 32 is provided near the sealing ring 31 at the vehicle charging interface 1, and a sealing rubber pad 33 is fixedly connected inside the sealing groove 32, which improves the sealing performance and can effectively prevent the short circuit caused by the entry of rainwater during charging.

[0034] Working principle: When the user inserts the plug connector 2 into the car charging interface 1, he presses the pressing block 17, and the pressing block 17 drives the connecting plate 16, and the connecting plate 16 drives the buckle 14, so that the buckle 14 moves to the inside of the plug connector 2, and then the plug connector 2 is inserted into the inside of the car charging interface 1, and finally the pressing block 17 is released. When the user releases the pressing block 17, the second spring 22 produces elastic recovery, thereby pushing the connecting plate 16, so that the connecting plate 16 is reset while being extended and retracted inside the sleeve 21 through the limiting rod 20. When the connecting plate 16 is reset, it drives the buckle 14, so that the buckle 14 enters the card slot 15 inside the car charging interface 1, thereby improving the stability of the connection between the charging gun 3 and the car charging interface 1 and avoiding the occurrence of looseness.

[0035] When the plug connector 2 is inserted into the vehicle charging interface 1, the micro motor 29 is started and the first conductive block 4 inside the vehicle charging interface 1 pushes the conductive copper sheet 8. The conductive copper sheet 8 slides inside the plug connector 2 through the cooperation of the moving plate 9, so that the top of the conductive copper sheet 8 contacts the second conductive block 5, and then the charging gun 3 charges the new energy vehicle through the second conductive block 5, the conductive copper sheet 8 and the first conductive block 4. When separated, the first spring 12 pushes the moving plate 9 to move downward, and the moving plate 9 drives the conductive copper sheet 8 while moving, so that the conductive copper sheet 8 moves to the sealing The plug connector 2 is sealed inside the cross groove 11 inside the plate 10, which can effectively prevent people from accidentally touching the charging gun 3 and causing electric shock. The output end of the micro motor 29 drives the fan blade 30 to rotate. While the fan blade 30 rotates, the hot air inside the heat dissipation cavity 28 is blown out from the exhaust port 27. Since the hot air inside the heat dissipation cavity 28 generates negative pressure inside while being blown out, the outside air is sucked into the heat dissipation cavity 28 through the air inlet 26, thereby achieving the purpose of air circulation and avoiding the generation of a high temperature at the joint between the charging gun 3 and the vehicle charging interface 1 during charging.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
