[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 5As shown, a new energy vehicle charging adapter includes a base 1 and a fixed shell 2. The base 1 is fitted into the open end of the fixed shell 2. The base 1 is provided with an AC interface 101 and a DC interface 102. The AC interface 101 is provided with an AC terminal 3, and the DC interface 102 is provided with a DC terminal 4. A movable safety switch 5 is provided below the DC terminal 4. The safety switch 5 is used to control the connection status of the DC terminal 4. The DC interface 102 is also provided with an openable safety cover 6, so that the DC terminal 4 and the safety switch 5 are both placed between the safety cover 6 and the base 1. The fixed shell 2 has a car charging port 201 at its end. The car charging port 201 is provided with a charging rod 7 and a charging pin 8. The charging rod 7 is connected to the AC terminal 3 and the DC terminal 4 through a connecting block 9. The connecting block 9 is set inside the fixed shell 2. The charging rod 7 is made of copper. The fixed housing 2 is also provided with a PCB board 14, which is equipped with a temperature protection switch. The AC terminal 3, DC terminal 4, charging rod 7 and charging pin 8 are all electrically connected to the PCB board 14.
[0028] It should be noted that in this embodiment, the AC interface 101 is located above the DC interface 102. The AC interface 101 is provided with a terminal socket. One end of the AC terminal 3 passes through the base 1 and is inserted into the terminal socket of the AC interface 101, while the other end is inserted into the connecting block 9 and forms a contact connection with one end of the charging rod 7. The DC interface 102 is also provided with a terminal socket. One end of the DC terminal 4 passes through the base 1 and is inserted into the terminal socket of the DC interface 102, while the other end is inserted into the connecting block 9 and connected to the charging rod 7 through the connecting block 9. A switch socket is provided below the port 102, and the outer end of the safety switch 5 can be movably inserted into the switch socket; the car charging port 201 is provided with a connecting rod socket and a pin socket, one end of the charging connecting rod 7 is inserted into the connecting rod socket, and the other end is inserted into the connecting block 9, one end of the charging pin 8 is inserted into the pin socket, and the other end is inserted into the fixed shell 2; the PCB board 14 is provided with a temperature protection switch, when the temperature rises to the set protection temperature, the switch works to stop charging, and when the temperature drops to the normal start temperature, it will resume conduction and charging, thus effectively increasing the safety of this utility model.
[0029] like Figures 2 to 3As shown, a switch spring 10 is provided between the end of the safety switch 5 located inside the base 1 and the connecting block 9. One end of the switch spring 10 abuts against the end of the safety switch 5, and the other end abuts against the isolation block 11. The isolation block 11 is located between the switch spring 10 and the connecting block 9. The outer center of the safety cover 6 is provided with a protruding pull-out portion 601. The upper end of the safety cover 6 is provided with a safety cover limiting groove 602. The lower part of the safety cover 6 is provided with a safety cover mounting portion 603 that forms a rotatable connection with the base 1. The connecting block 9 is made of copper, and the outer surface of the copper block is covered with an insulating layer 901. The connecting block 9 is provided with a connecting rod socket and a terminal socket.
[0030] It should be noted that in this embodiment, the safety switch 5 is designed so that if the charging gun is not fully inserted into the DC interface 102 during charging, the safety switch 5 will not be activated, and the DC interface 102 will not be able to start charging. When the user needs to use the AC interface 101, the safety cover 6 needs to be placed on the DC interface 102. This serves two purposes: firstly, to cover the DC interface 102 and prevent the user from accidentally touching the DC interface 102 while using the AC interface 101, thus avoiding electric shock; secondly, if the safety cover 6 is not placed on the DC interface 102, the AC interface 101 cannot be activated for charging, further increasing the safety of this invention. The safety cover limiting groove 602 is designed so that when the user is using the AC interface 101 and the American standard AC charging gun is fully inserted into the AC interface 101, it will press against the safety cover limiting groove 602 of the safety cover 6, preventing the safety cover 6 from falling off.
[0031] like Figures 3 to 4 As shown, the upper part of the base 1 is provided with a charging gun slot 103, and a push rod 12 is slidably connected to the upper wall of the charging gun slot 103. The push rod 12 is Z-shaped, with its upper horizontal part being fitted into the upper part of the base 1 and located in the charging gun slot 103, and its lower horizontal part extending through the fixing shell 2 toward the car charging port 201. A push rod spring 13 is fitted onto the upper horizontal part of the push rod 12.
[0032] It should be noted that in this embodiment, the push rod 12 is designed so that when the present invention is inserted into the charging port of the car, the push rod 12 will be pushed out and press down on the hook of the American standard gun. At this time, the American standard gun hook cannot be dislodged from the groove due to the limitation of the push rod 12, which prevents the charging gun from falling off during the charging process and prevents children or people from pulling it out during the charging process. This can further increase the safety of the present invention.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
