Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0031] A car charging adapter is a device used to connect different types of charging interfaces. It allows cars with specific charging interfaces to be adapted to charging piles and charging stations with different charging standards or charging protocols for charging. For example, it can adapt to charging standards of different car manufacturers and different countries and regions.

[0032] In the related art, the charging gun or adapter can be plugged in and out at will during the charging process using a car charging adapter, which may cause the safety problem of "arcing", that is, the arc discharge produces high temperature and high energy, causing damage to the charging interface and even causing a fire. Moreover, the temperature of the car charging adapter in the related art will rise sharply when charging for a long time or overcharging, and there will be various safety hazards if charging is continued under high temperature conditions. All the above-mentioned defects are not conducive to the safe charging of the car.

[0033] Reference Figure 1 , shows a schematic diagram of the structure of a charging adapter for a car according to an embodiment of the utility model, the charging adapter comprising:

[0034] Subject 1;

[0035] In this embodiment, the main body 1 is the main body of the charging adapter, which is used to fix the terminal assembly 4 and transmit electrical energy during the charging process of the car.

[0036] A first shell 2, disposed at one end of the main body 1;

[0037] The second shell 3 is arranged at the other end of the main body 1 and is installed and matched with the first shell 2;

[0038] In this embodiment, the first housing 2 is a housing adapted for inserting a charging gun, and the second housing 3 is a housing adapted for inserting into a charging port of a car. The first housing 2 and the second housing 3 are installed and matched with each other to form the housing of the entire charging adapter. The assembly diagram is shown in FIG. Figure 2 shown.

[0039] In some embodiments of the present invention, the second housing 3 is provided with a second slot structure 31 , and the second slot structure 31 matches the second locking structure of the charging interface of the vehicle.

[0040] In this embodiment, the second slot structure 31 matches the second locking structure of the car's charging port, so that the charging adapter is locked from one end of the second shell 3 when the adapter is inserted into the car's charging port, thereby preventing the charging adapter from detaching from the car's charging port during charging.

[0041] In actual applications, the first shell 2 can be a shell for inserting a charging gun that is adapted to adopt the US charging interface standard (such as the SAE J1772 standard, also known as the type 1 standard), and the second shell can be a shell for adapting to the automotive charging interface that adopts the European charging interface standard (such as the type 2 standard specified in the IEC 62196 standard).

[0042] The terminal assembly 4 is arranged between the main body 1 and the second shell 3, and the end of the terminal assembly 4 close to the main body 1 is provided with a first terminal array matched with the charging interface of the charging gun, and the end of the terminal assembly 4 close to the second shell 3 is provided with a second terminal array matched with the charging interface of the car; wherein a temperature control switch is provided on the current path between the first terminal array and the second terminal array;

[0043] In this embodiment, a first terminal array that is matched with the charging interface of the charging gun is provided at one end of the terminal assembly 4 close to the main body 1, and a second terminal array that is matched with the charging interface of the car is provided at one end close to the second shell 3, so as to realize the adaptation and conversion of charging guns and charging interfaces of cars using different charging standards during the charging process.

[0044] In actual applications, the terminal assembly 4 can be composed of multiple terminals, and each terminal has its corresponding function, such as a DC positive terminal and a DC negative terminal responsible for transmitting electric energy, a control wire terminal responsible for transmitting communication signals between the charging pile and the car, and a ground terminal to ensure safe grounding during charging.

[0045] In this embodiment, a temperature control switch is provided on the current path between the first terminal array and the second terminal array to disconnect the current path when the charging temperature is too high, thereby stopping the charging gun from charging the car and avoiding accidents such as fire.

[0046] In practical applications, a temperature control switch may be provided on one or more terminals in the first terminal array and / or the second terminal array, and the disconnection threshold temperature of the temperature control switch may be set to 95±5°C, and the recovery threshold temperature may be set to 75±15°C.

[0047] As an example, Figure 3 As shown, the temperature control switch is set on the DC terminal of the first terminal array and connected in series in the circuit. When the temperature of the DC terminal is detected to exceed 95°C, the contact of the temperature control switch automatically pops open, and the resistance value of the PE line (ground line) and PP line (power signal line) in the circuit increases to infinity. At this time, the circuit structure is as follows: Figure 4 As shown, the current path between the first terminal array and the second terminal array is equivalent to being applied with a resistor with a larger resistance value, that is, the current path is disconnected and charging stops; when it is detected that the temperature of the terminal returns to 75°C, the contacts of the temperature control switch automatically close, and the car enters the charging process again and charging resumes.

[0048] In some embodiments of the utility model, it is characterized in that the temperature-controlled switch is arranged at the DC positive pole of the first terminal array and / or the DC negative pole of the first terminal array; or, the temperature-controlled switch is arranged at the DC positive pole of the second terminal array and / or the DC negative pole of the second terminal array.

[0049] In this example, the temperature of the DC terminal can reflect the charging temperature, so the temperature control switch can be set on the DC positive pole and / or DC negative pole of the first terminal array and / or the second terminal array, so as to promptly disconnect the current path between the first terminal array and the second terminal array when the temperature of any terminal is too high.

[0050] In some embodiments of the present invention, it is characterized in that the first terminal array and the second terminal array are terminal arrays with different arrangement orders corresponding to different charging standards.

[0051] In this embodiment, the first terminal array and the second terminal array are terminal arrays with different arrangement orders corresponding to different charging standards, so as to achieve adaptation and conversion of different charging standards.

[0052] In actual applications, the first terminal array can be the terminal arrangement order of the charging interface corresponding to the US SAE J1772 standard, that is, from left to right, the ground terminal, the neutral terminal, the phase terminal, and the control wire terminal; the second terminal array can be the terminal arrangement order of the charging interface corresponding to the European type 2 standard, that is, from left to right, the ground terminal, the neutral terminal, the phase terminal, the control wire terminal, and the auxiliary wire terminal.

[0053] An electronic lock 5 , one end of which is fixed to the first shell 2 , and the other end of which is fixed to the second shell 3 .

[0054] In this embodiment, the function of the electronic lock 5 is to lock the charging gun when the charging gun is inserted into the charging adapter to prevent the charging gun from being plugged in or out at will.

[0055] In some embodiments of the utility model, the electronic lock 5 includes a micro switch and a first locking structure 51, the micro switch is connected to the first locking structure 51, the first locking structure 51 is matched with the first slot structure of the charging gun and with the opening structure of the first shell 2.

[0056] In a specific implementation, when the charging gun is inserted into the charging adapter, the microswitch of the electronic lock 5 changes from an open state to a closed state, the first locking structure 51 pops out and extends out of the first shell 2 through the opening structure of the first shell 2, and is connected to the first slot structure of the charging gun, thereby locking the charging gun.

[0057] In some embodiments of the present invention, the charging adapter further includes:

[0058] A battery 6 , wherein the battery 6 is electrically connected to the electronic lock 5 .

[0059] In this embodiment, the battery 6 is used to provide power to the driving device of the electronic lock. In practical applications, the battery 6 can also be supplemented with power through an external power adapter.

[0060] In some embodiments of the present invention, the charging adapter further includes:

[0061] A control board 7 , wherein the control board 7 is electrically connected to the electronic lock 5 and the battery 6 .

[0062] In a specific implementation, the control board 7 can be used to control the opening or closing of the micro switch in the electronic lock 5 to control the locking or unlocking of the charging gun; the control board 7 can also be used to control the battery 6 to replenish the charging adapter according to the voltage value of the charging pile during the charging process to prevent the charging adapter from feeding power.

[0063] In some embodiments of the present invention, the control board 7 includes a charging gun signal receiving module and an electronic lock control module.

[0064] In a specific implementation, when the charging gun is inserted into the charging adapter, the control board 7 receives the charging gun insertion signal through the charging gun signal receiving module, and then controls the closing action of the micro switch of the electronic lock 5 through the electronic lock control module, so that the first locking structure 51 pops up to lock the charging gun, and then the electronic lock 5 feeds back the signal of the action completion to the control board 7. At this time, one end of the second housing 3 of the charging adapter has also been locked through the second card slot structure 31 and the second locking structure of the vehicle charging interface, and both ends of the charging adapter are locked, and the charging gun and the adapter cannot be pulled out.

[0065] In practical applications, since both ends of the charging adapter are locked and a temperature control switch is provided in the current path between the first terminal array and the second terminal array, the safety of car charging is guaranteed. A larger charging current (for example, 250A) can be used to increase the charging power and shorten the charging time.

[0066] In some embodiments of the present invention, the battery 6 is a lithium battery, and the control board 7 is an assembled printed circuit board.

[0067] In practical applications, the battery 6 may be a 5V lithium battery; the control board 7 may be a printed circuit board assembly (PCBA), which has the advantages of being small and lightweight.

[0068] In some embodiments of the present invention, a power supply system for a car is also provided, the power supply system comprising a charging gun, a charging interface of the car and the charging adapter as described above.

[0069] The embodiments of the utility model have the following advantages: by arranging a temperature control switch on the current path of the first terminal array and the second terminal array, the connection between the charging gun and the car can be disconnected when the charging temperature of the car is too high, thereby avoiding the safety hazard of fire, and by arranging an electronic lock between the first shell and the second shell, the charging gun can be prevented from being plugged in and out at will during the charging process, thereby effectively ensuring the safety of the charging process using the car charging adapter.
