Description

Technical Field

[0001] The utility model relates to the technical field of electric power, and relates to an AC-DC charging control device. Background Art

[0002] The existing energy storage architecture inside electric vehicles mainly uses batteries or supercapacitors, which store electrical energy in the form of direct current. A converter is required to convert the alternating current on the grid side into direct current that can be used by the battery. Therefore, charging management becomes an important technical point for electric vehicles.

[0003] Electric vehicles generally provide two charging ports: AC charging and DC charging. The AC charging pile provides alternating current and needs to cooperate with the AC-DC power conversion module in the car to complete the conversion of electrical energy to charge the battery. The DC charging pile places the AC-DC conversion link outside the car and can achieve a huge charging power by connecting multiple modules in parallel. Therefore, the so-called fast charging technology is based on DC charging piles. Due to the heat generated by the on-off conversion loss of current during the charging process, in order to ensure the safety of charging, its charging stations and other commercial facilities have temperature sensing functions for the charging heads, so as to perform corresponding alarm processing according to temperature standards during charging. However, when using home charging piles and portable charging devices, they are limited by functions. Ignoring temperature monitoring not only accelerates the aging of connectors and internal cables during charging, but also poses safety risks. Utility Model Content

[0020] See also Figure 1-3 , the embodiments of the utility model are further described;

[0021] An AC-DC charging control device comprises a housing 1 and a host 6, wherein the host 6 is arranged in the housing 1, a board seat 3 is arranged on one side of the housing 1, a pair of adapter sockets 4 are symmetrically arranged on the board seat 3, the two adapter sockets 4 are respectively of AC and DC interface specifications, and the adapter sockets 4 are electrically connected to the host 6;

[0022] A touch switch 11 is slidably provided on the inner side of the outer end of the adapter socket 4, and a wire bobbin 12 is slidably matched between the touch switch 11 and the adapter socket 4, a temperature resistance sensor is provided in the wire bobbin 12, and an electromagnetic handle ring 14 is sleeved on the outer side of the wire bobbin 12, and an outer ring protrudes from the outer side of the touch switch 11 to magnetically match the electromagnetic handle ring 14, and a compression spring ring 13 is provided at the connection between the adapter socket 4 and the touch switch 11;

[0023] A heat sink 5 embedded with the plate base 3 is provided between the two adapter sockets 4, a fan group 7 is provided in the heat sink 5, and a window is passed through the fan group 7 toward the outer end of the housing 1, a shunt pipe 8 is passed through the end of the fan group 7 toward the heat sink 5, and an air pipe 10 is passed through between the shunt pipe 8 and the wire bobbin 12;

[0024] The control device is bridged between the charging source and the device to be charged by two relatively arranged adapter sockets 4, and the plug cable and the socket are connected to the adapter socket 4 respectively. When the plug is inserted into the adapter socket 4, the charging source and the device to be charged are connected to the adapter socket 4 respectively. Figure 3 As shown, the plug overcomes the elasticity of the compression spring coil 13 to squeeze the touch switch 11 inward. After the external plug is fully connected with the adapter socket 4, the touch switch 11 will contact the touch end of the wire bobbin 12 to achieve a connection state, and on this basis, the electrical signal of the connection state is used to simultaneously energize the electromagnetic handle coil 14, and then the electromagnetic handle coil 14 is used to magnetically fix the touch switch 11 to continuously overcome the reaction force of the compression spring coil 13 to maintain the connection between the touch switch 11 and the wire bobbin 12. In this connection state, the temperature resistance sensor set in the wire bobbin 12 can sense and transmit The temperature of the end, which is preferably a PT1000 temperature resistance sensor, adjusts the temperature alarm threshold according to the charging standard, and when the temperature reaches the alarm threshold, the host 6 can cut off the power supply of the electromagnetic handle ring 14 to disconnect the connection between the electromagnetic handle ring 14 and the touch switch 11, and then use the reaction force of the compression spring ring 13 to cut off the connection between the touch switch 11 and the wire bobbin 12, and at the same time, a temperature alarm is issued. This physical charging cut-off method is used in conjunction with temperature control management to ensure the safety of the device when in use, and in conjunction with portable charging equipment, effectively broadens the use scenario;

[0025] At the same time, taking into account the current loss between the charging source and the charging end of the device bridge and the impact on the charging temperature, the device is internally provided with a heat dissipation component for the transmission end of the bobbin tube 12. When working, the braking of the fan group 7 is utilized to draw the airflow of the bobbin tube 12 along the shunt pipe 8 and the air pipe 10 and discharge it to the outside to achieve internal heat dissipation and meet the use scenario of long-term charging.

[0026] Furthermore, the housing 1 and the plate base 3 are aluminum alloy shells. Compared with the plastic shell structure, the aluminum alloy shell can ensure the structural strength while avoiding the influence of external electromagnetic interference on charging.

[0027] Furthermore, the inner wall of the wire bobbin tube 12 is filled with a woven aluminum foil layer, and a one-way airtight side-through pipe head 9 is provided between the wire bobbin tube 12 and the trachea 10. The woven aluminum foil layer for shielding provided in the wire bobbin tube 12 is used to isolate the wire bobbin tube 12 and the trachea 10 structure, and the side-through pipe head 9 provided between the trachea 10 and the wire bobbin tube 12 is used as the connecting end between the wire bobbin tube 12 and the trachea 10, thereby ensuring the shielding safety of the wire bobbin tube 12 transmission line while satisfying the realization of the heat dissipation component function.

[0028] On the basis of the above, if Figure 3 As shown, the cross-section of the touch switch 11 is T-shaped, and the outer edge of the touch switch 11 is fixed to the compression spring ring 13. By utilizing the distribution position and fixing method of the outer portion of the touch switch 11 and the compression spring ring 13, when the touch switch 11 slides axially, the distribution position of the compression spring ring 13 can be indirectly utilized to guide the axial sliding of the touch switch 11, so as to improve the sliding stability of the touch switch 11.

[0029] Furthermore, the maximum axial sliding distance of the touch switch 11 is smaller than the spacing between the touch switch 11 and the electromagnetic handle ring 14, and is relatively smaller than the margin of the spacing between the touch switch 11 and the electromagnetic handle ring 14. This can ensure that the sliding position of the touch switch 11 is maintained between the electromagnetic handle ring 14 and the bobbin tube 12, while ensuring the stability of the sliding structure. The remaining sliding distance margin serves as the activity margin when the compression spring ring 13 resets the touch switch 11, so as to ensure that the touch switch 11 can stably switch on and off.

[0030] On the basis of the above, the host 6 is embedded with an integrated display screen 2 at the outer end of the shell 1. As an extension of the host 6, the display screen 2 is used to display the temperature parameters and various data described above.
