the first interface 140, the second interface 150, and the third interface 160 are all communicatively connected to the control module 120, and the control module 120 is configured to obtain power supply information of the first interface 140, master device information of the second interface 150, and slave device 40 information of the third interface 160; the second interface 150 is connected to the third interface 160, and the control module 120 is configured to determine a transmission speed of data input by the second interface 150 according to the master device information and the slave device 40 information, and control the second interface 150 to output the data to the third interface 160 according to the transmission speed;
The first interface 140, the second interface 150 and the third interface 160 are all connected with the gating module 130, the gating module 130 is connected with the power module 110, and the power module 110 and the gating module 130 are both connected with the control module 120; the control module 120 is configured to determine a power supply mode according to the power supply information, the master device information, and the slave device information, and control the gating module 130 to gate the connection between the first interface 140, the second interface 150, the third interface 160, and the power module 110 according to the power supply mode, so as to supply power to the first interface 140, the second interface 150, and the third interface 160.
The control module 120 may configure the communication channels of the first interface 140, the second interface 150, and the third interface 160, so that the control module 120 performs information interaction with the first interface 140, the second interface 150, and the third interface 160, and manages data transmission and power supply of the adapter 10 according to information input by each interface.
Specifically, the second interface 150 may be connected to the master device 30, so that the control module 120 obtains master device information input by the second interface 150. The third interface 160 may be connected to the slave device 40 such that the control module 120 obtains slave device information input by the third interface 160. The master information refers to information transmitted by the master device 30 to the control module 120 through the second interface 150, for example, the master information includes master connection information, transmission data, power supply information, transmission mode, and the like. The slave device information refers to information transmitted from the slave device 40 to the control module 120 through the third interface 160, and for example, the slave device information includes information such as a slave device 40 connection signal and a charging signal. Thus, the control module 120 may determine a transmission speed of data input by the second interface 150 according to the master device information and the slave device information, control the second interface 150 to output the data to the third interface 160 according to the transmission speed, and control the master device 30 to supply power to the slave device 40.
The first interface 140 may be connected to the power adapter 20, so that the control module 120 obtains power supply information input by the first interface 140 to individually power the master device 30 connected to the second interface 150, individually power the slave device 40 connected to the third interface 160, or simultaneously power the master device 30 connected to the second interface 150 and the slave device 40 connected to the third interface 160.
The gating module 130 is a conductive loop selector of the adapter 10, and the control module 120 may control the gating module 130 to conduct the first interface 140 with the second interface 150, conduct the first interface 140 with the third interface 160, conduct the first interface 140 with the power module 110, conduct the second interface 150 with the power module 110, conduct the third interface 160 with the power module 110, and conduct the second interface 150 with the third interface 160. The power module 110 may convert the power input thereto into a suitable voltage to be provided to the control module 120, the first interface 140, and the second interface 150.
The operation of the adaptor 10 will be described based on the above connection relation:
When the second interface 150 is connected to the master device 30 and the third interface 160 is connected to the slave device 40, the master device 30 acts as a power supply device to supply power to the adapter 10 and the slave device 40, so that the master device 30 can transmit data to the slave device 40 through the adapter 10. Specifically, after the control module 120 obtains the master device information and the slave device information, the control module 120 controls the gating module 130 to conduct the second interface 150 with the power module 110, so that the master device 30 supplies power to the power module 110. The power module 110 may convert the input power into voltage and then supply power to the control module 120. At the same time, the control module 120 controls the gating module 130 to turn on the second interface 150 and the third interface 160 so that the master device 30 supplies power to the slave device 40. If the control module 120 determines that the data output by the host device 30 is high-speed video data according to the host device information, it can determine that the transmission speed of the data input by the second interface 150 is high-speed transmission, and can control the second interface 150 to output the data to the third interface 160 at high speed. If the control module 120 determines that the data output by the host device 30 is low-speed data according to the host device information, it may determine that the transmission speed of the data input by the second interface 150 is low-speed transmission, and may control the second interface 150 to output the data to the third interface 160 at a low speed.
When the first interface 140 is connected to the power adapter 20, the second interface 150 is connected to the master device 30, and the third interface 160 is connected to the slave device 40, the power adapter 20 may supply power to the adapter 10, the master device 30, and the slave device 40 as power supply devices, so that the power adapter 20 may supply power to the master device 30 or the slave device 40 alone or supply power to both the master device 30 and the slave device 40 simultaneously. Specifically, after the control module 120 obtains the power supply information, the master device information, and the slave device information, the control module 120 controls the gating module 130 to conduct the first interface 140 with the power module 110, so that the power adapter 20 supplies power to the power module 110. The power module 110 performs voltage conversion on the input electric energy and then supplies power to the control module 120. If the control module 120 determines that the voltage requested by the master device 30 is greater than or equal to the initial voltage requested by the control module 120 to the power adapter 20 through the first interface 140 according to the power supply information, the master device information and the slave device information, the control module 120 determines that the power supply mode is the first power supply mode, that is, the control gating module 130 turns on the first interface 140 and the second interface 150, so that the power adapter 20 supplies power to the master device 30. If the control module 120 determines that the voltage requested by the master device 30 is less than the initial voltage requested by the control module 120 to the power adapter 20 according to the power supply information, the master device information and the slave device information, the control module 120 determines that the power supply mode is the second power supply mode, that is, the control gating module 130 conducts the power supply module 110 with the second interface 150, so that the power supply module 110 supplies power to the master device 30. At the same time, the control module 120 may further control the gating module 130 to conduct the power module 110 to the third interface 160, so that the power module 110 supplies power to the slave device 40. If the control module 120 determines that the data output by the host device 30 is high-speed video data according to the host device information, it can determine that the transmission speed of the data input by the second interface 150 is high-speed transmission, and can control the second interface 150 to output the data to the third interface 160 at high speed. If the control module 120 determines that the data output by the host device 30 is low-speed data according to the host device information, it may determine that the transmission speed of the data input by the second interface 150 is low-speed transmission, and may control the second interface 150 to output the data to the third interface 160 at a low speed.
The control module 120 of the adaptor 10 according to the present utility model may determine the transmission speed of the data input by the second interface 150 according to the master device information and the slave device information, and control the second interface 150 to output the data to the third interface 160 according to the transmission speed. The control module 120 may also determine a power supply mode according to the power supply information, the master device information, and the slave device information, and control the gating module 130 to gate the connection between the first interface 140, the second interface 150, the third interface 160, and the power module 110 according to the power supply mode, so as to supply power to the first interface 140, the second interface 150, or the third interface 160. In this way, the adapter 10 designed by the power module 110, the control module 120, the gating module 130, the first interface 140, the second interface 150 and the third interface 160 can charge the connection device while transmitting data to the connection device.
On the basis of the above embodiment, fig. 2 is a schematic structural diagram of another adaptor according to the embodiment of the present utility model, as shown in fig. 2, the gating module 130 includes a first switch 131, a second switch 132, a third switch 133, a fourth switch 134 and a fifth switch 135; the first interface 140 is connected to the first switch 131, the second interface 150 is connected to the second switch 132 and the third switch 133, the third interface 160 is connected to the fourth switch 134 and the fifth switch 135, the third switch 133, the first switch 131, the fifth switch 135, and the power module 110, and the second switch 132 and the fourth switch 134 are connected to the power module 110, respectively.
The operation of the adaptor 10 will be further described according to the above connection relation:
When the second interface 150 is connected to the master device 30 and the third interface 160 is connected to the slave device 40, the master device 30 acts as a power supply device to supply power to the adapter 10 and the slave device 40, so that the master device 30 can transmit data to the slave device 40 through the adapter 10. Specifically, after the control module 120 obtains the master device information and the slave device information, the control module 120 controls the third switch 133 to close to conduct the second interface 150 with the power module 110, so that the master device 30 supplies power to the power module 110. The power module 110 performs voltage conversion on the input electric energy and then supplies power to the control module 120. The control module 120 controls the fifth switch 135 to close to turn on the second interface 150 and the third interface 160 to enable the master device 30 to power the slave device 40. If the control module 120 determines that the data output by the host device 30 is high-speed video data according to the host device information, it can determine that the transmission speed of the data input by the second interface 150 is high-speed transmission, and can control the second interface 150 to output the data to the third interface 160 at high speed. If the control module 120 determines that the data output by the host device 30 is low-speed data according to the host device information, it may determine that the transmission speed of the data input by the second interface 150 is low-speed transmission, and may control the second interface 150 to output the data to the third interface 160 at a low speed.
When the first interface 140 is connected to the power adapter 20, the second interface 150 is connected to the master device 30, and the third interface 160 is connected to the slave device 40, the power adapter 20 may supply power to the adapter 10, the master device 30, and the slave device 40 as power supply devices, so that the power adapter 20 may supply power to the master device 30 or the slave device 40 alone or supply power to both the master device 30 and the slave device 40 simultaneously. Specifically, after the control module 120 obtains the power supply information, the master device information, and the slave device information, the first switch 131 may be controlled to be closed to conduct the first interface 140 with the power module 110, so that the power adapter 20 supplies power to the power module 110. The power module 110 performs voltage conversion on the input electric energy and then supplies power to the control module 120. If the control module 120 determines that the voltage requested by the master device 30 is greater than or equal to the initial voltage requested by the control module 120 to the power adapter 20 through the first interface 140 according to the power supply information, the master device information and the slave device information, the control module 120 determines that the power supply mode is the first power supply mode, that is, controls the third switch 133 to be closed to conduct the first interface 140 and the second interface 150, so that the power adapter 20 supplies power to the master device 30. If the control module 120 determines that the voltage requested by the master device 30 is less than the initial voltage requested by the control module 120 to the power adapter 20 according to the power supply information, the master device information and the slave device information, the control module 120 determines that the power supply mode is the second power supply mode, that is, controls the second switch 132 to be closed to conduct the power supply module 110 and the second interface 150, so that the power supply module 110 supplies power to the master device 30. At the same time, the control module 120 may further control the fourth switch 134 to be turned on to connect the power module 110 to the third interface 160, so that the power module 110 supplies power to the slave device 40. If the control module 120 determines that the data output by the host device 30 is high-speed video data according to the host device information, it can determine that the transmission speed of the data input by the second interface 150 is high-speed transmission, and can control the second interface 150 to output the data to the third interface 160 at high speed. If the control module 120 determines that the data output by the host device 30 is low-speed data according to the host device information, it may determine that the transmission speed of the data input by the second interface 150 is low-speed transmission, and may control the second interface 150 to output the data to the third interface 160 at a low speed.
