[0014] Figure 2 FIG. 4 is a block diagram of a port replicator according to some other embodiments of the present invention. DETAILED DESCRIPTION
[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0016] The port replicator according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.
[0017] Figure 1 FIG. 4 is a block diagram of a port replicator according to some embodiments of the present invention.
[0018] Reference Figure 1The port replicator 100 of the embodiment of the present application may include: a first connector 101, a main control chip 102 and a storage chip 103. The first connector 101 is configured to be connected to the external terminal device 200, the main control chip 102 is connected to the first connector 101, and the storage chip 103 is connected to the main control chip 102.
[0019] Specifically, the main control chip 102 is used to control the read and write operations and data transmission of the built-in USB flash drive of the port replicator 100, and enables the external terminal device 200 to identify the port replicator 100 as a "removable disk". The storage chip 103 is used to store data for a long time. The first connector 101 is configured to be connected to the external terminal device 200, and can be specifically a Type-C interface or a USB interface. The external terminal device 200 can be specifically an electronic device such as a computer, a mobile phone, an IPAD, etc. The main control chip 102 and the storage chip 103 are set in the port replicator 100, and the main control chip 102 is connected to the first connector 101, and the storage chip 103 is connected to the main control chip 102, so that the port replicator 100 can integrate the USB flash drive function.
[0020] Exemplarily, by inserting the first connector 101 of the port replicator 100 into the interface of an external terminal device 200 (such as a computer), the main control chip 102 can enable the external terminal device 200 to identify the port replicator 100 as a "removable disk". After the user issues an action instruction for data access, the data in the file can be saved in the storage chip 103 of the port replicator 100, or the data stored in the storage chip 103 can be transmitted to the external terminal device 200.
[0021] It should be noted that when a USB device is plugged into an external terminal device, the external terminal device recognizes that the USB device is a mass storage device that supports the Bulk-Only transmission protocol (block storage class protocol). At this time, it should be possible to transmit in Bulk-Only mode. In this mode, the data transmission between the USB and the device is realized through Bulk-In (block input) and Bulk-Out (block output). In addition, in this transmission mode, there are three types of data transmitted between the USB and the device, namely command block packets, command execution status packets and ordinary data packets.
[0022] The port replicator of the present application integrates the USB flash drive function on the basis of the traditional port replicator, so that the user does not need to carry an additional USB flash drive device, and can also move the data on the desktop of the electronic device into the port replicator to make the desktop of the electronic product tidier. In this way, the convenience, the user's work efficiency and the overall user experience are improved.
[0023] In some embodiments, reference Figure 2The port replicator 100 may further include: a video conversion chip 104 , the video conversion chip 104 is connected to the first connector 101 , the video conversion chip 104 is connected to the external display device 106 via the second connector 105 , and the video conversion chip 104 is connected to the external power supply 108 via the third connector 107 .
[0024] Specifically, the video conversion chip 104 is used to convert the video signal transmitted by the external terminal device 200 into an adapted video signal. For example, the adapted video signal can be a standard HDMI signal to ensure that video signals of different types, resolutions, and formats can be transmitted and displayed between external display devices. The second connector 105 can be specifically HDMI (High-Definition Multimedia Interface), which is used to connect an external display device 106 (such as a TV, a monitor, and a projector, etc.) and perform data transmission with the external terminal device 200, for example, transmitting a 4K@60Hz video signal, where 4K represents the video resolution and @60Hz represents the refresh rate. The third connector 107 indicates that the connected device only supports the power distribution function, but does not support other functions such as data transmission or video output. The external power supply 108 refers to the power supply supplied to the port replicator 100 itself, which can be an AC power adapter connected through a socket, or a DC power supply provided by a USB connection or other means, which is used to ensure that the port replicator 100 and the connected devices can operate normally and provide sufficient power supply when multiple high-power devices are connected.
[0025] Reference Figure 2 The video conversion chip 104 is connected to the third connector 107 through DFPCC1 and DFPCC2, and the third connector 107 is connected to the external power supply 108 to ensure that the device can be correctly configured for power supply.
[0026] Continue to refer to Figure 2 The video conversion chip 104 is connected to the first connector 101 through CC1 / CC2 (communication channel 1 / communication channel 2), SBU1 / 2 (Sideband Use channel 1 / Sideband Use channel 2), RRX0P / M signal and RRX1P / M signal, and the external terminal device 200 can output the video signal to the video conversion chip 104 through the first connector 101.
[0027] Exemplarily, the first connector 101 of the port replicator 100 is inserted into the interface of an external terminal device 200 (e.g., a computer). The external terminal device 200 transmits the video signal to the video conversion chip 104 through the first connector 101. The video conversion chip 104 converts the received video signal into an adapted video signal and transmits it to the external display device 106 (e.g., a projector) for display via the second connector 105.
[0028] In some embodiments, continue to refer to Figure 2 The port replicator 100 may further include an interface expansion chip 109, the interface expansion chip 109 is connected to the main control chip 102 and the video conversion chip 104 respectively, the main control chip 102 is connected to the first connector 101 through the interface expansion chip 109, and the interface expansion chip 109 is connected to the external device 111 through at least one fourth connector 110.
[0029] Specifically, the interface expansion chip 109 is used to expand the USB port to achieve connection and communication between different interface devices. The number of the fourth connector 110 is at least one. In the embodiment of the present application, two fourth connectors are used as an example for illustration. The external device 111 can be a USB flash drive, a hard disk, a mouse, etc.
[0030] For example, refer to Figure 2 , the first connector 101 is connected to the interface expansion chip 109 through the USBDP / M signal, the SSRX0P / M signal and the SSTX0P / M signal, and the data of the external terminal device 200 can be transmitted to the interface expansion chip 109 through the first connector 101. It should be noted that the external terminal device 200 only transmits one group of data, and the interface expansion chip 109 expands this one group of data into four groups, wherein the first group and the second group are respectively connected to the two fourth connectors to form two interfaces, and the user can insert the mouse port into the fourth connector 110 and use the mouse to control the external terminal device 200. The user can also insert the hard disk into another fourth connector (not shown) to transfer the data in the external terminal device 200 to the hard disk for storage. The third group is connected to the main control chip 102 and the storage chip 103 to form a built-in U disk of the port replicator 100. The user can store the data in the external terminal device 200 in the storage chip 103 of the port replicator 100, and conversely, the data in the storage chip 103 of the port replicator 100 can also be transferred to the external terminal device 200. The fourth group is connected to the network chip 112 to form a network interface.
[0031] It should be noted that the number of interface expansion chips is not unique. For example, when two interface expansion chips are set, the one group of data can be expanded into eight groups, which can be connected with multiple fourth connectors to form multiple USB interfaces to connect multiple external devices.
[0032] In some embodiments, when the first connector can be a Type-C interface, the main control chip 102 can be an IC1114 chip, the storage chip 103 can be a K9F080U0B_16MB chip (FLASH chip), the video conversion chip 104 can be an AG9411 chip, the third connector 107 can be a Type-C Charging only (only supports charging), the interface expansion chip 109 can specifically be a GL3510 chip, and the fourth connector 110 can be a USB-A interface.
[0033] In some embodiments, continue to refer to Figure 2 The port replicator 100 further includes a network chip 112 , which is connected to the interface expansion chip 109 , and is connected to an external routing device 114 via a fifth connector 113 .
[0034] Specifically, the network chip 112 may be a RTL8153B chip, which is used to provide a high-performance, stable wired network connection function for the external terminal device 200. The fifth connector 113 may be a RJ45 (Registered Jack-45, an 8-pin connector), which may be inserted into an external routing device 114, such as an Ethernet interface, to achieve network connection and communication between devices, and its data transmission rate may reach 1000M, which is not specifically limited here.
[0035] In some embodiments, continue to refer to Figure 2 The port replicator 100 may further include a power chip 115, which is connected to the main control chip 102, the storage chip 103, the video conversion chip 104, the interface expansion chip 109 and the network chip 112 respectively.
[0036] In some embodiments, continue to refer to Figure 2 The power chip 115 is also connected to the second connector 105 , the third connector 107 , the fourth connector 110 , and the fifth connector 113 , respectively.
[0037] Specifically, the power chip 115 can be an MP9247 chip, which is used to supply power to the main control chip 102, the storage chip 103, the video conversion chip 104, the interface expansion chip 109, the network chip 112, the second connector 105, the third connector 107, the fourth connector 110, and the fifth connector 113, for example, providing a 5V voltage, and no specific restrictions are made here.
[0038] In some embodiments, the port replicator 100 may further include a switch tube 116 , one end of which is connected to the first connector 101 , a second end of which is connected to the video conversion chip 104 and the third connector, and a third end of which is grounded.
[0039] Specifically, the switch tube 116 can be a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor), which is used to switch the power supply. When the third connector 107 is connected to the external power supply 108, the switch tube 116 switches the external power supply 108 to power the port replicator 100. When the third connector 107 is not connected to the external power supply 108, the switch tube 116 switches the external terminal device 200 to power the port replicator 100.
[0040] In summary, the port replicator of the present application integrates the USB flash drive function on the basis of the traditional port replicator, so that the user does not need to carry an additional USB flash drive device, and can also move the data on the desktop of the electronic device into the port replicator to make the desktop of the electronic product tidier. In this way, the convenience, user work efficiency and overall user experience are improved.
