The locking rod 212 can move along the length direction of the carrier 231 and has a first position and a second position relative to the carrier 231. The lock accessory 21 is in the first position relative to the carrier 231, and the host 1 and the expansion dock 2 are in a locked state.

[0047] When the main unit 1 is inserted into the expansion dock 2, the connector 22 of the expansion dock 2 is inserted into the connection interface 14 of the main unit 1, enabling electrical connection for signal transmission, power supply, and other functions. The connection interface 14 of the connector 22 is sized and functionally compatible. The connection between the main unit 1 and the expansion dock 2 is controlled by the locking rod 212 to ensure a secure connection. When the main unit 1 and the expansion dock 2 are combined, the locking rod 212 automatically locks. One end of the locking rod 212 is equipped with an unlocking switch, which, when activated, causes the locking accessory 21 to move between a first position and a second position. The locking accessory 21 also includes an elastic component, which can be a spring or a tension spring. The elastic component, connected to the locking rod 212, provides elastic restoring force. The locking accessory 21 is in the second position relative to the carrier 231, and the main unit 1 and the expansion dock 2 are in the unlocked state. To remove the main unit 1 from the expansion dock 2, the locking rod 212 must be manually unlocked first to disconnect the connector 22 from the connection interface 14, after which the main unit 1 can be separated. At this point, the host 1 can be separated from the docking station 2. The host 1 can be used independently, and it will be more convenient and efficient to use only the host 1 when connecting via wireless screen projection, Bluetooth connection, etc.

[0048] The connector 22 is fixedly connected with the bearing 231, the connector 22 is located in the accommodating space and is plugged with the connecting interface 14 of the host computer 1, the connector 22 is located on the same side of the bearing 231 as the locking accessory 21, the locking accessory 21 has two lock heads 211, the two lock heads 211 can synchronously move, so that the host computer 1 and the docking station 2 are in a locked state or an unlocked state, the connector 22 is located between the two lock heads 211 of the locking accessory 21, the stability of connection and locking is increased, the connector 22 does not affect the movement of the locking accessory 21, when in the locked state, the lock head 211 is clamped in the locking port 13, the host computer shell 12 is fixedly connected with the connecting portion 23, the connection state of the connector 22 and the connecting interface 14 is ensured, when in the unlocked state, the lock head 211 is located in the locking port 13 but does not clamp, the host computer shell 12 can be disassembled relative to the connecting portion 23, the connector 22 and the connecting interface 14 can also be separated at this time.

[0049] The first side of the bearing 231 is provided with an indication assembly 234 and a switch assembly 235, the first side of the bearing 231 is a side facing the user, so as to facilitate observation of the display state of the indication assembly 234, in order to keep the simplicity of the overall appearance and the convenience of operation, the user can conveniently turn on or off when connecting the equipment.

[0050] The indication assembly 234 includes at least one indicator, for example, one indicator, when the docking station 2 is connected to the power supply and normally starts, the indicator is bright, indicating that the docking station 2 is powered on and runs, the constant light indicates that the network physical connection is normal, the flicker indicates that there is data transmission in the network. If the indicator does not light, it may be that the network cable is not inserted well, the network interface is faulty or the network setting problem, for example, an LED indicator: a power lamp (green), a hard disk lamp (blue), a overheating lamp (red), different colors at least different states.

[0051] The indication component 234 can be provided with a power supply indication light to indicate the power supply state: usually in the form of a constant light to indicate that the docking station 2 has been powered on and the power supply is normal. If the power supply indication light is not on, the device will not work normally, and the power supply problem needs to be checked in time. The indication component 234 can be provided with a connection state indication light. When a USB device such as a U disk or a mobile hard disk is inserted into the USB interface of the docking station 2, the corresponding indication light will light up, indicating that the device is connected successfully. If the indication light is not on, it may be that the interface is not in good contact, the device is faulty or the docking station 2 USB interface is damaged. This helps users quickly determine whether the device is effectively connected to the docking station 2. The indication component 234 can be provided with a data transmission indication light, which reflects the real-time state of data transmission through the flashing frequency. When a large amount of data transmission is performed, such as copying large files, the indication light will flash quickly, indicating that data is being transmitted at high speed; when data transmission is completed or paused, the indication light may stop flashing or resume a slow flashing frequency. Users can observe the indication light to intuitively understand the data transmission progress and determine whether the transmission is proceeding normally. For example, during the process of copying files to a mobile hard disk, if the indication light suddenly stops flashing, it may mean that the data transmission is interrupted, and the cause needs to be checked in time. The indication component 234 can be provided with a network status indication light, which is used to display the wired network connection state. A constant light indicates that the network physical connection is normal and has successfully connected to the local area network; a flashing light indicates that there is network data being transmitted. If the indication light is not on, it may be that the network cable is not inserted properly, the network interface is faulty, the router setting problem or the network service is interrupted.

[0052] As Figure 9 , Figure 10 and Figure 11As shown, the second side of the carrier 231 is provided with an expansion module 236, the second side of the carrier 231 being the side facing away from the user, the expansion module 236 including at least a 2-way USB (Universal Serial Bus) 2.0 interface, a 1-way USB 3.0 interface, a 1-way DDI (Data Distribution Interface) interface, and a 1-way PCIe (Peripheral Component Interconnect Express) x1 interface. The USB 3.0 interface is directly led out. The DDI interface realizes a 1-way HDMI (High-Definition Multimedia Interface) interface. One of the USB 2.0 interfaces realizes a 1-way RS232 (Recommended Standard 232) interface through a USB-to-serial chip. The other USB 2.0 interface is expanded into 3-way external USB 2.0 interfaces and a 1-way internal expansion slot (a USB interface connected to the miniPCIe connector 22) through a HUB (Network Hub) for expanding a DIO (Digital Input / Output) module of the USB interface. The PCIe x1 interface is expanded into two PCIe x1 interfaces through a PCIe bridge, one of which realizes a 1-way Gigabit Ethernet through a network chip, and the other PCIe is used for a 1-way internal miniPCIe expansion slot.

[0053] The docking station 2 further includes at least one HDMI interface, three USB 2.0 interfaces, one USB 3.0 interface, one 10 / 100 / 1000BaseT Gigabit Ethernet LAN, one RS232 / RS422 / RS485 interface, one expandable mSATA solid state disk, 128GB-1TB optional, two miniPCIe expansion slots, each slot having a PCIe 2.0 x1 and a USB 2.0 bus, and the slot can be installed with a standard length card or a double length card, one of the slots uses the PCIe bus to realize a 1553B expansion module, and the other slot uses the USB bus to realize a DIO expansion module. The docking station 2 needs to meet the demand for high-speed data transmission, and the circuit board 24 adopts high-speed circuit design and high-performance chips to ensure that data is quickly and stably transmitted between different interfaces. For example, when transmitting a large-capacity file through the USB interface of the docking station 2, the circuit board 24 can ensure the data transmission rate, reduce the transmission time, and avoid data loss or errors. In the USB 3.0 and above standard interface, the circuit board 24 can support a transmission rate of up to 5Gbps or even higher.

[0054] As shown in FIG. 1, the docking station 2 includes a circuit board 24, a power supply 25, and a plurality of connectors 26. Figure 10 and Figure 11As shown, the expansion module 236 in the docking station 2 is specifically an mSATA hard disk expansion port realized by a SATA (Serial ATA) interface, which can expand the hard disk capacity when the docking station is used. A USB2.0 interface and a USB-to-serial chip are used to realize an RS232 interface, which is led out of the docking station 2. A USB HUB is used to control one USB2.0 interface into four, of which three are led out of the docking station 2, and one is used to control the DIO module. One USB3.0 interface is directly led out of the docking station 2. One DDI interface is used as an HDMI display interface and is led out of the docking station 2. One PCIe2.0x1 interface is expanded into two by a PCIe SWITCH chip, of which one is connected to a network chip and expanded into a gigabit network and led out of the docking station 2, and the other is used as a miniPCIe socket, in which a 1553 module is inserted. The 1553 expansion module takes an ARTIX7 series FPGA chip of xilinx as the core, connects the PCIe bus of the miniPCIe socket through the PCIe interface of the FPGA, expands an SDRAM memory outside the FPGA as a cache, and connects an external crystal oscillator as a module clock. The FPGA logic realizes a single-channel full-featured 1553 IP core, which has the functions of BC, MT and up to 31 enable / disable RTs. The IO interface of the FPGA is connected to a 1553 transceiver chip, which realizes two redundant 1553 buses through an isolation transformer and is led to the surface of the docking station 2 through an aviation plug. The DIO expansion module takes the USB bus of the miniPCIe socket and accesses an FT232H chip, and the IO and read-write control ports of the FT232H chip are connected to the FPGA. The FPGA logic realizes a functional circuit control function, which realizes four 32V / ground level optocoupler isolation input channels and four 28V / ground level relay switching output channels. The input and output channels of the DIO expansion module are led to the surface of the docking station 2 through an aviation plug.

[0055] Accordingly, the portable expandable tablet computer can be used as a portable mobile computing device, and can also be plugged into the docking station 2 to realize 1553 communication and DIO measurement and control functions, realizing flexible combination of functions.

[0056] The connecting piece 232 is arranged on the first side of the bearing piece 231, and the connecting piece 232 is inclined from the first side to the second side, facilitating display operation. The docking station 2 has an outer dimension of 303mm (length) x 126mm (width) x 103mm (height), the whole machine has a power consumption of not more than 25W, the power supply uses a 12V 90W AC-DC industrial adapter, and the whole machine has a weight of ≦1.0Kg.

[0057] The docking station 2 also includes a circuit board 24, the indication assembly 234, the switch assembly 235 and the expansion module 236 are connected with the circuit board 24, the circuit board 24 of the docking station 2 is connected and controls various indicator lights, and the working condition of the docking station 2 is fed back to the user through the state of the indicator light. For example, the power indicator light shows whether the docking station 2 is powered on, the connection state indicator light indicates whether the device is successfully connected, and the data transmission indicator light reflects the real-time state of data transmission. The circuit board 24 controls the on-off, flicker frequency and the like of the indicator light according to the running state of the internal circuit, and provides intuitive working state information for the user. The circuit board 24 receives control signals from the host 1 or user operation, and realizes control of the function of the docking station 2. The host 1 can also remotely control the docking station 2 through software, and the circuit board 24 is responsible for executing these control instructions.

[0058] The expansion module 236 of the docking station 2 provides more interfaces for the device, and the circuit board 24 can expand multiple USB interfaces for connecting mouse, keyboard, mobile hard disk and the like from the limited interfaces of the host 1, and simultaneously provides an HDMI interface to realize large-screen display of an external display. The circuit board 24 of the docking station 2 needs to perform signal conversion and adaptation to ensure that data can be accurately transmitted between different interfaces. For example, the DDI signal output by the host 1 is converted into a video signal required by the HDMI interface, so as to output the computer picture to the external display. Such conversion not only involves matching of signal level, but also includes conversion of data format and protocol, and the chips and circuits on the circuit board 24 are responsible for completing these complex conversion operations.

[0059] The circuit board 24 of the docking station 2 can recognize the device type and parameters connected to each interface. Through communication with the host 1, it transmits device information to the host 1 operating system, so that the host 1 can correctly identify and install the corresponding driver program to realize normal work of the device. For example, when the user inserts a U disk into the USB interface of the docking station 2, the circuit board 24 detects the attributes of the U disk and transmits these information to the host 1, and the host 1 loads the driver program of the U disk according to these information, so that the data in the U disk can be accessed.

[0060] The circuit board 24 of the docking station 2 needs to process different interfaces to follow different communication protocols to ensure that the devices can effectively communicate. It is responsible for parsing and generating data frames conforming to the corresponding protocol to realize correct sending and receiving and interaction of data. For example, when connecting the network through the RJ45 network interface of the docking station 2, the circuit board 24 needs to process network data according to the Ethernet protocol to ensure smooth network communication.

[0061] The expansion module 236 can provide multiple connection and usage modes, and be applied to multiple different usage scenarios. When transmitting large files such as high-definition videos and large game installation packages, stable connection is crucial. The locking connection can prevent transmission errors or interruptions caused by loose interfaces, and ensure complete and accurate data transmission. When connecting the host 1 and the storage device through the docking station 2, reliable connection can avoid file loss or damage during file transmission, and ensure smooth work. The locking connection can ensure the stability of data transmission between devices.

[0062] The connection side 121 of the host shell 12 is arranged at the intersection of the first face 122 and the second face 123 of the host shell 12, and has a first connection edge 1211 and a second connection edge 1212 in a stepped shape. The length of the first connection edge 1211 in the first direction is greater than the length of the second connection edge 1212 in the first direction. The locking port 13 and the connection interface 14 are both located on the first connection edge 1211. The connection part 23 has a third connection edge 2311 and a fourth connection edge 2312 corresponding to the first connection edge 1211 and the second connection edge 1212. The first connection edge 1211 and the second connection edge 1212 are arranged in a concave shape, and the third connection edge 2311 and the fourth connection edge 2312 are arranged in a convex shape, providing accurate positioning. During assembly, the convex and concave parts fit closely, limiting the movement of the parts in various directions, allowing the parts to be accurately installed at the predetermined position. The concave-convex structure is embedded in each other, increasing the friction and engagement force between the parts, effectively preventing the parts from loosening under external forces such as vibration and impact. When the parts are subjected to external forces, the concave-convex structure can evenly distribute the stress to the entire connection area, avoiding stress concentration in a certain point or area.

[0063] The host 1 further comprises a mainboard and a power supply module. The power supply module is electrically connected to the mainboard for supplying power to the display screen 11 and the docking station 2. The power supply module can be a lithium battery or a power storage device that provides power. The mainboard is electrically connected to the display screen 11, and the mainboard is electrically connected to the connection interface 14. The connection interface 14 and the connector 22 are electrically connected to make the docking station 2 a functional expansion carrier. When the docking station 2 is not connected to a power source, the power supply module can supply power to the docking station 2.

[0064] The docking station 2 is provided with a battery. When the host 1 is charging through the docking station 2, stable connection can ensure uninterrupted charging. For users who often use the host 1 in a mobile state, such as during product demonstrations, the locking connection can prevent charging from being interrupted due to walking, placing, and other actions, ensuring that the host 1 has sufficient power and maintains normal use.

[0065] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
