Description

Technical Field

[0001] The utility model relates to the technical field of shared equipment, in particular to a USB shared equipment used for conference delegates. Background Art

[0002] In order to save paper and reduce meeting costs, relevant materials will be copied to the on-site host before the meeting starts to facilitate display during the meeting. However, this method of collecting meeting materials has poor flexibility and is prone to problems such as missed or wrong copying of materials. In addition, this method is often troublesome when participants need to access USB devices temporarily during the meeting. If the wires are laid directly on the conference table, it will greatly affect the overall appearance of the conference table. If a USB-HUB is placed on the conference table, it will cause problems such as insufficient power supply and complexity of resource positioning after multiple USB devices are inserted at the same time. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: a USB sharing device for conference participants, comprising a connector and a connection controller, the front of the connector is sequentially provided with a USB socket, a working status light and a connection / disconnection micro switch, the back of the connector is sequentially provided with a first front-stage USB port, a first rear-stage USB port, a 3.5mm power socket and an XH3P control line socket, a fixed installation hole is opened on the surface of the connector, the front of the connection controller is provided with a configuration status light, a configuration micro switch, a connection status light, a previous micro switch and a subsequent micro switch, the two sides of the connection controller are respectively provided with a second rear-stage USB port and a second front-stage USB port, and the side of the connection controller is provided with an XH2P control line socket.

[0005] Preferably, the connector and the connection controller both include an MCU control unit, a power supply unit, an indication unit and a key detection unit, the connector also includes an interface routing unit, a front-end interface detection unit, an external bus and a rear-end interface unit, and the connection controller also includes an external bus interface unit. Here, the number of units of the connector and the connection controller is determined.

[0006] Preferably, the step-down circuit of the power supply unit is specifically 5V / 3A, 3.3V / 100mA. Here, the step-down circuit of the power supply unit is determined.

[0007] Preferably, the connectors and the connection controllers are arranged in a ratio of N: 1. Here, a plurality of connectors may be controlled by one connection controller.

[0008] Preferably, the number of the fixing and mounting holes is two groups, and the two groups of fixing and mounting holes are symmetrically distributed on the surface of the connector. Here, the connector can be fixed to a suitable position.

[0009] Compared with the prior art, the advantages and positive effects of the utility model are:

[0010] In the utility model, mutually exclusive connection between multiple USB devices and the host is achieved through the hand-in-hand USB wiring method. Application in the conference can greatly optimize the user experience of the delegates, improve the efficiency of meeting resource aggregation, and avoid the shortcomings of the traditional meeting in the resource aggregation method. The working principle of the connector is not the traditional USBHUB, and will not increase the number of USBHUB nodes on the conference host. It is not subject to the five-level cascade limit of the USBHUB, only occupies one device port, and is not affected by the power supply current of the USBHUB. Since only one USB device is connected to the host at a time, the complexity of resource positioning caused by multiple devices connecting to the conference host at the same time is reduced. The hand-in-hand deployment method also reduces the complexity and deployment cost of system deployment. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] Embodiment 1

[0030] See also Figure 1-14 The utility model provides a technical solution: a USB sharing device for conference delegates, including a connector 1 and a connection controller 2, the front of the connector 1 is sequentially provided with a USB socket 11, a working status light 12 and a connection / disconnection micro switch 13, the back of the connector 1 is sequentially provided with a first front-stage USB port 14, a first rear-stage USB port 15, a 3.5mm power socket 16 and an XH3P control line socket 17, the surface of the connector 1 is provided with fixed mounting holes 18, the number of the fixed mounting holes 18 is two groups, and the two groups of fixed mounting holes 18 are symmetrically distributed on the surface of the connector 1.

[0031] The USB socket 11 is used for conference delegates to insert USB devices. The working status light 12 is always green, indicating that the first front-stage USB port 14 is connected to the first rear-stage USB port 15. The working status light 12 is always red, indicating that the USB socket 11 is connected to the first front-stage USB port 14. If the LED is off, it proves that the first front-stage USB port 14 is not connected and the problem needs to be checked. When the connect / disconnect micro switch 13 is pressed, a signal path between the USB socket 11 and the first front-stage USB port 14 can be established, or a signal path between the first front-stage USB port 14 and the first rear-stage USB port 15 can be established. The 3.5mm power socket 16 is used to connect to a 12V / 2A power supply, and the XH3P control line socket 17 is used to connect to RVSP*2 control cables.

U3 is responsible for stepping down the external 12V to 3.3V to power the MCU. After the current USB is inserted into the first front USB port 14, Fig. 9 The voltage-dividing detection point formed by R31 and R32 provides the front-stage USB insertion signal to the MCU so that the MCU can start the access process and complete the initialization configuration. After the MCU of connector 1 completes the configuration, it Fig.11 The USB-EN end supplies power to the subsequent stage to complete a handle transaction.

[0035] When the user operates the micro switch of the connector, if the working state is normal, the MCU Figure 8 The sending control model realizes the connection between the USB device and the front-stage USB signal. The ultra-high-speed multi-channel analog switch with USB signal conditioning makes the USB device work stably. Figure 6 The D1 uses RGBLED, which has 255 levels of brightness display for red, green and blue colors, which can intuitively distinguish each working state.
