Problems solved by technology

[0003] At present, the external devices connected to the notebook computer are affected by the limited output current / voltage / power of the notebook computer’s USB interface, which affects the realization of some functions of the external equipment. Most of the interfaces are USB3.0 interfaces. The maximum output current / voltage / power of USB3.0 interface is 900mA / 5V / 4.5W. In order not to exceed the maximum output current / voltage / power of USB3.0 interface, the needs of headsets are continuously reduced. Cooperate with the functions realized by the computer to reduce the output power consumption of the computer's USB interface, which seriously affects the realization of more functions and better experience with PC head-mounted display devices

Abstract

The invention discloses an adapter and a PC-based head-mounted display system, the invention relates to the technical field of USB interface. The adapter comprises a power input terminal, a power output terminal and a plurality of adapter USB interfaces, a step-down control module, a step-down rectification module and a DC voltage output module are arranged between the power input terminal and theadapter USB interface, and the adapter USB interface comprises a USB master interface for transmitting data and a USB slave interface for transmitting data and supplying power; In PC-based headset display system, the USB master interface of adapter is connected to the USB interface of computer, and the USB slave interface of adapter is connected to the head-mounted display device. The adapter ofthe invention can realize the functions of increasing the maximum output current / voltage / power of the USB interface and extending the number of USB interfaces, and the head-mounted display device of the external computer based on the PC head-mounted display system can realize more functions by using the adapter.

Description

technical field [0001] The invention relates to the technical field of USB interface, in particular to an adapter and a PC-based head-mounted display system. Background technique [0002] USB is the abbreviation of Universal Serial Bus (Universal Serial Bus) in English. It is an external bus standard used to standardize the connection and communication between computers and external devices. The plug-and-play and hot-swap functions of the USB interface are widely used. In information and communication products such as personal computers and mobile devices, and expanded to photographic equipment, digital TV (set-top boxes), game consoles and other related fields, at present, the USB3.0 interface is widely used. [0003] At present, the external devices connected to the notebook computer are affected by the limited output current / voltage / power of the notebook computer’s USB interface, which affects the realization of some functions of the external equipment. Most of the inter...
