BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to virtual reality (VR) connection devices, and more particularly, to an active virtual reality cable.

2. Description of the Related Art

When an electronic device works with an internally existing power, such electronic device is defined as an active device, so that the active device is allowed to achieve certain functions with an aid of the power energy. Active device includes two categories, mainly discrete device and integrated circuit. An active cable refers to a communication device which depends on an external power to transmit signal and data during the communication process. Active cables are usually applied for signal amplification or transformation. With the development of virtual reality (VR) market, consumers are progressively paying attention to a three-dimensional and dynamically immersive experience formed of games, videos, and social interaction. In high-end VR products, the connection hardware between a high performance host machine and the VR headset imposes a significant effect upon the product performance. Previously, at least two to three video cables, such as high definition multimedia interface (HDMI), universal serial bus (USB) or DC cables, are tied into a bundle to be applied together for VR equipment connection.

SUMMARY OF THE INVENTION

For improving the issues above, a cable is provided as a connection resolution between the virtual reality (VR) headset and a computer host machine. The cables combines various kinds of signal wires and a power cable, so as to be easily applied and stored, and the cost thereof is lowered.

For achieving the aforementioned objectives, an active virtual reality cable in accordance with an embodiment of the present invention is provided for connecting a motherboard of the virtual reality equipment and a personal computer, the active virtual reality cable comprising, a main wire, a plurality of wire branches, a transfer member, and a control member.

The transfer member connects the main wire and the plurality of wire branches. The transfer member is a printed circuit board which comprises a first transfer end connected with one end of the main wire and a second transfer end connected with one end of the plurality of wire branches, respectively. The plurality of wire branches have another end thereof connected with the personal computer.

The control member is connected with another end of the main wire, so that the control member is connected with the virtual reality equipment. The connection port between the control member and the motherboard of the virtual reality equipment is in a form selected from a group consisting of an integrated circuit (IC) module, a 42-pin input/output socket, and a video socket.

Preferably, the wires of the wire branch are selected from the group consisting of a high definition multimedia interface (HDMI), universal serial bus (USB), DisplayPort (DP), Type C, and a combination thereof.

Preferably, the active virtual reality cable includes an extension wire which is a passive cable, with one end thereof connected with the control member through an OCulink plug, such that the control member is connected with the motherboard of the virtual reality equipment through the extension wire.

Preferably, the transfer member further includes an extensive power socket.

Preferably, the control member includes a first plug end having an engage space. The extension wire includes a second plug end having a hook end and a press end. The hook end is resilient and disposed at the position corresponding to the engage space. The press end extends from the hook end and protrudes out of the first plug end.

When the control member and the extension wire are combined together through the first plug end and the second plug end, the hook end is stably clamped in the engage space. When the press end is imposed with a downward external force, the hook end is triggered to leave the engage space.

With such technical resolution, by use of the switch card in the transfer member, the active virtual reality cable in accordance with an embodiment of the present invention is allowed to combine a DC wire with multiple signal wires, such as HDMI, USB, DP or Type C wires, so as to increase the functions of a singular cable, which meets the developing trend of product digitalization and integration. The multi-sectional structure formed of the main wire, the wire branch, and the extension wire facilitates the storing and replacing process of the cable, thus meeting various usage requirements of the customers nowadays. The extension wire is connected with the main wire through the 42-pin OCulink plug, so as to improve the extension distance of the cable. Also, the cost of manufacturing is lowered, which makes the cable more competitive in the market.

DETAILED DESCRIPTION OF THE INVENTION

The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

Referring to FIG. 1 to FIG. 5, several embodiments of the present invention are provided for illustrating the technical features of the present invention.

Embodiment 1

Referring to FIG. 1 to FIG. 3, an active virtual reality (VR) cable is provided for connecting a motherboard 40 of a virtual reality equipment and a personal computer 50, the active virtual reality (VR) cable includes a main wire 1, a plurality of wire branches 2, a transfer member 11, and a control member 12.

The transfer member 11 is connected with the main wire 1 and the plurality of wire branches 2, respectively. The transfer member 11 is a printed circuit board and comprises a first transfer end 111 connected with an end of the main wire 1 and a second transfer end 112 connected with an end of the plurality of wire branches 2, respectively. The plurality of wire branches 2 have another end thereof connected with the personal computer 50. It is noted that the plurality of wire branches may also include a direct current (DC) power cable for connecting a direct current power source, so as to directly provide the power needed for the motherboard 40 or other circuits of the virtual reality equipment.

The control member 12 is connected to another end of the main wire 1, so as to be connected with the motherboard 40 of the virtual reality equipment.

The wire branches 2 include at least two wires selected from the group consisting of a high definition multimedia interface (HDMI), universal serial bus (USB), DisplayPort (DP), Type C wire, or any combination thereof.
