The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] like Figure 1 As shown, the present invention provides a virtual reality system 10, which can be applied to a virtual reality device to achieve switching between two working modes: a PC-VR mode and an all-in-one mode, thereby outputting high-resolution video images.

[0040] In one embodiment of the present invention, Figure 1 As shown, the virtual reality system 10 includes a first conversion module 101, an integrated machine control module 103, a switching module 102 and an output device 104. The first conversion module 101 is used to connect a computer device, such as a PC 20, to perform a signal conversion operation on the video signal received by the DP interface, and output a first video signal. The integrated machine control module 103 itself can output a second video signal; the first video signal and the second video signal are both video signals that can be normally received and displayed by the output device. The integrated machine control module 103 is also electrically connected to the first conversion module 101 to control the operation of the first conversion module 101. The switching module 102 is electrically connected to the first conversion module 101 and the integrated machine control module 103, respectively, and performs a switching operation of the working mode according to the control instruction of the integrated machine control module 103, so as to receive the first video signal of the first conversion module 101 in the PC-VR mode, or receive the second video signal of the integrated machine control module 103 in the integrated machine mode according to the use needs, so as to realize the switching operation of the dual working modes. The output device 104 is electrically connected to the switching module 102 . The switching module 102 transmits a video signal to the output device 104 , and displays a corresponding video image through the output device 104 .

[0041] Among them, in PC-VR mode, the switching module 102 receives the first video signal output by the first conversion module 101, transmits the first video signal to the output device 104, and displays the corresponding video picture; in the all-in-one mode, the switching module 102 receives the second video signal output by the all-in-one control module 103, transmits the second video signal to the output device 104, and displays the corresponding video picture.

[0042] It should be noted that the electrical connection described in the embodiments of the present invention includes but is not limited to a communication connection. Specifically, the communication connection includes a wired communication connection and a wireless communication connection.

[0043] When the virtual reality system 10 of the present invention is applied to a virtual reality device, the PC-VR mode and the all-in-one mode are independent of each other, and can normally transmit a high-resolution video signal (such as a 4K video signal) output by the PC 20, thereby displaying a high-resolution video image without causing a drop in resolution, and without occupying the USB interface of the all-in-one, which can effectively improve the user experience. In addition, the all-in-one control module 103 can control the switching module 102 according to the use needs, and perform corresponding mode switching operations, and the mode switching efficiency is higher.

[0044] In some embodiments of the present invention, Figure 2 As shown, the first conversion module 101 specifically includes a first conversion chip 1011, a first signal input port 1012, and a first signal output port 1013. The first conversion chip 1011 is connected to the first signal input port 1012 and the first signal output port 1013, respectively, to facilitate signal input and output. The first signal input port 1012 is used to connect to the PC 20 to receive a video signal, especially a high-resolution video signal (such as a 4K video signal); under the control of the all-in-one control module 103, the first conversion chip 1011 converts the video signal received by the DP interface into a first video signal, which is a video signal that can be received by MIPI DSI, and transmits it to the switching module 102 through the first signal output port 1013. Compared with the existing virtual reality device, in the PC-VR mode, the video signal received by the DP interface does not need to be transmitted through the all-in-one control module 103, so that the resolution of the video signal will not be reduced, and the high-definition video picture can be directly displayed, with better effect. Among them, the first signal input port 1012 can be a DP interface, which is more versatile and convenient to use.

[0045] In some embodiments of the present invention, Figure 2As shown, the switching module 102 specifically includes at least one group of signal switching switches 1021, each group of signal switching switches 1021 has two signal switching switches, and the two signal switching switches 1021 are electrically connected to the same output device 104 to meet the specification requirements of the output device 104 and support high-resolution 4K video images; each signal switching switch 1021 is electrically connected to the all-in-one control module 103 to perform switching operations under the control of the all-in-one control module 103.

[0046] In some embodiments of the present invention, Figure 3 As shown, the signal switching switch 1021 is provided with a first switching port 1022 and a second switching port 1023. According to the use requirements, the all-in-one control module 103 sends a control instruction to the signal switching switch 1021. The signal switching switch 1021 controls the first switching port 1022 or the second switching port 1023 to be turned on according to the control instruction, so as to receive the first video signal when the first switching port 1022 is turned on, and receive the second video signal when the second switching port 1023 is turned on, so as to realize the independent operation of the two working modes and prevent the resolution of the video signal from being affected.

[0047] Specifically, Figure 3 As shown, the two first switch ports 1022 of each group of signal switching switches 1021 are electrically connected to the first signal output port 1013; in each group of signal switching switches 1021, any second switch port 1023 is electrically connected to the all-in-one control module 103. When it is necessary to work in the PC-VR mode, the signal switching switch 1021 controls the first switch port 1022 to be turned on according to the control instruction, and the first video signal is transmitted to the output device 104 in two signals through the two first switch ports 1022; when it is necessary to work in the all-in-one mode, the signal switching switch 1021 controls the second switch port 1023 to be turned on according to the control instruction, and the second video signal is transmitted to the output device 104 through the corresponding second switch port 1023.

[0048] Furthermore, if Figure 4 As shown, the output device 104 includes two first displays 1041, and correspondingly, the number of signal switching switches 1021 is also two groups, and each group of signal switching switches 1021 is electrically connected to a first display 1041 to transmit a video signal to the first display 1041. When a 4K video signal is transmitted in the PC-VR mode, dual 4K high-definition video screen display can be achieved, with better picture effects, which can effectively improve the user experience.

[0049] In some embodiments of the present invention, Figure 5As shown, the integrated machine control module 103 includes an integrated machine main control chip 1031, and the integrated machine main control chip 1031 is provided with at least one integrated machine signal output port 1032. A second switch port 1023 in each group of signal switching switches 1021 is electrically connected to the integrated machine signal output port 1032 to receive the second video signal in the integrated machine mode. Figure 5 In the example in the embodiment, the number of signal switching switches 1021 is two groups, and correspondingly, the number of all-in-one machine signal output ports 1032 is also two. Of course, depending on the number of displays of the output device 104 and the number of groups of signal switching switches 1021, the number of all-in-one machine signal output ports 1032 may also be one or more, and is not limited to the example in this embodiment. It should be noted that since the main control chip of the existing virtual reality all-in-one machine generally supports two output devices 104, the solution in this embodiment can make full use of the interface configuration of the existing virtual reality all-in-one machine to maximize the user experience.

[0050] In some embodiments of the present invention, the virtual reality system 10 further includes a second conversion module 105 and two second displays 1042. The second conversion module 105 specifically includes a second conversion chip 1051 and a second signal input port 1052 and a second signal output port 1053 electrically connected to the second conversion chip 1051; the second signal input port 1052 is used to be electrically connected to a computer device such as a PC 20, and the second conversion chip 1051 can convert the video signal received by the DP interface into a video signal received by MIPIDSI; the second signal output port 1053 is electrically connected to the two second displays 1042 to transmit the converted video signal to the two second displays 1042, and display the corresponding video screen through the second displays 1042. The second conversion module 105 and the second display 1042 in this embodiment can be used as a supplement to the all-in-one mode. According to the use needs, in the all-in-one mode, the video signal from the PC 20 is simultaneously displayed through the second display 1042, which can provide users with more choices and help to further improve the user experience.

[0051] In some embodiments of the present invention, the first display 1041 may be a 4K liquid crystal display (4K LCD) (eg Figure 6 As shown), or, the first display 1041 can also be a 4K light emitting diode display (4K LED display) to support the display of 4K video images.

[0052] Furthermore, the second display 1042 may also be a 4K liquid crystal display (4K LCD) or a 4K light emitting diode display (4K LED display).

[0053] Of course, the first display 1041 or the second display 1042 may also adopt other forms of video display devices, and is not limited to the examples in this implementation.

[0054] In some embodiments of the present invention, Figure 7 As shown, the virtual reality system 10 further includes an input module 106. The input module 106 is electrically connected to the all-in-one machine control module 103. The input module 106 can be used to input instruction information to trigger a mode switching instruction. After receiving the mode switching instruction, the all-in-one machine control module 103 sends a corresponding control instruction to the switching module 102 to control the switching module 1025 to perform a mode switching operation. Specifically, the input module 106 includes but is not limited to an operation button, a switch, a PC (such as a desktop computer, a laptop computer, a tablet computer, etc.) or a terminal device (such as a mobile phone, a handheld computer, etc.) with a software input interface; in addition, the electrical connection between the input module 106 and the all-in-one machine control module 103 can be a communication connection formed in a wired or wireless manner.

[0055] The following is a specific embodiment of the virtual reality system of the present invention:

[0056] like Figure 8 As shown, the virtual reality system 10 includes a first conversion module 101, an integrated machine control module 103, a switching module 102, an output device 104 and an input module 106. The first conversion module 101 specifically includes a first conversion chip 1011, a first signal input port 1012 and a first signal output port 1013.

Specifically, the two first switching ports 1022 of each group of signal switching switches 1021 are electrically connected to the first signal output port 1013, and in each group of signal switching switches 1021, any one of the second switching ports 1023 is electrically connected to the integrated machine signal output port 1032 of the integrated machine control module 103. The two signal switching switches 1021 of each group are electrically connected to the same first display 1041.

[0058] The input module 106 is electrically connected to the all-in-one control module 103 and is used to input instruction information that can trigger the mode switching instruction. The input module 106 includes but is not limited to an operation button, a switch, a PC with a software input interface (such as a desktop computer, a laptop computer, a tablet computer, etc.) or a terminal device (such as a mobile phone, a handheld computer, etc.)

[0059] In the working state, the first signal input port 1012 is electrically connected to the PC 20. When it is necessary to work in the PC-VR mode, the command information can be input through the input module 106 to trigger the corresponding mode switching command; after receiving the corresponding mode switching command, the all-in-one main control chip 1031 sends a control command to the switch 1021, and the signal switch 1021 controls the first switch port 1022 to be turned on according to the control command, and the first signal input port 1012 receives the video signal of the PC 20, and the first conversion chip 1011 converts the signal received by the DP interface into MIPI The DSI receives the video signal and outputs it through the first switching port 1022 in the form of a first video signal. The first video signal is transmitted to the first display 1041 through the signal switching switch 1021, and the corresponding video screen is displayed. When it is necessary to work in the all-in-one mode, the instruction information can be input through the input module 106 to trigger the corresponding mode switching instruction. After the all-in-one main control chip 1031 receives the corresponding mode switching instruction, it sends a control instruction to the signal switching switch 1021. The signal switching switch 1021 controls the second switching port 1023 to be turned on according to the control instruction. The second video signal output by the all-in-one main control chip 1031 through the all-in-one signal output port 1032 is transmitted to the first display 1041 through the second switching port 1023 and the signal switching switch 1021, and the corresponding video screen is displayed. Among them, the second video signal is the video signal received by MIPIDSI.

[0060] Furthermore, the virtual reality system 10 also includes a second conversion module 105 and two second displays 1042.

[0061] Among them, the first display 1041 and the second display 1042 are both 4K liquid crystal displays (4KLCD).

[0062] In one embodiment of the present invention, a virtual reality device 30 is also provided. Fig. 9 As shown, the virtual reality device 30 includes the virtual reality system 10 in any of the above embodiments to realize the switching between the two working modes of PC-VR and the all-in-one machine, so as to meet different usage needs. Since the two working modes operate independently of each other, when in the PC-VR mode, the PC 20 outputs a high-resolution video signal (such as a 4K video signal), the first conversion module of the virtual reality system can convert the video signal received by the DP interface into a video signal received by MIPI DSI, and transmit it to the output device 104. The resolution of the video signal is not affected during the transmission process, and the output device 104 can normally display the high-resolution video picture, and the picture effect is better, which can effectively improve the user experience. In addition, there is no need to occupy the USB interface of the all-in-one machine, and the structure and interface configuration of the existing virtual reality all-in-one machine can be fully utilized, which is conducive to reducing the design and modification costs.

[0070] In this embodiment, through step S110 to step S120, the target working mode corresponding to the mode switching instruction is first determined, and through step S130, the target working mode is compared and confirmed with the all-in-one mode to determine the direction of the mode switching operation, that is, switching from the all-in-one mode to the PC-VR mode (that is, the working mode of the virtual reality device connected to the PC), or switching from the PC-VR mode to the all-in-one mode. If the target working mode is the all-in-one mode, the control switching module runs in the all-in-one mode. If the target working mode is not the all-in-one mode, it indicates that the target working mode is the PC-VR mode, and the control switching module runs in the PC-VR mode. Among them, the input form of the switching operation instruction includes but is not limited to voice input, interface input, and button input.
