[0026] Figure 1 This is a schematic diagram of the structure of a data transmission line according to an embodiment of this application. Figure 7 This is a schematic diagram of the structure of an extended reality device according to one embodiment of this application. Figure 1 and Figure 7As shown, in one aspect, this application provides a data transmission line for connecting a head-mounted display 100 and a signal source 200. The data transmission line includes a cable 1, a first connector 2, at least one second connector 3, and a compensation module. The first connector 2 is connected to the cable 1 and configured to connect to the head-mounted display 100. The at least one second connector 3 is connected to the end of the cable 1 away from the first connector 2 and configured to connect to the signal source 200. The at least one second connector 3 is capable of transmitting at least one data signal. The compensation module is used to compensate for signal attenuation of the at least one data signal.

[0027] The data transmission line provided in this embodiment has a first connector 2 at one end of the cable 1 and at least one second connector 3 at the other end. In actual use, the first connector 2 establishes a physical and electrical connection with the head-mounted display 100, while the at least one second connector 3 connects to the signal source 200. Thus, the data transmission line effectively establishes a stable electrical connection path between the head-mounted display 100 and the signal source 200, thereby supporting the reliable transmission of at least one data signal from the signal source 200 to the head-mounted display 100. To ensure the transmission quality of the data signal, the data transmission line also includes a compensation module. This compensation module can monitor in real time the signal attenuation that may occur during the transmission of at least one data signal through the cable 1 and automatically compensate for the detected signal attenuation. Through this mechanism, the compensation module significantly improves the transmission performance of the data transmission line, effectively reducing signal attenuation loss due to distance or interference, thereby ensuring the transmission quality and reliability of the data signal from the signal source 200 to the head-mounted display 100.

[0028] It should be noted that head-mounted display 100 refers to a head-mounted display device, such as head-mounted mixed reality glasses. Signal source 200 can be a device such as a computer, tablet, or mobile phone.

[0029] The compensation principle of the compensation module is existing technology and will not be elaborated here. For example, the compensation module may include a signal monitoring chip and a signal amplifier. The signal monitoring chip can monitor the attenuation of the data signal, and the signal amplifier can amplify the corresponding data signal to its pre-attenuation state or a specific range based on the signal attenuation level fed back by the signal monitoring chip.

[0030] Figure 2 This is a schematic diagram illustrating the structure of at least one first compensation module according to an embodiment of this application. Figure 1 and Figure 2As shown, in some embodiments, the wire 1 includes a first wire 11 and at least one second wire 12, wherein the first wire 11 is connected to a first connector 2, the second wire 12 is connected to the end of the first wire 11 away from the first connector 2, and at least one second wire 12 is connected to at least one second connector 3 in a one-to-one correspondence. The compensation module includes at least one first compensation module 4, at least one first compensation module 4 is connected to at least one second wire 12 in a one-to-one correspondence, the first compensation module 4 is connected to the first wire 11, and the first compensation module 4 is used to perform signal attenuation compensation for the data signals transmitted with the correspondingly connected second wire 12.

[0031] In this application embodiment, at least one first compensation module 4 and at least one second wire 12 are connected one-to-one, that is, each second wire 12 is provided with a corresponding first compensation module 4, so that signal attenuation compensation can be performed on the data signal transmitted by each second wire 12 to ensure the transmission quality and stability of the data signal of all second wires 12. The first compensation module 4 can further transmit the compensated data signal to the first wire 11 connected to it.

[0032] Figure 3 This is a schematic diagram illustrating the structure of at least one second compensation module according to an embodiment of this application. Figure 1 and Figure 3 As shown, since signal attenuation may still occur during data signal transmission within the first wire 11, the data signal transmission quality deteriorates. Therefore, in some embodiments, the compensation module further includes at least one second compensation module 5, located within the first connector 2. The at least one second compensation module 5 is used to compensate for signal attenuation of at least one data signal transmitted through the first wire 11.

[0033] Furthermore, at least one second compensation module 5 is provided in the first connector 2. The at least one second compensation module 5 can compensate for the signal attenuation of at least one data signal transmitted by the first wire 11, thereby ensuring the transmission quality and stability of the data signal of the first wire 11.

[0034] It is understandable that the data signal type transmitted by the first wire 11 is consistent with the data type transmitted by at least one second wire 12. For example, if at least one second wire 12 can transmit three types of data signals, then the first wire 11 can also transmit three types of data signals accordingly.

[0035] The lengths of the second wire 12 and the first wire 11 can be set as needed. For example, the lengths of the second wire 12 and the first wire 11 can be equal or unequal. For example, the length of the second wire 12 may be less than the length of the first wire 11, but this is not a limitation; for example, the length of the second wire 12 may also be greater than or equal to the length of the first wire 11.

[0036] In terms of specific dimensions, the length of the second wire 12 is greater than or equal to 3 meters and less than or equal to 4 meters. For example, the length of the second wire 12 can be 3 meters, 3.1 meters, 3.2 meters, 3.3 meters, 3.4 meters, 3.5 meters, 3.6 meters, 3.7 meters, 3.8 meters, 3.9 meters, 4 meters, etc., and can be specifically set as needed. The length of the first wire 11 is greater than 0 meters and less than or equal to 1 meter. For example, the length of the second wire 12 can be 0.1 meters, 0.2 meters, 0.3 meters, 0.4 meters, 0.5 meters, 0.6 meters, 0.7 meters, 0.8 meters, 0.9 meters, 1 meter, etc., and can be specifically set as needed.

[0037] The compensation methods of the first compensation module 4 and the second compensation module 5 can be the same or different. The compensation methods of the first compensation module 4 and the second compensation module 5 can be designed according to the lengths of the first cable 11 and the second cable 12. For example, when the length of the second cable 12 is less than the length of the first cable 11, such as the length of the second cable 12 being 0.5 meters and the length of the first cable 11 being 4 meters, the data signal attenuation is less when transmitted through the second cable 12 due to the smaller length. In this case, the first compensation module 4 can adopt a quantitative compensation method, that is, regardless of how much the data signal transmitted through the second cable 12 is attenuated, the first compensation module 4 performs quantitative compensation for the data signal transmitted through the second cable 12, which simplifies the compensation algorithm of the first compensation module 4. However, the first cable 11 is longer and closer to the head-mounted display 100, requiring more accurate data signals. In this case, the second compensation module 5 adopts a differentiated compensation method, that is, the second compensation module 5 compensates for the amount of attenuation of the data signal transmitted within the first cable 11, thereby ensuring the quality of the data signal transmitted to the head-mounted display 100. However, this is not the only option. For example, when the length of the second wire 12 is equal to the length of the first wire 11, both the first compensation module 4 and the second compensation module 5 can use differentiated compensation methods. As another example, when the length of the second wire 12 is greater than the length of the first wire 11, the first compensation module 4 can use a differentiated compensation method, while the second compensation module 5 can use a quantitative compensation method.

[0038] like Figure 1As shown, in some embodiments, at least one second wire 12 includes a first second wire 121, a second second wire 122, and a third second wire 123, and at least one second connector 3 includes a first second connector 31, a second second connector 32, and a third second connector 33. The first second connector 31 is connected to the end of the first second wire 121 away from the first connector 2, and the first second connector 31 is used to transmit a first data signal. The second second connector 32 is connected to the end of the second second wire 122 away from the first connector 2, and the second second connector 32 is used to transmit a second data signal. The third second connector 33 is connected to the end of the third second wire 123 away from the first connector 2, and the third second connector 33 is used to transmit a third data signal.

[0039] The first second connector 31, the second second connector 32, and the third second connector 33 can be connected to different interfaces of the signal source 200, respectively. The first second wire 121 is connected to the first second connector 31, the second second wire 122 is connected to the second second connector 32, and the third second wire 123 is connected to the third second connector 33. The first second wire 121, the second second wire 122, and the third second wire 123 are used to transmit the first data signal, the second data signal, and the third data signal, respectively, thereby improving the data bandwidth of the data transmission line.

[0040] The types of the first and second connectors 31, 32, and 33 can be configured as needed. For example, the types of the first and second connectors 31, 32, and 33 can be partially the same or completely different. For instance, the first and second connectors 31 can be a DP1.4 interface, the second and second connectors 32 can be a USB3.2 interface, and the third and second connectors 33 can be a USB2.0 interface. Correspondingly, the signal source 200 is provided with three different quick-connect interfaces, each corresponding to a DP1.4 interface, a USB3.2 interface, and a USB2.0 interface, respectively.

[0041] The first, second, and third data signals can be set according to the type of data signal to be transmitted. For example, the types of the first, second, and third data signals can be partially the same or completely different. For example, the first data signal is a video display data signal, the second data signal is a camera data signal, and the third data signal is a sensor data signal.

[0042] like Figure 1 and Figure 2As shown, at least one first compensation module 4 includes a first first compensation module 41, a second first compensation module 42, and a third first compensation module 43. The first first compensation module 41 is electrically connected to the first second wire 121 and is used to compensate for signal attenuation of the first data signal. The second first compensation module 42 is electrically connected to the second second wire 122 and is used to compensate for signal attenuation of the second data signal. The third first compensation module 43 is electrically connected to the third second wire 123 and is used to compensate for signal attenuation of the third data signal.

[0043] This design ensures that each data signal has a corresponding first compensation module 4 for signal attenuation compensation. Specifically, when the first data signal transmitted by the first and second wires 121 experiences signal attenuation, the first compensation module 41 compensates for the signal attenuation; when the second data signal transmitted by the second wire 122 experiences signal attenuation, the second compensation module 42 compensates for the signal attenuation; and when the third data signal transmitted by the third wire 123 experiences signal attenuation, the third compensation module 43 compensates for the signal attenuation. Therefore, each first compensation module 4 of this application can perform precise signal attenuation compensation for the data signal transmitted by a specific second wire 12, effectively improving the stability and reliability of data transmission.

[0044] Figure 4 This is a schematic diagram illustrating the structure of a first motherboard and a power adapter in accordance with one embodiment of this application. Figure 1 , Figure 4 and Figure 7 As shown, in some embodiments, the data transmission line further includes a first power supply module 6 and a first monitoring module 7, wherein the first power supply module 6 is used to supply power to at least one first compensation module 4, the first monitoring module 7 is electrically connected to at least one second connector 3, and the first monitoring module 7 is used to control the first compensation module 4 and the first power supply module 6 corresponding to the second connector 3 to disconnect when it detects that the second connector 3 and the signal source 200 are disconnected.

[0045] The first power supply module 6 can supply power to at least one first compensation module 4, ensuring the normal operation of the first compensation module 4. The first monitoring module 7 can monitor the connection status between the second connector 3 and the signal source 200. When the first monitoring module 7 detects that the second connector 3 and the signal source 200 are disconnected, it will immediately control the first power supply module 6 to stop supplying power to the first compensation module 4 corresponding to the disconnected second connector 3, preventing continued power supply from causing leakage in the second connector 3 and leading to serious safety problems, thus ensuring the stable and safe operation of the entire data transmission line.

[0046] It should be noted that the first monitoring module 7 can also monitor the connection abnormalities of the second connector 3, such as short circuits or poor contact. The first monitoring module 7 can quickly identify and issue an alarm signal, and at the same time transmit the relevant abnormal information to the signal source 200 so that the staff can carry out timely investigation and repair.

[0047] For example, the first monitoring module 7 can determine the connection status between the second connector 3 and the signal source 200 by monitoring the hot-plug detection signal status of the second connector 3. Specifically, when the second connector 3 is abnormally disconnected, that is, when the second connector 3 and the signal source 200 are in a disconnected state, the first monitoring module 7 will detect that the hot-plug detection signal changes from a high level to a low level. To improve detection accuracy, the duration of the low level detection can be set, for example, 3 seconds. If the hot-plug detection signal remains low after 3 seconds, it is determined that the second connector 3 has been disconnected from the signal source 200. Similarly, whether the hot-plug detection signal monitored by the first monitoring module 7 meets the high level requirement can be used to determine whether the second connector 3 has a connection abnormality. For example, if the hot-plug detection signal monitored by the first monitoring module 7 is higher than the low level but lower than the required high level, it is determined that the connection between the second connector 3 and the signal source 200 is abnormal (e.g., poor contact), and further investigation and repair are required.

[0048] Specifically, the first monitoring module 7 is electrically connected to the first second connector 31, the second second connector 32, and the third second connector 33. The first monitoring module 7 can simultaneously monitor the connection status of the first second connector 31, the second second connector 32, the third second connector 33, and the signal source 200. When the first monitoring module 7 detects that one or more of the first second connector 31, the second second connector 32, and the third second connector 33 are disconnected from the signal source 200, it can control at least one first compensation module 4 and the first power supply module 6 corresponding to the disconnection of one or more of the first second connector 31, the second second connector 32, and the third second connector 33.

[0049] For example, when the first monitoring module 7 detects that the first second connector 31 and the signal source 200 are disconnected, it controls the first first compensation module 41 and the first power supply module 6 corresponding to the first second connector 31 to disconnect, while the second first compensation module 42 and the third first compensation module 43 corresponding to the second second connector 32 and the third second connector 33, which are connected to the signal source 200, remain electrically connected to the first power supply module 6.

[0050] The first power supply module 6 can be a storage battery. The storage battery is electrically connected to the power adapter and can store a certain amount of electricity. It can provide continuous power to the first compensation module 4 for a period of time, without requiring the first compensation module 4 to be constantly connected to the external power adapter.

[0051] like Figure 1 and Figure 4 As shown, in some embodiments, the data transmission line further includes a first motherboard 8, a first cable 11 is connected to at least one second cable 12 through the first motherboard 8, a first compensation module 4, a first monitoring module 7 and a first power supply module 6 are all disposed on the first motherboard 8, the first motherboard 8 has a power supply interface 81, the power supply interface 81 is electrically connected to the first power supply module 6, and the power supply interface 81 is configured to be electrically connected to the power adapter.

[0052] A first motherboard 8 is configured, on which the first compensation module 4, the first monitoring module 7, and the first power supply module 6 are all integrated, improving the overall structural compactness. When the first power supply module 6 needs charging, the power adapter and the power interface 81 are electrically connected, and the power adapter charges the first power supply module 6. The first power supply module 6 can further supply power to the first compensation module 4 and the first monitoring module 7 through the first motherboard 8.

[0053] For example, the first motherboard 8 has multiple conductive traces, and the first power supply module 6 is electrically connected to the first compensation module 4 and the first monitoring module 7 through these conductive traces. A first control valve can be installed on the conductive trace between the first compensation module 4 and the first power supply module 6. The first control valve is electrically connected to the first monitoring module 7. During normal power supply, the first control valve is closed, ensuring the continuity of the conductive trace between the first compensation module 4 and the first power supply module 6. When the first monitoring module 7 detects that the second connector 3 and the signal source 200 are disconnected, the first monitoring module 7 controls the first control valve to open, thereby disconnecting the conductive trace between the first compensation module 4 and the first power supply module 6, preventing the first power supply module 6 from supplying power to the first compensation module 4.

[0054] Figure 5 This is a schematic diagram of the cross-sectional structure of a first wire according to an embodiment of this application. Figure 1 and Figure 5 As shown, in some embodiments, the first wire 11 includes a housing 111 and a first sub-wire 112, a second sub-wire 113 and a third sub-wire 114 wrapped inside the housing 111, wherein the first sub-wire 112 is connected to the first second wire 121, the second sub-wire 113 is connected to the second second wire 122, and the third sub-wire 114 is connected to the third second wire 123.

[0055] The first wire 11 is configured such that the first sub-wire 112 is connected to the first and second wires 121 for receiving and transmitting a first data signal, the second sub-wire 113 is connected to the second and second wires 122 for receiving and transmitting a second data signal, and the third sub-wire 114 is connected to the third and second wires 123 for receiving and transmitting a third data signal. The first sub-wire 112, the second sub-wire 113, and the third sub-wire 114 are encased in the same housing 111, which improves the compactness of the wire 1 and prevents the wires from becoming tangled and messy.

[0056] like Figure 1 , Figure 4 and Figure 5 As shown, the first sub-line 112, the second sub-line 113, and the third sub-line 114 are connected one-to-one with the first motherboard 8 and the first second wire 121, the second second wire 122, and the third second wire 123, respectively. Specifically, one side of the first motherboard 8 has three first pins, which are connected one-to-one with the first second wire 121, the second second wire 122, and the third second wire 123, respectively. The first first compensation module 41, the second first compensation module 42, and the third first compensation module 43 on the first motherboard 8 are connected to the three first pins one-to-one through multiple first conductive traces. The other side of the first motherboard 8 has three second pins, which are connected one-to-one with the first sub-line 112, the second sub-line 113, and the third sub-line 114, respectively. The first first compensation module 41, the second first compensation module 42, and the third first compensation module 43 on the first motherboard 8 are connected to the three second pins one-to-one through multiple second conductive traces.

[0057] At least one second compensation module 5 includes a first second compensation module 51, a second second compensation module 52, and a third second compensation module 53. The first second compensation module 51 is electrically connected to the first sub-line 112 and is used to compensate for signal attenuation of the first data signal. The second second compensation module 52 is electrically connected to the second sub-line 113 and is used to compensate for signal attenuation of the second data signal. The third second compensation module 53 is electrically connected to the third sub-line 114 and is used to compensate for signal attenuation of the third data signal.

[0058] This design ensures that each data signal transmitted on a sub-line has a corresponding second compensation module 5 for signal attenuation compensation. Specifically, when the first data signal transmitted on the first sub-line 112 experiences signal attenuation, the first and second compensation modules 51 can compensate for the signal attenuation; when the second data signal transmitted on the second sub-line 113 experiences signal attenuation, the second and second compensation modules 52 can compensate for the signal attenuation; and when the third data signal transmitted on the third sub-line 114 experiences signal attenuation, the third and second compensation modules 53 can compensate for the signal attenuation. Therefore, each of the second compensation modules 5 in this application can perform precise signal attenuation compensation for the data signal transmitted on a specific sub-line, effectively improving the stability and reliability of data transmission.

[0059] Figure 6 This is a schematic diagram illustrating the structure of a second motherboard and related structures in accordance with one embodiment of this application. Figure 3 , Figure 6 , Figure 7 As shown, in some embodiments, the data transmission line further includes a second power supply module 9 and a second monitoring module 10, wherein the second power supply module 9 is used to supply power to at least one second compensation module 5, the second monitoring module 10 is electrically connected to the first connector 2, and the second monitoring module 10 is used to control the second compensation module 5 and the second monitoring module 10 to disconnect when the second connector 32 and the head-mounted display 100 are detected to be disconnected.

[0060] The second power supply module 9 can supply power to at least one second compensation module 5, ensuring the normal operation of the second compensation module 5. The second monitoring module 10 can monitor the connection status between the first connector 2 and the head-mounted display 100. When the second monitoring module 10 detects that the first connector 2 and the head-mounted display 100 are disconnected, it will immediately control the second power supply module 9 to stop supplying power to the second compensation module 5, preventing continued power supply from causing leakage in the first connector 2 and leading to serious safety problems, further ensuring the stable and safe operation of the entire data transmission line.

[0061] Similar to the function of the first monitoring module 7, the second monitoring module 10 can also monitor the connection abnormalities of the first connector 2, such as short circuits or poor contact. The second monitoring module 10 can quickly identify and issue alarm signals, and at the same time transmit the relevant abnormal information to the signal source 200 so that staff can conduct timely troubleshooting and repair.

[0062] For example, the second monitoring module 10 can determine the connection status between the first connector 2 and the head-up display 100 by monitoring the hot-plug detection signal status of the first connector 2. Specifically, when the first connector 2 is abnormally disconnected, that is, when the first connector 2 and the head-up display 100 are in a disconnected state, the second monitoring module 10 will detect that the hot-plug detection signal changes from a high level to a low level. To improve detection accuracy, the duration of the low level detection can be set, such as 3 seconds or 5 seconds. If the hot-plug detection signal remains low after 3 or 5 seconds, it is determined that the first connector 2 has been disconnected from the head-up display 100. Similarly, whether the hot-plug detection signal monitored by the second monitoring module 10 meets the high level requirement can be used to determine whether the first connector 2 has a connection abnormality. For example, if the hot-plug detection signal monitored by the second monitoring module 10 is higher than the low level but lower than the required high level, it is determined that the connection between the first connector 2 and the head-up display 100 is abnormal (e.g., poor contact), and further investigation and repair are required.

[0063] Under normal use, the second power supply module 9, the second monitoring module 10, and the second compensation module 5 are electrically connected. The second compensation module 5 can charge the second power supply module 9. When the power adapter is unplugged, the second power supply module 9 discharges to supply power to the second monitoring module 10 and the second compensation module 5.

[0064] The second power supply module 9 can specifically be a storage battery.

[0065] like Figure 1 , Figure 6 As shown, in some embodiments, the first connector 2 includes a second motherboard 21, which has a first interface, a second interface and a third interface, wherein the first interface and the end of the first sub-wire 112 away from the first second wire 121 are electrically connected, the second interface and the end of the second sub-wire 113 away from the second second wire 122 are electrically connected, and the third interface and the end of the third sub-wire 114 away from the third second wire 123 are electrically connected.

[0066] By setting up a second motherboard, the first interface of the second motherboard is electrically connected to the first sub-line 112, the second interface of the second motherboard is electrically connected to the second sub-line 113, and the third interface of the second motherboard is electrically connected to the third sub-line 114, thereby realizing the electrical connection between the first connector 2 and the first sub-line 112, the second sub-line 113, and the third sub-line 114.

[0067] It is understandable that when the first connector 2 is connected to the head-mounted display 100, the first interface, the second interface and the third interface are all electrically connected to the head-mounted display 100. The first interface can transmit the first data signal to the head-mounted display 100, the second interface can transmit the second data signal to the head-mounted display 100, and the third interface can transmit the third data signal to the head-mounted display 100.

[0068] like Figure 6 As shown, to further improve structural compactness, the second power supply module 9, the first second compensation module 51, the second second compensation module 52, the third second compensation module 53, and the second monitoring module 10 are all mounted on the second mainboard 21, and their specific arrangement is not limited. For example, the second power supply module 9, the first second compensation module 51, the second second compensation module 52, the third second compensation module 53, and the second monitoring module 10 can be arranged sequentially along the length or width of the second mainboard.

[0069] Specifically, the second motherboard has three third pins on one side, which are connected to the first sub-line 112, the second sub-line 113, and the third sub-line 114 respectively. The first second compensation module 51, the second second compensation module 52, and the third second compensation module 53 on the second motherboard are connected to the three third pins through multiple third conductive traces. The first interface, the second interface, and the third interface are connected to the first second compensation module 51, the second second compensation module 52, and the third second compensation module 53 through multiple fourth conductive traces. The first second compensation module 51, the second second compensation module 52, and the third second compensation module 53 transmit the compensated data signals to the first interface, the second interface, and the third interface respectively.

[0070] Specifically, the second monitoring module 10 is electrically connected to the first second connector 31, the second second connector 32, and the third second connector 33. The first monitoring module 7 can simultaneously monitor the connection status of the first second connector 31, the second second connector 32, the third second connector 33, and the signal source 200. When the first monitoring module 7 detects that any one of the first second connector 31, the second second connector 32, or the third second connector 33 is disconnected from the signal source 200, it can control the first power supply module 6 to disconnect from the first second compensation module 51, the second second compensation module 52, and the third second compensation module 53 to avoid the risk of leakage of the first connector 2.

[0071] like Figure 7 As shown, on the other hand, this application embodiment also provides an extended reality device, including a head-up display 100, a signal source 200 and a data transmission line of this application embodiment, wherein a first connector 2 of the data transmission line is connected to the head-up display 100, and at least one second connector 32 of the data transmission line is connected to the signal source 200.
