Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of intelligent electronic devices, and in particular to a signal transmission cable and intelligent glasses. BACKGROUND

[0002] The split type intelligent glasses need to obtain video data from other intelligent terminals, such as a mobile phone, when working. To ensure the smoothness and clarity of the picture presented by the intelligent glasses, the stability of data transmission needs to be considered.

[0003] In the related art, a USB 3.0 cable is usually used to connect the intelligent glasses and the mobile phone to establish large data transmission between the two. In order to reduce the loss of data in the transmission process, the current solution is basically to fix the signal transmission cable and the intelligent glasses body through structure to form an integrated structure, so as to reduce the loss of signal by the interface; and to reduce the cable length as much as possible to reduce the line impedance and reduce the degree of signal attenuation. However, this solution results in that the signal transmission cable is not very flexible to use, because its length and interface type cannot be adjusted. This causes great inconvenience to the user when using the intelligent glasses.

[0004] The above information disclosed in the background section is only used to enhance the understanding of the background of the present disclosure, and therefore it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0005] One object of the present disclosure is to improve the use flexibility of the signal transmission cable while reducing the impact on the stability of signal transmission.

[0006] To solve the above technical problems, the present disclosure adopts the following technical solutions:

[0007] According to one aspect of the present disclosure, the present disclosure provides a signal transmission cable, which comprises:

[0008] a cable body, a signal enhancement module being connected in series on the cable body; the signal enhancement module is used to enhance the signal transmitted on the cable body;

[0009] a first connection port provided at one end of the cable body, used to connect a first electronic device to input a signal;

[0010] a second connection port provided at the other end of the cable body relative to the first connection port; the second connection port is connected by a second electronic device; the signal input from the first connection port is enhanced by the signal enhancement module and then output from the second connection port to the second electronic device;

[0011] A third connecting port is connected to the cable body, and the third connecting port is connected to an external power supply. The power input from the third connecting port is output from the second connecting port to supply power to the second electronic device.

[0012] According to one aspect of the present disclosure, the present disclosure provides a signal transmission cable, which comprises:

[0013] A data transmission line, wherein a signal enhancement module is connected in series to the signal transmission line, and the signal enhancement module is used to enhance the signal transmitted on the data transmission line; one end of the data transmission line is connected to a first electronic device, and the other end is connected to a second electronic device;

[0014] A first power supply line, wherein one end of the first power supply line is connected to an external power supply, and the other end is connected to the second electronic device, so that the external power supply supplies power to the second electronic device.

[0015] According to one aspect of the present disclosure, the present disclosure provides a smart glasses, which comprises a frame body, a temple, a mainboard, an imaging lens and the signal transmission cable;

[0016] The imaging lens and the mainboard are installed in the frame body; the frame body or the temple is connected to the signal transmission cable, so that the mainboard receives signals through the signal transmission cable to control the imaging lens to work.

[0017] In the present disclosure, the signal transmission cable for transmitting signals to the second electronic device is set as a separate structure, so it does not need to be fixed integrally on the second electronic device; therefore, the user can select a signal transmission cable with appropriate length and interface type to connect the second electronic device and the first electronic device, thereby improving the convenience and flexibility of connecting the second electronic device with different types and positions of the first electronic device.

[0018] In addition, in order to reduce the influence on the stability of signal transmission, the present disclosure further provides a signal enhancement module and a third connecting port. By setting the signal enhancement module, the signal strength is improved during signal transmission, and the strength attenuation of the signal caused by line impedance, electromagnetic interference and the like is compensated. Therefore, even if the cable body is long, the probability of complete signal transmission can be improved, and the stability of signal transmission is improved.

[0019] By setting the third connecting port, an external power supply is used to supply power to the electronic device, and by separating the signal transmission port from the power supply port, signal input and power input are respectively completed by two different devices, thereby reducing the heat generation of the battery of the first electronic device, reducing the influence of the heat generation on the running speed of the CPU of the first electronic device, and further improving the stability of the signal transmission of the first electronic device.

[0020] In summary, by using the signal transmission cable in the present disclosure to transmit signals, the use flexibility of the signal transmission cable is improved while the influence on the stability of signal transmission is reduced.

[0035] The preferred embodiments of the present disclosure are further described in detail below with reference to the accompanying drawings of the present disclosure.

[0036] The present disclosure proposes a signal transmission cable 100 for transmitting signals between a first electronic device and a second electronic device, which can include data type signals and control type signals. The cable proposed by the present disclosure can improve the flexibility of use of the signal transmission cable 100 while reducing the impact on the stability of signal transmission.

[0037] The first electronic device and the second electronic device can be a mobile phone 300, a tablet computer, a notebook computer, smart glasses 200, etc. In the following embodiments, the first electronic device is taken as a mobile phone 300, and the second electronic device is taken as smart glasses 200.

[0038] It should be understood that the signal transmission cable 100 of the present disclosure is not limited to be applied to transmitting signals to smart glasses 200, and can be used in other types of electronic devices for data interaction and scenarios requiring stable transmission.

[0039] The smart glasses 200 can be 3D glasses, virtual reality (VR) glasses, augmented reality (AR) glasses, etc. The smart glasses 200 generally include a glasses support and an imaging lens 24 mounted on the glasses support. The imaging lens 24 is used to form an image or a video according to the received signals for the wearer to watch. The imaging lens 24 can be one or more, and the number of imaging lenses 24 can be designed according to different needs, which is not limited herein.

[0040] The glasses support of the smart glasses 200 is used to be worn on the head of the wearer, and the glasses support can be in a ring shape to hold the head, or can be in a style similar to optical glasses, including two legs 22 to be arranged on the ears of the wearer.

[0041] The smart glasses 200 have an interface for signal transmission with the mobile phone 300, and the interface can be located on the glasses support of the smart glasses 200. Illustratively, in order to make the interface hidden and not affect the appearance of the smart glasses 200, the interface can be arranged on the leg 22 of the smart glasses 200.

[0042] Please refer to Figure 1 , Figure 1 is a structural schematic view of a signal transmission cable 100 connected with a mobile phone 300 and smart glasses 200 according to an example.

[0043] In an embodiment, the signal transmission cable 100 comprises a cable body 10, a first connection port 30, a second connection port 40, and a third connection port 50. The cable body 10 is provided with a signal enhancement module 20 in series; the signal enhancement module 20 is used to enhance the signal transmitted on the cable body 10; the first connection port 30 is arranged at one end of the cable body 10 for inputting signal; the second connection port 40 is arranged at the other end of the cable body 10 relative to the first connection port 30; the signal input from the first connection port 30 is output from the second connection port 40 after being enhanced by the signal enhancement module 20 to the smart glasses 200; the third connection port 50 is arranged at one end of the cable body 10, and the third connection port 50 is connected with an external power supply 400; the power input from the third connection port 50 is output from the second connection port 40 for powering the smart glasses 200.

[0044] In the embodiment, the signal transmission cable 100 is mainly used to transmit data signal between the mobile phone 300 and the smart glasses 200. Since the smart glasses 200 needs a large amount of data in unit time when working, the signal transmission cable 100 needs to have a high bandwidth to match the high-speed transmission protocol for signal transmission. Illustratively, the signal transmission cable can be used to transmit USB3.0 signal, and accordingly, the signal transmission cable is a USB3.0 signal transmission cable.

[0045] When the mobile phone 300 is connected to the first connection port 30 and the smart glasses 200 is connected to the second connection port 40, the mobile phone 300 can transmit signal to the smart glasses 200 through the signal transmission cable 100. After receiving the signal, the smart glasses 200 generates corresponding image on the imaging lens 24 through a series of data processing and conversion.

[0046] The first connection port, the second connection port 40, and the third connection port 50 can be the same or different. When the signal transmission cable 100 is a USB cable, one of the first connection port 30, the second connection port 40, and the third connection port 50 can be a Type C interface, a Type A interface, etc.

[0047] In the embodiment, the signal transmission cable 100 is arranged as an independent structure, and does not need to be fixed on the smart glasses 200 integrally; therefore, the user can select a signal transmission cable with appropriate length and interface type to connect the smart glasses 200 and the mobile phone 300, thereby improving the convenience and flexibility of connecting the smart glasses 200 with different types and positions of mobile phones 300.

[0048] The signal transmission cable is set to be independent, thereby improving the flexibility of the signal transmission cable 100, and meanwhile, in order to reduce the influence on the signal transmission stability, the structure of the signal transmission cable 100 is further improved.

[0049] The reasons affecting the signal transmission stability are as follows. On the one hand, during the signal conduction along the data transmission line 101, the signal is attenuated due to the impedance of the data transmission line 101. The longer the data transmission line 101 is, the greater the signal attenuation is. When the signal attenuation is too large, the smart glasses 200 cannot recognize the signal, and the signal transmission is incomplete. On the other hand, when the mobile phone 300 sends data signals at a high speed, the mobile phone 300 also supplies power to the smart glasses 200. Both the data sending state and the power supply state cause the mobile phone 300 to generate a large amount of heat, and the continuously increasing heat causes the CPU of the mobile phone 300 to run slowly, thereby reducing the signal sending stability of the mobile phone 300.

[0050] Therefore, the signal transmission cable 100 provided in the present disclosure can improve the signal transmission stability and help reduce the problem of reduced signal sending stability caused by overheating of the mobile phone 300.

[0051] In the embodiment, the signal enhancement module 20 is connected in series on the cable body 10. The cable body 10 includes a plurality of electric wires with the same extension direction, and a plastic skin wrapped outside the electric wires. At least one of the electric wires is used for data transmission, which is referred to as the data transmission line 101. Therefore, when the mobile phone 300 outputs a signal, the signal is transmitted to the smart glasses 200 along the data transmission line 101. The signal enhancement module 20 is connected in series on the data transmission line 101.

[0052] In the present disclosure, the signal enhancement module 20 is connected in series on the signal transmission line, so as to improve the signal strength during signal conduction and compensate for the strength attenuation of the signal caused by the line impedance, electromagnetic interference and the like. Therefore, even if the cable body is long, the probability of complete signal transmission can be improved, and the signal transmission stability is improved.

[0053] Please refer to Figure 2 , Figure 2 is a circuit connection structure schematic diagram of the signal transmission cable 100 according to an example.

[0054] In an example, the data transmission line 101 in the cable body 10 for data transmission includes a signal transmission wire SSTX and a signal receiving wire SSRX in parallel; the signal enhancement module 20 includes a first signal enhancement circuit 201 and a second signal enhancement circuit 202; the first signal enhancement circuit 201 is connected in series with the signal transmission wire SSTX to enhance the signal transmitted by the signal transmission wire SSTX; and the second signal enhancement circuit 202 is connected in series with the signal receiving wire SSRX to enhance the signal transmitted by the signal receiving wire SSRX.

[0055] The signal transmission wire SSTX and the signal receiving wire SSRX are connected in parallel between the mobile phone 300 and the smart glasses 200. The signal transmission wire SSTX is used to transmit high-speed signals from the mobile phone 300 to the smart glasses 200, and the signal receiving wire SSRX is used to transmit high-speed signals from the smart glasses 200 to the mobile phone 300. Through the signal transmission wire SSTX and the signal receiving wire SSRX, the signal interaction between the mobile phone 300 and the smart glasses 200 is realized.

[0056] In an example, the first signal enhancement circuit 201 and the second signal enhancement circuit 202 (collectively referred to as a signal enhancement circuit) can be built by a hardware circuit, so that the power supply voltage of the signal enhancement circuit can be flexibly set without separately setting a voltage stabilizing chip for the signal enhancement circuit.

[0057] In another example, the signal enhancement circuit can also use a diverted signal enhancement chip. The signal enhancement chip can be understood as a signal switching driver. When transmitting a USB3.0 signal, the signal enhancement chip restores the transmitted data signal by using equalization to compensate for channel loss, and uses a high differential voltage to drive the data signal outward. Thus, the possible cable body length is expanded, and the entire signal transmission cable 100 is compatible with the USB3.0 signal.

[0058] Illustratively, when the signal enhancement chip is powered on, the signal enhancement chip has a sending end and a receiving end, the sending end is connected with the smart glasses 200, and the receiving end is connected with the mobile phone 300. The sending end of the signal enhancement chip regularly detects the presence of the smart glasses 200, and when the smart glasses 200 are detected, the receiving end is enabled to prepare for switching driving.

[0059] Further, when the signal enhancement chip is used, in order to improve the working stability of the signal enhancement chip, in the present embodiment, the signal enhancement module 20 further includes a linear voltage stabilizing chip 203; the signal enhancement chip has an electric energy input end; and the voltage stabilizing chip is electrically connected with the electric energy input end of the signal enhancement chip to supply power to the signal enhancement chip.

[0060] Illustratively, the linear voltage stabilizing chip 203 needs a working voltage of 3.3V, and the linear voltage stabilizing chip 203 can directly output a stable 3.3V voltage, thus through the setting of the linear voltage stabilizing chip 203, the power supply reliability and accuracy of the signal enhancement chip can be improved, so that the signal enhancement chip works in the best working interval.

[0061] As mentioned above, in the related art, when the signal transmission cable 100 is a USB cable, the mobile phone 300 transmits data to the smart glasses 200 and simultaneously supplies power to the smart glasses 200. Both the transmitting state and the power supply state can cause the mobile phone 300 to generate a large amount of heat, and the continuously increasing heat can cause the CPU of the mobile phone 300 to slow down, thereby reducing the signal transmission stability of the mobile phone 300.

[0062] In the embodiment, the signal transmission cable 100 is further provided with a third connecting port 50, which is arranged at one end of the cable body 10 and is used for connecting an external power supply 400. The power input from the third connecting port 50 is output from the second connecting port 40 and used for supplying power to the smart glasses 200.

[0063] Here, the external power supply 400 can be a battery or an electronic device with a power supply function, such as a mobile power supply. Therefore, when the external power supply 400 is connected to the third connecting port 50, the electronic device is powered by the external power supply 400, and the smart glasses 200 do not need to be powered by the mobile phone 300, thereby reducing the heat generated by the battery of the mobile phone 300 and reducing the influence of the heat on the running speed of the CPU of the mobile phone 300, thereby improving the signal transmission stability of the mobile phone 300. Therefore, the embodiment improves the signal reception stability of the smart glasses 200.

[0064] In addition, compared with the scheme of using the mobile phone 300 to supply power to the smart glasses 200, the present scheme uses the external power supply 400 to supply power to the smart glasses 200 due to the third connecting port 50, thereby reducing the power consumption of the mobile phone 300 and prolonging the working time of the mobile phone 300.

[0065] The embodiment separates the signal transmission port from the power supply port to realize that the signal input and the power supply input are completed by two different devices, thereby avoiding the situation that the mobile phone 300 needs to output high-speed data and output power at the same time, which causes a large amount of heat.

[0066] Further, in order to improve the convenience of the user, the signal transmission cable 100 can also obtain the power in the mobile phone 300 without the external power supply 400, so in an embodiment, the cable body 10 includes a power supply line, the two ends of the power supply line are respectively electrically connected to the first connection port 30 and the second connection port 40, so that the mobile phone 300 connected to the first connection port 30 can supply power to the smart glasses 200 through the power supply line. Therefore, when the mobile phone 300 and the smart glasses 200 are connected to the signal transmission cable 100 at the same time, the mobile phone 300 can transmit data and power to the smart glasses 200 at the same time.

[0067] Here, the power supply line connected between the third connection port 50 and the second connection port 40 can be referred to as the first power supply line 102, one end of the first power supply line 102 is connected to the external power supply 400, and the other end is connected to the smart glasses 200, so that the external power supply 400 supplies power to the smart glasses 200. Here, the power supply line connected between the first connection port 30 and the second connection port 40 can be referred to as the second power supply line 103.

[0068] When the mobile phone 300 transmits signals to the smart glasses 200 through the data transmission line 101, if the third connection port 50 is not connected to the external power supply 400, the mobile phone 300 transmits power to the smart glasses 200 through the second power supply line 103 to supply power to the smart glasses 200.

[0069] When the third connection port 50 is connected to the external power supply 400 at the same time, in order to better coordinate the power supply of the mobile phone 300 and the external power supply 400 to the smart glasses 200, in an embodiment, the signal transmission cable 100 further includes a switching circuit 60, the input end of the switching circuit 60 has two, respectively connected to the first connection port 30 and the third connection port 50, the output end of the switching circuit 60 is electrically connected to the second connection port 40; the switching circuit 60 is used to switch to the first connection port 30 and the second connection port to make the mobile phone 300 supply power to the smart glasses 200; or switch to the third connection port 50 and the second connection port 40 to make the external power supply 400 supply power to the smart glasses 200.

[0070] From the perspective of the wires in the cable body, the input end of the switching circuit 60 has two, respectively connected to the first power supply line 102 and the second power supply line 103, the output end of the switching circuit 60 is connected to the smart glasses 200, and the switching circuit 60 is used to switch the power supply of the smart glasses 200 by the mobile phone 300 connected to the first power supply line 102, or by the smart glasses 200 connected to the second power supply line 103.

[0071] In an example, the switching chip switches according to the comparison result of the voltage of the first power supply line 102 and the second power supply line 103. When the external power supply 400 is not connected to the third connection port 50, the voltage of the first power supply line 102 is 0; when the mobile phone 300 is connected to the first connection port 30, the OTG function of the mobile phone 300 can output a voltage value of 4.75V-5.25V to the second power supply line 103. At this time, the switching circuit 60 switches to make the first power supply line 102 connected to the second connection port 40, so that the mobile phone 300 supplies power to the smart glasses 200.

[0072] When the external power supply 400 is connected to the third connection port 50, the voltage on the first power supply line 102 is greater than the voltage on the second power supply line 103 at this time, and the switching circuit 60 switches to make the second power supply line 103 connected to the second connection port 40, so that the external power supply 400 supplies power to the smart glasses 200.

[0073] It should be noted that the output voltage value of the mobile phone 300 when connected to the first connection port 30 can be set so that the voltage value on the first power supply line 102 is less than the voltage on the second power supply line 103 when the external power supply 400 is connected to the third connection port 50, so that the switching circuit 60 can accurately switch according to the comparison result of the voltage of the first power supply line 102 and the second power supply line 103.

[0074] In an example, the switching circuit 60 can be centered on a single-pole double-throw switch and built by some discrete devices. In another example, the switching circuit 60 can use a dedicated switching chip.

[0075] Please continue to refer to Figure 1 As described above, the signal transmission cable 100 includes the switching circuit 60, and the signal enhancement module 20 is arranged on the cable body. The switching circuit 60 and the signal enhancement module 20 both have a certain volume. In order to better protect the two, the working safety is improved. Therefore, in an embodiment, the signal transmission cable further includes a receiving box 70 arranged on the cable body, and the signal enhancement module 20 and the switching circuit 60 are received in the receiving box 70.

[0076] The switching circuit 60 and the signal enhancement module 20 are illustratively arranged on a PCB (Printed Circuit Board) to form a PCBA (Printed Circuit Board Assembly). The PCBA is electrically connected to the cable body in the receiving box 70. Specifically, the cable body outside the receiving box 70 has a protective sheath, and the cable body inside the receiving box 70 can not have a protective sheath, so as to facilitate the connection of the switching circuit 60 and the signal enhancement module 20 to the wires in the cable body.

[0077] Meanwhile, the third connection port 50 can be arranged on the receiving box 70. The third connection port 50 can be connected to the external power supply 400 through another transmission line.

[0078] The present disclosure further provides an intelligent glasses 200, which comprises a frame body 21, a temple 22, a mainboard 23, an imaging lens 24 and the signal transmission cable 100 in the above embodiments; the imaging lens 24 and the mainboard 23 are installed in the frame body 21; the frame body 21 or the temple 22 is connected to the signal transmission cable 100, so that the mainboard 23 receives signals through the signal transmission cable 100 to control the working of the imaging lens 24.

[0079] It should be understood that the intelligent glasses 200 can also have optical components, display components, etc. The mainboard 23 is arranged in the imaging lens 24. The mainboard 23 is used to receive signals transmitted by the signal transmission cable 100, so as to control the working of the optical components, the imaging lens 24, etc. to display corresponding pictures.

[0080] Meanwhile, the imaging lens 24 can be powered by the power transmitted by the signal transmission cable 100 when working. Of course, the intelligent glasses 200 can also be configured with a battery power supply system. When the mobile phone 300 is connected through the signal transmission cable 100, the power transmitted by the signal transmission cable 100 can charge the battery of the intelligent glasses 200.

[0081] In an embodiment, the signal transmission cable 100 can be fixed on the intelligent glasses 200 in an integrated manner, or can be connected to the intelligent glasses 200 through an interface and a connector to realize plug-in connection. In this case, a connection connector needs to be reserved on the intelligent glasses 200.

[0082] In order to make the connection plug not affect the appearance of the smart glasses 200, in an embodiment, the temple 22 has a flexible circuit board 25 therein, which is electrically connected with the main board 23; the temple 22 has a connection interface for the second connection port 40 of the signal transmission cable 100, the connection interface is electrically connected with the flexible circuit board 25, the connection interface receives the signal transmitted by the signal transmission cable 100, and transmits the signal to the main board 23 through the flexible circuit board 25.

[0083] In the embodiment, the signal received by the smart glasses 200 needs to pass through the signal transmission cable 100, the second connection port 40, the flexible circuit board 25, and finally the main board 23. Therefore, the structure of the smart glasses 200 puts higher requirements on the signal heating integrity. The signal transmission cable 100 in the technical scheme of the present disclosure improves the signal strength in the signal conduction process by setting the signal enhancement module 20 to compensate for the strength attenuation of the signal caused by line impedance, electromagnetic interference, etc. Therefore, even in the case of a long cable body, the probability of complete signal transmission can be improved, and the stability of signal transmission is improved.

[0084] Moreover, the third connection port 50 for connecting the external power supply 400 is arranged in the technical scheme of the present disclosure, so that the external power supply 400 supplies power to the electronic device, and the smart glasses 200 do not need to be powered by the mobile phone 300, thereby reducing the heat generated by the battery of the mobile phone 300, reducing the influence of the heat generated on the running speed of the CPU of the mobile phone 300, and thereby improving the stability of the signal transmission of the mobile phone 300.
