The first electronic device and the second electronic device may be a mobile phone 300, a tablet computer, a notebook computer, smart glasses 200, and the like. In the following embodiments, the first electronic device is a mobile phone 300, and the second electronic device is a pair of smart glasses 200.

It should be understood that the signal transmission cable 100 of the present disclosure is not limited to be applied to transmitting signals to the smart glasses 200, and other types of electronic devices may be used in a scenario where data interaction is performed and stability of transmission is required.

The smart glasses 200 may be 3D glasses, virtual reality vr (virtual reality) glasses, mixed reality ar (augmented reality) glasses, and the like. The smart glasses 200 generally include a glasses frame and an imaging lens 24 mounted on the glasses frame. The imaging lens 24 is used to form an image or video from the received signals for viewing by the wearer. The number of the imaging lenses 24 may be one or more, and the number of the imaging lenses 24 may be designed accordingly according to different needs, and the number of the imaging lenses 24 is not limited herein.

The glasses frame of the smart glasses 200 is used for being worn on the head of a wearer, and the glasses frame may be in a ring shape to hoop the head, or may be in a style similar to optical glasses, and includes two glasses legs 22 to be erected on the ears of the wearer.

The smart glasses 200 have an interface for signal transmission with the mobile phone 300, and the interface may be located on a glasses holder of the smart glasses 200. Illustratively, the interface may be provided on the temple 22 of the smart glasses 200 in order to conceal the interface so as not to affect the appearance of the smart glasses 200.

Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating a signal transmission cable 100 connected to a mobile phone 300 and smart glasses 200 according to an example.

In one embodiment, the signal transmission cable 100 includes 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 connected with a signal enhancement module 20 in series; the signal enhancement module 20 is used for enhancing the signal transmitted on the cable body 10; the first connection port 30 is arranged at one end of the cable body 10 and used for inputting signals; the second connection port 40 is provided at the other end of the cable body 10 opposite to the first connection port 30; after the signal input from the first connection port 30 is enhanced by the signal enhancement module 20, the signal is output from the second connection port 40 to the smart glasses 200; the third connection port 50 is connected to the cable body 10, the third connection port 50 is connected to an external power source 400, and the electric energy input from the third connection port 50 is output from the second connection port 40 to supply power to the smart glasses 200.

In the embodiment, the signal transmission cable 100 mainly transmits data signals between the mobile phone 300 and the smart glasses 200, and since the smart glasses 200 require a large amount of data in a unit time when operating, the signal transmission cable 100 needs to have a high bandwidth to cooperate with a high-speed transmission protocol to transmit signals. Illustratively, the signal transmission cable may be a signal transmission cable for transmitting USB3.0 signals, and correspondingly, the signal transmission cable is a signal transmission cable for USB 3.0.

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

Here, the first connection port, the second connection port 40, and the third connection port 50 may be the same or different. When the signal transmission cable 100 may be a kind of USB cable, it may be a Type C interface, a Type a interface, or the like for one of the first connection port 30, the second connection port 40, and the third connection port 50.

In this embodiment, the signal transmission cable 100 is an independent structural member, and does not need to be integrally fixed on the smart glasses 200; therefore, the user can select a signal transmission cable with a suitable length and a suitable interface type to connect the smart glasses 200 and the mobile phone 300, thereby improving convenience and flexibility in connecting the smart glasses 200 with different types and different positions of the mobile phone 300.

After the signal transmission cable is independently arranged, the flexibility of use of the signal transmission cable 100 is improved, and meanwhile, in order to reduce the influence on the signal transmission stability, the structure of the signal transmission cable 100 is further improved in the present embodiment.

The reason for the influence on the stability of signal transmission is, on one hand, that the signal is attenuated due to the impedance of the data transmission line 101 during the signal transmission along the data transmission line 101. The longer the data transmission line 101, the greater the degree of signal attenuation. When the signal attenuation is too large to be recognized by the smart glasses 200, the signal transmission may be incomplete. On the other hand, when the mobile phone 300 transmits a data signal to the outside at a high speed, the smart glasses 200 are also powered. Both the data transmission state and the power supply state can generate larger heat for the mobile phone 300, and the continuously increased heat can cause the running speed of the CPU of the mobile phone 300 to be reduced, thereby causing the signal transmission stability of the mobile phone 300 to be reduced.

Based on this, the signal transmission cable 100 proposed by the present disclosure can simultaneously improve the stability of the transmission signal and help alleviate the problem of the reduction of the signal transmission stability caused by the overheating of the mobile phone 300.

In the present embodiment, a signal amplification module 20 is connected in series to the cable body 10. Illustratively, the cable body 10 includes a plurality of turns of electric wires extending in the same direction, and a plastic sheath covering the electric wires. At least one of these wires is used for data transmission and is referred to herein as a data transmission line 101. Therefore, when the mobile phone 300 outputs a signal, the signal is transmitted along the data transmission line 101 toward the smart glasses 200. The signal enhancement module 20 is connected in series to the data transmission line 101.

In the present disclosure, the signal enhancement module 20 is connected in series to the signal transmission line, so as to improve the signal strength and compensate the strength attenuation of the signal caused by line impedance, electromagnetic interference and the like in the signal transmission process; therefore, even under the condition that the cable main body is long, the probability of completely transmitting signals can be improved, and the stability of signal transmission is improved.

Referring to fig. 2, fig. 2 is a schematic circuit connection structure diagram of a signal transmission cable 100 according to an example.

In one example, the data transmission line 101 for data transmission in the cable body 10 includes a signal transmission wire SSTX and a signal reception wire SSRX connected in parallel; the signal enhancement module 20 comprises a first signal enhancement circuit 201 and a second signal enhancement circuit 202; the first signal enhancement circuit 201 is connected in series to the signal transmission wire SSTX to enhance the signal transmitted by the signal transmission wire SSTX; the second signal enhancement short circuit is connected in series to the signal reception conductor SSRX to enhance the signal transmitted on the signal reception conductor SSRX.

The signal transmission wire SSTX and the signal reception wire SSRX are connected in parallel between the cellular phone 300 and the smart glasses 200. The signal transmitting wire SSTX is used for transmitting a high-speed signal from the mobile phone 300 to the smart glasses 200, and the signal receiving wire SSRX is used for transmitting a high-speed signal from the smart glasses 200 to the mobile phone 300. Through the arrangement of the signal transmitting wire SSTX and the signal receiving wire SSRX, the signal interaction between the mobile phone 300 and the smart glasses 200 is realized.

In an example, the first signal enhancement circuit 201 and the second signal enhancement circuit 202 (collectively referred to as signal enhancement circuits) may be implemented by hardware circuit building, so that the supply voltage of the signal enhancement circuits may be flexibly set without separately setting a voltage stabilization chip for supplying power to the signal enhancement circuits.

In another example, the signal enhancement circuit may also employ a re-used signal enhancement chip. The signal enhancement chip may be understood as a signal transfer driver. When transmitting USB3.0 signals. The signal enhancement chip recovers the transmitted data signal by employing equalization that compensates for channel loss and drives the data signal outward using a high differential voltage. Thereby, the possible cable body length is extended and the entire signal transmission cable 100 is made compatible with USB3.0 signals.

Illustratively, after 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 can periodically detect the existence of the intelligent glasses 200, and after the intelligent glasses 200 are detected, the receiving end is started to prepare for the switching drive.

Further, when a signal enhancement chip is adopted, in order to improve the working stability of the signal enhancement chip, in this embodiment, the signal enhancement module 20 further includes a linear voltage stabilization chip 203; the signal enhancement chip is provided with an electric energy input end; the voltage stabilizing chip is electrically connected with the electric energy input end of the signal enhancement chip to supply power for the signal enhancement chip.

Illustratively, the working voltage required by the linear regulator chip 203 is 3.3V, and the linear regulator chip 203 can directly output a stable 3.3V voltage, so that the power supply reliability and accuracy of the signal enhancement chip can be improved through the arrangement of the linear regulator chip 203, so that the signal enhancement chip works in the optimal working interval.

As described above, in the related art, when the signal transmission cable 100 is a USB cable, the mobile phone 300 supplies power to the smart glasses 200 while transmitting data to the smart glasses 200. According to the sending state and the power supply state, the mobile phone 300 generates a large amount of heat, and the continuously increased heat can cause the running speed of the CPU of the mobile phone 300 to be reduced, thereby causing the stability of signal sending of the mobile phone 300 to be reduced.

In this embodiment, the signal transmission cable 100 further includes a third connection port 50, the third connection port 50 is disposed at one end of the cable body 10, the third connection port 50 is connected to an external power source 400, and the electric energy input from the third connection port 50 is output from the second connection port 40 to supply power to the smart glasses 200.

Here, the external power source 400 may be a battery, or may be an electronic device having a power supply function, such as a mobile power source. Therefore, when the external power source 400 is connected to the third connection port 50, the external power source 400 supplies power to the electronic device, and the smart glasses 200 do not need to be supplied with power through the mobile phone 300, so that the heat generation amount of the battery of the mobile phone 300 is reduced, the influence degree of the heat generation amount on the operating speed of the CPU of the mobile phone 300 is reduced, and the stability of the mobile phone 300 for sending signals is further improved, and therefore, the stability of the smart glasses 200 for receiving signals is improved.

In addition, compared with the scheme of using the mobile phone 300 to supply power to the smart glasses 200, the external power supply 400 can be used to supply power to the smart glasses 200 due to the arrangement of the third connection port 50, so that the power consumption of the mobile phone 300 is reduced, and the working time of the mobile phone 300 is prolonged.

In the embodiment, the signal transmission port and the power supply port are separated, so that the signal input and the power supply input are respectively completed by two different devices, and the situation that the heat productivity is large due to the fact that the mobile phone 300 needs to output high-speed data and output electric energy is avoided.

Further, in order to improve the convenience of the user, so that the power in the mobile phone 300 can be obtained through the signal transmission cable 100 even without the external power source 400, in an embodiment, the cable body 10 includes a power supply line, and 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 supplies power to the smart glasses 200 through the power supply line. Therefore, when the mobile phone 300 and the smart glasses 200 are simultaneously connected with the signal transmission cable 100, the mobile phone 300 can simultaneously transmit data and power to the smart glasses 200.

Here, the power supply line connected between the third connection port 50 and the second connection port 40 may be referred to as a first power supply line 102, one end of the first power supply line 102 is connected to an 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. The second power supply line 103 may be referred to as a power supply line connected between the first connection port 30 and the second connection port 40.

When the mobile phone 300 transmits a signal to the smart glasses 200 through the data transmission line 101, if the third connection port 50 is not connected to the external power source 400, the mobile phone 300 transmits electric energy to the smart glasses 200 through the second power supply line 103 to supply power to the smart glasses 200.

In order to better coordinate the mobile phone 300 and the external power source 400 to supply power to the smart glasses 200 when the external power source 400 is simultaneously connected to the third connection port 50, in an embodiment, the signal transmission cable 100 further includes two switching circuits 60, two input ends of the switching circuits 60 are respectively electrically connected to the first connection port 30 and the third connection port 50, and an output end of the switching circuit 60 is electrically connected to the second connection port 40; the switching circuit 60 is used for switching to the first connection port 30 to be electrically connected with the second connection port, so that the mobile phone 300 supplies power to the smart glasses 200; or the third connection port 50 is switched to be electrically connected with the second connection port 40, so that the external power source 400 supplies power to the smart glasses 200.

From the perspective of the electric wire in the cable body, there are two input ends of the switching circuit 60, which are electrically connected to the first power supply line 102 and the second power supply line 103, respectively, and an output end of the switching circuit 60 is connected to the smart glasses 200, and the switching circuit 60 is configured to switch between supplying power to the smart glasses 200 from the mobile phone 300 connected to the first power supply line 102 or supplying power to the smart glasses 200 connected to the second power supply line 103.

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

When the external power source 400 is connected to the third connection port 50, the voltage on the first power supply line 102 is higher than the voltage on the second power supply line 103, and the switching circuit 60 switches to connect the second power supply line 103 and the second connection port 40, so that the external power source 400 supplies power to the smart glasses 200.

It should be noted that the output voltage value of the mobile phone 300 when connected to the first connection port 30 may be set so that the voltage value on the first power supply line 102 is smaller 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 perform switching according to the comparison result of the voltages of the first power supply line 102 and the second power supply line 103.

In one example, the switching circuit 60 may be a hardware circuit built with discrete devices centered on a single pole double throw switch. In another example, the switching circuit 60 may employ a dedicated switching chip.

Please continue to refer to fig. 1. As mentioned above, the signal transmission cable 100 includes the switching circuit 60, and the signal enhancement module 20 is disposed on the cable main body, and both the switching circuit 60 and the signal enhancement module 20 have a certain volume. The two are protected better, so that the working safety of the two is improved. Therefore, in an embodiment, the signal transmission cable further includes a housing box 70 disposed on the cable body, and the signal enhancement module 20 and the switching circuit 60 are housed in the housing box 70.

Illustratively, the switching Circuit 60 and the signal enhancement module 20 are commonly disposed on a pcb (printed Circuit Board) Board to form a pcba (printed Circuit Board assembly). The PCBA is electrically connected to the cable main body in the housing box 70. Specifically, the outer layer of the cable body located outside the accommodating box 70 has a protective skin, and the cable body located inside the accommodating box 70 may not have a protective skin, so that the switching circuit 60 and the signal enhancement module 20 can be connected with the electric wires inside the cable body.

Meanwhile, the third connection port 50 may be provided on the receiving case 70. The third connection port 50 may be connected to the external power source 400 through another transmission line.

The present disclosure further provides a pair of smart glasses 200, wherein the smart glasses 200 include a frame main body 21, a temple 22, a main board 23, an imaging lens 24, and the signal transmission cable 100 in the above embodiments; the imaging lens 24 and the main plate 23 are mounted in the frame body 21; the frame main body 21 or the temple 22 is connected to the signal transmission cable 100, so that the main board 23 receives a signal through the signal transmission cable 100 to control the imaging lens 24 to operate.

It should be understood that optical components, display components, etc. may also be present within the smart eyewear 200. The imaging optics 24 have a main plate 23 therein. The main board 23 is used for receiving the signal transmitted by the signal transmission cable 100, so as to control the operation of the optical components, the imaging lens 24 and the like, and display the corresponding pictures.

At the same time, the imaging lens 24 may be powered by the power transmitted by the signal transmission cable 100 during operation. Of course, the smart glasses 200 themselves may also be configured with a battery powered system. When the mobile phone 300 is connected through the signal transmission cable 100, the battery of the smart glasses 200 may be charged by the power transmitted through the signal transmission cable 100.

In an embodiment, the signal transmission cable 100 may be integrally fixed to the smart glasses 200, or may be connected to the smart glasses 200 through an interface and a connector. In this case, a connection joint needs to be reserved on the smart glasses 200.

In order that the connecting plug does not affect the appearance of the smart glasses 200, in one embodiment, the temple 22 has a flexible circuit board 25 therein, and the flexible circuit board 25 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 to the flexible circuit board 25, and 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.

In this embodiment, the signal received by the smart glasses 200 is transmitted to the main board 23 through the signal transmission cable 100, the second connection port 40, the flexible circuit board 25, and finally. Thus, this configuration of the smart eyewear 200 places higher demands on signal heating integrity. In the signal transmission cable 100 in the technical scheme of the present disclosure, on one hand, the signal enhancement module 20 is arranged to improve the signal intensity and compensate the intensity attenuation of the signal caused by the line impedance, the electromagnetic interference and other conditions in the signal transmission process; therefore, even under the condition that the cable main body is long, the probability of completely transmitting signals can be improved, and the stability of signal transmission is improved.

In addition, according to the scheme of the present disclosure, the third connection port 50 for connecting the external power supply 400 is provided, so that the external power supply 400 supplies power to the electronic device, and the smart glasses 200 do not need to be supplied with power through the mobile phone 300, thereby reducing the heat generation amount of the battery of the mobile phone 300, reducing the influence degree of the heat generation amount on the operating speed of the CPU of the mobile phone 300, and further improving the stability of the signal transmission of the mobile phone 300.

In summary, by using the signal transmission cable 100 in the present disclosure to transmit signals, the stability of the smart glasses 200 in receiving signals is improved.
