[0053] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0055] The terms "first" and "second" in the specification and claims of this utility model are used to distinguish different objects, rather than to describe a specific order of objects. For example, the terms "first camera" and "second camera" are used to distinguish different cameras, rather than to describe a specific order of cameras.

[0056] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner. In addition, in the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality" refers to two or more.

[0057] The solution provided by the present invention can be used in application scenarios where electronic devices are used for USB signal transmission in daily production or daily life. For ease of understanding, the application scenarios involved in the embodiments of the present invention are briefly introduced below.

[0058] With the rapid development of science and technology, various electronic devices have appeared in people's daily lives. People can generate various data in the process of using electronic devices. The data they want to transmit can be shared through various data cables, communication connections, etc.

[0059] For example, common electronic devices include mobile phones, tablets, smart glasses, smart watches, MP3 players (Moving Picture Experts Group Audio Layer III), MP4 (Moving Picture Experts Group Audio Layer IV) players, and many other devices. These devices can establish wired connections with other devices such as desktop computers through data cables (commonly also called USB cables) to transmit the desired data.

[0060] Generally speaking, if different electronic devices want to transmit USB data, most of them interact with external devices through data cables. Figure 1 , which shows a schematic diagram of a scenario in which a wired connection is established between electronic devices for data transmission according to an exemplary embodiment of the present utility model. Figure 1 As shown, it includes a first electronic device 101, a data cable 102, and a second electronic device 103. The first electronic device 101 and the second electronic device 103 can establish a wired connection via the data cable 102. When USB data is to be transmitted, the first electronic device 101 transmits a USB signal carrying the USB data of the first electronic device 101 and transmits it to the second electronic device 103 via the data cable 102. Of course, the second electronic device 103 can also send a USB signal to the first electronic device 101 via the data cable 102, carrying the USB data of the second electronic device 103, thereby realizing mutual transmission between the two electronic devices.

[0061] In the above Figure 1 In the present invention, when an electronic device establishes a communication connection with other external electronic devices, data transmission and reception can be achieved through the connection of data cables through the interface provided by the electronic device. Therefore, in the actual design of electronic devices, it is necessary for the electronic device to provide a variety of interfaces (at least including USB interfaces) to complete data transmission by connecting corresponding data cables. Therefore, common USB interfaces all require the use of data cables, and it is necessary to design a USB interface on the physical structure of the electronic device, which will occupy a certain amount of space, causing space compression and affecting the space utilization of the electronic device.

[0062] To facilitate the transmission of USB signals between electronic devices, reduce the space occupied by USB interfaces in electronic devices, and improve the space utilization of electronic devices, the utility model provides a wireless USB signal transmission device that uses wireless technology to achieve wireless USB signal transmission between electronic devices. This eliminates the need for a dedicated USB interface in the physical structure, thus achieving a wireless USB interface design.

[0063] Please refer to Figure 2 , which shows a schematic structural diagram of a wireless USB signal transmission device provided by an exemplary embodiment of the present utility model. Figure 2 As shown, the wireless USB signal transmission device 200 includes: a wireless USB module 201, and a wireless coupling module 202;

[0064] exist Figure 2 In the embodiment, the wireless USB module 201 is electrically connected to the wireless coupling module 202 .

[0065] Among them, the wireless coupling module 202 is used to couple with the wireless coupling module of other devices to establish a wireless communication connection with other devices; the wireless USB module 201 is used to generate and transmit wireless USB signals through the wireless coupling module, or receive wireless USB signals transmitted by other devices through the wireless coupling module.

[0066] That is, the wireless coupling module 202 provided in this solution can couple with the wireless coupling module of another device to establish a wireless communication connection. The wireless USB module 201 can generate the USB signal to be transmitted and transmit the wireless USB signal via the wireless coupling module and the wireless communication connection. Alternatively, if the wireless coupling module 202 and the wireless communication connection receive a wireless USB signal transmitted by another device, the wireless USB module 201 can also receive wireless USB signals transmitted by the other device. In other words, the wireless coupling module 202 can transmit the USB signal generated by the electronic device to the other device with which the wireless communication connection is established, and can also receive the USB signal transmitted by the other device via the wireless coupling module 202, thereby enabling the transmission of USB signals between the electronic device and the other device.

[0067] Optionally, the wireless coupling module of other devices and the wireless coupling module of the wireless USB signal transmission device in this solution are paired. In actual use, the two can be coupled to establish a wireless communication connection. The wireless coupling module is equivalent to an antenna for sending and receiving USB signals, and controls the transmission of USB signals through the baseband chip.

[0068] In summary, the wireless USB signal transmission device provided by the present invention includes: a wireless USB module and a wireless coupling module; the wireless USB module is electrically connected to the wireless coupling module; the wireless coupling module is used to couple with the wireless coupling module of another device to establish a wireless communication connection with the other device; and the wireless USB module is used to generate and transmit wireless USB signals via the wireless coupling module, or to receive wireless USB signals transmitted by the other device via the wireless coupling module. The wireless coupling module couples with the wireless coupling module of the other device to establish a wireless communication connection. When the wireless USB module needs to transmit a wireless USB signal, it transmits it via the wireless coupling module, eliminating the need for a data cable, allowing the wireless coupling module to perform the coupling connection. This also eliminates the need to design a USB interface within the electronic device, thereby improving the space utilization of the electronic device.

[0069] In a possible implementation, the wireless coupling module is composed of a dual-structure coupling device, and coupling is performed through the dual-structure coupling device to establish a communication connection for a wireless USB signal.

[0070] Please refer to Figure 3 , which shows a schematic structural diagram of a wireless USB signal transmission device provided by an exemplary embodiment of the present utility model. Figure 3 As shown, the wireless USB signal transmission device 300 includes: a baseband chip 301, a wireless USB module 302, and a wireless coupling module 303. Figure 3 In the embodiment, the baseband chip 301 includes a wireless USB module 302 , and the wireless USB module 302 is electrically connected to the wireless coupling module 303 .

[0071] The wireless coupling module 303 is configured to couple with the wireless coupling module of another device to establish a wireless communication connection with the other device. The baseband chip 301 is configured to control the wireless USB module 302 to generate and transmit wireless USB signals via the wireless coupling module and the wireless communication connection, or to control the wireless USB module 302 to receive wireless USB signals transmitted by another device via the wireless coupling module and the wireless communication connection. Optionally, the wireless USB module 302 may be part of the baseband chip 301 or independent. The generation or reception of wireless USB signals by the wireless USB module may be controlled by the baseband chip 301 or independently. The specific control method may be determined by the developer in the actual application. This example uses the baseband chip 301 including the wireless USB module 302 as an example. In actual applications, the steps performed by the baseband chip may also be performed by the wireless USB module itself, and this is not a limitation here.

[0072] Optionally, the wireless coupling module 303 is composed of a dual-structure coupling device. Figure 3In the embodiment, the dual-structure coupling device includes a first device 303a and a second device 303b. The first device 303a is connected to the wireless USB module 302 to form a positive channel, and the second device 303b is connected to the wireless USB module 302 to form a negative channel.

[0073] The wireless USB module 302 can transmit wireless USB signals to the wireless coupling module 303 via the positive and negative channels, and transmit wireless USB signals to other devices via wireless communication connections. When receiving wireless USB signals transmitted by other devices via wireless communication connections, the wireless USB module 302 can also receive wireless USB signals transmitted by other devices via the positive and negative channels.

[0074] For example, in the above Figure 3 In the example, the wireless USB signal generated by the wireless USB module includes communication data. The first device 303a and the second device 303b are connected to the D+ and D- output terminals of the wireless USB module 302, respectively, thereby transmitting the wireless USB signal to the wireless coupling module 303 through the positive and negative channels, and then transmitting it to other devices. Of course, the first device 303a and the second device 303b can also receive wireless USB signals sent by other devices and transmit them to the wireless USB module 302 through the D+ and D- output terminals, thus achieving the reception function.

[0075] Optionally, the dual-structure coupling device is any one of a capacitive coupling pad and a coupling resonator.

[0076] Please refer to Figure 4 , which shows a schematic structural diagram of a wireless USB signal transmission device including a capacitive coupling pad in an exemplary embodiment of the present invention. Figure 4 As shown, it includes a baseband chip 401, a wireless USB module 402, a first capacitive coupling pad 403, and a second capacitive coupling pad 404. Figure 4 In the figure, the D+ output terminal of the wireless USB module 402 is electrically connected to the first capacitive coupling pad 403, and the D- output terminal of the wireless USB module 402 is electrically connected to the second capacitive coupling pad 404. The first capacitive coupling pad 403 and the second capacitive coupling pad 404 can be a disc-shaped structure or a regular polygonal structure (such as a square pad). Figure 4 The disc-shaped structure is used as an example.

[0077] The wireless USB signal transmission device provided by the utility model can be coupled with the capacitive coupling pads of other devices through its own capacitive coupling pads to Figure 4For example, if two electronic devices are both equipped with the above-mentioned wireless USB signal transmission device, when the two electronic devices (electronic device 1 and electronic device 2) need to communicate wireless USB signals, they can first couple through their respective capacitive coupling pads, that is, the first capacitive coupling pad of electronic device 1 and the first capacitive coupling pad of electronic device 2, and the second capacitive coupling pad of electronic device 1 and the second capacitive coupling pad of electronic device 2, so that the two devices establish a wireless communication connection. After electronic device 1 generates a wireless USB signal through its own wireless USB module, it transmits the wireless USB signal to the first capacitive coupling pad and the second capacitive coupling pad through the positive channel and the negative channel. The first capacitive coupling pad transmits the signal to the first capacitive coupling pad of electronic device 2, and the second capacitive coupling pad transmits the signal to the second capacitive coupling pad of electronic device 2, thereby transmitting the wireless USB signal to electronic device 2. Conversely, if electronic device 2 needs to send a wireless USB signal to electronic device 1, the same method is used. The wireless USB signal sent by electronic device 2 will be received in electronic device 1 through the positive channel and the negative channel.

[0078] Please refer to Figure 5 , which shows a schematic structural diagram of a wireless USB signal transmission device including a coupling resonator according to an exemplary embodiment of the present invention. Figure 5 As shown, it includes a baseband chip 501, a wireless USB module 502, a first coupling resonator 503, and a second coupling resonator 504. Figure 5 In the embodiment, the D+ output terminal of the wireless USB module 502 is electrically connected to the first coupling resonator 503, and the D- output terminal of the wireless USB module 502 is electrically connected to the second coupling resonator 504. Figure 5 In the example, the first coupled resonator 503 and the second coupled resonator 504 are C-shaped structures. In practical applications, the first coupled resonator 503 and the second coupled resonator 504 may also be Z-shaped structures, wave-shaped structures, etc., which will not be described in detail here.

[0079] Optionally, in order to reduce the interference of USB signal transmission, Figure 5 In the embodiment, the opening directions of the first coupling resonator 503 and the second coupling resonator 504 are the same, both facing Figure 5 Of course, they can also be set to face the left, and this solution is not limited to this. Figure 5 The principle of wireless USB signal transmission through coupling resonators is similar to that of transmission through capacitive coupling pads. Both devices are coupled through their own dual-structure coupling devices. Please refer to the above Figure 4 The relevant transmission content will not be repeated here.

[0080] Optionally, the wireless USB module 302 needs to transmit and receive wireless USB signals, and thus needs to include a signal generating unit and a signal receiving unit.

[0081] In one possible implementation, the wireless USB module includes a signal generating unit and a signal receiving unit, and the signal generating unit and the signal receiving unit share a wireless coupling module; the wireless USB module is further configured to control the signal generating unit in the wireless USB module to be electrically connected to the wireless coupling module, so that the wireless USB signal generated by the signal generating unit is transmitted to other devices via the wireless coupling module; the wireless USB module is further configured to control the signal receiving unit in the wireless USB module to be electrically connected to the wireless coupling module, so that the wireless USB module receives the wireless USB signal transmitted by other devices via the wireless coupling module.

[0082] That is, in the wireless USB signal transmission device provided by this solution, the wireless USB module 302 can provide the function of sending and receiving wireless USB signals, and the signal generating unit and the signal receiving unit can share the same wireless coupling module. The wireless USB module 302 itself can control the operation of the signal generating unit or the signal receiving unit. Of course, the baseband chip 301 can also control the operation of the signal generating unit or the signal receiving unit. When the baseband chip 301 is required to control the operation of the signal generating unit, the baseband chip 301 controls the signal generating unit in the wireless USB module to electrically connect with the wireless coupling module, so that the wireless USB signal generated by the wireless USB module is transmitted to other devices via the wireless coupling module and the wireless communication connection, thereby realizing the wireless USB signal transmission function. When the baseband chip 301 is required to control the operation of the signal receiving unit, the baseband chip 301 controls the signal receiving unit in the wireless USB module to electrically connect with the wireless coupling module, so that the wireless USB module receives the wireless USB signal transmitted by other devices via the wireless coupling module and the wireless communication connection, thereby realizing the wireless USB signal reception function.

[0083] Optionally, to account for signal attenuation during wireless USB signal transmission, the transmitted wireless USB signal needs to be amplified in advance. In one possible implementation, the signal generation unit also includes a first amplifying device; the signal generation unit is electrically connected to the wireless coupling module via the first amplifying device; the first amplifying device is configured to amplify the wireless USB signal generated by the signal generation unit and transmitted to the wireless coupling module, so that the amplified wireless USB signal can be transmitted to other devices via the wireless coupling module and a wireless communication connection. In other words, after the signal generation unit generates the wireless USB signal, it needs to be amplified to facilitate transmission of the wireless USB signal via the wireless coupling module and improve the accuracy of the transmitted wireless USB signal.

[0084] Similarly, given the attenuation of received wireless USB signals, amplification is also required. In one possible implementation, the signal receiving unit further includes a second amplifying device, which is electrically connected to the wireless coupling module via the second amplifying device. The second amplifying device is configured to amplify wireless USB signals transmitted by other devices and received by the wireless coupling module. In other words, wireless USB signals attenuate during transmission. Amplification of the wireless USB signals received by the wireless coupling module within the signal receiving unit facilitates demodulation of the wireless USB signals and improves the accuracy of received wireless USB signals.

[0085] In one possible implementation, the first amplifying device provided above includes a first amplifying unit and a second amplifying unit; the input end of the first amplifying unit is connected to the positive output end of the signal generating unit, and the output end of the first amplifying unit is also connected to the positive pole of the wireless coupling module to form a positive transmission channel; the input end of the second amplifying unit is connected to the negative output end of the signal generating unit, and the output end of the second amplifying unit is also connected to the negative pole of the wireless coupling module to form a negative transmission channel; the first amplifying device amplifies the wireless USB signal to be transmitted generated by the signal generating unit through the positive transmission channel and the negative transmission channel.

[0086] Similarly, similar to the composition structure of the first amplifying device, the second amplifying device provided above includes a third amplifying unit and a fourth amplifying unit; the output end of the third amplifying unit is connected to the positive input end of the signal receiving unit, and the input end of the third amplifying unit is also connected to the positive pole of the wireless coupling module to form a positive receiving channel; the output end of the fourth amplifying unit is connected to the negative input end of the signal generating unit, and the input end of the fourth amplifying unit is also connected to the negative pole of the wireless coupling module to form a negative receiving channel; the first amplifying device amplifies the wireless USB signal transmitted by other devices through the positive receiving channel and the negative receiving channel.

[0087] In order to better illustrate the structure of the wireless USB module 302, the following takes the wireless USB module 302 as an example to realize the function of wireless USB signal transmission alone. Figure 6 , which shows a schematic structural diagram of a wireless USB module in a wireless USB signal transmission device according to an exemplary embodiment of the present invention. Figure 6 As shown, it includes a signal generating unit 601, a first amplifying device 602, a first amplifying unit 602a, a second amplifying unit 602b, a wireless coupling module 603, a first device 603a, and a second device 603b. Figure 6 In the example, the wireless USB signal to be transmitted is generated by the signal generating unit 601. Before being transmitted to the wireless coupling module 603 via D+D-, the signal outputted from the positive output terminal of the signal generating unit enters the input terminal of the first amplifying unit 602a, amplified by the first amplifying unit 602a, and transmitted to the wireless coupling module. The signal outputted from the negative output terminal of the signal generating unit enters the input terminal of the second amplifying unit 602b, amplified by the second amplifying unit 602b, and transmitted to the wireless coupling module. The positive transmission channel is equivalent to the signal channel from the positive output terminal of the signal generating unit to the first device 603a, and the negative transmission channel is equivalent to the signal channel from the negative output terminal of the signal generating unit to the second device 603b. Figure 6 The wireless coupling device can be the above Figure 4 and Figure 5 The structure shown is not described here in detail.

[0088] Taking the wireless USB module 302 as an example to realize the wireless USB signal receiving function alone, please refer to Figure 7 , which shows a schematic structural diagram of a wireless USB module in a wireless USB signal transmission device according to an exemplary embodiment of the present invention. Figure 7 As shown, it includes a signal receiving unit 701, a second amplifying device 702, a third amplifying unit 702a, a fourth amplifying unit 702b, a wireless coupling module 703, a first device 703a, and a second device 703b. Figure 7In the wireless USB signal received by the first device 703a and the second device 703b of the wireless coupling module 703, after entering, before reaching the signal receiving unit 701, the wireless USB signal is amplified by the second amplifier device connected with D+D-. Among them, the signal received by the first device 703a enters the input end of the third amplifier unit 702a, is amplified by the third amplifier unit 702a, and is transmitted to the positive input end of the signal receiving unit; the signal received by the second device 703b enters the input end of the fourth amplifier unit 702b, is amplified by the fourth amplifier unit 702b, and is transmitted to the negative input end of the signal receiving unit. The positive receiving channel is equivalent to the signal channel between the first device 703a and the positive input end of the signal receiving unit, and the negative receiving channel is equivalent to the signal channel between the second device 703b and the negative input end of the signal receiving unit. Among them, Figure 7 The wireless coupling device can be the above Figure 4 and Figure 5 The structure shown is not described here in detail.

[0089] above Figure 6 and Figure 7 This is an example of independently providing their own signal transmission and signal receiving functions. In actual applications, the baseband chip can control whether the signal generating unit in the wireless USB module is connected to the wireless coupling module, or control the signal receiving unit to be connected to the wireless coupling module, that is, control the switching of the operation between the two, and control the wireless USB signal transmission device to realize the transmission and reception functions.

[0090] Optionally, the wireless USB module further includes a modem unit; the modem unit is configured to up-convert the wireless USB signal generated by the wireless USB module to increase the frequency of the wireless USB signal generated by the wireless USB module; or, down-convert the wireless USB signal transmitted by other devices and received by the wireless USB module through the wireless coupling module to restore the original wireless USB signal generated by the other devices.

[0091] That is to say, the modem unit can perform frequency modulation processing. If frequency modulation processing is performed on the generated wireless USB signal, the frequency of the wireless USB signal generated by the wireless USB module needs to be increased; if frequency modulation processing is performed on the wireless USB signal transmitted by other devices received by the wireless USB module through the wireless coupling module, the frequency needs to be reduced to restore the original wireless USB signal generated by the other device.

[0092] Considering that the frequency of wireless USB signals is not fixed during transmission, and that low bit rates result in a relatively low frequency, hindering wireless USB signal transmission, a modem unit is provided to frequency-modulate the wireless USB signals generated by the wireless USB module. During transmission, this frequency conversion is performed on the wireless USB signals generated by the wireless USB module, increasing their frequency. Accordingly, during reception, if the transmitting side performs the same frequency conversion, the receiving end must use the modem unit to down-convert the wireless USB signals transmitted by other devices, restoring them to a recognizable wireless USB signal. This results in a high frequency USB signal suitable for wireless transmission.

[0093] Please refer to Figure 8 , which shows a schematic diagram of the structure of a wireless USB signal modulation involved in an exemplary embodiment of the present utility model. Figure 8 As shown, the baseband chip includes an original wireless USB signal 801 generated by a signal generation unit, a modem unit 802, and a frequency-modulated wireless USB signal 803. The baseband chip modulates the original wireless USB signal 801 by controlling the modulation signal input from the modem unit 802, and then transmits the frequency-modulated wireless USB signal. In other words, the modulation signal is added to the original wireless USB signal, up-converting the original wireless USB signal, facilitating wireless transmission of the USB signal.

[0094] Please refer to Figure 9 , which shows a schematic diagram of the structure of another wireless USB signal modulation involved in an exemplary embodiment of the present utility model. Figure 9 As shown, the baseband chip includes a wireless USB signal 901 received by a signal receiving unit, a modem unit 902, and an original wireless USB signal 903. The baseband chip controls the modem unit 902 to input a modulation signal to modulate the original wireless USB signal 901, thereby recovering the original wireless USB signal 903 from the received wireless USB signal 901. Specifically, the baseband chip adds the modulation signal to the received wireless USB signal, down-converts the received wireless USB signal, and recovers the original wireless USB signal.

[0095] Optional, Figure 8 and Figure 9The modem unit involved in the above embodiments can be combined with the figures of the other embodiments described above. The modem unit can be positioned between the signal generating unit and the first amplifying device. The wireless USB signal generated by the signal generating unit is first frequency modulated before entering the first amplifying device for amplification and transmission. Alternatively, the modem unit can be positioned between the wireless coupling module and the second amplifying device. The wireless USB signal received by the wireless coupling module is first frequency modulated before entering the second amplifying device for amplification and then entering the signal receiving unit.

[0096] Optionally, under normal circumstances, in addition to USB data transmission, charging can also be achieved through the USB interface.

Among them, the voltage output port and ground port of the wireless USB module can be equivalent to the voltage output port and ground port of the baseband chip. For example, Figure 3 In the process, the wireless charging module is connected through the voltage output port and the ground port of the baseband chip. When charging is needed, a wireless charging connection can be established with the wireless charging modules of other devices through the wireless charging module, and the other devices can charge this device.

[0097] In one possible implementation, the wireless charging module is a planar coil structure; the wireless charging connection established between the wireless charging module and the wireless charging module of other devices is established through coil coupling. Figure 10 , which shows a schematic structural diagram of a wireless USB signal transmission device including a wireless charging module according to an exemplary embodiment of the present invention. Figure 10 As shown, the wireless USB signal transmission device 1000 includes: a baseband chip 1001, a wireless USB module 1002, a wireless coupling module 1003, and a wireless charging module 1004. The first output terminal of the wireless charging module 1004 is led out from the voltage output port VCC of the baseband chip 1001, and the second output terminal of the wireless charging module 1004 is led out from the ground port GND of the baseband chip 1001. The led-out lines are arranged according to Figure 10 The coil structure is formed in a manner such that when a wireless USB signal transmission device establishes a wireless charging connection with another wireless USB signal transmission device, coil coupling is performed through the coil structure to establish a wireless charging connection. Figure 10 The capacitive coupling pad in can also be replaced by Figure 5Coupled resonant devices in .

[0098] Optionally, the wireless USB module further includes a wireless USB interface; the baseband chip is further electrically connected to the wireless USB interface; the baseband chip is further configured to transmit wireless USB signals transmitted by other devices received via the wireless coupling module and the wireless communication connection to the wireless USB interface.

Among them, the application of the wireless USB interface 1105 is mostly in electronic devices. For example, the received wireless USB signal is transmitted to the inside of the electronic device. The wireless USB signal transmission device needs to be connected to the wireless USB interface 1105 to transmit the received wireless USB signal. For example, the applied electronic device is a desktop computer. The USB interface of the desktop computer needs to be connected to the wireless USB signal transmission device provided by this solution according to Figure 11 to connect in a wireless USB signal transmission manner.
