Description

Technical Field

[0001] This invention relates to the field of electronic device interface and communication technology, and in particular to a multifunctional contactless coupling interface system that does not require physical plugging and its energy and data transmission method, which is applicable to power supply, communication and function expansion between mobile terminals, computing devices and their external devices. Background Technology

[0002] Energy transfer and data communication between existing electronic devices mainly rely on pluggable physical interfaces or wireless communication methods.

[0003] Among them, plug-in interfaces have the following shortcomings: they require precise alignment, are prone to wear, water ingress, and dust accumulation; during use, they are easily restricted by the direction of the cable, affecting the user experience; and their reliability is insufficient in the event of equipment system damage, interface aging, or harsh environment.

[0004] While wireless communication avoids physical connections, it still has the following problems: limited transmission rate, making it difficult to meet the system-level data transmission requirements of high-speed or higher-than-conventional wireless communication; inability to work when the device system is abnormal or the wireless communication module is unavailable; and the stability and security of energy and data transmission are greatly affected by the external environment.

[0005] Therefore, there is an urgent need for a contactless interface solution that requires no physical connection, has high reliability, and supports data transmission at high speeds or higher than conventional wireless communication to meet the usage requirements of various device states and application scenarios.

[0006] This invention is a further technical solution based on the overall technical concept of the contactless coupling interface proposed in the earlier application with application number 2026100722087, and belongs to the continuous technical development under the same inventive concept.

[0007] Compared to prior applications that mainly focus on the basic structural design of contactless coupling interfaces and the implementation of energy and / or data transmission mechanisms, this invention further focuses on the environmental uncertainties that may exist in the coupling region in practical applications.

[0008] To address this, the present invention introduces environmental state detection, safety determination, and adaptive control strategies to dynamically manage the establishment conditions, energy output behavior, and data transmission process of the coupling channel, thereby improving the safety, stability, and reliability of the contactless coupling interface in complex application environments.

[0009] The technical solution described in this invention, while inheriting the prior application technology system, expands its functional dimensions and application capabilities, constituting a technical extension under the same technical route. Summary of the Invention

[0010] Purpose of the invention The purpose of this invention is to provide a multifunctional contactless coupling interface system and its transmission method to solve at least one or more of the following problems: achieving stable power transmission and data communication without physical plugging; supporting high-speed or higher-than-conventional wireless data transmission when the device system is abnormal or the wireless function is unavailable; improving the reliability, durability and freedom of use of the interface; and supporting multi-location, multi-channel interface layout and collaborative operation.

[0011] Technical solution To achieve the above objectives, the present invention provides a multifunctional contactless coupling interface system, including a first device unit and a second device unit, each equipped with a contactless coupling module, forming a controllable or manageable coupling channel without the need for physical plugging, for energy transmission and / or data signal transmission.

[0012] The system also includes a control module, which is used to start and stop the transmission process, switch modes, and adjust parameters after the establishment of the coupling channel is detected.

[0013] The non-contact coupling module can be implemented based on magnetic coupling, electromagnetic coupling, capacitive coupling, inductive coupling, optical coupling, or any combination thereof, and does not depend on a fixed insertion direction or precise alignment. Beneficial effects

[0014] Compared with the prior art, the present invention has at least the following advantages: no physical plugging is required, improving interface durability and reliability; it supports data transmission at high speed or higher than conventional wireless communication, making it suitable for system-level data interaction and device recovery; it allows blind plugging, offset or multi-position layout, increasing the degree of freedom of use; it is compatible with multiple coupling methods, preventing the technical path from being easily bypassed; and it has good scalability, making it suitable for a variety of devices and application scenarios.

Detailed Implementation

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the following embodiments and drawings are only used to explain the technical concept of the present invention, and not to limit the scope of protection of the present invention. The functional modules shown in the drawings are merely illustrative. Those skilled in the art can, according to specific application scenarios, merge, split, replace, add, remove, or omit the modules without departing from the technical concept of the present invention. Equivalent substitutions or modifications should all fall within the scope of protection of the present invention.

[0028] like Figure 1 As shown, this embodiment provides a contactless coupling interface system, which includes, but is not limited to: a coupling interface main module (1), a coupling channel establishment module (2), an energy and data transmission module (3), a safety determination and control module (4), and optional multi-coupling modules or multi-position interface modules (5).

[0029] The modules described above can be connected or work together via wired, wireless, contact, or contactless methods. Their specific structure, quantity, and deployment can be adjusted according to actual application needs and do not constitute a limitation of the present invention.

[0030] like Figure 2 As shown, in one embodiment, when an external device approaches the coupling interface main module (1), the coupling channel establishment module (2) is used to detect whether a target object that meets preset conditions exists. After detecting the target object, the system can establish a controllable energy and / or data coupling channel in at least one coupling region. The coupling channel can be magnetic coupling, capacitive coupling, inductive coupling, optical coupling, or any combination thereof.

[0031] It should be noted that the establishment of the coupling channel can be continuous, hierarchical, or triggered on demand, and the order of establishment and control method do not constitute a limitation of the present invention.

[0032] like Figure 3 As shown, after the coupling channel is established, the energy and data transmission module (3) can realize energy transmission and data transmission in the same coupling channel or different coupling channels. In one embodiment, energy transmission and data transmission can be carried out synchronously; in another embodiment, energy transmission and data transmission can be carried out in a time-sharing, hierarchical, or mode-sharing manner according to a preset strategy.

[0033] The data transmission may include, but is not limited to, low-speed control data, high-speed or higher-than-conventional wireless communication data, or system-level data, and its transmission method does not depend on the normal operation of the operating system, wireless network, or external communication protocol.

[0034] As shown in Figure 4, in a specific implementation, when the connected device is in an abnormal state, a damaged system state, or a state with limited communication functionality, the contactless coupling interface system can still establish a stable data transmission path through the coupling channel. Figure 4 illustrates the schematic structure of data transmission under controlled conditions during this abnormal state or system recovery process. The arrows shown are only for illustrating logical relationships and do not limit the specific implementation method. For example, if the operating system of the connected device is damaged or the wireless communication module is unavailable, the system can automatically or manually switch to the basic data transmission mode to achieve system recovery, data writing, or low-level communication operations.

[0035] It should be noted that the data transmission mode under this abnormal state can exist as an independent mode or as a supplement to the normal mode, and its triggering conditions and control logic can be flexibly configured.

[0036] like Figure 5 As shown, the contactless interface of the present invention can be applied to scenarios with multiple devices, multiple interface locations, or multiple operating states. In one embodiment, the system may include multiple coupling interface modules for establishing coupling connections with multiple external devices simultaneously or sequentially; in another embodiment, multiple coupling interface modules may be deployed at different locations on the same device to adapt to different usage postures or installation requirements.

[0037] The above-mentioned multi-module or multi-location configuration methods can be combined with each other, and their specific implementation methods do not constitute a limitation on the present invention.

[0038] like Figure 6 As shown, the safety determination and control module (4) is used to determine the state of objects within the coupling area before energy or data output. This determination can be based on object type, location, quantity, response characteristics, or historical state information, and accordingly control whether energy output, data output, or a combination of both are allowed.

[0039] It should be noted that the security determination logic can be implemented through software, hardware, or a combination of both.

[0040] like Figure 7 As shown, when a non-target object enters the coupling detection area but does not meet the coupling conditions, the system can enter a detection state without establishing an effective coupling channel. In this state, the system can maintain zero energy output, zero data output, or only perform safety detection operations, thereby avoiding false triggering or safety risks.

[0041] like Figure 8 As shown, when a non-target object further enters the coupling region, the system can maintain a blocking state, limit output, or enter a warning state according to a preset strategy. The strategy can be adjusted based on the object's material, shape, or behavioral characteristics.

[0042] like Figure 9 As shown, when multiple objects enter the coupling region simultaneously, the system can perform multi-object identification and differentiation. In one implementation, the system can establish a coupling channel only for objects that meet the target characteristics; in another implementation, the system can pause all outputs and enter a safety protection state.

[0043] like Figure 10 As shown, the system can dynamically switch between different safety states, including but not limited to: output-prohibited state, output-limited state, normal operation state, and abnormal protection state. The switching of these states can be based on real-time detection results, historical states, or external control commands.

[0044] like Figure 11 As shown, in one implementation, the system can perform hierarchical control of energy output and data transmission. For example, at a low security level, only low-power energy or low-speed data transmission is allowed; after a high security level is confirmed, high-power energy output or high-speed or higher-than-conventional wireless communication data transmission is allowed.

[0045] This classification mechanism can be applied independently to energy or data, or in combination.

[0046] The energy and data hierarchical control method can be dynamically adjusted according to the safety level, and the number of hierarchical levels, the judgment method, and the corresponding relationship are not limited to those shown in the attached figure.

[0047] like Figure 12 As shown, when an abnormal interruption occurs during coupling, the system can automatically enter a recovery process. This recovery process may include re-detection, re-determination, re-establishment of the coupling channel, or rollback to a safe state, thereby ensuring the overall stability and security of the system.

[0048] In one embodiment, the first device unit is a mobile terminal device, and the second device unit is an external power supply and data interaction device. Both the first and second device units are equipped with non-contact coupling modules, which can be implemented using magnetic coupling, electromagnetic coupling, or a combination thereof.

[0049] When the first device unit approaches the second device unit and enters the preset coupling area, the control module detects and judges the object entering the coupling area. After confirming the existence of the target device, a controllable coupling channel is established, and energy transmission and data communication are started.

[0050] In this embodiment, data communication may include low-speed control data and high-speed or higher data transmission than conventional wireless communication. This transmission mode can be used for system-level data interaction, equipment maintenance, or system recovery operations. For example, in the event of an operating system malfunction or unavailability of the wireless communication module in the first device unit, system recovery data can be transmitted to the first device unit through the controllable coupling channel.

[0051] When a non-target object is detected entering the coupling region, or an abnormal coupling state is detected, the control module restricts or interrupts energy transmission and maintains, downgrades, or terminates data communication. Once the coupling relationship is broken or the abnormal state is eliminated, the control module can re-establish the coupling channel according to a preset strategy, restoring energy transmission and data communication.

[0052] In another embodiment, the first device unit is a functional module in industrial or medical equipment, and the second device unit is a maintenance terminal, power supply equipment, or data processing equipment.

[0053] The first device unit may be an external communication module for industrial control equipment, testing equipment, medical monitoring equipment, implantable or semi-implantable medical devices, and its environment may be subject to dust, liquid, vibration, electromagnetic interference, or high requirements for interface reliability.

[0054] The first and second equipment units are each equipped with a non-contact coupling module. When the maintenance terminal or power supply equipment approaches the first equipment unit and enters the preset coupling area, the control module detects and confirms the coupling status and establishes a controllable coupling channel without the need for physical plugging.

[0055] In this embodiment, the controllable coupling channel is used to realize energy transmission and / or data signal transmission during equipment maintenance, system configuration, parameter calibration, or data acquisition. The data signal may include equipment status data, operation logs, configuration parameters, or system program data.

[0056] In the event of device system malfunction, interface contamination, or unavailability of traditional wired interfaces, the controllable coupling channel can be configured to initiate a high-speed or higher-than-conventional wireless communication data transmission mode to enable system-level data writing, firmware upgrades, or device recovery operations.

[0057] In medical device applications, when an unauthorized object or abnormal coupling condition is detected, the control module restricts or prohibits energy output and data communication to improve the safety and reliability of the device. Once the coupling is broken, the first and second device units can terminate, maintain, or downgrade data communication according to a preset strategy, and automatically restore the coupling connection upon re-entering the coupling area.

[0058] It should be noted that the above embodiments are only one of the preferred embodiments of the present invention. Any improvements or substitutions made by those skilled in the art without departing from the concept of the present invention should fall within the protection scope of the present invention.
