[0002] In industrial testing, equipment maintenance, circuit debugging, and communication testing, the portability, functional expandability, and adaptability of testing equipment directly affect the efficiency and applicability of testing operations. Currently, most integrated testing equipment on the market adopts an integrated fixed structure, with fixed functions and inseparable integrated hardware modules, resulting in many drawbacks in use.

[0003] First, traditional integrated testing equipment has limited functionality and cannot flexibly add or remove functional modules according to actual testing tasks. Facing diverse and differentiated testing needs, multiple testing devices with different functions are required, resulting in high procurement costs, inconvenience in portability, and cumbersome maintenance. Second, the integrated structure involves interconnected components; a single module failure can render the entire machine inoperable, leading to poor fault tolerance and stability, and making troubleshooting and component replacement difficult. Third, the existing testing equipment's assembly and disassembly structures lack foolproof limit functions, making reverse connection and incorrect connection problems highly likely, easily causing short circuits and component burnout, posing serious safety hazards. Furthermore, traditional equipment has a fixed power supply mode, unable to adjust power supply according to power status and operational needs, easily causing the entire machine to shut down under low power conditions, affecting the continuity of testing operations. Finally, the existing testing equipment has a rudimentary storage structure, with messy wiring harnesses and components, poor portability, and modules cannot be independently disassembled for use, resulting in extremely low equipment reuse rates and making it difficult to adapt to the needs of outdoor mobile, lightweight, and multi-scenario testing operations.

[0004] Therefore, there is an urgent need to develop a portable multi-functional integrated testing machine and corresponding modular testing methods that are modular, detachable, have precise docking and error prevention, intelligent power supply classification, convenient storage, independent reusability, and high fault tolerance, in order to solve many defects in existing technologies.

Select the required combination of functional units according to the requirements of the detection task.

Assemble the selected functional units by connecting them through the foolproof quick-plug electrical docking terminals.

[0044] Example 2 like Figure 1 and Figure 2 As shown: Based on the content disclosed in Embodiment 1, this embodiment discloses a portable multi-functional integrated testing machine. The overall design adopts a fully modular, split architecture. The core consists of a housing support base, an independently detachable display module 1, a main unit module 2, a power supply module 3, and an expandable peripheral module 4. All functional units are physically independent structures, without rigid wiring harness connections. Each functional unit is equipped with a dedicated start / stop button and an independent power supply circuit, enabling various working modes such as combined use of the entire machine, independent use of a single module, and free combination of multiple modules. This completely breaks through the limitations of the fixed structure of traditional integrated testing equipment. The mechanical locking and positioning, as well as the electrical signal and power transmission connection, between the functional units rely entirely on foolproof quick-plug electrical terminals. Assembly and disassembly can be completed quickly by hand without tools.

[0045] In this embodiment, the foolproof quick-connect electrical terminals are the core connection structure of each module. The male and female connection parts adopt a combination structure of engineering plastic insulating substrate and gold-plated conductive contacts, which has excellent conductivity and is resistant to oxidation and wear during insertion and removal. Among them, the asymmetrical guide post adopts an irregular eccentric structure with one thick and one thin part, which, together with the irregular groove of the female guide slide, eliminates the problem of incorrect insertion and misalignment from the physical structure. The positioning keyway and positioning convex key adopt an irregular arc-shaped misalignment design. The terminal keyway size and curvature are different for different functional modules, realizing the initial error-proof adaptation of the modules. The terminal integrates an elastic locking spring. When the male and female terminals are connected and the electrical contacts are fully engaged and conducting, the spring automatically locks, emitting a clear click sound and tactile feedback. The operator can quickly confirm that the connection is in place, effectively avoiding signal interruption and power supply abnormality caused by loose connection or disconnection. Meanwhile, the gold-plated contact array adopts a matrix-style uniform arrangement, with signal contacts and power supply contacts set in separate zones. The high-voltage power supply area and the low-voltage signal area are physically isolated to avoid signal interference and circuit crosstalk.

[0046] In this embodiment, the housing module 5 is a foldable double-layer protective shell made of high-strength ABS flame-retardant material. Its overall size is suitable for handheld portability. When folded and closed, it forms a regular rectangular box with no protruding structures, facilitating storage and carrying. The housing is formed by hinged upper cover and lower base via a high-precision damping hinge. The damping hinge uses a double-layer damping plate structure, allowing for stepless angle suspension from 0° to 135°. Rigid locking structures are provided at the 0° fully closed and 135° maximum opening angles. The 0° locking position allows for sealed storage, preventing dust and moisture; the 135° locking position fixes the maximum opening angle of the display screen, adapting to the viewing angle of standing inspection work and preventing screen shaking or shifting. An embedded mounting slot is provided on the inner side of the upper cover, where the display module is fixed using a combination of clips and screws, ensuring convenient assembly and disassembly with a secure hold. The lower base adopts a double-layer structure. The upper layer is a flat modular installation platform, divided into independent main unit installation areas, peripheral sub-module array installation areas, and power supply side plug installation areas. The lower layer is a closed wire harness storage compartment. Inside the compartment, wire harness retractors, flexible wire harness clips, and plug positioning slots are neatly arranged, enabling automatic storage and fixation of various testing wire harnesses and connecting cables, preventing wire harnesses from becoming tangled, messy, or worn. Among them, the flexible wire harness clips are made of elastic silicone material, which can accommodate and fix wire harnesses of different thicknesses. The plug positioning slots have built-in embedded magnetic positioning components with moderate magnetic attraction force, which can firmly fix the wire harness plugs, but can also be easily pulled out by hand, balancing fixation stability and ease of use.

[0047] The display module 1 in this embodiment is a high-definition touch display unit. Its screen size is adapted to the layout of portable devices, supporting high-definition image display and touch operation. Parameter settings and data viewing can be completed without an external mouse and keyboard. The module integrates two independent standard video interfaces on its side: an HDMI input interface and an HDMI output test interface, forming a dual-channel video interface system. One channel receives video signals from external testing devices and displays them in real time, while the other outputs standard test video signals, enabling specialized functions such as screen quality testing, video line continuity testing, and display device debugging. Two sets of foldable metal support legs are symmetrically arranged on the back of the display module 1. The legs adopt a damped flip structure, allowing them to be unfolded and fixed at any angle from 0° to 90°. After the module is detached from the casing, it can be independently placed on the support legs and used as a portable screen tester or video signal tester. When working independently, it can be controlled by its own independent start / stop switch, without relying on the main module.

[0048] In this embodiment, the host module 2 is the core control and data processing unit of the device. It is equipped with a high-performance embedded main control chip and integrates core functions such as data processing, signal analysis, module identification, hot-swap control, and communication scheduling. It can independently complete data acquisition, data analysis, fault diagnosis, and parameter output testing. After disassembly, it can be used as a portable data read / write diagnostic host. An embedded rectangular receiving slot is provided on the top surface of the host module for assembling a hidden push-pull keyboard. The keyboard body adopts an ultra-thin, silent key design and slides into the receiving slot via a high-precision silent push-pull guide rail. A built-in elastic limiting buckle is located at the rear of the receiving slot, and a one-piece molded lifting protrusion is formed at the front of the keyboard body. After the keyboard is fully pushed in and stored, the elastic limiting buckle automatically engages and locks, achieving complete concealment without occupying external space. Pressing the lifting protrusion unlocks the buckle, and the elastic lifting component at the bottom of the slot automatically and smoothly pops the keyboard out to the preset usage position, eliminating the need for manual pulling and making operation convenient.

[0049] The main unit module 2 features symmetrical strip-shaped heat dissipation ducts on both sides. These ducts consist of multiple arrays of micro-slits, with each slit measuring 0.3–0.8 mm in width, 8–15 mm in length, and 1.5–3 mm in spacing between adjacent slits. The slits are staggered vertically along the height of the main unit, allowing external cool air to enter from one side and form a meandering airflow path, significantly extending heat exchange time and improving heat dissipation efficiency. A removable dust filter is fitted inside the duct. Made of high-density, breathable non-woven fabric with a breathability of at least 70%, the filter effectively prevents dust and moisture from entering the unit while ensuring effective heat dissipation, thus avoiding dust accumulation and short circuits in the main control chip and circuit components. The main unit module is fully encased in a TPU shockproof and cushioning shell. Multiple hemispherical cushioning protrusions with a height of 1-3mm are evenly distributed on the inner wall of the shell, creating a uniform cushioning air gap between the shell and the main unit body, which can effectively buffer the impact force generated by drops and collisions. The four corners of the shell are thickened, and the thickness of the thickened anti-collision pads is 2-4 times that of the main shell body, specifically enhancing the impact resistance of the equipment's corners and making it suitable for complex working conditions such as outdoor bumps and drops.

[0050] The host module 2 integrates a module identification and hot-swap control unit. This unit has a built-in dedicated identification chip and control program that can monitor the electrical contact continuity of all mating terminals in real time. When a new functional module is plugged in, the connection action is quickly detected through changes in contact signals. The unique type and address codes pre-programmed into the module's storage chip are read to accurately identify the module model, function type, and device address. The corresponding configuration parameters are automatically retrieved, and a dedicated communication protocol stack and power supply voltage and current settings are matched to complete channel allocation and system configuration. When a module is hot-swapped, the corresponding independent power supply circuit is immediately cut off, the communication buffer is cleared, and communication resources are reclaimed. This process does not interfere with the normal operation of other connected modules, achieving a non-destructive hot-swap operation.

[0051] In this embodiment, power module 3 is a detachable, high-capacity lithium battery pack module with an independent, sealed protective structure, providing waterproof, dustproof, and short-circuit protection. The front of the module integrates an independent physical start / stop switch and a digital display of remaining battery power, allowing for real-time and accurate display of the remaining battery percentage, enabling operators to monitor battery status and plan charging times in advance. Power module 3 employs a multi-path independent output circuit design, with foolproof, quick-connect electrical terminals connecting to the power input terminals of the main unit module 2, display module 1, and various peripheral functional sub-modules. Each power supply circuit is independent and does not interfere with others, allowing for individual on / off control of each circuit.

[0052] Power module 3 incorporates an intelligent hierarchical power management unit with two preset power thresholds: a first threshold of 30% remaining power and a second threshold of 10% remaining power, adapting to power control needs under different operating conditions. When the device is connected to an external power source, the system prioritizes charging mode, providing stable power to all functional units while charging the lithium battery pack at a constant temperature and voltage, enabling simultaneous charging and operation. When the remaining battery power falls below the first threshold of 30%, the system automatically cuts off power to all peripheral sub-modules, prioritizing the continuous operation of the two core units: host module 2 and display module 1, while retaining basic detection functions. When the remaining battery power continues to drop to the second threshold of 10%, the system further shuts off power to display module 1, retaining only the host module 2 for minimum operating power consumption, maintaining core data storage and system standby functions, preventing data loss due to sudden power outages, maximizing device battery life, and adapting to long-term operation needs in outdoor scenarios without mains power.

[0053] In this embodiment, peripheral module 5 adopts an expandable array-type modular structure, including four core functional sub-modules: a signal generation sub-module, a data acquisition sub-module, a communication interface sub-module, and a probe detection sub-module. Each sub-module is an independent and detachable unit with its own independent start / stop switch and independent working circuit, allowing for individual start / stop and independent operation. The peripheral mounting area on the base of the housing is equipped with 2×N matrix-style sub-module mounting slots. In this embodiment, 2×4 slots are preferred, totaling 8 sets, which can simultaneously accommodate multiple types of functional sub-modules to meet multi-dimensional synchronous detection requirements. Each set of slots is matched with a set of dedicated foolproof quick-plug electrical terminals, and the positioning keyways and positioning protrusions of the terminals in different slots are unique in shape and size, forming a dedicated adaptation structure. Each type of functional sub-module can only be inserted into the corresponding matching slot, physically preventing incorrect insertion and misinstallation of modules, and ensuring the stability of equipment operation.

[0054] The signal generation submodule can output multiple standard analog and digital test signals, adapting to circuit signal debugging and equipment signal verification operations; the data acquisition submodule can acquire multiple analog data such as voltage, current, temperature, and pressure, realizing industrial equipment condition detection; the communication interface submodule integrates multiple communication interfaces such as RS485, RS232, CAN, and Ethernet, adapting to communication debugging and data transmission detection of different devices; the probe detection submodule is equipped with high-precision detection probes, which can realize accurate detection of circuit board continuity, component parameters, and line faults. The combination of multiple modules can comprehensively cover various operation scenarios such as industrial operation and maintenance, circuit debugging, and communication testing.

[0055] Example 3: Detailed Implementation of Modular Detection Method Based on the portable multi-functional testing all-in-one machine disclosed in Embodiment 2, this embodiment elaborates on its modular testing method. This method relies on the core characteristics of hot-swappable device identification, modular combination, and hierarchical power supply control to achieve lightweight, high-efficiency, and highly adaptable testing operations. The specific detailed operation process and control logic are as follows: S1. Modular Selection and Matching: Before operation, functional unit combinations are precisely selected based on the on-site testing scenario and task requirements. For indoor routine circuit debugging and equipment parameter testing scenarios, a combination of main unit module 2, display module 1, and data acquisition submodule is selected, relying on mains power for operation; for outdoor testing scenarios without mains power or mobile testing scenarios, an additional independent power supply module is selected to ensure continuous equipment operation; for communication equipment debugging and line signal testing scenarios, a communication interface submodule and a signal generation submodule are added; for circuit board fault detection and precision component testing scenarios, a probe testing submodule is selected, matching as needed and without redundancy, reducing equipment power consumption and operating costs.

[0056] S2. Foolproof Precision Assembly: Align the selected functional units and sub-modules with their corresponding mounting slots on the housing, and utilize the asymmetrical guide structure of the foolproof quick-plug electrical terminals to complete the alignment and insertion. During the insertion process, the asymmetrical guide posts and guide grooves automatically correct the insertion orientation, ensuring that only one correct angle allows for smooth insertion and preventing incorrect or reverse connections. Continuously press the module until a clear clicking sound is heard, confirming that the terminals are fully aligned. At this point, the internal electrical contact array is fully engaged and conductive, the mechanical locking structure is fixed, and the module is secure without looseness or gaps, completing the rapid assembly of the entire hardware.

[0057] S3. Automatic System Identification and Configuration: The module identification and hot-swap control unit of host module 2 monitors the conduction status of each docking terminal in real time. When a sudden change in terminal conduction status is detected and a new module is identified, the automatic configuration process is immediately initiated. First, the unique type code and address code pre-burned into the module's storage chip are read through a dedicated identification contact to accurately distinguish the module's function type and device identity. Then, the internally preset module configuration parameter table is retrieved, and the corresponding communication protocol stack, baud rate, communication address, and suitable power supply voltage and current level are automatically matched according to the module type, allocating an independent communication channel and power supply channel for the newly connected module. Finally, a handshake verification signal is sent to the module to complete the bidirectional communication verification. After confirming that the data interaction is normal, the module is officially connected to the system. The entire process requires no manual parameter configuration, achieving plug-and-play functionality. When multiple modules are connected simultaneously, the system can complete the identification and configuration of multiple modules in parallel without interference.

[0058] S4. Modular Start-up, Stop, and Testing Operations: After hardware assembly and system configuration, operators press the independent start / stop switches of each functional unit according to operational needs to individually start the corresponding module for testing. Each module can start / stop independently and work independently, or work collaboratively. Hot-swappable expansion and replacement of modules are supported throughout the operation. If a new testing function is needed, the corresponding functional sub-module can be directly inserted into an empty slot, and the system will automatically recognize, configure, and put it into use. If a faulty module needs to be replaced, the faulty module can be directly unplugged, and the main module 2 will immediately cut off the corresponding power supply channel and reclaim communication resources, while the remaining modules continue to operate normally without interrupting the testing operation. Simultaneously, the display module or main module can be disassembled separately as needed, unfolded with support legs, and placed independently to complete specialized tasks such as screen testing and data diagnostics, demonstrating extremely high equipment reuse flexibility. Throughout the operation, the power module automatically executes a tiered power supply strategy based on the power status to ensure stable operation of the core equipment.

[0059] S5. Finishing Operations and Portable Storage: After the testing task is completed, turn off the independent start / stop switches of each functional unit in sequence to cut off the power supply to each module and avoid power consumption under no-load conditions. Then, return all disassembled functional modules and sub-modules to their corresponding mounting slots on the housing and complete the insertion and fixing. After manually pulling out the testing harness to complete the final testing, release the harness. The spring shaft of the harness retractor automatically releases its stored energy and retracts the harness at a uniform speed. The harness plug is precisely inserted into the plug positioning slot and fixed by magnetic attraction. The elastic harness clips neatly clamp the stored harness to prevent it from becoming tangled. Finally, flip the top cover of the housing downwards and close and lock it at the 0° locking position to form an integrated and neat device. It is compact, easy to carry, store, and transport, and can be directly used for outdoor transportation and warehouse storage.
