This will allow for a full understanding and implementation of how this application uses technical means to solve technical problems and achieve corresponding technical effects. The embodiments of this application and the various features within them can be combined with each other without conflict, and the resulting technical solutions are all within the protection scope of this application.

[0018] See Figure 1 , 2 A mobile module testing device includes a housing 100, bottom wheels 200, and a testing body; The box 100 is a hollow cuboid, which can be placed or temporarily stored in a small space. The box 100 includes a top plate 150, a side plate and a bottom plate 160. The side plate includes a first side plate 110, a second side plate 120, a front panel 130 and a rear panel 140. The first side plate 110, the front panel 130, the second side plate 120 and the rear panel 140 are connected end to end to form a cuboid. The top plate 150 is enclosed and installed on the top of the side plate, and the bottom plate 160 is enclosed and installed on the bottom of the side plate. The bottom wheel 200 is installed at the bottom of the housing 100, that is, the bottom wheel 200 is installed at the bottom of the base plate 160, which can easily push the test equipment to the production line, laboratory or maintenance area, and provide stable support for the test equipment as a whole during the test. Preferably, the bottom wheel 200 is a high-precision universal wheel with a self-locking mechanism. In module testing, it is usually necessary to accurately control the movement path of the display screen or simulate heavy load conditions. The high-precision universal wheel can provide stable support. The self-locking mechanism can switch between locking and unlocking the wheel by mechanical or electric means, achieving a balance between flexibility and stability. It is suitable for module testing scenarios that require precise control of movement trajectory or fixed position. The main test unit is installed inside the enclosure 100; The test unit includes at least one auxiliary test module interface 300, a power supply 410, a host 420, a screen port 800, a test bus 900, and a speaker 500. The test bus 900 includes test lines 910 and connecting lines 920. The connecting lines 920 are located inside the enclosure 100 and are used for data or signal transmission between the test units. Placing the connecting lines 920 inside the enclosure 100 can significantly reduce the space occupied by messy cable stacking by rationally planning the cable routing, avoid loosening of interfaces or damage to cables due to external pulling, ensure the continuity and stability of data transmission, prevent unauthorized personnel from plugging and unplugging at will and avoid accidental contact, and improve the safety of use. At the same time, the corresponding connecting lines 920 can be centrally organized for easy identification and operation. The screen port 800 is used for connecting an external display screen. Power supply 410 is connected to host 420 and at least one auxiliary test module interface 300 via connecting cable 920; it provides power to host 420 and at least one auxiliary test module interface 300 respectively. Power supply 410 is connected to the power socket of host 420 via power cord to provide stable power to the hardware in host 420, and power supply 410 provides power to auxiliary test module interface 300 via dedicated interface or cable to ensure that auxiliary test module obtains stable and reliable power during testing.

[0019] Preferably, the power supply 410 is a programmable power supply. Programmable power supplies have advantages such as high precision, high efficiency, good stability, and high reliability. They can automatically, accurately, and quickly set and control the output voltage and / or output current through software instructions to meet the needs of testing, research and development, and production. At the same time, programmable power supplies also have multiple protection functions such as overcurrent, overvoltage, and overheat protection to protect the equipment from abnormal conditions.

[0020] In addition, the screen port 800 can be powered by the host 420 or by the power supply 410 as needed: See Figure 4 When the test accuracy is not high, or the test content does not involve power parameters (such as voltage fluctuation, current curve, power consumption analysis), the host 420 has a built-in power supply, such as an ATX power supply, which can meet the power consumption requirements of the display screen. The host 420 can directly power the display screen through the screen port 800. See Figure 5 When the test accuracy is high, or the test purpose is to measure the startup time, shutdown characteristics, power consumption curve, power efficiency, and reliability under abnormal power conditions (such as overvoltage, undervoltage, and surge impact) of the display screen, the programmable power supply directly powers the display screen through the screen port 800.

[0021] The host 420 is connected to at least one auxiliary test module interface 300, screen port 800 and speaker 500 via connecting cable 920; The host 420 includes a chassis shell, and the motherboard, CPU, graphics card, power supply 410, hard drive and memory built into the chassis shell. The chassis shell serves to shield electromagnetic radiation, manage heat dissipation, and facilitate connection and expansion. The host 420 transmits data, control signals, timing and synchronization signals to the test module via the connection cable 920 and the test module interface 300. The companion test module is connected to the companion test module interface 300. The anti-slip module is used to perform core test functions, such as signal acquisition, data comparison, and automated testing. The companion test module interface 300 can be a USB interface, serial port, or other dedicated interface to facilitate data transmission and control between the companion test module and the host 420. A suitable companion test module can be selected as needed to adapt to different test requirements. The host 420 transmits data and control signals to the display screen via the connecting cable 920 and the screen port 800. The display screen is used for data monitoring, test parameter setting, and result analysis. The speaker 500 is used to provide equipment alarm prompts, test voice feedback, or operation instructions, etc. The enclosure 100 has a cable outlet 131 and a screen interface 151 respectively. The front panel 130 has a cable outlet 131, and the top panel 150 has a screen interface 151 in the middle. One end of the test line 910 is connected to at least one auxiliary test module interface 300, and the other end of the test line 910 passes through the outlet 131. The test line 910 is centrally managed through the outlet 131 to avoid clutter and improve operating efficiency. Screen port 800 is installed at screen interface 151. When in use, the display screen is connected to screen port 800.

[0022] The advantages are: integrating the test unit into the housing 100 achieves a compact layout, reducing its volume to 40% of traditional fixtures. Furthermore, the modular design of the test unit within the housing 100 allows for independent disassembly and assembly of each functional module, facilitating maintenance and upgrades. Combined with the casters 200 at the bottom of the housing 100, it allows testers to easily carry the equipment directly to the problem location, enabling a "test-as-needs" work mode. This achieves miniaturization, mobility, and high flexibility of the test equipment, while also enabling rapid fault location, significantly reducing troubleshooting time. The test equipment does not require a fixed workstation, adapting to various production line layouts, and is particularly suitable for multi-variety, small-batch production scenarios. In addition, quick-release interfaces such as the screen port 800 and the auxiliary test module interface 300 eliminate cable constraints, improving disassembly and assembly efficiency.

[0023] In some embodiments, the power supply 410 and the host 420 are integrated into a power supply chassis assembly 400. The power supply chassis assembly 400 is installed at the bottom of the housing 100, that is, it is installed on the top surface of the base plate 160. The power supply 410 and the host 420 are the largest and heaviest components in the test body. Integrating the power supply 410 and the host 420 and installing them at the bottom of the housing 100 can make reasonable use of the space inside the housing 100 and ensure the stability of the test equipment during movement and testing. Preferably, the power supply 410 and the host 420 are arranged flat and stacked on top of each other in the power supply chassis assembly 400 to ensure that the bottom of the housing 100 is evenly stressed, further ensuring the stability of the test equipment during movement and testing. Furthermore, the power supply chassis assembly 400 is detachably installed at the bottom of the housing 100 for easy maintenance and replacement.

[0024] In some embodiments, at least one auxiliary test module interface 300 is installed on the side wall of the enclosure 100, and at least one auxiliary test module interface 300 is located above the power supply chassis assembly 400. When the auxiliary test module is connected to the auxiliary test module interface 300, a predetermined distance is maintained between the auxiliary test module and the power supply chassis assembly 400 to prevent electromagnetic interference between the power supply 410 and the host 420 and the auxiliary test module during operation. In addition, the power supply 410 and the host 420 generate a lot of heat when they are working. To prevent airflow obstruction from causing local temperature rise and affecting the test stability of the auxiliary test module, preferably, at least one auxiliary test module is installed on the inner wall of the first side plate 110, and the cable outlet 131 is opened at the upper end of the front panel 130. Furthermore, at least one auxiliary test module interface 300 is detachably installed on the side wall of the enclosure 100 for easy maintenance or replacement.

[0025] In some embodiments, the speaker 500 is mounted on the side wall of the enclosure 100 and is located above the power supply chassis assembly 400. A predetermined distance is maintained between the speaker 500 and the power supply chassis assembly 400 to prevent electromagnetic interference, mechanical vibration transmission, heat dissipation obstruction, and safety risks. Preferably, the speaker 500 is mounted on the inner wall of the first side plate 110, and the speaker 500 and the test module interface 300 are respectively mounted on different side plates of the enclosure 100 to avoid electromagnetic interference, mechanical vibration transmission, signal crosstalk, heat dissipation problems, and safety risks between them. Furthermore, the speaker 500 can be detachably mounted on the side wall of the enclosure 100 for easy maintenance or replacement.

[0026] In some embodiments, the screen interface 151 is located on the top of the housing 100, i.e., the screen interface 151 is located on the top plate 150. The screen interface 151 is used to install the screen port 800, such as HDMI, DisplayPort, VGA, etc. If the screen port 800 is too close to the power supply 410 or the host 420, it may cause electromagnetic interference, signal attenuation, heat dissipation problems and safety risks during operation, resulting in abnormal display, data transmission errors, equipment overheating or even hardware damage. At the same time, the screen port 800 also needs to maintain a certain distance from the test module and the speaker 500 to prevent electromagnetic interference, mechanical vibration transmission, heat dissipation obstruction and other problems during operation.

[0027] In some embodiments, heat dissipation holes are provided on the housing 100 to ensure the heat dissipation effect when the test body is working, a first heat dissipation hole 121 is provided on the second side plate 120, and a second heat dissipation hole 141 is provided on the rear panel 140.

[0028] In some embodiments, a wire trough 700 is installed outside the housing 100. The wire trough 700 is close to the wire outlet 131 and is used to organize the test wires 910, prevent the test wires 910 from getting tangled, and improve operational safety.

[0029] In some embodiments, the cable tray 700 is detachably mounted on the outer wall of the housing 100 for easy replacement.

[0030] See Figure 3 In some embodiments, the outer wall of the housing 100 is provided with a hanging ear 132, the wire trough 700 includes a U-shaped groove 710 and a hanging plate 720, the hanging plate 720 is provided with a hanging hole 721, the hanging hole 721 and the hanging ear 132 are detachably engaged, the structure is simple and easy to operate.

[0031] In some embodiments, the housing 100 is provided with handrails 600 to facilitate the operator to move the equipment and improve portability. Preferably, a handrail 600 is provided on each side of the top of the top plate 150.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
