Specific embodiments

[0036] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in conjunction with the embodiments.

[0037] As Figures 1 to 9 shown, an embodiment of the present utility model provides a power and lighting system test device, including: a test bench 24, on which a power system, a lighting system and a control system are integrated. The power system, the lighting system and the control system are connected to each other. The lighting system and the control system are respectively connected to a battery 17. The power system is connected to a fuel tank 20, the fuel tank 20 is connected to an ignition system, and the ignition system is connected to the control system.

[0038] The present utility model manufactures a power and lighting system test device for a teaching machine based on the corresponding model of a transport vehicle. It uses the electronically controlled high-pressure common rail diesel engine 9, gearbox 8 and the original vehicle lighting system that are matched with the original vehicle, integrates an auxiliary system, and operates normally, and can be used as an on-line detection experiment platform. This device can perform practical operations on the engine 9, gearbox 8 and lighting system under working conditions such as starting, accelerating, decelerating, shifting gears, and switching lights, and truly demonstrates the structure and working process of this power and lighting system. It is suitable for vehicle training institutions to conduct practical training on this power and lighting system. This device covers the practical operations of the engine 9, gearbox 8 and lighting system, and supports mobile teaching, not limited to a fixed installation position. In this embodiment, an integrated and modular power and lighting system training test device realizes the linkage control of the power system and the lighting system, and improves the teaching efficiency.

[0039] In this embodiment, the power system includes an engine 9 and a transmission 8, with the engine 9 connected to the transmission 8, which in turn is connected to a joystick 27. The engine 9 is the core power source, simulating the power output of a real vehicle and allowing for performance testing under different speeds and loads. The transmission 8 is used to adjust the power transmission ratio, simulating shifting conditions and verifying transmission matching. The joystick 27 is used to manually control the gear shifting of the transmission 8, achieving dynamic adjustment of power output. The entire power system constructs an adjustable power output link, supporting collaborative testing and educational demonstrations of the engine 9 and transmission 8. It supports independent testing of the powertrain without relying on the vehicle environment. The joystick 27 enables visual adjustment of gear positions, facilitating trainees' understanding of the mechanical transmission logic. The engine 9 burns fuel to generate kinetic energy, the transmission 8 changes torque and speed through gear sets, and the joystick 27 mechanically selects the transmission ratio, forming a complete power transmission path.

[0040] In this embodiment, the control system includes a console, a steering wheel 4, a brake pedal 23, an accelerator pedal 3, and a joystick 27. The console has a steering wheel assembly 5 connected to the steering wheel 4. The lower end of the console has the brake pedal 23 and the accelerator pedal 3. The joystick 27 is mounted on the chassis 28. The steering wheel assembly 4 is used to simulate steering input, triggering the turn signal 21 (linked with the lighting system). The brake pedal 23 and the accelerator pedal 3 are used to control braking pressure and the throttle opening of the engine 9, replicating driving operations. The joystick 27 is used for gear shifting control independently of the steering wheel 4, avoiding operational interference. The control system integrates driving control input devices, realizing an "operation-response" closed loop to simulate a real driving environment. The centralized layout of multiple control components improves human-machine interaction efficiency, and the mechanical separation design of the pedals and steering wheel 4 reduces the risk of misoperation. A closed-loop test of operation and system linkage is formed through the control system operation input (e.g., pressing the accelerator) → sensor and mechanical structure signal transmission → engine 9 and lighting system response → instrument panel 22 feedback parameters (e.g., engine speed).

[0041] In this embodiment, the lighting system includes a taillight 2, a headlight 30, and a turn signal 21. The taillight 2 is mounted on a test bench 24, the turn signal 21 is mounted on a control panel, and the headlight 30 is mounted at the front end of the test bench 24. The taillight 2 is used to test the brake light and parking light functions and verify the circuit load capacity. The turn signal 21 is linked to the steering wheel 4 to detect the turn signal triggering and flashing frequency. The lighting system independently verifies the lighting circuit logic and its coordination with other systems (such as the control system). The lighting module is independently testable, avoiding interference from the complexity of the vehicle's electrical circuitry. The turn signal 21 is mechanically bound to the steering wheel 4, visually demonstrating the signal transmission relationship. Rotation of the steering wheel 4 → mechanical and electrical signals trigger the turn signal 21 → current is supplied through the battery 17 → the light illuminates, verifying circuit continuity and load stability.

[0042] In this embodiment, the test bench 24 includes a chassis 28, a suspension bracket 15, and a guardrail 29. The guardrail 29 is mounted on the chassis 28, and a seat 1 is mounted on the chassis 28. The chassis 28 supports the power system and control system, providing a rigid support foundation. The guardrail 29 prevents personnel and components from accidentally falling during testing, ensuring safety. The seat 1 fixes the operator's position, simulating a driving posture. The test bench 24 constructs a safe and stable testing platform, adapting to ergonomic requirements. The guardrail 29 and chassis 28 are integrated, balancing equipment rigidity and operational safety. The seat 1 is adjustable to accommodate users of different body types. The chassis 28 disperses vibrations from the power system through structural mechanics design, the guardrail 29 resists external impacts through rigid connections, and the seat 1 adapts to human body dimensions via adjustable rails, creating a safe testing environment.

[0043] In this embodiment, the control console includes an instrument panel 22, a function switch 6, and a teaching board. The teaching board can be mounted on the control console or set up independently. The instrument panel 22 is used to display key parameters such as engine speed, oil pressure, and lighting status in real time. The function switch 6 is used to manually control the start and stop of subsystems such as lights and ignition. The teaching board is a transparent panel that displays circuit wiring and supports fault simulation teaching. It centralizes information display and system control, supporting data monitoring and teaching demonstrations. The teaching board features a visual circuit design, making it easy for students to understand the electrical connection logic. The instrument panel 22 integrates multi-parameter displays, reducing reliance on external testing equipment. Sensor data acquisition → Instrument panel 22 converts data into visual signals → Function switch 6 controls the system through circuit on / off switching → Teaching board exposes the wiring for observation, forming a three-in-one function of "monitoring-control-teaching".

[0044] This embodiment also includes a fan 14, a fan outer ring 11, a radiator 12, and an intercooler 13. The fan 14 is positioned close to the engine 9, the radiator 12 is positioned close to the fan 14, and the intercooler 13 is positioned close to the radiator 12. The fan 14 is used to cool the engine 9 and surrounding components through airflow. The fan outer ring 11 provides protection, and the radiator 12 is used to reduce the temperature of the engine 9 through coolant circulation. The intercooler 13 is used to reduce the intake air temperature after boosting, improving combustion efficiency. Overall, it maintains the thermal balance of the power system, ensuring stability during long-term testing. The radiator 12 and fan 14 work together to prevent test interruptions caused by engine overheating, and the intercooler 13 improves intake efficiency, simulating performance under real-world conditions. The process—engine 9 high temperature → radiator 12 circulating coolant for heat dissipation → fan 14 enhancing air convection → intercooler 13 compressing and cooling the intake air—forms a multi-stage thermal management mechanism.

[0045] This embodiment also includes an auxiliary disassembly and assembly crane 19, which is mounted on the platform 24. The auxiliary disassembly and assembly crane 19 provides mechanical assistance to help disassemble heavy components such as the engine 9 and gearbox 8, reducing maintenance difficulty, improving equipment reuse efficiency, reducing the risk of manual handling, shortening component replacement time, and supporting modular teaching (such as demonstrating the internal structure of the engine 9). The crane 19 provides lifting force through a pulley system and an electric motor → the operator controls the boom movement components of the crane 19 → achieving rapid disassembly and assembly.

[0046] This embodiment also includes omnidirectional locking casters, which are located at the lower end of the chassis 28. The omnidirectional casters allow for 360° rotation, adapting to narrow spaces. The locking device fixes the position of the platform 24, preventing slippage during testing. This allows for flexible deployment and stable fixation of the equipment, facilitating convenient movement to meet the needs of various scenarios (classroom / workshop). When locked, the chassis 28 rigidly contacts the ground, reducing vibration interference. Rolling friction of the casters reduces movement resistance; when locked, the brake pads press against the axle, fixing the position through friction.

[0047] In this embodiment, the ignition system includes an ignition switch assembly, a control circuit for on / off switching, and a safe engine start system 9. It enables one-button ignition operation, simulates the vehicle start-up process, and links the ignition switch with the battery 17 to avoid the risk of accidental start-up. The assembly integrates multiple ignition methods such as key and button to adapt to different teaching scenarios. The sequence is: key rotation / button pressing → battery 17 circuit connection → spark plug ignition → engine 9 start-up, replicating the standardized ignition process.

[0048] In this embodiment, it also includes an air filter 7, a water bottle 10, a door lock 16, an oil filter 18, a gas canister 25, an exhaust pipe 26, and a guardrail 29. The air filter 7 is used to filter air, the oil filter 18 is used to filter fuel, the water bottle 10 is used to provide water, the door lock 16 is used to lock the guardrail 29, the exhaust pipe 26 is used for the engine 9 to discharge exhaust gas, and the gas canister 25 is used to provide gas to the engine.

[0049] In this embodiment, a fault diagnosis instrument and intelligent fault setting system for this engine 9 can also be equipped, which can perform fault code reading operations on the electronic control system.

[0050] Working principle:

[0051] Power system operation: Battery 17 supplies power to the ignition system, and the control system controls the engine 9 to start via the ignition switch assembly; fuel is supplied to the engine 9 from the fuel tank 20, and power is transmitted to the output end via the gearbox 8. The lever 27 adjusts the gear of the gearbox 8 to simulate different operating conditions.

[0052] Lighting system linkage: The steering wheel assembly 4 of the control system triggers the turn signal 21, the function switch 6 controls the taillights to turn on and off, and the instrument panel 22 displays the lighting status in real time, realizing the circuit logic verification consistent with the actual vehicle.

[0053] Control feedback and data monitoring: The driver inputs commands through the steering wheel 4, pedals and control lever 27. Engine speed, oil pressure and other parameters are fed back through the instrument panel 22. The teaching board displays the circuit signal flow, forming a closed loop of "operation-response-monitoring".

[0054] Auxiliary function coordination: Fan 14 automatically starts and stops according to the temperature of engine 9, working with radiator 12 and intercooler 13 to reduce system heat load; after the omnidirectional casters are unlocked, they push the test stand 24 to move, and after locking, they fix the test position to ensure stability.

[0055] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0056] Integrated and modular training equipment enables the coordinated control of the power system and lighting system, thereby improving teaching efficiency.

[0057] Integrated testing and teaching functions: The test bench 24 integrates the power system (engine 9, gearbox 8), lighting system (taillight 2, turn signal 21) and control system (steering wheel 4, brake pedal 23, accelerator pedal 3, instrument panel 22), realizing the linkage testing of power output, lighting control and driving operation, which significantly improves testing efficiency and facilitates intuitive teaching demonstrations.

[0058] Modular and scalable design: Through components such as teaching boards and function switches, it supports modular disassembly teaching of system circuits and mechanical transmissions, and can quickly disassemble and assemble components with the help of a crane to adapt to different training scenarios.

[0059] Heat dissipation and stability optimization: The coordinated layout of fan 14, radiator 12 and intercooler 13 ensures the stability of engine 9 during long-term operation and avoids performance deviations caused by overheating during testing.

[0060] Mobility: The chassis 28 is equipped with omnidirectional locking casters, which can flexibly adjust the position of the equipment and fix it, making it suitable for various scenarios such as workshops and classrooms.
