Description

Technical Field

[0001] This application relates to the technical field of teaching automotive electrical systems, and more particularly to a training device for automotive lighting control and an automotive lighting system. Background Technology

[0002] In the current teaching and maintenance training of automotive lighting systems, there are obvious deficiencies in the practical equipment: traditional methods often use the whole vehicle's wiring for demonstration and practice, which is not only cumbersome to disassemble and assemble, and easy to cause irreversible damage to the original vehicle's electrical components, but also poses safety hazards such as abnormal wiring load, short circuit and fire. The teaching cost is high and it is difficult to carry out on a large scale.

[0003] On the other hand, while common general-purpose circuit experiment kits on the market can complete basic circuit connections, their design does not closely integrate with the unique working logic of automotive lighting systems, especially the power distribution and interlocking relationships achieved by relays during the switching of high beams, low beams, and parking lights. This prevents trainees from intuitively understanding how relays switch load circuits by controlling the on / off state of coils in practical operation, and also makes it difficult to simulate the working scenario of the linkage between lighting combination switch signals and relays, thus restricting the effectiveness and efficiency of practical teaching. Summary of the Invention

[0004] The main purpose of this application is to provide a training device and system for automotive lighting control. This application aims to solve the technical problems of low teaching efficiency and high practical safety risks in the current field of automotive lighting education due to the lack of targeted, low-cost, and high-safety dedicated experimental equipment.

The first common terminal and the second common terminal are electrically connected to the power supply component through the safety protection component, respectively; the first normally closed terminal and the first normally open terminal are selectively connected to the low beam simulation lamp and the high beam simulation lamp through the terminal block group to form a physical interlock for switching between high and low beams; the second normally open terminal is electrically connected to the parking light simulation lamp through the terminal block group to simulate the opening and closing of the parking light; the signal output terminal of the control switch component is electrically connected to the coil terminal of the relay component through the terminal block group to construct a relay control circuit through external wiring to simulate the logical switching of automotive lights under different operating conditions.

[0008] In one embodiment, the positive and negative terminals of the lighting component are independently connected to the terminal block group, allowing the user to change their connection relationship via external wiring.

[0009] In one embodiment, the high beam simulation lamp and the low beam simulation lamp in the lighting assembly are integrated into a lamp holder, and the lighting assembly uses 12V light-emitting diodes.

[0010] In one embodiment, the five-pin relay is a double silver contact relay; the first normally closed terminal of the five-pin relay is electrically connected to the positive terminal of the low beam simulation lamp via the terminal block, and the first normally open terminal is electrically connected to the positive terminal of the high beam simulation lamp via the terminal block; the training device utilizes the mechanical structure of the five-pin relay to ensure that the first common terminal can only be connected to either the first normally open terminal or the first normally closed terminal at any given time, thereby forming a physical interlock for switching between high and low beams.

[0011] In one embodiment, the safety protection component includes multiple sets of automatic fuses, which are integrated into the operation panel via transparent fuse holders; The multiple sets of automatic fuses include at least three sets of 10A fuses and at least three sets of 15A fuses, which are connected in series in the DC output circuit of the power supply assembly.

[0012] In one embodiment, the power supply assembly includes an AC 220V to DC 12V switching power supply built into the enclosure, and the side of the enclosure is provided with an AC power input socket and a main power physical switch.

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0022] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In current automotive lighting system teaching and maintenance training, traditional teaching methods often involve directly demonstrating and practicing with the entire vehicle's wiring harness. Teachers and students must repeatedly disassemble, reassemble, and measure the electrical system of a real vehicle. This process is not only tedious and time-consuming, but also prone to causing irreversible physical damage to the original vehicle's wiring harness, connectors, and lighting control unit. Furthermore, during training, safety hazards such as abnormal circuit loads, short circuits, and even fires caused by students' lack of proficiency or incorrect connections are real. These hazards not only threaten personal and equipment safety but also keep teaching costs high, making it difficult to conduct large-scale, high-frequency practical training with limited resources.

[0024] Meanwhile, while commercially available circuit experiment kits can help students complete basic circuit connection and switching experiments, their designs often lack the professional focus on automotive lighting systems. Automotive lighting systems—especially high beams, low beams, and parking lights—work not simply through circuit conduction, but through a power distribution and interlocking switching mechanism implemented by relays. General-purpose experiment kits typically cannot reproduce this specific logic, meaning that although students can connect circuits, they cannot visually observe how the switching of the relay coil drives the contact action, thus switching different load circuits. The linkage between the lighting combination switch signal and multiple relays cannot be effectively simulated, causing students to miss the crucial scenario of "small current controlling large current"—the core value of relays—and their understanding of the working principle of "relays as actual switches in lighting circuits" remains abstract.

[0025] To address the aforementioned problems, this application proposes a training device for automotive lighting control, such as... Figure 1 and Figure 2 As shown, the device includes a housing 10 and an operation panel 20 mounted on the housing 10. The operation panel 20 has a terminal block 30. The housing 10 integrates: a power supply assembly 40 for providing power signals; a lighting assembly 50, including a high beam simulation light 51, a low beam simulation light 52, and a parking light simulation light 53; a safety protection assembly 60 for providing overload protection; a control switch assembly 70 for outputting lighting control signals according to user operation; and a relay assembly 80, including at least one set of five-pin relays 81 and at least one set of four-pin relays 82. The five-pin relays 81 have a first common terminal, a first normally open terminal, and a first normally closed terminal; the four-pin relays 82 have a second common terminal and a second normally open terminal. The first common terminal and the second common terminal are electrically connected to the power supply component 40 via the safety protection component 60, respectively. The first normally closed terminal and the first normally open terminal are selectively connected to the low beam simulation lamp 52 and the high beam simulation lamp 51 via the terminal block group 30 to form a physical interlock for switching between high and low beams. The second normally open terminal is electrically connected to the parking light simulation lamp 53 via the terminal block group 30 to simulate the opening and closing of the parking light. The signal output terminal of the control switch component 70 is electrically connected to the coil terminal of the relay component 80 via the terminal block group 30 to construct a relay control circuit through external wiring to simulate the logical switching of automotive lights under different operating conditions.

[0026] This application integrates the power supply, lighting assembly 50, relays, and control switches into the housing 10 and operation panel 20. Trainees can conduct experiments by connecting relays and lights with the same principle as those in the real vehicle using terminal blocks without disassembling the original vehicle. This reduces reliance on original vehicle equipment and professional tools, significantly reducing teaching costs and wear and tear, and effectively lowering the practical skill threshold. Through the corresponding connection of the normally closed and normally open terminals of the five-pin relay 81, the device intuitively reproduces the physical interlocking logic of high and low beam switching; the four-pin relay 82 independently controls the parking lights. Trainees can clearly observe the linkage between relay action and light status changes during operation, improving learning efficiency. The device has a built-in safety protection component 60, providing overload and short-circuit protection, and uses a safe teaching voltage to ensure operational safety.

[0027] Example 1 This embodiment provides a training device for automotive lighting control. The device includes a housing 10 and an operation panel 20 mounted on the housing 10. The operation panel 20 is equipped with a terminal block 30 for electrical connection and connection between external wires and the internal components of the device. The housing 10 integrates a power supply component 40, a lighting component 50, a safety protection component 60, a control switch component 70, and a relay component 80.

[0028] The power supply component 40 provides operating power signals to the entire training device. The power supply component 40 can be a low-voltage DC power module, connected to an external power supply via its input terminal, and providing stable power to the lighting component 50, relay component 80, and control switch component 70 via its output terminal. The output terminal of the power supply component 40 is electrically connected to the common terminal of the relay component 80 via the safety protection component 60, enabling power distribution and output control.

[0029] The lighting assembly 50 includes a high beam simulator 51, a low beam simulator 52, and a parking light simulator 53. The high beam simulator 51 simulates the operation of a car's high beam headlights, the low beam simulator 52 simulates the operation of a car's low beam headlights, and the parking light simulator 53 simulates the operation of a car's parking lights. The input terminals of each simulator are connected to the normally open or normally closed terminals of the relay assembly 80 via terminal blocks 30, and the control of the simulated lighting output is achieved by opening and closing the relay contacts.

[0030] A safety protection component 60 is disposed between the power supply component 40 and the relay component 80 to provide overload protection for the circuit. The safety protection component 60 may include components such as a fuse assembly and an overload protector. When external wiring is incorrect, a short circuit occurs, or the load abnormally increases, the safety protection component 60 disconnects the electrical connection between the power supply component 40 and the subsequent circuit when the current exceeds a set value, preventing damage to the power supply component 40, lighting component 50, and relay component 80 due to overcurrent, while simultaneously limiting the spread of fault current within the enclosure 10. The safety protection component 60 is electrically connected to the output terminal of the power supply component 40 and also electrically connected to the first common terminal of the five-pin relay 81 and the second common terminal of the four-pin relay 82, respectively.

[0031] The control switch assembly 70 is mounted on the operation panel 20 and is used to output lighting control signals according to the user's operation. The control switch assembly 70 may include components such as multi-position selector switches and push-button switches to simulate the main light switch, high / low beam switch, and parking light switch of the vehicle. The signal output terminal of the control switch assembly 70 is electrically connected to the coil terminal of the relay assembly 80 through the terminal block 30. The user can connect different switch outputs to the corresponding relay coil terminals through external wiring to construct different relay control circuits, thereby realizing the on / off control of the high beam simulation light 51, low beam simulation light 52, and parking light simulation light 53 to simulate the changes in the vehicle lighting control logic under different operating conditions.

[0032] The relay assembly 80 includes at least one set of five-pin relays 81 and at least one set of four-pin relays 82. The five-pin relay 81 includes a first common terminal, a first normally open terminal, a first normally closed terminal, and two coil terminals for coil driving. The four-pin relay 82 includes a second common terminal, a second normally open terminal, and two coil terminals for coil driving. The first common terminal is electrically connected to the power supply assembly 40 via a safety protection component 60, and the second common terminal is also electrically connected to the power supply assembly 40 via the safety protection component 60. Both the first normally closed terminal and the first normally open terminal are selectively connected to the low beam simulated light 52 and the high beam simulated light 51 via terminal blocks 30. By changing the external wiring method, the low beam simulated light 52 can be connected to the first normally closed terminal, and the high beam simulated light 51 can be connected to the first normally open terminal. When the coil of the five-pin relay 81 is not energized, the first common terminal and the first normally closed terminal are connected, the low beam simulated light 52 is in the working state, and the high beam simulated light 51 is off. When the coil is energized, the internal contacts of the relay switch, the first common terminal and the first normally open terminal are connected, the high beam simulation light 51 is turned on and the low beam simulation light 52 is turned off, thus physically realizing the interlocking switching of high and low beams and preventing the high beam and low beam from being lit at the same time.

[0033] The second normally open terminal of the four-pin relay 82 is electrically connected to the parking light simulation lamp 53 via the terminal block 30. When the coil of the four-pin relay 82 is not energized, the second common terminal and the second normally open terminal are disconnected, and the parking light simulation lamp 53 is not lit. When the coil is energized, the second common terminal and the second normally open terminal are connected, the parking light simulation lamp 53 receives electrical energy from the power supply component 40, and enters the lit state, thus simulating the on and off process of the parking light. By controlling the on and off of the coil of the four-pin relay 82 through the control switch component 70, learners can observe the response of the parking light in different switching states.

[0034] Specifically, in this embodiment, the relay assembly 80 employs one four-pin relay 82 and one five-pin relay 81. The five-pin relay 81 simultaneously controls both the low beam simulation lamp 52 and the high beam simulation lamp 51 circuits via a first common terminal, a first normally open terminal, and a first normally closed terminal. By connecting the low beam simulation lamp 52 to the first normally closed terminal and the high beam simulation lamp 51 to the first normally open terminal, the switching between low beam and high beam is achieved when the coil state of the five-pin relay 81 changes, reflecting the actual working logic of the vehicle's high / low beam switching relay. The four-pin relay 82 corresponds to the parking light control, connecting the parking light simulation lamp 53 to the second normally open terminal, and achieving single-channel control of the parking light by controlling the coil's on / off state. The coil end, normally open terminal, and common terminal of each relay are led out to the terminal block group 30 on the operation panel 20 via dedicated terminals, and the specific locations of the coil end, normally open terminal, normally closed terminal, and common terminal are marked with text or symbols near the terminals. During practical training, users can connect external wires according to the marking information, and connect the control switch assembly 70, power supply assembly 40, relay assembly 80 and lighting assembly 50 according to the required logic to form a complete control circuit.

[0035] During use, the aforementioned training device utilizes low-voltage bulbs to form the lighting assembly 50, reducing the risk of electric shock and overheating. Overload protection components in the safety protection assembly 60 enable rapid disconnection in case of short circuits and overcurrent. Insulated terminal structures isolate each wiring terminal, reducing the risk of accidental short circuits. Learners can complete the construction, testing, and fault simulation of the lighting control circuit in a non-vehicle environment, reducing reliance on real vehicle electrical systems and lowering costs and safety hazards during teaching and training.

[0036] This training device integrates the power supply component 40, lighting component 50, safety protection component 60, control switch component 70, and relay component 80 within the housing 10. Key nodes are uniformly brought out via the terminal block 30 on the operation panel 20, reducing the need for scattered wiring and multi-device setup. Terminal markings are clear, with coil terminals, normally open terminals, normally closed terminals, and common terminals corresponding one-to-one, allowing learners to complete wiring experiments without specialized tools. This structure facilitates rapid establishment of lighting control circuits by learners of varying skill levels, enabling step-by-step debugging, disassembly and reconstruction, and fault diagnosis training. It is suitable for widespread use in educational institutions and maintenance training scenarios. Through this structural configuration, the automotive lighting control training device in this embodiment comprehensively presents the typical control logic of high beams, low beams, and parking lights, supporting various wiring methods and operating condition simulations to meet diverse application needs such as teaching practice, maintenance personnel training, and basic circuit knowledge training. For further functional expansion, simulated circuits for turn signals, fog lights, etc., can be added to the above structure, with additional relays and switch blocks for further connections.

[0037] Example 2 This embodiment, based on Embodiment 1, further defines and expands the structure and connection relationship of the control switch assembly 70. By simulating the coordinated operation of the ignition switch and the lighting combination switch, the training device is made more closely resemble the actual electrical conditions of a car. The control switch assembly 70 includes an ignition switch and a lighting combination switch. The ignition switch is electrically connected to the power supply assembly 40 and is used to allocate power levels for the training device. The lighting combination switch is electrically connected to the terminal block group 30 and is used to output the control level of each lighting circuit. The signal output terminal of the lighting combination switch is connected to the coil terminal of the relay assembly 80 through the terminal block group 30. By controlling the on / off state of the coil of the relay assembly 80, the status control of the high beam simulation lamp 51, the low beam simulation lamp 52, and the parking light simulation lamp 53 is realized.

[0038] The ignition switch has multiple positions, including LOCK, ACC, ON, and START. The common power input terminal of the ignition switch is electrically connected to the output terminal of the power supply assembly 40. Each position's output terminal is connected to a status indicator light, which indicates the current ignition switch position. When the ignition switch is rotated to a different position, the corresponding output terminal receives voltage from the power supply assembly 40, and the status indicator light illuminates. The status indicator lights clearly distinguish the power output status of the LOCK, ACC, ON, and START positions.

[0039] The power supply module 40 can be an AC 220V input, converted and rectified to output 12V DC voltage. The positive terminal of the 12V DC output of the power supply module 40 is connected to the power input terminal of the ignition switch via a 10A automatic fuse. The 10A automatic fuse automatically cuts off the power output in case of a short circuit or current exceeding a set value, protecting downstream circuits. The output terminals of each ignition switch position are connected to the terminal block 30 via wires. When the ignition switch is in the LOCK position, it only maintains a mechanical locking function and does not output working power. In the ACC position, it provides power to some accessory circuits through the accessory output terminal. In the ON position, it provides power to the lighting combination switch, relay coil, and simulated engine operation-related circuits through the on output terminal. In the START position, it provides power to the simulated start circuit through the start output terminal. By switching the ignition switch positions, the on / off sequence of the working power in each circuit in the training device is consistent with that of an actual vehicle, facilitating trainees' understanding of the power supply logic of different systems under different ignition positions.

[0040] The lighting combination switch uses an automotive headlight combination switch and is installed on the control panel 20. The power input terminal of the lighting combination switch is electrically connected to the ON position output terminal of the ignition switch via the terminal block 30. The high beam signal output terminal, low beam signal output terminal, and parking light signal output terminal of the lighting combination switch are respectively connected to the positive terminal of the coil of the corresponding relay in the relay assembly 80 via the terminal block 30. The negative terminals of all coils are combined and electrically connected to the negative terminal of the power supply assembly 40, forming a complete coil circuit. When the lighting combination switch is switched to different working positions, the corresponding signal output terminal outputs a high level, which is input to the corresponding relay coil via the terminal block 30, causing the corresponding relay coil to be energized and engaged or de-energized and released, thereby controlling the on and off of the high beam simulation light 51, low beam simulation light 52, and parking light simulation light 53.

[0041] The common terminal of each of the aforementioned lighting relays is connected to the positive terminal of the power supply assembly 40 via terminal block 30. The normally open terminal of each lighting relay is connected via terminal block 30 to the positive terminals of the corresponding high beam simulator 51, low beam simulator 52, and parking simulator 53 in the lighting assembly 50. The negative terminals of the high beam simulator 51, low beam simulator 52, and parking simulator 53 are combined and connected to the negative terminal of the power supply assembly 40. Similarly, the negative terminals of each relay coil are combined and connected to the negative terminal of the power supply. Through these connections, when the lighting relay is engaged, its common terminal and normally open terminal are connected, supplying power to the corresponding lighting simulator and illuminating it; when the relay is released, the common terminal and normally open terminal are disconnected, and the corresponding lighting simulator is extinguished.

[0042] For high beam and low beam control, the switching between high and low beams can be achieved through the interlocking of relays. The five-pin relay 81 can be used as a high / low beam switching relay. Its common terminal can be connected to either the low beam relay or the high beam relay input terminal, or its normally open and normally closed terminals can be connected to the positive terminals of the low beam simulator 52 and the high beam simulator 51. This ensures that when the high beam relay is engaged, the circuit controlled by the low beam relay is disconnected, preventing the high and low beams from illuminating simultaneously and reducing the risk of current overload caused by simultaneous operation of high and low beams in real-world driving environments. Using this wiring method, trainees can build and test the high / low beam interlocking control logic during practical training based on the circuit diagram and terminal markings.

[0043] In practical use, after the power supply component 40 is connected to a 220V AC power supply, it is transformed and rectified to output a 12V DC voltage. The positive output terminal is input to the ignition switch power terminal via a 10A automatic fuse. The trainee drives the internal mechanical contacts of the ignition switch by rotating the ignition key, causing the power to be distributed sequentially to the output terminals of LOCK, ACC, ON, and START, realizing the process control from power-off, accessory power supply, vehicle power supply to starting. The ignition switch essentially acts as the master switch for power distribution and on / off control of all systems in the device. Subsequently, according to the training requirements, the trainee connects the signal output terminal of the lighting combination switch to the positive terminal of the corresponding relay coil through the terminal block 30, forming the control links for the high beam circuit, low beam circuit, and parking light circuit.

[0044] Through the above structure, the control switch assembly 70 in this embodiment simulates the actual operation of an automotive ignition switch and a lighting combination switch. The ignition switch provides pre-level control over whether the lighting system is powered. After receiving power from the ON position of the ignition switch, the lighting combination switch drives each lighting circuit to operate by controlling the on / off state of the relay coil. During operation, trainees need to comprehensively judge the working status of the lighting system based on the ignition position, the light switch position, and the relay operation status, which helps them understand the hierarchical power supply structure, power management logic, and lighting control logic of the vehicle's electrical system.

[0045] Through the above embodiments, a clear power transmission and control link is formed between the power supply component 40, ignition switch, lighting combination switch, relay component 80, and lighting component 50. Each stage, from power input, ignition distribution, and lighting signal output to relay driving and lighting load operation, can be built and observed on the training device. This structure facilitates teaching lighting control principles and training in circuit fault simulation and troubleshooting.

[0046] Example 3 Based on the aforementioned embodiments, this embodiment limits and expands the structural form of the lighting component 50 and its connection method with the terminal block group 30, making the connection method of the lighting circuit more flexible in the training process, and facilitating students to construct and adjust various wiring schemes.

[0047] like Figure 2As shown, the positive and negative terminals of the lighting assembly 50 are independently connected to the terminal block 30. The positive terminals of the high beam simulator 51, low beam simulator 52, and parking light simulator 53 are led out to their corresponding positive terminals on the operation panel 20 via wires. The negative terminals of the high beam simulator 51, low beam simulator 52, and parking light simulator 53 are led out to their corresponding negative terminals on the operation panel 20 via wires. The positive and negative terminals of each lighting circuit are not directly fixed inside the housing 10, but are provided to external users as independent terminals through the terminal block 30. During training, users can choose to connect the positive terminals of each light to the normally open, normally closed, or positive terminals of the relays or the power supply via external wires. They can also choose to connect the negative terminals of each light to the negative terminals of the power supply or other test points. This structure allows the connection method of the lighting circuit to be unrestricted by fixed wiring, facilitating experiments with different control logics, different fault conditions, and different wiring methods.

[0048] The high beam simulator 51 and low beam simulator 52 in the lighting assembly 50 are integrated into a single lamp holder. The lighting assembly 50 uses an H4 type high and low beam lamp holder similar to automotive headlights, with high beam and low beam light-emitting units housed inside. The high beam simulator 51 and low beam simulator 52 share the same mechanical lamp holder, with separate high beam and low beam circuits achieved through different pins within the holder. The high beam simulator 51 and low beam simulator 52 correspond to different wiring terminals, allowing the high beam and low beam circuits to be electrically connected independently to different relay control circuits. This integration allows users to distinguish between high beam and low beam on the same lamp holder when observing the lighting status, facilitating comparison and recording of the high / low beam switching effect.

[0049] All lighting components 50 use LED light sources compatible with 12V DC power. The high beam simulator 51, low beam simulator 52, and parking light simulator 53 are all 12V LED bulbs. Using 12V LED bulbs allows for stable brightness under low voltage conditions, reducing energy consumption and heat generation, making them suitable for prolonged use in teaching environments. The LED bulbs are connected to external terminals via lamp holders or lamp holder wiring harnesses. The positive terminal is connected to the normally open or normally closed terminal of the corresponding relay, and the negative terminal is connected to the negative terminal of the power supply. The LED bulbs are turned on and off by controlling the activation and deactivation of the relays.

[0050] In practical implementation, the lighting assembly 50 includes one set of automotive lighting switch assembly, one H4 high / low beam lamp holder, one set of high / low beam bulbs, and one set of parking lights. The automotive lighting switch assembly, in conjunction with the aforementioned lighting combination switch structure, can be used to output high beam, low beam, and parking light control signals. The H4 high / low beam lamp holder is used to install the high / low beam bulbs and provides interfaces for high beam, low beam, and a common terminal. The high / low beam bulbs are 12V LED dual-filament or dual-source bulbs adapted to the H4 lamp holder, forming two independently controllable light sources for high beam and low beam after installation. The parking lights use 12V LED bulbs, installed in a dedicated lamp holder, and connected to the terminal block 30 via wires.

[0051] Each positive terminal of the lighting assembly 50 is connected to an external terminal of the experimental box via a wire, and is labeled as high beam positive, low beam positive, and parking light positive, etc. Each negative terminal of the lighting assembly 50 is connected to an external terminal of the experimental box via a wire, and is labeled as high beam negative, low beam negative, and parking light negative, etc. The above-mentioned lighting terminals and relay terminals form a corresponding connection. During training, users can connect the positive terminal of the high beam simulator 51 to the normally open terminal of the high beam relay, the positive terminal of the low beam simulator 52 to the normally open terminal of the low beam relay or the normally closed terminal of the five-pin relay 81, and the positive terminal of the parking light to the normally open terminal of the parking light relay, according to the circuit diagram and terminal markings; simultaneously, all the negative terminals of the lighting assembly 50 are connected to the negative terminal of the power supply to construct a complete lighting circuit.

[0052] By independently leading the positive and negative terminals of the lighting component 50 to the terminal block 30, this embodiment offers high flexibility in lighting circuit configuration. Users can not only wire according to standard high beam, low beam, and position control logic, but also change the connection methods between the light and relay, and between the light and power supply, according to teaching needs, to demonstrate functional abnormalities, current distribution changes, and fault phenomena caused by incorrect wiring. By integrating high beam and low beam light sources in the same lamp holder and using a standardized 12V LED bulb, this embodiment structurally balances the requirements of demonstrating the high / low beam switching principle with low-voltage DC power supply, facilitating the observation and recording of lighting status changes during practical training.

[0053] Example 4 Based on Embodiment 1, this embodiment further defines the type of the five-pin relay 81 and its connection relationship with the high beam simulation light 51 and the low beam simulation light 52, making the switching logic of high and low beam lights clearer and facilitating the demonstration of the high and low beam interlock control method under single-loop conditions.

[0054] The five-pin relay 81 is a double-silver contact relay. The contact material of the double-silver contact relay is silver-based, offering good rated breaking capacity and current conduction capacity. In this embodiment, a double-silver contact relay with a rated current of 100A is selected to simulate the control scenario of a high-current load in an automotive lighting system. The five-pin relay 81 has a first common terminal, a first normally closed terminal, a first normally open terminal, and two coil terminals. The first common terminal is electrically connected to the positive terminal of the power supply component 40 through the safety protection component 60. The first normally closed terminal and the first normally open terminal are respectively led out to the terminal block 30 and connected to the high beam simulation lamp 51 and low beam simulation lamp 52 of the lighting component 50. The training device utilizes the mechanical structure of the five-pin relay 81 to ensure that the first common terminal can only be connected to either the first normally open terminal or the first normally closed terminal at any given time, thus forming a physical interlock for high / low beam switching.

[0055] The specific connection method is as follows: the first normally closed terminal of the five-pin relay 81 is electrically connected to the positive terminal of the low beam simulation lamp 52 via the terminal block 30, and the first normally open terminal is electrically connected to the positive terminal of the high beam simulation lamp 51 via the terminal block 30. The negative terminals of the high beam simulation lamp 51 and the low beam simulation lamp 52 are respectively electrically connected to the negative terminal of the power supply component 40 via wires. The positive terminal of the coil of the five-pin relay 81 is electrically connected to the high / low beam control signal output terminal of the lighting combination switch or the output terminal of the independent control switch via the terminal block 30, and the negative terminal of the coil is electrically connected to the negative terminal of the power supply. When the coil is not energized, the five-pin relay 81 is in the initial state, the first common terminal and the first normally closed terminal are connected, the positive terminal of the power supply component 40 is output to the first normally closed terminal through the safety protection component 60 and the first common terminal, and then through the low beam simulation lamp 52 circuit to the negative terminal of the power supply. The low beam simulation lamp 52 is in the lit state, and the high beam simulation lamp 51 circuit is in the open state. When the coil is energized, the internal contacts of the relay change, the first common terminal switches from the first normally closed terminal to the first normally open terminal, the low beam simulation lamp 52 circuit is disconnected, the high beam simulation lamp 51 circuit is connected, the positive terminal of the power supply is output to the positive terminal of the high beam simulation lamp 51 through the first common terminal and the first normally open terminal, and the high beam simulation lamp 51 is lit.

[0056] Through the above connection method, the training device realizes single-loop logic switching between high beam and low beam on the same five-pin relay 81. At any given time, only one of the high beam simulator 51 or the low beam simulator 52 is in the on state, while the other is in the off state; there is no situation where high beam and low beam are lit simultaneously. This connection relationship is consistent with the way high and low beam interlocking switching is achieved in actual vehicles using a single dual-contact relay, which helps trainees understand the working process of high and low beam switching through contact switching under a single power supply circuit.

[0057] Because double-silver contact relays possess high rated current capability and contact durability, a 100A-rated double-silver contact relay is selected in this training device. This ensures reliable contact under simulated high-current load conditions, preventing poor contact due to overheating or burning. This configuration allows the device to closely resemble the actual operating conditions of automotive lighting systems in terms of circuit structure and component specifications, while also meeting stability requirements under long-term, repeated operation. During teaching and training, students can observe the changes in the high / low beam simulation lamp 52 when the relay coil is energized and de-energized, analyze the role of the double-silver contact relay in high / low beam interlocking switching using circuit diagrams, and conduct multiple rounds of wiring and fault simulation training under low-voltage conditions.

[0058] Example 5 This embodiment defines the composition and connection method of the safety protection component 60. Multiple sets of automatic fuses provide graded overload protection for the power output circuit, thereby improving the safety and maintainability of the device under conditions of miswiring and faults.

[0059] like Figure 2 As shown, the safety protection component 60 includes multiple sets of automatic fuses. These fuses are integrated onto the operation panel 20 via transparent fuse holders. The transparent fuse holders securely mount each fuse in a designated position on the panel, allowing the user to directly view the fuse's installation status and whether it has blown. The transparent structure facilitates quick visual inspection to determine which fuse is open in the event of an overload or short circuit, thus aiding in fault location and subsequent maintenance or replacement.

[0060] The multiple sets of automatic fuses include at least three sets of 10A fuses and at least three sets of 15A fuses. These fuses are connected in series in the DC output circuit of the power supply assembly 40, forming overload protection units for different branches or functional modules. In specific implementation, the experimental box has six sets of 12V overload protection fuses, three of which are 10A and three are 15A. The 10A fuses can be used to provide overload protection for relay coil circuits, low-power lighting circuits, or control switch circuits, while the 15A fuses can be used to provide overload protection over a larger current range for simulated headlight circuits or the overall main power supply circuit. By matching different fuse specifications to different circuits, reasonable protection thresholds can be set according to the load current of each circuit.

[0061] The positive DC output of power supply component 40 is connected in series with the aforementioned automatic fuses via wires, and then outputs to various electrical nodes such as the ignition switch, power distribution terminal, and common terminal of the lighting relay. This series connection ensures that if a short circuit or overload occurs in any branch, the fuse in the corresponding branch will quickly melt after the current exceeds its rated value, disconnecting that branch from power supply component 40 and preventing the fault current from continuing to propagate to downstream electrical equipment or wiring harnesses. This series structure can also be used to place a fuse in the main power circuit to limit the overall maximum input current of the entire training device.

[0062] When a user causes a short circuit due to wiring errors during training, or when an abnormal load causes the current to exceed the fuse's rated value, the fuse will automatically blow after the current reaches the blowing condition, cutting off the electrical connection between the power supply component 40 and the faulty circuit. The fuse action prevents continuous circuit overload from causing wire overheating, insulation aging, connector erosion, and damage to components such as the lighting component 50 and relay component 80. By installing multiple sets of automatic fuses within the device, overload protection barriers can be built at different circuit levels, limiting the fault current to terminate within a local circuit and preventing it from spreading to the entire electrical system inside the experimental chamber.

[0063] The core function of the automatic fuse in the safety protection component 60 during wiring connections is to form segmented protection nodes in each DC output circuit. When the circuit is in normal operation, the fuse is in a conductive state, maintaining a low-impedance connection within its rated current range, ensuring a stable power supply from the power supply component 40 to the relay component 80, lighting component 50, and control switch component 70. When the current exceeds the design threshold and persists for a certain period, the fuse's metal conductor melts due to heat, breaking the circuit and forming physical isolation. This prevents excessive current from continuing to flow to downstream electrical equipment and wiring harnesses, reducing the risk of burnout, breakdown, and fire caused by overcurrent.

[0064] By employing multiple sets of automatically blowing fuses of different specifications and integrating them into the operation panel 20 with transparent fuse holders, this embodiment makes the layout of the safety protection component 60 in the training device clear and easy to inspect. Before training, users can select appropriate fuse specifications and corresponding circuits according to the experimental content. During training, they can quickly confirm whether there is a short circuit or overload by observing the fuse status. After training, the blown fuses can be statistically analyzed for use in teaching to explain the overload protection principle and the consequences of incorrect wiring. This structure allows students to perform multiple wiring attempts and fault simulations while ensuring circuit safety, improving the usability and durability of the training device.

[0065] Example 6 This embodiment defines the structure of the power supply component 40, the housing 10, and the layout of the operation panel 20, forming a compact automotive lighting control training box with a clear power supply method and well-defined wiring positions.

[0066] The power supply assembly 40 includes a 220V AC to 12V DC switching power supply built into the housing 10. An AC power input socket is located on the left side of the housing 10 for connecting to an external 220V AC power source. The AC input socket is electrically connected to the AC input terminal of the built-in switching power supply. A main power physical switch is located on the side of the housing 10, connected in series between the AC input socket and the switching power supply, used to control the overall power supply to the training device. When the main power switch is off, there is no AC input to the switching power supply, and all DC circuits inside the device are de-energized. When the main power switch is on, AC power is input to the switching power supply via the switch, and the switching power supply converts it to 12V DC output, providing operating voltage for the subsequent lighting assembly 50, relay assembly 80, and control switch assembly 70.

[0067] The built-in switching power supply adopts a 12V, 29A DC output. The output terminals are connected to the corresponding positive and negative power supply terminals on the front of the experimental box via wires. The positive power supply terminal uses a red 2mm insulated terminal, and the negative power supply terminal uses a black 2mm insulated terminal; both are installed in the operating area on the front of the experimental box. Users can run power lines from the positive and negative power supply terminals to provide power to the relay common terminal, control switches, and lighting loads. Color differentiation and terminal markings facilitate quick identification and wiring of the power supply polarity during practical training.

[0068] The control panel 20 is made of 4mm thick aluminum composite panel, serving as the planar structural component of the experimental chamber. The aluminum composite panel has pre-drilled slots for relay mounting, mounting positions for the lighting assembly 50, ignition switch mounting holes, and wiring terminal and fuse mounting holes. The relay mounting slots are used to fix the positions of the four-pin relay 82 and the five-pin relay 81. The mounting positions for the lighting assembly 50 are used to install H4 high and low beam lamp holders and marker light assemblies, making the lights visible on the front panel of the experimental chamber for easy observation of the lighting status. The ignition switch, lighting combination switch, various function switches, and fuse holders are all mounted on the aluminum composite panel. All components are connected to the switching power supply output terminal, main power terminal, wiring terminal block 30, and other functional modules via internal wiring.

[0069] The control panel 20 features printed circuit diagrams, relay pin definitions, and functional labels corresponding to the actual locations of components. The diagrams include key nodes such as the positive terminal for high beams, positive terminal for low beams, positive terminal for parking lights, the negative terminal junction for lights, the relay coil terminal, the main positive terminal for the power supply, and the main negative terminal for the power supply. Relay pin definitions use standardized symbols or text, such as coil terminal, common terminal, normally open terminal, and normally closed terminal, and correspond one-to-one with the actual leads. Functional labels include the ignition switch positions, the function positions of the light combination switch, fuse specifications, and corresponding protection circuits. These labels correspond one-to-one with the component installation locations, allowing users to quickly identify each terminal and its corresponding circuit function directly on the panel based on the printed diagrams and labels, improving wiring efficiency and reducing the probability of wiring errors.

[0070] All terminals feature an insulated design, exposing only the conductive contacts at the front end. The outer surface of the terminals is covered with insulating material, and a safe distance is maintained between terminals. Users complete electrical connections by plugging and unplugging banana plugs or terminal clips. This structure reduces exposed conductive parts, lowering the risk of electric shock due to accidental contact and the risk of accidental short circuits between terminals. Terminals, switches, and fuse holders are uniformly mounted on the front of the test chamber, and are internally organized and secured using wiring channels or wire harness fixing straps, forming a clear internal wiring channel and preventing wires from crossing or tangling.

[0071] The experimental chamber consists of an upper cover and a lower chamber. The outer chamber measures approximately 48cm × 35cm × 15cm, and the inner chamber measures approximately 47cm × 34cm × 14cm. The upper cover is approximately 4cm high, and the lower chamber is approximately 10cm high. The upper chamber houses the aluminum-plastic composite control panel 20, while the lower chamber contains the power supply, power wiring, relay bodies, and other structural components. Four-pin relays 82 and five-pin relays 81 are fixed in pre-drilled slots inside the lower chamber and connected to the relay terminal markings on the control panel 20 via wires. The lighting assembly 50 is mounted on the front of the control panel 20 and fixed in a designated position using a lamp holder or bracket. The relay coil terminals, common terminal, and normally open / normally closed terminals are connected to the terminals on the panel via internal wires. During normal use, the user only needs to perform wiring and operation through the front of the control panel 20; the wiring inside the chamber 10 is not accessible to the user, minimizing the risk of misoperation.

[0072] Through the above structural arrangement, the training box in this embodiment forms a layout of "centralized internal power supply and wiring, and unified external operation and wiring". The switching power supply and high-voltage AC input are installed inside the box 10. Users control the power input of the entire box through the AC power input socket and the physical switch of the main power supply on the side of the box 10. The DC power supply is led out through the red and black main terminals. With the schematic diagram and text labels printed on the panel, students are guided to complete the construction of the lighting circuit, relay control circuit and ignition distribution circuit according to the circuit logic. The positions of each functional component on the operation panel 20 are fixed and clearly marked. With the design of insulated terminals, it is convenient to complete the automotive lighting control training safely and efficiently in a limited space.

[0073] Based on the above embodiments, this embodiment proposes a method for using the training device of this application. In this embodiment, an external connection cable is used to wire and debug the training device, and the specific operation process is as follows.

[0074] First, connect the main power circuit. Connect the positive terminal of the 12V DC power output from the power supply assembly 40 to the fuse input terminal in the safety protection assembly 60 via a wire. Connect the fuse output terminal to the input terminal of the main power distribution switch. Connect the output terminal of the main power distribution switch to the terminals of the ignition switch at each of the following positions: LOCK, ACC, ON, and START. Also connect the common terminal of the low beam relay and the common terminal of the parking light relay. Through the above connections, all positions of the ignition switch and the common terminal of the corresponding low beam and parking light relays are powered by the same 12V power circuit and are protected by the fuse overload protection.

[0075] Next, connect the lighting load to the corresponding relay contacts. Connect the normally open terminal of the high beam relay to the positive terminal of the high beam simulator 51 via a wire, connect the normally closed terminal of the low beam relay to the positive terminal of the low beam simulator 52 via a wire, and connect the normally open terminal of the parking light relay to the positive terminal of the parking light simulator 53 via a wire. Through the above connections, the positive terminals of the high beam simulator 51, low beam simulator 52, and parking light simulator 53 are controlled by the corresponding relay contacts.

[0076] Next, connect the negative circuit. Combine the negative terminals of the high beam simulator 51, low beam simulator 52, and parking light simulator 53 and connect them to the main negative wire. Similarly, combine the negative terminals of the main power control relay coil, high beam relay coil, low beam relay coil, and parking light relay coil and connect them to the same main negative wire. The main negative wire is finally connected to the negative terminal of the 12V DC power supply of the power supply assembly 40. Through these connections, a common negative circuit is formed for all lighting loads and each relay coil.

[0077] Next, connect the relay control switch circuit. Connect the positive terminal of the 12V power supply sequentially to the fuse input terminal, and the fuse output terminal to the main power switch input terminal. Connect the main power switch output terminal, in series with another fuse, to the positive terminal of the lighting combination switch to provide protected control power. Simultaneously, connect the positive terminal of the 12V power supply to the input terminals of the high beam switch, low beam switch, and parking light switch via wires. Connect the output terminal of the high beam switch, low beam switch, and parking light switch to the positive terminal of the high beam relay coil via wires. The negative terminals of each relay coil have been connected to the main negative wire as described above, forming the control circuit for each lighting relay coil.

[0078] After completing the above wiring, check all wiring against the standard wiring example to confirm that all wire connections are correct and there are no short circuits, reverse connections, or loose connections. After confirming that everything is correct, connect the power supply unit 40 to the 12V DC power supply, turn on the main power physical switch, and observe the status of the power level control indicator light (red LED) on the device. When the ignition switch is switched to each level in sequence, the corresponding indicator light will light up sequentially to indicate different power output states such as LOCK, ACC, ON, and START.

[0079] With the power supply functioning normally, the functions of the lighting control and relay operation are verified sequentially. When the parking light switch is closed, the parking light relay coil receives voltage from the 12V power supply, forming a circuit and becoming energized. The common terminal and normally open terminal of the parking light relay are connected, and the parking light simulation lamp 53 receives positive voltage from the power supply. This voltage returns to the negative terminal of the power supply through the negative terminal circuit, illuminating the parking light simulation lamp 53. When the parking light switch is opened, the parking light relay coil is de-energized and released, the common terminal and normally open terminal are disconnected, and the parking light simulation lamp 53 is turned off.

[0080] When the low beam switch is closed, the positive terminal of the low beam relay coil receives power voltage, energizing the coil or maintaining the corresponding control state. The common terminal of the low beam relay is connected to its corresponding output terminal, and the positive terminal of the low beam simulator 52 is connected to the power supply, illuminating the low beam simulator 52. With the low beam simulator 52 illuminated, further closing the high beam switch energizes the positive terminal of the high beam relay coil, causing it to engage. Through a preset relay linkage control relationship, simultaneously with the high beam relay engaging, the low beam relay control circuit is disconnected, or the low beam circuit is disconnected by switching the normally closed / normally open terminal of the five-pin relay 81. At this time, the low beam simulator 52 turns off, and the high beam simulator 51 illuminates, achieving a switch from low beam to high beam operation and preventing simultaneous activation of both high and low beams.

[0081] During the above experiment, if a short circuit or overload occurs in a circuit due to incorrect wiring or abnormal load, the fuse connected in series in that circuit will automatically blow when the current exceeds the rated value, cutting off the electrical connection between the positive terminal of the 12V power supply and the faulty circuit. After the fuse blows, all lighting loads will not light up, and none of the relay coils will engage; the training device will be in a protective shutdown state. Users can observe the transparent fuse holder on the operation panel 20 to identify and replace the blown fuse, while simultaneously checking and correcting the wiring according to the standard wiring example. After confirming that the wiring is correct and replacing the fuse with one of the same specifications, the 12V power supply can be reconnected to repeat the experiment. The above process helps to complete wiring training and fault demonstration of the lighting control circuit while ensuring safety.

[0082] Example 7 This embodiment proposes an automotive lighting system. The automotive lighting system includes the automotive lighting control training device of any of the above embodiments, and an external connection cable for connecting to the terminal block group 30. The external connection cable can be a multi-strand wire or a matching wiring harness, with plugs or clamps at both ends for reliable connection to the terminals on the operation panel 20 of the training device.

[0083] During use, external connection wires are used to connect the control switch assembly 70, relay assembly 80, and lighting assembly 50 according to predetermined circuit logic. The control switch assembly 70 includes an ignition switch and a lighting combination switch. The ignition switch is connected to the output terminal of the power supply assembly 40 via the terminal block 30 to provide power distribution to the lighting combination switch and each lighting circuit. The lighting combination switch is connected to the positive terminal of each relay coil via external connection wires to output high beam, low beam, and parking light control signals.

[0084] The relay assembly 80 includes at least one four-pin relay 82 and at least one five-pin relay 81. The common terminal of the five-pin relay 81 is connected to the positive terminal of the power supply assembly 40 or the ON position output terminal of the ignition switch via an external connection cable. Its normally closed terminal is connected to the positive terminal of the low beam simulated lamp 52 via an external connection cable, and its normally open terminal is connected to the positive terminal of the high beam simulated lamp 51 via an external connection cable. The common terminal of the four-pin relay 82 is connected to the positive terminal of the power supply assembly 40 or the power distribution terminal via an external connection cable, and its normally open terminal is connected to the positive terminal of the parking simulated lamp 53 via an external connection cable. The negative terminals of each relay coil are connected to the negative terminal of the power supply via external connection cables.

[0085] The positive and negative terminals of the high beam simulator 51, low beam simulator 52, and parking light simulator 53 in the lighting assembly 50 are connected to the terminal block 30 via external connecting wires. The negative terminals of all the lights are then connected to the negative terminal of the power supply assembly 40 via external connecting wires, forming a complete loop return path.

[0086] Through the connection of the aforementioned external connecting wires, a complete lighting control circuit is formed between the control switch assembly 70, the relay assembly 80, and the lighting assembly 50. In this lighting control circuit, the normally closed terminal of the five-pin relay 81 is connected to the positive terminal of the low beam simulation lamp 52, and the normally open terminal is connected to the positive terminal of the high beam simulation lamp 51, with the common terminal connected to the same power supply circuit. By controlling the on / off state of the coil of the five-pin relay 81, the physical interlocking switching of the low beam simulation lamp 52 and the high beam simulation lamp 51 under the same power supply circuit is achieved. When the relay coil is not energized, the low beam simulation lamp 52 is on and the high beam simulation lamp 51 is off; when the relay coil is energized, the high beam simulation lamp 51 is on and the low beam simulation lamp 52 is off, ensuring that the high beam and low beam lamps will not be lit simultaneously in this system.

[0087] The aforementioned automotive lighting system, through the combination of a training device and external connecting wires, forms a lighting control circuit with physical interlocking functionality for high and low beams. This system is suitable for training in assembling automotive lighting circuits, demonstrating control logic, and teaching the principle of high and low beam interlocking. It can also be used to verify the impact of different wiring and control methods on the working state of the lights.

[0088] The above description is only a part of the embodiments of this application and does not limit the patent scope of this application. All equivalent structural transformations made under the technical concept of this application and using the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this application.
