Description

Technical Field

[0001] This application relates to the field of railway locomotive lighting technology, and more specifically, to a locomotive headlight. Background Technology

[0002] In railway transportation, locomotive headlights are crucial for ensuring safe operation.

[0003] However, most existing locomotive headlights share a common problem: in high-temperature outdoor environments or during long-term continuous operation, the temperature of the lamp module rises sharply due to the relatively enclosed lamp housing. This excessive temperature rise can have a series of negative effects: on the one hand, it accelerates the decay of the lighting source and significantly shortens its lifespan; on the other hand, it may cause lamp malfunctions, thereby reducing or even completely eliminating the function of providing visibility lighting for the crew, seriously threatening driving safety.

[0004] Although some manufacturers have made improvements to the design of locomotive headlights, due to the limitations of the internal space structure of locomotives, most locomotive headlights on the market are still not equipped with active temperature adjustment devices, and this problem has not been properly resolved for a long time.

[0005] Therefore, designing a locomotive headlight with automatic lamp temperature reduction can adjust the surface temperature of the locomotive headlight under certain environmental conditions, which can greatly improve the service life of the locomotive headlight and the driving safety of the locomotive. Summary of the Invention

The lighting module and the mounting base assembly are connected by screws and adjusting screws through holes in the mounting support plate on the outside of the lighting module and mounting holes on the mounting base assembly, and then tightened with nuts. The adjustment component is connected to the lighting module and is mounted on the mounting base assembly by fixing screws.

[0008] In one possible implementation, the lighting module includes a lamp body and a mounting support plate, the mounting support plate being disposed on the outside of the lamp body for connection with the mounting base assembly.

[0009] In one possible implementation, the mounting base assembly includes a base body, a connecting adjusting bolt assembly, an adjusting spring, an adjusting knob, and wiring terminals; The base body is used to support the lighting module and other components. The combination of connecting adjusting bolts, adjusting springs and adjusting knobs cooperate to realize the angle adjustment of the lighting module. The wiring terminals are used for electrical connection between the components.

[0010] In one possible implementation, the regulating component includes a fan assembly and a monitoring and control assembly. The fan assembly is mounted on the lighting module, and the monitoring and control assembly is mounted on the mounting base assembly and electrically connected to the fan assembly, for monitoring the temperature of the lighting module and controlling the operating status of the fan assembly.

[0011] In one possible implementation, the fan assembly includes a fan body and a mounting bracket for securing the fan body to the lighting module.

[0012] In one possible implementation, the monitoring and control component includes a temperature sensor and a control circuit. The temperature sensor is located near the lighting module to monitor the temperature of the lighting module in real time and transmits the temperature signal to the control circuit. The control circuit controls the start or stop of the fan component according to a preset temperature threshold.

[0013] In one possible implementation, the lighting module and the mounting base assembly are fastened together by screws, adjusting screws and nuts. Specifically, the holes on the mounting support plate on the outside of the lighting module are aligned with the mounting holes on the mounting base assembly, the screws and adjusting screws pass through the holes and are then fastened with nuts.

[0015] The technical solution provided in this application can achieve at least the following beneficial effects: This application provides a locomotive headlight that uses an automatic cooling system to dissipate the heat generated by the lamp module during operation, avoiding accelerated light source decay and lamp component aging caused by high temperatures. This significantly extends the overall service life of the locomotive headlight, reduces equipment replacement costs, and ensures that the headlight can still provide clear and bright visibility for crew members under various complex operating conditions, especially in high-temperature environments and during long-term operation. This effectively prevents traffic safety accidents caused by lamp malfunctions and is of great significance to ensuring railway transportation safety.

[0016] This application provides a modular design for the components, which are connected by standard fasteners such as screws and nuts.

[0024] Before explaining the automatic cooling locomotive headlights provided in the embodiments of this application, the application scenarios and implementation environment of the embodiments of this application will be introduced first.

[0025] In railway transportation, locomotive headlights are crucial for ensuring safe operation.

[0026] However, most existing locomotive headlights share a common problem: in high-temperature outdoor environments or during long-term continuous operation, the temperature of the lamp module rises sharply due to the relatively enclosed lamp housing. This excessive temperature rise can have a series of negative effects: on the one hand, it accelerates the decay of the lighting source and significantly shortens its lifespan; on the other hand, it may cause lamp malfunctions, thereby reducing or even completely eliminating the function of providing visibility lighting for the crew, seriously threatening driving safety.

[0027] Although some manufacturers have made improvements to the design of locomotive headlights, due to the limitations of the internal space structure of locomotives, most locomotive headlights on the market are still not equipped with active temperature adjustment devices, and this problem has not been properly resolved for a long time.

[0028] Therefore, designing a locomotive headlight with automatic lamp temperature reduction can adjust the surface temperature of the locomotive headlight under certain environmental conditions, which can greatly improve the service life of the locomotive headlight and the driving safety of the locomotive.

[0029] Based on this, this application provides a locomotive headlight equipped with an automatic cooling system. The system monitors the headlight temperature using sensors, and a monitoring and control component starts or stops the fan according to a preset temperature threshold, achieving precise heat dissipation for the headlight module. The specific structure includes a headlight module, a mounting base assembly, a fan assembly, and a monitoring and control component. This invention can effectively extend the service life of locomotive headlights, improve driving safety, and has significant practical value and application prospects.

[0030] Next, the technical solutions of this application and how they solve the aforementioned technical problems will be described in detail through embodiments and in conjunction with the accompanying drawings. The embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application.

[0031] Figure 1 This is a schematic diagram of the structure of a locomotive headlight shown in an exemplary embodiment of this application.

[0032] In one exemplary embodiment, such as Figure 1 As shown, a locomotive headlight is provided, which may include a lamp module, a mounting base assembly and an adjustment assembly; The lighting module is mounted on the mounting base assembly. The lighting module and the mounting base assembly are connected by screws and adjusting screws through holes in the mounting support plate on the outside of the lighting module and mounting holes on the mounting base assembly, and then tightened with nuts. The adjustment component is connected to the lighting module and is mounted on the mounting base assembly by fixing screws.

[0033] In one possible implementation, the headlight specifically includes a lamp module 1, a mounting base assembly 2, a fan assembly 3, and a monitoring and control assembly 4.

[0034] The fan assembly 3 is mounted on the lighting module 1 by fixing screws. The lighting module 1 is mounted on the mounting base assembly 2. The lighting module and the mounting base assembly are connected by screws and adjusting screws passing through the holes in the mounting support plate on the outside of the lighting module and the mounting holes on the mounting base assembly, and then tightened with nuts. The monitoring and control assembly 4 is mounted on the mounting base assembly 2 by fixing screws.

[0035] Specifically, such as Figure 2 As shown, the lighting module consists of a lamp body assembly 1 and mounting support plates 2. After three mounting support plates 2 are fastened to the lamp body assembly 1, the lighting module is then connected and fixed to the mounting base assembly 3 via connecting adjusting bolts 4, adjusting knobs 5, and adjusting springs 6. Next, the fan assembly 7 and the monitoring and control assembly 9 are fastened to the mounting base assembly 3 with screws 8 and 10 respectively. Simultaneously, the connecting cables of the monitoring and control assembly, fan assembly, and lighting module are connected together via terminal blocks 11. Thus, the sensor monitors the temperature of the lighting fixture, providing control signals to the monitoring and control assembly to drive the fan, thereby achieving the function of regulating the lighting fixture temperature.

[0036] In use, simply adjust the output signal of the drive control module 9 to the adjustment motor assembly 7, and drive the motor to pull back or push forward the angle adjustment connecting plate, thereby causing the overall angle of the lamp module to shift, thus adjusting the distance between the light emitted by the lamp and the track.

[0037] Figure 2 This is an exploded structural diagram of a locomotive headlight shown in an exemplary embodiment of this application.

[0038] In one possible implementation, as shown in Figure 2, the mounting support plate of the lighting module is first aligned with the base body of the mounting base assembly so that the mounting holes of the two correspond one-to-one.

[0039] Then, the bolt bodies of the connecting adjustment bolt assembly are passed through the holes on the mounting support plate of the lamp module and the mounting holes on the base body in sequence. The adjusting spring is then fitted on, and the adjusting knob is turned on. By rotating the adjusting knob, the extension length of the connecting adjustment bolt assembly is adjusted, thereby causing the lamp module to shift angularly relative to the mounting base assembly, so as to achieve precise adjustment of the light output angle of the lamp module and meet the lighting needs under different track conditions and locomotive operating conditions.

[0040] After adjustment, tighten the adjustment knob to ensure the stability and reliability of the lighting module installation.

[0041] Next, fix the fan assembly bracket to the lamp body of the lamp module, ensuring that the airflow direction of the fan body is directly facing the key heat dissipation parts of the lamp module, such as the LED installation area or heat sink fins.

[0042] Meanwhile, the control circuit of the monitoring and control component is installed on the base body of the mounting base component, and the probe of the temperature sensor is fixed at the designated position of the lighting module. The connecting cables of the fan component, the monitoring and control component and the lighting module are reliably connected to the terminal blocks to ensure the connectivity of the entire circuit system.

[0043] In some embodiments, the headlight specifically comprises a lamp module, a mounting base assembly, a fan assembly, and a monitoring and control assembly.

[0044] The lighting module includes a lamp body and a mounting support plate, wherein the mounting support plate is welded or otherwise reliably fixed to the outside of the lamp body and has multiple mounting holes evenly distributed thereon. The mounting base assembly includes a base body, a connecting adjusting bolt assembly, an adjusting spring, an adjusting knob, and wiring terminals.

[0045] The base body is a metal plate with a certain strength and rigidity. Mounting holes are also provided on it at the positions of the mounting holes of the mounting support plate of the lighting module. The connecting adjustment bolt assembly includes a bolt body and a threaded adjustment part set on the bolt body. The adjustment spring is sleeved on the bolt body, and the adjustment knob is fixedly connected to the end of the bolt body for easy manual adjustment. The wiring terminal is set on one side of the base body for centralized connection of the connection cables of other components.

[0046] The fan assembly includes a fan body and a mounting bracket. The mounting bracket has a "U" shape and its two ends are fixed to the lamp body of the lamp module with screws. The fan body is installed at the opening of the mounting bracket and is detachably connected to the mounting bracket, such as by screws or clips, to ensure that the fan body can stably blow air onto the heat dissipation parts of the lamp module during operation.

[0047] The monitoring and control components include a temperature sensor and a control circuit. The temperature sensor is a high-precision, fast-response thermistor type, with its probe closely attached to the surface of the lamp module or embedded near the heat dissipation components inside the lamp body to accurately sense the real-time temperature of the lamp module. The control circuit is mounted on the base of the mounting base assembly and is connected to the temperature sensor via a connecting cable. It is also electrically connected to other components via terminal blocks. The control circuit integrates key components such as a microprocessor, signal processing circuit, and drive circuit. It can process and analyze the temperature signal transmitted from the temperature sensor in real time and output corresponding control signals to drive the fan assembly to work according to the preset temperature control strategy.

[0048] like Figure 2 As shown, in practical applications, first align the mounting support plate of the lighting module with the base body of the mounting base assembly, ensuring that the mounting holes of both correspond one-to-one. Then, pass the bolt bodies of the connecting adjustment bolt assembly through the holes on the mounting support plate of the lighting module and the mounting holes on the base body in sequence, fit the adjusting spring, and turn on the adjusting knob. By rotating the adjusting knob, adjust the extension length of the connecting adjustment bolt assembly, thereby causing the lighting module to shift angularly relative to the mounting base assembly, achieving precise adjustment of the light output angle of the lighting module to meet the lighting needs under different track conditions and locomotive operating conditions. After adjustment, tighten the adjusting knob to ensure the installation stability and reliability of the lighting module.

[0049] Next, securely mount the fan assembly's bracket onto the lamp body of the lighting module, ensuring the fan's exhaust direction is directly facing the critical heat dissipation areas of the lighting module, such as the LED mounting area or heat sink fins. Simultaneously, install the control circuit of the monitoring and control component onto the base of the mounting base assembly, and fix the temperature sensor probe to the designated position on the lighting module. Reliably connect the connecting cables of the fan assembly, monitoring and control component, and lighting module to the terminal blocks to ensure the continuity of the entire circuit system.

[0050] like Figure 3 As shown, this is during the operation of the locomotive's headlights.

[0051] Step 100: The temperature sensor continuously monitors the temperature changes of the lighting module in real time and transmits the temperature signal to the control circuit in real time.

[0052] Step 200: The microprocessor inside the control circuit processes and judges the temperature signal. When the temperature of the lamp module is detected to reach the preset start-up temperature threshold (e.g., 60°C), it immediately sends a start signal to the fan assembly. After receiving the signal, the fan body starts quickly and the airflow generated by the rotation blows towards the heat dissipation part of the lamp module, quickly carrying away the heat generated during the operation of the lamp module, thereby effectively reducing the temperature of the lamp module.

[0053] Step 300: As the fan continues to dissipate heat, the temperature of the lighting module gradually decreases. When the temperature drops to the preset stop temperature threshold (e.g., 45°C), the control circuit sends a stop signal to the fan assembly in a timely manner. The fan body stops rotating and enters standby mode, waiting for the temperature to rise again before restarting.

[0054] This cycle repeats continuously. By precisely controlling the start and stop of the fan assembly, the monitoring and control components keep the temperature of the lighting module stably within the set safe operating temperature range. This effectively avoids lighting malfunctions and shortened light source lifespan caused by high temperatures, ensuring that the locomotive headlights provide stable and reliable lighting support for the crew throughout their entire service life and guaranteeing railway traffic safety.

[0055] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially as indicated, these steps are not necessarily executed in the indicated order. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
