Description

Technical Field

[0001] This utility model relates to the field of warning light technology, and in particular to a traffic accident prevention and control warning light. Background Technology

[0002] In the field of road traffic management, efficient command tools are indispensable for traffic accident prevention and on-site traffic control. Among them, traffic accident prevention command warning lights are one of the core equipment for traffic police on-site duty, and their performance directly affects command efficiency and road traffic safety. At present, the existing traffic accident prevention command warning lights on the market have formed a relatively mature basic structure, mainly including a handle for personnel to hold, a white bulb installed on a lamp holder at one end of the handle, and a multi-colored transparent lampshade covering the white bulb. To realize the adjustment of the warning function, the handle is usually equipped with a button, and the inside of the handle is equipped with a circuit board electrically connected to the button. The button can control the opening and closing of the white bulb and the working mode (constantly on or flashing). The white light emitted by the white bulb passes through different color areas (such as red, yellow, and green areas) of the transparent lampshade and can present the corresponding color light from the outside, thereby improving the visibility of the command personnel at night or in low-light environments.

[0003] From the perspective of practical application scenarios, the core value of this type of traditional warning light lies in attracting the driver's attention through luminous warning: on the one hand, it avoids the driver being unable to see the person directing traffic in time due to dim lighting, thus reducing the risk of collision; on the other hand, the luminous state can help the driver to more clearly recognize the gestures of the person directing traffic, thereby cooperating to complete operations such as adjusting the driving direction and changing lanes, playing an important role in regular traffic management scenarios.

[0004] However, with the continuous growth of urban road traffic flow, the increasing number of complex intersections (such as multi-lane intersections and highway entrances / exits), and the varying levels of understanding of traffic hand signals among different drivers, traditional warning lights can only achieve the function of "warning presence" through colored light, and cannot convey specific traffic instructions (such as "stop," "wait," and "proceed"). In actual traffic control, drivers need to rely on observing the traffic police's hand signals to determine their driving intentions, but due to various factors—such as blurred car windows in rainy weather, insufficient light at night leading to low hand signal recognition, or some novice drivers and out-of-town drivers being unfamiliar with standard traffic hand signals—misunderstandings of hand signals are very likely to occur. At this time, traffic police often need to approach the vehicle to communicate verbally to clarify instructions, which not only prolongs traffic control time but also increases the safety risks for traffic police moving through traffic, especially during peak hours or congested sections, easily exacerbating road traffic pressure.

[0005] Therefore, we propose a traffic accident prevention and control warning light to address the aforementioned problems. Utility Model Content

[0006] This utility model provides a traffic accident prevention and control warning light to solve the aforementioned technical problems.

[0007] The present invention adopts the following technical solution: it includes a handle, a white light bulb installed on the handle lamp holder, and a transparent lampshade with multiple colors disposed outside the white light bulb, and also includes at least one luminous sign located on the transparent lampshade. The sign assists traffic police in directing traffic and helps drivers accurately understand the traffic signals issued by the traffic police through its luminous effect.

[0008] Furthermore, the sign includes a substrate connected to the transparent lampshade, illuminated characters mounted on the substrate, and a transparent shell clipped onto the substrate.

[0009] Furthermore, multiple signs are located on the upper part of the transparent lampshade and are evenly installed on the outside of the transparent lampshade around its axis.

[0010] Furthermore, multiple signs are linearly arranged on the outside of the transparent lampshade along a direction parallel to the axis of the transparent lampshade, and the illuminated lettering of all signs faces the same direction.

[0011] Furthermore, there are three signs, each with illuminated characters for "Stop", "Wait", and "Go".

[0012] Furthermore, the handle is also equipped with a speaker, which is used to broadcast the voice corresponding to the current working status of the sign. Several sound holes are opened at one end of the handle near the lamp holder, and the speaker is installed inside the handle at the position corresponding to the sound holes.

[0013] Furthermore, the transparent lampshade includes a red transparent cover, a yellow transparent cover, and a green transparent cover from top to bottom. The white light emitted by the white bulb passes through the transparent covers of different colors and then appears as light of the corresponding color from the outside, enhancing the warning effect at night.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: By adding illuminated signs to traditional warning lights, the "Stop," "Wait," and "Go" indicators on these signs can clearly convey specific traffic instructions, completely solving the problem that traditional warning lights can only "warn of presence" but cannot convey clear instructions. Drivers no longer need to rely on hand gestures; they can quickly understand driving requirements directly through the illuminated signs, effectively avoiding misunderstandings caused by blurred windows in rainy weather, insufficient light at night, or unfamiliarity with traffic hand gestures.

[0015] Because the illuminated signs are clear and easy to understand, traffic police no longer need to approach vehicles for verbal communication, which shortens traffic control time and avoids the safety risks of traffic police weaving through traffic, significantly improving the safety and efficiency of on-site command.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] likeFigures 1-2 As shown, this is a conventional traffic accident prevention and warning light of the present invention. It mainly includes a handle 5, a white bulb 10 mounted on a lamp holder 9 of the handle 5, and a transparent lampshade 6 with multiple colors on the outside of the white bulb 10. When using the handle 5, the person holds the handle 5. The handle 5 has a button 4, which is used to control the illumination of the white bulb 10. The white bulb 10 is mounted on the lamp holder 9 of the handle 5. A transparent lampshade 6 with multiple colors is also provided on the outside of the white bulb 10. After white light passes through the different colored areas for filtering, it appears as light of the corresponding color from the outside. For example, if white light passes through the green lampshade, it appears as green light from the outside. In addition to controlling the opening and closing of the white bulb 10, the button 4 is also used to control the working status of the white bulb 10, that is, the constant light or flashing mode. The specific adjustment mode is realized through the button 4 on the handle 5. The handle 5 has a circuit board 8 connected to the button 4 inside. The circuit board 8 controls the state of the white bulb 10. When the command personnel hold this device, it is more visible at night, preventing drivers from being unable to see the command personnel due to poor lighting. At the same time, because the warning light is illuminated, it is also easier for drivers to see the corresponding hand gestures made by the command personnel, so as to cooperate with the command personnel in driving. The above is an introduction to the existing traffic accident prevention command warning lights.

[0020] As can be seen from the above, the existing traffic accident prevention and control warning lights have the following defects when in use: the warning lights can only provide light warnings, and during the process of directing traffic, some drivers cannot accurately understand the gestures of the person in charge, and the person in charge needs to get closer and communicate verbally to guide the traffic. Based on the above problems, this utility model adopts the following improvement method to solve them.

[0021] like Figures 1-2As shown, a traffic accident prevention and control warning light, based on existing technology, adds a luminous sign 14. The sign 14 is at least one in number and is located on a transparent lampshade 6. It assists traffic police in directing traffic through illumination and helps drivers accurately understand traffic signals issued by the police. The sign 14 mainly includes a base plate 13 connected to the transparent lampshade 6, luminous characters 12 mounted on the base plate 13, and a transparent shell 11 clipped onto the base plate 13. The transparent shell 11 completely seals and covers the internal components. Combining the flame-retardant ABS base plate 13 (high temperature resistant, fireproof) and the impact-resistant PC transparent shell 11 (collision resistant, anti-aging), it effectively prevents rainwater and dust intrusion, adapts to rainy days, sandstorms, and other harsh weather, extends the equipment's service life, and reduces maintenance costs. The base plate 13 is fixedly connected to the lampshade, such as by a snap-fit / Screws are used for fixing, combined with anti-slip silicone pads (0.3-0.5mm) to increase the friction of the contact surface and prevent the indicator sign 14 from loosening or shifting when the equipment is shaken or slightly bumped. The detachable snap-fit ​​design of the transparent shell 11 ensures the stability of the indicator sign 14 and facilitates subsequent troubleshooting of the illuminated letter 12 (such as replacing LED beads) without disassembling the entire warning light, improving maintenance efficiency. At the same time, the light transmittance of the transparent shell 11 is ≥90%, ensuring clear signal transmission of the illuminated letter 12 without affecting the indication effect. The flame-retardant substrate 13 can reduce the risk of fire caused by circuit failure, and the impact-resistant transparent shell 11 can withstand minor collisions (such as accidental drops or vehicle scratches), reducing the probability of equipment damage and ensuring the continuity of traffic police on-site command. Similar to existing technology, the transparent cover includes a red transparent cover 1, a yellow transparent cover 2, and a green transparent cover 3 from top to bottom. The white light emitted by the white bulb 10 passes through the transparent covers of different colors and presents the corresponding color light from the outside, enhancing the nighttime warning effect, such as... Figure 5 and 8As shown, there are three signs 14, and each sign 14 has an illuminated "Stop", "Wait", and "Go" sign 12. The illuminated "Stop", "Wait", and "Go" signs 12 are all made of LED light bead arrays or EL cold light sheets. The font height is 1 / 2 to 2 / 3 of the height of the substrate 13, and the character stroke width is 5-8mm, ensuring 10-50 Clearly identifiable within a meter range; the handle 5 has a button 4, and the handle 5 contains a circuit board 8 electrically connected to the button 4. The circuit board 8 is electrically connected to the white bulb 10 and the illuminated characters 12 of the sign 14. The button 4 controls the on / off state and working status of the white bulb 10 (working modes include constant light mode and flashing mode). The three illuminated characters 12 are independently electrically connected to the control circuit board 8. The function button 4 can control the illumination of any one of the illuminated characters 12, and also controls the illumination status of a single sign 14. Only one sign 14 is allowed to be illuminated at a time. Raise the warning light and point the illuminated side towards the vehicle that needs to be directed. The vehicle indicated by the illuminated character 12 should either wait, stop, or proceed. This improves the effectiveness of traffic control. It achieves the dual function of "light warning + illuminated character 12 signal indication", retaining the advantages of strong light warning at night, and intuitively conveying traffic instructions through the illuminated characters 12. This solves the problem of inefficient traffic control caused by poor lighting or misunderstanding of gestures, significantly improving the efficiency of traffic accident prevention and traffic management.

[0022] Furthermore, such as Figures 3-6 As shown, this is the first embodiment of the present invention. The sign 14 can be installed around the outside of the transparent lampshade 6 along the axis of the transparent lampshade 6. In order to facilitate the viewing of pedestrians and drivers, the sign 14 is installed on the upper part of the transparent lampshade 6, that is, the upper two-thirds of the red area. This area is the core area where the driver's line of sight is focused and will not block the light emission of the transparent lampshade 6.

[0023] Furthermore, such as Figures 7-9 As shown, this is the second embodiment of the present invention. The aforementioned sign 14 can be linearly arranged and installed on the outside of the transparent lampshade 6 along a direction parallel to the axis of the transparent lampshade 6. The display surfaces of the illuminated characters 12 of all the sign 14 face the same direction. Unlike the first embodiment, the illuminated sign 14 can be accurately aligned with the vehicle to be directed without rotating the handle 5, solving the problem that traditional wraparound sign 14 requires frequent rotation of the handle 5 to adjust the direction. Especially in scenarios with dense traffic and the need to quickly switch the target of the direction, it significantly shortens the instruction transmission time and reduces the workload of traffic police. The uniform orientation design ensures that the instruction signal is only transmitted to the target vehicle, avoiding interference with vehicles in other directions and reducing the risk of traffic chaos. It is especially suitable for scenarios requiring directional direction control, such as one-way lanes and tunnel entrances.

[0024] Furthermore, such asFigures 1-2As shown, in addition to assisting traffic police in confirming whether the current operation is correct (avoiding accidental touches leading to incorrect commands), a speaker 15 is also installed on the handle 5. The speaker 15 is used to broadcast the voice corresponding to the current working status of the sign 14. Several sound holes are opened at the end of the handle 5 near the lamp holder 9. The speaker 15 is installed inside the handle 5 at the position corresponding to the sound holes. The addition of the speaker 15 realizes dual prompts of "visual (illuminated character 12) + auditory (voice)". The voice content is precisely matched with the command of the illuminated character 12. For example, when the "stop" character is illuminated, it corresponds to the voice broadcast of "please stop"; when the "wait" character is illuminated, it corresponds to the voice broadcast of "please wait"; and when the "go" character is illuminated, it corresponds to the voice broadcast of "normal driving". To facilitate driver understanding of different illuminated signs, "Stop" uses red light, "Go" uses green light, and "Wait" uses yellow light, consistent with common traffic light colors. This assists traffic police in confirming the correctness of their actions and provides additional guidance for drivers with normal hearing. It is particularly suitable for noisy environments (such as heavy traffic noise and frequent honking), improving the accuracy of instruction reception. The speaker 15 has a power and frequency response range of 200-5000Hz, suitable for outdoor scenarios, ensuring clear voice transmission without producing harsh noise. The sound outlets (diameter 1.5-2mm, spacing 3-5mm) are arranged in a circular array, combined with a metal dustproof mesh (to prevent foreign object intrusion), protecting the speaker 15 while ensuring sound quality and extending its service life. Voice prompts eliminate the need for traffic police to shout, reducing their physical exertion. It also helps all drivers, except those with hearing impairments, to quickly understand instructions, reducing misunderstandings caused by language barriers and environmental noise, and improving traffic management efficiency. In addition, the control circuit board 8 also integrates a main control chip (model STM32F030C8T6), a power management module (output voltage 3.3V / 5V), and a drive module (using a MOS transistor drive circuit). The main control chip is used to receive the operation signals of the function button 4 and control the working status of the white bulb 10, the indicator 14, and the speaker 15. The handle 5 is also equipped with a rechargeable lithium battery (capacity ≥2000mAh, nominal voltage 3.7V). The lithium battery is electrically connected to the power management module to provide working power 7 for the entire warning light. The handle 5 has a Type-C charging interface on its side, which is electrically connected to the power management module, and the outside of the charging interface is equipped with a silicone dust plug. The main control chip (STM32F030C8T6) has high-performance data processing capabilities and can accurately identify the operation of function button 4 (such as short press and long press). Combined with the power management module 7 (stable output of 3.3V / 5V) and the MOSFET driver module (adapting to the current requirements of light bulbs / illuminated signs 12), it avoids equipment failure caused by circuit voltage fluctuations, ensures the accuracy and stability of command execution, and reduces command interruptions caused by circuit problems.A rechargeable lithium battery (3.7V) with a capacity of 2000mAh or higher supports continuous operation for 8-12 hours (based on intermittent use), meeting the daily duty needs of traffic police. The Type-C charging interface offers strong compatibility (compatible with mainstream chargers), and the silicone dust plug (with a nylon connecting rope) prevents dust and rain from entering the interface, extending the charging module's lifespan and preventing loss, thus improving convenience for outdoor use. The power management module intelligently allocates current (e.g., prioritizing power for bulbs / illuminated signs, and automatically reducing power consumption for non-core functions when the battery is low). Combined with the high capacity of the lithium battery, this further enhances battery life, reduces the frequency of outdoor charging, and lowers operating costs.
