Description

Technical Field

[0001] This utility model belongs to the field of automotive active safety technology, and more specifically, it relates to a safety headlight that automatically triggers a red warning light when the distance to another vehicle is too close. Background Technology

[0002] Vehicle safety headlights are an important component of an automotive active safety system. Their core positioning is "based on illumination, with safety warnings / alerts as the core"—unlike traditional headlights that only meet the needs of nighttime illumination, they integrate mechanical structures, electronic sensors, or intelligent control technologies to actively transmit the vehicle's driving status (such as close following distance, braking, steering) and warn of potential dangers while fulfilling basic lighting functions. This helps the driver clearly perceive road conditions and allows surrounding vehicles / pedestrians to recognize the vehicle's intentions in advance, reducing the risk of collision accidents from the source.

[0003] From a manufacturing perspective, current mainstream vehicle distance warning systems heavily rely on multi-sensor fusion solutions. The high cost of core components such as lidar and millimeter-wave radar makes them difficult to integrate into mid-to-low-end models, limiting the technology's widespread adoption. At the same time, integrating sensors with the headlight system requires the additional development of adaptation circuits and control modules, increasing the complexity of the production line. Public data from a certain automaker shows that the production and assembly time for such integrated solutions is longer than that of traditional headlights, significantly increasing manufacturing costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a safety headlight that automatically triggers a red warning light when the distance to the vehicle is too close, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a safety headlight that automatically triggers a red warning light when the distance to another vehicle is too close, achieved through the following specific technical means: A safety headlight that automatically triggers a red warning light when the distance to another vehicle is too close includes a headlight, a triggering component, and a red warning light. The triggering component is installed inside the vehicle's grille and opposite the grille's air intake. The red warning light is embedded in one side of the headlight. The triggering component includes a cup shaft that rotatably passes through the inside of the vehicle's grille. The top outer wall of the cup shaft is rotatably fitted with a mounting sleeve via a bearing. The outer wall of the mounting sleeve is detachably fitted with multiple sets of cup flaps via a tightening threaded ring. A reciprocating slide rod that can cooperate with the multiple sets of cup flaps is slidably installed on the side wall of the headlight. An L-shaped shield and a second spring are sequentially fitted on the outer wall of the reciprocating slide rod. One end of the shield is connected to a flashing component for flashing the red warning light. A rotational resistance component is provided on the outer wall of the cup shaft.

[0006] Preferably, the flashing component includes a light-transmitting cover and a light-shielding cover spaced apart and installed at one end of the shielding plate, wherein the side of the light-transmitting cover facing the red warning light is provided with a honeycomb-shaped equilateral triangular prism pattern.

[0007] Preferably, the bottom end of the mounting bushing is provided with an internal thread, the inner wall of the clamping threaded ring is provided with an internal thread, the clamping threaded ring and the clamping threaded ring are spirally connected, and the top end of the clamping threaded ring is provided with a dust cover for protecting the bearing, the dust cover being a sealing cover plate structure.

[0008] Preferably, the rotational resistance assembly includes a first spring fitted onto the outer wall of the wind cup shaft. The two ends of the first spring are respectively provided with a second abutting ring and a first abutting ring. The second abutting ring and the first abutting ring are slidably connected to and fixedly connected to the outer wall of the wind cup shaft, respectively. A protruding post is provided on the top side of the second abutting ring, and a triangular abutting block is provided on the bottom side of the mounting sleeve. The side wall of the abutting block abuts against the top side of the protruding post.

[0009] Preferably, a white laser engraving line is provided on the side of the outer wall of the mounting bushing near the wind cup petal. The engraving line is 1cm long and 0.1mm wide, which is used to align with the vertical grid strips of the grille, quickly calibrate the facing angle between the wind cup petal and the air inlet, and shorten the installation and adjustment time.

[0010] Preferably, the prism pattern surface of the shielding sheet is coated with a 5μm thick wear-resistant transparent coating made of polydimethylsiloxane to reduce the wear of the prism pattern caused by dust friction.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses the wind cup flap in conjunction with the air inlet of the vehicle's grille to achieve sensitivity only to oblique vortices when the distance between vehicles is too close, and no response to high-speed forward natural wind. This avoids false triggering caused by high-speed natural wind from the source, ensuring that the triggering component only operates at dangerous distances and improving warning accuracy. By using the wind cup shaft in conjunction with the rotational resistance components (first spring, first retaining ring, second retaining ring, protrusion, retaining block), the triggering resistance is adjusted according to the wind cup rotation speed (corresponding to the distance between vehicles). The reciprocating slide bar is only pushed when the wind cup rotation speed reaches the dangerous distance threshold, avoiding false triggering caused by low-speed bumps and slight airflow, strengthening the anti-false triggering effect, and adapting to the safety warning needs at different vehicle speeds.

[0012] 2. This utility model uses a reciprocating slide bar in conjunction with a shielding plate and a second spring to achieve stable reciprocating movement of the shielding plate along the light path, causing the light-transmitting cover and the light-shielding cover to alternately block the red warning light, ensuring that the flashing frequency of the red warning light is uniform, avoiding flashing jams or frequency disorders, and improving the recognition efficiency of following vehicles; by using the shielding plate (the honeycomb-shaped equilateral triangular prism pattern of the light-transmitting cover) in conjunction with the red warning light, the red warning light light is refracted into a parallel beam, which greatly improves the light penetration in rainy and foggy weather and solves the pain point of the warning effect attenuation under bad weather.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a safety headlight that automatically triggers a red warning light when the distance to another vehicle is too close. It includes a headlight 1, a triggering component 3, and a red warning light 4. The triggering component 3 is installed inside the grille of the vehicle's center grille 2 and opposite to the air inlet of the grille. The red warning light 4 is embedded in one side of the headlight 1. The triggering component 3 includes a wind cup shaft 301 that is rotatably inserted inside the grille of the vehicle's center grille 2. The top outer wall of the wind cup shaft 301 is rotatably fitted with a mounting sleeve 306 via a bearing. The outer wall of the mounting sleeve 306 is detachably fitted with multiple sets of wind cup petals 309 via a pressing threaded ring 307. The side wall of the headlight 1 is slidably fitted with a reciprocating slide rod 310 that can cooperate with the multiple sets of wind cup petals 309. The outer wall of the reciprocating slide rod 310 is fitted with an L-shaped shielding plate 312 and a second spring 311 in sequence. One end of the shielding plate 312 is connected to a flashing component for making the red warning light 4 flash. The outer wall of the wind cup shaft 301 is provided with a rotational resistance component.

[0019] The flashing component includes a light-transmitting cover 313 and a light-shielding cover 314 spaced apart and installed at one end of the shielding plate 312. The side of the light-transmitting cover 313 facing the red warning light 4 has a honeycomb-shaped equilateral triangular prism pattern, which solves the problem that the warning light is easily blocked in rainy, foggy, or strong light conditions at night. The visibility distance of the red warning light 4 to the following vehicle is extended from 20 meters of traditional diffused light to more than 60 meters, allowing more reaction time for the following vehicle. The prism pattern only acts on light refraction and does not change the sliding fit property of the shielding plate 312, ensuring that the flashing component can still smoothly switch the light path when linked with the reciprocating slide bar 310, without affecting the stability of the flashing frequency of the red warning light 4.

[0020] The mounting sleeve 306 has an internal thread at its bottom end, and the inner wall of the clamping threaded ring 307 has an internal thread. The clamping threaded ring 307 and the clamping threaded ring 308 are spirally connected. The top of the clamping threaded ring 307 is equipped with a dust cover 308 for protecting the bearing. The dust cover 308 is a sealing cover plate structure. The spiral connection between the mounting sleeve 306 and the clamping threaded ring 307 is achieved by matching the internal thread at the bottom end of the mounting sleeve 306 with the internal thread on the inner wall of the clamping threaded ring 307, realizing "rotation and tightening fixation". Compared with the traditional snap-fit ​​fixation, the connection strength is increased by 40%, and the disassembly is better. When it is necessary to replace the wind cup 309 or clean the inside in the future, it can be disassembled by simply loosening the clamping threaded ring 307 without damaging the grid structure, thus reducing the difficulty of maintenance. The dust cover 308 provides sealing protection: The dust cover 308, with its sealing cover plate structure, is installed on the top of the tightening threaded ring 307. It can completely cover the bearing gap between the mounting bushing 306 and the wind cup shaft 301, effectively blocking sand and rainwater sucked in by the grille air inlet from entering the bearing. This prevents the bearing from experiencing increased rotational resistance due to foreign objects getting stuck or corrosion, extending the service life of the wind cup shaft 301 from 2 years to 5 years.

[0021] The rotational resistance component includes a first spring 303 fitted onto the outer wall of the wind cup shaft 301. A second abutting ring 304 and a first abutting ring 302 are respectively abutted at both ends of the first spring 303. The second abutting ring 304 and the first abutting ring 302 are slidably connected to and fixedly connected to the outer wall of the wind cup shaft 301. A protruding post 305 is provided on the top side of the second abutting ring 304, and a triangular abutting block 315 is provided on the bottom side of the mounting sleeve 306. The side wall of the abutting block 315 abuts against the top side of the protruding post 305. The graded resistance control prevents accidental activation: the first spring 303 provides basic resistance; the fixed first abutting ring 302 and sliding second abutting ring 304 work together to ensure that the second abutting ring 304 can overcome the spring force and move the protruding post 305 only when the wind cup shaft 301 reaches a specific speed. This avoids accidental activation in non-dangerous scenarios such as low-speed bumps and slight crosswinds, thus improving the accidental activation rate. Precise transmission of the triangular abutment block 315: The triangular abutment block 315 and the top side of the protrusion 305 are tightly fitted together. Compared with the flat contact, the contact point is more stable. It can accurately convert the rotational power of the wind cup shaft 301 into the axial thrust of the reciprocating slide rod 310, avoid transmission jamming caused by contact offset, ensure the consistency of the sliding stroke of the shield 312, and make the flashing frequency of the warning light stable.

[0022] The outer wall of the mounting bushing 306, near the wind cup 309, has a white laser-etched line, 1cm long and 0.1mm wide, used to align with the vertical grille bars. This allows for quick calibration of the angle between the wind cup 309 and the air inlet, shortening installation and adjustment time. Traditional installation requires repeated attempts to rotate the wind cup 309 and observe the airflow response, taking up to 5 minutes to adjust. The etched line alignment design allows for visual alignment of the etched line with the grille bars during installation, completing the angle calibration of the wind cup 309 and the air inlet in just 30 seconds. This significantly lowers the installation threshold for ordinary users, requiring no professional tools or maintenance experience.

[0023] Among them, the prism texture surface of the shielding plate 312 is coated with a 5μm thick wear-resistant transparent coating. The coating material is polydimethylsiloxane, which is used to reduce the wear of the prism texture by dust friction.

[0024] The working principle of this embodiment is as follows: During installation, first align the white laser-etched lines of the mounting bushing 306 with the vertical grille bars of the grille, quickly calibrate the facing angle between the wind cup petal 309 and the air inlet of the grille, and install it inside the grille of the vehicle's center grille 2. Then, fix the wind cup petal 309 by tightening the threaded ring 307 and the spiral connection between the mounting bushing 306 and the dust cover 308 to protect the bearing. When the distance between this vehicle and the vehicle in front is too close, the oblique vortex generated at the bottom of the vehicle in front blows towards the wind cup petal 309 through the air inlet of the grille, causing the wind cup shaft 301 to rotate around the bearing inside the mounting bushing 306. During the rotation of the wind cup shaft 301, the first spring 303 of its outer wall rotation resistance component is compressed, and the second abutment ring 304, which is slidably connected to the wind cup shaft 301, moves upward accordingly, causing the top side of the second abutment ring 304 to... The protruding post 305 abuts against the abutting block 315 on the bottom side of the mounting bushing 306, thereby pushing the reciprocating slide rod 310 to slide along the side wall of the headlight. When the reciprocating slide rod 310 slides, it drives the shielding plate 312 to move synchronously. The light-transmitting cover 313 at one end of the shielding plate 312 facing the red warning light 4 has a honeycomb-shaped equilateral triangular prism pattern and the light shielding cover 314 alternately act on the light path of the red warning light 4, so that the red warning light 4 flashes. When the distance between vehicles returns to a safe range, the eddy current of the vehicle in front disappears, the wind cup shaft 301 stops rotating, the first spring 303 resets and drives the second abutting ring 304 and the protruding post 305 to return to their original positions. The second spring 311 pulls the reciprocating slide rod 310 and the shielding plate 312 to reset. The light-transmitting cover 313 and the light shielding cover 314 stop blocking the light path, and the red warning light 4 returns to its initial state.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
