Description
Technical Field
[0001] This utility model relates to a driving safety warning device, and more particularly to a multifunctional driving safety warning device implemented through mechanical structure and electronic technology. Background Technology
[0002] When driving, safety is always the top priority. Besides passive safety measures like seat belts and airbags, active safety devices are equally important, such as the safety triangle. It may seem insignificant, made of reflective plastic with a reflective triangle on the outside and a fluorescent triangle in the middle, connected to a base. However, it provides crucial safety protection in the event of a vehicle malfunction or accident, effectively preventing secondary accidents.
[0003] A car safety triangle is an important piece of equipment for traffic safety, especially in the event of a vehicle breakdown or accident. Its usage guidelines include:
[0004] On highways, safety triangles should be placed 150 to 250 meters behind the vehicle during the day and even further away at night to ensure sufficient reaction time for following vehicles. On ordinary urban roads, they should be placed 50 to 100 meters behind the vehicle during the day and 80 to 100 meters behind at night. In rainy or foggy weather, the placement distance of the safety triangle should be increased due to reduced visibility.
[0005] While traditional safety tripods can serve a certain warning purpose, they also have some shortcomings in practical use:
[0006] The reflective effect is poor, especially in rainy, foggy weather or at night when the light is insufficient, the reflective effect of the safety triangle will be greatly reduced, making it difficult to attract the attention of vehicles behind; it is easily knocked over or blown away: due to its light weight, the safety triangle is easily blown over by the airflow or collision of oncoming vehicles, losing its warning function; the safety triangle is placed on the ground at a low height, making it difficult for vehicles at a distance to see it in time, leading to secondary accidents; the process of placing the safety triangle on foot is also relatively dangerous, often resulting in insufficient placement distance.
[0007] To address the aforementioned product defects, this utility model proposes a novel driving safety device. Utilizing a special mechanical structure design and electronic technology, the device maintains portability for storage and use, making it easy to carry in the vehicle and access at any time. It can also be attached to the roof of the vehicle or move to a sufficient distance for automatic deployment, avoiding the incidental dangers associated with manual placement. Utility Model Content
[0008] This utility model proposes a driving safety warning device, which includes a flat rectangular outer shell A0. A first groove C1 is formed on the upper surface of the outer shell, which houses two sets of warning frame components, A and B, after folding.

[0010] The starting ends of the warning strips A1 and B1 are fixed to the bottom of the first groove C1 by a base Z1 with an angled positioning hinge.
[0011] The angle positioning hinge includes a positioning and locking structure, which includes a spring and ball structure or a ratchet structure.
[0012] The embedded drive wheel L1 is installed inside the outer shell body A0 and is driven by a motor; the auxiliary rolling wheel L2 is fixed in the third groove at the bottom of the outer shell body A0 by a base and a rotating shaft.
[0013] The warning strip frames A1, A2, A3, A4 and B1, B2, B3, B4 are rotated sequentially to the locking angle to form a vehicle warning triangle; each warning strip frame has an LED light strip composed of high-brightness LED beads installed on its front surface.

[0016] Other features and advantages of this utility model will become clearer after reading the detailed description of the embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description
[0017] To clearly illustrate the technical solution and embodiments of this utility model, the accompanying drawings are briefly described below. It should be noted that the drawings are primarily intended to explain the interconnections, structural features, and advantages of the various components of the device, and are not drawn to scale according to the actual dimensions of the device. Obviously, the drawings only relate to a limited set of embodiments and should not be construed as limiting the present utility model. Those skilled in the art can easily obtain new embodiments through formal variations based on these drawings.

[0020] Figure 3 This is a schematic diagram of the bottom structure of one embodiment of the present invention. Detailed Implementation
[0021] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0022] This utility model proposes a driving safety warning device, the shape of which is as follows: Figure 1As shown. The driving safety warning device includes a main body A0, which is flat and rectangular in shape. A first groove C1 is formed on its upper surface to accommodate two sets of warning frame components, A and B, after folding. The A set of warning frame components includes warning strip frames A1, A2, A3, and A4 connected sequentially by a hinge structure; the B set of warning frame components includes warning strip frames B1, B2, B3, and B4 connected sequentially by a hinge structure. The hinge structure is an angle-positioning hinge, designed with positioning and locking mechanisms to ensure that adjacent warning strip frames maintain a stable locked connection at certain set angles. Specifically, the locking angles between warning strip frames A1 and A2 are 0 degrees and 90 degrees, the locking angles between A2 and A3 are 60 degrees and 180 degrees, and the locking angles between A3 and A4 are 0 degrees and 180 degrees. The B set of hinges has similar locking angles, which will not be described in detail. A second groove is also provided on the upper surface of the driving safety warning device, and a cylindrical connector D1 with strong magnetism at both ends is fixedly placed there by a snap ring.
[0023] After pulling the two sets of warning frame components A and B upward from the groove C1, a vehicle warning triangle can be easily assembled by rotating the warning strip frame in sequence. Figure 2 As shown. When A1, A2, A3, and A4 are unfolded, they form the left half of the warning triangle; when B1, B2, B3, and B4 are unfolded, they form the right half. In terms of front-to-back depth, A1 and B1 are side-by-side, A2 is in front of A1, A3 and A4 are side-by-side in front of A2, while B2 is behind B1, and B3 and B4 are side-by-side behind B2. Therefore, there is a spatial distance between A4 and B4 in the front-to-back direction equal to the thickness of the warning strip frame. The ends of A4 and B4 are connected and fixed by the cylindrical connector D1. Both ends are strongly magnetic, and their magnetic poles are attracted to the corresponding ends of the cylindrical connector D1. The starting ends of the warning strip frames A1 and B1 are fixed to the bottom of the first groove C1 by a hinged base Z1, also using an angle-positioning hinge with locking angles of 0 degrees and 90 degrees.
[0024] The angle-positioning hinge uses either a spring and ball mechanism or a ratchet mechanism for positioning and locking. The former has a groove on one component of the hinge, while a spring on the other component holds a ball. When the hinge rotates to a specific angle, the ball engages in the groove, producing a distinct "click" sound and a sense of positioning. Afterward, a certain force is required to overcome the resistance of the ball and continue rotating. This positioning method provides a fixed and clear angle with a strong sense of positioning. The latter uses a gear and pawl mechanism, or a gear-like meshing structure. When the hinge rotates, the gears mesh at a specific angle to achieve angle positioning. This method typically provides a very precise positioning angle and can withstand larger loads.
[0025] LED light strips composed of high-brightness LED beads are installed on the front surface and the left and right side surfaces of the main body A0 of the driving safety warning device. A similar LED light strip composed of high-brightness LED beads is also installed on the front surface of the warning strip frame. When using the driving safety warning device, the built-in main control unit and drive circuit can drive the aforementioned LED light strips to flash rapidly.
[0026] The bottom of the main body A0 of the driving safety warning device is as follows: Figure 3 As shown, an embedded drive wheel L1 is mounted in the middle of its rear section. Its main body is inside the outer casing A0, and it is driven by a motor to move the device back and forth. Four auxiliary rolling wheels L2 are symmetrically mounted near the four corners, fixed to the third groove at the bottom of the outer casing A0 via a base and a rotating shaft. A fourth groove is symmetrically distributed on the inner side of the auxiliary rolling wheels, housing magnetic support feet. One end of each foot is fixed to the fourth groove via a base and a rotating shaft with a locking structure, while the other end is free and has a strong magnetic material on its end face. During use, the foot can be pulled out of the groove until it is perpendicular to the bottom surface of the device and then locked. The locking structure is either a cam structure or a ratchet structure. After the four magnetic support feet are pulled out, the driving safety warning device can be directly attached to the roof or trunk lid for use.
[0027] The driving safety warning device is internally equipped with a control motherboard, a lithium battery, and a drive motor. The control motherboard integrates a main control unit, an LED light strip driver unit, and a lithium battery charging and discharging management circuit. Cable 1 connects to the LED light strips on the front surface and left and right sides of the housing; cable 2 connects to the LED light strips on the front surface of the A group warning strip frame; and cable 3 connects to the LED light strips on the front surface of the B group warning strip frame. A control switch and a charging interface are also installed on the rear side of the driving safety warning device.
[0028] When using the driving safety warning device proposed in this utility model, first pull out the warning strip frame embedded in the upper surface to quickly assemble it into a warning triangle structure and turn on the LED light strip; then, it can be placed on the road facing the direction of oncoming traffic, and the drive motor drives the drive wheel L1 to move it to the designated position automatically; alternatively, the magnetic support feet on the back can be pulled out directly to attach it to the roof of the car or the trunk lid. Therefore, when using this utility model, there is no need to manually place and install the warning triangle against the flow of traffic. The design of its own structure also makes the height of the warning device higher than that of commonly used triangles, which also helps to improve the visibility of the safety triangle and makes it easier for vehicles behind to notice it in time.
[0029] The description of this utility model is given for illustrative purposes only and is not intended to be exhaustive or to limit the utility model to the disclosed forms. The embodiments were chosen and described to better illustrate the principles and practical applications of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose. All new embodiments that fall within the basic concept, construction principles, and spirit of this utility model, and are achieved through simple variations, modifications, equivalent substitutions, or improvements, should be included within the scope of protection of this utility model. The scope of this utility model is defined by the appended claims.
