Description

Vehicle fault warning light

This creation department is concerned with a fault warning sign, especially a vehicle fault warning sign that can actively emit light.

Press, when the vehicle is forced to stop on the road during the travel, usually a vehicle fault warning sign (or triangle warning sign) is required behind the vehicle to remind and warn other vehicles, please refer to the first As shown in the figure, the conventional vehicle fault warning sign 1 uses the reflector 11 to reflect the outside or the car light line to achieve the warning effect, and the remaining detailed structure of the vehicle fault warning sign 1 is a person skilled in the art. It is well known and will not be described here.

The conventional vehicle fault warning sign 1 has only passive reflective structure and the warning effect is poor. Therefore, the industry has improved it and introduced a fault warning sign (also called a fault warning light) with a light source such as an LED lamp, such as the Republic of China patent. Bulletin No. M259976 "Improvement of the structure of the vehicle triangle warning device" and the patent document No. I413948 "Traffic warning device with direct methanol fuel cell", but the above-mentioned technical premise can actively emit light to improve the warning effect, but There are still some improvements worthy of improvement: First, the existing fault warning signs, whether or not they have active illumination, are mostly composed of two tripods 12 that are shallow and shaped and connected to each other. As shown in the first figure, when the two legs 12 are opened, a cross shape is formed and only four support points are formed, resulting in poor stability of the support and being easily dumped by external forces (such as wind); secondly, The electronic control module such as the circuit board and the battery are not placed at the lowest point of the entire fault warning sign, and the weight of the product is not further optimized for the stability requirement; finally, the circuit of the circuit board is mainly composed of individual transistors. The combination of discrete components such as diodes and capacitors results in a complicated circuit layout, and the size and power consumption of the circuit are large, so that the power supply voltage required to drive the circuit is relatively high, usually about 4.5V (equivalent to three). The dry battery is connected in series), which improves the power supply cost of the conventional fault warning sign. Therefore, how to improve the above-mentioned defects is the technical difficulty point that the applicant of the case wants to solve.

In view of the conventional fault warning signs, the number of support points formed by the support frame is small, and the overall weight is not optimized, resulting in poor stability of the support, easy dumping, and the circuit of the circuit board is discrete. The electronic component is composed of a large power supply voltage or a large battery to drive the power supply cost. Therefore, the purpose of this creation is to develop a vehicle fault warning sign that can improve the stability of the support and reduce the power supply cost. .

In order to achieve the above purpose, the present invention provides a vehicle fault warning light, comprising: a warning sign component, and a first warning board, a second warning board and a third warning board sequentially connected, each of the warning boards There are a plurality of LED lights respectively; a support frame assembly is disposed under the warning sign assembly, and the support frame assembly is provided with three tripods which are vertically stacked from top to bottom and are mutually coupled; a power module is arranged Below the support frame assembly, a power supply and a control circuit board electrically connected to the power supply are disposed in the power module, and the control circuit board is also electrically connected to each LED lamp.

In this way, the creation of the tripod can display a total of six support points in the shape of a meter, and the overall weight can be optimized for stability requirements, avoiding top-heavy weights. High support stability to avoid or reduce the warning signs being blown down or even damaged by the wind, so that the creation can greatly improve the reliability and service life of the product.

Referring to the second figure, the present invention provides a vehicle fault warning light, comprising: a warning sign component 3, the warning sign component 3 is provided with a first warning board 31 and a second warning board 32 connected in sequence. And a third warning board 33. Generally, the two ends of the second warning board 32 are respectively pivoted with one end of the first warning board 31 and one end of the third warning board 33. The other end of the first warning board 31 and the third warning board 33 The other end is detachably combined, and can be combined into a triangular warning sign structure when needed. The above is a typical or conventional structural configuration of the triangular warning sign, and each of the warning boards is respectively provided with a plurality of The LED lamp 34, and each of the warning plates is respectively provided with a transparent cover 35 for enclosing the LED lamps 34, so that the light of the LED lamps 34 can be emitted outward, and the LED lamp 34 can be provided with waterproof and dustproof In addition, the protection component, in addition, the other detailed structure of the warning sign component 3 or each of the warning boards are prior art and not technical features of the present invention, and will not be described herein; a support frame assembly 4, the support frame assembly 4 is set in the warning Below the card assembly 3, the support frame set 4 is provided with three sequentially stacked from top to bottom and provided each shaft stand 41 contact to enabling the three- The power stand 5 is disposed under the support frame assembly 4, specifically, the power module 5 is configured to be rotated in a m-shaped manner, as shown in the second figure.
