Abstract

The utility model relates to a fault alarm. The fault alarm is formed by that three sets of light-emitting plates are mutually pivoted by one end to be collected or combined to form a triangular light-emitting alarm; the light-emitting plates adopt a light emitting diode to serve as a light source and adopt an accumulator cell to provide working power supply; the accumulator cell is connected with a solar energy plate through a control circuit to utilize solar energy to charge and supply power. When the fault alarm is used on a rainy day with insufficient light rays or at night and the problem of poor sight lines can exist in other drivers, the fault alarm has the effect of effectively raising alarm to ensure safety; in addition, because energy resource is taken from the solar energy, the use of a dry battery can be reduce to have the concept of economy and environmental protection simultaneously.

Description

The failure warning device

Technical field

The utility model relates to a kind of failure warning device, but particularly relates to a kind of failure light emission attention device that utilizes sun power to power or charge.

Background technology

All must prepare leg-of-mutton attention device on the general automobile,, provide the usefulness of back car caution, avoid overtaking collision to meet accident so that after when automobile casts anchor, placing car temporarily.Failure warning device in one's early years is to adopt the reflecting type design, and meaning is that its caution message comes from produce behind the back car car light irradiation attention device reflective, and there is parameter naturally in its warning safe.For this reason, the initiatively attention device appearance of light source of tool is arranged, because the failure warning device is the suitable distance in rear that places the vehicle that casts anchor, so the working power great majority of a bright light source are to be supplied by the dry cell that not pulled strings by power lead, but the consumption of dry cell not only causes extra expense, simultaneously the discarded environmental issue that also causes of battery.

This shows that above-mentioned existing fault attention device obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that attention device exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of failure warning device of new structure, just become the current industry utmost point to need improved target.

Because the defective that above-mentioned existing fault attention device exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of failure warning device of new structure, can improve general existing fault attention device, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.

Summary of the invention

The purpose of this utility model is, overcome the defective that the existing fault attention device exists, and provide a kind of failure warning device of new structure, technical matters to be solved provides a kind of illuminated failure warning device that can be powered or be charged by sun power, but it has not only kept the initiatively advantage of light source of failure light emission caution utensil, and because of using reusable solar energy charging battery, thus can reduce expense effectively, avoid causing environmental issue, thus be suitable for practicality more.

Though the initiatively failure warning device of light source of tool is arranged at present, and economic environmental protection to the greatest extent not yet needs to be further reviewed improvement, and seeks feasible solution on the acquisition mode of power source.

For reaching the major technique means that aforementioned purpose takes is to make aforementioned failure warning device include: a foldable attention device, form by most luminous plaques, set up reflecting piece and light emitting diode in the luminous plaque separately, the light emitting diode in each luminous plaque also interconnects; One control circuit, be to be located on the aforementioned attention device, it has a charge circuit and a light-operated loop at least, and wherein charge circuit is provided with accumulator, it is connected with each light emitting diode on the aforementioned attention device by light-operated loop, with supply its when luminous the palpus working power; One solar panels are that the charge circuit by aforementioned control circuit is connected with its accumulator, so that accumulator is charged.
