Description

Emergency brake warning indicator

Technical Field

The utility model belongs to the motorcycle field, concretely relates to emergency brake attention device.

Background

When the motorcycle brakes in the running process, the brake lamp can be lightened to inform that the rear vehicle brakes; but does not tell whether the rear vehicle is in an emergency brake state. Therefore, the brake warning indicator is arranged at the rear part of the vehicle, so that the brake lamp is constantly on when the brake is normally performed, but when the brake is suddenly stepped on, the brake lamp can twinkle, and the occurrence of accidents can be better prevented after the vehicle is warned better at the moment.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in figure 1: an emergency alert device, comprising: the brake control device comprises a voltage conversion module, a brake signal input module, a rotating speed input module, a control module and an output module;

Further, the voltage conversion module comprises a chip LM317 BZG.

The specific embodiment is as follows:

as shown in figure 1: in the running process of the locomotive, when a brake signal is a brake signal, 12V voltage is input to the BRAK end, and when the brake signal is not braked, the BRAK end is grounded, namely a 0V signal is input to the BRAK end. The wheel SPEED signal is a Hall signal at a wheel, the wheel can provide a 5V high potential for a SPEED end when rotating a circle, a Hall magnetic block is usually arranged at the wheel, a Hall element is arranged on a vehicle body near the wheel, when the wheel rotates a circle, the wheel can be close to and far away from the Hall element once, the Hall element can be opened when the wheel is close to, a 5V high potential is provided for an SPPED end, the Hall element can be closed when the wheel is far away from, a 0V low potential is provided for the SPEED end, the voltage conversion frequency exists at the moment, and the voltage change at the SPPED end is transmitted to a 3 rd pin of a control chip U3 after being transmitted to a signal amplification circuit. When the 2 nd pin of the control chip U3 is used as both input and output, when the 2 nd pin detects that the brake signal input is high and the SPEED end is in rapid deceleration, the 2 nd pin outputs 4HZ square wave to make the transistor Q3 open and close at the frequency of 4Hz, so that the relay J1 opens and closes at the frequency of 4Hz, and the voltage of the storage battery is output from the OUT end at the frequency of 4Hz (OUT is connected with the brake lamp), so that the brake lamp flickers.

When generally not slowing down, the 2 nd foot only does the input, and during the brake, the triode Q3 is opened to the 12V voltage that produces during the brake can pass through R5, D2, R8, R13 among the signal partial pressure current-limiting circuit for relay J1 opens, and OUT end output lights the stoplight, and the benefit of doing so is that even U3 damages, the sudden braking scintillation function does not do, can not influence the bright function of stoplight when normally braking yet.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
