Abstract

A safety system for alerting a speed of a vehicle, comprises the rotary unit; the elastic element having one end engaged to the rotary unit; a side of the base having a via hole; the base having a groove; the rotary unit being placed upon the groove of the base; the control circuit board seat connected to a brake bulb and a power plug; a switch of the control circuit board seat being inserted into the base and the rotary unit; a plurality of studs serving to lock the control circuit board seat to the base; the rotary unit being wound with a connecting wire which passes through the via hole; the outer cover being fixed upon an upper side of the groove of the base by using screws so as to seal the groove.

Claims

1. A safety system for alerting a speed of a vehicle, comprising:

a rotary unit;

an elastic element having one end engaged to the rotary unit;

a base, a side of the base having a via hole;

the base having a groove;

the rotary unit being placed upon the groove of the base;

a control circuit board seat connected to a brake bulb and a power plug;

a switch of the control circuit board seat being inserted into the base and the rotary unit;

a plurality of studs serving to lock the control circuit board seat to the base;

the rotary unit being wound with a connecting wire which passes through the via hole;

an outer cover being fixed upon an upper side of the groove of the base by using screws so as to seal the groove;

wherein the connecting wire winds around the rotary unit and is connected to the actuated switch and then is connected to a throttle pedal or an acceleration rope in the engine chamber;

the control circuit board seat is connected to a power source;

when the connecting wire is pulled and then returned, the rotary unit will control the actuation switch, and the elastic element will generate a resilient force due to rotation so that the connecting wire will return automatically to drive the switch of the control circuit board seat to generate control signals;

the control circuit board seat controls the brake bulb to flash;

a driver at a front car will release the throttle pedal to make a control box to cause the rear light to flash;

thus the driver of the rear car has a longer reaction time for braking.

2. The safety system for alerting a speed of a vehicle as claimed in claim 1, wherein the elastic element is one of a spring and a gear set.

3. The safety system for alerting a speed of a vehicle as claimed in claim 1, wherein the control circuit board seat is connected to an alarm light for a vehicle.

4. The safety system for alerting a speed of a vehicle as claimed in claim 1, wherein the rotary unit has a post;

the elastic element has one end engaged to the trench of the post of the rotary unit;

in the groove of the base has a bar for connecting another end of the elastic element.

5. The safety system for alerting a speed of a vehicle as claimed in claim 1, wherein the rotary unit is formed with a recess;

the base is formed with a through hole corresponding to the recess of the rotary unit for combining the control circuit board seat to the rotary unit and the base.
