Description

Built-in helmet warning device

The utility model relates to an embedded safety helmet warning device, in particular to a warning strip embedded around the outer shell of the safety helmet, so as to trigger the warning lights of the warning strip and send out warning lights. To improve the safety of motorcyclists riding motorcycles at night.

At present, motor vehicles have become a means of transportation for many people, and the design of the current locomotive is equipped with a brake light at its rear. When braking or turning on the headlights, the brake lights at the rear will be lit to warn of vehicles coming from behind. However, due to the extremely low position of the brake lights of general motorcycles, if the motorcycle rider is riding at night and wears dark clothing such as black, it will often be overlooked by other drivers or pedestrians in the rear or other directions. Lose its warning effect, produce traffic accidents such as chasing and colliding to take place.

Therefore, existing industry has developed a kind of safety helmet with flashing warning light, and this safety helmet comprises: a safety helmet cap body, and it has a hard casing, and this hard casing has an inner side and an outer side, and its inner side is fixed with a The protective cushion layer has a groove; a control switch is placed in the groove of the protective cushion layer. The control switch has a switch body with a button below the switch body and a button below the button. connecting piece; and a flash lamp holder fixed on the outside of the hard shell, the flash lamp holder includes a flash lamp group and a DC power supply, the DC power supply is electrically connected to the flash lamp group through the control switch; When wearing a safety helmet, the connecting piece is pushed on the top of the head, so that the connecting piece presses the button below the switch body upwards, and the special control switch is activated to make the flashing light group send a flashing signal.

The above-mentioned helmet structure still has the following disadvantages in use:

1. The connecting piece must be pushed on the top of the head to operate and start the power supply. When the user uses it for a long time, he will feel that there are foreign objects pressing on the top of the head, which is extremely uncomfortable.

2. The flash lamp holder protrudes outside the hard shell of the safety helmet, making the safety helmet extremely abrupt and unattractive.

3. The flash of the flash lamp holder can only be emitted outward in one direction. Therefore, it only provides a warning function in one direction, and the warning effect is relatively incomplete.

The purpose of this utility model is to provide a built-in safety helmet warning device. A warning strip is firmly nested in the outer shell of the safety helmet, and a plurality of warning lights are arranged in the warning strip, so that each warning light A control circuit operates to trigger lights to flash, so that warning lights can be sent out around the safety helmet to warn other drivers and improve the safety of users riding motorcycles at night.

The purpose of this utility model is achieved in this way: a built-in safety helmet warning device has an outer shell of the safety helmet, and is characterized in that a warning strip is firmly nested around the outer shell of the safety helmet, and A plurality of warning lights are arranged in the warning strip, and the plurality of warning lights are connected with a control circuit.

The warning strip includes a flexible transparent strip body, and is fitly embedded in a groove around the outer shell of the safety helmet; the plurality of warning lights are installed in the flexible strip body; and the The control circuit includes a box body fixed on the bottom edge of the safety helmet, and a circuit board is fixedly installed in the box body to connect the first and second terminals of each warning light.

The circuit board in the control circuit contains a flashing circuit.

The control circuit includes a photoresistor.

By adopting the above scheme: improve the safety of the user riding a locomotive at night.

It can be clarified from the following description and the accompanying drawings.

Fig. 1 is a three-dimensional schematic diagram of the utility model.

Fig. 2 is a schematic top view of the utility model.

Fig. 3 is a schematic diagram of the warning strip of the present invention.

Fig. 4 is a schematic cross-sectional view of the utility model.

Fig. 5 is a schematic diagram of the control circuit without a photoresistor of the utility model.

Please refer to Fig. 1-4, the utility model relates to a built-in safety helmet warning device, a warning strip 2 is firmly nested in the outer shell 11 of the safety helmet 1, and the warning strip 2 is set There are a plurality of warning lights 22, each of which is triggered by a control circuit 23 to flash, so that warning lights can be sent out around the helmet 1 to warn other drivers and improve the user's ability to ride at night. car safety.

The safety helmet 1 disclosed by the utility model includes an outer shell 11, and an inner liner 12 is connected to the part of the outer shell 11; wherein a groove 111 is recessed on the outer edge of the outer shell 11 to stably insert Establish a warning strip 2 in the inner circumference.

The appearance of the safety helmet 1 disclosed by the utility model can be a full-face helmet or a half-face helmet as shown in FIG. 1 , and the utility model is not limited by itself.

The warning strip 2 disclosed by the utility model includes: a flexible strip 21 can be taken from transparent strips such as silicone, rubber, gum, plastic, etc., so as to be fitted in the groove on the periphery of the helmet shell Among them; a plurality of warning lights 22, which can be taken from light-emitting diodes, are installed in the flexible belt body 21; and a control circuit 23 contains a box body 231 fixed on the bottom edge of the safety helmet 1, in the box A circuit board 232 is fixedly installed in the body 231 to connect the first and second extremes of each warning light 22, and a switch 233 is installed on the circuit board 232 to control the power supply opening and closing of the control circuit 23, as shown in Figure 5 As shown, insert a 3V battery (DC), turn on the switch (sw) to conduct the current, and the current passes through the IC through the current limiting resistor 120 ohms (R1), causing the LED to flicker.

In the above-mentioned control circuit 23, the circuit board 232 can be a flashing circuit, so that after the switch 233 is switched, each of the warning lights 22 is triggered to be in a flashing state, and the flashing method is not self-limited by the present invention; The switch 233 disclosed by the utility model can be a general toggle switch or a photoresistor can be added to make the photoresistor turn off the power supply in a bright environment and turn off the power supply in a dark environment. A closed circuit (on) makes the utility model automatically trigger each of the warning lamps 22 to project light outwards in a dark environment (such as at night or when entering a tunnel) for warning, and in a bright environment (such as during the day or when going out of a tunnel) Can cut off this power supply automatically, stop flashing each this warning light 22.

The warning strip 2 disclosed in the utility model is arranged around the outer shell 11 of the safety helmet 1, and each warning light 22 is correspondingly arranged around the safety helmet 1, so after starting and flashing, you can The front, rear, left, and right directions are respectively projected for warning, so as to warn other drivers in an all-round way, which can effectively improve the driving safety of motorcyclists in dark environments, and demonstrate the practicability and novelty of the utility model.
