CN2239167Y - Safety helmet - Google Patents

Abstract

The utility model relates to a safety helmet, particularly a safety helmet with light emitting elements. A plurality of light emitting elements and electric sources are fixed on the hemline of the safety helmet, and the light emitting elements and the electric source are connected by a flasher. The utility model has the advantages that the safety helmet is suitable for students and children walking in the street at daytime, the safety helmet can remind drivers or riders to notice students and children in the street under the condition of poor visibility or at night, and therefore, the students' safety and the children's safety can be ensured.

Description

Safety cap

The utility model relates to a kind of safety cap, particularly a kind of safety cap that has light-emitting component.

The yellow safety cap (small yellow cap) that present pupil generally wears, can remind driver or cyclist to note, guarantee the safety the when pupil walks or goes across the road in the street, but this safety cap only is adapted at wearing daytime, and when causing poor visibility, then do not have warning function at night or because of weather is bad.

The purpose of this utility model is to provide a kind of and not only is suitable for the student, children wear when walking on road daytime, but also the safety cap of wearing when being suitable under the situation of night or poor visibility on road walking.

The technical solution of the utility model is: be fixed with several light-emitting components, power supply on the cap base, be connected by a flasher circuit between light-emitting component and the power supply.Described flasher circuit can adopt the discrete component astable oscillator, also can adopt CMOS integrated circuit or other prior art scheme and circuit.

Advantage of the present utility model is, not only be suitable for the student, children wear when walking on road daytime, but also wear when being suitable under the situation of night or poor visibility on road walking, can remind driver or cyclist to note student, children on the road at any time, thereby better guaranteed the safety that student, children walk on road.

Below in conjunction with drawings and Examples the utility model is done into explanation:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the circuit diagram of the utility model embodiment

Fig. 3 is the circuit diagram of another embodiment of the utility model

Embodiment one: the structure of this routine described safety cap as shown in Figure 1, it is to be fixed with six light-emitting components 1, power supply 2 and a flasher circuit on the cap base of former small yellow cap, wherein light-emitting component 1 is a light emitting diode, flasher circuit adopts the discrete component astable oscillator, as shown in Figure 2, it is made up of two triode D1, D2 and two capacitor C1, C2 and two resistance R 1, R2, and this circuit is divided into two groups with six light emitting diodes, and makes their alternately flickers.

Only need deenergization when wear daytime, promptly become common small yellow cap, when night or poor visibility, then power turn-on makes light emitting diode send the glory that flashes under the driving of circuit, can play warning function.

Embodiment two: the structure of this routine described safety cap as shown in Figure 1, it is to be fixed with six light-emitting components 1, power supply 2 and a flasher circuit on the cap base of former small yellow cap, this flasher circuit is made of 4000 serial CMOS integrated circuits, as shown in Figure 3.

Claims (4)

1, a kind of safety cap is characterized in that: be fixed with several light-emitting components (1) and power supply (2) on the cap, be connected by a flasher circuit between light-emitting component (1) and the power supply (2).

2, safety cap according to claim 1 is characterized in that: described flasher circuit is mainly connected by 4000 serial COMS integrated circuits.

3, according to the described safety cap of claim 1, it is characterized in that: described flasher circuit is the discrete component astable oscillator.

4, according to claim 1,2 or 3 described safety caps, it is characterized in that: light-emitting component (1) is the colorful light-emitting diode.
