Three indicating lamps which are provided with red or yellow transparent organic glass covers are respectively arranged on the front surface of the satchel, the left side surface and the right side surface of the satchel. Other components are sealed in a rectangular casing, and the other components are fixed on any inner surface of the six surfaces of the satchel or on the inner surface of the cover of the satchel by rivets or screws and screw caps; a switch adopts a conversion type or a button type. When children walk on a vehicle path or pass across the vehicle path, bicycles and automotive vehicles on the left, the right and the rear of the children can be early reminded by the flashing and the sound can to notice the children safety.

Description

Sound and light safety reminding satchel

The utility model relates to a kind of student's school bag, specifically belongs to a kind of school bag with the acousto-optic hint device.

In the city, the safety that the student goes across the road relates to the major issue of huge numbers of families' happiness.Safety that children crossing though useful in recent years small yellow cap is pointed out the motor vehicles driver, but, because the degree that small yellow cap arouses vigilance is very limited, and under It is gloomy or dim light of night situation, also there is the not good enough problem of effect, therefore, children's casualty accident of causing of bicycle and motor vehicles still occurs repeatedly.

The purpose of this utility model provides a kind ofly points out intensity school bag big, band sound, light suggestion device.

The utility model is made up of school bag harmony, light suggestion device two large divisions.School bag can adopt the common school bag of the hard backboard of biobelt, also can adopt its front to be connected with slide fastener with top and left and right sides face, and the bottom is lined with the box school bag of hardboard.The acousto-optic hint device is made up of parts such as housing, integrated circuit, light cue circuit, sound cue circuit, dc sources.The light cue circuit comprises switch, three triodes and three indicator lamps; The sound cue circuit comprises resistance, triode, switch and loudspeaker.One termination power negative pole of light cue circuit switch, the other end links to each other with No. 10 pin of integrated circuit, the base stage of three triodes links to each other with 3,4, No. 5 pin of integrated circuit respectively, 1. colelctor electrode is connected on respectively on number connecting line, emitter stage links to each other with indicator lamp respectively, 2. the other end of indicator lamp is connected on respectively on number connecting line, and 2. number connecting line links to each other with power cathode.1. an end of number connecting line and loudspeaker one end join, and the other end links to each other with No. 6 pin of integrated circuit; The base stage of triode of sound cue circuit links to each other with No. 2 pin of integrated circuit, and 2. emitter stage is connected on number connecting line, and switch is connected between the colelctor electrode and loudspeaker of triode, and resistance is connected between 8, No. 9 pin of integrated circuit.No. 6, No. 1 pin of integrated circuit connects the power supply positive and negative electrode respectively.Three indicator lamps can be installed in respectively on the parcel of the front of school bag and left and right sides face; Other components and parts of acousto-optic hint device are encapsulated in a rectangular metal (or plastics) housing, with rivet or screw, fixed by nut at the arbitrary inner surface of six faces of school bag or the inner surface of clad.Switch is arranged on the front plate of housing, and power supply is located in the groove of housing bottom panel below.One tegillum is arranged on the groove, at groove lower edge place, two rectangle apertures are arranged, there are two male tabs unidimensional with the hole at the corresponding position of rectangle aperture with groove on tegillum.There is the little handle of the dark formula of a T type top of tegillum, and tegillum and housing fasten with taking by mode.Above the backplate of housing, reach the left and right sides and leave small sircle hole respectively, the connecting line of indicator lamp is drawn from the hole, use the cloth overseam on the linear slit of school bag.Switch can adopt change-over switch, also can adopt press button; Have redness or yellow transparent plexiglass tent on the indicator lamp.

Principle of the present utility model is: when the student goes across the road, can push away earlier (or by) light prompting switch, at this moment, the different pulse signal electric current of three tunnel phase places of integrated circuit output makes three evenly spaced conductings of triode of light cue circuit or ends, and three indicator lamps are luminous flickeringly thereupon; And then open prompting switch, and the sound cue circuit is connected, and the pulse signal electric current of (utilizing resistance R to change the frequency of integrated circuit oscillator), integrated circuit output amplifies through triode, promotes the loudspeaker sounding.

The utility model modern design, point out effective, no matter daytime or night; Children walk on the track or when crossing, and with the driver of the cyclist at rear and motor vehicles children crossing safety, effectively prevent the children traffic safety accident about flash of light and sound all can be reminded early.

The utility model can adopt box open method, can regard case again as bag, for children provide convenience with the exhibition of keeping flat of books dress, and can prevent that books wrinkle mill is mashed.

The utility model is cheap; can not only protect children's safety; remove father and mother's worry; and appearance and modeling and light, sound design meet children 's interests again; use, easy to maintenance; its components and parts are all selected available and cheap national standard part for use everywhere, and common people's dismounting repairing also is convenient in the design of modeling structure.Design of the present utility model also can be used for various traveling bag, bag.

Fig. 1 is a structural representation of the present utility model.10 is school bag among the figure, H ₁, H ₂, H ₃Be respectively indicator lamp, 11 is the housing of sound, light suggestion device, K ₁Be the switch of light cue circuit, K ₂Switch for the sound cue circuit.
