Description

Safe school bag

Technical field

This utility model relates to a kind of school bag, particularly relates to a kind of safe school bag.

Background technology

Student is pitch-dark when classes are over, can can't see and cycle or the student of walking, be susceptible to traffic during motor vehicle running Accident, meanwhile, student carries school bag when walk on the way, may meet with bad person and pull school bag, it is desirable to provide one is walked Night can warn on road, and time of crisis can also frighten bad person the school bag warned.

Utility model content

The technical problems to be solved in the utility model is to provide one can send alarm, simultaneously can night road enterprising The safe school bag that row is warned.

The technical scheme realizing this utility model purpose is: safe school bag, and including school bag body, walking along the street alarm unit is urgent Alarm unit and supplying cell, walking along the street alarm unit, emergency alarm unit and supplying cell are all bonded on school bag body, power Battery is respectively walking along the street alarm unit and emergency alarm unit provides electric energy, and walking along the street alarm unit includes the luminescence of several parallel connections Diode and the first switch, one end of the first switch is connected with the positive pole of supplying cell, and the other end of the first switch is with some The positive pole of the light emitting diode of individual parallel connection is connected, the negative pole phase of the negative pole of the light emitting diode of several parallel connections and supplying cell Connecting, emergency alarm unit includes that second switch, display lamp and buzzer, second switch, display lamp and buzzer are connected in series Between the positive pole and the negative pole of supplying cell of supplying cell.

As prioritization scheme of the present utility model, the supply voltage of supplying cell is 3V.

As prioritization scheme of the present utility model, safe school bag includes even number light emitting diode, even number light-emitting diodes The left and right sides being arranged on school bag body front that pipe is symmetrical.

This utility model has a positive effect: this utility model simple in construction, play warning by light emitting diode Effect, is reported to the police by buzzer, observes and cycles or the student of walking, it is to avoid send out when being possible not only to so that motor vehicle running Raw vehicle accident, can also frighten bad person simultaneously in times of crisis, is operated respectively by the first switch and second switch, behaviour Make simple and convenient, effectively ensured the safety of student.

Accompanying drawing explanation

In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine attached Figure, is described in further detail this utility model:

Fig. 1 is circuit connection diagram of the present utility model.

Wherein: 1, walking along the street alarm unit, 2, emergency alarm unit, 11, light emitting diode, the 12, first switch, 21, second Switch, 22, display lamp, 23, buzzer, 3, supplying cell.

Detailed description of the invention

As it is shown in figure 1, the utility model discloses safe school bag, including school bag body, walking along the street alarm unit 1, promptly report Warning unit 2 and supplying cell 3, walking along the street alarm unit 1, emergency alarm unit 2 and supplying cell 3 are all bonded on school bag body, Supplying cell 3 respectively walking along the street alarm unit 1 and emergency alarm unit 2 provide electric energy, walking along the street alarm unit 1 to include that several are also The light emitting diode 11 of connection and the first switch 12, one end of the first switch 12 is connected with the positive pole of supplying cell 3, the first switch The other end of 12 is connected with the positive pole of the light emitting diode 11 of several parallel connections, bearing of the light emitting diode 11 of several parallel connections Pole is connected with the negative pole of supplying cell 3, and emergency alarm unit 2 includes second switch 21, display lamp 22 and buzzer 23, and second Switch 21, display lamp 22 and buzzer 23 are connected in series between the positive pole of supplying cell 3 and the negative pole of supplying cell 3.

The supply voltage of supplying cell 3 is 3V, saves the most general No.5 cell by two and is powered, replacing side Just, simply.

Safe school bag includes even number light emitting diode 11, even number light emitting diode 11 symmetry be arranged on school bag body The left and right sides in front, wherein, two row light emitting diodes 11 so that motor vehicles under steam observe cycle and walk Student, thus take Forewarning Measures in advance, it is to avoid the generation of vehicle accident.

Light emitting diode 11, first switchs 12, buzzer 23, display lamp 22, second switch 21 and supplying cell 3 all to be passed through Wire is weldingly connected, and is arranged with heat-shrink tube at pad, and wire is arranged with plastic bushing.By sheathed heat-shrink tube and plastics The circuit of safe school bag is effectively protected by sleeve pipe, it is to avoid rupture of line.

During use, time rather dark, carry safe school bag, open the first switch 12, thus light light emitting diode 11 and enter Row warning, in case of emergency, opens second switch 21, and buzzer 23 will send and pipe, and display lamp 22 is easy to week simultaneously Enclose personnel positioning.

It addition, in order to save electric energy, it is possible to use rechargeable battery, as supplying cell 3, arranges carbon film on school bag body It is rechargeable battery charging that fever tablet can directly utilize solar energy, has effectively saved the energy.Can also add on school bag body Dress Shock inductor, Shock inductor is connected with buzzer 23, opens second without the time after installing Shock inductor Switch 21, during pullling safe school bag, Shock inductor also can be triggered, and buzzer 23 pipes warning, adds peace The safety coefficient of pandect bag.

Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect Step describes in detail, be it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this Utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, all should wrap Within being contained in protection domain of the present utility model.
