Abstract

The utility model relates to a safety schoolbag, particularly a schoolbag which is provided with a light-emitting device and used for students. The utility model comprises a schoolbag body 1 and shoulder straps 2. The utility model is characterized in that an electronic light-emitting device is arranged on the schoolbag body, and the light-emitting component 3 of the electronic light-emitting device is arranged on the outer side surface of the schoolbag body. When the switch of the electronic light-emitting device is closed, an electronic light-emitting signal can be displayed by the safety schoolbag which is carried on the back of the student to warn to-and-fro people who drive vehicles to notice the walking safety of the student. The utility model has the advantages of novel structure, convenient use and good safety. The utility model is an applicable and novel appliance for the students.

Description

Safety bag

The utility model relates to a kind of safe school bag, particularly a kind of school bag that supplies the student to use that has electron emitting structure.

Existing student's school bag only has the function of dress book, sets out on a journey when the student carries school bag, when particularly go across the road night, can't send alarm signal to coming vehicle, to guarantee walking along the street safety.

The purpose of this utility model is that a kind of school bag will be provided, and it not only has dress book function, and can show the electron luminescence signal, thereby the driving person of warning dealing notes student's walking along the street safety.

The utility model is to constitute like this, and it comprises school bag and braces, it is characterized in that the school bag body is provided with electron emitting structure, and the light-emitting component of electron emitting structure places the lateral surface of school bag body.

Below in conjunction with drawings and Examples utility model is specifically described.

Fig. 1 is embodiment one organigram (5 are transparent protective shield among the figure).

Fig. 2 is the working circuit diagram of embodiment one.

Fig. 3 is embodiment two organigrams (5 are transparent protective shield among the figure).

Fig. 4 is the working circuit diagram of embodiment two.

With reference to Fig. 1, Fig. 2, embodiment one of the present utility model comprises school bag body 1, braces 2 and be located at electron emitting structure on the school bag body.

The operating circuit of electron emitting structure has battery E ₁, K switch ₁, vibration trigger, decimal system cycle counter and ten light emitting diode D that are connected to decimal system cycle counter output.The vibration trigger is by two phase inverter I of integrated package CD4069 ₁, I ₂, resistance R and capacitor C are formed; Decimal system cycle counter is made of integrated package CD4017; Phase inverter I ₁Input and the negative pole of capacitor C and an end of resistance R join phase inverter I ₁Output and phase inverter I ₂Input and the other end of resistance R join phase inverter I ₂Output join with the positive pole of capacitor C and the input CL of integrated package CD4017.Ten light emitting diode D(are 3 among Fig. 1) be laid in the trailing flank of school bag body.

The course of work of embodiment one is: K closes a switch ₁, operating circuit is connected power supply E ₁, by phase inverter I ₁, I ₂And the input CL of integrated package CD4017 delivered to a series of pulse signals that produced by the vibration trigger of peripheral circuit composition, when the vibration trigger is exported just along trigger impulse, decimal system cycle counter counting, output is exported high level signal successively and is driven ten light emitting diodes being located on the school bag body trailing flank.So the back of the body is noted student's walking along the street safety at student's school bag on one's body signal that just constantly flashes with the driving person of warning dealing.

Fig. 3 is the organigram of embodiment two, and Fig. 4 is the working circuit diagram of embodiment two.Embodiment two comprises the school bag body, braces and be located at electron emitting structure on the school bag body, and the characteristics of its structure are that the operating circuit of electron emitting structure is by battery E ₂, K switch ₂Form with several miniature bulbs that are in parallel 4, miniature bulb 4 is laid in the trailing flank of school bag body.As the K that closes a switch ₂, miniature bulb can be shinny.

The utlity model has following remarkable advantage: 1, be conducive to the safety of student walking along the street. This is because school bag body trailing flank is provided with electron emitting structure, can warn dealing driving person to note endorsing and wrap student's walking along the street safety. 2, the appearance novelty has aesthetic feeling. Because electronic light-emitting component can produce luminous or flicker effect, therefore has aesthetic feeling. 3, easy to use, as long as close a switch when the student sets out on a journey, the electron emitting structure of this school bag is namely started working.

The utility model structure is novel, easy to use, and security is good, and its popularizing application prospect is considerable.
