Abstract

The utility model provides a caution schoolbag which is formed by a bag body and straps, wherein a pressure sensor, a direct-current power supply and LED (Light Emitting Diode) lamps are arranged on the straps and the bag body to form a current loop; fluorescent strips are arranged on the left and right faces as well as the front face of the bag body; and the LED lamps are arranged at the upper and lower sides of the fluorescent strips. According to the caution schoolbag disclosed by the utility model, the fluorescent strips and the LED lamps are arranged on the left and right faces as well as the front face of the bag body, so that the LED lamps enter a working state when a student wears the schoolbag under the effect of the pressure sensor, thereby remind passing drivers of paying attention to the students wearing the schoolbags and reducing the accident possibility.

Description

A kind of caution school bag

Technical field

The utility model relates to a kind of school bag, and especially a kind of caution school bag belongs to the daily living article technical field.

Background technology

School bag is as the indispensable instrument of students reading now, and general only for the purposes of dress band textbook, function ratio is more single.And some improvement to school bag also only are the spaces that increases some storings on the market, are not having too many improvement aspect student's safeguard protection.And the student is as disadvantaged group, when wearing road or walk some Dangerous Areas, especially under misty rain weather, low visibility, be easy to be ignored by passing driver, particularly at present private car is more and more, do not emerge in an endless stream because the driver sees wound student's event of the place ahead road conditions, and this type of event has the trend of increase.

The utility model content

The technical problems to be solved in the utility model is: a kind of school bag with alarm function is provided, solves existing safety problem.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of caution school bag, formed by inclusion and braces, and be provided with pressure inductor, dc source and LED lamp at braces and inclusion, the three forms current loop; The left and right two sides of described inclusion and front are provided with phosphor strip, and LED lamp apportion phosphor strip is both sides up and down.

Described a kind of caution school bag, the pressure inductor on its inclusion has 4, is separately positioned on four diagonal angles of inclusion, apart from inclusion edge 15cm-20cm.

Described a kind of caution school bag, the pressure inductor on the braces has 2, is separately positioned on the shoulder position of 2 braces.Adopt this kind design, when student's back school bag, on the braces and the pressure inductor on the inclusion connect electric power loop, the LED lamp on school bag will be shinny automatically, plays the purpose of reminding passing driver.

Described a kind of caution school bag, the left and right two sides of inclusion and positive phosphor strip have 2, lay respectively at the inclusion center and are offset on the seat of 20cm-30cm to both sides.Fluorescent belt and LED lamp arrange mutually, can prevent when power supply is used up, and fluorescent belt can rely on the light of automobile can reflect light, still can play caution driver's effect.

Described a kind of caution school bag, also be connected with oscillator and delay circuit between pressure inductor, dc source and the LED lamp, the current loop of delay circuit control generator, pressure inductor, dc source, LED lamp, oscillator and delay circuit are formed a current loop.Adopt this kind design, can guarantee after the student unloads school bag, delay circuit still can continue to connect a period of time, and by the effect of oscillator, the LED lamp still can be luminous automatically, plays the effect of safety instruction.

The utility model arranges phosphor strip and LED lamp in the left and right and front of school bag, under the effect of pressure inductor, form the closed-loop path with dc source, LED lamp, can play the effect of reminding passing driver, and production cost is low, result of use is good, can strengthen visual effect better, remind passing driver to note the student who endorses and wrap, the probability that the reduction accident takes place.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, a kind of caution school bag is made up of inclusion 1 and braces 2, is provided with pressure inductor 12, dc source 10 and LED lamp 9 at inclusion 1 and braces 2, and the three forms current loop; Be provided with phosphor strip 4 on the left and right two sides of inclusion and front, about in the of 4 both sides for LED lamp 9 apportion phosphor strips.

Pressure inductor 12 on the described inclusion 1 has 4, is separately positioned on four diagonal angles of inclusion, apart from inclusion edge 15cm-20cm.

Pressure inductor 12 on the described braces 2 has 2, is separately positioned on the shoulder position of 2 braces.At shoulder and inclusion pressure inductor is set, can plays the detection effect better, guarantee that the very first time of student's back school bag just can sense, and instrument is brought into operation.

The left and right two sides of described inclusion and positive phosphor strip 4 have 2, lay respectively at the inclusion center and are offset on the seat of 20cm-30cm to both sides.

Also be connected with oscillator 11 and delay circuit 6 between described pressure inductor 12, dc source 10 and the LED lamp 9, the current loop of delay circuit control generator, pressure inductor 12, dc source 10, LED lamp 9, oscillator 11 and delay circuit 6 are formed a current loop.
