Abstract
The utility model relates to the field of school supplies, in particular to a safety warning schoolbag which comprises a schoolbag body, wherein a safety warning device is inlaid on the front surface of the schoolbag body; the safety warning device consists of a shell, an LED (light-emitting diode) warning light panel and a switch; the LED warning light panel is provided with a plurality of LEDs which are connected in parallel; a circuit module electrically connected with the LEDs is arranged in the shell; and the LEDs adopt micro-electronic stroboscope lamps with low energy consumption and wide wavelength. Therefore, the visual range is large day or night, the visible range is long, the close range light is soft and does not harm the eyes, and the lamps can be used for a week continuously after one-time charging. The safety warning device is inlaid on the front surface of the schoolbag body and the flare light emitted by the warning device has active warning function for vehicles driving from the sides and back within 30-50 meters and can effectively draw the attention of the driver, so that the traffic accident probability is reduced, and the safety warning schoolbag has good protection function for the walking children.
Description
Technical field
The utility model relates to the students' supplies field, particularly be a kind of warning safe school bag.
Background technology
Along with sharply the increasing of China's vehicle (12% motor vehicle growth rate is arranged every year), the traffic accident injury accident sharply increases.Show according to investigations; because of children's self-precaution consciousness and self-protection ability a little less than; China has at least 77 children below 15 years old injured every day because of traffic accident, have at least 19 dead because of traffic accident, wherein in per ten traffic injuries 4.4 victims just being arranged is walking children.It is injured or lose one's life because of traffic accident when China has more than 16100 children in walking an every year, be to have every day 9 walking children dead because of traffic accident, 31 walking children are wounded or disabled because of traffic accident, the shade that traffic accident has brought irremediable injury and can not eliminate for family has one by one also caused the huge social burden.Therefore, traffic safety is the active demand of each family.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of warning safe school bag is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of warning safe school bag, comprise the school bag body, the positive facade of described school bag body is inlaid with safety warning device, described safety warning device is made of shell, LED caution tabula rasa and switch, described LED caution tabula rasa is provided with several light emitting diodes in parallel, and enclosure is provided with the circuit module that is electrically connected with light emitting diode.
Described light emitting diode adopts the microelectronics stroboscopic lamp.
Described circuit module is made up of charging circuit and the no stable state multi resonant flashing circuit that shakes.
The described no stable state multi resonant positive-feedback circuit that flashing circuit comprises that the two-stage phase inverter is formed that shakes.
By adopting above-mentioned technical scheme; the beneficial effects of the utility model are: inlay safety warning device by the positive facade at the school bag body; the passage of scintillation light of utilizing attention device to send; the vehicle that travels with the back side is from the side carried out active warn in that 30-50 rice distance is interior; can effectively cause driver's attention; thereby reduce traffic accident generation probability; the walking children there is good protective effect; the wide wavelength microelectronics of the low energy consumption of being adopted stroboscopic lamp; no matter day and night, visual range was far away; visible range is big; closely the soft eye of not hindering of light charges and once can use 1 time-of-week continuously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit module circuit theory diagrams of the present utility model;
Fig. 3 is a circuit of LED schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of warning safe school bag of the present utility model comprises school bag body 1, the positive facade of described school bag body 1 is inlaid with safety warning device 2, described safety warning device 2 is by shell 21, LED caution tabula rasa 22 and switch 23 constitute, described LED caution tabula rasa 22 is provided with several light emitting diodes in parallel 24, shell 21 inside are provided with the circuit module that is electrically connected with light emitting diode 24, described light emitting diode 24 adopts the microelectronics stroboscopic lamp, no matter day and night, visual range was far away for it, visible range is big, closely the soft eye of not hindering of light charges and once can use 1 time-of-week continuously.
As shown in Figure 2; described circuit module is made up of charging circuit and the no stable state multi resonant flashing circuit that shakes; 5V voltage connects triode Q1 emitter stage from power supply DC input through resistance R 1 and exports to battery charge; current-limiting resistance R2, sample resistance R1; Zener diode D1 plays overshoot protection; Zener diode D1 is stabilized in 3.3V to the base voltage of triode Q1, triode Q1 turn-on battery charging when cell voltage is lower than 2.6V.Charging current is about 350mA and raises along with cell voltage and reduce, and when cell voltage was higher than 2.6V, triode Q1 was by stopping charging.The emitter stage of another routing resistance R8 connection triode Q2 is parallel resistance R7 and LED composition charging indication again, resistance R 7 is the current-limiting resistance of LED, electric current by LED is about 30mA, when cell voltage was higher than 2.6V, triode Q1 ended, and its collector voltage is that 1.5V, triode Q2 base voltage also are 1.5V, resistance R 1 there is not electric current, triode Q2 emitter voltage also is 0, and triode Q2 ends, and charging indicator light goes out.The no stable state multi resonant positive-feedback circuit that flashing circuit comprises that the two-stage phase inverter is formed that shakes, or triode Q3 conducting, triode Q4 ends; Or triode Q3 ends triode Q4 conducting.
As shown in Figure 3, compose in parallel caution tabula rasa circuit by 12 LED lamps, its voltage is provided by the no stable state multi resonant flashing circuit that shakes, the LED lantern festival is sent yellow light, resistance R 1-R12 is the current-limiting resistance of every LED lamp, is about 35mA by the LED electric current.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
