The embodiment provides a safety backpack with an inflatable airbag 6, as shown in fig. 1-4, comprising a backpack body 1, a gas inflator 5, an airbag 6 and a sensing circuit board 7;

the backpack comprises a backpack body 1 and is characterized in that an accommodating cavity 4 is formed in the top of the backpack body 1, a cavity cover 2 is arranged at an opening 3 of the accommodating cavity 4, a gas inflation device 5, an airbag 6 and a sensing circuit board 7 are located in the accommodating cavity 4, and an air tap of the airbag 6 is fixed on the gas inflation device 5;

the sensing circuit board 7 is electrically connected with the gas inflator 5, and when the gas inflator 5 inflates the airbag 6, the airbag 6 in the contracted state rushes open the cavity cover 2 under the pressure of gas and releases and deploys towards the head of a user carrying the backpack.

The sensing circuit board 7 of the embodiment is provided with a sensor and a microprocessor, and the sensor and the gas inflator 5 are respectively and electrically connected with the microprocessor. The sensor adopts a gyroscope sensor or an inclination angle sensor or a speed sensor, when a user carrying the backpack has a collision accident or falls down carelessly, the sensor is used for adopting inclination angle information of the user and sending the inclination angle information to the microprocessor, the microprocessor controls the gas inflating device 5 to inflate the gas bag 6 according to the inclination angle information, the gas bag 6 filled with gas gradually is flushed out from the opening 3 of the accommodating cavity 4 and unfolded, the gas bag 6 is in a helmet shape when being released and unfolded, and the head of the user is sunk into the gas bag 6 and wound around the head of the user around the gas bag 6, so that the head of the user is protected.

Specifically, the gas inflator 5 of the present embodiment includes a partition 51, a connection passage 52, a puncture needle 53, a needle drive mechanism 54, and a gas tank 55;

the partition plate 51 divides the accommodating chamber 4 into an upper accommodating chamber 41 and a lower accommodating chamber 42, the airbag 6 in a contracted state is positioned in the upper accommodating chamber 41, and the air storage tank 55, the connecting passage 52 and the sensing circuit board 7 are positioned in the lower accommodating chamber 42;

an opening at one end of the connecting channel 52 is fixed on the partition plate 51, a through hole 511 is arranged on the partition plate 51 opposite to the opening, and an air tap of the air bag 6 is fixed on the through hole 511 for a circle;

the other end of the connecting passage 52 is fixed to a tank cover of the air tank 55;

the needle driving mechanism 54 and the puncture needle 53 are located in the connecting channel 52, the puncture needle 53 is driven by the driving mechanism to puncture the cover of the gas storage tank 55, and the gas in the gas storage tank 55 flows into the airbag 6 through the connecting channel 52.

The gas container 55 of this embodiment stores compressed carbon dioxide, and the carbon dioxide flows into the air bag 6 through the connecting passage 52. In order to prevent gas leakage during the inflation of the airbag 6, which cannot achieve the purpose of rapid inflation, the present embodiment is provided with a sealing ring at the contact position of the connecting passage 52 and the cover of the gas tank 55, and a sealing ring at the contact position of the connecting passage 52 and the partition 51, thereby preventing gas leakage.

The needle drive mechanism 54 of this embodiment employs a push-pull electromagnet 54 of the prior art; the tail end of the push-pull rod of the push-pull electromagnet 54 is connected with the puncture needle 53, and when the push-pull rod of the push-pull electromagnet 54 is pushed out, the puncture needle 53 moves forwards along with the push-pull rod to puncture the can cover of the gas storage tank 55.

The power supply 8 in this embodiment supplies power to the sensor, the microprocessor and the push-pull electromagnet 54, and the microprocessor is used for controlling the push-pull electromagnet 54 to be electrified or powered off. In the embodiment, the end of the push-pull rod of the push-pull electromagnet 54 faces the tank cover of the gas tank 55, and the end of the puncture needle 53 on the push-pull rod also faces the tank cover of the gas tank 55, so that when the push-pull electromagnet 54 is electrified, the push-pull rod is pushed out, the push-pull rod and the puncture needle 53 move towards the tank cover of the gas tank 55, and the tank cover is punctured, and carbon dioxide gas in the gas tank 55 flows out. When the push-pull electromagnet 54 is de-energized, the push-pull rod is restored to the initial position.

In this embodiment, in order to enable the airbag 6 to be deployed toward the head of the user, the cavity of the accommodating cavity 4 is inclined at a certain angle toward the strap of the safety backpack, so that the airbag 6 can be better oriented toward the head of the user when being flushed out from the opening 3, thereby protecting the head of the user.

In this embodiment, the lid adopts the magic area at the chamber lid 2 that holds 4 openings 3 departments in chamber, the size in magic area 2 is greater than the open-ended size, the one end in magic area 2 is fixed on the knapsack body 1, magic area 2 glues in hold 3 a week in opening in chamber 4. Magic area 2 glues on knapsack body 1, inflates at gasbag 6 and dashes out the time, because impulsive force is stronger, can be very easy dash out magic area 2, from holding dashing out in the chamber 4.

The backpack body 1 of the embodiment is provided with the cup bag 9, and the cup bag 9 is located in the middle or at two sides of the surface of the backpack body 1. The cup bags 9 are used for storing cups, and in order to keep the backpack for storing the cups balanced, one cup bag 9 is arranged in the middle of the surface of the backpack body 1, or two cup bags 9 are arranged on two sides of the surface of the backpack body 1.

In summary, the safety backpack with the inflatable airbag 6 of the present embodiment can protect the head of the user. When a user carrying the backpack has a collision accident or falls down carelessly, the air bag in the backpack is released and unfolded rapidly to wrap the head of the user, so that the head of the user is prevented from being injured, and safety guarantee is provided for the user.
