Description

Technical Field

[0001] The present invention relates to a backpack with a manually-triggered protective airbag umbrella function, which is used in situations such as traffic accidents, falling into water, etc., and belongs to the field of personal safety protection. In particular, it is a backpack that can manually trigger a built-in hidden protective airbag umbrella in an emergency to provide semi-wrapped umbrella-shaped protection for vital parts. Background Art

[0002] With the acceleration of urbanization, traffic safety issues around campuses, students falling into water and drowning, and urban waterlogging incidents have occurred frequently, posing a serious threat to the life safety of primary and secondary school students. In response to this, the General Office of the State Council issued the "Implementation Opinions on Strengthening the Construction of Safety Risk Prevention and Control Systems in Primary and Secondary Schools and Kindergartens", and the Ministry of Education also emphasized the importance of building a solid campus safety line. These opinions have received positive responses from various government departments and broad support from all sectors of society, but there is still a lack of sufficient innovation and application of protective measures for individual students, which makes individual students have obvious deficiencies in active protection.

[0003] Patent No. CN218008629U discloses a functional backpack that prevents drowning. The backpack has a safety airbag device that uses gas generated by the reaction of calcium carbonate and water as the airbag inflation gas. However, the reaction rate is low, making it difficult to provide timely and effective protection.

[0004] Patent number CN220360198U discloses a backpack based on safety protection. Its airbag uses an electrically driven pressure sensor to trigger nitrogen to quickly inflate, but the electric drive device is easily damaged and it is difficult to maintain the effectiveness of protection for a long time, and its passive protection may be triggered by mistake.

[0005] The present invention provides a school bag with a manually-fired protective airbag umbrella function to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0008] Further, the airbag umbrella includes a head and neck protection airbag umbrella, two chest and shoulder protection airbag umbrellas and two waist protection airbag umbrellas, the head and neck protection airbag umbrella is built into the head and neck airbag umbrella component, the two chest and shoulder protection airbag umbrellas are built into the chest and shoulder airbag umbrella components of the left and right straps, and the two waist protection airbag umbrellas are respectively built into the two waist airbag umbrella components;

[0009] Furthermore, when the schoolbag, the head and neck protection airbag umbrella, the two chest and shoulder protection airbag umbrellas and the two waist protection airbag umbrellas work together, the airbag umbrellas provide half-wrapped protection for the vital parts of the upper body of the student, forming an umbrella-shaped protection structure, and the inflated and unfolded volumes of the two waist protection airbag umbrellas are smaller than the inflated and unfolded volumes of the head and neck protection airbag umbrella and the two chest and shoulder protection airbag umbrellas;

[0010] Furthermore, a reflective strip is sewn on the top of the head and neck protection airbag umbrella and the front of the two chest and shoulder protection airbag umbrellas respectively, and the reflective strip is a long-direction frame-shaped structure;

[0011] Furthermore, the hidden protective airbag umbrella component comprises a wear-resistant surface layer, a hidden buckle and an airbag umbrella, and the wear-resistant surface layer is in a pocket shape to store the airbag umbrella, and the airbag umbrella is connected to the carbon dioxide compressed gas device;

[0012] Furthermore, the airbag umbrella is in a negative pressure vacuum form, and when it is actively triggered to work, it is inflated and expanded by the connected carbon dioxide compressed gas device and its own negative pressure at the same time;

[0013] Further, the manual firing device includes a pull ring, a traction rope, an air valve plug, an air pipe and a carbon dioxide compressed gas device, and the pull ring is placed on the inner side of the left shoulder strap and is made of a wear-resistant surface layer to form a double-door anti-mistouch protective cover, and the pull ring is connected to the traction rope, and the traction rope is connected to the air valve plug, and the air valve plug is connected to the carbon dioxide compressed gas device, and the carbon dioxide compressed gas device is respectively connected to the head and neck protection airbag umbrella, two chest and shoulder protection airbag umbrellas and two waist protection airbag umbrellas through the air pipe;

[0014] Furthermore, the left and right shoulder straps each have a shoulder strap, one end of the shoulder strap is sewn on the chest and shoulder protective airbag umbrella, and a limiting device is provided at the place where the shoulder strap enters the left and right shoulder straps respectively.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) The present invention provides protection for students' vital parts by providing a protective airbag umbrella system, for example, the head and neck protective airbag umbrella provides protection for the student's head and neck, the chest and shoulder protective airbag umbrella provides protection for the student's chest and shoulders, and the waist protective airbag umbrella provides protection for the student's waist;

[0017] (2) The present invention improves the inflation and deployment mechanism of the airbag umbrella, thereby changing the deficiencies of the inflation method of the existing inflation system; the airbag umbrella of the present invention is in a negative pressure vacuum state under normal conditions, and the air valve plug is opened by actively triggering the manual firing device, so that the airbag is quickly inflated and deployed under the dual effects of negative pressure air intake and carbon dioxide inflation, which helps to provide efficient protection for students;

[0018] (3) The present invention connects the chest and shoulder protection airbag umbrella with the shoulder strap, so that the shoulder strap can be tightened when the airbag umbrella is deployed, so that the schoolbag can tightly wrap the student, avoiding the fall of the protective equipment in an emergency. The shoulder strap is provided with a limit device at the place where it enters the left shoulder strap and the right shoulder strap, so as to avoid the airbag umbrella from being damaged in daily use, thereby increasing the reliability of protection.

[0019] (4) The inflated and deployed volume of the head and neck protection airbag umbrella and the chest and shoulder protection airbag umbrella of the present invention is larger than the inflated and deployed volume of the waist protection airbag umbrella, so that when students trigger the airbag umbrella in the event of falling into the water, their heads can be above the water surface with their faces facing upwards, thereby increasing functionality and usability;

[0020] (5) The present invention provides students with active protection capabilities in emergency situations by providing a manual firing device. BRIEF DESCRIPTION OF THE DRAWINGS
