Description

Technical Field

[0001] This utility model relates to the field of schoolbag technology, specifically a schoolbag with shock absorption and cushioning. Background Technology

[0002] Schoolbags are essential items in students' daily lives, carrying various books, stationery, and other learning materials. However, traditional schoolbags have many shortcomings in design and function, especially in shock absorption and cushioning, failing to meet the needs of students' daily use and causing them some inconvenience.

[0003] When students carry their backpacks while walking or running, the backpacks sway and vibrate with their body movements. Traditional backpacks often lack effective shock-absorbing structures at the bottom. When the backpack collides with the ground or other objects, the impact is directly transmitted to the items inside, easily damaging books, stationery, and other valuables. Especially for expensive electronic learning devices such as tablets and electronic dictionaries, even slight vibrations can cause irreversible damage, affecting their normal use and lifespan. Furthermore, students bear significant pressure on their shoulders when carrying traditional backpacks. The shoulder straps of traditional backpacks are often poorly designed, lacking effective cushioning and pressure distribution mechanisms. After prolonged use, students are prone to shoulder pain, fatigue, and other discomfort. In severe cases, this may even affect spinal development, posing a potential threat to their health. Especially when students go up and down stairs or engage in strenuous exercise, the swaying of the backpack further increases the burden on the shoulders, exacerbating discomfort. At the same time, traditional backpacks are also relatively unstable when carried. Because the backpack doesn't fit snugly against the back, it's prone to slipping or wobbling while walking or exercising. Students need to constantly adjust their posture to maintain balance, which not only increases their physical exertion but may also distract them and affect the safety of their learning and activities. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing and cushioning backpack to address the issue mentioned in the background art where backpacks sway and vibrate with body movement during walking or running. Traditional backpacks typically lack effective shock-absorbing and cushioning structures at the bottom. When the backpack collides with the ground or other objects, the impact force is directly transmitted to the items inside, easily damaging books, stationery, etc. Especially for expensive electronic learning devices such as tablets and electronic dictionaries, even slight vibrations can cause irreversible damage, affecting their normal use and lifespan. Furthermore, students bear significant pressure on their shoulders when carrying traditional backpacks. The shoulder strap design of traditional backpacks is often inadequate, lacking effective cushioning and pressure distribution mechanisms. After prolonged carrying, shoulder pain, fatigue, and other discomfort symptoms are common, and in severe cases, it may even affect the student's spinal development, posing a potential threat to their health. Especially when students go up and down stairs or engage in strenuous exercise, the swaying of the backpack further increases the burden on the shoulders, exacerbating discomfort. At the same time, traditional backpacks also have poor stability when carried. Because the backpack doesn't fit snugly against the back, it's prone to slipping or wobbling while walking or exercising. Students need to constantly adjust their posture to maintain balance, which not only increases their physical exertion but may also distract them and affect the safety of their learning and activities.

Back insulating strips 10 are horizontally and evenly fixed on one side of the main backpack body 1. The insulating strips 9 are made of soft rubber and are symmetrically fixed in pairs at the side openings of the movable slots 8. There are multiple back insulating strips 10, which are equidistantly and parallelly arranged at the center line of the side edge of the main backpack body 1. The inner top of the side fixing slots 6 and... The bottom end is symmetrically provided with end limiting holes 11, and a connecting spring 12 is fixedly engaged with the inner side of the end limiting hole 11. The inner side of the side fixing groove 6 is symmetrically provided with limiting inner grooves 13, and the inner side of the side fixing groove 6 is vertically engaged with a movable locking plate 14. The two sides of the movable locking plate 14 are symmetrically fixed with limiting side strips 15.

One end of the connecting spring 12 extends and is fixedly connected to the inner side of the stabilizing end hole 16. The side of the limiting side strip 15 is vertically engaged with the inner side of the limiting inner groove 13. The stabilizing end holes 16 are symmetrically provided at the center positions of the two ends of the movable locking plate 14.

[0020] The connection spring 12 not only provides a certain elasticity to keep the shoulder strap in the right position, but also further cushions the pressure on the shoulder during the student's walking or exercise, distributes the burden on the shoulder, effectively reduces shoulder pain and fatigue, and protects the student's spinal health.

[0021] Working principle: Students place books, stationery, and other school supplies into the main backpack body 1, then zip up one side of the backpack cover 2. The other sides of the backpack cover 2 are then fixedly connected to the top opening of the main backpack body 1 via zippers, thus sealing the items inside the backpack. When students carry the backpack while walking or exercising, multiple support plates 3 evenly distributed on the bottom surface of the main backpack body 1 provide support. The horizontally fixed cushioning strips 4 on the bottom surface of the support plates 3 are made of soft rubber material, possessing good elasticity and cushioning performance. When the backpack collides with the ground or other objects, the cushioning strips 4 are the first to receive the impact force and deform, absorbing and dispersing part of the impact force, reducing the vibration transmitted to the main backpack body 1, thereby protecting the items inside the backpack from damage. Regarding shoulder strap adjustment, a fixed inner plate 7 is vertically fixed within a symmetrically vertically opened side fixing groove 6 on one side of the main backpack body 1. A symmetrically fixed isolation strip 9 is engaged within a vertically opened movable slot 8 on the side of the fixed inner plate 7. The movable plate 14 is vertically engaged within the side fixing groove 6, and its two side limiting strips 15 are correspondingly engaged within the symmetrically opened limiting inner grooves 13 on the side of the side fixing groove 6 to prevent the movable plate 14 from dislodging. The stabilizing end holes 16 at both ends of the movable plate 14 are connected to the end limiting holes 11 at the top and bottom of the side fixing groove 6 via connecting springs 12. The top of the shoulder strap 5 is fixedly connected to the top of one side of the movable plate 14. Students can pull the shoulder strap 5 up or down according to their height and comfort needs, causing the movable plate 14 to move up and down within the movable groove 8. The connecting spring 12 provides a certain elasticity, keeping the shoulder strap 5 in a suitable position and allowing for flexible adjustment of the shoulder strap length. Multiple back support strips 10, made of soft material, are horizontally and evenly fixed on one side of the main backpack body 1. When students carry the backpack, they can increase air circulation between the backpack and their back, reduce stuffiness, improve the fit between the backpack and their back, enhance carrying stability, and reduce backpack swaying.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
