Description

Technical Field

[0001] The present invention relates to the technical field of schoolbags, and specifically to an external assistance type burden-reducing schoolbag for primary and secondary school students based on the application of artificial intelligence mechanical exoskeletons. Background Art

[0002] As social competition becomes increasingly fierce, parents' expectations for their children are constantly rising, which directly leads to the increasing academic burden on children. The number and weight of books loaded in the schoolbag are increasing day by day, bringing heavy physical pressure to children who are in the critical period of growth and development. Taking junior high school students as an example, the teaching materials and supplementary teaching materials that first-year junior high school students need to carry every day weigh up to 5 kilograms. Coupled with various notebooks, exercise books, correction notebooks and stationery, the total weight increases by another 5 kilograms. In addition, the schoolbag itself weighs 3 kilograms, and a water-filled kettle also weighs 2 kilograms. In this way, the total weight that children need to carry every day is as high as 15 kilograms, which undoubtedly causes a great burden on their bodies;

[0003] Upon inquiry, the publication number: CN220587715U discloses a student schoolbag with a burden-reducing function. In this technology, it is disclosed that "a student schoolbag with a burden-reducing function, which relates to the technical field of schoolbags. It includes a schoolbag body, shoulder straps, a waist belt and a back air cushion. There are two shoulder straps, and one end of each is connected to the schoolbag body, and the other end is connected to the side of the schoolbag body; the back air cushion is connected to the upper part of the back of the schoolbag body, and the waist belt is connected to the lower part of the back of the schoolbag body; the waist belt includes a waist belt support component and a covering and fitting pad, the waist belt support component is detachably connected to the back of the schoolbag body, and the covering and fitting pad is detachably connected to both sides of the waist belt support component" and other technical solutions, and has technical effects such as "the fitting degree between the schoolbag body and the human back can be adjusted through the back air cushion and the waist belt, reducing the pressure generated by the shoulder straps on the shoulders of students, making the schoolbag more comfortable to carry, thus effectively reducing the burden on the user, avoiding the burden on the user's body caused by the overweight schoolbag, and enhancing the practicality of the schoolbag";

[0004] The above solution only makes the schoolbag more comfortable to carry, thus improving the carrying experience of the user to a certain extent. However, it does not fundamentally solve the problem of reducing the weight of the schoolbag, which results in that even if the carrying feeling of the schoolbag is optimized, children still need to bear a heavy burden every day. In the long run, it may have an adverse impact on their physical health and growth and development. Summary of the Invention

[0045] In this embodiment, the exoskeleton component 12 can be integrally worn and fixed on the lower limbs through the thigh strap 126, the calf strap 127, the ankle strap 128, and the foot sole strap 129.

[0046] Specifically, the schoolbag component 11 further includes a chuck 114 fixed to the front surface of the upper end of the backpack 113, a card slot 115 opened at the upper end of the mounting hole 117 and cooperating with the chuck 114, a threaded head 116 fixed to the bottom of the backpack 113, a mounting hole 117 opened at the lower end of the mounting hole 117 and cooperating with the threaded head 116, a threaded knob 118 threadedly mounted on the threaded head 116, and a wearing member 119 provided at the front end of the back frame 111 for wearing on the upper limbs.

[0047] In this embodiment, when the backpack 113 is installed on the back frame 111, it is positioned by snapping the chuck 114 into the card slot 115. At the same time, the threaded knob 118 is also inserted into the mounting hole 117, and then the threaded knob 118 is rotated and tightened to fix the backpack 113 on the back frame 111; it is convenient to disassemble and assemble the backpack 113 when it needs to be cleaned.

[0048] Specifically, the wearing member 119 includes shoulder straps 1191 fixed to both ends of the back frame 111, a shoulder tightening device 1192 installed between the shoulder straps 1191 at both ends, waist belts 1193 fixed to both ends of the back frame 111, and a waist tightening device 1194 installed between the waist belts 1193 at both ends.

[0049] In this embodiment, when the standing and walking posture sensor 135 detects that the spinal curvature angle of the user is too large or exceeds the threshold, it can control the shoulder tightening device 1192 and the waist tightening device 1194 to respectively contract and adjust the shoulder straps 1191 and the waist belts 1193, improve the wearing comfort, and assist in correcting bad standing postures and preventing spinal curvature and lateral curvature.

[0050] Specifically, the monitoring system 13 includes a central controller 131 and a data processor 132 installed inside the back frame 111, a joint angle sensor 133 installed on the leg assistance module 121, a plantar pressure sensor 134 installed on the foot assistance module 122, a standing and walking posture sensor 135, an acceleration sensor 136, and a gyroscope 137 installed inside the back frame 111.

[0051] In this embodiment, gait data of the user during walking is collected by the joint angle sensor 133 and the plantar pressure sensor 134 for analyzing the user's walking habits; the standing and walking postures of the user are monitored by the standing and walking posture sensor 135, and information such as the degree of spinal curvature and the shoulder tilt angle of the user can be obtained in real time; the motion state of the user, such as walking speed and acceleration, is detected by the acceleration sensor 136 and the gyroscope 137, which helps to analyze the user's walking rhythm and step length.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
