DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Those skilled in the art can understand that, unless specifically stated, the singular forms "a", "an" and "said" used herein also include the plural forms. It should be further understood that the word "comprise" used in the specification of the present application means that the features, integers, steps, operations, elements and / or components exist, but does not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0025] Please refer to Figures 1-4 As shown, a weight-reducing child backpack is provided, which comprises a backpack 1 and shoulder straps 2, and a weight reduction and spine protection mechanism 3 is arranged on the side close to the human back of the backpack 1.

[0026] The weight reduction and spine protection mechanism 3 comprises a first weight reduction pad 4, a second weight reduction pad 5 and a third weight reduction pad 6 from top to bottom, wherein the first weight reduction pad 4 and the third weight reduction pad 6 are fixedly connected with the backpack 1, a limiting rail 7 and a positioning rod 8 are arranged between the first weight reduction pad 4 and the third weight reduction pad 6, the second weight reduction pad 5 can move up and down along the limiting rail 7 and the positioning rod 8, a positioning bolt 9 is matched on the positioning rod 8, limiting blocks and holes corresponding to the limiting rail 7 and the positioning rod 8 are formed on the second weight reduction pad 5, the positioning bolt 9 comprises two and is threadedly connected with the positioning rod 8, and the second weight reduction pad 5 moves between the two positioning bolts 9. Here, the position of the second weight reduction pad 5 can be adjusted by adjusting the distance between the two positioning bolts 9, so as to better fit the actual situation of different people.

[0027] The first weight reduction pad 4, the second weight reduction pad 5 and the third weight reduction pad 6 are arranged in mirror image with the human spine as the center line, wherein the first weight reduction pad 4 and the second weight reduction pad 5 gradually thin on the side close to the human spine. Because the spine of the human body has a certain protrusion on the back, the side close to the spine is thinned to better fit the back and reduce the extrusion on the spine, thereby reducing the weight borne by the spine. A waist drag 10 is installed between the two third weight reduction pads 6.

[0028] When wearing this application, the weight of the backpack is applied to the back of the human body through the first weight-reducing pad 4, the second weight-reducing pad 5, and the third weight-reducing pad 6, rather than directly to the spine. It is also important to note that the first weight-reducing pad 4, the second weight-reducing pad 5, and the third weight-reducing pad 6 themselves have a certain thickness, curvature, and curved surface 11. This can more stably and evenly distribute the weight of the backpack to other areas of the back. Through reasonable shoulder and waist support design, it can increase back ventilation, reduce friction, improve wearing experience, and achieve a good spinal protection effect while ensuring spinal health.

[0029] like Figures 1-3 As shown:

[0030] In this embodiment, the first weight-reducing pad 4, the second weight-reducing pad 5, and the third weight-reducing pad 6 are all provided with curved surfaces 11 that conform to the human body; from top to bottom, the three curved surfaces 11 respectively correspond to the shoulders, both sides of the back, and both sides of the waist, that is, the curved surface 11 on the first weight-reducing pad 4 corresponds to the shoulders, the curved surface 11 on the second weight-reducing pad 5 corresponds to both sides of the back, and the curved surface 11 on the third weight-reducing pad 6 corresponds to both sides of the waist. Figure 3 As can be seen, the curves of the three curved surfaces 11 are all different. Figure 3 and Figure 4 It can also be seen that the third weight-reducing pad 6 protrudes differently from the first weight-reducing pad 4 and the second weight-reducing pad 5, which can help the wearer straighten their chest and reduce the weight borne by the spine.

[0031] In this embodiment, the waist support 10 is specifically a hollow semi-cylindrical structure. The arched surface of the waist support 10 faces the waist of the human body. The waist support 10 is also provided with staggered ventilation holes 12. The waist support 10 is made of soft rubber material, which makes it soft and elastic. The ventilation holes 12 are pentagonal structures, but can also be circular, square, or other polygonal structures.

[0032] like Figures 3-4 As shown:

[0033] In this embodiment, the first pressure-reducing pad 4 and the second pressure-reducing pad 5, which are mirrored, form a gap in the longitudinal direction. The gap is a pressure-free area. When worn, the human spine is in this pressure-free area. Moreover, this pressure-free area can also be used as an air passage, which not only improves the protection and comfort of the spine, but also enhances the ventilation effect of the back, which helps to promote air circulation and avoid sweat accumulation.

[0034] In order to further increase the ventilation effect of the application, the first, second and third load-reducing pads 4, 5 and 6 are made of flexible plates of EVA material, the surface of which is covered with a breathable mesh. EVA is a copolymer of ethylene and vinyl acetate, which has good cushioning, heat insulation, ventilation, moisture resistance and sweat absorption effects. The flexible plate made of EVA material not only can be bent according to the curve of the human back, but also has a high ventilation effect, which further increases the ventilation effect and comfort of the bag. Furthermore, the breathable mesh can avoid direct contact between the EVA material and the human body, reducing friction.

[0035] In the present embodiment, the first, second and third load-reducing pads 4, 5 and 6 form gaps in the horizontal direction, which constitute gas flow channels. On the basis of the vertical air flow channels, the two cooperate to realize multidirectional air flow, thereby achieving better back ventilation effect.

[0036] The basic principles, main features and advantages of the present application have been shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
