Description

Technical Field

[0001] This application relates to the field of school bags, and in particular to a biomimetic-structure-based school bag carrying system that protects a child's spine. Background Technology

[0002] For students who frequently carry heavy loads, backpacks can easily damage the spine over time, affecting normal bone development and causing injury to the spine and muscles. The spine is the most important support structure in the human body and is also where the Du meridian runs, making it crucial for overall health, especially for students whose bodies are still developing.

[0003] Currently, most backpacks on the market protect the spine through the following technologies:

[0004] Traditional back braces use rigid materials (such as plastic or metal) to conform to the curves of the back, but lack dynamic adjustment capabilities, and prolonged use can easily lead to localized pressure concentration.

[0005] Pressure-reducing shoulder strap design: such as S-shaped wide shoulder straps combined with chest buckles for fixation, although it can distribute shoulder pressure to a certain extent, the differences in children's body shapes are large, and it is not suitable for children of different body shapes. In addition, it has poor breathability and insufficient comfort.

[0006] Lightweight materials reduce the burden by lowering the weight of the backpack, but do not solve the problem of uneven weight distribution. For example, ordinary thin sponge back pads are prone to collapse, causing pressure on the spine. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model provides a schoolbag carrying system based on a biomimetic structure. Through dynamic pressure distribution, adaptive adjustment, and a breathable structure, it solves the problem of insufficient back support function in traditional schoolbags, achieving a system that simultaneously improves load reduction, back support, and comfort. The specific technical solution is as follows:

[0008] A backpack carrying system based on a biomimetic structure, characterized in that:

[0009] It includes a back body connected to the bag body, the back body is provided with a first module and a second module that are symmetrical to each other, a third module disposed between the first module and the second module, and a fourth module is provided below the three modules;

[0010] The first module and the second module are divided into four groups of pressure modules from top to bottom to form a biomimetic support structure for conforming to the physiological curvature of the spine, and the contact area ratio of the four groups of pressure modules is 3:4:2:3.

[0011] This technical solution sets the entire back frame as a segmented pressure-distributing module with left and right symmetry. At the same time, through non-uniform contact area and segmented design, vertical pressure is distributed laterally, reducing single-point pressure, thereby solving the problem of reducing the burden on the spine, protecting the spine and improving comfort when carrying heavy objects.

[0012] Preferably, the four-component pressure modules are divided into a first-component pressure module, a second-component pressure module, a third-component pressure module, and a fourth-component pressure module by dividing lines;

[0013] The gap between the first component pressure module and the second component pressure module is 1 cm.

[0014] This technical solution divides the first and second modules into four pressure-reducing modules using dividing lines, forming a biomimetic support structure that better conforms to the physiological curvature of the spine. Simultaneously, the gaps between the first and second pressure-reducing modules are set to a certain width, providing a heat dissipation channel to reduce temperature.

[0015] Preferably, the dividing lines between the four pressure modules are all straight lines or arc lines, and the dividing lines are arranged in parallel to form a breathable channel.

[0016] In this technical solution, the dividing lines are set as straight lines or arcs, and the parallel arrangement of the dividing lines is mainly to provide air circulation channels and improve heat dissipation efficiency.

[0017] Preferably, the fourth module has a trapezoidal structure that is narrower at the top and wider at the bottom, and is divided into two parts from top to bottom.

[0018] In this technical solution, the fourth module is designed as a trapezoidal structure that is narrower at the top and wider at the bottom, and is divided into two parts from top to bottom. The purpose is to better fit the physiological curvature of the spine, ensure that the support force is dynamically adjusted with pressure, and at the same time, an air circulation channel is formed between the upper and lower parts to improve heat dissipation efficiency.

[0019] Preferably, the first module, the second module, and the fourth module are all composed of high resilience memory foam and a 3D mesh breathable material layer covering the outside of the high resilience memory foam.

[0020] The third module is a long, narrow groove, and forms a ventilation groove with the first module, the second module, and the fourth module.

[0021] In this technical solution, the third module is preferably set as a long strip-shaped groove. In this way, the connection with the other modules not only achieves the support function, but also forms a three-dimensional ventilation channel, and also takes into account the optimization of strength and weight.

[0022] This application includes at least one of the following technical effects:

[0023] (1) By using a biomimetic structure, the shoulder pressure is distributed to the lower back, and the measured pressure distribution uniformity significantly reduces the spinal load.

[0024] (2) The non-uniform segmented back panel structure can cover more than 90% of the back body shape, and its adaptability is better than the traditional fixed back panel design.

[0025] (3) The breathable structure and breathable materials allow the back contact surface to cool down quickly, reducing stuffiness and reducing overall weight. Attached Figure Description

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0036] In Embodiment 1 of this application, as Figure 1-2 As shown, this embodiment provides a backpack carrying system based on a biomimetic structure. This carrying system is mainly designed as a back piece connected to the backpack body on the back of the backpack. The back piece has a first module 1 and a second module 2 that are symmetrically arranged on both sides, and a third module 3 located between the first module 1 and the second module 2. At the same time, a fourth module 4 is also set below the above three modules. On this basis, the first module 1 and the second module 2 that are symmetrically arranged on both sides are further divided into four sub-modules from top to bottom. The purpose is to make the overall shape of the back piece structure into a biomimetic support structure through the division of the back piece structure, so as to better conform to the physiological curvature of the human spine. More importantly, the contact area ratio of each sub-module is set in 3:4:2:3, that is, the area ratio of the first sub-module 11, the second sub-module 12, the third sub-module 13, and the fourth sub-module 14 is 3:4:2:3. The purpose is to achieve the horizontal distribution of vertical pressure through the non-uniform contact area of ​​the back piece through the segmented design, reduce the pressure at a single point, and thus solve the problem of reducing the burden on the spine, protecting the spine, and improving comfort when carrying heavy objects.

[0037] In the above embodiments, see Figure 1As shown, the first pressure module 11, the second pressure module 12, the third pressure module 13, and the fourth pressure module 14 are separated by dividing lines. Since the first pressure module 11 and the second pressure module 12 are located on the back where sweating is likely, they are separated by two dividing lines. Specifically, from top to bottom, the first dividing line 15, the second dividing line 16, the third dividing line 17, and the fourth dividing line 18 are set. At the same time, the gap between the first dividing line 15 and the second dividing line 16 is set to about 1 cm, so that the first pressure module 11 and the second pressure module 12 form a relatively wide heat dissipation channel, allowing the sweaty area on the back of the body to cool down quickly and preventing sweat from flowing out.

[0038] Of course, in the actual design, the first dividing line 15, the second dividing line 16, the third dividing line 17, and the fourth dividing line 18 are all straight lines or arcs, and each dividing line is arranged in parallel to form parallel ventilation channels. This not only makes the appearance beautiful, but also provides a fast air circulation path, effectively improving heat dissipation efficiency.

[0039] In the above embodiments, see again Figure 1 Preferably, the fourth module 4 in the back support is designed as a trapezoidal structure, narrower at the top and wider at the bottom, and is further divided into two parts from top to bottom by a fifth dividing line 19. The purpose is to better conform to the physiological curvature of the spine, ensure that the support force is dynamically adjusted according to pressure, and form an air circulation path between the upper and lower parts to improve heat dissipation efficiency.

[0040] In practical use, the first module 1, the second module 2, and the fourth module 4 are all composed of high-resilience memory foam and a 3D mesh breathable material layer covering the outside of the high-resilience memory foam. This not only utilizes the characteristics of the material to improve breathability and reduce the stuffiness of the back, but also achieves a balance between strength and weight optimization through the combination of high-resilience memory foam and 3D mesh breathable material layer.

[0041] In other embodiments, further optimizations are made based on the above embodiments. The third module 3 is set as a long strip-shaped groove. At the same time, the first module 1, the second module 2, and the third module 3 are combined with a combination of high-resilience memory foam and 3D mesh breathable material layer. This allows the edge of the first module 1 to naturally form a groove after connecting with the other modules, and the connection point forms a breathable groove. This not only achieves the support function, but also forms a three-dimensional ventilation channel, satisfying both strength and weight requirements.

[0042] This application achieves the following through the above embodiments:

[0043] (1) By dividing the non-uniform contact area of ​​the back, the pressure distribution uniformity is improved by 40%, which significantly reduces the spinal load.

[0044] (2) By dividing the first module 1 and the second module 2 in the back body, a biomimetic support structure is formed, so that the overall structure can better fit the physiological curvature of the human spine, further protecting the spine and improving the comfort of use.

[0045] (3) By improving the module material, the overall weight is reduced while the strength is guaranteed and the air permeability is improved.

[0046] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0047] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
