Specifically, the embodiment of the present invention improves and describes the specific implementation structure of the schoolbag, and based on this, a more optimized Set the setting position of the function module.

具体的，所述包体可拆卸地连接在所述背负***上。具体的，包体的基本功能是用于容纳物品，实际实施中，根据用户所需的书包容量的不同，包体应该是可调节的，从而应对各种用户的需求。Specifically, the bag body is detachably connected to the carrying system. Specifically, the basic function of the bag body is to accommodate items. In actual implementation, the bag body should be adjustable according to the different capacity of the school bag required by the user, so as to meet the needs of various users.

进一步的，由于包体可拆卸的设置在背负***上，相应的，包体的重量是从连接位置传递至背负***，然后再通过背负***落在人体上；因此，所述包体与所述背负***的每一个连接位置上设置有一个所述重力传感模块。相对应的，为了设置重力传感模块，需要在包体与背负***之间设置相应的连接结构3。具体的，连接结构3可根据背垫和包体的结构进行设计。Further, since the bag body is detachably arranged on the carrying system, correspondingly, the weight of the bag body is transferred from the connection position to the carrying system, and then falls on the human body through the carrying system; One of the gravity sensing modules is arranged on each connection position of the carrying system. Correspondingly, in order to set the gravity sensing module, a corresponding connection structure 3 needs to be set between the bag body and the carrying system. Specifically, the connection structure 3 can be designed according to the structure of the back pad and the package body.

进一步的，所述背垫2包括具有预设强度且可弹性变形的背垫骨架10和背垫覆盖材料11；所述背垫骨架10在平面上按照预设形状加工形成，背垫材料填充所述背垫骨架10中的空区并覆盖在所述背垫骨架10的表面上。Further, the back pad 2 includes a back pad frame 10 with a preset strength and elastic deformation and a back pad covering material 11; the back pad frame 10 is processed and formed in a predetermined shape on a plane, and the back pad material is filled with the back pad material. The empty area in the back pad frame 10 is covered and covered on the surface of the back pad frame 10 .

具体的，背垫骨架10具有预设的强度，该预设的强度是指背垫骨架10相对于传统的如海绵、乳胶等背垫覆盖材料11是较硬的材料，但同时，该背垫骨架10是可弹性变形的，具体的，能够驱动背垫骨架10的变形作用力的大小可通过骨架材料的截面积进行调整，针对不同年龄的使用者进行适当调整。背垫骨架10的主要作用是用于通过较为硬质的材料对包体传递至背负***上的重量进行分散，避免包体的重量无限制的直接通过背负***作用在人体上。Specifically, the back pad frame 10 has a preset strength, which means that the back pad frame 10 is a harder material than the traditional back pad covering materials 11 such as sponge and latex, but at the same time, the back pad frame 10 is a harder material. The frame 10 is elastically deformable. Specifically, the magnitude of the deformation force capable of driving the back pad frame 10 can be adjusted by the cross-sectional area of the frame material, and can be adjusted appropriately for users of different ages. The main function of the back pad skeleton 10 is to disperse the weight transferred from the bag to the carrying system through a relatively hard material, so as to prevent the weight of the bag from directly acting on the human body through the carrying system without limitation.

此外，本发明实施例的背垫骨架10的设计结构可根据使用者的背部曲线进行设计，即对于人体背部的重点负重位置，背垫骨架10的空隙率可较小，对于人体背部的非重点负重位置，背垫骨架10的孔隙率可较大，以适当对重量进行分配并将重量调整至合适负重的位置上。In addition, the design structure of the back pad frame 10 according to the embodiment of the present invention can be designed according to the back curve of the user, that is, for the important load-bearing positions on the back of the human body, the void ratio of the back pad frame 10 can be smaller, and for the non-critical positions on the back of the human body In the load-bearing position, the porosity of the back pad frame 10 can be relatively large, so as to properly distribute the weight and adjust the weight to a suitable load-bearing position.

具体的，在人体背部上分布着肌肉和骨头这两大重要的支撑结构，对于书包的背负而言，主要的支撑部分应该落于肌肉上，且骨头不适宜与较硬的结构相接触；此外，由于人体的背部表面形状是随着人体姿势的变化而变化的，关于背垫骨架10的设计结构仅能是区域性的调整。Specifically, two important supporting structures, muscles and bones, are distributed on the back of the human body. For the carrying of a schoolbag, the main supporting part should fall on the muscles, and the bones are not suitable for contacting with hard structures; in addition, , since the shape of the back surface of the human body changes with the change of the posture of the human body, the design structure of the back pad frame 10 can only be adjusted regionally.

具体的，本发明实施例所述的空隙率具体是指，背垫骨架10是具有若干个通孔的孔隙结构，通孔的密度情况影响着对应位置上的背垫骨架10的支撑强度，通过增加通孔的密度的方式可以相对增加对应区域的背垫骨架10的柔软性，使该区域的分布力更均匀，压力更小。Specifically, the void ratio in the embodiment of the present invention specifically refers to that the back pad frame 10 has a pore structure with several through holes, and the density of the through holes affects the support strength of the back pad frame 10 at the corresponding position. The way of increasing the density of the through holes can relatively increase the flexibility of the back pad frame 10 in the corresponding area, so that the distribution force in this area is more uniform and the pressure is lower.

具体的，背垫骨架10的作用还包括拉伸张紧作用，具体的，背垫骨架10通过变形拉伸的方式，使作用力能够更好的覆盖在人体背部。相应的，背垫骨架10的变形拉伸会带动其上的背垫覆盖材料11的拉伸，尽可能的降低人体的支撑负担。Specifically, the function of the back pad frame 10 also includes a stretching and tensioning effect. Specifically, the back pad frame 10 can better cover the back of the human body by deforming and stretching. Correspondingly, the deformation and stretching of the back pad frame 10 will drive the stretching of the back pad covering material 11 thereon, thereby reducing the support burden of the human body as much as possible.

具体的，在背垫骨架10的表面和通孔中均会覆盖和填充柔软的背垫覆盖材料11，以进一步提高压力在背部的分布均匀性。Specifically, the surface and through holes of the back pad frame 10 are covered and filled with a soft back pad covering material 11 to further improve the uniformity of pressure distribution on the back.

需要说明的是，现有技术通常采用硬质背板的方式来实现相近似的功能，但在具体实践中发现，由于整体硬质背板与用户背部轮廓的贴合性较差，不能起到有效的应力分散的作用。It should be noted that, in the prior art, a hard backplane is usually used to achieve similar functions, but in specific practice, it is found that due to the poor fit between the overall hard backplane and the user's back profile, it cannot function. Effective stress dispersion effect.

For the user, when the weight is slightly heavy, the force of the schoolbag acts on the shoulder strap, and the user has to bend The back uses the spine to hold up the schoolbag. Compared with the normal vertebral curvature structure, the carrying action of the schoolbag will greatly affect the user's health.

因此，本发行实施例的所述背垫骨架10包括第一背垫骨架10和第二背垫骨架10；所述背垫在所述第一背垫骨架10和第二背垫骨架10之间沿竖向留有脊椎间隙；所述第一背垫骨架10和第二背垫骨架10之间基于位于所述脊椎间隙中的背垫覆盖材料11连接。具体的，将背垫骨架10分割为第一背垫骨架10和第二背垫骨架10的目的在于，避免大部分包体的重量落于人体的脊椎上，减小人体脊椎上的重量负担，人体无需通过曲背的方式提高背负力(通过曲背的方式也无法更好的分担作用力)，可被动的校正使用者的背姿；同时，可避免脊椎上的骨头受到太大的作用力导致伤痛。Therefore, the back pad frame 10 in the embodiment of this issue includes a first back pad frame 10 and a second back pad frame 10 ; the back pad is between the first back pad frame 10 and the second back pad frame 10 A spinal space is left in the vertical direction; the first back cushion frame 10 and the second back cushion frame 10 are connected based on the back cushion covering material 11 located in the spinal space. Specifically, the purpose of dividing the back pad frame 10 into the first back pad frame 10 and the second back pad frame 10 is to prevent most of the weight of the package from falling on the spine of the human body and reduce the weight burden on the spine of the human body. The human body does not need to increase the carrying force by bending the back (the force cannot be better shared by bending the back), and can passively correct the user's back posture; at the same time, it can prevent the bones on the spine from being subjected to too much force cause pain.

关于第一背垫骨架10和第二背垫骨架10之间的材料和结构，主要需要考虑到背垫与脊椎之间的贴合性以及人体的舒适性问题，具体的，所述第一背垫骨架10和第二背垫骨架10之间的背垫覆盖材料11上开有若干个通孔，以提高脊椎区域的透气性，具体的，还可以将所述第一背垫骨架10和第二背垫骨架10之间的背垫覆盖材料11为弹性变形材料，利用弹性变形材料的变形特性，使重量更为均匀充分的落在脊椎区域上，避免对脊椎造成太大的压力负担。Regarding the material and structure between the first back pad frame 10 and the second back pad frame 10, it is mainly necessary to consider the fit between the back pad and the spine and the comfort of the human body. Specifically, the first back pad Several through holes are opened on the back pad covering material 11 between the pad frame 10 and the second back pad frame 10 to improve the air permeability of the spine area. The back pad covering material 11 between the two back pad skeletons 10 is an elastically deformable material. Using the deformation characteristics of the elastically deformable material, the weight can fall on the spine area more evenly and fully, so as to avoid too much pressure burden on the spine.
