Abstract
Description
Technical Field
[0001] This utility model relates to the field of backpack technology, and more specifically to a breathable and shape-forming backpack pad and backpack. Background Technology
[0002] Backpacks are a common household item, indispensable for travel and school commutes. To enhance comfort, backpacks often feature multiple layers of thick padding where they contact the back. This padding, typically made of materials like sponge or pearl cotton, provides some shock absorption. However, these materials offer extremely poor breathability. When wearing such a backpack outdoors or in hot weather, the lack of ventilation at the point of contact with the back leads to excessive sweating, soaking both clothes and the backpack, resulting in a very unpleasant carrying experience. Furthermore, once sweat seeps into the padding, it becomes difficult to clean thoroughly and dry quickly during backpack washing. Utility Model Content
[0003] The purpose of this invention is to provide a breathable and shape-forming backpack pad and backpack to solve the aforementioned problems in the prior art.
[0004] The present invention adopts the following technical solution:
[0005] A breathable and shape-forming backpack pad includes a back pad body, which is composed of several geometric grid layers from top to bottom. Several connecting posts are provided between the connected geometric grid layers. The edge of the back pad body is provided with an edge frame that connects to the back of the backpack. The geometric grid layers, connecting posts and edge frame are 3D printed as a single piece.
[0006] Furthermore, the geometric grid layer is divided into at least two layers from top to bottom. The edge of the uppermost geometric grid layer curves downward in an arc and is integrally formed with the edge frame. The edges of the other geometric grid layers extend to the curved edge of the uppermost geometric grid layer and are integrally formed with it.
[0007] Furthermore, the bottom of the lowest geometric grid layer is provided with several support tentacles for supporting the back of the backpack.
[0008] Furthermore, the two ends of the connecting column are located at the grid intersections of the geometric grid layer.
[0009] A backpack includes a backpack body, the back of which is provided with a plurality of the aforementioned backpack pads.
[0010] Furthermore, the edge frame is sewn inside the back of the backpack body, while the back pad body is exposed outside the back of the backpack body.
[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:
[0012] 1. The back pad body of this utility model is a lattice structure composed of multiple layers of geometric grid and connecting pillars, which makes the back pad body have excellent breathability. At the same time, it is preferably made of elastic material in 3D, which makes the back pad body have excellent shock absorption performance and comfortable contact feel.
[0013] 2. The lattice structure of the back pad and its direct exposure to the back of the backpack allow water to easily remove sweat and dirt that have seeped into the back pad during washing, making cleaning simple and thorough, and drying quick and convenient. Attached Figure Description

[0017] The components in the diagram are labeled as follows: backpack body 10, back pad body 20, geometric mesh layer 21, connecting post 22, edge frame 23, and top support foot 24. Detailed Implementation
[0018] The specific implementation of the present invention will now be described with reference to the accompanying drawings.
[0019] Reference Figure 1 and Figure 3 A breathable and shape-adjustable backpack pad and backpack are disclosed. The backpack pad includes a back pad body 20, and the backpack includes a backpack body 10. The back pad body 20 is composed of several layers of geometric grid layers 21 from top to bottom. Several connecting posts 22 are provided between the connected geometric grid layers 21, and the two ends of the connecting posts 22 are located at the grid intersections of the geometric grid layers 21. The edge of the back pad body 20 is provided with an edge frame 23 that connects to the back of the backpack. The geometric grid layers 21, connecting posts 22, and edge frame 23 are 3D printed as a single piece.
[0020] Reference Figure 1 The back of the backpack body 10 is provided with several backpack pads. In this embodiment, there are two backpack pads, which are symmetrically arranged along the central axis of the back of the backpack body 10. The backpack pads are made by printing them separately using existing 3D printing technology with elastic materials such as rubber. The edge frame 23 of the backpack pads is then sewn into the back of the backpack body 10, while the back pad body 20 with a geometric grid structure is exposed on the back of the backpack body 10 for contact with the back of the human body.
[0021] Reference Figure 2 and Figure 3 Specifically, the geometric mesh layer 21 of the back pad body 20 is divided into at least two layers from top to bottom, and in this embodiment, a three-layer geometric mesh layer 21 structure is preferred. The edge of the uppermost geometric mesh layer 21 is curved downwards in an arc and integrally formed with the edge frame 23. The edges of the other geometric mesh layers 21 extend to the curved edge of the uppermost geometric mesh layer 21 and are integrally formed with it. The bottom of the lowermost geometric mesh layer 21 is provided with several supporting tentacles 24 for supporting the back of the backpack. The supporting tentacles 24 are preferably integrally formed with the lowermost geometric mesh layer 21 by 3D printing. After the uppermost geometric mesh layer 21 is 3D printed, it can be slightly smoothed, as it is used for direct contact with the back of the human body. The supporting tentacles 24 of the lowermost geometric mesh layer 21 can serve as force fulcrums with the backpack body 10, increasing the friction with the back of the backpack body 10 and making its connection structure more stable.
[0022] Reference Figure 1 and Figure 3 When using this backpack, the back pad body 20 directly contacts the user's back. The back pad body 20 is a lattice structure composed of multiple geometric mesh layers 21 and connecting pillars 22, giving it excellent breathability. Simultaneously, its use of a preferred 3D elastic material provides superior shock absorption and a comfortable feel. Furthermore, its lattice structure and its direct exposure to the back of the backpack body 10 allow water to easily remove sweat and dirt that has seeped into the back pad body 20 during washing, making cleaning simple and thorough, and drying quick and convenient.
[0023] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
