AI Technical Summary
[0003]目前的背包结构相对较为单一，唯一的创新性主要来自于各种外观设计，同时还有一些事对于存储空间的布局设计，当然，无论何种设计和改进，其主要功能还是用于装各种物品的，然而，在实际使用的时候，需要在背包之中找寻各种物品的时候，大件物品还好一点，打开背包便可以直接看到进行拿取，而对于一些较小的物品来说，在找寻的时候，往往都是手深入到背包之中，进行各种摸索，更甚者需要把背包之中的物品全部倒出来进行找寻，较为麻烦，不易找到，且对存储物品造成杂乱的问题
[0012]该背包，首先以链贴料的方式来使用，具体结构不会造成背包外观的累赘或改变，照明灯置于上部链贴料中，能够实现自上而下照亮整个内部空间，不同于现有技术中光源仅固定在内衬上，容易妨碍使用或照明不均，照明灯具有特殊形态——扁平而紧凑，不造成阻碍，同时磁性固定确保稳固安装和便捷拆卸，以便通过外置USB接口进行充电。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of backpack technology, specifically a backpack. Background Technology
[0002] Backpacks are primarily used as storage devices for various items. Students use them to store books and school supplies, while in daily life, they are mainly used to carry various personal items such as clothes, mobile phones, wallets, cosmetics, chargers, tissues, etc.
[0003] Current backpack structures are relatively simple, with the only innovations mainly coming from various appearance designs and storage space layouts. Of course, regardless of the design and improvements, their primary function is still to carry various items. However, in actual use, when searching for items in a backpack, large items are relatively easy to find by simply opening the backpack. But for smaller items, searching often requires reaching deep into the backpack and groping around, or even emptying the entire backpack to find them, which is quite troublesome, difficult to locate, and creates clutter.
[0004] Therefore, we propose a knapsack problem to solve the above-mentioned problem. Utility Model Content
[0005] The purpose of this invention is to provide a backpack to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A backpack includes a backpack body structure. The top of the backpack body structure is an open design, and a zipper structure is sewn onto the inner wall of the arc-shaped opening structure. A chain patch is detachably installed at the opening position at the top of the backpack body structure. A magnetic disk is provided at the bottom center of the chain patch and is hidden in the inner lining layer. The magnetic disk is hidden in the inner lining layer of the chain patch and cannot be seen from the outside. A lighting structure is attached to the magnetic disk.
[0008] Preferably, the width and length of the chain patch are both greater than the segment and length of the opening on the backpack body structure, and zipper structures are sewn on both sides of the bottom of the chain patch. The chain patch can be detachably installed at the top position of the backpack body structure through the zipper structure.
[0009] Preferably, the magnetic disk is a strong magnetic sticker structure, with an adsorbable iron sheet structure fixedly bonded to the top of the lighting structure.
[0010] Preferably, the light source of the lighting structure faces downwards, the lighting structure is a rechargeable lamp device, and a button for switching on and off is provided on the lighting structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This backpack uses a chain-attached material, and its structure does not make the backpack look bulky or change. The light is placed in the upper chain-attached material, which can illuminate the entire interior space from top to bottom. Unlike the existing technology where the light source is only fixed to the lining, which can easily hinder use or cause uneven lighting, the light has a special shape - flat and compact, which does not cause obstruction. At the same time, magnetic fixation ensures a secure installation and easy disassembly, so that it can be charged via an external USB interface. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the chain-attached material structure of this utility model.
[0015] In the diagram: 1. Backpack body structure; 2. Chain strap material; 3. Magnetic disc; 4. Lighting structure. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides a backpack technical solution:
[0018] Example:
[0019] The backpack mainly includes a backpack body structure 1. The top of the backpack body structure 1 is an open design, and a zipper structure is sewn on the inner wall of the arc-shaped opening structure. A chain patch 2 can be detachably installed at the opening position at the top of the backpack body structure 1. A magnetic disc 3 hidden in the inner lining layer is set at the bottom center of the chain patch 2. A lighting structure 4 is attached to the magnetic disc 3.
[0020] The width and length of the chain patch 2 are both greater than the width and length of the opening on the backpack body structure 1, and zipper structures are sewn on both sides of the bottom of the chain patch 2. The chain patch 2 can be detachably installed on the top position of the backpack body structure 1 through the zipper structure.
[0021] Specifically, the magnetic disk 3 is a strong magnetic adhesive structure, with an adsorbable iron sheet structure fixedly bonded to the top of the lighting structure 4.
[0022] The light source of the lighting structure 4 faces downwards. The lighting structure 4 is a rechargeable lamp device and is equipped with a button for switching on and off.
[0023] In this embodiment, when in use, the fully charged light structure 4 is directly attached to the magnetic disk 3. Of course, before that, the entire chain patch 2 needs to be installed onto the backpack body structure 1 using a zipper structure, thereby forming a sealed space for the backpack body structure 1 to ensure basic storage function.
[0024] When you need to search for items in your backpack, open the backpack zipper and then choose to turn on or off the lighting structure 4 according to the light requirements. In this technical solution, we take turning on the lighting structure 4 as an example. Turn on the lighting structure 4 by using the switch button. The light from the lighting structure 4 illuminates from top to bottom, providing sufficient lighting for the backpack and making it easier to search for items.
[0025] This technical solution first uses the chain patch material 2. The specific structure will not cause any burden or change to the appearance of the backpack. The light is placed in the upper chain patch material, which can illuminate the entire internal space from top to bottom. Unlike the existing technology where the light source is only fixed on the lining, which can easily hinder use or cause uneven lighting, the light has a special shape - flat and compact, which does not cause obstruction. At the same time, the magnetic fixation ensures a stable installation and easy disassembly, so that it can be charged through the external USB interface.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
