Description

Technical Field

[0001] This utility model relates to the field of computer bag technology, and more specifically, to a lattice structure shockproof and cushioning computer bag. Background Technology

[0002] Laptop bags are a type of bag product that emerged with the widespread use of laptops. They belong to the category of 3C digital accessories and bags, and are mainly used to store laptops and documents.

[0003] Traditional laptop bags often use a single layer of fabric or a simple interlayer design, lacking a dedicated shock-absorbing structure. When faced with medium to high-intensity impacts, they cannot effectively disperse the impact force or absorb energy, easily leading to deformation of the laptop casing, screen breakage, and damage to internal components. Furthermore, they cannot comprehensively cover all risks associated with scratches, collisions, and impacts. Regarding stability, traditional products often rely on simple storage space or a single strap, allowing the laptop to easily slide left and right, move up and down, and tip over inside the bag. Especially in bumpy environments, the laptop is prone to colliding with the bag walls and accessories, causing secondary damage.

[0004] This invention can improve the protective, adaptability and practicality of computer bags, making them lighter and more breathable during use. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a lattice structure shockproof and cushioning computer bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lattice structure shockproof and cushioning computer bag, comprising: a bag body;

[0007] Handles are fixedly installed on both sides of the bag body;

[0008] A zipper is installed on the upper surface of the bag body;

[0009] A lattice plate, which is installed inside the package;

[0010] The package includes an outer layer and an inner layer, the lattice plate is located between the outer layer and the inner layer, and a partition is detachably installed inside the package.

[0011] A further preferred embodiment: Two fabric rings are sewn onto the inner wall of the bag, the two fabric rings being sewn onto the bottom and side of the inner wall of the bag respectively, and both fabric rings are provided with a binding strap.

[0012] A further preferred embodiment: the two ends of the strap are fixed with Velcro, and the computer is located outside the two fabric loops and fixed with the strap.

[0013] A further preferred embodiment: a limiting plate is movably connected inside the package body, the outer side of the limiting plate is fitted to the inner wall of the package body, and the limiting plate and the package body are detachably connected; one side of the partition is fitted to one side of the limiting plate, and the partition and the limiting plate are fixed together by Velcro.

[0014] A further preferred embodiment: the inner wall of the bag is sewn with a fixing strap, the two ends of the fixing strap can be fixed by Velcro, two through slots are opened on both sides of the limiting plate, and one end of the fixing strap passes through the through slot and is fixed to the other end.

[0015] A further preferred embodiment: the limiting plate is U-shaped.

[0016] A further preferred embodiment: the lattice plate is made of PVC / PU.

[0017] Beneficial effects:

[0018] 1. The design of the detachable and movable connection between the limiting plate and the bag body is highly advantageous. It can be flexibly adjusted according to the size of the computer, reducing or expanding the storage space. It can also be completely removed when the computer is not needed, freeing up space inside the bag and realizing the function of converting the computer bag into a regular storage bag to meet the needs of multiple scenarios. In addition, its Velcro linkage design with the divider makes the partition adjustment more efficient. When changing the size of the computer, the divider moves synchronously with the limiting plate without the need for separate operation. This ensures that the computer area and the accessory area are always tightly separated, preventing hard objects such as chargers from hitting the computer, reducing space waste, and improving the organization of the storage. At the same time, the operation does not require tools and can be completed with one hand, which significantly reduces the threshold of use.

[0019] 2. By incorporating straps that work in conjunction with fabric loops and channels, the stability of the laptop inside the bag is greatly enhanced. This restrains the laptop and effectively reduces its movement within the bag. Especially in the event of an accidental drop, it reduces the additional impact caused by displacement, lowering the risk of screen breakage and damage to internal components. In terms of ease of use, the straps use Velcro connections, eliminating the need for buckles, zippers, or other easily damaged parts. Tightening or loosening can be done with one hand, making operation efficient and convenient. They are also durable and resistant to damage even after repeated use, with a lifespan far exceeding that of ordinary adhesive straps. Furthermore, the straps are concealed within the bag's internal structure, preventing them from snagging clothing or interfering with components such as the lattice panel or zippers. This design strengthens the secure fit while maintaining a comfortable user experience and the overall aesthetic appeal of the bag.

[0020] 3. By incorporating a lattice plate, which serves as the core protective component for the laptop bag's shock absorption, the lattice plate, through its material properties and structural design, constructs a safety barrier for the laptop. In terms of protective performance, the lattice plate is made of PVC / PU material, combining rigidity and elasticity. PVC ensures structural support, preventing breakage under slight deformation when subjected to force, while PU can quickly rebound. The combination of the two provides a basic guarantee for cushioning. When impact forces come into contact, the lattice structure is decomposed into multi-directional components by the polyhedral units, preventing the concentrated impact force from acting on the laptop from a single point. At the same time, the lattice units convert kinetic energy into internal energy, significantly reducing the transmission of impact. It can effectively resist medium to high intensity impacts, reducing the risk of computer shell deformation, screen cracking, and damage to the motherboard and hard drive. Compared with ordinary single-layer cloth computer bags, its protective ability is significantly improved. In addition, the lattice plate is located between the outer and inner layers of the bag, forming a three-layer protective structure: the outer layer resists scratches and minor collisions, the lattice plate withstands medium to high intensity impacts, and the soft inner fabric avoids friction between the lattice plate and the computer, while absorbing minor vibrations. It is suitable for outdoor commuting, business trips and other scenarios where accidents are likely to occur. Moreover, the PVC / PU material is lightweight and waterproof, which is lighter than the metal protective plate and will not increase the burden on the bag. In case of accidental splashes, it can also reduce water seepage into the inner layer. At the same time, the lattice plate does not directly contact the external environment, which can reduce wear and aging and extend the service life, balancing protection and practicality.

[0021] 4. In summary, this lattice structure shockproof and cushioning laptop bag, through the setting of limiting plates and other structures, securely partitions the compartments, preventing accessories from colliding with the laptop. It is easy to operate, and the straps, cloth rings, and through slots work together with Velcro to form a double binding, which not only restricts the movement of the laptop but also locks the laptop in place with the limiting plates, preventing secondary collisions. The hidden design does not affect the use or aesthetics. The lattice plate, made of PVC / PU material and with a lattice structure as its core, disperses impact force and absorbs energy, resisting medium to high intensity impacts. Together with the outer and inner layers, it forms a three-layer protection, covering risks in all scenarios. At the same time, it is lightweight and waterproof, extending the lifespan of the bag and the laptop. The combination of these three features comprehensively improves the protection, adaptability, and practicality of the laptop bag. Attached Figure Description

[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0028] Please see Figure 1-4 In this embodiment of the present invention, a lattice structure shockproof and cushioning computer bag includes: a bag body 1; handles 2, which are fixedly installed on both sides of the bag body 1; a zipper 3, which is installed on the upper surface of the bag body 1; and a lattice plate 4, which is installed on the inner side of the bag body 1. The bag body 1 includes an outer layer 101 and an inner layer 102, and the lattice plate 4 is located between the outer layer 101 and the inner layer 102. A partition 6 is detachably installed inside the bag body 1. Two fabric rings 103 are sewn onto the inner wall of the bag body 1, and the two fabric rings 103 are respectively sewn onto the bottom and side of the inner wall of the bag body 1. A strap 104 is provided through each of the two fabric rings 103. The two ends of the strap 104 are fixed by Velcro. The computer is located outside the two fabric rings 103 and fixed by the strap 104. The lattice plate 4 is made of PVC / PU.

[0029] As the core anti-drop component of the case 1, the lattice plate 4, made of PVC / PU, works in conjunction with the lattice structure to provide cushioning. PVC (polyvinyl chloride) possesses a certain degree of rigidity and toughness, allowing it to deform slightly without breaking under stress. PU (polyurethane) is inherently elastic, quickly rebounding after deformation. The combination of the two ensures both structural support and basic cushioning capabilities. When subjected to external impact, the lattice structure dissipates the impact force in two ways: force dispersion and transmission: after the impact force contacts the surface of the lattice plate 4, it is decomposed into multiple directional components by the polyhedral units of the lattice, preventing the impact force from concentrating on the computer surface, such as during a drop. The single-point impact force is transmitted to the surrounding units through the edges of the lattice holes, significantly reducing the pressure. When subjected to force, the lattice units undergo compression and deformation, converting the kinetic energy of the impact into the internal energy of structural deformation, rather than directly transferring it to the computer, thus weakening the impact on the computer casing, screen, and internal components. The outer layer 101 of the enclosure 1 acts as the first barrier, mainly resisting scratches and minor collisions, such as friction and slight bumps during daily placement, preventing sharp external objects from directly contacting the lattice plate 4 or the inner layer 102. The lattice plate 4, located in the middle layer, receives medium to high-intensity impacts transmitted from the outer layer 101, such as drops and impacts, and absorbs them through buffering. The core impact force is neutralized by the principle of the inner layer 102, which directly contacts the computer surface. The material is usually soft fabric, such as velvet or cotton, to prevent scratches caused by friction between the lattice plate 4 and the computer casing, and to absorb any minor vibrations not completely neutralized by the lattice plate 4, such as slight shaking during transport, forming a dual protection of hard protection and soft fit. The displacement of the computer within the bag is a major cause of secondary damage; for example, if the computer impacts the bag walls during a drop, the removable partition 6 divides the interior of the bag 1 into a computer storage area and an accessory area, such as a charger and mouse, preventing accessories from colliding with the computer during transport. It can also be adjusted according to the computer's size. The partition 6 is designed to accommodate different computer models, reducing the space for horizontal and vertical movement of the computer. Two fabric loops 103 are sewn onto the bottom and side of the bag body 1, respectively, forming two-point restraints for the computer. The strap 104 passes through the fabric loops 103 and is tightened with Velcro, which can firmly fix the computer inside the bag body 1, preventing the computer from hitting the bag wall due to shaking when carried. The bottom fabric loop 103 restricts the vertical movement of the computer, so that the computer will fall when the bag is lifted. The side fabric loop 103 restricts the horizontal movement, so that the computer will tilt when the bag is placed on its side. Even if the bag body 1 is accidentally dropped, the computer can maintain a relatively stable position, reducing secondary collisions with the lattice plate 4 and the bag wall.

[0030] The design of the lattice plate 4 effectively resists medium to high-intensity impacts, reducing the risk of computer casing deformation, screen breakage, and damage to the internal motherboard and hard drive. The three-layer structure covers all scenarios, providing more comprehensive protection compared to ordinary single-layer cloth computer bags, making it especially suitable for outdoor commuting, business trips, and other scenarios prone to accidental drops. The two-point fixation of the cloth loop 103 and strap 104, along with the partitioning and limiting function of the removable divider 6, prevents the computer from sliding inside the bag, avoiding scratches from accessories on the computer casing or hidden damage caused by the computer impacting the bag walls. The PVC / PU lattice plate 4 combines durability and lightweight design, being lighter than metal protective plates without increasing the overall weight of the bag 1, and offering better waterproofing than ordinary cloth, reducing water penetration into the inner layer 102 in case of accidental splashes. The removable divider 6 allows for flexible adjustment of the internal structure. The bag's design accommodates laptops of various sizes and allows for compartmentalization to enhance storage efficiency. Handles 2 are fixed to both sides of the bag body 1, ensuring even weight distribution when lifting. A top zipper 3 facilitates quick and easy access to the laptop, while the Velcro straps 104 allow for easy securing and disassembly without tools. A lattice panel 4, located between the outer layer 101 and the inner layer 102, avoids direct contact with the external environment, reducing wear and tear. The fabric construction of the outer and inner layers further enhances breathability and lightness. The Velcro straps 104, connected by Velcro, are durable and long-lasting compared to ordinary adhesive straps 105. This combination of practicality and durability makes it particularly suitable for users with high demands for laptop protection.

[0031] In this embodiment of the utility model, a limiting plate 5 is movably connected inside the package body 1. The outer side of the limiting plate 5 is attached to the inner wall of the package body 1, and the limiting plate 5 and the package body 1 are detachably connected. One side of the partition 6 is attached to one side of the limiting plate 5, and the partition 6 and the limiting plate 5 are fixed with Velcro. A fixing strap 105 is sewn to the inner wall of the package body 1. Both ends of the fixing strap 105 can be fixed with Velcro. Two through slots 501 are opened on both sides of the limiting plate 5. One end of the fixing strap 105 passes through the through slot 501 and is fixed to the other end. The limiting plate 5 is U-shaped.

[0032] One end of the fixing strap 105 first adheres to the inner wall of the bag body 1, and the other end passes through the through slots 501 on both sides of the limiting plate 5. It is then tightened and fixed to its other end using Velcro. During this process, the fixing strap 105 firmly pulls the limiting plate 5 taut and adheres it to the inner wall of the bag body 1, preventing the limiting plate 5 from shifting due to shaking or falling of the bag body 1. This effectively divides the laptop bag into two cavities. The partition 6 is fixed to the limiting plate 5 using Velcro, achieving synchronous adjustment and stable separation between the laptop compartment and the accessory compartment. The adhesive fixation of the Velcro prevents relative sliding between the partition 6 and the limiting plate 5. Even if the bag body 1 shakes violently, items such as chargers and mice in the accessory compartment will not knock open the partition 6 and enter the laptop compartment. Simultaneously, the partition 6 provides additional support for the limiting plate 5, preventing slight deformation of the "U"-shaped limiting plate 5 due to stress. For situations requiring high-strength protection, such as carrying a laptop on outdoor business trips... The upper limit plate 5 and fixing strap 105 are installed to strengthen the fixation; when the computer is not in use, the upper limit plate 5 can be removed to expand the storage space, making it a dual-purpose item with significantly improved practicality; the Velcro fastening between the divider 6 and the upper limit plate 5 creates a rigid separation between the computer area and the accessory area, preventing hard objects such as chargers and data cables from being knocked open by the bag body 1 and scratching the computer shell; the connection between the fixing strap 105 and the upper limit plate 5 only requires Velcro, eliminating the need for buckles, zippers 3, or other easily damaged structures, allowing for tightening or loosening with one hand; the detachable design of the upper limit plate 5 and the bag body 1 allows for easy disassembly and assembly without tools, making operation simple; the fixing strap 105 is hidden between the upper limit plate 5 and the bag body 1, preventing it from being exposed and snagging clothing, and it does not interfere with components such as the lattice plate 4 or zippers 3, balancing protection and user experience; further improving the flexibility of using the computer bag.
