As the primary carrier for these devices, the function of laptop bags is no longer limited to basic storage; their protective performance, portability, and space utilization have gradually become core factors of concern for users. Currently, the market offers a wide variety of laptop bags, covering various carrying methods such as hand-held, shoulder, and backpack designs, and generally featuring different storage areas to meet users' needs for categorizing and storing accessories such as laptops, power adapters, and mice. However, traditional laptop bags still rely on single cushioning materials, such as sponge and foam, for shockproof design, especially considering the impacts and vibrations that electronic devices may encounter during transport. They lack multi-dimensional, three-dimensional protective structures and are unable to meet the multiple protection needs in complex environments.

[0003] In the existing technology, the shockproof structure of traditional computer bags is simple and the protection dimensions are limited. They mostly rely on local cushioning materials and lack a three-dimensional dispersion and absorption mechanism for multi-angle impacts from the top, bottom and sides. They are difficult to cope with rigid collisions during violent shaking or accidental drops, which can easily lead to wear and tear on the device shell or damage to the internal hardware.

[0027] like Figure 1-5 As shown, this preferred embodiment provides a multi-functional shockproof laptop bag, comprising:

[0028] The bag body 100 has a first zipper 102 and a second zipper 103 installed on its side. A handle 105 and a chain 104 are provided on the side of the bag body 100. A first storage module includes a first storage chamber 200, a shock-absorbing pad 204, a third zipper 202, a key fob 201, and a first mesh pocket 203. The first storage module is located inside the bag body 100. The shock-absorbing pad 204 is located on the inner wall of the bag body 100. The third zipper 202 controls the opening and closing of the first mesh pocket 203. The key fob 201 is located on the inner wall of the bag body 100. The area between the first mesh pocket 203 and the inner wall of the bag body 100 is the first storage chamber 200. A second storage module includes: a first zipper 102, a second zipper 103, a handle 105, and a chain 104. The second storage module is located inside the bag body 100, including a second storage chamber 300, a cushioning pad 340, a telescopic support 330, a second mesh bag 310, and an elastic band 320. The second storage module is located inside the bag body 100, the cushioning pad 340 is located inside the second mesh bag 310, the telescopic support 330 is located inside the second storage chamber 300, the second mesh bag 310 is connected to the side wall of the second storage chamber 300, and the elastic band 320 is located inside the second storage chamber 300. The third storage module includes a groove 401 and a restraining strap 402, which are located between the first storage chamber 200 and the second storage chamber 300. The first channel 101 and the second channel 107 are both located on the bag body 100.

[0029] It should be noted that the chain 104 can be connected to an adjustable crossbody shoulder strap. Both the handle 105 and the adjustable crossbody shoulder strap can be used to choose different carrying methods. There is also a blank area on the left side of the first storage compartment 200, which is used to install the shock-absorbing pad 204. The first storage compartment 200 can be used to store the computer's keyboard and mouse. The second storage compartment 300 is used to place the computer. The second mesh pocket 310 also has a certain cushioning effect. The shock absorption module controls the computer installed in the second storage compartment 300 through the telescopic bracket 330 to prevent the computer from shaking in the plane direction within the second storage compartment 300. The shock-absorbing pad 204 and the cushioning pad 340 work together to reduce shaking in the direction perpendicular to the second storage compartment 300 or the first storage compartment 200. The telescopic bracket 330 and the elastic band 320 are both set at the four corners of the second storage compartment 300. In terms of carrying methods, the adjustable crossbody shoulder strap can be connected to the chain 104, and with the side handle 105, it can meet different carrying needs and is flexible and convenient. The first storage compartment 200 can store a computer keyboard and mouse, while the keychain 201 and the first mesh pocket 203 facilitate the categorization and storage of items. The second storage compartment 300 is used to hold the computer, and the second mesh pocket 310 provides cushioning. The elastic band 320 and the telescopic brackets 330 located at the four corners control the computer's movement within the second storage compartment 300, achieving stable fixation. In the shock absorption module, the shock-absorbing pad 204 and the cushioning pad 340 work together to reduce the computer's movement in the direction perpendicular to the second storage compartment 300, and the first channel 101 and the second channel 107 further enhance the overall shock absorption performance. In addition, the groove 401 and the restraint strap 402 of the third storage module are located between the first storage compartment 200 and the second storage compartment 300, optimizing space utilization. Overall, this computer bag combines portability, partitioned storage, and high-efficiency shock absorption, providing comprehensive protection for the computer and related accessories.

[0030] In some embodiments of this application, the grip 105 is provided with an anti-slip pad 106, which is fixedly connected to the grip 105.

[0031] It should be noted that the anti-slip pad 106 is located near the center of the grip 105. The anti-slip pad 106 has small raised dots to increase friction. The anti-slip pad 106 is fixedly connected to the grip 105, and its position matches the natural gripping area of ​​the human hand. This effectively enhances the friction between the hand and the grip 105, significantly reducing the risk of the grip 105 slipping from the hand, even in situations such as sweaty hands, a heavy bag, or a slippery external environment, thus improving stability and safety during carrying. The structure of the small raised dots further increases the roughness of the contact surface. Without increasing the overall hardness of the grip 105, it enhances the fit during grip through physical friction, reducing hand fatigue and making carrying the laptop bag more comfortable and effortless. This is especially suitable for scenarios involving long-term carrying or frequent adjustments to carrying posture, reflecting the product's optimized user experience and human-centered design.

[0032] In some embodiments of this application, the shock-absorbing pad 204 has a hollow internal structure, and each shock-absorbing pad 204 is located at the three vertices of an equilateral triangle. The shock-absorbing pad 204 is located on the inner wall of the first storage chamber 200 and on the left side of the first storage chamber 200.

[0033] It should be noted that two shock-absorbing pads 204 are located on the left side of the first storage chamber 200, and one is located inside the first storage chamber 200. These three shock-absorbing pads 204 form a triangular shock-absorbing structure as the three vertices of an equilateral triangle. The shock-absorbing pads 204 are made of hollow rubber material and are fixed to the inner wall of the bag body 100 in an equilateral triangle vertex layout, providing multiple optimized shock-absorbing protection effects. The combination of the hollow structure and the elasticity of the rubber forms a composite buffer system. When the computer is under pressure, the compression of the internal air and the elastic deformation of the rubber work synchronously, which can effectively absorb and disperse the impact force from the vertical direction and multiple angles, significantly reducing the intensity of vibration transmitted to the computer. The vertex distribution of the equilateral triangle makes the three shock-absorbing pads 204 form a stable mechanical support structure, evenly covering the key stress areas of the inner wall of the bag, ensuring that vibrations from different directions can be attenuated by the synergistic buffering of at least two shock-absorbing pads 204, avoiding protection failure caused by local stress concentration. In addition, the high elasticity and wear resistance of the rubber material, combined with the integrated bottom connection design, not only ensures the structural stability of the 204 shockproof pad for long-term use, but also further enhances the cushioning performance through the material properties, providing 360-degree three-dimensional shockproof protection for the computer. It is especially suitable for reducing equipment damage in bumpy environments or accidental collision scenarios, reflecting the deep integration of structural design and material properties and comprehensive consideration for equipment safety.

[0034] In some embodiments of this application, the area between the second mesh bag 310 and the buffer pad 340 is a second storage chamber 300, and the elastic band 320 is disposed in the second storage chamber 300.

[0035] It should be noted that the second mesh bag 310, elastic band 320, telescopic bracket 330, and removable buffer pad 340 form a progressive protection system from the outside in: the second mesh bag 310 provides initial wrapping and cushioning; the elastic band 320 and the telescopic brackets 330 located at the four corners together form a planar limiting structure; through the combined effect of the elastic band 320 tightening and the telescopic brackets 330 locking, the lateral and longitudinal sliding of the computer within the bag is effectively suppressed; the removable buffer pad 340 forms a shock-absorbing buffer zone in the direction perpendicular to the second storage compartment 300, absorbing external impact forces. This layered design utilizes the flexible restraint of the elastic band 320 and the rigid locking of the telescopic bracket 330 to achieve stable fixation, while the removable buffer pad 340 ensures compatibility with different devices. Combined with the cushioning characteristics of the second mesh bag 310, it constructs a multi-angle, multi-dimensional shockproof protection system, ensuring that the computer is protected from vibration and collision damage during transport, while meeting users' dual needs for storage structure flexibility and practicality.

[0036] In some embodiments of this application, the telescopic bracket 330 includes: a telescopic rod 333 and a semi-circular claw 331. One end of the telescopic rod 333 is connected to the semi-circular claw 331, and the other end of the telescopic rod 333 is connected to the inner wall of the bag body 100. The telescopic bracket 330 is connected end to end by a plurality of telescopic rods 333 to achieve the telescopic function.

[0037] It should be noted that the telescopic bracket 330 adopts a nested connection design of telescopic rod 333 and semi-circular claw 331. The length is adaptively adjusted through the nested telescopic rod 333, and the arc-shaped locking structure of the semi-circular claw 331 forms a dynamic limiting and protection system for the computer. The telescopic feature of the telescopic rod 333 allows it to flexibly adjust the bracket span according to the size of the computer, ensuring that devices of different specifications can be stably fixed to the second storage compartment 300 by the claw, significantly improving structural adaptability. The arc-shaped design of the semi-circular claw 331 conforms to the edge contour of the computer, providing rigid limiting while avoiding damage to the device caused by sharp corner contact, combining fixing strength and protective flexibility. The nested telescopic rod 333 structure absorbs vibration energy through the frictional damping of multiple sleeves when under force, and with the flexible restraint of the elastic band 320, it suppresses computer shaking from the dual dimensions of "rigid locking and elastic buffering" in the planar direction. Especially when the bag is subjected to external impact or tilting, the device can be kept stable by the telescopic adjustment of the bracket and the curved surface fit of the claw, achieving universal protection and precise fixation for computers of different sizes.

[0038] In some embodiments of this application, a spring 332 is provided inside the telescopic rod 333. One end of the spring 332 is connected to the semi-circular claw 331, and the other end of the spring 332 is connected to the inner wall of the bag body 100.

[0039] It should be noted that the design of the spring 332 inside the telescopic rod 333 constructs a dual protection mechanism of dynamic buffering and adaptive fixation through the principle of elasticity. The two ends of the spring 332 are connected to the semi-circular claws 331 and the inner wall of the bag body 100, respectively. When the computer is inserted, the elastic tension of the spring 332 ensures that the claws maintain a flexible clamping force on the edge of the device. This not only adapts to computers of different thicknesses through deformation, avoiding damage to the outer shell caused by rigid compression, but also absorbs the vibration energy in the planar direction when the bag shakes or is impacted, reducing the hard collision between the computer and the inner wall of the bag. The elastic restoring force of the spring 332 and the nested telescopic structure of the telescopic rod 333 work together to give the telescopic bracket 330 both "rigid support" and "elastic buffering" characteristics during the limiting process. Especially when there are slight differences in the size of the device, the fine adjustment of the spring 332 maintains stable clamping. At the same time, in the case of severe vibration, the damping effect of the spring 332 attenuates the impact force. Together with the shock-absorbing components such as the anti-vibration pad 204 and the buffer pad 340, a multi-dimensional three-dimensional protection system is constructed to effectively improve the safety and fixed reliability of the computer in complex carrying environments.

[0040] In some embodiments of this application, the upper surface of the buffer pad 340 is provided with protrusions 341, which are evenly distributed on the upper surface of the buffer pad 340. The protrusions 341 are hollow structures, and the lower surface of the buffer pad 340 is a plane.

[0041] It should be noted that the evenly distributed hollow protrusions 341 on the upper surface of the cushioning pad 340, combined with the flat design of the lower surface, achieve a dual optimization of function and structure. The flat lower surface can be used directly as a mouse pad, allowing the laptop bag to function as a temporary office accessory while being carried. This meets the user's need for immediate mouse use in outdoor or mobile scenarios, avoiding the inconvenience of carrying an extra mouse pad and improving product practicality. The hollow protrusions 341 on the upper surface achieve efficient pressure reduction and cushioning through a combination of structural design and material properties. The hollow space inside the protrusions 341 forms an air cushion layer when compressed. Combined with the elastic deformation of the cushioning pad 340's rubber material, this effectively disperses and absorbs impact forces from the vertical direction, reducing the hard contact between the bottom of the laptop and the inner wall of the bag. Especially during bumps or collisions, the elastic compression of the protrusions 341 alleviates the pressure on the device, protecting the computer hardware. The evenly distributed layout of the protrusions 341 ensures uniform pressure transmission, avoiding localized stress concentration. At the same time, the hollow structure, while reducing the weight of the cushioning pad 340 itself, enhances shock absorption performance through aerodynamic principles, achieving a balance between functionality and portability.

[0042] In some embodiments of this application, the cross-sections of the first channel 101 and the second channel 107 are both circular, the first channel 101 and the second channel 107 are both semi-circular protrusions on the outer and inner sides of the package body 100, and the first channel 101 and the second channel 107 are both hollow structures.

[0043] It should be noted that the hollow channel with a circular cross-section has excellent resistance to compression. Its arc structure can evenly disperse external impact force, avoiding damage to the package or internal equipment caused by stress concentration at sharp corners. At the same time, when subjected to external force, the hollow cavity absorbs vibration energy through the synergistic effect of air buffering and material deformation, making it particularly suitable for protecting precision electronic equipment inside the package. The semi-circular protrusions on the inner and outer sides not only enhance the structural rigidity of the channel itself, but also form a three-dimensional protective layer of "outer convex buffering - hollow energy absorption - inner convex support".

[0044] In some embodiments of this application, the groove 401 is semi-circular, and the restraint strap 402 is connected to the bag body 100.

[0045] It should be noted that the arc-shaped contour of the semi-circular groove 401 and the flexible material of the strap 402 form a geometric fit. Under normal conditions, the strap 402 naturally fits the top of the groove 401, avoiding unnecessary structural space occupation and maintaining the neatness of the bag's interior layout. When it is necessary to secure items, the strap 402 can be stretched to detach from the top of the groove 401. The guiding effect of the arc-shaped groove 401 allows the strap 402 to wrap around or span the outside of the item, forming a stable elastic restraint structure. The tension of the strap 402 can be adjusted according to the size of the stored items. The arc of the semi-circular groove 401 evenly distributes pressure, avoiding surface wear or localized stress concentration caused by rigid restraint. At the same time, the concealed guiding function of the groove 401 enhances ease of operation. In addition, the design of the relaxed binding strap 402 and the groove 401 fits together and is hidden inside the bag structure when not in use, reducing the risk of external scratches. It takes into account both aesthetics and practicality, and allows the bag to maintain a compact structure when empty or loaded with items of different volumes, effectively improving space utilization efficiency and the flexibility of item fixation.

[0046] The working process of this utility model is as follows: The user can carry the computer bag through the handle 105 with anti-slip pads 106 on the side of the bag body 100 or the adjustable crossbody shoulder strap connected to the chain 104. After opening the first zipper 102 or the second zipper 103, the user can store accessories such as keyboards and mice in the first storage compartment 200 and fix small items with key buckles 201. The user can then put the computer into the second mesh bag 310 in the second storage compartment 300. The elastic band 320 covers the top of the computer and its edges are inserted into the telescopic bracket 330 of the semi-circular claws 331 to achieve flexible clamping and planar positioning. A removable cushioning pad 340 is placed between the computer and the inner wall of the bag body 100. The upper surface of the cushioning pad 340 has hollow protrusions 341. The lower surface can be used as a mouse pad. When the bag is impacted or vibrated, the hollow rubber shock-absorbing pads 204 and 340 of the first and second storage chambers 300, which are arranged in an equilateral triangle, and the hollow protrusions 341 on the upper surface of the buffer pad 340 reduce vertical vibration through air compression, material elastic deformation and pressure dispersion. The telescopic bracket 330 suppresses planar shaking. The hollow channels with circular cross sections on the upper and lower parts of the bag body 100 are combined to enhance the overall shock absorption. When in use, the telescopic bracket 330 can be adjusted according to the size of the computer. The buffer pad 340 can be temporarily removed and its lower surface can be used as a mouse pad. A pen or other cylindrical object can be placed inside the groove 401. Then, the first zipper 102 or the second zipper 103 can be closed.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
