Description

TECHNICAL FIELD

The present application relates to the technical field of protective arrangement, and more particularly to a protective arrangement for a laptop and a bag.

BACKGROUND

At present, some of bags sold in the market currently are added with an inner pocket for accommodating a laptop. However, most of these designs are still presented in the form of textiles. Although space isolation can be achieved and shaking is avoided, while the protection for the laptop resistant to collision and fall down is not enough. In addition, some of bags are not provided with a sandwich or inner pocket to hold the laptop. And with the increasing number of laptops, when a user places an unprotected laptop in this type of bag, it is easy to damage the laptop in the event of violent shaking, collision, fall down and other accidents.
To solve the above problem, in the prior art, the common methods includes:
Thickening of the bottom of the bag: the protection function is achieved by changing the thickness of the material and adding fillers, but the thickness of the fillers is limited and the material selection is limited.
Suspending the inner pocket: the bottom of the inner pocket does not directly touch the bottom of the bag and has a certain degree of buffering effect.
Thickening the package of the inner pocket: increasing thickness to the inner pocket by adding fillers; the most likely cause of damage to the laptop when it is placed inside the bag is that the backpack is falling down, the two right-angle positions and side position of the laptop closed to the bottom of the bag is suffered from violent impact, and resulting in laptop damage.
By adding fillers at the bottom of the backpack, increasing the thickness of the bottom material, suspending the inner pocket, and thickening the package of the inner pocket, which has a certain amount of mitigation, but it is very limited, especially the bag is filled with less items, the drop height is high, the falling down speed is faster and the impacted object is harder, the laptop cannot be protected effectively.
In addition, the publication CN204433393U discloses a laptop packaging cushioning structure; which further discloses that the laptop packaging cushioning structure includes a box body (1), the box body (1) is a hollow rectangular interior cavity, and each of a bottom and top inner hollow rectangular cavity is respectively provided with an M type lining for supporting the laptop received in the package.
