Technical Field
[0001] The utility model relates to a backpack, in particular to a hard-shell anti-theft backpack. Background Art
[0002] The difference between a hard-shell backpack and an ordinary backpack is that a hard protective layer is provided inside the hard-shell backpack, mainly used to protect the items in the backpack from physical damage. Usually, whether it is a hard-shell backpack or an ordinary backpack, it is closed by components such as zippers or buckles. However, this also means that lawbreakers can relatively easily take away the backpack and open it to take the items inside. To improve security, some anti-theft backpacks with password locks have emerged on the market. Although this design increases security, there are still the following deficiencies:
[0003] 1. The password locks of existing anti-theft backpacks mainly rely on passive protection mechanisms, that is, they can only be unlocked when the correct password is entered, but no active measures are taken to prevent illegal unlocking behavior;
[0004] 2. If the backpack is placed unattended for a long time, the password lock without an alarm mechanism cannot immediately notify the user or people around in case of unauthorized access, which gives thieves more time to try to unlock it;
[0005] 2. Since most password locks use simple number combinations and do not have additional security measures, the passwords are more easily cracked by brute force.
[0006] Based on this, to solve the above-mentioned technical defects, a hard-shell anti-theft backpack is proposed. Content of the Utility Model
[0007] In order to overcome the disadvantages that existing anti-theft backpacks do not have an alarm function and have low security, the technical problem of the utility model is: to provide a hard-shell anti-theft backpack.
