To sum up, the function and the characteristics of the intelligent Bluetooth padlock are specifically as follows: 1. intelligent state detection system: this bluetooth intelligence padlock is in under any state, detects its on-off state and feeds back to control center through the APP, lets the user clearly know the real-time operating condition of this bluetooth intelligence padlock. 2. The lock opening and closing independent control system comprises: the process of opening and closing the lock is controlled step by step through APP, which is different from the traditional padlock; when the APP sends an unlocking instruction, the electronic lock hook can be pulled open, and the lock cannot be closed after the lock hook is pulled open; when the APP sends a locking instruction, the electronic lock hook can be pressed to lock, and after the lock is locked, the lock hook cannot be pulled out. 3. Adopting a code scanning design: this bluetooth intelligence padlock realizes that one-dimensional code and two-dimensional code connect the function of unblanking. 4. Simple latch hook assembly system: the lock hook of the intelligent Bluetooth padlock is different from the traditional assembly mode, the traditional mode adopts pin fixation, and the intelligent Bluetooth padlock adopts a spring pin 'insertion type' one-time fixation mode; the lock hook, the marble and the marble spring are assembled into a component and directly inserted into the lock body to complete the positioning and rotating functions, thereby greatly improving the assembly efficiency and simplifying the part processing technology. 5. Automatic dormancy and awakening system: this bluetooth intelligence padlock is being in off-working state, and the system can intelligent judgement tool to lock state and make it get into dormant state to this reaches energy-conserving purpose, the power consumption that significantly reduces. When the lock is required to work, the awakening button is pressed, the lock supplies power, and the lock is recovered to be used. 6. In the first and second embodiments, the structure optimization design is performed: when the lock is closed, the cam rotates back to the original position, and the lock latch is driven to the lock closing position by the pin spring, so that the problems of incomplete lock closing, false lock and the like are solved. Meanwhile, the cam structure in the second embodiment is optimally designed: when the lock is unlocked, the cam drives the lock bolt to move, the cam inner cam pin is always in an ejecting state, and after the cam rotates clockwise by about 45 degrees, the cam pin enters the track groove in the lock bolt cam groove and is pressed into the cam along the track groove; when the lock is closed, the cam is rotated back to the original position, the latch is driven to the locking position by the latch spring, at the moment, the lock head of the latch is automatically inserted into the lock hole of the latch hook through the latch spring, the cam pin is automatically reset into the cam to complete the locking action, and when the latch forcibly moves towards the unlocking direction, the cam blocks the latch, so that the latch cannot be forcibly opened. 7. The circuit board mounting mode is optimally designed: the conventional circuit board mounting mode is the fix with screw, has the screw to beat the back and damage the circuit board phenomenon partially, and this bluetooth intelligence padlock is by shield and reference column cooperation fixed circuitry board. 8. Locking and locking hook positioning: the lock hook can rotate 360 degrees after unlocking in the design of a conventional padlock, a locking point needs to be manually found when the lock is closed, and the lock hook rotates to a limiting position to directly press down the lock when the lock is closed, so that the locking point does not need to be found. 9. The appearance uses streamlined design, makes the tool to lock look the lines more clear pleasing to the eye.

This bluetooth intelligence padlock is unstable to present padlock quality, assembles complicated scheduling problem, and the shock resistance that takes precautions against earthquakes is increased to the weight that significantly reduces under the condition that does not influence its intensity, effectively protects inside electron and mechanical structure's safety, is one kind and has state monitoring, sweeps the intelligent bluetooth tool to lock of sign indicating number and interface output, is the section and concentrates the bluetooth intelligence padlock of each item powerful as an organic whole. The existing intelligent padlock has the modes of mechanical unlocking, electric control unlocking, Bluetooth unlocking and the like, wherein the Bluetooth unlocking is realized by virtue of simplicity, the convenient unlocking mode is unique, and the Bluetooth intelligent padlock also adopts the signal working principle of Bluetooth unlocking.
