Anti-collision intelligent padlock

Abstract

The invention relates to an anti-collision intelligent padlock. As a torsional spring is arranged in an unlocking wheel with an eccentric boss and a prestress is generated by the torsional spring dueto a relative rotating space at a certain angle between the unlocking wheel and a motor shaft of a motor, when a user needs to unlock the padlock, the user can unlock the padlock smoothly whether theuser drives a locking mechanism to a locking position by way of mobile phone NFC or Bluetooth and the like first and presses a lock ring to lock the padlock or presses the low ring and drive the locking mechanism to the locking position to lock the padlock without pressing the lock ring by one hand and loosening the lock ring when the driving mechanism arrives at the locking position, so that thedifferent using habits of people are met and the using experience of people are further improved greatly. In addition, in the locking state, the eccentric boss of the unlocking wheel further moves toa blocking position of an anti-collision area under the action of stress of the torsional spring to prevent he undesirable to collide the padlock to unlock the padlock, so that the anti-collision intelligent padlock is more reasonable in structure, higher in antitheft performance and good in using experience effect and further meets using habits of people.

Description

technical field [0001] The invention relates to an intelligent padlock. Background technique [0002] At present, most smart padlocks are mainly divided into three categories, one is a smart padlock with a built-in battery; the other is a padlock without a battery inside and powered by an electronic key; the other is a smart padlock without a battery inside and powered by a dedicated wireless key . [0003] At present, most of the waterproof padlocks that can be locked directly and quickly without the need for an electronic key mostly use a single bolt mechanism for the unlocking part. It is suitable for waterproof use, and the technology is very mature; however, the anti-collision protection of this structure uses the principle of spring force to overcome the inertia of the lock tongue during impact.

Problems solved by technology

[0003] At present, most of the waterproof padlocks that can be locked directly and quickly without the need for an electronic key mostly use a single bolt mechanism for the unlocking part. It is suitable for waterproof use, and the technology is very mature; however, the anti-collision protection of this structure uses the principle of spring force to overcome the inertia of the lock tongue during impact. To effectively prevent the impact, the spring force of the lock tongue must be large; On smart padlocks, motors or electromagnets are used to control the movement of the deadbolt. Due to the limited power of the motor or electromagnet, if the spring force is too large, it will cause jamming, resulting in failure to unlock normally; and if the spring force is too small, it will cause Safety hazards that can be unlocked by impact

In order to solve the risk that the single tongue lock is easy to be knocked open, recently, a structure that must be authorized and pressed for a long time to lock the lock ring has appeared on the market until the lock is completed, and the lock tongue is supported by the locking mechanism, so as to prevent being locked. Knock open, but this method is not suitable for people's usage habits, and there are locking limitations when using it, especially the application experience on passive NFC locks is even worse

[0004] In addition, most of the current smart padlocks are unreasonably sealed, and it is difficult to achieve the IP67 protection level, and it is easy to cause water damage when unlocked in the case of rainwater
