[ detailed description ] embodiments

The utility model relates to an intelligence padlock can be active, passive mode, adopts the motor to drive the unblock, as shown in fig. 1 to 4, including lock body 1, catch 2, establish spring bolt 3, catch spring 4, control circuit 5, spring bolt state inductor 6 and the motor 7 in lock body 1, their theory of operation is the same basically with the structure of present intelligence padlock, for this reason no longer detailed, the difference is: the end of the lock ring 2 close to the locking notch 21 is provided with a rainproof structure 9 which comprises a lock ring sealing sleeve 91, a rainproof cap 92 and a sealing ring 93, wherein the lock ring sealing sleeve 91 can be sleeved outside the lock ring 2 in a relatively movable manner, the lower end of the lock ring sealing sleeve 91 is fixed in the lock body 1 in a tight fit manner (usually, ultrasonic welding is needed), the upper end of the lock ring sealing sleeve is exposed out of the lock body 1, and the inner wall of the upper end of the lock ring sealing sleeve is provided with; the rain-proof cap 92 is a hollow tube, the upper end of the rain-proof cap is tightly sleeved on the lock ring 2 in a matching manner (usually, ultrasonic welding is needed), and the lower end of the rain-proof cap covers the exposed part of the seal sleeve 91 of the lock ring, so that rainwater falling on the lock ring above the rain-proof cap can flow downwards to the upper surface of the lock body along the outer wall of the rain-proof cap, and even if a small part of water vapor permeates into the rain-proof cap, the rainwater can be blocked by the seal ring 93 and cannot continuously permeate into the lock body downwards along the lock ring; and the rainwater that falls on the lock body upper surface because the lock ring seal cover 91 is higher than the lock body upper surface and install in the lock body with tight fit, so the rainwater of lock body upper surface can't cross the lock ring seal cover upper end and infiltrate in the lock body, just so can the significantly reduced rainwater along the work that the lock ring infiltrates electric elements such as influence control circuit 5, motor 7 and spring bolt state inductor 6 in the lock body to the waterproof performance of intelligent padlock has been improved greatly.

The unlocking of the intelligent padlock is realized by the pushing of a motor, the locking of the intelligent padlock can be reset and locked by a spring as in the prior art, however, the anti-knock mode of the structure adopts spring force to overcome the defect that the self-locking of the lock tongue is released after the inertia retraction of the lock tongue when the external force knocks, so the anti-knock function of the padlock is influenced by the elastic force of the spring at present, the spring force is usually made to be larger, but the intelligent padlock is unlocked by controlling the movement of the lock tongue by the motor or the electromagnet, and the force of the motor or the electromagnet is limited, so that the intelligent padlock can be jammed and cannot realize normal unlocking by the motor or the electromagnet if the spring force of the spring is set to be larger; if the spring force of the spring is too small, the potential safety hazard that the lock is easily knocked and unlocked by a lawbreaker is caused. For this purpose, the present embodiment is a passive intelligent padlock, which is a preferred embodiment, and an NFC antenna 8 is provided on the surface of the lock body 1; the motor 7 drives the lock tongue to horizontally slide through the eccentric motor shaft 71 or the cam to enter and exit the lock opening 21 of the lock ring 2; a dropping groove 31 for the eccentric motor shaft 71 or the cam to drop is provided on the latch tongue 3. In the present embodiment, an eccentric motor shaft is used, and thus, the eccentric motor shaft 71 of the motor 7 is inserted into the drop-in groove 31 of the latch bolt 3.

The embodiment is a passive intelligent padlock and is suitable for a mobile phone with an NFC function (an APP program specially used for unlocking is installed on the mobile phone) or a key. When the lock needs to be unlocked, the NFC of the mobile phone or the key is close to the NFC antenna position on the surface of the lock body, and when the NFC antenna 8 induces the electromagnetic wave of the NFC of the mobile phone or the key, the electromagnetic wave is converted into electric energy by the control circuit 5 and is supplied to the control circuit 5 to work; then, the mobile phone or the NFC key communicates with the control circuit 5 through the NFC antenna 8 of the lock body to determine whether unlocking is allowed, and when it is determined that the lock is allowed to be unlocked, the control circuit 5 controls the motor 7 to operate to push the lock tongue 3 away from the lock opening 21 of the lock ring 2 to the unlocking position, so that the lock tongue is unlocked, and then the lock ring 2 bounces upward under the action of the lock ring spring 4 to realize the unlocking process. When will shutting, press the catch 2, be close to the NFC antenna 8 position of lock body 1 through the NFC of cell-phone or key, NFC antenna 8 senses the NFC electromagnetic wave of cell-phone or key and converts the electric energy into through control circuit 5, in order to provide control circuit 5 work, NFC antenna and the control circuit communication of lock body are passed through to the NFC of cell-phone or key, and when judging this lock and allow shutting, control circuit 5 control motor 7 rotates the back and drives spring bolt 3 and insert in the fore shaft 21 of catch 2, make the catch unable bounce, just so accomplished the process of shutting. The connection relationship and the operation principle between the motor, the control circuit, the bolt state sensor 6 and the NFC antenna 8 are common in the passive intelligent padlock at the present stage, and are not described in detail here.

When the cam is adopted, the cam is arranged on a non-eccentric motor shaft of the motor, so that the motor can horizontally push and pull the bolt to unlock and lock.

From the above, since the motor 7 horizontally slides in and out of the locking notch 21 of the locking ring 2 by the eccentric motor shaft 71 or the cam to unlock and lock, the spring is omitted to reset the locking tongue for locking, so that the following advantages are provided: on one hand, the motor motion load of the intelligent lock is reduced, so that the service life of a product is prolonged, and the power consumption is reduced; on the other hand, the lock tongue can not be released by the outsider through the inertia retraction of the lock tongue caused by the external force knocking, so that the anti-theft performance can be greatly improved.

In this embodiment, a reinforcing sleeve 72 is sleeved on the eccentric motor shaft 71 of the motor 7 to reduce the wear of the motor shaft.

Preferably, a bolt position limiting pin 10 is arranged in the lock body 1, and is transversely dropped in a position limiting groove 32 of the bolt 3 for limiting the maximum horizontal sliding amplitude of the bolt so as not to influence unlocking and locking due to too large amplitude.
