Embodiment 1

[0090] Such as figure 1 As shown, the smart lock circuit of the present invention includes an NFC communication module 1 , a rectifying circuit 2 , a voltage stabilizing circuit 3 , an energy management circuit 4 , an energy storage module 5 , a driving module 6 and a control module 7 .

[0091] The NFC communication module 1 includes an NFC antenna 11, and the NFC antenna 11 is used for collecting radio frequency energy in a received NFC signal.

[0092] Wherein, the NFC antenna 11 can collect more than 20 mW of electric energy in the NFC signal transmitted by the smart terminal with the NFC antenna.

[0093] The NFC antenna 11 is set inside, on the inner surface or on the outer surface of the smart lock shell, and it needs to be set as close to the outer surface of the smart lock as possible, and is composed of a multi-turn coil with an area of ​​900mm 2 -2500mm 2 Inside.

[0094] The NFC communication module 1 also includes a data interface 12 ; the data interface 12 is ...

Embodiment 2

[0127] Such as figure 2 As shown, the difference between this embodiment and embodiment 1 is:

[0128] The NFC antenna 11 of the present embodiment includes an independent energy antenna 111, an independent receiving antenna 13, and an independent transmitting antenna 14; the NFC communication module also includes a demodulation module 15, a modulation module 16, and an NFC controller 17. The receiving antenna 13 is electrically connected to the demodulation module 15, the transmitting antenna 14 is electrically connected to the modulation module 16, and the NFC controller 17 is electrically connected to the demodulation module 15 and the modulation module 16 respectively . The NFC communication module 1 may also include an NFC antenna interface. Wherein, the energy antenna 111 is used to collect electric energy in the received NFC signal.

[0129] The receiving antenna 13 is used to receive the NFC signal transmitted by the NFC card reader, and the demodulation module 15 ...

Embodiment 3

[0136] Such as image 3 As shown, the difference between this embodiment and embodiment 2 is:

[0137] The NFC antenna 11 of this embodiment includes an independent energy antenna 111 and an independent communication antenna 20, that is, an independent communication antenna 20 is used to replace the independent receiving antenna 13 and the independent transmitting antenna 14 in Embodiment 2, so as to realize the NFC signal receiving and sending.

[0138] Specifically, the communication antenna 20 is electrically connected to the demodulation module 15 and the modulation module 16 . After the communication antenna 20 receives the NFC signal transmitted by the NFC card reader, the demodulation module 15 demodulates and transmits the demodulated data to the NFC controller 17;

[0139] The NFC controller 17 transmits data to the modulating module 16 according to a predetermined format, and the modulating module 16 modulates and sends an NFC signal to the NFC card reader through ...

Abstract

The invention discloses a smart lock circuit and a smart lock. The smart lock circuit comprises an NFC communication module and a drive module. The NFC communication module electrically connected to the drive module includes an NFC antenna that is configured to collect power in a received NFC signal; and the NFC communication module is used for transmitting the power collected by the NFC antenna to the drive module. The drive module is used for driving a smart lock to perform locking or delocking by using the power. Therefore, a defect that the existing smart lock needs to use an external power for power supply is overcome; the battery limitation is eliminated; and the smart lock is used conveniently. Meanwhile, since no battery is needed and not battery charging circuit needs to set, thesize of the smart lock is reduced and the weight is reduced, so that the production cost of the smart lock is lowered.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an intelligent lock circuit and an intelligent lock. Background technique [0002] As a smart home product that has emerged in recent years, smart locks have the characteristics of easy use, high security, and powerful functions. Most of the existing smart locks are powered by batteries, and then communicate with the user's mobile phone through Bluetooth or NFC (Near Field Communication, near field communication) to verify the user's identity and perform the locking and unlocking operations of the smart lock. [0003] However, the existing smart locks are only suitable for door locks due to issues such as volume or power consumption. When applied to occasions other than door locks, for example, small personal cabinet locks, suitcase locks and shared bicycle locks, many difficulties will be encountered. Due to the small size of this type of smart lock itself, it i...
