Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides an intelligent door lock power supply system based on contact power supply, including:

the intelligent door lock comprises a power adapter 5, an interlocking sheet contact arranged on a door lock interlocking sheet 4, a guide sheet contact arranged on a door lock guide sheet 6, a storage battery, a control unit and an intelligent door lock power supply circuit; wherein the interlock tab contact comprises: interlocking piece positive pole contact 7 and interlocking piece negative pole contact 8, the guide vane contact includes: a guide sheet positive contact 10 and a guide sheet negative contact 9;

the power adapter 5 is connected with the interlocking sheet contact, and the power adapter 5 is connected with mains supply; the guide sheet contact is respectively connected with the storage battery and the intelligent door lock power supply circuit; the control unit is connected with the intelligent door lock power supply circuit;

the door lock guide plate 6 is arranged on the side face 2 of the door body 1, the door lock interlocking plate 4 is arranged on the door frame 3, the guide plate positive contact 10 is connected with the interlocking plate positive contact 7 when the door is closed, and the guide plate negative contact 9 is in contact with the interlocking plate negative contact 8.

The working principle of the system is as follows:

when the door is in the open mode, the interlocking piece contact on the mutual locking piece 4 of lock separates with the guide piece contact on the lock guide piece 6, can't change the commercial power then supply power to intelligent lock through power adapter 5 this moment, and then the control unit control battery supplies power to intelligent lock through intelligent lock supply circuit this moment. When the door is in a closed state, the interlocking sheet contact on the door lock interlocking sheet 4 and the guide sheet contact on the door lock guide sheet 6 are in contact with each other, the circuit is switched on, and at the moment, the control unit controls the direct current of the power adapter 5 after conversion to supply power to the intelligent door lock through the intelligent door lock power supply circuit, and meanwhile, the storage battery is charged.

In a preferred embodiment, in the door lock interlocking piece 4, the rest parts except the interlocking piece contact are covered with an insulating glue layer; in the door lock guide sheet 6, the rest parts except the guide sheet contact are covered with insulating rubber sleeve layers. Because the mutual locking plate 4 of lock and lock guide plate 6 are the easy wire of metal product generally, consequently through setting up insulating glue layer, can prevent to electrocute, guarantee the security.

As shown in fig. 4, in a preferred embodiment, the intelligent door lock further includes a solar panel, and the solar panel is connected to the intelligent door lock power supply circuit and the storage battery. The solar panel is additionally arranged in the embodiment for supplying power, so that the solar energy power supply device can adapt to the situation that commercial power cannot be introduced, such as power failure in daily life. In this embodiment, when the door is in the open state, except that can supply power through the battery, can also supply power to intelligent lock through solar cell panel, charge the battery simultaneously. When the door is in the closed condition, if the power failure condition appears this moment, continue the power supply to intelligent lock through solar cell panel, further improve the continuation of power supply.

As shown in fig. 5, in a preferred embodiment, the system further comprises an illumination sensor connected with the control unit. Because the electric quantity of the solar cell panel is influenced by the illumination intensity, the illumination intensity is sensed by adding the illumination sensor, and then whether the solar cell panel is started to supply power is judged. The principle of operation of the system in this embodiment is as follows:

when the door is in an open state, the interlocking sheet contact on the door lock interlocking sheet 4 and the guide sheet contact on the door lock guide sheet 6 are separated from each other, at the moment, the mains supply cannot be converted through the power adapter 5 and then the intelligent door lock is powered, at the moment, the control unit receives an illumination intensity signal transmitted by the illumination sensor and judges whether the external illumination intensity reaches a preset threshold value or not according to the illumination intensity signal; if so, controlling the solar cell panel to supply power to the intelligent door lock and charge the storage battery; and if not, controlling the storage battery to supply power to the intelligent door lock.

When the door is in a closed state, the interlocking sheet contact on the door lock interlocking sheet 4 and the guide sheet contact on the door lock guide sheet 6 are in contact with each other, the circuit is switched on, and at the moment, the control unit controls the power adapter 5 to supply the converted direct current to the intelligent door lock through the intelligent door lock power supply circuit, and meanwhile, the storage battery is charged.

If the interlocking piece contact on the door lock interlocking piece 4 and the guide piece contact on the door lock guide piece 6 are in contact with each other but no current flows at this time, a power failure condition may occur. At the moment, receiving an illumination intensity signal transmitted by an illumination sensor, and judging whether the external illumination intensity reaches a preset threshold value according to the illumination intensity signal; if so, controlling the solar cell panel to supply power to the intelligent door lock and charge the storage battery; and if not, controlling the storage battery to supply power to the intelligent door lock. Thereby solve the power supply problem of intelligent lock under the power failure state.

On the basis of the system item embodiment, the invention correspondingly provides a method item embodiment.
