Description

Intelligent door lock

Technical Field

The utility model relates to the technical field of electronics, in particular to an intelligent door lock.

Background

With the progress of science and technology and society, intelligent door locks are gradually popularized to thousands of households instead of traditional purely mechanical door locks. The current intelligent door lock comprises key switches for unlocking, locking, resetting and the like. However, these key switches are usually mechanical keys implemented by electronic component switches, and metal spring plates are adopted inside the key switches, so that the metal spring plates can be fatigued and lose elasticity after long-term use. In addition, extreme weather with high air humidity can also lead to corrosion of the metal spring. Once the metal spring sheet cannot rebound or cannot be pressed down, the function of the intelligent door lock is lost, and misoperation of the intelligent door lock can be caused under serious conditions.

In view of one or more problems of the existing intelligent door lock, the intelligent door lock according to the embodiment of the utility model is provided, wherein the touch pad is adopted to replace a mechanical key to realize unlocking, locking, resetting and other operations of the intelligent door lock.

Fig. 1 shows a schematic block diagram of an intelligent door lock according to an embodiment of the utility model. As shown in fig. 1, the smart door lock 100 according to an embodiment of the present utility model includes a touch pad 102 and a smart door lock control board 104 communicatively connected to each other, wherein: the touch pad 102 is configured to detect a touch of a finger to one or more touch pad detection areas on the touch pad, identify a sliding direction of the finger on the touch pad, and send a control signal to the smart door lock control panel in response to the detected touch and the identified sliding direction; the smart door lock control board 104 is configured to implement a control operation for the smart door lock in response to a control signal from the touch pad.

As shown in fig. 1, in some embodiments, the touch pad 102 may be configured to send control signals to the smart door lock control board 104 based on general purpose input Output communications (General Purpose Input/Output, GPIO). However, in some embodiments, the touch pad 102 may also be configured to interact with the smart door lock control board 104 based on universal asynchronous receiver/Transmitter (UART) communications or Inter-integrated circuit (Inter-Integrated Circuit, IIC) communications.

As shown in fig. 1, in some embodiments, the control signal sent by the touch pad 102 to the smart door lock control board 104 may be one of an unlock control signal, a lock control signal, a reset control signal, and a doorbell control signal, and the control operation of the smart door lock control board 104 for the smart door lock may be a respective one of an unlock operation, a lock operation, a reset operation, and a doorbell operation. For example, when the touch panel 102 transmits an unlocking control signal open_io to the intelligent door lock control board 104, the intelligent door lock control board 104 may implement an unlocking operation for the intelligent door lock; when the touch panel 102 transmits a closing control signal close_io to the intelligent door lock control board 104, the intelligent door lock control board 104 can implement a closing operation for the intelligent door lock; and when the touch pad 102 transmits the reset control signal reset_io to the smart door lock control board 104, the smart door lock control board 104 may implement a reset operation for the smart door lock.

Fig. 2 shows a front view of the touch pad shown in fig. 1. As shown in fig. 2, in some embodiments, the touch pad 102 may include at least three touch detection areas (e.g., five touch detection areas B1-B5), and each touch detection area may include a touch pad and a Light Emitting Diode (LED). In this case, the touch panel 102 may also be configured to control, for any one touch detection area, the LEDs in that touch detection area to be turned on and then to be turned off with a delay when a finger is detected to touch the touch pad in that touch detection area.

Fig. 3 shows a back view of the touch pad shown in fig. 1. As shown in fig. 3, in some embodiments, the power and control signal output terminals of the touch pad 102 may be located on the back side of the touch pad 102. For example, the power and control signal output terminals of the touch pad 102 may be located on the back side of the touch pad 102 near the control signal input terminals of the smart door lock control board 104.

An example implementation of the door opening operation procedure, the door closing operation procedure, and the reset operation procedure for the smart door lock in the case where the touch panel 102 shown in fig. 1 includes five touch detection areas B1 to B5 of the layout shown in fig. 2 is described below with reference to fig. 4 to 6. Here, it is assumed that the power supply voltage of the touch panel 102 is 3.3V, and the initial states of the unlock control signal open_io, the close control signal close_io, and the reset control signal reset_ip are all high levels after the touch panel 102 is powered.

Fig. 4 shows an example flowchart of a door opening operation procedure for an intelligent door lock according to an embodiment of the present utility model. As shown in fig. 4, when the touch panel 102 detects that a finger starts touching from the touch pad of the third touch detection area B3, recognizes that the finger touches the touch pads of the third, fourth, and fifth touch detection areas B3, B4, B5 in this order from left to right, and changes the unlock control signal open_io from high level to low level and maintains the low level for 2s and then resumes the high level each time the time interval for switching the touch pads does not exceed 500 ms. After the intelligent door lock control board 104 recognizes that the unlock control signal open_io has generated a low level for 2s and restored a high level, it determines that a door opening event has been generated to thereby perform an unlocking operation for the intelligent door lock.

Fig. 5 shows an example flowchart of a door closing operation procedure for an intelligent door lock according to an embodiment of the present utility model. As shown in fig. 5, when the touch pad of the finger from the third touch detection area B3 is detected to start touching, the touch pad of the finger is recognized to be sequentially touched in the third, second, and first touch detection areas B3, B2, B1 in order from right to left, and each time the time interval for switching the touch pad is not more than 500ms, the lock control signal close_io is changed from the high level to the low level and maintained at the low level for 2s, and then the high level is restored. After the smart door lock control board 104 recognizes that the closing control signal close_io generates a low level for 2s and restores a high level, it determines that a closing event is generated to implement a closing operation for the smart door lock.

Fig. 6 shows an example flowchart of a reset operation procedure for an intelligent door lock according to an embodiment of the present utility model. As shown in fig. 6, the touch pad 102 returns the reset control signal reset_io from the high level to the low level and remains at the low level for 2s after detecting the touch pad of the same length of time for the first and fifth touch detection areas B1 and B5 for 3 s. After recognizing that the reset control signal reset_io generates a low level for 2s and restores a high level, the smart door lock control board 104 determines that a reset event is generated to implement a reset operation for the smart door lock.

It should be appreciated that operations implemented by using a touch pad instead of a mechanical key include, but are not limited to, an unlocking operation, a locking operation, a resetting operation, a doorbell operation, etc., a finger touching the touch pad in each touch detection area may take the form of a single click, a double click, a long press, a sliding, etc., and an LED in each touch detection area may implement a light effect of a breathing light, a ticker, a running light, etc.

The present utility model may be embodied in other specific forms without departing from its spirit or essential characteristics. The present embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
