Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is an intelligent lock that this application embodiment discloses, includes: a sensing unit 101, a controller 102 and a transmission mechanism 103.
The sensing unit 101 is in data connection with a controller 102, and the controller 102 is in data connection with a transmission mechanism 103. Specifically, the specific manner of data connection may include: connected by a data transmission medium such as a data line (i.e., a telecommunications connection), or connected by wireless. Wherein the sensing unit 101 may include at least one of a pressure sensing unit and a capacitive sensor. The pressure sensing unit is used for sensing external pressing. The capacitance sensor is used for sensing whether a human body touches or not. Specifically, the pressure sensing unit may be a pressure sensor or a press tact switch.
Generally, a pressure sensor includes a sensing electrode, a metal plate and a processing chip, and the principle of sensing external pressure by the pressure sensor is shown in fig. 2: a capacitance value is formed between a sensing electrode of the pressure sensor and the metal flat plate, a flat plate area is lightly pressed, a distance value between the sensing electrode and the metal flat plate, namely a d value, changes to cause capacitance value change, and a processing chip (not shown in figure 2) of the pressure sensor judges external pressing according to the acquired voltage value.
The principle of the capacitive sensor for sensing whether a human body touches or not is shown in fig. 3: the capacitance sensor and the ground form an induction capacitor with fixed charging and discharging time, and when a human body such as a finger approaches a touch pad of the capacitance sensor, a coupling capacitor is formed, so that the inherent charging and discharging time is changed. Whether a human body approaches the touch panel of the capacitance sensor can be detected by measuring the change of the charging and discharging time.
The transmission mechanism 103 has two states of openable and non-openable. In the openable state, the intelligent door lock can be opened from the inside of the door. In the non-openable state, the smart door lock cannot be opened from the inside of the door.
The controller 102 is configured to control the transmission mechanism 103 to be in an openable state according to a sensing signal of the sensing unit, and when the sensing signal is not received, the controller does not send a control instruction to the transmission mechanism 103, so that the transmission mechanism 103 is in an unopened state.
That is, the controller 102 is connected to the sensing unit 101, the sensing unit 101 sends a sensing signal to the controller 102 when sensing external pressing and/or human body contact, and the controller 102 controls the transmission mechanism 103 to be in an openable state according to the received sensing signal. In the openable state, the intelligent door lock can be opened from the inside of the door. Alternatively, to prevent the false determination, the controller 102 may control the transmission mechanism to be in the openable state when the sensing signal is greater than the preset threshold.
If the sensing unit 101 does not sense external pressing and/or human body contact, it will not send a sensing signal to the controller 102, and the transmission mechanism 103 will remain in the non-openable state.
It can be seen that, in the intelligent door lock shown in fig. 1, the sensing unit, the transmission structure and the controller are combined, and the transmission mechanism is controlled by the sensing signal to realize the unlocking in the door, so that when a human body presses the sensing unit and/or contacts the sensing unit, the intelligent door lock can be unlocked from the door, otherwise, the intelligent door lock is in a state that the intelligent door lock cannot be unlocked from the door. Compared with the prior art of preventing the cat eye from unblanking, unless sensing human body and pressing and/or contact, the lock is always in the indoor can not open the state, so, can effectually prevent to unblank through the cat eye to, combine together electronic induction control and mechanical structure, the mode of preventing the cat eye from unblanking is realized depending on mechanical structure with current alone and is compared, and electronic induction control has higher security and convenience. For example, a simple mechanical structure is more likely to be opened by a modified special tool entering through the cat-eye mounting hole, but the electronic sensing element increases the difficulty for a lawbreaker to operate through the cat-eye mounting hole. It should be noted that, even if the sensing unit includes only the pressure sensing unit, the pressure sensing unit as the electronic device has a smaller area than a purely mechanical structure, and therefore, the difficulty of pressing by a lawbreaker through the cat eye mounting hole is increased.
Further, the user can not carry out any operation wantonly, and the lock is in can not the open state all the time promptly, and when the user need open the door, with the induction element produce the contact can, consequently, the user need not to trigger intentionally and prevents cat eye technique of unblanking, can obtain better use and experience.
The specific structure of the transmission mechanism 103 is shown in fig. 4, and includes: a door inner handle 1031, a handle diverter 1032, a steering limit plate 1033, and a motor 1034.
The door inner handle 1031 is connected to the handle reversing member 1032 (specifically, as shown in fig. 4, the mechanical connection is possible, and the specific connection structure can be referred to in the prior art). The steering limit plate 1033 is connected to the motor 1034 (for example, by a mechanical structure, and a specific connection structure can be referred to in the prior art). The motor 1034 can control the displacement of the steering limiting plate 1033, so that the rotation of the handle reversing element 1032 is not hindered when the steering limiting plate 1033 is at the first position, and the rotation of the handle reversing element 1032 is hindered when the steering limiting plate 1033 is at the second position.
Specifically, as shown in fig. 4, a stopper is disposed on the handle bar 1032, the second position, that is, the steering limiting plate 1033, extends out of the handle bar 1032, and further, the steering limiting plate 1033 is clamped into a position in a clamping groove of the handle bar 1032, in this case, an occupation of the steering limiting plate 1033 partially coincides with a moving track of the stopper, so that the steering limiting plate 1033 blocks the movement of the stopper, and the handle bar 1032 cannot be rotated. The first position is a position where the steering stopper plate 1033 is located away from the catching groove of the handle reverser 1032.
In particular, in connection with the transmission illustrated in fig. 4, the controller 102 is in data communication with the motor 1034. For example, when the controller 102 receives the sensing signal, it sends an electrical signal to the motor 1034, and the motor 1034 drives the steering limiting plate 1033 to displace accordingly.
Based on the transmission mechanism shown in fig. 4, specifically, the pressure sensor may be provided on the door inner handle 1031. The capacitive sensor may also be disposed on the door inner handle 1031, and specifically, the pressure sensor is disposed on a first region of the door inner handle 1031, and the capacitive sensor is disposed on a second region of the door inner handle 1031. Because the door inner handle is usually made of metal, in order to make the door lock have better hand feeling, the pressure sensor arranged on the door inner handle can be a metal pressure sensor. The requirements of the corresponding hardware structure technical parameters of the metal pressure sensor are as follows:
the material may be: zinc alloy, aluminum or stainless steel.
The distance d2 between the touch pad touch and the sensor pad is 0.1mm-0.2 mm.
The thickness H of the metal touch panel touch is 0.4 mm-0.5 mm.
The diameter D of the induction plate is: d >12 mm.
The area size L of the metal touch panel is L ═ D +2mm
The shape of the Sensor pad may be: circular, oval or square.
It should be noted that the above parameters are examples. Because the pressure sensor has high requirements on static electricity resistance and severe environments such as electromagnetic pulse interference resistance, temperature and humidity, vibration and the like, in practical application, different product strategy strategies are different in order to prevent false triggering, and parameters used in practice can be set according to experience.
Alternatively, a capacitive sensor or a pressure sensor may be provided in other regions than the door inner handle 1031.
Optionally, the pressure sensing unit and the capacitive sensor may be set to different areas according to user experience and product definition. For example, the pressure sensing unit is disposed on the door inner handle, and the capacitive sensor is disposed in a region other than the door inner handle, and it is also possible that the capacitive sensor is disposed on the door inner handle, and the pressure sensing unit is disposed in a region other than the door inner handle. The other area may be an area of the smart door lock other than the inner handle of the door, such as a control panel, or an area of the smart door lock such as a door body.
Alternatively, in the above embodiments, the capacitive sensor may be a multi-region capacitive sensor. A multi-region capacitive sensor is a capacitive sensor in which the touch pad is distributed over a plurality of regions. Whether the multi-region capacitive sensor can judge that the user generates contact from a plurality of regions, and the judgment result is more accurate, so that the safety of the intelligent door lock can be further improved.
Based on the transmission shown in fig. 4, in particular, the controller 102 and the motor 1034 may be disposed in the rear panel of the smart door lock. The sensing unit 101 and the controller 102 communicate with each other via a bus. When the sensing unit 101 senses the signal, it sends a command to the controller 102, and the controller 102 controls the motor 1034 to drive the steering limiting plate 1033 to move from the first position to the second position.
It should be noted that, in order to further improve the safety, the controller 102 controls the motor 1034 to drive the steering limit plate 1033 to move to the second position after the period of time that the steering limit plate 1033 is in the first position is longer than the preset period of time. In this case, it is possible that the door inner handle is still in a depressed state, and therefore, the steering restriction plate 1033 cannot be moved to the second position, and the motor 1034 keeps driving the steering restriction plate 1033 under the control of the controller 102, and when the door inner handle is not depressed (simply referred to as a return position), the steering restriction plate 1033 is moved to the second position under the drive of the motor 1034.
Fig. 5 is a flow of the controller in the intelligent door lock shown in fig. 1 for controlling unlocking, and assuming that the intelligent door lock is in a state that it cannot be unlocked from inside the door before the following steps are performed, fig. 5 includes the following steps:
s501: the pressure sensor detects whether it is pressed, if yes, S503 is performed, and if no, S501 is performed.
S502: the capacitance sensor detects whether a human body is in contact with the sensor, if so, S503 is executed, and if not, S502 is executed.
S503: and sending the sensing signal to a controller.
Specifically, the strength of the sensing signal sent by the pressure sensor is positively correlated with the sensed pressure value, and the strength of the sensing signal sent by the capacitance sensor is correlated with the areas of the finger distance sensor and the sensing plate sensor of the sensor.
S504: after the controller verifies that the induction signal passes through, the controller controls the motor to drive the steering limiting plate to move to the first position.
Specifically, the verification is passed, in which the strength of the sensing signal sent by the pressure sensor and the strength of the sensing signal sent by the capacitance sensor are both greater than corresponding thresholds.
S505: after the controller door inner handle is in the first position of the steering limiting plate for a preset time, the controller door inner handle controls the motor to drive the steering limiting plate to move from the first position to the second position.
As described above, if the inner door handle is depressed, the turn restriction plate can be moved to the second position only by the motor (but may not be moved to the second position), and if the inner door handle is not depressed, the turn restriction plate can be moved to the second position. After the steering limit plate moves to the second position, the inner door handle cannot be pressed down.
In summary, the function implementation scenario of the intelligent door lock shown in fig. 1 is as follows:
when the door is locked, if the user does not contact the inner handle of the door, the steering limiting plate is at the second position, and the door lock cannot be opened at the moment. Because the inductor is required to be controlled in an induction mode, the lock cannot be unlocked through the cat eye by using a special tool.
If the user wants to unblank, then the user need hold the door inside handle, and metal pressure sensor senses to press this moment, and capacitance sensor senses human contact, sends sensing signal to the controller, and controller control motor drive turns to the limiting plate and removes to the primary importance, and under this condition, the user presses the door inside handle downwards, and the door inside handle drives the handle switching-over piece and rotates, realizes unblanking. When user's hand left the interior handle, the interior handle controller no longer received the inductive signal, after the time of predetermineeing, controller control motor drive turned to the limiting plate and moves to the second position, and the lock can not be opened this moment.
Therefore, the metal pressure sensor and the capacitance touch sensor are adopted in the handle of the intelligent door lock product to realize the action of the mechanical transmission mechanism, the safety level of the cat eye unlocking prevention technology is improved, the user holds the handle to trigger the door lock to be changed from the unopened state to the openable state, the door lock more accords with the door opening habit action of the user, and the intelligent door lock has higher user use convenience.
