[0002] In the current market, intelligent locks, especially intelligent electronic locks with a vertical grip design, have potential pinch safety hazards.

[0047] To make the objectives, technical solutions and advantages of the present invention clearer and more explicit, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are merely used to explain the present invention and are not intended to limit the present invention.

[0048] There are safety hazards in the handle designs of some current smart locks. For example, the vertical-grip smart electronic lock is prone to pinching accidents, especially for groups such as children. The conventional design is to optimize the handle design by increasing the distance between the handle and the door frame to avoid pinching. However, this method requires high design requirements, needs to distinguish between left and right unlocking, affects the aesthetics of the appearance and increases costs. This approach not only has high design complexity and requires distinguishing between left and right unlocking directions, but may also affect the overall aesthetics of the product and increase manufacturing costs. Another part prevents users from reaching out in the wrong direction by adding a handle baffle to avoid pinching. However, this method not only affects the aesthetics but also the user experience, and requires additional partition accessories. As a result, in the case of unlocking with an incorrect gripping posture, the smart door lock cannot recognize the correct direction of the user's grip to unlock. Therefore, there is a need for an unlocking method based on an induction sensor. Using this method, induction sensors can be embedded on both sides of the vertical grip of the smart lock to identify the correct direction of the user's grip for unlocking, avoiding pinching while maintaining aesthetics.

[0049] The unlocking method based on an induction sensor according to a preferred embodiment of the present invention, as Figure 1 shown, the unlocking method based on an induction sensor includes the following steps:

[0050] Step S10: Obtain the key input by the user, verify the key to obtain a verification result, control the main tongue lock of the smart door lock to unlock according to the verification result, and control the auxiliary tongue lock of the smart door lock to lock to obtain an opening activation instruction.

[0051] Specifically, when the user attempts to unlock, the smart door lock verifies the key (face recognition and fingerprint recognition) to obtain a verification result. After verifying the key, according to the verification result, control the main lock tongue of the smart door lock to unlock, and control the auxiliary tongue lock (latch bolt or shear bolt) of the smart door lock not to unlock first. At this time, the door cannot be opened directly. When the user's hand approaches the handle, the induction sensors on both sides of the handle are activated.

[0052] Step S20: Activate the induction sensor of the smart door lock according to the opening activation instruction. After activation, the induction sensor senses and detects the user's gripping position to obtain an induction result. Based on the proximity induction algorithm, judge the direction of the gripping position according to the induction result to obtain the gripping direction.

[0053] As Figure 2As shown, the step S20 includes:

[0054] Step S21: When the distance between the user's hand and the handle of the intelligent door lock is less than a preset distance, any one or more of the capacitance induction sensors, the pressure induction sensors, and the infrared induction sensors on both sides of the intelligent door lock are activated according to the door-opening activation signal;

[0055] Step S22: Any one or more of the activated capacitance induction sensors, pressure induction sensors, and infrared induction sensors detect the user's holding position to obtain an induction result, and based on the proximity induction algorithm, the direction of the holding position is judged according to the induction result to obtain the holding direction.

[0056] Specifically, if the user's hand is less than a preset distance from the handle of the smart door lock, any one or more of the capacitive sensing sensors, the pressure sensing sensors and the infrared sensing sensors on both sides of the smart door lock are activated according to the door opening activation signal, and any one or more of the activated capacitive sensing sensors, the pressure sensing sensors and the infrared sensing sensors sense and detect the user's holding position to obtain a sensing result (sensing sensors are added on both sides of the vertical handle, such as capacitive sensing sensors, pressure sensing sensors and infrared sensing sensors, etc., and the capacitive sensing sensors, pressure sensing sensors and infrared sensing sensors can sense whether the hand is holding on the left or right), wherein the sensing result is used to verify whether the user's hand is placed in the holding position, and based on the proximity sensing algorithm, the direction of the holding position is judged according to the sensing result to obtain the holding direction (when the hand approaches the left or right capacitive sensing sensor, pressure sensing sensor and infrared sensing sensor, the capacitive sensing sensor, pressure sensing sensor and infrared sensing sensor are sensed by the capacitive sensing sensor, pressure sensing sensor and infrared sensing sensor). The capacitance value of the sensor increases, and the voltage or infrared light intensity increases, which is significantly different from not placing the hand, and based on this, it can be judged whether the hand is on the left or right side). The sensing sensor includes: any one or more of a capacitive sensing sensor, a pressure sensing sensor, and an infrared sensing sensor (the three sensing sensors can be alternatives to each other, and only one of them is built-in to achieve the same sensing effect, or more than two can be built-in at the same time to increase the detection dimension to enhance the accuracy of sensing judgment). The capacitive sensing sensor, the pressure sensing sensor, and the infrared sensing sensor are connected to the control unit via a wired manner to transmit the holding state data in real time. The sensing sensors are cleverly embedded on both sides of the vertical handle to ensure that when the user holds the handle, no matter what the size of the palm or the holding position is, it can be accurately detected. The positions of the capacitive sensing sensor, the pressure sensing sensor, and the infrared sensing sensor are accurately calculated to minimize false alarms and missed alarms. A non-contact (infrared sensor) method is used to detect the proximity of the user's hand to the handle, and the pressure sensor can sense the pressure distribution during holding. Both can effectively identify the holding state.

[0057] like Figure 3 As shown, the step S22 includes:

[0058] Step S221: the activated capacitive sensing sensor performs capacitive detection on the user's holding position to obtain a first sensing result, the activated pressure sensing sensor performs pressure detection on the user's holding position to obtain a second sensing result, and the activated infrared sensing sensor performs infrared detection on the user's holding distance to obtain a third sensing result;

[0059] Step S222: Based on the proximity sensing algorithm, determine the direction of the holding position according to any one or more of the first sensing result, the second sensing result, and the third sensing result, to obtain the holding direction.

[0060] Specifically, the activated capacitance sensing sensor performs capacitance detection on the user's holding position (capacitance sensing, when the hand approaches the capacitance sensing sensor, the capacitance value increases), to obtain the first sensing result; the activated pressure sensing sensor performs pressure detection on the user's holding position (the greater the deformation caused by the pressure, the greater the feedback voltage value), to obtain the second sensing result; the activated infrared sensing sensor performs infrared detection on the distance of the user's holding position (infrared sensing, when the hand approaches the infrared sensor, the intensity of the reflected infrared light increases), to obtain the third sensing result. Based on the proximity sensing algorithm, determine the direction of the holding position according to any one or more of the first sensing result, the second sensing result, and the third sensing result, to obtain the holding direction (the capacitance sensing sensor, the pressure sensing sensor, or the infrared sensing sensor can sense whether the direction of the hand holding is on the left or right side of the smart door lock), where the holding direction includes the left side and the right side of the smart door lock.

[0061] As Figure 4 shown, step S221 includes:

[0062] Step S2211: The activated capacitance sensing sensor performs capacitance detection on the direction of the holding position, to obtain a capacitance value, and determine the first sensing result according to the first preset threshold for the capacitance value;

[0063] Step S2212: The activated pressure sensing sensor performs pressure detection on the direction of the holding position, to obtain a feedback voltage value, and determine the second sensing result according to the second preset threshold for the feedback voltage value;

[0064] Step S2213: The activated infrared sensing sensor performs infrared detection on the distance of the direction of the user's holding position, to obtain a reflected light intensity value, and determine the third sensing result according to the third preset threshold for the reflected light intensity value.

[0065] Specifically, the activated capacitive induction sensor performs capacitive detection on the direction of the holding position to obtain a capacitance value, and judges the capacitance value according to a first preset threshold to obtain a first induction result (for the capacitive sensor, there is a base value when no hand is placed on it, and when a hand is placed on it, the capacitance value will increase. When designing, the system will build in a value, which is used as the threshold for judging whether a hand is placed on it. When the sensed value is greater than this value, it is considered that a hand is placed on it). The activated pressure induction sensor performs pressure detection on the direction of the holding position to obtain a feedback voltage value, and judges the feedback voltage value according to a second preset threshold to obtain a second induction result (for the pressure induction sensor, there is a base value when no hand is placed on it, and when a hand is placed on it, the feedback voltage value will increase. When designing, the system will build in a value, which is used as the threshold for judging whether a hand is placed on it. When the sensed value is greater than this value, it is considered that a hand is placed on it). The activated infrared induction sensor performs infrared detection on the distance in the direction of the user's holding position to obtain a reflected light intensity value, and judges the reflected light intensity value according to a third preset threshold to obtain a third induction result (for the infrared induction sensor, there is a base value when no hand is placed on it, and when a hand is placed on it, the reflected light intensity value will increase. When designing, the system will build in a value, which is used as the threshold for judging whether a hand is placed on it. When the sensed value is greater than this value, it is considered that a hand is placed on it).

[0066] Step S30: If the holding direction is the preset opening holding direction, then control the latch lock of the intelligent door lock to unlock, so that the user can be fully unlocked and opened when in the correct holding direction.

[0067] As Figure 5 shown, step S30 includes:

[0068] Step S31: Judge whether the left or right side of the intelligent door lock is the preset opening holding direction;

[0069] Step S32: If the left or right side of the intelligent door lock is the preset opening holding direction, then control the oblique latch or the scissors latch of the intelligent door lock to unlock, so that the user can be fully unlocked and opened when in the correct holding direction.

[0070] Specifically, it is determined whether the left or right side of the intelligent door lock is the preset opening and holding direction (the control unit is embedded with intelligent algorithms for analyzing the data of the capacitance induction sensor, pressure induction sensor, and infrared induction sensor to determine whether the holding direction is correct). If the left or right side of the intelligent door lock is the preset opening and holding direction, then the locking tongue or scissor tongue of the intelligent door lock is controlled to unlock (when the holding direction is correct, the control unit immediately triggers the unlocking process to unlock the scissor tongue or locking tongue), so that when the user is in the correct holding direction, the door can be fully unlocked and opened. If the capacitance induction sensor, pressure induction sensor, and infrared induction sensor detect that the direction of the handle held by the user is the correct opening direction (i.e., the preset opening and holding position), the system continues to execute the unlocking, such as releasing the locking of the locking tongue / scissor tongue to allow the door leaf to open; if it is detected that the holding direction is incorrect, the unlocking is immediately stopped, and the user is reminded to hold correctly again through sound and light. The bolt lock includes: a locking tongue or scissor tongue, that is, only the main locking tongue is unlocked after verifying the secret key, and the locking tongue / scissor tongue is not unlocked. At this time, the scissor tongue / locking tongue is not retracted, and the user still cannot directly open the door. When the user's hand is placed in the correct position, the scissor tongue / locking tongue is unlocked at this time to allow the user to open the door, otherwise it is prompted that the hand placement position is incorrect and the scissor tongue / locking tongue is not unlocked, which can effectively avoid the situation of pinching hands.

[0071] Further, after the step S31, it also includes that if the left and right sides of the intelligent door lock are not the preset opening and holding directions, then the locking tongue or scissor tongue of the intelligent door lock is controlled to pause the unlocking operation, and the user is reminded through a preset feedback mechanism (if the holding is incorrect, the user is informed through means such as sound alarm, mechanical vibration, and light prompt (such as the LED indicator flashing), and the unlocking operation is paused); wherein, the preset feedback mechanism includes: sound alarm, mechanical vibration, and light prompt. After the step S30, it also includes automatically adjusting the first preset threshold, the second preset threshold, and the third preset threshold respectively according to the first induction result, the second induction result, and the third induction result to obtain multiple first preset thresholds, multiple second preset thresholds, and multiple third preset thresholds; based on the proximity induction algorithm, calculating according to multiple first preset thresholds, multiple second preset thresholds, and multiple third preset thresholds to obtain the optimal first preset threshold, the optimal second preset threshold, and the optimal third preset threshold (the threshold is generally determined by the parameters during the debugging process, or the value when no hand is placed is automatically scanned, and generally multiple samples are taken and averaged, and then a little increment is added as the adaptive threshold), wherein, the preset feedback mechanism includes: sound alarm, mechanical vibration, and light prompt.

[0072] As Figure 6 and Figure 7 shown, by way of example, Figure 7The holding area of the intelligent door lock, where a capacitive induction sensor, a pressure induction sensor, and an infrared induction sensor are installed in the holding area. Figure 7 Below the holding area on the side is a hollow area, combined with Figure 6 In the case where the intelligent door lock is set on the right side of the door, if the user's hand is on the right side of the capacitive induction sensor, pressure induction sensor, and infrared induction sensor, there is a risk of being pinched by the door gap, and the holding direction is determined to be incorrect. Unlock is immediately stopped, and the user is reminded to hold correctly again through sound and light. If the user's hand is on the left side of the capacitive induction sensor, pressure induction sensor, and infrared induction sensor, the diagonal tongue / scissor tongue lock is released to allow the door leaf to open. Further, if the intelligent door lock is set on the left side of the door, if the user's hand is on the right side of the capacitive induction sensor, pressure induction sensor, and infrared induction sensor, the diagonal tongue / scissor tongue lock is released to allow the door leaf to open. If the user's hand is on the left side of the capacitive induction sensor, pressure induction sensor, and infrared induction sensor, the holding direction is determined to be incorrect, unlock is immediately stopped, and the user is reminded to hold correctly again through sound and light. Further, when the door lock is in the unlocked state and in the open door state, and the user holds the door lock handle to close the door, the door lock determines whether the user's hand-held direction is the correct direction according to the sensing of the induction sensor. If the direction is correct, the user is allowed to close the door and lock it normally. If the user's hand-held direction is incorrect, the user is reminded of the incorrect hand-held direction through sound alarm, mechanical vibration, and light prompt, and there is a risk of pinching the hand when closing the door.

[0073] Further, as Figure 8 shown, based on the above unlocking method based on the induction sensor, the present invention also correspondingly provides an unlocking system based on the induction sensor. Among them, the unlocking system based on the induction sensor includes:

[0074] The main tongue lock unlocking module 51 is used to obtain the key input by the user, verify the key to obtain a verification result, control the main tongue lock of the intelligent door lock to unlock according to the verification result, and control the auxiliary tongue lock of the intelligent door lock to lock to obtain an opening activation instruction.

[0075] The holding direction detection module 52 is used to activate the induction sensor of the intelligent door lock according to the opening activation instruction. The activated induction sensor senses and detects the user's holding position to obtain an induction result. Based on the proximity induction algorithm, the direction of the holding position is judged according to the induction result to obtain the holding direction.

[0076] The intelligent door lock unlocking module 53 is used to control the auxiliary tongue lock of the intelligent door lock to unlock if the holding direction is the preset opening holding direction, so that the user can fully unlock and open the door when in the correct holding direction.

[0077] Further, asFigure 9 As shown, based on the above-mentioned unlocking method and system based on an inductive sensor, the present invention also correspondingly provides an intelligent door lock, which includes a processor 10, a memory 20, and a display 30. Figure 9 Only some components of the intelligent door lock are shown, but it should be understood that it is not required to implement all the shown components, and more or fewer components can be alternatively implemented.

[0078] In some embodiments, the memory 20 can be an internal storage unit of the intelligent door lock, such as a hard disk or memory of the intelligent door lock.

The memory 20 is used to store application software installed on the intelligent door lock and various types of data, such as program codes for installing the intelligent door lock. The memory 20 can also be used to temporarily store data that has been output or will be output. In one embodiment, an unlocking program 40 based on an inductive sensor is stored on the memory 20, and this unlocking program 40 based on an inductive sensor can be executed by the processor 10, thereby implementing the unlocking method based on an inductive sensor in the present application.

[0080] In some embodiments, the display 30 can be an LED display, a liquid crystal display, a touch liquid crystal display, and an OLED (Organic Light-Emitting Diode) toucher, etc. The display 30 is used to display information on the intelligent door lock and to display a visual user interface. The components of the intelligent door lock communicate with each other through a system bus.
