Technical Field
The utility model belongs to the technical field of the intelligent door lock discernment technique of unblanking and specifically relates to a recognition device that two-sided discernment was unblanked.
Background
With the continuous development of science and technology, intelligent door locks have become increasingly popular in various countries. The type of the intelligent door lock has various unlocking modes, wherein two modes of knob type mechanical driving and button electronic driving are mainly adopted for the indoor door opening mode of the push-pull type intelligent door lock, when a user uses the door opening mode, the operation needs to be carried out in two steps, firstly, a knob is twisted or a button is clicked, secondly, a door lock handle is held to push and pull the door, and the door opening operation is complicated; in addition, the traditional knob and button unlocking mode is simple in design and triggering, the problem of unlocking through a cat eye to the outside cannot be avoided, and certain potential safety hazards are provided.
Disclosure of Invention
To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a recognition device that two-sided discernment was unblanked.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a recognition device that two-sided discernment was unblanked, includes the push-and-pull handle, the push-and-pull handle includes protecgulum, center and back lid, be provided with the circuit board with door lock master control electric connection on the center, be provided with human infrared sensor and first touch sensor between protecgulum and the center, infrared sensor and first touch sensor arrange side by side each other, the induction surface subsides of first touch sensor are applied in the medial surface of protecgulum, be provided with second touch sensor between back lid and the center, the induction surface subsides of second touch sensor are applied in the medial surface of back lid, infrared sensor, first touch sensor and second touch sensor all with circuit board electric connection.
Preferably, the first touch sensor and the second touch sensor are both capacitive touch sensors.
Preferably, the front cover is provided with a light-transmitting window at the position opposite to the human body infrared sensor, and the light-transmitting window is sealed by a material which can transmit infrared beams.
Due to the adoption of the scheme, the utility model discloses a set up first touch sensor and second touch sensor simultaneously at the front and the back of the push-and-pull handle of lock, thereby only when holding here, according to the change of capacitance value, just can trigger first touch sensor and second touch sensor simultaneously, realize two-sided response, avoid under the mistake bumps or other non-unblanking circumstances, give the wrong recognition of unblanking; and whether combine human infrared sensor to survey push-and-pull handle positive direction and have operating personnel for the whole body forms diversified discernment and detects, ensures that indoor personnel unblank, stops outdoor unblanking, improves the security.
Drawings
Fig. 1 is a schematic perspective view of an embodiment of the present invention.
Fig. 2 is a schematic structural view of the inside of the push-pull handle according to the embodiment of the present invention.
Fig. 3 is a schematic view of the one-hand grasping unlocking recognition of the embodiment of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in fig. 1 to 3, the identification device that this embodiment provided unblanks of two-sided discernment, including push-and-pull handle 1, push-and-pull handle 1 includes protecgulum 2, center 3 and back lid 4, be provided with on the center 3 with lock master control electric connection's circuit board 5, be provided with human infrared sensor 6 and first touch sensor 7 between protecgulum 2 and the center 3, infrared sensor 6 and first touch sensor 7 arrange side by side each other, first touch sensor 7's response face pastes in the medial surface of protecgulum 2, be provided with second touch sensor 8 between back lid 4 and the center 3, second touch sensor 8's response face pastes in the medial surface of back lid 4, infrared sensor 6, first touch sensor 7 and second touch sensor 8 all with circuit board 5 electric connection.
Further, the first touch sensor 7 and the second touch sensor 8 are both capacitive touch sensors.
Further, the front cover 2 is provided with a light-transmitting window 9 at the opposite side of the human body infrared sensor 6, and the light-transmitting window 9 is sealed by a material which can transmit infrared beams.
The main functions of the embodiment are realized, the first touch sensor 7 and the second touch sensor 8 are arranged on the front surface and the back surface of the push-pull handle 1 of the door lock at the same time, so that only when the door lock is held by a hand, the first touch sensor 7 and the second touch sensor 8 can be triggered at the same time according to the change of capacitance values, double-sided induction is realized, and the mistaken identification of unlocking is avoided under the conditions of mistaken touch or other non-unlocking conditions; and whether combine human infrared sensor 6 to survey push-and-pull handle positive direction and have operating personnel for the whole body forms diversified discernment and detects, ensures that indoor personnel unblank, stops outdoor unblanking, improves the security.
During the concrete implementation, the circuit board 5 of installation on center 3 at first need with the inside master control procedure of intelligent lock constitution circuit to lead to, and in the authentication of unblanking discernment, only when all discernment of three sensor passes through, just send the instruction of unblanking to the lock master control procedure by circuit board 5. The double-sided position layout of the first touch sensor 7 and the second touch sensor 8 can effectively perform double-sided identification, when a human body needs to be unlocked, the human body is most directly grasped by a single hand, the thumb can be placed on the front cover 2, the other fingers can be placed on the rear cover 4 under specific operation, the first touch sensor 7 and the second touch sensor 8 can be simultaneously triggered according to the change of the capacitance difference value, and when the person needs to be unlocked, the person is necessarily located right opposite to the door lock, and then the human body infrared sensor 6 is utilized to determine whether the person who is unlocked is located right in front of the door lock. The unlocking can be carried out only when the three sensors are identified to pass through, and only when one sensor or two sensors are identified to pass through, the misoperation can be judged, and the door lock is not unlocked.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
