Referring to fig. 1 to 6, an embodiment of the present utility model provides an electronic door lock, which includes an outer panel 1 installed on the outer side of a door panel 0, an inner panel 2 installed on the inner side of the door panel 0, and a lock body 3 embedded in the door panel 0.

The lock body 3 comprises a shell 6, a sealing cover (not shown), a positioning module 7 for stabilizing the orientation of the door plate 0 when the door is closed, and a main lock module 8 for locking the door; the positioning module 7 and the main lock module 8 are respectively arranged in the shell 6 and are fixedly connected with the shell 6 by a sealing cover for encapsulation; the main lock module 8 comprises a main lock tongue 9, a pushing plate 10, a main shaft 11, a deflector rod 12 and a main lock spring 13; the main lock tongue 9 is fixedly connected to the front end of the pushing plate 10, and the main lock tongue 9 and the pushing plate 10 are slidably connected to the shell 6, so that the main lock tongue 9 can extend or retract at the front end surface of the shell 6; the pushing plate 10 is provided with a pushing groove 14, the main shaft 11 is pivotally connected to the shell 6 and is opposite to the pushing groove 14, the deflector rod 12 is in transmission connection with the main shaft 11, and the end part of the deflector rod 12 is embedded in the pushing groove 14, so that the deflector rod 12 acts on the pushing groove 14 to drive the main lock tongue 9 to stretch and retract; a main lock spring 13 is mounted on the housing 6 to act on the lever 12.

A driving module 4 is arranged in the inner panel 2, and the driving module 4 is in transmission connection with a main shaft 11; the driving module 4 comprises a housing 15, a cover (not shown), a knob 16, a motor 17, a gear set, a rotating shaft 18 and a circuit board 19; the motor 17, the gear set, the rotating shaft 18 and the circuit board 19 are arranged in the housing 15, and are packaged by the housing, and the knob 16 exposed out of the inner panel 2 is in transmission connection with the rotating shaft 18 and is used for manually controlling the main lock tongue 9; the motor 17 is electrically connected with the circuit board 19, the motor 17 is in transmission connection with the rotating shaft 18 through a gear set, and the rotating shaft 18 is in transmission connection with the main shaft 11.

Control modules are respectively arranged on the outer panel 1 and the inner panel 2, and are electrically connected with the circuit board 19.

The working principle of the utility model is as follows: when the door is closed, the lock body 3 moves together with the door panel 0. When the door is completely closed, the positioning module 7 is matched with the door frame to stabilize the door plate 0 in a closed state, so that the door plate 0 is ensured not to shake and is positioned accurately. The driving module 4 is controlled to operate by an electronic program, and the motor 17 drives the main lock tongue 9 of the main lock module 8 to extend out through the gear set electric rotating shaft 18 so as to lock the door. Of course, the knob 16 of the driving module 4 can be manually operated, and the main bolt 9 is driven to move through transmission to perform manual switch lock.

It should be noted that, the electronic door lock of the present utility model has corresponding control functions as the control modules of the outer panel 1 and the inner panel 2 of the conventional electronic door lock, such as: coded locks, fingerprint identification, etc. Since the technical innovation of the present utility model is not the above module, it is not limited thereto.

When the main lock module 8 works, the main shaft 11 is driven by the motor 17 or the manual rotation knob 16, so that the deflector rod 12 is driven to swing by a corresponding angle. The deflector rod 12 acts on the pushing groove 14 to drive the pushing plate 10 to stretch back and forth, so as to drive the main lock tongue 9 to extend or retract to switch the lock. The main lock spring 13 is used for limiting the deflector rod 12, so that the deflector rod 12 is forced to stay only in an unlocking or locking position and cannot shake freely, and the state of the main lock tongue 9 is limited. Meanwhile, when the main shaft 11 is rotated, a 'clicking' stirring hand feeling is provided, a gear feeling is created, and the feeling is finally transmitted to the knob 16 through transmission, so that the state of the main lock tongue 9 is perceived in an auxiliary mode.

It should be noted that the form of the main lock tongue 9 is not limited to the single straight strip shown in the drawings of the specification, and more shape changes can be made as required.

The structure of the lock body 3 of the present utility model is optimized and co-operates with it by means of a drive system.

First, it has abandoned traditional quick-opening concept, has saved traditional lock body 3's oblique tongue, no longer need install door handle and oblique tongue linkage, and the user opens the door and can select operation front panel or rear panel to open the door automatically, even adopts manual mode of opening the door also no longer need with great strength push down the rotation door handle, but operate knob 16 and unblank, has improved user's use experience.

Second, its main lock module 8 reduces the number of turns required to switch the lock. The main shaft 11 drives the deflector rod 12 to swing, and the rotation angle of operation is generally controlled within 180 degrees, so that the motor 17 can switch the lock only by running for a short time when the driving module 4 operates. The method not only brings more convenient user experience, but also reduces energy consumption and ensures longer duration of the battery. When the manual switch lock is operated, the manual switch lock only needs to rotate by a small angle, and the manual switch lock is more in line with the rotation range of the wrist of a human body and is more comfortable to experience.

Third, it simplifies the structure inside the lock body 3, makes the lock body 3 smaller, facilitates installation on a thinner door panel 0, and reduces costs.

Referring to fig. 3 to 4, preferably, the circuit board 19 is provided with at least two inductors 20 distributed in different directions, and the rotating shaft 18 is provided with a sensing terminal 21 in a transmission connection with the inductors 20, so that the sensing terminal 21 triggers the inductors 20 to send sensing signals when the rotating shaft 18 rotates to different directions.

The orientation of the sensor 20, corresponding to the orientation of the sensing terminal 21 of the spindle 18 when the lock is opened and closed, can be used to sense the orientation of the spindle 18, and thus control the motor 17. On the one hand, it controls the telescopic condition of the main latch 9; on the other hand, it controls the rotational orientation of the knob 16.

Further, the sensor 20 is provided with at least three sensors respectively distributed on two sides and the middle. The design is mainly used for enabling the door lock to have the function of automatically identifying whether the door lock is applied to left door opening or right door opening.

For example: the door is installed by opening the door left or right, so that the driving module 4 is operated, and the motor 17 is operated in opposite directions. When the driving module is provided with at least three sensors 20, and is located at two sides and middle, respectively, the driving module 4 can execute an initial recognition procedure: the motors 17 respectively rotate left and right, and if the left rotation process can rotate and the right rotation process is dead, the left opening is identified; and otherwise, the right opening is identified.

Referring to fig. 3 to 6 in detail, further, the gear set includes a main gear 22 and an intermediate gear set 23, the motor 17 is in transmission connection with the main gear 22 through the intermediate gear set 23, and the main gear 22 is in transmission connection with the rotating shaft 18; wherein, the main gear 22 is provided with an arc groove 24, the rotating shaft 18 is provided with a transmission key arranged in the arc groove 24, and the size of the arc groove 24 is larger than that of the transmission key, so that the transmission between the main gear 22 and the transmission key has a section of idle running stroke.

The provision of the arcuate slot 24 allows for a brief disengagement of the drive between the shaft 18 and the main gear 22, which allows room for manual operation of the in-situ knob 16, avoiding jamming during manual rotation of the knob 16.

For example: when the motor 17 controls the door to be locked, the main lock tongue 9 is extended Guan Suowei, and the corresponding rotating shaft 18 is rotated to a corresponding direction, and at this time, the main lock tongue can be detected by the sensor 20. The motor 17 can adjust the rotation angle of the main gear 22 to separate the end surface of the arc-shaped slot 24 from the transmission key. Thereafter, if the user wants to unlock the lock manually, the knob 16 can be rotated to drive the rotating shaft 18 to rotate, and the transmission key is separated from the end face of the arc-shaped groove 24, so that the transmission key and the arc-shaped groove are actually separated from transmission, and the rotating shaft 18 is idle in the process of rotating the knob 16, so that the situation of jamming can not occur. This also benefits from the simplification of the main lock module 8, which reduces the required angle of rotation of the main shaft 11 of the switch lock and thus the rotation of the spindle 18.

Referring to fig. 2 in detail, the positioning module 7 includes a positioning lock tongue 25 and a lock tongue spring 26; the positioning lock tongue 25 is slidably connected to the housing 6, so that the front end of the positioning lock tongue 25 can extend or retract from the front end surface of the housing 6, and a lock tongue spring 26 is arranged between the positioning lock tongue 25 and the housing 6.

When the door is completely closed, the positioning lock tongue 25 of the positioning module 7 is firstly jacked into the lock body 3 by the door frame and then stretches into the door frame again, so that the door plate 0 is stabilized in a closed state, and the door plate 0 is ensured not to shake and is accurately positioned.

Preferably, a mechanical lock core 5 is arranged in the outer panel 1, and the mechanical lock core 5 is in transmission connection with the main shaft 11 so as to retain the basic function of unlocking the door by a key.

Further, the lock body 3 is further provided with a detection module 27.

In a first preferred embodiment, the detection module 27 includes a detection lock tongue 28, a return spring 29, and a detection switch 30; the detection lock tongue 28 is connected with the shell 6 in a sliding way, so that the detection lock tongue 28 can extend or retract at the front end face of the shell 6; the detection switch 30 is fixedly arranged on the shell 6 and is opposite to the tail part of the detection lock tongue 28, so that the detection lock tongue 28 is contracted to trigger the detection switch 30; a return spring 29 is arranged between the detection bolt 28 and the housing 6.

The detection module 27 is triggered by adopting a mechanical structure, so that the reliability is high. When the door is closed, the detection bolt 28 is compressed, the detection switch 30 sends out an identification signal, the system identifies the state of the door as closed, and immediately and rapidly controls the main bolt 9 to extend out for locking the door.

Or referring to fig. 7, as another preferred embodiment, the detection module 27 includes a magnetic induction switch 31; the magnetic induction switch 31 is mounted on the front end surface of the housing 6. When the magnetic induction switch 31 is applied, the magnet is fixedly arranged at the position of the door frame, which is right opposite to the magnetic induction switch 31, so as to assist the work of the magnetic induction switch 31. When the door is fully closed, the magnetic induction switch 31 is opposite to the magnet, thereby triggering the induction signal to recognize that the state of the door is closed. The scheme of the magnetic induction switch 31 can further simplify the structure of the lock body 3, so that the lock body 3 is simpler.

Furthermore, a positioning switch (not shown) is provided on the housing 6 opposite to the tail of the positioning bolt 25, so as to assist in detecting the door closing state. For example, if the door is not normally closed, but the detection module 27 is already activated by the door frame, the system recognizes that the door is not normally closed, and the door is not normally closed even if the door locking operation of the main lock module 8 is performed, and the service life of the main lock module 8 may be seriously affected. The positioning switch can assist in recognition, so that the recognition is more accurate, and the problems are avoided. It is possible to further detect the state of the positioning tongue 25, thereby assisting in more accurately identifying the true state of the door.

The electronic door lock provided by the utility model improves the structure of the lock body 3, simplifies the structure of the main lock module 8, can realize the opening and closing of the lock by only small-amplitude rotation, shortens the operation time of the driving module 4, has lower energy consumption and is convenient for a manual operation mode. The automatic detection device has various detection functions, assists in automatic control, greatly improves the automatic performance and improves the user experience. The simpler lock body 3 has a smaller volume, which makes the door lock product advantageous for application on thinner door panels 0.
