Background

In recent years, with the development of science and technology, door locks are developed from first mechanical locks to various types such as electronic locks and smart locks. The traditional mechanical lock completely depends on a key to open and close the door lock, while the intelligent door lock can be opened and closed by various modes such as fingerprints, digital keys, an induction card and the like. Generally, a motor is adopted as a driving element of the intelligent door lock, the motor drives a lock cylinder to move through a speed reducer, and then the lock cylinder drives a lock head of a lock body to move, so that the door lock is unlocked. In order to quickly open the door lock in an emergency, an emergency handle system is further arranged on the inner side of the intelligent door lock. The emergency handle system is characterized in that an indoor emergency knob drives a lock head to move through a linkage component, so that the door lock is unlocked. When the fingerprint or the password key and the emergency knob drive the lock body at the same time, the motor or the reducer is burnt, or the reducer (a worm and gear speed reducing system or a gear speed reducing system) directly bites the gear to damage or directly destroys the linkage mechanism of the lock body, so that the door lock cannot be normally opened.

The intelligent door lock in the prior art comprises an outdoor lock, an indoor lock and a lock body. The outdoor lock is installed on the surface of the door body facing the outside, the lock body is installed in the door body, and the indoor lock is installed on the surface of the door body facing the inside. Generally, a driving device installed inside the indoor lock (on a side close to the door body) drives the lock cylinder in the lock body to move through the second linkage assembly, so that the lock head in the lock body extends or retracts, and the door is closed or opened. In order to enable a user to rapidly open a door indoors under emergency conditions, an emergency handle system is usually arranged on an indoor lock, and an emergency knob installed on the outer side (far away from one side of a door body) of the indoor lock is rotated to drive a lock head of a lock body to retract through a first linkage assembly, so that the unlocking state of the intelligent door lock is realized. The first and second linkage assemblies are similar to those in existing intelligent door locks and will not be described in detail herein.

Example one

Emergent handle components mainly include emergent knob and outage mechanism, and outage mechanism is used for realizing the outage operation to drive arrangement to at the rotatory in-process of emergent knob, drive arrangement can't normally work, and at this moment, outdoor relevant personnel are through unblanking the module such as biological characteristics such as fingerprint or people's face, perhaps digital key input password form realizes unblanking, thereby avoid drive arrangement and emergent knob simultaneous working to cause the damage of drive arrangement or/and linkage assembly etc..

As an implementation mode, the unlocking module is matched with the control circuit board, and the control circuit board (the core device is a processor) receives a signal obtained by a user based on the conversion of the unlocking module, so as to judge whether to control the driving device to drive the second linkage assembly to work. Therefore, the control circuit board can be used as a matching device of the power-off mechanism.

The power-off mechanism can be realized by adopting an angle detection mechanism, such as an angle sensor, a photoelectric sensor or a proximity switch. The angle detection mechanism is installed on the rotary button, when the angle detection mechanism detects that the rotary button deviates from a plurality of angles of the initial position, for example, 10 degrees and the like, signals are sent to a processor of the control circuit board, the control circuit board controls the driving device to be powered off, of course, the angle detection mechanism can continuously send electric signals to the processor, and due to the fact that the electric signals corresponding to different angles are different in size, a threshold value can be set, when the electric signals sent to the processor by the angle detection mechanism are larger than the threshold value, namely, the rotation angle of the rotary button is determined to be larger than the preset angle, and the control circuit board controls the driving device to be powered off.

For example, fig. 1 shows a schematic structural diagram of a processor control driving device of a control circuit board, an angle detection mechanism sends an electrical signal to a processor, when the electrical signal sent to the processor by the angle detection mechanism is greater than a preset threshold, it is determined that a rotation angle of a rotary button is greater than a preset angle, no matter whether an unlocking module sends a signal to the control circuit board, the processor controls the driving device to be continuously powered off by controlling the electronic switch to be turned off, until the electrical signal sent to the processor by the angle detection mechanism is less than the preset threshold, and the signal sent to the control circuit board by the unlocking module causes the processor to control the electronic switch to be turned on, so that the driving device can work.

For another example, referring to fig. 2, assuming that the electronic switch is turned on when the processor outputs a high level, an and gate may be added to a connection line between the normal driving device and the processor, when the output terminal of the angle detection mechanism is connected to the negative input terminal of the comparator, the reference voltage (i.e., the voltage of the preset threshold) is connected to the positive input terminal of the comparator, the output terminal of the comparator and the connection line between the processor and the driving device are respectively connected to the two input terminals of the and gate, and the output terminal of the and gate is connected to the electronic switch.

When the electric signal generated by the angle detection mechanism is greater than the preset threshold value, the comparator outputs a low level, and the AND gate outputs a low level, so that at the moment, no matter whether the unlocking module enables the processor to output a high level to the AND gate, the electronic switch is always in an off state, and the driving device cannot work.

And when the electric signal generated by the angle detection mechanism is smaller than a preset threshold value, the comparator outputs a high level, if the unlocking module enables the processor to output the high level to the AND gate, the AND gate outputs the high level, the electronic switch is switched on, the driving device works, and the driving device can be opened through the second linkage assembly.

As another implementation mode, when the emergency knob acts, the driving device does not work in a mode that the emergency knob drives the switch to act.

Referring to fig. 3 and 4, the power cut-off mechanism includes a driving block 72 and a switch assembly, wherein the driving block rotates with the rotation of the emergency knob, when the driving block rotates to a certain angle, the switch assembly can be opened or closed, and the switch assembly can be connected to the control circuit board or the connection line between the power supply and the driving device.

For example, fig. 5 shows a schematic structure diagram of a processor connected to a control circuit board, one end of a switch assembly is connected to an input end of the processor, and the other end is grounded (of course, the switch assembly may also be connected to an auxiliary power supply), so that when a driving block touches the switch assembly, if the switch body of the switch assembly is disconnected due to touch, a port input signal connected to the switch assembly by the processor is converted from a low level to a high level, which indicates that an emergency knob is working, and the processor controls the driving device to power off. Similarly, if the touch closes the switch body, the processor can control the driving device to be powered off.

When the switch assembly is connected between the power supply and the driving device, the driving block 72 rotates to touch the switch assembly, the switch body is disconnected, so that the power supply does not supply power to the driving device any more, after the driving block 72 is reset, the switch body is closed, and whether the driving device works depends on whether the switch module can enable the processor to control the driving device to work.

In a preferred embodiment, the emergency knob 74 includes a hand-held portion and a rotating portion fixedly connected or integrally formed with the hand-held portion, and the driving block 72 is fixedly connected to the rotating portion by a screw.

When the indoor lock is in use, the handheld part is positioned on the outer side of the indoor lock, one end of the rotating part is fixedly connected with the handheld part, and the other end of the rotating part penetrates through the indoor lock and extends to the inner side of the indoor lock. The driving block is fixedly connected with the rotating part, and the specific connection mode can be as follows: a groove is formed in one end, far away from the hand holding part, of the rotating part; the one end that the driving block is close to the rotation portion is equipped with the axial lug, the axial lug with the recess matches for in the axial lug just imbeds the recess, rethread screw 75 will rotate portion and driving block fixed connection.

The switch assembly is mounted inside the indoor lock and may include a switch contact 611 and a switch body 61 connected between the power source and the driving device, or one end of the switch body is grounded and the other end is connected to the input of the processor.

When the emergency button rotates, the driving block is driven to rotate, when the driving block rotates to a certain angle, the switch contact is touched, so that the switch contact touches the switch body to act (open or close), and the switch body can be realized by using the micro switch. Of course, in some other embodiments, the switch body may also use a proximity switch, etc., and when using a proximity switch, the proximity switch may be mounted on the switch contact.

In order to enable the emergency knob to abut against the switch contact when the emergency knob rotates to a certain angle, the periphery surface of the driving block is an abutting curved surface, and the end parts of two sides of the radial section (the vertical direction of the rotating shaft) of the abutting curved surface are gradually lifted towards the middle part.

In some other embodiments, the panic handle assembly further comprises a reset mechanism for automatically resetting the rotated panic knob to an initial state. The return mechanism can be implemented in a variety of ways, such as by a torsion spring 73.

The emergency knob rotates, and the lock head of the lock body can be driven to act through the first linkage mechanism. In the preferred embodiment of the present invention, the emergency knob is engaged with the first linkage mechanism through a square steel, specifically, a square steel hole 70 is opened in the axial direction of the driving block, and the screw 75 is screwed to the rotating part through the bottom of the square steel hole. The size and the square steel hole looks adaptation of square steel, square steel 71's one end is pegged graft in the square steel hole, and the other end extends to the square steel hole outside (this outside is for keeping away from the one side of rotation portion) to pass the tapered end, be connected to outdoor lock, first link gear installs on the square steel, and when the square steel rotated, first link gear drive tapered end stretched out or retracted.
