Description

Technical Field

[0001] The present invention relates to the technical field of intelligent door locks, and in particular to an electronic handle lock for anti-theft doors of student dormitories and office spaces and a control method thereof. Background Art

[0002] At present, there are some functional problems in the use of smart door locks in school student dormitories and office spaces. First, the current smart door lock tongue is in a normally closed mode (i.e., the door is locked when the door is closed), and it needs to be driven and unlocked multiple times when the door is opened, which will cause a large amount of power consumption of the electronic lock, and the dry batteries for power supply need to be replaced frequently. In addition to causing a waste of funds, improper disposal of waste batteries will also affect the environment, which is very environmentally unfriendly; second, after the safety lock tongue of the existing door lock is activated in the room, outsiders cannot open it. In this way, when someone needs to visit or the people in the same dormitory return to the room, the inside personnel need to unlock the door to open it. In an emergency, the door cannot be opened for emergency rescue, which will seriously affect the management of student dormitories and office spaces. Therefore, the present invention proposes an electronic handle lock and control method for anti-theft doors of student dormitories and office spaces to solve the problems existing in the prior art. Summary of the invention

[0003] In view of the above problems, the purpose of the present invention is to propose an electronic handle lock and control method for anti-theft doors in student dormitories and office spaces. The electronic handle lock and control method for anti-theft doors in student dormitories and office spaces are triggered by a clutch mechanism set up and a motor control board and multiple groups of detection switches. After locking the door indoors, authorized personnel can authenticate and unlock the door outdoors, which is convenient for use in collective living and office scenarios. There is no need to start the electronic lock each time the door is opened, no energy consumption is required, and the frequency of dry battery replacement is reduced. At the same time, it can also facilitate escape in an emergency and achieve rapid and safe evacuation of personnel.

[0004] To achieve the purpose of the present invention, the present invention is implemented through the following technical solutions: an electronic handle lock for anti-theft doors of student dormitories and office places, comprising a main lock body, a square shaft, a front panel, a rear panel, an outer handle, an inner handle and a connecting plate, the main lock body is provided with a square shaft, the front panel and the rear panel are symmetrically provided on the front and rear sides of the main lock body, the main lock body also comprises a movable lock tongue and a main lock tongue, the main lock tongue is driven by the square shaft, the front side surface of the front panel is provided with an outer handle, the rear side of the rear panel is provided with an inner handle, the outer handle and the inner handle extending into the front panel and the rear panel are both provided with a connecting plate, the inner side of the front panel is provided with a front bracket, the upper part of the front bracket is provided with a main circuit board, the outer side of the main circuit board is electrically connected to the biometric identification module, the card identification module and the password verification module on the front panel, the lower side of the front bracket is symmetrically provided with a first detection switch, the front panel and the lower side of the square shaft are provided with a clutch mechanism, the rear panel is provided with a rear bracket, the lower part of the rear bracket is symmetrically provided with a second detection switch and a third detection switch, and the inner side of the rear panel is also provided with a motor control board.

[0006] A further improvement is that a signal output port is provided on the motor control board, and the signal output port is electrically connected to the clutch motor. A signal input port is also provided on the motor control board, and a motor signal port is provided on the main circuit board, and the motor signal port is electrically connected to the signal input port.

[0007] Further improvements are: the main circuit board is respectively provided with an unlocking signal port and a locking signal port, the second detection switch is electrically connected to the unlocking signal port, the first detection switch and the third detection switch are electrically connected to the locking signal port, and when the door lock is installed, the two symmetrical groups of the first detection switches connect the first detection switch on the opposite side with the locking signal port according to the direction of the outer handle, while the other side is not connected. The interlocking of the first detection switch and the third detection switch only reacts once. After the first detection switch is touched outdoors to unlock the door, there will be no reaction if the third detection switch is touched indoors, and no power consumption will be generated.

[0008] A further improvement is that a battery box is provided on the upper side of the rear bracket inside the rear panel for installing dry batteries to power the entire door lock. A power port is also provided on the motor control board, and the power port is electrically connected to the battery box, and the battery box is also electrically connected to the main circuit board.

[0009] A control method for electronic handle locks of anti-theft doors in student dormitories and office spaces: When the user locks the door outdoors, the user lifts the outer handle upward to drive the connecting plate to touch the first detection switch; The first detection switch sends a lock signal to the lock signal port, and then the main circuit board sends a motor reverse control signal to the motor control board; The motor control board controls the clutch motor to reverse and lower the motor push rod, so that it disengages from the clutch and puts the outer handle in a free state, thus forming a locked door state.

[0010] Further improvements are: when the user unlocks the door outdoors, an unlocking signal is generated by fingerprint, password and card verification, and the unlocking signal port on the main circuit board sends a motor forward control signal to the motor control board; The motor control board controls the clutch motor to rotate forward to raise the motor push rod, which contacts the clutch to form a linkage, so that the outer handle is out of the free state. Pressing the outer handle down drives the square shaft to rotate so that the clutch is linked to rotate synchronously, and the main lock tongue is retracted to unlock.

[0011] A further improvement is that when the user locks the door indoors, the user lifts the inner handle to drive the connecting plate to touch the third detection switch; The third detection switch sends a lock signal to the lock signal port, and then the main circuit board sends a motor reverse control signal to the motor control board; The motor control board controls the clutch motor to reverse and lower the motor push rod, so that it disengages from the clutch and puts the outer handle in a free state, thus forming a locked door state.

[0012] A further improvement is that when the user unlocks the door indoors, the user pulls down the inner handle to drive the connecting plate to touch the second detection switch; The second detection switch sends an unlock signal, and the unlock signal port on the main circuit board sends a motor forward control signal to the motor control board; The motor control board controls the clutch motor to rotate forward to raise the motor push rod, which contacts the clutch and makes the outer handle out of the free state. Pressing the outer handle down drives the square shaft to rotate so that the clutch rotates synchronously and the main lock tongue retracts to unlock the lock.

[0013] The beneficial effects of the present invention are as follows: the present invention is convenient for use in collective living and office scenes by setting a clutch mechanism and a motor control board and multiple groups of detection switches, thereby improving the comfort of using the product. At the same time, the electronic lock does not need to be activated each time the door is opened, and energy consumption is not required, thereby reducing the frequency of replacing dry batteries, and reducing the workload of handling waste batteries, thereby making a contribution to energy conservation and environmental protection. At the same time, there will be no problem that other people with unlocking authority cannot open the door because someone locks the door, which can prevent management accidents caused by intentional or accidental situations. It can also facilitate escape in an emergency and realize rapid and safe evacuation of personnel, which is particularly beneficial for places of collective living and learning.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0019] With the continuous development and improvement of the economic level, the door locks of collective office places and dormitory schools of all levels and types are undergoing upgrades and changes, developing towards convenience and intelligence. At present, many schools have upgraded the traditional simple padlocks and handle mechanical locks to handle electronic locks, etc., which not only improve the safety performance of the locks, but also incorporate more modern technological elements in the unlocking aspect to facilitate the use of users.

[0020] In the process of managing the students living in the dormitory, the managers of the school dormitory found that the traditional electronic locks for anti-theft door handles on the market have functions that are not suitable for use in collective dormitories. There are two major problems that bother users: First, the normally closed mode of the active lock tongue of the lock (closing the door means locking the door) brings unnecessary trouble to the normal life of the people in the dormitory; second, after the students activate the safety lock tongue in the dormitory, the people in the same room must open the safety lock tongue before they can return to the room. Even in case of emergency, the dormitory managers cannot open the door lock (even with keys) for emergency rescue. After the safety lock is locked indoors, no one can open the lock, and the door locks at home are like this. But this brings management and safety problems to public places.

[0021] The same problem also exists in office places. First of all, the ordinary anti-theft door handle electronic lock on the market locks the door when closing the door. It needs to be unlocked again when opening the door, and it will automatically lock again after a few seconds of unlocking. Locking again means that the handle is converted into a free handle. Pressing the handle down outside cannot drive the lock body, and the lock tongue will not retract, forming a locked door state. After closing the door, it cannot be opened unless it is unlocked again. After unlocking, turning the outside handle can drive all the lock tongues to retract, and then automatically convert to a free state. This is the normally closed mode of ordinary electronic locks. Every time an outsider visits, the person inside the house needs to open the door, which is troublesome to use. Another problem brought about by this is that frequent activation of electronic locks will consume a lot of electricity. Electronic locks are basically powered by dry batteries. In most situations, the batteries need to be replaced every six months. Excessive consumption of dry batteries not only wastes money, but also is not environmentally friendly to handle used batteries.

[0022] There are electronic locks on the market that can choose a normally open mode, but you need to enter the management program to set it up. When you need to lock the door, you need to cancel the normally open mode before you can lock the door. After unlocking, you must set it up again to enter the normally open mode. It is cumbersome and inconvenient to use.

[0023] Secondly, the common electronic locks for anti-theft door handles on the market use a standard 6068 lock body with three lock tongues, namely the live lock tongue, the main lock tongue and the safety lock tongue. When you need to lock the door backward, twist the safety lock tongue, and the door cannot be opened from the outside, thus achieving the effect of reverse locking. However, no one outside can open the lock, even if various unlocking methods including mechanical keys are used. This situation is still acceptable for home use, but it is very unfriendly to use it in public office spaces. First of all, there are many people in the office space, so this function cannot be used. At least an administrator must be able to open the lock to ensure sharing and safety in public places. Secondly, in the case of reverse locking, in the event of emergency situations such as fire and earthquake, personnel are required to open the door quickly to achieve one-press escape, but it is easy to misoperate in a panic and waste precious escape time.
