[0001] Embodiments of the present disclosure relate to the technical field of door lock, in particular to a door lock and a door. BACKGROUND

[0002] In recent years, with the rapid development of science and technology, the functions of door locks have become diversified. The detection of the opening and closing state of the door is one of them. At present, the function of detecting the opening and closing state of the door mainly relies on adding a gyroscope sensor in the door lock panel.

[0003] However, when detecting the opening and closing state of the door in the above manner, the following problems often exist: when the user's door opening and closing action is slight, the gyroscope sensor cannot timely sense the movement of the door, and in addition, the positioning accuracy of the gyroscope sensor is not high, which may cause false positives, resulting in that the door lock cannot normally detect the opening and closing state of the door. CONTENT OF THE UTILITY MODEL

[0004] The summary part of the present disclosure is used to introduce the concepts in a brief form, which will be described in detail in the specific embodiments part. The summary part of the present disclosure is not intended to identify the key features or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions. Some embodiments of the present disclosure propose an intelligent door lock with a detection device and a door to solve one or more of the technical problems mentioned in the background part.

[0005] In a first aspect, some embodiments of the present disclosure provide a door lock, comprising: a lock body, a lock tongue fixing plate and a buckle plate, wherein the lock body comprises a lock tongue; the lock tongue fixing plate is provided with a first lock tongue through hole; the buckle plate is provided with a second lock tongue through hole; the buckle plate is used to be installed on a door frame and is correspondingly arranged with the lock tongue fixing plate; the lock tongue fixing plate is provided with a magnetic sensor; the buckle plate is provided with a magnet; the magnetic sensor and the magnet are oppositely arranged; and the magnetic sensor is electrically connected with a lock body control unit.

[0013] Optionally, the lock body control unit is further provided with a fault counter.

[0014] In the second aspect, some embodiments of the present disclosure provide a door, which comprises a door body and a door lock as described in the first aspect.

[0015] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the door lock of some embodiments of the present disclosure, the detection accuracy of the door lock on the door opening and closing state can be improved. Specifically, the reason why the detection accuracy of the door lock on the door opening and closing state is poor is that the function of the door lock to detect the door opening and closing state mainly relies on the addition of a gyroscope sensor in the door lock panel, and when the user's door opening and closing action is slight, the gyroscope sensor cannot timely sense the movement of the door, and in addition, the positioning accuracy of the gyroscope sensor is not high, which may cause false positives, resulting in that the door lock cannot normally detect the opening and closing state of the door.

[0024] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0025] Figure 1 is a structural schematic diagram of a door lock according to some embodiments of the present disclosure. Figure 1 It includes a buckle plate 1, a magnetic sensor 2, a sensor head 201, a connecting line 202, a plug 203, a lock body 3, a lock tongue fixing plate 4, a magnetic sensor fixing hole 5, a first lock tongue passing hole 6, a second lock tongue passing hole 7, a magnet mounting hole 8, a first type fixing hole 9, a second type fixing hole 10, a magnet 11, a lock tongue 12.

[0026] In some embodiments, the door lock can include a lock body 3, a bolt fixing plate 4 and a buckle plate 1. The lock body 3 can include a bolt 12. In use, the bolt 12 can extend from the lock body 3 into the door frame to achieve the function of locking the door. The bolt fixing plate 4 can be used to fix the lock body 3 to the door so that the lock body 3 can move with the opening and closing of the door. The bolt fixing plate 4 can be provided with a first bolt passing hole 6. The buckle plate 1 can be provided with a second bolt passing hole 7. The buckle plate 1 can be used to be installed on the door frame and can be arranged on the door plate corresponding to the bolt fixing plate 4. The first bolt passing hole 6 and the second bolt passing hole 7 can be used for the bolt 12 to pass through. The bolt fixing plate 4 can be provided with a magnetic sensor 2. The buckle plate 1 can be provided with a magnet 11. The magnetic sensor 2 and the magnet 11 can be arranged opposite to each other so that the magnetic sensor 2 can sense the magnetic field of the magnet 11. The material of the buckle plate 1 can include but is not limited to any one of the following: stainless steel, aluminum alloy, plastic. The magnet 11 can be fixed on the buckle plate 1 by clamping or bonding. The magnetic sensor 2 can be a Hall sensor. The advantage of using a Hall sensor is that the Hall sensor has a small size and a low cost, which can effectively reduce the production cost of the door lock. The magnetic sensor 2 can be electrically connected to a lock body control unit. The lock body control unit can be an integrated circuit module with a single-chip microcomputer as the core. The core of the integrated circuit module can also be other programmable logic controllers, which are not specifically limited here.

[0027] Optionally, the magnet 11 and the magnetic sensor 2 can be arranged at the same horizontal height. The purpose of this arrangement is to enable the magnetic sensor 2 to more accurately sense the magnetic field of the magnet 11.

[0028] Optionally, as shown in Figure 1 The magnetic sensor 2 can be fixed in the magnetic sensor fixing hole 5. The fixing method of the magnetic sensor 2 includes but is not limited to bonding and clamping, which are not specifically limited here. The purpose of fixing the magnetic sensor 2 in the magnetic sensor fixing hole 5 is to enable the magnetic sensor 2 to more accurately detect the magnetic field of the magnet 11 without any obstacles between the magnetic sensor 2 and the magnet 11 in the closed state.

[0029] Optionally, as shown in Figure 1As shown, the latch fixing plate 4 may be provided with multiple first-type fixing holes 9. The first-type fixing holes 9 can be used to fix the latch fixing plate 4 to the door. There may be two first-type fixing holes 9, which are located on both sides of the latch fixing plate 4, so that the latch fixing plate 4 is fixed more firmly and thus the latch fixing plate 4 will not easily loosen.

[0030] Optionally, such as Figure 1 As shown, the magnetic sensor 2 may include a sensor head 201, a connecting wire 202, and a plug 203. The sensor head 201 is used to sense the magnetic field of the magnet 11. The sensor head 201 and the plug 203 can be connected via the connecting wire 202. The connecting wire 202 is used for signal transmission between the sensor head 201 and the plug 203 and for supplying power to the sensor head 201.

[0031] Optionally, the lock body control unit may be provided with a socket. The plug 203 can be inserted into the socket. The socket is provided in the lock body control unit so that when the plug 203 is inserted into the socket, it can both supply power to the magnetic sensor 2 and realize information transmission between the magnetic sensor 2 and the lock body control unit.

[0032] Optionally, such as Figure 1 As shown, the aforementioned snap-on plate 1 may be provided with a magnet mounting hole 8 and a second type of fixing hole 10. The magnet mounting hole 8 can be used to install the aforementioned magnet 11. The purpose of providing the magnet mounting hole 8 is to ensure that when the aforementioned magnet 11 is installed on the aforementioned snap-on plate 1, the surface of the magnet 11 can be flush with the surface of the aforementioned snap-on plate 1, so as not to affect the opening and closing of the door. The aforementioned magnet mounting hole 8 can be correspondingly provided with the aforementioned magnetic sensor fixing hole 5, so that the aforementioned magnet 11 in the aforementioned magnet mounting hole 8 can correspond to the aforementioned magnetic sensor 2 in the aforementioned magnetic sensor fixing hole 5. The aforementioned second type of fixing hole 10 can be used to fix the aforementioned snap-on plate 1 to the door frame with screws. The aforementioned second type of fixing hole 10 can be a countersunk screw hole, so that when the aforementioned snap-on plate 1 is installed with countersunk screws, the aforementioned snap-on plate 1 can be installed stably, and the screws will not protrude from the outer surface of the aforementioned snap-on plate 1, so as not to affect the opening and closing of the door.

[0033] Optionally, the door lock can include mounting fittings. The mounting fittings can include first type mounting fittings and second type mounting fittings. The first type mounting fittings can be countersunk screws matched with the first type mounting holes, thereby fixing the bolt fixing plate 4 on the door panel, and the screws will not protrude from the surface of the bolt fixing plate 4. The second type mounting fittings can be countersunk screws matched with the second type fixing holes 10, thereby fixing the buckle plate 1 to the door frame, and the screws will not protrude from the surface of the buckle plate 1. The first type mounting fittings and the second type mounting fittings can both be screws, and can be different in size. It should be noted that the mounting fittings can also be other parts that can fix the bolt fixing plate 4 and the buckle plate 1. The use of screw mounting can make the bolt fixing plate 4 and the buckle plate 1 firmly installed and less likely to shift.

[0034] Optionally, the lock body control unit can be provided with a fault counter. The fault counter can be a mechanical fault counter or an electronic fault counter. The mechanical fault counter usually realizes counting through a mechanical linkage. When the door lock fails, for example, the bolt cannot be normally ejected or retracted, the lock core rotates smoothly, etc., each time the fault occurs, a mechanical structure will be triggered to make the counter number wheel rotate, recording the number of faults. For example, when the old-fashioned mechanical lock of the safe appears abnormal opening difficulty, a small mechanical counter next to it will increase by one. In the electronic door lock system, the sensor detects the working state of each component of the door lock. Taking the intelligent fingerprint door lock as an example, when the fingerprint recognition module, the motor-driven bolt module or the communication module fails, the corresponding fault signal will be transmitted to the control chip of the door lock. The software program in the control chip will process these fault signals, and increase the value of the fault counter variable by one. Moreover, these fault data can be stored in the internal memory of the door lock, which is convenient for subsequent query. In the daily use of the door lock, the door panel and the door frame will produce a certain degree of displacement with the increase of the use time, causing the position of the magnetic sensor 2 and the magnet 11 to deviate, thereby causing the magnetic sensor 2 to fail to accurately detect the change of the magnetic field strength of the magnet 11, resulting in errors in the detection of the door opening and closing state of the door lock. Adding the fault counter can record the number of errors of the magnetic sensor 2. When the number of errors exceeds a certain value, the lock body control unit can notify the user to correct the door lock through the sound module or the communication module.

[0035] The above various embodiments of the present disclosure have the following beneficial effects: through the door lock of some embodiments of the present disclosure, the detection accuracy of the door lock on the door opening and closing state can be improved. Specifically, the reason why the detection accuracy of the door lock on the door opening and closing state is poor is that the function of the door lock to detect the door opening and closing state mainly relies on the addition of a gyroscope sensor in the door lock panel, and when the user's door opening and closing action is slight, the gyroscope sensor cannot timely sense the movement of the door, and in addition, the positioning accuracy of the gyroscope sensor is not high, which may cause false positives, resulting in that the door lock cannot normally detect the opening and closing state of the door. Based on this, the door lock of some embodiments of the present disclosure includes a lock body, a lock tongue fixing plate and a buckle plate, wherein the lock body includes a lock tongue; the first lock tongue through hole is arranged on the lock tongue fixing plate; the second lock tongue through hole is arranged on the buckle plate; the buckle plate is used to be installed on the door frame and is correspondingly arranged with the lock tongue fixing plate; the magnetosensitive sensor is arranged on the lock tongue fixing plate; the magnet is arranged on the buckle plate; the magnetosensitive sensor and the magnet are oppositely arranged; the magnetosensitive sensor is electrically connected with the lock body control unit. Also because the magnetosensitive sensor can sense the change of the magnetic field strength of the magnet, whether the user's door opening and closing action is slight or not, the magnetosensitive sensor can sense the change of the magnetic field strength of the magnet. Thus, the accuracy of the function of the door lock to detect the door opening and closing state can be effectively improved.

[0036] Figure 2 is a schematic view of a partial structure of a door according to an embodiment of the present disclosure. Figure 2 The buckle plate 1, the lock tongue fixing plate 4.

[0037] In some embodiments, the door can include a door body and a door lock as described in Figure 1 corresponding embodiments.

[0038] The above embodiments of the present disclosure have the following beneficial effects: through the door of the embodiments of the present disclosure, the opening and closing state of the door can be automatically detected, and when the user forgets to lock the door after closing the door, the door can be automatically locked, better protecting the personal safety and property safety of the user. Specifically, the reason why the door cannot automatically detect the opening and closing state and automatically lock is that the lock installed on the ordinary door is a non-intelligent pure mechanical lock and does not have the functions of detecting the opening and closing state of the door and automatically locking. Based on this, the door of some embodiments of the present disclosure includes a door body and a door lock as described in Figure 1 corresponding embodiments. Thus, the door can automatically detect the opening and closing state of the door, and when the user forgets to lock the door after closing the door, the door can be automatically locked, better protecting the personal safety and property safety of the user.

[0039] The above description is merely exemplary of some of the many possible embodiments of the present disclosure and of the principles thereof. It is to be understood that those skilled in the art will be able to devise various embodiments of the present disclosure without departing from the scope of the present disclosure as disclosed in the above description and attached claims, and that the scope of the present disclosure is not limited to the specific technical features described above. For example, the technical features described above can be replaced with other technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) to form other technical solutions.
