DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0032] In some embodiments, such as Figures 1-5 shown, the present utility model provides a power supply induction lighting door lock, comprising:

[0033] An authentication unit;

[0034] A lock body 1, comprising a lock body housing 2 and a driving unit, a control unit and a switch unit arranged inside the lock body housing 2, wherein the driving unit, the control unit and the switch unit are connected in sequence, the driving unit is used to supply power to the control unit, the control unit is used to drive the switch unit, the driving unit comprises an electromagnetic coil 400 and a battery box 600, the electromagnetic coil 300 is located at the left bottom of the lock body housing 2, and the battery box 600 is located at the right bottom of the lock body housing 2;

[0035] A lock catch, comprising a lock catch housing 3, a power supply and a photoelectric induction module, the lock catch housing 3 is provided with a power supply and a photoelectric induction module inside, the power supply is connected to the photoelectric induction module, wherein the photoelectric induction module comprises an induction module and an LED lamp 520, the LED lamp 530 is installed outside the lock catch housing 3, the induction module is arranged inside the lock catch housing 3, and the induction module is parallel to the lock body 1; the power supply is a weak current positive and negative power supply 510, and the power supply is connected to the electromagnetic coil 400.

[0036] Specifically, Figures 1-2 The shown direction is a top view. The driving unit is used to supply power to the lock body 1. When the positive and negative power supply 510 of the lock catch 500 contacts the electromagnetic coil 300 of the lock body 1, the electromagnetic coil 300 is electrified and supplies power to the lock body 1 at the same time. The control unit is used to verify identity information, control the motor 210, etc. The switch unit 200 is responsible for the movement of the lock tongue 400 and is used to lock and unlock the lock. When the lock body 1 leaves the lock catch 500, after the photoelectric induction module 530 does not sense an obstacle, the control LED lamp 520 lights up to illuminate the rear space and provide lighting. When the lock body 1 contacts the lock catch 500, after the photoelectric induction module 530 senses an obstacle, the control LED is turned off to save power. And the positive and negative power supply 510 of the lock catch 500 contacts the electromagnetic coil 300, and the electromagnetic coil 300 supplies power to the lock, and at the same time, the identity verification device is connected to the lock body, so it also supplies power to the identity verification device for identifying and verifying identity information after the door lock is locked.

[0037] It can be understood that the purpose of the low-voltage power design is to reduce energy consumption and ensure that the system can be more energy-saving and environmentally friendly without affecting performance. At the same time, the low-voltage power design can also reduce the safety hazards caused by excessive electricity, ensuring the safety during the use of the lock. The LED light 520 is used to illuminate the rear space, which can improve safety to a certain extent. In a dark environment, the lighting function of the LED light 520 can help users see the situation of the rear space more clearly, avoiding operation errors. In addition, the electromagnetic coil 300 is arranged at the bottom of the lock body 1 to ensure more direct and efficient power transmission.

[0038] In some embodiments, as Figure 2 shown, the control unit includes: a panel, on which a central controller 110 and a comparator 130 are arranged. The central controller 110 is located in the upper right of the panel and is connected to the comparator 130;

[0039] Specifically, the receiver 120 is used to receive the identity information sent by the identity verification device, and the comparator 130 is used to check whether the identity information matches. When the identity information matches or does not match, the central controller 110 is used to send corresponding instructions. At the same time, the central controller 110 is also used to control the prompter 710 on the identity verification device. The prompter 710 can emit three different sounds to prompt the user about the current state of the door lock. When the identity information sent by the identity verification device matches, the central controller 110 sends an instruction to the prompter 710, and the prompter 710 emits an unlocking sound to prompt the user that the lock is currently open. When the identity information sent by the identity verification device does not match, the central controller 110 sends an instruction to the prompter 710, and the prompter 710 emits a non-matching sound to prompt the user. When the door lock is locked, the central controller 110 sends an instruction to the prompter 710, and the prompter 710 emits a locking sound to prompt the user that the lock is currently locked, reminding the user of the current door lock state and facilitating the user to make subsequent operations based on the sound prompt.

[0040] It can be understood that the receiver 120 and the comparator 130 ensure the efficiency and reliability of the identity verification process. When the user sends identity information through the identity verification device, the receiver 120 will accurately receive and transmit this information to the comparator 130. The comparator 130 is responsible for comparing the received identity information with the legally preset information in the system, which ensures security and reliability. In addition, the accuracy and speed of the identity information verification process are also guaranteed. The collaborative work between the receiver 120 and the comparator 130 enables the identity verification process to be completed within milliseconds, and the user does not need to wait for a long time, improving the user experience. At the same time, since the comparator 130 can accurately identify legal and illegal identity information, it can also effectively prevent unauthorized users from attempting to unlock the door, thus enhancing the security of the door lock.

[0041] In some embodiments, the control panel 100 further includes: a receiver 120;

[0042] The receiver 120 is connected to the authentication device; one end of the receiver 120 is connected to the authentication unit, and the other end is connected to the comparator 130; one end of the comparator 130 is connected to the receiver 120, and the other end is connected to the central controller 110.

[0043] In some embodiments, the authentication unit includes: a prompter and an identification module. The identification module is disposed in the middle of the verification housing 700, and the prompter is disposed on one side of the identification module.

[0044] Specifically, the prompter 710 is used to emit a sound to remind the user of the current door lock state. The prompter 710 is controlled by the central controller 110. The central controller 110 receives the instruction issued by the comparator 130 and makes different instructions for the prompter 710. When the identity information matches, the door lock opens, and the central controller 110 issues an unlocking sound instruction to the prompter 710. The prompter 710 emits an unlocking sound to remind the user of the current door lock state. When the identity information does not match, the central controller 110 issues a warning sound instruction to the prompter 710, and the prompter 710 emits a warning sound to remind the user of the current door lock state. When the door lock is closed, the central controller 110 issues a locking sound instruction to the indicator, and the prompter 710 emits a locking sound to remind the user that the current door lock has been closed.

[0045] It can be understood that the prompter 710 can emit a sound prompt after the user's operation or authentication to inform the user of the current door lock state. Through real-time sound feedback, the user can quickly understand the situation of the door lock, avoiding unnecessary waiting and guessing. At the same time, the sound prompt is a simple and intuitive feedback method. Especially for the elderly or users with visual impairments, the sound prompt is easier to understand than the visual prompt, and it also improves the user-friendliness. When the user tries to unlock the door, if the identity information does not match, the prompter 710 will emit a warning sound. This warning not only reminds the user that their operation is unsuccessful, but also can issue a warning when a potential security threat appears, playing a role in deterring lawbreakers and enhancing the security of the door lock. Moreover, the sound prompt can effectively reduce the occurrence of misoperations. When the authentication is successful or failed, the user can immediately confirm the door lock state through the sound prompt, reducing the inconvenience caused by misoperations or equipment failures.

[0046] In some embodiments, both the electromagnetic coil 300 and the battery box 600 are connected to the control panel 100.

[0047] Specifically, the drive unit of the lock body 1 includes: a battery and an electromagnetic coil 300. When the latch 500 can be normally powered on, the weak current positive and negative power supplies 510 on the latch 500 can supply power to the lock body 1 through the electromagnetic coil 300. However, when the latch 500 is powered off, the positive and negative power supplies 510 on the latch 500 lose their function. At this time, the battery can supply power to the door lock. These two power supply methods, the battery and the electromagnetic coil 300, can supply power simultaneously or switch to each other.

[0048] It can be understood that through the combination of the electromagnetic coil 300 and the battery, a stable power supply can be provided under different circumstances. When the positive and negative power supplies 510 on the latch 500 can work normally, power can be provided to the electromagnetic coil 300 through external power supply. This method is more energy-efficient, reduces the dependence on the battery, and extends the service life of the battery. When a fault occurs in the external power supply, the door lock will automatically switch to the battery power supply mode. The battery can be used as a backup power supply to ensure that the door lock can still work normally in an emergency, avoiding the situation where users cannot unlock the door due to power outage or power interruption. The redundant design of this dual power supply method significantly improves the reliability of the lock. Therefore, it is particularly important for a door lock with a dual power supply mode to cope with emergencies. In addition, in some security application scenarios, the reliability of power supply is crucial. The dual power supply method provides higher protection to ensure that the lock can work normally in various situations and will not affect safety due to power supply problems.

[0049] In some embodiments, heat dissipation holes 11 are provided around the electromagnetic coil 300.

[0050] Specifically, when the electromagnetic coil 300 is working, it will generate heat, and the heat dissipation holes 11 can effectively discharge the heat so that it will not concentrate inside the lock body 1. If it is in a high-temperature state for a long time, it will also shorten the service life of the components of the lock body 1.

[0051] It can be understood that temperature has a direct impact on the resistance value of the electromagnetic coil 300. A higher temperature will increase the resistance, thereby affecting the current and magnetic field strength of the coil. By effectively controlling the temperature through the heat dissipation holes 11, the resistance value of the electromagnetic coil 300 can be kept stable, so as to ensure that the magnetic field strength generated by the electromagnetic coil 300 remains within the optimal range, improving the working performance of the lock. Working at a high temperature for a long time will increase the failure rate of electronic components. By reducing the temperature through the heat dissipation holes 11, the overall failure rate of the lock can be significantly reduced, reducing the maintenance cost and user troubles caused by failures. In addition, the material of the electromagnetic coil 300 is prone to aging and degradation at high temperatures, and other electronic components (such as control modules, sensors, etc.) around the electromagnetic coil 300 will also be affected by temperature. The heat dissipation holes 11 not only help the coil dissipate heat, but also indirectly reduce the working temperature of other components, reducing the aging speed of these components and extending the service life of the entire device.

[0052] In some embodiments, the switch unit 200 includes: a motor 210, a gear 220, a latch moving module 230, and a latch 400. A gear 220 is provided at the front end of the motor 210. The gear 220 meshes with the latch moving module, and the latch moving module is connected to the latch 400.

[0053] Specifically, when the central controller 110 issues an instruction to the switch unit 200, the motor 210 drives the gear 220 to rotate. The gear 220 meshes with the latch moving module to control the displacement of the moving module. The latch 400 is connected to the latch moving module. When the module displaces, the latch 400 moves accordingly. By means of this device, the movement of the latch 400 can be effectively controlled to achieve the purpose of unlocking or locking.

[0054] It can be understood that the gear 220 meshing with the latch moving module ensures smooth power transmission during the transmission process, avoids errors caused by friction or sliding, and also ensures the long-term stable life of the switch unit 200, reduces the damage rate, and reduces the occurrence of situations where unlocking or locking cannot be achieved due to damage. Moreover, the gear 220 transmission device can effectively reduce the noise during operation. Compared with other types of mechanical transmissions, the gear 220 transmission has lower noise, especially when used in a quiet environment, it will not cause noise interference.

[0055] In some embodiments, a card slot 540 is provided on the latch 500, and the latch 400 is received in the card slot 540 to limit the degree of freedom of the latch 400.

[0056] In some embodiments, a shock absorption device is provided around the card slot 540.

[0057] In some embodiments, a drive switching device 140 is further provided on the panel.

[0058] When the door lock is in the closed state, when the identity verification device receives the identity information, it is transmitted to the comparator 130 for identity information comparison. When the identity information matches, the comparator 130 sends an instruction to the central controller 110. The central controller 110 controls the motor 210. The motor 210 drives the gear 220 to rotate, and the gear 220 drives the latch moving module 230 to displace, so that the latch 400 retracts. At the same time, the central controller 110 also sends an instruction to the reminder 710 to issue an unlocking sound prompt. When the lock body 1 disengages from the latch 500, the positive and negative power supplies 510 on the latch 500 disconnect the connection with the electromagnetic coil 300, and the switch unit 200 is powered off;

[0059] After the lock body 1 leaves the latch 500, the photoelectric induction module 530 controls the LED lamp 520 to light up for illuminating the rear space;

[0060] When the lock body 1 is attached to the lock catch 500 again, the positive and negative power supply 510 on the lock catch 500 contacts the electromagnetic coil 300, and the electromagnetic coil 300 is electrified to provide power for the lock body 1. At this time, the central controller 110 controls the motor 210, the motor 210 drives the gear 220 to rotate, and the gear 220 drives the lock tongue moving module 230 to displace, so that the lock tongue 400 extends. At the same time, when the photoelectric induction module 530 senses the attachment of the lock body 1, it controls the LED lamp 530 to turn off, saving power. The central controller 110 also sends an instruction to the reminder 710 to emit a locking sound;

[0061] When the door lock is in the closed state and the identity verification device receives the identity information, it is transmitted to the comparator 130 for identity information comparison. When the identity information does not match, the central controller 110 sends an instruction to the reminder 710 to emit a matching failure sound to indicate a matching failure.

[0062] The power supply and the battery can be used simultaneously or switched with each other.

[0063] To prevent the situation where the door lock cannot be used when there is a sudden power outage or a failure occurs in one of the power sources.
