Description

Technical Field

[0001] The utility model relates to the technical field of electronic padlocks, in particular to a lock structure and an intelligent padlock. Background Art

[0002] With the development and application of Internet of Things technology, the application prospects of smart padlocks in personal, commercial and industrial fields are becoming increasingly broad. Smart padlocks not only provide higher security, but also greatly improve the convenience and management efficiency through remote control, status monitoring and data logging functions.

[0003] Smart padlocks generally require batteries. Currently, smart padlocks on the market generally use NB-Iot or 4G remote communication, plus other near-end communication modes such as Bluetooth, fingerprint or NFC to unlock. However, because the padlock design cannot be powered by a charger, designers generally use built-in batteries. In order to extend battery life, they tend to use rechargeable batteries, which can be charged to unlock when power is insufficient.

[0004] However, this design makes it impossible for maintenance personnel to charge the padlocks in batches at the same time when the locks are close to running out of power because the charging time is 1 to 2 hours. In addition, when the cover is opened to change the lock, the background cannot distinguish whether it is maintenance to change the battery or the cover is opened by an outsider with malicious intentions, resulting in a reduction in the security of the smart padlock. Utility Model Content

[0005] The main purpose of the utility model is to provide a lock structure and an intelligent padlock, aiming to improve the battery replacement efficiency and safety performance of the intelligent padlock.

[0034] The utility model provides a lock structure 100.

[0035] See also Figure 1 and Figure 2 In one embodiment, the lock structure 100 includes a lock body 1, a sealing cover 2, a sensing module and a transmission module. A first installation slot 11 for installing a battery 200 is formed inside the lock body 1, and an opening that passes through the first installation slot 11 is opened on one side of the lock body 1; the sealing cover 2 is covered on the opening to seal the first installation slot 11; the sensing module is accommodated in the first installation slot 11, and the sensing module includes a detection element and a circuit board electrically connected to the detection element. The detection element is used to detect whether a battery 200 is installed in the first installation slot 11 and output a corresponding detection signal; the transmission module is electrically connected to the sensing module, and is used to remotely output a corresponding alarm signal to the monitoring host according to the detection signal.

[0036] The lock structure 100 provided by the present invention integrates a sealing cover 2, a sensing module and a transmission module in the lock body 1. On the one hand, by designing an opening on the lock body 1 and equipping it with a sealing cover 2, a structure is designed that is convenient for quickly replacing the battery 200. When the battery 200 is low on power, the operation and maintenance personnel can quickly open the sealing cover 2 and replace the battery 200 without waiting for 1 to 2 hours of charging time, thereby improving the operation and maintenance efficiency, saving the padlock downtime caused by charging the battery 200, and ensuring the continuous operation of the smart padlock; on the other hand, the addition of the sensing module enables the padlock to detect whether the battery 200 is correctly installed, and send an alarm signal to the monitoring host through the transmission module when the battery 200 is missing. In this way, the background system can distinguish whether it is a normal replacement of the battery 200 or an illegal act of destruction, thereby improving the security of the smart padlock. The integration of the transmission module enables the padlock to remotely transmit status information, such as the installation status or safety status of the battery 200. When the battery 200 is illegally removed, the monitoring host can immediately receive an alarm through the cooperation of the sensing module and the transmission module, allowing the operation and maintenance personnel to respond in time. In this way, the security status of the padlock can be effectively monitored to prevent unauthorized destruction.

[0037] It is understandable that a detection component for detecting the capacitance of the battery 200 can also be provided in the lock body 1. The detection component for detecting the capacitance of the battery 200 can help the system monitor the remaining power of the battery 200, thereby uploading the information to the monitoring host when the power is low to remind the operation and maintenance personnel to replace the battery 200.

[0038] In one embodiment, a first sealing groove 12 is defined on one side of the lock body 1, and a first mounting groove 11 is defined on the bottom wall of the first sealing groove 12. A sealing cover 2 is received within the first sealing groove 12 to seal the first mounting groove 11. Since the sealing cover 2 is located within the first sealing groove 12, maintenance personnel can easily open the sealing cover 2 and directly access the first mounting groove 11 to replace the battery 200 without requiring complex procedures. Furthermore, the design of the sealing cover 2 effectively protects the battery 200 and internal circuitry from external environmental influences, such as moisture and dust, thereby improving the environmental adaptability and reliability of the smart padlock and extending its overall service life.

[0039] In one embodiment, a second sealing groove 13 is defined in the bottom wall of the first sealing groove 12, and a first mounting groove 11 is defined in the bottom wall of the second sealing groove 13. The lock structure 100 also includes a battery cover 3, which is accommodated within the first sealing groove 12 to seal the first mounting groove 11. By defining the second sealing groove 13 within the first sealing groove 12 and the first mounting groove 11 at its bottom, a double-layer sealing protection is achieved, greatly improving the waterproof and dustproof capabilities of the battery 200 area. The design of the battery cover 3 makes battery 200 replacement simple and quick, while maintaining a certain degree of safety, as the battery cover 3 must be opened before accessing the battery 200. The double-layer sealing groove design increases structural stability and reduces the risk of battery 200 displacement due to external impact or vibration.

[0040] In one embodiment, the bottom wall of the second sealing groove 13 further defines a locking hole 14; the battery cover 3 defines a connecting through-hole 31 corresponding to the locking hole 14; and the lock structure 100 further includes a locking member, the locking end of which is inserted into the connecting through-hole 31 and locked within the locking hole 14. By securing the battery cover 3 within the locking hole 14 using the locking member, the area surrounding the battery 200 is effectively sealed, preventing the ingress of moisture and dust. Furthermore, the use of the locking member makes it difficult to easily open the battery cover 3, thereby enhancing the overall security of the lock. When the battery 200 needs to be replaced, the battery cover 3 can be easily opened by unlocking the locking member, facilitating maintenance and replacement of the battery 200.

[0041] In one embodiment, the locking member is a locking screw, and the locking hole 14 is a threaded hole. The combination of the locking screw and the threaded hole makes the fixing and removal of the battery cover 3 simple and quick. The operation can be completed using only a suitable screwdriver.

[0042] In one embodiment, the lock structure 100 further includes an alarm module, which includes a voice chip and a speaker electrically connected to the voice chip. The voice chip is electrically connected to the sensing module, and the speaker is configured to emit an alarm sound based on a detection signal. When the sensing module detects an abnormal situation (such as an illegal unlocking attempt or a low battery 200), it sends a detection signal to the voice chip, which then emits an alarm sound through the speaker to alert the user or nearby people. Of course, in addition to the alarm sound, the speaker can also be used to emit other prompt sounds, such as audio feedback indicating that the lock has been successfully locked or unlocked. Through different audio signals, the user can intuitively understand the status of the lock, such as whether it has been successfully locked or unlocked.

[0043] In one embodiment, a second mounting slot is formed within the lock body 1; the alarm module is accommodated in the second mounting slot. A sound hole 15 is also formed in the bottom wall of the first sealing slot 12, communicating with the second mounting slot. Sound hole 15 ensures that the alarm sound or voice prompt can be clearly transmitted from the interior of the lock to the outside, improving the visibility or audibility of the alarm.

[0044] In one embodiment, the transmission module is a wireless network module and / or a SIM card communication module. The wireless network module generally refers to a Wi-Fi module, which allows the lock to connect to a home or business wireless network. The wireless network module can perform functions such as remotely controlling the lock, receiving instructions from smart devices, and sending status updates. Its advantages are fast transmission speeds and wide coverage, especially in indoor environments. The SIM card communication module allows the lock to communicate via a mobile network (such as a 2G, 3G, 4G, or 5G network). By inserting a SIM card, the lock can also communicate remotely in areas without Wi-Fi coverage. Its advantage is that as long as there is mobile network coverage, the lock can communicate anywhere, which is suitable for application scenarios that require wide geographical coverage.

[0045] In one embodiment, the detection element is a photosensor. The working principle of the photosensor is based on the photosensor's response to light intensity. When the battery 200 is correctly installed, the battery will block the light on the photosensor, causing the light intensity received by the sensor to decrease. After the photosensor detects the change in light intensity, it will send a signal to the transmission module to indicate that the battery 200 is properly installed. If the battery 200 is not properly installed, the light will not be blocked, and the photosensor will not detect the expected light change, thereby notifying the user that the battery is not properly installed. Of course, the photosensor can also have other functions simultaneously or independently. For example, in one embodiment, when the battery cover 3 and the sealing cover 2 remain closed, the photosensor is in a relatively stable lighting environment. Once the battery cover 3 and the sealing cover 2 are illegally opened, external light will immediately illuminate the photosensor, causing the sensor output signal to change. After receiving this change signal, the microprocessor of the smart lock can quickly respond. In another embodiment, the photosensor can also have the function of detecting violent unlocking. When the lock body 1 is damaged by external force, resulting in damage to the structural integrity, and light enters the lock body 1, the photosensor will immediately sense the change in light and output a detection signal, which in turn outputs an alarm signal to the monitoring host through the transmission module. Therefore, the photosensor can not only monitor the battery status, the battery cover 3 and the sealing cover 2 under normal circumstances, but also issue an alarm in time when the lock body 1 is subjected to violent damage, thereby providing multiple security guarantees for the smart lock. In other embodiments, the detection element can also be a magnetic sensor or other displacement sensor.

[0046] The present invention also provides a smart padlock, which includes a lock structure 100. The specific structure of the lock structure 100 refers to the above embodiment. Since the smart padlock adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.
