Description

Technical Field

[0001] This application relates to the field of smart padlock technology, and in particular to a GPS smart logistics padlock. Background Technology

[0002] With economic development, the logistics industry is booming. The amount of losses due to theft and tampering of goods in the logistics sector each year is almost incalculable. Therefore, the logistics and transportation sector is paying increasing attention to the security of goods during transit. Ordinary mechanical locks are complex in structure, easily broken, and have low security and reliability. Their keys are also easily copied, posing a significant security risk to the property of companies and customers. At the same time, the development of the internet has brought challenges to logistics technology. To deliver goods to their destination quickly, accurately, and safely, more and more logistics companies are adopting electronic locks with GPS positioning capabilities to ensure the safety of their goods.

[0003] While existing GPS electronic locks possess simple electronic unlocking functions, their lock beam structures typically lack active anti-theft shearing mechanisms, failing to trigger alarms immediately when the lock body is subjected to violent damage. Furthermore, most of these GPS electronic locks lack integrated reliable network communication modules, preventing real-time reporting of lock status and abnormal events to the management platform. All of these factors limit the security effectiveness of existing GPS electronic locks in smart logistics scenarios. Summary of the Invention

[0004] The purpose of this application is to provide a GPS smart logistics padlock, which aims to improve the existing GPS electronic locks' lack of active anti-theft cutting mechanism and the absence of a reliable network communication module, thus limiting the security performance of existing GPS electronic locks in smart logistics scenarios.

[0005] To achieve this objective, this application provides a GPS smart logistics padlock, which includes a lock housing assembly, a lock beam, an unlocking and locking module, an anti-theft shearing module, a control module, a network communication module, and a GPS positioning module.

[0006] The lock housing assembly has two lock beam insertion holes on its surface that communicate with the internal space;

[0007] The locking beam includes a first end and a second end, the first end and the second end respectively extending into the internal space through a locking beam insertion hole;

[0008] The unlocking and locking module is installed in the internal space. The unlocking and locking module includes a locking pin and a power mechanism. The power mechanism is driven to the locking pin to drive the locking pin to make a movable locking connection with the first end and / or the second end under the unlocking and locking command of the control module.

[0009] The anti-theft cutting module includes an anti-theft cutting wire, which is built into the lock beam. The anti-theft cutting module is configured to trigger a theft cutting alarm signal by synchronously disconnecting the anti-theft cutting wire when the lock beam is cut while the GPS smart logistics padlock is locked.

[0010] The control module, the network communication module, and the GPS positioning module are respectively built into the lock housing assembly, and the control module is electrically connected to the power mechanism, the anti-theft cutting module, the network communication module, and the GPS positioning module.

[0011] Optionally, in some embodiments of this application, the anti-theft scissor module further includes a first power-on detection point and a second power-on detection point, wherein,

[0012] The first power-on detection point is configured to be directly or indirectly connected to one end of the anti-theft wire located at the first end when the GPS smart logistics padlock is in the locked state, so as to realize the power-on detection of the first end.

[0013] The second power-on detection point is configured to be directly or indirectly connected to one end of the anti-theft cutter wire located at the second end when the GPS smart logistics padlock is in the locked state, so as to realize the power-on detection of the second end.

[0014] Optionally, in some embodiments of this application, the internal space is provided with a first assembly area corresponding to one of the lock beam insertion holes, the first power-on detection point is provided in the first assembly area, and a contact ring and a lock beam plug are sequentially provided on the first power-on detection point. The first end is elastically mounted on the lock beam plug by a plug spring, so that when the GPS smart logistics padlock is in the locked state, one end of the anti-theft cutter wire located in the first end is electrically connected to the first power-on detection point in sequence through the lock beam plug and the contact ring.

[0015] Optionally, in some embodiments of this application, the internal space is provided with a second assembly area corresponding to another lock beam socket, the second power-on detection point is provided in the second assembly area, and a detection rod is elastically mounted on the second power-on detection point by a detection rod spring, so that when the GPS smart logistics padlock is in the locked state, one end of the anti-theft cutter wire located at the second end can be electrically connected to the second power-on detection point in sequence through the detection rod and the detection rod spring.

[0016] Optionally, in some embodiments of this application, the first end is provided with a first locking pin slot, and the second end is provided with a second locking pin slot;

[0017] The power mechanism includes a cam motor and a cam transmission component. The cam motor is connected to the locking pin via the cam transmission component to drive the locking pin to move linearly, thereby simultaneously engaging with the first locking pin slot and the second locking pin slot to achieve the movable locking connection.

[0018] Optionally, in some embodiments of this application, a limiting groove is provided on the periphery of the first end, and the GPS smart logistics padlock further includes a lock beam disassembly limiting module. The lock beam disassembly limiting module is installed in the internal space and is movable and limited in cooperation with the limiting groove.

[0019] Optionally, in some embodiments of this application, the lock beam disassembly limiting module includes a limiting card and a card spring. One end of the limiting card is rotatably assembled in the internal space, and the other end of the limiting card is elastically assembled in the internal space through the card spring. The other end of the limiting card is configured to be stuck in the limiting groove under the elastic force of the card spring.

[0020] The surface of the locking housing assembly is also provided with a disassembly hole that communicates with the internal space. The disassembly hole is configured to allow a columnar body of a preset size to extend into the internal space through the disassembly hole to apply an external force to the other end of the limiting card, so that the other end of the limiting card overcomes the elastic force of the card spring under the action of the external force and disengages from the limiting groove.

[0021] Optionally, in some embodiments of this application, the lock housing assembly includes an outer shell and a first inner shell having the internal space. The first inner shell is built into the outer shell, and one side wall of the first inner shell is fitted to the side wall of the outer shell, so that the two lock beam holes pass through the side wall of the outer shell and the side wall of the first inner shell in sequence and communicate with the internal space. The locking and unlocking module is installed in the internal space of the first inner shell.

[0022] Optionally, in some embodiments of this application, the locking housing assembly further includes a second inner housing, which is built into the outer housing and arranged side by side with the first inner housing;

[0023] The GPS smart logistics padlock also includes a power supply module, which is electrically connected to the unlocking and locking module, the anti-theft cutting module, the control module, and the network communication module. The power supply module is at least partially built into the second inner shell.

[0024] Optionally, in some embodiments of this application, the network communication module is a 4G communication module or a 5G communication module; and / or,

[0025] The GPS smart logistics padlock also includes a Bluetooth communication module, which is built into the lock housing assembly and electrically connected to the control module; and / or,

[0026] The anti-theft cutter module also includes a buzzer, which is built into the lock housing assembly. The anti-theft cutter module is also configured to respond to the theft cutter alarm signal at least by means of the buzzer.

[0027] The GPS smart logistics padlock provided in this application, through the aforementioned structural design, significantly enhances the physical anti-vandalism performance of the GPS smart logistics padlock. Firstly, its anti-theft cutting module, by embedding the anti-theft cutting wire within the lock beam and linking it with the control module, immediately triggers a theft cutting alarm signal when the lock beam is cut, enabling real-time monitoring and reporting of forced entry. Secondly, it integrates a network communication module, supporting remote control of locking and unlocking operations and real-time reporting of location information, lock status, and abnormal events (such as anti-theft cutting alarms) to the cloud-based management platform. Thus, this GPS smart logistics padlock compactly integrates electronic locking / unlocking, anti-theft cutting detection, network communication, and GPS positioning modules within the lock housing assembly. This compact structure facilitates installation and maintenance while simultaneously providing GPS positioning, padlock status networking, and anti-theft cutting functionality, ensuring the security performance of the GPS smart logistics padlock in smart logistics scenarios. It is evident that this technical solution can effectively address the shortcomings of existing GPS electronic locks, such as the lack of an active anti-theft and cutting mechanism and the absence of a reliable network communication module, which restricts the security performance of existing GPS electronic locks in smart logistics scenarios.

Detailed Implementation

[0041] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0043] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] In one implementation, such as Figures 1 to 3As shown in the figure, this application embodiment provides a GPS smart logistics padlock 1. The GPS smart logistics padlock 1 specifically includes a lock housing assembly 10, a lock beam 20, an unlocking / locking module 30, an anti-theft cutting module 40, a control module 50, a network communication module (not shown), and a GPS positioning module (not shown). The lock housing assembly 10 has two lock beam insertion holes 11 on its surface that communicate with the internal space. The lock beam 20 includes a first end 21 and a second end 22, which extend into the internal space through lock beam insertion holes 11. The unlocking / locking module 30 is installed in the internal space and includes a locking pin 31 and a power mechanism 32. The power mechanism 32 is driven to the locking pin 31 to drive the locking pin 31 to engage with the first end 21 and / or the second end 22 under the unlocking / locking command of the control module 50. The anti-theft cutting module 40 includes an anti-theft cutting wire 41, which is built into the lock beam 20. The anti-theft cutting module 40 is configured to trigger a theft alarm signal by synchronously disconnecting the anti-theft cutting wire 41 if the lock beam 20 is cut when the GPS smart logistics padlock 1 is in the locked state. The control module 50, the network communication module, and the GPS positioning module are respectively installed in the lock housing assembly 10, and the control module 50 is electrically connected to the power mechanism 32, the anti-theft cutting module 40, the network communication module, and the GPS positioning module.

[0045] It should be noted that the GPS smart logistics padlock 1 of this application embodiment is mainly applied to logistics scenarios with strict requirements for security and traceability, such as high-value goods transportation, cross-border logistics, shared warehousing, and cold chain pharmaceutical distribution, to achieve status monitoring and anti-theft protection of goods. The aforementioned locking beam 20 can be a conventional U-shaped locking beam 20 or a steel cable locking beam 20. The aforementioned locking pin 31 and the first end 21 and / or the second end 22 being connected by a movable latch specifically means that the locking pin 31 can be connected to only one end of the locking beam 20 (i.e., the first end 21 or the second end 22) by a conventional single-sided movable latch under the drive of the power mechanism 32, or it can be connected to both ends of the locking beam 20 (i.e., the first end 21 and the second end 22) by a double-sided movable latch under the drive of the power mechanism 32. Compared with the conventional single-sided movable latch connection, when it is connected by a double-sided movable latch, it can also form a multi-point cooperative locking structure to enhance the anti-pry and overall stability of this GPS smart logistics padlock 1. The aforementioned anti-theft cutting wire 41 extends in the same direction as the lock beam 20. When the GPS smart logistics padlock 1 is locked, the anti-theft cutting wire 41 is positioned to at least cover the portion of the lock beam 20 exposed outside the lock housing assembly 10 (i.e., the portion of the lock beam 20 exposed outside the lock housing assembly 10 is equipped with the anti-theft cutting wire 41) to ensure that the anti-theft cutting wire 41 can be disconnected synchronously when the lock beam 20 is cut.

[0046] Furthermore, the aforementioned control module 50 is mainly used to authenticate the user's identity using electronic information such as password, fingerprint, or electronic key, and then issue corresponding unlocking / locking commands to the power mechanism 32 to control the power mechanism 32 to perform corresponding unlocking / locking operations. Therefore, when this GPS smart logistics padlock 1 is specifically a combination lock structure, the control module 50 also includes at least a combination panel 51 disposed on the surface of the lock housing assembly 10, so that the user can input the corresponding password through the combination panel 51.

[0047] Furthermore, the GPS positioning module mentioned above can upload the precise location information obtained along with status data to a remote management platform, enabling 24 / 7 monitoring of the cargo's geographical location during logistics transportation. This greatly enhances the visibility and security of the transportation process, providing crucial data support for route optimization, abnormal stop alarms, and loss prevention.

[0048] In this way, the GPS smart logistics padlock 1 of this application embodiment, through the above-described structural configuration, on the one hand, its anti-theft cutting module 40, by embedding the anti-theft cutting wire 41 in the lock beam 20 and linking it with the control module 50, can immediately trigger a theft cutting alarm signal when the lock beam 20 is cut, realizing real-time monitoring and reporting of violent damage, thereby significantly improving the physical anti-vandalism performance of the GPS smart logistics padlock 1. On the other hand, it also integrates a network communication module, enabling it to support remote control of locking and unlocking operations, and can report location information, lock status, and abnormal events (such as anti-theft cutting alarm information) to the cloud management platform in real time. Thus, the GPS smart logistics padlock 1 can compactly integrate functional modules such as electronic locking and unlocking, anti-theft cutting detection, network communication, and GPS positioning into the lock housing assembly 10, making its structure compact and easy to install and maintain, while also realizing GPS positioning, padlock status networking, and anti-theft cutting functions, ensuring the security performance of the GPS smart logistics padlock 1 in smart logistics scenarios.

[0049] In some examples, such as Figures 1 to 3As shown, the anti-theft cutting module 40 also includes a first power-on detection point 42 and a second power-on detection point 43. The first power-on detection point 42 is configured to be directly or indirectly electrically connected to one end of the anti-theft cutting wire 41 located at the first end 21 when the GPS smart logistics padlock 1 is in the locked state, thereby detecting the power supply to the first end 21. The second power-on detection point 43 is configured to be directly or indirectly electrically connected to one end of the anti-theft cutting wire 41 located at the second end 22 when the GPS smart logistics padlock 1 is in the locked state, thereby detecting the power supply to the second end 22. Thus, by setting corresponding power-on detection points (i.e., the first power-on detection point 42 and the second power-on detection point 43) at both ends of the anti-theft cutting wire 41, the electrical connection integrity of the lock beam 20 in the locked state can be accurately and independently detected simultaneously at both ends of the lock beam 20, enabling rapid and accurate identification of theft incidents. When the GPS smart logistics padlock 1 is in the unlocked state, although neither the power-on detection at the first end 21 nor the power-on detection at the second end 22 detects any power, the anti-theft cutting module 40 will not determine that the lock has been cut and trigger the anti-theft cutting alarm signal because the lock is currently identified as unlocked. When the GPS smart logistics padlock 1 is in the locked state, it is considered to be in a normal locked state when both the power-on detection at the first end 21 and the power-on detection at the second end 22 detect power simultaneously. In this case, no alarm will be issued and the lock will not be identified as cut. However, when the lock beam 20 is cut or damaged, causing at least one of the power-on detections at the first end 21 and the second end 22 to fail to detect power, the anti-theft cutting module 40 will determine that the lock has been cut and trigger the anti-theft cutting alarm signal because the lock is still identified as locked.

[0050] In addition, this example also improves the accuracy of the anti-theft clipper alarm and the reliability of the system by setting up dual power-on detection points 42 and 43. Even if any power-on detection point fails, the detection effect of the anti-theft clipper can still be ensured by the other power-on detection point.

[0051] In some examples, such as Figure 3As shown, the internal space is provided with a first assembly area (not shown in the figure) corresponding to a lock beam insertion hole 11. A first power-on detection point 42 is located in the first assembly area, and a contact ring 44 and a lock beam plug 45 are sequentially arranged on the first power-on detection point 42. The first end 21 is elastically assembled to the lock beam plug 45 through a plug spring 46, so that when the GPS smart logistics padlock 1 is in the locked state, one end of the anti-theft cutter wire 41 located in the first end 21 is electrically connected to the first power-on detection point 42 through the lock beam plug 45 and the contact ring 44 in sequence. In this way, through the above structural arrangement, on the one hand, the first end 21 can be elastically assembled through the plug spring 46, so that when the GPS smart logistics padlock 1 switches from the locked state to the unlocked state, the lock beam 20 can be automatically lifted. On the other hand, by combining the assembly structure of the first power-on detection point 42 with the first end 21, the physical self-locking and automatic connection of electrical detection can be realized. That is, when the GPS smart logistics padlock 1 is in the locked state, the anti-theft cut wire 41 located at one end of the first end 21 can be well connected to the first power-on detection point 42.

[0052] In some examples, such as Figure 3 As shown, the internal space is provided with a second assembly area (not shown in the figure) corresponding to another lock beam insertion hole 11. A second power-on detection point 43 is located in the second assembly area, and a detection rod 47 is elastically mounted on the second power-on detection point 43 via a detection rod spring 48. When the GPS smart logistics padlock 1 is in the locked state, and the second end 22 is connected to the detection rod 47, one end of the anti-theft cutter wire 41 located in the second end 22 can be electrically connected to the second power-on detection point 43 in sequence through the detection rod 47 and the detection rod spring 48. In this way, through the above structural setting, the elastic detection rod 47 structure formed by the detection rod 47 and the detection rod spring 48 provides a buffer and automatic alignment function for the locking process of the lock beam 20 of the GPS smart logistics padlock 1, so as to ensure that the electrical connection can be reliably and stably established when the second end 22 is inserted. That is, when the GPS smart logistics padlock 1 is in the locked state, the indirect electrical connection between the one end of the anti-theft cutter wire 41 located in the second end 22 and the second power-on detection point 43 can be well realized. In addition, the elastic contact formed by the structure of the elastic detection rod 47 can effectively reduce the risk of poor contact caused by insertion and removal wear or vibration, ensuring the continuous accuracy of anti-theft shear detection.

[0053] It should be noted that, in order to ensure a more stable and effective connection between the second end 22 and the detection rod 47 when the GPS smart logistics padlock 1 is in the locked state, a insertion groove may be recessed on the end face of the second end 22. When the GPS smart logistics padlock 1 is in the locked state, the detection rod 47 can be inserted into the insertion groove and then abut against one end of the anti-theft wire 41 located in the second end 22.

[0054] In some examples, the anti-theft cutter module 40 in this example also includes a buzzer (not shown), which is built into the lock housing assembly 10. The anti-theft cutter module 40 is also configured to respond to the theft cutter alarm signal at least through the buzzer. Thus, by means of the built-in buzzer, an on-site audible and visual alarm (if the buzzer has an indicator light function) or a high-intensity sound can be immediately issued when the lock beam 20 is cut, effectively deterring destructive behavior and promptly alerting nearby personnel. This local alarm mechanism serves as an important supplement to network reporting, ensuring that basic on-site protection and warning capabilities are still available when network signals are temporarily interrupted.

[0055] In some examples, such as Figures 2 to 7 As shown, the first end 21 is provided with a first locking pin slot 211, and the second end 22 is provided with a second locking pin slot 221. The power mechanism 32 includes a cam motor 321 and a cam transmission component 322. The cam motor 321 is connected to the locking pin 31 through the cam transmission component 322 to drive the locking pin 31 to move linearly, so as to simultaneously engage with both the first locking pin slot 211 and the second locking pin slot 221 to achieve a movable locking connection. In this way, with the above structural configuration, the locking pin 31 can be driven by a single power source (i.e., the cam motor 321) to simultaneously engage with both ends of the lock beam 20 (i.e., the first end 21 and the second end 22), thereby achieving efficient and synchronous dual-point locking, which significantly enhances the anti-pry and anti-torsion capabilities of this GPS smart logistics padlock 1. In addition, the cam drive 322 converts the rotational motion of the cam motor 321 into precise linear motion, which can ensure the reliability and consistency of the insertion and removal action of the locking pin 31. Moreover, this structure not only simplifies the drive mechanism, but also improves the response speed of the locking action and the overall structural strength.

[0056] It should be noted that, in order to better enable the locking pin 31 to simultaneously engage with both the first locking pin slot 211 and the second locking pin slot 221 when it moves along one side, an arc-shaped notch 311 is provided at the end of the locking pin 31 that is connected to the second end 22 of the locking beam 20, allowing the second end 22 to pass through. Thus, when the other end of the locking pin 31 engages with the first locking pin slot 211, one side wall of the arc-shaped notch 311 can simultaneously engage with the second locking pin slot 221. To better facilitate the installation and fixation of the various components of this locking and unlocking module 30, the locking and unlocking module 30 in this example also includes a module bracket 33. Furthermore, the cam transmission component 322 in this example may specifically include a cam body 3221 and a cam transmission block 3222. After the cam transmission block 3222 is fastened to the locking pin 31, it is elastically mounted on the module bracket 33 by the transmission component spring 34. The cam body 3221 is fixed on the motor shaft of the cam motor 321 and is movably engaged with the cam transmission groove 3223 recessed on the cam transmission block 3222. In this way, when the motor shaft of the cam motor 321 drives the cam body 3221 to rotate, it drives the cam transmission block 3222 and the locking pin 31 to perform corresponding linear movements to complete the corresponding locking and unlocking actions.

[0057] In some examples, such as Figure 2 , Figures 8 to 10 As shown, a limiting groove 212 is provided on the periphery of the first end 21. The GPS smart logistics padlock 1 also includes a lock beam 20 disassembly limiting module, which is installed in the internal space and engages with the limiting groove 212 for movable limiting. Thus, through the movable limiting engagement between the lock beam 20 disassembly limiting module and the limiting groove 212 on the first end 21 of the lock beam 20, the GPS smart logistics padlock 1 can restrict the lock beam 20 even when it is in the unlocked state, preventing it from completely detaching from the internal space of the lock housing assembly 10, thereby effectively preventing the lock beam 20 from being accidentally lost during transportation or when not in use. Furthermore, the movable limiting engagement design between the lock beam 20 disassembly limiting module and the limiting groove 212 also allows the limiting engagement to be released when the lock beam 20 needs to be replaced, realizing the detachable design of the lock beam 20. This allows the GPS smart logistics padlock 1 to simultaneously support the replaceable design of both U-shaped lock beams 20 and steel cable lock beams 20.

[0058] In some examples, such as Figure 2 , Figures 8 to 10As shown, the locking beam 20 disassembly limiting module includes a limiting card 61 and a card spring 62. One end of the limiting card 61 is rotatably mounted in the internal space, and the other end of the limiting card 61 is elastically mounted in the internal space through the card spring 62. The other end of the limiting card 61 is configured to be engaged in the limiting groove 212 under the elastic force of the card spring 62. The surface of the lock housing assembly 10 is also provided with a disassembly hole 15 communicating with the internal space. The disassembly hole 15 is configured to allow a columnar body of a preset size to extend into the internal space through the disassembly hole 15 to apply external force to the other end of the limiting card 61, so that the other end of the limiting card 61 overcomes the elastic force of the card spring 62 under the action of the external force and disengages from the limiting groove 212. Thus, through the above structural design, the limiting card 61 loaded by the spring-loaded card plate cooperates with the limiting groove 212 to realize the function of limiting the movement of the lock beam 20 by the lock beam 20 disassembly limiting module. This effectively prevents the lock beam 20 from being accidentally lost during transportation or when not in use. Furthermore, when the lock beam 20 needs to be replaced, it allows for easy and quick release of the corresponding limiting mechanism by applying external force through the disassembly hole 15 using a special tool (such as a toothpick or other cylindrical object), thereby enabling the disassembly and replacement of the lock beam 20. In addition, this structural design of the lock beam 20 disassembly limiting module not only ensures that the lock beam 20 is not easily accidentally dislodged during daily use, but also provides convenient disassembly for authorized maintenance or recycling, balancing safety and ease of operation.

[0059] In some examples, such as Figure 1 and Figure 2 As shown, the lock housing assembly 10 includes an outer shell 12 and a first inner shell 13 with an internal space. The first inner shell 13 is built into the outer shell 12, and one side wall of the first inner shell 13 is fitted to the side wall of the outer shell 12, so that the two lock beam insertion holes 11 pass through the side wall of the outer shell 12 and the side wall of the first inner shell 13 in sequence, and communicate with the internal space. The unlocking and locking module 30 is installed in the internal space of the first inner shell 13. In this way, through the above structural arrangement, the core precision components of this GPS smart logistics padlock 1 (such as the unlocking and locking module 30) are provided with more robust physical isolation and protection through the double-layer nested structure of the outer shell 12 and the first inner shell 13. In addition, the fitted arrangement of the first inner shell 13 and the outer shell 12 ensures the precise alignment of the lock beam insertion holes 11 and the structural sealing, so as to effectively improve the overall dustproof, waterproof and impact resistance of the lock. At the same time, this layered design also takes into account the external durability and the stable operation of the internal modules, which facilitates assembly and maintenance.

[0060] It should be noted that the first inner shell 13 in this example can be a metal shell. In this way, by using metal material as the first inner shell 13, a more robust physical barrier is provided for the core precision components of this GPS smart logistics padlock 1 (such as the unlocking and closing module 30). That is, the metal shell can further effectively resist external violent impacts and illegal disassembly, significantly enhancing the security of key components such as the unlocking and closing module 30.

[0061] In some examples, such as Figure 1 and Figure 2 As shown, the lock housing assembly 10 also includes a second inner housing 14, which is built into the outer housing 12 and arranged side by side with the first inner housing 13. The GPS smart logistics padlock 1 also includes a power supply module, which is electrically connected to the unlocking / locking module 30, the anti-theft cutting module 40, the control module 50, and the network communication module. The power supply module is at least partially built into the second inner housing 14. Thus, by adding a separate second inner housing 14 to accommodate the power supply module, physical isolation and functional partitioning of the power supply (i.e., the power supply module) from the core control and drive modules are achieved. At the same time, this side-by-side layout optimizes the use of internal space and facilitates the independent installation, maintenance, and heat dissipation of each module. In addition, this example, through the separate second inner housing 14, can also form a corresponding partition design in the internal space of the outer housing 12, which can effectively reduce the impact of power supply (i.e., power supply module) interference on precision electronic components while improving the overall structural security and reliability.

[0062] It should be noted that the power supply module in this example is mainly used to power the various electrical components within the GPS smart logistics padlock 1, including but not limited to the locking / unlocking module 30, the anti-theft cutter module 40, the control module 50, and the network communication module. Furthermore, the power supply module in this example may specifically include a battery storage module and a solar power module and a wired power module electrically connected to the battery storage module. The solar power module includes a solar panel 71 mounted on the surface of the outer casing 12, and the wired power module includes a charging interface 72 mounted on the surface of the outer casing 12. Thus, by combining solar charging, wired charging, and battery energy storage, the GPS smart logistics padlock 1 constructs a multi-complementary power supply system, greatly extending the continuous working time of the GPS smart logistics padlock 1 in the field or in environments without a fixed power source. In addition, the solar panel 71 achieves self-collection of energy, and the wired interface ensures rapid power replenishment; the two work together to ensure the reliability and continuity of power supply, enabling the GPS smart logistics padlock 1 to meet the stringent power supply requirements of long-term outdoor logistics transportation.

[0063] In some examples, the network communication module in this example can specifically be a 4G communication module or a 5G communication module. Thus, this GPS smart logistics padlock 1, by employing a 4G / 5G communication module for network communication, can provide a high-speed, wide-coverage mobile network connection, ensuring that lock status, location, and alarm information can be reported to the remote management platform in real time and reliably. This meets the needs of modern logistics for high-efficiency tracking and monitoring throughout the entire process, and is especially suitable for continuous data transmission in cross-border transportation or mobile environments.

[0064] In some examples, the GPS smart logistics padlock 1 in this example also includes a Bluetooth communication module (not shown), which is built into the lock housing assembly 10 and electrically connected to the control module 50. Thus, by further integrating the Bluetooth communication module, the GPS smart logistics padlock 1 provides convenient near-field wireless communication capabilities, allowing authorized personnel to quickly perform operations such as unlocking, status inquiries, or parameter configurations at close range using smartphones or other devices. Furthermore, Bluetooth connectivity can serve as an effective supplement and backup channel for remote network control, significantly improving the flexibility and operational efficiency of the GPS smart logistics padlock 1 in scenarios with poor network signals or where convenient on-site management is required.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
