Description

Technical Field

[0001] The present invention belongs to the technical field of logistics locks, and in particular relates to a waterproof logistics electronic lock. Background Art

[0002] The electronic logistics lock is an innovative locking device designed to ensure the safety and efficiency of cargo transportation. It integrates modern communication technology to monitor cargo throughout its journey, providing comprehensive cargo security for shippers.

[0003] Currently, large-module logistics electronic locks are used outdoors, in complex and variable environments. The housing design of existing logistics electronic locks often houses the mechanical and electronic modules within a single compartment, resulting in poor water resistance. Over time, the lock cord can wear out, allowing rainwater to flow into the compartment along the cord, short-circuiting and damaging the circuit boards. Furthermore, since the mechanical and electronic components of a logistics electronic lock are housed in the same compartment, the motor generates high currents and strong electromagnetic fields, creating a strong source of interference. The close proximity of the motor and electronic module can interfere with the electronic communication module, causing unstable communication signals. Furthermore, when large-module logistics locks are used outdoors, a high level of wind, sand, and dust can enter the mechanical module through the lock cord. The presence of the electronic module prevents the mechanical module from being cleaned. Over time, this can cause the logistics lock to become stuck, leading to mechanical failure.

[0004] Therefore, in view of the problems of poor waterproofness, high failure rate and unstable signal in the current logistics electronic locks, a more reasonable technical solution needs to be proposed to effectively solve the existing technical problems. Summary of the Invention

[0008] In one possible design, a position detection device is provided in the lock hole for detecting position information of the lock rod in the lock hole; an angle detection device is provided on the output shaft for detecting rotation angle information of the output shaft; The position detection device and the angle detection device are both communicatively connected to the electronic module, and the electronic module is communicatively connected to the driver.

[0009] In a possible design, the locking groove is configured as an annular groove; the groove wall of the locking groove is configured as a curved surface, and the end surface of the locking tongue is configured as a spherical surface adapted to the locking groove.

[0010] In one possible design, a partition is provided in the shell, which separates the shell into a mechanical compartment and an electronic compartment, wherein both ends of the partition are formed into inclined guide surfaces, and the guide surfaces are abutted against the drainage hole to guide the liquid to flow along the guide surfaces into the drainage hole.

[0011] In a possible design, the guide surface is formed as a plane or a curved surface.

[0012] In a possible design, the drainage hole is formed as a curved channel.

[0013] In one possible design, the locking cable is fixedly connected to the housing via a locking cylinder; The lock cylinder is provided with a slot, the mechanical compartment is provided with a limit plate, and the limit plate is provided with a limit slot adapted to the slot; wherein the size of the limit slot is set so that the lock cylinder can only be fixed in the limit slot in the horizontal direction; the top wall and bottom wall of the slot respectively abut against the limit plate to limit the freedom of the lock cylinder in the vertical direction; The side walls of the clamping slot are configured as a first plane, and the fitting surface between the limiting slot and the first plane is configured as a second plane.

After the logistics lock is used for a long time outdoors in a harsh environment, mud and sand will enter the logistics lock from the lock rope position.

At the same time, in the case of mud and sand, the mud and sand can also be flushed out of the mechanical compartment by rainwater, thereby playing a certain protective role for the structure inside the mechanical compartment, and preventing mud and sand from getting stuck in the mechanical compartment and affecting the mechanical structure.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that although the description of these embodiments is intended to help understand the present invention, it does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are merely intended to describe exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0021] According to the first aspect of the present invention, a waterproof electronic logistics lock is provided. Figures 1 to 5 One specific embodiment is shown.

[0022] See Figures 1 to 5 As shown, the waterproof logistics electronic lock includes an electronic module 1, a mechanical module 2 for locking a locking rod 41, a shell 3 and a locking rope 4; a mechanical compartment 31 and a sealed electronic compartment 32 are provided on the shell 3, and the electronic module 1 is provided in the electronic compartment 32; a mechanical module 2 is provided in the mechanical compartment 31, one end of the locking rope 4 is fixedly connected to the shell 3, and the other end is provided with a locking rod 41 for connecting to the mechanical module 2; wherein, a drainage hole 33 connected to the outside is provided in the mechanical compartment 31.

[0023] Through the above technical solution, based on the separate design of the mechanical compartment 31 and the electronic compartment 32, because the electronic compartment 32 is completely sealed, when water enters the mechanical compartment 31, the water will not penetrate into the electronic compartment 32, and therefore will not affect the electronic module 1 in the electronic compartment 32. After the logistics lock is used for a long time outdoors in a harsh environment, mud and sand will enter the logistics lock through the lock rope 4. Because the mechanical compartment 31 allows water to enter, and based on the provision of the drainage hole 33, the mechanical compartment can be disassembled and filled with water, thereby flushing mud, dirt, and other fluids out of the mechanical compartment 31. When it rains, rainwater will also flow out of the drainage hole 33. At the same time, if there is mud and sand, the rainwater can also flush the mud and sand out of the mechanical compartment, thereby providing a certain degree of protection for the structure within the mechanical compartment 31, preventing mud and sand from getting stuck in the mechanical compartment 31 and affecting the mechanical structure. This waterproof logistics electronic lock has excellent waterproof performance and is easy to maintain, making it very suitable for use in harsh outdoor environments.

[0024] One end of the lock cord 4 is fixed to the housing 3, and the other end is connected to the lock rod 41, which can achieve flexible locking. It should be noted that the lock cord has a certain toughness and can be bent; at the same time, the lock cord also has a certain shear strength, which is difficult to cut under normal circumstances and requires special equipment.

[0025] Because the mechanical compartment 31 is separated from the electronic compartment 32, the electronic compartment 32 is sealed to prevent moisture intrusion, thereby ensuring the safe operation of the electronic module 1. The mechanical compartment 31 is equipped with a drainage hole 33 to facilitate cleaning, prevent mud and sand from getting stuck, and improve the durability of the lock. In actual application, different housing materials can be selected as needed to ensure that the lock can maintain normal operation in harsh environments.

[0026] In one embodiment provided herein, a partition 34 is provided within the housing 3. This partition 34 separates the housing 3 into a mechanical compartment 31 and an electronic compartment 32, ensuring physical isolation between the two. The ends of the partition 34 are formed into inclined guide surfaces 35, which guide liquid (such as rainwater, cleaning water, etc.) along the guide surfaces 35. The guide surfaces 35 abut against the drain holes 33, ensuring that the liquid can flow smoothly into the drain holes 33. This guide surface 35 guides the liquid along the guide surfaces 35 into the drain holes 33, promptly draining mud or water from the mechanical compartment 31 and preventing water accumulation and stains. This not only enhances the waterproof performance of the logistics electronic lock, but also improves its ease of cleaning and maintenance. During long-term outdoor use, even in harsh environments such as mud, sand, and rain, the lock can maintain good working condition, ensuring logistics safety.

[0027] Partition 34 features cable holes for routing cables, allowing the mechanical module 2 and detection devices (position detection device 51 and angle detection device 52) to connect to the electronic module 1 via corresponding cables. This allows each electrical component to communicate with the electronic module 1 through a wired connection, which helps ensure signal stability. Glue is applied between the cable holes and the cables to create a seal, ensuring the electronic logistics lock's waterproof performance.

[0028] In the present disclosure, the guide surface 35 is formed as a plane or a curved surface, so that the liquid can be guided to flow along its surface and eventually drain into the drainage hole 33. This structural design helps to keep the mechanical compartment 31 clean and dry, and prevent mechanical failures caused by mud, dirt, etc.

[0029] In one embodiment, the guide surface 35 is configured as a plane, thereby providing a simple and effective flow path, ensuring the stability of liquid flow, and allowing the liquid to flow quickly and directly to the drainage hole 33. In addition, the plane structure is easy to manufacture, which is beneficial to reducing production costs.

[0030] In another embodiment, the guide surface 35 is configured as a curved surface, which allows the liquid to flow more smoothly toward the drainage hole 33. The curved surface design can reduce the flow resistance of the liquid, improve the drainage efficiency, and may reduce the retention of liquid on the guide surface 35 to a certain extent.

[0031] In this regard, those skilled in the art may select any of the above implementation schemes based on the technical concept of the present disclosure.

[0032] In an exemplary embodiment provided herein, the drainage hole 33 is formed as a curved channel. Compared to a straight hole design, the curved channel makes it more difficult for liquid to enter, effectively preventing external liquids (such as rainwater, cleaning water, etc.) from directly invading the interior of the mechanical compartment 31, thereby improving the lock's waterproof performance. Furthermore, the curved channel can better guide liquid along its path, ensuring that the liquid can be smoothly discharged from the mechanical compartment 31. Thus, this structural design reduces the retention of liquid in the channel, keeping the mechanical compartment 31 clean and dry. Furthermore, the curved channel design increases the structural strength of the housing 3 to a certain extent, making the lock more durable and suitable for various harsh environments.

[0033] In one embodiment provided by the present disclosure, the mechanical module 2 includes a lock core 21, a lock tongue 22, a spring 23, a cam 24, and a driver 25. Specifically, the lock core 21 is provided with a lock hole 211, a cam hole 212, and a lock tongue hole 213. The lock hole 211 is vertically arranged, and the lock rod 41 is movably arranged in the lock hole 211, and the lock rod 41 is provided with a lock groove 411 adapted to the lock tongue 22; the cam hole 212 is arranged parallel to the lock hole 211, the cam 24 is embedded in the cam hole 212, and the output shaft of the driver 25 is fixedly connected to the cam 24; the lock tongue hole 213 is horizontally arranged, and its two ends are respectively connected to the lock hole 211 and the cam hole 212, the lock tongue 22 is embedded in the lock tongue hole 213, and one end of the spring 23 is connected to the lock core 21, and the other end is connected to the lock tongue 22.

[0034] Among them, when the driver 25 rotates to a first angle, the large diameter end of the cam 24 abuts against the lock tongue 22 and pushes the lock tongue 22 to move toward the lock rod 41, so that the lock tongue 22 is embedded in the lock groove 411, and the lock core 21 locks the lock rod 41; when the driver 25 rotates to a second angle, the large diameter end of the cam 24 releases the pressure on the lock tongue 22, and the lock tongue 22 resets under the action of the spring 23, releasing the lock core 21 from locking the lock rod 41.

[0035] The working process of the mechanical module 2 is as follows: when unlocking, the driver 25 rotates and drives the cam 24 to rotate in the cam hole 212, so that the large diameter end of the cam 24 leaves the lock tongue 22. In this case, the lock tongue 22 retracts due to the restoring force of the spring 23 and leaves the lock slot 411, thereby releasing the lock of the lock rod 41. The lock rod 41 can be easily pulled out of the lock hole 211, thereby completing the unlocking operation. When locking, the lock rod 41 must first be inserted into the lock hole 211. At this time, the driver 25 rotates and drives the cam 24 to rotate in the cam hole 212, so that the large diameter end of the cam 24 abuts the lock tongue 22. In this case, the lock tongue 22 moves and is embedded in the lock slot 411 due to the abutting force of the cam 24. Based on the cooperation between the lock tongue 22 and the lock slot 411, the lock rod 41 cannot be pulled out of the lock hole 211, thereby achieving the locking of the lock rod 41.

[0036] The parallel arrangement of the cam hole 212 and the lock hole 211 makes the layout more compact, helping to reduce the overall size of the lock, making it more adaptable to various installation environments. It also ensures that the cam 24 rotates in coordination with the movement trajectory of the lock core 21, reducing jamming or wear caused by inconsistent movement, helping to maintain the stability of the lock when subjected to force, and reducing deformation or damage caused by uneven force.

[0037] In the waterproof logistics electronic lock, the driver 25 is configured as a motor in the prior art, which has a waterproof structure.

[0038] In an embodiment provided in the present disclosure, a position detection device 51 is provided in the lock hole 211 for detecting the position information of the lock rod 41 in the lock hole 211; an angle detection device 52 is provided on the output shaft for detecting the rotation angle information of the output shaft; the position detection device 51 and the angle detection device 52 are both communicatively connected to the electronic module 1, and the electronic module 1 is communicatively connected to the driver 25.

[0039] Specifically, the position detection device 51 is installed in the lock hole 211 and is used to detect the position of the lock rod 41 in the lock hole 211 in real time. By accurately measuring the position of the lock rod 41, the accuracy of the lock in the locked and unlocked states can be ensured. The angle detection device 52 is installed on the output shaft and is used to detect the rotation angle of the output shaft. This helps monitor the movement of the cam 24 or other mechanical components connected to the output shaft.

[0040] In this disclosure, both the position detection device 51 and the angle detection device 52 are connected to the electronic module 1 via a communication link. The electronic module 1 serves as a data processing and control center, receiving and processing signals from the detection devices. The electronic module 1 is also communicatively connected to the driver 25, sending commands to the driver 25 based on the processed data to control the locking and unlocking of the lock.

[0041] The lock can achieve precise locking and unlocking control through the position detection device 51 and the angle detection device 52. Real-time data transmission and processing ensures the reliability of the lock in complex environments, improves the intelligence level of the lock, and makes it more adaptable to the needs of the modern logistics industry.

[0042] Specifically, the position detection device 51 uses a laser distance sensor, and the angle detection device 52 uses an angle sensor. Thus, the position of the lock rod 41 and the rotation angle of the driver 25 are detected, ensuring that the lock tongue 22 can accurately lock or unlock the lock rod 41.

[0043] It should be noted that both the position detection device 51 and the angle detection device 52 are sealed with a waterproof structure, thereby ensuring the safety and reliability during their use.

[0044] In one embodiment provided by the present disclosure, the lock groove 411 is configured as an annular groove; the groove wall of the lock groove 411 is configured as a curved surface, and the end face of the lock tongue 22 is configured as a spherical surface that matches the lock groove 411. The design of the annular groove allows the lock tongue 22 to be embedded in the lock groove 411 from multiple directions, increasing the flexibility and adaptability of the locking. The lock tongue 22 with a spherical end face can better adapt to the curved groove wall of the annular groove, ensuring close contact and locking at any position. Through the cooperation of the curved groove wall and the spherical end face, the lock tongue 22 can withstand forces from multiple directions in the locked state, thereby enhancing the stability of the locking and reducing the risk of unlocking due to external factors such as vibration and impact.

[0045] In addition, compared with flat surface contact, curved surface contact can disperse contact pressure and reduce the risk of wear and damage, so that the lock tongue 22 on the spherical end face can slide more smoothly when inserting into and exiting the annular groove, reducing friction and wear.

[0046] In one embodiment provided by the present disclosure, the lock rope 4 is fixedly connected to the housing 3 via a lock post 42; a slot is provided on the lock post 42, and a limit plate 7 is provided in the mechanical compartment 31, and a limit slot is provided on the limit plate 7 that matches the slot; wherein the size of the limit slot is set so that the lock post 42 can only be fixed in the limit slot in the horizontal direction; the top and bottom walls of the slot are respectively in contact with the limit plate 7 to limit the freedom of the lock post 42 in the vertical direction.

[0047] Specifically, the lock post 42 is provided with a slot, while the mechanical compartment 31 is provided with a stopper plate 7. The stopper plate 7 has a matching stopper slot, allowing the lock post 42 to be horizontally retained within the stopper slot, ensuring the horizontal stability of the lock post 42. To enhance the retention of the lock post 42, the stopper slot is precisely sized to only allow the lock post 42 to engage horizontally, effectively preventing the lock post 42 from shaking or shifting in other directions. Furthermore, the top and bottom walls of the slot abut against the stopper plate 7, restricting the lock post 42's vertical freedom and further enhancing the overall stability of the lock.

[0048] Through the above technical solution, the lock column 42 can be quickly assembled, and at the same time, the stability and safety of the lock rope 4 can be ensured, so that the waterproof logistics electronic lock can cope with various complex environments in the logistics industry and ensure the safe transportation of goods.

[0049] In the present disclosure, the side walls of the card slot are configured as a first plane, and the fitting surface between the limiting slot and the first plane is configured as a second plane, ensuring that the fitting between the card slot and the limiting slot is tight and stable, thereby improving the overall performance and reliability of the lock.

[0050] Specifically, the design of the first plane and the second plane enables the card slot and the limit groove to form a surface-to-surface fit when in contact, rather than point or line contact. This surface contact design can disperse the contact pressure, reduce the risk of wear and damage, and improve the stability and precision of the fit. In addition, the design of the plane fit is also easy to process and manufacture. During the manufacturing process, the flatness and precision of the first plane and the second plane can be ensured through precise machining or mold forming, thereby achieving a tight fit between the card slot and the limit groove.

[0051] In an embodiment provided by the present disclosure, the waterproof logistics electronic lock also includes an induction core 8, which is communicatively connected to the electronic module 1 and the alarm; the lock rope 4 includes a rope body made of multiple strands of steel wire ropes 43, and multiple groups of steel wire ropes 43 are wrapped around the outer periphery of the induction core 8, and the outer periphery of the steel wire ropes 43 is covered with an insulating plastic layer 44, thereby providing a certain degree of protection for the internal steel wire ropes 43 and the induction core 8.

[0052] The lock cord 4 comprises a rope body made of multiple strands of steel wire rope 43, which is wrapped around the outer periphery of the inductive core 8. This design ensures the strength of the lock cord 4 while protecting the internal inductive core 8. The inductive core 8 is connected to the electronic module 1 and the alarm, capable of real-time monitoring of the lock's status and triggering an alarm in abnormal situations. For example, if the lock cord 4 is forcibly cut by external force, the alarm system can be triggered. At the same time, the electronic module 1 can transmit this information to the terminal through the electronic module 1, so that the status of the item can be tracked and investigated in a timely manner. As a result, this waterproof logistics electronic lock combines waterproofness, intelligent sensing, and high strength, providing higher security for logistics and transportation.

[0053] In the present disclosure, one end of the locking rope 4 is fixedly connected to the housing 3 through a locking column 42, and the other end is connected to the mechanical module 2 through a locking rod 41; this double-end fixed design ensures the stability of the locking rope 4 in the lock and prevents the locking rope 4 from loosening or falling off due to external force.

[0054] The lock cylinder 42 and lock rod 41 are each provided with a sealing groove, in which a sealing ring 6 is correspondingly embedded. The sealing ring 6 seals against the housing 3, providing a certain sealing effect, preventing moisture, dust, and other impurities from entering the lock, thereby protecting the electronic components and mechanical structure inside the lock from damage. This sealing design not only improves the lock's waterproof performance, but also extends its service life, providing higher security for logistics transportation, enabling the logistics electronic lock to function normally in various harsh environments, and meeting the high requirements of the logistics industry for locks.

[0055] In the present disclosure, the electronic module 1 includes a controller, and the controller is configured as a Raspberry Pi (a single-chip computer development board). The specific Raspberry Pi model selected is RP2040 RP2-B2 QFN56 ARM Cortex-M0.

[0056] Specifically, in the present invention, the controller may be configured as a central processing unit (CPU). In other embodiments, the controller may be configured as a digital signal processor (DSP), an application-specific integrated circuit (ASIC), or a field-programmable gate array (FPGA).

[0057] In the present disclosure, the controller is communicatively connected to the position detection device 51, the angle detection device 52, and the driver 25 via cables. In other embodiments, the controller may be connected to the position detection device 51, the angle detection device 52, and the driver 25 via a wireless communication module, such as a WiFi module or a Beken Bluetooth chip module. Those skilled in the art can flexibly configure the configuration based on the technical concepts of the present disclosure.

[0058] Furthermore, the electronic module 1 also includes a wireless communication module, such as the aforementioned WiFi module and Beken Bluetooth chip module.

[0059] Finally, it should be noted that the present invention is not limited to the aforementioned optional embodiments. Anyone can derive various other product forms based on the teachings of this invention. The aforementioned specific embodiments should not be construed as limiting the scope of protection of the present invention. The scope of protection of the present invention shall be determined by the claims, and the specification may be used to interpret the claims.
