Description

Technical Field

[0001] This invention relates to the field of cargo transportation auxiliary equipment technology, and more specifically, to an intelligent locking and reinforcement device for cargo transportation. Background Technology

[0002] In road freight transportation, properly placing goods on pallets and transport vehicles is a crucial step in achieving efficient and safe transport. However, current methods for locking and securing goods have many shortcomings. Traditional locking methods often rely on manual operation, which is not only inefficient but also lacks stability during transport. Goods can easily loosen or fall due to vehicle bumps or changes in road conditions, leading to safety accidents and cargo losses. Furthermore, most existing locking devices are complex in structure, inconvenient to operate, and unable to meet the needs of goods of different sizes and shapes, as well as diverse transportation scenarios. They also lack intelligent monitoring and feedback functions, failing to promptly detect and warn of abnormal changes in the locking status, thus posing potential risks to freight transportation.

[0003] In the prior art, a cargo transport device with publication number CN222432176U includes: a driving component including a frame, wheels, and a drive unit; a carrier frame having a bearing surface; a surrounding frame rotating at the end of the carrier frame, with the two ends of the rotation path being a surrounding position and a loading / unloading position, respectively. In the surrounding position, the surrounding frame and the carrier frame enclose a surrounding cavity with an open top. In the loading / unloading position, the surrounding frame is used for transporting goods and shelves; and a locking component for locking the surrounding frame onto the carrier frame. The cargo transport device rotates the surrounding frame to the loading / unloading position to allow goods shelves to pass through for transport between the carrier frame and the ground, thus realizing loading and unloading operations. By rotating the surrounding frame to the surrounding position and locking it in place using the locking component, the surrounding frame and the carrier frame enclose a surrounding cavity, preventing goods from falling and thus achieving safe transport.

[0004] However, this technology has the following significant drawbacks: it relies solely on mechanical fastening devices to secure goods, but cannot adjust according to the shape and size of the goods, and lacks an effective authentication mechanism, making it difficult to ensure the legitimacy and professionalism of the operators. During cargo transportation, unauthorized operation by unauthorized personnel or accidental unlocking of goods due to operator error may lead to cargo loss, damage, and other security issues, weakening the device's ability to ensure the safety of cargo loading. Furthermore, it cannot dynamically adjust based on real-time conditions during transportation. Due to the lack of advanced control systems and sensor feedback mechanisms, it cannot automatically and accurately adjust the locking force and reinforcement parameters based on changes in the weight, volume, and shape of the goods, as well as road conditions and vehicle vibrations during transportation, thus failing to effectively control the stability of goods during transport. This makes goods prone to tilting, loosening, or even falling during long-term transportation, especially for high-value, fragile, or goods with special requirements for transport stability, greatly increasing transportation risks and potential losses, and failing to meet the high requirements of modern logistics transportation for cargo safety and stability. Based on the above problems, there is an urgent need to develop an intelligent locking and reinforcement device for cargo transportation to overcome the shortcomings of existing technologies and improve the safety and reliability of cargo transportation. Summary of the Invention

[0005] To address the shortcomings of existing cargo transportation devices, this invention proposes an intelligent locking and reinforcement device for cargo transportation. This device integrates fingerprint or facial recognition technology into traditional mechanical fixing, accurately verifying the operator's identity and enhancing cargo transportation security. Simultaneously, it is equipped with an intelligent control system that automatically and precisely adjusts the locking force and reinforcement parameters, effectively ensuring the stability of cargo throughout the transportation process.

[0023] To achieve the above-mentioned objectives, the present invention employs the following technical means. The specific embodiments, structures, features, and effects of the present invention will be described in detail below with reference to the accompanying drawings and specific examples.

[0024] Example 1 Please see Figures 1 to 8 This embodiment provides an intelligent locking and reinforcement device for cargo transportation, including a cargo pallet 1, a second servo motor 1201 and a third servo motor 1205. The cargo pallet 1 includes a placement plate 2, the top of the cargo pallet 1 is detachably connected to the placement plate 2, the inner wall of the placement plate 2 is rotatably connected to a rotating rod 3, the outer wall of the rotating rod 3 is slidably connected to a reinforcement rod 4 that is slidably connected to the outer wall of the placement plate 2, and a monitoring sensor 5 is provided on the top of the reinforcement rod 4. The cargo pallet 1 also includes: a reinforcement mechanism 6, disposed on the outer wall of the reinforcement rod 4; a biometric panel 7, disposed on the surface of the reinforcement mechanism 6; a face recognition camera 8, disposed on the surface of the biometric panel 7; a control system module 10, disposed inside the placement plate 2; a signal transmission module 11, disposed on one side of the control system module 10; and an adjustment mechanism 12, disposed on the outer wall of the reinforcement rod 4. The reinforcement mechanism 6 includes a reinforcement plate 604, a fixing groove 605, and a buffer module 606. A first servo motor 601 is fixedly connected to the outer wall of the reinforcement mechanism 6. The output end of the first servo motor 601 is fixedly connected to a first bevel gear set 602 that is rotatably connected to the inner wall of the reinforcement mechanism 6. A first threaded rod 603 is fixedly connected to the outer wall of the first bevel gear set 602. A reinforcement plate 604 that is slidably connected to the outer wall of the reinforcement mechanism 6 is threadedly connected to the outer wall of the first threaded rod 603. A fixing groove 605 is provided at the connection between the outer wall of the reinforcement mechanism 6 and the reinforcement plate 604. The wall is equipped with a buffer module 606. When different transported goods need to be clamped and fixed by the reinforcement mechanism 6, in order to improve the safety of driving the reinforcement mechanism 6, the transport personnel can identify and record their information through the face recognition camera 8 or fingerprint recognition module 9 on the biometric panel 7. The face recognition camera 8 and fingerprint recognition module 9 are both commercially available mature modules. The face recognition camera 8 is a D66-non-contact face recognition, and the fingerprint recognition module 9 is a four-finger fingerprint collector FAP60. This allows the operator to drive the first servo motor 601 on the reinforcement mechanism 6. The drive of the first servo motor 601 is achieved by rotating the first threaded rod 603, which drives the reinforcement plate 604 to slide along the inner wall of the fixing groove 605. The centering and sliding of the reinforcement plate 604 clamps and fixes the goods at different fixing points. Through the double locking mechanism, biometric and intelligent control, and adaptive adjustment of the reinforcement frame, the stability, safety and efficiency of the goods during transportation are ensured.

[0025] like Figure 4 As shown, the biometric panel 7 has a built-in face recognition server connected to the face recognition camera 8, and the face recognition server has a built-in face database, which is connected to CAS-PEAL. The face recognition server is a DH-IVS-F7300 dynamic face recognition server. The biometric panel 7 also has a built-in fingerprint recognition server connected to the fingerprint recognition module 9, and the fingerprint recognition server has a built-in fingerprint database. This allows for the use of face and fingerprint databases to ensure that the reinforcement mechanism 6 is used by a dedicated person, thereby improving the security of the reinforcement device during daily use.

[0026] like Figure 7As shown, the biometric panel 7 is connected to the control system module 10 via a connecting cable, the biometric panel 7 is connected to the signal transmission module 11 via a connecting cable, the signal transmission module 11 is connected to the monitoring sensor 5 via a connecting cable, and the monitoring sensor 5 is connected to the control system module 10 via a connecting cable. The control system module 10 is a PLC controller, consisting of a central processing unit, memory, input / output modules, and a communication interface. The control system module 10 is a Mitsubishi FX3G. The control system module 10 is connected to the signal transmission module 11 via a connecting cable. This allows the control system to dynamically adjust the locking force and reinforcement parameters based on sensor feedback through the settings of the control system module 10, ensuring the stability of the goods during transportation.

[0027] like Figure 6 and Figure 7 As shown, the first servo motor 601 is connected to the control system module 10 via a connecting cable, the second servo motor 1201 is connected to the control system module 10 via a connecting cable, and the third servo motor 1205 is connected to the control system module 10 via a connecting cable. This allows the first servo motor 601 to automatically adjust the structure of the reinforcing frame based on the shape and size information of the goods fed back by the sensors, in order to adapt to the needs of different goods.

[0028] like Figure 5 As shown, the buffer module 606 is made of a high-elasticity buffer material, and the surface of the reinforcing rod 4 is also uniformly provided with buffer modules 606. The use of buffer modules 606 made of high-elasticity buffer material allows the high-elasticity buffer modules 606 to unfold inside the frame and contact the surface of the goods to provide buffer protection.

[0029] Example 2 like Figures 3-8As shown, the adjustment mechanism 12 includes a second bevel gear set 1202, a second threaded rod 1206, and a lifting block 1207. A second servo motor 1201 is fixedly connected to the outer wall of the placement plate 2. The output end of the second servo motor 1201 is fixedly connected to the second bevel gear set 1202, which is rotatably connected to the inner wall of the placement plate 2. A limit groove 1203 is provided at the connection between the outer wall of the rotating rod 3 and the reinforcing rod 4. A sliding groove 1204 is provided at the connection between the outer wall of the placement plate 2 and the reinforcing rod 4. A third servo motor 1205 is provided at the top of the reinforcing rod 4. The output end of the third servo motor 1205 is fixedly connected to the second threaded rod 1206, which is rotatably connected to the outer wall of the reinforcing rod 4. The outer wall of the second threaded rod 1206 is threadedly connected to the lifting block 1207, which is slidably connected to the outer wall of the reinforcing rod 4. By setting a control system module 10, the device's built-in monitoring sensor 5 monitors the locking force, cargo position, and frame status in real time. The monitoring sensor 5 includes a FUTEK sensor. The LSM400 single-point force sensor, AP-5000 displacement sensor, and JD-LM1 sensor ensure the stability of the locking and reinforcement process. The control system dynamically adjusts the locking force and reinforcement parameters based on sensor feedback to ensure the safety of goods during transportation. The intelligent locking and reinforcement device is installed on the transport vehicle or pallet to ensure a tight fit between the device and the goods. After monitoring the specific condition of the transported goods by sensor 5, the cargo dimensions are transmitted to the second servo motor 1201 via signal transmission module 11. Upon receiving the adjustment signal, the second servo motor 1201 drives the second bevel gear set 1202 to rotate. The rotation of the second bevel gear set 1202 causes the rotating rod 3 to rotate. The rotation of the rotating rod 3 causes the reinforcement rod 4 to slide synchronously along the inner walls of the limiting groove 1203 and the sliding groove 1204, allowing for convenient adjustment of the spacing between the reinforcement rods 4. This achieves the effect of adaptive adjustment and fixation of the reinforcement rods 4 for goods of different sizes, effectively improving the safety and efficiency of cargo transportation.

[0030] Example 3 like Figure 3 and Figure 8 As shown, the rotating rod 3 forms a rotating structure with the placement plate 2 through the second servo motor 1201 and the second bevel gear set 1202. The outer wall contour of the rotating rod 3 is cross-shaped, which is conducive to the driving of the second servo motor 1201. Through the connection of the second bevel gear set 1202, the rotating rod 3 is driven to rotate along the inner wall of the placement plate 2, which plays a role in conveniently adjusting the position of the reinforcing rod 4 and achieving the effect of adjusting and reinforcing goods of different sizes.

[0031] like Figure 3 and Figure 4As shown, the reinforcing rod 4 forms a sliding structure between the rotating rod 3, the limiting groove 1203, and the sliding groove 1204. There are four sets of reinforcing rods 4, and the positions of the four sets of reinforcing rods 4 are equidistantly distributed about the rotation center of the rotating rod 3. This facilitates the rotation of the rotating rod 3 and drives the reinforcing rod 4 to slide along the inner wall of the limiting groove 1203 and the sliding groove 1204, thereby achieving the effect of adjusting and reinforcing goods of different sizes.

[0032] like Figure 4 As shown, the lifting block 1207 forms a lifting structure with the reinforcing rod 4 via the second threaded rod 1206. The lifting block 1207 and the reinforcing mechanism 6 are integrally fixedly connected, and the lifting block 1207 and the reinforcing mechanism 6 are arranged in a one-to-one correspondence. This facilitates the rotation of the second threaded rod 1206, which drives the lifting block 1207 to move up and down along the outer wall of the reinforcing rod 4, thus enabling convenient adjustment of the reinforcement position. This allows the reinforcing mechanism 6 to correspond to different fixing points of the goods, ensuring a uniform distribution of locking force. According to the needs of different reinforcement points for transporting different goods, when the third servo motor 1205 receives the adjustment signal, it drives the second threaded rod 1206 to rotate. The rotation of the second threaded rod 1206 drives the lifting block 1207 to slide along the outer wall of the reinforcing rod 4, and conveniently adjusts the position of the reinforcing mechanism 6. This enables convenient adjustment of the reinforcement points for different goods during transportation and allows for the adjustment of loading of goods of different sizes.

[0033] like Figure 6 As shown, the reinforcing plate 604 forms a sliding structure with the fixing groove 605 through the first threaded rod 603. There are two sets of the first threaded rod 603, and the rotation directions of the two sets of the first threaded rod 603 are opposite, which is conducive to the rotation of the first threaded rod 603, which drives the reinforcing plate 604 to slide along the inner wall of the fixing groove 605, thereby playing a convenient role in reinforcing and fixing the transported goods, thereby enhancing the stability of the goods during transportation.

[0034] Working principle: like Figures 1-8 As shown, when using the locking and reinforcement device, firstly, the intelligent locking and reinforcement device for cargo transportation is installed on the transport vehicle or cargo pallet 1 to ensure that the device is in close contact with the cargo contact surface; Secondly, after monitoring the specific situation of the transported goods by the monitoring sensor 5, the size of the goods is transmitted to the second servo motor 1201 through the signal transmission module 11. When the second servo motor 1201 receives the adjustment signal, it drives the second bevel gear set 1202 to rotate. The rotation of the second bevel gear set 1202 drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives the reinforcing rod 4 to slide synchronously along the inner wall of the limiting groove 1203 and the sliding groove 1204, so that the distance between the reinforcing rods 4 can be easily adjusted. This achieves the effect of adaptive adjustment and fixation of the reinforcing rods 4 for goods of different sizes, which can effectively improve the safety and loading efficiency of goods transportation. Furthermore, when different transported goods need to be clamped and fixed by the reinforcement mechanism 6, in order to improve the safety of driving the reinforcement mechanism 6, the transport personnel can identify and record their information through the face recognition camera 8 or fingerprint recognition module 9 on the biometric panel 7, so that the operator can drive the first servo motor 601 on the reinforcement mechanism 6. The drive of the first servo motor 601 is achieved by rotating the first threaded rod 603, which drives the reinforcement plate 604 to slide along the inner wall of the fixing groove 605. The centering and sliding of the reinforcement plate 604 clamps and fixes the goods at different fixing points. Through the double locking mechanism, biometric recognition and intelligent control, and adaptive adjustment of the reinforcement frame, the stability, safety and efficiency of the goods during transportation are ensured. Finally, according to the needs of different cargo transportation reinforcement points, when the third servo motor 1205 receives the adjustment signal, the third servo motor 1205 will drive the second threaded rod 1206 to rotate. The rotation of the second threaded rod 1206 will drive the lifting block 1207 to slide along the outer wall of the reinforcement rod 4, and conveniently adjust the position of the reinforcement mechanism 6, so as to facilitate the adjustment of the reinforcement points of different goods during transportation.
