Description

Technical Field

[0001] This invention belongs to the field of container door opening and closing, specifically a smart terminal device for monitoring container door opening and closing. Background Technology

[0002] The limitations of traditional container door control methods: existing container doors mostly rely on mechanical locks and manual operation, lacking intelligent opening and closing control mechanisms, and thus cannot achieve remote or automated management.

[0003] The lack of status monitoring technology, coupled with the absence of integrated sensor systems in traditional containers, makes it difficult to monitor the opening and closing status of doors in real time, as well as environmental parameters inside the container such as temperature, vibration, and location information. This results in insufficient safety and traceability during cargo transportation.

[0004] The door opening adjustment is not flexible. The opening of existing container doors is usually fixed and cannot be dynamically adjusted according to actual needs such as the size of the cargo being loaded or unloaded or space limitations. This limits the adaptability of the application scenarios. Therefore, an intelligent terminal device for monitoring the opening and closing of container doors is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: poor flexibility in adjusting the door opening, the opening of existing container doors is usually fixed and cannot be dynamically adjusted according to actual needs such as the size of the cargo being loaded or unloaded or space limitations, which limits the adaptability of the application scenarios.

[0007] To solve the above technical problems, the present invention provides the following technical solution: an intelligent terminal device for monitoring the opening and closing of container doors, including a container shell, a control box is provided on the upper part of the inner side of the container shell, a photoelectric sensor is provided on the outer side of the control box, a connecting plate is provided on one side of the container shell, a connecting shaft is rotatably connected to the connecting plate, a closed door is connected to the connecting shaft through a connecting arm, and a connecting arm is connected to the control box, with a connecting mechanism hinged to the connecting arm.

[0008] The connecting mechanism is hinged to the closed door, and the connecting plates are distributed at both ends of the connecting shaft.

[0009] As a preferred technical solution for an intelligent terminal device for monitoring the opening and closing of container doors, the connection mechanism includes a second connecting arm and a third connecting arm, with an adjusting sleeve connected between the second connecting arm and the third connecting arm. Both the second connecting arm and the third connecting arm are threadedly connected to the adjusting sleeve, and the threads of the second connecting arm and the third connecting arm have opposite directions.

[0010] Adjust the sleeve to rotate, move relative to the second connecting arm, and move the adjusting sleeve relative to the third connecting arm, so that the second connecting arm and the third connecting arm move away from or closer to each other.

[0011] As a preferred technical solution for an intelligent terminal device for monitoring the opening and closing of container doors, the connecting mechanism also includes a spring, which is located inside the adjusting sleeve. One end of the spring abuts against the connecting arm three, and the other end abuts against the connecting arm two.

[0012] The spring compresses connecting arm two and connecting arm three, creating a compressive force between connecting arm two and the adjusting sleeve, and connecting arm three and the adjusting sleeve. A certain torque is required for connecting arm two and the adjusting sleeve to rotate relative to each other.

[0013] As a preferred technical solution for an intelligent terminal device for monitoring the opening and closing of container doors, the connecting mechanism also includes a control arm and a magnetic block. The control arm is hinged to the adjusting sleeve, and a magnetic block is provided on one side of the middle part of the control arm. The magnetic block is magnetically attracted to the adjusting sleeve, and the outer side of the adjusting sleeve is hexagonal.

[0014] The magnetic attraction between the magnetic block and the adjusting sleeve locks the control arm.

[0015] As a preferred technical solution for an intelligent terminal device for monitoring the opening and closing of container doors, a control component is provided inside the control box. The control component includes a drive motor, a threaded rod, a first sleeve, and a second sleeve. The end of the first connecting arm away from the second connecting arm is hinged to the inner cavity of the control box. The drive motor is provided inside the control box. The power output end of the drive motor is connected to the threaded rod. The threaded rod is rotatably connected to the control box. The threaded rod is threadedly connected to the first sleeve. The second sleeve is rotatably connected to the first sleeve. The second sleeve is movably sleeved with the first connecting arm.

[0016] Sleeve 1 moves along with Sleeve 2. The relative position of Sleeve 2 and Connecting Arm 1 changes continuously, causing Connecting Arm 1 to swing. During the swing of Connecting Arm 1, it pulls the connecting mechanism to move, and the connecting mechanism pulls the closed door to swing in order to open and close.

[0017] As a preferred technical solution for an intelligent terminal device for monitoring the opening and closing of container doors, a receiving box is provided on the top inside the container shell, and a position sensor, a vibration sensor and a temperature sensor are provided inside the receiving box;

[0023] The LoRa wireless module on the circuit board is SX1278, which features LoRa modulation and long-distance transmission.

[0024] The beneficial effects of the intelligent terminal device for monitoring the opening and closing of container doors according to the present invention are as follows: Automated and intelligent control drive motor plus threaded rod sleeve structure: By driving the sleeve to move through the motor, a small force and a small power motor can achieve precise opening and closing of the door, replacing manual operation and improving loading and unloading efficiency.

[0025] Photoelectric sensor: Real-time detection of door opening and closing status, with high accuracy and strong anti-interference capability.

[0026] Integrated sensor network: A combination of GPS positioning, vibration monitoring, and non-contact temperature detection ensures full traceability of goods during transportation.

[0027] Adjustable door opening design with a two-way threaded adjustment sleeve: By rotating the hexagonal sleeve, the reverse thread allows the connecting arm two and connecting arm three to extend and retract, dynamically adjusting the maximum opening angle of the door, such as from 90° to a larger angle.

[0028] Spring preload and magnetic locking: The spring provides stable compressive force, and the magnetic block locks the adjusting sleeve to ensure the structural stability after adjustment.

[0029] Enhanced data transmission and security: LoRa wireless modules support long-distance, low-power data transmission, adapting to complex logistics environments.

[0030] STM32 microcontroller: integrates encryption algorithms to ensure privacy and integrity during data transmission.

[0031] Structural optimization and expandability, articulated connection mechanism: Through the linkage of the control arm and the adjusting sleeve, the mechanical structure can be flexibly adapted to accommodate container doors of different sizes.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0042] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0043] like Figures 1-4 As shown, the present invention proposes an intelligent terminal device for monitoring the opening and closing of container doors, including a container shell 1, a control box 2 is provided on the upper part of the inner side of the container shell 1, a photoelectric sensor 14 is provided on the outer side of the control box 2, a connecting plate 3 is provided on one side of the container shell 1, a connecting shaft 21 is rotatably connected to the connecting plate 3, a closed door 5 is connected to the connecting shaft 21 through a connecting arm 4, and a connecting arm 10 is connected to the control box 2, with a connecting mechanism hinged to the connecting arm 10.

[0044] The connecting mechanism is hinged to the closed door 5, and the connecting plates 3 are distributed at both ends of the connecting shaft 21.

[0045] The connecting mechanism includes a second connecting arm 11 and a third connecting arm 12. An adjusting sleeve 13 is connected between the second connecting arm 11 and the third connecting arm 12. Both the second connecting arm 11 and the third connecting arm 12 are threadedly connected to the adjusting sleeve 13. The threads of the second connecting arm 11 and the third connecting arm 12 have opposite directions.

[0046] The adjusting sleeve 13 rotates and moves relative to the connecting arm 2 11, causing the adjusting sleeve 13 to move relative to the connecting arm 3 12, so that the connecting arm 2 11 and the connecting arm 3 12 move away from or closer to each other.

[0047] The connecting mechanism also includes a spring 17, which is located inside the adjusting sleeve 13. One end of the spring 17 abuts against the connecting arm 3 12 and the other end abuts against the connecting arm 2 11.

[0048] Spring 17 compresses connecting arm 2 11 and connecting arm 3 12, so that connecting arm 2 11 and adjusting sleeve 13, and connecting arm 3 12 and adjusting sleeve 13 maintain a compressive force, increasing the preload between the threads of the threaded connection. At the same time, a large torque is required to achieve relative rotation between connecting arm 2 11 and adjusting sleeve 13, and between connecting arm 3 12 and adjusting sleeve 13.

[0049] The connecting mechanism also includes a control arm 15 and a magnetic block 16. The control arm 15 is hinged to the adjusting sleeve 13. A magnetic block 16 is provided on one side of the middle part of the control arm 15. The magnetic block 16 is magnetically attracted to the adjusting sleeve 13. The outer side of the adjusting sleeve 13 is hexagonal. The magnetic block 16 is connected to a straight surface of the adjusting sleeve 13.

[0050] The magnetic block 16 and the adjusting sleeve 13 magnetically attract each other, locking the control arm 15.

[0051] The control box 2 is provided with a control component inside. The control component includes a drive motor 6, a threaded rod 7, a first sleeve 8, and a second sleeve 9. The end of the first connecting arm 10 away from the second connecting arm 11 is hinged to the inner cavity of the control box 2. The control box 2 is provided with a drive motor 6. The power output end of the drive motor 6 is connected to the threaded rod 7. The threaded rod 7 is rotatably connected to the control box 2. The threaded rod 7 is threadedly connected to the first sleeve 8. The second sleeve 9 is rotatably connected to the first sleeve 8. The second sleeve 9 is movably sleeved with the first connecting arm 10.

[0052] The rotation of the threaded rod 7 drives the sleeve 8 to move. The sleeve 8, along with the sleeve 9, moves along the axis of the threaded rod 7. The relative position of the sleeve 9 and the connecting arm 10 changes continuously, causing the connecting arm 10 to swing. During the swinging process, the connecting arm 10 pulls the connecting mechanism to move, and the connecting mechanism pulls the closed door 5 to swing in order to open and close.

[0053] The top of the container shell 1 is provided with a receiving box 22, and the receiving box 22 is provided with a position sensor 18, a vibration sensor 19 and a temperature sensor 20.

[0054] Photoelectric sensor: CX-411, which can detect the opening and closing status of doors;

[0055] Position sensor: Ublox NEO-7M;

[0056] Vibration sensor: MPU-6050;

[0057] Temperature sensor: MLX90614;

[0058] Circuit board: STM32F103C8T6 minimum system board;

[0059] The LoRa wireless module on the circuit board is SX1278 LoRa modulated for long-distance transmission.

[0060] The magnetic block 16 is made of magnet.

[0061] The specific implementation method is as follows: the drive motor 6 controls the threaded rod 7 to rotate, the threaded rod 7 drives the sleeve 8 to move along the axis of the threaded rod 7, the sleeve 8 moves with the sleeve 9, the relative position of the sleeve 9 and the connecting arm 10 changes continuously, causing the connecting arm 10 to swing, the connecting arm 10 pulls the connecting mechanism to move during the swing, and the connecting mechanism pulls the closed door 5 to swing to realize opening and closing.

[0062] By rotating the adjusting sleeve 13, the distance between the second connecting arm 11 and the third connecting arm 12 can be changed, thereby adjusting the length of the connecting mechanism. By adjusting the length of the connecting mechanism, the maximum opening degree of the closed door 5 can be adjusted.

[0063] The control arm 15 is swung so that it is perpendicular to the axis of the second connecting arm 11. The control arm 15 can be rotated around the central axis of the second connecting arm 11, so that the adjusting sleeve 13 moves relative to the second connecting arm 11 and relative to the third connecting arm 12, so that the second connecting arm 11 and the third connecting arm 12 move away from or closer to each other, and so that the adjusting mechanism extends or shortens.

[0064] When the adjustment mechanism extends, the drive motor 6 controls the threaded rod 7 to rotate, and the threaded rod 7 controls the sleeve 8 to move. When the sleeve 8 swings outward toward the container shell 1, the connecting arm 10 can make the closed door 5 swing at a larger angle, that is, more than 90 degrees, through the adjustment mechanism. When the adjustment mechanism is at its shortest length, the maximum rotation angle of the closed door 5 is 90 degrees.

[0065] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
