[0057] In modern industrial production and logistics, the docking efficiency between tractor-trailers and material cars directly impacts the smoothness of the entire production chain and the rapid response capability of logistics. Efficient, accurate, and rapid docking methods can significantly improve material handling speed, thereby increasing production efficiency and reducing logistics costs. However, traditional docking methods have significant shortcomings in this regard, mainly in the following aspects:

[0058] In traditional docking methods, the connection and separation of the tractor and the material car mostly rely on manual operation. Operators need to manually adjust the hook or other connecting devices of the tractor according to the position and angle of the material car. This method, which relies on visual observation and manual adjustment, is not only time-consuming, but also prone to docking failure or unstable connection due to human judgment errors, increasing the time cost and potential safety risks in the material handling process.

[0059] Manual docking makes it difficult to guarantee the accuracy of each connection, especially under heavy loads or when the material cart moves at high speeds. Poor docking stability can cause the material cart to shake or become unhooked during operation, affecting the safety of material handling and operational efficiency.

[0060] In harsh environments such as dust, humidity, and insufficient light, manual docking becomes more difficult, and the accuracy and stability of docking are further reduced, increasing the complexity and danger of the operation.

[0061] While existing technologies attempt to improve docking efficiency by introducing automated docking devices such as magnetic and hydraulic systems, these solutions often come with high initial investment costs and complex maintenance procedures. Magnetic docking devices, although enabling rapid docking, face challenges in maintaining magnetic strength and ensuring the durability of electromagnetic components. Hydraulic docking devices, while providing stable docking forces, have complex structures, require extensive maintenance and upkeep of the hydraulic system, and are susceptible to issues like hydraulic oil leaks, which increase costs and environmental risks. These factors limit the widespread application of these automated docking technologies in industrial production.

[0062] In production environments that require frequent separation and docking, such as material supply on production lines and rapid loading and unloading in warehouses, existing docking structures are often unable to complete these operations quickly. The docking and separation processes are time-consuming, failing to meet the needs of efficient operations and seriously affecting the continuity of production processes and the responsiveness of logistics.

[0063] Therefore, developing an efficient, stable, cost-effective, and easy-to-maintain automatic docking and separation device has become an urgent problem to be solved in modern industrial production and logistics transportation.

[0064] Combination Figure 1 and Figure 3 As shown in the specific embodiment of this application, a docking device for quick docking of a tractor and a material car is provided, comprising: a locking part 10 and a traction part 20. The locking part 10 includes a housing assembly and a wedge block 110. One end of the housing assembly is connected to one of the tractor 30 and the material car 40. The wedge block 110 is movably connected to the housing assembly. One end of the traction part 20 is connected to the other of the tractor 30 and the material car 40. The traction part 20 is detachably connected to the locking part 10. The traction part 20 has a separation position that is separate from the locking part 10, and a working position that is connected to the locking part 10. The wedge block 110 has a locking position and an unlocking position. When the traction part 20 is in the working position, the wedge block 110 can be operated to be in the locking position so that the traction part 20 and the wedge block 110 cooperate.

[0065] By applying the technical solution of this embodiment, the rapid and automatic docking between the tractor 30 and the material car 40 is achieved through the coordinated action of the locking part 10 and the traction part 20. This effectively reduces docking time, improves the continuity and efficiency of the operation, and the locking and unlocking mechanism of the wedge block 110 ensures the stability of the docking, avoids material damage or operation interruption caused by improper docking, further improves the safety of production logistics, and solves the problems of low working efficiency and poor stability of traditional docking methods in the prior art.

[0066] In one exemplary embodiment, such as Figure 2 As shown, the docking device for quick docking of the tractor and the material car further includes: an identification sensor 50, which is connected to one of the latching part 10 and the traction part 20, and is used to obtain the relative position of the other of the latching part 10 and the traction part 20.

[0067] The identification sensor 50 connects to either the latching part 10 or the traction part 20, enabling precise acquisition of their relative position information and ensuring accurate matching during the docking process. This feature significantly reduces the need for manual intervention, lowers labor costs, and avoids docking errors caused by blind spots or poor environmental conditions, enhancing the system's automation level and reliability. More importantly, the use of the identification sensor 50 enables rapid docking and separation, greatly shortening the operation cycle and increasing the speed of production logistics.

[0068] In this embodiment, the docking device for quick docking of the tractor and the material car further includes a cleaning part 60, which is disposed on the snap-fit ​​part 10. The cleaning part 60 is detachably connected to the tractor 20. The cleaning part 60 is spaced apart from the identification sensor 50. When the tractor 20 is in the working position, the cleaning part 60 cooperates with the tractor 20.

[0069] In this embodiment, the cleaning unit 60 is cleverly mounted on the snap-fit ​​part 10, forming a detachable connection with the traction part 20. This innovative layout not only ensures the flexibility and convenience of the cleaning unit 60 during use, but also ensures a reasonable distance between it and the identification sensor 50, avoiding mutual interference and improving the overall stability of the system. When the traction part 20 is in the working position, the cleaning unit 60 can precisely cooperate with it to effectively remove dust and impurities from the surface of the traction part 20, preventing the accumulation of foreign objects from affecting the accuracy and reliability of docking. This feature is particularly important because in complex and changing factory environments, factors such as dust and humidity changes often lead to contamination of docking components, thereby affecting docking efficiency and success rate. The presence of the cleaning unit 60 greatly reduces the preparation time before docking, reduces docking failures caused by inadequate cleaning, and ensures that every docking is completed smoothly and tightly, thereby significantly improving the speed and accuracy of logistics transportation.

[0070] Furthermore, such as Figure 3As shown, the latching part 10 further includes: a latching drive assembly, a drive block 106, a buffer assembly, and a first elastic element 105. The latching drive assembly is disposed on the housing assembly and is spaced apart from the wedge block 110. The drive block 106 is movably connected to the housing assembly. The actuating end of the latching drive assembly is connected to the wedge block 110 through the drive block 106. The buffer assembly is disposed on the housing assembly and is spaced apart from the wedge block 110, the latching drive assembly, and the drive block. The buffer assembly is detachably connected to the traction part 20. When the traction part 20 is in the working position, the traction part 20 cooperates with the buffer assembly. The first elastic element 105 includes at least one. The first end of at least one first elastic element 105 is connected to the housing assembly. The first elastic element 105 is spaced apart from the latching drive assembly, the drive block, and the buffer assembly. The second end of the first elastic element 105 is connected to one end of the wedge block 110. The drive block 106 is moved along a first preset direction to make the wedge block 110 be in a locked or unlocked position.

[0071] In this embodiment, the design of the snap-fit ​​drive assembly, drive block 106, buffer assembly, and first elastic element 105 integrated in the snap-fit ​​part 10 provides a strong guarantee for the rapid and safe docking between the tractor and the material car. The spacing between the snap-fit ​​drive assembly and the wedge block 110, and the movable connection through the drive block 106, constructs a flexible and efficient mechanical linkage system, making the snap-fit ​​action both rapid and accurate. The introduction of the buffer assembly not only absorbs the impact force during docking at a physical level, ensuring a smooth transition in the docking process, but also, through its detachable connection with the tractor 20, enables convenient replacement of the buffer material after wear, extending the service life of the entire docking device. At least one of the first elastic elements 105 is firmly connected to one end of the wedge block 110, while maintaining a distance from the snap-fit ​​drive assembly, drive block, and buffer assembly, forming an elastic support and recovery mechanism. This ensures the stable transition of the wedge block 110 between the locked and unlocked positions, further improving the smoothness and safety of the docking operation. This integrated mechanical and flexible component design not only significantly reduces the complexity of manual operation and improves the level of automation, but also greatly reduces the docking failure rate, playing a crucial role in improving work efficiency and operational safety.

[0072] In one exemplary embodiment, the housing assembly includes a back plate 108, a buffer chamber 104, and a snap-fit ​​housing 102. One side of the back plate 108 is connected to the tractor 30, and the buffer chamber 104 is connected to the other side of the back plate 108. A portion of the buffer assembly is disposed within the buffer chamber 104. The snap-fit ​​housing 102 is connected to the other side of the back plate 108 and is disposed on top of the buffer chamber 104. A snap-fit ​​drive assembly, a drive block 106, and a first elastic member 105 are disposed within the snap-fit ​​housing 102. When the wedge block 110 is in the locked position, a portion of the wedge block 110 extends into the buffer chamber 104. When the wedge block 110 is in the unlocked position, the wedge block 110 is within the snap-fit ​​housing 102.

[0073] In this embodiment, the backplate 108 serves as a hub connecting the tractor 30, the buffer chamber 104, and the snap-fit ​​housing 102. It not only provides stable support but also achieves a compact structural layout and seamless functional integration through its connection to the tractor 30 on one side and its combination with the buffer chamber 104 and the snap-fit ​​housing 102 on the other. This integrated design reduces assembly complexity and improves the mechanical efficiency and space utilization of the entire system. The buffer chamber 104 and its internal buffer components effectively cushion the impact encountered by the tractor 20 during docking, absorbing the energy generated at the moment of docking and preventing equipment damage and operational interruptions caused by hard collisions, thus ensuring system operational safety and efficiency.

[0074] The snap-fit ​​housing 102 connects to the other side of the back plate 108 and is located on top of the buffer chamber 104. It not only provides clear visual guidance and positioning but also enables intelligent control of the wedge block 110 through its internal snap-fit ​​drive assembly, drive block 106, and first elastic element 105. When the wedge block 110 is in the locked position, part of its structure extends into the buffer chamber 104, forming a tight lock with the traction limit plate 202, ensuring stability during traction. When the wedge block 110 is in the unlocked position, it is free within the snap-fit ​​housing 102, facilitating rapid release. This design greatly enhances operational flexibility and safety.

[0075] Furthermore, the snap-fit ​​drive assembly includes: a drive motor 103, a rotating shaft 113, and a protrusion 109. The base of the drive motor 103 is connected to the housing assembly. The first end of the rotating shaft 113 is connected to the main shaft of the drive motor 103, and the second end of the rotating shaft 113 is movably connected to the housing assembly. The protrusion 109 is connected to the side wall of the rotating shaft 113 and is movably connected to the drive block 106. The protrusion 109 is operated to rotate in a second preset direction to move the drive block 106 in a first preset direction.

[0076] In this embodiment, the snap-fit ​​drive assembly utilizes a precise fit between the drive motor 103, the rotating shaft 113, and the protrusion 109, significantly improving the automation level and operational precision during the docking process between the tractor and the material car. The drive motor 103, as the core power source, has its base firmly connected to the outer casing assembly, ensuring the stability and reliability of power transmission. The direct connection between the rotating shaft 113 and the main shaft of the drive motor 103 converts into precise rotational motion, which is then connected to the drive block 106 via the protrusion 109 on the side wall, achieving an efficient conversion from rotation to linear motion. The rotation of the protrusion 109 along a preset direction guides the drive block 106 to move precisely along a set path. This design allows the wedge block 110 to quickly switch between locked and unlocked positions, greatly shortening the docking preparation time and operational complexity, and enhancing the system's response speed and flexibility. Simultaneously, by controlling the speed and direction of the drive motor 103, the docking force can be precisely adjusted, avoiding equipment damage caused by excessive impact force, and ensuring stable docking performance under different environmental conditions.

[0077] In one exemplary embodiment, such as Figure 4 As shown, the buffer assembly includes: a first buffer element 111 and a second buffer element 114. One end of the first buffer element 111 is connected to the outer shell assembly, and the second buffer element 114 is spaced apart from the first buffer element 111. One end of the second buffer element 114 is connected to the outer shell assembly. When the traction part 20 is in the working position, the traction part 20 cooperates with the other end of the first buffer element 111 and the other end of the second buffer element 114 respectively. The wedge block 110 is in the locked position, and part of the wedge block 110 is located between the first buffer element 111 and the second buffer element 114.

[0078] In this embodiment, the double-layer buffering mechanism of the first buffer element 111 and the second buffer element 114 provides excellent shock absorption and stability assurance for the docking between the tractor and the material car. When the traction unit 20 is in the working position, the first buffer element 111 and the second buffer element 114 can effectively absorb and disperse the impact force generated at the moment of docking, avoiding mechanical damage or docking failure that may be caused by direct hard contact, and ensuring the smoothness and safety of the docking process. When the wedge block 110 is in the locked position, part of its structure is cleverly placed between the first buffer element 111 and the second buffer element 114, which not only enhances the compactness of the overall structure, but also utilizes the geometric characteristics of the wedge block 110 to further refine the force distribution during docking, reduce the wear of the buffer elements, and extend their service life.

[0079] Furthermore, such as Figure 5As shown, the first or second buffer element includes a second elastic member 112 and a buffer plate. The first end of the second elastic member 112 is connected to the housing assembly, and the second end of the second elastic member 112 is connected to one side of the buffer plate. When the traction part 20 is in the working position, the buffer plate cooperates with the traction part 20.

[0080] In this embodiment, the design of a first or second buffer element combining a second elastic element 112 and a buffer plate significantly optimizes the flexibility and durability of the docking process in the material handling system. The elastic properties of the second elastic element 112 allow it to absorb and mitigate impact forces instantly upon docking with the material car, effectively preventing equipment damage from hard collisions and ensuring smooth and safe docking. The connection between the buffer plate and the second elastic element 112 not only provides a direct bearing surface for impact forces, but the careful selection of its hardness and elastic coefficient also ensures accuracy and stability during docking. When the traction unit 20 is in the working position, the buffer plate can closely cooperate with it to form a dynamic buffer interface, ensuring smooth docking even under high-speed or heavy-load conditions, reducing the probability of docking failure and improving operational efficiency. Furthermore, the design of the second elastic element 112 also considers wear and fatigue issues during long-term use. Its material selection and structural design allow it to maintain good elastic recovery after withstanding multiple high-intensity impacts, thereby reducing maintenance frequency.

[0081] In one exemplary embodiment, the buffer plate includes a first buffer plate 101 and a second buffer plate 107. One side of the first buffer plate 101 is connected to the second end of the second elastic member 112, and one end of the second buffer plate 107 is connected to one end of the first buffer plate 101 at a preset angle, thereby guiding the second buffer plate 107 when it contacts the traction unit 20. The second buffer plate 107 and the first buffer plate 101 are connected at a preset angle to form a unique guiding structure. When the traction unit 20 contacts the buffer plate, the inclined design of the second buffer plate 107 can guide and mitigate the impact, ensuring that the traction unit 20 smoothly docks with the system, avoiding equipment damage or work interruption that may be caused by direct hard collision, and improving the continuity and safety of the operation. The connection between the first buffer plate 101 and the second end of the second elastic member 112 allows the second elastic member 112 to effectively absorb and disperse the energy when the buffer plate is impacted, reducing the direct impact on the internal structure of the system, protecting the equipment from damage, and extending the service life of the equipment. At the same time, this energy absorption mechanism can also reduce noise and improve the working environment.

[0082] In this embodiment, as Figure 6As shown, the cleaning unit 60 includes a brush plate 601 and a cleaning drive assembly. The brush plate 601 is movably connected to the housing assembly, and multiple brush bristles 602 are connected to the brush plate 601. The base of the cleaning drive assembly is connected to the housing assembly, and the actuator of the cleaning drive assembly is movably connected to the brush plate 601. When the traction unit 20 is in the separated position and moves to the working position and / or when the traction unit 20 is in the working position, the actuator drives the brush plate 601 to move along a third preset direction, and the brush plate 601 drives the multiple brush bristles 602 to move to perform dust removal operations on a portion of the traction unit 20.

[0083] Applying this embodiment, the design of the cleaning unit 60, particularly the brush plate 601 and the cleaning drive assembly, significantly enhances the self-maintenance capability and environmental hygiene standards of the traction unit in the material handling system. The movable connection between the brush plate 601 and the housing assembly, coupled with the meticulous arrangement of multiple bristles 602, automatically removes dust and impurities from the surface of the traction unit 20 during its movement, ensuring that the traction unit 20 maintains optimal condition during each docking and reducing docking misalignment or equipment malfunction caused by external contamination. The cleaning drive assembly, as the power source, has its base securely connected to the housing assembly. The movable connection mechanism between the actuator and the brush plate 601 precisely controls the movement of the brush plate 601, enabling timely initiation of the cleaning program whether the traction unit 20 is moving from the separation position to the working position or stationary in the working position.

[0084] Furthermore, such as Figure 7 As shown, the cleaning drive assembly includes a cleaning drive motor 603, a drive disc 605, and a drive rod 604. The base of the cleaning drive motor 603 is connected to the housing assembly, the drive disc 605 is connected to the main shaft of the cleaning drive motor 603, and the drive disc 605 is spaced apart from the housing assembly. The first end of the drive rod 604 is movably connected to the drive disc 605, and the second end of the drive rod 604 is movably connected to the brush plate 601. The drive disc 605 is rotated in a fourth preset direction to move the drive rod 604 in a third preset direction.

[0085] In this embodiment, the cleaning drive motor 603 serves as the power source, driving the drive disc 605 to rotate. The drive rod 604, connected to the drive disc 605, converts circular motion into linear motion, ensuring that the brush plate 601 moves stably along a preset third direction to complete the dust removal operation. This motion conversion mechanism is ingeniously designed and precisely operated, avoiding energy loss and control difficulties caused by complex movements. The movable connection between the drive rod 604 and the brush plate 601 ensures that they can work together. The bristles 602 on the brush plate 601 can thoroughly remove dust and impurities from the traction unit 20 during movement. This design not only removes visible stains but also cleans hard-to-reach areas through crevices, greatly improving the quality and efficiency of cleaning. The operation of the cleaning drive assembly can be automatically triggered during the movement of the traction unit 20 from the separated position to the working position, or it can be manually activated when the traction unit 20 is in the working position, demonstrating high flexibility and adaptability. It can start the cleaning process in a timely manner according to different scenarios and needs, without affecting the normal operation process, while also allowing for regular maintenance of equipment hygiene and extending equipment life.

[0086] In an exemplary embodiment, the traction unit 20 includes a traction ring 203 and a traction limiting plate 202. One end of the traction ring 203 is connected to another of the traction vehicle 30 and the material vehicle 40. The traction ring 203 is provided with a limiting space 201. The traction limiting plate 202 is disposed within the limiting space 201 and is connected to the traction ring 203. When the wedge block 110 is in the locked position, a portion of the wedge block 110 is located within the limiting space 201.

[0087] In this embodiment, the design of the traction unit 20, especially the combined use of the traction ring 203 and the traction limiting plate 202, greatly enhances the stability and safety of traction operations in the material handling system. One end of the traction ring 203 is firmly connected to either the traction vehicle 30 or the material cart 40. Its internal limiting space 201 is cleverly designed to provide a precise positioning and embedding area for the wedge block 110, ensuring the accuracy and tightness of the traction connection. The traction limiting plate 202 is located within the limiting space 201 and connected to the traction ring 203, not only increasing the rigidity of the structure but also achieving an automatic locking function through dynamic cooperation with the wedge block 110. When the wedge block 110 is in the locked position, part of its structure is precisely embedded within the limiting space 201, forming a double locking mechanism with the traction limiting plate 202. This effectively prevents accidental disengagement due to external impact or vibration during traction, significantly improving operational efficiency and equipment reliability.
