[0025] The beneficial effects of this invention are:

[0026] Compared to existing robot connections, this invention is used for docking and transmission between two robots, enabling electrical, communication, and power transmission connections. The docking female is a fixed end, while the mating head is a movable end. Through the design of the plug sleeve, plug, docking connector, and plug-locking assembly, this docking mechanism achieves a stable and reliable docking connection, ensuring the safety and stability of the connection between robots or equipment, and is suitable for various industrial scenarios and application environments. The plug and the first and second docking connectors within the plug cavity achieve precise mating and contact, making the robot docking process smoother and more accurate, reducing damage and malfunctions caused by poor docking. The design incorporates a locking drive assembly to drive the mating locking assembly and the plug-locking assembly to engage. This design makes the operation and maintenance of the docking mechanism more convenient, improving the operability and maintenance efficiency of the equipment. The engagement of the plug-locking assembly and the mating locking assembly effectively locks the plug, providing a highly efficient safety guarantee to prevent accidental detachment or loosening during use. This docking mechanism solution is suitable for the docking needs of various robots and automated equipment, and can be flexibly applied to industrial production lines, logistics equipment, and other fields, exhibiting strong versatility and applicability. This invention offers several technical advantages, including a stable and reliable docking connection, precise fit and contact, convenient operation and maintenance, efficient safety assurance, and wide applicability, providing a reliable, safe, and efficient solution for the docking of robots and automated equipment.

[0027] The ratchet connection mechanism acts as a locking mechanism during the connection of the female connector and the mating connector. When the connector is inserted into the mating cavity, the pawl engages with the ratchet groove, preventing the connector from moving backward until it is fully inserted. Only then is the pawl pulled back to its original position by the pull element, allowing it to retract. This improves stability during ratchet mating and prevents backward movement, solving the problem of backward movement that often occurs during existing mating processes. By inserting the connector into the mating cavity of the mating sleeve, a reliable conductive connection is achieved between the head connector and the female connector, ensuring connector stability and reliable electrical transmission. The ratchet connection mechanism, through the design of the ratchet seat, pawl, and ratchet tooth seat, allows for flexible insertion, removal, and fixation of the connector, making connection operations more convenient and reliable. The connection method of the pull element and pawl provides stable hinge tension, thereby enhancing the connector's durability and stability and extending its service life. The connector's robust structure prevents loosening or breakage during insertion and removal, ensuring safe use and reducing the risk of accidental disconnection.

[0028] A docking robot, by placing the docking female seat within a first support and the docking head on a second support, combined with the robust reliability of the aforementioned docking mechanism, achieves a smooth and secure docking connection between the robots, ensuring stability and safety during collaborative operations. The first travel module of the first robot and the second travel module of the second robot cooperate with each other, enabling the two robots to move collaboratively in different directions, thereby improving overall flexibility and working range. The design of the first body, the arrangement of the first travel module, the installation of the first support, and the arrangement of the second body, the second travel module, and the second support, all contribute to a compact structure of the docking robot, facilitating operation and application in confined spaces. The tight and reliable docking connection between the two robots allows for efficient transmission of electrical and communication data, enabling collaborative operation and improving production efficiency and work quality. This invention possesses multiple technical advantages, including a smooth and secure docking connection, multi-dimensional motion collaboration, a compact overall structure, efficient collaborative operation, and ease of maintenance and management, providing a reliable and efficient solution for robot collaborative operations and joint movements.

The second docking connector 22 is disposed in the mating cavity 211. The plug 21 is used to insert into the plug-in cavity 111 so that the first docking connector 12 contacts the second docking connector 22. The locking drive assembly 24 is used to drive the plug-in locking assembly 23 to engage with the plug-in locking assembly 13 to retain the plug 21 in the plug-in cavity 111. This embodiment is used for docking and transmission between two robots, enabling electrical, communication, and power connections. Through the design of the plug-in sleeve 11, plug-in connector 21, docking connector, and plug-in locking assembly 13, this docking mechanism achieves a stable and reliable docking connection, ensuring the safety and stability of the connection between robots or equipment, and is suitable for various industrial scenarios and application environments.

This docking mechanism solution is suitable for the docking needs of various robots and automated equipment, and can be flexibly applied to industrial production lines, logistics equipment, and other fields, exhibiting strong versatility and applicability. This embodiment offers several technical advantages, including a robust and reliable docking connection, precise fit and contact, convenient operation and maintenance, efficient safety assurance, and wide applicability, providing a reliable, safe, and efficient solution for the docking of robots and automated equipment.

[0057] See Figure 8As shown, the opening of the insertion sleeve 11 is provided with an expansion portion 112, which expands outward. A guide block 113 is provided on the side of the insertion sleeve 11 near the expansion portion 112. Multiple guide blocks 113 are arranged in a ring around the inner circumference of the insertion sleeve 11. Multiple guide blocks 212 are evenly distributed in a ring around the outer circumference of the insertion connector 21. A guide groove 213 is formed between adjacent guide blocks 212, and the guide groove 213 is used to engage with the guide blocks 113. Specifically, a guide slope 114 is provided on the opposite side of the guide blocks 113 and 212.

The design of the sealing ring 1231 and the sealing pressure ring 2231 effectively seals the contact plug 223 and the contact groove 123, preventing the intrusion of external dust, moisture, and other substances, thus improving the durability and stability of the docking connector. Reliable electrical connection and effective sealing protection contribute to enhancing the stability and reliability of the overall docking mechanism, making the robot docking process smoother and more reliable.

[0059] See Figures 7-11As shown, the plug-in locking assembly 13 includes a locking positioning element 131 and a locking slot 132. The plug-in connector 21 is provided with a locking positioning groove 215. The locking positioning element 131 is used to cooperate with the locking positioning groove 215 to position the plug-in connector 21. The plug-in locking assembly 23 is provided with a locking tongue 231. The locking drive assembly 24 is used to drive the locking tongue 231 to insert into the locking slot 132. Specifically, the locking drive assembly 24 includes a rotary drive element 241, a drive spindle 242, a turntable 243, and a drive gear disc 244. The connector 21 has a cavity, and a bearing 216 is disposed within the cavity. The drive spindle 242 is rotatably mounted on the bearing 216. The rotary drive element 241 drives the drive spindle 242 to rotate. The turntable 243 is disposed at one end of the drive spindle 242. The drive gear disc 244 is disposed on the turntable 243 and is a helical gear disc. One side of the latch 231 has a helical groove 2311, which is used to engage with the drive gear disc 244. The outer side of the connector 21 has a sliding groove 217, and the drive gear disc 244 drives the helical groove 2311 to cause the latch 231 to slide on the sliding groove 217, so that the latch 231 is inserted into the locking slot 132. In this embodiment, the design of the locking positioning element 131 and the locking positioning groove 215, along with the insertion of the locking tongue 231 into the locking slot 132, achieves precise positioning and fixation of the connector 21, ensuring positional accuracy and stability during the docking process. The locking drive assembly 24, through the coordinated design of components such as the rotary drive element 241, drive spindle 242, turntable 243, and drive gear 244, reliably drives the locking tongue 231 into the locking slot 132, effectively locking the connector. Simultaneously, the reverse operation enables rapid release of the connector, improving operational flexibility and convenience. The design of the drive gear 244 and the helical groove 2311 allows the locking tongue 231 to slide on the slide groove 217, enabling the connector to be quickly and smoothly inserted into the locking slot 132, thereby improving the efficiency and stability of the docking process. The arrangement of components such as bearing 216, drive spindle 242, and turntable 243 provides a robust support and rotation structure for the locking drive assembly 24, improving the overall durability and stability. The design of the locking positioning element 131, the locking drive assembly 24, and the cooperation between the slide 217 and the locking slot 132 ensure safety and reliability during the docking process, reducing the risk caused by misoperation or accidents.

[0060] One end of the locking positioning element 131 extends into the insertion cavity 111. When the connector 21 is inserted into the insertion cavity 111, the locking positioning element 131 is pressed outward to apply a pre-tightening force to the connector 21 until it is engaged with the locking positioning groove 215. After the locking positioning groove 215 engages with the locking positioning element 131, there will be no separation phenomenon after docking with the robot, making the docking more stable and reliable.

[0061] Furthermore, the locking positioning element 131 is a ball-head plunger, and there are multiple of them. They can apply pre-tightening force to the connector in multiple directions, thereby achieving higher structural positioning accuracy and better stability during insertion. The robot-controlled docking mechanism collides with the ball-head plunger to play a pre-fixing role, preventing the robot from separating again.

[0062] A positioning step 218 is provided on the outer side of the cavity, and a positioning ring is installed on the positioning step 218. The positioning ring is used to fix the end face of the bearing 216 in the cavity. A fixing nut 2421 is provided at one end of the drive spindle 242, and the fixing nut 2421 is used to lock one end of the spindle onto the bearing 216. In this embodiment, the design of the positioning step 218 and the positioning ring ensures that the end face of the bearing 216 is accurately fixed and positioned in the cavity, thereby ensuring the stability and reliability of the bearing 216. The setting of the fixing nut 2421 can lock one end of the spindle onto the bearing 216, so that the bearing 216 is effectively fixed and avoids loosening or instability during operation. Through the above design, the bearing 216 in the overall structure is accurately positioned and firmly fixed, which helps to improve the overall stability and reliability of the docking mechanism.

[0063] The system also includes a pull-out assist component 3. One end of the connector 21 is provided with a fixing plate 219. The pull-out assist component 3 includes a connecting post 31, an assist pressure ring 32, and an assist spring 33. One end of the connecting post 31 is mounted on the fixing plate 219. The assist pressure ring 32 is slidably mounted on the connecting post 31. The assist spring 33 is mounted on the connecting post 31 and is used to apply pressure to the pressure ring 32. The assist pressure ring 32 is provided with a support plate 321, one end of which is used to abut against the end face of the insertion sleeve 11. Specifically, the fixing plate 219 has a recess 2191 near the outer periphery of the connector 21. After the connector 21 is inserted into the insertion cavity 111, the end face of the insertion sleeve 11 is used to press the support plate 321 into the recess 2191. In this embodiment, the design of the pull-out assist component 3 can provide additional assistance when the connector 21 needs to be pulled out, making the insertion and removal operation easier and smoother. The pressure applied by the assist spring 33 and the design of the assist ring 32 help to reduce obstruction during robot pull-out. Through the design of components such as the fixed plate 219, connecting post 31, assist ring 32, and support plate 321, the support plate 321 can be pressed into the recess 2191 after the connector 21 is inserted into the insertion cavity 111, thereby achieving contact between the support plate 321 and the end face of the insertion sleeve 11, providing the pulling force. The design of the assist spring 33 and assist ring 32 reduces the floating effect of the robot when pulling out the docking mechanism, reducing friction.

[0064] See Figures 13-17As shown, it also includes a ratchet connecting mechanism 6, which includes a tension element 61, a ratchet seat 62, a pawl 63, and a ratchet tooth seat 64. The wall surface of the insertion sleeve 11 is provided with a ratchet groove 115, which extends into the insertion cavity 111. The ratchet seat 62 is disposed within the ratchet groove 115 and has a hinge groove 621 for hinged engagement of the pawl 63. One end of the tension element 61 is connected to the pawl 63 to provide hinged tension to the pawl 63. The ratchet tooth seat 64 is disposed on the insertion connector 21 and has a toothed groove 641 to engage with the pawl 63. This embodiment serves as a locking mechanism during the connection of the mating female and the mating connector. When the connector 21 is inserted into the insertion cavity 111, the pawl 63 engages with the ratchet groove 115, preventing the connector 21 from moving backward until it is fully inserted. Only then is the pawl 63 pulled back to its original position by the pulling element 61, allowing it to retract and release. This improves stability during ratchet mating and prevents backward movement, solving the problem of easy backward movement during existing mating processes. By inserting the connector 21 into the insertion cavity 111 of the insertion sleeve 11, a reliable conductive connection between the head connector assembly and the female connector assembly is achieved, ensuring connector stability and reliable electrical transmission. The ratchet connection mechanism 6, through the design of the ratchet seat 62, pawl 63, and ratchet tooth seat 64, enables flexible insertion, removal, and fixation of the connector, making connection operations more convenient and reliable. The connector uses a connection method between the pulling element 61 and the pawl 63, providing stable hinge tension, thereby enhancing the connector's durability and stability and extending its service life. The connector has a robust structure, making it less prone to loosening or disconnection during insertion and removal, which helps ensure the safe use of the connector and reduces the risk of accidental disconnection.

[0065] The insert sleeve 11 is provided with a connecting platform 116, and the connecting platform 116 is provided with a connecting element 117. One end of the tension element 61 is connected to the connecting element 117, and the other end is connected to the pawl 63. In this embodiment, the connecting platform 116 is used to cooperate with the installation and connection of the female base plate, and the structure is easy to assemble. The design of the connecting element 117 facilitates the connection and fixation of the tension element 61. In this embodiment, the tension element 61 is used as a shaft-shaped structural component or a screw, the purpose of which is to fix both ends of the tension spring and ensure the tension stability of the pawl 63 during the hinged movement.

[0066] The tension element 61 is a tension spring. The wall of the hinge groove 621 is provided with a hinge positioning groove. Hinge shafts 631 are provided on both sides of the pawl 63, with one end of each hinge shaft 631 extending into the hinge positioning groove. The pawl 63 includes a tension connecting end 632 and a ratchet connecting end 633. The hinge shaft 631 is positioned between the tension connecting end 632 and the ratchet connecting end 633. The tension connecting end 632 connects to the tension element 61, and the ratchet connecting end 633 engages with the toothed groove 641. In this embodiment, the design of the hinge shaft 631 and the hinge positioning groove achieves a stable hinged connection between the pawl 63 and the ratchet connecting end 633, ensuring the reliability and stability of the connection. The tension spring connected to the tension connecting end 632 of the pawl 63 provides stable tension transmission, ensuring stable movement and force transmission of the pawl 63 during operation. Stable articulated connections and tension transmission design help enhance the overall reliability and stability of the connector, ensuring stable connection and transmission quality during long-term use.

[0067] An angle is formed between the tension connection end 632 and the ratchet connection end 633. In this embodiment, a relatively large angle structure is formed so that the ratchet teeth of the mating groove 641 can be formed under the cooperation of the hinge structure and the tension element 61.

[0068] The connector 21 is provided with a ratchet mounting groove, and the ratchet seat 64 is disposed in the ratchet mounting groove. The ratchet seat 64 is provided with a clearance position 642 on one side of the tooth groove 641. In this embodiment, multiple tooth grooves 641 are continuously arranged along the axial direction of the connector 21. The clearance position 642 is used to keep the pawl 63 in a state that does not move backward after it is inserted. When it is inserted into the designated position, it enters the clearance groove. When it needs to be pulled out, it can move backward under the action of the pulling element 61.

[0069] See Figure 18As shown, the directional movement mechanism 7 is disposed on one side of the docking female base 1 and is used to provide directional floating force to the docking female base 1. The directional movement mechanism 7 includes a female base plate 71, a movable base plate 72, a movable guide rail 73, and a movable tension assembly 74. One side of the female base plate 71 is connected to the docking female base 1. The movable base plate 72 is connected to the female base plate 71 through the movable guide rail 73. The movable tension assembly 74 includes a movable tension spring 741. Two tension shafts 742 are provided at both ends of the movable tension spring 741, and the two tension shafts 742 are respectively connected to the movable base plate 72 and the female base plate 71. Two sets of movable tension assemblies 74 are provided, and the two sets of movable tension assemblies 74 are respectively disposed on both sides of the movable base plate 72. In this embodiment, the directional movement mechanism 7 is disposed on the female base plate 71, which can provide directional floating force to the female base plate 71, so that the connector can more flexibly adapt to the insertion operation in different directions during the connection process, thereby improving the applicability and flexibility of the connector. The connection between the movable base plate 72 and the movable guide rail 73 ensures a stable connection between the directional movement mechanism 7 and the female base plate 71, guaranteeing the stability and reliability of the connector during use. The movable tension assembly 74 uses a movable tension spring 741, connected to the movable base plate 72 and the female base plate 71 via a tension shaft 742, providing stable tension transmission and ensuring stable movement and force transmission of the directional movement mechanism 7. The design of the directional movement mechanism 7 allows the connector to better adapt to various insertion requirements at different angles and directions, improving the connector's versatility and adaptability. Specifically, the movable tension assembly 74 has two sets, with the tension shafts 742 in opposite positions (one side has two tension shafts 742 on the movable base plate 72 and the female base plate 71, and the other side has two tension shafts 742 on the female base plate 71 and the movable base plate 72). This generates opposing tension on both sides, keeping the female base plate 71 centered and allowing it to slide along the movable guide rail 73 when floating is required.

[0070] The directional movable mechanism 7 is provided in two sets, and the moving track directions of the two sets of directional movable mechanisms 7 are arranged in a cross shape. In this embodiment, a two-set design is adopted, and the cross-shaped distribution allows it to float along the cross direction, resulting in better stability during connector docking.

[0071] like Figures 1-12As shown, a docking robot includes the aforementioned robot docking mechanism. The docking robot includes a first robot 4 and a second robot 5. A first support 41 is provided at one end of the first robot 4, and a docking female seat 1 is disposed within the first support 41. A second support 51 is provided at one end of the second robot 5, and a docking connector 2 is disposed on the second support 51. The first robot 4 has a first body 42, and first travel modules 43 are provided on both sides of the first body 42. The first support 41 is disposed on the first body 42. The second robot 5 has a second body 52, and second travel modules 53 are provided on both sides of the second body 52. ​​The second support 51 is disposed on the second body 52. ​​This embodiment, by placing the docking female seat 1 within the first support 41 and the docking connector 2 on the second support 51, combined with the aforementioned stable and reliable docking mechanism, achieves a smooth and secure docking connection between the docking robots, ensuring the stability and safety of the robots during joint operations. The first travel module 43 of the first robot 4 and the second travel module 53 of the second robot 5 cooperate with each other, enabling the two robots to move collaboratively in different directions, thereby improving overall flexibility and working range. The design of the first body 42, the arrangement of the first travel module 43, and the installation of the first support 41, as well as the arrangement of the second body 52, the second travel module 53, and the second support 51, makes the entire docking robot structure compact, which is beneficial for operation and application in confined spaces. The tight and reliable docking connection between the two robots allows for efficient transmission of electrical and communication data, enabling collaborative operation and improving production efficiency and work quality. This invention possesses multiple technical advantages, including a stable and robust docking connection, multi-dimensional motion coordination, a compact overall structure, efficient collaborative operation, and ease of maintenance and management, providing a reliable and efficient solution for robots in collaborative operation and joint motion.
