Description

Technical Field

[0001] This utility model relates to the field of ship charging technology, and in particular to an automatic docking mechanism for a low-carbon intelligent charging connector for electric ships. Background Technology

[0002] With the development of environmental protection concepts, the concept of low carbon has been gradually applied to the traditional water transport industry. Compared with traditional diesel ships, the low carbon use of electric ships is more in line with the current market environment. Electric ships use batteries or fuel cells and do not produce greenhouse gases such as carbon dioxide when sailing, significantly reducing carbon emissions. Electric motors are more efficient than traditional internal combustion engines, with higher energy utilization rates, further reducing energy consumption. Electric ships can be combined with renewable energy sources such as wind and solar power to further reduce their carbon footprint. With the popularization of electric ships and port shore power systems, the demand for automated docking of ship charging connectors is becoming increasingly urgent.

[0003] Currently, traditional charging connector docking still has certain drawbacks. For example, small vessels often use manual plugging and unplugging of charging connectors, requiring operators to work at close range under swaying conditions, posing safety hazards such as electric shock and mechanical injuries. Semi-automatic docking devices mostly use guide rail positioning + electric push rod drive schemes, which reduce manual intervention, but have insufficient single-degree-of-freedom compensation capabilities, making it difficult to accurately dock and charge when the hull encounters roll, pitch, or other deviations caused by wind and waves. In summary, current automatic docking technology for marine charging connectors still has significant room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide an automatic docking mechanism for low-carbon intelligent charging connectors for electric ships, which solves the problem of insufficient safety and reliability of traditional charging connector docking. It has the advantages of more accurate automated docking, less charging connector loss, and longer service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic docking mechanism for a low-carbon intelligent charging connector for electric ships includes a charging connector and a charging interface. The charging connector is pushed to the charging interface by a flexible robotic arm mounted on an electric slide. A guide cone is installed around the charging connector, and the guide cone matches a guide groove installed on the charging interface. Multiple dynamic limiting mechanisms are also circumferentially distributed on the guide cone. Each dynamic limiting mechanism is a lever structure including a connecting rod. One end of the connecting rod extends into the interior of the guide cone and is fitted with a pressure plate, while the other end extends out of the guide cone and is fitted with a roller. Under normal conditions, the connecting rod, through the rotational force provided by the torsion spring shaft, causes the pressure plate to press against the outer wall of the charging interface, causing the guide cone and the charging connector to move synchronously. When the guide cone moves within the guide groove, the inner wall of the guide groove squeezes the roller, causing the pressure plate to leave the outer wall of the charging interface, thus separating the charging connector from the guide cone.

[0007] Preferably, an installation slot is provided through the outer wall of the guide cone, and the connecting rod is installed in the installation slot through a torsion spring shaft.

[0008] Preferably, the outer wall of the charging connector is fitted with a rubber sleeve, and the pressure plate fits against the rubber sleeve when pressed, and the outer diameter of the rubber sleeve matches the inner diameter of one end of the guide cone in the insertion direction.

[0009] Preferably, the bottom of the compression plate is provided with a protrusion, and the outer wall of the rubber sleeve is provided with a recess.

[0010] Preferably, the inner wall of the guide cone is further provided with a locking block, which is used to restrict the charging connector from being pulled out from the end away from the insertion direction of the guide cone.

[0011] Preferably, the inner wall of the charging interface is provided with a locking groove, and the outer wall of the charging connector is equipped with a buckle controlled by an electromagnetic locking mechanism, the buckle matching the locking groove.

[0012] Preferably, the electromagnetic locking mechanism includes an inner groove formed on the outer wall of the charging connector, a buckle installed in the inner groove that can extend out of the inner groove from the top, the bottom of the buckle being connected to the inner groove by a spring, and an electromagnet installed in the inner groove for magnetically attracting the buckle to be inside the inner groove and compressing the spring when energized.

[0013] Preferably, the flexible robotic arm is connected to a charging connector via a conveyor rod, and a cable electrically connected to the charging connector is installed inside the conveyor rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting a guide cone on the charging connector and a guide groove on the charging interface, the direction of the charging connector can be finely adjusted during the movement of the guide cone within the guide groove, and it can be accurately inserted into the charging interface. Furthermore, the outer wall of the guide cone contacts the inner wall of the guide groove through rollers, reducing the friction during the movement of the guide cone and reducing the wear of the guide cone.

[0016] 2. The dynamic limiting mechanism of the lever structure allows the guide cone and the charging connector to separate and no longer advance synchronously after the roller is squeezed. This design ensures that the charging connector is always hidden inside the guide cone until it is fully inserted into the guide groove, after which the charging connector extends out of the guide cone and is inserted into the charging interface, effectively protecting the charging connector.

[0017] 3. By setting up an electromagnetic locking mechanism, the charging connector can be quickly locked in the inserted state, making plugging and unplugging more convenient and efficient. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, the automatic docking mechanism of the low-carbon intelligent charging connector for electric ships includes a charging connector 6 and a charging interface 10. The charging connector 6 is pushed to the charging interface 10 by a flexible robotic arm 2 mounted on an electric slide table 1. The electric slide table 1 can be selected as an XYZ three-axis slide table, which can realize horizontal movement in the XY axis directions in the horizontal plane, and vertical movement along the Z axis in the vertical case. The electric slide table 1 can initially align the charging connector 6 with the charging interface 10. The flexible robotic arm 2, as a pushing device, can push the charging connector 6 into the charging interface 10 to complete the docking. The flexible robotic arm 2 is chosen here to provide room for fine-tuning of the charging connector 6. Because the displacement of the electric slide table 1 can only achieve initial alignment, the charging connector 6 must move slightly to achieve precise alignment with the charging interface 10. If a rigid robotic arm is used, it cannot move slightly and can only rely on the electric slide table 1 for correction. This places too high a precision requirement on the electric slide table 1 and makes adjustment difficult, making it impossible to achieve precise docking easily and conveniently. Therefore, the following text describes how the flexible robotic arm 2 provides the range of motion to precisely align the charging connector 6 and the charging interface 10.

[0027] like Figure 2As shown, a guide cone 5 is installed around the charging connector 6. The guide cone 5 matches the guide groove 12 installed on the charging interface 10. Multiple dynamic limiting mechanisms 9 are also circumferentially distributed on the guide cone 5. Each dynamic limiting mechanism 9 is a lever structure including a connecting rod 13. One end of the connecting rod 13 extends into the interior of the guide cone 5 and is fitted with a pressure plate 16. The other end extends out of the guide cone 5 and is fitted with a roller 15. Under normal conditions, the connecting rod 13, through the rotational force provided by the torsion spring shaft 14, causes the pressure plate 16 to press against the outer wall of the charging interface 10, causing the guide cone 5 and the charging connector 6 to move synchronously. When the guide cone 5 moves within the guide groove 12, the inner wall of the guide groove 12 squeezes the roller 15, causing the pressure plate 16 to leave the outer wall of the charging interface 10, thus separating the charging connector 6 from the guide cone 5. The movement of the guide cone 5 within the guide groove 12, since both... It has a conical structure, so during the movement of the guide cone 5, it gradually becomes coaxial with the guide groove 12 and completes the axis alignment, so that the charging connector 6 and the charging interface 10 can also be aligned and plugged in. In order to avoid excessive wear caused by the movement of the guide cone 5 in the guide groove 12 and to avoid damage to the charging connector 6, rollers 15 are installed on the outer wall of the guide cone 5. The rollers 15 reduce friction and reduce the wear of the guide cone 5. Moreover, the charging connector 6 is hidden inside the guide cone 5 and will not be easily damaged by collision. The charging connector 6 can be hidden in the guide cone 5 when it is not plugged in, but the guide cone 5 will also hinder the plugging of the charging connector 6. Therefore, through the dynamic limiting mechanism 9, the charging connector 6 can be inside the guide cone 5 when the guide cone 5 is not moved into place, and the charging connector 6 can be extended out of the guide cone 5 after it is moved into place.

[0028] like Figure 3 As shown, this is a specific component of the dynamic limiting mechanism 9. Multiple pressure plates 16 clamp the charging connector 6, causing it to move synchronously with the guide cone 5. To ensure that the charging connector 6 can extend out of the guide cone 5 after it has reached its designated position, the pressure plates 16 and rollers 15 are connected by a lever structure connecting rod 13. Figure 2 The diagram shows the state before the charging connector 6 and charging interface 10 are aligned and plugged in. At this time, the charging connector 6 is hidden inside the guide cone 5. The pressure plates 16 distributed around the circumference are pressed tightly against the outer wall of the charging connector 6 by the torque of the torsion spring shaft 14. The movement of the charging connector 6 will also move the guide cone 5, and the roller 15 is also in a tilted state. As the guide cone 5 goes deeper into the guide groove 12, the roller 15 adheres to the inner wall of the guide groove 12, gradually correcting the guide cone 5 until alignment is completed. Figure 5 The diagram shows the state after alignment and insertion. Roller 15 is squeezed by guide cone 5 and moves towards charging connector 6. At this time, due to the lever principle, pressure plate 16 moves away from charging connector 6, and charging connector 6 separates from guide cone 5, so it continues to move forward and insert into charging interface 10. Guide cone 5 also stops because roller 15 is squeezed, so it will not generate too much collision force with guide groove 12.

[0029] A mounting slot 23 is provided through the outer wall of the guide cone 5. The connecting rod 13 is installed in the mounting slot 23 via a torsion spring shaft 14. To ensure that the movement of the roller 15 can drive the movement of the pressure plate 16, the mounting slot 23 needs to penetrate the outer wall of the guide cone 5, and the torsion spring shaft 14 serves as the fulcrum for the lever movement. Figure 2 and 3 As shown, a rubber sleeve 8 is fitted onto the outer wall of the charging connector 6. The pressure plate 16 fits against the rubber sleeve 8 when pressed, and the outer diameter of the rubber sleeve 8 matches the inner diameter of one end of the guide cone 5 in the insertion direction. The rubber sleeve 8 prevents the pressure plate 16 from directly contacting the charging connector 6 and causing wear. Furthermore, the rubber sleeve 8 provides damping for the movement of the charging connector 6 within the guide cone 5, preventing impact when the charging connector 6 is finally inserted into the charging interface 10, effectively protecting the charging connector 6 and extending its service life.

[0030] Since the synchronous movement of the charging connector 6 and the guide cone 5 is entirely achieved by locking the two together with the pressure plate 16, in order to increase the friction between the pressure plate 16 and the rubber sleeve 8 and prevent the guide cone 5 from sliding relative to the charging connector 6 before it is fully in place, the bottom of the pressure plate 16 is provided with a protrusion 17 and the outer wall of the rubber sleeve 8 is provided with a recess. The rubber sleeve 8 not only has strong friction itself, but the cooperation between the protrusion 17 and the recess makes it easier to restrict the horizontal displacement of the charging connector 6 and the guide cone 5, and does not affect the pressure plate 16 leaving the rubber sleeve 8.

[0031] like Figure 2 and Figure 5 As shown, the inner wall of the guide cone 5 is also provided with a locking block 7. The locking block 7 is used to restrict the charging connector 6 from being pulled out from the end away from the insertion direction of the guide cone 5. Since the above only mentions how the charging connector 6 is inserted into the charging interface 10, when the charging connector 6 is pulled out, because the roller 15 is still in a squeezed state, the charging connector 6 can slide relative to the guide cone 5. The flexible robotic arm 2 can only pull the charging connector 6 to restore the state of being hidden in the guide cone 5. In order for the guide cone 5 to also be able to be pulled out of the guide groove 12, the locking block 7 is set so that when the charging connector 6 continues to be pulled out, it drives the guide cone 5 to leave the guide groove 12, the squeezing force of the roller 15 disappears, and the elastic torsional force of the torsion spring shaft 14 restores the pressure plate 16 to squeeze the charging connector 6.

[0032] like Figure 5 and Figure 6As shown, a locking groove 11 is provided on the inner wall of the charging interface 10, and a buckle 20 controlled by an electromagnetic locking mechanism 18 is installed on the outer wall of the charging connector 6. The buckle 20 matches the locking groove 11. Selecting the electromagnetic locking mechanism 18 can improve the response efficiency of the buckle 20 locking. After the charging connector 6 is inserted into the charging interface 10, the buckle 20 pops out and locks instantly, preventing power outages during charging. The electromagnetic locking mechanism 18 also makes it easy to control the buckle 20 to leave the locking groove 11, making it easy to control unlocking. The electromagnetic locking mechanism 18 includes an inner groove 19 formed on the outer wall of the charging connector 6. A buckle 20 is installed in the inner groove 19 and can extend out of the inner groove 19 from the top. The bottom of the buckle 20 is connected to the inner groove 19 by a spring 22. An electromagnet 21 is installed in the inner groove 19 to magnetically attract the buckle 20 into the inner groove 19 and compress the spring 22 when energized. When unlocked, as the electromagnet 21 is energized, the magnetic attraction causes the buckle 20 to retract into the inner groove 19, completing the unlocking operation. The spring 22 stores elastic potential energy. When the electromagnet 21 is de-energized, the magnetic attraction disappears, and the elastic force of the spring 22 can instantly push the buckle 20 into the locking groove 11, completing the locking operation.

[0033] like Figure 1 As shown, the flexible robotic arm 2 is connected to the charging connector 6 via the conveying rod 3. The cable 4, which is electrically connected to the charging connector 6, is installed inside the conveying rod 3. The conveying rod 3 is hollow to facilitate pushing and pulling the charging connector 6, so that the cable 4 can be dragged inside and move with the charging connector 6.
