Description

Technical Field

[0001] This invention relates to the field of circuit device technology, and in particular to a charging device for an AGV laser navigation transport vehicle. Background Technology

[0002] AGVs are unmanned vehicles capable of autonomously navigating and performing material handling tasks in industrial or commercial environments. They have a wide range of applications, including warehousing and logistics, production line material handling, aerospace, healthcare, and electronics manufacturing. They can improve production efficiency, reduce operating costs, minimize the risks of manual operation, and provide sustainable material handling solutions. However, current AGV laser-guided transport vehicles often cannot accurately plug into the charging station during automatic charging, and charging is unreliable. Summary of the Invention

[0003] Therefore, it is necessary to provide a charging device for an AGV laser-guided transport vehicle to solve at least one of the aforementioned technical problems.

[0004] A charging device for an AGV laser-guided transport vehicle includes a charging pile, a guide assembly, a rope pulling mechanism, and a cover assembly. The charging pile is placed on the ground and used to charge the AGV laser-guided transport vehicle. The guide assembly is installed at the bottom of the side wall of the charging pile, the rope pulling mechanism is located at the top of the guide assembly, and the cover assembly is installed at the bottom of the side wall of the charging pile. The guide assembly includes two support columns and two guide plates. The two support columns are both abutted against the ground, and the two guide plates are rotatably mounted on the middle of the two support columns by torsion springs. A flipping gap is formed between each guide plate and the charging pile. The rope pulling mechanism... The mechanism includes two pull rope assemblies, which are located above two guide plates respectively. Each guide plate has a first electromagnet at the end furthest from the charging pile. The first electromagnet is electrically connected to the charging pile. Each pull rope assembly includes a connecting rod and a pull rope structure. One end of the connecting rod is fixedly connected to the bottom of the side wall of the charging pile, and the connecting rod is located above the guide plate. The pull rope structure slidably abuts against the top of the connecting rod. The cover assembly includes two slide rails and a cover. Both slide rails are installed at the bottom of the side wall of the charging pile, and both ends of the cover are slidably inserted into the two slide rails respectively.

[0005] The charging station is used to charge transport vehicles. The guide plate of the guide component not only guides the transport vehicle so that the plug component of the transport vehicle can be accurately inserted into the charging socket, but also clamps the transport vehicle during charging, making the charging process smoother. The pull rope mechanism is used to open the cover component. When not charging, the cover component provides a protective cover to prevent dust and debris from the environment from entering the charging socket. When charging, it can lock the transport vehicle in place while the power is on, making the charging process smoother.

[0006] Preferably, the AGV laser-guided transport vehicle includes four sliding wheels, a housing, and a plug assembly. The housing is mounted on top of the four sliding wheels, the plug assembly is inserted into the side wall of the housing, and a first magnet is installed on each of the two side walls of the housing.

[0007] Preferably, the plug assembly includes a plug body, multiple conductive wires and a second magnet. The plug body is fixedly inserted into the side wall of the housing. A conductive groove is opened at the end of the plug body. The multiple conductive wires are all inserted into the side wall of the conductive groove. A locking groove is opened at the top of the plug body. The second magnet is fixedly installed in the locking groove.

[0008] Preferably, the charging pile includes a support platform, a charging body, and a display panel. The charging body is fixedly installed on the top of the support platform, and the display panel is fixedly installed on the side wall of the charging body.

[0009] Preferably, each pull rope mechanism further includes multiple support rods, multiple fixing rings, and pulleys. The bottoms of the multiple support rods are placed on the ground, and the upper ends of the multiple support rods are fixedly connected to the side wall of the connecting rod. The multiple fixing rings are installed on the top of the connecting rod. The pull rope structure slides through the multiple fixing rings. The pulley is installed at the bottom of the side wall of the charging pile, and the pulley is located above the cover.

[0010] Preferably, the pull rope structure includes an ascending section, an abutting section, a connecting section, and a fixing plate. One end of the ascending section is fixedly connected to the top of the cover, one end of the abutting section is connected to the other end of the ascending section, and the abutting section passes through multiple fixing rings. One end of the connecting section is connected to the other end of the abutting section. The fixing plate is fixedly installed on the top of the guide plate at the end away from the charging body, and the other end of the connecting section is fixedly connected to the side wall of the fixing plate.

[0011] Preferably, the rising section includes a lifting section, a winding section, and an inclined section. The lower end of the lifting section is fixedly connected to the top of the cover. The middle part of the winding section is wound around a pulley, and one end of the winding section is fixedly connected to the upper end of the lifting section. One end of the inclined section is fixedly connected to the other end of the winding section, and the other end of the inclined section is fixedly connected to the abutting section.

[0012] Preferably, each slide rail component includes a slider and an expansion block. The slider is installed on the bottom of the side wall of the charging body, and the side wall of the slider is provided with a sliding groove. The two ends of the cover are slidably installed in the sliding groove, and the expansion block is fixedly installed on the top side wall of the sliding groove.

[0013] Preferably, the cover includes a sliding rod, a cover, and a second electromagnet. The two ends of the sliding rod are slidably installed in two sliding grooves. The cover is fixedly installed at the bottom of the sliding rod, and the second electromagnet is fixedly installed at the bottom of the cover. The second electromagnet is electrically connected to the charging body.

[0014] Preferably, a charging socket is provided on the side wall of the charging body, and a cover is provided in the charging socket. The height of the charging socket is the same as the height of the plug body. The guide plate includes a pushing section and a conductive section. The pushing section is located on the side adjacent to the charging body, and the conductive section is located on the side away from the charging body. The first electromagnet is installed on the side wall of the conductive section.

[0015] This invention, by setting up a guiding component, allows the AGV laser-guided transport vehicle to move towards the charging pile when its working power is insufficient. As the transport vehicle approaches the charging pile, it enters the guiding plate of the guiding component. Under the guidance of the guiding plate, the plug component of the transport vehicle can be accurately inserted into the charging socket, preventing the transport vehicle from being inserted crookedly. By setting a first electromagnet, when the transport vehicle approaches the charging pile, it will enter between two guide plates. As the transport vehicle continues to move towards the charging pile, it will be guided by the conductive section of the guide plate into the pushing section. When the transport vehicle enters the pushing section, the outer shell of the transport vehicle will push against the pushing section of the guide plate, causing the pushing section to flip towards the charging body. The conductive section of the guide plate will then flip towards the outer shell of the transport vehicle, ultimately making the guide plate parallel to the side of the outer shell. The conductive section is clamped onto the side wall of the outer shell. When the plug assembly is inserted into the charging socket, the circuit is turned on, the first electromagnet becomes energized, and attracts the first magnet on the side wall of the outer shell, making the conductive section clamp the outer shell even tighter, preventing the transport vehicle from being bumped during charging and thus affecting the charging process. By setting a second electromagnet, when the conductive section of the guide plate flips towards the outer shell of the transport vehicle, the fixing plate moves along with the conductive section. The fixing plate pulls the pull rope structure, which moves through pulleys and multiple fixing rings. This causes the lifting section to pull the sliding rod upward, exposing the charging socket. This allows the plug assembly of the transport vehicle to be accurately inserted into the charging socket. After the sliding rod rises, it pushes against the expansion block. When the plug assembly is inserted into the charging socket, the circuit is connected, the second electromagnet is energized, and it attracts the second magnet. Simultaneously, the second electromagnet is located directly above the locking slot. Because the second magnet is fixed in the locking slot, the second electromagnet pulls the pull rope structure downward, tautning it. The pull rope structure has a certain degree of tensile strength, and the second electromagnet is locked in the locking slot, adhering to the second magnet. This prevents the transport vehicle from being impacted during charging, thus affecting the charging process. By incorporating an expansion block, after the transport vehicle's plug assembly is accurately inserted into the charging socket and charging for a period of time, heat will be generated in the charging area and the bottom of the charging pile's side wall. The bottom of the charging pile's side wall and the sliding body are made of a thermally conductive metal material, which effectively transfers the heat to the expansion block. The expansion block expands due to heat, moving the push-back cover towards the locking slot, allowing the second electromagnet and the second magnet to fit more tightly together. This prevents the transport vehicle from being impacted during charging, thus avoiding any disruption to the charging process. This invention has a clever structure that effectively guides the transport vehicle during charging and ensures a tighter connection between the vehicle and the charging pile, preventing collisions that could affect charging.

[0036] like Figure 3 As shown, a charging socket (not shown) is provided on the side wall of the charging body 22. The cover 520 is placed in the charging socket. The height of the charging socket is the same as the height of the plug body 14. The guide plate 31 includes a pushing section 310 and a conductive section 311. The pushing section 310 is located on the side adjacent to the charging body 22, and the conductive section 311 is located on the side away from the charging body 22. The first electromagnet 24 is installed on the side wall of the conductive section 311.

[0037] During installation: the guide assembly 30 is installed on the bottom side wall of the charging pile 20, the cover assembly 50 is installed on the bottom side wall of the charging pile 20, the two guide plates 31 are rotatably installed on the middle of the two support columns 32 by torsion springs, the two slide rails 51 are installed on the bottom side wall of the charging pile 20, the outer shell 12 is installed on the top of the four sliding wheels 11, and the second magnet 16 is fixedly installed in the slot 18. The charging body 22 is fixedly installed on the top of the support platform 21, the display panel 23 is fixedly installed on the side wall of the charging body 22, multiple fixing rings 44 are installed on the top of the connecting rod 41, the pulley 45 is installed on the bottom of the side wall of the charging pile 20, the fixing plate 423 is fixedly installed on the top of the guide plate 31 away from the charging body 22, the sliding body 53 is installed on the bottom of the side wall of the charging body 22, the two ends of the cover 52 are slidably installed in the sliding groove 55, the expansion block 54 is fixedly installed on the top side wall of the sliding groove 55, the two ends of the sliding rod 522 are slidably installed in the two sliding grooves 55, the cover 520 is fixedly installed on the bottom of the sliding rod 522, the second electromagnet 521 is fixedly installed on the bottom of the cover 520, and the first electromagnet 24 is installed on the side wall of the conductive section 311.

[0038] In use: 1. When the AGV laser-guided transport vehicle 10 has insufficient working power, the AGV laser-guided transport vehicle 10 will move towards the charging pile 20. When the AGV laser-guided transport vehicle 10 approaches the charging pile 20, the AGV laser-guided transport vehicle 10 will enter the guide plate 31 of the guide component 30. Under the guidance of the guide plate 31, the plug component 13 of the AGV laser-guided transport vehicle 10 can be accurately inserted into the charging socket, preventing the AGV laser-guided transport vehicle 10 from being inserted crookedly.

[0039] 2. As the AGV laser-guided transport vehicle 10 approaches the charging pile 20, it will enter the two guide plates 31. The AGV laser-guided transport vehicle 10 continues to move towards the charging pile 20. Guided by the conductive section 311 of the guide plate 31, it will enter the pushing section 310. When the AGV laser-guided transport vehicle 10 enters the pushing section 310, its outer shell 12 will push against the pushing section 310 of the guide plate 31, causing the pushing section 310 to flip towards the charging body 22. The pushing section 310 flips towards the charging body 22, and the conductive section 311 of the guide plate 31 flips towards the outer shell 12 of the AGV laser navigation transport vehicle 10, so that the guide plate 31 is parallel to the side of the outer shell 12. The conductive section 311 is clamped on the side wall of the outer shell 12. When the plug assembly 13 is inserted into the charging socket, the circuit is turned on, the first electromagnet 24 is energized, and attracts the first magnet 19 on the side wall of the outer shell 12, so that the conductive section 311 clamps the outer shell 12 more tightly, preventing the AGV laser navigation transport vehicle 10 from being collided during charging, thus affecting the charging.

[0040] 3. When the conductive section 311 of the guide plate 31 flips toward the outer shell 12 of the AGV laser navigation transport vehicle 10, the fixing plate 423 will move along with the conductive section 311. The fixing plate 423 will pull the pull rope structure 42 to move. The pull rope structure 42 moves in the pulley 45 and multiple fixing rings 44, which in turn causes the lifting section 424 to pull the sliding rod 522 upward, thereby exposing the charging socket. This allows the plug assembly 13 of the AGV laser navigation transport vehicle 10 to be accurately inserted into the charging socket. After the sliding rod 522 rises, it will push against the expansion block 54. When the plug assembly 13 is inserted into the charging socket, the circuit is turned on, the second electromagnet 521 is energized, and attracts the second magnet 16. At the same time, the second electromagnet 521 is located directly above the slot 18. Since the second magnet 16 is fixed in the slot 18, the second electromagnet 521 will pull the pull rope structure 42 downward, making the pull rope structure 42 taut. The pull rope structure 42 has a certain degree of tensile strength, and the second electromagnet 521 will be locked in the slot 18 and fit against the second magnet 16, preventing the AGV laser navigation transport vehicle 10 from being collided with during charging, which would affect the charging process.

[0041] 4. After the plug assembly 13 of the AGV laser-guided transport vehicle 10 is accurately inserted into the charging socket for a period of time, heat will be generated in the charging area and the bottom of the side wall of the charging pile 20. The bottom of the side wall of the charging pile 20 and the sliding body 53 are made of metal thermally conductive material, which can effectively transfer the heat to the expansion block 54. The expansion block 54 expands due to heat, moving the push cover 52 toward the locking slot 18, making the second electromagnet 521 and the second magnet 16 fit more tightly. The AGV laser-guided transport vehicle 10 is impacted during charging, which affects the charging process. After charging is completed, the magnetic field of the second electromagnet 521 disappears, the pull rope structure 42 pulls the second electromagnet 521 out, the second electromagnet 521 separates from the second magnet 16, the magnetic field of the first electromagnet 24 disappears, the magnetic force between the first electromagnet 24 and the first magnet 19 disappears, the AGV laser-guided transport vehicle 10 detaches from the charging socket, and continues to work. The cover 52 also provides the function of a cover when the AGV laser navigation transport vehicle 10 is not being charged, to prevent dust and debris in the environment from entering the charging socket, thereby preventing various charging problems caused by the presence of dust and debris when the AGV laser navigation transport vehicle 10 is being charged.

[0042] By setting up a guide component 30, when the AGV laser-guided transport vehicle 10 has insufficient working power, the AGV laser-guided transport vehicle 10 will move towards the charging pile 20. When the AGV laser-guided transport vehicle 10 approaches the charging pile 20, it will enter the guide plate 31 of the guide component 30. Under the guidance of the guide plate 31, the plug component 13 of the AGV laser-guided transport vehicle 10 can be accurately inserted into the charging socket, preventing the AGV laser-guided transport vehicle 10 from being inserted crookedly. By setting the first electromagnet 24, when the AGV laser-guided transport vehicle 10 approaches the charging pile 20, the AGV laser-guided transport vehicle 10 will enter the two guide plates 31. The AGV laser-guided transport vehicle 10 continues to move towards the charging pile 20. Guided by the conductive section 311 of the guide plate 31, the AGV laser-guided transport vehicle 10 will enter the pushing section 310. When the AGV laser-guided transport vehicle 10 enters the pushing section 310, the outer shell 12 of the AGV laser-guided transport vehicle 10 will push against the pushing section 310 of the guide plate 31, so that the pushing section 310 faces the charging body 22. One side flips, and the pushing section 310 flips towards the charging body 22. The conductive section 311 of the guide plate 31 flips towards the outer shell 12 of the AGV laser navigation transport vehicle 10, so that the guide plate 31 is parallel to the side of the outer shell 12. The conductive section 311 is clamped on the side wall of the outer shell 12. When the plug assembly 13 is inserted into the charging socket, the circuit is turned on, the first electromagnet 24 is energized, and attracts the first magnet 19 on the side wall of the outer shell 12, so that the conductive section 311 clamps the outer shell 12 more tightly, preventing the AGV laser navigation transport vehicle 10 from being collided during charging, thus affecting the charging. By setting a second electromagnet 521, when the conductive section 311 of the guide plate 31 flips toward the outer shell 12 of the AGV laser navigation transport vehicle 10, the fixing plate 423 will move along with the conductive section 311. The fixing plate 423 will pull the pull rope structure 42 to move. The pull rope structure 42 moves in the pulley 45 and multiple fixing rings 44, thereby causing the lifting section 424 to pull the sliding rod 522 upward, so that the charging socket is exposed, allowing the plug assembly 13 of the AGV laser navigation transport vehicle 10 to be accurately inserted into the charging socket. After the sliding rod 522 rises, it will push against the expansion block 54. When the plug assembly 13 is inserted into the charging socket, the circuit is turned on, the second electromagnet 521 is energized, and attracts the second magnet 16. At the same time, the second electromagnet 521 is located directly above the slot 18. Since the second magnet 16 is fixed in the slot 18, the second electromagnet 521 will pull the pull rope structure 42 downward, making the pull rope structure 42 taut. The pull rope structure 42 has a certain degree of tensile strength, and the second electromagnet 521 will be locked in the slot 18 and fit against the second magnet 16, preventing the AGV laser navigation transport vehicle 10 from being collided with during charging, which would affect the charging process.By setting the expansion block 54, after the plug assembly 13 of the AGV laser-guided transport vehicle 10 is accurately inserted into the charging socket for a period of time, heat will be generated in the charging part and the bottom of the side wall of the charging pile 20. The bottom of the side wall of the charging pile 20 and the sliding body 53 are made of metal thermally conductive material, which can effectively transfer the heat to the expansion block 54. The expansion block 54 expands due to heat, moving the push cover 52 toward the locking groove 18, so that the second electromagnet 521 and the second magnet 16 fit more tightly. During charging, the AGV laser-guided transport vehicle 10 is not affected by collisions. The present invention has a clever structure that can effectively guide the AGV laser-guided transport vehicle 10 to charge, and during charging, it makes the connection between the AGV laser-guided transport vehicle 10 and the charging pile 20 tighter, preventing the AGV laser-guided transport vehicle 10 from being affected by collisions during charging.
