Description

Technical Field

[0001] This utility model relates to the field of automated guided vehicle technology, and in particular to a wireless charging structure for an AGV transport vehicle. Background Technology

[0002] With the rapid development of intelligent manufacturing and warehouse automation, AGV (Automated Guided Vehicle) transport carts, as core equipment for material transfer, have their endurance and charging efficiency directly affecting the continuity of production operations. To solve the problems of traditional wired charging requiring manual plugging and unplugging, fixed charging positions, and affecting the flexibility of AGV scheduling, wireless charging structures for AGV transport carts have emerged.

[0003] However, when the transmitting coil of a traditional AGV transport vehicle wireless charging structure is exposed to the environment in a non-charging state, foreign objects such as dust and oil, which are common in industrial scenarios, tend to adhere to the coil surface and gradually accumulate, affecting the coil's coupling effect. For example, aluminum alloy dust is generated during the processing of parts in the workshop, and the workshop ventilation system cannot completely remove this dust. When not charging, the transmitting coil of the charging pile is exposed for a long time, and dust gradually accumulates on the surface of the coil. This causes a dense dust layer to form on the aluminum alloy surface of the transmitting coil, which reduces the effective coupling area between the transmitting coil and the AGV receiving coil, affecting the power transmission efficiency. Utility Model Content

[0004] This utility model discloses a wireless charging structure for AGV transport vehicles, aiming to solve the technical problem that when the transmitting coil of a traditional AGV transport vehicle is exposed to the environment in a non-charging state, foreign objects such as dust and oil stains, which are common in industrial scenarios, tend to adhere to the coil surface and gradually accumulate, affecting the coil coupling effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wireless charging structure for an AGV (Automated Guided Vehicle) transport vehicle includes a charging pile, a transmitting coil connected to one outer wall of the charging pile, and a dustproof mechanism: the dustproof mechanism includes a connecting seat connected to one outer wall of the charging pile, the transmitting coil disposed on the inner wall of the connecting seat, a motor connected to one outer wall of the connecting seat, a first gear connected to the output end of the motor, two symmetrically distributed fixing blocks connected to one outer wall of the charging pile, two symmetrically distributed fixing seats connected to one outer wall of the charging pile, a second gear disposed on the inner wall of one fixing seat, the second gear meshing with the first gear, a first connecting plate connected to the opposite outer wall of the fixing blocks and the fixing seats, a fixing groove provided on one outer wall of the charging pile, the first connecting plate connected to the inner wall of the fixing groove, a dust cover connected to the outer wall of the first connecting plate near the charging pile, a second connecting plate connected to the outer wall of the dust cover, and the second connecting plate connected to the inner wall of the fixing groove; and a quick-release mechanism: the quick-release mechanism is located on one inner wall of the charging pile.

[0006] By adopting the above technical solution, the dustproof mechanism includes a connecting seat connected to the outer wall of one side of the charging pile. The inner wall of the connecting seat is provided with a transmitting coil, which is used to transmit electrical energy to the receiving coil of the AGV transport vehicle through electromagnetic induction. At this time, a motor is connected to the outer wall of one side of the connecting seat. The output end of the motor is connected to a first gear. The first gear is used to transmit the power of the motor to a second gear that meshes with it. The second gear is used to drive the first connecting plate to move. At this time, a fixed seat connected to the outer wall of one side of the charging pile provides installation space for the second gear set on its inner wall. At this time, the same first connecting plate is connected to the outer wall of the fixed block and the fixed seat on opposite sides. The first connecting plate is used to drive the dust cover connected to the outer wall of one side of it to unfold or fold. The dust cover is used to cover the transmitting coil in the non-charging state to prevent dust from entering. At this time, a second connecting plate is connected to the outer wall of one side of the dust cover. The second connecting plate is used to enhance the stability of the connection between the dust cover and the fixed groove. At the same time, the fixed groove set on the outer wall of one side of the charging pile accommodates the first connecting plate and the second connecting plate and defines their installation positions.

[0007] As a further embodiment of this utility model: the quick-release mechanism includes two symmetrically distributed limiting plates connected to one side of the outer wall of the charging pile. Two symmetrically distributed telescopic rods are connected to one side of the outer wall of the limiting plate. A limiting spring is sleeved on the outer wall of the telescopic rod. A locking block is connected to the other side of the outer wall of the limiting plate. One side of the outer wall of the two locking blocks is connected to the outer wall of the same transmitting coil. Connecting grooves are provided on both sides of the outer wall of the transmitting coil. Two symmetrically distributed connecting blocks are connected to the outer wall of the transmitting coil near the charging pile.

[0008] By adopting the above technical solution, the quick-release mechanism includes two symmetrically distributed limiting plates connected to the outer wall of one side of the charging pile. The limiting plates provide the mounting base for two telescopic rods and two locking blocks connected to the outer wall of one side. At this time, a limiting spring is sleeved on the outer wall of the telescopic rod. The limiting spring provides a restoring force for the telescopic rod through its own elastic deformation, thereby enabling the locking block connected to the outer wall of the other side of the limiting plate to be locked into the outer wall of the transmitting coil, thereby realizing the quick fixing and disassembly of the transmitting coil and reducing the disassembly and assembly time. At this time, the outer walls of both sides of the transmitting coil are provided with connecting grooves, which provide a suitable embedding space for the locking blocks. At this time, two symmetrically distributed connecting blocks are connected to the outer wall of the transmitting coil near the charging pile. The connecting blocks are used to assist in positioning the relative position of the transmitting coil and the charging pile, which facilitates quick alignment and installation.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. To prevent dust from adhering to the surface of the transmitting coil when the charging pile is not in use, thereby affecting the coupling effect of the coil, in the non-charging state, the motor drives the first connecting plate to move through the transmission of the first gear and the second gear, so that the dust cover connected to the outer wall of one side of the first connecting plate unfolds and completely covers the transmitting coil. The dust cover, together with the connecting seat, forms a closed protection for the transmitting coil, which can prevent external dust from directly contacting the coil surface, thereby maintaining the cleanliness of the transmitting coil surface and ensuring the stability of its electromagnetic induction environment with the AGV receiving coil.

[0010] 2. Facilitates maintenance of the transmitting coil. The limiting plate provides a stable mounting base for the telescopic rod and the locking block. The limiting spring sleeved on the outer wall of the telescopic rod then uses its elastic deformation to provide a restoring force to the locking block connected to the outer wall of the limiting plate on the other side. This allows the locking block to quickly engage or disengage from the connecting slots on both sides of the transmitting coil. Disassembly and re-fixing can be completed by pushing or pulling the limiting plate connected to the outer walls of both sides of the transmitting coil with external force. This avoids the tedious operation of disassembling each bolt individually, which is required for traditional bolt connections, and reduces the complexity of maintenance operations.

[0019] Reference Figure 1 , Figure 2 and Figure 3 A wireless charging structure for an AGV (Automated Guided Vehicle) transport vehicle includes a charging pile 1, with a transmitting coil 3 connected to one outer wall of the charging pile 1. It also includes a dustproof mechanism: the dustproof mechanism includes a connecting seat 2 connected to one outer wall of the charging pile 1, the transmitting coil 3 disposed on the inner wall of the connecting seat 2, a motor 5 connected to one outer wall of the connecting seat 2, the output end of the motor 5 connected to a first gear 6, two symmetrically distributed fixing blocks 8 connected to one outer wall of the charging pile 1, and two symmetrically distributed fixing seats 9 connected to one outer wall of the charging pile 1, one of the fixing seats 9 having an inner... The wall is provided with a second gear 7, which meshes with the first gear 6. The outer walls of the fixing block 8 and the fixing seat 9 on opposite sides are connected to the same first connecting plate 10. The outer wall of the charging pile 1 on one side is provided with a fixing groove 12. The first connecting plate 10 is connected to the inner wall of the fixing groove 12. The outer wall of the first connecting plate 10 near the charging pile 1 is connected to a dust cover 11. The outer wall of the dust cover 11 on one side is connected to a second connecting plate 13. The second connecting plate 13 is connected to the inner wall of the fixing groove 12 on one side. Quick release mechanism: The quick release mechanism is located on the inner wall of the charging pile 1 on one side.

[0020] Specifically, the dustproof mechanism includes a connecting seat 2 connected to the outer wall of one side of the charging pile 1. A transmitting coil 3 is installed on the inner wall of the connecting seat 2. The transmitting coil 3 transmits electrical energy to the receiving coil of the AGV transport vehicle via electromagnetic induction. A motor 5 is connected to the outer wall of one side of the connecting seat 2. The output end of the motor 5 is connected to a first gear 6. The first gear 6 transmits the power of the motor 5 to a second gear 7 that meshes with it. The second gear 7 drives the first connecting plate 10 to move. A fixed seat 9 connected to the outer wall of one side of the charging pile 1 provides installation space for the second gear 7, which is located on its inner wall. At this time, the same first connecting plate 10 is connected to the outer wall of the opposite side of the fixing block 8 and the fixing seat 9. The first connecting plate 10 is used to drive the dust cover 11 connected to its outer wall to unfold or fold. The dust cover 11 is used to cover the transmitting coil 3 in the non-charging state to prevent dust from entering. At this time, a second connecting plate 13 is connected to the outer wall of the dust cover 11. The second connecting plate 13 is used to enhance the stability of the connection between the dust cover 11 and the fixing groove 12. At the same time, the fixing groove 12 set on the outer wall of the charging pile 1 accommodates the first connecting plate 10 and the second connecting plate 13 and limits their installation position.

[0021] The outer walls of the fixing block 8, fixing seat 9, first connecting plate 10 and second gear 7 are connected to the same connecting rod.

The connecting rod is rotatably connected to the outer walls of the second gear 7, fixing block 8 and fixing seat 9. The outer walls of the two connecting rods are fixedly connected to the same first connecting plate 10, thereby providing a pivot point for the rotation of the first connecting plate 10.

[0022] In particular, the dust cover 11 has a foldable structure. The foldable dust cover 11 can be stored in the fixing slot 12 when charging to avoid obstructing the AGV docking.

[0023] Specifically, the first connecting plate 10 has a U-shaped structure, which can avoid the installation space of the transmitting coil 3.

[0024] Reference Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, the quick-release mechanism includes two symmetrically distributed limiting plates 16 connected to one side of the outer wall of the charging pile 1. Two symmetrically distributed telescopic rods 18 are connected to one side of the outer wall of the limiting plate 16. A limiting spring 19 is sleeved on the outer wall of the telescopic rod 18. A locking block 17 is connected to the other side of the outer wall of the limiting plate 16. One side of the outer wall of the two locking blocks 17 is connected to the outer wall of the same transmitting coil 3. Connecting grooves 14 are provided on both sides of the outer wall of the transmitting coil 3. Two symmetrically distributed connecting blocks 15 are connected to the outer wall of the transmitting coil 3 near the charging pile 1.

[0025] Specifically, the quick-release mechanism includes two symmetrically distributed limiting plates 16 connected to the outer wall of one side of the charging pile 1. The limiting plates 16 provide the mounting base for two telescopic rods 18 and two locking blocks 17 connected to the outer wall of one side of the limiting plate 16. At this time, a limiting spring 19 is sleeved on the outer wall of the telescopic rod 18. The limiting spring 19 provides a restoring force for the telescopic rod 18 through its own elastic deformation, thereby enabling the locking block 17 connected to the outer wall of the other side of the limiting plate 16 to be locked into the outer wall of the transmitting coil 3, thereby realizing the quick fixing and disassembly of the transmitting coil 3 and reducing the disassembly and assembly time. At this time, the outer walls of both sides of the transmitting coil 3 are provided with connecting grooves 14, which provide a suitable embedding space for the locking block 17. At this time, two symmetrically distributed connecting blocks 15 are connected to the outer wall of the transmitting coil 3 near the charging pile 1. The connecting blocks 15 are used to assist in positioning the relative position of the transmitting coil 3 and the charging pile 1, which facilitates quick alignment and installation.

[0026] The locking block 17 is connected to the inner wall of the connecting groove 14, and the connecting groove 14 is used to fix the locking block 17.

[0027] Reference Figure 1 In a preferred embodiment, a detector 4 is connected to one outer wall of the charging pile 1, and the detector 4 is located above the transmitting coil 3.

[0028] Specifically, when the detector 4 detects that the transport trolley is approaching, it controls the motor 5 to start, thereby driving the dust cover 11 to unfold through the first connecting plate 10.

[0029] Working principle: During use, the detector 4, installed above the transmitting coil 3, monitors the position of the AGV transport vehicle in real time via infrared signals. When it detects that the AGV transport vehicle has reached a preset distance from the charging pile 1, it sends a start signal to the motor 5. At this time, the motor 5 drives the first gear 6 at its output end to rotate. The first gear 6 meshes with the second gear 7 in the fixed base 9, thereby driving the second gear 7 to rotate. Then, the connecting rod drives the first connecting plate 10 to rotate around the connection point between the fixed block 8 and the fixed base 9, so that the dust cover 11 connected to one side of the first connecting plate 10 is folded and retracted synchronously, and finally stored in the fixing slot 12 of the charging pile 1. When the dust cover 11 is completely retracted, the motor 5 receives the feedback signal from the detector 4 and stops working, completely exposing the transmitting coil 3, thus reserving coupling space for docking with the receiving coil of the AGV transport vehicle. When charging is completed, the detector 4 detects the AGV transport vehicle... After the trolley has completely driven away, a reverse start signal is sent to motor 5 again, so that motor 5 rotates in the reverse direction. At this time, the reverse meshing of the first gear 6 and the second gear 7 drives the first connecting plate 10 to rotate in the reverse direction, so that the first connecting plate 10 pushes the dust cover 11 out of the fixed groove 12 until it completely covers the transmitting coil 3 again, restoring the closed protection. Next, when the transmitting coil 3 needs maintenance, the operator pulls the limiting plate 16 on both sides of the outer wall of the transmitting coil 3, so that the locking block 17 fixed on one side of the outer wall of the limiting plate 16 disengages from the inner wall of the connecting groove 14 on both sides of the outer wall of the transmitting coil 3. When the limiting plate 16 is under force, it will push the telescopic rod 18 connected to the other side of its outer wall to retract axially, and at the same time compress the limiting spring 19 on the outer wall of the telescopic rod 18. When the locking block 17 completely disengages from the connecting groove 14 of the transmitting coil 3, the transmitting coil 3 loses its fixation and can be directly removed from the inner wall of the connecting seat 2 to complete the disassembly.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
