Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a high-power wireless charging station for large AGV transport vehicles. Background Technology

[0002] With the rapid development of intelligent manufacturing and industrial automation, AGVs (Automated Guided Vehicles) are increasingly widely used in warehousing, logistics, and manufacturing. Large AGVs, due to their high-efficiency heavy-duty capabilities, have become core equipment for logistics transfer. However, positioning issues during charging severely restrict their operational efficiency and reliability. Existing AGV wireless charging technologies largely rely on the AGV's autonomous navigation to complete charging docking. However, due to factors such as running path errors, differences in ground flatness, and environmental interference, AGVs are prone to positioning deviations when entering charging stations. This leads to inaccurate alignment of the charging interface, reducing charging efficiency and potentially causing problems such as poor contact and equipment wear. Utility Model Content

[0003] To overcome the shortcomings of insufficient positioning accuracy during AGV charging, the technical problem of this utility model is to provide a high-power wireless charging station for large AGV transport vehicles that has auxiliary AGV charging positioning.

[0004] The technical implementation scheme of this utility model is as follows: a high-power wireless charging station for large AGV transport vehicles, including a base, a wireless charging station fixedly connected to the left side of the base, a cylinder fixedly connected inside the base, a connecting plate fixedly connected to the piston rod of the cylinder, a tension plate fixedly connected to the top of the connecting plate, and both the connecting plate and the tension plate being slidably connected to the base. The cylinder is used to drive the connecting plate and the tension plate to slide on the base. A mounting base is fixedly installed above the base, and has a groove inside, the groove corresponding to the movement path of the tension plate. Two slide rails are provided in the front-rear direction inside the mounting base, with the rear slide rail located behind and above the front slide rail. In this mounting base, a motor A is fixedly connected to the left side, and a gear A is fixedly connected to the output shaft of the motor A. A clamping block A is slidably connected in the rear slide rail, and the clamping block A has a rack. The clamping block A meshes with the gear A through the rack. A motor B is fixedly connected to the right side of the mounting base, and a gear B is fixedly connected to the output shaft of the motor B. A clamping block B is slidably connected in the front slide rail, and the clamping block B has a rack. The clamping block B meshes with the gear B through the rack. By simultaneously driving the gears A and B to rotate, the clamping blocks A and B move towards each other towards the center of the mounting base, thereby completing the auxiliary positioning for charging the AGV.

[0005] Furthermore, it also includes a protective cover. The side of the wireless charging station is fixedly connected to the protective cover. The protective cover integrates an electric push rod and an electromagnetic shield. The top of the electric push rod is fixedly connected to the electromagnetic shield. The electric push rod can drive the electromagnetic shield to rise and fall, thereby achieving electromagnetic interference protection in the charging area.

[0006] Furthermore, it also includes a fixing pad, which is fixedly connected to the stretch plate.

[0007] Furthermore, it also includes a telescopic belt, one end of which is fixedly connected to the groove of the base, and the other end of which is fixedly connected to the tension plate.

[0008] Furthermore, it also includes a lighting lamp, which is fixedly connected to the front end of the mounting base.

[0009] Furthermore, it also includes spring pads, with spring pads fixedly connected to clamping block A and clamping block B respectively.

[0010] This invention has the following advantages: By driving gears A and B through motors A and B, clamping blocks A and B move towards each other along the slide rail. After clamping the AGV transport vehicle, the stretching plate, clamping block A, and clamping block B move synchronously and are pulled towards the wireless charging station for charging. This solves the problem of insufficient positioning accuracy for AGV charging in existing systems, and achieves adaptive clamping of the AGV, reducing wear and tear on the charging port and extending the service life of the device.

[0011] A protective cover is fixedly connected to the side of the wireless charging station. An electric push rod is fixedly connected inside the protective cover. An electromagnetic shield is fixedly connected to the top of the electric push rod, which serves the functions of position control and physical protection, thereby suppressing electromagnetic interference and protecting the equipment.

Detailed Implementation

[0016] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] Example: A high-power wireless charging station for large AGV transport vehicles, such as Figure 1-3 As shown, the system includes a base 1, a wireless charging station 2, a mounting base 3, a cylinder 4, a connecting plate 5, a tension plate 6, a motor A7, a gear A8, a rack A, a motor B10, a gear B11, a rack B, a clamping block A9, and a clamping block B12. The wireless charging station 2 is fixedly connected to the left side of the base 1. The cylinder 4 is fixedly connected inside the base 1. The piston rod of the cylinder 4 is fixedly connected to the connecting plate 5. The tension plate 6 is fixedly connected to the top of the connecting plate 5, and both the connecting plate 5 and the tension plate 6 are slidably connected to the base 1. The cylinder 4 is used to drive the connecting plate 5 and the tension plate 6 to slide on the base 1. The mounting base 3 is fixedly installed above the base 1 and has a groove inside. The groove corresponds to the movement path of the stretching plate 6. Two slide rails are provided in the front-to-back direction inside the mounting base 3. The rear slide rail is located above and behind the front slide rail. The motor A7 is fixedly connected to the left side of the mounting base 3. The gear A8 is fixedly connected to the output shaft of the motor A7. The clamping block A9 is slidably connected in the rear slide rail. The clamping block A9 is provided with a rack. The clamping block A9 meshes with the gear A8 through the rack. The motor B10 is fixedly connected to the right side of the mounting base 3. The gear B11 is fixedly connected to the output shaft of the motor B10. The clamping block B12 is slidably connected in the front slide rail. The clamping block B12 is provided with a rack. The clamping block B12 meshes with the gear B11 through the rack.

[0018] When the AGV needs charging, it will automatically identify and move onto the base 1. After the AGV arrives at the base 1, the wireless charging station 2 triggers the cylinder 4 to start, which in turn drives the tension plate 6 to slide along the groove of the base 1 via the connecting plate 5 until it completes inductive calibration docking with the charging interface at the bottom of the AGV. Subsequently, the high-power wireless charging station 2 automatically identifies the AGV, and the motors A7 and B on both sides of the mounting base 3 drive the gears A8 and B to rotate, which in turn drive the clamping blocks A9 and B to move towards each other along the slide rail via the rack, achieving adaptive clamping of the AGV. After clamping the AGV, the tension plate 6, the clamping block A9, and the clamping block B12 move synchronously, pulling it towards the wireless charging station 2 for charging. After charging is complete, the clamping blocks move in the opposite direction to release the AGV, and the tension plate 6 returns to its initial position, awaiting the next charging task, thus achieving precise guidance and cyclical operation.

[0019] like Figure 1 and 3 As shown, it also includes a protective cover 13, an electric push rod 14, and an electromagnetic shield 15. The protective cover 13 is fixedly connected to the side of the wireless charging station 2. The electric push rod 14 and the electromagnetic shield 15 are integrated inside the protective cover 13. The electromagnetic shield 15 is fixedly connected to the top of the electric push rod 14. The electric push rod 14 can drive the electromagnetic shield 15 to rise and fall.

[0020] Because the wireless charging system of the wireless charging station 2 may interfere with surrounding electronic devices and is itself susceptible to external interference, an electromagnetic shielding device needs to be added to the wireless charging station 2. When the wireless charging station 2 starts charging, the electric push rod 14 simultaneously raises the electromagnetic shield 15, generating a reverse electromagnetic field to cancel out interference in the charging area. The electric push rod 14 retracts after a preset time period, hiding the shield inside the protective cover 13 to prevent damage from external forces. Furthermore, the electric push rod 14 is installed inside the protective cover 13, which provides protection for the electric push rod 14, preventing damage to it.

[0021] like Figure 1 As shown, it also includes a spring pad 16, and the spring pad 16 is fixedly connected to the clamping block A9 and the clamping block B12 respectively.

[0022] The clamping block A9 and the clamping block B12 are provided with rubber spring pads 16, which can adapt to the AGV contour error. When the clamping blocks clamp quickly, the spring pads 16 absorb the clamping impact force through elastic deformation, avoid rigid collisions that could damage the workpiece or clamping mechanism, ensure non-destructive clamping of equipment of different sizes, and achieve the effect of protecting the surface of the components.

[0023] like Figure 1As shown, it also includes a lighting lamp 17, which is fixedly connected to the front end of the mounting base 3.

[0024] The front end of the mounting base 3 is equipped with the lighting lamp 17, which automatically turns on when the AGV approaches to provide lighting and assist in nighttime charging and positioning. During equipment installation or maintenance, the brightness can be manually adjusted to illuminate the internal structure of the base 1, avoiding human errors such as missing screws or incorrect wiring due to insufficient light, thus improving maintenance efficiency.

[0025] like Figure 1 As shown, it also includes a telescopic belt 18. One end of the telescopic belt 18 is fixedly connected to the groove of the base 1, and the other end of the telescopic belt 18 is fixedly connected to the tension plate 6.

[0026] The highly elastic telescopic belt 18 is fixed to the groove sidewall of the base 1 by a buckle, and its free end is hinged to the tension plate 6. When the tension plate 6 slides, the telescopic belt 18 automatically extends or retracts, completely covering the groove gap to prevent dust and other contaminants from entering, thus achieving a protective and isolating effect.

[0027] like Figure 1 As shown, it also includes a fixing pad 19, which is fixedly connected to the tension plate 6.

[0028] The wedge-shaped rubber fixing pad 19 is embedded on the surface of the stretch plate 6. By increasing the friction of the contact surface, it ensures that the AGV remains stable during movement, while avoiding surface indentations caused by rigid contact. It plays a role in positioning and anti-slip, and achieves the effect of protecting the fixed object.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
