Abstract
Description
Technical Field
[0001] This utility model relates to the field of AGV vehicle charging pile technology, specifically an automatic plug-in charging device. Background Technology
[0002] An AGV charging station is a charging device specifically designed for automated guided vehicles (AGVs). It allows AGV robots to automatically or manually return to the charging station for charging when their power is low, ensuring that the AGV robots can continue to work.
[0003] Most existing AGV vehicle charging stations have their charging heads located inside the charging station. Since the charging station needs to automatically extend the charging head to connect with the AGV vehicle's charging port, the extension distance of the charging head located inside the charging station is limited.
[0004] For example, the AGV charging pile structure proposed in document number "CN218577542U" has its charging head located inside the AGV charging pile structure. Not only is its extension length limited, but the charging head also needs to extend and retract multiple times, making it a vulnerable component for the charging pile. Furthermore, its internal location makes maintenance inconvenient. Therefore, we propose an automatic plug-and-play charging device. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides an automatic plug-in charging device, which has the advantages of setting the electrodes outside the charging cabinet for easy maintenance, and achieving long-distance extension under the drive of the transmission screw, thus solving the problems mentioned in the prior art.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic plug-in charging device, including a charging cabinet, a cabinet door rotatably connected to one side of the charging cabinet, a charging control component inside the charging cabinet, support legs at the four corners of the bottom of the charging cabinet, and an installation platform below the charging cabinet, the installation platform being connected to the support legs.
[0007] The installation platform is equipped with an electric telescopic frame, and the top of the free end of the electric telescopic frame is equipped with a strip box, one end of which extends to the outside of the electric telescopic frame.
[0008] Two electrodes are installed inside the bar box, both of which extend outside the bar box. The electrodes are connected to the charging control component via a charging cable, and the electric telescopic frame is electrically connected to the charging control component.
[0009] Preferably, the charging control component includes a charging control board and a current protector, with the charging control board connected to the charging cable via a current sensor.
[0010] Preferably, the installation platform includes a mounting base, and the four corners of the mounting base are connected to the support legs via connecting brackets.
[0011] Preferably, the electric telescopic frame includes two strip supports symmetrically installed on the top of the mounting base, a transmission screw is provided between the two strip supports, both ends of the transmission screw are rotatably mounted in bearing seats, the bearing seats are fixed to the mounting base, one end of the transmission screw is connected to the drive device, and the drive device is electrically connected to the charging control board.
[0012] The mounting base has a strip plate on top, and connecting plates are connected to both sides of the strip plate. The strip support is located between the two connecting plates, and each strip support has a guide rail connected to the connecting plate on its side.
[0013] The transmission screw is threaded with a nut, which is connected to the end of the strip plate near the drive device, while the strip box is installed on the top of the strip plate away from the drive device.
[0014] Preferably, the charging control board is also electrically connected to the display screen and operation buttons, which are located on the surface of the charging cabinet.
[0015] Preferably, the charging cabinet has a vertically downward mounting plate inside, the charging control components are mounted on the mounting plate, and at least two mounting brackets are mounted on the side of the mounting plate, with both ends of the mounting brackets being detachably connected to the inner wall of the charging cabinet.

[0017] Preferably, the charging cabinet below the mounting plate is provided with an air inlet, and the top side of the charging cabinet is provided with an exhaust vent, which is equipped with an exhaust fan and is electrically connected to the charging control board.
[0018] Compared with the prior art, in use, the strip plate can extend to the outside of one end of the mounting base under the drive of the nut. The extension length of the strip plate is almost equal to the length of the mounting base. The strip plate is supported by two guide rails, so the strip plate not only has a long extension length, but also good support. The electrode used to connect with the AGV vehicle is set in the strip box, which is installed on the end of the strip plate, so that the electrode can extend a long distance.
[0019] Moreover, the electrodes are located at the bottom of the charging cabinet and are fully exposed, rather than inside the charging cabinet.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1 to 6 This utility model provides a technical solution: an automatic plug-in charging device, including a charging cabinet 1, a cabinet door 6 rotatably connected to one side of the charging cabinet 1, the cabinet door 6 being connected to the charging cabinet 1 by a hidden lock, and the inside of the charging cabinet 1 can be inspected after opening the cabinet door 6, and the charging cabinet 1 is provided with support legs 7 at the four corners of the bottom of the charging cabinet 1, and the support legs are set on the ground.
[0029] The charging cabinet 1 has a vertically downward mounting plate 20. The charging control components are mounted on the mounting plate 20. At least two mounting brackets 26 are mounted on the side of the mounting plate 20. The two ends of the mounting brackets 26 are detachably connected to the inner wall of the charging cabinet 1. Specifically, fixing plates (such as...) are set at both ends of the mounting brackets 26. Figure 4 (As indicated by arrow A in the middle), the fixing plate is fastened to the inner wall of the charging cabinet 1 with bolts;
[0030] The charging cabinet 1 houses a charging control assembly, specifically mounted on a mounting plate 20. This assembly includes a charging control board 17 and a current protector 18, both mounted on the mounting plate 20. The charging control board 17 and current protector 18 are connected by wires. The charging control board 17 is connected to the mains power supply via a power cord. A current sensor 27 is also mounted on the mounting plate 20. A charging cable 15 is connected to the output of the current protector 18, passing through the bottom of the charging cabinet 1 and positioned within the current sensor 27. In practical operation, the other end of the charging cable 15 is connected to two electrodes 9. The electrodes 9 are then connected to the AGV vehicle for charging. The current within the charging cable 15 is monitored by the current sensor 27, and the current protector 18 automatically trips and cuts off power in cases of excessive charging current or leakage.
[0031] The charging cabinet 1 is provided with an installation platform 24 below. The specific structure of the installation platform 24 includes a mounting base 12. The four corners of the mounting base 12 are connected to the support legs 7 through connecting brackets 2. There is a certain gap between the installation platform 24 and the bottom of the charging cabinet 1.
[0032] The mounting base 12 is provided with an electric telescopic frame 25. The specific structure of the electric telescopic frame 25 includes two strip supports 14 symmetrically installed on the top of the mounting base 12. A transmission screw 21 is provided between the two strip supports 14. Both ends of the transmission screw 21 are rotatably set in the bearing seats 22. The bottom of the bearing seats 22 is fixed on the mounting base 12. One end of the transmission screw 21 is connected to the drive device 10.
[0033] A strip plate 5 is provided above the mounting base 12. Connecting plates 11 are connected to both sides of the strip plate 5. The strip support 14 is located between the two connecting plates 11, and each strip support 14 has a guide rail 16 connected to the connecting plate 11 on its side.
[0034] The transmission screw 21 is threaded with a nut 23, which is connected to the end of the strip plate 5 near the drive device 10. The drive device 10 is a motor and a reducer mounted on the mounting base 12. The motor is connected to one end of the transmission screw 21 through the reducer. So when the motor rotates, it can drive the transmission screw 21 to rotate. The transmission screw 21 drives the nut 23 to reciprocate, thereby allowing the nut 23 to drive the strip plate 5 to reciprocate along the guide rail 16.
[0035] like Figure 5 and Figure 6 As shown, driven by the nut 23, the strip plate 5 can extend to the outside of one end of the mounting base 12. The extension length of the strip plate 5 is almost equal to the length of the mounting base 12, and the strip plate 5 is supported by two guide rails 16. Therefore, the strip plate 5 not only has a long extension length but also good support, enabling stable operation when the strip plate 5 extends or shortens. Figure 5 As shown, two electrodes 9 are installed inside a strip box 8, which is an insulator. The strip box 8 is installed at the top of the strip plate 5 away from the drive device 10. One end of the strip box 8 extends to the outside of the strip plate 5, and the two electrodes 9 protrude from the end of the strip box 8.
[0036] Specifically, the installation height and position of the two electrodes 9 correspond to the charging port of the AGV vehicle. When the AGV vehicle stops in the preset charging position, the bar box 8 extends forward under the action of the bar plate 5, allowing the bar box 8 to drive the two electrodes 9 into the charging port, realizing circuit connection and charging the AGV vehicle. The charging current is monitored by the current sensor 27. As the battery capacity of the AGV vehicle decreases, the charging current also decreases. When the current decreases to the preset value, the bar plate 5 retracts under the action of the transmission screw 21, thereby allowing the two electrodes 9 to be pulled out of the charging port.
[0037] Furthermore, such as Figure 1 As shown, the surface of the charging cabinet 1 is equipped with a display screen 4 and operation buttons. Figure 3 As shown, the charging cabinet 1 below the mounting plate 20 is provided with an air inlet 19, and an exhaust vent 13 is provided on the top side of the charging cabinet 1. An exhaust fan is provided inside the exhaust vent 13. The drive device 10 (motor), the exhaust fan, the display screen 4, and the operation buttons are electrically connected to the charging control board 17. The electrical connection is specifically achieved through wires and signal lines, thereby realizing the transmission of electrical energy and signals.
[0038] The exhaust fan can continuously exhaust air outwards, while outside air continuously enters through the air inlet 19, allowing cool air to pass over the surface of the mounting plate 20, thereby carrying away the heat from the surface of the mounting plate 20. A temperature sensor can also be installed on the mounting plate 20, and the temperature sensor is connected to the charging control board 17 via a wire. When the temperature reaches the preset value, the charging control board 17 automatically controls the exhaust fan to rotate.
[0039] Based on the above embodiments, further optimization can be achieved by providing an alarm 3 on the top of the charging cabinet 1. The alarm 3 is an audible and visual alarm and is connected to the charging control board 17 via wires. When the battery is fully charged or the circuit breaker trips, the alarm can be activated.
