Description

Technical Field

[0001] This utility model belongs to the field of vehicle equipment technology, and in particular relates to a flexible intelligent charging station adapted to AGVs. Background Technology

[0002] To achieve high utilization rates for Automated Guided Vehicles (AGVs), ensuring effective charging is crucial. Therefore, AGV drive batteries and battery charging have become popular research areas. With continuous breakthroughs in high-power battery technology and innovations in charging technology, rapid charging of high-power batteries is now possible. Fast charging technology eliminates the need for AGVs to occupy specific areas for extended charging periods. Battery charging devices can be installed anywhere within the entire production system where AGVs are permitted to dock (such as segmented transport areas, turning areas, loading and stopping areas, etc.), enabling charging to be completed without removing the AGVs from the production line.

[0003] However, during the current AGV fast charging process, the following problems still exist when the AGV arrives at the automatic charging position: AGV stop position deviation and misalignment; lack of a flared design at the AGV tail end connector; mechanical wear and deformation of the AGV tail end connector, etc. These problems prevent the AGV from properly connecting to the charging interface, affecting its normal charging use. Existing intelligent charging stations require a certain amount of mutual support, which puts significant pressure on the wheels during use. Insufficient cushioning can easily damage the casters, affecting work and, in severe cases, threatening personal safety.

Figure 1 , Figure 2 As shown, it includes: a smart charger 1, a first tail plug 2 disposed inside the smart charger, the front part of the first tail plug being inserted into the tail plug flare 3, and a second tail plug 4 installed at the end of the vehicle, the connecting part of the second tail plug 4 being snapped into the tail plug flare 3; as shown Figure 3 The intelligent charger includes a housing 6, a charging module 9, a telescopic floating mechanism 5, a button 11, a waterproof connector 12, a leakage protection switch 13, a fan 14, and a handle 15. The first tail plug passes through a sliding door 10 on one side of the housing and is connected to the second tail plug 4. The housing has a cuboid structure, and four support bases 16 are provided at the bottom of the housing. A light 7 and a human-machine interface 8 are installed on the top of the housing. A trolley position detection module is installed above the housing 6. The charging module 9 and the telescopic floating mechanism 5 connected to the charging module 9 are installed inside the housing. The telescopic floating mechanism 5 is detachably connected to the first tail plug 2. When the trolley position detection module detects that the trolley has entered the charging position, the trolley moves laterally. The second tail plug 4 at the end of the trolley is guided by the tail plug horn 3 and the telescopic floating mechanism 5 is stretched up and down by the upper and lower tension springs. The left and right floating is achieved by the left and right floating linear guide rails 18, left and right floating plates 20, left and right transition floating plates 30, left and right floating spring fixing seats 32, and left and right floating springs 33. The system automatically adjusts the docking position and inserts the first tail plug 2 of the charging device, ensuring that the second tail plug (cart end) and the first tail plug (charger end) do not misalign and fail to dock. The telescopic floating mechanism is mounted on a high-precision linear guide rail and slider, allowing for flexible floating and low resistance.

[0017] Preferred, such as Figure 4 , Figure 5 As shown, the telescopic floating mechanism 5 includes: a base 17 fixed to the housing, a front and rear floating assembly installed on the base 17, a left and right floating assembly movably connected to the front and rear floating assembly, the front and rear floating assembly being perpendicular to the left and right floating assembly, and an up and down floating assembly movably connected to the left and right floating assembly, the up and down floating assembly being perpendicular to the left and right floating assembly. The front and rear floating components include front and rear floating linear guide rails 26 with limit plates 31 on both sides. The limit plates 31 are fixedly installed on the upper part of the base 17 by fasteners. One end of the front and rear floating tension spring 25 is connected to the base 17 and the other end is connected to the bottom plate of the front and rear floating plate 19. Front and rear sliders are installed on the lower side of the bottom plate of the front and rear floating plate 19.

[0018] Preferably, the upper and lower floating assembly includes upper and lower floating plates 21 mounted on the left and right floating plates 20. Upper and lower tension springs 23 connect the left and right floating plates 20 and the upper and lower floating plates 21. An upper angle swing spring 29 is mounted on one side of the left and right floating plates 20, positioned between two fixed protrusions of the left and right floating plates 20. A guide shaft support 22 passing through the left and right floating plates 20 is connected to the angle swing spring 29. The guide shaft support 22 is connected to a linear bearing 28 via a guide shaft 27 held by the guide shaft support. The linear bearing 28 is fixed to the tail socket 24, and the upper and lower floating plates are placed inside the tail socket 24. One end of the upper and lower tension spring 23 is connected to both sides of the top plate of the left and right floating plates 20, and the other end of the upper and lower tension spring 23 is connected to both ends of the upper and lower floating plates 21. During charging, if the second tail plug 4 of the vehicle body is not parallel to or misaligned with the first tail plug 2 of the smart charger, the angle swing and upper and lower floating parts are aligned with the first tail plug 4 by the angle swing spring 29.

[0019] This intelligent charging station uses a high-frequency switching power supply module. The charging function is controlled via a human-machine interface through the 485 communication interface of the first tail plug, fulfilling the automatic charging function of the AGV vehicle. The second tail plug has an adjustable height of 220mm from the ground (±20mm), which effectively increases the floating range of the tail plug's docking position. This ensures good reliability even when operating under unstable or error-prone conditions. Its vertically floating spring structure accurately docks the plug, coping with uneven ground or minor errors.

[0020] In the event that the center height of the first tail plug 2 is deviated or not parallel, the tail plug horn 3 of the trolley guides the movement, and the upper and lower tension springs 23 and the front and rear floating tension springs 25 of the telescopic floating mechanism drive the left and right floating transition plate 30 to float left and right, and the angle swing spring 29 to adjust the angle, so as to automatically adjust the docking position and ensure that the second tail plug 4 (trolley end) and the first tail plug 2 (charger end) do not have errors that cause them to fail to dock.

[0021] Preferred, such as Figure 5As shown, the tail plug horn 3 is horn-shaped and has a guiding function, guiding the first tail plug 2 (charger end) to be inserted into the second tail plug 4 (cart end) for charging; the first interface of the tail plug horn 3 matches the front part of the first tail plug 2, and the second interface of the tail plug horn 3 matches the connecting part of the second tail plug 4.

[0022] Preferably, the telescopic floating mechanism 5 is equipped with front and rear floating tension springs 25, left and right, and up and down tension springs 23 to adjust the angle of the tension springs, and has front and rear, left and right, and up and down floating functions to automatically adjust the docking position.

[0023] Preferably, the first and second tail plugs are made of copper-carbon alloy.

[0024] Preferably, the upper and lower tension springs 23, the front and rear floating tension springs 25, and the angle swing springs 29 are all made of 65Mn material.

[0025] Preferably, the left and right floating linear guide rails 18 and the front and rear floating linear guide rails 26 are made of GCr15 material.

[0026] Not only does it have the function of connecting or disconnecting the main circuit, just like other circuit breakers, but it also has the function of detecting and judging leakage current. When leakage or insulation failure occurs in the main circuit, the leakage protection switch can connect or disconnect the main circuit according to the judgment result.

[0027] This utility model embodiment features an automatic charging device designed at an automatic charging station. This device enables the automated guided vehicle (AGV) to automatically dock with the charging port upon arrival at the charging location. The AGV automatically charges at the charging station, completing a self-check within a short time (3 seconds) after power is connected, maintaining a charging standby state, reducing tedious manual operations and improving work efficiency. Once the AGV and the charger's first tail plug make contact, the charger can be started and stopped via the 485 communication serial port on the first tail plug, and the charger's status information can be obtained. The intelligent charger detects a parameter of 5-30V (the parameter can be set according to actual needs), indicating battery contact and initiating charging. When the internal voltage rises to match the battery voltage, the output relay opens for charging. When the AGV does not need charging, the AGV control relay disconnects the tail plug dry contact, and the AGV waits 3 seconds before leaving. Once charging is complete, the charger automatically stops charging.

[0028] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
