Existing charging piles are mostly fixed installations, which suffer from limited charging range and poor flexibility. When there are many devices to be charged or they are scattered, efficient charging is difficult to achieve. At the same time, existing mobile charging piles have low rail switching positioning accuracy, inconvenient charging docking, and lack a comprehensive intelligent management system, making it impossible to achieve precise positioning, real-time monitoring, and remote operation. This results in low charging efficiency, high maintenance costs, and difficulty in meeting the needs of large-scale, intelligent charging.

[0003] To address the aforementioned issues, this invention proposes a mobile charging pile, its positioning method, and an intelligent charging system, enabling flexible movement, precise positioning, intelligent charging, and remote control of the charging pile, thereby improving charging efficiency and ease of operation and maintenance.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-2 The present invention provides a technical solution:

[0026] A mobile charging station, its positioning method, and an intelligent charging system:

[0027] Mobile charging station structure

[0028] The mobile charging station includes a main guide rail 1 and a secondary guide rail 2, which are arranged in a cross shape to form a cross-shaped guide track, enabling the charging station to move in two vertical directions and expand the charging coverage area. An electric hoist moving structure 5 is installed on the main guide rail 1 and the secondary guide rail 2, which slides along them. The electric hoist moving structure 5 serves as the moving power component, driving the main body of the charging station to relocate.

[0029] A conversion seat 3 is installed at the junction of the main guide rail 1 and the auxiliary guide rail 2. The conversion seat 3 is used to smoothly switch the electric hoist moving structure 5 between the main guide rail 1 and the auxiliary guide rail 2, ensuring a smooth and uninterrupted switching process. Lifting connectors 4 are installed at the top of the main guide rail 1, the auxiliary guide rail 2, and the conversion seat 3. The lifting connectors 4 are used to hoist and fix the entire guide rail structure and charging pile to the installation surface, such as the ceiling or a bracket, ensuring the stability of the equipment installation while saving floor space.

[0030] A mobile charging cabinet 6 is installed at the bottom of the electric hoist's mobile structure 5. The mobile charging cabinet 6 is the core charging component, integrating an energy storage module, a charging control module, etc., to provide a stable charging power supply. The bottom of the mobile charging cabinet 6 is connected to a connecting column 25 via an electric push rod 24. A T-shaped tube 26 is installed on the side of the connecting column 25, and a charging head 27 is internally attached to one end of the T-shaped tube 26. The charging head 27 is connected to the interior of the mobile charging cabinet 6 via a wire 28 for transmitting electrical energy. The charging head 27 can be connected to the charging interface of the device to be charged to achieve power transmission. The electric push rod 24 can drive the connecting column 25 to rise and fall, thereby adjusting the height of the charging head 27 to accommodate devices of different heights and improve docking flexibility.

[0031] A positioning plate 7 is installed on the end face of the secondary guide rail 2 away from the main guide rail 1. The positioning plate 7 is a positioning component for the charging pile when it is in standby mode, and it is also used to provide power to the mobile charging cabinet 6. A conductive connection hole 9 for power supply is installed inside the positioning plate 7. A conductive connection connector 8 is installed on the side of the mobile charging cabinet 6 at the position corresponding to the conductive connection hole 9. When the charging pile is in standby mode, the conductive connection connector 8 is inserted into the conductive connection hole 9 to connect the external power supply to the mobile charging cabinet 6, charge the energy storage module of the mobile charging cabinet 6, and ensure that the equipment has continuous charging capability. An indicator light 10 is installed on the top of the positioning plate 7. The indicator light 10 is used to display the equipment status, such as standby power supply status, charging status, fault status, etc., so that the staff can quickly check the equipment operation status. A QR code pasting area 11 is set on the top of the positioning plate 7. The QR code pasting area 11 can be used to paste equipment information QR codes, calibration QR codes, etc. The equipment information QR code is used to query equipment parameters and maintenance records, and the calibration QR code is used for positioning accuracy calibration.

[0032] The mobile charging cabinet 6 has guide grooves 29 on both sides of its top. A guide plate 30 is installed on the side of the positioning plate 7 at the position corresponding to the guide groove 29. An inclined plate 31 is installed on the surface of the mobile charging cabinet 6 corresponding to the guide plate 30. When the mobile charging cabinet 6 is moved to the standby position, the guide plate 30 is embedded into the guide groove 29 under the guidance of the inclined plate 31, realizing the precise positioning of the mobile charging cabinet 6, ensuring that the conductive connection connector 8 can be accurately inserted into the conductive connection hole 9, and improving the stability during standby.

[0033] The conversion base 3 includes a guide rail 12, the top of which is connected to a rotating ring 14 via a vertical rod 13. A lifting connector 4 on the conversion base 3 is connected to the top of the rotating ring 14 via a bearing seat, allowing the rotating ring 14 to rotate flexibly, thereby driving the guide rail 12 to rotate. A toothed piece 15 is mounted on the side of the rotating ring 14. Guide rails 20 are mounted on the tops of the main guide rail 1 and the secondary guide rail 2 at positions corresponding to the toothed piece 15. A slider 21 is slidably mounted on the surface of the guide rail 20, and a rack 16 is mounted on the slider 21. The rack 16 meshes with the toothed piece 15. A connecting plate 17 is mounted on the side of the rack 16. An electrical control box 18 is mounted on the surface of the main guide rail 1, and the side of the electrical control box 18 is connected to the connecting plate 17 via an electric push rod 19. The control box 18 controls the extension and retraction of the electric push rod 19, which drives the connecting plate 17 and the slider 21 to slide along the guide rail 20, thereby driving the rack 16 to move. The rack 16 meshes with the gear plate 15, driving the rotating ring 14 and the adjusting guide rail 12 to rotate, realizing the alignment of the adjusting guide rail 12 with the main guide rail 1 or the secondary guide rail 2, and completing the guide rail switching. The bottom end of the rotating ring 14 is also equipped with a blocking plate 22 that can block the end of the main guide rail 1 or the secondary guide rail 2. When the adjusting guide rail 12 is aligned with one of the guide rails, the blocking plate 22 blocks the end of the other guide rail, preventing the electric hoist moving structure 5 from deviating from the track, and improving the safety and accuracy of guide rail switching.

[0034] Both the main guide rail 1 and the auxiliary guide rail 2 are equipped with proximity switches 23 at the top of the corresponding conversion seat 3. The proximity switches 23 are used to detect the rotational position of the adjusting guide rail 12. When the adjusting guide rail 12 is precisely aligned with the main guide rail 1 or the auxiliary guide rail 2, the proximity switches 23 send a signal to the control box 18. The control box 18 controls the electric push rod 19 to stop moving, ensuring that the guide rail switching positioning is accurate.

[0035] The specific steps for locating a mobile charging station are as follows:

[0036] The positioning method consists of three parts: guide rail movement positioning, charging docking positioning, and positioning calibration. These three parts work together to ensure the accuracy of charging pile movement and docking, thereby improving charging efficiency.

[0037] Guide rail movement positioning

[0038] The guide rail movement positioning is used to achieve smooth movement and precise positioning of the electric hoist's moving structure 5 between the main guide rail 1, the auxiliary guide rail 2, and the conversion seat 3. The specific process is as follows:

[0039] 1. Standby Positioning: When the charging pile is in standby mode, the electric hoist moving structure 5 stops at the end of the auxiliary guide rail 2 away from the main guide rail 1. The guide groove 29 of the moving charging cabinet 6 cooperates with the guide plate 30 of the positioning plate 7. The conductive connection connector 8 is inserted into the conductive connection hole 9. The indicator light 10 lights up, indicating that the equipment is in standby power supply mode. At this time, the proximity switch 23 is in the power off state.

[0040] 2. Rail Switching: When the charging pile needs to be moved to the direction of the main guide rail 1, the control box 18 receives a control command, either manually or remotely, and activates the electric push rod 19. The electric push rod 19 pushes the connecting plate 17, causing the slider 21 to slide along the guide rail 20. The rack 16 on the slider 21 meshes with the toothed plate 15 on the side of the rotating ring 14, causing the rotating ring 14 and the adjusting guide rail 12 to rotate 90°, so that the adjusting guide rail 12 is precisely aligned with the main guide rail 1. At the same time, the blocking plate 22 at the bottom of the rotating ring 14 rotates synchronously, sealing the end of the secondary guide rail 2 and preventing the electric hoist moving structure 5 from deviating from the track. When the proximity switch 23 detects the signal that the adjusting guide rail 12 is in position, it sends a signal to the control box 18. The control box 18 controls the electric push rod 19 to reset, and the rack 16 and toothed plate 15 disengage, completing the rail switching and positioning. Similarly, the alignment switching between the adjusting guide rail 12 and the secondary guide rail 2 can be achieved.

[0041] 3. Movement and Positioning: After the guide rail switching is completed, the control box 18 controls the electric hoist moving structure 5 to start and slide along the current main guide rail 1 or auxiliary guide rail 2. During the movement, the inductive position sensor on the guide rail 20 works in conjunction with the proximity switch 23 to collect the position and travel data of the electric hoist moving structure 5 in real time and feed it back to the control box 18. The control box 18 adjusts the moving speed and travel of the electric hoist moving structure 5 according to the data to ensure that it stops accurately at the designated position. The error of the guide rail movement and positioning does not exceed ±5mm.

[0042] Charging docking positioning

[0043] The charging docking positioning is used to achieve precise docking between the charging head 27 and the interface of the device to be charged, ensuring smooth charging. The specific process is as follows:

[0044] When the electric hoist moving structure 5 moves the mobile charging cabinet 6 to the vicinity of the device to be charged, the control box 18 receives the docking command and activates the electric push rod 24. The electric push rod 24 pushes the connecting column 25 downward, causing the T-shaped tube 26 and the charging head 27 to move downward synchronously until the charging head 27 is at the same horizontal level as the charging interface of the device to be charged, completing the initial height positioning. Subsequently, the control box 18 fine-tunes the position of the electric hoist moving structure 5 so that the charging head 27 at one end of the T-shaped tube 26 is aligned with the charging interface of the device to be charged. At this time, the inclined plate 31 on the guide plate 30 plays an auxiliary guiding role to prevent the charging head 27 from being misaligned during docking. After the charging head 27 is locked in place with the interface of the device to be charged, the control box 18 detects the successful docking signal through the detection module, completes the charging docking positioning, and prepares to start charging.

[0045] After charging is completed, the control box 18 controls the electric push rod 24 to retract, which drives the connecting column 25, T-tube 26 and charging head 27 to move upward and reset. Then, it controls the electric hoist moving structure 5 to move along the guide rail and return to the standby positioning position. The conductive connection connector 8 reconnects with the conductive connection hole 9, and the indicator light 10 returns to the standby state, completing the positioning reset.

[0046] Positioning calibration

[0047] To ensure positioning accuracy, the positioning components need to be calibrated regularly. The specific process is as follows: Scan the calibration QR code on the QR code pasting area 11 of the positioning plate 7 using a dedicated device to obtain calibration parameters. Input the calibration parameters into the control box 18. The control box 18 calibrates the detection accuracy of the proximity switch 23, the stroke of electric push rod 19 and electric push rod 24, the meshing clearance of rack 16 and toothed plate 15, and the fitting clearance of guide plate 30 and guide groove 29 according to the calibration parameters. This corrects the positioning deviation and ensures the accuracy of guide rail movement positioning and charging docking positioning, avoiding increased positioning error due to mechanical wear.

[0048] Intelligent charging system

[0049] The intelligent charging system of the present invention is adapted to the above-mentioned mobile charging pile and positioning method, and is used to realize intelligent charging, status monitoring and remote management of the charging pile, thereby improving the intelligence level and ease of operation and maintenance of the equipment.

[0061] Intelligent charging system workflow

[0062] The intelligent charging system of this invention operates as follows, combining the structure of a mobile charging station and a positioning method to achieve intelligent control throughout the entire process:

[0064] 2. Command Reception: When a remote terminal or the device to be charged sends a charging request and a positioning command, the control module control box 18 receives the command through the wireless communication module, parses the location of the designated area of ​​the main guide rail 1 or the secondary guide rail 2, and the charging parameter requirements.

[0065] 3. Precise Positioning: The control module activates the positioning control software, controlling the electric push rod 19 to rotate the rotating ring 14 and the adjusting guide rail 12, aligning the adjusting guide rail 12 with the target guide rail main rail 1 or secondary guide rail 2.

[0068] 6. Fault Handling: If the fault detection unit detects a fault such as a motor fault, docking fault, or circuit fault, it immediately sends a fault signal to the control module. The control module triggers the alarm speaker of the interaction module, and indicator light 10 changes to the fault color. At the same time, the fault information, fault type, and fault location are sent to the remote terminal via the wireless communication module. Staff can scan the equipment information QR code in the QR code pasting area 11 to view the equipment parameters, or view the fault details through the remote terminal and perform timely repairs. After the repairs are completed, the system returns to normal standby mode.

[0069] Example 1: A mobile charging pile, its positioning method and intelligent charging system

[0070] In this embodiment, the main guide rail 1 and the secondary guide rail 2 of the mobile charging pile are made of stainless steel, each 5m long, with an I-shaped cross-section to ensure the load-bearing capacity and wear resistance of the guide rails; the electric hoist moving structure 5 uses a CD1-10D electric hoist with a rated load capacity of 1000kg to ensure stable movement of the mobile charging cabinet 6; the control box 18 has a built-in STM32 microcontroller, and the wireless communication module uses a WiFi module, supporting 2.4G WiFi communication, which can realize real-time interaction with the mobile APP; the electric push rod 19 and the electric push rod 24 use DTZ100 electric push rods with a stroke of 500mm and an adjustment accuracy of ±1mm; the proximity switch 23 uses an E2E-X10ME1 inductive proximity switch with a detection distance of 10mm to ensure accurate positioning detection.

[0071] In the positioning method of this embodiment, the error of the guide rail movement positioning is controlled within ±3mm. The charging docking positioning is assisted by the inclined plate 31 on the guide plate 30 with an inclination angle of 30° to ensure smooth docking between the charging head 27 and the interface of the device to be charged. The positioning calibration cycle is 1 month. The calibration parameters are obtained by scanning the calibration QR code and input into the control box 18 to complete the calibration.

[0072] In the intelligent charging system of this embodiment, the intelligent charging software supports adaptive adjustment of 0-30V voltage and 0-10A current, which can be adapted to different types of electric vehicles and mobile mechanical equipment; the status monitoring software collects equipment status data every 10 seconds and generates daily, weekly and monthly operation reports; the remote management software supports multi-terminal login, can manage multiple charging piles at the same time, and the fault alarm response time does not exceed 10 seconds.

[0073] The working process of this embodiment is as follows: The main guide rail 1, the secondary guide rail 2, and the conversion seat 3 are hoisted and fixed to the workshop ceiling via the hoisting connector 4. The positioning plate 7 is installed at the end of the secondary guide rail 2. The mobile charging cabinet 6 is connected to the electric hoist moving structure 5, completing the equipment installation. When the equipment is in standby mode, the conductive connector 8 is inserted into the conductive connector hole 9 to store energy for the mobile charging cabinet 6. When it is necessary to charge the electric forklift in the workshop, the staff sends a charging request and positioning command through a mobile APP. After receiving the command, the control box 18 controls the electric push rod 19 to move, causing the adjusting guide rail 12 to rotate and align with the main guide rail 1. The electric hoist moving structure 5 moves along the main guide rail 1 to the vicinity of the electric forklift. The electric push rod 24 adjusts the height of the charging head 27, and charging is started after docking is completed. During the charging process, the staff can check the charging progress through the mobile APP. After charging is completed, the equipment automatically resets to the standby position, completing one charging cycle.
