Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly relates to a charging pile with manual and automatic integration and its usage method. Background Art

[0002] Currently, the charging pile market is mainly divided into two categories: public and civilian. Limited by technology and power supply conditions, civilian charging piles generally do not have the fast charging function. Moreover, civilian electricity is charged according to different time periods. When users use civilian charging piles, they often need to manually operate the charging during low-price electricity periods (such as at night). Not only does it take time and energy to go downstairs to connect the charging equipment, but it is also easy to miss the low electricity price period due to forgetting the time, resulting in an increase in electricity costs. In addition, the charging guns of traditional charging piles are placed completely exposed, making the charging guns vulnerable to external factors. Also, the cables of the charging guns are relatively long and are placed completely exposed. This not only occupies a large amount of space and affects the aesthetics, but also easily causes large-area wear of the cables, reducing the service life of the cables and posing potential safety hazards during use. Therefore, we propose a charging pile with manual and automatic integration and its usage method. Summary of the Invention

[0003] The main purpose of the present invention is to provide a charging pile with manual and automatic integration and its usage method, which can effectively solve the problems in the background art.

The rear end of the rewinding roller is movably connected to the rear inner wall surface of the square frame through a rotating shaft.

[0015] A usage method of a manual-automatic integrated charging charging pile includes a manual control usage method: Step 1: Park the electric vehicle to be charged at a suitable position near the charging pile body. Press the control button of the stretching mechanism in the receiving component. The first servo motor starts to operate. The first servo motor drives the first circular gear fixedly connected to its output end to rotate. Since the first circular gear is meshed with the second circular gear, the second circular gear rotates accordingly. The movable rod fixedly connected to the front end of the second circular gear drives the first lower sector gear to rotate under the cooperation of the bearing. Also, because the first upper sector gear and the first lower sector gear are relatively meshed, the first upper sector gear also starts to rotate. Both drive the first stretching arm to act. At the same time, the second upper sector gear and the second lower sector gear drive the second stretching arm to act under transmission. The first stretching arm and the second stretching arm drive the connecting plate to move outward along the guiding groove through the third stretching arm, the fourth stretching arm, and the corresponding first middle sector gear and second middle sector gear, so that the movable sleeve plate and the gun seat are pushed out of the receiving box. At this time, the charging gun can be taken off the gun seat; Step 2: Insert the taken charging gun into the charging interface of the electric vehicle. Set charging parameters such as charging duration and charging power on the control panel of the control box. After setting is completed, press the start button. The on-off switch in the control box closes, and the charging pile body starts to charge the electric vehicle; Step 3: When charging is completed, manually press the stop button. The on-off switch in the control box disconnects, and charging stops. Insert the charging gun back into the gun seat. Press the control button of the stretching mechanism again. The first servo motor rotates in the reverse direction, driving each component to move in the reverse direction, and retracting the charging gun into the receiving box to complete the manual charging operation; Step 4: Start the second servo motor, which drives the main transmission gear to rotate, and the rack transmission belt meshing with the main transmission gear moves, driving the auxiliary transmission gear and the winding roller to rotate, and winding the charging cable on the winding roller; Also includes automatic control usage: Step 1: Follow steps 1 to 2 of the manual control method to control the extension mechanism to extend the charging gun, remove the charging gun from the gun holder, and insert the charging gun into the charging port of the electric vehicle; Step 2: Open the mobile phone APP, enter the specific charging parameters of charging time, charging duration, charging power and the command to query the charging status on the interface, and the control signal is transmitted to the control cabinet through the network. The Siemens SIMATIC S7-1200 series programmable logic controller in the control cabinet receives and processes the signal, stores the set command and waits for execution; Step 3. When the set charging time is reached, the control cabinet sends a start signal to the control box, the timer in the control box triggers the on and off, and the charging pile body starts to charge the electric vehicle. During the charging process, the control box collects charging data in real time, such as charging current, voltage, and power, and feeds the data back to the control cabinet, which is then transmitted to the mobile phone APP. Users can check the charging status and charging progress at any time through the mobile phone APP. At the same time, the leakage protection and pulser in the control box continue to work to ensure charging safety and stability. If there is an abnormal leakage, the leakage protection device will cut off the circuit in time. Step 4. When the set charging time is over, the timer in the control box triggers the on-off switch to disconnect and stop charging. When the car is needed, unplug the charging gun from the charging port of the electric car and insert it back into the gun holder, control the first servo motor to rotate in the opposite direction, drive all components to move in the opposite direction, and retract the charging gun into the storage box. At the same time, according to step 4 of the manual control method, rewind the charging cable on the reel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has two control modes, manual and automatic. Manual control can ensure normal charging when automatic control fails or there is a special need. Automatic control can realize remote intelligent operation to meet the use requirements of different scenarios, improve user experience and charging pile applicability. The control cabinet is built with Siemens SIMATIC S7-1200 series programmable logic controller. The charging time parameters are set through the mobile phone APP. The timer and the on-off switch in the control box work together. When the set time is reached, the charging pile and the power grid circuit are automatically connected to realize automatic charging during the night off period. No manual operation is required by the user, which effectively reduces the charging cost and avoids the inconvenience caused by forgetfulness. 2. In the present invention, the extension mechanism in the storage component is driven by a first servo motor. Using the principle of gear transmission, it drives the movable sleeve plate and the gun seat to push out or retract into the storage box. During charging, it controls the charging gun to extend, and after charging is completed, it controls the charging gun to retract, which plays a protective role for the charging gun and extends its service life. 3. In the present invention, the second servo motor of the winding mechanism drives the main transmission gear, the rack transmission belt, the secondary transmission gear and the winding roller to operate in coordination. After charging is completed, the excess charging cable that leaks out is wound up, avoiding wear of the excess charging cable that leaks out, improving the service life of the charging cable, and at the same time enhancing the safety and cleanliness of the charging pile during use.

Press the control button of the stretching mechanism 63 in the receiving component 5. The first servo motor 637 starts to operate. The first servo motor 637 drives the first circular gear 638 fixedly connected to its output end to rotate. Since the first circular gear 638 is meshed with the second circular gear 639, the second circular gear 639 rotates accordingly. The movable rod 6391 fixedly connected to the front end of the second circular gear 639 drives the first lower sector gear 633 to rotate with the cooperation of the bearing. Also, because the first upper sector gear 632 and the first lower sector gear 633 are meshed with each other relatively, the first upper sector gear 632 also starts to rotate. The two respectively drive the first stretching arm 6392 to move. At the same time, the second upper sector gear 634 and the second lower sector gear 635 drive the second stretching arm 6393 to move under transmission. The first stretching arm 6392 and the second stretching arm 6393 drive the connecting plate 636 to move outwards along the guiding groove 52 through the third stretching arm 6394, the fourth stretching arm 6395 and the corresponding first middle sector gear 6396 and second middle sector gear 6397, so that the movable sleeve plate 64 and the gun seat 65 are pushed out of the receiving box 51.

The second servo motor 83 drives the main transmission gear 84 to rotate, and the rack transmission belt 85 engaged with the main transmission gear 84 moves, driving the secondary transmission gear 86 and the winding roller 87 to rotate, and winds the charging cable 88 on the winding roller 87; It also includes an automatic control usage method: Step 1: According to Steps 1 to 2 of the manual control usage method, control the extension mechanism 63 to extend the charging gun 82, remove the charging gun 82 from the gun holder 65, and insert the charging gun 82 into the charging interface of the electric vehicle; Step 2: Open the mobile APP, enter the specific charging parameters of the set charging time, charging duration, and charging power and the instruction to query the charging status on the interface. The control signal is transmitted to the control cabinet 3 through the network. The Siemens SIMATIC S7-1200 series programmable logic controller in the control cabinet 3 receives and processes the signal, stores the set instruction and waits for execution; Step 3: When the set charging time arrives, the control cabinet 3 sends a start signal to the control box 4. The timer in the control box 4 triggers the on-off switch to close, and the charging pile body 2 starts to charge the electric vehicle. During the charging process, the control box 4 collects the charging data in real time, such as charging current, voltage, and power, and feeds the data back to the control cabinet 3, and then the control cabinet 3 transmits it to the mobile APP. The user can query the charging status at any time through the mobile APP to understand the charging progress. At the same time, the leakage protection and pulsator in the control box 4 keep working to ensure charging safety and stability. If there is an abnormal situation of leakage, the leakage protection device will cut off the circuit in time; Step 4: When the set charging time ends, the timer in the control box 4 triggers the on-off switch to disconnect, and the charging stops. When the vehicle is needed, pull out the charging gun 82 from the charging interface of the electric vehicle and insert it back into the gun holder 65. Control the first servo motor 637 to rotate in the reverse direction, drive each component to move in the reverse direction, and retract the charging gun 82 into the storage box 51.
