Description
Technical Field
[0001] This invention relates to the field of battery swapping station technology, and in particular to a method for locating and capturing batteries at a new energy vehicle battery swapping station. Background Technology
[0002] Automatic battery swapping for new energy vehicles is one of the most efficient ways to replenish their power, and its efficiency is far faster than the current mainstream charging pile charging method.
[0003] One crucial aspect of building new energy vehicle battery swapping stations is the battery positioning and retrieval method. Achieving rapid battery swapping is paramount, especially for light trucks where the large size and weight of batteries make automated retrieval and placement difficult. The success or failure of battery positioning and retrieval directly impacts the success or failure of the battery swapping station.
[0004] Another aspect is the battery storage device. Large commercial vehicles, in particular, have batteries that are large and heavy, making automated loading and unloading difficult. Traditional battery swapping stations, which primarily use stacker crane forks, cannot meet the storage and retrieval needs of these batteries. Therefore, the design of the battery storage device becomes especially important. Summary of the Invention
[0005] The present invention aims to provide a method for locating and capturing batteries at battery swapping stations for new energy vehicles to overcome or at least partially solve the above-mentioned problems.
[0006] To achieve the above objectives, the technical solution of the present invention is specifically implemented as follows:
[0007] This invention provides a method for locating and capturing battery swapping stations for new energy vehicles, comprising the following steps:
[0008] Step 1: Driven by the motor-driven walking assembly, the stacker crane moves to the side of the vehicle ready for battery swapping.
[0009] Step two: The unlocking mechanism runs on the stacker crane. After running to the appropriate position, the camera on the unlocking mechanism takes a picture and transmits the unlocking position of the battery on the frame to the software. After the software algorithm calculates, the current unlocking position is determined.
[0010] Step 3: The stacker crane lifting component drives the chain to move the platform up and down vertically. After reaching the appropriate position, it stops. Then, the rotating platform rotates at a certain angle under the drive of the motor and stops. The unlocking mechanism moves forward again, and then the electric cylinder drives the positioning component. The positioning pin is inserted into the battery rack, and then the unlocking motor is also inserted into the unlocking position. The unlocking motor rotates to unlock the battery. Then the traction group pulls the battery out and completely onto the stacker crane. After that, the stacker crane starts to run under the drive of the front and rear drive motors.
[0011] Step four: The stacker crane transports the batteries to an empty battery rack. Then, the stacker crane starts to drive the lifting component to lift the batteries that need to be charged up and down. Then, the rotating platform rotates. Finally, driven by the unlocking mechanism, the batteries that need to be charged are pushed to an empty position in the battery rack. Then, the battery charging interface is charged under the drive of the electric cylinder.
[0012] Step 5: The unlocking mechanism is driven to the battery position, the electric cylinder drives the positioning component, and the positioning pin is inserted into the battery holder;
[0013] Step six: The unlocking mechanism pulls the fully charged battery into the stacker crane and stops dragging it when it reaches the designated position. Then, the stacker crane's drive motor moves the battery.
[0014] Step 7: The camera on the stacker crane takes a picture and transmits the battery unlock position on the frame to the software. After the software algorithm calculates, the current unlock position is determined.
[0015] Step 8: The rotating platform rotates to a certain angle and stops under the drive of the motor. The unlocking mechanism then moves forward to push the battery into the new energy vehicle battery position. After it is in place, the electric cylinder drives the positioning component, and the positioning pin is pulled out from the battery rack. Then the unlocking motor is also inserted into the unlocking position. The unlocking motor rotates to lock the battery. Then the unlocking mechanism retracts and moves to the appropriate position of the stacker. The stacker moves to the designated position under the action of the drive motor.
[0016] Step nine: The hydraulic lifting platform lowers the new energy vehicle, and the new energy vehicle that has completed the battery swapping leaves the battery swapping station.
[0017] As a further aspect of the present invention, step one further includes the following steps:
[0018] The front and rear centering mechanisms of the battery swapping station operate to position and center the front and rear wheels of the new energy vehicles that need to be swapped.
[0019] The hydraulic lifting platform lifts the entire new energy vehicle. This lifting process is to prevent the new energy vehicle from becoming uneven due to load or other reasons, which could lead to inaccurate battery swapping positioning and thus battery swapping failure.
[0020] As a further embodiment of the present invention, in step two, the software algorithm includes a visual positioning algorithm and an electrical program algorithm.
[0021] As a further aspect of the present invention, the battery positioning and grabbing methods include positioning and grabbing of batteries on the vehicle, positioning and installing fully charged batteries, positioning and storing batteries on the battery rack, and positioning and grabbing of batteries on the battery rack.
[0022] As a further aspect of the present invention, the positioning and grasping of the vehicle battery includes the following steps;
[0023] The stacker crane uses the power source of the stacker crane walking component to drive the connecting shaft to rotate, which in turn drives the drive wheel to rotate. This allows the stacker crane overhead rail component to move along the X direction on the ground rail component and reach the rear of the vehicle that needs battery swapping.
[0024] The lifting mechanism lifts the power source to drive the drive sprocket to rotate, which in turn drives the lifting chain to rotate.
[0025] The lifting chain will move the unlocking mechanism's walking components downwards to the rear of the vehicle;
[0026] The unlocking mechanism uses the power source of the walking mechanism to drive the gears to move the walking component of the unlocking mechanism toward the rear of the vehicle, and stops moving after reaching the shooting position;
[0027] After the unlocking mechanism reaches the rear of the vehicle, the camera takes a picture of the battery on the vehicle to confirm the location of the battery lock hole;
[0028] After confirming the position of the battery lock hole, the unlocking mechanism moves and the unlocking gun is inserted into the screw hole for battery unlocking. Driven by the unlocking gun power source, the unlocking gun rotates, which in turn rotates the screw hole for battery unlocking to unlock the lock.
[0029] Driven by the hook power source, the hook presses down and latches onto the battery moving flange. The unlocking mechanism pulls the battery, and through the power source of the walking mechanism, the gears move towards the end of the stacker crane via the unlocking mechanism walking assembly, pulling the entire battery into the lifting assembly of the unlocking mechanism walking assembly.
[0030] As a further embodiment of the present invention, the positioning and installation of the fully charged battery includes the following steps;
[0031] The stacker crane, carrying a fully charged battery, uses the power source of the stacker crane's walking component to drive the connecting shaft to rotate, which in turn drives the drive wheel to rotate. This allows the stacker crane's overhead rail component to move along the X direction on the ground rail component, reaching the rear of the vehicle that needs battery swapping.
[0032] The unlocking mechanism's walking component drives the drive sprocket to rotate via a power source, which in turn drives the lifting chain to rotate.
[0033] The lifting chain will move the unlocking mechanism's walking components downwards to the rear of the vehicle;
[0034] The unlocking mechanism uses the power source of the walking mechanism to drive the gears to move the unlocking mechanism walking component towards the rear of the vehicle. It stops at the rear of the vehicle via a servo motor, sensor and magnetic grid, ready to install the battery.
[0035] The unlocking mechanism moves, pushing the battery forward along the unlocking mechanism's moving assembly and inserting it into the light truck's battery mounting position.
[0036] Driven by the hook power source, the hook is lifted away from the battery moving flange opening;
[0037] Driven by its power source, the unlocking gun rotates, which in turn rotates the screw hole for battery unlocking, thus locking the lock.
[0038] The unlocking mechanism uses the power source of the walking mechanism to drive the gears to move the walking component of the unlocking mechanism towards the end of the stacker to complete the battery installation.
[0039] As a further embodiment of the present invention, the battery is positioned and stored on the battery rack, including the following steps;
[0040] The stacker crane uses the power source of the stacker crane walking component to drive the connecting shaft to rotate, which in turn drives the drive wheel to rotate. This allows the stacker crane overhead rail component to move along the X direction on the ground rail component and reach the rear of the charging compartment.
[0041] The lifting mechanism lifts the power source to drive the drive sprocket to rotate, which in turn drives the lifting chain to rotate.
[0042] The lifting chain will move the unlocking mechanism's walking component towards the battery's height, until it reaches behind the empty battery;
[0043] The unlocking mechanism uses the power source of the walking mechanism to drive the gears, which in turn push the battery toward the battery compartment shelf.
[0044] After the unlocking mechanism pushes the battery to the bottom of the shelf;
[0045] Driven by the hook power source, the hook moves upward and away from the battery moving flange, the unlocking mechanism retracts, and the battery is stored.
[0046] As a further embodiment of the present invention, the battery positioning and gripping on the battery rack includes the following steps;
[0047] The stacker crane uses the power source of the stacker crane walking component to drive the connecting shaft to rotate, which in turn drives the drive wheel to rotate. This allows the stacker crane overhead rail component to move along the X direction on the ground rail component and reach the rear of the charging compartment.
[0048] The lifting component of the unlocking mechanism drives the drive sprocket to rotate through the lifting power source, which in turn drives the lifting chain to rotate.
[0049] The lifting chain will move the unlocking mechanism's walking component towards the battery's height, until it reaches the rear of the battery;
[0050] The unlocking mechanism uses the power source of the walking mechanism to drive the gears to move the walking component of the unlocking mechanism behind the battery, and stops moving after reaching the shooting position;
[0051] After the unlocking mechanism reaches the back of the battery, the camera takes a picture of the battery on the battery holder to confirm the position of the battery lock hole;
[0052] After confirming the position of the battery lock hole, the unlocking mechanism moves and the unlocking gun is inserted into the screw hole for unlocking and unlocking the battery.
[0053] Driven by the hook power source, the hook presses down and latches onto the battery moving flange. The unlocking mechanism pulls the battery, and through the power source of the walking mechanism, the gears move towards the end of the stacker crane via the unlocking mechanism walking component, pulling the entire battery into the lifting component of the unlocking mechanism walking component, thus completing the battery grabbing.
[0054] This invention provides a method for locating and capturing batteries at battery swapping stations for new energy vehicles, with the following advantages:
[0055] The battery swapping positioning method differs from previous battery swapping positioning methods by adding a vision system and algorithms to the traditional mechanical mechanism. This makes the unlocking and positioning more accurate, has a higher success rate, and is more adaptable. It can adapt to various undesirable situations and provides a good solution for more accurate positioning of the battery swapping mechanism in battery swapping stations. It also provides a solution for battery swapping positioning mechanisms that cannot accurately locate. Compared with traditional pure mechanical positioning, it is more adaptable and has a higher success rate. Attached Figure Description

Detailed Implementation
[0063] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0064] See Figure 1-5 The present invention provides a method for locating and capturing battery swapping stations for new energy vehicles, comprising the following steps:
[0065] 1. Positioning method during the process of removing a battery that needs charging
[0066] First, the battery-swapping vehicle drives to the designated location within the battery-swapping station and stops. The station then identifies the vehicle's information and prepares for the battery swapping process.
[0067] First, the front and rear centering mechanisms of the battery swapping station begin operation, positioning and centering the front and rear wheels of the battery swapping vehicle.
[0068] The hydraulic lifting platform lifts the entire battery-swapping vehicle. This lifting process is to prevent the vehicle from becoming uneven due to load or other reasons, which could lead to inaccurate battery swapping positioning and thus battery swapping failure.
[0069] Driven by the motor-driven walking assembly, the stacker crane moves to the side of the vehicle ready for battery swapping.
[0070] The unlocking mechanism 3 runs on the stacker crane. After running to the appropriate position, the camera 305 on the unlocking mechanism 3 takes a picture and transmits the unlocking position of the battery on the frame to the software. After the software algorithm calculates, the current unlocking position is determined.
[0071] Then, the stacker crane lifting component 5 drives the chain to move the platform up and down vertically. After reaching the appropriate position, it stops. Then, the rotating platform rotates at a certain angle under the drive of the motor and stops. The unlocking mechanism 3 moves forward again, and then the electric cylinder drives the positioning component. The positioning pin is inserted into the battery rack, and then the unlocking motor is also inserted into the unlocking position. The unlocking motor rotates to unlock the battery. Then the traction group pulls the battery out and completely pulls it onto the stacker crane. After that, the stacker crane starts to run under the drive of the front and rear drive motors.
[0072] The stacker crane transports the batteries to an empty battery rack. Then, the stacker crane starts to drive the lifting assembly to lift the batteries that need to be charged up and down. Then, the rotating platform rotates, and finally, driven by the unlocking mechanism, the batteries that need to be charged are pushed to an empty position in the battery rack. Then, the battery charging interface is driven by the electric cylinder to start charging.
[0073] 2. Positioning method during the process of installing a fully charged battery on a battery-swapping vehicle.
[0074] First, the stacker crane drive motor moves back and forth to the appropriate position, and then the stacker crane drive lifting assembly lifts it up and down to the shelf position of the fully charged battery.
[0075] The unlocking mechanism 3 is driven to the battery position, and then the positioning component is dragged by the electric cylinder, and the positioning pin is inserted into the battery holder.
[0076] Then, the unlocking mechanism 3 pulls the fully charged battery into the stacker crane, stops dragging it when it reaches its position, and then the stacker crane drive motor moves.
[0077] It moves to the side of the vehicle ready for battery swapping and reaches the designated location.
[0078] Then the stacker crane lifting component drives the chain to move the platform up and down in the vertical direction until it reaches the appropriate position and stops.
[0079] The camera 305 on the stacker crane takes pictures and transmits the unlock position of the battery on the frame to the software. After the software algorithm calculates, the current unlock position is determined.
[0080] Subsequently, the rotating platform, driven by the motor, rotates to a certain angle and then stops. The unlocking mechanism 3 then moves forward to push the battery into the new energy vehicle battery position. Once in place, the positioning component is dragged by the electric cylinder, and the positioning pin is pulled out from the battery rack. Then, the unlocking motor is inserted into the unlocking position, and the unlocking motor rotates to lock the battery. Then, the unlocking mechanism 3 retracts and moves to the appropriate position on the stacker. The stacker moves to the designated position under the action of the drive motor.
[0081] The hydraulic lifting platform lowers the battery-swapping vehicle, and after other preparations are completed, the driver can drive the new energy vehicle away from the battery-swapping station.
[0082] I. Positioning and capturing of the battery on the vehicle: After the battery swapping vehicle enters the battery swapping station and comes to a stop, and is centered from left to right, the battery swapping vehicle is lifted to a certain height.

[0084] The lifting mechanism component 5 drives the active sprocket to rotate by lifting the power source, which in turn drives the lifting chain to rotate.
[0085] The lifting chain will move the unlocking mechanism walking component 7 downwards to the rear of the vehicle.
[0086] The unlocking mechanism 3 drives the gear in the unlocking mechanism walking component 7 to move towards the rear of the vehicle through the walking mechanism power source 301, and stops moving after reaching the shooting position.
[0087] After the unlocking mechanism 3 reaches the rear of the vehicle, the camera 305 takes a picture of the battery on the vehicle to confirm the location of the battery lock hole.
[0088] After confirming the position of the battery lock hole, the unlocking mechanism 3 moves, and the unlocking gun 306 is inserted into the bolt hole for battery unlocking. Driven by the unlocking gun power source 302, the unlocking gun 306 rotates, which in turn rotates the bolt hole for battery unlocking to unlock the lock.
[0089] Driven by the hook power source 303, the hook 304 presses down and latches onto the battery moving flange. The unlocking mechanism 3 pulls the battery through the walking mechanism power source 301, which drives the gear to move towards the end of the stacker in the unlocking mechanism walking assembly 7, pulling the entire battery into the unlocking mechanism walking assembly lifting assembly 5.
[0090] II. Positioning and Grabbing of Fully Charged Batteries: The battery swapping vehicle is lifted to a certain height, the depleted battery is removed, and a fully charged battery is installed.
[0091] The stacker crane, carrying a fully charged battery, drives the connecting shaft to rotate via the power source of the stacker crane walking component 2, which in turn drives the drive wheel to rotate. This allows the stacker crane overhead rail component 6 to move along the X direction on the ground rail component 1, reaching the rear of the vehicle requiring battery swapping.
[0092] The lifting mechanism component 5 drives the active sprocket to rotate by lifting the power source, which in turn drives the lifting chain to rotate.
[0093] The lifting chain will move the unlocking mechanism walking component 7 downwards to the rear of the vehicle.
[0094] The unlocking mechanism 3 drives the gear in the unlocking mechanism walking component 7 to move towards the rear of the vehicle through the walking mechanism power source 301. It stops at the rear of the vehicle through the servo motor, sensor and magnetic grid, ready to install the battery.
[0095] The unlocking mechanism 3 moves, pushing the battery forward along the unlocking mechanism travel component 7 and inserting it into the light truck battery mounting position.
[0096] Driven by the hook power source 303, hook 304 is lifted away from the battery moving flange opening.
[0097] Driven by the unlocking gun power source 302, the unlocking gun 306 rotates, which in turn rotates the bolt hole for battery unlocking to lock the lock.
[0098] The unlocking mechanism 3 uses the power source 301 of the walking mechanism to drive the gears in the walking component 7 of the unlocking mechanism to move towards the end of the stacker to complete the battery installation.
[0099] III. Positioning and storage of batteries on the battery rack: When the stacker crane stores the rechargeable batteries.
[0100] The stacker crane drives the connecting shaft to rotate through the power source of the stacker crane walking component 2, and drives the drive wheel to rotate in coordination with the stacker crane overhead rail component 6 to move along the X direction on the ground rail component 1 to reach the rear of the charging compartment.
[0101] The lifting mechanism component 5 drives the active sprocket to rotate by lifting the power source, which in turn drives the lifting chain to rotate.
[0102] The lifting chain will move the unlocking mechanism walking component 7 towards the height of the battery, until it reaches the rear of the empty battery.
[0103] The unlocking mechanism 3 drives the gears through the walking mechanism power source 301 to push the battery toward the battery compartment shelf in the unlocking mechanism walking component 7.
[0104] After the unlocking mechanism 3 pushes the battery to the bottom of the shelf.
[0105] Driven by the hook power source 303, the hook 304 moves upward and away from the battery moving flange, and the unlocking mechanism 3 moves backward, completing the storage of the battery.
[0106] IV. Battery positioning and grabbing on the battery rack: When the battery in the battery swapping compartment is confirmed to be fully charged and ready for use.
[0107] The stacker crane drives the connecting shaft to rotate through the power source of the stacker crane walking component 2, and drives the drive wheel to rotate in coordination with the stacker crane overhead rail component 6 to move along the X direction on the ground rail component 1 to reach the rear of the charging compartment.
[0108] The lifting mechanism component 5 drives the active sprocket to rotate by lifting the power source, which in turn drives the lifting chain to rotate.
[0109] The lifting chain will move the unlocking mechanism walking component 7 towards the height of the battery, until it reaches the rear of the battery.
[0110] The unlocking mechanism 3 drives the gear in the unlocking mechanism walking component 7 to move behind the battery through the walking mechanism power source 301, and stops moving after reaching the shooting position.
[0111] After the unlocking mechanism 3 reaches the rear of the battery, the camera 305 takes a picture of the upper battery inside the battery compartment to confirm the position of the battery lock hole.
[0112] After confirming the position of the battery lock hole, the unlocking mechanism 3 moves and the unlocking gun 306 is inserted into the screw hole for unlocking and unlocking the battery.
[0113] Driven by the hook power source 303, the hook 304 presses down and latches onto the battery moving flange. The unlocking mechanism 3 pulls the battery and drives the gear through the walking mechanism power source 301 to move the unlocking mechanism walking component 7 towards the end of the stacker, pulling the entire battery into the unlocking mechanism walking component lifting component 5, thus completing the battery grabbing.
