Description

Technical Field

[0001] This invention relates to the field of automatic battery pack unpacking technology, and more specifically to an automatic battery pack unpacking system. Background Technology

[0002] The market share of wheeled vehicles and light four-wheeled vehicles continues to grow. Battery swapping, with its advantages of high energy replenishment efficiency and centralized battery management for enhanced security, is gradually replacing traditional home slow charging and becoming an important method for energy replenishment of light electric vehicles. Currently, battery swapping operators have widely deployed floor-standing battery swapping cabinets in urban residential areas, food delivery stations, and courier outlets. These cabinets typically employ a modular cabinet structure with multiple battery compartments arranged along their height. Each compartment has a built-in charging interface, communication identification module, and electronic door lock. After scanning the QR code on the cabinet or entering their account information via a mobile application, the cabinet control system verifies the user's identity and checks for available fully charged batteries. It then sequentially opens the doors of empty compartments to allow the user to insert a depleted battery. Once a battery is detected to be charging, the door closes, and then another fully charged compartment door opens for the user to retrieve a fully charged battery, thus completing the battery swapping operation.

[0003] However, existing battery swapping cabinets have the following problems in actual operation: The overall height of the cabinets is usually between 1.6 meters and 2.0 meters. The upper compartment (more than 1.4 meters above the ground) requires a high operating height when retrieving and placing batteries, while the weight of a single lightweight automotive lithium battery generally ranges from 8 kg to 15 kg, and some large-capacity batteries can weigh more than 20 kg. When users who are small or lack strength perform battery swapping operations, they need to lift the heavy batteries to a high position or remove them from a high position, which is physically demanding. During the process of retrieving and placing batteries at a high position, the center of gravity is very unstable, the hands slip, or the battery bumps against the cabinet, causing the battery to fall. Once the battery falls, it will not only cause damage to the outer shell and deformation of the internal cell structure, but may also cause safety hazards such as insulation failure and internal short circuits. During subsequent charging and discharging, there is a risk of thermal runaway, which seriously threatens the personal safety of users and the safe operation of the battery swapping cabinet.

[0044] Example

[0045] To address the technical problems in the background section, the following automatic battery pack ejection system is provided:

[0046] Combination Figures 1-14As shown, the present invention provides an automatic battery pack unloading system, including a battery cabinet 100. A square array of battery cavities 101 is arranged on one side of the battery cabinet 100. A guide blocking assembly 200 is installed in each battery cavity 101, and a battery assembly 300 is installed in each battery cavity 101. A protective shell 400 is fixedly connected to the front of the battery cabinet 100. A material handling device 500 is installed inside the protective shell 400. An inlet / outlet hole 401 is provided on one side of the protective shell 400. A display screen 600 is fixedly connected to one side of the protective shell 400 and above the inlet / outlet hole 401. A camera 700 is fixedly connected to the upper part of one side of the protective shell 400. The material handling device 500 includes a first horizontal track 501 and a second horizontal track 502. The first horizontal track 501 is fixedly connected to the bottom of the inner cavity of the protective shell 400, and the second horizontal track 502 is fixedly connected to the top surface of the inner cavity of the protective shell 400. A vertical track 50 is slidably connected between the first horizontal track 501 and the second horizontal track 502. 3. An L-shaped rod 504 is slidably connected to one side of the vertical track 503. A material pick-and-place assembly is installed at one end of the L-shaped rod 504. The material pick-and-place assembly includes a forward-moving component, a rotating component is installed on the top surface of the forward-moving component, a material pick-and-place assembly is installed on the top surface of the rotating component, and an unlocking component is symmetrically installed on the top surface of the material pick-and-place assembly. The material pick-and-place assembly includes a U-shaped frame 505, and a U-shaped frame 505 is installed at the output end of the rotating component. The bottom of the inner cavity of the U-shaped frame 505... The part is equipped with roller track 506. Pushing track 507 is fixedly connected to both sides of the inner wall of U-shaped frame 505. Pushing screw 508 is rotatably connected inside the pushing track 507. The surface of the pushing screw 508 is threaded with a locking structure. One end of the two sets of pushing tracks 507 is fixedly connected to a connecting plate 509. A first dual-axis motor 510 is fixedly connected to one side of the connecting plate 509. The output end of the first dual-axis motor 510 is rotatably connected to the pushing screw 508 through a worm gear and worm wheel.

[0047] Through the above structure:

[0048] 1. The array-type battery cavity enables centralized storage and zoned charging of multiple battery groups. The guide and blocking components work together to limit the charging of batteries in the cavity. One device can manage multiple batteries at the same time.

[0049] 2. The three-axis track (upper and lower double-layer horizontal track + vertical track) drives the material picking and placing component to move throughout the entire area inside the protective shell. It can be precisely moved to any empty / fully charged battery cavity or inlet / outlet hole station to complete cross-station transfer.

[0050] 3. The forward-moving component enables the battery to be fed forward and backward, and the rotating component enables the battery to be rotated 180°, automatically adjusting the battery power slot to face the inside of the battery cavity, eliminating the need for manual adjustment of the battery placement direction;

[0051] 4. The U-shaped frame and roller track provide support for battery placement. The dual-sided synchronous pushing screw and the first dual-axis motor worm gear drive the battery evenly, which can smoothly push the battery into the battery cavity or pull it out of the cavity. The locking structure, together with the roller track, locks the battery after placement to prevent it from slipping.

[0052] 5. The top unlocking component can be fed synchronously with the material handling component, automatically opening the blocking structure at the rear of the battery cavity, releasing the battery tail limit, and realizing battery unmanned unlocking and removal from the box.

[0053] In this embodiment, the locking structure includes a movable plate 512, the surface of the pusher screw 508 is threadedly connected to the movable plate 512, the lower part of the movable plate 512 is rotatably connected to the shaft 513, one end of the shaft 513 is fixedly connected to the baffle 514, one side of the movable plate 512 is fixedly connected to the second dual-axis motor 524, and the output end of the second dual-axis motor 524 is rotatably connected to the shaft 513 through a worm gear and worm wheel.

[0054] By engaging the moving plate with the threaded screw, it moves back and forth synchronously with the screw, allowing for synchronous feeding / retraction with the battery, and maintaining synchronization between the limit structure and the battery throughout the entire process.

[0055] The second dual-axis motor drives the shaft via a worm gear to rotate the baffle: after the battery is placed, the baffle flips up and abuts against the front of the battery housing, forming a hard limit at the front end to prevent the battery from sliding forward from the U-shaped frame roller track; after the battery is inserted into the cavity, the baffle flips in the opposite direction to release the limit, and the material handling assembly can be smoothly retracted.

[0056] In this embodiment, the locking structure also includes a long guide rod 511, and the long guide rod 511 is symmetrically fixedly connected to the other side of the moving plate 512.

[0057] The long guide rod serves two purposes: firstly, it ensures that the battery is not placed upside down when the staff places it; secondly, it limits the battery to prevent it from moving up and down; and finally, it guides the battery.

[0058] In this embodiment, the forward moving component includes a forward moving track 515, one end of an L-shaped rod 504 is fixedly connected to the forward moving track 515, a forward moving screw 516 is rotatably connected inside the forward moving track 515, one end of the forward moving track 515 is fixedly connected to a forward moving motor 517, and the output end of the forward moving motor 517 is fixedly connected to the forward moving screw 516.

[0059] The forward moving motor drives the forward moving screw to rotate independently, which in turn drives the entire set of rotating parts, picking and placing parts, and unlocking parts to feed forward and backward in small increments. This serves two purposes: firstly, it unlocks the parts to facilitate picking and placing the batteries; secondly, it facilitates the docking of the picking and placing components with the tail of the battery. Finally, the forward and backward displacement creates space to facilitate rotation and reversal.

[0060] In this embodiment, the rotating component includes a forward moving plate 518, the surface of the forward moving screw 516 is threadedly connected to the forward moving plate 518, the bottom surface of the forward moving plate 518 is fixedly connected to a rotary motor 519, the output end of the rotary motor 519 is rotatably connected to a rotating shaft 520 through a worm gear and worm wheel, and the top surface of the rotating shaft 520 is fixedly connected to a rotating plate 521.

[0061] The rotating plate can be rotated 180° by a rotating motor through a worm gear, which drives the U-shaped frame and the battery to change direction, turning the battery power slot into the battery cavity, so that the battery can be directly plugged in for charging after being pushed in.

[0062] The battery orientation can be switched between two working modes: when storing the battery, it is flipped to connect to the charging interface; when retrieving the battery, it is flipped so that the handle slot faces outward, making it convenient for staff to retrieve the battery.

[0063] In this embodiment, the unlocking component includes a bent rod 522. The top surface of the U-shaped frame 505 is symmetrically and fixedly connected to the bent rod 522, and one end of the bent rod 522 is fixedly connected to a triangular block 523.

[0064] When the forward-moving component feeds, the inclined triangular block contacts the battery cavity unlocking post first. Relying on the inclined thrust, the unlocking post is lifted upward, which in turn moves the unlocking plate and L-shaped plate upward, compressing the second damping rod and automatically releasing the battery tail blocking limit. No manual operation is required throughout the process. When the material handling assembly retracts, the triangular block retracts synchronously, and the damping rod's elasticity drives the L-shaped plate and unlocking post to automatically fall back to reset, blocking the battery tail again to prevent the battery from sliding out of the cavity during charging.

[0065] In this embodiment, the guide blocking assembly 200 includes a first roller guide rail 201, a second roller guide rail 202, a pressing blocking component, and a power plug 203. The first roller guide rail 201 is installed at the bottom of the inner cavity of the battery cavity 101, the second roller guide rail 202 is installed on both sides of the inner cavity of the battery cavity 101, the pressing blocking component is installed on the top surface of the inner cavity of the battery cavity 101, and the power plug 203 is fixedly connected to one end of the inner cavity of the battery cavity 101.

[0066] The combination of bottom and double-sided roller guide rails forms a three-sided guide channel. When the battery is pushed in / pulled out, the rollers roll to reduce frictional resistance, guide and limit the movement to prevent the battery from shifting up, down, left, or right. Pushing and pulling are smooth and do not jam.

[0067] With the built-in power plug in the cavity, the battery automatically connects to the battery power slot after it is fully inserted into the cavity, realizing automatic recharging of the depleted battery without the need for manual plugging and unplugging of the charging connector.

[0068] In this embodiment, the downward blocking component includes a first damping rod 204. The first damping rod 204 is symmetrically fixedly connected to the top of the inner cavity of the battery cavity 101, and an arc-shaped plate 205 is fixedly connected to the bottom surface of the first damping rod 204.

[0069] By using the first damping rod in conjunction with the arc-shaped plate, when the battery is pushed into the battery cavity, the battery is initially limited to prevent displacement of the battery within the battery cavity when the material handling components detach from the battery.

[0070] In this embodiment, the pressing blocking component also includes a second damping rod 206. The second damping rod 206 is fixedly connected to the top surface of the inner cavity of the battery cavity 101 and in front of the first damping rod 204. An L-shaped piece 207 is fixedly connected to the output end of the second damping rod 206. An unlocking piece 208 is fixedly connected to one side of the L-shaped piece 207. An unlocking post 209 is fixedly connected to the upper part of one side of the unlocking piece 208.

[0071] Under normal conditions, the second damping rod pushes the L-shaped plate down, and the L-shaped plate blocks the tail of the battery casing, preventing the battery from sliding out of the battery cavity during the charging process;

[0072] When the triangular block feeds and pushes the unlocking column, the unlocking plate drives the L-shaped plate to compress the second damping rod upward, and the tail block is fully lifted, unlocking the tail limit of the battery, allowing the battery to be pushed in and pulled out smoothly.

[0073] In this embodiment, the battery assembly 300 includes a battery housing 301. Guide grooves 302 are symmetrically arranged on the lower parts of both sides of the battery housing 301. A power slot 303 is provided at one end of the battery housing 301. A handle slot 304 is provided at one end of the battery housing 301. A handle 305 is rotatably connected in the handle slot 304.

[0074] The guide grooves on both sides work precisely with the long guide rod of the locking structure to achieve left and right positioning when placing and dragging the battery, ensuring stable clamping; the power slot at the end matches the power plug in the battery cavity, and the battery is automatically plugged in and charged when it enters the cavity; handle slot + rotatable handle: after a fully charged battery is delivered to the inlet and outlet, the staff can pull out the handle to hold and take away the battery. When storing, the handle can be rotated back into the slot, without occupying the battery cavity space and without interfering with the automatic pushing and pulling action.

[0075] Working principle and usage process of this invention:

[0076] In use:

[0077] Battery replacement involves two scenarios: inserting a depleted battery and removing a fully charged battery. The specific operating procedures are as follows:

[0078] Operating Condition 1: Store the recharged batteries in battery cabinet 100:

[0079] Step 1: The staff uses their mobile phone to scan the QR code on the display screen 600. After scanning, the internal material handling device 500 is activated. The device drives the material handling component to move to the inlet / outlet position 401 through the first horizontal track 501, the second horizontal track 502 and the vertical track 503.

[0080] Step 2: The worker places the battery on the pick-and-place assembly. The placement procedure is as follows: First, place one end of the battery casing 301 above the roller track 506. Then, align the guide grooves 302 on both sides of the battery casing 301 with the long guide rod 511. Push the battery casing 301 forward so that it slides along the roller track 506 into the middle of the two sets of roller tracks 506. The bottom of the battery casing 301 should be against one side of the moving plate 512, indicating that the battery is in place. After the battery is positioned, start the second dual-axis motor 524. The motor rotation drives the two sets of shafts 513 to rotate at a certain angle. The shafts 513 synchronously drive the baffle 514 to flip. After the baffle 514 rotates, it abuts against the front of the battery casing 301 to prevent the battery casing 301 from slipping off the pick-and-place assembly.

[0081] Step 3: After the battery is fixed, the first horizontal track 501, the second horizontal track 502, and the vertical track 503 move the material handling assembly and the entire battery inside the protective shell 400, transporting the battery to the empty battery cavity 101. Upon arrival at the target battery cavity 101, the rotary motor 519 is activated. The rotary motor 519 drives the rotary shaft 520 to rotate, which in turn rotates the rotary plate 521 by 180°. Simultaneously, the rotary plate 521 rotates the material handling assembly, the unlocking assembly, and the battery shell 301 by 180°, so that the power slot 303 of the battery shell 301 faces the inside of the battery cavity 101.

[0082] Step 4: Push the battery into the battery chamber 101. Specific actions: ① Start the forward moving motor 517. The forward moving motor 517 drives the forward moving screw 516 to rotate, which drives the rotating part, the material picking and placing part, the unlocking part and the battery to move forward as a whole. During the forward movement of the unlocking part, its upper triangular block 523 first contacts the unlocking post 209 and pushes the unlocking post 209 upward. The unlocking post 209 simultaneously drives the unlocking piece 208 and the L-shaped piece 207 to move upward. During the lifting process of the L-shaped piece 207, it squeezes the second damping rod 206. After the L-shaped piece 207 moves to the highest stroke position, the forward moving motor 517 is turned off. ② Start the first dual-axis motor 510, which drives two sets of forward-moving screws 516 to rotate, pushing the moving plate 512 forward. The moving plate 512 simultaneously drives the shaft 513, baffle 514, and long guide rod 511 to move forward together, pushing the battery into the battery cavity 101. The battery feeding process is guided and limited by a set of first roller guide rails 201 and two sets of second roller guide rails 202 until the battery is completely inside the battery cavity 101. After the battery is completely inside the cavity, the power slot 303 of the battery housing 301 is inserted into the power plug 203. At the same time, the arc plate 205 presses the top surface of the battery housing 301 under the elastic force of the first damping rod 204, restricting the movement of the battery housing 301 in the battery cavity 101. After the power slot 303 and the power plug 203 are fully connected, the battery can be charged.

[0083] Step 5: Reset and exit the battery cavity 101 of the material handling assembly: ① Start the second dual-axis motor 524 to drive the baffle 514 to flip and release the front end limit of the battery housing 301; then start the first dual-axis motor 510 to drive the moving plate 512, shaft 513, and baffle 514 back to the initial position. ② Start the forward moving motor 517, and the forward moving screw 516 rotates, driving the entire material handling assembly to retreat and reset; when the assembly retreats, the triangular block 523 retracts synchronously, and the unlocking post 209, L-shaped piece 207, and unlocking piece 208 fall back and reset synchronously; after reset, the L-shaped piece 207 abuts against the tail of the battery to prevent the battery housing 301 from coming out of the battery cavity 101. At this point, the battery storage and charging process is completed.

[0084] Operating Circumstance 2: Remove the fully charged battery from the battery cabinet:

[0085] Step 1: Drive the material handling assembly to move to the outside of the battery cavity 101 where the fully charged battery is stored by the first horizontal track 501, the second horizontal track 502, and the vertical track 503.

[0086] Step 2: The forward screw 516 drives the rotating component, the material handling component, and the unlocking component to move forward as a whole; after the unlocking component moves forward, the triangular block 523 lifts the unlocking mechanism, releasing the L-shaped piece 207 from blocking the tail of the battery casing 301.

[0087] Step 3: The pusher screw 508 drives the moving plate 512, shaft 513, baffle 514, and long guide rod 511 to push forward together; the long guide rod 511 moves forward and inserts into the guide grooves 302 on both sides of the battery housing 301; the baffle 514 automatically flips after reaching the end of the battery and locks the front end of the battery housing 301; then the pusher screw 508 rotates in the opposite direction, driving the baffle 514 and shaft 513 to pull backward, extracting the fully charged battery from the battery cavity 101. After the battery is extracted, the rotary motor 519 is started, and the motor drives the picking and placing component and the fully charged battery to rotate 180° as a whole; the track mechanism transports the picking and placing component to the inlet / outlet hole 401, and the operator can then remove the fully charged battery from the picking and placing device 500, completing the entire battery swapping operation.
