Description

Technical Field

[0001] This invention relates to the field of battery production equipment technology, specifically a mobile battery energy storage container. Background Technology

[0002] ZL202420215721.3 discloses an automatic battery pack loading device. The device uses a loading mechanism to move along a conveyor to transport the battery packs into a container. A carrying component supports the battery pack, and a lifting component moves the carrying component up and down to better align with the loading side of the container. A pushing component then pushes the battery pack into the container.

[0003] The above setup requires placing the battery pack on the carrier component, aligning it with the loading side, and then pushing it in. Although it can send the battery pack into the container, the process is relatively complicated and the loading efficiency is low. Using the loading and conveying mechanism will also occupy additional space and increase costs. Therefore, the present invention provides a mobile battery energy storage container. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile battery energy storage container to solve the problem of low packing efficiency mentioned in the background art.

The battery pack is placed on the transport device, which is fitted around the outside of the base frame to rotate cyclically on the outer wall of the base frame. The limiting device is located on the inner top of the fixed shell and the movable shell and is used to fit between adjacent battery packs to restrict the swaying of the battery packs.

[0007] The limiting device includes a third motor, a drive rod, and a limiting frame; the drive end of the third motor is threadedly connected to one end of the drive rod so that the drive rod can be moved by the rotation of the third motor; the other end of the drive rod is fixedly connected to the limiting frame so that the limiting frame can be extended or retracted by the movement of the drive rod so as to move the limiting frame into or out of the space between adjacent battery packs.

[0008] Preferably, the base frame includes a pair of side frames, a central frame, and a pair of sealing frames; the pair of side frames are fixedly connected to both sides of the central frame, and the sealing frames are bolted to both ends of the pair of side frames and the central frame; the transport device is fitted around the outside of the central frame; a stabilizing groove is provided on the side of the side frame near the central frame, and a power groove is formed between the side frame and the sealing frame, and a limit groove is also provided on the groove wall of the power groove.

[0009] Preferably, the transport device includes at least one first motor disposed in the power slot, a pair of rotating components and a track assembly; the two ends of the center frame are recessed to accommodate the rotating components, the rotating components extend into the power slot and are fixedly connected to the drive end of the first motor; the track assembly is sleeved on the pair of rotating components and the outer wall of the center frame, and the outer wall of the rotating components is provided with a rack to mesh with the track assembly.

[0010] Preferably, the track assembly is bolted with multiple limiting rods, which are equidistant from each other, and the spacing between adjacent limiting rods matches the battery pack; the track assembly extends further on both sides to insert into the stabilizing groove.

[0011] Preferably, multiple mounting slots are provided on a pair of side frames, and multiple rotating rollers are rotatably connected in each mounting slot; the lower ends of both sides of the movable housing are respectively fixedly connected to toothed parts and roller parts, and are located in sliding slots provided on the pair of side frames; a power component is fixedly connected in the power slot, and is connected to the toothed parts through the engagement of the power component.

[0012] Preferably, any one of the side frames is also provided with a drive groove with a "convex" cross-section for installing a third motor. One end of the drive rod extends into the protruding end of the drive groove, and the width of the drive rod matches the protruding end of the drive groove.

[0013] Preferably, the limiting frame includes a pair of isolation rods, multiple pairs of telescopic members, and multiple pairs of stabilizing plates; the two ends of the multiple pairs of telescopic members are respectively fixedly connected to a pair of isolation rods; each pair of stabilizing plates is respectively disposed on both sides of each pair of telescopic members and is slidably connected to the telescopic members; the upper side of each pair of stabilizing plates is fixedly connected to the top side inside the fixed housing and the movable housing, and the lower side is used to contact the battery pack.

[0014] Preferably, each isolation rod has multiple partition slots equidistantly spaced between its two ends to match the battery pack, thus forming multiple isolation segments. The width of each isolation segment matches the width of the limiting rod and the drive rod. The drive rod is fixedly connected to any one of the isolation segments. Limiting segments are also fixedly connected to both sides of each isolation segment.

[0015] Preferably, each pair of telescopic components includes a pair of telescopic plates and a rotating shaft, with the pair of telescopic plates meshing with the upper and lower sides of the rotating shaft; each pair of telescopic plates is fixedly connected to a pair of isolation sections of a pair of isolation rods; the two sides of the telescopic plates are slidably connected to a corresponding pair of stabilizing plates, and the two ends of the rotating shaft are rotatably connected to a corresponding pair of stabilizing plates.

[0016] Preferably, multiple support rods are threaded to the underside of each stabilizing plate to extend the height of the stabilizing plate and limit the battery packs of different heights.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Installing a mobile battery pack loading mechanism inside the container improves loading efficiency: through the cooperation of the tracked and rotating components, the loaded battery packs can be transported to the fixed container shell, and then ready for transport of new battery packs through the loading port; the loading port position remains fixed and does not require alignment, allowing battery packs to be directly delivered to the tracked components, optimizing the loading process and making loading more convenient and faster. No additional equipment is needed for transportation; lifting equipment can be used, which also reduces costs and improves space utilization.

[0019] The limiting device improves stability and safety during transportation: the isolation section is embedded between adjacent battery packs to prevent the battery packs from moving left and right, and the telescopic plate can be adjusted according to the size of the battery pack to keep the limiting section in close contact with the battery pack; the combination of the stabilizing plate and the support rod can limit the top of the battery pack, thereby preventing the battery pack from colliding during transportation and avoiding the risks caused by vibration.

[0020] By combining track components, limiting devices, and limiting rods, not only can the packing efficiency be improved, but the unloading efficiency can also be improved. Lifting equipment can be used to remove the battery pack from the loading port. Attached Figure Description

Detailed Implementation

[0041] Example 1

[0042] Please see Figures 1-19 The present invention provides a technical solution: such as Figures 1-5 As shown, a mobile battery energy storage container includes a base frame 1, a fixed shell 2, a movable shell 3, at least one battery pack 4, a transport device 5, and a limiting device 6. The fixed shell 2 and the movable shell 3 are both mounted on the base frame 1, with the fixed shell 2 fixedly connected to the base frame 1 and the movable shell 3 slidably connected to the base frame 1. The battery pack 4 is placed on the transport device 5, which is fitted around the outside of the base frame 1 to rotate cyclically on the outer wall of the base frame 1, thus moving the battery pack 4. The limiting device 6 is located on the inner top of the fixed shell 2 and the movable shell 3, and is used to embed between adjacent battery packs 4 to restrict the swaying of the battery pack 4. Multiple baffles 21 are fixedly connected to both the side of the fixed shell 2 away from the movable shell 3 and the side of the movable shell 3 away from the fixed shell, to restrict the lateral movement of the entire battery pack 4 (i.e., movement along the length of the fixed shell 2).

[0043] like Figures 6-12 As shown, the base frame 1 includes a pair of side frames 11, a central frame 12, and a pair of sealing frames 13; the pair of side frames 11 are fixedly connected to both sides of the central frame 12, and the sealing frames 13 are bolted to both ends of the pair of side frames 11 and the central frame 12. The transport device 5 is fitted onto the outside of the central frame 12. A stabilizing groove 111 is provided on the side of the side frame 11 closest to the central frame 12, and a power groove 112 is formed between the side frame 11 and the sealing frames 13. A limiting groove 113 is also provided on the groove wall of the power groove 112.

[0044] The sealing frame 13 includes a pair of sealing blocks 131 and a sealing plate 132. Each sealing block 131 corresponds to the end of the side frame 11 to form a power groove 112. The sealing plate 132 has an L-shaped cross section, and its two ends are fixedly connected to the pair of sealing blocks 131 respectively.

[0045] The transport device 5 includes at least one first motor 51, a pair of rotating components 52, and a track assembly 53. The first motor 51 is fixedly connected to the power groove 112. The two ends of the center frame 12 are recessed to accommodate the rotating components 52. The rotating components 52 extend into the power groove 112 and are placed in the limiting groove 113, which restricts the displacement of the rotating components 52. The drive end of the first motor 51 is fixedly connected to the end of the rotating components 52 to drive the rotating components 52 to rotate. The track assembly 53 is fitted onto the pair of rotating components 52 and the outer wall of the center frame 12. The outer wall of the rotating components 52 is provided with a rack to mesh with the track assembly 53, thereby driving the track assembly 53 to rotate cyclically. Multiple limiting rods 531 are bolted to the track assembly 53. The multiple limiting rods 531 are equidistantly arranged, and the spacing between adjacent limiting rods 531 matches the battery pack 4. The two sides of the track assembly 53 extend further to insert into the stabilizing groove 111 so that the track assembly 53 can move stably on the center frame 12. The distance between the vertical portion of the blocking plate 132 and the track assembly 53 is matched with the height of the limiting rod 531, so that the limiting rod 531 can rotate smoothly with the track assembly 53. The track assembly 53 can adopt existing technologies, such as track-like mechanisms, which will not be described in detail here.

[0046] Each rotating assembly 52 includes a power roller 521 and a pair of rotating disks 522. The power roller 521 is located at both ends of the central frame 12, and both ends of the power roller 521 extend into the power groove 112 and are fixedly connected to the rotating disks 522. The drive end of the first motor 51 is fixedly connected to the rotating disks 522, and the rotating disks 522 are correspondingly embedded in the limiting grooves 113 and rotate with the first motor 51.

[0047] The track assembly 53 includes multiple track plates 532, which are rotatably connected to each other, and a limit rod 531 is bolted to the track plates 532.

[0048] Multiple mounting slots 114 are provided on a pair of side frames 11, and multiple rotating rollers 14 are rotatably connected in each mounting slot 114. The rotating rollers 14 are flush with the upper side of the side frame 11 to reduce the resistance to the movement of the battery pack 4.

[0049] The lower ends of both sides of the movable housing 3 are respectively fixedly connected to toothed parts and roller parts, and a pair of sliding grooves 115 are provided on a pair of side frames 11 corresponding to the toothed parts and roller parts (see Figure 10 Within the power groove 112 located below the teeth, a toothed ring groove communicating with the sliding groove 115 is also provided. A second motor 71 is fixedly connected within the power groove 112, and a toothed ring 72 matching the toothed ring groove is fixedly connected to the drive end of the second motor 71. The toothed ring 72 meshes with the teeth at the lower end of the movable housing 3, so that the rotation of the second motor 71 drives the toothed ring 72 to rotate, thereby causing the teeth and the movable housing 3 to move in the same direction along the sliding groove 115. The second motor 71 and the toothed ring 72 constitute the power component.

[0050] like Figures 13-19 and Figure 2-5 As shown, the limiting device 6 includes a third motor 61, a drive rod 62, and a limiting frame 63. Each side frame 11 has a convex drive groove 116 for mounting the third motor 61. One end of the drive rod 62 extends into the convex end of the drive groove 116, and the width of the drive rod 62 matches the convex end of the drive groove 116. The drive end of the third motor 61 extends towards the drive rod 62 and is threadedly connected to the drive rod 62, so that the rotation of the third motor 61 drives the drive rod 62 to move. The other end of the drive rod 62 is fixedly connected to the limiting frame 63. The movement of the drive rod 62 causes the limiting frame 63 to extend and retract. By retracting, the limiting frame 63 moves between adjacent battery packs 4 to prevent collisions between the battery packs 4.

[0051] The limiting frame 63 includes a pair of isolation rods 631, multiple pairs of telescopic members 632, and multiple pairs of stabilizing plates 633. The two ends of the multiple pairs of telescopic members 632 are fixedly connected to a pair of isolation rods 631, so that the pair of isolation rods 631 can move in the same direction to between adjacent battery packs 4 or move out of the battery pack 4 in the opposite direction. Each pair of stabilizing plates 633 is respectively disposed on both sides of each pair of telescopic members 632 and is slidably connected to the telescopic members 632 to prevent deformation of the telescopic members 632. The upper side of each pair of stabilizing plates 633 is fixedly connected to the top inside of the fixed housing 2 and the movable housing 3, and the lower side is used to contact the battery pack 4 to restrict the movement of the battery pack 4. Alternating grooves 8 for matching the isolation rods 631 are also provided on both sides inside the fixed housing 2 and the movable housing 3 for placing the isolation rods 631 that have been removed from the battery pack 4.

[0052] Each isolation rod 631 has multiple equally spaced partition slots 6311 between its two ends, forming multiple isolation segments 6312. The partition slots 6311 are matched with the battery packs 4. The width of the isolation segment 6312 matches the width of the limiting rod 531 and the drive rod 62, allowing the isolation segment 6312 to move in or out of the gap between adjacent battery packs 4. The drive rod 62 is fixedly connected to the lower end of any isolation segment 6312. The movement of the drive rod 62 drives the telescopic member 632 to extend and retract. Preferably, the drive rod 62 is fixedly connected to the lower end of the isolation segment 6312 located in the middle, so that the isolation rod 631 is subjected to balanced force. Limiting segments 634 are also fixedly connected to both sides of the isolation segment 6312 to restrict the movement of the battery packs 4 toward the sides of the fixed housing 2.

[0053] Each pair of telescopic components 632 includes a pair of telescopic plates 6321 and a rotating shaft 6322. The pair of telescopic plates 6321 are engaged with the upper and lower sides of the rotating shaft 6322. Each pair of telescopic plates 6321 is fixedly connected to a pair of isolation sections 6312 of a pair of isolation rods 631, so that the upper and lower telescopic plates 6321 can move synchronously. Each pair of telescopic components 632 corresponds to a pair of stabilizing plates 633. The two sides of the telescopic plates 6321 are slidably connected to the pair of stabilizing plates 633, and the two ends of the rotating shaft 6322 are rotatably connected to the pair of stabilizing plates 633.

[0054] The limiting device 6 also includes two fixing rods 64. Each stabilizing plate 633 has at least one pair of sliding openings 6331 corresponding to the two fixing rods 64. One fixing rod 64 passes through the sliding opening 6331 and is fixedly connected to the lower telescopic plate 6321, while the other fixing rod 64 passes through the sliding opening 6331 and is fixedly connected to the upper telescopic plate 6321. The height of the fixing rod 64 matches the diameter of the rotating shaft 6322, allowing the fixing rod 64 to move synchronously with the telescopic plate 6321. Multiple support rods 6332 are also threaded onto the lower side of each stabilizing plate 633 to extend the height of the stabilizing plate 633 and limit the battery pack 4 at different heights.

[0055] Working principle: First, a loading port is opened between the movable housing 3 and the fixed housing 2 for loading the battery pack 4. Specifically, the operator starts the second motor 71, which rotates the gear ring 72, thereby moving the movable housing 3 away from the fixed housing 2 until the distance between the movable housing 3 and the fixed housing 2 is greater than the width of the battery pack 4, and this point is defined as the loading port.

[0056] Next, the limiting rods 531 are moved to the loading port, and the battery pack 4 is placed between a pair of limiting rods 531. Specifically, the operator starts the first motor 51, which rotates the rotating disk 522, the power roller 521, and moves the track assembly 53, causing the track assembly 53 to move towards the fixed housing 2 until any one of the limiting rods 531 is aligned with the stabilizing plate 633 closest to the moving housing 3, that is, the limiting rod 531 and the stabilizing plate 633 are on the same horizontal plane facing the moving housing 3. Then, the first motor 51 is turned off. The pair of limiting segments 634 closest to the moving housing 3 is defined as the starting limiting segments 634. The battery pack 4 is lifted and lowered between the pair of starting limiting segments 634 using a hoisting device. The battery pack 4 continues to move down until it lands on the track assembly 53. At this point, the battery pack 4 is located between the pair of limiting rods 531, completing the loading of the battery pack 4. Then, the first motor 51 is restarted to drive the track assembly 53 to continue moving toward the fixed housing 2 until the next limit bar 531 is aligned with the stabilizing plate 633 closest to the moving housing 3. The first motor 51 is then turned off again, and the new battery pack 4 is hoisted onto the track assembly 53 again in the same way. This process is repeated until the last battery pack 4 is hoisted between the pair of limit bars 531 at the loading port, completing the hoisting. At this time, all battery packs 4 are located under the stabilizing plate 633, which restricts the up-and-down swaying of the battery packs 4.

[0057] Next, the hoisted battery pack 4 is positioned to prevent swaying during transport. Specifically, the operator starts the third motor 61. The rotation of the third motor 61 causes the drive rod 62 to move in the direction of the third motor 61, which in turn causes the isolation section 6312 to move in the same direction as the corresponding telescopic plate 6321. This causes the telescopic plate 6321 on the opposite side and the isolation section 6312 to move towards each other, thus moving the isolation section 6312 between adjacent battery packs 4 to prevent lateral swaying. It also causes the limiting section 634 to fit against both sides of the corresponding battery pack 4 to prevent forward and backward movement. The third motor 61 is then turned off.

[0058] Finally, the operator restarts the second motor 71, which rotates in the opposite direction, thereby resetting the movable housing 3 and closing the loading port. This ensures that the abutment plates 21 inside the fixed housing 2 and movable housing 3 contact both sides of the loaded battery pack, preventing the battery pack 4 from moving (see...). Figure 19 ).

[0059] During unloading, the specific operation is as follows: First, move the movable housing 3 to open the loading port, the specific operation is the same as above, and will not be repeated. Then, the operator starts the first motor 51, which drives the track assembly 53 and the limit rod 531 to move away from the fixed housing 2 until the stabilizing plate 633 closest to the movable housing 3 is aligned with the corresponding limit rod 531 on the lower side. At this time, the isolation rod 631, the isolation section 6312 and the limit section 634 move into the clearance groove 8. Then, turn off the first motor 51, and the battery pack 4 can be moved upward by the hoisting equipment to lift the battery pack 4 out. Repeat this operation until all battery packs 4 are lifted out.

[0060] If the height of the battery pack 4 becomes too low, the support rod 6332 can be rotated from the underside of the stabilizing plate 633 to the top of the battery pack 4 to adapt to the height of the battery pack 4.

[0061] During loading, the battery pack 4 can also be placed on the track assembly 53 from the side of the loading port. The specific operation is as follows: The operator first opens the loading port, then starts the first motor 51 and moves the limiting rods 531 on the track assembly 53 until any one of the limiting rods 531 is aligned with the starting limiting segment 634, i.e., the side of the limiting rod 531 and the limiting segment 634 facing the moving housing 3 is on the same plane. Then, the first motor 51 is turned off. Next, a hoisting device is used to move the battery pack 4 from the side of the loading port onto the track assembly 53. Then, the first motor 51 is started again and moves the track assembly 53 and the limiting rods 531 on the track assembly 53 in the same direction until the next limiting rod 531 is aligned with the starting limiting segment 634. The first motor 51 is then turned off, and the new battery pack 4 is placed on the track assembly 53. Repeat this process until battery pack 4 is placed on the loading port. Then, start the first motor 51 and move the track assembly 53 until battery pack 4 on the loading port moves to the underside of the stabilizing plate 633 closest to the moving housing 3. Then, turn off the first motor 51. Finally, close the loading port.

[0062] During unloading, the battery pack 4 can also be removed from the side. The specific operation is as follows: open the loading port, start the first motor 51, and drive the track assembly 53 to move towards the moving housing 3, so that the battery pack 4 at the loading port moves to the left side of the starting limit section 634. The lifting equipment can then be used to remove the battery pack 4 from the side of the loading port. The operation for removing the remaining battery packs 4 is the same as above.
