Abstract

This invention provides a rack, pinion, and roller-linked battery pack layering embedding mechanism. The mechanism includes a movable plate, one end of which is vertically fixedly connected to several support rods. A support frame is slidably fitted onto the surface of each support rod. Several fixed seats are fixedly connected to the front and rear sides of the upper surface of the support frame, and rotating wheels are rotatably mounted inside each fixed seat. This rack, pinion, and roller-linked battery pack layering embedding mechanism embeds the battery pack into the interior of an energy storage cabinet by moving it between multiple rotating wheels. After a single layer is embedded, a hoisting rope mechanism can be used to move the support frame up and down. After adjusting the support frame to the corresponding height of the cabinet layer, this process can be repeated to complete the layering embedding of the interior of the cabinet, thus improving the assembly efficiency of the energy storage cabinet.

The battery pack layered embedding mechanism with gear rack and roller linkage includes a movable plate 14. One end of the upper surface of the movable plate 14 is vertically fixedly connected to several support rods 20. The surface of the support rods 20 is slidably fitted with a support frame 1. Several fixed seats 2 are fixedly connected to the front and rear sides of the upper surface of the support frame 1.

[0022] The fixed base 2 has a rotating wheel 3 inside, and a limit plate 4 is fixedly connected to the outer end of the surface of the rotating wheel 3.

A support plate mechanism for fixing the moving plate 14 is provided on the surface of the counterweight 15.

[0024] In this embodiment, after the battery pack is placed between multiple rotating wheels 3, the limiting plate 4 limits the battery pack. Then, after the toothed plate mechanism works, it drives the connecting plate 7 to move. After the push plate 6 comes into contact with the surface of the battery pack, it can push the battery pack to move between multiple rotating wheels 3, thereby embedding the battery pack into the interior of the energy storage cabinet.

[0025] After a single layer is embedded, the support frame 1 can be moved up and down by the suspension rope mechanism. After the support frame 1 is moved to the corresponding height of the cabin layer, the operation can be repeated to complete the layered embedding work inside the cabin. The embedding work is simple and fast, which can improve the assembly efficiency of the energy storage cabinet.

Then, through the transmission of the second bevel gear 28, it can drive the rotating rod 23 to rotate. By rotating the winding roller 24, the connecting rope 25 can be released or wound up, thereby pulling the support frame 1 to move up and down. Example

[0038] Please refer to the image. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 Based on the same concept as the first embodiment described above, the support plate mechanism includes a fixed box 16, several electric telescopic rods 29 and a base plate 30, with the fixed box 16 fixedly connected to the upper surface of the counterweight block 15.

[0046] The working principle of the gear rack and roller linkage battery pack layer embedding mechanism provided by the present invention is as follows: After the battery pack is placed between multiple rotating wheels 3, the limiting plate 4 limits the battery pack. After the first motor 8 works, it drives the drive gear 9 to rotate. Through the meshing connection of the rack plate 12, it drives the connecting plate 7 to move along the surface of the receiving box 5. After the push plate 6 abuts against the surface of the battery pack, it pushes the battery pack to move between multiple rotating wheels 3, thereby embedding the battery pack into the interior of the energy storage cabinet. After the single-layer embedding is completed, the second motor 22 works, which drives the first bevel gear 27 to rotate. Through the transmission of the second bevel gear 28, it drives the rotating rod 23 to rotate. By rotating the winding roller 24, the connecting rope 25 is released or wound up, which pulls the support frame 1 to move up and down. After adjusting the support frame 1 to the corresponding height of the cabinet layer, the operation is repeated to complete the layer embedding work inside the cabinet.

[0047] Compared with related technologies, the battery pack layered embedding mechanism with gear rack and roller linkage provided by the present invention has the following advantages: After the battery pack is placed between multiple rotating wheels 3, the limiting plate 4 limits the battery pack. Then, the toothed plate mechanism drives the connecting plate 7 to move. After the push plate 6 abuts against the surface of the battery pack, the battery pack can be pushed to move between multiple rotating wheels 3, thereby embedding the battery pack into the interior of the energy storage cabinet. After a single layer is embedded, the supporting frame 1 can be lifted and moved by the hoisting rope mechanism. After the supporting frame 1 is moved to the corresponding height of the cabinet layer, the operation can be repeated to complete the layer embedding work inside the cabinet. The embedding work is simple and fast, which can improve the assembly efficiency of the energy storage cabinet. The multiple casters 17 facilitate the positioning of the device for assembling multiple energy storage cabinets. During the assembly process, the moving plate 14 can be fixed by the bracket mechanism, thereby improving the stability of the device during the layer embedding of the battery pack in the energy storage cabinet, which is beneficial to the assembly and use of the energy storage cabinet.
