Description

Technical Field

[0001] This utility model relates to the field of battery pack loading technology, specifically to a battery pack loading device for lithium battery energy storage containers. Background Technology

[0002] Currently, an increasing number of manufacturers are replacing traditional 48 kWh battery packs with 96 kWh battery packs. This results in the battery pack length increasing from 1 meter to 2 meters and the weight increasing from 310 kg to 600 kg. This causes the deformation of the traditional forklift structure in the Z-axis to far exceed the requirements of traditional structures. Simultaneously, in order to fit more battery packs into the same volume, the spacing between battery pack layers is also decreasing, making traditional forklift loading mechanisms unable to meet current production needs. Therefore, the industry urgently needs a low-deflection or zero-deflection device that can frictionlessly deliver battery packs into energy storage containers. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a lithium battery energy storage container battery pack loading device that transforms the cantilever beam structure of traditional forks into a simply supported beam structure, thereby reducing fork deformation.

[0004] To address the aforementioned technical problems, this utility model provides a lithium battery energy storage container battery pack loading device, including a bidirectional fork. The bidirectional fork includes a fork rail and a fork drive mechanism. A sliding bar is provided on the fork rail. The fork drive mechanism is used to control the sliding bar to extend into the container. An auxiliary support mechanism is provided at one end of the sliding bar extending into the container. The auxiliary support mechanism includes a support drive mechanism and a support arm. One end of the support arm is connected to the output end of the support drive mechanism, and the other end of the support arm is used for sliding or rolling support on the battery pack bracket of the next layer.

[0005] In some embodiments, a support wheel is provided at the other end of the support arm.

[0006] In some embodiments, a plurality of transition wheels are rotatably arranged on the side of the slide bar, and transition belts are arranged on the plurality of transition wheels.

[0007] In some embodiments, two auxiliary support mechanisms are symmetrically arranged.

[0008] In some embodiments, two fork rails are arranged in parallel, and a connecting frame is connected between the slide bars on the two fork rails. The auxiliary support mechanism is fixedly installed on the connecting frame.

[0009] In some embodiments, the support drive mechanism includes a support motor and a reducer, the support motor and the reducer being fixed to the bottom of the connecting frame, and the support motor being connected to the support arm via the reducer.

[0010] In some embodiments, the bidirectional forks are mounted on a servo control frame, which is used to control the bidirectional forks to move to the position corresponding to the battery pack bracket.

[0011] In some embodiments, the servo control frame includes a traveling base, on which a slide is slidably disposed, and on which a lateral drive mechanism is disposed, the lateral drive mechanism being used to control the slide to move on the traveling base, so that the bidirectional forks move to different compartments.

[0012] In some embodiments, a lifting frame is provided on the slide, and multiple lead screws are rotatably arranged on the lifting frame. The bidirectional forks are threadedly connected to the lead screws, and a lifting drive mechanism is provided on the top of the lifting frame.

Detailed Implementation

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] like Figure 1 As shown, this utility model provides a battery pack loading device for a lithium battery energy storage container. The battery pack loading device is used to place the battery pack 2 on the battery pack support 11 of the container 1. The container 1 is fixed on the temporary storage rack 3. Multiple rows of supports are provided inside the container 1. Every two rows of supports are used to place one row of battery pack 2. One row of battery pack 2 is a battery cluster.

[0026] like Figure 2 As shown, the lithium battery energy storage container battery pack loading equipment includes a bidirectional fork 4, which includes a fork slide rail 41 and a fork drive mechanism. A slide bar 42 is provided on the fork slide rail 41. The fork drive mechanism is used to control the slide bar 42 to extend into the container 1. The fork drive mechanism can be a motor. The fork drive mechanism is fixed on the slide bar 42. A rack is provided on the fork slide rail 41. The fork drive mechanism meshes with the rack, thereby driving the slide bar 42 to slide along the fork slide rail 41.

[0027] An auxiliary support mechanism is provided at one end of the sliding strip 42 that extends into container 1, such as... Figure 5 , 6 As shown, the auxiliary support mechanism includes a support drive mechanism and a support arm 46. One end of the support arm 46 is connected to the output end of the support drive mechanism, and the other end of the support arm 46 is used for sliding or rolling support on the battery pack bracket 11 of the next layer. The other end of the support arm 46 can be provided with a support wheel 47, and the support arm 46 is supported by the support wheel 47.

[0028] It is understandable that, such as Figure 5 As shown, Figure 5The diagram illustrates a three-layer battery pack support 11. The battery pack 2 located on the bidirectional fork 4 needs to be placed on the current layer (i.e., the second layer) of the battery pack support 11. When one end of the slide bar 42 with the auxiliary support mechanism just moves into the container 1, the cantilever length of the slide bar 42 is relatively short and will not produce large deformation. The support drive mechanism can control the support arm 46 to rotate, so that the support arm 46 supports the next layer (i.e., the first layer) of the battery pack support 11, supporting the cantilever end of the slide bar 42, so that the cantilever beam structure of the slide bar 42 is transformed into a simply supported beam structure. As the slide bar 42 continues to move forward, the support drive mechanism can always control the support arm 46 to support the slide bar 42, ensuring that the slide bar 42 and the battery pack 2 on it always remain in a horizontal state. When the battery pack 2 moves into place, the support drive mechanism controls the support arm 46 to reverse while the bidirectional fork 4 descends, which can ensure that the battery pack 2 falls horizontally and smoothly onto the battery pack support 11 of the second layer.

[0029] Furthermore, two auxiliary support mechanisms are symmetrically arranged to ensure stable support for the ends of the slide bar 42.

[0030] In some embodiments, two fork rails 41 are arranged in parallel, such as... Figure 5 As shown, a connecting frame 43 connects the slide bars 42 on the two fork rails 41, and an auxiliary support mechanism is fixedly installed on the connecting frame 43. The support drive mechanism includes a support motor 44 and a reducer 45. The support motor 44 and the reducer 45 are fixed to the bottom of the connecting frame 43 by bolts, and the support motor 44 is connected to the support arm 46 through the reducer 45.

[0031] To facilitate the placement of the battery pack 2 on the bidirectional fork 4, in some embodiments, multiple transition wheels 48 are rotatably arranged on the side of the slide bar 42, and transition belts 49 are arranged on the multiple transition wheels 48. The transition wheels 48 can be arranged on opposite sides of two slide bars 42, and the transition belts 49 are wound around the multiple transition wheels 48. When the battery pack 2 is pushed into the bidirectional fork 4, friction can be reduced, making it easier to push the battery pack 2 in.

[0032] To improve the automation of battery pack 2 loading, in some embodiments, bidirectional forks 4 are mounted on a servo control frame. The servo control frame is used to control the bidirectional forks 4 to move to the position corresponding to the battery pack support 11. That is, the servo control frame can control the bidirectional forks 4 to move to different layers (i.e., different compartments) corresponding to different battery clusters.

[0033] like Figure 2As shown, the servo control frame includes a traveling base 5, which is fixed to the ground by expansion screws. A slide block 6 is slidably mounted on the traveling base 5. A rack is mounted on the side of the traveling base 5. A transverse drive mechanism 7 is mounted on the slide block 6. The transverse drive mechanism 7 is a motor. The output end of the transverse drive mechanism 7 meshes with the rack to control the slide block 6 to move on the traveling base 5, so that the bidirectional forks 4 can move to different compartments.

[0034] like Figure 2 As shown, a lifting frame 8 is mounted on the slide block 6, and multiple lead screws 9 are rotatably mounted on the lifting frame 8. The bidirectional forks 4 are threadedly connected to the lead screws 9. A lifting drive mechanism 10 is mounted on the top of the lifting frame 8. The lifting drive mechanism 10 uses a motor and is used to control the rotation of the lead screws 9, thereby controlling the lifting and lowering of the bidirectional forks 4. Mounting plates are mounted on both sides of the bidirectional forks 4, and threaded sleeves are fixedly mounted on the mounting plates. The threaded sleeves are fitted onto the lead screws 9. During the rotation of the lead screws 9, the threaded sleeves will move along the lead screws 9, thereby causing the mounting plates and the bidirectional forks 4 on them to move along the lead screws 9.

[0035] In some embodiments, two lead screws 9 are provided, and both lead screws 9 are driven by a single lifting drive mechanism 10, or two lifting drive mechanisms 10 are used respectively. When a single lifting drive mechanism 10 is used, the lifting drive mechanism 10 is located at the top center of the lifting frame 8, and transmission boxes are symmetrically arranged on both sides of the lifting drive mechanism 10. A bevel gear is provided at the output end of the lifting drive mechanism 10, and a transmission rod is provided between the lifting drive mechanism 10 and the lead screw 9. Bevel gears are provided at both ends of the transmission rod, and a bevel gear is provided at the top end of the lead screw 9. The bevel gears of the lifting drive mechanism 10 and the lead screw 9 respectively mesh with the bevel gears of the transmission rod, thereby realizing the simultaneous driving of two lead screws 9 by one lifting drive mechanism 10. Similarly, when four lead screws 9 are provided, one lifting drive mechanism 10 can also be used for driving, such as... Figure 2 As shown.

[0036] The servo control frame of this utility model can adopt the walking mechanism and lifting mechanism disclosed in Chinese invention patent application with publication number CN119735135A.

[0037] The working principle of the lithium battery energy storage container's battery pack loading equipment is as follows:

[0038] The battery pack 2 is manually hoisted onto the slide bar 42 of the double-sided fork 4. Then, the lifting frame 8 is manually controlled to align the battery pack 2 with the desired storage position in container 1. The slide bar 42 of the double-sided fork 4 is manually moved into container 1. Once the support wheel 47 is fully inside container 1, the support motor 44 rotates, causing the support arm 46 and support wheel 47 to swing downwards until the support wheel 47 contacts and supports the battery pack bracket 11 on the next layer. This process completes the end support work for the double-sided fork 4. Then, the slide bar 42 continues to move into container 1. Under the support of the support wheel 47, the entire double-sided fork 4... The battery pack 2 will not deform and will be smoothly transported to the set position. This process is precisely controlled by the fork drive mechanism. After the battery pack 2 is in place, the support motor 44 reverses, causing the support arm 46 and support wheel 47 to swing upward. At the same time, the lifting frame 8 controls the bidirectional fork 4 to descend. This process is controlled by the fork drive mechanism and the lifting drive mechanism 10 to keep the bidirectional fork 4 horizontal and descend slowly, so that the battery pack 2 lands on the battery pack bracket 11. The slide bar 42 detaches from the lower surface of the battery pack 2 and returns to its initial position. During this process, the support wheel 47 retracts to a horizontal position. At this point, one cycle ends. The next cycle repeats the action, placing the battery pack 2 from the next layer in the box.
