Description

Technical Field

[0001] This utility model relates to the field of lithium battery packaging device technology, and in particular to a soft-pack lithium battery packaging frame. Background Technology

[0002] The pouch lithium battery packaging frame is a protective structure specifically designed for pouch lithium batteries. It aims to improve the safety and stability of batteries during transportation, storage, and use through rigid support and modular design, providing reliable external protection for high-energy-density lithium batteries.

[0003] In the prior art, such as Chinese Publication No. CN210437729U, a utility model discloses a soft-pack lithium battery packaging frame, including several frame edges; the frame edges are fixedly connected at diagonal points to form a cuboid frame component; the frame edges are long strip-shaped components with right-angled cross-sections formed by folding rigid sheet metal; a further improvement is that: connectors are provided at diagonal points of the frame edges; the connectors are formed and embedded in the end grooves of the connected frame edges, and the two ends of the connectors are embedded in the connection holes of the connected frame edges; adhesive is provided in the connection holes of the frame edges. This utility model has a robust structure and effectively protects the soft-pack lithium battery.

[0004] While the above solutions have the advantages mentioned above, their disadvantage lies in the lack of an effective shock absorption structure for the packaging frame and the lithium battery body. During transportation, storage, and use, the soft-pack lithium battery packaging frame and the lithium battery body are easily subjected to vibration and shock from the external environment. Vibration may cause the internal structure of the battery to loosen, the electrode to deform, affecting the battery's performance and lifespan, and may even cause safety hazards such as short circuits. This reduces the stability and reliability of the lithium battery in complex environments, fails to meet the needs of practical applications, and poses a huge threat to safety. Utility Model Content

[0005] The purpose of this invention is to provide a packaging frame for soft-pack lithium batteries. This invention designs a structure that effectively dampens and buffers the vibrations and shaking experienced by the packaging frame and the lithium battery body. This prevents the soft-pack lithium battery packaging frame and the lithium battery body from being subjected to vibrations and shaking impacts from the external environment during transportation, storage, and use. It also prevents vibrations from causing loosening of the internal battery structure and deformation of the electrode sheets, thereby improving battery performance and lifespan, avoiding safety hazards such as short circuits, and enhancing the stability and reliability of lithium batteries in complex environments. This can meet the needs of practical applications and improve safety in use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a soft-pack lithium battery packaging frame, comprising:

[0007] The main protective plate of the frame, wherein multiple shock-absorbing dampers are fixedly installed on the bottom outer surface of the main protective plate, and further includes:

[0008] A base plate is fixedly mounted on the outer surface of the bottom of multiple shock-absorbing dampers. Multiple positioning holes are provided on the outer surface of the base plate. Buffer springs are fixedly mounted on the outer surfaces of the multiple shock-absorbing dampers, and these buffer springs are fixedly connected to the outer surface of the bottom of the main frame protective plate. Two connecting plates are fixedly mounted on the outer surface of the main frame protective plate. Multiple guide rods are slidably connected to the inner surfaces of the two connecting plates. The multiple shock-absorbing dampers extend and retract under vibration and sway. The shock-absorbing dampers generate a damping effect through internal hydraulic channels, converting collision kinetic energy into heat energy for dissipation, thus reducing the vibration and sway of the main frame protective plate and the lithium battery body. Simultaneously, the multiple buffer springs undergo elastic deformation under vibration and sway. The buffer springs store energy through compression deformation, further buffering the vibration and sway of the main frame protective plate and the lithium battery body.

[0009] Preferably, two rods are fixedly installed on the outer surface of the base plate, and the two rods are respectively fixedly connected to a plurality of guide rods, thereby fixing the plurality of guide rods.

[0010] Preferably, two limiting frames are fixedly installed on the inner surface of the main protective plate of the frame. The two limiting frames are symmetrically arranged on the inner surface of the main protective plate of the frame, and the two limiting frames limit the multiple lithium battery bodies.

[0011] Preferably, multiple insulating partitions are movably connected to the inner surfaces of the two limiting frames. Two flame-retardant polyurethane pads are fixedly installed on the bottom outer surfaces of each of the multiple insulating partitions. Multiple lithium battery bodies are movably connected to the opposite surfaces of the multiple insulating partitions. The insulating partitions between the multiple lithium battery bodies, together with the flame-retardant polyurethane pads, effectively isolate the positive and negative electrodes of adjacent lithium battery bodies, absorb the vibration and impact of the lithium battery bodies during transportation or use, and ensure the safe operation of the battery pack.

[0012] Preferably, the outer surface of the frame main protective plate is provided with multiple welding grooves, which are evenly arranged on the outer surface of the frame main protective plate. The multiple welding grooves connect the lithium battery body to the external circuit to ensure smooth current transmission.

[0013] Preferably, multiple side plates are fixedly provided on the outer surface of the main protective plate of the frame, and rotating frames are rotatably connected to the outer surfaces of the multiple side plates, with the multiple side plates mounting the multiple rotating frames.

[0014] Preferably, each of the multiple rotating frames has a sleeve fixedly provided on its outer surface, and each of the multiple sleeves has a screw threadedly connected to its inner surface, with the multiple sleeves limiting the movement of the multiple screws.

[0015] Preferably, a knob is fixedly provided on the top outer surface of each of the plurality of screws, and a fastening plate is fixedly provided on the bottom outer surface of each of the plurality of screws. By rotating the screws with the knobs, the multiple fastening plates are moved down to contact the insulating partitions, thereby fastening and fixing the multiple insulating partitions in place.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] This invention features a device with an effective shock absorption and buffer structure for the packaging frame and the lithium battery body, preventing the soft-pack lithium battery packaging frame and the lithium battery body from being subjected to vibration and shaking impacts from the external environment during transportation, storage, and use. This avoids vibration causing loosening of the internal structure and deformation of the electrode sheets, improves the performance and lifespan of the lithium battery, avoids safety hazards such as short circuits, and enhances the stability and reliability of the lithium battery in complex environments. It can meet the needs of practical applications and improve the safety of use. Attached Figure Description
