Description

Technical Field

[0001] This utility model relates to the field of sodium-ion battery pack technology, and in particular to a sodium-ion battery pack that is easy to disassemble. Background Technology

[0002] Sodium-ion batteries are rechargeable batteries that primarily rely on the movement of sodium ions between the positive and negative electrodes to function. They store and release electrical energy through the transfer of sodium ions. Sodium-ion batteries can be classified into cylindrical batteries, button batteries, multilayer batteries, and plate batteries, all of which are rechargeable. Multiple sodium-ion batteries are installed together to form a battery pack, which is called a sodium-ion battery pack.

[0003] During the use of sodium-ion battery packs, one of the batteries may become damaged. When replacing the battery, it is necessary to disassemble the battery box to replace the individual battery. Traditional battery box disassembly is too cumbersome and cannot quickly and effectively replace individual batteries. Utility Model Content

The outer surface of the vertical guide rods is sleeved with a limiting movable sleeve. The bottom end of the clamping rod sleeve abuts against the top end of the limiting movable sleeve.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a rectangular connecting piece, which is bolted to the upper surface of the battery junction box. A T-shaped positioning frame is fixedly connected to one side of the rectangular connecting piece. Multiple positioning rods are fixedly connected to the side wall of the T-shaped positioning frame. The positioning rods are engaged with corresponding U-shaped positioning frames. Positioning holes corresponding to the positioning rods are provided on the side wall of the U-shaped positioning frame.

[0010] As a further description of the above technical solution:

[0011] The reinforcing assembly includes a mounting reinforcement frame disposed on the top of the battery box cover. The four ends of the mounting reinforcement frame are respectively sleeved on the outer surfaces of four positioning connecting rods. The top outer surface of the positioning connecting rods is threaded with a locking nut, and the locking nut abuts against the upper surface of the end of the mounting reinforcement frame.

[0012] As a further description of the above technical solution:

[0013] Both sides of the mounting reinforcement frame are fixedly connected to a connecting shaft, and the outer surface of the connecting shaft is rotatably connected to a movable sleeve rod, and the outer surface of the movable sleeve rod is fixedly connected to an operating handle.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this easily disassembled sodium-ion battery pack allows for vertical upward movement of the battery junction box, separating the four positioning lugs from the four vertical guide rods. The battery junction box can then be removed from the battery housing. Loosening the removal bolts separates the rectangular connecting piece from the upper surface of the battery junction box. The T-shaped positioning bracket then separates from the corresponding U-shaped positioning bracket, allowing the U-shaped positioning bracket to be removed. This frees up the sodium-ion battery body, enabling easy replacement of any missing battery. The operation is convenient.

[0020] 2. Compared with the prior art, this easy-to-disassemble sodium-ion battery pack has an operating handle that makes it easy to remove the mounting reinforcement frame and facilitates the handling of the battery box. The mounting reinforcement frame can strengthen the battery box and increase its compressive strength. Attached Figure Description
