Description

Technical Field

[0001] The utility model relates to the technical field of ternary battery packs, in particular to a quick-detachable ternary battery pack protective shell. Background Art

[0002] A ternary polymer lithium battery refers to a lithium battery whose positive electrode material uses lithium nickel cobalt manganese oxide (Li(NiCoMn)O2) or lithium nickel cobalt aluminum oxide as a ternary positive electrode material. The ternary composite positive electrode material is made of nickel salt, cobalt salt and manganese salt as raw materials.

[0003] Before using the ternary battery pack, it is necessary to place the ternary battery pack inside a protective shell for fixing, and then use the ternary battery pack through the protective shell. The protective shell of the existing ternary battery pack is sealed by fasteners and buckles after the ternary battery is placed inside the protective shell. When the ternary battery pack inside needs to be inspected or repaired, it needs to be disassembled with tools, which is time-consuming and labor-intensive and reduces work efficiency. The wear caused by long-term use of the buckle connection will reduce the service life of the protective shell.

[0004] Furthermore, the existing ternary battery pack protective shell cannot limit the position of the ternary battery pack according to the size of the ternary battery pack. When one of the ternary batteries in the ternary battery pack is removed, it is difficult to continue to use the ternary battery pack. Utility Model Content

[0005] The purpose of the utility model is to provide a quick-detachable ternary battery pack protective shell to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a quick-release ternary battery pack protective shell, comprising a shell, a shell cover and a disassembly plate, the top of the shell is connected to the shell cover in an embedded manner, the inner wall of the shell is provided with a fixing groove, the inside of the fixing groove is slidably connected with the disassembly plate, one side of the disassembly plate is provided with a limiting plate, one side of the shell cover is fixedly connected to a support column, the end of the support column away from the shell is provided with a connecting block, one side of the connecting block is fixedly connected with an insertion block, one end of the insertion block is connected to the outer wall of the shell in an embedded manner, the insertion block passes through the shell cover, and a ternary battery is arranged inside the shell.

[0007] Preferably, one end of the support column away from the shell is connected to one end of the telescopic column in an embedded manner, and one end of the telescopic column away from the support column is connected to one side of the connecting block through a fastener, and a connecting port is opened on the top of the shell cover.

[0008] Preferably, an elastic member is provided inside the support column, one end of the elastic member is connected to the support column via a fastener, and one end of the elastic member away from the support column is connected to the telescopic column via a fastener.

[0009] Preferably, a slide groove is provided on one side of the shell cover, and the slide groove is connected to one end of the card block in a sliding manner, and the end of the card block away from the slide groove passes through and is connected to the handle.

[0010] Preferably, one side of the handle is connected to the shell cover via a fastener, a rubber pad is fixedly connected to the inner wall of the handle, and the handle is distributed on the shell cover in a mirror-image manner.

[0011] Preferably, the inner wall of the shell is provided with limiting grooves, the limiting grooves are distributed at equal intervals, the limiting grooves are connected to the limiting plate in a sliding manner, and the disassembly plate is provided with hidden buckles.

[0012] Preferably, the insertion block is in an oblique angle, and insertion blocks are respectively provided on both sides of the shell cover, and the end of the clamping block close to the sliding groove is trapezoidal.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model can quickly disassemble the ternary battery protective shell by providing a disassembly plate and an insertion block. When the shell needs to be disassembled, the card block is pushed upward, one end of the card block slides inside the slide groove, and the other end moves out of the inside of the grip, and then the grip is pushed obliquely downward on both sides. The movement of the grip drives the insertion block to move, and the movement of the insertion block drives the telescopic column to move through the connecting block. The movement of the telescopic column drives the elastic member to extend inside the support column until one end of the insertion block moves to the outside, and then the shell cover is lifted upward to open the shell, and then the disassembly plate is pulled through the fixed groove to the outside through the hidden buckle to complete the disassembly of the protective shell. No tools are required for disassembly, which is simple and fast, saves time and effort, and improves work efficiency. At the same time, it prevents the use of buckles from reducing their service life.

[0015] Secondly, the utility model can make the protective shell adapt to ternary battery packs of different sizes by setting a limit plate and a limit groove. When the damaged ternary battery in the ternary battery pack is removed, the ternary battery pack no longer fits the size of the protective shell. The limit plate is moved to the outside through the limit groove, and then the limit plate is moved to one side of the ternary battery pack, and enters the interior of the shell through the limit groove. The ternary battery pack is limited by the blocking of the limit plate to prevent the ternary battery pack from shaking in the protective shell. At the same time, the shell can adapt to ternary battery packs of different sizes, which reflects the practicality of this device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] When in use, when the shell 1 needs to be disassembled, first push the block 4 upwards, one end of the block 4 slides inside the slide groove 17, and the other end moves out of the handle 14, and then push the handle 14 obliquely downward on both sides, the movement of the handle 14 drives the insertion block 6 to move, the movement of the insertion block 6 drives the telescopic column 8 to move through the connecting block 5, and the movement of the telescopic column 8 drives the elastic member 15 to extend inside the support column 7 until one end of the insertion block 6 moves to the outside, and then lift the shell cover 2 upwards to open the shell 1, and then pull the disassembly plate 3 through the hidden buckle 12. The fixing groove 13 is moved to the outside to complete the disassembly of the protective shell. After the damaged ternary battery 9 in the ternary battery pack is removed, the ternary battery pack no longer fits the size of the protective shell. The limiting plate 10 is moved to the outside through the limiting groove 11, and then the limiting plate 10 is moved to one side of the ternary battery pack, and enters the interior of the shell 1 through the limiting groove 11.
