Technical Field

[0001] The utility model relates to the field of ternary battery packs, in particular to a waterproof shell for a ternary battery pack. Background Art

[0002] Ternary battery is also known as ternary lithium battery. Ternary lithium battery refers to a lithium secondary battery that uses three transition metal oxides of nickel, cobalt and manganese as positive electrode materials. It fully integrates the good cycle performance of lithium cobalt oxide, the high specific capacity of lithium nickel oxide and the high safety and low cost of lithium manganese oxide. It uses molecular level mixing, doping, coating and surface modification methods to synthesize composite lithium-embedded oxides with synergistic effects of multiple elements such as nickel, cobalt and manganese.

[0003] First, the shell of the current ternary battery pack is already waterproof. A baffle is installed between the battery pack and the control component to avoid collision between the battery pack and the control component. However, the fixed installation of the baffle affects the disassembly and removal of the battery pack and is not convenient for the connection of the line.

[0004] Second, the middle part of the existing shell cover is weaker than the four corners, and is easily damaged in a collision, which is not convenient for protecting the battery pack. In addition, there is no limit assembly inside the shell, and the battery pack will shake inside the shell, which is easy to cause poor contact of the circuit. Utility Model Content

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] First, the utility model provides a waterproof shell for a ternary battery pack, which can facilitate the disassembly and installation of the ternary battery pack. During installation, the battery pack must be installed in the waterproof shell first, and then the clamping plate is inserted into the clamping groove, so that the cross bar on one side of the clamping plate limits and clamps the battery pack. The staff passes the line of the control panel through the wire groove of the clamping plate and then connects it to the battery pack. The wire groove facilitates the clamping and limiting of the line, avoids the displacement of the line and is also convenient for sorting the line. If disassembly is required, the staff disassembles the line connecting the control panel and the battery body, and then pulls the clamping plate out of the clamping groove on the inner wall of the waterproof shell, so that space is left on one side of the battery body for the staff to disassemble the battery pack from the inside of the waterproof shell.

At the same time, the limit frames reinforce the inner wall of the waterproof shell to prevent the waterproof shell from being damaged when it is hit. When the staff engages and docks the snap cover with the groove at the top of the waterproof shell, the rubber strip and the cross rod on the inner wall of the snap cover squeeze and clamp the battery body downward. The rubber strip has a certain elastic force, and rebounds when the squeezing disappears, so that the rubber strip is tightly adsorbed on the inner wall of the waterproof shell. At the same time, the cross rod on the inner wall of the upper cover is fitted and connected with the battery pack to limit the top of the battery pack. The staff uses bolts to penetrate the snap cover and enter the interior of the waterproof shell, so that the upper cover is tightly connected to the waterproof shell. The limit frames, cross rods, cross rods and other structures cooperate with each other to produce a multi-faceted fixed protection effect on the battery body, making the battery body safer and more stable.
