Description

Technical Field

[0001] The utility model relates to the technical field related to lithium battery shells, and in particular to a lithium battery shell structure with a locking hook. Background Art

[0002] Lithium-ion batteries are a key power source for electric vehicles and hybrid electric vehicles. Battery capacity and service life are two key factors restricting the development of electric vehicles. To ensure battery charge and discharge efficiency and service life, lithium-ion batteries must be well protected. Lithium-ion batteries require a housing to house them during use. However, the number of lithium batteries in a traditional lithium-ion battery housing is fixed, which is very wasteful for users who need a small amount of power. Lithium-ion batteries will discharge until they are completely empty when not in use. Moreover, some lithium-ion batteries need to be stored when not in use, but stacking them will not dissipate heat well.

It discloses a lithium battery with an easy-to-remove shell, including a device shell, a rotating rod movably connected to the inner side of the device shell, a movable stud fixedly connected to the rear side of the rotating rod, a movable groove opened on the inner side of the device shell, a movable block movably connected to the inner side of the movable groove, a movable plate fixedly connected to the upper side of the movable block, the movable block and the movable stud are threadedly connected, a belt movably connected to the outer side of the rotating rod, and a movable rod movably connected to the upper side of the belt. The utility model provides a movable stud so that the movable plate can be moved, thereby facilitating the separation of the lithium battery on the upper side of the movable plate from the device shell, thereby improving the convenience of device separation. By providing a first gear, the first gear can drive the first clamping plate and the second clamping plate to move and separate them from the lithium battery, further improving the convenience of disassembly of the device shell and solving the problem of the inconvenience of disassembling the existing lithium battery shell. The disadvantage of this utility model is that the number of lithium batteries cannot be increased or decreased as needed, and the lithium batteries cannot be suspended. Utility Model Content
