Description

Technical Field

[0001] The utility model relates to the field of electric bicycles, in particular to a lithium battery protection box. Background Art

[0002] Electric bicycles are common daily means of transportation, and lithium batteries are standard accessories for most electric bicycles. There are frequent reports of fires caused by lithium batteries. The reasons for lithium battery fires are mostly overcharging during charging, battery aging, and internal positive and negative short circuits caused by external impacts. During cycling, bumps are inevitable. If unfortunately, the battery is bumped or even impacted, it is very likely to cause internal deformation and short circuit, leading to a fire. Many lithium battery protection boxes are designed to be enclosed. Although this effectively protects against fires caused by bumps or impacts, it increases the difficulty of heat dissipation, with both advantages and disadvantages.

[0003] The above problems objectively exist in daily practice. Therefore, there is an urgent need for a supporting battery protection box to solve the above problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to scientifically design a lithium battery protection box. By innovatively designing a protection box with left and right side plates, it is convenient for inserting and removing the lithium battery. The open design facilitates the heat dissipation of the lithium battery. While providing protection, it also takes into account heat dissipation, which can prevent fires caused by bumps or impacts and avoid fires caused by overheating due to poor heat dissipation, achieving the beneficial effect of effectively reducing fires.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows: A lithium battery protection box is integrally set as a "C"-shaped protection box composed of a bottom plate on one side and side plates on the left and right sides respectively. A plurality of mounting holes are provided on the bottom plate on one side, and the left and right side plates are both set as panels that are narrow at the upper part and wide at the lower part, and are respectively combined with the bottom plate to form the "C"-shaped protection box that is shallow at the upper part and deep at the lower part.

[0006] A first through hole is provided at the upper part of the left side plate;

[0007] A second through hole is provided at the upper part of the right side plate.

[0008] The lithium battery is inserted into the "C"-shaped protection box from top to bottom and fixed.

[0009] The "C"-shaped protection box is fixedly arranged on the square tubes respectively arranged on both sides of the vertical rod of the handlebar of the electric bicycle through the plurality of mounting holes on the bottom plate, forming an installation and fixation.

[0010] Compared with the prior art, the advantages of the utility model are as follows:

[0011] The utility model relates to a lithium battery protection box. By innovatively designing a protection box with left and right protective plates, it is convenient for inserting and removing the lithium battery.
