Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to an easily replaceable lithium battery. Background Art

[0002] Lithium-ion battery is a secondary battery rechargeable battery that mainly relies on the movement of lithium ions between the positive and negative electrodes to work.

[0003] When a lithium battery is in use, in order to increase its service life, a protective shell is set on the surface of the lithium battery. The protective shell protects the lithium battery inside and prevents external factors from affecting the normal use of the lithium battery. Although the use of the protective shell can effectively protect the lithium battery, when the lithium battery itself has a problem, it is not convenient to take it out for replacement because it is inside the protective shell. For this reason, we propose an easily replaceable lithium battery. Utility Model Content

[0004] 1. Technical issues to be resolved

[0008] Furthermore, side plates are movably provided on both sides of the bottom plate, and support plates are fixedly provided on the opposite sides of the two side plates, and the support plates support the bottom of the protective shell. The bottom of the support plates is hinged to the bottom plate, so that the side plates and the support plates can rotate on the bottom plate. When rotating to both sides, the support plates will be separated from the bottom of the protective shell, and the bottom of the protective shell will not be supported. Then the ejection assembly can eject the battery cell upward for a distance.

[0009] Furthermore, a spherical clamping block is provided on the side panel, and a spherical clamping groove is opened at the bottom of the side of the protective shell. The spherical clamping block is clamped with the inside of the spherical clamping groove. The spherical clamping block can be clamped inside the spherical clamping groove, so that the side panel can be fixed on the side of the protective shell.

[0010] Furthermore, an arc-shaped shifting block is fixedly provided on one side of the side plate away from the spherical clamping block, and the side plate and the support plate can be opened to both sides only by forcibly shifting the arc-shaped shifting block to both sides.

[0011] Furthermore, ventilation windows are provided on the front and rear sides of the protective shell, and a dustproof net is provided inside the ventilation window. Through the setting of the ventilation windows, the interior of the protective shell can be ventilated and heat can be dissipated, and then through the setting of the dustproof net, the entry of dust into the interior of the protective shell can be reduced.

[0012] Compared with the prior art, the present invention provides an easily replaceable lithium battery having the following features:

[0013] Beneficial effects:

[0014] When the battery cell of the easily replaceable lithium battery needs to be replaced, one only needs to open the top cover and then pull the arc-shaped pull blocks to both sides so that the side plates and the support plate rotate to both sides and the support plate separates from the bottom of the protective shell. Then the tension spring pulls the bottom plate upward to move the vertical plate and the top plate upward. The top of the top plate pushes the battery cell upward for a distance so that the top is exposed outward, and then the battery cell can be easily taken out from the inside of the protective shell for replacement.
