Abstract
Description
Technical Field
[0001] The utility model relates to a battery easy-to-tear insulating protective film with a bottom trimmed and extended insulating structure. Background Art
[0002] With the advancement of technology, the trend of ultra-thin mobile phones requires that the thickness of batteries must also be ultra-thin. However, when repairing or replacing the battery of a mobile phone, the battery needs to be disassembled, and ultra-thin batteries increase the difficulty and cost of disassembly. Therefore, the surface of the current battery is affixed with an easy-to-tear insulating aluminum-plastic protective film to facilitate the later maintenance personnel to disassemble the battery.
[0003] However, when applying the easy-to-tear sticker to the battery, the insulation of the bottom cut edge of the aluminum-plastic film at the folded edge of the battery cell must be solved. In the past, the design of folding the long ears of the easy-to-tear sticker back or folding the aluminum-plastic film at a small angle at the folded edge of the battery cell was generally adopted. However, such solutions have high requirements for the positioning of the easy-to-tear sticker, which will increase the difficulty and cost of manual pasting during processing, and will also increase the difficulty of folding the aluminum-plastic film at a small angle at the battery cell, and there is a risk of insulation failure due to inadequate folding. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a battery easy-to-tear insulating protective film with a bottom trimmed and extended insulating structure which has a simple structure, is easy to install and can avoid insulation failure.
[0005] The utility model comprises a main protective surface, a top protective surface, a side folded edge pasted protective surface, a bottom folded edge pasted protective surface and a protruding tearable sheet, wherein the top protective surface is adaptively connected and placed on the top of the main protective surface, the two side folded edge pasted protective surfaces are adaptively connected and placed on both sides of the main protective surface, the protruding tearable sheet is adaptively connected and placed on the edge of one side folded edge pasted protective surface, the bottom folded edge pasted protective surface is adaptively connected and placed on the bottom of the main protective surface, and the two sides of the bottom folded edge pasted protective surface are adaptively extended and provided with extended protrusions, and the distance between the two extended protrusions is greater than the width of the main protective surface.
[0006] The bottom folded edge pasting protective surface is adapted to be provided with a battery body bottom covering supporting portion, and the two side folded edge pasting protective surfaces are respectively adapted to be provided with battery body side covering supporting portions, and the width of the battery body bottom covering supporting portion corresponds to the width of the battery body side covering supporting portion.
[0007] The two extended protrusions are adapted to be placed under the two corresponding side folded edge adhesive protection surfaces.
[0008] Beneficial effect: In the utility model, the two sides of the bottom folded edge pasted protective surface are respectively adapted to be extended with extended protrusions, which improves the insulation of the battery aluminum-plastic film base glue after covering the battery body, and at the same time increases the insulation area, thereby reducing the difficulty of insulation processing, improving product quality, and avoiding the hidden danger of battery failure due to long-term use.

[0013] like Figure 1 , Figure 2 In the past, the bottom cutting edge of the battery aluminum-plastic insulation easy-to-tear protective film did not have an extended insulating part.
[0014] like Figure 3 As shown, the utility model includes a main protective surface 1, a top protective surface 2, a side folded edge pasted protective surface 3, a bottom folded edge pasted protective surface 4 and a protruding tearable sheet 5. The top protective surface 2 is adaptably connected and placed on the top of the main protective surface 1, and the two side folded edge pasted protective surfaces 3 are respectively adaptably connected and placed on both sides of the main protective surface 1. The protruding tearable sheet 5 is adaptably connected and placed on the edge of one side folded edge pasted protective surface 3, and the bottom folded edge pasted protective surface 4 is adaptably connected and placed at the bottom of the main protective surface 1. Both sides of the bottom folded edge pasted protective surface 4 are respectively adaptably extended and provided with extended protrusions 41, and the distance between the two extended protrusions 41 is greater than the width of the main protective surface 1.
[0015] The bottom folded edge pasting protection surface 4 is adapted to be provided with a battery body bottom covering support portion 42, and the two side folded edge pasting protection surfaces 3 are respectively adapted to be provided with battery body side covering support portions 31, and the width of the battery body bottom covering support portion 42 corresponds to the width of the battery body side covering support portion 31. The two extended protrusions 41 are adapted to be placed under the two corresponding side folded edge pasting protection surfaces 3.
[0016] like Figure 4As shown, the utility model is bonded to the external battery 6 by placing the front side of the external battery body 6 on the main protective surface 1, and then the side folded edge pasted protective surface 3 and the bottom folded edge pasted protective surface 4 are folded along the two side ends and the bottom of the external battery body 6 and then pasted on the back side of the external battery body 6, and the protruding tear sheet 5 is also pasted on the back side of the external battery body 6 in the same direction, and the two side ends of the external battery body 6 are respectively pasted on the side covering support part 31 of the battery body, and the bottom of the external battery body 6 is pasted on the bottom covering support part 42 of the battery body.
[0017] Since the extended protrusions 41 are placed on both sides of the bottom of the external battery body 6 after being attached to the external battery body 6, the insulating area of the bottom of the external battery body 6 is increased, thereby avoiding the hidden danger of battery failure caused by long-term use of the external battery body 6 in the future.
[0018] The utility model is suitable for the field of ultra-thin battery aluminum-plastic film insulation easy-to-tear stickers.
