Referring to fig. 1 and 2, a battery assembly 100 according to an embodiment of the present invention includes a battery 1 and a light guide film 2 disposed outside the battery 1, a UV adhesive layer 3 is disposed between the battery 1 and the light guide film 2, and the battery 1 and the light guide film 2 are adhered and fixed by the UV adhesive layer 3. The battery assembly 100 is fixed in the battery carrier case 200 by an adhesive.
The light guide film 2 is made of a flexible material, which is any one of PET, PC, and PMMA, but is not limited thereto. The light guide film 2 is provided with the microstructure 21 on the surface of one side far away from the battery 1, and the microstructure 21 is used for guiding the light which is totally reflected in the light guide film 2 and emitting the light from the surface of the light guide film 2, so that the surface of the light guide film 2 uniformly emits light, and the emitted light irradiates the UV adhesive layer 3.
The microstructures 21 are protrusions or grooves, that is, the microstructures 21 are formed by inward concave or outward convex on the surface of the side, away from the cell 1, of the light guide film 2, the width and the cross-sectional height of the protrusions or grooves are nanometer or micrometer in size, the specific size is not particularly limited, and the microstructures can be arranged according to actual needs. The cross-sectional shape of the microstructure 21 is any one of a triangle, a circle, a square, and an arc, but is not particularly limited thereto, and the cross-sectional shape of the microstructure 21 may be other shapes, which are not listed here. The shape of the microstructures 21 formed on the surface of the light guide film 2 is not limited herein, and may be a semicircular shape, a pyramidal shape, a rectangular shape, a long strip shape, or the like, which is not illustrated herein. The density of the microstructures 21 may be set according to actual needs, and is not particularly limited herein.
The light guide film 2 is provided with a reflecting layer (not shown) at one side far away from the battery 1, the reflecting layer is used for reflecting light, the light reflected by the reflecting layer irradiates the light guide film 2, the light energy is fully utilized, and meanwhile, the uniformity of the light guide film 2 can be improved. The material of the reflecting layer is one or more of reflecting ink, metallic silver and metallic aluminum. The reflective layer is formed by coating or plating a reflective material on the light guide film 2.
When the battery needs to be disassembled, UV light irradiates the end face of the light guide film 2 to enter the light guide film body as shown in fig. 3, and the UV light irradiates the UV adhesive layer 3 through the light guide film 2 to enable the UV adhesive layer 3 to be solidified and lose viscosity, so that the battery 1 is separated from the light guide film 2. Specifically, after UV light shines leaded light membrane 2, light can take place the total reflection in leaded light membrane 2, light can't jet out, need increase some optical micro structure 21 in the bottom of leaded light membrane 2 in order to destroy the light propagation direction in leaded light membrane 2, through the effect of micro structure 21 and reflection stratum, UV light jets out by the surface of leaded light membrane 2 and shines UV glue film 3, and then lead to UV to glue the solidification and lose viscidity, under the exogenic action, the UV glue film 3 that breaks away from that battery 1 can relax, namely, break away from leaded light membrane 2 surface, battery 1 has been realized the not damaged and has been dismantled.
The battery assembly 100 is fixed in the battery carrying case 200 by an adhesive, specifically, the adhesive is disposed between the battery carrying case 200 and the reflective layer of the light guide film 2. Bond through UV glue film 3 between battery 1 and the leaded light membrane 2, leaded light membrane 2 bonds through the gluing agent and fixes to battery bears casing 200 on, through applying external force, can firmly fix battery 1, leaded light membrane 2 in battery bears shell 200, satisfies practical application. The adhesive may be a double-sided adhesive tape or other materials for bonding, which are not listed here.
The battery carrying case 200 has a groove shape, the battery assembly 100 is embedded in the battery carrying case 200, and the battery 1 includes a bottom surface and four side surfaces close to the battery carrying case 200, and a surface far from the battery carrying case 200. Wherein the surface of the battery 1 is exposed when the battery assembly 100 is positioned in the battery carrying case 200.
In the embodiment, please refer to fig. 1, the light guiding film 2 encloses the bottom surface and at least one side surface of the battery 1, and the two side surfaces are oppositely disposed, so that when the battery 1 and the light guiding film 2 are fixed in the battery carrying case 200, the end surface of the light guiding film 2 is exposed to the outside, thereby facilitating the irradiation of UV light.

When carrying out unilateral UV light irradiation to above-mentioned leaded light membrane, the light density distribution that leaded light membrane is close to one side of UV light source is great, and along with the distance increase apart from the UV light source, the light density distribution on the leaded light membrane reduces gradually, for making the even light-emitting in leaded light membrane surface, the distribution density of micro-structure on the leaded light membrane increases along with the distance increase apart from UV light. When carrying out two side UV light irradiations to above-mentioned leaded light membrane, the leaded light membrane is close to the light density distribution of the both sides of UV light source great, therefore the micro-structure density distribution on the leaded light membrane is less, and the intermediate position of leaded light membrane, light density distribution is less, and then the density distribution of micro-structure on the leaded light membrane is great to make the even light-emitting in leaded light membrane surface.
Referring to fig. 5 and 6, in the effect graphs of the single-sided UV light irradiation and the double-sided UV light irradiation, it can be obtained that the optical uniformity of both irradiation modes is 80% -90%. However, the effect of the double-sided UV light irradiation is shorter in the action time of the UV paste and more excellent.
When shining the side that the leaded light membrane exposes outside through UV light, from the light directive UV glue film of leaded light membrane surface ejection, the solidification of UV glue loses viscidity, and under the exogenic action, the battery can easily be dismantled from the battery bears the shell, obtains whole undamaged battery.
The invention also provides electronic equipment, wherein the electronic equipment comprises the battery component, and the electronic equipment can be a mobile phone, a tablet, a computer and the like.
