Referring to fig. 1-3, a method for manufacturing an electronic device 100 according to an embodiment of the invention includes the following steps:
s1, providing an inner shell 10, wherein the inner shell 10 is formed with a battery compartment 101, and the battery compartment 101 comprises a bottom surface 102 and a side wall 103;
s2, providing a battery 20 (see fig. 4), the battery 20 including a lower surface 202 opposite to the bottom surface 102 and a side surface 204 corresponding to the side wall 103;
s3, providing the first adhesive 30, and adhering the first adhesive 30 to the bottom surface 102;
s4, providing an adhesive film 60, bonding the adhesive film 60 to the bottom surface 102, the side wall 103 and the first adhesive 30 to fix the adhesive film 60 in the battery compartment 101 and on the first adhesive 30, and bonding the lower surface 202 to the adhesive film 60 to pre-fix the battery 20 on the adhesive film 60; and
s5, providing the second adhesive 40 (see fig. 6 and 7), and coating the second adhesive 40 between the adhesive film 60 and the side surface 204 corresponding to the side wall 103 to fix the battery 20 on the adhesive film 60, wherein the adhesive force between the adhesive film 60 and the second adhesive 40 is smaller than the tensile force of the surface of the battery 20.
Referring to fig. 2-5, an electronic device 100 according to an embodiment of the invention includes an inner case 10, a battery 20, a first adhesive 30, an adhesive film 60, and a second adhesive 40. The inner case 10 is formed with a battery compartment 101, and the battery compartment 101 includes a bottom surface 102 and a side wall 103. The battery 20 includes a lower surface 202 opposite the bottom surface 102 and side surfaces 204 corresponding to the side walls 103. The first adhesive 30 is adhered to the bottom surface 102. The adhesive film 60 is bonded to the bottom surface 102, the side wall 103 and the first adhesive 30 to fix the adhesive film 60 in the battery compartment 101 and on the first adhesive 30, and the lower surface 202 is bonded to the adhesive film 60 to pre-fix the battery 20 on the adhesive film 60. The second adhesive 40 is coated between the adhesive film 60 and the side surface 204 corresponding to the side wall 103 to fix the battery 20 on the adhesive film 60, and the adhesive force between the adhesive film 60 and the second adhesive 40 is smaller than the tensile resistance of the surface of the battery 20.
According to the manufacturing method and the electronic device 100 of the embodiment of the invention, the adhesive film 60, the first adhesive 30 and the second adhesive 40 are used together to fix the battery 20 in the battery compartment 101, and since the adhesive force of the adhesive film 60 and the second adhesive 40 is smaller than the tensile force of the surface of the battery, the phenomenon that the battery 20 is scrapped due to bending, damage and the like of the battery 20 caused by too large adhesive force of the adhesive film 60 or the second adhesive 40 adhering to the battery 20 when the battery 20 is disassembled can be avoided. Meanwhile, the adhesive film 60 is arranged between the battery 20 and the battery compartment 101, after the battery 20 is disassembled, the second adhesive 40 adhered to the adhesive film 60 can be cleaned out of the battery compartment 101 only by tearing the adhesive film 60 out of the battery compartment 101, so that the second adhesive 40 adhered to the battery compartment 101 can be cleaned conveniently, and the situation that the second adhesive 40 flows into the bottom surface 102 along the side wall 103 to cause the adhesive 40 adhered to the bottom surface 102 to be difficult to clean is avoided.
Specifically, the sidewall 103 of the battery compartment 101 is connected to the bottom surface 102 and the sidewall 103 surrounds the bottom surface 102 to form the battery compartment 101. Side 204 of cell 20 is connected to lower surface 202 and side 204 surrounds lower surface 202. The glue film 60 is located between the battery compartment 101 and the battery 20, the first glue 30 is located between the battery compartment 101 and the glue film 60, and the second glue 40 is located between the glue film 60 and the battery 20, that is, the battery compartment 101, the first glue 30, the glue film 60, and the second glue 40 are sequentially disposed. The adhesive film 60 is fixed in the battery compartment 101 by the first adhesive 30, and the battery 20 is fixed on the adhesive film 60 by the adhesive film 60 and the second adhesive 40, such that the lower surface 202 is opposite to the bottom surface 102 and the side surface 204 is opposite to the side wall 103. When the battery 20 is pre-fixed in the battery compartment 101, the adhesive force of the adhesive film 60 only needs to ensure that the installation position of the battery 20 does not move in the manufacturing process, and the battery 20 does not need to be completely fixed through the adhesive film 60.
In some embodiments, the "adhesive force of the adhesive film 60 and the second adhesive 40 is less than the tensile force of the surface of the battery" may be understood as: the adhesive force of the adhesive film 60 is smaller than the tensile resistance of the adhesive film 60 adhered to the surface of the battery at the corresponding position of the battery 20; the adhesion of the second adhesive 40 is less than the tensile resistance of the second adhesive 40 to the surface of the battery at the corresponding location on the battery 20.
Experiments prove that: if the battery 20 is a lithium battery and the surface of the battery cell of the battery 20 is packaged by an aluminum-plastic film, the battery 20 can be completely fixed on the adhesive film 60 under the combined action of the adhesive force of the adhesive film 60 and the second adhesive 40.
Referring to fig. 6 and 7, an electronic device 100 according to an embodiment of the invention includes an inner case 10, a battery 20, a first adhesive 30, an adhesive film 60, and a second adhesive 40. The electronic device 100 includes, but is not limited to, a cell phone, a tablet computer, a smart watch, and the like. The present embodiment is described by taking the electronic device 100 as a mobile phone as an example.
Referring to fig. 2, the inner casing 10 is in a rectangular frame shape, the inner casing 10 includes a front surface 104 and a rear surface 105 opposite to the front surface 104, and the inner casing 10 further includes an upper end 106 and a lower end 107 opposite to the upper end 106.
By arranging the battery 20 at one end of the inner casing 10, the heat generated by the battery 20 can be easily dissipated to the outside of the inner casing 10, and the problem that the temperature of the whole electronic device 100 is too high due to the fact that the battery 20 is not easily dissipated when being located at the middle position of the inner casing 10 is avoided.
The inner shell 10 may be made of plastic.
Referring to fig. 4, the battery 20 is in a rectangular block shape, and the battery 20 includes a body 22 and a handle 24.
Body 22 includes lower surface 202, side 204, upper surface 206 and battery cover 208, and side 204 is connected with lower surface 202, upper surface 206 and side 204 encircles lower surface 202 and upper surface 206, and lower surface 202 is the back of upper surface 206, and battery cover 208 is located side 204 of body 22.
The hand pull strap 24 is in the form of a rectangular bar, and the hand pull strap 24 includes a fixed end fixed to the lower surface 202 and the side surface 204 and a free end extending out of the gap between the side wall 103 and the side surface 104. When it is desired to remove the battery 20, the user can remove the battery 20 from the battery compartment 101 by pulling on the free end. Or hand brace 24 is fixedly disposed on lower surface 202, side 204 and upper surface 206.
Specifically, the hand-pulling strip 24 is completely attached to the surface of the body 22, and when the battery 20 needs to be detached, the user can lift the battery 20 from the position where the hand-pulling strip 24 is attached, so as to detach the battery 20 from the battery compartment 101; of course, other means may be used by the user to pull the battery 20 from the location where the hand pull strap 24 is attached.
The battery 20 may be a lithium battery, the surface of the core of the battery 20 is packaged by an aluminum plastic film, and the material of the battery cover 208 includes plastic. The tensile resistance of the cell surface of the lower surface 202 and the upper surface 206 of the cell 20 is less than or equal to 1N/cm2The surface tensile resistance of the side surface 204 is less than 10N/cm2. The hand pull strap 24 may include a high temperature resistant polyester film (PET film).
Referring to fig. 2, 6 and 7, the first adhesive 30 is disposed on the bottom surface 102 of the battery compartment 101. The first adhesive 30 is used to adhere and fix to the bottom surface 102 of the battery compartment 101. Specifically, the first adhesive 30 is only adhered to a portion of the bottom surface 102 (i.e., the first adhesive does not completely cover the bottom surface 102), and the first adhesive 30 is a double-sided adhesive.
Referring to fig. 3 and 7, the adhesive film 60 is adhered to the bottom surface 102, the sidewall 103 and the first adhesive 30. Specifically, at a position where the first adhesive 30 is disposed in the battery compartment 101, the adhesive film 60 is located between the first adhesive 30 and the battery 20; in the position where the first adhesive 30 is not present in the battery compartment 101, the adhesive film 60 is located between the battery compartment 101 and the battery 20. The adhesive film 60 has a certain adhesive force, and the adhesive film 60 can be fixed in the battery compartment 101 under the combined action of the adhesive force of the adhesive film 60 adhering to the bottom surface 102 and the side wall 103 and the adhesive force of the first adhesive 30 adhering to the adhesive film 60; the lower surface 202 of the battery 20 is adhered to the adhesive film 60, and the adhesive film 60 is used to pre-fix the battery 20 on the adhesive film 60. The adhesive force of the adhesive film 60 adhering to the lower surface 202 is smaller than the tensile force of the battery surface and larger than the force of pre-fixing the battery 20 to the adhesive film 60. Specifically, the cell surface is the lower surface 202 of the cell 20, and the tensile strength of the cell surface is less than 1N/cm2. The adhesive film 60 may be a polyethylene terephthalate (PET) adhesive film.
Referring to fig. 6 and 7, the second adhesive 40 is coated in the gap between the adhesive film 60 corresponding to the sidewall 103 of the battery compartment 101 and the side 204 of the battery 20 to fix the battery 20 on the adhesive film 60. The adhesion force of the second adhesive 40 to the side 204 is less than the tensile force of the cell surface and the adhesion force to the first adhesive 30 is greater than the adhesion force required to fix the cell 20. Specifically, the cell surface is the side 204 of the cell 20, and the tensile strength of the cell surface is less than 10N/cm2. The second adhesive 40 can be silicone adhesive, and this adhesive can be usedThe second adhesive 40 can be disposed in the gap by dispensing.
According to the manufacturing method of the electronic device 100 and the electronic device 100, the first adhesive 30 and the second adhesive 40 fix the battery 20 in the battery compartment 101, and the adhesion force of the first adhesive 30 and the second adhesive 40 is smaller than the tensile force of the surface of the battery, so that the phenomenon that the battery 20 is scrapped due to bending, damage and the like of the battery 20 caused by too large adhesion force of the adhesive adhering to the battery 20 when the battery 20 is disassembled can be avoided. Meanwhile, the adhesive film 60 is arranged between the battery 20 and the battery compartment 101, after the battery 20 is disassembled, the second adhesive 40 adhered to the adhesive film 60 can be cleaned out of the battery compartment 101 only by tearing the adhesive film 60 out of the battery compartment 101, so that the second adhesive 40 adhered to the battery compartment 101 can be cleaned conveniently, and the situation that the second adhesive 40 flows into the bottom surface 102 along the side wall 103 to cause the adhesive 40 adhered to the bottom surface 102 to be difficult to clean is avoided.
In addition, the electronic device 100 of the embodiment of the invention has the following beneficial effects: first, since the inner case 10 and the battery compartment 101 have regular shapes, the inner case 10 and the battery compartment 101 according to the embodiment of the present invention are easier to mold and manufacture than the inner case and the battery compartment having irregular shapes. Moreover, the use of plastic for the inner shell 10 makes the inner shell 10 easier to manufacture and mold than if the inner shell 10 were made of metal, which is lighter in weight and less costly than an inner shell made of metal.
Next, in the battery 20, the battery cover 208 is provided on the side surface 204, so that it is possible to prevent the gap between the side surface 204 and the side wall 103 from being reduced due to the expansion of the battery 20 from the center position toward the side wall 204, and it is possible to prevent the increase of the adhesive force between the side surface 204 and the side wall 103, which makes it difficult to detach the battery 20. The batteries 20 are provided with a hand pull 24 to facilitate the user to remove the batteries 20 from the battery compartment 101 from the position of the pull strip 24 by hand pull 24 or by other means.
Moreover, because the adhesive film 60 has a small adhesive force for adhering the battery compartment 101, and the double-sided adhesive tape can firmly adhere the battery compartment 101 and the adhesive film 60, the adhesive film 60 can be firmly adhered in the battery compartment 101 through the double-sided adhesive tape, and the battery 20 fixed on the adhesive film 60 is prevented from moving along with the adhesive film 60. Meanwhile, the first adhesive 30 is bonded with the adhesive film 60 and the battery compartment 101 by using double-sided adhesive paper without curing. Therefore, the mounting process of the adhesive film 60 pre-fixed in the battery compartment 101 through the double-sided adhesive paper is simpler and more convenient.
Finally, since the silicone gel is like a paste and the cured silicone gel has vibration resistance. Therefore, the silicone adhesive can be conveniently dropped into the gap between the side surface 204 of the battery 20 and the adhesive film 60 corresponding to the side wall 103 by a dispensing method, and after the silicone adhesive is cured, the silicone adhesive can better fix the battery 20 on the adhesive film 60 even if the electronic device 100 vibrates.
Referring to fig. 2 and 4, in some embodiments, the shapes of the inner case 10, the battery compartment 101, and the battery 20 described in the above embodiments are not limited to those described in the above embodiments. The shapes of the inner shell 10, the battery compartment 101 and the battery 20 which meet the matching of the shape and the size of the battery 20 and the battery compartment 101 are all within the protection scope of the invention. That is, the shape of the battery 20 is similar to the shape of the battery compartment 101, and the dimensions of the lower surface 202 and the side surfaces 204 of the battery 20 are slightly smaller than the dimensions of the bottom surface 102 and the side walls 103 of the battery compartment 101 so that the battery 20 can be mounted within the battery compartment 101. Thus, the battery 20 can be installed in the battery compartment 101, and the structure of the electronic device 100 is more compact after the battery 20 is installed in the battery compartment 101.
In some embodiments, the material of the inner shell 10 described in the above embodiments is not limited to the plastic material described in the above embodiments, and the inner shell 10 may be made of metal (e.g., aluminum alloy, magnesium alloy), nonmetal or other special materials according to needs.
Referring to fig. 4, in some embodiments, the number of the pull strips 24 may be multiple, and the multiple pull strips 24 may be symmetrically disposed on the battery 20 or on the same side of the battery 20, so as to facilitate the removal of the battery 20 from the battery compartment 101 through the multiple pull strips 24. Of course, the battery 20 described in the above embodiment may not include the hand-pulling strip 24 or the battery cover 208, and as long as the adhesion force of the first adhesive 30 and the second adhesive 40 is less than the tensile force of the surface of the battery, the battery 20 can be detached from the battery compartment 101 without damaging the battery 20.
Referring to fig. 3, in some embodiments, the adhesive film 60 of the above embodiments is not limited to a PET adhesive film, and the adhesive film 60 may be other adhesive films with adhesive property, so long as the adhesive film can pre-fix the battery 20 on the adhesive film, which falls within the protection scope of the present invention.
Referring to fig. 2, in some embodiments, the first adhesive 30 of the above embodiments includes a plurality of double-sided adhesive paper sheets, and the double-sided adhesive paper sheets are spaced apart from each other and distributed on the bottom surface 102. By arranging a plurality of double-sided adhesive tapes, the bonding force of the battery 20 pre-fixed in the battery compartment 101 is large, and the situation that the manufacturing accuracy of the electronic device 100 is poor due to the movement of the battery 20 in the manufacturing process of the electronic device 100 is avoided. Of course, the first adhesive 30 is not limited to double-sided adhesive paper, and the first adhesive 30 may also be easy-to-pull adhesive, easy-to-detach adhesive, or the like.
In some embodiments, the second adhesive 40 described in the above embodiments is not limited to silicone adhesive, and other glues can be used for the second adhesive 40 as long as the glue can be dripped into the gap between the side surface 204 and the sidewall 103, and the adhesive force of the glue after curing is smaller than the tensile resistance of the surface of the battery.
Referring to fig. 8, in some embodiments, the battery 20 includes an upper surface 206 opposite a lower surface 202, and the manufacturing method further includes the steps of:
s6, coating the second adhesive 40 on the upper surface 206 or the peripheral edge of the upper surface 206;
s7, providing the rear cover 50, fastening the rear cover 50 to the inner case 10 to cover the battery 20 and press the second adhesive 40; and
and S8, curing the second adhesive 40.
That is, the manufacturing method may include steps S1 to S8.
Referring to fig. 6 and 7, specifically, if there is a gap between the lower surface 202 of the battery 20 and the bottom surface 102 of the battery compartment 101 (i.e., there is a gap between the adhesive film 60 corresponding to the bottom surface 102 and the lower surface 202), and the gap is larger than the increased volume of the battery 20 after swelling, the second adhesive 40 can be coated on the entire upper surface 206. If there is a gap between the lower surface 202 of the battery 20 and the bottom surface 102 of the battery compartment 101, but the gap is smaller than the increased volume of the battery 20 after swelling, or there is no gap between the lower surface 202 and the bottom surface 102, the second adhesive 40 is coated on the peripheral edge of the upper surface 206, so that there is a gap between the central position of the upper surface 206 of the battery 20 and the rear cover 50. When the battery 20 is deformed and expanded, the gap can accommodate the volume of the battery 20 increased due to the expansion, and further, the battery 20 is prevented from being extruded after being expanded to cause failure or even explosion. Before the second adhesive 40 is cured, when the rear cover 50 is fastened and fixed to the inner casing 10, the rear cover 50 presses against the second adhesive 40 to enable the second adhesive 40 to completely fill the gap between the side wall 103 and the side surface 204 (i.e. the gap between the adhesive film 60 corresponding to the side wall 103 and the side surface 204). After the second adhesive 40 is cured, the rear cover 50 is pressed against the second adhesive 40 to fix the battery 20 in the battery compartment 101, so as to better prevent the battery 20 from loosening.
