Description
[ field of technology ]
The embodiment of the application relates to the technical field of electronic equipment, in particular to an electric device.
[ background Art ]
A battery is a device that converts external energy into electric energy and stores the electric energy therein to supply power to an electric device (e.g., a portable electronic device) at a desired time. At present, batteries are widely applied to power utilization devices such as mobile phones, tablets, notebook computers and the like, so that the power utilization devices have the characteristic of movable work. Generally, these power devices include a base and a battery; wherein, the base is equipped with the mounting groove with battery looks adaptation, and the battery is then installed in this mounting groove.
In some electric devices, the battery is fixed to the mounting groove by a double sided adhesive tape; because the adhesive force of the double faced adhesive tape is strong, users or maintenance personnel are difficult to detach the battery, and the battery can be taken out only by applying a large acting force, but the process has the hidden trouble of damaging the battery or the base of the power utilization device.
[ application ]
The embodiment of the application aims to provide an electric device so as to improve the current situation that a large force is applied to detach a battery from a base.
In order to solve the technical problems, the embodiment of the application adopts the following technical scheme:
an electrical device includes a base, a battery, an adhesive, an electrically releasable bond, a first adhesive layer, and a first substrate layer. The base has a mounting wall, and the electrically-peelable glue layer is disposed between the battery and the mounting wall to fix the battery to the mounting wall. A first conductive material layer is adhered to one side of the electric stripping adhesive layer facing the battery, a second conductive material layer is adhered to one side of the electric stripping adhesive layer facing the mounting wall, the electric stripping adhesive layer reduces viscosity or loses viscosity when a potential difference exists between the first conductive material layer and the second conductive material layer, and the first conductive material layer comprises at least one of silver, aluminum, copper and steel. The electric stripping adhesive layer comprises a base material and an adhesive arranged on two sides of the base material, wherein the adhesive is mixed with electrolyte, and the base material comprises a non-woven fabric with micropores or a polymer film with micropores. The first adhesive layer is arranged between the first conductive material layer and the battery so as to fix the first conductive material layer and the battery, and the first adhesive layer is arranged as an ultraviolet anti-adhesive layer. The first substrate layer comprises a polymer, the first substrate layer is arranged on one side of the electric stripping adhesive layer facing the battery, the first conductive material layer is coated on one side of the first substrate layer facing the electric stripping adhesive layer, and the material of the first substrate layer comprises: at least one of polyethylene terephthalate, polyurethane and polyimide. The first adhesive layer is arranged between the first substrate layer and the battery so as to enable the first substrate layer to be adhered and fixed with the battery. And the first adhesive layer, the first base material layer, the first conductive material layer, the electric stripping adhesive layer and the second conductive material layer are sequentially laminated along the thickness direction of the electric device. In this way, the thickness of the first conductive material layer can be controlled at a micrometer level or even a nanometer level, thereby being beneficial to reducing the overall material cost of the electric device.
Compared with the current electric device on the market, when the battery in the electric device provided by the embodiment of the application is dismounted, a user or a maintainer can apply voltage between the two conductive material layers so as to reduce the viscosity of the electric stripping adhesive layer, so that the user or the maintainer can detach the battery from the base through smaller pulling force, and the dismounting process is convenient and labor-saving. That is, the power utilization device provided by the embodiment of the application can improve the current situation that the battery can be detached from the base only by applying a large force, and further can reduce or eliminate the hidden trouble that the battery or the base is possibly damaged in the process of detaching the battery.
As a further development of the above-mentioned technical solution, the first substrate layer comprises a polymeric material. The first conductive material layer is coated on the first substrate layer by at least one of electroplating, spraying, printing and coating processes. Since the polymer is easier to realize small size in thickness than the metal, and the thickness of the first conductive material layer is very small, the embodiment is also beneficial to reducing the thickness of the whole material of the electric device.
As a further improvement of the above technical solution, the first conductive material layer is integrally formed with the battery; alternatively, the first conductive material layer is coated on the side of the battery facing the electrically-peelable glue layer.
As a further improvement of the above technical solution, the electric device further includes a second adhesive layer. The second adhesive layer is arranged between the second conductive material layer and the mounting wall so as to fix the second conductive material layer and the mounting wall.
As a further improvement of the above technical solution, the electric device further includes a second substrate layer. The second substrate layer is arranged on one side of the electric stripping adhesive layer facing the mounting wall, and the second conductive material layer is coated on one side of the second substrate layer facing the electric stripping adhesive layer. The second adhesive layer is arranged between the second substrate layer and the mounting wall so as to enable the second substrate layer to be adhered and fixed with the mounting wall. In this way, the thickness of the second conductive material layer can be controlled to be in the micrometer level or even in the nanometer level, thereby being beneficial to reducing the overall material cost of the power utilization device.
As a further improvement of the above technical solution, the second adhesive layer includes uv light or alcohol glue reducing. The ultraviolet light viscosity-reducing adhesive has better viscosity at normal temperature, so that the battery can be adhered; when the battery needs to be disassembled, the first adhesive layer can be cured into an integral adhesive layer by irradiating the first adhesive layer with ultraviolet light and the viscosity is reduced, so that a user or a maintenance personnel can easily remove the first adhesive layer from the surface of the battery. Similarly, the alcohol-based adhesive has better viscosity at normal temperature so as to adhere to the battery, and when the battery needs to be disassembled, the alcohol is dripped into the alcohol-based adhesive to reduce the viscosity of the alcohol-based adhesive, so that a user or a worker can easily remove the first adhesive layer from the surface of the battery.
As a further improvement of the above technical solution, the second conductive material layer is integrally formed with the mounting wall; alternatively, the second conductive material layer is coated on a side of the mounting wall facing the electric peeling glue layer.
As a further improvement of the above technical solution, the second conductive material layer includes at least one of aluminum, copper, steel, and graphene.
As a further improvement of the above technical solution, the edge of the first conductive material layer is provided with a first connection portion, and the first connection portion exceeds the edge of the electrical peeling glue layer. In this way, at least part of the first conductive material layer is exposed relative to the electrical stripping adhesive layer and/or the first adhesive layer, so that a user or a maintenance person can conveniently realize electrical connection between the wire and the first connection part. The edge of the second conductive material layer is provided with a second connecting part, and the second connecting part exceeds the edge of the electric stripping adhesive layer. Therefore, at least part of the second conductive material layer is exposed relative to the electric stripping adhesive layer and/or the second adhesive layer, and a user or a maintenance person can conveniently realize electric connection between the wire and the second connecting part.
As a further improvement of the above technical solution, the power utilization device further includes a circuit board. The first connecting portion and the second connecting portion are electrically connected with the circuit board.

Referring to fig. 1 and fig. 2 together, an exploded view of an electrical device 1 and a sectional view of the electrical device 1 along line A-A according to an embodiment of the application are shown, wherein the electrical device 1 includes a base 100, a battery 200, and an adhesive electrical peelable adhesive layer 300. The base 100 has a mounting wall 110; the electro-peelable adhesive layer 300 is disposed between the battery 200 and the mounting wall 110 to fix the battery 200 to the mounting wall 110. The first conductive material layer 400 is adhered to the side of the electro-peeling adhesive layer 300 facing the battery 200, and the second conductive material layer 500 is adhered to the side of the electro-peeling adhesive layer 300 facing the mounting wall 110, and the electro-peeling adhesive layer 300 reduces or loses adhesion when a potential difference exists between the first conductive material layer 400 and the second conductive material layer 500. Next, taking the electric device 1 as an intelligent terminal with an embedded system as an example, a specific structure of the electric device 1 will be described; it should be understood that in other embodiments of the present application, the power device may be any device having a battery and electrically driven, such as a sweeping robot, a fan, a shaver, etc.
For the base 100 and the battery 200, referring to fig. 1 specifically, the base 100 is a main body of the electric device 1, and has a mounting wall 110, and the battery 200 is mounted through the mounting wall 110. In this embodiment, the base 100 is provided with a mounting groove 101, and the cross section of the mounting groove 101 is rectangular, so that the inner wall surface thereof includes a bottom wall 111 and four side walls 112 connected in sequence. The battery 200 is accommodated in the mounting groove 101 and is mounted on the bottom wall 111 of the mounting groove 101 and on the opposite side walls 112 of the mounting groove 101. That is, the installation wall 110 in the present embodiment is generally U-shaped, and specifically includes the bottom wall 111 and two side walls 112. It is to be understood that even though the mounting wall 110 is provided as described above in the present embodiment, the specific shape of the mounting wall 110 is various, and the present application is not limited thereto. For example, in other embodiments of the application, the mounting wall 110 does not include the bottom wall 111 described above, but rather includes at least one side wall 112; for another example, in other embodiments of the present application, the mounting wall 110 includes both the bottom wall 111 and the side walls 112; for example, in still other embodiments of the present application, the battery 200 is not accommodated in the mounting groove 101, but is mounted on the outer wall surface of the base 100, that is, the outer wall surface of the mounting wall 110 serving as a base, through the electro-peeling adhesive layer 300; the specific arrangement of the mounting walls 110 is not described in detail herein.
Referring to fig. 3, a schematic structural diagram of the electrical device 1 in which the base 100 and the battery 200 are hidden after being unfolded into a flat state is shown, and referring to fig. 1 and 2, the electrical peelable adhesive layer 300 is formed into a sheet shape and bent into a U shape to be matched with the mounting wall 110. The electro-peelable adhesive layer 300 is provided between the battery 200 and the mounting wall 110 in the thickness direction thereof, with one side thereof facing the mounting wall 110 and the other side facing the battery 200. The electro-peelable adhesive layer 300 is an adhesive layer having a reduced or complete loss of adhesion when both sides thereof have conductive elements and the conductive elements have a potential difference; in this embodiment, the first conductive material layer 400 and the second conductive material layer 500 are disposed on two sides of the electrical peeling glue layer 300 respectively to achieve the above purpose. In this way, when no potential difference is applied between the first conductive material layer 400 and the second conductive material layer 500, the electro-peelable adhesive layer has good adhesiveness, thereby ensuring a stable fixing effect between the battery 200 and the mounting wall 110; when a potential difference is applied between the first conductive material layer 400 and the second conductive material layer 500, the viscosity of the electro-peelable adhesive layer 300 is reduced or completely lost, thereby reducing the fixing strength between the battery 200 and the mounting wall 110, and facilitating the removal of the battery 200 from the base 100 by a user or a serviceman. In this embodiment, the electro-release adhesive layer 300 includes a base material and an adhesive provided on both sides of the base material, wherein the adhesive is mixed with an electrolyte. Optionally, the substrate comprises a nonwoven fabric having micropores; the adhesive comprises an acrylic polymer; the electrolyte comprises an ammonium salt solution. When a voltage is applied to the first conductive material layer 400 and the second conductive material layer 500 on opposite sides of the electro-peelable adhesive layer 300 by using a power source, anions in the electrolyte move to the surface of the electro-peelable adhesive layer 300 toward one side of the positive electrode, and cations in the electrolyte move to the surface of the electro-peelable adhesive layer 300 toward one side of the negative electrode; as such, the microstructure of the electro-release glue layer 300 is destroyed, and its tackiness gradually decreases with the time of applying the potential difference, even completely loses tackiness. Therefore, when a user or a serviceman needs to detach the battery 200 from the base 100, the user or serviceman can easily detach the battery 200 from the base 100 by applying the potential difference between the first conductive material layer 400 and the second conductive material layer 500 for a predetermined period of time. It will be appreciated that the construction of the electro-peelable adhesive layer 300 is very diverse, so long as it is ensured that the adhesion force between the first conductive material layer 400 and the second conductive material layer 500 on both sides thereof after having a potential difference is reduced or completely lost, and the specific construction thereof is not limited by the present application. For example, in other embodiments of the present application, the substrate of the electro-release adhesive layer 300 may be other polymer films having micro holes, as long as it can pass ions, such as polyethylene terephthalate film; the adhesive may also comprise other polymer glues than acrylic, or a mixture of glues; the electrolyte may also include other electrolytes such as potassium salt solution, calcium salt solution, sodium salt solution, etc.
Next, the arrangement of the first conductive material layer 400 and the second conductive material layer 500, and the connection relationship between the two and the battery 200 and the mounting wall 110 will be described. In this embodiment, the power utilization device 1 includes a first conductive material layer 400 and a second conductive material layer 500 that are disposed separately from the battery 200 and the base 100, and further includes a first adhesive layer 410 for fixing the first conductive material layer 400 to the battery 200, and a second adhesive layer 510 for fixing the second conductive material layer 500 to the mounting wall 110. For ease of understanding, the first conductive material layer 400, the first adhesive layer 410, the second conductive material layer 500, and the second adhesive layer 510 are described in this order.
For the first conductive material layer 400, please further refer to fig. 1 to 3, the first conductive material layer 400 is made of a conductive material, and the whole of the first conductive material layer is also in a sheet shape and is bent into a U shape adapted to the electro-peelable adhesive layer 300. The first conductive material layer 400 is adhered to the side of the electro-peelable adhesive layer 300 facing the battery 200 in the thickness direction of the electro-peelable adhesive layer 300. Alternatively, the first conductive material layer 400 comprises aluminum, in particular an aluminum foil made of aluminum. It will be appreciated that in other embodiments of the present application, the first conductive material layer 400 may also include other conductive materials; examples of metals include copper, steel, gold, and silver, examples of non-metals include graphite and graphene, and examples of mixtures of at least two of the foregoing materials.
For the first adhesive layer 410, please further combine fig. 1 to 3, the first adhesive layer 410 has a U-shape adapted to the first conductive material layer 400. The first adhesive layer 410 has an adhesive property, and is disposed between the first conductive material layer 400 and the battery 200 to fix the first conductive material layer 400 to the battery 200. It should be noted that the material of the first adhesive layer 410 is various, and the present application is not limited thereto. For example, in some embodiments, the first adhesive layer 410 includes acrylic glue. For another example, in other embodiments, the first adhesive layer 410 includes an epoxy glue. Also for example, in still other embodiments, the first adhesive layer 410 includes an ultraviolet light reducing adhesive. The acrylic glue and the epoxy glue are easy to remain on the surface of the battery 200 in the process of disassembling the battery 200 due to strong viscosity; in contrast, the ultraviolet light viscosity-reducing adhesive has better viscosity at normal temperature, so that the battery 200 can be adhered; when it is desired to detach the battery 200, the first adhesive layer 410 may be cured into an integrated adhesive layer by irradiating the first adhesive layer 410 with ultraviolet light and the adhesive may be reduced so that a user or a serviceman can easily remove the first adhesive layer 410 from the surface of the battery 200. For another example, in still other embodiments of the present application, the first adhesive layer 410 includes an alcohol-reduced adhesive. The acrylic glue and the epoxy glue are easy to remain on the surface of the battery 200 in the process of disassembling the battery 200 due to strong viscosity; in contrast, the alcohol-based adhesive has better viscosity at normal temperature to adhere to the battery 200, and when the battery 200 needs to be disassembled, the alcohol-based adhesive is dripped into the alcohol-based adhesive to expand the alcohol-based adhesive to reduce the viscosity, so that the user or staff can easily remove the first adhesive layer 410 from the surface of the battery 200. In addition, it should be noted that, even though the first conductive material layer 400 is adhered to the battery 200 by the first adhesive layer 410 in the present embodiment, in other embodiments of the present application, the power utilization device 1 may not include the first adhesive layer 410, and accordingly, the first conductive material layer 400 may be fixed to the battery by other manners, such as welding, and the fixing manner of the first conductive material layer 400 and the battery 200 is not limited herein.
For the second conductive material layer 500, please further combine fig. 1 to 3, the second conductive material layer 500 is also made of a conductive material, and the whole of the second conductive material layer is also sheet-shaped and bent into a U-shape adapted to the electro-peelable adhesive layer 300. The second conductive material layer 500 is adhered to the side of the electro-release adhesive layer 300 facing the mounting wall 110. Optionally, the second conductive material layer 500 comprises aluminum, in particular an aluminum foil made of aluminum. It will be appreciated that in other embodiments of the present application, the second conductive material layer 500 may also include other conductive materials; examples of metals include copper, steel, gold, and silver, examples of non-metals include graphite and graphene, and examples of mixtures of at least two of the foregoing materials.
For the second adhesive layer 510, please further combine fig. 1 to 3, the second adhesive layer 510 has a U-shape adapted to the second conductive material layer 500. The second adhesive layer 510 has an adhesive property, and is disposed between the second conductive material layer 500 and the mounting wall 110 to fix the second conductive material layer 500 to the mounting wall 110. The material selection manner of the second adhesive layer 510 may specifically refer to the first adhesive layer 410, which is not described herein.
When a user or a serviceman needs to detach the battery 200, the user or the serviceman only needs to apply a potential difference to the first conductive material layer 400 and the second conductive material layer 500 and maintain the predetermined time period T, so that the adhesive force between the electro-peeling adhesive layer 300 and the first conductive material layer 400 (or the second conductive material layer 500) is reduced below the predetermined threshold value, and the user or the serviceman can easily remove the battery 200 from the base 100. It should be noted that, the "preset threshold" in the present document refers to a value of the force that the battery 200 can be easily and manually detached from the base 100 without using an external tool; for example, the preset threshold may be 0.2 kgf (kgf), or 0.1 kgf. The "preset duration" described in the present document is related to the potential difference between the two conductive material layers; for example, when the potential difference between the first conductive material layer 400 and the second conductive material layer 500 is 50V, the preset time period T is greater than or equal to 10S, the adhesive force between the electro-peelable adhesive layer 300 and the first conductive material layer 400 (or the second conductive material layer 500) is reduced to less than 0.1kgf, and when the potential difference between the two conductive material layers is 10V, the preset time period T is greater than or equal to 50S, the adhesive force between the electro-peelable adhesive layer 300 and the first conductive material layer 400 (or the second conductive material layer 500) is reduced to less than 0.1 kgf.
Further, in order to facilitate the user or the maintenance personnel to connect the first conductive material layer 400 when the battery 200 is disassembled, the edge of the first conductive material layer 400 is provided with a first connection portion 401, and the first connection portion 401 extends beyond the edge of the electro-peelable adhesive layer 300 and/or the edge of the first adhesive layer 410. In this way, the first conductive material layer 400 is at least partially exposed with respect to the electrically-peelable glue layer 300 and/or the first adhesive layer 410, and a user or a maintenance person can conveniently electrically connect the wires with the first connection portion 401. Similarly, to facilitate the user or maintenance personnel to connect the second conductive material layer 500 when the battery 200 is detached, the edge of the second conductive material layer 500 is provided with a second connection portion 501, and the second connection portion 501 extends beyond the edge of the electrical peeling glue layer 300 and/or the edge of the second adhesive layer 510. In this way, the second conductive material layer 500 is at least partially exposed with respect to the electrically-peelable glue layer 300 and/or the second adhesive layer 510, and a user or a maintenance person can conveniently electrically connect the wires with the second connection portion 501.
Next, a manner of applying a voltage to the first conductive material layer 400 and the second conductive material layer 500 in the present application will be described in detail.
In this embodiment, the power consumption device 1 further includes a circuit board 600, the circuit board 600 is electrically connected to the first connection portion 401 and the second connection portion 501, respectively, and the circuit board 600 is configured to apply a potential difference to the first connection portion 401 and the second connection portion 501 in due time according to a user operation, so that the viscosity between the electric peeling adhesive layer 300 and the first conductive material layer 400 and/or the viscosity between the electric peeling adhesive layer 300 and the second conductive material layer 500 are reduced below a predetermined threshold value, so that the user can easily remove the battery 200 from the base 100. Specifically, the circuit board 600 includes a switching circuit electrically connected to the battery 200 to provide an electric power source from the battery 200, and connected to the first connection portion 401 and the second connection portion 501, respectively. The switching circuit is configured to have an open state and a closed state; in the off state, there is no potential difference between the first conductive material layer 400 and the second conductive material layer 500; in the closed state, a potential difference exists between the first conductive material layer 400 and the second conductive material layer 500. The switching between the open state and the closed state can be realized through man-machine interaction, for example, a user or a maintenance personnel triggers a key or a display screen of the intelligent terminal, and the circuit board switches the state of the switch circuit according to the trigger signal; the switch circuit may be manually turned on or off by a user or a maintenance person, and the present application is not limited thereto. It should be noted that the circuit board may be a motherboard of the intelligent terminal or a battery protection board in the intelligent terminal. Of course, in other embodiments, the voltage may be applied to the first connection portion 401 and the second connection portion 501 by an external power source.
Compared with the current electric devices on the market, the electric device 1 provided by the embodiment of the application comprises a base 100, a battery 200 and an electric stripping adhesive layer 300. The first conductive material layer 400 and the second conductive material layer 500 are adhered to two sides of the electro-peeling adhesive layer 300 respectively. Therefore, when a user or a serviceman removes the battery 200 in the power consumption device 1 provided by the embodiment of the application, the voltage can be applied between the two conductive material layers to reduce or completely lose the viscosity of the electrical stripping adhesive layer 300, so that the user or the serviceman can remove the battery from the base 100 by a smaller pulling force. That is, the power utilization device provided by the embodiment of the application can improve the current situation that the battery can be detached from the base only by applying a large force, and further can reduce or eliminate the hidden trouble that the battery or the base is possibly damaged in the process of detaching the battery.
It should be understood that, even though the electric device 1 in the above embodiment includes the first conductive material layer 400 and the second conductive material layer 500 which are separately disposed with respect to the battery 200 and the mounting wall 110, so as to facilitate the application of the potential difference to both sides of the electric peeling glue layer 300, the present application is not limited thereto; in the power utilization device 1, the first conductive material layer and the second conductive material layer are provided on both sides of the electrical peeling adhesive layer 300. For example, fig. 4 and fig. 5 respectively show a schematic cross-sectional view of one direction of an electric device 1b according to another embodiment of the present application (the cross-sectional view may refer to the line A-A in fig. 1), and a schematic structural view of the electric device 1b when the base and the battery are hidden and the structure is unfolded in a straight state, and referring to fig. 1 to fig. 3, the electric device 1b includes a base 100b, a battery 200b, an electric peeling adhesive layer 300b, a first conductive material layer 400b separately disposed with respect to the battery 200b, and a first adhesive layer 410b for fixedly connecting the first conductive material layer 400b with the battery 200 b. The electric power consumption device 1b is mainly different from the electric power consumption device 1 in the above embodiment in that: the power utilization device 1b no longer comprises a second layer of conductive material and a second layer of adhesive, which are arranged separately with respect to the mounting wall 110. Specifically, in the present embodiment, the second conductive material layer is integrally formed with the mounting wall 110b, and the mounting wall 110b is a conductive region at a portion contacting the electro-peeling adhesive layer 300 b; in other words, the second conductive material layer is the mounting wall itself or a part of the mounting wall, and the electro-peeling adhesive layer 300b is directly adhered to the mounting wall 110b. For example, the mounting wall 110b includes a metal middle frame of the smart terminal, and a portion of the metal middle frame in contact with the electro-peeling adhesive layer 300b constitutes the second conductive material layer. In addition, in other embodiments of the present application, the second conductive material layer may also be coated on the side of the mounting wall 110b facing the electro-peeling adhesive layer 300 b; wherein, the coating mode can comprise one or more than two of electroplating, printing, coating or spraying. For example, the mounting wall 110b includes a non-metallic center of the smart terminal, and the second layer of conductive material is a conductive coating applied to a surface of the center.
For another example, fig. 6 and fig. 7 respectively show a schematic cross-sectional view of one direction of an electric device 1c according to another embodiment of the present application (the cross-sectional view may refer to the line A-A in fig. 1), and a schematic structural view of the electric device 1c when the base and the structure after the battery are hidden and unfolded in a flat state, please also combine fig. 1 to fig. 5, in which the electric device 1c includes the base 100c, the battery 200c, the electric peeling glue layer 300c, the second conductive material layer 500c separately disposed opposite to the mounting wall 110c, and the second adhesive layer 510c for fixedly connecting the second conductive material layer 500c and the mounting wall 110 c. The electric power consumption device 1c is mainly different from the electric power consumption device 1 in the above embodiment in that: the power consuming device 1c still comprises a first layer of conductive material, which is no longer provided separately with respect to the battery 200 c; accordingly, the power consuming device 1c no longer comprises the first adhesive layer. Specifically, in the present embodiment, the first conductive material layer is integrally formed with the battery 200c, and the housing of the battery 200c is a conductive region at a portion contacting the electro-peelable adhesive layer 300 c; in other words, the first conductive material layer is the battery case itself or a part of the battery case, and the above-mentioned electro-peeling adhesive layer 300c is directly adhered to the battery case. For example, the battery is a steel-case battery, and the portion of the steel-case battery in contact with the electrically-peelable glue layer 300c constitutes the first conductive material layer. Furthermore, in other embodiments of the present application, a first conductive material layer may be coated on a side of the battery 200c facing the electro-peelable glue layer 300 c; wherein, the coating mode can comprise one or more than two of electroplating, printing, coating or spraying. For example, cell 200c is a pouch cell and the first layer of conductive material is a conductive coating applied to the surface of the pouch cell.
For example, fig. 8 shows a schematic cross-sectional view of one direction of an electrical device 1d according to another embodiment of the present application (the cross-sectional direction may refer to the line A-A in fig. 1), and the electrical device 1d includes a base 100d, a battery 200d and an electrical peelable adhesive layer 300d in combination with other drawings. The main difference between the electricity consumption device 1d and the electricity consumption device 1b in the above embodiment is that: the power consuming device 1d still comprises a first layer of conductive material, which is no longer provided separately with respect to the battery 200 d; accordingly, the power utilization device 1d no longer includes the first adhesive layer; the remainder of the power consumption device 1d is the same as the power consumption device 1b described above. Specifically, in the present embodiment, the first conductive material layer is integrally formed with the battery 200d, and the housing of the battery 200d is a conductive region at the contact portion with the electro-peelable adhesive layer 300 d; in other words, the first conductive material layer is the battery case itself or a part of the battery case, and the above-mentioned electro-peeling adhesive layer 300d is directly adhered to the battery case. For example, the battery is a steel-case battery, and the portion of the steel-case battery in contact with the electrically-peelable glue layer 300d constitutes the first conductive material layer. In addition, in other embodiments of the present application, the first conductive material layer may also be coated on the side of the battery 200d facing the electro-peeling adhesive layer 300 d; wherein, the coating mode can comprise one or more than two of electroplating, printing, coating or spraying. For example, cell 200d is a pouch cell and the first layer of conductive material is a conductive coating applied to the surface of the pouch cell.
In addition, it should be added that, even though the first conductive material layer is directly a metal foil or a conductive non-metal sheet layer in the above embodiments, the metal foil or the conductive non-metal sheet layer is directly disposed between the electro-peeling adhesive layer and the first adhesive layer, but the application is not limited thereto. For example, fig. 9 is a schematic structural diagram showing a hidden base and a battery of an electrical device according to another embodiment of the present application unfolded to a flat state, and the electrical device also includes an electrical release adhesive layer 300e, a first conductive material layer 400e, a first adhesive layer 410e, a second conductive material layer 500e and a second adhesive layer 510e, in combination with other drawings. The main difference between the electric device and the electric device 1 is that: the power device further includes a first substrate layer 420e and a second substrate layer 520e.
Specifically, the first substrate layer 420e is located on the side of the electrically-peelable adhesive layer 300e facing the battery. The first conductive material layer 400e is coated on the side of the first substrate layer 420e facing the electro-peelable adhesive layer 300e, and is adhered and fixed to the electro-peelable adhesive layer 300 e; the first adhesive layer 410e is disposed between the first substrate layer 420e and the battery, so that the first substrate layer 420e and the battery are adhered and fixed. Wherein the first substrate layer 420e comprises a layer of polymeric material. Optionally, in this embodiment, the first substrate layer 420e specifically includes polyethylene terephthalate; of course, in other embodiments, the first substrate layer 420e may also include polyurethane, polyimide, and other polymers. The first conductive material layer 400e is coated on the first substrate layer 420e by at least one of electroplating, spraying, printing and coating processes; in this way, the thickness of the first conductive material layer 400e can be controlled to be in the micrometer level, even in the nanometer level, thereby contributing to the reduction of the overall material cost of the power utilization device. In addition, since the polymer is easier to realize a small size in thickness than the metal, and the thickness of the first conductive material layer 400e is also very small, this embodiment is also beneficial to reducing the thickness of the above-mentioned power device.
Similarly, the second substrate layer 520e is located on the side of the electrically-peelable adhesive layer 300e facing the mounting wall. The second conductive material layer 500e is coated on the side of the second substrate layer 520e facing the electro-peelable adhesive layer 300e, and is adhered and fixed to the electro-peelable adhesive layer 300 e; the second adhesive layer 510e is disposed between the second substrate layer 520e and the mounting wall, so that the second substrate layer 520e is adhered and fixed to the mounting wall. Wherein the second substrate layer 520e comprises a layer of polymeric material. Optionally, in this embodiment, the second substrate layer 520e specifically includes polyethylene terephthalate; of course, in other embodiments, the second substrate layer 520e may also include other polymers such as polyurethane, polyimide, and the like. The second conductive material layer 500e is coated on the second substrate layer 520e by at least one of electroplating, spraying, printing and coating processes; in this way, the thickness of the second conductive material layer 500e can be controlled to be in the micrometer level, even in the nanometer level, thereby contributing to the reduction of the overall material cost of the power utilization device. In addition, since the polymer is easier to realize a small size in thickness than the metal, and the thickness of the second conductive material layer 500e is also very small, this embodiment is also advantageous for reducing the thickness of the electric device.
Similarly, the arrangement of the first substrate layer and the second substrate layer is also applicable to the embodiments shown in fig. 4 and 6, and details of the specific implementation thereof will not be described herein.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the application, the steps may be implemented in any order, and there are many other variations of the different aspects of the application as described above, which are not provided in detail for the sake of brevity; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
