Referring to fig. 1 and fig. 2, which respectively illustrate an exploded view of an electric device 1 and a cut-away view of the electric device 1 along a line a-a according to an embodiment of the present disclosure, the electric 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 electrically peelable adhesive layer 300 is provided between the battery 200 and the mounting wall 110 to fix the battery 200 to the mounting wall 110. The electrical peeling adhesive layer 300 is formed by bonding a first conductive material layer 400 to a side facing the battery 200 and a second conductive material layer 500 to a side facing the mounting wall 110, and the electrical peeling adhesive layer 300 is formed to reduce or lose adhesiveness when a potential difference is generated 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 explained; however, it should be understood that in other embodiments of the present application, the power utilization device may be any device having a battery and driven by electricity, such as a sweeping robot, a fan, a shaver, and the like.
Referring to the base 100 and the battery 200, in particular, referring to fig. 1, the base 100 is a main body of the power consumption 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 has a mounting groove 101, and the mounting groove 101 has a rectangular cross section, so 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 a bottom wall 111 of the mounting groove 101 and opposite side walls 112 of the mounting groove 101. That is, the mounting 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 installation wall 110 is provided as above in the present embodiment, the specific shape of the installation wall 110 is various and the present application is not limited thereto. For example, in other embodiments of the present application, the mounting wall 110 does not include the bottom wall 111, 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 each of the side walls 112; for example, in other embodiments of the present invention, the battery 200 is not accommodated in the mounting groove 101, but is mounted on the outer wall surface of the base 100 through the electrically peelable adhesive layer 300, that is, the mounting wall 110 is the outer wall surface of the base; the specific arrangement of the mounting wall 110 is not described in detail here.
As to the electrically peelable adhesive layer 300, please refer to fig. 3, which shows a schematic structural view of the base 100 and the battery 200 hidden by the electric device 1 when the structure is unfolded to be a flat state, and referring to fig. 1 and fig. 2, the electrically peelable adhesive layer 300 is integrally in a sheet shape and is bent to be U-shaped, so as to be adapted to the mounting wall 110. The electrically peelable adhesive layer 300 is provided between the battery 200 and the mounting wall 110 in the thickness direction thereof, with one side thereof being disposed facing the mounting wall 110 and the other side thereof being disposed facing the battery 200. The electrically peelable adhesive layer 300 is an adhesive layer having adhesiveness which is reduced in adhesiveness or completely lost in adhesiveness when conductive elements are provided on both sides thereof and the two 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 electrically peelable adhesive layer 300, respectively, so as to achieve the above-mentioned object. Thus, when no potential difference is applied between the first conductive material layer 400 and the second conductive material layer 500, the electrically 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 adhesiveness of the electrical peelable adhesive layer 300 is reduced or completely lost, thereby reducing the fixing strength between the battery 200 and the mounting wall 110, thereby facilitating the user or the maintenance personnel to remove the battery 200 from the base 100. In this embodiment, the electrically peelable adhesive layer 300 includes a substrate and an adhesive disposed on both sides of the substrate, 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 power supply is used to apply a voltage to the first conductive material layer 400 and the second conductive material layer 500 on the opposite sides of the electrically peelable adhesive layer 300, anions in the electrolyte move to the surface of the electrically peelable adhesive layer 300 toward the positive electrode side, and cations in the electrolyte move to the surface of the electrically peelable adhesive layer 300 toward the negative electrode side; as such, the microstructure of the electrically peelable adhesive layer 300 is destroyed, and the adhesiveness thereof gradually decreases with increasing duration of the applied potential difference, or even completely loses adhesiveness. Therefore, when a user or a maintenance person needs to detach the battery 200 from the base 100, the battery 200 can be easily detached from the base 100 only by applying a potential difference between the first conductive material layer 400 and the second conductive material layer 500 for a predetermined time. It is understood that the structure of the electrical peeling adhesive layer 300 is various, as long as the adhesive force between the first conductive material layer 400 and the second conductive material layer 500 on both sides is reduced or completely lost after the electrical potential difference is ensured, and the application is not limited to the specific structure. For example, in other embodiments of the present application, the substrate of the electrical release liner 300 may be other polymer films with micropores, as long as the polymer films can allow ions to pass through, such as polyethylene terephthalate film; the adhesive may also comprise other polymeric 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 battery 200 and the mounting wall 110 will be described. In this embodiment, the power consumption device 1 includes a first conductive material layer 400 and a second conductive material layer 500 separately disposed from the battery 200 and the base 100, and further includes a first adhesive layer 410 for fixing the first conductive material layer 400 and the battery 200, and a second adhesive layer 510 for fixing the second conductive material layer 500 and 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 will be described in order below.
With reference to the first conductive material layer 400, please refer to fig. 1 to 3, wherein the first conductive material layer 400 is made of a conductive material, and the whole body thereof is also in a sheet shape and bent into a U shape matching with the electrical peeling adhesive layer 300. The first conductive material layer 400 is adhered to the side of the electrical peelable adhesive layer 300 facing the battery 200 in the thickness direction of the electrical peelable adhesive layer 300. Optionally, the first conductive material layer 400 includes aluminum, which is specifically an aluminum foil made of aluminum. It is understood that in other embodiments of the present application, the first conductive material layer 400 may also include other conductive materials; examples include metals such as copper, steel, gold, and silver, and further include non-metals such as graphite and graphene, and further include mixtures of at least two of the foregoing materials.
With reference to fig. 1 to 3, the first adhesive layer 410 is in a U shape matching the first conductive material layer 400. The first adhesive layer 410 has adhesiveness, and is disposed between the first conductive material layer 400 and the battery 200 to fix the first conductive material layer 400 and the battery 200. It should be noted that the material of the first adhesive layer 410 is various, and the present application does not specifically limit the material. For example, in some embodiments, first adhesive layer 410 comprises acrylic glue. For another example, in other embodiments, first adhesive layer 410 includes an epoxy glue. For further example, in still other embodiments, the first adhesive layer 410 includes an ultraviolet light reduced adhesive. The acrylic glue and the epoxy glue have strong viscosity and are easily remained on the surface of the battery 200 in the process of disassembling the battery 200; in contrast, the uv light anti-adhesive has better adhesiveness at room temperature, so that it can adhere to the battery 200; when the battery 200 needs to be disassembled, the first adhesive layer 410 can be cured into an integrated adhesive layer by irradiating ultraviolet light and the viscosity is reduced, so that a user or a maintenance person 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 alcohol reduced glue. The acrylic glue and the epoxy glue have strong viscosity and are easily remained on the surface of the battery 200 in the process of disassembling the battery 200; in contrast, the alcohol viscosity reducing adhesive has a better viscosity at normal temperature so as to adhere to the battery 200, and when the battery 200 needs to be disassembled, the alcohol viscosity reducing adhesive is swelled by dropping alcohol into the alcohol viscosity reducing adhesive so as to reduce the viscosity, so that the user or the worker can easily remove the first adhesive layer 410 from the surface of the battery 200. 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 this embodiment, in other embodiments of the present application, the electric 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 methods such as welding, and the fixing method of the first conductive material layer 400 and the battery 200 is not limited herein.
Referring to the second conductive material layer 500, with reference to fig. 1 to 3, the second conductive material layer 500 is also made of a conductive material, and the whole body thereof is also in a sheet shape and is bent into a U shape matching the electrical peeling adhesive layer 300. The second conductive material layer 500 is adhered to the side of the electrical release adhesive layer 300 facing the mounting wall 110. Optionally, the second conductive material layer 500 comprises aluminum, in particular aluminum foil made of aluminum. It is understood that in other embodiments of the present application, the second conductive material layer 500 may also include other conductive materials; examples include metals such as copper, steel, gold, and silver, and further include non-metals such as graphite and graphene, and further include mixtures of at least two of the foregoing materials.
With reference to fig. 1 to 3, the second adhesive layer 510 is shaped like a U corresponding to the second conductive material layer 500. The second adhesive layer 510 has adhesiveness, and is disposed between the second conductive material layer 500 and the mounting wall 110 to fix the second conductive material layer 500 and the mounting wall 110. The material selection of the second adhesive layer 510 can specifically refer to the first adhesive layer 410, which is not described herein.
When a user or a maintenance person needs to detach the battery 200, the user or the maintenance person only needs to apply a potential difference to the first conductive material layer 400 and the second conductive material layer 500 and maintain the preset time period T, so that the adhesive force between the electrically peelable adhesive layer 300 and the first conductive material layer 400 (or the second conductive material layer 500) is reduced to be below the preset threshold value, and the user or the maintenance person can easily remove the battery 200 from the base 100. It should be noted that the "preset threshold" mentioned in the present application refers to a value of an acting force that the battery 200 can be easily and manually detached from the base 100 without an external tool; for example, the predetermined threshold may be 0.2 kilogram force (kgf), or 0.1 kgf. The "preset duration" referred to in this document is related to the potential difference between the two layers of conductive material; for example, when the potential difference between the first conductive material layer 400 and the second conductive material layer 500 is 50V, the predetermined time period T is greater than or equal to 10S, which reduces the adhesive force between the electrically peelable adhesive layer 300 and the first conductive material layer 400 (or the second conductive material layer 500) to less than 0.1kgf, and when the potential difference between the two conductive material layers is 10V, the predetermined time period T is greater than or equal to 50S, which reduces the adhesive force between the electrically peelable adhesive layer 300 and the first conductive material layer 400 (or the second conductive material layer 500) to less than 0.1 kgf.
Further, in order to facilitate the user or the maintenance personnel to electrically connect the first conductive material layer 400 when disassembling the battery 200, the edge of the first conductive material layer 400 is provided with a first connection portion 401, and the first connection portion 401 exceeds the edge of the electrical peeling 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 relative to the electrical peelable adhesive layer 300 and/or the first adhesive layer 410, so that a user or a maintenance person can conveniently electrically connect the wires with the first connection portion 401. Similarly, in order to facilitate the user or the maintenance personnel to electrically connect the second conductive material layer 500 when disassembling the battery 200, the edge of the second conductive material layer 500 is provided with a second connecting portion 501, and the second connecting portion 501 exceeds the edge of the electrical peeling adhesive 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 relative to the electrical peelable adhesive layer 300 and/or the second adhesive layer 510, so that a user or a maintenance person can conveniently electrically connect the wires with the second connecting 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 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 according to the operation of the user, so that the adhesion between the electrically peelable adhesive layer 300 and the first conductive material layer 400, and/or the adhesion between the electrically peelable adhesive layer 300 and the second conductive material layer 500 are reduced to be below a predetermined threshold, so that the user can easily remove the battery 200 from the base 100. Specifically, the circuit board 600 includes a switch circuit electrically connected to the battery 200 to provide power 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, there is a potential difference 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 human-computer interaction, for example, a user or a maintenance person 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 above-mentioned switching circuit may be manually closed or opened by a user or a service person, and the present application is not limited thereto. It should be noted that the circuit board may be a main board of the intelligent terminal or a battery protection board in the intelligent terminal. Of course, in other embodiments, a 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 device on the market, the electric device 1 provided by the embodiment of the present application includes a base 100, a battery 200, and an electrically peelable adhesive layer 300. The first conductive material layer 400 and the second conductive material layer 500 are respectively bonded to two sides of the electrically peelable adhesive layer 300. Therefore, when a user or a maintenance person removes the battery 200 in the power consumption device 1 provided in the embodiment of the present application, a voltage is applied between the two conductive material layers, so that the adhesiveness of the electrically peelable adhesive layer 300 is reduced or completely lost, and the user or the maintenance person can remove the battery from the base 100 with a smaller pulling force. That is, the power consumption 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 acting 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-described embodiment includes the first conductive material layer 400 and the second conductive material layer 500 separately disposed from the battery 200 and the mounting wall 110, thereby facilitating the application of the potential difference to both sides of the electrical release adhesive layer 300, the present application is not limited thereto; as long as it is ensured that the first conductive material layer and the second conductive material layer are provided on both sides of the electrically peelable adhesive layer 300 in the electric device 1. For example, fig. 4 and 5 respectively show a sectional schematic view of one direction of an electric device 1b provided in another embodiment of the present application (the sectional direction can refer to line a-a in fig. 1), and a configuration schematic view of a configuration of the electric device 1b after hiding a base and a battery in a flat state when unfolded, and with reference to fig. 1 to 3, the electric device 1b includes a base 100b, a battery 200b, an electrically peelable adhesive layer 300b, a first conductive material layer 400b separately provided from 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 device 1b is mainly different from the electric device 1 in the above embodiment in that: the electric device 1b no longer includes the second conductive material layer and the second adhesive layer separately provided 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 in contact with the electrical peelable glue 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 electrical peelable adhesive layer 300b is directly adhered to the mounting wall 110 b. For example, the mounting wall 110b includes a metal middle frame of the smart terminal, and a portion of the metal middle frame contacting the electrical peelable adhesive layer 300b constitutes the second conductive material layer. In other embodiments of the present disclosure, the second conductive material layer may also be coated on the side of the mounting wall 110b facing the electrical peelable 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 middle frame of the smart terminal, and the second conductive material layer is a conductive coating applied to a surface of the middle frame.
For another example, fig. 6 and 7 respectively show a schematic cut-away view of a power consumption device 1c provided in another embodiment of the present application in one direction (the cut-away direction can refer to line a-a in fig. 1), and a schematic configuration view of a configuration of the power consumption device 1c after hiding a base and a battery in a flat state when the power consumption device is unfolded, and with reference to fig. 1 to 5, the power consumption device 1c includes a base 100c, a battery 200c, an electrically peelable adhesive layer 300c, a second conductive material layer 500c separately provided to face the mounting wall 110c, and a second adhesive layer 510b for fixedly connecting the second conductive material layer 500c to the mounting wall 110 c. The electric device 1c is mainly different from the electric device 1 in the above embodiment in that: the powered device 1c still includes a first layer of conductive material, but the first layer of conductive material is no longer separately disposed from the battery 200 c; accordingly, the powered device 1c no longer includes the first adhesive layer. Specifically, in the present embodiment, the first conductive material layer is integrally formed with the battery 200c, and the casing of the battery 200c is a conductive region at the contact portion with the electrically 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 electrically peelable adhesive layer 300c is directly adhered to the battery case. For example, the battery is a steel-can battery, and the portion of the steel-can battery in contact with the electrically peelable adhesive layer 300c constitutes the first conductive material layer. In addition, in other embodiments of the present application, a first conductive material layer may be coated on a side of the battery 200c facing the electrical release adhesive layer 300 c; wherein, the coating mode can comprise one or more than two of electroplating, printing, coating or spraying. For example, the battery 200c is a pouch battery, and the first conductive material layer is a conductive coating layer coated on the surface of the pouch battery.
For example, fig. 8 shows a schematic cut-away view of an electric device 1d provided in another embodiment of the present application (the cut-away direction can refer to line a-a in fig. 1), and with reference to the other drawings, the electric device 1d includes a base 100d, a battery 200d, and an electrical peelable adhesive layer 300 d. This electric device 1d is mainly different from the electric device 1b in the above embodiment in that: the powered device 1d still includes the first conductive material layer, but the first conductive material layer is no longer separately disposed from the battery 200 d; accordingly, powered device 1d no longer includes the first adhesive layer; the rest of the electric device 1d is the same as the electric device 1 b. Specifically, in the present embodiment, the first conductive material layer is integrally formed with the battery 200d, and the casing of the battery 200d is a conductive region at the contact portion with the electrically 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 electrically peelable adhesive layer 300d is directly adhered to the battery case. For example, the battery is a steel-can battery, and the portion of the steel-can battery in contact with the electrically peelable adhesive 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 electrical peelable glue layer 300 d; wherein, the coating mode can comprise one or more than two of electroplating, printing, coating or spraying. For example, the battery 200d is a pouch battery, and the first conductive material layer is a conductive coating layer coated on the surface of the pouch battery.
In addition, it is worth supplementing that, even though the first conductive material layer in each of the above embodiments directly adopts the metal foil or the conductive non-metal sheet layer, and the metal foil or the conductive non-metal sheet layer is directly disposed between the electrical peeling adhesive layer and the first adhesive layer, the application is not limited to this. For example, fig. 9 shows a schematic structural view of a power consumption device according to another embodiment of the present application after the base and the battery are hidden and the power consumption device is unfolded to a flat state, and in combination with other figures, the power consumption device also includes an electrical peelable 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 510 e. The electric device is mainly different from the electric device 1 in that: the electric device further includes a first substrate layer 420e and a second substrate layer 520 e.
Specifically, the first base material 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 one side of the first substrate layer 420e facing the electrically peelable adhesive layer 300e, and is fixedly bonded to the electrically peelable adhesive layer 300 e; the first adhesive layer 410e is disposed between the first base material layer 420e and the battery, so that the first base material layer 420e and the battery are bonded 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 other polymers such as polyurethane and polyimide. 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 at the micrometer level, even the nanometer level, thereby being beneficial to reducing the overall material cost of the electric 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 extremely small, this embodiment is also advantageous for reducing the thickness of the above-mentioned electric device.
Similarly, the second base material 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 electrically peelable adhesive layer 300e, and is fixedly bonded to the electrically peelable adhesive layer 300 e; the second adhesive layer 510e is provided between the second base material layer 520e and the mounting wall so that the second base material layer 520e is bonded 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 and polyimide. 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 at the micrometer level, even the nanometer level, thereby being beneficial to reducing the overall material cost of the electric 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 extremely small, this embodiment is also advantageous in reducing the thickness of the electric device.
Similarly, the arrangement manner of the first substrate layer and the second substrate layer is also applicable to the embodiments shown in fig. 4 and fig. 6, and details of specific implementation thereof are not described herein.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; within the context of the present application, where technical features in the above embodiments or in different embodiments can also be combined, the steps can be implemented in any order and there are many other variations of the different aspects of the present application as described above, which are not provided in detail for the sake of brevity; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
