Definitions
- the invention relates to portable electronic devices, and can be used in the construction of cases and removable panels for cell phones, smartphones, USB flash drives, laptops, etc.
- the disadvantage of the described device is its limited functionality, since such a manufacturing method involves the use of technology of deposition of metal on the matrix, which will not allow the casing to be made seamless all-metal, a relatively thick layer of metal is required for free removal from the matrix, which leads to an increase in the cost of the duration of the processes of electroforming and increasing the mass of the product, this technology limits the execution of walls with undercuts or with a deep complex re when building metal on thick-walled parts, it is difficult to ensure uniform wall thickness and avoid the appearance of dendrites, internal stresses and other defects, it is difficult to manufacture and remove “soft” precious metals from the matrix of walls, this technology is not provided for the production of light removable sticker overlays , which limits the consumer properties of portable devices.
- the basis of the invention is the task of developing a case of a portable electronic device, which provides the ability to make the metal case monolithic, in the form of one seamless part, reducing the weight of the case, the cost and time of the electroforming process, the ability to manufacture thin walls of the case from "soft" metals, making the case complex shape with a deep relief and undercuts, the execution of the metal wall in the form of a lightweight removable lining-stickers, increased rigidity and a housing, protection of the inner parts of the deposited dielectric coating the metal layer, corrosion protection and diversification of portable electronic devices.
- the claimed case is a portable electronic device consisting of external walls, electronic components are placed in the internal part of the housing, technological windows are made in the housing, at least one of the external walls of the housing is embossed using electroforming technology during electrochemical deposition of a metal layer moreover, a support core is additionally installed under the deposited metal layer, the support core is made of non-metal group material, the support core is rigid connected to the inner side of the deposited metal layer, the supporting core and the deposited metal layer form a structurally decorative panel.
- the case consists of external walls and serves to protect against mechanical damage, placement and access to the electronics of the portable device.
- At least one of the outer walls of the casing is made by the method of electroforming - the process of electrochemical deposition of a metal layer on a form that transmits an exact copy of the original model.
- a deposited metal layer is made of precious metals (silver, gold) or non-ferrous metals, in some cases, multilayer electroplating can be used (for example, gold-copper — cadmium — gold-silver).
- the deep relief can be high (high relief), low (bas-relief), in-depth, i.e. plane contour or other known shape.
- the deposited metal layer as a rule, has recesses formed by the relief.
- the supporting core serves to form a metal layer in the embodiment of deposition of metal on the core, reduce deformations during removal from the matrix, strengthen a thin layer of deposited metal, control the deposition of metal, acts as a dielectric, eliminating the occurrence of electrical faults on the inner deposited metal layer.
- the supporting core may be monolithic, in the form of honeycombs, with stiffeners, in the form of an unremovable embedded part, a set of several elements, or another known shape.
- fastening elements on the inner side of the support core, fastening elements (rivets, latches, clips, adhesive backings, screw connections, etc.) can be made to connect with other components of the portable electronic device.
- the supporting core is preformed in the form of a finished element or is poured into the interior of the deposited metal layer in the form of a compound (for example, epoxy or acrylic resin).
- the supporting core material is polymers (e.g. polyethylene, polyurethane, etc.), or composites - heterogeneous materials consisting of a binder and a reinforcing substance (e.g. fiberglass, carbon fiber, etc.).
- the support core in the form of a non-removable embedded part, serves to form the shape and topography of the housing.
- the embedded part may be in the form of a one-sided embossed wall or in the form of a spatial hollow body. This technology allows you to form a seamless monolithic body of metal in the form of a single integral part.
- technological and decorative windows, elements with undercuts, and a deep complex relief are predefined.
- the external parts of the embedded part are covered with a conductive layer (for example, graphite), after which the process of deposition of the metal layer.
- a conductive layer for example, graphite
- the support core in the form of a part attached to an already deposited metal layer, can be represented as a compound poured into the interior of the deposited metal layer followed by polymerization of the compound, or as a prefabricated element connected to the deposited metal layer by gluing, fixing or in another known manner.
- the process of connecting a thin-walled deposited metal layer with a supporting core takes place until it is disconnected from the matrix. After a hard connection of the deposited metal layer and the supporting core, extraction from the matrix takes place with a distributed load and is less likely to destroy or deform the metal layer - which will allow forming a structurally decorative panel of “soft” precious metals. This option allows the use of rigid, detachable or elastic matrices.
- connection of the support core and the deposited metal layer after it is separated from the matrix also takes the form of a compound pouring or connection with the finished support core. This ensures the rigidity of the structural and decorative panel, and the polymeric dielectric material of the supporting core will provide protection against possible electrical short circuits and corrosion.
- Structurally decorative panel can be made in the form of a housing element or in the form of a removable hard case, or a removable hard bumper.
- Structurally decorative panel can be made in the form of a lightweight removable lining stickers or in the form of a removable lining element (for example, as a decorative relief element made of metal mounted on a leather lining base).
- the lightweight removable pad can be rigid or flexible and mounts on a portable electronic device.
- An adhesive tape, adhesive base, or other known joining method may be installed as a connecting element on a lightweight removable pad.
- the inventive device operates as follows: structurally decorative panel is made by deposition of a thin layer of metal according to the technology of electroforming, while under the deposited layer, a support core of polymer or composite material is installed.
- the supporting core can be installed as a non-removable embedded part, or later connected to the deposited metal layer in the form of a compound filling or connection to the finished core.
- the polymer support core provides protection against short circuit and corrosion of the inner part of the deposited metal layer, allows you to perform fasteners on the inner side with other parts of the device.
- the inventive housing differs from the known additional installation of the support core under the deposited metal layer; the implementation of the supporting core from the material of the group of non-metals; rigid connection of the support core with the inner side of the deposited metal layer; the formation of a structural and decorative panel from the supporting core and the deposited metal layer.
